ABSTRACT

BACKGROUND: With the rise in bariatric surgeries, conversions for issues like poor weight loss or reflux are becoming more common. Gastric bypass is a standard solution, but as robotic use grows, its advantage over laparoscopy remains in question.

OBJECTIVE: Compare the short and long-term outcomes of robotic versus laparoscopic sleeve conversion to Roux-en-Y gastric bypass (RYGB) surgeries.

METHODS: We conducted a retrospective analysis analyzing patients’ demographics, comorbidities, reasons for conversion, preoperative body mass index (BMI), and perioperative metrics (operative time, blood loss, hospital stay). We compared surgical outcomes, including early complications, rehospitalization, reintervention, weight loss, and resolution of comorbidities, between the robotic and laparoscopic approaches.

RESULTS: This cohort included 126 patients who underwent revisional surgery from sleeve gastrectomy to gastric bypass surgery. Out of which 27 underwent laparoscopic approaches and 99 robotic approaches. The mean age of patients was 52.5 (±11.6), and the mean pre-RYGB BMI was 36.1 (±7.1). Most patients were female (87.3%, n = 110), with 72.2% white. Robotic approach had a significantly shorter operative time than laparoscopic approach 184.1 vs 215.5 minutes, with P-value < .001, respectively. Other outcomes did not show any statistical significance between the two groups. However, the late reoperation rate revealed a significant difference, with 29.6% in the laparoscopic group required additional surgical intervention, whereas only 13.1% in the robotic group with P-value .041, suggesting advantage for the robotic approach.

CONCLUSION: Both techniques demonstrated similar complication rates. Notably, the robotic approach resulted in shorter operating times and fewer late reoperations. Further research is necessary to strengthen our findings.

ABSTRACT

BACKGROUND & AIMS: Aging and alcohol misuse independently alter monocyte (MO) and macrophage (MØ) function, leading to impaired antimicrobial responses. However, how alcohol misuse contributes to impaired MO/MØ function during aging remains unclear.

METHODS: We compared the transcriptomes of MOs and MØs from alcohol-modulated niches (liver, brain, and bone marrow [BM]) in young (3-month-old) and old (20-24-month-old) female C57BL/6N mice (n = 4-6 per group). Statistical significance was determined using two-way ANOVA.

RESULTS: MO/MØ transcriptomes showed unique organ-specific responses to aging and alcohol. Aging elicited a common deregulation of pathogen-responsive pathways, while alcohol misuse commonly inhibited IFN signaling in the aged populations. Our studies on intercellular communication using ligand-receptor interactions revealed that BM MOs were the least communicative and liver MØs were the most communicative. Alcohol misuse specifically increased MO/MØ communication in aging. We also identified and validated specific pathways driving inter-organ MO/MØ crosstalk in alcohol misuse during aging, including APOE-TREM2 signaling from the liver to microglia and the NRXN2 and SPP1 pathways.

CONCLUSION: Our results provide a unique insight into the heterogeneity of the MO/MØ transcriptome and define the inter-organ crosstalk between BM, liver, and brain during aging and alcohol misuse.

IMPACT AND IMPLICATIONS: Aging and alcohol misuse are linked to immune dysfunction, systemic inflammation, and altered innate immune responses. Here, we examined monocyte/macrophage responses in the liver, brain, and bone marrow of young and aged mice under alcohol exposure at the transcriptomic level. We observed that aging and alcohol predominantly elicited organ-specific changes in gene expression, with minimal overlap between the monocyte/macrophage populations across different tissues. However, aging commonly upregulated pathogen response pathways while alcohol misuse inhibited interferon signaling. We also assessed cell-cell communication by analyzing ligand-receptor expression in the different monocyte/macrophage populations and identified candidate molecules (APOE, TREM2, NRXN2, SPP1) from the top pathways guiding inter-organ signaling specifically in aging and alcohol misuse. Our findings have generated a unique repository and provide novel insights on how aging and alcohol impact tissue-specific monocytes/macrophages and their crosstalk.

