RESUMO

AbstractPremature discontinuation from behavioral health treatment is a major problem reducing effectiveness of care in military populations. A training was developed and delivered to 622 behavioral health providers across 15 sites within the Army behavioral healthcare system. The training taught two techniques to foster treatment engagement: (1) Progress Informed Treatment, consisting of reviewing symptom assessments and outcome measures, and (2) assessment and discussion of the treatment alliance via a paper survey given near the end of each session. Eighty-five percent of providers indicated the training was useful and 89% of providers incorporated a technique into their practice. Dropout before the fourth session was significantly reduced in the six months following training, from 72.5% to 67.1% in Service Members (SM; X2(1, N=9127) = 39.58, p < .001). In both the pre and post-training periods, providers working at the Master's level, SM aged 17 or 46 or older, and clients receiving a mood, PTSD, anxiety, adjustment, substance or childhood/adolescent psychiatric diagnosis experienced significantly less dropout, while SM aged 18-21 had significantly more dropout. This training is a feasible and available option to increase treatment engagement and improve treatment outcomes for service members.

RESUMO

Usual sleep duration is a heritable trait correlated with psychiatric morbidity, cardiometabolic disease and mortality, although little is known about the genetic variants influencing this trait. A genome-wide association study (GWAS) of usual sleep duration was conducted using 18 population-based cohorts totaling 47 180 individuals of European ancestry. Genome-wide significant association was identified at two loci. The strongest is located on chromosome 2, in an intergenic region 35- to 80-kb upstream from the thyroid-specific transcription factor PAX8 (lowest P=1.1 × 10(-9)). This finding was replicated in an African-American sample of 4771 individuals (lowest P=9.3 × 10(-4)). The strongest combined association was at rs1823125 (P=1.5 × 10(-10), minor allele frequency 0.26 in the discovery sample, 0.12 in the replication sample), with each copy of the minor allele associated with a sleep duration 3.1 min longer per night. The alleles associated with longer sleep duration were associated in previous GWAS with a more favorable metabolic profile and a lower risk of attention deficit hyperactivity disorder. Understanding the mechanisms underlying these associations may help elucidate biological mechanisms influencing sleep duration and its association with psychiatric, metabolic and cardiovascular disease.

RESUMO

CONTEXT: Endothelial function is abnormal in chronic obstructive pulmonary disease (COPD); whether endothelial dysfunction causes COPD is unknown. OBJECTIVE: Test associations of endothelial biomarkers with FEV1 using instrumental variables. METHODS: Among 26 907 participants with spirometry, ICAM-1, P-selectin, E-selectin and endothelin-1 were measured in subsets. RESULTS: ICAM-1 and P-selectin were inversely associated with FEV1 among European-Americans (-29 mL and -34 mL per standard deviation of log-transformed biomarker, p < 0.001), as was endothelin-1 among African-Americans (-22 mL, p = 0.008). Genetically-estimated ICAM-1 and P-selectin were not significantly associated with FEV1. The instrumental variable for endothelin-1 was non-informative. CONCLUSION: Although ICAM-1, P-selectin and endothelin-1 were inversely associated with FEV1, associations for ICAM-1 and P-selectin do not appear causal.

RESUMO

BACKGROUND: Single nucleotide polymorphisms (SNPs) in thymic stromal lymphopoietin (TSLP) have been associated with IgE (in girls) and asthma (in general). We sought to determine whether TSLP SNPs are associated with asthma in a sex-specific fashion. METHODS: We conducted regular and sex-stratified analyses of association between SNPs in TSLP and asthma in families of children with asthma in Costa Rica. Significant findings were replicated in whites and African-American participants in the Childhood Asthma Management Program, in African-Americans in the Genomic Research on Asthma in the African Diaspora study, in whites and Hispanics in the Children's Health Study, and in whites in the Framingham Heart Study (FHS). MAIN RESULTS: Two SNPs in TSLP (rs1837253 and rs2289276) were significantly associated with a reduced risk of asthma in combined analyses of all cohorts (P values of 2 × 10(-5) and 1 × 10(-5) , respectively). In a sex-stratified analysis, the T allele of rs1837253 was significantly associated with a reduced risk of asthma in males only (P = 3 × 10(-6) ). Alternately, the T allele of rs2289276 was significantly associated with a reduced risk of asthma in females only (P = 2 × 10(-4) ). Findings for rs2289276 were consistent in all cohorts except the FHS. CONCLUSIONS: TSLP variants are associated with asthma in a sex-specific fashion.

