RESUMEN
Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome caused by macrophages and cytotoxic T cells with aberrant activation. The primary (genetic) form, which is caused by mutations that affect lymphocyte cytotoxicity and immune regulation, is most prevalent in children, whereas the secondary (acquired) form is prevalent in adults. Secondary HLH is commonly caused by infections or cancers, but it can also be caused by autoimmune disorders, in which case it is known as macrophage activation syndrome (MAS; or MAS-HLH). A 25-year-old female presented with a high-grade fever that lasted for two weeks. His laboratory results revealed pancytopenia, neutropenia, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia. Based on the clinical presentation and laboratory findings, a provisional diagnosis of HLH has been made. A HLH protocol was utilized to treat the patient. During the course of hospitalization, systemic lupus erythematosus (SLE) was identified as the underlying cause. She improved dramatically after receiving an immunosuppressive regimen of etoposide, cyclosporine, and dexamethasone according to HLH protocol-2004 with individualized modifications. The clinician should be aware that HLH may be the initial manifestation of underlying SLE. Early diagnosis and aggressive, individualized treatment are the key to improving outcomes.

BACKGROUND: This study aimed to explore the perception of doctors regarding telemedicine consultations and the level of patient satisfaction with the services received through teleconsultations. METHODS: This cross-sectional study was conducted on clinicians who provided teleconsultations and patients who received teleconsultations in an Apex healthcare institution in Western India. Semi-structured interview schedules were used to record the quantitative and qualitative information. Clinicians' perceptions and patients' satisfaction were assessed using two different 5-point Likert scales. Data were analyzed using SPSS v.23 using non-parametric tests (Kruskal Wallis and Mann-Whitney U). RESULTS: A total of 52 clinicians who delivered teleconsultations and 134 patients who received teleconsultations from those doctors were interviewed in this study. For 69% of doctors, telemedicine was feasible to implement, and for the rest, it was challenging. Doctors believe telemedicine is convenient for patients (77%) and prevents the transmission of infection (94.2%). Difficulty in clinical evaluation (73%), communication (55.7%), network connectivity (34%), diagnosis and investigations (32%), and patients' e-illiteracy (32%) were the most common challenges faced by clinicians. Patients' experiences were positive in terms of ease of registration (82.1%), audio quality (100%), freedom to discuss medicine (94.8%), and comprehension of the diagnoses (88.1%). Patients expressed satisfaction with the length of the teleconsultation (81.4%), the advice and care they received (78.4%), and the manner and communication of the clinicians (78.4%). CONCLUSIONS: Though there were some challenges in the implementation of telemedicine, the clinicians perceived it quite helpful. The majority of the patients were satisfied with teleconsultation services. Difficulty in registration, lack of communication, and a deep-rooted mindset of physical consultations were the primary concerns from the patient side.

Background: 16-66% of COVID-19 positive patients may have abdominal symptoms and findings in abdominal CT. The yield of abdominal CT scan in patients having abdominal complaints is not known. Objectives: The aim of this study was to explore the various abdominal imaging manifestations of COVID-19 and COVID-19 associated Mucormycosis (CAM) and to identify the relevant clinical and laboratory features associated with severity of the symptoms. Methods: A retrospective single centre observational study was performed at a tertiary care hospital in Northwest India. All consecutive patients who had COVID positive RT-PCR report and had undergone abdominal Computed Tomography scan from March 2020 to November 2021 for various abdominal complaints were included. Demographic data, CT images and reports and all relevant lab parameters were collected. Results: Out of 75 patients, positive abdominal findings were seen in 65 patients. Hepatobiliary findings were seen in 41.3% (31 of 75; OR=1.9) and bowel abnormalities were found in 37.3% (28 of 75; OR=2.1) of COVID-19 patients. 7 patients who had renal infarcts or bowel ischemia were found to have COVID-19 associated Mucormycosis on histopathology. Conclusion: Chest CT severity score was positively correlated with most of the abdominal manifestations in patients requiring ICU admission. Elevated D-dimer levels were significantly associated with abdominal symptoms.

