Abstract Objectives To systematically evaluate the certainty of evidence for treatment strategies across age groups and mood phases in bipolar disorder, and develop an open access web platform to facilitate shared decision making. Design Living umbrella review, evaluation, analysis, and communication hub (U-REACH) project. Data sources PubMed, PsycInfo, and Cochrane library databases, from inception to 19 November 2024. Eligibility criteria for selecting studies Systematic reviews with network or pairwise meta-analyses of randomised controlled trials of pharmacological, nutraceutical, psychosocial, brain stimulation, or circadian rhythm based treatments, administered as monotherapy (without concurrent interventions), augmentation treatment (interventions added to an ongoing treatment regimen), or combination treatment (simultaneous initiation of two different interventions), examining any age group, bipolar disorder phase (ie, acute bipolar depression, mania or mixed episodes, or maintenance), treatment, control, or outcome. Results 77 studies met the inclusion criteria (21 network meta-analyses and 56 pairwise meta-analyses), including 116 unique pharmacological (n=74), brain stimulation (n=18), nutraceutical (n=13), psychosocial (n=8), and circadian rhythm based (n=3) treatments as monotherapy, augmentation, or combination therapy, along with five control interventions. These studies covered 133 unique outcomes (45 efficacy outcomes and 88 safety outcomes) resulting in 2510 meta-analyses with Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) ratings of the certainty of the evidence as high (n=236), moderate (n=827), low (n=986), and very low (n=461). A communication hub, the Evidence Based Interventions for Bipolar Disorder (EBI-BD) platform, was developed and the full results are freely available ( https://ebibd-database.org ), including the preference based tool (12 interventions and 17 safety outcomes). Interventions effective across outcomes varied by phases. For bipolar depression, effective interventions in adults were cariprazine, divalproex or valproate, fluoxetine, ketamine (augmentation), lamotrigine, lumateperone, lurasidone, olanzapine, olanzapine with fluoxetine, and quetiapine, whereas effective interventions in children and adolescents were lurasidone and olanzapine with fluoxetine. For mania episodes, effective interventions in adults were aripiprazole, asenapine, carbamazepine, cariprazine, divalproex or valproate, haloperidol, lithium, olanzapine, paliperidone, quetiapine (also augmentation), risperidone (also as augmentation), tamoxifen, and ziprasidone, whereas effective interventions in children and adolescents were aripiprazole, asenapine, olanzapine, quetiapine, and risperidone. For maintenance, interventions effective across outcomes in adults were aripiprazole (also the long acting injectable formulation), asenapine, divalproex or valproate, lithium, olanzapine, group psychoeducation (augmentation), quetiapine, and risperidone long acting injectable formulation. Interventions effective across phases were aripiprazole (also as augmentation and as a long acting injectable formulation), asenapine, cariprazine, cognitive behavioural therapy (augmentation), divalproex or valproate, lamotrigine, lithium, olanzapine (also as augmentation), paliperidone, quetiapine (also as augmentation), and risperidone (also as augmentation and the long acting injectable formulation) (adults). Treatment effects by neuroscience based nomenclature classes are also reported. Conclusions The EBI-BD tool can help clinicians make evidence based, personalised treatment decisions for bipolar disorder. This resource can inform clinical guidelines and provides a foundation for continuously improving bipolar disorder care as new evidence emerges. Trial registration Open Science Framework https://osf.io/pjmvn/ Readers’ note This is a living systematic review and may be updated in the next two years if additional evidence emerges.

ABSTRACT Background Higher time in sedentary behavior and insufficient physical activity are very common in bipolar disorder (BD). Whereas physical activity and exercise offer significant benefits across mental health, brain health, and heart health in BD. The International Society for Bipolar Disorders Nutrition and Exercise Task Force (NExT) synthesized evidence to evaluate the impacts of sedentary behavior, physical activity, and exercise on illness course, physical health, and treatment outcomes. Methods A best‐evidence synthesis was conducted using a question‐and‐answer format. We searched PsycINFO, SPORTDiscus, Embase, PubMed, and Web of Science from inception to March 1st, 2026, supplemented by reference lists and existing guidelines. Search terms included combinations of physical activity, exercise, sedentary behavior, and bipolar disorder‐related terms. Results Observational studies show that individuals with BD exhibit significantly higher sedentary behavior and lower physical activity compared to the general population, with notable discrepancies between self‐reported and objective measurements. Evidence on physical activity's protective role against BD onset is mixed, with some prospective and Mendelian randomization studies suggesting reduced risk, while others report bidirectional or null associations. Preliminary findings from clinical trials indicate that exercise improves overall functioning, reduces mood episode frequency and hospitalizations, and alleviates depressive symptoms, with one pilot study showing an 82% antidepressant response rate. Exercise also shows potential to reduce anxiety and improve sleep, though robust data are limited. Conclusions Despite limited high‐quality evidence, physical activity and exercise demonstrate promising physical and mental health benefits for individuals with BD. Future research should prioritize multicenter randomized controlled trials, enhanced assessment tools, and accessible, tailored programs to integrate physical activity into routine BD management.

