RESUMEN
Aspergillus endocarditis is a rare cause of fungal endocarditis caused by the hyaline mold Aspergillus. The disease most commonly occurs in persons who are immunosuppressed and has a high mortality. Clinical presentation is often with long standing fever, embolic manifestations, and often heart murmurs. Diagnosis of aspergillus endocarditis is often delayed due to the low propensity for Aspergillus to grow in blood culture. Aspergillus endocarditis is characterized by large vegetations and also by frequently being found on the walls of the heart and not on the valves and hence can be missed if not carefully looked for. Definitive diagnosis is often by a combination of microbiological culture and histopathological examination of obtained tissue. Ancillary serological tests like galactomannan assay and polymerase chain reaction also help in the diagnosis. Treatment of aspergillus endocarditis virtually always requires a combination of prolonged antifungal therapy and surgery to enable a cure for these patients.
RESUMEN
Background: Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) is a life-threatening fungal infection. Studies focusing on CAPA in low- and middle-income countries are limited. Methods: This retrospective matched case-control study was conducted at a tertiary care center in South India. Cases of CAPA were classified using the 2020 European Confederation of Medical Mycology/International Society for Human and Animal Mycology consensus criteria. A total of 95 cases were matched 1:1 with COVID-19 patients without CAPA. Matching was done based on age and period of admission. Inverse probability weighting was used to account for imbalances in COVID-19 severity and intensive care unit (ICU) admission. Data on demographics, clinical details, microbiologic and radiologic data, and treatment outcomes were collected. A predictive score for CAPA was developed from baseline risk factors. Results: The predictive score identified lymphopenia, European Organisation for Research and Treatment of Cancer risk factors, and broad-spectrum antibiotic use as the main risk factors for CAPA. Positivity for bacterial pathogens in blood or bronchoalveolar lavage samples reduced the risk of CAPA. The predictive model performed well in cross-validation, with an area under the curve value of 82%. CAPA diagnosis significantly increased mortality and shift to ICU. Conclusions: The predictive model derived from the current study offers a valuable tool for clinicians, especially in high-endemic low- and middle-income countries, for the early identification and treatment of CAPA. With further validation, this risk score could improve patient outcomes.
RESUMEN
INTRODUCTION: Study aimed to ole of surgery along with antimicrobials to improve clinical outcomes in treating refractory cases of skull base osteomyelitis (SBO). METHODS: A prospective observational study in a tertiary care centre with 70 SBO patients meeting eligibility criteria. The study population comprised 35 patients refractory to systemic antimicrobials of at least 4 weeks duration who later underwent surgery in addition to medication (surgical group). They were compared with a medical group that responded to medications alone. The outcome variables studied were the resolution of clinical features (pain, discharge, radiology, and inflammatory markers), culture yield, and total duration of treatment. RESULTS: According to our study, relief of pain was faster in the surgical group (1.66 against 4.57 months) with statistical significance (p < 0.001). Relief of symptoms (p < 0.001), radiological improvement (p = 0.001), and normalising of inflammatory markers (p < 0.001) were better in the surgical group than in the medical group. The duration of treatment was an average of 9.2 months in the surgical group compared to 11.3 months in the medical group (p = 0.019). Microbial culture from deep tissue sampling was positive in 24 surgical patients (68.57%). CONCLUSIONS: The treatment response in selected patients of refractory SBO who underwent surgery along with antimicrobials was better than the group who responded to antimicrobials alone. Surgery provided higher microbial yield resulting in culture-specific antimicrobials. The surgical group observed faster relief of symptoms, reduced hospital stay, and total treatment duration.

A male in his 40's with no known comorbidities developed severe COVID-19 pneumonia and received a four-week course of methylprednisolone. The patient subsequently developed disseminated Aspergillus endocarditis, manifesting as multiple organ involvement including the heart, eyes, and brain. Despite the poor prognosis generally associated with fungal endocarditis, the patient survived following aggressive medical management with a combination of liposomal amphotericin b and voriconazole therapy and is now doing well for over two years and is off antifungal therapy for a year.
