Geant4 Simulation for Radon Propagation in Soil

Radon is a radioactive element in the periodic table that is generated from the decay of radium below the earth’s surface. After a generation, it travels through the soil and reaches the earth’s surface. Radon poses a radiological health risk. Therefore, the research community pays close attention to radon. This thesis reviews the complete process of radon propagation from soil to air and studies the effects of different environmental and geological parameters which influence radon flux. A Geant4 simulation program based on C++ has been developed to study radon propagation in soil. The process of simulation setup and the results of this simulation study will provide detailed knowledge of the effect of moisture content and grain size on the radon emanation coefficient. Apart from the simulation, the analysis of data gathered by the experimental setup of Geiger counters deployed at Stone Mountain is provided

Current pattern of adverse drug reactions to anti-retroviral therapy in an antiretroviral therapy centre attached to a government medical college of Maharashtra, India: a retrospective study

Background: Antiretroviral drug therapy (ART) has brought a ray of hope to people living with HIV/AIDS. Adverse drug reactions (ADRs) can often cause significant morbidity among individuals on ART, occasionally leading to mortality. The present study was conducted to assess the nature, causality, severity of ADRs to ART, and to identify risk factors for ADRs in HIV-positive patients receiving ART in India.Methods: A total of 109 patients reported with ADRs to ART during July 2015-December 2015 were randomly included in a retrospective observational study conducted at an ART center attached to a government medical college of Maharashtra. Causality and severity assessment of ADRs was done by using Naranjo’s ADR Causality scale and Modified Hartwig and Siegel scale respectively. The data was computed using MS Excel and descriptive results were expressed as counts and percentages. The study was approved by Institutional Ethics Committee.Results: Among 109 patients, females (60.55%) had higher prevalence of ADRs than males (39.45%). A total of 132 ADRs were reported. Anemia (76.52%) was the commonest ADR reported followed by skin rash (11.36%) and raised renal function tests (6.06%). Zidovudine + Lamivudine + Nevirapine (ZLN) were the commonest ART regimen causing anemia as ADR.Conclusions: Reporting of ADRs is a very inefficient system in detecting drug-related conditions, leading to underestimation of the burden due to ADRs in India. A well-structured, efficient pharmacovigilance systems, which assesses and monitor safety profile and impact of antiretroviral medicines is very much needed at present in India

Parametrical modeling and design optimization of blood plasma separation device with microchannel mechanism

This paper presents an analysis of biofluid behavior in a T-shaped microchannel device and a design optimization for improved biofluid performance in terms of particle liquid separation. The biofluid is modeled with single phase shear rate non-Newtonian flow with blood property. The separation of red blood cell from plasma is evident based on biofluid distribution in the microchannels against various relevant effects and findings, including Zweifach-Fung bifurcation law, Fahraeus effect, Fahraeus-Lindqvist effect and cell free phenomenon. The modeling with the initial device shows that this T-microchannel device can separate red blood cell from plasma but the separation efficiency among different bifurcations varies largely. In accordance with the imbalanced performance, a design optimization is conducted. This includes implementing a series of simulations to investigate the effect of the lengths of the main and branch channels to biofluid behavior and searching an improved design with optimal separation performance. It is found that changing relative lengths of branch channels is effective to both uniformity of flow rate ratio among bifurcations and reduction of difference of the flow velocities between the branch channels, whereas extending the length of the main channel from bifurcation region is only effective for uniformity of flow rate ratio

N. Agashe Charitable Hospital, Satara. Patient was treated with an integrated approach of ayurveda. According to Ayurveda, treatment of Udar is Nityavirechana (purgative), Agnideepan (increase appetite), Balaprapti (increase strength), Yakrituttejjak (stimulant for hepatic function and external application of Arkapattbandhan (belt made by leaves of Calotropis procera). In this study we used the Gandharvahasta Sneha with Dashmula Kwatha as purgative. Appreciable results were observed in the form of reduction in abdominal girth, decreased pedal edema, increased appetite, increased strength and significant changes in investigations

Impact of anti-epileptic drugs on cognition: a review

Epilepsy is a chronic disorder of brain caused by various factors which may vary according to the patient age. In epilepsy threshold for seizure generation get reduced. It may affect patient’s living and increases morbidity. Anti-epileptic drugs are given as mono or poly-therapy for seizure control. These anti-epileptics produce side-effects which are dose and duration of the treatment dependent. One of the important side effects is impact on cognitive function of the patient. However, some anti-epileptic medications also cause improvement in the cognitive function. Newer anti-epileptics are providing better compliance and impact as compared to older ones. This review article provides details of impact of anti-epileptic drugs on cognitive functioning

High sensitivity C - reactive protein (hs-CRP) and clinical characteristics, endocrine, metabolic profile in Indian women with PCOS: a correlation

