Differences in parental attitudes and tolerance of child exposure to and participation in gambling, alcohol and nicotine use

This study investigated parental attitudes toward child exposure to alcohol, nicotine (smoking tobacco) and gambling, via a questionnaire that examined parental tolerance with regard to hypothetical scenarios of exposure and participation, alongside perceptions of the importance of associated health promotion for each activity. It was hypothesised that parents would indicate significantly less tolerance of, and rate health promotion activity of greater importance for, nicotine and alcohol in comparison to gambling. Results from a sample of 500 UK based parents, showed significantly less tolerance for nicotine versus alcohol and gambling in all hypothetical scenarios of exposure and direct participation. Parents also reported significantly less tolerance surrounding child consumption of alcohol than gambling. Health promotion activity surrounding nicotine was rated significantly more important than that of alcohol and gambling. It is argued that greater parental concern surrounding nicotine was attributable to increased availability of knowledge surrounding associated risks of smoking behaviour within existing regulation and health promotion activity. Arguments are made for increased public awareness of the potential harms that may be associated with gambling behaviour, which may assist parents in making informed decisions regarding their children’s exposure to and participation in gambling-related activities

Systematic review and stratified meta-analysis of the efficacy of RhoA and Rho kinase inhibitors in animal models of ischaemic stroke

There is currently only one clinically approved drug, tissue plasminogen activator (tPA), for the treatment of acute ischaemic stroke. The RhoA pathway, including RhoA and its downstream effector Rho kinase (ROCK), has been identified as a possible therapeutic target. Our aim was to assess the impact of study design characteristics and study quality on reported measures of efficacy and to assess for the presence and impact of publication bias. We conducted a systematic review and meta-analysis on publications describing the efficacy of RhoA and ROCK inhibitors in animal models of focal cerebral ischaemia where outcome was assessed as a change in lesion size or neurobehavioural score, or both. We identified 25 published papers which met our inclusion criteria. RhoA and ROCK inhibitors reduced lesion size by 37.3% in models of focal cerebral ischaemia (95% CI, 28.6% to 46.0%, 41 comparisons), and reduced neurobehavioural data by 40.5% (33.4% to 47.7%, 30 comparisons). Overall study quality was low (median=4, interquartile range 3-5) and measures to reduce bias were seldom reported. Publication bias was prevalent and associated with a substantial overstatement of efficacy for lesion size. RhoA and ROCK inhibitors appear to be effective in animal models of stroke. However the low quality score, publication bias and limited number of studies are areas which need attention prior to conducting clinical trials

A meta-analytic review of stand-alone interventions to improve body image

Objective Numerous stand-alone interventions to improve body image have been developed. The present review used meta-analysis to estimate the effectiveness of such interventions, and to identify the specific change techniques that lead to improvement in body image. Methods The inclusion criteria were that (a) the intervention was stand-alone (i.e., solely focused on improving body image), (b) a control group was used, (c) participants were randomly assigned to conditions, and (d) at least one pretest and one posttest measure of body image was taken. Effect sizes were meta-analysed and moderator analyses were conducted. A taxonomy of 48 change techniques used in interventions targeted at body image was developed; all interventions were coded using this taxonomy. Results The literature search identified 62 tests of interventions (N = 3,846). Interventions produced a small-to-medium improvement in body image (d+ = 0.38), a small-to-medium reduction in beauty ideal internalisation (d+ = -0.37), and a large reduction in social comparison tendencies (d+ = -0.72). However, the effect size for body image was inflated by bias both within and across studies, and was reliable but of small magnitude once corrections for bias were applied. Effect sizes for the other outcomes were no longer reliable once corrections for bias were applied. Several features of the sample, intervention, and methodology moderated intervention effects. Twelve change techniques were associated with improvements in body image, and three techniques were contra-indicated. Conclusions The findings show that interventions engender only small improvements in body image, and underline the need for large-scale, high-quality trials in this area. The review identifies effective techniques that could be deployed in future interventions

What is psychiatry? Co-producing complexity in mental health

What is psychiatry? Such a question is increasingly important to engage with in light of the development of new diagnostic frameworks that have wide-ranging and international clinical and societal implications. I suggest in this reflective essay that ‘psychiatry' is not a singular entity that enjoins consistent forms of critique along familiar axes; rather, it is a heterogeneous assemblage of interacting material and symbolic elements (some of which endure, and some of which are subject to innovation). In underscoring the diversity of psychiatry, I seek to move towards further sociological purchase on what remains a contested and influential set of discourses and practices. This approach foregrounds the relationships between scientific knowledge, biomedical institutions, social action and subjective experience; these articulations co-produce both psychiatry and each other. One corollary of this emphasis on multiplicity and incoherence within psychiatric theory, research and practice, is that critiques which elide this complexity are rendered problematic. Engagements with psychiatry are, I argue, best furthered by recognising its multifaceted nature

Ar dreno pašalinimo laikas turi įtakos pirminio spontaninio pneumotorakso pirmojo epizodo gydymo išeitims?

