RESUMEN
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. Surveillance of VAP using common protocols in a large network of hospitals would give meaningful estimates of the burden of VAP in low resource settings. This study leverages a previously established healthcare-associated infections (HAI) surveillance network to develop and test a modified VAP definition adjusted for Indian settings. Methods: In this observational pilot study, thirteen hospitals from the existing HAI surveillance network were selected for developing and testing a modified VAP definition between February 2021 and April 2023. The criteria used for diagnosing VAP were adapted from the CDC's Pediatric VAP definition and modified to cater to the needs of Indian hospitals. Designated nurses recorded each VAP event in a case report form (CRF) and also collected denominator data. The data was entered into an indigenously developed database for validation and analysis. At the time of data analysis, a questionnaire was sent to sites to get feedback on the performance of the modified VAP definitions. Findings: Out of 133,445 patient days and 40,533 ventilator days, 261 VAP events were recorded, with an overall VAP rate of 6.4 per 1000 ventilator days and a device utilization ratio (DUR) of 0.3. A total of 344 organisms were reported from the VAP events. Of these, Acinetobacter spp (29.6%, 102) was the most frequent, followed by Klebsiella spp (26.7%, 92). Isolates of Acinetobacter spp (98%) and Enterobacterales (85.5%) showed very high resistance against Carbapenem. Colistin resistance was observed in 6% of Enterobacterales and 3.2% of Acinetobacter spp. Interpretation: Data from this pilot study needs to validated in the larger Indian HAI surveillance network so that it can help in wider implementation of this protocol in order to assess its applicability p VAP across India. Funding: This work was supported by a grant received from the Indian Council of Medical Research (code I-1203).
RESUMEN
The availability of syndrome-based panels for various ailments has widened the scope of diagnostics in many clinical settings. These panels can detect a multitude of pathogens responsible for a particular condition, which can lead to a timely diagnosis and better treatment outcomes. In contrast to traditional identification methods based on pathogen growth on culture, syndrome-based panels offer a quicker diagnosis, which can be especially beneficial in situations requiring urgent care, such as intensive care units. One such panel is the Biofire Filmarray Pneumonia plus Panel (BFP), which we have compared against microbiological culture and identification. The lower respiratory samples from patients were tested with BFP, culture, and identification with culture considered the gold standard. The phenotypic antibiotic susceptibility results (Vitek 2) were compared with the antimicrobial resistance (AMR) genes detected in BFP. Statistical analysis was carried out using GraphPad 7.0 and MS Excel (Microsoft Inc.). The results showed a positive percent agreement of 100% and a negative percent agreement of 47.8% with an overall agreement of 76.72% compared to culture. BFP was better at identifying fastidious bacteria, and the agreement with culture was higher for high bacterial identification numbers (107 and 106). There was also a correlation between the number of pathogens detected and growth in culture. Carbapenemase genes were detected in around 80% of phenotypically resistant samples and correlated with in-house PCR 60% of the time. Hence, BFP results need to be interpreted with caution especially when multiple pathogens are detected. Similarly, the presence or absence of AMR genes should be used to guide the therapy while being watchful of unusual resistance or susceptibility. The cost constraints and low throughput call for patient selection criteria and prioritization in emergency or resource-limited conditions.IMPORTANCEApplication of syndrome-based panels in clinical microbiology is of huge support in infectious conditions requiring urgent interventions, such as pneumonia. Interpreting the results requires caution; hence, we have compared the results obtained from Biofire Filmarray Pneumonia plus Panel with standard microbiological methods.

INTRODUCTION: Kodamaea ohmeri is a rare, recognized pathogen that has previously been isolated from environmental sources. The patients commonly affected by this yeast include immunocompromised as well as immunocompetent patients having several associated risk factors. METHODOLOGY: We report three cases in which K. ohmeri was isolated from blood using Bact T/ALERT. Identification was carried out by MALDI-TOF MS (Vitek-MS, BioMérieux, Marcy-l'Etoile, France) in addition to color characteristics on chromogenic media. The patients had diminished immune response on account of a multitude of comorbidities. RESULTS: K. ohmeri can be misidentified as Candida tropicalis, Candida albicans, or Candida hemolounii by conventional methods; correct and timely identification can be achieved by MALDI-TOF MS. Antifungal susceptibility breakpoints for K. ohmeri are currently not defined. An Echinocandin was added to the treatment regimen of all three of the cases. CONCLUSIONS: Identification of K. ohmeri using conventional methods is difficult and unusual yeasts should be carefully observed, especially upon prolonged incubation.

