Safety of psychotropic medications in pregnancy: an umbrella review.

Weighing risks and benefits of the use of psychotropic medications during pregnancy remains a challenge worldwide. We systematically assessed the strength of associations between psychotropic medication use in pregnant people with mental disorders and various adverse health outcomes in both pregnant people and foetuses. Systematic reviews with meta-analyses of observational studies investigating the association between exposure to psychotropic medication in pregnancy and any adverse health outcomes were included. Credibility was graded into convincing, highly suggestive, suggestive, weak or not significant. Quality of the meta-analyses and of individual studies were assessed with A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) the Newcastle-Ottawa Scale (NOS), respectively. We considered 21 meta-analyses encompassing 17,290,755 participants (AMSTAR 2 high = 1, low = 12, or critically low = 8). Evidence was suggestive for: (1) preterm birth in pregnant people with either any mental disorder (equivalent odds ratio 1.62 (95% confidence interval 1.24-2.12) or depression (1.65 [1.34-2.02]) receiving antidepressants during any trimester of pregnancy; (2) small for gestational age for pregnant people with depression receiving a SSRI during any trimester of pregnancy (1.50 [1.19-1.90]); and (3) major congenital malformation (1.24 [1.09-1.40]) or cardiac malformations (1.28 [1.11-1.47]) in babies for pregnant people with depression or anxiety receiving paroxetine during first trimester of pregnancy. Additional associations were supported by weak evidence, or were not statistically significant. This umbrella review found no convincing or highly suggestive level of evidence of adverse health outcomes associated with psychotropic medication use in pregnant people with mental disorders.

The effect of weighted blankets on sleep quality and mental health symptoms in people with psychiatric disorders in inpatient and outpatient settings: A systematic review and meta-analysis.

There is limited synthesized evidence for weighted blankets usage in psychiatric patients. We performed a PRISMA compliant systematic review and meta-analysis of the effects of weighted blankets on sleep and mental health outcomes in psychiatric patients. MEDLINE, EMBASE, Cochrane Library, and PsycINFO were searched up to December 15th, 2023. Randomized controlled trials (RCT) or cohort studies reporting objective outcome scales of sleep and mental health were included. Standardized mean difference (SMD) measured effect size. Q and I2 tests measured heterogeneity. Cochrane Risk of Bias Tool 2 and NIH Quality Assessment Tool assessed risk of bias. Nine studies of 553 psychiatric inpatients and outpatients with diagnoses including depression, bipolar disorder, ADHD, and autism. 289 participants received weighted blankets and 264 were in control groups. Intervention length ranged from 5 min to one year. Four studies reported evidence for weighted blankets in improving insomnia, total sleep time, and sleep onset latency. Six studies reported evidence for reducing anxiety symptoms. When compared to placebo, those using weighted blankets had improvements to anxiety symptoms (SMD = -0.47, 95% CI: -0.68 to -0.25, p < 0.001). One RCT had low risk of bias, 3 had some concerns, 1 was high risk. Three cohort studies were "fair" and one was "poor" in quality. It was found that weighted blankets can be effective in reducing anxiety in psychiatric patients. However, the literature is limited by heterogeneity of outcome reporting, lack of well designed RCTs, and small sample sizes. Highlighting the need for higher quality studies.

No Increased Risk of All-cause Revision up to 10 Years in Patients Who Underwent Bariatric Surgery Before Single-level Lumbar Fusion.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: This study aimed to assess whether prior bariatric surgery (BS) is associated with higher 10-year surgical complication and revision rates in lumbar spine fusion compared with the general population and morbidly obese patients. BACKGROUND: Obesity accelerates degenerative spine processes, often necessitating lumbar fusion for functional improvement. BS is explored for weight loss in lumbar spine cases, but its impact on fusion outcomes remains unclear. Existing literature on BS before lumbar fusion yields conflicting results, with a limited investigation into long-term spine complications. METHODS: Utilizing the PearlDiver database, we examined patients undergoing elective primary single-level lumbar fusion, categorizing them by prior BS. Propensity score matching created cohorts from (1) the general population without BS history and (2) morbidly obese patients without BS history. Using Kaplan-Meier and Cox proportional hazard modeling, we compared 10-year cumulative incidence rates and hazard ratios (HRs) for all-cause revision and specific revision indications. RESULTS: Patients who underwent BS exhibited a higher cumulative incidence and risk of decompressive laminectomy and irrigation & debridement (I&D) within 10 years postlumbar fusion compared with matched controls from the general population [decompressive laminectomy: HR = 1.32; I&D: HR = 1.35]. Compared with matched controls from a morbidly obese population, patients who underwent BS were associated with lower rates of adjacent segment disease (HR = 0.31) and I&D (HR = 0.64). However, the risk of all-cause revision within 10 years did not increase for patients who underwent BS compared with matched or unmatched controls from the general population or morbidly obese patients (P > 0.05). CONCLUSIONS: Prior BS did not elevate the 10-year all-cause revision risk in lumbar fusion compared with the general population or morbidly obese patients. However, patients who underwent BS were associated with a lower 10-year risk of I&D when compared with morbidly obese patients without BS. Our study indicates comparable long-term surgical complication rates between patients who underwent BS and these control groups, with an associated reduction in risk of infectious complications when compared with morbidly obese patients. Although BS may address medical comorbidities, its impact on long-term lumbar fusion revision outcomes is limited.

