Healthcare Innovation Lifecycle and Policy Ecosystem: Insights from India.

Purpose: Healthcare innovations are one of the drivers of healthcare sector growth in India. Innovation policies are challenging because of the uncertainty regarding the outcome of the innovations. Hence, there is a need to understand the interface between policies and healthcare innovations to identify gaps and propose timely recommendations. Acoordingly, this study uses the Indian healthcare startup sector as a case study to analyse the above linkages, gaps and propose recommendations. Methodology: Quantitative data from the startup India portal along with qualitative data from key informant interviews have been analysed to draw insights. Findings: Healthcare startups have made significant contributions to the economy and healthcare sector, but there are gaps and room for improvement especially in the areas of awareness, funding and mentoring. Conclusions: Based on the study findings a conceptual framework has been created for understanding the nature of gaps and their linkages in the healthcare innovation lifecycle.

Impaired glucose tolerance in dengue fever: A case-control study

Background: Studies on dengue fever demonstrated that the dengue viral infection of pancreas is often associated with disease morbidity and complication. Aims and Objectives: The pancreas-pathogen interactions in dengue-infected persons were evaluated using endocrine deregulation as an investigation marker of complication. Materials and Methods: A prospective observational study was conducted in a tertiary care medical college and hospital of West Bengal, over 1 year and 4 months. Blood samples from 286 cases and 258 controls were collected on day 2. After plasma glucose determination, 44 cases and 39 controls were excluded as frank cases of diabetes mellitus. On day 6, fasting and 2 h postprandial plasma glucose estimation were done in 73 cases and 61 controls by glucose oxidase-peroxidase method using autoanalyzer. Data were analyzed using the Statistical Package for the Social Sciences version 20.0. Results: The prevalence of impaired glucose tolerance was higher in cases on day 2 than on follow-up on day 6 (12.3% vs. 8%). There existed no statistical difference in terms of fasting plasma glucose between cases and control on day 2 and day 6 and postprandial (PP) plasma glucose on day 2. However, the PP values on day 6 in cases were significantly higher in cases in comparison to controls (P = 0.006). Among cases, day 6 values were higher than day 2 values (0.016). Conclusion: Dengue viral infection correlates with the involvement of the pancreas in terms of impaired tolerance to glucose which has implications for understanding disease pathogenesis in terms of developing chronic complications.

Predicting the Anatomical Location of Neck of Femur Fractures in Osteoporotic Geriatric Indian Population

@#Introduction: Neck of femur fractures are quite common fractures in the elderly. Though a lot is spoken about the various modes of management of these fractures across different age groups, hardly any literary support mentioning their distribution, location and pattern can be found. In this study, we aim to find whether the Singh index, as a marker of osteoporosis on digital radiographs, can predict the location of neck of femur fractures in the elderly population. Materials and methods: We accessed 556 fractured hip radiographs in our institution over the past 5 years (2015- 2020) and correlated with the Singh index, as a marker of degree of osteoporosis, on pre-operative pelvis digital radiographs. Mid coronal CT cuts were also corroborated with the radiographic findings. A control group was set up and 361 radiographs were evaluated in the study group. Results: A total of 124 transcervical fractures (73%) were in Singh index 4, while 76 subcapital fractures (70%) were in Singh index 3. A total of 166 fractures (66%) were found in transcervical region in the age group of 60 to 80 years, while 80 fractures (74%) were in the subcapital region in patients above 80 years. Conclusion: We concluded that transcervical fractures were more common in patients with Singh index 4 (p<0.001) and subcapital more common in patients with Singh index 3(p<0.001). There was also a shift in location of the fractures from the transcervical region to the subcapital region with age above 80 years (p<0.001).

Secretory meningioma: A diagnostic pitfall.

Context: Secretory meningioma is a rare subtype of meningiomas, displaying epithelial and secretory differentiation of meningothelial cells. It has unique radiological, morphological, and immunohistochemical features, but runs a benign course. Radiological picture because of the variable degrees of peritumoral edema can be confused with aggressive neoplasms. Morphologically, it is diffi cult to distinguish secretory meningioma from other tumors having a clear cell appearance and aggressive clinical behavior. Materials and Methods: Retrospective analysis over a period of 16 years (1997-2012) brought out fi ve cases diagnosed as secretory meningioma. The slides were restained and subject to special stains and immunohistochemistry and the clinical details were retrieved. Results: On histopathology, the tumors showed a characteristic vacuolated appearance due to the presence of variably sized intracytoplasmic lumina. Another unique feature was the presence of hyaline inclusions within these intracytoplasmic lumina and in the intercellular spaces. These inclusions were periodic acid-Schiff positive diastase-resistant, yellowish-orange on Elastic Van Giesson stain and strongly carcinoembryonic antigen positive. Conclusion: Owing to its rarity and unique morphology secretory meningioma poses a diagnostic challenge to the pathologists. As this tumor follows a benign course, it is crucial to correctly diagnose this entity to avoid unnecessary over treatment.

