Naegleria fowleri, the causative agent of Primary Amoebic Meningoencephalitis (PAM), is commonly found in warm freshwater environments and can enter the brain through nasal passages during activities like swimming or ablution. PAM has a high fatality rate, raising concerns about its global health impact. In Pakistan, particularly in Karachi, a significant number of cases have been reported, often with no history of recreational water exposure, but with regular ablution using tap water.

Campylobacter is a major cause of foodborne gastroenteritis worldwide, with the mishandling of contaminated chicken meat among the main pathways for human infection. Granted the disease burden due to this pathogen, systematic assessments of its potential impact are necessary. The aims of this study were to evaluate both presence and load of Campylobacter in chicken meat sold in traditional markets, assess risk factors related with the infrastructure and hygienic conditions of market stalls, and evaluate control strategies for campylobacteriosis in Peru through a quantitative microbiological risk assessment (QMRA), a data-driven, systematic approach to quantitatively assess risks by integrating empirical contamination levels, microbial behavior, and consumer exposure.

Acrylamide has high hydrophilic properties due to the presence of hydrophilic amide functional groups and is frequently used to synthesize superabsorbents. However, the toxic and carcinogenic properties of acrylamide have caused environmental concerns. The main goal of this paper is the synthesis of superabsorbent with high water absorption from biodegradable and biocompatible cellulose polymer containing amide groups in the backbone of it instead of grafting harmful acrylamide monomers to cellulose.

The identification of ClO and iron ions in water medium is a difficult task and has been one of the hot issues in analytical chemistry. For this objective, we synthesized carbon nanoparticles (CNPs) through a solvothermal reaction between 1, 3, 5-trimesic acid and o-phenylenediamine, which served as a sequential fluorescent probe for ClO and Fe ions. The obtained CNPs were spherical particles with a diameter of 26.

Various types of water can be used to flush enteral feeding tubes, which raises the question of which type of water is best supported by evidence.
Purpose: The aims of this quality improvement project were to examine the evidence on the use of tap water instead of sterile water for enteral tube flushes and to implement the use of tap water as a safe, cost-effective alternative to sterile water at a multisite oncology institution.
