ABSTRACT

OBJECTIVE: This study aims to compare the efficacy of intra-articular injections of hyaluronic acid (HA), platelet-rich plasma (PRP), and platelet-rich fibrin (PRF) for treating temporomandibular disorders (TMDs) and summarize their mechanisms of action.

METHODS: Randomized controlled trials (RCTs) published until November 13, 2021, were identified using electronic and manual searches. Each study was evaluated for the risk of bias using the Cochrane risk of bias tool. The studies found via searches were categorized by follow-up time (1, 3, or 6 months). Evidence quality was graded according to the GRADE system.

RESULTS: Twelve RCTs were included that involved 421 patients with TMD. The network meta-analysis showed that all treatment groups improved compared to the placebo groups in terms of pain and maximal mouth opening (MMO). For pain evaluated via the visual analog scale, PRF exhibited better analgesic effects than PRP or HA after 1 and 3 months. PRP appeared to be more effective than PRF was after 6 months but there were no statistically significant differences between the two. For MMO, the effect of PRP was superior to those of PRF and HA after 1 month. However, after 3 and 6 months, PRF provided more encouraging results in improving MMO.

CONCLUSION: PRP and PRF exhibited similar short-term efficacy in treating TMD, while PRF was more advantageous in terms of long-term efficacy. Therefore, PRF was recommended for treating TMD.

ABSTRACT

BACKGROUND: Evidence indicates that Nigeria’s high maternal mortality rate is attributable primarily to events that occur during the intrapartum period. This study determines the effectiveness of multifaceted interventions in improving the quality of intrapartum care in Nigeria’s referral hospitals.

METHODS: Data collected through an exit interview with 752 women who received intrapartum care in intervention and control hospitals were analyzed. The interventions were designed to improve the quality indicators in the WHO recommendations for positive childbirth and assessed using 12 quality indicators. Univariate, bivariate, Poisson, and logistic regression analyses were used to compare twelve quality indicators at intervention and control hospitals.

RESULTS: The interventions showed a 6% increase in composite score of quality of care indicators at intervention compared with control hospitals. Five signal functions of intrapartum care assessed were significantly (< 0.001) better at intervention hospitals. Quality scores for segments of intervention periods compared to baseline were higher at intervention than in control hospitals.

CONCLUSIONS: We conclude that multiple interventions that address various components of the quality of intrapartum care in Nigeria’s referral hospitals have demonstrated effectiveness. The interventions improved five of ten quality indicators. We believe that this approach to developing interventions based on formative research is important, but a process of integrating the implementation activities with the normal maternal health delivery processes in the hospitals will enhance the effectiveness of this approach.

TRIAL REGISTRATION: The study was registered at the Nigeria Clinical Trials Registry.

ABSTRACT

OBJECTIVE: To compare the surgical outcomes and complications of boys who underwent double-face onlay-tube-onlay transverse preputial island flap (DFOTO) one-stage repair vs. two-stage repair for proximal hypospadias.

STUDY DESIGN: Males with proximal hypospadias who underwent DFOTO or two-stage repair at a single institution from 2008 to 2021 were identified. Patients who had prior hypospadias surgery were excluded. Outcomes were surgical complications, number of surgical procedures, operative time, and post-operative uroflowmetry results.

RESULTS: Fifty-three males who underwent DFOTO and 39 who underwent two-stage repair were included. Median age at surgery was 1.1 years (IQR 0.83-1.6) and median follow-up was 3.0 years (IQR 1.2-6.8). Although not statistically significant, the DFOTO group had higher rates of urethrocutaneous fistula (30% vs. 15%, p = 0.10), urethral stricture (15% vs. 3%, p = 0.07) and urethral diverticulum (8% vs. 3%, p = 0.39). Although the unplanned re-operation rate was higher in DFOTO (58% vs. 33%, p = 0.02), the mean number of procedures and median total surgical time were lower in DFOTO (1.8 ± 0.9 vs. 2.4 ± 0.8, p = 0.0004; 337 min [IQR 278-460] vs. 468 min [IQR 400-563], p = 0.008). There were no significant differences between groups for mean peak flow rates and post void residuals.

CONCLUSIONS: In males who underwent DFOTO, 42% achieved completion of their proximal hypospadias repair with one operation, while the remainder had largely minor complications. Accounting for reoperation rates, the mean number of procedures per patient was lower in the DFOTO group. Comparable results can be achieved with both techniques; the risks of higher unplanned operation rates in the DFOTO group should be considered with the benefit of fewer total procedures.

