Nationwide surveillance for Telmisartan alone or with combination at real world therapy in Indian patients with hypertension (START)
Background: Angiotensin receptor blockers (ARBs) are amongst the most preferred class of antihypertensive as reported at various evidences or guidelines. However, choice amongst ARBs differs between practicing physicians in real-life scenario. This survey aimed to understand the usage preferences of telmisartan therapy alone and in combination for treating hypertension (HT) among practitioners at various clinical settings in real-life scenario in India.Methods: A cross‑sectional survey was conducted with a pre-validated survey questionnaire consisting of 15 questions pertaining to the telmisartan and its combination usage in HT management. Total 498 registered medical practitioners (mostly physicians and cardiologists) had participated in survey. They were approached for seeking their perception, opinions, and prescribing behaviour. Categorical data was summarized by number (n) and percentage (%) in each category. Data were summarised in frequency tables.Results: Key findings from the data analysed were as follows: Around 20-40% of patients been reported to have co-morbid hypertension and diabetes as reported by majority of the physicians. Preferred class of drug in patients with hypertension with diabetes reported to be ARB. Around 90.36% of doctors reported that telmisartan was the most preferred ARB in patients with hypertension associated with high cardiovascular risk. Around 90.76% of doctors reported for their preference for telmisartan in patients with hypertension for 24-hr BP control. Around 82.93% of doctors preferred telmisartan in patients with hypertension and stroke/post-MI status.Conclusions: Indian healthcare practitioners prefer telmisartan as the most preferred ARB either alone or in a combination in patients with hypertension, including those with comorbidities
Biochemical and Molecular Mechanisms of Folate Transport in Rat Pancreas; Interference with Ethanol Ingestion
Folic acid is an essential nutrient that is required for one-carbon biosynthetic processes and for methylation of biomolecules. Deficiency of this micronutrient leads to disturbances in normal physiology of cell. Chronic alcoholism is well known to be associated with folate deficiency which is due, in part to folate malabsorption. The present study deals with the mechanistic insights of reduced folate absorption in pancreas during chronic alcoholism. Male Wistar rats were fed 1 g/kg body weight/day ethanol (20% solution) orally for 3 months and the mechanisms of alcohol associated reduced folate uptake was studied in pancreas. The folate transport system in the pancreatic plasma membrane (PPM) was found to be acidic pH dependent one. The transporters proton coupled folate transporter (PCFT) and reduced folate carrier (RFC) are involved in folate uptake across PPM. The folate transporters were found to be associated with lipid raft microdomain of the PPM. Ethanol ingestion decreased the folate transport by reducing the levels of folate transporter molecules in lipid rafts at the PPM. The decreased transport efficiency of the PPM was reflected as reduced folate levels in pancreas. The chronic ethanol ingestion led to decreased pancreatic folate uptake. The decreased levels of PCFT and RFC expression in rat PPM were due to decreased association of these proteins with lipid rafts (LR) at the PPM
Epigenetic modulators as therapeutic targets in prostate cancer
Prostate cancer is one of the most common non-cutaneous malignancies among men worldwide. Epigenetic aberrations, including changes in DNA methylation patterns and/or histone modifications, are key drivers of prostate carcinogenesis. These epigenetic defects might be due to deregulated function and/or expression of the epigenetic machinery, affecting the expression of several important genes. Remarkably, epigenetic modifications are reversible and numerous compounds that target the epigenetic enzymes and regulatory proteins were reported to be effective in cancer growth control. In fact, some of these drugs are already being tested in clinical trials. This review discusses the most important epigenetic alterations in prostate cancer, highlighting the role of epigenetic modulating compounds in pre-clinical and clinical trials as potential therapeutic agents for prostate cancer management.info:eu-repo/semantics/publishedVersio
Cancer notification in India
In many developed countries, notification of cancer cases is compulsory. Developing countries including India accounts for more than half of new cancer cases in the world, however notification of cancer is not yet mandatory. The primary purpose of notification is to effect prevention and control and better utilization of resources. It is also a valuable source for incidence, prevalence, mortality and morbidity of the disease. Notification of cancer will lead to improved awareness of common etiologic agents, better understanding of common preventable causes and better utilization of health resources with better monitoring and evaluation of the effectiveness of health programs such as cancer screening and cancer treatment programs, which ultimately might improve survival. Notification of cancer can be done by the doctor or the hospital. Akin to the integrated disease surveillance project where more than 90% of the districts report weekly data through E-mail/portal, notification of cancer can be implemented if it is incorporated into the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke scheme. The need of the hour is cancer notification in India
Anaplastic large cell lymphoma: A single institution experience from India
Background: Systemic anaplastic large cell lymphoma (ALCL) accounts for 2-8% of non-Hodgkin′s lymphoma in adults and 10-15% in children. While there is ample data in the world literature about the clinical features and outcome of this disease, prognosis in Indian patients is largely unknown.
Objective: To study the clinical, pathologic profile and outcome ALCL.
Materials and Methods: Fifty patients who had pathologically proven diagnosis of systemic ALCL at our institute from June 2003 to May 2011 were included for retrospective analysis. This included 30 cases of anaplastic lymphoma kinase+ (ALK+), ALCL and 20 cases of anaplastic lymphoma kinase- (ALK−), ALCL. The hospital protocol for treatment of these patients included CHOP chemotherapy regimen in >15 years of age and MCP842 protocol with vinblastine for 1 year in <15 years of age. Event free survival was noted. These outcomes were correlated with ALK status, International Prognostic Index (IPI) score, and stage at presentation.
Results: At a median follow-up of 36 months (range: 6-72 months) ALK− ALCL had a poor outcome. The 3 year event free survival in pediatric ALCL was 66.7%. In adults, this was 60% ALK+ ALCL was 60% and 20% in ALK− ALCL.
Conclusions: Systemic ALCL is an aggressive disease. CD3 + positivity is commonly seen in ALK− ALCL and ALK+, epithelial membrane antigen + positivity is seen in ALK+ ALCL. ALK− ALCL, advanced stage III, IV and high IPI score were associated with poor prognosis. The demographic profile and outcome in our study was similar to the world literature. With new drugs like crizotinib and brentuximab vedotin the future looks very promising

Abstract- The channel estimation techniques for OFDM systems based on pilot arrangement are investigated. The channel estimation based on comb type pilot arrangement is studied through different algorithms for both estimating channel at pilot frequencies and interpolating the channel. The estimation of channel at pilot frequencies is based on LS and LMS while the channel interpolation is linear interpolation, second order interpolation, low-pass interpolation, spline cubic interpolation, and time domain interpolation. Time-domain interpolation is obtained by passing to time domain through IDFT, zero padding and going back to frequency domain through DFT. In addition, the channel estimation based on block type pilot arrangement is performed by sending pilots at every sub-channel and using this estimation for a specific number of following symbols. We have also implemented decision feedback equalizer for all sub-channels followed by periodic block-type pilots. We have compared the performances of all schemes by measuring bit error rate with 16QAM, QPSK, DQPSK and BPSK as modulation schemes, and multipath rayleigh fading and AR based fading channels as channel models. Index Terms: linear interpolation, spline cubic interpolation, 16QAM, QPSK, DQPSK and BPSK 1
