Background and Objective: Recent RCTs have failed to show benefit of intra-arterial therapy (IAT). We sought to determine whether these trials have affected the views and practice of IAT amongst stroke-treating physicians. Methods: An international web-based survey was sent to 753 stroke-treating physicians across the globe. Results: 322 physicians responded (43% rate); 25% were interventionalists; 80% practice in 24/7 IAT capable centers (fig 1). IAT volume per year prior to the RCTs (fig 2) has now decreased according to nearly half of the respondents. Physicians are now more selective (59%) while a third made no changes in pursuing IAT and 6% “do not pursue IAT anymore” (fig 3). Although 76% still perceive IAT is effective under certain criteria, two thirds said they feel “less obligated” to offer IAT. When asked about the RCTs, respondents felt the devices were outdated (36%), patient selection methods were “not optimal” (32%), recanalization rates could have been better (25%) or the trials should have been better designed (20%). Interestingly, centers currently enrolling in IAT trials intervene on large proportions of patients outside of studies (fig 4). The single most important factor in patient selection is shown in fig 5. Over half prefer a CT modality for patient selection; while 16% chose MRI and 11% use clinical criteria only when deciding to pursue IAT. Finally, three quarters of the contributors said that patients should be taken to IAT only in the context of clinical trials to test its efficacy, 21% said IAT should be continued “outside of trials” and only 3% pronounced it not useful (fig 6). Conclusion: While the results of recent RCTs have changed the views of stroke treating physicians, IAT continues to be practiced worldwide. The majority of our respondents is more selective and awaits results of new trials with the stent retrievers and better selection methods. Despite endorsing the practice of IAT only within trials, over half are still treating cases outside studies.

The current public health crisis has highlighted the need to accelerate healthcare innovation. Despite unwavering levels of cooperation among academia, industry, and policy makers, it can still take years to bring a life-saving product to market. There are some obvious limitations, including lack of blinding or masking and small sample size, which render the results less applicable to the real world. Traditional randomized controlled trials (RCTs) are lengthy, expensive, and have a low success rate. There is a growing acknowledgement that the current process no longer fully meets the growing healthcare needs. Advances in technology coupled with proliferation of telehealth modalities, sensors, wearable and connected devices have paved the way for a new paradigm. Virtual randomized controlled trials (vRCTs) have the potential to drastically shorten the clinical trial cycle while maximizing patient-centricity, compliance, and recruitment. This new approach can inform clinical trials in real time and with a holistic view of a patient’s health. This paper provides an overview of virtual clinical trials, addressing critical issues, including regulatory compliance, data security, privacy, and ownership.

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.

<p><strong>BACKGROUND:</strong> Lack of intimacy is currently the main concern rather than main concern of the experts in psychology and counseling. It is considered as one of the most important causes for divorce and as such to improve marital intimacy a great number of interventions have been proposed in the literature. Intimacy training and counseling make the couples take effective and successful steps to increase marital intimacy. No study has reviewed the interventions promoting marital intimacy after marriage. Thus, this review study aimed to classify the articles investigating the impact of interventional programs on marital intimacy after marriage.</p><p><strong>SEARCH METHODS:</strong> In April 2015, we performed a general search in Google Scholar search engines, and then we did an advanced search the databases of Science Direct, ProQuest, SID, Magiran, Irandoc, Pubmed, Scopus, <a href="http://www.cochranelibrary.com/">Cochrane Library</a>, and Psych info; Cumulative Index to Nursing and Allied Health Literature (CINAHL). Also, lists of the references of the relevant articles were reviewed for additional citations. Using Medical Subject Headings (MESH) keywords: Intervention (Clinical Trials, Non-Randomized Controlled Trials, Randomized Controlled Trials, Education), intimacy, marital (Marriage) and selected related articles to the study objective were from 1995 to April 2015. Clinical trials that evaluated one or more behavioral interventions to improve marital intimacy were reviewed in the study.</p><p><strong>MAIN RESULTS:</strong> 39 trials met the inclusion criteria. Eleven interventions had follow-up, and 28 interventions lacked follow-up. The quality evidence for 22 interventions was low, for 15 interventions moderate, and for one intervention was considered high. Findings from studies were categorized in 11 categories as the intimacy promoting interventions in dimensions of emotional, psychological, physical, sexual, temporal, communicational, social and recreational, aesthetic, spiritual, intellectual intimacy, and total intimacy.</p><p><strong>AUTHORS’ CONCLUSIONS:</strong> Improving and promoting communication, problem solving, self-disclosure and empathic response skills and sexual education and counseling in the form of cognitive-behavioral techniques and based on religious and cultural context of each society, an effective step can be taken to enhance marital intimacy and strengthen family bonds and stability. Health care providers should consider which interventions are appropriate to the couple characteristics and their relationships.</p>

