Hereditary factors that increase the likelihood of cancer mutations detailed in new study

A study of 11,000 cancer patients reveals 42 hereditary genes which predispose individuals to a higher number of mutations that correlate with a greater probability of developing cancer.
The research may lead to new personalized prevention and/or early detection strategies that assess a patient’s hereditary risk of developing different types of cancer.
The study is the result of a collaboration between the Institute for Research in Biomedicine and the Centre for Genomic Regulation. It is published today in the journal Nature Communications.
Mutations occur in various tissues and organs of an individual. Somatic mutations occur in cells that will not give rise to offspring and are therefore not passed on to subsequent generations. Caused by a large number of factors such as age and smoking, somatic mutations are the main cause of cancer and also play a role in other diseases.
A study led by ICREA researchers Dr. Fran Supek at the Institute for Research in Biomedicine (IRB Barcelona) and Dr. Ben Lehner at the Center for Genomic Regulation (CRG) has identified hereditary genetic traits that predispose individuals to the appearance of specific types of somatic mutations in their tissues. People with higher mutation rates in an organ are more likely to accrue mutations in key cancer genes which may increase the risk of tumour formation.
Researchers have previously described the hereditary mechanisms that predispose individuals to cancer, though many tumors do not have a clear genetic explanation. It is conceivable that cancer risk might result from changes in the spectrum of different types of somatic mutations, a common cause of cancer.

Study reveals why highly infectious cholera variant mysteriously died out

A new study reveals why a highly infectious variant of the cholera bug, which caused large disease outbreaks in the early 1990s, did not cause the eighth cholera pandemic as feared — but instead unexpectedly disappeared.
The study analysed samples of O139 Vibrio cholerae, a variant of the bacteria that causes cholera,and discovered significant changes in its genome over time that led to its unexpected decline.
These genetic changes resulted in a gradual loss of antimicrobial resistance (AMR), and a change in the types of toxin produced by the cholera bug. In combination, these changes are likely to account for O139’s failure to seed the eighth cholera pandemic.
The cholera bug is not currently monitored on a regular basis. Scientists say continuous monitoring of the genes underlying AMR and toxin production is key to keeping ahead of the cholera bug as it evolves. In particular, this will help to plan changes to vaccines and appropriate public health responses to prevent future cholera outbreaks.
The O139 variant of Vibrio cholerae was first detected in India in 1992. It quickly became dominant over the existing O1 variant and caused huge disease outbreaks in India and Southern Bangladesh.
The rapid spread of O139 across Asia surprised scientists, who feared it would cause the eighth cholera pandemic — and as a result cholera vaccines were modified accordingly. But for some reason that pandemic never happened: by 2015 the variant had largely declined, and the O1 variant established itself once again as a dominant strain. Until now, scientists have not understood why.

Fertility: Sperm screening might detect harmful mutations before embryo implantation

Screening sperm may help identify potentially harmful new genetic mutations and help fertility specialists prevent them from being passed on to offspring, shows a preliminary study published in eLife.
The results suggest a potential tool to help improve fertility treatment outcomes.
New harmful disease-causing mutations can arise in sperm, and fathers may inadvertently pass them along to their offspring during fertilisation. These mutations may cause miscarriages or lead to a child developing a congenital disease that neither parent has.
“Every male harbours up to dozens of these new mutations in their sperm, some of which are potentially harmful,” says co-senior author Martin Breuss, Assistant Professor in the clinical genetics and metabolism section of the Department of Pediatrics, University of Colorado Anschutz Medical Campus, Colorado, US. “But whether testing sperm for such mutations could help predict or prevent the risk of transmission to their children is unclear.”
Three couples undergoing in-vitro fertilisation treatments agreed to participate in the research. The investigators used whole-genome sequencing to detect new mutations in sperm samples from each man. They then tested preimplantation embryos at a very early stage of development from each couple for these mutations.
The team identified 55 mutations in the men’s sperm, including 15 passed on to an embryo. In some cases, more than one of a couple’s embryos had one of the mutations resulting in 19 cases of transmission. Mutations were passed on to the embryos slightly less often than the authors anticipated.
“Our results confirm that new mutations in sperm can be transmitted to embryos,” says co-lead author Xiaoxu Yang, a postdoctoral scholar at the University of California, San Diego, US. “Preimplantation genetic testing of embryos could be used to select embryos that did not receive one of the harmful new mutations detected in their father’s sperm.”
Previous studies by this team suggested that one in 300 children conceived through in-vitro fertilisation have a poor pregnancy outcome or poor health caused by a new mutation in their father’s sperm.
“If larger studies confirm our findings, this new approach could result in more positive outcomes for families struggling with infertility by helping prevent pregnancy loss or congenital diseases,” concludes senior author Joseph Gleeson, Director of Neurodevelopmental Genetics and endowed chair of Rady Children’s Institute for Genomic Medicine in San Diego, California, US.

Taking Vitamin D during pregnancy could lower the risk of eczema in babies

Taking Vitamin D supplements during pregnancy could substantially reduce the chances of babies up to a year old suffering from atopic eczema, according to a new study by University of Southampton researchers.
The research, published in the British Journal of Dermatology, revealed that babies had a lower risk of developing atopic eczema in their first year if their mothers took 1000 international units (IU) of Vitamin D a day from when they were 14 weeks pregnant until they delivered. The effect was particularly seen in babies who were later breastfed for more than a month.
Atopic eczema is a chronic inflammatory condition that can have a large impact on sufferers, their families, and healthcare. It is estimated that one in six children aged one to five has atopic eczema, and there has been a global rise over recent decades.
The study at the University of Southampton Medical Research Council Lifecourse Epidemiology Centre and the NIHR Southampton Biomedical Research Centre is the first randomised, controlled trial to show evidence of reduced risk of atopic eczema in infants of mothers who took Vitamin D supplements during pregnancy. More than 700 pregnant women took part in the research — with 352 taking the supplements from 14 weeks until they gave birth and 351 taking a placebo.
The eczema research was part of the UK Maternal Vitamin D Osteoporosis Study (MAVIDOS) and was led by Professor Keith Godfrey, working with Dr Sarah El-Heis, who was first author of the paper.
Dr El-Heis said: “Our aim was to see whether taking 1000IU of Vitamin D (cholecalciferol) as a supplement during pregnancy would decrease the risk of atopic eczema in babies. We also wanted to establish whether breastfeeding had any effect on this.
“Our results showed that babies of mothers who received supplements had a lower chance of having atopic eczema at 12 months, which supports recommendations for Vitamin D supplements to be routine during pregnancy.
“We found no effect at 24 and 48 months suggesting that other postnatal influences might become more important beyond infancy or that the babies themselves might also need to be supplemented during the postnatal period for a sustained effect.”
The MAVIDOS study also recently reported that taking the Vitamin D supplement during pregnancy also had lasting benefits for the child’s bone density at four-years-old.
Professor Godfrey commented: “We know that Vitamin D can affect the immune system and the proteins that make up our skin. We were interested to know if Vitamin D supplements taken by pregnant women would have an impact on their child’s risk of atopic eczema.
“Our findings showed a positive effect, which was more evident in infants that breastfed. This may reflect supplementation during pregnancy increasing the amount of Vitamin D in breast milk.”

