Background: Religious affiliation has traditionally served as a coping strategy during stressful events such as the COVID-19 pandemic. Pregnant women faced heightened stress during the pandemic due to concerns about their health as well as that of their fetus. This study examined the prevalence of self-reported religious affiliation among SARS-CoV-2-positive pregnant women and investigated differences in psychiatric diagnoses and pregnancy outcomes based on religious affiliation. Methods: The study included all asymptomatic or mildly symptomatic SARS-CoV-2-positive pregnant women who received care at the Mayo Health System from March 2020 through October 2021 and completed the routine religious affiliation questionnaire. Those selecting “none” were categorized as having no religious affiliation (RA−), whereas those selecting a specific religion were categorized as religiously affiliated (RA+). Results: Among 609 women, 49.6% were RA+ and 50.4% were RA−. RA+ women were more likely to be white, married, college-educated, and have fewer prior abortions. There were no significant differences in rates of depression, anxiety, psychotropic medication use, substance use, or pregnancy and labor complications between RA+ and RA− groups. Conclusions: Half of the women in this cohort reported no religious affiliation. Previously reported protective associations between religiosity and mental health were not observed when religious affiliation alone was examined.

Objective: This study aimed to examine whether parent–child interaction therapy (PCIT), compared with other therapy modalities, was associated with differences in substance use and psychiatric outcomes in a cohort of children with attention-deficit/hyperactivity disorder (ADHD). Methods: This retrospective cohort study was conducted using medical record data from the Rochester Epidemiology Project (REP). The sample included 643 children aged ≤7 years who were diagnosed with ADHD and received either stimulant or nonstimulant medication, along with psychosocial therapy. Participants were categorized into two groups: those who documented exposure to PCIT versus other therapy modalities such as behavioral management, play therapy, cognitive behavioral therapy, parent management training, occupational therapy, speech therapy, parenting class, applied behavior analysis, and social skills training. Conditional logistic regression models were used to examine differences in baseline characteristics and outcomes between the two treatment groups. Results: Individuals in the PCIT group were more likely to have private insurance (66% vs. 57%; p = 0.016) and to fall into higher socioeconomic status quartiles ( p = 0.024) at baseline. PCIT recipients also had a higher prevalence of emotional and behavioral disturbances at baseline (40% vs. 25%; p < 0.001). The median age of the participants at follow-up was 19.6 years, indicating a median follow-up period of approximately 13 years from the initiation of treatment. At follow-up, the PCIT group demonstrated higher rates of problematic alcohol (24% vs. 17%; HR = 1.50, 95% CI: [1.02, 2.20]; p = 0.038) and cannabis use (25% vs. 18%; HR = 1.48, 95% CI: [1.03, 2.15]; p = 0.037). However, after controlling for covariates in the adjusted model, no statistically significant differences emerged between the groups across any substance use outcome. No significant differences were observed in other psychiatric diagnoses or mental health service utilization. Conclusions: Findings indicate that individuals who documented exposure to PCIT demonstrated elevated rates of alcohol and cannabis use in young adulthood, but had no other differences in psychiatric outcomes. While this aligns with prior literature reporting increased substance use risk in ADHD populations, our study cannot confirm this association relative to non-ADHD controls because such a comparison was not included. These associations likely reflect underlying differences in clinical severity and clinical comorbidities at baseline, rather than a direct effect of PCIT. Further investigation is warranted to determine the treatment effects based on baseline risk factors.

ABSTRACT Introduction Sodium‐glucose cotransporter‐2 inhibitors (SGLT2i), initially developed for type 2 diabetes, have shown promise in improving renal outcomes in patients with and without diabetes. However, their effect on lithium‐associated kidney dysfunction remains unknown. Methods This historical cohort study included patients from Mayo Clinic (2001–2023) with mood disorders who received lithium for ≥ 6 months and later used SGLT2i for ≥ 1 month. Data on SGLT2i use and lithium treatment were extracted from electronic health records. Serum creatinine values were used to calculate estimated glomerular filtration rate (eGFR) trajectories. Linear mixed‐effects models with piecewise linear splines were used to estimate eGFR slopes before and after SGLT2i initiation, adjusted for age and sex. Results Fifty‐six patients (mean age 57.4 years, 46.4% female), predominantly with bipolar disorder (87.5%), were included. The mean eGFR, measured nearest to SGLT2i initiation, was 77.9 ± 26.0 mL/min/1.73 m 2 , and the mean duration of SGLT2i use was 19.5 ± 17.8 months. Before SGLT2i initiation, eGFR declined at a rate of −1.43 mL/min/1.73 m 2 per year ( p < 0.001). After initiation, eGFR increased by 0.69 mL/min/1.73 m 2 per year, reflecting a + 2.13 change ( p = 0.025). Sensitivity analyses, including only patients on lithium at SGLT2i initiation ( n = 22) or who had > 1 year of SGLT2i use ( n = 29) showed similar, though non‐significant, changes in slopes. Conclusion SGLT2i treatment was associated with a significant improvement in eGFR trajectory in patients with mood disorders who received long‐term lithium therapy. These findings suggest a potential role for SGLT2is in mitigating lithium‐associated kidney dysfunction and highlight the need for randomized controlled trials in this population.