RESUMO

OBJECTIVE: The NHLBI Family Heart Study (FHS) genome-wide linkage scan identified a region of chromosome 7q with a logarithm of odds score of 4.9 for body mass index (BMI). DESIGN: We report the results of fine mapping the linkage peak using 1020 single nucleotide polymorphisms (SNPs) to test for association to obesity in families exhibiting linkage to chromosome 7. Association observed in linked families (284 obese cases/381 controls) was examined in an independent set of unrelated FHS participants (172 obese cases/308 controls) to validate the observed association. Two dichotomous obesity phenotypes were studied based on clinical BMI cutoffs and the sex-specific distribution of both BMI and leptin levels. RESULTS: Using a P-value of 0.01 as criteria for association in the linked families, a P-value of 0.05 as criteria for association in the unrelated sample, and requiring consistency in the direction of the effect of the minor allele between the two samples, we identified two coding SNPs in the NYD-SP18 gene with minor alleles increasing the risk of obesity. Adjustment for exercise, smoking and FTO genotype did not influence the result in linked families, but improved the result in the unrelated sample. Carrying a minor allele of the nonsynonymous SNP rs6971091 conferred an odds ratio of at least 2 for obesity defined by both BMI and leptin levels. CONCLUSION: The effect of the NYD-SP18 SNP on obesity was larger than the effect of FTO in FHS families. Publicly available results from genome-wide association studies support the association between NYD-SP18 and BMI. The NYD-SP18 gene is described as testes development related, but little is known about the gene's function or the mechanism by which it may influence risk for obesity.

RESUMO

BACKGROUND: The functional outcome after stroke is improved by more intensive or sustained therapy. When the affected hand has no functional movement, therapy is mainly passive movements. A novel device for repeating controlled passive movements of paralysed fingers has been developed, which will allow therapists to concentrate on more complicated tasks. A powered cam shaft moves the four fingers in a physiological range of movement. METHODS: After refining the training protocol in 2 chronic patients, 8 sub-acute stroke patients were randomised to receive additional therapy with the Finger Trainer for 20 min every work day for four weeks, or the same duration of bimanual group therapy, in addition to their usual rehabilitation. RESULTS: In the chronic patients, there was a sustained reduction in finger and wrist spasticity, but there was no improvement in active movements. In the subacute patients, mean distal Fugl-Meyer score (0-30) increased in the control group from 1.25 to 2.75 (ns) and 0.75 to 6.75 in the treatment group (p < .05). Median Modified Ashworth score increased 0/5 to 2/5 in the control group, but not in the treatment group, 0 to 0. Only one patient, in the treatment group, regained function of the affected hand. No side effects occurred. CONCLUSION: Treatment with the Finger Trainer was well tolerated in sub-acute & chronic stroke patients, whose abnormal muscle tone improved. In sub-acute stroke patients, the Finger Trainer group showed small improvements in active movement and avoided the increase in tone seen in the control group. This series was too small to demonstrate any effect on functional outcome however.

