The goal of this study was to obtain representative Kenyan data on the point prevalence of acute otitis media (AOM) and its sequelae (otitis media with effusion [OME] and chronic suppurative otitis media [CSOM]), a major cause of preventable hearing loss in children in developing countries. In Africa, there are limited studies on the prevalence of AOM and its sequelae in children. Study subjects were children aged 2 to 15 years and were enrolled from randomly selected preprimary and primary schools. After parental or guardian consent, subjects had a questionnaire administered, otoscopy and tympanometry were done, and audiometry was performed on those with ear problems detected on these examinations. A total of 9825 (75%) children was from rural schools. The prevalence of CSOM was 15 of 1000, OME was 15 of 1000, and AOM was 7 of 1000 children. Rural Rift Valley schoolchildren had the highest prevalence of CSOM (24 of 1000) compared with other regions (12 of 1000; P < .0001). Ear discharge occurred before 3.5 years in 50% of 901 children with ear discharge. A history of ear discharge was associated with abnormal tympanograms (odds ratio [OR], 11.9-19.2) and mild-to-severe hearing loss (OR, 21.6-38.6), even in children without ear disease (OR, 10.7-24.4). The burden of AOM sequelae in Kenyan preschool and schoolchildren is significant, and it occurs mostly in the first 4 years of life. By preventing early recurrent AOM, pneumococcal vaccination might partly avert nonreversible sequelae. © The Author 2015.

Since 2011, cohorts of schoolchildren in regions bordering Lake Victoria in Kenya and Tanzania have been investigated for morbidity caused by Schistosoma mansoni infection. Despite being neighbouring countries with similar lifestyles and ecological environments, Tanzanian schoolchildren had lower S. mansoni prevalence and intensity and they were taller and heavier, fewer were wasted and anaemic, and more were physical fit compared to their Kenyan peers. The aim of the present study was to evaluate whether diet and school-related markers of socioeconomic status (SES) could explain differences in morbidity beyond the effect of infection levels. Parasitological and morbidity data from surveys in 2013-2014 were compared with information on diet and school-related markers of SES collected in 2015 using questionnaires. A total of 490 schoolchildren (163 Kenyans and 327 Tanzanians) aged 9-11 years provided data. A higher proportion of Tanzanian pupils (69.4%, 95% CI: 64.3-74.5) knew where to wash hands after toilet visits compared to Kenyan pupils (48.5%, 95% CI: 40.9-56.1; P<0.0005). Similar proportions of children in the two countries ate breakfast, lunch and dinner, but the content of the meals differed. At all three meals, a higher proportion (95% CI) of Tanzanian pupils consumed animal proteins (mostly fish proteins) compared to their Kenyan peers (35.0% (28.3-41.7) vs. 0%; P<0.0005 at breakfast; 69.0% (63.9-74.1) vs. 43.6% (35.8-51.4); P<0.0005 at lunch; and 67.2% (62.1-72.3) vs. 53.4% (45.8-61.0); P = 0.003 at dinner). Multivariable analyses investigating risk factors for important morbidity markers among individuals revealed that after controlling for schistosome and malaria infections, eating animal proteins (fish) and knowing where to wash hands after toilet visits were significant predictors for both haemoglobin levels and physical fitness (measured as VO2 max). These results suggest that the differences in morbidity may be affected by factors other than S

The purpose of this study was to determine the average angular dimensions that define the normal soft-tissue facial profiles of black Kenyans and Chinese and compare them with each other and with values proposed for whites. Standardized facial profile photographs, taken in natural head position, of 177 black Kenyans and 156 Chinese with normal occlusion and well-balanced faces were analyzed for 12 angular parameters. Two-sample t-tests were used to determine sex and racial differences. Kenyan and Chinese averages were compared with proposed white values using 1-sample t-tests. Eight parameters in Kenyans and 7 in Chinese showed sex differences. All angles, except for facial convexity, nasal dorsum, and inferior facial height, were different between Kenyans and Chinese. Kenyan and Chinese averages for all parameters were different from proposed white average, except for facial convexity. Nasolabial and mentolabial angles showed large individual variability and racial differences. The study demonstrated many differences in average angular measurements of the facial profiles of black Kenyans, Chinese, and white standards. Orthodontists, maxillofacial and plastic surgeons, and other clinicians working in the craniofacial region should bear these in mind when setting aesthetic treatment goals for patients of different races. Mean values from this study can be used for comparison with similar records of subjects with same ethnicity.
The attitudes of Kenyan in-school adolescents toward sexual autonomy.

2010-03-01
This was a cross-sectional study to examine the attitudes of Kenyan in-school adolescents towards premarital sex, unwanted pregnancies/abortions and contraception. Data collection was undertaken using a structured questionnaire. Kenyan in-school adolescents have conservative attitudes toward premarital sex, disagreeing that adolescent boy and girls should be left alone to satisfy their sexual needs. The girls had the view that boys have uncontrollable sexual appetites. With regards to unwanted pregnancies, the majority of the respondents disagreed with allowing abortions for pregnant school girls while they agreed that a pregnant school girl should be allowed to return to school. However, the majority of the girls held the view that a school boy who had impregnated a school girl should be expelled from school. The attitudes of the respondents to contraception were also largely conservative. The conservative attitudes of the respondents conflicts with the findings of high levels of unsafe sex and reproductive ill-health among Kenyan adolescents. There is need to help Kenyan in-school adolescents to develop more realistic attitudes toward sexuality in order to improve their reproductive health.

Under trial conditions insecticide-treated nets have been shown to provide significant clinical and mortality protection under a range of malaria transmission intensity conditions. There are, however, few operational impact data, notably in very intense transmission conditions. This study, reports on malaria infection among Kenyan schoolchildren living in areas of intense malaria transmission and their reported use of insecticide-treated bed nets. 5188 children in 54 schools were randomly sampled from seven counties surrounding Lake Victoria between May and June 2014. A questionnaire was administered to schoolchildren in classes 2-6 on the use of a long-lasting, insecticide-treated net (LLIN) the night before the survey and provided a single blood sample for a rapid diagnostic test for malaria infection. Analysis of the impact of insecticide-treated net use on malaria prevalence was undertaken using a multivariable, mixed effects, logistic regression at 95% confidence interval (CI), taking into account hierarchical nature of the data and results adjusted for school clusters. The overall prevalence of malaria infection was 48.7%, two-thirds (67.9%) of the children reported using LLIN, 91.3% of the children reported that their households own at least one LLIN and the household LLIN coverage was 2.5 persons per one LLIN. The prevalence of infection showed variation across the counties, with prevalence being highest in Busia (66.9%) and Homabay (51.8%) counties, and lowest in Migori County (29.6%). Generally, malaria parasite prevalence differed between age groups and gender with the highest prevalence occurring in children below 7 years (50.6%) and males (52.2%). Adjusting for county and school, there was a significant reduction in odds of malaria infection among the schoolchildren who reported LLIN use the previous night by 14 % (aOR 0.86, 95% CI 0.74-0.98, P < 0.027). Malaria transmission continues to be high around Lake Victoria. Despite evidence of increasing

As part of its health education programme, the Irish Cancer Society sponsored studies of the smoking habits of Dublin schoolchildren in the late 1960s and early 1970s. It was decided to review the situation a decade later, and accordingly the Health Education Bureau, the Medico-Social Research Board and the Irish Cancer Society funded a survey of smokers among Dublin post-primary schoolchildren in 1981. The prevalance of smoking among schoolchildren is still at a high level, and the main change over the last 10 years has been the fact that girls have almost caught up with the boys. It was hard to evaluate the effect of health education over the decade. Although many of the `smoking' students wanted to give up smoking the reason was not long-term health. In fact, concentrating on the `cancer/shorten life' effects of smoking may be counterproductive and anti-smoking campaigns should perhaps stress the immediate benefits of giving up smoking-better breathing, increased ability for sport, saving of money, and so on.

[Importance for Cancer Education for Schoolchildren].
Tanaka, Hideo
2015-08-01
Since the cancer incidence rate is generally very low in individuals aged 10 to 40 years, social concern for cancer prevention education for schoolchildren is likely to be insufficient in Japan.This paper presents epidemiological evidence to stress the importance of preferable health perceptions and behaviors in schoolchildren for the prevention of tobacco-related cancer, abnormal body mass index-related cancer, and cervical cancer.To improve the effectiveness of cancer education for schoolchildren, it is important to monitor their health perceptions and behaviors at least until junior high school.When a goal is set for the reduction of cancer incidence, it takes a very long time (at least 50 years).Therefore, the vision regarding cancer education for schoolchildren should not be changed for at least 50 years, whereas the methods and contents should be revised appropriately.

Objetive: The aim of this study was to analyze possible horizontal transmission patterns of S. mutans among 6-7-yr-old schoolchildren from the same class, identifying genotypes and their diversity and relationship with caries disease status. Study Design: Caries indexes and saliva mutans streptococci and lactobacilli counts were recorded in 42 schoolchildren. Mutans streptococci colonies were identified by means of biochemical tests and all S. mutans strains were genotyped by arbitrarily primed polymerase chain reaction. A child was considered free of S. mutans when it could not be isolated in 3 samples at 1-week intervals. Results: S. mutans was isolated in 30 schoolchildren: 20 having one genotype and 10 two genotypes. Higher mutans streptococci and caries index values were found in those with two genotypes. Five genotypes were isolated in more than 1 schoolchild and one of these was isolated in 3 schoolchildren. Our results suggest that horizontal transmission may take place. Conclusion: Schoolchildren aged 6-7 yrs may be the source of mutual transmission of S. mutans. Key words:Streptococcus mutans, Horizontal transmission, AP-PCR, genotyping PMID:22143733

In 1991 the TIE (Telescopes in Education) Foundation provided schoolchildren with the ability to access professional observatory telescopes remotely. TIE has raised the profile of astronomy and science among schoolchildren. Since the initiation of this facility the TIE Foundation have spread their reach from one telescope in the US to many telescopes and many schools across the globe. The VTIE (Virtual Telescopes in Education) project was launched in 2001 to build on the success of TIE. The VTIE VLE (Virtual Learning Environment) provides a Web portal through which pupils can create a scientific proposal, retrieve astronomical images, and produce a scientific paper summarizing their learning experiences of the VTIE scientific process. Since the completion of the first formative evaluations of VTIE (which involved over 250 schoolchildren) it has been observed that the participating schoolchildren have had difficulty completing and understanding the practical imaging aspects of astronomical science. Our experimental observations have revealed that the imaging tools currently available to astronomers have not ported well to schools. The VTIE imaging tools developed during our research will provide schoolchildren with the ability to store, acquire, manipulate and analyze images within the VTIE VLE. It is hypothesized herein that the provision of exclusively child-centered imaging software components will improve greatly the children's empowerment within the VTIE scientific process. Consequentially the addition of fully integrated child-centered imaging tools will contribute positively to the overall VTIE goal to promote science among schoolchildren.

To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (P<.001), lack of anxiety (P=.048), and global self-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (P<.001), life satisfaction (P=.036), and global self-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

To investigate the change in uncorrected visual acuity (UCVA) among schoolchildren in Bonin Islands. UCVA of schoolchildren aged 6 to 14 years, was collected from reports of School Health Examination Surveys conducted from 1981 to 2012. The proportion of schoolchildren with poor UCVA in the Bonin Islands was compared with those in metropolitan Tokyo. The results in Bonin Islands were also divided into two groups, before- and after-1996 when terrestrial television broadcasting service has been started, and the data of those two groups were compared. The proportion of schoolchildren with poor UCVA in Bonin Islands was lower than that in Tokyo. Among the residents of Bonin Islands, the proportion of schoolchildren with UCVA of < 1.0 was higher in the after-1996 group than in the before- 1996 group, with a clear increase in schoolchildren with poor UCVA after 1996 (p < 0.01, Fisher's exact test), examined among the 4th grade of elementary school or above. After 1996, 26.6% of first graders at a public junior high school had poor UCVA of < 0.7, whereas before 1996 no such case could be detected. The present study revealed that the proportions of schoolchildren with poor UCVA in Bonin Islands was lower than that in Tokyo; but in the residents of Bonin Islands after 1996, the proportion of the schoolchildren with poor UCVA increased.

Data examining the characteristics of patients with frequent exacerbations of chronic obstructive pulmonary disease (COPD) and associated hospitalisations and mortality are scarce. Post-hoc analysis of the Prevention Of Exacerbations with Tiotropium in COPD (POET-COPD) trial, targeting exacerbations as the primary endpoint. Patients were classified as non-, infrequent, and frequent exacerbators (0, 1, or ≥ 2 exacerbations during study treatment), irrespective of study treatment. A multivariate Cox regression model assessed the effect of covariates on time to first exacerbation. In total, 7376 patients were included in the analysis: 63.5% non-exacerbators, 22.9% infrequent, 13.6% frequent exacerbators. Factors significantly associated with exacerbation risk were age, sex, body mass index, COPD duration and severity, smoking history, baseline inhaled corticosteroid use, and preceding antibiotic or systemic corticosteroid courses. Frequent exacerbators had greater severity and duration of COPD, received more pulmonary medication, and ≥ 2 systemic corticosteroid or antibiotic courses in the preceding year, and were more likely to be female and ex-smokers. The small proportion of frequent exacerbators (13.6%) accounted for 56.6% of exacerbation-related hospitalisations, which, overall, were associated with a three-fold increase in mortality. The frequent exacerbator phenotype was closely associated with exacerbation-related hospitalisations, and exacerbation-related hospitalisations were associated with poorer survival.

Variant anatomy of renal arteries is important in renal transplant, vascular reconstruction, and uroradiological procedures. The variations show ethnic and population differences. Data from Africans are scarce and altogether absent for Kenyans. To describe patterns of origin, trajectories and branching of renal arteries in a Kenyan population. Descriptive cross-sectional study conducted in the Department of Human Anatomy, University of Nairobi. Three hundred and fifty six kidneys from 178 cadavers and postmortem specimens were used in the study. Aorta, renal arteries and kidneys were exposed by dissection. Number, trajectories, level of branching, number of branches and point of entry into the kidney were recorded. Data was analyzed using SPSS version 16.0, and presented using macrographs, tables, and bar charts. Additional arteries occurred in 14.3% of the cases. In 82.4% of these, there was one additional artery. Fifty nine point five per cent of the double renal arteries were parallel and 7.1% crossed. Of the 305 single arteries, 76.4% showed hilar, 21.6% prehilar and 2% intraparenchymal branching. In the hilar branching, ladder type was present in 65% and fork type in 35%. Bifurcation and trifurcation were present in 59.6% and 33.1% respectively. Polar arteries were present in 16.9% cases. Over 14% of the Kenyan population may have additional renal arteries while more than 20% show early branching. Several trajectories and hilar branching patterns exist which renal transplant surgeons and radiologists should be aware of to avoid inadvertent vascular injury.

Objective To compare the clinical consultations provided by American and Kenyan pharmacy students in an acute care setting in a developing country. Methods The documented pharmacy consultation recommendations made by American and Kenyan pharmacy students during patient care rounds on an advanced pharmacy practice experience at a referral hospital in Kenya were reviewed and classified according to type of intervention and therapeutic area. Results The Kenyan students documented more interventions than American students (16.7 vs. 12.0 interventions/day) and provided significantly more consultations regarding human immunodeficiency virus (HIV) and antibiotics. The top area of consultations provided by American students was cardiovascular diseases. Conclusions American and Kenyan pharmacy students successfully providing clinical pharmacy consultations in a resource-constrained, acute-care practice setting suggests an important role for pharmacy students in the reconciliation of prescriber orders with medication administration records and in providing drug information.

A survey of schoolchildren's exposure to secondhand smoke in Malaysia
2011-01-01
Background There is a lack of data describing the exposure of Malaysian schoolchildren to Secondhand Smoke (SHS). The aim of this study is to identify factors influencing schoolchildren's exposures to SHS in Malaysia. Method This cross-sectional study was carried out to measure salivary cotinine concentrations among 1064 schoolchildren (10-11 years) attending 24 schools in Malaysia following recent partial smoke-free restrictions. Parents completed questionnaires and schoolchildren provided saliva samples for cotinine assay. Results The geometric mean (GM) salivary cotinine concentrations for 947 non-smoking schoolchildren stratified by household residents' smoking behaviour were: for children living with non-smoking parents 0.32 ng/ml (95% CI 0.28-0.37) (n = 446); for children living with a smoker father 0.65 ng/ml (95% CI 0.57-0.72) (n = 432); for children living with two smoking parents 1.12 ng/ml (95% CI 0.29-4.40) (n = 3); for children who live with an extended family member who smokes 0.62 ng/ml (95% CI 0.42-0.89) (n = 33) and for children living with two smokers (father and extended family member) 0.71 ng/ml (95% CI 0.40-0.97) (n = 44). Parental-reported SHS exposures showed poor agreement with children's self-reported SHS exposures. Multiple linear regression demonstrated that cotinine levels were positively associated with living with one or more smokers, urban residence, occupation of father (Armed forces), parental-reported exposure to SHS and education of the father (Diploma/Technical certificate). Conclusions This is the first study to characterise exposures to SHS using salivary cotinine concentrations among schoolchildren in Malaysia and also the first study documenting SHS exposure using salivary cotinine as a biomarker in a South-East Asian population of schoolchildren. Compared to other populations of similarly aged schoolchildren, Malaysian children have higher salivary cotinine concentrations. The partial nature of smoke-free restrictions in

The problem of nutrition of schoolchildren as the main index of health status is considered. Recommendations for implementation of correction system of school feeding in conditions of Siberia will be presented. The purpose of work: on the basis of the results of monitoring living activity and assessment of the health of schoolchildren of different age groups in Siberia to develop guidelines on the rational balanced nutrition. Studies bear witness to inadequate diet and regimen of feeding of schoolchildren. In Siberia a progressive deterioration in the health of students during the years of learning is observed, part of diseases is associated with an unbalanced diet. We offer the project, in course of realization of which study in schools are carried out, scientifically grounded recommendations on appropriate diet and regimen of feeding for schoolchildren of different age groups in the Siberia in the cold and warm period of the year are developed. Implementation of recommendations will result in the general improvement of children health and reduction in medical aid appealability due to diseases of the gastrointestinal tract.

[Fitness indicators in Mexican schoolchildren with overweight and obesity].
López-Alonzo, Salvador Jesús; Rivera-Sosa, Juan Manuel; Buenaventura Pardo-Remetería, José; Muñoz-Daw, María de Jesús
The components of physical fitness are important as indicators of health in school children. The main objective of this study was to analyze the differences in the components of fitness among school children overweight /obese and normal. 491 schoolchildren participated, from the city of Chihuahua, Mexico. Components of physical condition, anthropometric variables and blood pressure were measured. Descriptive statistics, analysis of variance and frequency measurements were performed, including only the students who performed all the tests. 45% (n = 205) of the sample were girls and 55% (n = 251) were boys. The mean age in girls was 8.8 ± 1.8 years, and in boys 8.9 ± 1.9 years. 39% of schoolchildren were overweight or obese. Waist circumference shows 15.6% of school children with a percentile ≥90, and regarding blood pressure about 13.1% of the children are classified with some form of hypertension. Schoolchildren with normal weight show greater flexibility (0.007) *, more repetitions in the arm flexions (0,000)* and abdominal pushups (0,000)*, and less time in the speed test (0.008)* when compared to schoolchildren with obesity. In the present study, we observed that schoolchildren with overweight and obesity have a significantly lower performance in physical tests. So, the different aspects of physical condition evaluated can serve as immediate indicators of potential health risks for overweight children.

Mooses and colleagues suggest that running economy alone does not explain superior distance running performance in elite Kenyan runners. Whilst we agree with the multi-factorial hypothesis for Kenyan running success, we do not believe that running economy can be overlooked to the extent that it was based on this particular study. Based on the methods used and the range of athletes tested, in this response letter we question whether this study provides any basis for downplaying the influence of running economy or suggesting that other factors compensate for it to enable superior performance.

The purpose of this study was to investigate the relationship between running economy (RE) and performance in a homogenous group of competitive Kenyan distance runners. Maximal aerobic capacity (VO2max) (68.8 ± 3.8 ml∙kg(-1)∙min(-1)) was determined on a motorised treadmill in 32 Kenyan (25.3 ± 5.0 years; IAAF performance score: 993 ± 77 p) distance runners. Leg anthropometry was assessed and moment arm of the Achilles tendon determined. While Achilles moment arm was associated with better RE (r(2) = 0.30, P = 0.003) and upper leg length, total leg length and total leg length to body height ratio were correlated with running performance (r = 0.42, P = 0.025; r = 0.40, P = 0.030 and r = 0.38, P = 0.043, respectively), RE and maximal time on treadmill (t(max)) were not associated with running performance (r = -0.01, P = 0.965; r = 0.27; P = 0.189, respectively) in competitive Kenyan distance runners. The dissociation between RE and running performance in this homogenous group of runners would suggest that RE can be compensated by other factors to maintain high performance levels and is in line with the idea that RE is only one of many factors explaining elite running performance.

Although increased carotid intima-media thickness (cIMT), soluble adhesion molecules and proinflammatory biomarkers are strongly implicated in the development of atherosclerotic lesions, the role of obesity and metabolic syndrome (MetS) in atherogenicity and inflammation among schoolchildren is not well investigated. To determine the levels of cIMT, endothelial dysfunction and inflammatory biomarkers in a group of schoolchildren with obesity and MetS. Eighty-seven schoolchildren (age 10-15 years) were categorised into three groups: normal bodyweight group, obese group and severely obese with MetS group (17 boys and 12 girls in each group). Levels of cIMT were measured with high-resolution B-mode ultrasound. Serum proinflammatory cytokines interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β), and soluble adhesion molecules E-selectin, vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1(ICAM-1) were measured. Mean cIMT levels were significantly higher (p 0.05) among severely obese schoolchildren with MetS (0.49 ± 0.02 mm) compared with both the obese (0.43 ± 0.03 mm) and the normal bodyweight counterparts (0.36 ± 0.03 mm). Serum levels of IL-6, TNF-α, IL-1β, E-selectin, VCAM-1 and ICAM-1 were significantly higher (p 0.05) in severely obese with MetS and obese children compared with the normal bodyweight group. However, no significant differences (p >0.05) were found between the severely obese schoolchildren with MetS and the obese without MetS. Severely obese schoolchildren having MetS exhibited higher cIMT levels than obese and normal bodyweight counterparts. Biomarkers of inflammation and endothelial dysfunction were higher in obese schoolchildren, but biomarkers were not increased any further by the degree of obesity nor the MetS cluster.

To estimate the prevalence and describe the distribution of trachoma among schoolchildren in Brazilian municipalities. Cross-sectional study, using cluster sampling, of the schoolchildren population of the Brazilian municipalities with Human Development Index - Municipal lower than the national average. This trachoma prevalence survey was conducted by the Ministry of Health, in the period 2002-2007. There were 119,531 schoolchildren selected from 2,270 schools located in 1,156 municipalities. The selected schoolchildren underwent an external ocular examination, with a magnifying glass (2.5X), to detect clinical signs of trachoma according to the WHO criteria. The prevalence of trachoma, by state and national level, and their respective 95% confidence intervals were estimated. Chi-square and Chi-square for trends tests were used to compare categorical variables. There were 6,030 cases of trachoma detected, resulting in a prevalence of 5.0% (95%CI 4.5;5.4). There was no significant difference between the sexes. The prevalence of trachoma was 8.2% among children under 5 years of age, decreasing among higher age groups (p < 0.01). There was a significant difference in prevalence between urban and rural areas, 4.3% versus 6.2% respectively (p < 0.01). Cases were detected in 901 municipalities (77.7% of the sample), in all regions of the country. In 36.8% of the selected municipalities, the prevalence was higher than 5%. The study shows that trachoma is a significant public health problem in Brazil, contradicting the belief that the disease had been controlled in the country. The survey provides a baseline for evaluating planned interventions aimed at achieving the goal of global certification of elimination of trachoma as a cause of blindness in Brazil by 2020.

Kenyan Nurses Involvement in National Policy Development Processes
Juma, Pamela Atieno
2014-01-01
The aim of this study was to critically examine how nurses have been involved in national policy processes in the Kenyan health sector. The paper reports qualitative results from a larger mixed method study. National nonnursing decision-makers and nurse leaders, and provincial managers as well as frontline nurse managers from two Kenyan districts were purposefully selected for interviews. Interviews dealt with nurses' involvement in national policy processes, factors hindering nurses' engagement in policy processes, and ways to enhance nurses' involvement in policy processes. Critical theory and feminist perspectives guided the study process. Content analysis of data was conducted. Findings revealed that nurses' involvement in policy processes in Kenya was limited. Only a few nurse leaders were involved in national policy committees as a result of their positions in the sector. Critical analysis of the findings revealed that hierarchies and structural factors as well as nursing professional issues were the primary barriers constraining nurses' involvement in policy processes. Thus, there is need to address these factors both by nurses themselves and by nonnursing decision makers, in order to enhance nurses engagement in policy making and further the contribution to quality of services to the communities.

Skin diseases, especially skin infections, among schoolchildren in Africa can be a major health problem. The objective of this study was to determine the prevalences of skin diseases among children in rural and urban schools in three different African countries and to study the influence of socioeconomic level. Cross-sectional, population-based studies were performed in Ghana, Gabon, and Rwanda. Point prevalences of skin diseases were estimated on the basis of physical examination by at least one dermatologist. A total of 4839 schoolchildren were seen. The overall prevalence of schoolchildren with any skin disease was high and amounted to 34.6% and 42.0% in two Ghanaian studies, 45.8% in Gabon, and 26.7% in Rwanda. In children with skin diseases, skin infections represented the greatest proportion of disease, accounting for 14.7% and 17.6% of skin disease in the Ghanaian studies, and 27.7% and 22.7% in Gabon and Rwanda, respectively. Diseases with the highest prevalence were tinea capitis and bacterial skin infections, especially in rural areas and in schools serving children living at lower socioeconomic levels. The prevalences of skin diseases among African schoolchildren were high. Skin infections such as tinea capitis and pyoderma predominated. © 2013 The International Society of Dermatology.

BackgroundThere is little information about the possible role of Helicobacter pylori infection on appetite-regulating peptides in children. This study evaluated the association between H. pylori infection and serum levels of ghrelin, leptin, and obestatin in schoolchildren.MethodsOne hundred seventy-eight schoolchildren, students at boarding schools in Mexico City, participated. H. pylori infection status was determined every 6 months for 1 year by a breath test using 13 C-urea; schoolchildren with consistently positive or negative results were selected to participate. Age, sex, and body mass index (BMI) were recorded. Serum concentrations of total ghrelin, leptin, and obestatin via specific enzyme-linked immunosorbent assays were determined.ResultsSchoolchildren with H. pylori infection had lower concentration of leptin, -0.54 pg/ml (95% CI: -0.98 to -0.09), compared to the schoolchildren without infection, after adjustment by age, gender, and BMI. And the children with the infection had a median of obestatin lower in 0.99 ng/ml (95% CI: -1.93 to -0.06) compared with the uninfected children after adjustment by BMI.ConclusionAssociation was found between H. pylori infection and decreased serum concentrations of leptin and obestatin. These results suggest that in schoolchildren, H. pylori infection affects the levels of hormones implicated in regulating appetite and energy homeostasis.

Data on youth emotional and behavioral problems from societies in Sub-Saharan Africa are lacking. This may be due to the fact that few youth mental health assessments have been tested for construct validity of syndrome structure across multicultural societies that include developing countries, and almost none have been tested in Sub-Saharan Africa. The Youth Self-Report (YSR), for example, has shown great consistency of its syndrome structure across many cultures, yet data from only one developing country in Sub-Saharan Africa have been included. In this study, we test the factor structure of YSR syndromes among Kenyan youth ages 11–18 years from an informal settlement in Nairobi, Kenya and examine sex-differences in levels of emotional and behavioral problems. We find the eight syndrome structure of the YSR to fit these data well (Root Mean Square Error of Approximation=.049). While Kenyan girls have significantly higher internalizing (Anxious/Depressed, Withdrawn/Depressed, Somatic) problem scores than boys, these differences are of similar magnitude to published multicultural findings. The results support the generalizability of the YSR syndrome structure to Kenyan youth and are in line with multicultural findings supporting the YSR as an assessment of emotional and behavioral problems in diverse societies.

The term malnutrition includes malnutrition due to excess or obesity, underweight as well as stunted growth. Its prevalence in a population can be estimated using anthropometric variables. The aim of this study is to estimate the prevalence of malnutrition in Galician schoolchildren aged 6 to 15years in the school year 2013-2014. A cross-sectional study was conducted on a representative sample by gender and age of the Galician population of 6 to 15years old. The prevalence of obesity, underweight, and short stature was estimated by age and gender using the reference standards proposed by the World Health Organisation. Of the total of 7,438 schoolchildren weighed and measured, 16.4% had malnutrition. The prevalence of obesity was 14.8%, underweight was 0.7%, and short stature for age was estimated at 1%. Obesity was more prevalent among boys. As regards underweight and short stature, when there were differences, prevalence was higher among girls. In Galicia, 16 out of every 100 schoolchildren aged 6 to 15years had malnutrition, with that due to excess or obesity being the most frequent. Prevalence of underweight and short stature did not exceed 1%. This data shows that primary prevention measures should be promoted at an early age to reduce malnutrition due to excess or adiposity, in particular. Copyright © 2017.

Sleep duration is an important predictor of obesity and health. This study evaluated the association between late bedtime and screen time, and the role of geographical deprivation in English schoolchildren. We collected bedtime and waking time, screen time, sociodemographic data and measured body mass index in a cross-section of 1332 11-15-year-old schoolchildren (45.7% female) participating in the East of England healthy heart study. Logistic regression was used to determine the likelihood of late bedtime in schoolchildren with different screen time and from a different geographic location. Mean differences were assessed either on ANOVA or t-test. Approximately 42% of boys went to bed late at night compared with 37% of girls. When compared to those with <2 h of daily screen time, schoolchildren with 2-4 h of screen time were more likely [odds ratio (OR) = 1.50, 95% confidence interval (CI): 1.07-2.09] to go to bed late at night while those with >4 h of daily screen time were most likely to go to sleep late at night (OR, 1.97; 95%CI: 1.34-2.89). Late bedtime was associated with deprivation in schoolchildren. High screen time and deprivation may explain lateness in bedtime in English schoolchildren. This explanation may vary according to area deprivation and geographic location. Family-centered interventions and parental support are important to reduce screen time, late bedtime and increase sleep duration. © 2014 Japan Pediatric Society.

It is speculated that rural Kenyan children are more physically active than those in developed countries. The purpose of this study was to examine pedometer-measured physical activity levels of western Kenyan youth. Participants in this study were children in Levels 3 and 5 who attended a private primary school. The sample (n = 72) consisted of 43 girls and 29 boys (average age = 9.8 ± 1.1, range = 8-12 years). Age, gender, tribe, and height and weight measures were collected. Weight status category was determined according to CDC guidelines. Participants wore a sealed Yamax pedometer for 4 weekdays during the measurement period. Data analysis included descriptive statistics and 2-way ANOVA (age × gender). The total sample averaged 14558 ± 3993 daily steps. There was no significant effect for age [F(4,68) = 1.682, P = .102] nor significant age × gender interaction [F(4,68)=1.956, P = .117]. There was a significant effect for gender [F(1,68) = 4.791, P = .033], with boys (16262 ± 4698) significantly more active than girls (13463 ± 3051). The observed daily steps are higher than those observed in the U.S., similar to samples in other developed countries, but lower than Amish youth.

A survey of 19 166 secondary schoolchildren aged 12-17 years in five Australian states, the Australian Capital Territory and the Northern Territory was undertaken in 1987 to determine the prevalence of tobacco and alcohol use. Current smoking (that is, smoking at least one cigarette in the last week) rose with age to 27% in boys who were aged 16 years and to 30% in girls who were aged 16 years. The prevalence of current drinking (that is, consuming one alcoholic drink in the last week) rose with age to 55% in boys who were aged 16 years and to 50% in girls who were aged 17 years. Compared with an identical survey in 1984, the prevalence of smoking among 12- to 17-year-old schoolchildren had fallen significantly. The prevalence of drinking alcohol among 12- to 15-year-old schoolchildren also had fallen significantly, but not to the same extent as that of smoking; no significant reduction was found in the drinking of alcohol among 16- to 17-year-old schoolchildren. These trends are encouraging, but a need remains for all states to enact tobacco-control legislation, including the prohibition of tobacco advertising.

The management of obesity is complex and it must be multidisciplinary. Behavioral treatments for control of childhood obesity are based on family; these have a high degree of efficiency. It has been argued that when children and their parents are the main goal of the changes of behavior as a group, results of weight loss generally are better. The objective of this study was to establish the effect of an intervention based on family to reduce weight in students with overweight or obesity. Quasi-experimental study in schoolchildren from 6 to 12 years of age, from a family medicine unit in Ciudad Obregón, Sonora, México. The intervention group corresponded to 30 schoolchildren with overweight or obesity, and one or both of their parents with overweight or obesity; the control group included 30 schoolchildren with overweight or obesity, and normal-weight parents. Weight, height and body mass index (BMI) were measured at baseline, monthly, and at the end of the study. Student t test was used to contrast quantitative variables using the SPSS v.15 program. There were differences in weight, but not in BMI, probably due to the effect of size. Compared with the control group, a higher proportion of schoolchildren showed an improvement with regard to nutritional status. The family intervention is basic for the treatment of overweight and obesity in schoolchildren.
Undernutrition among Kenyan children: contribution of child, maternal and household factors.
Gewa, Constance A; Yandell, Nanette

To examine the contribution of selected child-, maternal- and household-related factors to child undernutrition across two different age groups of Kenyan under-5s. Demographic and Health Survey data, multistage stratified cluster sampling methodology. Rural and urban areas of Kenya. A total of 1851 children between the ages of 0 and 24 months and 1942 children between the ages of 25 and 59 months in Kenya. Thirty per cent of the younger children were stunted, 13 % were underweight and 8 % were wasted. Forty per cent of the older children were stunted, 17 % were underweight and 4 % were wasted. Longer breast-feeding duration, small birth size, childhood diarrhoea and/or cough, poor maternal nutritional status and urban residence were associated with higher odds of at least one form of undernutrition, while female gender, large birth size, up-to-date immunization, higher maternal age at first birth, BMI and education level at the time of the survey and higher household wealth were each associated with lower odds of at least one form of undernutrition among Kenyan children. The more proximal child factors had the strongest impact on the younger group of children while the intermediate and more distal maternal and household factors had the strongest impact on child undernutrition among the older group of children. The present analysis identifies determinants of undernutrition among two age groups of Kenyan pre-school children and demonstrates that the contribution of child, maternal and household factors on children's nutritional status varies with children's age.

Untreated refractive errors represent the main visual impairment in the world but also the easiest to avoid. The goal of this survey is to use clinical and epidemiological data to efficiently plan distribution of corrective glasses in a project supported by the Swiss Red Cross in the central region of Togo. To achieve this goal, 66 primary schools were identified randomly in the catchment area of the project. The teachers at these schools were previously trained to test visual acuity (VA). The schoolchildren referred by these teachers were examined by eye care professionals. The schoolchildren with ametropia (VA≤7/10 in at least one eye) underwent cycloplegic autorefraction. Of a total of 19,252 registered schoolchildren, 13,039 underwent VA testing by the teachers (participation rate=68%). Among them, 366 cases of ametropia were identified (prevalence about 3%). The average age of the schoolchildren examined was 10.7±2.3years, with a sex ratio of 1.06. Autorefraction, which was performed for 37% of the schoolchildren with ametropia allowed them to be classified into three groups: hyperopia (4%), myopia (5%) and astigmatism of all types (91%). Regardless of the type of ametropia, the degree of severity was mild in 88%. The results of this survey have highlighted the importance of the teachers' contribution to eye care education in the struggle against refractive errors within the school environment, as well as helping to efficiently plan actions against ametropia.

To determine and compare the extent of the nutrition transition between Kenyan and South African women. A nationally representative sample of women aged ≥15 years (n=1008) was assessed in Kenya. Weight, height, and waist and hip circumferences were measured. A 24-hour dietary recall was conducted with each participant. This data was compared with data of the Demographic and Health Survey (DHS) of women in South Africa (n=4481). Dietary intake of South African women was based on secondary data analysis of dietary studies using the 24-hour recall method (n=1726). In South Africa, 27.4% women had a BMI ≥30 kg/m(2) compared with 14.2% of Kenyan women. In both countries there were large urban-rural differences in BMI, with the highest prevalence in women in urban areas. BMI increased with age, as did abdominal obesity which was equally prolific in both countries with more than 45% of women in the older groups having a waist/hip ratio ≥0.85. The nutrient mean adequacy ratio (MAR) of the South African rural diet was lower than those of the Kenyans diet (55.9; 57.3%, respectively). Dietary diversity score (DDS) and food variety score (FVS) were significantly lower in South African rural women (3.3; 4.9) compared with Kenyans (4.5; 6.8). Urban-rural differences in diet and weight status indicates that the nutrition transition was similar in both countries despite large sociodemographic differences; however, rural Kenyan women had a better MAR, DDS, and FVS than South African women, most probably due to 60% having access to land.

OBJECTIVE To evaluate the association between being a recipient of the Bolsa Família program and oral health conditions in Brazilian schoolchildren. METHODS A cross-sectional study was conducted with 1,107 schoolchildren aged between eight and 12 years from 20 public and private schools in Pelotas, RS, Southern Brazil. A list of all children receiving the Bolsa Família program was provided by the participant schools. Demographic, socioeconomic and oral hygiene information were assessed using a questionnaire completed by the schoolchildren and their parents. Dental exams were performed to assess the presence of dental plaque and prevalence of dental caries. Data were analyzed by Chi-square test, Chi-square test for linear trend and multivariate Poisson Regression (prevalence ratio; 95% confidence interval). RESULTS Schoolchildren from non-nuclear families, with a DMFT ≥ 1 and who had never visited a dentist were associated with receiving the Bolsa Família. Final model showed that caries prevalence was twice as high (PR 2.00; 95%CI 1.47;2.69) in schoolchildren benefiting from the Bolsa Família . It was also showed that schoolchildren benefiting from the program presented greater severity of dental caries compared to school children from private schools (RR 1.53; 95%CI 1.18;2.00). After final adjustments, the prevalence of schoolchildren who have never visited a dentist was six times higher in children who received the government benefit (PR 6.18; 95%CI 3.07;12.45) compared to those from private schools. CONCLUSIONS Schoolchildren benefiting from the Bolsa Família program experienced more caries lesions and have less frequently accessed dental care services, which suggest the need to include oral health in the program.

Although intestinal protozoans are common etiologies of diarrhea, few studies have been conducted in Myanmar. This study planned to investigate the prevalence of Giardia lamblia, Entamoeba coli, Entamoeba histolytica, and Endolimax nana among schoolchildren and their guardians in suburban areas near Yangon, Myanmar. We performed a cross-sectional survey among schoolchildren and their guardians from 7 primary schools in South Dagon and Hlaing Thar Yar districts, Yangon, Myanmar. Stool samples were observed with a microscope after concentration technique and iodine staining. Total 821 stool samples, including 556 from schoolchildren and 265 from guardians, were examined. The median age was 6 years old for schoolchildren and 36 years old for guardians. A 53.1% of the school children and 14.6 % of the guardians were males. The overall prevalence of each intestinal protozoan species was as follows: 3.4% (28/821) for G. lamblia; 3.5% (29/821) for E. coli; 1.2% (10/821) for E. histoytica, and 3.0% for E. nana. This study showed that intestinal protozoans are common in primary schoolchildren and their guardians in suburban areas near Yangon, Myanmar. Health interventions, such as hand washing education, improvement of sanitation, and establishment of water purification systems are urgently needed in this area.

Foot ailments are common among schoolchildren, some of which may be attributed to wearing ill-fitting footwear. As schoolchildren often participate in athletic activity, they are doubly vulnerable to foot ailments, and are particularly vulnerable to conditions such as hallux valgus, Achilles tendonitis, athlete's foot, corns and calluses. Thus, there is an acute need for the design and manufacture of ergonomic footwear for this target group. While research on appropriate footwear for children has been carried out in relation to child populations in other societies, research on the circumstances of Sri Lankan schoolchildren is lacking. Neither the requisite design know-how nor the information for design is available to footwear manufacturers. This review of the literature is aimed at confirming the need for ergonomic footwear from the point of view of the effects of wearing ill-fitting shoes and at identifying the requirements in terms of design information, especially for schoolchildren of the age group five to ten years, to empower footwear manufacturers. PubMed, Google scholar and Science Direct were used for the literature search. 208 publications were read in full, 94 of which are referenced in this review. The review shows morphological measurements, behavior and activity patterns of schoolchildren and environmental conditions they are exposed to should be determined to formulate design information.

We analyze whether adverse childhood experiences predict weekly alcohol consumption patterns of Kenyan mothers and their partners. Randomly selected respondents (n = 1,976) were asked about adverse childhood experiences and alcohol consumption patterns for themselves and their partners. Fixed effect models were used to determine odds of reporting weekly alcohol consumption and the number of beverages typically consumed, controlling for wealth, age, education, and partner alcohol consumption. Cumulative adverse childhood experiences predicted higher odds of weekly alcohol consumption of the respondent and her partner. Childhood exposure to physical abuse, emotional neglect, and mental illness in the household significantly increased odds of weekly alcohol consumption by the respondent. More drinks consumed per typical session were higher among respondents with more cumulative adversities. Physical and emotional abuse significantly predicted number of drinks typically consumed by the respondent. To our knowledge, this is the first study to explore and find associations between adverse childhood experiences and alcohol consumption in Kenya. Consistent with high-income settings, exposure to childhood adversities predicted greater alcohol consumption among Kenyan women.

Despite the fact that about 10% of children experience mental health problems, they tend to hold negative views about mental illness. The objective of this study was to investigate the views of Nigerian schoolchildren towards individuals with mental illness or mental health problems. A cross-sectional design was used. Junior and senior secondary schoolchildren from rural and urban southwest Nigeria were asked: 'What sorts of words or phrases might you use to describe someone who experiences mental health problems?' The responses were tabulated, grouped and interpreted by qualitative thematic analysis. Of 164 students, 132 (80.5%) responded to the question. Six major themes emerged from the answers. The most popular descriptions were 'derogatory terms' (33%). This was followed by 'abnormal appearance and behaviour' (29.6%); 'don't know' answers (13.6%); 'physical illness and disability' (13.6%); 'negative emotional states' (6.8%); and 'language and communication difficulties' (3.4%). The results suggest that, similar to findings elsewhere, stigmatization of mental illness is highly prevalent among Nigerian children. This may be underpinned by lack of knowledge regarding mental health problems and/or fuelled by the media. Educational interventions and encouraging contact with mentally ill persons could play a role in reducing stigma among schoolchildren.

The prevalence of skin disease in low and middle income countries is high and communicable skin diseases are a significant public health problem. Tungiasis is an ectoparasite infestation caused by the flea Tunga penetrans, which has a widespread geographical distribution. Tungiasis causes painful skin lesions and may affect activities of daily living. We wished to determine the prevalence and impact of tungiasis and scabies in schoolchildren in southern Ethiopia. A cross-sectional study was performed in which students were examined by dermatologists and the skin disorders recorded. Individuals with pyogenic skin infections, scabies and tungiasis were also invited to complete the Children's Dermatology Life Quality Index. There was a high burden of skin disease amongst this cohort with more than 40% having an ectodermal parasitic skin disease. The majority of these were due to tungiasis. Tungiasis was evident in more than a third of children and was associated with onychodystophy. There was a significant association between wearing "closed" footwear and a greater number of tungiasis lesions but not tungiasis per se. Dermatophyte infections, acne and plantar maceration secondary to occlusive footwear were also common. Scabies and tungiasis appeared to have a significant negative effect on quality of life. Tungiasis is highly prevalent in schoolchildren in the part of Ethiopia where the study was conducted and is associated with a deleterious effect on quality of life. The role of footwear in both preventing and possibly exacerbating cutaneous ailments in this setting requires further study.

The aim of this study was to evaluate the effectiveness of the indirect instruction and the influence of the periodic reinforcement on the plaque index in schoolchildren. Forty schoolchildren aged from 7 to 9 years old were selected from a public school. After determining the initial O'Leary Plaque Index all schoolchildren were submitted to a program for oral hygiene through indirect instruction -"The Smiling Robot". The schoolchildren were divided into 2 groups: with and without motivation reinforcement. The index plaque exam was performed in both groups after 30, 60 and 90 days of the educational program. Comparing the groups, the plaque index decreasing could be observed in the group with reinforcement with statistically significant difference. For the group with reinforcement, statistically significant difference among the evaluations was found. For the group without reinforcement, significant decrease in the plaque index was found after 30 days when compared to the first, third and fourth evaluations. The indirect instruction with "The Smiling Robot "promoted a positive initial impact on the decrease of plaque index in the schoolchildren. The periodic reinforcements showed more suitable results and significant reduction of the plaque index in the course of the evaluations.

The International Study of Asthma and Allergies in Childhood (ISAAC) has reported the prevalence of asthma and allergic diseases in many countries. We used the ISAAC core written questionnaire to examine the prevalence of asthma and allergic diseases in 6- to 14-year old schoolchildren in Tokyo. In 2005, we conducted a cross-sectional survey of all schoolchildren in all public schools located in the Setagaya area of Tokyo. Data were collected from 27,196 children in 95 schools. Prevalence ranged from 10.5% to 18.2% for asthma symptoms and from 10.9% to 19.6% for atopic dermatitis, with both conditions tending to decrease with age. As has been previously reported for all age groups, significantly higher rates of current asthma are observed in boys than in girls. The prevalence of allergic rhinoconjunctivitis exhibited a different pattern from that of asthma and atopic dermatitis, peaking at the age of 10 (34.8%). Prevalence of allergic rhinoconjunctivitis was 1.5 to 2-fold higher than the previous ISAAC studies that were performed in Tochigi and Fukuoka. In all age groups, symptoms of allergic conjunctivitis were more frequent from February to May, which coincides with the Japanese cedar pollen season, and were less frequent between June to September. The prevalence of asthma and atopic dermatitis was higher in younger schoolchildren. Tokyo schoolchildren appear to have extremely high prevalence rates of seasonal allergic rhinoconjunctivitis.

The aim of the present study was to assess the association between untreated dental caries (UDC) and household food insecurity (HFI) among schoolchildren in different income strata. A population-based study was carried out with a sample of 584 12-y-old schoolchildren. Oral examinations were performed and HFI was determined using a validated scale. Other independent variables were analyzed for being of interest to the stratification of the results (per capita household income) or for acting as potential confounding variables. The prevalence of UDC and HFI was 45% and 39%, respectively. The multivariate models demonstrated that the UDC was significantly more prevalent among children in food-insecure households with per capita income of up to US$ 70.71 than among those in the same income stratum that were free of HFI [PR = 1.52 (95%CI = 1.01-2.29)]. HFI was associated with a greater frequency of UDC among low-income schoolchildren, but had no significant impact on this variable among children from other income strata. Thus, ensuring access to quality food may be a good strategy for minimizing inequities in oral health and reducing dental caries experience among schoolchildren from low-income families.

This study investigates the prevalence of asthma and asthma-related symptoms in New Orleans inner-city schoolchildren. A cross-sectional survey of 1535 elementary, middle, and high school children (aged 5-18) was conducted by using the International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire. Lifetime prevalence of wheezing was 39.4%, and lifetime prevalence of asthma was 24.4%. Wheezing during the previous 12 months was reported by 25.7% of the sample. Twenty-one percent of respondents reported having one or more attacks of wheezing per year, with 5.6% reporting four or more attacks per year. Many participants reported sleep disturbance (15.4%), with 6.2% reporting sleep disturbance more than once a week. The 12-month rate of speech limitation due to asthma exacerbation was 6.6%. Exercise-induced asthma was reported by 16.9% of the students, and nocturnal cough (not associated with cold) was reported by 27.3%. Overall, boys reported higher rates of symptoms than girls, and younger children (aged 6-7) reported greater symptoms than older children (aged 13-14). These findings show that prevalence of asthma in this population is elevated, and the ISAAC written questionnaire successfully identified inner-city children at risk for asthma in New Orleans.

Manganese (Mn) is an essential metal involved in multiple physiological functions. Environmental exposure to airborne Mn is associated with neurocognitive deficits in humans. Children, whose nervous system is in development, are particularly susceptible to Mn neurotoxicity. The objective of this study was to assess the association between Mn environmental exposure, and effects on visuoperception and visual memory in schoolchildren. We assessed schoolchildren between 7 and 11 years old, with similar socioeconomic status, from the mining district of Molango (n=148) and Agua Blanca (n=119, non-mining area) in Hidalgo state, Mexico. The Rey-Osterrieth Complex Figure (ROCF) test was used to assess visuoperception and short-term visual memory. Hair manganese (MnH) concentrations were determined. Linear regression models were constructed to estimate the associations between MnH and ROCF scores, adjusted for potential confounders. The geometric mean MnH was nine times higher in schoolchildren from the Mn mining area (5.25μg/g) than in schoolchildren from the non-mining area (0.55μg/g). For the ROCF Copy trial, MnH was significantly associated with an increase in distortion errors (tangency, closure), angle errors, overtracing (partial overtracing). In the Immediate Recall trial, MnH was significantly associated with increased overtracing (partial overtracing) and omissions, and negatively associated with the number of perceptual drawn units, total score and percentage immediate recall. MnH is associated with alterations in visuoperception and short-term visual memory in schoolchildren exposed to airborne Mn. Copyright © 2016 Elsevier B.V. All rights reserved.
Predicting asthma exacerbations in children.
Forno, Erick; Celedón, Juan C
2012-01-01
This review critically assesses recently published literature on predicting asthma exacerbations in children, while also providing general recommendations for future research in this field. Current evidence suggests that every effort should be made to provide optimal treatment to achieve adequate asthma control, as this will significantly reduce the risk of severe disease exacerbations. Children who have had at least one asthma exacerbation in the previous year are at highest risk for subsequent exacerbations, regardless of disease severity and/or control. Although several tools and biomarkers to predict asthma exacerbations have been recently developed, these approaches need further validation and/or have only had partial success in identifying children at risk. Although considerable progress has been made, much remains to be done. Future studies should clearly differentiate severe asthma exacerbations due to inadequate asthma control from those occurring in children whose asthma is well controlled, utilize standardized definitions of asthma exacerbations, and use a systematic approach to identify the best predictors after accounting for the multiple dimensions of the problem. Our ability to correctly predict the development of severe asthma exacerbations in an individual child should improve in parallel with increased knowledge and/or understanding of the complex interactions among genetic, environmental (e.g. viral infections) and lifestyle (e.g. adherence to treatment) factors underlying these events.

Identifying Overweight and Obesity in Brazilian Schoolchildren, 2014.
Pozza, Fernanda Seyr; Nucci, Luciana Bertoldi; Enes, Carla Cristina
For any intervention in a population, we need to understand population characteristics and needs. The School Health Program (PSE) is a Brazilian national proposal for the improvement of schoolchildren's quality of life by integrating health and education areas to address vulnerabilities that affect the development of students from public schools. To describe the prevalence of overweight and obesity in school-aged children and adolescents and to expound methods to evaluate the nutritional status deviation. Cross-sectional study. Schools in Itatiba, Sao Paulo, Brazil, participating in PSE. A total of 6829 schoolchildren aged 6 month to 15 years. Nutritional status and standard percentile curves for body mass index (BMI) for gender. In children younger than 5 years, the prevalence of being overweight was 13.9%; for those between 5 years or older and younger than 10 years, it was 33.9%; and for those 10 years or older, it was 34.0%. In males, obesity and severe obesity were more present (10.7% and 3.7%, respectively) than in girls (9.5% and 1.9%, respectively). Regarding location, it was found that the region with the highest income showed a higher prevalence of overweight children. Compared with the World Health Organization reference BMI curves, our reference percentile curve showed a higher standard for the cutoff points between normal range and overweight. From our results, we found that age and measures of weight and height in schoolchildren could contribute, in a cheap and simple way, to the assessment of nutritional status in a region. This is helpful in providing health monitoring and assisting in making public health decisions, as well as serving in comparison with other scientific studies. Partnership between education and health systems can facilitate and improve the quality of health management among schoolchildren.

To assess the nutritional status, physical activity, and eating habits of schoolchildren in Cercado de Lima (Lima district). Cross-sectional descriptive study. The sample included schoolchildren from first to fourth grade in four public elementary schools located in Cercado de Lima. The study variables were nutritional status, hemoglobin dose, physical activity, and eating habits. The percentages of the qualitative variables and central tendency measures for quantitative ones were calculated. The t-test and chi-squared test were applied to analyze differences between both genders. Of 824 schoolchildren included in the study, 24% were obese, 22% were overweight, 5% had short stature, and 11.9% had anemia; in all instances, there were no substantial gender differences. More than 40% of schoolchildren would eat crackers and drink packaged juice and/or soda two or more times a week. In addition, 28% of schoolchildren were inactive; there were significant differences in both genders (P<0.05). Obesity is an ongoing problem with higher rates than overweight and, together, the aforementioned problems affect almost 50% of schoolchildren surveyed. Similarly, the study revealed patterns associated with a sedentary lifestyle and frequent consumption of foods with high levels of sugar, salt, and/or fats.

Background: We aimed to study the prevalence of overweight and obesity and to assess its familial clustering among schoolchildren in northern China. Methods: A cross-sectional study was conducted on 95,292 schoolchildren in northern China to investigate the prevalence of overweight and obesity. A group of overweight and obese children (n = 450) was selected using a cluster sampling method. Answers from a questionnaire on their and their families’ nutrition and behaviors were recorded and analyzed statistically. Results: The prevalence of overweight and obesity in schoolchildren was 27.4% and 13.2%, respectively. The prevalence of overweight and obesity were significantly higher in boys than in girls. The prevalence of familial clustering of overweight and obesity was 75.3% and 20.3%, respectively. The prevalence of overweight in first-generation (parents) and second-generation (grandparents) relatives was 54.6% and 53.1%, respectively. There was a linear trend toward correlation between age and the rates of overweight and obesity. The familial clustering of obesity with family income reached statistical significance. Conclusion: The prevalence of overweight and obesity was extremely high, especially among boys and their fathers. Evidence of familial clustering of overweight and obesity among schoolchildren and their parental family members in northern China is emerging. PMID:25664106

Conclusion Tungiasis is highly prevalent in schoolchildren in the part of Ethiopia where the study was conducted and is associated with a deleterious effect on quality of life. The role of footwear in both preventing and possibly exacerbating cutaneous ailments in this setting requires further study. PMID:28771469

To describe a dermatitis outbreak caused by exposure to pine processionary caterpillar (Thaumetopoea pityocampa ) that took place on March 15th, 2006, in schoolchildren during their stay at a rural farm holiday centre in Villahermosa del Río (Castellón). A cross sectional epidemiological study was carried out on seventy schoolchildren, average age 10 years, and 3 teachers from Castellón. A specific questionnaire was used to be filled in by the schoolchildren. Six cases of dermatitis (attack rate 8.6%: 6/70) took place after children had swum in the heated farm pool and dried themselves with towels that had been left outside the heated pool enclosure, where they had come into contact with Thaumetopoea pityocampa. The cases needed medical attention, with prescription of antihistamine drugs, corticosteroids, and cold showers. The risk of dermatitis from contact with Thaumetopoea pityocampa was very high (Odds Ratio=157.2 Confidence Interval 95% 18.4-inf). Thaumetopoea pityocampa were collected near the swimming pool and Thaumetopoea pityocampa nests were observed on nearby pines. The presence of Thaumetopoea pityocampa near rural centres can cause outbreaks. Health education for schoolchildren and the removal of Thaumetopoea pityocampa nests near these centres are required.

This study evaluated the impact of molar-incisor hypomineralization (MIH) on oral health-related quality of life (OHRQoL) according to the perceptions of schoolchildren and their parents/caregivers. This cross-sectional study consisted of a sample of 594 schoolchildren between 11 and 14 years of age and their parents/caregivers who answered the questionnaires CPQ11-14ISF:16 and P-CPQ, respectively. The main independent variable of this study was MIH of the schoolchildren. Experience of dental caries, malocclusion, and socioeconomic status were treated as confounding variables. Statistical analysis used descriptive analysis and Poisson regression with robust variance. The prevalence of MIH was 18.9%. The overall P-CPQ score ranged from 0 to 35 (average = 7.26 ± 6.84), and the overall CPQ11-14ISF:16 score ranged from 0 to 47 (average = 11.92 ± 7.98). Severe MIH was associated with a greater negative impact of the "functional limitation" domain (RR = 1.41; 95%CI = 1.01-1.97), according to parents'/caregivers' perceptions. Severe MIH was associated with a greater negative impact of the "oral symptom" domain (RR = 1.30; 95%CI = 1.06-1.60) and functional limitation domain (RR = 1.42; 95%CI = 1.08-1.86), according to the schoolchildren's perceptions. Schoolchildren with severe MIH had a greater negative impact on the oral symptom and functional limitation domains than those without MIH. According to parents'/caregivers' perceptions, schoolchildren with severe MIH had a greater negative impact on the functional limitation domain than those without MIH.

