Diabetic ketoacidosis (DKA) is an acute and major complication of diabetes mellitus (DM), both type I and type II. Biochemically, DKA consists of a triad of blood sugar levels greater than 250 mg/dL, ketonemia of greater than 3 mmol/L and/or significant ketonuria, and a blood pH less than 7.3 with an increased anion gap. Currently, the sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are widely used in management of type II diabetes. There have been several reports of an association between euglycemic diabetic ketoacidosis (EuDKA) and SGLT-2i agents. We present three different patients who were on SGLT-2i therapy who developed recurrent EuDKA postprocedure or sepsis. We believe that prolonged treatment (5-6 days) with intravenous (IV) insulin with glucose until resolution of glycosuria can be considered as an inexpensive marker of resolution of EuDKA. Moreover, the recommended duration for discontinuation of these drugs prior to elective procedures should be longer than 3 days. How to cite this article: Shah M, Pathrose E, Bhagwat NM, Chandy D.

Aerococci are fastidious, gram-positive Streptococcus-like organisms widely distributed in the hospital environment. Aerococcus viridans is primarily an opportunistic pathogen. Very few cases of A. viridans bacteremia have been reported so far probably because of its misidentification as streptococci. Here we report an interesting case of A. viridans bacteremia.

Diabetic ketoacidosis (DKA) is the most serious hyperglycemic emergency in patients with type I diabetes mellitus and is associated with significant morbidity and mortality. DKA may be a life-threatening condition due to severe clinical and biological impairments and treatment-associated complications [cerebral edema, acute respiratory failure, acute renal failure (ARF), hypokalemia, hypophosphatemia]. The development of ARF with rhabdomyolysis is a rare but potentially lethal disorder in children with DKA with an estimated mortality of about 50%. Continuous renal replacement therapy is commonly used in intensive care units to provide renal replacement and fluid management. We successfully treated a 13-year-old boy with continuous venovenous hemodiafiltration, who had been diagnosed with severe DKA, complicated with hypophosphatemia-induced acute respiratory failure, rhabdomyolysis and ARF, persistent acidosis, and coma.

Background and aims: With the rise of coronavirus disease-2019 (COVID-19) cases globally, the infection among frontline healthcare workers (HCWs) escalates many folds. There is, however, limited literature from low middle-income countries regarding risk factors for COVID-19 infection in HCWs. We conducted a case-control study to evaluate the risk factors of COVID-19 infection to HCWs.

Materials and methods: This case-control study was conducted in a designated COVID-19 hospital. Eighty-one HCWs involved in direct care of COVID-19 patients, identified as cases, and 266 were recruited as controls. Telephonic interviews with participants were conducted, and information regarding demographic variables, chemoprophylaxis, exposure to infected patients, and adherence to infection prevention and control (IPC) measures was collected.

Results: We observed a statistically significant difference in the number of times training session for IPC measures attended by HCWs (p = 0.02), performance of aerosol-generating medical procedures (AGMPs) (p <0.001), practices of donning and doffing of personal protective equipment (PPE) (p <0.001), hand hygiene (p <0.001), and decontamination of highly touched surfaces (p <0.001). Logistic regression analysis revealed if the decontamination of highly touched surfaces is decreased by one unit, the odds of getting COVID-19 infection is multiplied by a factor of 0.41 and AGMPs decrease the risk of being a case by 0.76.

Conclusion: This study highlighted that inadequate observation of IPC methods increases the risk of COVID-19 infection to frontline HCWs, whereas performance of AGMPs does not enhance the risk. In this study, HCWs undertaking an AGMP, because of concern of acquiring infection, were more diligent during procedures and hence had lesser infection.

Background: Peripheral blood neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a prognostic biomarker in many disease states. The aim of this study was to evaluate the diagnostic utility of NLR to predict poor functional outcomes in patients with hemorrhagic stroke and to compare it with the intracranial hemorrhage (ICH) score.

Materials and methods: Patients who presented to the emergency department with clinical features suggestive of stroke were evaluated with computed tomography (CT) brain to identify ICH. The ICH scores and NLR were estimated at the time of admission. Modified Rankin Scale (mRS) score equal to or greater than 3 at 90 days was used to define poor functional outcomes (major disability or death). Receiver operating characteristic (ROC) curve was plotted with NLR and the ICH score to analyze and compare their discriminative ability to predict poor functional outcomes.