Context.— One objective of the College of American Pathologists/American College of Medical Genetics Cytogenetics Committee is to ensure the accurate detection and clinical interpretation of abnormalities observed by fluorescence in situ hybridization (FISH) analysis when evaluating hematologic neoplasms. Objective.— To report a 20-year performance summary (2005–2024) of FISH challenges focusing on hematologic neoplasms. Design.— A retrospective review was performed from 2005 through 2024 to identify FISH challenges specifically addressing hematologic neoplasms. The overall performance of participants was evaluated to identify potential recurring errors of clinical relevance. Results.— A total of 124 hematologic neoplasm FISH challenges from 2005 to 2024 were provided to participating laboratories, including 45 paper challenges (results and/or images were provided for interpretation purposes), 43 liquid challenges (bone marrow aspirate or peripheral blood), and 36 formalin-fixed paraffin-embedded (FFPE) tissue challenges. Of the 124 challenges, 120 (97%) exceeded the required 80% consensus for grading purposes. Of the 4 failed challenges (3%), 2 (1 liquid, 1 paper) involved the interpretation of atypical FISH signal patterns; 1 (paper) involved the interpretation of FISH signal patterns correlating involvement by myeloid versus lymphoid interphase nuclei; and 1 (liquid) likely involved a specimen processing or handling error that resulted in discordant participant responses. All 36 FFPE tissue challenges exceeded the 80% consensus for grading purposes. Conclusions.— This 20-year retrospective review demonstrates that clinical cytogenomic laboratories have been and continue to be highly proficient in the detection and interpretation of FISH abnormalities associated with hematologic neoplasms.

Abstract Aims This study aimed to identify clinical factors associated with AVC in individuals with T2D. Methods and results This cross-sectional study is a pre-specified substudy of the multicentre randomized Steno INTEN-CT trial (Clinical Trials—INTEN-CT). Participants were eligible if they had T2D without ischaemic heart disease and were aged between 55–69 years (men) or 60–74 years (women). All participants underwent non-contrast cardiac computed tomography. AVC was measured in Agatston Units and categorized as 0, 0–300, ≥ 300. Of the 4570 participants, 46% had AVC > 0. With increasing AVC, patients were older, predominantly males, and with significantly more comorbidities. In multivariable ordered logistic regression age (OR per SD 1.54, 95% CI 1.43–1.66), BMI (OR per SD 1.18, 95% CI 1.11–1.25), hypertension (OR 1.21, 95% CI 1.05–1.40), and chronic kidney disease (OR 1.18, 95% CI 1.03–1.36) were associated with higher AVC. Statin use was also associated with higher AVC (OR 1.50, 95% CI 1.27–1.78). Higher LDL cholesterol showed stronger associations with AVC in men than women (OR 1.39, 95% CI 1.24–1.56 vs. OR 1.16, 95% CI 1.02–1.31, P for interaction = 0.025). T2D severity (Haemoglobin A1c, T2D duration, and number of antidiabetic drugs) was not associated with AVC. Conclusion In individuals with T2D without cardiovascular disease, AVC is prevalent in nearly half of all individuals. Higher AVC was associated with T2D-related comorbidities, but not T2D severity.

ABSTRACT Background Sunlight has profound impacts on physical and mental health, beyond vision, including effects on circadian rhythms, alertness, mood, and sleep. A family history of any mood disorders is strongly associated with psychiatric disorders including bipolar disorder. The purpose of this study was to evaluate the association between a family history of any mood disorder in patients with bipolar I disorder and solar insolation at varied international onset locations. Methods Data for this analysis were available from 5842 patients with a diagnosis of bipolar I disorder obtained at 83 collection sites in both hemispheres. This included 4752 patients from 71 collection sites in the northern hemisphere and 1090 patients from 12 collection sites in the southern hemisphere. Patient data variables were obtained from records or interviews. Solar insolation data were obtained from The National Aeronautics and Space Administration (NASA) Power database for each onset location, and the ratio of the mean monthly minimum/mean monthly maximum solar insolation was calculated. Typically, the ratio is largest near the equator (little yearly change in solar insolation) and smallest near the poles (large yearly change in solar insolation). Results A significant relationship was found between a family history of any mood disorder, the ratio of the mean monthly minimum/mean monthly maximum solar insolation, and gender. The odds of a family history of mood disorder increased as patient location nears the poles and decreased near the equator. Female gender also increased the odds of having a family history of a mood disorder. Conclusions This study highlighted the association between family history, solar insolation, and gender in international patients with bipolar I disorder. Given the profound effects of sunlight on human health, the family of patients with bipolar disorder who live in the same location with the same solar insolation, and especially females, may be at increased risk for a mood disorder.

