A community-wide intervention in South Africa aimed to improve parenting practices and children's mental health by making parenting programs and media messaging freely available across an entire community over three years. Positive parenting did not increase across the whole community, though there was a trend toward less physical punishment, and children's mental health improved by year three — possibly due to increased parental employment rather than the intervention itself. The findings suggest that addressing parental mental health, substance use, and domestic violence alongside parenting programs is essential for community-level change.

Researchers studied why PD-L1 — a protein used to predict which liver cancer patients will respond to immunotherapy — does not reliably predict outcomes in bile duct cancer (cholangiocarcinoma). They found that the proportion of dense connective tissue (stroma) within the tumor dramatically influences PD-L1 levels, and that PD-L1 distribution varies greatly even within a single tumor, meaning a small biopsy sample may not reflect the whole tumor's biology. These findings explain why PD-L1 testing is unreliable in this cancer type and highlight the need for better tissue-based biomarkers.

A single Swiss thoracic surgery center reported outcomes for 78 patients with stage III non-small cell lung cancer treated with immunotherapy-inclusive regimens — either neoadjuvant chemotherapy plus immunotherapy followed by surgery, or chemoradiotherapy followed by immunotherapy. Five-year survival was 78% in the surgical group and 30% in the radiation group, with treatment completion rates above 69% in both groups despite frequent but manageable complications. Complete pathological tumor elimination after neoadjuvant therapy was associated with 100% five-year survival.

A German randomized trial assessed whether a six-month group exercise program (ImPuls) added to standard outpatient mental health treatment is cost-effective for people with depression, PTSD, insomnia, or panic disorders. The program reduced psychiatric symptoms and improved quality-adjusted life years at a cost of about €17,500 per QALY gained — well within Germany's cost-effectiveness threshold of €30,000 — with a 77% probability of being cost-effective. Adding supervised group exercise to standard outpatient care appears to offer good value for mental health treatment.

Low-cost particle sensors are increasingly used to monitor hazardous dust in workplaces, but they tend to underestimate the true amount of particles in the air. This study found that recalculating particle mass from raw particle count data — using standard assumptions about particle size and density — reduced underestimation from 72% to under 5% without needing expensive reference measurements. This simple recalibration approach makes low-cost sensors more reliable for occupational health monitoring across different industries.

Plain English
Long-term real-world data from over 1,100 patients with unresectable stage III non-small cell lung cancer showed that consolidation treatment with durvalumab after chemoradiotherapy produced durable outcomes, with nearly half of patients still alive at five years. Median overall survival was 59 months, which is notably longer than what was observed in the original clinical trial that established this as standard of care. Benefits were seen across patient subgroups, including those with low PD-L1 expression and those who had received sequential rather than concurrent chemoradiotherapy.

Plain English
This trial protocol describes a study testing whether a 10-week video-call-based seated exercise program can improve mobility in stroke survivors who use walking aids and cannot easily participate in standing exercise. One hundred participants across five Canadian provinces will be randomly assigned to the seated exercise program or a control group, with mobility, balance, and quality of life assessed before and after. The study tests whether chair-based exercise can transfer to real-world walking ability in people with significant stroke-related mobility limitations.

Plain English
This real-world study of over 24,000 Dutch patients with high blood pressure found that women were more likely than men to be started on lower-intensity blood pressure medications and less likely to have their dose increased over time. Despite this, women were 16% more likely than men to reach their target blood pressure within six months. The findings suggest that even with less aggressive initial treatment, women achieve better short-term blood pressure control, though the reasons for the treatment differences require further investigation.

Plain English
Researchers interviewed 19 people diagnosed with cancer that met criteria for familial genetic testing to understand their views on being contacted directly by a cancer registry about testing options. Participants were broadly supportive of the registry reaching out to them, appreciating the use of existing health data to improve care, but wanted clear communication, data security assurances, and flexibility in how to act on the information. A registry-driven pathway was found acceptable, with preferences split between acting independently or having the registry contact their doctor.

Plain English
This policy paper from clinicians, economists, and policy experts outlines recommendations to improve early detection and treatment of cancer, reduce the burden of recurrence, and expand access to effective new therapies. Key recommendations include integrating early cancer care into national plans, using clinical endpoints beyond overall survival to speed up regulatory approvals, and ensuring new treatments — including immunotherapy — are accessible and reimbursed promptly. The paper calls for coordinated action across healthcare, policy, and research communities.

