Longitudinal Evaluation of Congenital Cardiovascular Surgical Performance and Skills Retention Using Silicone-Molded Heart Models.

Objective: Hands-on surgical training (HOST) for congenital heart surgery (CHS), utilizing silicone-molded models created from 3D-printing of patients' imaging data, was shown to improve surgical skills. However, the impact of repetition and frequency of repetition in retaining skills has not been previously investigated. We aimed to longitudinally evaluate the outcome for HOST on two example procedures of different technical difficulties with repeated attempts over a 15-week period. Methods: Five CHS trainees were prospectively recruited. Repair of coarctation of the aorta (CoA) and arterial switch operation (ASO) were selected as example procedures of relatively low and high technical difficulty. Procedural time and technical performance (using procedure-specific assessment tools by the participant, a peer-reviewer, and the proctor) were measured. Results: Coarctation repair performance scores improved after the first repetition but remained unchanged at the follow-up session. Likewise, CoA procedural time showed an early reduction but then remained stable (mean [standard deviation]: 29[14] vs 25[15] vs 23[9] min at 0, 1, and 4 weeks). Conversely, ASO performance scores improved during the first repetitions, but decreased after a longer time delay (>9 weeks). Arterial switch operation procedural time showed modest improvements across simulations but significantly reduced from the first to the last attempt: 119[20] versus 106[28] min at 0 and 15 weeks, P = .049. Conclusions: Complex procedures require multiple HOST repetitions, without excessive time delay to maintain long-term skills improvement. Conversely, a single session may be planned for simple procedures to achieve satisfactory medium-term results. Importantly, a consistent reduction in procedural times was recorded, supporting increased surgical efficiency.

Bidirectional glenn surgery without palliative pulmonary artery banding in univentricular heart with unrestricted pulmonary flow. Retrospective multicenter experience.

BACKGROUND: Although pulmonary artery banding (PAB) has been generally acknowledged as an initial palliative treatment for patients having single ventricle (SV) physiology and unrestrictive pulmonary blood flow (UPBF), it may result in unfavorable outcomes. Performing bidirectional Glenn (BDG) surgery without initial PAB in some selected cases may avoid the complications associated with PAB and reduce the number of operative procedures for these patients. This research aimed to assess the outcome of BDG surgery performed directly without doing initial PAB in patients with SV-UPBF. METHODS: This Multicenter retrospective cohort includes all patients with SV-UPBF who had BDG surgery. Patients were separated into two groups. Patients in Group 1 included patients who survived till they received BDG (20 Patients) after initial PAB (28 patients), whereas patients in Group 2 got direct BDG surgery without first performing PAB (16 patients). Cardiac catheterization was done for all patients before BDG surgery. Patients with indexed pulmonary vascular resistance (PVRi) ≥ 5 WU.m2 at baseline or > 3 WU.m2 after vasoreactivity testing were excluded. RESULTS: Compared with patients who had direct BDG surgery, PAB patients had a higher cumulative mortality rate (32% vs. 0%, P = 0.016), with eight deaths after PAB and one mortality after BDG. There were no statistically significant differences between the patient groups who underwent BDG surgery regarding pulmonary vascular resistance, pulmonary artery pressure, postoperative usage of sildenafil or nitric oxide, intensive care unit stay, or hospital stay after BDG surgery. However, the cumulative durations in the intensive care unit (ICU) and hospital were more prolonged in patients with BDG after PAB (P = 0.003, P = 0.001respectively). CONCLUSION: Direct BDG surgery without the first PAB is related to improved survival and shorter hospital stays in some selected SV-UPBF patients.

Insight of the Biopharmaceutical Implication of Sleeve Gastrectomy on Levothyroxine Absorption in Hypothyroidism Patients.