Enteric fever in an HIV/AIDS patient: atypical manifestations

Bloodstream infections with Salmonella typhi, is uncommon in human immunodeficiency virus [HIV]-infected persons. The symptoms in such patients are often non-specific and have a rather insidious onset and progression. We report a patient with sepsis and lower limb gangrene due to Salmonella typhi infection in an HIV-infected patient.

Lead-induced peripheral neuropathy following ayurvedic medication.

Lead poisoning following intake of Ayurvedic medication is one of the recent areas of concern. We report a case of a 58-year-old type II diabetic man who was stable with diet control and 30 mg pioglitazone per day. He took Ayurvedic medication for generalized weakness and developed peripheral neuropathy following its intake. He was found to have high blood and urinary lead levels and was diagnosed to have subacute lead poisoning. He was treated with d-Penicillamine for 8 weeks, following which his lead levels became normal. The use of d-Penicillamine was proved highly effective in treating a case of lead poisoning.

Rational use of glucocorticoid during pituitary surgery--a pilot study.

BACKGROUND & OBJECTIVE: The conventionally used perioperative glucocorticoid replacement protocol in patients with pituitary tumours is far from optimal. In this study we evaluated the validity of a modified protocol for perioperative glucocorticoid replacement in non-functioning pituitary macroadenomas. METHODS: A total of 24 consecutive patients with non functioning pituitary macroadenomas were included in this interventional study. Patients with a pre-operative 0800 h cortisol of > or = 350 nmol/l (> or = 12.6 microg/dl) did not receive glucocorticoid replacement during perioperative (d(0)-d-(2)) period, while those with < or = 100 nmol/l (< or = 3.6 microg/dl) received glucocorticoid replacement. Those patients with 0800 h cortisol value between > 100-349 nmol/l (> 3.6-12.6 microg/dl) required them to undergo an insulin induced hypoglycaemia (IIH). In response to IIH, patients with a peak cortisol of < 550 nmol/l (< 19.8 microg/dl) received glucocorticoid replacement. Post-operatively, patients on day 3 with 0800 h cortisol of < or = 100 nmol/l (< or = 3.6 microg/dl) received hydrocortisone 10 mg/m(2) per day; those between > 100-449 nmol/l (> 3.6-16 microg/dl) received hydrocortisone replacement only if they had symptoms of adrenal insufficiency (AI) or during stress; while patients with > or = 450 nmol/l (> or = 16.0 microg/dl) did not receive any glucocorticoid replacement. Retesting was done at 12 wk in 23 subjects based on the algorithm. RESULTS: Pre-operatively, 8 (35%) patients were hypocortisolic and received glucocorticoid supplementation, thereby sparing 15 (65%) subjects from glucocorticoid replacement. On d(3) of surgery, 13 (57%) patients were hypocortisolic, but only 6 with serum cortisol of < or = 100 nmol/l (< or = 3.6 microg/dl), had symptoms and were substituted with glucocorticoid. Remaining seven patients, with serum cortisol between >100-349 nmol/l (> 3.6-12.6 microg/dl), were asymptomatic and advised glucocorticoid support only during stress but none required. Overall, 17 (74%) patients were spared from unnecessary glucocorticoid support. At 12 wk, 13 (57%) patients were hypocortisolic and only 6 either with serum cortisol level of < or = 100 nmol/l (< or = 3.6 microg/dl) or symptomatic for AI received glucocorticoids. Post-operative complications including diabetes insipidus and CSF leak remarkably decreased. INTERPRETATION & CONCLUSION: The protocol used was safe and spared unnecessary use of glucocorticoids peri- and post-operatively. However, more number of patients are to be studied to substantiate the validity of this protocol.

Ghosal type hemato-diaphyseal dysplasia: a rare variety of Engelmann's disease.

Ghosal type hemato-diaphyseal dysplasia is a recently described clinical entity. The authors describe such a case with severe anemia requiring transfusions and with clinical and radiological evidence of diaphyseal dysplasia. Very few such cases are reported in world literature.

Raised intracranial pressure in hepatic encephalopathy.

Intracranial hypertension secondary to cerebral edema is the cause of death in 50%-80% of patients with fulminant hepatic failure (FHF). This is rarely seen in chronic hepatic failure. The genesis of cerebral edema in FHF is poorly understood. The grade of encephalopathy and coagulopathy are the most important predictors of outcome in FHF. However, it is important to emphasize that intracranial pressure (ICP) may not reflect clinical course. Decerebrate posturing may be seen with ICP recording of 16 mmHg, while a quarter of the patients may have brain damage without clinical signs of raised ICP. ICP monitoring is therefore vital. The gold standard for ICP monitoring is the intraventricular method. Non-invasive methods like computerized tomography scan and magnetic resonance imaging have poor correlation with ICP. Other methods like transcranial Doppler and jugular venous oximetry measurement of brain metabolites need evaluation. The main indications for ICP monitoring in FHF are (a) patients in grade III or IV encephalopathy and (b) patients undergoing liver transplantation. Generally, patients with an ICP >40 mmHg with cerebral perfusion pressure <50 mmHg for over 2 hours are poor subjects for liver transplant.

