Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) became a major concern since the announcement that it is a pandemic in early 2020. Vaccine trials were started in November 2020, and completed rapidly due to the urgency to get over the infection. Side effects to vaccines started to be reported. There were minor side effects including site of injection pain and heaviness and constitutional symptoms like fever which are considered minor. One of the rare adverse events is post vaccine new onset autoimmune diseases. Methods: Data were obtained from one center in the eastern province of Saudi Arabia (King Fahd Hospital of University). All patient events reported occurred in the study period March 2021 to February 2022. We identified patients presenting with autoimmune diseases with exclusively new onset presentations. Results: We identified 31 cases of immune-mediated disease: 18 females (58%); 13 males (42%). Only 4 of them (13%) had an autoimmune background before COVID-19 vaccination. The average time between vaccination and new-onset disease symptoms was 7 days. Among all the cases in our study, 7 patients (22.5%) had new-onset vasculitis, 2 cases had IgA vasculitis and 5 cases had ANCA vasculitis, 6 cases had neurological diseases (19.3%), 4 cases (12.9%) had new-onset systemic lupus erythematosus (SLE), 3 cases (9.6%) presented with new-onset inflammatory arthritis, and one had Sjogren’s syndrome (3.2%). Conclusion: Our study is unique as it is the first study to include the largest number (31 patients) of new onsets of confirmed autoimmune diseases related to Covid-19 vaccines.

Pulmonary embolism (PE) is a common life-threatening condition with non-specific clinical presentations. The diagnosis of PE depends highly on imaging studies, which may also provide prognostic information. This study aimed to describe the clinical and imaging profiles of patients with PE, emphasizing the differences between central and peripheral PE. After ethics review board approval, this retrospective observational study examined the non-negative results in adult patients who underwent computed tomography pulmonary angiography (CT-PA) at our hospital between May 2016 and December 2019. Demographic and clinical information and imaging findings were collected from the electronic medical records. The study included 85 cases that were identified after re-interpreting the 103 non-negative CT-PA scans. Six cases were excluded for incomplete data and 12 cases were false-positive. Central PE was found in 63.5% of the cases. Obesity was the most common risk factor seen in 37.6% of the cases. Furthermore, 9.4% of the patients had sickle cell disease, which tended to be associated with peripheral PE. There was no difference between the peripheral and central PE in most clinical and imaging parameters evaluated (P > 0.05). However, patients with isolated subsegmental PE were more likely to develop hemoptysis (P = 0.04). This study suggests that patients with obesity and sickle cell disease constitute an important proportion of all PE cases. Furthermore, the clinical and imaging profiles in patients with peripheral PE are similar to those in patients with central PE. Future research should focus on the clinical value of peripheral PE in patients with sickle cell disease.

Obesity is a chronic, relapsing disease with multifactorial origins and significant global health implications. Historically, bariatric surgery has been the most effective intervention for achieving sustained weight loss and metabolic improvement, especially in individuals with moderate to severe obesity. However, the therapeutic landscape is rapidly evolving. Recent advances in pharmacotherapy—including GLP-1 receptor agonists, dual and triple incretin agonists, and amylin-based combination therapies—have demonstrated unprecedented efficacy, with some agents inducing 15–25% weight loss, approaching outcomes once exclusive to surgical intervention. These developments challenge the continued applicability of existing bariatric surgery criteria, which were established in an era of limited medical alternatives. In this narrative review, we examine the evolution of surgical eligibility thresholds and critically assess the potential role of novel pharmacotherapies in redefining treatment algorithms. By comparing the efficacy, safety, metabolic benefits, and cost-effectiveness of surgery versus next-generation drugs, we explore whether a more stepwise, pharmacotherapy-first approach may now be justified, particularly in patients with BMI 30–40 kg/m². We also discuss future directions in obesity management, including personalized treatment strategies, perioperative drug use, and the integration of pharmacologic agents into long-term care pathways. As the field advances, a paradigm shift toward individualized, minimally invasive interventions appears inevitable—necessitating a timely re-evaluation of current bariatric surgery guidelines to reflect the expanding potential of medical therapy.

Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading infection that is on the rise. New variants are continuously appearing with variable degrees of lethality and infectivity. The extensive work since the start of the pandemic has led to the evolution of COVID-19 vaccines with varying mechanisms. We aim to determine real-world data by looking at the different clinical outcomes associated with COVID-19 vaccination, focusing on the rate of hospitalization, severity, and mortality. Methodology: A retrospective observational study included 624 patients with COVID-19 infection who were hospitalized at King Fahad Hospital of the University and King Fahad Military Medical City between April and July 2021. The cohort was divided into 3 groups: unvaccinated, partially vaccinated (PV), and fully vaccinated (FV). The severity and outcome of COVID-19 disease were compared among the three groups. Among the vaccinated group, we studied the effect of vaccine type on the severity and outcome of COVID-19 disease. Results: We found that 70.4% of patients with COVID-19 disease who required hospitalization were unvaccinated. Un-vaccination was a significant predictor of critical COVID-19 disease (OR 2.31; P < 0.001), whereas full vaccination was associated with significantly milder disease severity (OR 0.36; P 0.01). Moreover, un-vaccination status was an independent predictor of longer hospitalization (OR 3.0; P < 0.001), a higher requirement for ICU admission (OR 4.7; P < 0.001), mechanical ventilation (OR 3.6; P < 0.001), and death (OR 4.8; P < 0.001), whereas the FV group had a lower risk of ICU admission (OR 0.49; P 0.045). Unvaccinated patients with comorbidities had worse severity and outcome of COVID-19 infection (P< 0.05). Both vaccine types (Pfizer and AstraZeneca) had similar protective effects against the worst outcomes of COVID-19 disease. Conclusion: COVID-19 vaccination has been shown to be effective in reducing hospitalization, the severity of COVID-19 infection, and improving outcomes, especially in high-risk group patients. COVID-19 vaccination programs should continue to improve the outcome of such a disease.

The current pandemic of the novel coronavirus disease 2019 (COVID-19) originated in Wuhan, China in December 2019. The most common clinical manifestations are fever, fatigue, and cough. Other common symptoms include anorexia, chest tightness and shortness of breath. Extrapulmonary manifestations including gastrointestinal symptoms were also reported in patients with COVID-19 infection. It has been found that the ACE2 receptor of SARS-CoV-2 is expressed more in the pancreas than in the lungs. However, only few cases reported with pancreatic injury were caused by COVID-19. In this paper, we report a young patient presenting with acute necrotizing pancreatitis that is complicated with portal vein thrombosis and found to have COVID-19 infection.
