Living in hurricane affected areas could increase mortality of older people by 9% years after disaster
Researchers found increased, but regionally varying, risk of death from all causes for those who continued to live in flood-affected zip codes, highlighting the importance of region-specific disaster planning.

Hearing loss lowers prospects of employment and higher income for young Americans
Researchers analyzed data from 27,656 Americans between 23 and 43 years old in the ADD Health study. They found that participants reporting to have poor or worse hearing had significantly lower educational attainment, a lower probability of being in paid work, and earned less than their peers. These negative impacts of hearing loss were especially pronounced for Black and Hispanic Americans. Suffering from tinnitus was not found to have any effect on these outcomes. The authors propose better access to hearing care, early screening, and workplace support, as well as reducing stigma, to level the playing field for people with hearing loss.

Persistently, intensely grieving relations are nearly twice as likely to die within 10 years after losing a loved one
Researchers followed 1,735 people in Denmark over 10 years after their loss of loved one. 6% participants showed unabatingly high levels of grief symptoms, and these had a 88% higher hazard rate of dying from any cause over the time period than those with persistently low symptoms. The first group were likewise more likely to use healthcare services, with 186% higher odds of receiving talk therapy or other mental health services, and between 160% and 463% higher odds of being prescribed psychotropic medication. This is the first study on the long-term mortality rate and the use of healthcare in a large-scale cohort of bereaved persons. The results suggest that patients at risk for long-term ‘high grief’ may be identified in advance, and need additional support from the healthcare system.

Gene essential for vitamin D absorption could help unlock treatments for cancer and autoimmune diseases
Scientists have identified the human gene SDR42E1 as essential for the absorption of vitamin D from the intestine, its subsequent metabolic processing, as well as the production of lipids and steroids. Without the functional protein, the survival of cells dropped by 53%. This discovery has at least two potential applications in precision medicine. First, the experiments showed that the gene can be blocked to selectively kill cancer cells. Second, boosting SDR42E1’s expression could help treat many other diseases, for example, autoimmune and metabolic disorders, against which vitamin D and its related forms are thought to protect.

‘Molecular shield’ placed in the nose may soon treat common hay fever trigger
Researchers here developed a monoclonal antibody specific against mugwort pollen – an important allergen causing hay fever – in mice, which is highly effective in blocking symptoms of IgE immunoglobin-mediated allergy against this pollen. The monoclonal antibodies can be delivered inside the nose, rather than intravenously, acting almost like a ‘molecular shield’. The study is a proof-of-principle, which can be extended to other pollen species.

New gene therapy delivery device could let hospitals create personalized nanomedicines on-demand
Rare diseases affect millions worldwide, yet the one-size-fits-all model of drug development leaves patients with few treatment options. Now a European research project called NANOSPRESSO aims to tip the balance in patients’ favor by boosting access to low-cost bespoke gene and RNA therapies.

New ‘designer drugs’ pose growing threat to road safety in the US
Researchers from the US have reported the initial results from the first quantitative study to focus on the contribution of multiple new psychoactive substances (NPS) from a range of classes to roadway crashes in the US. They found that 2% of 1,000 adults who visited one of two trauma centers in California within six hours after being involved in a roadway crash had traces of NPS in their blood. The most frequent were bromazolam, para-fluorofentanyl, and mitragynine. In most (88%) of these positive cases, NPS had been taken together with traditional recreational drugs such as fentanyl, methamphetamine, and cocaine. These results indicate that NPS are a new concern in roadway crashes and put lives at risk.

Statins may reduce risk of death by 39% for patients with life-threatening sepsis
It has been suggested that statins could boost the chances of survival of patients with sepsis because of their multipronged effects on inflammation. Here, researchers from China used the MIMIC-IV database to perform a retrospective cohort study on two large, matched groups: critically ill patients with sepsis in the Beth Israel Deaconess Medical Center who received standard of care with or without statins. The 28-day all-cause mortality was 39% lower in relative terms [an absolute reduction from 23.4% to 14.3%] in the statin group, suggesting a protective effect. Previous randomized controlled trials that didn’t find any such benefit might have been too small or have had other weaknesses. The present results need to be confirmed in a large, well-designed randomized clinical trial.
