Abstract Context and Objectives The Controlled Antenatal Thyroid Screening Study I (CATS-I) was a randomized controlled trial investigating the effects of levothyroxine therapy for suboptimal gestational thyroid function (SGTF), comparing outcomes in children of treated (SGTF-T) with untreated (SGTF-U) women during pregnancy. This follow-up study, CATS-II, reports the long-term effects on anthropometric, bone, and cardiometabolic outcomes in mothers and offspring and includes a group with normal gestational thyroid function (NGTF). Design & Participants 332 mothers (197 NGTF, 56 SGTF-U, 79 SGTF-T) aged 41.2±5.3 years (mean±SD) and 326 paired children assessed 9.3±1.0 years after birth for (i) body mass index (BMI); (ii) lean, fat, and bone mass by dual-energy X-ray absorptiometry; (iii) blood pressure, augmentation index, and aortic pulse-wave-velocity; and (iv) thyroid function, lipids, insulin, and adiponectin. The difference between group means was compared using linear regression. Results Offspring’s measurements were similar between groups. Although maternal BMI was similar between groups at CATS-I, after 9 years (at CATS-II) SGTF-U mothers showed higher BMI (median [interquartile ratio] 28.3 [24.6-32.6] kg/m2) compared with NGTF (25.8 [22.9-30.0] kg/m2; P = 0.029), driven by fat mass increase. At CATS-II SGTF-U mothers also had higher thyroid-stimulating hormone (TSH) values (2.45 [1.43-3.50] mU/L) than NGTF (1.54 [1.12-2.07] mU/L; P = 0.015), since 64% had never received levothyroxine. At CATS-II, SGTF-T mothers had BMI (25.8 [23.1-29.8] kg/m2, P = 0.672) and TSH (1.68 [0.89-2.96] mU/L; P = 0.474) values similar to NGTF mothers. Conclusions Levothyroxine supplementation of women with SGTF did not affect long-term offspring anthropometric, bone, and cardiometabolic measurements. However, absence of treatment was associated with sustained long-term increase in BMI and fat mass in women with SGTF.

Objective: In the past years the interaction of GH and 11βhydroxysteroid dehydrogenase (11βHSD) in the pathogenesis of central obesity has been suggested. Design: We studied the effects of 9 months of GH treatment on 11βHSD activity and its relationship with body composition and insulin sensitivity in 30 men with abdominal obesity, aged 48–66 years, in a randomised, double-blind, placebo-controlled trial. Methods: Urinary steroid profile was used to estimate 11βHSD type 1 and 2 (11βHSD1 and 11βHSD2) activities. Abdominal s.c. and visceral adipose tissues were measured using computed tomography. Glucose disposal rate (GDR) obtained during a euglycaemic–hyperinsulinaemic glucose clamp was used to assess insulin sensitivity. Results: In the GH-treated group the 11βHSD1 activity decreased transiently after 6 weeks (P < 0.01) whereas 11βHSD2 increased after 9 months of treatment (P < 0.05). Between 6 weeks and 9 months, GDR increased and visceral fat mass decreased. Changes in 11βHSD1 correlated with changes in visceral fat mass between baseline and 6 weeks. There were no significant correlations between 11βHSD1 and 11βHSD 2 and changes in GDR. Discussion: The study demonstrates that short- and long-term GH treatment has different effects on 11βHSD1 and 11βHSD2 activity. Moreover, the data do not support that long-term metabolic effects of GH are mediated through its action on 11βHSD.

