    The interaction of ethanol with mercury in the body resulting in increased exhalation of the metal was studied in the mouse. A persistent elimination of the metal in the breath was demonstrated after single, sublethal (<1 mgHg/Kg body weight) exposures to mercury vapor (Hg/sup 0/) or mercury II chloride (HgCl/sub 2/). The amount of mercury exhaled per unit time was enhanced by oral or parenteral administration of ethanol solutions. These modifications were investigated in dose-response studies in which the drug was administered in doses ranging from 0.2g to 5.5g/Kg to mice pretreated with mercury. The EC/sub 50/ for blood ethanol with respect to mercury exhalation was determined to be approximately 200 mg/dl corresponding to an output rate of approximately 0.1% of the simultaneous body burden in 30 min several days after mercury. A hypothesis that mercury expired by these animals was proportional to the body burden after mercury administration was addressed in experiments whereby mice given one of several doses of mercuric chloride (0.16 to 500 ..mu..g/Kg) were monitored for pulmonary mercury elimination for a fifteen day period. The high correlation obtained between the amount of mercury exhaled in a standard time period and the body burden by group indicated that breath sampling could be applied as an indicator of the mercury body burden which may not be limited to the mouse.

  3. On the Estimation of a Systemic Body Burden of Plutonium

    International Nuclear Information System (INIS)

    Several computer programmes have been described in the literature which use the complete urinalysis record of employees to estimate their systemic body burden of plutonium 239, i.e. the body burden exclusive of plutonium 239 in the lungs or in the contents of the gastro-intestinal tract. For each successive sample date such codes use an excretion model, suggested by Langham, to estimate the urinary excretion that would be expected to result from prior intakes that have been estimated. Any excess in the sample is considered to indicate an additional intake, or is rejected as being the result of an erroneous determination. An examination of excretion data taken under controlled conditions indicates that there is considerable fluctuation about the smoothed curves used in the excretion model, that the deviations are by less than a factor of two in the majority of cases, and that much of this fluctuation must be accepted as of biological origin and not merely the result of faulty sampling techniques. This suggests that a mathematical treatment should accept small fluctuations as not necessarily indicating additional exposure or artifacts of sampling. Such a computer code has been written and tested on the few cases where the body burden is considered to be well established. These cases suggest that this technique may be an improvement over earlier methods. The code uses one index as specifying a level below which data are not considered to be significant, and a second index specifies the degree of excess over the general trend which is considered to be due to additional intake to blood.

  4. Evaluation of modelling body burden of Cs-137

    International Nuclear Information System (INIS)

    Within the IAEA/CEC VAMP-program one working group studied the precision in dose assessment models when calculating body burden of 137Cs as a result of exposure through multiple exposure pathways. One scenario used data from southern Finland regarding contamination of various media due to the fallout from the Chernobyl accident. In this study, a time dependent multiple exposure pathway model was constructed based on compartment theory. Uncertainties in model responses due to uncertainties in input parameter values were studied. The initial predictions for body burden were good, within a factor of 2 of the observed, while the time dynamics of levels in milk and meat did not agree satisfactorily. Some results, nevertheless, showed good agreement with observations due to compensatory effects. After disclosure of additional observational data, major reasons for mispredictions were identified as lack of consideration of time dependence of fixation of 137Cs in soils, and the selection of parameter values. When correction of this was made, a close agreement between predictions and observations was obtained. This study shows that the dose contribution due to 137Cs in food products from the seminatural environment is important for long-term exposure to man. The evaluation provided a basis for improvements of crucial parts in the model. 14 refs, 18 figs, 8 tabs

    Tissue heavy metal concentrations in painted (Chrysemys picta) and snapping (Chelydra serpentina) turtles from Lake Michigan coastal wetlands were analyzed to determine (1) whether turtles accumulated heavy metals, (2) if tissue metal concentrations were related to environmental metal concentrations, and (3) the potential for non-lethal sampling techniques to be used for monitoring heavy metal body burdens in freshwater turtles. Muscle, liver, shell, and claw samples were collected from painted and snapping turtles and analyzed for cadmium, chromium, copper, iron, lead, magnesium, manganese, and zinc. Turtle tissues had measurable quantities of all eight metals analyzed. Statistically significant correlations between tissue metal concentrations and sediment metal concentrations were found for a subset of metals. Metals were generally found in higher concentrations in the larger snapping turtles than in painted turtles. In addition, non-lethal samples of shell and claw were found to be possible alternatives to lethal liver and muscle samples for some metals. Human consumption of snapping turtles presents potential health risks if turtles are harvested from contaminated areas. Overall, our results suggest that turtles could be a valuable component of contaminant monitoring programs for wetland ecosystems.

    We aim to establish a new way for estimating the risk from internal dose or body burden due to exposure of benzene in human subject utilizing physiologically based pharmacokinetic (PBPK) model. We also intend to verify its applicability on human subjects exposed to different levels of benzene. We estimated personal inhalation exposure of benzene for two occupational groups namely petrol pump workers and car drivers with respect to a control group, only environmentally exposed. Benzene in personal air was pre-concentrated on charcoal followed by chemical desorption and analysis by gas chromatography equipped with flame ionization detector (GC-FID). We selected urinary trans,trans-muconic acid (t,t-MA) as biomarker of benzene exposure and measured its concentration using solid phase extraction followed by high performance liquid chromatography (HPLC). Our estimated inhalation exposure of benzene was 137.5, 97.9 and 38.7 μg/m(3) for petrol pump workers, car drivers and environmentally exposed control groups respectively which resulted in urinary t,t-MA levels of 145.4±55.3, 112.6±63.5 and 60.0±34.9 μg g(-1) of creatinine, for the groups in the same order. We deduced a derivation for estimation of body burden from urinary metabolite concentration using PBPK model. Estimation of the internal dose or body burden of benzene in human subject has been made for the first time by the measurement of t,t-MA as a urinary metabolite using physiologically based pharmacokinetic (PBPK) model as a tool. The weight adjusted total body burden of benzene was estimated to be 17.6, 11.1 and 5.0 μg kg(-1) of body weight for petrol pump workers, drivers and the environmentally exposed control group, respectively using this method. We computed the carcinogenic risk using both the estimated internal benzene body burden and external exposure values using conventional method. Our study result shows that internal dose or body burden is not proportional to level of exposure rather have a

  10. Chromosome breakage in lymphocytes from humans with body burdens of 226Ra

    International Nuclear Information System (INIS)

    Peripheral lymphocytes from 10 controls and 40 patients with body burdens of 226Ra ranging from below the limit of detection to 8.6 μCi were scored for unstable chromosome aberrations. The patient population was divided into four groups: a group with body burdens below the limit of detection (less than 0.003 μCi, 12 patients); a low-burden group (0.003 to 0.099 μCi, 13 patients); a moderate-burden group (0.1 to 0.99 μCi, 11 patients); and a high-burden group (greater than 1.0 μCi, 4 patients). In none of these groups was the frequency of cells with unstable aberrations significantly elevated above that in the controls. The rate of occurrence of dicentric and ring chromosomes was above the control frequency in only the two patients with the highest burdens (3.55 and 8.6 μCi). Our results are consistent with the expectation derived from a recent calculation of alpha dose delivered to blood by bone-deposited radium and its decay products. Marshall and Hoegerman have estimated that the blood dose for an individual with a radium burden of 1.0 μCi is 0.09 +- 0.03 rad/year. The value is compared with the dose estimate used by Boyd et al. in their study of British radium-dial painters, and the relevance of the blood dose to the lymphocyte dose is discussed

    Blue-winged Teal were collected before and after their migration to wintering grounds in Latin America. Pesticide burdens, body weights, and lipid levels of carcasses were determined. Only DDE and dieldrin were detected in a small proportion of the samples and then at concentrations far below known-effect levels. Residue loads, because of their infrequency, were not significantly correlated with overall body weight and percent lipid. Body weights among most age and sex classes did not differ in either fall or spring, nor did percent lipid in any instance. However, body weights and lipid levels were significantly correlated; as body weight increased so did percent lipid. Thus, the extreme variability in body weight appears to be a function of the amount of fat present and not overall body size, age, or sex.

  12. Bioassay program: determination of I-131 body burden among radiation workers and nuclear medicine laboratory technicians

    Energy Technology Data Exchange (ETDEWEB)

    Duran, E.B.; Napenas, D.; San Jose, V.; Juan, N.

    The body burden of I-131 was determined among the radiation workers of the Philippine Atomic Energy Commission (PAEC) who are directly involved in I-131 processing and nuclear laboratory technicians of University of Santo Tomas and Veterans Hospital, who handle and dispense I-131 to patients. The routine monitoring was done by urine analysis. The untreated urine samples were counted directly for 4000 seconds using Nal(Tl) scintillation detector coupled to an ND66 microcomputer-based multichannel analyzer. Urine samples of radiation workers of PAEC who are not involved in I-131 processing and non-radiation workers were also assayed for comparison. For radiation workers of PAEC who are directly involved in processing I-131, the estimated body burden of I-131 ranged from <0.055 to 8.53 uCi (282 urine samples). These values were higher than those observed for radiation workers not involved in the handling or processing of I-131 with estimated body burden of I-131 ranging from <0.055 to 0.52 uCi (48 urine samples) or than those observed from non-radiation workers (<0.055 uCi). The maximum permissible burden of I-131 is 0.7 uCi.

  13. Evaluation of radium-226 body burden by in vivo measurement of bismuth-214

    International Nuclear Information System (INIS)

    An indirect method of estimation of radium-226 body burden has been developed to overcome the difficulties of direct measurement of radium on account of low emission of 186 KeV gamma radiation that too in a region where the background count rate is high. The method is based on in vivo measurement of sup(214)Bi content of the body by a shadow shield whole body counter [102 mm (dia) x 76 mm (thick) NaI(Tl) detector]. sup(214)Bi emits gamma rays of 0.609, 1.120 and 1.764 MeV of which the last one is suitable for whole body counting because in that energy region there is no contribution from naturally occurring radioisotopes in the body (e.g. sup(40)K) and the response is independent of variation in body build. The ratio of the minimum detectable radium body burden for the whole body monitor at Jaduguda uranium mines using the indirect and direct methods for the same counting periods works out to be 0.85, indicating that the indirect method is somewhat superior to the direct method.

    1985-04-01

    Hexachlorobenzene (HCB), a ubiquitous lipophilic pollutant, was readily transferred in the milk of lactating dams to their suckling neonates. Pregnant CD-1 mice were treated during gestation, and the body burdens of HCB in the neonates and the dams were determined during lactation. Also, neonates from dams treated with HCB during gestation were cross-fostered at birth to dams treated with corn oil during gestation. The body burdens of HCB were greater in the neonates exposed to HCB by lactational transfer than the neonates exposed only by gestational transfer. In many tissues, the concentration of HCB in the pups from full litter was similar to that in pups from litters reduced to two pups per litter. Lactational transfer of HCB from the dams to the pups was a major route of excretion in that 95% of HCB was depleted during 20 days of lactation. HCB depletion was similar in dams with whole litters, and those with litters reduced to two pups.

  15. Physiological Properties of Plutonium and Assessment of Body Burden in Man

    International Nuclear Information System (INIS)

    Twenty years have elapsed since enough plutonium became available to create a potential industrial health problem. Subsequent human experience and animal experimentation show that, of the three principal modes of exposure (inhalation, ingestion and skin absorption), inhalation is the most important. Deposition, elimination, absorption and tissue distribution of inspired plutonium are strongly dependent on chemical form, particle size, exposure procedure and animal species, resulting in quantitative exceptions to any generalized model as to disposition and fate of inhaled plutonium. Exposure via ingestion is of little Importance; gut absorption Is about 0.002%/h of the ingested dose. Absorption through unbroken skin is less than 0.0002% of contact. Contaminated wounds (second only to inhalation as a potential industrial medical problem) result in slow absorption into the circulation, contributing to a systemic burden and producing chronic radiation changes at the site of implant. Tissue distribution of plutonium is dependent on mode of exposure, chemical form, particle size and colloidal aggregation. Presently the only routine method of assessing plutonium body burden is to relate urinary excretion to body burden through the expression D = 435 Ut-0.76, where D is body burden, U is daily output in urine, both in the same units, and t is time (in days) following exposure. This empirical relationship was established in a limited number of terminal human subjects following a single intravenous injection of a small amount of Pu+4-citrate. Two computer methods have been developed to relate excretion rate under chronic exposure conditions to body burden on the basis of the above expression. Validity of these methods has not been proven. Although improved methods of urine analysis have been developed, no improvement in the basic expression or its applicability to exposure conditions more closely approaching those encountered in practice has been produced. No procedure

    Full Text Available PURPOSE: Patients with neurofibromatosis 1 (NF1, NF2, and schwannomatosis are at risk for multiple nerve sheath tumors and premature mortality. Traditional magnetic resonance imaging (MRI has limited ability to assess disease burden accurately. The aim of this study was to establish an international cohort of patients with quantified whole-body internal tumor burden and to correlate tumor burden with clinical features of disease. METHODS: We determined the number, volume, and distribution of internal nerve sheath tumors in patients using whole-body MRI (WBMRI and three-dimensional computerized volumetry. We quantified the distribution of tumor volume across body regions and used unsupervised cluster analysis to group patients based on tumor distribution. We correlated the presence and volume of internal tumors with disease-related and demographic factors. RESULTS: WBMRI identified 1286 tumors in 145/247 patients (59%. Schwannomatosis patients had the highest prevalence of tumors (P = 0.03, but NF1 patients had the highest median tumor volume (P = 0.02. Tumor volume was unevenly distributed across body regions with overrepresentation of the head/neck and pelvis. Risk factors for internal nerve sheath tumors included decreasing numbers of café-au-lait macules in NF1 patients (P = 0.003 and history of skeletal abnormalities in NF2 patients (P = 0.09. Risk factors for higher tumor volume included female gender (P = 0.05 and increasing subcutaneous neurofibromas (P = 0.03 in NF1 patients, absence of cutaneous schwannomas in NF2 patients (P = 0.06, and increasing age in schwannomatosis patients (p = 0.10. CONCLUSION: WBMRI provides a comprehensive phenotype of neurofibromatosis patients, identifies distinct anatomic subgroups, and provides the basis for investigating molecular biomarkers that correlate with unique disease manifestations.

    Petroleum seep mussels are often exposed to high hydrocarbon concentrations in their natural habitat and, thus, offer the opportunity to examine the relationship between parasitism, disease and contaminant exposure under natural conditions. This is the first report on the histopathology of cold-seep mussels. Seep mussels were collected by submersible from four primary sites in the Gulf of Mexico, lease blocks Green Canyon (GC) 184, GC-234, GC-233, and Garden Banks 425 in 550-650 m water depth. Five types of parasites were identified in section: (1) gill "rosettes" of unknown affinity associated with the gill bacteriocytes, (2) gill "inclusions" similar to chlamydia/rickettsia inclusions, (3) extracellular gill ciliates, (4) body "inclusions" that also resemble chlamydial/rickettsial inclusions, and (5) Bucephalus-like trematodes. Comparison to shallow-water mytilids demonstrates that: (1) both have similar parasite faunas; (2) seep mytilids are relatively heavily parasitized; and (3) infection intensities are extremely high in comparison to shallow-water mytilids for Bucephalus and chlamydia/rickettsia. In this study, the lowest prevalence for chlamydia/rickettsia was 67%. Prevalences of 100% were recorded from three populations. Bucephalus prevalence was ⩾70% in three of 10 populations. The parasite fauna was highly variable between populations. Some important parasites were not observed in some primary sites. Even within primary sites, some important parasites were not observed in some populations. Bucephalus may exert a significant influence on seep mussel population dynamics. Forty percent of the populations in this study are severely reproductively compromised by Bucephalus infection. Only a fraction of petroleum seep mussel populations are maintaining the entire beta-level population structure of this species. Variation in two parasites, gill ciliates and Bucephalus, explained most of the variation in PAH body burden between mussel populations. PAHs are

    Full Text Available Hg is an accumulative and neuro-toxic heavy metal which has a wide range of adverse effects in human health. However, few studies are available on body burden of Hg level in different bio-samples of pregnant women in Chinese population. Therefore, this study evaluated Hg levels in different maternal bio-samples in Shenyang city, China and investigated the correlation of Hg levels in different bio-samples. From October to December 2008, 200 pregnant women about to deliver their babies at ShengJing Hospital (Shenyang city, northeast of China participated in this study. The geometric mean (GM of Hg levels in cord blood, maternal venous blood, breast milk, and maternal urine were 2.18 µg/L, 1.17 µg/L, 1.14 µg/L, and 0.73 µg/L, respectively, and the GM of maternal hair Hg level was 404.45 µg/kg. There was a strong correlation between cord blood and maternal blood total Hg level (r = 0.713, P<0.001. Frequency of fish consumption more than or equal to 3 times per week during pregnancy was suggested as a significant risk factor of prenatal Hg exposure (unadjusted OR 3.5, adjusted OR 2.94, P<0.05. This study provides evidence about Hg burden of mothers and the risk factors of prenatal Hg exposure in Shenyang city, China.

  19. Determination of Plutonium Body Burdens from Measurements of Daily Urine Excretion

    International Nuclear Information System (INIS)

    The original data from 16 human experiments, as reported by Wright Langham and others, have been reanalysed using a simple compartment model. The functions obtained from this analysis, relating the body burden to the daily excretion in urine following an injection, are used in proposed mathematical models for the slow release of soluble plutonium into the blood stream from a wound site or the lungs. The results of calculations on the model for various hold-up times at the wound site or lungs are presented graphically. The presently available data on the biological variation between men and in the day-to-day plutonium in urine excretion in an individual are analysed and discussed with special reference to the best design of a routine urine sampling programme.

  20. The economic consequences of elevated body-lead burdens in urban children

    International Nuclear Information System (INIS)

    The following analysis develops the theory and implementation of the observed behavior technique in an altruistic setting, to assess the health benefits of reducing environmental lead exposure in urban children. Three models are presented which allow for endogenous body lead burden, risk of irreversible neurological damages, and Bayesian information. Conditions are derived under which the observed behavior technique can be modified to value the health consequences of exposure to a general class of persistent micropollutants (PMP's): the heavy metals. Benefit expressions reflect the tradeoff between parental wealth and child health when children are exposed to low level doses of lead. The purpose is to derive exact measures of marginal welfare change associated with variations in child body lead burden, and to determine the conditions under which these measures will be functions of observable parameters. The analysis presents an entirely ex ante approach to the recovery of benefit estimates when PMP exposure involves risk of irreversible health damages. In doing so, an empirical estimate is also obtained for the parental value of child health information that is used in the revision of prior risk beliefs. Risk of chronic irreversible health effects in younger generations from environmental lead exposure may be experienced by a large share of metropolitan population in the US. Given the large numbers of possible victims, the aggregate social value of avoiding this risk is an important policy issues. Moreover, the value of health risk information is potentially important to the use of an information program as a policy instrument in reducing health risk because it would enable the comparison of societal benefits from an information program to the cost of it's implementation

  1. The Severity of Autism Is Associated with Toxic Metal Body Burden and Red Blood Cell Glutathione Levels

    International Nuclear Information System (INIS)

    This study investigated the relationship of children's autism symptoms with their toxic metal body burden and red blood cell (RBC) glutathione levels. In children ages 38 years, the severity of autism was assessed using four tools: ADOS, PDD-BI, ATEC, and SAS. Toxic metal body burden was assessed by measuring urinary excretion of toxic metals, both before and after oral dimercaptosuccinic acid (DMSA). Multiple positive correlations were found between the severity of autism and the urinary excretion of toxic metals. Variations in the severity of autism measurements could be explained, in part, by regression analyses of urinary excretion of toxic metals before and after DMSA and the level of RBC glutathione (adjusted R2 of 0.220.45, P<.005 in all cases). This study demonstrates a significant positive association between the severity of autism and the relative body burden of toxic metals.

    The purpose of this study is to apply an age-dependent half life model to examine the range of child (ages 0-7) body burdens that correspond to selected exposure scenarios involving background dietary and environmental doses of dioxins. The scenarios examined include breast-fed and nonbreast- fed infants feeding for 6 months, other dioxin uptake from foods through age 7, and exposures to urban residential soils at 1 ppb TCDD toxic equivalents (TEQ). These body burden estimates in children are then compared to the adult body burden estimates corresponding to the range of tolerable daily intakes (1 to 4 pg TEQ/kg-day) proposed by some U.S. and international regulatory/advisory groups.

  3. Body burden of cadmium and its related factors: A large-scale survey in China

    International Nuclear Information System (INIS)

    A survey of more than 6000 participants from four distinct non-polluted and polluted regions in China was conducted to evaluate the body burden of cadmium (Cd) on the Chinese populations using urinary Cd (UCd) as a biomarker. The findings revealed that the UCd level was 1.24 μg/g creatinine (μg/g cr) for the sample population from non-polluted Shanghai, and the UCd levels exceeded 5 μg/g cr, which is the health-based exposure limit set by the World Health Organization (WHO), in 1.1% of people. The mean UCd levels in moderately polluted (Hubei and Liaoning) and highly polluted areas (Guizhou) were 4.69 μg/g cr, 3.62 μg/g cr and 6.08 μg/g cr, respectively, and these levels were 2.9 to 4.9 times the levels observed in Shanghai. Notably, the UCd levels exceeded the recently updated human biomonitoring II values (i.e., intervention or “action level”) in 44.8%–87.9% of people from these areas compared to only 5.1%–21.4% of people in Shanghai. The corresponding prevalence of elevated UCd levels (> WHO threshold, 5 μg/g cr) was also significantly higher (30.7% to 63.8% vs. 1.1%), which indicates that elevated Cd-induced health risks to residents in these areas. Age and region were significant determinants for UCd levels in a population, whereas gender did not significantly influence UCd. - Highlights: • We performed a Cd exposure survey that involved more than 6000 Chinese subjects. • The body burden of Cd in most of subjects of non-polluted Shanghai is relatively safe. • The UCd levels were much higher in the subjects from polluted areas than from Shanghai. • The UCd levels in the population from Guizhou substantially exceeded the safety limit. • Age and region were significant determinants of UCd

    Despite the increasing awareness of arsenic (As) contamination in surface waters worldwide, little is known about how As alone and in the presence of other chemicals affects aquatic insects. Larvae of Chironomus riparius were exposed in a laboratory investigation to factorial combinations of 0, 0.13, 2.0, 5.3, and 13 {mu}mol As l{sup -1} and 0, 0.15, and 15 {mu}mol PO{sub 4} l{sup -1} throughout development from first instar to pupal emergence. The time between male and female emergence increased from 1.8 {+-} 0.17 days to 2.9 {+-} 0.34 days with exposure at higher As levels. The highest As exposure also decreased the number of eggs per egg mass, which may affect population maintenance. For these parameters, there was no effect from PO{sub 4}, and no interaction between As and PO{sub 4}. Total As determination of larval and adult tissues was conducted using Hydride Generated Atomic Absorption Spectroscopy (HGAAS) and revealed concentrations ranging from 2.48 {+-} 0.363 to 30.5 {+-} 0.473 {mu}g/g and 1.03 {+-} 0.286 to 8.97 {+-} 0.662 {mu}g/g, respectively, indicating elimination of approximately 72% of total As body burdens between the fourth instar and adult stages. There was no effect of PO{sub 4}, indicating PO{sub 4} does not alter uptake of As in C. riparius. The potential for movement of As to terrestrial systems exists, though trophic transfer may be more likely during the aquatic larval stage. - Highlights: Black-Right-Pointing-Pointer We evaluate how sublethal concentrations of As and P affect C. riparius. Black-Right-Pointing-Pointer High As exposure significantly increased the time between male and female emergence. Black-Right-Pointing-Pointer High As exposure significantly decreased the number of eggs per egg mass. Black-Right-Pointing-Pointer Fourth instar larvae eliminate 72% of As body burdens before the adult stage.

    To determine whether preexposure of green mussel Perna viridis to Ag influenced metal uptake kinetics we compared various physiological indicators of metal uptake kinetics between the control mussels and mussels preexposed to Ag in both diet and water at different levels (up to 5 weeks). In all preexposed mussels, the assimilation of Ag increased by 1.1-3.0 times with increasing Ag body concentration (0.651-19.3 microg g(-1)) as compared with the controls (Ag body concentration of 0.311-0.479 microg g(-1)), whereas the efflux rate constants decreased by 45-88%. There was no significant increase in Ag associated with the metallothionein-like protein (MTLP) fraction following exposure of the mussels to Ag through either the dissolved or food phase. The clearance rates were little affected or depressed byAg preexposure, and the relationship between the Ag influx rate from the dissolved phase and the Ag preexposure was somewhat complicated. The influx rate decreased with increasing Ag body burden at <2.5 microg g(-1), above which it increased with increasing Ag body burden. Our results indicate that the mussels may modify physiological processes to ambient chronic Ag exposure, consequently accumulating more Ag. Ag body concentration in these mussels may therefore increase disproportionally in response to increasing Ag concentration in the ambient environments. Ag preexposure and resulting body burden should be considered carefully when interpreting the observed Ag concentration in biomonitoring animals to evaluate the Ag pollution in seawater.

  8. Research With A View To Estimating The Body Burden Of Rare Earths On The Basis Of Excreta Measurements

    International Nuclear Information System (INIS)

    Body burden can be estimated directly from excreta measurements only if the chemical nature of the element involved is the sole factor governing distribution and rates of exchange in the body. Many authors have already called attention to the way in which metabolism and elimination rates are affected by various parameters, such as the nature of the anionic radical, the valency of the element, the physico-chemical state of the contaminating form and the channel and manner of contamination. The authors show that these factors mainly affect the initial kinetics of distribution in the body during the very first minutes. Using high-speed recording techniques and varying several experimental parameters, they studied the effect of these parameters on initial kinetics, the subsequent evolution of contamination in the various tissues and elimination processes. In particular, they recorded the kinetics of bile and urine elimination, blood purification and the radioactivity level of various organs (liver, kidneys, lungs). In order to relate the body burden to the quantities of radioisotope eliminated, it is necessary to know the amounts present in the various compartments, their rates of exchange and the times required for elimination by the various channels. In an attempt to clarify these points, the authors devised a test using a chelating agent which modifies the equilibria between compartments and directs all available cerium towards the elimination channels. By comparing the elimination values measured before and during the test, they attempt to calculate the total body burden and its distribution. They also discuss ways of applying this test at various stages in contamination. (author)

    Radioactive131 iodine (RAI) body burden is estimated in thyroid cancer patients by a) exposure rate meter and b) external probe counting. A calibration factor of 301 cpm/MBq (d = 16 cm) is used for the probe for estimates of whole body activity. Patients sit in a rotating stool with their center corresponding to the field of view for estimation of whole body RAI. Radioactive counts are obtained for anterio posterior (AP) and postero anterior (PA) geometries. Whole body retention factor is expressed as a ratio against assayed activity administered to the patient on day 1. With exposure rate measurement, for off-thyroxin (hypothyriod) patients, the retention factors were 0.148 ± 0.12 (n = 211) and 0.07 ± 0.08 (n = 68) at 48 h and 72 h, respectively. For recombinant TSH (rhTSH) (euthyroid) group, the retention factors were 0.089 ± 0.06 (n = 24) and 0.05 ± 0.05 (n = 19) at 48 h and 72 h, respectively. By probe counting method, the obtained retention factors were 0.081 ± 0.013 (range: 0.071–0.096) (off-thyroxine group) and 0.039 ± 0.03 (range: 0.008–0.089) for the rhTSH group at 48 h. The 72 h retentions in the off thyroxine (hypothyriod) group and the rhTSH (euthyroid) group were 0.048 ± 0.024 (range: 0.016–0.076) and 0.005, respectively. The radioactive body burdens at 48 h were in the range of 290-315 MBq (7.8–8.5 mCi) for the off-thyroxine group and 44–286 MBq (1.2–7.7 mCi) for the rhTSH group. The calculated residence times in whole body were 21.97 ± 3.8 h (range: 17.1–27.1) for off-thyroxine group and 14.28 ± 2.75 h (range: 9.97-19.46) showing high statistical significance (P radioactive iodine. There was no correlation between administered activity and retained body burden at 48 h or 72 h. PMID:27651735

  10. An Assessment of the Intestinal Lumen as a Site for Intervention in Reducing Body Burdens of Organochlorine Compounds

    2013-01-01

    Full Text Available Many individuals maintain a persistent body burden of organochlorine compounds (OCs as well as other lipophilic compounds, largely as a result of airborne and dietary exposures. Ingested OCs are typically absorbed from the small intestine along with dietary lipids. Once in the body, stored OCs can mobilize from adipose tissue storage sites and, along with circulating OCs, are delivered into the small intestine via hepatic processing and biliary transport. Retained OCs are also transported into both the large and small intestinal lumen via non-biliary mechanisms involving both secretion and desquamation from enterocytes. OCs and some other toxicants can be reabsorbed from the intestine, however, they take part in enterohepatic circulation(EHC. While dietary fat facilitates the absorption of OCs from the small intestine, it has little effect on OCs within the large intestine. Non-absorbable dietary fats and fat absorption inhibitors, however, can reduce the re-absorption of OCs and other lipophiles involved in EHC and may enhance the secretion of these compounds into the large intestine—thereby hastening their elimination. Clinical studies are currently underway to determine the efficacy of using non-absorbable fats and inhibitors of fat absorption in facilitating the elimination of persistent body burdens of OCs and other lipophilic human contaminants.

    Patients with neurofibromatosis 1 (NF1), NF2, and schwannomatosis share a predisposition to develop multiple nerve sheath tumors. Previous studies have demonstrated that patients with NF1 and NF2 have reduced quality of life (QOL), but no studies have examined the relationship between whole-body tumor burden and QOL in these patients. We administered a QOL questionnaire (the SF-36) and a visual analog pain scale (VAS) to a previously described cohort of adult neurofibromatosis patients undergoing whole-body MRI. One-sample t-tests were used to compare norm-based SF-36 scores to weighted population means. Spearman correlation coefficients and multiple linear regression analyses controlling for demographic and disease-specific clinical variable were used to relate whole-body tumor volume to QOL scales. Two hundred forty-five patients (142 NF1, 53 NF2, 50 schwannomatosis) completed the study. Subjects showed deficits in selected subscales of the SF-36 compared to adjusted general population means. In bivariate analysis, increased tumor volume was significantly associated with pain in schwannomatosis patients, as measured by the SF-36 bodily pain subscale (rho = -0.287, P = 0.04) and VAS (rho = 0.34, P = 0.02). Regression models for NF2 patients showed a positive relationship between tumor burden and increased pain, as measured by the SF-36 (P = 0.008). Patients with NF1, NF2, and schwannomatosis suffer from reduced QOL, although only pain shows a clear relationship to patient's overall tumor burden. These findings suggest that internal tumor volume is not a primary contributor to QOL and emphasize the need for comprehensive treatment approaches that go beyond tumor-focused therapies such as surgery by including psychosocial interventions.

    International Nuclear Information System (INIS)

    This Symposium on the Assessment of Radioactive Body Burdens in Man was organized jointly by the International Atomic Energy Agency, the International Labour Organisation and the World Health Organization and was held in Heidelberg from 11-15 May 1964. It was attended by 181 participants from 28 countries and 6 international organizations. It was the objective of the Symposium to bring together experts from the various scientific disciplines of physics, chemistry, biology, medicine and mathematics, and to survey their experience in the assessment of radioactive body burdens in man and the resultant radiation doses. In most investigations of internal contamination the errors in the physical measurements are smaller than the errors associated with the interpretation of measurements. For this reason special emphasis was laid in this meeting on the interpretation of measured data. The 67 papers and the discussions which they stimulated are published in these Proceedings produced in two volumes. Volume I includes all papers which deal with problems generally common to many isotopes: in- vivo counting, bioassay techniques, sample counting and analysis of data. Volume II includes those papers concerned with radioisotopes of specific elements: caesium, radium, radon, strontium, tritium, thorium, uranium, plutonium and rare earth elements. These Proceedings should prove invaluable to all radiation protection services entrusted with the physical surveillance of internal radiation exposure of man. They should complement the studies of the International Commission on Radiological Protection (ICRP) and assist the work of the Organizations that jointly organized the meeting

    International Nuclear Information System (INIS)

    Several groups of people living in Moscow were measured for fallout 137Cs in 1980-1983. In vivo measurements of incorporated 137Cs were made with use of a whole-body counter. The minimum measurable activities of 137Cs were 37 and 17 Bq consequently for time of measurement 15 and 30 min. All persons measured were classified into four groups, personnel of whole-body counters laboratory, teenagers-sportsman, patients of a Moscow hospital (with heart and kidneys diseases) and normal adults-inhabitants of Moscow. The activity of 137Cs in the normal adults and patients was observed to decrease during the period of investigation. It was shown that by the end of 1983 the great majority of the results were similar and below the minimum measurable activity (for time of measurement 15 min)

  17. The significance of hair mineral analysis as a means for assessing internal body burdens of environmental pollutants

    International Nuclear Information System (INIS)

    During a five-year period, the International Atomic Energy Agency supported a Coordinated Research Programme (CRP) to investigate the quantitative relationship between internal body burdens of a number of elements of environmental health significance and their respective concentrations in hair. The use of nuclear-related analytical techniques, such as neutron activation analysis, X-ray fluorescence, particle-induced X-ray emission and radiotracers, was emphasized. One aspect of the CRP focused on studies in man, using autopsy cases, of mineral distribution in five tissues, i.e. liver, kidney, lung, brain and bone in addition to hair, and the elements of primary importance were As, Cd, Cu, Hg, Pb, Se and Zn. Emphasis was placed on analytical quality assurance. Hair and internal tissue samples were obtained from subjects from Bulgaria, China, the former German Democratic Republic, Hungary, Japan, Norway and Sweden. (author) 4 refs.; 4 figs.; 3 tabs

  18. Hair as an indicator of the body burden of metals in relation to age

    International Nuclear Information System (INIS)

    Many factors influencing metal deposition in hair are still unknown. Animal experiments were performed to obtain data on the mechanism of transfer of elements into hair and to estimate whether hair retention is influenced by age, sex and chelating agent treatment. Experiments were performed on albino rats (Wistar strain) of different age and sex. Whole body hair (skin included) and organ retention of various elements was determined at different periods of time after intraperitoneal administration of the radioactive isotopes 115mCd, 203Hg, 54Mn, 59Fe, 65Zn, 141Ce, 137Cs, 203Pb and 85Sr. In some experiments DTPA was used for reducing body retention of 155mCd and 141Ce and DMPS for reducing 203Hg retention. Results show that hair and organ retention of elements in rats varies with age, sex and chelation treatment and such changes are specific for each element and can not be generalized. Age as a factor influencing hair retention of metals is likely to be more important for some elements than for others. In kinetic studies we found that due to differences in element distribution and kinetics, the relationship between hair and organ retention at various time intervals varies both with age and the element concerned. Sex influences not only hair but also metal retention and distribution in other organs. (author). 4 refs

  19. The significance of hair mineral analysis as a means for assessing internal body burdens of environmental pollutants

    International Nuclear Information System (INIS)

    In recent years there has been a considerable growth of interest in problems of environmental pollution from industrial and agricultural substances and the harmful impact of such pollution on human health. There has been an increasing interest in using hair mineral analysis for biological monitoring of human population exposure to environmental mineral pollutants. This is because hair has some ideal attributes for such purposes. It can be collected by simple, non-invasive methods, and is easily sampled and stored. Concentrations of most of the toxic trace elements, i.e. mercury and lead, in scalp hair are at least an order of magnitude higher than those in body fluids or other easily accessible tissues. In addition, mineral elements in hair can easily be determined with good precision and sensitivity by nuclear as well as conventional methods of chemical analysis. Despite these apparent advantages of using hair as a biomonitor, serious uncertainty existed, and to some extent still exist, as to the meaningful interpretation of human hair mineral data in environmental health studies. The Co-ordinated Research Programme (CRP), which is the subject of this report, has attempted to tackle this problem by promoting a variety of studies (as distinct from routine monitoring) to investigate the quantitative relationships between internal body burdens of a number of elements of environmental health significance and their respective concentrations in hair.

    Background Lower body-mass index (BMI) in late life has been associated with an increased risk of dementia, and weight loss has been associated with more rapid decline in Alzheimer disease (AD) dementia. Objective To explore the association between BMI and cortical amyloid burden in clinically normal (CN) elderly at risk for AD dementia. Methods Cross-sectional analyses were completed using baseline data from the Harvard Aging Brain Study, consisting of 280 community-dwelling CN older adults aged 62–90. Assessments included medical histories and physical exam, Pittsburgh compound B (PiB) positron emission tomography (PET) amyloid imaging, and apolipoprotein E ɛ4 (APOE4) genotyping. For the primary analysis, a general linear regression model was used to evaluate the association of BMI with PiB retention. Covariates included age, sex, years of education, and APOE4 carrier status. Secondary analyses were performed for BMI subdivisions (normal, overweight, obese), APOE4 carriers, and BMI × APOE4 interaction. Results In the primary analysis, greater PiB retention was associated with lower BMI (β=−0.14, p=0.02). In the secondary analyses, APOE4 carrier status (β=−0.27, p=0.02) and normal BMI (β=−0.25, p=0.01), as opposed to overweight or obese BMI, were associated with greater PiB retention. The BMI × APOE4 interaction was also significant (β=−0.14, p=0.04). Conclusions This finding offers new insight into the role of BMI at the preclinical stage of AD, wherein lower BMI late in life is associated with greater cortical amyloid burden. Future studies are needed to elucidate the mechanism behind this association, especially in those with lower BMI who are APOE4 carriers. PMID:27340843

    As part of NOAA's Status and Trends Program, oysters were sampled from 43 sites throughout the Gulf of Mexico from Brownsville, Texas, to the Florida Everglades from 1986 to 1989. Oysters were analysed for body burden of a suite of metals and petroleum aromatic hydrocarbons (PAHs), the prevalence and intensity of the oyster pathogen, Perkinsus marinus, and condition index. The contaminants fell into two groups based on the spatial distribution of body burden throughout the Gulf. Arsenic, selenium, mercury and cadmium were characterized by clinal reduction in similarity with distance reminiscent of that followed by mean monthly temperature and precipitation. Zinc, copper, PAHs and silver showed no consistent geographic trend. Within local regions, industrial and agricultural and use and P. marinus prevalence and infection intensity frequently correlated with body burden. Contaminants and biological attributes followed one of three temporal trends. Zinc, copper and PAHs showed concordant shifts over 4 years throughout the eastern and southern Gulf. Mercury and cadmium showed concordant shifts in the northwestern Gulf. Selenium, arsenic, length, condition index and P. marinus prevalence and infection intensity showed concordant shifts throughout most of the entire Gulf. Concordant shifts suggest that climatic factors, the El Niño/Southern Oscillation being one example, exert a strong influence on biological attributes and contaminant body burdens in the Gulf. Correlative factors are those that probably affect or indicate the rate of tissue turnover and the frequency of reproduction; namely, temperature, disease intensity, condition index and length.