As we delve into the intricacies of human disease, millions of people continue to be diagnosed as having what are labelled as pre-conditions or sub-clinical entities and may receive treatments designed to prevent further progression to clinical disease, but with debatable impact and consequences. Endocrinology is no different, with almost every organ system and associated diseases having subclinical entities. Although the expansion of these "grey" pre-conditions and their treatments come with a better understanding of pathophysiologic processes, they also entail financial costs and drug adverse-effects, and lack true prevention, thus refuting the very foundation of Medicine laid by Hippocrates "Primum non nocere" (Latin), i.e., do no harm. Subclinical hypothyroidism, prediabetes, osteopenia, and minimal autonomous cortisol excess are some of the endocrine pre-clinical conditions which do not require active pharmacological management in the vast majority. In fact, progression to clinical disease is seen in only a small minority with reversal to normality in most. Giving drugs also does not lead to true prevention by changing the course of future disease. The goal of the medical fraternity thus as a whole should be to bring this large chunk of humanity out of the hospitals towards leading a healthy lifestyle and away from the label of a medical disease condition.
RESUMEN
BACKGROUND AND PURPOSE: To compare Multiphase CT Angiography derived source images (mCTA-SI) in acute ischemic stroke (AIS) with CT Perfusion (CTP) derived automated color maps of cerebral blood flow (CBF) and cerebral blood volume (CBV) and to assess the comparability of mCTA-SI with CTP in the prediction of final radiological and clinical outcome. METHODS: This prospective single-centre observational study comprised of patients with AIS of the anterior circulation, presenting within 24 h and undergoing neuroimaging under stroke protocol with follow-up. Non-contrast computed tomography (NCCT), mCTA, and CTP were acquired with follow-up NCCT at 24 h and modified Rankin score (mRS) at 3 months. mCTA-SI and CTP color maps were scored by the ASPECTS (Alberta Stroke program early CT score) method and compared amongst each other and with the outcome. ROC (Receiver operating characteristic) curves were plotted considering mRS 0-2 and FIV≤ 28 ml as favourable clinical and radiological outcomes respectively. RESULTS: The study included 55 patients. The 1st and 2nd phase of mCTA-SI correlated significantly with CBF maps (r = 0.845, p < 0.01, r = 0.842, p < 0.01 respectively). 3rd phase of mCTA-SI correlated significantly with CBV maps (r = 0.904, p < 0.01). A favourable functional and radiological outcome was best predicted by the 1st (AUC 0.8, 95%CI 0.671-0.896) and 2nd ( AUC 0.895, 95% CI 0.783-0.962) phase of mCTA-SI respectively. CONCLUSIONS: The 1st and 2nd phases of mCTA-SI produces results congruent to CBF color maps and the 3rd phase of mCTA-SI simulate CBV color maps. In addition to predicting radiological and functional outcomes, mCTA can predict the salvageable and non-salvageable tissue in AIS and is non-inferior to CTP.

PURPOSE: Dehydroepiandrosterone sulfate (DHEAS) is observed to be decreased in sepsis and inflammatory conditions. In the present study, we assessed the levels of DHEAS and cortisol and the DHEAS/cortisol ratio and their association with inflammatory markers in patients with COVID-19. METHODS: The study recruited 76 RT-PCR-positive COVID-19-positive patients and 79 healthy controls. The blood samples were collected and were analyzed for cortisol and DHEAS. RESULTS: We observed decreased levels of DHEAS and DHEAS/cortisol ratio and increased levels of cortisol in cases when compared with controls. DHEAS and DHEAS/cortisol ratio showed a decreasing trend with the increase in disease severity. CONCLUSION: The present study is the first of its kind comparing DHEAS levels and DHEAS/cortisol ratio in COVID-19 patients and control subjects. DHEAS, with its inhibitory effect on IL6 and activation of Tregs, may play a crucial role in immune defense mechanisms against COVID-19.

