Bouveret syndrome is an uncommon condition that leads to gastric outlet obstruction. Diagnosis and treatment may get delayed due to non-specific presentation and rarity of the condition, which is associated with high morbidity and mortality. We present a case of a 62-year-old female who presented with epigastric pain and nausea and was diagnosed with Bouveret syndrome.

We present the case of a nine-year-old male who presented with recurrent bony pain episodes since the age of four, requiring multiple hospital admissions. Initial workup showed anemia, thrombocytopenia, prolonged prothrombin time (PT), partial thromboplastin time (PTT), and elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). The patient underwent an open biopsy of the right femur with irrigation and debridement that was inconclusive, but cultures were positive for methicillin-resistant Staphylococcus aureus (MRSA) and group G hemolytic streptococci that were treated with clindamycin.

Introduction "Code Sepsis" is a protocol, auto-initiated as a system-based trigger in our community-based teaching center. It is designed to be activated in patients with two or more systemic inflammatory response syndrome (SIRS) criteria and organ dysfunction. The purpose is to identify sepsis early and treat it according to the Surviving Sepsis guidelines.

Background: Implantable cardioverter defibrillators (ICD) are battery-operated devices used to manage irregular heart rhythms and deliver therapeutic shocks to the heart. This updated systematic review and meta-analysis compares the efficacy and extraction-related outcomes of single-coil versus dual-coil ICDs in view of conflicting data.

Methods: Several databases, including PubMed, Cochrane Library, and Google Scholar, were comprehensively explored dating from inception to April 1, 2024.

The synthesis, crystal structure, and Hirshfeld surface analysis of -(4-meth-oxy-phen-yl)picolinamide (MPPA), CHNO, are presented. MPPA crystallizes in the monoclinic space group 2/, with a single mol-ecule in the asymmetric unit. Structural analysis reveals that all non-hydrogen atoms are nearly coplanar, and the mol-ecule exhibits two intra-molecular hydrogen bonds that stabilize its conformation.

Issue Addressed: Healthcare access disparities, particularly among migrant populations, are escalating. This research focuses on exploring aspects related to healthcare access disparities in the rapidly growing South Asian communities in Australia, which bear a disproportionate burden of chronic diseases.

Methods: This study employed an exploratory sequential mixed-method approach (qualitative followed by quantitative), with five focus group discussions (six to eight participants each) and an online survey (n = 460).

Hypoparathyroidism is characterized by inadequate parathyroid hormone (PTH) secretion or action and results in hypocalcaemia, and can lead to hyperphosphataemia and hypercalciuria. Most cases of hypoparathyroidism occur as a complication of surgery, with the remainder due to causes including autoimmune disease, genetic causes, infiltrative diseases, mineral deposition or due to abnormalities in serum levels of magnesium. Hypoparathyroidism can cause multisystem disease, with long-term complications resulting from ectopic calcification as well as renal complications with nephrocalcinosis, nephrolithiasis and renal impairment in addition to respiratory, cardiac or neurological manifestations.

Background: Strangulation and hanging injuries are a common form of self-inflicted harm. The incidence of associated blunt cerebrovascular injury and its correlation with clinical findings remains unclear. Furthermore, the decision to image and the choice of imaging remains unresolved.

Background: Immunonutrition supplementation has been shown to reduce the risk of surgical infectious complications; however, its effect on decreasing anastomotic leak rates, in the context of an otherwise robust Enhanced Recovery After Surgery (ERAS) program, remains unclear. This study aims to assess the association between perioperative immunonutrition supplementation and anastomotic leak in an elective Enhanced Recovery After Surgery colorectal surgical population.

Methods: We performed a retrospective single-institution cohort study consisting of adult patients enrolled in an Enhanced Recovery After Surgery pathway and undergoing elective colorectal surgery from 2018 to 2023.

Access, demand, and acceptance of coronavirus disease 2019 (COVID-19) testing have varied globally. This study explored the sociodemographic and psychosocial risk factors that contribute to the uptake of COVID-19 testing in community settings in South Africa. This paper presents a cross-sectional secondary analysis using data from a cluster randomized controlled trial and a nested perception survey of COVID-19 antigen testing in communities located in urban (eThekwini, KwaZulu-Natal) and rural settings (Worcester, Eastern Cape) in South Africa.

Background: Little is known about the burden and outcomes of diverticulitis in patients under the age of 50. This knowledge gap hinders the development of effective management strategies and preventive measures for this population.

Objective: This study aimed to analyze national trends in hospitalizations, interventions, and outcomes for early-onset (age <50) diverticulitis in comparison to standard-onset (age ≥50) cohorts.

Unlabelled: causes melioidosis, a deadly infection having high fatality rates (20-50%) and antibiotic resistance, however, there's no effective drug or vaccine available. Trehalose is a vital sugar for which influences the pathogen resilience and pathogenicity. This proposed computational strategy focuses on developing novel drugs against Trehalose-6-phosphate Phosphatase (TPP) to combat infections.

Stem cell treatment shows promise in treating conditions such as neurodegenerative disorders and spinal injuries, but its effectiveness is hampered by cell death and apoptosis. Improving the differentiation of MSCs into neural cells could enhance their therapeutic potential. The role of miR-22-3p in human dental pulp stem cells (HDPSCs), a superior alternative to treat neurodegenerative disorders, and its molecular mechanisms during neural differentiation remain elusive.

Introduction: Millions of Euvichol-Plus doses have been deployed from the global oral cholera vaccine stockpile in over 20 cholera-affected countries. However, information on Euvichol-Plus's effectiveness is limited. Using this vaccine in a cholera epidemic in Dhaka, Bangladesh, provided the opportunity to evaluate the vaccine effectiveness (VE) using a test-negative design.

Background: Ustekinumab is an effective drug in the treatment of inflammatory bowel disease (IBD), but inadequate response or loss of response is reported in several patients. Dose escalation by intravenous reinduction or interval shortening may be a suitable option to recapture response. We undertook a systematic review and meta-analysis to assess the efficacy of dose escalation in IBD patients receiving ustekinumab.