    Levels of imposex (superimposition of male characters, upon females) and the presence of sterile females are assessed in the gastropod Nassarius nitidus (Jeffreys, 1867), at 22 locations in the Basque Country (northern Spain). At 18 of these localities, butyltin bioaccumulation (tributyltin (TBT); dibutyltin; monobutyltin) was analysed using isotope dilution and GC-ICP-MS. Higher imposex levels and TBT body burden were found in confined harbours, with a large vessel traffic or the presence of a fishing fleet or a shipyard. For the first time, four apparently sequential types of aborted capsules are described in this species. Another novelty is the interspecific comparison between imposex intensities in sympatrically living populations of N. nitidus and N. reticulatus. This showed that sensitivity to TBT pollution of both species is relatively similar (in terms of Relative Penis Length Index). Since N. nitidus has a restricted habitat distribution due to its low presence in wave-exposed habitats, its complementary use with other species is recommended for its use in TBT monitoring programmes.

    Seasonal variation in abiotic and biotic environments may modify the toxicity of organic chemicals for aquatic organisms. In present study, survival of the freshwater clam Pisidium amnicum was studied in laboratory exposures to pentachlorophenol (PCP) in April (at 5 degress C) and July (at 19 degress C). Behavioral responses, mean survival times (MSTs), and the lethal body burdens (LBBs) of PCP for uninfected clams and for clams infected by digenean trematodes were determined separately in two PCP concentrations, 100 and 300 microgram/L. Analysis of data revealed reduced behavioral activity of the clams in the PCP exposure compared to that in the control. The time needed for toxic responses was greatly affected by temperature; MSTs were 5 to 15 times longer in winter than at summer temperatures. Unexpectedly, the infected clams in summer were more tolerant to PCP than the uninfected clams. Despite the differences in survival times, the LBBs between the seasons were constant. However, in summer, the infected clams had significantly higher LBBs than the uninfected clams. The differences in survival and LBBs between the infected and uninfected clams are suggested to be caused by the high lipid contents found in parasites, which may change the internal distribution of PCP.

  7. Adjustment of a direct method for the determination of man body burden in Pu-239 on by X-ray detection of U-235

    International Nuclear Information System (INIS)

    The use of Pu-239 on a larger scale sets a problem about the contamination measurement by aerosol at lung level. A method of direct measurement of Pu-239 lung burden is possible, thanks to the use of a large area window proportional counter. A counter of such pattern, has been especially carried out for this purpose. The adjustment of the apparatus allows an adequate sensibility to detect a contamination at the maximum permissible body burden level. Besides, a method for individual 'internal calibration', with a plutonium mock: the protactinium-233, is reported. (author)

  8. The significance of mineral pollutants in hair for the assessment of the body burden and the concentration in the critical organs in laboratory animals

    International Nuclear Information System (INIS)

    If the content of an element in hair of an individual is used for the assessment of health risk of that person it is of special importance to know if the hair analytical data reflect the body burden or the content of the organ or tissues at risk. Ideally the content in hair should rise and fall in parallel to an increase or decrease of the body burden or the content in the critical organs. It was the aim of this project to study the transfer of Hg, methyl-mercury and Zn to hair and to compare it with the levels simultaneously observed in the total body and the relevant organs under controlled experimental conditions in an animal model. In addition, a similar study on As and the analyses of two experiments of a long term study on Cd exposure were also included. 11 refs, 3 figs, 4 tabs

    While environmental risk assessment is typically based on toxicant concentrations in water and/or sediment, awareness is increasing that internal concentrations or body burdens are the key to understand adverse effects in organisms. In order to link environmental micropollutants as causes of observed effects, there is an increasing demand for methods to analyse these chemicals in organisms. Here, a multi-target screening method based on pulverised liquid extraction (PuLE) and a modified QuEChERS approach with an additional hexane phase was developed. It is capable to extract and quantify organic micropollutants of diverse chemical classes in freshwater invertebrates. The method was tested on gammarids from the Danube River (within the Joint Danube Survey 3) and target compounds were analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Furthermore, a non-target screening using high resolution-tandem mass spectrometry (LC-HRMS/MS) was conducted. A total of 17 pollutants were detected and/or quantified in gammarids at low concentrations. Pesticide concentrations ranged from 0.1 to 6.52 ng g(-1) (wet weight), those of wastewater-derived pollutants from 0.1 to 2.83 ng g(-1) (wet weight). The presence of wastewater-derived pollutants was prominent at all spots sampled. Using non-target screening, we could successfully identify several chlorinated compounds. These results demonstrate for the first time the presence of pesticides and wastewater-derived pollutants in invertebrates of the Danube River. PMID:27064613

  11. Body burdens of brominated flame retardants and other persistent organo-halogenated compounds and their descriptors in US girls

    International Nuclear Information System (INIS)

    Background: Levels of brominated flame retardants are increasing in US populations, yet little data are available on body burdens of these and other persistent hormonally active agents (HAAs) in school-aged children. Exposures to such chemicals may affect a number of health outcomes related to development and reproductive function. Objective: Determine the distribution of biomarkers of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and organo-chlorinated pesticides (OCPs), such as DDT/DDE, in children, and their variation by key descriptor variables. Methods: Ethnically diverse cohorts of girls 6-8 y old at baseline are being followed for growth and pubertal development in a multi-site, longitudinal study. Nearly 600 serum samples from the California and Ohio sites were analyzed for lipids, 35 PCB congeners, 11 PBDE congeners, and 9 OCPs. The biomarker distributions were examined and geometric means compared for selected analytes across categories of age, race, site, body mass index (BMI), parental education, maternal age at delivery, and breast feeding in adjusted models. Results: Six PBDE congeners were detected among greater than 70% of samples, with BDE-47 having the highest concentration (median 42.2, range 4.9-855 ng/g lipid). Girls in California had adjusted geometric mean (GM) PBDE levels significantly higher than girls in Ohio. Furthermore, Blacks had significantly higher adjusted GMs of all six PBDE congeners than Whites, and Hispanics had intermediate values. GMs tended to be lower among more obese girls, while other variables were not strongly associated. In contrast, GMs of the six PCB congeners most frequently detected were significantly lower among Blacks and Hispanics than Whites. PCBs and the three pesticides most frequently detected were also consistently lower among girls with high BMI, who were not breast-fed, whose mothers were younger, or whose care-givers (usually parents) were less educated.

    Secondhand smoke was classified by national and international organisations as a known cause of cancer in humans and has many adverse health effects, especially cardiovascular diseases and lung tumours. Global studies have clearly shown that hospitality venues have the highest levels of indoor air pollution containing different substances that are clearly carcinogenic--such as tobacco-related chemicals--compared with other, smoke-free indoor spaces. Data from the human biomonitoring of non-smoking employees in the food service industry confirm this high exposure level. Non-smokers exposed to secondhand smoke in these environments are at increased risk for adverse health effects. The consistent protection of non-smokers in public places such as restaurants and bars through a smoking ban results in a significant reduction of the pollutants in the air (mostly > 90%) and clearly reduces the internal body burden for users and employees. Furthermore, health complaints by non-smoking employees are reduced and the higher risk for lung tumours of employees in the food service industry compared with the general population can be effectively reduced as well. According to current standards of knowledge, other measures such as spatial separation of smoking areas or the use of mechanical venting systems do not achieve a comparably high and effective pollutant reduction under field conditions. Studies concerning the economic effects of prohibiting smoking in public places conducted in various countries have shown that beverage-focused gastronomic enterprises experience a short-term down trend but that food-focused gastronomic enterprises do not experience any negative or even positive effects. The positive effects of a ban on smoking in public places on the general population are a decline in cigarette consumption and the reduction of secondhand smoke exposure by non-smokers. Smoking bans in hospitality venues are not necessarily linked with a shift of the tobacco consumption to

    This paper reviews the levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in different environmental media, human body burdens and health risk assessment results at e-waste recycling sites in China. To provide an indication of the seriousness of the pollution levels in the e-waste recycling sites in China, the data are compared with guidelines and available existing data for other areas. The comparison clearly shows that PCDD/Fs derived from the recycling processes lead to serious pollution in different environmental compartments (such as air, soil, sediment, dust and biota) and heavy body burdens. Of all kinds of e-waste recycling operations, open burning of e-waste and acid leaching activities are identified as the major sources of PCDD/Fs. Deriving from the published data, the estimated total exposure doses via dietary intake, inhalation, soil/dust ingestion and dermal contact are calculated for adults, children and breast-fed infants living in two major e-waste processing locations in China. The values ranged from 5.59 to 105.16 pg WHO-TEQ/kg bw/day, exceeding the tolerable daily intakes recommended by the WHO (1–4 pg WHO-TEQ/kg bw/day). Dietary intake is the most important exposure route for infants, children and adults living in these sites, contributing 60–99% of the total intakes. Inhalation is the second major exposure route, accounted for 12–30% of the total exposure doses of children and adults. In order to protect the environment and human health, there is an urgent need to control and monitor the informal e-waste recycling operations. Knowledge gaps, such as comprehensive dietary exposure data, epidemiological and clinical studies, body burdens of infants and children, and kinetics about PCDD/Fs partitions among different human tissues should be addressed. - Highlights: ► PCDD/F levels at e-waste recycling sites in China were reviewed. ► Data on environment and body burden and health risk assessment results were reviewed

  17. Association of PCB, PBDE and PCDD/F body burdens with hormone levels for children in an e-waste dismantling area of Zhejiang Province, China

    International Nuclear Information System (INIS)

    Increased electronic waste (e-waste) has raised public concerns regarding exposure to numerous toxic contaminants, particularly polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). In China, the body burdens of PCBs, PBDEs and PCDD/Fs are associated with thyroid hormones in populations from e-waste dismantling sites; however, it is unclear whether this association occurs in children. In this study, we determined the serum levels of PCBs, PBDEs and PCDD/Fs and the endocrine hormones including free triiodothyronine (FT3), total triiodothyronine (TT3), free thyroxine (FT4), total thyroxine (TT4), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), cortisol and growth hormone (GH) in 21 children from an e-waste dismantling area and 24 children from a control area. The results showed that the mean levels of ∑ PCBs and ∑ PBDEs in the exposure group were significantly higher than in the control group (40.56 and 32.09 ng g−1 lipid vs. 20.69 and 8.43 ng g−1 lipid, respectively, p < 0.01 for each), and the mean level of ∑ PCDD/Fs in the exposure group was higher than in the control group, but the difference was not significant (206.17 vs. 160.27 pg g−1 lipid, p > 0.05). For the endocrine hormones, we did not find significant differences between the exposed and control groups, although the mean levels of FT3, TT3, TT4, ACTH, cortisol and GH were higher, whereas the mean levels of FT4 and TSH were lower in the exposed group. The mean level of ∑ PBDEs was positively correlated with the mean levels of ∑ PCBs (r = 0.60, p < 0.05) and ∑ PCDD/Fs (r = 0.61, p < 0.05). Furthermore, the mean level of ∑ PBDEs was positively correlated with ACTH (r = 0.61, p < 0.05). In conclusion, our data suggested that exposure to e-waste dismantling environment increased the body burdens of PCBs and PBDEs in local children and that these contaminants released from the e

    An evaluation of suitability of applying hair as a noninvasive indicator for determination of the body burden mercury in mammals was carried out by determining the concentration of mercury in hair and liver tissue of the golden jackal, Canis aureus . Nineteen jackals killed on the roads along the Caspian Sea in the central region of Mazandaran Province, Iran were collected. The mercury measurements were carried out by AMA254 LECO and the standard method ASTM-D6722. SPSS and Excel were used for analytical statistics. There was a significant difference in Hg levels between the hair and liver tissue (P < 0.001). The average concentration of mercury was 187.3 + or - 22.7 and 53.3 + or - 7.3 ng/g, respectively. No significant differences were seen either between the sexes or in correlation between the tissues. But a significant and positive relation was seen between the mercury content in hair and body weight and length (P < 0.005). In general, the mercury concentration was less than the deleterious, effective limit on the species. It seems that this is the first study of Hg concentrations in jackals and demonstrates on easy and noninvasive sampling method. PMID:20596768

    Full Text Available Common carotid intima media thickness (CIMT and ankle brachial pressure index (ABPI are used as surrogate marker of atherosclerosis, and have been shown to correlate with arterial stiffness, however their correlation with global atherosclerotic burden has not been previously assessed. We compare CIMT and ABPI with atheroma burden as measured by whole body magnetic resonance angiography (WB-MRA.50 patients with symptomatic peripheral arterial disease were recruited. CIMT was measured using ultrasound while rest and exercise ABPI were performed. WB-MRA was performed in a 1.5T MRI scanner using 4 volume acquisitions with a divided dose of intravenous gadolinium gadoterate meglumine (Dotarem, Guerbet, FR. The WB-MRA data was divided into 31 anatomical arterial segments with each scored according to degree of luminal narrowing: 0 = normal, 1 = <50%, 2 = 50-70%, 3 = 70-99%, 4 = vessel occlusion. The segment scores were summed and from this a standardized atheroma score was calculated.The atherosclerotic burden was high with a standardised atheroma score of 39.5±11. Common CIMT showed a positive correlation with the whole body atheroma score (β 0.32, p = 0.045, however this was due to its strong correlation with the neck and thoracic segments (β 0.42 p = 0.01 with no correlation with the rest of the body. ABPI correlated with the whole body atheroma score (β -0.39, p = 0.012, which was due to a strong correlation with the ilio-femoral vessels with no correlation with the thoracic or neck vessels. On multiple linear regression, no correlation between CIMT and global atheroma burden was present (β 0.13 p = 0.45, while the correlation between ABPI and atheroma burden persisted (β -0.45 p = 0.005.ABPI but not CIMT correlates with global atheroma burden as measured by whole body contrast enhanced magnetic resonance angiography in a population with symptomatic peripheral arterial disease.

    Adult male Common Carp were sampled in 2007/08 over a full reproductive cycle at Lake Mead National Recreation Area. Sites sampled included a stream dominated by treated wastewater effluent, a lake basin receiving the streamflow, an upstream lake basin (reference), and a site below Hoover Dam. Individual body burdens for 252 contaminants were measured, and biological variables assessed included physiological [plasma vitellogenin (VTG), estradiol-17β (E2), 11-ketotestosterone (11KT)] and organ [gonadosomatic index (GSI)] endpoints. Patterns in contaminant composition and biological condition were determined by Principal Component Analysis, and their associations modeled by Principal Component Regression. Three spatially distinct but temporally stable gradients of contaminant distribution were recognized: a contaminant mixture typical of wastewaters (PBDEs, methyl triclosan, galaxolide), PCBs, and DDTs. Two spatiotemporally variable patterns of biological condition were recognized: a primary pattern consisting of reproductive condition variables (11KT, E2, GSI), and a secondary pattern including general condition traits (condition factor, hematocrit, fork length). VTG was low in all fish, indicating low estrogenic activity of water at all sites. Wastewater contaminants associated negatively with GSI, 11KT and E2; PCBs associated negatively with GSI and 11KT; and DDTs associated positively with GSI and 11KT. Regression of GSI on sex steroids revealed a novel, nonlinear association between these variables. Inclusion of sex steroids in the GSI regression on contaminants rendered wastewater contaminants nonsignificant in the model and reduced the influence of PCBs and DDTs. Thus, the influence of contaminants on GSI may have been partially driven by organismal modes-of-action that include changes in sex steroid production. The positive association of DDTs with 11KT and GSI suggests that lifetime, sub-lethal exposures to DDTs have effects on male carp opposite of those

    Musculature from the dorsal region of 130 largemouth bass (Micropterus salmoides), 140 sunfish (Lepomis sp.), 41 spotted seatrout (Cynoscion nebulosus) and 67 striped mullet (Mugil cephalus) were collected from five estuarine and five freshwater sites within the St. Marks National Wildlife Refuge and two estuarine and two freshwater sites from St. Andrew Bay, Florida, United States of America. Musculature was analyzed for total mercury content, sagittal otoliths were removed for age determination and physiological responses were measured. Largemouth bass and sunfish from the refuge had higher mercury concentrations in musculature than those from the bay. Male spotted seatrout, male striped mullet, male and female sunfish and female largemouth bass had mercury burdens positively correlated with length. The majority of all four species of fish from both study areas contained mercury levels below 1.5 part per million, the limit for safe consumption recommended the Florida Department of Health. In comparison, a significant percentage of largemouth bass and sunfish from several sampled sites, most notably Otter Lake and Lake Renfroe within St. Marks National Wildlife Refuge, had mercury levels consistent with the health department's guidelines of 'limited consumption' or 'no consumption guidelines.'

    In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4-9 g/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 g/g. In the present study we examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. While Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the five year period since the spill. Our results are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, our results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

    The paper presents a new sampling method for studying in-body radioactive contamination by bone-seeking radionuclides such as {sup 90}Sr, {sup 239+240}Pu, {sup 238}Pu, {sup 241}Am and selected gamma-emitters, in human bones. The presented results were obtained for samples retrieved from routine surgeries, namely knee or hip joints replacements with implants, performed on individuals from Southern Poland. This allowed to collect representative sets of general public samples. The applied analytical radiochemical procedure for bone matrix is described in details.

  5. Human bones obtained from routine joint replacement surgery as a tool for studies of plutonium, americium and 90Sr body-burden in general public

    International Nuclear Information System (INIS)

    The paper presents a new sampling method for studying in-body radioactive contamination by bone-seeking radionuclides such as 90Sr, 239+240Pu, 238Pu, 241Am and selected gamma-emitters, in human bones. The presented results were obtained for samples retrieved from routine surgeries, namely knee or hip joints replacements with implants, performed on individuals from Southern Poland. This allowed to collect representative sets of general public samples. The applied analytical radiochemical procedure for bone matrix is described in details. Due to low concentrations of 238Pu the ratio of Pu isotopes which might be used for Pu source identification is obtained only as upper limits other then global fallout (for example Chernobyl) origin of Pu. Calculated concentrations of radioisotopes are comparable to the existing data from post-mortem studies on human bones retrieved from autopsy or exhumations.

WB-MTV, whole-body total lesion glycolysis (WB-TLG and a set of semi-quantitative imaging-based parameters were analyzed both on a per-patient and a per-lesion basis.On a per-lesion basis, malignant PNSTs demonstrated both a significantly higher MTV and TLG than benign PNSTs (p < 0.0001. On a per-patient basis, WB-MTV and WB-TLG were significantly higher in patients with malignant PNSTs compared to patients with benign PNSTs (p < 0.001. ROC analysis showed that MTV and TLG could be used to differentiate between benign and malignant tumors.WB-MTV and WB-TLG may identify malignant change and may have the potential to provide a basis for investigating molecular biomarkers that correlate with metabolically active disease manifestations. Further evaluation will determine the potential clinical impact of these PET-based parameters in NF1.

    International Nuclear Information System (INIS)

    At the request of the IAEA, the authors have performed an assessment of the analytical quality and the interpretation of the trace element data obtained within the framework of the IAEA Co-ordinated Research Programme (CRP) on The Significance of Hair Mineral Analysis as a Means of Assessing Internal Body Burdens of Environmental Pollutants. In this CRP research groups from various countries participated, using different analytical procedures, based on NAA, XRF and AAS. Data have been collected for Zn, CU, Pb, Cd, As, Hg, and Se in male human hair, liver, kidney, lung, brain, and bone. The samples analyzed originated from China, Hungary, Bulgaria, Japan, the former GDR, Sweden and Norway. The analytical quality of the data has been assessed on basis of the calculated limits of quantitation per trace element determined, per tissue analyzed and per participant, as well as from the trace element values found for reference materials and ''blind'' materials. The analytical quality of the data differs widely, from generally good to reasonable (Zn, Cu, and Se) to generally inadequate to strongly inadequate (Pb, Cd, As, and Hg). 15 refs, 29 tabs

    Chronic venous disease is a common condition with clinical signs and symptoms ranging from spider veins, to varicose veins, to active venous ulceration. Both superficial and deep venous dysfunction may be implicated in the development of this disease. Socio-economic factors are shaping our population, with increasing age and body mass index resulting in significant pressure on healthcare systems worldwide. These risk factors also lead to an increased risk of developing superficial and/or deep venous insufficiency, increasing disease prevalence and morbidity. In this chapter, the authors review the current and future burden of chronic venous disease from an epidemiological, quality of life and economic perspective. PMID:26916773

    International Nuclear Information System (INIS)

    A compilation of data on the whole-body burden of 134Cs, 137Cs and 40K in various Swedish populations between 1964 and 2002 has been made. The compilation was carried out in co-operation with the Department of Radiation Physics in Malmoe, the Swedish Radiation Protection Authority (SSI), the Swedish Defence Research Agency Department (FOI) and the Department of Radiation Physics, Goeteborg University. Individual body burden values have been inserted into a calculation spread sheet, with data on body weight, gender, age, occupation (if available) and place of residence. The database enables a study of the time-pattern and geographical dependence of radiocaesium transfer from ground deposition to man, and the associated absorbed dose. The Swedish government has assigned SSI the responsibility for obtaining and assuring one of Sweden's national environmental quality objectives, A Safe Radiation Environment. A natural consequence of this responsibility is that a means for quantifying progress towards the objective is necessary. The data compilation discussed here is one important component in the national environmental monitoring programme that is currently (2002) being developed at SSI. The new program for monitoring environmental radiation has the goal of following geographical and ecological differences in the radiological effects to both mankind and the environment, and assessing relevant doses and risks. During the period between 1964 and 2002, fallout of radiocaesium from nuclear weapons tests (only 137Cs) and from the Chernobyl accident in 1986 (both 134Cs and 137Cs) have occurred in Sweden. The ground deposition of the radiocaesium has gradually been transferred through different ecological pathways to man. From the database it can be deduced that large regional variations in the body burden of radiocaesium in man have occurred through this period. Three populations exhibit considerably higher body content levels than others; (i) reindeer herders in central

    Full Text Available Objectives: The main objective is to determine the degree of burden in the main caregivers of dependent patients, to analyse the profile of informal caregivers and dependent patients. Their claims and help received with caring, the influence of mental deteriorate and duration of care giving regarding the burden of caregivers.Methods: Descriptive cross-sectional observational study amongst 50 caregivers and dependents. We used descriptive statistics and correlational studies. Results: 86 % of caregivers were women, middle aged, son/daughter of the dependent, married, with basic studies, no work outside the home, the average time in the role of caregiver was 16,96 hours a day and 2,1 free hours a day. 64 % of them received family support and 68 % wish to receive economic aid. It was found that for 38 % of the caregivers there was no burden at all, 34 % of them had a minimum burden and 28 % a greater burden.Conclusion: There are some caregivers with moderate or great burden. Our caregiver wishes to receive economic help. Our research shows that the decrease of mental health and the years of evolution do not have a significant statistically influence on caregivers. It is necessary prioritize the interventions and its recipients, provide solutions for caregivers with a greater burden, trying to keep away “caregiver syndrome”.

Design: A pilot cross-sectional study. Patients and methods: Between March and May of 2006, data were collected on 35 over 60 years old patients who live in the community of Buenaventura, with a score in the Barthel index Results: The mean age and the standard deviation of the patient group was 78.9±10 years. There was a larger proportion of women (68.5%. In the care givers, the regular age and the standard deviation was 49.4±18.8 years, where 91% were women. It was found that for 54.2% of the caregivers there was no burden at all, 40% of them had a minimum burden and the others a greater burden. Bivariate analysis between the care giver’s burden and the number of chronic disease, the score on the minimental test, elderly depression and the family APGAR, resulted in statistic association (p Conclusions: There is an association between aged people, dependent in basic common day activities related with physical aspects, and care giver’s burden. Being the caregivers mostly family members, further studies must be focused on identifying and realizing interventions to prevent or limit the decrease of declining mental health and loss of life quality and the consequent increase of the care giver’s burden.

    Burns, Alistair

    2000-07-01

    Alzheimer's disease (AD) imposes a severe burden upon patients and their carers. In particular, family carers of AD patients face extreme hardship and distress that represents a major but often hidden burden on healthcare systems. Carers often experience clinically significant alterations in physical and mental health, particularly depression. A number of individual features of the dementia syndrome that are known to be particularly burdensome to carers include the degree of cognitive impairment, amount of help required with activities of daily living, personality changes and the presence of psychiatric symptoms and behavioural disturbances. The neuropsychiatric features of AD patients can adversely impact the relationship between the patient and caregiver generating feelings of strain, burden and social isolation. Individual characteristics of the caregiver including personality, gender, degree of formal and informal support and physical and mental health, as well as attributional style ('coping style') and expressed emotion (critical or hostile attitudes), also dictate carer burden. As informal caregivers play such a crucial role in the care of AD patients, appropriate management strategies that incorporate interventions which address the specific burdens of the individual caregiver are essential. Reducing the burden of care can be achieved by the combination of a number of individual and general measures, including education, respite and emotion-focused interventions. These measures, accompanied by non-pharmacological strategies, are extremely important in the total care of the AD patient, with the emphasis on maintaining people in the community as long as possible.

    The use of Pu-239 on a larger scale sets a problem about the contamination measurement by aerosol at lung level. A method of direct measurement of Pu-239 lung burden is possible, thanks to the use of a large area window proportional counter. A counter of such pattern, has been especially carried out for this purpose. The adjustment of the apparatus allows an adequate sensibility to detect a contamination at the maximum permissible body burden level. Besides, a method for individual 'internal calibration', with a plutonium mock: the protactinium-233, is reported.

    Full Text Available Duration of human life has been substantially increased in the last fifty years. Survivals of diseases have been prolonged through the advances in medicine. Together with these gratifying consequences, there appeared novel difficulties to cope with. Furthermore developments including globalization, industrialization and transition from rural to urban life occurred during the last century; so family units became smaller and numbers of members on employment in family units increased. As a result numbers of family members to undertake the responsibility of care decreased. As a concept, caregiver burden expresses physical, psychosocial and financial reactions during the course of care providing. Distinct factors including structures of social, cultural and family units and health care systems may affect conditions of care. Caregiver’s age, gender, ethnicity, education, relationship with the patient, attitude towards providing care, financial situation, coping abilities, her own health, beliefs, social support and cultural pattern are the personal factors that are related to perception of caregiver burden. Burden of care giving is geared to differential aspects of care needs. For instance care needs of physically disabled and medical care requiring patients with spinal cord injuries may differ from care needs of chronic psychiatric disorders, demented patients in advanced age of their lives or cancer patients in terminal periods. Strain due to care giving may differ as a result of properties of care demands. It is aimed to review the burden of caregivers in different medical and psychiatric care requiring conditions and to introduce differential aspects of caregiver burden in these different conditions.

    Krug, E G; Sharma, G K; Lozano, R

    2000-04-01

    The traditional view of injuries as "accidents", or random events, has resulted in the historical neglect of this area of public health. However, the most recent estimates show that injuries are among the leading causes of death and disability in the world. They affect all populations, regardless of age, sex, income, or geographic region. In 1998, about 5.8 million people (97.9 per 100,000 population) died of injuries worldwide, and injuries caused 16% of the global burden of disease. Road traffic injuries are the 10th leading cause of death and the 9th leading cause of the burden of disease; self-inflicted injuries, falls, and interpersonal violence follow closely. Injuries affect mostly young people, often causing long-term disability. Decreasing the burden of injuries is among the main challenges for public health in the next century--injuries are preventable, and many effective strategies are available. Public health officials must gain a better understanding of the magnitude and characteristics of the problem, contribute to the development and evaluation of injury prevention programs, and develop the best possible prehospital and hospital care and rehabilitation for injured persons.

    2015-04-01

    An estimation of the global stratospheric burden of carbonyl sulfide (OCS) calculated using satellite based measurements from the Atmospheric Chemistry Experiment - Fourier Transform Spectrometer (ACE-FTS) will be presented. OCS is the most abundant sulfur containing gas in the atmosphere in the absence of volcanic eruptions. With a long lifetime of 2-6 years it reaches the stratosphere where it is photolyzed and the sulfur oxidized and condensed to aerosols, contributing to the stratospheric aerosol layer. The aerosol layer is the one factor of the middle-atmosphere with a direct impact on the Earth's climate by scattering incoming solar radiation back to space. Therefore it is crucial to understand and estimate the different processes and abundances of the species contributing to the aerosol layer. However, the exact amount of OCS in the stratosphere has not been quantified yet. A study on the OCS mixing ratio distribution based on ACE-FTS data has already been made by Barkley et al. (2008), also giving an estimation for the total atmospheric OCS mass. ACE-FTS is an infrared solar occultation spectrometer providing high- resolution profile observations since 2004. In the scope of this work the focus lies on the stratospheric OCS burden, calculated by integrating the ACE profiles. A global overview on the stratospheric OCS amount in the past and present based on the ACE data as well as a look at regional and seasonal variability will be given. Furthermore, the results of this work will be useful for further studies on OCS fluxes and lifetimes, and in quantifying the contribution of OCS to the global stratospheric sulfur burden.

Mood disorders, as defined by the World Mental Health and the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, have a 12-month prevalence which varies from 3% in Japan to over 9% in the US. A recent American survey found the prevalence of current depression to be 9% and the rate of current major depression to be 3.4%. All studies of depressive disorders have stressed the importance of the mortality and morbidity associated with depression. The mortality risk for suicide in depressed patients is more than 20-fold greater than in the general population. Recent studies have also shown the importance of depression as a risk factor for cardiovascular death. The risk of cardiac mortality after an initial myocardial infarction is greater in patients with depression and related to the severity of the depressive episode. Greater severity of depressive symptoms has been found to be associated with significantly higher risk of all-cause mortality including cardiovascular death and stroke. In addition to mortality, functional impairment and disability associated with depression have been consistently reported. Depression increases the risk of decreased workplace productivity and absenteeism resulting in lowered income or unemployment. Absenteeism and presenteeism (being physically present at work but functioning suboptimally have been estimated to result in a loss of $36.6 billion per year in the US. Worldwide projections by the World Health Organization for the year 2030 identify unipolar major depression as the leading cause of disease burden

  10. The Assessment of Radioactive Body Burdens of the Alkaline Earths

    International Nuclear Information System (INIS)

    The difficulties in obtaining data on the metabolism of bone-seeking radioactive isotopes in man are widely appreciated, especially on the distribution of the isotope between different bones and the microscopic distribution within the same bone. If a full understanding of the metabolism in man is to be obtained, there is at present no alternative but to resort to the use of experimental animals. The calcium and strontium metabolism of the rabbit, which is the smallest animal to have similar skeletal structure to that of human bone, has been studied. The research was planned to include as many parameters as possible. These included specific activity measurements of plasma, urine and faeces, total retention in the skeleton as well as individual bones and in some cases soft tissue. In addition the microscopic distribution of the isotope was studied by quantitative autoradiographic techniques at different time intervals. The results have been considered in the light of various models proposed for the retention of bone-seeking isotopes in mammals and the limitations of each of these models have been assessed. Measurements have been made over sufficiently long time intervals compared with the life-span of the rabbit to enable predictions to be made about the long-term behaviour in man. The results indicate that none of the existing models is completely satisfactory but that a modification of the power function is the most useful. The importance of exchange, as well as resorption, for the removal of radioactive isotopes from the skeleton is well illustrated by the quantitative autoradiographic measurements. (author)

    Mathematical models for burden descending process have been applied to obtain whole burden structures in blast furnace,whereas the accuracy of those burden descent models has not been sufficiently investigated.Special evaluation method based on timeline burden profiles was established to quantitatively evaluate the error between ex-perimental and modeled burden structures.Four existing burden descent models were utilized to describe the burden structure of a 1/20 scaled warm blast furnace.Input modeling conditions including initial burden profile,descending volumes in each time interval,and normalized descending velocity distribution were determined via special image pro-cessing technology.Modeled burden structures were evaluated combined with the published experimental data.It is found that all the models caught the main profile of the burden structure.Furthermore,the improved nonuniform de-scent model (Model IV)shows the highest level of precision especially when burden descends with unstable velocity distribution tendency.Meanwhile,the traditional nonuniform descent model (Model III)may also be desirable to model the burden descending process when the burden descending velocity presents a linear tendency.Finally,the uni-form descent model (Model I)might be the first option for roughly predicting burden structure.

    This paper presents an argument-based logic for reasoning about allocations of the burden of persuasion. The logic extends the system of Prakken (2001), which in turn modified the system of Prakken & Sartor (1996) with the possibility to distribute the burden of proof over both sides in an argument

    Full Text Available BACKGROUND: Most analyses of risks to health focus on the total burden of their aggregate effects. The distribution of risk-factor-attributable disease burden, for example by age or exposure level, can inform the selection and targeting of specific interventions and programs, and increase cost-effectiveness. METHODS AND FINDINGS: For 26 selected risk factors, expert working groups conducted comprehensive reviews of data on risk-factor exposure and hazard for 14 epidemiological subregions of the world, by age and sex. Age-sex-subregion-population attributable fractions were estimated and applied to the mortality and burden of disease estimates from the World Health Organization Global Burden of Disease database. Where possible, exposure levels were assessed as continuous measures, or as multiple categories. The proportion of risk-factor-attributable burden in different population subgroups, defined by age, sex, and exposure level, was estimated. For major cardiovascular risk factors (blood pressure, cholesterol, tobacco use, fruit and vegetable intake, body mass index, and physical inactivity 43%-61% of attributable disease burden occurred between the ages of 15 and 59 y, and 87% of alcohol-attributable burden occurred in this age group. Most of the disease burden for continuous risks occurred in those with only moderately raised levels, not among those with levels above commonly used cut-points, such as those with hypertension or obesity. Of all disease burden attributable to being underweight during childhood, 55% occurred among children 1-3 standard deviations below the reference population median, and the remainder occurred among severely malnourished children, who were three or more standard deviations below median. CONCLUSIONS: Many major global risks are widely spread in a population, rather than restricted to a minority. Population-based strategies that seek to shift the whole distribution of risk factors often have the potential to

    International Nuclear Information System (INIS)

    The radiation burden from 137Cs sources on 22 children from a small Byelorussian village was studied from 1992 to 1994. Foodstuff, whole body burden and urinary excretion of 137Cs were measured, intake rates, biological half-lives and doses were calculated. The median value for the 137Cs whole body incorporation level was found to be 124 Bq, the biological half life was calculated as 68 d for girls and 50 d for boys. The internal dose caused by 137Cs was found to be negligible in comparison to that from external sources. No deviation from normal values could be shown in simultaneously studied clinico-chemical parameters

    Full Text Available Abstract Background We constructed a concise multidimensional care burden scale that reflects circumstances unique to Japan, with a focus on intractable neurological diseases. We surveyed 646 family caregivers of patients with intractable neurological diseases or stroke using 28 preliminary care burden scale items obtained from qualitative research. The results were used to finalize the feeling of care burden scale (BIC: burden index of caregivers, and verify its reliability and validity. Methods The survey was conducted among caregivers providing home health care to patients with intractable neurological diseases (PD [Parkinson's disease], SCD [spinocerebellar degeneration], MSA [multiple system atrophy], and ALS [amyotrophic lateral sclerosis] or CVA (cerebrovascular accident using a mailed, self-administered questionnaire between November, 2003 and May, 2004. Results Response rates for neurological and CVA caregivers were 50% and 67%, respectively, or 646 in total (PD, 279; SCD, 78; MSA, 39; ALS, 30; and CVA, 220. Item and exploratory factor analyses led to a reduction to 11 items, comprising 10 items from the 5 domains of time-dependent burden, emotional burden, existential burden, physical burden, and service-related burden; and 1 item on total burden. Examination of validity showed a moderate correlation between each domain of the BIC and the SF-8 (Health related quality of life scale, Short Form-8, while the correlation coefficient of the overall BIC and CES-D was 0.62. Correlation between the BIC and ZBI, a preexisting care burden scale, was high (r = 0.84, while that with the time spent on providing care was 0.47. The ICC (Intraclass correlation coefficient by test-retest reliability was 0.83, and 0.68 to 0.80 by individual domain. Conclusion These results show that the BIC, a new care burden scale comprising 11 items, is highly reliable and valid.

Reasons for these symptoms are heterogeneous, varying from food allergy, food intolerance, irritable bowel syndrome to somatoform or other mental disorders. Literature reveals a large discrepancy between truly diagnosed food allergy and reports of food allergy symptoms by care seekers. In most studies currently available the characterization of patient groups is incomplete, because they did not distinguish between immunologic reactions and other kinds of food reactions. In analysing these adverse reactions, a thorough physical and psychological diagnostic approach is important. In our qualitative review, we present those diagnostic measures that are evidenced-based as well as clinically useful, and discuss the various psychological dimensions of adverse reactions to food. It is important to acknowledge the complex interplay between body and mind: Adults and children suffering from food allergy show impaired quality of life and a higher level of stress and anxiety. Pavlovian conditioning of adverse reactions plays an important role in maintaining symptoms. The role of personality, mood, or anxiety in food reactions is debatable. Somatoform disorders ought to be identified early to avoid lengthy and frustrating investigations. A future task will be to improve diagnostic algorithms, to describe psychological aspects in clearly characterised patient subgroups, and to develop strategies for an optimized management of the various types of adverse reactions to food.

    Hassett Afton L

    2010-07-01

    Full Text Available Abstract Juvenile arthritis comprises a variety of chronic inflammatory diseases causing erosive arthritis in children, often progressing to disability. These children experience functional impairment due to joint and back pain, heel pain, swelling of joints and morning stiffness, contractures, pain, and anterior uveitis leading to blindness. As children who have juvenile arthritis reach adulthood, they face possible continuing disease activity, medication-associated morbidity, and life-long disability and risk for emotional and social dysfunction. In this article we will review the burden of juvenile arthritis for the patient and society and focus on the following areas: patient disability; visual outcome; other medical complications; physical activity; impact on HRQOL; emotional impact; pain and coping; ambulatory visits, hospitalizations and mortality; economic impact; burden on caregivers; transition issues; educational occupational outcomes, and sexuality. The extent of impact on the various aspects of the patients', families' and society's functioning is clear from the existing literature. Juvenile arthritis imposes a significant burden on different spheres of the patients', caregivers' and family's life. In addition, it imposes a societal burden of significant health care costs and utilization. Juvenile arthritis affects health-related quality of life, physical function and visual outcome of children and impacts functioning in school and home. Effective, well-designed and appropriately tailored interventions are required to improve transitioning to adult care, encourage future vocation/occupation, enhance school function and minimize burden on costs.

