Abstract
BACKGROUND A fixed-dose combination (FDC) tablet formulation of amlodipine/losartan/rosuvastatin 5/100/20 mg was developed to improve medication compliance in patients with both hypertension and dyslipidemia. The comparative pharmacokinetic study was performed to compare the profile of an FDC tablet formulation of amlodipine/losartan/rosuvastatin with that of concomitant administration of a currently marketed FDC tablet of amlodipine/losartan with a rosuvastatin tablet. SUBJECTS AND METHODS A randomized, open-label, single oral dose, two-way crossover study was conducted in 60 healthy subjects. Subjects were orally administered the FDC tablet of amlodipine/losartan/rosuvastatin and a loose combination (LC) of two tablets comprising an FDC of amlodipine/losartan and rosuvastatin. Blood samples were collected for up to 144 h post dose for pharmacokinetic evaluations. Plasma concentrations of amlodipine, losartan, EXP3174 (an active metabolite of losartan), and rosuvastatin were measured by using liquid chromatography-tandem mass spectrometry. The geometric mean ratio (GMR) and its 90% confidence interval (90% CI) in the FDC treatment to LC treatment for the area under the concentration-time curve from zero to the last quantifiable time point (AUClast) and the maximum plasma concentration (Cmax) were calculated. Safety was monitored throughout the study. RESULTS The GMR (90% CI) values of AUClast and Cmax were 0.9946 (0.9663-1.0238) and 0.9690 (0.9379-1.0011) for amlodipine, 0.9855 (0.9422-1.0308) and 0.9178 (0.8349-1.0089) for losartan, 0.9814 (0.9501-1.0136) and 0.9756 (0.9313-1.0219) for EXP3174, and 0.9448 (0.8995-0.9923) and 0.9609 (0.8799-1.0494) for rosuvastatin, respectively. No clinically significant changes were observed in any of the safety parameters, including clinical laboratory tests, vital signs, electrocardiograms, and physical examinations, between the FDC treatment and the LC treatment. CONCLUSION We confirmed the pharmacokinetic equivalence of the FDC and LC treatments. This triple combination FDC formulation could be a clinically useful replacement for LC therapy.

Abstract
Higher motivation could support to lead behavioral change for obese children and adolescents. This study aimed to evaluate the effects of a nutrition care process (NCP)-based intervention targeted on diet and weight status in moderate to severe obese children and adolescents in Korea. One hundred four subjects (mean age: 10.95 years, body mass index (BMI) ≥97th percentile of age-sex) participated in the present study. Subjects were divided into a usual care group (UG) and a nutrition group (NG). All participants underwent nutrition education 6 times. The NG received individual access and continuous monitoring and setting goals with respect to nutritional problems. Consumption of high-calorie, low-nutrient (HCLN) food was significantly decreased (P < .05) and the Diet Quality Index-International (DQI-I) score also increased with respect to sodium (P < .001). The total self-efficacy score was increased from 9.15 to 10.14 points (P < .01). After 24 weeks, the BMI-z-score decreased from 2.27 to 2.19 in the NG (P < .05); however, no group difference was found. BMI-z-score was negatively associated with self-efficacy (β = -0.03, P < .019). NCP-based intervention might be helpful to solve dietary problems by enhancing self-efficacy and lower BMI-z-score in moderately to severely obese children and adolescents.

