Objectives: To investigate the incidence of early-onset neonatal sepsis and identify the main pathogens over a 5-year period in Kuwait.
Methods: Blood samples were collected from all infants with any clinical or laboratory feature suggestive of sepsis, at the main maternity hospital in Kuwait. Cases of early-onset neonatal infection were defined as culture of a single potentially pathogenic organism from blood or cerebrospinal fluid from infants younger than 7 days of age, in association with clinical or laboratory findings consistent with infection.
Results: The overall incidence of early-onset neonatal infection was 2.7 (95% confidence interval (CI) 2.3-3.2) episodes per 1000 live-births. The case-fatality was 13.1% (95% CI 8.6-18.9%). Group B Streptococcus (GBS) accounted for 17.6% of infections among infants younger than 7 days (incidence 0.48 per 1000 live-births), but 38.1% of infections in the first 2 days of life. Neither the incidence of early-onset infection by GBS nor by Escherichia coli changed significantly over the study period.
Conclusions: Although the incidence of GBS infections was relatively low, GBS accounted for most early-onset infections. Intrapartum antibiotic prophylaxis against GBS should be strengthened. There was no evidence to suggest that early-onset infection due to non-GBS organisms such E. coli has increased in the last 5 years.

Notch2 Inhibition and Kidney Cyst Growth in Autosomal Dominant Polycystic Kidney Disease.

Background: Notch signaling, a conserved mechanism of cell-to-cell communication, plays a crucial role in regulating cellular processes such as proliferation and differentiation in a context-dependent manner. However, the specific contribution of Notch signaling to the progression of polycystic kidney disease (PKD) remains unclear.
Methods: We investigated the changes in Notch signaling activity (Notch1-4) in the kidneys of autosomal dominant PKD (ADPKD) patients and two ADPKD mouse models (early and late onset).

Article Synopsis
- Neonatal sepsis is a major cause of newborn deaths in low and middle-income countries, prompting a study in Vietnam to analyze bacterial causes and antibiotic resistance patterns.
- A study at the National Children's Hospital identified 202 cases of sepsis, predominantly caused by Gram-negative bacteria, with Klebsiella pneumoniae as the most common pathogen.
- The research underscores the need for ongoing monitoring and specific antibiotic strategies to effectively address neonatal sepsis and its challenges.

Neonatal diabetes mellitus is a rare disorder with prevalence of one in 400,000 live births that's defined by persistent hyperglycaemia within the first six months of life. Neonatal diabetes is heterogeneous and can be transient or permanent. Developmental delay, Epilepsy and Neonatal Diabetes (DEND) syndrome is characterised by developmental delay, epilepsy, and neonatal diabetes.

Background: Identification of predictive biomarkers is crucial for formulating preventive interventions and halting the progression of atopic march. Although controversial, the use of accessible markers to predict or detect early onset of atopic diseases is highly desirable. Therefore, this study aimed to investigate whether corneal squamous cell carcinoma antigen-1 (SCCA1) collected from infants can predict the development of atopic dermatitis and food allergy.

To investigate the effects of early-onset sepsis (EOS) on retinopathy of prematurity (ROP) in extremely premature infants (EPIs) by using propensity score matching (PSM). Clinical data of 591 EPIs admitted to NICU, Senior Department of Pediatric, PLA General Hospital from May 1, 2015 to May 1, 2022 were retrospectively analyzed. They were divided into an EOS group and a non-EOS group according to whether they had confirmed EOS or not.