  5. The disease burden of Taenia solium cysticercosis in Cameroon.

    Nicolas Praet

    Full Text Available BACKGROUND: Taenia solium cysticercosis is an important zoonosis in many developing countries. Human neurocysticercosis is recognised as an important cause of epilepsy in regions where the parasite occurs. However, it is largely underreported and there is a lack of data about the disease burden. Because a body of information on human and porcine cysticercosis in Cameroon is becoming available, the present study was undertaken to calculate the impact of this neglected zoonosis. METHODS: Both the cost and Disability Adjusted Life Year (DALY estimations were applied. All necessary parameters were collected and imported in R software. Different distributions were used according to the type of information available for each of the parameters. FINDINGS: Based on a prevalence of epilepsy of 3.6%, the number of people with neurocysticercosis-associated epilepsy was estimated at 50,326 (95% CR 37,299-65,924, representing 1.0% of the local population, whereas the number of pigs diagnosed with cysticercosis was estimated at 15,961 (95% CR 12,320-20,044, which corresponds to 5.6% of the local pig population. The total annual costs due to T. solium cysticercosis in West Cameroon were estimated at 10,255,202 Euro (95% CR 6,889,048-14,754,044, of which 4.7% were due to losses in pig husbandry and 95.3% to direct and indirect losses caused by human cysticercosis. The monetary burden per case of cysticercosis amounts to 194 Euro (95% CR 147-253. The average number of DALYs lost was 9.0 per thousand persons per year (95% CR 2.8-20.4. INTERPRETATION: This study provides an estimation of the costs due to T. solium cysticercosis using country-specific parameters and including the human as well as the animal burden of the zoonotic disease. A comparison with a study in South Africa indicates that the cost of inactivity, influenced by salaries, plays a predominant role in the monetary burden of T. solium cysticercosis. Therefore, knowing the salary levels and the

    Epidemiologic literature on stroke burden, patterns of stroke is almost non existent from Pakistan. However, several hospital-based case series on the subject are available, mainly published in local medical journals. Despite the fact that true stroke incidence and prevalence of stroke in Pakistan is not known, the burden is assumed to be high because of highly prevalent stroke risk factors (hypertension, diabetes mellitus, coronary artery disease, dyslipidemia and smoking) in the community. High burden of these conventional stroke risk factors is further compounded by lack of awareness, poor compliance hence poor control, and inappropriate management/treatment practices. In addition certain risk factors like rheumatic valvular heart disease may be more prevalent in Pakistan. We reviewed the existing literature on stroke risk factors in community, the risk factor prevalence among stroke patients, patterns of stroke, out come of stroke, availability of diagnostic services/facilities related to stroke and resources for stroke care in Pakistan.

    Full Text Available Attention Deficit/Hyperactivity Disorder (ADHD affects 5%–8% of children in the U.S. (10% of males and 4% of females. The contributions of multiple metal exposures to the childhood behavioral deficits are unclear, although particular metals have been implicated through their neurotoxicity. The objective of this study was to test the hypothesis that the body burden of Mn is positively correlated with ADHD symptoms. We also investigated the putative roles of Ca, Fe, Pb, and Hg. We collected shed molars from 266 children (138 boys and 128 girls who lost a tooth between 11 and 13 years of age. The molars were analyzed for metals using ICP-OES. The third grade teacher of each child completed the Teacher’s Disruptive Behavior Disorders Rating Scale (DBD to produce a score for “Total Disruptive Behavior” and subscale scores for “Attention Deficit Hyperactivity Disorder”, Hyperactivity/Impulsivity, Inattention, and Oppositional/Defiant. The mean Mn, Fe, Pb and Ca concentrations found in teeth was 6.1 ± 5.7 µg/g, 22.7 ± 24.1 µg/g, 0.9 ± 1.4 µg/g, and 6.0 × 105 ± 1.6 × 105 µg/g, respectively. Hg was not detected. No significant association was found between Mn and behavioral deficits. Ca was significantly negatively associated, and Pb showed a significant positive association with Hyperactivity/Impulsivity, Inattention, and Oppositional/Defiant Disorders. These findings call into question the putative independent association of manganese exposure and behavioral deficits in children, when the balance of other metallic burden, particularly Ca and Pb burdens play significant roles.

AA is clinically heterogenous, and its natural history is unpredictable. There is no preventative therapy or cure.Objective: The objective of this study is to provide an evidence-based systematic review on the epidemiology and the burden of AA.Methods and selection criteria: A search was conducted of the published, peer-reviewed literature via PubMed, Embase, and Web of Science. Studies published in English within the last 51 years that measured AA’s incidence, prevalence, distribution, disability-adjusted life years (DALYs, quality of life, and associated psychiatric and medical comorbidities were included. Two authors assessed studies and extracted the data.Results: The lifetime incidence of AA is approximately 2% worldwide. Both formal population studies found no sex predominance. First onset is most common in the third and fourth decades of life but may occur at any age. An earlier age of first onset corresponds with an increased lifetime risk of extensive disease. Global DALYs for AA were calculated at 1,332,800 in 2010. AA patients are at risk for depression and anxiety, atopy, vitiligo, thyroid disease, and other autoimmune conditions.Conclusion: AA is the most prevalent autoimmune disorder and the second most prevalent hair loss disorder after androgenetic alopecia, and the lifetime risk in the global population is approximately 2%. AA is associated with psychiatric and medical comorbidities including depression, anxiety, and several autoimmune disorders, and an increased global burden of disease.Keywords: hair loss, hair, prevalence, incidence, burden of disease

    Full Text Available Aim: of this research was to investigate, in Greek population, the degree of burden of caregivers of psychiatric patients, the ratio of burden and demographic and other factors. Finally, the purpose of this study was to evaluate the effect which, the burden, has on quality of life and mental health of caregivers. Materials and methods: For this purpose, specially constructed questionnaires were administered to 122 carers in structures belonging to the University Psychiatric Department of Eginition Hospital. Except of demographic data and variables related to their relative-patient, the participants filled out four psychometric tools: a the McMaster Family Assessment Device, b the quality of life questionnaire SF-12, c Zung’s self-rated depression scale and d the trait part of Spielberger’s State-Trait Anxiety Inventory. The study’s participants had variable age, family status, education, profession, gender and relationship with the psychiatric patient who was their relative. Results : The statistical analysis of the data showed that the carers reported low levels of health-related quality of life, both in the physical and in the mental component. The 20-40 years age group, the working and more educated class reported bigger distress in the physical dimension; in the mental dimension apart from the previous age group, worse quality of life was reported by relatives other than spouses. On the other hand, the burden levels show for the carers in our sample, were high in comparison with findings from other studies. Pensioners and/or homemakers, married, parents of psychiatric patients who cared for their relatives for a long period of time were proven more adjusted and resistant to burden. Older ages reported, though, higher levels of depression and anxiety. 20.8% of the participants gave answers indicative of clinical depression. In general, anxiety and depression as well as the mental component of the quality of life were found to be

    Complex caregiving issues occur in multigenerational families carrying the fragile X mutation and premutation. The same family members may care for children or siblings with fragile X syndrome (FXS) and for elderly parents with fragile X-associated tremor/ataxia syndrome (FXTAS). Family caregivers experience anxiety, depression, neglect of personal health care needs, employment difficulties, and loss of social support, leading to isolation and further psychiatric consequences. There is growing awareness of caregiver burden with regard to parents of children with FXS, but much less is known about the needs of informal caregivers of patients with FXTAS. In this paper, we review the available literature to date and provide suggestions for further exploration of caregivers' needs. Evidence-based strategies to address these needs are included. Many more research studies exploring caregiver burden in multigenerational fragile X families are needed, as well as studies aimed at investigating interventions and their impact on reduction.

    2016-08-31

    The burden of disease in haemophilia patients has wide ranging implications for the family and to society. There is evidence that having a current inhibitor increases the risk of morbidity and mortality. Morbidity is increased by the inability to treat adequately and its consequent disabilities, which then equates to a poor quality of life compared with non-inhibitor patients. The societal cost of care, or `burden of inhibitors', increases with the ongoing presence of an inhibitor. Therefore, it is clear that successful eradication of inhibitors by immune tolerance induction (ITI) is the single most important milestone one can achieve in an inhibitor patient. The type of factor VIII (FVIII) product used in ITI regimens varies worldwide. Despite ongoing debate, there is in vitro and retrospective clinical evidence to support the use of plasma-derived VWF-containing FVIII concentrates in ITI regimens in order to achieve early and high inhibitor eradication success rates.

    2016-10-01

    Diverticular disease (DD) of the colon represents a common clinical condition affecting from one-fourth to one-third of the population in developed countries. Several epidemiological studies have clearly shown that in the last decades the rates of clinic visits and hospital admissions for DD and its complications are progressively increased. In addition, complications of DD are associated to a high mortality rate that continues unabated despite advances in surgery and intensive care. As consequence, the burden on health care resources has significantly increased over time, leading DD among the main causes of health spending for gastrointestinal diseases. In this review the most important data regarding health care resources utilization and costs for DD are analyzed and some proposals for reducing the burden on health care systems are hypothesized.

    Full Text Available The disabling nature and lifelong impact of multiple sclerosis (MS imposes considerable socioeconomic burden despite its relative low prevalence compared to other chronic diseases. This is the first study of MS in the Slovak Republic that provides information about healthcare and social expenditures including costs of productivity loss caused by reduced work capacity of patients with MS. Retrospectively direct and indirect costs of MS were investigated by prevalence based “bottom-up” approach. The societal and health insurance perspective was used to perform the overall economic burden caused by MS in Slovakia. The human capital method was used for the calculation of indirect costs, as this is the most common method applied in published studies. As not all detailed data on expenditures were available, the missing data were collected in the retrospective patient research. Total annual costs in 2010 for 6.100 dispensed patients with MS in Slovakia were €54.723.592. Indirect costs (€31.728.757 prevailed over direct costs (€22.994.834. The highest part of both costs were €25.207.512 and €12.641.052 for loss productivity due to patients sickness and invalidity pensions and disease-modifying drugs respectively. The average cost per patient independently of disease severity was €8.971.MS causes a high economic burden, with a strong predominance of indirect costs. Documenting and quantifying this burden among patients with MS in different disease stages through cost-of-illness study can lead to better disease management and it can provide valuable information for future cost analysis and for decision-making process.

    2016-04-29

    Thromboembolic conditions were estimated to account for 1 in 4 deaths worldwide in 2010 and are the leading cause of mortality. Thromboembolic conditions are divided into arterial and venous thrombotic conditions. Ischemic heart disease and ischemic stroke comprise the major arterial thromboses and deep-vein thrombosis and pulmonary embolism comprise venous thromboembolism. Atrial fibrillation is a major risk factor for stroke and systemic arterial thromboembolism. Estimates of the global burden of disease were obtained from Global Burden of Disease Project reports, recent systematic reviews, and searching the published literature for recent studies reporting measures of incidence, burden, and disability-adjusted life-years. Estimates per 100 000 of the global incidence rate (IR) for each condition are ischemic heart disease, IR=1518.7; myocardial infarction, IR=139.3; ischemic stroke, IR=114.3; atrial fibrillation, IR=77.5 in males and 59.5 in females; and venous thromboembolism, IR=115 to 269. Mortality rates (MRs) for each condition are ischemic heart disease, MR=105.5; ischemic stroke, MR=42.3; atrial fibrillation, MR=1.7; and venous thromboembolism, MR=9.4 to 32.3. Global public awareness is substantially lower for pulmonary embolism (54%) and deep-vein thrombosis (44%) than heart attack (88%) and stroke (85%). Over time, the incidence and MRs of these conditions have improved in developed countries, but are increasing in developing countries. Public health efforts to measure disease burden and increase awareness of symptoms and risk factors need to improve, particularly in low- and middle-income regions to address this leading cause of morbidity and mortality.

    Full Text Available Background: Hemodialysis treatment is a costly procedure that requires specific resources. It has a considerable burden on patients, caregivers, and healthcare system. The aim of this study was to estimate the economic burden borne by the Ministry of Health (MOH in Jordan, with a focus on direct medical, direct non-medical, and indirect cost. Materials and Methods:The study was conducted at MOH hospitals in Jordan, from August to November 2010. A total of 138 patients and 49 caregivers were involved in the study. An economic evaluation study was used to analyze the burden of hemodialysis treatment at MOH, Jordan. Direct medical costs were estimated through micro and macro costing from the provider′s perspective. Patients′ and caregivers′ costs were included to calculate direct non-medical costs. Human capital approach was employed to evaluate the productivity loss for indirect cost and premature death and potential year life loss was used to estimate the premature death cost. Results: The total burden of hemodialysis at MOH, Jordan was USD17.70 million per year. Cost per session was $72 and the annual cost per patient was $9976. Direct medical cost was $7.20 million (41% and direct non-medical cost was $2.02 million (11%. On the other hand, indirect cost (productivity loss was $8.48 million (48%. All 722 patients on hemodialysis at MOH hospitals consumed 2.7% of MOH budget. Conclusions: Costs of treating and managing patients on hemodialysis at MOH hospitals in Jordan are substantial. Therefore, efforts should be taken to slow down the progress of renal failure to save resources and a comparative study with other modalities, such as continuous ambulatory peritoneal dialysis and kidney transplantation, should be considered.

    The global burden of cancer is escalating as a result of dramatic increases in the use of tobacco in the developing world. The use of tobacco is linked to the development of a broad variety of cancers, mainly lung cancer, the single most common cancer in the world. Tobacco smoking-attributable deaths extends beyond cancer and include stroke, heart attack and COPD. Widening disparities in cancer-related mortality have shifted towards a more dramatic burden in the developing world. Appropriate interventions must be implemented to reduce tobacco use and prevent global mortality that has escalated to epidemic levels. Tobacco control policies, including public health advertisement campaigns, warning labels, adoption of smoke-free laws, comprehensive bans and tax policies are highly effective measures to control tobacco use. Clinicians and academic institutions have to be actively committed to support tobacco control initiatives. The reduction in cancer related morbidity and mortality should be viewed as a global crisis and definitive results will depend on a multilevel effort to effectively reduce the burden of cancer, particularly in underprivileged regions of the world.

    Dengue infections are a significant cause of morbidity and mortality and lead to adverse economic effects in many developing tropical countries. In this study, we estimated the economic burden faced by India during the 2006 dengue epidemic. Costs incurred in managing a cohort of serologically confirmed dengue patients at a tertiary-level private hospital in north India were calculated. The median cost of treatment per hospitalised dengue patient was US$432.2 (95% CI US$343.6-625). A sensitivity analysis was performed to estimate the costs to the health system in India using a regression model. Variables with potentially large variations, including the ratio of unreported to reported cases and of hospitalised to ambulatory cases, the proportion requiring transfusions, loss of economic activities due to loss of workdays and deaths, were used. The average total economic burden was estimated to be US$27.4 million (95% CI US$25.7-29.1 million). Costs in the private heath sector were estimated to be almost four times public sector expenditures. Considerable economic losses (at a macro level) are incurred by developing countries like India during each dengue epidemic. Accurate estimates of the proportions of reported to unreported and of hospitalised to ambulatory dengue cases in India are needed to refine further the estimates of financial burden due to dengue in India.

    Full Text Available Aim. Caregiver burden (CB in epilepsy constitutes an understudied area. Here we attempt to identify the magnitude of this burden, the factors associated with it, and its impact to caregiver quality of life (QOL. Methods. 48 persons with epilepsy (PWE underwent video-EEG monitoring and their caregivers completed questionnaires providing demographic, disease-related, psychiatric, cognitive, sleep, QOL, and burden information. Results. On regression analysis, higher number of antiepileptic drugs, poorer patient neuropsychological performance, lower patient QOL score, and lower caregiver education level were associated with higher CB. Time allocated to patient care approximated but did not attain statistical significance. A moderate inverse correlation between CB and caregiver QOL physical component summary score and a stronger inverse correlation between CB and caregiver QOL mental component summary score were seen. Conclusion. In a selected cohort of PWE undergoing video-EEG monitoring, we identified modest degree of CB, comparable to that reported in the literature for other chronic neurological conditions. It is associated with specific patient and caregiver characteristics and has a negative effect on caregiver QOL.

    Full Text Available Despite accounting for approximately one fifth of all acute gastroenteritis illnesses, norovirus has received comparatively less attention than other infectious pathogens. With several candidate vaccines under development, characterizing the global economic burden of norovirus could help funders, policy makers, public health officials, and product developers determine how much attention and resources to allocate to advancing these technologies to prevent and control norovirus.We developed a computational simulation model to estimate the economic burden of norovirus in every country/area (233 total stratified by WHO region and globally, from the health system and societal perspectives. We considered direct costs of illness (e.g., clinic visits and hospitalization and productivity losses.Globally, norovirus resulted in a total of $4.2 billion (95% UI: $3.2-5.7 billion in direct health system costs and $60.3 billion (95% UI: $44.4-83.4 billion in societal costs per year. Disease amongst children <5 years cost society $39.8 billion, compared to $20.4 billion for all other age groups combined. Costs per norovirus illness varied by both region and age and was highest among adults ≥55 years. Productivity losses represented 84-99% of total costs varying by region. While low and middle income countries and high income countries had similar disease incidence (10,148 vs. 9,935 illness per 100,000 persons, high income countries generated 62% of global health system costs. In sensitivity analysis, the probability of hospitalization had the largest impact on health system cost estimates ($2.8 billion globally, assuming no hospitalization costs, while the probability of missing productive days had the largest impact on societal cost estimates ($35.9 billion globally, with a 25% probability of missing productive days.The total economic burden is greatest in young children but the highest cost per illness is among older age groups in some regions. These large

    Amyloid burden and white matter hyperintensities (WMH) are two common markers of neurodegeneration present in advanced aging. Each represents a potential early indicator of an age-related neurological disorder that impacts cognition. The presence of amyloid is observed in a substantial subset of cognitively normal older adults, but the literature remains equivocal regarding whether amyloid in nondemented populations is deleterious to cognition. Similarly, WMH are detected in many nondemented older adults and there is a body of evidence indicating that WMH are associated with decreased executive function and other cognitive domains. The current study investigated amyloid burden and WMH in clinically normal older adult humans aged 65 to 86 (N=168) and examined each biomarker’s relation with cognitive domains of episodic memory, executive function, and speed of processing. Factors for each domain were derived from a neuropsychological battery on a theoretical basis without reference to the relation between cognition and the biomarkers. Amyloid burden and WMH were not correlated with one another. Age was associated with lower performance in all cognitive domains, while higher estimated verbal intelligence was associated with higher performance in all domains. Hypothesis-driven tests revealed that amyloid burden and WMH had distinct cognitive profiles, with amyloid burden having a specific influence on episodic memory and WMH being primarily associated with executive function but having broad (but lesser) effects on the other domains. These findings suggest that even prior to clinical impairment, amyloid burden and WMH likely represent neuropathological cascades with distinct etiologies and dissociable influences on cognition.

    Full Text Available Ivan P Artyukhov,1 Irina L Arshukova,2 Elena A Dobretsova,2 Andrey V Shulmin2 1Department of Health Care Management, 2Department of Public Health and Health Care, Krasnoyarsk State Medical University, Krasnoyarsk, Russia Background: This study assesses mortality and economic burden due to the regular tobacco usage among the population of the Krasnoyarsk region of the Russian Federation. This territory was chosen for the analysis because of two factors: high smoking prevalence in the Krasnoyarsk region (46% among the adult population and premature mortality of the working-age population, which leads to a significant burden to the federal budget of the Russian Federation. Data sources: In our work, three main causes of smoking-related deaths were considered: cardiovascular disease, lung cancer, and COPD. The working-age population was investigated (20–72 years old. The databases of mortality and population size of the territorial body of state statistics of the Krasnoyarsk region (data for 2013 were used as the information sources. Methods: Joint application of population-attributable risk and disability-adjusted life years method allowed us to estimate medico-demographic and economic burden due to the tobacco-attributable premature mortality in the investigated population. Results: We found that tobacco use-related economic burden is at least equal to 2% of the gross regional product of the Krasnoyarsk region in 2013. Conclusion: An assessment of economic tobacco use-related burden is important for determining the volume of necessary funding for development of smoking prevention programs, proper estimation of tobacco companies’ taxation, and other measures for controlling tobacco use. Smoking cessation is a priority for prevention of the tobacco-related diseases and reduction of their burden on local economy.

    1998-01-01

    Full Text Available Economic analysis is one way to determine the allocation of scarce resources for health-care programs. The initial step in this process is to estimate in economic terms the burden of diseases and the benefit from interventions for prevention and treatment of these diseases. In this paper, the direct and indirect economic loss due to blindness in India is calculated on the basis of certain assumptions. The cost of treating cataract blindness in India is estimated at current prices. The economic burden of blindness in India for the year 1997 based on our assumptions is Rs. 159 billion (US$ 4.4 billion, and the cumulative loss over lifetime of the blind is Rs. 2,787 billion (US$ 77.4 billion. Childhood blindness accounts for 28.7% of this lifetime loss. The cost of treating all cases of cataract blindness in India is Rs. 5.3 billion (US$ 0.15 billion. Similar estimates for causes of blindness other than cataract have to be made in order to develop a comprehensive approach to deal with blindness in India.

    As a result of an epidemiological transition from communicable to non-communicable diseases for last few decades, cardiovascular diseases (CVD) are being considered as an important cause of mortality and morbidity in many developing countries including Bangladesh. Performing an extensive literature search, we compiled, summarized, and categorized the existing information about CVD mortality and morbidity among different clusters of Bangladeshi population. The present review reports that the burden of CVD in terms of mortality and morbidity is on the rise in Bangladesh. Despite a few non-communicable disease prevention and control programs currently running in Bangladesh, there is an urgent need for well-coordinated national intervention strategies and public health actions to minimize the CVD burden in Bangladesh. As the main challenge for CVD control in a developing country is unavailability of adequate epidemiological data related to various CVD events, the present review attempted to accumulate such data in the current context of Bangladesh. This may be of interest to all stakeholder groups working for CVD prevention and control across the country and globe. PMID:26686566

  19. NIH disease funding levels and burden of disease.

    Directory of Open Access Journals (Sweden)

    Leslie A Gillum

    Full Text Available BACKGROUND: An analysis of NIH funding in 1996 found that the strongest predictor of funding, disability-adjusted life-years (DALYs, explained only 39% of the variance in funding. In 1998, Congress requested that the Institute of Medicine (IOM evaluate priority-setting criteria for NIH funding; the IOM recommended greater consideration of disease burden. We examined whether the association between current burden and funding has changed since that time. METHODS: We analyzed public data on 2006 NIH funding for 29 common conditions. Measures of US disease burden in 2004 were obtained from the World Health Organization's Global Burden of Disease study and national databases. We assessed the relationship between disease burden and NIH funding dollars in univariate and multivariable log-linear models that evaluated all measures of disease burden. Sensitivity analyses examined associations with future US burden, current and future measures of world disease burden, and a newly standardized NIH accounting method. RESULTS: In univariate and multivariable analyses, disease-specific NIH funding levels increased with burden of disease measured in DALYs (p = 0.001, which accounted for 33% of funding level variation. No other factor predicted funding in multivariable models. Conditions receiving the most funding greater than expected based on disease burden were AIDS ($2474 M, diabetes mellitus ($390 M, and perinatal conditions ($297 M. Depression ($719 M, injuries ($691 M, and chronic obstructive pulmonary disease ($613 M were the most underfunded. Results were similar using estimates of future US burden, current and future world disease burden, and alternate NIH accounting methods. CONCLUSIONS: Current levels of NIH disease-specific research funding correlate modestly with US disease burden, and correlation has not improved in the last decade.

    Full Text Available The disease burden of rural Indian women is reviewed by utilizing the data from the 'Survey of Causes of Death (rural' annual reports of Registrar General of India supplemented with National family health survey (NFHS-II. The review indicates that bronchitis and asthma are the leading causes while prematurity and heart attacks are second and third respectively. Most of the maternal deaths are concentrated in the age group 20-24 and bleeding is the main cause of maternal death. Tuberculosis of the lungs, malaria and burns are also important causes of death in the early reproductive ages. Rate of suicide, burn, and anaemia diminishes with age. Though nationwide health plans have succeeded in reducing the fatality of women's diseases to a entrain extent, there is however, a great need for improved and effective area-specific health programs to achieve the desired goals.

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

  4. Beyond Attributable Burden: Estimating the Avoidable Burden of Disease Associated with Household Air Pollution.

    Directory of Open Access Journals (Sweden)

    Randall Kuhn

    Full Text Available The Global Burden of Disease (GBD studies have transformed global understanding of health risks by producing comprehensive estimates of attributable disease burden, or the current disease that would be eliminated if a risk factor did not exist. Yet many have noted the greater policy significance of avoidable burden, or the future disease that could actually be eliminated if a risk factor were eliminated today. Avoidable risk may be considerably lower than attributable risk if baseline levels of exposure or disease are declining, or if a risk factor carries lagged effects on disease. As global efforts to deliver clean cookstoves accelerate, a temporal estimation of avoidable risk due to household air pollution (HAP becomes increasingly important, particularly in light of the rapid uptake of modern stoves and ongoing epidemiologic transitions in regions like South and Southeast Asia.We estimate the avoidable burden associated with HAP using International Futures (IFs, an integrated forecasting system that has been used to model future global disease burdens and risk factors. Building on GBD and other estimates, we integrated a detailed HAP exposure estimation and exposure-response model into IFs. We then conducted a counterfactual experiment in which HAP exposure is reduced to theoretical minimum levels in 2015. We evaluated avoidable mortality and DALY reductions for the years 2015 to 2024 relative to a Base Case scenario in which only endogenous changes occurred. We present results by cause and region, looking at impacts on acute lower respiratory infection (ALRI and four noncommunicable diseases (NCDs. We found that just 2.6% of global DALYs would be averted between 2015 and 2024, compared to 4.5% of global DALYs attributed to HAP in the 2010 GBD study, due in large part to the endogenous tendency towards declining traditional stove usage in the IFs base case forecast. The extent of diminished impact was comparable for ALRI and affected NCDs

    Colin D Mathers

    Full Text Available Reliable, comparable information about the main causes of disease and injury in populations, and how these are changing, is a critical input for debates about priorities in the health sector. Traditional sources of information about the descriptive epidemiology of diseases, injuries, and risk factors are generally incomplete, fragmented, and of uncertain reliability and comparability. The Global Burden of Disease (GBD study has provided a conceptual and methodological framework to quantify and compare the health of populations using a summary measure of both mortality and disability, the disability-adjusted life year (DALY.This paper describes key features of the Global Burden of Disease analytic approach, which provides a standardized measurement framework to permit comparisons across diseases and injuries, as well as risk factors, and a systematic approach to the evaluation of data. The paper describes the evolution of the GBD, starting from the first study for the year 1990, summarizes the methodological improvements incorporated into GBD revisions for the years 2000-2004 carried out by the World Health Organization, and examines priorities and issues for the next major GBD study, funded by the Bill & Melinda Gates Foundation, and commencing in 2007.The paper presents an overview of summary results from the Global Burden of Disease study 2002, with a particular focus on the neglected tropical diseases, and also an overview of the comparative risk assessment for 26 global risk factors. Taken together, trypanosomiasis, Chagas disease, schistosomiasis, leishmaniasis, lymphatic filariasis, onchocerciasis, intestinal nematode infections, Japanese encephalitis, dengue, and leprosy accounted for an estimated 177,000 deaths worldwide in 2002, mostly in sub-Saharan Africa, and about 20 million DALYs, or 1.3% of the global burden of disease and injuries. Further research is currently underway to revise and update these estimates.

    Rianne M Blom

    Full Text Available INTRODUCTION: Body Integrity Identity Disorder (BIID is a rare, infrequently studied and highly secretive condition in which there is a mismatch between the mental body image and the physical body. Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. METHODS: Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. RESULTS: Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification. CONCLUSIONS: The amputation variant and paralyzation variant of BIID are to be considered as one of the same condition. Amputation of the healthy body part appears to result in remission of BIID and an impressive improvement of quality of life. Knowledge of and respect for the desires of BIID individuals are the first steps in providing care and may decrease the huge burden they experience.

    2015-10-01

    Serious fungal infections (SFIs) could be more frequent than are recognised. Estimates of the incidence and prevalence of SFIs are essential in order to identify public health problems. We estimated the rates of SFIs in Mexico, following a methodology similar to that used in prior studies. We obtained information about the general population and populations at risk. A systematic literature search was undertaken to identify epidemiological reports of SFIs in Mexico. When Mexican reports were unavailable, we based our estimates on international literature. The most prevalent SFIs in Mexico are recurrent vulvovaginal candidiasis (5999 per 100,000) followed by allergic bronchopulmonary aspergillosis (60 per 100,000), chronic pulmonary aspergillosis (15.9 per 100,000), fungal keratitis (10.4 per 100,000), invasive candidiasis (8.6 per 100,000) and SFIs in HIV (8.2 per 100,000); coccidioidomycosis (7.6 per 100,000), IA (4.56 per 100,000). These correspond to 2,749,159 people affected in any year (2.45% of the population), probably >10,000 deaths and 7000 blind eyes. SFIs affect immunocompromised and healthy populations. Most are associated with high morbidity and mortality rates. Validation of these estimates with epidemiological studies is required. The burdens indicate that an urgent need to improve medical skills, surveillance, diagnosis, and management of SFIs exists. PMID:26449505

  13. History and Global Burden of Viral Hepatitis.

    Blum, Hubert E

    2016-01-01

    Between 1963 and 1989, 5 hepatotropic viruses have been discovered that are the major causes of viral hepatitides worldwide: hepatitis A virus, hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis delta virus and hepatitis E virus. Their epidemiology and pathogenesis have been studied in great detail. Furthermore, the structure and genetic organization of their DNA or RNA genome including the viral life cycle have been elucidated and have been successfully translated into important clinical applications, such as the specific diagnosis, therapy and prevention of the associated liver diseases, including liver cirrhosis and hepatocellular carcinoma (HCC). The prevalence of acute and chronic viral hepatitis A-E shows distinct geographic differences. The global burden of disease (prevalence, incidence, death, disability-adjusted life years) has been analyzed in seminal studies that show that the worldwide prevalence of hepatitis A-E has significantly decreased between 1990 and 2013. During the same time, the incidence of HBV-related liver cirrhosis and HCC, respectively, also decreased or increased slightly, the incidence of the HCV-related liver cirrhosis remained stable and the incidence of HCV-related HCC showed a major increase. During the coming years, we expect to improve our ability to prevent and effectively treat viral hepatitis A-E, resulting in the control of these global infections and the elimination of their associated morbidities and mortalities.

    Full Text Available To assess the risk of hepatitis C in Canada and to predict the burden that this disease may pose to the Canadian society in the near future, expected numbers of persons at different stages of the disease currently and in the next decade were estimated by simulation using a published hepatitis C natural history model with no treatment effect being applied. Based on the estimate of 240,000 persons who are currently infected with the hepatitis C virus in Canada, the simulation analysis demonstrated that the number of hepatitis C cirrhosis cases would likely increase by 92% from 1998 to the year 2008. It was also projected that the number of liver failures and hepatocellular carcinomas related to hepatitis C would increase by 126% and 102%, respectively, in the next decade. The number of liver-related deaths associated with hepatitis C is expected to increase by 126% in 10 years. The medical and social care systems in Canada may not be ready to support these large increases. These results highlight the importance of both the control of disease progression of hepatitis C virus-infected persons and the primary prevention of hepatitis C infections in Canada.

    Full Text Available PURPOSE: PEGylated liposomes are important drug carriers that can passively target tumor by enhanced permeability and retention (EPR effect in neoplasm lesions. This study demonstrated that tumor burden determines the tumor uptake, and also the tumor response, in cancer treatment with PEGylated liposomal drugs in a C26/tk-luc colon carcinoma-bearing mouse model. METHODS: Empty PEGylated liposomes (NanoX and those encapsulated with VNB (NanoVNB were labeled with In-111 to obtain InNanoX and InVNBL in high labeling yield and radiochemical purity (all >90%. BALB/c mice bearing either small (58.4±8.0 mm(3 or large (102.4±22.0 mm(3 C26/tk-luc tumors in the right dorsal flank were intravenously administered with NanoVNB, InNanoX, InVNBL, or NanoX as a control, every 7 days for 3 times. The therapeutic efficacy was evaluated by body weight loss, tumor growth inhibition (using calipers and bioluminescence imaging and survival fraction. The scintigraphic imaging of tumor mouse was performed during and after treatment. RESULTS: The biodistribution study of InVNBL revealed a clear inverse correlation (r (2 = 0.9336 between the tumor uptake and the tumor mass ranged from 27.6 to 623.9 mg. All three liposomal drugs showed better therapeutic efficacy in small-tumor mice than in large-tumor mice. Tumor-bearing mice treated with InVNBL (a combination drug showed the highest tumor growth inhibition rate and survival fraction compared to those treated with NanoVNB (chemodrug only and InNanoX (radionuclide only. Specific tumor targeting and significantly increased tumor uptake after periodical treatment with InVNBL were evidenced by scintigraphic imaging, especially in mice bearing small tumors. CONCLUSION: The significant differences in the outcomes of cancer treatment and molecular imaging between animals bearing small and large tumors revealed that tumor burden is a critical and discriminative factor in cancer therapy using PEGylated liposomal drugs.

    Full Text Available BACKGROUND: Rates of diseases and injuries and the effects of their risk factors can have substantial subnational heterogeneity, especially in middle-income countries like Mexico. Subnational analysis of the burden of diseases, injuries, and risk factors can improve characterization of the epidemiological transition and identify policy priorities. METHODS AND FINDINGS: We estimated deaths and loss of healthy life years (measured in disability-adjusted life years [DALYs] in 2004 from a comprehensive list of diseases and injuries, and 16 major risk factors, by sex and age for Mexico and its states. Data sources included the vital statistics, national censuses, health examination surveys, and published epidemiological studies. Mortality statistics were adjusted for underreporting, misreporting of age at death, and for misclassification and incomparability of cause-of-death assignment. Nationally, noncommunicable diseases caused 75% of total deaths and 68% of total DALYs, with another 14% of deaths and 18% of DALYs caused by undernutrition and communicable, maternal, and perinatal diseases. The leading causes of death were ischemic heart disease, diabetes mellitus, cerebrovascular disease, liver cirrhosis, and road traffic injuries. High body mass index, high blood glucose, and alcohol use were the leading risk factors for disease burden, causing 5.1%, 5.0%, and 7.3% of total burden of disease, respectively. Mexico City had the lowest mortality rates (4.2 per 1,000 and the Southern region the highest (5.0 per 1,000; under-five mortality in the Southern region was nearly twice that of Mexico City. In the Southern region undernutrition and communicable, maternal, and perinatal diseases caused 23% of DALYs; in Chiapas, they caused 29% of DALYs. At the same time, the absolute rates of noncommunicable disease and injury burdens were highest in the Southern region (105 DALYs per 1,000 population versus 97 nationally for noncommunicable diseases; 22 versus

    2015-11-01

    Interpretation: Patients with culture confirmed tuberculous pericarditis have a high bacillary burden, and this bacterial burden drives mortality. Thus proven tuberculosis pericarditis is not a paucibacillary disease. Moreover, the severe immunosuppression suggests limited inflammation. There is a need for the design of a highly bactericidal regimen for this condition.

    2002-08-01

    This longitudinal study explored changes in perceived burden among Taiwanese family caregivers (n=77) from nursing home placement of an elder to four months postadmission. Higher burden at placement was related to the level of dependence of the care recipients (p=0.004), or caregiver's poor health (p<0.01). After nursing home placement for four months, global burden decreased (p<0.01) contributed primarily by lessened burden in three sub-scales: lack of family support, impact of schedule and impact of health. Burden scores on caregiver esteem and impact of finances were not decreased after placement. Duration of caregiving was the only demographic factor predicting change in global burden (p<0.001). Changes in impact on finances, and impact on health were, respectively, predicted by the perceived health (p=0.005), and religious preference (p=0.01). These results provide valuable information to healthcare providers for an understanding of the changes of caregiving burden after nursing home placement and the correlates of these changes, which may help devise an appropriate policy for alleviating the caregiver's burden.

However, despite this literature, fewer studies have focused on the burden of insomnia among patients in Japan. The objective of the current study is to extend this work in Japan to further understand the effect of insomnia on health-related quality of life (hrQOL. Further, another objective is to understand general predictors of hrQOL among patients with insomnia. Methods: Data from the 2012 Japan National Health and Wellness Survey, an annual, cross-sectional study of adults aged 18 years or older, were used (N=30,000. All National Health and Wellness Survey respondents were categorized based on the incidence of self-reported insomnia diagnosis and prescription medication usage (clinical insomniacs under treatment versus [vs] good sleepers without insomnia or insomnia symptoms. Comparisons among different groups were made using multiple regression models controlling for demographics and health history. Results: Clinical insomniacs (n=1,018; 3.4% reported significantly worse hrQOL compared with good sleepers (n=20,542 (mental component summary: 34.2 vs 48.0; physical component summary: 48.0 vs 52.8; health utilities: 0.61 vs 0.76; all P<0.05.

    A sound knowledge base is required to target resources to reduce workplace exposure to carcinogens. This project aimed to provide an objective estimate of the burden of cancer in Britain due to occupation. This volume presents extensive analyses for all carcinogens and occupational circumstances defined as definite or probable human occupational carcinogens by the International Agency for Research on Cancer. This article outlines the structure of the supplement - two methodological papers (statistical approach and exposure assessment), eight papers presenting the cancer-specific results grouped by broad anatomical site, a paper giving industry sector results and one discussing work-related cancer-prevention strategies. A brief summary of the methods and an overview of the updated overall results are given in this introductory paper. A general discussion of the overall strengths and limitations of the study is also presented. Overall, 8010 (5.3%) total cancer deaths in Britain and 13,598 cancer registrations were attributable to occupation in 2005 and 2004, respectively. The importance of cancer sites such as mesothelioma, sinonasal, lung, nasopharynx, breast, non-melanoma skin cancer, bladder, oesophagus, soft tissue sarcoma and stomach cancers are highlighted, as are carcinogens such as asbestos, mineral oils, solar radiation, silica, diesel engine exhaust, coal tars and pitches, dioxins, environmental tobacco smoke, radon, tetrachloroethylene, arsenic and strong inorganic mists, as well as occupational circumstances such as shift work and occupation as a painter or welder. The methods developed for this project are being adapted by other countries and extended to include social and economic impact evaluation. PMID:22710676

    Full Text Available Background: Incinerator workers are not considered to have arsenic overexposure although they have the risk of overexposure to other heavy metals. Aim: To examine the relationship between arsenic burden and risk of occupational exposure in employees working at a municipal refuse incinerator by determining the concentrations of arsenic in the blood and urine. Settings and Design: The workers were divided into three groups based on their probability of contact with combustion-generated residues, namely Group 1: indirect contact, Group 2: direct contact and Group 3: no contact. Healthy age- and sex-matched residents living in the vicinity were enrolled as the control group. Materials and Methods: Heavy metal concentrations were measured by atomic absorption spectrophotometer. Downstream rivers and drinking water of the residents were examined for environmental arsenic pollution. A questionnaire survey concerning the contact history of arsenic was simultaneously conducted. Statistical analysis: Non-parametric tests, cross-tabulation and multinomial logistic regression. Results: This study recruited 122 incinerator workers. The urine and blood arsenic concentrations as well as incidences of overexposure were significantly higher in the workers than in control subjects. The workers who had indirect or no contact with combustion-generated residues had significantly higher blood arsenic level. Arsenic contact history could not explain the difference. Airborne and waterborne arsenic pollution were not detected. Conclusion: Incinerator workers run the risk of being exposed to arsenic pollution, especially those who have incomplete protection in the workplace even though they only have indirect or no contact with combustion-generated pollutants.

