Abstract Introduction Electronic data capture (EDC) tools can improve data quality gathered in clinical trials and may be more cost-effective than paper forms. However, limited data is available on the adoption of EDC tools in randomized controlled trials (RCT) conducted in India. Methods We invited investigators of registered randomized controlled trials in India to an online survey. The questionnaire included questions on the use of EDC (or alternative data capture methods) and features available. An EDC sophistication level (ranging from 1–6) was computed from the responses obtained. Respondents were also asked about barriers to the implementation of EDC in their setting. The EDC adoption rate (EAR) was defined as the proportion of clinical trials where EDC with a sophistication level of 2 or more was used. Multivariable logistic regression was used to identify factors that predicted EDC adoption. Results Responses were received for 400 trials, with an EAR of 27.5% (95% confidence intervals : 23.4–32.1%, n = 110). The number of sites influenced EDC adoption (odds ratio : 1.26, 95% CI : 1.12–1.47, p = 0.001) on multivariable analysis. EAR did not increase over time. The key barriers identified for not using an EDC were lack of technical support (170, 63.0%) and software cost (132, 48.9%). Conclusion The survey shows a low EAR in randomized trials registered in India. The barriers identified in the survey would need systematic solutions to improve the EAR in the future.

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.

Clinical trials are tests of safety and efficacy for drugs, vaccines, and diagnostics. Methods by with which trials are conducted include randomized controlled trials (RCTs) and equivalence studies. Randomized controlled trials compare an experimental compound with a placebo, or a previously existing drug, seeking to establish safety and/or efficacy. RCTs can also be conducted on social interventions or policies. According to current standards, trials are conducted in phases, cumulatively including more participants. So called phase I trials are “first-in-man” studies, prior to which animal studies have been conducted. Phases II and III include a higher number of study participants, often in thousands across the world. After phase III, marketing permission is sought—phases IV and V are used to promote the products and gather further evidence of side effects. Trials are also conducted to compare the equivalence of existing and remanufactured products, extend patents of the patent holder, and gain a hold of a new market, resulting in what is at times called “me-too”-drugs. Trials are conducted by public/global health researchers, pharmaceutical companies, and public-private partnerships all of which entail a complex web of actors. Anthropological literature exploring clinical trials has increased since the 2000s and the field reflects a global increase of overseas research by various biomedical actors. Clinical trials are not a new phenomenon, but their recent trajectory and shifting geographical locations has rendered them an object of inquiry. The increase is a consequence of multiple processes including global regulatory changes, emergence of new bilateral actors, and the overall development in countries like India and China that have increased their capacity for knowledge production. Within anthropology, the interest has coincided with and compounded research on globalization and global assemblages that has focused on webs and networks of technologies, ethics, and financial actors. Knowledge production processes have also illuminated the “ontological turn” in anthropology that has explored practices that give rise to objects, materiality, and biology. Following practices that construct pharmaceuticals illuminates the ways in which life itself, bodies, and biologies are socially constructed. Such approach, while not always explicitly, takes inspiration from Bruno Latour’s Actor-Network Theory and science and technology studies. Knowledge production processes are not devoid of power, and a major concern in the literature is the potential for exploitation of research participants, researchers, and local research cultures. In sites where global health research is conducted, health systems are often poor, and strongly divided between public and private health-care providers. Anthropology in/of clinical trials has engendered social scientists’ roles in working also in collaboration with medical researchers and thinking about the social relationships and ethics of international research, justice and universality of values, how to promote the interests and concerns of communities, and how indeed research bioethical regulation itself is a product of neoliberalization of health research.

ABSTRACT Background Clinical trials evaluating the effect of calcium supplementation on bone loss in lactating women have been small, with inconsistent results. Objectives We aimed to determine the effect of calcium supplementation on bone mineral density (BMD) in lactating women. Methods An electronic search of databases was conducted from inception to January 2020. Two authors screened studies, extracted data, and assessed the risk of bias of eligible studies. Percentage change in BMD was pooled using random-effects models and reported as weighted mean differences (WMDs) with 95% CIs. Risk of bias was assessed using the Cochrane risk of bias tool. Results Five randomized controlled trials including 567 lactating women were included. All had a high risk of bias. Mean baseline calcium intake ranged from 562 to 1333 mg/d. Compared with control groups (placebo/no intervention), calcium supplementation (600/1000 mg/d) had no significant effect on BMD at the lumbar spine (WMD: 0.74%; 95% CI: −0.10%, 1.59%; I2 = 47%; 95% CI: 0%, 81%; n = 527 from 5 trials) or the forearm (WMD: 0.53%; 95% CI: −0.35%, 1.42%; I2 = 55%; 95% CI: 0%, 85%; n = 415 from 4 trials). BMD at other sites was assessed in single trials: calcium supplementation had a small to moderate effect on total-hip BMD (WMD: 3.3%; 95% CI: 1.5%, 5.1%) but no effect on total body or femoral neck BMD. Conclusions Overall, the meta-analysis indicates that calcium supplementation does not provide clinically important benefits for BMD in lactating women. However, there was adequate dietary intake before supplementation in some studies, and others did not measure baseline calcium intake. Advising lactating women to meet the current recommended calcium intakes (with supplementation if dietary intake is low) is warranted unless new high-certainty evidence to the contrary from robust clinical trials becomes available. More research needs to be done in larger samples of women from diverse ethnic and racial groups. This systematic review was registered at www.crd.york.ac.uk/prospero as CRD42015022092.
