A randomized controlled trial of an early-intervention, computer-based literacy program to boost phonological skills in 4- to 6-year-old children

Background: Many school-based interventions are being delivered in the absence of evidence of effectiveness (Snowling & Hulme, 2011, Br. J. Educ. Psychol., 81, 1).Aim: This study sought to address this oversight by evaluating the effectiveness of the commonly used the Lexia Reading Core5 intervention, with 4- to 6-year-old pupils in Northern Ireland.Sample: A total of 126 primary school pupils in year 1 and year 2 were screened on the Phonological Assessment Battery 2nd Edition (PhAB-2). Children were recruited from the equivalent year groups to Reception and Year 1 in England and Wales, and Pre-kindergarten and Kindergarten in North America.
Methods: A total of 98 below-average pupils were randomized (T0) to either an 8-week block (inline image = 647.51 min, SD = 158.21) of daily access to Lexia Reading Core5 (n = 49) or a waiting-list control group (n = 49). Assessment of phonological skills was completed at post-intervention (T1) and at 2-month follow-up (T2) for the intervention group only.
Results: Analysis of covariance which controlled for baseline scores found that the Lexia Reading Core5 intervention group made significantly greater gains in blending, F(1, 95) = 6.50, p = .012, partial η2 = .064 (small effect size) and non-word reading, F(1, 95) = 7.20, p = .009, partial η2 = .070 (small effect size). Analysis of the 2-month follow-up of the intervention group found that all group treatment gains were maintained. However, improvements were not uniform among the intervention group with 35% failing to make progress despite access to support. Post-hoc analysis revealed that higher T0 phonological working memory scores predicted improvements made in phonological skills.
Conclusions: An early-intervention, computer-based literacy program can be effective in boosting the phonological skills of 4- to 6-year-olds, particularly if these literacy difficulties are not linked to phonological working memory deficits.

O Efeito da Terapia Cognitivo Comportamental na Anorexia Nervosa: uma meta-análise

Introdução: A Anorexia Nervosa (AN) é a perturbação do comportamento alimentar (PCA) com a maior taxa de mortalidade de todos os transtornos psiquiátricos. Carateriza-se pela recusa em manter um peso corporal normal mínimo, pela distorção da imagem corporal e por um obsessivo medo de ganhar peso. Os comportamentos patológicos a ela associados podem levar a uma semi-inanição que necessita de cuidados médicos pluridisciplinares, muitas vezes, em regime de internamento. Vários ensais clínicos avaliaram a eficácia da Terapia Cognitivo- Comportamental (TCC), indicando que ela favorece a remissão ou a diminuição da frequência de episódios de compulsão alimentar, dos comportamentos purgativos e da restrição alimentar. Objetivo: Combinar os resultados da melhor evidência científica de forma a avaliar a eficácia da TCC em comparação com outras terapias utilizadas no tratamento da AN. Métodos: A pesquisa realizou-se nas bases de dados eletrónicas da MEDLINE, Psyc-Info, Embase, CCTR e de forma manual, incluindo ensaios clínicos controlados randomizados que comparam a TCC com qualquer outro tipo de intervenção no tratamento da AN. Resultados: Foram incluídos 10 estudos que envolveram 957 pacientes: dos quais 571 (59,7%) foram submetidos a tratamento com Terapia cognitivo comportamental e 556 (49,3%) a outras terapias. Não se registaram diferenças significativas nos resultados obtidos em diversos outcomes, exceto nas subescalas Restrições (z=3,03; p=0,02), Preocupações alimentares (z=2,98; p=0,002) e Preocupações com a forma (z=1,71; p=0,09) do EDE e nos scores da escala GAF (z=1,87; p=0,06). Registaram-se diferenças estatisticamente significativas no número de episódios bulímicos (z=2,61; p=0,009), número de episódios de indução de vómito (z=2,11; p=0,03) e no número de episódios de uso indevido de laxantes (z=3,04; p=0,002). Conclusão: A utilização da Terapia Cognitivo-Comportamental no tratamento de doentes com AN parece melhorar bastante os sintomas da doença, revelando-se particularmente eficaz nos resultados obtidos na Eating Disorder Examination Scale. A sua utilização parece levar a uma melhoria no scores da GAF, evidenciando uma melhoria geral do estado de saúde dos pacientes (redução dos episódios de vómito, bulimia e uso de laxantes). / Página | viii ABSTRACT Background: Anorexia Nervosa is an eating disorder with the highest mortality rate of all psychiatric disorders. It is characterized by refusal to maintain a minimally normal body weight, the distortion of body image and obsessive fear of gaining weight. The pathological behaviors associated with it can lead to semi-starvation, requiring medical treatment and multidisciplinary inpatient care. Several clinical trials evaluated the efficacy of Cognitive Behavioral Therapy (CBT) in lead to remission or reduction of the frequency of bingue eating episodes, purgative behaviors and food restriction. Objective: Combining the results of the best scientific evidence to assess the efficacy of CBT in comparison with other therapies used in the treatment of AN. Methods: The research was carried out in electronic databases of MEDLINE, Psyc- Info, Embase, CCTR and manually, including randomized controlled trials that compared CBT with any other type of intervention in the treatment of AN. Results: Of which 571 (59.7%) were treated with cognitive behavioral therapy and 556 (49.3%) to other therapies: 10 studies involving 957 patients were included. No significant differences in the results obtained in different outcomes, except subscales Restrictions (z = 3.03, p = 0.02), Eating Concerns (z = 2.98, p = 0.002) and Shape Concerns (z = 1.71, p = 0.09) in the scores of EDE and the GAF scale (z = 1.87, p = 0.06). There were statistically significant differences in the number of bulimic episodes (z = 2.61, p = 0.009), number of episodes of induced vomiting (z = 2.11, p = 0.03) and the number of occurrences of use misuse of laxatives (z = 3.04, p = 0.002). Conclusion: The use of cognitive-behavioral therapy in the treatment of patients with AN seems to greatly improve the symptoms of the disease, revealing particularly effective results in the Eating Disorder Examination Scale. Its use seems to lead to an improvement in the GAF scores, showing a general improvement of the health status of patients (reduction of episodes of vomiting, bulimia and laxative use).

