Does patient education improve compliance to routine diabetic retinopathy screening?

Introduction: Diabetic retinopathy (DR) screening relies on adherence to follow-up eye care. This article assesses if a model of patient education and tele-retina screening among high-risk patients with DR can achieve increased rates of compliance within a one-year follow-up.

Methods: Between May 2014 and May 2016, DR screening was conducted in a cohort of 101 patients with diabetes in Southern Ontario.

Predictors of functional vision changes after cataract surgery: the PROVISION study.

Objective: To ascertain whether time-to-treatment, sex, age, preoperative functional vision scores, education, and ocular comorbidities predict change in functional vision pre- to postoperatively in patients receiving cataract surgery.

Design: Prospective cohort study.

Participants: Three hundred and forty-three cataract patients at the Hamilton Regional Eye Institute.

Detection of Helicobacteraceae in intestinal biopsies of children with Crohn's disease.

Background: Given that members of Helicobacteraceae family colonize the intestinal mucus layer, it has been hypothesized that they may play a role in Crohn's disease. This study investigated the presence of Helicobacteraceae DNA in biopsies collected from children with Crohn's disease and controls.

Materials And Methods: The presence of Helicobacteraceae DNA was investigated in intestinal biopsies collected from 179 children undergoing colonoscopy (Crohn's disease n = 77, controls n = 102) using a Helicobacteraceae-specific PCR.

Postprandial mineral metabolism and secondary hyperparathyroidism in early CKD.

Normophosphatemia and normocalcemia are maintained in chronic kidney disease (CKD) by increased levels of fibroblast growth factor-23 (FGF-23) and parathyroid hormone (PTH), but the stimuli for secretion of these hormones in early CKD are incompletely understood. Most human physiologic studies have focused on random or fasting measurements of phosphorus, calcium, FGF-23, and PTH, but in this study, the hypothesis was that measurements in the postprandial state may reveal intermittent stimuli that lead to increased FGF-23 and PTH levels. The 4-h postprandial response in 13 patients with CKD and fasting normophosphatemia and normocalcemia (mean GFR 41 +/- 8 ml/min per m(2)) was compared with 21 healthy volunteers.

Fibroblast growth factor-23 mitigates hyperphosphatemia but accentuates calcitriol deficiency in chronic kidney disease.

Hyperphosphatemia, calcitriol deficiency, and secondary hyperparathyroidism (SHPT) are common complications of chronic kidney disease (CKD). Fibroblast growth factor-23 (FGF-23) is a novel phosphaturic hormone that also inhibits renal 1alpha-hydroxylase activity and thus may be involved in the pathogenesis of SHPT. Several hypotheses were tested: that FGF-23 increases as renal function declines; is linearly associated with serum phosphate levels; is associated with increased phosphaturia independent of parathyroid hormone (PTH); and is associated with decreased calcitriol levels independent of renal function, hyperphosphatemia, and vitamin D stores.

The relation of children's everyday nonsocial peer play behavior to their emotionality, regulation, and social functioning.

The relations of children's nonsocial behavior to their emotionality, regulation, and social functioning were examined in a short-term longitudinal study. Parents (primarily mothers) and teachers rated children's effortful regulation, emotionality, asocial behaviors, problem behaviors, and social acceptance, and children's nonsocial play behaviors were observed for two semesters. Peers also rated likability.
