Implications of technological advancement of surgery in low and middle-income countries' a narrative review.

Countries that are striving to keep pace with emerging technologies in surgical practices and still not able to cope with exemplary international standards are in dire need of resources to build and strengthen their healthcare system. This review focusses on the impeding factors that hinder in adaptation of advanced technology and machinery in the health care industry. Considering the immense potential for current surgical technologies to transform the delivery of healthcare, their implementation in LMICs confronts considerable challenges due to lack of infrastructure, human capital and inadequate resources. To address these difficulties, various entities, including healthcare institutions, government and non-governmental organisations, and foreign partners, must work together. Building capacity through intended education and training initiatives, building infrastructure, and collaborative partnerships are critical for overcoming hurdles to effective deployment of surgical technology in low-income communities of the world.

Global health education in high-income countries: confronting coloniality and power asymmetry.

Contemporary global health education is overwhelmingly skewed towards high-income countries (HICs). HIC-based global health curricula largely ignore colonial origins of global health to the detriment of all stakeholders, including trainees and affected community members of low- and middle-income countries. Using the Consortium of Universities for Global Health's Global Health Education Competencies Tool-Kit, we analyse the current structure and content of global health curricula in HICs. We identify two major areas in global health education that demand attention: (1) the use of a competency-based education framework and (2) the shortcomings of curricular content. We propose actionable changes that challenge current power asymmetries in global health education.

Art Heals: Randomized Controlled Study Investigating the Effect of a Dedicated In-house Art Gallery on the Recovery of Patients After Major Oncologic Surgery.

INTRODUCTION: We sought to investigate the effect of exposure to a dedicated art gallery during the perioperative period on the recovery of patients undergoing major oncologic procedures. METHODS: Eighty patients were randomized into 2 arms; standard of care versus exposure to art. All patients completed a survey assessing their baseline art knowledge, and 4 poststudy validated questionnaires assessing their pain (Pain Rating Scale), hope (Herth Hope Index), anxiety (State-Trait Anxiety Inventory for Adults), and mental wellbeing (Warwick-Edinburgh Mental Wellbeing Scale). A linear model adjusted for baseline scores was run comparing the scores among the 2 study arms. Stepwise multivariate regression analyses were used to identify predictors of improved pain, hope, anxiety, and wellbeing. RESULTS: Both groups were comparable in terms of demographics, passion, and knowledge about art. There was no statistically significant difference in pain scores between the 2 groups. The exposure to art group experienced higher hope (2.4 points higher vs 0.05, P = 0.004), lower anxiety (8 points lower vs -0.9, P < 0.0001), and higher mental well-being scores (5.23 points higher vs -0.05, P < 0.0001) in comparison to the standard of care group. On multivariate analyses, exposure to art was significantly associated with improved hope, anxiety, and mental well-being after adjusting for patient and disease characteristics. CONCLUSIONS: Dedicated exposure to art was associated with improved hope, anxiety, and mental well-being of patients after major oncologic surgery.

Accuracy of American College of Surgeons National Surgical Quality Improvement Program Universal Surgical Risk Calculator in Predicting Complications Following Robot-Assisted Radical Cystectomy at a National Comprehensive Cancer Center.

Introduction: There is paucity of literature about the validation of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) surgical risk calculator for prediction of outcomes after robot-assisted radical cystectomy (RARC). We sought to evaluate the accuracy of the ACS NSQIP surgical risk calculator in the patients who underwent RARC at our institute. Methods: We retrospectively reviewed our prospectively maintained database for patients who underwent RARC between 2005 and 2017. Accuracy of the ACS NSQIP surgical risk calculator was assessed, by comparing the rate of actual complication events after surgery with the receiver operating characteristics curve analysis by calculating the fractional area under the curve (AUC) and the Brier score (BS). We utilized the code number 51595 and 51596 in the ACS NSQIP calculator for the patients undergoing radical cystectomy and reconstructed with the ileal conduit and neobladder, respectively. Results: A total of 462 patients were included in this study: 99 (22%) had diabetes, 302 (66%) had hypertension requiring medication, and 241 (52%) were classified as high American Society of Anesthesiologists (≥3) class. The actual observed rates of any complication and serious complications were 48% and 11%, vs 29% and 25% predicted by the ACS NSQIP, respectively. The actual mean length of hospital stay (10.6 ± 7.8 days) was longer compared with the predicted length (8.5 ± 1.6 days). AUC values were low and the BSs were high for any complication (AUC: 0.50 and BS: 0.29), serious complication (AUC: 0.53 and BS: 0.12), urinary tract infection (AUC: 0.61 and BS: 0.14), renal insufficiency (AUC: 0.64 and BS: 0.08), return to operation room (AUC: 0.58 and BS: 0.07), and early readmission (AUC: 0.55 and BS: 0.11, respectively). Conclusions: The ACS NSQIP calculator demonstrated low accuracy in predicting postoperative outcomes after RARC. These findings highlight the need for development of procedure- and technique-specific RARC calculators.