Le blocage androgénique intermittent versus continu dans le traitement du cancer de la prostate

L’administration du blocage androgénique de façon intermittente pourrait offrir plusieurs avantages dans le traitement du cancer de la prostate. Toutefois, ce mode d’administration demeure controversé. Nous avons donc effectué une revue systématique et méta-analyse d’essais cliniques randomisés afin de comparer l’efficacité et la tolérabilité du blocage androgénique intermittent versus continu. Une analyse de non-infériorité a été effectuée pour la survie avec un seuil préétabli de 1,15 pour la borne supérieure de l’intervalle de confiance (IC). Au total, 15 études étaient éligibles. Le blocage androgénique intermittent était non inférieur au blocage androgénique continu avec un hazard ratio de 1,02 (IC à 95%: 0,93-1,11). Il y avait peu de différence entre les deux groupes pour la qualité de vie globale. Toutefois, plusieurs études ont rapporté une meilleure fonction physique et sexuelle avec le traitement intermittent. Le blocage androgénique intermittent est une alternative thérapeutique acceptable dans le cancer de la prostate.

Amphetamine increases blood pressure and heart rate but has no effect on motor recovery or cerebral haemodynamics in ischaemic stroke: a randomized controlled trial (ISRCTN 36285333)

Amphetamine enhances recovery after experimental ischaemia and has shown promise in small clinical trials when combined with motor or sensory stimulation. Amphetamine, a sympathomimetic, might have haemodynamic effects in stroke patients, although limited data have been published. Subjects were recruited 3-30 days post ischaemic stroke into a phase II randomised (1:1), double blind, placebo-controlled trial. Subjects received dexamphetamine (5mg initially, then 10mg for 10 subsequent doses with 3 or 4 day separations) or placebo in addition to inpatient physiotherapy. Recovery was assessed by motor scales (Fugl-Meyer, FM), and functional scales (Barthel index, BI and modified Rankin score, mRS). Peripheral blood pressure (BP), central haemodynamics and middle cerebral artery blood flow velocity were assessed before, and 90 minutes after, the first 2 doses. 33 subjects were recruited, age 33-88 (mean 71) years, males 52%, 4-30 (median 15) days post stroke to inclusion. 16 patients were randomised to placebo and 17 amphetamine. Amphetamine did not improve motor function at 90 days; mean (standard deviation) FM 37.6 (27.6) vs. control 35.2 (27.8) (p=0.81). Functional outcome (BI, mRS) did not differ between treatment groups. Peripheral and central systolic BP, and heart rate, were 11.2 mmHg (p=0.03), 9.5 mmHg (p=0.04) and 7 beats/minute (p=0.02) higher respectively with amphetamine, compared with control. A non-significant reduction in myocardial perfusion (Buckberg Index) was seen with amphetamine. Other cardiac and cerebral haemodynamics were unaffected. Amphetamine did not improve motor impairment or function after ischaemic stroke but did significantly increase BP and heart rate without altering cerebral haemodynamics.

