Abstract
Previous studies on the relationship between zinc and metabolic syndrome (MetS) have yielded inconsistent results. This comprehensive study aimed to elaborately explore the impact of zinc on MetS risk factors. The bi-directional Mendelian randomization (MR) analyses were performed to estimate the causal relationship between zinc and MetS risk factors. Additionally, a retrospective cross-sectional study incorporated 4389 subjects to provide a broader perspective in conjunction with the MR analyses. In the MR analyses, genetically instrumented zinc was positively associated with five of the MetS components in Europeans, including BMI, FBG, HbA1c, TC, and LDL-c (β (95%CI) = 0.023 (0.019-0.027), 0.019 (0.013-0.025), 0.041 (0.022-0.060), 0.027 (0.013-0.042), and 0.018 (0.010-0.026), respectively). In the cross-sectional study, higher concentration of zinc was strongly associated with increased BMI, LDL-c, and UA (β (95%CI) = 0.040 (0.010-0.085), 0.026 (0.018-0.035), and 1.529 (0.614-2.445), respectively). Moreover, these unfavorable associations were more obvious in women compared to men, with a borderline significant interaction effect for BMI (P=0.051). Our study showed that higher blood concentration of zinc, an essential trace element, was associated with unfavorable changes of the component metabolic risk factors of MetS, especially with BMI and LDL-c. Notably, these associations seemed to be more pronounced in women rather than in men. Further studies are warranted to elucidate the role of zinc status in the underlying mechanisms of MetS.

Mötteli S, Vetter S, Colla M, Hotzy F. Are probiotics effective in reducing the metabolic side effects of psychiatric medication? A scoping review of evidence from clinical studies. Transl Psychiatry 2024; 14:26. [PMID: 38225232 PMCID: PMC10789870 DOI: 10.1038/s41398-024-02735-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 12/19/2023] [Accepted: 01/02/2024] [Indexed: 01/17/2024] Open
Abstract
The psychopharmacological treatment of patients with schizophrenia or depression is often accompanied by serious side effects. In particular, the clinical findings of weight gain are worrying, as this side effect can lead to various medical sequelae in the future. However, the treatment of metabolic changes in psychiatric patients is often neglected or unsuccessful. An improved knowledge of possible therapeutic approaches is needed. The aim of this study was to provide an overview of the utilisation and effectiveness of probiotics in reducing weight gain in patients with severe mental illness. A scoping review of studies published until 15 June 2022 was conducted to identify studies using probiotics in people with schizophrenia or depression. We systematically searched the databases EMBASE, PubMed (MEDLINE), Web of Science and SCOPUS with a predefined search string. In addition, reference lists of relevant publications were examined for additional studies. The studies were assessed by two reviewers. The primary outcomes were weight-related measurements. The secondary outcomes were metabolic blood parameters and gut microbiota. Four studies ultimately met the inclusion criteria. Two studies in which probiotics were administered did not find significant effects on pharmacologically induced weight gain. The other two studies examined the effects of synbiotics (a combination of probiotics and prebiotics). Interestingly, less weight gain was observed in individuals with this combined intervention. Adjustments in diet can be helpful and are generally well-accepted interventions in the fight against pharmacologically induced weight gain. The clinical use of probiotics and prebiotics (or synbiotics) as dietary interventions may represent a promising additional strategy in this regard. However, the few studies available showed no clear conclusions.

Abstract
African Americans have a higher prevalence of obesity and obesity-related diseases than other racial/ethnic groups; among persons with serious mental illness (SMI), African Americans fare worse as well. This qualitative study focused on the perceptions of African Americans with SMI in regard to 1) their experiences with diet and exercise behaviors post trauma and 2) how diet and exercise programming can address trauma. A community-based participatory research (CBPR) team developed the interview guide, research protocols, and conducted three focus groups. The team used thematic analysis to analyze the data. Participant (N = 27) responses on the experience of trauma were coded into the following themes: 1) emotional eating, 2) appetite loss, 3) hesitancy to exercise due to community violence, 4) staying home due to mental health symptoms, and 5) substance use. Themes around how programming can address trauma included: 1) support, 2) communication, 3) strategies to avoid trauma, and 4) engagement in programming. Findings suggest the need for human service professionals to infuse trauma-informed communications and practices throughout programming, incorporate peer-led services and address concerns related to community violence.
