RESUMO
BACKGROUND: Endothelial dysfunction is related to the reduced bioavailability of nitric oxide (NO) and plays a significant role in developing hypertension. The intake of a diet rich in antioxidants decreases the threat of hypertension. Cissus quadrangularis possesses antioxidant, anti-inflammatory, and hypocholesterolemic activities. However, to date, no studies have been performed to explore this plant's antihypertensive and vasorelaxant activity. Herein, we investigated the chronic effect of C. quadrangularis on blood pressure as well as vascular function in hypertensive rats. METHODS: Male spontaneously hypertensive rats (SHR) were randomly divided into two groups. Normotensive Wistar rats were taken as the control group. The treatment was done using ethanolic extract of C. quadrangularis (EECQ) at a dose of 200 mg/kg. RESULTS: The administration of EECQ for six weeks reduced the systolic blood pressure, mean arterial blood pressure, and heart rate. It also alleviated the cardiac and renal hypertrophy indices. Supplementation of EECQ improved the endothelium-dependent aortic vasodilation induced by acetylcholine. It restored the NO level and endothelial NO synthase expression in the aorta. Subsequently, the extract alleviates the oxidative stress and inflammatory markers in SHR rats. CONCLUSION: Thus, in the present study, the chronic treatment of EECQ to genetically hypertensive rats improved endothelium-dependent relaxation in addition to its antihypertensive effect by eNOS activation and inhibition of ROS production, inflammation.

BACKGROUND: Intimate Partner Violence (IPV) is the most common form of violence in conflict and post-conflict settings, but there are few evaluations of interventions to prevent IPV in such settings. METHODS: The Women for Women International (WfWI) intervention is a year-long combined economic and social empowerment intervention for marginalized women survivors of conflict. Primarily, it seeks to support women to achieve four key outcomes: women earn and save money; women improve their health and well-being; women influence decisions in their homes and communities; women connect to networks for support. The organization recognizes Violence Against Women and Girls (VAWG) as a significant barrier to women's empowerment and expects to see reduction in VAWG, and specifically IPV, as part of building women's social and economic empowerment. This program is being quantitatively evaluated through an individually randomized control trial amongst women in Afghanistan, with a 24-month follow up. A comparison of baseline characteristics of participants is also included as well as a discussion of implementation of the baseline research. DISCUSSION: There is a high demand amongst Afghan women for such interventions, and this posed challenges in completing the randomization and baseline. In addition, the complex security situation in Afghanistan also posed challenges. However, despite these issues, recruitment was successfully achieved and the arms were balanced on socio-demographic measures. The evaluation will contribute to the limited evidence base on interventions to prevent IPV in conflict-affected settings. TRIAL REGISTRATION: NCT03236948 . Registered 28 July 2017, retrospectively registered.

Background Lipid profile components play a role in predicting the development of cardiovascular disease and hence mortality, but recent studies have shown mixed results in the older population. The aim of our study was to investigate the association between levels of lipid profile components with all-cause mortality and cardiovascular outcomes among older adults in a primary care setting in Riyadh, Saudi Arabia. Methods A retrospective cohort study was performed among 485 individuals aged 60 years and older who visited the family medicine clinics linked to a tertiary care hospital during the first six months of 2010. The electronic charts of the participants were reviewed up to April 2022 to gather relevant data. Each lipid profile component, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TGs), was categorized into four quartiles. LDL was calculated using the Friedewald formula. Cardiovascular outcomes included ischemic heart disease (IHD), heart failure (HF), and stroke. Results The mean follow-up period was 12 years. The elderly participants with the lowest HDL-C quartile (<1.1 mmol/L) were at higher risk of all-cause mortality (adjusted hazard ratio of 2.023 (95% CI 1.21-3.38)) and IHD (adjusted hazard ratio 3.2 (95% CI 1.6-6.2)). High TC (≥5.7 mmol/L) was associated with an increased risk of HF (adjusted hazard ratio 2.1 (95% CI 1.1-4.0)). Conclusion In patients aged 60 years and older, low HDL-C (<1.1 mmol/L) was associated with a higher risk for all-cause mortality and IHD, and high TC was associated with an increased risk of having HF. No significant association was found for LDL-C, TC, and TGs with all-cause mortality.
RESUMO
OBJECTIVES: To determine the level of awareness of medical law among healthcare practitioners and to identify factors that influence that level of awareness in Saudi Arabia. METHODS: This cross-sectional study was carried out in Riyadh, Saudi Arabia in 2020-2021 via a survey including 750 healthcare practitioners, from different specialties including all regions in Saudi Arabia. Participants included consultants, senior registrars, interns, and residents. RESULTS: Majority of enrolled healthcare practitioners had poor awareness of medical law (approximately 97%). Only 1.5% had adequate awareness of medical law, and only 1.5% had moderate awareness. Factors associated with increased medical law awareness were the age group between 25 and 34, being from the central region, and having a clinical practice for less than 10 years p-value of <0.05. CONCLUSION: Awareness of medical law among healthcare practitioners is limited in Saudi Arabia. Professional medico-legal education should be part of required competencies for undergraduate and postgraduate levels of medical education. Health care practitioners must be educated with laws and regulations of practicing health professions in the country.

