Current situation and barriers to women's leadership in health care education in Saudi Arabia: A cross-sectional study.

Background: The aims of the current study were to explore the true representation of female academic staff who have advanced to leadership positions in Saudi health academic institutions and to determine the possible barriers to women's advancement to leadership positions in academia. Methodology: This was a cross-sectional study conducted between August 2022 and August 2023 using an adapted self-reported online questionnaire via Google form. Data was analyzed descriptively and comparatively by presenting frequencies with percentages besides means with standard deviations across various background categories and comparing them using student t test. Results: A total of 115 educators in health care professions participated in the study, three fifths of them were Saudi and female, with the majority being married and employed by government organizations. The most impactful structural challenges for female leadership included the centralization of decision-making within the institution, unclear organizational bylaws for leadership qualifications and appointment processes, and the existence of a wide range of administrative units. The prevailing belief that men possess superior capacity and management skills compared to women in leadership roles and the reluctance to accept women's authority by their subordinates were identified as the most influential culture challenges for female leadership. Most influential personality-related challenges included difficulty of balancing professional responsibilities with family obligations, stress and tension arising from reconciling the needs of subordinates with organizational goals and the complexity of traveling for work. Conclusions: The study identified the most influential structural, culture, and personality-related barriers and other potential perceived challenges faced by female leadership. A collective effort involving academic institutions, leadership, and relevant stakeholders is critical to address these barriers. Academic institutions must eliminate these challenges to utilize female leaders' talent fully, as they contribute unique perspectives and skills to their institutions.

The Association between Self-Care Activities and Depression in Adult Patients with Type 2 Diabetes in Saudi Arabia: A Cross-Sectional Web-Based Survey Study.

This study examined the level of adherence to self-care behaviors among individuals with type 2 diabetes in Saudi Arabia and its connection with depression and demographic factors. A cross-sectional survey was conducted among diabetes patients using the Patient Health Questionnaire (PHQ-9) to measure depression and the Summary of Diabetes Self-Care Activities (SDSCA) to evaluate diabetes self-care activities. Among the 252 participants who completed the survey, 43.2% were older than 55 and 59% were men. The ordinal regression model showed an association between the PHQ-9 and SDSCA scores with an OR of 0.83 (95% CI: 0.71 to 0.96, p = 0.013). The PHQ-9 score was significantly associated with blood sugar monitoring (OR: 0.90 [95% CI: 0.82 to 0.99, p = 0.003]), exercise (OR: 0.88 [95% CI: 0.79 to 0.98, p = 0.002]), and diet (OR: 0.94 [95% CI: 0.85 to 1.03, p = 0.045]). Of all the diabetes-related factors, only a history of hospitalization and receiving diabetes education were found to be associated with improved self-care behaviors. In conclusion, a negative association was found between PHQ-9 scores and the SDSCA mean score and most daily diabetic self-care behavior components.

An Update on the Effect Of Sodium Glucose Cotransporter 2 Inhibitors on Non-Alcoholic Fatty Liver Disease: A Systematic Review of Clinical Trials.

Non-alcoholic fatty liver disease (NAFLD) is one of the main causes of liver disease, specifically chronic liver disease. Type 2 diabetes (T2DM) is associated with the risk of NAFLD given that patients usually have insulin resistance as one of the observed complications with NAFLD. Hypoglycemic agents, including sodium glucose cotransporter 2 (SGLT-2), have shown to improve NAFLD. The objective of this study is to evaluate the effect of SGLT-2 inhibitors on NAFLD patients' outcomes, whether they have T2DM or not. We conducted a comprehensive search using the PubMed and Ovid databases to identify published studies that addressed the use of SGLT-2 inhibitors in NAFLD patients. The outcomes assessed include changes in liver enzymes, lipid profiles, weight changes, the fibrosis-4-index (FIB4), and magnetic resonance imaging proton density-based fat fraction (MRI-PDFF). Only clinical trials that met the quality measures were included in this review. Out of 382 potential studies, we included 16 clinical trials that discussed the use of SGLT-2 inhibitors in NAFLD patients. A total of 753 patients were enrolled in these trials. The majority of the trials reported positive effects of SGLT-2 inhibitors on liver enzymes; alanine transaminase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transferase. All 10 trials that reported changes in body mass index (BMI) from baseline showed a statistically significant reduction with SGLT-2 inhibitor use, while 11 studies reported a significant increase in high density lipoprotein (HDL) levels, 3 studies reported a reduction in triglycerides (TG) levels, and 2 studies showed a decrease in low density lipoprotein (LDL) levels. The available evidence shows that the use of SGLT-2 inhibitors in NAFLD is associated with positive outcomes on liver enzymes, lipid profiles, and BMI. Further studies with larger sample size and longer follow-up time are warranted.

