Across 50 years of research, extensive efforts have been made to improve the effectiveness of psychotherapies for children and adolescents. Yet recent evidence shows no significant improvement in youth psychotherapy outcomes. In other words, efforts to improve the general quality of therapy models do not appear to have translated directly into improved outcomes. We used multilevel meta-analytic data from 502 randomized controlled trials to generate a bivariate copula model predicting effect size as therapy quality approaches infinity. Our results suggest that even with a therapy of perfect quality, achieved effect sizes may be modest. If therapy quality and therapy outcome share a correlation of .20 (a somewhat optimistic assumption given the evidence we review), a therapy of perfect quality would produce an effect size of Hedges’s g = 0.83. We suggest that youth psychotherapy researchers complement their efforts to improve psychotherapy quality by investigating additional strategies for improving outcomes.

Abstract. Borderline Intellectual Functioning (BIF) refers to a global IQ ranging from 71 to 84, and it represents a condition of clinical attention for its association with other disorders and its influence on the outcomes of treatments and, in general, quality of life and adaptation. Furthermore, its definition has changed over time causing a relevant clinical impact. For this reason, a systematic review of the literature on this topic can promote an understanding of what has been studied, and can differentiate what is currently attributable to BIF from that which cannot be associated with this kind of intellectual functioning. Using Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria, we have conducted a review of the literature about BIF. The results suggest that this condition is still associated with mental retardation, and only a few studies have focused specifically on this condition.

Objective: Infertility has a severe impact on quality of life and mental health. This condition could be exacerbated by the existence of comorbid medical disease, like endometriosis. The aim of this critical narrative review is the examination of the state of the art about the quality of life and mental health in infertile women with endometriosis. Methods: We performed a rigorous and systematic search for studies on multiple electronic databases. A total of 6 papers were included in the review and were subjected to interpretative and critical narrative synthesis. Results and Discussion: Major findings are resumed in the following points: (a) infertile women with endometriosis when compared to infertile ones without endometriosis show higher depression, stress perception, and anxiety, and lower general quality of life; (b) quality of life specifically related to infertility is similar among women with and without endometriosis and seems to be related to personality and beliefs factors; (c) giving birth to a child is related to better mental quality of life; (d) during assisted reproductive treatment (ART) stimulation, infertile women with endometriosis have a decrease of dysmenorrhea and dyspareunia; (e) satisfaction of ART is related to the number of attempts, treatment accomplishment and pregnancy test outcomes. Clinical implications of these findings and suggestions for future researches were discussed. Conclusion: Concluding, it is crucial to assess the psychological factors related to endometriosis and infertility to reduce the impact of these diseases on quality of life and mental health, provide adequate support to these patients, improve their satisfaction and increase the change to get pregnant.

BACKGROUND Psoriasis is a complex disease associated with multiple comorbidities, including metabolic syndrome and leaky gut syndrome. Dietary lifestyle interventions have been reported to affect the disease in terms of lesional severity. It remains unclear how diets affect these comorbidities and the general health in psoriasis patients. Modified Intermittent Fasting (MIF) on 2 non-consecutive days has shown beneficial effects on metabolic parameters. A significant advantage of MIF over the currently investigated dietary changes is its feasibility. OBJECTIVE Here, we aim to study the effects of MIF on skin, gut and metabolic health in psoriasis patients. METHODS A two-arm pilot prospective cross-over randomized control trial (RCT) will be performed in 20 patients with psoriasis as a pilot study. Patients will be randomized 1:1 to either start with MIF and subsequent regular diet for 12 weeks each or to start with regular diet and subsequent MIF for 12 weeks each. The following parameters will be assessed: demographics, disease phenotype, medical and familial history, psoriasis severity, dermatology-specific and general quality of life, nutritional and physical habits, mental and intestinal health, intestinal and cutaneous integrity, inflammatory and metabolic markers, and satisfaction. RESULTS The aim is to uncover the effects of MIF on psoriasis severity and gut health integrity through clinical and molecular investigation. More precisely, we want to map the evolution of the different markers in response to MIF as compared to the regular diet, such as psoriasis severity, permeability and inflammation. CONCLUSIONS Understanding how dietary lifestyles can affect epithelial lineages such as the skin and gut, will greatly improve our understanding on the development of psoriasis and may pose a non-pharmacological venue for treatments.