Suprasellar malignant mixed germ cell tumour presenting as craniopharyngioma.

A 15 year old boy presented with diminution in vision of both eyes, diabetes insipidus and hypopituitarism. MRI was suggestive of a large suprasellar and retrosellar craniopharyngioma with stretching of the optic chiasma. Histopathological findings on the first surgical specimen were interpreted as a craniopharyngioma. He was reoperated on account of clinical deterioration and increase in tumour size. Histological examination this time revealed derivatives of all three germ cell lineages along with areas of embryonal carcinoma, and yolk sac tumour besides squamous cysts, establishing the diagnosis of malignant mixed germ cell tumour. Serum and CSF were strongly positive for alpha foetoproteins.

A mathematical outcome prediction model in severe head injury: a pilot study.

103 patients of head injury, with a Glasgow coma scale (GCS) score of 8 or less, were studied prospectively. GCS score, brain stem reflexes, motor score, reaction level scale, and Glasgow Liege scale were evaluated as prognostic variables. Linear logistic regression analysis was used to obtain coefficients of these variables and mathematical formulae developed to predict outcome in individual patients.

Perception and practice regarding pulse polio immunisation in an urban community of Calcutta.

A survey was conducted at an Integrated Child Development Services (ICDS) Scheme project in North Calcutta among 656 mothers having children less than 3 years of age to assess their perception and practice regarding pulse polio immunisation (PPI). It was revealed that 91.8% of under 3-year children received PPI on 9-12-1995 and 94.4% on 20-1-1996. Major reasons for not accepting the services on those two days included 'mothers unaware' (22%), 'child too small' (30.5%), etc. Major source of first information was television (TV)/radio (57.2%) followed by anganwadi workers (AWWs) (33.8%). However, majority of the mothers were finally motivated for PPI by AWWs (58.8%) followed by the role of TV/radio (34.1%). Although 70.7% mothers knew the name of the vaccine correctly, only 3.5% mothers could tell the exact purpose of its administration. Most mothers (73%) opined that 2 drops of oral polio vaccine (OPV) was administered to their children and only 14.6% hoped that such programmes will be conducted by the Government in future. The average waiting time of mothers at immunisation centres was found to be 7.2 minutes.

Detection of HIV seropositivity during an outbreak of Japanese encephalitis in Manipur.

An epidemic outbreak of Japanese encephalitis (JE) occurred during mid 1995. Sixteen serum samples from patients with history of febrile headache, convulsions, mental confusion, neck rigidity etc. were sent to the Department of Virology, School of Tropical Medicine, Calcutta, in August, 1995. Twelve (75%) showed HIV antibody against JEV. Out of these 12 sera showing HIV antibody titre between 1:40 and 1:160, eight (66.6%) showed IgM antibody, giving the presumptive diagnosis of recent JEV infection. Five of these 16 sera showed HIV seropositivity (31.25%). Concomitant JEV and HIV infection could be detected in 3 cases. However, in 2 sera HIV titre were less than 1:20. This is probably the first documentation of concomitant JEV and HIV infection in the eastern India.

HCV activity in Calcutta--a serological study.

HCV infection, a global public health problem is quite prevalent in India. In the present study conducted during February-July 1996 a total of 153 samples of different age groups and of both sexes were tested by ELISA for detection of Anti-HCV antibody. Anti-HCV was found in 13% of multi-transfused cases and in 8.8% cases with multiple needle-stick injury. Maximum seropositivity (20%) could be observed amongst males between 31-40 yrs. age group. HCV activity was noted more in males (13%) than in females (8.2%) and more relatively in subjects without a history of jaundice (11.5%) than those having the features of jaundice (10.5%). An increasing trend has also been observed amongst the multi-transfused cases in Calcutta.

HLA phenotype frequencies in pulmonary tuberculosis.

Susceptibility and/or immune response to tuberculosis may or may not be associated with particular histocompatibility leucocyte antigen (HLA) phenotype frequencies. The present study was undertaken to north eastern Indian population to verify any association between HLA phenotypes and immune response to mycobacterial antigen. HLA-typing was done in 60 well Tarasaki trays and T-cell subsets in each group were measured using Ficoll-hypaque nylon wool columns and dynabeads (M-450). No universal association with particular HLA-type and pulmonary tuberculosis has been confirmed.

A study of inferior vena cava obstruction.

Inferior Vena Cava obstruction as a major cause of hepatic venous outflow block is not so common. A prospective study of 20 cases gave us an opportunity to device a management protocol for this disorder. Out of 20 cases we had studied, 12 had only inferior Vena Cava obstruction while rest of the 8 cases had both hepatic vein and IVC blockade. However, balloon cavoplasty showed remarkable results with substantial clinical and haemodynamic improvement in cases with isolated IVC obstruction. Therefore, we suggest that patients with IVC obstruction should be actively managed with Vena-cavography followed by cavoplasty. Treatment of Hepatic venous obstruction along with IVC obstruction is controversial; bypass shunt is usually required and long term follow-up studies are required to establish safety and efficacy.
