AbstractThere is a growth in the demand for clinical practice to be evidence based. Recent years have seen a rise in the number of randomized controlled clinical trials (RCTS). Such trials while acknowledged as the gold standard for evidence can be difficult to perform in surgical specialities. We have recently identified a low proportion of RCTS in the otolaryngology literature. Our aim was to identify any trend in the number of published RCTS within the ENT literature over a 30-year period and to identify which areas of our speciality lend themselves to this form of study design. A Medline search of 10 prominent journals published between 1966 and 1995 was performed. Two hundred and ninety-six RCTS were identified. Only five were published before 1980. Two hundred (71 per cent) of RCTS were in the areas of otology and rhinology. An encouraging trend is seen in RCTS within ENT literature.

PURPOSE Breast cancer is the most common malignancy in women worldwide. In Nigeria, it accounts for 22.7% of all new cancer cases among women. Evidence-based medicine (EBM) entails using the results from healthcare research to enhance the clinical decision-making process and develop evidence-based treatment guidelines. Level 1 and 2 studies, such as randomized controlled trials, meta-analyses, and systematic reviews of randomized controlled trials, yield more robust types of evidence. This study reviewed the levels of evidence of breast cancer publications in Nigeria. METHODS We conducted an electronic literature search of all studies published on breast cancer in Nigeria from January 1961 to August 2019. We reviewed all the articles found under the search term “Breast Cancer in Nigeria” on medical databases. RESULTS Our search identified 2,242 publications. One thousand two hundred fifty duplicates were removed, and 520 were excluded. A total of 472 articles were considered eligible for this review. Most of these articles were case series or reports (30.7%), qualitative studies (15.7%), followed by cross-sectional studies (13.3%), laboratory studies (12.9%), case-control studies (6.1%), case reports (7%), and cohort (5.7%). CONCLUSION Breast cancer research in Nigeria is yet to produce much evidence of the types considered to best support EBM. The scarcity of data hampers the implementation of EBM in Nigeria. Currently, most treatment guidelines are adapted from those developed in other countries, despite genetic differences among populations and different environmental influencing factors.

Objectives: Not all practice guidelines on oral treatment of Type 2 diabetes were consistent with available evidences. Our aim was to explore the necessity of following the new clinical evidences in treatment of diabetes mellitus Type 2 in clinical practice and the availability of randomized controlled trials in literature used. Methods: Cross-sectional interview survey of 20 physicians in the Internal Medicine Departments in Althawra Teaching Hospital, University of Sana'a, Yemen, to understand the drug used in T2DM in regards to the clinically evidenced trials. The three commonly used literatures were studied for the availability of randomized controlled trials s and the systematic reviews. Results: Examples of drugs to be considered in special correlation and contradiction were metformin and thiazolidinediones (rosi-, pioglitazone). Fear of lactic acidosis was seen in 45% of physicians. Ischemic Heart disease and failure represent the commonest cause of glitazones avoidance, especially for rosiglitazone (100% vs. 50% for pioglitazone). Example of drugs used were with no agreements of their benefit are gabapentin (35%) and neurobion (30%) for neuropathy prevention. In the side effect consideration, metformin was still considered dangerous, and B-blockers hesitation in ischemic heart disease prevention. The main source of information used by physicians was Davidson's Medicine, British national formulary and pharmaceutical marketing leaflets. Conclusions: Inconsistency between the tested physicians may be improved by better access and implementation of evidence-based therapy and guidelines in T2DM.

AbstractChildren with parents suffering from a psychiatric disorder are at higher risk for developing a mental disorder themselves. This systematic review and meta-analysis of randomized controlled trials aims to evaluate the efficacy of psychosocial interventions to prevent negative mental health outcomes in the offspring of parents with mental illness. Eight electronic databases, grey literature and a journal hand-search identified 14 095 randomized controlled trials with no backward limit to June 2021. Outcomes in children included incidence of mental disorders (same or different from parental ones) and internalizing and externalizing symptoms at post-test, short-term and long-term follow-up. Relative risks and standardized mean differences (SMD) for symptom severity were generated using random-effect meta-analyses. Twenty trials were selected (pooled n = 2689 children). The main therapeutic approaches found were cognitive-behavioural therapy and psychoeducation. A significant effect of interventions on the incidence of mental disorders in children was found with a risk reduction of almost 50% [combined relative risk = 0.53, 95% confidence interval (CI) 0.34–0.84]. Interventions also had a small but significant effect on internalizing symptoms at post-test (SMD = −0.25, 95% CI −0.37 to −0.14) and short-term follow-up (−0.20, 95% CI −0.37 to −0.03). For externalizing symptoms, a decreasing slope was observed at post-test follow-up, without reaching the significance level (−0.11, 95% CI −0.27 to 0.04). Preventive interventions targeting the offspring of parents with mental disorders showed not only a significant reduction of the incidence of mental illness in children, but also a diminution of internalizing symptoms in the year following the intervention.

Background: N-of-1 trials offer an innovative approach to delivering personalized clinical care together with population-level research. While increasingly used, these methods have raised some statistical concerns in the healthcare community. Methods: We discuss concerns of selection bias, carryover effects from treatment, and trial data analysis conceptually, then rigorously evaluate concerns of effect sizes, power and sample size through simulation study. Four variance structures for patient heterogeneity and model error are considered in a series of 5000 simulated trials with 3 cycles, which compare aggregated N-of-1 trials to parallel randomized controlled trials (RCTs) and crossover trials. Results: Aggregated N-of-1 trials outperformed both traditional parallel RCT and crossover designs when these trial designs were simulated in terms of power and required sample size to obtain a given power. N-of-1 designs resulted in a higher type-I error probability than parallel RCT and cross over designs when moderate-to-strong carryover effects were not considered or in the presence of modeled selection bias. However, N-of-1 designs allowed better estimation of patient-level random effects. These results reinforce the need to account for these factors when planning N-of-1 trials. Conclusion: N-of-1 trial designs offer a rigorous method for advancing personalized medicine and healthcare with the potential to minimize costs and resources. Interventions can be tested with adequate power with far fewer patients than traditional RCT and crossover designs. Operating characteristics compare favorably to both traditional RCT and crossover designs.
