Mortality risk of obesity and underweight is overestimated with self-reported body mass index.

Obese persons (those with a body mass index [BMI] ≥30 kg/m2) tend to underestimate their weight, leading to an underestimation of their true (measured) BMI and obesity prevalence.1,2 In contrast, underweight people (BMI <18.5 kg/m2) tend to report themselves heavier, resulting in a higher BMI compared with measured BMI and an underestimation of underweight prevalence.

Metabolic syndrome and the risk of breast cancer in postmenopausal women.

BACKGROUND: Only a few small studies investigated the association between postmenopausal breast cancer and metabolic syndrome (MetS) as a single entity. Materials and methods: We analyzed the data of two Italian and Swiss case-control studies conducted between 1983 and 2007, including 3869 postmenopausal women with incident breast cancer and 4082 postmenopausal controls admitted to the same hospitals as cases for acute conditions. MetS was defined as the presence of at least three components among diabetes, drug-treated hypertension, drug-treated hyperlipidemia, and obesity. RESULTS: The odds ratios (ORs) of postmenopausal breast cancer were 1.33 [95% confidence interval (CI) 1.09-1.62] for diabetes, 1.19 (95% CI 1.07-1.33) for hypertension, 1.08 (95% CI 0.95-1.22) for hyperlipidemia, 1.26 (95% CI 1.11-1.44) for body mass index ≥30 kg/m(2), and 1.22 (95% CI 1.09-1.36) for waist circumference ≥88 cm. The risk of postmenopausal breast cancer was significantly increased for women with MetS (OR = 1.75, 95% CI 1.37-2.22, for three or more MetS components, P for trend for increasing number of components < 0.0001) and the risk was higher at older age (OR = 3.04, 95% CI 1.75-5.29, at age ≥70 years for three or more MetS components). CONCLUSIONS: This study supports a direct association between MetS and postmenopausal breast cancer risk.

Reduction in the expression of glucose transporter protein GLUT 2 in preneoplastic and neoplastic hepatic lesions and reexpression of GLUT 1 in late stages of hepatocarcinogenesis.

Expression of two important glucose transporter proteins, GLUT 2 (which is the typical glucose transporter in hepatocytes of adult liver) and the erythroid/brain type glucose transporter GLUT 1 (representing the typical glucose transporter in fetal liver parenchyma), was studied immunocytochemically during hepatocarcinogenesis in rats at different time points between 7 and 65 wk after cessation of 7-wk administration of 12 mg/kg of body weight of N-nitrosomorpholine p.o. (stop model). Foci of altered hepatocytes excessively storing glycogen (GSF) and mixed cell foci (MCF) composed of both glycogenotic and glycogen-poor cells were present at all time points studied. Seven wk after withdrawal of the carcinogen, GSF were the predominant type of focus of altered hepatocytes. Morphometrical evaluation of the focal lesions revealed that the number and volume fraction of GSF increased steadily until Wk 65. MCF were rare at 7 wk, increased slightly in number and size until Wk 37, but showed a pronounced elevation in their number and volume fraction from Wk 37 to Wk 65. In both GSF and MCF, GLUT 2 was generally decreased or partially absent at all time points. Consequently, foci of decreased GLUT 2 expression showed a steady increase in number and volume fraction from Wk 7 to Wk 65. GLUT 1 was lacking in GSF but occurred in some MCF from Wk 50 onward. The liver type glucose transporter GLUT 2 was decreased in all adenomas and hepatocellular carcinomas (HCC). In three of seven adenomas and 10 of 12 carcinomas, expression of GLUT 1 was increased compared with normal liver parenchyma. In two cases of adenoid HCC, cells of ductular formations coexpressed GLUT 2 and GLUT 1. In contrast, normal bile ducts, bile duct proliferations, and cystic cholangiomas expressed only GLUT 1. Seven of 12 HCC contained many microvessels intensely stained for GLUT 1, a phenomenon never observed in normal liver. Whenever adenoid tumor formations occurred, GLUT 1-positive microvessels were located in the immediate vicinity of these formations. Only in one HCC were such microvessels found in the absence of adenoid formations. Our studies indicate that a reduction of GLUT 2 expression occurs already in early preneoplastic hepatic foci and is maintained throughout hepatocarcinogenesis, including benign and malignant neoplasms. Reexpression of GLUT 1, however, appears in a few MCF and in the majority of adenomas and carcinomas.

North South Survey of Children's Height, Weight and Body Mass Index, 2002

As part of a North South Survey of Childrens Oral Health conducted in Ireland in 2001/’02 [1], the heights and weights of a representative sample of children and adolescents age 4-16 years was measured. Data were collected by 34 teams of trained and calibrated dentists and dental nurses for 17,518 children aged 4-16 in the Republic of Ireland (RoI) and 2,099 in Northern Ireland (NI). This report presents the results of the study which provide a baseline measurement of Childrens height and weight against which future change can be measured. By comparing these data with international norms we can estimate the current prevalence of overweight and obesity among children and adolescents in Ireland.

Reproducibility and within-day variability of body fat measurements using segmental bipolar bioelectrical impedance in women

BACKGROUND AND AIMS: little is known regarding the reproducibility of body fat measuring devices; hence, we assessed the between and within-device reproducibility, and the within-day variability of body fat measurements. METHODS: body fat percentage was measured twice on seventeen female students aged between 18 and 20 with a body mass index of 21.9 ± 2.5 kg/m2 (mean ± SD) using seven bipolar bioelectrical impedance devices. Each participant was also measured each hour between 7:00 and 22:00. RESULTS: the correlation between first and second measurements was very high (Spearman r between 0.985 and 1.000, p<0.001), as well as between devices (Spearman r between 0.916 and 0.991, p<0.001). Repeated measurements analysis showed no differences were between devices (p=0.59) or readings (first vs. second: p=0.74). Conversely, significant differences were found between assessment periods throughout the day, measurements made in the morning being lower than those made in the afternoon (F test for repeated values= 6.58, p<0.001). CONCLUSIONS: the between and within-device reproducibility for measuring body fat is high, enabling the use of multiple devices in a single study. Conversely, small but significant changes in body fat measurements occur during the day, urging body fat measurements to be performed at fixed times.

