RESUMEN

AIM: To compare and evaluate the mean bite force and masticatory performance of conventional complete dentures (CD) in comparison with the lower implant-supported overdenture opposing an upper CD by using a strain gauge transducer and a test material respectively, in the same patient over a different period of time. MATERIALS AND METHODS: The study included 20 edentulous patients in the age range 45-65 years with a good general and oral health. In the first phase of the study, conventional CD were fabricated and delivered to each patient who participated in the study. A strain gauge transducer was used to analyze the maximum bite force and an agar test material was used to assess the masticatory performance using the sieve method. The existing lower denture was used to deliver a two-implant overdenture system and two implants were placed in the intermental-foraminal region of the mandible. One month after the delivery of implant-supported overdenture, the maximum bite force and masticatory performance were assessed as before. RESULTS: To test two independent variables, the data were analyzed statistically using an unpaired t-test. In comparison to the conventional upper and lower CD rehabilitations, the implant-supported lower denture and conventional upper CD rehabilitations resulted in statistically significant improvements in biting force and masticatory performance. CONCLUSION: Study findings demonstrate that the completely edentulous patients can be rehabilitated with the upper CD and lower two-implant supported overdenture system that offers improved biting force and masticatory performance than conventional upper and lower dentures. CLINICAL SIGNIFICANCE: Masticatory efficiency is one of the important indicators of functional state of stomatognathic system. Determination of individual masticatory performance has been used to ascertain the therapeutic effect of prosthetic device.

RESUMEN

Despite massive fluctuations in its internal triglyceride content, the liver secretes triglyceride under tight homeostatic control. This buffering function is most visible after fasting, when liver triglyceride increases manyfold but circulating serum triglyceride barely fluctuates. How the liver controls triglyceride secretion is unknown, but is fundamentally important for lipid and energy homeostasis in animals. Here we find an unexpected cellular and molecular mechanism behind such control. We show that kinesin motors are recruited to triglyceride-rich lipid droplets (LDs) in the liver by the GTPase ARF1, which is a key activator of lipolysis. This recruitment is activated by an insulin-dependent pathway and therefore responds to fed/fasted states of the animal. In fed state, ARF1 and kinesin appear on LDs, consequently transporting LDs to the periphery of hepatocytes where the smooth endoplasmic reticulum (sER) is present. Because the lipases that catabolize LDs in hepatocytes reside on the sER, LDs can now be catabolized efficiently to provide triglyceride for lipoprotein assembly and secretion from the sER. Upon fasting, insulin is lowered to remove ARF1 and kinesin from LDs, thus down-regulating LD transport and sER-LD contacts. This tempers triglyceride availabiity for very low density lipoprotein assembly and allows homeostatic control of serum triglyceride in a fasted state. We further show that kinesin knockdown inhibits hepatitis-C virus replication in hepatocytes, likely because translated viral proteins are unable to transfer from the ER to LDs.

RESUMEN

OBJECTIVE: To compare the one-shot dilation (OSD) technique with three other dilation techniques namely telescopic Alken, fascial Amplatz and balloon dilation (BD) in terms of safety efficacy and cost effectiveness. METHODS: During a 3½ year enrollment period, 480 patients who required PCNL surgery were equally randomized into four groups. All the cases were assessed preoperatively, intraoperatively as well as postoperatively till a period of 3 months. Access time, X-ray exposure time, hemoglobin drop, complications, success rate, etc., were all assessed and recorded. RESULTS: Similar preoperative characteristics were observed in all the four study arms. X-ray exposure time during dilation was significantly reduced for both OSD and BD when compared to sequential Amplatz and telescopic Alken dilation (Group ALD = 62.1 + 13, Group AMD = 67.0 + 10, Group OSD = 36.8 + 7, Group BD = 38.1 + 6, p value = 0.01, post hoc: G4 = G3 < G2 = G1). There was no significant difference between the access time, hemoglobin drop, complication and success rates among the groups. BD was the most expensive dilation method when compared to the other three dilation techniques. CONCLUSION: All the four methods of dilation are equally safe and effective but both OSD and BD are advantageous in terms of lesser fluoroscopy time during dilation. OSD is much cheaper option when compared to BD, and therefore with more experience, it can become the preferable dilation method, especially in the developing countries.

