Effect of Bright Light Therapy on Perinatal Depression: A Systematic Review and Meta-Analysis: Effet de la luminothérapie sur la dépression périnatale: une revue systématique et une méta-analyse.

OBJECTIVE: This study represents the inaugural attempt to systematically review and analyse the efficacy of bright light therapy on depression among women experiencing major depressive disorder or depressive symptoms during the perinatal period, encompassing its efficacy on depression scores, remission rates, and response rates. METHODS: We searched 10 databases for randomized controlled trials examining bright light therapy's efficacy on perinatal depression up to January 2024. Data extraction was performed independently by 2 investigators. The Cochrane Handbook guidelines appraised the study quality, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach assessed evidence certainty. RESULTS: We incorporated 6 studies, encompassing 151 participants. When contrasted with dim light therapy, bright light therapy did not significantly alter depression scores (standard mean difference = -0.29, 95% confidence interval [CI], -0.62 to 0.04, P = 0.08, I² = 34%) or response rates (risk ratio [RR] = 1.56, 95% CI, 0.98 to 2.49, P = 0.06, I² = 0%) in women experiencing perinatal depression. Conversely, bright light therapy was associated with a substantial increase in remission rates (RR = 2.63, 95% CI, 1.29 to 5.38, P = 0.008, I² = 2%). CONCLUSION: Bright light therapy did not show efficacy in treating perinatal depression in terms of depression scores and response rates. However, regarding the remission rate, bright light did show efficacy compared to control conditions. Due to the limited sample size in the included studies, type II err or may occur. To obtain more conclusive evidence, future studies must employ larger sample sizes.

Prevalence rate of ADHD in France: Review of the literature and results from ChiP-ARD study.

OBJECTIVES: Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder whose first clinical description was published more than two centuries ago. Prevalence rates have been evaluated in many countries and meta-analyses conducted, but the data collected in France are scarce. METHODS: A review of the literature was conducted by retrieving the references from four electronic databases leading to the selection of four studies in children and four in adults. Meta-analyses of prevalence rates were performed on this published data as well as unpublished results from the ChiP-ARD study (Children and Parents with ADHD and Related Disorders), separately for children and adults. RESULTS: While the quality of most studies is questionable, the prevalence rates are close to those reported in international meta-analytic studies for children (3.68%), but are higher in adults (5.5%). CONCLUSIONS: Well-conducted studies in both general and special populations are needed (e.g., in patients with depression, anxiety, bipolar disorder, developmental disorders including autism spectrum disorder, behavioural or substance abuse, and incarcerated). Nevertheless, healthcare stakeholders can conservatively consider that .8 million children and 1.4 million adults in the metropolitan French general population are likely to have ADHD and suffer from its multiple consequences.

Functional analysis of co-expression networks of zebrafish ace2 reveals enrichment of pathways associated with development and disease.

Human Angiotensin I Converting Enzyme 2 (ACE2) plays an essential role in blood pressure regulation and SARS-CoV-2 entry. ACE2 has a highly conserved, one-to-one ortholog (ace2) in zebrafish, which is an important model for human diseases. However, the zebrafish ace2 expression profile has not yet been studied during early development, between genders, across different genotypes, or in disease. Moreover, a network-based meta-analysis for the extraction of functionally enriched pathways associated with differential ace2 expression is lacking in the literature. Herein, we first identified significant development-, tissue-, genotype-, and gender-specific modulations in ace2 expression via meta-analysis of zebrafish Affymetrix transcriptomics datasets (ndatasets = 107); and the correlation analysis of ace2 meta-differential expression profile revealed distinct positively and negatively correlated local functionally enriched gene networks. Moreover, we demonstrated that ace2 expression was significantly modulated under different physiological and pathological conditions related to development, tissue, gender, diet, infection, and inflammation using additional RNA-seq datasets. Our findings implicate a novel translational role for zebrafish ace2 in organ differentiation and pathologies observed in the intestines and liver.

Enhancing parental reflective functioning through early dyadic interventions: A systematic review and meta-analysis.

Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent-infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part of their theory of change, and some that do not explicitly target PRF, but that have measured it as an outcome. However, no meta-analytic review of the impact of these interventions has been carried out to date. The aim of this review was to evaluate the effectiveness of dyadic interventions targeting parents of infant and toddlers, in improving PRF and a number of secondary outcomes. A systematic review and meta-analysis was conducted in which key electronic databases were searched up to October 2018. Eligible studies were identified and data extracted. Data were synthesised using meta-analysis and expressed as both effect sizes and risk ratios. Six studies were identified providing a total of 521 participants. The results of six meta-analyses showed a nonsignificant moderate improvement in PRF in the intervention group (standardised mean difference [SMD]: -0.46; 95% confidence interval [CI] [-0.97, 0.04]) and a significant reduction in disorganised attachment (risk ratio: 0.50; 95% CI [0.27, 0.90]). There was no evidence for intervention effects on attachment security (odds ratio: 0.71; 95% CI [0.19, 2.64]), parent-infant interaction (SMD: -0.10; 95% CI [-0.46, 0.26]), parental depression (SMD: -1.55; 95% CI [-3.74, 0.64]) or parental global distress (SMD: -0.19, 95% CI [-3.04, 22.65]). There were insufficient data to conduct subgroup analysis (i.e. to compare the effectiveness of mentalisation-based treatment with non-mentalization-based treatment interventions). Relational early interventions may have important benefits in improving PRF and reducing the prevalence of attachment disorganisation. The implications for future research are discussed.

