The Association of Subspecialty and Sex with Industry Payments to Internal Medicine Physicians Who Recently Completed Training.

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.

Comparison of analgesic effectiveness between nefopam and propacetamol in living kidney donors following rectus sheath block after hand-assisted living donor nephrectomy: a prospective, randomized controlled trial.

BACKGROUND: Nefopam and propacetamol are the most commonly used analgesics in postoperative multimodal analgesic regimens. Distinct mechanisms are involved in each drug's anti-nociceptive effects. No studies have compared pain relief efficacy between the two drugs in patients undergoing transplantation surgery. Here, we investigated whether the administration of nefopam or propacetamol to healthy living kidney donors who underwent rectus sheath block (RSB) for parietal pain could reduce the subsequent opioid dose necessary to produce adequate analgesia. METHODS: This prospective, randomized controlled trial included 72 donors undergoing elective hand-assisted living donor nephrectomy into two groups: propacetamol (n = 36) and nefopam (n = 36). Intraoperative RSB was performed in all enrolled donors. The primary outcome was the total volume of intravenous opioid-based patient-controlled analgesia (PCA) used on postoperative day 1 (POD 1). Additionally, the Numeric Rating Scale scores for flank (visceral) and umbilicus (parietal) pain at rest and during coughing were compared, and the Korean adaptation of the Quality of Recovery-15 Questionnaire (QoR-15 K) was evaluated on POD 1. RESULTS: Both groups had similar preoperative and intraoperative characteristics. On POD 1, the total amount of PCA infusion was significantly lower in the nefopam group than in the propacetamol group (44.5 ± 19.3 mL vs. 70.2 ± 29.0 mL; p < 0.001). This group also reported lower pain scores at the flank and umbilical sites and required fewer rescue doses of fentanyl in the post-anesthesia care unit. However, pain scores and fentanyl consumption in the ward were comparable between groups. The QoR-15 K scores were similar between groups; there were substantial improvements in breathing, pain severity, and anxiety/depression levels in the nefopam group. The incidences of postoperative complications, including sweating and tachycardia, were similar between groups. CONCLUSION: Compared with propacetamol, nefopam provides a greater analgesic effect for visceral pain and enhances the effects of blocks that reduce the opioid requirement in living kidney donors with parietal pain managed by RSB. TRIAL REGISTRATION: The trial was registered prior to patient enrollment in the clinical trial database using the Clinical Research Information Service (registration no. KCT0007351 , Date of registration 03/06/2022).

Integrated Bioinformatics Analysis Identified ASNS and DDIT3 as the Therapeutic Target in Castrate-Resistant Prostate Cancer.

Many studies have demonstrated the mechanisms of progression to castration-resistant prostate cancer (CRPC) and novel strategies for its treatment. Despite these advances, the molecular mechanisms underlying the progression to CRPC remain unclear, and currently, no effective treatments for CRPC are available. Here, we characterized the key genes involved in CRPC progression to gain insight into potential therapeutic targets. Bicalutamide-resistant prostate cancer cells derived from LNCaP were generated and named Bical R. RNA sequencing was used to identify differentially expressed genes (DEGs) between LNCaP and Bical R. In total, 631 DEGs (302 upregulated genes and 329 downregulated genes) were identified. The Cytohubba plug-in in Cytoscape was used to identify seven hub genes (ASNS, AGT, ATF3, ATF4, DDIT3, EFNA5, and VEGFA) associated with CRPC progression. Among these hub genes, ASNS and DDIT3 were markedly upregulated in CRPC cell lines and CRPC patient samples. The patients with high expression of ASNS and DDIT3 showed worse disease-free survival in patients with The Cancer Genome Atlas (TCGA)-prostate adenocarcinoma (PRAD) datasets. Our study revealed a potential association between ASNS and DDIT3 and the progression to CRPC. These results may contribute to the development of potential therapeutic targets and mechanisms underlying CRPC progression, aiming to improve clinical efficacy in CRPC treatment.