His PTSD, and My Struggle to Live With It

Listen to This ArticleAudio Recording by AudmTo hear more audio stories from publications like The New York Times, download Audm for iPhone or Android.The night our world changed, I was in a copper baron’s palatial Adirondack home, writing about the history of the poorhouse. That afternoon, with the stained-glass reflections of autumn colors blazing through my window, I pored over an 1832 vendue contract auctioning the care of three female paupers to the lowest bidder in Sandown, N.H. I had taken a year’s unpaid leave from teaching at the State University of New York at Albany to write a book about technology and poverty. It was the first book I’d written for a popular press, the first written as a journalist rather than a scholar. I knew I had chosen risk: insecure income, shifting health insurance, a left turn from my career path that might not pay off. During my monthlong writing residency, I had no cell service, so I struck up an epistolary romance with Jason, my partner of 11 years. He told me about his dreams: a tiny U.F.O. banging against his shins, failing to abduct him; a nightmare about killing someone and fleeing the law. I confessed my discomfort with the retreat: I was writing about the 19th-century exploitation of the poor, the very people ground into mortar to build the storied estate where I was staying. On Oct. 8, 2015, I stepped out onto the veranda, in a vest and scarf against the cold. The fiery colors of the near-peak leaves had vanished, giving way to the night sky. I threw my head back in hopes of glimpsing a meteor shower. But the clouds obscured the Draconids, so at about 10 p.m., I went to the basement computers to check my email.From: “Jason Martin” Subject: Re: Yup!Date: October 8, 2015 at 6:14:34 PM EDTTo: “Virginia Eubanks” Virginia!bad nwews. I just got outta the ER where ive been for almost 24 hours. i jot jumped late last night by the deli. nobody I recognized. They kicked and punched me on the groupnd for a long time apparently. But the wierdestpart is how it passed so quickly and intensely I iddnt even have a reaction. I may have lost conciousess for a moment or two. cause next memory is sitting on chair in deli with cops asking questions. … oh wow so tired and so messed up right now. despite the good prognosis. . its takng all my energy to write this, so sorry for brevity and inabiity ti make it a more readable pieexoxoxoxoxoxjasonMy ears buzzed and my breath caught. I staggered to the residents’ phone booth. Rubbing my fingers nervously over the graffiti scratched by decades of artists into 100-year-old planks, I dialed Jason’s cell number, and his father answered. They were together. Jason was stable. But his jaw was broken in three places. A cheekbone broken. An eye socket. I was ready to jump into my ancient pickup and rattle home, but Jason’s dad deterred me. As much as I wanted to rush to his side, there was nothing I could do before morning but watch him sleep. If my truck broke down along the Northway, I would be stranded.I left the woods as the sun was rising the next day and arrived home to learn the details. Several men had beaten Jason unconscious less than two blocks from our home in Troy, the small city in upstate New York where we live. He was walking back from the corner store with Zebra Cakes and Camel Lights, and someone asked for a cigarette. When he turned to respond, he was hit the first time. He thinks there were four or five guys, all or mostly white, probably in their 20s and 30s. But he can’t be sure. He remembers just flashes: shoes in a circle around his head, waking up in the folding chair, a jagged moment of light and sound during the ambulance ride.It was good that he didn’t remember more. The damage to his face and skull required six and a half hours of plastic surgery to repair. That attack marked the beginning of our struggle to navigate a relationship transformed by trauma. Since then, I think I’ve read just about everything that has been written about how to support a loved one healing from post-traumatic stress. Among other things, I’ve discovered how devastating caregiving can be for those of us partnering someone with PTSD. While Jason’s diagnosis wouldn’t arrive for a few more months, and while my own clinical troubles would take years to emerge, that attack is an incandescent dividing line. Everything else — falling in love, building a life and our unknown future — now arranges itself in relationship to that moment, arrayed before or after what we call the Catastrophe.Illustration by Vartika SharmaWhen Jason and I got together in 2004, I was going through a numbing divorce from a man who left town with his best friend’s wife 10 days before I defended my Ph.D. dissertation. That I stayed in the relationship as long as I did left me feeling like a chump. “He was just your grad-school husband,” my friend Rachel consoled me over the phone. “Your self-esteem is so low in grad school.”Jason had been a friend for years. I was newly single, playing the field. Considering my options, I spied him in a crowded barroom and thought: Jason Martin — that would be fun. And I tipped my cowboy hat so it covered both our faces and kissed him. Jason resisted my attempts to get him into my bed, his slowly unfolding woo suggesting a longing for durability, for depth. I resisted his resistance, herding him toward shallow intimacies like a Border collie.Jason asked, “What are your three superpowers?” When I couldn’t identify any, his face drew together in mock concern. “Oooohh,” he said, shaking his head, “I can’t go out with you again until you know your superpowers.” Something in him sensed that my confidence was at a low ebb, and he wanted me undiminished, undimmed. The next time he called, I had a list: I can make anything taste good. I have a magic ray that makes everyone feel sexy. I see people as they really are.A musician and artist, Jason was a local celebrity in the Capital region. He lived in Schenectady in his early 20s and helped community members make TV shows for the local public-access cable station, creating operatically bizarre video art to play in late-night schedule slots. After a failed bid for City Council on the Green Party ticket, he moved to nearby Troy and opened a music studio and performance space. He created Power Animal System, a genderqueer art troupe, and performed all over the region, decked out in 1980s-era ladies’ business suits, wigs and wolf masks. When the independent newsweekly tired of trying to categorize his creative output — as poet, musician, producer, video and performance artist — it named him the region’s “Best Jason Martin” three years in a row.Where Jason went, community flourished. His superpowers were legion. He was at home anywhere. His mind was brilliantly unconstrained. He brought out people’s creativity, dragging them onto open-mic stages, shoving instruments into laughingly resistant hands. “Now you’re a musician,” he would say. “Play!” We feasted, profligate with our health and extravagant in our desire for each other. After roast pork shoulder and dark chocolate, we would smoke cigarettes in my apartment with greasy fingers, dancing to Captain Beefheart records and Ethiopian pop. We had what I took to calling “Lie Detector Sex.” Because I grew up in a household shaped by the secrets and separations of alcoholism, Jason’s emotional openness and physical fearlessness were both provocation and revelation.We faced struggles like any couple: I was more wounded by my divorce than I’d hoped; his boundary-pushing could shade into carelessness with my feelings. A few years after we started dating, he was diagnosed with bipolar disorder. His case was relatively mild and well controlled, with few of the symptoms that wreak so much havoc on relationships: no suicidal ideation, no sexual or financial shenanigans. He saw a psychiatrist regularly and adjusted medications when necessary. We saw a couples’ counselor when our relationship needed mending.I bought a house in South Troy in 2009, and we moved there together, filling it with talismans of our devotion. We sheetrocked a cartoon he drew of the two of us inside a first-floor wall. In the backyard, we planted a Montmorency cherry tree, known for its jewel-toned, half-sweet, half-sour fruit. We buried beneath it a tiny bundle — rose petals for romance, cinnamon for spice, our initials intertwined. We cemented a block print of the tarot card for strength — a woman holding open the jaws of a lion — under our threshold. Written on its back: “Protect this house, those who pass through it and the love that makes it a home.”The attack happened, by my count, 127 steps away from our front door.After Jason had plastic surgery on Oct. 23, 2015, the hospital didn’t keep him overnight for observation. Instead, they gave me a small set of wire clippers and told me that if the anesthesia or the pain made him sick, I should cut the wires holding his jaws together so that he wouldn’t aspirate on his own vomit. I curled myself into a tiny ball on the corner of the bed and watched him, terrified, holding the wire cutters, until I fell into a restless sleep near dawn. The next morning, I went to the drugstore to pick up his painkillers. The pharmacist informed me that the prescription had been canceled. The system showed we did not have health insurance. In a panic, I called our insurance provider. The customer-service rep assured me that it was a technical glitch and reinstated our prescription coverage so I could pick up Jason’s pills. But when I looked up our account on the company’s website, it showed that all our claims for the plastic surgery had been denied. We owed $38,962.47. That night, I moved into the small