Musicoembriologia – qual o impacto no neurodesenvolvimento infantil

Introdução: A musicoembriologia engloba a audição de música durante a gravidez, com o objetivo de melhorar a relação materno-fetal e o neurodesenvolvimento infantil. Contudo, a relação entre estes ainda não está bem estabelecida, pelo que permanece um tema controverso. Objetivo: Rever a evidência disponível sobre o impacto da audição de música durante a gravidez no neurodesenvolvimento infantil. Material e Métodos: Pesquisa de meta-análises (MA), revisões sistemáticas (RS), ensaios clínicos aleatorizados e contro- lados (ECAC), e normas de orientação clinica (NOC), em inglês e português, publicados entre 01/2004 e 04/2014, nas bases de dados Pubmed/Medline, sítios de medicina baseada na evidência e Índex de Revistas Médicas Portuguesas, utilizando os termos MeSH: music; pregnancy; child; neurodevelopment. Para a avaliação dos níveis de evidência (NE) e atribuição de forças de recomendação (FR) foi utilizada a escala SORT (Strength of Recommendation Taxonomy) da American Family Phisician. Resultados: Foram encontrados onze artigos, dos quais quatro foram selecionados: três ECAC e uma RS. Um ECAC (NE 1) mostrou melhoria significativa do comportamento neonatal nas crianças cujas mães ouviram música durante a gravidez. Outro ECAC (NE 2) demonstrou uma melhoria da relação ma- terno-fetal com a musicoembriologia. Outro ECAC (NE3) e a RS (FR B) demonstraram que o ambiente intrauterino é importante no neurodesenvolvimento neonatal, sobretudo no desenvolvi- mento do córtex cerebral motor e neurosensorial. Conclusões: A evidência disponível demonstrou que a au- dição de música durante o período embrionário apresenta benefício no neurodesenvolvimento infantil. (FR B) No entanto os estudos obtidos são em número reduzido e apresentam grande heterogeneidade em termos metodológicos. São necessários mais estudos, com populações controladas e metodologia semelhantes, para a recomendação global desta medida.

Dipyridamole plus aspirin versus aspirin alone in the secondary prevention after TIA or stroke: a meta-analysis by risk

Objectives: Our aim was to study the effect of combination therapy with aspirin and dipyridamole (A+D) over aspirin alone (ASA) in secondary prevention after transient ischemic attack or minor stroke of presumed arterial origin and to perform subgroup analyses to identify patients that might benefit most from secondary prevention with A+D. Data sources: The previously published meta-analysis of individual patient data was updated with data from ESPRIT (N=2,739); trials without data on the comparison of A+D versus ASA were excluded. Review methods: A meta-analysis was performed using Cox regression, including several subgroup analyses and following baseline risk stratification. Results: A total of 7,612 patients (5 trials) were included in the analyses, 3,800 allocated to A+D and 3,812 to ASA alone. The trial-adjusted hazard ratio for the composite event of vascular death, non-fatal myocardial infarction and non-fatal stroke was 0.82 (95% confidence interval 0.72-0.92). Hazard ratios did not differ in subgroup analyses based on age, sex, qualifying event, hypertension, diabetes, previous stroke, ischemic heart disease, aspirin dose, type of vessel disease and dipyridamole formulation, nor across baseline risk strata as assessed with two different risk scores. A+D were also more effective than ASA alone in preventing recurrent stroke, HR 0.78 (95% CI 0.68 – 0.90). Conclusion: The combination of aspirin and dipyridamole is more effective than aspirin alone in patients with TIA or ischemic stroke of presumed arterial origin in the secondary prevention of stroke and other vascular events. This superiority was found in all subgroups and was independent of baseline risk. ---------------------------7dc3521430776 Content-Disposition: form-data; name="c14_creators_1_name_family" Halkes