ABSTRACT

BACKGROUND: Mitochondria and immune function play pivotal roles in the pathogenesis of gestational diabetes mellitus (GDM). However, the intricate molecular mechanisms underlying their involvement remain elusive. Therefore, this study aimed to elucidate the interaction between mitochondria-related genes (MRGs) and immune-related genes (IRGs) in GDM.

METHODS: In this study, GDM-related datasets (GSE103552, GSE154414, and GSE173193) were integrated along with MRGs and IRGs. Differential expression analysis was conducted on GSE103552 to identify differentially expressed genes (DEGs), which were then intersected with MRGs and IRGs. Correlations among the intersection genes were evaluated, and those with statistical significance and strong correlation were selected as candidate genes. Three machine learning algorithms were subsequently applied to further refine the selection of signature genes. The optimal model was determined, and genes within this model were designated as signature genes. Expression levels of these genes were then examined, and those showing significant differences and consistent trends between GDM and control groups in both GSE103552 and GSE154414 datasets were identified as hub genes. Further analyses included chromosomal and subcellular localization, enrichment, regulatory mechanism, and drug prediction analyses of hub genes. Key cell types were analyzed in GSE173193. Finally, the expression of hub genes was validated by reverse transcription quantitative polymerase chain reaction (RT-qPCR).

RESULTS: Comprehensive analysis identified MRPL15, MRPL22, and MRPS18C emerged as pivotal hub genes, each showing significantly lower expression levels in the GDM group. Chromosomal localization revealed MRPS18C on chromosome 4, MRPL22 on chromosome 5, and MRPL15 on chromosome 8. Subcellular distribution analysis indicated that MRPL15 and MRPL22 were predominantly localized in the nucleus, whereas MRPS18C was mainly cytoplasmic. Enrichment analysis showed that spliceosome, proteasome, Parkinson disease, and ribosome pathways were enriched by the hub genes. Regulatory analysis revealed that YY1 regulated MRPS18C and MRPL22, ARID3A regulated MRPS18C and MRPL15, and FOXC1 regulated MRPL22 and MRPL15. Finally, results of RT-qPCR results confirmed that MRPL15, MRPL22, and MRPS18C were significantly downregulated in the GDM group.

CONCLUSION: Our findings highlight the significance of MRPL15, MRPL22, MRPS18C, monocytes, and villous cytotrophoblast cells in GDM. These insights provide valuable implications for the diagnosis and potential therapeutic interventions targeting of GDM.

ABSTRACT

INTRODUCTION: Follow-up data in breast cancer is essential and forms the basis for survival metrics and key statistical measures related to morbidity and mortality. Standard practice classifies any woman who does not engage in reviews/follow-up as “lost to follow-up (LTFU),” effectively excluding her from further analysis and disregarding her data. This study aims to evaluate patterns and predictors of LTFU among women with non-metastatic breast cancer.

DESIGN: This is a single-center prospective cohort study involving women diagnosed with non-metastatic breast cancer between 2017 and 2018. The study will follow a three-phase approach. In Phase I, 5-year follow-up data will be collected retrospectively through hospital records and electronic medical records (EMRs) up to 2024. In Phase II, patients identified as LTFU will be contacted using phone, SMS, or email to assess health status and update follow-up data. Informed consent will be obtained during outreach. In Phase III, patients who respond will be asked about reasons for missed follow-up visits, including barriers related to logistics, finance, awareness, or physician advice. Data will be analyzed using descriptive statistics, logistic regression, and thematic analysis.

OBJECTIVES: To determine the proportion of patients who are lost-to-follow-up at 5 years, identify factors associated with LTFU, and explore patient-reported barriers to follow-up in a public sector cancer care setting.

DISCUSSION: This study uses a mixed-methods approach, combining quantitative tracking with qualitative insights, with the aim of understanding patient retention and long-term oncology care. This study will provide real-world evidence on follow-up adherence and its determinants in a high-volume, resource-constrained oncology setting. The study is registered with ClinicalTrials.gov (Trial identifier: NCT06927102).