Background / objectives. The main treatment option for the first episode of primary spontaneous pneumothorax is chest tube drainage, however, whether delayed chest tube removal might influence the recurrence is unclear.Methods. A prospective study, which included 50 patients, with an initial episode of primary spontaneous pneumothorax was performed. Patients were randomized into two groups according to the chest tube removal time: 1-day and 5-days after the air-leak has stopped. All patients were followed-up for at least six months. Both groups were compared according to the recurrence rate and possible complications.Results. There were 39 (78%) men and the median age was 27 (23–35) years. Successful management with a chest tube was achieved in 43 (86%) patients, others were operated on because of the continuous air-leak or relapse of the pneumothorax after the chest tube was removed. Significant difference was not found comparing groups by age, gender, side, tobacco smoking, alpha-1-antitrypsin level, rate of prolonged air-leak, necessity of surgery, and the mean follow-up time. There was a significant difference between groups in hospitalization time: 1-day group – 6 (4–12), 5-days group – 8 (7–10) days, p = 0.017. Five (20%) patients from 1-day group and 3 (12%) from 5-days group had a recurrence, however the difference was not significant (p = 0.702). There were no significant differences comparing groups by the recurrence time or complications.Conclusions. The recurrence rate of primary spontaneous pneumothorax was higher if the chest tube was removed earlier, however not significantly. More data and longer follow-up are necessary to confirm these findings.Įvadas / tikslas. Pirminis spontaninis pneumotoraksas yra didelė jaunų sveikų žmonių problema. Pleuros ertmės drenavimas – pagrindinis pirminio spontaninio pneumotorakso pirmojo epizodo gydymo būdas. Vis dėlto nėra žinoma, ar dreno buvimo pleuros ertmėje trukmė gali turėti įtakos recidyvų dažniui.Metodai. Atliktas perspektyvusis tyrimas, į kurį įtraukta 50 pacientų. Tiriamiesiems diagnozuotas pirminio spontaninio pneumotorakso pirmasis epizodas. Visi pacientai gydyti drenuojant pleuros ertmę. Pacientai suskirstyti į dvi grupes, atsižvelgiant į dreno pašalinimo laiką: praėjus vienai dienai ar praėjus penkioms dienoms, kai per dreną nustojo skirtis oras. Visi pacientai atokiu laikotarpiu (mažiausiai šešis mėnesius) stebėti dėl galimo recidyvo. Atlikta abiejų grupių recidyvų dažnio ir galimų komplikacijų lyginamoji analizė.Rezultatai. Vidutinis pacientų amžius – 27 (23–35) metai. 78 proc. tiriamųjų – vyrai. Drenavus pleuros ertmę, sėkmingai išgydyti 43 ligoniai (86 %). Kiti tiriamieji dėl besiskiriančio per dreną oro ar dėl rentgenogramoje matomo pakartotinio pneumotorakso, pašalinus dreną, buvo operuoti. Abiejų tiriamųjų grupių duomenys pagal amžių, lytį, pneumotorakso pasireiškimo krūtinės ląstoje pusę, rūkymą, alfa-1 antitripsino koncentraciją kraujyje, ilgesnį oro skyrimąsi per dreną ar operacijos poreikį statistiškai reikšmingai nesiskyrė. Statistiškai reikšmingai skyrėsi abiejų grupių hospitalizacijos trukmė: tiriamieji, kuriems, nustojus per dreną skirtis orui, drenas pašalintas praėjus vienai dienai, ligoninėje gulėjo vidutiniškai 6 (4–12) dienas, o tiriamieji, kuriems drenas pašalintas praėjus penkioms dienoms, – 8 (7–10) dienas (p = 0,017). Penkiems (20 %) pirmosios grupės ir trims (12 %) antrosios grupės pacientams pneumotoraksas recidyvavo (skirtumas statistiškai nereikšmingas (p = 0,702)). Statistiškai nereikšmingas skirtumas nustatytas ir tarp abiejų grupių recidyvo laiko bei komplikacijų.Išvados. Pirminio spontaninio pneumotorakso recidyvų dažnis kiek didesnis, kai drenas ištraukiamas anksčiau, tačiau lyginamųjų grupių skirtumas statistiškai nereikšmingas. Siekiant patvirtinti gautus rezultatus, reikia atlikti didesnės apimties tyrimą, būtina ilgiau stebėti tiriamuosius

