  • Familist incentives are argued for deceased organ donation in Islamic regions

    What the study found

    The essay argues that a familist incentive approach should be adopted to promote deceased organ donation in Islamic regions. In this approach, immediate relatives of a deceased donor are given priority in organ allocation among medically similar patients.

    Why the authors say this matters

    The authors conclude that the approach could be morally defensible and practically effective in these regions. They also say it could help optimize deceased organ donations, protect the progeny of the family, and improve overall healthcare outcomes.

    What the researchers tested

    This is an essay that presents arguments for adopting a familist incentive approach in Islamic regions. It discusses Islamic moral culture, the value placed on preserving human life, and the priority given to saving family members in the Islamic classics.

    What worked and what didn't

    The essay argues that the familist incentive aligns with Islamic moral culture and the values described in the Islamic classics. It also says practical reasons are offered to address objections to adopting the approach in Islamic regions.

    What to keep in mind

    The abstract does not describe empirical testing or study data. The available summary presents arguments and conclusions, but it does not provide detailed evidence, outcomes, or limitations.

  • Romanian intensivists report communication and system barriers to organ donation

    What the study found

    The survey found that Romanian intensive care physicians generally agreed with brain death diagnostic criteria, but many reported insufficient communication skills and uneven support for organ donation in their hospitals. The authors identified educational, organizational, and system-level barriers to organ donation performance.

    Why the authors say this matters

    The authors conclude that targeted training, better communication strategies, routine integration of donation pathways into intensive care practice, and national consent instruments are important priorities for low-performing transplant systems.

    What the researchers tested

    The researchers conducted a prospective, nationwide, questionnaire-based survey of intensive care physicians in Romania. The questionnaire covered knowledge and attitudes about brain death, communication with families, involvement in donation processes, ethical views, and opinions on transplant-system organization, and the responses were analyzed descriptively.

    What worked and what didn't

    Among 117 ICU physicians, 84.6% agreed with the current brain death diagnostic criteria and 83% said the protocol was sufficiently clear. However, 69.3% said communication competencies were insufficient, 77.8% viewed family consent as decisive, and organ procurement was a priority in only 38.5% of ICUs; structured training and institutional prioritization were inconsistent.

    What to keep in mind

    The study used self-reported survey data from 117 physicians, so it reflects reported perceptions and practices rather than direct observation. The abstract does not describe patient outcomes or provide limitations beyond the survey design and reported scope.

    • Most respondents agreed with brain death diagnostic criteria and found the protocol clear.
    • Many intensivists reported insufficient communication competencies for discussions with families.
    • Family consent was widely seen as decisive in donation decisions.
    • Organ procurement was a priority in only a minority of ICUs.
    • The authors describe educational, organizational, and systemic barriers to organ donation performance.
  • Periodontitis is associated with higher acute myocardial infarction risk

    What the study found

    The review found that periodontitis was associated with a higher risk of acute myocardial infarction (AMI, a heart attack). The association appeared stronger for several measures of periodontal disease severity, including bleeding on probing, clinical attachment loss, probing depth, radiographic bone loss, and remaining bone height.

    Why the authors say this matters

    The authors conclude that these findings highlight the importance of integrated prevention strategies for oral and cardiovascular health. They also say prospective clinical trials are needed to confirm causality.

    What the researchers tested

    The researchers conducted a systematic review and meta-analysis following PRISMA guidelines. They searched PubMed, Embase, Web of Science, and the Cochrane Library through September 25, 2025, and included observational studies on periodontitis and AMI.

    What worked and what didn't

    Seventeen studies with 146,001 participants and 3,199 AMI cases were included. The pooled estimate showed a significantly increased AMI risk in people with periodontitis (OR = 1.84, 95% CI 1.51–2.23), and sensitivity analyses supported the result; publication bias was detected, but trim-and-fill analysis still showed a consistent association (adjusted OR = 1.26, 95% CI 1.03–1.55).

    What to keep in mind

    The available summary describes observational studies, so it cannot establish cause and effect. The meta-analysis also reported substantial heterogeneity (I² = 83.3%) and publication bias, although adjusted analyses remained consistent.

    • Periodontitis was associated with a higher risk of acute myocardial infarction.
    • The pooled odds ratio for AMI was 1.84 in people with periodontitis.
    • Several periodontal severity measures were also associated with AMI risk, including BOP, CAL, PD, RBL, and RBH.
    • Sensitivity analyses supported the main finding.
    • Publication bias was detected, but trim-and-fill analysis still showed an association.
  • Psychosocial factors remain central in lung transplant evaluation

    What the study found

    The review finds that psychosocial factors are linked to outcomes before and after lung transplantation. It also reports that recent lung transplant guidance emphasizes an individualized, holistic evaluation rather than treating most psychosocial issues as absolute reasons not to transplant.

