MATERIALS AND METHODS: An online search was done for studies reporting incidental prostate cancer in cystoprostatectomy specimens. After following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines we identified a total of 34 reports containing 13,140 patients who underwent radical cystoprostatectomy for bladder cancer with no previous history of prostate cancer. A cumulative analysis was performed on the available data regarding prevalence, clinicopathological features and oncologic outcomes. RevMan, version 5.3 was used for data meta-analysis.
RESULTS: Of the 13,140 patients incidental prostate cancer was detected in 3,335 (24.4%). Incidental prostate cancer was significantly associated with greater age (Z = 3.81, p = 0.0001, d = 0.27, 95% CI -0.14-0.68), lymphovascular invasion of bladder cancer (Z = 2.07, p = 0.04, r = 0.14, 95% CI 0.09-0.18) and lower 5-year overall survival (Z = 2.2, p = 0.03). Among patients with clinically significant and insignificant prostate cancer those with clinically significant prostate cancer significantly more frequently showed a positive finding on digital rectal examination (Z = 3.12, p = 0.002, r = 0.10, 95% CI 0-0.19) and lower 5-year overall survival (Z = 2.49, p = 0.01) whereas no effect of age was observed (p = 0.15). Of 1,320 patients monitored for biochemical recurrence prostate specific antigen recurrence, defined as prostate specific antigen greater than 0.02 ng/ml, developed in 25 (1.9%) at between 3 and 102 months.
CONCLUSIONS: This meta-analysis suggests that incidental prostate cancer detected during histopathological examination of radical cystoprostatectomy specimens might be linked with adverse characteristics and outcomes in patients with invasive bladder cancer.
MATERIALS AND METHODS: The addressed focused question was "Is there a difference in the resistin levels between individuals with CP and those without CP?" four electronic databases: Medline, PubMed (National Institutes of Health, Bethesda), EMBASE, and Science direct databases from 1977 up to March 2016 for appropriate articles addressing the focused question. EMBASE and Medline were accessed using OVID interface which facilitated simultaneous search of text words, MeSH or Emtree. Unpublished studies (gray literature) were identified by searching the Open-GRAY database and references of the included studies (cross referencing) were performed to obtain new studies. In-vitro studies, animal studies, studies that reported levels of other cytokines but not resistin, letters to the editor and review papers were excluded.
RESULTS: Ten studies were included. Nine studies compared resistin levels between CP and periodontally healthy (H) individuals and reported higher mean serum and GCF levels of resistin in CP patients than the H controls. Two studies showed comparable resistin levels from GCF and serum between diabetes mellitus with CP (DMCP) and CP groups. Three studies included obese subjects and showed comparable serum and GCF resistin levels between obese subjects with CP (OBCP) and CP subjects.
CONCLUSIONS: CP patients were presented with elevated levels of GCF or serum resistin as compared with H individuals. Resistin modulates inflammation in chronic periodontal disease and may be used as surrogate measure to identify subjects at risk for periodontitis. Resistin levels in patients with CP and systemic inflammatory disorders such as diabetes, obesity, or rheumatoid arthritis was not significantly higher than the levels in patients with only CP.
DESIGN: Systematic review and meta-analysis.
SETTING: Primary care setting.
PARTICIPANTS: Of 1568 studies screened, 14 studies with 7035 PWID were included.
MEASURES: PubMed, Embase, Web of Sciences, CENTRAL and Cochrane review databases were searched without language restriction from their inception to 27 January 2016. All published study designs with control groups that reported the effectiveness of pharmacy-based NSP on outcomes of interest were included. Outcomes of interest are risk behaviour (RB), HIV/hepatitis C virus (HCV) prevalence and economic outcomes. The estimates of pooled effects of these outcomes were calculated as pooled odds ratio (OR) with 95% confidence interval (CI) using a random-effects model. Heterogeneity was assessed by I2 and χ2 tests.