Mooses, M, Haile, DW, Ojiambo, R, Sang, M, Mooses, K, Lane, AR, and Hackney, AC. Shorter ground contact time and better running economy: evidence from female Kenyan runners. J Strength Cond Res XX(X): 000-000, 2018-Previously, it has been concluded that the improvement in running economy (RE) might be considered as a key to the continued improvement in performance when no further increase in V[Combining Dot Above]O2max is observed. To date, RE has been extensively studied among male East African distance runners. By contrast, there is a paucity of data on the RE of female East African runners. A total of 10 female Kenyan runners performed 3 × 1,600-m steady-state run trials on a flat outdoor clay track (400-m lap) at the intensities that corresponded to their everyday training intensities for easy, moderate, and fast running. Running economy together with gait characteristics was determined. Participants showed moderate to very good RE at the first (202 ± 26 ml·kg·km) and second (188 ± 12 ml·kg·km) run trials, respectively. Correlation analysis revealed significant relationship between ground contact time (GCT) and RE at the second run (r = 0.782; p = 0.022), which represented the intensity of anaerobic threshold. This study is the first to report the RE and gait characteristics of East African female athletes measured under everyday training settings. We provided the evidence that GCT is associated with the superior RE of the female Kenyan runners.

To estimate the prevalence of overweight / obesity in schoolchildren, and to investigate its association with parents' nutritional status, socioeconomic factors and food consumption. Cross-sectional study with 1,223 schoolchildren, 7 to 10 years old from Florianópolis, SC. We collected anthropometric measures directly and dietary intake of previous day; parents' data were collected from a socioeconomic and self-reported anthropometric questionnaire. Schoolchildren's nutritional status was defined using the Body Mass Index (BMI) for age and sex according to the reference data of the World Health Organization (2007), and parents' nutritional status was defined according to the World Health Organization BMI cutoff points (1995). We performed bivariate and multivariate analysis using Poisson regression. Prevalence of overweight/obesity was 36.2% in boys and 32.7% among girls. The prevalence was 56.3% and 27.5% in fathers and mothers, respectively. In the final model, mother's (p = 0.001) and father's nutritional status (p = 0.050) remained directly associated with schoolchildren's overweight/obesity. The prevalence of overweight/obesity was 1.58 times higher in schoolchildren with overweight/obese mothers, and 1.41 times higher in schoolchildren with overweight/obese fathers, compared to mothers and fathers without the condition. There was a high prevalence of overweight/obesity among schoolchildren, which was associated with the nutritional status of mothers and fathers. These results confirm the need to prevent overweight/obesity in schoolchildren with actions that also involve the family environment in order to reduce obesity in this population.

Objectives The aim of the present study was to estimate the incidence and spontaneous clearance rate of Helicobacter pylori infection and the effect of some variables on these outcomes in schoolchildren. Methods From May 2005 to December 2010, 718 schoolchildren enrolled in 3 public boarding schools in Mexico City participated in the follow-up. At the beginning of the study and every 6 months thereafter, breath samples were taken to detect H pylori infection; blood samples and anthropometric measurements were taken to evaluate nutritional status. Data on sociodemographic characteristics were collected. Results The prevalence of H pylori infection was 38%. The incidence rate was 6.36%/year. Schoolchildren with anemia or iron deficiency at the beginning of the study (who received iron supplements) showed a higher infection acquisition rate than those with normal iron nutritional status, hazard ratio (HR) 12.52 (95% confidence interval [CI] 4.01%–39.12%), P <0.001 and HR 2.05 (95% CI 1.09%–3.87%), P = 0.027, respectively. The spontaneous clearance rate of the infection was 4.74%/year. The spontaneous clearance rate was higher in children who had iron deficiency (who received iron supplements), HR 5.02 (95% CI 1.33%–18.99%), P = 0.017, compared with those with normal nutritional iron status. It was lower in schoolchildren with ≥2 siblings compared with schoolchildren with 1 or no siblings, HR 0.23 (95% CI 0.08%–0.63%), P = 0.004. Conclusions H pylori infection status is dynamic in schoolchildren. Variables related to health status and infection transmission, such as iron status and number of siblings, are important for the incidence and spontaneous clearance of H pylori infection.

Background Handwashing with soap (HWWS) is a simple and effective measure to prevent transmission of fecal–oral disease and other infectious diseases in school-age children. To promote the behavior, we need to understand their HWWS compliance. The aim of this article is to describe handwashing behavior and HWWS compliance and to identify associated factors among schoolchildren in the multiethnic rural area of northern Vietnam. Methods The study was conducted in six primary and secondary schools and in the homes of four ethnic villages in northern Vietnam. Quantitative methods included face-to-face interviews with, and demonstration of handwashing protocol to, 319 schoolchildren in first, fourth, and seventh grades. Qualitative methods included structured observations at six schools and 20 homes comprising 24 children. The dependent variable was the self-reported HWWS behavior (yes/no). The independent variables included grade, school type, gender, ethnicity group, owning home latrine, and household assets. Logistic regression modelling was performed to examine associations between HWWS behavior and demographic factors. Results Among the 319 schoolchildren interviewed, 66% reported HWWS. Through the demonstration protocol, only 10 out of 319 schoolchildren, performed HWWS satisfactorily. The percentage of students who washed their hands at recommended times (30–60 sec) was 58%. This proportion increased by grade (from 34% among grade 1 to 67% among grade 7; p<0.05). Correlates of self-reported HWWS were more common in higher grades [grade 4 vs. grade 1: odds ratio (OR)=4.14 (2.00–8.56), grade 7 vs. grade 1: OR=7.76 (3.67–16.4)] and less common in ethnic minority groups [Xa Phó vs. Kinh-Tay: OR=0.28 (0.11–0.70)]. All 20 homes of schoolchildren visited had soap and water but none of the six schools had soap for handwashing. Conclusions This article describes poor compliance of schoolchildren with HWWS in a multiethnic population in Vietnam. Education on

This study was designed to evaluate the role of vitamin D, muscle fatigue biomarkers, and mechanical factors in the progression of low back pain (LBP) in schoolchildren. Children and adolescents frequently suffer from LBP with no clear clinical causes, and >71% of schoolchildren aged 12-17 years will show at least one episode of LBP. A total of 250 schoolchildren aged 12-16 years were randomly enrolled in this study. For all schoolchildren height, weight, percentage of daily sun exposure and and areas of skin exposed to sun, method of carrying the bag, and bag weight and type were recorded over a typical school week. Pain scores, physical activity (PA), LBP, serum vitamin 25(OH)D level, serum bone-specific alkaline phosphatase, creatine kinase (CK), and lactate dehydrogenase (LDH) activities and calcium (Ca) concentrations were estimated using prevalidated Pain Rating Scale, modified Oswestry Low Back Pain Disability Questionnaire, short-form PA questionnaire, and colorimetric and immunoassay techniques. During the period of October 2013-May 2014, LBP was estimated in 52.2% of the schoolchildren. It was classified into moderate (34%) and severe (18%). Girls showed a higher LBP (36%) compared with boys (24%). In schoolchildren with moderate and severe LBP significantly higher ( P =0.01) body mass index, waist, hip, and waist-to-hip ratio measurements were observed compared with normal schoolchildren. LBP significantly correlated with less sun exposure, lower PA, sedentary activity (TV/computer use), and overloaded school bags. In addition, schoolchildren with severe LBP showed lower levels of vitamin 25(OH)D and Ca and higher levels of CK, LDH, and serum bone-specific alkaline phosphatase compared with moderate and healthy schoolchildren. Stepwise regression analysis revealed that age, gender, demographic parameters, PA, vitamin D levels, Ca, CK, and LDH associated with ~56.8%-86.7% of the incidence of LBP among schoolchildren. In children and adolescents, LBP was

To determine the ioduria and iodine concentration in table salt in Peruvian elementary schoolchildren. A cross-sectional study was performed. A total of 8,023 elementary schoolchildren, who voluntarily participated, were included. Multistage stratified probability sampling was performed, and the sample was obtained by systematic selection. Ioduria was determined via spectrophotometry (Sandell-Kolthoff method), and the amount of iodine in salt was evaluated volumetrically. The data were processed by means of analysis for complex samples with a weighting factor. Medians, percentiles, and confidence intervals were calculated, and the Mann-Whitney U and Kruskal-Wallis H tests were used, where appropriate. Nationwide, the median ioduria in schoolchildren was 258.53 ug/L, being higher in boys (265.90 ug/L) than in girls (250.77 ug/L). The median ioduria in urban areas was higher (289.89 ug/L) than that in rural areas (199.67 ug/L), while it was 315.48 ug/L in private schools and 241.56 ug/L in public schools (p<0.001). The median iodine concentration in table salt was 28.69 mg/kg. Of the total salt samples, 23.1% contained less than 15 mg/kg of iodine. The median ioduria in elementary schoolchildren exceeded normal levels, according to the criteria of the World Health Organization, with differences between urban and rural areas and public and private schools.
Fluid intake survey among schoolchildren in Belgium
2014-01-01
Background In childhood, inadequate fluid intakes can lead on the short term, to reduced physical and cognitive performances. However, few data are available on the fluid intake among schoolchildren in Belgium. The main aim of this study is to evaluate total fluid intake provided by different types of beverages in a sample of Belgian schoolchildren, in order to assess the percentage of individuals complying with the European Food Safety Authority recommendations for total fluid intake. A secondary aim was to characterize the study population in terms of determinants of the total fluid intake requirements. Methods A child friendly “fluids and liquid food” diary was used to prospectively record the volume and frequency of beverage consumption over 7 days from 1045 schoolchildren. This diary also recorded the practice of physical activity. An adequate fluid intake was defined as an intake ≥ 75% of the age-specific adequate intake recommended by the EFSA. Results The median (P25-P75) of habitual daily fluid intake was 864 (608–1104) ml/day, with 355 (194–579) coming from drinking water. This habitual daily fluid intake varied significantly among the three investigated EFSA groups (girls and boys aged from 8 years, girls from 9 to 13 and boys from 9 to 13), except for the drinking water (P = 0.906). The highest medians of fruit juice, sugar-sweetened beverages and milk and derivatives were found among boys of 9–13. Only 9.5% of the children had an adequate fluid intake, with a value of 19.2% among the 8 years old girls and boys, 7.0% among girls of 9–13 and 8.4% among boys of 9–13. In the whole sample, 27.7% of the children declared to drink less than 3-4x/day, 56% drunk water less than 2x/day and 7.7% drunk no water at all. Every day, 27.1% and 34.1% of the children drank respectively one fruit juice and one sugar-sweetened beverage. Conclusion Belgian schoolchildren have an inadequate total fluid intake.

To report on the prevalence of overweight and obesity among pre-school children in Kenya and examine the associations between childhood overweight and selected maternal and child-related factors. Demographic Health Survey data, multistage stratified cluster sampling methodology. Rural and urban areas of Kenya. A total of 1495 children between the ages of 3 and 5 years in Kenya. Over 30 % of the children were stunted, approximately 16 % were underweight, 4 % were wasted, approximately 18 % were overweight and 4 % were obese; 8 % were both overweight/obese and stunted. Maternal overweight and obesity, higher levels of maternal education, being a large or very large child at birth, and being stunted were each associated with higher odds of overweight and obesity among Kenyan children. Older children and large household size were each associated with lower odds of overweight and obesity among Kenyan children. The analysis demonstrates the presence of under- and overnutrition among Kenyan pre-school children and the importance of focusing on expanding efforts to prevent and treat malnutrition within this population. It also identifies some of the modifiable factors that can be targeted in these efforts.

To assess thyroid status among the schoolchildren around Semipalatinsk Nuclear Testing Site (SNTS), Kazakhstan, and to evaluate the current status of iodine deficiency in this area, we performed medical screening of schoolchildren in two villages, Kaynar and Karaul villages, East Kazakhstan Region, Republic of Kazakhstan, located within 100 km of SNTS. A total of 196 schoolchildren were chosen at random. Control groups comprised 250 schoolchildren from Nagasaki, an iodine-rich area, and 100 schoolchildren from Gomel, an iodine-deficient area contaminated by the Chernobyl Nuclear Power Plant accident. Ultrasound screening of thyroid revealed three cases of benign thyroid disease (two cases of goiter and one single cyst), but no cases suspicious of malignancy. The urinary iodine (UI) concentrations of subjects in Kaynar and Karaul ranged from 21.8 to 735.8 microg/L, 4.3% of whom showed low UI concentrations (<50 microg/L), compared with 0% in the Nagasaki group and 52% in the Gomel group. The median UI concentration in Kaynar and Karaul was 153.2 microg/L, which was significantly lower than that in Nagasaki (366.3 microg/L, p<0.0001) but higher than that in Gomel (47.3 microg/L, p<0.0001). In conclusion, there was a low incidence of morphological abnormalities in the thyroid, and no evidence for severe iodine deficiency among the Kazakhstani children studied. These results suggest that there is no transgenerational risk for schoolchildren born from parents irradiated as a result of tests carried out in SNTS.

Iodine deficiency is a public health problem, and iodine nutritional status should therefore be regularly measured. To ascertain iodine nutritional status in Asturias and its relation to use of iodized salt and to other sociodemographic and nutritional parameters. A descriptive, observational study was conducted in a random sample of schoolchildren aged 5 to 14 years, in whom urinary iodine levels were measured by high-performance liquid chromatography. Families completed a survey on use of iodized salt, consumption of dairy products and fish, and sociodemographic data. The study sample consisted of 705 schoolchildren (51.1% females) with a mean age of 9.9 years (SD 2.6). In a total of 620 valid measurements, mean urinary iodine level was 204.1 μg/L (SD 120.6), while the median value was 180.7 μg/L (P 25 -P 75 : 124-252.3 μg/L, interquartile range 128.3 μg/L). Urinary iodine levels were <100 μg/L in 16.6% of children, and very low (<20 μg/L) in 0.2%. Iodized salt was used in 69.3% of all households, and in all school canteens. Consumption of dairy products was significantly associated to urinary iodine levels (P<.0005). Iodine nutrition of Asturian schoolchildren is adequate, although the target of use of iodized salt in 90% of households is still far away. Adequate iodine nutrition may be due to other sources, such as dairy products. Public health campaigns are required to promote iodized salt consumption. Regular assessment of iodine nutritional status is also needed. Copyright © 2017 SEEN y SED. Publicado por Elsevier España, S.L.U. All rights reserved.

To determine the association between overweight/obesity in schoolchildren with FTO rs9939609 polymorphism (fatmass and obesity associated) and family history of obesity. Cross-sectional study comprising a sample of 406 children aged 7-17 years in a city in southern Brazil. Overweight/obesity in schoolchildren was assessed by body mass index (BMI), and family history of obesity was self-reported by parents. Polymorphism genotyping was performed by real time PCR (polymerase chain reaction). The association between the nutritional status of schoolchildren with the presence of family obesity, stratified by polymorphism genotypes (AA [at-risk for obesity], AT, and TT), was assessed by prevalence ratio values (PR) through Poisson regression. Among schoolchildren with the AA genotype, 57.4% had overweight/obesity; the percentage was lower for the AT and TT genotypes (33.1% and 28.9%, respectively). Overweight/obesity in schoolchildren was associated with a family history of obesity, especially among children with the AA genotype. The prevalence was higher among those with an obese mother (PR: 1.28; p<0.001), obese maternal or paternal grandmother (PR: 1.22; p=0.047), and obese paternal grandfather (PR: 1.32; p<0.001). There is an association between the AA genotype of rs9939609 polymorphism and BMI among schoolchildren. The association between overweight/obesity in schoolchildren with a family history of obesity was found mainly among students with the AA genotype. Copyright © 2016 Sociedade Brasileira de Pediatria.

Hand hygiene is known to be effective in preventing hospital and community-acquired infections. The increasing number of hand sanitizer brands in Kenyan hospitals and consumer outlets is of concern. Thus the main aim of this study was to evaluate the anti-bacterial efficacy and organoleptic properties of these hand sanitizers in Kenya. This was an experimental, laboratory-based study of 14 different brands of hand sanitizers (coded HS1-14) available in various retail outlets and hospitals in Kenya. Efficacy was evaluated using standard non-pathogenic Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923) and Pseudomonas aeruginosa (ATCC 27853) as per the European Standard (EN). The logarithmic reduction factors (RF) were assessed at baseline and after treatment, and log reduction then calculated. Ten and 25 healthy volunteers participated in the efficacy and organoleptic studies respectively. Four (28.6%) hand sanitizers (HS12, HS9, HS13 and HS14) showed a 5.9 reduction factor on all the three bacteria strains. Seven (50%) hand sanitizers had efficacies of <3 against all the three bacteria strains used. Efficacy on E. Coli was higher compared to the other pathogens. Three hand sanitizers were efficacious on one of the pathogens and not the other. In terms of organoleptic properties, gel-based formulations were rated far higher than the liquid based formulations brands. Fifty percent (50%) of the selected hand sanitizers in the Kenyan market have efficacy that falls below the World Health Organization (WHO) and DIN EN 1500:2013. Of the 14 hand sanitizers found in the Kenyan market, only four showed efficacies that were comparable to the WHO-formulation. There is a need to evaluate how many of these products with <3 efficacy that have been incorporated into the health system for hand hygiene and the country's policy on regulations on their usage.

To describe pesticide concentrations in distinct environmental matrices at two time points (low and high seasons in local agricultural production) and to estimate the association between the presence of pesticide residues in matrices and the use of pesticides in the home with the sociodemographic variables of schoolchildren in the Province of Talca, Chile. A cross-sectional study was conducted in 190 schoolchildren. Families were surveyed about their children's vegetable consumption in school and at home, the use of pesticides in the home, and other sociodemographic variables. Additionally, we measured pesticide residues in vegetables and water consumed by the schoolchildren and in the soil of 14 schools. At both time points, the vegetable matrix had the highest pesticide concentration, both in urban and rural schoolchildren. The most common pesticide residues in vegetables were chlorpyrifos, diphenylamine, pyrimethanil, and thiabendazole. In the home, pyrethroid and organophosphate pesticides were mainly used in summer. Dangerous pesticide residues such as azinphos methyl and dimethoate were found in vegetables consumed by the children in schools and households, and organochlorines were found in the soil in some schools. Pesticide exposure should be limited and the health effects related to pesticide exposure should be assessed in the school population. Copyright © 2013 SESPAS. Published by Elsevier Espana.

This study aimed to investigate the prevalence of glucosuria and the characteristics of diabetes in schoolchildren as detected by a school urine glucose screening program implemented from 2010 to 2013 in the Jeonbuk province area of Korea. A total of 110 children without known diabetes were analyzed. They were checked with an oral glucose tolerance test (OGTT) with other laboratory tests and their clinical data were collected. A total of 707,238 schoolchildren from a school population of 1,064,999 were screened for glucosuria. In total, over a 4-year period, 545 schoolchildren (0.077%) were positive for glucosuria on the second urine test. The prevalence of glucosuria was more common among middle and high schoolchildren than among elementary schoolchildren. Among 110 students who completed the OGTT to confirm diabetes, 40 were diagnosed with diabetes mellitus (DM); 39 children, type 2 diabetes mellitus (T2DM) and 1 child, slowly progressive insulin dependent diabetes mellitus (SPIDDM). The mean annual incidence of diabetes was 5.6 per 100,000 schoolchildren and adolescents. The subjects with diabetes diagnosed through the urine screening test showed minimal or no symptoms of diabetes. The students with diabetes were more likely to be woman and obese, and they have a higher body mass index, higher cholesterol, triglyceride, insulin, C-peptide, and fasting glucosuria values than the students with normal glucose tolerance. We identified 40 new cases of diabetes in the Korean schoolchildren with asymptomatic glucosuria on urine glucose screening. This finding shows that school urine glucose screening is a feasible and simple method for early detection of asymptomatic T2DM. © 2017 The Korean Academy of Medical Sciences.

Whereas conventional white cassava roots are devoid of provitamin A, biofortified yellow varieties are naturally rich in β-carotene, the primary provitamin A carotenoid. We assessed the effect of consuming yellow cassava on serum retinol concentration in Kenyan schoolchildren with marginal vitamin A status. We randomly allocated 342 children aged 5-13 y to receive daily, 6 d/wk, for 18.5 wk 1) white cassava and placebo supplement (control group), 2) provitamin A-rich cassava (mean content: 1460 μg β-carotene/d) and placebo supplement (yellow cassava group), and 3) white cassava and β-carotene supplement (1053 μg/d; β-carotene supplement group). The primary outcome was serum retinol concentration; prespecified secondary outcomes were hemoglobin concentration and serum concentrations of β-carotene, retinol-binding protein, and prealbumin. Groups were compared by using ANCOVA, adjusting for inflammation, baseline serum concentrations of retinol and β-carotene, and stratified design. The baseline prevalence of serum retinol concentration <0.7 μmol/L and inflammation was 27% and 24%, respectively. For children in the control, yellow cassava, and β-carotene supplement groups, the mean daily intake of cassava was 378, 371, and 378 g, respectively, and the total daily supply of provitamin A and vitamin A from diet and supplements was equivalent to 22, 220, and 175 μg retinol, respectively. Both yellow cassava and β-carotene supplementation increased serum retinol concentration by 0.04 μmol/L (95% CI: 0.00, 0.07 μmol/L); correspondingly, serum β-carotene concentration increased by 524% (448%, 608%) and 166% (134%, 202%). We found no effect on hemoglobin concentration or serum concentrations of retinol-binding protein and prealbumin. In our study population, consumption of yellow cassava led to modest gains in serum retinol concentration and a large increase in β-carotene concentration. It can be an efficacious, new approach to improve vitamin A status. This

Objective This study was designed to evaluate the role of vitamin D, muscle fatigue biomarkers, and mechanical factors in the progression of low back pain (LBP) in schoolchildren. Background Children and adolescents frequently suffer from LBP with no clear clinical causes, and >71% of schoolchildren aged 12–17 years will show at least one episode of LBP. Materials and methods A total of 250 schoolchildren aged 12–16 years were randomly enrolled in this study. For all schoolchildren height, weight, percentage of daily sun exposure and and areas of skin exposed to sun, method of carrying the bag, and bag weight and type were recorded over a typical school week. Pain scores, physical activity (PA), LBP, serum vitamin 25(OH)D level, serum bone-specific alkaline phosphatase, creatine kinase (CK), and lactate dehydrogenase (LDH) activities and calcium (Ca) concentrations were estimated using prevalidated Pain Rating Scale, modified Oswestry Low Back Pain Disability Questionnaire, short-form PA questionnaire, and colorimetric and immunoassay techniques. Results During the period of October 2013–May 2014, LBP was estimated in 52.2% of the schoolchildren. It was classified into moderate (34%) and severe (18%). Girls showed a higher LBP (36%) compared with boys (24%). In schoolchildren with moderate and severe LBP significantly higher (P=0.01) body mass index, waist, hip, and waist-to-hip ratio measurements were observed compared with normal schoolchildren. LBP significantly correlated with less sun exposure, lower PA, sedentary activity (TV/computer use), and overloaded school bags. In addition, schoolchildren with severe LBP showed lower levels of vitamin 25(OH)D and Ca and higher levels of CK, LDH, and serum bone-specific alkaline phosphatase compared with moderate and healthy schoolchildren. Stepwise regression analysis revealed that age, gender, demographic parameters, PA, vitamin D levels, Ca, CK, and LDH associated with ~56.8%–86.7% of the incidence of LBP

Lifestyle of an individual is responsible for sixty percent of his/her state of health. Many studies of this problem indicate that in the style of life of schoolchildren, anti-health behaviours dominate over health promoting behaviours. The objective of the presented study was recognition of the lifestyle of the rural adolescents with overweight and obesity. The study covered adolescents aged 15-19, living in the rural environments of the West Pomeranian Region. Finally, the analysis covered 2,165 schoolchildren, and was performed with the use of a self-designed questionnaire form and the BMI was applied. The study showed that overweight occurred more often in the group of examined girls than boys, while obesity was twice as frequent among boys than among girls. Overweight schoolchildren (35.1%) had an adequate diet, while those obese--inadequate (78.3%). In the group of schoolchildren with overweight, passive leisure prevailed over active forms of leisure, 83.8% and 16.2%, respectively. Passive leisure was also dominant among obese respondents. Among as many as 81.8% of schoolchildren with overweight, physical activity was mediocre, while only 8.1% of them were active. The highest percentage of respondents with obesity were totally inactive physically. Obese schoolchildren relatively often experienced stressful situations. It is an alarming fact that both overweight and obese schoolchildren relatively often used psychoactive substances. A considerable number of respondents with overweight and obesity applied an adequate diet, preferred passive forms of leisure, experienced stressful situations, were characterized by low physical activity, and systematically used psychoactive substances.

Identification and assessment of COPD exacerbations.
Oliveira, A S; Munhá, J; Bugalho, A; Guimarães, M; Reis, G; Marques, A
2017-12-24
Chronic Obstructive Pulmonary Disease (COPD) exacerbations play a central role in the disease natural history of the disease, affecting its overall severity, decreasing pulmonary function, worsening underlying co-morbidities, impairing quality of life (QoL) and leading to severe morbidity and mortality. Therefore, identification and correct assessment of COPD exacerbations is paramount, given it will strongly influence therapy success. For the identification of exacerbations, several questionnaires exist, with varying degrees of complexity. However, most questionnaires remain of limited clinical utility, and symptom scales seem to be more useful in clinical practice. In the assessment of exacerbations, the type and degree of severity should be ascertained in order to define the management setting and optimize treatment options. Still, a consensual and universal classification system to assess the severity and type of an exacerbation is lacking, and there are no established criteria for less severely ill patients not requiring hospital assessment. This might lead to under-reporting of minor to moderate exacerbations, which has an impact on patients' health status. There is a clear unmet need to develop clinically useful questionnaires and a comprehensive system to evaluate the severity of exacerbations that can be used in all settings, from primary health care to general hospitals.

In order to determine the status of Enterobius vermicularis infection among schoolchildren in suburban areas of Myanmar, 761 primary schoolchildren in 3 different townships around Yangon City were subjected to a survey using cello-tape anal swabs. The subjected schoolchildren were 383 boys and 378 girls who were 5-7 years of age. Only 1 anal swab was obtained from each child. The overall egg positive rate of E. vermicularis was 47.2% (359 positives), and sex difference was not remarkable (48.6% in boys and 45.8% in girls). However, the positive rate was the highest in South Dagon (54.6%) followed by Hlaing Thayar (43.8%) and North Dagon (34.8%). This difference was highly correlated with the living standards of the people in each township. Nucleotide sequence of the 5S rDNA from the eggs on the cello-tape (2 children) revealed 99.7% identity with that of E. vermicularis reported in GenBank. The results indicated that E. vermicularis infection is highly prevalent among primary schoolchildren around Yangon, Myanmar. PMID:26797448

Mexico is considered as a nutritional transition country with a high prevalence of overweight and obesity, and recent studies have reported a high iodine intake in children. Both high iodine intake and obesity have been associated with thyroid dysfunction. Our aim was to assess iodine and salt intake and thyroid function in Mexican schoolchildren with normal weight and obesity. A cross-sectional study was performed during 2012-2013 in schoolchildren from Queretaro, Mexico. Six hundred seventy-eight schoolchildren were evaluated to obtain nutrition status, urinary iodine concentration (UIC) and thyroid volume (TVol). The prevalence of overweight and obesity was 47.3 %, the median UIC was 428 μg/L and TVol was normal in all schoolchildren; however, obese girls had a higher TVol than normal weight at the age of 8, 10 and 12 years. A subsample of schoolchildren was divided in 6-8 and 9-12-year-old groups, in order to compare thyroid function (thyrotropin, free T4, and anti-thyroid antibodies); iodine and salt intake were estimated with 24-h urinary samples. No differences in thyroid function were observed in both age groups. In the 6-8-year-old group, obese schoolchildren had higher iodine intake than normal-weight children (415.5 vs. 269.1 μg/day, p < 0.05), but no differences in salt intake. In contrast, in the 9-12-year-old group, obese schoolchildren had higher salt intake than normal-weight children (6.2 vs. 3.8 g/day, p < 0.05), but no differences in iodine intake. Dietary patterns could explain the differences between both age groups. Further studies are needed to identify the main sources of iodine intake in Mexican populations.

In the midst of the current environmental crisis, scientists, academics, authors, and politicians worldwide are urging citizens to create sustainable communities. However, there is little capability to build a sustainable society without an informed, active, and engaged populous. This requires more than just environmentally knowledgeable citizens. It requires a society that understands the principles of the environment and can also exemplify them in daily life. In order to create a more environmentally literate world, there has been a push for environmental education integrated into schools. This qualitative study sought to examine Kenyan teachers' perspectives on the human-nature interaction by conducting vignette focus-group interviews. It is a subject not widely explored but vital for conservation not only in this area, but also other areas that seek to have an ecological informed populous. The vignettes were created using photographs and explanations of the photographs that the participants collected and emailed to the authors. For the focus-group vignette interviews, there were a total of 55 participants (30 females and 25 males). After InVivo analysis, we had 6 codes (resentment, pride, perils, blame, pragmatism, and self-interested) within 3 major themes. This study has implications for informing science education to combat these traditions of subjecting students to a science curriculum that demotes Kenyan cultural heritage and lifestyle. By incorporating local knowledge such as the ideas discussed in this paper into Kenyan science education, Kenyans can reach one of most challenging objectives of education, which is to produce children who are fundamentally aware of their environment.

Background Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation. Cardiovascular-related comorbidities are established to contribute to morbidity and mortality especially during exacerbations. The aim of the current study was to determine alterations in hemorheology (erythrocyte aggregation, deformability) in newly diagnosed COPD patients and their response to medical treatment and to compare with values of COPD patients with exacerbations. Materials and Methods The study comprised 13 COPD patients, 12 controls, and 16 COPD patients with exacerbations. The severity of COPD was determined according to Global Initiative for Chronic Obstructive Lung Disease guidelines. Red blood cell (RBC) deformability and aggregation were measured by an ektacytometer. Results RBC deformability of COPD patients with exacerbations was decreased compared to the other groups. Erythrocyte aggregation and plasma fibrinogen of COPD patients determined during exacerbations were higher than control. Conclusion Decreased RBC deformability and increased aggregation associated with exacerbations of COPD may serve as unfavorable mechanisms to worsen oxygenation and thus clinical symptoms of the patient. Treatment modalities that modify rheological parameters might be beneficial. PMID:29089816

Background Group A streptococcus (GAS) pharyngitis is associated with high rates of rheumatic heart disease (RHD) in developing countries. We sought to identify guidelines for empiric treatment of pharyngitis in low resource settings. To inform the design of GAS vaccines, we determined the emm types associated with pharyngitis among African schoolchildren. Methods Surveillance for pharyngitis was conducted among children 5 to 16 years of age attending schools in Bamako, Mali. Students were encouraged to visit a study clinician when they had a sore throat. Enrollees underwent evaluation and throat swab for isolation of GAS. Strains were emm typed by standard methods. Results GAS was isolated from 449 (25.5%) of the 1,759 sore throat episodes. Painful cervical adenopathy identified 403 children (89.8%) with GAS infection and was absent in 369 uninfected children (28.2%). Emm type was determined in 396 (88.2%) of the 449 culture-positive children; 70 types were represented and 14 types accounted for 49% of isolates. Based on the proportion of the 449 isolates bearing emm types included in the 30-valent vaccine (31.0%) plus non-vaccine types previously shown to react to vaccine-induced bactericidal antibodies (44.1%), the vaccine could protect against almost 75% of GAS infections among Bamako schoolchildren. Conclusions Two promising strategies could reduce RHD in low resource settings. Administering antibiotics to children with sore throat and tender cervical adenopathy could treat most GAS-positive children while reducing use of unnecessary antibiotics for uninfected children. Broad coverage against M types associated with pharyngitis in Bamako schoolchildren might be achieved with the 30-valent GAS vaccine under development. PMID:25356953

The historical Japanese influenza vaccination program targeted at schoolchildren provides a unique opportunity to evaluate the indirect benefits of vaccinating high-transmitter groups to mitigate disease burden among seniors. Here we characterize the indirect mortality benefits of vaccinating schoolchildren based on data from Japan and the US. We compared age-specific influenza-related excess mortality rates in Japanese seniors aged ≥65 years during the schoolchildren vaccination program (1978-1994) and after the program was discontinued (1995-2006). Indirect vaccine benefits were adjusted for demographic changes, socioeconomics and dominant influenza subtype; US mortality data were used as a control. We estimate that the schoolchildren vaccination program conferred a 36% adjusted mortality reduction among Japanese seniors (95%CI: 17-51%), corresponding to ∼1,000 senior deaths averted by vaccination annually (95%CI: 400-1,800). In contrast, influenza-related mortality did not change among US seniors, despite increasing vaccine coverage in this population. The Japanese schoolchildren vaccination program was associated with substantial indirect mortality benefits in seniors.

Post-war socio-economic changes in Croatia probably affected dietary habits, and dietary data about schoolchildren after the war are missing. The aim of the study was to compare current nutrient intakes and dietary behavior between urban and rural schoolchildren in Croatia. A completely quantified Food Frequency Questionnaire was used. Subjects were 315 urban and 163 rural schoolchildren. Mean age was 12.5 and 12.6 years in the urban and rural area, respectively. Consumption of fast food, soft drinks and alcohol was more prevalent and more linked with dietary behavior in the urban than in the rural area. In both living areas protein intake was excessive (in the urban area 38.1% of subjects and in the rural 36.2% of subjects had protein intake higher than 200% RDA). Under 75% RDA/DRI in both living areas was observed for vitamin D, folate, calcium and selenium. Micronutrient intakes negatively correlated with age in both living areas, but were more pronounced in the urban area. The urban sample had more adequate energy and nutrient intakes which is consistent with prewar findings.

Background The design and development of school health programmes will require information at demographic characteristics of schoolchildren and the major health burdens of the school-age group, the opportunities for intervention and the appropriateness of the available infrastructure. This study aims to analyse demographic and parasitic infections status of schoolchildren and sanitary conditions of schools in Sanliurfa province of south-eastern Turkey. Method Three primary schools were randomly selected in the shantytown, apartment and rural districts. A total of 1820 schoolchildren between 7–14 years age were took part to the survey of whom 1120 (61.5%) were boys and 700 (38.4%) were girls. A child form (including child's name, sex, age, school grade and parasitic infections) and school survey form (including condition of water supply, condition of latrines, presence of soaps on the basins and presence of garbage piles around to the schools) were used for demographic, parasitic and sanitary surveys. Stool samples were examined by cellophane thick smear technique for the eggs of intestinal helminths. Results The demographic survey showed that number of schoolchildren was gradually decreased as their age's increase in shantytown school. The sex ratio was proportional until the second grade, after which the number of females gradually decreased in children in shantytown and rural schools while, in apartment area, schoolchildren was proportionally distributed between age groups and gender even the high-grade students. The prevalence of helminthic infections was %77.1 of the schoolchildren in shantytown, 53.2% in apartment district and 53.1% of rural area. Ascaris lumbricoides was the most prevalent species and followed by Trichuris trichiura, Hymenolepis nana and Taenia species in three schools. Sanitation survey indicated that the tap water was limited in shantytown school, toilet's sanitation was poor, available no soaps on lavatories and garbage piles were

Several factors have been accused for asthma exacerbations, however, very few studies have evaluated whether different factors predict severity of asthma exacerbation. We aimed to determine the predictive factors for severity of asthma exacerbation. Retrospective analysis of data on 93 patients visited our emergency-department because of asthma exacerbation was reviewed. Hospitalization in intensive care unit and/or intubation because of asthma was accepted as the criteria for severe exacerbation. Logistic regression analysis estimated the strength of association of each variable, potentially related to severe asthmatic exacerbation, with severe/very severe as compared to mild/moderate asthmatic exacerbation. Independent variables included in the analysis were age, sex, smoking history, inhaler steroid using, compliance with medication, chronic asthma severity, presence of additional atopic diseases, prick test positivity, provocative factors, number of short-acting beta(2)-agonist using, number of visits to emergency department for asthma over one year period, previous severe exacerbation, pulmonary functions, and blood eosinophil count. 20 were severe/very severe and 73 mild/moderate asthmatic exacerbation. Frequent using of short-acting beta(2)-agonist (OR= 1.5, 95% CI= 1.08-5.3, p= 0.003), noncompliance with medication (OR= 3.6, 95% CI= 1.3-9.9, p= 0.013), previous severe asthmatic exacerbation (OR= 3.8, 95% CI= 1.48-10.01, p= 0.005) and recent admission to hospital (OR= 2.9, 95% CI= 1.07-8.09, p= 0.037) were found to be predictive factors for severe asthmatic exacerbation. Different predictive factors, in particular frequent using of short-acting beta(2)-agonist and noncompliance with medication may be associated with severe asthma exacerbations compared to milder exacerbations. This suggests different mechanisms are responsible for severity of asthma exacerbation.

We empirically examine the reporting on biotechnology in Kenyan and international newspapers between 2010 and early 2014. We identify news articles that reported on biotechnology and analyze their use of words to determine whether there is a balance in the reporting of perceived risks and benefits. We also consider how the sources used in news articles and how the publication of the Séralini study of rats fed genetically modified maize affect the balance of reporting of perceived risks and benefits. We find that in Kenyan news reporting, more articles mention perceived benefits than risks, but when risks are mentioned, new articles contain more references to risks than to benefits. We also find that sources affect the reporting of perceived risks and benefits and that the Séralini study increased the likelihood that perceived risks are reported in Kenyan news reporting, but not in international newspapers. © The Author(s) 2015.
Civil unrest and birthweight: an exploratory analysis of the 2007/2008 Kenyan Crisis.

For decades, Africa has been plagued by political and ethnic conflict, the health ramifications of which are often not investigated. A crisis occurred recently in Kenya following the 2007 presidential election. Ethnic violence ensued, targeting the incumbent President Kibaki's Kikuyu people. The violence occurred primarily in Nairobi and the Rift Valley of Kenya. We sought to examine the association between exposure to the 2007/2008 Kenyan Crisis and birthweight. Using the 2008/2009 Kenyan Demographic and Health Survey (KDHS), we compared birthweights of infants in utero or not yet conceived during the 15 months after the political turmoil following the 2007 presidential election (exposed) to those who were born before the crisis (unexposed). There were 663 "exposed" and 687 "unexposed" infants. Multivariate regression was used. We examined the possibility of two-way and three-way interactions between exposure status, ethnicity (Kikuyu versus non-Kikuyu), and region (violent region versus not). Overall, exposure to the Kenyan Crisis was associated with lower birthweight. Kikuyu women living in a violent region who were exposed during their 2nd trimester had the greatest difference in birthweight in comparison to all unexposed infants: 564.4g lower (95% CI 285.1, 843.6). Infants of Kikuyu exposed during the 2nd trimester and living in a violent region weighed 603.6g less (95% CI 333.6, 873.6) than Kikuyu infants born during the unexposed period. Political unrest may have implications for the birthweight of infants, particularly among targeted populations. Given the adverse sequelae associated with lowered birthweight, these results suggest that particular attention should be paid to pregnant women and targeted ethnic groups following such events.

The aim of this study was to determine the influence of perception of the environment in physical activity habits of schoolchildren (aged 9-11 years) in the province of Cuenca, Spain. Using a phenomenological perspective drawings were analyzed individual about their environment and places you normally would from a purposive sample of 32 students of 4th and 5th year of primary education. These same students participated in seven focus groups with a script aimed to obtain information on their perception of the environment and its influence on physical activity habits. After analyzing four categories emerged: residence, urban configuration, displacements/commuting and sense of belonging or membership to the neighborhood. The students perceived that reside in gated communities or in rural areas facilitates physical activity of schoolchildren, while residing in neighborhoods and cities less accessible, feeling of insecurity traffic, make car journeys, and the sense of not belonging or membership to the neighborhood were perceived by children as barriers to being active. The perception of the environment influences physical activity habits of schoolchildren in the province of Cuenca. Changes in physical activity patterns of schoolchildren cannot take place without considering the context in which the individual exists, so specific strategies are needed that take into account the urban environment to promote physical activity of schoolchildren.

Germain, Adrienne; Smock, Audrey
Kenya and Ghana provide interesting case studies of the theory that women who have access to roles other than mother and whose status does not depend largely or solely on the number of children they bear will have fewer children. Kenyan and Ghanaian women have among the highest desired and actual fertility in the world. They also, relatively…

Low enrollment of women in higher education is a problem in Africa, particularly in Kenya, where despite the government's introduction of affirmative action, female enrollment averages only 36.7% at public universities. This gender gap may be due to the patriarchal influence in Kenyan society, where the role of women is seen as child-bearing,…

Use of the internet and videogames by children and adolescents has risen dramatically over the last decade. Increasing evidence of internet and videogame addiction among children is causing concern due to its harmful physical, emotional and social consequences. There is also emerging evidence for an association between computer and videogame addiction and attention deficit/hyperactivity disorder (ADHD). To investigate the relationship between ADHD and internet addiction. We compared 50 male schoolchildren, mean age 13 years, diagnosed with ADHD to 50 male schoolchildren without ADHD on measures of internet addiction, internet use and sleep patterns. Children with ADHD had higher scores on the Internet Addiction Test (IAT), used the internet for longer hours, and went to sleep later than those without ADHD. These findings indicate an association of ADHD, sleep disorders and internet/videogame addiction.

We investigated the impact of Cardio-Pulmonary Resuscitation (CPR) instruction by children on the attitude of people to perform bystander CPR. In 2012, children from primary and secondary school (age span 11–13 years) received a free individual CPR training package containing an inexpensive manikin and a training video. After a CPR training session by their class teacher, they were invited to teach their relatives and friends. After the training, the trainees of the children were invited to participate in a web survey, containing a test and questions about prior CPR training and about their attitude towards bystander CPR (BCPR) before and after the training. We measured the impact on the attitude to perform BCPR and the theoretical knowledge transfer by the children. A total of 4012 training packages were distributed to 72 schools of which 55 class teachers subscribed their students (n = 822) for the training programme for relatives and friends. After a validation procedure, 874 trainees of 290 children were included in the study. In comparison to trainees of secondary schoolchildren, trainees of primary schoolchildren scored better for the test as well as for a positive change of attitude towards future BCPR (P < 0.001). For every child-instructor 1.7 people changed their attitude towards BCPR positively. Instructing schoolchildren to teach their relatives and friends in Basic Life Support (BLS) led to a more positive attitude towards BCPR. The results were more positive with trainees from primary schoolchildren than with trainees from secondary schoolchildren.

Kenya has one of the highest adolescent fertility rates in East-Africa, estimated at 106 births per 1000 females aged 15-19years. In addition to promoting safe sexual behaviour, utilisation of maternal health services (MHS) is essential to prevent poor outcomes of pregnancy and childbirth. To ensure optimum planning, particularly in the context of the Sustainable Development Goals, this study assesses the current service utilisation patterns of Kenyan adolescent mothers and the factors that affect this utilisation. Using data from the recently published 2014 Kenya Demographic Health Survey, we collected demographic and utilisation data of all three MHSs (antenatal care (ANC), skilled birth attendance (SBA) and postnatal care (PNC)) of adolescent mothers aged 15-19years. We then conducted bivariate and multivariate analyses to test associations between selected demographic and service utilisation variables. Our findings showed that half of Kenyan adolescent mothers have had their first birth by the age of 16. MHS utilisation rates amongst Kenyan adolescent mothers were 93%, 65%, 92% for ANC, SBA and PNC respectively. Mother's education, religion, ethnicity, place of residence, wealth quintile, mass media exposure, and geographical region were significant predictors for both ANC and SBA utilisation. Education level of partner was significant for ANC utilisation while parity was significant for both SBA and PNC. Adolescent MHS utilisation is not optimum in Kenya. More work that includes affordable care provision, cultural re-orientation, targeted mass-media campaigns and male involvement in care need to be done with emphasis on the most disadvantaged areas.

The question of a causative interrelation between air pollution and respiratory status has received considerable attention by the mass media in our country. Schoolchildren aged 7 to 11 living in two communities with different levels of air pollution were studied. The parents of these children filled out a health questionnaire. The prevalence of respiratory symptoms and pulmonary diseases was found to be significantly higher among children growing up in the polluted area (Tirnaveni) as compared with the low-pollution area (Dej). Lung function tests point out FEF25-75 disorders (and other lung disorders) at higher frequencies in schoolchildren living in the polluted area. Over 90% of schoolchildren living in the polluted area. Over 90% of schoolchildren with lung function disorders had a positive response to bronchodilatation. Of the schoolchildren with lung function disorders, 75.47% (p < 0,001) were atopic all of whom were sensitized to the down and house-dust.

Intestinal parasitic infections (IPIs) among schoolchildren in Republic of Marshall Islands (RMI) largely remains unknown, thus investigation on IPIs status to establish the baseline data is urgently needed. This cross-sectional study intended to investigate the current IPIs status and associated risk factors among schoolchildren at capital of RMI. Single stool sample from 400 schoolchildren (207 boys and 193 girls) aged 9.73±2.50 yrs old was examined by employing merthiolate-iodine-formaldehyde concentration method. Demographic characteristics, uncomfortable symptoms and risk factors were obtained by questionnaires investigation. The overall prevalence of IPIs in schoolchildren was 22.8% (91/400), of them 24.2% harbored at least 2 different parasites. Notably, the majority was infected by waterborne protozoan parasites (82.4%, 75/91). Nine different intestinal parasites have been identified, of which six were pathogenic including Hook worm, Trichuris trichiura, Enterobius vermicularis, Entamoeba histolytica/dispar, Giardia intestinalis and Blastocystis hominis. Schoolchildren who ever complained dizziness or headache showed a significant higher prevalence of pathogenic IPIs than those who did not (p<0.05). Schoolchildren who lived in urban area than rural area had higher chance to acquire pathogenic IPIs (p=0.03). However, none of risk factors were identified to be associated with pathogenic IPIs.

Schoolchildren with Learning Difficulties Have Low Iron Status and High Anemia Prevalence
Arcanjo, C. P. C.; Santos, P. R.
2016-01-01
Background. In developing countries there is high prevalence of iron deficiency anemia, which reduces cognitive performance, work performance, and endurance; it also causes learning difficulties and negative impact on development for infant population. Methods. The study concerns a case-control study; data was collected from an appropriate sample consisting of schoolchildren aged 8 years. The sample was divided into two subgroups: those with deficient initial reading skills (DIRS) (case) and those without (control). Blood samples were taken to analyze hemoglobin and serum ferritin levels. These results were then used to compare the two groups with Student's t-test. Association between DIRS and anemia was analyzed using odds ratio (OR). Results. Hemoglobin and serum ferritin levels of schoolchildren with DIRS were statistically lower when compared to those without, hemoglobin p = 0.02 and serum ferritin p = 0.04. DIRS was statistically associated with a risk of anemia with a weighted OR of 1.62. Conclusions. In this study, schoolchildren with DIRS had lower hemoglobin and serum ferritin levels when compared to those without. PMID:27703806

The goal of this study was to explore attitudes and habits of Serbian preschool and school children in consumption of meat products, milk and milk products, eggs and egg products and honey and bee products. The survey was conducted on a sample of 227 children, divided into three different age groups: preschool (ages 4-6), primary school I-IV grade (ages 7-11) and primary school V-VIII grade (ages 12-15). The results showed that all examined groups of children consumed meat products, milk and milk products, eggs and egg products, and honey and bee products. In all groups of children, the most frequently consumed food (among our food category choices) was dried ham (consumed by 19.64% of preschool children; 23.75% of schoolchildren from I-IV grade; 19.74% of schoolchildren from V-VIII grade). Fewer preschool children consumed sterilized milk compared to children of school age. The results showed that in all three groups of children, the most commonly consumed milk products were yoghurt (from 12.20 to 15.29% of children consumed these) and sour cream (from 11.57 to 12.74% of children consumed this), while kefir was the least-consumed product. In addition, there was no difference in consumption of boiled or fried eggs in the examined groups of children, while the consumption of egg products (mayonnaise) was higher in the group of preschool children than in the group of schoolchildren from V-VIII grade. Preschool children consumed honey 14.99% more often than schoolchildren from I-IV grade, and 14.49% more often than did schoolchildren from grade V-VIII.

2015-01-01
Background: Studies from the West have demonstrated that ready-to-eat cereals (RTECs) are a common form of breakfast and more likely to be consumed by children. This study aimed to investigate the breakfast eating pattern and RTECs consumption among schoolchildren in Kuala Lumpur. Methods: In this cross-sectional study, a total of 382 schoolchildren, aged 10 and 11 years old, were recruited from seven randomly selected primary schools in Kuala Lumpur. Information on socio-demographics, breakfast eating patterns, and perceptions of RTECs and dietary intake (24-hour dietary recalls) were obtained. Results: Among the respondents, only 22% of them consumed breakfast on a regular basis. The most commonly eaten food by children at breakfast was bread (27.2%), followed by biscuits (22.2%) and RTECs (20.5%). The majority of them (93%) reported that they consumed RTECs sometimes during the week. Chocolate RTECs (34.1%), corn flake RTECs (30.3%), and RTECs coated with honey (25.1%) were the most popular RTECs chosen by children. Respondents who consumed RTECs showed a significantly higher intake in calories, carbohydrate, vitamin A, vitamin B1, vitamin B2, vitamin B3, folate, vitamin C, calcium, iron, and fibre (P < 0.05), compared to those who skipped breakfast and those who had breakfast foods other than RTECs. Conclusion: The lower levels of breakfast consumption among schoolchildren in Kuala Lumpur need serious attention. RTEC is a nutritious food which is well accepted by a majority of the schoolchildren in Kuala Lumpur. Nutrition intervention should be conducted in the future to include a well-balanced breakfast with the utilisation of RTECs for schoolchildren. PMID:25892948

The Kenyan Ministry of Public Health and Sanitation was the first in Africa to introduce the new 10-valent Pneumococcal Conjugate Vaccine, PCV-10, in 2011. For successful implementation and to avoid adverse events following immunisation, specific training on handling and storage of the PCV-10 vaccine was required. Therefore, a training DVD was recorded in English and partly in Kiswahili to be used in combination with in-classroom training. Since the Kenyan Immunisation Programme was the first to use a DVD for training healthcare workers, an evaluation was done to obtain feedback on content, format and use, and propose suggestions to improve quality and uptake of the DVD. Feedback was obtained from nurses and vaccinology course participants through the completion of a questionnaire. Nurses also participated in focus group discussions and trainers in key informant interviews. Twelve trainers, 72 nurses and 26 international vaccinology course participants provided feedback, with some notable differences between the three study groups. The survey results confirmed the acceptability of the content and format, and the feasibility of using the DVD in combination with in-classroom teaching. To improve the quality and adoption of the DVD, key suggestions were: Inclusion of all EPI vaccines and other important health issues; broad geographic distribution of the DVD; and bilingual English/Kiswahili use of languages or subtitles. The Kenyan DVD is appreciated by a heterogeneous and international audience rendering the DVD suitable for other Anglophone African countries. Differences between feedback from nurses and vaccinology course participants can be explained by the practical approach of the DVD and the higher education and service level of the latter. A drawback is the use of DVD players and televisions due to lack of electricity, but it is a matter of time before all rural health facilities in Africa will have access to electricity and modern technology.

Recent studies have demonstrated the activation of coagulation pathways in asthmatic airways. This study aimed to determine systemic blood coagulation during asthma exacerbation compared with the stable state in children. Pediatric patients (aged between 5 and 15 years) suffering from asthma exacerbation were enrolled. von Willebrand factor (vWF), plasminogen activator inhibitor type-1 (PAI-1), protein C, D-dimer, prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin complex (TAT), and C-reactive protein (CRP) levels were measured during asthma exacerbation and stable state. A total of 22 patients were enrolled. The median vWF, PAI-1, and CRP during asthma exacerbation were significantly higher than those of the stable state: 147.5% (interquartile range, IQR: 111.05-196.57) versus 94% (IQR: 69.72-109.62, p < 0.001), 41.9 ng/ml (IQR: 21.91-48.61) versus 26.17 ng/ml (IQR: 15.89-34.44, p < 0.03), and 4.46 mg/l (IQR: 2.15-16.23) versus 0.87 mg/l (IQR: 0.20-3.89, p < 0.015), respectively. However, the median protein C during asthma exacerbation was significantly lower than that of the stable state: 99.5% (IQR: 86.75-117) versus 113% (IQR: 94-115.25), p = 0.01. No significant difference was found between the levels of D-dimer, F1 + 2, and TAT during asthma exacerbation and stable state. Ultimately, D-dimer was positively correlated with asthma exacerbation score (R = 0.466, p = 0.027). A significant correlation was observed between vWF and CRP (R = 0.527, p = 0.012). Evidence was found of increased endothelial activation and increased PAI-1 during asthma exacerbation. This may emphasize the potential role of blood coagulation in asthma exacerbation. © 2016 S.

Scabies is a major global public health issue that might affect people from all socioeconomic levels. The primary contributing factors in contracting scabies seem to be poverty and overcrowded living conditions. Scabies often spreads among schoolchildren quite rapidly, owing to their close contact and overcrowding within the schools. However, limited information is available about its risk factors and the socioeconomic correlates among schoolchildren in Egypt. This study aimed to assess the prevalence of scabies and its risk factors among primary schoolchildren in Kafr El-Sheikh administrative area, Egypt. This cross-sectional descriptive study was performed on primary schoolchildren in urban and rural areas of Kafr El-Sheikh administrative area. A predesigned questionnaire was used for data collection from the randomly selected 2,104 children, and clinical dermatological examination was done for them. Out of 2,104 children studied, there were 92 cases of scabies with a prevalence of 4.4%. The prevalence of scabies infestation in male students was 3.9%, while it was 4.8% in females, with no statistical significance. The results showed significant variations in the risk of scabies infestation by factors such as residence, paternal education and occupation, maternal education, sleeping with others, having animals at home, dealing with animals outside the house, type of building for living, family history of itchy rash, and sharing clothes with others. In our community, scabies is still an important health problem affecting schoolchildren, especially in rural areas. It is characterized by a complex web of causation, particularly poor living conditions and low level of parents' education.

To investigate any association between dental erosion and its potential dietary risk factors in a group of schoolchildren in Benghazi, Libya. A cross-sectional observational study. A random sample of 12-year-old schoolchildren in 36 randomly selected schools completed a questionnaire to provide dietary data and underwent dental examination. Dental erosion was assessed using UK National Diet and Nutrition Survey (2000) criteria. Associations between erosion and dietary variables under study were investigated through processes of bivariate and multivariate analyses. Of 791 schoolchildren dentally examined, 40.8% had dental erosion; erosion into enamel affecting 32.5%, into dentine affecting 8% and into pulp affecting 0.3% of subjects. Bivariate analysis showed frequency of fruit-based sugary drink intake was statistically significantly and positively associated with erosion (p=0.006, Odds Ratio; 1.498, 95% CI; 1.124, 1.996) as was the length of time taken to consume acidic drinks (p≠0.005, Odds Ratio; 1.593, 95%CI; 1.161, 2.186). Additionally, multivariate analysis showed frequency of consumption of fruit other than bananas, sugared tea with milk and flavoured milk to also be positively associated with erosion (p=<0.05). In this group of Libyan 12-year-olds, frequency of consumption of fruit-based sugary drinks and length of time taken to consume acidic drinks were the primary statistically significant positive risk factors for dental erosion.

Prenatal exposure to antibacterials may permanently dysregulate fetal metabolic patterns via epigenetic pathways or by altering maternal microbiota. We examined the association of prenatal exposure to systemic antibacterials with overweight and obesity in schoolchildren. We conducted a prevalence study among Danish schoolchildren aged 7-16 years using data from routine school anthropometric evaluations conducted during 2002-2013. Prenatal exposure to antibacterials was ascertained by using maternal prescription dispensations and infection-related hospital admissions during pregnancy. We defined overweight and obesity among the children using standard age- and sex-specific cutoffs. We computed sex-specific adjusted prevalence ratios (aPRs) of overweight and obesity associated with exposure to prenatal antibacterials, adjusting for maternal age at delivery, marital status, smoking in pregnancy and multiple gestation; we also stratified the analyses by birth weight. Among 9886 schoolchildren, 3280 (33%) had prenatal exposure to antibacterials. aPRs associated with the exposure were 1.26 (95% confidence interval (CI): 1.10-1.45) for overweight and 1.29 (95% CI: 1.03-1.62) for obesity. Among girls, aPRs were 1.16 (95% CI: 0.95-1.42) for overweight and 1.27 (95% CI: 0.89 to 1.82) for obesity. Among boys, aPRs were 1.37 (95% CI: 1.13-1.66) for overweight and 1.29 (95% CI: 0.96-1.73) for obesity. The aPR for overweight was higher among schoolchildren with birth weight <3500 g (aPR: 1.30, 95% CI: 1.05-1.61) than in schoolchildren with birth weight ⩾3500 g (aPR: 1.18, 95% CI: 0.95-1.46). Inversely, the association for obesity was higher among schoolchildren with birth weight ⩾3500 g (aPR: 1.35, 95% CI: 1.00-1.81) than among those who were <3500 g at birth (aPR: 1.16, 95% CI: 0.82-1.65). Prenatal exposure to systemic antibacterials is associated with an increased risk of overweight and obesity at school age, and this association varies by birth weight.

To assess the ability of schoolchildren to use a automated external defibrillator (AED) to provide an effective shock and their retention of the skill 1 month after a training exercise supported by audiovisual materials. Quasi-experimental controlled study in 205 initially untrained schoolchildren aged 6 to 16 years old. SAEDs were used to apply shocks to manikins. The students took a baseline test (T0) of skill, and were then randomized to an experimental or control group in the first phase (T1). The experimental group watched a training video, and both groups were then retested. The children were tested in simulations again 1 month later (T2). A total of 196 students completed all 3 phases. Ninety-six (95.0%) of the secondary school students and 54 (56.8%) of the primary schoolchildren were able to explain what a SAED is. Twenty of the secondary school students (19.8%) and 8 of the primary schoolchildren (8.4%) said they knew how to use one. At T0, 78 participants (39.8%) were able to simulate an effective shock. At T1, 36 controls (34.9%) and 56 experimental-group children (60.2%) achieved an effective shock (P< .001). At T2, 53 controls (51.4%) and 61 experimental-group children (65.6%) gave effective shocks (P=.045). All the students completed the tests in 120 seconds. Their average times decreased with each test. The secondary school students achieved better results. Previously untrained secondary school students know what a AED is and half of them can manage to use one in simulations. Brief narrative, audiovisual instruction improves students' skill in managing a SAED and helps them retain what they learned for later use.

