Get Healthwise this new year!

The Public Health Agency is encouraging people with specific health conditions to join the Healthwise scheme – a free 12 week physical activity programme to get their new year off to a healthy start. The scheme is available at registered leisure centres and Healthy Living Centres (HLCs) within the Belfast and South Eastern Health and Social Care Trust areas and is for people with certain health conditions who have been referred by their GP, nurse or other health professionals. The scheme is suitable for those with: • high blood pressure; • a body mass index (BMI) of more than 25; • asthma or chronic obstructive pulmonary disease (COPD); • diabetes; • osteoporosis; • hypertension; • coronary heart disease and associated risk factors; • anxiety; • stress; • depression.

Poots launches £18m state-of-the-art Telemonitoring NI service

Health Minister Edwin Poots today marked the roll-out of a ground-breaking hi-tech scheme which will enable more patients to monitor their health in their own homes. Following funding of £18m from the Department of Health, the newly named Centre for Connected Health and Social Care (CCHSC), part of the Public Health Agency, worked in partnership with business consortium TF3to establish the innovative Telemonitoring NI service. The service is now being delivered by the TF3 consortium in partnership with the Health and Social Care Trusts.Remote telemonitoring combines technology and services that enable patients with chronic diseases to test their vital signs such as pulse, blood pressure, body weight, temperature, blood glucose and oxygen levels at home on a daily basis. The service will now be rolled out to 3,500 patients across Northern Ireland per annum for a period of six years.Mr Poots today visited the home of Larne pensioner Michael Howard who has Chronic Pulmonary Obstructive Disorder (COPD) to hear how Telemonitoring NI has changed his life.During the visit Mr Poots said: "Chronic diseases such as heart disease, diabetes and COPD affect around three quarters of people over the age of 75. This is the generation from whom transport and mobility pose the biggest problems. The Telemonitoring NI service will allow thousands to monitor their vital signs without having to leave their own homes."It means that patients are able to understand and manage their condition better. Many say it has improved their confidence and given them peace of mind. With a health professional monitoring each patient's health on a daily basis, there is less need for hospital admission. Carers are also better informed with the pro-active support provided. It means earlier intervention in, and the prevention of, deterioration of condition, acute illness and hospital admissions."Telemonitoring NI is an excellent example of how the Health Service can innovateusing modern technology to deliver a better service for our patients."Eddie Ritson, Programme Director of CCHSC, PHA, said: "The roll-out of Telemonitoring NI represents a significant step towards providing quality care for the growing number of people with heart disease, stroke, some respiratory conditions and diabetes who want to live at home while having their conditions safely managed."This new service will give people more information which combined with timely advice will enable patients to gain more control over their health while supporting them to live independently in their own homes for longer."A patient will take their vital sign measurements at home, usually on a daily basis. and these will automatically be transmited to the Tf3 system. The resulting readings are monitored centrally by a healthcare professional working in the Tf3 triage team. If the patient's readings show signs of deterioration to an unacceptable level, they will be contacted by phone by a nurse working in a central team and if appropriate a healthcare professional in the patient's local Trust will be alerted to enable them to take appropriate action."Families and carers will also benefit from the reassurance that chronic health conditions are being closely monitored on an ongoing basis. The information collected through the service can also be used by doctors, nurses and patients in making decisions on how individual cases should be managed. "Using the service, Mr Howard, 71, who has emphysema - a long-term, progressive disease of the lungs that primarily causes shortness of breath - monitors his vital signs using the new technology every weekday morning. The information is monitored centrally and if readings show signs of deterioration to an unacceptable level, Mr Howard's local healthcare professional is alerted."Taking my readings is such a simple process but one that gives me huge benefits as it is an early warning system to me and also for the specialist nurses in charge of my care. Without the remote telemonitoring I would be running back and forward to the GPs' surgery all the time to have things checked out," he explained."Having my signs monitored by a nurse means any changes in my condition are dealt with immediately and this has prevented me from being admitted to hospital - in the past I've had to spend six days in hospital any time I'm admitted with a chest infection."The telemonitoring is not only reassuring for me, it also gives me more control over managing my own condition and as a result I have less upheaval in my life, and I'm less of a cost to the health care system. Most importantly, it gives me peace of mind and one less thing to worry about at my age."Patients seeking further information about the new telemonitoring service should contact their healthcare professional.

Twenty-four-hour energy expenditure in pregnant and nonpregnant Gambian women, measured in a whole-body indirect calorimeter.

