A comparison of Gaelic football injuries in males and females in primary care

The Ladies Gaelic Football Association has a playing population of 150,000 of which 33% are adults. A number of studies have been published on rates of injury among male athletes but none on female athletes in Gaelic football. A retrospective review of insurance claims, submitted under the Gaelic Athletic Association Player Insurance Injury Scheme. 405 injuries were recorded, 248 [107 (70%) male, 141 (58%) female] to the lower limb, 91 [33 (21%) male, 58 (23%) female] to the upper limb. The majority of lower limb injuries [56 (52%) male, 56 (40%) female] were to muscle. Almost a third of upper limb injuries were fractures [10 (30.3%) male, 33 (57%) female]. injuries/1000 hours playing was 8.25 for men and 2.4 for women. The injury rate in ladies Gaelic football was found to be significantly lower than in men's Gaelic football. Lower limb injuries accounted for the majority of injuries in both sports.

Variations in truncal body circumferences affect fat mass quantification with bioimpedance analysis

OBJECTIVE

To test the hypothesis that variations in trunk circumferences influence the accuracy of bioimpedance analysis (BIA) for assessment of percent fat mass (%FM).

SUBJECTS AND METHODS

%FM was predicted with BIA, and compared with air-displacement plethysmography (ADP) in a small sample of 35 overweight (OW), 21 normal weight and 8 underweight volunteers. Waist and hip circumferences were assessed, and 15 of the OW subjects were measured before and after weight reduction.

RESULTS

BIA and ADP provided similar cross-sectional estimates of group mean %FM (28.9±10.0 and 31.3±13.0%, respectively). However, within individuals, there were large between-method differences (Diff(BIA-ADP)) ranging from -13 to +13 %FM. Furthermore, we found a systematic bias of BIA related to the degree of adiposity. Consequently, %FM and fat mass loss during weight reduction in OW were underestimated with BIA when compared with ADP. Waist and hip circumferences were inversely associated with resistance (R) and reactance (P<0.01), and with Diff(BIA-ADP) (P<0.001). In women, the variability in hip circumference explained 76%, and in men, the variability in waist circumference explained 59% of Diff(BIA-ADP).

CONCLUSION

Resistance changes associated with variations in trunk circumferences decrease resistance, and therefore impair the accuracy of BIA to assess %FM.

[An outpatient education program for patients and partners after implantation of implantable cardioverter defibrillators (ICD)]

BACKGROUND

The implantation of an implantable cardioverter defibrillator (ICD) is commonly followed by a physical and psychological process of adaptation to the new situation. Psychological support is often not provided and patients are left alone with questions and their needs. Because of the emerging sense of support group programs have proven to be apt for clearing up questions and addressing personal concerns. In the present study a psychoeducational program is presented and evaluated in detail.

MATERIAL AND METHODS

A total of 308 patients with ICDs as well as their partners participated in a 2 day psychoeducational program. Of the patients 100 as well as their partners were asked to complete questionnaires concerning anxiety and depression (HADS) as well as their satisfaction with the program. The program consists of five modules: a warm up and getting to know each other; medical and technical information concerning the ICD, psychoeducation concerning the topics anxiety and avoidance, relaxation and an experience report of a patient who has had an ICD for many years.

RESULTS

The evaluation results of 72 participants are present. All patients would definitively recommend participation in the program to other patients with an ICD without restrictions. The satisfaction with the five different modules of the intervention was very high. The depression as well as the anxious symptomatology in the HADS decreased significantly in the 1 year follow-up but did not exceed the cut-off point of 8. The anxiety and depression symptoms of the partners decreased significantly and exceeded the cut-off point of 8 in the follow-up.

[Psychocardiological practice guidelines for ICD implantation and long-term care]

In the literature there are only very few reports on systematic education or information for patients after implantation. Research in this field has only just begun so that there are no sufficiently evaluated models which could serve as the foundations for recommendations. Approximately 80% of affected patients, relatives and partners show a good cognitive acceptance and are capable of coping with the situation. However, in the first 12 months following ICD implantation some 20% of patients are in a state of anxiety and depression. These patients must be recognized and if necessary treated and given support. For this reason it is important in the consultation and routine appointments to give patients the chance to express their views on this if necessary. Only then can cardiologists recognize whether a patient is under substantial mental stress. It is recommended that immediately after the implantation and before being discharged from hospital, a screening procedure for anxiety and depression should be carried out using, e.g. the Hospital Anxiety and Depression Scale (HADS) and to distribute a questionnaire on desired information and unanswered questions. This would not only give a lead in for a targeted consultation during the follow-up appointment in the first year but also allow the opportunity to offer such patients an education course in order to specifically approach the problem being experienced. Patients who have experienced more than 5 shocks in 12 months or more than 3 shocks in 1 episode should attend a psychocardiological consultation in order to check whether there are post-traumatic disorders. It is imperative that these be treated because they do not in general resolve spontaneously.