To investigate the annual incidence of myopia and associated factors among young schoolchildren in Taipei City. The Myopia Investigation Study in Taipei was a citywide, population-based cohort study. During the fall 2013 semester (baseline), a total of 11,590 grade 2 schoolchildren completed ocular examination and were included for further analysis. A parent-completed questionnaire was administered to collect data on risk factors for myopia development. Follow-up visits were arranged biannually over 3 years. The first-year results are reported here. Schoolchildren who were emmetropic/hyperopic at baseline and had myopia (spherical equivalent ≤ -0.5 diopters) in either eye at follow-up were identified as having incident myopia. Among 7376 baseline nonmyopic participants, 6794 (92.1%) were examined during the first-year follow-up, and 1856 (25.2%) with incident myopia were identified. The incidence density of myopia was 31.7 (95% confidence interval [CI]: 30.6-32.8) per 100 person-years. Cox hazard proportional regression analysis revealed that participants who were emmetropic at baseline (hazards ratio [HR]: 19.37; 95% CI: 4.84-77.57), who had two myopic parents (HR: 1.21; 95% CI: 1.04-1.42), and who spent ≥5 hours every week on after-school tutoring programs (HR: 1.12; 95% CI: 1.02-1.22) had greater risk for incident myopia. By contrast, protective factors included suburban area of residence (HR: 0.91; 95% CI: 0.83-1.00) and spending ≥30 minutes outdoors after school every weekday (HR: 0.90; 95% CI: 0.82-0.99). This study provides population-based data on the annual incidence of myopia among Taiwanese schoolchildren, and found that baseline refractive status, parental myopia, area of residence, time outdoors after school on weekdays, and time spent on after-school tutoring programs are associated with risk of new-onset myopia.

Exacerbations affect morbidity in chronic obstructive pulmonary disease (COPD). We sought to evaluate the association between exacerbation frequency and spirometric and health status changes over time using data from a large, long-term trial. This retrospective analysis of data from the 4-year UPLIFT (Understanding Potential Long-term Impacts on Function with Tiotropium) trial compared tiotropium with placebo. Annualized rates of decline and estimated mean differences at each time point were analyzed using a mixed-effects model according to subgroups based on exacerbation frequency (events per patient-year: 0, >0-1, >1-2, and >2). Spirometry and the St George's Respiratory Questionnaire (SGRQ) were performed at baseline and every 6 months (also at one month for spirometry). In total, 5992 patients (mean age 65 years, 75% male) were randomized. Higher exacerbation frequency was associated with lower baseline postbronchodilator forced expiratory volume in one second (FEV(1)) (1.40, 1.36, 1.26, and 1.14 L) and worsening SGRQ scores (43.7, 44.1, 47.8, and 52.4 units). Corresponding rates of decline in postbronchodilator FEV(1) (mL/year) were 40, 41, 43, and 48 (control), and 34, 38, 48, and 49 (tiotropium). Values for postbronchodilator forced vital capacity decline (mL/year) were 45, 56, 74, and 83 (control), and 43, 57, 83, and 95 (tiotropium). The rates of worsening in total SGRQ score (units/year) were 0.72, 1.16, 1.44, and 1.99 (control), and 0.38, 1.29, 1.68, and 2.86 (tiotropium). The proportion of patients who died (intention-to-treat analysis until four years [1440 days]) for the entire cohort increased with increasing frequency of hospitalized exacerbations. Increasing frequency of exacerbations worsens the rate of decline in lung function and health-related quality of life in patients with COPD. Increasing rates of hospitalized exacerbations are associated with increasing risk of death.
COPD Exacerbation and Cholinesterase Therapy in Dementia Patients.
Mahan, Rebecca J; Blaszczyk, Amie Taggart
2016-04-01
Chronic obstructive pulmonary disease (COPD) is a nonreversible inflammatory condition of the lungs. Acetylcholine is a neurotransmitter involved in autonomic regulation of the airways, resulting in bronchoconstriction and mucous production. Cholinesterase inhibitors (ChEIs), a cornerstone therapy of dementia treatment, increase acetylcholine. Theoretically, ChEI use in patients with COPD can place patients at increased risk of exacerbation secondary to increased acetylcholine activity. A retrospective chart review was performed comparing veterans with dementia and COPD who received ChEIs with those who did not at the Veterans Affairs North Texas Health Care System. Frequency of exacerbation in the first 90 days following ChEI initiation was compared. Secondary outcomes assessed exacerbation severity and a potential protective effect of inhaled anticholinergics. A total of 94 patients were eligible for the study; 52 received a ChEI and 42 did not. The risk of exacerbation over 90 days was higher in the ChEI users with 10 (19%) experiencing an exacerbation compared with 3 (7%) in the nonusers (P = 0.133), showing a clinically significant trend. Of the patients experiencing an exacerbation, 2 patients on ChEIs had multiple exacerbations over the 90 days. The use of inhaled anticholinergics was not found to decrease the risk of exacerbation. The use of ChEIs may increase the risk of COPD exacerbation in the first 90 days of therapy in patients with dementia and COPD. This finding is clinically significant as previous studies have indicated no risk.

Viewing the Kenyan health system through an equity lens: implications for universal coverage
2011-01-01
Introduction Equity and universal coverage currently dominate policy debates worldwide. Health financing approaches are central to universal coverage. The way funds are collected, pooled, and used to purchase or provide services should be carefully considered to ensure that population needs are addressed under a universal health system. The aim of this paper is to assess the extent to which the Kenyan health financing system meets the key requirements for universal coverage, including income and risk cross-subsidisation. Recommendations on how to address existing equity challenges and progress towards universal coverage are made. Methods An extensive review of published and gray literature was conducted to identify the sources of health care funds in Kenya. Documents were mainly sourced from the Ministry of Medical Services and the Ministry of Public Health and Sanitation. Country level documents were the main sources of data. In cases where data were not available at the country level, they were sought from the World Health Organisation website. Each financing mechanism was analysed in respect to key functions namely, revenue generation, pooling and purchasing. Results The Kenyan health sector relies heavily on out-of-pocket payments. Government funds are mainly allocated through historical incremental approach. The sector is largely underfunded and health care contributions are regressive (i.e. the poor contribute a larger proportion of their income to health care than the rich). Health financing in Kenya is fragmented and there is very limited risk and income cross-subsidisation. The country has made little progress towards achieving international benchmarks including the Abuja target of allocating 15% of government's budget to the health sector. Conclusions The Kenyan health system is highly inequitable and policies aimed at promoting equity and addressing the needs of the poor and vulnerable have not been successful. Some progress has been made towards

In this paper, I use qualitative data to explore the practices engaged in by Kenyan schoolgirls to participate in modern consuming womanhood, as well as the contradictory implications of these practices for thinking about globalized mediated femininities and their enactment in resource-poor settings. The paper examines the centrality of consumption to valued modern femininity among young women around the world, as well as the structural reality of gendered access to income. I show how the cooptation of the materiality of romantic love and normative expectations of male provision in romantic relationships bridge the gap between consumption desires and economic realities among Kenyan schoolgirls in both powerful and problematic ways. The paper ends with a reflection of the implications of these findings for post-girl power, the post-feminist age and the re-inscription of patriarchy. PMID:28344428

A preliminary antiplasmodial and phytochemical screening of four Kenyan medicinal plants was carried out. The medicinal plants were extracted and tested for in vitro antiplasmodial activity against chloroquine-sensitive (K67) and chloroquine-resistant (ENT36) strains of Plasmodium falciparum. Out of 16 extracts, 12 were active against ENT36 strain while seven were active against K67 strain, that is, IC50 < or = 50 micrograms/ml. The most active extracts on both strains were those of leaves of Phyllanthus reticulatus Poir, and Suregada zanzibariensis Baill. (Euphorbiaceae) with IC50 < or = 10 micrograms/ml. The stembark of Terminalia spinosa Engl. (Combretaceae) and the stems of Dissotis brazzae Cogn. (Melastomataceae) had IC50 < or = 10 micrograms/ml for strains K67 and ENT36, respectively. A preliminary phytochemical analysis of these plants revealed the presence of different classes of primary and secondary metabolites.

Intermittent preventive treatment (IPT) is a proven malaria control strategy in infants and pregnancy. School-aged children represent 26 % of the African population, and an increasing percentage of them are scholarized. Malaria is causing 50 % of deaths in this age group and malaria control efforts may shift the malaria burden to older age groups. Schools have been suggested as a platform for health interventions delivery (deworming, iron-folic acid, nutrients supplementation, (boost-)immunization) and as a possible delivery system for IPT in schoolchildren (IPTsc). However, the current evidence on the efficacy and safety of IPTsc is limited and the optimal therapeutic regimen remains controversial. A systematic search for studies reporting efficacy and safety of IPT in schoolchildren was conducted using PubMed, Web of Science, Clinicaltrials and WHO/ICTRP database, and abstracts from congresses with the following key words: intermittent, preventive treatment AND malaria OR Plasmodium falciparum AND schoolchildren NOT infant NOT pregnancy. Five studies were identified. Most IPTsc regimes demonstrated substantial protection against malaria parasitaemia, with dihydroartemisinin-piperaquine (DP) given monthly having the highest protective effect (PE) (94 %; 95 % CI 93-96). Contrarily, SP did not provide any PE against parasitaemia. However, no IPT regimen provided a PE above 50 % in regard to anaemia, and highest protection was provided by SP+ amodiaquine (AQ) given four-monthly (50 %; 95 % CI 41-53). The best protection against clinical malaria was observed in children monthly treated with DP (97 %; 95 % CI 87-98). However, there was no protection when the drug was given three-monthly. No severe adverse events were associated with the drugs used for IPTsc. IPTsc may reduce the malaria-related burden in schoolchildren. However, more studies assessing efficacy of IPT in particular against malaria-related anaemia and clinical malaria in schoolchildren must be conducted.

The prevalence of overweight and obesity and their associated factors among schoolchildren in Manipur has not been studied. We did a cross-sectional study among 3356 schoolchildren of classes VIII to XII in Imphal West district, Manipur between September 2005 and August 2006. The characteristics of the respondents and related variables such as parental build, watching television, eating habits, playing of video/computer games and outdoor games, dietary pattern and knowledge of obesity were assessed using a questionnaire. Height, weight, waist circumference, hip circumference, fat percentage, fat mass and fat-free mass were measured. Body mass index (BMI) and waist-hip ratio for each student were calculated. The BMI of the sampled students was lower than the corresponding WHO and International Obesity Task Force standards. Using the WHO standard, the prevalence of overweight was 4.2% and of obesity 0.8%. Using multivariate logistic regression, mother being reported to be obese (OR 1.9, 95% CI 1.4-2.6), watching television for > 2 hours a day (OR 2.052, 95% CI 1.191-3.536), higher family income (OR 5.844, 95% CI 2.135-15.99), not eating other type of vegetables in the past 1 week (OR 2.338, 95% CI 1.04-5.24) and waist-hip ratio (OR 7.737, 95% CI 4.429-13.51) were found to be independent predictors of a higher BMI. Mother's literacy below class X (OR 0.6, 95% CI 0.378-0.997) and eating between major meals (OR 0.447, 95% CI 0.293-0.681) were significant predictors of a lower BMI. The prevalence of overweight and obesity among schoolchildren in the Imphal West district of Manipur is low. The possible reasons for this include a more traditional low-fat diet, less exposure to sedentary past-times and a greater time spent playing outdoors.

Rationale: Chronic obstructive pulmonary disease exacerbations are associated with disease progression, higher healthcare cost, and increased mortality. Published predictors of future exacerbations include previous exacerbation, airflow obstruction, poor overall health, home oxygen use, and gastroesophageal reflux. Objectives: To determine the value of adding blood biomarkers to clinical variables to predict exacerbations. Methods: Subjects from the SPIROMICS (Subpopulations and Intermediate Outcomes Measures in COPD Study) (n = 1,544) and COPDGene (Genetic Epidemiology of COPD) (n = 602) cohorts had 90 plasma or serum candidate proteins measured on study entry using Myriad-RBM multiplex panels. We defined total exacerbations as subject-reported worsening in respiratory health requiring therapy with corticosteroids and/or antibiotics, and severe exacerbations as those leading to hospitalizations or emergency room visits. We assessed retrospective exacerbations during the 12 months before enrollment and then documented prospective exacerbations in each cohort. Exacerbations were modeled for biomarker associations with negative binomial regression including clinical covariates (age, sex, percent predicted FEV1, self-reported gastroesophageal reflux, St. George’s Respiratory Questionnaire score, smoking status). We used the Stouffer-Liptak test to combine P values for metaanalysis. Measurements and Main Results: Between the two cohorts, 3,471 total exacerbations (1,044 severe) were reported. We identified biomarkers within each cohort that were significantly associated with a history of exacerbation and with a future exacerbation, but there was minimal replication between the cohorts. Although established clinical features were predictive of exacerbations, of the blood biomarkers only decorin and α2-macroglobulin increased predictive value for future severe exacerbations. Conclusions: Blood biomarkers were significantly associated with the occurrence of
Immune Responses in Rhinovirus-Induced Asthma Exacerbations.
Steinke, John W; Borish, Larry
2016-11-01
Acute asthma exacerbations are responsible for urgent care visits and hospitalizations; they interfere with school and work productivity, thereby driving much of the morbidity and mortality associated with asthma. Approximately 80 to 85 % of asthma exacerbations in children, adolescents, and less frequently adults are associated with viral upper respiratory tract viral infections, and rhinovirus (RV) accounts for ∼60-70 % of these virus-associated exacerbations. Evidence suggests that it is not the virus itself but the nature of the immune response to RV that drives this untoward response. In particular, evidence supports the concept that RV acts to exacerbate an ongoing allergic inflammatory response to environmental allergens present at the time of the infection. The interaction of the ongoing IgE- and T cell-mediated response to allergen superimposed on the innate and adaptive immune responses to the virus and how this leads to triggering of an asthma exacerbation is discussed.

Background/objectives Scabies is a major global public health issue that might affect people from all socioeconomic levels. The primary contributing factors in contracting scabies seem to be poverty and overcrowded living conditions. Scabies often spreads among schoolchildren quite rapidly, owing to their close contact and overcrowding within the schools. However, limited information is available about its risk factors and the socioeconomic correlates among schoolchildren in Egypt. This study aimed to assess the prevalence of scabies and its risk factors among primary schoolchildren in Kafr El-Sheikh administrative area, Egypt. Methods This cross-sectional descriptive study was performed on primary schoolchildren in urban and rural areas of Kafr El-Sheikh administrative area. A predesigned questionnaire was used for data collection from the randomly selected 2,104 children, and clinical dermatological examination was done for them. Results Out of 2,104 children studied, there were 92 cases of scabies with a prevalence of 4.4%. The prevalence of scabies infestation in male students was 3.9%, while it was 4.8% in females, with no statistical significance. The results showed significant variations in the risk of scabies infestation by factors such as residence, paternal education and occupation, maternal education, sleeping with others, having animals at home, dealing with animals outside the house, type of building for living, family history of itchy rash, and sharing clothes with others. Conclusion In our community, scabies is still an important health problem affecting schoolchildren, especially in rural areas. It is characterized by a complex web of causation, particularly poor living conditions and low level of parents’ education. PMID:25759594

The aim of the work was evaluation of efficacy of fenspiride b.i.d. on the number of exacerbations and the time to the first exacerbation in patients with chronic bronchitis. Randomized, multicentre study controlled versus placebo was carried out in 12 centers in Poland. All patients, 89 females and 68 males aged between 20 and 74, were treated with fenspiride at the dose of 160 mg/day for a period of 6 months. The following symptoms were recorded every month in order to evaluate the therapeutic efficacy: sputum quality and quantity, cough intensity, dyspnea and bronchospasm. Based on these symptoms diagnosis of exacerbation was performed according to American Thoracic Society criteria. Quality and quantity of sputum and cough significantly improved in the fenspiride group (comparing to the placebo group p= 0.027 and p = 0.049 adequately for sputum and cough). A significant difference between groups was observed in the number of exacerbation episodes and their duration. In the fenspiride group there were 0.53 episodes of exacerbation compared with 1.12 episodes in the placebo group (p = 0.038). Mean duration of exacerbation was 3.3 days in the fenspiride group and 7.3 days in the placebo treated patients (p = 0.034). Time to the first exacerbation differed between groups, but this difference was not statistically significant. Number of side effects observed did not differ between groups. Fenspiride treatment was assessed as relatively effective in terms of influence on exacerbations, and well tolerated during six month therapy.

To evaluate the association between sports activities and allergic symptoms, especially rhinitis, among schoolchildren. This longitudinal survey of schoolchildren collected data from questionnaires regarding allergic symptoms based on the International Study of Asthma and Allergies in Childhood (ISAAC) program and sports participation that were distributed to the parents of children at all 12 public primary schools in Ohmi-Hachiman City, Shiga Prefecture, Japan. Data were collected annually from 2011 until 2014, when the children reached 10 years of age. Blood samples were obtained in 2014, and the levels of immunoglobulin (Ig)E specific to four inhalant allergens were measured. Data from 558 children were analyzed. At 10 years of age, prevalence of asthma and eczema did not differ significantly, while rhinitis was significantly higher (p = 0.009) among children who participated in sports. Prevalence of rhinitis increased as the frequency or duration of sports participation increased (p < 0.01). The prevalence of new-onset rhinitis increased significantly among 10-year-olds with increasing duration of participation in sports (p = 0.03). Among those who participated in continuous sports activities, the prevalence of rhinitis was significantly higher with prolonged eczema (p = 0.006). Sports activities did not increase sensitization to inhalant allergens. Sports activities enhance the prevalence of rhinitis in schoolchildren. Prolonged eczema, together with sports participation, further promotes the symptoms. The mechanisms of these novel findings warrant further investigation. © 2015 John Wiley & Sons A/S.

The aim of this study was to determine whether gait cycle characteristics are associated with running economy in elite Kenyan runners. Fifteen elite Kenyan male runners completed two constant-speed running sets on a treadmill (12 km ·h -1 and 20 km ·h -1 ). VO 2 and respiratory exchange ratio values were measured to calculate steady-state oxygen and energy cost of running. Gait cycle characteristics and ground contact forces were measured at each speed. Oxygen cost of running at different velocities was 192.2 ± 14.7 ml· kg -1 · km -1 at 12 km· h -1 and 184.8 ± 9.9 ml· kg -1 · km -1 at 20 km· h -1 , which corresponded to a caloric cost of running of 0.94 ± 0.07 kcal ·kg -1 ·km -1 and 0.93 ± 0.07 kcal· kg -1 · km -1 . We found no significant correlations between oxygen and energy cost of running and biomechanical variables and ground reaction forces at either 12 or 20 km· h -1 . However, ground contact times were ~10.0% shorter (very large effect) than in previously published literature in elite runners at similar speeds, alongside an 8.9% lower oxygen cost (very large effect). These results provide evidence to hypothesise that the short ground contact times may contribute to the exceptional running economy of Kenyan runners.

The aim of this study was to evaluate the association between overweight/obesity and the occurrence of traumatic dental injury among schoolchildren aged 7 to 14 years. A cross-sectional study was carried out involving 590 students at public schools in the city of Campina Grande, Brazil. The classification proposed by O'Brien (1994) was used for the diagnosis of traumatic dental injury. Overweight/obesity was determined based on the body mass index. Clinical examinations were performed by two examiners who had undergone a calibration exercise (Kappa statistics of 0.87 and 0.90 for intra-examiner and inter-examiner, respectively). Data analysis involved the chi-square test and Fisher's exact test with a 5% level of significance. Traumatic dental injury was less prevalent among the schoolchildren with overweight/obesity than those without this condition (8.7% and 13.3%, respectively). When the sample was stratified by gender and age, traumatic dental injury was also more prevalent among schoolchildren without overweight/obesity. When the sample was stratified based on ethnicity, prevalence rates were similar between those with and without overweight/obesity. In the overall sample, no significant association was found between overweight/obesity and traumatic dental injury (p = 0.253). Overweight/obesity among schoolchildren aged 7 to 14 years was not associated with traumatic dental injury in this study. The analysis of physical activity may be important to gain a better understanding of this finding.

Soil-transmitted helminth (STH) infection has been associated with lower cognitive performance of schoolchildren. To identify pathways through which STH infection might affect school performance, baseline data from a large rice-fortification trial in Cambodian schoolchildren were used to investigate associations between STH infection, micronutrient status, anemia, and cognitive performance. Complete data on anthropometry, cognitive performance, and micronutrient status were available for 1,760 schoolchildren, 6-16 years of age. STH infection was identified using Kato-Katz, whereas cognitive performance was assessed using Raven's Colored Progressive Matrices (RCPM), block design, and picture completion. STH infection was found in 18% of the children; almost exclusively hookwork infection. After adjusting for age and gender, raw cognitive test scores were significantly lower in hookworm-infected children (-0.65; -0.78; -2.03 points for picture completion, RCPM, and block design, respectively; P < 0.05 for all). Hookworm infection was associated with iron status (total body iron), but not with vitamin A and zinc status, nor with inflammation or anthropometry. Body iron was negatively associated with increased intensity of hookworm infection (R = 0.22, P < 0.001). Hookworm infection in Cambodian schoolchildren was associated with lower cognitive performance, an effect most likely mediated through lower body iron. Interventions that are more effective against hookworm infection are needed to contribute to better health and improvement of cognitive performance. © The American Society of Tropical Medicine and Hygiene.

OBJECTIVE: Because pulmonary embolism (PE) and COPD exacerbation have similar presentations and symptoms, PE can be overlooked in COPD patients. Our objective was to determine the prevalence of PE during COPD exacerbation and to describe the clinical aspects in COPD patients diagnosed with PE. METHODS: This was a prospective study conducted at a university hospital in the city of Ankara, Turkey. We included all COPD patients who were hospitalized due to acute exacerbation of COPD between May of 2011 and May of 2013. All patients underwent clinical risk assessment, arterial blood gas analysis, chest CT angiography, and Doppler ultrasonography of the lower extremities. In addition, we measured D-dimer levels and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels. RESULTS: We included 172 patients with COPD. The prevalence of PE was 29.1%. The patients with pleuritic chest pain, lower limb asymmetry, and high NT-pro-BNP levels were more likely to develop PE, as were those who were obese or immobile. Obesity and lower limb asymmetry were independent predictors of PE during COPD exacerbation (OR = 4.97; 95% CI, 1.775-13.931 and OR = 2.329; 95% CI, 1.127-7.105, respectively). CONCLUSIONS: The prevalence of PE in patients with COPD exacerbation was higher than expected. The association between PE and COPD exacerbation should be considered, especially in patients who are immobile or obese. PMID:24626268

Nutritional status was measured via anthropometry using BMI and tooth wear was measured using the Dental Wear Index; both these assessments were carried out by a trained recorder according to standard criteria. A modified version of the Child Oral Impacts on Daily Performances was used to assess quality of life. City of Bauru, in Brazil. A cluster sample of 396 schoolchildren (194 boys and 202 girls) aged 7-10 years. The anthropometric assessment showed similar situations for both sexes regarding underweight (31·40 % in boys and 30·20 % in girls) and overweight/obesity (33·96 % in boys and 33·17 % in girls). The underweight children showed a greater severity of tooth wear in the primary teeth (OR=0·72; CI 0·36, 1·42), although in the permanent dentition the obese children had a greater severity of tooth wear (OR=1·42; 95 % CI 0·31, 6·55). The tooth wear was correlated with age for both dentitions. Tooth wear in the primary and permanent dentition may be related to nutritional status. Tooth wear and obesity did not have a significant impact on the schoolchildren's perception of quality of life.

Studies mainly performed in adults have shown an association between the amount of sleep and obesity. To determine if there is an association between nocturnal sleep deprivation during the week and the weekend, eating habits, physical activity and nutritional status among Chilean schoolchildren. Crosssectional study. An anthropometric assessment was done among 6-11 year-old students; the Pittsburgh Sleep Quality Index (PSQI) was used among parents to measure their children's quality of sleep; they were asked about eating habits and physical activity. One thousand eight hundred and ten schoolchildren of both sexes, attending public schools in Santiago, were assessed. Out of these schoolchildren, 49.9% slept fewer hours per night than recommended. An association in the crude model (crude OR 1.82; CI 95%: 1.29-2.56), in model 2 adjusted for cola drinks (OR 1.83; CI 95%: 1.30-2.59) and in model 3 adjusted for dinner, cola drink and caffeine beverage consumption and nocturia (OR 1.85; CI 95%: 1.30-2.62) was observed. It was also noticed that exercising was a protective factor against overweight and obesity; however, periodic limb movement during sleep was a risk factor. This study showed an association between fewer hours of sleep and an increase in the risk of overweight/obesity. Sociedad Argentina de Pediatría.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6-7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively. A FFQ was used to determine the consumption of I-rich foods. A total of 1981 schoolchildren (52 % male) were included. The median UI was 173 μg/l, and 17·9 % of children showed UI<100 μg/l. The median UI was higher in males (180·8 v. 153·6 μg/l; P<0·001). Iodised salt (IS) intake at home was 69·8 %. IS consumption and intakes of ≥2 glasses of milk or 1 cup of yogurt/d were associated with significantly higher median UI. Median TSH was 0·90 mU/l and was higher in females (0·98 v. 0·83; P<0·001). In total, 0·5 % of children had known hypothyroidism (derived from the questionnaire) and 7·6 % had TSH levels above reference values. Median TSH was higher in schoolchildren with family history of hypothyroidism. I intake was adequate in Spanish schoolchildren. However, no correlation was found between TSH and median UI in any geographical area. The prevalence of TSH above reference values was high and its association with thyroid autoimmunity should be determined. Further assessment of thyroid autoimmunity in Spanish schoolchildren is desirable.

Background The objective of this study was to compare the socioeconomic and family characteristics of underprivileged schoolchildren with and without curative dental needs participating in a dental health program. Methods A random sample of 1411 of 8-to-10 year-old Brazilian schoolchildren was examined and two sample groups were included in the cross-sectional study: 544 presented curative dental needs and the other 867 schoolchildren were without curative dental needs. The schoolchildren were examined for the presence of caries lesions using the DMFT index and their parents were asked to answer questions about socioenvironmental characteristics of their families. Logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels. Results After adjusting for potential confounders, it was found that families earning more than one Brazilian minimum wage, having fewer than four residents in the house, families living in homes owned by them, and children living with both biological parents were protective factors for the presence of dental caries, and consequently, curative dental needs. Conclusions Socioeconomic status and family structure influences the curative dental needs of children from underprivileged communities. In this sense, dental health programs should plan and implement strategic efforts to reduce inequities in oral health status and access to oral health services of vulnerable schoolchildren and their families.

A cross-sectional study involving 408 schoolchildren was performed from November 2013 to February 2014 to assess the prevalence of intestinal helminthic infections and malnutrition among schoolchildren of the Zegie Peninsula, northwestern Ethiopia. A structured questionnaire was used to gather data on the demographic and risk factors associated with intestinal helminthic infections. Stool samples were collected and examined for helminth eggs using the formalin-ether concentration technique. In addition, anthropometric measurements were performed to assess the nutritional status of the schoolchildren. The overall prevalence of intestinal helminthic infections in the study area was 69.1%. Single, double, triple, and quadruple infections were 42.2%, 18.4%, 5.9%, and 0.7%, respectively. The prevalence of hookworm, Schistosoma mansoni, Ascaris lumbricoides, Trichuris trichiura, Hymenolepis nana, and Strongyloides stercoralis infections were 43.4%, 29.9%, 12.7%, 10%, 4.6%, and 0.7%, respectively. The prevalence of malnutrition in terms of stunting, being underweight, and wasting were 15.3%, 18%, and 27.6%, respectively. However, no significant association was found between intestinal helminthic infections and stunting, being underweight and wasting (p>0.05). It can be concluded that intestinal helminthic infections, specifically infections due to hookworm and S. mansoni, are important health problems among schoolchildren of the Zegie Peninsula.

To investigate the changes in caries experience and prevalence among schoolchildren of the canton of Basel-Landschaft, Switzerland, over the course of 20 years. A random sample of either schoolchildren aged 7, 12, and 15 years (in 1992) or aged 12 and 15 years (in 1997) or their respective school classes (2001, 2006 and 2011) was selected so that approximately 10% of schoolchildren could be examined. The children's dmft and DMFT scores were determined according to the WHO methodology and analyzed using cluster-adjusted ordinary multiple linear regression modeling. For all age groups, the respective dmft/DMFT values decreased steadily from 1992 to 2006 but increased again in 2011. However, the observed differences were not statistically significant over the examination years from 2001 to 2011. Schoolchildren with a migrant background had approximately two- to threefold higher dmft/DMFT values. In the years from 1992 to 2001, a steady decline in caries was observed in all age groups of schoolchildren examined in the canton of Basel-Landschaft. However, in the subsequent 10 years, this decline has leveled off. The mean dmft/DMFT values are comparable to those in other parts of Switzerland. Migrants are a caries-risk group; the mean dmft/DMFT values were higher in schoolchildren with a migrant background than in the comparable Swiss children. © 2015 John Wiley & Sons A/S.

Tinea capitis is endemic among schoolchildren in tropical Africa. The objective was to determine the prevalence of symptomatic tinea capitis in schoolchildren in Gabon. A cross-sectional study was conducted with 454 children aged 4-17 years, attending a rural school and an urban school. The diagnosis of tinea capitis was based on clinically manifest infection, direct microscopic examination using 20% potassium hydroxide (KOH) solution and fungal culture. Based on clinical examination, 105 (23.1%) of 454 children had tinea capitis. Seventy-four (16.3%) children were positive by direct examination (KOH) and/or fungal culture. The prevalence of tinea capitis depended on the school studied and ranged from 20.4% in the urban school with a higher socioeconomic status to 26.3% in the rural school with a lower socioeconomic status. Similarly, the spectrum of causative species varied between the different schools. Taken the schools together, Trichophyton soudanense (29.4%) was the most prominent species, followed by Trichophyton tonsurans (27.9%) and Microsporum audouinii (25.0%). Clinically manifest tinea capitis is endemic among schoolchildren in the Lambaréné region in Gabon. The prevalence of tinea capitis and the causative species depended on the type of school that was investigated. © 2010 Blackwell Verlag GmbH.

To compare the effectiveness of water and salt community-based fluoridation methods on caries experience among schoolchildren. Data derived from two population-based oral health surveys of 12-year-old schoolchildren exposed to different community-based fluoridation methods were compared: artificially fluoridated water in Porto Alegre, South Brazil and artificially fluoridated salt in Montevideo, Uruguay. Data on socio-demographic characteristics, maternal education and oral hygiene were collected. Dental caries was defined according to the WHO criteria (cavitated lesions) and to the modified WHO criteria (active noncavitated lesions and cavitated ones). The association between community-based fluoridation methods and dental caries was modelled using logistic (caries prevalence) and Poisson regression (DMFT). Odds ratios (OR), rate ratios (RR), and the 95% confidence intervals (CI) were estimated. A total of 1528 in Porto Alegre and 1154 in Montevideo were examined (response rates: 83.2% and 69.6%, respectively). Adjusted estimates for caries prevalence and DMFT showed that schoolchildren from Porto Alegre were less affected by dental caries than their counterparts from Montevideo, irrespective of the criteria used. After adjusting for important characteristics, schoolchildren exposed to fluoridated salt had significantly higher likelihood of having caries (WHO criteria) than those exposed to fluoridated water (OR for prevalence=1.61, 95% CI=1.26-2.07; RR for DMFT=1.32, 95% CI=1.16-1.51). Similar differences were observed using the modified WHO criteria. Fluoridated water appears to provide a better protective effect against dental caries than fluoridated household salt among schoolchildren from developing countries. © 2016 John Wiley & Sons A/S.

Chronic musculoskeletal pain (MSP) is common in children and can be due to several non-inflammatory conditions such as the benign joint hypermobility syndrome (BJHS), and growing pains (GP). We evaluated frequency, risk factors and causes of MSP in a large cohort of healthy schoolchildren. We conducted a cross sectional study in a cohort of healthy schoolchildren, aged 8-13 years, by collecting information and performing a physical examination. The anamnesis was focused on family history for MSP, presence and sites of MSP interfering with the regular daily activities during the previous 6 months and presence of GP. Physical examination included body mass index, pubertal stage and musculoskeletal examination focused on the presence of hypermobility according to the Beighton criteria. Two hundred and eighty-nine schoolchildren, 143 females and 146 males, participated in the study. Chronic MSP occurred in 30.4% of subjects, BJHS occurred in 13.2%. GJH was more frequent in symptomatic subjects than in asymptomatic ones (p=0.054). Symptomatic subjects were more frequently pre-pubertal than pubertal (p=0.006). In general, GP, BJHS and obesity (OB) were mutually exclusive as causes of MSP as, among 88 symptomatic subjects, 52.3% had GP, 40.9% presented BJHS, 4.5% were OB and only two (2.3%) presented both BJHS and OB. After puberty, GP persisted in 66.7%, BJHS in 26.7% and in association with OB in 6.7%. Approximately one third of schoolchildren suffer from MSP. BJHS, GP and OB are mutually exclusive as causes of MSP in schoolchildren. Pubertal stage plays an important role in the physiopathology of this condition.

To assess the epidemiology and risk indicators for dental erosion among 12-year-old schoolchildren in South Brazil. A population-based cross-sectional survey was conducted in Porto Alegre, Brazil, using a representative sample of 12-year-old schoolchildren (n = 1,528). Dental erosion was recorded according to the Basic Erosive Wear Examination (BEWE) index. Parents answered questions on socio-economic status, brushing frequency and general health. Schoolchildren answered questions on dietary habits. Anthropometric data were collected. Statistical analysis included logistic and Poisson regression models. The prevalence of dental erosion was 15% [95% confidence interval (95% CI): 13.6-16.5], being mainly mild erosion. Boys [odds ratio (OR) = 1.57, 95% CI: 1.17-2.10], private school attendees (OR = 1.45, 95% CI: 1.01-2.06) and schoolchildren reporting the daily consumption of soft drinks (OR = 5.04, 95% CI: 1.17-21.71) were more likely to have at least one tooth with dental erosion. Gender [boys, rate ratio (RR) = 1.66, 95% CI: 1.28-2.17], type of school (private, RR = 1.89, 95% CI: 1.53-2.35), the consumption of soft drinks (sometimes: RR = 5.27, 95% CI: 1.46-19.05; daily: RR = 6.82, 95% CI: 1.39-33.50) and the daily consumption of lemon (RR = 1.49, 95% CI: 1.11-2.00) were significantly associated with the number of affected surfaces. The present study found a moderate prevalence of dental erosion among young schoolchildren, with mild erosion being the most prevalent condition. Socio demographic variables and dietary habits were associated with dental erosion in this population. © 2015 FDI World Dental Federation.

Women living on rural Kenyan dairy farms spend significant amounts of time collecting wood for cooking. Biogas digesters, which generate biogas for cooking from the anaerobic decomposition of livestock manure, are an alternative fuel source. The objective of this study was to quantify the quality of life and health benefits of installing biogas digesters on rural Kenyan dairy farms with respect to wood utilisation. Women from 62 farms (31 biogas farms and 31 referent farms) participated in interviews to determine reliance on wood and the impact of biogas digesters on this reliance. Self-reported back pain, time spent collecting wood and money spent on wood were significantly lower (p < 0.01) for the biogas group, compared to referent farms. Multivariable linear regression showed that wood consumption increased by 2 lbs/day for each additional family member living on a farm. For an average family of three people, the addition of one cow was associated with increased wood consumption by 1.0 lb/day on biogas farms but by 4.4 lbs/day on referent farms (significant interaction variable - likely due to additional hot water for cleaning milk collection equipment). Biogas digesters represent a potentially important technology that can reduce reliance on wood fuel and improve health for Kenyan dairy farmers.
Sanitation behavior among schoolchildren in a multi-ethnic area of Northern rural Vietnam
2012-01-01
Background In Vietnam, efforts are underway to improve latrine use in rural and remote areas with particular focus on increasing coverage of sanitation in schools. However, there is a lack of information on how the school program affects latrine use by schoolchildren and at community level. This paper analyzes sanitation use among schoolchildren in a multi-ethnic area to inform future school-based sanitation promotion programmes. Methods A combination of quantitative and qualitative methods was applied during a 5 months period in six primary and secondary schools and in the homes of schoolchildren in four different ethnic villages in Northern rural Vietnam. Using a structured questionnaire, 319 children were interviewed face-to-face to collect quantitative data. Qualitative methods included extensive observations at schools and in the homes of 20 children, a single day's diary writings of 234 children, in-depth interviews with children (20), their parents (20) and school staff (10), and focus group discussions with parents (4) and teachers (6), and picture drawing with children (12). Results All surveyed schools had student latrines. However, the observed schoolchildren most commonly urinated and defecated in the open. Main barriers for latrine use included inadequate number of latrines, limited accessibility to latrines, lack of constant water supply in latrines and lack of latrine maintenance by school management. Programs promoting latrine use for children were not conducted in either schools or communities and were not established as a preferred social norm in such settings. Children perceived existing school latrines as unappealing and expressed a wish to have basic, functional, clean, and colorful school latrines with privacy. Conclusions The paper shows that the current school based sanitation promotion is insufficient to change sanitation behavior of school children irrespective of their ethnicity. It is important that schools, households and communities

BACKGROUND: COPD is a major cause of morbidity and mortality in the United States as well as throughout the rest of the world. An exacerbation of COPD (periodic escalations of symptoms of cough, dyspnea, and sputum production) is a major contributor to worsening lung function, impairment in quality of life, need for urgent care or hospitalization, and cost of care in COPD. Research conducted over the past decade has contributed much to our current understanding of the pathogenesis and treatment of COPD. Additionally, an evolving literature has accumulated about the prevention of acute exacerbations. METHODS: In recognition of the importance of preventing exacerbations in patients with COPD, the American College of Chest Physicians (CHEST) and Canadian Thoracic Society (CTS) joint evidence-based guideline (AECOPD Guideline) was developed to provide a practical, clinically useful document to describe the current state of knowledge regarding the prevention of acute exacerbations according to major categories of prevention therapies. Three key clinical questions developed using the PICO (population, intervention, comparator, and outcome) format addressed the prevention of acute exacerbations of COPD: nonpharmacologic therapies, inhaled therapies, and oral therapies. We used recognized document evaluation tools to assess and choose the most appropriate studies and to extract meaningful data and grade the level of evidence to support the recommendations in each PICO question in a balanced and unbiased fashion. RESULTS: The AECOPD Guideline is unique not only for its topic, the prevention of acute exacerbations of COPD, but also for the first-in-kind partnership between two of the largest thoracic societies in North America. The CHEST Guidelines Oversight Committee in partnership with the CTS COPD Clinical Assembly launched this project with the objective that a systematic review and critical evaluation of the published literature by clinical experts and researchers in

To estimate the prevalence of overweight and obesity in schoolchildren in rural areas. A cross-sectional study was carried out in a sample of 1,513 schoolchildren aged 6, 11 and 14 years. Data were collected on height and weight with digital scales equipped with a measuring rod. We used three criteria to define overweight and obesity: Cole's points, the Centers for Disease Control and Prevention (CDC) criteria and Hernandez's tables. When Cole's points were used, 24.6% (95%CI: 22.5 - 26.8) were overweight and 11.6% (95%CI: 10-13.3) were obese; these percentages were higher in children aged 11 and 6 years, respectively. According CDC growth charts, 19.8% of children (95%CI: 17.9-21.9) were overweight and 16.5% (95%CI: 14.7-18.4) were obese, corresponding to higher percentages at 14 and 6 years. When Hernandez's tables were used, 11.5% (95%CI: 10-13.2) were overweight and 18.6% (95%CI: 16.7-20.6) were obese, and both disorders were higher in children aged 11 years. The risk of obesity and overweight was higher in small rural areas (<5,000 people), with OR = 1.49 (95%CI: 1.13-1.95) and OR = 1.33 (95%CI: 1.06-1.67), respectively. The prevalence of overweight and obesity in schoolchildren in rural areas is very high and is even higher in towns with less than 5,000 inhabitants. Copyright © 2011 SESPAS.

To develop and validate a predictive model for first severe chronic obstructive pulmonary disease (COPD) exacerbation using health insurance claims data and to validate the risk measure of controller medication to total COPD treatment (controller and rescue) ratio (CTR). A predictive model was developed and validated in 2 managed care databases: Truven Health MarketScan database and Reliant Medical Group database. This secondary analysis assessed risk factors, including CTR, during the baseline period (Year 1) to predict risk of severe exacerbation in the at-risk period (Year 2). Patients with COPD who were 40 years or older and who had at least 1 COPD medication dispensed during the year following COPD diagnosis were included. Subjects with severe exacerbations in the baseline year were excluded. Risk factors in the baseline period were included as potential predictors in multivariate analysis. Performance was evaluated using C-statistics. The analysis included 223,824 patients. The greatest risk factors for first severe exacerbation were advanced age, chronic oxygen therapy usage, COPD diagnosis type, dispensing of 4 or more canisters of rescue medication, and having 2 or more moderate exacerbations. A CTR of 0.3 or greater was associated with a 14% lower risk of severe exacerbation. The model performed well with C-statistics, ranging from 0.711 to 0.714. This claims-based risk model can predict the likelihood of first severe COPD exacerbation. The CTR could also potentially be used to target populations at greatest risk for severe exacerbations. This could be relevant for providers and payers in approaches to prevent severe exacerbations and reduce costs.

Background: A history of past exacerbations is a predictor of future events for patients with chronic obstructive pulmonary disease (COPD). Very little is known about the effect of pharmacologic therapies on patients with frequent or infrequent exacerbations. Methods: We conducted a post-hoc analysis of the Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT®)trial database. Patients were classified as having a low risk of exacerbations if they experienced ≤1 exacerbation and no COPD-related hospitalization(s) in the year preceding trial entry or as high risk of exacerbations if they had ≥2 exacerbations (courses of oral steroids/antibiotics) or ≥1 COPD-related hospitalization(s) in the year preceding the trial. Results: In patients at low risk or high risk for exacerbations, compared to placebo, tiotropium significantly reduced: 1) the time to first COPD exacerbation (hazard ratio [HR]: 0.81; 95% confidence interval [CI]: 0.74, 0.88; p <0.0001; HR: 0.89; 95% CI: 0.81, 0.97; p=0.0066, respectively); 2) the number of COPD exacerbations (rate ratio [RR]: 0.79; 95% CI: 0.72, 0.86; p<0.0001; RR: 0.88; 95% CI: 0.81; 0.95; p=0.0009). Furthermore, upon treatment with tiotropium, the proportion of patients transitioning from the low- to the high-risk exacerbations group was statistically lower compared to placebo (RR: 0.78; 95% CI: 0.67, 0.92; p=0.0030) Conclusions: This analysis shows that tiotropium reduces the risk of subsequent exacerbation and also prolongs time to first exacerbation, in both the high- and low-risk exacerbator subgroups. It also decreases the proportion of patients who shift from the low- to the high-risk exacerbations group compared to placebo. PMID:28848836

The objectives of this study was to conduct a survey on schistosomiasis and soil-transmitted helminth (STH) infections in order to come up with feasible control strategies in Lake Victoria basin, Tanzania. Depending on the size of the school, 150-200 schoolchildren were recruited for the study. Duplicate Kato-Katz stool smears were prepared from each child and microscopically examined for Schistosoma mansoni and STHs. Urine specimens were examined for Schistosoma haematobium eggs using the filtration technique. After the survey, mass drug administration was done using praziquantel and albendazole for schistosomiasis and STHs infections, respectively. A total of 5,952 schoolchildren from 36 schools were recruited for the study and had their stool and urine specimens examined. Out of 5,952 schoolchildren, 898 (15.1%) were positive for S. mansoni, 754 (12.6%) for hookworms, 188 (3.2%) for Ascaris lumblicoides, and 5 (0.008%) for Trichuris trichiura. Out of 5,826 schoolchildren who provided urine samples, 519 (8.9%) were positive for S. haematobium eggs. The results revealed that intestinal schistosomiasis, urogenital schistosomiasis, and STH infections are highly prevalent throughought the lake basin. The high prevalence of intestinal and urogenital schistosomisiasis in the study area was a function of the distance from Lake Victoria, the former being more prevalent at localities close to the lake, whilst the latter is more so away from it. Control of schistosomiasis and STHs in the study area requires an integrated strategy that involves provision of health education to communities, regular treatments, and provision of adequate safe water supply and sanitation facilities.

Central auditory processing screening in schoolchildren has led to debates in literature, both regarding the protocol to be used and the importance of actions aimed at prevention and promotion of auditory health. Defining effective screening procedures for central auditory processing is a challenge in Audiology. This study aimed to analyze the scientific research on central auditory processing screening and discuss the effectiveness of the procedures utilized. A search was performed in the SciELO and PUBMed databases by two researchers. The descriptors used in Portuguese and English were: auditory processing, screening, hearing, auditory perception, children, auditory tests and their respective terms in Portuguese. original articles involving schoolchildren, auditory screening of central auditory skills and articles in Portuguese or English. studies with adult and/or neonatal populations, peripheral auditory screening only, and duplicate articles. After applying the described criteria, 11 articles were included. At the international level, central auditory processing screening methods used were: screening test for auditory processing disorder and its revised version, screening test for auditory processing, scale of auditory behaviors, children's auditory performance scale and Feather Squadron. In the Brazilian scenario, the procedures used were the simplified auditory processing assessment and Zaidan's battery of tests. At the international level, the screening test for auditory processing and Feather Squadron batteries stand out as the most comprehensive evaluation of hearing skills. At the national level, there is a paucity of studies that use methods evaluating more than four skills, and are normalized by age group. The use of simplified auditory processing assessment and questionnaires can be complementary in the search for an easy access and low-cost alternative in the auditory screening of Brazilian schoolchildren. Interactive tools should be proposed, that

To associate the nutritional status of elementary schoolchildren with their gender, age group, and economic status based on a cross-sectional study carried out at public schools in the municipality of Cruzeiro do Oeste, Southern Brazil. The study was performed in 2010 including 939 schoolchildren aged six to ten years-old. The economical status of the families was classified based on a socioeconomic ranking questionnaire (Brazilian Association of Survey Companies), and the body mass index was calculated. Data were analyzed by descriptive statistics, and differences between independent groups were verified by Mann-Whitney and Kruskal-Wallis tests, while possible associations were verified by the chi-square test, being significant p<0.05. The prevalence of obesity in the sample was 8.0%, and overweight, 16.4%. No association was found between the socioeconomic and nutritional status or between the nutritional status and gender. A high prevalence of overweight and obesity was found in this study, indicating that children of both genders are affected regardless of their economical status and age.

Identify disparities by race/ethnicity and obesity status in the consumption of sugar-sweetened beverages (SSBs) and other beverages among United States schoolchildren to help tailor interventions to reduce childhood obesity. Secondary data analysis using beverage intake data from 24-hour dietary recalls and measured height and weight from the third School Nutrition Dietary Assessment Study, a 2004-2005 nationally representative sample of school-aged children and schools. Schools participating in the National School Lunch Program (n = 287). Children in grades 1-12 with a completed 24-hour dietary recall (n = 2,314). Percentage of children consuming beverages in 8 beverage categories by school level and consumption location. Two-tailed t tests to determine significant differences (P < .05) between the proportions of children consuming beverages by race/ethnicity and weight status. Beverage consumption patterns did not substantially differ across weight status groups, but they differed by race/ethnicity in the home. Non-Hispanic black elementary schoolchildren consumed nonsoda SSBs more often and unflavored, low-fat milk less often at home than non-Hispanic white schoolchildren. Higher consumption of SSBs coupled with a lower consumption of milk is disproportionately affecting non-Hispanic black schoolchildren. Targeted interventions by racial/ethnic group are needed to promote more healthful beverage choices among schoolchildren, particularly at home.

This study sought to adapt a battery of Western speech and language assessment tools to a rural Kenyan setting. The tool was developed for children whose first language was KiGiryama, a Bantu language. A total of 539 Kenyan children (males=271, females=268, ethnicity=100% Kigiryama. Data were collected from 303 children admitted to hospital with severe malaria and 206 age-matched children recruited from the village communities. The language assessments were based upon the Content, Form and Use (C/F/U) model. The assessment was based upon the adapted versions of the Peabody Picture Vocabulary Test, Test for the Reception of Grammar, Renfrew Action Picture Test, Pragmatics Profile of Everyday Communication Skills in Children, Test of Word Finding and language specific tests of lexical semantics, higher level language. Preliminary measures of construct validity suggested that the theoretical assumptions behind the construction of the assessments were appropriate and re-test and inter-rater reliability scores were acceptable. These findings illustrate the potential to adapt Western speech and language assessments in other languages and settings, particularly those in which there is a paucity of standardised tools.

Exacerbations of chronic obstructive pulmonary disease (COPD) carry significant consequences for patients and are responsible for considerable health-care costs-particularly if hospitalization is required. Despite the importance of hospitalized exacerbations, relatively little is known about their determinants. This study aimed to analyze predictors of hospitalized exacerbations and mortality in COPD patients. This was a retrospective population-based cohort study. We selected 900 patients with confirmed COPD aged ≥35 years by simple random sampling among all COPD patients in Cantabria (northern Spain) on December 31, 2011. We defined moderate exacerbations as events that led a care provider to prescribe antibiotics or corticosteroids and severe exacerbations as exacerbations requiring hospital admission. We observed exacerbation frequency over the previous year (2011) and following year (2012). We categorized patients according to COPD severity based on forced expiratory volume in 1 second (Global Initiative for Chronic Obstructive Lung Disease [GOLD] grades 1-4). We estimated the odds ratios (ORs) by logistic regression, adjusting for age, sex, smoking status, COPD severity, and frequent exacerbator phenotype the previous year. Of the patients, 16.4% had ≥1 severe exacerbations, varying from 9.3% in mild GOLD grade 1 to 44% in very severe COPD patients. A history of at least two prior severe exacerbations was positively associated with new severe exacerbations (adjusted OR, 6.73; 95% confidence interval [CI], 3.53-12.83) and mortality (adjusted OR, 7.63; 95%CI, 3.41-17.05). Older age and several comorbidities, such as heart failure and diabetes, were similarly associated. Hospitalized exacerbations occurred with all grades of airflow limitation. A history of severe exacerbations was associated with new hospitalized exacerbations and mortality.

Objectives To investigate factors influencing consumption of traditional foods (e.g. wild game, fish) and concerns about environmental contaminants among schoolchildren of the Mushkegowuk Territory First Nations (Moose Factory, Fort Albany, Kashechewan, Attawapiskat, and Peawanuck). Study design Cross-sectional data collection from a Web-based Eating Behaviour Questionnaire (WEB-Q). Methods Schoolchildren in grades 6–12 (n =262) responded to 4 of the WEB-Q questions: (a) Do you eat game? (b) How often do you eat game? (c) How concerned are you about the environmental contaminants in the wild game and fish that you eat? (d) I would eat more game if… [6 response options]. Data were collected in 2004 (Fort Albany), 2005 (Peawanuck), 2006 (Attawapiskat), 2007 (Moose Factory) and 2009 (Kashechewan). Hierarchical log-linear modelling (LLM) was used for analyses of multi-way frequency data. Results Of the schoolchildren answering the specific questions: 174 consumed game; 95 reported concerns about contaminants in game; and 84 would increase their game consumption if it were more available in their homes. LLM revealed significant differences between communities; schoolchildren in Moose Factory consumed game “rarely or never” at greater than expected frequency, and fewer than expected consumed game “at least once a day”. Schoolchildren in Kashechewan had greater frequency of daily game consumption and few were concerned about contaminants in game. Using LLM, we found that sex was an insignificant variable and did not affect game consumption frequency or environmental contaminant concern. Conclusion The consumption of traditional foods differed between communities and appears to be related to contamination concerns. In addition, latitudinal variation appears to influence the frequency of traditional food consumption in children; children in the most southerly location consumed traditional food less frequently.

To determine the prevalence of refractive errors, among 6- to 15-year-old schoolchildren in the city of Dezful in western Iran. In this cross-sectional study, 1375 Dezful schoolchildren were selected through multistage cluster sampling. After obtaining written consent, participants had uncorrected and corrected visual acuity tests and cycloplegic refraction at the school site. Refractive errors were defined as myopia [spherical equivalent (SE) -0.5 diopter (D)], hyperopia (SE ≥ 2.0D), and astigmatism (cylinder error > 0.5D). 1151 (83.7%) schoolchildren participated in the study. Of these, 1130 completed their examinations. 21 individuals were excluded because of poor cooperation and contraindication for cycloplegic refraction. Prevalence of myopia, hyperopia, and astigmatism were 14.9% (95% confidence interval (CI): 10.1-19.6), 12.9% (95% CI: 7.2-18.6), and 45.3% (95% CI: 40.3-50.3), respectively. Multiple logistic regression analysis showed an age-related increase in myopia prevalence (p < 0.001) and a decrease in hyperopia prevalence (p < 0.001). There was a higher prevalence of myopia in boys (p<0.001) and hyperopia in girls (p = 0.007). This study showed a considerably high prevalence of refractive errors among the Iranian population of schoolchildren in Dezful in the west of Iran. The prevalence of myopia is considerably high compared to previous studies in Iran and increases with age.

We evaluated associations between use of public places for physical activity and active leisure (PAAL) and their distances from subjects' homes and indicators of overweight and obesity, among schoolchildren from different socioeconomic levels, in the city of Florianópolis, Brazil. Cross-sectional study conducted on a sample of 2,152 schoolchildren aged 7 to 14 years, enrolled at 30 public and private schools. The exposure variables were the use of public places for PAAL in the neighborhood and their distance from schoolchildren's homes. The outcomes were body mass index (BMI) and waist circumference (WC). Univariate and multivariate linear regression analyses were conducted according to income strata. Among the schoolchildren from low-income families, living closer to parks/playgrounds was associated with lower BMI (β = -2.15; 95% confidence interval, CI = -2.53; -1.77) and lower WC (β = -0.11 95% CI = -0.17; -0.05), while living at these distances from football pitches was associated with higher BMI (β = 1.73; 95% CI = 0.31; 3.15) and larger WC measurements (β = 0.03; 95% CI = 0.005; 0.14). Among the schoolchildren in low-income groups, living at an intermediate distance from beaches was associated with lower BMI (β = -1.10; 95% CI = -1.61; -0.59). Living closer to parks/playgrounds was associated with lower BMI and WC among schoolchildren from low-income families. Living closer to football pitches was associated with higher BMI and WC among these schoolchildren. Living at intermediate distances from beaches was associated with lower BMI among these schoolchildren.

To investigate the prevalence of dental caries and treatment needs in schoolchildren aged 7-14 years from Zagreb. Dental examinations based on the World Health Organization criteria were performed on 1168 children in the period 2009-2010. The teeth were clinically examined with standard dental instruments using visual-tactile method under standard dental light. We recorded the clinical indexes of decayed, missed, and filled teeth (DMFT and dmft; upper-case letters refer to permanent and lower-case letters to primary teeth) and decayed, missed, and filled surfaces (DMFS), as well as the significant caries index (SiC). The median DMFT and DMFS of all children were 3 and 4, respectively. The median DMFT and DMFS of 12-year-old children were 4 and 5, respectively. The highest median DMFT score of 7 was found among 14-year-old children. There was a significant difference between age groups (7-10 years and 11-14 years) in DMFT and DMFS. Among 8-year-old children, the median dmft index was the highest (5.5) and SiC index was 7.4. As far as the location of caries on the surface of the first permanent molar is concerned, caries occurred mostly in the central occlusal surface (27.6%). Our results showed a high caries prevalence among schoolchildren in Zagreb, indicating a need for an extensive program of primary oral health care.

The exacerbation of asthma by workplace conditions is common, but little is known about which agents pose a risk. We used data from an existing survey of adults with asthma to identify occupational exposures associated with severe exacerbation of asthma. Questionnaires were completed by 557 working adults with asthma. Severe exacerbation of asthma in the past 12 months was defined as asthma-related hospitalization, or reports of both unplanned asthma care and treatment with a short course of oral corticosteroids. Occupational exposures for the same time period were assessed using an asthma-specific job exposure matrix. We modeled severe exacerbation to yield prevalence ratios (PRs) for exposures while controlling for potential confounders. A total of 164 participants (29%) were positive for severe exacerbation, and 227 (40.8%) were assessed as being exposed to asthma agents at work. Elevated PRs were observed for several specific agents, notably the irritant subcategories of environmental tobacco smoke (PR 1.84, 95%CI 1.34-2.51) among all participants, inorganic dusts (PR 2.53, 95%CI 1.37-4.67) among men, and the low molecular weight subcategory of other highly reactive agents (PR 1.97, 95%CI 1.08-3.60) among women. Among working adults with asthma, severe exacerbation was associated with several occupational agents.
Sternal foramina and variant xiphoid morphology in a Kenyan population.

