Researchers studied why diabetic patients suffer worse lung damage during pneumococcal pneumonia. They found that high blood sugar amplifies a chain reaction — starting with an enzyme called NOX1 — that floods lung cells with calcium and destroys the lung's protective barrier. Targeting any step in this NOX1–calcium pathway could become a strategy to protect diabetic patients from severe pneumonia.

Plain English
This study examined what happens to the choroid plexus — a brain structure that produces cerebrospinal fluid — when the anti-aging protein klotho is deleted specifically there. Removing klotho caused abnormal calcium deposits in the choroid plexus, with the timing and location of these deposits depending on brain region and age. Despite this calcification, the mice showed no cognitive problems, suggesting the brain partially compensates before structural breakdown occurs.

Plain English
Researchers tracked which medical specialists treated liver cancer patients across three Mayo Clinic sites over five years. Interventional radiology handled the most first-line treatments — especially for early-stage disease — while medical oncology led for advanced stages, and hepatology coordinated care for nearly all patients. The findings reveal how the treatment of this complex cancer is genuinely shared across specialties, which has practical implications for staffing and resource planning.

Plain English
Scientists determined the three-dimensional structure of a small RNA molecule called the B2 SINE ribozyme, which shuts down gene expression during cellular stress. A specific region of the RNA acts as the structural and functional core — controlling both its self-cutting activity and its ability to silence genes. Understanding this structure opens the door to manipulating stress-response gene regulation.

Plain English
This qualitative study interviewed schizophrenia patients who switched to a new drug called xanomeline/trospium, which works differently from all other antipsychotics by targeting muscarinic receptors instead of dopamine. Over 60% of patients reported meaningful symptom improvement within six weeks, rising to about 80% by six months, spanning hallucinations, motivation, and concentration. Patients described these gains as real improvements in daily life, not just symptom scores.

Plain English
A deep learning model called TRI_IF was built to measure kidney scarring (interstitial fibrosis) directly from biopsy slide images, without requiring pathologists to manually mark the tissue. The model matched expert pathologist assessments closely and accurately predicted which patients would progress to kidney failure. This approach could standardize fibrosis measurement across labs and reduce the inconsistency of current visual grading.

Plain English
This study investigated how two fatty acid additives — one standard, one fluorinated — change the shape of a type of polymer particle called a Tetronic micelle. The regular fatty acid caused micelles to grow and reshape from spheres into elongated and then vesicle-like structures by dehydrating the outer layer and packing the core more tightly, while the fluorinated version had little structural effect despite binding more strongly. The key driver of shape change is physical compatibility with the micelle core, not just chemical attraction.

Plain English
Scientists designed a new class of antibiotic that blocks bacteria from starting gene transcription, targeting the interface between RNA polymerase and its helper protein sigma rather than the active site — which is where resistance to current antibiotics like rifampicin develops. The best compound found bound tightly to the target protein and killed both E. coli and S. aureus in lab tests. This non-competitive approach could be harder for bacteria to develop resistance to.

Plain English
Researchers built a machine learning framework to classify the four molecular subtypes of triple-negative breast cancer — the most treatment-resistant form — using gene expression data from nearly 800 tumor samples. A Random Forest model achieved 96% accuracy and identified 47 genes, including CDC20 and KIF2C, as key drivers distinguishing the subtypes. These biomarkers could guide more targeted treatment decisions for patients with this aggressive cancer.

Plain English
A 29-year-old woman presented with a rare benign kidney tumor called metanephric adenofibroma — a type normally seen in children — causing intermittent flank pain. Surgeons removed the tumor robotically while preserving the kidney, and pathology confirmed it was non-cancerous with clean margins. The case highlights that this pediatric tumor can appear in adults and does not require aggressive treatment.

Plain English
A 15-month clinical trial in Chicago tested whether risk-tailored PSA screening guidelines — adjusted for race, family history, and prior PSA levels — could increase prostate cancer detection in a high-risk, majority-Black population. Screening rates nearly doubled, biopsies increased, and total prostate cancer diagnoses rose 2.7-fold, with no change in the proportion of aggressive tumors found. The results show that risk-adapted guidelines are practical in community health settings and can meaningfully increase cancer detection in underserved populations.

Plain English
This study examined whether COVID-19 drove higher antibiotic use and bacterial infections in hospitalized patients across six South American hospitals. COVID-19 patients were actually less likely to have confirmed bacterial or fungal infections, and antimicrobial use was not significantly higher in COVID-positive patients compared to COVID-negative ones during the same pandemic period. The commonly reported surge in antibiotic prescribing during the pandemic was not evident in this cohort.

