RESUMO

ABSTRACT Echinococcosis is a parasitic disease caused by infection with tiny tapeworms of the genus Echinococcus. Echinococcosis is classified as either cystic echinococcosis or alveolar echinococcosis. The common form is a zoonosis from goats and sheep that tends to cause liver lesions. The larval stage of Echinococcus multilocularis causes alveolar echinococcosis/alveolar hydatid disease. It is a zoonosis with field mice and tundra voles as intermediate and wild carnivores like foxes and wolves as definitive hosts. This zoonosis is highly uncommon compared to the other form known as cystic echinococcosis but poses a great human threat if untreated. We report the case of a young man who was working in the Kashmir Valley, North India, and presented with jaundice and right upper quadrant abdominal pain. Computed tomography revealed a large solid-cystic intrahepatic lesion measuring 125x118x123 mm, suggestive of a malignant tumor with central necrosis. A liver biopsy showed necrosis with PAS-positive membranes morphologically consistent with echinococcosis. Alveolar echinococcosis can present as a solid-cystic mass in the liver and can simulate metastatic malignancy.

RESUMO

Background: Given the improvement in life expectancy of people living with HIV (PLWH) in sub-Saharan Africa, the risk of asymptomatic HIV-associated neurocognitive disorder (HAND) has increased. The study objectives were to investigate the prevalence of HAND and associated factors among treatment experienced adults in Ethiopia. Methods: A single-center observational cross-sectional study was conducted between December 2019 and June2020 to investigate HAND. International HIV dementia scale (IHDS) was used to screen for the disorder. Both descriptive and analytical statistics were used to analyze the data. Results: Total of 324 PLWH (63% females) who were on combination antiretroviral therapy for median of 144months (IQR: 108-168) were investigated. The mean age was 42.5 years (1SD=12.2). The prevalence of HAND was 75.3% and the difference was significantly more in those above 40 years of age (65.8% vs. 80.7%, p=0.003). Age is the only risk factor identified with multivariable logistic regression analysis. A linear decrement in the total score of cognitive performance was observed as the patient's age increase; age was responsible for 9.4% variation observed in IHDS score (r= -0.31, R2=0.094, p<0.0001). Although statistically not-significant, the trend for cardio-metabolic and behavioral risk factors (hypertension, diabetes mellitus, dyslipidemia, smoking, alcohol and khat use) was higher in the group diagnosed with HAND. Conclusion: The occurrence of neurocognitive impairment was more pronounced in individuals aged 40 years and above who were HIV positive, compared to those below 40 years. Age was found to be an independent predictor of HAND. Cardiovascular and behavioral risk factors were observed more among patients with HAND compared to no-HAND

RESUMO

Purpose: To study the prevalence of pseudoexfoliation syndrome (PEX) in diabetics with senile cataracts and compare it to the prevalence in nondiabetic control group. Methods: Two hundred and fifty diabetics and 250 nondiabetics (age and sex matched) were evaluated for PEX deposition. Results: Chi?squared test was employed, and a P value < 0.05 was considered significant. In the PEX group, most patients belonged to the age group of 60–70 years (55.17%). Out of 18 patients with PEX, 11 (61.1%) showed bilaterality. There was a higher frequency of raised intraocular pressure (IOP; >20 mmHg) in PEX eyes (10.3%) than in the non?PEX eyes (5.9%). The PEX group had a higher number of eyes with cup?to?disc ratio (CDR) >0.6 (11.12%) than the non?PEX group (4.32%). Nuclear cataracts were more frequent in PEX eyes than non?PEX eyes, whereas PSC and mature cataracts were more prevalent in the non?PEX group. Most eyes had PEX deposition on the anterior lens capsule and pupillary margin. Of the 500 study eyes corresponding to the diabetic group, 418 had cataracts (rest pseudophakic), of which 28 had pseudoexfoliation, accounting for 6.7% of the total. In the nondiabetic control group comprising 500 eyes, 430 had senile cataracts (rest pseudophakic), of which 105 had PEX deposition, accounting for 24.4% of the total. Conclusion: According to our findings, diabetics have a lower prevalence of PEX than nondiabetics. Few such studies have been conducted so far, and none have been conducted in the Indian population.