Sternal foramina may pose a great hazard during sternal puncture, due to inadvertent cardiac or great vessel injury. They can also be misinterpreted as osteolytic lesions in cross-sectional imaging of the sternum. On the other hand, variant xiphoid morphology such as bifid, duplicated, or trifurcated may be mistaken for fractures during imaging. The distribution of these anomalies differs between populations, but data from Africans is scarcely reported. This study therefore aimed to investigate the distribution and frequency of sternal foramina and variant xiphoid morphology in a Kenyan population. Eighty formalin-fixed adult sterna (42 males [M], 38 females [F]) of age range 18-45 years were studied during dissection at the Department of Human Anatomy, University of Nairobi. Soft tissues were removed from the macerated sterna by blunt dissection and foramina recorded in the manubrium, body, and xiphoid process. The xiphisternal ending was classified as single, bifurcated (2 xiphoid processes with a common stem), or duplicated (2 xiphoid processes with separate stems). Results were analysed using SPSS version 17.0. Foramina were present in 11 specimens (13.8%): 7 M, 4 F. The highest frequency was in the sternal body (n = 9), where they predominantly occurred at the 5th intercostal segment. Xiphoid foramina were present in 2 specimens (both males) (2.5%), while manubrial foramen was not encountered. The xiphisternum ended as a single process in 64 cases (34 M, 30 F) (80%). It bifurcated in 10 cases (5 M, 5 F) (12.5%), and duplicated in 6 cases (4 M, 2 F) (7.5%). There were no cases of trifurcation. Sternal foramina in Kenyans vary in distribution and show higher frequency than in other populations. These variations may complicate sternal puncture, and due caution is recommended. The variant xiphisternal morphology may raise alarm for xiphoid fractures and may therefore be considered a differential.

Food allergy (FA) prevalence is well documented in developed countries and appears to be increasing, but remains unknown in most Latin American countries. We aimed to evaluate on a population basis the parent-reported prevalence of FA and its clinical characteristics in Mexican schoolchildren. A validated Spanish version of a structured written questionnaire was administered to parents of schoolchildren aged 5-13 years old from Culiacan, Mexico. A total of 1049 parents responded to the survey (response rate, 84%). The estimated prevalence rates (95% CI) were: adverse food reactions 10.0% (8.3-11.9), "perceived FA, ever" 5.5% (4.3-7.0), "physician-diagnosed FA, ever" 4.9% (3.7-6.3), "immediate-type FA, ever" 4.4% (3.3-5.8), "immediate-type FA, current" 3.5% (2.6-4.8), and anaphylaxis 1.2% (0.72-2.1). Immediate hypersensitivity reactions were mainly triggered by the consumption of shrimp (1.3%), other shellfish (0.7%), strawberry (0.6%), chocolate (0.5%), and egg (0.4%). Schoolchildren with "immediate-type FA, current" had more atopic dermatitis and allergic rhinitis (p<0.05), but not asthma or drug allergy (p>0.05) than children without FA. All cases of anaphylaxis sought medical attention, but only one child had physician-diagnosed anaphylaxis and was advised to acquire an epinephrine autoinjector. The prevalence of "immediate-type FA, current" to any food is 3.5% in Mexican schoolchildren. The poor recognition of anaphylaxis and the low frequency of prescription of epinephrine autoinjectors suggest that acute food-induced allergic reactions are not optimally managed in Mexico.

During most COPD exacerbations, patients continue to live in the community but there is little information on changes in activity during exacerbations due to the difficulties of obtaining recent, prospective baseline data. Patients recorded on daily diary cards any worsening in respiratory symptoms, peak expiratory flow (PEF) and the number of steps taken per day measured with a Yamax Digi-walker pedometer. Exacerbations were defined by increased respiratory symptoms and the number of exacerbations experienced in the 12 months preceding the recording of daily step count used to divide patients into frequent (> = 2/year) or infrequent exacerbators. The 73 COPD patients (88% male) had a mean (±SD) age 71(±8) years and FEV1 53(±16)% predicted. They recorded pedometer data on a median 198 days (IQR 134-353). At exacerbation onset, symptom count rose by 1.9(±1.3) and PEF fell by 7(±13) l/min. Mean daily step count fell from 4154(±2586) steps/day during a preceding baseline week to 3673(±2258) step/day during the initial 7 days of exacerbation (p = 0.045). Patients with larger falls in activity at exacerbation took longer to recover to stable level (rho = -0.56; p < 0.001). Recovery in daily step count was faster (median 3.5 days) than for exacerbation symptoms (median 11 days; p < 0.001). Recovery in step count was also faster in untreated compared to treated exacerbation (p = 0.030).Daily step count fell faster over time in the 40 frequent exacerbators, by 708 steps/year, compared to 338 steps/year in 33 infrequent exacerbators (p = 0.002). COPD exacerbations reduced physical activity and frequent exacerbations accelerate decline in activity over time.

The aim of this study was to assess the prevalence, extent, severity, intraoral distribution and risk indicators for erosive tooth wear (ETW) among 12-year-old schoolchildren from Montevideo, Uruguay. A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was detected in 4.4% of schoolchildren. The overall prevalence of ETW differed significantly between categories of gender and socioeconomic status, but only between gender in the severe ETW analysis. The overall extent of ETW was significantly different between categories of gender, socioeconomic status, and swish before swallow. The extent of severe ETW differed between categories of swish before swallow and brushing frequency. In the logistic regression analysis, no association was found between the studied variables and the overall prevalence of ETW. Males were more likely to have severe ETW than females (OR = 3.22, 95% CI = 1.50-6.89). ETW may be considered a public health problem among 12-year-old-Uruguayan schoolchildren.

Background Malnutrition is still highly prevalent in developing countries. Schoolchildren may also be at high nutritional risk, not only under-five children. However, their nutritional status is poorly documented, particularly in urban areas. The paucity of information hinders the development of relevant nutrition programs for schoolchildren. The aim of this study carried out in Ouagadougou was to assess the nutritional status of schoolchildren attending public and private schools. Methods The study was carried out to provide baseline data for the implementation and evaluation of the Nutrition Friendly School Initiative of WHO. Six intervention schools and six matched control schools were selected and a sample of 649 schoolchildren (48% boys) aged 7-14 years old from 8 public and 4 private schools were studied. Anthropometric and haemoglobin measurements, along with thyroid palpation, were performed. Serum retinol was measured in a random sub-sample of children (N = 173). WHO criteria were used to assess nutritional status. Chi square and independent t-test were used for proportions and mean comparisons between groups. Results Mean age of the children (48% boys) was 11.5 ± 1.2 years. Micronutrient malnutrition was highly prevalent, with 38.7% low serum retinol and 40.4% anaemia. The prevalence of stunting was 8.8% and that of thinness, 13.7%. The prevalence of anaemia (p = 0.001) and vitamin A deficiency (p < 0.001) was significantly higher in public than private schools. Goitre was not detected. Overweight/obesity was low (2.3%) and affected significantly more children in private schools (p = 0.009) and younger children (7-9 y) (p < 0.05). Thinness and stunting were significantly higher in peri-urban compared to urban schools (p < 0.05 and p = 0.004 respectively). Almost 15% of the children presented at least two nutritional deficiencies. Conclusion This study shows that malnutrition and micronutrient deficiencies are also widely prevalent in schoolchildren in

The aim of this study was to investigate the association between trichuriasis and iron status in rural schoolchildren from Northwest Mexico. A total of 73 schoolchildren (37 boys, 36 girls) between the ages of 6 and 10 years were voluntarily recruited from the public primary school of the rural community of El Higueral in Culiacan, Sinaloa (Northwest Mexico) for a cross-sectional study with a longitudinal follow-up of 5 weeks. Data were collected on socioeconomic status, anthropometry, haematological and biochemical indices of iron status, daily iron intake, and prevalence and intensity of trichuriasis. Multiple regression models, independent t-test and paired t-test were used to analyse the association between trichuriasis and iron status in cross-sectional and longitudinal samples, respectively. Adjusted models were tested for linear regression assumptions using residual plots. The mean age of the Trichuris-free and Trichuris-infected groups was 7.7±1.3 and 7.7±1.5 years respectively (P=0.92). The height for age was significantly higher in the Trichuris-free group than the Trichuris-infected group (P=0.02). No differences were found in the socioeconomic variables between the two groups. At baseline, significantly higher concentrations of haemoglobin, haematocrit, blood cell count (RBC) and serum iron were measured in the Trichuris-free group compared with the Trichuris-infected children (P<0.05). An association was found between trichuriasis and haemoglobin adjusted for socioeconomic variables, age and sex. Haemoglobin, RBC and serum ferritin concentrations were significantly increased in the infected children 5 weeks after treatment (P<0.05). Trichuriasis could be a risk factor for low-iron status in the schoolchildren of Northwest Mexico.

To compare the changes in cardiorespiratory fitness in evaluations performed every ten years since 1978/1980, according to the nutritional status and gender of students in the city of Ilhabela, Brazil. The study is part of the Mixed Longitudinal Project on Growth, Development and Physical Fitness of Ilhabela. The study included 1,291 students of both genders, aged 10 to 11 years old. The study periods were: 1978/1980, 1988/1990, 1998/2000, and 2008/2010. The variables analyzed were: body weight, height, and cardiorespiratory fitness (VO2max - L.min-1 and mL.kg-1.min-1) performed using a submaximal progressive protocol on a cycle ergometer. Individuals were classified as normal weight and overweight according to curves proposed by the World Health Organization of body mass index for age and gender. Analysis of variance (ANOVA) with three factors followed by the Bonferroni method were used to compare the periods. The number of normal weight individuals (61%) was higher than that of overweight. There was a significant decrease in cardiorespiratory fitness in both genders. Among the schoolchildren with normal weight, there was a decrease of 22% in males and 26% in females. In overweight schoolchildren, males showed a decrease of 12.7% and females, of 18%. During a 30-year analysis with reviews every ten years from 1978/1980, there was a significant decrease in cardiorespiratory fitness in schoolchildren of both genders, which cannot be explained by the nutritional status. The decline in cardiorespiratory fitness was greater in individuals with normal weight than in overweight individuals. Copyright © 2013 Sociedade Brasileira de Pediatria.

Background Fever is the clinical hallmark of malaria disease. The Roll Back Malaria (RBM) movement promotes prompt, effective treatment of childhood fevers as a key component to achieving its optimistic mortality reduction goals by 2010. A neglected concern is how communities will access these new medicines promptly and the costs to poor households when they are located in rural areas distant to health services. Methods We assemble data developed between 2001 and 2002 in Kenya to describe treatment choices made by rural households to treat a child's fever and the related costs to households. Using a cost-of-illness approach, we estimate the expected cost of a childhood fever to Kenyan households in 2002. We develop two scenarios to explore how expected costs to households would change if more children were treated at a health care facility with an effective antimalarial within 48 hours of fever onset. Results 30% of uncomplicated fevers were managed at home with modern medicines, 38% were taken to a health care facility (HCF), and 32% were managed at home without the use of modern medicines. Direct household cash expenditures were estimated at $0.44 per fever, while the total expected cost to households (cash and time) of an uncomplicated childhood fever is estimated to be $1.91. An estimated mean of 1.42 days of caretaker time devoted to each fever accounts for the majority of household costs of managing fevers. The aggregate cost to Kenyan households of managing uncomplicated childhood fevers was at least $96 million in 2002, equivalent to 1.00% of the Kenyan GDP. Fewer than 8% of all fevers were treated with an antimalarial drug within 24 hours of fever onset, while 17.5% were treated within 48 hours at a HCF. To achieve an increase from 17.5% to 33% of fevers treated with an antimalarial drug within 48 hours at a HCF (Scenario 1), children already being taken to a HCF would need to be taken earlier. Under this scenario, direct cash expenditures would not change

[Characteristics of physical growth of schoolchildren in Mongolia and their forming factors].
Pogorelova, I G; Amgalan, G
The article considers the findings of hygienic assessments of educational conditions in urban and rural schools in Mongolia and socio-economic conditions of living of schoolchildren and analysis of anthropometric measurements of schoolchildren aged of 7-16 years in relation to the assessment of harmonicity of their physical development. Hygienic conditions in Mongolian schools are characterized by improper organization of the educational - accomplishment process, high occupancy rate in classes causing insufficient space for a pupil and disconformity of school furniture parameters of school desks and chairs to growth and age requirements of pupils. Comparative assessment of socio-economic factors revealed (выделено автором) that the majority (84.1%) of rural pupils reside in uncomfortable houses and gerdwellings, 58.5 % - in large families with many children, 46.3 % - in families with poor living conditions. There were obtained data about differences in physical development of urban and rural schoolchildren pronounced with age by the gain in the number of children with disharmonious development and children with lower physical indices of the development, delayed by 1-2 years appearance of the crossing of growth and growth shift typical for rural children in comparison with their urban counterparts. According to results of multivariate regression analysis most significant factors for the formation of physical development of school children in descending order are academic workload, the place of residence, the number of children in the family, uncomfortable living conditions, household income and parent’s education. In the presence of these factors, the risk of the formation of disharmonious physical growth of school children increases by 1.8-2.8 times. The probability of the risk offormation of disharmonious physical development of schoolchildren living in rural areas was found to be by 2.5 times more than for their urban counterparts. The results

Giardiasis is a human health concern worldwide, especially among schoolchildren. Giardia duodenalis genotypes A and B are infective to humans, but their zoonotic potential remains controversial. In Mexico, the most prevalent genotype is A, but B was also detected in southeastern Mexico. In Sinaloa state, northwestern Mexico, giardiasis is highly prevalent, but Giardia genotypes have been poorly studied. This study aimed to investigate the distribution and clinical-epidemiological correlation of G. duodenalis genotypes in schoolchildren and their families and pets in urban and rural areas of Sinaloa state, Mexico. Among 395 schoolchildren (274 urban, 121 rural), 76 (49 urban, 27 rural) were infected with G. duodenalis. In total, 22 families (15 urban, 7 rural) of infected schoolchildren, consisting of 60 family members (41 urban, 19 rural) and 21 pet dogs (15 urban, 6 rural) were examined; 10 family members (5 urban, 5 rural) and 5 pet dogs (3 urban, 2 rural) of 10 families (6 urban, 4 rural) were infected. After PCR-RFLP analyses of vsp417 and gdh genes, genotype prevalence among infected urban schoolchildren was 79.5% AI, 12.8% AII, and 7.7% mixed AI+B. However, only AI genotype was found in family members and pets. In the rural area, only the AI genotype was detected. Genotypes were not correlated with clinical manifestations. This paper shows the presence of B genotype in northwestern Mexico for the first time. Detection of AI genotype in dogs suggested the possible role of dogs as the reservoir for human giardiasis in Sinaloa, Mexico.

Rural residence is protective against atopy and wheeze-rhinitis-eczema symptoms in developed countries, an effect attributed to farming and poor hygiene exposures. There are few data from developing countries addressing this question. We compared atopy and wheeze-rhinitis-eczema symptoms between urban and rural Ecuador, and explored the effects of farming and poor hygiene exposures. We performed cross sectional studies of schoolchildren living in rural and urban Ecuador. Data on symptoms and farming/hygiene exposures were collected by parental questionnaire, atopy by allergen skin prick test reactivity and geohelminth infections by stool examinations. Among 2526 urban and 4295 rural schoolchildren, prevalence was: atopy (10.0% vs 12.5%, p=0.06), wheeze (9.4% vs 10.1%, p=0.05), rhinitis (8.1% vs 6.4%, p=0.02) and eczema (5.9% vs 4.7%, p=0.06). A small proportion of symptoms were attributable to atopy (range 3.9-10.7%) with greater attributable fractions for respiratory symptoms observed in urban schoolchildren. Respiratory symptoms were associated with poor hygiene/farming exposures: wheeze with lack of access to potable water; and rhinitis with household pets, no bathroom facilities and contact with large farm animals. Birth order was inversely associated with respiratory symptoms. Area of residence and atopy had few effects on these associations. Urban schoolchildren living in Ecuador have a similar prevalence of atopy, eczema and wheeze but a higher prevalence of rhinitis compared with rural children. Some farming and poor hygiene exposures were associated with an increase in the prevalence of wheeze or rhinitis while birth order was inversely associated with these symptoms.

The effects of written action plans on recovery from exacerbations of chronic obstructive pulmonary disease (COPD) have not been well studied. The aims of this study were to assess the effects of adherence to a written action plan on exacerbation recovery time and unscheduled healthcare utilisation and to explore factors associated with action plan adherence. This was a 1-year prospective cohort study embedded in a randomised controlled trial. Exacerbation data were recorded for 252 patients with COPD who received a written action plan for prompt treatment of exacerbations with the instructions to initiate standing prescriptions for both antibiotics and prednisone within 3 days of exacerbation onset. Following the instructions was defined as adherence to the action plan. From the 288 exacerbations reported by 143 patients, start dates of antibiotics or prednisone were provided in 217 exacerbations reported by 119 patients (53.8% male, mean age 65.4 years, post-bronchodilator forced expiratory volume in 1 s (FEV(1)) 43.9% predicted). In 40.1% of exacerbations, patients adhered to their written action plan. Adherence reduced exacerbation recovery time with statistical (p=0.0001) and clinical (-5.8 days) significance, but did not affect unscheduled healthcare utilisation (OR 0.94, 95% CI 0.49 to 1.83). Factors associated with an increased likelihood of adherence were influenza vaccination, cardiac comorbidity, younger age and lower FEV(1) as percentage predicted. This study shows that adherence to a written action plan is associated with a reduction in exacerbation recovery time by prompt treatment. Knowing the factors that are associated with proper and prompt utilisation of an action plan permits healthcare professionals to better focus their self-management support on appropriate patients.

This study examined the impact of controllability of onset (i.e., means of transmission), disease type (HIV and lung cancer), and culture (Kenya and U.S.) on stigmatizing attitudes and goals for supportive communication. Four hundred sixty-four Kenyan students and 526 American students, and 441 Kenyan nonstudents and 591 American nonstudents were randomly assigned to 1 of 12 hypothetical scenario conditions and asked to respond to questions regarding 3 different types of stigmatizing attitudes and 6 types of supportive communication goals with respect to the character in the scenario. Means of transmission had a strong effect on the blame component of stigma, but none on cognitive attitudes and social interaction components. Similarly, although an effect for means of transmission emerged on intention to provide "recognize own responsibility" and "see others' blame" types of support, no effect was evident for most other supportive interaction goals. Although effects for culture were small, Kenyan participants, student and nonstudent alike, were not as quick as American participants to adopt goals of communicating blame in any direction. Implications for measurement of stigma in future research are discussed.

In a cross-sectional epidemiologic study of schoolchildren aged 11-17 years, the cardiac work index at exercise was found to be higher in schoolchildren with arterial hypertension (AH) and excess body weight than in the control group. The duration of an exercise test was similar in the two groups. The higher cardiac work index at exercise may be explained by considerably higher systolic blood pressure in schoolchildren with AH and by higher heart rates in those with excess body weight.

The actual nutrition of schoolchildren in the Nizni-Novgorod district is imbalanced due to the deficiency of protein and vitamins and to the high contents of fats and carbohydrates. The authors provide evidence for a combined preparation to correct the children's diets, which incorporates animal protein, biologically active plant additives, and egg-shell calcium. The use of the preparation in combination with liquid bifidumbacterin contributes to increases in morphofunctional parameters in adolescents.

The paper presents the results of studying the impact of using cellular phones and personal computers on the health status of 277 Saratov schoolchildren (mean age 13.2 +/- 2.3 years). About 80% of the adolescents have been ascertained to use cellular phones and computers mainly for game purposes. The active users of cellular phones and computers show a high aggressiveness, anxiety, hostility, and social stress, low stress resistance, and susceptibility to arterial hypotension. The negative influence of cellular phones and computers on the schoolchildren's health increases with the increased duration and frequency of their use.

Summary Methods The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/ obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit. Data are reported as prevalence (95% confidence intervals) and association (r, Pearson). Results Prevalence of overweight/obesity was 17.7% (12.4–23.0%), high blood pressure (BP < 90% percentile) was 14.6% (9.7–19.5%), elevated glucose level was 16.7% (11.5–21.9%) and total cholesterol level < 170 mg/dl (4.4 mmol/l) was 69.2% (62.8–75.6%). Significant associations between body mass index (BMI) and systolic and diastolic BP (r = 0.46 and 0.40, respectively; p < 0.05) were found. No association between BMI and elevated glucose or cholesterol levels was found. Conclusion The prevalence of cardiovascular risk factors was high in pre-pubertal schoolchildren in Angola and fat accumulation was directly associated with blood pressure increase but not with other cardiovascular risk factors.

Breakfast food patterns among urban and rural Croatian schoolchildren.
Colic Baric, Irena; Satalic, Zvonimir
2003-01-01
The aim of this study was to report breakfast food patterns among the rural and urban Croatian schoolchildren in the post-war socioeconomic changes. A quantitative Food Frequency Questionnaire was used. Subjects were 7-18 year old schoolchildren (815 from urban and 375 from rural areas). The average energy intake was 27.5 and 23.0% of the Recommended Dietary Allowance (RDA) in the urban and rural area respectively. Urban subjects tend to choose healthier options when older, while the rural subjects displayed the opposite (significantly correlated age with energy intake (% RDA) and dietary fibre intake (% of 'age + 5' rule). The same applied to age versus iron intake (urban positive, rural negative correlation). Breakfasts providing 20-30% RDA for energy and more than 300 mg of calcium were consumed by 20.7 and 32.4% of the urban and rural subjects respectively. Cereal products and milk and dairy products were the major breakfast constituents everywhere. Meat and its products, and eggs seem to be uncommon breakfast foods. The urban subjects had a more adequate energy intake at breakfast, but better food choices were observed among rural subjects.

Pediatric obesity has become a problem of epidemic proportions, due to the inadequate and excessive consumption of food, sedentary lifestyle, and the restricted socio-economic development. This causes a major risk in health complications that have an effect on the psychological and social spheres of the child, which makes him endure such diseases as depression and anxiety. The aim of this study was to determine the association between depression and the nutritional status of schoolchildren from a family medicine unit in Sonora. Cross-sectional study performed during 2011 in 101 schoolchildren from Sonora. Kovacs test was applied to detect depressive symptoms; nutritional status was determined by weight and height; body mass index was calculated according to the Center for Disease Control and Prevention (CDC) percentiles. The results were analyzed in SPSS version 18 using Mann-Whitney U and chi-square. Of all the patients with depression, 19 were obese; the other 10 showed a normal nutrition status. Patients with low weight did not show depression. The odds ratio (OR) for depression in students with obesity was 3.16, 95 % CI = 1.13, 7.12. The detection and management of depression should be considered in the treatment of obesity.

Aim To investigate the prevalence of dental caries and treatment needs in schoolchildren aged 7-14 years from Zagreb. Methods Dental examinations based on the World Health Organization criteria were performed on 1168 children in the period 2009-2010. The teeth were clinically examined with standard dental instruments using visual-tactile method under standard dental light. We recorded the clinical indexes of decayed, missed, and filled teeth (DMFT and dmft; upper-case letters refer to permanent and lower-case letters to primary teeth) and decayed, missed, and filled surfaces (DMFS), as well as the significant caries index (SiC). Results The median DMFT and DMFS of all children were 3 and 4, respectively. The median DMFT and DMFS of 12-year-old children were 4 and 5, respectively. The highest median DMFT score of 7 was found among 14-year-old children. There was a significant difference between age groups (7-10 years and 11-14 years) in DMFT and DMFS. Among 8-year-old children, the median dmft index was the highest (5.5) and SiC index was 7.4. As far as the location of caries on the surface of the first permanent molar is concerned, caries occurred mostly in the central occlusal surface (27.6%).

Long-term outcome prediction in COPD is challenging. We conducted a prospective 5-7-year follow-up study in patients with COPD to determine the association of exacerbation type, discharge levels of inflammatory biomarkers including procalctionin (PCT), C-reactive protein (CRP), white blood cell count (WBC) and plasma proadrenomedullin (ProADM), alone or combined with demographic/clinical characteristics, with long-term all-cause mortality in the COPD setting. The analyzed cohort comprised 469 patients with index hospitalization for pneumonic (n = 252) or non-pneumonic (n = 217) COPD exacerbation. Five-to-seven-year vital status was ascertained via structured phone interviews with patients or their household members/primary care physicians. We investigated predictive accuracy using univariate and multivariate Cox regression models and area under the receiver operating characteristic curve (AUC). After a median [25th-75th percentile] 6.1 [5.6-6.5] years, mortality was 55% (95%CI 50%-59%). Discharge ProADM concentration was strongly associated with 5-7-year non-survival: adjusted hazard ratio (HR)/10-fold increase (95%CI) 10.4 (6.2-17.7). Weaker associations were found for PCT and no significant associations were found for CRP or WBC. Combining ProADM with demographic/clinical variables including age, smoking status, BMI, New York Heart Association dyspnea class, exacerbation type, and comorbidities significantly improved long-term predictive accuracy over that of the demographic/clinical model alone: AUC (95%CI) 0.745 (0.701-0.789) versus 0.727 (0.681-0.772), (p) = .043. In patients hospitalized for COPD exacerbation, discharge ProADM levels appeared to accurately predict 5-7-year all-cause mortality and to improve long-term prognostic accuracy of multidimensional demographic/clinical mortality risk assessment.

Mandatory fortification of bread with iodized salt was introduced in Australia in 2009, and studies using spot urine collections conducted post fortification indicate that Australian schoolchildren are now replete. However an accurate estimate of daily iodine intake utilizing 24-h urinary iodine excretion (UIE μg/day) has not been reported and compared to the estimated average requirement (EAR). This study aimed to assess daily total iodine intake and status of a sample of primary schoolchildren using 24-h urine samples. Victorian primary school children provided 24-h urine samples between 2011 and 2013, from which urinary iodine concentration (UIC, μg/L) and total iodine excretion (UIE, μg/day) as an estimate of intake was determined. Valid 24-h urine samples were provided by 650 children, mean (SD) age 9.3 (1.8) years (n = 359 boys). The mean UIE of 4–8 and 9–13 year olds was 94 (48) and 111 (57) μg/24-h, respectively, with 29% and 26% having a UIE below the age-specific EAR. The median (IQR) UIC was 124 (83,172) μg/L, with 36% of participants having a UIC < 100 μg/L. This convenience sample of Victorian schoolchildren were found to be iodine replete, based on UIC and estimated iodine intakes derived from 24-h urine collections, confirming the findings of the Australian Health Survey.

Echinococcosis is a serious zoonotic parasitic disease that is highly endemic in Qinghai Province. The present study aimed to investigate the prevalence of echinococcosis among schoolchildren in Golog Tibetan Autonomous Prefecture to improve early diagnosis and treatment of patients and to provide information for echinococcosis prevention and control. A total of 11,260 schoolchildren from five counties (Maqin, Gander, Dari, Jiuzhi, and Banma) in Golog Tibetan Autonomous Prefecture, Qinghai Province, were screened for echinococcosis. Screening involved ultrasound imaging combined with serologic examination as an auxiliary diagnostic test. The prevalence of echinococcosis in the schoolchildren was 2.1% (235/11,260), with a rate of 0.8% for cystic echinococcosis (CE; 89/11,260) and 1.3% for alveolar echinococcosis (AE; 146/11,260). Additionally, one child had a mixed infection. The prevalence ranged between 1.1% and 4.1% among the five investigated counties, and was highest in Dari County (4.1%). The prevalence of echinococcosis was higher in girls than in boys and gradually increased with age. In addition, children with CE mainly had type 1 (CE1) and type 3 (CE3) lesions, and children with AE mainly had small-diameter calcified lesions, suggesting that they were in the early asymptomatic stage of echinococcosis. In conclusion, children of Golog Tibetan Autonomous Prefecture appear to exhibit the highest recorded prevalence of CE and AE globally. Ultrasound is useful for screening populations in regions where both CE and AE are endemic.

In spite of their enormous importance, permanent first molars might be affected by caries in children in developing countries. The aim of this study was to evaluate the treatment needs of first permanent molars in a group of schoolchildren in Mashhad. This cross-sectional descriptive study was carried out on 700, 7-9 year-old students in primary schools in Mashhad. The schools were randomly selected from each district. Treatment needs and DMFT of first perma-nent molars were calculated. Data was analyzed using ANOVA, Chi-Square and t-test. A total of 95.3% of the children required dental treatment. Fissure sealant application and filling were the treat-ments most required in all age groups. The mean DMFT of first permanent molars was 1.31±1.4. It was significantly higher in girls than boys (P=0.040). Great treatment needs and caries prevalence in permanent first molars in Mashhad schoolchildren show that dental caries is still a serious problem in the children of our society; therefore, education of parents and teachers is necessary for promoting children's oral health.

The objective this study was to investigate the influence of clinical conditions, socioeconomic status, home environment, subjective perceptions of parents and schoolchildren about general and oral health on schoolchildren's oral health-related quality of life (OHRQoL). A sample of 515 schoolchildren, aged 12 years was randomly selected by conglomerate analysis from public and private schools in the city of Juiz de Fora, Brazil. The schoolchildren were clinically examined for presence of caries lesions (DMFT and dmft index), dental trauma, enamel defects, periodontal status (presence/absence of bleeding), dental treatment and orthodontic treatment needs (DAI). The SiC index was calculated. The participants were asked to complete the Brazilian version of Child Perceptions Questionnaire (CPQ11-14) and a questionnaire about home environment. Questions were asked about the presence of general diseases and children's self-perception of their general and oral health status. In addition, a questionnaire was sent to their parents inquiring about their socioeconomic status (family income, parents' education level, home ownership) and perceptions about the general and oral health of their school-aged children. The chi-square test was used for comparisons between proportions. Poisson's regression was used for multivariate analysis with adjustment for variances. Univariate analysis revealed that school type, monthly family income, mother's education, family structure, number of siblings, use of cigarettes, alcohol and drugs in the family, parents' perception of oral health of schoolchildren, schoolchildren's self perception their general and oral health, orthodontic treatment needs were significantly associated with poor OHRQoL (p < 0.001). After adjusting for potential confounders, variables were included in a Multivariate Poisson regression. It was found that the variables children's self perception of their oral health status, monthly family income, gender, orthodontic

To investigate the prevalence of inaccurate estimation of own body size among Brazilian schoolchildren of both sexes aged 7-10 years, and to test whether overweight/obesity; excess body fat and central obesity are associated with inaccuracy. Accuracy of body size estimation was assessed using the Figure Rating Scale for Brazilian Children. Multinomial logistic regression was used to analyze associations. The overall prevalence of inaccurate body size estimation was 76%, with 34% of the children underestimating their body size and 42% overestimating their body size. Obesity measured by body mass index was associated with underestimation of body size in both sexes, while central obesity was only associated with overestimation of body size among girls. The results of this study suggest there is a high prevalence of inaccurate body size estimation and that inaccurate estimation is associated with obesity. Accurate estimation of own body size is important among obese schoolchildren because it may be the first step towards adopting healthy lifestyle behaviors.

With increasing health care costs that have outpaced those of other industries, payers of health care are moving from a fee-for-service payment model to one in which reimbursement is tied to outcomes. Chronic obstructive pulmonary disease (COPD) is a disease where this payment model has been implemented by some payers, and COPD exacerbations are a quality metric that is used. Under an outcomes-based payment model, it is important for health systems to be able to identify patients at risk for poor outcomes so that they can target interventions to improve outcomes. To develop and evaluate predictive models that could be used to identify patients at high risk for COPD exacerbations. This study was retrospective and observational and included COPD patients treated with a bronchodilator-based combination therapy. We used health insurance claims data to obtain demographics, enrollment information, comorbidities, medication use, and health care resource utilization for each patient over a 6-month baseline period. Exacerbations were examined over a 6-month outcome period and included inpatient (primary discharge diagnosis for COPD), outpatient, and emergency department (outpatient/emergency department visits with a COPD diagnosis plus an acute prescription for an antibiotic or corticosteroid within 5 days) exacerbations. The cohort was split into training (75%) and validation (25%) sets. Within the training cohort, stepwise logistic regression models were created to evaluate risk of exacerbations based on factors measured during the baseline period. Models were evaluated using sensitivity, specificity, and positive and negative predictive values. The base model included all confounding or effect modifier covariates. Several other models were explored using different sets of observations and variables to determine the best predictive model. There were 478,772 patients included in the analytic sample, of which 40.5% had exacerbations during the outcome period. Patients with

Asthma exacerbations occur frequently despite the regular use of asthma-controller therapies, such as inhaled glucocorticoids. Clinicians commonly increase the doses of inhaled glucocorticoids at early signs of loss of asthma control. However, data on the safety and efficacy of this strategy in children are limited. We studied 254 children, 5 to 11 years of age, who had mild-to-moderate persistent asthma and had had at least one asthma exacerbation treated with systemic glucocorticoids in the previous year. Children were treated for 48 weeks with maintenance low-dose inhaled glucocorticoids (fluticasone propionate at a dose of 44 μg per inhalation, two inhalations twice daily) and were randomly assigned to either continue the same dose (low-dose group) or use a quintupled dose (high-dose group; fluticasone at a dose of 220 μg per inhalation, two inhalations twice daily) for 7 days at the early signs of loss of asthma control ("yellow zone"). Treatment was provided in a double-blind fashion. The primary outcome was the rate of severe asthma exacerbations treated with systemic glucocorticoids. The rate of severe asthma exacerbations treated with systemic glucocorticoids did not differ significantly between groups (0.48 exacerbations per year in the high-dose group and 0.37 exacerbations per year in the low-dose group; relative rate, 1.3; 95% confidence interval, 0.8 to 2.1; P=0.30). The time to the first exacerbation, the rate of treatment failure, symptom scores, and albuterol use during yellow-zone episodes did not differ significantly between groups. The total glucocorticoid exposure was 16% higher in the high-dose group than in the low-dose group. The difference in linear growth between the high-dose group and the low-dose group was -0.23 cm per year (P=0.06). In children with mild-to-moderate persistent asthma treated with daily inhaled glucocorticoids, quintupling the dose at the early signs of loss of asthma control did not reduce the rate of severe asthma

We studied the prevalence of obesity and overweight in schoolchildren aged 5-8 years in Tebessa, Algeria between 1998 and 2005. All schoolchildren in 5 primary schools (n = 3396) were included. Age, sex, height and weight were recorded. For classification of obesity and overweight the International Obesity Task Force definitions was used. The prevalence of obesity and overweight for the total sample was 6.36% and fell from 7.44% in 1998 to 5.81% in 2005. The prevalence of obesity was higher in girls than boys (1.58% vs 1.26%) (P = 0.430) while the prevalence of overweight was higher in boys than girls (5.60% vs 4.18%) (P = 0.057).

The purpose of this investigation was to determine the effects of 28 weeks of high-intensity interval training (HIIT) during physical education classes on the weight status, cardiorespiratory capacity, and blood pressure of overweight and obese schoolchildren. The participants included 197 schoolchildren (108 girls and 89 boys) aged between 6 and 11 years (8.39 ± 1.15 years) in four groups: experimental group 1 (EG1) = 59 overweight schoolchildren; experimental group 2 (EG2) = 92 obese schoolchildren; control group 1 (CG1) = 17 overweight children; and control group 2 (CG2) = 29 obese schoolchildren. The participants in the EGs carried out HIIT twice per week for 28 weeks. After the 28-week intervention, the participants showed significant reductions in body mass index (p < 0.001). Waist circumference of boys in EG2 and waist-to-height ratio of girls in EG2 was significantly reduced (p < 0.05). Body fat percentage diminished, for girls in both groups and boys in EG2 (p < 0.05). Furthermore, the program significantly reduced the number of hypertensive schoolchildren (p = 0.001) and reduced the percentage of obese schoolchildren. The distance covered in the 6-min walk test improved significantly for girls in EG1 and EG2 (p < 0.05) and boys in EG2. The 28-week HIIT program caused significant improvements in the cardiorespiratory capacity, anthropometric variables, and blood pressure levels of overweight and obese children. What is Known: • High-intensity interval training (HIIT) programs improve health, but investigations have used relatively short intervention periods. What is New: • The 28-week period (a large intervention period) of HIIT-based games during physical education classes caused significant improvements in cardiorespiratory capacity, anthropometric variables, and blood pressure levels of overweight and obese schoolchildren.

To examine factors potentially contributing to acutely exacerbated chronic tinnitus initiation using the Tinnitus Handicap Inventory. Sixty acutely exacerbated chronic tinnitus out-patients were divided into two groups depending on whether hearing loss was aggravated or stable during tinnitus exacerbation. Total Tinnitus Handicap Inventory scores and scores for the three subscales (assessing functional limitations, emotional attitudes and catastrophic thoughts) were analysed. Total Tinnitus Handicap Inventory scores did not differ between groups. In patients with acutely exacerbated chronic tinnitus and aggravated hearing loss, functional subscale scores were significantly higher after acutely exacerbated chronic tinnitus than at baseline, but catastrophic and emotional subscale scores did not change. In patients with acutely exacerbated chronic tinnitus and stable hearing loss, emotional subscale scores were significantly higher after acutely exacerbated chronic tinnitus than at baseline, but catastrophic and functional subscale scores did not change. Elevated Tinnitus Handicap Inventory functional subscale scores might indicate further hearing loss, whereas elevated emotional subscale scores might be associated with negative life or work events.

Emotional symptoms are widespread among adolescents with the highest prevalence among lower socioeconomic groups. Less is known about why and how to reduce this inequality but personal control, e.g., self-efficacy may be crucial. This study examines whether self-efficacy is a mediator in the association between occupational social class (OSC) and emotional symptoms. Data stem from the cross-sectional Health Behavior in School-aged Children-Methodology Development Survey 2012 (HBSC-MDS) conducted among 11-15-year old schoolchildren in two Danish municipalities. Participation rate was 76.8 % of 5165 enrolled schoolchildren, n = 3969. Low OSC is associated with higher odds of daily emotional symptoms and low selfefficacy. Schoolchildren with low self-efficacy have higher odds for daily emotional symptoms. We find a strong and statistically significant direct effect between low OSC and daily emotional symptoms (OR = 1.55, 95 % CI: 1.33; 1.84) and a borderline statistically significant indirect effect of self-efficacy [OR = 1.17 (0.99; 1.38)]. Socioeconomic inequality in emotional symptoms exists. This inequality is partly explained by socioeconomic inequality in self-efficacy. Promotion of personal competences like self-efficacy may reduce emotional symptoms among all socioeconomic groups, thereby reducing socioeconomic inequalities in emotional symptoms.

To determine the incidence of dengue infection, we established active surveillance of febrile episodes in a cohort of schoolchildren from three schools in Medellin, Colombia. We followed a cohort of 2,379 schoolchildren in 2010 and followed 1,840 of these children the following year. During the follow-up time, 264 schoolchildren displayed 297 febrile episodes; of these, 23 episodes (7.7%) were caused by acute dengue infection. All four dengue serotypes were found, and all of the cases were mild. The most common symptoms in the dengue cases compared with those in other febrile illness were asthenia (96% versus 87%), anorexia (78% versus 57%), rhinorrhea (65.2% versus 58%), abdominal pain (56.5% versus 47.8%), arthralgia (43% versus 33%), and positive tourniquet test (13% versus 3%). This difference was not statistically significant. Pulse was elevated, and systolic arterial pressure was lower in dengue cases compared with other febrile illness (P < 0.05). Mosquito indexes were determined in 8 children's houses and in the schools. Aedes aegypti adults were found in both households and in schools, whereas Aedes aegypti larvae were found only in schools. These results showed an elevated dengue frequency in children, with symptoms similar to those of other febrile illness and transmission risk in households and schools. PMID:23304167

To assess the association between the air pollutants exposure on markers of oxidative stress and lung function in schoolchildren with and without asthma from Salamanca and Leon Guanajuato, Mexico. We realized determinations of oxidative stress biomarkers and lung function tests in 314 schoolchildren. Information of air pollutants (O3, SO2, CO, PM2.5 and PM10) were obtained from monitoring stations and multiple linear regression models were run to assess the association. An increase of 0.09 pmol in conjugated dienes was observed by exposure to PM10 lag 1 in asthmatics from Salamanca (p<0.05). The exposure to O3 during the same day increased the concentration of Lipohydroperoxides in 4.38 nmol in asthmatics of Salamanca, as well as in 2.31 nmol by exposure to PM10 lag 2 (p<0.05). The forced vital capacity decreased by 138 and 203 ml in children without asthma, respectively, due to exposure to carbon monoxide (p<0.05). Exposure to air pollutants increase oxidative stress and decreased lung function in schoolchildren, with and without asthma.
A new method for examining the cost savings of reducing COPD exacerbations.

Some treatments for chronic obstructive pulmonary disease (COPD) can reduce exacerbations, and thus could have a favourable impact on overall healthcare costs. To evaluate a new method for assessing the potential cost savings of COPD controller medications based on the incidence of exacerbations and their related resource utilization in the general population. Patients with COPD (n = 1074) enrolled in a regional managed care system in the US were identified using administrative data and divided by their medication use into three groups (salbutamol, ipratropium and salmeterol). Exacerbations were captured using International Classification of Diseases, Ninth Edition (ICD-9) and current procedural terminology (CPT) codes, then logistic regression models were created that described the risk of exacerbations for each comparator group and exacerbation type over a 6-month period. A Monte Carlo simulation was then applied 1000 times to provide the range of potential exacerbation reductions and cost consequences in response to a range of hypothetical examples of COPD controller medications. Exacerbation events for each group could be modelled such that the events predicted by the Monte Carlo estimates were very close to the actual prevalences. The estimated cost per exacerbation avoided depended on the incidence of exacerbation in the various subpopulations, the assumed relative risk reduction, the projected daily cost for new therapy, and the costs of exacerbation treatment. COPD exacerbation events can be accurately modelled from the healthcare utilization data of a defined cohort with sufficient accuracy for cost-effectiveness analysis. Treatments that reduce the risk or severity of exacerbations are likely to be cost effective among those patients who have frequent exacerbations and hospitalizations.

To evaluate a multipronged approach to promote dual contraceptive use by women within heterosexual HIV-1-serodiscordant partnerships. For 213 HIV-1-serodiscordant couples in Thika, Kenya, participating in an HIV-1 prevention clinical trial, contraceptive promotion was initiated through a multipronged intervention that included staff training, couples family planning sessions, and free provision of hormonal contraception on-site. Contraceptive use and pregnancy incidence were compared between two time periods (before versus after June 2007, when the intervention was initiated) and between Thika and other Kenyan trial sites (Eldoret, Kisumu, and Nairobi). Generalized estimating equations and Andersen-Gill proportional hazards modeling were used. Nonbarrier contraceptive use increased after implementation of the intervention: from 31.5 to 64.7% of visits among HIV-1-seropositive women [odds ratio 4.0, 95% confidence interval (CI) 3.0-5.3] and from 28.6 to 46.7% of visits among HIV-1-seronegative women (odds ratio 2.2, 95% CI 1.4-3.5). In comparison, at the other Kenyan sites, where the intervention was not implemented, contraceptive use changed minimally, from 15.6 to 22.3% of visits for HIV-1-seropositive women and from 13.6 to 12.7% among HIV-1-seronegative women. Self-reported condom use remained high during follow-up. Pregnancy incidence at the Thika was significantly lower after compared with before June 2007 (hazard ratio 0.2, 95% CI 0.1-0.6) and was approximately half that at other Kenyan sites during the intervention period (hazard ratio 0.5, 95% CI 0.3-0.8). A multipronged family planning intervention can lead to high nonbarrier contraceptive uptake and reduced pregnancy incidence among women in HIV-1-serodiscordant partnerships.

Bronchiectasis unrelated to cystic fibrosis (CF) is being increasingly recognized in children and adults globally, both in resource-poor and in affluent countries. However, high-quality evidence to inform management is scarce. Oral amoxycillin-clavulanate is often the first antibiotic chosen for non-severe respiratory exacerbations, because of the antibiotic-susceptibility patterns detected in the respiratory pathogens commonly associated with bronchiectasis. Azithromycin has a prolonged half-life, and with its unique anti-bacterial, immunomodulatory, and anti-inflammatory properties, presents an attractive alternative. Our proposed study will test the hypothesis that oral azithromycin is non-inferior (within a 20% margin) to amoxycillin-clavulanate at achieving resolution of non-severe respiratory exacerbations by day 21 of treatment in children with non-CF bronchiectasis. This will be a multicenter, randomized, double-blind, double-dummy, placebo-controlled, parallel group trial involving six Australian and New Zealand centers. In total, 170 eligible children will be stratified by site and bronchiectasis etiology, and randomized (allocation concealed) to receive: 1) azithromycin (5 mg/kg daily) with placebo amoxycillin-clavulanate or 2) amoxycillin-clavulanate (22.5 mg/kg twice daily) with placebo azithromycin for 21 days as treatment for non-severe respiratory exacerbations. Clinical data and a parent-proxy cough-specific quality of life (PC-QOL) score will be obtained at baseline, at the start and resolution of exacerbations, and on day 21. In most children, blood and deep-nasal swabs will also be collected at the same time points. The primary outcome is the proportion of children whose exacerbations have resolved at day 21. The main secondary outcome is the PC-QOL score. Other outcomes are: time to next exacerbation; requirement for hospitalization; duration of exacerbation, and spirometry data.

How best to teach CPR to schoolchildren: a systematic review.
Plant, Nina; Taylor, Katherine
2013-04-01
Training schoolchildren to perform cardiopulmonary resuscitation is one possible method of increasing bystander CPR rates. We reviewed available literature to identify what methods of training children have been successful. This review sought to evaluate evidence addressing the following PICO question: (P) In schoolchildren, (I) what types of CPR, AED and first aid training (C) when compared to no training and to each other (O) lead to ability to perform life saving measures? Searches were conducted in Ovid MEDLINE (1946 - August 2012), Ovid EMBASE (1974 - August 2012) and Ebscohost Cinahl (1981 - August 2012). Database specific subject headings in all three databases (MeSH in MEDLINE, Emtree in EMBASE, Cinahl Headings) were selected for the concepts of cardiopulmonary resuscitation (CPR) and education. The combined results were then limited by age to include all school aged children. The search yielded 2620 articles. From titles, abstract and key words, 208 articles described CPR, AED and/or first aid training in schoolchildren and were eligible for review. These were obtained in full, were unavailable or not published in English. We reviewed articles for publication type and relevance. 48 studies were identified. One additional study was included as an extension of a study retrieved within the search. The studies found by the search were heterogeneous for study and training methodology. Findings regarding schoolchild age and physical factors, the role of practical training, use of self-instruction kits, use of computer based learning, reduced training time, trainer type, AED training are presented. Evidence shows that cardiopulmonary training, delivered in various ways, is successful in a wide age range of children. While older children perform more successfully on testing, younger children are able to perform basic tasks well, including use of AEDs. Chest compression depth correlates with physical factors such as increasing weight, BMI and height. Instruction

Asthma exacerbations are frightening for patients and are occasionally fatal. We tested the concept that a plan for patients to manage their asthma (self-management plan), which included a temporary quadrupling of the dose of inhaled glucocorticoids when asthma control started to deteriorate, would reduce the incidence of severe asthma exacerbations among adults and adolescents with asthma. We conducted a pragmatic, unblinded, randomized trial involving adults and adolescents with asthma who were receiving inhaled glucocorticoids, with or without add-on therapy, and who had had at least one exacerbation in the previous 12 months. We compared a self-management plan that included an increase in the dose of inhaled glucocorticoids by a factor of 4 (quadrupling group) with the same plan without such an increase (non-quadrupling group), over a period of 12 months. The primary outcome was the time to a first severe asthma exacerbation, defined as treatment with systemic glucocorticoids or an unscheduled health care consultation for asthma. A total of 1922 participants underwent randomization, of whom 1871 were included in the primary analysis. The number of participants who had a severe asthma exacerbation in the year after randomization was 420 (45%) in the quadrupling group as compared with 484 (52%) in the non-quadrupling group, with an adjusted hazard ratio for the time to a first severe exacerbation of 0.81 (95% confidence interval, 0.71 to 0.92; P=0.002). The rate of adverse effects, which were related primarily to local effects of inhaled glucocorticoids, was higher in the quadrupling group than in the non-quadrupling group. In this trial involving adults and adolescents with asthma, a personalized self-management plan that included a temporary quadrupling of the dose of inhaled glucocorticoids when asthma control started to deteriorate resulted in fewer severe asthma exacerbations than a plan in which the dose was not increased.

Verify the association between metabolic risk profile in students with different levels of cardiorespiratory fitness and body mass index, as well as the nutritional status of their parents. A cross-sectional study comprising 1.254 schoolchildren aged between seven and 17 years. The metabolic risk profile was calculated by summing the standardized values of high density lipoproteins and low density lipoproteins, triglycerides, glucose and systolic blood pressure. The parents' nutritional status was evaluated by self-reported weight and height data, for body mass index calculating. The body mass index of schoolchildren was classified as underweight/normal weight and overweight/obesity. The cardiorespiratory fitness was assessed by 9-minute running/walk test, being categorized as fit (good levels) and unfit (low levels). Data were analyzed using prevalence ratio values (PR). The data indicates a higher occurrence of developing metabolic risk in schoolchildren whose mother is obese (PR: 1.50; 95% CI: 1.01, 2.23), and even higher for those whose father and mother are obese (PR: 2, 79, 95% CI: 1.41; 5.51). Students who have low levels of cardiorespiratory fitness and overweight/obesity have higher occurrence of presenting metabolic risk profile (PR: 5.25; 95% CI: 3.31; 8.16). the occurrence of developing metabolic risk in schoolchildren increase when they have low levels of cardiorespiratory fitness and overweight/obesity, and the presence of parental obesity.

The paper explains the alterations of the temporomandibular joint (TMJ) visualized by magnetic resonance imaging (MRI) according to the growth and development of schoolchildren. Appearance and disappearance of a “double contour-like structure” (DCLS) of the mandibular condyle on MRI according to the growth and development of schoolchildren were demonstrated. In addition, possible constituents of DCLS and the significance of detection of DCLS on MRI were also speculated. The relationship between red marrow and yellow marrow in the articular eminence of temporal bone, the disappearance of DCLS, and alterations of the mandibular condyle have been elucidated.

Nonalcoholic fatty liver disease (NAFLD) is an emerging problem in children and adolescents worldwide. This study was done to investigate the prevalence of NAFLD in children and adolescents as well as to determine the associated risk factors of fatty liver and to explore the ability of some obesity indices to predict and consequently be used as a screening method of fatty liver disease at certain cutoff points in schoolchildren. A cross-sectional, nested case-control study was carried out. Cases and controls were randomly selected from outpatient schoolchildren aged 6-18years attending the radiology clinic at Sporting Health Insurance Paediatric Hospital in Alexandria. They were subjected to ultrasonic examination as well as complete anthropometric and laboratory measurements including fasting plasma glucose (FPG) level, fasting insulin, alanine aminotransferase (ALT) level, and lipid profile. Fatty liver was prevalent in schoolchildren (15.8%) and increased significantly with age (p=0.004). Positive family history of diabetes mellitus (DM), hypertension (HTN), obesity, and liver disease were all statistically significant risk factors for fatty liver. Waist circumference (WC), body mass index (BMI) and its Z-score were significantly sensitive predictors. BMI was considered the best predictor of paediatric NAFLD at a cutoff=22.9. NAFLD was significantly associated with high triglycerides (TGs), low high-density lipoprotein cholesterol (HDL), homoeostatic model assessment (HOMA) percentile, and the number of metabolic syndrome (MS) components. Paediatric NAFLD is a substantial problem in schoolchildren and has a close relationship with obesity, dyslipidaemia, insulin resistance (IR), and consequently MS. BMI and WC can be used as useful predictors and screening tools for NAFLD in schoolchildren. Copyright © 2014 Arab Journal of Gastroenterology. Published by Elsevier Ltd. All rights reserved.

The purpose of this study is to determine the correlation of socioeconomic, dietary, and anthropometric-nutritional variables of parents and their children to overweight (including obesity) in schoolchildren in Santa Catarina State, Brazil. This is a transversal study conducted on 4,964, 6 to 10-year-old schoolchildren registered in 345 Santa Catarina elementary schools. The following data were acquired: the children's current weight and height, birth weight and length, duration of breastfeeding, age at which water, herbal tea and other foods were introduced to their diet; parental income, education level, age, weight and height were also obtained. The prevalence of overweight and obese children were estimated by point and by interval with a 95% confidence; prevalence rates were obtained based on the Poisson model. An hierarchical approach was used, in which variables were adjusted within blocks and included in the model when they presented p < 0.05 at the outcome (overweight including obesity). The results indicate that 47.8% of the subjects were male. The prevalence of overweight and obese students was 15.4% (C195%: 14.4%-16.5%) and 6.1% (C195%: 5.4%-6.7%) respectively and were statistically similar among sexes and age ranges. BMI values were higher in males and among older children (p < 0.05). After adjustment within and among blocks, the variables per capita household income and parents' BMI values remained associated with overweight (including obesity). Overweight (including obesity) in schoolchildren is associated with a higher per capita household income and parental overweight and obesity.

Gingivitis is the most prevalent oral disease in children, being strongly associated to social gradients. Many studies have reported different results concerning the extent and intra-oral distribution of gingivitis in children. The aim of this study was to investigate the epidemiologic parameters and socio-related risk factors of gingivitis in the 10-17-year-old Bucharest schoolchildren population and to analyze its intra-oral distribution. Cross-sectional data were obtained from 1595 schoolchildren, social condition being assigned using a simple questionnaire. Classes of students were used as clusters in a single-stage cluster sampling method. An intra-oral exam was performed for all the children included in this study. Silness and Löe scores, prevalence and the extent of gingivitis were calculated. The gingival scores showed a mild inflammation and the prevalence of gingivitis was 91%. Boys had a higher gingival (0.19 vs. 0.18; p < 0.05) and plaque scores (0.71 vs. 0.59; p < 0.01) than girls. Children who did not live in overcrowded households, whose parents had a better education and those who had direct access to school dental services displayed better gingival conditions (p < 0.05). Gingivitis was more severe on the upper teeth, with the maximum score being reached at the right upper lateral incisor (0.63 on distal surface). Gingival condition in Bucharest schoolchildren population was associated to social gradients. School dental services are also another factor that seems to be related with gingivitis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
A Model of the Effect of Lens Development on Refraction in Schoolchildren.
He, Ji C
2017-12-01
The study provides a new theory on the mechanism underlying myopia development, and it could be useful in clinical practice to control myopia development in schoolchildren. To model the effect of the crystalline lens on refractive development in schoolchildren. The Zemax 13 was used to calculate Zernike aberrations and refractions across 50° horizontal visual fields. Optical effects of the anterior chamber depth, lens thickness, and radii of curvature of the lens surfaces on refractions were modeled. Refractive changes induced by lens development in emmetropic and myopic eyes, based on a previous longitudinal study from literature, were calculated. A lens thickness reduction with an anterior chamber depth deepening caused a hyperopic shift over the visual fields and even more at the periphery. Opposite effects were found when the lens was thinned without any change of the anterior chamber depth. While a flattening of the anterior lens surface produced hyperopic refractions overall, a posterior lens flattening caused a myopic shift at the periphery, but a hyperopic shift of the central refraction. In the myopic eye, lens development induced refractive change toward more hyperopic over the visual fields and more at the periphery. Lens thinning and lens axial movement participate in peripheral refractive development in schoolchildren, and lens development with a deeper anterior chamber depth and a flatter lens surface in the myopic eye could generate extra hyperopia over visual fields. The myopic lens development could be due to a backward movement of the lens, driven by a backward growth of the ciliary process, which might be a causative factor of myopia development.

Iodine is required for the production of the thyroid hormones essential for the growth and development of the brain. All forms of iodine deficiency (ID) affect the mental development of the child. Our study aims to assess the impact of ID on the intellectual development of Moroccan schoolchildren and to evaluate the effect of consumption of fortified milk on reducing ID. In a double-blind controlled trial conducted on schoolchildren, children were divided into two groups to receive fortified milk (30% of cover of RDI iodine) or nonfortified milk for 9 months. Urinary iodine was analyzed using the Sandell-Kolthoff reaction, a dynamic cognitive test using Raven's Standard Progressive Matrices to assess learning potential was performed at baseline and end line, and anthropometric assessment was done only at baseline. The study included schoolchildren who were severely iodine deficient. The prevalence of malnutrition was high in both groups; in this study, we found improvements in iodine status and in cognitive abilities among Moroccan schoolchildren. Our study showed that the consumption of fortified milk led to a clear improvement in iodine status and also appeared to have a favorable effect on the cognitive ability of Moroccan schoolchildren in a rural mountainous region.