Oral anticoagulants and concurrent rifampin administration in tuberculosis patients with non-valvular atrial fibrillation.

BACKGROUND: Evidence and guidelines for Non-vitamin K antagonist oral anticoagulants (NOACs) use when prescribing concurrent rifampin for tuberculosis treatment in patients with non-valvular atrial fibrillation (NVAF) are limited. METHODS: Using the Korean National Health Insurance Service database from January 2009 to December 2018, we performed a population-based retrospective cohort study to assess the net adverse clinical events (NACE), a composite of ischemic stroke or systemic embolism and major bleeding, of NOACs compared with warfarin among NVAF patients taking concurrent rifampin administration for tuberculosis treatment. After a propensity matching score (PSM) analysis, Cox proportional hazards regression was performed in matched cohorts to investigate the clinical outcomes. RESULTS: Of the 735 consecutive patients selected, 465 (63.3%) received warfarin and 270 (36.7%) received NOACs. Among 254 pairs of patients after PSM, the crude incidence rate of NACE was 25.6 in NOAC group and 32.8 per 100 person-years in warfarin group. There was no significant difference between NOAC and warfarin use in NACE (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.48-1.14; P = 0.172). Major bleeding was the main driver of NACE, and NOAC use was associated with a statistically significantly lower risk of major bleeding than that with warfarin use (HR, 0.63; 95% CI, 0.40-1.00; P = 0.0499). CONCLUSIONS: In our population-based study, there was no statically significant difference in the occurrence of NACE between NOAC and warfarin use. NOAC use may be associated with a lower risk of major bleeding than that with warfarin use.

Safety and efficacy of immediate heparin reversal with protamine after complex percutaneous coronary intervention.

BACKGROUND: Compared to simple percutaneous coronary intervention (PCI), complex PCI is associated with higher bleeding and thrombotic risk. No previous study has evaluated the use of protamine after PCI with contemporary technologies. This study aimed to evaluate the safety and efficacy of manual compression with and without protamine after transfemoral complex PCI. METHODS: We retrospectively analyzed 160 patients (protamine group, n = 92; non-protamine group, n = 68) who underwent complex PCI via the femoral artery. The primary outcome was a composite of in-hospital death, myocardial infarction, stent thrombosis, stroke/systemic embolism, bleeding requiring blood transfusion, and vascular access complications. RESULTS: The primary outcome was significantly lower in the protamine group than in the non-protamine group (4.3% vs. 17.6%; p = 0.006). This was driven mainly by the lower incidences of hematoma in the protamine group (3.3% vs. 13.2%, p = 0.020). Furthermore, the protamine group had a significantly shorter hospital stay than the non-protamine group (4.8 ± 3.7 days vs. 8.4 ± 8.3 days, p = 0.001). While > 90% of the patients had acute coronary syndrome, there were no incidences of myocardial infarction or stent thrombosis in either group. CONCLUSIONS: Among patients who underwent complex PCI via transfemoral access, immediate protamine administration was associated with a significantly lower rate of vascular access complications, especially hematoma, and shorter hospital stay than no protamine administration.

Implication of cystic fluid cytology of renal cell carcinoma on surgical practice.