PURPOSE: The growing rate of obesity led to an increased number of bariatric surgeries (BS) as a treatment option for obesity. The gastrointestinal tract (GIT) changes following BS can impact many drugs' absorption. Levothyroxine (LT4) is a synthetic thyroxine (T4) replacement used commonly as tablets to manage hypothyroidism disorder, which is more prevalent among patients with obesity. This study aims to examine the LT4 oral tablet form therapy after sleeve gastrectomy. MATERIALS AND METHODS: A retrospective cohort study was conducted in multi-center. The LT4 doses and TSH and T4 levels were compared before and after BS. The post-surgery readings were categorized into three periods: (one to three months), (four to six months), and (> six ) months after surgery. ANOVA test was used for analysis. RESULTS: A total of 14374 patients who underwent BS from (1/2019 to 3/2022) were screened for eligibility, and n = 101 participants matched the inclusion criteria. The TSH and T4 were not statistically significant differences before and after surgery (P-values of 0.4864 and 0.5970, respectively). However, the doses significantly differed before and after surgery in all the follow-up time point periods (P < 0.002). CONCLUSION: The LT4 required doses significantly reduced after sleeve gastrectomy, which can be related to the improved endogenous thyroid production in patients with obesity. However, the abnormality of the GIT induced by the sleeve gastrectomy may affect the exogenous LT4 absorption. Using liquid forms of LT4 while monitoring the thyroid function parameters can optimize the treatment after the procedure.

Uncontrolled Asthma Among Children and Its Association With Parents' Asthma Knowledge and Other Socioeconomic and Environmental Factors.

Objective To estimate the frequency of uncontrolled asthma among asthmatic children from Jeddah and to analyze its association with parental asthma knowledge and other socioeconomic and environmental factors. Method A cross-sectional study was conducted at the Pediatrics Departments of King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia, from July to December 2018. It involved the caregivers of 150 children with asthma, who were following at KAUH. A structured questionnaire was administered by a phone interview to collect the following: socioeconomic and environmental factors of asthma, answers to the Arabic version of the Asthma Control TestTM (ACT), and answers to the Arabic version of the caregiver Asthma Knowledge questionnaire (AKq). Result The frequency of uncontrolled asthma was 32.7% (95%CI: 25.2 - 40.8). Parents had myths about asthma such as "children with asthma should use asthma control medications (inhaled corticosteroids) only when they have symptoms" and "it's not good for children to use the inhaler for too long". Besides, we observed mixed results regarding parents' knowledge about the disease, with correct answers ranging from 56.0% to 88.7% depending on the item. Exposure to bakhoor (aromatic woodchips) at home (OR = 0.41, p=0.044), two or more ICU admissions during the past 12 months (OR = 3.30, p=0.030), and using a rescue inhaler even if there's no cough or wheeze when the child gets the flu (OR = 0.22, p=0.001) were the three independent factors of uncontrolled asthma among children. Conclusion Uncontrolled asthma concerns one-third of the asthmatic children following at our centre, representing a less concerning figure compared to the national data. The contribution of parents' knowledge to asthma control did not show significant results, although uncontrolled asthma may represent an opportunity to increase parents' knowledge and awareness. We emphasize the significance of exposure to bakhoor, the use of oral steroids, and the number of ICU admission as strong indicators for uncontrolled asthma in children. An adaptive national strategy should be designed to enable effective and personalized interventions, resources, and objectives for maximized benefits.

A robotic-assisted hybrid coronary revascularization program: Establishment and early experience in the Middle East.

BACKGROUND: Hybrid coronary revascularization (HCR) is a technique that merges coronary artery bypass grafting surgery and percutaneous coronary intervention (PCI) approaches for the treatment of multivessel coronary artery disease. The surgical component of the procedure is minimally invasive and can be done using robotic technology that avoids the need for sternotomy. Our objective is to study all patients who underwent robotic-assisted HCR (RHCR) to evaluate the feasibility and safety of the procedure during the establishment phase. METHODS: This study is a retrospective chart review conducted at King Faisal Specialist Hospital and Research Centre in Jeddah (KFSRC-J). The study focuses on patients who underwent RHCR between July 2018 to December 2020. The study was approved by the institutional review board #2020-103. RESULTS: Robotic-assisted HCR was performed on 78 patients (mean age, 56 years (range, 43-72 years); 89.75% males) during the study phase. Left internal mammary artery grafting was used in all patients. There was no hospital mortality, and the mean hospital and intensive care unit (ICU) stay were 5.8 and 1.4 days, respectively. We found that 93.6% of the patients had no blood transfusion. There were no major adverse cardiac events (MACE) and perioperative MI recorded. There was a 3.8% rate of postoperative complications. The percentage of surgeries converted to conventional and re-exploration for bleeding were 1.2% and 2.6%, respectively. The average operation time was 164 min. CONCLUSION: This study emphasizes on the safety and effectiveness of RHCR in treating patients with multivessel coronary artery disease. Moreover, robotic-assisted hybrid coronary revascularization offers an alternative, functionally complete revascularization option to a selected group of patients with minimal surgical trauma, short hospital and ICU length of stay, quick recovery, and little to no blood transfusion requirement.