RESUMEN
OBJECTIVE: Studies evaluating the incidence, source, and preventability of hospital-onset bacteremia and fungemia (HOB), defined as any positive blood culture obtained after 3 calendar days of hospital admission, are lacking in low- and middle-income countries (LMICs). DESIGN, SETTING, AND PARTICIPANTS: All consecutive blood cultures performed for 6 months during 2020-2021 in 2 hospitals in India were reviewed to assess HOB and National Healthcare Safety Network (NHSN) reportable central-line-associated bloodstream infection (CLABSI) events. Medical records of a convenience sample of 300 consecutive HOB events were retrospectively reviewed to determine source and preventability. Univariate and multivariable logistic regression analyses were performed to identify factors associated with HOB preventability. RESULTS: Among 6,733 blood cultures obtained from 3,558 hospitalized patients, there were 409 and 59 unique HOB and NHSN-reportable CLABSI events, respectively. CLABSIs accounted for 59 (14%) of 409 HOB events. There was a moderate but non-significant correlation (r = 0.51; P = .070) between HOB and CLABSI rates. Among 300 reviewed HOB cases, CLABSIs were identified as source in only 38 (13%). Although 157 (52%) of all 300 HOB cases were potentially preventable, CLABSIs accounted for only 22 (14%) of these 157 preventable HOB events. In multivariable analysis, neutropenia, and sepsis as an indication for blood culture were associated with decreased odds of HOB preventability, whereas hospital stay ≥7 days and presence of a urinary catheter were associated with increased likelihood of preventability. CONCLUSIONS: HOB may have utility as a healthcare-associated infection metric in LMIC settings because it captures preventable bloodstream infections beyond NHSN-reportable CLABSIs.

BACKGROUND: With the World Health Organization (WHO) declaring an end to the COVID-19 pandemic, the focus has shifted to understanding and managing long-term post-infectious complications. "Long COVID," characterized by persistent or new onset symptoms extending beyond the initial phase of infection, is one such complication. This study aims to describe the incidence, clinical features and risk profile of long COVID among individuals in a South Indian cohort who experienced post-ChAdOx1 n-Cov-2 vaccine breakthrough infections. METHODS: A single-centre hospital-based prospective observational study was conducted from October to December 2021. The study population comprised adult patients (> 18 years) with a confirmed COVID-19 diagnosis who had received at least a single dose of vaccination. Data was collected using a specially tailored questionnaire at week 2, week 6, and week 12 post-negative COVID-19 test. A propensity score based predictive scoring system was developed to assess the risk of long COVID. RESULTS: Among the 414 patients followed up in the study, 164 (39.6%) reported long COVID symptoms persisting beyond 6 week's post-infection. The presence of long COVID was significantly higher among patients above 65 years of age, and those with comorbidities such as Type II Diabetes Mellitus, hypertension, dyslipidemia, coronary artery disease, asthma, and cancer. Using backwards selection, a reduced model was developed, identifying age (OR 1.053, 95% CI 0.097-1.07, p < 0.001), hypertension (OR 2.59, 95% CI 1.46-4.59, p = 0.001), and bronchial asthma (OR 3.7176, 95% CI 1.24-11.12, p = 0.018) as significant predictors of long COVID incidence. A significant positive correlation was observed between the symptomatic burden and the number of individual comorbidities. CONCLUSIONS: The significant presence of long COVID at 12 weeks among non-hospitalised patients underscores the importance of post-recovery follow-up to assess for the presence of long COVID. The predictive risk score proposed in this study may help identify individuals at risk of developing long COVID. Further research is needed to understand the impact of long COVID on patients' quality of life and the potential role of tailored rehabilitation programs in improving patient outcomes.

A 68-year-old female, with a known case of mantle cell lymphoma, came with complaints of persistent cough with expectoration for three months, not responding to multiple courses of antibiotics. Bronchoscopy was done and bronchoalveolar lavage (BAL) culture revealed Penicillium species. She was started on IV liposomal amphotericin B for 14 days and then switched to oral itraconazole which showed a response to treatment. Early diagnosis of penicilliosis and prompt treatment are important as it is rare and associated with a high mortality rate.