ABSTRACT

INTRODUCTION: Although most pediatric urologists do not perform clamp circumcisions in boys older than 3 months or heavier than 5.5 kg, there are no universally accepted guidelines on the optimal patient age or weight.

OBJECTIVE: To compare outcomes of office circumcision within and outside these traditional patient parameters.

METHODS: This is a retrospective review of circumcisions performed by a single surgeon from 2019 to 2022. Demographics reviewed include age and weight at time of circumcision, gestational weeks at birth, as well as post-procedure: bleeding, planned and unplanned visits, adhesions/concealment, and interventions related to the circumcision. “Active Bleeding” was defined as bleeding occurring after discharge requiring intervention with pressure, sutures, or cautery. “All Bleeding” included Active Bleeding, and cases where bleeding was controlled at home with pressure, stopped by the time of arrival at clinic or emergency department, and immediate bleeding after circumcision controlled before discharge.

RESULTS: During the study period, 773 Gomco circumcisions were performed. A total of 603 patients (78%) had post-procedure evaluation 2 weeks after circumcision. 574 patients (74%) were less than 5.5 kg and 199 (26%) over. Only age corrected for gestation was used in the study: 658 (85%) were younger than 3 months and 115 (15%) older. There was no significant difference in Active Bleeding based on weight (p = 0.3819) or age (p = 0.2798), and no difference in All Bleeding based on weight (p = 0.2072). There was a significant difference (p = 0.0258) in All Bleeding based on age. There was also a significant difference in unexpected visits based on weight (p = 0.0258) and age (p = 0.0131). With regards to adhesions, there was no statistical significant differences when comparing weight or age. However, older and heavier boys had significantly more concealment (5% vs <1%).

DISCUSSION: Our study showed Active Bleeding rates 0.5-0.9% higher in the older and heavier group, although the difference did not reach statistical significance. We found a significantly increased rate of unexpected post-procedure visits of around 3.5-4.7% in those patients older than 3 months and heavier than 5.5 kg. Also, post -procedure concealment was significantly increased in the older and heavier boys. Modifications of the dressing for high risk groups could reduce the risk of bleeding, and efforts on pre-circumcision education of the families might ameliorate unexpected visits. Exlcuding patients with hidden penis or performing penoscrotal skin tacking at the time of the gomco circumcision could decrease concealment rates in the higher risk patients.

CONCLUSIONS: Gomco clamp circumcision is safe in patients over 5.5 kg and older than 3 months, with a less than 1% higher risk of bleeding, which in the current study was controlled without the need for general anesthesia or transfusions. Broadening the inclusion criteria for office clamp circumcisions could reduce costs and make the procedure available to patients who cannot afford to have the surgery under general anesthesia.

ABSTRACT

BACKGROUND: Bariatric surgery is an effective intervention that causes a series of metabolic changes related to inflammatory processes; however, the variation of biomarkers related to these processes is not entirely understood. Our objective was to investigate the variation of modulation and expression of biomarkers associated with inflammation in patients who underwent bariatric surgery.

METHODS: We searched the MEDLINE (via PubMed), EMBASE (via Elsevier), Cochrane Central Register of Controlled Trials, Latin American and Caribbean Literature on Health Sciences (via virtual health library), Cumulative Index to Nursing and Allied Health Literature (via EBSCO), Web of Science core collection, and Scopus (via Elsevier) databases, and the gray literature was examined from inception to January 2022. Three pairs of reviewers performed data screening, extraction, and quality assessment independently. Meta-analysis with random effects models was used for general, subgroup, and sensitivity analyses. The I² statistic was used to assess heterogeneity between studies.