Therapeutic efficacy of alternative primaquine regimens to standard treatment in preventing relapses by Plasmodium vivax : A systematic review and meta-analysis

Objective: To compare efficacy and safety of primaquine regimens currently used to prevent relapses by Plasmodium vivax. Methods: A systematic review was carried out to identify clinical trials evaluating efficacy and safety to prevent malaria recurrences by P. vivax of primaquine regimen 0.5 mg/kg/day for 7 or 14 days compared to standard regimen of 0.25 mg/kg/day for 14 days. Efficacy of primaquine according to cumulative incidence of recurrences after 28 days was determined. The overall relative risk with fixed-effects meta-analysis was estimated. Results: For the regimen 0.5 mg/kg/day/7 days were identified 7 studies, which showed an incidence of recurrence between 0% and 20% with follow-up 60-210 days; only 4 studies comparing with the standard regimen 0.25 mg/kg/day/14 days and no difference in recurrences between both regimens (RR= 0.977, 95% CI= 0.670 to 1.423) were found. 3 clinical trials using regimen 0.5 mg/kg/day/14 days with an incidence of recurrences between 1.8% and 18.0% during 330-365 days were identified; only one study comparing with the standard regimen (RR= 0.846, 95% CI= 0.484 to 1.477). High risk of bias and differences in handling of included studies were found. Conclusion: Available evidence is insufficient to determine whether currently PQ regimens used as alternative rather than standard treatment have better efficacy and safety in preventing relapse of P. vivax. Clinical trials are required to guide changes in treatment regimen of malaria vivax.

Oral chondroitin sulfate and prebiotics for the treatment of canine Inflammatory Bowel Disease: a randomized, controlled clinical trial

BACKGROUND Canine inflammatory bowel disease (IBD) is a chronic enteropathy of unknown etiology, although microbiome dysbiosis, genetic susceptibility, and dietary and/or environmental factors are hypothesized to be involved in its pathogenesis. Since some of the current therapies are associated with severe side effects, novel therapeutic modalities are needed. A new oral supplement for long-term management of canine IBD containing chondroitin sulfate (CS) and prebiotics (resistant starch, β-glucans and mannaoligosaccharides) was developed to target intestinal inflammation and oxidative stress, and restore normobiosis, without exhibiting any side effects. This double-blinded, randomized, placebo-controlled trial in dogs with IBD aims to evaluate the effects of 180 days administration of this supplement together with a hydrolyzed diet on clinical signs, intestinal histology, gut microbiota, and serum biomarkers of inflammation and oxidative stress. RESULTS Twenty-seven client-owned biopsy-confirmed IBD dogs were included in the study, switched to the same hydrolyzed diet and classified into one of two groups: supplement and placebo. Initially, there were no significant differences between groups (p > 0.05) for any of the studied parameters. Final data analysis (supplement: n = 9; placebo: n = 10) showed a significant decrease in canine IBD activity index (CIBDAI) score in both groups after treatment (p < 0.001). After treatment, a significant decrease (1.53-fold; p < 0.01) in histologic score was seen only in the supplement group. When groups were compared, the supplement group showed significantly higher serum cholesterol (p < 0.05) and paraoxonase-1 (PON1) levels after 60 days of treatment (p < 0.01), and the placebo group showed significantly reduced serum total antioxidant capacity (TAC) levels after 120 days (p < 0.05). No significant differences were found between groups at any time point for CIBDAI, WSAVA histologic score and fecal microbiota evaluated by PCR-restriction fragment length polymorphism (PCR-RFLP). No side effects were reported in any group. CONCLUSIONS The combined administration of the supplement with hydrolyzed diet over 180 days was safe and induced improvements in selected serum biomarkers, possibly suggesting a reduction in disease activity. This study was likely underpowered, therefore larger studies are warranted in order to demonstrate a supplemental effect to dietary treatment of this supplement on intestinal histology and CIBDAI.

