Background: Blood cultures are the most significant samples received in a microbiology laboratory. Good quality control of pre-analytic, analytic, and post-analytic stages can have a significant impact on patient outcomes. Here, we present the improvements brought about by reviewing blood culture data with clinicians at a tertiary care institute in India.
Methods: Four-year blood culture data (phase I-February 2014-February 2018) were shared with clinicians in the clinical grand round. Several take-home messages were discussed in a quiz format, and a number of holistic quality control measures were implemented at different levels. Based on observable changes in blood culture reports, another dataset was analyzed and compared in phase II (April 2018-April 2019).
Results: In phase II, the blood culture contamination rate improved from 6 to 2% along with four times reduction in ICU isolates and three times increased isolation of salmonellae and pneumococci. The development of resistance in to carbapenems and piperacillin-tazobactam was reduced. Colistin resistance in ICU isolates hovered around 15%. Vaccine-preventable pneumococcal serotypes were predominant in the under-five age-group. Typhoidal salmonellae were more commonly isolated from adults with 50% showing sensitivity to pefloxacin and 97% to ampicillin, chloramphenicol, and cotrimoxazole. was the leading non- (NAC). Fluconazole resistance was observed in 50% of NAC.
Conclusion: Reviewing blood culture data with clinicians mutually helped us to improve the overall quality of blood culture reports. It had a major impact on epidemiological trends and thus, found to be superior to just sharing an antibiogram with the clinicians.

Background: Culture medium enriched with Knockout serum replacement (KSR) can produce in vitro mouse sperm, but it is inefficient, strain-specific and contains bovine products, which limits its use in the human clinic. The study aimed to optimize the culture medium for testicular tissue by using plasma rich in growth factors (PRGF) as a serum supplement, addressing the limitations of KSR.
Methods: Immature testicular tissues from NMRI mice were cultured for 14 days to identify the optimal PRGF concentration using histological analysis and tubular integrity scoring.

Background: Cardiovascular disease (CVD), a non-communicable condition, stands as the primary cause of death globally. This study seeks to evaluate the predictive power of atherogenic indices, which are recognized for their influence on CVD, alongside a newly developed index encompassing all three principal risk factors for CVD, referred to as the triglyceride-total cholesterol-body weight index (TCBI). The primary outcomes evaluated include both the incidence and mortality rates associated with CVD.

Paediatric blood cultures are vital for the diagnosis of paediatric bloodstream infections. Quality of paediatric blood culture collection, processing and reporting depend on multiple factors, with a paucity of literature describing these in practice. We conducted separate surveys of clinicians and laboratory staff to assess quality standards and knowledge related to paediatric blood culture collection, analysis, and interpretation to identify improvement opportunities.

Background: The recovery of injured peripheral nerves relies on angiogenesis, where newly formed blood vessels act as pathways guiding Schwann cells across the wound to support axon regeneration. While some research has examined this process, the specific mechanisms of angiogenesis in peripheral nerve healing remain unclear. In vitro models are vital tools to investigate these mechanisms; however, no current in vitro culture methods exist for isolating vascular cells, such as endothelial cells (ECs) and pericytes, specifically from sciatic nerves.

Current research on common parasitic nematodes is limited because their infective stages cannot be propagated in vitro. Here, we report a culture system for developing L4s of Haemonchus contortus, a blood-feeding nematode of ruminants. Our results demonstrated that a proportionate mixture of NCTC-109 to Luria-Bertini (1:2) media promoted the formation of early L4s and then into late L4s upon inclusion of 12.