RESUMEN
BACKGROUND: Long COVID, or post-COVID-19 syndrome, is the persistence of signs and symptoms that develop during or after COVID-19 infection for more than 12 weeks and are not explained by an alternative diagnosis. In spite of health care recouping to prepandemic states, the post-COVID-19 state tends to be less recognized from low- and middle-income country settings and holistic therapeutic protocols do not exist. Owing to the syndemic nature of COVID-19, it is important to characterize post-COVID-19 syndrome. OBJECTIVE: We aimed to determine the incidence of post-COVID-19 symptoms in a cohort of inpatients who recovered from COVID-19 from February to July 2021 at a tertiary-care center in South India. In addition, we aimed at comparing the prevalence of post-COVID-19 manifestations in intensive care unit (ICU) and non-ICU patients, assessing the persistence, severity, and characteristics of post-COVID-19 manifestations, and elucidating the risk factors associated with the presence of post-COVID-19 manifestations. METHODS: A total of 120 adult patients admitted with COVID-19 in the specified time frame were recruited into the study after providing informed written consent. The cohort included 50 patients requiring intensive care and 70 patients without intensive care. The follow-up was conducted on the second and sixth weeks after discharge with a structured questionnaire. The questionnaire was filled in by the patient/family member of the patient during their visit to the hospital for follow-up at 2 weeks and through telephone follow-up at 6 weeks. RESULTS: The mean age of the cohort was 55 years and 55% were men. Only 5% of the cohort had taken the first dose of COVID-19 vaccination. Among the 120 patients, 58.3% had mild COVID-19 and 41.7% had moderate to severe COVID-19 infection. In addition, 60.8% (n=73) of patients had at least one persistent symptom at the sixth week of discharge and 50 (41.7%) patients required intensive care during their inpatient stay. The presence of persistent symptoms at 6 weeks was not associated with severity of illness, age, or requirement for intensive care. Fatigue was the most common reported persistent symptom with a prevalence of 55.8%, followed by dyspnea (20%) and weight loss (16.7%). Female sex (odds ratio [OR] 2.4, 95% CI 1.03-5.58; P=.04) and steroid administration during hospital stay (OR 4.43, 95% CI 1.9-10.28; P=.001) were found to be significant risk factors for the presence of post-COVID-19 symptoms at 6 weeks as revealed by logistic regression analysis. CONCLUSIONS: Overall, 60.8% of inpatients treated for COVID-19 had post-COVID-19 symptoms at 6 weeks postdischarge from the hospital. The incidence of post-COVID-19 syndrome in the cohort did not significantly differ across the mild, moderate, and severe COVID-19 severity categories. Female sex and steroid administration during the hospital stay were identified as predictors of the persistence of post-COVID-19 symptoms at 6 weeks.
RESUMEN
Background: Patients undergoing solid organ transplantation are at a higher risk of multi-drug resistant (MDR) bacterial infections especially during the immediate post operative period. Objective: To audit the usage, dosage appropriateness and safety of colistin use in abdominal solid organ transplant recipients to treat immediate post-transplant bacterial infections. Methods: After completion of 1000 abdominal solid organ transplants at our institute, data of the transplant recipients who received colistin between October 2010 and December 2019 was extracted from the hospital health information system. Data of all microbiological culture isolates, the minimum inhibitory concentration (MIC) of colistin, appropriateness of colistin dosing and nephrotoxicity associated with colistin use was assessed. Results: Of the 1170 (732 liver and 438 renal) solid organ transplant recipients, 82 (66 liver and 16 renal) received colistin to treat posttransplant MDR bacterial infections. Nearly 60% received colistin as definitive therapy and 87.81% received colistin as combination. Mean duration of colistin therapy was found to be higher in renal than liver transplant recipients. Out of the total 89 bacterial isolates, there were 2 colistin resistant Klebsiella strains. Colistin in combination with meropenem (36.4%) was the most commonly used dual therapy. Out of the total 89 bacterial isolates, there were 2 colistin resistant Klebsiella strains. Overall in-hospital mortality of patients who received colistin was 43.9%. Renal impairment occurred in 28.8% of liver transplant recipients. Conclusion: Infection necessitating colistin use increases mortality by three folds in liver transplant recipients and by five percentage points in renal transplant recipients.

