National immunization day to assess nutritional status of underfives in Chandigarh

Determinants of nutritional status among under-five children receiving Integrated Child Development Services (ICDS) in India

Background: Undernutrition is a significant public health problem and the leading risk factor for India's disease burden. Aim: To understand the determinants of nutritional status among under-five children receiving Integrated Child Development Services (ICDS) in India. Methods: The study used the National Family Health Survey-4 (2015-16) data. The analysis was carried out for under-five children who have availed of any ICDS services in the 12 months preceding the survey (n = 1,27,813). Stunting, wasting, and underweight were estimated following the World Health Organization guideline and used as the outcome variables. The binary logistic regression was conducted to examine the association of ICDS utilization and socioeconomic-demographic predictors with under-five children's nutritional status. STATA (V 13) was used for statistical analyses. Results: A sizable proportion of under-five children receiving any ICDS services suffer from undernutrition. The undernutrition prevalence varied considerably by socioeconomic and demographic characteristics. Logistic regression found an insignificant association of ICDS utilization with the nutritional status of under-five children. Children not immunized in ICDS centers were less likely to be stunted (OR: 0.93; P < 0.01), wasted (OR: 0.93; P < 0.01), and underweight (OR: 0.90; P < 0.01) than their counterparts. The child's age and gender, maternal education and nutrition status, wealth index, social group, region, residence, and region were significant determinants of undernutrition among ICDS beneficiaries. Conclusion: The study suggests the need to ensure all available services to children enrolled in the Anganwadi Center (AWC). The program should also emphasize feeding practices and educate parents about improving child health and nutrition.

Use of measles supplemental immunization activities (SIAs) as a delivery platform for other maternal and child health interventions: opportunities and challenges

Measles supplementary immunization activities (SIAs) offer children in countries with weaker immunization delivery systems like India a second opportunity for measles vaccination. They could also provide a platform to deliver additional interventions, but the feasibility and acceptability of including add-ons is uncertain. We surveyed Indian programme officers involved in the current (2010-2012) measles SIAs concerning opportunities and challenges of using SIAs as a delivery platform for other maternal and child health interventions. Respondents felt that an expanded SIA strategy including add-ons could be of great value in improving access and efficiency. They viewed management challenges, logistics, and safety as the most important potential barriers. They proposed that additional interventions be selected using several criteria, of which importance of the health problem, safety, and contribution to health equity figured most prominently. For children, they recommended inclusion of basic interventions to address nutritional deficiencies, diarrhoea and parasites over vaccines. For mothers, micronutrient interventions were highest ranked.

Toll-like receptors in brain abscess

Brain abscesses arise from a localized parenchymal infection, typically elicited by pyogenic bacteria such as Staphylococcus aureus. Despite improvements in detection and treatment strategies, brain abscesses continue to occur, with an increased prevalence in developing countries and immune-compromised patients. Adding to the seriousness of these infections is the recent emergence of antibiotic-resistant strains of bacteria, which are becoming more commonly associated with brain abscesses. Recent studies using a mouse experimental brain abscess model have revealed a complex role for Toll-like receptors (TLRs) in disease pathogenesis. Interestingly, TLR2 has limited impact on the innate immune response during the acute stage of brain abscess formation induced by S. aureus but influences adaptive immunity. In contrast, mice deficient in MyD88, a central adapter molecule for the majority of TLRs in addition to the IL-1R and IL-18R, demonstrate severe defects in innate immunity coupled with exaggerated tissue destruction. It is envisioned that understanding the roles for TLRs in both resident CNS glia as well as infiltrating immune cells will provide insights into how the immune response to bacterial infection can be tailored to achieve effective pathogen destruction without inducing excessive bystander damage of surrounding noninfected brain parenchyma. A discussion of recent findings in this field is presented along with outstanding questions and the concept of a pathogen-necrosis-autoantigen triad for the amplification of TLR signaling is introduced.

