Dietary Vitamin A intakes among Pregnant Women Attending Antenatal Care in Health Facilities: As a connotation for the progress of vitamin A Deficiency in Dessie Town, North East Ethiopia

Abstract

Vitamin A plays important roles in vision, cellular differentiation, embryonic development, reproduction, growth, and the immune system. Women living in developing countries are at increased risk of undernutrition during pregnancy due to poverty, poor diet quality and quantity, and high fertility rate. Dietary quality and diversity reflect adequacy of vitamin A whereby reduce the risk of vitamin A deficiency. The aim of study was to determine adequacy of vitamin A among pregnant women attending antenatal care in health facilities of Dessie town, Ethiopia, January, 2017. Health facility-based cross-sectional study was conducted among 390 women that attended antenatal care in Dessie town. The 9 food groups from FAO based on 24hours dietary recall was used for data collection. Adequacy of vitamin A was determined from nutrient adequacy ratio after obtaining report of nutrient intake from food composition table version III and IV in terms of B carotene and retinol equivalent respectively, based on estimated average requirement recommendation of vitamin A, 370 RE/day for pregnant women. Multivariable Logistic regression analysis was done after dichotomizing the dependent variables.\n\nAdequacy of vitamin A among pregnant women was 41.8 % with an average nutrient adequacy ratio of 0.9. The mean dietary intake of vitamin A was 290.1g per day. The predictors for adequacy of vitamin A were high and medium women diversity score (AOR=2.92; CI: 1.50-5.70) and (AOR=1.87; CI: 1.11- 3.16).\n\nIn this study adequacy of vitamin A was low and affected by women dietary diversity score. Focusing on food based approaches especially educating pregnant women to diversify their diet is crucial to reduce their risk of vitamin a deficiency.

Impact of pterygium on the ocular surface and meibomian glands

PurposeTo analyze how ocular surface parameters correlate to pterygium and investigate the possible impact on tear film and meibomian glands.\n\nMethodswe investigated objective parameters of the ocular surface such as conjunctival hyperemia, tear film stability and volume, meibomian gland dysfunction, dry eye disease, corneal topography comparing healthy individuals and correlating with the pterygium clinical presentation.\n\nResultsA total of 83 patients were included. Corneal astigmatism induction was 2.65 {+/-} 2.52 D (0.4-11.8). The impact of pterygium on the ocular surface parameters compared to matched controls was seen in: conjunctival hyperemia (control 1.55{+/-}0.39/pterygium 2.14{+/-}0.69; p=0.0001), tear meniscus height (control 0.24{+/-}0.05 mm/pterygium 0.36{+/-}0.14mm; p 0.0002), meiboscore lower eyelid (control 0.29{+/-}0.64/pterygium 1.38{+/-}0.95; p 0.0001) and meiboscore upper eyelid (control 0.53{+/-}0.62/pterygium 0.98{+/-}0.75; p=0.0083). We found a high number of pterygium patients (88%) presented meibomian gland alterations. Interestingly, meibomian gland loss was coincident to the localization of the pterygium in 54% of the upper and 77% lower lids.\n\nConclusionPterygium greatly impacts on ocular surface by inducing direct alterations in the pattern of meibomian glands besides corneal irregularities, conjunctival hyperemia and lacrimal film alterations, inducing significant symptoms and potential signs of dysfunction.

Hydrology-informed metapopulation modeling of liver fluke transmission in the Lawa Lake complex of northeast Thailand

While hydrologic processes are intuitively understood to influence transmission dynamics of water-related diseases, limited research exists that explicitly links hydrologic and infectious disease data. In the case of the life cycle of liver flukes, hydrology influences several transmission processes that mediate infection risk for multiple hosts. Northeast Thailand is a hotspot for liver fluke transmission and has strong seasonal flooding patterns. A metapopulation model linking local hydrologic processes with transmission of the liver fluke Opisthorchis viverrini in a lake system in northeast Thailand was developed and parameterized using infection data from 2008-2016. A rainfall-runoff model and other hydrologic data were used to assess level of connectivity between villages and the influence of upstream communities on parasite distribution in the study area. Disease transmission was modeled with metapopulations representing six village clusters around the lake using known prevalence data from humans, cats and dogs, snails, and fish. The metapopulation model improved upon the single-village model in its match to historical data patterns for the six village clusters with the introduction of the new time-variable parameters. Results suggest there are three unique hydrologic-epidemiologic regimes within the Lawa Lake system in response to upstream watersheds and risk of overland flooding that contribute to risk for O. viverrini infection. While available data may be insufficient to specifically characterize exact transmission dynamics, the practical implications of such findings are the importance of addressing connectivity for any intermediate host-based intervention. Similar approaches using hydrologic data to assess the impacts of water on pathogen transmission dynamics and inform mechanistic disease transmission models could be applied across other water-related disease systems.

Towards a further understanding of measles vaccine hesitancy in Khartoum state, Sudan: A qualitative study

BackgroundVaccine hesitancy is one of the contributors to low vaccination coverage in both developed and developing countries. Sudan is one of the countries that suffers from low measles vaccine coverage and from measles outbreaks. For a further understanding of measles vaccine hesitancy in Sudan, this study aimed at exploring the opinions of Expanded Program on Immunization officers at ministries of health, WHO, UNICEF and vaccine care providers at Khartoum-based primary healthcare centers.\n\nMethodsQualitative data were collected using semi-structured interviews during the period January-March 2018. The topic list for the interviews was developed and analyzed using the framework \"Determinants of Vaccine Hesitancy Matrix\" that developed by the WHO-SAGE Working Group.\n\nFindingsThe interviews were conducted with 14 participants. The majority of participants confirmed the existence of measles vaccine hesitancy in Khartoum state. They further identified various determinants that grouped into three domains including contextual, groups and vaccination influences. The main contextual determinant as reported is the presence of \"anti-vaccination\"; who mostly belong to some religious and ethnic groups. Parents beliefs about prevention and treatment from measles are the main determinants of the group influences. Attitude of the vaccine providers, measles vaccine schedule and its mode of delivery were the main vaccine related determinants.\n\nConclusionMeasles vaccine hesitancy in Sudan appears complex and highly specific to local circumstances. To better understand the magnitude and the context-specific causes of measles vaccine hesitancy and to develop adapted strategies to address them, there is a need to investigate measles vaccine hesitancy among parents.