Research barriers in Saudi pharmacy residency training programs.

Background: The aim of this study is to identify potential barriers to conducting and publishing pharmacy residency research. Methods: A cross-sectional study surveyed pharmacy residents in Saudi Arabia from August to September 2020. The online survey assesses residents' characteristics, residency research experience, barriers to completion, and challenges in publishing. A Likert scale assessed factors and barriers to conducting and publishing research during residency. Descriptive statistics were performed for binary variables, with Likert scale responses visualized using Gannt charts. Results: A total of 69 residents completed the survey, of whom 63.5 percent were female, and the median age was 28 years. More than half of the residents were in R2 (56.5 %), followed by R1 (24.6 %) and R3 (4.4 %). Half of residents had prior research experience, while 84.1 % had prior research training in workshops or courses. Cohort study design was the most common type of residency research project conducted. According to residents, the main barriers to conducting research were a lack of allocated time for research during rotations (81.7 %) and a lack of a realistic timeline determined by the SCFHS to finish the research project (66.2 %). Regarding barriers to publishing research, the majority of residents reported lack of time to work on the publication process (78.6 %), lack of previous publication experience (60 %), and lack of guidance from mentors (55.7 %) as the most important barriers. Conclusion: Pharmacy residents face barriers to conducting research during their residency program, including limited allocated time during rotations, a lack of realistic timelines, and data collection limitations. Additionally, they face challenges in publishing their research due to a lack of experience, mentorship, and guidance. Future research should consider seeking the perspective of residency program directors and preceptors on research barriers and evaluating the publication rate of residents' projects.

Appropriateness of proton pump inhibitors use in noncritically ill hospitalized children in a tertiary hospital in Saudi Arabia.

Background: Studies assessing the appropriate use of proton pump inhibitors (PPIs) for hospitalized noncritically ill pediatric patients are lacking. Therefore, this study aimed to assess the suitability of PPI prescriptions in noncritically ill pediatric patients. Methods: This cross sectional retrospective study was conducted at a maternity hospital in Qassim, Saudi Arabia from November 2020 to January 2021. All noncritically ill hospitalized children aged 14 years and below who received PPIs were included. The endpoints included the number and percentage of patients who appropriately received PPIs in general and in each age category. The collected data were analyzed using Microsoft Excel (version 2208, Microsoft Corp., Redmond, WA, USA). Results: In total, 332 medical records were screened, of which 246 were included. Of all patients, 49.2% were children and 50.8% were infants, with the average age at admission being 5.39 ± 5.4 years years. More than half of the patients were female, and the average weight of patients was 19.8 kg. Omeprazole was appropriately used in 95 (38.5%) patients. Based on age groups, omeprazole was appropriately used in 66.3% of children and 38.4% of infants. Conclusion: The use of omeprazole in noncritically ill pediatrics was only deemed appropriate in 38.6% of the study population. This result indicates that this medication was overused in the institution. Additional research is required to confirm this on a nationwide scale.

Metformin use among obese patients with prediabetes in Qassim, Saudi Arabia: An observational study.

