Supporting people in Early Intervention in Psychosis services: the role of primary care.

BACKGROUND: Early Intervention in Psychosis (EIP) services offer treatment to people experiencing a first episode of psychosis. Service users may be referred from primary care and discharged directly back at the end of their time in an EIP service. AIM: To explore the role of primary care in supporting EIP service users (SUs) and to understand how to improve collaboration between primary and specialist care. METHOD: Qualitative study comprising semi-structured interviews with SUs, carers, healthcare professionals (HCPs), managers, and commissioners. Interviews were conducted either online or by telephone. Thematic analysis was carried out using principles of constant comparison. Patient and public involvement were key to all stages, including data analysis. RESULTS: In total, 55 interviews were conducted with SUs (n = 13), carers (n = 10), and GPs, EIP HCPs, managers, and commissioners (n = 33). GPs reported difficulties in referring people into EIP services and little contact with SUs while in EIP services, even about physical health. GPs suggested they were not included in planning discharge from EIP to primary care. SUs and carers reported that transition from EIP can lead to uncertainty, distress, and exacerbation of symptoms. GPs reported only being made aware of patients on or after discharge, with no contact for 3 years. GPs described difficulty managing complex medication regimes, and barriers to re-referral to mental health services. CONCLUSION: GPs have a key role in supporting people within EIP services, specifically monitoring and managing physical health. Inclusion of GPs in planning discharge from EIP services is vital.

Current trends in antimicrobial resistance of ESKAPEEc pathogens from bloodstream infections - Experience of a tertiary care centre in North India.

INTRODUCTION: Bloodstream infections (BSI) due to ESKAPEEc pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanni, Pseudomonas aeruginosa, Enterobacter spp. and Escherichia coli), cause significant mobility and mortality worldwide and are among the most common healthcare associated infections. Rising rates of antimicrobial resistance (AMR) in India are alarming, because of the high infection rates and poor control of antibiotic use. This single-centre, retrospective study was undertaken to identify the patterns of distribution and antimicrobial resistance of ESKAPEEc pathogens in bloodstream infections. METHODOLOGY: Blood samples from patients with suspected BSI were cultured and antimicrobial susceptibility testing was performed on automated systems (BD Bactec Fx/BactAlert 3D and Vitek2). The microbiological data on bacterial BSI was retrieved from the laboratory records and antimicrobial resistance profiles were analysed. RESULTS: 10.7% of the blood culture samples showed bacterial growth during the study period (adult > paediatric and intensive care unit (ICU) > ward > outpatient department (OPD)). E. coli (24%) and K. pneumoniae (20.5%) were the predominant species isolated, followed by S. aureus (9.5%) and A. baumanni (9%). High rates of resistance to third generation cephalosporins, ß-lactam-ß-lactamase inhibitor combinations (BL-BLI) and carbapenems was observed, in Gram-negative isolates, especially from ICU patients. Methicillin-resistant S. aureus (MRSA) isolates increased from 67% to 88% over the five-year period. Vancomycin-resistance among Enterococcus isolates also escalated to 40% in 2022 with 11% linezolid resistance. CONCLUSION: The study revealed that more than 77% of bloodstream infections were caused by ESKAPEEc pathogens, with high rates of resistance to most antimicrobials. This reinforces the importance of monitoring the frequency of bacteria and antibiograms in individual treatment and hospital infection control programs.

Identifying the priorities for supervision by lived experience researchers: a Q sort study.