El funcionamiento de reflexión del progenitor (PRF) es un factor importante de predicción de la afectividad del infante, y las intervenciones que se enfocan en díadas progenitor/infante/niño pequeñito que experimentan problemas significativos tienen la posibilidad de mejorar el PRF. La meta de esta revisión fue evaluar la eficacia de las intervenciones diádicas que se enfocan en los progenitores de infantes y niños pequeñitos, para mejorar el PRF y un número de resultados secundarios. Se llevó a cabo una revisión sistemática y un meta-análisis en los que se investigaron bancos de información electrónica claves hasta octubre de 2018. Se identificaron estudios elegibles y se sacó de ellos la información. Se sintetizó esa información usando meta-análisis y la misma fue presentada tanto en términos de dimensión de efectos como la proporción de riesgo. Se identificaron seis estudios que aportaron un total de 521 participantes. Los resultados de seis meta-análisis mostraron un moderado, poco significativo y limítrofe mejoramiento en cuanto al PRF en el grupo de intervención (SMD: -0.46; 95% CI -0.97, 0.04), una reducción significativa en la afectividad desorganizada (RR: 0.50; 95% CI: 0.27, 0.90), pero no así en la afectividad segura (OR: 0.71; 95% CI: 0.19, 2.64), y ninguna evidencia de beneficio para la interacción progenitor-infante (SMD: -0.09; 95% CI: -0.51, 0.32). Se dio un mejoramiento grande no significativo en la depresión del progenitor (SMD: -1.55; 95% CI -3.74, 0.64), pero no hubo evidencia de beneficio en cuanto a la angustia total (SMD: -0.19; 95% CI: -3.04, 22.65). Se discuten las implicaciones para la futura investigación.

Le fonctionnement parental réfléchi (en anglais Parental Reflective Functioning, soit PRF) est un facteur de prédiction important de l'attachement du bébé, et les interventions qui ciblent les dyades parent-bébé/petit enfant qui font l'expérience de problèmes importants ont le potentiel d'améliorer le fonctionnement PRF. Le but de cette article était d'évaluer l'efficacité d'interventions dyadiques ciblant les parents de bébés et de petits enfants, en améliorant le fonctionnement PRF et un bon nombre de résultats secondaires. Une revue et une méta-analyse ont été faites, les bases de données électroniques clés ayant été passées au crible en octobre 2018. Les études pouvant être utilisées ont été identifiées et les données ont été extraites. Les données ont été synthétisées en utilisant une méta-analyse et exprimées sous forme d'ampleur de l'effet et de risque relatif. Six études ont été identifiées, pour un total de 521 participants. Les résultats de six méta-analyses ont montré une amélioration limite non importante modérée dans le PRF dans le groupe d'intervention (SMD: -0,46; 95% CI -0,97, 0,04), une réduction importante dans l'attachement désorganisé de l'enfant (RR: 0,50; 95% CI: 0,27, 0,90) mais non dans l'attachement sécure (OR: 0,71; 95% CI: 0,19, 2,64), ainsi qu'aucune preuve de bénéfice pour l'interaction parent-bébé (SMD: -0,09; 95% CI -0,51, 0,32). Il y avait une grande amélioration non-importante dans la dépression parentale (SMD: -1,55; 95% CI -3,74, 0,64) mais aucune preuve de bénéfice dans la détresse globale (SMD: -0,19; 95% CI: -3,04, 22,65. Les implications pour les recherches futures sont discutées.

[Efficacy of psychodynamic therapies: A systematic review of the recent literature]. / L'efficacité des psychothérapies inspirées par la psychanalyse : une revue systématique de la littérature scientifique récente.

AIM: A French governmental institute published, in February 2004, a report assessing the efficacy of psychotherapies in the light of the biomedical literature. It concluded that cognitive psychotherapies effectively cure common mental disorders, while the efficacy of psychodynamic therapies is not proven by scientific studies. Because many French mental health professionals are practicing with reference to psychoanalysis, this conclusion stirred up heated controversy. Since February 2004, numerous studies assessing psychodynamic therapies have been published in peer-reviewed biomedical journals. Moreover, these primary studies have been meta-analyzed in dozens of review articles. Here, we systematically review these meta-analysis articles. METHODS: A systematic search for meta-analyses assessing psychodynamic therapies was performed using PubMed and identified 71 articles published from January 2004 to December 2019. Among them, 25 articles were judged to be relevant because they reported meta-analyses assessing the symptoms of common mental disorders in at least three distinct cohorts of adult patients. Although the primary studies included in these 25 meta-analysis articles often overlap, the selection criteria, calculation methods and results always differ between them. Therefore, we reviewed all of them without further selection. From all the meta-analyses reported in these 25 articles, we systematically present here the most compelling ones, i.e. those calculated from the largest number of primary studies. Results were quantified in terms of effect size (i.e. standardized mean difference). Effect sizes below 0.25 were considered as without clinical significance, whereas those superior to 0.8 were regarded as robust. Because short-term psychodynamic therapies had been assessed in 20 meta-analysis articles published until 2017, we did not search for more recent primary studies. However, because the most recent meta-analysis article about long-term psychodynamic therapies was published in 2013, we also searched, using PubMed, for primary studies assessing psychodynamic therapies lasting for at least one year and published from January 2013 to December 2019. Among the 57 publications retrieved by PubMed, three were identified as randomized controlled trials not included in meta-analyses and were extensively described here. RESULTS: Eight meta-analysis articles have assessed symptom improvement at treatment termination by comparing with baseline symptoms. According to all of them, psychodynamic therapies alleviate symptoms and their effect sizes are always robust. Three meta-analysis articles compared psychodynamic therapies with inactive treatments (e.g. placebo medication, waiting list) and reported clinically significant differences in favor of psychodynamic therapies. Ten meta-analysis articles compared, at treatment termination, psychodynamic therapies to active treatments, including medication and cognitive psychotherapies. Nine of them reported no difference. Only one article concluded that psychodynamic therapies are clinically inferior to cognitive psychotherapies (d=-0.28). Seven meta-analysis articles compared psychodynamic therapies to active treatment at follow-up (i.e. months or years after treatment termination). Five of them reported no significant difference, one reported a medium effect size in favor of psychodynamic therapies over various active treatments (d=0.38), while the other reported a clinically significant difference in favor of cognitive psychotherapies (d=-0.55). Because short-term treatments are often insufficient to prevent relapse, investigations about long-term treatments (i.e. more than one year) are needed, but such published studies are still scarce. Five meta-analysis articles and three primary studies published since 2013 compared long-term psychodynamic therapies to various active treatments of similar duration. According to them, psychodynamic therapies were at least as effective as other active treatments. CONCLUSION: A systematic review about psychodynamic therapies, published in 2015 in Lancet Psychiatry, included 64 randomized controlled trials of which 37 were published after 2003. Therefore, most quality studies assessing psychodynamic therapies have been published since 2003 and have been reviewed in recent meta-analysis articles. All together, this recent literature leads to the conclusion that psychodynamic therapies are as effective as active treatments, including cognitive psychotherapies, to help patients suffering from common mental disorders (unipolar depression, anxiety disorders, eating disorders and personality disorders). Beside this overall conclusion, it appears that randomized controlled trials are not well suited for answering why psychotherapies work in some patients but not in others, and how they work in general. Other approaches are needed, including case studies.