RESUMEN

We have developed an optical trapping method to precisely measure the force generated by motor proteins on single organelles of unknown size in cell extract. This approach, termed VMatch, permits the functional interrogation of native motor complexes. We apply VMatch to measure the force, number and activity of kinesin-1 on motile lipid droplets isolated from the liver of normally fed and food-deprived rats.

RESUMEN

OBJECTIVE: The purpose of the study was to compare the safety, efficacy and outcome of monopolar transurethral resection of prostate (M-TURP), bipolar transurethral resection of prostate (BP-TURP) and open prostatectomy (OP) exclusively involving large prostate glands in men with renal impairment. METHODS: Data of patients with gland size >90 g and serum creatinine >1.5 mg/dl, who were managed surgically at our institution from April 2009 to March 2014 were analyzed retrospectively. International Prostate Symptom Score (IPSS), quality of life (QoL) scores, PVR, serum creatinine and Q-max were recorded preoperatively and postoperatively at each follow-up visit. Follow-up was performed at 1, 3, 6 and 12 months. RESULTS: M-TURP, BP-TURP and OP were the 3 types of surgeries performed. Preoperative characters were similar in all the groups. Hemoglobin drop, transfusion rates, irrigation time, catheter time and hospital days were significantly more in the OP group. Changes in sodium levels and incidence of transurethral syndrome were found to be more in the monopolar group. The follow-up data indicate a significant improvement in the IPSS, QoL, PVR and Q-max in all the groups. CONCLUSION: This category of patients can be managed safely and efficiently by all the 3 procedures, although BP-TURP has an advantage in terms of shorter catheterization, hospitalization and fewer complications like transurethral resection syndrome.

RESUMEN

Background and Objective: Hypertension is one of the most common medical complications during pregnancy and a leading cause of maternal mortality and morbidity. Severe preeclampsia is defined as blood pressure (BP) >160/110 mmHg with warning signs such as headache, blurring of vision, and epigastric pain. Nifedipine (C17H18N2O6), labetalol (C19H24N2O3), and hydralazine (C8H8N4) are commonly used drugs, and all are recommended as first-line agents. Hydralazine is associated with a higher incidence of adverse outcomes, so oral nifedipine has been proposed as a first-line alternative to intravenous labetalol. Consequently, this study aims to compare the efficacy and safety of oral nifedipine with that of intravenous labetalol. The objective is to compare the ability/effectiveness of oral nifedipine and intravenous labetalol to normalize acute hypertension in severe preeclampsia and to assess the birth outcome. Relations between different factors were established by appropriate statistical tests. The p-value <0.05 was considered statistically significant. Methods: The study was conducted on 120 antenatal women with blood pressure ≥160/110 mmHg admitted to our hospital, a tertiary care center, from January 1st, 2020 to June 30th, 2021. Patients were randomized by a single blinding method to receive intravenous labetalol and oral nifedipine. The primary outcome measures were the time taken to control the blood pressure and the number of doses of drugs required. The secondary outcome measures were the birth outcome like a method of delivery, side effect profile, and the number of admissions in the neonatal intensive care unit. Results: A total of 120 patients were included with 60 patients in each group. The labetalol group took 48.67 ± 17.80 minutes and the nifedipine group took 64.33 ± 9.81 minutes to achieve a target BP of <=140/90 mmHg (p < 0.05). No side effects were seen in 70% of patients in the labetalol group and 71.67% in the nifedipine group (p > 0.05). Conclusion and Global Health Implications: Intravenous labetalol is faster in restoring blood pressure in pregnant women with preeclampsia than oral nifedipine and may be used as a first-line drug in the acute control of blood pressure in a hypertensive emergency during pregnancy. More studies are needed in order to evaluate the findings from this pilot study in a large sample of patients.