Plain English
Researchers found that the protein Semaphorin 7A plays a key role in guiding nerve fibers into fat tissue during early development and in triggering nerve regrowth in response to cold in adult mice. Mice lacking this protein had fewer nerve connections in subcutaneous fat and increased fat tissue mass in early life, with normal but blunted responses to cold in adulthood. Semaphorin 7A appears to be a critical signal coordinating the nervous system's control of fat metabolism.

Plain English
This meta-analysis pooled data from 21 studies on risk factors for unruptured brain aneurysms — balloon-like bulges in blood vessels that can rupture and cause stroke. High blood pressure and smoking were the only factors significantly associated with having an unruptured aneurysm, while diabetes, high cholesterol, and obesity were not. A major limitation is that almost no studies reported results separately for men and women, preventing analysis of sex-specific risk patterns despite women being disproportionately affected.

Plain English
A large UK randomized trial compared keeping oxygen levels at the lower end of normal (88–92%) versus above 94% in critically ill children on breathing machines. Children in the lower oxygen group had fewer days needing organ support and a lower risk of death at 30 days, with no difference in longer-term quality of life. The trial suggests that maintaining lower oxygen targets is both safer and cheaper for critically ill children requiring mechanical ventilation.

Plain English
This study surveyed 118 paleontological and Earth science databases to assess their longevity and the investment behind them. About 85% of community-curated databases survive less than 15 years, with peak losses coinciding with the end of typical 5-year funding cycles — putting decades of irreplaceable fossil and evolutionary data at risk. The authors call for sustained long-term funding, stronger institutional backing, and modular database architectures to preserve these scientific resources.

Plain English
Researchers reviewed 52 existing data repositories to identify which ones contain information useful for studying the long-term health effects of military exposures such as chemicals, radiation, and warfare agents in U.S. veterans. Of the 29 repositories analyzed in depth, eight met all six quality criteria covering exposure data, biological samples, and research permissions. These eight repositories are the most ready to support high-quality research that could inform veterans' disability policies and healthcare programs.

Plain English
This study examined the prognostic and predictive value of mutations in three genes — TP53, KEAP1, and STK11 — in patients with early-stage non-small cell lung cancer who underwent surgery, with or without chemotherapy. KEAP1 mutations were consistently linked to worse survival regardless of treatment, while disruptive TP53 mutations appeared to predict better response to adjuvant chemotherapy. The findings suggest these mutations could guide treatment decisions in localized lung cancer, though validation in larger studies is needed.

Plain English
The SenNet Data Portal is a public database housing molecular and imaging data from over 1,750 human and mouse datasets designed to help researchers study senescent cells — aged, dysfunctional cells that accumulate across tissues and drive aging-related decline. Built on a scalable cloud infrastructure, the portal integrates data across 15 organs and 6 measurement types, with tools for spatial mapping and cross-species comparison. It provides a centralized resource for the aging research community to discover biomarkers of cellular senescence and generate new hypotheses about age-related disease.

Plain English
Five-year follow-up data from the CheckMate 743 trial confirm that the combination of two immune checkpoint drugs, nivolumab and ipilimumab, extends survival in patients with unresectable pleural mesothelioma compared to chemotherapy. At five years, 14% of patients on the combination were still alive versus 6% on chemotherapy, and this benefit held even after accounting for patients who crossed over to immunotherapy after initially receiving chemotherapy. High levels of a certain immune-suppressing cell type at baseline were linked to worse outcomes, pointing to a potential biomarker for patient selection.

Plain English
This laboratory study tested how well polystyrene microplastics absorb a liver-damaging algal toxin (microcystin-LR) under freshwater and slightly salty water conditions, using two different particle sizes. Peak absorption reached only 4.6% even under the most favorable conditions, and was lower in freshwater and for larger particles. Polystyrene microplastics have limited capacity to act as carriers of this toxin in natural water bodies.

Plain English
This systematic review identified strategies for helping nurses and allied health professionals integrate genetic testing and counseling into everyday clinical practice. Workshops, online learning, and case-based education all showed positive effects on knowledge and confidence, while gaps remain in addressing motivation, habits, and professional identity. Future work should test these strategies more rigorously and address the underexplored psychological and cultural barriers to genetic practice adoption.

