Background: Individuals from minority groups have historically faced social injustices. Those from underrepresented groups have been less likely to access both healthcare services and higher education. Little is known about the experiences of underrepresented students during their undergraduate studies in osteopathy in the UK.

However, it has not been formally tested whether the extent to which sham controls resemble the treatment under investigation consistently affects trial outcomes, such as effect sizes, differential attrition, participant expectancy, and blinding effectiveness. Placebo- or sham-controlled RCTs of PPS interventions of clinical pain populations were searched in 12 databases.

In order to improve interest in science among future professionals, appropriate techniques should be developed and employed to identify barriers and correlates of science education among pre-university students.

Methods: School-age children were enrolled in a cross-sectional study from April through July 2012. Stool and urine samples were examined respectively for helminths and Schistosoma haematobium.
The French National Authority for Health has made serious adverse event disclosure one of its priority areas of work. The objective of the study was to explore clinicians' perceived practices of disclosing such events. Between June and July 2012, a structured questionnaire was emailed to all clinicians and residents working at the Nantes Teaching Hospital.

This protein has been shown to be adaptively evolving in a number of animal and plant species. In a previous communication we were able to demonstrate that signs of adaptive evolution were detected in the comparison of CENP-A sequences from three percid fish species.

Several studies have demonstrated a strong association between CLBP and psychological factors such as anxiety, fear-avoidance, self-efficacy, catastrophizing and depression. These factors are closely linked with emotional states; however, it is unknown whether CLBP patients process their emotions differently from asymptomatic individuals.

Design: The tool was developed by a multidisciplinary panel of 33 experts, using a formalized consensus method. It collects both the needs of patients (distinguishing healthcare needs (9 criteria) and accommodation needs (9 criteria)) and the reasons for inappropriateness (19 criteria).

Objective: Inappropriate prescribing in elderly is considered as common (40% of subjects from community from the 3CStudy in France had a inappropriate prescription, using Beer's criteria), and can lead to severe issues. Few studies have assessed inappropriate prescribing for elderly inpatients in acute care, with multiple tools. Our study was designed to assess outcome prescriptions concordance of elderly inpatients, for potentially inappropriate medication use.

A literature review related to the last ten years found 38 publications, including 19 original studies. Results showed that only few studies were published, and that methodologies were not standardized.

In both habitats, the number of termites present in single stakes and stake-bundles increased with stake resource size, and the number of larvae recorded from feeding sites was a close reflection of the number of workers attracted to a given food source. Over 12 mo, more single stakes and stake bundles were heavily attacked and abandoned in the pine woods compared with grassy clearings.

Background: A relationship between Chlamydia pneumoniae infection and acute coronary syndromes has not been consistently found in published studies. It has been hypothesized that a bacteriophage-infected subset of C pneumoniae may be uniquely equipped to promote atherosclerosis and acute coronary syndromes through the expression of phage genes.
Methods: The authors performed a pilot case-control study of acute coronary events.
Tissue Doppler (TD) imaging is a novel echocardiographic technique that measures myocardial velocities. However, there are sparse data on TD imaging of the right ventricular (RV) free wall in the diagnosis and prognosis of RV myocardial infarction (MI) in inferior wall left ventricular MI. Fifty patients who had left ventricular MI underwent TD echocardiography and angiography within 48 hours of MI.

As early as 3 hr, a marked infiltration of macrophages and lymphocytes occurred in the reinfection group, while very little cell infiltration occurred in the primary group. It seems that only an antigen-antibody reaction could produce such an immediate pronounced antigen-specific chemotactic effect, because very few lymphocytes are normally present in the skin.

Laboratory strain Ravenel S (ATCC 35720) was not fully virulent. Fully virulent strains produce one visible primary pulmonary tubercle for each three bacillary units inhaled.

Background: Increased lipid peroxidation caused by oxygen free radicals is thought to be one of the common pathogenetic mechanisms for the so-called oxygen radical diseases of prematurity. Since in vitro studies have shown that various forms of vitamin A can exert antioxidant effects that are more potent than those of vitamin E (treatment with which has been ineffective in these diseases), the purpose of this prospective, controlled study was to determine whether administration of supplemental vitamin A to premature infants deficient in this vitamin would have an antioxidant effect in vivo.
Methods: Fourteen infants (1181 +/- 35 g; gestational age 29 +/- 0.

Background: The purpose of this study was to use the breath ethane test to determine if either maternal cigarette smoking, formula, and/or deficiency of the antioxidant nutrients vitamins A and E was associated with oxidant stress in newborn infants. The rationale for this study was: (1) our observation that cigarette smoking was a source of oxidant stress in pregnant women, suggesting that it could be a source of oxidant stress for infants exposed in utero; (2) formula was predicted to be prooxidant compared to colostrum, which contains several compounds with antioxidant activity in vitro; and (3) deficiencies of vitamins A and E have been shown to promote oxidant stress in experimental animals.
Methods: Breath ethane, a volatile alkane produced by peroxide of n-3 fatty acids, was utilized as an index of oxidant stress status.
Types and frequency of child abuse and neglect reports in family foster care in Baltimore, Maryland as compared to reports among nonfoster families are reported. Data on maltreatment incidents in foster homes were abstracted from Child Protective Services investigation records for the years 1984-1988. Comparisons were made to community reports.