Background: Sexual dimorphism in the facial skeleton is fundamental to aesthetics and gender perception. This study employs AI-assisted three-dimensional (3D) imaging to analyze morphological differences between males and females in the upper, mid, and lower facial regions. Methods: A retrospective analysis was conducted on 280 high-resolution craniofacial CT scans (147 females, 133 males) of adults aged 20 years and older. AI-assisted segmentation and modeling were performed using Materialise Mimics and 3-Matic software. The facial skeleton was divided into upper, mid, and lower regions for detailed morphometric evaluation. Statistical shape modeling (SSM) and heatmaps were used to visualize surface projection differences across age groups. Statistical comparisons were conducted to assess gender-based variation. Results: Significant sexual dimorphism was observed across all facial regions. In the upper face, males had greater interorbital width, frontotemporal brow width, inter-medial canthi distance, and more prominent frontal bossing. In the midface, males exhibited increased width, depth, and vertical height, with the most pronounced differences occurring in middle age. The lower face showed larger mandibular dimensions in males, including bigonial width, ramus height, and a sharper mental angle, while females had a more rounded chin and smoother mandibular contour. Heatmaps confirmed greater surface projection in male skeletons, particularly in the gonial and midfacial regions, with dimorphism decreasing with age. Conclusion: This represents the first large-sample CT study utilizing AI to comprehensively quantify facial skeletal dimorphism. Findings support the importance of gender-specific planning in facial reconstructive and aesthetic procedures.

Abstract Background Studies suggest that sex influences the deposition of tau in the human brain and impacts on the relationship of tau with AD‐related outcomes. The aim of this study is to evaluate the extent to which sex influences PET‐Tau related outcomes and whether this effect is related to specific tau PET tracers. Method We assessed 456 participants from the HEAD study (mean age = 66.07 ± 13.05). All individuals had available Tau‐PET with Flortaucipir and MK6240, Aβ‐PET and a subset had plasma p ‐Tau 217 ( n = 352). We conducted a linear regression analysis between sex and PET Tau to evaluate the direct influence of sex on PET Tau SUVR. Next, we assessed whether sex affected the relationship between Tau PET (in BRAAK I‐II, III‐IV, V‐VI regions) and Aβ‐PET or plasma p ‐Tau 217 by adding an interaction term in the associations. All analyses were corrected by age, clinical classification, and amyloid burden. Result No significant differences were observed between male and female SUVR levels in either Flortaucipir and MK6240 tracers (Figure 1). However, when assessing the relationship between Aβ‐PET and Tau, a statistically significant interaction with sex was seen between MK6240 in BRAAK III‐IV (β = 0.160, p = 0.020 ; Figure 2) and BRAAK V‐VI regions (β = 0.196, p = 0.008; Figure 2), with women having a stronger association. Furthermore, we found an interaction between sex and p ‐tau217 on Tau PET SUVR in BRAAK regions I‐II using MK6240 or Flortaucipir (β = ‐0.184, p = 0.014; β = ‐0.266, p = 0.002; Figure 3) indicating that women present a weaker relationship between p ‐tau217 and Tau PET. Conclusion Our results did not show any differences between men and women in Tau‐PET SUVR uptake across tau tracers. However, we found that sex affected how Aβ‐PET and plasma p ‐tau217 were associated with Tau‐PET uptake. Further studies are needed to elucidate the underpinnings of the link between sex and the association between these biomarkers.