Background and aims: The high prevalence of prediabetes and diabetes mellitus and its secondary complications in Saudi Arabia is a major healthcare concern. Evidence suggests that despite evidence-based efficacy and safety, metformin is underutilized in prediabetic obese patients. Thus, the aim of this study was to investigate the use of metformin in prediabetic obese patients in the Qassim region of Saudi Arabia. Methods: Prediabetic patients' electronic health records were accessed and screened from 2017 to 2021. The inclusion criteria were patients with obesity (BMI ≥ 35) diagnosed with prediabetes, and who received metformin. Patients with chronic kidney disease and those using metformin for other diseases were excluded. The first major endpoint of this study was the rate of metformin use among obese, prediabetic individuals. The second major endpoint was the factors associated with metformin prescribing in our cohort. Descriptive statistics were used to report the primary and secondary outcomes. Data are presented as percentages, means, standard deviations (SDs), medians, and interquartile ranges, as appropriate. All analyses were conducted using Stata version 16.1. Results: A total of 304 prediabetic patients were included in this study after screening the records of 1,789 patients. The average age was found to be 40, and the majority were female (72%). The average BMI was found to be 39.4 kg/m2, while the average HbA1c was 5.8%. In the entire sample, only 25 (8.22%) obese patients received metformin for diabetes prevention. Among obese patients with a BMI ≥ 30, 19 patients (8.7%) received metformin. Metformin users had higher odds of being on statins (OR 2.72, 95% CI 1.01 to 7.36; p = 0.049). Conclusion: According to the study, metformin is not frequently prescribed to prediabetic obese individuals in the Qassim region of Saudi Arabia. This prevention strategy is a missed opportunity in the management of prediabetes in high-risk patients. Future studies are needed to investigate the root causes of the underuse of metformin and potential interventions to promote evidence-based practice in Saudi Arabia.

Types, trends, and patterns of the reported antimicrobial errors to the eastern region's medical centers in Saudi Arabia: A cross-sectional study.

Introduction: Medication errors (MEs) are a huge burden on any healthcare system and have been associated with significant morbidity and mortality. The medical literature reported heavily on MEs but lacked focus on analyzing high-risk medications such as antimicrobials. Research design and methods: This was a retrospective analysis of the MEs database reported by the eastern region's medical centers in Saudi Arabia from January 1, 2019 to December 31, 2019. We used descriptive analysis to identify most common antimicrobials with errors, the stage of antimicrobial errors, type of the errors, contributing factors to the errors, and categories of errors based on the National Coordinating Council for Medication Error Reporting and Prevention (NCC-MERP) classification of errors. Results: A total of 1422 (22.1%) antimicrobial errors were identified out of 6412 MEs. Amoxicillin/Clavulanate (18%) was the most common antimicrobial reported in the database. Most errors occurred in the prescribing phase (87.6%) and included mainly incorrect doses (32.1%) and duplicate therapy (20.5%). In addition, most errors were identified as category B (72.5%). Finally, inexperienced personnel (57.9%) was the most cited contributing factor. Conclusion: This study revealed that antimicrobial errors occur primarily during prescription and that policy gaps and inexperienced staff were contributory factors. To improve, the focus should shift to physician education, clear dosing guidelines, efficient workload management, and implementing antimicrobial stewardship programs to promote appropriate antimicrobial use.

Comparative effectiveness of glucagon-like peptide-1 receptor agonists for the management of obesity in adults without diabetes: A network meta-analysis of randomized clinical trials.

Tirzepatide is a new glucagon-like peptide-1 receptor agonist (GLP-1RA) that has shown promising results for weight loss. A Bayesian network meta-analysis was conducted to compare the efficacy and safety of GLP-1RAs for obesity management. Embase and MEDLINE were searched looking for randomized clinical trials (RCTs) that evaluated the efficacy of GLP-1RAs for weight loss in patients without diabetes. The main efficacy outcomes evaluated were the mean change in actual and percentage weight loss and the proportion of patients with weight loss of ≥5%-20%. Main safety outcomes evaluated include nausea, vomiting, diarrhea, constipation, loss of appetite, pancreatitis, gallbladder-related disorders, and withdrawal due to adverse events. Seven RCTs with more than 12,300 patients were analyzed, including patients with body mass index (BMI) ≥ 30 kg/m2 , or BMI ≥ 27 kg/m2 with comorbidities. Weekly tirzepatide 10 and 15 mg resulted in more weight loss than weekly semaglutide 2.4 mg, daily semaglutide 0.4 mg, or liraglutide 3 mg. Tirzepatide and weekly semaglutide demonstrated comparable results but with significantly higher odds of achieving ≥5%-20% weight loss compared with liraglutide. GLP-1RAs triggered more gastrointestinal adverse events than placebo, with no in-between difference. Although all GLP-1RAs lead to significant weight reduction, tirzepatide was associated with better efficacy outcomes while having a comparable safety profile.