BACKGROUND: In July 2015, King Faisal Hospital Family Medicine clinics (KFH-FMC) successfully implemented a paperless, fully integrated, electronic healthcare system. The aim of this study is to evaluate the impact of moving to a fully integrated electronic medical record system, with clinical decision support (CDS) systems, on the quality of healthcare services in a primary care setting. We aim to evaluate the impact of CDS on clinical outcomes such as screening and diagnosis of breast and colorectal cancers, as well as the management of chronic diseases such as diabetes and hypertension, and the uptake of immunizations. INCLUSION AND EXCLUSION CRITERIA: Our study included all adult patients, over the age of 18, registered in the Family Medicine clinic linked to King Faisal Hospital, seen between January 2012 and December 2018. DESIGN: Retrospective cohort study. SETTING: Family Medicine clinics at King Faisal Hospital (KFH-FMC). MATERIALS AND METHODS: Data were collected retrospectively from the electronic health records of all adult patients above 18 years of age, who were seen in KFH-FMC between January 2012 and December 2018. We analyzed several processes of care and a number of clinical outcomes, comparing results for the three and a half years before CDS implementation with the three and a half years after implementation. Data collected included blood pressure measurements, lipid levels, HbA1c for diabetic patients, screening tests done, including PAP smear, mammogram, fecal occult blood tests, and bone densitometry. Other data included cancer diagnoses and immunizations received. RESULTS: Significant increases were found in adult vaccine uptake ranging from an 11-fold increase in influenza uptake, to a 22-fold increase in pneumococcal 23 uptake. The uptake of all the cancer screening tests increased (FOB 66%, mammogram 33%, PAP smear 16%). Diagnoses of breast and colorectal cancer showed significant increases. Breast cancer diagnoses increased from 2 to 14, and colorectal cancer from 3 to 11. No significant improvement was found in chronic disease outcomes. DISCUSSION: The electronic health record with CDS led to significantly improved uptake of immunizations and screening tests, with earlier diagnoses of breast and colon cancer. Evidence of improvement in chronic disease outcomes is still lacking.
RESUMO
Introduction: We assessed whether the Women for Women International (WfWI) economic and social empowerment programme could reduce women's experiences of intimate partner violence (IPV) and depression in Afghanistan. Methods: We conducted a two-arm individually randomised controlled trial in six urban and peri-urban communities. Communities were selected by WfWI for being conflict affected and showing signs of economic vulnerability (eg, little or no education, living in extreme poverty). Individual eligibility were female, aged 18-49, able to consent to participate and one woman per household. At 22 months, three primary outcomes were assessed: past year physical IPV experience; past year severe IPV experience; depressive symptoms. There was no blinding to arms. We conducted an intention-to-treat analysis, controlling for age. We also conducted qualitative interviews at endline, analysed using thematic analysis. Results: 1461 women (n=933 married) were recruited and randomised. Retention at endline was n=1210 (82%). Primary outcomes were in the hypothesised direction, but showed no significant impacts: physical IPV (adjusted OR (aOR) 0.88 (0.62 to 1.23)), severe IPV (aOR 0.75 (0.50 to 1.11)) and depressive symptoms (ß -0.35 (-1.19 to 0.48)). Women reported reduced food insecurity (ß -0.48 (-0.85 to -0.12)), higher earnings (ß 3.79 (0.96 to 6.61)) and savings (ß 11.79 (9.95 to 13.64)). Women reported less gender-inequitable attitudes (ß -0.89 (-1.15 to -0.62)), more household decision-making (ß 0.35 (-0.04 to 0.74)) and increased mobility (aOR 1.78 (1.27 to 2.50)). Twenty-eight in-depth interviews were conducted. Conclusion: The intervention did not impact IPV or depression. The intervention did improve livelihoods, create more gender-equitable relationships and increase women's mobility. Translating these gains into IPV and depression reduction is critical. Trial registration number: NCT03236948, registered 2 August 2017.

AIMS: Recent findings have instituted the role of hyperglycemia-related AGE/RAGE and NF-κB in instigating reactive oxygen species (ROS) mediated mitochondrial dysfunction and apoptosis of hepatocyte, which leads to steatohepatitis. Naringin, a flavanone glycoside found to possess myriads of pharmacological benefits along with its antioxidant and anti-inflammatory properties. Consequently, we aimed to decipher the effect of naringin on RAGE/NF-κB mediated mitochondrial apoptosis in type 2 diabetes mellitus (T2DM)-induced steatohepatitis. MAIN METHODS: Hepatic HepG2 cells were cultured in palmitic acid medium with and without naringin. Lipid content was examined by Oil Red O and Nile Red staining. Cellular apoptosis was determined by Annexin V-FITC/PI staining. An experimental T2DM-induced steatohepatitis was developed in Sprague Dawley rats by high-fat diet (HFD) for 12 weeks. The naringin was administrated orally at a dose of 100 mg/kg, daily for eight weeks. Glucose and insulin tolerance test was performed. Liver sections were stained by hematoxylin-eosin and picrosirius red. The mRNA and protein expression of RAGE and NF-κB were determined by qPCR, Immunofluorescence, and Immunoblotting. Mitochondrial membrane potential (MMP), cellular and mitochondrial ROS were measured by FACS. KEY FINDINGS: Palmitic acid encountered HepG2 cells and HFD fed rats exhibited hyperlipidemia, insulin resistance, abnormal aminotransferases, steatosis, and fibrosis. Besides, the level of AGEs, RAGE, NF-κB, and oxidative stress were exacerbated. Moreover, MMP, cellular and mitochondrial ROS were altered in diabetic rats. Nevertheless, the naringin treatment ameliorated the steatohepatitis by improving the levels of aforementioned parameters. SIGNIFICANCE: Collectively, these findings suggested anti-steatohepatitis potential of naringin in diabetics.

