Psychological Health of Surgeons in a Time of COVID-19: A Global Survey.

OBJECTIVE: To assess the degree of psychological impact among surgical providers during the COVID-19 pandemic. SUMMARY OF BACKGROUND DATA: The COVID-19 pandemic has extensively impacted global healthcare systems. We hypothesized that the degree of psychological impact would be higher for surgical providers deployed for COVID-19 work, certain surgical specialties, and for those who knew of someone diagnosed with, or who died, of COVID-19. METHODS: We conducted a global web-based survey to investigate the psychological impact of COVID-19. The primary outcomes were the depression anxiety stress scale-21 and Impact of Event Scale-Revised scores. RESULTS: A total of 4283 participants from 101 countries responded. 32.8%, 30.8%, 25.9%, and 24.0% screened positive for depression, anxiety, stress, and PTSD respectively. Respondents who knew someone who died of COVID-19 were more likely to screen positive for depression, anxiety, stress, and PTSD (OR 1.3, 1.6, 1.4, 1.7 respectively, all P < 0.05). Respondents who knew of someone diagnosed with COVID-19 were more likely to screen positive for depression, stress, and PTSD (OR 1.2, 1.2, and 1.3 respectively, all P < 0.05). Surgical specialties that operated in the head and neck region had higher psychological distress among its surgeons. Deployment for COVID- 19-related work was not associated with increased psychological distress. CONCLUSIONS: The COVID-19 pandemic may have a mental health legacy outlasting its course. The long-term impact of this ongoing traumatic event underscores the importance of longitudinal mental health care for healthcare personnel, with particular attention to those who know of someone diagnosed with, or who died of COVID-19.

Personality differences between internal medicine and surgical residents in an Asian population.

PURPOSE: Personality traits often have an impact on the way individuals relate to each other as colleagues and the patients we treat. It is often perceived that distinct personality exist between different specialties and may help predict success during one's training and career. METHODS: Objective of the study was to compare the personality between surgical and medical residents. Thirty-five medical residents and 35 surgical residents completed the Revised NEO Personality Inventory, a validated measure of personality traits. A score was generated for each of the 5 major character traits namely: neuroticism(N), extraversion(E), openness(O), conscientiousness(C), agreeableness(A). Each of these traits were subdivided into 6 component facets. This was compared with sociodemographic characteristics. RESULTS: Medical residents displayed higher scores in the area of overall Agreeableness, with a mean score of 47.4 vs 40.5. Within Agreeableness facets, medical residents also displayed higher scores of straightforwardness, altruism and modesty. Surgical residents displayed higher scores in terms of overall Extraversion (52.4 vs 45.4). Within the Extraversion facets, surgical residents were also more assertive and excitement-seeking. There was no difference in the overall neuroticism domain; however, within the neuroticism facets, surgical residents had statistically higher mean scores in angry hostility and impulsiveness. Gender stratification did not result in any statistically significant difference. CONCLUSION: There are fundamental differences between personalities of medical and surgical residents. Detailed analysis of each individual's data could be useful, with proper assistance and coaching, for residents in learning more about their personalities and how these impact their clinical practice. This can be beneficial in future career counselling and the development of a more holistic medical practitioner.

Convective Water Vapour Energy Ablation (Rezum®) versus Prostatic Urethral Lift (Urolift®); A 2-Year Prospective Study.

Introduction To compare the clinical outcomes and complication rates of Convective Water Vapour Energy Ablation (Rezum®) and Prostatic Urethral Lift (Urolift®). To identify predictive factors for treatment failures in both treatments. Materials & Methods Prospective clinico-epidemiological data of patients who underwent Urolift® or Rezum® in a single institution for Benign Prostatic Hyperplasia (BPH) was collected. The choice of intervention depended on the preference of the patients after patient-centric discussions. Results From October 2019 to October 2022, 86 patients underwent Rezum® and 62 patients underwent Urolift®. Rezum® involved a longer indwelling catheter duration (12.38±5.548 versus 1.39±3.010 days, p<0.001) compared to Urolift®. Rezum® was associated with more complications compared to Urolift® (36 (41.9%) versus 10 (16.1%) cases, p<0.001). Rezum® had more cases of hematuria (17 (19.8%) versus 4 (6.5%) cases (p=0.022)) and urinary tract infections (27 (31.4%) versus 3 (4.8%) cases, p<0.001)), compared to Urolift®. There were no significant differences in Clavien-Dindo Grade 3-5 complications between the interventions. Urolift® was associated with higher re-operation rates (5 (8.1%) versus 0 (0%) cases, p=0.010) compared Rezum®. Rezum® had higher anti-cholinergic usage rates compared to Urolift® post-operation (22 (25.6%) versus 8 (12.9%) cases, p=0.024). Both interventions showed improvement in International Prostate Symptom Score (IPSS), Quality of Life score, and peak velocity flow over the 2 years with no significant difference between the two. Based on receiver operating characteristic curve, pre-operation IPSS ≥ 16 had 95.7% sensitivity and 38.4% specificity to predict the probability of treatment failures after the interventions. Conclusions There was no difference in clinical outcomes of patients who underwent Rezum® and Urolift®. However, patients who had undergone Rezum® faced more minor complications and more required anti-cholinergic medications. Lastly, physicians should note that patients with IPSS≥16 would unlikely benefit from either intervention.

Implementation of a Ureteric Colic Telemedicine Service: A Mixed Methods Quality Improvement Study.

