Improvements in processing speed following fish-oil supplementation in middle-aged to older males might be mediated by improvements in circulatory function. Mechanisms underlying the cognitive benefit seen with curcumin are unknown. As cognitive benefits were found in males only, further evaluation of sex differences in responsiveness to supplementation is warranted.

Under basal insulin levels, there is an inverted U relationship between exercise intensity and exogenous glucose requirements to maintain stable blood glucose levels in type 1 diabetes (T1D), with no glucose required for intense exercise (80% V̇O2 peak), implying that high-intensity exercise is not conducive to hypoglycemia.

This work aimed to test the hypothesis that a similar inverted U relationship exists under hyperinsulinemic conditions, with high-intensity aerobic exercise not being conducive to hypoglycemia.

Nine young adults with T1D (mean ± SD age, 22.6 ± 4.7 years; glycated hemoglobin, 61 ± 14 mmol/mol; body mass index, 24.0 ± 3.3 kg/m2, V̇O2 peak, 36.6 ± 8.0 mL·kg-1 min-1) underwent a hyperinsulinemic-euglycemic clamp to maintain stable glycemia (5-6 mmol·L-1), and exercised for 40 minutes at 4 intensities (35%, 50%, 65%, and 80% V̇O2peak) on separate days following a randomized counterbalanced study design.

Glucose infusion rates (GIR) and glucoregulatory hormones levels were measured.

The GIR (± SEM) to maintain euglycemia was 4.4 ± 0.4 mg·kg-1 min-1 prior to exercise, and increased significantly by 1.8 ± 0.4, 3.0 ± 0.4, 4.2 ± 0.7, and 3.5 ± 0.7 mg·kg-1 min-1 during exercise at 35%, 50%, 65%, and 80% V̇O2 peak, respectively, with no significant differences between the 2 highest exercise intensities (P > .05), despite differences in catecholamine levels (P < .05). During the 2-hour period after exercise at 65% and 80% V̇O2 peak, GIRs did not differ from those during exercise (P > .05).

Under hyperinsulinemic conditions, the exogenous glucose requirements to maintain stable glycemia during and after exercise increase with exercise intensity then plateau with exercise performed at above moderate intensity ( > 65% V̇O2 peak). High-intensity exercise confers no protection against hypoglycemia.

However, rigorous evaluations of such programmes in urban contexts are lacking. We used a retrospective, cross-sectional with comparison group design to estimate the immediate and sustained impact of the Willows intervention on modern contraceptive use in Kumasi, Ghana. The Willows intervention is a home-based counselling and referral programme for women in low-income urban settlements. We analysed data from a cross-sectional representative survey of 1205 women of reproductive age in the intervention area and 1108 women in a matched comparison site. learn more The main outcome was women's reported contraceptive use at (1) baseline (January 2013); (2) programme close (December 2016); and (3) follow-up (August to October 2018). We estimated the programme effect at the community level and for women who reported receiving a family planning counselling visit. We used coarsened exact matching to assess the impact of the intervention relative to outcomes for matched comparison women. Comparing those who reported a family planning visit in the intervention area with matched comparison area women who reported no visit, we estimated a 10.5 percentage point increase in use of modern contraceptives from baseline to close (95%CI 6.2, 14.8; P  less then  0.001) and a 7.6 percentage point increase from baseline to follow-up (95%CI 3.3, 11.9; P  less then  0.001). However, only 20.2% of women in the Willows intervention area reported a visit. The Willows intervention, therefore, did not achieve its aim to reach all reproductive-aged women in the community. At the community level, we found no significant effect of the intervention at either programme close or 2 years later. We recommend that similar community-based interventions strive for greater outreach and simultaneously launch robust prospective impact evaluations.
Synovitis in symptomatic knee OA (KOA) is common and is associated with joint symptoms. Optimal synovial measurement on MRI is, however, unclear. Our aims were to examine the relationship between MRI measures of synovitis and knee symptoms in symptomatic KOA.

Data from a randomized, multicentre, placebo-controlled trial (UK-VIDEO) of vitamin-D therapy in symptomatic KOA were utilized. Participants reported knee symptoms using WOMAC at baseline and annually. On contrast-enhanced (CE) MRI, synovial thickness was measured using established, semi-quantitative methods whilst synovial tissue volume (STV) was assessed as absolute STV (aSTV) and relative to the width of femoral condyle (rSTV). STV of the infrapatellar region was also assessed. Associations between synovial measures and symptoms were analysed using multiple linear regression modelling.

No linear association was observed between knee symptoms and synovitis thickness scores. Whole-joint aSTV (0.88, 95% CI 0.17, 1.59) and infrapatellar aSTV (5.96, 95% CI 1.22, 10.7) were positively associated with knee pain. Whole-joint rSTV had a stronger association with pain (7.96, 95% CI 2.60, 13.33) and total scores (5.63, 95% CI 0.32, 10.94). Even stronger associations were found for infrapatellar rSTV with pain (55.47, 95% CI 19.99, 90.96), function (38.59, 95% CI 2.1, 75.07) and total scores (41.64, 95% CI 6.56, 76.72).

Whole-joint and site-specific infrapatellar STV measures on CE-MRI were associated with knee pain, respectively. Volumes relative to the size of the femoral condyle may be promising outcome measures in KOA trials.
