Proportion of Angle Closure Glaucoma in Tamale, Ghana.

Prcis: In the largest clinic-based study to date, our review of 588 patients presenting with glaucoma in Northern Ghana revealed 36% of these had primary angle closure glaucoma (PACG).

Objective: Glaucoma is the second leading cause of blindness worldwide. In Africa, glaucoma is an established public health problem, and PACG is not commonly discussed.

ConTraNet: A hybrid network for improving the classification of EEG and EMG signals with limited training data.

Objective: Bio-Signals such as electroencephalography (EEG) and electromyography (EMG) are widely used for the rehabilitation of physically disabled people and for the characterization of cognitive impairments. Successful decoding of these bio-signals is however non-trivial because of the time-varying and non-stationary characteristics. Furthermore, existence of short- and long-range dependencies in these time-series signal makes the decoding even more challenging.

The Impact of Electromagnetic Interference from Charging All-electric Vehicles on Implantable Cardioverter-defibrillator Performance.

Electric vehicles (EVs) are growing in popularity and in general use. The effect of electromagnetic interference (EMI) caused by supercharging all-electric vehicles on implantable cardioverter-defibrillator (ICD) function has not been studied. The objective of this study was to determine the extent of the effect of EMI from charging Tesla all-electric vehicles (Tesla, Inc.

Left Ventricular Support for Unprotected Left Main Coronary Artery Interventions (The Dayton Heart and Vascular Impella Registry).

Background: Coronary artery bypass grafting is the standard of care for patients with obstructive left main (LM) coronary disease. In poor surgical candidates, high-risk percutaneous coronary artery intervention (PCI) is an alternative.

Methods: We investigated a retrospective cohort of patients who underwent LM PCI from January 2010 to March 2014 ( = 89).

Enhancing the decoding accuracy of EEG signals by the introduction of anchored-STFT and adversarial data augmentation method.

Brain-computer interfaces (BCIs) enable communication between humans and machines by translating brain activity into control commands. Electroencephalography (EEG) signals are one of the most used brain signals in non-invasive BCI applications but are often contaminated with noise. Therefore, it is possible that meaningful patterns for classifying EEG signals are deeply hidden.

Quantifying the alignment error and the effect of incomplete somatosensory feedback on motor performance in a virtual brain-computer-interface setup.

Invasive brain-computer-interfaces (BCIs) aim to improve severely paralyzed patient's (e.g. tetraplegics) quality of life by using decoded movement intentions to let them interact with robotic limbs.

SpikeDeep-classifier: a deep-learning based fully automatic offline spike sorting algorithm.

Advancements in electrode design have resulted in micro-electrode arrays with hundreds of channels for single cell recordings. In the resulting electrophysiological recordings, each implanted electrode can record spike activity (SA) of one or more neurons along with background activity (BA). The aim of this study is to isolate SA of each neural source.

Correction to: Vitamin D and Heart Failure.

The original version of this article, published in Current Heart Failure Reports, Volume 14, Issue 5, October 2017, erroneously cited an author's name as Marshall Brinkley, D" when it should be "Brinkley, DM."

Vitamin D and Heart Failure.

Purpose: Vitamin D is principally known for its role in calcium homeostasis, but preclinical studies implicate multiple pathways through which vitamin D may affect cardiovascular function and influence risk for heart failure. Many adults with cardiovascular disease have low vitamin D status, making it a potential therapeutic target. We review the rationale and potential role of vitamin D supplementation in the prevention and treatment of chronic heart failure.

Polarizable Material from a Conjunctival Biopsy in a Patient with Sarcoidosis.

Purpose: Conjunctival biopsies may contain polarizable material in patients with sarcoidosis despite no history of prior trauma or eye surgeries.

Procedures: A 39-year-old male with uveitic glaucoma presented with decreased vision and throbbing pain in his right eye. His intraocular pressure was elevated, and his vision was reduced to hand motion.

Out in the cold: the hypothermic heart response.

We present an interesting case of a 49-year-old woman with hypothermia and associated Osborn waves (also called J waves) on ECG. She was found on the floor of her home and difficult to arouse. On arrival to the emergency department (ED), her rectal temperature was 87.

A One-Sided Affair: Unoriginal Origin of the Left Coronary Artery, a Case Report.

Coronary artery anomalies constitute a group of congenital malformations that have a multitude of clinical manifestations and highly variable pathophysiology. We report a 56-year-old male with angina due to an anomalous origin of the left main coronary artery; approach and management.

Bedside cardiac testing in acute cor pulmonale.

We present a case where an ECG and echocardiogram suggested pulmonary embolism and early treatment led to a positive outcome.

Xanthogranulomatous cholecystitis mimicking gallbladder cancer.

Xanthogranulomatous cholecystitis (XGC) is a benign, uncommon variant of chronic cholecystitis characterised by focal or diffuse destructive inflammatory process of the gallbladder (GB). Macroscopically, it appears like yellowish tumour-like masses in the wall of the GB. This article reports on a 74-year-old woman with XGC mimicking GB cancer.

A hiding in the lining: painful pericardial cyst.

A pericardial cyst is a rare and benign congenital malformation, usually discovered in the third or fourth decade of life. Its clinical presentation is variable, as it may be asymptomatic or present with chest pain, shortness of breath, or rarely with cardiac tamponade and arrhythmias. We present an interesting case of a woman presenting with chest pain who was found to have a pericardial cyst.

Platypnea orthodeoxia: a 'laid-back' case of dyspnoea.

A man with end-stage liver disease who presented with shortness of breath. He exhibited clinical platypnea (worsening shortness of breath on sitting up) and orthodeoxia (oxygen desaturation on sitting up). Follow-up investigations led to the diagnosis of hepatopulmonary syndrome.

Anomalous venous circuit: a detour to the heart.

We report a case of a complicated vascular access secondary to systemic venous defects, which have not been previously reported. Evaluation revealed an atypical coursing of a subclavian vein-persistent superior vena caval system into the hemizygos-azygos system and ultimately into the right (proper) superior vena cava. The clinical and surgical considerations of such an anomaly are discussed therein.

Trapdoor ischaemia: coronary ostial occlusion by an aortic dissection.

We present an interesting case of an elderly man with acute myocardial infarction due to retrograde dissection of the aortic root occluding the coronary ostia.

Acute pre-renal failure: acquired chloride diarrhea after bowel resection.

A 58-year old male with a history of small bowel resection and ileostomy presented with severe dehydration and high ostomy output. Laboratory investigation indicated hypochloremia, hypokalemia, hyponatremia, metabolic alkalosis, chloride-rich diarrhea, acute renal failure, and low urinary chloride excretion. Due to striking similarities to congenital chloridorrhea (CCD) reported in neonates, we empirically diagnosed acquired chloridorrhea (ACD, chloride diarrhea).

Assessment of urinary iodine excretion among normal Kuwaiti adults.

This study was performed to investigate the status of iodine intake among the Kuwaiti population and its effect on thyroid function. The study group was comprised of 139 females and 86 males with a mean age of 33 and 35 years, respectively. Urinary iodine excretion (UIE) and serum free T4 (FT4), thyrotropin hormone (TSH), antiperoxidase antibodies (anti- TPOAb), and antithyroglobulin antibodies (anti-TGAb) were determined.
