ABSTRACT

BACKGROUND: The outbreak of the COVID-19 pandemic in 2020 aggravated already existing difficulties and added new challenges for students. Owing to the gap between needed and available psychological services, group interventions may offer a helpful strategy for student mental health promotion.

OBJECTIVE: This study aimed to investigate the acceptability and feasibility of a 4-week online support group program designed for mental health promotion tailored to graduate students at a Brazilian public university in the context of the COVID-19 pandemic (May 2022 to June 2022).

METHODS: Participants in the program took part in online support groups based on a pilot group facilitated by a trained clinical psychologist. Self-administered, standardized web-based questionnaires were assessed at the baseline (T0; before the intervention), postintervention (T2), and follow-up (T3; after 4-6 weeks) time points. We measured sociodemographic variables, treatment credibility and expectancy (Credibility and Expectancy Questionnaire), satisfaction (Client Satisfaction Questionnaire), negative effects of the intervention (Negative Effects Questionnaire), depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]), and participants’ quality of life (abbreviated World Health Organization Quality of Life assessment). A 9-answer option questionnaire and open-ended questions also assessed the group’s perceived positive and negative outcomes.

RESULTS: The total sample comprised 32 participants. Most (23/32, 72%) were doctoral students. Credibility and expectancy scores were high. Participants’ satisfaction (Client Satisfaction Questionnaire) with the program was high at the postintervention (T2) and follow-up (T3) evaluations (T2: mean 28.66, SD 3.02; T3: mean 27.91, SD 3.02). Most participants reported that they could learn from other participants’ experiences (T2: 29/32, 91%; T3: 27/32, 84%) and felt encouraged to take better care of themselves (T2: 22/32, 69%; T3: 24/32, 75%). None of the participants reported that they had no benefits from the program. The PHQ-9 scores showed mild to moderate depressive symptoms (mean 9.59, SD 6.34), whereas the answers of 9% (3/32) of the participants to the PHQ-9 item 9 indicated suicidality at baseline (T0). Finally, the 4 domains of quality of life (physical: P=.01; psychological: P=.004; social: P=.02; and environmental: P<.001) showed a slight and statistically significant improvement at the postintervention evaluation (T0: mean 57.03, SD 15.39 to 59.64, SD 17.21; T2: mean 64.32, SD 11.97 to 68.75, SD 8.87).

CONCLUSIONS: Online support groups for the mental health promotion of graduate students are feasible and can be especially useful for universities with students allocated to different cities. They are also satisfactory and may positively influence participants’ quality of life. Therefore, they can be considered a helpful mental health promotion strategy in the educational context. Further studies could evaluate these (or similar) programs under nonpandemic circumstances.

ABSTRACT

IMPORTANCE: Clinical studies confirm that obesity is a risk factor for recurrence in postmenopausal women with hormone receptor-positive (HR+) breast cancer. Evidence suggests that women with obesity do not obtain similar protection from aromatase inhibitors as women with healthy weight.

OBJECTIVE: To examine the associations of body mass index (BMI) with recurrence.

DESIGN, SETTING, AND PARTICIPANTS: The cohort study was conducted using data from the Danish Breast Cancer Group and enrolled postmenopausal women diagnosed with stage I to III HR+ breast cancer from 1998 through 2016. Data analysis was conducted from November 2022 to April 2023.

EXPOSURES: BMI was classified as (1) healthy weight (18.5-24.9), (2) overweight (25.0-29.9), (3) obesity (30.0-34.9), and (4) severe obesity (≥35.0) using the World Health Organization guidelines. Healthy weight was considered the reference group in statistical analyses.

MAIN OUTCOMES AND MEASURES: Follow-up began 6 months after breast cancer surgery and continued until the first event of recurrence, contralateral breast cancer, new primary malignant neoplasm, death, emigration, end of clinical follow-up at 10 years, or September 25, 2018. Cox regression was used to estimate crude and adjusted hazard ratios with 95% CIs, adjusting for patient, tumor, and treatment characteristics.

