Low maternal vitamin D levels in pregnancy may be associated with an increased risk of preeclampsia, GDM, preterm birth and SGA.

In prevention trials, early intervention with amniotomy and oxytocin appears to be associated with a modest reduction in the rate of caesarean section over standard care.

To estimate the associations between vitamin D status and Parkinson's disease (PD). We searched electronic databases of the human literature in PubMed, EMBASE and the Cochrane Library up to February, 2014 using the following keywords: 'vitamin D' or '25(OH)D' and 'status' or 'deficiency' or 'insufficiency' and 'Parkinson's disease'. A systematic review and meta-analysis were conducted on observational studies that reported the association between blood vitamin D levels and PD. Seven studies met the inclusion criteria. 1,008 patients and 4,536 controls were included. Results of our meta-analysis show that PD patients had lower mean levels of 25-hydroxyvitamin D [25(OH)D] than healthy controls [weighted mean difference (MD), -16.9, 95 % confidence interval (CI)], -33.5 to -0.2). Patients with vitamin D insufficiency [25(OH)D level <75 nmol/l] had an increased risk of PD (OR 1.5, 95 % CI 1.1-2.0). Patients with vitamin D deficiency [25(OH)D level <50 nmol/l] experienced a twofold increased risk of PD (OR 2.2, 95 % CI 1.5-3.4). Low vitamin D levels are associated with an increased risk of PD.

Within 3 mo, IVTA is more effective than is STTA in improving VA and reducing CMT in patients with refractory DME. However, the benefits of either regimen were no longer evident at 6 mo.