RESUMEN

OBJECTIVE: This study aimed to introduce, sensitize, and train our postgraduate students and faculty of the department of general surgery with the use of mini-Clinical Evaluation Exercise (mini­CEX) and to assess the perception of students and faculty towards it. MATERIAL AND METHODS: A cross­sectional observational study was conducted over a period of four months. Ten surgery residents in the department were asked to volunteer to participate and five professors conducted the session. Five sessions of mini­CEX (nine points) were conducted for each resident in different settings of the out­patient department (OPD) and in­patient department (IPD). A total of five skills were tested. Feedback from faculty and residents regarding the perception of mini­CEX was also taken. RESULTS: A statistically significant difference in mean scores of all domains was observed comparing the first and last assessment (p<0.05). Hundred percent of the residents scored superior category (7-9) in the final assessment in all domains, whereas the maximum was in a satisfactory scoring grade in 1st assessment. The time taken for the assessment significantly reduced from 1st assessment to the last assessment in OPD and IPD settings (p=0.001). The mini-CEX assessment tool got 100% feedback from faculty in terms of skill improvement, method, attitude of residents, and ability to identify gaps in knowledge. However, one assessor thought that "time given for assessment" was inadequate and more effort was required than the usual traditional assessment methods. The most identified problem faced by residents was that the "time given during assessment" was less (50%); however, overall residents also found it valid, effective, and helpful in identifying knowledge gaps and improving clinical and communication skills. CONCLUSION: Mini­CEX improves the learning environment in residency and also leads to improvement in medical interviewing skills, physical examination skills, humanistic qualities/professionalism, and counseling skills. So, it can be used for residency training in clinical departments.

RESUMEN

Leprosy is known for its diverse pathophysiologic involvement and resulting multisystemic manifestation and morbidities. Despite global efforts to eliminate this public health illness, it is still prevalent in some Asian and European countries. Perioperative management of a leprosy patient is challenging owing to the indirect and direct involvement of the airway, respiratory, and cardiac systems; treatment-related side-effects involving the hepato-renal systems affecting the anesthesia techniques and drugs pharmacokinetic and pharmacodynamics. While anaesthesiologists are aware of such happenings and often tailor the anesthesia management for the concerning issues, immunological aspects of the disease and drug-related adverse events are less enquired about, such as type-2 lepra reaction, i.e., erythema nodosum leprosum (ENL), etc. Further, data on perioperative ENL management and prevention are still being determined. We report one case of a 52-year-old female who underwent gynecology surgery and developed ENL on the third postoperative day, which was managed using Steroids. Unfortunately, the patient had a surgical site infection, which required another surgery within the month, while the patient was still under the steroid successfully without any adverse events. Although a single case cannot provide causation or association, the case is presented to highlight the probable preventive action of steroids on the occurrence of postoperative ENL, where surgical stress is considered a risk factor.

RESUMEN

Aim and Objective: To evaluate, compare, and correlate the mandibular third molar orientation and available retromolar space with arch length discrepancy in subjects with skeletal class II malocclusion and different growth pattern. Material and Method: A total of 250 patients (age >18 yrs) having skeletal class II malocclusion (based on YEN angle and WITS appraisal) were divided into two groups. Both the groups (Group I with erupted mandibular third molars {N = 150} and Group II with impacted mandibular third molars {N = 100}) were subdivided into subgroups IA (n = 71), IB (n = 19), IC (n = 71) and Group IIA (n = 54), IIB (n = 30) and IIC (n = 16) for normo-, hypo- and hyperdivergent growth patterns, respectively (based on Jarabak ratio and Sn-Go-Gn angle). Four parameters, that is, retromolar space, width of third molar, third molar angulation, and mandibular incisor angulation were measured on orthopantomogram whereas arch length discrepancy was calculated with the help of lateral cephalogram and study model. Intragroup, intergroup comparisons (using unpaired Student's 't' test), and Pearson's correlation coefficient for assessed parameters were obtained. Result: Third molar angulation and retromolar space were significantly higher in Group I than in Group II (hyperdivergent pattern of Group II had highest value). The width of third molar was less than retromolar space in Group II and vice versa for Group I. Mandibular incisor angulation and arch length discrepancy were more in Group II than in Group I, but difference was statistically nonsignificant. Strong positive correlation was observed for mandibular third molar angulation and available retromolar space in normo- and hyperdivergent growth patterns. Conclusion: Lack of retromolar space along with increased amount of arch length discrepancy and mandibular incisor angulation is responsible for increased chances of third molar impaction in some subjects with class II malocclusion.