    Objective Chronic obstructive pulmonary disease (COPD) is a very prevalent and invalidating disease. The aim of this study was to analyze the burden borne by informal caregivers of patients with COPD. Methods We used the Survey on Disabilities, Personal Autonomy, and Dependency Situations (Encuesta sobre Discapacidad, Autonomía personal y Situaciones de Dependencia [EDAD]-2008) to obtain information on the characteristics of disabled individuals with COPD and their caregivers in Spain. Additionally, statistical multivariate analyses were performed to analyze the impact that an increase in dependence would have on the problems for which caregivers provide support, in terms of health, professional, and leisure/social dimensions. Results A total of 461,884 individuals with one or more disabilities and with COPD were identified, and 220,892 informal caregivers were estimated. Results showed that 35% of informal caregivers had health-related problems due to the caregiving provided; 83% had leisure/social-related problems; and among caregivers of working age, 38% recognized having profession-related problems. The probability of a problem arising was significantly associated with the degree of dependence of the patient receiving care. Caregivers of patients with great dependence showed a 39% higher probability of presenting health-related problems, 27% more professional problems, and 23% more leisure problems compared with those with nondependent patients. Conclusion The results show the large impact on society in terms of the welfare of informal caregivers of patients with COPD. A higher level of dependence was associated with more severe problems in caregivers, in all dimensions. PMID:25709429

    Caregivers of individuals with chronic obstructive pulmonary disease (COPD) experience significant burden. To develop effective interventions to support this vulnerable group, it is necessary to understand how this burden varies as a function of patient well-being and across the illness trajectory. This systematic review aimed to identify the number and type of data-based publications exploring the burden and unmet needs of caregivers of individuals with COPD. Medline, Embase, PsycINFO and Cochrane databases were searched for studies published between January 2000 and February 2014. Studies were eligible if they were quantitative studies examining unmet needs of, or burden on, adult caregivers of individuals with COPD. Eligible papers were categorised according to (i) type (i.e. descriptive, measurement and intervention studies); (ii) whether they measured associations between patient and caregiver burden and (iii) whether they measured caregiver burden longitudinally. Twenty-seven data-based papers met criteria for inclusion. There was a significant increase in the total number of publications over time. The majority of publications were descriptive studies (n = 25), with one measurement and one intervention study identified. Fourteen descriptive studies measured the relationship between patient or caregiver factors and caregiver burden. Only two studies measured caregiver burden over time. There are a number of gaps in the body of research examining burden and unmet needs of caregivers of individuals with COPD that preclude the development of effective interventions for this population. Greater research effort should be directed towards identifying rigorous measurement tools which more accurately characterise caregiver burden, so that evidence-based interventions can be developed.

    Objective To examine the unique contribution of social support to burden in caregivers of adults aging with spinal cord injuries (SCI). Design Secondary analyses of cross-sectional data from a large cohort of adults aging with SCI and their primary caregivers. Setting Multiple community locations in Pittsburgh, PA, and Miami, FL. Participants Caregivers of community-dwelling adults aging with SCI (n=173) were interviewed as part of a multisite randomized clinical trial. The mean age of caregivers was 53 years (SD=15) and of care-recipients 55 years (SD=13). Interventions Not applicable. Main Outcome Measures The primary outcome was caregiver burden measured with the Abridged Version of the Zarit Burden Interview. A hierarchical multiple regression analysis examined social supports (social integration, received social support, and negative social interactions) effect on burden in caregivers of adults aging while controlling for demographic characteristics and caregiving characteristics. Results After controlling for demographic characteristics and caregiving characteristics, social integration (β̂ =−.16, P<.05), received social support (β̂ =−.15, P<.05), and negative social interactions (β̂ =.21, P<.01) were significant independent predictors of caregiver burden. Conclusions Findings demonstrate that social support is an important factor associated with burden in caregivers of adults aging with SCI. Social support should be considered for assessments and interventions designed to identify and reduce caregiver burden. PMID:22824248

  14. Asymmetries of poverty: why global burden of disease valuations underestimate the burden of neglected tropical diseases.

    Directory of Open Access Journals (Sweden)

    Charles H King

    Full Text Available The disability-adjusted life year (DALY initially appeared attractive as a health metric in the Global Burden of Disease (GBD program, as it purports to be a comprehensive health assessment that encompassed premature mortality, morbidity, impairment, and disability. It was originally thought that the DALY would be useful in policy settings, reflecting normative valuations as a standardized unit of ill health. However, the design of the DALY and its use in policy estimates contain inherent flaws that result in systematic undervaluation of the importance of chronic diseases, such as many of the neglected tropical diseases (NTDs, in world health. The conceptual design of the DALY comes out of a perspective largely focused on the individual risk rather than the ecology of disease, thus failing to acknowledge the implications of context on the burden of disease for the poor. It is nonrepresentative of the impact of poverty on disability, which results in the significant underestimation of disability weights for chronic diseases such as the NTDs. Finally, the application of the DALY in policy estimates does not account for the nonlinear effects of poverty in the cost-utility analysis of disease control, effectively discounting the utility of comprehensively treating NTDs. The present DALY framework needs to be substantially revised if the GBD is to become a valid and useful system for determining health priorities.

    Background In Indonesia, coronary heart disease (CHD) and stroke are estimated to cause more than 470 000 deaths annually. In order to inform primary prevention policies, we estimated the sex- and age-specific burden of CHD and stroke attributable to five major and modifiable vascular risk factors: cigarette smoking, hypertension, diabetes, elevated total cholesterol, and excess body weight. Methods Population attributable risks for CHD and stroke attributable to these risk factors individually were calculated using summary statistics obtained for prevalence of each risk factor specific to sex and to two age categories (Indonesian population.

    2013-11-01

    Full Text Available BACKGROUND: Depressive disorders were a leading cause of burden in the Global Burden of Disease (GBD 1990 and 2000 studies. Here, we analyze the burden of depressive disorders in GBD 2010 and present severity proportions, burden by country, region, age, sex, and year, as well as burden of depressive disorders as a risk factor for suicide and ischemic heart disease. METHODS AND FINDINGS: Burden was calculated for major depressive disorder (MDD and dysthymia. A systematic review of epidemiological data was conducted. The data were pooled using a Bayesian meta-regression. Disability weights from population survey data quantified the severity of health loss from depressive disorders. These weights were used to calculate years lived with disability (YLDs and disability adjusted life years (DALYs. Separate DALYs were estimated for suicide and ischemic heart disease attributable to depressive disorders. Depressive disorders were the second leading cause of YLDs in 2010. MDD accounted for 8.2% (5.9%-10.8% of global YLDs and dysthymia for 1.4% (0.9%-2.0%. Depressive disorders were a leading cause of DALYs even though no mortality was attributed to them as the underlying cause. MDD accounted for 2.5% (1.9%-3.2% of global DALYs and dysthymia for 0.5% (0.3%-0.6%. There was more regional variation in burden for MDD than for dysthymia; with higher estimates in females, and adults of working age. Whilst burden increased by 37.5% between 1990 and 2010, this was due to population growth and ageing. MDD explained 16 million suicide DALYs and almost 4 million ischemic heart disease DALYs. This attributable burden would increase the overall burden of depressive disorders from 3.0% (2.2%-3.8% to 3.8% (3.0%-4.7% of global DALYs. CONCLUSIONS: GBD 2010 identified depressive disorders as a leading cause of burden. MDD was also a contributor of burden allocated to suicide and ischemic heart disease. These findings emphasize the importance of including depressive

    Full Text Available Objective: The objective of the present study was to identify households in which overweight and underweight coexisted (dual burden of malnutrition and explore the factors that could be contributing to the dual burden of malnutrition at the household level in this population. Study design: Cross-sectional nutritional survey. Methods: After applying the exclusion criteria, 136 households were included. Mothers were classified as normal weight or overweight/obese based on body mass index (BMI cut-off points and children and adolescents were classified as stunted or not based on height-for-age z-score. Households with an obese mother and a stunted children or adolescent were categorized as dual burden households. Results: The prevalence of dual burden household was 12%. Compared with other households, dual burden households tended to have more people living in the house, and the educational level of the head of household was lower. Individuals living in dual burden households showed overall lower energy intakes and were more likely to have inadequate intakes of calcium and iron. Conclusions: The nutrition transition in this community might be one of the leading causes of the observed dual burden of malnutrition. The results presented here indicate the need to consider whether programs that focus on only one type of nutritional problem come might actually exacerbate the other.

    Full Text Available Double burden of malnutrition, characterised by undernutrition among poor children and obesity among deprived adults, is a serious global problem and an important promoter of ‘double burden of disease’ which is currently affecting low– and middle–income countries. Possible ways to reduce this burden is through education on the importance of equilibrium between energy intake and expenditure; ensuring conditions for optimal fetal and early child development; and reducing poverty as one of the main drivers of both undernutrition and obesity, through empowering local communities.

    Family caregivers of older adults frequently experience feelings of burden and depression though they may not come to the attention to health and service providers until they are at a point of crisis. Through a simple screening tool, the Maine Primary Partners in Caring (MPPC) project identified individuals providing care to older adults through rural primary care practices, in order to provide upstream interventions before caregivers were in crisis. This paper describes a sample (n=62) of rural family caregivers identified through their physicians' offices. High levels of caregiver burden and depression were reported. Family support and knowledge of caregiver tasks predicted decreased caregiver burden and depression, while isolation predicted increased caregiver burden. Implications of these results for gerontological social workers are outlined.

  7. Renewable energy burden sharing. REBUS. Manual for the REBUS model

    International Nuclear Information System (INIS)

    The REBUS model quantifies the effects of implementing renewable electricity targets, and the impact of introducing burden sharing systems within the EU, such as a Tradable Green Certificate (TGC) system. Results are obtained for a range of so-called burden sharing options that reflect differences in economic, social and geographical possibilities to increase the share of renewables in individual geographical regions. The REBUS model furthermore analyses the impact of other supporting mechanisms for renewable electricity on the effects of a burden sharing mechanism. With this, the REBUS model is a framework that can be used for quantifying the most equitable distribution of costs (burden sharing) and compare consequences of different equity criteria. Therewith it aims to support key policy makers, industrial stakeholders and consumers in making decisions on the possibilities to achieve their joint RES-E targets

    The aim of this study is to describe the characteristics of caregivers of chronic hemodialysis patients, assess their perceived burden and health-related quality of life, and investigate factors influencing this burden. We studied 100 hemodialysis patients and their respective primary caregivers for more than 4 months, measuring quality of life by the Medical Outcomes Survey 36-Item Short-Form Health Survey (SF-36). Subjective burden on caregivers was assessed by the Caregiver Burden scale (score range, 1 to 4; higher values indicate a greater effect). The majority of caregivers were women (84%), married (66%), with a mean age of 46 +/- 2 (SE) years, and of low socioeconomic level. Their main types of relationship with patients were wives (38%) and sons or daughters (27%). Caregiver Mental Health and Vitality were the most affected emotional dimensions on the SF-36 (mean scores, 64.4 +/- 1.8 and 66.6 +/- 1.7, respectively). Mean score of total burden experienced was 2.07 +/- 0.05. Multiple regression analysis showed that independent and significant predictors of burden were Mental Health of the caregiver (R2 = 24%), Vitality of the patient (R2 = 10%), type of relationship of the caregiver (female spouse) (R2 = 5%), and Pain of the caregiver (R2 = 3%). Caregivers of hemodialysis patients may experience a significant burden and an adverse effect on their quality of life. Emotional aspects of caregivers (particularly female spouses) and patients are important predictors of burden. Social support and psychological interventions should be considered to improve caregiver life and patient outcomes. PMID:11920347

  16. Estimating the true global burden of mental illness.

    Science.gov (United States)

    Vigo, Daniel; Thornicroft, Graham; Atun, Rifat

    2016-02-01

    We argue that the global burden of mental illness is underestimated and examine the reasons for under-estimation to identify five main causes: overlap between psychiatric and neurological disorders; the grouping of suicide and self-harm as a separate category; conflation of all chronic pain syndromes with musculoskeletal disorders; exclusion of personality disorders from disease burden calculations; and inadequate consideration of the contribution of severe mental illness to mortality from associated causes. Using published data, we estimate the disease burden for mental illness to show that the global burden of mental illness accounts for 32·4% of years lived with disability (YLDs) and 13·0% of disability-adjusted life-years (DALYs), instead of the earlier estimates suggesting 21·2% of YLDs and 7·1% of DALYs. Currently used approaches underestimate the burden of mental illness by more than a third. Our estimates place mental illness a distant first in global burden of disease in terms of YLDs, and level with cardiovascular and circulatory diseases in terms of DALYs. The unacceptable apathy of governments and funders of global health must be overcome to mitigate the human, social, and economic costs of mental illness.

    Focusing on the understudied, increasing population of male Alzheimer's disease (AD) caregivers, the purpose of this study was to identify their likelihood of utilizing 3 coping strategies (task focused, emotion focused, and avoidance focused) and to examine the effects of each coping strategy on caregiving burden. Data were collected from 138 male AD caregivers in southern United States, including geographically proportional representation of African Americans in the sample. Stepwise regression revealed effects of each coping strategy on caregiving burden, controlling for demographics. The sample reported high burden. Task focused was the highest reported coping strategy. Yet, regression models indicated no significant effect of task-focused coping on burden outcomes. Emotion-focused and avoidance-focused coping each showed significant proportional effects on burden. Implications suggest that emotion- and avoidance-focused coping among male AD caregivers may be maladaptive, that is, reinforcing burden. Male AD caregivers may benefit from more task-focused coping, such as planning and active problem solving. PMID:25267930

    Despite gains in controlling mortality relating to diarrhoeal disease, the burden of disease remains unacceptably high. To refocus health research to target disease-burden reduction as the goal of research in child health, the Child Health and Nutrition Research Initiative developed a systematic strategy to rank health research options. This priority-setting exercise included listing of 46 competitive research options in diarrhoeal disease and their critical and quantitative appraisal by 10 experts based on five criteria for research that reflect the ability of the research to be translated into interventions and achieved disease-burden reduction. These criteria included the answerability of the research questions; the efficacy and effectiveness of the intervention resulting from the research; the maximal potential for disease-burden reduction of the interventions derived from the research; the affordability, deliverability, and sustainability of the intervention supported by the research; and the overall effect of the research-derived intervention on equity. Experts scored each research option independently to delineate the best investments for diarrhoeal disease control in the developing world to reduce the burden of disease by 2015. Priority scores obtained for health policy and systems research obtained eight of the top 10 rankings in overall scores, indicating that current investments in health research are significantly different from those estimated to be the most effective in reducing the global burden of diarrhoeal disease by 2015.

    2009-01-01

    In this paper we present a brief measure of caregiver burden, the Mood Disorder Burden Index (MDBI), for use with family members and close friends of adults with major depressive disorder (MDD) or bipolar disorder (BD). The MDBI assesses burden in three core domains (patients’ mood symptoms, caregivers’ worry about the future, and caregivers’ interpersonal difficulties with the patient) and includes an optional module that assesses caregiver burden associated with patients’ pharmacotherapy or psychotherapy. The MDBI was administered to caregivers of older individuals (i.e., 58 years and older) with MDD (n = 123) or BD (n = 38 who were receiving treatment through a research study. Analyses indicated evidence of convergent and discriminant validity of the new measure well as internal consistency within both caregiver groups. It will be important for future research to administer the MDBI to caregivers of middle-aged and older patients as well as those receiving treatment through inpatient settings or community outpatient clinics.

    The dissection course (here abbreviated: PK) is still an obligatory part of medical schools in Germany. In this study we investigated the experiences and burdens of medical students in gross anatomy, especially "distancing from the human body".This study was carried out three times with the self-composed questionnaire BF-PK: before, while and after PK. In total 371 students participated in the PK. 297 students participated at measurement 1. In advance 25-30% of the medical students reported anxiety and emotional inhibition, during the course only 7-10%. The coping strategy "distancing from the human body" was prominent. Anxiety, emotional inhibition and disgust remained for 5-10% of the participants.The gross anatomy course causes emotional stress for a considerable amount of medical students. For those students that were not able to overcome the mental stress themselves service offers should be implemented. PMID:23468367

    Avoiding food loss and waste may counteract the increasing food demand and reduce greenhouse gas (GHG) emissions from the agricultural sector. This is crucial because of limited options available to increase food production. In the year 2010, food availability was 20% higher than was required on a global scale. Thus, a more sustainable food production and adjusted consumption would have positive environmental effects. This study provides a systematic approach to estimate consumer level food waste on a country scale and globally, based on food availability and requirements. The food requirement estimation considers demographic development, body weights, and physical activity levels. Surplus between food availability and requirements of a given country is considered as food waste. The global food requirement changed from 2,300 kcal/cap/day to 2,400 kcal/cap/day during the last 50 years, while food surplus grew from 310 kcal/cap/day to 510 kcal/cap/day. Similarly, GHG emissions related to the food surplus increased from 130 Mt CO2eq/yr to 530 Mt CO2eq/yr, an increase of more than 300%. Moreover, the global food surplus may increase up to 850 kcal/cap/day, while the total food requirement will increase only by 2%-20% by 2050. Consequently, GHG emissions associated with the food waste may also increase tremendously to 1.9-2.5 Gt CO2eq/yr. PMID:27054575

    There are many small villages where environmental contamination is substantial due to historical industrial activities. The aim of the present study was to investigate if long-term or current consumption of local foods, as reported in food frequency questionnaires, co-vary with measured concentrations of polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), lead (Pb), cadmium (Cd) and mercury (Hg) in blood, urine and hair from a population living in a historically contaminated village. Blood, urine and hair were provided by men (n=38) and women (n=57), who had participated in a previous case-control study in the contaminated area, and were analyzed for PCB, OCPs, Pb, Cd and Hg. A detailed food frequency questionnaire, used in the previous epidemiological study, was repeated, and up-dated information of life-style, exposure factors and other covariates was collected. Associations between reported consumption of local foods and exposure biomarkers were explored in relation to age, gender, life-style factors and other covariates. A large part of the population in the area reported consumption of local food, and thus, was potentially exposed to the contaminants. Despite the limited number of participants and other weaknesses described, it was possible to link reported consumption of different foods to biomarker concentrations. Reported consumption of local vegetables, forest berries and mushrooms co-varied with urinary Cd, indicating an influence from the contaminated area on the Cd exposure. We found no associations between PCB plasma concentrations with reported consumption of local fish, but with consumption of herring (non-local sea fish) which is typically high in PCB. Pesticide (HCB, p,p'-DDE, trans-nonachlor) exposure was mainly associated with agricultural work and having a private well the first five years of life, but we found no associations between pesticide concentrations in plasma and consumption of local vegetables or fish. Exposure to Hg was associated with consumption of fish, both local and non-local, and Pb exposure was associated with the consumption of game. Overall, the contaminant concentrations measured in blood, urine and hair varied substantially among study participants, but on average, the concentrations were similar to concentrations measured in other groups of the general Swedish population in the same age range. Larger studies are needed to evaluate health risks (and causality) associated with historical environmental contamination. PMID:25529270

    Due to their lipophilic properties, dioxins (PCDD/PCDFs) and other organohalogen compounds bioaccumulate in the food chain, with diet accounting for over 90% of non-occupational exposures. To date, few epidemiologic studies have examined the relationship between dioxins and breast cancer in human populations. Most have examined risks in occupational cohorts or in populations exposed to dioxins from the Seveso accident6-8. Results from these studies have been conflicting and have largely been limited by a lack of individual-level measures of exposure, small numbers of cases, and inability to account for established breast cancer risk factors. Very little is known about the potential health effects of low-level environmental dioxin contamination. We present data on PCDD/PCDFs, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in adipose tissues of women participating in a breast cancer case-control study centered in the San Francisco Bay Area. In addition, we examine distributions of these chemicals in breast and abdominal adipose of women undergoing mastectomies with concurrent breast reconstruction. If concentrations were equivalent, use of abdominal adipose would greatly enhance the pool for controls for future epidemiological studies.

  11. Incidence of liver tumors in beagles with body burdens of 239Pu or 241Am

    International Nuclear Information System (INIS)

    Tetravalent 239Pu or trivalent 241Am in a citrate buffer, given via a single intravenous injection to beagles, induced very pronounced liver changes, usually at relatively long postinjection times. The lesions consisted of cell injury or cell necrosis which was followed by nodular hyperplasia and a significant incidence of primary liver tumors. The most frequent neoplasm was the bile duct adenoma, followed by the bile duct carcinoma. A lesser number of sarcomas were also induced, especially fibrosarcomas. The number of hepatic cell tumors was low. An abnormally high incidence of both hyperplastic nodules and primary liver tumors occurred at long postinjection times and at average doses extending down to ∼10 rads. The various nodular lesions and liver tumors frequently occurred as incidental findings in dogs dying from other causes, especially bone cancer. In comparison to bone neoplasia, the liver was a much less important target organ in the high-dose level groups, but in some of the low-dose groups, especially in the 241Am groups, the risk of radiation-induced liver cancer was approximately equal to or exceeded the risk of skeletal tumors. However, in any projection of the risks observed in this animal model to man, one should be mindful that the beagle skeleton is approximately 25 times more sensitive to radiation-induced bone neoplasia than is the human skeleton (Mays et al., 1976) and that the radiosensitivity difference for the beagle and human liver is unknown. 41 refs., 8 figs., 5 tabs

    In spring 1999, Belgium faced a severe food contamination when about 50 kg of PCBs containing 1 g of dioxins were introduced in the food chain. The possible public health impact of this food chain contamination was subject of a debate between different scientists. According to Vrijens et al. and Bernard et al. there was no significant public health impact, whereas van Larebeke et al. presumed the opposite claiming a significant increase of cancer incidence. These risk assessments were based on measurements of dioxins/PCBs in contaminated foods and nutritional habits observed in a selected group of adolescents (14-18 years old) using simulation techniques or on the estimation of the incremental cancer risk associated with the incremental levels of exposure to dioxins/PCBs during the incident.

    Objectives To describe the burden experienced by family caregivers of older adults with depression and to examine the positive effects on caregivers of treating late-life depression. Design Two-phase treatment study for major depressive disorder (MDD) that included 6 weeks of open treatment with antidepressant medication for all older patients followed by 16 weeks of randomized treatment for patients who were partial responders, comparing a combination of medication and interpersonal psychotherapy with medication alone. Setting Primary care and university late-life mental health research clinic. Participants Adults aged 60 and older participating in a randomized trial for treatment of MDD who enrolled in a family caregiver study and their caregiver (N = 244 dyads). Measurements Improvement in patient symptoms during open treatment (lower scores on the Hamilton Rating Scale for Depression (HRSD)) and remission of depression during randomized treatment (3 consecutive weekly HRSD scores of ≤7) were examined as predictors of lower general caregiver burden and burden specific to patient depression. Results Caregivers reported a moderate to high level of general caregiver burden on average. Change in patient depression during open treatment was associated with significantly decreased depression-specific burden (β = −0.22, P =.001) and a trend toward lower general burden (β = − 0.08, P =.08). Caregivers of patients who remitted showed significantly decreased depression-specific burden (F (1,76) = 4.27, P =.04). Conclusion Treatment of late-life depression has benefits that extend to the family members on whom patients depend. Caregiver education and support may strengthen these effects. PMID:19943833

    Full Text Available BACKGROUND: Dengue poses a substantial economic and disease burden in Southeast Asia (SEA. Quantifying this burden is critical to set policy priorities and disease-control strategies. METHODS AND FINDINGS: We estimated the economic and disease burden of dengue in 12 countries in SEA: Bhutan, Brunei, Cambodia, East-Timor, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Viet Nam. We obtained reported cases from multiple sources--surveillance data, World Health Organization (WHO, and published studies--and adjusted for underreporting using expansion factors from previous literature. We obtained unit costs per episode through a systematic literature review, and completed missing data using linear regressions. We excluded costs such as prevention and vector control, and long-term sequelae of dengue. Over the decade of 2001-2010, we obtained an annual average of 2.9 million (m dengue episodes and 5,906 deaths. The annual economic burden (with 95% certainty levels was US$950m (US$610m-US$1,384m or about US$1.65 (US$1.06-US$2.41 per capita. The annual number of disability-adjusted life years (DALYs, based on the original 1994 definition, was 214,000 (120,000-299,000, which is equivalent to 372 (210-520 DALYs per million inhabitants. CONCLUSION: Dengue poses a substantial economic and disease burden in SEA with a DALY burden per million inhabitants in the region. This burden is higher than that of 17 other conditions, including Japanese encephalitis, upper respiratory infections, and hepatitis B.

    Full Text Available Despite the increasing availability of typhoid vaccine in many regions, global estimates of mortality attributable to enteric fever appear stable. While both Salmonella enterica serovar Typhi (S. Typhi and serovar Paratyphi (S. Paratyphi cause enteric fever, limited data exist estimating the burden of S. Paratyphi, particularly in Asia and Africa. We performed a systematic review of both English and Chinese-language databases to estimate the regional burden of paratyphoid within Africa and Asia. Distinct from previous reviews of the topic, we have presented two separate measures of burden; both incidence and proportion of enteric fever attributable to paratyphoid. Included articles reported laboratory-confirmed Salmonella serovar classification, provided clear methods on sampling strategy, defined the age range of participants, and specified the time period of the study. A total of 64 full-text articles satisfied inclusion criteria and were included in the qualitative synthesis. Paratyphoid A was commonly identified as a cause of enteric fever throughout Asia. The highest incidence estimates in Asia came from China; four studies estimated incidence rates of over 150 cases/100,000 person-years. Paratyphoid A burden estimates from Africa were extremely limited and with the exception of Nigeria, few population or hospital-based studies from Africa reported significant Paratyphoid A burden. While significant gaps exist in the existing population-level estimates of paratyphoid burden in Asia and Africa, available data suggest that paratyphoid A is a significant cause of enteric fever in Asia. The high variability in documented incidence and proportion estimates of paratyphoid suggest considerable geospatial variability in the burden of paratyphoid fever. Additional efforts to monitor enteric fever at the population level will be necessary in order to accurately quantify the public health threat posed by S. Paratyphi A, and to improve the prevention

    Full Text Available Rabies is a notoriously underreported and neglected disease of low-income countries. This study aims to estimate the public health and economic burden of rabies circulating in domestic dog populations, globally and on a country-by-country basis, allowing an objective assessment of how much this preventable disease costs endemic countries.We established relationships between rabies mortality and rabies prevention and control measures, which we incorporated into a model framework. We used data derived from extensive literature searches and questionnaires on disease incidence, control interventions and preventative measures within this framework to estimate the disease burden. The burden of rabies impacts on public health sector budgets, local communities and livestock economies, with the highest risk of rabies in the poorest regions of the world. This study estimates that globally canine rabies causes approximately 59,000 (95% Confidence Intervals: 25-159,000 human deaths, over 3.7 million (95% CIs: 1.6-10.4 million disability-adjusted life years (DALYs and 8.6 billion USD (95% CIs: 2.9-21.5 billion economic losses annually. The largest component of the economic burden is due to premature death (55%, followed by direct costs of post-exposure prophylaxis (PEP, 20% and lost income whilst seeking PEP (15.5%, with only limited costs to the veterinary sector due to dog vaccination (1.5%, and additional costs to communities from livestock losses (6%.This study demonstrates that investment in dog vaccination, the single most effective way of reducing the disease burden, has been inadequate and that the availability and affordability of PEP needs improving. Collaborative investments by medical and veterinary sectors could dramatically reduce the current large, and unnecessary, burden of rabies on affected communities. Improved surveillance is needed to reduce uncertainty in burden estimates and to monitor the impacts of control efforts.

    Objective To investigate the role of the burden of abnormal hematopoietic clone in the development of myelodys plastic syndromes (MDS).Methods The ratio of the bone marrow cells with abnormal chromosomes to the total counted bone marrow cells was regarded as the index of MDS clone burden. The disease severity related parameters including white blood cell count, hemoglobin, platelet count, lactate dehydrogenase level, bone marrow blast, myeloid differentiation index, micromegakaryocyte, transfusion, interleukin-2, tumor necrosis factor ( TNF), CD4 + and CD8 + T cells of MDS patients were assayed, and the correlations between those parameters and MDS clone burden were also analyzed.Results The clone burden of MDS patients was 67.4% ± 36. 2%. MDS clone burden positively correlated with bone marrow blasts (r=0.483, P<0.05), negatively with hemoglobin level (r=-0.445, P<0.05). The number of blasts, hemoglobin, and erythrocytes in high clone burden (>50%) and low clone burden (≤50%) groups were 7.78%±5.51% and 3.45%±3.34%, 56.06±14. 28 g/L and 76.40±24.44 g/L, (1.82±0.48)×1012/L and (2. 32±0.66)×1012/L, respectively (all P <0.05). CD4 + T lymphocytes of MDS patients and normal controls were (0. 274±0.719)×109/L and (0.455±0.206)×109/L, respectively (P<0.05). CD8 ± T lymphocytes of MDS patients and normal controls were (0.240±0.150)×109/L and (0.305 ±0.145)×109/L, respectively. The serum level of interleukin-2 of MDS patients (6.29±3.58 ng/mL) was significantly higher than normal control (3.11±1.40ng/mL, P<0.05). The serum level of TNF of MDS patients and normal control group were 2.42±1.79 ng/mL and 1.68 ±0.69 ng/mL, respectively. The ratio of CD4 to CD8 was higher in high clone burden MDS patients (1.90 ±0.52) than that in low clone burden patients (0.97±0.44, P<0.05).Conclusion The quantitive clonal karyotype abnormalities and deficient T cell immunity are important parameters for evaluating MDS severity and predicting its

Despite its low prevalence, its health, social, and economic burden has been tremendous, not only for patients but also for families, caregivers, and the wider society. The magnitude of disease burden investigated in an economic burden study is an important source to policymakers in decision making. This study aims to systematically identify studies focusing on the economic burden of schizophrenia, describe the methods and data sources used, and summarize the findings of economic burden of schizophrenia. Methods: A systematic review was performed for economic burden studies in schizophrenia using four electronic databases (Medline, EMBASE, PsycINFO, and EconLit from inception to August 31, 2014. Results: A total of 56 articles were included in this review. More than 80% of the studies were conducted in high-income countries. Most studies had undertaken a retrospective- and prevalence-based study design. The bottom-up approach was commonly employed to determine cost, while human capital method was used for indirect cost estimation. Database and literature were the most commonly used data sources in cost estimation in high-income countries, while chart review and interview were the main data sources in low and middle-income countries. Annual costs for the schizophrenia population in the country ranged from US$94

    The risks and benefits of using mercury (Hg) in dental amalgam have long been debated. This study was designed to estimate Hg body burden and its association with dental amalgam fillings in 182 children (ages: 5-15 years) living in Taif City. Hg was measured in urine (UHg), hair (HHg) and toenails (NHg) by the Atomic Absorption Spectrophotometer with Vapor Generator Accessory system. Urinary Hg levels were calculated as both micrograms per gram creatinine (μg/g creatinine) and micrograms per liter (μg/L). We found that children with amalgam fillings (N=106) had significantly higher UHg-C levels than children without (N=76), with means of 3.763 μg/g creatinine versus 3.457 μg/g creatinine, respectively (P=0.019). The results were similar for UHg (P=0.01). A similar pattern was also seen for HHg, with means of 0.614 μg/g (N=97) for children with amalgam versus 0.242 μg/g (N=74) for those without amalgam fillings (P=0). Although the mean NHg was higher in children without amalgam (0.222 μg/g, N=61) versus those with (0.163 μg/g, N=101), the relationship was not significant (P=0.069). After adjusting for many confounders, the multiple logistic regression model revealed that the levels of UHg-C and HHg were 2.047 and 5.396 times higher, respectively, in children with dental amalgam compared to those without (Pdental amalgam fillings (P=0.003). Despite the controversy surrounding the health impact of dental amalgam, this study showed some evidence that amalgam-associated Hg exposure might be related with symptoms of oral health, such as aphthous ulcer, white patches, and a burning-mouth sensation. Further studies are needed to reproduce these findings. The present study showed that significant numbers of children with or without amalgam had Hg levels exceeding the acceptable reference limits. The detrimental neurobehavioral and/or nephrotoxic effects of such an increased Hg on children should be a cause of concern, and further investigation is warranted. Our

    Full Text Available Abstract Attention-deficit hyperactivity disorder (ADHD is a common disorder that is associated with broad functional impairment among both children and adults. The purpose of this paper is to review and summarize available literature on the economic costs of ADHD, as well as potential economic benefits of treating this condition. A literature search was performed using MEDLINE to identify all published articles on the economic implications of ADHD, and authors were contacted to locate conference abstracts and articles in press that were not yet indexed. In total, 22 relevant items were located including published original studies, economic review articles, conference presentations, and reports available on the Internet. All costs were updated and presented in terms of year 2004 US dollars. A growing body of literature, primarily published in the United States, has demonstrated that ADHD places a substantial economic burden on patients, families, and third-party payers. Results of the medical cost studies consistently indicated that children with ADHD had higher annual medical costs than either matched controls (difference ranged from $503 to $1,343 or non-matched controls (difference ranged from $207 to $1,560 without ADHD. Two studies of adult samples found similar results, with significantly higher annual medical costs among adults with ADHD (ranging from $4,929 to $5,651 than among matched controls (ranging from $1,473 to $2,771. A limited number of studies have examined other economic implications of ADHD including costs to families; costs of criminality among individuals with ADHD; costs related to common psychiatric and medical comorbidities of ADHD; indirect costs associated with work loss among adults with ADHD; and costs of accidents among individuals with ADHD. Treatment cost-effectiveness studies have primarily focused on methylphenidate, which is a cost-effective treatment option with cost-effectiveness ratios ranging from $15

    Full Text Available The results of an analytical assessment of the developed frame of reference on concepts of tax planning, tax burden, tax burden of the enterprise are presented in article. Tax planning is the most important part of financial planning of the organization. A basis of this process is possibility of each taxpayer to use legislatively resolved means, receptions and ways directed on minimization of tax payments. Minimization of taxes is directed not only on absolute decrease in volumes of tax payments, but also on purposeful transfer of business to more favorable conditions of managing. Tax planning is connected with recognition of the right of each taxpayer to apply all legislatively resolved means, receptions and ways to decrease in tax payments. The analysis of a condition of tax burden of an economic entity of real sector of economy is carried out. It is noted, that by means of various techniques of its assessment it is possible to receive contradictory data on dynamics of change of level of tax burden. As one of factors of increasing the efficiency of business activity is optimization of tax payments and implementation of tax planning acts. Importance of realization of tax planning and optimization of tax payments is defined by desire of taxpayers to lower tax burden and explainable aspiration of the state to prevent it

    A systematic literature review was performed regarding the burden on mental health caregivers. The studies were selected from the Virtual Health Library - Biblioteca Virtual de Saúde (BVS), using the keyword caregiver burden. The main criteria for this study were: full-text articles published between 2000 and 2010, in Portuguese, English or Spanish; indexed on the BVS databases; which investigated the burden of mental health caregivers, and had caregivers as the main subject. The analysis was performed considering the following: title, year of publication, objectives, methodological approach, instruments and main results. The analysis of 114 full-text articles showed the predominant objectives were the burden on informal caregivers and the validation of psychometric scales, particularly the Zarit Scale. Some studies showed an association between high levels of burden, feelings of guilt and depressive symptoms. On the other hand, psycho-educational interventions were indicated as having a positive impact. This theme has a growing scientific interest and there is a need for deeper studies addressing formal caregivers.

    The high-tech art of digital signal processing (DSP) was pioneered at NASA's Jet Propulsion Laboratory (JPL) in the mid-1960s for use in the Apollo Lunar Landing Program. Designed to computer enhance pictures of the Moon, this technology became the basis for the Landsat Earth resources satellites and subsequently has been incorporated into a broad range of Earthbound medical and diagnostic tools. DSP is employed in advanced body imaging techniques including Computer-Aided Tomography, also known as CT and CATScan, and Magnetic Resonance Imaging (MRI). CT images are collected by irradiating a thin slice of the body with a fan-shaped x-ray beam from a number of directions around the body's perimeter. A tomographic (slice-like) picture is reconstructed from these multiple views by a computer. MRI employs a magnetic field and radio waves, rather than x-rays, to create images.

    Engineering cell metabolism for bioproduction not only consumes building blocks and energy molecules (e.g., ATP) but also triggers energetic inefficiency inside the cell. The metabolic burdens on microbial workhorses lead to undesirable physiological changes, placing hidden constraints on host productivity. We discuss cell physiological responses to metabolic burdens, as well as strategies to identify and resolve the carbon and energy burden problems, including metabolic balancing, enhancing respiration, dynamic regulatory systems, chromosomal engineering, decoupling cell growth with production phases, and co-utilization of nutrient resources. To design robust strains with high chances of success in industrial settings, novel genome-scale models (GSMs), (13)C-metabolic flux analysis (MFA), and machine-learning approaches are needed for weighting, standardizing, and predicting metabolic costs.

    This study examined hope and family burden among Latino families of individuals with schizophrenia. The sample consisted of 54 family members, one family member per outpatient adult recruited from public mental health programs in a diverse urban community. Hierarchical linear regression analyses were used to test the hypothesis that the family member’s increased hope for the patient’s future would be associated with decreased family burden beyond effects explained by the patient’s length of illness and severity of symptoms. Results supported the study hypothesis. Family hope for the patient’s future was associated with four of five types of family burden. Findings point to the prominent role of hope as a source of resilience for Latino families dealing with severe mental illness of a loved one. PMID:24329411

    The burden on health-related issues due to unplanned urban policies is higher despite the present knowledge of interventions and availability of current technologies. This burden could increase substantially, given the rapid growth in urban populations and the application of partial or misguided solutions to urban transport problems. Part of the reason is the failure to consider holistically the health, social and environment consequences and the related costs of individual travel choices and government policies in the field of traffic and mobility. Urban transport-related issues and its impact on health, environment, costs and benefits are discussed in this paper.

