Virological study of an epidemic of febrile illness with haemorrhagic manifestations at Kanpur, India, during 1968*

Several epidemics of febrile illnesses associated with haemorrhagic manifestations occurred in India during 1963 and 1964. These epidemics were restricted to the eastern coastal areas. However, in northern India, for the first time, a widespread epidemic of febrile illness associated with haemorrhagic manifestations occurred at Kanpur in 1968. In the present study, the virological findings of the epidemic are reported

Depression and Cognitive Impairment among Community-dwelling Older adults in Southern India

Background: Depression and cognitive impairment are two psychosocial health problems significantly affecting the quality of life of older adults across the globe. This study aimed to estimate the prevalence of psychosocial morbidities among older adults in a rural community of coastal Karnataka, India, and to determine the socio-demographic correlates of these morbidities.Methods: This cross-sectional study was conducted in rural and semi-urban Udupi taluka, in southern India. A total of 1,832 men and women aged ≥60 years were surveyed from 2015 to 2017 using a simple random method. Data was collected from the participants through an interviewer-administered pre-designed semi-structured questionnaire, Geriatric depression scale-Short version, and Everyday Abilities Scale India, and data were analyzed using SPSS version 26.0. Prevalence of depression and cognitive impairment among the study participants were reported, and significant sociodemographic predictors of these morbidities were determined using multivariate analysis.Results: Prevalence of depression and cognitive impairment were 38.7% and 49.1%, respectively, among older adults. Low literacy, low socioeconomic status, and unemployment were significant predictors of depression, while only low literacy was found to be the predictor of cognitive impairment. Further, being employed in old age showed a protective effect on their cognitive health.Conclusion: Psychosocial problems were highly prevalent among community-dwelling older adults. Improving their general health conditions, getting them involved in social activities tailored to their abilities and preferences, and ensuring economic independence through social security measures would pave the way in enhancing the mental health of older adults in southern India

Urothelial carcinoma of the graft kidney with molecular analyses: a rare case report

Abstract Background Malignancy after transplantation is a leading cause of death among kidney transplant recipients. However, donor-derived malignancies are rare. We report a case of a high grade papillary urothelial carcinoma arising in a transplanted kidney. Case presentation A 62-year-old female who received a kidney transplantation more than 30 years ago presented with urinary tract infection, acute renal failure, and hydronephrosis of the transplant kidney. Anterograde nephrostogram showed a large filling defect in the lower pole of the transplant kidney and in the proximal 3–4 cm of the ureter. A biopsy from the renal pelvic mass showed a high grade urothelial carcinoma. She underwent an anterior exenteration, resection of both transplant and native kidneys and bilateral pelvic lymph node dissection. Pathologic examination showed a high grade papillary urothelial carcinoma which appeared to arise in the pelvis of the graft kidney, involve the graft ureter and native urinary bladder. The tumor had metastasized to one left obturator lymph node but spared the two native kidneys and ureters. Short tandem repeat (STR) analysis confirmed the tumor to be of donor origin. Next-generation sequencing identified amplification of TERT and loss of CDKN2A/CDKN2B in the primary tumor. Conclusion While it is known that transplant recipients have an increased risk of urothelial carcinoma compared to the general population, the lack of the well-documented risk factors, such as older age at transplantation, BK polyomavirus infection, and prolonged post-transplantation history and dissemination of the tumor in this case shed light on the de novo tumorigenesis of the graft kidney within the host microenvironment. Amplification of Telomerase reverse transcriptase (TERT) and loss of cyclin dependent kinase inhibitor 2A/2B (CDKN2A/CDKN2B) detected in the tumor by next gene sequencing suggests that they may play an important role in this case

A clinical and epidemiological study of an epidemic of febrile illness with haemorrhagic manifestations which occurred at Kanpur, India, in 1968

An epidemic of febrile illness associated with haemorrhagic manifestations and shock occurred at Kanpur, India, during 1968. The epidemic was widespread in the city, involving about one-tenth of the population; cases were more frequent in thickly populated localities with poor sanitary conditions. Those affected were mainly adolescents and adults of both sexes and multiple cases occurred in families. The disease was characterized by the sudden onset of fever, associated with severe headache and low backache. A number of patients had bradycardia, vomiting and diarrhoea and macular skin rashes associated with itching. A small percentage of the patients had haemorrhagic manifestations in the form of haematemesis, haemoptysis, melaena, haematuria and bleeding per vaginum. The mortality was very low. Dengue type 4 virus has been implicated in the epidemic