Adverse events associated with mirabegron 50mg versus placebo: A systematic review and meta-analysis.

PURPOSE: The safety of mirabegron 50mg monotherapy was comprehensively assessed versus placebo for overactive bladder. METHODS: A systematic literature search was conducted up to June, 2020 using PUBMED, EMBASE and Cochrane Library. Randomized controlled trials evaluating safety of mirabegron in overactive bladder were collected, and safety was assessed according to 15 adverse events. Adverse events were widely selected to be assessed if they could be calculated. Heterogeneity among studies was assessed by using the χ2 test based on the Q and I2 tests. Pooled effect sizes were calculated using fixed model if I2<50%, otherwise a random-effects model was chosen. The outcomes were nasopharyngitis, dry mouth, hypertension, constipation, headache, dyspepsia, urinary tract infection, dizziness, blurred vision, nausea, cardiovascular events, influenza, electrocardiogram QT prolonged, upper respiratory tract infection and high blood pressure. RESULTS: In all, 10 peer-reviewed trials comprising 6135 patients were identified. Compared with placebo, mirabegron 50mg had an unfavorable safety profile resulting in nasopharyngitis (OR, 1.54[95% credible interval, 1.05-2.25]; P=0.03. No statistical difference was found between mirabegron 50mg and placebo groups in other 14 outcomes. CONCLUSION: Mirabegron 50mg is further confirmed to be nearly as safe as placebo, expect for nasopharyngitis. Nasopharyngitis is associated with mirabegron 50mg monotherapy for patients with overactive bladder.

Accuracy of diagnostic tests for American tegumentary leishmaniasis: a systematic literature review with meta-analyses.

OBJECTIVES: To analyse the accuracy of American tegumentary leishmaniasis (ATL) diagnostic methods and evaluate the quality of the existing publications by means of a systematic review. METHODS: Diagnostic tests evaluated in at least two studies with common reference standards were included in the sensitivity and/or specificity meta-analyses. Quality and susceptibility to bias were analysed using the QUADAS-2 and STARD tools. RESULTS: The title and abstract of 3387 publications were evaluated after deduplication resulting from database searches. Thirty-eight studies were included in the review, and 26 of them had results inserted in meta-analyses. The diagnostic methods with the highest pooled sensitivity values were ELISA, polymerase chain reaction (PCR), indirect immunofluorescence reaction and Montenegro's intradermal reaction. Cytometry was assessed in only two studies and presented 100% sensitivity in both. Smear slide microscopy and histopathology showed low pooled values of sensitivity. For specificity, the highest pooled values were identified for PCR. High values were also identified for ELISA, except for studies in which the reference standard for defining negative participants included individuals with Chagas' disease or paracoccidioidomycosis, which also occurred for cytometry. IFR had lower specificities than ELISA. There was a predominance of case-control designs of phase 1 or 2 and only four studies were strongly recommended as evidence generators. Several reference standards were adopted, and different methods were assessed in a small number of studies. CONCLUSION: PCR showed the highest accuracy for the diagnosis of ATL, and its use should be encouraged in clinical practice. ELISA is recommended for the screening of suspected individuals, but the possibility of cross-reactions should be considered. New validation studies for the tests evaluated in few publications and studies of phase 3 with appropriate methods are needed.

OBJECTIFS: Analyser l'exactitude des méthodes de diagnostic de la leishmaniose tégumentaire américaine (LTA) et évaluer la qualité des publications existantes au moyen d'une analyse systématique. MÉTHODES: Les tests diagnostiques évalués dans au moins deux études avec des étalons de référence communs ont été inclus dans les méta-analyses de sensibilité et/ou de spécificité. La qualité et la sensibilité au biais ont été analysées à l'aide des outils QUADAS-2 et STARD. RÉSULTATS: Le titre et le résumé de 3387 publications ont été évalués après déduplication résultant de recherches dans la base de données. 38 études ont été incluses dans la revue et 26 d'entre elles ont eu des résultats inclus dans des méta-analyses. Les méthodes de diagnostic avec les valeurs de sensibilité poolées les plus élevées étaient ELISA, la réaction en chaîne par polymérase (PCR), la réaction d'immunofluorescence indirecte et la réaction intradermique du Monténégro. La cytométrie a été évaluée dans seulement deux études et présentait une sensibilité de 100% dans les deux. La microscopie et l'histopathologie sur lame de frottis ont montré de faibles valeurs poolées de sensibilité. Pour la spécificité, les valeurs poolées les plus élevées ont été identifiées pour la PCR. Des valeurs élevées ont également été identifiées pour l'ELISA, à l'exception des études dans lesquelles la norme de référence pour définir les participants négatifs incluait des individus atteints de la maladie de Chagas ou de paracoccidioïdomycose, qui s'est également produite pour la cytométrie. L'IFR avait des spécificités plus faibles que l'ELISA. Il y avait une prédominance des essais cas-témoins de phases 1 ou 2 et seules quatre études étaient fortement recommandées comme génératrices de preuves. Plusieurs normes de référence ont été adoptées et différentes méthodes ont été évaluées dans un petit nombre d'études. CONCLUSION: la PCR a montré la plus grande exactitude pour le diagnostic de l'ATL et son utilisation doit être encouragée dans la pratique clinique. L'ELISA est recommandé pour le dépistage des personnes suspectées, mais la possibilité de réactions croisées doit être considérée. De nouvelles études de validation des tests évalués dans quelques publications et des études de phase 3 avec des méthodes appropriées sont nécessaires.