RESULTS: In total, 96 articles were included in this systematic review; of these, 87 studies met the criteria for the meta-analysis, involving 3,533 participants. Five biomarkers were included in the meta-analysis (tumor necrosis factor alpha; interleukin 6; leptin; interleukin 1 beta, and lipopolysaccharides). Only leptin showed a significant decrease in the first month after surgery (mean difference -20.71; [95% confidence interval: -28.10 to -13.32, P < .0001; I² = 66.7%), with moderate heterogeneity. The 12 months after surgery showed a significant decrease in tumor necrosis factor alpha (mean difference -0.89; [95% confidence interval: -1.37 to -0.42], P = .0002; I² = 94.7%), interleukin 6 (mean difference -1.62; [95% confidence interval: -1.95 to -1.29], P < .0001; I² = 94.9%), leptin (mean difference -28.63; [95% confidence interval: -34.02 to -23.25], P < .0001; I² = 92.7%), and interleukin 1 beta (mean difference -2.46; [95% confidence interval: -4.23 to -0.68], P = .006; I² = 98.3%), all with high heterogeneity. The type of surgery did not show significant differences for the biomarkers at the first month and 12 months, and the results have not changed with high-quality studies. In the 12-month measurement, variations in tumor necrosis factor alpha and leptin were associated with body mass index.

CONCLUSION: The findings of this meta-analysis suggest that Roux-en-Y gastric bypass and sleeve gastrectomy bariatric surgeries are associated with a significant reduction in leptin at 1 month after bariatric surgical intervention and tumor necrosis factor alpha, leptin, and interleukin 1 beta after 12 months.

ABSTRACT

OBJECTIVE: Examine the applicant experience after introduction of program signaling for the 2023 obstetrics and gynecology (OBGYN) residency application cycle.

DESIGN: Responses to an online survey of OBGYN applicants participating in the 2023 match who participated in residency program signaling were compared to responses from a similar survey conducted in 2022. Demographic information included personal and academic background and how applicants and advisors communicated with programs. Numbers of applications and interviews, second look visits, away rotations, manner of contact, and timing of communication was compared. Statistical analysis included ANOVA for interval data, and χ2 and Kruskal-Wallis tests for categorical data.

RESULTS: A total of 711 of 2631 (27%) applicants responded in 2022 and 606 of 2492 (24.3%) responded in 2023. Approximately 2/3 of gold signals and 1/3 of silver signals led to an interview. There was no change in number of applications or interviews per applicant, but there was a broader distribution of interviews per applicant in 2023. Applicants in 2023 were less likely to engage in preinterview communication or do an away rotation to indicate interest in a program. There was decreased communication between applicants and programs after signaling was introduced. Informal communication continued to differ by racial and medical school background. Applicants from DO programs and international medical graduates (IMG) had more communication with programs than MD applicants but received fewer interview invitations. Fewer Black and Latin(x)/Hispanic applicants had faculty reach out to residency programs on their behalf compared to White and Asian applicants. There were differences in the number of interviews received based on racial and ethnic identity.

CONCLUSIONS: In the first year after implementation of program signaling, there was a decrease in preinterview communication and a broader distribution of interviews among applicants. Further efforts to create standard means of program communication may help to begin leveling the uneven playing field for applicants.

ABSTRACT

BACKGROUND: The objective is to study vocal outcomes following laser-assisted sulcus release (LASR), having documented the length and depth of the sulcus intraoperatively. LASR performed for superficial and deep sulci were included.

STUDY DESIGN: Retrospective, observational.

METHODS: The preoperative and 3-month postoperative and post voice-therapy Voice Handicap Index 10 (VHI), Grade-Roughness-Breathiness-Asthenia-Strain of the voice (GRBAS), Maximum Phonation Time (MPT), Fundamental Frequency (FO), and stroboscopy findings were noted retrospectively from our voice clinic records of LASR patients. Intraoperative sulci length and depth details were noted from records. Patients with coexisting lesions, surgically tackled, were excluded.

RESULTS: In a total of 14 patients, 21 superficial sulci and eight deep sulci were operated by LASR. The average preoperative VHI improved from 25.3 to 9.9, GRBAS from 10.6 to 3.5, and MPT from 7.6 to 12.3 seconds. The preoperative average FO was 235.9 Hz in 12 patients (no pick-up in two) with a postoperative 248.4 Hz. Using the Mann-Whitney U test, we found a statistically significant improvement in MPT, VHI, and GRBAS of the patients. There was no significant improvement in the FO of the patients. There was no postoperative voice deterioration in any patient. A preoperative phonatory gap was found in all patients, which postoperatively was absent in 10, markedly decreased in three, present in one with stroboscopy revealing an improvement in mucosal wave amplitude in 13 patients. In four patients with deep bilateral sulci where the LASR had been ligament deep, VHI improved from 26 to 13.3, GRBAS from 12 to 6.5, and MPT from 4.3 to 9.5 seconds. Using the Mann-Whitney U test, all three parameters were significantly improved.