Use of Robotic Anastomosis Competency Evaluation (RACE) for assessment of surgical competency during urethrovesical anastomosis.

INTRODUCTION: We sought to evaluate the Robotic Anastomosis Competency Evaluation (RACE), a validated tool that objectively quantifies surgical skills specifically for urethrovesical anastomosis (UVA), as a tool to track progress of trainees, and to determine the predictive value of RACE. METHODS: UVAs performed by trainees at our institution were evaluated using RACE over a period of two years. Trainees were supervised by an experienced robotic surgeon. Outcomes included trainee-related variables (RACE score, proportion of UVA performed by trainee, and suturing speed), and clinical outcomes (total UVA duration, postoperative urinary continence, and UVA-related complications). Significance was determined using linear regression analysis. RESULTS: A total of 51 UVAs performed by six trainees were evaluated. Trainee RACE scores (19.8 to 22.3; p=0.01) and trainee proportion of UVA (67% to 80%; p=0.003) improved significantly over time. Trainee suture speed was significantly associated with RACE score (mean speed range 0.54-0.74 sutures/minute; p=0.03). Neither urinary continence at six weeks nor six months was significantly associated with RACE score (p=0.17 and p=0.15, respectively), and only one UVA-related postoperative complication was reported. CONCLUSIONS: Trainee RACE scores improved and proportion of UVA performed by trainees increased over time. RACE can be used as an objective measure of surgical performance during training. Strict mentor supervision allowed safe training without compromising patient outcomes.

Gynecological organ involvement at robot-assisted radical cystectomy in females: Is anterior exenteration necessary?

INTRODUCTION: We aimed to investigate patient and disease variables associated with gynecological organ invasion in females with bladder cancer at the time of robot-assisted radical cystectomy (RARC). METHODS: We conducted a retrospective review of female patients who underwent robot-assisted anterior pelvic exenteration (RAAE) between 2005 and 2016. Patients were divided into two groups: those with gynecological organ involvement at RAAE and those without. Data were reviewed for perioperative and pathological outcomes. Kaplan-Meier method was used to depict survival outcomes. Multivariable stepwise regression analysis was performed to identify predictors of gynecological organ involvement. RESULTS: A total of 118 female patients were identified; 17 (14%) showed evidence of gynecological organ invasion at RAAE. Patients with gynecological organ invasion had more lymphovascular invasion at transurethral resection of bladder tumour (TURBT) (82% vs. 46%; p=0.006), trigonal tumours at TURBT (59% vs. 18%; p=0.001), multifocal disease (65% vs. 33%; p=0.01), pN+ (71% vs. 22%; p<0.001), positive surgical margins (24% vs. 4%; p=0.02), and they less commonly demonstrated pure urothelial carcinoma at TURBT (18% vs. 66%; p<0.001). On multivariate analysis, significant predictors of gynecological organ invasion were pN positive disease (odds ratio [OR] 6.48; 95% confidence interval [CI] 1.64-25.51; p=0.008), trigonal tumour location (OR 5.72; 95% CI 1.39-23.61; p=0.02), and presence of variant histology (OR18.52; 95% CI 3.32-103.4; p=0.001). CONCLUSIONS: Patients with trigonal tumours, variant histology, and nodal involvement are more likely to have gynecological organs invasion at RAAE. This information may help improve counselling of patients and better identify candidates for gynecological organ-sparing cystectomy.

Development of a Patient-Based Model for Estimating Operative Times for Robot-Assisted Radical Prostatectomy.