Association of TP53 rs1042522 with cervical cancer in the sub-Saharan African population: a meta-analysis.

OBJECTIVE: TP53 plays a crucial role in preventing cancer development. Previous studies in sub-Saharan Africa (SSA) reported inconclusive findings for the association of the TP53 rs1042522 C > G variant with cervical cancer. We therefore performed a meta-analysis to summarise this association in the SSA population. METHODS: Online databases were searched to identify suitable articles according to the PRISMA guidelines. We included studies published in English or French that provided the sample sizes and genotype counts for both cases and controls and evaluated the association between TP53 rs1042522 and cervical cancer in the SSA population. A fixed-effect model was used to calculate the pooled odds ratio (OR) and 95% confidence intervals (95% CIs). RESULTS: A total of 699 cervical cancer cases and 1008 controls from eight studies in SSA were included in this meta-analysis. Women harbouring the variant G allele of the TP53 rs1042522 were at increased risk of cervical cancer in allelic (G vs. C; OR = 1.30, 95% Cl = 1.12-1.50), homozygous (GG vs. CC; OR = 1.62, 95% CI = 1.20-2.19) and recessive (GG vs. CG + GG; OR = 1.74, 95% CI = 1.34-2.25) genetic models. However, the dominant genetic model (CG + GG vs. CC; OR = 1.20, 95% CI = 0.96-1.48) was not significantly associated with cervical cancer. CONCLUSIONS: Our meta-analysis revealed that harbouring variant G allele of TP53 rs1042522 is associated with cervical cancer risk in the SSA population.

OBJECTIF: Le TP53 joue un rôle crucial dans la prévention du développement du cancer. Des études antérieures en Afrique subsaharienne (ASS) ont rapporté des résultats non concluants pour l'association de la variante TP53 rs1042522 C>G avec le cancer du col de l'utérus. Nous avons donc réalisé une méta-analyse pour résumer cette association dans la population SSA. MÉTHODES: Les bases de données en ligne ont été recherchées pour identifier les articles appropriés selon les directives PRISMA. Nous avons inclus des études publiées en anglais ou en français qui ont fourni la taille des échantillons et le nombre de génotypes pour les cas et les témoins et évalué l'association entre TP53 rs1042522 et le cancer du col de l'utérus dans la population SSA. Un modèle à effet fixe a été utilisé pour calculer le rapport de cotes combiné (OR) et les intervalles de confiance à 95% (IC95%). RÉSULTATS: Un total de 699 cas de cancer du col utérin et 1008 témoins de huit études en ASS ont été inclus dans cette méta-analyse. Les femmes hébergeant l'allèle variant G du TP53 rs1042522 présentaient un risque accru de cancer du col de l'utérus chez les modèles génétiques alléliques (G vs C; OR = 1,30, IC95%: 1,12-1,50), homozygotes (GG vs CC; OR = 1,62, IC95%: 1,20-2,19) et récessifs (GG vs.CG + GG; OR = 1,74, IC95%: 1,34-2,25). Cependant, le modèle génétique dominant (CG + GG vs CC; OR = 1,20, IC95%: 0,96-1,48) n'était pas significativement associé au cancer du col utérin. CONCLUSIONS: Notre méta-analyse a révélé que l'hébergement de l'allèle variant G de TP53 rs1042522 est associé au risque de cancer du col de l'utérus dans la population SSA.

Prevalence of multidrug-resistant tuberculosis in Latin America and the Caribbean: a systematic review and meta-analysis.

OBJECTIVES: To evaluate the prevalence of multidrug-resistant tuberculosis (MDR-TB) in individuals living in Latin America and the Caribbean (LAC). METHODS: We searched the MEDLINE, Embase and Literatura Latino Americana e do Caribe em Ciências da Saúde (Lilacs) databases until 08 August 2019 for all studies on the subject, without time or language restrictions. Original studies reporting the prevalence of infection with Mycobacterium tuberculosis resistant to isoniazid and rifampicin simultaneously (MDR) in LAC, the prevalence of resistance in cases with no previous treatment (new cases) and the prevalence of resistance in previously treated cases were selected. Considering the expected heterogeneity between studies, all analyses were performed using the random effects model, and heterogeneity was assessed using the I2 statistic. RESULTS: We included 91 studies from 16 countries. The estimated overall prevalence was 13.0% (95% CI 12.0-14.0%), and the heterogeneity between studies was substantial (I2  = 96.1%). In the subgroup analyses, it was observed that the prevalence of MDR-TB among new cases was 7.0% (95% CI 6.0-7.0%) and in previously treated cases was 26.0% (95% CI 24.0-28.0%). CONCLUSIONS: This review highlights multidrug resistance to antituberculosis drugs in LAC, indicating that prevention strategies have not been effective. Government institutions should invest heavily in strategies for early diagnosis and the rapid availability of effective treatments and prioritise adequate protection for health professionals. In addition, screening programmes should be adopted to prevent secondary cases.