RESULTS: A total of 13 230 patients (median [IQR] age at diagnosis, 64.4 [58.6-70.2] years) with information on BMI were enrolled. There were 1587 recurrences with a median (IQR) potential estimated follow-up of 6.2 (3.6-8.5) years. Multivariable analyses revealed increased recurrence hazards associated with obesity (adjusted hazard ratio, 1.18 [95% CI, 1.01-1.37]) and severe obesity (adjusted hazard ratio, 1.32 [95% CI, 1.08-1.62]) vs patients with healthy weight. Patients with overweight had a greater risk, but the results were not statistically significant (adjusted hazard ratio, 1.10 [95% CI, 0.97-1.24]).

CONCLUSIONS AND RELEVANCE: In this study, obesity was associated with an increased risk of breast cancer recurrence among postmenopausal patients with HR+ early-stage breast cancer treated with aromatase inhibitors. Physicians should be aware of the significance of obesity on breast cancer outcomes to secure optimal treatment benefit in all patients.

ABSTRACT

IMPORTANCE: Rates of hospital-acquired venous thromboembolism (HA-VTE) are increasing among pediatric patients. Identifying at-risk patients for whom prophylactic interventions should be considered remains challenging.

OBJECTIVE: To determine whether use of a previously validated HA-VTE prognostic model, together with pediatric hematologist review, could reduce pediatric inpatient rates of HA-VTE.

DESIGN, SETTING, AND PARTICIPANTS: This pragmatic randomized clinical trial was performed from November 2, 2020, through January 31, 2022, at a single-center academic children’s hospital (Monroe Carell Jr Children’s Hospital at Vanderbilt). All pediatric hospital admissions (aged <22 years) under inpatient status were included and randomized.

INTERVENTION: All patients had an HA-VTE probability automatically calculated daily, which was visible to the hematology research team for patients in the intervention group. Patients with an elevated risk (predicted probability ≥2.5%) underwent additional medical record review by the research team to determine eligibility for thromboprophylaxis.

MAIN OUTCOMES AND MEASURES: The primary outcome was rate of HA-VTE. Secondary outcomes included rates of prophylactic anticoagulation and anticoagulation-associated bleeding events.

RESULTS: A total of 17 427 hospitalizations met eligibility criteria, were randomized, and were included in the primary analysis: patients had a median (IQR) age of 1.7 (0 to 11.1) years; there were 9143 (52.5%) female patients and 8284 (47.5%) male patients, and there were 445 (2.6%) Asian patients, 2739 (15.9%) Black patients, and 11 752 (67.4%) White patients. The 2 groups were evenly balanced in number (8717 in the intervention group and 8710 in the control group) and patient characteristics. A total of 58 patients (0.7%) in the control group and 77 (0.9%) in the intervention group developed HA-VTE (risk difference: 2.2 per 1000 patients; 95% CI, -0.4 to 4.8 per 1000 patients; P = .10). Recommendations to initiate thromboprophylaxis were accepted by primary clinical teams 25.8% of the time (74 of 287 hospitalizations). Minor bleeding events were rare among patients who received anticoagulation (3 of 74 [4.1%]), and no major bleeding events were observed during the study period. Among patients randomized to the control group, the model exhibited high discrimination accuracy (C statistic, 0.799, 95% CI, 0.725 to 0.856).

CONCLUSIONS AND RELEVANCE: In this randomized clinical trial of the use of a HA-VTE prognostic model to reduce pediatric inpatient rates of HA-VTE, despite the use of an accurate and validated prognostic model for HA-VTE, there was substantial reluctance by primary clinical teams to initiate thromboprophylaxis as recommended. In this context, rates of HA-VTE between the control and intervention groups were not different. Future research is needed to identify improved strategies for prevention of HA-VTE and to overcome clinician concerns regarding thromboprophylaxis.

ABSTRACT

PURPOSE: Low- to middle-income nations contain more than 80% of the world’s population; however, only 4% of articles in ophthalmology journals belong to these countries. We aim to analyze the global diversity of the editorial boards of ophthalmology journals.