Objectives: The current COVID-19 pandemic has created a huge impact across the globe. Recent literature has reported the occurrence of varied oral lesions in COVID-19 patients in the form of sporadic case reports. This analytical cross-sectional study was carried out to gauge and understand the pattern of oral lesions in qualitative RT-PCR-confirmed COVID-19 patients. Methods: A cross-sectional study involves a total of 500 qualitative RT-PCR confirmed, hospitalized COVID-19 patients who were meticulously scanned for any hard and soft tissue lesions developing concomitantly with the disease occurrence. Results: This study included a total of 367 (73.4%) males and 133 (26.6%) female patients with a mean age of 53.46 ± 17.50 years. Almost 51.2% of patients presented with gustatory disturbance, 28% with xerostomia and 15.4% of patients were found to have oral findings like erythema, ulcers, depapillation of tongue. There was a statistically significant correlation between oral manifestations and disease severity (p ≤ 0.001). Conclusion: COVID-19 is found to effect oral health with greater probability in patients with severe diseases (SARI) which may be due to disease itself, immune response and lack of motivation for personal hygiene measures.

RESUMEN
INTRODUCTION: Health care workers (HCWs) are directly involved in processes linked with diagnosis, management, and assistance of coronavirus disease-19 (COVID-19) patients which could have direct implications on their physical and emotional health. Emotional aspects of working in an infectious pandemic situation is often neglected in favour of the more obvious physical ramifications. This single point assessment study aimed to explore the factors related to stress, anxiety and depression among HCWs consequent to working in a pandemic. MATERIAL AND METHODS: This was a cross-sectional study involving healthcare workers who were working in COVID-19 inpatient ward, COVID-19 screening area, suspect ward, suspect intensive care unit (ICU) and COVID-19 ICU across four hospitals in India. A web-based survey questionnaire was designed to elicit responses to daily challenges faced by HCWs. The questionnaire was regressed using machine-learning algorithm (Cat Boost) against the standardized Depression, Anxiety and Stress Scale - 21 (DASS 21) which was used to quantify emotional distress experienced by them. RESULTS: A total of 156 participants were included in this study. As per DASS-21 scoring, severe stress was seen in â¼17% of respondents. We could achieve an R² of 0.28 using our machine-learning model. The major factors responsible for stress were decreased time available for personal needs, increasing age, being posted out of core area of expertise, setting of COVID-19 care, increasing duty hours, increasing duty days, marital status and being a resident physician. CONCLUSIONS: Factors elicited in this study that are associated with stress in HCWs need to be addressed to provide wholesome emotional support to HCWs battling the pandemic. Targeted interventions may result in increased emotional resilience of the health-care system.
RESUMEN
BACKGROUND: Studies have linked vitamin D to risk factors for cardiovascular disease. Obesity is a potential confounder in these studies. This study examined the relationship of 25 (OH) cholecalciferol (25[OH] D3) with insulin resistance, blood glucose, and lipid profile in lean male adults. METHOD: We enrolled two hundred and thirty four military recruits before beginning of military training. Demographic and anthropometric data were collected from them. The participants underwent body mass composition analysis by dual energy X ray absorptiometry. Fasting samples were collected for measurement of blood glucose, lipid profile, 25(OH) D3, serum parathormone (PTH) and insulin. RESULTS: Vitamin D deficiency and insufficiency was found in 47.7% (107/224) and 31.6% (71/224) of participants, respectively. Using Pearson's correlation coefficient 25(OH) cholecalciferol and fasting blood glucose (FBG) were inversely correlated (p = 0.023). However, similar relation was not found between 25(OH) D3 and total cholesterol, triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, homeostatic model assessment of insulin resistance and levels of PTH. On body composition analysis, there was no correlation of 25(OH) cholecalciferol with body mass index or fat mass index. CONCLUSION: This study showed that in lean young male population, 25(OH) cholecalciferol and FBG are inversely correlated but no association of 25(OH) D3 with other cardiometabolic risk factors could be demonstrated.
