Abstract
BACKGROUND In contrast to the timing of coronary angiography and percutaneous coronary intervention, the optimal timing of coronary artery bypass grafting (CABG) in non-ST-elevation myocardial infarction (NSTEMI) has not been determined. Therefore, we compared in-hospital outcomes according to different time intervals to CABG surgery in a contemporary NSTEMI population in the USA. METHODS We identified all NSTEMI hospitalizations from 2016 to 2020 where revascularization was performed with CABG. We excluded NSTEMI with high-risk features using prespecified criteria. CABG was stratified into ≤24 h, 24-72 h, 72-120 h, and >120 h from admission. Outcomes of interest included in-hospital mortality, perioperative complications, length of stay (LOS), and hospital cost. RESULTS A total of 147 170 NSTEMI hospitalizations where CABG was performed were assessed. A greater percentage of females, Blacks, and Hispanics experienced delays to CABG surgery. No difference in in-hospital mortality was observed, but CABG at 72-120 h and at >120 h was associated with higher odds of non-home discharge and acute kidney injury compared with CABG at ≤24 h from admission. In addition to these differences, CABG at >120 h was associated with higher odds of gastrointestinal hemorrhage and need for blood transfusion. All 3 groups with CABG delayed >24 h had longer LOS and hospital-associated costs compared with hospitalizations where CABG was performed at ≤24 h. CONCLUSION CABG delays in patients with NSTEMI are more frequently experienced by women and minority populations and are associated with an increased burden of complications and healthcare cost.

Abstract
The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) have previously demonstrated predictive value in coronary artery disease (CAD). We developed on an expanded, novel systemic immune-inflammation response index (SIIRI), calculated as peripheral neutrophil × monocyte × platelet ÷ lymphocyte count. We assessed 240 patients with an acute coronary syndrome that subsequently underwent percutaneous coronary intervention. CAD severity was measured using the SYNTAX score. Laboratory measurements, including cell counts, were obtained on admission. On multivariate analysis, the SIIRI was an independent predictor of severe CAD with an adjusted odds ratio (OR) of 1.666 [1.376-2.017] per 105-unit increase. The SIIRI had the highest area under the receiver operator curve of .771 [.709-.833] compared to the SII, SIRI neutrophil-lymphocyte ratio, monocyte-lymphocyte ratio, and platelet-lymphocyte ratio. The optimal cut-off for SIIRI was 4.3 × 105, with sensitivity = 69.9% and specificity = 75.8%. Increment in model performance resulting from adding SIIRI versus other inflammatory indices was assessed using discrimination, calibration, and goodness-of-fit measures. When added to a baseline model, the SIIRI resulted in a significant increase in the c-statistic and significant net reclassification index (.808, P < .0001) and integrated discrimination index (.129, P < .0001), and a decrease in Akaike and Bayesian information criteria.

Abstract
BACKGROUND Frailty and malnutrition are well-known factors influencing outcomes of myocardial infarction (MI) in older adults. Due to considerable overlap between both entities, whether the simultaneous assessment of frailty and nutrition adds nonredundant value to risk assessment is unknown. METHODS We performed a prospective cohort study on 402 patients aged at least 65 years diagnosed with ST-elevation MI that underwent percutaneous coronary intervention. Nutritional status was assessed by Controlling Nutritional Status score (CONUT), Prognostic Nutritional Index, and Geriatric Nutritional Response Index. Frailty was assessed by Clinical Frailty Scale (CFS), Derby frailty index, and acute frailty network. Primary outcome was major adverse cardiac events (MACE), comprising all-cause mortality, non-fatal MI, and unplanned repeat revascularization during 28-day follow-up. Increment in Global Registry of Acute Coronary Events (GRACE) score performance following the addition of nutrition and frailty was assessed. RESULTS The incidence of MACE was 8.02 (6.38-9.95) per 1000 person-days. The CONUT score and CFS were the best predictors of MACE and independent predictors in the multivariate Cox-regression models [hazard ratios, 2.80 (1.54-5.09) and 2.54 (1.50-4.29)]. CONUT score classified 151 (37.6%) patients as malnourished, and CFS classified 131 (32.6%) as frail. The addition of both CONUT and CFS to the GRACE score led to better model discrimination and calibration through improved c-statistic (+0.165) ( P < 0.0001) and Akaike and Bayesian information criteria. CONCLUSION Combining CONUT and CFS provides nonredundant prognostic value despite their overlapping nature. Combined nutritional and frailty screening may improve risk prognostication in older adults following MI.