RESUMO

BACKGROUND: Calcified coronary plaque (CCP) is a complex trait influenced by both genes and environment, and plausibly an interaction between the two. Because the familial aggregation of CCP has been demonstrated and smoking is a significant, independent predictor of CCP, we assessed the evidence for genotype-by-smoking interaction and conducted linkage analysis of quantitative Agatston CCP scores in participants of the NHLBI Family Heart Study (FHS). METHODS: During standardized clinical exams smoking habits were ascertained and CCP was quantified with cardiac computed tomography (CT). Among 4387 relationship pairs from 2128 Caucasian examinees variance component analysis was implemented in SOLAR to examine: (1) additive genotype-by-smoking status interaction using a variance component approach; (2) linkage analysis in the full sample and among smoking subsets defined by individual smoking exposure; (3) QTL-specific genotype-by-smoking interaction in the regions that appeared to differentiate between smoking strata. RESULTS: The prevalence of CCP (and median Agatston score) was 75% (184.6) in men and 48% (51.0) in women. We detected four genome-wide significant logarithm of odds (LOD) scores in samples stratified by individual smoking exposure: chromosome 4 at 122cM (nearest marker D4S2297; robust adjusted LOD=3.1; q=0.053), chromosome 6 at 99cM (nearest marker D6S1056; robust adjusted LOD=3.3; q=0.053), chromosome 11 at 19cM (nearest marker D11S199; robust adjusted LOD=4.0; q=0.02) and chromosome 13 at 77cM (nearest marker D13S892; robust adjusted LOD=3.1; q=0.053). Additive and QTL-specific genotype-by-smoking interaction was detected on chromosomes 4, 6, 11 and 13; all P<0.05. Three of the four QTLs identified in this report have been previously linked to atherosclerosis and harbor interesting candidate genes. CONCLUSIONS: These findings demonstrate the importance of considering complex interactions in the search for genes that influence the pathogenesis of CCP.

RESUMO

Cesium-137 (137Cs) is one of the most important nuclear fission elements that contaminated the environment after the explosion of the Chernobyl nuclear power plant in Ukraine (1986). The aim of the study was to compare the efficacy of two chelating agent, Prussian blue and apple-pectin on 137cesium decorporation in rats. Rats were intravenously injected with a solution of 137cesium (5 kBq per rat). Chelating agents, Prussian blue or apple-pectin were given immediately after Cs contamination and during 11 days by addition of each chelating agent in drinking water at a concentration corresponding to 400 mg kg(-1) day(-1). Efficiency was evaluated 11 days after contamination (at the end of treatment) through their ability to promote Cs excretion and to reduce the radionuclide accumulation in some retention compartments (blood, liver, kidneys, spleen, skeleton and in the remaining carcass). In these conditions after treatment with Prussian blue a fivefold increase in fecal excretion of Cs was observed and was associated with a reduction in the radionuclide retention in the main organs measured. In contrast, no significant differences were observed between untreated rats and rats treated with apple-pectin. These observations were discussed in terms of ability of pectins to bind Cs and compared to recently published results obtained after treatment of Cs-contaminated children with this chelate.

RESUMO

BACKGROUND: Population aging and shortage of organs for transplantation result in increasing numbers of kidneys retrieved from elderly donors. The aim of this study was to analyze donation of kidneys from donors after brain death (DBD) over the age of 60 years (≥60), comorbidities that affect decisions on retrieval, and early results of kidney transplantation. METHODS: Ninety-six potential DBD ≥60 and 309 aged 40-59 years (40-59) reported in Upper Silesia, Poland, from 2004 to 2013 were enrolled in the study. RESULTS: DBD >60 presented a higher rate of coexisting hypertension (53% vs 34%), limb ischemia (10% vs 1%), and past stroke (6% vs 1%) compared with DBD 40-59 (P < .05), but no differences were observed in serum creatinine concentration (85 vs 84 µmol/L), coexisting coronary disease (14% vs 6%), or diabetes (10% vs 4%). The decision of withdrawal from retrieval was more frequent in DBD ≥60 (16% vs 7%; P < .05). Twelve months after kidney transplantation, serum creatinine concentration was higher in recipients of kidneys from DBD ≥60 compared with DBD 40-59 (169 vs 138 µmol/L; P < .001). The survivals of recipients (93% vs 95%) and kidney grafts (90% vs 93%) as well as rates of proteinuria >1.0 g/24 h (6% vs 2%) did not differ between the groups. CONCLUSIONS: A higher rate of comorbidities in potential kidney DBD ≥60 results in a lower retrieval rate in these donors. The function of kidneys harvested from DBD ≥60 12 months after transplantation is worse than those from DBD 40-59, but still acceptable.