Twenty-four-hour energy expenditure (EE), daily and sleeping EE, and the energy cost of a standardized treadmill exercise were assessed in a respiration chamber in 41 young pregnant Gambian women at 12 (n = 11), 24 (n = 15), and 36 (n = 15) wk of gestation and compared with 13 nonpregnant nonlactating (NPNL) control women. The rate of 24-h EE was significantly higher (P less than 0.001) at 36 wk gestation (8443 +/- 243 kJ/d) than in the NPNL group (6971 +/- 172 kJ/d) or at 12 and 24 wk (7088 +/- 222 and 7188 +/- 192 kJ/d, respectively). Per unit body weight, no more differences in 24-h EE, daily and sleeping EE, or energy cost of walking were observed between pregnant and NPNL women. There was no statistical difference in the 24-h respiratory quotient among the groups. We conclude that the state of pregnancy in Gambian women induces a progressive rise in 24-h EE, which becomes significant in the third trimester and is proportional to body weight.

Melanism, body condition and elevational distribution in the asp viper

Alternative morphotypes can confer important selective advantages in different habitats, whereas they can be penalized in other circumstances. In ectotherms, such as reptiles, the body colour can have direct effects on numerous aspects of their existence, such as thermoregulation or prey-predator interactions. Darker melanic individuals show lower skin reflectance and consequently heat up more rapidly and maintain optimal body temperatures more easily than lighter coloured individuals. As a consequence, melanistic individuals of diurnal species in cool areas may exhibit higher body condition, growth rate, survival and fecundity than lighter coloured individuals. Such advantages of dark coloration may be counterbalanced by a lower crypsis to predators and a decreased foraging efficiency. We investigated, in two montane populations of asp vipers Vipera aspis, the relationship between (1) colour polymorphism and body condition and length and (2) the coloration of individuals and their elevational distribution. We showed significant relationships between (1) the coloration, body condition and sex of individuals; (2) sexes and reproductive state and morph frequency; and (3) colour morphs that were distributed following an elevational gradient. Hence, colour polymorphism plays an important role in the ecology and evolution of the asp viper and is maintained through differential selective pressures.

Body Weight and Eating Habits in 5-12-Year Old Irish Children

A shared goal of safefood and the Health Service Executive (HSE) is to improve the health of the Irish population. One of the greatest public health threats facing all developed countries today, including the island of Ireland, is obesity. It is crucial that the various sectors and disciplines in the country work together to successfully deal with this growing issue. The Department of Health and Children (DoHC) published a strategy for obesity in 2005 which identified children and young people as a vulnerable, at-risk group. Both safefood and the HSE recognise the growing trend towards obesity, physical inactivity and unhealthy dietary habits in Ireland. Both organisations have been actively engaged in addressing the obesity epidemic. A number of initiatives targeted at school-aged children have already been established. These include the ‘Little Steps’ mass media campaign (www.littlesteps.eu) – a campaign aimed at supporting parents/guardians of children, as well as various school-based initiatives and relevant training programmes for health professionals.

Sex-specific selective pressures on body mass in the greater white-toothed shrew, Crocidura russula.

The direction, intensity and shape of viability-, sexual- and fecundity selection on body mass were investigated in a natural population of the greater white-toothed shrew (Crocidura russula), combining parentage assignment through molecular techniques and mark-recapture data over several generations. A highly significant stabilizing viability selection was found in both sexes, presumably stemming from the constraints imposed by their insectivorous habits and high metabolic costs. Sexual selection, directional in both sexes, was twice as large in males than in females. Our results suggest that body mass matters in this context by facilitating the acquisition and defense of a breeding territory. No fecundity selection could be detected. The direction of sexual size dimorphism (SSD) was in agreement with the observed pattern of selective pressures: males were heavier than females, because of stronger sexual selection. SSD intensity, however, was low compared with other mammals, because of the low level of polygyny, the active role of females in territory defense and the intensity of stabilizing viability selection.

Is lean body mass decreased after obesity treatment by adjustable gastric banding?

