Purpose: This 2-year follow-up study aimed to examine the associations between total volume, frequency, duration, and speed of walking with subsequent sleep difficulty in older ***: A total of 800 older adults aged 65 years and over participated in the first survey in 2012 and 511 of them were followed 2 years *** 5-item Athens Insomnia Scale(AIS-5) was used to measure sleep difficulty. Frequency, duration, and speed of outdoor walking were self-reported. Walking speed was assigned a metabolic equivalent value(MET) from 2.5 to 4.5. Total walking volume in MET-h/week was calculated as frequency × duration × speed. Negative binomial regressions were performed to examine the associations between volume and components of walking with subsequent sleep difficulty with covariates of age, sex, education, marital status, living arrangement, smoking, alcohol consumption, mental health, Charlson Index, exercise(excluding walking), and sleep difficulty at ***: Participants with low walking volume had a higher level of sleep difficulty 2 years later compared with those with high walking volume(incident rate ratios = 1.61, p = 0.004). When speed, frequency, and duration of walking were simultaneously entered into 1 model, only walking speed was significantly associated with subsequent sleep difficulty(after the model was adjusted for covariates and baseline sleep difficulty).Sensitivity analyses showed that walking duration emerged as a significant predictor among 3 walking parameters, with 2-year changes of sleep scores as dependent ***: Total amount of walking(especially faster walking and lasting for more than 20 min) is associated with less subsequent sleep difficulty after 2 years among older adults.

Objective: To investigate the effect of hydrogen-rich Korean Red Ginseng(KRG) water(HRGW) mixture on the spermatogenesis and sperm motility of mice of different ages. Methods: Eighty young(3 month-old) and aged(12 month-old) male mice were randomly assigned to 4 groups(n=10 per group) including control group, hydrogen-rich water(HRW) group(10 m L/kg daily), KRG group(50 mg/kg daily) and HRGW group(10 m L/kg HRW and 50 mg/kg KRG daily) by an oral zoned needle for 4 weeks. Sperm count and motility were measured using sperm suspension released from cauda epididymis. Serum follicle stimulating hormone(FSH), luteinizing hormone(LH), testosterone, and reactive oxygen species(ROS) in serum have also been estimated. Tubular changes were examined through histological hematoxylin and eosin staining. Expression of antioxidation(PPx3, PPx4, GSTm5 and GPx4), spermatogenesis(inhibin-α, neptin-2 and CREM), antiaging(SIRT1 and SIRT2), and angiogenesis [visfatin and vascular endothelial growth factor(VEGF)] related genes were examined through realtime polymerase chain reaction. Results: HRW and KRG treatment stimulated spermatogenesis followed by increasing sperm production and sperm motility(P<0.05). These effects were strengthened synergistically by a HRGW mixture(P<0.05 or P<0.01). HRGW greatly increased the expressions of antioxidation, antiaging, spermatogenesis related genes and VEGF especially in aged mice(P<0.05). Serum testosterone and FSH levels also increased, while serum ROS level decreased(all P<0.05). Conclusion: HRGW increases sperm production and motility by enhancing antioxidation and stimulating spermatogenesis and sex hormone production, particularly in aged mice.

Patients diagnosed with AP were randomly and equally assigned to EA1, EA2 or control groups. All participants received conventional standard-of-care therapy for AP. Local EA alone was administered in EA1, and local plus distal EA was given in *** EA included two abdominal acupoints, while distal EA included twelve peripheral acupoints. EA groups underwent one session of EA daily for 4 days(days 1–4), or until pain was resolved or *** outcome measures: The primary outcome measure was the change in the visual analogue scale(VAS;0–100) pain score between baseline and day ***: Eighty-nine participants were randomized into EA1, EA2 and control groups, and 88(EA1, 30;EA2, 29;control, 29) were included in the full-analysis set. VAS score change(median [interquartile range]) on day 5 was(12.3 ± 22.5) in the EA1 group,(10.3 ± 21.5) in the EA2 group, and(8.9 ± 15.2) in the control group. There were not significant differences in the change in VAS score among treatments(P = 0.983). However, time to food intake was significantly shorter in the EA group(EA1 + EA2) than in the control group(median 2.0 days vs 3.0 days), with a hazard ratio of 0.581(P = 0.022;95% CI,0.366–0.924). No significant adverse events ***: EA treatment did not significantly reduce pain after 4 days of treatment in patients with AP-associated abdominal pain but significantly reduced time to first food intake.

