Assessing the knowledge, attitude, and practice of frontline physicians in Egyptian university hospitals regarding pharyngitis and acute rheumatic fever: a cross-sectional study that calls for action.

BACKGROUND: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major public health issues. Although the primary and secondary prevention of RHD through appropriate management of bacterial pharyngitis and ARF are well-described in the literature, few studies address the knowledge, attitude, and practice (KAP) of developing countries. We aimed to evaluate the KAP of the frontline physicians in Egyptian university hospitals regarding pharyngitis and ARF. METHODS: We employed a cross-sectional design between September 1st, 2022, and January 31st, 2023 using a self-administered questionnaire in 21 Egyptian universities. The questionnaire was developed based on previous studies and recent guidelines and included four domains: sociodemographic data, knowledge, attitude, and practice regarding pharyngitis and ARF. We utilized both online (Google Forms) and paper surveys. Frontline physicians, including interns, residents, and assistant lecturers, were conveniently invited to participate. Furthermore, with the help of participating phycisians in recruiting their colleagues, we utilized the snowball method. Data were analyzed using IBM SPSS version 27 software. RESULTS: The final analysis included 629 participants, of whom 372 (59.1%) were males and 257 (40.9%) had direct contact with ARF patients. Most participants (61.5%) had a fair knowledge level while 69.5% had a fair level of practice regarding ARF and pharyngitis. Higher satisfactory knowledge levels were noted regarding pharyngitis (17.1% vs. 11.3%; p-value: 0.036) and ARF (26.8% vs. 18%; p-value: 0.008) among physicians dealing directly with ARF cases compared to physicians in departments not dealing directly with ARF cases. Physicians in Cairo region universities had significantly higher levels of satisfactory knowledge about ARF compared to Delta and Upper Egypt region universities (p = 0.014). Delta region universities showed significantly lower levels of practice compared to Cairo and Upper Egypt region universities (p = 0.027). The most frequently recognized barriers against health promotion were low socioeconomic status (90.3%) and lack of adequate public education (85.8%). CONCLUSIONS: Despite the fair knowledge and practice levels towards bacterial pharyngitis and ARF among participants, many gaps were still identified that might contribute to RHD prevalence. Educational interventions should be implemented by updating the local guidelines in Egypt for diagnosis and management based on the most recent guidelines.

Robotic Mitral Valve Surgery.

Growing interest in minimalizing surgical trauma during heart procedures stimulated the development of robotic mitral valve surgery in the late 1990s. Initially, the new technology was slowly adopted in clinical practice. However, following encouraging results by teams that adopted robotic heart surgery early on, a growing interest in implementation of robotic mitral valve surgery has emerged. Of importance are the technical developments and possibilities that accompany robotic surgery. Robotic arms feature unique characteristics, allowing unparalleled range of motion and allowing complex mitral valve repair techniques to be performed without limitations related to limited surgical incisions. High-quality three-dimensional vision effectively compensates for the lack of tactile feedback. Several technical solutions have been developed to facilitate mitral valve repair in minimal invasive setting, including chordal guiding systems, now available with various annuloplasty rings. On the other hand, precise vision and movements allows accurate determination of the length of implanted neochordae, facilitating precise determination of the length of implanted neochords even without the use of chordal-guiding systems. With robotic mitral valve surgery, leaflet resection techniques can be performed without limitations, ensuring that no compromises of the surgical strategy are made. Nevertheless, careful preoperative planning with appropriate work-up and imaging is of utmost importance to prevent complications. Moreover, the drawbacks of the initial learning curve and higher procedural costs are counterbalanced by less surgical trauma, lower utilization of blood products, and faster patient recovery. Robotic mitral valve surgery is still a young field and evolving technology that is bound to become an important tool in the toolbox of surgical mitral valve approaches.

Robot-assisted thoracic surgery for stages IIB-IVA non-small cell lung cancer: retrospective study of feasibility and outcome.

