    Full Text Available Introduction : Coronary artery revascularization is indicated in patients with documented significant obstruction of coronary blood flow associated with a large area of myocardial ischemia and/or untreatable symptoms. There are a few invasive or noninvasive methods that can provide information about the functional results of coronary artery narrowing. The application of more than one method of ischemia detection in one patient to reevaluate the indications for revascularization is used in case of atypical or no symptoms and/or borderline stenosis. Aim : To evaluate whether the results of cardiac magnetic resonance need to be reconfirmed by the invasive functional method. Material and methods : The hospital database revealed 25 consecutive patients with 29 stenoses who underwent cardiac magnetic resonance (CMR and fractional flow reserve (FFR between the end of 2010 and the end of 2014. The maximal time interval between CMR and FFR was 6 months. None of the patients experienced any clinical events or underwent procedures on coronary arteries between the studies. Results: According to the analysis, the agreement of CMR perfusion with the FFR method was at the level of 89.7%. Assuming that FFR is the gold standard in assessing the severity of stenoses, the sensitivity of CMR perfusion was 90.9%. The percentage of non-severe lesions which were correctly identified in CMR was 88.9%. Conclusions : The study shows that CMR perfusion is a highly sensitive method to detect hemodynamically significant CAD and exclude nonsevere lesions. With FFR as the reference standard, the diagnostic accuracy of MR perfusion to detect ischemic CAD is high.

    Full Text Available A prospective observational study was conducted in a tertiary care teaching hospital from August 2008 to August 2009 to explore the independent predictors of adverse outcome in the patients with confirmed/probable viral encephalitis. The primary outcome variable was the incidence of adverse outcomes defined as death or severe neurological deficit such as loss of speech, motor deficits, behavioural problems, blindness, and cognitive impairment. Patients with confirmed or probable viral encephalitis were classified into two groups based on their Z-score of weight-for-age as per WHO growth charts. Group I. Patients with confirmed or probable viral encephalitis with weight-for-age (W/A Z-scores below −2SD were classified as undernourished. Group II. Patients with confirmed or probable viral encephalitis were classified as having normal nutritional status (weight-for-age Z-score >−2SD. A total of 114 patients were classified as confirmed or probable viral encephalitis based on detailed investigations. On multivariate logistic regression, undernutrition (adjusted OR: 5.05; 95% CI: 1.92 to 13.44 and requirement of ventilation (adjusted OR: 6.75; 95% CI: 3.63 to 77.34 were independent predictors of adverse outcomes in these patients. Thus, the results from our study highlight that the association between undernutrition and adverse outcome could be extended to the patients with confirmed/probable viral encephalitis.

    Because of the exist of complex matrix, the confirming indicators of qualitative results for toxic substances in biological samples by chromatography-mass spectrometry are different from that in non-biological samples. Even in biological samples, the confirming indicators are different in various application areas. This paper reviews the similarities and differences of confirming indicators for the analyte in biological samples by chromatography-mass spectrometry in the field of forensic toxicological analysis and other application areas. These confirming indicators include retention time (RT), relative retention time (RRT), signal to noise (S/N), characteristic ions, relative abundance of characteristic ions, parent ion-daughter ion pair and abundance ratio of ion pair, etc. Copyright© by the Editorial Department of Journal of Forensic Medicine.

    Genital dissatisfaction is an important reason for transmen to undergo genital gender-confirming surgery (GCS; phalloplasty or metoidioplasty). However, little is known about motives for choosing specific techniques, how transmen benefit postoperatively, and whether psychosexual outcomes improve. To evaluate motivations for and psychosexual outcomes after GCS. A longitudinal study of 21 transmen at least 1 year after GCS was conducted. Participants were recruited through their surgeon. Data were collected when they applied for surgery and at least 1 year after surgery. Data collection included semistructured questionnaires on motivations for surgery, postoperative experiences, and standardized measures of psychological symptoms, body image, self-esteem, sexuality, and quality of life (pre- and postoperative). Information on surgical complications and corrections was retrieved from medical records. Most participants underwent phalloplasty with urethral lengthening using a radial forearm flap. Although problematic voiding symptoms were prevalent, many participants were satisfied with their penile function. The strongest motivations to pursue penile surgery were confirmation of one's identity (100%), enabling sexual intercourse (78%), and voiding while standing (74%). No significant differences between postoperative and reference values were observed for standardized measures. After surgery, transmen were more sexually active (masturbation and with a partner) and used their genitals more frequently during sex compared with before surgery (31-78%). The present study provides input for preoperative decision making: (i) main motives for surgery include identity confirmation, voiding, and sexuality, (ii) surgery can result in more sexual activity and genital involvement during sex, although some distress can remain, but (iii) complications and voiding symptoms are prevalent. Study strengths include its longitudinal design and the novelty of the studied outcomes. The main

    Patients with renal disease typically have severely calcified peripheral arterial disease. As a result, this population may have worse clinical outcomes following endovascular intervention compared to patients without renal insufficiency. Clinical trials typically exclude this patient population. Analysis of the CONFIRM I-III registries revealed 1105 patients with renal disease (1777 lesions) and 1969 patients without renal disease (2907 lesions) who underwent orbital atherectomy. This subanalysis compared the composite procedural complication rate including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation in patients with and without renal disease. Patients with renal disease had a higher prevalence of diabetes (Patherectomy resulted in similar low rates of procedural complications in the renal disease group compared with the non-renal disease group despite more unfavorable baseline clinical and lesion characteristics in the renal disease group.

    The results of a detailed analysis performed on the data obtained in the 248 Cm( 48 Ca,4n) 292 116 reaction is presented. This analysis is independent of the original data analysis performed in Dubna in which three separate decay chains were found. Each decay chain began with an evaporation residue followed by three α decays and ended in a spontaneous fission event, all correlated in time and position. The analysis presented confirms that the three events are present in the data. A summary of the three events will be given as well as a description of the analysis performed

    To compare the acute outcomes of orbital atherectomy treatment in diabetic vs. non-diabetic patients with peripheral artery disease (PAD). The CONFIRM registry series contained 1842 diabetic patients (1111 men; mean age 70.6±10.2 years) with 2819 lesions and 1247 non-diabetic patients (732 men; mean age 72.9±10.7 years) with 1885 lesions. The composite rate of procedure-related complications, including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation, was analyzed for the diabetic and non-diabetic groups. Diabetics were younger but had a higher prevalence of coronary artery disease (patherectomy resulted in similar low procedure-related complication rates in both the diabetic and non-diabetic groups, despite diabetics having more unfavorable baseline clinical and lesion characteristics. This study suggests that orbital atherectomy is a safe and effective treatment modality in both the diabetic and the non-diabetic populations.

  10. Confirmation of the Z(4430)- resonance and other exotic meson results from the LHCb experiment

    The LHCb experiment at CERN has recently confirmed the existence of the exotic Z(4430)- state first observed by the Belle experiment in 2008. Its quantum numbers have been measured and the resonant nature of this state has been demonstrated for the first time. As it is charged, the Z(4430)- cannot be classified as a conventional charmonium (ccbar) state, making it a candidate for an exotic resonance composed of four quarks (ccbar udbar). This talk will outline the history of the Z(4430)-, its possible interpretations and describe how the signature of this exotic state can be extracted from the large sample of B0 -> psi(2S) K+pi- decays that LHCb has collected during Run-1 of the LHC. I will also describe recent LHCb results that probe the nature of the exotic X(3872) particle and help to clarify our understanding of the f0(500) and f0(980) scalar mesons that have long thought to be four quark states.

    Full Text Available The hydrological responses of a catchment are sensitive to, and strongly coupled to, land use and climate, and changes thereof. The hydrological responses to the impacts of changing land use and climate will be the result of complex interactions, where the change in one may moderate or exacerbate the effects of the other. Further difficulties in assessing these interactions are that dominant drivers of the hydrological system may vary at different spatial and temporal scales. To assess these interactions, a process-based hydrological model, sensitive to land use and climate, and changes thereof, needs to be used. For this purpose the daily time step ACRU model was selected. However, to be able to use a hydrological model such as ACRU with confidence its representation of reality must be confirmed by comparing simulated output against observations across a range of climatic conditions. Comparison of simulated against observed streamflow was undertaken in three climatically diverse South African catchments, ranging from the semi-arid, sub-tropical Luvuvhu catchment, to the winter rainfall Upper Breede catchment and the sub-humid Mgeni catchment. Not only do the climates of the catchments differ, but their primary land uses also vary. In the upper areas of the Mgeni catchment commercial plantation forestry is dominant, while in the middle reaches there are significant areas of commercial plantation sugarcane and urban areas, while the lower reaches are dominated by urban areas. The Luvuvhu catchment has a large proportion of subsistence agriculture and informal residential areas. In the Upper Breede catchment in the Western Cape, commercial orchards and vineyards are the primary land uses. Overall the ACRU model was able to represent the high, low and total flows, with satisfactory Nash-Sutcliffe efficiency indexes obtained for the selected catchments.

    In 1992, the Gallex experiment announced the first observation of the neutrinos produced in the primary proton-proton fusion reaction in the core of the Sun, reaction at the origin of the energy production by our star (September 1992, page 1). The Gallex team stressed that the observed neutrino flux was only about two-thirds of the predicted level, confirming the deficit observed by the two pioneering experiments, Ray Davis' chlorine-based detector in the USA and the Kamiokande study in Japan (which are only sensitive to neutrinos from subsidiary solar fusion processes). This deficit demands explanation, and could considerably modify our understanding of how stars shine and/or of neutrino physics. But before drawing conclusions, the Gallex result had to be checked. Gallex, installed in the Italian Gran Sasso underground Laboratory, is a radiochemical experiment using neutrino interactions to transform gallium-71 into germanium-71. The latter is radioactive and decays with a half-life of 11.4 days. Counting the germanium-71 atoms extracted from the target tank measures the neutrino flux to which the detector is exposed. Neutrinos are famous for their reluctance to interact. 65 billion per square centimetre per second on the surface of the Earth produce only one germanium-71 atom in the Gallex target containing 30 tons of gallium. This is at the limit of homeopathy (extracting few atoms of germanium-71 from a solution containing 10 30 atoms) and needs careful checking. Since it is not possible to switch off the Sun, the only recourse was to build an artificial neutrino source more powerful than the Sun as a benchmark. This was done last summer. Last May, 36 kilograms of chromium grains were placed in the Siloe reactor of the French Commissariat à l'énergie atomique, Grenoble. The chromium had been previously enriched to 40% chromium-50 by the Kurchatov Institute in Moscow (natural chromium contains only 4.5% chromium-50). A dedicated core was built for

    Increased cannabis potency has renewed concerns that secondhand exposure to cannabis smoke can produce positive drug tests. A systematic study was conducted of smoke exposure on drug-free participants. Six experienced cannabis users smoked cannabis cigarettes (5.3% THC in Session 1 and 11.3% THC in Sessions 2 and 3) in a sealed chamber. Six non-smokers were seated with smokers in an alternating manner. Sessions 1 and 2 were conducted with no ventilation and ventilation was employed in Session 3. Non-smoking participant specimens (collected 0–34 h) were analyzed with four immunoassays at different cutoff concentrations (20, 50, 75 and 100 ng/mL) and by GC-MS (LOQ = 0.75 ng/mL). No presumptive positives occurred for non-smokers at 100 and 75 ng/mL; a single positive occurred at 50 ng/mL; and multiple positives occurred at 20 ng/mL. Maximum THCCOOH concentrations by GC-MS for non-smokers ranged from 1.3 to 57.5 ng/mL. THCCOOH concentrations generally increased with THC potency, but room ventilation substantially reduced exposure levels. These results demonstrate that extreme cannabis smoke exposure can produce positive urine tests at commonly utilized cutoff concentrations. However, positive tests are likely to be rare, limited to the hours immediately post-exposure, and occur only under environmental circumstances where exposure is obvious. PMID:25326203

    Previous studies of psychosocial work factors have indicated their importance for workers' health. However, to what extent health problems can be attributed to the nature of the work environment or other psychosocial factors is not clear. No previous systematic review has used inclusion criteria based on specific medical evaluation of work-related health outcomes and the use of validated instruments for the assessment of the psychosocial (work) environment. The aim of this systematic review is to summarize the evidence assessing the relationship between the psychosocial work environment and workers' health based on studies that used standardized and validated instruments to assess the psychosocial work environment and that focused on medically confirmed health outcomes. A systematic review of the literature was carried out by searching the databases PubMed, B-ON, Science Direct, Psycarticles, Psychology and Behavioral Sciences Collection and the search engine (Google Scholar) using appropriate words for studies published from 2004 to 2014. This review follows the recommendations of the Statement for Reporting Systematic Reviews (PRISMA). Studies were included in the review if data on psychosocial validated assessment method(s) for the study population and specific medical evaluation of health-related work outcome(s) were presented. In total, the search strategy yielded 10,623 references, of which 10 studies (seven prospective cohort and three cross-sectional) met the inclusion criteria. Most studies (7/10) observed an adverse effect of poor psychosocial work factors on workers' health: 3 on sickness absence, 4 on cardiovascular diseases. The other 3 studies reported detrimental effects on sleep and on disease-associated biomarkers. A more consistent effect was observed in studies of higher methodological quality that used a prospective design jointly with the use of validated instruments for the assessment of the psychosocial (work) environment and clinical

    BACKGROUND AND PURPOSE To determine the effect of IV-tPA on outcomes in patients with severe major anterior circulation ischemic stroke. METHODS Prospectively, 649 acute stroke patients had admission NIH stroke scale scores (NIHSS), non-contrast CT, CT angiography (CTA), and 6-month outcome assessed using modified Rankin scale (mRS). IV-tPA treatment decisions were made prior to CTA, at the time of non-contrast CT scanning, as per routine clinical protocol. Severe symptoms were defined as NIHSS>10. Poor outcome was defined as mRS>2. Major occlusions were identified on CTA. Univariate and multivariate stepwise-forward logistic regression analyses of the full cohort were performed. RESULTS Of 649 patients, 188 (29%) presented with NIHSS>10, and 64/188 (34%) of these received IV-tPA. Admission NIHSS, large artery occlusion, and IV-tPA all independently predicted good outcomes, however a significant interaction existed between IV-tPA and occlusion (p10 patients with anterior circulation occlusion, twice the percentage had good outcomes if they received IV-tPA (17/49, 35%), than if they did not (13/77, 17%; p=0.031). The “number needed to treat” was 7 (95% CI = 3–60). CONCLUSIONS IV-tPA treatment resulted in significantly more good outcomes in severely symptomatic stroke patients with major anterior circulation occlusions. The 35% good outcome rate was similar to rates found in endovascular therapy trials. Vascular imaging may help in patient selection and stratification for trials of IV-thrombolytic and endovascular therapies. PMID:24003051

    Patients with suspected or confirmed non-ST-elevation acute coronary syndrome (ACS) constitute a large and heterogeneous group. Measurements of renal function such as serum creatinine and estimation of creatinine clearance carry independent prognostic information in this population. Cystatin C is a new and better marker of renal function than creatinine. The aim was therefore to evaluate the prognostic value of cystatin C in this population. Cystatin C was analyzed on admission in 726 patients admitted because of symptoms suggestive of an acute coronary syndrome and no ST-segment elevations. Patients were followed up with regard to death and myocardial infarction for a median of 40 and 6 months, respectively. The median cystatin C level was 1.00 mg/L (25th to 75th percentile, 0.83 to 1.24 mg/L). The risk of death during follow-up increased with increasing levels of cystatin C. In the group with non-ST-elevation ACS, patients in the second, third, and fourth quartiles had a relative risk of subsequent death of 1.8 (95% CI, 0.6 to 5.3), 3.2 (95% CI, 1.2 to 8.5), and 11.7 (95% CI, 4.7 to 29.3) compared with the lowest quartile. In Cox regression models including well-known predictors of outcome, cystatin C level was independently associated with mortality but not with the risk of subsequent myocardial infarction. In a comparison of the markers of renal function in receiver-operating curve analyses, cystatin C had the best ability to discriminate between survivors and nonsurvivors. A single measurement of cystatin C will substantially improve the early risk stratification of patients with suspected or confirmed non-ST-elevation ACS.

    Management of lymph nodes in radiotherapy for prostate cancer is an issue for curative intent. To find the influence of lymph nodes, patients with T1-T3 prostate cancer and surgically confirmed negative nodes were treated with radiotherapy. After lymphadenectomy, 118 patients received photon beam radiotherapy with 66 Gy to the prostate. No adjuvant treatment was performed until biochemical failure. After failure, hormone therapy was administered. Follow-up period was 57 months (mean). Biochemical failure occurred in 47 patients. Few failures were observed in patients with low (24%) and intermediate risks (14%). In contrast, 64% of high-risk patients experienced failure, 97% of whom showed until 36 months. Most patients with failure responded well to hormone therapy. After 15 months (mean), a second biochemical failure occurred in 21% of patients who had the first failure, most of them were high risk. Factors involving failure were high initial and nadir prostate-specific antigen, advanced stage, short prostate-specific antigen-doubling time and duration between radiation and first failure. Failure showed an insufficient reduction in prostate-specific antigen after radiotherapy. Factor for second failure was prostate-specific antigen-doubling time at first failure. Half of high-risk patients experienced biochemical failure, indicating one of the causes involves factors other than lymph nodes. Low-, intermediate- and the other half of high-risk patients did not need to take immediate hormone therapy after radiotherapy. After failure, delayed hormone therapy was effective. Prostate-specific antigen parameters were predictive factors for further outcome. (author)

    Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome comprising familial/genetic HLH (FHL) and secondary HLH. In the HLH-94 study, with an estimated 5-year probability of survival (pSu) of 54% (95% confidence interval, 48%-60%), systemic therapy included etoposide, dexamethasone, and, from week 9, cyclosporine A (CSA). Hematopoietic stem cell transplantation (HSCT) was indicated in patients with familial/genetic, relapsing, or severe/persistent disease. In HLH-2004, CSA was instead administered upfront, aiming to reduce pre-HSCT mortality and morbidity. From 2004 to 2011, 369 children aged <18 years fulfilled HLH-2004 inclusion criteria (5 of 8 diagnostic criteria, affected siblings, and/or molecular diagnosis in FHL-causative genes). At median follow-up of 5.2 years, 230 of 369 patients (62%) were alive (5-year pSu, 61%; 56%-67%). Five-year pSu in children with (n = 168) and without (n = 201) family history/genetically verified FHL was 59% (52%-67%) and 64% (57%-71%), respectively (familial occurrence [n = 47], 58% [45%-75%]). Comparing with historical data (HLH-94), using HLH-94 inclusion criteria, pre-HSCT mortality was nonsignificantly reduced from 27% to 19% (P = .064 adjusted for age and sex). Time from start of therapy to HSCT was shorter compared with HLH-94 (P = .020 adjusted for age and sex) and reported neurological alterations at HSCT were 22% in HLH-94 and 17% in HLH-2004 (using HLH-94 inclusion criteria). Five-year pSu post-HSCT overall was 66% (verified FHL, 70% [63%-78%]). Additional analyses provided specific suggestions on potential pre-HSCT treatment improvements. HLH-2004 confirms that a majority of patients may be rescued by the etoposide/dexamethasone combination but intensification with CSA upfront, adding corticosteroids to intrathecal therapy, and reduced time to HSCT did not improve outcome significantly.

    Introduction Campylobacteriosis is one of the leading causes of gastroenteritis worldwide. This study describes the epidemiology of laboratory-confirmed Campylobacter diarrheal infections in two facility-based surveillance sites in Guatemala. Methods Clinical, epidemiologic, and laboratory data were collected on patients presenting with acute diarrhea from select healthcare facilities in the departments of Santa Rosa and Quetzaltenango, Guatemala, from January 2008 through August 2012. Stool specimens were cultured for Campylobacter and antimicrobial susceptibility testing was performed on a subset of isolates. Multidrug resistance (MDR) was defined as resistance to ≥3 antimicrobial classes. Results Campylobacter was isolated from 306 (6.0%) of 5137 stool specimens collected.

    Patients with peripheral arterial disease (PAD) can be classified into groups based upon the severity of the disease using the Rutherford classification system. This analysis compares the procedural outcomes of PAD patients treated with orbital atherectomy stratified by Rutherford class (1-3 = intermittent claudication; 4-6 = critical limb ischemia [CLI]), and acute angiographic outcomes of these patients stratified by degree of lesion calcification. The CONFIRM registry series was analyzed and included 1697 patients with intermittent claudication (Rutherford class 1-3) and 1320 patients with CLI (Rutherford class 4-6) treated with orbital atherectomy. The composite rate of dissection, perforation, slow-flow, vessel closure, spasm, embolism, and thrombus formation was compared between claudicants and CLI patients with varying degrees of lesion calcification. Patients with CLI were older and had a higher prevalence of diabetes, coronary artery disease, and renal disease (Patherectomy resulted in similar low procedural complication rates in the CLI group compared with the claudicant group. These results suggest that orbital atherectomy is safe and effective for treating calcified lesions in high-risk patients with varying severity of PAD symptoms.

    To compare the acute procedure and angiographic outcomes of peripheral artery disease (PAD) patients treated with orbital atherectomy stratified by gender. The CONFIRM I, II, and III registries are US multicenter, nonrandomized, all-comers registries of PAD patients who were treated with orbital atherectomy. All patients with gender specified in the registry database were included in the current analysis, which compared the final residual stenosis achieved after atherectomy and the rate of acute complications in female and male patients. The 3 registries included 3131 patients with 4761 lesions: 1261 women (mean age 73.2 ± 10.7 years) with 1874 lesions and 1870 men (mean age 70.4 ± 10.2) with 2887 lesions. The women were older (p atherectomy in both men and women; however, women had a higher rate of dissection (all types). This difference is likely because of the older age and higher percentage of critical limb ischemia in women in this cohort. These results, however, suggest that additional studies should be completed to further understand the increased risks for women vs. men during endovascular procedures. © The Author(s) 2015.

    Campylobacteriosis is one of the leading causes of gastroenteritis worldwide. This study describes the epidemiology of laboratory-confirmed Campylobacter diarrheal infections in two facility-based surveillance sites in Guatemala. Clinical, epidemiologic, and laboratory data were collected on patients presenting with acute diarrhea from select healthcare facilities in the departments of Santa Rosa and Quetzaltenango, Guatemala, from January 2008 through August 2012. Stool specimens were cultured for Campylobacter and antimicrobial susceptibility testing was performed on a subset of isolates. Multidrug resistance (MDR) was defined as resistance to ≥3 antimicrobial classes. Campylobacter was isolated from 306 (6.0%) of 5137 stool specimens collected. For children Guatemala; antimicrobial resistance was high, and treatment regimens in the ambulatory setting which included metronidazole and trimethoprim-sulfamethoxazole and lacked oral rehydration were sub-optimal.

    This study aimed to examine whether (a) exposure to universal newborn hearing screening (UNHS) and b) early confirmation of hearing loss were associated with benefits to expressive and receptive language outcomes in the teenage years for a cohort of spoken language users. It also aimed to determine whether either of these two variables was associated with benefits to relative language gain from middle childhood to adolescence within this cohort. The participants were drawn from a prospective cohort study of a population sample of children with bilateral permanent childhood hearing loss, who varied in their exposure to UNHS and who had previously had their language skills assessed at 6-10 years. Sixty deaf or hard of hearing teenagers who were spoken language users and a comparison group of 38 teenagers with normal hearing completed standardized measures of their receptive and expressive language ability at 13-19 years. Teenagers exposed to UNHS did not show significantly better expressive (adjusted mean difference, 0.40; 95% confidence interval [CI], -0.26 to 1.05; d = 0.32) or receptive (adjusted mean difference, 0.68; 95% CI, -0.56 to 1.93; d = 0.28) language skills than those who were not. Those who had their hearing loss confirmed by 9 months of age did not show significantly better expressive (adjusted mean difference, 0.43; 95% CI, -0.20 to 1.05; d = 0.35) or receptive (adjusted mean difference, 0.95; 95% CI, -0.22 to 2.11; d = 0.42) language skills than those who had it confirmed later. In all cases, effect sizes were of small size and in favor of those exposed to UNHS or confirmed by 9 months. Subgroup analysis indicated larger beneficial effects of early confirmation for those deaf or hard of hearing teenagers without cochlear implants (N = 48; 80% of the sample), and these benefits were significant in the case of receptive language outcomes (adjusted mean difference, 1.55; 95% CI, 0.38 to 2.71; d = 0.78). Exposure to UNHS did not account for significant

    This analysis compares the procedural and acute angiographic outcomes in patients with critical limb ischemia (CLI) treated with orbital atherectomy in above-the-knee (ATK)/popliteal (POP) lesions versus below-the-knee (BTK) lesions. Lesion location affects the procedural outcomes and the opportunity for limb salvage in patients with CLI suffering from peripheral artery disease (PAD). The CONFIRM registry series was analyzed and includes 1109 real-world patients (1544 lesions) suffering from CLI treated with orbital atherectomy. The rates of dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation were compared between CLI patients with ATK/POP lesions and BTK lesions. Patients with ATK/POP lesions had a higher final residual stenosis (10 vs. 9%; P = 0.004) and use of more adjunctive therapies (e.g. balloons and stents; 1.3 vs. 1.1%; P atherectomy was successful in CLI patients regardless of lesion location. BTK lesions were associated with increased rates of perforation, slow flow and spasm which may be explained by more challenging procedural characteristics in these patients such as smaller vessel size and tortuosity. The higher incidence of emboli in ATK/POP lesions is most likely attributed to the higher prevalence of severe calcium observed in this cohort. © 2015 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis. All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.

    Full Text Available Purpose: To demonstrate the safety and outcome of a surgical approach that uses pars plicata site for anterior vitrectomy during phacoemulsification procedure complicated by posterior capsule rupture and residual cortical matter. Design: Single center, retrospective, interventional, noncomparative study. Materials and Methods: Medical records of a consecutive series of 35 eyes of 35 patients who underwent pars plicata anterior vitrectomy (PPAV were reviewed. The main outcome measures were corrected and uncorrected distance visual acuity (CDVA, UDVA, early and late postoperative complications and intraocular pressure (IOP. Ultrasound biomicroscopic (UBM evaluation of sclerotomy site and spectral domain optical coherence tomography analysis for central macular thickness (CMT was performed. The final visual outcome at 2 years was evaluated. Results: At 2 years follow-up, the mean postoperative UDVA (logarithm of the minimum angle of resolution [logMAR] and CDVA (logMAR was 0.49 ± 0.26 and 0.19 ± 0.14, respectively. There was no significant change in the IOP (P = 0.061 and the mean CMT at 2 years was 192.5 ± 5.54 mm. The postoperative UBM image of the sclerotomy site at 8 weeks demonstrated a clear wound without any vitreous adhesion or incarceration. Intraoperative hyphema was seen in 1 (2.8% case and postoperative uveitis was seen in 2 (5.7% cases, which resolved with medications. No case of an iatrogenic retinal break or retinal detachment was reported. Conclusions: PPAV enables a closed chamber approach, allows thorough cleanup of vitreous in the pupillary plane and anterior chamber and affords better access to the subincisional and retropupillary cortical remnant with a significant visual outcome and an acceptable complication rate.

    Data on the outcomes of elderly patients with peripheral arterial disease (PAD) who undergo orbital atherectomy are limited. This analysis compares the procedural and acute angiographic outcomes of PAD patients treated with orbital atherectomy stratified by age (≥ 75 years of age [elderly] vs atherectomy. The composite rate of adverse events including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation was compared between groups. Elderly patients had a higher proportion of females (47.5% vs 35.3%; Patherectomy resulted in similar composite rates of adverse events despite the elderly having unfavorable baseline Rutherford classification and lesion characteristics. The higher rate of perforation may be explained by longer and more below-the-knee lesions.

    This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions). The primary endpoint was angiographic complication, defined as the composite of dissection, perforation, slow flow, closure, spasm, embolism, or thrombosis. The CFA group had more patients with Rutherford class 4 and shorter lesion length. The CFA group had a higher final residual stenosis, shorter total run time, and shorter total inflation time. The primary endpoint was lower in the CFA group compared with the SFA group (17% vs 24%, p=0.02), driven by a lower dissection rate (10% vs 15%, p=0.04). Plaque modification of the CFA with orbital atherectomy was safe and compared favorably with SFA disease. The need for bail-out stenting was low. A randomized trial is needed to determine the ideal treatment strategy for calcified CFA disease.

    Full Text Available Petroclival meningiomas represent only 10% of all meningiomas located in the posterior fossa, but are some of the most formidable challenges in skull base surgery. We described our recent experience (2005-September2014 regarding the surgery of these tumors. We retrospectively analyzed surgical results and outcome in 11 cases of petroclival meningiomas. Most common symptoms in our series were headache and gait disturbance, while cranial nerves palsies represented the most common presenting signs. There were 8 females and 3 males, and the mean age was 52 years. Surgical approaches chosen for petroclival meningiomas in our series were retrosigmoid (9 patients and subtemporal transtentorial (2 patients. We achieved total tumor resection in 5 cases (45% and subtotal resection in 6 cases (55%. Overall outcome (total/subtotal resection was good in 6 cases, fair in 3 cases and poor in one case. One postoperative death occurred due to hemorrhagic midbrain infarction (9%. Complications were usually related to cranial nerve deficits: loss of hearing (2 patients, paresis of trochlear nerve (1 patient, trigeminal nerve (3 patients and facial nerve (1 patient. In 4 patients these cranial nerves deficits were transient. In one case, a patient developed postoperative hydrocephalus and needed shunt placement. Despite the fact that complications can be disastrous, we considered that an appropriate approach, combined with microsurgical techniques and a better understanding of the anatomy, greatly decrease the incidence and severity of complications and make feasible a total tumor resection.

    We tested the hypothesis that the early improvement in mood after the first hour of bright light treatment compared to control dim-red light would predict the outcome at six weeks of bright light treatment for depressed mood in patients with Seasonal Affective Disorder (SAD). We also analyzed the value of Body Mass Index (BMI) and atypical symptoms of depression at baseline in predicting treatment outcome. Seventy-eight adult participants were enrolled. The first treatment was controlled crossover, with randomized order, and included one hour of active bright light treatment and one hour of control dim-red light, with one-hour washout. Depression was measured on the Structured Interview Guide for the Hamilton Rating Scale for Depression-SAD version (SIGH-SAD). The predictive association of depression scores changes after the first session. BMI and atypical score balance with treatment outcomes at endpoint were assessed using multivariable linear and logistic regressions. No significant prediction by changes in depression scores after the first session was found. However, higher atypical balance scores and BMI positively predicted treatment outcome. Absence of a control intervention for the six-weeks of treatment (only the first session in the laboratory was controlled). Exclusion of patients with comorbid substance abuse, suicidality and bipolar I disorder, and patients on antidepressant medications, reducing the generalizability of the study. Prediction of outcome by early response to light treatment was not replicated, and the previously reported prediction of baseline atypical balance was confirmed. BMI, a parameter routinely calculated in primary care, was identified as a novel predictor, and calls for replication and then exploration of possible mediating mechanisms.

    The gas/condensate pipe line under investigation is a 12 inch diameter, 48 km ASTM, A106 steel pipeline, carrying hydrocarbons containing wet CO2 and H2S.The pipe line had exploded in a region 100m distance from its terminal; after 24 years of service. Hydrogen induced cracking (HIC) and sour gas corrosion were expected due to the presence of wet H2S in the gas analysis. In other areas of pipe line ultrasonic testing was performed to determine whether the pipeline can be re-operated. The results have shown presence of internal planner defects, this was attributed to the existence of either laminations, type II inclusions or some service defects such as HIC and step wise cracking (SWC).Metallurgical investigations were conducted on fractured samples as per NACE standard (TM-0284-84). The obtained results had shown macroscopic cracks in the form of SWC, microstructure of steel had MnS inclusions. Crack sensitivity analyses were calculated and the microhardness testing was conducted. These results had confirmed that the line material was suffering from sour gas deteriorations. This paper correlates the field UT inspection findings with those methods investigated in the laboratory. Based on the results obtained a new HIC resistance material pipeline needs to be selected.

    Full Text Available Abstract Background High grade primary bone sarcomas are rare cancers that affect mostly children and young adults. Osteosarcoma and Ewing sarcoma are the most common histological subtypes in this age group, with current multimodality treatment strategies achieving 55-70% overall survival. As there remains an urgent need to develop new therapeutic interventions, we have reviewed published phase I/II trials that have been reported for osteosarcoma and Ewing sarcoma in the last twenty years. Results We conducted a literature search for clinical trials between 1990 and 2010, either for trials enrolling bone sarcoma patients as part of a general sarcoma indication or trials specifically in osteosarcoma and Ewing sarcoma. We identified 42 clinical trials that fulfilled our search criteria for general sarcoma that enrolled these patient groups, and eight and twenty specific trials for Ewing and osteosarcoma patients, respectively. For the phase I trials which enrolled different tumour types our results were incomplete, because the sarcoma patients were not mentioned in the PubMed abstract. A total of 3,736 sarcoma patients were included in these trials over this period, 1,114 for osteosarcoma and 1,263 for Ewing sarcoma. As a proportion of the worldwide disease burden over this period, these numbers reflect a very small percentage of the potential patient recruitment, approximately 0.6% for Ewing sarcoma and 0.2% for osteosarcoma. However, these data show an increase in recent activity overall and suggest there is still much room for improvement in the current trial development structures. Conclusion Lack of resources and commercial investment will inevitably limit opportunity to develop sufficiently rapid improvements in clinical outcomes. International collaboration exists in many well founded co-operative groups for phase III trials, but progress may be more effective if there were also more investment of molecular and translational research into

    Yucca Mountain license application identified a broad suite of monitoring activities. A revision of the plan was expected to winnow the number of activities down to a manageable size. As a result, an objective process for the next stage of performance confirmation planning was developed as an integral part of an overarching long-term testing and monitoring strategy. The Waste Isolation Pilot Plant compliance monitoring program at once reflects its importance to stakeholders while demonstrating adequate understanding of relevant monitoring parameters. The compliance criteria were stated by regulation and are currently monitored as part of the regulatory rule for disposal. At the outset, the screening practice and parameter selection were not predicated on a direct or indirect correlation to system performance metrics, as was the case for Yucca Mountain. Later on, correlation to performance was established, and the Waste Isolation Pilot Plant continues to monitor ten parameters originally identified in the compliance certification documentation. The monitoring program has proven to be effective for the technical intentions and societal or public assurance. The experience with performance confirmation in the license application process for Yucca Mountain helped identify an objective, quantitative methodology for this purpose. Revision of the existing plan would be based on findings of the total system performance assessment. Identification and prioritization of confirmation activities would then derive from performance metrics associated with performance assessment. Given the understanding of repository performance confirmation, as reviewed in this paper, it is evident that the performance confirmation program for the Yucca Mountain project could be readily re-engaged if licensing activities resumed.

  20. Exploring the Great Schism in the Social Sciences: Confirmation Bias and the Interpretation of Results Relating to Biological Influences on Human Behavior and Psychology.