In 2017, a National Academies of Sciences, Engineering, and Medicine (NASEM) report comprehensively evaluated the body of evidence regarding cannabis health effects through the year 2016. The objectives of this study are to identify and map the most recently (2016–2019) published literature across approved conditions for medical cannabis and to evaluate the quality of identified recent systematic reviews, published following the NASEM report. Following the literature search from 5 databases and consultation with experts, 11 conditions were identified for evidence compilation and evaluation: amyotrophic lateral sclerosis, autism, cancer, chronic noncancer pain, Crohn’s disease, epilepsy, glaucoma, human immunodeficiency virus/AIDS, multiple sclerosis (MS), Parkinson’s disease, and posttraumatic stress disorder. A total of 198 studies were included after screening for condition-specific relevance and after imposing the following exclusion criteria: preclinical focus, non-English language, abstracts only, editorials/commentary, case studies/series, and non-U.S. study setting. Data extracted from studies included: study design type, outcome definition, intervention definition, sample size, study setting, and reported effect size. Few completed randomized controlled trials (RCTs) were identified. Studies classified as systematic reviews were graded using the Assessing the Methodological Quality of Systematic Reviews-2 tool to evaluate the quality of evidence. Few high-quality systematic reviews were available for most conditions, with the exceptions of MS (9 of 9 graded moderate/high quality; evidence for 2/9 indicating cannabis improved outcomes; evidence for 7/9 indicating cannabis inconclusive), epilepsy (3 of 4 graded moderate/high quality; 3 indicating cannabis improved outcomes; 1 indicating cannabis inconclusive), and chronic noncancer pain (12 of 13 graded moderate/high quality; evidence for 7/13 indicating cannabis improved outcomes; evidence from 6/7 indicating cannabis inconclusive). Among RCTs, we identified few studies of substantial rigor and quality to contribute to the evidence base. However, there are some conditions for which significant evidence suggests that select dosage forms and routes of administration likely have favorable risk-benefit ratios (i.e., epilepsy and chronic noncancer pain). The body of evidence for medical cannabis requires more rigorous evaluation before consideration as a treatment option for many conditions, and evidence necessary to inform policy and treatment guidelines is currently insufficient for many conditions.

Objective: To evaluate all available evidence on the prediction of rotational tooth movements with aligners. Data sources: Seven databases of published and unpublished literature were searched up to 4 August 2020 for eligible studies. Data selection: Studies were deemed eligible if they included evaluation of rotational tooth movement with any type of aligner, through the comparison of software-based and actually achieved data after patient treatment. Data extraction and data synthesis: Data extraction was done independently and in duplicate and risk of bias assessment was performed with the use of the QUADAS-2 tool. Random effects meta-analyses with effect sizes and their 95% confidence intervals (CIs) were performed and the quality of the evidence was assessed through GRADE. Results: Seven articles were included in the qualitative synthesis, of which three contributed to meta-analyses. Overall results revealed a non-accurate prediction of the outcome for the software-based data, irrespective of the use of attachments or interproximal enamel reduction (IPR). Maxillary canines demonstrated the lowest percentage accuracy for rotational tooth movement (three studies: effect size = 47.9%; 95% CI = 27.2–69.5; P < 0.001), although high levels of heterogeneity were identified (I2: 86.9%; P < 0.001). Contrary, mandibular incisors presented the highest percentage accuracy for predicted rotational movement (two studies: effect size = 70.7%; 95% CI = 58.9–82.5; P < 0.001; I2: 0.0%; P = 0.48). Risk of bias was unclear to low overall, while quality of the evidence ranged from low to moderate. Conclusion: Allowing for all identified caveats, prediction of rotational tooth movements with aligner treatment does not appear accurate, especially for canines. Careful selection of patients and malocclusions for aligner treatment decisions remain challenging.

AbstractMany Intensive Care (ICU) survivors experience long lasting impairments in physical and psychological health as well as social functioning. The objective of our study was to evaluate these effects up to 10 years after ICU discharge. We performed a long-term prospective cohort study in patients admitted for longer than 48 h in a medical-surgical ICU. We evaluated health-related quality of life (HRQOL) before ICU admission using the Short-form-36 (SF-36), at ICU discharge, at hospital discharge and at 1, 2, 5 and 10 years follow up (all by patients). Changes in HRQOL were assessed based on linear mixed modeling. We included a total of 749 patients (from 2000 to 2008). During 10 years 475 (63.4%) patients had died, 125 (16.7%) patients were lost to follow up and 149 (19.9%) patients could be evaluated. The mean scores of four HRQOL dimensions (i.e., physical functioning (p < 0.001; mean 54, SD 32, effect size 0.77, 95% CI [0.54–1.0]), role-physical (p < 0.001; mean 44, SD 47, effect size 0.65, 95% CI [0.41–0.68] general health (p < 0.001; mean 52, SD 27, effect size 0.48; 95% CI 0.25–0.71) and social functioning (p < 0.001; mean 72, SD 32, effect size 0.41, 95% CI [0.19–0.64]) were still lower 10 years after ICU discharge compared with pre-admission levels (n = 149) and with an age reference population. Almost all SF-36 dimensions changed significantly over time from ICU discharge up to 10 years after ICU discharge. Over the 10 year follow up physical functioning of medical-surgical ICU survivors remains impaired compared with their pre-admission values and an age reference population. However, effect sizes showed no significant differences suggesting that surviving patients largely regained their age-specific HRQOL at 10 years.

Reciprocal teaching is an instructional procedure designed to teach students cognitive strategies that might lead to improved reading comprehension. The learning of cognitive strategies such as summarization, question generation, clarification, and prediction is supported through dialogue between teacher and students as they attempt to gain meaning from text. This article is a review of sixteen studies on reciprocal teaching, which include published studies found in journal articles and unpublished studies indexed in Dissertation Abstracts International. All the studies included in this review were quantitative in methodology. When standardized tests were used to assess comprehension, the median effect size, favoring reciprocal teaching, was .32. When experimenter-developed comprehension tests were used, the median effect size was .88. We also discuss the role of cognitive strategies in enhancing comprehension, the strategies that were most helpful, instructional approaches for teaching cognitive strategies, the quality of the dialogue during reciprocal teaching, and suggestions for future research and practice.
