Scrub typhus is one of the common causes for acute febrile illness in monsoon and post-monsoon season in our region. It usually presents as fever, rash, and thrombocytopenia with or without multiorgan dysfunction syndrome (MODS). Infrequently, it can cause focal or symmetrical peripheral gangrene (SPG).

Background: Infection prevention and control (IPC) practices by critical care nurses are crucial in preventing ventilator-associated pneumonia (VAP) and central-line-associated bloodstream infection (CLABSI).

Aim: To implement an integrative approach to developing a set of IPC practices and disseminating information on the IPC practices through an educational multimedia tool to improve compliance with the practices.

Methods: This participatory interventional before-after study was conducted in a single tertiary care centre's cardiac surgical intensive care unit (ICU) from May 2022 to March 2023.

Background: Development of ventilator-associated pneumonia (VAP) is attributed to the microaspiration of pooled secretions around the cuff of airway devices. Despite the emphasis on the use of endotracheal tubes (ET) with subglottic secretion (SS) drainage ports to prevent VAP, the quality of the evidence for this recommendation remains moderate. This prospective observational study analyzed microbiological concordance between SS and endotracheal aspirate (ETA) cultures to generate further evidence in this regard.

Cefepime-tazobactam (FEP-TAZ) consists of cefepime combined with tazobactam, a penicillanic acid-sulfone recognized as an established beta-lactamase inhibitor. This study aims to investigate the in-vitro effectiveness of FEP-TAZ against cefepime-resistant clinical isolates of Escherichia coli (E. coli).

Article Synopsis
  • Urban rodents at Kolkata's Alipore Railway Station were studied for their role in spreading zoonotic pathogens, particularly Bartonella spp., through fleas, highlighting the link between high rodent populations and increased disease risk due to nearby human activity.
  • The study involved collecting and identifying rodents and fleas, as well as detecting Bartonella DNA to understand its prevalence and phylogenetic relationships among different species.
  • Results showed a high prevalence of Bartonella infections in rodents (53.33%) and fleas (79.1%), with some haplotypes indicating cross-species transmission between rodents, fleas, and humans, underscoring the public health implications of these findings.

Background: An eschar is not always present in all scrub typhus patients. Furthermore, such patients may present to tertiary care hospitals after administration of doxycycline. The present study aimed to determine the usefulness of using the swab from eschar sites in the diagnosis of scrub typhus in patients who present post-doxycycline therapy.

Article Synopsis
  • - This study investigates the prevalence and prognosis of secondary hemophagocytic lymphohistiocytosis (sHLH) in adult scrub typhus patients in North India, finding it affects 18.7% of patients.
  • - Key diagnostic factors include high-grade fever, seizures, and elevated ferritin levels, with ferritin showing the strongest correlation (AUC 0.83) for diagnosing sHLH.
  • - The research highlights that patients with sHLH have a significantly higher in-hospital mortality rate (21.4%) compared to those without (6.6%), stressing the importance of early detection for better management.

Article Synopsis
  • The study investigates the prevalence and impact of candidaemia in 67 ICUs across India, assessing how the COVID-19 pandemic influenced its rates and mortality.* -
  • Data from 401,601 patient days revealed higher candidaemia rates in COVID-19 ICUs (2.52/1000 patient days) compared to non-COVID-19 ICUs (1.05/1000 patient days), with associated mortality significantly higher in COVID-19 cases (61% vs. 41%).* -
  • Analysis identified C. tropicalis as the most common isolated species (26.7%), while C. auris, which had a high mortality rate, accounted for 17.5% of isolates

Background: Ventilator-associated pneumonia (VAP) is a major cause of morbidity and mortality in patients receiving mechanical ventilation in India. Surveillance of VAP is essential to implement data-based preventive measures. Implementation of ventilator-associated events (VAE) criteria for surveillance has major constraints for low resource settings, which can lead to significant underreporting.

Scrub typhus infection is reemerging leading cause of acute febrile illnesses in post-rainy or monsoon season in Southeast Asia. It is caused by Orientia tsutsugamushi and spread by the bite of chiggers, larval forms of trombiculid mites. The clinical picture can range from simple acute febrile illness to multiorgan dysfunction.

Background: Detection of infectious diseases, especially among immunocompromised and patients on prolonged anti-microbial treatment, remains challenging, limited by conventional techniques with low sensitivity and long-turnaround time. Molecular detection by polymerase chain reaction (PCR) also has limited utility as it requires a targeted approach with prior suspicion of the infecting organism. Advancements in sequencing methodologies, specifically next-generation sequencing (NGS), have presented a promising opportunity to identify pathogens in cases where conventional techniques may be inadequate.

Scrub typhus is a zoonotic disease caused by Orientia tsutsugamushi. Although the presence of eschar is considered pathognomic, diagnosis of scrub typhus is challenging due to overlapping presentation. The diagnosis is based on the serological and molecular assay.

Introduction: Acute encephalitis syndrome (AES) or acute febrile encephalopathy is a clinical condition characterized by altered mental status occurring after or along with a short febrile illness. In developing countries, infections are the predominant cause of AES. Prominent infections known to cause AES include viruses (such as herpes simplex virus [HSV], Japanese Encephalitis [JE] virus, dengue, enteroviruses [EVs]), bacteria, fungus, and parasites.

Article Synopsis
  • * Researchers trapped rodents in Chandigarh and Punjab, screening them for ticks and rickettsial agents using specific PCR methods and sequencing to identify genetic relationships.
  • * The findings confirm the presence of Rickettsia rhipicephali in the community, a non-pathogenic rickettsial agent, and call for increased surveillance to assess the prevalence of rickettsial diseases in the region.

Background & Aims: The reported burden of multidrug-resistant organism (MDRO) infections is highest in patients with cirrhosis from India. We evaluated whether colonisation at multiple barriers predisposes to such infections and poor outcomes in patients with cirrhosis.

Methods: We prospectively performed swab cultures, antimicrobial susceptibility testing (AST), and genotype testing for MDROs from various sites (rectum, nose, composite-skin, and central-line) in patients with cirrhosis (2020-2021) on admission and follow-up at a tertiary institute.

Background: The maintenance bundle of care for all venous access devices (peripheral intravenous catheters, PIVC; central venous catheters, CVCs; hemodialysis ports) is important to prevent secondary sepsis in critically ill patients. This quality improvement project analyzed the effect of intensive training and education of health care workers (HCWs) on maintenance bundles for venous access devices.

Methods: The study period comprising of preintervention phase (3-months) included 25 random visits to the intensive care unit for point observations regarding maintenance of all venous access devices in-situ in all intensive care unit patients on the day of the visit.

The utility of surveillance stool culture (SSC) to guide antibiotics for febrile neutropenia (FN) is unresolved in non-transplant settings. The prospective study explored the prevalence of multidrug-resistant organisms (MDRO) in SSCs, its correlation with mortality, and the concordance of SSCs with cultures obtained during subsequent episodes of FN amongst children with acute leukemia. SSCs were obtained at presentation and 2 mo into chemotherapy.