RESUMEN
BACKGROUND: Uncontrolled increase in Reactive Oxygen Species (ROS) leads to the release of free radicals. Additionally, when antioxidants go below a certain level, major molecules of our system such as DNA, proteins, and many other macromolecules get damaged, leading to cancer, heart diseases, and metabolic syndromes like diabetes. Therefore, we in our study focused on newly diagnosed Type 2 Diabetes Mellitus (T2DM) patients and tried to evaluate the expression of antioxidant enzyme encoding genes; Superoxide Dismutase 1(SOD1) and Superoxide Dismutase 2 (SOD2) and DNA repair genes; X-ray repair cross-complementing 1(XRCC1) and 8-oxoguanine DNA glycosylase 1 (OGG1) in them. METHODS: Expression analysis was performed by RT-PCR on 60 subjects (30 T2DM cases and 30 non-diabetic controls). The level of the SOD enzyme was also estimated in a serum sample by the colorimetric method. Biochemical parameters such as fasting plasma glucose (FBG), glycated haemoglobin (HbA1c), high sensitivity C-reactive protein (hsCRP), and lipid profile were estimated in an auto analyzer. Receiver operating characteristic (ROC) curve analysis was done, the area under the curve for mRNA expression and enzyme level was calculated to determine their potential as markers in newly diagnosed T2DM. RESULTS: Down-regulation of both SOD1 (0.43 fold, p=0.02) and SOD2(0.41 fold, p=0.13) and up-regulation of both XRCC1(1.15 fold, p>0.05) and OGG1(1.49 fold, p>0.05) was observed in patients with T2DM. We also observed a significant decrease (p=0.02) in SOD enzyme levels in diabetic cases than in controls (599.8 ± 178.9 and 691.3 ±127.3). CONCLUSIONS: We report that antioxidant repair genes are downregulated and DNA repair genes are upregulated in newly diagnosed T2DM patients. SOD levels and SOD1 gene expression can serve as informative biomarkers for identifying T2DM patients.
RESUMEN
OBJECTIVE: This study aimed to use chest-X-ray (CXR)-based scores along with total leukocyte count (TLC) and neutrophil-to-lymphocyte ratio (NLR) in the prediction of coronavirus disease 2019 (COVID-19) in patients presenting with clinical features of severe acute respiratory illness (SARI). MATERIAL AND METHODS: This is a retrospective study involving all patients who presented with clinical features of SARI and who had undergone bedside chest X-ray (CXR), hemograms with TLC, NLR, and reverse transcriptase-polymerase chain reaction (RT-PCR) at our institute from May 1 to June 30, 2020. RESULTS: Of 204 patients, 115 tested RT-PCR-positive and 89 tested negative. The patients who presented with SARI, using CXR-based score of 4 or more, TLC of less than 8,700 cells/µL, and NLR of <7 had a statistically significant area under the curve (p<0.001) for diagnosing COVID-19. The sensitivity and specificity of the CXR score was 80.8% and 73.0%, of TLC was 70.1% and 74.7%, and of NLR was 70.1% and 59.0%, respectively, in diagnosing COVID-19 alone. The specificity further increased to 90.4% when we used the CXR score with NLR and to 92.8% when we used the CXR score with TLC. The post-test odds ("rule in" disease) of a positive test for having the disease were 3, 2.77, and 1.71 times with the use of either CXR score, TLC, or NLR criteria, respectively; whereas, combined use of CXR score and NLR increased the post-test odds by 5.53 times, and combination of CXR score with TLC increased the post-test odds by 7.5 times. CONCLUSION: CXR score with TLC and NLR can predict COVID-19 infection among those who presented with features of SARI. This may help in the early isolation of the patient until the RT-PCR report becomes available.