OBJECTIVES: Becoming an Orthopaedic Surgeon is a challenge worldwide. This study attempted to determine the level of training at which orthopaedic surgery is chosen as a career by residents and graduates of Gulf Cooperation Council (GCC) countries. The reasons for choosing this surgical speciality and barriers faced by residents were also explored. METHODS: In this cross-sectional study, a questionnaire was electronically distributed to all GCC orthopaedic surgery residents. All currently enrolled residents and fellows in orthopaedic surgery programmes in KSA, Oman, Kuwait, and Bahrain were invited. Exclusion criteria included first-year residents and those who had completed their residencies before 2013. RESULTS: A total of 275 out of 569 residents responded, a response rate of 48.33%. More than half of the participants (54.5%) chose orthopaedic surgery during their undergraduate studies. Personal interest ranked number one at 61.09%, while parental pressure was found to be the least important reason (0.36%). The majority (88.0%) agreed that orthopaedic surgery was physically demanding, whereas 33.1% wanted to quit orthopaedic surgery. The interest of residents for future subspecialities was mostly in paediatric orthopaedics and sports medicine, as suggested by 16.4% and 16.0%, respectively. CONCLUSION: This study showed an alarming number of residents who wanted to quit orthopaedic surgery. The challenges residents faced were burnout, lack of time, limited exposure to teaching hospitals, and limited seats for subspeciality training. We recommend increasing the number of orthopaedic surgery subspeciality fellowships, as well as the number of fellowship seats in training programmes. The well-being of orthopaedic surgery residents should also be given consideration.
RESUMO
OBJECTIVE: To determine the frequency of Hepatopulmonary Syndrome (HPS) in patients with cirrhosis of the liver. STUDY DESIGN: Observational cross-sectional study. PLACE AND DURATION OF STUDY: Department of Gastroenterology and Hepatology, Shaikh Zayed Hospital, Lahore, from April 2005 to March 2006. PATIENTS AND METHODS: Fifty consecutive patients admitted with liver cirrhosis were recruited. Twelve patients were excluded due to inadequate echocardiography image quality and inability to perform lung function tests. The diagnosis of cirrhosis was made on clinical, biochemical, serological and metabolic workup, ultrasound abdomen or liver biopsy. Complete blood count, liver function tests, prothrombin time, serum albumin, electrocardiography, chest radiograph, transthoracic contrast echocardiography, arterial blood gas analysis and pulmonary function tests (FEV1) were performed. Results were analyzed as percentages. Chi-square test of proportions and t-test were applied. RESULTS: Total patients evaluated were 38. Mean age was 47.92 +/- 11.38 years, with male (68.4%) to female (31.6%) ratio of 2.1:1. The commonest cause of cirrhosis was hepatitis C (71.1%). Out of the 38 patients, 11 (28.9%) had HPS including 5 (13.2%) with overt HPS and 6 (15.8%) with subclinical HPS. All patients with HPS had hepatitis C with Child-Pugh-Turcotte (CPT) class C. Factors associated with HPS were digital clubbing, arterial hypoxemia and intrapulmonary vascular dilatations (p=0.02, 0.05 and 0.000 respectively). CONCLUSION: In this study, 28.9% patients with cirrhosis of the liver had HPS. All belonged to child class C due to hepatitis C. Digital Clubbing, arterial hypoxemia and intrapulmonary vascular dilatations were important features of hepatopulmonary syndrome.

Efficient process of litigation of medical errors is a key to ensure fair, speedy, and accessible justice system. The conditions of establishing medical negligence are similar in both legal systems. These conditions include the duty of care, breach of that duty of care, the damages, and establishing causation. A culture of litigation and compensation is growing in the United Kingdom and Kingdom of Saudi Arabia; however the cost of medical claims and awarded compensations are much more in the United Kingdom compared to Kingdom of Saudi Arabia. In Kingdom of Saudi Arabia, there is a need for more transparency in the documentation and publication of litigated medical errors. In addition, there is a need to introduce interventions to shorten the duration of litigation in both legal systems. Financial caps on awarded compensation and caps on expert and legal fees are potential strategies to control the cost of medical errors which seems to work well in the Saudi model.
