Risk Factors and Outcomes of Protein-Calorie Malnutrition in Chronic Heart Failure Patients Undergoing Elective Cardiac Surgery.

Introduction: Chronic heart failure (CHF) patients are often malnourished. Our aim was to determine the effect of protein-calorie malnutrition (PCM) on in-hospital outcomes in CHF patients following elective cardiac surgery and to identify risk factors for PCM in this patient population.

Methods: A retrospective analysis of the National Inpatient Sample (NIS) database was conducted from 2016 to 2018.

Acute Myocarditis Masquerading as ST-Elevation Myocardial Infarction in a 17-Year-Old.

Myocarditis can have a variable clinical presentation, ranging from asymptomatic to full-blown fulminant heart failure with severe left ventricular dysfunction or acute coronary syndrome (ACS) even ST-Elevation Myocardial Infarction (STEMI). Clinically myocarditis mimicking STEMI can present physicians with a great diagnostic challenge, especially in the absence of pro-dormal flu-like symptoms or a recent viral illness. Cardiac MRI has demonstrated superiority in detecting myocardial abnormalities and differentiating patients with myocarditis and from those with true STEMI.

Accessibility and Content of Fellowship Programs for Cardiovascular Disease.

Background The objective of this study was to assess the accessibility and content of the Accreditation Council for Graduate Medical Education (ACGME)-accredited general cardiology fellowship websites. Methods Using the online information provided by the Electronic Residency Application Services (ERAS), we compiled a list of ACGME-accredited cardiac fellowship programs. The program links on ERAS were evaluated followed by a standard Google search of the program name + "cardiology fellowship".

A Reinforcement Learning Routing Protocol for UAV Aided Public Safety Networks.

In Public Safety Networks (PSNs), the conservation of on-scene device energy is critical to ensure long term connectivity to first responders. Due to the limited transmit power, this connectivity can be ensured by enabling continuous cooperation among on-scene devices through multipath routing. In this paper, we present a Reinforcement Learning (RL) and Unmanned Aerial Vehicle- (UAV) aided multipath routing scheme for PSNs.

Recurrent Takotsubo Cardiomyopathy Presenting With Anterior Wall ST-Elevation Myocardial Infarction.

Takotsubo cardiomyopathy (TC) or stress cardiomyopathy with the presence of transient apical ballooning of the left ventricle in the absence of obstructive coronary artery disease. The recurrence of TC is extremely rare, with an annual recurrence risk of 1.5% and approximately 5% recurrence risk after six years.

Acute Pulmonary Embolism Presenting With Angina and a Positive Cardiac Stress Test.

Acute pulmonary embolism (PE) is a commonly missed clinical entity. Prompt diagnosis of PE and the initiation of anticoagulation therapy is vital for the reduction of patient mortality. Recognizing initial electrocardiogram manifestations can aid rapid diagnosis and prompt management.

Kir6.1- and SUR2-dependent KATP overactivity disrupts intestinal motility in murine models of Cantú syndrome.

Cantú syndrome (CS), caused by gain-of-function (GOF) mutations in pore-forming (Kir6.1, KCNJ8) and accessory (SUR2, ABCC9) ATP-sensitive potassium (KATP) channel subunit genes, is frequently accompanied by gastrointestinal (GI) dysmotility, and we describe 1 CS patient who required an implanted intestinal irrigation system for successful stooling. We used gene-modified mice to assess the underlying KATP channel subunits in gut smooth muscle and to model the consequences of altered KATP channels in CS gut.

Towards Efficient Wireless Body Area Network Using Two-Way Relay Cooperation.

The fabrication of lightweight, ultra-thin, low power and intelligent body-borne sensors leads to novel advances in wireless body area networks (WBANs). Depending on the placement of the nodes, it is characterized as in/on body WBAN; thus, the channel is largely affected by body posture, clothing, muscle movement, body temperature and climatic conditions. The energy resources are limited and it is not feasible to replace the sensor's battery frequently.

Factors contributing to early menarche in school girls.

Objective: To assess the average age of menarche in Pakistani girls from different socioeconomic backgrounds.

Methodology: This was a cross sectional study design carried out on female students studying in different schools of Karachi in 2014. Girls aged 10-14 years age were included.
