Food Environments, Food Security, and Household Food Availability of Circular Migrant Families: A Mixed-Methods Study Among Brick Kiln Laborers in Bihar, India.

BACKGROUND: Circular migration is the dominant pattern of movement in India and is a livelihood strategy used by many food insecure rural households. Repeated shifts in food environments have important implications on household food security and dietary patterns but have not been studied. OBJECTIVE: To explore differences in the food environment, food security, and food availability between home and destination spaces. METHODS: Mixed-methods research was conducted among circular migrant families working and residing on brick kilns in the state of Bihar. Utilizing stratified cluster sampling, 2 rounds of cross-sectional data were collected from 2564 families. Additionally, 25 in-depth interviews were conducted with circular migrant parents, kiln owners, and labor contractors. The Food Insecurity Experience Scale was validated for use in our study population. Bivariate analyses were conducted to estimate the association of food insecurity with sociodemographic variables. Qualitative data were analyzed using descriptive thematic methods. RESULTS: Seventy percent of respondents utilized at least one nonmarket source of food at the origin; at the destination, sources of food were limited to the private market. Despite higher food prices at the destination, perceived food affordability was higher during periods of migration, resulting in improved food security. Tubers, rice, and wheat were typically available in the household daily, whereas fruits, eggs, and dairy were typically unavailable during the week. CONCLUSIONS: Circular migration can enable short-term food security by improving food affordability. Policy frameworks must address the root causes of chronic food insecurity, especially among rural-to-rural circular migrant families.

Early life migration and undernutrition among circular migrant children: An observational study in the brick kilns of Bihar, India.

BACKGROUND: India holds the world's largest burden of chronic and acute child undernutrition. Poverty and systemic inequities are basic causes of undernutrition that also drive households to engage in circular migration for livelihood. Short-term, temporary movement of the whole family, including young children, is common; yet, the nutritional implications of recurrent movements beginning in early life has not been studied. We sought to estimate the association of repeat and early life migration with stunting and wasting outcomes among circular migrant children under three. METHODS: Using a stratified cluster design, we conducted two waves of primary data collection among 2564 randomly selected circular migrant children under three years of age temporarily residing across 1156 brick kilns in Bihar, India. We conducted multilevel modeling to estimate the association of the number of migration episodes and age at first migration with stunting (<-2 standard deviations (SD) height-for-age z scores (HAZ)) and wasting (<-2 SD weight-for-height z-scores (WHZ)) and examined the determinants of nutrition status among migrant children, including diet, illness, food security and the health environment. RESULTS: The overall prevalence of stunting was 51.6%. Among children who were either born during migration or first migrated before six months of age, those who experienced multiple episodes of migration were more likely to be stunted compared to those who migrated once (adjusted odds ratio (aOR) = 2.10; 95% confidence interval (CI) = 1.30-3.41). Children were over three times as likely to be wasted in the summer compared to the winter (aOR = 3.28; 95% CI = 2.68-4.01); in the summer, the overall prevalence of wasting was 38.8%. Public health access indicators such as interaction with frontline health workers at the destination was low (5.3%), whereas feeding indicators such as exclusive breastfeeding among 0-5 months was high (81.1%). CONCLUSIONS: Policy efforts should ensure continuity of social protection and welfare entitlements between home and destinations for circular migrant families, with an explicit focus on rural-to-rural movement.

Hybrid ontology for semantic information retrieval model using keyword matching indexing system.

Ontology is the process of growth and elucidation of concepts of an information domain being common for a group of users. Establishing ontology into information retrieval is a normal method to develop searching effects of relevant information users require. Keywords matching process with historical or information domain is significant in recent calculations for assisting the best match for specific input queries. This research presents a better querying mechanism for information retrieval which integrates the ontology queries with keyword search. The ontology-based query is changed into a primary order to predicate logic uncertainty which is used for routing the query to the appropriate servers. Matching algorithms characterize warm area of researches in computer science and artificial intelligence. In text matching, it is more dependable to study semantics model and query for conditions of semantic matching. This research develops the semantic matching results between input queries and information in ontology field. The contributed algorithm is a hybrid method that is based on matching extracted instances from the queries and information field. The queries and information domain is focused on semantic matching, to discover the best match and to progress the executive process. In conclusion, the hybrid ontology in semantic web is sufficient to retrieve the documents when compared to standard ontology.

Unexpected post-mortem diagnosis of systemic sclerosis presenting as pneumatosis intestinalis: revised diagnostic criteria and medicolegal implications.

Systemic sclerosis is a challenging diagnosis for clinicians and pathologists alike due to its protean manifestations and often insidious onset, particularly in cases without significant titres of auto-antibodies. Herein we present a case of a female in her sixties who died rapidly following a clinical diagnosis of pneumatosis intestinalis and respiratory failure of unclear etiology. Recently revised clinical diagnostic criteria were applied to the clinical history and postmortem findings to reach an unexpected diagnosis of systemic sclerosis. The diagnosis of systemic sclerosis at autopsy has important medicolegal implications largely related to premature death due to delayed treatment or poor post-operative outcome. Moreover, familial clustering of this disease underscores the importance of maintaining a high index of suspicion in the postmortem setting.

Nanocrystalline silver dressing and subatmospheric pressure therapy following neoadjuvant radiation therapy and surgical excision of a feline injection site sarcoma.

UNLABELLED: CLINICAL SUMMARY: This is the first clinical report of use of a combination of nanocrystalline silver and subatmospheric pressure therapy to treat a resistant wound infection, following tumour removal and radiation therapy, in a difficult-to-manage surgical site in a cat. PRACTICAL RELEVANCE: The therapy was well tolerated and the authors suggest it is a valid treatment protocol for management of non-healing or infected wounds in the cat.

Ovine placental eluate immunoglobulins recognise isologous and third party acid-treated trophoblast microvesicle antigens in vitro.

Placental microvesicles were prepared from ovine placentae and immunoglobulins eluted with 0.5 M glycine buffer pH 2.5. The ability of eluate immunoglobulins to re-associate with isologous (self) and third party acidified microvesicles was tested by ELISA. Ovine placental immunoglobulins re-associated with isologous and third party acidified microvesicles suggesting that at least 2 types of antigenic epitopes I and II maybe expressed on the ovine placentae. Type I antigens may be present on placentae of all ovines while type II epitopes may be paternally derived, hence unique to each pregnancy. Analysis by SDS PAGE revealed the heavy and light chains of IgG at 57 and 27 kDa, respectively, together giving a relative molecular weight of 158 kDa. Results suggest that immunoglobulins produced to placental microvesicle antigens may be directed to some but not all antigenic epitopes expressed on the trophoblast, possibly defining a mechanism by which the foetus evades maternal immunological rejection.
