Over time, studies have shown the importance of determining serotonin levels to diagnose somatic and psychiatric disorders. There are theoretical premises and practical ways to achieve a subtle correlation between the existence of comorbid psychiatric disorders and somatic diseases caused by the changes observed in serotonin levels. The present study, classified as retrospective and quantitative, provides evidence for determining the serotonin levels in patients with diabetes and anxiety or depression. A total of 48 patients with diabetes type 2 were enrolled in the study. Blood glucose level, glycated haemoglobin, and serum serotonin were noted, and they completed Hamilton A and Beck Depression Inventory questionnaires. We found robust correlations between serum serotonin and blood glucose (Sig. = 0.008), serum serotonin and HbA1c (Sig. = 0.007), serum serotonin and anxiety (Sig. = 0.000), and serum serotonin and depression (Sig. = 0.000). It is also noteworthy that women recorded extreme values higher than men for glycated haemoglobin (95% confidence interval: 6.92–7.79 in women and 6.30–7.23 in men). In conclusion, using serotonin as a marker of the mentioned diseases in clinical practice is of significant utility, considering the benefits in terms of the evolution and prognosis of comorbidities in patients with type 2 diabetes and anxiety and depressive symptoms.

Autism Spectrum Disorder (ASD) has been associated with disruptions in one-carbon metabolism and vitamin D pathways. Nutritional exposures—particularly vitamin D, vitamin B₁₂, and homocysteine—may influence neurodevelopmental outcomes. However, a comprehensive, lifespan-spanning synthesis of these modifiable nutritional biomarkers has not been conducted. This systematic review and stratified meta-analysis critically synthesized data on vitamin D, vitamin B₁₂, and homocysteine to elucidate their relationships with ASD risk and symptomatology. Our central question was: How do levels of vitamin D, vitamin B₁₂, and homocysteine—measured before and after birth—affect the risk, severity, and potential treatment outcomes for ASD? We conducted a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) compliant systematic review and stratified meta-analysis (2015–2025) of 35 studies (11 randomized controlled trials, 24 observational), examining prenatal, neonatal, and postnatal biomarker levels. Eligibility criteria were defined using the PICOS (Population, Intervention, Comparator, Outcome, and Study Design) framework to ensure scientific rigor and clinical relevance, including studies involving human participants aged 0–18 years with a formal Autism Spectrum Disorder (ASD) diagnosis or prenatal exposures potentially linked to later ASD onset, while excluding animal studies, adult-only ASD populations, and studies lacking ASD cohorts or biomarker data. The search strategy, developed according to PRISMA, and Cochrane best practices, encompassed five major databases (PubMed/MEDLINE, Cochrane Library, Google Scholar, ClinicalTrials.gov, and ProQuest) alongside manual searches of key references, grey literature, and clinical trial registries to ensure comprehensive retrieval of both published and unpublished studies. Study quality was assessed using version 2 of the Cochrane risk-of-bias tool for RCTs (RoB2) and the Newcastle–Ottawa Scale (NOS) for observational studies; certainty of evidence was graded via GRADE (Grading of Recommendations Assessment, Development and Evaluation). Random-effects meta-analyses were stratified by biomarker and study design. Heterogeneity, small-study effects, and publication bias were evaluated using Cochran’s Q, I², Egger’s test, and trim-and-fill. Prenatal vitamin D deficiency was associated with approximately two-fold increased odds of Autism Spectrum Disorder (ASD) in offspring (pooled OR ≈ 2.0; p < 0.05), while excessively elevated maternal B₁₂ concentrations, often co-occurring with folate excess, were similarly linked to increased ASD risk. Meta-analytic comparisons revealed significantly lower circulating vitamin D (SMD ≈ −1.0; p < 0.001) and B₁₂ levels (SMD ≈ −0.7; p < 0.001), alongside elevated homocysteine (SMD ≈ 0.7; p < 0.001), in children with ASD versus neurotypical controls. Early-life vitamin D/B₁₂ insufficiency and elevated homocysteine are important, modifiable correlates of ASD risk and severity. Adequate maternal and child nutritional status could have risk-reducing and symptom-mitigating effects, although causality remains to be confirmed. This evidence supports tailored nutritional interventions as a component of ASD risk reduction and management strategies, within the bounds of overall developmental healthcare.

The review was not prospectively registered in PROSPERO or any other systematic review registry.