AbstractAspirin and nicametate are well-established therapies for preventing recurrence and mortality from stroke in patients diagnosed as ischemic stroke. However, their respective effects on the recurrence, making allowance for the duration of recurrence and death without the occurrence of recurrence, and long-term survival have not been well elucidated. We aimed to evaluate long-term effect of two kinds of treatment on cerebrovascular death among ischemic stroke patients with or without the recurrence of stroke. Data used in this study were derived from the cohort based on a multicenter randomized double-blind controlled trial during 1992 to 1995 with the enrollment of a total of 466 patients with first-time non-cardioembolic ischemic stroke who were randomly allocated to receive aspirin (n = 222) or nicametate (n = 244). The trial cohort was followed up over time to ascertain the date of recurrence within trial period and death until Sep of 2019. The time-dependent Cox regression model was used to estimate the long-term effects of two treatments on death from cerebrovascular disease with and without recurrence. A total of 49 patients experienced stroke recurrence and 89 cerebrovascular deaths was confirmed. Patients treated with nicametate were more likely, but non statistically significantly, to have recurrence (aHR: 1.73, 95% CI 0.96–3.13) as compared with those treated by aspirin. Nicametate reduced the risk of cerebrovascular death about 37% (aHR: 0.63, 95% CI 0.41–0.97) compared with aspirin. The aspirin group had a lower recurrence rate than the nicametate group even with recurrence after 1–2 years of follow-up of first stroke but the latter had significantly reduced death from cerebrovascular disease for nicametate group, which requires more research to verify.

ABSTRACT We have studied the chronic effects of TSH (100μU/ml) and insulin (10μg/ml) on intracellular pH (pHi) in FRTL-5 cells using the pH sensitive probe 2′7-bis (2-carboxyethyl-5′-6′) carboxyfluorescein. FRTL-5 cells were cultured on Petri dishes either in the presence of 4H, ie. Coons F-12 containing cortisol (10nM), transferrin (0.5μg/ml), glycyl-histidyl lysine acetate (10ng/ml) and somatostatin (10μg/ml), or with 4H+insulin (5H), 4H+TSH, or 4H+TSH+insulin (6H). pHi was measured in small groups of cells by microspectrofluorimetry both in the presence and absence of bicarbonate ions after cells had been deprived of serum for at least a day.

Introduction: Transcatheter aortic valve implantation (TAVI) is a procedure that alters dramatically the hemodynamics in patients with severe aortic valve stenosis who undergo this procedure. Hypothesis: We investigated the hypothesis that arterial properties and hemodynamics are affected immediately after TAVI as well as in the long-term. Methods: We enrolled 90 patients (mean age 80.2 ± 8.1 years, 50% males) with severe symptomatic aortic stenosis undergoing TAVI. Carotid-femoral and brachial-ankle pulse wave velocity (cfPWV and baPWV) were used for the assessment of arterial stiffness. Augmentation index corrected for heart rate (AIx@75) and subendocardial viability ratio (SEVR) were measured non-invasively. Measurements were conducted at baseline, after the procedure (during hospitalization) and at 1 year. Results: Acutely after TAVI we observed a statistically significant increase in arterial stiffness (7.5 ± 1.5 m/s vs 8.4 ± 1.9 m/s, p=0.001 for cfPWV and 1,773 ± 459 cm/s vs 2,383 ± 645 cm/s, p<0.001 for baPWV) without a concomitant change in systolic blood pressure (Figure). One year later, arterial stiffness was still increased compared to pre-TAVI measurements (7.5 ± 1.5 m/s vs 8.7 ± 1.7 m/s, p<0.001 for cfPWV and 1,773 ± 459 cm/s vs 2,286 ± 575 cm/s, p<0.001 for baPWV). We also found a decrease in AIx@75 (32.2 ± 12.9 % vs 27.9± 8.4 %, p=0.016) after TAVI that was attenuated at 1-year follow-up (32.2 ± 12.9 % vs 29.8± 9.1 %, p=0.38). SEVR displayed an increase acutely after TAVI (131.2 ± 30.0 % vs 148.4± 36.1 %, p=0.002) and remained improved 1 year after the procedure (131.2 ± 30.0 % vs 146± 32.2 %, p=0.01). Conclusions: In conclusion, shortly after TAVI the aorta exhibits a "stiffer" behavior in response to the acute change in hemodynamics, which settles in the long term. Our findings further elucidate the hemodynamic consequences of TAVI and may entail a prognostic role in this growing population.
