Recent advances in microbial engineering approaches for wastewater treatment: a review.

In the present era of global climate change, the scarcity of potable water is increasing both due to natural and anthropogenic causes. Water is the elixir of life, and its usage has risen significantly due to escalating economic activities, widespread urbanization, and industrialization. The increasing water scarcity and rising contamination have compelled, scientists and researchers, to adopt feasible and sustainable wastewater treatment methods in meeting the growing demand for freshwater. Presently, various waste treatment technologies are adopted across the globe, such as physical, chemical, and biological treatment processes. There is a need to replace these technologies with sustainable and green technology that encourages the use of microorganisms since they have proven to be more effective in water treatment processes. The present review article is focused on demonstrating how effectively various microbes can be used in wastewater treatment to achieve environmental sustainability and economic feasibility. The microbial consortium used for water treatment offers many advantages over pure culture. There is an urgent need to develop hybrid treatment technology for the effective remediation of various organic and inorganic pollutants from wastewater.

Warm antibody hemolytic anemia-a rare presentation of neonatal lupus.

Neonatal lupus erythematosus (NLE) affects 1%-2% pregnant females with autoimmunity. An infant presented with steroid refractory hemolytic anemia as a manifestation of NLE. A trial of withholding breastfeeding had a transient response, but infant was eventually put on cyclosporin therapy to control the hemolysis. Now he is thriving well and transfusion free.

Impact of community-based mitanin programme on undernutrition in rural Chhattisgarh State, India.

BACKGROUND: Community health workers known as mitanins undertook family-level counseling and mobilized the community to improve coverage of maternal and child health services in the state of Chhattisgarh, India. The Nutrition Security Innovation (NSI) project was launched in selected blocks with additional inputs for promoting appropriate complementary feeding practices and disseminating information on Public Distribution System (PDS) entitlement. Within 3 years of project implementation, all NSI inputs in the project group (PG) were scaled up in the entire state. OBJECTIVE: To study the impact of interventions on nutritional status in PG and non-NSI comparison group (CG) blocks. METHODS: Quasi-experimental mixed methods were used. The sample consisted of 3,626 households with children under 3 years of age and 268 mitanins. RESULTS: A ratio of 1 mitanin per 250 to 500 population was effective. The coverage of exclusive breastfeeding, timely introduction of complementary feeding, DPT immunization, and antenatal care services was more than 70%. The PDS reached almost 90% of beneficiaries. In both the PG and the CG, one-third of children were undernourished, with one-quarter of children undernourished by 6 months of age. The prevalence of low birthweight was over 40%, and half of all women were undernourished. The estimated annual average reduction rate (AARR) for the entire state was estimated to be 4.22% for underweight and 5.64% for stunting. CONCLUSIONS: The strategy of Mitanin Programme in the Indian state of Chhattisgarh was unique with the implementation of direct nutrition actions being spearheaded by the health sector and community health volunteers in coordination with the Integrated Child Development Services (ICDS) and the Public Distribution System (PDS). The highest priority was given to interventions in the first 92 weeks of life. This implied ensuring frequent counseling and delivery of services through the entire pregnancy period and continued follow up till the children were at least one year of age. An accelerated decrease in the annual rate of reduction of underweight and stunting was observed. The emerging findings point to the significant contributions that can be made by the National Rural Health Mission (NRHM) in India by involvement of community health volunteers known as Accredited Social Health Activists (ASHAs) towards reducing the persistent problem of undernutrition in the country.

Impact of omega-6 fatty acids on cardiovascular outcomes: A review.

Poly unsaturated fatty acids (PUFAs) have usually been associated with beneficial health effects on early life and later life disease such as cardiovascular diseases (CVD). Emerging evidence, however, suggests that PUFA species (n-3, n-6) have differential health effects. N-6 PUFAs, in particular, have sparked a scientific debate regarding their role in human physiological processes. Current dietary recommendations for n-6 fatty acids have been based on animal studies, insufficient epidemiological evidence and mixed PUFA interventions, therefore, require reconsideration. This review has analyzed human epidemiological and interventional studies, published in the last five years, focusing on n-6 fatty acids' impact on CVD outcomes (CVD events, blood lipids, blood pressure, inflammation, oxidative stress/atherosclerosis). The evidence is mixed, with differential effects within the n-6 fatty acid series. These outcomes are also dependent on ethnicity and background health status. Further, data from developing countries are sparse, thus, well designed intervention trials and population based studies in developing country settings on specific n-6 fatty acid intake and health effects are desired.