in-law apartment on the first floor of our house. I was listening to the internal voice that whispered I would need my sleep to get through what was to come. But also sharing a bed with Jason would be like sleeping with a fitful nuclear bomb. He radiated heat, sweated through the sheets, his arms flailed and his feet pedaled. Nightmares shocked him awake dozens of times a night. Understand Post-Traumatic Stress DisorderThe invasive symptoms of PTSD can affect combat veterans and civilians alike. Early intervention is critical for managing the condition.Removing the Stigma: Misconceptions about how PTSD develops and its symptoms, can prevent people from seeking treatment.Psychedelic Drugs: As studies continue to point to the therapeutic value of substances like MDMA, veterans are becoming unlikely advocates for their decriminalization.Seeking Peace: Mission Within is a Mexican retreat that uses hallucinogens to treat PTSD. Some female U.S. veterans and veteran spouses have turned to it to heal from trauma.Virtual Reality: A treatment using new technology to immerse patients in a simulation of a memory could help them overcome trauma.According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), trauma is an event involving “actual or threatened death, serious injury, or sexual violence” intense enough that it overwhelms a person’s ability to cope. Our bodies respond to trauma before we can apprehend the experience in our thoughts or feelings. Senses are heightened, adrenaline is released and the emotional and rational parts of the brain cede control to the autonomic nervous system, responsible for regulating primal bodily functions such as heart rate, digestion and respiration. The three most well-known responses to trauma are fight, flight and freeze. The fight response prepares the body for battle. A blinding rage gives you energy and tunnel vision, and you lash out at perceived attackers. The flight response prepares the body to run, compressing you into an unpredictable spring of kinetic energy. The freeze response shuts everything down and prepares you to survive a brutal onslaught. Fight, flight and freeze are all common, adaptive mechanisms for surviving assault, rape, battle or natural disaster. You have little conscious choice about which path you take when threatened with existential harm. A 2016 study estimated that more than 82 percent of Americans will experience at least one traumatic event during their lifetime. But according to national surveys, a much smaller number, about 4 percent of men and 10 percent of women, will develop post-traumatic stress disorder. I came to see the canonical symptoms of PTSD as mirrors of trauma responses. The intrusive thoughts, nightmares and flashbacks that psychiatrists call “re-experiencing” echo fight responses. Re-experiencing occurs when a sensory stimulus such as a sound, image, smell or even an invention of your dreaming mind — a trigger — pulls you back into the moment of trauma as if you are living through it again. Pathological vigilance, irritability and jumpiness, known as reactivity, feel like flight responses that have outlived their purpose. Avoiding people, places and activities that might trigger a trauma response recalls the body’s protective shutdown during freeze. Taken to its extreme, any of these symptoms can worsen into dissociation, essentially the mind splitting off into an altered state, resulting in blackouts and lost time. There is also another set of PTSD symptoms laid out in the DSM-5: negative thoughts and feelings that began or worsened after the trauma. This always seemed to me self-evident. Existential trauma is a stone-cold bummer. Many people who endure a traumatic event will experience nightmares, jumpiness and emotional numbing in its wake. A PTSD diagnosis, however, requires that symptoms last at least a month. PTSD is a disease of persistence. People who are bipolar, like Jason, are more likely to develop PTSD after a traumatic event than the rest of the population, though the etiology and symptoms of the two illnesses are entirely different. Bipolar didn’t change Jason’s fundamental character. When his depression was particularly acute, he retreated to rest and recover, but he remained a kind, open, creative and generous man, the partner I knew. PTSD was different. Illustration by Vartika SharmaFighting through the aftermath of the attack was exhausting. But it was also very simple, all action and no feeling. I experienced a state some partners of the chronically ill call survival euphoria. I picked the closest lion, and I wrestled it down. I fought to get Jason, in pain and frustrated, gasping and seething through metal and gauze, into his rusted 2008 Hyundai Accent after the plastic surgery that rebuilt his face and skull. I fought — in the end, successfully — to get our medical insurance reinstated and our medical debt cleared. I fought to manage the extraordinary generosity of our community. A fund-raiser to support Jason’s healing made the local news, and 200 people showed up. I had laryngitis, but I attended anyway. Wearing a long scarf, I didn’t say a word the entire evening, gesturing to my throat and shaking my head again and again. On Halloween, I blended fun-size Butterfingers in milk so Jason could drink them through his extra-wide smoothie straw. On Thanksgiving, I blended turkey, stuffing and chicken stock. I managed Jason’s medications, giving him his oxycodone and then hiding the bottle when he bellowed for more, like a drug-seeking bear, an hour later. Then, in December, Jason was leaving his first performance after the attack when a drunken homophobe perceived him as queer and tried to attack him in the street. While friends prevented the irate man from landing any punches, Jason endured verbal abuse, death threats and was chased through the street while his jaw was still wired from the surgery.After the second attack, he disappeared for three days, a stretch of time that he still doesn’t remember. By January 2016, a clinical psychologist had diagnosed him with PTSD.From the outside, our life looked normal. We hired a wonderful aide with the money from the fund-raiser, and with her help, Jason managed to keep his job as an adjunct instructor of video art at a local college. Jason attended weekly therapy sessions with a clinical psychologist specializing in trauma. He even managed to play a few gigs at house parties.But our private world was harrowing. Jason hid weapons behind doors and under beds. He had a special system for defending himself against imagined intruders: a brick to throw, then a bat to swing if they persisted and then, finally, a knife for up-close combat. He put plywood over the windows. Junk-food wrappers and dirty clothes piled up. Agoraphobia meant that the garbage didn’t always make it out of the house for pickup. A few dirty dishes were overwhelming, and they quickly morphed into impregnable piles. I stayed downstairs in my tidy bubble, mounting emergency cleaning expeditions to the second floor every few weeks. Even so, we endured a series of infestations: moths, ants and, finally, mice. I became hypervigilant about Jason’s hypervigilance, constantly scanning the horizon for threats. I worried that the laughter and trash talk of neighborhood kids would be too loud; that fresh baked bread would be too soft and he would tear it trying to butter it; that his keys would be misplaced or the car wouldn’t start on the first try; that it would be too hot or too cold, or too sunny or too rainy, that he wouldn’t have a warm jacket or sunglasses or a working umbrella at hand. Any one of these things transformed a normal morning into a tsunami of explosive rage followed by shuddering withdrawal. Blue skies, then the meteor, then the ice age.Leading lights in PTSD research — Janina Fisher, Bessel van der Kolk, Pat Ogden, Dan Siegel and others — like to talk about the crucial role “interpersonal neurobiology” plays in treating trauma. The theory is this: As social creatures, human beings learn from birth to regulate our emotions by interacting with others. Optimally, caregivers will respond to an infant’s hysterical cries with caring gestures: calm rocking, shushing. They will identify needs — Is the baby hungry? Wet? — and do their best to meet them. Good-enough caregiving, the theory goes, leads to secure attachment, and in that safe space a child learns to regulate his own emotions, meet her own needs. In other words, interpersonal neurobiology suggests that our ability to regulate our emotions doesn’t just arrive as we hit developmental milestones; it evolves in relationship with people around us. When we are hijacked into reliving a trauma or become withdrawn and shut down — what psychologists call dysregulated — we regain emotional balance as we once learned it: communally. Ruth Buczynski, president of the National Institute for the Clinical Application of Behavioral Medicine, suggests that “relationship is paramount” to healing trauma.Healthy relationships are both vaccine against PTSD and potential cure. Meta-analyses of existing studies in 2000 and 2003 found that poor relationship quality was among the strongest factors in developing PTSD after a traumatic event. A 2010 study found that good social support leads to increased improvement in patients seeking therapy for chronic PTSD. You need strong relationships to survive the kind of psychic wound Jason suffered during the attacks. The paradox is that trauma’s lingering impacts can enfeeble human connection, weakening even the strongest of social bonds. PTSD takes from us the very thing we need to heal from it.I tried to maintain some semblance of my former life: I worked on the book, started a new research project, was