In children residing in areas with a high content of a number of aromatic hydrocarbons in ambient air and organochlorine compounds in drinking water there were studied the blood levels of these compounds, as well as the assessment of the indices of the immune and neuroendocrine systems was performed. The higher blood content of phenol and formaldehyde has been established and there was identified an array of organochlorine and aromatic compounds not detected in the control group children. In the blood of the children of a study group there was found an imbalance of indices of cellular components of innate and adaptive immunity, pro- and anti-inflammatory cytokines, as well as increased concentrations of free thyroxine and serotonin in the blood serum, which indicates to a change in the functions of regulatory systems in children exposed to organochlorine and aromatic compounds.

Background: Noise-induced hearing loss (NIHL) in children is a growing public health concern due to increased exposure to high noise levels in various environments. Early intervention is crucial to prevent long-term developmental and social impacts. This study evaluates the effectiveness of earmuffs as a protective intervention in managing NIHL in children.

Objectives: Sudden unexpected infant death (SUID) occurs disproportionately among opioid exposed newborns (OENs) compared to those unexposed. The extent that primary caregivers of OENs adhere to SUID-reducing infant care practices is unknown. We examined rates of SUID-reducing practices (smoking cessation, breastfeeding, and safe sleep [supine sleep, room-sharing not bed-sharing, nonuse of soft bedding or objects]) in a pilot sample of caregivers of OENs.

Background: Environmental factors are increasingly being recognized as significant contributors to Alzheimer's and Related Dementias (ADRD). Previously, we reported that higher serum concentrations of DDE, the highly persistent metabolite of the pesticide DDT was associated with increased risk of Alzheimer's disease. We further demonstrated in cell and animal models that DDT and DDE increase amyloid pathology in the brain (Fig.

Aga Khan University, Nairobi, Kenya.
Background: Population growth and an increase in the number of Africans who survive to old age puts them at a higher risk of developing neurodegenerative diseases such as dementia and Alzheimer's. Little research has been conducted on community knowledge and perceptions of dementia in rural settings in Kenya.
Method: Community health volunteers, healthcare workers (HCWs), chiefs and assistant chiefs (n = 35) participated in five focus group discussions, each comprising seven- eight people.

Antibiotic resistance is one of the most urgent threats to public health. The development of antibiotic resistance can be reduced by the use of narrow-spectrum antibiotics that target specific bacteria, meaning that fewer non-harmful bacteria are killed and other harmful bacteria are not exposed to selection pressure. However, many narrow-spectrum antibiotics were introduced decades ago and therefore lack regulatory documentation in line with current standards.