Background: Bipolar disorder (BD) is associated with a higher prevalence of chronic kidney disease (CKD) and increased mortality, yet individuals with both BD and CKD are less likely to receive kidney replacement therapy (KRT). Sodium-glucose cotransporter-2 inhibitors (SGLT2is) provide renal protection in diabetes, but their long-term effects in this high-risk population remain unknown. Objectives: To evaluate whether SGLT2i use reduces the risk of KRT and all-cause mortality in adults with BD and mild-to-moderate CKD (stage ⩽ 3). Design: Observational cohort study with propensity score matching (PSM). Method: In this study using TriNetX (2009–2024) real-world database, 89,369 adults with BD and mild-to-moderate CKD were classified as SGLT2i users ( n = 12,736) or nonusers ( n = 76,633). Primary outcomes were progression to KRT and all-cause mortality over 5 years. Adjusted hazard ratios (aHRs) were estimated using Cox proportional hazards models, and 1:1 PSM reduced confounding. Subgroup analyses examined sex, race/ethnicity, diabetes status, CKD stage, and mood stabilizer use. Results: SGLT2i use was associated with lower risk of KRT (aHR 0.47 (95% CI, 0.42–0.53)) and all-cause mortality (aHR 0.69 (95% CI, 0.65–0.73); both p < 0.001). Protective effects were consistent across subgroups, including individuals receiving lithium, lamotrigine, valproate, or antipsychotics. After PSM (10,967 matched pairs), 5-year KRT-free survival was 94.61% versus 90.99%, and overall survival was 78.67% versus 67.53% (both p < 0.001). Given the observational design, the possibility of residual or unmeasured confounding canot be excluded. Conclusion: SGLT2i therapy in individuals with BD and mild-to-moderate CKD is associated with substantially lower risks of KRT and all-cause mortality. Prospective trials are needed to confirm these findings.

Background: Lithium, the gold standard treatment of bipolar disorder (BD), is thought to cause nephropathy in long-term users. However, the role of confounding variables linked to BD in exerting this adverse effect remains unclear. Objectives: This paper evaluates kidney function in patients with affective disorders who are taking lithium compared to patients not on lithium treatment. Design: This article is a systematic review and meta-analysis. Data sources and methods: A comprehensive search of publications up to October 2023 within Cochrane, Embase, PubMed, Scopus, Web of Science, and CINAHL databases was performed. Three assessors screened and extracted data from eligible observational studies. Risk of bias assessment was done with the ROBINS-E tool. Eligible studies were comparative studies of adult patients with diagnoses of affective disorders, including BD on lithium, with control groups not on lithium, reporting kidney function outcomes. Results: Mean estimated Glomerular filtration rate (eGFR) showed less favorable outcomes in the lithium group compared to the non-lithium group ( n = 1622, MD = −11.14 ml/min/1.73 m 2 , 95% CI: −16.61, −5.68, I 2 = 86%). The mean annual eGFR decline comparison favored the non-lithium group ( n = 13,280, MD = 0.13 ml/min/1.73 m 2 , 95% CI: 0.06, 0.20, I 2 = 0%). Serum creatinine concentration (mg/dl) was found to be higher in the lithium compared to non-lithium groups ( n = = 1704, MD = 0.05, 95% CI: 0.03, 0.07, I 2 = 3%). New or progressing chronic kidney disease events were not found to be statistically different between the lithium and control groups ( n = = 17,740, OR = 2.16, 95% CI: 0.59, 7.94, I 2 = 99%). The high heterogeneity in this meta-analysis limits the reliability and interpretability of our results. Conclusion: Kidney function, as measured by eGFR, was decreased in the lithium-taking groups versus the non-lithium groups. Continuous monitoring and discussion of risks and benefits with patients, especially those with a baseline of reduced kidney function, is imperative. Trial registration: This review was registered prospectively with PROSPERO (CRD42024517414).