National Immunization Day: a strategy to monitor health and nutrition indicators

PROBLEM

To achieve the Millennium Development Goals it is necessary to set up low-cost, real-time monitoring systems which can provide feedback to managers and policy-makers in a timely fashion. The gold-standard approach for monitoring nutritional situations is to conduct household surveys. However, they are costly, time consuming and do not furnish information about smaller disaggregated units.

APPROACH

Brazil pioneered National Immunization Days (NIDs) in the 1980s, and later integrated them with vitamin A supplementation. This report discusses implementation of five large-scale Health and Nutrition Days (HNDs) using NIDs as a platform to monitor nutritional status and estimate coverage of health and social welfare services, including conditional cash transfer benefits.

LOCAL SETTING

Brazil is composed of 26 states, one federal district and 5564 municipalities, with around 18 million children under five years of age. It was decided that HNDs would be carried out among high-risk populations: children from the semi-arid north-eastern region; agrarian reform settlements; isolated rural black communities or quilombolas and municipalities of Amazonas state.

RELEVANT CHANGES

It was possible to draw inferences for almost 3 million children from different subgroups of underprivileged populations who had never before been studied in such detail, including state-level data.

LESSONS LEARNED

Implementation of large scale HNDs in conjunction with NIDs proved to be feasible in Brazil and resulted in data which are very relevant for policy-makers, obtained over a short period of time and at reasonably low cost. It is sensible to conclude that the experience reported here could be reproduced wherever NID coverage is very high.

Treatment and prevention of cerebrovascular disorders in children

Cerebrovascular disorders are an important cause of mortality and chronic morbidity in children. Ischemic stroke is more common than cerebral venous thrombosis and hemorrhagic stroke in children. Several medical disorders have been associated with stroke in children, and a thorough evaluation of underlying causes is needed to determine the best treatment and prevention strategy. The treatment and prevention of stroke in children is not well studied, and current recommendations are based on adult studies, nonrandomized trials, or expert opinion. Children with stroke require immediate, special attention and if possible should be stabilized and transferred to an institution that can offer pediatric neurovascular expertise and care. All children with stroke should be referred to or have their care managed by a pediatric neurologist. The treatment of stroke in adults is well studied, and when applicable this evidence should be considered in the treatment of children with stroke. Data from animal and adult stroke studies have demonstrated a benefit for the aggressive treatment of infection, fever, blood pressure, hypo/hyperglycemia, intracranial pressure, and seizures, and should be applied to children with stroke. The use of thrombolytic, antithrombotic, and antiplatelet therapies is based on adult studies, cohort studies, and/or expert opinion. Two consensus guidelines regarding the treatment of arterial ischemic stroke and cerebral venous thrombosis were recently published and recommend the use of anticoagulants or antiplatelet agents in the acute setting, depending on the underlying cause of stroke. The evidence for the primary prevention of stroke in children is restricted to sickle cell disease (SCD) and derived from the Stroke Prevention in Sickle Cell Study Project studies. Long-term chronic transfusion therapy to maintain hemoglobin S levels below 30% is indicated in children with SCD and intracranial stenosis. It has also been recently determined that chronic transfusion therapy should not be stopped in children with SCD and an increased risk for stroke. The recurrence rate of arterial ischemic stroke (AIS) in children ranges from 6% to 30% and is highest among children with recurrent transient ischemic attack, cardiac disease, arteriopathies, and metabolic and coagulation abnormalities. Recommendations for secondary prevention are based on adult studies and the underlying pathophysiology of the stroke. Antiplatelet therapy (aspirin 1-5 mg/kg/day) is recommended in most children with a history of AIS. Although there is minimal evidence to support its use in children, anticoagulation may be indicated in AIS associated with extracranial arterial dissection, prothrombotic disorders, cardiac disease, severe intracranial stenosis, and recurrent AIS while on antiplatelet therapy.

