Eosinophilic myocarditis: systematic review.

Objective: In clinical practice, patients with eosinophilic myocarditis (EM) may forgo the gold standard diagnostic procedure, endomyocardial biopsy (EMB), although it is highly recommended in guidelines. This systematic review aims to summarise current approaches in diagnosing and treating EM with a particular emphasis on the utilisation and value of alternative diagnostic methods.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we searched MEDLINE and EMBASE for all peer-reviewed articles using the keywords "eosinophilic myocarditis" from their inception to 10 September 2022.

Elevated circulating monocytes and monocyte activation in COVID-19 convalescent individuals.

Background: Monocytes and macrophages play a pivotal role in inflammation during acute SARS-CoV-2 infection. However, their contribution to the development of post-acute sequelae of SARS-CoV-2 infection (PASC) are not fully elucidated.

Methods: A cross-sectional study was conducted comparing plasma cytokine and monocyte levels among three groups: participants with pulmonary PASC (PPASC) with a reduced predicted diffusing capacity for carbon monoxide [DLCOc, <80%; (PG)]; fully recovered from SARS-CoV-2 with no residual symptoms (recovered group, RG); and negative for SARS-CoV-2 (negative group, NG).

Cerebral toxoplasmosis in a patient with combined variable immunodeficiency.

Background: Cerebral toxoplasmosis is an opportunistic infection in patients but has rarely been described in the setting of compromised humoral immunodeficiency. Prompt diagnosis and treatment of the infection is critical in the care of these patients. Medical management is the mainstay of treatment of the infection.

Impact of Atrial Fibrillation on Patients With Inflammatory Bowel Disease Admitted for Colectomy.

Introduction Inflammatory bowel disease (IBD) is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract. Patients with IBD may undergo a segmental or total colectomy, depending upon the extent of the disease. It is estimated that approximately 20 to 30 percent of patients with advanced ulcerative colitis will eventually require surgical resection.

The efficacy of posterior wall isolation in atrial fibrillation ablation: A systematic review and meta-analysis of randomized controlled trials.

Background: Posterior wall isolation (PWI) is an emerging approach in atrial fibrillation (AF) ablation, yet its efficacy remains controversial. This is the first meta-analysis of randomized controlled trials (RCT) to evaluate the efficacy of PWI in AF ablation.

Objective: To assess the efficacy of PWI in reducing atrial arrhythmia recurrence following initial AF ablation at long-term follow-ups when compared to conventional methods.

Clinical characteristics of BRASH syndrome: Systematic scoping review.

Background: Bradycardia, renal failure, atrioventricular (AV) nodal blockade, shock, and hyperkalemia (BRASH) syndrome is a recently-established entity precipitated by medication-induced AV nodal blockade. Despite its serious consequences, including death, clinical presentations, risk factors, and outcomes of the syndrome have not been well defined. We aim to summarize the existing evidence of BRASH syndrome.

Two Cases of BRASH Syndrome: A Diagnostic Challenge.

Unlabelled: Bradycardia, renal failure, atrioventricular (AV) nodal blockade, shock, and hyperkalemia (BRASH) syndrome is a relatively new clinical entity. It is often underrecognized, underdiagnosed, and confused with other causes of bradycardia. Treatment of BRASH syndrome differs from the standard bradycardia algorithm in advanced cardiac life support (ACLS), and the cornerstone management remains treating the hyperkalemia, improving renal function by treating the underlying cause, withholding AV nodal blocking agents, and considering dialysis in refractory cases, as any single factor could precipitate the vicious cycle.

Association between Mineralocorticoid Receptor Antagonist and Mortality in SARS-CoV-2 Patients: A Systematic Review and Meta-Analysis.

Since the onset of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, various potential targeted therapies for SARS-CoV-2 infection have been proposed. The protective effects of mineralocorticoid receptor antagonists (MRA) against tissue fibrosis, pulmonary and systemic vasoconstriction, and inflammation have been implicated in potentially attenuating the severity of SARS-CoV-2 infection by inhibiting the deleterious effects of aldosterone. Furthermore, spironolactone, a type of MRA, has been suggested to have a beneficial effect on SARS-CoV-2 outcomes through its dual action as an MRA and antiandrogen, resulting in reduced transmembrane protease receptor serine type 2 (TMPRSS2)-related viral entry to host cells.

Gastric Perforation: A Rare Presentation of Malignant Gastric Outlet Obstruction.

Mechanical gastric outlet obstruction (GOO) due to malignancy can occur with cancers in the stomach and duodenum. GOO can cause perforation of the stomach or the esophagus. We present a 65-year-old female with newly diagnosed metastatic pancreatic cancer who presented with acute onset abdominal pain.

Characteristics of Takotsubo cardiomyopathy in patients with COVID-19: Systematic scoping review.

Background: COVID-19 has recently been associated with the development of Takotsubo cardiomyopathy (TCM). This scoping review aims to summarize the existing evidence regarding TCM in COVID-19 and offer future direction for study.

Methods: Following the PRISMA Extension for Scoping Reviews, MEDLINE and EMBASE were searched for all peer-reviewed articles with relevant keywords including "Takotsubo", "Stress-induced cardiomyopathy" and "COVID-19" from their inception to September 25, 2021.

Relationship between optical perfusion pressure and systemic blood pressure on glaucoma: Case-control study.

Aim: To investigate the relationship between blood pressure (BP), ocular perfusion pressure (OPP), intraocular pressure (IOP) and open angle glaucoma (OAG) in Primary Open Angle Glaucoma (POAG) patients and normal population.

Design: Cross-sectional observation study.

Materials And Methods: Hospital-based, case control cross-sectional study conducted on 150 patients, of which 75 people were included in the control group and 75 people in the glaucoma group.