OBJECTIVE: To assess the effectiveness of a telemedicine service for ureteric colic patients in reducing the number of unnecessary face-to-face consultations and shortening waiting time for appointments. METHODS: A telemedicine workflow was implemented as a quality improvement study using the Plan-Do-Study-Act method. All patients presenting with ureteric colic without high-risk features of fever, severe pain, and hydronephrosis, were recruited, and face-to-face appointments to review scan results were replaced with phone consultations. Data were prospectively collected over 3 years (January 2017 to December 2019). Patient outcomes including the reduction in face-to-face review visits, time to review, reattendance and intervention rates, were tracked in an interrupted time-series analysis, and qualitative feedback was obtained from patients and clinicians. RESULTS: Around 53.2% of patients presenting with ureteric colic were recruited into the telemedicine workflow. A total of 465 patients (46.2%) had normal scan results and 250 patients (24.9%) did not attend their scan appointments, hence reducing the number of face-to-face consultations by 71.1%. A total of 230 patients (22.9%) required subsequent follow-up with urology, while 61 patients (6.1%) were referred to other specialties. Mean (SD) time to review was 30.0 (6.2) days, 6-month intervention rate was 3.4% (n = 34) and unplanned reattendance rate was 3.2% (n = 32). Around 93.1% of patients reported satisfaction with the service. CONCLUSION: The ureteric colic telemedicine service successfully and sustainably reduced the number of face-to-face consultations and time to review without compromising on patient safety. The availability of this telemedicine service has become even more important in helping us provide care to patients with ureteric colic in the current COVID-19 pandemic.

A Small Group Randomized Double-Blind Placebo-Controlled Study to Evaluate the Efficacy of Daily Pentoxifylline in the Management of Patients With Erectile Dysfunction with Suboptimal Treatment Response to Sildenafil.

INTRODUCTION: Several studies have reaffirmed the use of regular pentoxifylline therapy in increasing the penile brachial pressure index in men affected by erectile dysfunction when compared to placebo. AIM: The aim of this study was to evaluate the efficacy of pentoxifylline as an adjunctive treatment for patients with erectile dysfunction. METHODS: This study was a single center, prospective, randomized, double-blind, placebo-controlled trial. Subjects were recruited between April 2014 and November 2016 from the National University Hospital, Singapore. The combination therapy group was given pentoxifylline 400 mg thrice daily orally and the monotherapy group was given placebo capsules thrice daily orally. Both groups continued their on-demand 100 mg sildenafil. The treatment duration was 8 weeks. Efficacy was measured via the International Index of Erectile Function (IIEF-5) questionnaire at the eighth week. Differences in mean IIEF-5 score and the domains of the IIEF at 8 weeks between the 2 treatment groups were compared using independent sample t-test. MAIN OUTCOME MEASURE: Baseline IIEF-5 and the IIEF-15 score vs post-therapy IIEF-5 and the IIEF-15 score. RESULTS: 50 patients were randomized into 2 groups. Patients in the 2 groups were comparable in terms of the demographic and clinical characteristics, comorbidities, and baseline IIEF-5 scores. The mean IIEF-5 score post-therapy of the combination therapy group vs the monotherapy group was 14.11 and 14.87, respectively. There was no significant difference between the outcomes of these 2 groups (unadjusted mean difference -0.76; 95% CI -4.01 to 2.49; P = .641) and the outcomes are the same even after adjusting for baseline IIEF-5 scores. There was a significant improvement in the "overall satisfaction" portion of the IIEF score for the combination therapy group as compared to the monotherapy group (unadjusted mean difference 0.12; 95% CI -1.49 to 1.25) and even after adjustment for baseline scores (adjusted mean difference 1.11; 95% CI 0.10 to 2.12; P = .032) the improvement is significant. CONCLUSION: Our trial suggests that the use of combination therapy does not improve the management of patients compared to monotherapy. Law YXT, Tai BC, Tan YQ et al.

Multiphoton Microscopic Study of the Renal Cell Carcinoma Pseudocapsule: Implications for Tumour Enucleation.

OBJECTIVE: To utilize Multiphoton Microscopy (MPM) as a novel imaging technique to characterize and quantify collagen at the Renal Cell Carcinoma Pseudocapsule, to assess for both intra-tumoral and inter-tumoral variation of collagen characteristics. MPM combines Second Harmonic Generation and Two Photon Excitation Fluorescence to image extracellular matrix architecture. METHODS: Twenty partial nephrectomy specimen tissues were retrieved, cut into 5-micron sections, mounted on slides and deparaffinized. The pseudocapsules (PCs) were imaged with 2X and 20X objective at selected Regions of Interest. Corresponding clinical information was retrieved. PC thickness was determined. Collagen parameters measured included quantification by the Collagen Area Ratio, and qualitative measurements by the Collagen Fiber Density and Collagen Reticulation Index. RESULTS: The boundaries between tumor, PC and normal renal parenchyma were distinguished by MPM without need for staining. In the thickest areas of the PC, collagen content and density were quantitatively higher compared to the thinnest areas. Median Collagen Area Ratio was higher in the thickest compared to the thinnest areas of the PC (P = .01). Clear Cell RCC specimens had a consistently higher Collagen Fiber Density in both the thickest and thinnest areas compared to non-Clear Cell RCC specimens (P = .02). CONCLUSIONS: We demonstrated the ability of MPM to quantify collagen characteristics of PCs without fluorescent labeling. Tumor enucleation for Renal Cell Carcinoma along its PC remains debatable with regards to oncological safety. Even with a complete and intact PC, the PC is not a homogenous structure, and varies in its thickness and its collagen characteristics within, and between tumors.