RESUMEN

OBJECTIVES: Despite significant advancements in modern medicine, effective hepatoprotective medication with minimal side effects is still lacking. In this context. Tinospora cordifolia, an Indian Ayurvedic liana, has attracted much attention. KEY FINDINGS: Traditionally, T. cordifolia has been found to be effective in the treatment of jaundice; according to the literature, T. cordifolia is a hepatoprotective agent, and the CCl4 model is the most frequently used to evaluate its potential. Its hepatoprotective effects might be attributed to alkaloids (berberine, palmatine, and jatrorrhizine) and sinapic acid. Berberine decreases inflammation by inhibiting the proinflammatory cascade triggered by TNF-α and reduces nitrosative stress by inhibiting iNOS. T. cordifolia also exhibits anticancer, anti-inflammatory, antimicrobial, antioxidant, and other activities; it is safe at concentrations up to 2000 mg/kg. Its biological action can be attributed to polyphenols, alkaloids, steroids, terpenoids, and glycosides. T. cordifolia has also been found to be an active ingredient in several polyherbal formulations used to treat chemical-mediated hepatotoxicity. CONCLUSION: T. cordifolia's hepatoprotective effects are mediated by the inhibition of lipid peroxidation, the management of oxidative stress, and other factors. T. cordifolia can be used to manage liver disorders and as a hepatoprotective supplement in the food industry. The bioprospecting of its alkaloids can lead to the development of novel formulations against hepatic ailments.

RESUMEN

PURPOSE: The onset of labor prior to 37 weeks of gestation is preterm labor. Incidence ranges from 5% to 7% of live births in developed countries, but higher in developing countries (10-13%). Preterm birth is a major threat in perinatal health care, as well as a risk factor for neurological impairment and disability. Considering that infection is the major risk factor for preterm labor in rural areas, this study was performed to assess the cytological changes in the cervical mucus of normal-term and preterm labor cases. METHOD: A hospital-based cross-sectional observational study was conducted in the Department of Obstetrics and Gynecology at a tertiary care center in western Uttar Pradesh (UP), India. The sample size calculated was 90. The neutrophil-to-lymphocyte ratio (NLR) in cervical mucus, along with serum inflammatory biomarkers such as CRP and serum alkaline phosphatase, were compared in both groups. RESULT: The incidence of preterm labor increased with an increase in parity, and progression to preterm delivery is faster in the higher parity group. C-reactive protein (CRP) (p value = < 0.001) and serum alkaline phosphatases (taking 220IU/L as the cutoff value), as well as the NLR (p value < 0.001) in cervical mucus in preterm labor, are significantly higher than those in term labor cases, which can be used to predict preterm labor. CONCLUSIONS: Higher levels of serum alkaline phosphatase (> 220 IU/L) and CRP positivity can be used as prognostic markers. Using a cutoff value of 5 for the NLR in the cervical mucus of preterm labor patients proved to be a highly accurate predictor (82.2%) for preterm labor diagnosis.

RESUMEN

In India, unjustified and mass hysterectomy is an alarming issue in rural and semi-urban areas. Fear of cancer and reiterating the idea that uterus removal will alleviate unrelated somatic issues are two methods used to persuade women to have the surgery. It becomes easier to counsel them for hysterectomy, especially when they belong to the rural population, come from lower socioeconomic strata, are young and illiterate, and do nothing for their livelihood. Many patients from the Santhal Pargana division (tribal region) came to gynecology Out Patient Department after having a hysterectomy without any medical indication at an age below 30 years to cure their common symptoms such as lower abdominal pain and vaginal discharge, and this is our major concern from them. We have taken three patients for this case series to highlight this problem at the community level. Unfortunately, the adverse health consequences of early loss of ovarian function accelerate the menopause state, affect multiple systems including cardiovascular, neurological, bone, and connective tissues, and, most importantly, affect the quality of life owing to vasomotor symptoms, mood, sleep, and sexual function. This case series emphasizes the serious complications of unnecessary hysterectomies and problems and gender inequities in the healthcare system for poor women.

