Adolescence represents a critical developmental stage where diet, gut microorganisms, and mental health are strongly interconnected. The current literature evidences the bidirectional role between dietary habits and psychological well-being, which is mediated by the gut–brain axis. The purpose of this review is to highlight the importance of dietary habits in adolescence period and the impact of different food choices on microbiota and secondary on mental health. Gut microbiota plays a vital role in the synthesis of neurotransmitters such as serotonin, dopamine, noradrenaline, and metabolites like short-chain fatty acids (SCFAs). The disruption in the composition of microbiota is called dysbiosis, which has been associated with a systemic inflammation state and chronic stress. They contribute to the onset of psychiatric disorders including MDD, anxiety, ADHD, and autism. Diets with a high quantity of sugar and low fiber contribute to alteration of microbiota and poor mental health. Additionally, early-life stress, antibiotic usage, and chronic inflammation may alter bacterial communities, with long-term implications for adolescents mental health. Dietary interventions, including the intake of prebiotics, probiotics, SCFAs, and micronutrients could restore microbial balance and improve psychiatric symptoms. This literature review highlights the critical role of diet and gut microbiota for adolescent mental health and emphasizes the need for integrative strategies to promote psychological resilience through microbiome regulation.

Background/Objectives: Preterm birth is defined by the World Health Organization (WHO) as birth occurring before 37 weeks of gestation and represents one of the major public health concerns worldwide. Approximately 15 million newborns are affected annually. Following such a physically and emotionally traumatic event, most parents experience emotional distress and seek answers regarding the possible internal or external triggers. The main objective of this review is to analyze the current data regarding the impact of prematurity on parental mental health, as well as the types of interventions targeting parents. Methods: This narrative review was conducted based on extensive research of full-text scientific articles published in the past 15 years, investigating the relationship between prematurity, neonatal intensive care unit (NICU) hospitalization, parental mental health, and proposed intervention strategies aimed at supporting families. Results: Approximately 35% of mothers of preterm infants presented postpartum depression, 24% anxiety, and 15% PTSD. FCC interventions reduced stress levels and the intensity of depressive symptoms, while FICare showed stronger benefits, with additional improvements in parental mental health, parental self-efficacy, increased parental confidence, and amelioration of preterm infant parameters. Conclusions: Implementing FCC and FICare into daily neonatal care is essential for the prevention of parental mental health disorders and strengthening parenting capacity.

Background: The prevalence of dental caries has increased among children, largely due to nutritional habits or inadequate access to dental care. The present study aimed to investigate the prevalence of dental caries associated with various factors that lead to their appearance, such as food intake and body composition, among Romanian school-age children from two counties, Bistriţa Năsăud and Mureş. Methods: This cross-sectional study included 1100 children aged 6–10 years from two Romanian counties. Dental caries experience was assessed using the DMFT and dmft indices based on WHO criteria. Dietary intake and oral health behaviors were evaluated through a food frequency questionnaire completed by parents. Associations between dietary variables and dental caries were assessed using independent sample t-tests and Mann–Whitney U tests. A binary logistic regression model was used to estimate the likelihood of caries in the permanent dentition (DMFT > 0), with covariates including county, parental education, daily sugar intake, consumption of dairy products, body mass index (BMI), and waist-to-height ratio. Results: It was found that the children who daily consume cheese recorded a DMFT value lower than the children who did not consume (p < 0.05). Moreover, those who consume sugary foods recorded higher values of DMFT as compared with those who did not (p < 0.05). The body weight, BMI, and waist circumference are positively correlated with DMFT, but negatively with dmft (p < 0.05). The overall prevalence of caries was 79.8% in primary dentition and 63.6% in permanent dentition, with slightly higher rates observed in Bistriţa-Năsăud County compared to Mureş. It seems that the predictors of the caries’s presence among children include the mother’s education level, sugar intake frequency, and body fat ratio. Conclusions: Based on significant associations found, one can affirm that the dental caries of the Romanian school-age children is due to sugary food intake and body composition. In addition, the direct relationship between dental caries and childhood obesity showed through the correlation of BMI and dental health indices denotes that school-age children should reduce sugary foods and increase dairy products.