Importance. COVID-19 has resulted in massive production, publication and wide dissemination of clinical studies trying to identify effective treatments. However, several widely touted treatments failed to show effectiveness in large well-done randomized controlled trials (RCTs). Objective. To evaluate for COVID-19 treatments that showed no benefits in subsequent large RCTs how many of their most-cited clinical studies had declared favorable results for these interventions. Methods. Scopus (last update December 23, 2021) identified articles on lopinavir-ritonavir, hydroxycholoroquine/azithromycin, remdesivir, convalescent plasma, colchicine or interferon (index interventions) that represented clinical trials and that had received >150 citations. Their conclusions were assessed and correlated with study design features. The ten most recent citations for the most-cited article on each index intervention were examined on whether they were critical to the highly-cited study. Altmetric scores were also obtained. Findings. 40 articles of clinical studies on these index interventions had received >150 citations (7 exceeded 1,000 citations). 20/40 (50%) had favorable conclusions and 4 were equivocal. Highly-cited articles with favorable conclusions were rarely RCTs while those without favorable conclusions were mostly RCTs (3/20 vs 15/20, p=0.0003). Only 1 RCT with favorable conclusions had sample size >160. Citation counts correlated strongly with Altmetric scores, in particular news items. Only 9 (15%) of 60 recent citations to the most highly-cited studies with favorable or equivocal conclusions were critical to the highly-cited study. Conclusion. Many clinical studies with favorable conclusions for largely ineffective COVID-19 treatments are uncritically heavily cited and disseminated. Early observational studies and small randomized trials may cause spurious claims of effectiveness that get perpetuated.

Background: There is no uniform treatment for pathological scars, including keloids and hypertrophic scars, in clinic currently. Previously, multiple randomized controlled trials have examined the clinical efficacy of different treatments. Nonetheless, the results are inconsistent, and many treatments have not been directly compared. This makes it difficult to conclude which approach is more favorable, in terms of efficacy and safety, for the treatment of pathological scarring. This study aimed at evaluating the efficacy of different injection and topical treatment strategies for hypertrophic scar and keloid.Methods: Relevant literature from PubMed, Medline, Embase, Scopus, the Cochrane Central Register of Controlled Trials (CCRCT), and WHO International Clinical Trials Registry Platform (WHO-ICTRP) were searched, from database inception through November 2020. Randomized clinical trials evaluating different treatment strategies of pathological scars, including triamcinolone acetonide (TAC), verapamil (VER), 5-fluorouracil (5-FU), botulinum toxin A (BTA), bleomycin (BLM), and silicone gels were included in the study.Results: The network meta-analysis included a total of 2,009 patients from 29 studies. A network meta-analysis of injection and topical treatment strategies showed that the efficacy of TAC combined with BTA was best in the treatment of pathological scars. Combination therapies of TAC with 5-FU and TAC with BTA significantly improved the clinical efficiency. However, there was no statistically significant difference between other treatment strategies. The order of efficacy predicted by the surface under the cumulative ranking (SUCRA) curve was as follows: TAC+BTA (82.2%) &gt; TAC+5-FU (69.8%) &gt; BTA (67.3%) &gt; 5-FU+silicone (59.4%) &gt; TAC+silicone (58.3%) &gt; 5-FU (49.8%) &gt; BLM (42.0%) &gt; TAC (26.7%) &gt; VER (26.2%) &gt; silicone (18.3%). There was no publication bias revealed based on the funnel diagram.Conclusion: This study recommends intralesional injection of TAC-BTA and TAC-5-FU combined therapies. But for patients who cannot tolerate the side effects, the use of silicone gels in combination with TAC is recommended. However, these conclusions need to be further confirmed by more randomized controlled trials.

Opioid addiction is a chronic brain disorder characterized by a series of withdrawalsymptoms in behavioral, psychological, and neurobiological manifestations.Withdrawal symptoms are the main causeof relapse after periods of abstinence; thus,the treatment is focused on abstinence symptoms. Due to most of all types of opioidagonist drugs carry a potential for addiction and exacerbation of withdrawalsymptoms, nondrug methods have great potentials i n clinical applications.Electro acupuncture (EA), as a novel nonpharmacological approach, combined withmethadone has a long term positive efficacy on treating addict ion . Therefore, we designed a protocol to evaluate the adjuvant effect of EA for treating withdrawalsymptoms of opioid addiction addiction.MethodTo review reports of relevant clinical trials, we will searchEnglish language databases(EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials) andChinese databases (Chinese Biomedical Lit eratures, China National KnowledgeInfrastructure, Wanfang, and VIP). We will collect documents from the earliestpossible date up t to May 2020. We will also search online trial registries such as ClinicalTrials.gov (ClinicalTrials.gov/), the European Medicine Agency(www.ema.europa.eu/ema/), and WHO International Clinical Trials Registry Platform(www.who.int/ictrp). We will select randomized controlled trials RCT forwithdrawal from opioid addiction involving EA methadone and methadone alonetreatment. W e will use psychological assessment scales to evaluate treatment majoroutcomes which include numerous components such as OWS, VAS, HAMD, HAMA;then u rinalysis and m ethadone dosage also will be measure as the additional outcomes.Finally, RevMan5 software will be used for literature quality evaluation and dataana lysis.Result: To evaluate the efficacy of EA in combination therapy by observing the outcomes of corresponding scale, urinalysis and decreasing methadone.Conclusion: This protocol will be used to evaluate the efficacy and safety of EA in combination with methadone in treatment of opioid addiction withdrawal symptomsAbbreviationsOpioid dependence, OWS=Opiate Withdrawal Scale, VAS=Craving Visual Analog Scale, PWSS=Post-withdrawal symptoms Scale, HAMD=Hamilton Depression Scale, HAMA=Hamilton Anxiety Scale, RCTs =Randomized Controlled Trials, EA=Electrical Acupuncture, PRISMA=Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
