The past decade has witnessed a burst of study regarding antibiotic resistance in the environment, mainly in areas under anthropogenic influence. Therefore, impacts of the contaminant resistome, that is, those related to human activities, are now recognized. However, a key issue refers to the risk of transmission of resistance to humans, for which a quantitative model is urgently needed. This opinion paper makes an overview of some risk-determinant variables and raises questions regarding research needs.
Background Although structured psychological treatments are recommended as first-line interventions for depression, only a small fraction of people globally receive these treatments because of poor access in routine primary care. We assessed the effectiveness and cost-effectiveness of a brief psychological treatment (Healthy Activity Program [HAP]) for delivery by lay counsellors to patients with moderately severe to severe depression in primary health-care settings.
Rationale: Food insecurity has emerged as an important, and potentially modifiable, risk factor for depression. Few studies have brought longitudinal data to bear on investigating this association in sub-Saharan Africa. Objective: To estimate the association between food insufficiency and depression symptom severity, and to determine the extent to which any observed associations were modified by social support.
Purpose: To evaluate the efficacy and safety of intravitreal ranibizumab in diabetic macular edema (DME) patients. Design: Two parallel, methodologically identical, phase III, multicenter, double-masked, sham injectioncontrolled, randomized studies. Participants: Adults with vision loss from DME (best-corrected visual acuity [BCVA], 20/4020/320 Snellen equivalent) and central subfield thickness ≥275 μm on time-domain optical coherence tomography (OCT). Intervention: Monthly intravitreal ranibizumab (0.5 or 0.3 mg) or sham injections. Macular laser was available per-protocolspecified criteria.
