ABSTRACT
Post radical prostatectomy (RP) erectile dysfunction and incontinence impacts quality of life for patients. In an objective to hasten the recovery of these functional outcomes, human placental derived allografts laid on neurovascular bundles (NVB) have been investigated. These grafts include amniotic membranes (AM) chorionic membranes (CM) or umbilical cord (UC) allografts. A literature review performed using the MeSH terms “AMNION” OR “CHORION” OR “AMNIOTIC MEMBRANE” OR “UMBILICAL CORD” AND “PROSTATE CANCER” from no specified start date, to April 2022. 163 articles were retrieved, with 149 articles excluded. 14 articles were eligible and analysed. 5 articles were included in this review for an analysis on comparative outcomes. The average return to potency was statistically significant in the intervention groups. Positive surgical margin (PSM) rates showed a higher rate in the control groups. BCR was observed at a lower rate in the interventional group. This review reveals a benefit from human placental allograft’s ability to hasten post RP functional recovery, without impacting oncological control.

ABSTRACT
INTRODUCTION AND HYPOTHESIS: This study aims to determine whether the use of preoperative transdermal scopolamine is associated with an increased risk of postoperative urinary retention in urogynecologic surgeries.
METHODS: This is a retrospective chart review study of women who underwent surgery between January 1, 2018, and December 31, 2020. Patients who received a scopolamine patch versus those who did not were compared using demographic and perioperative variables utilizing Pearson’s chi-squared test and t-test of Wilcoxon rank-sum. A logistic regression was performed to evaluate the effect of scopolamine on the patients’ postoperative voiding trial results, controlling for confounders. P-value < 0.05 was considered statistically significant.
RESULTS: A total of 449 women underwent a vaginal or laparoscopic hysterectomy, midurethral sling placement, uterosacral or sacrospinous ligament suspension, sacrocolpopexy, anterior/posterior colporrhaphy, or other urogynecologic surgeries with 109 (24.2%) having received transdermal scopolamine. A significantly higher number of women with preoperative scopolamine [n = 50 (45.9%)] failed their voiding trial compared to those without scopolamine [n = 100 (29.4%), p = 0.0016]. The adjusted model yielded an odds ratio of 1.75 (95% CI: 1.08-2.85) of a failed voiding trial in the scopolamine group. When comparing the odds of failing voiding trial by surgery type, those with a midurethral sling placed during surgery had an adjusted odds ratio of 3.12 (95% CI: 2.01-4.87), as compared to those without a midurethral sling.
CONCLUSIONS: Use of a transdermal scopolamine patch for nausea and vomiting prophylaxis is associated with increased risk of postoperative urinary retention across all urogynecologic surgeries.

ABSTRACT
We previously found an association of insulin resistance (IR) with plasma xanthine oxidoreductase (XOR) activity in a cross-sectional study. However, whether IR induces increased XOR activity has not been elucidated. This retrospective longitudinal observational study included 347 participants (173 males, 174 females) who underwent annual health examinations and were medication naïve. Homeostasis model assessment of IR (HOMA-IR) index, and physical and laboratory measurements were determined at the baseline. At baseline and 12-month follow-up examinations, plasma XOR activity was determined using our novel assay based on [13C2,15N2] xanthine and liquid chromatography/triple quadrupole mass spectrometry. Subjects with IR, defined as HOMA-IR index ≥ 1.7 (n = 92), exhibited significantly (p < 0.001) higher plasma XOR activity levels than those without IR (n = 255), with an increase in that activity seen in 180 (51.9%) after 12 months. Multivariable linear and logistic regression analyses showed that IR, but not BMI or waist circumference, at baseline was significantly associated with plasma XOR activity (β = 0.094, p = 0.033) and increased plasma XOR activity over the 12-month period (odds ratio, 1.986; 95% confidence interval, 1.048-3.761; p = 0.035), after adjustments for various clinical parameters, including plasma XOR activity at baseline. These results suggest that IR induces increased plasma XOR activity in a manner independent of adiposity.