Fast-Food Consumption, Dietary Quality, and Dietary Intake of Adolescents in Saudi Arabia.

High fast-food consumption is a common public-health concern among adolescents, due to its link to a number of non-communicable diseases. Frequent consumption of fast food may also affect diets of individuals; however, research addressing this issue is lacking in Saudi Arabia. We aimed to investigate the association between fast-food consumption, dietary quality, and dietary intake of adolescents in Saudi Arabia. This is a cross-sectional study of 617 healthy adolescents aged 11-18 years, who were recruited randomly from 16 middle- and high-schools located in Jeddah and Madinah, Saudi Arabia. Sociodemographic data were collected from parents. Dietary data, including the frequency of fast-food consumption, dietary quality (assessed using the short-form food frequency questionnaire), and dietary intake (assessed using multiple 24 h diet recalls from a subsample), were collected from the adolescents. Approximately one-third of adolescents (28.5%) reported frequent fast-food consumption (>two times a week). Results showed that a higher proportion of male adolescents frequently consumed fast-food, compared with female adolescents (32.8% vs. 24.8%, p = 0.039). Adolescents with the highest monthly family-income (≥SAR 21,000 ) reported a significantly higher frequency of fast-food consumption compared with families with a lower monthly income (p = 0.009). Frequency of fast-food consumption predicted lower dietary-quality in adolescents (Beta (B) = -0.27 [95% confidence interval (CI): -0.35 to -0.18]) and higher carbohydrate and free-sugar intake (B = 6.93 [95% CI: 0.78 to 13.1], and B = 3.93 [95% CI: 1.48 to 6.38], respectively). In conclusion, nutrition-intervention programs aiming to limit fast-food consumption and enhance the dietary quality of adolescents in Saudi Arabia, are warranted.

Prevalence, patterns, and attitude regarding dietary supplement use in Saudi Arabia: Data from 2019.

Dietary supplements are products containing dietary elements including vitamins, minerals, amino acids, herbs, or botanicals. They can aid consumers with low dietary intake and quality, as well as those with high demands, by boosting nutritious value. A cross-sectional study was conducted among adults living in Saudi Arabia aged between 18-60 years old using online self-administered questionnaire. Information regarding sociodemographic characteristics, use and type of dietary supplements, and attitude toward and patterns of dietary supplement use was collected. The chi-square test, Pearson correlations, and the independent t-test were used. In total, 531 participants (115 men and 416 women) were included. Approximately half of the participants (51.8%, n = 275) used dietary supplements. Participants who were using dietary supplements were significantly younger (29.16 ± 9.32 years), more highly educated (85.5%, n = 235), and worked in the health sector (63.7%, n = 100). Herbal supplement use was associated with older age and female sex. Single mineral supplements were used more frequently by married, female, pregnant, or breastfeeding participants and those not working in the health sector. Fatty supplements were used more frequently by participants with a higher level of education. Regarding the attitude toward dietary supplement use, women, single participants, and health care workers showed a significant positive attitude. In-depth investigation into the amount of and reasons for dietary supplement use in the health sector is required. Additionally, educating pregnant and breastfeeding women on the importance of dietary supplements is necessary.

Mitral valve replacement in infants and younger children.