Background: Young adulthood represents a critical period for the emergence of early metabolic disturbances, potentially influenced by dietary shifts toward convenience and ultra-processed foods. However, evidence linking dietary patterns and cooking practices with objective metabolic biomarkers in Romanian university students remains limited. Methods: This cross-sectional study included 693 students aged 18–24 years at the Victor Babeș University of Medicine and Pharmacy, Romania (June–July 2025). Dietary habits, food preferences, and cooking practices were assessed using a structured online questionnaire, while anthropometric and biochemical data were obtained from university health records. The primary outcome was glycated hemoglobin (HbA1c), a marker of average blood glucose levels over the previous 2–3 months. Prediabetes was defined as HbA1c 5.7–6.4%. Dietary patterns were identified using k-means clustering based on fast-food consumption frequency, main meal of the day, fruit and vegetable intake frequency, and predominant cooking method. Multivariable regression models assessed associations between dietary variables and glycemic or lipid outcomes. Results: Prediabetes prevalence was 21.1% (diabetes: 1.4%). Three dietary patterns were identified: health-conscious (prediabetes 15.4%), mixed (20.0%), and fast-food oriented (27.3%; χ² p = 0.003). Fast-food consumption frequency was independently associated with higher prediabetes risk (OR = 1.78 per category; 95% CI 1.38–2.30; p < 0.001) and higher HbA1c levels (β = 0.147; p < 0.001), while fruit and vegetable intake showed an inverse association with HbA1c (β = −0.109; p < 0.001). A dose–response relationship was observed between fast-food frequency and both HbA1c and prediabetes prevalence (p-trend < 0.001). An interaction between high-temperature cooking methods and frequent fast-food consumption was observed for HbA1c (p = 0.023). BMI and sex were the strongest predictors of lipid outcomes, although fast-food intake was associated with higher triglyceride levels (p = 0.034). Conclusions: Among Romanian university students, dietary patterns characterized by frequent fast-food consumption were associated with higher HbA1c levels and greater prediabetes prevalence. A high-temperature cooking method was associated with higher glycemic levels when combined with frequent fast-food intake. These findings suggest that early dietary behaviors during university years may be relevant for metabolic risk profiles in young adults.

Background: Childhood cancers account for approximately 1–2% of all malignancies worldwide, with hematologic cancers representing about 35–40% of pediatric cases. Improved survival has brought increased recognition of both acute and long-term therapy-related complications, including secondary malignant neoplasms (SMNs). Survivors of pediatric hematologic malignancies face a lifelong risk of secondary malignant neoplasms (SMNs), which remain among the most severe late effects of therapy. Methods: We conducted a PRISMA 2020–aligned systematic review of cohort and registry studies evaluating SMNs after childhood hematologic cancers. Databases searched included PubMed, Embase, Web of Science, Scopus, and Cochrane Library. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Newcastle–Ottawa Scale; disagreements were resolved by a third reviewer. Results: Forty-three studies (>70,000 survivors, median follow-up 5–30+ years) were included. Standardized incidence ratios (SIRs) for secondary malignant neoplasms compared to the general population ranged from 2.0 to 6.0, with absolute excess risks (AERs) of approximately 10–40 per 10,000 person-years. Therapy-related acute myeloid leukemia occurred within 5–10 years, while solid secondary malignant neoplasms (breast, thyroid, central nervous system, sarcomas) emerged after 10–25 years. The highest risks for developing secondary malignant neoplasms were observed among female survivors of Hodgkin lymphoma treated with chest and neck radiotherapy, particularly during adolescence, and among hematopoietic stem cell transplant recipients exposed to total body irradiation or chronic graft-versus-host disease. Conclusions: SMNs are predictable late effects requiring lifelong, exposure-anchored surveillance. Precision survivorship—integrating treatment exposures, transplant conditioning, and genetic predisposition—should guide future screening strategies.

Background/Objectives: Disorders of Gut–Brain Interaction (DGBIs), particularly irritable bowel syndrome (IBS), are frequently underdiagnosed in clinical practice, contributing to a substantial hidden burden of disease. This study aimed to quantify this “symptomatic iceberg” by comparing the prevalence of formal IBS diagnoses with a broader symptom-based case definition in a clinical cohort. Methods: We conducted a cross-sectional analysis of 194 adult subjects from a gastroenterology clinic in Western Romania. Data on demographics, clinical diagnoses, self-reported symptoms, and eating behaviors were collected. For the case–control analysis, patients with confirmed organic gastrointestinal pathology or incomplete data were excluded. The final analytical sample consisted of 52 patients classified as having a functional DGBI phenotype and 84 asymptomatic controls without organic disease, while 58 were excluded from the analysis. Results: While only 4.4% (95% CI: 2.0–9.3%) of the cohort (N = 136) had a formal IBS diagnosis, 47.8% (95% CI: 39.6–56.1%) met criteria for an IBS-compatible symptom cluster, yielding an underdiagnosis ratio of 10.8. Neuro-vegetative symptoms such as sweating (19.1%) and dizziness (11.8%) were highly prevalent. In the case–control analysis, patients with a functional DGBI phenotype had a significantly higher mean BMI compared to controls (28.15 ± 6.49 vs. 24.47 ± 4.60 kg/m²; p = 0.001). DGBI cases were less likely to report regular snacking behavior (OR = 0.36; 95% CI: 0.18–0.74; p = 0.009), suggesting behavioral adaptation. A sensitivity analysis excluding participants with CRP > 10 mg/L (n = 98) confirmed the robustness of these associations, indicating that minor systemic inflammation did not bias the primary findings.