The use of metformin for type 2 diabetes prevention: Observational multicenter study from Saudi Arabia.

Background: Patients with prediabetes are at higher risk of developing type 2 diabetes. While intensive lifestyle modification is the primary approach to delaying diabetes, metformin has been shown to be effective, especially among patients younger than 60 years and obese (body mass index (BMI) > 35 kg/m2), patients with fasting blood glucose ≥ 6.1 mmol/L or HbA1c ≥ 6%, and women with history of gestational diabetes. Thus, metformin is now recommended as an option for diabetes prevention by the American Diabetes Association (ADA). The use of metformin among patients with prediabetes in Saudi Arabia and their adherence to the guideline's recommendation for the prevention of type 2 diabetes is unknown. This study aimed to identify the prevalence of metformin use among prediabetes patients overall and patients who are more likely to benefit from metformin use per the ADA guidelines. Methods: A retrospective cohort study was conducted encompassing data from three tertiary care hospitals between January 2015 and June 2019. All patients aged 20 to 70 years with prediabetes (HbA1c of 5.7-6.4%) were included, while patients with an established diagnosis of diabetes, creatinine clearance <45 ml/min, using antihyperglycemic medications other than metformin, or on metformin for other indications were excluded. Prediabetes patients who are most likely to benefit from metformin for type 2 diabetes prevention are those younger than 60 years with a BMI ≥ 35 kg/m2, patients with fasting blood glucose ≥ 6.1 mmol/L or HbA1c ≥ 6%, and women with history of gestational diabetes. This study examined the prevalence of metformin use among all patients with prediabetes, as well as patients who would be more likely to benefit from metformin use per the ADA guidelines. Results: A total of 251 patients were included in this study; 52.2% were female, with a mean age of 47.0 (11.9) years and BMI of 32.3 (6.5) kg/m2, and the median HbA1c at baseline was 5.8% (5.7-6.0). Among the overall sample, 18 patients (7.2%) received metformin for the prevention of type 2 diabetes, 14 of those were from the groups that are more likely to benefit from metformin use per the ADA guidelines (9.9%). Conclusions: Among individuals with prediabetes in Saudi Arabia, metformin use was very low despite the evidence supporting its safety, convenience, and efficacy. Healthcare providers seemed hesitant to medicalize prediabetes; furthermore, the low use of metformin suggests the existence of several barriers that need to be identified and resolved. Increasing providers' knowledge and awareness regarding screening and management of prediabetes is highly encouraged.

Drug absorption in bariatric surgery patients: A narrative review.

Background: Despite the increase in the number of bariatric surgeries performed, little is known about the impact of the surgery on drug absorption. Unpredictability is assumed with drugs, given the anatomical changes after surgery. Objective: To evaluate the impact of bariatric surgery on drug absorption based on the type of procedure performed. Methods: We conducted a comprehensive literature review searching PubMed/Medline for published studies (from inception to December 2017) that evaluate the use of drugs and the assessment of drug absorption after bariatric surgery. Pharmacokinetic/pharmacodynamic studies, case reports, and observational studies were included in our review. Results: We found 60 studies addressing drug use after bariatric surgery. Twenty-eight studies reported a decrease in drug absorption after bariatric surgery while only four studies showed an increase in drug absorption. Unchanged absorption of drugs was seen in 23 studies after the surgery. Conclusion: The available information shows variations in drug absorption after bariatric surgery. The unpredictability may result from factors related to the patient, drug, and/or type of surgery. Therefore, pharmacists' involvement and close monitoring of patients after bariatric surgery could be effective to avoid sub-/supratherapeutic responses.

Parents' Hesitancy to Vaccinate Their 5-11-Year-Old Children Against COVID-19 in Saudi Arabia: Predictors From the Health Belief Model.