Plain English
Scientists engineered a small protein domain called MTD4 that can carry any attached protein or peptide directly into the interior of cells — a long-standing challenge for protein-based drugs. MTD4 worked at very low concentrations, delivered cargo to both the cytoplasm and nucleus, and spread broadly through mouse tissues after injection. This plug-and-play delivery system could unlock treatment of diseases caused by proteins inside cells, which current antibody drugs cannot reach.

Plain English
This is a published correction to an earlier article on placental epigenetic clocks and biological aging in obstetrics; no new findings are presented.

Plain English
Surgeons proposed a six-category classification system for the defects left behind after removing oral cancers from the cheek and gum region, based on how deep the cancer went and whether bone was involved. The system progresses from surface-only defects to full-thickness wounds that penetrate through the cheek skin, with or without jaw bone removal. A standardized classification like this makes it easier to plan reconstruction, compare outcomes across centers, and train surgeons consistently.

Plain English
Researchers mapped how a human RNA molecule called RMRP behaves structurally and what proteins it works with inside cells. RMRP changes shape depending on magnesium levels, interacts with two RNA-unwinding proteins (DDX5 and DDX3X) that guide it to mitochondria, and when depleted, causes mitochondrial damage and oxidative stress by dysregulating specific mitochondrial proteins. This identifies RMRP as a key regulator of mitochondrial health with relevance to diseases caused by RMRP mutations.

Plain English
Plant geneticists identified the chromosomal regions that give certain watermelon varieties resistance to race 2 anthracnose, a destructive fungal disease. Using both family-based and population-wide genetic mapping, they pinpointed three resistance loci on chromosomes 3, 6, and 8 near genes encoding immune receptor-like proteins. These markers can now be used in breeding programs to develop disease-resistant watermelon varieties.

Plain English
This randomized trial compared two nerve block techniques for pain control after open inguinal hernia repair: the established transversus abdominis plane block and a newer quadratus lumborum block. The two techniques provided equivalent pain relief, opioid use, and complication rates, meeting the trial's non-inferiority threshold. Either block is a reasonable choice, and surgeons can select based on their experience and patient factors.

Plain English
A systematic review of nine studies compared patients who were taken off the ventilator within four hours after robotic heart bypass surgery versus those kept on longer. Early extubation shortened ICU stays and hospital stays by up to four days and did not increase the risk of irregular heart rhythms, reintubation, or death. These results support including early extubation in recovery protocols for carefully selected bypass surgery patients.

Plain English
This systematic review analyzed studies of heart attacks in adults under 40 to identify risk factors that go beyond the usual ones like smoking and high cholesterol. HIV infection, lupus, obstructive sleep apnea, depression, and biological aging (shorter telomeres) each carried substantial risk — sometimes doubling or quadrupling the odds. Adding these non-traditional factors to risk prediction models could help identify young people at elevated risk before a heart attack occurs.

Plain English
Scientists discovered that a tiny alternatively spliced fragment of the gene Ank3 — encoding the protein ankyrin-G — is present in inhibitory brain neurons but absent in excitatory ones, and controls how electrically active those neurons are. When this microexon was deleted in mice, inhibitory neurons fired more and had elevated calcium signaling, without disrupting the main known function of ankyrin-G at the axon. This shows that small RNA splicing differences can tune neuron-type-specific behavior and may have implications for bipolar disorder, in which Ank3 is a major risk gene.

Plain English
This commentary reviews the current state and risks of AI tools entering neurosurgery in the United States, including FDA-approved tools for tumor detection and surgical navigation. While AI shows real accuracy gains, the authors flag concerns about opaque decision-making, liability gaps, unequal access in rural areas, and the risk of eroding surgical skill. They call for transparent validation, clinician oversight, required AI training, and national adverse-event reporting before broader adoption.

Plain English
This systematic review evaluated how AI and machine learning are being applied across cardiovascular medicine, including echocardiography, ECG analysis, CT angiography, and disease prediction. AI systems consistently matched or outperformed traditional methods in diagnostic accuracy and earlier disease detection. The review highlights that real-world adoption still faces barriers including data quality, model generalizability, ethical concerns, and the need for clear clinical guidelines.

Plain English
This article reviews how neurosurgery training was disrupted by the COVID-19 pandemic — reduced case volumes, limited OR access, and redeployment — and what programs did to adapt. Simulation with low-cost models, virtual dissections, video conferencing, and mentorship networks helped maintain skill development when hands-on cases were scarce. The authors recommend building a permanent flexible training framework that combines case tracking, simulation, video review, and structured mentorship to modernize residency education.

