BackgroundMalaria continues to be a major cause of infectious disease mortality in tropical regions. However, deaths from malaria are most often not individually documented, and as a result overall understanding of malaria epidemiology is inadequate. INDEPTH Network members maintain population surveillance in Health and Demographic Surveillance System sites across Africa and Asia, in which individual deaths are followed up with verbal autopsies.ObjectiveTo present patterns of malaria mortality determined by verbal autopsy from INDEPTH sites across Africa and Asia, comparing these findings with other relevant information on malaria in the same regions.DesignFrom a database covering 111,910 deaths over 12,204,043 person-years in 22 sites, in which verbal autopsy data were handled according to the WHO 2012 standard and processed using the InterVA-4 model, over 6,000 deaths were attributed to malaria. The overall period covered was 1992–2012, but two-thirds of the observations related to 2006–2012. These deaths were analysed by site, time period, age group and sex to investigate epidemiological differences in malaria mortality.ResultsRates of malaria mortality varied by 1:10,000 across the sites, with generally low rates in Asia (one site recording no malaria deaths over 0.5 million person-years) and some of the highest rates in West Africa (Nouna, Burkina Faso: 2.47 per 1,000 person-years). Childhood malaria mortality rates were strongly correlated with Malaria Atlas Project estimates of Plasmodium falciparum parasite rates for the same locations. Adult malaria mortality rates, while lower than corresponding childhood rates, were strongly correlated with childhood rates at the site level.ConclusionsThe wide variations observed in malaria mortality, which were nevertheless consistent with various other estimates, suggest that population-based registration of deaths using verbal autopsy is a useful approach to understanding the details of malaria epidemiology.
BackgroundMortality from external causes, of all kinds, is an important component of overall mortality on a global basis. However, these deaths, like others in Africa and Asia, are often not counted or documented on an individual basis. Overviews of the state of external cause mortality in Africa and Asia are therefore based on uncertain information. The INDEPTH Network maintains longitudinal surveillance, including cause of death, at population sites across Africa and Asia, which offers important opportunities to document external cause mortality at the population level across a range of settings.ObjectiveTo describe patterns of mortality from external causes at INDEPTH Network sites across Africa and Asia, according to the WHO 2012 verbal autopsy (VA) cause categories. DesignAll deaths at INDEPTH sites are routinely registered and followed up with VA interviews. For this study, VA archives were transformed into the WHO 2012 VA standard format and processed using the InterVA-4 model to assign cause of death. Routine surveillance data also provide person-time denominators for mortality rates.ResultsA total of 5,884 deaths due to external causes were documented over 11,828,253 person-years. Approximately one-quarter of those deaths were to children younger than 15 years. Causes of death were dominated by childhood drowning in Bangladesh, and by transport-related deaths and intentional injuries elsewhere. Detailed mortality rates are presented by cause of death, age group, and sex.ConclusionsThe patterns of external cause mortality found here generally corresponded with expectations and other sources of information, but they fill some important gaps in population-based mortality data. They provide an important source of information to inform potentially preventive intervention designs.
Rotavirus is the major cause of severe diarrhea in children under 5 years old in developed and developing countries. Since improvements in sanitation and hygiene have limited impact on reducing the incidence of rotavirus diarrhea, implementation of a vaccine will be a better solution. We conducted an observational study to determine the disease burden and to identify the genotype of circulating rotavirus in Indonesia. Hospitalized children due to acute diarrhea were enrolled from four teaching hospitals in Indonesia. Stool samples were collected based on WHO protocol and were tested for the presence of group A rotavirus using enzyme immunoassay. Then, rotavirus positive samples were genotyped using RT-PCR. Fisher’s Exact tests, Chi square tests and logistic regression were performed to determine differences across hospital and year in rotavirus prevalence and genotype distribution. There were 4235 samples from hospitalized children with diarrhea during 2006, 2009 and 2010. Among them, the rotavirus positive were 2220 samples (52.42 %) and incidence rates varied between hospitals. The G1P[8], G1P[6], and G2P[4] were recognized as the dominant genotypes circulating strains in Indonesia and the proportion of predominant strains changed by year. Our study showed the high incidence of rotavirus infection in Indonesia with G1P[8], G1P[6], and G2P[4] as the dominant strains circulating in Indonesia. These results reinforce the need for a continuing surveillance of rotavirus strain in Indonesia.