Data exploring parents' hesitancy to vaccinate their 5-11-year-old children against COVID-19, and associated factors, is limited. This study aims to investigate parents' beliefs and intentions to vaccinate their 5-11-year-old children using the Health Belief Model in Saudi Arabia. A national, cross-sectional, questionnaire-based study was conducted in November, 2021. The self-administered online questionnaire was distributed to a random sample of parents. Adult parents with at least one 5-11-year-old child were included. The main outcome was parents' intention to vaccinate their 5-11-year-old children. Variability in parents' intention was assessed by demographics, COVID-19-related factors, children's health status, and constructs from the Health Belief Model. Univariate and multivariable logistic regression were used to investigate each factor and adjust for the intervariable effect on parental intention to vaccinate their children. Of the 4,135 participants, 61.9% were hesitant to vaccinate their 5-11-year-old children. Parents aged 31 to 40 years (OR = 1.23; 95% CI, 1.02-1.49) and females (OR = 1.52; 95% CI, 1.25-1.84) had higher odds of being hesitant to vaccinate their children than parents from other groups. Parents who perceived low benefit from the vaccine (OR = 16.3; 95% CI, 12.1-21.9) or who had safety or efficacy concerns (OR = 3.76; 95% CI, 3.10-4.58) were among the most hesitant to vaccinate their children. In conclusion, vaccine hesitancy is prevalent among parents of 5-11-year-old children in Saudi Arabia and those who had beliefs of minimal benefits or lack of safety from the COVID-19 vaccine were more hesitant. Government efforts must be directed toward increasing parents' vaccine awareness and tackling the constructs of the Health Belief Model through a well-designed vaccination campaign.

Comparative Risk of Acute Kidney Injury Following Concurrent Administration of Vancomycin with Piperacillin/Tazobactam or Meropenem: A Systematic Review and Meta-Analysis of Observational Studies.

The study aims to comparatively assess the nephrotoxicity of vancomycin when combined with piperacillin-tazobactam (V + PT) or meropenem (V + M) in adult patients hospitalized in general wards or intensive care units. We searched MEDLINE, Google Scholar, and Web of Science for observational studies evaluating incidences of AKI in adult patients receiving V + PT or V + M for at least 48 h in general wards or intensive care units. The primary outcome was AKI events, while the secondary outcomes were hospital length of stay, need for renal replacement therapy (RRT), and mortality events. The odds ratio (OR), or mean difference for the hospital length of stay, with a corresponding 95% confidence interval (CI) from the inverse variance weighting random-effects model were estimated for the risk of AKI, RRT, and mortality. Of the 112 studies identified, twelve observational studies were included in this meta-analysis with a total of 14,511 patients. The odds of having AKI were significantly higher in patients receiving V + PT compared with V + M (OR = 2.31; 95%CI 1.69-3.15). There were no differences between V + PT and V + M in the hospital length of stay, RRT, or mortality outcomes. Thus, clinicians should be vigilant while using V + PT, especially in patients who are at high risk of AKI.

Incidence of Diabetic Ketoacidosis Among Pediatrics With Type 1 Diabetes Prior to and During COVID-19 Pandemic: A Meta-Analysis of Observational Studies.

Background: Previous reports suggest that the Coronavirus Disease-2019 (COVID-19) pandemic might have affected incidences of diabetic ketoacidosis (DKA) and new diagnoses of type 1 diabetes. This systematic review and meta-analysis aimed to estimate the risk of DKA, including severe DKA, during the COVID-19 pandemic versus the prior-to-COVID-19 period among pediatric patients with type 1 diabetes. Methods: PubMed and EMBASE were searched for observational studies investigating the risk of DKA among pediatric patients with type 1 diabetes during the COVID-19 pandemic and the prior-to-COVID-19 period. A random meta-analysis model was performed to estimate the relative risk of DKA during the COVID-19 pandemic compared to before the pandemic. Subgroup analyses were conducted based on the type 1 diabetes status, established or newly diagnosed. In addition, sensitivity analysis was conducted for studies that reported results from adjusted analysis for potential confounders using fixed effect model. Results: A total of 20 observational studies reported the risk of DKA, of which 18 reported the risk of severe DKA. The risks of DKA and severe DKA were 35% (RR 1.35, 95%CI 1.2-1.53, I2 = 71%) and 76% (RR 1.76, 95%CI 1.33-2.33, I2 = 44%) higher in the during-COVID-19 group compared to the prior-to-COVID-19 group, respectively. Among patients with newly diagnosed type 1 diabetes, the risk of DKA was 44% higher for the during-COVID-19 group compared to the prior-to-COVID-19 group (RR 1.44, 95%CI 1.26-1.65; I2 = 64%). Only two studies reported the risk of DKA among patients with established type 1 diabetes and the cumulative risk was not statistically significant. In the sensitivity analysis, four studies reported an adjusted odds ratio (aOR) of the risk of DKA during COVID-19 compared to the prior-to-COVID-19 period. The fixed estimate from the meta-analysis found an increase in the risk of DKA in the during-COVID-19 group compared to the prior-to-COVID-19 group (aOR 2.04, 95%CI 1.66-2.50). Conclusions: This study showed that DKA risk, especially the risk of severe DKA, has increased significantly during the pandemic. Healthcare systems must be aware and prepared for such an increase in DKA cases and take all necessary measures to prevent future spikes during the pandemic.