Results: A total of 158 patients were recruited for the study. One hundred and seven patients were found to have poor functional outcomes as per their mRS score at 90 days. The mean NLR and the ICH scores at presentation were significantly higher for the poor outcome group (6.57 and 2.83) compared to the good outcome group (2.75 and 1.49). The ROC analysis revealed that both NLR and the ICH scores were good predictors of functional outcomes at 90 days with area under the curve (AUC) of 0.814 and 0.819, respectively. The sensitivity and specificity of NLR were 84 and 66.3% and those of the ICH score were 66.7 and 78.3% to predict poor functional outcomes.

Conclusion: In patients with hemorrhagic stroke, NLR at admission is a good predictor of functional outcomes at 90 days. When compared to the ICH score, NLR is more sensitive but less specific in predicting poor functional outcomes.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection affects the cardiovascular system at many levels. It initially infects endothelial cells, inducing marked endothelial damage and inflammation. However, there was no empirical evidence of functional compromise of arterial walls.

Aims and objective: Our primary objective was to study functional arterial damage in coronavirus disease 2019 (COVID-19) and establish the noninvasive measurement of arterial stiffness as an independent marker of disease severity.

Materials and methods: We recorded the arterial stiffness of 23 mild, 21 moderate, and 20 severe COVID-19 patients grouped on the latest National Institute of Health (NIH) severity criteria. We observed arterial stiffness of COVID-19 patients with standard parameters like noninvasive estimated carotid-femoral pulse wave velocity (cfPWV), age-normalized increase in cfPWV (ANI_cfPWV), age-normalized increase in aortic augmentation pressure (ANI_AugP), and heart rate-normalized augmentation index (HRN_ AIx). All the parameters were also corrected for statistically significant confounding factors.

Results: Moderate and severe COVID-19 patients have extremely significantly elevated arterial stiffness than mild patients. In mild patients, cfPWV (829.1 ± 139.2 cm/second) was significantly lower than both moderate (1067 ± 152.5 cm/second, p <0.0001) and severe (1416 ± 253.9 cm/second, p <0.0001) patients. ANI_cfPWV in moderate and severe patients was significantly higher than mild patients (mild: 101.2 ± 126.1 cm/second; moderate: 279 ± 114.4 cm/second; severe: 580.1 ± 216.4 cm/second; intergroup p <0.0001). The results even after correction for significant confounding factors did not show any considerable change in the increasing trend of arterial stiffness.

Conclusion: This study establishes the functional deterioration of arteries in proportion to the severity of COVID-19.

Introduction: Intensive care unit (ICU) admission is required for approximately 25% of patients affected with coronavirus disease-19 (COVID-19) and imposes a high economic burden on patients in resource-limited settings.

Method: We conducted a retrospective direct medical care cost analysis of COVID-19 patients requiring ICU admission after obtaining the Institutional Ethics Committee approval. Data were obtained from the records of patients admitted to the COVID-19 ICU of a tertiary care trust teaching hospital from June 2020 to December 2020. Direct costs were analyzed and correlated with various demographic variables and clinical outcomes.

Results: A total of 176 patients were included (males-76%). The median direct medical cost for a median stay of 13 days was INR 202248.5 ($ 2742.91). Hospital drugs and disposables accounted for 20% of the total cost followed by bed charges (19%), equipment charges (17%), biosafety protective gear (15.5%), pathological and radiological tests (15%), clinical management (7.6%), and biomedical waste management (1.6%). Government schemes accounted for 79% of medical claims followed by directly paying patients (12.5%) and private insurance (8.5%). The cost was significantly higher in patients with diabetes mellitus and sepsis and in those requiring mechanical ventilation (MV) (p <0.05). Shorter lead time to hospital admission and lesser length of hospital stay were associated with significant lower direct cost.

Conclusion: Direct medical care cost is substantial for COVID-19 patients requiring ICU admission. This cost is significantly associated with increased ICU and hospital stay, longer lead time to admission, diabetes mellitus, sepsis, and those who need high-flow nasal cannula (HFNC), noninvasive ventilation (NIV), and MV.