Data on mitral valve replacement (MVR) in young children is still limited. Our objective was to evaluate MVR in children below 5 years and identify factors affecting the outcomes. This retrospective study included 29 patients who had MVR from 2002 to 2020. We grouped the patients into two groups according to their age: age ≤ 24 months (n = 18) and > 24 months (n = 11). Primary cardiac diagnoses were Shone complex (n = 7; 24%), isolated congenital mitral valve abnormality (n = 11; 38%), and complete atrioventricular septal defect (n = 3; 10%). The median age was 19 month (25th-75th percentile: 11-32) and 59% were females (n = 17). The hemodynamic lesions were mitral regurgitation in 66%, mitral stenosis in 10%, and combined mitral stenosis and regurgitation in 24% of the patients. St. Jude mitral valve was the most common valve implanted (n = 19, 66%), followed by CarboMedics in 21% of the patients (n = 6). The mitral valve was implanted in the supra-annular position in 6 cases (21%). Preoperative and operative data were comparable between both groups. There was no association between valve size and position with postoperative heart block (P > 0.99, for both). The median follow-up duration was 19.4 months (8.6-102.5). Nine patients had mitral valve reoperation, six had MVR, and three had clot removal from the mitral valve. There was no effect for age group on reoperation (SHR 0.89 (95% CI 0.27-2.87), P = 0.84). Valve size significantly affected reoperation (SHR 0.39 (95% CI 0.18-0.87), P = 0.02). The supra-annular position was associated with an increased risk of reoperation (SHR 3.1 (95% CI 1.003-9.4), P = 0.049). There was no difference in survival according to the age (Log-rank P = 0.57) or valve size (Log-rank P = 0.66). Mitral valve replacement in children is associated with low morbidity and mortality. The risk of reoperation could be affected by the valve size and position rather than the age.

A Field-Based Study of the Magnitude of Risk Factors and Health Habits in Young Volunteers in the Community.

Objective A field study is more informative in terms of epidemiological data than a hospital-based study. Undiagnosed risk factors may be discovered in an asymptomatic group. This study aimed to estimate if the community was well informed about the risk factors for coronary artery disease and if that affected the prevalence and the anthropometric among those who participated in the study. Materials and methods A cross-sectional study was conducted, using a consecutive sampling technique. Individuals were interviewed in terms of the risk factors and clinical signs and symptoms. The anthropometric measurements were done on-site to identify asymptomatic risk factors. The survey was utilized to increase the awareness among the participants. Results In total, 193 individuals participated in this study. The mean age of the sample was 36.3 ± 12.4 years, with 53% male. Smoking was the most frequent risk factor (31.6%), followed by dyslipidemia (22.5%), hypertension (16.6%), and diabetes mellitus (14.5%). Almost half of the sample participated in sports for one to two hours per week (40%). Almost all consumed fast food at least once a week, and 16.6% consumed fast food more than four times a week. The average systolic blood pressure was 129.41 ± 22.5 mmHg and the average body mass index (BMI) 27.6 ± 7.2 kg/m2. Conclusion Dyslipidemia was the most prevalent risk factor. Hypertension and diabetes mellitus are on top of the risk factor pyramid in commonality. An early diagnosis is important to decrease the incidence of cardiovascular disease. The consumption of fast food and obesity are relatively high and require educational interventions and more available healthy food. Screening through social media and primary health care centers may avert a negative outcome.

The outcomes of bidirectional Glenn before and after 4 months of age: A comparative study.

OBJECTIVE: We aim to present our experience with the bidirectional Glenn (BDG) in patients less than 4 months of age and to compare their outcomes with the patients who underwent BDG after the age of 4 months. METHODS: A retrospective review of data was performed for patients who underwent the BDG procedure from 2002 to 2018 at our institutions. We reviewed the patients' demographics, echocardiographic findings, cardiac catheterization data, operative details, postoperative data, and outcome variables. RESULTS: The study was conducted on 213 patients. At the time of the BDG operation, 32 patients were younger than 4 months (younger group) and 181 patients were older than 4 months (older group). The preoperative mean pulmonary artery pressure was significantly higher in the younger group (p = .035) but there were no significant differences between both groups in Qp/Qs, ventricular end-diastolic pressure, indexed pulmonary vascular resistance, and preoperative oxygen saturation. However, the initial postoperative oxygen saturation of the younger group was lower than the older group (p = .007). The duration of mechanical ventilation, duration of pleural drainage, ICU stay, and hospital stay after BDG were significantly longer in the younger group compared to the older group. The early mortality was higher in the younger group, but this difference did not reach statistical significance (p = .283). CONCLUSION: Performing BDG procedure in infants less than 4 months of age is safe, with favorable outcomes. Early BDG is associated with a less-smooth postoperative course without a significant increase in early or late mortality.

Surgical repair for persistent truncus arteriosus in neonates and older children.