RESUMO

Objective:To provide the regional pediatric cancer (age-group 0-14 years) burden and pattern in India utilizing published data of population-based cancer registries established under the National Cancer Registry Programme and Tata Memorial Centre, Mumbai. Methods:Based on the geographic locations, the population-based cancer registries were categorized into six regions. The age-specific incidence rate was calculated using the number of pediatric cancer cases and population in the respective age-group. Age-standardized incidence rate per million and 95% CI were calculated.Results: In India, 2% of all cases were pediatric cancer. The agestandardized incidence rate (95% CI) for boys and girls is 95.1 (94.3-95.9) and 65.5 (64.8-66.2) per million population, respectively. Registries from northern India reported the highest rate; while the lowest rate was in northeastern India. Conclusion:There is a need to establish pediatric cancer registries in different regions of India to know the accurate pediatric cancer burden.

RESUMO

Purpose: Ripasudil is a class of drug which alters the trabecular meshwork to increase the aqueous outflow and has been shown to be effective in pseudoexfoliative glaucoma (PXF G). This study aimed at assessing the efficacy and safety profile of ripasudil as an adjunct treatment in patients with PXF G at maximal tolerated antiglaucoma medications. Methods: In this prospective, interventional study, 40 patients with PXF G were enrolled between May 2021 and Jan 2022. Ripasudil 0.4% was started as an adjunctive drug to the ongoing antiglaucoma medications. On follow?up visits at 1, 3, and 6 months, the visual acuity, intraocular pressure (IOP), anterior segment, and fundus findings were evaluated. The premedication and postmedication IOP values were compared by paired t?test, and a P?value <0.05 was considered statistically significant. Results: Average age at recruitment was 60.02 ± 8.74 years. Baseline premedication IOP was 25.375 ± 3.276 mmHg. IOP reduction at 6 months was found to be statistically significant in all patients, with the maximal response being 24.13%. Also, 87.5% (35/40) of patients reached target IOP or even lower IOP at the end of study. There was no statistically significant association between the PXF grade and IOP. However, the grade of inferior iridocorneal angle pigmentation was found to be higher in eyes with elevated IOP (P < 0.05). Only three patients developed conjunctival hyperemia as an adverse reaction, which was mild and transient. Conclusion: Ripasudil showed additional IOP?lowering effect with other antiglaucoma medications and exhibited no significant side effects

RESUMO

COVID-19 infection has been linked to various ocular complications and complaints, but not to refractive errors. In this case report, we present ethnically diverse patients who reported asthenopic symptoms shortly after recovering from COVID-19 infection. The hyperopic shift in the refractive error, post-COVID could indicate the ciliary body muscle’s inability to sustain accommodation, resulting in asthenopia. Hence, refractive errors should also be considered as a post-COVID complication, even if the magnitude is small, especially when patients have a headache and other asthenopic symptoms. Performing dynamic retinoscopy and cycloplegic refraction will also aid in the better management of these patients

RESUMO

Background & objectives: Multidrug-resistant (MDR) Acinetobacter baumannii is a serious threat for human health worldwide. The studies on agents targeting A. baumannii are imperative due to identified A. baumannii co-infections in COVID-19. Bacteriophages are promising antibacterial agents against drug-resistant bacteria. This study intended to isolate bacteriophages against MDR A. baumannii from the water of river Ganga, to be used potentially as therapeutic and disinfectant particles. Methods: Acinetobacter phages were isolated from the Ganga water collected from Kanpur and further tested on 50 MDR A. baumannii isolates to determine host range. The phages were morphologically characterized by transmission electron microscopy. The disinfectant property of the isolated phages was tested by spraying of bacteriophage cocktail on MDR A. baumannii contaminated plastic surface, analyzed by colony-forming unit (CFU) and bioluminescence assay (adenosine triphosphate monitoring). Results: A total of seven bacteriophages were isolated against MDR A. baumannii. The bacteriophages lysed three MDR A. baumannii isolates out of 50 tested, showing narrow host range. Electron microscopy revealed hexagonal heads and long tails of bacteriophages, belonging to order Caudovirales. The bacteriophage cocktail reduced the MDR A. baumannii load efficiently on plastic surface, evidenced by reduction in CFUs and bioluminescence. Interpretation & conclusions: The findings of this study suggest that the isolated bacteriophages are potential lytic agents for MDR A. baumannii clinical isolates, and may be used as potential therapeutic agents as well as disinfectant to combat MDR A. baumannii with due consideration to phage host specificity, with further characterization.n