Abstract
BACKGROUND The systemic immune-inflammation index (SII) is a novel parameter and its role in the prognosis of sepsis has never been explored previously. METHODS We retrospectively assessed 267 patients with blood-culture confirmed sepsis. Clinical and laboratory data recorded at intensive care unit (ICU) admission were analyzed. Outcomes of interest included in-hospital mortality and length-of-stay (LOS) in the ICU. Sequential Organ Failure Assessment (SOFA) scores, SII, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were calculated. Multivariable regression analysis was used to identify independent predictors of LOS and mortality. Area under receiver operator characteristic (AUROC) curves were used to determine optimum cutoffs, and the incremental effect of SII on the SOFA score was assessed using model discrimination and calibration properties. RESULTS There were 76 (28.5%) non-survivors. SII, NLR, and PLR were independent predictors of sepsis mortality, with adjusted odds ratios of 1.51 (1.24-1.84), 1.67 (1.30-2.13) and 1.24 (1.11-1.39). SII and SOFA score were independent predictors of LOS. SII had an AUROC of 0.848, and the optimum cutoff was 564 with a sensitivity and specificity of 85.5% and 71.2%. The addition of SII to the model had a significant incremental effect on the predictive ability of SOFA score (Net Reclassification Index = 0.084, P = 0.025; Integrated Discrimination Index = 0.056, P = 0.001). CONCLUSION The SII is an inexpensive parameter that can be used in addition to clinical sepsis scores to improve the accuracy of patient assessment.

Abstract
Objective: Breast Cancer is the leading cause of mortality and morbidity amongst Indian females. Breast self-examination (BSE) as an early detection modularity can have a profound effect on lowering mortality, if it is practiced regularly. The aim of this study was to assess the knowledge, attitude, and practice of Breast Self-examination amongst Indian women, aged 30 years and above. Methods: A validated questionnaire, consisting 35 questions measuring ‘Knowledge, Attitudes and Practice of Breast Self-Examination’ was widely circulated amongst 1000 females throughout India and responses were collected for a duration of 3 weeks, from 2nd, September 2020 to 23rd,September 2020. Results: Despite having knowledge about the technique of performing BSE, the respondents did not have a positive attitude towards it and were reluctant to practice BSE. A total of 54.4%, 15.1%, 21.3% and 9.2% of respondents were from the Northern, Southern, Western and Eastern regions of India, respectively. The overall median (IQR) KAP score was 70.0 (16.0) out of a maximum of 110. The knowledge, attitude and practice domain scores were 22.0 (5.0), 36.0 (7.0), and 13.0 (8.0) out of a maximum of 30, 52 and, 28, respectively. All three individual score domains were significantly correlated with each other and the total score.Conclusion: Despite having knowledge about the technique of performing BSE, the respondents did not have a positive attitude towards it and were reluctant to practice BSE.