    Winking, Jeffrey

    2018-01-01

    The nature-nurture debate is one that biologists often dismiss as a false dichotomy, as all phenotypic traits are the results of complex processes of gene and environment interactions. However, such dismissiveness belies the ongoing debate that is unmistakable throughout the biological and social sciences concerning the role of biological influences in the development of psychological and behavioral traits in humans. Many have proposed that this debate is due to ideologically driven biases in the interpretation of results. Those favoring biological approaches have been accused of a greater willingness to accept biological explanations so as to rationalize or justify the status quo of inequality. Those rejecting biological approaches have been accused of an unwillingness to accept biological explanations so as to attribute inequalities solely to social and institutional factors, ultimately allowing for the possibility of social equality. While it is important to continue to investigate this topic through further research and debate, another approach is to examine the degree to which the allegations of bias are indeed valid. To accomplish this, a convenience sample of individuals with relevant postgraduate degrees was recruited from Mechanical Turk and social media. Participants were asked to rate the inferential power of different research designs and of mock results that varied in the degree to which they supported different ideologies. Results were suggestive that researchers harbor sincere differences of opinion concerning the inferential value of relevant research. There was no suggestion that ideological confirmation biases drive these differences. However, challenges associated with recruiting a large enough sample of experts as well as identifying believable mock scenarios limit the study's inferential scope.

    Robust T cell function recovery has been shown to be crucial in determining allogeneic hematopoietic stem cell transplantation (HSCT) outcome, and there is growing evidence that the thymus plays a central role in regulating this process. We performed a long-term analysis of the role of thymic activity recovery in a population of pediatric patients undergoing allogeneic HSCT by signal joint T cell receptor excision circle (sjTREC) quantification. In this study, characterized by a long-term follow-up (median, 72 months), we found patients with higher levels of sjTRECs before transplantation had a statistically significant reduced risk of death compared with patients with lower values (relative risk, .31; 95% confidence interval, .30 to .32; P = .02), showing this different outcome was mainly related to a reduction of relapse incidence (14% versus 43%, P = .02). Unlike previous reports, we observed no correlation between sjTREC levels and lymphocyte recovery. Moreover, we confirmed that only graft-versus-host disease influenced thymic activity after transplantation. In conclusion, our results suggest an association between pretransplantation thymic activity and the long-term outcome of pediatric patients undergoing HSCT, mainly through a reduction of relapse opportunities.

    The author presents an attempt of using ultrasonographic technique in diagnosis, planning and observation of treatment results of temporo-mandibular joint pain dysfunctions. Temporo-mandibular joint pain dysfunctions are interchangeably also called temporo-mandibular joint functional disorders. The assessment of pain symptoms in temporo-mandibular joint dysfunctions pain symptoms is principally based on a subjective estimation by the examining practitioner. There is no univocal definition of the disease or a simple index evidencing important symptoms in decision making. Additionally X-ray technique examinations, being hitherto used, in early stages of the disorder do not allow to diagnose it, and are also burdensome to a patient. The aim of this study was to confirm visibility of anatomical elements of the temporo-mandibular joint in an ultrasound examination, assess the mobility of the articular disc before, during and after prosthetic treatment with and without the use of ultrasound technique, and to determine the period of time necessary to obtain a therapeutic effect. The study material consisted of 180 patients, 128 women and 52 men, aged 20 to 60 years, treated by applying prostheses because of temporo-mandibular joint pain dysfunction, in the Department of Prosthetic Dentistry of the Pomeranian Medical Academy. The patients were divided into 2 groups, control and study group. The control group consisted of 90 patients, 63 women and 27 men. In this group prosthetic treatment planning and observation of results was based on a subjective estimation of the practitioner. The study group here comprised 90 patients, 65 women and 25 men, aged 26 to 60 years.

    To compare visual acuity outcomes, vision-related quality of life, and complications related to cataract surgery in eyes with and without glaucoma. Retrospective cohort study. Cataract surgery outcomes in cases with and without glaucoma from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project were compared. We identified 608 glaucoma cases and 4306 controls undergoing planned cataract surgery alone. After adjusting for age, pseudoexfoliation, small pupil, prior ocular surgery, and anterior chamber depth, we found that glaucoma cases were more likely to have posterior capsular tear with vitrectomy (odds ratio [OR] 1.8, P = .03) and sulcus intraocular lens placement (OR 1.65, P = .03) during cataract surgery. Glaucoma cases were more likely to have postoperative inflammation (OR 1.73, P < .0001), prolonged elevated intraocular pressure (OR 2.96, P = .0003), and additional surgery within 30 days (OR 1.92, P = .03). Mean best-corrected visual acuity (BCVA) and Visual Function Questionnaire (VFQ) scores significantly improved after cataract surgery in both groups (P < .0001), but there were larger improvements in BCVA (P = .01) and VFQ composite scores (P < .0001) in the nonglaucoma vs the glaucoma group. A total of 3621 nonglaucoma cases (94.1%) had postoperative BCVA 20/40 or better, compared to 466 glaucoma cases (89.6%) (P = .0003). Eyes with glaucoma are at increased risk for complications and have more modest visual outcomes after cataract surgery compared to eyes without glaucoma. Despite this, glaucoma patients still experience significant improvement in vision-related outcomes after cataract extraction. Further study is needed to explore potential factors that influence cataract surgery outcomes in glaucomatous eyes. Published by Elsevier Inc.

    The Sibutramine Cardiovascular OUTcomes trial showed that sibutramine produced greater mean weight loss than placebo but increased cardiovascular morbidity but not mortality. The relationship between 12-month weight loss and subsequent cardiovascular outcomes is explored. Overweight/obese subjects (N = 10 744), ≥55 years with cardiovascular disease and/or type 2 diabetes mellitus, received sibutramine plus weight management during a 6-week Lead-in Period before randomization to continue sibutramine (N = 4906) or to receive placebo (N = 4898). The primary endpoint was the time from randomization to first occurrence of a primary outcome event (non-fatal myocardial infarction, non-fatal stroke, resuscitated cardiac arrest or cardiovascular death). For the total population, mean weight change during Lead-in Period (sibutramine) was -2.54 kg. Post-randomization, mean total weight change to Month 12 was -4.18 kg (sibutramine) or -1.87 kg (placebo). Degree of weight loss during Lead-in Period or through Month 12 was associated with a progressive reduction in risk for the total population in primary outcome events and cardiovascular mortality over the 5-year assessment. Although more events occurred in the randomized sibutramine group, on an average, a modest weight loss of approximately 3 kg achieved in the Lead-in Period appeared to offset this increased event rate. Moderate weight loss (3-10 kg) reduced cardiovascular deaths in those with severe, moderate or mild cardiovascular disease. Modest weight loss over short-term (6 weeks) and longer-term (6-12 months) periods is associated with reduction in subsequent cardiovascular mortality for the following 4-5 years even in those with pre-existing cardiovascular disease. While the sibutramine group experienced more primary outcome events than the placebo group, greater weight loss reduced overall risk of these occurring in both groups. © 2011 Blackwell Publishing Ltd.

    We aimed to evaluate whether potential changes in the patient's illness perception can significantly influence short-term seizure burden following video-electroencephalography (EEG) confirmation/explanation of psychogenic nonepileptic seizures (PNES). Patients with PNES were dichotomized to two groups based on a five-point Symptom Attribution Scale: (a) those who prior to diagnosis perceived their seizures to be solely ("5") or mainly ("4") physical in origin (physical group) and (b) the remainder of patients with PNES (psychological group). The physical group (n=32), psychological group (n=40), and group with epilepsy (n=26) also completed the Brief Illness Perception Questionnaire (BIPQ) prior to diagnosis, and were followed up at 3months as well as at 6months postdiagnosis. At 3months postdiagnosis, the physical group experienced significantly greater improvement in seizure intensity (p=0.002) and seizure frequency (p=0.016) when compared with the psychological group. The physical group was significantly more likely to have modified their symptom attribution toward a greater psychological role to their seizures (p=0.002), and their endorsement on the BIPQ item addressing "consequences" (How much do your seizures affect your life?) was significantly less severe (p'=0.014) when compared with that of the psychological group and the group with epilepsy. At 6months postdiagnosis, the physical group continued to experience significantly greater improvement in seizure intensity (p=0.007) while their seizure frequency no longer reached significant difference (p=0.078) when compared with the psychological group. The physical group continued to be significantly more likely to have modified their symptom attribution toward a greater psychological role to their seizures (p=0.005), and their endorsement on the BIPQ item addressing "consequences" remained significantly less severe (p'=0.037) when compared with the psychological group and the group with epilepsy.

    Full Text Available Background. Appropriate critical care admissions are an important component of surgical care. However, there are few data describing postoperative critical care admission in resource-limited low- and middle-income countries. Objective. To describe the demographics, organ failures, organ support and outcomes of non-cardiac surgical patients admitted to critical care units in South Africa (SA. Methods. The SA Surgical Outcomes Study (SASOS was a 7-day national, multicentre, prospective, observational cohort study of all patients ≥16 years of age undergoing inpatient non-cardiac surgery between 19 and 26 May 2014 at 50 government-funded hospitals. All patients admitted to critical care units during this study were included for analysis. Results. Of the 3 927 SASOS patients, 255 (6.5% were admitted to critical care units; of these admissions, 144 (56.5% were planned, and 111 (43.5% unplanned. The incidence of confirmed or strongly suspected infection at the time of admission was 35.4%, with a significantly higher incidence in unplanned admissions (49.1 v. 24.8%, p<0.001. Unplanned admission cases were more frequently hypovolaemic, had septic shock, and required significantly more inotropic, ventilatory and renal support in the first 48 hours after admission. Overall mortality was 22.4%, with unplanned admissions having a significantly longer critical care length of stay and overall mortality (33.3 v. 13.9%, p<0.001. Conclusion. The outcome of patients admitted to public sector critical care units in SA is strongly associated with unplanned admissions. Adequate ‘high care-dependency units’ for postoperative care of elective surgical patients could potentially decrease the burden on critical care resources in SA by 23%. This study was registered on ClinicalTrials.gov (NCT02141867.

    The Food and Drug Administration's Sentinel System developed parameterized, reusable analytic programs for evaluation of medical product safety. Research on outpatient antibiotic exposures, and Clostridium difficile infection (CDI) with non-user reference groups led us to expect a higher rate of CDI among outpatient clindamycin users vs penicillin users. We evaluated the ability of the Cohort Identification and Descriptive Analysis and Propensity Score Matching tools to identify a higher rate of CDI among clindamycin users. We matched new users of outpatient dispensings of oral clindamycin or penicillin from 13 Data Partners 1:1 on propensity score and followed them for up to 60 days for development of CDI. We used Cox proportional hazards regression stratified by Data Partner and matched pair to compare CDI incidence. Propensity score models at 3 Data Partners had convergence warnings and a limited range of predicted values. We excluded these Data Partners despite adequate covariate balance after matching. From the 10 Data Partners where these models converged without warnings, we identified 807 919 new clindamycin users and 8 815 441 new penicillin users eligible for the analysis. The stratified analysis of 807 769 matched pairs included 840 events among clindamycin users and 290 among penicillin users (hazard ratio 2.90, 95% confidence interval 2.53, 3.31). This evaluation produced an expected result and identified several potential enhancements to the Propensity Score Matching tool. This study has important limitations. CDI risk may have been related to factors other than the inherent properties of the drugs, such as duration of use or subsequent exposures. Copyright © 2018 John Wiley & Sons, Ltd.

    Clinical data are largely focused on depressive comorbidity in OCD. However in practice, treating resistant or severe OCD sufferers revealed many cases who seem to have an authentic OCD with a hidden comorbid bipolar disorder. Most reports had evaluated the OCD comorbidity in unipolar and bipolar mood disorders (Kruger et al., 1995; Chen et Dilsaver, 1995). The only investigation in clinical population focused on the reverse issue was conducted in Pisa. Perugi et al. (1997) have showed in a consecutive series of 315 OCD outpatients, that 15.7% presented a bipolar comorbidity, mostly with BP-II disorder. Further analyses suggested that when comorbidity occurs with bipolar and unipolar depression, it has a differential impact on the clinical picture and course of OCD. The rate of bipolar comorbidity in OCD was analyzed in a recent epidemiological survey undertaken by the French Association of patients suffering from OCD (FA-OCD or AFTOC in French). In a sample of 453 OCD patients, 76% had suffered from a major depression, 11% from bipolar disorder (DSM IV mania or hypomania), 30% from hypomania (cases that obtained a score > or = 10 on the self-rated Angst Hypomania Checklist). According to the score > or = 10 on Self-rated Questionnaire for Cyclothymic Temperament, 50% were classified as cyclothymic. The self-assessment of soft-bipolar dimensions, such as hypomania and cyclothymia was previously validated in a multi-site study in major depression (Hantouche et al., 1998). Further analyses showed that comorbidity with soft bipolarity was characterized by significant interactions with high levels of impulsivity, anger attacks and suicidal behavior. In order to confirm these data, another cohort (n = 175 patients treated by psychiatrists for OCD) was formed and named "PSY-OCD". Comparative analyses between the two populations allowed showing very few demographic and clinical differences. The frequency rate of "bipolar OCD" was equivalent in both populations: BP

    To assess challenges to implementation of a new National Healthcare Safety Network (NHSN) surveillance definition, mucosal barrier injury laboratory-confirmed bloodstream infection (MBI-LCBI). Multicenter field test. Selected locations of acute care hospitals participating in NHSN central line-associated bloodstream infection (CLABSI) surveillance. Hospital staff augmented their CLABSI surveillance for 2 months to incorporate MBI-LCBI: a primary bloodstream infection due to a selected group of organisms in patients with either neutropenia or an allogeneic hematopoietic stem cell transplant with gastrointestinal graft-versus-host disease or diarrhea. Centers for Disease Control and Prevention (CDC) staff reviewed submitted data to verify whether CLABSIs met MBI-LCBI criteria and summarized the descriptive epidemiology of cases reported. Eight cancer, 2 pediatric, and 28 general acute care hospitals including 193 inpatient units (49% oncology/bone marrow transplant [BMT], 21% adult ward, 20% adult critical care, 6% pediatric, 4% step-down) conducted field testing. Among 906 positive blood cultures reviewed, 282 CLABSIs were identified. Of the 103 CLABSIs that also met MBI-LCBI criteria, 100 (97%) were reported from oncology/BMT locations. Agreement between hospital staff and CDC classification of reported CLABSIs as meeting the MBI-LCBI definition was high (90%; κ = 0.82). Most MBI-LCBIs (91%) occurred in patients meeting neutropenia criteria. Some hospitals indicated that their laboratories' methods of reporting cell counts prevented application of neutropenia criteria; revised neutropenia criteria were created using data from field testing. Hospital staff applied the MBI-LCBI definition accurately. Field testing informed modifications for the January 2013 implementation of MBI-LCBI in the NHSN.

    The optimal algorithm for serological syphilis screening is still a matter of debate. We have previously evaluated the performance of the Bioelisa Syphilis 3.0, using a selection of archived sera, and in this study compare these results with the Bioelisa results after clinical implementation. All Bioelisa Syphilis 3.0 results obtained since clinical implementation were analyzed. Bioelisa-positive or borderline samples were retested using Treponema pallidum particle agglutination, rapid plasma reagin test, fluorescent treponemal antibody-absorption test, and/or immunoblot. On sera sent in together with cerebrospinal fluid, occasionally both the T. pallidum particle agglutination and Bioelisa were performed. The Bioelisa was performed on 14,622 sera. Bioelisa-positive samples, which were not retested by the previously described assays, were withdrawn from the database (n = 36). In 1.3% of the samples (187/14,586), the Bioelisa was positive or borderline and, ultimately, 115 sera were considered true positive (prevalence 0.8%). The specificity of the Bioelisa was 99.5%. Based on the results of all performed diagnostic assays, the specificity of the Bioelisa of 99.5% is very consistent with that found in the initial study (100%; 95% confidence interval was 98.0%-100%). Interpreting (positive) test results is difficult in the absence of a gold standard, especially when the disease prevalence is low. Results should be viewed in the light of the patients' characteristics.

    2000-01-01

    As described, the purpose of the Performance Confirmation Plan is to specify monitoring, testing, and analysis activities for evaluating the accuracy and adequacy of the information used to determine that performance objectives for postclosure will be met. This plan defines a number of specific performance confirmation activities and associated test concepts in support of the MGR that will be implemented to fulfill this purpose. In doing so, the plan defines an approach to identify key factors and processes, predict performance, establish tolerances and test criteria, collect data (through monitoring, testing, and experiments), analyze these data, and recommend appropriate action. The process of defining which factors to address under performance confirmation incorporates input from several areas. In all cases, key performance confirmation factors are those factors which are: (1) important to safety, (2) measurable and predictable, and (3) relevant to the program (i.e., a factor that is affected by construction, emplacement, or is a time-dependent variable). For the present version of the plan, performance confirmation factors important to safety are identified using the principal factors from the RSS (CRWMS M and O 2000a) (which is derived from TSPA analyses) together with other available performance assessment analyses. With this basis, key performance confirmation factors have been identified, and test concepts and test descriptions have been developed in the plan. Other activities are also incorporated into the performance confirmation program outside of these key factors. Additional activities and tests have been incorporated when they are prescribed by requirements and regulations or are necessary to address data needs and model validation requirements relevant to postclosure safety. These other activities have been included with identified factors to construct the overall performance confirmation program

    Obtaining reliable cultures during revision arthroplasty is important to adequately diagnose and treat a prosthetic joint infection (PJI). The influence of antimicrobial prophylaxis on culture results remains unclear. Since withholding prophylaxis increases the risk for surgical site infections, clarification on this topic is critical. A systematic review was performed with the following research question: in patients who undergo revision surgery of a prosthetic joint, does preoperative antimicrobial prophylaxis affect the culture yield of intraoperative samples in comparison with nonpreoperative antimicrobial prophylaxis? Seven articles were included in the final analysis. In most studies, standard diagnostic culture techniques were used. In patients with a PJI, pooled analysis showed a culture yield of 88% (145/165) in the prophylaxis group versus 95% (344/362) in the nonprophylaxis group ( P = 0.004). Subanalysis of patients with chronic PJIs showed positive cultures in 88% (78/89) versus 91% (52/57), respectively ( P = 0.59). In patients with a suspected chronic infection, a maximum difference of 4% in culture yield between the prophylaxis and nonprophylaxis groups was observed. With the use of standard culture techniques, antimicrobial prophylaxis seems to affect cultures in a minority of patients. Along with the known risk of surgical site infections due to inadequate timing of antimicrobial prophylaxis, we discourage the postponement of prophylaxis until tissue samples are obtained in revision surgery. Future studies are necessary to conclude whether the small percentage of false-negative cultures after prophylaxis can be further reduced with the use of more-sensitive culture techniques, like sonication.

    2014-01-01

    Background Intimate partner violence (IPV) has been known to adversely affect the mental health of victims. Research has tended to focus on the mental health impact of physical violence rather than considering other forms of violence. Objective To systematically review the literature in order to identify the impact of all types of IPV victimisation on various mental health outcomes. Method A systematic review of 11 electronic databases (2004–2014) was conducted. Fifty eight papers were identified and later described and reviewed in relation to the main objective. Results Main findings suggest that IPV can have increasing adverse effects on the mental health of victims in comparison with those who have never experienced IPV or those experiencing other traumatic events. The most significant outcomes were associations between IPV experiences with depression, posttraumatic stress disorder, and anxiety. Findings confirm previous observations that the severity and extent of IPV exposure can increase mental health symptoms. The effect of psychological violence on mental health is more prominent than originally thought. Individual differences such as gender and childhood experience of violence also increase IPV risk and affect mental health outcomes in diverse ways. Conclusions Psychological violence should be considered as a more serious form of IPV which can affect the mental health of victims. Experiencing more than one form of IPV can increase severity of outcomes. Researchers should look at IPV as a multi-dimensional experience. A uniformed definition and measure of IPV could help advance knowledge and understanding of this disparaging global issue. PMID:25279103

    Science.gov (United States)

    In late February, two separate observations confirmed the 1978 discovery by U.S. Naval Observatory scientist James W. Christy of a moon orbiting the planet Pluto. According to the U.S. Naval Observatory, these two observations were needed before the International Astronomical Society (IAS) would officially recognize the discovery.Two types of observations of the moon, which was named Charon after the ferryman in Greek mythology who carried the dead to Pluto's realm, were needed for confirmation: a transit, in which the moon passes in front of Pluto, and an occultation, in which the moon passes behind the planet. These two phenomena occur only during an 8-year period every 124 years that had been calculated to take place during 1984-1985. Both events were observed in late February.

    2013-11-01

    Full Text Available Behavioral studies demonstrate that the timing of receiving gains or losses affects decision-making, a phenomenon known as temporal discounting, as participants are inclined to prefer immediate rewards over delayed ones and vice versa for losses. The present study used the event-related potential (ERP technique with a simple gambling task to investigate how delayed rewards and losses affected the brain activity in outcome evaluations made by 20 young adults. Statistical analysis revealed a larger feedback related negativity (FRN effect between loss and gain following immediate outcomes than following future outcomes. In addition, delay impacted FRN only in gain conditions, with delayed winning eliciting a more negative FRN than immediatewinning. These results suggest that temporal discounting and sign effect could be encoded in the FRN in the early stage of outcome evaluation.

    Phosphine (PH{sub 3}) was tentatively identified a few years ago in the carbon star envelopes IRC +10216 and CRL 2688 from observations of an emission line at 266.9 GHz attributable to the J = 1-0 rotational transition. We report the detection of the J = 2-1 rotational transition of PH{sub 3} in IRC +10216 using the HIFI instrument on board Herschel, which definitively confirms the identification of PH{sub 3}. Radiative transfer calculations indicate that infrared pumping in excited vibrational states plays an important role in the excitation of PH{sub 3} in the envelope of IRC +10216, and that the observed lines are consistent with phosphine being formed anywhere between the star and 100 R {sub *} from the star, with an abundance of 10{sup –8} relative to H{sub 2}. The detection of PH{sub 3} challenges chemical models, none of which offer a satisfactory formation scenario. Although PH{sub 3} holds just 2% of the total available phosphorus in IRC +10216, it is, together with HCP, one of the major gas phase carriers of phosphorus in the inner circumstellar layers, suggesting that it could also be an important phosphorus species in other astronomical environments. This is the first unambiguous detection of PH{sub 3} outside the solar system, and is a further step toward a better understanding of the chemistry of phosphorus in space.

    This longitudinal study describes women’s media use during their first year of college and examines associations between media use and academic outcomes. Female students (N = 483, Mage = 18.1 years) reported on their use of 11 media forms and their grade point average, academic behaviors, academic confidence, and problems affecting schoolwork. Allowing for multi-tasking, women reported nearly 12 hours of media use per day; use of texting, music, the Internet, and social networking was heaviest. In general, media use was negatively associated with academic outcomes after controlling for prior academics and demographics. Exceptions were newspaper reading and music listening, which were positively associated with academic outcomes. There were significant indirect effects of magazine reading and social networking on GPA via academic behaviors, confidence, and problems. Results show that female college students are heavy users of new media, and that some forms of media use may adversely impact academic performance. PMID:24505554

    The ASSESS Neutralization module (Neutralization) is part of the Analytic System and Software for Evaluation of Safeguards and Security (ASSESS), a vulnerability assessment tool. Neutralization models a fire fight between security inspectors (SIs) and adversaries. This paper reports that a comparison has been made between actual outcomes of police and small military engagements and the results predicted by the Neutralization module for similar scenarios. The results of this comparison show a surprising correlation between predicted outcomes (based on numbers of combatants, weapon types, and exposures, etc.) and the actual outcomes of the engagements analyzed. The importance of this analysis is that given the defenders have intelligence on actual adversary characteristics or are protecting against a design basis threat, defense capabilities can be evaluated before an engagement. Results could then be used to develop a favorable probability of a desired outcome. For example, law enforcement agencies are frequently able to compile the number of criminals, types of weaponry, willingness to use force, etc., from analysis of crime scenes

    In 1987 the European Muon Collaboration (EMC - June 1988, page 9) reported results from a polarized muon-proton scattering experiment at CERN which puzzled the particle and nuclear physics communities. Contrary to the prediction of the naive quark model, the EMC found that little of the proton spin seemed to be carried by the spins of the quarks. An extensive experimental programme was therefore immediately proposed at CERN, SLAC (Stanford) and DESY (Hamburg) to measure the spin structure function of the neutron and to repeat the proton measurement with improved accuracy

    Full Text Available Objectives. This study assessed the correlation between performance intelligence and the postoperative cochlear implant (CI outcome in Korean-speaking children. In addition, the relationship between the performance intelligence subscales and the post-CI speech outcome was evaluated. Materials and Methods. Thirteen pediatric CI users (five males, eight females; median age at implantation 6.2 (range 1.3–14.2 years; median age at intelligence test 9.3 (range 5–16 years who were tested using the Korean Educational Development Institute-Wechsler Intelligence Scale for children were studied. The correlations between the intelligence scores and 1-2 years postoperative Categories of Auditory Performance (CAP scores and between subscales of performance and 1-2 years postoperative CAP scores were analyzed. Results. There was no correlation between the categories of verbal intelligence quotient (IQ and performance IQ for “mentally retarded” and “average,” respectively (Spearman’s rho = 0.42, P=0.15. There was a strong correlation between performance IQ and the postoperative CAP scale (Spearman’s rho = 0.8977, P=0.0008. “Picture arrangement” and “picture completion,” reflecting social cognition, were strongly correlated with the postoperative CAP scales. Conclusion. Performance intelligence, especially social cognition, was strongly related to the postoperative CI outcome of cochlear implant users. Therefore, auditory rehabilitation, including social rehabilitation, should maximize the postoperative CI outcomes.

    Prospective analysis. Our objective was to analyze clinical and functional results of patients with spondylolysis treated via direct intralaminar screw fixation and autograft, a minimally invasive and motion-preserving surgery. Spondylolysis is usually treated nonoperatively; multiple surgical techniques are available when nonoperative measures fail. No studies evaluate the clinical and functional outcomes and their correlation with pars defect size and disc morphology on magnetic resonance imaging. We reviewed patients with spondylolysis treated with intralaminar screw fixation and bone grafting from 2000 through 2010. Of the 31 patients (mean age, 16 yr; range, 10-37 yr), 25 (81%) were competitive athletes. Preoperative computed tomographic scans were used to measure the pars defect size, and preoperative magnetic resonance images were graded using Pfirrmann classification for correlation with postoperative outcomes. Student t test was used for analysis (significance, P spondylolysis repair for persistent pain starting 18 months after intralaminar screw fixation, 2 patients sustained unilateral intralaminar screw fractures at L5, and 1 patient required irrigation and debridement for a superficial postoperative infection. There was no correlation among preoperative magnetic resonance imaging disc morphology, defect size on computed tomography, patient age, and clinical outcomes. Direct repair of spondylolysis with intralaminar screws offers a low profile, reliable treatment with good functional outcome and a low complication rate in active patients. 4.

    OBJECTIVE While most paraclinoid aneurysms can be clipped with excellent results, new postoperative visual deficits are a concern. New technology, including flow diverters, has increased the popularity of endovascular therapy. However, endovascular treatment of paraclinoid aneurysms is not without procedural risks, is associated with higher rates of incomplete aneurysm occlusion and recurrence, and may not address optic nerve compression symptoms that surgical debulking can. The increasing endovascular management of paraclinoid aneurysms should be justified by comparisons to surgical benchmarks. The authors, therefore, undertook this study to define patient, visual, and aneurysm outcomes in the most common type of paraclinoid aneurysm: ophthalmic artery (OphA) aneurysms. METHODS Results from microsurgical clipping of 208 OphA aneurysms in 198 patients were retrospectively reviewed. Patient demographics, aneurysm morphology (size, calcification, etc.), clinical characteristics, and patient outcomes were recorded and analyzed. RESULTS Despite 20% of these aneurysms being large or giant in size, complete aneurysm occlusion was accomplished in 91% of 208 cases, with OphA patency preserved in 99.5%. The aneurysm recurrence rate was 3.1% and the retreatment rate was 0%. Good outcomes (modified Rankin Scale score 0-2) were observed in 96.2% of patients overall and in all 156 patients with unruptured aneurysms. New visual field defects (hemianopsia or quadrantanopsia) were observed in 8 patients (3.8%), decreased visual acuity in 5 (2.4%), and monocular blindness in 9 (4.3%). Vision improved in 9 (52.9%) of the 17 patients with preoperative visual deficits. CONCLUSIONS The most important risk associated with clipping OphA aneurysms is a new visual deficit. Meticulous microsurgical technique is necessary during anterior clinoidectomy, aneurysm dissection, and clip application to optimize visual outcomes, and aggressive medical management postoperatively might potentially

    Employee Assistance Programs (EAPs) are widely used to help employees experiencing personal or work-related difficulties that impact work productivity. However, rigorous research on the effectiveness of programs to improve work-related outcomes is lacking. The current study represents a major advance in EAP research by using a prospective, quasi-experimental design with a large and diverse employee base. Using propensity scores calculated from demographic, social, work-related, and psychological variables collected on baseline surveys, we matched 156 employees receiving EAP to 188 non-EAP employees. Follow-up surveys were collected from 2 to 12 months post-baseline (M = 6.0). At follow-up, EAP employees had significantly greater reductions in absenteeism (b = -.596, p = .001) and presenteeism (b = -.217, p = .038), but not workplace distress (b = -.079, p = .448), than did non-EAP employees. Tests of moderation of baseline alcohol use, depression, anxiety, and productivity indicate that for the most part, the program works equally well for all groups. However, EAP did more to reduce absenteeism for those who began with lower severity of depression and anxiety at baseline. Results provide the scientific rigor needed to demonstrate EAP impact on improved work outcomes. In the first study of its kind, findings confirm the value of EAPs to help employees address personal and work-related concerns that are affecting job performance.

    Perforation during colonoscopy is a rare but severe complication. The aim of this study was to assess the time management and laparoscopic therapy of this complication and to evaluate patient outcomes. A retrospective analysis was done on 15 patients operated for a perforation from colonoscopy between January 2000 and December 2006. Three perforations occurred during diagnostic and 12 perforations during interventional colonoscopy. Two perforations occurred as transmural thermal injury to the colon wall. Peritonitis was found in 4 cases and significantly correlated with the mean time between perforation and operation. Twelve perforations were oversewn laparoscopically and 3 perforations were oversewn by laparotomy. After laparoscopic treatment, hospital stay was significantly shorter than after laparotomy. One patient had a postoperative wound infection, mortality was 0%. Laparoscopic oversewing is a safe and effective method in the treatment of perforation from colonoscopy. Optimizing the time range between perforation and laparoscopic therapy results in a better outcome for the patients.

    Objectives: Revision anterior cruciate ligament (ACL) reconstruction is associated with poorer outcomes and higher rerupture rates when compared to primary ACL reconstruction. There is also a significant heterogeneity in surgical technique, number of stages, and graft options. We report a large single surgeon case series with hamstring autograft as a graft option. Methods: Observational series of revision ACL reconstructions performed by the senior author between 2005 and 2015 was carried out. Chart reviews and clinic follow-ups were performed with the following recorded – re-rupture rate, radiographic grading of osteoarthritis, KT-1000 arthrometer test, IKDC outcome scores and knee range of motion. All patients underwent single bundle four-strand hamstring autograft performed in one stage with use of new tunnels in majority of the cases. Results: 66 patients underwent hamstring autograft one-stage revision ACL reconstruction by Dr Jens Buelow. Chart review was carried out on all patients, and 26 (39%) were followed up in clinic and/or by phone with a mean follow up of 4.7 years. Outcomes included re-rupture rate of 4.5%, reoperation rate of 12%, mean visual analogue scale score of 7.6, mean side-to-side difference of 2.6 mm for KT-1000 arthrometer test, and mean IKDC score of 79. Of the 17 patients with radiographs, 40% had moderate osteoarthritis (grade 2 or 3) at follow-up. Conclusion: Revision ACL reconstruction can result in a satisfactory outcome when performed with a hamstring autograft in one stage.

    Background Although BRCA1/2 genetic testing is discouraged in minors, mothers may disclose their own results to their children. Factors affecting patients’ disclosure decisions and patient outcomes of disclosure are largely unknown. Methods Mothers (N = 221) of children ages 8-21 enrolled in this prospective study of family communication about cancer genetic testing. Patients underwent BRCA1/2 genetic counseling and testing, and completed standardized behavioral assessments prior to and 1-month following receipt of their results. Results Most patients (62.4%) disclosed BRCA1/2 test results to their child. Patients were more likely to disclose if they received negative or uninformative vs. positive results (OR = 3.11; 95% CI = 1.11 - 8.71; P = .03), their child was ≥ 13 years of age vs. younger (OR = 5.43; 95% CI = 2.18 - 13.53; P Post-decision satisfaction about disclosure was lowest among nondisclosing patients (P information is perceived as beneficial. Satisfaction with disclosure decision-making remains lowest among nondisclosing and conflicted patients. Family communication decision support adjuncts to genetic counseling are needed to help ameliorate these effects. Impact This study describes the prevalence of family communication about maternal BRCA1/2 genetic testing with minor children, and decisions and outcomes of disclosure. PMID:23825307

    Full Text Available BACKGROUND: Nigeria is faced with a high burden of Human Immunodeficiency Virus (HIV infection and multidrug-resistant tuberculosis (MDR-TB. Treatment outcomes among MDR-TB patients registered across the globe have been poor, partly due to high loss-to-follow-up. To address this challenge, MDR-TB patients in Nigeria are hospitalized during the intensive-phase(IP of treatment (first 6-8 months and are provided with a package of care including standardized MDR-TB treatment regimen, antiretroviral therapy (ART and cotrimoxazole prophylaxis (CPT for HIV-infected patients, nutritional and psychosocial support. In this study, we report the end-IP treatment outcomes among them. METHODS: In this retrospective cohort study, we reviewed the patient records of all bacteriologically-confirmed MDR-TB patients admitted for treatment between July 2010 and October 2012. RESULTS: Of 162 patients, 105(65% were male, median age was 34 years and 28(17% were HIV-infected; all 28 received ART and CPT. Overall, 138(85% were alive and culture negative at the end of IP, 24(15% died and there was no loss-to-follow-up. Mortality was related to low CD4-counts at baseline among HIV-positive patients. The median increase in body mass index among those documented to be underweight was 2.6 kg/m2 (p<0.01 and CD4-counts improved by a median of 52 cells/microL among the HIV-infected patients (p<0.01. CONCLUSIONS: End-IP treatment outcomes were exceptional compared to previously published data from international cohorts, thus confirming the usefulness of a hospitalized model of care. However, less than five percent of all estimated 3600 MDR-TB patients in Nigeria were initiated on treatment during the study period. Given the expected scale-up of MDR-TB care, the hospitalized model is challenging to sustain and the national TB programme is contemplating to move to ambulatory care. Hence, we recommend using both ambulatory and hospitalized approaches, with the latter being reserved

    To ascertain the number of cases of spontaneous (aneurysmal) subarachnoid haemorrhage presenting to Tan Tock Seng Hospital, Singapore, over a one year period, the demographics of the patients involved, their treatment and their eventual outcome. A retrospective study from June 1995 to June 1996. There were 62 patients admitted over this period with an average of 5 patients per month. Their ages ranged from 9 to 85 years with a mean of 54 years. All 62 patients underwent 4-vessel cerebral angiograms. Forty-three patients (69%) underwent clipping of their aneurysms. Twelve patients (19%) had negative angiograms. Four patients (6%) underwent coiling of their aneurysms via interventional neuroradiology techniques. Patients with subarachnoid haemorrhage of Grades 1 to 3 on the WFNS (World Federation of Neurological Surgeons) grading had a favourable outcome (Glasgow Outcome Score of 4 and 5) in 85% of the cases. The overall mortality rate for the operated group (all grades) was 11%. However for the group with good WFNS grading, namely the Grade 1 to 2 groups, there were no deaths. Twenty-four percent of patients developed clinically symptomatic vasospasm. Eighteen percent of patients required ventriculo-peritoneal shunting for hydrocephalus secondary to the subarachnoid haemorrhage. The overall management mortality (operated and non-operated cases) was 14% for proven aneurysmal and angiographically-negative spontaneous subarachnoid haemorrhage. These results are comparable to that of other reputable centers reported in the literature.

