RESUMO
BACKGROUND: Financial relationships with drug and medical device companies may impact quality of care and academic research. However, little is known when and how these financial relationships develop among newly independent physicians who recently completed from residency or fellowship programs in internal medicine (IM). OBJECTIVE: To compare patterns of industry payments among IM graduates. DESIGN: Retrospective, observational cohort study. SUBJECTS: IM graduates from residency or fellowship programs between January 2015 and December 2019. MAIN MEASURES: We analyzed Open Payments reports made between July 2015 and June 2021 to recent graduates of U.S. Accreditation Council for Graduate Medical Education (ACGME)-accredited residency and fellowship programs in IM. The primary outcome was general payments accepted by these physicians, stratified by procedural (i.e., critical care medicine/pulmonary medicine, cardiac/cardiovascular disease, and gastroenterology) and non-procedural (i.e., infectious disease, general internal medicine, and other specialties) subspecialties. The secondary outcomes included general payments stratified by sex and age at residency or fellowship training completion. KEY RESULTS: There were 41,669 IM physicians with a median age of 33.0 years. In the first 3 years after completion, the proportion of physicians accepting any general payments was 72.6%, 91.9%, and 86.8% in Critical Care Medicine/Pulmonary Medicine, Cardiac/Cardiovascular Disease, and Gastroenterology, compared to 56.1%, 52.6%, and 52.3% in Infectious Disease, General Internal Medicine, and Other Specialties (p<0.0001). After adjusting for confounding variables, the procedural group showed an increased hazard ratio (HR) for accepting any general payments and at least $5000 of general payments compared to the non-procedural group. The HRs of accepting any general payments in the procedural subspecialty were 2.26 (95% CI, 2.11-2.42) and 2.83 (95% CI, 2.70-2.97) in female and male physicians, respectively (p-value < 0.0001). CONCLUSION: Industry financial relationships among newly independent physicians in IM exist immediately after completion of training and are influenced by subspecialty, sex, and age.

BACKGROUND AND OBJECTIVES: Few studies were evaluated the effect of blindness on outcome in animal models, though a potential effect of blinding has been reported in clinical trials. We evaluated the effects of adipose tissue-derived stem cells (ADSCs) on cavernous nerve injury (CNI)-induced erectile dysfunction (ED) in the rat and examined how proper blinding of the outcome assessor affected treatment effect. METHODS AND RESULTS: We searched in Pubmed, EMBASE, Cochrane and Web of Science databases from inception to January 2019. We included CNI animal model, randomized controlled experiments, and ADSC intervention. Erectile function and structural changes were assessed by intracavernous pressure and mean arterial pressure (ICP/MAP) ratios, neuronal nitric oxide synthase (nNOS) levels, cavernous smooth muscle and collagen (CSM/collagen) ratios, and cyclic guanosine monophosphate (cGMP). RESULTS: Nineteen studies were included in the final meta-analysis. The ICP/MAP ratio of the ADSC treatment group increased compared to the control group (SMD=1.33, 95%CI: 1.11â¼1.56, I2=72%). The nNOS level (SMD=2.29, 95%CI: 1.74â¼2.84, I2=75%), CSM/collagen (SMD=2.57, 95%CI: 1.62â¼3.52; I2=85%), and cGMP (SMD=2.96, 95%CI: 1.82â¼4.10, I2=62%) were also increased in the ADSC treatment group. Preplanned subgroup analysis was conducted to explore the source of heterogeneity. Five studies with blinded outcome assessment were significantly less effective than the unblinded studies (SMD=1.33, 95%CI: 0.86â¼1.80; SMD=1.81, 95%CI: 1.17â¼2.46, respectively). CONCLUSIONS: ADSCs might be effective in improving erectile function and structural change in CNI-induced ED. However, non-blinded outcome assessors might cause detection bias and overestimate treatment efficacy. Therefore, the ADSC efficacy must be further evaluated with a rigorous study design to avoid bias.
RESUMO
Background: Recently, the application of smartphone in medical field has received great attention.Introduction: The objective of this study was to compare the effectiveness of smartphone-based and conventional pedometer-based exercise monitoring systems in promoting home exercise among prostate cancer patients.Methods: Prostate cancer patients who have undergone surgery or androgen deprivation therapy were recruited. All participants were provided with physical activity goals based on their activities and were advised to achieve these goals during their home exercise period. The intervention group was instructed to use smartphone application to record their activities; they also received weekly remote consultations based on the activity record from the application, without visiting a clinic. The control group was instructed to keep a written record of their daily activities based on pedometer readings; these records were checked by clinicians during follow-up visits. The uptake, adherence, and completion rates of two groups were compared by intention-to-treat analysis. Changes in physical function during the exercise period were analyzed.Results: In total, 100 patients were recruited (smartphone: 5 and pedometer: 50). No significant differences were detected between groups in rates of uptake (80.0% vs. 88.0%, p = 0.28), adherence (92.5% vs. 79.5%, p = 0.12), or completion (76.0% vs. 86.0%, p = 0.20). Physical functions were significantly improved in both groups.Conclusions: The smartphone-based exercise monitoring system and the pedometer yielded comparable results in promoting physical activity, as assessed by rates of uptake, adherence, and completion. Exercise monitoring was effective in improving physical functions, in both methods.

