Stagnating trends in complementary feeding practices in Bangladesh: An analysis of national surveys from 2004-2014.
Bangladesh has experienced steady socio-economic development. However, improvements in child growth have not kept pace. It is important to document complementary feeding (CF) practices-a key determinant of children's growth-and their trends over time. The study aims to examine trends in CF practices in children aged 6-23Â months using data from Bangladesh Demographic and Health Surveys conducted in 2004, 2007, 2011, and 2014. Multilevel logistic regression models were applied to identify independent predictors of four CF practice indicators among children 6-23Â months, namely, timely introduction of complementary foods, minimum meal frequency, minimum dietary diversity, and minimum acceptable diet. Introduction of complementary foods was achieved among 64-71% of children between 2004 and 2014. The proportion meeting minimum meal frequency increased from 2004 to 2007 (71-81%) and declined and held steady at 65% from 2011 to 2014. The proportion meeting minimum dietary diversity in 2011 and 2014 was low (25% and 28%), and so was minimum acceptable diet (19% and 20%). From 2007 to 2014, child dietary diversity decreased and the most decline was in the consumption of legumes and nuts (29% to 8%), vitamin A-rich fruits and vegetables (54% to 41%), and other fruits and vegetables (47% to 20%). Young child age (6-11Â months), poor parental education, household poverty, and residence in the Chittagong and Sylhet independently predicted poorer feeding practices. Dietary diversity and overall diet in Bangladeshi children are strikingly poor. Stagnation or worsening of feeding practices in the past decade are concerning and call for decisive policy and programme action to address inappropriate child feeding practices
Effect of Ignoring Eccentricity in Testing General Relativity with Gravitational Waves
Detections of gravitational waves emitted from binary black hole coalescences
allow us to probe the strong-field dynamics of general relativity (GR). One can
compare the observed gravitational-wave signals with theoretical waveform
models to constrain possible deviations from GR. Any physics that is not
included in these waveform models might show up as apparent GR deviations. The
waveform models used in current tests of GR describe binaries on quasicircular
orbits, since most of the binaries detected by ground-based gravitational-wave
detectors are expected to have negligible eccentricities. Thus, a signal from
an eccentric binary in GR is likely to show up as a deviation from GR in the
current implementation of these tests. We study the response of four standard
tests of GR to eccentric binary black hole signals with the forecast O4
sensitivity of the LIGO-Virgo network. Specifically, we consider two
parameterized tests (TIGER and FTI), the modified dispersion relation test, and
the inspiral-merger-ringdown consistency test. To model eccentric signals, we
use non-spinning numerical relativity simulations from the SXS catalog with
three mass ratios , which we scale to a redshifted total mass of
and luminosity distance of Mpc. For each of these mass
ratios, we consider signals with eccentricities of and at
Hz. We find that signals with larger eccentricity lead to very significant
false GR deviations in most tests while signals having smaller eccentricity
lead to significant deviations in some tests. For the larger eccentricity
cases, one would even get a deviation from GR with TIGER at
credibility at a distance of Gpc. Thus, it will be necessary to
exclude the possibility of an eccentric binary in order to make any claim about
detecting a deviation from GR.Comment: 16 pages, 6 figures, version accepted by PR
Educating and training a workforce for nutrition in a post-2015 world.
