BACKGROUND: The Islamic Hajj pilgrimage is the largest annual mass gathering in the world. The overcrowding of people promotes the acquisition, spread and transmission of respiratory pathogens, including Streptococcus pneumoniae. It is estimated that about 33% of pilgrims are at risk of invasive pneumococcal disease. METHODS: We conducted a methodological review according to the Preferred Reporting Items for Systematic Reviews and meta-Analysis guidelines. The objective was to summarize the available data regarding the prevalence of pneumococcal carriage among Hajj pilgrims and about carriage acquisition and circulation of S...

This study was designed to investigate the effect of single-dose radiation therapy (RT) in combination with evofosfamide (TH-302), a hypoxia-activated prodrug, in a pre-clinical model of pancreatic cancer. AsPC1 tumors were implanted orthotopically in the pancreas of nude mice. Tumors were treated with 15 Gy of RT, using a 1 cm diameter field, and delivered as a continuous arc. Image-guidance to center the field on the tumor was based on CT imaging with intraperitoneal contrast. Evofosfamide (100 mg/kg, i.p...

Prion protein (PrP(C)) was initially described due to its involvement in transmissible spongiform encephalopathies. It was subsequently demonstrated to be a cell surface molecule involved in many physiological processes, such as vesicle trafficking. Herein, we investigated the roles of PrP(C) in the response to insulin and obesity development.  Two independent PrP(C) knockout (KO) and one PrP(C) overexpressing (TG20) mouse models were fed high-fat diets, and the development of insulin resistance and obesity was monitored...

The substantial increase in the burden of non-communicable diseases in general and osteoporosis in particular, necessitates the establishment of efficient and targeted diagnosis and treatment strategies. This chapter reviews and compares different tools for osteoporosis screening and diagnosis; it also provides an overview of different treatment guidelines adopted by countries worldwide. While access to dual-energy X-ray absorptiometry to measure bone mineral density (BMD) is limited in most areas in the world, the introduction of risk calculators that combine risk factors, with or without BMD, have resulted in a paradigm shift in osteoporosis screening and management...

Antimicrobial resistance (AMR) is a major threat to human, animal health, and environment worldwide. For human, transmission occurred through a variety of routes both in health-care settings and community. In animals, AMR was reported in livestock, pets, and wildlife; transmission of AMR can be zoonotic with the probably most important route being foodborne transmission. The Indian Ocean Commission (IOC), composed of Comoros, Madagascar, Mauritius, Reunion (France), and Seychelles recognized the surveillance of AMR in both animal and human as a main public health priority for the region...

Multifocus microscopy (MFM) allows sensitive and fast three-dimensional imaging. It relies on the efficient design of diffraction phase gratings yielding homogeneous intensities in desired diffraction orders. Such performances are however guaranteed only for a specific wavelength. Here, we discuss a novel approach for designing binary phase gratings with dual color properties and improved diffraction efficiency for MFM. We simulate binary diffraction gratings with tunable phase shifts to explore its best diffraction performances...

REVIEW
Nady El Hajj, Marcus Dittrich, Thomas Haaf
Protocadherins (Pcdhs) are a group of cell-cell adhesion molecules that are highly expressed in the nervous system and have a major function in dendrite development and neural circuit formation. However, the role protocadherins play in human health and disease remains unclear. Several recent studies have associated epigenetic dysregulation of protocadherins with possible implications for disease pathogenesis. In this review, we briefly recap the various epigenetic mechanisms regulating protocadherin genes, particularly the clustered Pcdhs...

Echinococcus granulosus is the most common tapeworm causing hydatid disease in humans. Its least-encountered complication is cutaneous fistulization. Omentoplasty, cyst, and fistulous tract drainage revealed successful in the management of this complication. Such intervention can be an alternative when conservative management fails, and a minimally aggressive procedure is required.

A key feature of heart failure is adverse extracellular matrix (ECM) remodeling, which is associated with increases in the collagen cross-linking enzyme, lysyl oxidase (LOX). In this study, we assess the progression of cardiovascular remodeling from the compensatory to decompensatory phase, with a focus on the change in LOX expression and activity as it relates to alterations in ECM composition and changes in cardiac function. Adult male Sprague-Dawley rats were studied after 4, 14, or 21weeks of aortocaval fistula-induced volume overload (VO)...

Pancarditis is a rare condition with a poor prognosis combining endocarditis, myocarditis with abscess formation, and purulent pericarditis. Diagnosis is often delayed and the clinical signs are predominantly those of the embolic complications. Literature is scarce. We present a unique and rare case of pancarditis, complicating a Streptococcal B infection in an immunocompetent, healthy, 54 year-old woman. The evolution was favourable under medical therapy alone and thanks to multimodality cardiac imaging diagnosis and follow-up...

BACKGROUND AND PURPOSE: Pharmacotherapy for pain currently involves trial-and-error. A previous study on inherited erythromelalgia (a genetic model of neuropathic pain due to mutations in voltage-gated sodium channel Nav1.7) used genomics, structural modeling, biophysical and pharmacological analyses to guide pharmacotherapy, and showed that carbamazepine normalizes voltage-dependence of activation of the Nav1.7-S241T mutant channel, reducing pain in patients carrying this mutation. However, whether this approach is applicable to other Nav mutations is still unknown...