FINDINGS: Most studies (nine of 14, 64.3%) were rated as having a serious risk of bias, while 28.6 and 7.1% were rated as having a moderate risk and low risk of bias, respectively. For sharing-syringe behaviour, pharmacy-based NSPs were significantly better than no NSPs for both main (OR = 0.50, 95% CI = 0.34-0.73; I2 = 59.6%) and sensitivity analyses, excluding studies with a serious risk of bias (OR = 0.52, 95% CI = 0.32-0.84; I2 = 41.4%). For safe syringe disposal and HIV/HCV prevalence, the evidence for pharmacy-based NSPs compared with other NSP or no NSP was unclear, as few of the studies reported this and most of them had a serious risk of bias. Compared with the total life-time cost of US$55 640 for treating a person with HIV infection, the HIV prevalence among PWID has to be at least 0.8% (for pharmacy-based NSPs) or 2.1% (for other NSPs) to result in cost-savings.
CONCLUSIONS: Pharmacy-based needle/syringe exchange programmes appear to be effective for reducing risk behaviours among people who inject drugs, although their effect on HIV/HCV prevalence and economic outcomes is unclear.
RESULTS: A combined process of microwave pretreatment and solvent extraction to mill crude palm oil, without introducing water or steam, is described. An excellent yield (up to 30%) of oil was obtained with pretreatment in a 42 L, 1000 W and 2450 MHz microwave oven followed by hexane extraction. The optimum conditions (10 min microwave pretreatment and 12 h solvent extraction) yielded an oil with a low free fatty acid content (<1.0%) and an acceptable anisidine value (<3.0 meq kg(-1) ). The oil had a fatty acid composition not resembling those of conventional crude palm oil and crude palm kernel oil. In the pretreatment, the leached oil had 6.3% lauric acid whereas the solvent extracted oil had only 1.5% lauric acid. Among the factors affecting the oil quality, microwave pretreatment affected the oil quality significantly; however, an optimised duration that would ensure high efficiency in solvent extraction also resulted in ruptured fruitlets, although not to the extent of causing excessive oxidation. In fact, microwave pretreatment should exceed 12 min; after only 15 min, the oil had 1-methylcyclopentanol (12.96%), 1-tetradecanol (9.44%), 1-nonadecene (7.22%), nonanal (7.13%) and 1-tridecene (5.09%), which probably arose from the degradation of fibres.
CONCLUSION: Microwave pretreatment represents an alternative milling process for crude palm oil compared with conventional processes in the omission of wet treatment with steam. © 2016 Society of Chemical Industry.
METHODS: Retrospective review of 48 patients (48 hips) with follow-up duration of average 11.4 years (range, 6.1-21.4 years) was conducted. At each follow-up, Harris hip score was used to assess functional outcome, and radiographic acetabular component osteolysis was measured by DeLee and Charnley classification. Bone defects were assessed preoperatively and intraoperatively using American academy of orthopedic surgeons and Paprosky classification. The common modes of ARRH failures were evaluated. Bone consolidation, presence of heterotopic ossification, and complications such as infection and dislocation were recorded.
RESULTS: The bone defects were varied and included cavitary, segmental, and combined defects without any pelvic discontinuity. Mean Harris hip score improved from 52.6 points preoperatively to 82.0 points postoperatively. Nine acetabular revisions and 3 stem revisions (2 concurrent with acetabular revisions and 1 isolated stem revision) were performed. There were 5 infected cases and 1 patient with recurrent dislocation. The 11.4-year survival of revision THA with ARRH was 71% as the end point for acetabular revision surgery for any reason. The expected 15-year survival of revision THA with ARRH was 60%. The most common failure mode of ARRH was superomedial migration followed by lateral migration.
CONCLUSION: ARRH combined with bone grafting produces relatively good average long-term clinical results.
METHODS: This prospective study was performed between 2011 and 2015. All 150 patients were given 10 mg daily isotretinoin until a cumulative dose of 90-110 mg/kg.
RESULTS: The mean age was 26.6 years with 64.7% moderate acne, 29.3% severe, and 6% very severe. The mean cumulative dose was 98.8 ± 6.05 mg/kg. All 150 patients had total clearance with a mean time to clearance of 24.0 weeks. Patients with severe/very severe acne had higher cumulative dosage (102.1 vs. 97.0, P