OBJECTIVES: To evaluate the incidence of positive cystic fluid cytology and its risk factors in cystic renal cell carcinoma (RCC) addressing its implication on the current surgical practice. METHODS: All clinically diagnosed Bosniak III, IV cystic renal masses from March 2019 to August 2022 were studied prospectively. Database of patients' demographics and cystic tumor characteristics were recorded. Partial or radical nephrectomies were performed by either laparoscopic or robotic approach. Cystic fluid was collected right after specimen retrieval in the surgical field and examined by pathologist. Cytology results were compared to the demographic, perioperative variables using univariate and multivariate analysis. RESULTS: A total of 70 patients of histologically confirmed cystic RCC were included. Sixty seven patients underwent radical nephrectomy with laparoscopic or robotic approaches, while 3 patients underwent radical nephrectomy. There was no intraoperative cystic rupture or fluid spillage. Positive cystic fluid cytology findings were identified in 34 (48.6%) patients, while negative cystic fluid cytology were identified in 36 (51.4%) cases. Definite malignant cells were observed in 28 patients while the other six patients showed highly suspicious atypical cells. Histologically, 24 (70.8%) patients were proven clear cell RCC and 25 (73%) showed Fuhrman grade 1 or 2 in final histologic review in positive group. Univariate and multivariate regression analysis between positive and negative cytology groups showed that the presence of the malignant cells in cystic fluid was significantly associated with patients' age (> 55 years) and Bosniak grade of cystic tumor (p < 0.05). CONCLUSIONS: Definite malignant cells in cystic fluid cytology were observed through our study. Additionally, patients' age (> 55 years) and Bosniak grade were the significant risk factors of positive cytology in cystic RCC. Therefore, necessity of meticulous manipulation of cystic renal tumors, despite their clinical features, should not be underemphasized to avoid the least possible tumor cell seeding in case of cystic rupture when operating such high risk of positive cytology.

Retroperitoneoscopic lumbar sympathectomy for the treatment of primary plantar hyperhidrosis.

BACKGROUND: Primary plantar hyperhidrosis (PPH) is an idiopathic disease, characterized by excessive sweating of the feet. It leads to significant disturbance in private and professional daily lifestyle, due to excessive sweating. The aim of this study is to present the safety, efficacy and procedures of retroperitoneoscopic lumbar sympathectomy (RLS) for treatment of PPH. METHODS: RLS was performed 60 times in 30 patients (18 men, 12 women) with PPH in our institution from May 2019 to October 2020. All procedures were carried out by laparoscopy with retroperitoneal approach. Clinical data including patient demographics and perioperative, postoperative outcomes were evaluated. Recurrence of symptoms, and any adverse effects of surgery were evaluated after 7 to 30 days in outpatient clinic, and thereafter every 6 months. RESULTS: Mean age of patients was 33.6 (± standard deviation 10.8) years. Fourteen and fifteen patients were previously treated with medical therapy or endoscopic thoracic sympathectomy (ETS) respectively. Mean preoperative quality of life (QoL) score of patients was 91.8 (VERY BAD), but postoperative 12 months (QoL) score decreased to 29.1 (MUCH BETTER). There was no serious postoperative complication. During the mean 22 months of follow-up period, no compensatory sweating was observed. CONCLUSIONS: RLS can be a safe and effective surgical treatment for severe PPH, especially for the patients with persistent plantar sweating even after conservative management and ETS. RLS also could be offered to surgeons who are familiar with retroperitoneal space anatomy as feasible surgical treatment for PPH.

Incidence and clinical impact of early recurrence of atrial tachyarrhythmia after surgical ablation for atrial fibrillation.

BACKGROUND: Atrial tachyarrhythmias (ATAs) are common within the 3-month blanking period after catheter ablation of atrial fibrillation (AF). However, little evidence is available regarding the current guidelines on the blanking period after surgical AF ablation. We investigate the incidence and significance of early recurrence of atrial tachyarrhythmia (ERAT) and evaluate the optimal blanking period after surgical AF ablation. METHODS: Data from 259 patients who underwent surgical AF ablation from 2009 to 2016 were collected. ERAT was defined as documented ATA episodes lasting for 30 s. A multivariate Cox proportional hazard model was constructed to evaluate the role of ERAT as a predictor of late recurrences (LR) for AF. RESULTS: In total, 127 patients (49.0%) experienced their last episodes of ERAT during the first (n = 65), second (n = 14), or third (n = 48) month of the 3-month blanking period (p < .001). One year freedom from ATAs was 97.8% in patients without ERAT compared with 95.4%, 64.3%, and 8.3% in patients with ERAT in the first, second, and third months after the index procedure, respectively (p < .001). Hazard ratios of LR according to the timing of the last episode of ERAT first, second, and third months after the procedure were 2.84, 16.70, and 119.75, respectively. CONCLUSIONS: The ERAT occurred in 49.0% of patients within the first 3 months after surgical ablation. The occurrence of ERAT within 3 months after surgical AF ablation was a significant independent predictor of LR. Hence, the currently accepted 3-month blanking period may be considered for redefining in patients with AF surgical ablation.