METHODS: Cross-sectional study, including all journals in the Ophthalmology section of the SCImago Journal & Country Rank (SJR). Journals were classified according to the country of origin, SJR interquartile range (Q1-Q4), impact factor, and open-access policy. Global diversity among journals was determined by the country of affiliation of editors-in-chief and editorial board members. Nations were classified by income according to the World Bank’s 2022 system. The association between editorial diversity and the journal’s metrics and country of origin was analyzed using the χ2 test and the Mann-Whitney U test.

RESULTS: A total of 116 journals were included and 83.6% belonged to high-income nations. Only 18 (13.3%) editors-in-chief and 582 (13.5%) board members were affiliated with middle-income nations. The most prevalent middle-income countries in editorial boards were Brazil (n = 184, 4.26%), India (n = 150, 3.47%), Turkey (n = 42, 0.97%), and Iran (n = 36, 0.83%). Only 40 (1.07%) editorial board members of Q1 journals were affiliated with non-high-income nations, most belonging to India (n = 28, 70%). Journals from middle-income nations had a statistically significant lower prevalence in the first- and second-quartile ranking (P < 0.001) and a higher proportion of open-access policies (P = 0.019).

CONCLUSIONS: A clear underrepresentation of low- to middle-income nations was observed in ophthalmology journals. Promoting editorial diversity and minimizing the possibility of editorial bias could lead to greater exposure to real-world data from resource-constrained settings.

TRANSLATIONAL RELEVANCE: The documented underrepresentation of low- to middle-income nations in ophthalmology journals highlights the importance of promoting diversity and inclusion.

ABSTRACT

The continuous genetic evolution of SARS-CoV-2 resulting in the immune escape variant of concern (VoC) Omicron poses a challenge to rapid and accurate diagnosis of infection, especially in high-risk groups such as healthcare workers. We performed a clinical study to determine the diagnostic accuracy and robustness of a second-generation rapid antigen test compared to a first-generation rapid antigen test with an RT-qPCR-based assay as gold standard, for early detection of infections with SARS-CoV-2 Omicron VoC. A total of 428 healthcare workers with COVID-19-associated symptoms or during routine testing participated in the study and completed a questionnaire on infection-associated symptoms, previous SARS-CoV-2 infections, and vaccination status. All participants performed a second- and first-generation rapid antigen test on the day of presentation and repeated the test 2 days later, and a diagnostic SARS-CoV-2 RT-qPCR assay was performed. qPCR-confirmed SARS-CoV-2 infections (n = 104) with Omicron VoC (BA.2, BA.4, BA.5) were detected by the first-generation rapid antigen test with a sensitivity of 83.7% (95% CI 75.12%-90.18%), whereas the second-generation rapid antigen test performed with a sensitivity of 89.4% (95% CI 81.9%-94.6%). Increased sensitivity of the second-generation rapid antigen test led to earlier detection of SARS-CoV-2 infection, while lower test sensitivity of the first-generation rapid antigen test was compensated by repeated testing 2 days later. Moreover, direct in vitro comparison revealed a lower limit of detection for the second-generation rapid antigen test for isolates of currently circulating Omicron sub-lineages BA.5.2, BQ.1, and XBB.1. IMPORTANCE The results from this study demonstrate the usefulness of a second-generation rapid antigen test for early detection of infection with the SARS-CoV-2 Omicron variant of concern (VoC) and reveal a higher sensitivity to detect immune escape Omicron VoCs compared to a first-generation rapid antigen test (89.4% vs 83.7%) in the high-risk group of healthcare workers.

ABSTRACT

BACKGROUND: The treatment response of primary central nervous system lymphomas (PCNSLs) is mainly evaluated using postcontrast T1-weighted imaging (T1WI). Because poorly enhanced lesions may contain residual tumors, the combination of evaluation methods will potentially improve the accuracy of determining treatment effectiveness. In this study, we evaluated the usefulness of diffusion-weighted imaging (DWI) in predicting recurrence among patients with PCNSL who achieved complete response (CR)/unconfirmed CR (CRu).