RESUMEN
AIM: This prospective observational study evaluated the role of infrared (IR) dermal thermometry in the management of diabetic foot ulcers. METHODS: Thirty participants with unilateral neuropathic diabetic foot ulcers of University of Texas grade 1 or 2 (stage A) were followed up monthly for 1 year. At each visit, skin temperatures were measured with an IR dermal thermometer at corresponding sites on both feet, using the contralateral feet without ulcers as controls. RESULTS: Average temperature and ulcer temperature in affected feet were significantly higher than in unaffected feet, with a mean difference of 1.2 °C [95% confidence interval (CI) 0.7 to 1.7] and 3.1 °C (95% CI 2.3 to 3.9), respectively. Although the gradient between average temperature of affected foot and that of unaffected foot normalized (mean difference 0.2 °C, 95% CI -0.2 to 0.7) at healing, the temperature gradient between the ulcer and a corresponding site on the unaffected foot decreased but did not normalize (mean difference 2.1 °C, 95% CI 1.2 to 3.1) even at healing, as documented by skin closure, and persisted for up to 1 month after skin closure. A gradient of ≥1 °C between average temperature of affected foot and that of unaffected foot at initial presentation or at any time during ulcer healing was found to predict impaired healing and should alert clinicians to ulcers requiring more attention. An incremental trend in temperature gradient (median difference 2.2 °C; range 0.1-6.3 °C) at a site on the foot was predictive of a recurrent ulcer involving the same site. CONCLUSIONS: IR dermal thermometry may have a role in predicting diabetic foot ulcer healing, in determining the completeness of healing and in guiding the duration of offloading. Serial monitoring of the temperature gradient may predict the development of recurrent diabetic foot ulcers.

Vegetable milks are fast gaining attention on the global scale as the possible alternatives due to concerns associated with milk consumption. In particular, issues varying from allergenic constituents and lactose intolerance to social and religious beliefs among consumers have induced an increase in the market demand for vegetable milks. Their concomitant nutritional and bioactive components appraise them of the suitable profile for the food-based carriage and delivery of probiotics. More so, the presence of prebiotics in their natural configuration makes them serviceable for the assurance of the needed probiotic viability, subsequent to their exposure to digestive conditions. On another note, their availability, ease of processing, and cost-effectiveness have been established as other possible rationales behind their adoption. This chapter comprehensively delineates the probiotic and prebiotic food-usage of vegetable milks. Captions related with consumer concerns, processing operations, nutritional and prebiotic constitutions, metabolic interactions during probiotic fermentation, and associated health benefits of vegetable milks are discoursed.

BACKGROUND: Duration of persistence of SARS-CoV-2 in the upper respiratory tract of infected individuals has important clinical and epidemiological implications. AIM: We aimed to establish the duration and risk factors for persistence of SARS-CoV-2 in the upper respiratory tract of asymptomatic infected individuals. METHODS: Data of repeat rRT-PCR (real-time reverse transcription-polymerase chain reaction) test done for SARS-CoV-2 infected individuals at our institute at Jodhpur, India were analysed from 19 March to 21 May 2020. Duration of virus persistence was estimated with parametric regression models based on weibull, log-normal, log-logistic, gamma and generalized gamma distributions. Factors associated with prolonged viral persistence were analysed with the best-fitting model. RESULTS: Fifty-one SARS-CoV-2 infected individuals with repeat rRT-PCR test were identified with 44 asymptomatics. The asymptomatic individuals had median virus persistence duration of 8.87 days (95% CI: 7.65-10.27) and 95 percentile duration of 20.70 days (95% CI: 16.08-28.20). The overall median virus persistence including both symptomatic and asymptomatic individuals was found to be 9.18 days (95% CI: 8.04-10.48). Around one-fourth asymptomatics (10/44) demonstrated SARS-CoV-2 persistence beyond 2 weeks. Age <60 years and local transmission were found to be significantly associated with longer virus persistence among asymptomatic individuals on univariate regression but not in multivariate analysis. CONCLUSION: Recommended home isolation duration for SARS-CoV-2 infected individuals in India should be extended from 17 days to at least 3 weeks. Prolonged persistence of SARS-CoV-2 in a considerable proportion of asymptomatic individuals merits attention with regard to ensuring universal infection prevention precautions irrespective of symptomatic status.