offered a job and briefly considered moving us both to Philadelphia. When I wasn’t working, I made appointments and returned calls: therapists, doctors, human resources, insurance companies, co-workers, family and friends. Jason kept going to therapy every week as the scars faded from his face. But he was dogged by insomnia — nightmares and hypervigilance kept him awake at night, and he spent most of his daylight hours watching TV and drifting in and out of sleep on the living-room couch. I scheduled meal deliveries and dropped off laundry at the fluff-and-fold. I looked for blackout curtains and white-noise machines on Amazon. I fought and fought.Then, I fled. On the first anniversary of the beating, I was in Los Angeles on a reporting trip. For the second anniversary, I was on the road, working on the new research project. When I was away, I desperately tried to feel something — anything — for myself. In Helsinki, Finland, to speak at a conference of Nordic social workers, I sat in a 190-degree smoke sauna and then padded outside, barefoot and mostly naked, to plunge into a hole in the ice in the Baltic Sea, over my head in the black near-freezing water, once, twice, three times. In 2016, I was on the road 147 days. In 2017, I was gone 97 days.We needed the money I earned through speaking engagements and research grants. But to claim that all my travel was materially necessary would be disingenuous. I wanted space and time away from the maelstrom of PTSD. I wanted to leave as much as I needed to leave.In December 2017, we decided to experiment with traveling together. Before the attacks, we were partners in adventure — we drove hundreds of miles of Route 20, visiting 1930s-era attractions: sifting through a museum of petrified creatures, spelunking in Howe Caverns, trying to choose a favorite roadside cheeseburger. We tramped the Adirondacks and floated in the Sacandaga reservoir. He ducked under security fencing to photograph crumbling 19th-century hotels while I kept lookout from the car. We wanted to try to recapture that feeling. We used all my Amtrak points to buy two round-trip tickets in a sleeper car for a seven-day trip to Montana for my mom’s 75th birthday. In theory, it was perfect: a tiny fishbowl of our own, traveling across the country at a leisurely pace. I imagined we would read, play cards. I bought a tiny electric kettle so we could make tea while the world passed outside the windows. In practice, it was a nightmare: a tiny fishbowl in which we were trapped together. Jason didn’t sleep. He was easily triggered and emotionally volatile. He snapped at me, other passengers, the conductor. I seethed and withdrew, thinking how much fun I would be having if I were alone. One night in January 2018, shortly after my father died, I came upstairs to share dinner with Jason, sad and exhausted and seeking comfort. “I’m feeling super vulnerable today,” I said. “So please let me know if you can’t be nice.” I’m not sure why that request precipitated the worst fight of our relationship. Perhaps it was the veiled suggestion that Jason had changed so much that he might hurt me when I was vulnerable, the insinuation that he was no longer the man he used to be. I remember that a look crossed his face, the look our cat gets when he has spotted a mouse — ears perked and gaze sharpened. I felt a malevolent part of Jason — a part I hadn’t imagined existed — turn its attention to me. I can’t remember much about the fight, but I know I felt like prey. I cried on the kitchen floor. Jason watched television nearby, silent and checked out as I sobbed. It felt as if I were living with an angry, cruel, terrified stranger who wore Jason’s face.The dark joke among PTSD caregivers is that your partner becomes the “T” in your own PTSD. PTSD researchers point out that during trauma, prey automatically orients to the predator, giving the threat all its attention. Jason oriented to people yelling outside the house, strangers on the street, angry white men on TV. I oriented to Jason. In August 2019, Jason and I shared two packs of American Spirits. We’d both quit smoking by then, but we decided that any time you get rejected by a mental hospital, you get to buy a pack of cigarettes. I’d just returned from a monthlong reporting trip in Iowa and Illinois for a story about government debt collection. Jason was in awful shape — the thousand-yard stare I knew meant dissociation, and under the surface of this blank, numb gone-ness, the simmering of unpredictable rage. I asked when he had last eaten. He said he didn’t know. I asked when he had last showered or changed his clothes. He didn’t know. I asked when he had last taken his medication. No idea. I called our couples’ therapist, and she suggested that I take him to the hospital, arguing that he needed inpatient treatment. “He’s not doing any of the things that are necessary to keep living,” she said, and coached me through what I should say when I tried to check Jason into a behavioral-health crisis center. Use the phrase “decreasing function,” she said. Use the phrase “passive annihilation.” We hoped for a three-day admission that might stabilize his medications and his mood, offer new possible treatments, and give us both a moment of rest. We waited in the E.R. for five hours, Jason sitting beside me wearing a ball cap pulled down over his eyes, sunglasses blocking his peripheral vision, hovering like a rabbit about to bolt. The unit was full, and as long as he was not suicidal or homicidal, the nurses finally told us, his care was a low priority. We were welcome to wait, they said, but it might be all night. The sounds of the hospital were triggering Jason’s PTSD, and he deteriorated as I watched. About half an hour after he curled up, fetal, on the floor of the E.R., I gave up and took him home. It had been almost four years since the attacks, and we had weathered it all with white-knuckled grippings onto our old life. Like a liturgy, we had assured ourselves time and time again that we were making real progress, that we were on the road back to normal. “We’re halfway through,” we had promised each other, six weeks after the attacks. “Halfway there,” we said at six months. And again at the one-year mark, and at the two-year mark: “Halfway,” we repeated with increasing desperation. “Halfway.”The failed attempt to get Jason into inpatient treatment wasn’t a simple setback. It was the moment we started to wake up to our new reality. There would be no back to normal.Jason’s PTSD was proving resilient, but not remarkably so: A 2018 study found that 50 percent of cases globally last more than two years, and 23 percent last more than 10. I read more clinical studies, trauma theory, memoirs and self-help books to understand, to interrogate, to find a way forward. Seeking fellow travelers, I pored over websites and online support groups. One author, assuming everyone with PTSD was a veteran, asked: “Is he more controlling since returning from war?” The book advised me to respond to attempts to restrict my activities and police my actions by “maintaining a sense of humor.” A website argued that because people with PTSD may fear abandonment, any suggestion that I might leave the relationship could “intensify their symptoms and make conflict worse.” Another book offered pointers on adjusting my communication style: I should drop everything I was doing and give Jason all my attention any time he spoke. I should maintain eye contact at all times. I should ask for permission to interrupt before I speak.“If at any point he looks bored or agitated, or starts shutting down or questioning your motives,” the book advised, “quickly summarize your reflections and stop.” The more I looked for help, the angrier I got. Most people with PTSD in the United States never served in the military, but much of the research on the subject in this country is funded by the Department of Veterans Affairs. So while there is little data on post-traumatic caregiving in nonmilitary families, research shows that the partners of veterans with PTSD “have a greater likelihood of developing their own mental-health problems.” Studies of Vietnam vets have shown that partners of those with PTSD report “lower levels of happiness, markedly reduced satisfaction in their lives and more demoralization” compared with partners of returning soldiers without PTSD. Caregivers also report stress, unmet needs and instances of physical and emotional violence in their relationships.The V.A. recognizes this and has tried to address it. As of June 2022, about 37,000 families were enrolled in the V.A.’s Program of Comprehensive Assistance for Family Caregivers. The program, established in 2010, provides training, health care and a small stipend for family members of seriously wounded veterans. A 2019 analysis by Katherine E.M. Miller and her colleagues found that caregivers in the program who received a modest stipend — $600 to $2,300 monthly — were able to work substantially less at their day jobs. There is no Program of Comprehensive Assistance for Family Caregivers of victims of community violence or rape. Researchers and psychologists call partners like me “supportive others.” The RAND Corporation calls caregivers of veterans with PTSD “hidden heroes.” Everyone seems to agree that we are crucial to healing. And yet, we are asked to paper over the cracks in institutional support systems with strips torn from our own skin. Without adequate assistance, we are offered two equally unthinkable choices: Martyr yourself or leave.The night we failed to get Jason into the mental hospital, I tucked him under a blanket on the couch, made him a hot cocoa and left him watching Netflix. I sat on the back porch, smoking a