Plain language summary
Children and adolescents with obesity are at a high risk of being obese in adulthood. The aim of this study was to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity. The study is based on the Intervention for Childhood and Adolescents Obesity via Activity and Nutrition (ICAAN) – quasi-experimental intervention trial - which recruited 103 participants aged between 6 and sixteen years (63 were boys and 40 girls). The study was based on 2 active treatment groups (usual care group vs exercise group) receiving a 16-week intervention program. Results indicate that children and adolescents with obesity can achieve positive effects on body composition, physical fitness, and cardiometabolic markers, particularly with the exercise intervention. Authors conclude that the moderate-intensity multidisciplinary lifestyle intervention program they developed, can be sustained in the real-world setting and it is applicable to both moderate and severe obesity.
Abstract
This study aimed to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity, and assess the additional effects of exercise intervention when compared to usual care. Overall, the 103 enrolled participants were ≥85th percentile of age and sex-specific body mass index (BMI). Participants were divided into groups that received 16 weeks of either usual care or exercise intervention. The BMI z-score of the overall completers decreased by about 0.05 after the 16-week intervention (p = 0.02). After the intervention, only the exercise group had a significantly lower BMI z-score than the baseline score by about 0.1 (p = 0.03), but no significant group by time interaction effects were observed. At the 16-week follow-up, significant group by time interaction effects were observed in percentage body fat (%BF) (β = -1.52, 95%CI = -2.58⁻-0.45), lean body mass (LM) (β = 1.20, 95%CI = 0.12⁻2.29), diastolic blood pressure (β = -5.24, 95%CI = -9.66⁻-0.83), high-sensitivity C-reactive protein (β = -1.67, 95%CI = -2.77⁻-1.01), and wall sit test score (β = 50.74, 95%CI = 32.30⁻69.18). We developed a moderate-intensity intervention program that can be sustained in the real-world setting and is practically applicable to both moderate and severe obesity. After interventions, the exercise group had lower %BF and cardiometabolic risk markers, and higher LM and leg muscle strength compared to the usual care group.

Abstract
PURPOSE To compare compliance, toxicity, and outcome of weekly and triweekly cisplatin administration concurrent with radiotherapy in locally advanced cervical cancer. METHODS AND MATERIALS In this open-label, randomized trial, 104 patients with histologically proven Stage IIB-IVA cervical cancer were randomly assigned by a computer-generated procedure to weekly (weekly cisplatin 40 mg/m(2), six cycles) and triweekly (cisplatin 75 mg/m(2) every 3 weeks, three cycles) chemotherapy arms during concurrent radiotherapy. The difference of compliance and the toxicity profiles between the two arms were investigated, and the overall survival rate was analyzed after 5 years. RESULTS All patients tolerated both treatments very well, with a high completion rate of scheduled chemotherapy cycles. There was no statistically significant difference in compliance between the two arms (86.3% in the weekly arm, 92.5% in the triweekly arm, p > 0.05). Grade 3-4 neutropenia was more frequent in the weekly arm (39.2%) than in the triweekly arm (22.6%) (p = 0.03). The overall 5-year survival rate was significantly higher in the triweekly arm (88.7%) than in the weekly arm (66.5%) (hazard ratio 0.375; 95% confidence interval 0.154-0.914; p = 0.03). CONCLUSIONS Triweekly cisplatin 75-mg/m(2) chemotherapy concurrent with radiotherapy is more effective and feasible than the conventional weekly cisplatin 40-mg/m(2) regimen and may be a strong candidate for the optimal cisplatin dose and dosing schedule in the treatment of locally advanced cervical cancer.

Abstract
BACKGROUND In the treatment of urothelial cancer, identification of patients who are likely to benefit from further therapy after cisplatin failure is crucial for reasonable treatment decisions. OBJECTIVE Validate the prognostic factor model (PFM) for survival developed by Bellmunt et al. in a different patient cohort with a different chemotherapy regimen. DESIGN, SETTING, AND PARTICIPANTS Baseline parameters of 102 patients treated within a randomized phase 3 trial of second-line gemcitabine and paclitaxel (GP) comparing short-term to prolonged chemotherapy (German Association of Urological Oncology trial AB20/99) were analyzed. Patients were stratified according to the PFM based on a score including performance status, presence of hepatic metastases, and hemoglobin levels. MEASUREMENTS The baseline parameters of the GP cohort were compared with those of patients treated in the phase 3 trial of vinflunine versus best supportive care. Univariate and multivariate analyses of baseline parameters with respect to overall survival (OS) and treatment response were performed. OS of patients stratified according to the PFM was compared by log-rank test. RESULTS AND LIMITATIONS The vinflunine and the GP cohorts differed, as patients after perioperative (neoadjuvant or adjuvant) treatment were included in the latter cohort. According to the PFM, prognostic subgroups with significant difference in OS (11.8 mo [95% confidence interval (CI), 6.3-17.3], 8.1 mo [95% CI, 4.8-11.4], 3.2 mo [95% CI, 0.0-7.9]; p=0.007) were identified. The PFM identified risk groups in patients with failed treatment of metastatic disease (14.1 mo [95% CI, 8.9-19.3], 7.3 mo [95% CI, 0.0-17.8], 3.8 mo [95% CI, 0.0-9.0]; p=0.006) but not in patients treated (neo)adjuvantly. Lymph node-only disease was a strong predictor of treatment response that overruled every other single predictive parameter (0.284, p=0.0266). CONCLUSIONS The PFM was successfully validated in the GP and should be used to tailor second-line treatment strategy. Patients with lymph node-only disease may benefit from second-line treatment even if anemia or impaired performance status is present.

