To investigate the effect of the percentage of free prostate-specific antigen (%fPSA) on future prostate cancer risk.', 'We examined serum total PSA (tPSA) and %fPSA annually in a prostate cancer-screening cohort between July 2001 and June 2011. Men with tPSA >4.0 ng/mL or tPSA of 2.0-4.0 ng/mL with %fPSA 12% were screened as positive and were recommended to undergo a biopsy. The study population consisted of 6368 men, aged 40-79 years, who had tPSA 4.0 ng/mL at initial screening and who subsequently underwent 1 or more screenings. We calculated the cumulative risk and hazard ratio of prostate cancer stratified by the initial %fPSA groups as quartiles of prostate cancer patients.', 'During a median follow-up of 36 months, 119 men were diagnosed with prostate cancer. The lowest quartile of %fPSA (<13.3%) was associated with a 21.2-fold higher risk of having prostate cancer compared with the highest quartile (>22.2%). For the subset with an initial tPSA 1.0 ng/mL, all men diagnosed with cancer had an initial %fPSA 33.3% (median). For the subset with tPSA >1.0 ng/mL, men with %fPSA 23.0% (median) had significantly higher risk for cancer than those with %fPSA >23.0% (P <.0001). Of the 114 men with prostate cancer in whom pathologic findings were available, 79 (69.3%) had a Gleason score 3 + 4 = 7.

Little is known about endothelial function in adolescents with type 1 diabetes, and we evaluated endothelial dysfunction, using reactive hyperaemia peripheral arterial tonometry (RH-PAT).', 'This prospective, observational, 1-year study focused on 73 adolescents with type 1 diabetes, using multiple daily injections or continuous subcutaneous insulin infusion. The subjects were assessed using RH-PAT, body mass index, blood pressure, fasting lipid profile, glycated haemoglobin, insulin requirements and hours of physical exercise per week.', 'Endothelial dysfunction was observed in 56 patients (76.7%), with lower mean RH-PAT scores (1.260.22 versus 2.240.48, p<0.0001) and higher glycated haemoglobin values at baseline (8.271.24% versus 7.370.54%, p=0.006) and as a mean of the whole period since diagnosis (8.251.22% versus 7.720.82%, p=0.034). A higher percentage of patients with endothelial dysfunction showed abnormal cardiac autonomic tests (p=0.02) and were more sedentary, exercising <4 hours a week, than patients with normal endothelial function. After follow-up in 64/73 patients, we observed endothelial dysfunction in 81.8% of patients, despite a modest improvement in glycated haemoglobin.

Ex Input:
The appetite-stimulating properties of cannabis are well documented and have been predominantly attributed to the hyperphagic activity of the psychoactive phytocannabinoid, (9)-tetrahydrocannabinol ((9)-THC). However, we have previously shown that a cannabis extract devoid of (9)-THC still stimulates appetite, indicating that other phytocannabinoids also elicit hyperphagia. One possible candidate is the non-psychoactive phytocannabinoid cannabigerol (CBG), which has affinity for several molecular targets with known involvement in the regulation of feeding behaviour.', 'The objective of the study was to assess the effects of CBG on food intake and feeding pattern microstructure.', 'Male Lister hooded rats were administered CBG (30-120mg/kg, per ora (p.o.)) or placebo and assessed in open field, static beam and grip strength tests to determine a neuromotor tolerability profile for this cannabinoid. Subsequently, CBG (at 30-240mg/kg, p.o.) or placebo was administered to a further group of pre-satiated rats, and hourly intake and meal pattern data were recorded over 2h.', 'CBG produced no adverse effects on any parameter in the neuromotor tolerability test battery. In the feeding assay, 120-240mg/kg CBG more than doubled total food intake and increased the number of meals consumed, and at 240mg/kg reduced latency to feed. However, the sizes or durations of individual meals were not significantly increased.