OBJECTIFS: Evaluer la prévalence de la tuberculose multirésistante (TB-MDR) chez les personnes vivant en Amérique latine et dans les Caraïbes (ALC). MÉTHODES: Nous avons effectué des recherches dans les bases de données Medline, EMBASE et Literatura Latino Americana e do Caribe em Ciências da Saúde (Lilas) jusqu'au 08 août 2019 pour toutes les études sur le sujet, sans restriction de temps ou de langue. Des études originales faisant état de la prévalence de l'infection à Mycobacterium tuberculosis résistante à l'isoniazide et à la rifampicine simultanément (MDR) dans la région ALC, de la prévalence de la résistance dans les cas sans traitement antérieur (nouveaux cas) et de la prévalence de la résistance dans les cas précédemment traités ont été sélectionnées. Compte tenu de l'hétérogénéité attendue entre les études, toutes les analyses ont été effectuées à l' aide du modèle à effets aléatoires et l'hétérogénéité a été évaluée à l' aide de la statistique I2 . RÉSULTATS: Nous avons inclus 91 études de 16 pays. La prévalence globale était estimée à 13,0% (IC95%: 12,0%-14,0%) et l'hétérogénéité entre les études était importante (I2 = 96,1%). Dans les analyses des sous-groupes, il a été observé que la prévalence de la TB-MDR parmi les nouveaux cas était de 7,0% (IC95%: 6,0%-7,0%) et dans les cas précédemment traités de 26,0% (IC95%: 24,0%-28,0%). CONCLUSIONS: Cette revue met en évidence la multirésistance aux médicaments antituberculeux dans la région ALC, indiquant que les stratégies de prévention n'ont pas été efficaces. Les institutions gouvernementales devraient investir massivement dans les stratégies de diagnostic précoce et la disponibilité rapide de traitements efficaces et accorder la priorité à une protection adéquate pour les professionnels de la santé. De plus, des programmes de dépistage devraient être adoptés pour prévenir les cas secondaires.

Effect of fenugreek consumption on serum lipid profile: A systematic review and meta-analysis.

Various studies have shown that Trigonella foenum-graecum (fenugreek) supplementation has lipid-lowering activity. This meta-analysis was performed to evaluate the effect of fenugreek supplementation on human serum lipid profile. Data sources were PubMed, EMBASE, Scopus, and Coherence library which were searched systematically from January 2000 up to December 2019. Inclusion criteria were randomized clinical trial (RCT) study design, at least one of lipid profile components (triglyceride [TG], total cholesterol [TC], low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol) levels measured before fenugreek use and one of the lipid components level reported as result. The pooled weighted mean difference (MD) and its 95% confidence interval (CI) were calculated and pooled using a random-effect model. Only articles published in English were considered. Fifteen RCTs involving 281 cases consumed fenugreek and 255 control cases in controlled group (11 articles) and 136 cases in uncontrolled group (4 articles) were analyzed in our study. Pooled data of indicated a significant impact of fenugreek supplementation on lowering TC (-1.13 [-1.88, -0.37]; p = .003), low-density lipoprotein (LDL) (-1.26 [-2.09, -0.43]; p = .003), and TG (-1.07 [-1.82, -0.33]; p = 0.005) and increasing the high-density lipoprotein (HDL) level (0.70 [0.07, 1.34]; p = .03) compared with the control group. There were no significant differences in TC, TG, and LDL between pre- and post-fenugreek studies in the noncontrolled studies however, the result of combination of four studies without control group showed a significant increase in mean HDL (0.81 [0.33,1.29]; p-value = .001). The results of subgroup analysis showed that the fenugreek reduced the TG and LDL and increases HDL levels in diabetic subjects more effectively. Fenugreek supplementation significantly improved lipid profile (LDL, TG, TC, and HDL). It could be considered as an effective lipid-lowering medicinal plant. Further high-quality studies are needed to firmly establish the clinical efficacy of the plant.

Acide hyaluronique intra articulaire dans la gonarthrose: une étude long-terme, ouverte, de Phase IV, avec analyse détaillée par stade de Kellgren-Lawrence.

INTRODUCTION: Les injections intra articulaires (IA) d'acide hyaluronique (HA) désignées sous le nom de viscosupplémentation (VS), sont fréquemment utilisées dans le traitement symptomatique de la gonarthrose (OA), une affection ostéo-articulaire chronique douloureuse et handicapante, qui touche une fraction importante de la population âgée. La sévérité de la gonarthrose est en général décrite par la classification en stades radiologiques de Kellgren-Lawrence (KL). La VS a été largement étudiée à travers de nombreux essais cliniques; cependant, les résultats sont rarement analysés en détail, en fonction du stade KL. MÉTHODE: Une étude ouverte importante, portant sur 1 177 patients souffrant de gonarthrose, fut réalisée de 2004 à 2007. Chaque patient a reçu un traitement de VS consistant en 3 injections d'ARTHRUM H 2% (LCA Pharmaceutical, Chartres, France). A l'inclusion, les patients ont été décrits par leur profil démographique, leur indice de masse corporelle (IMC), leur stade KL et leur état clinique selon les sous-scores douleur et fonction de l'indice Western Ontario and McMaster Universities (WOMAC). Les visites de suivi étaient à M3, M6 et M9 (mois) après la VS. Cette large base de données a été entièrement retraitée en 2019, de manière à fournir une analyse séparée par stade KL, et fut complétée par l'évaluation des taux de patients répondeurs (%) au traitement, selon l'Outcome Measures in Rheumatoid Arthritis Clinical Trials & Osteoarthritis Research Society International (OMERACT-OARSI). L'analyse fut menée à la fois sur les populations en intention de traiter (ITT) et per protocole (PP) ayant terminé l'étude. RÉSULTATS: En analyse ITT du critère principal, les variations du sous-score WOMAC A (douleur) depuis l'inclusion jusqu'à la fin de l'étude, ont été respectivement de 19,8 ; 19,8 ; 17,8 et 14,2, sur une échelle de 0-100, pour les patients des stades KL I à KL IV. En analyse PP dans les mêmes conditions, ces variations ont été de 20,6 ; 19,9 ; 17,1 et 11,7. Tous ces résultats étaient significatifs par rapport aux valeurs à l'inclusion (p<0.001) et cliniquement pertinents à chaque stade KL. Des améliorations significatives ont été également observées pour le sous-score WOMAC C (fonction), et pour les autres critères secondaires. Le taux de répondeurs OMERACT-OARSI variait de 72 à 82% pour les patients KL I à III à M6 et M9. Pour les patients KL IV, le maximum atteint a été 47.7% à M6. Les autres paramètres tels que le sexe, l'IMC ou l'âge, ne furent pas identifiés comme des facteurs de pronostic pour la réponse à la VS.