BACKGROUND: Lived experience researchers draw on their lived and living experiences to either lead on or inform research. Their personal experiences are relevant to the research topic and so they must manage the interplay of their health and healthcare experiences with the research, population, and data they work with, as well as the more general challenges of being a researcher. Lived experience researchers must navigate these dilemmas in addition to queries over their competency, due to issues relating to intersectionality and epistemic injustice. This justifies a motivation to better understand the experiences of lived experience researchers and develop appropriate and personalised supervision based on their preferences and needs. METHODS: Q methodology was used to identify a collection of identity-related issues that impact lived experience researchers during PhD research in the context of the UK. These issues were presented in the form of 54 statements to 18 lived experience researchers to prioritise as topics to explore in supervision. RESULT: It was found that lived experiences researchers could be grouped into three distinct factors following an inverted factor analysis: Factor 1: Strengthening my identity, skills, growth, and empowerment; Factor 2: Exploring the emotional and relational link I have with the research and Factor 3: Navigating my lived and professional experiences practically and emotionally. The findings suggest that there may be three types of lived experience researchers, each with different needs from supervision, suggesting the population is heterogeneous. CONCLUSION: The research identified a deeper understanding of the needs of lived experience researchers and highlights the importance of personalised supervision according to the individual needs of the researcher and their preferences for supervision. The findings reinforce the importance of integrating a clinical dimension into supervision to support the needs of all lived experience researchers.

Collaboration across the primary/specialist interface in early intervention in psychosis services: a qualitative study.

Background People with new psychotic symptoms may be managed within an Early Intervention in Psychosis service (EIP). They may be discharged back to primary care at the end of their time in an EIP service. Aim To explore the role of primary care in supporting people with psychosis in an EIP service. Design and Setting Qualitative study, within a programme of work to explore the optimum duration of management within an EIP service. Methods Semi-structured interviews with people in EIP services, carers, general practitioners (GPs) and EIP practitioners. Findings GPs report difficulties in referring people into EIP services, have little contact with people who are supported by EIP services and are not included in planning discharge from EIP service to primary care. Conclusions This study suggests that GPs should have a role in the support of people within EIP services (in particular monitoring and managing physical health) and their carers. Inclusion of GPs in managing discharge from EIP services is vital. We suggest that a joint consultation with the service user, their carer (if they wish) along with EIP care co-ordinator and GP would make this transition smoother.

Predictors of positive outcomes from 'Early Intervention in Psychosis': protocol for a national retrospective cohort study.

Background: Psychotic disorders are severe and prevalent mental health conditions associated with long-term disability, reduced quality of life, and substantial economic costs. Early Intervention in Psychosis (EIP) services aim to provide timely and comprehensive treatment for psychotic disorders, and EIP service input is associated with improved outcomes. However, there is limited understanding of the specific components of EIP care that contribute to these improvements. There is significant nationwide variability in the commissioning and delivery of EIP, with individuals receiving different packages of components from different services. In this study, we seek to explore associations between EIP components and clinically significant outcomes, in order to understand the mechanisms underlying improved psychosis care. Methods: This national retrospective cohort study will utilize data from the 2019 National Clinical Audit of Psychosis (NCAP), examining the care received by 10,560 individuals treated by EIP services in England. Exposure data from the NCAP, capturing the components of care delivered by EIP services, will be linked with outcome data from routine NHS Digital datasets over a three-year follow-up period. This will be the first study to use this method to examine this population in England. The primary outcomes will be surrogate measures of relapse of psychosis (hospital admission and referral to community-based crisis intervention services). Secondary outcomes include duration of admissions, emergency hospital attendances, episodes of detention under the Mental Health Act, and all-cause mortality. We will use multilevel regression to examine associations between exposures and outcome events. We will handle missing data using appropriate imputation techniques. Discussion: This study aims to provide valuable insights into the long-term effects of variations in EIP service delivery. The study involves a large, diverse cohort including individuals treated by every EIP service in England. While there are limitations inherent in the observational nature of the study, any associations identified will be of great relevance to clinicians, researchers, and policymakers seeking to optimize EIP care. The results will enable more targeted treatment planning, resource allocation, and potential innovations in EIP care, ultimately leading to improved prognoses for people experiencing psychosis.

Predictors of positive patient-reported outcomes from 'Early Intervention in Psychosis': a national cross-sectional study.