PHA urges parents to get 'at risk' children vaccinated against seasonal flu

The Public Health Agency is urging Northern Ireland parents to make sure children in 'at risk' groups get their flu vaccine early.The message has been issued to parents and carers of children as the PHA's seasonal flu vaccination programme gets underway for 2011/12.It is very important that children with any condition that puts them more at risk of the complications of flu get the vaccine.These 'at risk' conditions include:chronic lung conditions such as asthma;chest infections that have required hospital admission;chronic heart conditions;chronic liver disease;chronic kidney disease;diabetes;lowered immunity due to disease or treatment such as steroids or cancer therapy;chronic neurological conditions such as stroke, multiple sclerosis or a condition that affects the nervous system, such as cerebral palsy;hereditary and degenerative diseases of the central nervous system or muscles.Children who attend special schools for severe learning or physical disabilities are considered to be particularly at risk, as well as those with other complex health needs.The PHA has written to principals of local special schools, as well as parents of children at these schools, to raise awareness of the importance of getting vaccinated early.Dr Richard Smithson, PHA Flu Vaccination Lead, said: "For many people, flu is a short, unpleasant illness, but it does not usually cause any serious problems. However, for others, it can have very serious complications including, in rare cases, being fatal."We have been particularly reminded over the last two winters that children with chronic neurological problems and other complex health needs are very vulnerable to these complications. We have seen children become very seriously ill and, tragically, there have even been a few deaths in children who attend special schools."For this reason, we recommend that all children who attend special schools for severe learning disability, and special schools for physical disability, are offered the flu vaccine early in the autumn, before the flu viruses start circulating."The vaccine is now available from GP surgeries and the PHA recommends that parents check arrangements with their own GP's surgery so that their child can get the jab.The earlier you get vaccinated the better, as it takes the body about 10-14 days after the jab to develop antibodies. These will then protect you against the same or similar viruses if the body is exposed to them. The vaccine contains three strains of the flu virus, which are considered the most likely to be circulating this winter, including the H1N1 (swine flu) virus."Your child needs to get the flu jab every year - the protection it gives only lasts for one winter, so even if they got it last year, they still need to get it this year," added Dr Smithson."Also, if your child has been diagnosed with flu or swine flu in the past couple of years, they will still need the jab this year as there are different types of flu that the jab will protect against. Getting the flu jab is the best way to protect your child against flu and we would strongly recommend that you arrange for them to have it."Although the vaccine gives good protection, no vaccine gives total protection, so if your child develops flu-like symptoms (such as fever, cough, aches and pains, and sore throat) you should contact your GP for advice. If your child has any of these symptoms, they should be kept at home until they feel better."For more information on seasonal flu, go to www.fluawareni.info and follow us on Facebook and Twitter.

A viscous bioerodible poly(ortho ester) as a new biomaterial for intraocular application.

The biocompatibility of a viscous, hydrophobic, bioerodible poly(ortho ester) (POE) intended for intraocular application was investigated. POE was evaluated as a blank carrier and as containing modulators of degradation. Each formulation was injected intracamerally and intravitreally in rabbit eyes, and clinical and histological examinations were performed postoperatively for 2 weeks. In the case of intracameral injections, polymer biocompatibility appeared to depend on the amount injected in the anterior chamber. When 50 microL was administered, the polymer degraded within 2 weeks, and clinical observations showed good biocompatibility of POE with no toxicity to the ocular tissues or increase in intraocular pressure. The injection of a larger volume, 100 microL, of POE, appeared inappropriate because of direct contact of polymeric material with the corneal endothelium, and triggered reversible edema and inflammation in the anterior chamber of the eye that regressed after a few days. After intravitreal administration, POE was well tolerated and no inflammatory reaction developed during the observation period. The polymer degraded slowly, appearing as a round whitish bubble in the vitreous cavity. The presence of modulators of degradation both improved POE biocompatibility and prolonged polymer lifetime in the eye. POE appears to be a promising biomaterial for clinical intraocular application.

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.

Geometry and physics of catenanes applied to the study of DNA replication.

The concept of ideal geometric configurations was recently applied to the classification and characterization of various knots. Different knots in their ideal form (i.e., the one requiring the shortest length of a constant-diameter tube to form a given knot) were shown to have an overall compactness proportional to the time-averaged compactness of thermally agitated knotted polymers forming corresponding knots. This was useful for predicting the relative speed of electrophoretic migration of different DNA knots. Here we characterize the ideal geometric configurations of catenanes (called links by mathematicians), i.e., closed curves in space that are topologically linked to each other. We demonstrate that the ideal configurations of different catenanes show interrelations very similar to those observed in the ideal configurations of knots. By analyzing literature data on electrophoretic separations of the torus-type of DNA catenanes with increasing complexity, we observed that their electrophoretic migration is roughly proportional to the overall compactness of ideal representations of the corresponding catenanes. This correlation does not apply, however, to electrophoretic migration of certain replication intermediates, believed up to now to represent the simplest torus-type catenanes. We propose, therefore, that freshly replicated circular DNA molecules, in addition to forming regular catenanes, may also form hemicatenanes.