    The Explorer XXXIII Spacecraft (Anchored Interplanetary Monitoring Platform, or AIMP) was decontaminated to prevent gross contamination of the moon with terrestrial microorganisms. Assay of the total spacecraft surface before and after decontamination showed that the decontamination procedure reduced the viable microbiological burden from 1.40 x 10(6) to 3.60 x 10(4). However, assembly of parts which were not decontaminated for engineering reasons or were not assembled under cleanroom conditions increased the viable microbial burden at the time of launch to 2.62 x 10(5).

    Full Text Available Dengue imposes a substantial economic and disease burden in most tropical and subtropical countries. Dengue incidence and severity have dramatically increased in Mexico during the past decades. Having objective and comparable estimates of the economic burden of dengue is essential to inform health policy, increase disease awareness, and assess the impact of dengue prevention and control technologies.We estimated the annual economic and disease burden of dengue in Mexico for the years 2010-2011. We merged multiple data sources, including a prospective cohort study; patient interviews and macro-costing from major hospitals; surveillance, budget, and health data from the Ministry of Health; WHO cost estimates; and available literature. We conducted a probabilistic sensitivity analysis using Monte Carlo simulations to derive 95% certainty levels (CL for our estimates. Results suggest that Mexico had about 139,000 (95%CL: 128,000-253,000 symptomatic and 119 (95%CL: 75-171 fatal dengue episodes annually on average (2010-2011, compared to an average of 30,941 symptomatic and 59 fatal dengue episodes reported. The annual cost, including surveillance and vector control, was US$170 (95%CL: 151-292 million, or $1.56 (95%CL: 1.38-2.68 per capita, comparable to other countries in the region. Of this, $87 (95%CL: 87-209 million or $0.80 per capita (95%CL: 0.62-1.12 corresponds to illness. Annual disease burden averaged 65 (95%CL: 36-99 disability-adjusted life years (DALYs per million population. Inclusion of long-term sequelae, co-morbidities, impact on tourism, and health system disruption during outbreaks would further increase estimated economic and disease burden.With this study, Mexico joins Panama, Puerto Rico, Nicaragua, and Thailand as the only countries or areas worldwide with comprehensive (illness and preventive empirical estimates of dengue burden. Burden varies annually; during an outbreak, dengue burden may be significantly higher than that of

    Indonesia is facing household-level double burden malnutrition. This study aimed at examining (1) household-level double burden for the mother-child and father-child pairs; (2) risk of adiposity of double burden households; and (3) associated dietary factors. Subjects were 5th and 6th grade elementary school children (n = 242), their mothers (n = 242), and their fathers (n = 225) in five communities (1 = urban, 4 = rural) in the Bandung District. Questionnaires on socioeconomic factors, blood hemoglobin measurements, and anthropometric measurements were administered. For adults, body fat percentage (BF%) was estimated by bioelectrical impedance (BF%-BI) and by converting skinfold thickness (ST) data using Durnin and Womersley's (1974) formula (BF%-ST). Food frequency questionnaires were also completed. Double burden was defined as coexistence of maternal or paternal overweight (Body mass index (BMI) ≥ 23) and child stunting (height-for-age z-score 35%, and 60.6% had waists >80 cm. The major dietary patterns identified were "Modern" and "High-animal products". After controlling for confounding factors, children in the highest quartile of the "High-animal products" dietary pattern had a lower risk of maternal-child double burden (Adjusted OR: 0.46, 95% CI: 0.21-1.04) than those in the lowest quartile. Given that the "High-animal products" dietary pattern was associated with the decreased risk of maternal-child double burden through a strong negative correlation with child stunting, improving child stunting through adequate intake of animal products is critical to solve the problem of maternal-child double burden in Indonesia.

    This article discusses nine criteria for evaluation of potential Burden Sharing Rules (BSRs) in climate policy agreements. Three of the criteria reflect fairness principles while six of them are operational requirements. These criteria are useful for identifying potential BSRs that could be promising in future climate policy negotiations. The two sector approaches, Multi-sector Convergence Approach and Triptych, received the highest score according to the criteria presented in this article. The Multi-sector Convergence Approach was developed in the joint ECN (Netherlands Energy Research Foundation) and CICERO (Center for International Climate and Environmental Research - Oslo) project on burden sharing in climate policy agreements. This is a sector-oriented approach that comprises convergence of per capita emissions to the same level for all countries, and has a global coverage. The Triptych approach has been employed by the European Union for their internal differentiation of national abatement targets. Sector approaches have some specific advantages in linking burden sharing to the economic structure of countries. This indicates that the Multi-sector Convergence Approach could play a useful role in climate policy negotiations among a larger group of countries, and could encourage developing countries to take on greenhouse gas abatement targets.

    Older caregivers have major caregiving responsibilities in countries severely affected by the HIV epidemic, but little is known about their own health and well-being. We conducted this study to assess the association of caregiving responsibilities and self-perceived burden with caregivers' health, HIV status, background characteristics and care-receiving among older people in South Western Uganda. Men and women aged 50 years and older were recruited from existing cohort studies and clinic registers and interviewed at home. Health was measured through a composite score of health in eight domains, anthropometry and handgrip strength. Summary measures of caregiving responsibilities and self-reported burden were used to analyse the main associations. There were 510 participants, including 198 living with HIV. Four fifths of women and 66% of men were caregivers. Older respondents with no care responsibility had poorer scores on all health indicators (self-reported health score, body mass index and grip strength). Having a caregiving responsibility was not associated with poorer health status or quality of life. Notably, HIV-infected people, whether on antiretroviral treatment (ART) or not, had similar caregiving responsibilities and health status as others. The self-reported burden associated with caregiving was significantly associated with a poorer health score. One third of female caregivers were the single adult in the household with larger caregiving responsibilities. Many of these women are in the poorest wealth quartile of the households in the study and are therefore more likely to need assistance. Physical and financial supports were received by 70% and 63%, respectively. Those with larger caregiving responsibilities more frequently received support. Caregiving responsibilities were associated with better health status, greater satisfaction and quality of life. Older HIV-infected people, whether on ART or not, had similar caregiving responsibilities and self

    Full Text Available Introduction. Lifestyle-related risk factors: smoking, obesity, sedentariness and excess alcohol intake are among the most important known causes of cancer and cardiovascular disease. The aim of this study is to examine the relationship between these lifestyle-related risk factors for cancer/cardiovascular disease and working conditions among surgeons/anesthesiologists and other physicians. Material and Methods. The study was carried out among physicians aged 35 to 60, without diagnosed coronary heart disease or other structural heart disease, who were employed at the Novi Sad University Hospital. The participation rate was high (> 90%. The physicians completed the Occupational Stress Index. Low lifestyle-related cancer/cardiovascular risk was defined as: not a current smoker, body mass index < 28, regular recreational physical activity and not consuming alcohol every day. Analysis of covariance was performed. Results. Of 191 physicians included in this study only 23 (12.0% had a low lifestyle- related cancer/cardiovascular risk. Surgeons/anesthesiologists faced a heavier total work stressor burden than physicians in other profiles (87.7±8.8 versus 74.1±10.5, p=0.000. Among the 56 surgeons/anesthesiologists, lower nightshift work scores were associated with low lifestyle-related cancer/cardiovascular risk (F=4.19, p=0.046. A lower overall work stressor burden was associated with low risk among the other 135 physicians (F=4.06, p=0.046. Conclusion. Specific workplace intervention strategies are urgently needed. Among the surgeons/anesthesiologists these should include reduction in the frequency of night call and improvement of the overall conditions of nightshift work. Among other physicians, the total occupational burden needs to be diminished.

  5. Sacralising Bodies

    DEFF Research Database (Denmark)

    Kaur, Ravinder

    2010-01-01

    In post-revolution Iran, the sacred notion of martyrdom has been transformed into a routine act of government – a moral sign of order and state sovereignty. Moving beyond the debates of the secularisation of the sacred and the making sacred of the secular, this article argues that the moment...... of sacralisation is realised through co-production within a social setting when the object of sacralisation is recognised as such by others. In contemporary Iran, however, the moment of sacralising bodies by the state is also the moment of its own subversion as the political-theological field of martyrdom......-sacrifice became central to the mass mobilisation against the monarchy. Once the revolutionary government came into existence, this sacred tradition was regulated to create ‘martyrs’ as a fixed category, in order to consolidate the legacy of the revolution. In this political theatre, the dead body is a site...

    We related reported physical symptoms, cognitive appraisals (e.g., negative style of thinking), and coping strategies (e.g., denial/disengagement strategies) with illness burden across several functional domains separately in subsets of chronic fatigue syndrome (CFS) patients with (n = 26) and without (n = 39) concurrently diagnosed major depressive disorder (MDD). In regard to cognitive appraisal measures, automatic thoughts and dysfunctional attitudes were strongly associated with a higher illness burden, as indicated in sickness impact profile (SIP) scores. Active-involvement coping strategies measured on COPE scales (active coping, planning, and positive reinterpretation and growth) were not associated with SIP scores, while other coping strategies (mental disengagement, behavioral disengagement, and denial) were positively correlated with psychosocial and physical SIP scales, especially those pertaining to interpersonal life-style arenas. After we accounted for the number of different CFS-specific physical complaints reported and DSM-III-R depression diagnosis status, cognitive appraisals and coping strategies predicted a substantial proportion of the variance in the severity of illness burden. For the most part, the magnitude of these relationships between our predictor model variables and illness burden severity was similar in the MDD and non-MDD subgroups. PMID:8148457

    Directory of Open Access Journals (Sweden)

    Claudia Stein

    Full Text Available The Global Burden of Disease (GBD concept has been used by the World Health Organization (WHO for its reporting on health information for nearly 10 years. The GBD approach results in a single summary measure of morbidity, disability, and mortality, the so-called disability-adjusted life year (DALY. To ensure transparency and objectivity in the derivation of health information, WHO has been urged to use reference groups of external experts to estimate burden of disease. Under the leadership and coordination of WHO, expert groups have been appraising and abstracting burden of disease information. Examples include the Child Health Epidemiology Reference Group (CHERG, the Malaria Monitoring and Evaluation Reference Group (MERG, and the recently established Foodborne Disease Burden Epidemiology Reference Group (FERG. The structure and functioning of and lessons learnt by these groups are described in this paper. External WHO expert groups have provided independent scientific health information while operating under considerable differences in structure and functioning. Although it is not appropriate to devise a single "best practice" model, the common thread described by all groups is the necessity of WHO's leadership and coordination to ensure the provision and dissemination of health information that is to be globally accepted and valued.

    Full Text Available Objectives. The aim of this study is to estimate the economic burden associated with the management of periodontitis in Malaysia from the societal perspective. Methods. We estimated the economic burden of periodontitis by combining the disease prevalence with its treatment costs. We estimated treatment costs (with 2012 value of Malaysian Ringgit using the cost-of-illness approach and included both direct and indirect costs. We used the National Oral Health Survey for Adults (2010 data to estimate the prevalence of periodontitis and 2010 national census data to estimate the adult population at risk for periodontitis. Results. The economic burden of managing all cases of periodontitis at the national level from the societal perspective was approximately MYR 32.5 billion, accounting for 3.83% of the 2012 Gross Domestic Product of the country. It would cost the nation MYR 18.3 billion to treat patients with moderate periodontitis and MYR 13.7 billion to treat patients with severe periodontitis. Conclusion. The economic burden of periodontitis in Malaysia is substantial and comparable with that of other chronic diseases in the country. This is attributable to its high prevalence and high cost of treatment. Judicious application of promotive, preventive, and curative approaches to periodontitis management is decidedly warranted.

    Full Text Available Zoonotic disease (ZD pose a serious threat to human health in low-income countries. In these countries the human burden of disease is often underestimated due to insufficient monitoring because of insufficient funding. Quantification of the impact of zoonoses helps in prioritizing healthcare needs. Kyrgyzstan is a poor, mountainous country with 48% of the population employed in agriculture and one third of the population living below the poverty line.We have assessed the burden of zoonoses in Kyrgyzstan by conducting a systematic review. We have used the collected data to estimate the burden of ZDs and addressed the underestimation in officially reported disease incidence. The estimated incidences of the ZDs were used to calculate incidence-based Disability Adjusted Life Years (DALYs. This standardized health gap measure enhances comparability between injuries and diseases. The combined burden for alveolar echinococcosis, cystic echinococcosis, brucellosis, campylobacteriosis, congenital toxoplasmosis, non-typhoidal salmonellosis and rabies in Kyrgyzstan in 2013 was 35,209 DALYs [95% Uncertainty interval (UI:13,413-83,777]; 576 deaths [95% UI: 279-1,168] were attributed to these infections. We estimate a combined median incidence of ZDs of 141,583 cases [95% UI: 33,912-250,924] in 2013. The highest burden was caused by non-typhoidal Salmonella and Echinococcus multilocularis, respectively 14,792 DALYs [95% UI: 3,966-41,532] and 11,915 DALYs [95% UI: 4,705-27,114] per year.The health impact of zoonoses in Kyrgyzstan is substantial, comparable to that of HIV. Community-based surveillance studies and hospital-based registration of all occurrences of zoonoses would increase the accuracy of the estimates.

    Although allogeneic hematopoietic cell transplantation (HCT) is an expensive treatment for hematological disorders, little is known about the financial consequences for the patients who undergo this procedure. We analyzed factors associated with its financial burden and its impact on health behaviors of allogeneic HCT recipients. A questionnaire was retrospectively mailed to 482 patients who underwent allogeneic HCT from January 2006 to June 2012 at the Mayo Clinic, to collect information regarding current financial concerns, household income, employment, insurance, out-of-pocket expenses, and health and functional status. A multivariable logistic regression analysis identified factors associated with financial burden and treatment nonadherence. Of the 268 respondents (56% response rate), 73% reported that their sickness had hurt them financially. All patients for whom the insurance information was available (missing, n = 13) were insured. Forty-seven percent of respondents experienced financial burden, such as household income decreased by >50%, selling/mortgaging home, or withdrawing money from retirement accounts. Three percent declared bankruptcy. Younger age and poor current mental and physical functioning increased the likelihood of financial burden. Thirty-five percent of patients reported deleterious health behaviors because of financial constraints. These patients were likely to be younger, have lower education, and with a longer time since HCT. Being employed decreased the likelihood of experiencing financial burden and treatment nonadherence due to concern about costs. A significant proportion of allogeneic HCT survivors experience financial hardship despite insurance coverage. Future research should investigate potential interventions to help at-risk patients and prevent adverse financial outcomes after this life-saving procedure.

    Vitiligo has a major impact on health-related quality of life. Although a few vitiligo-specific quality of life instruments exist, there is no specific vitiligo burden tool. We developed and validated a specific vitiligo burden tool according to skin phototype. In total, 301 patients completed 35 items of the Vitiligo Impact Patient scale, of whom 235 were of skin phototype I to III and 66 of phototype IV to VI. The dimensionality of the items was evaluated using factor analyses, with results suggesting three factors in fair- and dark-skinned patients ("Psychological effects on daily life," "Relationships and Sexuality," and "Economic Constraints, Care & Management of Disease"). Unidimensionality was confirmed by higher order factor analysis. Cronbach's α were high-and intradimensional coherences all demonstrated good reliability (α > 0.8). The final instrument consists of 29 items (19 items common to all patients, 3 specific to fair skin, and 7 to dark skin). The test-retest reliability demonstrated very good reproducibility. The intraclass correlation of each dimension was greater than 0.90 for each population. External validity was confirmed by the correlation coefficients and Bland and Altman plots of the Vitiligo Impact Patient scale-Fair Skin and Vitiligo Impact Patient scale-Dark Skin versus the Short-Form-12, PVC Metra, Body Image States Scale, and Daily Life Quality Index assessment tools.

    Full Text Available Abstract Background Adhesions are fibrous bands of scar tissue, often a result of surgery, that form between internal organs and tissues, joining them together abnormally. Postoperative adhesions frequently occur following abdominal surgery, and are associated with a large economic burden. This study examines the inpatient burden of adhesiolysis in the United States (i.e., number and rate of events, cost, length of stay [LOS]. Methods Hospital discharge data for patients with primary and secondary adhesiolysis were analyzed using the 2005 Healthcare Cost and Utilization Project's Nationwide Inpatient Sample. Procedures were aggregated by body system. Results We identified 351,777 adhesiolysis-related hospitalizations: 23.2% for primary and 76.8% for secondary adhesiolysis. The average LOS was 7.8 days for primary adhesiolysis. We found that 967,332 days of care were attributed to adhesiolysis-related procedures, with inpatient expenditures totaling $2.3 billion ($1.4 billion for primary adhesiolysis; $926 million for secondary adhesiolysis. Hospitalizations for adhesiolysis increased steadily by age and were higher for women. Of secondary adhesiolysis procedures, 46.3% involved the female reproductive tract, resulting in 57,005 additional days of care and $220 million in attributable costs. Conclusions Adhesiolysis remain an important surgical problem in the United States. Hospitalization for this condition leads to high direct surgical costs, which should be of interest to providers and payers.

The importance of effective antipsychotic therapy in reducing the burden of schizophrenia is also examined.Methods: Published research on the burden, disability, management, and economic costs of schizophrenia in the People's Republic of China was examined in the context of the larger body of global research. Research written in English or Chinese and published before June 2012 was identified using PubMed, CNKI, and Wanfang Med database searches. The contribution of effective antipsychotic therapy in reducing the risk for relapse and hospitalization and improving patients' functioning is described.Results: Schizophrenia imposes a substantial burden on Chinese society, with indirect costs accounting for the majority of the total cost. Functional impairment is high, leading to lost wages and work impairment. In the People's Republic of China, schizophrenia is the most common diagnosis among hospitalized psychiatric patients. Ongoing changes in the Chinese health care system may reduce some barriers to effective relapse prevention in schizophrenia and potentially reduce hospitalizations. The use of antipsychotics for acute episodes and maintenance treatment has been shown to decrease symptom severity and reduce the risk for relapse and hospitalization. However, discontinuing

    Disposable, body-worn pads are the product most commonly chosen to contain and absorb urine and faeces (Pomfret, 2000). The cost to the NHS of supplying continence pads has been estimated at 80 million pounds per annum (Euromonitor, 1999) and is a huge financial burden on local services. PMID:16052946

  10. Mercury (Hg) burden in children: The impact of dental amalgam

    International Nuclear Information System (INIS)

    The risks and benefits of using mercury (Hg) in dental amalgam have long been debated. This study was designed to estimate Hg body burden and its association with dental amalgam fillings in 182 children (ages: 5-15 years) living in Taif City. Hg was measured in urine (UHg), hair (HHg) and toenails (NHg) by the Atomic Absorption Spectrophotometer with Vapor Generator Accessory system. Urinary Hg levels were calculated as both micrograms per gram creatinine (μg/g creatinine) and micrograms per liter (μg/L). We found that children with amalgam fillings (N = 106) had significantly higher UHg-C levels than children without (N = 76), with means of 3.763 μg/g creatinine versus 3.457 μg/g creatinine, respectively (P = 0.019). The results were similar for UHg (P = 0.01). A similar pattern was also seen for HHg, with means of 0.614 μg/g (N = 97) for children with amalgam versus 0.242 μg/g (N = 74) for those without amalgam fillings (P = 0). Although the mean NHg was higher in children without amalgam (0.222 μg/g, N = 61) versus those with (0.163 μg/g, N = 101), the relationship was not significant (P = 0.069). After adjusting for many confounders, the multiple logistic regression model revealed that the levels of UHg-C and HHg were 2.047 and 5.396 times higher, respectively, in children with dental amalgam compared to those without (P < 0.01). In contrast, a significant inverse relationship was seen between NHg levels and dental amalgam fillings (P = 0.003). Despite the controversy surrounding the health impact of dental amalgam, this study showed some evidence that amalgam-associated Hg exposure might be related with symptoms of oral health, such as aphthous ulcer, white patches, and a burning-mouth sensation. Further studies are needed to reproduce these findings. The present study showed that significant numbers of children with or without amalgam had Hg levels exceeding the acceptable reference limits.

    2016-01-01

    A growing body of health determinants research recognizes that housing and health are intimately linked. This study explores the relationship between rent burden (the ratio of rent to income) and health risk behaviors among a sample of single room occupancy (SRO) building residents. Cross-sectional data were gathered from a sample of 162 residents living in privately owned, for-profit SROs in Chicago. Findings indicated that participants who had full rental subsidies and thus were designated in a no-rent-burden category were more likely to engage in risk behaviors including illicit drug use, having multiple sexual partners, and having sex without a condom, in comparison to participants with moderate or high-rent burdens. These findings suggest that interventions to increase housing stability and affordability and bolster reliable income sources (in addition to rental subsidies) may be key in reducing risk behaviors and improving health for vulnerably housed populations such as SRO residents.

    Gidwani, Suman; Nair, Ajith

    2014-09-01

    Pulmonary vascular disease (PVD) is a significant global health problem and accounts for a substantial portion of cardiovascular disease in the developing world. Although there have been considerable advances in therapeutics for pulmonary arterial hypertension, over 97% of the disease burden lies within the developing world where there is limited access to health care and pharmaceuticals. The causes of pulmonary arterial hypertension differ between industrialized and developing nations. Infectious diseases-including schistosomiasis human immunodeficiency virus, and rheumatic fever-are common causes of PVD, as are hemoglobinopathies, and untreated congenital heart disease. High altitude and exposure to household air pollutants also contribute to a significant portion of PVD cases. Although diagnosis of pulmonary arterial hypertension requires the use of imaging and invasive hemodynamics, access to equipment may be limited. PVD therapies may be prohibitively expensive and limited to a select few. Prevention is therefore important in limiting the global PVD burden. PMID:25667181

    In this paper we discuss long-term least cost CO2stabilization scenarios based on the SRES AIM A1B scenario in the contextof an international burden-sharing regime. Starting from a stabilizationtarget, regional emission caps are formulated dynamically on the basis ofpast emissions. With these regional caps, the cost-optimal supply fuelmix in the energy sector in the four SRES world regions is calculated,and lower bounds on the volume of traded carbon are estimated. Theallocation scheme provides incentives for early mitigation action. Weestimate additional regional costs incurred by the allocation scheme, andassess the sensitivity of results to changes in the concentrationceiling, discount rates, and start date for burden sharing.

    The purpose of this study is to identify characteristics that would increase the likelihood that a Korean older adult with dementia being cared for by a family caregiver is at risk of being abused. This analysis was based on a sample of 481 primary family caregivers from the data of Comprehensive Study for the Elderly Welfare Policy in Seoul (2003). Multiple regression analysis was used to examine predictors among the demographic characteristics of caregivers and care recipients, the severity of cognitive impairment, functional ability, caregiver burden, and social support for the degree of elder abuse. The degree of elder abuse was significantly associated with caregiver burden, mental impairment, dependency of daily living of care recipient, and use of formal services. PMID:16611617

    Full Text Available Background/Aims: The relationship between carotid artery plaque burden, phenotype and serum cystatin C at normal and impaired renal function is still unclear. Methods: Demographic characteristics, carotid ultrasonography and other relevant information of 1,477 patients were collected. The association of carotid artery plaque burden, plaque phenotype with serum cystatin C was evaluated by strategy analysis based on renal function. Results: Serum cystatin C (OR=2.05, 95% CI: 1.83-2.29, POR=1.60, 95%CI: 1.43-1.78, POR=1.21, 95%CI: 1.10-1.32, P Conclusion: In normal renal function, serum cystatin C may confer stability of plaques. In mildly impaired renal function, serum cystatin C is a risk predictor of plaques. In normal renal function circumstances, serum cystatin C may benefit to the stability of plaques. In mild impaired renal function circumstances, serum cystatin C are a risk predictors of plaques.

    2016-03-30

    Fish farming is increasingly dependent on plant commodities as a source of feed leading to an increased risk for pesticide residues in aquaculture diets and consequently their transfer into aquaculture food products. The European pesticide regulation requires fish metabolism and fish feeding studies where residues in fish feed exceed 0.1 mg kg(-1) of the total diet (dry weight basis) to enable the setting of appropriate maximum residue levels in fish commodities. Fish dietary burden calculation is therefore an important prerequisite to decide on further experimental testing as part of the consumer risk assessment. In this review, the different aquaculture production systems are compared with regard to their specific feeding practices and the principles of dietary burden calculation are described.

  19. Reducing the Health Burden of HPV Infection Through Vaccination

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Human papillomavirus (HPV, a sexually transmitted infection and the etiologic cause of genital warts and cervical cancer, is highly prevalent in sexually active men and women. Although cervical screening procedures have significantly reduced the disease burden associated with HPV infection, they are expensive and abnormal results cause significant emotional distress. Therefore, prevention may be an effective strategy for reducing the economic, psychosocial, and disease burden of HPV infection. Multivalent vaccines are now in clinical development. A bivalent vaccine that protects against HPV 16 and 18, and a quadrivalent vaccine which protects against HPV types 6, 11, 16, and 18, have been shown to significantly reduce the occurrence of incident and persistent HPV infections in phase 2 clinical trials; phase 3 trials are currently underway. HPV vaccines will be most effective when administered prior to initiation of sexual activity, and vaccination campaigns should aggressively target preadolescent and adolescent populations.

    Vaccine probe studies have emerged in the past 15 years as a useful way to characterise disease. By contrast, traditional studies of vaccines focus on defining the vaccine effectiveness or efficacy. The underlying basis for the vaccine probe approach is that the difference in disease burden between vaccinated and unvaccinated individuals can be ascribed to the vaccine-specific pathogen. Vaccine probe studies can increase understanding of a vaccine’s public health value. For instance, even whe...

    Full Text Available A wide range of vascular burden factors have been identified to impact vascular function and structure as indicated by carotid intima-media thickness (IMT. On the basis of their impact on IMT, vascular factors may be selected and clustered in a vascular burden index (VBI. Since many vascular factors increase the risk of Alzheimer's disease (AD, a multifactorial neurodegenerative VBI may be related to early pathological processes in AD and cognitive decline in its preclinical stages.We investigated an elderly cohort at risk for neurodegeneration (TREND study, n = 1102 for the multifactorial influence of vascular burden factors on IMT measured by ultrasound. To create a VBI for this cohort, vascular factors and their definitions (considering medical history, medication and/or blood marker data were selected based on their statistical effects on IMT in multiple regressions including age and sex. The impact of the VBI on cognitive performance was assessed using the Trail-Making Test (TMT and the CERAD neuropsychological battery.IMT was significantly predicted by age (standardized β = .26, sex (.09; males > females and the factors included in the VBI: obesity (.18, hypertension (.14, smoking (.08, diabetes (.07, and atherosclerosis (.05, whereas other cardiovascular diseases or hypercholesterolemia were not significant.

    2009-01-01

    Full Text Available Abstract Background Burden of disease is a joint measure of mortality and morbidity which makes it easier to compare health problems in which these two components enjoy different degrees of relative importance. The objective of this study is ascertaining the burden of disease due to cancer in Spain via the calculation of disability-adjusted life years (DALYs. Methods DALYs are the sum of years of life lost due to premature mortality and years lost due to disability. World Health Organization methodology and the following sources of data were used: the Mortality Register and Princeton Model Life Table for Years of life lost due to premature mortality and population, incidence estimates (Spanish tumour registries and fitting of generalized linear mixed models, duration (from data of survival in Spain from the EUROCARE-3 study and fitting of Weibull distribution function and disability (weights published in the literature for Years lost due to disability. Results There were 828,997 DALYs due to cancer (20.5 DALYs/1,000 population, 61% in men. Of the total, 51% corresponded to lung, colorectal, breast, stomach and prostate cancers. Mortality (84% of DALYs predominated over disability. Subjects aged under 20 years accounted for 1.6% and those aged over 70 years accounted for 30.1% of DALYs. Conclusion Lung, colorectal and breast cancers are responsible for the highest number of DALYs in Spain. Even if the burden of disease due to cancer is predominantly caused by mortality, some cancers have a significant weight of disability. Information on 2000 burden of disease due to cancer can be useful to assess how it has evolved over time and the impact of medical advances on it in terms of mortality and disability.

    The extent of taxation and redistribution policy is generally determined at a political-economy equilibrium by a balance between those who gain and those who lose from a more extensive tax-transfer policy. In a stylized model of migration and human capital formation we find, somewhat against conventional wisdom, that low-skill migration may lead to a lower tax burden and less redistribution than without migration, even though the migrants (naturally) join the pro-tax cum transfer coalition.

  17. Burden sharing in the implementation of the Climate Convention

    International Nuclear Information System (INIS)

    Burden sharing in the actions needed to reduce greenhouse gas emissions has proved so far to be the most intractable problem in the implementation of the Climate Convention and the Kyoto Protocol. We analyzed the contribution of non-Annex I countries to the GHG emissions in the period 1850–2010 to assess their relative contribution to total GHG emissions. In the period 1850–1990 non-Annex I countries represented 44% of the total but this contribution increased in the period 1990–2010 to 56%. If we extrapolate present trends to 2030 they will represent 69% in the period 1990–2030. The “historical responsibility” of Annex I countries is therefore decreasing. If we take 1990 as the starting year in which the Climate Convention recognized clearly that greenhouse gases are interfering dangerously with the climate system, it is evident the need of non-Annex I countries to engage with Annex I countries in the effort to reduce emissions. We present three options for the burden sharing in such effort. -- Highlights: •Implementation of the Kyoto Protocol did not reduce global GHG emissions growth. •Defining burden sharing of emissions is key to the success of climate negotiations. •Accounting for historical emissions involves too many uncertainties. •Developed countries have already presented pledges to reduce their emissions by 2020. •Emissions of developing countries became dominant and they must act to reduce them

    Full Text Available Cysticercosis is an infection of tissues with the larval cysts of the cestode, Taenia  solium. While live parasites elicit little or no inflammation, dying parasites initiate a granulomatous reaction presenting as painful muscle nodules or seizures when cysts are located in the brain. We previously showed in the T. crassiceps murine model of cysticercosis that substance P (SP, a neuropeptide, was detected in early granulomas and was responsible for promoting granuloma formation, while somatostatin (SOM, another neuropeptide and immunomodulatory hormone, was detected in late granulomas; SOM’s contribution to granuloma formation was not examined. In the current studies, we used somatostatin knockout (SOM−/− mice to examine the hypothesis that SOM downmodulates granulomatous inflammation in cysticercosis, thereby promoting parasite growth. Our results demonstrated that parasite burden was reduced 5.9-fold in SOM−/− mice compared to WT mice (P<0.05. This reduction in parasite burden in SOM−/− mice was accompanied by a 95% increase in size of their granulomas (P<0.05, which contained a 1.5-fold increase in levels of IFN-γ and a 26-fold decrease in levels of IL-1β (P<0.05 for both compared to granulomas from WT mice. Thus, SOM regulates both parasite burden and granulomatous inflammation perhaps through modulating granuloma production of IFN-γ and IL-1β.

    15 years after its first democratic election, South Africa is in the midst of a profound health transition that is characterised by a quadruple burden of communicable, non-communicable, perinatal and maternal, and injury-related disorders. Non-communicable diseases are emerging in both rural and urban areas, most prominently in poor people living in urban settings, and are resulting in increasing pressure on acute and chronic health-care services. Major factors include demographic change leading to a rise in the proportion of people older than 60 years, despite the negative effect of HIV/AIDS on life expectancy. The burden of these diseases will probably increase as the roll-out of antiretroviral therapy takes effect and reduces mortality from HIV/AIDS. The scale of the challenge posed by the combined and growing burden of HIV/AIDS and non-communicable diseases demands an extraordinary response that South Africa is well able to provide. Concerted action is needed to strengthen the district-based primary health-care system, to integrate the care of chronic diseases and management of risk factors, to develop a national surveillance system, and to apply interventions of proven cost-effectiveness in the primary and secondary prevention of such diseases within populations and health services. We urge the launching of a national initiative to establish sites of service excellence in urban and rural settings throughout South Africa to trial, assess, and implement integrated care interventions for chronic infectious and non-communicable diseases.

    The main objective of this systematic review was to evaluate the economic burden of Herpes Zoster (HZ) infection.   The review was conducted in accordance with the standards of the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The following databases were accessed: ISI/Web of Knowledge (WoS), MEDLINE/PubMed, Scopus, ProQuest, the Cochrane Library and EconLit. Specific literature on health economics was also manually inspected. Thirty-three studies were included. The quality of the studies assessed in accordance with the Consolidated Health Economic Evaluation Reporting Standards checklist was good. All studies evaluated direct costs, apart from one which dealt only with indirect costs. Indirect costs were evaluated by 12 studies. The economic burden of HZ has increased over time. HZ management and drug prescriptions generate the highest direct costs. While increasing age, co-morbidities and drug treatment were found to predict higher direct costs, being employed was correlated with higher indirect costs, and thus with the onset age of the disease. Despite some differences among the selected studies, particularly with regard to indirect costs, all concur that HZ is a widespread disease which has a heavy social and economic burden.

    In North Africa, overnutrition has dramatically increased with the nutrition transition while micronutrient deficiencies persist, resulting in clustering of opposite types of malnutrition that can present a unique difficulty for public health interventions. We assessed the magnitude of the double burden of malnutrition among urban Moroccan and Tunisian women, as defined by the coexistence of overall or central adiposity and anemia or iron deficiency (ID), and explored the sociodemographic patterning of individual double burden. In cross-sectional surveys representative of the region around the capital city, we randomly selected 811 and 1689 nonpregnant women aged 20-49 y in Morocco and Tunisia, respectively. Four double burdens were analyzed: overweight (body mass index ≥25 kg/m(2)) or increased risk abdominal obesity (waist circumference ≥80 cm) and anemia (blood hemoglobin education groups. Generally, the rare, associated sociodemographic factors varied across the 4 subject-level double burdens and the 2 countries and differed from those usually associated with adiposity, anemia, or ID. Any double burden combining adiposity and anemia or ID should therefore be taken into consideration in all women. This trial was registered at clinicaltrials.gov as NCT01844349. PMID:24198310

    2014-12-01

    Full Text Available The inferences of burden metallization rate on softening-melting dropping properties were investigated through softening-melting dropping test of three kinds of metalized burden pressure drop. The results indicated that the softeningmelting temperature interval of pre-reduction mixed burden is bigger than primeval mixed burden, the melting interval narrow with the rise of metallization rate of ferric burden as well as dropping temperature interval. The average pressure drop, maximum pressure drop and softening-melting dropping properties eigenvalue decrease with the rise of metallization rate of ferric burden. Besides, the dropping temperature of burden reduces with the rise of carbon content of molten iron. The combination high metalized burden and higher carbon content of molten iron is benefit to decreasing thickness of cohesive zone and improve permeability of cohesive zone.

  3. The global burden of mental, neurological and substance use disorders: an analysis from the Global Burden of Disease Study 2010.

    Harvey A Whiteford

    Full Text Available The Global Burden of Disease Study 2010 (GBD 2010, estimated that a substantial proportion of the world's disease burden came from mental, neurological and substance use disorders. In this paper, we used GBD 2010 data to investigate time, year, region and age specific trends in burden due to mental, neurological and substance use disorders.For each disorder, prevalence data were assembled from systematic literature reviews. DisMod-MR, a Bayesian meta-regression tool, was used to model prevalence by country, region, age, sex and year. Prevalence data were combined with disability weights derived from survey data to estimate years lived with disability (YLDs. Years lost to premature mortality (YLLs were estimated by multiplying deaths occurring as a result of a given disorder by the reference standard life expectancy at the age death occurred. Disability-adjusted life years (DALYs were computed as the sum of YLDs and YLLs.In 2010, mental, neurological and substance use disorders accounted for 10.4% of global DALYs, 2.3% of global YLLs and, 28.5% of global YLDs, making them the leading cause of YLDs. Mental disorders accounted for the largest proportion of DALYs (56.7%, followed by neurological disorders (28.6% and substance use disorders (14.7%. DALYs peaked in early adulthood for mental and substance use disorders but were more consistent across age for neurological disorders. Females accounted for more DALYs in all mental and neurological disorders, except for mental disorders occurring in childhood, schizophrenia, substance use disorders, Parkinson's disease and epilepsy where males accounted for more DALYs. Overall DALYs were highest in Eastern Europe/Central Asia and lowest in East Asia/the Pacific.Mental, neurological and substance use disorders contribute to a significant proportion of disease burden. Health systems can respond by implementing established, cost effective interventions, or by supporting the research necessary to develop

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

  5. Renewable energy burden sharing. REBUS. Effects of burden sharing and certificate trade on the renewable electricity market in Europe

    International Nuclear Information System (INIS)

    Creation of an internal market for renewable electricity will involve a political negotiation process, similar to previous European Union (EU) greenhouse gas negotiations. The Energy Ministers in the EU have agreed upon an overall target of 22% of electricity supply from Renewable Energy Sources (RES-E) and a distribution of targets over the individual Member States. The REBUS project provides insights in the effects of implementing targets for renewable electricity generation at EU Member State level and the impact of introducing burden sharing systems within the EU, such as a Tradable Green Certificate (TGC) system. Member States can participate in such burden sharing systems to reduce the costs of achieving RES-E targets. The project concentrated on the development of the REBUS model, which quantifies the impact of trade (in green certificates, quotas or targets), the specification of cost potential curves for renewable electricity options in each of the 15 EU Member States and the implementation of different rules to setting targets at individual Member State level. In addition, utilities and consumer organisations were interviewed on their requirements and expectations for an international burden sharing scheme. 49 refs

    A comparative examination of potential differences in selenium (Se) sensitivity was conducted on two sturgeon species indigenous to the San Francisco Bay-Delta. Juvenile green (Acipenser medirostris), recently given a federally threatened status, and white sturgeon (Acipenser transmontanus) were exposed to one of four nominal concentrations of dietary l-selenomethionine (SeMet) (0 (control), 50, 100, or 200 mg SeMet/kg diet) for 8 weeks. Mortality, growth performance, whole body composition, histopathology, and Se burdens of the whole body, liver, kidneys, gills, heart, and white muscle were determined every 2 to 4 weeks. Significant (pkidneys and liver of both sturgeon species; however, green sturgeon was more susceptible to SeMet than white sturgeon at all dietary SeMet levels. Our results showed that a dietary Se concentration at 19.7 ± 0.6 mg Se/kg, which is in range with the reported Se concentrations of the benthic macro-vertebrate community of the San Francisco Bay, had adverse effects on both sturgeon species. However, the exposure had a more severe pathological effect on green sturgeon, suggesting that when implementing conservation measures, this federally listed threatened species should be monitored and managed independently from white sturgeon.