OBJECTIVES: Persistent truncus arteriosus represents less than 3% of all congenital heart defects. We aim to analyze mid-term outcomes after primary Truncus arteriosus repair at different ages and to identify the risk factors contributing to mortality and the need for intervention after surgical repair. METHODS: This retrospective cohort study included 36 children, underwent repair of Truncus arteriosus in the period from January 2011 to December 2018 in two institutions. We recorded the clinical and echocardiographic data for the patients preoperatively, early postoperative, 6 months postoperative, then every year until their last documented follow-up appointment. RESULTS: Thirty-six patients had truncus arteriosus repair during the study period. Thirty-one patients had open sternum post-repair, and two patients required extracorporeal membrane oxygenation. Bleeding occurred in 15 patients (41.67%), and operative mortality occurred in 5 patients (14.7%). Patients with truncus arteriosus type 2 (p = 0.008) and 3 (p = 0.001) and who were ventilated preoperatively (p < 0.001) had a longer hospital stay. Surgical re-intervention was required in 8 patients (22.86%), and 11 patients (30.56%) had catheter-based reintervention. Freedom from reintervention was 86% at 1 year, 75% at 2 years and 65% at 3 years. Survival at 1 year was 81% and at 3 years was 76%. High postoperative inotropic score predicted mortality (p = 0.013). CONCLUSION: Repair of the truncus arteriosus can be performed safely with low morbidity and mortality, both in neonates, infants, and older children. Re-intervention is common, preferably through a transcatheter approach.

The Concept of Do Not Resuscitate for the Families of the Patients at King Abdul-Aziz University Hospital.

AIM: Do not resuscitate (DNR) is an order in medical practice for the patients who are suffering from a grave medical condition, and their life is in danger to end. DNR decision-making varies from one hospital to another. This study is aimed to assess the knowledge of the patients' relatives about DNR concept and their opinion about the DNR decision-making. MATERIALS AND METHODS: This was a nonintervention cross-sectional study conducted, during 2016, among 420 patients' relatives in the Emergency Department at King Abdul-Aziz University Hospital in KSA. Data were collected by interviewing the participants. Data were further analyzed using SPSS software. The Chi-square test was used to determine the associations. RESULTS: Variation in responses related to the DNR concept was observed. Around 44% of participants thought that DNR involved maximum intervention in the hospital, including intensive care. Further, the majority (55.2%) of the participants were assured about the quality of the services the patient would receive. Furthermore, 51% of the participants believed that ultimately, it should always be the doctor who decides on a DNR decision. Meanwhile, 36.4% of the relatives opined that the family members should be involved in the discussion regarding the DNR order. CONCLUSION: We observed a gap in the understanding of the concept and decision-making of DNR-order among the participants. Health-care providers should provide a greater explanation about DNR orders to the families of the patients to avoid any misunderstandings, and also support them psychologically to avoid any stress they might encounter in such situations.

The Concept of Do Not Resuscitate for Students in King Abdulaziz University Hospital.

INTRODUCTION: Do not resuscitate (DNR) is a medical procedure for patients who are suffering from critical, untreatable, and irreversible disease where the patient's life is predicted to end. DNR is considered a sensitive decision for patients and their relatives, as well as physicians. AIM: This study is aimed to assess the knowledge and attitude of medical students and interns toward the DNR order and the factors affecting their attitude at the King Abdulaziz University Hospital (KAUH) in Jeddah. METHODS: Nonintervention cross-sectional study was conducted among 429 medical students (preclinical and clinical years) and interns who were given an online questionnaire between May and June in 2016 at KAUH in 18 Kingdom of Saudi Arabia. RESULTS: Our study indicates that most of the participants (73.2%) were familiar with DNR order; however, more than half of them (58.3%) did not take any lecture or session on DNR. Large proportion of medical students had the opinion that attending a lecture or session on DNR would help them discuss it more skillfully with the patients and their relatives. More than half of the participants (55%) believed that there is a Fatwa that regulates DNR on the Islamic level. CONCLUSION: Participants, who were interns, were more familiar with the term DNR, whereas the 2nd-year medical students were less familiar with DNR. Considering the variation in the knowledge of participants about DNR, we conclude that additional lectures and sessions about DNR should be added to the medical school curriculum to make the students more confident and able in handling the DNR discussions.