CONCLUSION: A statistically significant vocal improvement in VHI, GRBAS, and MPT was observed at 3 months, in superficial and deep sulci, operated by LASR. LASR is a simple, quick, and easily replicable surgery. Larger multi-centric studies with long-term follow-up are recommended.

ABSTRACT

BACKGROUND: This multi-institutional, observational study examined whether the outcomes after peritoneal dialysis (PD) catheter placement in Japan meet the audit criteria of the International Society for Peritoneal Dialysis (ISPD) guideline and identified factors affecting technique survival and perioperative complications.

METHODS: Adult patients who underwent first PD catheter placement for end-stage kidney disease between April 2019 and March 2021 were followed until PD withdrawal, kidney transplantation, transfer to other facilities, death, 1 year after PD start or March 2022, whichever came first. Primary outcomes were time to catheter patency failure and technique failure, and perioperative infectious complications within 30 days of catheter placement. Secondary outcomes were perioperative complications. Appropriate statistical analyses were performed to identify factors associated with the outcomes of interest.

RESULTS: Of the total 409 patients, 8 who underwent the embedded catheter technique did not have externalised catheters. Of the 401 remaining patients, catheter patency failure occurred in 25 (6.2%). Technical failure at 12 months after PD catheter placement calculated from cumulative incidence function was 15.3%. On Cox proportional hazards model analysis, serum albumin (hazard ratio (HR) 0.44; 95% confidence interval (CI) 0.27-0.70) and straight type catheter (HR 2.14; 95% CI 1.24-3.69) were the independent risk factors for technique failure. On logistic regression analysis, diabetes mellitus was the only independent risk factor for perioperative infectious complications (odds ratio 2.70, 95% CI 1.30-5.58). The occurrence rate of perioperative complications generally met the audit criteria of the ISPD guidelines.

CONCLUSION: PD catheter placement in Japan was proven to be safe and appropriate.

ABSTRACT

PURPOSE OF THE ARTICLE: Health professions graduate students have experienced substantial increases in stress and anxiety in recent years. This can result in decreased academic performance, poor retention, and burnout. Interventions to help students cope are therefore a critical need for academic institutions. The current study sought to demonstrate the effectiveness of a brief multimodal intervention in reducing student distress.

METHOD: The study was a randomised controlled design that evaluated a brief intervention of cognitive-behavioural therapy, mindfulness, and healthy lifestyle choices. The Depression Anxiety Stress Scale-21 was administered to participants at baseline and two post-intervention time points. Control participants did not participate in any intervention. Participants were recruited from graduate students in first-year classes within the School of Health Professions at UT Southwestern Medical Center.

RESULTS: Analysis revealed an overall mild to moderate decline in Depression Anxiety Stress Scale-21 total scores over three assessment periods for both treatment and control groups, with no statistical differences noted between groups; however, the treatment group’s scores declined approximately 6 weeks before the control participants’ scores declined.

CONCLUSION: The pattern of change in the two groups suggests that our intervention facilitated the reduction in student anxiety more quickly than would have occurred normally and with sustained results.

ABSTRACT

We present a GC-MS metabolomics workflow for analyzing metabolites in urine samples infected with schistosomiasis. Schistosomiasis, a neglected tropical disease, affects 85% of the global population, with the majority residing in Sub-Saharan Africa. The workflow utilized in this study involved the utilization of the AMDIS freeware, Metab R for pre-processing, and multivariate statistical classification through partial least squares-discriminant analysis (PLS-DA). This classification aimed to categorize volatile metabolites found in urine samples from humans infected with schistosomiasis. All samples were collected from individuals in Botswana. A solid-phase microextraction-fused silica fiber was used to adsorb volatile metabolites from the urine samples and inserted into the GC-MS injection port for data acquisition. The acquired data were then subjected to AMDIS auto-deconvolution, Metab R pre-processing, and statistical evaluation for metabolite mining. A total of 12 metabolites, including 3-chloropropionic acid and heptadecyl ester with an AMDIS match factor of 96% at an approximated amount of 0.35% and cyclohexylamine with an AMDIS match factor of 100% and approximated amount of 0.39%, were identified. PLS-DA was used for the classification of the metabolites. The method showed good sensitivity and specificity as indicated by the receiver operating characteristic measured by the areas under the curves. Results indicated that metabolomics is a useful tool for mining metabolites because of the variance in metabolite composition of infected and non-infected urine samples.