Characteristics of the ideal clinical pharmacy residency candidate: A survey of residency program directors and preceptors in Saudi Arabia.

OBJECTIVE: Residency positions are highly competitive. Pharmacy students who are familiar with the ideal qualities of residency candidates and the expectations of residency programs may be more likely to obtain one of these coveted positions. This study identifies the characteristics that residency program directors (RPDs) and preceptors use to define an ideal residency candidate. METHODS: This is a cross-sectional, descriptive study that surveyed pharmacy RPDs and preceptors across the Kingdom of Saudi Arabia. The questionnaires are comprised of two sections: demographic information and characteristics of the residency candidates. Over a five-month period (May 1, 2020 - September 30, 2020), the survey was sent electronically to the participants. RESULTS: Of the 78 surveys returned, 68 surveys were included (RPDs: 36, Preceptors: 32) and 12 surveys (15.17%) were excluded due to incompleteness. Number of RPDs responded to the survey represents (65%) of the total RPDs in Saudi Arabia. The mean response scores from the results of the Likert scale [strongly agree (1) - strongly disagree (5)] - suggest that a candidate's performance during the interview (mean score = 1.5), their professional appearance (1.5), an alignment between a candidate's interests and the program focus (1.6), and previous hospital experience (1.8) mattered most. While being from the same region (3.4), having an advanced degree (2.8) and the cumulative Grade Point Average (2.7) mattered the least. We find that previous hospital experience (29%), familiarity with the program (16%), research experience (15%), Saudi Commission for Health Specialists aggregate score (10%), and letters of recommendation (4%) are considered the top five factors. CONCLUSION: Residency candidates should focus on training in clinical settings. Offering mock interviews and Saudi Pharmacist Licensure Examination practice tests and involving pharmacy students in clinical research may increase their chance in securing a residency position.

The use of direct oral anticoagulants for thromboprophylaxis or treatment of cancer-associated venous thromboembolism: a meta-analysis and review of the guidelines.

BACKGROUND: Venous thromboembolism (VTE) is a common complication among patients with cancer and is one of the most common causes of increased morbidity and mortality. The use of direct oral anticoagulants (DOACs) for thromboprophylaxis and treatment of cancer-associated venous thromboembolism (CA-VTE) has been evaluated in several randomized clinical trials (RCTs). The aim of this meta-analysis was to assess efficacy and safety of using DOACs for thromboprophylaxis and treatment of CA-VTE and provide a summary for available guidelines' recommendations. METHODS: MEDLINE was searched to identify studies evaluating the use of DOACs for thromboprophylaxis or treatment in patients with cancer. Search was limited to peer-reviewed studies published in English. Studies were excluded if they were not RCTs or subgroup analyses of data derived from RCTs, if they did not report efficacy and safety data on patients with active cancer, or if they were published as an abstract. New VTE or VTE recurrence, and major or clinically relevant non-major bleeding (CRNMB) were used to assess the efficacy and safety, respectively. The Mantel-Haenszel random-effects model risk ratios (RRs) and the corresponding 95% confidence intervals (CIs) were calculated to estimate the pooled treatment effects of DOACs. RESULTS: Four studies evaluating DOACs use for thromboprophylaxis and four - for treatment of CA-VTE were included. Thromboprophylaxis with DOACs was associated with a significant reduction in the risk of symptomatic VTE (RR = 0.58; 95%CI 0.37,0.91) but with an incremental risk of major bleeding or CRNMB (RR = 1.57; 95%CI 1.10,2.26). CA-VTE treatment with DOACs was linked with a significant reduction in VTE recurrence (RR = 0.62; 95%CI 0.44,0.87) but with an incremental risk of CRNMB (RR = 1.58; 95%CI 1.11,2.24). CONCLUSIONS: The DOACs are associated with a lower risk of symptomatic VTE and VTE recurrence, but the risk of bleeding remains a considerable concern. Clinical decisions should be made by assessing individual patient's risk of VTE and bleeding.