RESUMO

BACKGROUND: Hospital training called ETPOD-Essentials in Organ Donation-was introduced in Poland in 31 hospitals with under-utilized potential of donation. The aim of this study was to assess the effect in hospitals included and not included in program, before and after trainings. METHODS: The number of potential and effective donors, organs used, and number (%) of family refusals were compared at 10 and in 20 months after the training and in equal periods before. RESULTS: In trained hospitals, the number of potential donors increased (17% in 10 months, 10% in 20 months); in remaining hospitals, donors increased in 5% in both periods. In hospitals included in ETPOD, the number of effective donors increased (2% and 4.5%); in the whole country, donors also increased (5.6% and 2.7%). In ETPOD hospitals, the number of utilized organs increased (14.5% and 8.5%); in the rest, the increase was 3% and 7%. In trained hospitals, family refusals increased from 6.9% to 16.2% and from 8.9% to 10.7%; in the whole country, family refusals decreased from 11.7% to 11% in the short term and increased from 9.6% to 12.1% in the long term. CONCLUSIONS: In hospitals involved in the ETPOD program, the increase in organ donation is greater than in the rest of hospitals. Distinct benefit was observed in consent to organ donation.

RESUMO

OBJECTIVE: To examine patterns of familial aggregation and factors influencing onset age in a sample of siblings with PD. METHODS: Sibling pairs (n = 203) with PD were collected as part of the GenePD study. Standardized family history, medical history, and risk factor data were collected and analyzed. RESULTS: The mean age at onset was 61.4 years and did not differ according to sex, exposure to coffee, alcohol, or pesticides. Head trauma was associated with younger onset (p = 0.03) and multivitamin use with later onset (p = 0.007). Age at onset correlation between sibling pairs was significant (r = 0.56, p = 0.001) and was larger than the correlation in year of onset (r = 0.29). The mean difference in onset age between siblings was 8.7 years (range, 0 to 30 years). Female sex was associated with increased frequency of relatives with PD. The frequency of affected parents (7.0%) and siblings (5.1%) was increased when compared with frequency in spouses (2.0%). CONCLUSIONS: The greater similarity for age at onset than for year of onset in sibling pairs with PD, together with increased risk for biological relatives over spouses of cases, supports a genetic component for PD. Risk to siblings in this series is increased over that seen in random series of PD cases; however, patients in this sample have similar ages at onset and sex distribution as seen for PD generally. These analyses suggest that factors influencing penetrance are critical to the understanding of this disease.

RESUMO

The role of genetics in Parkinson disease (PD) continues to be an area of considerable interest and controversy. We collected information involving the nuclear families of 948 consecutively ascertained PD index cases from the University of Virginia (UVA) Health System, the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson (RWJ) School of Medicine, and Boston University (BU) School of Medicine. We performed a segregation analysis to assess evidence for the presence of a Mendelian pattern of familial transmission. The proportion of male (60.4%) and female (39.6%) cases, the mean age of onset (57.7 years), and the proportion of affected fathers (4.7%), mothers (6.6%), brothers (2.9%), and sisters (3.2%) were similar across the three sites. While most of the index cases were male, modestly more of the reported affected relatives were female. These analyses support the presence of a rare major Mendelian gene for PD in both the age-of-onset and susceptibility model. The age-of-onset model provides evidence for a gene that influences age-dependent penetrance of PD, influencing age of onset rather than susceptibility. We also found evidence for a Mendelian gene influencing susceptibility to the disease. It is not evident whether these two analyses are modeling the same gene or different genes with different effects on PD. The finding of significant genes influencing penetrance for PD raises the question of whether these may interact with environmental factors or other genes to increase the risk for PD. Such gene environment interactions, involving reduced penetrance in PD, may explain the low concordance rates among monozygotic twins for this disease.

RESUMO

Oxygen toxicity was studied in 26 canine isolated, perfused lung lobes which included nine control lobes, 13 lungs ventilated with FIO2 1.0 for 4 hours, and four lobes ventilated with FIN2 1.0 for 1 hour prior to 4 hours of FIO2 1.0 to evaluate the postulated protective effect of anoxia. A significant increase in wet weight was seen in the O2 ventilated lungs which did not alter pulmonary capillary isogravimetric pressure (PCI), alveolar-arterial oxygen gradient, or pulmonary vascular resistance. In contrast, preliminary N2 ventilation resulted in a significant increase in PCI and greater weight gain while pulmonary vascular resistance was reduced. Pulmonary compliance was reduced minimally in all groups. Anoxic ventilation not only failed to protect the isolated canine lung from presumed increased capillary permeability of oxygen toxicity, but seemed to contribute to the formation of interstitial pulmonary edema.