    Community-based strategies that foster frequent contact between caregivers of children under five and provide credible sources of health information are essential to improve child survival. Care Groups are a community-based implementation strategy for the delivery of social and behavior change interventions. This study assessed if supervision of Care Group activities by Ministry of Health (MOH) personnel could achieve the same child health outcomes as supervision provided by specialized non-governmental organization (NGO) staff. The study was a pretest-posttest quasi-experimental design implemented in Burundi. A total of 45 MOH-led Care Groups with 478 Care Group Volunteers (CGVs) were established in the intervention area; and 50 NGO-led Care Groups with 509 CGVs were formed in the comparison area. Data were collected from 593 and 700 mothers of children 0-23 months at baseline and endline, respectively. Pearson's chi-squared test and difference-in-difference analysis assessed changes in 40 child health and nutrition outcomes. A qualitative process evaluation was also conducted midway through the study. The MOH-led Care Group model performed at least as well as the NGO-led model in achieving specific child health and nutrition outcomes. Mothers of children 0-23 months in the intervention and comparison sites reported similar levels of knowledge and practices for 38 of 40 dependent variables measured in the study, and these results remained unchanged after accounting for differences in the indicator values at baseline. Process monitoring data confirmed that the MOH-led Care Group model and the NGO-led Care Group model were implemented with similar intervention strength. The study demonstrated that behavior change interventions traditionally led by NGOs can be implemented through the existing MOH systems and achieve similar results, thereby increasing the potential for sustainable child health outcomes. Future research on the MOH-led Care Group model is required to

    2017-04-01

    Full Text Available Continuous assessment aims to enhance student learning and understanding of a subject and so achieve better educational outcomes. We investigated how continuous assessment grades affected final exam grades. Using a dataset for six academic post-Bologna Process years (2009-2015 for a first-year undergraduate microeconomics course offered at a Spanish public university, we examined conditional dependence between continuous assessment and final exam grades. Our results would indicate a limited contribution of continuous assessment results to final exam results: the probability of the final exam performance improving on the continuous assessment grade was lower than the probability of the opposite occurring. A consistent exception, however, was students who obtained an A grade for continuous assessment. Our results would cast some doubt on the beneficial effects of continuous assessment advocated by the Bologna Process.

    Surrogacy is a highly debated method mainly used for treating women with infertility caused by uterine factors. This systematic review summarizes current levels of knowledge of the obstetric, medical and psychological outcomes for the surrogate mothers, the intended parents and children born as a result of surrogacy. PubMed, Cochrane and Embase databases up to February 2015 were searched. Cohort studies and case series were included. Original studies published in English and the Scandinavian languages were included. In case of double publications, the latest study was included. Abstracts only and case reports were excluded. Studies with a control group and case series (more than three cases) were included. Cohort studies, but not case series, were assessed for methodological quality, in terms of risk of bias. We examined a variety of main outcomes for the surrogate mothers, children and intended mothers, including obstetric outcome, relationship between surrogate mother and intended couple, surrogate's experiences after relinquishing the child, preterm birth, low birthweight, birth defects, perinatal mortality, child psychological development, parent-child relationship, and disclosure to the child. The search returned 1795 articles of which 55 met the inclusion criteria. The medical outcome for the children was satisfactory and comparable to previous results for children conceived after fresh IVF and oocyte donation. The rate of multiple pregnancies was 2.6-75.0%. Preterm birth rate in singletons varied between 0 and 11.5% and low birthweight occurred in between 0 and 11.1% of cases. At the age of 10 years there were no major psychological differences between children born after surrogacy and children born after other types of assisted reproductive technology (ART) or after natural conception. The obstetric outcomes for the surrogate mothers were mainly reported from case series. Hypertensive disorders in pregnancy were reported in between 3.2 and 10% of cases and

    Tuberculosis in children and adults is a growing problem with important public health implications. In Latvia the incidence of tuberculosis (TB) in children up to age 14 has increased from 7,1 per 100000 in 1992 to 28,8 per 100000 in 2003. The diagnosis of TB is confirmed by isolation and identification of M. tuberculosis (MT) from clinical specimen. Confirmation of the disease, however, is difficult in children due to poor bacilli excretion and even under the best circumstances only about 30-40% of pediatric TB cases are proved bacteriologically. Of the 370 pediatric TB cases diagnosed between January 1, 2001 and December 1, 2003 in Latvia, 53 (14,3%) were confirmed bacteriologically. The clinical, radiological, immunological and anamnestic features of confirmed TB can serve as cornerstones for diagnosing of TB, when culture is not available. Objective To evaluate the sensitivity of diagnostic criteria of TB, clinical and radiological manifestation of TB and drug susceptibility of MT isolated also. Methods All consecutive children (53 in total) up to age 14 diagnosed with bacteriologically confirmed TB during 01.01.2001. -01.12.2003. were prospectively evaluated for reasons mentioned above. Results Of the 53 children identified all but one had respiratory tract TB. 17(32,1 %) children were under 4 years of age, 9 (17%) children were 5-9 years old, but 27 (50,9%) patients were 10-14 years old. During evaluation data on TB source case were found in addition in 13 children and total TB contact history was positive in 37 (69,8%) patients. All clinical and radiographical forms of respiratory tract TB were diagnosed. The most common encountered forms were intrathoracic adenopathy in 10 (18,9%) cases and TB pneumonia in 6 (11,3%) cases in children aged 10-14 years. lnthrathoracic adenopathy associated with segmental parenchymal lesion was the most common form in children under 4 years of age -7 (13,2%) cases respectively.

    Full Text Available Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients′ sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25 represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25. Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15. Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15, orgasmic function (IIEF-9 and -10, sexual desire (IIEF-11 and -12, intercourse satisfaction (IIEF-6-8, and overall satisfaction (IIEF-13 and -14. Then, we also used Quality of Erection Questionnaire (QEQ, Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS and Self-Esteem and Relationship (SEAR to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

    Laparoscopic partial splenectomy (LPS) theoretically maintains long-term splenic immune function for children with hereditary spherocytosis (HS). Our goal was to review our results after LPS and to determine if specific genetic mutations influence outcome. All children with HS undergoing LPS between 2005 and 2016 were reviewed. Thirty-one children underwent LPS (16 male) at a median age of 9 (range 2-18) years. All experienced an increase in hemoglobin and decrease in reticulocyte count early after LPS and at last follow-up. Twenty-two were sent for genetic analysis. Mutations in α-spectrin, β-spectrin, and Ankyrin were identified in 6, 5, and 11 patients, respectively. Gene mutation was not correlated with complications, perioperative transfusion, length of hospital stay, or median hemoglobin, platelet, or reticulocyte counts. Three children required completion splenectomy at 10.9, 6.9, and 3.2years post-LPS, each with a different gene mutation. LPS is effective in reversing anemia and reducing reticulocytosis. So far less than 10% have required completion splenectomy, and those children did benefit from delaying the risks of asplenia. In this preliminary analysis, genetic mutation did not influence outcome after LPS. A larger multicenter study is necessary to further investigate potential correlations with specific genetic mutations. Prognosis Study. IV. Copyright © 2018. Published by Elsevier Inc.

    The purpose of the study was to understand the relationship between teachers' beliefs and understandings of climate change and their instructional practices to determine if and how they impact student outcomes. Limited research has been done in the area of teacher beliefs on climate change, their instruction, and resulting student outcomes. This study contributes to the greater understanding of teachers' beliefs and impact on climate change curriculum implementation. The study utilized a mixed methods approach to data collection and analysis. Data were collected in the form of classroom observations, surveys, and interviews from teachers and students participating in the study over a four-month period. Qualitative and quantitative findings were analyzed through thematic coding and descriptive analysis and compared in an effort to triangulate findings. The results of the study suggest teachers and students believe climate change is occurring and humans are largely to blame. Personal beliefs are important when teaching controversial topics, such as climate change, but participants maintained neutrality within their instruction of the topic, as not to appear biased or influence students' decisions about climate change, and avoid political controversy in the classroom. Overall, the study found teachers' level of understandings and beliefs about climate change had little impact on their instruction and resulting student outcomes. Based on the findings, simply adding climate change to the existing science curriculum is not sufficient for teachers or students. Teachers need to be better prepared about effective pedagogical practices of the content in order to effectively teach a climate-centered curriculum. The barriers that exist for the inclusion of teachers' personal beliefs need to be removed in order for teachers to assert their own personal beliefs about climate change within their classroom instruction. Administrators and stakeholders need to support science

    The use of nonstandardized and inadequately validated outcome measures in atopic eczema trials is a major obstacle to practising evidence-based dermatology. The Harmonising Outcome Measures for Eczema (HOME) initiative is an international multiprofessional group dedicated to atopic eczema outcomes research. In June 2011, the HOME initiative conducted a consensus study involving 43 individuals from 10 countries, representing different stakeholders (patients, clinicians, methodologists, pharmaceutical industry) to determine core outcome domains for atopic eczema trials, to define quality criteria for atopic eczema outcome measures and to prioritize topics for atopic eczema outcomes research. Delegates were given evidence-based information, followed by structured group discussion and anonymous consensus voting. Consensus was achieved to include clinical signs, symptoms, long-term control of flares and quality of life into the core set of outcome domains for atopic eczema trials. The HOME initiative strongly recommends including and reporting these core outcome domains as primary or secondary endpoints in all future atopic eczema trials. Measures of these core outcome domains need to be valid, sensitive to change and feasible. Prioritized topics of the HOME initiative are the identification/development of the most appropriate instruments for the four core outcome domains. HOME is open to anyone with an interest in atopic eczema outcomes research. © 2012 John Wiley & Sons A/S.

    To compare clinical outcomes of cataract surgery in eyes with and without pseudoexfoliation (PXF). Retrospective deidentified data analysis. A total of 123 PXF and 4776 non-PXF eyes of patients who underwent cataract surgery. We compared data on visual acuity, Visual Function Questionnaire (VFQ)-based quality of life, and complications in PXF and non-PXF eyes from the Veterans Affairs (VA) Ophthalmic Surgery Outcomes Data Project across 5 VA medical centres. Pupillary expansion devices were used in 31 (25.2%) PXF cases and 398 (8.4%) non-PXF cases (p < 0.0001). Capsular tension rings were used in 6 (4.9%) PXF cases and 55 (1.2%) non-PXF cases (p < 0.004). The following complications occurred more frequently in PXF cases: zonular dehiscence without vitrectomy (4 [3.3%] PXF cases vs 40 [0.8%] non-PXF cases p = 0.02), persistent inflammation (28 [24.1%] vs 668 [14.5%]; p = 0.007), and persistent intraocular pressure elevation (5 [4.3%] vs 68 [1.5%]; p = 0.03). Best corrected visual acuity (BCVA) improved in both groups after 1 month, but 87 (83.7%) PXF cases achieved postoperative BCVA better than or equal to 20/40 compared to 3991 (93.8%) non-PXF cases (p = 0.0003). There was no significant difference in the postoperative composite VFQ scores between PXF (82.1 ± 16.9) and non-PXF cases (84.2 ± 16.8, p = 0.09). Several complications occurred more frequently in the PXF group compared to the non-PXF group, and fewer PXF cases achieved BCVA better than or equal to 20/40. Despite this, both groups experienced similar improvement in vision-related quality of life after cataract surgery. Published by Elsevier Inc.

    Objective: Heller myotomy has been shown to be an effective primary treatment of achalasia. However, many physicians treating patients with achalasia continue to offer endoscopic therapies before recommending operative myotomy. Herein we report outcomes in 209 patients undergoing Heller myotomy with the majority (74%) undergoing myotomy as secondary treatment of achalasia. Methods: Data on all patients undergoing operative management of achalasia are collected prospectively. Over a 9-year period (1994–2003), 209 patients underwent Heller myotomy for achalasia. Of these, 154 had undergone either Botox injection and/or pneumatic dilation preoperatively. Preoperative, operative, and long-term outcome data were analyzed. Statistical analysis was performed with multiple χ2 and Mann-Whitney U analyses, as well as ANOVA. Results: Among the 209 patients undergoing Heller myotomy for achalasia, 154 received endoscopic therapy before being referred for surgery (100 dilation only, 33 Botox only, 21 both). The groups were matched for preoperative demographics and symptom scores for dysphagia, regurgitation, and chest pain. Intraoperative complications were more common in the endoscopically treated group with GI perforations being the most common complication (9.7% versus 3.6%). Postoperative complications, primarily severe dysphagia, and pulmonary complications were more common after endoscopic treatment (10.4% versus 5.4%). Failure of myotomy as defined by persistent or recurrent severe symptoms, or need for additionally therapy including redo myotomy or esophagectomy was higher in the endoscopically treated group (19.5% versus 10.1%). Conclusion: Use of preoperative endoscopic therapy remains common and has resulted in more intraoperative complications, primarily perforation, more postoperative complications, and a higher rate of failure than when no preoperative therapy was used. Endoscopic therapy for achalasia should not be used unless patients are not candidates for

    To evaluate long-term outcome after high-precision radiotherapy (RT) of meningioma patients in terms of survival and side effects. We analyzed 275 meningioma cases: 147 low-grade and 43 high-grade meningiomas (WHO II: n = 40, III: n = 3). In all, 85 patients had no pathologically confirmed histology but were determined as low-grade based on multimodal imaging. Surgery was performed in 183 cases. RT was delivered as either radiosurgery (RS, n = 16), fractionated stereotactic radiotherapy (FSRT, n = 241), or intensity-modulated radiation therapy (IMRT, n = 18). Of 218 patients contacted for patient-reported-outcome (PRO), 207 responded (95%). Median follow-up was 7.2 years. For low-grade meningioma the survival rate (OS) was 97% at 3 years, 85% at 10 years, and 64% at 15 years, for atypical meningioma 91% at 3 years, 62% at 10 years, and 50% at 15 years. Local control rate (PFS) for low-grade meningioma was 91% at 3 years, 87% at 5 years, and 86% at 10 years, for atypical cases 67% at 3 years and 55% at 5 years. Of all, 3.0% of patients reported worsened or new symptoms grade ≥3 during RT and the first 6 months thereafter; 17.5% reported a deterioration after more than 2 years. We found the prognostic factors tumor volume and age significantly influencing OS and PFS. Complemented by PRO, we found long-term low toxicity rates in addition to excellent local control. Thus, due to the beneficial risk-benefit profile of benign and high-risk meningiomas, RT should be performed as adjuvant treatment and should not be postponed until tumor progression. (orig.)

    Stereotactic Body Radiation Therapy (SBRT) was introduced clinically more than twenty years ago, and many subsequent publications have reported safety and efficacy data. The AAPM Working Group on Biological Effects of Hypofractionated Radiotherapy/SBRT (WGSBRT) extracted published treatment outcomes data from extensive literature searches to summarize and construct tumor control probability (TCP) and normal tissue complication probability (NTCP) models for six anatomical regions: Cranial, Head and Neck, Thoracic, Abdominal, Pelvic, and Spinal. In this session, we present the WGSBRT’s work for cranial sites, and recurrent head and neck cancer. From literature-based data and associated models, guidelines to aid with safe and effective hypofractionated radiotherapy treatment are being determined. Further, the ability of existing and proposed radiobiological models to fit these data is considered as to the ability to distinguish between the linear-quadratic and alternative radiobiological models such as secondary cell death from vascular damage, immunogenic, or bystander effects. Where appropriate, specific model parameters are estimated. As described in “The lessons of QUANTEC,” (1), lack of adequate reporting standards continues to limit the amount of useful quantitative information that can be extracted from peer-reviewed publications.

    The essential static patellar stabilizer is a normal-shaped trochlear groove. A dysplastic groove destabilizes the patella. Trochleoplasty approaches this underlying condition and reshapes the trochlea. However, studies have reported on trochleoplasty for revision cases or as accompanied by other interventions. The effect of trochleoplasty alone remains unexplained. To introduce trochleoplasty as a stand-alone treatment for recurrent patellar dislocation and to compare its pre- to postoperative functional and clinical variables. Case series; Level of evidence, 4. A trochleoplasty was performed in 50 knees (27 right) in 44 patients (30 females; mean ± SD age, 15.6 ± 2.0 years). The indication for surgery was recurrent patellar dislocation not responding to nonoperative treatment (>6 months), with types B through D dysplasia and closed or closing physes in adolescents aged 10 to 20 years. Assessment included J-sign and apprehension test, Kujala and Lysholm scores, patients' subjective assessment and activity level according to the International Knee Documentation Committee questionnaire, and patients' overall satisfaction. The Caton-Deschamps ratio and the lateral condyle index were measured. Pre- versus postoperative values were compared with a paired Wilcoxon signed-rank test. The minimum follow-up was 24 months (33 ± 10.6 months). The Kujala score improved from 71 preoperatively to 92 postoperatively (P debridement. In this study, trochleoplasty as a solitary treatment for recurrent patellofemoral dislocations in patients with trochlear dysplasia resulted in good clinical outcomes if severe torsional and axial malalignment was excluded. Kujala and Lysholm scores increased postoperatively, as well as subjective International Knee Documentation Committee assessment of outcomes, activity level, and overall satisfaction. © 2016 The Author(s).

    To determine whether concurrently performed operations are associated with an increased risk for adverse events. Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety. Propensity-score-matched cohorts were constructed to compare death or serious morbidity (DSM), unplanned reoperation, and unplanned readmission in concurrent versus non-concurrent operations. Multilevel hierarchical regression was used to account for the clustered nature of the data while controlling for procedure and case mix. There were 1430 (32.3%) surgeons from 390 (77.7%) hospitals who performed 12,010 (2.3%) concurrent operations. Plastic surgery (n = 393 [13.7%]), otolaryngology (n = 470 [11.2%]), and neurosurgery (n = 2067 [8.4%]) were specialties with the highest proportion of concurrent operations. Spine procedures were the most frequent concurrent procedures overall (n = 2059/12,010 [17.1%]). Unadjusted rates of DSM (9.0% vs 7.1%; P < 0.001), reoperation (3.6% vs 2.7%; P < 0.001), and readmission (6.9% vs 5.1%; P < 0.001) were greater in the concurrent operation cohort versus the non-concurrent. After propensity score matching and risk-adjustment, there was no significant association of concurrence with DSM (odds ratio [OR] 1.08; 95% confidence interval [CI] 0.96-1.21), reoperation (OR 1.16; 95% CI 0.96-1.40), or readmission (OR 1.14; 95% CI 0.99-1.29). In these analyses, concurrent operations were not detected to increase the risk for adverse outcomes. These results do not lessen the need for further studies, continuous self-regulation and proactive disclosure to patients.

    To determine the epidemiological profile of women admitted for urinary tract infection as well as to verify the most prevalent agents and response to antibiotic therapy. A retrospective study of 106 pregnant women admitted to a university hospital for urinary tract infection treatment during the period between January 2007 to December 2010. The evaluation was based on analysis of the medical records of these pregnant women, with the observation of hospitalization and pregnancy data, as well as its outcome. Statistical analysis was performed using Statistical Package for the Social Science, version 15.0. The bilateral Fisher exact test and Student's t test were used for data analysis, as well as descriptive statistical methods. Positive urine cultures were observed in 60.5% of pregnant women admitted due to urinary tract infection. The most frequent infectious agent was Escherichia coli and no difference in resistance, recurrence or complications was observed between the most frequent etiologic agents. Pregnant women with previous UTI had a higher recurrence risk (OR=10.8; p<0.05). The antibiotics most commonly used during hospitalization were ampicillin and cefazolin. Change of therapeutic agent due to bacterial resistance occurred in 11.9% of patients who took cefazolin and in 20% of patients who took ampicillin (OR=5.5; p<0.05). The rate of gestational complications was the same for both treatments. There was no difference in mean number of days of hospitalization between the treatments. In the studied population ampicillin showed a higher rate of bacterial resistance than cefazolin, requiring a larger number of treatment regimen exchanges, without resulting in differences in clinical outcome or time of hospitalization.

    The purpose of this study was to evaluate whether specific MRI features, such as axial location and type of herniation, are associated with outcomes of symptomatic lumbar disc herniation patients treated with spinal manipulation therapy (SMT). MRI and treatment outcome data from 68 patients were included in this prospective outcomes study. Pain numerical rating scale (NRS) and Oswestry physical disability questionnaire (OPDQ) levels were measured at baseline. The Patients Global Impression of Change scale, the NRS and the OPDQ were collected at 2 weeks, 1, 3, 6 months and 1 year. One radiologist and 2 chiropractic medicine master's degree students analyzed the MRI scans blinded to treatment outcomes. κ statistics assessed inter-rater reliability of MRI diagnosis. The proportion of patients reporting relevant improvement at each time point was compared based on MRI findings using the chi-square test. The t test and ANOVA compared the NRS and OPDQ change scores between patients with various MRI abnormalities. A higher proportion of patients with disc sequestration reported relevant improvement at each time point but this did not quite reach statistical significance. Patients with disc sequestration had significantly higher reduction in leg pain at 1 month compared to those with extrusion (P = .02). Reliability of MRI diagnosis ranged from substantial to perfect (K = .733-1.0). Patients with sequestered herniations treated with SMT to the level of herniation reported significantly higher levels of leg pain reduction at 1 month and a higher proportion reported improvement at all data collection time points but this did not reach statistical significance.

    Health promotion (HP) interventions have outcomes that go beyond health. Such broader nonhealth outcomes are usually neglected in economic evaluation studies. To allow for their consideration, insights are needed into the types of nonhealth outcomes that HP interventions produce and their relative importance compared with health outcomes. This study explored consumer preferences for health and nonhealth outcomes of HP in the context of lifestyle behavior change. A discrete choice experiment was conducted among participants in a lifestyle intervention (n = 132) and controls (n = 141). Respondents made 16 binary choices between situations that can be experienced after lifestyle behavior change. The situations were described by 10 attributes: future health state value, start point of future health state, life expectancy, clothing size above ideal, days with sufficient relaxation, endurance, experienced control over lifestyle choices, lifestyle improvement of partner and/or children, monetary cost per month, and time cost per week. With the exception of "time cost per week" and "start point of future health state," all attributes significantly determined consumer choices. Thus, both health and nonhealth outcomes affected consumer choice. Marginal rates of substitution between the price attribute and the other attributes revealed that the attributes "endurance," "days with sufficient relaxation," and "future health state value" had the greatest impact on consumer choices. The "life expectancy" attribute had a relatively low impact and for increases of less than 3 years, respondents were not willing to trade. Health outcomes and nonhealth outcomes of lifestyle behavior change were both important to consumers in this study. Decision makers should respond to consumer preferences and consider nonhealth outcomes when deciding about HP interventions.

    To present for black and white patients with medically uncontrolled glaucoma 10-year results of treatment with 1 of 2 randomly assigned surgical intervention sequences. Randomized clinical trial. Three hundred thirty-two black patients (451 eyes) and 249 white patients (325 eyes). Eyes had glaucoma that could not be controlled with medications alone. Eyes were randomly assigned to 1 of 2 sequences: argon laser trabeculoplasty (ALT)-trabeculectomy-trabeculectomy (ATT) or trabeculectomy-ALT-trabeculectomy (TAT). Second and third interventions were offered after failure of the preceding intervention. Minimum required intraocular pressure (IOP) for intervention failure ranged upward from 18 mmHg, the value depending on whether recent optic disc or visual field (VF) deterioration occurred, and on the magnitude of the field defect. Patients were observed every 6 months, with total potential follow-up ranging from 8 years, 4 months to 13 years. The averages over follow-up of (1) the percentage of eyes having moderate loss of VF and (2) the percentage of eyes having moderate loss of visual acuity (VA). Race-treatment interactions in VF and VA loss are significant for the 2 main outcome measures; therefore, results of treatment sequence differences are presented by race. In black patients the average percent of eyes with VF loss was less in the ATT sequence than in the TAT sequence, a difference that is not statistically significant at any visit. In white patients, conversely, after 18 months the average percent of eyes with VF loss was less in the TAT sequence, a difference that increases and is statistically significant in years 8 to 10. In both black and white patients, the average percent of eyes with VA loss was less in the ATT sequence; this difference is statistically significant throughout 10 follow-up years in black patients and is statistically significant only for the first year in white patients. In both black and white patients, average IOP reductions were

  20. Mercury in fish and adverse reproductive outcomes: results from South Carolina

    Science.gov (United States)

    2014-01-01

    Background Mercury is a metal with widespread distribution in aquatic ecosystems and significant neurodevelopmental toxicity in humans. Fish biomonitoring for total mercury has been conducted in South Carolina (SC) since 1976, and consumption advisories have been posted for many SC waterways. However, there is limited information on the potential reproductive impacts of mercury due to recreational or subsistence fish consumption. Methods To address this issue, geocoded residential locations for live births from the Vital Statistics Registry (1995–2005, N = 362,625) were linked with spatially interpolated total mercury concentrations in fish to estimate potential mercury exposure from consumption of locally caught fish. Generalized estimating equations were used to test the hypothesis that risk of low birth weight (LBW, mercury in fish, after adjustment for confounding. Separate analyses estimated term LBW and PTB risks using residential proximity to rivers with fish consumption advisories to characterize exposure. Results Term LBW was more likely among women residing in areas in the upper quartile of predicted total mercury in fish (odds ratio [OR] = 1.04; 95% confidence interval [CI]: 1.00-1.09) or within 8 kilometers of a river with a ‘do not eat’ fish advisory (1.05; 1.00-1.11) compared to the lowest quartile, or rivers without fish consumption restrictions, respectively. When stratified by race, risks for term LBW or PTB were 10-18% more likely among African-American (AA) mothers living in areas with the highest total fish mercury concentrations. Conclusions To our knowledge, this is the first study to examine the relationship between fish total mercury concentrations and adverse reproductive outcomes in a large population-based sample that included AA women. The ecologic nature of exposure assessment in this study precludes causal inference. However, the results suggest a need for more detailed investigations to characterize patterns of local

    The NHS Outcomes Framework for England has identified recovery from major injury as an important clinical area. At present, there are no established outcome indicators. As more patients survive major trauma, outcomes will need to be measured in terms of morbidity and not mortality alone. To make recommendations for a selection of outcome measures that could be integrated into National Clinical Audit data collection and form part of clinical governance requirements for Regional Trauma Networks (RTNs) and measures by which RTNs are held to account by government. Specific focus was given to acute care and rehabilitation for both adults and children. A Multiprofessional, multidisciplinary expert group reviewed the current evidence on outcome measures for major trauma in the adult and children's populations, informed by a systematic review carried out jointly by the Trauma Audit and Research Network (TARN) and the Cochrane Injuries Group. A structured discussion covered functional and quality of life outcome measures as well as patient experience and indicators such as return to work, education and social dependency. For the adult population the group agreed with the in-hospital performance and hospital discharge measures recommended in the TARN and Cochrane systematic review. Concerning longer-term outcome indicators, the group suggested the use of the Glasgow Outcome Scale - Extended (GOS-E) and European Quality of Life 5D (EQ-5D) with consideration to be given to the World Health Organisation Quality of Life survey (WHO-QoL). For patients who had ongoing inpatient rehabilitation needs the group thought the measurement of the Rehabilitation Complexity Scale (RCS) and Functional Independence Measure (FIM) were important in total brain injury and, the American Spinal Injury Association Impairment Scale (ASIA) and Spinal Cord Independence Measure (SCIM) in spinal cord injury. For children the group recommended the use of the King's Outcome Scale for Childhood Head Injury

    Hepatitis C virus (HCV) is a global health care problem. Diagnosis of HCV infection is mainly based on the detection of anti-HCV antibodies as a screening test with serum samples. Recombinant immunoblot assays are used as supplemental tests and for the final detection and quantification of HCV RNA in confirmatory tests. In this study, we aimed to compare the HCV core antigen test with the HCV RNA assay for confirming anti-HCV results to determine whether the HCV core antigen test may be used as an alternative confirmatory test to the HCV RNA test and to assess the diagnostic values of the total HCV core antigen test by determining the diagnostic specificity and sensitivity rates compared with the HCV RNA test. Sera from a total of 212 treatment-naive patients were analyzed for anti-HCV and HCV core antigen both with the Abbott Architect test and with the molecular HCV RNA assay consisting of a reverse transcription-PCR method as a confirmatory test. The diagnostic sensitivity, specificity, and positive and negative predictive values of the HCV core antigen assay compared to the HCV RNA test were 96.3%, 100%, 100%, and 89.7%, respectively. The levels of HCV core antigen showed a good correlation with those from the HCV RNA quantification (r = 0.907). In conclusion, the Architect HCV antigen assay is highly specific, sensitive, reliable, easy to perform, reproducible, cost-effective, and applicable as a screening, supplemental, and preconfirmatory test for anti-HCV assays used in laboratory procedures for the diagnosis of hepatitis C virus infection.

    Purpose: To prospectively analyze the effectiveness of computed tomography-guided percutaneous lumbar sympathectomy (CTLS) in patients with peripheral arterial occlusive disease in relation to angiographic findings and vascular risk factors. Methods: Eighty-three patients were treated by CTLS. After clinical evaluation of the risk profile and diagnostic intraarterial digital subtraction arteriography, 14 patients underwent unilateral, and 69 bilateral one-level treatment. Follow-up studies took place on the day following the intervention, after 3 weeks, and after 3 months. Results: A total of 152 interventions were performed in 83 patients. After 3 months, clinical examination of 54 patients (5 patients had died, 24 were lost to follow-up) revealed improvement in 46% (25/54), no change in 39% (21/54), and worsening (amputation) in 15% (8/54). There was no significant statistical correlation among any of the analyzed factors (diabetes mellitus, arterial hypertension, smoking, hyperlipidemia, obesity, hyperuricemia, number of risk factors, ankle-arm index, and angiography score) and the outcome after CTLS. Three major complications occurred: one diabetic patient developed a retroperitoneal abscess 2 weeks after CTLS, and in two other patients ureteral strictures were detected 3 months and 2 years after CTLS, respectively. Conclusion: As no predictive criteria for clinical improvement in an individual patient could be identified, CTLS, as a safe procedure, should be employed on a large scale in patients who are unsuitable for treatment by angioplasty or revascularization

    Learners frequently need to access increasingly complex information to help them understand our changing world. More and more libraries are transforming themselves into places where learners not only access STEM information, but interact with professionals and undertake hands-on learning. Libraries are beginning to position themselves as part of learning ecosystems that contribute to a collective impact on the community. Traveling STEM exhibits are catalyzing these partnerships and engaging students, families, and adults in repeat visits through an accessible venue: their public library. This talk will explore impacts from two STAR Library Network's (STAR_Net) exhibitions (Discover Earth and Discover Tech) on partnerships, the circulation of STEM resources, and the engagement of learners. The STAR_Net project's summative evaluation utilized mixed methods to investigate project implementation and its outcomes. Methods included pre- and post-exhibit surveys administered to staff from each library that hosted the exhibits; interviews with staff from host libraries; patron surveys; exhibit-related circulation records; web metrics regarding the online STAR_Net community of practice; and site visits. The latter provides a more complete view of impacts on the community, including underserved audiences. NASA@ My Library is a new STAR_Net initiative, which provides STEM facilitation kits, training, and other resources to 75 libraries nationwide. Initial results will be presented that show high levels of engagement by librarians and strong response rate from patrons on surveys.

    This study aimed to evaluate the clinical outcomes and structural integrity of arthroscopic repair of intratendinous rotator cuff tear. Patients who were diagnosed with an intratendinous tear but in whom conservative treatment failed were selected and underwent arthroscopic repair. Between 2008 and 2014, a total of 30 patients (6 men, 24 women; mean age, 59 ± 3.7 years) met the inclusion criteria and were followed up. The mean follow-up period was 26.3 ± 0.7 months. The results were evaluated using the University of California at Los Angeles (UCLA) score, the Society of the American Shoulder and Elbow Surgeons rating scale (ASES) questionnaire, and the visual analog scale (VAS) and range of motion (ROM) were measured preoperatively and at final follow-up. Magnetic resonance imaging (MRI) was performed preoperatively and at 6.7 ± 0.2 months postoperatively. Postoperative MRI was performed on 27 out of 30 patients and analysed using the Sugaya classification. Corresponding to the preoperative MRI findings, arthroscopic findings of intratendinous tears were observed in all 30 patients. The mean active forward elevation ROM was 137.3° ± 15.4° before surgery and 168.8° ± 15.2° at the final follow-up. The internal and external rotations at abduction were 31.7° ± 5.1° and 63.0° ± 11.6° before surgery, respectively, and 60.5° ± 8.0° and 75.2° ± 10.8° after surgery, respectively. The UCLA score improved from of 20.1 ± 7.4 points preoperative to 28.4 ± 5.5 points at the final follow-up. The ASES score improved from 55.7 ± 15.3 points preoperative to 82.6 ± 9.7 points postoperatively. The VAS for pain score decreased from 6.4 ± 1.2 points preoperative to 1.6 ± 0.9 points postoperative. Satisfactory outcomes (excellent/good) in terms of UCLA and ASES scores were observed in 29 of 30 patients. Based on Sugaya classification, grades I, II, and III structural integrities were observed in 9

    OBJECTIVE Previous Hydrocephalus Clinical Research Network (HCRN) retrospective studies have shown a 15% difference in rates of conversion to permanent shunts with the use of ventriculosubgaleal shunts (VSGSs) versus ventricular reservoirs (VRs) as temporization procedures in the treatment of hydrocephalus due to high-grade intraventricular hemorrhage (IVH) of prematurity. Further research in the same study line revealed a strong influence of center-specific decision-making on shunt outcomes. The primary goal of this prospective study was to standardize decision-making across centers to determine true procedural superiority, if any, of VSGS versus VR as a temporization procedure in high-grade IVH of prematurity. METHODS The HCRN conducted a prospective cohort study across 6 centers with an approximate 1.5- to 3-year accrual period (depending on center) followed by 6 months of follow-up. Infants with premature birth, who weighed less than 1500 g, had Grade 3 or 4 IVH of prematurity, and had more than 72 hours of life expectancy were included in the study. Based on a priori consensus, decisions were standardized regarding the timing of initial surgical treatment, upfront shunt versus temporization procedure (VR or VSGS), and when to convert a VR or VSGS to a permanent shunt. Physical examination assessment and surgical technique were also standardized. The primary outcome was the proportion of infants who underwent conversion to a permanent shunt. The major secondary outcomes of interest included infection and other complication rates. RESULTS One hundred forty-five premature infants were enrolled and met criteria for analysis. Using the standardized decision rubrics, 28 infants never reached the threshold for treatment, 11 initially received permanent shunts, 4 were initially treated with endoscopic third ventriculostomy (ETV), and 102 underwent a temporization procedure (36 with VSGSs and 66 with VRs). The 2 temporization cohorts were similar in terms of sex, race

    Adverse birth outcomes such as preterm birth, low-birth weight, and infant mortality continue to disproportionately affect black and poor infants in the United States. Improvements in healthcare quality and access have not eliminated these disparities. The objective of this review was to consider societal factors, including suboptimal education, income inequality, and residential segregation, that together lead to toxic environmental exposures and psychosocial stress. Many toxic chemicals, as well as psychosocial stress, contribute to the risk of adverse birth outcomes and black women often are more highly exposed than white women. The extent to which environmental exposures combine with stress and culminate in racial disparities in birth outcomes has not been quantified but is likely substantial. Primary prevention of adverse birth outcomes and elimination of disparities will require a societal approach to improve education quality, income equity, and neighborhoods.

