Parasitology Unit, Department of Microbiology and Molecular Genetics, the Kuvin Center for the Study of Infectious and Tropical Diseases, The Hebrew University-Hadassah Medical School, Jerusalem, Israel.

Scabies, caused by the Sarcoptes scabiei var hominis mite burrowing into the skin, is a highly contagious disease characterized by intense nocturnal itching. Its global impact is considerable, affecting more than 200 million individuals annually and posing significant challenges to healthcare systems worldwide. Transmission occurs primarily through direct skin-to-skin contact, contributing to its widespread prevalence and emergence as a substantial public health concern affecting large populations.

June 2024

Department of Prosthodontics, Hadassah Medical Center, Faculty of Dental Medicine, Hebrew University of Jerusalem, In Partial Fulfillment of DMD Requirements, Hebrew University-Hadassah School of Dental Medicine, Jerusalem 91120, Israel.

Article Synopsis
  • Sugary drinks can contribute to dental decay, but sugar-free options like Coca-Cola Zero Sugar (CZ) may seem safer; this study investigates CZ's impact on cavity-causing bacteria and tooth enamel.
  • In the experiment, enamel slabs were exposed to biofilms of Streptococcus mutans and treated with either CZ, hydrochloric acid, or sugar solutions; results showed that CZ supported bacterial growth and lowered pH, indicating harm to the enamel.
  • The findings suggest that sugar-free drinks like CZ might still promote tooth decay, warning dental professionals to inform patients that these beverages can be as damaging to dental health as their sugary counterparts.

The subthalamic nucleus (STN) is pivotal in basal ganglia function in health and disease. Micro-electrode recordings of >25,000 recording sites from 146 Parkinson's patients undergoing deep brain stimulation (DBS) allowed differentiation between subthalamic input, represented by local field potential (LFP), and output, reflected in spike discharge rate (SPK). As with many natural systems, STN neuronal activity exhibits power-law dynamics characterized by the exponent α.

Background: Effective strategies are needed to improve vaccine acceptance. This study sought to determine if a peer-led vaccine education intervention embedded within community medical practices increases parental acceptance of pediatric pneumococcal conjugate vaccination.

Methods: From March 2022-July 2023, we conducted a randomized trial at three pediatric health practices in predominantly Hasidic Jewish neighborhoods in New York, where vaccine deferral is common.

Article Synopsis
  • Understanding how genetic programs influence neuron classification is crucial for nervous system development, with neurons categorized into commissural (crossing midline) and ipsilateral (not crossing) types.
  • We identified transcription factors Nhlh1 and Nhlh2 as key regulators controlling laterality in commissural axons in mice, mediating the expression of Robo3, a guidance molecule.
  • Additionally, Isl1, found in ipsilateral neurons, inhibits Robo3 induction by Nhlh1/2, highlighting a complex interplay between global mechanisms and specific neuron regulators in determining axon paths.

Individuals with Parkinson's disease (PD) may exhibit impaired emotion perception. However, research demonstrating this decline has been based almost entirely on the recognition of isolated emotional cues. In real life, emotional cues such as expressive faces are typically encountered alongside expressive bodies.

In recent years, steady progress has been made in synthesizing and characterizing engineered nanoparticles, resulting in several approved drugs and multiple promising candidates in clinical trials. Regulatory agencies such as the Food and Drug Administration and the European Medicines Agency released important guidance documents facilitating nanoparticle-based drug product development, particularly in the context of liposomes and lipid-based carriers. Even with the progress achieved, it is clear that many barriers must still be overcome to accelerate translation into the clinic.

Antibiotic-resistant pathogens are a growing global issue, leading to untreatable infectious diseases in both humans and animals. Personalized bacteriophage (phage) therapy, the use of specific anti-bacterial viruses, is currently a leading approach to combat antibiotic-resistant infections. The implementation of phage therapy has primarily been focused on humans, almost neglecting the impact of such infections on the health and welfare of companion animals.

Children with congenital or acquired asplenia or hyposplenism have an increased risk for severe and even life-threatening infections mainly due to encapsulated bacteria. Current practice focuses on preventing severe infections with timely administration of vaccinations, antibacterial prophylaxis when indicated, and urgent evaluation and treatment of febrile events. As new vaccines are now available for both children and adults with asplenia/hyposplenism, we present an up-to-date recommendation on the prevention and management of acute infections in children with asplenia/hyposplenism.