Plain English
Researchers surveyed 259 hospitalized heart disease patients about their willingness to use digital tools to manage their care after discharge. Overall acceptance was high, and the key factors driving acceptance were whether patients believed the tools would be easy to use, effective, and socially encouraged — with men showing somewhat lower acceptance than women. Developers of digital discharge tools should prioritize usability and perceived usefulness to maximize uptake in this population.

Plain English
This review examines how continuous-flow chemistry — running chemical reactions in a stream rather than in batches — improves the efficiency and safety of using C–H bonds as starting points for building new molecules. Flow systems offer better temperature control, faster reactions, and easier scaling compared to traditional batch methods, and are especially effective when combined with light-driven (photocatalytic) or electricity-driven (electrocatalytic) reactions. Together, these approaches enable greener, more resource-efficient chemical synthesis.

Plain English
This systematic review of 1,548 clinical trials in stroke rehabilitation catalogued which outcome measures are most commonly used to assess leg function and walking recovery. The Berg Balance Scale and 10-Metre Walk Test were among the most frequently used tools, and their use broadly aligns with clinical guidelines — but significant inconsistency remains, with 339 distinct measures identified across studies. This heterogeneity makes it difficult to compare treatments across trials and calls for greater standardization.

Plain English
A woman with a history of treated Hodgkin lymphoma developed progressive sensory nerve damage, an unusual pupil abnormality, and facial numbness over several years without a clear cause. Testing eventually revealed antibodies against FGFR3, a nerve protein, and treatment with intravenous immunoglobulin led to significant improvement. This is the first reported case linking FGFR3 antibodies to Adie pupil, adding to understanding of this rare autoimmune nerve condition.

Plain English
Healthcare professionals in pediatric rheumatology were surveyed to understand how they approach pain assessment and management differently for inflammatory versus non-inflammatory joint conditions in children. Pain assessment approaches were broadly similar for both condition types, but psychosocial treatments were viewed as less relevant for inflammatory conditions — despite pain always having biological, psychological, and social dimensions. The study highlights a gap between current evidence-based guidelines and clinical practice, particularly around pain care for conditions like juvenile idiopathic arthritis.

Plain English
Researchers used a nationwide algorithm integrating health records, insurance claims, and prescription data to measure Parkinson's disease incidence across the Netherlands from 2017 to 2022, identifying over 22,000 new cases. Rates were stable over time, peaked in the 75–85 age group, were higher in men, and were unexpectedly elevated in northern provinces and among people with higher socioeconomic status. These regional disparities do not align with obvious environmental factors like air pollution or farming, suggesting unknown drivers warrant further study.

Plain English
Scientists engineered mice with targeted changes in the tau protein — specifically in a region that binds other proteins involved in seizure activity — to see if they could block the harmful effects of tau without eliminating the protein entirely. Mice with one specific mutation showed resistance to chemically induced seizures, improved sleep, and reduced epileptic brain activity, while maintaining normal movement and memory across aging. This precision approach to tau modification may offer a safer therapeutic strategy for Alzheimer's-related seizures and sleep problems than fully removing tau.

Plain English
This study investigated which patients with unresectable stage III lung cancer treated with durvalumab after chemoradiotherapy are most likely to develop lung inflammation (pneumonitis). Among 268 patients, those who received higher radiation doses to the lungs and those with pre-existing COPD had roughly two to three times the risk of developing significant pneumonitis. These findings can help clinicians identify high-risk patients who need closer monitoring during durvalumab consolidation therapy.

Plain English
Researchers evaluated whether PET/CT scans — which measure metabolic activity in tumors — can predict how well lung cancer responds to chemotherapy plus immunotherapy before surgery. A 70% drop in lymph node metabolic activity on the post-treatment scan predicted complete tumor elimination with 88% sensitivity and 78% specificity, and also correlated with better long-term survival. PET/CT assessment of lymph nodes appears to be a more useful predictor of treatment response than measuring the primary tumor alone.

Plain English
Women who have had preeclampsia during pregnancy face an elevated long-term risk of heart disease, but no clear standard exists for reducing that risk. This systematic review found only eight relevant studies, covering exercise, web-based tools, blood pressure monitoring, and multidisciplinary clinics — all showing some benefit, but none large enough to guide definitive recommendations. The review concludes that early education, structured exercise, and digital tools are likely key components of an effective strategy, but larger studies are needed.