Asthma is a chronic respiratory condition that affects over 300 million adults and children worldwide. It is characterised by wheeze, cough, chest tightness, and shortness of breath. Symptoms typically are intermittent and may worsen over a short time, leading to an exacerbation. Asthma exacerbations can be serious, leading to hospitalisation or even death in rare cases. Exacerbations may be treated by increasing an individual's usual medication and providing additional medication, such as oral steroids. Although antibiotics are sometimes included in the treatment regimen, bacterial infections are thought to be responsible for only a minority of exacerbations, and current guidance states that antibiotics should be reserved for cases in which clear signs, symptoms, or laboratory test results are suggestive of bacterial infection. To determine the efficacy and safety of antibiotics in the treatment of asthma exacerbations. We searched the Cochrane Airways Trials Register, which contains records compiled from multiple electronic and handsearched resources. We also searched trial registries and reference lists of primary studies. We conducted the most recent search in October 2017. We included studies comparing antibiotic therapy for asthma exacerbations in adults or children versus placebo or usual care not involving an antibiotic. We allowed studies including any type of antibiotic, any dose, and any duration, providing the aim was to treat the exacerbation. We included parallel studies of any duration conducted in any setting and planned to include cluster trials. We excluded cross-over trials. We included studies reported as full-text articles, those published as abstracts only, and unpublished data. At least two review authors screened the search results for eligible studies. We extracted outcome data, assessed risk of bias in duplicate, and resolved discrepancies by involving another review author. We analysed dichotomous data as odds ratios (ORs) or risk

Current methods for assessment of iodine intake in a population comprise measurements of urinary iodine concentration (UIC), thyroid volume by ultrasound (US-Tvol), and newborn TSH. Serum or dried blood spot thyroglobulin (DBS-Tg) is a new promising functional iodine status biomarker in children. In 1996, a new act on universal salt iodination was introduced in Croatia with 25 mg of potassium iodideper kg of salt. In 2002, Croatia finally reached iodine sufficiency. However, in 2009, median UIC in 101 schoolchildren from Zagreb, the capital of Croatia, was 288 µg/L, posing to be excessive. The aim of the study was to assess iodine intake in schoolchildren from the Zagreb area and to evaluate the value of DBS-Tg in schoolchildren as a new functional biomarker of iodine deficiency (and iodine excess). The study was part of a large international study in 6- to 12-year-old children supported by UNICEF, the Swiss Federal Institute of Technology (ETH Zurich) and the International Council for the Control of Iodine Deficiency Disorders (ICCIDD). According to international study results, the median cut-off Tg < 13 µg/L and/or < 3% Tg values > 40 µg/L indicate iodine sufficiency. The study included 159 schoolchildren (median age 9.1 ± 1.4 years) from Zagreb and a nearby small town of Jastrebarsko with measurements of UIC, US-Tvol, DBS-Tg, T4, TSH and iodine content in salt from households of schoolchildren (KI/kg of salt). Overall median UIC was 205 µg/L (range 1-505 µg/L). Thyroid volumes in schoolchildren measured by US were within the normal range according to reference values. Median DBS-Tg in schoolchildren was 12.1 µg/L with 3% of Tg values > 40 µg/L. High Tg values were in the UIC range < 50 µg/L and > 300 µg/L (U-shaped curve of Tg plotted against UIC). All children were euthyroid with geometric mean TSH 0.7 ± 0.3 mU/L and arithmetic mean T4 62 ± 12.5 nmol/L. The mean KI content per kg of salt was 24.9 ± 3.1 mg/kg (range 19-36 mg/kg). Study results

To quantify schoolchildren's exposure to ultraviolet erythemal radiation (UVER), personal dosimeters (VioSpor) were used to measure biologically effective ultraviolet (UV) radiation received in the course of their daily school activities. The study took place in two primary schools in Valencia (39°28'N), Spain, for several weeks from March 2008 until May 2009, with two age groups (6-8 years and 10-11 years) and involved about 47 schoolchildren. The median daily UV exposure values for all age groups and solar height intervals considered in the study ranged from 1.31 to 2.11 standard erythemal doses (SEDs). Individual UV exposure was analyzed as a function of age, gender and dosimeter position. Significant statistical differences were found between different age groups, with the younger age group receiving higher statistically significant UVER exposure. It was also found that boys received significantly higher UVER exposure than girls. It was also noted that shoulder dosimeters registered higher readings than wrist dosimeters. Exposure ratio (ER) is defined as the ratio between the personal dose on a selected anatomical site and the corresponding ambient dose on a horizontal plane. The median ER for all age groups and solar height intervals in the study range from 4.5% to 10.7%, with higher values at lower solar heights.
Fitness, Fatness and Active School Commuting among Liverpool Schoolchildren

This study investigated differences in health outcomes between active and passive school commuters, and examined associations between parent perceptions of the neighborhood environment and active school commuting (ASC). One hundred-ninety-four children (107 girls), aged 9–10 years from ten primary schools in Liverpool, England, participated in this cross-sectional study. Measures of stature, body mass, waist circumference and cardiorespiratory fitness (CRF) were taken. School commute mode (active/passive) was self-reported and parents completed the neighborhood environment walkability scale for youth. Fifty-three percent of children commuted to school actively. Schoolchildren who lived in more deprived neighborhoods perceived by parents as being highly connected, unaesthetic and having mixed land-use were more likely to commute to school actively (p < 0.05). These children were at greatest risk of being obese and aerobically unfit (p < 0.01). Our results suggest that deprivation may explain the counterintuitive relationship between obesity, CRF and ASC in Liverpool schoolchildren. These findings encourage researchers and policy makers to be equally mindful of the social determinants of health when advocating behavioral and environmental health interventions. Further research exploring contextual factors to ASC, and examining the concurrent effect of ASC and diet on weight status by deprivation is needed. PMID:28858268

To evaluate bacterial colonization and the airway inflammatory response, and its relationship to the frequency of exacerbation in patients with stable chronic obstructive pulmonary disease (COPD). Quantitative bacteriologic cultures, neutrophil elastase, myeloperoxidase (MPO), tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-8 were measured in bronchoalveoler lavage (BAL) in 39 patients with stable COPD [19 with frequent exacerbation (> or = 3/year), and 20 with infrequent] and in 18 healthy controls (10 smokers and 8 non-smokers). BAL revealed the microorganisms with potential pathogenicity above the established threshold (> or = 10(3)cfu/ml) in 68.4% of patients with frequent exacerbation, 55% of infrequent exacerbation, 40% of smokers and 12.5% of non-smokers controls (P=0.05). BAL MPO, IL-8 and TNF-alpha levels were found to be significantly higher in COPD as compared to controls (P=0.001). However, only IL-8 level was significantly higher in COPD patients with frequent exacerbation as compared to infrequent (P=0.001). Airway bacterial load correlated with levels of airway inflammation markers in COPD (P<0.05). The bacterial load and airway inflammation contributes to each other in stable COPD. However, there is a link only between interleukine (IL)-8 and frequent exacerbations. Clearly, the relationship between bacterial colonization, airway inflammation and frequent exacerbations is of major importance in understanding of the COPD pathogenesis.

The purpose of this study was to analyze the association of weight status and physical fitness with health-related quality of life (HRQoL) and to examine the independent association of body mass index (BMI), cardiorespiratory fitness (CRF) and musculoskeletal fitness (MF) with HRQoL in schoolchildren. Cross-sectional study of 1,158 schoolchildren, 8-11 years, from 20 schools in the Cuenca province, Spain. We measured weight, height, and physical fitness, measured by CRF (20-m shuttle run test) and MF index by summing the age-sex z scores of handgrip strength test/weight + standing broad jump test. Self-reported HRQoL was measured by KIDSCREEN-52 questionnaire. Normal weight boys scored better in physical well-being, mood and emotions, autonomy, and social support and peers dimensions than overweight/obese boys. The mean in self-perception dimensions was lower in obese girls compared to normal weight or overweight girls. Higher levels of CRF and MF were associated with better physical well-being in both genders. Multiple linear regression models showed that the influence of MF in boys and CRF in girls on HRQoL was greater than that of overweight. This is one of the first studies that assess the association of CRF and MF with HRQoL while controlling for BMI. CRF and MF are closely related to HRQoL, in particular to physical well-being. Improving fitness could be a strategy of particular interest for improving the HRQoL of schoolchildren.

Background There is a growing emphasis on the need to tackle inadequate human resources for health (HRH) as an essential part of strengthening health systems; but the focus is mostly on macro-level issues, such as training, recruitment, skill mix and distribution. Few attempts have been made to understand the capability of health workers, their motivation and other structural and organizational aspects of systems that influence workforce performance. We have examined literature on the roles of mid-level managers to help us understand how they might influence service delivery quality in Kenyan hospitals. In the Kenyan hospital settings, these are roles that head of departments who are also clinical or nursing service providers might play. Methods A computerized search strategy was run in Pub Med, Cochrane Library, Directory of Open Access Journals Social Science Research Network, Eldis, Google Scholar and Human Resources for Health web site databases using both free-text and MeSH terms from 1980 to 2011. In addition, citation searching from excluded and included articles was used and relevant unpublished literature systematically identified. Results and discussion A total of 23 articles were finally included in the review from over 7000 titles and abstracts initially identified. The most widely documented roles of mid-level managers were decision-making or problem-solving, strategist or negotiator and communicator. Others included being a therapist or motivator, goal setting or articulation and mentoring or coaching. In addition to these roles, we identified important personal attributes of a good manager, which included interpersonal skills, delegation and accountability, and honesty. The majority of studies included in the review concerned the roles that mid-level managers are expected to play in times of organizational change.

Specific bacterial species are implicated in the pathogenesis of exacerbations of chronic obstructive pulmonary disease (COPD). However, recent studies of clinically stable COPD patients have demonstrated a greater diversity of airway microbiota, whose role in acute exacerbations is unclear. In this study, temporal changes in the airway microbiome before, at the onset of, and after an acute exacerbation were examined in 60 sputum samples collected from subjects enrolled in a longitudinal study of bacterial infection in COPD. Microbiome composition and predicted functions were examined using 16S rRNA-based culture-independent profiling methods. Shifts in the abundance (≥2-fold, P < 0.05) of many taxa at exacerbation and after treatment were observed. Microbiota members that were increased at exacerbation were primarily of the Proteobacteria phylum, including nontypical COPD pathogens. Changes in the bacterial composition after treatment for an exacerbation differed significantly among the therapy regimens clinically prescribed (antibiotics only, oral corticosteroids only, or both). Treatment with antibiotics alone primarily decreased the abundance of Proteobacteria, with the prolonged suppression of some microbiota members being observed. In contrast, treatment with corticosteroids alone led to enrichment for Proteobacteria and members of other phyla. Predicted metagenomes of particular microbiota members involved in these compositional shifts indicated exacerbation-associated loss of functions involved in the synthesis of antimicrobial and anti-inflammatory products, alongside enrichment in functions related to pathogen-elicited inflammation. These trends reversed upon clinical recovery. Further larger studies will be necessary to determine whether specific compositional or functional changes detected in the airway microbiome could be useful indicators of exacerbation development or outcome.

In patients with COPD, self-management skills are important to reduce the impact of exacerbations. However, both detection and adequate response to exacerbations appear to be difficult for some patients. Little is known about the underlying process of exacerbation-related self-management. Therefore, the objective of this study was to identify and explain the underlying process of exacerbation-related self-management behavior. A qualitative study using semi-structured in-depth interviews was performed according to the grounded theory approach, following a cyclic process in which data collection and data analysis alternated. Fifteen patients (male n=8; age range 59-88 years) with mild to very severe COPD were recruited from primary and secondary care settings in the Netherlands, in 2015. Several patterns in exacerbation-related self-management behavior were identified, and a conceptual model describing factors influencing exacerbation-related self-management was developed. Acceptance, knowledge, experiences with exacerbations, perceived severity of symptoms and social support were important factors influencing exacerbation-related self-management. Specific factors influencing recognition of exacerbations were heterogeneity of exacerbations and habituation to symptoms. Feelings of fear, perceived influence on exacerbation course, patient beliefs, ambivalence toward treatment, trust in health care providers and self-empowerment were identified as specific factors influencing self-management actions. This study provided insight into factors influencing exacerbation-related self-management behavior in COPD patients. The conceptual model can be used as a framework for health care professionals providing self-management support. In the development of future self-management interventions, factors influencing the process of exacerbation-related self-management should be taken into account.

The symptomatology of Blastocystis cannot be attributed to any particular subtype, although can be related to a high Blastocystis infection load. One stool sample from each of 217 schoolchildren of Vale de Sol Paranaguá Bay (Paraná, Brazil) was collected. Three milliliters of each fixed stool sample were processed applying the formalin-ether concentration technique. After obtaining the overall prevalence of intestinal parasites, quantification was carried out in Blastocystis positive samples. A total of 75/217 (34.6%) children suffered from intestinal symptoms (abdominal pain and/or persistent diarrhea), of whom 41.3% (31/75) presented moderate/heavy Blastocystis load with a statistically significant risk to present intestinal symptoms (OR 0.039 [0.006-0.15]; p<0.001) Moreover, those symptomatic schoolchildren monoparasitized only by Blastocystis (10/75, 13.3%), and those polyparasitized by Blastocystis with other non-pathogenic species (15/75, 20%) with moderate/heavy loads, also entail a statistically significant risk of intestinal symptomatology, both in monoparasitism (12%, OR 0.10 [0.004-0.63]; p=0.021) and in polyparasitism with a non-pathogenic parasite (18.6%, OR 0.059 [0.002-0.35]; p=0.001). For the first time in Brazil, using data from schoolchildren of Paranaguá Bay, we demonstrated that moderate/ heavy loads of Blastocystis could be related to intestinal symptoms.

This study aims to reveal the secular trends in body mass index (BMI) and the prevalence of overweight and obesity among Polish schoolchildren between the years 1966-2012, during which intense socio-political changes took place. Four surveys were conducted in several districts of Poland looking at 69,746 schoolchildren aged 7-18. Significant increase in mean BMI as well as in the prevalence of overweight and obesity was observed. During this time the highest increase in both mean BMI and excess weight was observed between 1988 and 2012, i.e. after the political transformation, resulting in the improvement of living conditions. However, with respect to girls in late adolescence, between these years, the mean BMI as well as the prevalence of overweight were leveling off, while the percentage of boys with excess body fat in the same developmental category significantly increased in 2012. In the years 1966-1978 and 1978-1988 the pattern of changes in the prevalence of overweight and obesity reflected the social and economic circumstances, i.e. temporary economic improvements, or deepening political crises and food shortage. In conclusion, the weight status of schoolchildren strongly reflects socio-political changes that took place in Poland, as well as in most of the Central European countries in the last half century.

2016-05-01
The effects of chocolate on acne exacerbations have recently been reevaluated. For so many years, it was thought that it had no role in worsening acne. To investigate whether 99% dark chocolate, when consumed in regular daily amounts, would cause acne to worsen in acne-prone male subjects, twenty-five acne prone male subjects were asked to consume 25 g of 99% dark chocolate daily for 4 weeks. Assessments which included Leeds revised acne scores as well as lesion counts took place weekly. Food frequency questionnaire was used, and daily activities were recorded. Statistically significant changes of acne scores and numbers of comedones and inflammatory papules were detected as early as 2 weeks into the study. At 4 weeks, the changes remained statistically significant compared to baseline. Dark chocolate when consumed in normal amounts for 4 weeks can exacerbate acne in male subjects with acne-prone skin. © 2015 The International Society of Dermatology.

Treatment guidelines recommend the use of inhaled long-acting bronchodilators to alleviate symptoms and reduce the risk of exacerbations in patients with moderate-to-very-severe chronic obstructive pulmonary disease (COPD) but do not specify whether a long-acting anticholinergic drug or a β(2)-agonist is the preferred agent. We investigated whether the anticholinergic drug tiotropium is superior to the β(2)-agonist salmeterol in preventing exacerbations of COPD. In a 1-year, randomized, double-blind, double-dummy, parallel-group trial, we compared the effect of treatment with 18 μg of tiotropium once daily with that of 50 μg of salmeterol twice daily on the incidence of moderate or severe exacerbations in patients with moderate-to-very-severe COPD and a history of exacerbations in the preceding year. A total of 7376 patients were randomly assigned to and treated with tiotropium (3707 patients) or salmeterol (3669 patients). Tiotropium, as compared with salmeterol, increased the time to the first exacerbation (187 days vs. 145 days), with a 17% reduction in risk (hazard ratio, 0.83; 95% confidence interval [CI], 0.77 to 0.90; P<0.001). Tiotropium also increased the time to the first severe exacerbation (hazard ratio, 0.72; 95% CI, 0.61 to 0.85; P<0.001), reduced the annual number of moderate or severe exacerbations (0.64 vs. 0.72; rate ratio, 0.89; 95% CI, 0.83 to 0.96; P=0.002), and reduced the annual number of severe exacerbations (0.09 vs. 0.13; rate ratio, 0.73; 95% CI, 0.66 to 0.82; P<0.001). Overall, the incidence of serious adverse events and of adverse events leading to the discontinuation of treatment was similar in the two study groups. There were 64 deaths (1.7%) in the tiotropium group and 78 (2.1%) in the salmeterol group. These results show that, in patients with moderate-to-very-severe COPD, tiotropium is more effective than salmeterol in preventing exacerbations.

Zoonotic and vector-borne pathogens have comprised a significant component of emerging human infections in recent decades, and bats are increasingly recognized as reservoirs for many of these disease agents. To identify novel pathogens associated with bats, we screened tissues of bats collected in Kenya. Virus isolates were identified by next generation sequencing of viral nucleic acid preparations from the infected cell culture supernatant and characterized. Here we report the identification of Fikirini rhabdovirus, a novel rhabdovirus isolated from a bat, Hipposideros vittatus, captured along the Kenyan coast.

Childhood obesity is rising rapidly in many countries. Preadolescents appear to be at particularly high risk. This study estimated the prevalence of overweight and obesity in preadolescent schoolchildren in Galicia, Spain. The heights and weights of a random sample of 2305 Galician schoolchildren aged 10-12 years were measured using calibrated standardized scales and measures. Overweight and obesity were identified using the criteria of the International Obesity Task Force. The prevalences of obesity and overweight were respectively 9.2% and 31.0% among boys, 8.6% and 28.8% among girls and 8.9% and 29.9% overall. Taking boys and girls together, the combined prevalence of overweight and obesity fell significantly with increasing age. Overweight was more prevalent in rural than urban areas (30.7% vs. 28.4%), as also was obesity (9.8% vs. 7.2%). Our study evidences the emergence of the obesity epidemic among preadolescents in Galicia, especially in rural areas. Both overweight and obesity in this age group are more prevalent in Galicia than in other areas of Spain or most other Western nations.

This study aimed to understand the usage patterns and correlates of illicit drug use among schoolchildren in Colombo district, Sri Lanka. A cross-sectional study was carried out among grade 10 and 12 students using a self-administered questionnaire. From the 6000 students selected, 5353(89.22%) responded. Betel chewing with tobacco was seen in 28.48% males and 10.44% females. Substances such as Barbul, Madana Modaka, and cough syrups that are not established as illicit drugs were used as psychoactive substances. Ingredients of some of these compounds are not fully understood or regulated. Prevalence of cannabis use was 3.85% in males and 0.24% in females. Studying nonscience subjects for Advanced Level, doing sports, low academic performance, and peer smoking significantly increased the odds of using one or more substances (P < .05). Many types of illicit substances were used by schoolchildren. More strategies to prevent further aggravation of these behaviors are needed. Constituents of some compounds are not understood and need further evaluation. Recognized high-risk groups can be targets for preventive and cessation programs.
Television beer advertising and drinking knowledge, beliefs, and intentions among schoolchildren.
Grube, J W; Wallack, L
1994-02-01
The relationships between television beer advertising and drinking knowledge, beliefs, and intentions were investigated in a survey of schoolchildren. The research was guided by a theoretical model specifying that awareness of advertising, and not mere exposure, is necessary for it to have an effect on beliefs or behaviors. Participants were a random sample of 468 fifth- and sixth-grade schoolchildren from a northern California community. Data were collected in the home with a combination of self-administered questionnaires and structured interviews. Nonrecursive statistical modeling indicated that awareness of television beer advertising was related to more favorable beliefs about drinking, to greater knowledge of beer brands and slogans, and to increased intentions to drink as an adult. The effects of advertising awareness on knowledge, beliefs, and intentions were maintained when the reciprocal effects of beliefs, knowledge, and intentions on awareness were controlled. The findings suggest that alcohol advertising may predispose young people to drinking. As a result, efforts to prevent drinking and drinking problems among young people should give attention to countering the potential effects of alcohol advertising.

ABSTRACT Purpose To investigate near-vision posture in Chinese myopic schoolchildren and compare near-vision posture during different near-vision tasks (i.e., playing video games, reading, and writing). Methods The study investigated 120 myopic children (grades 1 through 6 and aged 6 to 13 years). An electromagnetic motion-tracking system was used for continuous measurements of the working distance and head declination of the subjects while they were playing video games or reading or writing at a desk. The reading and writing documents were adjusted by grade level (i.e., grades 1 to 2, 3 to 4, and 5 to 6). For analysis, the subjects were grouped in two refractive groups according to their median spherical equivalent refractive error (−1.50D). Results The myopic schoolchildren used close working distances for all tasks: 21.3 ± 5.2 cm (video games), 27.2 ± 6.4 cm (reading), and 24.9 ± 5.8 cm (writing). The mean head declinations were 63.5 ± 12.2 deg (video games), 37.1 ± 12.8 deg (reading), and 44.5 ± 14.1 deg (writing). Working distance decreased significantly across time for the reading and writing tasks (p < 0.001). Head declination increased significantly across time only for the reading task (p < 0.001). Grade level significantly influenced working distance, but the difference was not significant when working distance was adjusted by the subject’s size. No differences were observed within the refractive or the accommodative lag groups in terms of the posture data (p > 0.05). Working distance was negatively correlated with head declination (r = −0.53, p < 0.001). Conclusions Close working distances were observed for Chinese myopic schoolchildren. The attention dedicated to each task, the task difficulty, and the page/screen size may affect near working distance and head declination. Handheld video games were associated with the closest working distance, which may be a risk factor for myopia progression, according to previous studies. PMID:26107025

Objective: To analyze and compare the changes in physical fitness according to the nutritional status and gender of schoolchildren during a period of 30 years (1980-2010). Methods: Four cross-sectional evaluations were performed every 10 years in a period of 30 years from 1978 to 1980 (baseline), 1988-1990 (10 years), 1998-2000 (20 years) and 2008-2010 (30 years). The sample consisted of 1291 schoolchildren (188 in baseline, 307 in 10 years; 375 in 20 years; 421 in 30 years) of 10 and 11 years old. The variables assessed were: body weight (kg), height (cm), upper limb strength (ULS; kg), lower limb strength (LLS; cm), agility (seconds) and velocity (seconds). Schoolchildren were classified as normal weight and overweight according to World Health Organization reference of body mass index for age and gender. Comparisons among periods applied ANOVA followed by Bonferroni test, with a significance level set at of p<0.01. Variation between baseline and 30 years was assessed by the percentage delta. Seven different percentile values were presented for each variable. Results: In eutrophic boys and girls, mean values of ULS (−16.7%; −3.2%), agility (−1.5%; −1.6%) decreased significantly after 30 years (p<0.001). In the overweight boys and girls, only the average ULS (−15.5%; −12.5%) decreased significantly over time (p<0.001). After 30 years, the ULS percentile changed in boys. Conclusions: The decline in physical fitness was greater in schoolchildren with normal weight than in those with overweight. PMID:26298653

Background In Vietnam, initiatives have been started aimed at increasing the practice of handwashing with soap (HWWS) among primary schoolchildren. However, compliance remains low. Objective This study aims to investigate responses to a teacher-centred participatory HWWS intervention in a multi-ethnic population of primary schoolchildren in northern rural Vietnam. Design This study was implemented in two phases: a formative research project over 5 months (July–November 2008) and an action research project with a school-based HWWS intervention study in two rural communes during 5 months (May, September–December 2010). Based upon knowledge from the formative research in 2008, schoolteachers from four selected schools in the study communes actively participated in designing and implementing a HWWS intervention. Qualitative data was collected during the intervention to evaluate the responses and reaction to the intervention of teachers, children and parents. This included semi-structured interviews with children (15), and their parents (15), focus group discussions (FGDs) with schoolchildren (32) and school staff (20) and observations during 15 HWWS involving children. Results Observations and interview data from children demonstrated that children were visibly excited and pleased with HWWS sessions where teachers applied active teaching methods including rewards, games and HWWS demonstrations. All children, schoolteachers and parents also viewed the HWWS intervention as positive and feasible, irrespective of ethnicity, gender of schoolchildren and background of schoolteachers. However, some important barriers were indicated for sustaining and transferring the HWWS practice to the home setting including limited emphasis on hygiene in the standard curriculum of schools, low priority and lack of time given to practical teaching methods and lack of guidance and reminding HWWS on a regular basis at home, in particular by highland parents, who spend most of their time

Several authors mentioned the occurrence of articulation problems in the neurofibromatosis type 1 (NF1) population. However, few studies have undertaken a detailed analysis of the articulation skills of NF1 patients, especially in schoolchildren and adults. Therefore, the aim of the present study was to examine in depth the articulation skills of NF1 schoolchildren and adults, both phonetically and phonologically. Speech samples were collected from 43 Flemish NF1 patients (14 children and 29 adults), ranging in age between 7 and 53 years, using a standardized speech test in which all Flemish single speech sounds and most clusters occur in all their permissible syllable positions. Analyses concentrated on consonants only and included a phonetic inventory, a phonetic, and a phonological analysis. It was shown that phonetic inventories were incomplete in 16.28% (7/43) of participants, in which totally correct realizations of the sibilants /ʃ/ and/or /ʒ/ were missing. Phonetic analysis revealed that distortions were the predominant phonetic error type. Sigmatismus stridens, multiple ad- or interdentality, and, in children, rhotacismus non vibrans were frequently observed. From a phonological perspective, the most common error types were substitution and syllable structure errors. Particularly, devoicing, cluster simplification, and, in children, deletion of the final consonant of words were perceived. Further, it was demonstrated that significantly more men than women presented with an incomplete phonetic inventory, and that girls tended to display more articulation errors than boys. Additionally, children exhibited significantly more articulation errors than adults, suggesting that although the articulation skills of NF1 patients evolve positively with age, articulation problems do not resolve completely from childhood to adulthood. As such, the articulation errors made by NF1 adults may be regarded as residual articulation disorders. It can be concluded that the

Background Acute pulmonary exacerbations are associated with progressive lung function decline and increased mortality in cystic fibrosis (CF). The role of pulmonary vascular disease in pulmonary exacerbations is unknown. We investigated the association between pulmonary artery enlargement (PA:A>1), a marker of pulmonary vascular disease, and exacerbations. Methods We analyzed clinical, computed tomography (CT), and prospective exacerbation data in a derivation cohort of 74 adult CF patients, measuring the PA:A at the level of the PA bifurcation. We then replicated our findings in a validation cohort of 190 adult CF patients. Patients were separated into groups based on the presence or absence of a PA:A>1 and were followed for 1-year in the derivation cohort and 2-years in the validation cohort. The primary endpoint was developing ≥1 acute pulmonary exacerbation during follow-up. Linear and logistic regression models were used to determine associations between clinical factors, the PA:A ratio, and pulmonary exacerbations. We used Cox regression to determine time to first exacerbation in the validation cohort. Findings We found that PA:A>1 was present in n=37/74 (50%) of the derivation and n=89/190 (47%) of the validation cohort. In the derivation cohort, n=50/74 (68%) had ≥1 exacerbation at 1 year and n=133/190 (70%) in the validation cohort had ≥1 exacerbation after 2 years. PA:A>1 was associated with younger age in both cohorts and with elevated sweat chloride (100.5±10.9 versus 90.4±19.9mmol/L, difference between groups 10.1mmol/L [95%CI 2.5–17.7], P=0.017) in the derivation group. PA:A>1 was associated with exacerbations in the derivation (OR 3.49, 95%CI 1.18–10.3, P=0.023) and validation (OR 2.41, 95%CI 1.06–5.52, P=0.037) cohorts when adjusted for confounders. Time to first exacerbation was shorter in PA:A>1 versus PA:A<1 [HR 1.66 (95%CI 1.18–2.34), P=0.004] in unadjusted analysis, but not when adjusted for sex, BMI, prior exacerbation

The aim of this article was to evaluate associations between body mass index (BMI) and use of and distance from subjects homes of elements of the food and physical activity environments and use of social assistance environment, in schoolchildren from 7 to 14 years living in Florianópolis (South Brazil), stratified by monthly family income. A cross-sectional study was conducted with a probabilistic sample of 2152 schoolchildren. Univariate and multivariate linear regression analyses were conducted to test for associations between BMI and the use of and distance from supermarkets, bakeries and farmers' markets; use of and distance from parks/playgrounds and football pitches; and use of health centers, Reference Centers for Social Assistance, instructional facilities, residents associations, religious groups and a Brazilian program for cash transfer. Overweight and obesity rates were 21.5 and 12.7%, respectively. Among schoolchildren from low-income families, living more than 11 min' walk from parks/playgrounds was associated with higher BMI (β = 0.53; 95% CI = 0.33-0.73). In the high-income strata, a longer distance from home to football pitches was associated with lower BMI (β = -0.49; 95% CI = -0.69; -0.29). Neither food nor social assistance environments were associated with BMI of schoolchildren, even when analyzed by income strata.

The genetic diversity of C. albicans oral isolates from 75 healthy schoolchildren from eight schools located in different geographic areas of Piracicaba city, São Paulo state, Brazil, was established using isoenzymes marker (Multilocus Enzyme Electrophoresis – MLEE) and cluster analysis. Patterns of monoclonal and polyclonal oral colonization by C. albicans within and between groups of schoolchildren were identified. However, significant divergence between the observed and the expected genotypic frequencies (Hardy-Weinberg equilibrium test) was not detected in the geographically adjacent groups, suggesting the hypothesis that populations of healthy schoolchildren do not correspond to the selection factor (differential survival) of strains. Two highly polymorphic and distantly genetically related taxa (A and B) were identified within the total population of yeasts, each contained subgroups (A1, A2, A3, A4, B1 and B2) and clusters of moderately related strains (from I to X), suggesting the existence of strains restricted or not to certain groups of geographically limited, healthy students. However, the coexistence of identical strains in healthy schoolchildren from the same school (geographically related) reinforces the hypothesis of oral transmission, where the sources of propagation could be explored. Furthermore, this could also be used in current and retrospective analyses of C. albicans isolated from immunocompetent and immunocompromised people, in order to detect commensal or potentially pathogenic yeast groups, predominantly in candidiasis, and in the development of strategies to prevent transmission or human propagation.

Hypertension and obesity in children are increasing concerns worldwide. A cross-sectional study of hypertension in relation to overweight/obesity was conducted in 2009 among schoolchildren aged 6-16 years in Aden, Yemen. Using multistage stratified random sampling 1885 children were classified into wasted, normal weight, overweight and obese according to body mass index. The prevalence of wasting was 10.1%, normal weight 69.2%, overweight 12.7% and obesity 8.0%. The rate of high blood pressure (World Health Organization criteria) was 8.2% for prehypertension and 2.4% for hypertension and was significantly related to the presence of overweight or obesity. Child's body mass index combined with age was a predictor for systolic and diastolic blood pressure. The study provides further evidence that overweight/obesity is associated with hypertension in these schoolchildren.

Background Evaluation of eating habits and physical activity is very important for health interventions. Our aim in this study was to assess the characteristics of eating and physical activity of 6–7th grade schoolchildren in the city of Vilnius, Lithuania, as well as the association between dietary habits and physical activity. Methods The study was conducted within the project “Education of healthy diets and physical activity in schools”. The sample consisted of 1008 schoolchildren from 22 schools in the city of Vilnius, and was based on empirical methods, including a questionnaire poll and comparative analysis. Statistical software Stata v.12.1 (Stata corp LP) was used to analyze the data. Results Our study showed that less than half (37.1%) of study participants had physically active leisure time. Boys were significantly more physically active than girls. More than half (61.4%) of children ate breakfast every day. Girls were more likely to eat vegetables and sweets. Schoolchildren who ate vegetables and dairy products as well as those who got enough information about physical activity and spoke about it with their family members were more physically active. Conclusions The results of the study confirmed that schoolchildren were not sufficiently physically active. It was found that low physical activity is related to dietary and other factors, such as lack of information about physical activity and its benefits. PMID:28352688

Identifying caries risk factors is an important measure which contributes to best understanding of the cariogenic profile of the patient. The Cariogram® software provides this analysis, and protocols simplifying the method were suggested. Objectives The aim of this study was to determine whether a newly developed Caries Risk Assessment (CRA) form based on the Cariogram® software could classify schoolchildren according to their caries risk and to evaluate relationships between caries risk and the variables in the form. Material and Methods 150 schoolchildren aged 5 to 7 years old were included in this survey. Caries prevalence was obtained according to International Caries Detection and Assessment System (ICDAS) II. Information for filling in the form based on Cariogram® was collected clinically and from questionnaires sent to parents. Linear regression and a forward stepwise multiple regression model were applied to correlate the variables included in the form with the caries risk. Results Caries prevalence, in primary dentition, including enamel and dentine carious lesions was 98.6%, and 77.3% when only dentine lesions were considered. Eighty-six percent of the children were classified as at moderate caries risk. The forward stepwise multiple regression model result was significant (R2=0.904; p<0.00001), showing that the most significant factors influencing caries risk were caries experience, oral hygiene, frequency of food consumption, sugar consumption and fluoride sources. Conclusion The use of the form based on the Cariogram® software enabled classification of the schoolchildren at low, moderate and high caries risk. Caries experience, oral hygiene, frequency of food consumption, sugar consumption and fluoride sources are the variables that were shown to be highly correlated with caries risk. PMID:25466473

Normative reference values for handgrip strength in Colombian schoolchildren: the FUPRECOL study. J Strength Cond Res 31(1): 217-226, 2017-The primary aim of this study was to generate normative handgrip (HG) strength data for 10 to 17.9 year olds. The secondary aim was to determine the relative proportion of Colombian children and adolescents that fall into established Health Benefit Zones (HBZ). This cross-sectional study enrolled 7,268 schoolchildren (boys n = 3,129 and girls n = 4,139, age 12.7 [2.4] years). Handgrip was measured using a hand dynamometer with an adjustable grip. Five HBZs (Needs Improvement, Fair, Good, Very Good, and Excellent) have been established that correspond to combined HG. Centile smoothed curves, percentile, and tables for the third, 10th, 25th, 50th, 75th, 90th, and 97th percentile were calculated using Cole's LMS method. Handgrip peaked in the sample at 22.2 (8.9) kg in boys and 18.5 (5.5) kg in girls. The increase in HG was greater for boys than for girls, but the peak HG was lower in girls than in boys. The HBZ data indicated that a higher overall percentage of boys than girls at each age group fell into the "Needs Improvement" zone, with differences particularly pronounced during adolescence. Our results provide, for the first time, sex- and age-specific HG reference standards for Colombian schoolchildren aged 9-17.9 years.

Background: Green spaces have been associated with improved mental health in children; however, available epidemiological evidence on their impact on child behavioral development is scarce. Objectives: We investigated the impact of contact with green spaces and blue spaces (beaches) on indicators of behavioral development and symptoms of attention deficit/hyperactivity disorder (ADHD) in schoolchildren. Methods: This study was based on a sample of 2,111 schoolchildren (7–10 years of age) from 36 schools in Barcelona in 2012. We obtained data on time spent in green spaces and beaches and Strengths and Difficulties Questionnaires (SDQ) from parents, and ADHD/DSM-IV questionnaires from teachers. Surrounding greenness was abstracted as the average Normalized Difference Vegetation Index (NDVI) in buffers of 100 m, 250 m, and 500 m around each home address. Proximity to green spaces was defined as living within 300 m of a major green space (≥ 0.05 km2). We applied quasi-Poisson mixed-effects models (with school random effect) to separately estimate associations between indicators of contact with green spaces and SDQ and ADHD total and subscale scores. Results: We generally estimated beneficial associations between behavioral indicators and longer time spent in green spaces and beaches, and with residential surrounding greenness. Specifically, we found statistically significant inverse associations between green space playing time and SDQ total difficulties, emotional symptoms, and peer relationship problems; between residential surrounding greenness and SDQ total difficulties and hyperactivity/inattention and ADHD/DSM-IV total and inattention scores; and between annual beach attendance and SDQ total difficulties, peer relationship problems, and prosocial behavior. For proximity to major green spaces, the results were not conclusive. Conclusion: Our findings support beneficial impacts of contact with green and blue spaces on behavioral development in schoolchildren

As the results from epidemiological studies about the impact of outdoor air pollution on asthma in children are heterogeneous, our objective was to investigate the association between asthma exacerbation in children and exposure to air pollutants. A database of 1 264 585 paediatric visits during the 2010-2015 period to the emergency rooms from 20 emergency departments (EDs) of 'Assistance Publique Hôpitaux de Paris (APHP)', the largest hospital group in Europe, was used. A total of 47 107 visits were classified as asthma exacerbations. Concentration of air pollutants (nitrogen dioxide, ozone, fine particulate matter (PM) with an aerodynamic diameter smaller than 10 µm (PM 10 ) and 2.5 µm (PM 2.5 )), as well as meteorological data, evolution of respiratory syncytial virus infection and pollen exposition, were collected on an hourly or daily basis for the same period using institutional databases. To assess the association between air pollution and asthma, mixed-effects quasi-Poisson regression modelling was performed. The only compound independently associated with ED visits for asthma was PM 2.5 (P<10 -4 ). The association between asthma exacerbation and PM 2.5 was not linear, and a sigmoid function described the relationshipsatisfactorily. PM 2.5 concentration, which gives half the maximum effect, was estimated at 13.5 µg/m 3 . We found an association between daily asthma exacerbation in paediatric visits to the ED and fine particulate air pollutants. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Asthma exacerbations in school-aged children peak in autumn, shortly after children return to school following the summer holiday. This might reflect a combination of risk factors, including poor treatment adherence, increased allergen and viral exposure, and altered immune tolerance. Since this peak is predictable, interventions targeting modifiable risk factors might reduce exacerbation-associated morbidity and strain upon health resources. The peak occurs in September in the Northern Hemisphere and in February in the Southern Hemisphere. To assess the effects of pharmacotherapy and behavioural interventions enacted in anticipation of school return during autumn that are designed to reduce asthma exacerbations in children during this period. We searched the Cochrane Airways Group Trials Register, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform, reference lists of primary studies and existing reviews, and manufacturers' trial registries (Merck, Novartis and Ono Parmaceuticals). We searched databases from their inception to 1 December 2017, and imposed no restriction on language of publication. We included all randomised controlled trials comparing interventions aimed specifically at reducing autumn exacerbations with usual care, (no systematic change in management in preparation for school return). We included studies providing data on children aged 18 years or younger. We used standard methodological procedures expected by Cochrane. Two review authors independently screened records identified by the search and then extracted data and assessed bias for trials meeting the inclusion criteria. A third review author checked for accuracy and mediated consensus on disagreements. The primary outcome was proportion of children experiencing one or more asthma exacerbations requiring hospitalisation or oral corticosteroids during the autumn period. Our searches returned 546 trials, of which five met our inclusion criteria

Lung volume reduction surgery (LVRS) has been demonstrated to provide a functional and mortality benefit to a select group of subjects with chronic obstructive pulmonary disease (COPD). The effect of LVRS on COPD exacerbations has not been as extensively studied, and whether improvement in postoperative lung function alters the risk of disease exacerbations is not known. To examine the effect, and mechanism of potential benefit, of LVRS on COPD exacerbations by comparing the medical and surgical cohorts of the National Emphysema Treatment Trial (NETT). A COPD exacerbation was defined using Centers for Medicare and Medicaid Services data and International Classification of Diseases, Ninth Revision, discharge diagnosis. There was no difference in exacerbation rate or time to first exacerbation between the medical and surgical cohorts during the year before study randomization (P = 0.58 and 0.85, respectively). Postrandomization, the surgical cohort experienced an approximate 30% reduction in exacerbation frequency (P = 0.0005). This effect was greatest in those subjects with the largest postoperative improvement in FEV(1) (P = 0.04) when controlling for changes in other spirometric measures of lung function, lung capacities, and room air arterial blood gas tensions. Finally, LVRS increased the time to first exacerbation in both those subjects with and those without a prior history of exacerbations (P = 0.0002 and P < 0.0001, respectively). LVRS reduces the frequency of COPD exacerbations and increases the time to first exacerbation. One explanation for this benefit may be the postoperative improvement in lung function.

Chronic obstructive pulmonary disease (COPD) exacerbations account for a substantial proportion of COPD-related costs. To describe COPD exacerbation patterns and assess the association between exacerbation frequency and health care resource utilization (HCRU) and costs in patients with COPD in a Medicare population. A retrospective cohort study utilizing data from a large US national health plan was conducted including patients with a COPD diagnosis during January 1, 2007 to December 31, 2012, aged 40-89 years and continuously enrolled in a Medicare Advantage Prescription Drug plan. Exacerbation frequency, HCRU, and costs were assessed during a 24-month period following the first COPD diagnosis (follow-up period). Four cohorts were created based on exacerbation frequency (zero, one, two, and ≥three). HCRU and costs were compared among the four cohorts using chi-square tests and analysis of variance, respectively. A trend analysis was performed to assess the association between exacerbation frequency and costs using generalized linear models. Of the included 52,459 patients, 44.3% had at least one exacerbation; 26.3%, 9.5%, and 8.5% had one, two, and ≥three exacerbations in the 24-month follow-up period, respectively. HCRU was significantly different among cohorts (all P<0.001). In patients with zero, one, two, and ≥three exacerbations, the percentages of patients experiencing all-cause hospitalizations were 49.7%, 66.4%, 69.7%, and 77.8%, respectively, and those experiencing COPD-related hospitalizations were 0%, 40.4%, 48.1%, and 60.5%, respectively. Mean all-cause total costs (medical and pharmacy) were more than twofold greater in patients with ≥three exacerbations compared to patients with zero exacerbations ($27,133 vs $56,033; P<0.001), whereas a greater than sevenfold difference was observed in mean COPD-related total costs ($1,605 vs $12,257; P<0.001). COPD patients frequently experience exacerbations. Increasing exacerbation frequency is associated

A population-representative lot quality assurance sampling (LQAS) survey was conducted in 2009 to determine the prevalence of intestinal helminth infections among schoolchildren across Osh oblast, Kyrgyzstan. The diagnostic approach consisted of duplicate Kato-Katz thick smears from a single stool sample and an adhesive tape test. A questionnaire was administered to identify risk factors for infections. A total of 1262 schoolchildren aged 6-15 years were recruited; 41% of them harboured at least one of the eight identified helminth species. The two most prevalent helminths were Ascaris lumbricoides (23.1%) and Enterobius vermicularis (19.3%). Lower prevalences were found for Hymenolepis nana (4.4%), Fasciola hepatica (1.9%) and Dicrocoelium dendriticum (1.8%). Washing raw vegetables was a protective factor with regard to A. lumbricoides infection (odds ratio (OR)=0.69, p=0.022); tap water was borderline protective (OR=0.56, p=0.057). Children of the richest families were at a lower risk of E. vermicularis infection than the poorest ones (OR=0.41, p=0.011). Sharing the bed with more than one person was a risk factor for E. vermicularis infection (OR=2.0, p=0.002). The results call for targeted interventions against intestinal helminths in Osh oblast. In a first stage, annual deworming of schoolchildren and other high-risk groups with albendazole or mebendazole should be implemented, and reliable diagnosis and additional anthelminthic drugs should be made available. Subsequently, transmission control including locally-adapted health education, improved water supply and adequate sanitation should become the central features. Copyright © 2010 Elsevier B.V.

Adverse childhood experiences are a critical feature of lifelong health. No research assesses whether childhood adversities predict HIV-testing behaviors, and little research analyzes childhood adversities and later life HIV status in sub-Saharan Africa. We use regression models with cross-sectional data from a representative sample (n = 1974) to analyze whether adverse childhood experiences, separately or as cumulative exposures, predict reports of later life HIV testing and testing HIV+ among semi-rural Kenyan women and their partners. No significant correlation was observed between thirteen cumulative childhood adversities and reporting prior HIV testing for respondent or partner. Separately, childhood sexual abuse and emotional neglect predicted lower odds of reporting having previously been tested for HIV. Witnessing household violence during one's childhood predicted significantly higher odds of reporting HIV+. Sexual abuse predicted higher odds of reporting a partner tested HIV+. Preventing sexual abuse and household violence may improve HIV testing and test outcomes among Kenyan women. More research is required to understand pathways between adverse childhood experiences and partner selection within Kenya and sub-Saharan Africa, and data presented here suggest understanding pathways may help improve HIV outcomes. © The Author 2016.

To assess the association between weight status and dental caries among 12-year-old Brazilian schoolchildren. This cross-sectional study was carried out in Porto Alegre using a multistage probability sampling strategy to draw a representative sample of schoolchildren attending public and private schools. Data on demographics, socioeconomic status, oral hygiene habits, anthropometrics, and dental caries were collected. Overweight and obesity were defined according to WHO categories for BMI (body mass index)-for-age Z-scores. Survey Poisson regression models were used to assess the association between weight status and dental caries. Estimates were adjusted for gender, socioeconomic status, and brushing frequency. Prevalence ratios (PR), rate ratios (RR) and 95% confidence intervals (95% CI) were reported. One thousand five hundred and twenty-eight of 1837 eligible schoolchildren were examined. Prevalence of overweight and obesity were 22.15% (95% CI = 20.59-23.72) and 13.61% (95% CI = 11.44-15.78), respectively. Caries experience was observed in 55.23% (95% CI = 45.26-65.19) of children. Schoolchildren presented, on average, 1.39 (95% CI = 1.07-1.71) decayed, missing or filled teeth. No significant differences in caries experience or extent were observed among BMI groups. After adjusting for important cofactors, weight status was not associated with caries prevalence (overweight, PR = 0.99; 95% CI = 0.89-1.10; obese, PR = 1.00; 95% CI = 0.87-1.16) or caries extent (overweight, RR = 0.91; 95% CI = 0.74-1.12; obese, RR = 0.86; 95% CI = 0.72-1.04). Our findings indicate that overweight and obese adolescents should not be regarded as at higher risk of dental caries in this population. © 2012 John Wiley & Sons A/S.

Acute pulmonary exacerbations are central events in the lives of individuals with cystic fibrosis (CF). Pulmonary exacerbations lead to impaired lung function, worse quality of life, and shorter survival. We hypothesized that aggressive early treatment of acute pulmonary exacerbation may improve clinical outcomes. Describe the rationale of an ongoing trial designed to determine the efficacy of home monitoring of both lung function measurements and symptoms for early detection and subsequent early treatment of acute CF pulmonary exacerbations. A randomized, non-blinded, multi-center trial in 320 individuals with CF aged 14 years and older. The study compares usual care to a twice a week assessment of home spirometry and CF respiratory symptoms using an electronic device with data transmission to the research personnel to identify and trigger early treatment of CF pulmonary exacerbation. Participants will be enrolled in the study for 12 months. The primary endpoint is change in FEV1 (L) from baseline to 12 months determined by a linear mixed effects model incorporating all quarterly FEV1 measurements. Secondary endpoints include time to first acute protocol-defined pulmonary exacerbation, number of acute pulmonary exacerbations, number of hospitalization days for acute pulmonary exacerbation, time from the end of acute pulmonary exacerbation to onset of subsequent pulmonary exacerbation, change in health related quality of life, change in treatment burden, change in CF respiratory symptoms, and adherence to the study protocol. This study is a first step in establishing alternative approaches to the care of CF pulmonary exacerbations. We hypothesize that early treatment of pulmonary exacerbations has the potential to slow lung function decline, reduce respiratory symptoms and improve the quality of life for individuals with CF. © 2013.

To know the infection status of helminths in primary schoolchildren of southern parts of Vietnam, we performed an epidemiological study in Krong Pac district, Dak Lak Province, Vietnam. A total of 1,206 stool specimens were collected from ethnic Ede schoolchildren in 4 primary schools in 2015 and examined by the Kato-Katz technique. In addition, stool cultures were done by the Harada-Mori method to obtain hookworm larvae and then to clarify the species of hookworms infected. The results showed that the helminth infection rate was 25.0%, including 2.0% Ascaris lumbricoides, 0.33% Trichuris trichiura, and 22.8% hookworm infections. The average intensity of infection was 102.0 eggs per gram of feces (EPG) for Ascaris, 36.0 EPG for Trichuris, and 218.0 EPG for hookworms. ITS1 gene sequences of the hookworm larvae were identical with those of Necator americanus (100% homology) reported in GenBank. It has been confirmed in this study that the hookworm, N. americanus, is a dominant helminth species infected in primary schoolchildren of a southern part of Vietnam. Public health attention is needed for control of hookworm infections among schoolchildren in surveyed areas of Vietnam.

To analyze and compare the changes in physical fitness according to the nutritional status and gender of schoolchildren during a period of 30 years (1980-2010). Four cross-sectional evaluations were performed every 10 years in a period of 30 years from 1978 to 1980 (baseline), 1988-1990 (10 years), 1998-2000 (20 years) and 2008-2010 (30 years). The sample consisted of 1,291 schoolchildren (188 in baseline, 307 in 10 years; 375 in 20 years; 421 in 30 years) of 10 and 11 years old. The variables assessed were: body weight (kg), height (cm), upper limb strength (ULS; kg), lower limb strength (LLS; cm), agility (seconds) and velocity (seconds). Schoolchildren were classified as normal weight and overweight according to World Health Organization reference of body mass index for age and gender. Comparisons among periods applied ANOVA folled by Bonferroni test, with a significance level set at of p<0.01. Variation between baseline and 30 years was assessed by the percentage delta. Seven different percentile values were presented for each variable. In eutrophic boys and girls, mean values of ULS (-16.7%; -3.2%), agility (-1.5%; -1.6%) decreased significantly after 30 years (p<0,001). In the overweight boys and girls, only the average ULS (-15.5%; -12.5%) decreased significantly over time (p<0,001). After 30 years, the ULS percentile changed in boys. the decline in physical fitness was greater in schoolchildren with normal weight than in those with overweight.

The traditional psychological approach of studying aggression among schoolchildren in terms of individual differences in aggression and in victimization has been valuable in identifying prevalence rates, risk, and consequences of involvement in aggression. However, it is argued that a focus on aggressor-victim relationships is warranted based on both conceptual and empirical grounds. Such a shift in focus requires modification and integration of existing theories of aggression, and this paper integrates social cognitive theory and interdependence theory to suggest a new, interdependent social cognitive theory of aggression. Specifically, this paper identifies points of overlap and different foci between these theories, and it illustrates their integration through a proposed model of the emergence of aggressor-victim interactions and relationships. The paper concludes that expanding consideration to include aggressor-victim relationships among schoolchildren offers considerable theoretical, empirical, and intervention opportunities.

Chronic Obstructive Pulmonary Disease is the third leading cause of death in the US, and is associated with periodic exacerbations, which account for the largest proportion of health care utilization, and lead to significant morbidity, mortality, and worsening lung function. A subset of patients with COPD have frequent exacerbations, occurring 2 or more times per year. Despite many interventions to reduce COPD exacerbations, there is a significant lack of knowledge in regards to their mechanisms and predisposing factors. We describe here an important observation that defines antibody deficiency as a potential risk factor for frequent COPD exacerbations. We report a case series of patients who have frequent COPD exacerbations, and who were found to have an underlying primary antibody deficiency syndrome. We also report on the outcome of COPD exacerbations following treatment in a subset with of these patients with antibody deficiency. We identified patients with COPD who had 2 or more moderate to severe exacerbations per year; immune evaluation including serum immunoglobulin levels and pneumococcal IgG titers was performed. Patients diagnosed with an antibody deficiency syndrome were treated with either immunoglobulin replacement therapy or prophylactic antibiotics, and their COPD exacerbations were monitored over time. A total of 42 patients were identified who had 2 or more moderate to severe COPD exacerbations per year. Twenty-nine patients had an underlying antibody deficiency syndrome: common variable immunodeficiency (8), specific antibody deficiency (20), and selective IgA deficiency (1). Twenty-two patients had a follow-up for at least 1 year after treatment of their antibody deficiency, which resulted in a significant reduction of COPD exacerbations, courses of oral corticosteroid use and cumulative annual dose of oral corticosteroid use, rescue antibiotic use, and hospitalizations for COPD exacerbations. This case series identifies antibody deficiency as a

We identified patients with COPD who had 2 or more moderate to severe exacerbations per year; immune evaluation including serum immunoglobulin levels and pneumococcal IgG titers was performed. Patients diagnosed with an antibody deficiency syndrome were treated with either immunoglobulin replacement therapy or prophylactic antibiotics, and their COPD exacerbations were monitored over time. A total of 42 patients were identified who had 2 or more moderate to severe COPD exacerbations per year. Twenty-nine patients had an underlying antibody deficiency syndrome: common variable immunodeficiency (8), specific antibody deficiency (20), and selective IgA deficiency (1). Twenty-two patients had a follow-up for at least 1 year after treatment of their antibody deficiency, which resulted in a significant reduction of COPD exacerbations, courses of oral corticosteroid use and cumulative annual dose of oral corticosteroid use, rescue antibiotic use, and hospitalizations for COPD exacerbations. This case series identifies antibody deficiency as a

Bronchiectasis exacerbations are critical events characterized by worsened symptoms and signs (ie, cough frequency, sputum volume, malaise). Our goal was to examine variations in airway and systemic inflammation, spirometry, and quality of life during steady state, bronchiectasis exacerbations, and convalescence (1 week following a 2-week antibiotic treatment) to determine whether potentially pathogenic microorganisms, including Pseudomonas aeruginosa, were associated with poorer conditions during bronchiectasis exacerbations. Peripheral blood and sputum were sampled to detect inflammatory mediators and bacterial densities. Spirometry and quality of life (St George Respiratory Questionnaire [SGRQ]) were assessed during the 3 stages. Forty-eight subjects with bronchiectasis (43.2 ± 14.2 y of age) were analyzed. No notable differences in species and density of potentially pathogenic microorganisms were found during bronchiectasis exacerbations. Except for CXCL8 and tumor necrosis factor alpha (TNF-α), serum inflammation was heightened during bronchiectasis exacerbations and recovered during convalescence. Even though sputum TNF-α was markedly higher during bronchiectasis exacerbations and remained heightened during convalescence, the variations in miscellaneous sputum markers were unremarkable. Bronchiectasis exacerbations were associated with notably higher SGRQ symptom and total scores, which recovered during convalescence. FVC, FEV1, and maximum mid-expiratory flow worsened during bronchiectasis exacerbations (median change from baseline of -2.2%, -0.8%, and -1.3%) and recovered during convalescence (median change from baseline of 0.6%, 0.7%, and -0.7%). Compared with no bacterial isolation, potentially pathogenic microorganism or P. aeruginosa isolation at baseline did not result in poorer clinical condition during bronchiectasis exacerbations. Bronchiectasis exacerbations are characterized by heightened inflammatory responses and poorer quality of life and

Despite the increasing awareness of their pathogenesis and clinical consequences, research on and clinical management of acute exacerbations of chronic obstructive lung disease (AECOPDs) have been hindered by the lack of a consistent and reliable definition. Symptom-based definitions of exacerbations are sensitive to events and account for unreported exacerbations. Event (healthcare utilization)-based definitions are somewhat more definitive but miss unreported events. Objective quantification of symptoms in AECOPD is now possible with the development of the Exacerbations of Chronic Obstructive Pulmonary Disease Tool (EXACT-PRO), a patient-reported outcome (PRO) measure. Several studies have revealed that unreported AECOPDs are more frequent than reported events and are associated with long-term adverse consequences. New antibiotic development for AECOPD has been hampered by the lack of validated measures for resolution of exacerbations. As a result of these observations, a unique collaborative effort between academia, industry and regulatory agencies resulted in the development of the EXACT-PRO. It consists of 14 questions that generate a score between 0 and 100, and it has been shown to have excellent reliability and validity. In the absence of a reliable biomarker, the definition and measurement of exacerbations has been subjective and imprecise. PRO measures such as EXACT can provide much needed objectivity in assessing symptom-defined exacerbations, which may translate into a uniform outcome measure in clinical trials. With further development and validation, it may have a role in clinical practice in the earlier detection of exacerbations, stratification of an exacerbation severity and the assessment of clinical response to treatment.

Severe exacerbations of COPD, ie, those leading to hospitalization, have profound clinical implications for patients and significant economic consequences for society. The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system. This review identified risk factors that contribute to the development of severe exacerbations, treatment options (bronchodilators, antibiotics, corticosteroids [CSs], oxygen therapy, and ventilator support) to manage severe exacerbations, and strategies to prevent readmission to hospital. Risk factors that are amenable to change have been highlighted. A number of bronchodilators have demonstrated successful reduction in risk of severe exacerbations, including long-acting muscarinic antagonist or long-acting β2-agonist mono- or combination therapies, in addition to vaccination, mucolytic and antibiotic therapy, and nonpharmacological interventions, such as pulmonary rehabilitation. Recognition of the importance of severe exacerbations is an essential step in improving outcomes for patients with COPD. Evidence-based approaches to prevent and manage severe exacerbations should be implemented as part of targeted strategies for disease management. PMID:29062228

To assess the development of language regarding the ability to recognize and interpret lexical ambiguity in low-birth-weight schoolchildren enrolled at the school system in the municipality of Embu das Artes, Sao Paulo state, compared with that of schoolchildren with normal birth weight. A case-control, retrospective, cross-sectional study conducted with 378 schoolchildren, both genders, aged 5 to 9.9 years, from the municipal schools of Embu das Artes. Study Group (SG) comprising 210 schoolchildren with birth weight < 2500 g. Control Group (CG) composed of 168 school children with birth weight ≥ 2500 g. Participants of both groups were compared with respect to the skills of recognition and verbal interpretation of sentences containing lexical ambiguity using the Test of Language Competence. Variables of interest: Age and gender of children; age and schooling of mothers. Statistical analysis: Descriptive analysis to characterize the sample and score per group; Student's t test for comparison between the total scores of each skill/subtest; Chi-square test to compare items within each subtest; multiple regression analysis for the intervening variables. Participants of the SG presented lower scores for ambiguous sentences compared with those of participants of the CG. Multiple regression analysis showed that child's current age was a predictor for all metalinguistic skills regarding interpretation of ambiguities in both groups. Participants of the SG presented lower specific and total scores than those of participants of the CG for ambiguity skills. The child's current age factor positively influenced the ambiguity skills in both groups.

Are individual differences in numerical performance sustained by variations in gray matter volume in schoolchildren? To our knowledge, this challenging question for neuroeducation has not yet been investigated in typical development. We used the Voxel-Based Morphometry method to search for possible structural brain differences between two groups of 10-year-old schoolchildren (N = 22) whose performance differed only in numerical transcoding between analog and symbolic systems. The results indicated that children with low numerical proficiency have less gray matter volume in the parietal (particularly in the left intraparietal sulcus and the bilateral angular gyri) and occipito-temporal areas. All the identified regions have previously been shown to be functionally involved in transcoding between analog and symbolic numerical systems. Our data contribute to a better understanding of the intertwined relationships between mathematics learning and brain structure in healthy schoolchildren.

