Randomized controlled trial(RCT) is considered to represent the gold standard for evaluating the efficacy of interventions and has been widely used to evaluate the clinical efficacy of traditional Chinese medicine(TCM). However, there are unique challenges in implementing RCT in TCM. Patients seeking TCM treatment often have preferences for TCM due to the unsatisfactory therapeutic effect of western medicine, their personal intolerance, and their rejection of certain drugs, medical devices, or surgery. Patients are generally reluctant to be randomly assigned to a group, making it challenging to enroll patients in the control group of western medicine during the implementation of RCT in TCM. This has become a prominent problem restricting the implementation of RCT in TCM and needs to be solved urgently. Therefore, this paper introduced commonly used research designs used in solving the problem of enrolling patients in control group during the implementation of RCT in TCM, including Zelen design, partially randomized patient preference trial(PRPP), single-arm objective performance criteria(OPC), cohort studies, single-arm clinical trials using real world data(RWD) alone as the external control group, and the design method based on RWD-augmented control group samples in RCT. The paper outlined the definitions and principles of these methods, evaluated their advantages, disadvantages, and applicable scenarios, and explored their applications in the TCM field, so as to offer insights for solving the difficulty in enrolling patients in the control group during the implementation of RCT in TCM.

patient recruitment, we surveyed whether the hospitals were using 2-mSv CT in usual practice.RESULTS: The analyses included responses from 579 participants (203 attendings and 376 trainees; 221 radiologists, 196 emergency physicians, and 162 surgeons). Regarding the willingness to immediately change their standard practice to 2-mSv CT, 158 (27.3%), 375 (64.8%), and 46 (7.9%) participants responded as “yes” (consistently), “partly” (selectively), and “no”, respectively. Willingness varied considerably across the hospitals, but only slightly across the participants' departments or job titles. Willingness was significantly associated with attendings (p = 0.004), intention to maintain the dedicated appendiceal CT protocol (p < 0.001), belief in compelling evidence on the carcinogenic risk of conventional-dose CT radiation (p = 0.028), and hospitals having more than 1000 beds (p = 0.031). Fourteen of the 20 hospitals kept using 2-mSv appendiceal CT in usual practice after the trial.CONCLUSION: Despite the extensive efforts over the years of this clinical trial, many care providers were willing to use 2-mSv CT selectively or not willing to use.]]>

Immune Network 2020;20(1):10-
Immune checkpoint inhibitors (ICIs) have shown remarkable benefit in the treatment of patients with non-small-cell lung cancer (NSCLC) and have emerged as an effective treatment option even in the first-line setting. ICIs can block inhibitory pathways that restrain the immune response against cancer, restoring and sustaining antitumor immunity. Currently, there are 4 PD-1/PD-L1 blocking agents available in clinics, and immunotherapy-based regimen alone or in combination with chemotherapy is now preferred option. Combination trials assessing combination of ICIs with chemotherapy, targeted therapy and other immunotherapy are ongoing. Controversies remain regarding the use of ICIs in targetable oncogene-addicted subpopulations, but their initial treatment recommendations remained unchanged, with specific tyrosine kinase inhibitors as the choice. For the majority of patients without targetable driver oncogenes, deciding between therapeutic options can be difficult due to lack of direct cross-comparison studies. There are continuous efforts to find predictive biomarkers to find those who respond better to ICIs. PD-L1 protein expressions by immunohistochemistry and tumor mutational burden have emerged as most well-validated biomarkers in multiple clinical trials. However, there still is a need to improve patient selection, and to establish the most effective concurrent or sequential combination therapies in different NSCLC clinical settings. In this review, we will introduce currently used ICIs in NSCLC and analyze most recent trials, and finally discuss how, when and for whom ICIs can be used to provide promising avenues for lung cancer treatment.

Penile prosthesis implantation is the gold standard of surgical therapy for patients with medication-refractory erectile dysfunction. However, this umbrella definition includes significant heterogeneity and associated risk profiles that should be candidly discussed and addressed perioperatively. Factors associated with operative success and patient satisfaction are often surgery specific; however, risk profiling via patient selection, preoperative optimization, proper device selection, and intraoperative consideration are highly correlated. Some examples of common risk profiles include comorbidity(ies) such as cardiovascular disease, diabetes mellitus, prior abdominal surgery, Peyronie's disease, and psychological risk factors. Similarly, integration of surgeon- and patient-amenable characteristics is key to decreasing risk of infection, complication, and need for revision. Finally, patient risk profiling provides a unique context for proper device selection and evidence-based intraoperative considerations.