OBJECTIVES: To develop a methodology for predicting operative times for robot-assisted radical prostatectomy (RARP) using preoperative patient, disease, procedural, and surgeon variables to facilitate operating room (OR) scheduling. METHODS: The model included preoperative metrics: body mass index (BMI), American Society of Anesthesiologists score, clinical stage, National Comprehensive Cancer Network risk, prostate weight, nerve-sparing status, extent and laterality of lymph node dissection, and operating surgeon (six surgeons were included in the study). A binary decision tree was fit using a conditional inference tree method to predict operative times. The variables most associated with operative time were determined using permutation tests. Data were split at the value of the variable that results in the largest difference in mean for surgical time across the split. This process was repeated recursively on the resultant data. RESULTS: A total of 1709 RARPs were included. The variable most strongly associated with operative time was the surgeon (surgeons 2 and 4-102 minutes shorter than surgeons 1, 3, 5, and 6, p < 0.001). Among surgeons 2 and 4, BMI had the strongest association with surgical time (p < 0.001). Among patients operated by surgeons 1, 3, 5, and 6, RARP time was again most strongly associated with the surgeon performing RARP. Surgeons 1, 3, and 6 were on average 76 minutes faster than surgeon 5 (p < 0.001). The regression tree output in the form of box plots showed operative time median and ranges according to patient, disease, procedural, and surgeon metrics. CONCLUSION: We developed a methodology that can predict operative times for RARP based on patient, disease and surgeon variables. This methodology can be utilized for quality control, facilitate OR scheduling, and maximize OR efficiency.

Schistosomiasis and Human Immunodeficiency Virus in Men in Tanzania.

AbstractSchistosomiasis is a parasitic worm infection that affects over 260 million individuals worldwide. Women with schistosome infections have been demonstrated to have a 4-fold increase in the odds of human immunodeficiency virus (HIV) infection compared with women without schistosome infections. A relationship between schistosome and HIV infections has not been clearly defined in men. Among 674 men aged 18-50 years living in rural Tanzania, we identified 429 (63.6%) who had a schistosome infection as defined by serum positivity for schistosome circulating anodic antigen, visualization of parasite eggs in urine or stool, or both. HIV infection was identified in 38 (5.6%). The odds of HIV infection was 1.3 [95% confidence interval = 0.6-2.5] (P = 0.53) among men with any schistosome infection (Schistosoma haematobium or Schistosoma mansoni), and it was 1.4 [0.6-3.3] (P = 0.43) among men with S. haematobium infection. Men with S. haematobium infection were significantly more likely to report the symptom of hemospermia than men without S. haematobium infection. We conclude that schistosome infections appear to have little to no association with HIV infection in men.

Food insecurity, but not HIV-infection status, is associated with adverse changes in body composition during lactation in Ugandan women of mixed HIV status.

BACKGROUND: Body composition is an important indicator of nutritional status and health. How body composition changes during 12 mo of breastfeeding in HIV-infected women receiving antiretroviral therapy (ART) is unknown. OBJECTIVE: We assessed whether HIV or food insecurity was associated with adverse postpartum body-composition changes in Ugandan women. DESIGN: A cohort of 246 women [36.5% of whom were HIV positive (HIV+) and were receiving ART] were followed to 12 mo postpartum. Repeated measures included weight, fat mass, fat-free mass, midupper arm circumference, triceps skinfold thickness [which allowed for the derivation of arm muscle area (AMA) and arm fat area (AFA)], breastfeeding, and individual food insecurity. Longitudinal regression models were constructed to assess associations between HIV and food insecurity and changes in body composition over time. RESULTS: At baseline, HIV+ women compared with HIV-negative women had a higher mean ± SD food-insecurity score (11.3 ± 5.5 compared with 8.6 ± 5.5, respectively; P < 0.001) and lower AMA (40.6 ± 5.7 compared with 42.9 ± 6.9 cm3, respectively; P = 0.03). Participants were thin at 1 wk postpartum [body mass index (BMI; in kg/m2): 22.9 ± 2.9]. From 1 wk to 12 mo, the weight change was -1.4 ± 4.4 kg. In longitudinal models of body-composition outcomes, HIV was not associated with body composition (all P > 0.05), whereas food insecurity was inversely associated with body weight and BMI at 6, 9, and 12 mo and with AFA at 6 and 12 mo (all P < 0.05). At 6 mo, every 1-unit increase in the food-insecurity score was associated with a 0.13-kg lower body weight (P < 0.001) and a 0.26-cm3 lower AFA (P < 0.01). CONCLUSIONS: Body-composition changes are minimal during lactation. HIV is not associated with body composition; however, food insecurity is associated with changes in body composition during lactation. This trial was registered at clinicaltrials.gov as NCT02922829 and NCT02925429.
