Randomized Controlled Trial Multicenter Study
Iron Supplementation in Iron-Replete and Nonanemic Pregnant Women in Tanzania: A Randomized Clinical Trial.
Anemia is common in pregnancy and increases the risk of adverse outcomes. Iron deficiency is a leading cause of anemia in sub-Saharan Africa, and iron supplementation is the standard of care during pregnancy; however, recent trials among children have raised concerns regarding the safety of iron supplementation in malaria-endemic regions. There is limited evidence on the safety of iron supplementation during pregnancy in these areas. ⋯ Prenatal iron supplementation among iron-replete, nonanemic women was not associated with an increased risk of placental malaria or other adverse events in the context of good malaria control. Participants receiving supplementation had improved hematologic and iron status at delivery compared with the placebo group. These findings provide support for continued administration of iron during pregnancy in malaria-endemic regions.

Randomized Controlled Trial
The effects of a diet rich in inulin or wheat fibre on markers of cardiovascular disease in overweight male subjects.
Previous studies suggest that the beneficial health effects of a diet rich in whole grains could be a result of the individual fibres found in the grain. The present study aimed to investigate the influence of a diet high in either wheat fibre (as an example of an insoluble fibre) or inulin (a nondigestible carbohydrate) on markers of cardiovascular disease. ⋯ Only limited differences between the interventions were identified, perhaps as a consequence of the amount of fibre used and intervention length. The wheat germ intervention resulted in a significant reduction in glucose area under the curve, suggesting that this fibre may aid glucose control.

Clinical Assessment of Fluid Balance is Incomplete for Colorectal Surgical Patients.
Fluid balance for the surgical patient has been proven very important for the postoperative outcome and development of complications. The aim of this study was to evaluate, for the first time in modern times, the accordance between nurse-based fluid charting (cumulated fluid balance) and body weight change for general surgical patients. ⋯ The accordance between cumulated fluid balance and body weight change for colorectal surgical patients is relatively good for the first four postoperative days, however, with large uncertainty, whereas on the fifth and sixth postoperative day, the discrepancy is statistically and clinically significant. The fluid chart cannot stand alone in interpretation of the patient's fluid balance; body weight and clinical judgment is indispensable.

Efficacy and safety of tralokinumab in patients with severe uncontrolled asthma: a randomised, double-blind, placebo-controlled, phase 2b trial.
Interleukin 13 is a central mediator of asthma. Tralokinumab is a human interleukin-13 neutralising monoclonal antibody. We aimed to assess the efficacy and safety of two dosing regimens of tralokinumab in patients with severe uncontrolled asthma. ⋯ MedImmune.

Randomized Controlled Trial
Anxiety-provoked gait changes are selectively dopa-responsive in Parkinson's disease.
In order to understand how dopamine modulates the effect of anxiety on gait, the goal of this study was to use virtual reality to provoke anxiety in Parkinson's disease (PD) (in both ON and OFF states) and quantify its effect on gait. Seventeen participants with PD and 20 healthy age-matched controls were instructed to walk in a virtual environment in two anxiety-provoking conditions: (i) across a plank that was located on the GROUND and (ii) across an ELEVATED plank. All participants with PD completed this experiment in both the ON and OFF states, and were then striated into groups based on baseline trait anxiety scores for further analyses. ⋯ OFF comparison). In conclusion, only highly trait anxious participants with PD benefitted from dopaminergic treatment, specifically when walking in the anxiety-provoking environment. Improvements to gait during anxious walking might be a result of dopaminergic medication acting in two ways: (i) improving the basal ganglia's capacity to process information and (ii) reducing the load from anxiety and subsequently making more resources available to effectively process other competing inputs.