Nurse-lead clinics for capecitabine: A prospective audit evaluating changes in toxicity profile and efficacy

564

Background: Oral chemotherapy offers patients equal efficacy but fewer visits to hospital and less time spent traveling, but there are concerns about toxicity and compliance. Nursing and physician interactions with patients are different, and when a nurse-lead oral chemotherapy service was developed in NE Scotland in 2003 a prospective audit was begun to monitor safety and efficacy.

Methods: Patients with colorectal cancer who declined or were not eligible for appropriate clinical trials had their course of adjuvant or palliative capecitabine chemotherapy prospectively monitored through a nurse-lead clinic. At every clinic visit data was collected on patient demographics, blood and imaging results, and adverse events (AEs). Any decision to change dose was made by the colorectal oncology medical staff.

Results: From September 2003 to November 2006 there were 177 patients prospectively monitored through the nurse-lead clinics. Palliative patients (n = 100), median age 69 (range 43-89) and majority PS 0 or 1. Initial dose reduction in 30% due to low GFR and 13% due to being >75 years old. Overall 77% of patients completed on the starting dose. AE's, shown in table, and efficacy compared with capecitabine registration data (younger age group). Median overall survival 47.7 weeks (cf 56.6 weeks). Adjuvant patients (n = 77), median age 64 (range 40-88) and all PS 0 or 1. Initial dose reduction in 19% due to low GFR and 2% due to being >75 years old. Overall 58% completed on the starting dose (= X-ACT study). AEs, other than 5% G3/4 lethargy, and efficacy similar when compared with X-ACT data, including 3 year DFS of 64% (cf X-ACT 64%).

Conclusions: Using nurses to assess patients receiving capecitabine does not seem to significantly alter efficacy but does alter the AE profile compared with the registration data, particularly in the palliative patients. Differences in the nurse-patient relationship with nurses seen as less busy, more approachable and not taking treatment decisions can improve the quality of care in patients receiving capecitabine chemotherapy.

Management of physical health in patients with schizophrenia: international insights

This international meeting discussed the management of physical health in patients with schizophrenia in several countries including France, Spain, Germany, the UK and Italy. Physical health parameters, including weight, blood pressure, blood glucose, lipids and standard biochemical assessments are measured in many patients at the first hospital consultation. These reveal physical disorders such as obesity, hypertension, dyslipidaemia, the metabolic syndrome, substance abuse, cardiovascular disease, extrapyramidal symptoms, sexual dysfunction and diabetes in substantial proportions of patients. Psychiatrists consider switching antipsychotic therapy if excessive sedation, extrapyramidal symptoms, unacceptable weight gain, hyperglycaemia or dyslipidaemia occur. In general, switching is more likely to be considered for symptomatic adverse events than for laboratory abnormalities. Switching is discouraged by limited knowledge of protocols, the absence of guidelines and fears of relapse or reduced treatment adherence. The physical health of patients with schizophrenia receives much less attention in the community setting than in the hospital setting. Improved guidelines, protocols, resources and support are needed to improve the physical health of patients in the community.

Adeno-associated virus-mediated correction of a canine model of glycogen storage disease type Ia

Glycogen storage disease type Ia (GSDIa; von Gierke disease; MIM 232200) is caused by a deficiency in glucose-6-phosphatase-alpha. Patients with GSDIa are unable to maintain glucose homeostasis and suffer from severe hypoglycemia, hepatomegaly, hyperlipidemia, hyperuricemia, and lactic acidosis. The canine model of GSDIa is naturally occurring and recapitulates almost all aspects of the human form of disease. We investigated the potential of recombinant adeno-associated virus (rAAV) vector-based therapy to treat the canine model of GSDIa. After delivery of a therapeutic rAAV2/8 vector to a 1-day-old GSDIa dog, improvement was noted as early as 2 weeks posttreatment. Correction was transient, however, and by 2 months posttreatment the rAAV2/8-treated dog could no longer sustain normal blood glucose levels after 1 hr of fasting. The same animal was then dosed with a therapeutic rAAV2/1 vector delivered via the portal vein. Two months after rAAV2/1 dosing, both blood glucose and lactate levels were normal at 4 hr postfasting. With more prolonged fasting, the dog still maintained near-normal glucose concentrations, but lactate levels were elevated by 9 hr, indicating that partial correction was achieved. Dietary glucose supplementation was discontinued starting 1 month after rAAV2/1 delivery and the dog continues to thrive with minimal laboratory abnormalities at 23 months of age (18 months after rAAV2/1 treatment). These results demonstrate that delivery of rAAV vectors can mediate significant correction of the GSDIa phenotype and that gene transfer may be a promising alternative therapy for this disease and other genetic diseases of the liver.