Incidence of Cardiovascular Events and Safety Profile of Prasugrel in Korean Patients With Acute Coronary Syndrome.

BACKGROUND: Dual antiplatelet therapy is commonly used for patients with acute coronary syndrome (ACS). This study aimed to evaluate the safety and efficacy of aspirin and prasugrel at standard dosages in Korean patients using clinical outcome data.Methods and Results:For this prospective multicenter phase IV post-marketing surveillance (PMS) study, ACS patients from 29 July 2012 to 28 July 2016 were recruited. Patients received aspirin at a dose of 75-150 mg daily and a standard dose of prasugrel. Bleeding events were recorded and summarized to evaluate safety. Data on adverse events (AEs) and composite events such as cardiovascular (CV) death, myocardial infarction (MI), and stroke were recorded and summarized to assess efficacy. Of the 3,283 patients recruited, data from 3,110 and 3,044 patients were included in the safety and efficacy analyses, respectively (median treatment duration, 172 days). The most frequently reported AE was ecchymosis (2.8%). The number of patients with major bleeding was 29/3,110 (0.93%). The discontinuation rate for any reason was 12.6%. The number of cases that ended in CV death, MI, stroke, stent thrombosis, or unplanned coronary revascularization was 26/3,044 (0.85%). CONCLUSIONS: The present results are similar to those observed in clinical trials where administration of low-dose aspirin plus prasugrel was associated with a low rate of major bleeding and CV events.

Factors Influencing the Treatment Effect of Superelastic Wire Orthonyxia for Nail Plate Deformity.

BACKGROUND: Orthonyxia is an effective, noninvasive treatment for transverse nail curvature deformity. OBJECTIVE: To discover the factors influencing treatment results of superelastic wire orthonyxia (SEWO). MATERIAL AND METHODS: A retrospective study was conducted using clinical records of patients treated with SEWO. A multiple linear regression model was used to explain the correlation between correction pace (% per week) and the other collected variables (patient age, sex, position of treated toe, wire diameter [WD, mm], wire residence time [WRT, weeks], nail plate thickness [PT, mm], baseline nail curvature index [NCI], number of previous treatments, and the correction pace of previous treatments [CPT, % per week]). A logistic regression model was used to identify risk factors for adverse effects. RESULTS: A total of 475 cases were collected from 197 patients. The correction pace was positively related to baseline NCI, WD, and correction pace in previous treatment. Also, it was negatively related to WRT and nail PT. No clinical factor was correlated with the occurrence of side effects. CONCLUSION: The correction pace of SEWO is affected by the baseline NCI, the diameter of the wire, nail PT, the CPT, and the WRT.

Comparison of the impact of propofol versus sevoflurane on early postoperative recovery in living donors after laparoscopic donor nephrectomy: a prospective randomized controlled study.

BACKGROUND: Enhancing postoperative recovery of the donor is important to encourage living kidney donation. We investigated the effects of anesthetic agents (intravenous [IV] propofol versus inhaled [IH] sevoflurane) on the quality of early recovery of healthy living kidney donors after hand-assisted laparoscopic nephrectomy (HALN) under analgesic intrathecal morphine injection. METHODS: This single-center, prospective randomized controlled study enrolled 80 living donors undergoing HALN from October 2019 to June 2020 at Seoul St. Mary's Hospital. Donors were randomly assigned to the IV propofol group or IH sevoflurane group. To measure the quality of recovery, we used the Korean version of the Quality of Recovery-40 questionnaire (QoR-40 K) on postoperative day (POD) 1, and ambulation (success rate, number of footsteps) 6-12 h after surgery and on POD 1. The pain score for the wound site, IV opioid requirement, postoperative complications including incidences of nausea/vomiting, and length of in-hospital stay were also assessed. RESULTS: The global QoR-40 K score and all subscale scores (physical comfort, emotional state, physical independence, psychological support, and pain) were significantly higher in the IV propofol group than in the IH sevoflurane group. The numbers of footsteps at all time points were also higher in the IV propofol group. Donors in the IV propofol group had a lower incidence of nausea/vomiting, and a shorter hospitalization period. CONCLUSIONS: Total IV anesthesia with propofol led to better early postoperative recovery than that associated with IH sevoflurane.