Abstract
The delayed release of mycophenolic acid (MPA) from enteric-coated mycophenolate sodium (EC-MPS, myfortic®) may have an impact on the variability of MPA trough (C0 h) levels. A randomized, two-period crossover study was performed in 24 maintenance renal transplants to evaluate the inter- and intrasubject variability of MPA predose levels from EC-MPS and mycophenolate mofetil (MMF, CellCept®), both in combination with cyclosporine. Patients received EC-MPS (720 mg b.i.d.) and MMF (1000 mg b.i.d.) for a period of 21 d each. MPA plasma levels were measured over the final seven consecutive days at -1, 0, 1, 2, and 3 h after the morning MPA dose. Intersubject coefficients of variation (%CV) for MPA troughs were 47.5% (95% CI, 34.1-80.3) and 54.4% (40.0-86.8) for EC-MPS and MMF, respectively; intrasubject %CVs were 62.7% (55.1-72.9) and 42.8% (37.9-49.2). High MPA C0 h levels>10 μg/mL were rarely observed with both EC-MPS (1.8%) and MMF (0.6%). Mean MPA area under the curve (AUC)0-3 h was comparable between treatments, while MPA C0 h was on average 46% higher with EC-MPS. In conclusion, predose MPA trough level monitoring appears of limited value during EC-MPS and MMF therapy given the large intrasubject variability in MPA C0 h levels with both treatments.

Abstract
UNLABELLED Mycophenolate mofetil (MMF) and sirolimus (SRL) are effective immunosuppressive drugs with distinct safety profile. METHODS Kidney transplant recipients receiving tacrolimus (TAC)-based immunosuppressive regimen were randomized to receive fixed daily doses of MMF (2 g/d, n = 50) or SRL (one loading dose of 15 mg, 5 mg/d till day 7 and 2 mg/d thereafter, n = 50) without induction therapy. RESULTS No differences were observed in the incidence of the composite (biopsy-confirmed acute rejection, graft loss or death) end-point (18% vs. 16%, p = 1.000), biopsy confirmed acute rejection (12% vs. 14%, p = 1.000), one-yr patient (94% vs. 98%, p = 0.308), graft (92% vs. 98%, p = 0.168), and death-censored graft survival (98% vs. 100%, p = 0.317) comparing patients receiving MMF or SRL respectively. Patients receiving SRL showed worse safety outcomes, higher mean creatinine (1.6 +/- 0.5 mg/dL vs. 1.4 +/- 0.3 mg/dL, p = 0.007), higher proportion of patients with proteinuria (52.0% vs. 10.7%, p = 0.041), higher mean urinary protein concentrations (0.3 +/- 0.5 g/L vs. 0.1 +/- 0.2 g/L, p = 0.012), higher mean cholesterol concentration (217 mg/dL vs. 190 mg/dL, p = 0.030), and higher proportion of patients prematurely discontinued from randomized therapy (26% vs. 8%, p = 0.031). CONCLUSION In patients receiving TAC, MMF produced similar efficacy but superior safety profile compared with SRL.