cigarette, making a hard decision: I had to stop traveling. I said no to dozens of invitations, slowly clearing my calendar, but I still had that article about government debt to finish. I was scheduled to do another monthlong writers’ retreat, so half a dozen of our most extraordinary friends stepped in to help. Each of them claimed a day to stop by, check that Jason had eaten, make sure he was taking his meds. They brought guitars, doughnuts, YouTube recommendations, gossip. Occasionally one of them would have to take Jason by the hand, lead him into the kitchen and ask him gently to eat something, spoonful by spoonful. It was an all-amateur, all-volunteer psych ward. Despite the evidence amassing in my journal, I had trouble admitting that I was exhibiting my own signs of PTSD: panic attacks, hypervigilance, emotional numbing, nightmares.Each week, I took a 14-hour round-trip train ride from Montauk to Albany to check in and make phone calls: hospital, therapist, insurance, repeat. The most stubborn obstacle was finding a psychiatrist to adjust Jason’s medications. It took five weeks to schedule a session. When I explained our situation through tears, begging for an emergency appointment, a receptionist responded, “They’re all emergency appointments.” While we waited, Jason was unable to teach his class. After finally getting a new prescription, he had to wait for the new meds to start working, and the rest of the semester slipped away. We were crushed when we received a letter from the university informing us his teaching contract would not be renewed. He was now officially out of work. I prepared to hunker down and accompany Jason through the maze of the unemployment and disability systems. Our income dwindled. My responsibilities doubled. Researchers sometimes talk about the communicability of PTSD as if it were a form of dark magic, the miasma of mental health, like the bad air once thought to cause plague. They suggest that caregivers suffer from vicarious trauma, that we catch secondhand symptoms from overempathizing, from simply imagining the assaults on our loved ones. Or that caregivers develop compassion fatigue because we fail to focus on our own well-being. In December 2019, I started to keep a journal. In it, I described almost comically transparent nightmares: dreams about broken pipes spewing water overhead, dreams of drowning. Though I’d made sure that Jason had a social network, my own relationships were strained. In the first year or so after the Catastrophe, we received such an outpouring of support that it was easy to feel grateful, surrounded by love. But after four years, my friends got on with their lives — had babies, moved, took new jobs — while part of me was still stuck in 2015. I had taken so much water out of the well of my friendships; I felt guilty sending the bucket down again. I was exhausted, and in my limited free time, all I wanted to do was go to the woods, sit in silence and do nothing. To revel in being responsible only for myself.In 2020, trying to dispute a medical bill that had gone into collections, I got stuck for most of an hour in a hellish labyrinth of broken voice prompts and singularly unhelpful call-center workers. After I hung up, billing error still unresolved, I began to pace, stalking back and forth in the cramped in-law apartment, mind racing, until my legs gave out underneath me. I cried so hard that one of my eyelids turned inside out, and then climbed into the hottest shower I could stand. I started taking deep breaths to calm down, but I was so out of control that I began to hyperventilate. Despite the evidence amassing in my journal, I had trouble admitting that I was exhibiting my own signs of PTSD: panic attacks, hypervigilance, emotional numbing, nightmares. Finally, I asked the psychologist I was seeing regularly to give me the Clinician-Administered PTSD Scale for DSM-5. I ranked up a symptom severity score of 33 out of 80, placing me in the “moderate” category. My PTSD diagnosis was possible because the DSM-5 designates that a “qualifying exposure” to trauma can occur in any of four ways: direct personal experience, witnessing trauma to others, repeated exposure to gruesome details of traumatic events or indirect experience through a family member. According to the DSM-5, my trauma originated in learning about Jason’s trauma; it arose in that moment when I stepped off the veranda beside that sylvan lake and checked my email. But I disagree.I believe my PTSD was caused not by empathy, or by referred suffering or burnout but by living with someone with PTSD and an avalanche of daily, direct “small-t” traumas: impossible paperwork, the broken health care system, mounting debt, a constant exhaustion that fed isolation from family and community. My traumatic exposures were the fruit of institutional failures: Every time Jason was denied resources he needed to heal, I was left to pick up the slack.The pandemic trapped Jason and me in the house together, for better and worse. Things deteriorated enough that we separated in July 2020, Jason moving into an Airbnb despite our Covid fears. He came back when we ran out of money, three weeks later. After hearing about Jason’s continued difficulty with focus and emotional control, our couples’ counselor suggested he might also be suffering from a traumatic brain injury. “Count backward from 100 by sevens,” she instructed him. “Spell ‘world’ backward.” Jason was laughing, but he couldn’t do it. It took us six months to schedule an appointment with a neuropsychologist. After performing a comprehensive series of tests, she reported that he most likely had a moderate traumatic brain injury, which worsened his psychiatric symptoms and resulted in cognitive deficits, based on his description of losing consciousness during the attack, his slowed mental processing, trouble with memory and problem-solving and — most troubling for a musician — diminished fine motor control. A neurologist might be able to give us more answers, offer new resources. It took us nine months to make that appointment, but we went to one together in October 2021. The neurologist didn’t see any evidence of a traumatic brain injury on Jason’s M.R.I. or electroencephalography, but he was deeply concerned about cardiac events that could result from his persistent insomnia. “Less than four hours of sleep a night will kill you,” we both remember the doctor saying. His clarity startled us into action. Jason moved off the living-room couch, where he slept most nights, and back into the upstairs bedroom. He shut off screens two hours before bedtime, established a sleep routine. Finally, he began to get real rest. Jason settled into a combination of Eye Movement Desensitization and Reprocessing (E.M.D.R.), sensorimotor and talk therapies. I relied on a cognitive behaviorist and a genius bodyworker who combines massage with internal family systems therapy. Jason meditated and arranged visits from friends; I guarded my time alone and hiked until my legs felt rubbery. And slowly, things started to improve. We reclaimed our house. We threw out what I had taken to calling “the depression couch.” We repainted the bedroom and rearranged the furniture. We put up a wall of pictures reminding us of better times. We were both done fighting and fleeing. We’d taken the relationship out of deep freeze and allowed it to thaw. We finally had the energy to look with an honest eye at what remained. What I saw was fear. Fear that he stays with me because I’m a good nurse. Fear that I stay because I’ve let my loyalty to him overwhelm my responsibility to myself.We’ve had sex only once in six years. “Let’s try to ease into intimacy,” my psychologist suggested. “Start by sitting back-to-back for a few minutes every day — you don’t even have to look at each other. Do some deep breathing. Observe your reactions.”So, most nights around sundown, Jason and I meet and sit on the living-room floor, back-to-back, for a few minutes. I look straight ahead. I resist my body’s urge to pull away. I examine my feelings. I would love to report that in these moments, I realize that PTSD has brought us closer, made us appreciate the small stuff, deepened our gratitude. But that’s not true. And yet, dozens of conversations about this essay have rekindled our commitment. We’ve stretched ourselves — sometimes painfully — to imagine the narrative from each other’s point of view. PTSD didn’t bring us together, but unraveling our story has begun to re-establish trust.We are different people now. Jason used to be able to talk to anyone: politicians, punks, professors, psychiatrists, psychics, plumbers. Now when he leaves the house, it is with hat pulled down over his eyes and keys bristling from his fist. He avoids grocery stores, the library, walking downtown.My superpowers have changed, too. While the kitchen is still full of grits and black-eyed peas, pickled beets and potpies, I haven’t dusted off the sex ray in years. And I’m not entirely sure I can see others — even Jason — as they really are anymore.But we persist. We play gin rummy together by candlelight after dinner. We borrow DVDs from the public library — “Spaceballs,” “The Thin Man,” “Booksmart” — movies with no punching to trigger Jason, and no sex, which just makes me too sad. Sometimes I put my foot on his thigh under a shared blanket.We’ve survived a catastrophe, barely, and maybe that’s enough. For now, we are aware of where we are and where we are not. We approach each other tenderly. We wound each other. We stumble and slide and try again.Virginia Eubanks is a journalist and teaches at University at Albany, State University of New York. She is working on a memoir about community violence, PTSD and caregiving.