INTRODUCTION: Invasive mould infections (IMIs) are a leading cause of death in patients with compromised immune systems. Proven invasive mould infection requires detection of a fungus by histopathological analysis of a biopsied specimen, sterile culture, or fungal DNA amplification by PCR in tissue. However, the clinical performance of a PCR assay on blood samples taken from patients suspected of invasive mould disease has not been fully evaluated, particularly for the differential diagnosis of invasive aspergillosis (IA) and invasive Mucormycosis (IM). OBJECTIVES: To assess the diagnostic utility of our previously validated in-house real-time PCR in blood samples for diagnosis of invasive aspergillosis and mucormycosis in patients with suspected invasive mould infection. METHODS: All patients with suspected invasive mould infection were prospectively enrolled from May 2021 to July 2021. Conventional fungal diagnosis was performed using tissue and respiratory samples. In-house PCR was performed on blood samples and its diagnostic performance evaluated. RESULTS: A total of 158 cases of suspected invasive mould infection were enrolled in the study. The sensitivity and specificity of in-house PCR performed on blood samples was found to be 92.5% and 81.4% respectively for diagnosis of probable IA, and 65% and 84.62% respectively for diagnosis of proven and probable IM. It was also able to detect 3 out of 5 cases of possible IM where no other microbiological evidence of IM was obtained. CONCLUSIONS: This assay could be helpful in minimally invasive diagnosis of IMIs for patients in whom invasive sampling is not feasible, especially as a preliminary or screening test. It can help in early diagnosis, anticipating conventional laboratory confirmation by days or weeks. Possible correlation between fungal load and mortality can help in initiating aggressive treatment for patients with high initial fungal load.

Background: Secondary bacterial infections during COVID-19 hospitalization have been reported in about 6-15% of patients. Aims: To study the secondary bacterial infections that affected the COVID-19 patients during their hospitalisation and to unearth the bacteriological profile of samples obtained after their demise. Settings and Design: This prospective study was carried out at a COVID-19 dedicated, apex tertiary care centre in North India from July 2020 to April 2021. Methods and Materials: Samples of 268 patients were considered for the study. Nasopharyngeal swab specimen, blood, and tissue (lung) were collected from the deceased body as early as possible and processed. Statistical Analysis: Statistical analyses were performed using STATA version 11.1 (Stata Corp., College Station, TX, USA). Results: A total of 170 samples were received from patients before their death, which included blood, urine, respiratory samples, pus, and cerebrospinal fluid. Forty-four pathogens were isolated, which consisted of Acinetobacter baumannii (43.1%), Klebsiella pneumoniae (36.3%), Escherichia coli (11.3%), and Pseudomonas aeruginosa (4.5%), Enterococcus faecium (4.5%). Two hundred fifty-eight samples were collected from the deceased bodies wherein the nasopharyngeal sample was highest, followed by tissue and blood. A total of 43 pathogens were isolated among them which included A. baumannii (44.1%), followed by K. pneumoniae (25.5%), E. coli (20.9%), P. aeruginosa (6.97%) and Enterobacter cloacae (2.3%). All these isolates were highly resistant to antimicrobials. Conclusions: In our study, bacterial profiles in antemortem and postmortem samples were found to be similar, suggesting that resistant pathogens may be the cause of mortality in COVID-19 infected hospitalised patients.