    Dissatisfaction with physical appearance and body image is a common psychological phenomena in Western society. Body image dissatisfaction is frequently reported by those who have excess body weight, but also is seen in those of normal body weight. For both groups of individuals, this dissatisfaction impacts self-esteem and quality of life. Furthermore, it is believed to be the motivational catalyst to a range of appearance-enhancing behaviors, including weight loss efforts and physical activity. Body image dissatisfaction is also believed to play a role in the decision to seek the wide range of body contouring procedures offered by aesthetic physicians. Individuals who seek these procedures typically report increased body image dissatisfaction, focus on the feature they wish to alter with treatment, and often experience improvement in body image following treatment. At the same time, extreme body image dissatisfaction is a symptom of a number of recognized psychiatric disorders. These include anorexia nervosa, bulimia nervosa, and body dysmorphic disorder (BDD), all of which can contraindicate aesthetic treatment. This special topic review paper provides an overview of the relationship between body image dissatisfaction and aesthetic procedures designed to improve body contouring. The review specifically focuses on the relationship of body image and body weight, as well as the presentation of body image psychopathology that would contraindicate aesthetic surgery. The overall goal of the paper is to highlight the clinical implications of the existing research and provide suggestions for future research on the psychological aspects of body contouring procedures.

  17. Microphysical simulations of sulfur burdens from stratospheric sulfur geoengineering

    J. M. English

    2012-01-01

    Full Text Available Recent microphysical studies suggest that geoengineering by continuous stratospheric injection of SO2 gas may be limited by the growth of the aerosols. We study the efficacy of SO2, H2SO4 and aerosol injections on aerosol mass and optical depth using a three-dimensional general circulation model with sulfur chemistry and sectional aerosol microphysics (WACCM/CARMA. We find increasing injection rates of SO2 in a narrow band around the equator to have limited efficacy while broadening the injecting zone as well as injecting particles instead of SO2 gas increases the sulfate burden for a given injection rate, in agreement with previous work. We find that injecting H2SO4 gas instead of SO2 does not discernibly alter sulfate size or mass, in contrast with a previous study using a plume model with a microphysical model. However, the physics and chemistry in aircraft plumes, which are smaller than climate model grid cells, need to be more carefully considered. We find equatorial injections increase aerosol optical depth in the Northern Hemisphere more than the Southern Hemisphere, potentially inducing regional climate changes. We also find significant perturbations to tropospheric aerosol for all injections studied, particularly in the upper troposphere and near the poles, where sulfate burden increases by up to 100 times. This enhanced burden could have implications for tropospheric radiative forcing and chemistry. These results highlight the need to mitigate greenhouse gas emissions through means other than geoengineering, and to further study geoengineering before it can be seriously considered as a climate intervention option.

  19. The geographical distribution and burden of trachoma in Africa.

    Directory of Open Access Journals (Sweden)

    Jennifer L Smith

    Full Text Available There remains a lack of epidemiological data on the geographical distribution of trachoma to support global mapping and scale up of interventions for the elimination of trachoma. The Global Atlas of Trachoma (GAT was launched in 2011 to address these needs and provide standardised, updated and accessible maps. This paper uses data included in the GAT to describe the geographical distribution and burden of trachoma in Africa.Data assembly used structured searches of published and unpublished literature to identify cross-sectional epidemiological data on the burden of trachoma since 1980. Survey data were abstracted into a standardised database and mapped using geographical information systems (GIS software. The characteristics of all surveys were summarized by country according to data source, time period, and survey methodology. Estimates of the current population at risk were calculated for each country and stratified by endemicity class.At the time of writing, 1342 records are included in the database representing surveys conducted between 1985 and 2012. These data were provided by direct contact with national control programmes and academic researchers (67%, peer-reviewed publications (17% and unpublished reports or theses (16%. Prevalence data on active trachoma are available in 29 of the 33 countries in Africa classified as endemic for trachoma, and 1095 (20.6% districts have representative data collected through population-based prevalence surveys. The highest prevalence of active trachoma and trichiasis remains in the Sahel area of West Africa and Savannah areas of East and Central Africa and an estimated 129.4 million people live in areas of Africa confirmed to be trachoma endemic.The Global Atlas of Trachoma provides the most contemporary and comprehensive summary of the burden of trachoma within Africa. The GAT highlights where future mapping is required and provides an important planning tool for scale-up and surveillance of trachoma

  20. Rota Viral Infection: A Significant Disease Burden to Libya.

    Full Text Available Rotavirus is a common infection causing 450,000 deaths annually primarily in children 5 years and below. Despite the high burden of disease, little is known about the epidemiology of rotavirus in Libya. The aim of this study was to estimate the rotavirus disease burden among Libyan children.A cross-sectional study was carried out prospectively among children 5 years old and below between August 2012 and April 2013. Stool samples of children with diarrhea attending the outpatient department or admitted to the pediatric wards, at three public hospitals within the northwestern region of Libya were tested for rotavirus. The seasonality, symptomology demographics and outcomes of rotavirus cases were determined and compared to other diarrhea illnesses. An estimated incidence rate per 100,000 children aged 5 years and below was determined.A total of 545 children with diarrhea were identified for participation. Results of rotavirus immunoassays determined 57% of cases were caused by rotavirus. Inpatients were more likely to be rotavirus positive than outpatients (58% vs. 53%, P<0.05, Most rotavirus positive cases (86% were found among children below 2 years of age. Rotaviral cases peaked in the winter, constituting 76% of diarrheal illness in February and very few rotavirus cases in the summer months. The incidence rate of rotavirus diarrhea was estimated at 640/100,000 children aged 5 years and below.Rotavirus infection poses a significant disease burden in Libya. Preventive measures such as proper hygiene should be emphasized. Introduction of vaccination against rotavirus into the national immunization program should be examined, as it would likely be a cost-effective investment.

    Impetigo and scabies both present different challenges in resource-limited compared with industrialised settings. Severe complications of these skin infections are common in resource-limited settings, where the burden of disease is highest. The microbiology, risk factors for disease, diagnostic approaches and availability and suitability of therapies also vary according to setting. Taking this into account we aim to summarise recent data on the epidemiology of impetigo and scabies and describe the current evidence around approaches to individual and community based treatment.

    2016-09-01

    Neurofibromatosis type 1 (NF1) is a hereditary tumor syndrome caused by mutations of the NF1 gene and resulting dysregulation of the Ras-pathway. In addition to peripheral nerve tumors, affected tissues include the musculoskeletal and cardiovascular system. The immune system has recently been suggested as a possible modulator NF1-related phenotypes. Therefore, we determined the immune phenotype in NF1 patients and investigated its relationship with the phenotypic severity of NF1-related tumor manifestations. We quantified global leukocytes and lymphocyte subpopulations of peripheral blood from 37 NF1 patients and 21 healthy controls by flow cytometry. To associate immune phenotype with tumor phenotype, all NF1 patients underwent whole-body magnetic resonance imaging and total internal tumor volume was calculated. The immunophenotypes were compared among four NF1 groups with different total internal tumor burdens and between NF1 patients and non-NF1 subjects. We found that NF1 patients show a generalized lymphopenia. Closer analysis revealed that the CD8(+)/CD27(-) and CD8(+)/CD57(+) effector T cell fractions strongly increase in NF1 patients with low tumor load and decrease to levels below control in patients with high tumor load. Moreover, increased production of IL2, IFN-γ and TNF-α was found in T cells of NF1 patients upon phorbol-12-myristate acetate (PMA) stimulation compared to healthy controls. The data indicate that decreasing CD8(+)/CD57(+) and CD27(-) T cell fractions correspond to increasing tumor load in NF1 patients, potentially making these populations useful marker for internal tumor burden.

Median liver stiffness was 6.2 kPA; 72.9% had no evidence of or mild stiffness, 14.5% had moderate stiffness, and 12.6% had evidence of severe stiffness/cirrhosis. Prevalence of severe stiffness/cirrhosis was significantly higher among persons who were older, had a longer duration of injecting drugs, higher body mass index, higher prevalence of insulin resistance, higher prevalence of steatosis, higher HCV RNA levels and evidence of alcohol dependence. An estimated 42.1% of severe stiffness/cirrhosis in this sample was attributable to HCV. 529 (53.0% had some evidence of steatosis. Prevalence of steatosis was higher among those who had larger waist circumference, insulin resistance, higher HDL cholesterol and a history of antiretroviral therapy.We observed a high burden of liver disease in this relatively young cohort that was primarily driven by chronic HCV infection, metabolic factors (insulin resistance and steatosis and heavy alcohol use. Interventions to improve access to HCV treatment and reduce alcohol use are needed to prevent further progression of liver disease.

  7. Monitoring of thorium incorporation by thoron in breath measurement: Methodology improvements and determination of burdens of workers

    International Nuclear Information System (INIS)

    Thorium body burdens were determined from thoron (220Rn) in breath measurements: decay products of expired 220Rn were collected electrostatically and their progeny were subsequently measured by alpha-spectrometry. The volume of the 38.5 litre collection chamber was optimised with respect to the breathing rate, the decay constant of thoron, the electric field geometry and strength, and the humidity of air. Calibration was achieved by means of a calibrated 228Th source. A minimum detectable activity of 45 mBq 224Ra freely emanating 220Rn at the mouth (Ra equivalent) was achieved. Five Thorotrast patients were measured and data ranged from 40 up to 150 Bq Ra equivalent, indicating an exhalation factor of about 4.0 ± 1.9% of the total 220Rn produced in the body. Data from 53 workers showed burdens up to 23 Bq (mean 5.5 Bq) of thorium. Urine bioassays of samples from the same workers yielded corresponding results. In vivo measurements revealed no result above the detection limit of 25 Bq 208Tl. (author)

  8. Thyroidal burdens of 129I from various dietary sources

    International Nuclear Information System (INIS)

    Thyroidal burdens of 129I were calculated for 1-, 4- and 14-yr-olds, and adults, using available dietary data. Milk and milk products contributed 63, 57, 54 and 33% of the total thyroidal 129I burden of the four respective age groups. As the contribution from dairy products decreased, that from meat increased from about 12% for 1-yr-olds to 35% for adults, while that from leafy vegetables remained relatively stable, from 17 to 21%. From ingested foods produced in air assumed to contain 1 pCi 129I per m3, daily dietary 129I intakes of 1.3, 1.2, 1.7 and 1.5 nCi were computed for the 1-, 4-, and 14-yr-old child and adult, respectively. For each nCi ingested daily, thyroidal dose rates for the respective age groups were calculated to be 4.9, 2.1, 1.7 and 2.6 rem/yr, with the altered dose rates reflecting age-related differences in thyroid gland size and iodine kinetics.

    Efficient operation of iron blast furnaces requires that the iron bearing burden material have good reduction, softening and melting characteristics. These characteristics are determined by the physical operation of the blast furnace and the mineralogical composition of the agglomerate. Increasing oil injection rates will increase the hydrogen content of the reducing gas significantly. The aim of this work is to establish how different burden materials react to this change in gas environment, and develop sinters which have optimal properties. The testing of sinter and pellets is broken into two areas: development of the test methods; and determination of sinter and pellet characteristics. The test method requires development because recent testwork has shown that the reducibility of the sinter is now so high that the reduction under load test is no longer sensitive. A new control program and more realistic gas compositions are currently being tested. The softening and melting characteristics of sinters of varying composition, acid pellets and olivine pellets have been tested using the reduction under load test at Rautaruukki Oy Research Centre. The effect of hydrogen in the reducing gas on the different iron ore agglomerates has been evaluated SULA 2 Research Programme; 6 refs.

  10. Environmental Benefits and Burdens of Phosphorus Recovery from Municipal Wastewater.

    The environmental benefits and burdens of phosphorus recovery in four centralized and two decentralized municipal wastewater systems were compared using life cycle assessment (LCA). In centralized systems, phosphorus recovered as struvite from the solids dewatering liquid resulted in an environmental benefit except for the terrestrial ecotoxicity and freshwater eutrophication impact categories, with power and chemical use offset by operational savings and avoided fertilizer production. Chemical-based phosphorus recovery, however, generally required more resources than were offset by avoided fertilizers, resulting in a net environmental burden. In decentralized systems, phosphorus recovery via urine source separation reduced the global warming and ozone depletion potentials but increased terrestrial ecotoxicity and salinization potentials due to application of untreated urine to land. Overall, mineral depletion and eutrophication are well-documented arguments for phosphorus recovery; however, phosphorus recovery does not necessarily present a net environmental benefit. While avoided fertilizer production does reduce potential impacts, phosphorus recovery does not necessarily offset the resources consumed in the process. LCA results indicate that selection of an appropriate phosphorus recovery method should consider both local conditions and other environmental impacts, including global warming, ozone depletion, toxicity, and salinization, in addition to eutrophication and mineral depletion impacts.

  11. Air pollution burden of illness from traffic in Toronto

    International Nuclear Information System (INIS)

    This paper examined the health impacts of air pollution from traffic in Toronto. The paper provided a review of scientific studies on the health effects of vehicle pollution as well as a quantitative assessment of the economic costs and the burden of illness attributed to traffic pollution in Toronto. The report also assessed air pollution and traffic trends in the city, and outlined initiatives being conducted to reduce vehicle-related pollution. The study used the new air quality benefits tool (AQBAT) which determines the burden of illness and the economic impacts of traffic-related air pollution. Air modelling specialists were consulted in order to determine the contribution of traffic-related pollutants to overall pollution levels using data on traffic counts and vehicle emissions factors. The air model also considered dispersion, transport and and the transformation of compounds emitted from vehicles. Results of the study showed that traffic pollution caused approximately 440 premature deaths and 1700 hospitalizations per year. Children in the city experienced more than 1200 acute bronchitis episodes per year as a result of air pollution from traffic. Mortality-related costs associated with traffic pollution in Toronto were estimated at $2.2 billion. It was concluded that the city must pursue the implementation of sustainable transportation policies and programs which foster and enable the expansion and use of public transport. 47 refs., 8 tabs., 9 figs

  13. Quality assurance: a burden or an essential tool for management?

    International Nuclear Information System (INIS)

    The role of Quality Assurance in nuclear power plant management is discussed. Customer's satisfaction has always been considered by the supplier as a key factor to achieve his company's prosperity, provided that this satisfaction can be obtained in proper economical conditions. According to ISO standards, to satisfy the customer's need is in fact the definition of quality. Some twenty years ago nuclear safety introduced an additional notion: an evidence of satisfaction of customer's needs shall be provided - this is the Quality Assurance. Many companies on which this requirement was imposed experienced it and, in some cases continue to experience it, as an additional burden, due to the customer's lack of confidence. However, Code 50.C.QA clearly states in its introduction that Quality Assurance is an essential aspect of good management. It is very difficult to segregate the Quality Assurance Programme implementation efficiency from the company management efficiency. The arguments contained in the paper result in the following possible answer to the question in the title: a burden and an essential tool for management. (Z.S.)

  14. The burden and management of dyslipidemia: practical issues.

    The objective of this study is to describe briefly the burden of dyslipidemia, and to discuss and present strategies for health professionals to improve dyslipidemia management, based on a review of selected literature focusing on interventions for dyslipidemia treatment adherence. Despite the availability of effective lifestyle and pharmaceutical therapies for dyslipidemias, they continue to present a significant economic burden in the United States. Adherence to evidence-based guidelines for the treatment of dyslipidemias is unsatisfactory. The reasons for medication nonadherence are complex and specific to each patient. The lack of progress in achieving optimal lipid targets is caused by many factors: patient (medication adherence, cost of medication, literacy), medication (adverse effects, complexity of regimen), provider (lack of adherence to evidence-based practice guidelines, poor communication), and the US healthcare system (being focused on acute care rather than prevention, lack of continuity of care, general lack of use of an electronic health record). Combined interventions that target each part of the system have been effective in improving treatment adherence and achieving lipid goals. Patients, providers, pharmacists, and employers all play a role in management of dyslipidemia. No single approach will solve the complex issue of improving dyslipidemia management. The required lifestyle changes are known and effective medications are available. The challenge is for all interested parties-including nurses, nurse practitioners, doctors, pharmacists, other health care professionals, employers, and health plans-to help patients achieve behavioral changes.

    From 81 volunteers (16 without dental restorations, 65 with gold crowns or inlays) samples of saliva before and after chewing gum, blood, serum, urine and faeces were taken and analysed for gold (Au) and palladium (Pd). The Au concentration in all analysed biomonitors correlates significantly to the number of teeth with gold restorations. For Pd the correlations were still significant, but weaker than for Au. Persons with gold restorations show maximal Au and Pd concentrations, 10(2)-10(3) higher than the background burden. The calculated maximal daily Au load in saliva (1.38 mg Au per day) reaches the range of an oral Au therapy for rheumatoid arthritis with 6 mg Auranofin (= 1.74 mg Au per day). During this therapy severe and frequent side effects are reported. In contrast, the Au concentration in serum maximally reached from Au restorations, amounts to only approximately 1/20 of the Au level during arthritis therapy. But even under subtherapeutic doses of 1 mg Auranofin/day severe side effects have been reported (4 out of 56 cases). The mean Au blood concentration from 1 mg Auranofin daily was only 3 times higher than our maximum value. A toxicological classification of the Pd values is difficult, because no toxicological threshold limit has been established, especially for the low-level long-term burden with Pd.

    Arsenic contamination of rice by irrigation with contaminated groundwater and secondarily increased soil arsenic compounds the arsenic burden of populations dependent on subsistence rice-diets. The arsenic concentration of cooked rice is known to increase with the arsenic concentration of the cooking water but the effects of cooking methods have not been defined. We tested the three major rice cooking procedures followed globally. Using low-arsenic water (As rice: water::1:6; discard excess water) removed up to 57% of the arsenic from rice containing arsenic 203-540 microg/kg. Approximately half of the arsenic was lost in the wash water, half in the discard water. A simple inexpensive rice cooker based on this method has been designed and used for this purpose. Despite the use of low-arsenic water, the contemporary method of cooking unwashed rice at rice:water::1:1.5-2.0 until no discard water remains did not modify the arsenic content. Preliminary washing until clear did remove 28% of the rice arsenic. The results were not influenced by water source (tubewell, dug well, pond or rain); cooking vessel (aluminium, steel, glass or earthenware); or the absolute weight of rice or volume of water. The use of low-As water in the traditional preparation of arsenic contaminated rice can reduce the ingested burden of arsenic. PMID:16876928

    In Brazil, human fungal infections are prevalent, however, these conditions are not officially reportable diseases. To estimate the burden of serious fungal diseases in 1 year in Brazil, based on available data and published literature. Historical official data from fungal diseases were collected from Brazilian Unified Health System Informatics Department (DATASUS). For fungal diseases for which no official data were available, assumptions of frequencies were made by estimating based on published literature. The incidence (/1000) of hospital admissions for coccidioidomycosis was 7.12; for histoplasmosis, 2.19; and for paracoccidioidomycosis, 7.99. The estimated number of cryptococcal meningoencephalitis cases was 6832. Also, there were 4115 cases of Pneumocystis pneumonia in AIDS patients per year, 1 010 465 aspergillosis and 2 981 416 cases of serious Candida infections, including invasive and non-invasive diseases. In this study, we demonstrate that more than 3.8 million individuals in Brazil may be suffering from serious fungal infections, mostly patients with malignant cancers, transplant recipients, asthma, previous tuberculosis, HIV infection and those living in endemic areas for truly pathogenic fungi. The scientific community and the governmental agencies should work in close collaboration in order to reduce the burden of such complex, difficult-to-diagnose and hard to treat diseases.

    Dengue, the world's most important mosquito-borne viral disease, is endemic in the Philippines. During 2008–2012, the country's Department of Health reported an annual average of 117,065 dengue cases, placing the country fourth in dengue burden in southeast Asia. This study estimates the country's annual number of dengue episodes and their economic cost. Our comparison of cases between active and passive surveillance in Punta Princesa, Cebu City yielded an expansion factor of 7.2, close to the predicted value (7.0) based on the country's health system. We estimated an annual average of 842,867 clinically diagnosed dengue cases, with direct medical costs (in 2012 US dollars) of $345 million ($3.26 per capita). This is 54% higher than an earlier estimate without Philippines-specific costs. Ambulatory settings treated 35% of cases (representing 10% of direct costs), whereas inpatient hospitals served 65% of cases (representing 90% of direct costs). The economic burden of dengue in the Philippines is substantial. PMID:25510723

  19. A comparability analysis of global burden sharing GHG reduction scenarios

    International Nuclear Information System (INIS)

    The distribution of the mitigation burden across countries is a key issue regarding the post-2012 global climate policies. This article explores the economic implications of alternative allocation rules, an assessment made in the run-up to the COP15 in Copenhagen (December 2009). We analyse the comparability of the allocations across countries based on four single indicators: GDP per capita, GHG emissions per GDP, GHG emission trends in the recent past, and population growth. The multi-sectoral computable general equilibrium model of the global economy, GEM-E3, is used for that purpose. Further, the article also compares a perfect carbon market without transaction costs with the case of a gradually developing carbon market, i.e. a carbon market with (gradually diminishing) transaction costs. - Highlights: ► Burden sharing of global mitigation efforts should consider equity and efficiency. ► The comparability of allocations across countries is based on four indicators. ► The four indicators are GDP/capita, GHG/GDP, population growth, and GHG trend. ► Any possible agreement on effort comparability needs a combination of indicators. ► We analyse the role played by the degree of flexibility in global carbon trading

    Full Text Available Background: The aim of this study was to assess the economic burden of fire-related injury from two perspectives: post-injury social security compensations and also productivity losses due to the lost productive time from a societal perspective induced by the injury. Design and methods: A cohort of 1503 inpatients who sustained firerelated injury during the period 2001–2005 was retrospectively followed up for 5-10 years until the end of 2010, using linkages between several administrative registers. The study process was started in 2015 and finalized on March 2016. Results: Annual productivity loss was on average EUR 5.72 million, giving a total for the five-year study period of EUR 28.6 million, with a mean value of EUR 19,070 per person. Mean/median disability time for those who received benefits was 572/63 days, ranging from 3 days to 36.5 years. Total average cost of benefits to the injured annually during the study period was EUR 1.03 million. This equates to EUR 3430 per patient for the whole cohort or EUR 14,860 for those who received benefits. Conclusions: The burden of fire-related injuries in terms of payment transfers and lost productivity due to periods of disability as indirect costs is high; in a population of 5.4 million, the annual loss exceeded EUR 5.7 million. The results could be used in planning preventive measures and therefore yield savings

    Full Text Available Background: Cardiovascular diseases are viewed worldwide as one of the main causes of death.This study aims to report the burden of ischemic heart diseases (IHDs in Iran by using data of the global burden of disease (GBD study, 1990-2010. Materials and Methods: The GBD study 2010 was a systematic effort to provide comprehensive data to calculate disability-adjusted life years (DALYs for diseases and injuries in the world. Years of life lost (YLLs due to premature mortality were computed on the basis of cause-of-death estimates, using Cause of Death Ensemble model (CODEm. Years lived with disability (YLDs were assessed by the multiplication of prevalence, the disability weight for a sequel, and the duration of symptoms. A systematic review of published and unpublished data was performed to evaluate the distribution of diseases, and consequently prevalence estimates were calculated with a Bayesian meta-regression method (DisMod-MR. Data from population-based surveys were used for producing disability weights. Uncertainty from all inputs into the calculations of DALYs was disseminated by Monte Carlo simulation techniques. Results: The age-standardized IHDs DALY specified rate decreased 31.25% over 20 years from 1990 to 2010 [from 4720 (95% uncertainty interval (UI: 4,341-5,099 to 3,245 (95% UI: 2,810-3,529 person-years per 100,000]. The decrease were 38.14% among women and 26.87% among men. The age-standardized IHDs death specefied rate decreased by 21.17% [from 222 95% UI: 207-243 (to 175 (95% UI:152-190 person-years per 100,000] in both the sexes. The age-standardized YLL and YLD rates decreased 32.05% and 4.28%, respectively, in the above period. Conclusion: Despite decreasing age-standardized IHD of mortality, YLL, YLD, and DALY rates from 1990 to 2010, population growth and aging increased the global burden of IHD. YLL has decreased more than IHD deaths and YLD since 1990 but IHD mortality remains the greatest contributor to disease burden.

    Full Text Available Abstract Background The objective of this study was to estimate the burden of disease and injury in Iran for the year 2003, using Disability-Adjusted Life Years (DALYs at the national level and for six selected provinces. Methods Methods developed by the World Health Organization for National Burden of Disease (NBD studies were applied to estimate disease and injury incidence for the calculation of Years of Life Lost due to premature mortality (YLL, Years Lived with Disability (YLD, and DALYs. The following adjustments of the NBD methodology were made in this study: a revised list with 213 disease and injury causes, development of new and more specific disease modeling templates for cancers and injuries, and adjustment for dependent comorbidity. We compared the results with World Health Organization (WHO estimates for Eastern Mediterranean Region, sub-region B in 2002. Results We estimated that in the year 2003, there were 21,572 DALYs due to all diseases and injuries per 100,000 Iranian people of all ages and both sexes. From this total number of DALYs, 62% were due to disability premature deaths (YLD and 38% were due to premature deaths (YLL; 58% were due to noncommunicable diseases, 28% – to injuries, and 14% – to communicable, maternal, perinatal, and nutritional conditions. Fifty-three percent of the total number of 14.349 million DALYs in Iran were in males, with 36.5% of the total due to intentional and unintentional injuries, 15% due to mental and behavioral disorders, and 10% due to circulatory system diseases; and 47% of DALYs were in females, with 18% of the total due to mental and behavioral disorders, 18% due to intentional and unintentional injuries, and 12% due to circulatory system diseases. The disease and injury causes leading to the highest number of DALYs in males were road traffic accidents (1.071 million, natural disasters (548 thousand, opioid use (510 thousand, and ischemic heart disease (434 thousand.

    Full Text Available Background. Home care for patients with Multiple Sclerosis (MS relies largely on informal caregivers (ICs. Methods. We assessed ICs objective burden (Resource Utilization in Dementia measuring informal care time (ICT and ICs subjective burden (Zarit Burden Inventory (ZBI. Results. ICs (N=99 were spouses (70%, mean age 52 years, assisting disabled patients with a mean EDSS (Expanded Disability Status Scale of 5.5, with executive dysfunction (mean DEX (Dysexecutive questionnaire of 25 and a duration of MS ranging from 1 to 44 years. Objective burden was high (mean ICT = 6.5 hours/day, mostly consisting of supervision time. Subjective burden was moderate (mean ZBI = 27.3. Multivariate analyses showed that both burdens were positively correlated with higher levels of EDSS and DEX, whereas coresidency and IC’s female gender correlated with objective burden only and IC’s poor mental health status with subjective burden only. When considering MS aggressiveness, it appeared that both burdens were not correlated with a higher duration of MS but rather increased for patients with severe and early dysexecutive function and for patients classified as fast progressors according to the Multiple Sclerosis Severity Score. Conclusion. Evaluation of MS disability course and IC’s personal situation is crucial to understand the burden process and to implement adequate interventions in MS.

This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

  9. Preventing or reducing the Cs-137 burden in children

    International Nuclear Information System (INIS)

    Full text: The Helsinki Agreements impose intervention when a diagnosed disease can be cured or prevented. Since 1998 members of IPPNW Switzerland study health related problems due to the Chernobyl Fallout in the Ukraine and Belarus. The organisation furthermore finances diagnostic and radiometric activities, as measuring the Cs-137 burden in the organism. Also preventive measures are supported in cooperation with the french NGO 'Children of Chernobyl Belarus'. The Clinical Research Institute of Radiation Medicine and Endocrinology and the Gomel' State Med. Institute found correlations between chronic excess of Cs-137 and genetic, congenital, endocrine, immunological, cardiovascular, gastrointestinal, ophthalmologic anomalies and cancer. For etiological assessment the correlation between pathology and internal irradiation requires repeated measuring of Cs-137 burden. Anthropo-Gammametry measures of the mean Cs-137 load of the organism, which can be done in a few minutes. These values, however, cannot be used to directly calculate the dose to a given organ, as cesium concentrations may vary from 1 to 100 in the same child. Very low values of Cs-137 are found in skin and fatty tissue; in small children the highest concentrations are found in endocrine glands, pancreas, thymus and heart. Cs-137 is a gamma and beta emitting isotope. Whereas in the environment gamma emissions are important, once ingested beta emissions within millimeter distance are more damaging for cellular structures than gamma rays. Neurons of given brain structures localized in the left hemisphere (in right handed persons) also seem to be susceptible to ionizing radiations. There appear to be correlations with certain mental diseases and disorders, including schizophrenia and chronic fatigue syndrome. As regards to practical radiation protection, unfortunately families in rural areas rely on their own foodstuffs and milk and poor families frequently consume highly contaminated natural products.

    The consumption of alcoholic beverages is harmful to human health. In recent years, consumption patterns of alcoholic beverages have changed in our society, and binge drinking has generalized. It is considered to be a socio-sanitary problem with few known consequences in terms of individual and third-party social impacts(in the form of violence or traffic accidents) and its organic impact(affects the liver and other organs and systems, such as the nervous and cardiovascular systems) and represents an important financial burden due to its increasing economic impact. This review provides a global approach to binge drinking and emphasizes its epidemiological character, the effect of this type of consumption and the possible management of a problem with an increasing tendency in our society.

  11. Palm: Easing the Burden of Analytical Performance Modeling

    Energy Technology Data Exchange (ETDEWEB)

    Tallent, Nathan R.; Hoisie, Adolfy

    2014-06-01

    Analytical (predictive) application performance models are critical for diagnosing performance-limiting resources, optimizing systems, and designing machines. Creating models, however, is difficult because they must be both accurate and concise. To ease the burden of performance modeling, we developed Palm, a modeling tool that combines top-down (human-provided) semantic insight with bottom-up static and dynamic analysis. To express insight, Palm defines a source code modeling annotation language. By coordinating models and source code, Palm's models are `first-class' and reproducible. Unlike prior work, Palm formally links models, functions, and measurements. As a result, Palm (a) uses functions to either abstract or express complexity (b) generates hierarchical models (representing an application's static and dynamic structure); and (c) automatically incorporates measurements to focus attention, represent constant behavior, and validate models. We discuss generating models for three different applications.

  12. Crime and punishment: the economic burden of impunity

    Crime is an economically relevant activity. It may represent a mechanism of wealth distribution but also a social and economic burden because of the interference with regular legal activities and the cost of the law enforcement system. Sometimes it may be less costly for the society to allow for some level of criminality. However, a drawback of such a policy is that it may lead to a high increase of criminal activity, that may become hard to reduce later on. Here we investigate the level of law enforcement required to keep crime within acceptable limits. A sharp phase transition is observed as a function of the probability of punishment. We also analyze other consequences of criminality as the growth of the economy, the inequality in the wealth distribution (the Gini coefficient) and other relevant quantities under different scenarios of criminal activity and probabilities of apprehension.

  13. Burden of disease of dietary exposure to acrylamide in Denmark

    2016-01-01

    Acrylamide (AA) is a process-contaminant that potentially increases the risk of developing cancer in humans. AA is formed during heat treatment of starchy foods and detected in a wide range of commonly consumed products. Increased focus on risk ranking and prioritization of major causes of disease...... makes it relevant to estimate the impact that exposure to chemical contaminants and other hazards in food have on health. In this study, we estimated the burden of disease (BoD) caused by dietary exposure to AA, using disability adjusted life years (DALY) as health metric.We applied an exposure...... due to exposure to AA through foods, as estimated by the most conservative approach.This result should be used to inform risk management decisions and for comparison with BoD of other food-borne hazards for prioritizing policies. However, our study shows that careful evaluation of methodological...

    The number of hepatitis C virus (HCV) infections is projected to decline while those with advanced liver disease will increase. A modeling approach was used to forecast two treatment scenarios: (i) the impact of increased treatment efficacy while keeping the number of treated patients constant...... and (ii) increasing efficacy and treatment rate. This analysis suggests that successful diagnosis and treatment of a small proportion of patients can contribute significantly to the reduction of disease burden in the countries studied. The largest reduction in HCV-related morbidity and mortality occurs...... when increased treatment is combined with higher efficacy therapies, generally in combination with increased diagnosis. With a treatment rate of approximately 10%, this analysis suggests it is possible to achieve elimination of HCV (defined as a >90% decline in total infections by 2030). However...

    2015-01-01

    The cancers in the digestive system including gastric cancer, colorectal cancer, liver cancer, esophageal cancer and pancreatic cancer are one of the most common cancers in Asia. The burden of GI cancer is increasing in Asia because of aging, growth of the population and the risk factors including smoking, obesity, changing lifestyle and high prevalence of H pylori, HBV and HCV. In most Asian countries, cancer control programs or early detection and treatment services are limited despite this increase. There are many people in the developing countries inside Asia who have no health insurance and many of them are too poor to go for screening tests, early detection or medical treatments. Therefore, it is important for the health organizations and governments in each country to recognize these groups and reduce the incidence and mortality of gastrointestinal cancers, using simple and economic screening test, vaccination and changing risk factors such as smoking, diet and lifestyle by education programs.

    Inadequate attention given to the management of asthma and ways of improving treatment could be a significant factor for the increase morbidity and mortality from asthma despite major advances in our understanding of the pathophysiology of the disease. There seems to be paucity of data concerning the management pattern and burden of asthma in Africa. This study was under taken to determine the prevalence, management pattern and the burden of asthma. This study was a cross sectional design involving clinical and lung function assessment. The diagnosis of asthma was made using the clinical features of asthma and lung function parameters (Forced expiratory volume in one second, Peak expiratory flow rate, Reversibility tests). Totally, 120 asthma patients participated in this study. All subjects completed the clinical asthma control questionnaires. All items were rated with the calculation of their mean and percentages. Student t-test was used to calculate the difference between the mean of the lung function tests for subjects and control. The prevalence of asthma among respiratory unit patients was 6.6% and higher in the first three decades of life with female preponderance (F:M=1.5-1).There is a strong family history of asthma(81.7%). Associated allergies include rhinitis (75%), pharyngitis (54%), conjunctivitis (54%) and dermatitis (30%). Percentage of asthma patients treated with bronchodilators alone (70%), combined inhaled bronchodilators and steroid (28.3%). Impaired daily activities include sports (84%), Job career (60%), Physical activity (55%), Social activity (54%), Household chores (61%), Disturbed sleep (53%), Daytime symptoms (51%), Hospitalized(50%). Subjects had significant low lung function values when compared with control (P asthma is very high despite the advanced knowledge of the pathophysiology and management of asthma.

    Seligman, Benjamin J.; Cullen, Mark R.; Horwitz, Ralph I.

    2011-01-01

    Background The World Health Organization's Global Burden of Disease (GBD) reports are an important tool for global health policy makers, however the accuracy of estimates for countries undergoing an epidemiologic transition is unclear. We attempted to validate the life table model used to generate estimates for all-cause mortality in developing countries. Methods and Results Data were obtained for males and females from the Human Mortality Database for all countries with available data every ten years from 1900 to 2000. These provided inputs for the GBD life table model and served as comparison observed data. Above age sixty model estimates of survival for both sexes differed substantially from those observed. Prior to the year 1960 for males and 1930 for females, estimated survival tended to be greater than observed; following 1960 for both males and females estimated survival tended to be less than observed. Viewing observed and estimated survival separately, observed survival past sixty increased over the years considered. For males, the increase was from a mean (sd) probability of 0.22 (0.06) to 0.46 (0.1). For females, the increase was from 0.26 (0.06) to 0.65 (0.08). By contrast, estimated survival past sixty decreased over the same period. Among males, estimated survival probability declined from 0.54 (0.2) to 0.09 (0.06). Among females, the decline was from 0.36 (0.12) to 0.15 (0.08). Conclusions These results show that the GBD mortality model did not accurately estimate survival at older ages as developed countries transitioned in the twentieth century and may be similarly flawed in developing countries now undergoing transition. Estimates of the size of older-age populations and their attributable disease burden should be reconsidered. PMID:21629652

  3. Dependence and caregiver burden in Alzheimer's disease and mild cognitive impairment.

    Gallagher, Damien

    2011-03-01

    The dependence scale has been designed to be sensitive to the overall care needs of the patient and is considered distinct from standard measures of functional ability in this regard. Little is known regarding the relationship between patient dependence and caregiver burden. We recruited 100 patients with Alzheimer\\'s disease or mild cognitive impairment and their caregivers through a memory clinic. Patient function, dependence, hours of care, cognition, neuropsychiatric symptoms, and caregiver burden were assessed. Dependence was significantly correlated with caregiver burden. Functional decline and dependence were most predictive of caregiver burden in patients with mild impairment while behavioral symptoms were most predictive in patients with moderate to severe disease. The dependence scale demonstrated good utility as a predictor of caregiver burden. Interventions to reduce caregiver burden should address patient dependence, functional decline, and behavioral symptoms while successful management of the latter becomes more critical with disease progression.

    "Body" is a basic concept of both the natural and human sciences. This extensive review of the literature explores the various philosophical approaches to the body, including empiricism, idealism, existentialism and phenomenology, as well as the relationship between body and mind. Embodiment and body image are the two main concepts of body addressed in this article. Merleau-Ponty's perspective on embodiment, an important new area of theory development, emphasizes that embodiment research must focus on life experiences, such as the study of body image. Using Schilder's framework of psychosocialology, this article provides a comprehensive understanding of the concept of body image and women's perspectives on the "body" in both Western culture and Eastern cultures. Body size and shape significantly influence the self-image of women. Body image is something that develops and changes throughout one's life span and is continually being constructed, destructed, and reconstructed. Personal body image has important psychological effects on the individual, especially women. This integrative review can make a significant contribution to knowledge in this area and, consequently, to related practice and research.

    2014-05-01

    Globally, the rate at which maternal overweight and obesity increase with rising wealth is higher than the accompanying decline in the prevalence of child stunting, resulting in the double burden of malnutrition. The positive association between household wealth and child linear growth is larger in households with a more educated mother. However, whether a similar positive and synergistic association between maternal education and household wealth is observed for maternal body weight is unknown. Our objective was to assess the potential protective role of maternal education in the etiology of the double burden of malnutrition (stunted child with an overweight mother). We used data on 1547 nonpregnant mothers (aged 18-49 y) and their children (aged 0-5 y) collected in a cross-sectional survey in 235 rural communities in southern Mexico. Child height-for-age Z-score and maternal body weight were regressed on household wealth, women's schooling, and the interaction between both, controlling for relevant covariates. A similar model was used for the prevalence of double-burden pairs (stunted child with an overweight mother). In mothers with less than primary school, a doubling in wealth was not associated with improved child's height but was associated with an increase in mother's weight (3.7%, P child height-for-age Z-score (0.32 SD, P Mexico. Where maternal schooling is low, poverty reduction must be accompanied by effective behavior change communication to prevent child stunting and to protect women from unhealthy weight gain.

