The rise in carbapenemases-producing organisms has challenged the scientific community. Infections caused by these bacteria have limited treatment options. There are various types such as carbapenemase (Ambler class A), metallo-beta-lactamases of VIM-type, IMP-type, NDM-type (Ambler class B), and OXA-48-types (Ambler class D). An efficient strategy for detection of carbapenemase producers is important to determine the appropriate therapeutic modalities. In this study, four methods - Carba NP test, modified Carba NP (MCNP) test, carbapenem inactivation method (CIM) test, and Rapidec Carba NP kit test were evaluated. We evaluated an in-house MCNP test to detect carbapenemase production using a single protocol which gave reliable results. Furthermore, CIM using routine antibiotic discs gives good results. Both these tests were found to be cost-effective.

Unlabelled: Medical students report higher stress and increased mental illness than peers of similar age. Burnout and depression among medical students and physicians have also been correlated with increased risk of medical errors and decreased importance of altruistic values, such as providing care to medically underserved populations. This study works to analyze the effects of exercise, nutrition, sleep, and other factors affecting wellness and performance of medical students, as well as identifying barriers to exercise and possible solutions.

Integrons mediate the acquisition and expression of gene cassettes (GCs). The production of beta-lactamases (BLs) is the most relevant mechanism of beta-lactams resistance. To explore the role of integrons in BL genes dissemination, we retrieved sequences and metadata from the INTEGRALL database and performed literature review.

Article Synopsis
- Pseudomonas aeruginosa is highly resistant to antibiotics due to intrinsic and acquired mechanisms, primarily utilizing Pseudomonas-derived cephalosporinase (PDC) and serine Ambler class C β-lactamases through the AmpC gene system.
- * A study analyzed 111 P. aeruginosa isolates from India, identifying the ESAC allele PDC-447 as the most prevalent variant, particularly among carbapenem-resistant strains, while also noting other significant variants like PDC-398 and PDC-397.
- * Genetic mutations in the PDC enzyme, such as T105A in the H-helix region, were linked to increased antibiotic resistance, emphasizing the complexity of resistance mechanisms and
Modified Carba PBP test for rapid detection and differentiation between different classes of carbapenemases in Enterobacterales.

An advanced biochemical assay named modified Carba PBP test was innovated to identify and differentiate distinct categories of clinically significant carbapenemases (Ambler classes A, B, and D) within the Enterobacterales. The mechanism of mCarba PBP hinges on two core attributes: (i) the hydrolysis of the meropenem substrate by various carbapenemases, (ii) the immobilized penicillin and free meropenem in their affinity to interact with a limited quantity of penicillin-binding protein (PBP). Specific inhibitors for class A (phenylboronic acid, PBA) and class B (ethylenediaminetetraacetic acid, EDTA) were employed to inhibit the hydrolysis activity of carbapenemase and facilitate the classification of carbapenemase classes within 25 min.

Infections caused by carbapenem-resistant Enterobacterales (CRE) are progressively increasing in Pediatric Intensive Care Units (PICUs). Its treatment is challenging due to the lack of pediatric trials. CRE infections are associated with significantly poor outcomes, but ceftazidime-avibactam (CAZ-AVI) has been reported to be successful in their treatment.