Reduced E-cadherin expression as a prognostic factor in non-muscle-invasive bladder cancer: A systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: The exact role of E-cadherin in non-muscle-invasive bladder cancer (NMIBC) is still unknown, and the aims of this study were to prove whether reduced E-cadherin expression can be a prognostic factor in patients with NMIBC. MATERIALS AND METHODS: A meta-analysis was conducted to assess the prognostic value of reduced E-cadherin expression in NMIBC. The PubMed, Embase and Web of Science databases were included in the study search. RESULTS: Fifteen studies with a total of 1538 NMIBC patients were included. The results showed that reduced E-cadherin expression was significantly associated with poor recurrence-free survival (RFS) (pooled HR 2.16, 95% CI 1.22-3.85) and progression-free survival (PFS) (pooled HR 1.91, 95% CI 1.52-2.40) in NMIBC patients. CONCLUSION: E-cadherin can be a prognostic factor for patients with NMIBC.

Zika transmission patterns: a meta-review.

OBJECTIVE: To assesses what is known and identify knowledge gaps for Zika virus (ZIKV) transmission patterns. METHODS: Meta-review searching the databases BioSys; Cochrane Infectious Diseases Group Specialised Register and Cochrane Central Register of Controlled Trials; EMBASE; Google Scholar; LILACS; MEDLINE (PubMed); Web of Science; and WHOLIS with the term 'ZIKA'. Systematic reviews and reviews specifying the search methods and describing potential modes of transmission were eligible for analysis. RESULTS: Of 5,401 hits for 'Zika', 44 studies were assessed and 11 included after applying in- and exclusion criteria: six systematic reviews and five reviews with specified methods, covering all ways of possible transmission. Results can be grouped into transmission routes with good evidence and agreement between the studies (evidence on vector, mother-to-child and sexual transmission) and transmission routes with limited evidence. Transmission by breastfeeding, intrapartum, by animal bites or laboratory-based remains inconclusive, as these routes are suggested by single studies only. The risk of transfusion transmission is described and public health measures for safe transfusion should be taken as available. CONCLUSION: Our results imply the need for public health measures to limit transmission via vectors, mother-to-child, sexual transmission and blood transfusion. Also needed are long-term prospective cohort studies covering periods of active Zika virus transmission and measuring epidemiological parameters to establish evidence on other routes of transmission; seroprevalence studies; transmission dynamics modelling and modelling health impacts by different modes of transmission.

OBJECTIF: Evaluer ce que l'on sait et identifier les lacunes dans les connaissances sur les profils de transmission du virus Zika (ZIKV). MÉTHODES: Méta-analyse de recherche dans les bases de données BioSys, Cochrane Infectious Diseases Specialised Register et le Registre Central Cochrane des Essais Contrôlés, EMBASE, Google Scholar, LILACS MEDLINE (PubMed), Web de la Science et WHOLIS avec le terme «Zika¼. Les revues systématiques et les revues spécifiant les méthodes de recherche et décrivant les modes de transmission potentiels étaient éligibles pour l'analyse. RÉSULTATS: Sur 5.401 résultats correspondant à «Zika¼, 44 études ont été évaluées et 11 incluses après application des critères d'inclusion et d'exclusion: 6 revues systématiques et 5 revues avec des méthodes spécifiées, couvrant tous les modes de transmission possibles. Les résultats peuvent être regroupés en voies de transmission avec des preuves solides et une concordance entre les études (preuves sur la transmission vectorielle, transmission mère-enfant et sexuelle) et les voies de transmission avec des preuves limitées. La transmission par l'allaitement, par voie intra-partum, par des morsures d'animaux ou via le laboratoire reste non conclusive, car ces voies ne sont suggérées que par des études uniques. Le risque de transmission par transfusion est décrit et des mesures de santé publique visant à garantir une transfusion sans danger doivent être prises dès que possible. CONCLUSION: Nos résultats insinuent la nécessité de prendre des mesures de santé publique pour limiter la transmission par le biais des vecteurs, la transmission mère-enfant, la transmission sexuelle et la transfusion sanguine. Des études de cohorte prospectives à long terme portant sur des périodes de transmission active du virus Zika et des mesures de paramètres épidémiologiques sont également nécessaires pour établir des preuves d'autres voies de transmission; des études de séroprévalence; la modélisation de la dynamique de transmission et la modélisation des impacts sur la santé par différents modes de transmission.

Interventions for the control of Aedes aegypti in Latin America and the Caribbean: systematic review and meta-analysis.

OBJECTIVE: To determine the effectiveness and degree of implementation of interventions for the control of Aedes aegypti in Latin America and the Caribbean (LAC) as reported in scientific literature. METHODS: We searched MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS, for experimental and observational studies, economic assessments and qualitative experiences carried out in LAC from 2000 to 2016. We assessed incidence and morbimortality of Aedes aegypti-related diseases and entomological indices: Breteau (containers), House, and Pupae per Person. We used GRADE methodology for assessing quality of evidence. RESULTS: Of 1826 records retrieved, 75 were included and 9 cluster randomised clinical trials could be meta-analysed. We did not identify any intervention supported by a high certainty of evidence. In consistency with qualitative evidence, health education and community engagement probably reduces the entomological indices, as do the use of insecticide-treated materials, indoor residual spraying and the management of containers. There is low certainty of evidence supporting the use of ovitraps or larvitraps, and the integrated epidemiological surveillance strategy to improve indices and reduce the incidence of dengue. The reported degree of implementation of these vector control interventions was variable and most did not extend to whole cities and were not sustained beyond 2 years. CONCLUSIONS: We found a general lack of evidence on effectiveness of vector control in the region, despite a few interventions that showed moderate to low certainty of evidence. It is important to engage and educate the community, apart from achieving the implementation of integrated actions between the health and other sectors at national and regional level.