ABSTRACT
PURPOSE: Petroclival meningioma (PM) is a challenging neuro oncology case and stereotactic radiosurgery (SRS) is proposed as one treatment option. This systematic review aimed to examine the role of SRS in treating PM cases.
METHODS: We constructed a systematic review using the PRISMA guidelines using peer-reviewed English literature until 16 February 2022 from EuroPMC and PubMed. We used the terms petroclival meningioma, clival meningioma, apex petrous meningioma, spheno petroclival meningioma, stereotactic radiosurgery, radiosurgery, CyberKnife, Gamma Knife, linear accelerator, LINAC, and radiotherapy.
RESULTS: 10 out of 266 studies were chosen for this systematic review, two of which are case reports. The study comprised 719 patients, 73.7% of whom were female (n = 530) and had a median age of 56.99 years (18-90 years). At the time of diagnosis, the median tumor volume was 6.07 cm3 (0.13-64.9 cm3). The tumors were frequently located near the petroclival junction (83.6%, n = 598). Following SRS, the median follow-up was 64.52 months (3-252 months). 46.5% of 719 PMs exhibited a decrease in tumor size. 46% and 7.5% showed no change and increase in tumor volume, respectively. At the last radiographic follow-up (7-21.2 years), tumor control with a median of 98.8% (85-100%). Complications occurred in 6% of patients, with hydrocephalus (2.2%) as the prevalent complication. The use of SRS as a primary treatment for petroclival cases was not associated with increased complication rate RR 0.62 (95% CI [0.11, 3.59], p = 0.59) but statistically correlated with clinical failure clinical failure RR 0.56 (95% CI [0.32, 0.98], p = 0.04).
CONCLUSIONS: We found a low number of complications following SRS intervention and has been effectively controlling tumor progression.

ABSTRACT
OBJECTIVE: It has been described that thymoglobulin could increase the risk of infections and malignancies, in comparison to basiliximab. Leukopenia and thrombocytopenia are also more common within the first days after transplantation among thymoglobulin patients. Our objective was to analyze bleeding complications in this subset of patients.
MATERIAL AND METHODS: Bleeding complications were evaluated among 515 renal transplants carried out at our institution between 2012 and 2018. We compared patients treated with thymoglobulin (Group 1, N=91) with those treated with basiliximab (Group 2, N=424).
RESULTS: We found differences in platelet decrease: 95,142.2 (55,339.6) in Group 1 and 52,364.3 (69,116.6) in Group 2 (P=0.001), number of patients with severe thrombocytopenia (<75,000/mm3) (20.8% vs. 3.7%, P=0.001), number of blood units transfused (3.25 (0.572) vs. 2.2 (0.191, P=0.028) and percentage of patients that required surgery due to bleeding (18.2% vs. 7.7%, P=0.046). In a multiple lineal regression multivariable analysis (dependent variable was number of blood units transfused), only age [OR 0.037, 95% CI (0.003-0.070)] and type of immunosuppression [OR 1.592, 95% CI (1.38-2.84)] showed statistical significance.
CONCLUSIONS: The use of thymoglobulin in the perioperative transplantation period could increase bleeding complications. In our series, in the group of patients with thymoglobulin, severe thrombocytopenia was 6 times more frequent, and active bleeding that required surgery was also 2.5 times more frequent. One way to continue with the use of this immunosuppression agent, might be to adjust the dose instead of discontinuing it. The use of thymoglobulin should be a factor to consider in the postoperative period of these patients.

ABSTRACT
The most accepted procedures as conversion for poor weight changes after sleeve gastrectomy (SG), are malabsorptive surgeries. This study was designed to evaluate the 5-year outcomes of One Anastomosis Gastric Bypass (OAGB) following SG due to weight loss failure and weight regain. From September 2014 to January 2017, totally 23 patients with a history of SG conversion to OAGB in terms of weight loss failure or weight regain who had completed their 5-year follow-ups were studied. Some obesity related co-morbidities containing type-2 diabetes (DM), hypertension (HTN), dyslipidemia, obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) were also investigated at 1, 2, 3 and 5 years after conversional surgery. All cases had remission/improvement in DM, DLP, HTN and OSA 1 year after conversional OAGB. Analysis showed statistically significant (P < 0.001) change in trend of BMI. Mean BMI before conversional surgery, at 1, 2, 3and 5 years were 46.3 ± 10.4, 34.5 ± 8.5, 34.1 ± 8.6, 35.7 ± 8.7 and 37.5 ± 11.6, respectively. Mean percent excess weight loss (%EWL) at 1, 2, 3 and 5 years was 51.6 ± 11.0, 52.9 ± 13.1, 45.5 ± 16.4 and 41.0 ± 18.0, respectively. Mean percent total weight loss (%TWL) at 1, 2, 3 and 5 years was 26.6 ± 5.9, 27.4 ± 7.2, 23.9 ± 9.2 and 20.9 ± 9.3, respectively. OAGB is an effective conversional procedure for insufficient weight loss and weight regain following failed SG and lead to satisfactory changes in obesity associated medical problems. The optimal weight loss results are obtained at 2-year follow-ups and these effects are then reduced.