BACKGROUND: The components of care delivered by Early Intervention in Psychosis (EIP) services vary, but the impact on patient experience is unknown. OBJECTIVE: To investigate associations between components of care provided by EIP services in England and patient-reported outcomes. METHODS: 2374 patients from EIP services in England were surveyed during the National Clinical Audit of Psychosis. Participants were asked about the care they received, and completed the 'Patient Global Impressions' Scale (rating whether their mental health had improved), and 'Friends and Family Test' (rating whether they would recommend their service). Information about service structure was obtained from service providers. We analysed associations between outcomes and components of care using multilevel regression. FINDINGS: The majority of participants were likely to recommend the treatment they had received (89.8%), and felt that their mental health had improved (89.0%). Participants from services where care coordinators had larger case loads were less likely to recommend their care. Participants were more likely to recommend their care if they had been offered cognitive behavioural therapy for psychosis, family therapy or targeted interventions for carers. Participants were more likely to report that their mental health had improved if they had been offered cognitive behavioural therapy for psychosis or targeted interventions for carers. CONCLUSIONS: Specific components of EIP care were associated with improved patient reported outcomes. Psychosocial interventions and carer support may be particularly important in optimising outcomes for patients. CLINICAL IMPLICATIONS: These findings emphasise the need for small case load sizes and comprehensive packages of treatment in EIP services.

Understanding the identity of lived experience researchers and providers: a conceptual framework and systematic narrative review.

BACKGROUND: Identity is how we understand ourselves and others through the roles or social groups we occupy. This review focuses on lived experience researchers and providers and the impact of these roles on identity. Lived experience researchers and providers use their lived experience of mental or physical disability either as experts by experience, researchers, peer workers, or mental health professionals with lived experience. They must navigate both professional and personal aspects to their roles which can be complex. Performing roles simultaneously embodying professional and lived experiences contribute towards a lack of clarity to identity. This is not adequately explained by the theoretical evidence base for identity. MAIN BODY: This systematic review and narrative synthesis aimed to provide a conceptual framework to understand how identity of lived experience researchers and providers is conceptualised. A search strategy was entered into EBSCO to access Academic search complete, CINAHL, MEDLINE, PsycINFO, Psych Articles, and Connected papers. Out of the 2049 yielded papers, thirteen qualitative papers were eligible and synthesised, resulting in a conceptual framework. Five themes explained identity positions: Professional, Service user, Integrated, Unintegrated and Liminal. The EMERGES framework, an original conception of this review, found themes of: Enablers and Empowerment, Motivation, Empathy of the self and others, Recovery model and medical model, Growth and transformation, Exclusion and Survivor roots contributed to lived experience researcher and provider identities. CONCLUSIONS: The EMERGES framework offers a novel way to understand the identities of lived experience researchers and providers, helping support effective team working in mental health, education, and research settings.

Patients now commonly help to teach healthcare professionals from their own perspective of what it is like to experience health difficulties and healthcare services. Consequently, the needs of patients are being better recognised by healthcare providers. Patients are also involved in research. These types of patient involvement lead to improved research and care. Patients included in this type of work are frequently referred to as patient providers, service user researchers, peer workers, experts by experience or lived experience researchers and providers. This might mean they are no longer viewed as people who use services but as people who provide a service. This review helps us understand how those in these roles are affected and how they understand themselves. We found they were sometimes described as either patients or professionals. Sometimes they were described as both patient and professional at the same time. Other times they were described as somewhere between a patient or professional. There were other important ideas that affected how they viewed themselves because of these experiences. These included feelings of empowerment and motivation from doing this important teaching and clinical work. The roles gave them a better understanding of their own experiences. These roles led to a personal growth and sense of achievement. The experiences of exclusion, and of being a patient affected how patient providers think of themselves. This understanding can lead to patient providers being better understood and leads to better teaching and training of healthcare professionals.

Diagnostic Efficacy of New Xpert Ultra for Extrapulmonary Tuberculosis Using Culture and Composite Reference Standard.