Real-World Effectiveness and Safety of Apixaban versus Warfarin in Patients with Acute Venous Thromboembolism: Experience of a Large Tertiary Hospital in Saudi Arabia.

PURPOSE: The main objective of this study was to evaluate the effectiveness and safety of apixaban versus warfarin in patients with venous thromboembolism (VTE) in a "real-world" setting. PATIENTS AND METHODS: A retrospective cohort study was conducted using data from a large tertiary hospital in Saudi Arabia. Patients were included if they were adults (≥18 years), diagnosed with VTE, and treated with either apixaban or warfarin between January 2016 and September 2018. Patients who had received anticoagulation therapy within three months of the date of the index event were excluded. The effectiveness outcomes were incidence of VTE recurrence (ie, deep vein thrombosis DVT or pulmonary embolism [PE]), while the safety outcome was incidence of any major bleeding (MB) event within 90 days of follow-up. RESULTS: Among the 492 patients included for study, 212 (43.1%) received apixaban and 280 (56.1%) received warfarin. The mean age of patients was 53.6±19.1 years and 62% of the cohort was female. Comparable rates of VTE recurrence were observed for apixaban and warfarin treatment groups during follow-up (adjusted odds ratio (AOR) =0.95; 95% CI 0.53-1.68), including DVT (AOR=1.06; 95% CI 0.52-2.17) and PE (AOR=0.78; 95% CI 0.31-1.96). However, apixaban was associated with significantly fewer MB events than warfarin (AOR=0.18; 95% CI 0.04-0.83). CONCLUSION: The use of apixaban for the treatment of Saudi patients with acute VTE is associated with a VTE recurrence rate comparable to that of warfarin, with significantly fewer MB events.

Safety and effectiveness of thromboprophylaxis use in hospitalized elderly medical patients at a Saudi tertiary care center.

INTRODUCTION: Appropriate prescribing of thromboprophylaxis according to guidelines' recommendations can heighten over- or underutilization risk. The study intended to evaluate the safety and effectiveness of appropriate/inappropriate thromboprophylaxis use among hospitalized elderly medical patients. METHODS: A retrospective observational cohort study was conducted, including patients who were ≥60 years old, hospitalized for an acute medical illness that required hospitalization in a medical ward for >48 h, and received thromboprophylaxis. Against the American College of Chest Physicians guidelines, the thromboprophylaxis use appropriateness was assessed. RESULTS: A total of 370 patients met the inclusion criteria, in 71.9% of whom thromboprophylaxis use was appropriate. The mean age of the included patients was 75 years (±9.1), and 72.4% of them were at high risk of venous thromboembolism (VTE), and almost all these patients received appropriate thromboprophylaxis. The occurrence of bleeding was significantly higher in the appropriate use group during hospitalization than the inappropriate use group (11.7% vs. 2.9%, p = 0.009); the majority of these bleeding events were classified as major. There were no differences in VTE events during hospitalization or 90 days all-cause mortality between the two groups. CONCLUSION: The study demonstrates high prescribers' compliance with recommendations in high-risk patients. In patients at low risk for VTE, the overutilization of thromboprophylaxis did not increase their bleeding risk. This study suggests that the benefits of thromboprophylaxis in elderly patients, regardless of their VTE risk, may outweigh the risk of bleeding.