The study aims to characterize community-acquired sepsis patients admitted to our 1300-bedded tertiary care hospital in South India from the Surviving Sepsis Campaign (SSC) guideline-compliant e-sepsis registry stratified by focus of infection. The prospective observational study recruited 1009 adult sepsis patients presenting to the emergency department at the center based on Sepsis-2 criteria for a period of three years. Of the patients, 41% were between 61 and 80 years with a mean age of 57.37 ± 13.5%. A total of 13.5% (136) was under septic shock and in-hospital mortality for the study cohort was 25%. The 3 h and 6 h bundle compliance rates observed were 37% and 49%, respectively, without significant survival benefits. Predictors of mortality among patients with bloodstream infections were septic shock (p = 0.01, OR 2.4, 95% CI 1.23-4.79) and neutrophil-to-lymphocyte ratio (p = 0.008, OR 1.01, 95% CI 1.009-1.066). The presence of Acinetobacter (p = 0.005, OR 4.07, 95% CI 1.37-12.09), Candida non-albicans (p = 0.001, OR16.02, 95% CI 3.0-84.2) and septic shock (p = 0.071, OR 2.5, 95% CI 0.97-6.6) were significant predictors of mortality in patients with community-acquired pneumonia. The registry has proven to be a key data source detailing regional microbial etiology and clinical outcomes of adult sepsis patients, enabling comprehensive evaluation of regional community-acquired sepsis to tailor institutional sepsis treatment protocols.
RESUMEN
Background: Vaccination is the most important prophylactic measure taken to curb COVID-19 pandemics. This study was undertaken to throw light on the safety of Covishield vaccine among health care workers (HCWs) and to assess the co-variates associated with incidence of adverse events. Methods: This prospective observational study was conducted in a tertiary care center in South India as part of the HCW vaccination drive. All consenting HCWs who received the first dose of Covishield vaccine and developed ADRs were included in this study. After vaccination, all beneficiaries were monitored for AEFI for a period of half an hour and later followed up through telephone and google survey forms on day 2 and day 7 of vaccination. The data was subsequently collated into spreadsheet format and analyzed. Results: The study included 1264 consenting healthcare workers who were predominantly youth, aged 15-24 years (n = 583, 46 %) and with a female preponderance of 76 % (n = 960). Past history of COVID-19 infections was reported among 4.6 % (58) of the study population. Postvaccination symptoms were majorly reported during the first (40 %) and second day (44 %) after vaccination with a high prevalence of both local (n = 1083, 85 %) and systemic symptoms (n = 1065, 84 %). The mean duration of symptoms was observed to be 1.4 ± 0.81 days post vaccination. Symptoms were observed significantly high among females (76.7 %, p = 0.013). The prevalence of systemic (88 % vs 80 %) (p < 0.001) and allergic symptoms (7 % vs 3 %; p = 0.03) were observed to be significantly high among respondents with <25 years of age. The systemic and allergic symptoms following vaccination were reported to be low among healthcare workers who had a previous history of COVID-19 infection. Conclusion: COVID vaccination has been observed to be safe and well tolerated with more systemic symptoms reported among younger age group and females.
RESUMEN
The post-Covid symptoms among patients hospitalised with covid has to be determined for elucidating the spectrum of illness which persists even after the apparent recovery. The understanding of the post-Covid symptoms will help us to better manage aftermath of the pandemic. Our aim is to determine the incidence of post-Covid symptoms in a cohort of inpatients who recovered from COVID-19 from a tertiary care centre in South India. MATERIAL: 120 survivors from patients admitted with COVID 19 were prospectively followed up for 6 weeks after their discharge from the hospital. The cohort included 50 patients requiring Intensive care unit (ICU) care and 70 ward patients. The follow-up was conducted on the second and sixth week after discharge with a structured questionnaire. The questionnaire was filled by the patient/ bystanders during their visit to the hospital for follow-up at 2 weeks and through telephone follow up at 6 weeks. OBSERVATION: Mean age of the cohort was 55 years and 55% were males. 58.3% had mild covid and 41.7% had moderate to severe covid infection. 60.8% (n=73) of patients had at least one persistent symptom at sixth week of discharge. 50 (41.7%) patients required intensive care during their inpatient stay. Presence of persistent symptoms at 6 weeks was not associated with severity of illness, age or requirement for intensive care. Fatigue was the most common reported persistent symptom with a prevalence of 55.8% followed by weight loss (22.5%) and dyspnoea (20%). Female sex (OR 2.4, 95% CI: 1.03-5.58, p = 0.041) and steroid administration during hospital stay (OR: 4.43; 95% CI: 1.9-10.28, p = 0.001), were found to be significant risk factors for the presence of post-Covid symptoms at 6 weeks as revealed by logistic regression analysis. CONCLUSION: 60.8% of inpatients treated for covid had post-Covid symptoms at 6 weeks post- discharge from hospital. Female sex and steroid administration during hospital stay were identified as predictors of persistence of post-Covid symptoms at 6weeks.