Introduction: Xpert Ultra (Cepheid, USA) is recently introduced with an extra category of trace-positive results and higher sensitivity for tuberculosis (TB) diagnosis. Objective: The objective of the study was to assess the diagnostic accuracy of Xpert Ultra for extrapulmonary samples using culture and composite reference standard (CRS) as the gold standard. Materials and Methods: In a 1-year (March 2021-22) prospective observational study, samples of suspected extrapulmonary TB (EPTB) patients were subjected to Ziehl-Neelsen staining, culture, and Xpert Ultra (Cepheid, Sunnyvale, CA) tests. Relevant clinical and treatment information was noted. The diagnostic accuracy of Xpert Ultra compared with culture and CRS was calculated. Results: Out of 1720 suspected patients of EPTB, 223 (13%), predominantly males 135 (60%), with a mean age of 41.46 ± 19.81 years, were diagnosed as TB positive following CRS criteria. The maximum cases were of pleural TB (35.4%), followed by central nervous system TB (17.9%), gastrointestinal TB (17.5%), and lymph node TB (12.1%). Of all samples, 150 (8.7%) were microbiologically confirmed, including 141 detected by Xpert ultra, 67 culture positive, and only 16 smear positive. Among the Xpert Ultra-positive samples, 35 showed trace results, including six false-positive results. Considering culture and CRS as the gold standard, the sensitivity (86.57%, 59.64%) and specificity (94.98%, 99.47%) of Xpert Ultra were calculated, respectively. Rifampicin resistance was detected in 1 (0.70%) sample. Conclusion: Diagnosis of EPTB is a challenge and Xpert Ultra may detect TB at a very early stage. However, it is essential to rule out false-positive results. Additional studies are needed on Xpert Ultra to interpret trace results better.

Role of (1-3)-Β-D-Glucan Test in the Diagnosis of Invasive Fungal Infections among High-Risk Patients in a Tertiary Care Hospital.

Background Invasive fungal infections (IFI) are associated with high mortality. Serum fungal biomarkers offer an advantage over the traditional methods in early diagnosis and better clinical outcomes. The aim of the study was to evaluate the role of (1-3)-ß-D-glucan (BDG) assay in the patients suspected of IFI. Materials and Methods This prospective study was conducted in the Department of Microbiology, Dayanand Medical College and Hospital, Ludhiana, over a period of 1 year. A total of 862 serum samples were received from patients suspected of IFI, for the BDG test (Fungitell, Associates of Cape Cod Inc., USA). The test was performed as per kit protocol. Appropriate samples were processed for KOH fungal smear and fungal culture. Blood culture was done by Bactec (Biomerieux). Statistical Analysis Results were analyzed using descriptive statistical methods. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were calculated at different cutoffs. In addition, the receiver operating characteristic (ROC) curve using SPSS 21.00 software was calculated and the diagnostic accuracy was shown by the area under the ROC curve (AUC). Results Among 862 patients, 546 (63.3%) were males. The predominant age group (25.6%) was between 61 and 70 years. The most common risk factor (54.8%) was prolonged intensive care unit stay. Out of the total samples, 455 (52.8%) samples were found positive for BDG. Fungal elements were seen in 48 (10.5%) KOH smears and fungal growth was obtained in 81 (17.8%) cultures. Comparison of BDG assay and culture at different cutoffs yielded AUC-0.823. Sensitivity (100%), specificity (51.3%), accuracy (55.6%), PPV (15.8%), and NPV (100%) were observed at the kit cutoff of 80 pg/mL. Optimum sensitivity and specificity of 79.2% and 70.3%, respectively, were observed at a cutoff of 142.4pg/mL. A significant correlation was observed between BDG positivity and piperacillin-tazobactam use and dialysis. Among BDG positive patients, 38(8.4%) succumbed to death. Conclusion Detection of BDG helps in the early diagnosis of IFI in critically ill patients. As the assay has a high NPV, a negative test can be used to stop the empirical antifungal drugs. The use of a higher cutoff can be useful to avoid false-positive results.