BACKGROUND AND AIMS: Fasting has a long tradition in most cultures and has many health benefits. Most of the studies are from daytime fasting or intermittent fasting. There is paucity of data from complete fasting (no food and fruits, water only). This prospective study is conducted with aims to study impact of complete fasting on clinical and biochemical parameters. METHODS: One hundred ten participants of either gender who voluntarily fasted (3-30 days) were included and underwent clinical and biochemical examination before and after fasting. RESULTS: A total of 110 healthy volunteers (M: 27, F: 83) with mean age 51 ± 16 years (range 18-86) and body mass index 27.1 ± 4.9 kg/m2 (16.1-45.2) were studied. They had undergone fast for varying duration between 3-30 days (short fast: 3-7 days = 72; prolong fast: >7 days = 38). There were significant decrease in weight (66.8 ± 11.0 to 64.7 ± 11.1 kg, P < 0.0001), BMI (27.1 ± 4.9 to 26.2 ± 4.9 kg/m2, P < 0.0001), systolic blood pressure (130 ± 17 to 128 ± 15 mmHg, P = 0.012), serum globulin (3.10 ± 0.42 to 3.01 ± 0.41 mg/dl, P = 0.024), and serum high density lipoprotein (48.3 ± 12.2 to 45.7 ± 12.6 mg/dl, P < 0.0001) post fasting. However, significant increase was observed in pulse rate (81 ± 10 to 83 ± 11 beat/min, P = 0.001), fasting plasma glucose (102.9 ± 35.0 to 132.0 ± 42.0 mg/dl, P < 0.0001), serum triglycerides (137.6 ± 68.3 to 149.0 ± 67.1 mg/dl, P = 0.031), very low density lipoprotein (22.0 ± 10.5 to 24.2 ± 11.1 mg/dl, P = 0.010), and serum cortisol levels (13.5 ± 5.9 to 17.2 ± 6.3 µg/dl, P < 0.0001). These changes were more pronounced with prolong fasting, but were not affected by gender. CONCLUSIONS: Fasting results in improvement in anthropometric, physical and biochemical parameters related to physical health. It can be recommended as a mean for improving quality of life.
RESUMEN
BACKGROUND: Vitamin D deficiency (VDD) is ubiquitous in the Indian subcontinent. VDD has been shown to impair muscle functions. However, the association of VDD with cardiorespiratory endurance is uncertain. Hence, we enrolled and supplemented vitamin D in military recruits with VDD with an aim to evaluate effect of supplementation on cardiorespiratory endurance and muscle strength. METHOD: We enrolled 90 military recruits with VDD and randomly allotted them to two groups equally. The group I received cholecalciferol granules 60,000 IU every fortnight for twelve weeks (cases), and the group II was observed as control. Muscle strength and cardiorespiratory endurance was assessed with a battery of tests (standing broad jump, bent arm hang test, 20 m shuttle run) at baseline and repeated at the end of training (nineteen weeks). Blood samples were collected for measurement of serum 25(OH)D and parathyroid hormone. RESULTS: In Group I and Group II, there was significant increase in 25(OH) D levels (25.8 ± 7.1 and 17.3 ± 3.5 ng/ml, respectively), and in VO2 max (9.8 ± 8.8 and 12.7 ± 8.6 ml/kg/min, respectively) compared with the baseline values. However, no significant change was observed in muscle strength after supplementation. There was no difference between the groups in VO2 max and muscle strength at baseline and at the end of training. CONCLUSION: Vitamin D supplementation did not improve muscle strength and cardiorespiratory endurance in military recruits with VDD. A significant rise in 25(OH) D was observed even in those not supplemented with vitamin D.