Delayed remnant kidney function recovery is less observed in living donors who receive an analgesic, intrathecal morphine block in laparoscopic nephrectomy for kidney transplantation: a propensity score-matched analysis.

BACKGROUND: This study analyzed remnant kidney function recovery in living donors after laparoscopic nephrectomy to establish a risk stratification model for delayed recovery and further investigated clinically modifiable factors. PATIENTS AND METHODS: This retrospective study included 366 adult living donors who underwent elective donation surgery between January 2017 and November 2019 at our hospital. ITMB was included as an analgesic component in the living donor strategy for early postoperative pain relief from November 2018 to November 2019 (n = 116). Kidney function was quantified based on the estimated glomerular filtration rate (eGFR), and delayed functional recovery of remnant kidney was defined as eGFR < 60 mL/min/1.73 m2 on postoperative day (POD) 1 (n = 240). RESULTS: Multivariable analyses revealed that lower risk for development of eGFR < 60 mL/min/1.73 m2 on POD 1 was associated with ITMB, female sex, younger age, and higher amount of hourly fluid infusion (area under the receiver operating characteristic curve = 0.783; 95% confidence interval = 0.734-0.832; p < 0.001). Propensity score (PS)-matching analyses showed that prevalence rates of eGFR < 60 mL/min/1.73 m2 on PODs 1 and 7 were higher in the non-ITMB group than in the ITMB group. ITMB adjusted for PS was significantly associated with lower risk for development of eGFR < 60 mL/min/1.73 m2 on POD 1 in PS-matched living donors. No living donors exhibited severe remnant kidney dysfunction and/or required renal replacement therapy at POD 7. CONCLUSIONS: We found an association between the analgesic impact of ITMB and better functional recovery of remnant kidney in living kidney donors. In addition, we propose a stratification model that predicts delayed functional recovery of remnant kidney in living donors: male sex, older age, non-ITMB, and lower hourly fluid infusion rate.

Intraoperative changes in whole-blood viscosity in patients undergoing robot-assisted laparoscopic prostatectomy in the steep Trendelenburg position with pneumoperitoneum: a prospective nonrandomized observational cohort study.

BACKGROUND: The aim of this study was to investigate the effect of the steep Trendelenburg position (STP) with pneumoperitoneum on whole-blood viscosity (WBV) in patients undergoing robot-assisted laparoscopic prostatectomy (RALP). The study also analyzed the associations of clinical patient-specific and time-dependent variables with WBV and recorded postoperative outcomes. METHODS: Fifty-eight adult male patients (ASA physical status of I or II) undergoing elective RALP were prospectively analyzed in this study. WBV was intraoperatively measured three times: at the beginning of surgery in the supine position without pneumoperitoneum; after 30 min in the STP with pneumoperitoneum; and at the end of surgery in the supine position without pneumoperitoneum. The WBV at a high shear rate (300 s- 1) was recorded as systolic blood viscosity (SBV) and that at a low shear rate (5 s- 1) was recorded as diastolic blood viscosity (DBV). Systolic blood hyperviscosity was defined as > 13.0 cP at 300 s- 1 and diastolic blood hyperviscosity was defined as > 4.1 cP at 5 s- 1. RESULTS: The WBV and incidences of systolic and diastolic blood hyperviscosity significantly increased from the supine position without pneumoperitoneum to the STP with pneumoperitoneum. When RALP was performed in the STP with pneumoperitoneum, 12 patients (27.3%) who had normal SBV at the beginning of surgery and 11 patients (26.8%) who had normal DBV at the beginning of surgery developed new systolic and diastolic blood hyperviscosity, respectively. The degree of increase in WBV after positioning with the STP and pneumoperitoneum was higher in the patients with hyperviscosity than in those without hyperviscosity at the beginning of surgery. Higher preoperative body mass index (BMI) and hematocrit level were associated with the development of both systolic and diastolic blood hyperviscosity in the STP with pneumoperitoneum. All patients were postoperatively discharged without fatal complications. CONCLUSIONS: Changes in surgical position may influence WBV, and higher preoperative BMI and hematocrit level are independent factors associated with the risk of hyperviscosity during RALP in the STP with pneumoperitoneum. TRIAL REGISTRATION: Clinical Research Information Service, Republic of Korea, approval number: KCT0003295 on October 25, 2018.