Physical therapy for urinary incontinence in postmenopausal women with osteoporosis or low bone density : a randomized controlled trial

Objective: To assess the effectiveness of 12 weekly physical therapy sessions for urinary incontinence (UI) compared with a control intervention, for reducing the number of UI episodes measured with the 7-day bladder diary, at 3 months and 1 year postrandomization. Methods: A single parallel-group randomized controlled trial was conducted at one outpatient public health center, in postmenopausal women aged 55 years and over with osteoporosis or low bone density and UI. Women were randomized to physical therapy (PT) for UI or osteoporosis education. The primary outcome measure was number of leakage episodes on the 7-day bladder diary, assessed at baseline, after treatment and at 1 year. The secondary outcome measures included the pad test and disease-specific quality of life and self-efficacy questionnaires assessed at the same timepoints. Results: Forty-eight women participated (24 per group). Two participants dropped out of each group and one participant was deceased before 3-month follow-up. Intention-to-treat analysis was undertaken. At 3 months and 1 year, there was a statistically significant difference in the number of leakage episodes on the 7-day bladder diary (3 mo: P = 0.04; 1 y: P = 0.01) in favor of the PT group. The effect size was 0.34 at 1 year. There were no harms reported. Conclusions: After a 12-week course of PT once per week for UI, PT group participants had a 75% reduction in weekly median number of leakage episodes, whereas the control group's condition had no improvement. At 1 year, the PT group participants maintained this improvement, whereas the control group's incontinence worsened.

Effectiveness of non-pharmacological interventions to prevent falls in older people: a systematic overview. The SENATOR Project ONTOP Series

Background: Falls are common events in older people, which cause considerable morbidity and mortality. Non-pharmacological interventions are an important approach to prevent falls. There are a large number of systematic reviews of non-pharmacological interventions, whose evidence needs to be synthesized in order to facilitate evidence-based clinical decision making. Objectives: To systematically examine reviews and meta-analyses that evaluated non-pharmacological interventions to prevent falls in older adults in the community, care facilities and hospitals. Methods: We searched the electronic databases Pubmed, the Cochrane Database of Systematic Reviews, EMBASE, CINAHL, PsycINFO, PEDRO and TRIP from January 2009 to March 2015, for systematic reviews that included at least one comparative study, evaluating any non-pharmacological intervention, to prevent falls amongst older adults. The quality of the reviews was assessed using AMSTAR and ProFaNE taxonomy was used to organize the interventions. Results: Fifty-nine systematic reviews were identified which consisted of single, multiple and multi-factorial non-pharmacological interventions to prevent falls in older people. The most frequent ProFaNE defined interventions were exercises either alone or combined with other interventions, followed by environment/assistive technology interventions comprising environmental modifications, assistive and protective aids, staff education and vision assessment/correction. Knowledge was the third principle class of interventions as patient education. Exercise and multifactorial interventions were the most effective treatments to reduce falls in older adults, although not all types of exercise were equally effective in all subjects and in all settings. Effective exercise programs combined balance and strength training. Reviews with a higher AMSTAR score were more likely to contain more primary studies, to be updated and to perform meta-analysis. Conclusions: The aim of this overview of reviews of non-pharmacological interventions to prevent falls in older people in different settings, is to support clinicians and other healthcare workers with clinical decision-making by providing a comprehensive perspective of findings.

L’utilisation libérale des transfusions de plaquettes dans la réanimation initiale des patients polytraumatisés

Cette revue systématique évalue l’effet d’une utilisation libérale de plaquettes (ratio élevé plaquettes:culots globulaires) en comparaison à une utilisation traditionnelle (faible ratio plaquettes:culots globulaires) dans la réanimation initiale des polytraumatisés. Parmi 6123 références identifiées, nous avons sélectionné 7 études observationnelles comparatives incluant au total 4230 patients. Quatre études ont rapporté une diminution de la mortalité avec des ratios plaquettes:culots globulaires élevés chez des patients transfusés massivement. Une étude sur des patients sans hémorragie massive et une étude sur un nouveau protocole de transfusion massive n’ont rapporté aucune différence. L’hétérogénéité clinique et les failles méthodologiques des études n’ont pas permis d’effectuer une méta-analyse. Les données probantes actuelles sont insuffisantes pour appuyer l’utilisation d’un ratio plaquettes:culots globulaires spécifique dans la réanimation des polytraumatisés, surtout en considérant le biais de survie et les hémorragies non massives. Des essais cliniques randomisés évaluant la sécurité et l’efficacité d’un ratio élevé plaquettes:culots globulaires sont nécessaires avant de recommander leur utilisation.