RESUMO

We have examined the effects of diabetes, fasting, and refeeding on Na+/K(+)-adenosine triphosphatase (ATPase) activity and its catalytic alpha II subunit gene expression in skeletal muscle. Two hypoinsulinemic states, streptozotocin-induced diabetes and 48-hour fasting caused a significant decrease (P less than .05) in skeletal muscle Na+/K(+)-ATPase activity and a marked increase (P less than .01) in the levels of alpha II subunit mRNA. A decrease in enzyme activity was observed on the 2nd and the 14th day of diabetes, whereas an increase in alpha II mRNA levels was found only on the 14th day. The levels of alpha I mRNA were not affected, while the levels of mRNA of the structural beta subunit were decreased on the 14th day of diabetes. Correction of hyperglycemia with insulin restored enzyme activity and alpha II isoform mRNA levels toward normal in diabetic animals. Refeeding for 48 or 72 hours restored these parameters to normal in skeletal muscle of previously fasting rats. These observations suggest that a decrease in muscle Na+/K(+)-ATPase activity may lead to a compensatory increase in its alpha II subunit gene expression. The levels of insulin and not of glycemia appear to be critical in modulating Na+/K(+)-ATPase activity and gene expression.

RESUMO

This study investigated changes in body composition, resting energy expenditure (REE), appetite, and mood in 128 obese women who were randomly assigned to 1 of 4 treatment conditions: diet alone, diet plus aerobic training, diet plus strength training, or diet combined with aerobic and strength training (i.e., combined training). All women received the same 48-week group behavioral program and were prescribed the same diet. Exercising participants were provided 3 supervised exercise sessions per week for the first 28 weeks and 2 sessions weekly thereafter. Participants across the 4 conditions achieved a mean weight loss of 16.5 +/- 6.8 kg at Week 24, which decreased to 15.1 +/- 8.4 kg at Week 48. There were no significant differences among conditions at any time in changes in weight or body composition. Women who received aerobic training displayed significantly smaller reductions in REE at Week 24 than did those who received strength training. There were no other significant differences among conditions at any time on this variable or in changes in appetite and mood.

RESUMO

DNA from non-diabetic Caucasians (n = 16), Blacks (n = 22), Hispanics (n = 13) and Japanese (n = 21), as well as DNA from 34 Caucasian, 19 Black, 19 Hispanic and 20 Japanese non-insulin-dependent diabetes mellitus (NIDDM) patients were examined for restriction fragment length polymorphism (RFLP) after digestion with enzymes BglII and XbaI, and hybridization with the glucose transporter probe, hGT2-2. There were significant differences in the incidence of the RFLPs between Caucasians and Blacks, both controls and patients with NIDDM. Digestion with XbaI revealed a higher incidence of the homozygotic state for allele I in NIDDM Caucasians (12 vs. 0%) than in controls. In NIDDM Blacks and Hispanics, we found a high incidence of a combination of two traits: 42% of the Black and 47% of the Hispanic NIDDM patients were homozygous for the BglII allele I and heterozygous for XbaI. Only 23% of non-NIDDM Blacks or Hispanics had this combination (P less than 0.05). There was no association between RFLP frequency and NIDDM among Japanese subjects. These data support the influence of race on both BglII and XbaI RFLPs. The homozygotes for XbaI in Caucasians and the presence of two specific traits in Blacks and Hispanics appear with higher frequency in NIDDM.

RESUMO

The authors present the results of spinal cord function evaluation in organ donors by examination of reflexes. The knee reflex and ankle jerk, as well as abdominal reflex and foot withdrawal reaction were tested in 31 donors. At least one of the above was seen in 25 individuals. It is suggested on the basis of data obtained not to hamper the transplant procedure in cases of tested reflex persistency when brain death is revealed on relevant examination.

