Abstract
OBJECTIVE We investigated whether more advanced climacteric stage in the mid-40s is associated with thyroid autoimmunity and dysfunction. METHODS This cross-sectional cohort study included 2,569 46-year-old women. Thyroid hormone, thyroid peroxidase antibodies, and follicle-stimulating hormone levels were determined. Using menstrual history and follicle-stimulating hormone levels, the participants were divided into climacteric (n = 340) and preclimacteric (n = 2,229) groups. Women diagnosed with premature ovarian insufficiency (menopause by 40 y of age) were excluded. The use of thyroid medication was evaluated from the medication reimbursement register. The prevalence of thyroid medication use, laboratory-based thyroid dysfunction, and thyroid peroxidase antibody positivity was compared between the two groups. The association between climacteric status and thyroid disorders was investigated using a logistic regression model including smoking and thyroid antibody status. RESULTS At 46 years old, climacteric women used thyroid medication more often than preclimacteric women (9.1% vs 6.1%; P = 0.04). There was no difference in the prevalence of subclinical or clinical hypothyroidism and hyperthyroidism in nonmedicated participants (5.5% vs 5.0%; P = 0.7) or thyroid peroxidase antibody positivity (14.0% vs 15.0%, P = 0.7). In the regression model, being climacteric (OR = 1.6; 95% CI 1.1-2.3; P = 0.02) and antibody positivity (OR 4.9; 95% CI 3.6-6.6; P < 0.001) were associated with a higher prevalence of thyroid dysfunction. CONCLUSIONS More advanced climacteric stage in the mid-40s was slightly associated with thyroid dysfunction but not thyroid autoimmunity.

Abstract
OBJECTIVE To investigate vitamin D status in women with the onset of the climacteric phase by age 46 as both early menopause and inadequate vitamin D status may increase the risk of adverse health outcomes. METHODS A cross-sectional study included 2,544, 46-year-old women from a birth cohort. Women were divided into the following two groups according to their menstrual history and follicle-stimulating hormone (FSH) concentration: 1) climacteric (FSH ≥25 IU/L and amenorrhea ≥4 mo, n = 351) and 2) preclimacteric women (FSH <25 IU/L and having regular/irregular menstrual cycles, n = 2,193). Serum 25-hydroxyvitamin D (25(OH)D) concentrations were compared between the groups. A linear regression model was performed to investigate which factors are associated with 25(OH)D status. RESULTS Mean serum 25(OH)D concentrations were higher in climacteric compared with preclimacteric women (68.1 ± 19.8 nmol/L vs 65.2 ± 19.3 nmol/L, P = 0.01). However, in the linear regression model, climacteric status was not associated with 25(OH)D status (multivariable adjusted mean difference 4.5 nmol/L, 95% confidence interval -1.4 to 10.4, P = 0.137). A total of 76 of the climacteric women were using systemic estrogen hormone therapy (HT). In a subanalysis, including only climacteric women, the use of HT was associated with higher 25(OH)D status (multivariable adjusted mean difference 5.9 nmol/L, 95% confidence interval 1.3-10.5, P = 0.013). CONCLUSIONS The onset of the climacteric phase by age 46 was not associated with inadequate 25(OH)D concentrations, whereas HT use was associated with higher 25(OH)D status in women with early-onset climacterium.

Abstract
The raccoon dog (Nyctereutes procyonoides) is a promising animal model capable of preventing disuse-induced osteoporosis. Previous data suggest that this species resembles bears in the preservation of bone mass and biomechanical properties during prolonged passivity and catabolism. This longitudinal study examined the osteological properties of tibiae in farm-bred raccoon dogs that were either fed or fasted (n=6 per group) for a 10 week period. Peripheral quantitative computed tomography was utilized and plasma markers of bone turnover measured before fasting and at 9 weeks followed by mechanical testing (three-point bending), micro-computed tomography and Fourier transform infrared imaging at 10 weeks. Passive wintering with prolonged catabolism (body mass loss 32%) had no significant effects on bone mineralization, porosity or strength. The concentration of C-terminal telopeptide of type I collagen, indicative of bone resorption, increased in the plasma of the fasted raccoon dogs, while the bone formation markers were unchanged. The levels of 25-hydroxyvitamin D were reduced in the fasted animals. Based on these data, the preservation of bone in wintering raccoon dogs shares characteristics with that of bears with no apparent decrease in the formation of bone but increased resorption. To conclude, raccoon dogs were able to minimize bone loss during a 10 week period of catabolism and passivity.

Abstract
BACKGROUND Although both ethanol consumption and overweight alter the activities of hepatic enzymes in circulation, the differentiation of an alcohol or nonalcohol basis for such changes remains problematic. The magnitude of alterations occurring among moderate drinkers has remained obscure. OBJECTIVE We examined the links between moderate ethanol consumption, body mass index (BMI; in kg/m(2)), and liver enzymes. DESIGN Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT) were recorded from 2,164 apparently healthy participants (1,028 men, 1,136 women) reporting either no alcohol (abstainers) or <40 g ethanol consumption per day (moderate drinkers). The study population was further classified according to BMI as follows: <19 (underweight), > or =19 and <25 (normal weight), > or =25 and <30 (overweight), and > or =30 (obese). RESULTS Serum ALT (P < 0.05) and GGT (P < 0.001) but not AST (P = 0.805) activities in moderate drinkers were higher than those in abstainers. For all enzymes, a significant main effect was observed of increasing BMI, which was more striking in moderate drinkers than in abstainers. Tests of between-subjects effects indicated significant interactions with sex and drinking status, although not with sex and BMI. CONCLUSIONS The effect of moderate alcohol consumption on liver enzymes increases with increasing BMI. These findings should be considered in the clinical assessment of overweight alcohol consumers and in the definition of normal ranges for liver enzymes. These results may also help to develop new approaches for examining patients with fatty liver induced by either ethanol or adiposity.