METHODS: Fifty-four patients newly diagnosed with PCNSL who were treated at our institution and achieved CR/CRu at the end of treatment were included in this study. The patients were divided into two groups according to the presence or absence of residual DWI hyperintense signal at the tumor site at the end of treatment. Kaplan-Meier analysis was performed to analyze the median overall survival (OS) and progression-free survival (PFS).

RESULTS: The mean age of the 54 patients was 66.4 ± 13.3 years. The induction therapies were HD-MTX in 20 patients, R-MPV in 29 patients, and other chemotherapies in five patients. Radiotherapy was performed in 35 patients, high-dose cytarabine therapy in 14 patients, and autologous hematopoietic stem cell transplantation in one patient, and of the 54 patients, 10 had no consolidation therapy. The residual DWI hyperintense signal sign was observed in 18 patients. The R-MPV regimen was statistically associated with a lower rate of residual DWI hyperintense signal (p = 0.0453). The median PFS was statistically shorter in the residual DWI hyperintense signal group than in the non-residual DWI hyperintense signal group (14.0 months vs. 85.1 months) (p < 0.0001, log-rank test).

CONCLUSION: A residual DWI hyperintense signal at the end of treatment was statistically associated with shorter PFS. Among patients who achieved CR/CRu evaluated based on postcontrast T1WI, DWI could be a valuable additional sequence to predict the early recurrence of PCNSL.

ABSTRACT

PURPOSE: There are only limited data on drug utilization patterns in pediatric inpatients, especially on general wards. The aim of the study was to describe prescribing patterns and their associations with prescribing errors in a university children’s hospital in the German-speaking part of Switzerland.

METHOD: This was a subanalysis of a retrospective single-center observational study. Patient characteristics and drug use of 489 patients with 2693 drug prescriptions were associated with prescribing errors. Drugs were categorized by the Anatomic Therapeutic Chemical Classification System (ATC), patients were categorized by age group according to European Medicines Agency guidelines, and prescribing errors were analyzed by type [Pharmaceutical Care Network Europe (PCNE) classification] and severity of error [adapted National Coordinating Council for Medication Error Reporting (NCC MERP) index].

RESULTS: The most frequently prescribed ATC classes were nervous system (N) (42.6%), alimentary system (A) (15.6%), and anti-infective drugs (J) (10.7%). Eighty-two percent of patients were prescribed an analgesic. Most drugs were prescribed for oral (47%) or intravenous (32%) administration, but the rectal route was also frequent (10%). The most frequently prescribed drugs were paracetamol, metamizole, and ibuprofen. The high number of metamizole prescriptions (37% of patients were prescribed metamizole) is typical for German-speaking countries. Older pediatric patients were prescribed more drugs than younger patients. A statistically significant difference was found in the rate of potentially harmful errors across age groups and for gender; children between 2 and 11 years had a higher rate of potentially harmful errors than infants under 2 years (p = 0.029) and female patients had a higher rate of potentially harmful errors than male patients (p = 0.023). Recurring errors were encountered with certain drugs (nalbuphine, cefazolin).

CONCLUSIONS: Our study provides insight into prescribing patterns on pediatric general wards in a university children’s hospital in Switzerland and highlights some areas for future research. Especially, the higher risk for prescribing errors among female pediatric patients needs further investigation.

ABSTRACT

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. Previous studies have suggested that metabolites may play a pivotal mediating role in the progression of phenotypic variations. Although several metabolites had been identified as potential markers for PCOS, the relationship between blood metabolites and PCOS was not comprehensively explored. Previously, Pickrell et al. designed a robust approach to infer evidence of a causal relationship between different phenotypes using independently putative causal SNPs. Our previous paper extended this approach to make it more suitable for cases where only a few independently putative causal SNPs were identified to be significantly associated with the phenotypes (i.e., metabolites). When the most significant SNPs in each independent locus (the independent lead SNPs) with p-values of < 1 × 10^-5 were used, 3 metabolites (2-tetradecenoyl carnitine, threitol, 1-docosahexaenoylglycerophosphocholine) causally influencing PCOS and 2 metabolites (asparagine and phenyllactate) influenced by PCOS were identified, (relative likelihood r < 0.01). Under a less stringent threshold of r < 0.05, 7 metabolites (trans-4-hydroxyproline, glutaroyl carnitine, stachydrine, undecanoate, 7-Hoca, N-acetylalanine and 2-hydroxyisobutyrate) were identified. Taken together, this study can provide novel insights into the pathophysiological mechanisms underlying PCOS; whether these metabolites can serve as biomarkers to predict PCOS in clinical practice warrants further investigations.

