Background: Hospital-acquired infection is higher among healthcare workers (HCWs) than among other occupational groups, and the COVID-19 pandemic exacerbated its incidence.
Aim: To assess the incidence of hospital-acquired infections among HCWs in, Cairo, Egypt, during the COVID-19 pandemic.
Methods: This retrospective cohort study collected and evaluated data on hospital-acquired infections (excluding COVID-19) from 1660 nurses, physicians, technicians, and housekeepers in 6 hospitals in Cairo Governorate, Egypt, 1 year before and 1 year during the COVID-19 pandemic.
This paper presents a comprehensive analysis of the impact of adaptive cruise control on energy consumption in real-world driving conditions based on a natural experiment: a large-scale observational dataset of driving data from a diverse fleet of vehicles and drivers. The analysis is conducted at two different fidelity levels: (1) a macroscopic trip-level benefit estimate that compares trips with and without cruise control in a counterfactual way using statistical methods, and (2) a situation-based comparison achieved through the segmentation of trips into distinct driving situations such as acceleration, braking, cruising, and other maneuvers. The results of this research show that the effect of cruise control on energy consumption varies across different driving situations and levels of analysis.

The aim of our work was to assess the value of STE in the diagnosis of subclinical ventricular dysfunction and as a prognostic index in sepsis patients.
Patients And Methods: An observational prospective study involving critically ill patients aged ≥ 18 years diagnosed with sepsis or septic shock.
Article Synopsis
- The CRISPR/Cas system is a powerful genome-editing tool used in biomedical research to manipulate genes associated with both normal and disease functions, known for its efficiency and specificity.
- Key challenges in its therapeutic applications include safe delivery to target cells and minimizing off-target effects, which can be addressed by understanding anti-CRISPR proteins (Acrs) that can inhibit the CRISPR/Cas system.
- Acrs operate through various mechanisms, and recent research on their action can enhance the safe use of CRISPR/Cas technologies, potentially leading to advancements in gene therapy, diagnostics, and antimicrobial treatments.
Article Synopsis
- A study validated a radiomics model that uses MRI imaging to differentiate between lipomas and atypical lipomatous tumors (ALTs), addressing challenges associated with traditional biopsy methods.
- Three cohorts were analyzed: two for external validation from the US and UK and one for prospective validation from the Netherlands, utilizing automatic and interactive segmentation methods for tumor imaging.
- The model demonstrated strong performance with area under the curve (AUC) scores ranging from 0.74 to 0.89, matching or exceeding the diagnostic abilities of expert radiologists.
