Emergence of Undetectable Malaria Parasites: A Threat under the Radar amid the COVID-19 Pandemic?

Rapid diagnostic tests (RDTs) play a critical role in malaria diagnosis and control. The emergence of parasites that can evade detection by RDTs threatens control and elimination efforts. These parasites lack or have altered genes encoding histidine-rich proteins (HRPs) 2 and 3, the antigens recognized by HRP2-based RDTs.

Oculopalatal tremor following sequential medullary infarcts that did not cause hypertrophic olivary degeneration.

Background: The syndrome of oculopalatal tremor is a known consequence of lesions in the dentate-olivary pathway. Hypertrophic degeneration of the inferior olive is a recognized pathological correlate of these lesions and hypothesized to cause tremorogenic olivary hypersynchrony. However, oculopalatal tremor also occurs in Alexander disease, which produces severe inferior olive degeneration without intervening hypertrophy.

Serum 25-hydroxyvitamin D fluctuations in military personnel during 6-month summer operational deployments in Afghanistan.

Soldier operational performance is determined by their fitness, nutritional status, quality of rest/recovery, and remaining injury/illness free. Understanding large fluctuations in nutritional status during operations is critical to safeguarding health and well-being. There are limited data world-wide describing the effect of extreme climate change on nutrient profiles.

Completely Endoscopic Approach Using a Skeeter Drill to Treat Bilateral Congenital Choanal Atresia in a 33 Week Born Pre-term Baby.

Choanal atresia (CA) is a relatively rare condition manifesting with respiratory distress. Endoscopic approaches have superseded transnasal and transpalatal approaches. We present a case of a premature baby of 1.

Daily Physical Activity Is Associated with Subcortical Brain Volume and Cognition in Heart Failure.

Cognitive impairment in heart failure (HF) is believed to in part stem from structural brain alterations, including shrinkage of subcortical regions. Fortunately, neurocognitive dysfunction in HF can be mitigated by physical activity (PA), though mechanisms for this phenomenon are unclear. PA is protective against age-related cognitive decline that may involve improved structural integrity to brain regions sensitive to aging (e.

Wrist-Worn Accelerometer-Brand Independent Posture Classification.

Introduction: Access to raw acceleration data should facilitate comparisons between accelerometer outputs regardless of monitor brand.

Purpose: To evaluate the accuracy of posture classification using the Sedentary Sphere in data from two widely used wrist-worn triaxial accelerometers.

Methods: Laboratory: Thirty-four adults wore a GENEActiv and an ActiGraph GT3X+ on their nondominant wrist while performing four lying, seven sitting, and five upright activities.
