Surgical confidence when operating among residents in surgery - a cross-sectional study (SCAR study).

BACKGROUND: Self-confidence, is one of the critical variables influencing surgical resident's abilities, and lack of confidence maybe a reason for not entering medical practice immediately. Measuring the level of confidence of senior surgical residents (SSRs) is a crucial step in assessing preparedness to practice. In this study, we aim to measure their confidence level and the factors that might contribute to it. METHODS: Cross-sectional survey conducted at King Abdulaziz University Hospital on SSRs in Saudi Arabia (SA). We approached 142 SSRs, 127 responded. Statistical analysis was performed using RStudio v 3.6.2. Descriptive statistics were performed using counts and percentages for categorical variables and using mean ± standard deviation for continuous variables. Multivariate linear regression (t-statistics) was used to assess the factors associated with confidence in performing essential procedures, while the association between demographics and residency-related factor with the number of completed cases was tested using Chi-square. The level of significance was determined as 0.05. RESULTS: Response rate was 89.4%. Among surveyed residents, 66% had completed < 750 cases as a primary surgeon. More than 90% of SSRs were confident in performing appendectomy, open inguinal hernia repair, laparoscopic cholecystectomy, and trauma laparotomy, while 88% were confident in being on-call in level-I trauma center. No difference was noted in confidence level in relation to the number of performed cases. Residents from the Ministry of Health accounted for 56.3% of the study population and showed a higher confidence level compared to others. 94% of SSRs plan to pursue fellowship training program. CONCLUSION: The study showed that the confidence of SSRs in performing common general surgery procedures was as expected. However, it's important to recognize that confidence doesn't necessarily reflect competence. Considering the majority of SSRs planned to pursue fellowship training programs, it may be time to consider changing the structure of surgical training in SA to a modular format to allow earlier and more intensive exposure.

Body Microbiota and Its Relationship With Benign and Malignant Breast Tumors: A Systematic Review.

Breast cancer is the most frequent type of cancer as well as one of the main causes of cancer-related mortality in women. Human microbial dysbiosis, which has been related to a range of malignancies, is one of the variables that may impact the chance of developing breast disorders. In this review, we aimed to investigate the relationship between breast cancer and benign breast tumors with dysbiosis of the microbiome at different body sites. We performed a systematic review of MEDLINE, Scopus, Ovid, and Cochrane Library to identify original articles published until July 2020 that reported studies of breast disease and microbiota. Twenty-four original articles were included in the study, which looked at the features and changes in breast, gut, urine, lymph node, and sputum microbial diversity in patients with benign and malignant breast tumors. In breast cancer, the breast tissue microbiome demonstrated changes in terms of bacterial load and diversity; in benign breast tumors, the microbiome was more similar to a malignant tumor than to normal breast tissue. Triple-negative (TNBC) and triple-positive (TPBC) types of breast cancer have a distinct microbial pattern. Moreover, in breast cancer, gut microbiota displayed changes in the compositional abundance of some bacterial families and microbial metabolites synthesis. Our review concludes that breast carcinogenesis seems to be associated with microbial dysbiosis. This information can be further explored in larger-scale studies to guide new prophylactic, diagnostic, and therapeutic measures for breast cancer.

Factors Affecting Ulcerative Colitis Flare-Ups: Associations With Smoking Habits and Other Patient Characteristics.

Background and study aims Currently, there are no studies conducted in the Kingdom of Saudi Arabia (KSA) that have assessed the relationship between ulcerative colitis (UC) flare-ups and smoking. The present study aims to assess the risk of UC flare-ups and evaluate the relationship between UC flare-ups and smoking in adult patients following up at King Abdulaziz University Hospital in Jeddah, KSA. Patients and methods This was a retrospective study involving patients with confirmed UC between January 2015 and December 2020. Various information was examined, including demographic, clinical, endoscopic, radiologic, and laboratory data. Descriptive statistics were used for summarizing findings and a logistic regression analysis was applied to test for possible associations. Results Eighty-nine patients with UC were included in the study. Almost half (48.3%) had recurrent UC flare-ups during follow-up. A non-significant relationship was found between recurrent UC flares and all types of smoking habits (cigarette smoking, P = 0.15; shisha smoking, P = 0.88; and vape smoking, P = 0.09). Participants who were underweight (P = 0.041), had family history of UC (P = 0.013), depression (P = 0.033), fecal incontinence (P = 0.003), iron deficiency anemia (P = 0.009), or a malignancy (P = 0.039) had a significantly higher probability of experiencing recurrent flares. Binary logistic regressions revealed that family history of UC (OR = 5.3, P = 0.007) and fecal incontinence (OR = 4.7, P = 0.006) were associated significantly with recurrent flares. Conclusion There was no clear association between smoking and recurrent UC flares identified in this cohort. Of the variables considered, UC patients with fecal incontinence or family history of UC were at the highest risk of developing recurrent flares.