Physical activity and low-back pain in schoolchildren.
Skoffer, Birgit; Foldspang, Anders
2008-03-01
Design of the experiment is to study the cross-sectional sample with retrospective information. The objective is to identify the types of physical activity associated with the decreased occurrence of low-back pain (LBP) in schoolchildren. Physical activity may be hypothesized to possess a potential for LBP prevention. The possible connection between LBP and specific sports activities is however sparsely documented. A total of 546, 15- to 16-year-old schoolchildren filled a questionnaire on current physical activities and LBP occurrence and severity. In multiple logistic regressions, the association of LBP with exposure variables was corrected for body height and weight (data from school health service files) and for anthropometric and school furniture parameters. More than half of the children reported pain or discomfort in the low-back region during the preceding 3 months, and 1/4 experienced a decreased functioning or need of care because of LBP. LBP correlated with physical inactivity, e.g. time spent on homework and hours watching TV or video, and with a series of sports activities, e.g. jogging, handball playing and gymnastics. Among sports activities, only swimming and the number of hours per week participating in soccer were associated with a decreased LBP prevalence. With the exception of swimming and soccer, the types of sport reported by this schoolchild population do not offer themselves for consideration as tools for LBP prevention. Based on the associations found with indicators of physical inactivity, attempts to motivate the children to increase their general physical activity level should be considered for trial.

Asthma is a major public health problem that affects millions of children worldwide, and exacerbations account for most of its morbidity and costs. Primary-care providers lack efficient tools to identify children at high risk for exacerbations. We aimed to construct a clinical score to help providers to identify such children. Our main outcome was severe asthma exacerbation, which was defined as any hospitalization, urgent visit, or systemic steroid course for asthma in the previous year, in children. A clinical score, consisting of a checklist questionnaire made up of 17 yes-no questions regarding asthma symptoms, use of medications and health-care services, and history, was built and validated in a cross-sectional study of Costa Rican children with asthma. It was then evaluated using data from the Childhood Asthma Management Program (CAMP), a longitudinal trial cohort of North American children. Compared with children at average risk for an exacerbation in the Costa Rican validation set, the odds of an exacerbation among children in the low-risk (OR, 0.2; 95% CI, 0.1-0.4) and high-risk (OR, 5.4; 95% CI, 1.5-19.2) score categories were significantly reduced and increased, respectively. In CAMP, the hazard ratios for an exacerbation after 1-year follow-up in the low-risk and high-risk groups were 0.6 (95% CI, 0.5-0.7) and 1.9 (95% CI, 1.4-2.4), respectively, with similar results at 2 years. The proposed Asthma Exacerbation Clinical Score is simple to use and effective at identifying children at high and low risk for asthma exacerbations. The tool can easily be used in primary-care settings.

Development of an educational cartoon to prevent worm infections in Chinese schoolchildren
2013-01-01
Background With more than two billion people infected worldwide, soil-transmitted helminths (STH) are the most widespread infections. To date, STH control efforts rely predominantly on recurrent mass drug administration (MDA), which does not prevent reinfection. Additional public health measures including novel health educational tools are required for more sustained integrated control of STH. We describe the development of an educational cartoon video (The Magic Glasses) targeting STH infections in Chinese schoolchildren and its pilot testing in China. We applied an extensive community-based mixed methods approach involving input from the target group of 9–10 year old schoolchildren and key informants, such as teachers, doctors and parents, in order to identify potential STH infection risks in the study area and to formulate key messages for the cartoon. The development of the educational cartoon included three major steps: formative research, production, and pilot testing and revision. Results We found that most adults and approximately 50% of the schoolchildren were aware of roundworm (Ascaris) infection, but knowledge of transmission, prevention and treatment of STH was poor. Observations in the study area showed that unhygienic food practices, such as eating raw and unwashed fruit or playing in vegetable gardens previously fertilised with human faeces, posed major STH infection risks. Conclusions It was crucial to assess the intellectual, emotional, social and cultural background of the target population prior to video production in order to integrate the key messages of the cartoon into everyday situations. Overall, our strategy for the development of the cartoon and its incorporation into a health education package proved successful, and we provide a summary of recommendations for the development of future educational videos based on our experiences in China.

BACKGROUND Epidemics of hospitalization for chronic obstructive pulmonary disease (COPD) occur annually during the Christmas holidays, and COPD exacerbations commonly coincide with respiratory viral infections. OBJECTIVE To compare the incidence and determinants of COPD exacerbations occurring between the Christmas holiday period and the remainder of the winter season. METHODS Seventy-one subjects with COPD of mixed severity faxed daily symptom diaries to a computer monitoring system from December 1, 2006, to April 30, 2007. Possible exacerbations prompted a home visit for assessment, spirometry and specimen collection for virological testing. RESULTS Study subjects submitted a total of 95.4% of possible daily symptom diary sheets by fax. Of 114 possible COPD exacerbations detected using the faxed diaries, 110 met the Anthonisen criteria for true exacerbations. A total of 47 exacerbations (mean 6.7/week) occurred during the Christmas holiday period, while 63 exacerbations (mean 4.3/week) occurred during the remainder of winter. Of the Christmas period exacerbations and of those in the balance of winter, 21 (44%) and 20 (32%), respectively, coincided with respiratory viral infections. CONCLUSIONS The incidence of COPD exacerbations during the Christmas period was greater than during the rest of winter in 2006/2007 and peaked immediately before Christmas – in contrast to hospital presentation for COPD, which peaked during the Christmas week. No clear role of respiratory viral infections in the increased rate of exacerbations during the Christmas period was established in the present study. COPD patients were highly compliant with daily symptom reporting using faxed daily diaries, which permitted nearly complete detection of all exacerbations that occurred at incidence. PMID:21165349
Physical self-efficacy is associated to body mass index in schoolchildren.
Carissimi, Alicia; Adan, Ana; Tonetti, Lorenzo; Fabbri, Marco; Hidalgo, Maria Paz; Levandovski, Rosa; Natale, Vincenzo; Martoni, Monica
The present study aimed to investigate the relationship between physical self-efficacy and body mass index in a large sample of schoolchildren. The Perceived Physical Ability Scale for Children was administered to 1560 children (50.4% boys; 8-12 years) from three different countries. Weight and height were also recorded to obtain the body mass index. In agreement with the literature, the boys reported greater perceived physical self-efficacy than girls. Moreover, the number of boys who are obese is double that of girls, while the number of boys who are underweight is half that found in girls. In the linear regression model, the increase in body mass index was negatively related to the physical self-efficacy score, differently for boys and girls. Furthermore, age and nationality also were predictors of low physical self-efficacy only for girls. The results of this study reinforce the importance of psychological aspect of obesity, as the perceived physical self-efficacy and body mass index were negatively associated in a sample of schoolchildren for boys and girls.

Background and objective In resource-poor settings, micronutrient deficiencies such as vitamin A deficiency may co-exist with iron-deficiency. In this study we assessed the iron and vitamin A status of schoolchildren and the association between vitamin A and iron status. Methods A cross-sectional design using the baseline data of a dietary intervention trial conducted among randomly selected 5–12 years old schoolchildren (n = 224) from 2 rural schools in northern Ghana. Hemoglobin (Hb), serum ferritin (SF) and serum transferrin receptor (sTfR) concentrations were used as measures of iron status. Retinol binding protein (RBP) was used as a measure of vitamin A status. Subclinical inflammation (SCI) was measured using C-reactive protein (CRP) and α1-acid glycoprotein (AGP) concentrations. We examined the cross-sectional association between vitamin A and iron status biomarkers with multiple linear regressions. Results The proportions of schoolchildren with anemia (WHO criteria), iron-deficiency (ID, SF <15μg/l and/or sTfR >8.5mg/l) and iron-deficiency anemia (IDA, concurrent anemia and ID) were 63.8%, 68.3% and 46.4% respectively. Low or marginal vitamin A status (0.70 μmol/l ≤ RBP < 1.05μmol/l) was present in 48.2% while 37.5% of the schoolchildren had vitamin A deficiency (VAD, RBP <0.70 μmol/l). The prevalence of SCI as well as concurrent VAD and ID were 48.7% and 25% respectively. RBP was associated with Hb (β = 7.2, P = 0.05) but not SF (β = 20.7, P = 0.33) and sTfR concentration (β = 12.0, P = 0.63). In the presence of SCI, RBP was not associated with hemoglobin status but a significant positive association was observed among children without SCI. Conclusions The study shows that RBP is significantly associated with Hb concentration but not with SF and sTfR. The observed relationship between RBP and Hb is only significant in the absence of SCI. PMID:28152069

To report on the periodontal status of schoolchildren in urban and rural Nepal and to identify possible risk indicators of poor periodontal health. Cross-sectional 'pathfinder' survey using the stratified cluster sampling technique included seven urban and nine rural sites representing the three geographic divisions and five political regions of Nepal. Second stage sampling involved the random selection of 25 schools (18 government and seven private). Final study population consisted of three age groups: 5-6-years (n=1025), 12-13-years (n=1037) and 15-16-years (n=1053). Periodontal data was collected using CPI based on WHO methodology and criteria by trained examiners. A structured questionnaire was administered to collect information on oral health behavior and socio-economic status. A gradual decline in the mean number of healthy sextants was noted with an increase in age among the schoolchildren. Males and females within a specific school and area showed no statistical significant difference when assessed for differences in score 0 (healthy periodontium) among all age groups except for 15-16-year-olds studying in government-urban schools. Multivariate logistic regression analyses showed that children 5 to 6 years of age studying in government urban (Adjusted Odds Ratio = 1.5, 95% Confidence Interval = 1.1-2.1) and government rural schools (Adj OR = 2.8, 95% CI 1.9-4.1) were at higher risk of having periodontal conditions (CPI scores >0) when compared to those in private urban schools. The probability of poorer periodontal status increased for 12 to 13 (Adjusted OR = 1.9, 95% CI 1.3-2.9) and 15 to 16-year-old children (Adjusted OR = 1.7, 95% CI 1.1-2.5) who studied in government rural schools. A steady increase in periodontal conditions was observed with increasing age. The main risk indicator for unhealthy periodontal status at 5-6 years was studying and residing in government rural and urban schools; while the indicator of unhealthy periodontal status for

Practitioners and policy-makers need information about the relative frequency of dental anomalies among children in their region. This study investigated the prevalence of different oral anomalies among schoolchildren in Sana'a city, Yemen. A sample of 1000 private and public schoolchildren aged 4-12 years were examined by the same examiner using disposable tongue blades. The total prevalence of oral anomalies was 15.1%, most commonly in boys (male:female ratio 3.2:1) aged 7-12 years. The most prevalent dental anomaly related to hard tissues was tooth hypoplasia (2.8%), followed by hypocalcification (2.6%), then microdontia (0.5%), macrodontia (0.4%), hypodontia (0.4%), supernumerary teeth (0.3%), tooth transposition (0.3%), dental fusion (0.2%) and gemination (0.2%). The most prevalent soft tissues anomaly was fissured tongue (4.0%), followed by ankyloglossia (1.8%), geographic tongue (0.9%), macroglossia (0.4%) and hairy tongue (0.3%). Appropriate measures need to be taken early to mitigate the negative impact and later costs of treatment of anomalies.

Among the causes of obesity, environmental factors have also been studied, in addition to genetic, social, psychological, and hormonal factors. The distribution of food outlets, facilitating or hindering food acquisition, can promote body weight control by encouraging healthier food habits. The objective of this study was to investigate associations between environmental availability and utilization of food outlets and overweight/obesity in 7 to 14-year-old schoolchildren in Florianópolis, in the South of Brazil. A logistic regression analysis identified a positive association between overweight/obesity in 2195 schoolchildren and the presence of restaurants in the vicinity of their homes (buffer = 400 meters). Being a member of a family that utilizes public markets/greengrocers was also positively associated with overweight/obesity in the sample investigated. Identifying the distribution of these establishments in the vicinity of the homes of schoolchildren in middle-income countries is an important element in understanding the role played by the food environment in weight gain in a variety of different settings.

To assess the association of parents' nutritional status, and dietary and sociodemographic factors with overweight/obesity in schoolchildren in Florianópolis Island, Santa Catarina State, Brazil, this cross-sectional epidemiological study examined 2,826 schoolchildren 7 to 14 years old, classified according to body mass index curves for age and sex recommended by the International Obesity Task Force. Data were analyzed using Poisson regression. The final model showed overweight/obesity in boys associated directly with father's educational level, mother's age, and parents' nutritional status, and inversely with mother's educational level, and number of daily meals. Among girls, it associated directly with parents' nutritional status and the schoolchildren's age, and inversely with consumption of risk foods. The variables that associated with overweight/obesity differed between the sexes, except parents' nutritional status. Boys and girls with both parents overweight or obese were, respectively, 80% and 150% more likely to exhibit the same diagnosis, indicating the need for interventions that include the family environment.

In this study, we investigated the occurrence of viral infections in acute exacerbations of chronic obstructive pulmonary disease (COPD) during four seasons. Viral infections were detected by the use of real-time reverse transcriptase polymerase chain reaction on pharyngeal swabs. During a 12-month period pharyngeal swabs were obtained in 136 exacerbations of 63 patients. In 35 exacerbations (25.7%) a viral infection was detected. Most viral infections occurred in the winter (n = 14, 40.0%), followed by summer (n = 9, 25.7%), autumn (n = 6, 17.1%), and spring (n = 6, 17.1%). Rhinovirus was the most frequently isolated virus (n = 19, 51.4%), followed by respiratory syncytial virus (n = 6, 16.2%), human metapneumovirus (n = 5, 13.5%), influenza A (n = 4, 10.8%), parainfluenza 4 (n = 2, 5.4%), and parainfluenza 3 (n = 1, 2.7%). This study showed that virus-induced COPD exacerbations occur in all four seasons with a peak in the winter months. However, the distribution of rhinovirus infections showed a different pattern, with most infections occurring in July.

To investigate the prevalence of obesity and associated cardiovascular risk factors in schoolchildren in our city, given the influence of these factors on the development of atherosclerosis. We studied a representative sample of second grade students composed of 370 children aged 7.82+/-0.62 years (47.8% girls and 52.2% boys); 52.4% were from public schools and 47.6% were from private schools. Surveys were performed and anthropometric measurements, blood pressure (BP) values and glucose and lipid profiles in capillary blood were determined. A total of 9.7% (36 schoolchildren) were obese and 13.8% were overweight. There were no differences according to sex or school system. Abdominal obesity was observed in 69.4% (p<0.0001), normal-high BP (90-97th percentile) in 27.8% (p<0.0001), dyslipidemia in 66.7% (p<0.05) and metabolic syndrome in 38.9% (p<0.0001) of the obese children compared with 1.3%, 5.1%, 48.9% and 0.4% of the children with normal weight, respectively. No association was found between fasting hyperglycemia and obesity. There were no cases of hypertension or diabetes mellitus. The risk (odds ratio) for normal-high BP, dyslipidemia, abdominal obesity and metabolic syndrome was 6.3, 2.2, 60.9, and 70.2 times higher in obese children than in non-obese children, respectively. A positive and significant correlation was found between waist circumference and body mass index with BP and the atherogenic indexes triglycerides/high-density lipoprotein cholesterol (HDL-C), total cholesterol/HDL-C and low-density lipoprotein cholesterol/HDL-C (p=0.0001). Compared with cities in other countries, the city of Mérida, Venezuela, has an intermediate prevalence of overweight and obesity in schoolchildren. The high frequency of cardiovascular risk factors in the obese and its positive correlation with adiposity highlights the need to implement population-based strategies for its prevention in childhood.

Asthma is a common chronic condition that places substantial burden on patients and healthcare services. Despite the standards of asthma control that international guidelines recommend should be achieved, many patients continue to suffer sub-optimal control of symptoms and experience exacerbations (acute asthma attacks). In addition to being associated with reduced quality of life, asthma exacerbations are a key cost driver in asthma management. Routine clinical practice for the management of asthma exacerbations varies in different healthcare systems, so healthcare providers require local costs to be able to assess the value of therapies that reduce the frequency and severity of exacerbations. This prospective study, conducted in a total of 15 countries, assessed the local cost of asthma exacerbations managed in either primary or secondary care. Healthcare resources used were costed using actual values appropriate to each country in local currency and in Euros. Results are presented for exacerbations managed in primary care in Brazil, Bulgaria, Croatia, Czech Republic, Hungary, Poland, Russia, Slovakia, Slovenia, Spain and Ukraine, and in secondary care in Croatia, Denmark, Ireland, Latvia, Norway, Poland, Russia, Slovakia, Slovenia and Spain. Multiple regression analysis of the 2052 exacerbations included in the economic analysis showed that the cost of exacerbations was significantly affected by country (P<0.0001). Mean costs were significantly higher in secondary care (euro 1349) than primary care (euro 445, P=0.0003). Age was a significant variable (P=0.0002), though the effect showed an interaction with care type (P<0.0001). As severity of exacerbation increased, so did secondary care costs, though primary care costs remained essentially constant. In conclusion, the study showed that asthma exacerbations are costly to manage, suggesting that therapies able to increase asthma control and reduce the frequency or severity of exacerbations may bring economic

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are critical events associated with accelerated loss of lung function, increased morbidity, and excess mortality. AECOPD are heterogeneous in nature and this may directly impact clinical decision making, specifically in patients with frequent exacerbations. A “frequent exacerbator” is a sub-phenotype of COPD that is defined as an individual who experiences ≥2 moderate to severe exacerbations per year. This distinct subgroup has higher mortality and account for more than half of COPD-related hospitalizations annually. Thus, it is imperative to identify individuals at risk for frequent exacerbations and choose optimal strategies to minimize risk for these events. New paradigms for utilizing combination inhalers and the introduction of novel oral compounds provide expanded treatment options to reduce the risk and frequency of exacerbations. The goals of managing frequent exacerbators or patients at risk for AECOPD are: 1) maximizing bronchodilation, 2) reducing inflammation, and 3) targeting specific molecular pathways implicated in COPD and AECOPD pathogenesis. Novel inhaler therapies include combination long acting muscarinic agents (LAMA) plus long acting beta agonists (LABA) show promising results compared to monotherapy or LABA inhaled corticosteroid (ICS) combination in reducing exacerbation risk among individuals at risk for exacerbations and among frequent exacerbators. Likewise, oral medications including macrolides and phosphodiesterase (PDE4) inhibitors reduce the risk for AECOPD in select groups of individuals at high risk for exacerbation. Future direction in COPD management is based on identification of various subtypes or “endotypes” and targeting therapies based on their pathophysiology. This review aims to describe the impact of AECOPD, challenges posed by frequent exacerbators, and explores the rationale for different pharmacologic approaches to preventing AECOPD in these

Background: Little is known about folate and atopy or severe asthma exacerbations. We examined whether folate deficiency is associated with number of positive skin tests to allergens or severe asthma exacerbations in a high-risk population and further assessed whether such association is explained or modified by vitamin D status. Methods: Cross-sectional study of 582 children aged 6 to 14 years with (n = 304) and without (n = 278) asthma in San Juan, Puerto Rico. Folate deficiency was defined as plasma folate less than or equal to 20 ng/ml. Our outcomes were the number of positive skin tests to allergens (range, 0–15) in all children and (in children with asthma) one or more severe exacerbations in the previous year. Logistic and negative binomial regression models were used for the multivariate analysis. All multivariate models were adjusted for age, sex, household income, residential proximity to a major road, and (for atopy) case/control status; those for severe exacerbations were also adjusted for use of inhaled corticosteroids and vitamin D insufficiency (a plasma 25[OH]D < 30 ng/ml). Measurements and Main Results: In a multivariate analysis, folate deficiency was significantly associated with an increased degree of atopy and 2.2 times increased odds of at least one severe asthma exacerbation (95% confidence interval for odds ratio, 1.1–4.6). Compared with children who had normal levels of both folate and vitamin D, those with both folate deficiency and vitamin D insufficiency had nearly eightfold increased odds of one or more severe asthma exacerbation (95% confidence interval for adjusted odds ratio, 2.7–21.6). Conclusions: Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations. PMID:26561879

Background: Asthma is a major public health problem that affects millions of children worldwide, and exacerbations account for most of its morbidity and costs. Primary-care providers lack efficient tools to identify children at high risk for exacerbations. We aimed to construct a clinical score to help providers to identify such children. Methods: Our main outcome was severe asthma exacerbation, which was defined as any hospitalization, urgent visit, or systemic steroid course for asthma in the previous year, in children. A clinical score, consisting of a checklist questionnaire made up of 17 yes-no questions regarding asthma symptoms, use of medications and health-care services, and history, was built and validated in a cross-sectional study of Costa Rican children with asthma. It was then evaluated using data from the Childhood Asthma Management Program (CAMP), a longitudinal trial cohort of North American children. Results: Compared with children at average risk for an exacerbation in the Costa Rican validation set, the odds of an exacerbation among children in the low-risk (OR, 0.2; 95% CI, 0.1-0.4) and high-risk (OR, 5.4; 95% CI, 1.5-19.2) score categories were significantly reduced and increased, respectively. In CAMP, the hazard ratios for an exacerbation after 1-year follow-up in the low-risk and high-risk groups were 0.6 (95% CI, 0.5-0.7) and 1.9 (95% CI, 1.4-2.4), respectively, with similar results at 2 years. Conclusions: The proposed Asthma Exacerbation Clinical Score is simple to use and effective at identifying children at high and low risk for asthma exacerbations. The tool can easily be used in primary-care settings. PMID:20472862

Adults who smoke increase their likelihood of death from smoking-exacerbated illnesses. The presence of illnesses exacerbated by smoking can be a powerful incentive to quit smoking. However, having a smoking-exacerbated illness does not stop all patients from smoking. Understanding that smoking may be a coping mechanism for stress, this study examined the association between the experiences of adverse events in childhood with continued smoking in adulthood among individuals and a smoking-exacerbated illness. This retrospective observational study used 2014-2015 data from the South Carolina Behavioral Risk Factor Surveillance System survey. We used multivariable logistic regression to examine the impact of adverse childhood experience (ACE) exposure on current smoking status. A total of 6321 respondents reported having a smoking-exacerbated illness. The most frequently reported categories of smoking-exacerbated illnesses were current asthma (63.9%), previous asthma (13.0%), and diabetes (12.3%). Overall, 62.4% of respondents had at least one ACE, with 20.3% of respondents having four or more ACEs. Respondents with one to three ACEs (adjusted odds ratio [aOR] 1.38; 95% confidence interval [CI] 1.37-1.40) and four or more ACEs (aOR 2.89; CI 2.86-2.92) were both significantly more likely to smoke than respondents with no ACEs, even in the presence of illnesses exacerbated by smoking. Results suggest that ACE exposure may influence risky health behaviors in adulthood, such as continued smoking even in the presence of illnesses that are exacerbated by smoking. Given that smoking has been found to be a coping mechanism for adversity, anti-smoking efforts might benefit from designing interventions and treatment plans that address ACE exposure.

Depressive symptoms in the young constitute a public health issue. The current study aims to estimate: (a) the frequency of depressive symptoms in a sample of final grade elementary-school children in Cyprus, (b) the association among frequency of depressive symptoms, gender and nationality and, (c) the metric properties of the Greek-Cypriot version of the children's depression inventory (CDI). A descriptive cross-sectional study with internal comparison was performed. The occurrence of depressive symptoms was assessed with the CDI, which includes 5 subscales: depressive mood, interpersonal difficulties, ineffectiveness, anhedonia and negative self-esteem. Clinical depressive symptoms were reported as CDI score ≥19. CDI was anonymously and voluntarily completed by 439 schoolchildren [mean age 12.3 (±0.51) years old] from fifteen public elementary schools (217 boys and 222 girls), yielding a response rate of 58.2%. The metric properties of the CDI were assessed in terms of internal consistency reliability and construct validity via exploratory factor analysis (rotated and unrotated principal component analysis). Descriptive and inferential statistics were explored. 10.25% of Cypriot schoolchildren reported clinical depressive symptoms (CDI score ≥19). Statistically significant differences were reported between boys and girls in all five subscales of the CDI. Girls reported higher scores in "Depressive mood", "Negative self-esteem" and "Anhedonia" subscales, while boys scored higher in "Interpersonal difficulties" and "Ineffectiveness" subscales. There were no statistically significant differences among ethnicity groups regarding the entire CDI or the subscales of it. Concerning the metric properties of the Greek-Cypriot version of the CDI, internal consistency reliability was adequate (Cronbach's alpha = 0.84). Factor analysis with varimax rotation resulted in five factors explaining 42% of the variance. The Greek-Cypriot version of the CDI is a reliable

Studies indicate that asymptomatic infections do indeed occur frequently for both seasonal and pandemic influenza, accounting for about one-third of influenza infections. Studies carried out during the 2009 pH1N1 pandemic have found significant antibody response against seasonal H1N1 and H3N2 vaccine strains in schoolchildren receiving only pandemic H1N1 monovalent vaccine, yet reported either no symptoms or only mild symptoms. Serum samples of 255 schoolchildren, who had not received vaccination and had pre-season HI Ab serotiters <40, were collected from urban, rural areas and an isolated island in Taiwan during the 2005-2006 influenza season. Their hemagglutination inhibition antibody (HI Ab) serotiters against the 2005 A/New Caledonia/20/99 (H1N1) vaccine strain at pre-season and post-season were measured to determine the symptoms with the highest correlation with infection, as defined by 4-fold rise in HI titer. We estimate the asymptomatic ratio, or the proportion of asymptomatic infections, for schoolchildren during the 2005-6 influenza season when this vaccine strain was found to be antigenically related to the circulating H1N1 strain. Fever has the highest correlation with the 2005-06 seasonal influenza A(H1N1) infection, followed by headache, cough, vomiting, and sore throat. Asymptomatic ratio for the schoolchildren is found to range between 55.6% (95% CI: 44.7-66.4)-77.9% (68.8-87.0) using different sets of predictive symptoms. Moreover, the asymptomatic ratio was 66.9% (56.6-77.2) when using US-CDC criterion of fever + (cough/sore throat), and 73.0 (63.3-82.8) when under Taiwan CDC definition of Fever + (cough or sore throat or nose) + ( headache or pain or fatigue). Asymptomatic ratio for children is found to be substantially higher than that of the general population in literature. In providing reasonable quantification of the asymptomatic infected children spreading pathogens to others in a seasonal epidemic or a pandemic, our estimates

Background: The aim of the present study is to assess the elementary schoolchildren's nutritional status based on anthropometric indices due to the sudden spread of obesity in children and adolescents in both developed and developing countries. Methods: This cross-sectional study was conducted on 3647 children with an age range of 7–11 years of primary schools in Babol using cluster random sampling method in 2012. Children younger than 7 years or older than 11 years, children with chronic diseases, pupils treated with corticosteroids or growth hormone replacement therapy and children with chromosomal abnormalities were excluded from the study. Anthropometric indices were measured by medical students and evaluated according to the Centers for Disease Control and Prevention standard percentiles. Data were analyzed using statistical software SPSS version 18 with Chi-square and independent samples t-test. Results: The body mass index of 26.1% of children was greater than the 85th percentile, and 4.7% was less than the 5th percentile. The prevalence of obesity among boys was significantly higher than girls (P = 0.007). Moreover, urban children (P = 0.0001) and children who studied in private schools (P = 0.0001) had a significantly higher proportion of obesity and overweight than the urban and private schoolstudents. The highest prevalence of obesity and overweight belonged to 18.0% of the students among fifth graders and 15.3% of schoolchildren among third graders, respectively (P < 0.001). Conclusions: The results showed that the prevalence of overweight and obesity in the study was higher. It seems it is necessary to implement the intervention programs to prevent overweight and obesity among schoolchildren. PMID:26605020

Myopia is a complex condition leading to visual impairment and blindness. This study assessed the prevalence of and risk factors for myopia among schoolchildren in urban and rural areas of Armenia. A cross-sectional interviewer-administered survey together with eye screenings was conducted among schoolchildren in the capital Yerevan and in Gegharkunik Province. The study used multi-stage random sampling to obtain the sample of 1260 schoolchildren. Study questionnaires were developed based on the Sydney Myopia Study questionnaire. Continuous reading was defined as the average number of hours spent reading or on near work without a break. Children underwent measurements of visual acuity using a Golovin-Sivtsev eye chart, cycloplegic retinoscopy, and dilated fundus examination. The mean age of the children was 13 years, and myopia was present in 18.1%. The prevalence of myopia was higher among Yerevan children (23.3%) than those living in Gegharkunik Province (12.5%). In the adjusted model, myopia was significantly associated with age (odds ratio, OR, 1.11, 95% confidence interval, CI, 1.04-1.18), region (OR 2.40, 95% CI 1.62-3.57), school achievement (OR 1.62, 95% CI 1.05-2.51), parental myopia (OR 2.89, 95% CI 1.79-4.69), and continuous reading (OR 1.99, 95% CI 1.31-3.02), but not near work (OR 0.97, 95% CI 0.89-1.05). The study found that a positive family history of myopia and environmental factors had independent associations with myopia. The number of near work hours did not play a major role in the development of myopia, but length of time of focused continuous reading did.

The aim of the present study was to assess the prevalence of refractive errors and visual impairment among schoolchildren in rural central Ethiopia. A cross-sectional study was conducted from November 2010 to January 2011 among 5,470 schoolchildren from 14 schools, of whom 4,238 (aged 7-18 years) were screened for refractive errors. In all participants, uncorrected vision and best corrected visual acuity were determined and those with a visual acuity of 6/12 or worse, underwent a complete ophthalmic examination to determine the cause of visual impairment. Myopia was defined as a spherical equivalent of -0.50 dioptre (D) or greater in one or both eyes and hyperopia as a spherical equivalent of +2.00 D or greater. A cylindrical power of -0.50 DC (D cylinder) or greater was considered as astigmatism. Chi-square was used to test differences in proportions. Differences were considered to be statistically significant at the five per cent level. Of the 4,238 children, 405 (9.5 per cent) were visually impaired and of these 267 children were diagnosed as having refractive errors, with an overall prevalence of 6.3 per cent, comprised of 6.1 per cent in boys and 6.6 per cent in girls. Myopia is the most prevalent refractive error; accounting for 6.0 per cent, followed by compound myopic astigmatism 1.2 per cent, then simple myopic astigmatism 0.5 per cent, mixed astigmatism 0.26 per cent and finally hyperopia 0.33 per cent. Reasons for visual acuity of 6/12 or worse in the better eye were found to be refractive error (65.9 per cent), corneal problems (12.8 per cent) and amblyopia (9.6 per cent). The prevalence of manifest strabismus in the study group was 1.1 per cent (n = 45). The study concluded that uncorrected refractive error is a common cause of visual impairment among schoolchildren in rural central Ethiopia. This indicates the need for regular school-screening programs that provide glasses at low cost or free of charge for those who have refractive errors. © 2012 The

to identify the association between the percentage of adequacy of energy and protein and the distribution of macronutrients and sugar in the diets of mothers and schoolchildren with their respective BMI. in a cross-sectional study, 174 5-12-year-old schoolchildren and their mothers were randomly selected. BMI was measured, and 24-hour dietary surveys were administered on weekdays and weekends. The associations between the dietetic indicators in the mothers and their children and the BMI of the mothers and their children were assessed. The chi-square test, linear regression and odds ratio were used for analysis. excessive energy consumption in the mothers increased the risk of excessive energy consumption in their daughters by 11-fold (p=0.04). Maternal lipid intake was associated with the consumption of lipids in their sons and daughters (p. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

To identify the social and environmental determinants most strongly associated with overweight and obesity in Brazilian schoolchildren from a developing region. Data were collected from a community-based survey of schoolchildren from the Valley of Jequitinhonha, Minas Gerais, Brazil. The sample was composed of 5 100 school children aged 6-18 years. Overweight and obesity were defined by body mass index based on the current method recommended by the World Health Organization in 2007. Social and environmental determinants were collected by using a structured questionnaire. The prevalence of overweight and obesity was 11.1% and 2.7% in girls and 8.2% and 1.5% in boys, respectively. The chance of overweight was higher in schoolchildren who engaged in remunerated work (odds ratio [OR] = 2.19, 95% confidence interval [CI] 1.30- 3.26), whose parents had higher education levels (OR = 1.52, 95% CI 1.12-2.07), who had two or fewer siblings (OR = 1.74, 95% CI 1.21-2.49), and who were in a high economic class (OR = 1.93, 95% CI 1.32-2.85). Schoolchildren who traveled by car to school (OR = 1.50, 95% CI 1.14-1.91), lived < 5 km from school (OR = 1.64, 95% CI 1.06-2.39), and consumed foods sold in the school cafeteria (OR = 1.56, 95% CI 1.19-2.16) presented high odds of being overweight. The background from a particular region of a country should be considered when implementing preventive measures regarding overweight and obesity, especially for very poor, developing regions like the Valley of Jequitinhonha. Measures taken should consider a multilevel intervention that includes the family, school, and physical environment.
Hydrogen breath test in schoolchildren.

The frequency of negative hydrogen breath tests due to colonic bacterial flora which are unable to produce hydrogen was determined after oral lactulose challenge in 98 healthy Dutch schoolchildren. There was a negative result in 9.2%. The probability of a false normal lactose breath test (1:77) was calculated from these results together with those from a separate group of children with lactose malabsorption (also determined by hydrogen breath test). A study of siblings and mothers of subjects with a negative breath test did not show familial clustering of this condition. Faecal incubation tests with various sugars showed an increase in breath hydrogen greater than 100 parts per million in those with a positive breath test while subjects with a negative breath test also had a negative faecal incubation test. The frequency of a false negative hydrogen breath test was higher than previously reported, but this does not affect the superiority of this method of testing over the conventional blood glucose determination.

Importance Asthma is common and can be exacerbated by air pollution and stress. Unconventional natural gas development (UNGD) has community and environmental impacts. In Pennsylvania, development began in 2005 and by 2012, 6,253 wells were drilled. There are no prior studies of UNGD and objective respiratory outcomes. Objective To evaluate associations between UNGD and asthma exacerbations. Design A nested case-control study comparing asthma patients with exacerbations to asthma patients without exacerbations from 2005–12. Setting The Geisinger Clinic, which provides primary care services to over 400,000 patients in Pennsylvania. Participants Asthma patients aged 5–90 years (n = 35,508) were identified in electronic health records; those with exacerbations were frequency-matched on age, sex, and year of event to those without. Exposure(s) On the day before each patient’s index date (cases: date of event or medication order; controls: contact date), we estimated UNGD activity metrics for four phases (pad preparation, drilling, stimulation [“fracking”], and production) using distance from the patient’s home to the well, well characteristics, and the dates and durations of phases. Main Outcome(s) and Measure(s) We identified mild, moderate, and severe asthma exacerbations (new oral corticosteroid medication order, emergency department encounter, and hospitalization, respectively). Results We identified 20,749 mild, 1,870 moderate, and 4,782 severe asthma exacerbations, and frequency-matched these to 18,693, 9,350, and 14,104 control index dates, respectively. In three-level adjusted models, there was an association between the highest group of the activity metric for each UNGD phase compared to the lowest group for 11 out of 12 UNGD-outcome pairs (odds ratios [95% CI] ranged from 1.5 [1.2–1.7] for the association of the pad metric with severe exacerbations to 4.4 [3.8–5.2] for the association of the production metric with mild exacerbations).

Methamphetamine use can produce symptoms almost indistinguishable from schizophrenia. Distinguishing between the two conditions has been hampered by the lack of a validated symptom profile for methamphetamine-induced psychiatric symptoms. We use data from a longitudinal cohort study to examine the profile of psychiatric symptoms that are acutely exacerbated by methamphetamine use. 164 methamphetamine users, who did not meet DSM-IV criteria for a lifetime primary psychotic disorder, were followed monthly for one year to assess the relationship between days of methamphetamine use and symptom severity on the 24-item Brief Psychiatric Rating Scale. Exacerbation of psychiatric symptoms with methamphetamine use was quantified using random coefficient models. The dimensions of symptom exacerbation were examined using principal axis factoring and a latent profile analysis. Symptoms exacerbated by methamphetamine loaded on three factors: positive psychotic symptoms (suspiciousness, unusual thought content, hallucinations, bizarre behavior); affective symptoms (depression, suicidality, guilt, hostility, somatic concern, self-neglect); and psychomotor symptoms (tension, excitement, distractibility, motor hyperactivity). Methamphetamine use did not significantly increase negative symptoms. Vulnerability to positive psychotic and affective symptom exacerbation was shared by 28% of participants, and this vulnerability aligned with a past year DSM-IV diagnosis of substance-induced psychosis (38% vs. 22%, χ(2)(df1)=3.66, p=0.056). Methamphetamine use produced a symptom profile comprised of positive psychotic and affective symptoms, which aligned with a diagnosis of substance-induced psychosis, with no evidence of a negative syndrome.

Chemotherapy with praziquantel (PZQ) is the mainstay of schistosomiasis control. However, there are recent concerns about tolerance or resistance to PZQ, so that monitoring its efficacy in different settings is required. A longitudinal study was conducted to evaluate the impact of PZQ for the treatment of Schistosoma haematobium infection among schoolchildren at Al Salamania, Central Sudan. Parasitological examinations for S. haematobium were performed in a cohort of schoolchildren (6-15 years of age) before and 1 year after treatment with a single dose of PZQ 40 mg/kg. Out of 562 (309 boys and 253 girls) schoolchildren recruited from three elementary schools, 420 completed one longitudinal dataset that comprised of data from two time points; baseline, and follow-up 1 year after treatment with a single dose of PZQ 40 mg/kg for S. haematobium infection. A single dose of PZQ significantly reduced the prevalence of S. haematobium infection by 83.3% (from 51.4% to 8.6%) and the geometric mean intensity of infection of positive individuals by 17.0% (from 87.7 to 72.8 eggs/10 ml of urine) 1 year after treatment. While there was no significant difference in the reduction of the prevalence of S. haematobium infection between the gender or age groups, there was a significantly higher reduction of intensity of S. haematobium infection among girls in comparison with boys. There was a significant reduction of S. haematobium infection 1 year after PZQ treatment in this setting.

Asthma is a heterogeneous disease characterized by various types of airway inflammation and obstruction. Therefore, it is classified into several subphenotypes, such as early-onset atopic, obese non-eosinophilic, benign, and eosinophilic asthma, using cluster analysis. A number of asthmatics frequently experience exacerbation over a long-term follow-up period, but the exacerbation-prone subphenotype has rarely been evaluated by cluster analysis. This prompted us to identify clusters reflecting asthma exacerbation. A uniform cluster analysis method was applied to 259 adult asthmatics who were regularly followed-up for over 1 year using 12 variables, selected on the basis of their contribution to asthma phenotypes. After clustering, clinical profiles and exacerbation rates during follow-up were compared among the clusters. Four subphenotypes were identified: cluster 1 was comprised of patients with early-onset atopic asthma with preserved lung function, cluster 2 late-onset non-atopic asthma with impaired lung function, cluster 3 early-onset atopic asthma with severely impaired lung function, and cluster 4 late-onset non-atopic asthma with well-preserved lung function. The patients in clusters 2 and 3 were identified as exacerbation-prone asthmatics, showing a higher risk of asthma exacerbation. Two different phenotypes of exacerbation-prone asthma were identified among Korean asthmatics using cluster analysis; both were characterized by impaired lung function, but the age at asthma onset and atopic status were different between the two.

The main purpose of the present study was to examine the effects of a physical education-based stretching development and maintenance program on hamstring extensibility in schoolchildren. A sample of 150 schoolchildren aged 7-10 years old from a primary school participated in the present study (140 participants were finally included). The six classes balanced by grade were cluster randomly assigned to the experimental group 1 (n = 51), experimental group 2 (n = 51) or control group (n = 49) (i.e., a cluster randomized controlled trial design was used). During the physical education classes, the students from the experimental groups 1 and 2 performed a four-minute stretching program twice a week for nine weeks (first semester). Then, after a five-week period of detraining coinciding with the Christmas holidays, the students from the experimental groups 1 and 2 completed another stretching program twice a week for eleven weeks (second semester). The students from the experimental group 1 continued performing the stretching program for four minutes while those from the experimental group 2 completed a flexibility maintenance program for only one minute. The results of the two-way analysis of variance showed that the physical education-based stretching development program significantly improved the students’ hamstring extensibility (p < 0.001), as well as that these gains obtained remained after the stretching maintenance program (p < 0.001). Additionally, statistically significant differences between the two experimental groups were not found (p > 0.05). After a short-term stretching development program, a physical education-based stretching maintenance program of only one-minute sessions twice a week is effective in maintaining hamstring extensibility among schoolchildren. This knowledge could help and guide teachers to design programs that allow a feasible and effective development and maintenance of students’ flexibility in the physical education setting. Key
[The Chinese experts' consensus on the evaluation and management of asthma exacerbation].
2018-01-01
Asthma exacerbations can do a lot of harm to the patients and consume large amounts of medical resources. This consensus is based on the domestic and foreign guidelines and literatures to standardize the evaluation and management of asthma exacerbations in China. Asthma exacerbations are characterized by a progressive increase in symptoms of shortness of breath, cough, wheezing or chest tightness and progressive decrease in lung function, and usually require modification of treatment. Recognizing risk factors and triggering factors of asthma exacerbations is helpful for the prevention and long-term management. Evaluation of asthma exacerbations is based on symptoms, lung function, and arterial blood gas. Management is stratified according to the severity of disease. Different regimens to treat asthma exacerbations are discussed in this consensus. Glucocorticoids should be used properly. Overuse of antibiotics should be avoided. Management of life-threatening asthma is discussed separately. Special attention should be paid in some special respects, such as asthma during peri-operation period, gestation period, and childhood. Diagnosis and management of complications are also of great significance and are discussed in details.
Bicycle ownership, use, and injury patterns among elementary schoolchildren
Waller, Julian A
1995-01-01
Patterns of bicycle ownership and injury were studied over a four month period among over 6000 schoolchildren. Two thirds of the bikes owned were standard style and one third high rise. Boys more often had high rise bikes. Slightly over 2% of bike owners are injured annually, but no differences were found according to bike style either in injury rate or severity. Bike borrowing and riding double were common factors in the injury events. Injury from spokes and loss of control because of loose handlebars were identified as problems resulting from product design. PMID:9346042

Background Progress toward reducing the malaria burden in Africa has been measured, or modeled, using datasets with relatively short time-windows. These restricted temporal analyses may miss the wider context of longer-term cycles of malaria risk and hence may lead to incorrect inferences regarding the impact of intervention. Methods 1147 age-corrected Plasmodium falciparum parasite prevalence (PfPR2-10) surveys among rural communities along the Kenyan coast were assembled from 1974 to 2014. A Bayesian conditional autoregressive generalized linear mixed model was used to interpolate to 279 small areas for each of the 41 years since 1974. Best-fit polynomial splined curves of changing PfPR2-10 were compared to a sequence of plausible explanatory variables related to rainfall, drug resistance and insecticide-treated bed net (ITN) use. Results P. falciparum parasite prevalence initially rose from 1974 to 1987, dipped in 1991–92 but remained high until 1998. From 1998 onwards prevalence began to decline until 2011, then began to rise through to 2014. This major decline occurred before ITNs were widely distributed and variation in rainfall coincided with some, but not all, short-term transmission cycles. Emerging resistance to chloroquine and introduction of sulfadoxine/pyrimethamine provided plausible explanations for the rise and fall of malaria transmission along the Kenyan coast. Conclusions Progress towards elimination might not be as predictable as we would like, where natural and extrinsic cycles of transmission confound evaluations of the effect of interventions. Deciding where a country lies on an elimination pathway requires careful empiric observation of the long-term epidemiology of malaria transmission. PMID:26107772

Objectives We undertook this study in Kenya to understand the community's emergency care needs and barriers they face when trying to access care, and to seek community members’ thoughts regarding high impact solutions to expand access to essential emergency services. Design We used a qualitative research methodology to conduct 59 focus groups with 528 total Kenyan community member participants. Data were coded, aggregated and analysed using the content analysis approach. Setting Participants were uniformly selected from all eight of the historical Kenyan provinces (Central, Coast, Eastern, Nairobi, North Eastern, Nyanza, Rift Valley and Western), with equal rural and urban community representation. Results Socioeconomic and cultural factors play a major role both in seeking and reaching emergency care. Community members in Kenya experience a wide range of medical emergencies, and seem to understand their time-critical nature. They rely on one another for assistance in the face of substantial barriers to care—a lack of: system structure, resources, transportation, trained healthcare providers and initial care at the scene. Conclusions Access to emergency care in Kenya can be improved by encouraging recognition and initial treatment of emergent illness in the community, strengthening the pre-hospital care system, improving emergency care delivery at health facilities and creating new policies at a national level. These community-generated solutions likely have a wider applicability in the region. PMID:26586324

Background: The incidence of obesity in children is increasing worldwide, primarily in urbanized, high-income countries, and hypertension development is a detrimental effect of this phenomenon. Objective: In this cross-sectional study, we evaluated the prevalence of excess weight and its association with high blood pressure (BP) in schoolchildren. Methods: Here 4,609 male and female children, aged 6 to 11 years, from 24 public and private schools in Maringa, Brazil, were evaluated. Nutritional status was assessed by body mass index (BMI) according to cutoff points adjusted for sex and age. Blood pressure (BP) levels above 90th percentile for gender, age and height percentile were considered elevated. Results: The prevalence of excess weight among the schoolchildren was 24.5%; 16.9% were overweight, and 7.6% were obese. Sex and socioeconomic characteristics were not associated with elevated BP. In all age groups, systolic and diastolic BP correlated with BMI and waist and hip measurements, but not with waist-hip ratio. The prevalence of elevated BP was 11.2% in eutrophic children, 20.6% in overweight children [odds ratio (OR), 1.99; 95% confidence interval (CI), 1.61-2.45], and 39.7% in obese children (OR, 5.4; 95% CI, 4.23-6.89). Conclusion: Obese and overweight children had a higher prevalence of elevated BP than normal-weight children. Our data confirm that the growing worldwide epidemic of excess weight and elevated BP in schoolchildren may also be ongoing in Brazil. PMID:25076178

The aim of the present study was to estimate the associations between the prevalence of asthma symptoms in schoolchildren and meteorological variables in west European countries that participated in the International Study of Asthma and Allergies in Children (ISAAC), Phase III 1997-2003. An ecologic study was carried out. The prevalence of asthma was obtained from this study from 48 centers in 14 countries, and meteorological variables from those stations closest to ISAAC centers, together with other socioeconomic and health care variables. Multilevel mixed-effects linear regression models were used. For schoolchildren aged 6-7 years, the prevalence rate of asthma decreased with an increase in mean annual sunshine hours, showed a positive association with rainy weather, and warm temperature, and a negative one with relative humidity and physician density (PD). Current wheeze prevalence was stronger in autumn/winter seasons and decreased with increasing PD. Severe current wheeze decreased with PD. For schoolchildren aged 13-14 years, the prevalence rates of asthma and current wheeze increased with rainy weather, and these rates decreased with increased PD. Current wheeze, as measured by a video questionnaire, was inversely associated with sunny weather, and nurse density. Severe current wheeze prevalence was stronger during autumn/winter seasons, decreased with PD, and indoor chlorinated public swimming pool density, and increased with rainy weather. Meteorological factors, including sunny and rainy weather, and PD may have some effect on the prevalence rates of asthma symptoms in children from west European countries.

This study examined the effectiveness of Chinese martial arts in reducing reactive and proactive aggressive behavior among schoolchildren with a cluster-randomized trial. A screening questionnaire was completed by 3511 schoolchildren of Grades 2 to 5 from 13 sites in Hong Kong. We shortlisted 298 children who scored z ≥ 1 on the total score of the Reactive-Proactive Aggression Questionnaire in their respective sites to participate in the experiment. They were divided into 31 clusters that were blinded and randomly assigned to one of the 4 conditions: skills only, philosophy only, skills and philosophy, and physical fitness (placebo). Subjects were assessed at baseline, posttraining, and 6 months after training using aggression scales. Results from the linear mixed model indicated that the time × training interaction effects were significant for aggressive behavior (reactive and proactive), delinquent behavior, anxiety/depression, and attention problems. Although all measures declined in all conditions over time, only the skills-and-philosophy condition showed a significant reduction at posttraining and/or 6-month follow-up compared with the placebo. The results provided a theoretical proof for the relationship between aggression and sport involvement combined with children's moral reasoning. This study gives practical implications to intervention that solely playing sports or teaching moral lessons is not effective enough for high-risk schoolchildren with aggressive behavior. However, combined traditional Chinese martial arts skills and moral philosophy training could be considered in the school curriculum to reduce school violence and facilitate creation of harmonious schools.
Social scripts and stark realities: Kenyan adolescents' abortion discourse.

2006-01-01
This study explores students' narratives and discourses about adolescent pregnancy and abortion elicited via internet-based open-ended questions posed in response to a cartoon vignette. We report on content analysis of recommendations and strategies for how to manage the unplanned pregnancy of a fictional young couple and in their own personal lives. The responses of 614 young people were analysed. Strategies vary widely. They include giving birth, adoption, running away, abortion, denial, and postponement until discovery. Young people were also queried about unplanned pregnancy resolution among their peers. Discourse analysis reveals competing social scripts on abortion. Florid condemnation of abortion acts in the hypothetical cases contrasts with more frank and sober description of peers' real life abortion behaviour. Students' language is compared with that found in official curricula. The rhetorical devices, moralizing social scripts and dubious health claims about abortion in students' online narratives mirror the tenor and content of their academic curricula as well as Kenyan media presentation of the issue. The need for factual information, dispassionate dialogue and improved contraceptive access is considerable.
Gender scripts and unwanted pregnancy among urban Kenyan women.

2011-10-01
Women's lived experiences and lay accounts of unwanted pregnancy remain poorly interrogated. We investigated portrayals of unwanted pregnancy using narrative data gathered from 80 women in Nairobi, Kenya. Unwanted pregnancy had a diversity of significance for the women. Pregnancies were not simply unwanted because they occurred when women became pregnant without wanting to. Rather, pregnancies were considered unwanted largely because they had occurred in contexts that did not reinforce socially-sanctioned notions of motherhood and 'proper' procreation and/or revealed women's use of their sexuality in ways deemed culturally-inappropriate. Kenyan women's invocation of femininity scripts to explain unwanted pregnancy; the centrality of gender in everyday life in contemporary Kenya; women's and girls' poor access to effective family planning services; growing female poverty; and Kenya's restrictive abortion policy imply that unwanted pregnancy and its consequences will persist in the country. Addressing unwanted pregnancy and its consequences requires making accessible quality contraceptive and abortion services as well as sexuality information. It also calls for providers who understand the socio-cultural norms that circumscribe fertility and reproductive behaviours.
Chronic obstructive pulmonary disease exacerbations: latest evidence and clinical implications
Qureshi, Hammad; Sharafkhaneh, Amir
2014-01-01
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing. The natural history of COPD is punctuated by exacerbations which have major short- and long-term implications on the patient and healthcare system. Evidence-based guidelines stipulate that early detection and prompt treatment of exacerbations are essential to ensure optimal outcomes and to reduce the burden of COPD. Several factors can identify populations at risk of exacerbations. Implementing prevention measures in patients at risk is a major goal in the management of COPD. PMID:25177479

The prevalence of high blood pressure in children is increasing worldwide, largely, but not entirely, driven by the concurrent childhood obesity epidemic. The aims of this study were to examine the prevalence of prehypertension and hypertension in 4-to-6-year-old Spanish schoolchildren, and to evaluate the association between different blood pressure (BP) components with different adiposity indicators. Cross-sectional study including a sample of 1.604 schoolchildren aged 4-to-6-years belonging to 21 schools from the provinces of Ciudad Real and Cuenca, Spain. We measured height, weight, body mass index (BMI), fat mass percentage (%FM), triceps skinfold thickness (TST), waist circumference (WC), systolic and diastolic BP, mean arterial pressure and pulse pressure. The estimates of prevalence of prehypertension and hypertension were 12.3% and 18.2%, respectively. In both sexes, adiposity indicators were positively and significantly associated with all BP components (p<0.001), thus schoolchildren in the higher adiposity categories had significantly higher BP levels (p<0.001). Our results show a high prevalence of high blood pressure in Spanish children. Moreover, high levels of adiposity are associated with high blood pressure in early childhood, which support that it could be related to cardiovascular risk later in life.

The objective of this study was to assess the effect of yoga, compared to physical activity on the cognitive performance in 7-9 year-old schoolchildren from a socioeconomic disadvantaged background. Two hundred (200) schoolchildren from Bangalore, India, after baseline assessment of cognitive functioning were randomly allocated to either a yoga or a physical-activity group. Cognitive functions (attention and concentration, visuo-spatial abilities, verbal ability, and abstract thinking) were assessed using an Indian adaptation of the Wechsler Intelligence Scale for Children at baseline, after 3 months of intervention, and later at a 3-month follow-up. Of the 200 subjects, 193 were assessed at 3 months after the study, and then 180 were assessed at the 3-month follow-up. There were no significant differences in cognitive performance between the two study groups (yoga versus physical activity) at postintervention, after controlling for grade levels. Improvement in the mean scores of cognitive tests following intervention varied from 0.5 (Arithmetic) to 1.4 (Coding) for the yoga group and 0.7 (Arithmetic) to 1.6 (Vocabulary) in the physical-activity group. Yoga was as effective as physical activity in improving cognitive performance in 7-9 year old schoolchildren. Further studies are needed to examine the dose-response relationship between yoga and cognitive performance.

Epstein-Barr virus infection is associated with inflammatory bowel disease, but its role as a pathogenetic or exacerbating factor remains unclear. The aim of this study was to evaluate the association between Epstein-Barr virus infection and inflammatory bowel disease, particularly in regard to exacerbation of disease activity. This was a nonrandomized crosssectional study in subgroups of patients with inflammatory bowel disease compared with a control group with noninflammatory disease. Participants were patients treated for ulcerative colitis or Crohn's disease and individuals undergoing evaluation for noninflammatory disease recruited from 2 urban adult gastrointestinal referral centers in Greece. Diagnosis of inflammatory bowel disease was based on standard clinical and endoscopic criteria. Demographic and clinical characteristics of all participants were recorded. Whole blood samples and fresh tissue samples from biopsy of intestinal sites were obtained from each participant. The presence of Epstein-Barr virus was determined by amplifying the LMP1 gene of the virus in blood and intestinal tissue samples. The study comprised 94 patients with inflammatory bowel disease (63 with ulcerative colitis and 31 with Crohn's disease) and 45 controls with noninflammatory disease. Of the 94 patients, 67 (71.3%) had disease exacerbation and 27 (28.7%) were in remission. The prevalence of Epstein-Barr virus genome was significantly higher in patients than in controls for intestinal tissue (44 patients, 46.8% vs 6 controls, 13.3%; p = 0.001), but not for whole blood (24 patients, 25.5% vs 9 controls, 20%; p = 0.3). The viral genome was found significantly more frequently in intestinal samples from patients with disease exacerbation compared with patients in remission (38 patients with exacerbation, 56.7% vs 6 patients in remission, 22.2%; p = 0.001), but no significant difference was found for whole blood (18 patients with exacerbation, 26.8% vs 6 patients in remission, 22

The aim of this study was to evaluate the association between respiratory disorders and sleep bruxism, with an evaluation of demographic/socioeconomic factors and childhood stress as confounding variables. A cross-sectional study was performed in the city of Diamantina, Brazil, with 448 randomly selected schoolchildren aged 8 to 11 years. The schoolchildren underwent an oral examination for the evaluation of bruxism. Parents/caregivers answered a questionnaire for the assessment of sleep bruxism; socioeconomic-demographic factors; and respiratory disorders, such as rhinitis, sinusitis, and bronchitis. The schoolchildren filled out the Children's Stress Scale. Poisson regression models were constructed separately for each respiratory disorder to determine prevalence ratios (PRs) and 95% confidence intervals (CIs). Sleep bruxism was more prevalent among children with rhinitis (PR = 1.45; 95%CI 1.08-1.93; p = 0.012) and sinusitis (PR = 1.58; 95%CI 1.06-2.36; p = 0.023). No significant association was found between sleep bruxism and bronchitis. A greater frequency of sleep bruxism was found among children whose mothers had a higher level of schooling and those who reported stress in the resistance/exhaustion phase. Rhinitis and sinusitis were associated with sleep bruxism. Moreover, sleep bruxism was more prevalent among children whose mothers had a higher level of schooling and those with higher degrees of stress.

To determine the prevalence of gastrointestinal helminthes and associated risk factors among schoolchildren in Tilili town, northwest Ethiopia. A cross-sectional study involving 385 schoolchildren was conducted between November 2011 to February 2012. Each student was selected using systematic random sampling method. Questionnaire and observation were used to identify socio-demographic and associated risk factors. Fresh stool samples were observed using formal-ether concentration technique. Data were analyzed using SPSS 16.0 statistical software. Four species of intestinal helminthes were identified with an overall prevalence of 44.2% (170 of 385 schoolchildren). The predominant parasites were Ascaris lumbricoides (A. lumbricoides) 153 (39.7%) and Trichuris trichiura (T. trichiura) 30 (7.8%). One hundred thirty five (35.1%) had single infections and 35 (9.2%) were infected with more than one helminthic parasites in which 32 (8.4%) were double infections and 3 (0.8%) were triple infections. Significant associations were observed between intestinal helminth infection and those of age, grade level, and school variables. Prevalence of hookworm infection was significant in children who did not wear shoes regularly (P<0.05). Intervention programs and education on personal and environmental hygiene should be implemented for the prevention and control of helminthic infections in the study area.

The seroprevalence of Trypanosoma cruzi infection among children is a sensitive indicator for assessing the effectiveness of programmes for control of Chagas disease. In this study we report the result of a cross-sectional serological survey carried out among schoolchildren living in a poor rural area in central Brazil. Eluates of blood collected on filter-paper were tested for anti-T. cruzi antibodies using immunofluorescence, haemagglutination, and enzyme-linked immunosorbent assays. The overall seroprevalence of T. cruzi infection was 7.9%, which compared with the findings of the national survey carried out in 1975-80 indicates that a twofold-to-threefold reduction in prevalence has occurred over the last 10 years. This is consistent with a reduction of transmission in the area, probably related to vector control efforts. Based on our results, the incidence of new cases was estimated to be 44 per annum in the study region. In rural areas with a scattered population, surveillance of T. cruzi transmission by serological screening of children at school entry is more practical and economical than entomological evaluation for assessing both the risk of transmission in the community and the efficacy of vector control measures. A sample size of around 1000 schoolchildren is sufficient to detect prevalences as low as 2%, and such an approach would be practical and applicable to most areas where Chagas disease is endemic.