RESUMO

Internal contamination by actinides following wounding may occur in nuclear fuel industry workers or subsequent to terrorist activities, causing dissemination of radioactive elements. Contamination by alpha particle emitting actinides can result in pathological effects, either local or distant from the site of entry. The objective of the present study was to develop a robust experimental approach in the rat for short- and long- term actinide contamination following wounding by incision of the skin and muscles of the hind limb. Anesthetized rats were contaminated with Mixed OXide (MOX, uranium, plutonium oxides containing 7.1% plutonium) or plutonium nitrate (Pu nitrate) following wounding by deep incision of the hind leg. Actinide excretion and tissue levels were measured as well as histological changes from 2 h to 3 mo. Humid swabs were used for rapid evaluation of contamination levels and proved to be an initial guide for contamination levels. Although the activity transferred from wound to blood is higher after contamination with a moderately soluble form of plutonium (nitrate), at 7 d most of the MOX (98%) or Pu nitrate (87%) was retained at the wound site. Rapid actinide retention in liver and bone was observed within 24 h, which increased up to 3 mo. After MOX contamination, a more rapid initial urinary excretion of americium was observed compared with plutonium. At 3 mo, around 95% of activity remained at the wound site, and excretion of Pu and Am was extremely low. This experimental approach could be applied to other situations involving contamination following wounding including rupture of the dermal, vascular, and muscle barriers.

RESUMO

PURPOSE: We investigated HbA1c's validity as a screening parameter for excluding dysglycemic states in the studied population. MATERIAL/METHODS: Sensitivity and specificity of HbA1c in some cut-off points were compared with diagnoses based on the oral glucose tolerance test (OGTT) in individuals diagnosed between 2009-2010. Receiver operating characteristic (ROC) analysis for HbA1c was conducted. HbA1c and OGGT measures were done in 441 people (253 women, 187 men, average age 40.1 years (18-79 years)). Based on the OGGT test 37 individuals were diagnosed as diabetic, 28 as impaired glucose tolerant (IGT) and 63 as having impaired fasting glycemia (IFG). RESULTS: A cut-off value of 6.5% HbA1c classifies diabetic subjects with a sensitivity of 45.9% and specificity of 97.5%. In the investigated population the best cut-off point (the highest sum of the sensitivity and specificity) was 5.9% HbA1c (sensitivity 86.6%, specificity 73%). HbA1c values excluding the risk of dysglycemic states have shown false negative rate in 31.9% when HbA1c was 5.5% and 10.6% when HbA1c was 5.0%. CONCLUSIONS: Our results indicate that in the investigated population the evaluation of the prevalence of type 2 diabetes using HbA1c values proposed by the American Diabetes Association (ADA) has unsatisfactory sensitivity and detects less than a half of cases of diabetes based on the OGTT diagnoses. HbA1c 5.7% does not have sufficient specificity to identify individuals not being at risk of any disorder of glucose metabolism.

RESUMO

BACKGROUND: As the disparity between the numbers of available organ donors and patients awaiting transplantation increases, different strategies have been proposed to extend the donor pool. Patients with acute kidney injury (AKI) developing during an intensive care unit (ICU) stay are often considered to be donors, but the long-term outcomes of such high-risk kidney transplantations is unknown. We analyzed the renal function and outcomes over 5 years of kidney grafts recovered from deceased donors diagnosed with AKI. MATERIALS AND METHODS: We collected data from 61 deceased kidney donors, identified in 1 ICU, and 120 kidney graft recipients who underwent transplantation between January 1999 and December 2006. Donors were stratified according to the RIFLE classification, based on their creatinine and urine output change from admission to the ICU and organ procurement. Recipient kidney graft function (eGFR) calculated according to the MDRD (Modification of Diet in Renal Disease) equation was estimated every 6 months. RESULTS: Among 61 donors, 10 (16.4%) developed AKI, including 7 classified as "risk", 2 as "injury," and 1 as "failure." The mean follow-up of kidney graft recipients was 49±18 months. The long-term risk for graft loss was significantly higher among the group of kidneys recovered from donors with AKI (27.8% vs 7.1%; P=.02; log-rank=0.07). Their excretory function was worse over the whole follow-up period. CONCLUSION: Patients with kidney grafts obtained from the donors with AKI showed a higher risk for graft loss and worse excretory function upon long-term follow-up.
