A Longitudinal Cohort Study of Youth Mental Health and Substance use Before and During the COVID-19 Pandemic in Ontario,Canada: An Exploratory Analysis

BackgroundYouth mental health appears to have been negatively impacted by the COVID-19 pandemic. The impact on substance use is less clear, as is the impact on subgroups of youth, including those with pre-existing mental health or substance use challenges.ObjectiveThis hypothesis-generating study examines the longitudinal evolution of youth mental health and substance use from before the COVID-19 pandemic to over one year into the pandemic among youth with pre-existing mental health or substance use challenges.MethodA total of 168 youth aged 14–24 participated. Participants provided sociodemographic data, as well as internalizing disorder, externalizing disorder, and substance use data prior to the pandemic’s onset, then every two months between April 2020–2021. Linear mixed models and Generalized Estimating Equations were used to analyze the effect of time on mental health and substance use. Exploratory analyses were conducted to examine interactions with sociodemographic and clinical characteristics.ResultsThere was no change in internalizing or externalizing disorder scores from prior to the pandemic to any point throughout the first year of the pandemic. Substance use scores during the pandemic declined compared to pre-pandemic scores. Exploratory analyses suggest that students appear to have experienced more mental health repercussions than non-students; other sociodemographic and clinical characteristics did not appear to be associated with mental health or substance use trajectories.ConclusionsWhile mental health remained stable and substance use declined from before the COVID-19 pandemic to during the pandemic among youth with pre-existing mental health challenges, some youth experienced greater challenges than others. Longitudinal monitoring among various population subgroups is crucial to identifying higher risk populations. This information is needed to provide empirical evidence to inform future research directions.

Anxiety and depression symptoms in infertile men during their first infertility evaluation visit

Objective: To assess the psychological condition of men at the start of the infertility work-up.

Methods: Men seeking an infertility evaluation for the first time were recruited. Depression and anxiety symptoms and subjective psychological burden were assessed with the Beck Depression Inventory (BDI), the Spielberger State-Trait Anxiety Inventory (STAI), and a visual analog scale (VAS).

Results: Data from 113 patients were analyzed. The mean age of the patients was 33.3 (range: 23–54) years, whereas the mean duration of infertility was 16.3 (range: 0–96) months. Results from the BDI and STAI were 2.24 (SD: ±3.18) and 33.74 (SD: ±8.04). Mild depressive symptoms were found in 4.5% of patients, whereas anxiety reached an abnormal level in 4.9%. There were significant correlations between the results from the BDI score and the duration of infertility (p?=?.024), whereas the STAI and VAS scores showed no similar connection (p?=?.142 and p?=?.261, respectively). Among patients with infertility longer than 2 years, mild depressive symptoms occurred in 23.1%.

Conclusion: Among men, the levels of depressive and anxiety symptoms were low at the start of the infertility work-up. Depressive symptom levels increased significantly with the duration of infertility, whereas anxiety levels and VAS scores did not demonstrate a similar correlation.     

Prevalence and risk of colorectal polyps among the Korean population under 50 years

Colorectal cancer is a common cancer; generally, adults aged ≥ 50 years are screened using stool occult blood tests and colonoscopy. However, colorectal adenoma and cancer have been found in patients under the aged of 50, and studies on characteristics and risk factors in young patients are lacking. We evaluated the prevalence and risk factors of colorectal adenoma and cancer in young adults aged under 50 years.We retrospectively analyzed 570 individuals aged under 50 years who underwent colonoscopy at the Haeundae Paik Hospital, Korea, from January to June 2018. Logistic regression model was used to identify the risk factors for colorectal adenoma and colorectal cancer.The prevalence of colorectal adenoma in group of 19–29 years was 3.2% (1 of 31), 30–39 years was 13.8% (30 of 217) and in the group of 40–49 years was 21.1% (68 of 322) (P = .009). In multivariable analysis, age over 45 years (adjusted odds ratio [OR], 1.941; 95% confidence interval [CI], 1.187–3.172; P = .008) and male sex (adjusted OR, 1.711; 95% CI, 1.044–2.806; P = .033) were independent risk factors for colorectal neoplasia including cancer.The prevalence of colorectal adenoma increases as the age increased in young adults under 50 years of age, especially after the age of 45 years, the risk of colorectal neoplasia increases; hence, early screening should be considered before the age of 50 years.     

Primary ovarian abscess in virginal young woman with huge endometriosis cyst: A case report

Rationale:Primary ovarian abscess which develops as an isolated lesion without simultaneous tubal infection is a rare entity. Ovarian abscess (OA) is a serious complication of pelvic inflammatory disease (PID) rarely seen in virginal girls. Early diagnosis and treatment are essential to prevent further sequela including infertility, ectopic pregnancy, and chronic pelvic pain.Patient concerns:A 19-year-old virginal girl who presented with abdominal pain and pelvic mass with no risk factors.Diagnoses:Laparoscopic surgery was performed to confirm a primary ovarian abscess in the adolescent virginal female with a huge endometriosis cyst.Intervention:Ovarian abscess with extensive intestinal adhesions was determined during the laparoscopic operation. Abscess drainage and postoperative antibiotic therapy cured the patient.Outcome:After the surgery, the CRP level on the day of discharge was 3.18 mg/d. The histological findings revealed a cystic tissue sample with the fibrous wall infiltrated by neutrophilic granulocytes, and ectopic endometrium, suggesting abscess formation in the ovary and endometriosis cyst.Lessons:Although primary ovarian abscess in an adolescent virginal female is rare, given the severity of outcomes following ovarian abscess, this pathology should be considered in the differential diagnosis of virginal adolescents with fever and abdominal pain.

Habitual Total Drinking Fluid Intake Did Not Affect Plasma Hydration Biomarkers among Young Male Athletes in Beijing,China: A Cross-Sectional Study

The purposes of this study were to explore the drinking patterns, and urinary and plasma hydration biomarkers of young adults with different levels of habitual total drinking fluid intake. A cross-sectional study was conducted among 111 young male athletes in Beijing, China. Total drinking fluids and water from food were assessed by a 7-day, 24-h fluid intake questionnaire and the duplicate portion method, respectively. The osmolality and electrolyte concentrations of the 24-h urine and fasting blood samples were tested. Differences in groups LD₁ (low drinker), LD₂, HD₁, and HD₂ (high drinker), divided according to the quartiles of total drinking fluids, were compared using one-way ANOVA, Kruskal–Wallis H-tests, and chi-squared tests. A total of 109 subjects completed the study. The HD₂ group had greater amounts of TWI (total water intake) and higher and lower contributions of total drinking fluids and water from food to TWI, respectively, than the LD₁, LD₂, and HD₁ groups (p < 0.05), but the amounts of water from food did not differ significantly among the four groups (all p > 0.05). Participants in the HD₂ group had higher amounts of water than participants in the LD₁, LD₂, and HD₁ groups (p < 0.05); SSBs were the second top contributor of total drinking fluids, ranging from 24.0% to 31.8%. The percentage of subjects in optimal hydration status increased from 11.8% in the LD₁ group to 58.8% in the HD₂ group (p < 0.05). The HD₂ and HD₁ groups had 212–227 higher volumes of urine than the LD₁ and LD₂ groups (p < 0.05). No significant differences were found in the plasma biomarkers (p > 0.05), with the exception of higher concentrations of K in the HD₁ group than in the LD₁ group (p < 0.05). Subjects with higher amounts of total drinking fluids had better hydration status than those with lower total drinking fluids, but not better drinking patterns. Habitual total drinking fluids did not affect the plasma biomarkers.