    Why the authors say this matters

    The authors conclude that updated, lung-specific evidence is needed because current recommendations still rely heavily on small single-center studies or information borrowed from other organ transplants. They suggest this matters for improving how psychosocial risk is assessed in lung transplant candidates.

    What the researchers tested

    This article is a review of prior guidelines and newer lung-specific studies on psychosocial challenges in transplantation. The authors synthesized the 2021 International Society for Heart and Lung Transplantation consensus statement, recent evidence, and identified research gaps.

    What worked and what didn't

    The review says emerging lung-specific evidence supports continuing individualized psychosocial risk assessment. It also notes that broad contraindications are not strongly supported, while study findings remain inconsistent because of single-center designs, variable measurement tools, and mixed links with outcomes.

    What to keep in mind

    The abstract says much of the evidence base is limited by reliance on single-center lung transplant studies. It also states that psychosocial assessment tools need validation, larger multicenter and international studies are needed, and targeted interventions still need development.

    • Psychosocial factors are associated with pre- and post-transplant outcomes.
    • The 2021 ISHLT consensus statement emphasizes individualized, holistic evaluation.
    • Few psychosocial domains are treated as absolute contraindications in current guidance.
    • Evidence is limited by small single-center studies and inconsistent measurement tools.
    • The authors identify a need for validated lung-specific tools and larger studies.
  • Persistent post-COVID respiratory symptoms linked to dysregulated breathing

    What the study found

    Among non-hospitalised adults referred to a post-COVID respiratory clinic, shortness of breath was common and was often accompanied by dysregulated breathing, reduced physical performance, and frailty. The authors report that dysregulated breathing, deconditioning, and psychological distress were key factors linked with symptom burden.

    Why the authors say this matters

    The authors conclude that a multidisciplinary approach should be considered to optimise recovery. They suggest this because symptoms were associated with breathing pattern changes, physical deconditioning, and psychological distress rather than with common spirometry and chest CT abnormalities.

    What the researchers tested

    The study used a cross-sectional analysis of 210 non-hospitalised adults with persistent respiratory symptoms after COVID-19 who were referred to a post-COVID respiratory clinic between December 2020 and July 2024. Researchers assessed demographics, symptoms, lung function, chest CT, and patient-reported outcome measures, including the Medical Research Council (MRC) dyspnoea score, Nijmegen Questionnaire, Hospital Anxiety and Depression Scale, Chalder Fatigue Scale, Short Physical Performance Battery, and Fried Frailty Index, and they used multivariate logistic regression to examine associations.

    What worked and what didn't

    95% of participants reported shortness of breath, 54% had clinically significant breathlessness, 68% had Nijmegen Questionnaire scores consistent with dysregulated breathing, 32% had low Short Physical Performance Battery scores, and 77% were classed as frail or pre-frail. Higher body mass index and depression were associated with clinically significant breathlessness, while dysregulated breathing was associated with female sex, current or former smoking, fatigue, anxiety, and depression; low physical performance was associated with female sex, current smoking, depression, clinically significant breathlessness, dysregulated breathing, and greater deprivation. Spirometry and chest CT abnormalities were not common, and nearly half of those employed before infection had not returned to previous hours.

    What to keep in mind

    This was a cross-sectional study, so it describes associations rather than cause and effect. The sample came from adults referred to one post-COVID respiratory clinic and included only those who consented to research, so the findings may not apply to all people after COVID-19.

    • In 210 non-hospitalised adults with persistent post-COVID respiratory symptoms, 95% reported shortness of breath.
    • 68% had a Nijmegen Questionnaire score consistent with dysregulated breathing.
    • 32% had low physical performance, and 77% were classed as frail or pre-frail.
    • Higher body mass index and depression were associated with clinically significant breathlessness.
    • Spirometry and chest CT abnormalities were not common in this group.
  • Cardiac biomarkers rise with hypertensive disorders in pregnancy

    What the study found

    Pregnant women with hypertensive disorders had higher levels of several cardiac and tissue injury biomarkers than normotensive pregnant women, and the increases were greatest in preeclampsia. The strongest rise was seen in NT-proBNP, a biomarker of ventricular wall stress.