ABSTRACT: Management of candidemia in developing countries like India encounters laxity in appropriate clinical management and challenges in terms of healthcare capacity, despite its association with high morbidity and mortality. Our study aims to evaluate the impact of a comprehensive candidemia care bundle implementation on appropriateness of therapy and major clinical outcomes.The single-center, quasi-experimental study conducted at a south Indian tertiary care center included adult patients diagnosed with candidemia. Following a retrospective review of candidemia patients of the pre-implementation period (January 2013-December 2015), the hospital antifungal stewardship team instituted a clinical pharmacist driven comprehensive candidemia care bundle for candidemia patients during the post-implementation period (October 2017-2019) and its impact on appropriateness of antifungal prescriptions and inpatient mortality was evaluated.The study included 175 patients with candidemia, comprising of 103 patients in the pre-implementation period and 72 patients in the post-implementation period. Appropriateness of antifungal prescriptions rose to 65% during post-implementation period from 30% observed in pre-implementation phase (Pâ=â.0005). The inhospital mortality rate reduced from 40% in the pre-implementation phase to 36% in the post-implementation phase, recording a 10% reduction over 2âyears post-implementation (Pâ=â.26). No significant difference was observed in terms length of stay (Pâ=â.17).Our study demonstrates the successful implementation of an antifungal stewardship led comprehensive care bundle in a low middle income countries setting. The results of our study will have profound implications in improving the appropriateness of management of candidemia and feasibility of scaling up to wider settings could be explored.

THE PROBLEM CONSIDERED: This multi-centric study analyzed data of COVID-19 patients and compared differences in symptomatology, management, and outcomes between vaccinated and vaccine-naive patients. METHODS: All COVID-19 positive individuals treated as an in-or out-patient from the 1stMarch to 15th May 2021 in four selected study sites were considered for the study. Treatment details, symptoms, and clinical course were obtained from hospital records. Chi-square was used to test the association of socio-demographic and treatment variables with the vaccination status and binary logistic regression were used to obtain the odds ratio with a 95% confidence interval. RESULTS: The analysis was of 1446 patients after exclusion of 156 with missing data of which males were 57.3% and females 42.7%. 346 were vaccinated; 189 received one dose and 157 both doses. Hospitalization was more in vaccinated (38.2% vs 27.4%); ICU admissions were less in vaccinated (3.5% vs 7.1%). More vaccinated were symptomatic (OR = 1.5); half less likely to be on non-invasive ventilation (OR = 0.5) while vaccine naive patients had 4.21 times the risk of death. CONCLUSION: Severe infection, duration of hospital stays, need for ventilation and death were significantly less among vaccinated when compared with vaccine naive patients.
RESUMEN
Sepsis is a serious cause of morbidity and mortality and yet its pathophysiology remains elusive. Recently, medical and technological advances have helped redefine the criteria for sepsis incidence, which is otherwise poorly understood. With the recording of clinical parameters and outcomes of patients, enabling technologies, such as machine learning, open avenues for early prognostic systems for sepsis. In this work, we propose a two-phase approach towards prognostic scoring by predicting two outcomes in sepsis patients - Sepsis Severity and Comorbidity Severity. We train and evaluate multiple machine learning models on a dataset of 80 parameters collected from 800 patients at Amrita Institute of Medical Sciences, Kerala, India. We present an analysis of these results and harmonize consistencies and/or contradictions between elements of human knowledge and that of the model, using local interpretable model-agnostic explanations and other methods.