RESUMO

Background: During the present surge of COVID-19 positive cases, concurrent multifold increase in the incidence of mucormycosis cases has resulted into significant morbidity and mortality. We retrospectively evaluated the clinicopathological features along with microbiological examination findings in histologically diagnosed cases of rhino-orbital mucormycosis. Material and Methods: All the H and E and special stained slides of included mucormycosis cases were retrieved from the records and were evaluated with microbiological findings including screening KOH mount examination and culture results. Results: Out of 16 cases with available details, 10 cases had the previous history of diabetes mellitus. The most frequent single site of involvement was maxillary sinus (7/25) followed by nasal cavity, orbit, ethmoid and sphenoid sinuses. While comparing the histological diagnosis with KOH mount findings and culture results, 15 cases revealed consistent results. Conclusion: A high clinical suspicion, monitoring, early diagnosis, and timely management can improve the morbidity and mortality of this life-threatening complication.

RESUMO

Introduction: Cancer stem cells (CSC) within the tumors play a central role in tumorigenesis. It is, thus, of utmost importance to identify these cells to develop effective cancer therapy. Triple-Negative Breast Cancer (TNBC) is an aggressive molecular subtype of breast cancer associated with poor patient outcomes. The role of CD44 immunohistochemistry (IHC) as a putative CSC in breast carcinomas, particularly of the TNBC-subtype is ambiguous, with equivocal results. Aims and Objectives: The present study aims to assess the role of CSC in breast carcinoma by immunohistochemical analysis of CD44 expression in TNBC. The association of TNBC expressing CSC with histological grade as well as with angiogenesis (using CD34 IHC) has been studied. Materials and Methods: Biopsy samples from 58 patients with infiltrating ductal carcinoma, NST were studied. The histology of the tumor was sub-classified into grades 1–3. Based on immunohistochemical analysis (ER, PR, HER2/Neu), the cases were divided into TNBC and NTNBC groups. The tissue sections were also subjected to analysis for CD44 to identify the CSC-phenotype and CD34 to evaluate angiogenesis, to determine the microvascular density (MVD). Results: Out of the 58 cases in the study, 28 were TNBC and 30 were NTNBC. CSC phenotype (CD44 positive) was expressed significantly higher in the TNBC (78%) versus the NTNBC (53%) (p-value 0.043). The MVD estimated using CD34 IHC was lower in the TNBC group in our study, though the difference was not statistically significant. A larger proportion of cases in TNBC showed a higher histological grade (35%) in comparison to NTNBC (27%). However, statistically, it was not significant. Conclusion: Our study demonstrated that CD44 as a CSC marker is seen significantly more in the TNBC category of invasive ductal carcinomas. Further large-scale studies, to confirm these findings, will be of potential therapeutic and prognostic value.

RESUMO

Background: The prevalence of skin diseases has increased over the last few decades, and they contribute to a significant burden on health-care systems across the world. Aims/Objective: This report looks at the burden of skin and subcutaneous diseases in terms of years lived with disability and age-standardised years lived with disability in India using the Global Burden of Disease Study results from 2017. Methods: Data were obtained from the Global Burden of Disease online interactive tool. Updated estimates of the world’s health for 359 diseases and injuries and 84 risk factors from 1990 to 2017 are available in this interactive tool. Results: Years lived with disability due to skin and subcutaneous diseases accounted for 4.02% of the total years lived with disability in India in 2017. There was an increase of 53.7% in all age standardised years lived with disability for all the skin and subcutaneous diseases from 1990 to 2017. Among skin and subcutaneous diseases, dermatitis contributed maximum years lived with disability (1.40 million; 95% uncertainty interval, 0.82–2.21) in 2017, followed by urticaria (1.02 million; 95% uncertainty interval, 0.06–1.44) with percentage increases of 48.9% and 45.7% respectively. Conclusion: The burden due to infectious skin diseases (e.g., scabies, fungal skin disease and bacterial skin disease) and non-infectious diseases (e.g., dermatitis, urticaria and psoriasis) has increased over the past three decades, however the age-standardised years lived with disability for leprosy, scabies, fungal infections, sexually transmitted infections and non-melanoma skin cancer (basal cell carcinoma) has decreased. The high burden of skin and subcutaneous diseases demand that they be given due importance in the national programmes and health policy of India.