RESUMEN

Objective: To study the effect of reassurance and proper mechanical support on quality of life (QOL) and visual analogue score (VAS) pain assessment in patients with mastalgia at a range of follow-ups. Materials and Methods: A prospective follow-up study was conducted among women aged 15-45 years, complaining of breast pain without any abnormality detected clinically and radiologically. After consent to participate and enrollment, all the study participants were counseled and reassured about the non-neoplastic nature of the disease and about wearing proper mechanical support/Bra; this was repeated at each follow-up. VAS was used to assess the pain intensity perceived by the woman at each follow-up, post intervention. The Short Form-36 (SF-36) scale was used to evaluate health related QOL (HRQOL). Results: Among 80 patients, 31.2% were wearing a Bra of fabric other than cotton, 21.2% were wearing a loose fit mechanical support/Brassiere, while 10% were not wearing any mechanical support at baseline. The overall mean VAS score was significantly reduced with each follow-up, indicating decreased perception of breast pain over time. There was a significant difference between the mean SF-36 score between base line and after three months (p<0.0001). Mean scores in all domains of the SF-36 increased. The greatest reduction in mean VAS score was seen in 26-35 years age group and women with a body mass index <18.5 kg/m2. Conclusion: Reassurance and wearing proper mechanical support/Bra are effective for improving QOL and alleviating breast pain/mastalgia. These simple processes should be used for the management of mastalgia.

RESUMEN

Introduction Preeclampsia is a multisystem disorder with hypertension after 20 weeks of gestation. Among many predictors of preeclampsia, vitamin D being one of them is under many studies for establishing a correlation between levels of vitamin D and preeclampsia. Objective To observe a relation between vitamin D levels and preeclampsia and assess related fetomaternal outcomes. Method It is an observational study at the tertiary care center. One hundred twenty patients, out of which 60 were taken as cases with BP>140/90, and 60 were taken as controls with normal BP in a tertiary care center from January 1, 2020, to June 30, 2021. All investigations were sent, and the mode of delivery and the fetomaternal outcome were assessed. Results Compared to normal pregnant patients, preeclamptic patients have significantly lower levels of vitamin D with a p-value of <0.001, which is significant. Conclusion There is a relationship between vitamin D levels and preeclampsia. However, the effects of supplementation of vitamin D on fetomaternal outcomes need further studies.

RESUMEN

Background and Aims: There is an increasing recognition of reinfection in coronavirus disease 2019 (COVID-19). We studied the reinfection of COVID-19 disease among doctors at a tertiary care centre in Northern India. Methods: All COVID-19 patients readmitted for COVID-19 disease after any duration with at least a positive Real time- polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 were included. Their clinical profile, vaccination status, outcome and Centre for disease control (CDC), Atlanta, USA reinfection criteria screening were recorded. Results: A total of 57 (0.53%) doctors were identified and 56 of them satisfied the CDC criteria. It included 13 (20.3%) females and 89.3% of cases were from clinical specialities; 98.2% of individuals had the first infection in 2020 and mean duration between 2 infections was 156.29 ± 76.02 (35-298) days. Duration between two episodes of the disease with more than 90 days apart was in 80.3% cases. One (1.8%) patient developed severe disease and two (3.6%) cases were of moderate severity. Symptoms were similar in both infections except significantly higher number of extra-respiratory complaints (2.2% vs. 9.1%). There were 37.5% cases who had received first dose of vaccination of any duration at the time of second infection. Nine (16.1%) and four (7.1%) patients with more than 4 weeks after the first and second dose of vaccination developed the second infection, respectively. Conclusion: Majority of reinfection were symptomatic and developed after 90 days and so majority followed CDC criteria. Breakthrough infections among vaccinated healthcare worker are real, and with sustained exposure to the virus, they should continue to use precaution including hand hygiene and mask in order to prevent reinfection.

