OBJECTIVES Stress systems may be altered in the long term in preterm infants for multiple reasons, including early exposure to procedural pain in neonatal intensive care. This question has received little attention beyond hospital discharge. Stress responses (cortisol) to visual novelty in preterm infants who were born at extremely low gestational age (ELGA; < or =28 weeks), very low gestationa...

Background: There is a paucity of evidence regarding long-term outcomes of late preterm (34-36 weeks) and early term (37-38 weeks) delivery.  The objective of this systematic review was to assess long-term cognitive outcomes of children born at these gestations. Methods: Four electronic databases (Medline, Embase, clinicaltrials.gov and PsycINFO) were searched.  Last search was 5 th August 2016...

The aim of this study was to recognize the effects of dietary hempseed (HS) and hempseed oil (HO) on performance, egg quality and blood parameters of laying hens. A total of 320 Hy-line 55-weeks laying hens were randomly allotted to eight dietary treatments with five replicates (8 birds each). The experimental treatments were offered as a completely randomized design as follow: control group (n...

BACKGROUND AND PURPOSE In chronic hydrocephalus, a role for tissue hypoxia resulting from cerebrovascular compression is suggested. The purpose of this study was to evaluate whether changes in cerebral blood flow (CBF) in the time course of adult kaolin-induced hydrocephalus correlated with immunohistochemical neuronal responses. METHODS In 46 adult Sprague-Dawley rats, kaolin hydrocephalus w...

Material Patients.-39 patients were studied, all but one of whom had taken prednisone 5 mg./day for periods of from 8 weeks to 8 years. One patient (Case 31) had her dose increased from 5 to 7 mg./day 8 months before the test. With the exception of two who had polymyalgia rheumatica, all had rheumatoid arthritis. Of these 39 patients, nineteen were selected at random and studied again after a y...

this research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. for that, 312 day-old male ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. diets include...

QUESTIONS Do patients with a severe ankle injury (baseline ankle function score < or = 40) do worse in the short-term than patients with a mild injury (score > 40)? Does physiotherapy intervention have more effect on patients with a severe injury compared with a mild injury in the short- or long-term? Is self-reported recovery related to ankle function score over time? DESIGN Subgroup analysi...

Despite substantial improvements in solid culture media for gonococci and the development of liquid media for the short-term growth of the organism, we know of no study of the long-term survival of Neisseria gonorrhoeae in liquid medium. A new liquid medium for N. gonorrhoeae formulated in this laboratory is simple, efficient, and promising. It will support growth and sustain inoculated colony ...

OBJECTIVE The objective of this paper is to describe the course "Systematic Reviews and Meta-analysis" at the Johns Hopkins Bloomberg School of Public Health. METHODS A distinct feature of our course is a group project in which students, assigned to multi-disciplinary groups, conduct a systematic review. In-class sessions comprise didactic lectures, hands-on exercises, demonstrations, discuss...

Recently, worldwide dietary reference intakes have been considered an important guideline for public health. Some governments and the World Health Organization (WHO) provide guidelines concerning dietary intake. Although an ingredient may have a history of use as a culinary material, changes in the environment over time suggest that the acceptable maximum intake each of food/culinary material s...
