Background
Studies from Africa have suggested marked non-specific effects (NSEs) of routine vaccinations with effects on child survival. There have been few studies from Asia. We re-analyzed a study from Maharashtra, India, which had collected information on vaccinations during infancy and survival until 5 years of age.Design
4138 children born between 1987 and 1989 were visited at home every three months to collect information on nutritional status and vaccinations. Since nutritional status was a determinant of time to vaccinations, we adjusted for nutritional status in the analyzes of the association between vaccinations and mortality.Setting
45 contiguous villages in Shirur Administrative Block in Pune District.Main outcome measures
Mortality rate ratios (MRR) for different vaccination status groups.Results
The study area has male preferential treatment, but the female–male mortality ratio varied between age groups with different pre-dominant vaccines; it was high in the age group in which diphtheria–tetanus–pertussis (DTP) vaccine predominates and low in the age group in which measles vaccine (MV) is given. Children who followed the WHO recommended schedule of first BCG and then DTP vaccination were vaccinated earlier than other children (p < 0.01). Two-thirds of the children had received BCG and DTP out-of-sequence, i.e. BCG and DTP simultaneously or BCG after DTP. Children who received BCG and DTP simultaneously or BCG as most recent vaccination had significantly lower mortality than children having DTP as the most recent vaccination, the mortality rate ratio being 0.15 (0.03–0.70).Conclusions
BCG out-of-sequence may be associated with lower mortality than DTP as the most recent vaccination. Given the public health implications, this possibility should be tested in randomized trials. Excess female mortality may also be related to vaccination policy. 相似文献2.

The Middle‐East and Africa Influenza Surveillance Network (MENA‐ISN), established in 2014, includes 15 countries at present. Country representatives presented their influenza surveillance programmes, vaccine coverage and influenza control actions achieved, and provided a list of country surveillance/control objectives for the upcoming 3 years. This report details the current situation of influenza surveillance and action plans to move forward in MENA‐ISN countries. Data were presented at the 8th MENA‐ISN meeting, organized by the Mérieux Foundation that was held on 10‐11 April 2018 in Cairo, Egypt. The meeting included MENA‐ISN representatives from 12 countries (Algeria, Egypt, Jordan, Kenya, Lebanon, Libya, Morocco, Pakistan, Saudi Arabia, South Africa, Tunisia and United Arab Emirates) and experts from the Canadian Centre for Vaccinology, and the World Health Organization. Meeting participants concluded that influenza remains a significant threat especially in high‐risk groups (children under‐5, elderly, pregnant women and immunosuppressed individuals) in the MENA‐ISN region. Additional funding and planning are required by member countries to contain this threat. Future meetings will need to focus on creative and innovative ways to inform policy and initiatives for vaccination, surveillance and management of influenza‐related morbidity and mortality especially among the most vulnerable groups of the population. 相似文献

OBJECTIVE: To examine body size and fat measurements of babies born in rural India and compare them with white Caucasian babies born in an industrialised country. DESIGN: Community-based observational study in rural India, and comparison with data from an earlier study in the UK, measured using similar methods. SUBJECTS: A total of 631 term babies born in six rural villages, near the city of Pune, Maharashtra, India, and 338 term babies born in the Princess Anne Hospital, Southampton, UK. MEASUREMENTS: Maternal weight and height, and neonatal weight, length, head, mid-upper-arm and abdominal circumferences, subscapular and triceps skinfold thicknesses, and placental weight. RESULTS: The Indian mothers were younger, lighter, shorter and had a lower mean body mass index (BMI) (mean age, weight, height and BMI: 21.4 y, 44.6 kg, 1.52 m, and 18.2 kg/m(2)) than Southampton mothers (26.8 y, 63.6 kg, 1.63 m and 23.4 kg/m(2)). They gave birth to lighter babies (mean birthweight: 2.7 kg compared with 3.5 kg). Compared to Southampton babies, the Indian babies were small in all body measurements, the smallest being abdominal circumference (s.d. score: -2.38; 95% CI: -2.48 to -2.29) and mid-arm circumference (s.d. score: -1.82; 95% CI: -1.89 to -1.75), while the most preserved measurement was the subscapular skinfold thickness (s.d. score: -0.53; 95% CI: -0.61 to -0.46). Skinfolds were relatively preserved in the lightest babies (below the 10th percentile of birthweight) in both populations. CONCLUSIONS: Small Indian babies have small abdominal viscera and low muscle mass, but preserve body fat during their intrauterine development. This body composition may persist postnatally and predispose to an insulin-resistant state. 相似文献