Plain English
Researchers pooled data from 14 European and Canadian case-control studies to test whether workers exposed to chlorinated solvents face a higher risk of lung cancer. Overall, exposure to these chemicals was not significantly linked to lung cancer risk, though there was a modest increase (11%) among people exposed for 20 or more years. The evidence remains limited and does not firmly establish chlorinated solvent exposure as a lung cancer risk factor.

Plain English
This study looked at how often serious side effects occur in children receiving proton beam radiation therapy for brain and spinal cord tumors, and whether adding chemotherapy at the same time makes things worse. Among 199 children treated, serious adverse events occurred in about one-third of cases overall, but in nearly two-thirds of those who received chemotherapy alongside radiation — mainly due to blood toxicity and infections. The findings confirm that concurrent chemotherapy during proton therapy is manageable but requires close monitoring and experienced teams.

Plain English
This phase 2 trial tested whether combining two immune checkpoint drugs — domvanalimab (targeting TIGIT) and zimberelimab (targeting PD-1) — works better than either drug alone or chemotherapy as a first treatment for advanced lung cancer with high PD-L1 expression. The combination showed longer progression-free and overall survival compared to the single drug, with a 31% reduction in the risk of disease worsening, and had a lower rate of severe side effects than chemotherapy. These results support further investigation of the dual immunotherapy combination in this patient group.

Plain English
This study examined the experiences of non-uniformed workers — such as construction, utility, and transportation staff — who responded to the 9/11 World Trade Center disaster, a group that has been largely overlooked in emergency management research. Interviews with 26 knowledgeable insiders revealed that these responders felt invisible and left out of support systems designed primarily for uniformed personnel. The findings highlight the need for better preparation, training, and mental health support for non-uniformed responders before and after future disasters.

Plain English
This trial protocol describes a study testing whether combining two brain and muscle stimulation techniques — repetitive transcranial magnetic stimulation (rTMS) and functional electrical stimulation (FES) cycling — can improve leg function in people with incomplete spinal cord injury. Fourteen participants will be randomly assigned to receive either real or sham rTMS before each cycling session over six weeks. The pilot aims to confirm whether the combined approach is safe and feasible before a larger trial is launched.

Plain English
An international panel of lung cancer specialists developed consensus guidelines on how to obtain and handle tissue samples for testing in non-small cell lung cancer, where precision medicine depends on accurate molecular analysis. The panel agreed that biopsy site and technique should be chosen based on disease stage, tumor location, and the need to obtain enough tissue for both diagnosis and staging simultaneously. These recommendations aim to reduce the wide variation in biopsy quality seen in real-world practice.

Plain English
This study examined whether healthcare worker burnout and thriving at work predict who actually quits their job, not just who says they intend to quit. Burnout was linked to both the intention to leave and actually leaving, but feeling satisfied at work only predicted intention — not actual turnover. Using intention to leave as a stand-in for real turnover can be misleading in workforce research.

Plain English
Researchers tested whether a higher dose of heparin (a blood thinner) could better prevent dangerous clots in critically ill COVID-19 patients compared to the standard lower dose. In a large international trial, the higher dose did not improve survival or reduce the need for organ support, while bleeding rates were similarly low in both groups. Standard low-dose thromboprophylaxis remains the appropriate approach for this patient population.

Plain English
Scientists analyzed the gravitational wave signal GW250114 — the strongest ever detected — to test whether the black hole produced by the merger behaves exactly as Einstein's general relativity predicts. The analysis confirmed at least two distinct oscillation modes in the signal and measured their frequencies to within a few percent of theoretical predictions, providing the most stringent single-event test of general relativity to date. These results validate both the theory and the Kerr description of black holes with unprecedented precision.

Plain English
This review evaluates clinical trial evidence on whether immunotherapy — given before surgery, after surgery, or both — improves outcomes in patients with resectable non-small cell lung cancer that lacks targetable gene mutations. Eight phase III trials across different treatment timings all demonstrated survival benefits from adding immunotherapy to standard care. The review discusses how to select patients, choose the best treatment timing, and use response assessments to guide escalating or reducing treatment intensity.

Plain English
This chapter reviews how occupational health researchers assign standardized job codes to workers' free-text job descriptions — a labor-intensive step needed before exposure tools can be applied in large population studies. Current automated systems struggle to generalize across different datasets and job description formats, limiting their real-world use. Large language models are proposed as a promising but underexplored tool to improve the accuracy and adaptability of automated occupational coding systems.