    Why the authors say this matters

    The authors conclude that these biomarkers may help with risk assessment and clinical monitoring in hypertensive disorders of pregnancy. They also state that integrating specific biomarkers into routine screening could support earlier risk stratification and improve maternal-foetal outcomes.

    What the researchers tested

    The researchers conducted a cross-sectional study at a tertiary care hospital in Central India from May 2023 to May 2024. They compared 312 pregnant participants: normotensive women, women with gestational hypertension, and women with preeclampsia, measuring biomarkers including CPK-MB, LDH, SGOT, high-sensitivity C-reactive protein, glucose, creatinine, troponin I, and NT-proBNP.

    What worked and what didn't

    There was no significant difference in age or body mass index among the groups. Levels of NT-proBNP, troponin I, CPK-MB, SGOT, and LDH increased stepwise from normotensive pregnancy to gestational hypertension to preeclampsia, and these differences were reported as significant.

    What to keep in mind

    This was a cross-sectional study, so it measured biomarker levels at one point in time rather than tracking changes over time. The abstract does not describe other limitations.

    • 312 pregnant participants were grouped into normotensive, gestational hypertension, and preeclampsia categories.
    • NT-proBNP rose from 29 pg/mL in normotensive women to 40 pg/mL in gestational hypertension and 155 pg/mL in preeclampsia.
    • Troponin I, CPK-MB, SGOT, and LDH were significantly higher in the hypertensive disorder groups.
    • Age and body mass index did not differ significantly between groups.
    • The authors conclude the biomarkers may support risk assessment and clinical monitoring.
  • Donor factors linked to pancreas transplant use changed over time

    What the study found

    The study found that multiple donor factors were associated with whether a pancreas was used for transplant, and that these decisions changed over time. The most influential continuous factors were age, body mass index (a measure of body fat based on height and weight), and peak creatinine (a kidney function marker).

    Why the authors say this matters

    The authors conclude that the findings show significant shifts in pancreas transplant decision-making over time. They say growing reluctance to use donation after circulatory death (DCD, donation after the heart has stopped) donors is an area to focus U.S. pancreas utilization efforts, while increasing acceptance of hepatitis C positive and intravenous drug use (IVDU) donors may support broader use of these donor groups globally.

    What the researchers tested

    The researchers conducted a population-cohort study using U.S. Organ Procurement and Transplant Network registry data from 2010 to 2024. They used multivariable regression models to test associations between donor characteristics and pancreas utilization, and they used restricted cubic splines to model non-linear relationships plus interaction terms with donation date to examine changes over time.

    What worked and what didn't

    The study identified 23 donor factors significantly associated with pancreas utilization across 133,986 donors and 14,612 transplants. Donation after circulatory death had much lower odds of utilization, with 92% lower odds than the comparison group, while age, body mass index, and peak creatinine showed significant non-linear relationships with utilization. Over time, clinicians became less willing to use DCD donors and older donors, but more willing to use hepatitis C positive and IVDU donors.

    What to keep in mind

    The abstract does not describe study limitations in detail. The data come from U.S. registry records, so the findings directly reflect U.S. practice and the time period studied.

    • Twenty-three donor factors were significantly associated with pancreas utilization.
    • Age, body mass index, and peak creatinine were the most important continuous donor factors.
    • Donation after circulatory death was associated with 92% lower odds of pancreas use.
    • Reluctance to use DCD donors and older donors increased over time.
    • Acceptance of hepatitis C positive and IVDU donors increased over time.
  • Echocardiography showed worsening heart changes with more severe pregnancy hypertension

    What the study found

    Women with hypertensive disorders of pregnancy showed increasing heart-related hemodynamic changes as the condition became more severe. The study also found that these changes were associated with more adverse pregnancy and newborn outcomes.

    Why the authors say this matters

    The authors conclude that two-dimensional echocardiography, an ultrasound test of the heart, can provide useful insight into cardiovascular involvement in hypertensive pregnancy. They also say the findings should be interpreted cautiously because the study was observational and did not include predictive modeling.

    What the researchers tested

    This hospital-based prospective observational study included 70 pregnant women beyond 20 weeks of gestation with hypertensive disorders of pregnancy. The participants were grouped into mild, moderate, and severe categories and underwent comprehensive two-dimensional echocardiographic assessment of systolic and diastolic parameters.