We aimed to assess the gender-specific associations between psychological factors and socioeconomic status (SES) and metabolic syndrome (MetS) in Korean adults. We examined 4,689 Korean adults aged 20-79 years who participated in the 2013 Korean National Health Examination and Nutrition Survey. With regard to SES, occupation status (none, manual, and nonmanual), marital status (single, married, divorced, and widowed), and psychological factors (detection of stress, depressive symptoms, and suicidal thoughts) were determined via questionnaires. Compared with married men, single and divorced men exhibited ORs (95% confidence interval [CIs]) for MetS of 0.45 (0.31-0.65) and 1.61 (1.02-2.55), respectively, after adjusting for covariates. However, this association was not significant in women. Compared with those in the lowest household income group and least educated group in women, the ORs for MetS in the highest income group and the most educated group were 0.63 (CI 0.46-0.86) and 0.46 (CI 0.32-0.67), respectively. Suicidal thoughts in men (OR 1.64, CI 1.03-2.61) and perceived stress in women (OR 1.26, CI 1.01-1.59) were associated with MetS. In this study, MetS has gender-specific associations with lower SES and psychological factors. Thus, gender-specific public health interventions based on SES and psychological factors are needed to prevent and treat MetS and reduce additional cardiovascular disease risk.

PURPOSE: To evaluate the safety and cost-effectiveness of a totally tubeless percutaneous nephrolithotomy (PCNL) by comparing the clinical outcomes and cost analysis between standard PCNL and totally tubeless PCNL for renal stones. PATIENTS AND METHODS: From June 2012 to September 2013, a total of 121 patients with renal stones who underwent totally tubeless or standard PCNL by two experienced surgeons were retrospectively evaluated by group. According to the surgeon's preference for the nephrostomy tube and/or ureteral stent, the present study was designed to be divided into Group 1 and Group 2. Group 1 was performed by one surgeon (H.J. Cho) who preferred a totally tubeless PCNL and Group 2 was performed by the other surgeon (S.H. Hong) who preferred a standard PCNL. We excluded bilateral renal stones, multiple approach, whole staghorn calculi, and previous renal surgery. Patient and stone characteristics, intraoperative and postoperative parameters, and cost analysis were compared between the two groups. RESULTS: There were no significant differences in the patient demographics between groups. Mean stone burden was 501.5±361.1 mm(2) in Group 1 v 535.2±353.1 mm(2) in Group 2 (P=0.651). Length of hospital stay (1.72±0.58 v 4.10±1.88 days, P<0.001), postoperative pain scores using a visual analog scale (day 0: P<0.001, day 1: P=0.002), and analgesia requirements (33.2±21.3 v 45.2±19.5 mg, P=0.005) for Group 1 v Group 2 showed significant differences. The stone-free rate was 86.4% v 89.8% in Group 1 and Group 2, respectively (P=0.609). There were no significant differences in overall complications between groups (P=0.213). Mean total medical treatment costs in Groups 1 and 2 were 2398.22±549.1 USD and 2845.70±824.2 USD, respectively (P=0.002). CONCLUSIONS: Many clinical outcomes in the totally tubeless PCNL showed comparable or better results than standard PCNL. We believe that totally tubeless PCNL is an acceptable, safe, and cost-effective alternative to standard PCNL for the treatment of renal stones.

OBJECTIVE: To compare multi-detector CT (MDCT) using 128-slice coronary CT angiography (Definition AS+, Siemens Medical Solution, Forchheim, Germany) with ECG-based maximum tube current modulation with echocardiography for the determination of left ventricular ejection fraction (LVEF), end-diastolic volume (EDV), end-systolic volume (ESV), as well as assessing coronary artery image quality and patient radiation dose. MATERIALS AND METHODS: Thirty consecutive patients (M:F = 20:10; mean age, 57.9 ± 11.4 years) were referred for MDCT for evaluation of atypical chest pain. EF, EDV and ESV were determined for both MDCT and echocardiography, and the correlation coefficients were assessed. Coronary artery segment subjective image quality (1, excellent; 4, poor) and radiation dose were recorded. RESULTS: Left ventricular EF, EDV, and ESV were calculated by MDCT and echocardiography and the comparison showed a significant correlation with those estimated by echocardiography (p < 0.05). Consistently, the LVEFs calculated by MDCT and echocardiography were not statistically different. However, LV, EDV and ESV from MDCT were statistically higher than those from echocardiography (p < 0.05). The average image quality score of the coronary artery segment was 1.10 and the mean patient radiation dose was 3.99 ± 1.85 mSv. CONCLUSION: Although LV volume was overestimated by MDCT, MDCT provides comparable results to echocardiography for LVEF and LVV, with a low radiation dose.