BACKGROUND: There is concern that surgically-induced weight loss in obese subjects is associated with a disproportionate decrease in lean body mass (LBM) and in skeletal muscle mass (SMM), a major constituent of LBM. To address this issue, 1) we measured total and regional body composition following gastric banding in a group of obese subjects, and 2) we compared these data to those of a non-surgical control group of similar age and body size. METHODS: Body composition was assessed by dual-energy X-ray absorptiometry (DEXA) before and after laparoscopic adjustable silicone gastric banding (LAGB) in 32 women (after 1 year: age 43.7+/-8.4 years, BMI 36.4+/-5.9 kg/m2, mean+/-SD), and in 117 control women (age 44.5+/-7.5 years; BMI 36.7+/-5.5 kg/m2) referred for non-surgical weight management, prior to weight loss. SMM was estimated using a published equation based on LBM of the extremities (appendicular LBM). RESULTS: 1 year after LAGB, body weight loss (-23.7+/-11.6 kg, P<10(-6)) was mainly due to decreased fat mass (-21.2+/-11.2 kg, P<10(-6)), and total LBM was modestly, although significantly, decreased (-2.1+/-4.2 kg, P=0.01). Appendicular LBM (-0.7+/-2.7 kg) and total SMM (-0.9+/-3.0 kg) were not significantly modified. None of the body composition variables was significantly decreased in weight-reduced subjects compared to the control group, especially appendicular LBM and total SMM. CONCLUSIONS: Results provide no evidence for a decrease in appendicular LBM and total SMM with weight loss following LAGB. Follow-up of these obese patients revealed a very favorable pattern of change in total and regional body composition, with preservation of muscle mass.

Body dissatisfaction on top of depressive mood among adolescents with severe dysmenorrhea.

OBJECTIVES: This study aims to determine whether adolescent girls with severe dysmenorrhea (SD) have different psychological characteristics from their peers. STUDY DESIGN: Cross-sectional survey (SMASH 02). SETTINGS: Nationally representative sample of adolescents attending post-mandatory education. PARTICIPANTS: N = 7548, of whom 3340 were females, aged 16-20 years. INTERVENTION: Self-administered, anonymous survey consisted of 565 items on 4 main topics: sociodemographic determinants of health, health status, health behaviors, and health care use. OUTCOMES: Body image variables, mental health, and associated variables like sexual abuse and health perceptions. Bivariate analysis and binomial logistic regression controlling for explanatory variables were performed. RESULTS: 12.4% (95% confidence interval [CI]: 11.0-14) declared SD. Compared to their peers, subjects with SD were more likely to report depressive symptoms (adjusted odds ratio [AOR]: 1.73; 95% CI: 1.38-2.15), have a higher gynecological age (AOR: 1.13; 95% CI: 1.05-1.20), and attend vocational school (AOR: 1.33; 95% CI: 1.00-1.76). Moreover, the proportion of those reporting dissatisfaction with their body appearance was higher (AOR: 1.50; 95% CI: 1.02-2.22). CONCLUSION: Patients with SD not only show a different profile from their peers in terms of their mental health academic track and gynecological age, but they are also more dissatisfied with their body appearance. Clinicians should pay particular attention to patients with SD and offer them a global evaluation, bearing in mind what factors can be associated with SD.

Body temperature regulation and outcome after cardiac arrest and therapeutic hypothermia.

OBJECTIVE: Therapeutic temperature modulation is recommended after cardiac arrest (CA). However, body temperature (BT) regulation has not been extensively studied in this setting. We investigated BT variation in CA patients treated with therapeutic hypothermia (TH) and analyzed its impact on outcome. METHODS: A prospective cohort of comatose CA patients treated with TH (32-34°C, 24h) at the medical/surgical intensive care unit of the Lausanne University Hospital was studied. Spontaneous BT was recorded on hospital admission. The following variables were measured during and after TH: time to target temperature (TTT=time from hospital admission to induced BT target <34°C), cooling rate (spontaneous BT-induced BT target/TTT) and time of passive rewarming to normothermia. Associations of spontaneous and induced BT with in-hospital mortality were examined. RESULTS: A total of 177 patients (median age 61 years; median time to ROSC 25 min) were studied. Non-survivors (N=90, 51%) had lower spontaneous admission BT than survivors (median 34.5 [interquartile range 33.7-35.9]°C vs. 35.1 [34.4-35.8]°C, p=0.04). Accordingly, time to target temperature was shorter among non-survivors (200 [25-363]min vs. 270 [158-375]min, p=0.03); however, when adjusting for admission BT, cooling rates were comparable between the two outcome groups (0.4 [0.2-0.5]°C/h vs. 0.3 [0.2-0.4]°C/h, p=0.65). Longer duration of passive rewarming (600 [464-744]min vs. 479 [360-600]min, p<0.001) was associated with mortality. CONCLUSIONS: Lower spontaneous admission BT and longer time of passive rewarming were associated with in-hospital mortality after CA and TH. Impaired thermoregulation may be an important physiologic determinant of post-resuscitation disease and CA prognosis. When assessing the benefit of early cooling on outcome, future trials should adjust for patient admission temperature and use the cooling rate rather than the time to target temperature.