RESUMO

Background: India has the highest burden of tuberculosis in the world. It is experiencing an increasing burden of noncommunicable diseases, thereby facing a dual disease burden. Recent evidence shows an association between TB and noncommunicable diseases like diabetes, CVD and chronic respiratory infections. Aims and Objectives: To assess the feasibility of screening for NCDs and risk factors for NCDs among patients with TB in DOTS centers of a medical college in Delhi and ascertain challenges for the same among providers and patients. Methodology: It was a mixed-methods study with a quantitative component (cross-sectional study using questionnaires, anthropometric measurements and records review) and a qualitative component (descriptive study using interview data). Results: Among the 139 patients screened, ten new cases of hypertension and six new patients were diagnosed with DM. Outof- pocket expenditure for tests was a concern of the patients. Health care providers found the screening tool easy to use but were apprehensive about increased workload Conclusion: The study provide useful visions for incorporating NCDs into routine TB care through DOTS centers under RNTCP/NTEP.

RESUMO

Objective: Snake bite is an emergency in tropical and subtropical countries. It is a neglected disease and is most commonly seen in rural setups, where people are ignorant about the venomous snake bites. It results in increased mortality and morbidity because precious time is wasted, either in consulting traditional healers or waiting for the development of signs and symptoms of envenomation. Then only the patient is shifted to a health center. Here we studied the clinical profile, management, and outcome of snake bite patients. Materials and methods: This study was done by retrieving the records of patients with snake bites admitted to the Department of Medicine, Indira Gandhi Medical College & Hospital, Shimla, from 1st January 2017 through December 2019. The recorded data was entered in a precoded performa, and analysis was done with respect to various variables. Result: We evaluated the records of 190 patients. The incidence of the bite was higher among females, 62.1% (n = 118). The commonest age group involved was 21–50 years, 70.1% (n = 34). In 55.8% (n = 106), the site of the bite was the upper limb. The daytime bite was present in 54.7% (n = 106). The maximum incidence of snake bites was found during the rainy season, 81.5% (n = 155). 28.4% (n = 54) of patients presented within 6 hours of the bite. Coagulopathy [whole blood clotting test (WBCT) of >20 minutes] and neurotoxicity were seen in 77.9 and 7.9% of patients, respectively. Anti-snake venom (ASV) was given to 87.8% (n = 167) of patients. In 80% (n = 152) of the cases, hospital stay was up to 3 days. Mortality was seen in only two (1.05%) cases. Conclusion: There is a need to create awareness among the community, particularly in rural areas, about snake bite envenomation and early transportation of victims to the nearest health center. Training of health professionals is also needed to manage cases of snake bites efficiently and judiciously, thereby reducing morbidity and morbidity.

RESUMO

Background: The data on incidence of recovered Left Ventricular Ejection Fraction (LVEF) and outcome in patients with non ischemic systolic heart failure is limited. We report the incidence, determinants and mortality in patients with recovered LVEF. Methods: The 369 patients with HFrEF with LVEF of less than 40% of non ischemic etiology with available follow up echocardiography study at one year were enrolled. The baseline data of clinical characteristics and treatment was recorded prospectively and were followed up annually for mean of 3.6 years (range 2 to 5 years) to record all cause death and LVEF measured echocardiographically. The recovered, partially recovered and no recovery of LVEF was defined based on increase in LVEF to 50% and more, 41% to 49% and to persistently depressed LVEF to 40% or lower respectively. Results: The LVEF recovered in 36.5%% of the cohort at 5 years. The rate of recovery of LVEF was slower in patients with no recovery of LVEF at one year compared to cohort with partially recovered LVEF (18% vs.53%) at five year. The Baseline LVEF was significantly associated with recovered LVEF, odd ratio (95% C.I.) 1.09(1.04, 1.14). The cumulative mortality at five years was significantly lower in cohort with recovered LVEF (18.1% vs. 57.1%). Conclusions: One third of the patients had recovered LVEF and was significantly associated with baseline LVEF and lower mortality rate.

