The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”.
In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definiti...on of wheeze was assessed. Predictors of a correct definition were determined and the potential impact of incorrect answers on prevalence estimates from the survey was assessed.
Current wheeze was reported by 13.2% of children. Overall, 83.5% of parents correctly identified “whistling or squeaking” as the definition of wheeze; the proportion was higher for parents reporting wheezy children (90.4%). Frequent attacks of reported wheeze (adjusted odds ratio (OR) 3.0), maternal history of asthma (OR 1.5) and maternal education (OR 1.5) were significantly associated with a correct answer, while the converse was found for South Asian ethnicity (OR 0.6), first language not English (OR 0.6) and living in a deprived neighbourhood (OR 0.6).
In summary, the present study showed that misunderstanding could lead to an important bias in assessing the prevalence of wheeze, resulting in an underestimation in children from South Asian and deprived family backgrounds. Prevalence estimates for the most severe categories of wheeze might be less affected by this bias and questionnaire surveys on wheeze should incorporate measures of parents' understanding of the term wheeze.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory ...light medbox">samples were collected and analyzed in the laboratory of Instituto Nacional de Investigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

In 2014, the Ministry of Health (MOH) in Malawi conducted a nationwide assessment of emergency obstetric and newborn care (EmONC) services. This cross-sectional facility-based survey used 10 data collection modules. Data collection began on 23rd September 2014 and concluded on 17th October 2014, in ...all 28 districts. Facilities in both the public and private sector (for-profit and not-for-profit) were included. Since the focus of the assessment was obstetric and newborn care, health facilities that did not offer maternal and newborn health (MNH) services were not selected. In all districts, a census of all hospitals and a 60 percent random sample of health centres that ought to have performed deliveries in the previous year yielded a total of 365 facilities: 87 hospitals and 278 health centres. All these facilities were visited during the assessment. During analysis, weighting procedures were applied to extrapolate results to the district and national level, representing all 87 hospitals and 464 health centres. Such weighting was necessary as a stratified random sample of health centres was taken and weighting applied to all indicators and presentations that have health facility as a unit of measurement. Case reviews and provider’s interviews, on the other hand, are not weighted as their sampling strategy is based on convenience.

The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Paying for performance (P4P) provides financial incentives for providers to increase the use and quality of care. P4P can affect health care by providing incentives for providers to put more effort into specific activities, and by increasing the amount of resources available to finance the delivery ...of services. This paper evaluates the impact of P4P on the use and quality of prenatal, institutional delivery, and child preventive care using data produced from a prospective quasi-experimental evaluation nested into the national rollout of P4P in Rwanda. Treatment facilities were enrolled in the P4P scheme in 2006 and comparison facilities were enrolled two years later. The incentive effect is isolated from the resource effect by increasing comparison facilities’ input-based budgets by the average P4P payments to the treatment facilities. The data were collected from 166 facilities and a random sample of 2158 households. P4P had a large and significant positive impact on institutional deliveries and preventive care visits by young children, and improved quality of prenatal care. The authors find no effect on the number of prenatal care visits or on immunization rates. P4P had the greatest effect on those services that had the highest payment rates and needed the lowest provider effort. P4P financial performance incentives can improve both the use of and the quality of health services. Because the analysis isolates the incentive effect from the resource effect in P4P, the results indicate that an equal amount of financial resources without the incentives would not have achieved the same gain in outcomes.

DIAGNOSING PTSD IN CHILDHOOD | The following literature review addresses the developmental and domain-specific consequences of previous and current diagnostic criteria for posttraumatic stress disorder (PTSD) in pre-adolescent children. PTSD was introduced in 1980 to capture extreme responses follow...ing a traumatic event. I analyze the evolution of the disorder’s diagnostic criteria toward a more developmentally conscious structure. I also examine instances in which these criteria lack developmental consistency: (1) preschool PTSD is the only diagnostic subtype despite the fact that childhood development also differentiates traumatic expressions in older children from adolescents and adults; and (2) many of the PTSD epidemiological data that have been reanalyzed under the most recent (DSM-5) typology only refer to adolescent and adult samples although many researchers have
demonstrated that developmental alterations to DSM-IV and DSM-IV-TR criteria produce significantly higher prevalence rates in children.

agencies working toward developing trauma-informed
approaches to service delivery. It describes how common
traumatic experiences are for individuals accessing health
and social services, and it provides information to help service
prov...iders recognize the adaptations people make to cope with
trauma. Trauma awareness is a foundation for developing
trauma-informed services, which integrate knowledge about
trauma into policies, procedures, and practices. Traumainformed
services actively seek to avoid re-traumatization and
have been shown to improve client engagement, retention, and
outcomes. This guide includes practice examples, suggested
resources, and sample questions to stimulate further discussion.

Cognitive deficits in schizophrenia can massively impact functionality and quality of life, furthering the importance of cognitive training. Despite the development of the field in Europe and in the United States, no programmes have been developed and tested in developing countries. Different cultur...al backgrounds, budget restrictions, and other difficulties may render treatment packages created in high income countries difficult for adoption by developing nations. We performed a pilot double-blind, randomized, controlled trial in order to investigate the efficacy and feasibility of an attention and memory training programme specially created in
a developing nation. The intervention used simple, widely available materials, required minimal infrastructure, and was conducted in groups.The sample included seventeen stable Brazilians with schizophrenia. Sessions were conducted weekly during five months. The cognitive training group showed significant improvements in inhibitory control and set-shifting over time. Both groups showed improvements in symptoms, processing speed, selective attention, executive function, and long-term visual memory. Improvements were found in the control group in long-term verbal memory and concentration. Our findings reinforce the idea that cognitive training in schizophrenia can be constructed using simple resources and infrastructure, facilitating its adoption by developing countries, and it may improve cognition.