BACKGROUND: In autoimmune inflammatory rheumatological diseases, routine cardiovascular risk assessment is becoming more important. As an increased cardiovascular disease (CVD) risk is recognized in patients with fibromyalgia (FM), a combination of traditional CVD risk assessment tool with Machine Learning (ML) predictive model could help to identify non-traditional CVD risk factors. METHODS: This study was a retrospective case-control study conducted at a quaternary care center in India. Female patients diagnosed with FM as per 2016 modified American College of Rheumatology 2010/2011 diagnostic criteria were enrolled; healthy age and gender-matched controls were obtained from Non-communicable disease Initiatives and Research at AMrita (NIRAM) study database. Firstly, FM cases and healthy controls were age-stratified into three categories of 18-39 years, 40-59 years, and ≥ 60 years. A 10 year and lifetime CVD risk was calculated in both cases and controls using the ASCVD calculator. Pearson chi-square test and Fisher's exact were used to compare the ASCVD risk scores of FM patients and controls across the age categories. Secondly, ML predictive models of CVD risk in FM patients were developed. A random forest algorithm was used to develop the predictive models with ASCVD 10 years and lifetime risk as target measures. Model predictive accuracy of the ML models was assessed by accuracy, f1-score, and Area Under 'receiver operating Curve' (AUC). From the final predictive models, we assessed risk factors that had the highest weightage for CVD risk in FM. RESULTS: A total of 139 FM cases and 1820 controls were enrolled in the study. FM patients in the age group 40-59 years had increased lifetime CVD risk compared to the control group (OR = 1.56, p = 0.043). However, CVD risk was not associated with FM disease severity and disease duration as per the conventional statistical analysis. ML model for 10-year ASCVD risk had an accuracy of 95% with an f1-score of 0.67 and AUC of 0.825. ML model for the lifetime ASCVD risk had an accuracy of 72% with an f1-score of 0.79 and AUC of 0.713. In addition to the traditional risk factors for CVD, FM disease severity parameters were important contributors in the ML predictive models. CONCLUSION: FM patients of the 40-59 years age group had increased lifetime CVD risk in our study. Although FM disease severity was not associated with high CVD risk as per the conventional statistical analysis of the data, it was among the highest contributor to ML predictive model for CVD risk in FM patients. This also highlights that ML can potentially help to bridge the gap of non-linear risk factor identification.

BACKGROUND: Candida auris infections are an emerging global threat with poor clinical outcome, high mortality rate, high transmission rate and outbreak potential. The objective of this work is to describe a multidisciplinary approach towards the investigation and containment of a Candida auris outbreak and the preventive measures adopted in a resource limited setting. METHODS: This outbreak investigational study was conducted at a 1300-bedded tertiary care academic hospital in South India. The study included 15 adult inpatients with laboratory confirmed Candida auris isolates. The outbreak cluster was identified in adult patients admitted from September 2017 to 2019. The system response consisted of a critical alert system for laboratory confirmed Candida auris infection and multidisciplinary 'Candida auris care team' for patient management. The team implemented stringent Infection Prevention and Control (IPC) measures including patient cohorting, standardized therapy and decolonization, staff training, prospective surveillance and introduction of Candida auris specific care bundle. RESULTS: Two outbreak clusters were identified; first cluster occurring between October and November 2017 and the second cluster in May 2018. The cohorts consisted of 7 and 8 Candida auris positive patients in the first and second waves of the outbreak respectively with a total survival rate of 93% (14/15). Deployment of containment measures led to gradual decline in the incidence of adult Candida auris positive cases and prevented further cluster formation. CONCLUSIONS: The sustained implementation of guideline and evidence-based IPC measures and training of healthcare workers for improving awareness on systematically following standardized protocols of Candida auris related IPC practices successfully contained Candida auris outbreaks at our hospital. This demonstrates the feasibility of establishing a multidisciplinary model and bundling of practices for preventing Candida auris outbreaks in a Low- and Middle-income country.

