Objective: To measure the frequency of antimicrobial resistance in pediatric blood culture isolates of Escherichia coli and Klebsiella spp. with focus on carbapenem resistance.
Methods: Over a period of three years, pediatric blood culture isolates were tested for antimicrobial susceptibility, including molecular investigations for carbapenem resistance.
Results: Amikacin, carbapenems, colistin and tigecycline had an antimicrobial efficacy of >70% (n=140). 7 of the 15 randomly selected isolates were positive for carbapenemase gene; among them, five were New Delhi Metallo b-lactamase (NDM).
Conclusion: There was a high prevalence of Klebsiella spp. in pediatric bacteremia and dissemination of NDM-mediated carbapenem resistance in pediatric wards.

An alternatively translated isoform of PPARG proposes AF-1 domain inhibition as an insulin sensitization target.

PPARγ is the pharmacological target of thiazolidinediones (TZDs), potent insulin sensitizers that prevent metabolic disease morbidity but are accompanied by side effects such as weight gain, in part due to non-physiological transcriptional agonism. Using high throughput genome engineering, we targeted nonsense mutations to every exon of PPARG, finding an ATG in Exon 2 (chr3:12381414, CCDS2609 c.A403) that functions as an alternative translational start site.

Resective epilepsy surgery can be an effective treatment for patients with medication-resistant focal epilepsy. Epilepsy resection consists of the surgical removal of an epileptic focus to stop seizure generation and disrupt the epileptic network. However, even focal surgical resections for epilepsy lead to widespread brain network changes.

Data regarding Penicillin allergy labels (PALs) from India and Sri Lanka are sparse. Emerging data suggests that the proportion of patients declaring an unverified PAL in secondary care in India and Sri Lanka (1%-4%) is lesser than that reported in High Income Countries (15%-20%). However, even this relatively small percentage translates into a large absolute number, as this part of the world accounts for approximately 25% of the global population.

Background: The two strongest earthquakes in Turkey for eight decades hit Kahramanmaraş province on February 6, 2023. This study aimed to determine psychiatric complaints, acute stress symptoms, anxiety, depression, and sleep characteristics in children who were treated in a tertiary inpatient pediatric unit after the earthquakes. They were evaluated in the fourth week after the earthquake.

Background: The growing demand for esthetic restorative materials highlights the need to evaluate their marginal accuracy and fracture resistance to ensure optimal clinical outcomes for primary molars.
Aim: The aim was to assess the vertical marginal gap distance and fracture resistance of esthetic restorative materials after cyclic loading.
Design: Forty extracted primary molars were randomly divided into four groups: Group I, stainless steel veneered crowns with tooth-colored material; Group II, prefabricated monolithic zirconia crowns; Group III, yttria-partially stabilized zirconia computer-aided design/computer-aided manufacturing (CAD/CAM) crowns; and Group IV, hybrid ceramic CAD/CAM crowns.