    Full Text Available Introduction: The objective of our study was to describe surgical outcomes of Deloyers procedure in our referral center, and to compare the results of patients with and without protective ileostomy. Methods: Patients undergoing a Deloyers procedure from 2013 to 2016 were prospectively included. General characteristics, intraoperative variables, postoperative course, and functional outcomes were analyzed. Patients were compared into two groups: group (1 patients undergoing Deloyers procedure without ileostomy, and group (2 Deloyers procedure with protective ileostomy. Results: Sixteen patients undergoing isoperistaltic transposition of the right colon remnant were included, of which 9 (63% were males with a median age of 47 (range 22–76 years. The main surgical indication was the restoration of bowel transit (62.5%. There was higher major morbidity rate in the Deloyers procedure with protective ileostomy group, but without statistical significance (20% vs. 9%, p = 0.92. No leaks or deaths were reported. The length of hospital stay was 7 days. The mean number of bowel movements per day was 4 at 18 months of follow up. Only four (25% patients used irregularly loperamide. Conclusions: The Deloyers procedure has satisfactory results and is reproducible with low morbidity. The major and minor morbidity rates were similar between groups, suggesting that the costs and risks of a second procedure can be avoided by providing a safe primary anastomosis.

    Purpose To improve ischemic stroke outcome prediction using imaging information from a prospective cohort who received admission CT angiography (CTA). Methods In a prospectively designed study, 649 stroke patients diagnosed with acute ischemic stroke had admission NIH stroke scale scores, noncontrast CT (NCCT), CTA, and 6-month outcome assessed using the modified Rankin scale (mRS) scores. Poor outcome was defined as mRS>2. Strokes were classified as “major” by the (1) Alberta Stroke Program Early CT Score (ASPECTS+) if NCCT ASPECTS was≤7; (2) Boston Acute Stroke Imaging Scale (BASIS+) if they were ASPECTS+ or CTA showed occlusion of the distal internal carotid, proximal middle cerebral, or basilar arteries; and (3) NIHSS for scores>10. Results Of 649 patients, 253 (39.0%) had poor outcomes. NIHSS, BASIS, and age, but not ASPECTS, were independent predictors of outcome. BASIS and NIHSS had similar sensitivities, both superior to ASPECTS (p10/BASIS+ had poor outcomes, versus 21.5% (77/358) with NIHSS≤10/BASIS− (p10/BASIS+ compared to patients who are NIHSS≤10/BASIS−; the odds ratio is 5.4 (95% CI: 3.5 to 8.5) when compared to patients who are only NIHSS>10 or BASIS+. Conclusions BASIS and NIHSS are independent outcome predictors. Their combination is stronger than either instrument alone in predicting outcomes. The findings suggest that CTA is a significant clinical tool in routine acute stroke assessment. PMID:22276182

    To determine if fractional flow reserve guided percutaneous coronary intervention (FFR-guided PCI) is associated with reduced ischemic myocardium compared with angiography-guided PCI. Although FFR-guided PCI has been shown to improve outcomes, it remains unclear if it reduces the extent of ischemic myocardium at risk compared with angiography-guided PCI. We evaluated 380 patients (190 FFR-guided PCI cases and 190 propensity-matched controls) who underwent PCI from 2009 to 2014. Clinical, laboratory, angiographic, stress testing, and major adverse cardiac events [MACE] (all-cause mortality, recurrence of MI requiring PCI, stroke) data were collected. Mean age was 63 ± 11 years; the majority of patients were males (76%) and Caucasian (77%). Median duration of follow up was 3.4 [Range: 1.9, 5.0] years. Procedural complications including coronary dissection (2% vs. 0%, P = .12) and perforation (0% vs. 0%, P = 1.00) were similar between FFR-guided and angiography-guided PCI patients. FFR-guided PCI patients had lower unadjusted (14.7% vs. 23.2%, P = .04) and adjusted [OR = 0.58 (95% CI: 0.34-0.98)] risk of repeat revascularization at one year. FFR-guided PCI patients were less likely (23% vs. 32%, P = .02) to have ischemia and had lower (5.9% vs. 21.1%, P guided PCI, FFR-guided PCI results in less repeat revascularization and a lower incidence of post PCI ischemia translating into improved survival, without an increase in complications. © 2018 Wiley Periodicals, Inc.

    Curative management of deep infiltrating endometriosis requires complete removal of all endometriotic implants. Surgical approach to rectal involvement has become a topic of debate given potential postoperative bowel dysfunction and complications. This study aims to assess long-term postoperative evacuation and incontinence outcomes after laparoscopic segmental rectal resection for deep infiltrating endometriosis involving the rectal wall. This is a retrospective study of prospectively collected data. This single-center study was conducted at the University Hospital of Bern, Switzerland. Patients with deep infiltrating endometriosis involving the rectum undergoing rectal resection from June 2002 to May 2011 with at least 24 months follow-up were included. Aside from endometriosis-related symptoms, detailed symptoms on evacuation (points: 0 (best) to 21 (worst)) and incontinence (0-24) were evaluated by using a standardized questionnaire before and at least 24 months after surgery. Of 66 women who underwent rectal resection, 51 were available for analyses with a median follow-up period of 86 months (range: 26-168). Forty-eight patients (94%) underwent laparoscopic resection (4% converted, 2% primary open), with end-to-end anastomosis in 41 patients (82%). Two patients (4%) had an anastomotic insufficiency; 1 case was complicated by rectovaginal fistula. Dysmenorrhea, nonmenstrual pain, and dyspareunia substantially improved (p endometriosis including the rectal wall is associated with good results in endometriotic-related symptoms, although patients should be informed about possible postoperative impairments in evacuation and incontinence. However, its clinical impact does not outweigh the benefit that can be achieved through this approach. See Video Abstract at http://links.lww.com/DCR/A547.

    The aim of this study was to explore the heterogeneous association of consumption of food away from home (FAFH) with individual body mass outcomes including body mass index and waist circumference over the entire conditional distribution of each outcome. Information on 16,403 adults obtained from nationally representative data on nutrition and behavior in Korea was used. A quantile regression model captured the variability of the association of FAFH with body mass outcomes across the entire conditional distribution of each outcome measure. Heavy FAFH consumption was defined as obtaining ≥1400 kcal from FAFH on a single day. Heavy FAFH consumption, specifically at full-service restaurants, was significantly associated with higher body mass index (+0.46 kg/m2 at the 50th quantile, 0.55 at the 75th, 0.66 at the 90th, and 0.44 at the 95th) and waist circumference (+0.96 cm at the 25th quantile, 1.06 cm at the 50th, 1.35 cm at the 75th, and 0.96 cm at the 90th quantiles) with overall larger associations at higher quantiles. Findings of the study indicate that conventional regression methods may mask important heterogeneity in the association between heavy FAFH consumption and body mass outcomes. Further public health efforts are needed to improve the nutritional quality of affordable FAFH choices and nutrition education and to establish a healthy food consumption environment.

    The value of neurosurgical interventions after spontaneous intracerebral hemorrhage (SICH) is uncertain. We evaluated clinical outcomes in patients diagnosed with SICH within 3 hours of symptom onset who underwent hematoma evacuation or external ventricular drainage (EVD) of the hematoma in the Factor Seven for Acute Hemorrhagic Stroke Trial (FAST). FAST was a randomized, multicenter, double-blind, placebo-controlled trial conducted between May 2005 and February 2007 at 122 sites in 22 countries. Neurosurgical procedures (hematoma evacuation and external ventricular drainage) performed at any point after hospital admission were prospectively recorded. Clinical outcomes evaluated were post-SICH disability, as assessed by the modified Rankin Scale; neurologic impairment, as assessed by the National Institutes of Health Stroke Scale; and mortality at 90 days after SICH onset. The impact of neurosurgical procedures on clinical outcomes was evaluated using multivariate logistic regression analysis, controlling for relevant baseline characteristics. Fifty-five of 821 patients underwent neurosurgery. Patients who underwent hematoma evacuation or EVD were on average younger, had greater baseline neurologic impairment, and lower levels of consciousness compared with patients who did not undergo neurosurgery. After adjusting for these differences and other relevant baseline characteristics, we found that neurosurgery was generally associated with unfavorable outcomes at day 90. Among the patients who underwent hematoma evacuation, those with lobar ICH had less ICH expansion than those with deep gray matter ICH, and the smaller expansion was associated with lower mortality. ICH volume was substantially decreased in patients who underwent hematoma evacuation between 24 and 72 hours after hospital admission, and this was associated with better clinical outcome. In conclusion, a small number of patients who underwent neurosurgery in FAST exhibited no overall clinical benefit

    Patient-reported outcomes (PROs) promote patient-centered care by using PRO research results ("group-level data") to inform decision making and by monitoring individual patient's PROs ("individual-level data") to inform care. We investigated the interpretability of current PRO data presentation formats. This cross-sectional mixed-methods study randomized purposively sampled cancer patients and clinicians to evaluate six group-data or four individual-data formats. A self-directed exercise assessed participants' interpretation accuracy and ratings of ease-of-understanding and usefulness (0 = least to 10 = most) of each format. Semi-structured qualitative interviews explored helpful and confusing format attributes. We reached thematic saturation with 50 patients (44 % < college graduate) and 20 clinicians. For group-level data, patients rated simple line graphs highest for ease-of-understanding and usefulness (median 8.0; 33 % selected for easiest to understand/most useful) and clinicians rated simple line graphs highest for ease-of-understanding and usefulness (median 9.0, 8.5) but most often selected line graphs with confidence limits or norms (30 % for each format for easiest to understand/most useful). Qualitative results support that clinicians value confidence intervals, norms, and p values, but patients find them confusing. For individual-level data, both patients and clinicians rated line graphs highest for ease-of-understanding (median 8.0 patients, 8.5 clinicians) and usefulness (median 8.0, 9.0) and selected them as easiest to understand (50, 70 %) and most useful (62, 80 %). The qualitative interviews supported highlighting scores requiring clinical attention and providing reference values. This study has identified preferences and opportunities for improving on current formats for PRO presentation and will inform development of best practices for PRO presentation. Both patients and clinicians prefer line graphs across group-level data and individual

    This study aimed to determine predictors of BMI and recovery for outpatients with anorexia nervosa (AN). Patients were participants of the ANTOP (Anorexia Nervosa Treatment of Out-Patients) trial and randomized to focal psychodynamic therapy (FPT), enhanced cognitive behavior therapy (CBT-E), or optimized treatment as usual (TAU-O). N=169 patients participated in the one-year follow-up (T4). Outcomes were the BMI and global outcome (recovery/partial syndrome/full syndrome) at T4. We examined the following baseline variables as possible predictors: age, BMI, duration of illness, subtype of AN, various axis I diagnoses, quality of life, self-esteem, and psychological characteristics relevant to AN. Linear and logistic regression analyses were conducted to identify the predictors of the BMI and global outcome. The strongest positive predictor for BMI and recovery at T4 was a higher baseline BMI of the patients. Negative predictors for BMI and recovery were a duration of illness >6 years and a lifetime depression diagnosis at baseline. Additionally, higher bodily pain was significantly associated with a lower BMI and self-esteem was a positive predictor for recovery at T4. A higher baseline BMI and shorter illness duration led to a better outcome. Further research is necessary to investigate whether or not AN patients with lifetime depression, higher bodily pain, and lower self-esteem may benefit from specific treatment approaches.

    -infected patients treated for TB after laboratory confirmation of the diagnosis and TB/HIV co-infected patients who were so treated without diagnostic confirmation. METHODS: A retrospective cohort of TB/HIV co-infected patients who started TB treatment between July of 2002 and June of 2004 at an HIV/AIDS referral center in Recife, Brazil. The main exposure variable, laboratory confirmation of TB, was adjusted for three different sets of variables: sociodemographic variables; HIV/AIDS-related variables; and TB-related variables. In order to evaluate the statistical significance of the results, we calculated odds ratios, with 95% confidence intervals, and p values (from chi-square tests and likelihood ratio tests. RESULTS: A total of 262 patients were studied. No association was found between laboratory confirmation of the diagnosis of TB at treatment outset and unfavorable outcome, even after adjustment for confounders. In the final multiple logistic regression model, the following variables remained: the presence of other opportunistic diseases; CD4 lymphocyte count below 50 cells/mm³; viral load between 10,000 and 100,000 copies/mL; dyspnea; the disseminated form of TB; and change in the TB treatment regimen due to adverse reactions or intolerance. CONCLUSIONS: Our results suggest that TB treatment in TB/HIV co-infected patients without etiologic confirmation of TB, at the discretion of experienced physicians in referral centers, did not increase the risk of unfavorable outcomes. In addition, it allowed the identification of groups that should be closely monitored due to a greater risk of unfavorable outcomes.

    Full Text Available Purpose: This study was designed to evaluate the visual and anatomical outcomes after cataract surgery in diabetic patients with different intraoperative therapeutic strategies. Methods: The research design comprised of a multicentric, retrospective, interventional study conducted at 6 centers in Argentina, Brazil, Costa Rica, Puerto Rico, Spain, and Venezuela. We included 138 diabetic patients with at least 6-month follow-up following phacoemulsification and intraocular lens implantation. Best-corrected visual acuity (BCVA and central subfield thickness were collected at baseline and at 1-, 2-, 3-, and 6-month follow-up. Of these, 42 cases were not treated with any intraoperative coadjuvant medication (Group 1, 59 patients received intraoperative bevacizumab (Group 2 and 37 patients received intraoperative triamcinolone (4 mg/0.1 ml (Group 3. Results: The mean logMAR [± standard deviation (SD] BCVA improved from 0.82 (± 0.43 at baseline, to 0.14 (± 0.23 at 6-month follow-up (p<0.001 in Group 1; from 0.80 (± 0.48 to 0.54 (± 0.45 (p<0.001 in Group 2; and from 1.0 (± 0.40 to 0.46 (± 0.34 (p<0.001 in Group 3. The mean central subfield thickness increased from 263.57 µm (± 35.7 at baseline to 274.57 µm (± 48.7 at 6-month follow-up (p=0.088 in Group 1; from 316.02 µm (± 100.4 to 339.56 µm (± 145.3 (p=0.184 in Group 2; and from 259.18 µm (± 97.9 to 282.21 µm (± 87.24 (p=0.044 in Group 3. Conclusion: Diabetic patients may significantly benefit from cataract surgery. This study provides evidence to support the use of intravitreal triamcinolone or bevacizumab at the time of cataract surgery in cases with pre-existent diabetic macular edema or moderate-severe non-proliferative diabetic retinopathy.

    DIALOG assessed the prevalence and predictors of hypoglycaemia in patients with type 1 (T1DM) or insulin-treated type 2 diabetes mellitus (T2DM) in a real-life setting. In this observational study, insulin-treated patients (n=3048) completed prospective daily questionnaires reporting the frequency and consequences of severe/confirmed non-severe hypoglycaemia over 30 days. Patients (n=3743) also retrospectively reported severe hypoglycaemia over the preceding year. In this prospective survey, 85.3% and 43.6% of patients with T1DM and T2DM, respectively, reported experiencing at least one confirmed hypoglycaemic event over 30 days, while 13.4% and 6.4%, respectively, reported at least one severe event. Hypoglycaemia frequency increased with longer duration of diabetes and insulin therapy. Strongly predictive factors for hypoglycaemia were previous hypoglycaemia, >2 injections/day, BMIinsulin therapy>10 years. HbA1c level was not predictive of hypoglycaemia in either T1DM or T2DM. The confirmed hypoglycaemia rate was increased in the lowest compared with the highest tertile of HbA1c in T1DM, but not T2DM. At the time of enrolment, physicians reported severe hypoglycaemia in 23.6% and 11.9% of T1DM and T2DM patients, respectively, during the preceding year; the retrospective survey yielded frequencies of 31.5% and 21.7%, respectively. Also, severe hypoglycaemia led to medical complications in 10.7% and 7.8% of events in T1DM and T2DM patients, respectively, over 30 days. Using a unique combined prospective and retrospective approach, the DIALOG study found a relatively high frequency of hypoglycaemia among insulin-treated patients. These findings emphasize the importance of a patient-centred approach for managing diabetes in which hypoglycaemia risk evaluation is critical. ClinicalTrials.gov: NCT01628341.

    To describe the natural history, antenatal and postnatal therapy, and clinical outcomes of Australian patients with fetomaternal/neonatal alloimmune thrombocytopenia (NAIT) recorded in the Australian NAIT registry. Analysis of registry data of Australian mothers treated antenatally for NAIT and any fetus/newborn with thrombocytopenia (TCP) and maternal human platelet antigen (HPA) antibodies. Ninety four potential cases (91 pregnancies; three twin pregnancies) were registered between December 2004 and September 2015 with 76 confirmed or treated as NAIT. NAIT was frequently unanticipated (44 cases, 58%), whilst 32 cases (42%) were anticipated due to personal or family history. In 70/76 cases, the diagnosis of NAIT was made based on HPA antibody results; anti-HPA-1a was most commonly detected (58/70, 82%), followed by anti-HPA-5b (5/70, 7%). Intracranial haemorrhage (ICH) was detected in seven cases (9%). Maternal antenatal therapy resulted in improved clinical outcomes. For antenatally treated cases, whilst 10/29 (34%) neonates had severe TCP, only one ICH was detected. This study provides data on contemporary "real world" management of Australian mothers and babies with NAIT. Antenatal IVIG therapy was associated with better neonatal outcomes. Maternal side-effects and treatment costs were substantial.

    Background Health care quality is often linked to patient satisfaction. Yet, there is a lack of national studies examining the relationship between patient satisfaction, patient-reported outcomes, and medical expenditure. Objective The aim of this study is to examine the contribution of physical health, mental health, general health, and total health care expenditures to patient satisfaction using a longitudinal, nationally representative sample. Methods Using data from the 2010-2011 Medical Expenditure Panel Survey, analyses were conducted to predict patient satisfaction from patient-reported outcomes and total health care expenditures. The study sample consisted of adult participants (N=10,157), with sampling weights representative of 233.26 million people in the United States. Results The results indicated that patient-reported outcomes and total health care expenditure were associated with patient satisfaction such that higher physical and mental function, higher general health status, and higher total health care expenditure were associated with higher patient satisfaction. Conclusions We found that patient-reported outcomes and total health care expenditure had a significant relationship with patient satisfaction. As more emphasis is placed on health care value and quality, this area of research will become increasingly needed and critical questions should be asked about what we value in health care and whether we can find a balance between patient satisfaction, outcomes, and expenditures. Future research should apply big data analytics to investigate whether there is a differential effect of patient-reported outcomes and medical expenditures on patient satisfaction across different medical specialties.

    2017-03-01

    Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient's self-evaluation after the excision of the heterotopic ossification. This retrospective study assessed outcomes after excision of heterotopic ossification around the elbow in a cohort of ten patients operated from 2012 to 2015. The outcome assessment was done by the Mayo Elbow Performance index (MEPI) and the American Shoulder and Elbow Surgeons-Elbow score (ASES-E scores). The mean follow-up was 18.11 months after the operation. The Mayo Elbow Performance Score was excellent in two elbows, good in six and fair in two. The mean gain in flexion-extension arc after excision of HO was 80 degrees. All of the patients had residual flexion deformity postoperatively. Eight of the nine patients were able to do activities requiring flexion at final follow-up. Excision of HO around the elbow is associated with satisfactory patient-rated outcomes in spite of failure to regain full range of motion.

  17. Opinion dynamics with confirmation bias.

    Directory of Open Access Journals (Sweden)

    Armen E Allahverdyan

    Full Text Available Confirmation bias is the tendency to acquire or evaluate new information in a way that is consistent with one's preexisting beliefs. It is omnipresent in psychology, economics, and even scientific practices. Prior theoretical research of this phenomenon has mainly focused on its economic implications possibly missing its potential connections with broader notions of cognitive science.We formulate a (non-Bayesian model for revising subjective probabilistic opinion of a confirmationally-biased agent in the light of a persuasive opinion. The revision rule ensures that the agent does not react to persuasion that is either far from his current opinion or coincides with it. We demonstrate that the model accounts for the basic phenomenology of the social judgment theory, and allows to study various phenomena such as cognitive dissonance and boomerang effect. The model also displays the order of presentation effect-when consecutively exposed to two opinions, the preference is given to the last opinion (recency or the first opinion (primacy -and relates recency to confirmation bias. Finally, we study the model in the case of repeated persuasion and analyze its convergence properties.The standard Bayesian approach to probabilistic opinion revision is inadequate for describing the observed phenomenology of persuasion process. The simple non-Bayesian model proposed here does agree with this phenomenology and is capable of reproducing a spectrum of effects observed in psychology: primacy-recency phenomenon, boomerang effect and cognitive dissonance. We point out several limitations of the model that should motivate its future development.

    Cabot, Perry E; Nowak, Pete

    2005-01-01

    The paper explores how decisions made on animal feeding operations (AFOs) influence the management of manure and phosphorus. Variability among these decisions from operation to operation and from field to field can influence the validity of nutrient loss risk assessments. These assessments are based on assumptions that the decision outcomes regarding manure distribution will occur as they are planned. The discrepancy between planned versus actual outcomes in phosphorus management was explored on nine AFOs managing a contiguous set of 210 fields in south-central Wisconsin. A total of 2611 soil samples were collected and multiple interviews conducted to assign phosphorus index (PI) ratings to the fields. Spearman's rank correlation coefficients (r(S)) indicated that PI ratings were less sensitive to soil test phosphorus (STP) levels (r(S) = 0.378), universal soil loss equation (USLE) (r(S) = 0.261), ratings for chemical fertilizer application (r(S) = 0.185), and runoff class (r(S) = -0.089), and more sensitive to ratings for manure application (r(S) = 0.854). One-way ANOVA indicated that mean field STP levels were more homogenous than field PI ratings between AFOs. Kolmogorov-Smirnov (K-S) tests displayed several nonsignificant comparisons for cumulative distribution functions, S(x), of mean STP levels on AFO fields. On the other hand, the K-S tests of S(x) for PI ratings indicated that the majority of these S(x) functions were significantly different between AFOs at or greater than the 0.05 significance level. Interviews suggested multiple reasons for divergence between planned and actual outcomes in managing phosphorus, and that this divergence arises at the strategic, tactical, and operational levels of decision-making.

    Full Text Available BACKGROUND AND OBJECTIVES: Left ventricular mass (LVM is known to be related to overall and cardiovascular mortality in end stage kidney disease (ESKD patients. The aims of the present study are 1 to determine whether LVM is associated with mortality and various cardiovascular events and 2 to identify determinants of LVM including biomarkers of inflammation and fibrosis. DESIGN SETTING PARTICIPANTS & MEASUREMENTS: Analysis was performed with data of 327 ESKD patients, a subset from the CONvective TRAnsport STudy (CONTRAST. Echocardiography was performed at baseline. Cox regression analysis was used to assess the relation of LVM tertiles with clinical events. Multivariable linear regression models were used to identify factors associated with LVM. RESULTS: Median age was 65 (IQR: 54-73 years, 203 (61% were male and median LVM was 227 (IQR: 183-279 grams. The risk of all-cause mortality (hazard ratio (HR = 1.73, 95% CI: 1.11-2.99, cardiovascular death (HR = 3.66, 95% CI: 1.35-10.05 and sudden death (HR = 13.06; 95% CI: 6.60-107 was increased in the highest tertile (>260 grams of LVM. In the multivariable analysis positive relations with LVM were found for male gender (B = 38.8±10.3, residual renal function (B = 17.9±8.0, phosphate binder therapy (B = 16.9±8.5, and an inverse relation for a previous kidney transplantation (B = -41.1±7.6 and albumin (B = -2.9±1.1. Interleukin-6 (Il-6, high-sensitivity C-reactive protein (hsCRP, hepcidin-25 and connective tissue growth factor (CTGF were not related to LVM. CONCLUSION: We confirm the relation between a high LVM and outcome and expand the evidence for increased risk of sudden death. No relationship was found between LVM and markers of inflammation and fibrosis. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN38365125.

  3. Model confirmation in climate economics

    2016-01-01

    Benefit–cost integrated assessment models (BC-IAMs) inform climate policy debates by quantifying the trade-offs between alternative greenhouse gas abatement options. They achieve this by coupling simplified models of the climate system to models of the global economy and the costs and benefits of climate policy. Although these models have provided valuable qualitative insights into the sensitivity of policy trade-offs to different ethical and empirical assumptions, they are increasingly being used to inform the selection of policies in the real world. To the extent that BC-IAMs are used as inputs to policy selection, our confidence in their quantitative outputs must depend on the empirical validity of their modeling assumptions. We have a degree of confidence in climate models both because they have been tested on historical data in hindcasting experiments and because the physical principles they are based on have been empirically confirmed in closely related applications. By contrast, the economic components of BC-IAMs often rely on untestable scenarios, or on structural models that are comparatively untested on relevant time scales. Where possible, an approach to model confirmation similar to that used in climate science could help to build confidence in the economic components of BC-IAMs, or focus attention on which components might need refinement for policy applications. We illustrate the potential benefits of model confirmation exercises by performing a long-run hindcasting experiment with one of the leading BC-IAMs. We show that its model of long-run economic growth—one of its most important economic components—had questionable predictive power over the 20th century.

    Phase 3 icatibant trials showed that most hereditary angioedema (HAE) (C1 inhibitor deficiency) acute attacks were treated successfully with one injection of icatibant, a selective bradykinin B2 receptor antagonist. We conducted a post hoc analysis of icatibant reinjection for HAE type I and II attacks in a real-world setting by using data from the Icatibant Outcome Survey, an ongoing observational study that monitors the safety and effectiveness of icatibant treatment. Descriptive retrospective analyses of icatibant reinjection were performed on Icatibant Outcome Survey data (February 2008 to December 2012). New attacks were defined as the onset of new symptoms after full resolution of the previous attack. Potential associations between the patient and attack characteristics and reinjection were explored by using logistic regression analysis. Icatibant was administered for 652 attacks in 170 patients with HAE type I or II. Most attacks (89.1%) were treated with a single icatibant injection. For attacks that required two or three injections, the second injection was given a median of 11.0 hours after the first injection, with 90.4% of second injections administered ≥6 hours after the first injection. Time to resolution and attack duration were significantly longer for two or three injections versus one icatibant injection (p < 0.0001 and p < 0.05, respectively). Multivariate logistic regression analysis identified sex, attack severity, and laryngeal attacks as significantly correlated with reinjection (all p ≤ 0.05). These factors did not remain predictors for reinjection when two outlier patients with distinct patterns of icatibant use were excluded. In this real-world setting, most HAE attacks resolved with one icatibant injection. There was no distinct profile for patients or attacks that required reinjection when outliers with substantially different patterns of use were excluded. Because new attacks were not distinguished from the recurrence of symptoms

    To estimate the prevalence of untoward events during cataract surgery with the use of pupillary expansion devices and intraoperative floppy iris (IFIS). Retrospective analysis of 4923 cataract surgery cases from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project. Outcomes from 5 Veterans Affairs medical centers were analyzed, including use of alpha-blockers (both selective and nonselective), IFIS, intraoperative iris trauma, intraoperative iris prolapse, posterior capsular tear, anterior capsule tear, intraoperative vitreous prolapse, and use of pupillary expansion devices. P values were calculated using the χ(2) test. A total of 1254 patients (25.5%) took alpha-blockers preoperatively (selective, 587; nonselective, 627; both, 40). Of these 1254 patients, 428 patients (34.1%) had documented IFIS. However, 75.2% of patients with IFIS (428/569) had taken alpha-blockers preoperatively (P < .00001). A total of 430 patients (8.7%) had a pupillary expansion device used during their cataract surgery, of which 186 patients (43.4%) had IFIS (P < .0001). Eighty-six patients with IFIS had at least 1 intraoperative complication and 39 patients with IFIS had more than 1 intraoperative complication (P < .001). The use of either selective or nonselective alpha-antagonists preoperatively demonstrated a significant risk of IFIS. Nonselective alpha-antagonists caused IFIS at a higher prevalence than previously reported. This study did demonstrate statistically significant increased odds of surgical complications in patients with IFIS vs those without IFIS in all groups (those taking selective and nonselective alpha-antagonists and also those not taking medications).

    Growing evidence reveals various neighborhood conditions are associated with the risk of developing type 2 diabetes. It is unknown, however, whether the effectiveness of diabetes prevention interventions is also influenced by neighborhood characteristics. The purpose of the current study is to examine the impact of neighborhood characteristics on the outcomes of a lifestyle intervention to prevent diabetes in American Indians and Alaska Natives (AI/ANs). Year 2000 US Census Tract data were linked with those from the Special Diabetes Program for Indians Diabetes Prevention Program (SDPI-DP), an evidence-based lifestyle intervention implemented in 36 AI/AN grantee sites across the US. A total of 3394 participants started the intervention between 01/01/2006 and 07/31/2009 and were followed by 07/31/2016. In 2016-2017, data analyses were conducted to evaluate the relationships of neighborhood characteristics with intervention outcomes, controlling for individual level socioeconomic status. AI/ANs from sites located in neighborhoods with higher median household income had 38% lower risk of developing diabetes than those from sites with lower neighborhood income (adjusted hazard ratio = 0.65, 95% CI: 0.47-0.90). Further, those from sites with higher neighborhood concentrations of AI/ANs achieved less BMI reduction and physical activity increase. Meanwhile, participants from sites with higher neighborhood level of vehicle occupancy made more improvement in BMI and diet. Lifestyle intervention effectiveness was not optimal when the intervention was implemented at sites with disadvantaged neighborhood characteristics. Meaningful improvements in socioeconomic and other neighborhood disadvantages of vulnerable populations could be important in stemming the global epidemic of diabetes. Copyright © 2018 Elsevier Inc.

    This study evaluates the relevance of the tape position and change in shape (tape functionality) under in vivo conditions for mid-term outcome. Changes in the sonographic tension-free vaginal tape (TVT) position relative to the percentage urethral length and the tape-urethra distance were determined after 6 and 48 months in 41 women with stress urinary incontinence. At 48 months, 76% (31/41) of women were cured, 17% (7/41) were improved, and 7% (3/41) were failures. Disturbed bladder voiding was present in 12% (5/41), de novo urge incontinence in 7% (3/41). The median TVT position was at 63% of urethral length. Median tape-urethra distance was 2.7 mm, ranging from 2.9 mm in continent patients without complications to 1.1 mm in those with obstructive complications. Patients with postoperative urine loss had a median distance of 3.9 mm. The tape was stretched at rest and C-shaped during straining in 15 of 41 women (37%) at 48 months (all continent). Patients with this tape functionality at 6 months were also cured at 48 months in 86% of cases (19/22), and only 14% (3/22) showed recurrent incontinence. Mid-term data suggest an optimal outcome if the tape is positioned at least 2 mm from the urethra at the junction of the middle and distal thirds. Patients with optimal tape functionality at 6 months are likely to show mid-term therapeutic success.

    Background Kidney transplant recipients, like other patients with chronic kidney disease (CKD), experience excess risk of cardiovascular disease (CVD) and elevated total homocysteine (tHcy) concentrations. Observational studies of patients with CKD suggest increased homocysteine is a risk factor for CVD. The impact of lowering total homocysteine (tHcy) levels in kidney transplant recipients is unknown. Methods and Results In a double-blind controlled trial, we randomized 4110 stable kidney transplant recipients to a multivitamin that included either a high dose (n=2056) or low dose (n=2054) of folic acid, vitamin B6, and vitamin B12 to determine whether decreasing tHcy concentrations reduced the rate of the primary composite arteriosclerotic CVD outcome (myocardial infarction, stroke, CVD death, resuscitated sudden death, coronary artery or renal artery revascularization, lower extremity arterial disease, carotid endarterectomy or angioplasty, or abdominal aortic aneurysm repair). Mean follow-up was 4.0 years. Treatment with the high dose multivitamin reduced homocysteine but did not reduce the rates of the primary outcome (n= 547 total events; hazards ratio [95% confidence interval] = 0.99 [0.84–1.17]), or secondary outcomes of all-cause mortality (n=431 deaths; 1.04 [0.86–1.26]) or dialysis-dependent kidney failure (n=343 events; 1.15 [0.93–1.43]) compared to the low dose multivitamin. Conclusions Treatment with a high dose folic acid, B6, and B12 multivitamin in kidney transplant recipients did not reduce a composite cardiovascular disease outcome, all-cause mortality, or dialysis-dependent kidney failure despite significant reduction in homocysteine level.

    To compare obstetric and perinatal outcomes of Syrian refugee pregnants and Turkish counterparts who gave birth at a tertiary center in İstanbul. A retrospective study including the birth records of 704 Syrian refugees and 744 Turkish pregnant women between January 2016 and May 2017 were analyzed. Demographic data, obstetric and neonatal outcomes were compared. The primary aims of this study were to evaluate the pregnancy outcomes and cesarean rates between the groups. The secondary outcomes were the use of antenatal vitamin supplementation, hemoglobin-hematocrit values, and maternal complications. Our results showed that the use of folic acid and iron supplementation rates during pregnancy were similar between the groups (folic acid supplementation 8.1% vs 6.5%, p=0.264; iron supplementation 20.7% vs 19.6%, p=0.125; respectively for Turkish women and Syrian refugees). Cesarean rates were significantly higher for Turkish patients than in Syrian refugees (42.7% vs 32.7%; pyrian refugees (37.7±2.3 vs 36.4±2.3 weeks, pyrian refugees, respectively, p=0.105). Although obstetric complications were seen more often in Syrian refugees, it did not reach statistical difference (9.7% vs 8.1%, respectively, p=0.285). Syrian refugees use antenatal vitamin supplementations at similar rates to Turkish citizens and obstetric and perinatal outcomes are similar between the groups.

    Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy. Patients with Graves' disease were younger than MNG and thyroid cancer patients (M age  = 42.8 years vs. 55.5 and 51.0 years; p Graves' disease group included a higher proportion of women (p Graves' disease was independently associated with a higher risk of vocal-cord paralysis (odds ratio [OR] = 1.36 [confidence interval (CI) 1.08-1.69]), tracheostomy (OR = 1.35 [CI 1.1-1.67]), postoperative hypocalcemia (OR = 1.65 [CI 1.54-1.77]), and hematoma requiring reoperation (OR = 2.79 [CI 2.16-3.62]) compared to MNG patients. High-volume centers for total thyroidectomy were independently associated with lower risk of postoperative complications, including in patients with Graves' disease. Despite low overall morbidity following total thyroidectomy, Graves' disease patients are at increased risk of postoperative complications, including bleeding, vocal-cord paralysis, tracheostomy, and hypocalcemia. These risks appear

    The PROSPECT trial (N1048) is evaluating the selective use of chemoradiation in patients with cT2N1 and cT3N0-1 rectal cancer undergoing sphincter-sparing low anterior resection. We evaluated outcomes of PROSPECT-eligible and -ineligible patients from a multi-institutional database. Data from patients with locally advanced rectal cancer who received chemoradiation and low anterior resection from 2005 to 2014 were retrospectively collected from 5 Canadian centers. Overall survival, disease-free survival (DFS), recurrence-free survival (RFS), and time to local recurrence (LR) were estimated using the Kaplan-Meier method, and a multivariate analysis was performed adjusting for prognostic factors. A total of 566 (37%) of 1531 patients met the PROSPECT eligibility criteria. Eligible patients were more likely to have better PS (P = .0003) and negative circumferential resection margin (P PROSPECT eligibility was associated with improved DFS (hazard ratio [HR], 0.75; 95% confidence interval [CI], 0.61-0.91), overall survival (HR, 0.73; 95% CI, 0.57-0.95), and RFS (HR, 0.68; 95% CI, 0.54-0.86) in univariate analyses. In multivariate analysis, only RFS remained significantly improved for PROSPECT-eligible patients (HR, 0.75; 95% CI, 0.57-1.00, P = .0499). The 3-year DFS and freedom from LR for PROSPECT-eligible patients were 79.1% and 97.4%, respectively, compared to 71.1% and 96.8% for PROSPECT-ineligible patients. Real-world data corroborate the eligibility criteria used in the PROSPECT study; the criteria identify a subgroup of patients in whom risk of recurrence is lower and in whom selective use of chemoradiation should be actively examined.

    To determine the outcomes of Korean patients with fibromyalgia (FM) and to identify prognostic factors associated with improvement at 1-year follow-up. Forty-eight patients with FM were enrolled and examined every 3 months for 1 year. At the time of enrollment, we interviewed all patients using a structured questionnaire that recorded socio-demographic data, current or past FM symptoms, and current use of relevant medications. Tender point counts and scores were assessed by thumb palpation. Patients were asked to complete the Korean versions of the Fibromyalgia Impact Questionnaire (FIQ), the Brief Fatigue Inventory, the SF-36, the Beck Depression Inventory, the State-Trait Anxiety Inventory (STAI), the Self-Efficacy Scale, and the Social Support Scale. Tender points, FIQ scores, and the use of relevant medications were recorded during one year of follow-up. Of the 48 patients, 32 (66.7%) had improved FIQ scores 1 year after enrollment. Improved patients had higher baseline FIQ scores (68.4±13.9 vs. 48.4±20.8, p=0.001) and STAI-II scores (55.8±10.9 vs. 11.5±11.5, p=0.022). Patients treated with pregabalin were more likely to improve after 1 year, based on the FIQ scores (71.9% vs. 37.5%, p=0.031). On multivariate logistic regression analysis, a higher STAI-II score at the time of enrollment and pregabalin treatment during one year of follow-up were the predictors of improvement. Two-thirds of our Korean FM patients experienced some clinical improvement by 1-year follow-up. A high baseline STAI-II score and treatment with pregabalin were the important predictor of improved FM.

    In this article three research questions are addressed: (1) Is there an association between socioeconomic status (SES) and patient-reported outcomes in a cohort of multimorbid patients? (2) Does the association vary according to SES indicator used (income, education, occupational position)? (3) Can the association between SES and patient-reported outcomes (self-rated health, health-related quality of life and functional status) be (partly) explained by burden of disease? Analyses are based on the MultiCare Cohort Study, a German multicentre, prospective, observational cohort study of multimorbid patients from general practice. We analysed baseline data and data from the first follow-up after 15 months (N = 2,729). To assess burden of disease we used the patients' morbidity data from standardized general practitioner (GP) interviews based on a list of 46 groups of chronic conditions including the GP's severity rating of each chronic condition ranging from marginal to very severe. In the cross-sectional analyses SES was significantly associated with the patient-reported outcomes at baseline. Associations with income were more consistent and stronger than with education and occupational position. Associations were partly explained (17% to 44%) by burden of disease. In the longitudinal analyses only income (but not education and occupational position) was significantly related to the patient-reported outcomes at follow-up. Associations between income and the outcomes were reduced by 18% to 27% after adjustment for burden of disease. Results indicate social inequalities in self-rated health, functional status and health related quality of life among older multimorbid patients. As associations with education and occupational position were inconsistent, these inequalities were mainly due to income. Inequalities were partly explained by burden of disease. However, even among patients with a similar disease burden, those with a low income were worse off in terms of the

    Full Text Available The recently developed micropercutaneous nephrolithotomy (microperc is the miniaturized version of mini-percutaneous nephrolithotomy (PCNL and standard-PCNL that allows for safe access and stone disintegration under direct vision. In this single-centre study, the authors aimed to define the role of microperc in the management of renal calculi and analyse factors predicting outcomes. A total of 139 patients, who underwent microperc between June 2010 and November 2014, were enrolled in this study. Microperc was successful in 119 (91.53% patients, while in 11 patients (8.46% some residual fragments were seen on imaging. Of the total study group, conversion to mini- or standard PCNL was required in nine patients (6.47%. Overall complication rate of 11.53%, primarily minor complications comprising renal colic and urinary tract infection. On multivariate analysis, stone density (HU, stone number and stone volume were significantly associated with the dependent variable stone clearance. Multivariate analysis showed that intra-operative complications and stone number were significantly associated with conversion to mini- or standard PCNL. Stone volume threshold of 1.000 mm3 was a significant predictor of stone clearance in univariate and multivariate analyses, regardless of the stone location. Some limitations of this study, relatively small sample size and particularly the retrospective and non-comparative design, should be highlighted. EAU guidelines recommend shockwave lithotripsy (SWL or retrograde intrarenal surgery as the primary treatment modality for stones <10 mm in size. Although microperc is presently being used for small to moderate stones, the very indication that holds for SWL as well, it is notable that SWL is influenced by stone location and pelvicalyceal anatomy, and may require multiple sessions. Nevertheless, microperc has an inherent limitation in that the stone fragments cannot be retrieved for analysis. It has been noted that the

  1. Risk of Performance Decrements and Adverse Health Outcomes Resulting from Sleep Loss, Circadian Desynchronization, and Work Overload

    Sleep loss, circadian desynchronization, and work overload occur to some extent for ground and flight crews, prior to and during spaceflight missions. Ground evidence indicates that such risk factors may lead to performance decrements and adverse health outcomes, which could potentially compromise mission objectives. Efforts are needed to identify the environmental and mission conditions that interfere with sleep and circadian alignment, as well as individual differences in vulnerability and resiliency to sleep loss and circadian desynchronization. Specifically, this report highlights a collection of new evidence to better characterize the risk and reveals new gaps in this risk as follows: Sleep loss is apparent during spaceflight. Astronauts consistently average less sleep during spaceflight relative to on the ground. The causes of this sleep loss remain unknown, however ground-based evidence suggests that the sleep duration of astronauts is likely to lead to performance impairment and short and long-term health consequences. Further research is needed in this area in order to develop screening tools to assess individual astronaut sleep need in order to quantify the magnitude of sleep loss during spaceflight; current and planned efforts in BHP's research portfolio address this need. In addition, it is still unclear whether the conditions of spaceflight environment lead to sleep loss or whether other factors, such as work overload lead to the reduced sleep duration. Future data mining efforts and continued data collection on the ISS will help to further characterize factors contributing to sleep loss. Sleep inertia has not been evaluated during spaceflight. Ground-based studies confirm that it takes two to four hours to achieve optimal performance after waking from a sleep episode. Sleep inertia has been associated with increased accidents and reduced performance in operational environments. Sleep inertia poses considerable risk during spaceflight when emergency

    Full Text Available Awareness that maternal diet may influence the outcome of pregnancy as well as the long-term health of mother and child has increased in recent years. A new food frequency questionnaire (FFQ was developed and validated specifically for the Norwegian Mother and Child Cohort Study (MoBa. The MoBa FFQ is a semi-quantitative tool which covers the average intake of food, beverages and dietary supplements during the first 4 to 5 months of pregnancy. It includes questions about intakes of 255 foods and dishes and was used from 2002 onwards. Data assessed by the MoBa FFQ is available for 87,700 pregnancies. Numerous sub-studies have examined associations between dietary factors and health outcomes in MoBa. The aim of this paper is to summarize the results from 19 studies of maternal diet and pregnancy outcomes, which is the complete collection of studies based on the MoBa FFQ and published before September 2014. The overall research question is whether maternal diet – from single substances to dietary patterns – matters for pregnancy outcome. The pregnancy outcomes studied till now include birth size measures, infants being small and large for gestational age, pregnancy duration, preterm delivery, preeclampsia, as well as maternal gestational weight gain and postpartum weight retention. As a whole, the results from these studies corroborate that the current dietary recommendations to pregnant women are sound and that maternal diet during pregnancy is likely to contribute to reduce the risk of pregnancy complications including preterm birth, preeclampsia, and reduced foetal growth. The results provide supporting evidence for recommending pregnant women to consume vegetables, fruit, whole grain, fish, dairy, and water regularly and lower the intake of sugar sweetened beverages, processed meat products and salty snacks. The results showing negative impact of even low levels of environmental contaminants support the precautionary advice on consumption

    Fibromyalgia is associated with substantial functional disability. Current drug and non-drug treatments result in statistically significant but numerically small improvements in typical numeric measures of pain severity and fibromyalgia impact. The aim of the present study was to evaluate additional measures of pain severity and functional outcome that might be affected by fibromyalgia treatment. This retrospective review evaluated outcomes from 274 adults with fibromyalgia who participated in a six-week, multidisciplinary treatment programme. Pain and function were evaluated on the first and final treatment visit. Pain was evaluated using an 11-point numerical scale to determine clinically meaningful pain reduction (decrease ≥ 2 points) and from a pain drawing. Function was evaluated by measuring active range of motion (ROM), walking distance and speed, upper extremity exercise repetitions, and self-reports of daily activities. Numerical rating scores for pain decreased by 10-13% (p Fibromyalgia Impact Questionnaire (FIQ) scores decreased by 20% (p fibromyalgia treatment effectiveness. © 2013 John Wiley & Sons, Ltd.

    Background Bariatric surgery is one of the few effective treatments for morbid obesity but the weight loss and other health related outcomes for this procedure in large, diverse adolescent patient populations are not well characterized. Objective To analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. Setting BOLD data is collected from 423 surgeons at 360 facilities in the United States. Methods Main outcome measures included anthropometric and comorbidity status at baseline (n=890) and at 3 (n=786), 6 (n=541), and 12 (n=259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) age 11-to-19 years were included in the analyses. Results The overall one year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 kg versus 20 kg, Psurgery types (Psurgery. There were a total of 45 readmissions among gastric bypass patients and 10 among adjustable gastric band patients with 29 and 8 reoperations required, respectively. Conclusions Weight loss at 3-, 6-, and 12-months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related comorbidities in morbidly obese adolescents for at least 1 year. PMID:22542199

    Full Text Available Background. A variety of symptoms have been reported, but the prevalence of specific symptoms in relapsing-remitting multiple sclerosis (RRMS, how they are related to one another, and their impact on patient reported outcomes is not well understood. Objective. To describe how symptoms of RRMS cooccur and their impact on patient-reported outcomes. Methods. Individuals who reported a physician diagnosis of RRMS in a large general health survey in the United States indicated the symptoms they experience because of RRMS and completed validated scales, including the work productivity and activity impairment questionnaire and either the SF-12v2 or SF-36v2. Symptom clusters were identified through hierarchical cluster analysis, and the relationship between clusters and outcomes was assessed through regression. Results. Fatigue, difficulty walking, and numbness were the most commonly reported symptoms. Seven symptom clusters were identified, and several were significantly related to patient reported outcomes. Pain, muscle spasms, and stiffness formed a cluster strongly related to physical quality of life; depression was strongly related to mental quality of life and cognitive difficulty was associated with work impairment. Conclusions. Symptoms in RRMS show a strong relationship with quality of life and should be taken into consideration in treatment decisions and evaluation of treatment success.

    The aim of this study was to compare audiometric results before and after stapes surgery and identify potential prognostic factors to appropriately select patients with otosclerosis who will most likely benefit from surgery. We enrolled 126 patients with otosclerosis (162 consecutive ears) in our study who underwent stapes surgery between 2007 and 2012 at our institution. Preoperative and postoperative data including pure-tone audiometry, speech audiometry, stapedial reflex audiometry and surgical data were analyzed. The average preoperative air-bone gap (ABG) was 28.9 ± 8.6 dB. Male patients and patients older than 45 years of age had greater preoperative ABGs in comparison to females and younger patients. Postoperative ABGs were 11.2 ± 7.4 dB. The average ABG gain was 17.7 ± 11.1 dB. Preoperative audiometric data, age, gender and type of surgery did not influence the postoperative results. Stapes surgery offers predictable results independent from disease progression or patient-related factors. While absolute values of hearing improvement are instrumental in reflecting audiometric results of a cohort, relative values better reflect individual's audiometric data resembling the patient's benefit.

    Few data are available regarding the long-term psychological impact of uninformative BRCA1/2 test results. This study examines change in distress from pretesting to 12-months post-disclosure, with medical, family history, and psychological variables, such as pretesting perceived risk of carrying a deleterious mutation prior to testing and primary and secondary appraisals, as predictors. Two hundred and nine women with uninformative BRCA1/2 test results completed questionnaires at pretesting and 1-, 6-, and 12-month post-disclosure, including measures of anxiety and depression, cancer-specific and genetic testing distress. We used a mixed models approach to predict change in post-disclosure distress. Distress declined from pretesting to 1-month post-disclosure, but remained stable thereafter. Primary appraisals predicted all types of distress at 1-month post-disclosure. Primary and secondary appraisals predicted genetic testing distress at 1-month as well as change over time. Receiving a variant of uncertain clinical significance and entering testing with a high expectation for carrying a deleterious mutation predicted genetic testing distress that persisted through the year after testing. As a whole, women receiving uninformative BRCA1/2 test results are a resilient group. For some women, distress experienced in the month after testing does not dissipate. Variables, such as heightened pretesting perceived risk and cognitive appraisals, predict greater likelihood for sustained distress in this group and could be amenable to intervention.

Of these, 428 objects previously identified as candidates were found to have FPP of more than 90%, suggesting that they are most likely false positives.Periods and radii of candidate and confirmed planets in the Kepler Objects of Interest catalog. Blue circles have previously been identified as confirmed planets. Candidates (orange) are shaded by false positive probability; more transparent means more likely to be a false positive. [Morton et al. 2016]In contrast, 1,935 candidates were found to have FPP of less than 1%, and were therefore declared validated planets. Of these confirmations, 1,284 were previously unconfirmed, more than doubling Keplers previous catalog of 1,041 confirmed planets. Morton and collaborators believe that 9 of these newly confirmed planets may fall within the habitable zone of their host stars.While the announcement of 1,284 newly confirmed planets is huge, the analysis presented in this study is the real news. The code used is publicly available and can be applied to any transiting exoplanet candidate. This means that this analysis technique can be used to find batches of exoplanets in data from the extended Kepler mission (K2) or from the future TESS and PLATO transit missions.CitationTimothy D.

    Purpose: We updated our previous report of a phase 2 trial using proton beam radiation therapy to deliver partial breast irradiation (PBI) in patients with early stage breast cancer. Methods and Materials: Eligible subjects had invasive nonlobular carcinoma with a maximal dimension of 3 cm. Patients underwent partial mastectomy with negative margins; axillary lymph nodes were negative on sampling. Subjects received postoperative proton beam radiation therapy to the surgical bed. The dose delivered was 40 Gy in 10 fractions, once daily over 2 weeks. Multiple fields were treated daily, and skin-sparing techniques were used. Following treatment, patients were evaluated with clinical assessments and annual mammograms to monitor toxicity, tumor recurrence, and cosmesis. Results: One hundred subjects were enrolled and treated. All patients completed the assigned treatment and were available for post-treatment analysis. The median follow-up was 60 months. Patients had a mean age of 63 years; 90% had ductal histology; the average tumor size was 1.3 cm. Actuarial data at 5 years included ipsilateral breast tumor recurrence-free survival of 97% (95% confidence interval: 100%-93%); disease-free survival of 94%; and overall survival of 95%. There were no cases of grade 3 or higher acute skin reactions, and late skin reactions included 7 cases of grade 1 telangiectasia. Patient- and physician-reported cosmesis was good to excellent in 90% of responses, was not changed from baseline measurements, and was well maintained throughout the entire 5-year follow-up period. Conclusions: Proton beam radiation therapy for PBI produced excellent ipsilateral breast recurrence-free survival with minimal toxicity. The treatment proved to be adaptable to all breast sizes and lumpectomy cavity configurations. Cosmetic results appear to be excellent and unchanged from baseline out to 5 years following treatment. Cosmetic results may be improved over those reported with photon

    Previous randomized controlled trials have demonstrated that partial fundoplication following Heller myotomy results in less pathologic acid exposure to the esophagus when compared to myotomy without fundoplication. Recent studies have questioned the necessity of a fundoplication, especially when a limited hiatal dissection (LHD) is performed and the angle of His is preserved. This is a retrospective review of prospectively maintained data. All patients underwent primary Heller myotomy for achalasia over a 30-month period. In select patients, an LHD was performed anteriorly. Symptomatic outcomes were assessed up to 2 years postoperation using the Achalasia Severity Questionnaire (ASQ), Gastrointestinal Quality of Life Index (GIQLI), and Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL). A total of 31 patients underwent Heller myotomy during the study interval. The majority of patients underwent Heller myotomy with full hiatal dissection (FHD) (21, 68%). Intraoperative mucosal perforations occurred in 3 (14%) patients undergoing FHD. Patient demographics, surgery details, and baseline symptomatic outcomes did not differ significantly preoperatively. At greater than 1 year postoperation, there was no significant difference between the groups for ASQ, GERD-HRQL, and GIGLI (P = .76, .78, and .33, respectively). Heller myotomy with LHD and no fundoplication and Heller myotomy with FHD and partial fundoplication result in similar GERD-related quality of life outcomes. Further studies (including pH studies) are necessary to determine if fundoplication is a necessary step in selected patients in whom an LHD is possible.

    Objective: To demonstrate lower limb angiography results of peripheral arterial disease (PAD) in diabetics and evaluate one-year curative effect after interventional therapy. Methods: Lower limb angiography results and the efficiency of interventional therapy for 44 limbs with PAD in 38 diabetics were retrospectively analyzed. Post-treatment clinical manifestations, signs and ankle-brachial-index (ABI) at 1 week, 1 month, 3 months, 6 months and 12 months were compared with those before treatment. Clinical evaluation was divided into four grades: apparent, effective, ineffective and deterioration. Efficiency = (apparent + effective) / total cases × 100%. ABI was compared using analysis of variance. Results: Lower limb angiography revealed multi-branch lesions, with multi-segmental stenoses or obstructions. Lesions involved both above- and below-the-knee arteries in 25 limbs (56.8%), only above-the-knee arteries in 3 limbs (6.8%) and only below-the-knee arteries in 16 limbs (36.4%). In the limbs only with below-the-knee arterial lesions, the involved artery branches were one in one limb (2.3%), two in six limbs (13.6%) and three in nine limbs (20.5%), respectively. The technical success rate of percutaneous transluminal angioplasty (PTA) was 91.4% (53/58) for diseased below-the-knee arteries. Among the 12 cases with foot and ankle ulcers, ulcers healed within 3 months in 9 cases; however, the other three cases suffered below-the-ankle (in one case) or below-the-knee amputation (in two cases) within 6 months. Four cases with gangrene suffered below-the-knee amputation within one month after PTA. The amputation rate was 15.9% (7/44). At 1 week, 1, 3, 6 and 12 months after PTA, the effective rates were 79.6% (35/44), 83.3% (30/36), 85.7% (24/28), 85.0% (17/20) and 81.3% (13/16), respectively; ABI values were 0.86±0.10, 0.85±0.10, 0.83±0.11, 0.79±0.12 and 0.75±0.12, respectively. Compared with pie-PTA ABI value (0.53±0.20), post-PTA ABI value was significant

    Purpose: To correlate tumor oxygenation status with long-term biochemical outcome after prostate brachytherapy. Methods and Materials: Custom-made Eppendorf PO 2 microelectrodes were used to obtain PO 2 measurements from the prostate (P), focused on positive biopsy locations, and normal muscle tissue (M), as a control. A total of 11,516 measurements were obtained in 57 men with localized prostate cancer immediately before prostate brachytherapy was given. The Eppendorf histograms provided the median PO 2 , mean PO 2 , and % 2 ratio on BF. Results: With a median follow-up time of 8 years, 12 men had ASTRO BF and 8 had Phoenix BF. On multivariate analysis, P/M PO 2 ratio 2 ratio 2 ratio) significantly predicts for poor long-term biochemical outcome, suggesting that novel hypoxic strategies should be investigated.

    Clinicians often assert that disclosure of childhood rape is beneficial to victims because it sets the occasion for protective action and can bring them into contact with professionals trained to address rape-related mental health needs. Consistent with this is the hypothesis that victims of childhood rape who disclose their victimization soon after it occurs are at lower risk for later psychosocial difficulties relative to those who delay disclosure or never disclose. We explored this issue with a nationally representative sample of 3,220 adult women; 288 (8.9%) endorsed at least one instance of forcible sexual penetration prior to age 18. Results revealed a significantly higher past-year prevalence of posttraumatic stress disorder (PTSD) and major depressive episodes among women who waited longer than 1 month to disclose their rape relative to nondisclosers and women who disclosed within 1 month of the rape. Delayed disclosure remained associated with PTSD after controlling for demographic and rape characteristics. Patterns of disclosure were not associated with past-year substance-use problems.

    Purpose: Three-dimensional conformal radiotherapy (3D-CRT) has been associated with a reduction in acute and late toxicity among patients treated for localized prostatic cancer. The purpose of this study is to assess the acute and late toxicity of 3D-CRT delivered to patients in the postprostatectomy setting and to analyze which factors predict for durable biochemical control in this group of patients. Methods and Materials: Between 1988 and 1994, 42 patients were treated after prostatectomy with three-dimensional conformal radiotherapy. The median time from prostatectomy to radiotherapy was 11 months. Indications for treatment included a rising serum PSA level in 28 patients (65%) and positive surgical margins without a rising PSA level in 14 (35%). Twenty-five patients (60%) had pathologic stage T3 disease, and 32 (74%) had tumor at or close to the surgical margins. The median dose was 64.8 Gy, and the median follow-up time was 2 years. Results: 3D-CRT in the postprostatectomy setting was well tolerated. Three patients (7%) experienced Grade II acute genitourinary toxicity and nine patients (21%) experienced Grade II acute gastrointestinal toxicity during treatment. No patient experienced Grade III or higher acute morbidity. The 2-year actuarial risk for Grade II late genitourinary and gastrointestinal late complications were 5 and 9%, respectively. In patients with existing incontinence, the incidence of worsening stress incontinence 6 months after treatment was 17%, which resolved within 12 months to its preradiotherapy level in four of six cases (66%). The overall 2-year postirradiation PSA relapse-free survival rate was 53%. The 2-year PSA relapse-free survival was 66% for patients with undetectable PSA levels in the immediate postoperative period compared to 26% for those with detectable levels of PSA after surgery (p 1.0 ng/ml (p 1 ng/ml (p < 0.002) was the most important covariate predicting for a rising PSA after radiotherapy. Conclusions: After

    Purpose: To describe brain CT findings in retinopathy-confirmed, paediatric cerebral malaria. Materials and methods: In this outcomes study of paediatric cerebral malaria, a subset of children with protracted coma during initial presentation was scanned acutely. Survivors experiencing adverse neurological outcomes also underwent a head CT. All children had ophthalmological examination to confirm the presence of the retinopathy specific for cerebral malaria. Independent interpretation of CT images was provided by two neuroradiologists. Results: Acute brain CT findings in three children included diffuse oedema with obstructive hydrocephalus (2), acute cerebral infarctions in multiple large vessel distributions with secondary oedema and herniation (1), and oedema of thalamic grey matter (1). One child who was reportedly normal prior to admission had parenchymal atrophy suggestive of pre-existing CNS injury. Among 56 survivors (9-84 months old), 15 had adverse neurologic outcomes-11/15 had a follow-up head CT, 3/15 died and 1/15 refused CT. Follow-up head CTs obtained 7-18 months after the acute infection revealed focal and multifocal lobar atrophy correlating to regions affected by focal seizures during the acute infection (5/11). Other findings were communicating hydrocephalus (2/11), vermian atrophy (1/11) and normal studies (3/11). Conclusions: The identification of pre-existing imaging abnormalities in acute cerebral malaria suggests that population-based studies are required to establish the rate and nature of incidental imaging abnormalities in Malawi. Children with focal seizures during acute cerebral malaria developed focal cortical atrophy in these regions at follow-up. Longitudinal studies are needed to further elucidate mechanisms of CNS injury and death in this common fatal disease.

    Full Text Available Objective: Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment. Methods: 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8% attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators. Results: Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19 compared to those presenting moderate (Δ BMI-SDS -0.14 and high social risk (Δ BMI-SDS -0.11. Conclusion: Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents.

    Full Text Available Background: The transosseous-equivalent cross bridge double row (TESBDR rotator cuff (RC repair technique has been developed to optimize healing biology at a repaired RC tendon insertion. It has been shown in the laboratory to improve pressurized contact area and mean foot print pressure when compared with a double row anchor technique. Pressure has been shown to influence healing between tendon and bone, and the tendon compression vector provided by the transosseous-equivalent suture bridges may enhance healing. The purpose was to prospectively evaluate the outcomes of arthroscopic TESBDR RC repair. Methods: Single center prospective case series study. Sixty-nine patients were selected to undergo arthroscopic TESBDR RC repair and were included in the current study. Primary outcome measures included the Oxford Shoulder Score (OSS, the University of California, Los Angeles (UCLA score, the Constant-Murley (CM Score and Range of motion (ROM. Secondary outcome measures included a Visual Analogue Scale (VAS for pain, another VAS for patient satisfaction from the operative procedure, EuroQoL 5-Dimensions Questionnaire (EQ-5D for quality of life assessment. Results: At 24 months post-operative, average OSS score was 44, average UCLA score was 31, average CM score was 88, average forward flexion was 145°, average internal rotation was 35°, average external rotation was 79°, average abduction was 150°, average EQ-5D score was 0.73, average VAS for pain was 2.3, and average VAS for patient satisfaction was 9.2. Conclusion: Arthroscopic TESBDR RC repair is a procedure with good post-operative functional outcome and low re-tear rate based on a short term follow-up.

    When NASA's Lunar Crater Observation and Sensing Satellite (LCROSS) and a companion rocket purposely slammed into a crater at the Moon's south pole on 9 October, some observers on Earth lamented as anticlimactic the raised plumes of material that were partially blocked by a crater ridge and were difficult to see with backyard telescopes. However, it turns out that the projectiles struck it big. “Indeed, yes, we found water. We didn’t find just a little bit; we found a significant amount,” said Anthony Colaprete, LCROSS principal investigator with the NASA Ames Research Center, Moffett Field, Calif. At a 13 November news briefing, Colaprete lifted a 2-gallon plastic bucket and said preliminary results indicate that instruments detected about a dozen buckets' worth of water in parts of the two plumes, the first generated by the spent Centaur upper stage of the Atlas V launch vehicle at 1131 UTC and the second generated by LCROSS about 4 minutes later. NASA described the two plumes as a high-angle plume of vapor and fine dust and a lower-angle ejecta curtain of heavier material. LCROSS and the Centaur upper stage hit the permanently shadowed Cabeus crater.

    Full Text Available Introduction. Intertrochanteric hip fractures occur in the proximal femur. They are very common in the elderly and are responsible for high rates of morbidity and mortality. The authors hypothesized that adding an autologous bone marrow stem cells concentrate (ABMC to a hydroxyapatite scaffold and placing it in the fracture site would improve the outcome after surgical fixation of intertrochanteric hip fractures. Material and Methods. 30 patients were randomly selected and divided into 2 groups of 15 patients, to receive either the scaffold enriched with the ABMC (Group A during the surgical procedure, or fracture fixation alone (Group B. Results. There was a statistically significant difference in favor of group A at days 30, 60, and 90 for Harris Hip Scores (HHS, at days 30 and 60 for VAS pain scales, for bedridden period and time taken to start partial and total weight bearing (P<0.05. Discussion. These results show a significant benefit of adding a bone marrow enriched scaffold to surgical fixation in intertrochanteric hip fractures, which can significantly reduce the associated morbidity and mortality rates.

    Full Text Available OBJECTIVES: Publication bias may affect the validity of evidence based medical decisions. The aim of this study is to assess whether research outcomes affect the dissemination of clinical trial findings, in terms of rate, time to publication, and impact factor of journal publications. METHODS AND FINDINGS: All drug-evaluating clinical trials submitted to and approved by a general hospital ethics committee between 1997 and 2004 were prospectively followed to analyze their fate and publication. Published articles were identified by searching Pubmed and other electronic databases. Clinical study final reports submitted to the ethics committee, final reports synopses available online and meeting abstracts were also considered as sources of study results. Study outcomes were classified as positive (when statistical significance favoring experimental drug was achieved, negative (when no statistical significance was achieved or it favored control drug and descriptive (for non-controlled studies. Time to publication was defined as time from study closure to publication. A survival analysis was performed using a Cox regression model to analyze time to publication. Journal impact factors of identified publications were recorded. Publication rate was 48·4% (380/785. Study results were identified for 68·9% of all completed clinical trials (541/785. Publication rate was 84·9% (180/212 for studies with results classified as positive and 68·9% (128/186 for studies with results classified as negative (p<0·001.

    Evidence from both animal and human studies suggests that exposure to phthalates may be associated with adverse female reproductive outcomes. We evaluated the associations between urinary concentrations of phthalate metabolites and outcomes of assisted reproductive technologies (ART). This analysis included 256 women enrolled in the Environment and Reproductive Health (EARTH) prospective cohort study (2004-2012) who provided one to two urine samples per cycle before oocyte retrieval. We measured 11 urinary phthalate metabolites [mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), mono(2-ethyl-5-oxohexyl) phthalate (MEOHP), mono(2-ethyl-5-carboxypentyl) phthalate (MECPP), mono-isobutyl phthalate (MiBP), mono-n-butyl phthalate (MBP), monobenzyl phthalate (MBzP), monoethyl phthalate (MEP), monocarboxyisooctyl phthalate (MCOP), monocarboxyisononyl phthalate (MCNP), and mono(3-carboxypropyl) phthalate (MCPP)]. We used generalized linear mixed models to evaluate the association of urinary phthalate metabolites with in vitro fertilization (IVF) outcomes, accounting for multiple IVF cycles per woman. In multivariate models, women in the highest as compared with lowest quartile of MEHP, MEHHP, MEOHP, MECPP, ΣDEHP (MEHP + MEHHP + MEOHP + MECPP), and MCNP had lower oocyte yield. Similarly, the number of mature (MII) oocytes retrieved was lower in the highest versus lowest quartile for these same phthalate metabolites. The adjusted differences (95% CI) in proportion of cycles resulting in clinical pregnancy and live birth between women in the fourth versus first quartile of ΣDEHP were -0.19 (-0.29, -0.08) and -0.19 (-0.28, -0.08), respectively, and there was also a lower proportion of cycles resulting in clinical pregnancy and live birth for individual DEHP metabolites. Urinary concentrations of DEHP metabolites were inversely associated with oocyte yield, clinical pregnancy, and live birth following ART. Hauser R, Gaskins AJ, Souter I, Smith

    In cancers of the distal rectum, preoperative radiotherapy is often associated with low anterior resection. This study assesses the choice of surgical procedure, oncological results, and quality of life outcomes in a retrospective cohort of patients with low-lying rectal cancers. The results obtained reinforce the notion of the feasibility, in routine practice, of sphincter-sparing surgery after preoperative radiotherapy in a significant proportion of low rectal cancers. The oncological results seem to be unaffected by the choice of surgical procedure. However, with the possible exception of body image and sexual aspects in males, quality of life parameters were not necessarily better in the restorative surgery group. Prospective studies are mandatory to clarify the putative quality of life advantages of sphincter-conserving procedures in this context. (author)

    There is a paucity of evidence guiding management of small area partial thickness paediatric scalds. This has prevented the development of national management guidelines for these injuries. This research aimed to investigate whether a lack of evidence for national guidelines has resulted in variations in both management and outcomes of paediatric small area scalds across England and Wales (E&W). A national survey of initial management of paediatric scalds ≤5% Total Body Surface Area (%TBSA) was sent to 14 burns services in E&W. Skin graft rates of anonymised burns services over seven years were collected from the international Burns Injury Database (iBID). Average skin grafting rates across services were compared. Length of stay and proportion of patients receiving general anaesthesia for dressing application at each service were also compared. All 14 burns services responded to the survey. Only 50% of services had a protocol in place for the management of small area burns. All protocols varied in how partial thickness paediatrics scalds ≤5% TBSA should be managed. There was no consensus as to which scalds should be treated using biosynthetic dressings. Data from iBID for 11,917 patients showed that the average reported skin grafting rate across all burns services was 2.3% (95% CI 2.1, 2.6) but varied from 0.3% to 7.1% (P<0.001). Service provider remained associated with likelihood of skin grafting when variations in the %TBSA case mix seen by each service were controlled for (χ(2)=87.3, P<0.001). The use of general anaesthetics across services varied between 0.6 and 35.5% (P<0.001). The median length of stay across services varied from 1 to 3 days (P<0.001). A lack of evidence guiding management of small-area paediatric scalds has resulted in variation in management of these injuries across E&W. There is also significant variation in outcomes for these injuries. Further research is indicated to determine if care pathways and outcomes are linked. An evidence

    Full Text Available The purpose of this prospective multicentric observational study was to confirm the safety and clinical performance of a craniocaudal expandable implant used in combination with high viscosity PMMA bone cement for the treatment of vertebral compression fractures. Thirty-nine VCFs in 32 patients were treated using the SpineJack minimally invasive surgery protocol. Outcome was determined by using the Visual Analogue Scale for measuring pain, the Oswestry Disability Index for scoring functional capacity, and the self-reporting European Quality of Life scores for the quality of life. Safety was evaluated by reporting all adverse events. The occurrence of cement leakages was assessed by either radiographs or CT scan or both. Statistically significant improvements were found regarding pain, function, and quality of life. The global pain score reduction at 1 year was 80.9% compared to the preoperative situation and the result of the Oswestry Disability Index showed a decrease from 65.0% at baseline to 10.5% at 12 months postoperatively. The cement leakage rate was 30.8%. No device- or surgery-related complications were found. This observational study demonstrates promising and persistent results consisting of immediate and sustained pain relief and durable clinical improvement after the procedure and throughout the 1-year follow-up period.

