Background: Sepsis in children is one of the main causes of death in pediatric intensive care units (PICUs); however, the pathogenesis of sepsis is not fully clear. Previous studies revealed that many genetic variations were related to sepsis susceptibility. A long non-coding RNA () may play a role in mitochondrial homeostasis and antioxidative activity, but the relationship between the lncRNA polymorphism and sepsis susceptibility has not been reported.
Methods: In this study, 474 pediatric sepsis patients and 678 healthy controls were recruited from southern China. After genotyping, the strength of the associations was evaluated through odds ratios (ORs) and 95% confidence intervals (CIs).
Results: The rs9839776 T allele was associated with decreased susceptibility to sepsis in southern Chinese children (TT/CT vs CC adjusted OR = 0.778, 95% CI = 0.610-0.992; P = 0.0431). Moreover, the difference in susceptibility was greater in children of age >60 months (adjusted OR = 0.458, 95% CI = 0.234-0.896; = 0.0225), survivors (adjusted OR = 0.758, 95% CI = 0.585-0.972; P = 0.0358), males (adjusted OR = 0.655, 95% CI = 0.479-0.894; P = 0.0077) and the sepsis subgroup (adjusted OR = 0.548, 95% CI = 0.343-0.876; P = 0.0120).
Conclusion: The rs9839776 T allele may contribute to decreased sepsis risk in Chinese children. Future studies with a larger sample size are needed to verify these results.

Background: Klebsiella pneumoniae (Kpn), a WHO priority pathogen with high rates of antimicrobial resistance (AMR), has emerged as a leading cause of hospital acquired pneumonia and neonatal sepsis.
Objective: We aimed to define the clinical characteristics of a cohort of patients with Kpn infection in Dhaka, Bangladesh and to perform phenotypic and genetic characterization of the associated isolates.
Methods: We retrospectively extracted clinical data about patients at Dhaka Medical College Hospital from whom Klebsiella spp was isolated from a clinical specimen collected between February and September 2022.

Bacteremia can easily become severe, and it is necessary to start appropriate treatment quickly before it progresses to sepsis. In this study, we investigated a method using antibiotic discs to quickly report antibiotic resistance information for bacteremia caused by gramnegative bacilli, such as , which require careful selection of appropriate antibiotics due to their tendency to cause severe illness. In cases of bacteremia caused by ESBL and AmpC-producing bacteria, reports of suspected antibiotic resistance mechanisms were made within a few hours after disk placement, allowing for the rapid modification of antimicrobial therapy, thereby contributing to the treatment.

Background: Early detection and treatment of carbapenem-resistant Klebsiella pneumoniae (CRKP) could reduce the risk of developing life-threatening sepsis in childhood. However, little is known about sepsis caused by CRKP in children under-5 in developing countries. This study aimed to determine the epidemiology, antimicrobial resistance profile, associated risk factors and management of CRKP in children under-5 with sepsis in Ethiopia.

Bacterial meningitis causes significant morbidity and mortality in infants. Lumbar punctures are often deferred until the results of blood cultures are known and sometimes not considered, making this population susceptible to a missed diagnosis. There are few studies describing the epidemiology of neonatal meningitis in quaternary neonatal intensive care unit settings.