SARS-CoV-19-associated Rhino-orbital and cerebral mucormycosis: clinical and radiological presentations.

We describe presenting clinical and imaging manifestations of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-associated Rhino-oculo-cerebral mucormycosis (ROCM) in a hospital setting during the second wave of SARS-CoV-2 pandemic in India. Data on the presenting manifestations were collected from 1 March to 31 May 2021. Associations between clinical and imaging findings were explored, specifically: (1) the presence or absence of orbital pain and infiltration of a superior orbital fissure on imaging; (2) the presence of unilateral facial nerve palsy and pterygopalatine fossa infiltration and geniculate ganglion signal on contrast magnetic resonance imaging, and (3) vision loss and optic nerve findings on imaging. Orbital pain was reported by 6/36 subjects. A fixed, frozen eye with proptosis and congestion was documented in 26 (72%), complete vision loss in 23 (64%), and a unilateral lower motor neuron facial nerve palsy in 18 (50%). No association was found between the presence of orbital pain and superior orbital fissure infiltration on imaging. The ipsilateral geniculate ganglion was found to enhance more profoundly in 7/11 subjects with facial palsy and available magnetic resonance (MR) imaging, and the ipsilateral pterygopalatine fossa was found infiltrated in 14. Among 23 subjects with complete loss of vision, 9 (39%) demonstrated long-segment bright signal in the posterior optic nerve on diffusion MR images. We conclude that orbital pain might be absent in SARS-CoV-2-associated ROCM. Facial nerve palsy is more common than previously appreciated and ischemic lesions of the posterior portion of the optic nerve underlie complete vision loss.

Unique clinical and radiological manifestations identified in the outbreak of Rhino-oculo-cerebral mucormycosis (ROCM) during the second epidemic wave of coronavirus disease 2019 (COVID-19) infection included the common occurrence of facial paralysis, frequent absence of ocular pain, and long segments of optic nerve damage.

Case Report: Plantar Cyst Caused by Phaeoacremonium inflatipes in an Immunocompetent Male, Resolving with Combination Potassium Iodide and Itraconazole Therapy.

Phaeohyphomycosis is a subcutaneous mycosis presenting as verrucous or ulcerated plaques/nodules/cysts. We report here, a case of cystic plantar phaeohyphomycosis in a 72-year-old immunocompetent man. On examination, an asymptomatic, skin colored, firm-to-soft, fluctuant, cystic lesion was seen over the left forefoot. Aspirate of lesion yielded velvety grayish-brown colonies on fungal culture, with septate, branched, phaeoid hyphae with lateral and terminal conidiophore noted on microscopic examination, and identified as Phaeoacremonium inflatipes. Due to the ongoing pandemic and advanced age, the patient declined surgical intervention and we started him on a supersaturated solution of potassium iodide (SSKI) (starting at 5 drops thrice a day and gradually increasing 1 drop per day to 20 drops thrice a day) and itraconazole (100 mg twice daily) in combination. An encouraging response was seen at 6 weeks, with complete resolution at 6 months follow-up. We report this case for the unusual fungus isolated (i.e., P. inflatipes) as well as a robust response to a combination of SSKI and itraconazole. In cases where patients refuse or are unfit for surgical excision, this combination maybe an effective therapeutic alternative.

Examining the effects of national initiatives to improve the physical health of people with psychosis in England: secondary analysis of data from the National Clinical Audit of Psychosis.