ABSTRACT

BACKGROUND: Prostate cancer remains a significant public health challenge, an early detection with prostate-specific antigen (PSA) testing and biparametric MRI (bpMRI) can improve outcomes. However, participation hinges on motivational, psychological, and logistical factors. This study examines the motivational profile of men in the ProstaPilot study to guide strategies to increase uptake of state-of-the-art prostate cancer screening programs.

METHODS: The ProstaPilot study enrolled 423 men who underwent both PSA testing and bpMRI of the prostate. Positive results (PSA ≥ 3 μg/L or PI-RADS 4-5 lesions) were referred for further urological examination and biopsy. Using an exploratory correlational design, 360 participants completed a detailed questionnaire. Motivational factors were extracted via Principal Component Analysis (PCA) with Oblimin rotation. Perceptions of prostate cancer risk, severity, and prevention were rated on 1-10 scales (10 = most positive).

RESULTS: PCA identified four motivational factors explaining 55.6% of variance: (1) concerns about screening (e.g., unnecessary surgery, loss of control); (2) perceived benefits of early detection; (3) social motivation (e.g., contributing to research, role modeling); and (4) barriers (e.g., logistics, embarrassment). Over half (51.1%) had not considered screening before ProstaPilot; others decided over varying timeframes. Participants showed high awareness of prostate cancer and valued early detection, rating screening effectiveness 9.55 ± 0.98 and trust in healthcare professionals 9.6 ± 1.0. Social/familial influences were moderate. Satisfaction was high: likelihood to recommend 9.45 ± 1.22; confidence in continuing participation 9.9 ± 0.39.

CONCLUSION: Highly motivated participants were marked by strong knowledge of prostate cancer screening, trust in healthcare providers, supportive social context, and high personal commitment. These findings support personalized, socially supportive, educational strategies to increase uptake of state-of-the-art screening.

CLINICAL TRIAL REGISTRATION: The study was registered on September 21, 2024, with the identifier number NCT05603351.

ABSTRACT

BACKGROUND: Minimal Change Disease (MCD) / Focal Segmental Glomerulosclerosis (FSGS) are leading causes of adult nephrotic syndrome. Roughly half of patients need long-term immunosuppression for steroid dependence or relapse, but traditional drugs carry substantial adverse effects. Rituximab (RTX) depletes CD20⁺ B cells and reduces anti-podocyte antibodies; pediatric data are encouraging, yet direct adult evidence-especially between treatment-naïve and relapsed patients-remains scarce.

METHODS: This study enrolled 82 patients with MCD/FSGS diagnosed between 2020 and 2023, divided into the RTX group (24 patients, 9 treatment-naïve and 15 relapsed) and the glucocorticoid group (58 patients). The RTX group received standard-dose RTX (375 mg/m² weekly for 4 weeks), while the glucocorticoid group was treated with prednisone (1 mg/kg/day). Outcomes were compared using t-tests, χ²/Fisher, logistic regression, and Kaplan-Meier analyses.

RESULTS: The overall remission rates were 100% in the RTX group and 98.3% in the glucocorticoid group (P=0.876), but the RTX group had a significantly higher eGFR at the last follow-up (124.25 vs 109.00 mL/min/1.73 m², P=0.019). A statistically significant intergroup difference was also observed, with complete remission achieved in 89.5% of MCD patients versus 40% of FSGS patients (P< 0.05). In relapsed patients treated with RTX, prednisone dosage decreased from 34.0±15.7 mg/day to 7.7±7.8 mg/day (P< 0.001), annual relapse frequency dropped from 1.0 to 0 episodes/year (P=0.001), and 40% of patients completely discontinued glucocorticoids. The Complete Remission rate in treatment-naïve patients (88.9%) was higher than in relapsed patients (73.3%), but the difference was not statistically significant. No independent predictors of RTX efficacy were identified, and no severe infections or allergic reactions were observed.