European Guidelines for Quality Assurance in Cervical Cancer Screening. Second edition--summary document

European Guidelines for Quality Assurance in Cervical Cancer Screening have been initiated in the Europe Against Cancer Programme. The first edition established the principles of organised population-based screening and stimulated numerous pilot projects. The second multidisciplinary edition was published in 2008 and comprises ∼250 pages divided into seven chapters prepared by 48 authors and contributors. Considerable attention has been devoted to organised, population-based programme policies which minimise adverse effects and maximise benefits of screening. It is hoped that this expanded guidelines edition will have a greater impact on countries in which screening programmes are still lacking and in which opportunistic screening has been preferred in the past. Other methodological aspects such as future prospects of human papillomavirus testing and vaccination in cervical cancer control have also been examined in the second edition; recommendations for integration of the latter technologies into European guidelines are currently under development in a related project supported by the European Union Health Programme. An overview of the fundamental points and principles that should support any quality-assured screening programme and key performance indicators are presented here in a summary document of the second guidelines edition in order to make these principles and standards known to a wider scientific community.

Neurohumoral and metabolic response to exercise in water

Atrial natriuretic peptide (ANP) stimulates lipid mobilization and lipid oxidation in humans. The mechanism appears to promote lipid mobilization during exercise. We tested the hypothesis that water immersion augments exercise-induced ANP release and that the change in ANP availability is associated with increased lipid mobilization and lipid oxidation. In an open randomized and cross-over fashion we studied 17 men (age 31+/-3.6 years; body mass index 24+/-1.7 kg/m(2); body fat 17+/-6.7%) on no medication. Subjects underwent two incremental exercise tests on a bicycle ergometer. One test was conducted on land and the other test during immersion in water up to the xiphoid process. In a subset (n=7), we obtained electromyography recordings in the left leg. We monitored gas exchange, blood pressure, and heart rate. In addition, we obtained blood samples towards the end of each exercise step to determine ANP, norepinephrine, epinephrine, lactate, free fatty acids, insulin, and glucose concentrations. Heart rate, systolic blood pressure, and oxygen consumption at the anaerobic threshold and during peak exercise were similar on land and with exercise in water. The respiratory quotient was mildly reduced when subjects exercised in water. Glucose and lactate measurements were decreased whereas free fatty acid concentrations were increased with exercise in water. Water immersion attenuated epinephrine and norepinephrine and augmented ANP release during exercise. Even though water immersion blunts exercise-induced sympathoadrenal activation, lipid mobilization and lipid oxidation rate are maintained or even improved. The response may be explained by augmented ANP release.

Determinants of exercise-induced fat oxidation in obese women and men

Endurance training at an intensity eliciting maximal fat oxidation may have a beneficial effect on body weight and glucose metabolism in obese patients. However, the exercise intensity at which maximal fat oxidation occurs and the factors limiting fat oxidation are not well studied in this population. Obese, otherwise healthy men (n=38) and women (n=91) performed an incremental exercise test up to exhaustion on a cycle ergometer. Substrate oxidation was estimated using indirect calorimetry. Magnetic resonance tomography and spectroscopy were conducted to assess body fat distribution and intramyocellular fat content. We determined the exercise intensity at which maximal body fat oxidation occurs and assessed whether body composition, body fat distribution, intramyocellular fat content, or oxidative capacity predict exercise-induced fat oxidation. Maximal exercise-induced fat oxidation was 0.30+/-0.02 g/min in men and 0.23+/-0.01 g/min in women (p<0.05). Exercise intensity at the maximum fat oxidation was 42+/-2.2% VO (2 max) in men and 43+/-1.7% VO (2 max) in women. With multivariate analysis, exercise-induced fat oxidation was related to fat-free mass, percent fat mass, and oxidative capacity, but not to absolute fat mass, visceral fat, or intramyocellular fat content. We conclude that in obese subjects the capacity to oxidize fat during exercise appears to be limited by skeletal muscle mass and oxidative capacity rather than the availability of visceral or intramyocellular fat.