RESUMEN

INTRODUCTION: Lymphatic filariasis causes long term morbidity and hampers the socio-economic status. Apart from the available treatments and medication, control of vector population Culex quinquefasciatus Say through the use of chemical insecticides is a widely applied strategy. However, the unrestrained application of these insecticides over many decades has led to resistance development in the vectors. METHODS: In order to determine the insecticide susceptibility/resistance status of Cx. quinquefasciatus from two filariasis endemic districts of West Bengal, India, wild mosquito populations were collected and assayed against six different insecticides and presence of L1014F; L1014S kdr mutations in the voltage-gated sodium channel gene was also screened along with the use of synergists to evaluate the role of major detoxifying enzymes in resistance development. RESULTS: The collected mosquito populations showed severe resistance to insecticides and the two synergists used-PBO (piperonyl butoxide) and TPP (triphenyl phosphate), were unable to restore the susceptibility status of the vector thereupon pointing towards a minor role of metabolic enzymes. kdr mutations were present in the studied populations in varying percent with higher L1014F frequency indicating its association with the observed resistance to pyrethroids and DDT. This study reports L1014S mutation in Cx. quinquefasciatus for the first time.

RESUMEN

Background The coronavirus disease 2019 (COVID-19) pandemic created an aberrant challenge for healthcare delivery systems, forcing public health policies across the globe to be shifted from traditional medical care in hospitals to virtual care in the homes of patients. To tackle this pandemic, telemedicine had taken center stage. This study aims to learn about patient satisfaction, feasibility, and acceptability of the use of telemedicine for clinical encounters during the COVID-19 pandemic. Methodology This single-center, cross-sectional, observational study was done on a total of 758 patients who were provided with teleconsultations during the COVID-19 pandemic. We developed a 49-item questionnaire consisting of patients' quality of consultation and patients' expectations to evaluate the feasibility, acceptability, and patient satisfaction with their telemedicine consultations. Results The majority of survey participants (97.1%) expressed satisfaction with the quality of the consultations provided through telemedicine. A large percentage of participants (96.8%) reported the benefits of teleconsultation in treating their problems. Overall, 93.3% of participants responded positively to the continuation of teleconsultation services after the pandemic. Conclusions The study revealed a wide extent of satisfaction among patients. The feasibility and acceptability of telemedicine services have transformed the mode of healthcare delivery systems.

RESUMEN

Introduction: Co-infection with different agents such as bacterial, viral, and Rickettsia is being increasingly recognized due to greater availability and utilization of the diagnostic tests among malaria patients. Methods: Consecutive admitted malarial cases were included and were subjected to test for general investigations, bacteria, typhoid, dengue, chikungunya, and rest for specific diagnosis. All patients were followed up till discharge or death and appropriate statistical tests were performed. Results: A total of 152 malaria patients were recruited and 27 (18.8%) had concurrent infections. It included 40.7% dengue only, 18.7% pneumonia, 11.1% urinary tract infection (UTI), 7.4% enteric fever, 3.7% leptospirosis, chikungunya, and tuberculous meningitis each, and 3.7% each of dengue with pneumonia and UTI. The organisms isolated were Streptococcus pneumoniae, Klebsiella pneumoniae, Escherichia coli, Salmonella typhi, and Mycobacterium tuberculosis. The mean duration of fever was 6.33 ± 3.63 days with a range of 3-20 days. Blood culture grew in 2 cases S. typhi and K. pneumonia,e. Dengue co-infections had significantly higher clinical and laboratory features of dengue and complications such as bleeding, jaundice, and cholecystitis, whereas rest concurrent infections had a significantly higher proportion of nausea and vomiting, convulsion, altered sensorium, productive cough, urinary symptoms, shock, acute kidney injury, anemia, and mean neutrophil count. There was significantly higher mortality among malaria-dengue concurrent infection group with 2 (15.4%) than malaria mono-infection group 3 (2.4%). Conclusion: Co-infections with malaria are not uncommon, especially dengue fever and other bacterial infections. The dominant clinical picture is of the superimposed infection. Decision should be clinically guided adjunct with specific diagnostic tests, and timely treatment has favorable outcome.

