School-Based Epidemiology of Infection in Kharif District of Amran Governorate, North of Yemen: Need for Chemopreventive Strategy Revisiting.

Background: Urogenital schistosomiasis is a persistent public health problem in many rural areas of Yemen. Since 2014, epidemiology has not been assessed in Amran governorate, north of Yemen, where is known to be highly endemic. Therefore, this study determined the prevalence and risk factors associated with infection among schoolchildren in Kharif district of the governorate.

Survival benefit of IABP in pre- versus post-primary percutaneous coronary intervention in patients with cardiogenic shock.

Background: Cardiogenic shock (CS) remains a major cause of in-hospital mortality in the setting of acute myocardial infarction (AMI). However, little evidence is available regarding the optimal order of intra-aortic balloon counter-pulsation (IABP) insertion and primary percutaneous coronary intervention (PPCI). The aim of this study was to assess the hospital and short-term survival benefits of two different IABP insertion approaches, before versus after PPCI in patients with acute myocardial infarction and cardiogenic shock.

Prospective single-center study on the reliability of ipsilateral cerebral oximetry using near-infrared spectroscopy as a predictor for selective shunting during carotid endarterectomy.

Objective: Many techniques are available for the intraoperative assessment of brain perfusion during carotid endarterectomy, such as carotid stump pressure, near-infrared spectroscopy, somatosensory evoked potentials, transcranial Doppler, electroencephalography, and clinical assessment. The decision for selective carotid shunt insertion is dependent on clinical deterioration or the detection of cerebral hypoperfusion after cross-clamping of the internal carotid artery. Monitoring cerebral oximetry using near-infrared spectroscopy is a noninvasive technique for cerebral oxygen saturation measurement, reflecting changes in cerebral blood flow during carotid endarterectomy.

Biochemical compositions and histopathology of the young and aged nymphs of the desert locust Schistocerca gregaria Forsskål (Orthoptera: Acrididae) affected by Photorhabdus luminescens (Enterobacterales: Morganellaceae).

Locusts occasionally represent a danger in Africa despite intensive management measures, leading to severe yield loss and a commensurate loss of food and money. The laboratory assessment of the toxicity of the Photorhabdus luminescens bacteria and its cell-free filtrate used Schistocerca gregaria nymphs in the second and fifth nymphs as test insects. Greater mortality was seen in locust nymphs of the second and fifth instars due to the high levels of toxicity produced by the bacterial suspension and its cell-free filtrate.

Clinical profiles and outcomes of acute ST-segment elevation myocardial infarction in young adults in a tertiary care center in Saudi Arabia.

Objectives: To investigate the clinical profiles and outcomes of young adults presenting with ST-segment elevation myocardial infarction (STEMI).

Methods: We retrospectively reviewed King Saud Medical City, Riyadh, Saudi Arabia, registry between January 2016 and November 2017 for all patients younger than 45 years old who were admitted with STEMI. We compared this study population to a control group of patients aged 45 years and older who were enrolled in the same period.