RESUMO

Introduction: During menopause, women experience various psychological or physical changes which need adequate attention. Moreover, women don’t seek help for these problems due to their hesitancy, lack of awareness, socio-cultural, financial constraints or as they feel this is a natural-phenomenon. The study aims to explore the postmenopausal experiences faced by women during menopause and to elicit the constraints faced by them in seeking health-care services. Methodology: This was a qualitative study with phenomenological approach conducted among post-menopausal women (≥45 years) from Oct 2022-Jan 2023 with the help of In-Depth-Interview guide in four villages of Bhatar Block, Purba-Bardhaman District. Considering the availability of the study participants, they were selected purposively from the list prepared by ASHA of each village and recruitment done till the point of data-saturation. Inductive thematic-analysis was used to identify codes and themes. Results: During menopause, women experienced physical and psychological changes in the body, changes in social life and for these changes they had to adjust to cope-up. They felt various needs like empathy from hus-bands, children, peers. On the other hand, they did not seek help from health-care services due to their knowledge gap, dissatisfaction from previous-visit, cost-issue and unavailability of resources in health-care delivery system. Conclusion: Majority of the post-menopausal women faced various problems associated with menopause, but very few had sought help. So, health care providers have an important role to generate awareness among post-menopausal women regarding physical and mental changes during this phase.

RESUMO

Background: Ocular morbidity with an early onset can have a significant impact on the long-term development of an individual. Hence, careful assessment of visual functions early on is very important. However, testing infants always poses a challenge. Standard tools to assess infants’ visual acuity, ocular motility, and so on rely on the clinician’s quick subjective judgments of an infant’s looking behavior. Eye movements are usually observed from head rotations or spontaneous eye movements in infants. Judging eye movements in the presence of strabismus is even more challenging. Purpose: This video shows a 4-month-old infant’s viewing behavior captured during a visual field screening study. The recorded video aided in the examination of this infant that was referred to a tertiary eye care clinic. The additional information captured through the perimeter testing is discussed. Synopsis: The Pediatric Perimeter device was developed to address visual field extent and gaze reaction time assessment in the pediatric population. As a part of a large-scale screening study, infants’ visual fields were tested. During this screening, a 4-month-old infant presented with a ptosis in the left eye. The infant was consistently missing the light stimuli presented in the left upper quadrant in the binocular visual field testing. The infant was referred to a tertiary eye care center to a pediatric ophthalmologist for further examination. During clinical examination, the infant was suspected to either have congenital ptosis or monocular elevation deficit. But the diagnosis of the eye condition was unsure owing to the poor cooperation of the infant. With the aid of Pediatric Perimeter, the ocular motility was consistent with limitation of elevation in abduction, indicating a possible monocular elevation deficit with congenital ptosis. The infant was also noted to have Marcus Gunn jaw-winking phenomenon. The parents were assured and asked for a review in 3 months. In the subsequent follow-up, the Pediatric Perimeter testing was performed, and the recording showed a full extraocular motility in both eyes. Hence, the diagnosis was changed to only congenital ptosis. The probable explanation for missing the target in the left upper quadrant in the first visit is postulated further. The left upper quadrant is the superotemporal visual field of the left eye and the superonasal visual field of the right eye. As the left eye had ptosis, the superotemporal visual field could have been obstructed and hence the stimuli missed. The normative extent for the nasal and superior visual field is just about 30° for a 4-month-old infant. Hence, the right eye also perhaps missed the stimuli in its superonasal visual field extent. This video highlights the utility of the Pediatric Perimeter device in providing a magnified view of the infant’s face along with greater visibility of ocular features from the infrared video imaging. This can potentially help the clinician to easily observe different ocular/facial abnormalities such as extraocular motility disorders, lid functions, and in identifying unequal pupil size, media opacities, and nystagmus. Highlights: The presence of congenital ptosis in younger infants might predispose as superior visual field defect and could also masquerade as a limitation in elevation.

RESUMO

Purpose: To determine the pattern of pediatric ocular morbidities in western India. Methods: This was a retrospective longitudinal study that included all consecutive children aged ?15 years who presented to the outpatient department of a tertiary eye center for the first time. Patient demographics, best?corrected visual acuity (BCVA), and ocular examination data were compiled. Subgroup analysis was also performed based on age group (years): ?5, 5–10, and >10–15. Results: A total of 11,126 eyes of 5563 children were included in the study. The mean age of the study population was 5.15 (±3.32) years with males (57.07%) being predominant. Approximately half of the patients (50.19%) were under the age of 5 years, followed by those aged 5–10 years (45.1%) and >10–15 years (4.71%). Among the study eyes, the BCVA was ?20/60 in 58.57%, indeterminable in 35.16%, and <20/60 in 6.71%. The commonest ocular morbidity noted was refractive error (28.97%) followed by allergic conjunctivitis (7.64%) and strabismus (4.95%) in the total study cohort and also after age stratification. Conclusion: Refractive error, allergic conjunctivitis, and strabismus are the major causes of ocular morbidity in pediatric eyes at a tertiary care center. Planning screening programs at the regional and national levels is crucial to decreasing the burden of eye disorders. These programs also need to have a suitable referral mechanism established and be smoothly connected to primary and secondary health?care centers. This will help to assure quality eye care delivery, while also reducing the strain of overworked tertiary centers.