Should You Put on Sunscreen or Foundation First?

Q: I wear a full face of makeup on top of a layer of sunscreen each day. Does that diminish my protection from UV rays?The key to reducing your risk of skin cancer, sun spots and wrinkles from sun damage is to incorporate sunscreen into your daily routine, and to apply it — and reapply it — correctly.Luckily, when it comes to wearing makeup and sunscreen together, there is some good news, said Dr. Nikhil Dhingra, a dermatologist at Spring Street Dermatology in New York City: No matter how much foundation, concealer, blush or highlighter you apply during your makeup routine, you’ll still be protected from the sun — as long as you follow a few simple steps.Apply products in the correct orderOne important way to ensure that you’re truly protected from harmful UV rays is to apply your sunscreen as the last step in your morning skin care routine, but before you begin applying any makeup.Chemical sunscreens contain filters that sink into the skin and absorb UV light, whereas physical (or mineral) sunscreens sit on top of the skin and scatter UV light. Because of these processes, sunscreen is most effective when applied directly to clean skin.After you wash your face in the morning and apply any skin care products, like toners, serums, moisturizers or oils, slather on your sunscreen. Dermatologists recommend using a minimum sun protection factor of 30.Wear enough sunscreenStudies have found that people generally don’t use enough sunscreen for adequate protection. Most only apply a quarter of the amount that they need for their entire body, said Dr. Amanda Doyle, a dermatologist at the Russak Dermatology Clinic in New York City. You need about two milligrams of sunscreen per square centimeter of skin to achieve the advertised SPF, according to the Skin Cancer Foundation.Because everyone is different, this could mean more or less sunscreen depending on the size of your face. To make application a little easier, Tiara Willis, a New York-based aesthetician, recommends the two-finger rule (lining the length of your middle and index finger with sunscreen) to measure an ample amount of sunscreen for your face and neck.Let it setBefore applying any makeup on top of your sunscreen, give it at least two minutes to sink into the skin. Avoid touching your face during this time. Dr. Kiran Mian, a dermatologist at Hudson Dermatology & Laser Surgery in New York City, said that adding makeup too soon could dilute your sunscreen or interact with the ingredients, rendering them ineffective.Think of putting on sunscreen like painting a room: Apply it in an even, thick coat, then give it enough time to dry before touching or decorating it. Dr. Mian suggested doing something like brushing your eyebrows after applying sunscreen to keep yourself busy in the interim. If your sunscreen base is properly dried and set, the ingredients in your makeup shouldn’t negatively affect its SPF.Aileen Son for The New York TimesDon’t rely on foundation with SPFMany foundations, beauty balms and color-correcting creams contain sunscreen, which can seem like a convenient way to protect your skin without compromising your makeup routine. However, makeup with SPF is not sufficient as your sole sunscreen option because you’d need to use a lot of it — more than most people typically use for their everyday looks — to effectively protect your skin.Of course, it doesn’t hurt to have added SPF from your makeup, because, when it comes to sunscreen, more is more. One study published in 2021 even concluded that layering makeup over sunscreen boosted total sun protection. This is because all makeup, even products that don’t have built-in SPF, contains filters similar to those found in physical sunscreens, which can provide added protection if your sunscreen base layer isn’t sufficient.Reapply sunscreen regularlySunscreen should be reapplied every two hours, or after swimming or sweating. Even sitting near a window while you work requires reapplication, because glass does not significantly block UVA or UVB rays. Usually, reapplication is as simple as smearing on another coat of sunscreen, but it can be trickier when you’re wearing makeup.The somewhat disappointing news: There aren’t enough studies to prove just how effective SPF reapplication on top of makeup is. And there’s reason to think it’s not ideal, because we know that sunscreen is most effective when applied as close to the skin as possible and because it’s challenging to apply enough sunscreen over makeup to be sufficiently protective. Powder sunscreens, for example, are an enticing option for reapplication because of their portability and utility as a quick touch-up tool, but in reality, said Dr. Cula Svidzinski, the medical director of the Skin of Color Center at Mount Sinai Medical Center, you’d need to apply about a teaspoon of powder sunscreen on your face to reach the advertised SPF.SPF setting sprays, and spray sunscreens in general, are appealing for their easy application, but the truth is that they still need to be rubbed into the skin to provide adequate coverage from the sun, which negates the presumed convenience.Also, keep in mind that SPF is not cumulative. “If your sunscreen is SPF 30, and then you apply an SPF 15 moisturizer, you don’t have SPF 45 protection,” Dr. Mian said.So, what should you do? Experts say that you should use any method that will encourage you to reapply your sunscreen, so long as you understand that you probably won’t be getting the full advertised SPF. Whether you reapply with a powder sunscreen, drown your face in an SPF setting spray or squirt sunscreen lotion onto the back of your hand and pat it on over your makeup, even a small SPF boost is better than nothing, the experts said.Caira Blackwell is a staff writer at Wirecutter who covers health and sleep.