Objective
To assess the effectiveness of micronutrient powder (MNP) supplementation in reducing anemia levels in children aged 6 mo to 6 y in India.Methods
Sixty sachets of MNP (Sprinkles Plus) were administered flexibly over a 4 mo period to 17,124 children at anganwadi centers or at home through Integrated Child Development Services (ICDS). Compliance was monitored using compliance cards and an assessment of mother’s recall at post-intervention survey. Hemoglobin was measured in separate random samples of 1,786 children before and 1,782 children after MNP supplementation.Results
Mean compliance rate was estimated at 56.4 % (based on mother’s recall) and 91.7 % (based on compliance cards) for children who received MNP at home. Mean compliance was 96.9 % (based on compliance cards) for children who received MNP at anganwadis. A significant reduction in anemia (50 % to 33 % in boys; p-value?<?.000; 47.4 % to 34.2 % in girls) was seen following MNP supplementation.Conclusions
Integration of a flexibly administered MNP supplementation into the ICDS is effective in reducing and treating anemia in children 6 mo to 6 y age. 相似文献7.

This study analyzed the effectiveness of active case detection (ACD) for new visceral leishmaniasis (VL) cases. ACD detection was carried out using house to house screening in Bangladesh and India and by neighborhood screening around index cases in Nepal. The percent increase of new VL cases through ACD compared to PCD was 6.7–17.1% in India; 38.8% in Nepal; and 60% in Bangladesh. The screening effort was high in India and Bangladesh (house to house screening) compared to Nepal (index case screening). The additional cost per new VL case detected varied: $50 to $106 in India; $172 in Bangladesh; $262 in Nepal depending on the type of screening staff, transport and training costs. The estimated annual VL incidence in the ACD arm ranged from 315–383 in India; 109 in Bangladesh, and 43 per 100,000 in Nepal. The additional effort and cost rises as disease incidence declines or PCD improves. 相似文献

Objective To compare the results obtained from 26 proxy indicators of domestic hand‐washing practices with those obtained from direct, ‘structured’ observation of hand‐washing in a sample of 387 households and to assess the potential of these indicators for use in the evaluation of hygiene promotion campaigns. Methods Fieldwork in rural India between February 2005 and April 2006. Household‐level data on hand‐washing practices and the availability of soap and water were collected by structured observation, questionnaire survey, pocket voting, hand‐wash demonstration and environmental check. Between them these techniques produced 27 binary indicators of hand‐washing practices, each of which was used to classify households as ‘hand‐washing’ or ‘non‐hand‐washing. To assess the extent to which household classification based on each of 26 proxy indicators concurred with classification based on observation, we used the kappa statistic. The prevalence of households defined as ‘hand‐washing’ according to each indicator was compared statistically with the prevalence according to structured observations by testing for a significant difference between two proportions. Results Agreement between all the proxy indicators and the observation data was poor and all but two of the indicators produced estimates of hand‐washing prevalence that were significantly different from that resulting from observation. Conclusion Although some interventions may be able to use proxy indicators as a guide to the magnitude and direction of their impact, these indicators do not provide an accurate guide to the actual practice or prevalence of hand‐washing. Structured observation remains the best indicator of those tested. 相似文献

This study compares the immunogenicity and safety of a single dose of a new meningococcal A conjugate vaccine (PsA-TT, MenAfriVac™, Serum Institute of India Ltd., Pune) against the meningococcal group A component of a licensed quadrivalent meningococcal polysaccharide vaccine (PsACWY, Mencevax ACWY®, GSK, Belgium) 28 days after vaccination in Indian children. This double-blind, randomized, controlled study included 340 Indian children aged 2–10 years enrolled from August to October 2007; 169 children received a dose of PsA-TT while 171 children received a dose of PsACWY. Intention-to-treat analysis showed that 95.2% of children in PsA-TT group had a ≥4-fold response in serum bactericidal titers (rSBA) 28 days post vaccination as compared to 78.2% in the PsACWY group. A significantly higher rSBA GMT (11,209, 95%CI 9708–12,942) was noted in the PsA-TT group when compared to PsACWY group (2838, 95%CI 2368–3401). Almost all children in both vaccine groups had a ≥4-fold response in group A-specific IgG concentration but the IgG GMC was significantly greater in the PsA-TT group (89.1 μg/ml, 95%CI 75.5–105.0) when compared to the PsACWY group (15.3 μg/ml, 95%CI 12.3–19.2). Local and systemic reactions during the 4 days after immunization were similar for both vaccine groups except for tenderness (30.2% in PsA-TT group vs 12.3% in PsACWY group). None of the adverse events or serious adverse events was related to the study vaccines. We conclude that MenAfriVac™ is well tolerated and significantly more immunogenic when compared to a licensed polysaccharide vaccine, in 2-to-10-year-old Indian children. 相似文献