The outbreak of SARS-CoV-2 pandemic has resulted in increased rates of anxiety and depression worldwide. Objective. To comparatively evaluate factors associated with the psychological impact of Coronavirus disease between 2019 and the pandemic year 2020. Materials and Methods. The study was performed on a group of 3224 patients, of which 197 were hospitalized, selected from 1 Jan 2019 until 30 Dec 2020 in a tertiary care center for psychiatric disorders. Data were collected from the observation charts. Results. The incidence of anxiety disorders is higher in the age range 40–70 years with an average value of 53 years old. In 2019, a third of patients (29.45%) had alcohol-related conditions and developed anxiety-depressive disorder. In 2020, the percentage was lower (9.38%), but also the number of admitted patients significantly decreased (p < 0.0001). There were not found significant differences in age, gender or environment. Hypnotic disorders were more predominant in 2019 (54.6% vs. 37.5%, p = 0.01), whereas in 2020 anxiety and agitation increased significantly (34.4% vs. 84.38%, p = 0.0001). Relapses were similarly frequent in both years, in half of the cases. Conclusions. Coronavirus pandemic lead to a decrease in both presentations and admission to hospital. Although there were not found significant differences in age or gender, more patients from urban environment were admitted, which can have several explanations. Anxiety and agitation became the main reason for hospitalization in 2020.

Background/Objectives: Alcohol consumption in young persons is a growing phenomenon, with significant implications for physical and mental health. This behavior exposes adolescents and young adults to multiple risks, such as affecting cognitive functions, the development of emotional disorders, and social integration difficulties. The present study sets out to investigate the way alcohol consumption influences emotionality in young people, focusing on the emotional changes (anxiety and irritability), cognitive changes (attention deficit and memory disorder), and behavioral changes (impulsivity and aggressiveness). Methods: The methodology involved collecting quantitative data from a sample of young people who consume and do not consume alcohol, using standardized questionnaires and advanced statistical software (processed in MATLAB version 9.11_R2021b). We analyzed variables such as consumption frequency and intensity, affective scores, and demographic factors to highlight the correlations between consumption level and the intensity of affective modifications. Results: The results revealed a significant association between alcohol consumption and the rise in anxiety and depression symptoms or a tendency toward impulsive behaviors. Additionally, we observed that psychosocial factors, including group pressure, family climate, and stressful contexts, can exacerbate emotional vulnerability. Conclusions: This study suggests the need for early psychological interventions and prevention programs to approach emotional and cognitive dimensions and the social influences associated with consumption. Implementing support and counseling strategies, as well as education and awareness campaigns, can contribute to reducing risky behavior and promoting young people’s harmonious development.

Although obesity is a frequently formulated diagnosis at all ages, due to the long-term projection of the consequences of this condition in children it is a real public health problem. The etiology of obesity is multiple and its complexity requires a multidisciplinary medical approach from which the psychological component cannot be omitted. Thus, diseases such as diabetes, dyslipidemias, cardiovascular diseases, sleep apnea syndrome, non-alcoholic fatty liver or neoplasia are encountered with a higher incidence in this category of individuals. During the COVID-19 pandemic, the isolation and, consequently, the reduction of access to ways of performing physical exercise increased the balance between caloric intake and caloric consumption resulting in the accumulation of surplus calories in the form of adipose tissue. The purpose of the present work is to emphasize the interest manifested by the medical scientific world regarding obesity in the pediatric population, in the pre-pandemic period, during the pandemic period and one year after its’ end (2018-2023). We performed systematic review of clinical studies on obesity in the pediatric population, including 98 articles published in the PubMed database. The number of studies published during the pandemic period (53) vs the number of studies published ex-pandemic (45), corresponds to a ratio of 1.17:1 in favor of the first. Obesity remains a research topic of major interest in early life, regardless of the coexistence of COVID-19.

Post-partum depression is one of the most severe types of depression and can be developed at any age, no matter of cultural of social status. Objectives. To determine the factors associated with the psychological impact of pregnancy and to emphasize the psychological and psychiatric risks after giving birth for a woman. Materials and Methods. The study enrolled 35 patients diagnosed with postpartum depression that have been hospitalized in a tertiary-care center for psychiatric disorders between 2016 and 2020. Data were collected from patients’ observation charts. Results. The incidence of postpartum depression is higher in the age range 30-45 years old for primiparous women who are from urban areas, unemployed and not integrated in a family (unbalanced families or single parents), with medium level of education (high school) and alcohol addiction. One of 35 patients committed infanticide. Conclusions. Even if the postpartum depression is known worldwide it is still underdiagnosed, with certain factors concurring to that. Postpartum depression requires the identification of risk conditions in pregnant women and individualized therapy in a patient-centered, holistic manner.