Avabai Wadia: The lawyer who became India’s family planning pioneer

Published7 hours agoSharecloseShare pageCopy linkAbout sharingImage source, TopFotoIn 1933, a sari-clad teenager made international headlines. Avabai Wadia, 19, became the first woman from Ceylon (now Sri Lanka) to pass the bar exam in the United Kingdom. Her success encouraged the Ceylonese government to allow women to study law in the country.This was not the only time Wadia spurred government policies on women’s rights. By the time she died in 2005, she had become a globally respected figure in the family planning movement, combining a lawyer’s acumen with a dedication to socially uplifting women.Wadia was born in 1913 in a progressive Parsi family in Colombo. After qualifying as a lawyer, she worked in both London and Colombo despite omnipresent “masculine prejudice”. Why birth control is a woman’s burden in IndiaShe moved to Bombay (now Mumbai) during World War Two and immersed herself in social work, but found her true calling in family planning. “It seems my life work presented itself to me rather than my consciously searching for it,” she wrote in her autobiography, The Light is Ours. “I did not feel it a waste not to carry on with a legal career, for law was a fortifying element in all that I undertook.”When she began working in the field in the late 1940s, family planning was a taboo topic across much of the world. Aside from stoking opposition from religious conservatives, it also had ugly links with racism and eugenics. “The first time I heard the words ‘birth control’, I was revolted,” Wadia noted. But she was profoundly affected by a female doctor in Bombay who said that Indian women “oscillated between gestation and lactation until death wound up the sorry tale”. Image source, TopFotoDespite the threat of social ostracism, Wadia plunged into the cause. In 1949, she helped establish the Family Planning Association of India (FPAI), an organisation she would head for 34 years. FPAI’s work ranged from promoting contraceptive methods to providing fertility services – the latter gave Wadia “a real sense of satisfaction” since she had suffered miscarriages and had no children. It was in large part due to Wadia’s efforts that the Indian government became the first in the world to officially promote family planning policies in 1951-52.Under Wadia, FPAI adopted a decentralised, community-based approach, working with the urban poor and villagers from some of the most impoverished regions of India. India’s dark history of sterilisationThis meant that, quite often, the FPAI did “anything but family planning” – it undertook projects ranging from reforestation to road-building. Linking family planning with a holistic agenda of education, skill development and health, Wadia and her team employed creative communication techniques such as singing bhajans (devotional songs) with social messaging and organising a family planning exhibition which zipped across the country by train. FPAI’s innovative style of work fostered public confidence and led to marked improvements in development indicators. Image source, Hulton-Deutsch Collection/Corbis via Getty For instance, a project which began in the 1970s in Malur in Karnataka, resulted in reduced infant mortality, a significant increase in the average age of marriage, and the doubling of literacy rates. The project evoked such popular support that villagers took over its management after FPAI exited the scene.Perhaps due to her international upbringing, Wadia brought a global perspective to Indian family planning. Inspired by the success of South Korean mothers’ clubs, which bolstered widespread acceptance of family planning in rural areas, she organised close-knit groups where women could discuss pressing social issues ranging from dowry to female under-representation in politics. At the same time, she became a leading figure in the International Planned Parenthood Federation (IPPF), spotlighting the unique challenges faced by India in controlling its ballooning demographics.Politics further complicated these challenges. During the Emergency, which was imposed from 1975 to 1977, the Indian government adopted draconian population control measures including forced sterilisation. Wadia condemned this, warning against coercion in family planning programmes and declaring that participation had to be strictly voluntary. Family planning was beginning to show good results but, she lamented, the Emergency “brought the whole programme into disrepute.”In the early 1980s, Wadia faced another formidable challenge as president of the IPPF. She locked horns with the administration of US president Ronald Reagan, which cut funding from the country to any organisation which provided or endorsed abortion services. Although the IPPF did not officially promote abortion, some of its affiliates provided abortion services in countries where it was legal. Image source, Courtesy FPAIThe IPPF refused to cave into US pressure to change this arrangement, resulting in a loss of $17m in funding to its programmes. Wadia ridiculed the Reaganite notion that free market economics would combat population growth. Anyone who believed that, she averred, “has never been anywhere in the developing word – there are too many of the absolute poor, and you just can’t leave it to laissez-faire”.In many ways, Wadia’s career is of pressing relevance to contemporary dilemmas in family planning. In the United States, conservatives have argued that the reversal of abortion rights in Roe v Wade should be followed by reconsideration of rulings on contraceptive access. Wadia – who was involved in conceptualising India’s own abortion law – worried about how abortion could be weaponised in a larger movement against birth control. “Those who try to confuse the public by equating abortion with family planning,” she argued, “are trying to destroy human and individual rights.”Today in India, political debates abound about employing disincentives and coercive elements to restrict the sizes of families. Wadia cautioned against such approaches. “We cannot support disincentives which do not uphold basic human rights,” she said in 2000, when Maharashtra state – in a bid to enforce a two-child norm – considered stripping any third-born child of food rations and free primary education. “In practice, anyway, we have found that disincentives don’t work.”The myth of India’s population explosionThese events have demonstrated that family planning is intrinsically linked to law and politics. Perhaps it was fortuitous, therefore, that India had a pioneering female lawyer as one of the principal architects of its family planning movement.Above all, Wadia’s career is a reminder that family planning cannot be divorced from overall socioeconomic development.A few years before Wadia’s death, MS Swaminathan – the scientist who led India’s Green Revolution, which helped the country achieve food security – paid tribute to this fact. “More than anybody else,” he said, Wadia “knew that if our population policies go wrong, nothing else will have a chance to go right”.Parinaz Madan is a lawyer and Dinyar Patel is a historian.More on this storyWhy birth control is a woman’s burden in India27 JuneIndia’s dark history of sterilisation14 November 2014Row over rubber penis in India family planning kit22 MarchWhy do Indian women go to sterilisation camps?11 November 2014

Sri Lanka: 'I can’t afford milk for my babies'