Polymyxins being last resort drugs to treat infections triggered by multidrug-resistant pathogens necessitates the implementation of antimicrobial stewardship program (ASP) initiatives to support its rational prescription across healthcare settings. Our study aims to describe the change in the epidemiology of polymyxins and patient outcomes following the implementation of ASP at our institution. The antimicrobial stewardship program initiated in February 2016 at our 1300 bed tertiary care center involved post-prescriptive audits tracking polymyxin consumption and evaluating prescription appropriateness in terms of the right indication, right frequency, right drug, right duration of therapy and administration of the right loading dose (LD) and maintenance dose (MD). Among the 2442 polymyxin prescriptions tracked over the entire study period ranging from February 2016 to January 2020, the number of prescriptions dropped from 772 prescriptions in the pre-implementation period to an average of 417 per year during the post-implementation period, recording a 45% reduction. The quarterly patient survival rates had a significant positive correlation with the quarterly prescription appropriateness rates (r = 0.4774, p = 0.02), right loading dose (r = 0.5228, p = 0.015) and right duration (r = 0.4361, p = 0.04). Our study on the epidemiology of polymyxin use demonstrated favorable effects on the appropriateness of prescriptions and mortality benefits after successful implementation of antimicrobial stewardship in a real-world setting.
RESUMEN
BACKGROUND: Sepsis remains a leading cause of death worldwide despite advances in management strategies. Preclinical and observational studies have found mortality benefit with high-dose vitamin C in sepsis. Our study aims to prospectively evaluate the effect of intravenous hydrocortisone, vitamin C [ascorbic acid (AA)], and thiamine (HAT) administration in reducing inpatient all-cause mortality among patients with septic shock. MATERIALS AND METHODS: Our single-center, prospective, open-label, randomized controlled trial recruited patients with admitting diagnosis of septic shock and assigned eligible patients (1:1) into either intervention (HAT) or control group (routine). The HAT group received intravenous combination of vitamin C (1.5 g every 6 hours), thiamine (200 mg every 12 hours), and hydrocortisone (50 mg every 6 hours) within 6 hours of onset of septic shock admission. The treatment was continued for at least 4 days, in addition to the routine standard of care provided to the control group. Thiamine and hydrocortisone use in control arm was not restricted. Vitamin C levels were estimated at baseline and at the end of the 4 days of treatment for both groups. The primary outcome evaluated was mortality during inpatient stay. RESULTS: Among 90 patients enrolled, 88 patients completed the study protocol. The baseline characteristics between the HAT (n = 45) and the routine (n = 43) groups were comparable. The all-cause mortality in the HAT cohort was 57% (26/45) compared to 53% (23/43) in the routine care group (p = 0.4, OR 1.19, 95% CI 0.51-2.76). The time to reversal of septic shock was significantly lower in the HAT (34.58 ± 22.63 hours) in comparison to the routine care (45.42 ± 24.4 hours) (p = 0.03, mean difference -10.84, 95% CI -20.8 to -0.87). No significant difference was observed between the HAT and the routine care with respect to changes in sequential organ failure assessment (SOFA) scores at 72 hours (2.23 ± 2.4 vs 1.38 ± 3.1), the use of mechanical ventilation (48% vs 46%), and mean Vasoactive Inotropic Score (7.77 ± 12.12 vs 8.86 ± 12.5). CONCLUSION: Intravenous administration of vitamin C, thiamine, and hydrocortisone did not significantly improve the inpatient all-cause mortality among patients with septic shock. CLINICAL SIGNIFICANCE: HAT protocol does not reduce hospital mortality but decreases time to shock reversal in septic shock.

RESUMEN
COVID 19 pandemic has affected the delivery of surgical services as a part of management of head and neck cancers all over the world. Since it may affect the overall cure as well as quality of life of these patients, it is necessary to continue providing surgical treatment but with minimal additional health hazards to the patient or the health care worker. For this, a workflow was formulated in a university teaching hospital in India with large head and neck cancer workload and implemented during the period of national lockdown. 125 major head and neck cancer cases were operated during this period out of which 25 patients were of high-risk status. Emergency (10%) and semi-emergency (83%) cases predominated with few electives. The number of noncancer reconstructive and craniomaxillofacial cases operated was 81, out of which 25% was of emergency in nature. When compared to the data of similar period in the previous year, 60% of the workload in the cancer-related cases could be offered surgical treatment, whereas the noncancer cases operated were only 25%. The workflow may be useful for all surgical departments in safely performing procedures during this pandemic or similar situations in future with suitable refinements.