RESUMEN

Introduction: Newer coexisting conditions should be identified in order to modify newer risk factors. Aim was to identify patients with non-classical or less common coexisting conditions in patients infected of COVID 19. Method: Single centred study from June 2020 to May 2021 at a tertiary centre in North India. A preformed questionnaire was used to record clinical and laboratory parameters and to identify cases which are in addition to CDC list and Indian data. Results: 0.67% (46) cases out of 6832 patients were identified to have non-classical coexisting illness. It was divided into 2 groups-infections A (60.1%) and non-infections B (39.9%). Group A included-tuberculosis- pulmonary (14.3%) & extra pulmonary (32.9%), bacterial (25.0%) viral infections [dengue, hepatitis B & C] (14.3%), HIV disease (10.7%) and malaria (3.6%). Group B included- organ transplant (27.8%), autoimmune [myasthenia gravis, polymyositis, psoriasis] (22.6%), haematologic [Haemophilia, ITP, Aplastic anaemia, APML, CML] (27.8%), uncommon malignancies [disseminated sacral chordoma and GTN] (11.1%) and snakebite (11.1%). Serum Procalcitonin was not helpful for diagnosis of bacterial infection in COVID-19 disease. Group A had significantly longer duration of illness, hepatitis and elevated CRP. The mortality in group A & B were 32.1% and 43.8% respectively. Death in non-severe COVID cases was in tetanus and snakebite. 30.7% death among tuberculosis patients. More than 70% of deaths were attributable to COVID 19 in both the groups. Conclusion: In Indian settings, comorbidities like tuberculosis and bacterial infections can precipitate severe COVID 19 unlike other parts of the world where tuberculosis is relatively uncommon.

RESUMEN

BACKGROUND: Accurate data on type 1 diabetes prevalence, incidence, associated mortality and life expectancy are crucial to inform public health policy, but these data are scarce. We therefore developed a model based on available data to estimate these values for 201 countries for the year 2021 and estimate the projected prevalent cases in 2040. METHODS: We fitted a discrete-time illness-death model (Markov model) to data on type 1 diabetes incidence and type 1 diabetes-associated mortality to produce type 1 diabetes prevalence, incidence, associated mortality and life expectancy in all countries. Type 1 diabetes incidence and mortality data were available from 97 and 37 countries respectively. Diagnosis rates were estimated using data from an expert survey. Mortality was modelled using random-forest regression of published type 1 diabetes mortality data, and life expectancy was calculated accordingly using life tables. Estimates were validated against observed prevalence data for 15 countries. We also estimated missing prevalence (the number of additional people who would be alive with type 1 diabetes if their mortality matched general population rates). FINDINGS: In 2021, there were about 8·4 (95% uncertainty interval 8·1-8·8) million individuals worldwide with type 1 diabetes: of these 1·5 million (18%) were younger than 20 years, 5·4 million (64%) were aged 20-59 years, and 1·6 million (19%) were aged 60 years or older. In that year there were 0·5 million new cases diagnosed (median age of onset 39 years), about 35 000 non-diagnosed individuals died within 12 months of symptomatic onset. One fifth (1·8 million) of individuals with type 1 diabetes were in low-income and lower-middle-income countries. Remaining life expectancy of a 10-year-old diagnosed with type 1 diabetes in 2021 ranged from a mean of 13 years in low-income countries to 65 years in high-income countries. Missing prevalent cases in 2021 were estimated at 3·7 million. In 2040, we predict an increase in prevalent cases to 13·5-17·4 million (60-107% higher than in 2021) with the largest relative increase versus 2021 in low-income and lower-middle-income countries. INTERPRETATION: The burden of type 1 diabetes in 2021 is vast and is expected to increase rapidly, especially in resource-limited countries. Most incident and prevalent cases are adults. The substantial missing prevalence highlights the premature mortality of type 1 diabetes and an opportunity to save and extend lives of people with type 1 diabetes. Our new model, which will be made publicly available as the Type 1 Diabetes Index model, will be an important tool to support health delivery, advocacy, and funding decisions for type 1 diabetes.