Locally Advanced Breast Cancer: Treatment Patterns and Predictors of Survival in a Saudi Tertiary Center.

Background  Breast cancer (BC) is the most common cancer in the Kingdom of Saudi Arabia (KSA) and the second leading cause of cancer-related mortality. About 40% of BC in KSA is locally advanced BC (LABC), which has been associated with poorer survival compared with early diagnosed BC. Objective To review the presentation and outcomes of LABC, including the characteristics of the disease, different treatment modalities, overall survival (OS), disease-free survival (DFS), and local recurrence in relation to different radiotherapy (RT) techniques. Methods  We retrospectively reviewed the medical records of 153 female patients with pathologically proven LABC diagnosed at King Abdulaziz University Hospital, Jeddah, KSA, between 2009 and 2017. We obtained data on patient demographics, stage of cancer at diagnosis, tumor characteristics (subtype and receptor status), type of surgery, systemic treatments received (hormonal, targeted therapy, and chemotherapy), RT variables, and recurrence and death dates. Data were analyzed to assess OS and DFS by using Kaplan-Meier analyses and the log-rank test. Univariate and multivariate Cox proportional hazard regression analyses were used to explore and identify factors associated with survival. Results  The median survival time in the study population was 9.16 years. Older age (65+ years) was associated with worse OS and DFS than was younger age (<65 years) (hazard ratio (HR) 3.20, 95% CI 1.48-6.90, P = 0.003 and HR 2.21, 95% CI 1.12-4.36, P = 0.022, respectively). Regarding the type of surgery, having a mastectomy was associated with worse OS and DFS than was having a lumpectomy (HR 2.44, 95% CI 0.97-6.12, P = 0.05 and HR 2.41, 95% CI 1.13-5.14, P = 0.023, respectively). Positive estrogen and progesterone receptor status was associated with better OS and DFS than was a negative estrogen or progesterone receptor status (HR 0.13, 95% CI 0.05-0.30, P < 0.001 and HR 0.21, 95% CI 0.11-0.41, P < 0.001, respectively). Patients who received RT had a lower risk of recurrence than did those who did not receive RT (P = 0.011). Moreover, three-dimensional conformal RT was associated with lower local recurrence than intensity-modulated RT or volumetric-modulated arc therapy (P = 0.003). Conclusion  Multiple factors can affect the OS and DFS in LABC. Younger patients, having hormone-positive disease, and undergoing lumpectomy were associated with better outcomes. Adjuvant RT may improve local control and the use of three-dimensional conformal RT was superior for local control. Prospective studies with larger sample sizes are needed to further highlight these findings and to assess the role of chemotherapy and targeted therapy in patients with LABC.

Short-term outcomes of stents in obstructive rectal cancer: A systematic review and meta-analysis.

BACKGROUND: With acute obstruction due to rectal or recto-sigmoid cancer, the safety and success of deploying self-expandable metal stents has been controversial. The aim of this systematic review was to synthesize the existing evidence on the outcomes and complication rates of stent placement in these patients. METHODS: We performed a literature search of PubMed by using appropriate keywords, and manual reference screening of included articles was done. The article screening, data extraction, and quality assessment was done by four independent reviewers. A meta analyses was performed for the main outcome measures: technical and clinical success and complication rates. RESULTS: We identified 962 articles in the search. After applying inclusion and exclusion criteria, we included 32 articles in the meta-analysis. The pooled technical success rate across 26 studies that reported it was 97% [95% confidence interval (CI): 95%-99%] without evidence of significant heterogeneity (I2 = 0.0%, P = 0.84), and the clinical success rate across 26 studies that reported it was 69% (95% CI: 58%-79%) with evidence of significant heterogeneity (I2 = 81.7%, P < 0.001). The pooled overall complication rate across the 32 studies was 28% (95% CI: 20%-37%) with evidence of significant heterogeneity (I2 = 79.3%, P < 0.001). CONCLUSION: The use of rectal stents in obstructing rectal or recto-sigmoid tumors seems to be technically feasible. A high rate of technical success, however, does not always translate into clinical success. A considerable complication rate is associated with this approach. Randomized controlled trials are needed to compare the outcomes of rectal stent placement with those of surgery.