ABSTRACT

INTRODUCTION: Comparisons of Janus kinase inhibitors (JAKi) for treatment of rheumatoid arthritis in patients with inadequate response to biologic disease-modifying anti-rheumatic drugs are lacking. We assessed the relative efficacy and safety of four JAKi (tofacitinib, baricitinib, upadacitinib, and filgotinib) in this context.

METHOD: We performed an adjusted indirect comparison (IC) of randomized clinical trials using Bucher’s method with an IC and mixed calculator. Endpoints were Disease Activity Score C-reactive protein (DAS28-CRP) and American College of Rheumatology-20 (ACR20). Equivalence was assessed using the equivalent therapeutic alternatives (ETA) guidelines.

RESULTS: We included four of 133 potentially relevant studies. IC showed no statistically significant differences between the four JAKi regarding DAS28-CRP < 3.2. Results were similar in terms of ACR20 except for tofacitinib showing lower efficacy than upadacitinib (RAR -18.4% [IC95% -33.4 to -3.5], p=0.0157). Statistically significant differences were related to the relevant difference for tofacitinib in both endpoints. Despite no statistical differences for baricitinib, we observed a probably clinically relevant difference regarding DAS28-CRP. Probably clinically relevant differences were found for tofacitinib vs. upadacitinib in both endpoints, and for baricitinib vs. upadacitinib in DAS28-CRP. Safety, drug-drug interactions, and convenience considerations did not modify the result of therapeutic equivalence assessment based on efficacy data.

CONCLUSIONS: In conclusion, our results show that filgotinib and upadacitinib are ETA. Baricitinib and upadacitinib are also ETA due to a lack of clear differences and for showing superiority over placebo. The results for tofacitinib and upadacitinib show some inconsistency and more data are needed. Key Points • To date, neither a head-to-head comparison nor an indirect comparison between the Janus kinase inhibitors has been performed in patients with rheumatoid arthritis and an inadequate response to biologic disease-modifying anti-rheumatic drugs. • We performed an adjusted indirect comparison that included randomized clinical trials of tofacitinib, baricitinib, upadacitinib, and filgotinib to assess their equivalence in this scenario. • Our results show that baricitinib and filgotinib are equivalent therapeutic alternatives compared to upadacitinib. However, there is some inconsistency in the results of tofacitinib in front of upadacitinib.

ABSTRACT

Seroma formation is one of the important postoperative problems in inguinal hernia surgery, especially after scrotal hernia surgery. The present study aimed to present primarily the incidence of seroma after reduction and transection of the hernia sac in endo-laparoscopic scrotal hernia repair, and secondarily the results of early postoperative complications. Patients were divided into two groups TAPP and TEP. These groups were also divided into transection and reduction subgroups. In the reduction group, the hernia sac was completely dissected and pulled to the peritoneal area, while in the transection group, the neck of the hernia sac was cut by ligating, and its distal part was fixed to the posterior abdominal wall. The groups were compared, and data were analyzed. The reduction was performed in 13 (43.33%) of the 30 patients included in the study, and transection in 17 (56.67%). Seroma developed in 2 (15.38%) of the reduction group and 7 (41.18%) of the transection group. There was no statistical difference between the groups (p = 0.229). Cord and testicular complications were seen in 6 (20%) patients, 5 (38.46%) in the reduction group, and 1 (5.88%) in the transection group. No statistical difference was detected between the groups (p = 0.061). Although not statistically significant, seroma was more common in transection, while cord and testicular complications were more common in reduction. If dissection of the hernia sac is difficult, the complete reduction should not be insisted on, and the neck of the sac should be transection by ligating, and its distal part should be fixed to the posterior abdominal wall.