    {beta}-Thalassaemia major is a hereditary haemolytic anaemia that is treated with multiple blood transfusions. A major complication of this treatment is iron overload, which leads to cell death and organ dysfunction. Chelation therapy, used for iron elimination, requires effective monitoring of the body burden of iron, for which serum ferritin levels and liver iron content measured in liver biopsies are used as markers, but are not reliable. MRI based on iron-induced T2 relaxation enhancement can be used for the evaluation of tissue siderosis. Various MR protocols using signal intensity ratio and mainstream relaxometry methods have been used, sometimes with discrepant results. Relaxometry methods using multiple echoes achieve better sampling of the time domain in which relaxation mechanisms take place and lead to more precise results. In several studies the MRI parameters of liver siderosis have failed to correlate with those of other affected organs, underlining the necessity for MRI iron evaluation in individual organs. Most studies have included children in the evaluated population, but MRI data on very young children are lacking. Wider application of relaxometry methods is indicated, with the establishment of universally accepted MRI protocols, and further studies, including young children, are needed. (orig.)

    Estimating survival in amyotrophic lateral sclerosis (ALS) is challenging due to heterogeneity in clinical features of disease and a lack of suitable markers that predict survival. Our aim was to determine whether scoring of upper or lower motor neuron weakness is associated with survival. With this objective, 161 ALS subjects were recruited from two tertiary referral centres. Scoring of upper (UMN) and lower motor neuron (LMN) signs was performed, in addition to a brief questionnaire. Subjects were then followed until the censorship date. Univariate analysis was performed to identify variables associated with survival to either non-invasive ventilation (NIV) or death, which were then further characterized using Cox regression. Results showed that factors associated with reduced survival included older age, bulbar and respiratory involvement and shorter diagnostic delay (all p < 0.05). Whole body LMN score was strongly associated with time to NIV or death (p ≤0.001) whereas UMN scores were poorly associated with survival. In conclusion, our results suggest that, early in disease assessment and in the context of other factors (age, bulbar, respiratory status), the burden of LMN weakness provides an accurate estimate of outcome. Such a scoring system could predict prognosis, and thereby aid in selection of patients for clinical trials. PMID:26700804

    Full Text Available Background. Chronic pain is associated with increased morbidity and mortality, predominated by cardiovascular disease and cancer. Investigating related risk factor measures may elucidate the biological burden of chronic pain. Objectives. We hypothesized that chronic pain severity would be positively associated with the risk factor composite. Methods. Data from 12,982 participants in the 6th Tromsø study were analyzed. Questionnaires included demographics, health behaviors, medical comorbidities, and chronic pain symptoms. The risk factor composite was comprised of body mass index, fibrinogen, C-reactive protein, and triglycerides. Chronic pain severity was characterized by frequency, intensity, time/duration, and total number of pain sites. Results. Individuals with chronic pain had a greater risk factor composite than individuals without chronic pain controlling for covariates and after excluding inflammation-related health conditions (p<0.001. A significant “dose-response” relationship was demonstrated with pain severity (p<0.001. In individuals with chronic pain, the risk factor composite varied by health behavior, exercise, lower levels and smoking, and higher levels. Discussion. The risk factor composite was higher in individuals with chronic pain, greater with increasing pain severity, and influenced by health behaviors. Conclusions. Identification of a biological composite sensitive to pain severity and adaptive/maladaptive behaviors would have significant clinical and research utility.

This study aimed at providing insight on this burden across France, Germany, Italy, Spain, and the UK, considering direct and indirect costs, productivity loss, and humanistic impact on patients and their families. Methods: Physician questionnaires provided data on patients presenting with NP covering demographics, sick leave and retirement, number of consultations, drug treatments, and surgical procedures. Patients provided further demographic and disease-related data and completed the Work Productivity and Activity Impairment (WPAI, the EuroQol 5-Dimension (EQ-5D, and the Brief Pain Inventory (BPI questionnaires. All health-related direct unitary costs were collected from relevant country-specific sources and adjusted to 2012 prices (€ where necessary. A subgroup analysis of costs based on diabetic peripheral neuropathy (n=894, fibromyalgia (n=300, and low back pain (n=963 was performed. Findings: About 413 physicians completed a total of 3,956 patient records forms. Total annual direct health-care costs per patient ranged from €1,939 (Italy to €3,131 (Spain. Annual professional caregiver costs ranged from €393 (France to €1,242 (UK, but this only represented a small proportion of total care because much care is provided by family or friends. Sick leave costs ranged from €5,492 (UK to €7,098 (France, with 10%–32% patients prevented from working at some point by NP. Total cost (including direct and indirect costs of NP per patient was €10,313 in France (69% of the total cost, €14,446 in Germany (78%, €9,305 in Italy (69%, €10,597 in Spain (67%, and €9,685 in the UK (57%.

    Full Text Available Abstract Background Child injury is recognized as a global health problem. Injuries caused the highest burden of disease among the total population of Iran in 2003. We aimed to estimate the morbidity, mortality, and disease burden caused by child injuries in the 0- to 14-year-old population of Iran in 2005. Methods We estimated average age- and sex-specific mortality rates for different types of child injuries from 2001 to 2006 using Iran's death registration data. Incidence rates for nonfatal outcomes of child injuries in 2005 were estimated through a time- and place-limited sample hospital registry study for injuries. We used the World Health Organization's methods for estimation of years of life lost due to premature mortality and years lived with disability in 2005. Results Injuries were the most important cause of death in children ages 1 to 14, with 35, 33.4, 24.9, and 22.9 deaths per 100,000 in the 0-14, 1-4, 5-9, and 10-14 age groups respectively. Road transport injuries were responsible for the highest death rate per 100,000 population among all types of injuries in children, with 15.5 for ages 0-14, 16.1 for ages 1-4, 16.3 for ages 5-9, and 13.1 for ages 10-14. Incidence rates of injuries leading to hospitalization were 459, 530, and 439 per 100,000 in the 0-14, 1-4, and 5-14 age groups respectively. Incidence rates of injuries leading to outpatient care were 1,812, 2,390, and 1,650 per 100,000 in the same age groups respectively. Among injury types, falls and burns had the highest hospitalization and outpatient care incidence rates. Conclusions Injuries, particularly road transport injuries, were the most important health problem of children in Iran in 2003 and 2005. Strong social policy is needed to ensure child survival.

    AIM: To estimate the burden of undiagnosed celiac disease (CD) in the Mediterranean area in terms of morbidity, mortality and health cost. METHODS: For statistics regarding the population of each country in the Mediterranean area, we accessed authoritative international sources (World Bank, World Health Organization and United Nations). The prevalence of CD was obtained for most countries from published reports. An overall prevalence rate of 1% cases/total population was finally estimated to represent the frequency of the disease in the area, since none of the available confidence intervals of the reported rates significantly excluded this rate. The distribution of symptoms and complications was obtained from reliable reports in the same cohort. A standardized mortality rate of 1.8 was obtained from recent reports. Crude health cost was estimated for the years between symptoms and diagnosis for adults and children, and was standardized for purchasing power parity to account for the different economic profiles amongst Mediterranean countries.RESULTS: In the next 10 years, the Mediterranean area will have about half a billion inhabitants, of which 120 million will be children. The projected number of CD diagnoses in 2020 is 5 million cases (1 million celiac children), with a relative increase of 11% compared to 2010. Based on the 2010 rate, there will be about 550 000 symptomatic adults and about 240 000 sick children: 85% of the symptomatic patients will suffer from gastrointestinal complaints, 40% are likely to have anemia, 30% will likely have osteopenia, 20% of children will have short stature, and 10% will have abnormal liver enzymes. The estimated standardized medical costs for symptomatic celiac patients during the delay between symptom onset and diagnosis (mean 6 years for adults, 2 years for children) will be about €4 billion (€387 million for children) over the next 10 years. A delay in diagnosis is expected to increase mortal ity: about 600 000 celiac

    Full Text Available OBJECTIVES: The goal of this study is: (1 to estimate the current direct out-of-pocket (OOP and indirect non-communicable diseases (NCD burden on Indonesian households and (2 to project NCD prevalence and burden in 2020 focusing specifically on hypertension, diabetes, heart problems and stroke. METHODS: This study relies on econometric analyses based on four waves of the Indonesian Family Life Survey (IFLS. RESULTS: In aggregate, of the NCDs studied, heart problems exert the greatest economic burden on households, costing Int$1.56 billion in OOP and indirect burden in 2010. This was followed by hypertension (Int$1.36 billion, diabetes (Int$0.81 billion and stroke (Int$0.29 billion. The OOP and indirect burden of these conditions is estimated to be Int$4.02 billion. Diabetes and stroke are expected to have the largest proportional increases in burden by 2020; 56.0% for diabetes and 56.9% for stroke to total Int$1.27 billion and Int$0.45 billion respectively. The burden of heart problems in 2020 is expected to increase by 34.4% to total Int$2.09 billion and hypertension burden will increase by 46.1% to Int$1.99 billion. In 2020, these conditions are expected to impose an economic burden of Int$5.80 billion. CONCLUSION: In conclusion, this study demonstrates the significant burden of 4 primary NCDs on Indonesian households. In addition to the indirect burden, hypertension, diabetes, heart problems and stroke account for 8% of the nation's OOP healthcare expenditure, and due to rising disease prevalence and an aging population, this figure is expected to increase to 12% by 2020 without a significant health intervention.

    Renata Šmit

    Full Text Available Tick-borne encephalitis (TBE presents an increasing burden in many parts of Europe, Asian Russia, Siberia, Asian former USSR and Far East. Incidence can be considered as one way to express the burden. A more comprehensive measure concerns disability-adjusted life years (DALYs, better characterizing the full burden of TBE. TBE burden in DALYs has not yet been estimated, nor has it been specified by the Global Burden of Disease (GBD studies.The purpose of the present study is to estimate the burden of TBE in Slovenia, expressed in DALYs, both from the population and individual perspectives. We discuss the impact of TBE burden on public health and potential strategies to reduce this burden in Slovenia.The burden of TBE is estimated by using the updated DALYs' methodology first introduced in the GBD project. The DALYs᾽ calculations are based on the health outcomes of the natural course of the disease being modelled. Corrections for under-reporting and under-ascertainment are applied. The impact of uncertainty in parameters in the model was assessed using sensitivity analyses.From the population perspective, total DALYs amount to 3,450 (167.8 per 100,000 population, while from the individual perspective they amount to 3.1 per case in 2011. Notably, the consequences of TBE present a larger burden than TBE itself.TBE presents a relatively high burden expressed in DALYs compared with estimates for other infectious diseases from the GBD 2010 study for Slovenia. Raising awareness and increasing vaccination coverage are needed to reduce TBE and its consequences.

    Full Text Available Background: Family caregiver is the most important person who cares for patient with schizophrenia. However when care is provided for long time, he/she may experiences the burden.Purpose: The purpose was to review concept and factors related to burden on family caregivers caring for patients with schizophrenia.Method: A literatures were searched from databases: Pubmed, CINAHL, and Science Direct. Key words used to retrieve literature include caregiver burden and schizophrenia. Searching was limited in English language, full text, and the year of publication from 2000 to 2009 was used.Results: Twenty two studies were reviewed in this paper. The result showed that the caregivers caring for patients with schizophrenia experience burden. Burden was defined as a negative impact of caring for the impaired person experienced by caregiver on their activity (objective burden or feeling (subjective burden that involves emotional, physical health, social life, and financial status. Factors related to burden on family caregiver were grouped into: 1 caregiver‟s factors included age, gender, educational level, income, health status, and spent time per day, knowledge of schizophrenia, culture, and coping; 2 patient‟s factors included age, clinical symptoms, and disability in daily life; 3 environmental factors included mental health service and social support.Conclusion: Definition of burden have quite same meaning and mostly factors focus on the patient‟s symptoms, demographic factors of caregiver, and time spent per day. Most of studies cannot be generalized due to small sample used in the study and that too conducted in western countries. For further research, the correlation between burden and resources of family caregiver should be investigated particularly in eastern country.Key words: burden on family caregiver, caring, schizophrenia.

    Concentrations of Al and Fe were determined in samples of filamentous algae, bryophytes and invertebrates from 24 stream sites in North Westland, South Island, New Zealand. Sites were variably contaminated by acid coal mine drainage and ranged in pH from 2.6 to 6.2. Conductivity of stream water ranged from 16 to 944 {mu}S{sub 25} cm{sup -1} and maximum concentrations of total dissolved Al and total Fe measured in two successive years were 35.5 and 32.6 mg l{sup -1}, respectively. Metal burdens of algae and bryophytes were not correlated with pH, conductivity or the concentrations of Al and Fe observed in stream water. Metal concentrations in invertebrates were significantly lower than those in plants (mg per g dry wt.), and were similar in herbivore-detritivores (mainly mayfly larvae) and carnivorous species. No evidence was found for the biomagnification of either metal within aquatic food webs. However, invertebrate species exposed to very high concentrations of Al and Fe varied considerably in body burdens, suggesting that groups of insects differ considerably in their physiological or morphological ability to exclude potentially toxic metals.

    Southern hemisphere humpback whales undertake the longest migrations and associated periods of fasting of any mammal. Fluctuations in lipid energy stores are known to profoundly affect the toxicokinetics of lipophilic organochlorine compound (OC) burdens. Results from blubber biopsy sampling of adult, male humpback whales at two time points of the annual migration journey revealed dramatic concentration effects for the majority of OC compounds. The observed concentration effect was, however, not linear with measured average blubber lipid loss indicating significant redistribution of OCs and hence the importance of alternate lipid depots for meeting the energetic demands of the migration journey. Applying lipophilic OC burdens as novel tracers of whole-body lipid dynamics, the observed average concentration index suggests an average individual weight loss of 13% over 4 months of the migration journey. This value is based upon lipid derived energy and is in good agreement with previous weight prediction formulas. Notably, however, these estimates may greatly underestimate individual weight loss if significant protein catabolism occurs. Biomagnification factors between migrating southern hemisphere humpback whales and their principal prey item, Antarctic krill, closely resembled those of baleen whales feeding on herbivorous zooplankton in the Arctic. This study emphasizes the importance of considering prolonged periods of food deprivation when assessing chemical risks posed to wildlife. This is of particular importance for Polar biota adapted to extremes in ecosystem productivity. PMID:23859482

    Full Text Available Abstract Background Chronic immune thrombocytopenia (ITP is a debilitating autoimmune disorder that causes a reduction in blood platelets and increased risk of bleeding. ITP is currently managed with various pharmacologic therapies and splenectomy. This study was conducted to assess patient perceived and reported treatment side effects, as well as the perceived burden or bother, and need to reduce or stop treatment, associated with these side effects among adult patients with chronic ITP. Methods A Web-enabled survey was administered to members of a US-based ITP patient support group. Patients reported demographic and clinical characteristics, ITP treatments' side effects for treatments received since diagnosed, level of bother (or distress, and need to reduce or stop treatment, associated with side effects. Current and past exposure was assessed for five specific treatment types: corticosteroids (CS, intravenous immunoglobulin (IVIg, anti-D immunoglobulin (anti-D, rituximab (RT, and splenectomy (SPL, as well as for other patient-referenced therapies (captured as "other". Results The survey was completed by 589 patients; 78% female, 89% white, mean age 48 years (SD = 14.71, and 68% reported a typical low platelet count of P P P P Conclusions Current ITP treatments, particularly corticosteroids, are associated with multiple bothersome side effects that may lead to patients stopping or reducing therapy. Open, informed and complete communication between clinician and patient regarding both the benefits and the side effects of ITP treatment may better prepare patients for their prescribed regimens.

An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.Keywords: otitis media, costs, societal burden, Portugal

    ABSTRACT Despite ACIP recommendation and cost-effectiveness established in those 19–59 y old diabetes patients the uptake of Hepatitis B vaccine in diabetes patients is low. There is need to highlight the impact of Hepatitis B virus (HBV) infection in diabetes patients in terms of healthcare utilization and costs to recognize the burden of HBV in this population. This retrospective claims analysis included patients with diabetes and HBV (cases; n=1,236) and those with diabetes without HBV (controls; n=4,944), identified by ICD-9-CM diagnosis codes. Cases were matched with 4 controls using propensity score matching. Healthcare utilization and cost were compared; incremental effect of HBV infection was assessed using multivariate analysis. In the adjusted analyses, the mean number of hospitalizations (0.6 vs 0.4), outpatient service visits (34.2 vs. 20.4), and office visits (10.9 vs. 9.8) were 41%, 68%, and 11% higher, respectively, in cases vs. controls (all ppharmacy costs ($8,029 vs. $5,114) were both significantly higher for cases (p < 0.0001). Healthcare utilization and costs were higher among patients with diabetes and HBV than in those with diabetes alone. These results provide evidence supporting the need for HBV vaccination among unvaccinated diabetes patients. PMID:27050021

    The objective of this study was to evaluate the economic and humanistic burden of chronic sleep maintenance insomnia characterized by nighttime awakenings (CINA). A database analysis of National Health and Wellness Survey, an annual cross-sectional study of health status and outcomes of US adults, was performed. CINA was defined as experiencing nighttime awakenings at least twice per week for more than 1 month that have moderate to severe impact on daily life and not experiencing difficulty falling asleep. No insomnia was defined as not self-reporting insomnia, sleep difficulties, or sleep symptoms. Outcomes included resource utilization in the past 6 months, the Work Productivity and Activity Impairment questionnaire, and the SF-8. Linear regression models were developed to assess the independent effects of CINA on outcomes while controlling for demographics and comorbidity. In all, 1523 respondents met the criteria for CINA and 24,106 met the criteria for no insomnia.

    Irritable bowel syndrome affects approximately 10-15% of the European population, although prevalence rates vary depending on the classification used and the country surveyed. This may be due to differences in patterns of medical care and diagnosis of the condition. Up to 70% of individuals with irritable bowel syndrome may not have been formally diagnosed. The disorder affects 1.5-3 times as many women as men and poses a significant economic burden in Europe, estimated at euro 700-euro 1600 per person per year. It also reduces quality of life and is associated with psychological distress, disturbed work and sleep, and sexual dysfunction. It is a chronic disorder, which affects many individuals for more than 10 years. Most patients are managed in primary care, although some are referred to gastroenterologists and other specialists. Patients with irritable bowel syndrome undergo more abdomino-pelvic surgery than the general population. We propose that a positive diagnosis of the condition may avoid the delay in diagnosis many patients experience. We conclude that, in Europe, there are significant unmet needs including lack of familiarity with irritable bowel syndrome, difficulties in diagnosis and lack of effective treatments for the multiple symptoms of the disorder. The development of pan-European guidelines for irritable bowel syndrome will benefit patients with this condition in Europe.

    Primary spontaneous pneumothorax (PSP) occurs most frequently in young, tall, lean, male smokers without any known underlying lung disease. It is an important diagnosis to make promptly in order to prevent progression to obstructive shock. We present a case report of a young, male, former-smoker and polysubstance abuser with no prior lung history that developed acute dyspnea at rest and was found to have a large right pneumothorax on chest x-ray. A pig-tail catheter was utilized, but his course was complicated by a recurrent tension pneumothorax. Chest computed tomography (CT) revealed a significant bleb burden and the patient underwent a lung wedge resection with mechanical pleurodesis. What made our case unique were the chest x-rays revealing blebs that could have predicted the patient's recurrent pneumothorax as well as the multiple potential risk factors for developing blebs and a pneumothorax. All patients with recurrent PSPs and those with higher risk initial PSPs (e.g. blebs) should undergo preventive therapy with pleurodesis. We hope that clinicians can benefit from utilizing these representative chest x-ray images showing blebs. PMID:27642566

  6. The global burden of IBD: from 2015 to 2025.

    Over 1 million residents in the USA and 2.5 million in Europe are estimated to have IBD, with substantial costs for health care. These estimates do not factor in the 'real' price of IBD, which can impede career aspirations, instil social stigma and impair quality of life in patients. The majority of patients are diagnosed early in life and the incidence continues to rise; therefore, the effect of IBD on health-care systems will rise exponentially. Moreover, IBD has emerged in newly industrialized countries in Asia, South America and Middle East and has evolved into a global disease with rising prevalence in every continent. Understanding the worldwide epidemiological patterns of IBD will prepare us to manage the burden of IBD over time. The goal of this article is to establish the current epidemiology of IBD in the Western world, contrast it with the increase in IBD in newly industrialized countries and forecast the global effects of IBD in 2025.

    Morbidity and complexity involved in lymph node staging via surgical resection and biopsy calls for staging techniques that are less invasive. While visible blue dyes are commonly used in locating sentinel lymph nodes, since they follow tumor-draining lymphatic vessels, they do not provide a metric to evaluate presence of cancer. An area of active research is to use fluorescent dyes to assess tumor burden of sentinel and secondary lymph nodes. The goal of this work was to successfully deploy and test an intra-nodal cancer-cell injection model to enable planar fluorescence imaging of a clinically relevant blue dye, specifically methylene blue along with a cancer targeting tracer, Affibody labeled with IRDYE800CW and subsequently segregate tumor-bearing from normal lymph nodes. This direct-injection based tumor model was employed in athymic rats (6 normal, 4 controls, 6 cancer-bearing), where luciferase-expressing breast cancer cells were injected into axillary lymph nodes. Tumor presence in nodes was confirmed by bioluminescence imaging before and after fluorescence imaging. Lymphatic uptake from the injection site (intradermal on forepaw) to lymph node was imaged at approximately 2 frames/minute. Large variability was observed within each cohort.

    Acrylamide (AA) is a process-contaminant that potentially increases the risk of developing cancer in humans. AA is formed during heat treatment of starchy foods and detected in a wide range of commonly consumed products. Increased focus on risk ranking and prioritization of major causes of disease makes it relevant to estimate the impact that exposure to chemical contaminants and other hazards in food have on health. In this study, we estimated the burden of disease (BoD) caused by dietary exposure to AA, using disability adjusted life years (DALY) as health metric. We applied an exposure-based approach and proposed a model of three components: an exposure, health-outcome, and DALY-module. We estimated BoD using two approaches for estimating cancer risk based on toxicological data and two approaches for estimating DALY. In Denmark, 1.8 healthy life years per 100.000 inhabitants are lost each year due to exposure to AA through foods, as estimated by the most conservative approach. This result should be used to inform risk management decisions and for comparison with BoD of other food-borne hazards for prioritizing policies. However, our study shows that careful evaluation of methodological choices and assumptions used in BoD studies is necessary before use in policy making.

    2016-06-24

    Tuberculosis (TB) is a leading cause of morbidity and mortality worldwide, accounting for about 9.6 million new cases and 1.5 million deaths annually. The poorest and socially excluded groups carry the largest burden of disease, which makes it essential to properly address the social determinants of health through poverty reduction measures and targeted interventions on high-risk populations. The spread of multidrug-resistance TB requires special attention and highlights the need to foster research on TB diagnostics, new drugs and vaccines. Although many advances have been made in the fight against TB over the last twenty years, a lot is still needed to achieve global elimination. The new end-TB strategy that was first launched in 2014 by the World Health Organization, is fully in line with the seventeen Sustainable Development Goals that came into effect since January 2016 and sets ambitious goals for the post-2015 agenda. A 90% reduction in TB-related mortality and an 80% decline in TB incidence within 2030 as well as the abolition of catastrophic expenditures for TB-affected people are the main targets of this strategy. Strong government commitment and adequate financing from all countries together with community engagement and appropriate investments in research are necessary in order to reach these objectives.

    Full Text Available Background: Controversy persists as to the need for both MIBG and bone scanning in routine evaluation of neuroblastoma. Aim: To compare the efficacy of I-131- metaiodobenzylguanidine (MIBG scan against that of conventional Tc99m- methylene diphosphonate (MDP bone scan for the detection of skeletal deposition of neuroblastoma. Methods and Material: The study included 57 patients (36 boys, 21 girls: age range 1-14 years of neuroblastoma who underwent both bone scan with Tc99m-MDP and I-131-MIBG scan within 15 days of each other at presentation and during follow-up. Results: At presentation 11(19.2% patients had evidence of skeletal metastases on MDP scan against 7 patients who showed bony secondaries on MIBG scan. Of the 7 patients, with positive MIBG and MDP scans, MDP scan detected 11 sites whereas MIBG scan detected 7 sites. On follow-up study, 3 patients with initial abnormal MDP scan but normal MIBG scan, developed skeletal metastases detectable on MIBG scan, whereas 3 of the 46 patients who had normal MDP and MIBG scan at presentation; developed skeletal metastases detectable on MDP scan. MIBG scan was concordant in 2 of them but was normal in the third patient. Conclusion: I-131-MIBG underestimates skeletal disease burden in neuroblastoma. Therefore, Tc99m-MDP bone scan should remain a part of routine assessment of patients with neuroblastoma.

    2006-11-01

    The looming epidemic of stroke and other chronic non-communicable diseases associated with lifestyle and demographic transitions occurring all over the world is increasingly being acknowledged. However, the significance of these trends in the relatively young populations of the countries comprising Sub-Saharan Africa (SSA) is less certain and considerably overshadowed by attention given to the impact of human immunodeficiency virus and other infectious diseases. We undertook a literature review of the burden of stroke in SSA and provide recommendations for future research. Despite the paucity of high quality studies, the mostly hospital-based data and limited community surveys indicate there to be high and increasing rates of stroke affecting people at much younger ages in SSA than in developed countries. In general, awareness, diagnosis and management of stroke are poor, and the associated case fatality and residual disability are high. As elsewhere, elevated blood pressure is the major determinant of stroke but there are also high rates of strokes related to the complications of rheumatic heart disease and other infections. Given high attributable risks exposures in association with rapid ageing and urbanisation in SSA, the future is not bright. Population-based incidence studies are urgently needed to map the profile and outcome of stroke. Such data would provide the necessary evidence base to improve prevention and treatments for stroke alongside current efforts to bring infectious diseases under control in SSA. PMID:18706015

    Full Text Available Neural tube defects (NTDs, serious birth defects of the brain and spine usually resulting in death or paralysis, affect an estimated 300,000 births each year worldwide. Although the majority of NTDs are preventable with adequate folic acid consumption during the preconception period and throughout the first few weeks of gestation, many populations, in particular those in low and middle resource settings, do not have access to fortified foods or vitamin supplements containing folic acid. Further, accurate birth defects surveillance data, which could help inform mandatory fortification and other NTD prevention initiatives, are lacking in many of these settings. The burden of birth defects in South East Asia is among the highest in the world. Expanding global neural tube defects prevention initiatives can support the achievement of the United Nations Millennium Development Goal 4 to reduce child mortality, a goal which many countries in South East Asia are currently not poised to reach, and the 63rd World Health Assembly Resolution on birth defects. More work is needed to develop and implement mandatory folic acid fortification policies, as well as supplementation programs in countries where the reach of fortification is limited.

    Full Text Available Hans Verstraelen,1 Eline De Zutter,1 Martine De Muynck2 1Department of Obstetrics and Gynaecology, Vulvovaginal Disease Clinic, Ghent University Hospital, Ghent, Belgium; 2Department of Physical Medicine and Rehabilitation, Ghent University Hospital, Ghent, Belgium Abstract: The vulva is a particularly common locus of chronic pain with neuropathic characteristics that occurs in women of any age, though most women with neuropathic type chronic vulvar pain will remain undiagnosed even following multiple physician visits. Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain. Keywords: vulvar pain, genitofemoral nerve, neuropathic pain, vulvodynia, vulvar disease

    2015-06-01

    The objective of this study was to estimate the economic costs of posttraumatic stress disorder (PTSD) among the Northern Ireland (NI) adult population. The authors present a prevalence-based, bottom-up study based primarily on data from 1,986 participants in the Northern Ireland Study of Health and Stress (NISHS). Both direct costs of treatment and indirect costs of productivity losses were included. Units of service and medication resource use were obtained from the NISHS and combined with their relevant unit costs from the Personal Social Services Research Unit and Prescription Costs Analysis data for NI. Indirect costs included the costs of incapacity days due to PTSD and presenteeism costs, with gender-specific wage rates used as the relevant unit costs. The total direct and indirect cost of PTSD in NI (2008) was £172,756,062. This figure is likely to be conservative due to the exclusion of a number of cost categories. Nevertheless, comparison of estimates of the burden of PTSD with the estimated cost of treating all adults with PTSD with the recommended treatments shows the potential for substantial economic gains to be made through extension and investment in effective evidence-based treatments.

    AIM To investigate the potential burden of nonalcoholicsteatohepatitis (NASH) and advanced fibrosis in ahispanic community.METHODS: Four hundred and forty two participantswith available ultrasonography data from the CameronCounty Hispanic Cohort were included in this study. Eachparticipant completed a comprehensive questionnaireregarding basic demographic information, medicalhistory, medication use, and social and family historyincluding alcohol use. Values of the nonalcoholic fattyliver disease fibrosis score (NFS), FIB4 index, BARDscore, and Aspartate aminotransferase to Platelet RatioIndex (APRI) were computed using the blood samplescollected within 6 mo of liver ultrasonography fromeach participant. Hepatic steatosis was determinedby ultrasonography. As part of univariable analysis,for continuous variables, comparisons among groupswere performed with student-t test, one way analysisof variance, and Mann-Whitney test. Pearson χ 2 andthe Fisher exact test are used to assess differencesin categorical variables. For multivariable analyses,logistic regression analyses were performed to identifycharacteristics associated with hepatic steatosis. Allreported P values are based two-sided tests, and aP value of less than 0.05 was considered to indicatestatistical significance.RESULTS: The mean age and body mass index (BMI)of the study participants were 49.1 years and 31.3 kg/m2, respectively. Among them, 65.6% were females,52% had hepatic steatosis, 49.5% had metabolicsyndrome, and 29% had elevated aminotransferases.Based on established cut-offs for diagnostic panels,between 17%-63% of the entire cohort was predictedto have NASH with indeterminate or advanced fibrosis.Participants with hepatic steatosis had significantlyhigher BMI (32.9 ± 5.6 kg/m2 vs 29.6 ± 6.1 kg/m2,P 〈 0.001) and higher prevalence rates of elevationof ALT (42.2% vs 14.6%, P 〈 0.001), elevation ofaspartate aminotransferase (38.7% vs 18.9%, P 〈0.001), and

    Full Text Available To assess the caregiver burden and factors determining the burden in patients receiving ranibizumab therapy for neovascular AMD (nAMD.This is a cross-sectional questionnaire survey of 250 matched patient caregiver dyads across three large ophthalmic treatment centres in United Kingdom. The primary outcome was the subjective caregiver burden measured using caregiver reaction assessment scale (CRA. Objective caregiver burden was determined by the caregiver tasks and level of care provided. The factors that may predict the caregiver burden such as the patient's visual acuity of the better eye and vision related quality of life, demographics, satisfaction and support provided by the healthcare and the health status of the dyads were also collected and assessed in a hierarchical regression model.The mean CRA score was 3.2±0.5, similar to the score reported by caregivers for atrial fibrillation who require regular hospital appointments for monitoring their thromboprophylaxis. Caregiver tasks including accompanying for hospital appointments for eye treatment and patient's visual acuity in the better eye were the biggest contributors to the caregiver burden hierarchical model explaining 18% and 11% of the variance respectively.Ranibizumab therapy for nAMD is associated with significant caregiver burden. Both disease impact and treatment frequency contributed to the overall burden.

    2015-07-01

    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

    This article uses the 2013 Current Population Survey Annual Social and Economic Supplement to estimate the financial burden of medical out-of-pocket costs by comparing medical out-of-pocket expenditures to income. This measure is important for evaluating the magnitude of burden, better understanding who bears it, and establishing a baseline to assess the impact of the Patient Protection and Affordable Care Act. We examine the distribution of burden and the incidence of high burden across all families and by individuals' health insurance status and demographic and socioeconomic characteristics. We look more closely at one group vulnerable to having high burden: those younger than age 65 with incomes between 138% and 200% of the federal poverty line. We find that 18.5% of these individuals have incomes below the threshold of expansion Medicaid eligibility after accounting for non-over-the-counter medical expenses and examine the characteristics associated with being classified below this threshold.

    The use of evidence-based practices (EBPs) is associated with favorable client outcomes, yet perceived burden of using EBPs may affect the adoption and implementation of such practices. Multilevel path analysis was used to examine the associations of transformational leadership with organizational climate, and their associations with perceived burden of using EBPs. Results indicated significant relationships between transformational leadership and empowering and demoralizing climates, and between demoralizing climate and perceived burden of EBPs. We found significant indirect associations of leadership and perceived burden through organizational climate. Findings suggest that further research is needed to examine the extent to which improving leadership and organizational climate may reduce perceived burden and use of EBPs with the ultimate goal of enhancing quality of care.

    Most people would like to change something about their bodies and the way that they look, but for some it becomes an obsession. A healthy skin plays an important role in a person's physical and mental wellbeing, whereas a disfiguring appearance is associated with body image concerns. Skin diseases such as acne, psoriasis and vitiligo produce cosmetic disfigurement and patients suffering these and other visible skin conditions have an increased risk of depression, anxiety, feelings of stigmatization and self-harm ideation. Body image affects our emotions, thoughts, and behaviours in everyday life, but, above all, it influences our relationships. Furthermore, it has the potential to influence our quality of life. Promotion of positive body image is highly recommended, as it is important in improving people's quality of life, physical health, and health-related behaviors. Dermatologists have a key role in identifying body image concerns and offering patients possible treatment options. PMID:27283435

  4. Consolidated Storage Facilities: Camel's Nose or Shared Burden? - 13112

    International Nuclear Information System (INIS)

    The Blue Ribbon Commission (BRC) made a strong argument why the reformulated nuclear waste program should make prompt efforts to develop one or more consolidated storage facilities (CSFs), and recommended the amendment of NWPA Section 145(b) 2 (linking 'monitored retrievable storage' to repository development) as an essential means to that end. However, other than recommending that the siting of CSFs should be 'consent-based' and that spent nuclear fuel (SNF) at stranded sites should be first-in-line for removal, the Commission made few recommendations regarding how CSF development should proceed. Working with three other key Senators, Jeff Bingaman attempted in the 112. Congress to craft legislation (S. 3469) to put the BRC recommendations into legislative language. The key reason why the Nuclear Waste Administration Act of 2012 did not proceed was the inability of the four senators to agree on whether and how to amend NWPA Section 145(b). A brief review of efforts to site consolidated storage since the Nuclear Waste Policy Amendments Act of 1987 suggests a strong and consistent motivation to shift the burden to someone (anyone) else. This paper argues that modification of NWPA Section 145(b) should be accompanied by guidelines for regional development and operation of CSFs. After review of the BRC recommendations regarding CSFs, and the 'camel's nose' prospects if implementation is not accompanied by further guidelines, the paper outlines a proposal for implementation of CSFs on a regional basis, including priorities for removal from reactor sites and subsequently from CSFs to repositories. Rather than allowing repository siting to be prejudiced by the location of a single remote CSF, the regional approach limits transport for off-site acceptance and storage, increases the efficiency of removal operations, provides a useful basis for compensation to states and communities that accept CSFs, and gives states with shared circumstances a shared stake in storage and

    Full Text Available BACKGROUND: We conducted a surveillance study to determine the leading causes of bloodstream infection in febrile patients seeking treatment at three district hospitals in Pemba Island, Zanzibar, Tanzania, an area with low malaria transmission. METHODS: All patients above two months of age presenting to hospital with fever were screened, and blood was collected for microbiologic culture and malaria testing. Bacterial sepsis and malaria crude incidence rates were calculated for a one-year period and were adjusted for study participation and diagnostic sensitivity of blood culture. RESULTS: Blood culture was performed on 2,209 patients. Among them, 166 (8% samples yielded bacterial growth; 87 (4% were considered as likely contaminants; and 79 (4% as pathogenic bacteria. The most frequent pathogenic bacteria isolated were Salmonella Typhi (n = 46; 58%, followed by Streptococcus pneumoniae (n = 12; 15%. The crude bacteremia rate was 6/100,000 but when adjusted for potentially missed cases the rate may be as high as 163/100,000. Crude and adjusted rates for S. Typhi infections and malaria were 4 and 110/100,000 and 4 and 47/100,000, respectively. Twenty three (51%, 22 (49% and 22 (49% of the S. Typhi isolates were found to be resistant toward ampicillin, chloramphenicol and cotrimoxazole, respectively. Multidrug resistance (MDR against the three antimicrobials was detected in 42% of the isolates. CONCLUSIONS: In the presence of very low malaria incidence we found high rates of S. Typhi and S. pneumoniae infections on Pemba Island, Zanzibar. Preventive measures such as vaccination could reduce the febrile disease burden.

    Full Text Available Abstract Background Studies on the association between prostate cancer and cadmium exposure have yielded conflicting results. This study explored cadmium burden on the risk and phenotype of prostate cancer in men with no evident environmental exposure. Methods Hospital-based 261 prostate cancer cases and 267 controls with benign diseases were recruited from four hospitals in Taiwan. Demographic, dietary and lifestyle data were collected by standardized questionnaires. Blood cadmium (BCd and creatinine-adjusted urine cadmium (CAUCd levels were measured for each participant. Statistical analyses measured the prostate cancer risk associated with BCd and CAUCd separately, controlling for age, smoking and institution. BCd and CAUCd levels within cases were compared in relation to the disease stage and the Gleason score. Results High family income, low beef intake, low dairy product consumption and positive family history were independently associated with the prostate carcinogenesis. There was no difference in BCd levels between cases and controls (median, 0.88 versus 0.87 μg/l, p = 0.45. Cases had lower CAUCd levels than controls (median, 0.94 versus 1.40 μg/g creatinine, p = 0.001. However, cases with higher BCd and CAUCd levels tended to be at more advanced stages and to have higher Gleason scores. The prostate cancer cases with Gleason scores of ≥ 8 had an odds ratio of 2.89 (95% confidence interval 1.25-6.70, compared with patients with scores of 2-6. Conclusion Higher CAUCd and BCd levels may be associated with advanced cancer phenotypes, but there was only a tenuous association between cadmium and prostate cancer.