In the article there are presented data of longitudinal study of the health of Moscow schoolchildren (426 children), followed throughout from the 1st to 9th class, inclusively. Students were annually clinically examined in the school. There was performed a comprehensive study of mental health and functional state of the organism in the process of education students in high school (over 2700 pupils of 5-9th classes). The health status of students was shown to deteriorate due to the increase of the prevalence of chronic disease, the rise in occupancy of the III-IV health groups, the decrease of the number of children referred to I and II health groups. Unfavorable trends in the health state among boys are more pronounced than in girls, while they are also characterized by lower functional capabilities of the CNS and lower resistance to the development of training fatigue. Relatively favorable stage of school ontogeny is characterized by period with reduced morbidity in children studying in 4th-6th classes. Deterioration in the health of students as a significant rate of the rise of chronic diseases morbidity is observed in 7-9th classes. Along with this, in the 7th and 9th classes there is revealed the deterioration of mental capacity and high frequency of the pronounced signs of fatigue among schoolchildren.

Retrospective studies have shown that statins decrease the rate and severity of exacerbations, the rate of hospitalization, and mortality in chronic obstructive pulmonary disease (COPD). We prospectively studied the efficacy of simvastatin in preventing exacerbations in a large, multicenter, randomized trial. We designed the Prospective Randomized Placebo-Controlled Trial of Simvastatin in the Prevention of COPD Exacerbations (STATCOPE) as a randomized, controlled trial of simvastatin (at a daily dose of 40 mg) versus placebo, with annual exacerbation rates as the primary outcome. Patients were eligible if they were 40 to 80 years of age, had COPD (defined by a forced expiratory volume in 1 second [FEV1] of less than 80% and a ratio of FEV1 to forced vital capacity of less than 70%), and had a smoking history of 10 or more pack-years, were receiving supplemental oxygen or treatment with glucocorticoids or antibiotic agents, or had had an emergency department visit or hospitalization for COPD within the past year. Patients with diabetes or cardiovascular disease and those who were taking statins or who required statins on the basis of Adult Treatment Panel III criteria were excluded. Participants were treated from 12 to 36 months at 45 centers. A total of 885 participants with COPD were enrolled for approximately 641 days; 44% of the patients were women. The patients had a mean (±SD) age of 62.2±8.4 years, an FEV1 that was 41.6±17.7% of the predicted value, and a smoking history of 50.6±27.4 pack-years. At the time of study closeout, the low-density lipoprotein cholesterol levels were lower in the simvastatin-treated patients than in those who received placebo. The mean number of exacerbations per person-year was similar in the simvastatin and placebo groups: 1.36±1.61 exacerbations and 1.39±1.73 exacerbations, respectively (P=0.54). The median number of days to the first exacerbation was also similar: 223 days (95% confidence interval [CI], 195 to 275) and

Introduction Chemokine (C-C motif) ligand 18 (CCL-18) has been shown to be elevated in chronic obstructive pulmonary disease (COPD) patients. This study primarily aimed to evaluate whether the serum CCL-18 level differentiates the frequent exacerbator COPD phenotype from infrequent exacerbators. The secondary aim was to investigate whether serum CCL-18 level is a risk factor for exacerbations requiring hospitalization. Materials and methods Clinically stable COPD patients and participants with smoking history but normal spirometry (NSp) were recruited for the study. Modified Medical Research Council Dyspnea Scale, COPD Assessment Test, spirometry, and 6-min walking test were performed. Serum CCL-18 levels were measured with a commercial ELISA Kit. Results Sixty COPD patients and 20 NSp patients were recruited. Serum CCL-18 levels were higher in COPD patients than those in NSp patients (169 vs 94 ng/mL, P<0.0001). CCL-18 level was significantly correlated with the number of exacerbations (r=0.30, P=0.026), although a difference in CCL-18 values between infrequent and frequent exacerbator COPD (168 vs 196 ng/mL) subgroups did not achieve statistical significance (P=0.09). Serum CCL-18 levels were significantly higher in COPD patients who had experienced at least one exacerbation during the previous 12 months. Overall, ROC analysis revealed that a serum CCL-18 level of 181.71 ng/mL could differentiate COPD patients with hospitalized exacerbations from those who were not hospitalized with a 88% sensitivity and 88.2% specificity (area under curve: 0.92). Serum CCL-18 level had a strong correlation with the frequency of exacerbations requiring hospitalization (r=0.68, P<0.0001) and was found to be an independent risk factor for hospitalized exacerbations in the multivariable analysis. Conclusion CCL-18 is a promising biomarker in COPD, as it is associated with frequency of exacerbations, particularly with severe COPD exacerbations requiring hospitalization, as well as

COPD exacerbation is characterized by worsening of symptoms, warranting change in treatment. Systemic and airway inflammation play roles in the pathogenesis of COPD exacerbation. We hypothesized whether increased serum inflammatory biomarkers are associated with the clinical outcomes of COPD exacerbation caused by different infectious pathogens. COPD patients with exacerbation were recruited from a hospital emergency department during 2014-2015. Serum procalcitonin (PCT) and C-reactive protein (CRP) were measured. Dyspnea, eosinopenia, consolidation, acidemia, and atrial fibrillation (DECAF) score was calculated for predicting mortality. Multiplex polymerase chain reaction was carried out for respiratory viral assay from nasopharyngeal swabs, and sputum bacterial culture was also performed. Hospital mortality, invasive mechanical ventilation requirement, and length of hospital stay (LOS) were evaluated, and their associations with clinical characteristics, DECAF score, and serum biomarkers were examined. A total of 62 COPD patients were enrolled. These patients were classified as Global Initiative for Obstructive Lung Disease (GOLD) stage 2, 3, and 4 in 12.9%, 6.4%, and 80.7% of cases, respectively. Isolated bacterial exacerbation was recovered in 30.6% of exacerbation episodes: Klebsiella pneumoniae was the most commonly identified bacteria. Viral pathogens and coinfections were noted in 9.6% and 16.1% of exacerbated patients, respectively. Influenza was the most commonly detected viral pathogen. Serum biomarkers and DECAF score for viruses, bacteria, coinfection, and noninfectious causes of exacerbations were similar. Neither DECAF score nor serum biomarkers were able to differentiate patients with and without mortality or requiring mechanical ventilation. Increased serum PCT was noted in patients with LOS ≥7 days when compared with those with LOS <7 days (0.38 ng/mL vs 0.1 ng/mL; P =0.035). Increased serum PCT is associated with longer LOS in COPD exacerbation

Iron supplementation may have adverse health effects in infants, probably through manipulation of the gut microbiome. Previous research in low-resource settings have focused primarily on anemic infants. This was a double blind, randomized, controlled trial of home fortification comparing multiple micronutrient powder (MNP) with and without iron. Six-month-old, non- or mildly anemic, predominantly-breastfed Kenyan infants in a rural malaria-endemic area were randomized to consume: (1) MNP containing 12.5 mg iron (MNP+Fe, n = 13); (2) MNP containing no iron (MNP−Fe, n = 13); or (3) Placebo (CONTROL, n = 7), from 6–9 months of age. Fecal microbiota were profiled by high-throughput bacterial 16S rRNA gene sequencing. Markers of inflammation in serum and stool samples were also measured. At baseline, the most abundant phylum was Proteobacteria (37.6% of rRNA sequences). The proteobacterial genus Escherichia was the most abundant genus across all phyla (30.1% of sequences). At the end of the intervention, the relative abundance of Escherichia significantly decreased in MNP−Fe (−16.05 ± 6.9%, p = 0.05) and CONTROL (−19.75 ± 4.5%, p = 0.01), but not in the MNP+Fe group (−6.23 ± 9%, p = 0.41). The second most abundant genus at baseline was Bifidobacterium (17.3%), the relative abundance of which significantly decreased in MNP+Fe (−6.38 ± 2.5%, p = 0.02) and CONTROL (−8.05 ± 1.46%, p = 0.01), but not in MNP-Fe (−4.27 ± 5%, p = 0.4445). Clostridium increased in MNP-Fe only (1.9 ± 0.5%, p = 0.02). No significant differences were observed in inflammation markers, except for IL-8, which decreased in CONTROL. MNP fortification over three months in non- or mildly anemic Kenyan infants can potentially alter the gut microbiome. Consistent with previous research, addition of iron to the MNP may adversely affect the colonization of potential beneficial microbes and attenuate the decrease of potential pathogens. PMID:28753958

Background & objectives A study was conducted to characterise larval habitats and to determine spatial heterogeneity of the Anopheles mosquito larvae. The study was conducted from May to June 1999 in nine villages along the Kenyan coast. Methods Aquatic habitats were sampled by use of standard dipping technique. The habitats were characterised based on size, pH, distance to the nearest house, coverage of canopy, surface debris, algae and emergent plants, turbidity, substrate, and habitat type. Results A total of 110 aquatic habitats like stream pools (n = 10); puddles (n = 65); tire tracks (n = 5); ponds (n = 5) and swamps (n = 25) were sampled in nine villages located in three districts of the Kenyan coast. A total of 7,263 Anopheles mosquito larvae were collected, 63.9% were early instars and 36.1% were late instars. Morphological identification of the III and IV instar larvae by use of microscopy yielded 90.66% (n = 2,377) Anopheles gambiae Complex, 0.88% (n = 23) An. funestus, An. coustani 7.63% (n = 200), An. rivulorum 0.42% (n = 11), An. pharoensis 0.19% (n = 5), An. swahilicus 0.08% (n = 2), An. wilsoni 0.04% (n = 1) and 0.11% (n = 3) were unidentified. A subset of the An. gambiae Complex larvae identified morphologically, was further analysed using rDNA-PCR technique resulting in 68.22% (n = 1,290) An. gambiae s.s., 7.93% (n = 150) An. arabiensis and 23.85% (n = 451) An. merus. Multiple logistic regression model showed that emergent plants (p = 0.019), and floating debris (p = 0.038) were the best predictors of An. gambiae larval abundance in these habitats. Interpretation & conclusion Habitat type, floating debris and emergent plants were found to be the key factors determining the presence of Anopheles larvae in the habitats. For effective larval control, the type of habitat should be considered and most productive habitat type be given a priority in the mosquito abatement programme. PMID:17378216

Rationale: In cystic fibrosis (CF), pulmonary exacerbations present an opportunity to define the effect of antibiotic therapy on systemic measures of inflammation. Objectives: Investigate whether plasma inflammatory proteins demonstrate and predict a clinical response to antibiotic therapy and determine which proteins are associated with measures of clinical improvement. Methods: In this multicenter study, a panel of 15 plasma proteins was measured at the onset and end of treatment for pulmonary exacerbation and at a clinically stable visit in patients with CF who were 10 years of age or older. Measurements and Main Results: Significant reductions in 10 plasma proteins were observed in 103 patients who had paired blood collections during antibiotic treatment for pulmonary exacerbations. Plasma C-reactive protein, serum amyloid A, calprotectin, and neutrophil elastase antiprotease complexes correlated most strongly with clinical measures at exacerbation onset. Reductions in C-reactive protein, serum amyloid A, IL-1ra, and haptoglobin were most associated with improvements in lung function with antibiotic therapy. Having higher IL-6, IL-8, and α1-antitrypsin (α1AT) levels at exacerbation onset were associated with an increased risk of being a nonresponder (i.e., failing to recover to baseline FEV1). Baseline IL-8, neutrophil elastase antiprotease complexes, and α1AT along with changes in several plasma proteins with antibiotic treatment, in combination with FEV1 at exacerbation onset, were predictive of being a treatment responder. Conclusions: Circulating inflammatory proteins demonstrate and predict a response to treatment of CF pulmonary exacerbations. A systemic biomarker panel could speed up drug discovery, leading to a quicker, more efficient drug development process for the CF community. PMID:25714657

Although the FACED score has demonstrated a great prognostic capacity in bronchiectasis, it does not include the number or severity of exacerbations as a separate variable, which is important in the natural history of these patients. Construction and external validation of a new index, the E-FACED, to evaluate the predictive capacity of exacerbations and mortality. The new score was constructed on the basis of the complete cohort for the construction of the original FACED score, while the external validation was undertaken with six cohorts from three countries (Brazil, Argentina, and Chile). The main outcome was the number of annual exacerbations/hospitalizations, with all-cause and respiratory-related deaths as the secondary outcomes. A statistical evaluation comprised the relative weight and ideal cut-off point for the number or severity of the exacerbations and was incorporated into the FACED score (E-FACED). The results obtained after the application of FACED and E-FACED were compared in both the cohorts. A total of 1,470 patients with bronchiectasis (819 from the construction cohorts and 651 from the external validation cohorts) were followed up for 5 years after diagnosis. The best cut-off point was at least two exacerbations in the previous year (two additional points), meaning that the E-FACED has nine points of growing severity. E-FACED presented an excellent prognostic capacity for exacerbations (areas under the receiver operating characteristic curve: 0.82 for at least two exacerbations in 1 year and 0.87 for at least one hospitalization in 1 year) that was statistically better than that of the FACED score (0.72 and 0.78, P <0.05, respectively). The predictive capacities for all-cause and respiratory mortality were 0.87 and 0.86, respectively, with both being similar to those of the FACED. E-FACED score significantly increases the FACED capacity to predict future yearly exacerbations while maintaining the score's simplicity and prognostic capacity for

While much support is found for embodied language processing in a first language (L1), evidence for embodiment in second language (L2) processing is rather sparse. In a recent study, we found support for L2 embodiment, but also an influence of L1 on L2 processing in adult learners. In the present study, we compared bilingual schoolchildren who speak German as one of their languages with monolingual German schoolchildren. We presented the German prepositions auf (on), über (above), and unter (under) in a Stroop-like task. Upward or downward responses were made depending on the font colour, resulting in compatible and incompatible trials. We found compatibility effects for all children, but in contrast to the adult sample, there were no processing differences between the children depending on the nature of their other language, suggesting that the processing of German prepositions of bilingual children is embodied in a similar way as in monolingual German children.

Oral health problems have been increasingly recognized as important factors causing a negative impact on daily performance and quality of life. The purpose of this study was to assess the impact of tooth extraction with no replacement, untreated fractured anterior teeth, malocclusion, dental restorations, and orthodontic braces on the quality of life in Nigerian schoolchildren. A total of 197 9- to 17-year-old schoolchildren completed the Oral Health Impact Profile (OHIP) index/questionnaire. Students who had tooth extraction with no replacement and untreated fractured incisors had significantly higher mean OHIP scores for functional limitations, physical pain, psychological discomfort, physical, psychological, and social disabilities, and handicaps (P<.001) when compared to other groups and the control. The mean OHIP scores of students with features of malocclusion were significantly higher for functional limitations, psychological discomfort, and psychological disability compared to the control group (P<.001). Untreated dental problems had some negative impact on the quality of life on the 7 subscales of the OHIP.

Despite strong evidence of the prevalence of food insecurity in adults and households with children in different areas of Iran, the prevalence of child-specific food insecurity in Iran and especially in Tabriz has not been evaluated. Therefore, the objective of the current study is to evaluate the prevalence of food insecurity in schoolchildren and to identify its social, demographic, and nutritional determinants in Tabriz, Iran. This cross-sectional study was conducted between April and September 2014 among 330 schoolchildren aged 7-11 years comprising 170 boys and 160 girls from ten public schools in Tabriz, Iran. Demographic and socioeconomic factors had been obtained from participants. Food security status was assessed by an eight-item U.S. Department of Agriculture (USDA) Food Security Module previously validated for use in Iran. Dietary information was obtained by a food frequency questionnaire (FFQ). In our findings, the prevalence of food insecurity among children was 30% with 29.1% being low food secure and 0.9% being very low food secure. Mean weight for age Z-score (WAZ) in the food insecure group was significantly lower than in the food secure group. The prevalence of food insecurity was more prevalent in boys (p = .006). Food insecure children had a significantly lower intake of energy, carbohydrate, protein, and meat (p < .001) and higher prevalence of wasting compared with their counterparts in the food secure group (p = .004). These results suggest a proportionally high prevalence of food insecurity in schoolchildren in Tabriz and its significant association with poor nutritional status and dietary habits. Our findings also ensures the necessity of nutritional support programs and nutritional education in Iranian low-income families to improve their overall health.

To assess body composition modifications in post-pubertal schoolchildren after practice of a physical activity program during one school year. The sample consisted of 386 students aged between 15 and 17 years and divided into two groups: the study group (SG) comprised 195 students and the control group (CG), 191. The SG was submitted to a physical activity program and the CG attended conventional physical education classes. Body composition was assessed using body mass index (BMI), percentage of body fat (%BF), fat mass (FM), and lean mass (LM). A positive effect of the physical activity program on body composition in the SG (p<0.001) was observed, as well as on the interaction time x group in all the variables analyzed in both genders. A reduction in %BF (mean of differences = -5.58%) and waist circumference (-2.33 cm), as well as an increase in LM (+2.05 kg) were observed in the SG for both genders, whereas the opposite was observed in the CG. The practice of programmed physical activity promotes significant reduction of body fat in post-pubertal schoolchildren. Copyright © 2013 Sociedade Brasileira de Pediatria.

Exacerbations of chronic obstructive pulmonary disease (COPD) lead to high morbidity and mortality. Respiratory virus infection is considered as one of the important causes of COPD exacerbations. The aim of this study was to assess the prevalence of respiratory virus infection in COPD exacerbations and to find the factors associated with susceptibility to viral infections. Furthermore, we tried to examine if COPD exacerbations caused by viral infections have more severe clinical outcomes in comparison with those with non-viral causes. We enrolled the patients with acute exacerbations of COPD who were hospitalized in a university hospital, over a 2-year period. Nasopharyngeal swabs were taken and viruses were identified by multiplex polymerase chain reaction. A total of 278 episodes of COPD exacerbations were recorded in 213 patients with COPD (number of females = 73). Among the COPD exacerbations, viral infection was detected in 78 episodes (28.1%) from 67 subjects. The most common virus was rhinovirus (38.8%), followed by respiratory syncytial virus, coronavirus, influenza A, parainfluenza, adenovirus and metapneumovirus. In multivariate regression analysis adjusting for sex, age, BMI, lung function and history of exacerbations, female subjects were found to be significantly associated with viral infections in COPD exacerbations (Odds ratio 2.58, 95%CI 1.25-5.31, P = 0.010). The severity of COPD exacerbations were not different between positive and negative viral detections. In conclusion, the prevalence of viral infection was 28.1% in the hospitalized patients with COPD exacerbations. Moreover, female subjects are at significantly higher risk for viral infections in COPD exacerbations.

Present treatment strategies to stratify exacerbation risk in patients with chronic obstructive pulmonary disease (COPD) rely on a history of two or more events in the previous year. We aimed to understand year to year variability in exacerbations and factors associated with consistent exacerbations over time. In this longitudinal, prospective analysis of exacerbations in the Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) cohort, we analysed patients aged 40-80 years with COPD for whom 3 years of prospective data were available, identified through various means including care at academic and non-academic medical centres, word of mouth, and existing patient registries. Participants were enrolled in the study between Nov 12, 2010, and July 31, 2015. We classified patients according to yearly exacerbation frequency: no exacerbations in any year; one exacerbation in every year during 3 years of follow-up; and those with inconsistent exacerbations (individuals who had both years with exacerbations and years without during the 3 years of follow-up). Participants were characterised by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) spirometric category (1-4) on the basis of post-bronchodilator FEV 1 . Stepwise logistic regression was used to compare factors associated with one or more acute exacerbations of COPD every year for 3 years versus no exacerbations in the same timeframe. Additionally, a stepwise zero-inflated negative binomial model was used to assess predictors of exacerbation count during follow-up in all patients with available data. Baseline symptom burden was assessed with the COPD assessment test. This trial is registered with ClinicalTrials.gov, number NCT01969344. 2981 patients were enrolled during the study. 1843 patients had COPD, of which 1105 patients had 3 years of complete, prospective follow-up data. 538 (49%) of 1105 patients had at least one acute exacerbation during the 3 years of follow-up, whereas

Education of schoolchildren in cardiopulmonary resuscitation (CPR) is a strategic goal for improvement of bystander CPR in society. The primary objective was to analyse the impact of CPR training on the resuscitation knowledge and self-confidence of secondary schoolchildren. In addition, independent predictors of improved CPR knowledge and self-confidence were investigated. Randomised-interventional controlled study. Four secondary schools in Germany. Four hundred and twenty-four schoolchildren aged from 14 to 18 years were included into the study. Fifty-one percent were female, and 33% had an immigrant background. The intervention group received a 90-min CPR training session, whereas controls had no intervention. Levels of knowledge and self-confidence in initiating CPR were analysed by a study questionnaire before (t0), 90 min after (t1) and 6 months after training (t2). Based on the evaluation of study questionnaires, the primary endpoint was to determine the development of resuscitation knowledge and self-confidence in initiating cardiopulmonary resuscitation at survey time-points t0, t1 and t2. Schoolchildren in the intervention group (n=207) showed a significantly higher level of knowledge (P < 0.001) and self-confidence (P < 0.001) at t1 and t2 compared with controls (n=217). Age was a predictor for long-term self-confidence [odds ratio (OR), 1.20; 95% confidence interval (95% CI), 1.02 to 1.41; P = 0.032]. The long-term benefit in the level of knowledge and self-confidence were significantly higher in native compared with immigrant schoolchildren: (OR, 1.79; 95% CI, 1.14 to 2.82; P = 0.011) and (OR, 1.67; 95% CI, 1.07 to 2.60; P = 0.024), respectively. Guideline compliant (90 min) theoretical and practical CPR training improves the level of knowledge and self-confidence in 14 to 18-year-old schoolchildren. Older schoolchildren are more likely to have increased self-confidence with respect to initiating CPR. Schoolchildren with an

Anecdotal reports suggest that certain disorders are common in African hair and may be associated with hairstyles. A cross-sectional study of 1042 schoolchildren was performed to test this hypothesis. A questionnaire was administered and scalp examinations performed, after ethics approval. Participants included 45% boys and 55% girls. The majority of boys, 72.8%, kept natural hair with frequent haircuts (within 4 weeks). The prevalence of acne (folliculitis) keloidalis nuchae (AKN) was 0.67% in the whole group and highest (4.7%) in boys in the final year of high school, all of whom had frequent haircuts. The majority of girls (78.4%) had chemically relaxed hair, which was usually combed back or tied in ponytails, vs. 8.6% of boys. Traction alopecia (TA) was significantly more common with relaxed than natural hair, with an overall prevalence of 9.4% (98 of 1042) and of 17.1% in girls, in whom it increased with age from 8.6% in the first year of school to 21.7% in the last year of high school. The proportion with TA in participants with a history of braids on natural hair was lower (22.9%), but not significantly, than among those with a history of braids on relaxed hair (32.1%). No cases of central centrifugal cicatricial alopecia were identified. We found associations between hairstyle and disease in our population of schoolchildren. AKN appears to be associated with frequently cut natural hair and TA with relaxed hair. These associations need further study for purposes of disease prevention.

Thinness is rarely highlighted or regularly monitored among children in developed countries although it may be rather frequent and pose a significant risk to children's health. We aimed to describe the prevalence of mild, moderate and severe thinness among young Serbian schoolchildren. Cross-sectional study of schoolchildren aged 6-9 years. Children were assessed for weight, height and BMI as part of the WHO European Childhood Obesity Surveillance Initiative in Serbia. Thinness grades were defined as gender- and age-specific cut-offs for BMI according to the International Obesity Task Force criteria. Serbia, September to November 2015. Students (n 4861) in grades 2 and 3 (6-9 years, 2397 girls). Overall prevalence of thinness in Serbian schoolchildren was 9·6 %. Mild thinness was clearly the largest category with a prevalence of 7·6 %, moderate thinness was present in 1·7 % of children and severe thinness was found in 0·3 % of children. OR indicated a significant risk of being thin for girls (1·44 times higher compared with boys) and children attending schools with no health-focused educational programme (1·57 times more likely to be thin than peers enrolled in schools with such programmes). In addition, OR for thinness tended to be 1·23 times higher in children living in an economically disadvantaged region of Serbia (P=0·06). A rather high prevalence of thinness highlights this malnutrition disorder as an emerging health issue that should trigger public health policies to tackle thinness, especially in girls of young age and children living in economically disadvantaged areas.

Arithmetic skill is of critical importance for academic achievement, professional success and everyday life, and childhood is the key period to acquire this skill. Neuroimaging studies have identified that left parietal regions are a key neural substrate for representing arithmetic skill. Although the relationship between functional brain activity in left parietal regions and arithmetic skill has been studied in detail, it remains unclear about the relationship between arithmetic achievement and structural properties in left inferior parietal area in schoolchildren. The current study employed a combination of voxel-based morphometry (VBM) for high-resolution T1-weighted images and fiber tracking on diffusion tensor imaging (DTI) to examine the relationship between structural properties in the inferior parietal area and arithmetic achievement in 10-year-old schoolchildren. VBM of the T1-weighted images revealed that individual differences in arithmetic scores were significantly and positively correlated with the gray matter (GM) volume in the left intraparietal sulcus (IPS). Fiber tracking analysis revealed that the forceps major, left superior longitudinal fasciculus (SLF), bilateral inferior longitudinal fasciculus (ILF) and inferior fronto-occipital fasciculus (IFOF) were the primary pathways connecting the left IPS with other brain areas. Furthermore, the regression analysis of the probabilistic pathways revealed a significant and positive correlation between the fractional anisotropy (FA) values in the left SLF, ILF and bilateral IFOF and arithmetic scores. The brain structure-behavior correlation analyses indicated that the GM volumes in the left IPS and the FA values in the tract pathways connecting left IPS were both related to children's arithmetic achievement. The present findings provide evidence that individual structural differences in the left IPS are associated with arithmetic scores in schoolchildren. PMID:24367320

The mechanism by which various classes of medication reduce COPD exacerbation risk remains unknown. We hypothesized a correlation between reduced exacerbation risk and improvement in airway patency as measured according to FEV 1 . By systematic review, COPD trials were identified that reported therapeutic changes in predose FEV 1 (dFEV 1 ) and occurrence of moderate to severe exacerbations. Using meta-regression analysis, a model was generated with dFEV 1 as the moderator variable and the absolute difference in exacerbation rate (RD), ratio of exacerbation rates (RRs), or hazard ratio (HR) as dependent variables. The analysis of RD and RR included 119,227 patients, and the HR analysis included 73,475 patients. For every 100-mL change in predose FEV 1 , the HR decreased by 21% (95% CI, 17-26; P < .001; R 2 = 0.85) and the absolute exacerbation rate decreased by 0.06 per patient per year (95% CI, 0.02-0.11; P = .009; R 2 = 0.05), which corresponded to an RR of 0.86 (95% CI, 0.81-0.91; P < .001; R 2 = 0.20). The relationship with exacerbation risk remained statistically significant across multiple subgroup analyses. A significant correlation between increased FEV 1 and lower COPD exacerbation risk suggests that airway patency is an important mechanism responsible for this effect.

Fetal alcohol syndrome (FAS) is a congenital syndrome caused by maternal alcohol consumption during pregnancy and is entirely preventable by abstinence from alcohol drinking during this time. Little is known about the prevalence of FAS and maternal alcohol consumption during pregnancy in Western countries. We present the results of FAS/partial fetal alcohol syndrome (PFAS) prevalence study and maternal characteristics in a sample of schoolchildren from a rural province of Croatia. This study involved seven elementary schools with 1,110 enrolled children attending 1st to 4th grade and their mothers. We used an active case ascertainment method with passive parental consent and Clarified IOM criteria. The investigation protocol involved maternal data collection and clinical examination of children. Out of 1,110 mothers, 917 (82.6%) answered the questionnaire. Alcohol exposure during pregnancy was admitted by 11.5%, regular drinking by 4.0% and binge drinking by 1.4% of questioned mothers. Clinical examination involved 824 (74.2%) schoolchildren and disclosed 14 (1.7%) with clinical signs of FAS and 41 (5.0%) of PFAS. The observed FAS prevalence, based on 74.2% participation rate, was 16.9, PFAS 49.7 and combined prevalence was 66.7/1,000 examined schoolchildren. This is the first FAS prevalence study based on active ascertainment among schoolchildren and pregnancy alcohol drinking analysis performed in a rural community of Croatia and Europe. High prevalence of FAS/PFAS and pregnancy alcohol consumption observed in this study revealed that FAS is serious health problem in rural regions as well as a need to develop future studies and preventive measures for pregnancy alcohol drinking and FASD.

Obesity in children has become a global epidemic with many health and social consequences that often continue into adulthood. According to the International Obesity Task Force report from 2005, Serbia has had one of the most rapidly increasing trends in the prevalence of childhood obesity during the last 10 years. The aim of the study was to estimate the prevalence of childhood obesity in a sample of schoolchildren in Belgrade and to investigate the correlation between child obesity and the presence of selected diseases. The study comprised of 854 pupils from two primary schools in Belgrade. The anthropometric data, as well as the data on the presence of selected diseases were obtained from medical records of regular health check-ups in the period from 2006-2007. The classification of childhood obesity was done according to the WHO percentiles reference data for obesity and overweight in children. Statistical analyses included chi 2 test and correlation analysis. In our sample of schoolchildren, the prevalence of obesity was 30.7%. The following diseases were present among the pupils: spinal deformities 192 (22.5%), chest wall deformities 90 (10.5%) and foot deformities 226 (26.5%). Statistically significant correlation was registered between child obesity and the presence of spinal (p=0.192; p=0.001) and foot deformities (p=0.099; p=0.049). Chest wall deformities were more frequent in the group of children with normal weight compared with the obese group (chi 2=0.206; p=0.052). Statistically significant correlation was registered between childhood obesity and the presence of hypertension (p=0.261; p=0.001). Regular physical activity was in correlation with the absence of childhood obesity (p=-0.093; p=0.055). In our sample of Belgrade schoolchildren, we detected a high prevalence of obesity. Furthermore, a significant correlation between childhood obesity and the presence of hypertension, spinal deformities and foot deformities were also observed.

Eosinophilic airway inflammation in patients with chronic obstructive pulmonary disease (COPD) is associated with exacerbations and responsivity to steroids, suggesting potential shared mechanisms with eosinophilic asthma. However, there is no consistent blood eosinophil count that has been used to define the increased exacerbation risk. We sought to investigate blood eosinophil counts associated with exacerbation risk in patients with COPD. Blood eosinophil counts and exacerbation risk were analyzed in patients with moderate-to-severe COPD by using 2 independent studies of former and current smokers with longitudinal data. The Genetic Epidemiology of COPD (COPDGene) study was analyzed for discovery (n = 1,553), and the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study was analyzed for validation (n = 1,895). A subset of the ECLIPSE study subjects were used to assess the stability of blood eosinophil counts over time. COPD exacerbation risk increased with higher eosinophil counts. An eosinophil count threshold of 300 cells/μL or greater showed adjusted incidence rate ratios for exacerbations of 1.32 in the COPDGene study (95% CI, 1.10-1.63). The cutoff of 300 cells/μL or greater was validated for prospective risk of exacerbation in the ECLIPSE study, with adjusted incidence rate ratios of 1.22 (95% CI, 1.06-1.41) using 3-year follow-up data. Stratified analysis confirmed that the increased exacerbation risk associated with an eosinophil count of 300 cells/μL or greater was driven by subjects with a history of frequent exacerbations in both the COPDGene and ECLIPSE studies. Patients with moderate-to-severe COPD and blood eosinophil counts of 300 cells/μL or greater had an increased risk exacerbations in the COPDGene study, which was prospectively validated in the ECLIPSE study.

To obtain patient-generated data relating to the management of their chronic obstructive pulmonary disease (COPD) in Primary Care before hospitalisation with exacerbation. Previous audits of COPD have shown high rates of hospital admission and readmission. There is significant interest in understanding the reasons so that useful preventative strategies may be developed. As part of the 2008 UK COPD audit, which comprised 9716 cases of COPD admission across 97% of acute units, we obtained a sample of patient-generated data to assess understanding of COPD, use of healthcare resources, access to care and self-management in Primary Care prior to hospitalisation with exacerbation. We anticipated the data would provide useful insight for directing improvement strategies. A paper-based, anonymised survey was completed by patients identified as having exacerbation by participating hospital teams. Response rate was an estimated 46%. Understanding and awareness of COPD was very variable. Patients noticed symptoms of COPD exacerbation, particularly change in sputum, for some time prior to hospitalisation but tended not to react promptly to these changes. A minority had self-care plans, many bypassed Primary Care Services and there was variable access to a named health professional or advice. Patients using home oxygen and nebulisers were at particular risk of admission. We conclude these sick patients use a lot of resources and the data suggest a need to support and educate them in the proactive management of exacerbation. There needs to be better 'exacerbation planning' so patients know how to recognise and treat flare-up but also whom to contact in the event of decline. Targetted support should be considered for the most vulnerable, particularly those using home oxygen and nebulisers, who have very high rates of hospitalisation.

As China re-establishes its health insurance system through various cooperative schemes, little is known about schoolchildren's health insurance. This paper reports findings from a study that examined schoolchildren's insurance coverage, disparities between farmer and non-farmer households, and effects of low-premium cooperative schemes on healthcare access and utilization. It also discusses barriers to sustainable enrollment and program growth. A survey of elementary school students was conducted in Pinggu, a rural/suburban district of Beijing. Statistical analyses of association and adjusted odds ratio via logistic regression were conducted to examine various aspects of health insurance. Children's health insurance coverage rose to 54% by 2005, the rates are comparable for farmers' and non-farmer's children. However, 76% of insured farmers' children were covered under a low-premium scheme protecting only major medical events, compared to 42% among insured non-farmers' children. The low-premium schemes improved parental perceptions of children's access to and affordability of healthcare, their healthcare-seeking behaviors, and overall satisfaction with healthcare, but had little impact on utilization of outpatient care. Enrolling and retaining schoolchildren in health insurance are threatened by the limited tangible value for routine care and low reimbursement rate for major medical events under the low-premium cooperative schemes. Coverage rates may be improved by offering complimentary and supplementary benefit options with flexible premiums via a multi-tier system consisting of national, regional, and commercial programs. Health insurance education by means of community outreach can reinforce positive parental perceptions, hence promoting and retaining insurance enrollment in short-term.

Research on the challenges of raising a child with autism is mostly conducted in Europe, North America and Australia, and has revealed that parents have to come to terms with living with a lifelong developmental disability. In addition, parents are faced with numerous concerns, such as caring burdens, poor prognosis, and negative public attitudes. Virtually no research has been conducted in Africa on this subject. Thirty-seven interviews and eight focus group discussions were conducted with parents of children with autism and professionals in regular contact with these parents from rural and urban counties of the Kenyan coast. The study investigated challenges faced by parents and how they cope with those challenges. A purposive-convenience sampling procedure was used in selecting the study participants. A digital recorder was used to record all the interviews and focus group discussions. Transcriptions were done in Swahili, translated into English, and then imported to the NVivo software program for content analysis. The results indicate that parents of children with autism on the Kenyan coast experience common challenges including stigma, lack of appropriate treatment, financial and caring burdens regardless of their religious and cultural backgrounds. Coping strategies applied by parents comprised problem-focused aspects that involve diet management and respite care, and emotion-focused aspects that consist of beliefs in supernatural powers, prayers and spiritual healing. This qualitative study reveals a range of challenges that could have significant impact when caring for a child with autism. Coping strategies applied by parents target the physical health of the child and the psychological wellbeing of the parent. Consideration of these outcomes is vital as they could impact the initiation of a community-based rehabilitation service delivery in rural settings where parents play an active role.

Background The prevalence of high blood pressure in children is increasing worldwide, largely, but not entirely, driven by the concurrent childhood obesity epidemic. The aims of this study were to examine the prevalence of prehypertension and hypertension in 4-to-6-year-old Spanish schoolchildren, and to evaluate the association between different blood pressure (BP) components with different adiposity indicators. Methods Cross-sectional study including a sample of 1.604 schoolchildren aged 4-to-6-years belonging to 21 schools from the provinces of Ciudad Real and Cuenca, Spain. We measured height, weight, body mass index (BMI), fat mass percentage (%FM), triceps skinfold thickness (TST), waist circumference (WC), systolic and diastolic BP, mean arterial pressure and pulse pressure. Results The estimates of prevalence of prehypertension and hypertension were 12.3% and 18.2%, respectively. In both sexes, adiposity indicators were positively and significantly associated with all BP components (p<0.001), thus schoolchildren in the higher adiposity categories had significantly higher BP levels (p<0.001). Conclusions Our results show a high prevalence of high blood pressure in Spanish children. Moreover, high levels of adiposity are associated with high blood pressure in early childhood, which support that it could be related to cardiovascular risk later in life. PMID:28141860

To investigate the relationship between Vitamin D and exacerbation in COPD patients. The PubMed database was searched for articles published from 2012 onwards using search terms related to Vitamin D and exacerbation in COPD patients. Meta-analysis, clinical trials, observational studies, and human studies were included. Non-English articles or articles with full text unavailable were excluded; a total of 15 articles were selected. The association between exacerbation frequency and Vitamin D levels in observational studies remains controversial, however, meta-analysis revealed a negative association between serum Vitamin D and exacerbation. Also, two clinical trials showed that Vitamin D3 supplementation in COPD patients reduced the risk of moderate and severe exacerbation. Vitamin D binding protein (VDBP) polymorphisms seem to affect patient exacerbation susceptibility. Few studies in literature have data related to diet, 25-hydroxyVitamin D [25(OH)D] and polymorphism in COPD exacerbation. One clinical trial indicates Vitamin D supplementation plays a role in COPD patients with hypovitaminosis D in preventing exacerbations. Further studies are needed to elucidate the role of Vitamin D in this population and to establish the best marker for Vitamin D, which patient subgroups will benefit, and the best supplement dosage without leading to toxicity.

We analyzed the association between food insecurity and dental caries in 7- to 9-yr-old schoolchildren. We performed a cross-sectional survey nested in a population-based cohort study of 203 schoolchildren. The participants lived in the urban area of a small town within the western Brazilian Amazon. Dental examinations were performed according to criteria recommended by the World Health Organization. The number of decayed deciduous and permanent teeth as a count variable was the outcome measure. Socio-economic status, food security, behavioral variables, and child nutritional status, measured by Z-score for body mass index (BMI), were investigated, and robust Poisson regression models were used. The results showed a mean (SD) of 3.63 (3.26) teeth affected by untreated caries. Approximately 80% of schoolchildren had at least one untreated decayed tooth, and nearly 60% lived in food-insecure households. Sex, household wealth index, mother's education level, and food-insecurity scores were associated with dental caries in the crude analysis. Dental caries was 1.5 times more likely to be associated with high food-insecurity scores after adjusting for socio-economic status and sex. A significant dose-response relationship was observed. In conclusion, food insecurity is highly associated with dental caries in 7- to 9-yr-old children and may be seen as a risk factor. These findings suggest that food-security policies could reduce dental caries. © 2014 Eur J Oral Sci.

Recent researches have pointed out the need to consider the functional and psychosocial dimensions of oral health, such as Oral Health-related Quality of Life (OHRQoL). The aim of this study was to investigate the influence of oral health status, socioeconomic factors and home environment of children on the four health domains of Child Perceptions Questionnaire (CPQ11-14). A cross-sectional study was conducted in Brazil with a sample of 286 schoolchildren aged 12 years and their parents. The schoolchildren were clinically examined, and participants were asked to complete the CPQ11-14, as well as a questionnaire about home environment. In addition, a questionnaire was sent to each child's parents asking them about family socioeconomic status. The chi-square test and Poisson's regression analysis were performed. After adjusting for potential confounders, variables sex, monthly family income, mothers' education showed a statistically significant association with all health domains of the CPQ11-14. The family structure and presence of bleeding impacted on emotional (p = 0.0135), and social (p = 0.0010) well-being health domain scores. Orthodontic treatment need showed a strong negative effect on functional limitations domain score (p = 0.0021). Clinical and socio-environmental factors had different impacts on domains of oral health-related quality of life, demonstrating the need to consider these conditions in planning strategies for the oral health of schoolchildren.

The objective of this study was to determine the prevalence of overweight and obesity among Brazilian schoolchildren according to gender, age and geographic region. A descriptive association study was conducted on 36,976 schoolchildren (20,914 boys and 16,062 girls aged 10 to 15 years) between 2004 and 2005 using secondary data originating from a school-based cross-sectional epidemiological survey. The cut-off body mass index proposed by the International Obesity Task Force was used as diagnostic criterion for overweight and obesity. The prevalence of overweight and obesity was 11.9% and 2.6%, respectively, with a higher proportion of overweight among girls and of obesity among boys. An association was observed between overweight, age and region, with the demonstration of higher odds ratios for overweight among children aged 10 to 13 years and children from the South, Center-West and Southeast regions. Obesity was significantly associated with gender, age and region, indicating higher odds ratios among boys, children aged 10 to 13 years and children from the South and Southeast regions. Although lower than that observed in most developed countries, the prevalence of overweight and obesity among Brazilian schoolchildren is a matter of concern. In this respect, health policies and strategies should take into account gender and age of the individuals and geographic region of the country.

Both epidemiologic characteristics and transmission mode of a varicella outbreak among schoolchildren in Shenzhen city were studied and related control measures were discussed. Case definition was established. Case-finding and face-to-face investigation were conducted, followed by analysis on distributions of time, place and persons of the outbreak. Association between possible modes of transmission and the outbreak was explored. Retrospective cohort study was carried out. The overall attack rate of this outbreak was 4.4% (122 of 2742). The attack rate among primary schoolchildren(8.3%, 118/1419)was higher than that in the middle-school children(0.3%, 4/1323). There were no statistically significant differences on the attack rates between male and female students. A total of 22 classes from the 9 grades were affected by this outbreak and the aggregation of varicella cases was found in classes. The highest attack rates was found in the students of fifth grade(23.7%), followed by from the third grade (13.4%). The main transmission mode appeared to be close personal contact. The outbreak, with four peaks of incidence, lasted 72 days. Data from the investigation suggested that the primary case was introduced into the school during military training involved by the students. Activities related to physical examination for all the schoolchildren seemed to have contributed to the spread of this disease among classes. Delayed isolation of cases appeared to be the major factor causing the spread of disease among classes. Intensive off-school activities or free community bus for children did not seem to be associated with the spreading of the disease. 52.5% (64/122) of the cases had received one-dose of varicella vaccine, with the median of onset after the vaccination as 7 years. The results demonstrated that one single-dose vaccine or long vaccination period were factors related to the insufficient immunity that causing the outbreak of disease. Varicella outbreak has been
Nutrition and educational achievement of urban primary schoolchildren in Malaysia.

The relationship between nutrition, health and educational achievement of school-age population in less developed countries has been of interest to many researchers due to the frequent observation that many children did not complete primary school and those who completed, did not do as well as children in the developed countries. Nevertheless, nutritional and health status by itself is not the only variable affecting educational achievement, since biological, psychological, socioeconomic and cultural factors could directly or indirectly affect both nutrition, health status and educational achievement. The mechanism by which health and nutrition influence educational achievement is not well established, but poor health and malnutrition in early childhood may affect cognitive abilities, necessary for learning process and consequently educational achievement. A study was conducted in Kuala Lumpur, Malaysia, to investigate the relationship between nutritional status and educational achievement among primary schoolchildren from low income households (n = 399). A high percentage of them were mild-significantly underweight (52%), stunted (47%) and wasted (36%) and increasingly overweight (6%). In general, more boys than girls were found to experience some form of malnutrition. While weight-for-height did not differ significantly according to family, child and school factors, weight-for-age and height-for-age differed significantly by gender. Also, height-for-age was significantly related to household income. This indicates that stunting may be a consequence of prolonged socioeconomic deprivation. Educational achievement was measured based on test scores for Malay language (ML), English language (EL) and mathematics (MT). While a majority of the schoolchildren obtained optimum scores (>75) for ML and MT, the majority of them had insufficient scores (<50) for EL. Children's total score (TS) for the three subjects was significantly associated with household socioeconomic

Exacerbations are a major cause of disability, hospital admissions, and increased healthcare costs in patients with chronic obstructive pulmonary disease (COPD). This study investigated the clinical outcomes of outpatients with moderate to severe exacerbated COPD and their related costs. An observational study on the outcomes of ambulatory exacerbations of COPD was conducted. The course of the exacerbation was evaluated at a follow-up visit at 4 weeks. A cost analysis that encompassed the use of healthcare resources for treatment of the exacerbation was performed. A total of 260 patients were included, with a mean age of 68.3 years and a mean FEV1 (% predicted) of 58.9 %. Twenty-two percent of patients had significant cardiovascular comorbidity. The most frequently prescribed antibiotics were moxifloxacin in 137 cases and amoxicillin-clavulanate in 50 cases. The rate of failure at 4 weeks was 12.5 %, with no differences between the two most prescribed antibiotics; however, patients treated with moxifloxacin had symptoms for 1.9 fewer days (P = 0.01). The mean cost of the exacerbation was
Patients’ experience of identifying and managing exacerbations in COPD: a qualitative study

Background: Effective self-management in chronic obstructive pulmonary disease (COPD) is crucial to reduce hospital admissions and improve outcomes for patients. This includes early detection and treatment of exacerbations by patients themselves. Aims: To explore patients’ current understanding and experience of managing and identifying COPD exacerbations at home. Methods: A qualitative, interview-based study was carried out in patients’ homes. Interviews were audio-recorded, transcribed and analysed using a grounded theory approach. Forty-four patients (17 women, 27 men; age range 55–85 years), with moderate-to-very-severe COPD, were recruited to the interview study from primary and secondary care settings in Oxford, UK, during 2012–2013. Results: Patients identified exacerbations on the basis of measurable, ‘visible’ symptoms, such as cough and sputum and ‘invisible’ symptoms, such as chest sensations and bodily knowledge. Most patients seemed to use a combination of these approaches when identifying exacerbations, according to the symptoms that had the most impact on their well-being. Patients used additional self-management strategies during an exacerbation, such as self-medication (antibiotics and steroids) and monitored their recovery. Contact with health-care professionals usually occurred when patients felt no longer able to manage themselves. Conclusions: Patients use both assessment of objective biomarkers, which are aligned with medical knowledge, and subjective symptoms based on their experience, to identify and manage exacerbations of COPD.

Antiretroviral treatment interruptions (TIs) cause suboptimal clinical outcomes. Data on TIs during social disruption are limited. We determined effects of unplanned TIs after the 2007-2008 Kenyan postelection violence on virological failure, comparing viral load (VL) outcomes in HIV-infected adults with and without conflict-induced TI. Two hundred and one patients were enrolled, median 2.2 years after conflict and 4.3 years on treatment. Eighty-eight patients experienced conflict-related TIs and 113 received continuous treatment. After adjusting for preconflict CD4, patients with TIs were more likely to have detectable VL, VL >5,000 and VL >10,000. Unplanned conflict-related TIs are associated with increased likelihood of virological failure.

Matrix metalloprotease-9 (MMP-9) plays a role in progression of cystic fibrosis, and doxycycline can reduce MMP-9 in vitro Here, we explore the effect of doxycycline during cystic fibrosis exacerbation treatment on MMP-9 related readouts and clinical end-points.This randomised, double-blind, placebo-controlled study enrolled hospitalised patients with cystic fibrosis undergoing exacerbation. In total, 20 participants were given doxycycline and 19 participants were given placebo over an 8-day period during hospitalisation. Biospecimens were collected at the beginning and the end of the study period. Primary end-points were total MMP-9 levels in the sputum and safety/tolerability. Secondary end-points included change in lung function, time to next exacerbation, and markers of MMP-9-related protease activity (active MMP-9 and TIMP-1). Nonparametric testing was used for within-group and between-group analyses.Doxycycline was well tolerated, with no treatment discontinuations or serious adverse events. Doxycycline reduced total sputum MMP-9 levels by 63.2% (p<0.05), and was also associated with a 56.5% reduction in active MMP-9 levels (p<0.05), a 1.6-fold increase in sputum TIMP-1 (p<0.05), improvement in forced expiratory volume in 1 s (p<0.05), and an increase in time to next exacerbation (p<0.01).Adjunctive use of doxycycline improved dysregulated MMP-9 levels in sputum, along with biomarkers consistent with a reduced proteolytic pulmonary environment. Improvement in clinical outcome measures suggests an important therapeutic benefit of doxycycline for individuals with cystic fibrosis. Copyright ©ERS 2017.

The effects of respiratory viral infection on the time course of chronic obstructive pulmonary disease (COPD) exacerbation were examined by monitoring changes in systemic inflammatory markers in stable COPD and at exacerbation. Eighty-three patients with COPD (mean [SD] age, 66.6 [7.1] yr, FEV(1), 1.06 [0.61] L) recorded daily peak expiratory flow rate and any increases in respiratory symptoms. Nasal samples and blood were taken for respiratory virus detection by culture, polymerase chain reaction, and serology, and plasma fibrinogen and serum interleukin-6 (IL-6) were determined at stable baseline and exacerbation. Sixty-four percent of exacerbations were associated with a cold occurring up to 18 d before exacerbation. Seventy-seven viruses (39 [58.2%] rhinoviruses) were detected in 66 (39.2%) of 168 COPD exacerbations in 53 (64%) patients. Viral exacerbations were associated with frequent exacerbators, colds with increased dyspnea, a higher total symptom count at presentation, a longer median symptom recovery period of 13 d, and a tendency toward higher plasma fibrinogen and serum IL-6 levels. Non-respiratory syncytial virus (RSV) respiratory viruses were detected in 11 (16%), and RSV in 16 (23.5%), of 68 stable COPD patients, with RSV detection associated with higher inflammatory marker levels. Respiratory virus infections are associated with more severe and frequent exacerbations, and may cause chronic infection in COPD. Prevention and early treatment of viral infections may lead to a decreased exacerbation frequency and morbidity associated with COPD.

Gastroesophageal reflux disease (GERD) is associated with different pulmonary diseases, including chronic obstructive pulmonary disease (COPD). Whether GERD is contributory to COPD severity remains unclear. This study aims to evaluate the contribution of GERD to the clinical manifestation of COPD based on ventilatory parameters and yearly clinical exacerbations. We studied 48 patients (56% females, age 66 years) with COPD. All patients underwent high-resolution manometry and esophageal pH monitoring. The patients were separated into two groups according to the presence of GERD. GERD was present in 21 (44%) patients. GERD + and GERD - groups did not differ in regard to gender, age, and body mass index. Pulmonary parameters were not different in the absence or presence of GERD. The number of yearly exacerbations was higher in patients GERD+. The severity of GERD (as measured by DeMeester score) correlated with the number of exacerbations. Our results show the following: 1) GERD does not influence pulmonary parameters and 2) GERD is associated with a higher number of annual clinical exacerbations. We believe GERD must be objectively tested in patients with COPD because the prevalence of GERD in these patients is underestimated when only symptoms are considered. GERD treatment might decrease the frequency of episodes of exacerbation.

Few consistent data are available in relation to the cognitive and neuropsychological processes involved in sluggish cognitive tempo (SCT) symptoms. The objective of this study was to determine the association of working memory and attentional networks with SCT symptoms in primary schoolchildren. The participants were schoolchildren aged 7 to 10 years ( n = 183) from primary schools in Catalonia (Spain). All the participants completed a working memory task (n-back) and an attentional network task (ANT). Their parents completed an SCT-Child Behavior Checklist self-report and a questionnaire concerning sociodemographic variables. Teachers of the participants provided information on ADHD symptoms and learning determinants. SCT symptoms were correlated with lower scores in both the n-back and ANT. In multivariate regression analysis, SCT symptoms were associated with slower hit reaction times from the ANT. Our results suggest that SCT symptoms are associated with a neuropsychological profile that is different from the classical ADHD profile and characterized by slower reaction times.

While much support is found for embodied language processing in a first language (L1), evidence for embodiment in second language (L2) processing is rather sparse. In a recent study, we found support for L2 embodiment, but also an influence of L1 on L2 processing in adult learners. In the present study, we compared bilingual schoolchildren who speak German as one of their languages with monolingual German schoolchildren. We presented the German prepositions auf (on), über (above), and unter (under) in a Stroop-like task. Upward or downward responses were made depending on the font colour, resulting in compatible and incompatible trials. We found compatibility effects for all children, but in contrast to the adult sample, there were no processing differences between the children depending on the nature of their other language, suggesting that the processing of German prepositions of bilingual children is embodied in a similar way as in monolingual German children.

In major marathon races such as the 'World Marathon Majors', female and male East African runners particularly from Ethiopia and Kenya are the fastest. However, whether this trend appears for female and male Ethiopians and Kenyans at recreational level runners (i.e. races at national level) and in shorter road races (e.g. in half-marathon races) has not been studied yet. Thus, the aim of the present study was to examine differences in the performance and the age of female and male runners from East Africa (i.e. Ethiopians and Kenyans) between half- and full marathons. Data from 508,108 athletes (125,894 female and 328,430 male half-marathoners and 10,205 female and 43,489 male marathoners) originating from 126 countries and competing between 1999 and 2014 in all road-based half-marathons and marathons held in one country (Switzerland) were analysed using Chi square (χ(2)) tests, mixed-effects regression analyses and one-way analyses of variance. In half-marathons, 48 women (0.038 %) and 63 men (0.019 %) were from Ethiopia and 80 women (0.063 %) and 134 men (0.040 %) from Kenya. In marathons, three women (0.029 %) and 15 men (0.034 %) were from Ethiopia and two women (0.019 %) and 33 men (0.075 %) from Kenya. There was no statistically significant association between the nationality of East Africans and the format of a race. In both women and men, the fastest race times in half-marathons and marathons were achieved by East African runners (p < 0.001). Ethiopian and Kenyan runners were the youngest in both sexes and formats of race (p < 0.001). In summary, women and men from Ethiopia and Kenya, despite they accounted for <0.1 % in half-marathons and marathons, achieved the fastest race times and were the youngest in both half-marathons and marathons. These findings confirmed in the case of half-marathon the trend previously observed in marathon races for a better performance and a younger age in East African runners from Ethiopia and Kenya.

The purpose of this study is to monitor the prevalence trend in overweight and obesity among Copenhagen schoolchildren from the school years 2002 to 2007. Copenhagen community health service doctors conducted routine examinations at school entry (ages 5-8 years) and exit (ages 14-16 years). Body mass index (kg/m²) of 33,245 schoolchildren was calculated. The prevalence of overweight (including obesity) and obesity was classified using the International Obesity Task Force definitions. From 2002 to 2007, although the prevalence of overweight (including obesity) in young girls decreased from 17.8 to 15.9%, the trend was non-significant. In young boys, the trend slightly decreased, and the prevalence fell from 14.0 to 11.6%. In adolescent girls, the prevalence varied considerably and increased from 22.7 to 25.4% without a discernable trend. In adolescent boys, the trend slightly increased, and the prevalence rose from 15.8 to 18.9%. There were no significant changes in the prevalence of obesity. In contrast to the preceding decades, we identified a potential stagnation in the obesity epidemic among children but a continuing increase among adolescents. It remains critical to continue monitoring and to increase preventive measures to reduce the prevalence of overweight and obesity. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.
Dietary pattern among schoolchildren with normal nutritional status in Navarre, Spain.
Durá-Travé, Teodoro; Gallinas-Victoriano, Fidel
2014-04-11
A nutrition survey was carried out (food intake registration of three consecutive school days) in a randomly selected group of 353 schoolchildren (188 males and 165 females) with normal nutritional status. The average age of the surveyed students was 10.5 years (CI 95%: 10.3-11.7). There were no significant differences between both sexes in mean values for calorie intake (males: 2072.7 ± 261.7 and females: 2060.9 ± 250.6) and intake of macronutrients, minerals and vitamins. Cereals (34%), dairy products (19%) and meats (17%) were responsible for approximately 70% of total calorie intake. Protein accounted for 20.3% of energy intake, carbohydrates for 48.8%, total fat for 30.9%, and saturated fat for 12.6%. Cholesterol intake was excessive and over two-thirds of protein intake was from animal sources. The mean intakes of calcium, iodine and Vitamins A, D and E were below recommended levels. The dietary patterns of the schoolchildren with normal nutritional status differed from the Mediterranean diet. Intakes of meat were too high and dairy products and cereals consumption was relatively limited; while that of vegetables; legumes; fruits and fish were insufficient; leading to excessive protein and fat intake from animal sources and insufficient mineral (calcium and iodine) and Vitamins A; D and E intake.