Publication bias in situ

BACKGROUND: Publication bias, as typically defined, refers to the decreased likelihood of studies' results being published when they are near the null, not statistically significant, or otherwise "less interesting." But choices about how to analyze the data and which results to report create a publication bias within the published results, a bias I label "publication bias in situ" (PBIS). DISCUSSION: PBIS may create much greater bias in the literature than traditionally defined publication bias (the failure to publish any result from a study). The causes of PBIS are well known, consisting of various decisions about reporting that are influenced by the data. But its impact is not generally appreciated, and very little attention is devoted to it. What attention there is consists largely of rules for statistical analysis that are impractical and do not actually reduce the bias in reported estimates. PBIS cannot be reduced by statistical tools because it is not fundamentally a problem of statistics, but rather of non-statistical choices and plain language interpretations. PBIS should be recognized as a phenomenon worthy of study – it is extremely common and probably has a huge impact on results reported in the literature – and there should be greater systematic efforts to identify and reduce it. The paper presents examples, including results of a recent HIV vaccine trial, that show how easily PBIS can have a large impact on reported results, as well as how there can be no simple answer to it. SUMMARY: PBIS is a major problem, worthy of substantially more attention than it receives. There are ways to reduce the bias, but they are very seldom employed because they are largely unrecognized

Encouraging female entrepreneurship in Jordan: environmental factors, obstacles and challenges

The number of female entrepreneurs and their contribution to the economy is steadily rising. Yet research suggests that female entrepreneurs face more challenges and barriers than their male counterparts. This is expected to be even more prevalent in Islamic contexts, which are characterised by conservative and patriarchal societies. In this research, 254 female business students from a private and a public university responded to a questionnaire that gauges their perceptions about potential barriers to entrepreneurship in Jordan and whether the business education they are receiving helps to prepare them for future entrepreneurial activity. Our results help to form a basis on which a deeper understanding of the phenomena can be achieved through more in depth future research. Among the main environmental factors that worry potential female entrepreneurs are the weakness of Jordanian economy, lack of finance, fear of risk, gender inequality and inability to maintain a work and private life balance. Our results also show that students are really not aware of the opportunities available to them and are unable to make a proper assessment. We call on both universities and the Jordanian government to put more emphasis on practical entrepreneurial education and encouraging women to play a much more active role within the workforce

School Effects on the Wellbeing of Children and Adolescents

Well-being is a multidimensional construct, with psychological, physical and social components. As theoretical basis to help understand this concept and how it relates to school, we propose the Self-Determination Theory, which contends that self-determined motivation and personality integration, growth and well-being are dependent on a healthy balance of three innate psychological needs of autonomy, relatedness and competence. Thus, current indicators involve school effects on children’s well-being, in many diverse modalities which have been explored. Some are described in this chapter, mainly: the importance of peer relationships; the benefits of friendship; the effects of schools in conjunction with some forms of family influence; the school climate in terms of safety and physical ecology; the relevance of the teacher input; the school goal structure and the implementation of cooperative learning. All these parameters have an influence in promoting optimal functioning among children and increasing their well-being by meeting the above mentioned needs. The empirical support for the importance of schools indicates significant small effects, which often translate into important real-life effects as it is admitted at present. The conclusion is that schools do make a difference in children’s peer relationships and well-being

Investigating and dealing with publication bias and other reporting biases in meta-analyses:a review

A P value, or the magnitude or direction of results can influence decisions about whether, when, and how research findings are disseminated. Regardless of whether an entire study or a particular study result is unavailable because investigators considered the results to be unfavourable, bias in a meta-analysis may occur when available results differ systematically from missing results. In this paper, we summarize the empirical evidence for various reporting biases that lead to study results being unavailable for inclusion in systematic reviews, with a focus on health research. These biases include publication bias and selective nonreporting bias. We describe processes that systematic reviewers can use to minimize the risk of bias due to missing results in meta-analyses of health research, such as comprehensive searches and prospective approaches to meta-analysis. We also outline methods that have been designed for assessing risk of bias due to missing results in meta-analyses of health research, including using tools to assess selective nonreporting of results, ascertaining qualitative signals that suggest not all studies were identified, and generating funnel plots to identify small-study effects, one cause of which is reporting bias.