ABSTRACT
AIM: To examine the relationship between catheter tip location and catheter dysfunction in the context of tunnelled central venous catheters (CVCs) for haemodialysis.
MATERIALS AND METHODS: This was a retrospective study of 993 haemodialysis patients who underwent insertion of tunnelled CVCs of step-tip design via the right internal jugular vein (IJV). Based on intra-procedural radiographs, the catheter tip was characterised as being in the superior vena cava (SVC), cavo-atrial junction (CAJ), or deep right atrium (DRA). Patients were tracked for 90 days post-procedure for complications resulting in catheter replacement, and these were compared between cohorts. Statistical analysis was performed with Pearson’s chi-square and Fisher’s exact tests for categorical variables and two-sample t-test and one-way analysis of variance (ANOVA) for continuous variables.
RESULTS: Ninety-five patients (9.6%) experienced catheter dysfunction necessitating replacement within 90 days of insertion. Tip location in SVC was associated with lower occurrence of catheter dysfunction (1.9%) as compared with the CAJ (8%) and DRA (11%; p=0.049). Catheter replacement due to other complications (catheter-associated bacteraemia, cuff dislodgement, exit-site infection, external catheter damage) showed no statistically significant relation to location of the CVC tip.
CONCLUSION: When utilising tunnelled CVCs with a step-tip design inserted via the right IJV, location of the catheter tip in the SVC is associated with reduced occurrence of catheter dysfunction as compared to either the CAJ or DRA.

ABSTRACT
OBJECTIVE: The purpose of this study was to explore the context and mechanisms by which the first set of Milestones impacted the processes of the Clinical Competency Committee, how programs have incorporated the Milestones into their program, and to understand more about the resident perspective in order to improve Orthopedic Surgery Milestones.
DESIGN, SETTING, AND PARTICIPANTS: In 2020 all 201 accredited orthopedic surgery residency programs were invited to participate in qualitative telephone interviews to assess their experience with the Milestones and complete a supplemental online survey about their Clinical Competency Committee. Participants were comprised of a self-selected sample and complemented by a purposeful sample to ensure a breadth of perspectives. Interview data were analyzed using template analysis. Survey data were analyzed with descriptive statistics.
RESULTS: Interviews were completed with 101 individuals from 47 programs (23% of all programs). The two overarching themes were implementation and impact of Milestones. Subthemes within implementation were substantial variability in approaches to Milestone use in curriculum and assessment, faculty development, and methods to introduce residents to the Milestones assessment framework. The large number of subcompetencies created a significant burden for almost all programs. The structure of the Milestones was also viewed as poorly aligned with the variable design of rotation schedules across programs. Milestones have the potential to offer valuable feedback for trainees and programs overall.
CONCLUSIONS/APPLICATION: While some benefits were noted and most programs appreciated the intent, the structure and design of the initial set of orthopedic surgery Milestones created substantial challenges for these programs. The results of this study helped guide a revision of the Orthopedic Surgery Milestones. These results can also be used by program leadership to encourage reflection around past, current, and future utilization of the Milestones framework. Further research will be needed to determine the impact of the revision on programs.

ABSTRACT
OBJECTIVES: To evaluate and compare image quality and radiation dose between the helical and wide-volume scans to determine the protocol that provides a lower radiation dose without loss in image quality.
METHODS: The study was prospectively conducted on consented adult patients that presented for routine brain CT. Image quality and radiation dose were compared between the helical and wide-volume scans on the Toshiba 160-slice Aquilion Prime CT scanner. The volume computed tomography dose index (CTDIvol) and dose length product (DLP) for each scan mode were collected and compared. Image quality was quantitatively and qualitatively evaluated using the unenhanced brain CT images. The data were analysed using a statistical package for social sciences (SPSS) software version 20 for both the descriptive and inferential statistics. A significant difference in image quality and radiation dose between the helical and wide-volume scans was determined based on a p-value of <0.05.
RESULTS: A total of 54 participants were included, with two groups of 27 participants. The CTDIvol and DLP values were significantly p < 0.05 higher in the helical scan (CTDIvol: 65 mGy; DLP: 1597 mGy.cm) compared to the wide-volume scan (CTDIvol: 54 mGy; DLP: 1133 mGy.cm). The grey and white matters show a better signal-to-noise ratio (SNR) for the helical scan. Meanwhile, the contrast-to-noise ratio (CNR) was significantly p < 0.05 higher in the wide-volume scan. The results from the visual grading methods were compared and showed superior image quality in helical over the wide-volume scan.
CONCLUSION: Wide-volume provides a lower dose compared to helical and therefore, could be adopted as the routine protocol for brain CT for in house dose optimisation. Where clinical conditions warrant the need for a helical scan, the protocol should be optimised in line with the as low as reasonable achievable (ALARA) principle.