Heart failure outcomes and glucagon-like peptide-1 receptor agonists: A systematic review of observational studies.

AIM/OBJECTIVE: Recently, the glucagon-like peptide-1 receptor agonists (GLP-1RA) class showed a significant reduction in heart failure (HF) hospitalization in several meta-analyses of cardiovascular outcome trials (CVOTs). The objective of this systematic review is to summarize the real-world evidence regarding HF outcomes of GLP-1RAs. METHODS: We searched the PubMed and EMBASE databases for observational studies that investigated HF outcomes of GLP-1RAs. RESULTS: Our search yielded 10 observational studies. Of those, 7 were cohort studies, and 3 were nested case-control studies. The risk of HF was the outcome in four cohort studies. One study that compared exenatide and exenatide combined with insulin to insulin showed a reduction in HF risk in the exenatide and exenatide plus insulin groups (HR 0.34, 95% CI 0.22-0.52, p-value <0.001 and HR 0.40, 95% CI 0.32-0.50, p-value <0.001, respectively). The other three cohort studies did not show a statistically significant result. In the three cohort studies that investigated HF hospitalization as an outcome, two showed a lower rate of HF hospitalization [48 (16.7%) vs. 76 (28%), p-value <0.05 and HR 0.51, 95% CI 0.34-0.77, p = 0.002] in the GLP-1RA groups. Conversely, the remaining study showed a reduction of 14% in HF hospitalization in the dipeptidyl peptidase-4 inhibitors (DPP-4i) group compared to the GLP-1RA group (HR 0.86, 95% CI 0.83-0.90). In contrast to the cohort studies, the three nested case-control studies showed similar results of no association of GLP-1RA use and HF hospitalization with OR 0.67 (95% CI 0.32-1.42), HR 0.95 (95% CI 0.83-1.10), and OR 0.84 (95% CI 0.48-1.47), respectively. CONCLUSION: The real-world evidence regarding the reduction in HF risk and hospitalization in GLP-1RA users is conflicting. Further well-designed, large multicenter, observational studies are needed to show clearer evidence.

Safety and efficacy of dual versus triple antithrombotic therapy (DAT vs TAT) in patients with atrial fibrillation following a PCI: a systematic review and network meta-analysis.

OBJECTIVE: Creating an appropriate antithrombotic therapy for patients with atrial fibrillation (AF) who have undergone percutaneous coronary intervention (PCI) remains a dilemma. Several clinical trials compared the use of a dual antithrombotic therapy (DAT) regimen with a direct oral anticoagulants including (apixaban, dabigatran, edoxaban or rivaroxaban) and a P2Y12 inhibitor versus a triple antithrombotic therapy (TAT) that includes a vitamin K antagonist plus aspirin and a P2Y12 inhibitor in patients with AF who have undergone PCI. However, there are no head-to-head trials comparing the DAT regimens to each other. We aimed to compare the efficacy and safety of DAT regimens using a network meta-analysis (NMA) approach. DESIGN: A systematic review and NMA of randomised clinical trials. METHODS: We conducted a systematic literature review to identify relevant randomised clinical trials and performed a Bayesian NMA for International Society on Thrombosis and Haemostasis (ISTH) major or clinically relevant non-major (CRNM) bleeding, all-cause mortality, stroke, myocardial infarction (MI) and stent thrombosis outcomes. We used NetMetaXL V.1.6.1 and WinBUGS V.1.4.3 for the NMA and estimated the probability of ranking the treatments based on the surface under the cumulative ranking curve. RESULTS: The comparison between DAT regimens showed no significant difference in the safety or efficacy outcomes. Apixaban regimen was ranked first as the preferred therapy in terms of ISTH major or CRNM bleeding and stroke, with a probability of 52% and 54%, respectively. Rivaroxaban regimen was the preferred therapy in terms of MI and stent thrombosis, with a probability of 34% and 27%, respectively. Dabigatran regimen was ranked first in terms of all-cause mortality, with a probability of 28%. CONCLUSION: The DAT regimens are as safe and effective as TAT regimens. However, ranking probabilities for the best option in the selected outcomes can be used to guide the selection among these agents based on different patients' conditions.