    A substantial number of patients do not benefit from first line psychological therapies for the treatment of depression and anxiety. Currently, there are no clear predictors of treatment outcomes for these patients. The PROMPT project aims to establish an infrastructure platform for the identification of factors that predict outcomes following psychological treatment for depression and anxiety. Here we report on the first year of recruitment and describe the characteristics of our sample to date. One hundred and forty-seven patients awaiting treatment within an Improving Access to Psychological Therapies (IAPT) service were recruited between February 2014 and February 2015 (representing 48 % of those eligible). Baseline assessments were conducted to collect information on a variety of clinical, psychological and social variables including a diagnostic interview using the Mini International Neuropsychiatric Interview (MINI). Our initial findings showed that over a third of our sample were not presenting to IAPT services for the first time, and 63 % had been allocated to receive higher intensity IAPT treatments. Approximately half (46 %) were taking prescribed psychotropic medication (most frequently antidepressants). Co-morbidity was common: 72 % of the sample met criteria for 2 or more current MINI diagnoses. Our initial data also indicated that 16 % met criteria for borderline personality disorder and 69 % were at high risk of personality disorder. Sixty-one percent scored above the screening threshold for bipolarity. Over half of participants (55 %) reported experiencing at least one stressful life event in the previous 12 months, whilst 67 % reported experiencing at least one form of childhood trauma. Our results to date highlight the complex nature of patients seen within an urban IAPT service, with high rates of psychiatric comorbidity, personality disorder, bipolarity and childhood trauma. Whilst there are significant challenges associated with researching

    Full Text Available Abstract Background Bacterial vaginosis (BV during pregnancy is associated with an increased risk of preterm delivery but little is known about factors that could predict BV. We have analyzed if it is possible to identify a category of pregnant women that should be screened for BV, and if BV would alter the pregnancy outcome at term; we have also studied the treatment efficacy of clindamycin. Methods Prospective BV screening and treatment study of 9025 women in a geographically defined region in southeast Sweden. BV was defined as a modified Nugent score of 6 and above. Data was collected from the Swedish Medical Birth Register. Women allocated to treatment were supplied with vaginal clindamycin cream. The main outcome goals were to identify factors that could predict BV. Results Vaginal smears were consistent with BV criteria in 9.3%. Logistic regression indicates a significant correlation between smoking and BV (p Conclusion BV is more than twice as common among smokers, and there is a higher prevalence in the younger age group. However these two markers for BV do not suffice as a tool for screening, and considering the lack of other risk factors associated with BV, screening of all pregnant women might be a strategy to follow in a program intended to reduce the number of preterm births.

    Full Text Available Background: Young maternal age is variously defined in studies of its effect on obstetrics and perinatal outcomes. Also, pregnancy has been reported as the leading cause of death in adolescent girls in low- and middle-income countries. Aims: The aim of the study was to evaluate whether young maternal age was associated with an increased risk of obstetrics and perinatal adverse outcomes. Study Design: Case-control study. Methods: This case-control study was derived from a database of the medical records between January 2008 and December 2012. In the present study, 1374 teenage pregnancy and 1294 adult pregnancy cases were included. After restriction of analyses to singleton primiparous women, 1282 teenage pregnancy and 735 adult pregnancy cases were analyzed. Maternal age was separated into three groups: 15 and less, 16-19, and 20-34 years. Adjusted odds ratios (ORs were derived through logistic regression models for the potential confounding factors. Results: Adolescents aged 15 years and younger had higher risks of preterm delivery, early preterm delivery, intrauterine fetal death and neonatal death compared with women aged 20 to 34 years after adjustment for confounding factors. In addition, both groups of adolescents had higher risks for anemia and episiotomy and lower risk of cesarean delivery. The rates of preeclampsia, gestational diabetes, chronic diseases, intrauterine growth restriction (IUGR were higher in the adult group. Conclusion: Younger maternal age was correlated with increased risks of preterm delivery, fetal and neonatal death and anemia.

    To empirically classify phenotypes of eating disorders (ED) using latent class analysis (LCA), and to validate this classification based on clinical outcomes. LCA was applied to 968 inpatients. The resultant classes were validated by clinical outcomes including mortality. A 5-class solution showed the best fit. The symptoms of latent class 1 (LC1; 26% of the sample) resembled anorexia nervosa (AN), bingeing-purging (AN-B/P) subtype; those of LC2 (23%) resembled bulimia nervosa; those of LC3 (11%) were close to AN-B/P without weight and body concerns; those of LC4 resembled restrictive anorexia nervosa (RAN) without weight and body concerns, and those of LC5 RAN. A history of hospitalization for ED was significantly more frequent for LC3 and LC4. The lowest BMI at admission were presented in LC4. LC1 showed the highest level of psychological disturbances and LC4 the lowest. LC3 and LC4 differed from LC1 and LC5 by higher percentages of treatment dropout (64.9 vs. 57.2 and 55.7 vs. 47.5%, respectively; overall p = 0.001). Survival rates tended to be different between the LC (p = 0.09). Subgroups of AN patients with low weight and body concerns seem more severe at hospitalization and more difficult to manage, with a higher rate of treatment dropout than the 'typical' AN patients.

    Full Text Available Abstract Background To report acute toxicity, initial outcome results and planning therapeutic parameters in radiation treatment of advanced lung cancer (stage III with volumetric modulated arcs using RapidArc (RA. Methods Twenty-four consecutive patients were treated with RA. All showed locally advanced non-small cell lung cancer with stage IIIA-IIIB and with large volumes (GTV:299 ± 175 cm3, PTV:818 ± 206 cm3. Dose prescription was 66Gy in 33 fractions to mean PTV. Delivery was performed with two partial arcs with a 6 MV photon beam. Results From a dosimetric point of view, RA allowed us to respect most planning objectives on target volumes and organs at risk. In particular: for GTV D1% = 105.6 ± 1.7%, D99% = 96.7 ± 1.8%, D5%-D95% = 6.3 ± 1.4%; contra-lateral lung mean dose resulted in 13.7 ± 3.9Gy, for spinal cord D1% = 39.5 ± 4.0Gy, for heart V45Gy = 9.0 ± 7.0Gy, for esophagus D1% = 67.4 ± 2.2Gy. Delivery time was 133 ± 7s. At three months partial remission > 50% was observed in 56% of patients. Acute toxicities at 3 months showed 91% with grade 1 and 9% with grade 2 esophageal toxicity; 18% presented grade 1 and 9% with grade 2 pneumonia; no grade 3 acute toxicity was observed. The short follow-up does not allow assessment of local control and progression free survival. Conclusions RA proved to be a safe and advantageous treatment modality for NSCLC with large volumes. Long term observation of patients is needed to assess outcome and late toxicity.

    The objective of this study has been to confirm the sex and the affinity of an individual buried in a well-furnished warrior grave (Bj 581) in the Viking Age town of Birka, Sweden. Previously, based on the material and historical records, the male sex has been associated with the gender of the warrior and such was the case with Bj 581. An earlier osteological classification of the individual as female was considered controversial in a historical and archaeological context. A genomic confirmation of the biological sex of the individual was considered necessary to solve the issue. Genome-wide sequence data was generated in order to confirm the biological sex, to support skeletal integrity, and to investigate the genetic relationship of the individual to ancient individuals as well as modern-day groups. Additionally, a strontium isotope analysis was conducted to highlight the mobility of the individual. The genomic results revealed the lack of a Y-chromosome and thus a female biological sex, and the mtDNA analyses support a single-individual origin of sampled elements. The genetic affinity is close to present-day North Europeans, and within Sweden to the southern and south-central region. Nevertheless, the Sr values are not conclusive as to whether she was of local or nonlocal origin. The identification of a female Viking warrior provides a unique insight into the Viking society, social constructions, and exceptions to the norm in the Viking time-period. The results call for caution against generalizations regarding social orders in past societies. © 2017 The Authors American Journal of Physical Anthropology Published by Wiley Periodicals, Inc.

    Knee and hip OA is the clinical and pathological outcome of a functional and structural failure of the joint, resulting in pain and physical dysfunction. Despite the similarity in clinical presentation the pathogenesis seems to differ. Where knee OA is associated with obesity and trauma, hip OA is associated with FAI covering three fundamentally different hip deformities, including acetabular dysplasia; all hypothesized to initiates OA development. Where PAO is used worldwide as a joint-preserving procedure in acetabular dysplasia, TKA and THA are the treatment of choice of end stage OA. Traditional main outcomes are clinically objective surgeon-reported endpoints. Patient perceived outcomes are known to differ from these and PROMs are now recommended as the core set of outcomes. When evaluating the outcome in younger patients, this high demanding group can show ceiling-effects of the scores. The overall aim of this thesis was to investigate the consequences of PAO, TKA, and THA in younger patients evaluated by alternative outcomes in relation to satisfaction, fulfillment of expectations, symptoms of depression, the socioeconomic effects, and abilities in sex-life; to improve patient information prior to PAO, TKA and THA surgery. This PhD thesis is based on three studies. Study I is a cross-sectional survey of preserved hip joints with a mean follow-up of ten years after PAO. One hundred patients (121 PAO's) were eligible for inclusion. An inquiry to the National Patient registry identified 36 of PAO's (in 35 patients) being converted to THA. The 61 remaining patients (80 preserved hip joints) were asked to participate in this questionnaire based follow-up. Fifty-five patients (70 preserved hip-joints) accepted and constituted the study population. All patients received a questionnaire concerning aspects of functional ability, patient satisfaction, expectations, and quality of life following PAO. Both Study II and Study III are prospective multicenter cohort

    Background: The use of intensity-modulated radiotherapy (IMRT) in breast cancer reduces clinician-assessed breast tissue toxicity including fibrosis, telangectasia and sub-optimal cosmesis. Patient reported outcome measures (PROMs) are also important as they provide the patient’s perspective. This longitudinal study reports on (a) the effect of forward planned field-in-field IMRT (∼simple IMRT) on PROMs compared to standard RT at 5 years after RT, (b) factors affecting PROMs at 5 years after RT and (c) the trend of PROMs over 5 years of follow up. Methods: PROMs were assessed at baseline (pre-RT), 6, 24 and 60 months after completion of RT using global health (EORTC QLQ C30) and 4 breast symptom questions (BR23). Also, 4 breast RT-specific questions were included at 6, 24 and 60 months: change in skin appearance, firmness to touch, reduction in breast size and overall change in breast appearance since RT. The benefits of simple IMRT over standard RT at 5 years after RT were assessed using standard t-test for global health and logistic regression analysis for breast symptom questions and breast RT-specific questions. Clinical factors affecting PROMs at 5 years were investigated using a multivariate analysis. A repeated mixed model was applied to explore the trend over time for each of PROMs. Results: (89%) 727/815, 84%, 81% and 61% patients completed questionnaires at baseline, 6, 24 and 60 months respectively. Patients reported worse toxicity for all four BR23 breast symptoms at 6 months, which then improved over time (p < 0.0001). They also reported improvement in skin appearance and breast hardness over time (p < 0.0001), with no significant change for breast shrinkage (p = 0.47) and overall breast appearance (p = 0.13). At 5 years, PROMs assessments did not demonstrate a benefit for simple IMRT over standard radiotherapy. Large breast volume, young age, baseline surgical cosmesis and post-operative infection were the most important variables to affect PROMs

    Depressive disorders are one of the leading components of the global burden of disease with a prevalence of up to 14% in the general population. Numerous studies have demonstrated that pharmacotherapy combined with non-pharmacological measures offer the best treatment approach. Psycho-education as an intervention has been studied mostly in disorders such as schizophrenia and dementia, less so in depressive disorders. The present study aimed to assess the impact of psycho-education of patients and their caregivers on the outcome of depression. A total of 80 eligible depressed subjects were recruited and randomised into 2 groups. The study group involved an eligible family member and all were offered individual structured psycho-educational modules. Another group (controls) received routine counselling. The subjects in both groups also received routine pharmacotherapy and counselling from the treating clinician and were assessed at baseline, 2, 4, 8, and 12 weeks using the Hamilton Depression Rating Scale (HDRS), Global Assessment of Functioning (GAF), and Psychological General Well-Being Index (PGWBI). Results from both groups were compared using statistical methods including Chi-square test, Fisher's exact test, Student's t test, Pearson's correlation coefficient, as well as univariate and multiple regression analyses. Baseline socio-demographic and assessment measures were similar in both groups. The study group had consistent improvement in terms of outcome measures with HDRS, GAF, and PGWBI scores showing respective mean change of -15.08, 22, and 60 over 12 weeks. The comparable respective changes in the controls were -8.77, 18.1, and 43.25. Structured psycho-education combined with pharmacotherapy is an effective intervention for people with depressive disorders. Psycho-education optimises the pharmacological treatment of depression in terms of faster recovery, reduction in severity of depression, and improvement in subjective wellbeing and social functioning.

    When an outcome variable is missing not at random (MNAR: probability of missingness depends on outcome values), estimates of the effect of an exposure on this outcome are often biased. We investigated the extent of this bias and examined whether the bias can be reduced through incorporating proxy outcomes obtained through linkage to administrative data as auxiliary variables in multiple imputation (MI). Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) we estimated the association between breastfeeding and IQ (continuous outcome), incorporating linked attainment data (proxies for IQ) as auxiliary variables in MI models. Simulation studies explored the impact of varying the proportion of missing data (from 20 to 80%), the correlation between the outcome and its proxy (0.1-0.9), the strength of the missing data mechanism, and having a proxy variable that was incomplete. Incorporating a linked proxy for the missing outcome as an auxiliary variable reduced bias and increased efficiency in all scenarios, even when 80% of the outcome was missing. Using an incomplete proxy was similarly beneficial. High correlations (> 0.5) between the outcome and its proxy substantially reduced the missing information. Consistent with this, ALSPAC analysis showed inclusion of a proxy reduced bias and improved efficiency. Gains with additional proxies were modest. In longitudinal studies with loss to follow-up, incorporating proxies for this study outcome obtained via linkage to external sources of data as auxiliary variables in MI models can give practically important bias reduction and efficiency gains when the study outcome is MNAR.

    Objective: To evaluate the clinical outcome and cosmetic results in early stage breast cancer patients treated with conservative surgery plus radiation therapy. Methods: From May 1995 to December 2002, 109 such patients were so treated. The post-operative radiotherapy consisted of whole-breast 6 MV linear accelerator irradiation with two tangential half-fields to a total dose of 45-52 Gy (mean 48.6 Gy), followed by a boost irradiation to the tumor bed. Among them, 79 patients received 10-12 Gy (DB) boost by interstitial implantation brachytherapy ( 192 Ir HDR, Nucletron), with single plane implantation for T1 and double plane implantation for T2 tumor. Thirty patients received 15 Gy boost by electron beam. Adjuvant/concurrent chemotherapy (CMF or CEF) and hormonotherapy were also used according to the patients' clinical characteristics. The cosmetic results were scored by both the doctor and the patients. Results: The overall actuarial 5-year survival was 93.8%, with local recurrence of 6.5%. No radiation-induced ulcer was observed in the breast except for acute inflammation at skin pinholes in 5 patients treated by interstitial implant brachytherapy. Among the 75 patients who had had breast examination, cosmetic result scored as good by patient and doctor were 81% and 87%, respectively. The good rate assessed by doctor in brachytherapy boost group and electron beam boost group were 81.2% (39/48) and 85.2% (23/27), There was no significant difference between these two boost techniques (P>0.05). Conclusions: Tumor bed boost irradiation by either brachytherapy or electron beam technique can provide satisfactory local control in early breast cancer treated with conservative surgery plus radiotherapy without increasing the side effects. There is no significant difference in cosmetic result between these two boost techniques. (authors)

    Project PRIDE (Promoting Resilience In Discriminatory Environments) is an 8-session small group intervention aimed at reducing negative mental and behavioral health outcomes resulting from minority stress. This study reports the results of a one-armed pilot test of Project PRIDE, which aimed to examine the feasibility and potential for efficacy of the intervention in a sample of 33 gay and bisexual men aged 18 to 25. The intervention appeared feasible to administer in two different sites and all participants who completed posttreatment (n = 22) or follow-up (n = 19) assessments reported high satisfaction with the intervention. Small to large effect sizes were observed for increases in self-esteem; small effect sizes were found for decreases in loneliness and decreases in minority stress variables; and small and medium effect sizes were found for reductions in alcohol use and number of sex partners, respectively. Overall, Project PRIDE appears to be a feasible intervention with promise of efficacy. Copyright © 2017. Published by Elsevier Ltd.

    The reconstruction of large facial bony defects using microvascular transplants requires extensive surgery to achieve full rehabilitation of form and function. The purpose of this study is to measure the agreement between virtual plans and the actual results of maxillofacial reconstruction. This retrospective cohort study included 30 subjects receiving maxillofacial reconstruction with a preoperative virtual planning. Parameters including defect size, position, angle and volume of the transplanted segments were compared between the virtual plan and the real outcome using paired t test. A total of 63 bone segments were transplanted. The mean differences between the virtual planning and the postoperative situation were for the defect sizes 1.17 mm (95 % confidence interval (CI) (-.21 to 2.56 mm); p = 0.094), for the resection planes 1.69 mm (95 % CI (1.26-2.11); p = 0.033) and 10.16° (95 % CI (8.36°-11.96°); p satisfactory postoperative results are the basis for an optimal functional and aesthetic reconstruction in a single surgical procedure. The technique should be further investigated in larger study populations and should be further improved.

    BACKGROUND: The 'drip-and-ship' paradigm denotes a treatment regimen in patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 h to a comprehensive stroke center. Although the drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population-based level. METHODS: Statewide estimates of thrombolysis, associated in-hospital outcomes, and hospitalization charges were obtained from 2008-2009 Minnesota Hospital Association data for all patients hospitalized with a primary diagnosis of ischemic stroke. Patients who were assigned the drip-and-ship code [International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) V45.88] were classified under the drip-and-ship paradigm. Patients who underwent thrombolysis (ICD-9-CM code 99.10) without drip-and-ship code were classified as primary ED arrival. Patient outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. RESULTS: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n = 473) or the drip-and-ship paradigm (n = 129). IV rt-PA was administered in 30 hospitals, of which 13 hospitals used the drip-and-ship paradigm; the number of patients treated with the drip-and-ship paradigm varied from 1 to 40 between the 13 hospitals. The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with the drip-and-ship paradigm (8.5 vs. 3.1%, respectively; p = 0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or the drip-and-ship paradigm (5.9 vs. 7.0%, respectively). The mean hospital charges were USD

  14. Context Matters: Distinct Disease Outcomes as a Result of Crebbp Hemizygosity in Different Mouse Bone Marrow Compartments.

    Ting Zhou

    Full Text Available Perturbations in CREB binding protein (CREBBP are associated with hematopoietic malignancies, including myelodysplastic syndrome (MDS. Mice hemizygous for Crebbp develop myelodysplasia with proliferative features, reminiscent of human MDS/myeloproliferative neoplasm-unclassifiable (MDS/MPN-U, and a proportion goes on to develop acute myeloid leukemia (AML. We have also shown that the Crebbp+/- non-hematopoietic bone marrow microenvironment induces excessive myeloproliferation of wild-type cells. We now report that transplantation of unfractionated Crebbp+/- bone marrow into wild-type recipients resulted in either early-onset AML or late-onset MDS and MDS/MPN-U. In contrast, purified Lin-Sca-1+c-Kit++ cells primarily gave rise to MDS with occasional transformation to AML. Furthermore, Crebbp+/- common myeloid progenitors and granulocyte/macrophage progenitors could trigger skewed myelopoiesis, myelodysplasia and late-onset AML. Surprisingly, the phenotypically abnormal cells were all of wild-type origin. MDS, MPN and AML can thus all be transferred from Crebbp+/- BM to wild-type hosts but fractionated bone marrow does not recapitulate the full disease spectrum of whole bone marrow, indicating that not only mutational status but also cellular context contribute to disease outcome. This has important consequences for structuring and interpreting future investigations into the underlying mechanisms of myeloid malignancies as well as for their treatment.

    We examined the role of baseline patient characteristics as predictors of outcome (end-state functioning, response and remission) and attrition for cognitive therapy (CT) in social anxiety disorder (SAD). Beyond socio-demographic and clinical variables such as symptom severity and comorbidity status, previously neglected patient characteristics (e.g., personality, self-esteem, shame, interpersonal problems and attachment style) were analysed. Data came from the CT arm of a multicentre RCT with n = 244 patients having DSM-IV SAD. CT was conducted according to the manual by Clark and Wells. Severity of SAD was assessed at baseline and end of treatment with the Liebowitz Social Anxiety Scale (LSAS). Multiple linear regression analyses and logistic regression analyses were applied. Up to 37% of the post-treatment variance (LSAS) could be explained by all pre-treatment variables combined. Symptom severity (baseline LSAS) was consistently negatively associated with end-state functioning and remission, but not with response. Number of comorbid diagnoses was negatively associated with end-state functioning and response, but not with remission. Self-esteem was positively associated with higher end-state functioning and more shame with better response. Attrition could not be significantly predicted. The results indicate that the initial probability for treatment success mainly depends on severity of disorder and comorbid conditions while other psychological variables are of minor importance, at least on a nomothetic level. This stands in contrast with efforts to arrive at an empirical-based foundation for differential indication and argues to search for more potent moderators of therapeutic change rather on the process level. Personality, self-esteem, shame, attachment style and interpersonal problems do not or only marginally moderate the effects of interventions in CT of social phobia. Symptom severity and comorbid diagnoses might affect treatment outcome negatively

    For policy decisions the best geophysical models are needed. To evaluate geophysical models, it is essential that the best available methods for confirmation are used. A hotly debated issue on confirmation in climate science (as well as in philosophy) is the requirement of use-novelty (i.e. that data can only confirm models if they have not already been used before. This talk investigates the issue of use-novelty and double-counting for geophysical models. We will see that the conclusions depend on the framework of confirmation and that it is not clear that use-novelty is a valid requirement and that double-counting is illegitimate.

    Purpose To determine the demographic, clinical, decision-making, and quality-of-life factors that are associated with treatment decision regret among long-term survivors of localized prostate cancer. Patients and Methods We evaluated men who were age ≤ 75 years when diagnosed with localized prostate cancer between October 1994 and October 1995 in one of six SEER tumor registries and who completed a 15-year follow-up survey. The survey obtained demographic, socioeconomic, and clinical data and measured treatment decision regret, informed decision making, general- and disease-specific quality of life, health worry, prostate-specific antigen (PSA) concern, and outlook on life. We used multivariable logistic regression analyses to identify factors associated with regret. Results We surveyed 934 participants, 69.3% of known survivors. Among the cohort, 59.1% had low-risk tumor characteristics (PSA decision regret: 8.2% of those whose disease was managed conservatively, 15.0% of those who received surgery, and 16.6% of those who underwent radiotherapy. Factors associated with regret on multivariable analysis included reporting moderate or big sexual function bother (reported by 39.0%; OR, 2.77; 95% CI, 1.51 to 5.0), moderate or big bowel function bother (reported by 7.7%; OR, 2.32; 95% CI, 1.04 to 5.15), and PSA concern (mean score 52.8; OR, 1.01 per point change; 95% CI, 1.00 to 1.02). Increasing age at diagnosis and report of having made an informed treatment decision were inversely associated with regret. Conclusion Regret was a relatively infrequently reported outcome among long-term survivors of localized prostate cancer; however, our results suggest that better informing men about treatment options, in particular, conservative treatment, might help mitigate long-term regret. These findings are timely for men with low-risk cancers who are being encouraged to consider active surveillance.

    Purpose: The benefit of adjuvant radiotherapy (RT) after surgical resection for extrahepatic cholangiocarcinoma has not been clearly established. We analyzed survival outcomes of patients with resected extrahepatic cholangiocarcinoma and examined the effect of adjuvant RT. Methods and Materials: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program between 1973 and 2003. The primary endpoint was the overall survival time. Cox regression analysis was used to perform univariate and multivariate analyses of the following clinical variables: age, year of diagnosis, histologic grade, localized (Stage T1-T2) vs. regional (Stage T3 or greater and/or node positive) stage, gender, race, and the use of adjuvant RT after surgical resection. Results: The records for 2,332 patients were obtained. Patients with previous malignancy, distant disease, incomplete or conflicting records, atypical histologic features, and those treated with preoperative/intraoperative RT were excluded. Of the remaining 1,491 patients eligible for analysis, 473 (32%) had undergone adjuvant RT. After a median follow-up of 27 months (among surviving patients), the median overall survival time for the entire cohort was 20 months. Patients with localized and regional disease had a median survival time of 33 and 18 months, respectively (p < .001). The addition of adjuvant RT was not associated with an improvement in overall or cause-specific survival for patients with local or regional disease. Conclusion: Patients with localized disease had significantly better overall survival than those with regional disease. Adjuvant RT was not associated with an improvement in long-term overall survival in patients with resected extrahepatic bile duct cancer. Key data, including margin status and the use of combined chemotherapy, was not available through the SEER database.

  20. Managing a duopolistic water market with confirmed proposals. An experiment

    Full Text Available We report results from experimental water markets in which owners of two different sources of water supply water to households and farmers. The final water quality consumed by each type of consumer is determined through mixing of qualities from two different resources. We compare the standard duopolistic market structure with an alternative market clearing mechanism inspired by games with confirmed strategies (which have been shown to yield collusive outcomes. As in the static case, complex dynamic markets operating under a confirmed proposals protocol yield less efficient outcomes because coordination among independent suppliers has the usual effects of restricting output and increasing prices to the users. Our results suggest that, when market mechanisms are used to allocate water to its users, the rule of thumb used by competition authorities can also serve as a guide towards water market regulation.

    Se presentan resultados de un experimento con mercados acuíferos en el que los propietarios de agua de distinta calidad la ofrecen a hogares y agricultores. La calidad finalmente consumida por cada tipo de consumidor se determina a partir de una mezcla de las dos calidades. Se compara el duopolio estándar con una forma alternativa de cerrar el mercado que está inspirada en los juegos con propuestas confirmadas, que consiguen resultados relativamente más colusivos. Como en el caso estático, los mercados dinámicos y complejos que operan bajo un protocolo de propuestas confirmadas son menos eficientes porque la coordinación entre oferentes independientes tiene los efectos de restringir el output y de provocar un crecimiento de los precios. Nuestros resultados sugieren que cuando los mecanismos de mercado se utilizan para distribuir el agua a sus usuarios, la regla utilizada por parte de las autoridades de la competencia puede servir también como guía para la regulación de los mercados acuíferos.

    Although admissions of children with anorexia nervosa (AN) are increasing, there remains a dearth of up-to-date knowledge of the course and outcome of early-onset AN. The aim of the present study was to investigate the outcomes of patients with AN onset before the age of 14. Sixty-eight consecutive former patients who met the DSM-IV criteria for AN and who had been treated at one of three German university hospitals were asked to participate in a follow-up study. Body mass index, body height, outcome of the eating disorder (ED), psychiatric morbidity, and health related quality of life (HRQoL) were assessed through a personal examination after an average time span of 7.5 years (range: 4.5-11.5 years) after admission. One patient had died. Fifty-two subjects with a mean age of 12.5 (SD 1.0) years at admission and of 20.2 (SD 2.0) years at follow-up agreed to participate in the follow-up assessment, aggregating to 77.9% of the original sample. Approximately 41% of the participants had a good outcome, while 35% and 24% had intermediate and poor outcomes, respectively. Twenty-eight percent of the sample met the DSM-IV criteria for a current non-ED psychiatric disorder, and 64% met the criteria for a past non-ED psychiatric disorder. Mental HRQoL and ED-specific psychopathology was strongly associated with the outcome of AN. Average body height was below the normal range. A higher weight at admission was the only significant positive indicator of outcome. Childhood AN is a serious disorder with an unfavorable course in many patients and high rates of chronicity and psychiatric comorbidity in young adulthood. Early detection and intervention are urgently needed. © 2018 Wiley Periodicals, Inc.

    Changes in weight status from adolescence to adulthood may be associated with varying social, vocational, economic, and educational outcomes, which may differ by sex. We studied whether there are differences in adult outcomes by sex for different weight status changes in the transition to adulthood. Using data from the National Longitudinal Study of Adolescent Health, participants were categorized by weight status from adolescence into adulthood. We examined self-reported outcomes in adulthood for living with parents, being married, being a parent, employment, receipt of public assistance, income, and college graduation by weight groupings (healthy-healthy, healthy-overweight/obese, overweight/obese-overweight/obese, overweight/obese-healthy). The effect of changes in weight status on the adult outcomes was modeled, controlling for sex, age, parental education, and race/ethnicity. There were differences by sex for many of the self-reported outcomes, especially educational and economic outcomes. Female subjects who became overweight/obese between adolescence and adulthood or remained so had worse economic and educational findings as adults compared to male subjects. Overall, for female subjects, becoming and remaining overweight/obese was associated with worse outcomes, while for male subjects, adolescent obesity was more important than isolated adult obesity. The relationship between obesity and life situations may be more negative for female subjects in the transition to adulthood. The findings emphasize that adolescent obesity, and not just obesity isolated in adulthood, is important for characteristics achieved in adulthood. Copyright © 2014 Academic Pediatric Association.

    Outcome measures can be used in prosthetic practices to evaluate interventions, inform decision making, monitor progress, document outcomes, and justify services. Strategies to enhance prosthetists' ability to use outcome measures are needed to facilitate their adoption in routine practice. To assess prosthetists' use of outcome measures and evaluate the effects of training on their confidence in administering performance-based measures. Cross-sectional and single-group pretest-posttest survey. Seventy-nine certified prosthetists (mean of 16.0 years of clinical experience) were surveyed about their experiences with 20 standardized outcome measures. Prosthetists were formally trained by the investigators to administer the Timed Up and Go and Amputee Mobility Predictor. Prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor was measured before and after training. The majority of prosthetists (62%) were classified as non-routine outcome measure users. Confidence administering the Timed Up and Go and Amputee Mobility Predictor prior to training was low-to-moderate across the study sample. Training significantly (p measures. Interactive training resulted in a statistically significant increase of prosthetists' confidence in administering the Timed Up and Go and Amputee Mobility Predictor and may facilitate use of outcome measures in clinical practice. Frequency of outcome measure use in the care of persons with limb loss has not been studied. Study results suggest that prosthetists may not regularly use standardized outcome measures and report limited confidence in administering them. Training enhances confidence and may encourage use of outcome measures in clinical practice. © The International Society for Prosthetics and Orthotics 2014.

    To evaluate the long-term effectiveness and safety of the adjustable transobturator male system (ATOMS ® , Agency for Medical Innovations A.M.I., Feldkirch, Austria) in a European-wide multicentre setting. In all, 287 men with stress urinary incontinence (SUI) were treated with the ATOMS device between June 2009 and March 2016. Continence parameters (daily pad test/pad use), urodynamics (maximum urinary flow rate, voiding volume, residual urine), and pain/quality of life (QoL) ratings (visual analogue scale/Leeds Assessment of Neuropathic Symptoms and Signs, International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]/Patient Global Impression of Improvement [PGI-I]) were compared preoperatively and after intermediate (12 months) as well as after individual maximum follow-up. Overall success rate, dry rate (ATOMS devices are still functioning; 56 (20%) were removed, the most common reason being local titanium intolerance (41%) and leak/dysfunction (30%). The operating time and continence outcome varied between port generations. In this regard the latest port generation (silicone-covered scrotal port) was superior to its predecessors. Primary implantation (P = 0.002), good physical health (P = 0.001), and no history of radiotherapy (P ATOMS device is safe and shows high treatment efficacy and patient satisfaction in the largest cohort study to date. The latest generation, with its pre-attached silicone-covered scrotal port, is superior to its predecessors. Significantly better results were achieved with primary implantation and in those without a history of radiotherapy. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

    To assess implant survival rates and peri-implant bone loss of 2 titanium-zirconium implants supporting maxillary overdentures at 1 year of loading. Twenty maxillary edentulous patients (5 women and 15 men) being dissatisfied with their complete dentures were included. In total, 40 diameter-reduced titanium-zirconium implants were placed in the anterior maxilla. Local guided bone regeneration (GBR) was allowed if the treatment did not compromise implant stability. Following 3 to 5 months of healing, implant-supported overdentures were inserted on two ball anchors. Implants and overdentures were assessed at 1, 2, 4, and 8 weeks after implant insertion and 2, 4, and 12 months after insertion of overdentures (baseline). Standardized radiographs were taken at implant loading and 1 year. Implant survival rates and bone loss were the primary outcomes. Nineteen patients (1 dropout) with 38 implants were evaluated at a mean follow-up of 1.1 years (range 1.0-1.7 years). One implant failed resulting in an implant survival rate of 97.3%. There was a significant peri-implant bone loss of the implants at 1 year of function (mean, 0.7 mm, SD = 1.1 mm; median: 0.48 mm, IQR = 0.56 mm). There was a high 1-year implant survival rate for edentulous patients receiving 2 maxillary implants and ball anchors as overdenture support. However, several implants exhibited an increased amount of bone loss of more than 2 mm. Overdentures supported by 2 maxillary implants should thus be used with caution as minimally invasive treatment for specific patients encountering problems with their upper dentures until more long-term data is available. © 2016 John Wiley & Sons A/S.

    Background -Late survival and symptomatic status of children with hypertrophic cardiomyopathy (HCM) have not been well defined. We examined long-term outcomes for pediatric HCM. Methods -The National Australian Childhood Cardiomyopathy Study is a longitudinal population-based cohort study of children (0-10 years) diagnosed with cardiomyopathy between 1987 and 1996. The primary study end-point was time to death or cardiac transplantation. Results -There were 80 patients with HCM with median age at diagnosis of 0.48 (Inter-quartile range [IQR] 0.1, 2.5) years. Freedom from death/transplantation (95% confidence interval [CI]) was 86 (77-92)% one year after presentation, 80 (69-87)% at 10 years and 78 (67-86)% at 20 years. From multivariable analyses, risk factors for death/transplantation included symmetric left ventricular hypertrophy at the time of diagnosis (hazard ratio [HR] 4.20 95%CI 1.60, 11.05 p=0.004), Noonan syndrome (HR 2.88, 95%CI 1.02, 8.08, p=0.045), higher posterior wall thickness z-score (HR 1.45, 95%CI 1.22, 1.73, p<0.001) and lower fractional shortening z-score (HR 0.84, 95%CI 0.74, 0.95, p=0.005) during follow-up. Nineteen (23%) subjects underwent left ventricular myectomy. At median 15.7 years' follow-up, 27 (42%) of 63 survivors were treated with beta-blocker and 13 (21%) had an implantable cardioverter-defibrillator. Conclusions -The highest risk of death or transplantation for children with HCM is within one year post-diagnosis, with low attrition rates thereafter. Many subjects receive medical, surgical or device therapy.