Post-COVID syndrome comprises persistent neuropsychiatric manifestations for more than 12 weeks after recovery from acute SARS-CoV-2 infection, yet its underlying pathophysiology is unclear. Ferroptosis, an iron-dependent form of cell death with three hallmarks, iron dysregulation, antioxidant failure, and lipid peroxidation, seems to be involved in COVID-19/post-COVID-19 pathophysiology. Here, we administered the SARS-CoV-2 spike protein S1 subunit intranasally to K18-hACE2 transgenic mice and quantified ferroptotic marker protein expression in four brain regions (hippocampus, prefrontal cortex, cerebellum, and olfactory bulb) at 2, 6, and 12 weeks post-administration, alongside ultrastructural assessment by transmission electron microscopy (TEM) that was limited to the hippocampus and prefrontal cortex. Two-way ANOVA revealed region- and time-dependent modulation of iron-handling, antioxidant, and lipid peroxidation markers. In the hippocampus, FPN1 was significantly increased at 2 weeks, while TFR1 showed a time-dependent pattern without significant week-specific differences. In the prefrontal cortex, DMT1 significantly increased at 2 weeks, and GPx4 showed an overall treatment effect with a trend of increase at 6 weeks. The cerebellum exhibited early increases in FPN1 and GPx4 and a delayed increase in MDA-conjugated proteins. In the olfactory bulb, FPN1 increased at 12 weeks, with GPx4 showing an overall treatment effect and an early trend of decrease. TEM identified ferroptosis-consistent features in the hippocampus and prefrontal cortex at all time points. These findings suggest that spike protein exposure may be associated with time-dependent and brain-region-specific alterations of ferroptosis-related markers. These preliminary findings are based on a limited sample size, which needs further research to elucidate the clinical implication and to study the mechanism in more depth as well as future validation with pharmacological inhibitors.

Background: The effect of intrauterine exposure to SARS-CoV-2 infection during pregnancy on neurodevelopment and growth trajectories during the first year of life remains under investigation. Methods: We retrospectively reviewed the electronic medical records of all pregnant women who received care at Mayo Health System and tested positive for SARS-CoV-2 (RT-PCR) from March 2020 through October 2021 and examined the effects of fetal sex and trimester of maternal SARS-CoV-2 infection on the risk of neurodevelopmental disorder diagnosis and growth trajectories of head circumference (HC) and body weight (BW) percentiles over the first year of life using linear mixed models. Results: We observed that a higher percentage of male infants (n = 357), compared to females (n = 344), have neurodevelopmental disorders (10.9% vs. 5.2%, p = 0.008), and infants exposed to maternal SARS-CoV-2 infection in the second (n = 183) or third trimester (n = 358) have a higher prevalence of neurological diagnoses compared to those exposed in the first trimester (n = 160) (1st vs. 2nd vs. 3rd trimester: 0% vs. 0.9% vs. 0.7%, respectively, p = 0.037). In addition, female infants, compared to males, had significantly lower BW (B = −0.04, p < 0.0001) and HC (B = −0.06, p < 0.0001) percentile growth trajectories over the first year of life. Moreover, infants exposed to maternal SARS-CoV-2 infection in the second trimester had a significantly lower BW percentile growth trajectory (B = −0.01, p = 0.006), while infants exposed to maternal SARS-CoV-2 infection in the third trimester had a significantly lower HC percentile growth trajectory (B = −0.02, p = 0.02). Conclusions: In utero exposure to maternal SARS-CoV-2 infection could have long-term effects on growth trajectories, depending on the infant’s sex and timing of exposure.

