Core conditions for alpha heating attained in direct-drive inertial confinement fusion

It is shown that direct-drive implosions on the OMEGA laser have achieved core conditions that would lead to significant alpha heating at incident energies available on the National Ignition Facility (NIF) scale. The extrapolation of the experimental results from OMEGA to NIF energy assumes only that the implosion hydrodynamic efficiency is unchanged at higher energies. This approach is independent of the uncertainties in the physical mechanism that degrade implosions on OMEGA, and relies solely on a volumetric scaling of the experimentally observed core conditions. It is estimated that the current best-performing OMEGA implosion [Regan et al., Phys. Rev. Lett. 117, 025001 (2016)10.1103/PhysRevLett.117.025001] extrapolated to a 1.9 MJ laser driver with the same illumination configuration and laser-target coupling would produce 125 kJ of fusion energy with similar levels of alpha heating observed in current highest performing indirect-drive NIF implosions.

Analysis of steady state and non-steady state corneal permeation of diclofenac

The present study was undertaken for characterization of the steady state and non steady state corneal permeation kinetics of diclofenac potassium (DCP) using statistical moment theory.

Cluster survey evaluation of a measles vaccination campaign in Jharkhand, India, 2012

Introduction

India was the last country in the world to implement a two-dose strategy for measles-containing vaccine (MCV) in 2010. As part of measles second-dose introduction, phased measles vaccination campaigns were conducted during 2010–2013, targeting 131 million children 9 months to <10 years of age. We performed a post-campaign coverage survey to estimate measles vaccination coverage in Jharkhand state.

Methods

A multi-stage cluster survey was conducted 2 months after the phase 2 measles campaign occurred in 19 of 24 districts of Jharkhand during November 2011–March 2012. Vaccination status of children 9 months to <10 years of age was documented based on vaccination card or mother’s recall. Coverage estimates and 95% confidence intervals (95% CI) for 1,018 children were calculated using survey methods.

Results

In the Jharkhand phase 2 campaign, MCV coverage among children aged 9 months to <10 years was 61.0% (95% CI: 54.4–67.7%). Significant differences in coverage were observed between rural (65.0%; 95% CI: 56.8–73.2%) and urban areas (45.6%; 95% CI: 37.3–53.9%). Campaign awareness among mothers was low (51.5%), and the most commonly reported reason for non-vaccination was being unaware of the campaign (69.4%). At the end of the campaign, 53.7% (95% CI: 46.5–60.9%) of children 12 months to <10 years of age received ≥2 MCV doses, while a large proportion of children remained under-vaccinated (34.0%, 95% CI: 28.0–40.0%) or unvaccinated (12.3%, 95% CI: 9.3–16.2%).

Conclusions

Implementation of the national measles campaign was a significant achievement towards measles elimination in India. In Jharkhand, campaign performance was below the target coverage of ≥90% set by the Government of India, and challenges in disseminating campaign messages were identified. Efforts towards increasing two-dose MCV coverage are needed to achieve the recently adopted measles elimination goal in India and the South-East Asia region.

A male person of 55 years with hypothyroidism, ascites and heart failure

Primary hypothyroidism is a common clinical condition but ascites caused by hypothyroidism is rare. Concurrent exudative ascites with heart failure even rarer. So its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a male person of 55 years with hypothyroidism with ascites and heart failure who responded well with thyroid hormone replacement therapy with complete resolution of ascites. Analyses of ascites from patients in this condition usually shows exudative ascites with high protein (>2.5gm/dl) and SAAG <1.1gm/dl. High index of suspicion is required to reach at such diagnosis. Though it is a rare but prognosis is excellent with replacement therapy.

Maternal periodontal disease as a significant risk factor for low birth weight in pregnant women attending a secondary care hospital in South India: a case-control study

CONTEXT

Periodontal disease (PD) is a common infection in the community; however, its relationship with low birth weight (LBW) has not been well-established.

AIMS

The aim was to determine the association between maternal PD and LBW.

SETTINGS AND DESIGN

A case-control (1:1) study.

MATERIALS AND METHODS

The study population comprised of women who delivered at the hospital during the study period (September 2011 to February 2012).Women between 18 and 35 years of age, who delivered singleton, live infants during study period with at least 18 teeth were enrolled. Those with pregnancy induced hypertension, gestational diabetes, blood-borne viral infections, periodontal treatment within the past 6 months and valvular heart disease were excluded. Control population was parity matched to the cases.

STATISTICAL ANALYSIS USED

Chi-square test, t-test and univariant and multivariant logistic regression were used to analyze various study findings, and level of significance was set at 5% (P<0.05).

RESULTS

PD was independently associated with LBW (odds ratio: 4.94, 95% confidence interval: 1.03-23.65, P=0.045). Additionally, conventional risk factors such as maternal height (P=0.029), secondary schooling (<8 years of schooling) (P=0.001), socio-economic status (P=0.046), type of family (joint) (P=0.008), number of ante-natal visits (P=0.028) and gestational age at birth (<37 weeks) (P=0.045) showed significant association with LBW.

CONCLUSIONS

There seems to be an association between PD and LBW independent of conventional risk factors. Women who had PD were 5 times more likely to deliver LBW infants.