    Background Controversy exists about how to effectively measure patient reported outcomes in IBS clinical trials. Pain numeric rating scales (NRS) are widely used in the non-IBS pain literature. The FDA has proposed using the NRS in IBS. Aim To test the psychometrics of an abdominal pain NRS in IBS. Methods We analyzed data from a longitudinal cohort of Rome III IBS subjects. At entry, subjects completed a 10-point NRS, bowel symptoms, IBS severity measurements (IBSSS, FBDSI), health related quality of life indices (IBS-QOL, EQ5D), and the worker productivity activity index (WPAI). We repeated assessments at 3 months along with a response scale to calculate the minimal clinically important difference (MCID). Results There were 277 subjects (82% women; age=42±15) at baseline and 90 at 3 months. The NRS correlated cross-sectionally with IBSSS (r=0.60; p<0.0011), FBDSI (r=0.49; p<0.0001), IBS-QOL (r=0.43; p<0.0001), EQ5D (r=0.48; p<0.0001), presenteeism (r=0.39; p<0.0001), absenteeism (r=0.17; p=0.04), and distension (r=0.46; p<0.0001), but not stool frequency or form. The MCID was 2.2 points, correlating with a 29.5% reduction over time. Conclusions An abdominal pain NRS exhibits excellent validity and can be readily interpreted with an MCID in patients with IBS. These data support the use of the NRS in IBS clinical trials. PMID:19751360

    The Yucca Mountain Performance Confirmation program consists of tests, monitoring activities, experiments, and analyses to evaluate the adequacy of assumptions, data, and analyses that form the basis of the conceptual and numerical models of flow and transport associated with a proposed radioactive waste repository at Yucca Mountain, Nevada. The Performance Confirmation program uses an eight-stage risk-informed, performance-based approach. Selection of the Performance Confirmation activities (a parameter and a test method) for inclusion in the Performance Confirmation program was done using a risk-informed performance-based decision analysis. The result of this analysis and review was a Performance Confirmation base portfolio that consists of 20 activities. The 20 Performance Confirmation activities include geologic, hydrologic, and construction/engineering testing. Several of the activities were initiated during site characterization and are ongoing. Others activities will commence during construction and/or post emplacement and will continue until repository closure

    To assess the clinical utility of supplementary PCRs following a positive cobas 4800 CT/NG PCR screening test result. Laboratory reports, for Chlamydia trachomatis or Neisseria gonorrhoeae, issued to genitourinary medicine patients between April 2010 and April 2011 were reviewed retrospectively. Positive reports were routinely confirmed by supplementary PCRs and N gonorrhoeae culture. Clinical records of patients with unconfirmed positive (equivocal) reports were retrieved to determine if the infection was confirmed by a second sample obtained at patient recall and the impact of this process on antibiotic management. Over 15 000 patients were tested during the study period. The prevalence of chlamydia and gonorrhoea was 972 (5.75%) and 76 (0.50%), respectively. A further 78 chlamydia and 2 gonorrhoea equivocal reports were issued. Only 56 (72%) patients with an equivocal chlamydia report returned to the clinic, and of these, only 41 (73%) gave a second sample to retest. Positive predictive value (PPV) of the PCR screening test was calculated at 98.0% and 97.5% for detection of chlamydia infection from urine and rectal swabs, respectively. Most patients accepted antibiotic treatment before their infection status had been confirmed. Prevalence of gonorrhoea infection was low but the PPV of the screening PCR in urine specimens remained high (98.75%). Equivocal reports introduce delays to patient management, while the risk of unnecessary antibiotic therapy appears acceptable to most patients. The cobas 4800 CT/NG PCR screening assay can achieve UK testing standards (PPV >90%) for chlamydia, and low prevalence gonorrhoea in urine without supplementary tests. A patient-led confirmation algorithm is proposed.

    Background and Objectives: Over the past few years, ultrasonography is increasingly being used to confirm the correct placement of endotracheal tube (ETT). In our study, we aimed to compare it with the traditional clinical methods and the gold standard quantitative waveform capnography. Two primary outcomes were measured in our study. First was the sensitivity and specificity of ultrasonography against the other two methods to confirm endotracheal intubation. The second primary outcome assessed was the time taken for each method to confirm tube placement in an emergency setting. Methods: This is a single-centered, prospective cohort study conducted in an emergency department of a tertiary care hospital. We included 100 patients with indication of emergency intubation by convenient sampling. The intubation was performed as per standard hospital protocol. As part of the study protocol, ultrasonography was used to identify ETT placement simultaneously with the intubation procedure along with quantitative waveform capnography (end-tidal carbon dioxide) and clinical methods. Confirmation of tube placement and time taken for the same were noted by three separate health-care staffs. Results and Discussion: Out of the 100 intubation attempts, five (5%) had esophageal intubations. The sensitivity and specificity of diagnosis using ultrasonography were 97.89% and 100%, respectively. This was statistically comparable with the other two modalities. The time taken to confirm tube placement with ultrasonography was 8.27 ± 1.54 s compared to waveform capnography and clinical methods which were 18.06 ± 2.58 and 20.72 ± 3.21 s, respectively. The time taken by ultrasonography was significantly less. Conclusions: Ultrasonography confirmed tube placement with comparable sensitivity and specificity to quantitative waveform capnography and clinical methods. But then, it yielded results considerably faster than the other two modalities. PMID:28584427

Despite improvements in imaging techniques allowing for earlier diagnosis, OG is rare among the pediatric population. This study examines a large cohort of OG patients in an effort to define the demographic, clinical, and pathologic factors associated with clinical and survival outcomes.Methods: Data on 7,001 OG patients were abstracted from the Surveillance, Epidemiology, and End Result (SEER database (1973–2013. Pediatric patients were defined as ≤19 years old, and adult patients were defined as age ≥20 years.Results: Among 7,001 OG patients, 6.5% were pediatric (mean age 12 ± 6 years, and 93.5% were adult (mean age 46 ± 15 years. Overall, OGs were more common among males, with a male-to-female ratio of 1.28:1. Overall, OGs were more common among Caucasians (76.9% and also among the African American (10.8% pediatric vs. 4.0% adult and Hispanic (12.8% pediatric vs. 11.8% adult. OGs occurred most commonly in the temporal lobe of pediatric patients and the frontal lobes of adults. Surgical resection was the primary treatment modality for both pediatric and adult populations (70.6% and 40.5%, followed by combined surgery and radiation (19.7% and 41.2%. Surgical resection was associated with significantly improved survival in both groups. Pediatric patients had a lower overall mortality (19.8% vs. 48.5% and lower cancer-specific mortality (17.6% vs. 36.8%.Conclusion: OGs most often present in Caucasian males in their fifth decade of life with tumors >4 cm in size

    The authors report on 21 cases of confirmed multiple sclerosis examined by both CT and magnetic resonance tomography. To safeguard the results, strict criteria were applied in accordance with the suggestions made by neurological work teams. Pathological lesons were seen in 20 patients; the MR image did not reveal anything abnormal in one case. On the average, 10.3 lesions were seen in the MR tomogram, whereas CT images showed on the average only 2.1 foci. The size and number of lesions in the MR tomogram were independent of the duration of the disease, the presented clinical symptoms, or the type of treatment at the time of examination. Evidently the sensitivity of MR tomography is very high in MS patients, but it has not yet been clarified to what extent this applies also to the specificity. Further research is mandatory. First experiences made by us show that lesions of a similar kind can also occur in diseases such as malignant lymphoma involving the brain, in vitamin B 12 deficiency syndrome, or encephalitis, and can become manifest in the MR tomogram.

    2017-02-01

    This study explored how coping with war-related traumatic events in Sierra Leone impacted mental health outcomes among 529 youth (aged 10-17 at baseline; 25% female) using longitudinal data from three time points (Time 1 in 2002, Time 2 in 2004, and Time 3 in 2008). We examined two types of coping items (approach and avoidance); used multiple regression models to test their relations with long-term mental health outcomes (internalizing behaviors, externalizing behaviors, adaptive/prosocial behaviors, and posttraumatic stress symptoms); and used mediation analyses to test whether coping explained the relation between previous war exposures (being raped, death of parent(s), or killing/injuring someone during the war) and those outcomes. We found that avoidance coping items were associated with lower internalizing and posttraumatic stress behaviors at Time 3, and provided some evidence of mediating the relation between death of parent(s) during the war and the two outcomes mentioned above. Approach coping was associated with higher Time 3 adaptive/prosocial behaviors, whereas avoidance coping was associated with lower Time 3 adaptive/prosocial behaviors. Avoidance coping may be a protective factor against mental illness, whereas approach coping may be a promotive factor for adaptive/prosocial behaviors in war-affected societies. This study has important implications for designing and implementing mental health interventions for youth in postconflict settings.

    1998-07-01

    The purpose of this report is to present separately for black and white patients with advanced glaucoma 7-year results of two alternative surgical intervention sequences. A randomized controlled trial. A total of 332 black patients (451 eyes), 249 white patients (325 eyes), and 10 patients of other races (13 eyes) participated. Potential follow-up ranged from 4 to 7 years. Eyes were randomly assigned to either an argon laser trabeculoplasty (ALT)-trabeculectomy-trabeculectomy (ATT) sequence or a trabeculectomy-ALT-trabeculectomy (TAT) sequence. The second and third interventions were offered after failure of the first and second interventions, respectively. Average percent of eyes with decrease of visual field (APDVF), average percent of eyes with decrease of visual acuity (APDVA), and average percent of eyes with decrease of vision (APDV) are the outcome measures. Decrease of visual field (DVF) is an increase from baseline of at least 4 points on a glaucoma visual field defect scale ranging from 0 to 20, decrease of visual acuity (DVA) is a decrease from baseline of at least 15 letters (3 lines), and decrease of vision (DV) is the occurrence of either DVF or DVA. The averages are of percent decreases observed at 6-month intervals from the first 6-month visit to the end of the specified observation period. In both black and white patients throughout 7-year follow-up, the mean decrease in intraocular pressure was greater in eyes assigned to TAT, and the cumulative probability of failure of the first intervention was greater in eyes assigned to ATT. In black patients, APDVF, APDVA, and APDV are less for the ATT sequence than for the TAT sequence throughout the 7 years. In white patients, APDVF also favors the ATT sequence but only for the first year, after which it favors the TAT sequence through the seventh year; APDVA also favors the ATT sequence, but the ATT-TAT difference progressively diminishes over 7 years; and APDV favors ATT over TAT initially, but after 4

    Abstract To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis. We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition. Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002–1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063–0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338–1.934, P = .663). Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome

    Previous cross-sectional and longitudinal studies reported a negative correlation between fatherhood and testosterone (T) levels, likely due to a centrally mediated downregulation of the hypothalamic-pituitary-gonadal axis. Moreover, epidemiological data indicate that fatherhood might affect metabolic and cardiovascular outcomes, although different results have been reported. Up to now, no studies have evaluated these associations in a population of men seeking treatment for sexual dysfunction (SD). To explore biological and clinical correlates of number of children (NoC) and its possible associations with forthcoming major cardiovascular events (MACE) in a sample of men with SD. A consecutive series of 4,045 subjects (mean age 52 ± 13.1 years old) attending the Outpatient Clinic for SD was retrospectively studied. A subset of the previous sample (N = 1,687) was enrolled in a longitudinal study. Information on MACE was obtained through the City of Florence Registry Office. Among patients studied, 31.6% had no children, while 26.3% reported having one child, 33.4% two, and 8.8% three or more children. Although fatherhood was negatively related with follicle-stimulating hormone levels and positively with testis volume, we found a NoC-dependent, stepwise decrease in T plasma levels, not compensated by a concomitant increase in luteinizing hormone. NoC was associated with a worse metabolic and cardiovascular profile, as well as worse penile blood flows and a higher prevalence of metabolic syndrome (MetS). In the longitudinal study, after adjusting for confounders, NoC was independently associated with a higher incidence of MACE. However, when the presence of MetS was introduced as a further covariate, the association was no longer significant. This study supports the hypothesis that bond maintenance contexts and fatherhood are associated with an adaptive downregulation of the gonadotropin-gonadal axis, even in a sample of men with SD. Moreover, our data suggest that

    While some studies have found that those who perceive a behavior to be more risky are less likely to engage in it, others have found that those who engage in more risky behaviors see themselves as being more at-risk. Using an online questionnaire we investigated whether such conflicting findings may be due to the types of risk-questions employed in past studies. We assessed risk-perception using outcome-focused questions (e.g. the likelihood of being in an accident) and a behavior-focused question (the riskiness of speeding). Participants who reported engaging in more risky driving gave higher estimates of their chances of experiencing a negative outcome. However, those same participants gave lower estimates of the general riskiness of risky driving. Drivers may think about the risks of risky driving in different ways depending on the focus of the questions. Published by Elsevier Ltd.

    Surgical resection of extrahepatic biliary malignancies has been increasingly centralized at high-volume tertiary care centers. While this has improved outcomes overall, increased travel burden has been associated with worse survival for many other malignancies. We hypothesized that longer travel distances are associated with worse outcomes for these patients as well. Data was analyzed from the US Extrahepatic Biliary Consortium database, which retrospectively reviewed patients who received resection of extrahepatic biliary malignancies at 10 high-volume centers. Driving distance to the patient's treatment center was measured for 1025 patients. These were divided into four quartiles for analysis: travel distances were associated with decreased overall survival, especially in the 3rd quartile of our study. Patients traveling longer distances also had a lower household income, suggesting that these patients have significant barriers to care.

    Retrospective analyses have demonstrated correlation between patient-reported allergies and negative outcomes after total joint arthroplasty. We sought to validate these observations in a prospective cohort. One hundred forty-four patients undergoing total hip arthroplasty and 302 patients undergoing total knee arthroplasty were prospectively enrolled. Preoperatively, patients listed their allergies and completed the Medical Outcomes Study Short Form 36 (SF-36) and the Charlson Comorbidity Index (CCI) Questionnaire. At a mean of 17 months (range 12-25 months) postoperatively, SF-36, CCI, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were obtained by telephone survey. Regression analysis was used to determine the strength of correlation between patient age, comorbidity burden, and number of allergies and outcome measurements. In 446 patients, 273 reported at least 1 allergy. The number of allergies reported ranged from 0 to 33. Penicillin or its derivative was the most frequently reported allergy followed by sulfa, environmental allergen, and narcotic pain medication. Patients reporting at least 1 allergy had a significantly lower postoperative SF-36 Physical Component Score compared to those reporting no allergies (51.3 vs 49.4, P = .01). The SF-36 postoperative Mental Component Score was no different between groups. Multivariate regression analysis showed that age and patient reported allergies, but not comorbidities, were independently associated with worse postoperative SF-36 Physical Component Summary (PCS) and WOMAC score. Patients with allergies experienced the same improvement in SF-36 PCS as those without an allergy. Comorbidities did not correlate with patient-reported function postoperatively. Patients who report allergies have lower postoperative outcome scores but may experience the same increment in improvement after total joint arthroplasty. Copyright © 2016 Elsevier Inc.

    Debate persists over the association between blood transfusions, especially those considered discretionary, and outcomes after cardiac operations. Using data from the Maryland Cardiac Surgery Quality Initiative, we sought to determine whether outcomes differed among coronary artery bypass grafting (CABG) patients receiving 1 U of red blood cells (RBCs) vs none. We used a statewide database to review patients who underwent isolated CABG from July 1, 2011, to June 30, 2016, across 10 Maryland cardiac surgery centers. We included patients who received 1 U or fewer of RBCs from the time of the operation through discharge. Propensity scoring, using 20 variables to control for treatment effect, was performed among patients who did and did not receive a transfusion. These two groups were matched 1:1 to assess for differences in our primary outcomes: operative death, prolonged postoperative length of stay (>14 days), and a composite postoperative respiratory complication of pneumonia or reintubation, or both. Of 10,877 patients who underwent CABG, 6,124 (56%) received no RBCs (group 1) during their operative hospitalization, and 981 (9.0%) received 1 U of RBCs (group 2), including 345 of 981 patients (35%) who received a transfusion intraoperatively. Propensity score matching generated 937 well-matched pairs. Compared with group 2, propensity-matched analysis revealed significantly greater 30-day survival in group 1 (99% vs 98%, p = 0.02) and reduced incidence of prolonged length of stay (3.7% vs 4.0%, p < 0.01). Our collaborative statewide analysis demonstrated that even 1 unit of blood was associated with significantly worse survival and longer length of stay after CABG. Multiinstitutional quality initiatives may seek to address discretionary transfusions and possess the potential to improve patient outcomes. Copyright © 2018 The Society of Thoracic Surgeons.

    Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment. 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8%) attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators. Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19) compared to those presenting moderate (Δ BMI-SDS -0.14) and high social risk (Δ BMI-SDS -0.11). Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents.

    To explore the association of American Society of Anesthesiologists (ASA) classification with cataract surgery outcomes. Five Veterans Affairs Medical Centers, United States. Retrospective observational cohort study. The study analyzed the outcomes of cataract surgery cases. Corrected distance visual acuity (CDVA), unanticipated events, and vision-related quality of life (VRQL) were assessed using the National Eye Institute Visual Function Questionnaire (NEI-VFQ), comparing ASA classes I through IV. For some analyses, ASA classes I and II were designated as Group A and ASA classes III and IV were designated Group B. Of the 4923 cases, 875 (17.8%) were in Group A, 4032 (81.9%) were in Group B, and 16 (0.3%) had missing data. The mean CDVA and mean composite NEI-VFQ score improved after cataract surgery in both groups (P < .0001); however, Group A had a better mean postoperative CDVA and postoperative VFQ composite scores than Group B (P < .0001, both outcomes). A higher ASA class was associated with an increased risk for 2 unanticipated events; that is, clinically significant macular edema (CSME) (Group A: 4 [0.47%] versus Group B: 50 [1.28%]; adjusted odds ratio [OR], 3.02; 95% confidence interval [CI], 1.02-13.05; P = 0.04) and readmission to the hospital within 30 days (2 [0.23%] versus 56 [1.41%]; OR, 8.26; 95% CI, 1.71-148.62; P = .004) CONCLUSIONS: Among United States veterans, the ASA classification could be an important predictor of VRQL and visual outcomes. In this cohort, it was associated with an increased risk for 2 serious unanticipated events-CSME and readmission to the hospital-both costly, unwanted outcomes.

    To evaluate the perioperative outcomes of zero ischemia radiofrequency ablation-assisted tumor enucleation. Patients undergoing zero ischemia radiofrequency ablation-assisted tumor enucleation were retrospectively identified from July 2008 to March 2013. The tumor was enucleated after RFA treatment. R.E.N.A.L., PADUA and centrality index (C-index) score systems were used to assess each tumor case. We analyzed the correlation of perioperative outcomes with these scores. Postoperative complications were graded with Clavien-Dindo system. Multivariate logistic regression analyses were used to assess risk of complications. Among 182 patients assessed, median tumor size, estimated blood loss, hospital stay and operative time were 3.2 cm (IQR 2.8-3.4), 80 ml (IQR 50-120), 7 days (IQR 6-8) and 100 min (IQR 90-120), respectively. All three scoring systems were strongly correlated with estimated blood loss, hospital stay and operative time. We found 3 (1.6%) intraoperative and 23 (12.6%, 13 [7.1%] Grade 1 and 10 [5.5%] Grade 2 & 3a) postoperative complications. The median follow-up was 55.5 months (IQR 45-70). Additionally, the complexities of R.E.N.A.L., PADUA and C-index scores were significantly correlated with complication grades (P radiofrequency ablation-assisted tumor enucleation is considered an effective nephron-sparing treatment.

    The Dialysis Outcomes and Practice Patterns Study (DOPPS) is a prospective, observational study designed to evaluate practice patterns in random samples of haemodialysis facilities and patients across three continents. Participating countries include France, Germany, Italy, Spain and the UK (Euro-DOPPS), Japan and the USA. DOPPS data collection has used the same questionnaires and protocols across all participating countries to assess components of dialysis therapy and outcomes. This study focuses on dialysis prescription, adherence and nutrition among the Euro-DOPPS countries. In each Euro-DOPPS country, patients were selected randomly from 20-21 representative facilities. Simple means and frequencies were calculated to compare relevant data elements to gain insights into differences in therapeutic aspects among nationally representative patients. Participants entering the study within 90 days of beginning dialysis therapy were excluded from these analyses. Among the five countries, mean delivered dose as measured by normalized urea clearance (Kt/V) varied from 1.28 to 1.50 and was accompanied by differences in dialysis prescription components, including blood flow rates, treatment times, and dialyser membrane and flux characteristics. By country, a nearly 2-fold difference was observed in indicators of patient adherence and management (skipping and shortening dialysis, hyperkalaemia, hyperphosphataemia and high interdialytic weight gain). Indicators of malnutrition varied substantially. This study demonstrates differences in the management of haemodialysis patients across Euro-DOPPS and offers opportunities for improving dialysis dose, adherence and nutrition. Correlation of differences in practice patterns at the dialysis unit level with patient outcomes will offer new insights into improving dialysis therapy.

  18. Distribution and Outcomes of a Phenotype-Based Approach to Guide COPD Management: Results from the CHAIN Cohort.

    Directory of Open Access Journals (Sweden)

    Full Text Available The Spanish guideline for COPD (GesEPOC recommends COPD treatment according to four clinical phenotypes: non-exacerbator phenotype with either chronic bronchitis or emphysema (NE, asthma-COPD overlap syndrome (ACOS, frequent exacerbator phenotype with emphysema (FEE or frequent exacerbator phenotype with chronic bronchitis (FECB. However, little is known on the distribution and outcomes of the four suggested phenotypes.We aimed to determine the distribution of these COPD phenotypes, and their relation with one-year clinical outcomes.We followed a cohort of well-characterized patients with COPD up to one-year. Baseline characteristics, health status (CAT, BODE index, rate of exacerbations and mortality up to one year of follow-up were compared between the four phenotypes.Overall, 831 stable COPD patients were evaluated. They were distributed as NE, 550 (66.2%; ACOS, 125 (15.0%; FEE, 38 (4.6%; and FECB, 99 (11.9%; additionally 19 (2.3% COPD patients with frequent exacerbations did not fulfill the criteria for neither FEE nor FECB. At baseline, there were significant differences in symptoms, FEV1 and BODE index (all p<0.05. The FECB phenotype had the highest CAT score (17.1±8.2, p<0.05 compared to the other phenotypes. Frequent exacerbator groups (FEE and FECB were receiving more pharmacological treatment at baseline, and also experienced more exacerbations the year after (all p<0.05 with no differences in one-year mortality. Most of NE (93% and half of exacerbators were stable after one year.There is an uneven distribution of COPD phenotypes in stable COPD patients, with significant differences in demographics, patient-centered outcomes and health care resources use.

    Maternal infections are associated with intrauterine growth restriction (IUGR) and preterm birth (PTB). Dental infections are common in low-income settings, but their contribution to adverse pregnancy outcomes is unknown. We studied the epidemiology of dental periapical infections among pregnant women and their association to foetal growth restriction and the duration of pregnancy in a rural sub-Saharan African population. This was a cross-sectional study on the association between maternal dental periapical infections and birth outcomes, in Malawi, Africa. We assessed oral health clinically and radiologically among recently delivered women with known duration of pregnancy and measured birthweight (BW), length and head circumference of their infants. Of 1024 analysed participants, 23.5% had periapical infections. Mean duration of pregnancy was 39.4 weeks, BW 2979 g and length 49.7 cm. Women with periapical infection had mean (95% CI) pregnancy duration 0.4 weeks (0.1-0.8) shorter and delivered infants with 79 g (13-145) lower BW and 0.5 cm (0.2-0.9) shorter neonatal length than women without periapical infection. The incidence of PTB was 10.0% among women with periapical infection and 7.3% among those without (adjusted difference 3.5%, 95% CI -1.1-8.1%). Corresponding prevalences for stunting were 20.9% and 14.2% (adjusted difference 9.0%, 95% CI 2.7%-15.2%). The population-attributable risk fraction attributable to periapical infection was 9.7% for PTB and 12.8% for stunting. Periapical infection was associated with shorter pregnancy duration and IUGR in the study area; interventions addressing this risk factor may improve birth outcomes in low-income settings. © 2015 John Wiley & Sons Ltd.

    Heterogeneity in work outcomes is common among individuals with serious mental illness (SMI). In 2 studies, we sought to examine the efficacy of adding errorless learning, a behavioral training intervention, to evidence-based supported employment to improve SMI work outcomes. Work behavior problems were targeted for intervention. We also explored associations between early work behavior and job tenure. For both studies (VA: n = 71; community mental health center: n = 91), randomization occurred at the time of job obtainment with participants randomized (1:1) to either errorless learning plus ongoing supported employment or ongoing supported employment alone and then followed for 12 months. Dependent variables included job tenure, work behavior, and hours worked and wages earned per week. For the primary intent-to-treat analyses, data were combined across studies. Findings revealed that participants in the errorless learning plus supported employment group stayed on their jobs significantly longer than those in the supported employment alone group (32.8 vs 25.6 wk). In addition, differential treatment effects favoring errorless learning were found on targeted work behavior problems (50.5% vs 27.4% improvement from baseline to follow-up assessment). There were no other differential treatment effects. For the prediction analyses involving work behavior, social skills explained an additional 18.3% of the variance in job tenure beyond levels of cognition, symptom severity, and past work history. These data support errorless learning as an adjunctive intervention to enhance supported employment outcomes and implicate the relevance of workplace social difficulties as a key impediment to prolonged job tenure.

    To describe the long-term outcome of very preterm infants receiving prolonged sedation and/or analgesia and examine the relationship between prolonged sedation and/or analgesia and this long-term outcome. A prospective population-based study (Etude EPIdémiologique sur les Petits Ages GEstationnels [EPIPAGE]). To reduce bias, the propensity score method was used. Nine regions of France. The study population included very preterm infants of fewer than 33 weeks' gestational age, born in 1997, who received mechanical ventilation and/or surgery. Main Exposure Prolonged exposure to sedative and/or analgesic drugs in the neonatal period, defined as exposure of more than 7 days to sedative and/or opioid drugs. Presence of moderate or severe disability at 5 years of age. The analysis concerns 1572 premature infants who received mechanical ventilation for whom information about exposure to prolonged sedation and/or analgesia in the neonatal period was available. A total of 115 were exposed and 1457 were not exposed. There was no significant difference between the number of patients lost to follow-up from the group of very preterm infants who were exposed to prolonged sedation and/or analgesia and the group who were not. Exposed very preterm infants had severe or moderate disability at 5 years (41/97; 42%) more often than those who were not exposed (324/1248; 26%). After adjustment for gestational age and propensity score, this association was no longer statistically significant (adjusted relative risk, 1.0; 95% confidence interval, 0.8-1.2). Prolonged sedation and/or analgesia is not associated with a poor 5-year neurological outcome after adjustment for the propensity score.

    The purpose of this study was to evaluate the outcome, return to sporting activity, and postoperative articular cartilage and bony morphology of shoulders that underwent arthroscopic suture anchor repair of bony Bankart lesions. The inclusion criteria for this retrospective study were anterior glenoid rim fractures after traumatic shoulder instability that were treated with arthroscopic suture anchor repair. Patients were surveyed by a questionnaire including sport-specific outcome, Rowe score, Western Ontario Shoulder Instability Index, and Oxford Instability Score. Three-tesla magnetic resonance imaging could be performed in 30 patients to assess osseous integration, glenoid reconstruction, and signs of osteoarthritis. From November 1999 to April 2010, 81 patients underwent an anterior bony Bankart repair in our department (50 arthroscopic suture anchor repairs, 5 arthroscopic screw fixations, and 26 open repairs). The 55 arthroscopic repairs comprised a consecutive cohort of patients treated by a single surgeon. Of the 50 patients in the suture anchor group, 45 (90%) were available for evaluation. At 82 ± 31 months postoperatively, the mean Rowe score was 85.9 ± 20.5 points, the mean Western Ontario Shoulder Instability Index score was 89.4% ± 14.7%, and the mean Oxford Instability Score was 13.6 ± 5.4 points. Compared with the contralateral shoulder, all scores showed a significantly reduced outcome (P sporting activity after surgery. The number of sports disciplines (P < .001), duration (P = .005), level (P = .02), and risk category (P = .013) showed a significant reduction compared with the pretrauma condition. However, only 19% of patients reported that shoulder complaints were the reason for the reduction in activity. Nonunion occurred in 16.6%, with a higher frequency in patients with chronic lesions (P = .031). Anatomic reduction was achieved in 72%, the medial step-off in patients with nonanatomic reduction averaged 1.8 ± 0.9 mm, and the

Transvaginal ultrasound examination 12 weeks after uncomplicated successful bilateral placement or as indicated according to the transvaginal ultrasound protocol after 4 weeks, and hysterosalpingography (HSG) at 12 weeks to confirm correct placement of the device after 3 months. The rate of successful placement was 88.4% initially. In 164 women (15%), successful placement was confirmed at HSG according the protocol. In 9 patients (0.84%), incorrect position of the device was observed at HSG. The cumulative pregnancy rate after 18 months was 3.85 per thousand women. Transvaginal ultrasound should be the first diagnostic test used to confirm the adequacy of hysteroscopic Essure sterilization because it is minimally invasive, averts ionizing radiation, and does not decrease the effectiveness of the Essure procedure.

    Conflicting data exist on the impact on outcome of the use of different stent types during carotid artery stenting (CAS). The aim of this study was to evaluate clinical outcomes according to different carotid stent design among the population of the European Registry of Carotid Artery Stenting (ERCAS). The present study was conducted in 1,604 patients who underwent neuroprotected CAS in ERCAS. All types of commercially available carotid stent were used. Open-cell design stents were classified according to free cell area into 7.5 mm2. A total of 713 closed-cell, 456 hybrid-cell, 238 7.5 mm2 open-cell stents were implanted. Overall, the 30-day stroke and death rate was 1.37%. At 30 days, 19 strokes occurred (1.18%): eight in the group of patients treated with a closed-cell (1.12%), two in those with a hybrid-cell (0.44%), three in those with a 7.5 mm2 open-cell stent (3.05%) (p=0.045). Data of the present study suggest that, in the setting of neuroprotected CAS performed in high-volume centres by properly trained operators, the use of an open-cell design stent with a free cell area >7.5 mm2 may be associated with an increased 30-day stroke risk.

    The aim of the study was to compare the hospital management and direct costs of self-poisoning in six United Kingdom hospitals and to investigate whether hospital management influences outcome. This was a prospective descriptive study carried out at three teaching hospitals and three district general hospitals in North West England on adults (aged 16 or over) presenting to the study centres with deliberate self-poisoning over a 5-month period. Data were based on demographic and clinical characteristics, management of the current episode, direct costs and repetition of self-poisoning within 12 weeks of index episode. There were 1778 episodes of self-poisoning during the study period. There were marked differences in management between centres. There was a fivefold difference in the rate of admission to a medical bed (16.5%-81.3%), and a twofold difference in the rate of psychosocial assessment (28.5%-57.7%). These differences remained after adjustment for demographic and clinical factors. Hospital costs per episode varied from pound 228 to pound 422 and repetition rate ranged from 10% to 16%. Psychosocial assessment was associated with a twofold reduction in the risk of repetition. The marked variability of services for self-poisoning continue. It seems likely that this is having a detrimental effect on patient outcomes. Large scale intervention studies are required to inform both clinical practice and service provision.

    Survivors of severe traumatic brain injury have a great variety of impairments and participation restrictions. Detailed descriptions of their long-term outcome are critical. We aimed to assess brain injury outcome for subjects with traumatic brain injury in terms of the International classification of functioning, disability and health. Four-year follow-up of an inception cohort of adults with severe traumatic brain injury by using face-to-face interviews with patients and proxies. Among 245 survivors at 4 years, 147 were evaluated (80% male, mean age: 32.5±14.2 years at injury); 46 (32%) presented severe disability, 58 (40%) moderate disability, and 40 (28%) good recovery. Most frequent somatic problems were fatigue, headaches, other pain, and balance. One quarter of subjects had motor impairments. Rates of cognitive complaints ranged from 25 to 68%, the most frequent being memory, irritability, slowness and concentration. With the Hospital Anxiety and Depression Scale, 43% had anxiety and 25% depression. Overall, 79% were independent in daily living activities and 40 to 50% needed help for outdoor or organizational activities on the BICRO-39. Most had regular contacts with relatives or close friends but few contacts with colleagues or new acquaintances. Subjects spent little time in productive activities such as working, studying, looking after children or voluntary work. Quality of life on the QOLIBRI scale was associated with disability level (Plife. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    The objective of this study was to evaluate the effect of birth center (inborn versus outborn) on morbidity and mortality for preterm neonates (23 to 32 weeks) using data collected prospectively within a uniform protocol. Secondary analyses of data from the NEurologic Outcomes and Pre-emptive Analgesia In Neonates (NEOPAIN) trial (n=898) were performed to evaluate the effect of inborn versus outborn delivery on neonatal outcomes, including the occurrence of severe intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), chronic lung disease (CLD), and mortality. Outborn babies were more likely to have severe IVH (p=0.0005); this increased risk persisted after controlling for severity of illness. When adjustments for antenatal steroids were added, the effect of birth center was no longer significant. Neither the occurrences of PVL or CLD nor mortality were significantly different between the inborn and outborn infants. Outborn babies are more likely to have severe IVH than inborn babies, perhaps because their mothers are less likely to receive antenatal steroids. Improvements in antenatal steroid administration to high-risk women may substantially reduce neonatal morbidity.

    To investigate whether risk factors for suicide attempts differ in children and adolescents and to categorize adulthood mental health outcomes of child and adolescent suicide attempters in the general population. Using a large (N = 34,653), nationally representative US adult sample, the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions, we examined whether individuals who first attempted suicide during childhood (under the age of 13 years) differ from those who first attempted suicide during adolescence (13 through 17 years) in (1) contributing factors for first suicide attempt, including mental disorders and traumatic experiences that occurred before the first suicide attempt, parental history of mental disorders, and family poverty and (2) adulthood mental health outcomes, including lifetime and current prevalence of DSM-IV psychiatric disorders and quality of life measures. Suicide attempts during childhood (n = 104) were more strongly related to childhood maltreatment, while suicide attempts during adolescence (n = 415) were more strongly associated with major depressive episode. Compared to first suicide attempts during adolescence, first attempts during childhood were associated with increased risk for multiple suicide attempts (61.3% vs 32.6%), several psychiatric disorders (mania, hypomania, and panic disorder), and poorer social functioning during adulthood (all P values childhood maltreatment and early intervention for psychiatric disorders may have broad benefits to reduce not only the suffering of these children and adolescents, but also the burden of suicide. © Copyright 2017 Physicians Postgraduate Press, Inc.

    The aim of this paper is to evaluate the results of treatment of distal femoral fractures (DFF) fixed with locking plates and analysis of factors that influence the final outcome. The patients were treated at the Department of Traumatology and Orthopedics, Military Medical Institute in Warsaw, and the Department of Orthopedics and Traumatology, 4th Military Research Hospital in Wroclaw. We analysed 39 patients with 42 fractures of the distal femur. Treatment results were analysed using the KOOS and KSS scales. Factors influencing the outcome were also investigated. Statistical analysis was performed using STATISTICA v. 10. Mean KOOS scores indicate a predominance of poor outcomes, while mean KSS scores indicate good outcomes. Treatment outcomes were significantly influenced by pain and limited mobility. 1. Subjective evaluation of treatment of fractures of the distal femur using the KOOS scale per form edworse than a clinical evaluation using the KSS. 2. Post-operative management should emphasise pain relief and restoration of the performance of the treated lower limb to ensure good mobility without crutches. 3. Despite the use of modern operational methods of fracture fixation, treatment of distal femur fractures is still a challenge.

    Gerené, S. P. B.; Hummeling, R. W. J.; Ockels, W. J.

