The goal of the study is to locate a site appropriate for a 170 offender unit, based on an understanding of current needs, existing and proposed procedure and the longevity of existing facility use. The study is based on master-plan process. A framework on which multiple stages of infrastructure development can be based is initiated through the systemic study of infrastructure condition, infrastructure needs and treatment objectives.

Seasonal changes in 24-h and basal energy expenditures in rural Gambian men as measured in a respiration chamber.

Adaptation of 24-h energy expenditure (24-h EE) to seasonal variations in food availability was studied, by using a respiration chamber, in 18 rural Gambian men on three occasions: period 1--at the end of the rainy season, which is characterized by low food availability; period 2--during the nutritionally favorable dry season; and period 3--at the onset of the following rainy season. From periods 1 to 2 body weight increased by 2.8 +/- 0.4 kg, and a rise in 24-h EE was observed (from 8556 +/- 212 kJ/d to 9166 +/- 224 kJ/d), which was correlated to weight change (r = 0.73, P less than 0.001). During period 3, 24-h EE averaged 8740 +/- 194 kJ/d. Diet-induced thermogenesis increased significantly from periods 1 to 2 (5.9 +/- 0.5% to 8.2 +/- 0.8%) and subsequently decreased to 3.6 +/- 0.6% during period 3. In rural Gambian men, metabolic adaptations in response to seasonal changes in food availability are reflected by a decrease in body weight, mainly manifested by a loss of fat-free mass accompanied by a decreased 24-h EE and a lowered diet-induced thermogenesis.

The work of Spanish men. A quantitative analysis based on census data, 1900-1970

This paper presents a historical examination of employment in old age in Spain, in order to characterize this labour segment and identify and analyse its specific problems. One of these problems is the life-cycle deskilling process, already shown for certain national cases. This study explores whether this hypothesis also holds in Spain. The perspective used is essentially quantitative, as our analysis is based on the age-profession tables in Spanish population censuses from 1900 to 1970.

Training in hypoxia fails to further enhance endurance performance and lactate clearance in well-trained men and impairs glucose metabolism during prolonged exercise.

The aim of this study was to investigate the synergistic effects of endurance training and hypoxia on endurance performance in normoxic and hypoxic conditions (approximately 3000 m above sea level) as well as on lactate and glucose metabolism during prolonged exercise. For this purpose, 14 well-trained cyclists performed 12 training sessions in conditions of normobaric hypoxia (HYP group, n = 7) or normoxia (NOR group, n = 7) over 4 weeks. Before and after training, lactate and glucose turnover rates were measured by infusion of exogenous lactate and stable isotope tracers. Endurance performance was assessed during incremental tests performed in normoxia and hypoxia and a 40 km time trial performed in normoxia. After training, performance was similarly and significantly improved in the NOR and HYP groups (training, P < 0.001) in normoxic conditions. No further effect of hypoxic training was found on markers of endurance performance in hypoxia (training x hypoxia interaction, n.s.). In addition, training and hypoxia had no significant effect on lactate turnover rate. In contrast, there was a significant interaction of training and hypoxia (P < 0.05) on glucose metabolism, as follows: plasma insulin and glucose concentrations were significantly increased; glucose metabolic clearance rate was decreased; and the insulin to glucagon ratio was increased after training in the HYP group. In conclusion, our results show that, compared with training in normoxia, training in hypoxia has no further effect on endurance performance in both normoxic and hypoxic conditions or on lactate metabolic clearance rate. Additionally, these findings suggest that training in hypoxia impairs blood glucose regulation in endurance-trained subjects during exercise.

Stimulation of thermogenesis in men after combined glucose-long-chain triglyceride infusion.

The effect of combined long-chain triglyceride infusion (Intralipid 20%) with graded doses of insulin/glucose on energy expenditure was examined in 17 healthy young male volunteers by using the euglycemic insulin clamp technique in combination with indirect calorimetry. Intralipid was infused for 90 min at a constant rate of 0.23 g/min; plasma free fatty acids increased from base-line values of 380 +/- 8 mumol/l to steady state levels of 650 +/- 12 mumol/l. After 90 min the Intralipid was continued and insulin was infused at three rates (0.5, 2, and 4 mU/kg . min) to achieve steady state hyperinsulinemic plateaus of 63 +/- 4, 167 +/- 10, and 410 +/- 15 microU/ml. Plasma glucose concentration was maintained constant at basal euglycemic levels (insulin clamp technique) by infusing glucose at 0.24, 0.48, and 0.59 g/min, respectively. Glucose storage during the insulin clamp (ie, glucose uptake minus glucose oxidation) was 0.13, 0.33, and 0.40 g/min for each group and exogenous lipid storage was 0.17, 0.18, and 0.19 g/min, respectively. The net increment in energy expenditure was 0.15, 0.24, and 0.26 kcal/min, respectively, which represents 8.5% of the energy content of the total amount of glucose and lipid stored. The experimentally determined value (approximately 9%) for the cost of storing both glucose and lipid was found to be significantly greater than predicted by stoichiometric calculations. However, the experimental value for the combined infusion was less than that observed for glucose storage alone (12%). This finding provides support for the use of combined glucose/fat infusions in parenteral nutrition as it is used more economically than when glucose is infused alone.