Heart-lung transplantation for refractory diffuse alveolar hemorrhage supported by prolonged extracorporeal membrane oxygenation after cardiogenic shock from ST segment elevation myocardial infarction: a case report.

Diffuse alveolar hemorrhage after percutaneous coronary intervention is a rare but fatal complication. Although timely application of extracorporeal membrane oxygenator and discontinuation of antiplatelet/anticoagulation is the treatment of choice, bleeding is often irreversible. Herein, we introduce a patient with refractory diffuse alveolar hemorrhage after prolonged extracorporeal membrane oxygenator and percutaneous coronary intervention, who was eventually rescued with heart-lung transplantation.

Value of Coronary Angiography in the Cardiac Myxoma.

Preoperative coronary angiography for cardiac myxoma not only excludes coronary artery disease but also detects the artery feeding the cardiac myxoma, which has several clinical implications. In this study, we examined cardiac myxoma cases in two tertiary hospitals using coronary angiography to identify the artery feeding the myxoma. We retrospectively reviewed 42 patients with cardiac myxoma who had undergone surgical removal between July 2008 and December 2015 in two tertiary hospitals, and recorded their baseline characteristics, echocardiographic findings, and coronary angiography. Among those 42 patients, 23 (55%) had coronary angiography before surgery and in no case was significant luminal narrowing observed. In 21 of the coronary angiograms, the artery feeding the cardiac myxoma had a vascular branch (100%), clusters of tortuous vessels with contrast medium pooling (67%), an arteriocavity fistula (33%), and a mobile feeding artery (67%). No significant relationship was found between coronary artery dominance type and the origin of the artery feeding the cardiac myxoma (P = 0.362). Identification of the artery feeding the cardiac myxoma, with a distinctive vascular appearance in coronary angiography, is important for several clinical applications such as helping to diagnose cardiac myxoma and to plan the surgical approach.

Factors associated with physical activity of breast cancer patients participating in exercise intervention.

PURPOSE: Physical activity has been known to improve survival and quality of life of patients with breast cancer. To find factors associated with physical activity, we analyzed the dataset of the multicenter controlled trial of exercise intervention. METHODS: Three hundred fifty-six participants were assigned to two groups: "Smart After-Care" (smartphone application and pedometer were provided) or exercise education only. Physical activity was measured by International Physical Activity Questionnaire-Short Form (IPAQ-SF) at baseline and after 12 weeks. The association between physical activity and other clinical characteristics was analyzed. RESULTS: At baseline, physical activity amount was 2315.5 ± 3513.2 MET min/week: 33.0% inactive, 49.6% minimally active, and 17.4% health-enhancing physical activity (HEPA) active. Factors associated with HEPA include cancer stage and grip strength. A significantly lower proportion was HEPA active among those with advanced stage than among those with stage 0. After intervention, physical activity was increased to 3466.2 ± 4712.5 MET min/week: 15.3% inactive, 50.4% minimally active, and 34.2% HEPA active. Physical activity was increased in 63.4% of the participants. Factors associated with physical activity increase include cancer stage, diarrhea, and type of exercise intervention. Participants with advanced stage have a 3.3 times higher chance of increasing physical activity. Participants who received "Smart After-Care" have a 64% higher chance of increasing physical activity. CONCLUSION: Before the intervention, participants with advanced stage are less likely to be HEPA active. Exercise intervention was more beneficial for those with advanced stage or physical symptoms. "Smart After-Care" was more effective than education only in increasing physical activity.