Plain English
This narrative review covers the brain science of lucid dreaming — the state of being consciously aware during a dream — and its possible therapeutic uses. During lucid dreams, the prefrontal and parietal cortex become more active, gamma brain waves increase, and the cholinergic system plays a key role; these same mechanisms may underlie benefits seen in patients with PTSD, chronic nightmares, and Parkinson's disease. The authors conclude that while early evidence is promising, larger controlled trials with standardized methods are needed before lucid dreaming can be recommended as a clinical therapy.

Plain English
This narrative review synthesizes research on stem cell therapies for neurodegenerative diseases including Parkinson's, Alzheimer's, ALS, and Huntington's. Different stem cell types — including mesenchymal and induced pluripotent stem cells — show potential to replace lost neurons, reduce inflammation, and cross the blood-brain barrier via exosomes. Clinical translation remains limited by risks like tumor formation and immune rejection, and the authors conclude that longer studies, standardized protocols, and genetic modification advances are needed before these therapies are ready for routine use.

Plain English
This commentary critically assesses the evidence behind AI tools being used during neurosurgery for navigation, instrument tracking, and imaging analysis. Most supporting studies are small, single-center, and poorly generalizable, with rare external validation and almost no data on whether AI actually improves patient outcomes. The authors argue that progress requires shared datasets, standardized reporting, and multicenter trials before intraoperative AI can be responsibly adopted.

Plain English
Researchers tested whether colchicine — an anti-inflammatory drug — could improve metabolic health in obese mice by suppressing the NLRP3 inflammasome. Colchicine reduced body weight and systemic inflammation but did not affect liver inflammasome markers and, in male mice, actually worsened insulin sensitivity. The dose used is not suitable for metabolic research, and the findings caution against assuming anti-inflammatory benefits will translate to metabolic improvement.

Plain English
This study used an MRI-guided radiation technique called PULSAR to re-treat 45 patients whose grade 4 brain tumors had come back after prior radiation. Radiation was delivered in spaced-out high-dose pulses, allowing MRI scans between sessions to adjust the plan — 80% of patients received at least one such adjustment. Outcomes were poor overall (median survival under 7 months), but adding bevacizumab reduced severe brain swelling by two-thirds, and the study shows the adaptive approach is feasible, even if its benefit over standard re-irradiation remains unproven.

Plain English
This review examined whether AI and deep learning can identify dental implant brands from panoramic X-ray images, which is clinically important for treatment planning when patients don't have implant records. AI models using convolutional neural networks showed strong performance at distinguishing brands after image preprocessing and feature extraction steps. The main barriers to clinical adoption are the need for large labeled training datasets, data privacy concerns, and the difficulty of interpreting AI decisions.

Plain English
This study tested whether a cognitive training technique that teaches people to interpret ambiguous situations as non-threatening could reduce anger in trauma-exposed smokers. The treatment only worked for participants who also had high PTSD symptoms — those individuals showed significantly less trait anger after training, and the effect was explained by actual reductions in their tendency to read hostility into neutral situations. The results suggest this approach should be prioritized for people with both anger problems and PTSD, though the smoking-specific sample limits how broadly the findings apply.

Plain English
A 52-week open-label trial followed schizophrenia patients who had completed short-term studies of xanomeline/trospium — a new antipsychotic that targets muscarinic receptors rather than dopamine. Side effects were mostly mild gastrointestinal symptoms that resolved over time, with no weight gain, metabolic changes, or movement problems that commonly occur with other antipsychotics. Symptom improvements seen in the acute trials were sustained over the full year, supporting this drug as a safe long-term option.

Plain English
Researchers analyzed blood clots retrieved from stroke patients during thrombectomy procedures and found that clots with more neutrophil extracellular traps (NETs) — a type of immune cell debris — were harder to remove in a single pass. Critically, specific features visible on pre-procedure CT scans correlated with high NET content in the clot, suggesting it may be possible to predict clot composition non-invasively before the procedure starts. Knowing clot NET levels in advance could help doctors plan the best mechanical approach for each patient.

Plain English
A large genetic study of over 2,300 cholangiocarcinoma (bile duct cancer) patients identified new inherited genetic variants — particularly in the HLA immune gene region — that increase disease risk. Subtype-specific variants were found for extrahepatic cancer and for cancers linked to the inflammatory bile duct disease PSC. The findings advance understanding of why some people are more susceptible to this rare cancer and may eventually support genetic-based screening or prevention.

Plain English
This case series reported five kidney biopsy procedures that used a new electrocautery device called SinglePass Kronos to seal the biopsy tract immediately after tissue sampling. All five cases were complication-free at 30 days, with imaging confirming no post-biopsy bleeding in any patient. The device shows promise for reducing the most common serious complication of kidney biopsy — bleeding — especially in high-risk patients, though larger studies are needed.