AIMS AND METHODS: To examine whether national initiatives have led to improvements in the physical health of people with psychosis. Secondary analysis of a national audit of services for people with psychosis. Proportions of patients in 'good health' according to seven measures, and one composite measure derived from national standards, were compared between multiple rounds of data collection. RESULTS: The proportion of patients in overall 'good health' under the care of 'Early Intervention in Psychosis' teams increased from 2014-2019, particularly for measures of smoking, alcohol and substance use. There was no overall change in the proportion of patients in overall 'good health' under the care of 'Community Mental Health Teams' from 2011-2017. However, there were improvements in alcohol use, blood glucose and lipid levels. CLINICAL IMPLICATIONS: There have been modest improvements in the health of people with psychosis over the last nine years. Continuing efforts are required to translate these improvements into reductions in premature mortality.

Changing microbiological profile and antimicrobial susceptibility of the isolates obtained from patients with infective endocarditis - The time to relook into the therapeutic guidelines.

The microbiological profile, associated risk factors and demographic characteristics of patients with IE has changed in the recent times. In the present study, the antibiotic susceptibility profile of 66 isolates (40 from IDU and 26 from non IDU) recovered over a period of three years from the patients with definitive diagnosis of IE along with their absolute minimum inhibitory concentrations (MIC-µg/ml) was determined as per CLSI, 2017 guidelines. Staphylococcus aureus was found to be the predominant pathogen associated with IE out of which 90.2% isolates were MRSA, although none of the isolates were found resistant to vancomycin, teicoplanin, daptomycin and linezolid. Pseudomonas aeruginosa isolates were 100% susceptible to carbapenams, however variable resistance was observed against other antimicrobials. All Enterococci were found to be 100% susceptible to linezolid and daptomycin, whereas vancomycin resistant enterococci phenotype was observed in 25% of the Enterococcal isolates. A noticeable difference in the antimicrobial susceptibility profile and their MICs were observed in the present study, as compared to published literature across the globe and within the country. However, no statistically significant difference (λ 2 test, p > 0.01)in the AST pattern of isolates from IDU vs. Non IDU was observed. After reviewing the local antibiogram it seems that we need to have our own regional guidelines, which may partially replace the currently prevailing AHA/ESC guidelines.

Understanding Identity Changes in Psychosis: A Systematic Review and Narrative Synthesis.

BACKGROUND AND OBJECTIVE: Experiencing psychosis can be associated with changes in how people see themselves as individuals and in relation to others (ie, changes in their identity). However, identity changes receive little attention in treatment, possibly due to a lack of clarity or consensus around what identity change means in people with psychosis. We aimed to create a conceptual framework synthesizing how identity changes are understood in the psychosis literature. METHODS: Electronic databases were searched up to April 2020. Studies about identity changes among people with psychotic disorders were analyzed using narrative synthesis by a collaborative review team, including researchers from different disciplines, clinicians, and people who have experienced psychosis. RESULTS: Of 10 389 studies screened, 59 were eligible. Identity changes are understood in 5 ways as (1) characteristics of psychosis, (2) consequences of altered cognitive functioning, (3) consequences of internalized stigma, (4) consequences of lost roles and relationships, and (5) reflections of personal growth. These 5 understandings are not mutually exclusive. Across a heterogeneous literature, identity changes were mostly framed in terms of loss. CONCLUSIONS: Our conceptual framework, comprising 5 understandings, highlights the complexity of studying identity changes and suggests important implications for practice and research. For clinicians, this framework can inform new therapeutic approaches where the experience and impact of identity changes are acknowledged and addressed as part of treatment. For researchers, the conceptual framework offers a way of locating their understandings of identity changes when undertaking research in this area.

Clinico-epidemiological and genomic profile of first Zika Virus outbreak in India at Jaipur city of Rajasthan state.