Effects of antipsychotic treatment on cardio-cerebrovascular related mortality in schizophrenia: A subanalysis of a systematic review and meta-analysis with meta-regression of moderators.

To further explore the role of different antipsychotic treatments for cardio-cerebrovascular mortality, we performed several subgroup, sensitivity and meta-regression analyses based on a large previous meta-analysis focusing on cohort studies assessing mortality relative risk (RR) for cardio-cerebrovascular disorders in people with schizophrenia, comparing antipsychotic treatment versus no antipsychotic. Quality assessment through the Newcastle-Ottawa Scale (NOS) and publication bias was measured. We meta-analyzed 53 different studies (schizophrenia patients: n = 2,513,359; controls: n = 360,504,484) to highlight the differential effects of antipsychotic treatment regimens on cardio-cerebrovascular-related mortality in incident and prevalent samples of patients with schizophrenia. We found first generation antipsychotics (FGA) to be associated with higher mortality in incident samples of schizophrenia (oral FGA [RR=2.20, 95 %CI=1.29-3.77, k = 1] and any FGA [RR=1.70, 95 %CI=1.20-2.41, k = 1]). Conversely, second generation antipsychotics (SGAs) and clozapine were associated with reduced cardio-cerebrovascular-related mortality, in prevalent samples of schizophrenia. Subgroup analyses with NOS score ≥7 (higher quality) demonstrated a significantly increased cardio-cerebrovascular disorder-related mortality, among those exposed to FGAs vs SGAs. Meta-regression analyses demonstrated a larger association between antipsychotics and decreased risk of mortality with longer follow-up, recent study year, and higher number of adjustment variables. Overall, this subanalysis of a systematic review contributes to the evolving understanding of the complex role of antipsychotic treatment for cardio-cerebrovascular mortality in schizophrenia, paving the way for more targeted interventions and improved patient outcomes.

Left atrial reservoir strain is a superior discriminator of cardioembolism in ischaemic stroke.

Aims: Echocardiographic measures of left heart size and function have long been associated with cardioembolic mechanisms of stroke development, however, the diagnostic performance and comparison of measures of atrial function in this context has not been well studied. We sought to evaluate the diagnostic performance of left atrial reservoir strain (LASr) in identification of cardioembolism in the ischaemic stroke population relative to traditional measures of left heart size and function. Methods and results: Consecutive patients admitted to our institution with ischaemic stroke or transient ischaemic attack were recruited and underwent comprehensive transthoracic echocardiography. Strokes were classified by aetiology with comparison undertaken between cardioembolic and non-cardioembolic types. Four hundred and eighteen consecutive stroke patients with a cardioembolic (n = 229) or non-cardioembolic (n = 189) stroke aetiology were analysed. LASr was impaired in cardioembolic compared with non-cardioembolic strokes (16.7 ± 8.2% vs. 26.0 ± 5.5%, P < 0.01) and provided greatest discrimination [area under the curve (AUC) 0.813, 95%CI 0.773-0.858] in differentiating stroke subtypes when compared with LVEF (AUC difference 0.150, P < 0.01), LAVI (AUC difference 0.083, P < 0.01), and E/e' (AUC difference 0.163, P < 0.01). Inclusion of LASr in a model with conventional left heart echocardiographic factors improved model performance with a net reclassification improvement of 1.083 (95%CI 0.945-1.220, P < 0.01). Further, a proposed user-defined model-based clinical algorithm with LASr demonstrated improved diagnostic accuracy of the identification of cardioembolic stroke subtypes which was best appreciated in patients without atrial fibrillation. Conclusion: LASr may provide enhanced diagnostic accuracy beyond conventional echocardiographic measures to discriminate cardioembolic from non-cardioembolic stroke mechanisms, in particular amongst those without comorbid atrial fibrillation.

Sublingual Dermoid in an Adult Patient.

Dermoid cysts in the floor of the mouth are a relatively rare and unusual site of location anomalies presumed to be caused by entrapment of germinal epithelium along the lines of embryonic fusion. It presents as soft, non-painful, and slowly growing swelling along the lines of fusion during the closure of mandibular and hyoid branch arches. These cysts are developmental and histopathologically classified into three types: epidermoid, dermoid, and teratoid. We are reporting a rare case of a 32-year-old female who presented in the outpatient department with complaints of painless swelling over the floor of the mouth for two years, suggesting a benign sublingual mass. This case report underscores the importance of clinical presentation, diagnostic workup, and surgical approach in achieving successful outcomes for sublingual mass.

