Attitudes toward weight gain in pregnancy.

Recently, there has been increased interest in the influence of maternal prenatal nutrition on the course and outcome of pregnancy. Evidence has accumulated that a woman's weight before pregnancy and the weight gained during pregnancy directly affect infant birth weight, incidence of neonatal mortality, and growth and development of the infant during the first year of life. Although recent recommendations for weight gain in pregnancy have been liberalized, a survey of 195 pregnant women who had prenatal visits in both clinic and private offices showed deficiencies in their understanding of the subject. Some 37 percent of women believed they should gain 20 pounds (9 kg) or less during pregnancy. Eight percent admitted to dieting before at least one antenatal visit and 54 percent thought their doctor would not be concerned about too little weight gained during pregnancy. This suggests that many women and some doctors are still ignorant of current concepts of proper nutrition during pregnancy. Apparently, increased lay and professional educational efforts are needed.

Observations on drug prescribing in rheumatoid arthritis.

A total of 125 patients with rheumatoid arthritis were investigated about their drug therapy before referral to a specialist centre. Most referrals were from general practitioners. Only 47 of the patients had received salicylates as the first drug and 18 had never had them at all. Soluble aspirin was the preparation of salicylates most frequently prescribed (for 63 patients). Only 60 patients had been given an adequate dose and only 62 an adequate course of treatment with salicylates. In 28 patients salicylates had been stopped on account of side effects. About one-third of the patients had been prescribed oral corticosteroids.The referral letters were poor in giving details of past and present drug therapy, and there were serious omissions in reporting of previous side effects.Seventy-five general practitioners were asked to rate several currently marketed antirheumatic drugs in terms of effectiveness. Though prednisolone 15 mg daily ranked higher than aspirin 4 g daily the difference was not significant. The study shows the inadequacies of drug prescribing for rheumatoid arthritis in the Glasgow area.

Expressive semantic deficit in the productive language of males with fragile X syndrome.

Eleven males with fragile x syndrome [fra(X)] between the ages of 6 and 41, with an average communication age of 4 years 4 months and 11 normally developing 4 year old boys were administered a sentence completion task that assessed expressive semantic competence. The fra(X) males produced significantly more semantic errors than the normally developing 4 year children. Additionally, it was shown that sentences which could be correctly completed by a wider choice of words affected fra(X) males more than the nondisabled children. These 2 results suggest that the expressive semantic system is an area of specific deficit in fra(X) males.

Regulation of proteasome complexes by gamma-interferon and phosphorylation.

Proteasomes play a major role in non-lysosomal proteolysis and also in the processing of proteins for presentation by the MHC class I pathway. In animal cells they exist in several distinct molecular forms which contribute to the different functions. 26S proteasomes contain the core 20S proteasome together with two 19S regulatory complexes. Alternatively, PA28 complexes can bind to the ends of the 20S proteasome to form PA28-proteasome complexes and PA28-proteasome-19S hybrid complexes have also been described. Immunoproteasome subunits occur in 26S proteasomes as well as in PA28-proteasome complexes. We have found differences in the subcellular distribution of the different forms of proteasomes. The gamma-interferon inducible PA28 alpha and beta subunits are predominantly located in the cytoplasm, while 19S regulatory complexes (present at significant levels only in 26S complexes) are present in the nucleus as well as in the cytoplasm. Immunoproteasomes are greatly enriched at the endoplasmic reticulum (ER) where they may facilitate the generation of peptides for transport into the lumen of the ER. We have also investigated the effects of gamma-interferon on the levels and subcellular distribution of inducible subunits and regulator subunits. In each case gamma-interferon was found to increase the level but not to alter the distribution. Several subunits of proteasomes are phosphorylated including alpha subunits C8 (alpha7) and C9 (alpha3), and ATPase subunit S4 (rpt2). Our studies have shown that gamma-interferon treatment decreases the level of phosphorylation of proteasomes. We have investigated the role of phosphorylation of C8 by casein kinase II by site directed mutagenesis. The results demonstrate that phosphorylation at either one of the two sites is essential for the association of 19S regulatory complexes and that the ability to undergo phosphorylation at both sites gives the most efficient incorporation of C8 into the 26S proteasome.

Non-steroid anti-inflammatory drug associated ulcer: epidemiology, causation and treatment.

Epidemiological evidence consistently indicates that aspirin or non-aspirin non-steroidal anti-inflammatory drug use is associated with the occurrence of gastric ulceration, gastric and ulcer bleeding, and ulcer death. Evidence on duodenal ulcer occurrence conflicts, possibly because of differences in study populations. A wide range of mechanisms could explain the occurrence of non steroidal-induced damage. These include inhibition of bicarbonate secretion, effects on mucus formation, and vascular actions. Not all effects are dependent on cyclo-oxygenase inhibition. Short-term studies in humans provide indications of likely therapeutic effects, but cannot demonstrate clinical efficiency. Although anti-secretory drugs and prostaglandins can protect patients against the development of duodenal or gastric ulcers, but not both, there is no clinical evidence which bears upon the critical issue of protection against complications.

Developmental supervision for nurses.

Developmental supervision is gaining increasing recognition in nursing as a form of clinical supervision that will promote professional growth and ultimately lead to improved patient care. Benner's (1984) model of career development is used as a framework in which to examine appropriate forms of supervision for each developmental stage. Directive, collaborative and non-directive supervision are applied to each of these developmental levels.

OMERACT: an international initiative to improve outcome measurement in rheumatology.

OMERACT is the acronym for an international, informally organized network aimed at improving outcome measurement in rheumatology. Chaired by an executive committee it organizes consensus conferences in a 2-yearly cycle that circles the globe since 2002. Data driven recommendations are prepared and updated by expert working groups. Recommendations include core sets of measures for most of the major rheumatologic conditions. Since 2002 patients have been actively engaged in the process. OMERACT 8 will take place in Malta, May 2006 (www.omeract.org).

A comparative study of auranofin, gold sodium thiomalate, and D-penicillamine in rheumatoid arthritis: a progress report.

We compared auranofin (AF) in a single blind multi-centre study with gold sodium thiomalate and D-penicillamine in the treatment of rheumatoid arthritis. Adult patients with disease duration 6-60 months without previous treatment with gold salts with persistent active disease, were included. Thirty-nine patients, 13 in each treatment group, have so far been entered. Cumulative toxicity data and some results of efficacy assessments in those completing 9 months of treatment are presented. AF is very well tolerated, judgment concerning efficacy must await the end of the trial.