The testicular prosthesis can be an afterthought for providers when performing an orchiectomy for testicular cancer, torsion, atrophic testis, or trauma. However, data suggest that patients find the offer of a testicular prosthesis and counseling regarding placement to be extremely important from both a pragmatic and a psychosocial perspective. Only two-thirds of men undergoing orchiectomy are offered an implant at the time of orchiectomy and of those offered about one-third move forward with prosthesis placement. The relatively low acceptance rate is in stark contrast with high patient satisfaction and low complication rates for those who undergo the procedure. The most common postoperative patient concerns are minor and involve implant positioning, size, and weight. Herein, we provide an up-to-date review of modern preoperative evaluation, patient selection, expectation management, surgical technique, and expected outcomes for testicular prostheses.

PURPOSE: Inhaled corticosteroids (ICSs) are often considered an empirical therapy in the management of patients with cough. However, ICS responsiveness is difficult to interpret in daily clinical practice, as the improvements may include placebo effects or self-remission. We aimed to evaluate ICS and placebo treatment effects in adult patients with cough. METHODS: Electronic databases were searched for studies published until June 2018, without language restriction. Randomized controlled trials reporting the effects of ICSs compared with placebo in adult patients with cough were included. Random effects meta-analyses were conducted to estimate the treatment effects. Therapeutic gain was calculated by subtracting the percentage change from baseline in the cough score in the ICS treatment group from that in the placebo treatment group. RESULTS: A total of 9 studies were identified and 8 studies measuring cough severity outcomes were included for meta-analyses. Therapeutic gain from ICSs ranged from −5.0% to +94.6% across the studies included; however, it did not exceed +22%, except for an outlier reporting very high therapeutic gains (+45.6% to +94.6%, depending on outcomes). Overall ICS treatment effects in cough severity outcomes were small-to-moderate (standardized mean difference [SMD], −0.38; 95% confidence interval [CI], −0.54, −0.23), which were comparable between subacute and chronic coughs. However, pooled placebo treatment effects were very large in subacute cough (SMD, −2.58; 95% CI, −3.03, −2.1), and modest but significant in chronic cough (SMD, −0.46; 95% CI, −0.72, −0.21). CONCLUSIONS: Overall therapeutic gain from ICSs is small-to-moderate. However, placebo treatment effects of ICS are large in subacute cough, and modest but still significant in chronic cough. These findings indicate the need for careful interpretation of ICS responsiveness in the management of cough patients in the clinic, and also for rigorous patient selection to identify ICS-responders.

9.Appropriate treatment modality for solitary small hepatocellular carcinoma: Radiofrequency ablation vs. resection vs. transplantation?
Clinical and Molecular Hepatology 2019;25(4):354-359
There has been controversy regarding the first-line treatment modality for the patients who have small solitary hepatocellular carcinoma (HCC); radiofrequency ablation (RFA) or percutaneous ethanol injection (PEI), surgical hepatic resection (HR) and liver transplantation (LT). For selection of treatment modality of HCC, it should be considered of hepatic reservoir function as well as the tumor stage. If the liver function is good enough, HR may be the first choice regardless of the tumor size. However, recent studies comparing RFA with resection showed comparable outcome and similar survival rates. RFA, HR and LT provide good outcome for patients who have small HCCs. RFA would be desired in patients who have below 3.0 cm in size and low alpha-fetoprotein (<200 ng/mL). However, in small HCC with high tumor marker, HR should be considered. Better patient selection for the ‘resection first’ approach and early detection of recurrence can achieve better outcomes of the salvage LT strategy. Another benefit of resection first strategy is that it make possible to do enlist of LT for patients before recurrence at high risk of HCC recurrence after resection on the basis of pathologic aggressiveness, microvascular invasion and/or satellites nodule. They should be applied appropriately according to the tumor size, location, tumor markers and underlying liver parenchymal disease.

Menopause is associated with the onset of climacteric symptoms due to low estradiol levels, which may cause insufficient maturation of the vaginal mucosa. Vitamin D may regulate the growth and differentiation of cells that are adversely affected due to low estradiol levels, thereby restoring vaginal health. The objective of this systematic review, the first on this subject, was to investigate the effect of vitamin D on the vaginal health of menopausal women. PubMed, Embase, Scopus, Web of Science, and Google Scholar databases and reference lists of hand-searched articles were searched for published studies from February 2000 to November 2018. The selection criteria were as follows: randomized or quasi-randomized trials that compared the effects of vitamin D or related compounds, alone or with calcium, on vaginal health (growth and differentiation of epithelial cells, dryness, acidity [pH]) outcomes in menopausal women. The methodological quality of these studies was examined using the Cochrane tool checklist by two independent investigators, following which the data were extracted. Of six examined studies, two showed that vitamin D administration improved the growth and differentiation of vaginal epithelial cells, improved vaginal pH, and decreased vaginal dryness in menopausal women. Although the level of evidence for the effects of vitamin D on vaginal health is low in our study, we concluded that vitamin D may improve the vaginal health of women, especially during menopause.