Abstract
Platelet indices are inexpensive, easily accessible parameters and potentially useful prognostic indicators in sepsis. In this study we explore the differences in platelet indices and their kinetics between sepsis survivors and non-survivors. A retrospective cohort-study of 97 cases of culture-positive sepsis at a tertiary-care center in North India. Demographics, clinical and laboratory parameters at admission were assessed. Platelet count (PLT), mean-platelet-volume (MPV), platelet-distribution-width (PDW) and plateletcrit (PCT) on admission, and third, fifth and last days of hospitalization were analyzed. Fractional change in platelet indices (ΔMPV72h, ΔPDW72h, ΔPCT72h, and ΔPLT72h) by day-3 were calculated. Unpaired and paired t-tests were used to compare survivors with non-survivors, and to study the change in platelet indices with time. Logistic regression was used for multivariate analysis. ROC-curves and optimum cut-offs to predict mortality were obtained. There were 64 survivors. Non-survivors had significantly higher ΔMPV72h, ΔPDW72h, day-1 MPV and PDW, and lower ΔPLT72h. MPV and PDW increased, and PLT decreased with time among non-survivors. Trends were reversed in survivors. Only MPV and PDW showed significant change by day-3. Both were independent predictors of mortality on multivariate analysis, alongside ΔMPV72h and ΔPLT72h. On ROC analysis, MPV, PDW, ΔMPV72h, ΔPDW72h and ΔPLT72h effectively predicted mortality. Cut-off for MPV was 10.25 fL (sensitivity = 93.9%, specificity = 60.9%), and PDW, 12.6% (sensitivity = 84.8%, specificity = 51.6%). A rise in MPV and a fall in PLT was associated with mortality in this study. MPV and PDW values at admission are effective predictors of mortality and may be used in conjunction with traditional parameters.

Abstract
Background: Emerging fungal infections can pose a serious threat in contemporary healthcare due to host variations, clinical presentation and emerging resistance. Histoplasma capsulatum is a thermally dimorphic fungus, which acts as a Trojan horse by residing inside macrophages. Histoplasmosis is an emerging infection and its association with hemophagocytic lymphohistiocytosis (HLH) in immunocompetent patients has been scantily reported in the literature.
Objective. The aim of the study was to explore disseminated histoplasmosis with the help of case report.
Methods: A case report of histoid leprosy is presented.
Results: A male patient of 47 yearsof age, under treatment for chronic obstructive pulmonary disease for five years and diabetes mellitus Type-II for two years, presented with fever of unknown origin (FUO) with evidence of HLH in the bone marrow. Core biopsy of the liver and spleen showed a dense tissue infiltrate with vacuolated histiocytes containing histoplasma capsulatum, eosinophils, some lymphocytes and plasma cells.
Conclusion: Histoid leprosy is a discrete infrequent form of multibacillary leprosy with distinctive clinical, bacteriological and histomorphological features. Histopathologic examination with modified fite stain remains the mainstay of diagnosis.

Abstract
AIM To describe the parafoveal cone arrangement in emmetropic subjects and its variations with eccentricity, meridians and change in axial length in Indian eyes. METHODS We imaged 25 subjects using compact adaptive optics (AO) retinal camera prototype, the rtx1. Imaging was done at 1, 2, and 3° eccentricity from the fovea in four meridians: nasal, temporal, superior, and inferior. RESULTS A statistically significant drop in the cone packing density was observed from 2 to 3° (2° eccentricity=25 350/mm(2) (5300/mm(2), 8400-34 800/mm(2)) 3° eccentricity=20 750/mm(2) (6000 mm(2), 9000-33 670/mm(2))) P<0.05. The spacing correspondingly increased with increase in distance from the fovea (2° eccentricity=6.9 μm (0.70 μm, 5.95-11.6 μm)) and 3°eccentricity=7.80 μm (1.00 μm, 6.5-13.5 μm) P<0.05. As the axial length increases, the cone density significantly decreases. Interocular variations were noted. CONCLUSION With the advent of AO, visualization at the cellular level is now possible. Understanding the photoreceptor mosaic in the parafoveal space in terms of its density, spacing, and arrangement is crucial so as to detect early pathology and intervene appropriately. Newer therapeutic modalitites that are targeted at the cellular level like yellow micropulse laser, stem cells, gene therapy and so on may be better monitored in terms of safety and efficacy.