    What worked and what didn't

    Left ventricular end-systolic and end-diastolic volumes and cardiac output increased significantly with disease severity, while total vascular resistance decreased significantly. Diastolic dysfunction was present in 51 women and was more frequent in severe disease, and the E/A ratio declined with increasing severity. Severe disease was also associated with higher rates of preterm delivery, low birth weight, and neonatal intensive care unit admission.

    What to keep in mind

    The study is limited to an observational design, so it cannot establish prediction or causation. The abstract also says larger studies with appropriate comparator groups are needed to clarify the clinical and prognostic significance of these findings.

    • Hypertensive disorders of pregnancy were linked to worsening systolic and diastolic cardiac changes.
    • Left ventricular volumes and cardiac output rose as disease severity increased.
    • Total vascular resistance fell significantly across severity groups.
    • Diastolic dysfunction was found in 51 women and was more common in severe disease.
    • Severe disease was associated with preterm delivery, low birth weight, and NICU admission.
  • XGBoost was the most accurate transplant prediction model

    What the study found

    The study found that among the classifiers tested, XGBoost was the most accurate, reliable, and generalizable model for predicting late estimated glomerular filtration rate, or eGFR, a measure of kidney filtering function. The authors also state that Monte Carlo simulation was a significant methodological advance in kidney transplantation.

    Why the authors say this matters

    The authors conclude that advanced numerical methods for kidney transplant patients' therapy are a step forward in optimizing current immunosuppressive protocols, which are the medicine regimens used to prevent transplant rejection. The study suggests this approach may support better prediction modeling in kidney transplantation.

    What the researchers tested

    The researchers used experimental data from kidney transplantation with a tacrolimus-based immunosuppressive protocol, where tacrolimus is a transplant medicine used to suppress the immune system. They applied Monte Carlo simulation and trained three machine learning classifiers: DecisionTreeClassifier, Random Forest Classifier, and XGBClassifier.

    What worked and what didn't

    XGBoost performed best among the tested classifiers. The abstract does not provide numerical performance values for the models, and it does not describe any specific classifier failures beyond ranking them below XGBoost.

    What to keep in mind

    The summary provided here is limited to the abstract, so details such as sample size, validation design, and performance metrics are not available. The abstract also does not describe study limitations or uncertainty beyond the comparative result reported.

    • XGBoost was reported as the most accurate, reliable, and generalizable classifier.
    • The study used Monte Carlo simulation with kidney transplantation data.
    • The clinical context involved a tacrolimus-based immunosuppressive protocol.
    • The model focused on predicting late estimated glomerular filtration rate, or eGFR.
    • Three classifiers were compared: DecisionTreeClassifier, Random Forest Classifier, and XGBClassifier.
  • MuST AKT was feasible and acceptable in a pilot trial

    What the study found

    The study found that the Multidisciplinary Support To Access living donor Kidney Transplant (MuST AKT) intervention was feasible with minor modifications and acceptable to transplant candidates and their social network. Participants also reported increased confidence in communicating about living donor kidney transplantation, which means receiving a kidney from a living donor.

    Why the authors say this matters

    The authors developed the intervention to increase living donor kidney transplantation, and the study suggests it may help transplant candidates address barriers to that process. The authors conclude that the intervention may be a workable approach for this setting.

    What the researchers tested

    The researchers conducted a pilot randomized controlled trial, which is a small study that randomly assigns participants to compare an intervention with standard care. Transplant candidates were assigned to standard care or MuST AKT, and the intervention involved four 60- to 90-minute sessions in which candidates and their social network addressed barriers to living donor kidney transplantation.

    What worked and what didn't

    The recruitment rate was 61% (43 of 71), and 38 participants were randomized equally between groups. Among intervention participants, one was excluded before starting, and of those who started, 100% completed 1 session, 94% completed 2 sessions, 83% completed 3 sessions, and 56% completed all 4 sessions; the intervention was delivered in a mean of 71 days, shorter than anticipated. Intervention participants reported increased confidence in communicating about living donor kidney transplantation, and all recommended MuST AKT to peers.

    What to keep in mind

    This was a pilot study with a small sample, so the findings are about feasibility and acceptability rather than effectiveness. The abstract also notes that participants and social network invitees gave recommendations for improvement, but it does not provide detailed limitations beyond the need for minor modifications.

    • MuST AKT was found to be feasible with minor modifications.
    • The intervention was acceptable to transplant candidates and their social network.
    • Recruitment reached 61% of eligible candidates, with 38 people randomized.
    • Completion declined across the four sessions, from 100% for session 1 to 56% for session 4.
    • Participants reported increased confidence in communicating about living donor kidney transplantation.