Background: To investigate the levels of neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios in those having a pulmonary embolism (PE) in the course of coronavirus disease 2019 (COVID-19).

Methods: The records of those having COVID-19 were retrospectively obtained from the hospital automation system. NLR and PLR were measured with the help of patients' blood cell counts.

Results: Of 1,452 COVID-19 patients, 17 (1.2%) were diagnosed with PE. Compared with the controls, while leukocyte (p = 0.001), neutrophil (p <0.001), and neutrophil percentages, (p = 0.001) and NLR (p <0.001) and PLR (p = 0.006) had higher values, lymphocyte count (p = 0.004) and lymphocyte percentage (p <0.001) showed lower values in the patients with PE.Compared to the survivors, the non-survivors were found to have increased leukocyte (p <0.001), neutrophil (p <0.001), and neutrophil percentages (p <0.001), NLR (p <0.001) and PLR (p <0.001), and decreased lymphocyte (p <0.001) counts and percentage (p <0.001), hemoglobin (p = 0.005), hematocrit (p = 0.012), and platelet counts (p <0.001).While NLR and PLR cutoffs were found as 4.338 and 187.83 in predicting PE, the cutoff values of NLR and PLR were, respectively, 4.301 and 172.5 in predicting mortality.The logistic regression analysis also revealed that all hematological parameters had no effects on the development of PE.

Conclusion: Although NLR and PLR had higher scores in PE patients, no relationship was determined between the levels of NLR and PLR and PE development. Further prospective studies including larger populations are required to enlighten the increased NLR and PLR in PE patients having COVID-19.

Background: To evaluate the association of thyroid hormones changes, including increased reverse triiodothyronine (rT3) level, with critically ill clinical patients´ mortality.

Patients and methods: This study analyzed the observational data prospectively collected over 8 months (2018) in an adult intensive care unit (ICU) in Brasilia, Brazil. All consecutive ICU-admitted clinical patients were included. Thyroxine (T4), free thyroxine (fT4), triiodothyronine (T3), free triiodothyronine (fT3), rT3, and thyroid-stimulating hormone (TSH) were collected within 48 hours of ICU admission. Patients with hypothyroidism or hyperthyroidism who were previously diagnosed were excluded.

Results: Of 353 included patients, age was 68.5 ± 19.0 years, sequential organ failure assessment (SOFA) score was 3.3 ± 2.9, and Acute Physiology and Chronic Health Evaluation II (APACHE II) was 17.1 ± 7.9. ICU mortality was 17.6% (n = 62). Non-survivor patients had a higher incidence of increased rT3 (69.3 vs 59.2%, p = 0.042), lower incidence of low T4 (4.8 vs 9.7%, p = 0.045), and increased age (75.2 ± 16.3 years vs 67.1 ± 19.3 years, p = 0.001), SOFA (3.0 ± 0.4 vs 2.8 ± 2.6, p <0.001), and APACHE II (23.5 ± 7.5 vs 15.7 ± 7.2, p <0.001). Alterations in other thyroid hormones did not show association with mortality. Increased rT3 [odds ratio (OR): 2.436; 95% confidence interval (CI): 1.023-5.800; p = 0.020] and APACHE II (OR: 1.083, 95% CI: 1.012-1.158; p = 0.044) were associated with ICU mortality in the multivariate analysis.

Conclusion: Increased rT3 was independently associated with increased ICU mortality. In contrast, other thyroid hormone alterations did not show an association with mortality. Determining rT3 levels may be a helpful test to identify an increased risk for ICU mortality in clinical patients.

The coronavirus disease-2019 (COVID-19) pandemic had overwhelmed the healthcare system and forced many patients to be treated at home with oxygen, antibiotics, and steroids, particularly during the second wave. There was increased misuse of antimicrobials in hospitals as well as unguarded self-prescription of these medications among the common people. We are likely to see an increase in the incidence of antimicrobial resistance (AMR), change in the susceptibility pattern of the organisms causing community-acquired infections, and an increase in opportunistic bacterial, tubercular, viral, and fungal infections.
