We aimed to identify modifiable behavioral risk factors for ARI among infants in a tropical, resource-limited setting. This prospective cohort study enrolled healthy term infants (∼2 months old) at Songklanagarind Hospital. The primary exposures included four modifiable factors during the first 6 months of life: exclusive breastfeeding, bottle-feeding, pacifier usage, and passive smoking. We used multiple Poisson regression models to identify factors associated with the frequency of ARI between 6 and 12 months of age. A cohort of 671 infants was enrolled, of whom 271 (40.3%) experienced at least one episode of ARI between 6 and 12 months of age, with the majority (69.7%) experiencing only one episode. Infants who were bottle-fed during the first 6 months of life had a higher risk of ARI compared with those who were not [incidence rate ratio (IRR) = 1.37, 95% confidence interval (CI): 1.05-1.82, P = .025], and the risk increased with longer duration of bottle use. A similar trend was observed with pacifier use, which was associated with an increased risk of ARI (IRR = 1.33, 95% CI: 1.02-1.71, P = .031). While most participants were breastfed and exposed to passive smoking during the first 6 months, no significant associations with ARI were identified. Bottle-feeding and pacifier use were associated with 37% and 33% increases in risk of ARI, respectively.

This study aimed to identify independent predictors of critical deterioration in hospitalized children with confirmed scrub typhus. A retrospective observational cohort study was conducted at a tertiary-care teaching hospital in South India over 6 years. Children aged 1-14 years with immunoglobulin M enzyme-linked immunosorbent assay-confirmed scrub typhus were included. Critical deterioration, a pre-specified composite of shock, acute respiratory distress syndrome, multiple organ dysfunction syndrome, mortality, or high-flow respiratory support requirement, constituted the primary outcome. Independent predictors were identified by multivariable logistic regression, and discriminatory performance was assessed by area under the receiver operating characteristic curve (AUROC). One hundred and eighty-one children were enrolled (median age 6.0 years; 50.3% male). Critical deterioration occurred in 62 children (34.3%), with a case fatality rate of 12.9% among those affected. Serum albumin demonstrated the highest univariable discriminatory performance (AUROC 0.973), followed by neutrophil-to-lymphocyte ratio (NLR) (0.945), total bilirubin (0.929), and lactate dehydrogenase (0.902). Four variables independently predicted critical deterioration on multivariable analysis: NLR [adjusted odds ratio (aOR) 3.811, 95% confidence interval (CI): 2.119-6.857; P < .001), C-reactive protein (CRP) (aOR 1.052, 95% CI: 1.018-1.089; P = .003), doxycycline delay (aOR 1.829, 95% CI: 1.146-2.920; P = .011), and serum sodium (aOR 0.689, 95% CI: 0.523-0.909; P = .008).

NLR, CRP, serum sodium, and doxycycline delay independently predict critical deterioration in paediatric scrub typhus at hospital admission, with serum albumin demonstrating the highest univariable discriminatory performance.

This nested sub-study of a prospective cohort study was conducted within the public primary healthcare setting in Western Cape, South Africa.

Quantitative data were collected using a predesigned case record form, and caregiver satisfaction was assessed on a pilot 10-point scale. Semistructured face-to-face interviews were conducted for qualitative analysis. Inductive thematic analysis followed Braun and Clarke's framework. A sequential explanatory design with triangulation was employed. Of 6547 admissions, 835 (12.75%) were unplanned discharges; prevalence was higher among neonates than post-neonatal children. Among 139 eligible children (aged 0-12 years), 80 were enrolled (35 neonates, 45 older children). Most families (86%) were from lower socioeconomic strata; 60% received government financial support.

Collective family decision-making occurred in 75% of cases. LAMA was primarily driven by perceived clinical futility rather than financial barriers alone.