OBJECTIF: Déterminer l'efficacité et le degré d'implémentation des interventions de lutte contre Aedes aegypti en Amérique latine et dans les Caraïbes (ALC), tels que décrits dans la littérature scientifique. MÉTHODES: Nous avons effectué des recherches dans MEDLINE, EMBASE, CENTRAL, SOCINDEX et LILACS pour des études expérimentales et d'observation, des évaluations économiques et des expériences qualitatives réalisées dans la région ALC de 2000 à 2016. Nous avons évalué l'incidence et la morbimortalité des maladies liées à Aedes aegypti et les indices entomologiques: Breteau (conteneurs), Maison et Pupe par Personne. Nous avons utilisé la méthodologie GRADE pour évaluer la qualité des données. RÉSULTATS: Sur 1.826 articles retrouvés, 75 ont été inclus et 9 essais cliniques randomisés en grappes ont pu être méta-analysés. Nous n'avons identifié aucune intervention étayée par une certitude élevée. De manière cohérente avec les preuves qualitatives, l'éducation pour la santé et la participation de la communauté réduisent probablement les indices entomologiques, de même que l'utilisation de matériaux traités à l'insecticide, la pulvérisation de résidus à l'intérieur et la gestion des conteneurs. Il existe peu de certitude quant aux données soutenant l'utilisation des ovitraps ou des larvitraps et de la stratégie de surveillance épidémiologique intégrée visant à améliorer les indices et à réduire l'incidence de la dengue. Le degré d'implémentation rapporté pour ces interventions de lutte antivectorielle était variable et la plupart ne s'étendaient pas à l'entièreté des villes et ne duraient pas plus de deux ans. CONCLUSIONS: Nous avons constaté un manque général de preuves sur l'efficacité de la lutte antivectorielle dans la région, malgré quelques interventions montrant une certitude modérée à faible. Il est important d'impliquer et d'éduquer la communauté, outre la mise en œuvre d'actions intégrées entre le secteur de la santé et d'autres secteurs aux niveaux national et régional.

Meta-analysis of mammary RNA seq datasets reveals the molecular understanding of bovine lactation biology.

A better understanding of the biology of lactation, both in terms of gene expression and the identification of candidate genes for the production of milk and its components, is made possible by recent advances in RNA seq technology. The purpose of this study was to understand the synthesis of milk components and the molecular pathways involved, as well as to identify candidate genes for milk production traits within whole mammary transcriptomic datasets. We performed a meta-analysis of publically available RNA seq transcriptome datasets of mammary tissue/milk somatic cells. In total, 11 562 genes were commonly identified from all RNA seq based mammary gland transcriptomes. Functional annotation of commonly expressed genes revealed the molecular processes that contribute to the synthesis of fats, proteins, and lactose in mammary secretory cells and the molecular pathways responsible for milk synthesis. In addition, we identified several candidate genes responsible for milk production traits and constructed a gene regulatory network for RNA seq data. In conclusion, this study provides a basic understanding of the lactation biology of cows at the gene expression level.

Maternal depression and infant attachment security: A meta-analysis.

The purpose of this study is to clarify the magnitude of the association between maternal depression and infant attachment nonsecurity, and to identify possible moderators of this relationship. An extensive literature search was conducted using multiple databases of both published and unpublished studies. A meta-analysis was conducted to determine the relationship between maternal depression and infant attachment security and to establish the effect size. The main findings from this meta-analysis, which included 42 studies, indicate that there is a small, yet significant, relationship between maternal depression and infant attachment nonsecurity. The rate of nonsecurity in infants of mothers with depression was approximately 20% higher than expected rates in a nonclinical population, and the association between depressive symptoms and nonsecurity was small, but significant. Infants of mothers with depression were nearly twice as likely to have a nonsecure attachment than were infants of healthy mothers. Depression measure and maternal sample source were identified as significant moderators of the odds ratio effect size. Results of this study demonstrate that there is a significant relationship between maternal depression and infant attachment nonsecurity, and suggest that interventions that focus on both maternal mental health and the attachment relationship are warranted.

Propósito: Clarificar la magnitud de las asociaciones entre la depresión materna y la falta de seguridad en la afectividad del infante, así como identificar posibles moderadores de esta relación. Métodos: Se llevó a cabo una extensa búsqueda de la literatura existente usando múltiples bancos de información tanto de estudios publicados como de los no publicados. Se realizó un meta-análisis para determinar la relación entre la depresión materna y la seguridad de la afectividad del infante y establecer la dimensión del efecto. Resultados: Los principales resultados de este meta-análisis, el cual incluyó 42 estudios, indicaron que existe una pequeña pero significativa relación entre la depresión materna y la falta de seguridad en la afectividad del infante. La tasa de falta de seguridad en infantes de madres con depresión fue aproximadamente 20% más alta que la tasa esperada en una población no clínica, y la asociación entre los síntomas depresivos y la falta de seguridad fue pequeña pero significativa. Los infantes de madres con depresión estuvieron casi dos veces más propensos a tener una afectividad no segura que los infantes de madres saludables. Se identificó la medida de depresión y la fuente del grupo muestra materno como moderadores significativos de la dimensión del efecto en las posibilidades promedio. Conclusiones: Los resultados de este estudio demuestran que existe una significativa relación entre la depresión materna y la falta de seguridad en la afectividad del infante, y sugieren que las intervenciones que se enfocan tanto en la salud mental materna como en la relación de afectividad están garantizadas.