How to optimize the systematic review process using AI tools.

Systematic reviews are a cornerstone for synthesizing the available evidence on a given topic. They simultaneously allow for gaps in the literature to be identified and provide direction for future research. However, due to the ever-increasing volume and complexity of the available literature, traditional methods for conducting systematic reviews are less efficient and more time-consuming. Numerous artificial intelligence (AI) tools are being released with the potential to optimize efficiency in academic writing and assist with various stages of the systematic review process including developing and refining search strategies, screening titles and abstracts for inclusion or exclusion criteria, extracting essential data from studies and summarizing findings. Therefore, in this article we provide an overview of the currently available tools and how they can be incorporated into the systematic review process to improve efficiency and quality of research synthesis. We emphasize that authors must report all AI tools that have been used at each stage to ensure replicability as part of reporting in methods.

On the value of meta-research for early career researchers: A commentary.

Meta-research, also known as "research on research" is a field of study that investigates the methods, reporting, reproducibility, evaluation, and incentives along the research continuum. Meta-research literacy is imperative to ensure high quality, transparent and reproducible primary data or meta-research products. In this commentary, we propose that early career researchers should be trained in meta-research as a foundation to develop a deeper understanding of the research process and ability to appraise the research literature and design high-quality original studies, irrespective of their chosen field of study. We discuss the importance of meta-research and open science from the perspective of an early career trainee, highlighting essential areas for growth and obstacles one may encounter.

Interventions to prevent and treat delirium: An umbrella review of randomized controlled trials.

Delirium is a common condition across different settings and populations. The interventions for preventing and managing this condition are still poorly known. The aim of this umbrella review is to synthesize and grade all preventative and therapeutic interventions for delirium. We searched five databases from database inception up to March 15th, 2023 and we included meta-analyses of randomized controlled trials (RCTs) to decrease the risk of/the severity of delirium. From 1959 records after deduplication, we included 59 systematic reviews with meta-analyses, providing 110 meta-analytic estimates across populations, interventions, outcomes, settings, and age groups (485 unique RCTs, 172,045 participants). In surgery setting, for preventing delirium, high GRADE evidence supported dexmedetomidine (RR=0.53; 95%CI: 0.46-0.67, k=13, N=3988) and comprehensive geriatric assessment (OR=0.46; 95%CI=0.32-0.67, k=3, N=496) in older adults, dexmedetomidine in adults (RR=0.33, 95%CI=0.24-0.45, k=7, N=1974), A2-adrenergic agonists after induction of anesthesia (OR= 0.28, 95%CI= 0.19-0.40, k=10, N=669) in children. High certainty evidence did not support melatonergic agents in older adults for delirium prevention. Moderate certainty supported the effect of dexmedetomidine in adults and children (k=4), various non-pharmacological interventions in adults and older people (k=4), second-generation antipsychotics in adults and mixed age groups (k=3), EEG-guided anesthesia in adults (k=2), mixed pharmacological interventions (k=1), five other specific pharmacological interventions in children (k=1 each). In conclusion, our work indicates that effective treatments to prevent delirium differ across populations, settings, and age groups. Results inform future guidelines to prevent or treat delirium, accounting for safety and costs of interventions. More research is needed in non-surgical settings.

Mesenchymal stem cell based therapies for uveitis: a systematic review of preclinical studies.

Cell therapy has shown promising results for treating uveitis in preclinical studies. As the field continues to grow towards clinical translation, it is important to review and critically appraise existing studies. Herein, we analysed and critically appraised all preclinical studies using cell therapy or cell derived extracellular vesicles (EVs) for uveitis, and provided insight into mechanisms regulating ocular inflammation. We used PubMed, Medline, and Embase to search for preclinical studies examining stem cell therapy (e.g., mesenchymal stem cells [MSC]) and secreted EVs. All included studies were assessed for quality using the SYstematic Review Center for Laboratory animal Experimentation (SYRCLE) checklist. Sixteen preclinical studies from 2011 to 2022 were analysed and included in this review of which 75% (n = 12) focused only on cell therapy, 18.7% (n = 3) studies focused on EVs, and 6.3% (n = 1) study focused on both cells and EVs. MSCs were the most common type of cells used in preclinical studies (n = 15) and EVs were commonly isolated from MSCs (n = 3). Overall, both MSCs and EVs showed improvements in ocular inflammation (seen on fundoscopy/slit lamp and histology) and electroretinogram outcomes. Overall, MSC and MSC-derived EVs shown great potential as therapeutic agents for treating uveitis. Unfortunately, small sample size, risk of selection/performance bias, and lack of standardized cell harvesting or delivery protocols are some factors which limits clinical translation. Large scaled, randomized preclinical studies are required to understand the full potential of MSCs for treating uveitis.