Robot-assisted thoracic surgery (RATS) for higher stages non-small cell lung carcinoma (NSCLC) remains controversial. This study reports the feasibility of RATS in patients with stages IIB-IVA NSCLC. A single-institute, retrospective study was conducted with patients undergoing RATS for stages IIB-IVA NSCLC, from January 2015 until January 2020. Unforeseen N2 disease was excluded. Data were collected from the Dutch Lung Cancer Audit database. Conversion rate, radical (R0) resection rate, local recurrence rate and complications were analyzed, as were risk factors for conversion. RATS was performed in 95 patients with NSCLC clinical or pathological stages IIB (N = 51), IIIA (N = 39), IIIB (N = 2) and IVA (N = 3). 10.5% had received neoadjuvant chemoradiotherapy. Pathological staging was T3 in 33.7% and T4 in 34.7%. RATS was completed in 77.9% with a radical resection rate of 94.8%. Lobectomy was performed in 67.4% of the total resections. Conversion was for strategic (18.9%) and emergency (3.2%) reasons. Pneumonectomy (p = 0.001), squamous cell carcinoma (p < 0.001), additional resection of adjacent structures (p = 0.025) and neoadjuvant chemoradiation (p = 0.017) were independent risk factors for conversion. Major post-operative complications occurred in ten patients (10.5%) including an in-hospital mortality of 2.1% (n = 2). Median recurrence-free survival was estimated at 39.4 months (CI 16.4-62.5). Two- and 5-year recurrence-free survival rates were 53.8% and 36.7%, respectively. This study concludes that RATS is safe and feasible in higher staged NSCLC tumors after exclusion of unforeseen N2 disease. It brings new perspective on the potential of RATS in higher stages, dealing with larger and more invasive tumors.

Training in robotic thoracic surgery-the European way.

The increasing demand for robot-assisted thoracic surgery (RATS) in Europe requires a structured and standardized training module. Until now, Intuitive Surgical Inc. (Sunnyvale, CA, USA) has delivered the only available robotic surgery platform. Although the training program that is organized by Intuitive is divided in an initial and an advanced course, the success of the training depends on many external factors. Until now the training focused on experienced thoracic surgeons. The aim of this article is to offer a stepwise training module, which can be adopted by experienced open (thoracotomy) surgeons or video-assisted thoracic (VATS) surgeons but is primarily meant for thoracic surgery fellows and residents, as it is our sincere opinion that we should focus on training for this type of surgery as early in their careers as possible. In order to maintain surgical technique and minimize the chance of complications, on-going training and certification of the surgeons and the team is deemed necessary.

Outcomes from the Delphi process of the Thoracic Robotic Curriculum Development Committee.

OBJECTIVES: As the adoption of robotic procedures becomes more widespread, additional risk related to the learning curve can be expected. This article reports the results of a Delphi process to define procedures to optimize robotic training of thoracic surgeons and to promote safe performance of established robotic interventions as, for example, lung cancer and thymoma surgery. METHODS: In June 2016, a working panel was spontaneously created by members of the European Society of Thoracic Surgeons (ESTS) and European Association for Cardio-Thoracic Surgery (EACTS) with a specialist interest in robotic thoracic surgery and/or surgical training. An e-consensus-finding exercise using the Delphi methodology was applied requiring 80% agreement to reach consensus on each question. Repeated iterations of anonymous voting continued over 3 rounds. RESULTS: Agreement was reached on many points: a standardized robotic training curriculum for robotic thoracic surgery should be divided into clearly defined sections as a staged learning pathway; the basic robotic curriculum should include a baseline evaluation, an e-learning module, a simulation-based training (including virtual reality simulation, Dry lab and Wet lab) and a robotic theatre (bedside) observation. Advanced robotic training should include e-learning on index procedures (right upper lobe) with video demonstration, access to video library of robotic procedures, simulation training, modular console training to index procedure, transition to full-procedure training with a proctor and final evaluation of the submitted video to certified independent examiners. CONCLUSIONS: Agreement was reached on a large number of questions to optimize and standardize training and education of thoracic surgeons in robotic activity. The production of the content of the learning material is ongoing.

The Carpentier-Edwards Classic and Physio mitral annuloplasty rings: a randomized trial.