But: Clarifier la magnitude du lien entre la dépression maternelle et l'insécurité de l'attachement du nourrisson, et identifier des facteurs de modération possibles de cette relation. Méthodes: Une importante recherche sur les recherches a été faite en utilisant plusieurs bases de données comprenant à la fois des études publiées et des études non publiées. Une méta-analyse a été faite afin de déterminer la relation entre la dépression maternelle et la sécurité de l'attachement du nourrisson et afin d'établir la taille de l'effet. Résultats: Les principaux résultats de cette méta-analyse, qui a porté sur 42 études, ont indiqué qu'il existe une relation petite et cependant importante entre la dépression maternelle et l'insécurité de l'attachement du nourrisson. Le taux d'insécurité chez les nourrissons de mère avec une dépression était lié à des taux environ 20% plus élevés que les taux attendus chez une population non-clinique, et le lien entre les symptômes dépressifs et la non-sécurité était limité mais important. Les nourrissons de mères avec une dépression étaient presque deux fois plus à même d'avoir un attachement insécure que les nourrissons de mères en bonne santé. La mesure de dépression et la source de l'échantillon maternel ont été identifiées comme étant des facteurs de modération importants de l'ampleur des effets des rapports de cote. Conclusions: Les résultats de cette étude démontrent qu'il existe une relation importante entre la dépression maternelle et l'insécurité de l'attachement du nourrisson, et suggèrent que les interventions qui mettent l'accent à la fois sur la santé mentale maternelle et la relation d'attachement sont justifiées.

Impact of drinking water, sanitation and handwashing with soap on childhood diarrhoeal disease: updated meta-analysis and meta-regression.

OBJECTIVES: Safe drinking water, sanitation and hygiene are protective against diarrhoeal disease; a leading cause of child mortality. The main objective was an updated assessment of the impact of unsafe water, sanitation and hygiene (WaSH) on childhood diarrhoeal disease. METHODS: We undertook a systematic review of articles published between 1970 and February 2016. Study results were combined and analysed using meta-analysis and meta-regression. RESULTS: A total of 135 studies met the inclusion criteria. Several water, sanitation and hygiene interventions were associated with lower risk of diarrhoeal morbidity. Point-of-use filter interventions with safe storage reduced diarrhoea risk by 61% (RR = 0.39; 95% CI: 0.32, 0.48); piped water to premises of higher quality and continuous availability by 75% and 36% (RR = 0.25 (0.09, 0.67) and 0.64 (0.42, 0.98)), respectively compared to a baseline of unimproved drinking water; sanitation interventions by 25% (RR = 0.75 (0.63, 0.88)) with evidence for greater reductions when high sanitation coverage is reached; and interventions promoting handwashing with soap by 30% (RR = 0.70 (0.64, 0.77)) vs. no intervention. Results of the analysis of sanitation and hygiene interventions are sensitive to certain differences in study methods and conditions. Correcting for non-blinding would reduce the associations with diarrhoea to some extent. CONCLUSIONS: Although evidence is limited, results suggest that household connections of water supply and higher levels of community coverage for sanitation appear particularly impactful which is in line with targets of the Sustainable Development Goals.

Risk of active tuberculosis among people with diabetes mellitus: systematic review and meta-analysis.

OBJECTIVE: To assess the risk of active TB in people with DM and the factors associated with this risk. METHODS: Systematic review and meta-analysis. We searched the literature for studies that reported the effect of DM on TB controlled for the effect of age. Studies that had not established the diagnosis of DM prior to detecting active TB were excluded. Study quality was assessed by Newcastle-Ottawa scale and we conducted a meta-analysis using random-effects models. RESULTS: Of 14 studies (eight cohort and six case-control studies) that involved 22 616 623 participants met the selection criteria and were included in the analysis. There was substantial variation between studies in the estimates of the effect of DM on TB. However, the pooled estimates from seven high-quality studies showed that diabetic people have a 1.5-fold increased risk of developing active TB vs. those without DM (95%CI 1.28-1.76), with relatively small heterogeneity (I2  = 44%). The increased risk of TB was observed predominantly among DM populations with poor glycaemic control. CONCLUSION: There is evidence suggesting an increased risk of developing TB among people with DM, and that improving glycaemic control in DM patients would reduce the risk of developing TB. An integrated approach is needed to control the dual burden of DM and TB.

Ileal conduit vs orthotopic neobladder: Which one offers the best health-related quality of life in patients undergoing radical cystectomy? A systematic review of literature and meta-analysis.

INTRODUCTION: Orthotopic neobladder (ONB) and ileal conduit (IC) are the most commonly practiced techniques of urinary diversion (UD) after radical cystectomy (RC) in bladder cancer patients. Data in the literature is still discordant regarding which UD technique offers the best HR-QoL. OBJECTIVE: The objective was to compare HR-QoL in patients undergoing ONB and IC after RC, through a systematic review of the literature and meta-analysis. MATERIAL AND METHODS: We performed a literature search of PubMed, ScienceDirect, CochraneLibrary and ClinicalTrials.Gov in September 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were subdomains' scores of Bladder Cancer Index BCI: urinary function (UF), urinary bother (UB), bowel function (BF), bowel bother (BB), sexual function (SF) and sexual bother (SB). Continuous outcomes were compared using weighted means differences, with 95% confidence intervals. The presence of publication bias was examined by funnel plots. RESULTS: Four studies met the inclusion criteria. The pooled results demonstrated better UF and UB scores in IC patients: differences were -18.17 (95% CI: -27.49, -8.84, P=0.0001) and -3.72 (95% CI: -6.66, -0.79, P=0.01) respectively. There was no significant difference between IC and ONB patients in terms of BF and BB. SF was significantly better in ONB patients: the difference was 12.7 (95% CI, 6.32, 19.08, P<0.0001). However no significant difference was observed regarding SB. CONCLUSION: This meta-analysis of non-randomized studies demonstrated a better HR-QoL in urinary outcomes in IC patients compared with ONB patients.
