A mixed-methods study of applied team integration for opioid use disorder treatment in rural settings
The Opioid epidemic and the subsequent Opioid use disorders (OUD) stemming from this epidemic have devastated individuals, families, and communities. These impacts have an outsized effect on rural communities and are exacerbated by the discrepancy in best practice recommendations that call for a resource-intensive framework of integrated treatment options and the limited treatment resources found in rural communities. This pilot study explores da…
Family lifestyle dynamics and childhood obesity
The analysis suggests that interventions should therefore be prolonged and persuasive and target the underlying lifestyle of a family as early as possible during childhood in order to have the greatest cumulative influence. Our results suggest that children from advantaged backgrounds are more likely to be exposed to healthier lifestyles and that this leads to inequalities in the prevalence of obesity. To reduce inequalities in childhood obesity,…
Severe acute malnutrition in children aged under 5 years can be successfully managed in a non‐emergency routine community healthcare setting in Ghana
This study investigated the performance of community-based management of severe acute malnutrition (CMAM) within routine healthcare services in Ghana. This was a retrospective cohort study of n = 488 children (6-59 months) who had received CMAM. Data for recovery, default, and mortality rates were obtained from enrolment cards in 56 outpatient centres in Upper East region, Ghana. Satisfactory rates of recovery of 71.8% were reported. Children who…
Consort 2010 statement
The Consolidated Standards of Reporting Trials (CONSORT) statement is a guideline designed to improve the transparency and quality of the reporting of randomised controlled trials (RCTs). In this article we present an extension to that statement for randomised pilot and feasibility trials conducted in advance of a future definitive RCT. The checklist applies to any randomised study in which a future definitive RCT, or part of it, is conducted on …
Estimating the sample size for a pilot randomised trial to minimise the overall trial sample size for the external pilot and main trial for a continuous outcome variable
Sample size justification is an important consideration when planning a clinical trial, not only for the main trial but also for any preliminary pilot trial. When the outcome is a continuous variable, the sample size calculation requires an accurate estimate of the standard deviation of the outcome measure. A pilot trial can be used to get an estimate of the standard deviation, which could then be used to anticipate what may be observed in the ma…
Black Resonance
Drawing on the critical binary between textuality and orality in African American literary study and the subsequent erosion of that binary, another complex interplay has assumed signal importance in the field over the past twenty years: that between music and text. This dynamic has produced a varied critical discourse that has constructed an interface between various forms of black music (jazz, blues, gospel, and hip-hop) and black poetry and pro…
Telecare lifestyle monitoring—built on a strong foundation
Older people may prefer to stay at home when health declines This experimental technology is based on the assumption that daily activities can be monitored to provide an indication of the health state of older people
The Design and Validation of a Parent-Report Questionnaire for Assessing the Characteristics and Quality of Early Intervention Over Time
This article concerns a parent-report repeat questionnaire to evaluate the quality of multiprofessional early intervention following early identification of deafness. It discusses the rationale for the design of the instrument, its theoretical underpinnings, its psychometric properties, and its usability. Results for the validity and reliability of the instrument are based on completion by 82 parents. The questionnaire is divided into four sectio…

The Sequence of the Human Genome
A 2.91-billion base pair (bp) consensus sequence of the euchromatic portion of the human genome was generated by the whole-genome shotgun sequencing method. The 14.8-billion bp DNA sequence was generated over 9 months from 27,271,853 high-quality sequence reads (5.11-fold coverage of the genome) from both ends of plasmid clones made from the DNA of five individuals. Two assembly strategies—a whole-genome assembly and a regional chromosome assembl…

Modelling influenza epidemics in the relation between black smoke and total mortality. A sensitivity analysis
3have been studied, but not diVerent methods for modelling influenza epidemics. In previous work influenza epidemics were controlled for by means of only one dummy variable, “1” denoting the occurrence of an epidemic and “0” otherwise. 13 Using this approach we cannot control for the possible variability in total daily mortality within influenza epidemic periods between years. Other authors have suggested using quantitative information about infl…
Clinical significance not statistical significance
OBJECTIVES: To take the common "Bayesian" interpretation of conventional confidence intervals to its logical conclusion, and hence to derive a simple, intuitive way to interpret the results of public health and clinical studies. DESIGN AND SETTING: The theoretical basis and practicalities of the approach advocated is at first explained and then its use is illustrated by referring to the interpretation of a real historical cohort study. The study …

Is there an increased risk of twinning after discontinuation of the oral contraceptive pill
We investigated whether conception soon after cessation of use of oral contraceptives affects the chance of bearing twins. Unpublished data from a large sample survey of contraceptive practice in Scotland were used to derive oral contraceptive discontinuation rates by month over the decade 1972-82 and these were related to estimated monozygotic and dizygotic twin birth rates and proportions by month in Scotland from 1974-82, using regression tech…
Twenty years' screening for cancer of the uterine cervix in Great Britain, 1964-84
The effects of the screening programme for cancer of the uterine cervix in Great Britain are disputed, and the subject has been underexplored. Accordingly, we have related routinely available data on screening effort in Scotland, Wales, and the 14 English Health Regions to various incidence and mortality outcome measures, from 1967 to the present day. Although such an approach is imperfect, the results support the belief that the screening progra…
Sudden infant death syndrome and environmental temperature
We examined the relation between the daily numbers of deaths ascribed to sudden infant death syndrome (SIDS) (n = 6226) and daily temperature in England and Wales over the five year period 1979-83. When the data were filtered to remove the dominant seasonal trend, and residual autocorrelation, we found a significant negative correlation of deaths with both the level and rate of change of temperature four to six days earlier, irrespective of age a…