BACKGROUND: First Zika virus (ZIKV) positive case from North India was detected on routine surveillance of Dengue-Like Illness in an 85-year old female. Objective of the study was to conduct an investigation for epidemiological, clinical and genomic analysis of first ZIKV outbreak in Rajasthan, North India and enhance routine ZIKV surveillance. METHOD: Outbreak investigation was performed in 3 Km radius of the index case among patient contacts, febrile cases, and pregnant women. Routine surveillance was enhanced to include samples from various districts of Rajasthan. Presence of ZIKV in serum and urine samples was detected by real time PCR test and CDC trioplex kit. Few ZIKV positive samples were sequenced using the next-generation sequencing method for genomic analysis. RESULT: On outbreak investigation 153/2043 (7.48%) cases were found positive: 1/153 (0.65%) among contacts, 90/153 (58.8%) in fever cases, 62/153(40.5%) in pregnant females. In routine surveillance, 6/4722 (0.12%) serum samples were ZIKV positive.Majority of patients had mild signs and symptoms, no case of microcephaly and Guillain- Barre Syndrome was seen, 25 (40.3%) pregnant females delivered healthy babies, four (6.4%) reported abortion and three (4.8%) had intrauterine death, one (1.6%) child had colorectal malformation and died after few days of birth. ZIKV was found to belong to Asian lineage, mutation related to enhanced neuro-virulence and transmission in animal models was not found. CONCLUSION: ZIKV was endogenous to India belonging to Asian Lineage. Disease profile of the ZIKV was asymptomatic to mild. No major anomaly was observed in infants born to ZIKV positive mothers; however, long term follow up of these children is required. There is need to scale up surveillance in the virology lab network of India for early detection and control. SUMMARY LINE: Zika virus infection was endogenous due to Asian Lineage with mild disease, no case of microcephaly or Guillain- Barre Syndrome was seen but children need to be followed for anomalies and surveillance of ZIKV needs to be enhanced in the country.

Cluster containment strategy: addressing Zika virus outbreak in Rajasthan, India.

India is at risk of Zika virus transmission due to high prevalence of its vector Aedes aegypti. Rajasthan, a state in the north-west region of India, has also high prevalence of Aedes mosquito. First laboratory confirmed case of Zika virus disease in Rajasthan was reported on 21 September 2018 in Jaipur. The Government of Rajasthan quickly implemented a containment strategy to contain the outbreak and prevent further spread of this disease. Strategy included active human and mosquito surveillance, laboratory testing and sequencing of the virus, integrated vector control measures, intersectoral coordination, risk communication and social mobilisation, all in a predefined geographic area around the epicentre. Timely action with appropriate coordination at all levels with multiple stakeholders contained the outbreak successfully. In all, 159 confirmed cases were reported from in and around the 3 km containment zone in Shastri Nagar area of Jaipur City and routine surveillance. Following this, a specially developed laboratory-based surveillance strategy was put in place to ensure that the disease does not spread beyond the containment zone. No fresh case was reported subsequently within or beyond the containment zone.

Identificación de las especies de Candida en las infecciones sanguíneas / Characterization of Candida species in blood stream infections

Introducción: La candidemia se convirtió en una infección importante del torrente sanguíneo que se asocia frecuentemente con índices elevados de mortalidad y morbilidad. Las especies de Candida generan del 70% al 80% de las infecciones micóticas invasivas del torrente sanguíneo y son la cuarta causa más frecuente de infecciones hospitalarias del torrente sanguíneo. La identificación de las especies de Candida es importante, ya que las especies no albicans son cada vez más numerosas y resistentes a las drogas antimicóticas. El objetivo del estudio fue aislar e identificar diferentes especies de Candida asociadas con candidemia y analizar su patrón de susceptibilidad a los antimicóticos. Materiales y métodos: Los pacientes con sospecha de infecciones del torrente sanguíneo (ITS) fueron reclutados durante un período de un año para el estudio prospectivo. Se analizaron las características demográficas, la duración de la internación y los factores de riesgo asociados y la evolución clínica. El análisis de las muestras de sangre tuvo lugar mediante el sistema automatizado BacTAlert. La identificación y la susceptibilidad antimicótica de las levaduras fueron realizadas mediante el uso de dispositivo VITEK-2. Resultados: Las especies de Candida fueron aisladas en 30 de los 3146 cultivos recibidos (0.9%). La mayoría de los casos de candidemia tuvieron lugar en hombres (66%). Los factores de riesgo más frecuentes fueron el uso de antibióticos de amplio espectro, la vía central y la ventilación mecánica. Entre las levaduras aisladas, las especies de Candida no albicans fueron predominantes (60%), en comparación con la especie C. albicans (40%). La especie albicans presentó una susceptibilidad del 100% a los azoles y la anfotericina, en tanto que las especies no albicans fueron resistentes. De los 30 pacientes mencionados, 5 fallecieron. Conclusión: La prevalencia de Candida no albicans fue mayor en comparación con la prevalencia de Candida albicans. Las especies no albicans fueron más resistentes a los antimicóticos. En consecuencia, los pacientes internados deberían ser evaluados para identificar la candidemia.

