Is there an association between self-reported warm-up behaviour and golf related injury in female golfers?

Golfing injuries have been shown to occur frequently, and injury countermeasures have been suggested to help reduce injury risk. Performing an appropriate warm-up is thought to reduce injury risk, however there is a lack of evidence to support this notion. Therefore this study aimed to investigate the relationships between warm-up participation and injury in a cohort of female golfers. A total of 522 golfers participating in the Victorian Women's Pennant Competition completed the study. Over one-third (35.2%) of the golfers reported having sustained a golfing injury within the previous 12 months, with the lower back the most commonly injured region. Most golfers reported not warming-up prior to play or practice. Golfers who reported not warming-up on a regular basis were more likely to have reported a golfing injury in the previous 12 months than those reporting frequent warm-up participation (OR=45.2; 95% CI: 13.5, 151.7). Less skilled golfers were also less likely to report sustaining a golfing injury than more skilled golfers (OR=0.2; 95% CI: 0.1, 0.5). This study is one of the few to establish an association between warm-up participation and injury. Further prospective studies are warranted to determine whether warm-up reduces injury risk for golf participation.     

Factors affecting breastfeeding among women of Mexican origin or descent in Los Angeles.

Data on breastfeeding intentions and behavior were collected in prenatal and postpartum interviews as part of a study on first birth among 518 women of Mexican origin or descent in two Los Angeles hospitals. The prenatal intentions of 82 per cent of the women to breastfeed were maintained postpartum in one hospital but dropped sharply in the other. A greater number of hours a day with the baby in the hospital and earlier initiation of breastfeeding were associated with the hospital where prenatal breastfeeding intentions were more likely to be carried out. The intention to work postpartum was associated both with the decision not to breastfeed at all and with shorter intended duration of breastfeeding.     

Determining client need in a multi-state fetal alcohol syndrome consortium: from training to practice

Background  

A multi-state consortium was developed in the US to conduct baseline data collection and intervention research on fetal alcohol syndrome. Each state employed support specialists whose job it was to reduce or eliminate alcohol consumption in women who were at high risk for drinking alcohol during their pregnancy. The purpose of this paper is to report how support specialists in three primarily rural/frontier states were trained to assess client need and how client need was actually assessed in the field.     

Increased risk of pneumococcal infections in cardiac transplant recipients

We observed 5 episodes of pneumococcal infection among 129 cardiac transplant patients between March 1985 and December 1987, giving an estimated incidence of 36 cases per 1000 patient-years. Infections occurred a mean of 58 days after transplantation and included bacteremia with empyema, bacteremia alone, and pneumonia. All patients recovered from their infections. There was no correlation between infection and age, sex, immunosuppression, or rejection episodes. We also measured antibody levels to 12 pneumococcal antigens in 6 unvaccinated, uninfected patients before and after cardiac transplantation, to see if baseline antibody levels decreased. Protective levels of antibody were defined as greater than or equal to 300 ng of anticapsular antibody nitrogen per milliliter serum. Before transplantation patients had protective antibody levels to a mean of 8.7 +/- 1.2 pneumococcal serotypes; after transplantation, the number of presumably protective antibody levels decreased to 6.5 +/- 1.4 (P = 0.021). One of these patients subsequently developed pneumococcal pneumonia. Cardiac transplant patients are at increased risk of pneumococcal infections. Vaccinating transplant candidates prior to transplantation may provide protection after transplantation.     

Psychiatric morbidity in patients with life-threatening asthma: initial report of a controlled study

Thirteen patients who have suffered a "near-miss" death of asthma have been compared to 36 patients with asthma who had not experienced such an episode. Contrary to expectations, there were no differences between the groups in their levels of psychiatric morbidity, their degree of life-style and social restrictions or in their levels of compliance with prescribed medication. However, both groups did show higher than expected levels of psychiatric morbidity, severe life-style and social restrictions and an unexpectedly-high compliance with prescribed medication. The main psychiatric diagnoses that were noted were anxiety disorders. It is concluded that more comprehensive asthma education and close medical follow-up are likely to improve the physical and psychological health of asthmatic patients. The high-risk patients in this study who received such follow-up have shown hospital-admission rates that have been reduced by a half while maintaining good asthma control. This South Australian longitudinal study is continuing.     

Homeostasis and the age-associated defect of CD4 T cells

Survival and homeostatic division of naive CD4 T cells is regulated by the cellular and non-cellular milieu and together these processes ensure that a population of naive CD4 T cells persists into old age. However, the naive CD4 T cells from aged animals show reduced IL-2 production, proliferation, helper function and effector generation and memory function. We explore here whether the age-related defects in naive CD4 T cells are due to the aged environment from which they come or to intrinsic defects that are caused by homeostasis and their long lifespan.