Published7 hours agoSharecloseShare pageCopy linkAbout sharingImage source, Getty ImagesThe smell hits you first – freshly cooked rice, lentils and spinach, served in ladles from steaming pots. Dozens of families – including mothers with babies – are lined up with plates to get a serving of what will likely be their only meal for the day. “We are here because we are hungry,” says Chandrika Manel, a mother of four. As she kneads a ball of rice with her hands, mixing it with the lentils and spinach before feeding it to one of her children, she explains that even buying bread is a struggle. “There are times I [give them] milk and rice, but we don’t cook any vegetables. They’re too expensive.”Depleted foreign reserves and soaring inflation have devastated Sri Lanka’s economy in recent months. President Gotabaya Rajapaksa – who pushed through tax cuts that shrunk the state’s coffers and borrowed heavily from China to fund ambitious infrastructure projects – has been blamed for the crisis. The pandemic, which hit tourism, and the war in Ukraine, which sent oil prices rocketing, has only made the situation worse. But now Sri Lanka is on the brink of a humanitarian crisis, the United Nations Children’s Fund (Unicef) has told the BBC. The organisation found that 70% of the country’s families have cut down on food since the start of the year, and stocks of fuel and essential medicines are also fast running out. ‘My children are miserable’This is Ms Manel’s first visit to a community kitchen as she found her options disappearing: “The cost of living is so high, we are taking loans to survive.”The kitchen is a month old – Pastor Moses Akash started it in a church hall in Colombo after meeting a single mother who lived off a jackfruit for three days.”We get people who haven’t had a second plate of rice for the last four months,” Pastor Moses says. By his estimate, the number of people queuing up for food has grown from 50 to well over 250 a day. It’s not surprising given that food prices in Sri Lanka went up by 80% in June alone. “I see a lot of children especially, most of them are malnourished,” he says. ‘Living in my car for two days to buy fuel’What’s behind Sri Lanka’s petrol shortage?No medicine for kids in a collapsing health systemSahna, a pregnant 34-year-old who goes by her first name only, is also in the queue with her three young children. She is due in September and anxious about the future. “My children are miserable. They’re suffering in every possible way. I can’t even afford a packet of biscuits or milk for my babies.”Sahna’s husband, who is a labourer, earns just $10 (£8.20) a week to support the entire family. “Our leaders are living better lives. If their children are living happily, why can’t my children?” she asks. A looming humanitarian crisis By the time Sahna’s child is born, things are expected to get worse. The mayor of Colombo recently said that the capital has enough food only until September.With shortages of fuel and cooking gas, and daily power cuts, families are unable to travel to buy fresh food or prepare hot meals. Image source, Getty Images”Families can’t buy what they used to buy. They are cutting down on meals, they are cutting down on nutritious food. So we are definitely getting into a situation where malnutrition is a major concern,” said Christian Skoog, Unicef’s representative in Sri Lanka. “We’re trying to avoid a humanitarian crisis. We’re not yet at children dying, which is good, but we need to get the support very urgently to avoid that.”Unicef has appealed for urgent financial aid to treat thousands of children with acute malnutrition, and to support a million others with primary healthcare.Acute malnutrition rates could rise from 13% to 20%, with the number of severely malnourished children – currently 35,000 – doubling, says Dr Renuka Jayatissa, president of the Sri Lanka Medical Nutrition Association.The crisis has brought forth a sense of solidarity, with people often relying on the kindness of strangers. But even kindness and hope are becoming precious commodities. Dr Saman Kumara at Colombo’s Castle Street hospital says that if not for the goodwill of donors, his patients – tiny newborns – would have been at great risk. He says his hospital is now “completely dependent on donations” for essential medicines and equipment, and urged more donors to come forward as patients’ lives are in danger.Back at the community kitchen, Chandrika is scooping the last morsel of food into her son’s mouth. “My best days are done. But our children have so much ahead of them,” she says. “I don’t know what will happen as they grow up.”You may also be interested in: This video can not be playedTo play this video you need to enable JavaScript in your browser.More on this storySri Lanka warns petrol stocks about to run dry17 hours agoHow soaring cost of living is hitting Sri Lanka hard12 JanuaryWhat’s behind Sri Lanka’s petrol shortage?22 hours agoHow Sri Lanka’s war heroes became villains13 MaySri Lanka profile18 November 2019

Coevolution of mammals and their lice

According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals.
Reported in the journal Nature Ecology and Evolution, the study compared the genomes and family trees of lice and their mammalian hosts. The effort revealed that the two trees share a lot of parallel branches and twigs. Those branching points — where one group of mammals began diverging into new forms — often were echoed in the genomes of the lice that parasitized those mammals, the researchers reported.
“In this paper, we use data from genome sequencing to show that a major newly recognized group of mammalian lice, including lice of humans, originated on the common ancestor of Afrotheria, a group of mammals primarily of African distribution that includes elephants, hyraxes and elephant shrews, among others,” said Kevin P. Johnson, a principal research scientist and ornithologist at the Illinois Natural History Survey who led the study with Jorge Doña, a Marie Curie postdoctoral researcher at the University of Illinois Urbana-Champaign and the University of Granada, Spain. “These lice then went on to colonize other major groups of mammals through the process of host switching.”
The INHS is a division of the Prairie Research Institute at the U. of I.
Lice fall into two groups based on their eating habits. Chewing lice munch on skin or secretions, while sucking lice pierce the skin to consume the blood of their hosts, Johnson said. Both types feed on mammals, but sucking lice are exclusive to mammals.
Recent genomic studies revealed that sucking lice are closely related to two groups of chewing lice that also feed on mammals, and “each of the major groups within this newly identified lineage occurs on at least one member of Afrotheria,” the researchers wrote. Afrotheria is an ancient lineage of mammals that includes elephants, elephant shrews, hyraxes, golden moles, aardvarks and others.

Genetic atlas for zebrafish 'breakthrough' for biomedical research

Medical and life science researchers will benefit from the most comprehensive atlas yet of genetic data on zebrafish, newly published research suggests.
The atlas will help researchers to better study conditions from various types of cancer (e.g. skin cancer), heart disease, and neurodegeneration. It may help more researchers to replace mammal models in their studies.
The DANIO-CODE consortium, a nationwide team of 27 laboratories, worked together to catalogue published open-access datasets compensated with newly produced data. The effort resulted in 140,000 regions of DNA involved in regulating gene expression in zebrafish.
The study looking at zebrafish, the second most-used animal model for medical and life sciences research, draws on 1,802 samples with millions of data points each and provides the broadest picture of candidate DNA regions for transgenic breeding and genetic research into development and diseases.
Appearing in Nature Genetics today (Monday 4th July), the paper details DNA elements involved in several embryonic stages of development, and improvements to an understanding of the genetic equivalence between zebrafish and mice.
Ferenc Mueller, Professor of Developmental Genetics at the University of Birmingham who led the consortium of this study, said:
“The cataloguing of genetic information for zebrafish is a significant breakthrough that could underpin some of the most exciting medical and life sciences developments for years to come.
“Professor Boris Lenhard from Imperial College London and Professor Carsten Daub from Karolinska Institutet have been instrumental in coordinating over 50 researchers worldwide. The resulting atlas/map is a testament to how a bottom-up initiative for collaborating across borders can achieve impact for the benefit of our research community. The catalogue created by the DANIO-CODE consortium is open access to ensure that researchers can utilise the genetic information for their future studies.
“Zebrafish are an incredibly beneficial model for researchers. They are ideal candidates for studying various diseases and disorders because they grow transparently as embryos and have unusual regenerative properties. These properties have already given researchers insights into the human condition.
“Now, with our new catalogue, we move one step closer to having a fully realised map from which to overlay with the human genome. This kind of activity will allow researchers around the world to pursue at pace novel treatments, drugs, and a better understanding of the human and animal disease.”
Carsten Daub, Associate Professor and Group Leader, Department of Biosciences and Nutrition (KI) and Science for Life Laboratory at Karolinska Institutet who led the data integration said:
“This extensive study consolidates all individual datasets into one framework allowing researchers across the world to address questions which could not be addressed by the individual studies.”