Introduction: Candidemia has become an important bloodstream infection that is frequently associated with high rates of mortality and morbidity. Candida species account for 70-80% of invasive bloodstream fungal infections and represent the fourth most common nosocomial bloodstream infections. The identification of Candida species is important as the number of non albicans Candida species is increasing and they are becoming more resistant to antifungal drugs. The aim of the study was to isolate and identify various Candida species associated with candidemia and to study their antifungal susceptibility pattern. Materials and methods: Patients suspected of having BSI were enrolled on a one-year prospective study. Patient's demographic details, duration of hospital stay, associated risk factors and outcome were studied. Blood samples were analyzed by BacTAlert automated system. Identification and antifungal susceptibility testing of yeasts was done using VITEK-2 compact system. Results: Of 3146 blood cultures received, Candida species were isolated in 30 samples (0.9%). The majority of candidemia cases were in males (66%). The most common risk factors were use of broad spectrum antibiotics, central line and mechanical ventilation. Among the yeast isolates, non albicans Candida species were predominant (60%) compared to C. albicans (40%). Candida albicans showed 100% susceptibility to azoles and amphotericin whereas non albicans Candida species showed resistance. Of these 30 patients, 5 patients died. Conclusion: Prevalence of non albicans Candida was greater than C. albicans and cases were more resistant to antifungal drugs. Therefore surveillance for candidemia should be carried out in hospitalized patients.

Prevalence of metalo- ß-lactamase-producing (MBL) Acinetobacter species in a tertiary care hospital.

BACKGROUND AND OBJECTIVES: Acinetobacter causes a wide variety of illness in debilitated and hospitalized patients. Carbapenem resistance in Acinetobacter is an emerging problem and is a cause of concern as many nosocomial infections with Acinetobacter are resistant to most other antibiotics. The present study was aimed to study metallo-ß-lactamase (MBL) production in Acinetobacter species. MATERIALS AND METHODS: During one year prospective study, all isolates of Acinetobacter obtained from various clinical samples like respiratory, pus, blood and others were included. Antimicrobial susceptibility testing was done by standard Kirby Bauer disk diffusion method. Metallo ß-lactamase (MBL) detection was done by imipenem-EDTA combined disk method. RESULTS: Among 1017 isolates, 964 were A. baumannii, 48 were A. lwoffii and 5 were A. hemolyticus. Out of these, majority of the isolates were obtained from respiratory samples, followed by pus. A .baumannii showed high level of resistance to cephalosporins, cotrimoxazole and piperacillin. A .lwoffii and A. hemolyticus showed lesser resistance to all antibiotics. Imipenem resistance was observed in 389 (40.3 %) isolates of A.baumannii and MBL activity was seen in 80.3% of isolates. MBL positive isolates of A. baumannii showed higher resistance as compared to MBL negative isolates. CONCLUSION: This study demonstrated that multidrug resistant strains of Acinetobacter are common in tertiary care hospitals. Unwarranted and unrestricted usage of antibiotics is associated with emergence of resistance in nosocomial pathogens. Regular monitoring and documentation of carbapenem resistant is crucial in developing strategies to control infection due to these bacteria.
