RESUMEN
(1) Hyperglycemia and oral pathology accelerate each other in diabetes. We evaluated whether gestational diabetes mellitus (GDM) is associated with self-reported increased oral health care needs and oral symptoms, including third molar symptoms, during pregnancy. (2) Pregnant women with (n = 1030) and without GDM (n = 935) were recruited in this multicenter Finnish Gestational Diabetes study in 2009-2012. Of the women with GDM, 196 (19.0%) receiving pharmacological treatment, 797 (77.0%) receiving diet treatment and 233 (23.0%) with recurrent GDM were analyzed separately. Oral health was assessed using structured questionnaires and analyzed by multivariable logistic regression adjusted for background risk factors. (3) Women with GDM were more likely to report a higher need for oral care than controls (31.1% vs. 24.5%; odds ratio (OR) 1.39; 95% confidence interval (CI) 1.14-1.69), particularly women with recurrent GDM (38.1% vs. 24.5%; OR 1.90; 95% CI 1.40-2.58). Women with pharmacologically treated GDM (46.9%) more often had third molar symptoms than controls (36.1%; OR 1.57; 95% CI 1.15-2.15) than women with diet-treated GDM (38.0%; OR 1.47; 95% CI 1.07-2.02). (4) GDM is associated with perceived oral care needs. Third molar symptoms were associated with pharmacologically treated GDM.

OBJECTIVES: Altered intestinal permeability and gut barrier dysfunction have been suggested to play a role in the pathogenetic mechanism of polycystic ovary syndrome (PCOS), the most common endocrine and metabolic condition in reproductive-aged women. However, data on intestinal permeability and dysbiosis of the gut microbiota in PCOS is still limited, with conflicting results. To this end, the concentrations of gastrointestinal permeability and gut dysbiosis markers were analysed in women with PCOS. DESIGN: Case-control study. SETTING: General community. PARTICIPANTS: 104 women with PCOS and 203 body mass index (BMI) matched control women at age 46. PRIMARY AND SECONDARY OUTCOME MEASURES: Serum levels of zonulin, fatty acid-binding protein 2 (FABP2), urinary levels of indican, and hormonal and metabolic parameters. RESULTS: Serum levels of zonulin (128.0±17.0 vs 130.9±14.0 ng/mL, p=0.13) and FABP2 (1.5±0.9 vs 1.5±0.7 ng/mL, p=0.63) and urinary levels of indican (9.5±5.5 vs 8.4±4.2 mg/dL, p=0.07) were comparable in women with PCOS and controls in the whole study population. Likewise, when the study population was divided into different BMI groups as normal weight, overweight and obese, the levels of the above markers were comparable between the study groups. After BMI adjustment, zonulin levels correlated with the levels of high-sensitivity C reactive protein and homoeostasis model assessment of insulin resistance (p<0.05) both in women with PCOS and controls. CONCLUSIONS: Intestinal permeability markers zonulin and FABP2, and the dysbiosis marker indican do not seem to be altered in women with PCOS at age 46 compared with BMI-matched controls. Serum zonulin levels correlated with BMI, insulin resistance and inflammatory marker levels, but did not segregate women with PCOS and controls. This suggests that metabolic factors, but not PCOS per se, is the driving force of dysbiosis in premenopausal women with PCOS.

OBJECTIVE: To study the effects of metformin treatment on bone turnover in women with polycystic ovary syndrome (PCOS), as measured by serum concentrations of bone turnover markers. DESIGN: Post hoc study of a previously conducted prospective multicenter, placebo-controlled, randomized study. SETTING: University clinic. PATIENT(S): The study cohort consisted of 74 non-obese women (body mass index < 27 kg/m2) and 44 obese women (body mass index ≥ 27 kg/m2) diagnosed with PCOS, with a mean age of 27.6 ± 4.0 (SD) years. INTERVENTION(S): Randomization to receive metformin or placebo for 3 months. MAIN OUTCOME MEASURE(S): Serum levels of bone formation marker procollagen type I amino-terminal propeptide (PINP) and bone resorption marker carboxy-terminal cross-linking telopeptide of type I collagen (CTX) at baseline and after metformin/placebo treatment. RESULT(S): Serum levels of PINP and CTX were similar between the metformin and placebo groups at baseline in the whole study population. Obese women, when compared with non-obese, had lower baseline levels of PINP and CTX. Levels of PINP and CTX were significantly reduced in the whole study population, as well as in both non-obese and obese women after 3 months of metformin treatment, whereas no significant changes were observed in the placebo group. CONCLUSION(S): Metformin treatment, when compared with placebo, was associated with reduced bone turnover, as suggested by reductions in markers of bone formation and resorption, leading to slower bone remodeling in premenopausal women with PCOS. CLINICAL TRIAL REGISTRATION NUMBER: NCT00994812.

OBJECTIVE: Serum levels of retinol-binding protein 4 (RBP4), an adipokine thought to affect systemic insulin sensitivity, were compared between women with polycystic ovary syndrome (PCOS) and non-PCOS controls to evaluate the association of RBP4 with clinical, hormonal and metabolic parameters of PCOS. SUBJECTS AND METHODS: Serum RBP4 levels were analysed in 278 women with PCOS (age range 18-57 years) and 191 non-PCOS controls (age 20-53 years) by enzyme-linked immunosorbent assay. RESULTS: Serum levels of RBP4 were increased in women with PCOS compared with control women in the whole population (45.1 ± 24.0 (s.d.) vs 33.5 ± 18.3 mg/L, P < 0.001). Age-stratified analysis showed that serum RBP4 levels were increased in women with PCOS aged ≤30 years compared with controls (47.7 ± 23.5 vs 27.1 ± 10.4 mg/L, P < 0.001), whereas no significant differences were seen in the other age groups. No significant correlations of RBP4 were seen with either steroids or indices of insulin resistance. CONCLUSIONS: Although serum RBP4 levels were increased in younger women with PCOS compared with age-matched non-PCOS controls, RBP4 does not seem to be a good marker of insulin resistance or other metabolic derangements in women with PCOS.
RESUMEN
OBJECTIVE: Hyperandrogenism, hyperinsulinaemia and obesity, known characteristics of polycystic ovary syndrome (PCOS), may influence bone mineral density and biochemical markers of bone turnover (BTMs) can provide a noninvasive assessment of bone turnover. To this end, the serum concentrations of BTMs and 25-hydroxyvitamin D (25OHD) were analysed in women with PCOS, and their possible associations with metabolic parameters of PCOS were determined. SUBJECTS AND METHODS: Bone formation markers procollagen type I amino-terminal propeptide (PINP) and osteocalcin (OC), and bone resorption marker carboxy-terminal cross-linking telopeptide of type I collagen (CTX), along with 25OHD, were measured in 298 women with PCOS and 194 healthy controls. RESULTS: Serum levels of PINP (47.0 ± 20.2 vs 58.1 ± 28.6 µg/L, P < .001) and OC (18.2 ± 7.5 vs 20.6 ± 9.8 µg/L, P < .001) were decreased in women with PCOS compared with controls, whereas no significant differences were found in CTX and 25OHD levels. Age-stratified analyses suggested that PINP (50.5 ± 21.7 vs 68.2 ± 26.6 µg/L, P < .001) and OC levels (20.4 ± 7.6 vs 25.5 ± 9.6 µg/L, P < .001) were decreased only in the younger age group (≤30 years) women with PCOS compared with controls. The formation markers and resorption marker decreased with age in both study groups. CONCLUSIONS: Bone formation markers were decreased in younger women with PCOS when compared with healthy women, which may affect bone mass in these women.