Plain English
A digital intervention aimed at reducing appearance-related anxiety was tested in 203 women, and researchers found that loneliness predicted how well the treatment worked. At low loneliness levels, the appearance-focused treatment beat the control at reducing social anxiety, but this advantage disappeared in lonelier participants. Loneliness before treatment also predicted worse outcomes on social anxiety, eating concerns, and depression at follow-up — suggesting that loneliness is a meaningful barrier to digital mental health treatment effectiveness.

Plain English
An international panel of aesthetic medicine experts developed guidelines for injecting a combination filler product that mixes hyaluronic acid with calcium hydroxyapatite particles to improve skin laxity and stimulate collagen. Key recommendations include using a cannula rather than a needle, targeting the lateral face near bony landmarks, injecting small volumes, and retreating only when laxity returns. The guidelines provide practical standardization for a product with limited prior formal guidance.

Plain English
Using a national surgery database of over 45,000 ankle fracture operations, researchers compared 30-day complication rates between patients treated as inpatients versus outpatients. Inpatients had a complication rate more than twice that of outpatients (6.1% vs 2.6%), but they also had more severe fractures and more medical comorbidities. After accounting for fracture type and health status, age, heart failure, and dependent function status were the strongest independent predictors of complications — factors that should guide surgical planning regardless of treatment setting.

Plain English
This systematic review examined how well UK healthcare workers understood and followed COVID-19 infection control guidelines during the pandemic. Knowledge of specific procedures — like donning and doffing protective equipment correctly — was inconsistent and sometimes poor, while attitude gaps emerged around guidelines that felt irrelevant to specific clinical settings. The review concludes that clearer, setting-specific guidance and better communication of the evidence behind recommendations would improve compliance and reduce hospital-acquired infections.

Plain English
A systematic review and meta-analysis of 26 studies examined whether directly manipulating safety behaviors — the things people do to avoid anxiety or feared outcomes — changes symptoms. Reducing safety behaviors produced meaningful symptom improvements across disorders (effect size d=0.43), while deliberately increasing them worsened symptoms (d=0.65). This confirms that safety behavior change is an active ingredient in anxiety treatment and supports its use as a standalone therapeutic technique.

Plain English
A qualitative study used focus groups with pharmacists, physicians, patients, and other staff to identify what would get in the way of — and what would help — running a research project on pharmacist-led medication reviews in memory clinics. The main barriers were communication gaps, unclear team roles, patient burden, and limited resources, while perceived impact of medication reviews and patient involvement were key facilitators. The findings point to specific policy needs: defined interdisciplinary roles, standardized training, digital tools to reduce burden, and institutional support to make this research feasible.

Plain English
UK surveillance data from nearly 5,000 invasive pneumococcal disease cases were used to model how much disease a new 21-valent adult pneumococcal vaccine (aPCV21) could prevent beyond current vaccines. aPCV21 covers the serotypes responsible for about 82% of cases in adults, including 35% of cases caused by strains not covered by the current childhood vaccine. The vaccine has high potential impact across all adult age groups and could substantially reduce pneumococcal disease burden if deployed in adult vaccination programs.

Plain English
This study tracked immune responses in 47 cancer patients receiving chemotherapy versus 20 healthy people for one year after COVID-19 vaccination. Cancer patients initially had weaker antibody responses but caught up to healthy individuals by six months, and T-cell responses were similar throughout. Despite higher COVID risk scores, cancer patients had no more infections or hospitalizations than healthy individuals — suggesting that COVID-19 vaccines provide meaningful and durable protection even during active chemotherapy.

Plain English
A Kenyan hospital reviewed outcomes in 67 multiple sclerosis patients treated with the B-cell-depleting drugs ocrelizumab or rituximab. Annual relapse rates dropped sharply — the number of patients experiencing relapses fell from 48 to 7 — and MRI showed stable disease in most patients. No serious adverse events occurred, providing real-world evidence that these drugs are safe and effective for MS patients in sub-Saharan Africa, where data have been scarce.

Plain English
Researchers performed comprehensive molecular profiling of myeloid sarcoma — a rare form of leukemia that grows outside the bone marrow — to understand how it develops and find potential treatments. The tumors evolved from standard leukemia through distinct genetic changes and showed immune evasion signatures; RAS pathway mutations were a consistent hallmark. Blocking the RAS pathway in mouse models effectively shrank tumors, identifying RAS inhibition as a promising treatment strategy for this neglected and aggressive disease.