INTRODUCTION: Candida auris is a notorious pathogen capable of forming biofilms on devices as well as host tissues, often culminating in infections. We evaluated characteristics of infections and the methods to diagnose C. auris over a period of three years in a tertiary care hospital. METHODS: Patients admitted between 2018 and 2020, who had candidemia due to C. auris were included in the study. Identification was performed using HiCrome™ Candida Differential Agar, Vitek 2 (BioMérieux, Inc., Marcy-l'Etoile, France) and MALDI-TOF, Vitek-MS. Identification was confirmed by detection of rDNA region covering part of 5.8S, entire of ITS2, and part of 28S by polymerase chain reaction (PCR). Biofilm formation was assessed by crystal violet staining. RESULTS: Presence of central line and broad spectrum antimicrobials were noted in all patients whereas total parenteral nutrition was given in 82.1% of these patients. Identification by Vitek2 v8.1 correlated with MALDI-TOF MS. PCR products of length 163 âbp were obtained in all isolates as visualized by agarose gel electrophoresis. The biofilm quantity measured as A560 of the twenty-eight C. auris isolates ranged from 0.16 to 0.80 compared to C. albicans. CONCLUSIONS: C. auris can be identified by PCR targeting specific rDNA region. Biofilm formation and quantification can be achieved by growing C. auris isolates in Mueller-Hinton broth over a duration of 48 âh.

BACKGROUND: This study was conducted to understand the effect of the COVID-19 pandemic on urine culture and sensitivity results in an outpatient setting. There are plenty of data from inpatient and ICU settings but there is a paucity of data in outpatient or community settings. Thus, this study primarily targeted change in antibiotic resistance of urinary tract infection (UTI) agents in the pre- and post-COVID-19 period. METHODS: In the study, urine samples received in the Department of Laboratory Medicine (microbiology laboratory) with a preliminary diagnosis of UTI between April 2019 and March 2021 were analyzed. Urine cultures and antibiotic susceptibility tests of the patients included in the study were examined in two periods (pre-pandemic and post-pandemic). RESULTS: A total of 22,372 urine samples were received in the pre-pandemic period (April 2019 to March 2020) and 4885 samples in the post-pandemic period (April 2020 to March 2021). The positivity rate obtained from urine cultures sent post-COVID-19 pandemic (16%) was significantly higher than those sent before the COVID-19 pandemic (8%). According to cultures and antibiogram results, resistance to ampicillin, amikacin, ceftazidime (p < 0.05), co-trimoxazole, levofloxacin, gentamicin (p < 0.05), nitrofurantoin, fosfomycin, and tetracycline decreased compared with the pre-COVID-19 period. CONCLUSIONS: In this study, we found that the frequency of significant bacteriuria increased significantly in the post-pandemic period. However, resistance to antibiotics decreased significantly in the post-COVID-19 period compared to the pre-COVID-19 period. There was no significant change in the etiology of UTI during the two time periods.
RESUMEN
Introduction Intestinal parasitic infections continue to loom in developing countries with low sanitation and socioeconomic conditions. Pandemic times are especially important to study the prevalence of these pathogens since the focus of all healthcare services was coronavirus disease 2019 (COVID-19). This study aimed to evaluate the prevalence and time-trend of intestinal parasitic infections in the capital region of India during the pandemic times. Methods In this cross-sectional study, a retrospective review based on data from the past 2 years in the post-COVID-19 pandemic was used. Descriptive and time-trend analyses were applied to the data. Time series analysis was analyzed using the best fit autoregressive integrated moving average (ARIMA) model to look for seasonality in trends and forecasting. Results A total of 7267 patients' stool samples over a 2-year pandemic period were included in the study. Intestinal parasites were detected in 11.18% (813/7276) patients. Giardia lamblia (2.28%) and Blastocystis hominis (3.78%) were the predominant ones. Time-trend analysis from 2020 to 2021 using ARIMA model predicted an increasing trend with waning of pandemic. The most prevalent infection was found in the monsoon and autumn months. Conclusion Rates of infection with Giardia lamblia and Blastocystis hominis have increased in comparison to other protozoan infections like Entamoeba histolytica when compared with prepandemic hospital-based studies. With fading of the pandemic, further increasing trends are predicted.
