Hypertrophic Cardiomyopathy Diagnosis and Treatment in High- and Low-Income Countries: A Narrative Review.

Hypertrophic cardiomyopathy (HCM) is a hereditary cardiac condition characterized by unexplained left ventricular hypertrophy without a hemodynamic cause. This condition is prevalent in the United States, resulting in various clinical manifestations, including diastolic dysfunction, left ventricular outflow obstruction, cardiac ischemia, and atrial fibrillation. HCM is associated with several genetic mutations, with sarcomeric mutations being the most common and contributing to a more complex disease course.

Superior Mesenteric Artery Dissection After Lumbar Puncture.

We hereby present a case of iatrogenic dissection of the superior mesenteric artery dissection in a 63-year-old female undergoing a lumbar puncture (LP). She presented with severe diffused abdominal pain accompanied by lower back pain, nausea and vomiting a few hours after undergoing an LP due to ongoing headaches. Abdominal CT showed evidence of hemoperitoneum.

Apixaban versus enoxaparin for thromboprophylaxis after hip replacement.

Background: There are various regimens for thromboprophylaxis after hip replacement. Low-molecular-weight heparins such as enoxaparin predominantly inhibit factor Xa but also inhibit thrombin to some degree. Orally active, specific factor Xa inhibitors such as apixaban may provide effective thromboprophylaxis with a lower risk of bleeding and improved ease of use.

Melatonin exerts a more potent effect than S-adenosyl-l-methionine against iron metabolism disturbances, oxidative stress and tissue injury induced by obstructive jaundice in rats.

Melatonin and S-adenosyl-l-methionine (SAMe) prevent oxidative stress and tissue dysfunction in obstructive jaundice (OJ). Lipid peroxidation is exacerbated in the presence of trace amounts of iron (Fe). The study investigated the regulation by melatonin and SAMe the induction of oxidative stress, iron metabolism disturbances and tissue injury in an experimental model of OJ.

Melatonin prevents brain oxidative stress induced by obstructive jaundice in rats.

The aim of the study was to analyze the impact of melatonin on brain oxidative stress in experimental biliary obstruction. Cholestasis was done by a double ligature and section of the extrahepatic biliary duct. Melatonin was injected intraperitoneally (500 microg/kg/day).

Efficacy of rifabutin-based triple therapy as second-line treatment to eradicate helicobacter pylori infection.

Background: Rifabutin has been found to be effective in multi-resistant patients after various treatment cycles for Helicobacter pylori (HP) infection, but it has not been analysed as a second-line treatment. Therefore, we seek to compare the effectiveness of a treatment regimen including rifabutin versus conventional quadruple therapy (QT).

Methods: Open clinical trial, randomised and multi-centre, of two treatment protocols: A) Conventional regime -QT- (omeprazole 20 mg bid, bismuth citrate 120 mg qid, tetracycline 500 mg qid and metronidazole 500 mg tid); B) Experimental one -OAR- (omeprazole 20 mg bid, amoxicillin 1 gr bid, and rifabutin 150 mg bid), both taken orally for 7 days, in patients with HP infection for whom first-line treatment had failed.