Background: Role of hs-CRP was studied in PCOS women.Methods: Correlation between serum hs-CRP and endocrine, metabolic profile was studied in 30 healthy women and 88 PCOS women. In PCOS women correlation between hs-CRP and clinical characteristics viz obesity, infertility, acne, hirsutism, acanthosis nigricans (AN) was also studied. Serum levels of hs-CRP, Luteinizing hormone (LH), Follicle stimulating hormone (FSH), LH:FSH ratio, Testosterone (Testo), fasting insulin, fasting blood glucose (FBG), total cholesterol (TC), triglyceride (Tg), low density lipoprotein (LDL), high density lipoprotein (HDL) and Homeostasis Model Assessment (HOMA) were estimated.Results: Mean serum hs-CRP in PCOS women was higher than that in control women (6.9 ± SE 0.84 v/s 2.0 ± SE 0.19mg/L, P=0.005).  In PCOS group overweight/obese had higher hs-CRP as compared to normal weight women (P=0.0051). In control group hs-CRP was positively correlated with age (r=0.385 p=0.035) and LDL (r=0.38 P=0.036). PCOS women showed positive correlation between hs-CRP and cholesterol, LDL, fasting insulin, HOMA. PCOS women showed a significant negative correlation between hs-CRP and LH. AN positive PCOS women showed higher serum hs-CRP levels as compared to AN negative PCOS women (11 ± SE 0.7 v/s 5.5 ± SE 2.3, P=0.0439).Conclusions: Serum hs-CRP is raised in Indian PCOS women reflecting association of low grade chronic inflammation. A positive correlation is present between hs-CRP and AN, insulin in PCOS women and obesity may aggravate this association. A positive correlation between hs-CRP and TC, LDL in the background of normal lipid profile is suggestive of precedence of chronic inflammation over dyslipidemia in PCOS

The aim of the present study was to understand the trends in prescription pattern of oral anti-diabetic drugs among type 2 diabetes mellitus (T2DM) patients attending medicine outpatient department of tertiary care hospital of Western Maharashtra. Methods: A prospective observational study was conducted at Medicine OPD of Government Medical College and Hospital, Miraj. All adult patients (≥18 years) diagnosed with T2DM and willing to give informed consent to participate in the study, were enrolled. The study was approved by Institutional Ethics Committee. The data was computed using MS excel and results were expressed as counts and percentages. Results: Out of 72 T2DM patients enrolled, male population (58.33%) had higher prevalence than females (41.67%). Biguanides (63.16%) were the most commonly prescribed class of oral antidiabetic drugs followed by sulfonylureas (35.09%). Metformin (63.16%) was the most commonly prescribed oral antidiabetic drug followed by glimepiride (30.70%). Combination of oral antidiabetic drugs (OADs) were prescribed in 52.78% and 47.22% patients were prescribed single drug. ‘Metformin and glimepiride’ was the most commonly prescribed combination. Conclusions: In a chronic disease like diabetes mellitus, constant follow up for successful management is a must. It also demands active participation by the patients. Continuing education for the clinicians to keep themselves abreast of the latest development will also contribute in the effective management of diabetes mellitus and rational prescription of antidiabetic drugs

Effect of anti-epileptic drugs on cognitive functions: a prospective study in individuals with newly diagnosed complex partial seizure and generalized tonic clonic seizure

Background: Epilepsy, the third most common neurologic disorder, deteriorates cognitive functions of the patients. Approximately 1% of the world’s population is suffering from epilepsy. Opinions regarding impact of anti-epileptic drugs on cognition are divided. So, this study was designed to assess the impact of anti-epileptic drugs on cognitive performance of patients with complex partial seizure and generalized tonic clonic seizure in Department of Medicine, at Government Medical College, Surat, Gujarat, India.Methods: In present study, cognitive functions were assessed in 50 patients of newly diagnosed complex partial seizure and generalized tonic clonic seizure coming to the Department of Medicine, Surat. The cognitive functions were evaluated by Addenbrooke’s Cognitive Examination (ACE)-III, which assessed memory, attention, fluency, language and visuo-spatial abilities. Follow-up was done after six months of baseline.Results: Baseline and Follow-up data from 50 patients were analysed. Patient treated with anti-epileptic drugs showed significant improvement in memory, attention, language and visuo-spatial abilities whereas improvement in fluency was not significant. Paired t-test and Wilcoxon Signed Ranks Test were used to analyse the data. For statistical analysis of data SPSS 19.0 software was used.Conclusions: The available data indicate that the anti-epileptic drugs on short-term administration do not adversely affect cognitive function in patients with newly diagnosed CPS and GTCS. Importantly, the data suggest that the effects exerted by AEDs could depend on factors linked to patient characteristics and individual susceptibility and to comment on those factors further studies are needed