Smartphone Application Versus Pedometer to Promote Physical Activity in Prostate Cancer Patients.

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.

A randomized, prospective study of laparoendoscopic single-site plus one-port versus mini laparoscopic technique for live donor nephrectomy.

PURPOSE: To compare the clinical outcomes of laparoendoscopic single-site plus one-port donor nephrectomy (LESSOP-DN) and mini laparoscopic donor nephrectomy (MLDN). METHODS: A prospective randomized controlled trial was conducted from December 2014 to February 2016 in donors scheduled for left donor nephrectomy. Donor and recipient demographics and clinical outcomes including pain scores and questionnaires (BIQ: body image questionnaire, SF-36, patient-reported overall convalescence) were also compared. RESULTS: A total of 121 eligible donors were recruited, of which 99 donors who were scheduled to undergo an operation on their left side were randomized into LESSOP-DN (n = 50) and MLDN (n = 49) groups. There were no significant demographic differences between the two groups. The renal extraction time in the LESS-DN group was shorter than that in the MLDN group (75.89 ± 13.01 vs. 87.31 ± 11.38 min, p < 0.001). Other perioperative parameters and complication rates were comparable between the two groups. The LESSOP-DN group had a smaller incision length than the MLDN group (4.89 ± 0.68 vs. 6.21 ± 1.11 cm, p < 0.001), but cosmetic scores and body image scores were similar in the two groups (p = 0.905, 0.217). Donor quality of life (SF-36) and recovery and satisfaction data were comparable between the two groups. Delayed graft function (DGF) occurred in one recipient undergoing MLDN procedure (2.1%) and progressed to graft failure. CONCLUSIONS: There were no differences in cosmetic satisfaction between groups despite the smaller incision size of LESSOP-DN. Safety parameters and subjective measures of postoperative morbidity were similar between the two groups.

Reverse Left Ventricular Remodelling in ST-Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention: Incidence, Predictors, and Impact on Outcome.

BACKGROUD: We investigated reverse left ventricular remodelling (r-LVR), defined as a reduction of >10% in left ventricular end-systolic volume (LVESV) during follow-up, in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI). METHODS: STEMI patients (n=1,237) undergoing PPCI with echocardiography at baseline and 6-month follow-up were classified into r-LVR (n=466) and no r-LVR groups (n=771). The primary outcome was composite major adverse cardiac events (MACE; all-cause death, myocardial infarction, any revascularisation). RESULTS: r-LVR occurred in 466 patients (37.7%) and was associated with maximum troponin, door-to-balloon time, direct arrival to PPCI-capable hospital, coronary disease extent, initial left ventricular ejection fraction (LVEF), and LVESV. After propensity score (PS)-matching, initial LVEF and LVESV remained significant. During a median 403-day follow-up, 2-year MACE occurred in 166 patients (13.4%); its frequency was similar between groups (entire cohort: 13.5% vs. 13.4%, p=0.247; PS-matched: 11.8% vs. 11.8%, p=0.987). Kaplan-Meier estimates showed that MACE-free survival was comparable between groups (entire cohort: 86.5% vs. 86.6%, log rank p=0.939; PS-matched: 88.2% vs. 88.2%, log rank p=0.867). In Cox proportional hazard analysis, r-LVR was not associated with MACE (entire cohort: hazard ratio [HR] 1.018, 95% confidential interval [CI] 0.675-1.534, p=0.934; PS-matched: HR 1.001, 95% CI 0.578-1.731, p=0.999). CONCLUSION: We identified independent predictors of r-LVR and showed that while r-LVR occurred in 38% of our patients, it was not associated with clinical outcomes.
