RESUMO
PURPOSE: To evaluate if self-administered bladder neuromodulation with transcutaneous tibial nerve stimulation can safely replace overactive bladder medications in people with spinal cord injury. MATERIALS AND METHODS: We performed a 3-month, randomized, investigator-blinded, tibial nerve stimulation vs sham-control trial in adults with spinal cord injury and neurogenic bladder performing intermittent catheterization and taking overactive bladder medications. The primary outcome was a reduction in bladder medications while maintaining stable bladder symptoms and quality of life based on pre-post Neurogenic Bladder Symptom Score and the Incontinence-QOL questionnaire, respectively. Secondary outcomes included changes in pre-post cystometrogram, 2-day voiding diaries, and an anticholinergic medication side effect survey. RESULTS: Fifty people consented to the study, with 42 completing the trial. No dropouts were due to stimulation issues. All baseline demographics and surveys were comparable at baseline. Cystometrogram parameters were also comparable at baseline, except the stimulation group had a higher proportion of loss of bladder compliance compared to the control group. At the end of the trial, a significantly greater percentage of the tibial nerve stimulation group were able to reduce medications (95% v 68%), by a 26.2% difference in medication reduction (95% confidence interval 1.17%-51.2%). Function and quality of life surveys and cystometrograms at the end of the trial were alike between groups. Transcutaneous tibial nerve stimulation satisfaction surveys and adherence to protocol were high. CONCLUSIONS: In people with chronic spinal cord injury performing intermittent catheterization, transcutaneous tibial nerve stimulation can be an option to reduce or replace overactive bladder medications.
RESUMO
Objective: To determine the magnitude of the perioperative costs associated with robotic gastrectomy (RG). Background: A robotic surgery platform has a high implementation cost and requires maintenance costs; however, whether the overall cost of RG, including all perioperative costs, is higher than conventional open gastrectomy (OG) remains unknown. Methods: Patients who underwent a major gastrectomy during February 2018 through December 2021 were retrospectively identified. We calculated the perioperative costs of RG and OG and compared them overall as well as in different phases, including intraoperative costs and 30-day postsurgery inpatient and outpatient costs. We investigated factors potentially associated with high cost and estimated the likelihood of RG to reduce overall cost under a Bayesian framework. All cost data were converted to ratios to the average cost of all operations performed at our center in year FY2021. Results: We identified 119 patients who underwent gastrectomy. The incidence of postoperative complications (Clavien-Dindo >IIIa; RG, 10% vs OG, 13%) did not significantly differ between approaches. The median length of stay was 3 days shorter for RG versus OG (4 vs 7 days, P < 0.001). Intraoperative cost ratios were significantly higher for RG (RG, 2.6 vs OG, 1.7; P < 0.001). However, postoperative hospitalization cost ratios were significantly lower for RG (RG, 2.8 vs OG, 3.9; P < 0.001). Total perioperative cost ratios were similar between groups (RG, 6.1 vs OG, 6.4; P = 0.534). The multiple Bayesian generalized linear analysis showed RG had 76.5% posterior probability of overall perioperative cost reduction (adjusted risk ratio of 0.95; 95% credible interval, 0.85-1.07). Conclusions: Despite increased intraoperative costs, total perioperative costs in the RG group were similar to those in the OG group because of reduced postoperative hospitalization costs.
RESUMO
OBJECTIVE: To identify urinary biomarkers that can distinguish active renal involvement in Lupus Nephritis (LN), a severe manifestation of systemic lupus erythematosus (SLE). METHODS: Urine from 117 subjects, comprised of inactive SLE, active non-renal lupus, active LN, and healthy controls, were subjected to Proximity Extension Assay (PEA) based comprehensive proteomics followed by ELISA validation in an independent, ethnically diverse cohort. Proteomic data is also cross-referenced to renal transcriptomic data to elucidate cellular origins of biomarkers. RESULTS: Systems biology analyses revealed progressive activation of cytokine signaling, chemokine activity and coagulation pathways, with worsening renal disease. In addition to validating 30 previously reported biomarkers, this study uncovers several novel candidates. Following ELISA validation in an independent cohort of different ethnicity, the six most discriminatory biomarkers for active LN were urinary ICAM-2, FABP4, FASLG, IGFBP-2, SELE and TNFSF13B/BAFF, with ROC AUC ≥80%, with most correlating strongly with clinical disease activity. Transcriptomic analyses of LN kidneys mapped the likely origin of these proteins to intra-renal myeloid cells (CXCL16, IL-1RT2, TNFSF13B/BAFF), T/NK cells (FASLG), leukocytes (ICAM2) and endothelial cells (SELE). CONCLUSION: In addition to confirming the diagnostic potential of urine ALCAM, CD163, MCP1, SELL, ICAM1, VCAM1, NGAL and TWEAK for active LN, this study adds urine ICAM-2, FABP4, FASLG, IGFBP-2, SELE, and TNFSF13B/BAFF as additional markers that warrant systematic validation in larger cross-sectional and longitudinal cohorts.

OBJECTIVES: To describe and analyze the trends of pediatric sinusitis cases from 2018 to 2022 across the country utilizing the Pediatric Hospital Information System (PHIS) database focusing on volumes, socioeconomics, and severity of cases. STUDY DESIGN: Retrospective Cohort Study. METHODS: A retrospective cohort study using the Pediatric Health Information System (PHIS) database, which consists of 50 children's hospitals was performed. Regions were defined according to PHIS guidelines. We evaluated percentage of sinusitis cases demographic and socioeconomic information and subgrouped by region throughout 2018-2022. RESULTS: In all regions there were a greater number of sinusitis cases post-COVID compared to pre-COVID, with notable increases in major and extreme severity. The years 2020 and 2021 saw a decrease in total sinusitis cases in all locations. Both surgical intervention and severity of sinusitis were significant factors affecting length of stay. Age and severity were the most significant predictors regarding the odds of having sinus surgery. Age and insurance type were significant predictors of severity, with increasing age and government insurance associated with higher odds of major or extreme severity of sinusitis. CONCLUSIONS: There appears to be a trend of both increased number and worsening severity of acute sinusitis cases in the post-COVID era compared to pre-COVID. There was a decrease in cases in 2020-2021 during the pandemic, consistent with trends of other communicable diseases.