Background Surprisingly little is known about the geographical overlap between malaria and other tropical diseases, including helminth infections. This is despite the potential public health importance of co-infection and synergistic opportunities for control. Methods Statistical models are presented that predict the large-scale distribution of hookworm in sub-Saharan Africa (SSA), based on the relationship between prevalence of infection among schoolchildren and remotely sensed environmental variables. Using a climate-based spatial model of the transmission potential for Plasmodium falciparum malaria, adjusted for urbanization, the spatial congruence of populations at coincident risk of infection is determined. Results The model of hookworm indicates that the infection is widespread throughout Africa and that, of the 179.3 million school-aged children who live on the continent, 50.0 (95% CI: 48.9–51.1) million (27.9% of total population) are infected with hookworm and 45.1 (95% CI: 43.9–46) million are estimated to be at risk of coincident infection. Conclusion Malaria and hookworm infection are widespread throughout SSA and over a quarter of school-aged children in sub-Saharan Africa appear to be at risk of coincident infection and thus at enhanced risk of clinical disease. The results suggest that the control of parasitic helminths and of malaria in school children could be viewed as essential co-contributors to promoting the health of schoolchildren. PMID:17083720
The Role of the Microbiome in Exacerbations of Chronic Lung Diseases
Dickson, Robert P.; Martinez, Fernando J.; Huffnagle, Gary B.
2014-01-01
Summary Culture-independent microbiological techniques have revealed a previously unappreciated complexity to the bacterial microbiome of the respiratory tract, forcing reconsideration of the interactions between host, bacteria and the pathogenesis of exacerbations of chronic lung disease. The composition of the lung microbiome is determined by microbial immigration, elimination, and the relative growth rates of its members; all of these change dramatically in chronic lung disease and further during exacerbations. Exacerbations lack key features of bacterial infections, including increased bacterial burden and decreased community diversity. We propose instead that exacerbations are occasions of respiratory dysbiosis: a disordered respiratory microbial ecosystem with negative effects on host biology. Respiratory dysbiosis provokes a dysregulated host immune response, which in turn alters microbial growth conditions in patient airways, further promoting dysbiosis and perpetuating a coupled cycle of inflammation and disordered microbiota. Differences in baseline respiratory microbiota may help explain the “frequent-exacerbator” phenotype observed across multiple disease states, and may provide novel targets for therapeutic intervention.

Although the presence of pneumothorax is generally considered an absolute contraindication to air travel, reports on pneumomediastinum after air travel are extremely rare. Moreover, to the best of our knowledge, exacerbation of existing pneumomediastinum after commercial air travel has never been reported. We report on a case of a patient (the first case that we are aware of) who suffered exacerbation of pneumomediastinum after commercial air travel. This patient, with confirmed pneumomediastinum before air travel, flew to our city for medical care without being warned about exacerbation by the local hospital or airlines. Obvious exacerbation of pneumomediastinum and subcutaneous emphysema was noticed after the travel. Subsequently, a diagnosis of amyopathic dermatomyositis with interstitial lung disease and pneumomediastinum was made. The patient died despite treatment with corticosteroid, cyclophosphamide and intravenous immunoglobulin. This report discusses this rare condition and offers suggestions regarding air travel for patients with presence of pneumomediastinum at the time of flight.

To assess the prevalence of trachoma in schoolchildren of Botucatu/ SP-Brazil and its spatial distribution. Cross-sectional study in children aged from 7 to 14 years, who attended elementary schools in Botucatu/SP in November/2005. The sample size was estimated in 2,092 children, considering the 11.2% historic prevalence of trachoma, accepting an estimation error of 10% and confidence level of 95%. The sample was random, weighted and increased by 20%, because of the possible occurrence of losses. The total number of children examined was 2,692. The diagnosis was clinical, based on WHO guidelines. For the evaluation of spatial data, the CartaLinx program (v1.2) was used, and the school demand sectors digitized according to the planning divisions of the Department of Education. The data were statistically analyzed, and the analysis of the spatial structure of events calculated using the Geode program. The prevalence of trachoma in schoolchildren of Botucatu was 2.9% and there were cases of follicular trachoma. The exploratory spatial analysis failed to reject the null hypothesis of randomness (R= -0.45, p>0.05), with no significant demand sectors. The analysis for the Thiessen polygons also showed that the overall pattern was random (I= -0.07, p=0.49). However, local indicators pointed to a group of low-low type for a polygon to the north of the urban area. The prevalence of trachoma in schoolchildren in Botucatu was 2.9%. The analysis of the spatial distribution did not reveal areas of greater clustering of cases. Although the overall pattern of the disease does not reproduce the socio-economic conditions of the population, the lower prevalence of trachoma was found in areas of lower social vulnerability.

Many medical, nutrition, and education professionals have long suspected that poor diet impairs the academic performance of Western schoolchildren; academic performance often improves after improved diet. However, others have suggested that such academic gains may be due to psychologic effects rather than nutrition. To resolve this issue, two independent research teams conducted randomized trials in which children were given placebos or low-dose vitamin-mineral tablets designed to raise nutrient intake to the equivalent of a well-balanced diet. Both teams reported significantly greater gains in nonverbal intelligence among the supplemented groups. The findings were important because of the apparent inadequacy of diet they revealed and the magnitude of the potential for increased intelligence. However, none of the ten subsequent replications, or the two original trials, were without limitations leaving this issue in controversy. To determine if schoolchildren who consume low-dose vitamin-mineral tablets will have a significantly larger increase in nonverbal intelligence than children who consume placebos in a study that overcomes the primary criticisms directed at the previous 12 controlled trials. A double-blind, placebo-controlled trial using stratified randomization within each teacher's class based on preintervention nonverbal intelligence. Two "working class," primarily Hispanic, elementary schools in Phoenix, Arizona, participated in the study. Slightly more than half the teachers in each school distributed the tablets daily to 245 schoolchildren aged 6 to 12 years. Daily vitamin-mineral supplementation at 50% of the U.S. daily recommended allowance (RDA) for 3 months versus placebo. Post-test nonverbal IQ, as measured by the Wechsler Intelligence Scale for Children-Revised (WISC-R), while controlling for pretest nonverbal IQ as a covariate. FOUR MAIN RESULTS: First, a significant difference of 2.5 IQ points (95% CI: 1.85-3.15) was found between 125 children

Antibiotic Residues in Milk from Three Popular Kenyan Milk Vending Machines.
Kosgey, Amos; Shitandi, Anakalo; Marion, Jason W
2018-05-01
Milk vending machines (MVMs) are growing in popularity in Kenya and worldwide. Milk vending machines dispense varying quantities of locally sourced, pasteurized milk. The Kenya Dairy Board has a regulatory framework, but surveillance is weak because of several factors. Milk vending machines' milk is not routinely screened for antibiotics, thereby increasing potential for antibiotic misuse. To investigate, a total of 80 milk samples from four commercial providers ( N = 25), street vendors ( N = 21), and three MVMs ( N = 34) were collected and screened in Eldoret, Kenya. Antibiotic residue surveillance occurred during December 2016 and January 2017 using Idexx SNAP ® tests for tetracyclines, sulfamethazine, beta-lactams, and gentamicin. Overall, 24% of MVM samples and 24% of street vendor samples were presumably positive for at least one antibiotic. No commercial samples were positive. Research into cost-effective screening methods and increased monitoring by food safety agencies are needed to uphold hazard analysis and critical control point for improving antibiotic stewardship throughout the Kenyan private dairy industry.

Many patients with an exacerbation of chronic obstructive pulmonary disease (COPD) are treated with antibiotics. However, the value of antibiotics remains uncertain as systematic reviews and clinical trials have shown conflicting results. To assess the effects of antibiotics in the management of acute COPD exacerbations on treatment failure as observed between seven days and one month after treatment initiation (primary outcome) and on other patient-important outcomes (mortality, adverse events, length of hospital stay). We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and other electronically available databases up to September 2012. Randomised controlled trials (RCTs) in people with acute COPD exacerbations comparing antibiotic therapy and placebo with a follow-up of at least seven days. Two review authors independently screened references and extracted data from trial reports. We kept the three groups of outpatients, inpatients and patients admitted to the intensive care unit (ICU) separate for benefit outcomes and mortality because we considered them to be clinically too different to be summarised in one group. We considered outpatients to have a mild to moderate exacerbation, inpatients to have a severe exacerbation and ICU patients to have a very severe exacerbation. Where outcomes or study details were not reported we requested missing data from the authors of the primary studies. We calculated pooled risk ratios (RR) for treatment failure, Peto odds ratios (OR) for rare events (mortality and adverse events) and weighted mean differences (MD) for continuous outcomes using fixed-effect models. We used GRADE to assess the quality of the evidence. Sixteen trials with 2068 participants were included. In outpatients (mild to moderate exacerbations), there was evidence of low quality that antibiotics did statistically significantly reduce the risk for treatment failure between seven days and one month after treatment

Introduction The literature presents studies correlating chronic obstructive pulmonary disease to dysphagia and suggesting that the aspiration laryngeal phenomenon related to changes in the pharyngeal phase contributes significantly to the exacerbation of symptoms of lung disease. Objectives This study aimed to conduct a literature review to identify the relation between dysphagia and exacerbations of chronic obstructive pulmonary disease. Data Synthesis We found 21 studies and included 19 in this review. The few studies that related to the subject agreed that the presence of dysphagia, due to lack of coordination between swallowing and breathing, may be one of the triggering factors of chronic obstructive pulmonary disease exacerbation. Conclusions The review noted that there is a relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, identified by studies demonstrating that the difficulties associated with swallowing may lead to exacerbation of the disease. There was difficulty in comparing studies by their methodological differences. More research is needed to clarify the relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, making it possible to develop multiprofessional treatment strategies for these patients, catered to specific needs due to the systemic manifestations of the disease.

Kenyan who "discovered the cure for AIDS" taken to court.
1996-06-01
In Nairobi, Kenya, Professor Obel, the Kenyan scientist who produced two drugs that he claimed would cure acquired immunodeficiency syndrome (AIDS), is being taken to court, and Pearl Omega, one of the drugs, has been banned by the Ministry of Health. Initially, Obel may have gained support in the ministry because of his friendship with Phillip Mbithi, former Chief Secretary in the office of the president, and others. Obel claimed in March to have found a cure for AIDS; he was lambasted by scientists. On April 24, Assistant Health Minister Basil Criticos told parliament that the government was to carry out clinical trials of the drug and that Obel was to be encouraged. On May 2, Health Minister Joshua Angatia stated that Pearl Omega was a herbal concoction whose efficacy had never scientifically been proven. The Society of People with AIDS in Kenya has taken Obel to court; some patients who had taken part in trials of Kemron, Obel's other miracle drug, had been told by the professor that they had become HIV-negative.

Background The use of food frequency questionnaires (FFQs) has become increasingly important in epidemiologic studies. During the past few decades, a wide variety of nutritional studies have used the semiquantitative FFQ as a tool for assessing and evaluating dietary intake. One of the main concerns in a dietary analysis is the validity of the collected dietary data. Methods This paper discusses several methodological and statistical issues related to the validation of a semiquantitative FFQ. This questionnaire was used to assess the nutritional habits of schoolchildren in western Greece. For validation purposes, we selected 200 schoolchildren and contacted their respective parents. We evaluated the relative validity of 400 FFQs (200 children's FFQs and 200 parents' FFQs). Results The correlations between the children's and the parents' questionnaire responses showed that the questionnaire we designed was appropriate for fulfilling the purposes of our study and in ranking subjects according to food group intake. Conclusion Our study shows that the semiquantitative FFQ provides a reasonably reliable measure of dietary intake and corroborates the relative validity of our questionnaire. PMID:19196469

Even in western developed countries, the probability of survival after out-of-hospital cardiac arrest (OHCA) is only 6-10%. In order to improve survival after OHCA, early initiation of cardiopulmonary resuscitation (CPR) by laypersons is essential. Introduction of CPR training in schoolchildren seems to be effective to increase lay-CPR rates. The objective of the present investigation was to elucidate educational aspects of teaching schoolchildren in CPR and to summarize campaigns related to a comprehensive establishment of lay-CPR worldwide. A literature research in PubMed was performed, the cutoff date was 27 February 2017. Overall, 192 abstracts were analyzed; 51 articles were considered relevant and included in the manuscript. An additional keyword research in Google revealed >230,000 entries, and 20 of those were included in the present manuscript. A minimum age of 12-13 years is required to achieve a comparable quality of CPR to adult basic life support (BLS). Key issues are (i) the correct detection of a cardiac arrest, (ii) a correctly performed call for help, (iii) thoracic compressions and (iv) if applicable, the initiation of adequate mouth-to-mouth ventilation. Practical training showed a significantly higher CPR quality compared to theoretical training only or to the use of instruction or online videos only. Worldwide implementation of a 2-h BLS training per year in children from the age of 12 or younger is recommended by the "Kids Save Lives"- statement since 2015. In Germany, implementation at the level of the federal states has progressed to different degrees.

We tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD). Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms. Individuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P < 0.001), and more of them had a history of respiratory infections (6.8 vs 1.4%, P < 0.001) than individuals with COPD but without gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3-5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6-2.7, P = 0.63). Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly. © 2014 Asian Pacific Society of Respirology.

No epidemiological survey of the prevalence of Enterobius vermicularis infection in Miaoli County and Taichung County has been conducted. This epidemiological survey was performed to describe the profile of E. vermicularis infection in schoolchildren in Miaoli County and Taichung County. The first part of this study was conducted between November 2005 and February 2006 in Miaoli County. 44,071 primary schoolchildren from 18 districts were examined by 2 consecutive-day adhesive cellophane perianal swabs to estimate the infection rate. The second part was performed between October 2006 and January 2007 in Taichung County. 24,382 primary schoolchildren from 14 districts were examined. In Miaoli County, the infection rate was 2.39% (1054/44,071). The infection rate was highest in the Taian (6.69%; 20/299), Shytarn (4.49%; 11/245), and Dahu townships (3.6%; 40/1111). In Taichung County, the infection rate was 2.95% (720/24,382). The infection rate was highest in the Da-an (5.46%; 26/476) and Heping townships (4.48%; 9/201). The infection rate for a family with > or =3 children was significantly higher than that for a family with < or =2 children (p = 0.007). The frequency of washing linen and cleaning bedclothes significantly affected the infection rate of enterobiasis (p < 0.01). The efficacy rate for mebendazole was 96%, with no difference between 1 and 2 doses. The number of children per family and the frequency of washing linen and cleaning bedclothes were the most important factors for transmission of pinworm infection among the groups surveyed.

Patients allergic to pollen have been known to become more symptomatic during pollen season compared with the nonpollen season. However, there are few studies regarding whether higher exposure to pollen might increase the prevalence of allergic diseases. An ecological analysis was conducted to evaluate whether pollen exposure is associated with the prevalence of allergic diseases in schoolchildren. Pollen count data of Japanese cedar (Cryptomeria japonica) and Japanese cypress (Chamaecyparis obtusa), which are the major pollen allergens in Japan, were obtained from each prefecture. The prevalence of allergic diseases in schoolchildren in each prefecture was based on a nationwide cross-sectional survey using the International Study of Asthma and Allergies in Childhood questionnaire. After omitting three prefectures where pollen data were not available, data of 44 prefectures were analysed. The prevalence of allergic rhinoconjunctivitis in children aged 6-7 years was positively associated with both cedar and cypress pollen counts (P = 0.01, both), whereas the prevalence of allergic rhinoconjunctivitis in children aged 13-14 years was positively associated with only cypress pollen counts (P = 0.003). Furthermore, the prevalence of asthma was positively associated with cedar pollen counts in 6- to 7-year-old children (P = 0.003) but not cypress pollen counts in either age group. There are ecological associations between pollen counts and the prevalence of allergic diseases in Japanese schoolchildren. Further studies are needed to determine whether the difference between the effects of cedar and cypress pollens is attributable to pollen counts or allergenicity. © 2013 John Wiley & Sons A/S.

To test the goodness of fit of a Motivation-Ability-Opportunity model (MAO-model) to evaluate the observed variance in Mexican schoolchildren's preferences to eat fruit and daily fruit intake; also to evaluate the factorial invariance across the gender and type of population (urban and semi-urban) in which children reside. A model with seven constructs was designed from a validated questionnaire to assess preferences, cognitive abilities, attitude, modelling, perceived barriers, accessibility at school, accessibility at home, and fruit intake frequency. The instrument was administered in a representative sample of 1434 schoolchildren of 5th and 6th grade of primary school in a cross-sectional and ex post fact study conducted in 2013 in six cities of the State of Chihuahua, Mexico. The goodness of fit indexes was adequate for the MAO-model and explained 39% of the variance in preference to eat fruit. The structure of the model showed very good factor structure stability and the dimensions of the scale were equivalent in the different samples analyzed. The model analyzed with structural equation modeling showed a parsimonious model that can be used to explain the variation in fruit intake of 10 to 12 year old Mexican schoolchildren. The structure of the model was strictly invariant in the different samples analyzed and showed evidence of cross validation. Finally, implications about the modification model to fit data from scholar settings and guidelines for future research are discussed. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

This cross-sectional study assessed associations between nutrition and dental caries in permanent dentition and identified oral hygiene indicators among older children aged 12-14 years in primary schools in Thailand. The study was comprised of 862 schoolchildren from five provinces representing five regions of Thailand, from both rural and urban areas, including Bangkok. The dental hygeine status was assessed by evaluating for decayed teeth, missing teeth due to decay, and filled teeth index (DMFT index). Weight and height were measured to evaluate the nutritional status; hygiene practices assessed by interview. The results show a negative relationship between nutritional status and the DMFT index, which increased when the nutritional status decreased (Spearman's rho correlation = -0.140, p < 0.001). The results from multiple logistic regression analysis showed normal weight and thin schoolchildren were more likely to have a DMFT of at least 1 by 1.94 times (OR = 1.94; 95%CI = 1.25-3.00, p = 0.004) and 2.22 times (OR = 2.22; 95%CI = 1.20-4.09, p = 0.001), respectively, compared to overweight and obese children. Normal and thin schoolchildren had a higher risk for dental caries than overweight and obese children aged 12-14 years in Thailand. School health promotion activities should emphasize eating habit improvement in order to reduce the incidence of caries.

Giardia duodenalis infection is highly prevalent and a cause of underweight in pre-school children in rural Rwanda. The present study aimed at assessing the age-pattern of Giardia infection and its manifestation in older children, i.e., during school age. Stool samples were collected from 622 schoolchildren at two schools in the Huye district of southern Rwanda (rural, 301; urban, 321) and subjected to G. duodenalis specific PCR assays. Clinical and anthropometric data, socio-economic status and factors potentially associated with G. duodenalis infection were assessed. Of the 622 children (mean age, 10.4 years), 35.7% were infected with G. duodenalis (rural, 43.9%; urban, 28.0%; P<0.0001). Only few indicators of low socio-economic status were found to be associated with infection. In rural but not urban schoolchildren, infection prevalence declined significantly with age. G. duodenalis infection more than doubled the odds of stunting in both rural (adjusted OR, 2.35 (95%CI, 1.25-4.41)) and urban children (adjusted OR, 2.27 (95%CI, 1.01-5.09)). In the study area of rural southern Rwanda, G. duodenalis prevalence among children declined throughout school-age. The data suggest that while lacking overt clinical manifestation at high endemicity, G. duodenalis infection is a common cause of stunting in schoolchildren. Copyright © 2015 Elsevier B.V.

Skin cancer and other adverse health effects result from excess solar ultraviolet radiation exposure. Sun protective practices are important interventions for skin cancer prevention, particularly when implemented early in life. Several international studies have assessed children's sun-related knowledge, attitudes and behaviours in school settings but never before in Southern Africa, where multiethnic populations exist. The purpose of this study is to describe the sun-related knowledge, attitudes and behaviours as self-reported by South African primary schoolchildren and consider the roles of sex and skin type. A randomly selected sample of 707 schoolchildren from 24 government, urban schools in all nine provinces of South Africa were surveyed regarding their sun-related knowledge, attitudes and behaviours. Approximately 56% of students reported experience of sunburn last summer and 59% stated that they had got a suntan. Many students (64.5%) believed that one could protect oneself from getting skin cancer by avoiding getting sunburnt. Other means reported to do so by the students were to use sunscreen (65.4%), stay out of the summer sun (48.0%), cover up with clothing (45.5%) and eat the right foods (38.0%). Only about a quarter of the students (22.4%) wrongly agreed that it is safe to get sunburnt once or twice a year. Few students (8.7%) agreed that they like to have a suntan because they feel healthier and agreed that they think a suntan makes them feel more attractive to others (17.3%). Few also agreed that most of their friends (16.1%) and family (14.2%) think that a suntan is a good thing. Children reporting to have white/light brown skin (69.4%) were more likely to agree that they used sunscreen to protect themselves from getting sunburnt compared with children having brown/dark brown/black skin (54.8%) (P = 0.0005). South African schoolchildren at urban government schools do have some knowledge about sun protection, and they do have some positive sun

Hospitalisations for severe exacerbations of chronic obstructive pulmonary disease are associated with significant physical and psychological consequences including an increase in symptom severity, severe reductions in physical activity, a deleterious effect on skeletal muscle, impaired exercise tolerance/ability to self-care, decline in quality of life, and increased anxiety and depression. As these consequences are potentially amenable to exercise training, there is a clear rationale for pulmonary rehabilitation in the peri/post-exacerbation setting. Although a 2011 Cochrane review was overwhelmingly positive, subsequent trials have shown less benefit and real-life observational studies have revealed poor acceptability. Qualitative studies have demonstrated that the patient experience is a determining factor while the presence of comorbidities may influence referral, adherence and response to pulmonary rehabilitation. Systematic reviews of less supervised interventions, such as self-management, have shown limited benefits in the post-exacerbation setting. The recent update of the Cochrane review of peri-exacerbation pulmonary rehabilitation showed that benefits were associated with the “comprehensive” nature of the intervention (the number of sessions received, the intensity of exercise training and education delivered, and the degree of supervision) but implementation is demanding. The challenge is to develop interventions that are deliverable and acceptable around the time of an acute exacerbation but also deliver the desired clinical impact. PMID:27730157

Traumatic dental injury (TDI) is an important public dental health problem among schoolchildren. The aim of the study was to investigate the relationship between TDIs, obesity, and other possible associated factors like gender, overjet, lip coverage, parents' education level and family income among 12-year old Jordanian schoolchildren. A cross-sectional population-based study examined a total of 1015 schoolchildren attending 34 schools randomly selected from urban and rural areas of Amman-the capital city of Jordan. The epidemiological classification adopted by WHO and modified by Andreasen et al. was used to classify TDIs. Obesity was defined according to the international cut-off points of body mass index for boys and girls between 2 and 20 years old. The prevalence of TDIs was 16.3%. Enamel fracture was the most common type of TDIs (65%). Neither parents' education level nor family income had a significant effect on TDI occurrence (P > 0.05). Results of multiple logistic regression showed that TDIs were significantly more prevalent among males (OR = 1.42, CI; 1.01-2.01, P < 0.05), and children with inadequate lip coverage (OR = 1.95, CI; 1.35-2.81, P < 0.05). The relationship between TDIs and obesity was not statistically significant (P > 0.05). Being a male with inadequate lip coverage was associated with higher probability of having a TDI. Obesity had no significant effect on the occurrence of TDIs.

To analyze the prevalence and symptoms of asthma in students of the Brazilian Amazon municipality of Alta Floresta-MT. Cross-sectional study on the prevalence of asthma in 6 and 7 year-old children and 13 to 14 year-old adolescents, using the Study of Asthma and Allergies in Childhood - ISAAC method, phase I in 2007. Students who answered affirmatively question 2 - "presence of wheezing in the past 12 months" were considered asthmatic. Of the total 2,071 students, 1,072 (51.7%) were children and 999 (48.3%) were teenagers. The prevalence of asthma was 21.4% among schoolchildren, and 12.4% among adolescents (chi2 = 29.29; rho = 0.00). Children presented a higher prevalence than adolescents of the following asthma symptoms: wheezing sometime in life (49.9%), wheezing in the past 12 months (21.4%), 1 to 3 wheezing attacks in the past 12 months (16.4%), and dry cough at night (38.2%). Regarding physician-diagnosed asthma, no difference was observed between the two age groups, with a prevalence of around 6.0%. Male schoolchildren presented a higher prevalence of asthma, physician-diagnosed asthma and four or more wheezing episodes in the past 12 months (rho < 0.05). Male adolescents presented the highest prevalence of strong wheezing affecting speech (rho < 0.05). Alta Floresta presents one of the highest prevalences of asthma in Latin America among schoolchildren in the 6 and 7 year-old age group.

Among patients with chronic obstructive pulmonary disease (COPD), the frequency and severity of past exacerbations potentiates future events. The impact of current therapies on exacerbation frequency and severity in patients with different exacerbation risks is not well known. A post hoc analysis of patients at low (≤1 exacerbation [oral steroids/antibiotics requirement] and no COPD-related hospitalization in the year preceding trial entry) or high (≥2 exacerbations [oral steroids/antibiotics requirement] or ≥1 COPD-related hospitalization[s] in the year preceding trial entry) exacerbation risk, from the Prevention of Exacerbations with Tiotropium in Chronic Obstructive Pulmonary Disease (POET-COPD(®)) database. Compared with salmeterol, tiotropium significantly increased time to first COPD exacerbation (hazard ratio 0.84; 95% confidence interval [CI] 0.76-0.92; p = 0.0002) and reduced the number of COPD exacerbations (rate ratio 0.90; 95% CI 0.81-0.99; p = 0.0383) in patients at high exacerbation risk. With treatment, the risk of remaining in the high-risk exacerbator subgroup was statistically lower with tiotropium versus salmeterol (risk ratio [RR] 0.89; 95% CI 0.80-1.00; p = 0.0478). For low-risk patients, time to first COPD exacerbation and number of COPD exacerbations were numerically lower with tiotropium versus salmeterol. With treatment, the risk of transitioning from a low to a high exacerbation risk was lower with tiotropium versus salmeterol (RR 0.87; 95% CI 0.71-1.07; p = 0.1968). This analysis confirms the higher efficacy of tiotropium versus salmeterol in prolonging time to first COPD exacerbation and reducing number of exacerbations in patients both at low and high exacerbation risk.

Background Prescriber disagreement is among the reasons for poor adherence to COPD treatment guidelines; it is yet not clear whether this leads to adverse outcomes. We tested whether undertreatment according to the original Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines led to increased exacerbations. Methods Records of 878 patients with spirometrically confirmed COPD who were followed from 2005 to 2010 at one Veterans Administration (VA) Medical Center were analyzed. Analysis of variance was performed to assess differences in exacerbation rates between severity groups. Logistic regression analysis was performed to assess the relationship between noncompliance with guidelines and exacerbation rates. Findings About 19% were appropriately treated by guidelines; 14% overtreated, 44% under-treated, and in 23% treatment did not follow any guideline. Logistic regression revealed a strong inverse relationship between undertreatment and exacerbation rate when severity of obstruction was held constant. Exacerbations per year by GOLD stage were significantly different from each other: mild 0.15, moderate 0.27, severe 0.38, very severe 0.72, and substantially fewer than previously reported. Interpretation The guidelines were largely not followed. Undertreatment predominated but, contrary to expectations, was associated with fewer exacerbations. Thus, clinicians were likely advancing therapy primarily based upon exacerbation rates as was subsequently recommended in revised GOLD and other more recent guidelines. In retrospect, a substantial lack of prescriber adherence to treatment guidelines may have been a signal that they required re-evaluation. This is likely to be a general principle regarding therapeutic guidelines. The identification of fewer exacerbations in this cohort than has been generally reported probably reflects the comprehensive nature of the VA system, which is more likely to identify relatively asymptomatic (ie, nonexacerbating) COPD

Purpose: To test the hypothesis—given the increasing emphasis on quantitative computed tomographic (CT) phenotypes of chronic obstructive pulmonary disease (COPD)—that a relationship exists between COPD exacerbation frequency and quantitative CT measures of emphysema and airway disease. Materials and Methods: This research protocol was approved by the institutional review board of each participating institution, and all participants provided written informed consent. One thousand two subjects who were enrolled in the COPDGene Study and met the GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria for COPD with quantitative CT analysis were included. Total lung emphysema percentage was measured by using the attenuation mask technique with a −950-HU threshold. An automated program measured the mean wall thickness and mean wall area percentage in six segmental bronchi. The frequency of COPD exacerbation in the prior year was determined by using a questionnaire. Statistical analysis was performed to examine the relationship of exacerbation frequency with lung function and quantitative CT measurements. Results: In a multivariate analysis adjusted for lung function, bronchial wall thickness and total lung emphysema percentage were associated with COPD exacerbation frequency. Each 1-mm increase in bronchial wall thickness was associated with a 1.84-fold increase in annual exacerbation rate (P = .004). For patients with 35% or greater total emphysema, each 5% increase in emphysema was associated with a 1.18-fold increase in this rate (P = .047). Conclusion: Greater lung emphysema and airway wall thickness were associated with COPD exacerbations, independent of the severity of airflow obstruction. Quantitative CT can help identify subgroups of patients with COPD who experience exacerbations for targeted research and therapy development for individual phenotypes. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10

Objective To explore parents’ and professionals’ perceived causes and treatment of Autism Spectrum Disorders (ASD) on the Kenyan Coast. Methods In-depth interviews and focus group discussions using guiding questions were utilized in data collection. One hundred and three participants, who included parents of children with ASD, special needs teachers, clinicians, and social workers from diverse cultural background, participated in this study. The interviews and focus groups were recorded, transcribed verbatim and then translated to English. Themes were generated using content analysis. Results Preternatural causes were mentioned and included evil spirits, witchcraft, and curses. Biomedical causes comprised infections, drug abuse, birth complications, malnutrition, and genetic related problems. Treatment varied from traditional and spiritual healing to modern treatment in health facilities, and included consultations with traditional healers, offering prayers to God, and visits to hospitals. Conclusions The results suggest that regardless of cultural backgrounds, people on the Kenyan Coast have similar views on perceived causes and treatment of ASD. These findings provide valuable conceptual understanding for professionals when planning and implementing community based rehabilitation interventions targeting children with ASD within a local context.

The role of antibiotics in treating mild or moderate exacerbations in patients with acute chronic obstructive pulmonary disease (COPD) is unclear. The aims were to: (i) describe patient characteristics associated with acute exacerbations amongst a representative COPD population, (ii) explore the relationship between COPD severity and outcomes amongst patients with exacerbations, and (iii) quantify variability by general practice in prescribing of antibiotics for COPD exacerbations. A cohort of 62,747 patients with COPD was identified from primary care general practices (GP) in England, and linked to hospital admission and death certificate data. Exacerbation cases were matched to three controls and characteristics compared using conditional logistic regression. Outcomes were compared using incidence rates and Cox regression, stratified by disease severity. Variability of prescribing at the GP level was evaluated graphically and by using multilevel models. COPD severity was found to be associated with exacerbation and subsequent mortality (very severe vs. mild, odds ratio for exacerbation 2.12 [95%CI 19.5-2.32]), hazard ratio for mortality 2.14 [95%CI 1.59-2.88]). Whilst 61% of exacerbation cases were prescribed antibiotics, this proportion varied considerably between GP practices (interquartile range, 48-73%). This variation is greater than can be explained by patient characteristics alone. There is significant variability between GP practices in the prescribing of antibiotics to COPD patients experiencing exacerbations. Combined with a lack of evidence on the effects of treatment, this supports the need and opportunity for a large scale pragmatic randomised trial of the prescribing of antibiotics for COPD patients with exacerbations, in order to clarify their effectiveness and long term outcomes whilst ensuring the representativeness of subjects.

Over the past 20 years, numerous studies have investigated the ecology and behaviour of malaria vectors and Plasmodium falciparum malaria transmission on the coast of Kenya. Substantial progress has been made to control vector populations and reduce high malaria prevalence and severe disease. The goal of this paper was to examine trends over the past 20 years in Anopheles species composition, density, blood-feeding behaviour, and P. falciparum sporozoite transmission along the coast of Kenya. Using data collected from 1990 to 2010, vector density, species composition, blood-feeding patterns, and malaria transmission intensity was examined along the Kenyan coast. Mosquitoes were identified to species, based on morphological characteristics and DNA extracted from Anopheles gambiae for amplification. Using negative binomial generalized estimating equations, mosquito abundance over the period were modelled while adjusting for season. A multiple logistic regression model was used to analyse the sporozoite rates. Results show that in some areas along the Kenyan coast, Anopheles arabiensis and Anopheles merus have replaced An. gambiae sensu stricto (s.s.) and Anopheles funestus as the major mosquito species. Further, there has been a shift from human to animal feeding for both An. gambiae sensu lato (s.l.) (99% to 16%) and An. funestus (100% to 3%), and P. falciparum sporozoite rates have significantly declined over the last 20 years, with the lowest sporozoite rates being observed in 2007 (0.19%) and 2008 (0.34%). There has been, on average, a significant reduction in the abundance of An. gambiae s.l. over the years (IRR = 0.94, 95% CI 0.90-0.98), with the density standing at low levels of an average 0.006 mosquitoes/house in the year 2010. Reductions in the densities of the major malaria vectors and a shift from human to animal feeding have contributed to the decreased burden of malaria along the Kenyan coast. Vector species composition remains heterogeneous but in

Acute exacerbations in patients with chronic bronchitis are a leading cause of hospitalizations and death. Bacteria contribute significantly to such exacerbations. The aim of this review was to explore the potential role of investigational antibiotics in the treatment of these episodes. Areas covered: The available literature in PubMed database, in websites related to investigational drugs and in websites of the producing companies has been searched. The in vitro activity against pathogens involved in acute exacerbations of chronic bronchitis and the pharmacokinetic profile of antibiotics currently under development were taken into consideration for inclusion in the review. Expert opinion: Several novel antimicrobial agents have completed preclinical and Phase I studies and were well-tolerated. Further investigation is mandatory in order to evaluate their future in treatment of chronic bronchitis exacerbations and discover potential advantages compared to already approved antimicrobials.

The occurrence of neck, shoulder and low back complaints in relation to schoolbag carriage and other potential risk factors were investigated in a cross-sectional study of 586 Iranian schoolchildren aged 12-14 years. The average load carried by schoolchildren was 2.8 kg. Neck, shoulder and low back complaints during the preceding month were reported by 35.3%, 26.1% and 33% of the students, respectively. Gender was an independent factor predicting musculoskeletal symptoms in schoolchildren. Girls were more likely than boys to suffer from neck, shoulder and low back complaints, although there was no significant difference between genders in terms of schoolbag carriage variables. The findings suggest that the recommended weight limit for schoolbag carriage may need to differ between boys and girls. The associations between schoolbag variables and reported symptoms are also discussed. The results provide evidence that the current weight limit should consider a broader combination of factors that influence the use of schoolbags.

This study investigates the association between acceptance of intimate partner violence (IPV) and reported IPV victimization among Kenyan women, taking into consideration select sociocultural factors that may also influence acceptance of IPV. Data from a nationally representative, cross-sectional, household survey conducted between November 2008 and February 2009 in Kenya were analyzed. Hierarchical multiple regression was conducted to estimate the effect of select sociodemographic characteristics and reported IPV victimization on acceptance of IPV. The results showed that while both sociodemographic characteristics and reported IPV victimization were significantly associated with IPV acceptance, sociocultural factors had a greater impact. Programs aimed at empowering women and culturally competent IPV prevention strategies may be the key elements to reducing IPV. © The Author(s) 2014.

Background Antiretroviral treatment interruptions (TIs) cause suboptimal clinical outcomes. Data on TIs during social disruption are limited. Methods We determined effects of unplanned TIs after the 2007–2008 Kenyan postelection violence on virological failure, comparing viral load (VL) outcomes in HIV-infected adults with and without conflict-induced TI. Results Two hundred and one patients were enrolled, median 2.2 years after conflict and 4.3 years on treatment. Eighty-eight patients experienced conflict-related TIs and 113 received continuous treatment. After adjusting for preconflict CD4, patients with TIs were more likely to have detectable VL, VL >5,000 and VL >10,000. Conclusions Unplanned conflict-related TIs are associated with increased likelihood of virological failure. PMID:24047971

Exacerbations are a clinical characteristic of chronic obstructive pulmonary disease (COPD). The objective of the study was to estimate the resource use and costs associated with COPD exacerbations Observational study performed by retrospective review of patient clinical charts of a Hospital and 6 associated Primary Care Centers. COPD patients >40years old who were followed-up during 2010-2011, and who fulfilled inclusion/exclusion criteria were included in the study. Healthcare resource use and costs associated to COPD exacerbations (moderate/severe) were estimated. Healthcare resource use, loss of productivity and costs associated to the follow-up of COPD patients (with/without exacerbations) were also estimated. regression model and ANCOVA, P<.05. A total of 1,210patients were included in the study, of whom 51.2% experienced an exacerbation, and with an average of 4exacerbations/patient. Presence of exacerbations was associated with age, COPD severity, presence of comorbidities, and time from diagnosis. The average healthcare cost of an exacerbation was €481 (moderate: €375; severe: €863). Patients who experienced an exacerbation had a higher resource use and costs (P<.001). Thus, the follow-up cost of patients without exacerbations was €1,392 versus €3,175 for patients with exacerbations. The presence of exacerbations in COPD patients was associated with an increase in resource use and associated costs. Copyright © 2013 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

The present study aimed to investigate the distribution of total serum immunoglobulin E (IgE) levels in Korean schoolchildren and to evaluate its utility in the prediction of atopy and allergic diseases. A nationwide, cross-sectional survey was conducted in first grade students from randomly selected elementary and middle schools. Total IgE levels were measured by ImmunoCAP. Skin prick tests were performed for 18 common inhalant allergens to determine the presence of atopy. Children aged 12–13 years and parents of children aged 6–7 years were asked to complete questionnaire assessing allergic diseases. The cut-off levels of total IgE were determined by analyzing receiver operating characteristic curves. The median total IgE level was 86.7 kU/L (range: 1.5–4,523.1) in 3,753 children aged 6–7 years and 94.7 kU/L (range: 1.5–3,000.0) in 3,930 children aged 12–13 years. Total IgE concentrations were higher in children with atopy or allergic diseases than in those without (all P < 0.001). At the cut-off value of 127.7 kU/L, sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were 67.1%, 75.4%, 65.4%, and 76.7%, respectively, in elementary schoolchildren. At the cut-off value of 63.0 kU/L, sensitivity, specificity, PPV, and NPV were 81.9%, 66.6%, 75.0%, and 75.1%, respectively, in middle schoolchildren. PPV and NPV were ≥ 70% when cut-offs of 258.8 kU/L and 38.4 kU/L were used for the diagnosis of atopy in 6–7 year-olds and 12–13 year-olds, respectively. This nationwide population-based study provided the first normal reference ranges of total IgE in Korean schoolchildren. PMID:28378554

The research on industrial food animal production (IFAP) and asthma exacerbations in the United States has relied on small sample sizes and/or self-reported outcomes. We assessed associations of proximity to large-scale and densely stocked swine and dairy/veal IFAP with three types of asthma exacerbations: hospitalizations, emergency encounters, and oral corticosteroid (OCS) medication orders from Geisinger Clinic in Pennsylvania. We used a diagnosis code ( International Classification of Diseases, 9th Revision, Clinical Modification code 493.x) and medication orders from electronic health records to identify these exacerbations among asthma patients ( n = 35,269) from 2005-2012. We compared residential proximity to swine or dairy/veal IFAP (dichotomized as <3 miles (4.8 km) or ≥3 miles) among asthma patients with and without exacerbations and estimated odds ratios using multilevel logistic regression. In adjusted models, proximity to IFAP was associated (odds ratio (95% confidence interval)) with OCS orders (1.11 (1.04-1.19)) and hospitalizations (1.29 (1.15-1.46)), but not emergency encounters (1.12 (0.91-1.37)). This study contributes to growing evidence that IFAP may impact health, in this case clinically-documented asthma exacerbations. No prior study has evaluated the association of IFAP and clinically-documented asthma exacerbations in the United States.

Childhood obesity has increased to epidemic levels and is considered a public health problem due to its association with a number of metabolic abnormalities, which are being detected at earlier stages of life. The objective was to evaluate the association between the presence of subclinical metabolic abnormalities (SMA) and obesity in a sample of pre-pubertal Mexican schoolchildren. Children of both sexes and 6 to 13 years old were questioned for signs of puberty, underwent anthropometric measurement and had their Body Mass Index (BMI) calculated. Two groups were formed: those with obesity (case group) and those with normal weight paired by age and chosen randomly (control group). Fasting insulin, glucose and cholesterol were measured. 92 children were included, 46 in each group, mean age 9.9 and 9.5 years old, respectively (p = 0.97). A higher frequency of hyperinsulinism was found in the case group: Fasting insulin > 15 mU/ml, 75% vs. 21% (case group vs. control group, respectively); fasting glucose to insulin ratio < 6, 72% vs. 24%; HOMA IR > 2.7, 83% vs. 14%; and decrease in QUICKI (< 0.3), 80% vs. 19% (p = 0.000). Hypercholesterolemia was 25% vs. 15% (p = 0.22), impaired fasting glucose 28% vs. 8% (p = 0.01), and family history of diabetes mellitus (DM) 35% vs. 9% (OR = 5.6; 95% CI = 1.5-22.2; p = 0.002). In this sample of Mexican schoolchildren, obesity was associated to a higher frequency of SMA, such as hyperinsulinism and impaired fasting glucose, and to a family history of DM.

Inhalant use by children leads to poor performance in school and has been observed to precede substance use later in life. There is paucity of data on inhalant use among school children in India, particularly in the Northeast region of the country. We determined the prevalence and documented inhalant use characteristics among schoolchildren in the Northeast region of India. This cross sectional study was conducted in six states in the Northeast region of India. Schoolchildren between eighth and eleventh standards from the capital areas of the states were included in the study. Data were collected using a questionnaire. Analysis was done using descriptive statistics and Chi-square test. Of the 4074 enrolled students, data from 3943 students who responded to the inhalant use question were analyzed. Mean age was 14.8 ± 1.2 years and 51.2% of participants were male. The proportion of students who had ever used inhalants (ever user) was 18.8% and adhesive/glue was the inhalant misused by most of the students. A higher proportion of males than females were ever users (P ≤ 0.001) and the most common place of use was at home (33.1%). Being in the presence of an older person using an inhalant or tobacco was found to be associated with use of inhalants among students. Nearly one-fifth of the students had used inhalants and nearly half used inhalants in the past month. Sensitization of the parents and school authorities to the problem, as well as preventive and curative services, should be considered.

Vitamin D insufficiency (a serum 25(OH)D <30 ng/ml) has been associated with severe asthma exacerbations, but this could be explained by underlying racial ancestry or disease severity. Little is known about vitamin D and asthma in Puerto Ricans. To examine whether vitamin D insufficiency is associated with severe asthma exacerbations in Puerto Rican children, independently of racial ancestry, atopy, and time outdoors. A cross-sectional study was conducted of 560 children ages 6-14 years with (n = 287) and without (n = 273) asthma in San Juan, Puerto Rico. We measured plasma vitamin D and estimated the percentage of African racial ancestry among participants using genome-wide genotypic data. We tested whether vitamin D insufficiency is associated with severe asthma exacerbations, lung function, or atopy (greater than or equal to one positive IgE to allergens) using logistic or linear regression. Multivariate models were adjusted for African ancestry, time outdoors, atopy, and other covariates. Vitamin D insufficiency was common in children with (44%) and without (47%) asthma. In multivariate analyses, vitamin D insufficiency was associated with higher odds of greater than or equal to one severe asthma exacerbation in the prior year (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.5-4.9; P = 0.001) and atopy, and a lower FEV(1)/FVC in cases. After stratification by atopy, the magnitude of the association between vitamin D insufficiency and severe exacerbations was greater in nonatopic (OR, 6.2; 95% CI, 2-21.6; P = 0.002) than in atopic (OR, 2; 95% CI, 1-4.1; P = 0.04) cases. Vitamin D insufficiency is associated with severe asthma exacerbations in Puerto Rican children, independently of racial ancestry, atopy, or markers of disease severity or control.

Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could help better understand the pathophysiologic mechanisms involved in exacerbations, establish different strategies of treatment, and improve the process of care and patient prognosis. The objective of this study was to identify subtypes of ECOPD patients attending emergency departments using clinical variables and to validate the results using several outcomes. We evaluated data collected as part of the IRYSS-COPD prospective cohort study conducted in 16 hospitals in Spain. Variables collected from ECOPD patients attending one of the emergency departments included arterial blood gases, presence of comorbidities, previous COPD treatment, baseline severity of COPD, and previous hospitalizations for ECOPD. Patient subtypes were identified by combining results from multiple correspondence analysis and cluster analysis. Results were validated using key outcomes of ECOPD evolution. Four ECOPD subtypes were identified based on the severity of the current exacerbation and general health status (largely a function of comorbidities): subtype A (n = 934), neither high comorbidity nor severe exacerbation; subtype B (n = 682), moderate comorbidities; subtype C (n = 562), severe comorbidities related to mortality; and subtype D (n = 309), very severe process of exacerbation, significantly related to mortality and admission to an intensive care unit. Subtype D experienced the highest rate of mortality, admission to an intensive care unit and need for noninvasive mechanical ventilation, followed by subtype C. Subtypes A and B were primarily related to other serious complications. Hospitalization rate was more than 50% for all the subtypes, although significantly higher for subtypes C and D than for subtypes A and B. These results could help identify

Objective To determine whether surgical intervention prevents recurrent acute exacerbations in chronic pancreatitis (CP). Summary Background Data The primary goal of surgical intervention in the treatment of CP has been relief of chronic unrelenting abdominal pain. A subset of patients with CP have intermittent acute exacerbations, often with increasing frequency and often unrelated to ongoing ethanol abuse. Little data exist regarding the effectiveness of surgery to prevent acute attacks. Methods From 1985 to 1999, all patients identified with a diagnosis of CP were recruited to participate in an ongoing program of serial clinic visits and functional and clinical evaluations. Patients were offered surgery using standard criteria. Data were gathered regarding ethanol abuse, pain, narcotic use, and recurrent acute exacerbations requiring hospital admission before and after surgery. Patients were broadly categorized as having severe unrelenting pain alone (group 1), severe pain with intermittent acute exacerbations (group 2), and intermittent acute exacerbations only (group 3). Results Two hundred fifty-nine patients were recruited. One hundred eighty-five patients underwent 199 surgical procedures (124 modified Puestow procedure [LPJ], 29 distal pancreatectomies [DP], and 46 pancreatic head resections [PHR; 14 performed after failure of LPJ]). There were no deaths. The complication rate was 4% for LPJ, 15% for DP, and 27% for PHR. Ethanol abuse was causative in 238 patients (92%). Mean follow-up was 81 months. There were 104 patients in group 1 (86 who underwent surgery), 71 patients in group 2 (64 who underwent surgery), and 84 in group 3 (49 who underwent surgery). No patient without surgery had spontaneous resolution of symptoms. Postoperative pain relief (freedom from narcotic analgesics) was achieved in 153 of 185 patients (83%) overall: 106 of 124 (86%) for LPJ, 19 of 29 (67%) for DP, and 42 of 46 (91%) for PHR. The mean rate of acute exacerbations was 6.3

Introduction. Aerobic exercise performed after hospital discharge for exacerbated COPD patients is already recommended to improve respiratory and skeletal muscle strength, increase tolerance to activity, and reduce the sensation of dyspnea. Previous studies have shown that anaerobic activity can clinically benefit patients hospitalized with exacerbated COPD. However, there is little information on the feasibility and safety of aerobic physical activity performed by patients with exacerbated COPD during hospitalization. Objective. To evaluate the effects of aerobic exercise on vital signs in hospitalized patients with exacerbated COPD. Patients and Methods. Eleven COPD patients (63% female, FEV1: 34.2 ± 13.9% and age: 65 ± 11 years) agreed to participate. Aerobic exercise was initiated 72 hours after admission on a treadmill; speed was obtained from the distance covered in a 6-minute walk test (6MWT). Vital signs were assessed before and after exercise. Results. During the activity systolic blood pressure increased from 125.2 ± 13.6 to 135.8 ± 15.0 mmHg (p = 0.004) and respiratory rate from 20.9 ± 4.4 to 24.2 ± 4.5 rpm (p = 0.008) and pulse oximetry (SpO2) decreased from 93.8 ± 2.3 to 88.5 ± 5.7% (p < 0.001). Aerobic activity was considered intense, heart rate ranged from 99.2 ± 11.5 to 119.1 ± 11.1 bpm at the end of exercise (p = 0.092), and patients reached on average 76% of maximum heart rate. Conclusion. Aerobic exercise conducted after 72 hours of hospitalization in patients with exacerbated COPD appears to be safe. PMID:28265180
Effects of peer victimization in schools and perceived social support on adolescent well-being.
Rigby, K
2000-02-01
It has been suggested that the mental health of schoolchildren can be undermined by repeated bullying at school and further exacerbated by having inadequate social support. To evaluate this claim, the General Health Questionnaire (GHQ) was administered anonymously to 845 adolescent schoolchildren attending coeducational secondary schools in South Australia, together with measures of the extent to which each reported being bullied at school and the social support available to them. Multiple regression analyses indicated that for both sexes frequent peer victimization and low social support contributed significantly and independently to relatively poor mental health.

Background Decreased but measurable serum IgA levels (≤70 mg/dL) have been associated with risk for infections in some populations, but are unstudied in COPD. This study tested the hypothesis that subnormal serum IgA levels would be associated with exacerbation risk in COPD. Methods Data were analyzed from 1,049 COPD participants from the observational cohort study SPIROMICS (535 (51%) women; mean age 66.1 (SD 7.8), 338 (32%) current smokers) who had baseline serum IgA measured using the Myriad RBM biomarker discovery platform. Exacerbation data was collected prospectively (mean 944.3 (SD 281.3) days), and adjusted linear, logistic and zero-inflated negative binomial regressions were performed. Results Mean IgA was 269.1 mg/dL (SD 150.9). One individual had deficient levels of serum IgA (<7 mg/dL) and 25 (2.4%) had IgA level ≤70 mg/dL. Participants with IgA ≤70 mg/dL were younger (62 vs. 66 years, p = 0.01) but otherwise similar to those with higher IgA. In adjusted models, IgA ≤70 mg/dL was associated with higher exacerbation incidence rates (IRR 1.71, 95% CI 1.01–2.87, p = 0.044) and greater risk for any severe exacerbation (OR 2.99, 95% CI 1.30–6.94, p = 0.010). In adjusted models among those in the lowest decile (<120 mg/dL), each 10 mg/dL decrement in IgA (analyzed continuously) was associated with more exacerbations during follow-up (β 0.24, 95% CI 0.017–0.46, p = 0.035). Conclusions Subnormal serum IgA levels were associated with increased risk for acute exacerbations, supporting mildly impaired IgA levels as a contributing factor in COPD morbidity. Additionally, a dose-response relationship between lower serum IgA and number of exacerbations was found among individuals with serum IgA in the lowest decile, further supporting the link between serum IgA and exacerbation risk. Future COPD studies should more comprehensively characterize immune status to define the clinical relevance of these findings and their potential for therapeutic correction

Background The role of antibiotics in treating mild or moderate exacerbations in patients with acute chronic obstructive pulmonary disease (COPD) is unclear. The aims were to: (i) describe patient characteristics associated with acute exacerbations amongst a representative COPD population, (ii) explore the relationship between COPD severity and outcomes amongst patients with exacerbations, and (iii) quantify variability by general practice in prescribing of antibiotics for COPD exacerbations. Method A cohort of 62,747 patients with COPD was identified from primary care general practices (GP) in England, and linked to hospital admission and death certificate data. Exacerbation cases were matched to three controls and characteristics compared using conditional logistic regression. Outcomes were compared using incidence rates and Cox regression, stratified by disease severity. Variability of prescribing at the GP level was evaluated graphically and by using multilevel models. Results COPD severity was found to be associated with exacerbation and subsequent mortality (very severe vs. mild, odds ratio for exacerbation 2.12 [95%CI 19.5–2.32]), hazard ratio for mortality 2.14 [95%CI 1.59–2.88]). Whilst 61% of exacerbation cases were prescribed antibiotics, this proportion varied considerably between GP practices (interquartile range, 48–73%). This variation is greater than can be explained by patient characteristics alone. Conclusions There is significant variability between GP practices in the prescribing of antibiotics to COPD patients experiencing exacerbations. Combined with a lack of evidence on the effects of treatment, this supports the need and opportunity for a large scale pragmatic randomised trial of the prescribing of antibiotics for COPD patients with exacerbations, in order to clarify their effectiveness and long term outcomes whilst ensuring the representativeness of subjects.

Complicated high myopia is one of the leading causes responsible for the disablement in the children associated with visual impairment especially when it is combined with other pathological conditions and abnormalities among which are disorders of the musculoskeletal system. In the present study, we for the first time examined visually impaired schoolchildren (n=44) who suffered from high myopia complications making use of the computed optical topographer for the evaluation of the state of their vertebral column. The control group consisted of 60 children attending a secondary school. The study revealed various deformations of the musculoskeletal system including scoliosis, misalignment of the pelvis, kyphosis, hyperlordosis, torsion, platypodia, deformation of the lower extremities and the chest. These deformations were more pronounced in the visually impaired schoolchildren in comparison with the children of the same age comprising the control group (p<0,05). It is concluded that the assessment of the state of the vertebral column with the use of the apparatus yields an important information for the elaboration and application of a series of measures for the timely provision of medical assistance needed for the comprehensive rehabilitation of the visually impaired schoolchildren presenting with high myopia complications.

Cash transfer programs have the potential to prevent the spread of HIV, particularly among adolescents. One mechanism through which these programs may work is by influencing the characteristics of the people adolescents choose as sex partners. We examined the four-year impact of a Kenyan cash transfer program on partner age, partner enrollment in school, and transactional sex-based relationships among 684 adolescents. We found no significant impact of the program on partner characteristics overall, though estimates varied widely by gender, age, schooling, and economic status. Results highlight the importance of context in exploring the potential HIV preventive effects of cash transfers.

Abstract To identify a predictive value for the exacerbation status of chronic obstructive pulmonary disease (COPD) subjects, we evaluated the relationship between pulmonary vascular measurements on chest CT and severe COPD exacerbation. Six hundred three subjects enrolled in the COPDGene population were included and divided into nonexacerbator (n = 313) and severe exacerbator (n = 290) groups, based on whether they had an emergency room visit and/or hospitalization for COPD exacerbation. We measured the diameter of the main pulmonary artery (MPA) and ascending aorta (AA) at 2 different sites of the MPA (the tubular midportion and bifurcation) on both axial images and multiplanar reconstructions. Using multiple logistic regression analyses, we evaluated the relationship between each CT-measured pulmonary vasculature and exacerbation status. Axial and multiplanar MPA to AA diameter ratios (PA:AA ratios) at the tubular midportion and the axial PA:AA ratios at the bifurcation indicated significant association with severe exacerbation. The strongest association was found with the axial PA:mean AA ratio at the bifurcation (adjusted odds ratio [OR] = 12.53, 95% confidence interval [CI] = 2.35–66.74, P = .003) and the axial PA:major AA ratio at the tubular midportion (adjusted OR = 10.72, 95% CI = 1.99–57.86, P = .006). No differences were observed in the MPA diameter. Receiver operating characteristic analysis of these variables indicates that they may serve as a good predictive value for severe exacerbation (area under the curve, 0.77–0.78). The range of cut-off value for PA:AA ratio was 0.8 to 0.87. CT-measured PA:AA ratios at either the bifurcation or the tubular site, measured either on axial or multiplanar images, are useful for identification of the risk of severe exacerbation, and consequently can be helpful in guiding the management of COPD. Although CT measurement was used at the level of pulmonary bifurcation in previous

To identify a predictive value for the exacerbation status of chronic obstructive pulmonary disease (COPD) subjects, we evaluated the relationship between pulmonary vascular measurements on chest CT and severe COPD exacerbation.Six hundred three subjects enrolled in the COPDGene population were included and divided into nonexacerbator (n = 313) and severe exacerbator (n = 290) groups, based on whether they had an emergency room visit and/or hospitalization for COPD exacerbation. We measured the diameter of the main pulmonary artery (MPA) and ascending aorta (AA) at 2 different sites of the MPA (the tubular midportion and bifurcation) on both axial images and multiplanar reconstructions. Using multiple logistic regression analyses, we evaluated the relationship between each CT-measured pulmonary vasculature and exacerbation status.Axial and multiplanar MPA to AA diameter ratios (PA:AA ratios) at the tubular midportion and the axial PA:AA ratios at the bifurcation indicated significant association with severe exacerbation. The strongest association was found with the axial PA:mean AA ratio at the bifurcation (adjusted odds ratio [OR] = 12.53, 95% confidence interval [CI] = 2.35-66.74, P = .003) and the axial PA:major AA ratio at the tubular midportion (adjusted OR = 10.72, 95% CI = 1.99-57.86, P = .006). No differences were observed in the MPA diameter. Receiver operating characteristic analysis of these variables indicates that they may serve as a good predictive value for severe exacerbation (area under the curve, 0.77-0.78). The range of cut-off value for PA:AA ratio was 0.8 to 0.87.CT-measured PA:AA ratios at either the bifurcation or the tubular site, measured either on axial or multiplanar images, are useful for identification of the risk of severe exacerbation, and consequently can be helpful in guiding the management of COPD. Although CT measurement was used at the level of pulmonary bifurcation in previous studies, we suggest

Chronic Obstructive Pulmonary Disease is defined by a limitation of airflow. This disease is characterized by exacerbations that threaten the patient's life and worsens his prognosis. Moreover, COPD patients are different according to many parameters that define different phenotypes. Characteristics of exacerbations may depend on these phenotypes according to few recent studies. To determine the characteristics and the prognosis of the exacerbations in each phenotype of COPD patients phenotype in Tunisia. Retrospective study including 153 male patients hospitalized for COPD exacerbation from January 2009 to June 2012. Patients were classified into 4 phenotypes according to Burgel's classification. Patients were divided into four phenotypes: phenotype (PH)1: (n=68), PH2: (n=33), PH3: (n=25) and PH4: (n=27). Mean age for PH1, 2, 3 and 4 was: 61, 74, 56 and 72 years. The number of exacerbations per year was higher in PH1. Dyspnea was more important in PH1 and 4. Hypercapnia on admission was higher in PH4. Non invasive ventilation and transfer to resuscitation unit were more frequently mandatory in PH3 and 4. Death occurred 2% of PH1 and 5% of PH4. Hospitalization duration was more important in PH4. COPD patients are heterogenous and belong to different phenotypes. The characteristics of the exacerbations and their prognosis widely differ according to these different groups. In Tunisia, it seems that patients who had moderate respiratory functional tests impairment are the lowest responders to treatment with a higher frequency of resuscitation unit transfer.