RESUMEN
Aim: The increasing burden of resistance in Gram-negative bacteria (GNB) is becoming a major issue for hospital-acquired infections. Therefore, understanding the molecular mechanisms is important. Methodology: Resistance genes of phenotypically colistin-resistant GNB (n = 60) were determined using whole genome sequencing. Antimicrobial susceptibility patterns were detected by Vitek®2 & broth microdilution. Results: Of these phenotypically colistin-resistant isolates, 78% were also genetically resistant to colistin. Activation of efflux pumps, and point-mutations in pmrB, and MgrB genes conferred colistin resistance among GNB. Eight different strains of K. pneumoniae were identified and ST43 was the most prominent strain with capsular type-specific (cps) gene KL30. Discussion: These results, in combination with rapid diagnostic methods, will help us better advice appropriate antimicrobial regimens.
RESUMEN
Background Human microsporidiosis presents as an important and rapidly emerging opportunistic infection. However, the exact burden of this infection especially in the pediatric population of Northern India remains unknown. In this study, we investigated the prevalence of microsporidia among human immunodeficiency virus (HIV)-positive and HIV-negative pediatric patients who presented with diarrhea. Methods A total of 263 children were recruited consisting of 98 HIV seropositive with diarrhea and 165 HIV seronegative but with diarrhea. Morning stool samples were collected and both direct and formol ether concentrated samples were examined for the presence of intestinal parasites. The modified acid-fast staining was done for coccidian parasites and trichrome stain for microsporidia detection. Further, the species were detected using a real-time polymerase chain reaction (PCR) targeting a conserved region of the small ribosomal subunit rRNA gene of Enterocytozoon bieneusi , Encephalitozoon hellem , Encephalitozoon intestinalis , and Encephalitozoon cuniculi . Results Overall, one or more parasites were detected in 52.04% (51/98) of HIV seropositive and 53.33% (88/165) of seronegative children ( p = 0.8391). However, coccidian parasites were detected in a significantly huge number of HIV seropositive children (21.43% [21/98]) as compared with HIV seronegative children (4.24% [7/165]). Microsporidial DNA could be detected in HIV seropositive with diarrhea children (17.35% [17/98]) by PCR. A significant correlation between low CD4 count (≤ 200/µL) and intestinal parasite positivity could be established. Conclusion Microsporidia is a significant cause of diarrhea in HIV seropositive pediatric patients and should be kept in mind as one of the differential diagnoses in such patients.
RESUMEN
Background & objectives: High transmissibility of the SARS-CoV-2 has significant implications on healthcare workers' safety, preservation, handling, transportation and disposal of the deceased bodies. The objective of this study was to detect SARS-CoV-2 antigen in nasopharyngeal samples and its implications in handling and care of COVID-19 deceased bodies. Methods: A study was conducted at a dedicated COVID-19 centre on deceased individuals from April to December 2020. Rapid antigen test (RAT) and reverse transcription (RT)-PCR was compared on all the SARS-CoV-2 positive cadavers recruited in the study. Results: A total of 115 deceased individuals were included in the study. Of these, 79 (68.7%) were male and 36 (31.3%) were female and majority were in the age group of 51-60 yr [31 (27%)]. SARS-CoV-2 antigen test was positive in 32 (27.8%) and negative in 83 (72.1%) individuals. The mean time interval between deaths to the sample collection was 13.2 h with interquartile range of eight to 20 h. Reverse transcription (RT)-PCR was used as the reference test and 24 (20.9%) cases were true positive; 93.6 per cent [95% confidence interval (CI) 88.8-98.4%] sensitivity, 45.2 per cent (95% CI 35.5-55%) specificity, 60.2 per cent (95% CI 50.6-69.8%) positive predictive value and 88.8 per cent (95% CI 82.7-95%) negative predictive value of antigen test was computed. Interpretation & conclusions: SARS-CoV-2 antigen test was positive beyond 19 h in COVID-19 deceased individuals. Antigen test was found to be highly sensitive in the deceased. Patients, suspected of having died due to COVID-19, can be screened by this method. As infectiousness of the virus in the deceased bodies cannot be directly concluded from either the antigen or RT-PCR test, yet possible transmission cannot be completely ruled out. Strict infection control measures need to be followed during the handling and clearance of COVID-19 cadavers.