SummaryConsanguineous marriages in two population samples, one rural and one urban, from Swat (Pakistan) were studied. The frequency of consanguineous marriages was found to be 37·13% and 31·11%, and mean inbreeding coefficients were calculated as 0·0168 and 0·0162, for the rural and urban populations respectively. The most frequent type of marriage was between first cousins, in both samples. Among first cousin marriages, those with father's brother's daughter were predominant. Mean inbreeding coefficient was higher for higher socioeconomic groups in both samples. Differences by ethnic and educational groups were also found. Contrary to previous studies, a significant increase in the incidence of consanguineous marriages over the years has been observed. The incidence of premature mortality was significantly higher only in the offspring of first cousin marriages. Significantly higher incidence of morbidity in the offspring of consanguineous marriages was also observed.
Background Regardless of the disease burden of human papillomavirus (HPV), the vaccine has not been included in the Indonesia National Immunization Program. Since 2017 there was a demonstration program of the HPV vaccination in Yogyakarta Province. This vaccine was given free to female primary school students in the 5th and 6th grades (11–13 years old). This study aimed to assess whether a structured-educational intervention focus on HPV increases the parental awareness, knowledge, and perceptions toward HPV and the vaccine acceptability. Methods We conducted a pre-post structured-educational intervention study from July to August 2017 before the implementation of the HPV vaccination demonstration program, in Kulon Progo District, Yogyakarta Province, Indonesia. Parents of female primary school students grades 5th and 6th were selected using a school-based proportional random sampling. A pediatric resident provided a structured-educational intervention, which consists of the burden and risk of HPV disease, as well as the benefit and safety of the vaccine. Parents were required to complete validated self-administered questionnaires before and after the structured-educational intervention. Results A total of 506 parents participated. Before receiving the structured-educational intervention, parents’ awareness of HPV infection and the vaccines were low. Only 49.2% of parents had heard HPV infection, and 48.8% had heard about the vaccine. After the structured-educational intervention, there were significant improvements in parent’s awareness, knowledge, and perceptions of HPV infection, cervical cancer, and HPV vaccination (all p < 0.001). HPV vaccine’s acceptability increased from 74.3 to 87.4% (p < 0.001). There was a significant correlation between increasing HPV vaccine acceptability with the improvement of awareness, knowledge, and perception toward HPV infection, cervical cancer and HPV vaccination (r = 0.32 to 0.53, p < 0.001). After the structured-educational intervention, better knowledge and positive perceptions of HPV vaccination were predictive of HPV vaccine’s acceptability with OR 1.90 (95%CI:1.40–2.57) and OR 1.31(95%CI,1.05–1.63), respectively. Conclusions A structured-educational intervention may improve parental awareness, knowledge, and perceptions toward HPV and the acceptability of the vaccine. Further study, a randomized control trial with longer follow-up are needed to evaluate the long-term and actual effectiveness of improving parents’ knowledge, perceptions and HPV vaccine acceptability.
Grebe-type chondrodysplasia exhibits a severe form of limb shortening and appendicular bone dysmorphogenesis. Here we report a family with seven males and six females who inherited the disorder in an autosomal recessive fashion. While the carrier parents did not exhibit any apparent skeletal abnormalities, all affected patients had a similar phenotype with unaffected axial and craniofacial bones. Since mutations in the cartilage-derived morphogenetic protein 1 (CDMP1) gene have been reported in similar acromesomelic chondrodysplasias, we examined genomic DNA from affected and normal subjects for possible mutations in CDMP1. In affected subjects, an insertion of a C at nucleotide 297 of the coding sequence was discovered. This insertion produced a shift in the reading frame at amino acid residue 99, causing premature termination of the polypeptide six amino acids downstream. DNA samples from 41 control subjects did not show this mutation. The truncated CDMP1 protein in these subjects is predicted to cause a total loss of its signaling function. The present report confirms that CDMP1 plays an important role in the regulation of axial bone growth during development and suggests that its absence does not impair other developmental processes.