Background: The potential long-term effects of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection on the brain structure have not yet been fully elucidated. Even though existing studies have reported structural changes in the post-COVID-19 period, the results remain highly inconsistent and controversial. As such, identifying an imaging biomarker for post-COVID brains is still under investigation. This review aims to comprehensively summarize the structural MRI (sMRI) studies that focus on volumetric brain changes at least two weeks following COVID-19 infection. Methods: A systematic literature search was conducted on PubMed, SCOPUS, Web of Science, EMBASE, and Google Scholar up to 9 September 2025. Studies that utilized sMRI to assess volumetric brain changes post-COVID at greater than two weeks following infection were included. Exclusion criteria encompassed research involving pediatric or adolescent populations and imaging modalities other than sMRI. Preprints, reviews, case reports, case series and post-mortem studies were also excluded. Results: Forty-one studies satisfied the inclusion criteria and consisted of 2895 patients and 1729 healthy controls. Despite the wide variability in image acquisition protocols, data processing methods, and comorbidities between studies, multiple studies reported statistically significant volumetric reductions in the hippocampus, amygdala, thalamus, basal ganglia, nucleus accumbens and the cerebellum months to years after infection, especially in older hospitalized patients with severe COVID-19. Conclusions: The emerging literature reports long-term volume changes across various brain regions in individuals previously infected with COVID-19; however, the evidence is inconsistent. Specific imaging biomarkers following exposure to SARS-CoV-2 infection and the underlying mechanisms of these changes are yet to be identified. Future studies with harmonized imaging protocols, longitudinal designs, and integrated biomarker and clinical data are needed to define robust biomarkers and elucidate the pathophysiology of these findings.

Background: Lithium is a mainstay treatment for bipolar disorder, but its narrow therapeutic index and susceptibility to pharmacokinetic interactions make appropriate monitoring crucial. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, are increasingly prescribed for type 2 diabetes and weight management. Scarce evidence exists on the potential interaction between semaglutide and lithium. Methods: We present 3 cases involving patients on stable lithium regimens who were initiated on semaglutide, reviewing potential mechanisms underlying the interaction between them. Findings: In 2 cases, lithium levels increased significantly, leading to toxicity despite stable renal function and no changes in concurrent medications. In the third case, preemptive reductions in lithium dosage mitigated toxicity, although lithium levels remained higher than anticipated. Mechanistic hypotheses that might contribute to semaglutide-associated elevated lithium levels include altered kidney function, dehydration from reduced oral intake, vomiting, or diarrhea, and delayed gastric emptying. Conclusions: To our knowledge, this is one of the first documented case series describing a potential interaction between semaglutide and lithium in the medical literature. These cases underscore the importance of vigilant monitoring when combining lithium with semaglutide, and potentially other GLP-1 RAs. Baseline renal function, hydration status, and lithium levels should be assessed before initiating semaglutide, and lithium levels should be monitored more frequently during therapy. Clinicians prescribing semaglutide to patients on lithium should exercise caution, monitor for signs of toxicity, and provide appropriate patient education. Further research is needed to elucidate the mechanisms of this potential interaction and its clinical significance.

Objective Studying the effect of deep brain stimulation (DBS) in the lateral hypothalamic area (LHA) in young and aging rats regarding memory changes, hippocampal neuronal dystrophy, and neurofilament expression. Methods Thirty-six male Sprague–Dawley rats were divided into two main groups: adult young (n = 18, 8 weeks old) and aged (n = 18, 24 months old). Each main group was further subdivided into three equal subgroups (n = 6) including control, sham, and DBS. DBS of LHA was conducted using high-frequency electric currents (130 Hz) for 1.5 h with 5-min breaks every 30 min for five consecutive days. Assessment of working memory was done using passive avoidance test (PAT). Then, the brain was dissected and hippocampal neuronal dystrophic damage was assessed as well as immunohistochemical examination of neurofilaments (NF68, NF200) expression. Results Aging rats had progressive hippocampal neuronal degeneration and downregulation of heavy and light chain neurofilaments, that was associated with progressive decline in working memory. Nevertheless, activation of DBS in the LHA enhanced memory function as it increased latency to entry in PAT (P < 0.001) compared to old normal and sham groups. Dystrophic damage score significantly decreased with DBS (P < 0.001) in the hippocampal CA1, CA3, and dentate gyrus regions. Moreover, DBS upregulated hippocampal NF68, NF200 expression (P < 0.001) in both young and old rats. We also found a significant positive correlation between working memory and NFs expression and a negative correlation between dystrophic damage score and NFs expression. Conclusions DBS in the LHA may have a neuroprotective effect in aging rats as it enhanced the working memory and decreased hippocampal neuronal dystrophy. This protective effect may be caused by the upregulation of neurofilaments.