Introduction. Invasive mucormycosis (IM) is a potentially fatal infection caused by fungi of the order Mucorales. Histopathology, culture, and radiology are the mainstays of diagnosis, but they are not sufficiently sensitive, resulting in delayed diagnosis and intervention. Recent studies have shown that PCR-based techniques can be a promising way to diagnose IM.Hypothesis/Gap Statement. Early diagnosis of fungal infections using molecular diagnostic techniques can improve patient outcomes, especially in invasive mucormycosis.Aim. The aim of this study was to evaluate the utility of our in-house mould-specific real time PCR assay (qPCR) in comparison with the commercially available real time PCR (MucorGenius PCR), for the early diagnosis of mucormycosis in tissue samples from patients with suspicion of invasive mucormycosis (IM). This in-house assay can detect and distinguish three clinically relevant mould species, e.g. Aspergillus spp., Mucorales and Fusarium spp. in a single reaction with only one pair of primers, without the need for sequencing.Methodology. We enrolled 313 tissue samples from 193 patients with suspected IM in this prospective study. All cases were classified using EORTC/MSGERC guidelines. All samples were tested using traditional methods, in-house qPCR, and MucorGenius PCR.Results. Using direct microscopy as a gold standard, the overall sensitivity and specificity of in-house qPCR for detection of IM was 92.46% and 80% respectively, while that of the MucorGenius PCR was 66.67% and 90% respectively. However, co-infection of IM and IA adversely affected the performance of MucorGenius PCR in detection of IM.The in-house PCR detected Aspergillus spp. in 14 cases and Fusarium spp. in 4 cases which showed clinical and radiological features of fungal sinusitis. The in-house qPCR also performed better in detecting possible cases of IM. This aids early diagnosis and appropriate treatment to improve patient outcomes.Conclusion. Because the in-house PCR is not only sensitive and specific, but also entirely based on SYBR Green for detection of targets, it is less expensive than probe-based assays and can be used on a regular basis for the diagnosis of IM in resource-constrained settings. It can be used to distinguish between mucormycosis and fungal sinusitis caused by Aspergillus and Fusarium in high-risk patients, as well as to accurately detect Mucorales in fungal co-infection cases.

BACKGROUND: As there is a lack of comprehensive literature regarding the molecular environment of the human brain emphasizing on oligodendrocyte progenitor cells (OPCs) following high impact brain trauma. The protagonist of OPCs post severe traumatic brain injury (sTBI) provides a significant thrust towards estimating time elapsed since trauma as well as developing novel therapeutic approaches. The present study was carried out to study post trauma alterations pertaining to myelin sheath and oligodendrocyte response with survival time. MATERIALS AND METHODS: In the present study, victims (both male and female) of sTBI (n = 64) were recruited and contrasted with age and gender matched controls (n = 12). Post mortem brain samples from corpus callosum and grey white matter interface were collected during autopsy examination. Extent of myelin degradation and response of OPC markers Olig-2 and PDGFR-α were evaluated using immunohistochemistry and qRT-PCR. STATA 14.0 statistical software was used for data analysis with P-value<0.05 considered statistically significant. RESULTS: Timewise qualitative correlation with extent of demyelination performed using LFB-PAS/IHC-MBP, IHC Olig-2 and mRNA expression revealed tendency towards remyelination in both corpus callosum and grey white matter interface. Number of Olig-2 positive cells was significantly higher in sTBI group as compared to control group (P-value: 0.0001). Moreover, mRNA expression studies of Olig-2 showed significant upregulation in sTBI patients. mRNA expression of Olig-2 and PDGFR-α in sTBI patients showed significant variation with respect to survival time (p value:0.0001). CONCLUSION: Detailed assessment of post TBI changes implementing various immunohistochemical and molecular techniques shall potentially reveal intriguing and important inferences in medicolegal practices and neurotherapeutics.