CONCLUSION: RTX equals glucocorticoids in podocytopathy, cuts steroid use and relapse, improves long-term kidney survival, and is safe. Treatment-naïve patients may choose RTX upfront to avoid steroid side effects; relapsed patients can taper and stop steroids. However, due to the limited sample size, these results should be interpreted with caution. Larger trials must confirm its long-term efficacy and ESRD protection.

ABSTRACT

Autoimmune mechanisms are associated with both congestive heart failure (CHF) and atrial fibrillation (AF). Optic neuritis (ON) is known to elevate the risk of systemic autoimmune disorders. However, it remains uncertain whether ON serves as a risk factor for CHF and AF. This study aimed to investigate the association between ON and the risk of CHF and AF in a nationwide, population-based cohort. The research utilized data from Korea’s National Health Insurance Service, analyzing 15,587 patients newly diagnosed with ON and 77,935 age- and sex-matched controls from 2010 to 2017. Factors of demographics, medical history, lifestyle, and lab results were considered. CHF and AF incidences were identified through ICD-10 codes and analyzed using Cox regression models adjusted for confounders. During the 4-year follow-up, CHF and AF were diagnosed in 3.39 and 0.86% of participants, respectively. ON patients showed higher risks of CHF [hazard ratio (HR) = 1.341] and AF (HR = 1.215) after adjusting for potential confounders. Notably, stronger associations for CHF risk were found in patients younger than 50 years and those in the lowest income quartile. The findings provide compelling evidence of an independent association between ON and increased risks of CHF and AF, especially in younger individuals, suggesting a role of autoimmune processes in ON under these cardiovascular conditions. The study highlights the need for early cardiac evaluation in ON patients and suggests that timely interventions could improve prognosis. Further research is necessary to understand the pathophysiological links between ON and cardiovascular disorders.

ABSTRACT

INTRODUCTION: Existing studies suggest vitamin D (VD) deficiency links to adverse pregnancy outcomes in singletons; however, its association with specific adverse outcomes and neonatal health in twin pregnancies remains unclear. This study aimed to explore the relationship between maternal VD levels and maternal and neonatal outcomes in twin pregnancies.

METHODS: This study collected VD levels, pregnancy conditions, and neonatal anthropometry from 324 twin pregnancies. Peripheral blood serum was collected from mothers in mid- and late pregnancy to measure VD concentrations. Logistic models assessed VD’s association with pregnancy complications and neonatal anthropometry. The restricted cubic splines (RCS) method was used to estimate the risk threshold for spontaneous preterm birth (sPTB). Accounting for sample size and based on the Akaike (AIC) and Bayesian (BIC) information criteria, three knots were placed at the 10th, 50th, and 90th percentiles of the VD distribution. Missing data were handled using sensitivity analyses-including both optimistic and conservative assumptions-and multiple imputation methods.

RESULTS: Among all the participants, the mean mid-pregnancy VD concentration was 25.08 ± 8.31 ng/mL, with 25.6% having sufficient levels, 46.9% insufficient, and 27.5% deficient. Mid-pregnancy VD deficiency independently predicted sPTB (OR: 2.19; 95% CI: 1.07-4.50; p = 0.033). The RCS revealed an L-shaped VD-sPTB risk relationship. Each 1 ng/mL VD decrease increased sPTB risk by 14.94% (OR = 0.87). No statistically significant evidence was found between rising VD levels from mid- to late pregnancy and reduced sPTB risk vs. persistent low gestational VD levels. The analysis did not provide evidence for a statistically significant association between maternal mid-pregnancy VD levels and the incidence of hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM), iatrogenic preterm birth (iPTB), or neonatal birth weight (all p > 0.05). In contrast, chorionicity (p = 0.004), HDP (p = 0.046), and neonatal sex (p = 0.021) were significant determinants of birth weight.

CONCLUSIONS: In twin pregnancies, maintaining adequate VD levels during mid-pregnancy represents a critical preventive window for reducing sPTB. For women with deficiency at this stage, the timing of supplementation may be more critical than dose. Although maternal VD status shows no significant association with neonatal anthropometry, the continued monitoring and optimization of VD levels throughout pregnancy remain essential for maternal-neonatal health.