Nearly all countries in the world today are burdened with malnutrition, manifesting as undernutrition, micronutrient deficiencies, and/or overweight and obesity. Despite some progress, efforts to alleviate malnutrition are hampered by a shortage in number, skills, and geographic coverage, of a workforce for nutrition. Here, we report the findings of the Castel Gandolfo workshop, a convening of experts from diverse fields in March 2014 to consider how to develop the capacity of a global cadre of nutrition professionals for the post-2015 development era. Workshop participants identified several requirements for developing a workforce for nutrition, including an ability to work as part of a multisectoral team; communication, advocacy, and leadership skills to engage decision makers; and a set of technical skills to address future challenges for nutrition. Other opportunities were highlighted that could immediately contribute to capacity development, including the creation of a consortium to link global North and South universities, online training modules for middle managers, and practical, hands-on experiences for frontline nutrition workers. Institutional and organizational support is needed to enable workshop recommendations on education and training to be effectively implemented and sustained. The findings from the Castel Gandolfo workshop can contribute to the delivery of successful nutrition-relevant actions in the face of mounting external pressures and informing and attaining the forthcoming Sustainable Development Goals
Type 2 diabetes in adolescents and young adults
The prevalence of type 2 diabetes in adolescents and young adults is dramatically increasing. Similar to older-onset type 2 diabetes, the major predisposing risk factors are obesity, family history, and sedentary lifestyle. Onset of diabetes at a younger age (defined here as up to age 40 years) is associated with longer disease exposure and increased risk for chronic complications. Young-onset type 2 diabetes also affects more individuals of working age, accentuating the adverse societal effects of the disease. Furthermore, evidence is accumulating that young-onset type 2 diabetes has a more aggressive disease phenotype, leading to premature development of complications, with adverse effects on quality of life and unfavourable effects on long-term outcomes, raising the possibility of a future public health catastrophe. In this Review, we describe the epidemiology and existing knowledge regarding pathophysiology, risk factors, complications, and management of type 2 diabetes in adolescents and young adults
AOMH-MISO based PV-VCI irrigation system using ASCIM pump
This paper presents a step in microlevel photovoltaic (PV) summation technology for combining unsymmetrical PV modules with differences in specification and age, relocation on nonfertile land, or multilocation mounting by designing an add-on modular hardware interface to a multi-input single-output (MISO) dc bus, using an MISO controller employing a suitable maximum power point (MPP) tracker under partial shading/long distance/mismatching PV module conditions along with a sensor-less PV vector control inverter (PV-VCI) driving a three-phase asynchronous squirrel cage induction motor dedicated to irrigation, with the facility of autoconfiguration/autotuning at the beginning. A PV source gets automatically added/removed in a ramp profile in proportion to the load in steps, thus keeping on only when required, enabling high efficiency, minimum heating, and prolonged life as that of a PV module. The contribution includes a reduced PV energy cost per watt by 24.10%, improved return on investment by 27.48%, improved water discharge yield by 11.06%, and improved MPP tracker impact by 14.59% with 90.88% MISO system efficiency compared to a normal scheme
New-onset diabetes after transplantation - Role of oral glucose tolerance test for diagnosis and study of risk factors
To determine the role of the oral glucose tolerance test in the early detection of new-onset diabetes after transplantation (NODAT) and to compare the various risk factors and insulin kinetics in the transplant patients, we studied 41 live-related renal allograft recipients who were not diabetic before transplantation. Immunosuppression included triple drug therapy (cyclosporine, azathioprine and steroids) and rejection episodes were treated with methyl prednisolone (30 mg/kg IV × 3 days). All the study patients were subjected to an oral glucose tolerance test (OGTT) at Day 90 post-transplant and classified as having normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and NODAT as per the World Health Organization guidelines. Insulin levels were also determined at 0, ½ hour, 1 hour and 2 hours during OGTT. NODAT was noted in 29.2% of the study patients, IFG in 4.8% of the study patients and NGT in 65.8% of the study patients. All the groups had normal fasting plasma glucose, but higher than normal insulin levels, suggesting insulin resistance. The patients with overt NODAT had, in addition, low fasting insulin (insulin secretory defect). OGTT may be used for the early detection of NODAT. Although insulin resistance is detected in the majority of post-transplant patients, NODAT also reveals also an insulin secretory defect
Comparative evaluation of mouth rinsing with plain water and an antibacterial mouth rinse on salivary pH: A randomized clinical trial
Introduction: Salivary pH plays an important role in maintaining oral health and in particular affecting dental caries. Studies have confirmed the antibacterial beneficial effects of chlorhexidine on dental health by increasing salivary pH (changing acidic pH to more neutral pH). Water, the most precious/omnipresent liquid also bears an effect on salivary pH. Materials and Methods: A double-blind concurrent parallel study design was employed on 40 individuals to evaluate changes in salivary pH before and after having meals. The study participants were divided into two groups with 20 each in Group A (those who rinsed with plain water) and Group B (those who rinsed with Chlorhexidine) who were assessed for the pH before and after meals. Results: On intragroup comparison, it was found that the mean pH of Group A was 5.56 ± 1.83 while the mean pH of Group B was 6.48 ± 1.49 after meals, which was statistically nonsignificant at P = 0.09. Conclusion: Water has a beneficial effect on salivary pH and in turn oral health, which is comparable with a standard mouth rinse