BACKGROUND: Hand hygiene is the single most effective strategy for preventing healthcare associated infections (HCAI) but compliance is usually low and effective improvement strategies are needed. We assessed hand hygiene (HH) compliance with the World Health Organization (WHO) prescribed five moments of hand hygiene among health-care workers (HCW). METHODS: A retrospective analysis of one-year data on hand hygiene was done. WHO single observer direct observation technique was used and HH compliance was noted among HCWS. RESULTS: A total of 16,552 opportunities were recorded. Overall compliance as per WHO Guidelines was 69.2%. Sanitation worker had an adherence rate of 73.1% (95% confidence interval [CI]:70.6-75.4) followed by the nurses 71.2% (95% CI: 70.4-72.1). Physicians and technicians had a compliance rate of 64.9% (95% CI: 63.1-66.6) and 64% (95% CI: 60.1-67.9) respectively. Physiotherapists had a compliance rate of 62.2 (95% CI: 50.1-73.2) and the compliance of Phlebotomists was observed to be 23.1% (95% CI: 9.0-43.6). HCW stood best for WHO moment 5 and worst for moment 1 with compliance of 79.1% (95% CI:77.4-80.7) and 55.8% (95% CI:54.5-57.1) respectively. DISCUSSION: The moment 1 of the WHO's five moments is the most important for preventing the transmission of resistant pathogens between patients. Missed opportunities in moment 1 need to be focused on while planning new strategies to promote hand hygiene.

PURPOSE: Healthcare-associated infections (HAIs) are a leading cause of morbidity and mortality in low- and middle-income countries (LMICs). Moreover, the burden of HAIs is higher in ICU admitted patients. Long term studies are beneficial to evolution pattern of AMR. Therefore, this study aimed to evaluate the evolution of AMR pattern over the years in one of the ICUs of a level 1 Trauma Center. This will enable us to modify the prescribing practices according to emerging resistance patterns. METHODS: This study was conducted at one of the ICU of level-1 trauma center of tertiary care hospital. The study reports the findings of the AMR surveillance from January 2012 to December 2019. Standard definitions were used to define HAI (www.hais.com). The clinical records of the patients were maintained using ASHAIN indigenous software. Outbreak analysis was done by WHONET. RESULTS: From 1st January 2012-31st December 2019, 4305 isolates were obtained from 1969 patients. Most frequent occurring organism were gram negatives among which A. baumannii was common followed by K. pneumoniae, and P. aeruginosa. Retrospective analysis showed 7 outbreaks/clusters during the study period and all the outbreaks occurred from October to December in each year. The increasing trend of AMR pattern emphasizes to strengthen infection control practices and sustained AMR surveillance.

Background: There are studies available on the prevalence of coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) in hospitalized patients but not on the incidence of CAM in post-discharge patients. The aim of our study was to find the incidence of CAM in the patients discharged from a COVID hospital. Material and Methods: Adult patients with COVID discharged between March 1, 2021 and June 30, 2021 were contacted and enquired about sign and symptoms of CAM. Data of all included patients were collected from electronic records. Results: A total of 850 patients responded, among which 59.4% were males, 66.4% patients had co-morbidities, and 24.2% had diabetes mellitus. Around 73% of patients had moderate to severe disease and were given steroids; however, only two patients developed CAM post discharge. Conclusion: The incidence of CAM post discharge was low in our study, which could be attributed to protocolized therapy and intensive monitoring.
RESUMEN
COVID-19 demanded urgent and immediate global attention, during which other public health crises such as antimicrobial resistance (AMR) increased silently, undermining patient safety and the life-saving ability of several antimicrobials. In 2019, WHO declared AMR a top ten global public health threat facing humanity, with misuse and overuse of antimicrobials as the main drivers in the development of antimicrobial-resistant pathogens. AMR is steadily on the rise, especially in low-income and middle-income countries across south Asia, South America, and Africa. Extraordinary circumstances often demand an extraordinary response as did the COVID-19 pandemic, underscoring the fragility of health systems across the world and forcing governments and global agencies to think creatively. The key strategies that helped to contain the increasing SARS-CoV-2 infections included a focus on centralised governance with localised implementation, evidence-based risk communication and community engagement, use of technological methods for tracking and accountability, extensive expansion of access to diagnostics, and a global adult vaccination programme. The extensive and indiscriminate use of antimicrobials to treat patients, particularly in the early phase of the pandemic, have adversely affected AMR stewardship practices. However, there were important lessons learnt during the pandemic, which can be leveraged to strengthen surveillance and stewardship, and revitalise efforts to address the AMR crisis.