ABSTRACT

OBJECTIVE: To study the potential correlation between pregnancy weight gain (WG) and the incidence of gestational diabetes mellitus (GDM).

METHODS: Clinical records of women with singleton pregnancies who had a first visit at Fujian Maternity and Child Health Hospital before 14 weeks and delivered after 28 weeks were retrospectively analyzed. Based on the first trimester WG, the participants were grouped as inadequate (iWG-F), adequate (aWG-F), and excessive (eWG-F) WG groups. The outcomes of interest included GDM, gestational hypertension, preeclampsia, small for gestational age (SGA), LGA, low birth weight (LBW), preterm birth, macrosomia, primarily cesarean section (CS), and admission to the neonatal intensive care unit (NICU). Statistical analyses included logistic regression, interaction, and mediation analyses.

RESULTS: A total of 16,824 pregnancies were analyzed. GDM incidences of the iWG-F, aWG-F, and eWG-F groups were 24.53%, 26.62%, and 29.46%, respectively, with a statistically significant difference (p < 0.001). Multivariable logistic regression showed that inadequate WG correlated with reduced risk of GDM when adjusted for pre-pregnancy body mass index (PPBMI) of below 18.5 kg/m² [adjusted odds ratio (aOR) = 0.68], and 18.5-23.9 kg/m² (aOR = 0.88). The association of inadequate WG and reduced risk of GDM persisted when adjusted for age <30.5 years (aOR = 0.81), fasting glucose ≥4.9 mmol/L (aOR = 0.74), triglycerides <1.4 mmol/L (aOR = 0.84), and HDL <1.63 mmol/L (aOR = 0.85). WG in the second trimester was associated with GDM (β = -0.003, p = 0.036) and partially mediated the effect of eWG-F (-3.7% of the total effect). WG before OGTT showed no association with GDM.

CONCLUSION: First trimester WG is significantly associated with the occurrence of GDM. In contrast, there is only a minimal association between second-trimester and pre-OGTT WG and the risk of GDM. Inadequate first-trimester weight gain reduces GDM risk, especially in younger women, women with normal or low PPBMI, elevated fasting glucose, and low HDL or triglycerides, without increasing abnormal neonatal birth weight. Early pregnancy represents a critical window for GDM prevention. Minimal weight gain during this period may be a feasible and acceptable approach to reducing GDM risk.

ABSTRACT

BACKGROUND: Coffee is a globally consumed beverage. However, the impairments associated with its excessive use remain under-recognized. There is currently no standardized measurement for coffee use disorder based on DSM-5 application. This study describes the development and psychometric properties of the Coffee Use Disorder and Coffee Addiction Scale (CUDCAS)-a self-report tool developed specifically for this purpose.

METHODS: A cross-sectional survey was designed and delivered to 523 participants. Items from CUDCAS (11 items with reference cluster) indicate substance use disorder criteria taken from the DSM-5 and were rated on a three point Likert scale and used descriptive statistics; internal consistency (Cronbach’s α and McDonald’s ω); exploratory/confirmatory factor analysis (EFA, CFA); item response theory (IRT), and correlations with caffeine consumption, insomnia (AIS) and anxiety symptoms (GAD-7) were also examined.

RESULTS: CUDCAS was found to be a very reliable (α and ω = 0.86) measure of coffee use disorder symptoms. CFA results supported the unidimensional factor structure of the CUDCAS and the overall model fit was good (CFI = 0.92, TLI = 0.90, RMSEA = 0.07, SRMR = 0.04). The IRT analyses further demonstrated an appropriate distribution of item difficulties, measurement of item precision and subsequently, CUDCAS as an overall measurement of coffee use disorder that is responsive to coffee consumption. CUDCAS also demonstrated significant correlations with caffeine consumption (r = 0.54), insomnia (r = 0.37), and anxiety (r = 0.32), respectively, for construct validity.

CONCLUSIONS: The findings suggest that the CUDCAS is a reliable and valid tool to assess the symptoms of coffee use disorder, and the current results provide support for its use in research and clinical settings.