AIM To investigate Helicobacter pylori (H. pylori) eradication rates using second-line bismuth-containing quadruple therapy and to identify predictors of eradication *** This study included 636 patients who failed firstline triple therapy and received 7d of bismuthcontaining quadruple therapy between January 2005 and December 2015. We retrospectively demonstrated H. pylori eradication rates with respect to the year of therapy as well as demographic and clinical factors. H. pylori eradication was confirmed by a 13C-urea breath test or a rapid urease test at least 4 wk after the completion of bismuth-based quadruple therapy: proton pump inhibitor, metronidazole, bismuth, and *** The overall eradication rates by intention-to-treat analysis and per-protocol analysis were 73.9%( 95% CI : 70.1 %- 77.4%) and 94.5% (95% CI : 92.4%-96.5%), respectively. Annual eradication rates from 2005 to 2015 were 100.0%, 92.9%, 100.0%, 100.0%, 100.0%, 97.4%, 100.0%, 93.8%, 84.4%, 98.9%, and 92.5%, respectively, by per-protocol analysis. A multivariate analysis showed that diabetes mellitus (OR=3.99, 95%CI: 1.56-10.20, P=0.004)was associated with H. pylori eradication therapy *** The second-line bismuth-containing quadruple therapy for H. pylori infection is still effective in Korea, and diabetes mellitus is suggested to be a risk factor for eradication failure.

Prostate-specific antigen density predicts favorable pathology and biochemical recurrence in patients with intermediate-risk prostate cancer

Asian Journal of Andrology 2016年第3期18卷 480-484,I0012页

作者： Ho Won Kang hae Do jung Joo Yong Lee Jong Kyou Kwon Seong Uk Jeh Kang Su Cho Won Sik Ham Young Deuk Choi Department of Urology Chungbuk National University College of Medicine Cheongju Korea Department of Urology Severance Hospital Urological Science InstituteYonsei University College of Medicine Seoul Korea Department of Urology.

This study was designed to identify clinical predictors of favorable pathology and biochemical recurrence （BCR） in patients with intermediate-risk prostate cancer （IRPCa）. Between 2006 and 2012, clinicopathological and oncological data from 203 consecutive men undergoing robot-assisted radical prostatectomy （RARP） for IRPCa were reviewed in a single-institutional retrospective study. Favorable pathology was defined as Gleason score 〈6 and organ-confined cancer as detected by surgical pathology. Logistic regression analysis was used to determine predictive variables of favorable pathology, and the Kaplan-Meier and multivariate Cox regression model were used to estimate BCR-free survival after RARP. Overall, 38 patients （18.7%） had favorable pathology after RARP. Lower quartile prostate-specific antigen density （PSAD） was associated with favorable pathology compared to the highest quartile PSAD after adjusting for preoperative PSA, clinical stage and biopsy Gleason score （odds ratio, 5.42; 95% confidence interval, 1.01-28.97; P = 0.048）. During a median 37.8 （interquartile range, 24.6-60.2） months of follow-up, 66 patients experienced BCR. There were significant differences with regard to BCR free survival by PSAD quartiles （log rank, P = 0.003）. Using a multivariable Cox proportion hazard model, PSAD was found to be an independent predictor of BCR in patients with IRPCa after RARP （hazard ratio, 4.641; 95% confidence interval, 1.109-19.417; P = 0.036）. The incorporation of the PSAD into risk assessments might provide additional prognostic information and identify some patients in whom active surveillance would be appropriate in patients with IRPCa.