Context.— Optical genome mapping (OGM) represents a promising cytogenomic technology that detects structural variants, including fusions, rearrangements, copy number variants, and loss of heterozygosity, in a single assay. Unlike karyotyping, fluorescence in situ hybridization, or chromosomal microarray, OGM leverages long-molecule imaging to map the whole genome with high resolution. This positions OGM as a novel tool for constitutional and somatic/cancer genomics. However, its current and planned utilization in clinical and research settings remains unknown, necessitating further investigation. Objective.— To investigate the current utilization of OGM in clinical and research laboratories, assess its applications, and evaluate future utilization strategies. Design.— In 2024, a supplemental questionnaire was incorporated into 6 College of American Pathologists proficiency testing programs to evaluate OGM’s utilization. Results.— Of 921 returned questionnaires, 712 were analyzed after duplicates were removed. Sixty-seven (9.4%) currently offered OGM testing: 5.2% (37) for research only, 1.8% (13) for only clinical use, and 2.4% (17) for both. Future adoption plans showed 7.6% (53 of 700 laboratories) and 7.9% (55 of 700 laboratories) aiming to implement OGM clinically within 12 and 24 months, respectively. The most common applications included hematologic malignancies and constitutional/germline postnatal disorders, followed by prenatal testing. International laboratories demonstrated statistically higher utilization rates than domestic laboratories ( P = .001). Conclusions.— This first survey on OGM clinical utilization reveals its status as a niche technology, with 67 laboratories currently using it. Its primary clinical applications are in constitutional/germline analysis and hematologic malignancies. Although international laboratories led in 2024, 108 laboratories (domestic and international) plan clinical adoption within 24 months, signaling OGM’s potential for broader integration.

Objective Inflammatory bowel disease (IBD) is increasingly recognised in the Middle East, but limited regional data hinder a clear understanding of its burden. We aimed to examine trends in IBD diagnoses, disease phenotypes and predictors of poor outcomes at a major tertiary referral centre in the United Arab Emirates (UAE). Methods In this retrospective observational study, we evaluated diagnostic trends in a cohort of 600 Arab patients between 2002 and June 2025 and analysed detailed phenotypes in a subcohort of 414 patients diagnosed since 2012. Results We observed a nearly 13-fold increase in new IBD diagnoses among Arab patients at our centre between 2002 and 2024. This cohort (median age at diagnosis 25 years; 65% Crohn’s disease (CD; n=269), 35% ulcerative colitis (UC; n=145)) demonstrated a sharper rise in CD compared with UC, with CD being diagnosed at a significantly younger age (median 25 years vs 30 years, p=0.001). A substantial proportion of patients with CD presented with complicated disease defined as stricturing (B2; 22%, n=59), penetrating (B3; 17%, n=46) and perianal (34%, n=92) disease. Ileocolonic (L3) disease was a significant predictor for presenting with a complicated phenotype (OR 3.89). Penetrating (OR 13.9), stricturing (OR 3.38) and perianal (OR 2.22) disease were significant predictors for requiring surgery. 84% of patients with CD and 62% of patients with UC were exposed to advanced therapy. A diagnosis of CD and younger age at diagnosis were associated with a higher likelihood of needing advanced therapy. Conclusions This study provides the most comprehensive data set on IBD diagnoses and phenotypes in the UAE to date, highlighting a pronounced rise in IBD overall and of aggressive disease presentations in CD in particular.

Background: Kienböck disease most frequently affects 1 wrist and rarely occurs bilaterally. The purpose of this study is to describe the natural history and identify risk factors for development of bilateral Kienböck disease. Methods: After institutional review board approval, 350 patients with surgically managed Kienböck disease from 1976 to 2023 were identified. A retrospective review of the electronic medical record was used to collect demographic, clinical, and radiographic information. Two-tailed student t -test was used for continuous variable, and Fisher’s exact test was used for categorical variables with analysis of power. Results: Ten of 350 patients (2.9%) had bilateral disease. The mean age was 45 (range: 14-62) years, and 6 out of 10 patients were female. The mean follow-up time was 47 (range: 9-274) months. Three of the 10 patients were laborers. Antecedent trauma (n = 2), prior corticosteroid injection (n = 1), and concomitant autoimmune disease (n = 1) were rare events. There was no difference in Lichtman Stage comparing the dominant and nondominant hands, and 72.2% of wrists were ulnar negative. This was higher but not significantly different than the unilateral affected comparison cohort (60%). Sufficient power was demonstrated (0.99). Eighteen of 20 wrists were treated operatively. Two cases required operative revision due to progression of disease. Conclusions: The cause of bilateral versus unilateral Kienböck disease remains unclear. Bilateral disease was not associated with a higher incidence of autoimmune disease, systemic corticosteroid use, or exposure to heavy manual labor. However, thrombosis leading to avascular necrosis of the lunate may be influenced by hypercoagulable and inflammatory diseases. Surgeons should maintain a high index of suspicion for bilateral disease in patients with these comorbidities. Routine screening of the contralateral wrist is unjustified if the patient is asymptomatic.