    Background and Purpose Cerebral microinfarcts (CMI) are important contributors to vascular cognitive impairment. MRI diffusion-weighted imaging (DWI) hyperintensities have been suggested to represent acute CMI. We aim to describe a mathematical method for estimating total number of CMI based on the presence of incidental DWI lesions. Methods We reviewed MRI scans of subjects with cognitive decline, cognitively normal subjects and previously reported subjects with past intracerebral hemorrhage (ICH). Based on temporal and spatial characteristics of DWI lesions we estimated the annual rate of CMI needed to explain the observed rate of DWI lesion detection in each group. To confirm our estimates we performed extensive sampling for CMI in the brain of a deceased subject with past lobar ICH who found to have a DWI lesion during life. Results Clinically silent DWI lesions were present in 13 of 343 (3.8%) cognitively impaired, and 10 of 199 (5%) cognitively intact normal non-ICH patients, both lower than the incidence in the past ICH patients (23 of 178, 12.9%, p<0.0006). The predicted annual incidence of CMI ranges from 16 to 1566 for non-ICH and 50 to 5041 for ICH individuals. Histologic sampling revealed a total of 60 lesions in 32 sections. Based on previously reported methods, this density of CMI yields an estimated total brain burden MLE of 9321 CMIs (95% CI 7255–11990). Conclusions Detecting even a single DWI lesion suggests an annual incidence of hundreds of new CMI. The cumulative effects of these lesions may directly contribute to small-vessel-related vascular cognitive impairment PMID:26159796

  8. Conservation efforts may increase malaria burden in the Brazilian Amazon.

    Directory of Open Access Journals (Sweden)

    Denis Valle

    Full Text Available BACKGROUND: Large-scale forest conservation projects are underway in the Brazilian Amazon but little is known regarding their public health impact. Current literature emphasizes how land clearing increases malaria incidence, leading to the conclusion that forest conservation decreases malaria burden. Yet, there is also evidence that proximity to forest fringes increases malaria incidence, which implies the opposite relationship between forest conservation and malaria. We compare the effect of these environmental factors on malaria and explore its implications. METHODS AND FINDINGS: Using a large malaria dataset (~1,300,000 positive malaria tests collected over ~4.5 million km(2, satellite imagery, permutation tests, and hierarchical Bayesian regressions, we show that greater forest cover (as a proxy for proximity to forest fringes tends to be associated with higher malaria incidence, and that forest cover effect was 25 times greater than the land clearing effect, the often cited culprit of malaria in the region. These findings have important implications for land use/land cover (LULC policies in the region. We find that cities close to protected areas (PA's tend to have higher malaria incidence than cities far from PA's. Using future LULC scenarios, we show that avoiding 10% of deforestation through better governance might result in an average 2-fold increase in malaria incidence by 2050 in urban health posts. CONCLUSIONS: Our results suggest that cost analysis of reduced carbon emissions from conservation efforts in the region should account for increased malaria morbidity, and that conservation initiatives should consider adopting malaria mitigation strategies. Coordinated actions from disparate science fields, government ministries, and global initiatives (e.g., Reduced Emissions from Deforestation and Degradation; Millenium Development Goals; Roll Back Malaria; and Global Fund to Fight AIDS, Tuberculosis and Malaria, will be required to

    Ajay Mahal

    Full Text Available We assessed the burden of cancer on households' out-of-pocket health spending, non-medical consumption, workforce participation, and debt and asset sales using data from a nationally representative health and morbidity survey in India for 2004 of nearly 74 thousand households. Propensity scores were used to match households containing a member diagnosed with cancer (i.e. cancer-affected households to households with similar socioeconomic and demographic characteristics (controls. Our estimates are based on data from 1,645 households chosen through matching. Cancer-affected households experienced higher levels of outpatient visits and hospital admissions and increased out-of-pocket health expenditures per member, relative to controls. Cancer-affected households spent between Indian Rupees (INR 66 and INR 85 more per member on healthcare over a 15-day reference period, than controls and additional expenditures (per member incurred on inpatient care by cancer-affected households annually is equivalent to 36% to 44% of annual household expenditures of matched controls. Members without cancer in cancer-affected households used less health-care and spent less on healthcare. Overall, adult workforce participation rates were lower by between 2.4 and 3.2 percentage points compared to controls; whereas workforce participation rates among adult members without cancer were higher than in control households. Cancer-affected households also had significantly higher rates of borrowing and asset sales for financing outpatient care that were 3.3% to 4.0% higher compared to control households; and even higher for inpatient care.

    Full Text Available Introduction: In this review, the International Agency for Research on Cancer′s cancer epidemiology databases were used to examine prostate cancer (PCa age-standardized incidence rates (ASIR in selected Asian nations, including Cancer Incidence in Five Continents (CI5 and GLOBOCAN databases, in an effort to determine whether ASIRs are rising in regions of the world with historically low risk of PCa development. Materials and Methods: Asian nations with adequate data quality were considered for this review. PCa ASIR estimates from CI5 and GLOBOCAN 2008 public use databases were examined in the four eligible countries: China, Japan, Korea and Singapore. Time trends in PCa ASIRs were examined using CI5 Volumes I-IX. Results: While PCa ASIRs remain much lower in the Asian nations examined than in North America, there is a clear trend of increasing PCa ASIRs in the four countries examined. Conclusion: Efforts to systematically collect cancer incidence data in Asian nations must be expanded. Current CI5 data indicate a rise in PCa ASIR in several populous Asian countries. If these rates continue to rise, it is uncertain whether there will be sufficient resources in place, in terms of trained personnel and infrastructure for medical treatment and continuum of care, to handle the increase in PCa patient volume. The recommendation by some experts to initiate PSA screening in Asian nations could compound a resource shortfall. Obtaining accurate estimates of PCa incidence in these countries is critically important for preparing for a potential shift in the public health burden posed by this disease.

  11. Estimating the non-monetary burden of neurocysticercosis in Mexico.

    Directory of Open Access Journals (Sweden)

    Rachana Bhattarai

    Full Text Available BACKGROUND: Neurocysticercosis (NCC is a major public health problem in many developing countries where health education, sanitation, and meat inspection infrastructure are insufficient. The condition occurs when humans ingest eggs of the pork tapeworm Taenia solium, which then develop into larvae in the central nervous system. Although NCC is endemic in many areas of the world and is associated with considerable socio-economic losses, the burden of NCC remains largely unknown. This study provides the first estimate of disability adjusted life years (DALYs associated with NCC in Mexico. METHODS: DALYs lost for symptomatic cases of NCC in Mexico were estimated by incorporating morbidity and mortality due to NCC-associated epilepsy, and morbidity due to NCC-associated severe chronic headaches. Latin hypercube sampling methods were employed to sample the distributions of uncertain parameters and to estimate 95% credible regions (95% CRs. FINDINGS: In Mexico, 144,433 and 98,520 individuals are estimated to suffer from NCC-associated epilepsy and NCC-associated severe chronic headaches, respectively. A total of 25,341 (95% CR: 12,569-46,640 DALYs were estimated to be lost due to these clinical manifestations, with 0.25 (95% CR: 0.12-0.46 DALY lost per 1,000 person-years of which 90% was due to NCC-associated epilepsy. CONCLUSION: This is the first estimate of DALYs associated with NCC in Mexico. However, this value is likely to be underestimated since only the clinical manifestations of epilepsy and severe chronic headaches were included. In addition, due to limited country specific data, some parameters used in the analysis were based on systematic reviews of the literature or primary research from other geographic locations. Even with these limitations, our estimates suggest that healthy years of life are being lost due to NCC in Mexico.

    Full Text Available Abstract Methylmercury (MeHg exposure can cause adverse health effects in children and adults and is predominantly from seafood consumption in the United States (U.S.. Here we examine evidence for differences in MeHg uptake and metabolism in U.S. individuals who consume three or more fish meals per week. We hypothesized based on prior research that some individuals have enhanced capacity to demethylate ingested MeHg and this will be reflected by a greater than typically observed δ202Hg offset in their hair relative to consumed fish (∼2 ‰. We used self-reported seafood intake data to identify individuals with hair Hg concentrations that agree extremely well with reported ingestion and those that do not. Approximately one-third of individuals in our survey population had hair Hg levels below the lower bound of probabilistic exposure modeling based on dietary intake data. The Δ199Hg values measured in the hair of a subset of individuals with the highest and lowest discrepancies between modeled and measured exposures are consistent with self-reported fish intake, validating the reliability of their dietary recall information. The δ202Hg offset between fish and human hair is similar for low- and high-discrepancy individuals, suggesting enhanced in vivo demethylation does not explain some individuals with hair Hg levels equivalent to non-fish consumers (0.10 ug/g. Using the probabilistic exposure model, we find dietary MeHg absorption efficiencies required to explain hair Hg levels in these high-discrepancy individuals are on average lower than 14% (range: 1%–72%. Exposure modeling for MeHg typically assumes a range of 91–97% and our results emphasize much greater inter-individual variability in this value.

    In the mid-1940s, the United States began producing atomic weapon components at the Los Alamos National Laboratory (LANL). In an attempt to better understand historical exposure to nearby residents, this study evaluates plutonium activity in human tissue relative to residential location and length of time at residence. Data on plutonium activity in the lung, vertebrae, and liver of nearby residents were obtained during autopsies as a part of the Los Alamos Tissue Program. Participant residential histories and the distance from each residence to the primary plutonium processing buildings at LANL were evaluated in the analysis. Summary statistics, including Student t-tests and simple regressions, were calculated. Because the biological half-life of plutonium can vary significantly by organ, data were analyzed separately by tissue type (lung, liver, vertebrae). The ratios of plutonium activity (vertebrae:liver; liver:lung) were also analyzed in order to evaluate the importance of timing of exposure. Tissue data were available for 236 participants who lived in a total of 809 locations, of which 677 were verified postal addresses. Residents of Los Alamos were found to have higher plutonium activities in the lung than non-residents. Further, those who moved to Los Alamos before 1955 had higher lung activities than those who moved there later. These trends were not observed with the liver, vertebrae, or vertebrae:liver and liver:lung ratio data, however, and should be interpreted with caution. Although there are many limitations to this study, including the amount of available data and the analytical methods used to analyze the tissue, the overall results indicate that residence (defined as the year that the individual moved to Los Alamos) may have had a strong correlation to plutonium activity in human tissue. This study is the first to present the results of Los Alamos Autopsy Program in relation to residential status and location in Los Alamos.

    Hongmei Yu

    Full Text Available To assess the direct and indirect effects of patient or caregiver factors on caregiver burden of caring for community-residing people with mild Alzheimer's disease (AD.We conducted a cross-sectional study of patients diagnosed with AD from two hospitals and three communities in Taiyuan, China and their caregivers. For this survey, 200 patients with mild AD and their caregivers were selected. Caregivers were asked to provide sociodemographic information including age, gender, relationship with the patient, level of education, and number of contact hours per week with the patient. Caregiver burden was assessed using the Caregivers Burden Inventory. The caregivers also completed other measures including the Positive Aspects of Caregiving, the Family Adaptation, Partnership, Growth, Affection, and Resolve, and the Social Support Rating Scale. The patients with AD completed the Montreal Cognitive Assessment; their caregivers completed the Activities of Daily Living Scale and a questionnaire about the patients' Behavioral and Psychological symptoms of Dementia. The main outcome in this study was caregiver burden. The care receivers' level of cognitive function, physical function, and behavioral problems were treated as original stress; the primary appraisal variable was measured as the number of hours of caregiving in the previous week reported by the caregiver. Mediator variables included perceived social support, family function, and caregiving experience. Path analysis was used to build the interrelationship among caregiver burden and patient or caregiver factors.A lower level of cognitive function in patients (r = -0.28, p<0.001 and longer hours of caregiving (r = 0.17, p = 0.019 were related to increased caregiver burden. Greater social support (r = -0.23, p<0.001, family function (r = -0.17, p = 0.015 and caregiving experience (r = -0.16, p = 0.012 were related to decreased caregiver burden.

    Full Text Available Family members of patients with schizophrenia have enormous roles in the care of their patients, which could negatively impact their well being. Development of interventions targeted at alleviating the burden of informal care giving is hinged on the recognition of the factors associated with the various dimensions of burden. This study determined the correlates of caregiver burden among family members of patients with schizophrenia in Lagos, Nigeria. The study instruments included the Zarit burden interview (ZBI and the positive and negative syndrome scale for schizophrenia (PANSS. Exploratory factor analysis of the ZBI produced a five-factor structure with “financial/physical strain”, “time/dependence strain”, “emotional strain”, “uncertainty”, and “self-criticism” domains. On multiple regression analyses, total PANSS scores, poor social support, and lower educational levels of caregivers were predictive of higher burden scores on the “financial/physical strain”, “time/dependence”, and “emotional strain” domains. Longer duration of illness, shorter patient-caregiver contact time, and being a female caregiver were predictive of higher burden scores on the “uncertainty”, “self-criticism”, and “emotional strain” domains, respectively. There is need for interventions to alleviate the burden on caregivers of patients with schizophrenia in Nigeria. These strategies must include comprehensive social support and improve access to services for patients and their caregivers.

    Invasive meningococcal disease remains a substantial global public health burden despite being vaccine-preventable worldwide. More than one million cases are reported annually, with average fatality rates ranging from 10% to 40% depending on clinical presentation and geographic location. Survivors may suffer debilitating sequelae that reduce the quality of life for the patient and family members responsible for their care. Major financial burdens are associated with acute treatment and follow-up care, and outbreak management often places extensive financial strains on public health resources. Although the clinical and financial aspects of meningococcal disease burden are straightforward to quantify, other burdens such as lifelong cognitive deficits, psychological stress, adaptive measures for reintegration into society, familial impact, and legal costs are systematically overlooked. These and other facets of disease burden are therefore not systematically considered in cost-effectiveness analyses that public health authorities take into consideration when making decisions regarding vaccination programs. Changing the approach for measuring meningococcal disease burden is necessary to accurately understand the societal consequences of this devastating illness. In this article, the conventional and under-recognized burdens of meningococcal disease are presented and discussed. PMID:27449145

  6. Zooplankton body composition

    2013-01-01

    I compiled literature on zooplankton body composition, from protozoans to gelatinous plankton, and report allometric relations and average body composition. Zooplankton segregate into gelatinous and non-gelatinous forms, with few intermediate taxa (chaetognaths, polychaetes, and pteropods). In most...... groups body composition is size independent. Exceptions are protozoans, chaetognaths, and pteropods, where larger individuals become increasingly watery. I speculate about the dichotomy in body composition and argue that differences in feeding mechanisms and predator avoidance strategies favor either a...

    childhood communicable diseases, including unimproved water and sanitation and childhood micronutrient deficiencies, fell in rank between 1990 and 2010, with unimproved water we and sanitation accounting for 0·9% (0·4–1·6) of global DALYs in 2010. However, in most of sub-Saharan Africa childhood underweight, HAP, and non-exclusive and discontinued breastfeeding were the leading risks in 2010, while HAP was the leading risk in south Asia. The leading risk factor in Eastern Europe, most of Latin America, and southern sub-Saharan Africa in 2010 was alcohol use; in most of Asia, North Africa and Middle East, and central Europe it was high blood pressure. Despite declines, tobacco smoking including second-hand smoke remained the leading risk in high-income north America and western Europe. High body-mass index has increased globally and it is the leading risk in Australasia and southern Latin America, and also ranks high in other high-income regions, North Africa and Middle East, and Oceania. Interpretation Worldwide, the contribution of different risk factors to disease burden has changed substantially, with a shift away from risks for communicable diseases in children towards those for non-communicable diseases in adults. These changes are related to the ageing population, decreased mortality among children younger than 5 years, changes in cause-of-death composition, and changes in risk factor exposures. New evidence has led to changes in the magnitude of key risks including unimproved water and sanitation, vitamin A and zinc deficiencies, and ambient particulate matter pollution. The extent to which the epidemiological shift has occurred and what the leading risks currently are varies greatly across regions. In much of sub-Saharan Africa, the leading risks are still those associated with poverty and those that affect children. Funding Bill & Melinda Gates Foundation. PMID:23245609

  8. CFD modeling of multiphase reacting flow in blast furnace shaft with layered burden

    International Nuclear Information System (INIS)

    The ironmaking blast furnace is a counter-current chemical reactor which includes the ascending gas flow and the counter-current descending porous bed (burden). A Computational Fluid Dynamics (CFD) model has been developed to simulate the multiphase reacting flow in blast furnace shaft. The gas flow dynamics, burden movement, chemical reactions, heat and mass transfer between the gas phase and burden phase are included in the CFD model. The blast furnace burden consists of alternative layers of iron ore and coke. A novel methodology is proposed to efficiently model the effects of alternative burden layer structure on gas flow, heat transfer, mass transfer and chemical reactions. Different reactions and heat transfer characteristics are applied for difference types of layer. In addition, the layered CFD model accurately predicts the Cohesive Zone (CZ) shape where the melting of solid burden taking place. The shape and location of the CZ are determined by an iterative method based on the ore temperature distribution. The theoretical formation and the methodology of the CFD model are presented and the model is applied to simulate industry blast furnaces. The proposed method can be applied to investigate the blast furnace shaft process and other moving bed system with periodic burden structure configuration. - Highlights: •A novel methodology is proposed to efficiently model the blast furnace shaft with layered burden. •The effects of layered burden on flow, heat transfer, and chemical reactions are considered in the model. •The shape and location of the cohesive zone is determined by an iterative method

    Our aim was to investigate the value of salivary concentrations of four major periodontal pathogens and their combination in diagnostics of periodontitis. The Parogene study included 462 dentate subjects (mean age 62.9 ± 9.2 years) with coronary artery disease (CAD) diagnosis who underwent an extensive clinical and radiographic oral examination. Salivary levels of four major periodontal bacteria were measured by quantitative real-time PCR (qPCR). Median salivary concentrations of Porphyromonas gingivalis, Tannerella forsythia, and Prevotella intermedia, as well as the sum of the concentrations of the four bacteria, were higher in subjects with moderate to severe periodontitis compared to subjects with no to mild periodontitis. Median salivary Aggregatibacter actinomycetemcomitans concentrations did not differ significantly between the subjects with no to mild periodontitis and subjects with moderate to severe periodontitis. In logistic regression analysis adjusted for age, gender, diabetes, and the number of teeth and implants, high salivary concentrations of P. gingivalis, T. forsythia, and P. intermedia were significantly associated with moderate to severe periodontitis. When looking at different clinical and radiographic parameters of periodontitis, high concentrations of P. gingivalis and T. forsythia were significantly associated with the number of 4-5 mm periodontal pockets, ≥6 mm pockets, and alveolar bone loss (ABL). High level of T. forsythia was associated also with bleeding on probing (BOP). The combination of the four bacteria, i.e., the bacterial burden index, was associated with moderate to severe periodontitis with an odds ratio (OR) of 2.40 (95% CI 1.39-4.13). When A. actinomycetemcomitans was excluded from the combination of the bacteria, the OR was improved to 2.61 (95% CI 1.51-4.52). The highest OR 3.59 (95% CI 1.94-6.63) was achieved when P. intermedia was further excluded from the combination and only the levels of P. gingivalis and T

    with mental disorders (from 148 studies) was 2.22 (95% CI, 2.12–2.33). Of these, 135 studies revealed that mortality was significantly higher among people with mental disorders than among the comparison population. A total of 67.3% of deaths among people with mental disorders were due to natural causes, 17.5% to unnatural causes, and the remainder to other or unknown causes. The median years of potential life lost was 10 years (n = 24 studies). We estimate that 14.3% of deaths worldwide, or approximately 8 million deaths each year, are attributable to mental disorders. CONCLUSIONS AND RELEVANCE These estimates suggest that mental disorders rank among the most substantial causes of death worldwide. Efforts to quantify and address the global burden of illness need to better consider the role of mental disorders in preventable mortality. PMID:25671328

  12. Estimating the hidden burden of bovine tuberculosis in Great Britain.

    Full Text Available The number of cattle herds placed under movement restrictions in Great Britain (GB due to the suspected presence of bovine tuberculosis (bTB has progressively increased over the past 25 years despite an intensive and costly test-and-slaughter control program. Around 38% of herds that clear movement restrictions experience a recurrent incident (breakdown within 24 months, suggesting that infection may be persisting within herds. Reactivity to tuberculin, the basis of diagnostic testing, is dependent on the time from infection. Thus, testing efficiency varies between outbreaks, depending on weight of transmission and cannot be directly estimated. In this paper, we use Approximate Bayesian Computation (ABC to parameterize two within-herd transmission models within a rigorous inferential framework. Previous within-herd models of bTB have relied on ad-hoc methods of parameterization and used a single model structure (SORI where animals are assumed to become detectable by testing before they become infectious. We study such a conventional within-herd model of bTB and an alternative model, motivated by recent animal challenge studies, where there is no period of epidemiological latency before animals become infectious (SOR. Under both models we estimate that cattle-to-cattle transmission rates are non-linearly density dependent. The basic reproductive ratio for our conventional within-herd model, estimated for scenarios with no statutory controls, increases from 1.5 (0.26-4.9; 95% CI in a herd of 30 cattle up to 4.9 (0.99-14.0 in a herd of 400. Under this model we estimate that 50% (33-67 of recurrent breakdowns in Britain can be attributed to infection missed by tuberculin testing. However this figure falls to 24% (11-42 of recurrent breakdowns under our alternative model. Under both models the estimated extrinsic force of infection increases with the burden of missed infection. Hence, improved herd-level testing is unlikely to reduce recurrence

    Full Text Available Background: Some infectious agents have been shown to be human carcinogens. The current study focused on estimation of cancer burden attributable to infection in different regions of Asia. Methods: By systematically reviewing previous studies of the infection prevalence data of 13 countries in Asia and relative risks of specific cancers, we calculated the population attributable fraction of carcinogenic infections. Using data from GLOBOCAN 2012, the overall country-specific and gender-specific number of new cancer cases and deaths resulting from infection were estimated. Results: Across 13 principal Asian countries, the average prevalence and range was 6.6% (0.5% in Japanese women to 15.0% in Vietnamese men for hepatitis B virus (HBV, 2.6% (0.3% in Iran to 5.1% in Saudi Arabia for hepatitis C virus (HCV, 7.9% (2.8% in Pakistan to 17.7% in China for human papillomavirus (HPV, and 61.8% (12.8% in Indonesia to 91.7% in Bangladesh for Helicobacter pylori (HP. The estimated total number of cancer cases and deaths caused by infection in these 13 countries were 1 212 026 (19.6% of all new cancer cases and 908 549 (22.0% of all deaths from cancer. The fractions of cancer incidence attributable to infection were 19.7% and 19.5% in men and women, respectively. The percentages of cancer deaths attributable to infection were 21.9% and 22.1% in men and women, respectively. Among the main infectious agents, HP was responsible for 31.5% of infection-related cancer cases and 32.8% of infection-related cancer deaths, followed by HBV (28.6% of new cases and 23.8% of deaths, HPV (22.0% of new cases and 27.3% of deaths, and HCV (12.2% of new cases and 10.6% of deaths. Conclusions: Approximately one quarter of all cancer cases and deaths were infection-associated in Asia, which could be effectively prevented if appropriate long-term controls of infectious agents were applied.

    Full Text Available It's currently well known that smoking and increasing age constitute the most important risk factors for chronic obstructive pulmonary disease (COPD. However, little is known about COPD among nonsmokers. The present study aimed to investigate prevalence, risk factors and the profiles of COPD among nonsmokers based on the Tunisian Burden of Obstructive Lung Disease (BOLD study.807 adults aged 40 years+ were randomly selected from the general population. We collected information about history of respiratory disease, risk factors for COPD and quality of life. Post-bronchodilator spirometry was performed for assessment of COPD. COPD diagnostic was based on the post-bronchodilator FEV1/FVC ratio, according to the Global Initiative for Obstructive Lung Disease (GOLD guidelines. The lower limit of normal (LLN was determined as an alternative threshold for the FEV1/FVC ratio.Among 485 nonsmokers, 4.7% met the criteria for GOLD grade I and higher COPD. These proportions were similar even when the LLN was used as a threshold. None of the nonsmokers with COPD reported a previous doctor diagnosis of COPD compared to 7.1% of smokers. Nonsmokers accounted for 45.1% of the subjects fulfilling the GOLD spirometric criteria of COPD. Nonsmokers were predominately men and reported more asthma problems than obstructed smokers. Among nonsmokers significantly more symptoms and higher co-morbidity were found among those with COPD. Increasing age, male gender, occupational exposure, lower body mass index and a previous diagnosis of asthma are associated with increased risk for COPD in nonsmokers. This study confirms previous evidence that nonsmokers comprise a substantial proportion of individuals with COPD. Nonsmokers with COPD have a specific profile and should, thus, receive far greater attention to prevent and treat chronic airway obstruction.

    Full Text Available Blood lead levels (BLLs is considered as a good indicator of current body burden of the toxic metal. Assessment of BLLs of white Fulani cattle(Bos primigenius indicusand red Sokoto goats (Capra aegagrus hircus grazed freely on open pastures in Zaria was carried out by Atomic Absorption Spectrophotometry using Shimadzu Atomic Absorption Spectrophotometer (model AA-6800, Japan after wet digestion to evaluate the potential effects of the metal on the animals, the toxicological implication of consuming this major source of animal protein by humans and most importantly as an indirect measure of the lead pollution status of Zaria ecological geochemical environment. The blood lead levels of Bos primigenius indicus ranged from a minimum of 0.62 mg/l to a maximum of 2.28 mg/l with a mean value of 1.36±0.48 mg/l. On the other hand, blood lead levels of Capra aegagrus hircus ranged between 0.26 mg/l and 1.56 mg/l with a mean value of 0.89±0.43mg/l. The BLLs of both cows and goats were found to exceed the allowable limit for the elements in blood of food animals indicating that cows and goats grazed freely on open pastures in Zaria metropolis are not safe for human consumption. Routine monitoring of the heavy metal in plant and animal products is therefore recommended to safeguard human health. Most importantly, the study indicates the presence of elevated levels of environmental lead in Zaria ecological geochemical environment.

    Decades after Roe, debate over abortion remains as contentious as ever. States continue to pass regulations burdening the abortion right, but lack clear guidance on how to evaluate such regulations using the undue burden test. This Article chronicles Supreme Court jurisprudence on abortion and examines how the current circuit split surrounding FDA-protocol legislation fits within the larger framework. Finally, this Article applies the proper version of the undue burden test to FDA-protocol legislation, which resolves the circuit split and provides lower courts with a clear means of analyzing abortion issues moving forward.

    Full Text Available Background & objectives: During 2006, chikungunya emerged as a major ever known epidemic in India. Disability adjusted life years (DALY is an appropriate summary measure of population health to express epidemiological burden of diseases. We estimated the burden due to suspected chikungunya using DALYs for the first time and compared between the states and also with the burden due to other vector-borne diseases in India. The economic burden was also assessed in terms of productivity loss.Methods: Data on the reported cases of fever/suspected cases of chikungunya from different states during 2006 in India were used. Years lived with disability (YLD were calculated for non-fatal cases to estimate DALY. Since the disability weight for chikungunya is not available, the weights available for rheumatic arthritis, comparable to the disease outcome of chikungunya were used for the estimation. The burden was estimated for both acute and chronic cases. It is considered that about 11.5% of cases were reported to have extended morbidity with persisting arthralgia. For acute disease, the average duration of illness was considered to be nine days and for chronic cases it was six months on an average. The productivity loss due to income foregone by the working class was calculated using minimum official wage.Results: National burden of chikungunya was estimated to be 25,588 DALYs lost during 2006 epidemic, with an overall burden of 45.26 DALYs per million. It varied from 0.01 to 265.62 per million in different states. Karnataka alone contributed as high as 55% of the national burden. Persistent arthralgia was found to impose heavy burden, accounting for 69% of the total DALYs. The productivity loss in terms of income foregone was estimated to be a minimum of Rs. 391 million. Interpretation & conclusion: The chikungunya epidemic in the year 2006 imposed heavy epidemiological burden and productivity loss to the community. The burden of chikungunya in terms of

    Full Text Available BACKGROUND: Body weight and body composition are relevant to the outcomes of cancer and antineoplastic therapy. However, their role in Phase I clinical trial patients is unknown. METHODS: We reviewed symptom burden, body composition, and survival in 104 patients with advanced cancer referred to a Phase I oncology service. Symptom burden was analyzed using the MD Anderson Symptom Assessment Inventory(MDASI; body composition was evaluated utilizing computerized tomography(CT images. A body mass index (BMI≥25 kg/m² was considered overweight. Sarcopenia, severe muscle depletion, was assessed using CT-based criteria. RESULTS: Most patients were overweight (n = 65, 63%; 53 patients were sarcopenic (51%, including 79% of patients with a BMI<25 kg/m² and 34% of those with BMI≥25 kg/m². Sarcopenic patients were older and less frequently African-American. Symptom burden did not differ among patients classified according to BMI and presence of sarcopenia. Median (95% confidence interval survival (days varied according to body composition: 215 (71-358 (BMI<25 kg/m²; sarcopenic, 271 (99-443 (BMI<25 kg/m²; non-sarcopenic, 484 (286-681 (BMI≥25 kg/m²; sarcopenic; 501 d (309-693 (BMI≥25 kg/m²; non-sarcopenic. Higher muscle index and gastrointestinal cancer diagnosis predicted longer survival in multivariate analysis after controlling for age, gender, performance status, and fat index. CONCLUSIONS: Patients referred to a Phase I clinic had a high frequency of sarcopenia and a BMI≥25 kg/m², independent of symptom burden. Body composition variables were predictive of clinically relevant survival differences, which is potentially important in developing Phase I studies.

    This review was undertaken to consolidate information on the epidemiology and burden of influenza B, as well as the circulation patterns of influenza B lineage in 9 European countries. Following a comprehensive search of peer-reviewed and gray literature sources, we found that published data on influenza B epidemiology and burden are scarce. Surveillance data show frequent co-circulation of both influenza B lineages during influenza seasons, but little is known about its impact, especially in adults and the clinical burden of influenza B remains unknown. Mismatch between the circulating influenza B lineage and vaccine recommendations has been seen in at least one influenza season in every country. Such observations could impact the effectiveness of seasonal influenza vaccination programs using trivalent vaccines, which contain only one influenza B lineage (B/Yamagata or B/Victoria) and highlight the need for local studies to better understand the epidemiology and burden of influenza B in these countries.

    Full Text Available Background: Caring for a patient with Alzheimer’s disease (AD is associated with poor quality of life and deteriorating health for the caregiver. Methods: This comprehensive review was performed to investigate the current literature on caregiver burden, factors affecting caregiver burden and the effectiveness of different types of intervention. Results: Successful psychoeducational interventions for caregivers have included provision of information about AD, care planning, advice about patient management and the importance of self-care, skills training to aid patient management, stress management training, and problem-solving and decision-making guidance. Conclusion: Interventions that are individually tailored to the caregiver are particularly effective at reducing caregiver burden and should be further investigated. The use of effective pharmacological treatment for the improvement and/or stabilisation of AD symptoms in the patient is also likely to improve caregiver burden.

  11. The measurement of thorium lung burden and its preventive function for pneumoconiosis

    International Nuclear Information System (INIS)

    Objective: To discuss the measurement of thorium lung burden and its preventive function for pneumoconiosis. Methods: Exhaled thoron activity was measured by a negative high voltage electrostatic collection and measurement system. Pneumoconiosis were diagnosed by double-blinded method. Results: 50 out of 275 miners suffered from 0+ pneumoconiosis. The result showed that if one's thorium lung burden reached 756 mg, the pneumoconiosis of stage 0+ would be induced. Meanwhile the result of 7 year-follow-up study on a miner suffered from pneumoconiosis stage I indicated that 44% of the residual lung burden was clearing with a half-time of 112 days. However, the half-time of the second phase was ∼ 7000 years. Conclusion: The measurement of thorium lung burden could help the prevention from pneumoconiosis. (authors)

    Skin conditions often have a severe impact on the physical and psychosocial domains of patients' quality of life, but the relationship between these domains has been studied little. This study estimated the fraction of psychosocial burden that may be attributable to symptoms, using the Skindex-17 quality of life questionnaire (symptoms and psychosocial scales) in 2,487 outpatients. The excess proportion of psychosocial burden for each skin condition was computed. Overall, 79.8% of the psychosocial burden of patients with severe symptoms may be attributable to the symptoms. For patients with mild symptoms this figure is 49.7%. A great heterogeneity was observed, from -0.9% for patients with scars, up to more than 90% for conditions such as lichen planus and psoriasis. While these results will have to be confirmed in longitudinal studies, they seem to indicate that, by targeting specific symptoms, a substantial portion of the psychosocial burden of skin diseases could be spared.

    Full Text Available The main thrust of the paper - an attempt to assess how much the sanctions combined with the drop in oil prices hit the consumers. This paper provides an overview of the sanctions imposed by European Union, the United States and other countries (ban largest organizations in Russia to attract foreign capital of the European Union and the United States. The burden of economic sanctions against Russia for the average consumer is shown on the change in prices for food products, electronic products, analyzed Russian car market, the dynamics of small and medium-sized businesses in Russia. The results of import substitution - the balances of trade of consumer goods in Q1 2015 compared to Q1 2014. Dynamics of demand for electronic goods in the paper discusses the example of the effect of price changes in the popular Russian companies (Apple, Sony, etc. to sales. Rising prices for electronic goods has led Apple to a Giffen’s paradox in late 2014, the higher the price - the more sales. Despite the rapid rise in prices for the company's products (price of products apple Nov. 25 rose by 25% on December 22 for another 35%, sales growth was 80%. This is due to the fact that Russian consumers feared further rise in price of goods and the goods were afraid to lose, which has become for many of them a necessity. Car loans in Q1 2015 compared to Q1 2014 decreased by 4 times, car sales fell by 2 times, import cars from abroad fell almost 2-fold. Especially hard hit small businesses. If in 2013 in Russia was opened 490.7 thous. legal entities, and closed 419 thousand. Then for 11 months in 2014 opened 417.5 ths. legal entities and closed down 483.6 thousand. This means that if in 2013 opening of 70 thousand legal persons more, in 2014 almost 70 thousand legal persons shut more than open. Statistics show that the number of people wishing to sell his business in 2014 increased significantly. In Moscow, for example, in 2014, it was filed with the 14.5 times the

    Full Text Available Abstract Background The health authorities of Niger have implemented several malaria prevention and control programmes in recent years. These interventions broadly follow WHO guidelines and international recommendations and are based on interventions that have proved successful in other parts of Africa. Most performance indicators are satisfactory but, paradoxically, despite the mobilization of considerable human and financial resources, the malaria-fighting programme in Niger seems to have stalled, as it has not yet yielded the expected significant decrease in malaria burden. Indeed, the number of malaria cases reported by the National Health Information System has actually increased by a factor of five over the last decade, from about 600,000 in 2000 to about 3,000,000 in 2010. One of the weaknesses of the national reporting system is that the recording of malaria cases is still based on a presumptive diagnosis approach, which overestimates malaria incidence. Methods An extensive nationwide survey was carried out to determine by microscopy and RDT testing, the proportion of febrile patients consulting at health facilities for suspected malaria actually suffering from the disease, as a means of assessing the magnitude of this problem and obtaining a better estimate of malaria morbidity in Niger. Results In total, 12,576 febrile patients were included in this study; 57% of the slides analysed were positive for the malaria parasite during the rainy season, when transmission rates are high, and 9% of the slides analysed were positive during the dry season, when transmission rates are lower. The replacement of microscopy methods by rapid diagnostic tests resulted in an even lower rate of confirmation, with only 42% of cases testing positive during the rainy season, and 4% during the dry season. Fever alone has a low predictive value, with a low specificity and sensitivity. These data highlight the absolute necessity of confirming all reported

    Editors' Summary Background. The impact that a particular disease has upon a population is known as the “burden of disease.” This burden is estimated by considering how many deaths the disease causes and how much it disables those still living. The relative contributions of different diseases and injuries to the loss of healthy life from death and disability vary greatly among countries. Broadly speaking, in low-income countries (such as many African countries), infectious diseases and undern...

    Illness and death from diseases caused by contaminated food are a constant threat to public health and a significant impediment to socio-economic development worldwide. To measure the global and regional burden of foodborne disease (FBD), the World Health Organization (WHO) established the Foodborne Disease Burden Epidemiology Reference Group (FERG), which here reports their first estimates of the incidence, mortality, and disease burden due to 31 foodborne hazards. We find that the global burden of FBD is comparable to those of the major infectious diseases, HIV/AIDS, malaria and tuberculosis. The most frequent causes of foodborne illness were diarrheal disease agents, particularly norovirus and Campylobacter spp. Diarrheal disease agents, especially non-typhoidal Salmonella enterica, were also responsible for the majority of deaths due to FBD. Other major causes of FBD deaths were Salmonella Typhi, Taenia solium and hepatitis A virus. The global burden of FBD caused by the 31 hazards in 2010 was 33 million Disability Adjusted Life Years (DALYs); children under five years old bore 40% of this burden. The 14 subregions, defined on the basis of child and adult mortality, had considerably different burdens of FBD, with the greatest falling on the subregions in Africa, followed by the subregions in South-East Asia and the Eastern Mediterranean D subregion. Some hazards, such as non-typhoidal S. enterica, were important causes of FBD in all regions of the world, whereas others, such as certain parasitic helminths, were highly localised. Thus, the burden of FBD is borne particularly by children under five years old-although they represent only 9% of the global population-and people living in low-income regions of the world. These estimates are conservative, i.e., underestimates rather than overestimates; further studies are needed to address the data gaps and limitations of the study. Nevertheless, all stakeholders can contribute to improvements in food safety

    Full Text Available Abstract Background Little evidence on the burden of disease has been reported about Guinea. This study was conducted to demonstrate the morbidity burden in Guinea and provide basic evidence for setting health priorities. Methods A retrospective descriptive study was designed to present the morbidity burden of Guinea. Morbidity data were extracted from the National Health Statistics Report of Guinea of 2008. The data are collected based on a pyramid of facilities which includes two national hospitals (teaching hospitals, seven regional hospitals, 26 prefectural hospitals, 8 communal medical centers, 390 health centers, and 628 health posts. Morbidity rates were calculated to measure the burden of non-fatal diseases. The contributions of the 10 leading diseases were presented by sex and age group. Results In 2008, a total of 3,936,599 cases occurred. The morbidity rate for males was higher than for females, 461 versus 332 per 1,000 population. Malaria, respiratory infections, diarrheal diseases, helminthiases, and malnutrition ranked in the first 5 places and accounted for 74% of the total burden, respectively having a rate of 148, 64, 33, 32, and 14 per 1,000 population. The elderly aged 65+ had the highest morbidity rate (611 per 1,000 population followed by working-age population (458 per 1,000 population and children (396 per 1,000 population while the working-age population aged 25-64 contributed the largest part (39% to total cases. The sex- and age-specific spectrum of morbidity burden showed a similar profile except for small variations. Conclusion Guinea has its unique morbidity burden. The ten leading causes of morbidity burden, especially for malaria, respiratory infections, diarrheal diseases, helminthiases, and malnutrition, need to be prioritized in Guinea.