OBJECTIVE: To evaluate clinical and echocardiographic outcomes for the semi-flexible Carpentier-Edwards Physio and the rigid Classic mitral annuloplasty ring. METHODS: Ninety-six patients were randomized for either a Classic (n = 53) or a Physio (n = 43) ring from October 1995 through July 1997. Mean follow-up was 5.1 years (range .1-6.6). We included standard patient characteristics at baseline and during follow-up. Analyses were adjusted for age and gender, and for factors that differed across groups at baseline. In 2002, echocardiography was performed in 74% of the survivors. RESULTS: We found a 16% difference in mortality: 14% in the Physio group (n = 6) and 30% in the Classic group (n = 16) (adjusted P = .41). Life table analysis shows that the absolute risk of death after 30 months is lower in the Physio group. Intra-operative repair failure occurred in 3 patients (6%) of the Classic group, and in 4 (9%) of the Physio group, resulting in mitral valve replacement. Late failure occurred in 1 patient (2%) in the Classic group, and in 4 (9%) in the Physio group. At follow-up, left ventricular function did not differ across groups (ejection fraction 45% and 48% (adjusted P = .65)). The combined NYHA class III-IV had improved for the Classic group in 42% and for the Physio group in 34%. CONCLUSION: Although the 16% difference in mortality did not reach statistical significance, it is considered clinically important. No differences in morbidity, valve function, and left ventricular function were found. Further research to explain the difference in mortality is required.

Congenital circumflex artery-coronary sinus fistula in an adult female associated with severe mitral regurgitation and myelodysplasy--case report and review of the literature.

BACKGROUND: Coronary artery fistulas are uncommon anomalies. They occur in 0.1-0.2% of patients undergoing coronary arteriography. The origin of the fistulas is the right coronary artery followed by the left anterior descending and lastly by the circumflex artery (17%). Termination into the right heart side occurs in 90% of cases. Termination into the coronary sinus is rare in 3% of cases. Circumflex artery-coronary sinus fistulas are even rarer. DESIGN: A single case report and literature review between 1993 and 2007. RESULTS: We describe a 76-year-old female, who was analyzed for dyspnea on exertion (DOE) and chronic fatigue, with known myelodysplastic syndrome and an aneurysmal circumflex coronary artery-coronary sinus fistulous connection associated with severe mitral regurgitation. Mitral valve replacement using a bioprosthesis was performed as well as ligation of the fistula. The postoperative course was complicated with cardiac tamponade, which was successfully drained. CONCLUSION: Our patient presented with chronic fatigue and DOE and was found to have a coronary artery fistula and severe mitral regurgitation associated with known myelodysplasia. Conventional coronary angiography failed to demonstrate the entire fistula characteristics (origin, pathway, and outflow). Multidetector computed tomography was complementary to demonstrate the complex anatomy of the fistula. The fistula was surgically ligated in combination with mitral valve replacement. She remains well.

Long-term follow-up of mitral valve repair: a single-center experience.

BACKGROUND: Our aim was to conduct a long-term follow-up of patients after mitral valve repair for incompetence. We identified determinants for mortality and compared mortality with standardized mortality rates of the Dutch population. MATERIAL/METHODS: We included in this single-center retrospective study 119 patients operated from March 1976 to February 1981. Patients with previous mitral valve surgery, isolated mitral stenosis, and congenital heart disease were excluded. Routine echocardiography was performed every 6 to 12 months. The cumulative probability of survival was calculated (Kaplan-Meier). The variables that statistically significantly associated with mortality were selected for multivariate analysis. Maximum follow-up was 27 years and complete in 98%. Mean age was 49.4 years, and 55% were preoperatively in New York Heart Association (NYHA) class III. Concomitant cardiac procedures were performed in 49%. RESULTS: The 30-day postoperative mortality was 6.7% and the 20-year overall mortality was 63%. The standardized mortality rate was 30%, which was based on survival rates of the general Dutch population. In 27 cases (22.7%), re-operation was performed. Independent predictors for mortality were, after univariate and multivariate analysis, concomitant coronary artery bypass grafting (p=0.002), renal impairment (p=0.027), age above 60 years (p=0.05), and ejection fraction
