Photosensitizer formulations in photodynamic therapy of age-related macular degeneration.

Age-related macular degeneration (AMD) is a progressive degenerative disease that leads to visual impairment, predominantly affecting the elderly. Despite significant advancements in treatment, a definitive cure remains elusive. Current therapeutic strategies only slow down disease progression, inhibiting abnormal blood vessels growth, and preserving or improving vision.

School-age growth and development following infant feeding and/or water, sanitation, and hygiene interventions in rural Zimbabwe: long-term follow-up of a cluster-randomised trial.

Background: Few trials have explored long-term effects of interventions designed to reduce child stunting. We evaluated school-age outcomes in rural Zimbabwean children who received cluster-randomised water, sanitation and hygiene (WASH) and/or infant and young child feeding (IYCF) interventions from pregnancy up to 18 months of age.

Methods: The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial enrolled pregnant women from two rural Zimbabwean districts (Chirumanzu and Shurugwi) between 2012 and 2015, and cluster-randomised them using a 2 × 2 factorial design to standard-of-care, WASH, IYCF, or combined WASH & IYCF, with a co-primary outcome of height-for-age Z-score and haemoglobin at 18 months (clinicaltrials.

Quality of bowel preparation for colonoscopy in patients on glucagon-like peptide-1 receptor agonists.

Background And Aims: We aimed to assess the quality of bowel preparation in a matched cohort of patients actively using and not using glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in a large health system in the United States.

Methods: We performed a retrospective review of adult patients undergoing colonoscopy in 22 endoscopy units across 18 sites in the United States.

Results: Our cohort comprised 6235 patients (3344 case patients and 2891 control patients).

A quasi-experimental study assessing the effectiveness of a community-based egg intervention in the nutritional and health status of young children from rural Honduras.

Objective: This community-public-private-academic coalition project implemented and evaluated the effectiveness of a rural, community-based egg intervention that aimed to support the nutrition and health of children living in rural, poor communities from Intibucá, Honduras, during the COVID-19 pandemic.

Design: This investigator-blind, non-randomized, controlled study was informed by a community health improvement process and participatory research. Women from 13 communities were given a microloan to start an egg farm that supplied 1 egg daily to 201 children ages 6-24 months for 1 year (intervention group).

Bacterial Photodynamic Inactivation: Eradication of and Mediated by Pyridinium-Pyrazolyl Zinc(II) Phthalocyanines.

Antimicrobial resistance remains an enduring global health issue, manifested when microorganisms, such as bacteria, lack responsiveness to antimicrobial treatments. Photodynamic inactivation (PDI) of microorganisms arises as a noninvasive, nontoxic, and repeatable alternative for the inactivation of a broad range of pathogens. So, this study reports the synthesis, structural characterization, and photophysical properties of a new tetra-β-substituted pyridinium-pyrazolyl zinc(II) phthalocyanine (ZnPc ) that was compared with two previously described pyridinium-pyrazolyl ZnPcs and .