Cerebrovascular disorders in children

Cerebrovascular disorders are an important cause of mortality and chronic morbidity in children. International incidence rates for childhood stroke (ie, from 30 days to 18 years of age) have ranged from 1.3 to 13 per 100,000 children. Ischemic stroke is probably more common than hemorrhagic stroke in children. The clinical presentation of stroke in children varies according to age and location of the stroke. Over 100 risk factors for stroke in children have been reported, but in up to one third of cases no cause is identified. The management and prevention of stroke in children is not well studied and current recommendations are based on adult studies, nonrandomized trials, or expert opinion. Over half of children with stroke will develop lifelong cognitive or motor disability and up to one third will have a recurrent stroke. This review briefly describes the epidemiology, risk factors, evaluation, treatment, and outcome of stroke in children.

Mass supplementation of vitamin A linked to National Immunization Day

OBJECTIVE

Main objectives were to assess the feasibility of linking vitamin A delivery with National Immunization Days (NIDs) and to see the impact on xerophthalmia.

METHODS

An Intervention study of mass distribution of vitamin A solution was undertaken to control widespread xerophthalmia prevalent in children living in about 26 slums of Chandigarh in the year 2000. Two rounds of mass distribution of Vitamin A solution covering 27642 and 31762 children in 1-5 years of age in first and second rounds, respectively, were undertaken. The findings of second round and post evaluation after intervention are presented here. An additional team of two persons per pulse polio immunization (PPI) centre delivered age specific doses of vitamin A solution through 98 centres and operational problems were recorded. PPI staff provided the supervision and PPI tally sheets were used.

RESULTS

The programme achieved a vitamin A coverage rate of 99% in first round and 88% in second round. Only two parents refused vitamin A solution. No side effect or cases of toxicity due to vitamin A were reported by health institutions in the area or in a stratified random sample of 101 children. There was a significant decline (13.4%) in xerophthalmia after two rounds of mass distribution (P < .001). The strategy to deliver vitamin A was successfully integrated into NID's and appeared to achieve a significant decline in xerophthalmia.

CONCLUSION

Linking of vitamin A distribution with PPI could be a basis for launching similar initiatives in other areas of India and other countries where xerophthalmia is a public health problem.

Epidemiology of perinatal stroke

Perinatal stroke has become increasingly recognized, but the incidence is probably underestimated because of variation in the presentation, evaluation, and diagnosis. Based on estimates from population-based studies of infants with seizures, perinatal stroke occurs in approximately 1 in 4000 term births. Most perinatal strokes involve the middle cerebral artery and are caused by thromboembolism from an intracranial or extracranial vessel, the heart, or the placenta. Cardiac disorders, coagulation abnormalities, and infection are risk factors for stroke in the perinatal period. This article discusses the epidemiology of ischemic stroke occurring in the perinatal and neonatal period, including cerebrovascular events that are diagnosed during the perinatal period and those diagnosed retrospectively, when evidence of hemiparesis or postneonatal seizures leads to later evaluation and neuroimaging.

Rapid assessment and delivery of Vitamin A to slum children by using National Immunization Day in Chandigarh

This study was done with the objective to see the feasibility of using National Immunization Days (NIDs) for rapid assessment, and delivery of Vitamin A solution to about 27,600 children dwelling in 26 slums in Union Territory of Chandigarh. The assessment of Vitamin A deficiency (VAD) was done in a stratified random sample of 1304 children during third round of Intensified Pulse Polio Immunization (IPPI) and delivery of Vitamin A solution was done during fourth round of IPPI in 1999-2000 covering 27,642 children in the age group of 1-5 years. An additional team of two persons per centre delivered age specific doses of Vitamin A solution through 72 centres and operational problems were recorded. IPPI staff provided supervision and same tally sheets as of IPPI were used. The prevalence rate of VAD was 24.6%, with conjunctival xerosis, bitot's spot and corneal xerosis as 23.7%, 0.6% and 0.2% respectively. 27,275 (98.7%) children out of 27,642 were administered Vitamin A solution, with no major operational problem. Only five parents (0.01%) refused Vitamin A solution. No case of side effect or toxicity due to Vitamin-A was reported. The strategy to assess and deliver Vitamin A during NID's was found to be feasible and successful and could be a basis for launching similar initiatives in other areas of India and other countries where VAD is a public health problem.
