Introduction: This consensus statement gives practical advice for the safe management of patients with harmful alcohol intake undergoing elective and emergency surgery. The wide spectrum of alcohol-related organ dysfunction observed in this cohort of patients may have a profound impact on care, and the additional effects of alcohol withdrawal may further exacerbate postoperative morbidity and mortality.
Methods: A working party was assembled based on clinical and/or academic expertise in the area.
Contribution of Travelers to Malaria in South West Delhi, India: Cross-Sectional Survey.
JMIR Public Health Surveill
January 2025
Background: India is committed to malaria elimination by the year 2030. According to the classification of malaria endemicity, the National Capital Territory of Delhi falls under category 1, with an annual parasite incidence of <1, and was targeted for elimination by 2022. Among others, population movement across states is one of the key challenges for malaria control, as it can result in imported malaria, thus introducing local transmission in an area nearing elimination.

- The paper combines density functional theory (DFT) and experimental methods to study the properties of undoped and Er-doped lithium tantalate (LiTaO:Er) as fluorescent probes.
- DFT calculations include electronic and optical properties, with specific attention to the effects of Er doping at 4.167 mol. %, using both generalized gradient approximation and hybrid functional methods for accuracy.
- Experimental techniques like X-ray diffraction, Scanning Electron Microscopy, and photoluminescence confirm the synthesis and properties of LiTaO:Er nanoparticles, highlighting strong emissions in visible and near-infrared areas, closely aligning with theoretical predictions.
Ultrasound (US) plays a primary role in the assessment and diagnosis of renal and ureteral pathologies and their management. It is considered the first-line imaging modality for evaluation of urinary obstruction, nephrolithiasis, and urinary retention among other indications. US is also essential for evaluation of renal vasculature and assessment of renal transplantation.

- Intravenous contrast-enhanced ultrasound (CEUS) enhances ultrasound imaging with microbubble contrast agents for better visualization of blood vessels and organ perfusion.
- CEUS is recognized as an effective tool in specific situations and is preferred over traditional B-mode and Doppler imaging.
- The article explores both approved and off-label uses of CEUS for children and adults, including FDA-approved contrast agents, their side effects, and current advancements in the technology.