Effectiveness of a brief integrative multiple substance use intervention among young men with and without booster sessions.

Brief interventions (BI) commonly employ screening and target a single substance. Multi-substance interventions are a more adequate reflection of risk behaviors in adolescents and young adults. Systematic screening complicates BI in many settings. The effectiveness of a voluntary multi-substance intervention among 19-year-old men and the incremental impact of booster sessions were analyzed. Participants were enrolled during mandatory army conscription in Switzerland. Compared with 461 controls, 392 BI subjects showed reduced substance use on 10 of 12 measures (4 tobacco, 4 cannabis, and 2 alcohol measures). Between-group effects were small and non-significant (except for cannabis use prevalence). Three-month booster sessions were not effective and even contraindicated. The usefulness of targeting multi-substances during BIs without prior screening depends on the value of small effects. The addition of booster sessions was not effective and therefore is not recommended.

Estradiol levels in men with congenital hypogonadotropic hypogonadism and the effects of different modalities of hormonal treatment.

Objective: To evaluate the degree of E-2 deficiency in male congenital hypogonadotropic hypogonadism (CHH), and its response to different hormonal treatments.Design: Retrospective and prospective studies.Setting: Academic institution.Patient(s): Untreated or treated CHH, healthy men, untreated men with Klinefelter syndrome (KS). Intervention(s): Serum sex hormone-binding globulin (SHBG) and total E-2 (TE2) as well as bioavailable (BE2) and free (FE2) levels were measured and determined.Main Outcome Measure(s): Total, bioavailable, and free testosterone, TE2, BE2, FE2 were compared in normal men, untreated and treated CHH and in untreated KS.Result(s): TE2, BE2, and FE2 levels were very significantly lower in untreated patients with CHH (n = 91) than in controls (n = 63) and in patients with KS (n = 45). The TE2 correlated positively with serum total T in patients with CHH. The TE2 also correlated very positively with serum LH in the combined population of patients with CHH and healthy men, suggesting that low E-2 levels in CHH are due to severe LH-driven T deficiency. All fractions of circulating E-2 were very significantly higher in patients with CHH receiving T enanthate (n = 101) or the FSH-hCG combination (n = 88) than in untreated patients with CHH. Contrary to dihydrotestosterone (DHT), both T enanthate and combined FSH-hCGtherapy significantly and prospectively increased TE2 levels in patients with CHH.Conclusion(s): Contrary to KS, the male hypogonadism observed in CHH is associated with profound E-2 deficiency, which can be overcome by aromatizable androgen or combined gonadotropin therapy.

Spatial relational learning and memory abilities do not differ between men and women in a real-world, open-field environment

This study assesses gender differences in spatial and non-spatial relational learning and memory in adult humans behaving freely in a real-world, open-field environment. In Experiment 1, we tested the use of proximal landmarks as conditional cues allowing subjects to predict the location of rewards hidden in one of two sets of three distinct locations. Subjects were tested in two different conditions: (1) when local visual cues marked the potentially-rewarded locations, and (2) when no local visual cues marked the potentially-rewarded locations. We found that only 17 of 20 adults (8 males, 9 females) used the proximal landmarks to predict the locations of the rewards. Although females exhibited higher exploratory behavior at the beginning of testing, males and females discriminated the potentially-rewarded locations similarly when local visual cues were present. Interestingly, when the spatial and local information conflicted in predicting the reward locations, males considered both spatial and local information, whereas females ignored the spatial information. However, in the absence of local visual cues females discriminated the potentially-rewarded locations as well as males. In Experiment 2, subjects (9 males, 9 females) were tested with three asymmetrically-arranged rewarded locations, which were marked by local cues on alternate trials. Again, females discriminated the rewarded locations as well as males in the presence or absence of local cues. In sum, although particular aspects of task performance might differ between genders, we found no evidence that women have poorer allocentric spatial relational learning and memory abilities than men in a real-world, open-field environment.