RESUMO

Health care–associated infections (HAI) directly influence the survival of children in pediatric intensive care units (PICU), the most common being central line–associated bloodstream infection (CLABSI) 25–30%, followed by ventilator-associated pneumonia (VAP) 20–25%, and others such as catheter-associated urinary tract infection (CAUTI) 15%, surgical site infection (SSI) 11%. HAIs complicate the course of the disease, especially the critical one, thereby increasing the mortality, morbidity, length of hospital stay, and cost. The incidence of HAI in Western countries is 6.1–15.1% and in India, it is 10.5 to 19.5%. The advances in healthcare practices have reduced the incidence of HAIs in the recent years which is possible due to strict asepsis, hand hygiene practices, surveillance of infections, antibiotic stewardship, and adherence to bundled care. The burden of drug resistance and emerging infections are increasing with limited antibiotics in hand, is still a dreadful threat. The most common manifestation of HAIs is fever in PICU, hence the appropriate targeted search to identify the cause of fever should be done. Proper isolation practices, judicious handling of devices, regular microbiologic audit, local spectrum of organisms, identification of barriers in compliance of hand hygiene practices, appropriate education and training, all put together in an efficient and sustained system improves patient outcome.

RESUMO

Objective: The present study evaluates the immunoexpression of p16 and Ki-67 in cervical squamous intraepithelial lesion (SIL) and carcinomas and correlates their expression with clinicopathological features and HPV-DNA status. Material and Methods: A total 36 included cases of SIL and squamous cell carcinoma (SCC) were subjected to p16 and Ki-67 immunostaining. p16 staining was evaluated depending on grading, distribution, localization pattern, intensity and IHC score. Ki-67 expression was graded based on percentage of positive cells. Results: Incidence of HSIL and SCC cases was found to be significantly increased with parity > 5. p16 grade III diffuse nucleocytoplasmic immunostaining was observed in 62.5% LSIL, 80% HSIL and 87% SCC cases. Significant association of p16 staining intensity, IHC score and Ki-67 indices was noted with increasing grades of SILs and carcinomas. Conclusion: Our experience indicates that a combination of p16 and Ki-67 immunostaining may be useful to determine the severity of dysplastic change.

RESUMO

Background: Predicting the severity of COVID-19 infection in advance is the key to success of its treatment outcome. Various scoring systems are used to detect the severity of this disease but this study targets three simple scoring systems based on the vital parameters and basic routine laboratory tests. Aims and Objectives: The aim of the study was to assess the predictability of three scoring systems (Quick sequential organ failure assessment [q SOFA], CURB-65, and Early Warning scoring system) for disease severity at presentation in a rural-based tertiary care center. Materials and Methods: An observational, descriptive, retrospective, and cross-sectional study was conducted at Diamond Harbour Government Medical College Covid Hospital from January 2021 to January 2022 to assess the predictability of q SOFA, CURB-65, and Early Warning scoring system for disease severity at presentation. Results: The total number of participants was 561 among total admitted 1367 patients. A short descriptive analysis obtained from the variables to analyze the scorings howed among total sample collected, 57% were male and 43% were female. In this study, 87% of patients were survived and the rest 13% succumbed (death). There is no statistically significant difference in mortality between both genders. Age, pulse rate, and respiratory rate have a significant correlation with the outcome and altered sensorium is also highly associated with mortality. The accuracy was also found to be little higher for National Early Warning score (NEWS) score than CURB-65 scoring and q SOFA scoring (0.919, 0.914 and 0.907). Although all the scoring systems have high sensitivity (>90%) (CURB 65: Most sensitive [0.99]), the specificities of all three scoring systems are below 50%. Among these three-scoring systems, NEWS showed the highest specificity (0.492) than q SOFA (0.423) and CURB 65 (0.394). Conclusion: We suggest NEWS score and CURB-65 as a better predictor for in-hospital mortality in COVID-19 patients as it is significantly sensitive and reasonably specific. It can be recommended in less equipped hospitals where only basic laboratory facilities are available. qSOFA can be utilized where no laboratory facility is available like in safe home and isolation centers.