Warm Front, Better Health: Health Impact Evaluation of the Warm Front Scheme

About 4 million households in the UK cannot adequately heat their homes in winter due to low income and poor quality housing, the two main causes of fuel poverty. The primary impact of fuel poverty is cold homes in winter which can lead to various health problems and even death among the vulnerable young and the elderly population. The government launched the Warm Front scheme in 2000 to tackle fuel poverty among the vulnerable households in England by providing energy efficiency measures in the forms insulation and modern heating system(??). By 2004, about 770,000 households had benefited from the Warm Front scheme and a total of 2 million households are still expected to benefit by 2010. Since 2001, the Bartlett has been investigating with London School of Hygiene & Tropical Medicine and Sheffield Hallam University, the health and the environmental impact of the Warm Front scheme. This investigative study is the most detailed to date on fuel poor dwellings based on detailed surveys of household and dwelling data, fuel consumption record and monitored temperature and relative humidity from 3,100 dwellings before and after the energy efficiency measures. The Warm Front investigation was expected to continue until the end of 2007. The findings from the investigation indicated that the Warm Front scheme was likely to have benefits in terms of improved thermal comfort and well-being as a result of mean temperature rise of 1.6C in the living room and 2.8C in the bedroom. Warm Front also lead to a decrease in indoor relative humidity mainly from the increased temperature since there appeared to be little impact on vapour pressure from changes in air tightness. Pressure test results indicated that the effects of air tightness measures such as draught stripping and cavity wall insulation were offset by the installation of a central heating system, particularly when the pipe work feeding radiators was installed below timber floors.

Binary classification of dyslipidemia from the waist-to-hip ratio and body mass index: a comparison of linear, logistic, and CART models.

BACKGROUND: We sought to improve upon previously published statistical modeling strategies for binary classification of dyslipidemia for general population screening purposes based on the waist-to-hip circumference ratio and body mass index anthropometric measurements. METHODS: Study subjects were participants in WHO-MONICA population-based surveys conducted in two Swiss regions. Outcome variables were based on the total serum cholesterol to high density lipoprotein cholesterol ratio. The other potential predictor variables were gender, age, current cigarette smoking, and hypertension. The models investigated were: (i) linear regression; (ii) logistic classification; (iii) regression trees; (iv) classification trees (iii and iv are collectively known as "CART"). Binary classification performance of the region-specific models was externally validated by classifying the subjects from the other region. RESULTS: Waist-to-hip circumference ratio and body mass index remained modest predictors of dyslipidemia. Correct classification rates for all models were 60-80%, with marked gender differences. Gender-specific models provided only small gains in classification. The external validations provided assurance about the stability of the models. CONCLUSIONS: There were no striking differences between either the algebraic (i, ii) vs. non-algebraic (iii, iv), or the regression (i, iii) vs. classification (ii, iv) modeling approaches. Anticipated advantages of the CART vs. simple additive linear and logistic models were less than expected in this particular application with a relatively small set of predictor variables. CART models may be more useful when considering main effects and interactions between larger sets of predictor variables.

Mechanisms of leukocyte lipid body formation and function in inflammation

An area of increasingly interest for the understanding of cell signaling are the spatio-temporal aspects of the different enzymes involved in lipid mediator generation (eicosanoid-forming enzymes, phospholipases and their regulatory kinases and phosphatases) and pools of lipid precursors. The compartmentalization of signaling components within discrete and dynamic sites in the cell is critical for specificity and efficiency of enzymatic reactions of phosphorilation, enzyme activation and function. We hypothesized that lipid bodies - inducible non-membrane bound cytoplasmic lipid domains - function as specialized intracellular sites of compartmentalization of signaling with major roles in lipid mediator formation within leukocytes engaged in inflammatory process. Over the past years substantial progresses have been made demonstrating that all enzymes involved in eicosanoid synthesis localize at lipid bodies and lipid bodies are distinct sites for eicosanoid generation. Here we will review our current knowledge on the mechanisms of formation and functions of lipid bodies pertinent to inflammation.