    A study is performed to investigate the feasibility of a manned expedition to the Moon using the European Ariane-5 launcher. The primary objective of this lunar mission is to confirm the presence of water at the South-Pole craters. It is believed that these permanently shadowed craters contain water in the form of ice. Secondary objective is to perform lunar surface science and making a first step towards a lunar outpost. Early results show that a minimum of two Ariane-5 launches is required. In this `two Ariane' scenario the first launch will bring a Lunar Landing Vehicle (LLV) into low lunar orbit. The second will launch two astronauts in a Crew Transfer Vehicle into a rendez- vous trajectory with the LLV. Arrived at the Moon, the astronauts will enter the LLV, undock from the CTV and land at the designated site located near the rim of the South-Pole Shackleton crater. The transfer strategy for both spacecraft will be the so-called direct transfer, taking about four days. At arrival the LLV will start mapping the landing site at a ground resolution of one meter. As a consequence of the polar orbit, the CTV has to arrive fourteen days later and surface operations can take about twelve days, accumulating in a total mission-duration of 36 days. 32 days for the CTV and 22 days for the LLV. In case a `two Ariane' flight does not posses sufficient capabilities also a `three Ariane' scenario is developed, in which the LLV is split-up into two stages and launched separately. These two will dock at the Moon forming a descent stage and an ascent stage. The third launch will be a CTV. During surface operations, astronauts will set up a solar power unit, install the sample retrieval system and carry out surface science. Samples of the crater floor will be retrieved by means of a probe or robot guided along a cable suspended over the crater rim. Also, this paper shows the way in which European astronauts can be brought to the Moon for other future missions, like the

    We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.=20

    This study examined parental factors associated with outcomes of youth in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial. Of 699 youth with type 2 diabetes in the TODAY cohort, 623 (89.1%) had a parent participate and provide data at baseline, including weight, HbA1c, blood pressure, symptoms of depression, binge eating (BE), and medical history. Youth were followed 2-6.5 years. Data were analyzed using regression models and survival curve methods. Parental diabetes (43.6% of parents) was associated with higher baseline HbA1c (P parent, P = 0.0002). Parental hypertension (40.6% of parents) was associated with hypertension in youth during TODAY (40.4% vs. 27.4% of youth with and without parental hypertension had hypertension, P = 0.0008) and with higher youth baseline BMI z scores (P = 0.0038). Parents had a mean baseline BMI of 33.6 kg/m(2). Parental obesity (BMI >30 kg/m(2)) was associated with higher baseline BMI z scores in the youth (P parents (20.6% of parents) were related to youth depressive symptoms at baseline only (P = 0.0430); subclinical BE in parents was related to the presence of subclinical BE (P = 0.0354) and depressive symptoms (P = 0.0326) in youth throughout the study period. Parental diabetes and hypertension were associated with lack of glycemic control, hypertension, and higher BMI z scores in youth. Further research is needed to better understand and address parental biological and behavioral factors to improve youth health outcomes. © 2015 by the American Diabetes Association.

    The study's purpose is to report the technical and clinical outcomes of a patient cohort that underwent vertebral artery ostium stent placement for atherosclerotic stenosis. We retrospectively analyzed a prospectively collected database of neurointerventional procedures performed at a single center from 1999 to 2005. Outcome measures included recurrent transient neurological deficits (TNDs), stroke, and death. Kaplan-Meier analysis was used to estimate stroke- and/or death-free survival at 12 months. Cox proportional hazard was used to identify risk factors for recurrent vertebrobasilar ischemic events. Seventy-two patients with 77 treated vertebral ostial lesions were included. The 30-day stroke and/or death rate was 5.2% (n = 4), although no event was directly related to the vertebral ostium stent placement. Three procedure-related strokes were secondary to attempted stent placement at other sites (one carotid artery and two basilar arteries), and the one death was secondary to the presenting stroke severity. The mean clinical follow-up time available for 66 patients was 9 months. There were 14 TNDs (21%), two strokes (3%), and two deaths (3%) recorded in the follow-up. Recurrent vertebrobasilar ischemic events occurred in nine patients (seven TNDs and two strokes). No recurrent stroke and/or deaths were related to the treated vertebral ostium. Stroke- and/or death-free survival rate (including periprocedural stroke and/or death) was 89 ± 5% at 12 months. No vascular risk factor was significantly associated with recurrent vertebrobasilar ischemic events. Vertebral artery ostium stent placement can be safely and effectively performed with a low rate of recurrent stroke in the territory of the treated vessel. Patients who also underwent attempted treatment of a tandem intracranial stenosis appeared to be at highest risk for periprocedure stroke. (orig.)

Experimental data from a nationally representative, longitudinal sample of smokers, collected in three waves over 4 weeks. National. Subjects. Three thousand and two adult U.S. smokers aged 18+ completed baseline and follow-up interviews at 2 and 4 weeks, from December 2010 to February 2011. Six randomly assigned conditions consisting of repeated exposure to cessation advertisements: why-to-quit advertisements featuring emotional, personal testimonies (1: WTQ-T) or graphic images (2: WTQ-G); how-to-quit advertisements (3: HTQ), a combination of both (4: WTQ-T + HTQ; 5: WTQ-G + HTQ), and no-ad condition (6: control). Cessation-related beliefs, attitudes, intentions, and quitting behavior. Multivariable ordinary least squares and logistic regressions testing whether exposure to antitobacco television advertisements were associated with changes in tobacco-related outcomes. Exposure to WTQ-T or WTQ-G advertisements, both alone and combined with HTQ advertisements, elicited positive change in beliefs, attitudes, and intentions as compared to controls. Smokers in three of four WTQ conditions were substantially more likely to have quit smoking at 4 weeks than controls (odds ratios range from 5.9 to 10.1, p advertisements markedly increases the odds that a smoker will quit in the study period, suggesting positive movement toward successful, long-term cessation. HTQ advertisements did not enhance advertising effectiveness and may not be suitable as a primary message strategy.

    Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder commonly associated with Attention Deficit Hyperactivity Disorder (ADHD), the prevalence ranging from 14-70%. The current study attempted to assess the impact of comorbid ADHD in children with ASD, in terms of challenges in diagnosis, treatment, intervention outcomes and parental stress and coping through a naturalistic design. Fifty children aged 2-6 years with ASD were recruited, assessed and followed up for six months. Twenty children were found to have comorbid ADHD. Severity of ASD and ADHD was assessed by Childhood Autism rating scale and Connor's abbreviated rating scale respectively. Parental stress and coping was assessed by Family Interview for stress and coping. The diagnosis of ASD was apparently obscured by ADHD symptoms in about 22% of cases, as only diagnosis of ADHD was made at the time of referral to our centre. ADHD was the most common comorbidity followed by intellectual disability and seizure disorder. About 66% of children received combination of pharmacological and behavioral interventions. Clonidine was the most common medication to be used and was well tolerated. The improvement in ADHD symptomatology showed positive correlation with improvement with ASD-specific interventions as reflected by change in severity scores. Severity of ADHD significantly also predicted parental stress and coping, and thereby engagement in ASD-specific interventions. The current study highlights the need for screening and early diagnosis of comorbid ADHD in children with ASD and vice versa considering the management challenges. In case of multiple comorbid neurodevelopmental disorders, early interventions for one disorder can improve the outcome of the other. Copyright © 2018 Elsevier B.V. All rights reserved.

    The purpose of this document is to identify and analyze the types of in-situ instruments and methods that could be used in support of the data acquisition portion of the Performance Confirmation (PC) program at the potential nuclear waste repository at Yucca Mountain. The PC program will require geomechanical , geophysical, thermal, and hydrologic instrumentation of several kinds. This analysis is being prepared to document the technical issues associated with each type of measurement during the PC period. This analysis utilizes the ''Performance Confirmation Input Criteria'' (CRWMS M andO 1999a) as its starting point. The scope of this analysis is primarily on the period after the start of waste package emplacement and before permanent closure of the repository, a period lasting between 15 and 300 years after last package emplacement (Stroupe 2000, Attachment 1, p. 1). The primary objectives of this analysis are to: (1) Review the design criteria as presented in the ''Performance Confirmation Input Criteria'' (CRWMS M andO 1999a). The scope of this analysis will be limited to the instrumentation related to parameters that require continuous monitoring of the conditions underground. (2) Preliminary identification and listing of the data requirements and parameters as related to the current repository layout in support of PC monitoring. (3) Preliminary identification of methods and instrumentation for the acquisition of the required data. Although the ''Performance Confirmation Input Criteria'' (CRWMS M andO 1999a) defines a broad range of data that must be obtained from a variety of methods, the focus of this analysis is on instrumentation related to the performance of the rock mass and the formation of water in the repository environment, that is obtainable from in-situ observation, testing, and monitoring

    Heat flux in weakly magnetized collisionless plasma is, according to theoretical predictions, limited by whistler turbulence that is generated by heat flux instabilities near threshold. Observations of solar wind electrons by Gary and coworkers appear to confirm the limit on heat flux as being roughly the product of the magnetic energy density and the electron thermal velocity, in agreement with prediction (Pistinner and Eichler 1998)

    90% of the global burden of injuries is borne by low-income and middle-income countries (LMICs). However, details of the injury burden in LMICs are less clear because of the scarcity of data and population-based studies. The Saving of Lives from Drowning project, implemented in rural Bangladesh, did a census on 1·2 million people to fill this gap. This Article describes the epidemiology of fatal and non-fatal injuries from the study. In this study, we used data from the baseline census conducted as part of the Saving of Lives from Drowning (SoLiD) project. The census was implemented in 51 unions from seven purposively sampled rural subdistricts of Bangladesh between June and November, 2013. Sociodemographic, injury mortality, and morbidity information were collected for the whole population in the study area. We analysed the data for descriptive measures of fatal and non-fatal injury outcomes. Age and gender distribution, socioeconomic characteristics, and injury characteristics such as external cause, intent, location, and body part affected were reported for all injury outcomes. The census covered a population of 1 169 593 from 270 387 households and 451 villages. The overall injury mortality rate was 38 deaths per 100 000 population per year, and 104 703 people sustained major non-fatal injuries over a 6-month recall period. Drowning was the leading external cause of injury death for all ages, and falls caused the most number of non-fatal injuries. Fatal injury rates were highest in children aged 1-4 years. Non-fatal injury rates were also highest in children aged 1-4 years and those aged 65 years and older. Males had more fatal and non-fatal injuries than females across all external causes except for burns. Suicide was the leading cause of injury deaths in individuals aged 15-24 years, and more than 50% of the suicides occurred in females. The home environment was the most common location for most injuries. The burden of fatal and non-fatal injuries

    Indoleamine 2,3-dioxygenase (IDO) metabolizes tryptophan to kynurenine. An increase of its activity is associated with severity in patients with pneumonia. In chronic obstructive pulmonary disease (COPD) patients, an elevation of serotonin has been reported. Experimental models showed that cigarette smoke inhibits monoamine oxidase (MAO) leading to higher levels of serotonin. We investigated the prognostic ability of tryptophan, serotonin, kynurenine, IDO, and tryptophan hydroxylase (TPH) to predict short- and long-term outcomes in patients with a COPD exacerbation. We measured tryptophan, serotonin, and kynurenine on admission plasma samples in patients with a COPD exacerbation from a previous trial by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). IDO and TPH were calculated as ratios of kynurenine over tryptophan, and serotonin over tryptophan, respectively. We studied their association with parameters measured in clinical routine at emergency department admission representing inflammation (C-reactive protein [CRP]), infection (procalcitonin [PCT]), oxygenation (SpO 2 ), as well as patients' clinical outcome, confirmed by structured phone interviews. Mortality in the 149 included patients was 53.7% within six years of follow-up. While IDO activity showed strong positive correlations, tryptophan was negatively correlated with CRP and PCT. For 30-day adverse outcome defined as death and/or intensive care unit (ICU) admission, a multivariate regression analysis adjusted for age and comorbidities found strong associations for IDO activity (adjusted odds ratios of 31.4 (95%CI 1.1-857), p = 0.041) and TPH (adjusted odds ratios 27.0 (95%CI 2.2-327), p = 0.010). TPH also showed a significant association with mortality at 18 months, (hazard ratio 2.61 (95%CI 1.2-5.8), p = 0.020). In hospitalized patients with a COPD exacerbation, higher IDO and TPH activities independently predicted adverse short-term outcomes and TPH levels were also

    To present a novel and simple graphical approach to improve the presentation of the treatment ranking in a network meta-analysis (NMA) including multiple outcomes. NMA simultaneously compares many relevant interventions for a clinical condition from a network of trials, and allows ranking of the effectiveness and/or safety of each intervention. There are numerous ways to present the NMA results, which can challenge their interpretation by research users. The rank-heat plot is a novel graph that can be used to quickly recognize which interventions are most likely the best or worst interventions with respect to their effectiveness and/or safety for a single or multiple outcome(s) and may increase interpretability. Using empirical NMAs, we show that the need for a concise and informative presentation of results is imperative, particularly as the number of competing treatments and outcomes in an NMA increases. The rank-heat plot is an efficient way to present the results of ranking statistics, particularly when a large amount of data is available, and it is targeted to users from various backgrounds.

    Atypical clinical presentation in acute myocardial infarction (AMI) patients is not uncommon; most studies suggest that it is associated with unfavorable prognosis. Long-term clinical impact differs according to predominant symptom presentation (typical chest pain, atypical chest pain, syncope, cardiac arrest, or dyspnea) in AMI patients. FAST-MI 2010, a nationwide French registry, included 4169 patients with AMI in 213 centers at the end of 2010 (76% of active centers). Demographics, medical history, hospital management, and outcomes were compared according to predominant symptom presentation. Typical chest pain with no other symptom was reported in 3020 patients (68% in STEMI patients, 76% in NSTEMI patients). Atypical chest pain, dyspnea, syncope, and cardiac arrest were reported in 11%, 11%, 5%, and 1%, respectively. Patients with atypical clinical presentation had a higher cardiovascular risk profile and received fewer medications and a less invasive strategy. Using Cox multivariate analysis, atypical chest pain was not associated with higher death rate at 3 years (HR: 0.96, 95% CI: 0.69-1.33, P = 0.78), whereas cardiac arrest (HR: 2.44, 95% CI: 1.00-5.97, P = 0.05), syncope (HR: 1.70, 95% CI: 1.18-2.46, P = 0.005), and dyspnea (HR: 1.66, 95% CI: 1.31-2.10, P clinical presentation is observed in about 20% of AMI patients. Cardiac arrest, dyspnea, and syncope represent independent predictors of long-term mortality in STEMI and NSTEMI populations. © 2017 Wiley Periodicals, Inc.

    The cardiovascular safety of sitagliptin has been evaluated in TECOS ("Trial Evaluating Cardiovascular Outcomes with Sitagliptin"). TECOS recruited patients with type 2 diabetes and a history of cardiovascular disease who received, as add-on to their usual therapy, either sitagliptin (n = 7.257) or placebo (n = 7.266), with a median follow-up of 3 years. The primary cardiovascular outcome was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina. Sitagliptin was noninferior to placebo for the primary composite cardiovascular outcome (hazard ratio, 0.98; 95% confidence interval, 0.88 to 1.09; P<0.001). Rates of hospitalization for heart failure did not differ between the two groups (hazard ratio, 1.00; 95% CI, 0.83 to 1.20; P=0.98). The cardiovascular safety of sitagliptin, which was already shown in meta-analyses of phase II-III randomised controlled trials and in observational cohort studies in real life, is now confirmed in the landmark prospective cardiovascular outcome study TECOS.

    Full Text Available Evidence to guide clinical management of self-harm is sparse, trials have recruited selected samples, and psychological treatments that are suggested in guidelines may not be available in routine practice.To examine how the management that patients receive in hospital relates to subsequent outcome.We identified episodes of self-harm presenting to three UK centres (Derby, Manchester, Oxford over a 10 year period (2000 to 2009. We used established data collection systems to investigate the relationship between four aspects of management (psychosocial assessment, medical admission, psychiatric admission, referral for specialist mental health follow up and repetition of self-harm within 12 months, adjusted for differences in baseline demographic and clinical characteristics.35,938 individuals presented with self-harm during the study period. In two of the three centres, receiving a psychosocial assessment was associated with a 40% lower risk of repetition, Hazard Ratios (95% CIs: Centre A 0.99 (0.90-1.09; Centre B 0.59 (0.48-0.74; Centre C 0.59 (0.52-0.68. There was little indication that the apparent protective effects were mediated through referral and follow up arrangements. The association between psychosocial assessment and a reduced risk of repetition appeared to be least evident in those from the most deprived areas.These findings add to the growing body of evidence that thorough assessment is central to the management of self-harm, but further work is needed to elucidate the possible mechanisms and explore the effects in different clinical subgroups.

    The overall incidence of common bile duct strictures due to chronic pancreatitis is reported to be approximately 10-30%. It remains a challenging problem for gastroenterologists and surgeons. The exact role of endoscopic stenting has not yet been clearly defined. Thirty-nine patients with chronic pancreatitis and symptomatic common bile duct stenoses underwent endoscopic stenting and were studied retrospectively. We were particularly interested in how many patients would achieve resolution of the stricture and tolerate removal of the stents in the long term. Indications for endoscopic stenting were symptomatic cholestasis, jaundice or cholangitis. The initial serum bilirubin was 8.3 mg/dl and the diameter of the common bile duct was 14.2 mm before stenting. Within 3-7 days of stenting, all patients presented improvement of jaundice and cholestasis. After a median stenting time of 9 months (range 1-144 months), 46% of the patients demonstrated regression of the stricture and clinical improvement, 26% required further stenting, and 28% were referred to surgery. Five patients received a self-expandable metal Wallstent. Thirty-one per cent demonstrated complete clinical recovery of the stricture as well as 10.2% a complete, radiologically verified stricture regression in a median follow-up of 58 months. There seems to be a therapeutic benefit for short-term endoscopic treatment but medium-term and long-term outcome remains questionable. Endoscopic stenting should be applied as an initial therapy before surgery, but it can be the definitive approach for older and morbid patients or cases with complete stricture regression after stent removal. Overall, it should not be considered as a routine procedure for symptomatic cases.

    To evaluate the impact of obesity on adverse events and required interventions during pediatric procedural sedation. The Pediatric Sedation Research Consortium database of prospectively collected procedural sedation encounters was queried to identify patients for whom body mass index (BMI) could be calculated. Obesity was defined as BMI ≥95th percentile for age and gender. Sedation-related outcomes, adverse events, and therapeutic interventions were compared between obese and nonobese patients. For analysis, 28,792 records were eligible. A total of 5,153 patients (17.9%) were obese; they were predominantly male and older and had a higher median American Society of Anesthesiologists Physical Status classification (P obese patients (odds ratio [OR] 1.49, 95% confidence interval [1.31, 1.70]). Respiratory events (airway obstruction OR 1.94 [1.54, 2.44], oxygen desaturation OR 1.99 [1.50, 2.63], secretions OR 1.48 [1.01, 2.15], laryngospasm OR 2.30 [1.30, 4.05]), inability to complete the associated procedure (OR 1.96 [1.16, 3.30]), and prolonged recovery (OR 2.66 [1.26, 5.59]) were increased in obese patients. Obese patients more frequently required airway intervention including repositioning, suctioning, jaw thrust, airway adjuncts, and bag-valve-mask ventilation. Multivariate regression analysis demonstrated obesity to be independently associated with minor and moderate but not major adverse events. Obesity is an independent risk factor for adverse respiratory events during procedural sedation and is associated with an increased frequency of airway interventions, suggesting that additional vigilance and expertise are required when sedating these patients. © 2015 John Wiley & Sons Ltd.

    To assess neurodevelopmental outcomes among participants with biliary atresia with their native liver at ages 12 months (group 1) and 24 months (group 2), and to evaluate variables predictive of neurodevelopmental impairment. Participants enrolled in a prospective, longitudinal, multicenter study underwent neurodevelopmental testing with either the Bayley Scales of Infant Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition. Scores (normative mean = 100 ± 15) were categorized as ≥100, 85-99, and Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition, scales) was analyzed using logistic regression. There were 148 children who completed 217 Bayley Scales of Infant and Toddler Development, 3rd edition, examinations (group 1, n = 132; group 2, n = 85). Neurodevelopmental score distributions significantly shifted downward compared with test norms at 1 and 2 years of age. Multivariate analysis identified ascites (OR, 3.17; P = .01) and low length z-scores at time of testing (OR, 0.70; P cognitive/language impairment at 1 year of age. An unsuccessful hepatoportoenterostomy was predictive of both physical/motor (OR, 4.88; P cognitive/language impairment (OR, 4.76; P = .02) at 2 years of age. Participants with biliary atresia surviving with native livers after hepatoportoenterostomy are at increased risk for neurodevelopmental delays at 12 and 24 months of age. Those with unsuccessful hepatoportoenterostomy are >4 times more likely to have neurodevelopmental impairment compared with those with successful hepatoportoenterostomy. Growth delays and/or complications indicating advanced liver disease should alert clinicians to the risk for neurodevelopmental delays, and expedite appropriate interventions.

    This patient presented with generalized severe chronic periodontitis. Conventional periodontal therapy would have left her compromised esthetically and anatomically, with growing interdental "black triangles." This prompted the authors to try to reconstruct the maxillary alveolar bone that had been lost in the previous three decades because of untreated periodontitis. To maintain the level and quality of the gingival margin, open flap surgery was performed in the maxilla soon after scaling and root planing. To gain access to the roots and bone surfaces, a flap was raised by intrasulcular incisions and the modified and simplified papilla preservation technique. After debridement, the root surfaces were conditioned and enamel matrix proteins were applied. Bovine bone mineral was placed in the infrabony defects and supracrestally (buccally, lingually, and interdentally) to help regenerate the lost alveolar bone. In addition, the defects around the maxillary anterior teeth were covered with a membrane. To prevent shrinkage of the gingiva, suspensory sutures were placed on the right central incisor and both left incisors so that the anterior flap would be positioned approximately 3 mm coronally. After surgery, the patient was advised to apply 1% chlorhexidine gel twice a day and to avoid brushing the surgical site for 4 weeks. Professional maintenance care was administered twice a week for 2 months and the patient was instructed to maintain a liquid diet for 4 weeks. The treatment outcome was evaluated clinically and radiographically at regular intervals for 5 years postsurgically. Periodontal conditions were stable and fulfilled the patient's desire to eliminate the pockets without compromising esthetics, particularly in the maxillary anterior.

    In 2008, the Irish Government initiated a pilot Healthy Schools Programme based on the World Health Organization Health Promoting Schools Model among children attending schools officially designated as urban and disadvantaged. We present here the first results on physical and emotional health and the relationship between childhood depression and demographic and socioeconomic factors. The Healthy Schools Programme evaluation was a 3-year longitudinal outcome study among urban disadvantaged children aged 4 to 12 years. Physical and psychological health outcomes were measured using validated, international instruments at baseline. Outcomes at baseline were compared with international norms and where differences were found, results were statistically modeled to determine factors predicting poor outcomes. A total of 552 children responded at baseline, representing over 50% of all eligible children available to participate from 7 schools. Findings at baseline revealed that in general, children did not differ significantly from international norms. However, detailed analysis of the childhood depression scores revealed that in order of importance, psychological well-being, the school environment, social support, and peer relations and age were statistically significant predictors of increased childhood depression in children under 12 years of age. Future health and well-being studies in schools among urban disadvantaged children need to broaden their scope to include measures of depression in children under 12 years of age and be cognisant of the impact of the school environment on the mental and emotional health of the very young. © 2012, American School Health Association.

    Student learning outcome is an important dimension of teaching quality in undergraduate medical education. Measuring an increase in knowledge during teaching requires repetitive objective testing which is usually not feasible. As an alternative, student learning outcome can be calculated from student self-ratings. Comparative self-assessment (CSA) gain reflects the performance difference before and after teaching, adjusted for initial knowledge. It has been shown to be a valid proxy measure of actual learning outcome derived from objective tests. However, student self-ratings are prone to a number of confounding factors. In the context of outcome-based evaluation, the wording of self-rating items is crucial to the validity of evaluation results. This randomized trial assessed whether including qualifiers in these statements impacts on student ratings and CSA gain. First-year medical students self-rated their initial (then-test) and final (post-test) knowledge for lectures in anatomy, biochemistry and legal medicine, respectively, and 659 questionnaires were retrieved. Six-point scales were used for self-ratings with 1 being the most positive option. Qualifier use did not affect then-test ratings but was associated with slightly less favorable post-test ratings. Consecutively, mean CSA gain was smaller for items containing qualifiers than for items lacking qualifiers (50.6±15.0% vs. 56.3±14.6%, p=0.079). The effect was more pronounced (Cohen's d=0.82) for items related to anatomy. In order to increase fairness of outcome-based evaluation and increase the comparability of CSA gain data across subjects, medical educators should agree on a consistent approach (qualifiers for all items or no qualifiers at all) when drafting self-rating statements for outcome-based evaluation.

    2004-01-01

    In an ongoing effort to improve quality of the repair requests, a new e-mail confirmation automatic system will be implemented starting from the 21st October. All repair requests transmitted to the TCR (72201) or the FM Helpdesk (77777) will be confirmed in an e-mail to the requestor, provided that the latter has a valid e-mail address in the HR database. The e-mail will contain a reference number, a brief description of the problem, the location and a contact where more information can be obtained. A second e-mail will be sent when the processing of the repair request is finished. We hope that this initiative will improve the transparency and quality of our service. Helpdesk Troubleshooting Requests (reminder) We remind you that all the repair requests and other communication concerning the CERN machine buildings have to be transmitted to the TCR via 72201, whereas the ones concerning tertiary buildings are handled directly by the FM helpdesk under the phone number 77777, i.e. problems on systems and equ...

  15. Kepler Confirmation of Multi-Planet Systems

    2011-10-01

    The NASA Kepler spacecraft has detected 170 candidate multi-planet systems in the first two quarters of data released in February 2011 by Borucki et al. (2011). These systems comprise 115 double candidate systems, 45 triple candidate sys- tems, and 10 systems with 4 or more candidate planets. The architecture and dynamics of these systems were discussed by Lissauer et al. (2011), and a comparison of candidates in single- and multi-planet systems was presented by Latham et al. (2011). Proceeding from "planetary candidate" systems to confirmed and validated multi-planet systems is a difficult process, as most of these systems orbit stars too faint to obtain extremely precise (1ms-1) radial velocity confimation. Here, we discuss in detail the use of transit timing vari- ations (cf. e.g. Holman et al., 2010) to confirm planets near a mean motion resonance. We also discuss extensions to the BLENDER validation (Torres et al., 2004, 2011; Fressin et al., 2011) to validate planets in multi-planet systems. Kepler was competitively selected as the tenth Discovery mission. Funding for the Kepler Mis- sion is provided by NASA's Science Mission Direc- torate. We are deeply grateful for the very hard work of the entire Kepler team.

    To evaluate the 2-year outcomes of uveitic macular edema. Longitudinal follow-up of a randomized cohort. At baseline, 148 eyes of 117 patients enrolled in the Multicenter Uveitis Steroid Treatment (MUST) Trial had macular edema, and 134 eyes of 108 patients completed 2-year follow-up. Patients enrolled in the study were randomized to either systemic immunosuppression or intravitreal fluocinolone acetonide implant therapy. Macular edema was defined as thickening of the retina (center point thickness≥240 μm) on time-domain optical coherence tomography (OCT) of macula. Improvement in macular edema (≥20% reduction in central point thickness on OCT), resolution of macular edema (normalization of thickness on OCT), and best-corrected visual acuity (BCVA). Between randomization and 2-years' follow-up, 62% and 25% of eyes in the systemic and implant groups, respectively, received at least 1 supplemental regional corticosteroid injection. By 2-years' follow-up, macular edema improved in 71% of eyes and resolved in 60%. There were no differences between treatment groups in the proportion of eyes with macular edema improving (systemic therapy vs. implant, 65% vs. 77%; P=0.20) and resolving (52% vs. 68%; P=0.28), but eyes randomized to implant had more improvement in macular thickness (median decrease of 180 vs. 109 μm in the systemic therapy group; P=0.04). Eyes with baseline fluorescein angiographic leakage were more likely to improve than those without (76% vs. 58%; P=0.03). Overall, there was a mean 5-letter (1 line) improvement in BCVA at 2 years. Mean changes in BCVA from baseline at 2 years by macular edema response status were: resolution, +10 letters; improvement without resolution, +10 letters (P=0.92); little to no change, 6 letters (P=0.19); and worsening, -16 letters (worsening acuity; P=0.0003). About two thirds of eyes with uveitic macular edema were observed to experience improvement in the edema and visual acuity with implant or systemic treatment

    Purpose. To assess the predictive value of immediate angiographic results after percutaneous transluminal angioplasty (PTA) for stenoses in femoral bypass grafts using duplex ultrasound (DUS) criteria. Methods. A 1-year follow-up with DUS was performed in 38 patients with 50 stenoses in 41 grafts, treated with PTA for a graft stenosis. The indication for PTA according to DUS criteria was a severe stenosis in 43 lesions, and a moderate stenosis in 7 lesions. In the moderate stenosis group 3 patients showed claudication and 1 patient had a nonhealing ulcer. For the purposes of statistical evaluation, primary patency was considered present if the graft was not occluded. The graft was considered to have failed when it was found to be occluded on DUS, or when secondary interventions (surgery, repeat PTA) were performed. Results. After 1 year the cumulative primary patency rate was 44$ [95% confidence interval (CI) 27.8-59.8]. Stenoses with initially good angiographic results after PTA (<30% residual stenosis) were 2.9 times more likely to be patent at 1 year than stenoses with initially poor or moderate angiographic results (hazard ratio 2.9, 95% CI 1.3-6.4,p=0.007). Conclusion. A poor or moderate angiographic result immediately following PTA was prognostic for poor long-term results and may indicate a requirement for earlier surgical intervention

    The health information system in Catalonia has experienced an important evolution but obtaining integrated data to evaluate the health services is still difficult. At the end of 2008 the basis of the information system of the "Center of Results" and a first set of indicators has been approved by the health system stakeholders. The "Center of Results" is assigned to the Catalan Health Service. It has a Direction Board and a Technical Committee to regulate its operation. The "Center of Results" has the mission to measure, evaluate and disseminate the results obtained in health care by the members of the public health services, to facilitate decision making with shared responsibility at the service of the quality of the health care given to the citizens of Catalonia. The "Center of Results" is based on performance principles that determine their operation: to share and to coordinate the existing information, to stimulate the participation and the co-responsibility of the implied agents, continuous improvement of the health information, promotion of good practices in the use of information and its responsible use, efficient instrumentation of technologies and analytical capacity to transform data into information. A participative process has been made to select and prioritize indicators. This process has reached consensus on a set of indicators. These indicators must contribute to assess the impact of the interventions of the health system on the level of the population's health and how results, with an efficient use of the resources, are obtained. 2010 Elsevier España S.L.

  20. Boosted classification trees result in minor to modest improvement in the accuracy in classifying cardiovascular outcomes compared to conventional classification trees

    Austin, Peter C; Lee, Douglas S

    2011-01-01

    Purpose: Classification trees are increasingly being used to classifying patients according to the presence or absence of a disease or health outcome. A limitation of classification trees is their limited predictive accuracy. In the data-mining and machine learning literature, boosting has been developed to improve classification. Boosting with classification trees iteratively grows classification trees in a sequence of reweighted datasets. In a given iteration, subjects that were misclassified in the previous iteration are weighted more highly than subjects that were correctly classified. Classifications from each of the classification trees in the sequence are combined through a weighted majority vote to produce a final classification. The authors' objective was to examine whether boosting improved the accuracy of classification trees for predicting outcomes in cardiovascular patients. Methods: We examined the utility of boosting classification trees for classifying 30-day mortality outcomes in patients hospitalized with either acute myocardial infarction or congestive heart failure. Results: Improvements in the misclassification rate using boosted classification trees were at best minor compared to when conventional classification trees were used. Minor to modest improvements to sensitivity were observed, with only a negligible reduction in specificity. For predicting cardiovascular mortality, boosted classification trees had high specificity, but low sensitivity. Conclusions: Gains in predictive accuracy for predicting cardiovascular outcomes were less impressive than gains in performance observed in the data mining literature. PMID:22254181

The results from mandatory cardiovascular outcome trials (CVOTs are therefore of great interest in the field. The Academy for Cardiovascular Risk, Outcomes and Safety Studies in Type 2 Diabetes meeting program aims to bring together experts from several associated disciplines to provide fair and balanced resources for those involved in the management of patients with T2D. This publication represents the opinions of the faculty on the key learnings from the meeting held in Vienna in the spring of 2017. In particular, we detail how data from the EMPA-REG OUTCOME® [cardiovascular outcomes trial of empagliflozin] and Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER® (liraglutide CVOTs can be practically interpreted across clinical specialities. It is hoped that this translation of CVOT data will achieve a dual treatment paradigm for the management of both raised glucose levels and CV risk in patients with T2D.

    Full Text Available A prevalence study was carried to isolate Salmonella typhimurium from blood (n= 50 and gut samples (n=100 of poultry in Kathmandu valley during early 2016. Salmonella typhimurium bacteria isolated in the selective media were biochemically confirmed based on Bergey’s Manual. Two sets of oligonucleotide primers-the genus specific 16S rRNA and the organism specific invA were employed for molecular level confirmation by the Polymerase Chain Reaction (PCR assay. The amplified fragments in 1% agarose gel observed at 406bp and 285bp, respectively confirmed the isolates to be Salmonella typhimurium. Of 150 samples tested, Salmonella typhimurium were isolated from 49 samples, among which nine were from blood (18% and forty from the gut (40%. The present result indicated an alarmingly high level of Salmonella typhimurium, which can result inzoonotic infection in humans owing to increased contact with poultry and consumption of poultry products in the Kathmandu valley.

    -to-face setting was developed. Interviewers asked service users to comment on how far their mental disorder has affected key areas of their lives, including work, marriage and partnerships, housing, leisure, and religious activities. For country-level information, staff at each national site gathered the best available data on whether special legal, policy or administrative arrangements are made for people with a diagnosis of mental illness. These items included, for example, information on access to insurance, financial services, driving licenses, voting, jury service, or travel visas. The INDIGO study is conducted within the framework of the WPA global program to fight stigma and discrimination because of schizophrenia. French interviews occurred in two sites (Lille and Nice) on a sample of 25 patients. First, expressed disadvantages are high for several items (all relations, work and training, housing). In addition, we wish to highlight three specific points: almost half of the participants (46%) suffer from not being respected because of contacts with services, 88% of them felt rejected by people who know their diagnosis, and 76% hide/conceal their diagnosis. Positive experienced discrimination was rare. Two thirds of participants anticipated discrimination for job seeking and close personal relationships, sometimes with no experienced discrimination. This study, one of the rare in France adopting the point of view of a stigmatized group, revealed the numerous impacts of a diagnosis of schizophrenic disorders on everyday life. Comparisons between French and international results confirmed that the situation is not different in France, and even highlighted the extent of the stigmatization in the country.

    The objective of this study was to evaluate, in a real-world context, the impact of race on disease recurrence and survival in patients with nonmetastatic triple-negative breast cancer (TNBC) treated with adjuvant chemotherapy. The study selected patients from the 2003-2008 Georgia Cancer Specialist Database with stage I-III confirmed TNBC who had received adjuvant chemotherapy. These patients were followed-up from initial diagnosis to death, cancer recurrence, or loss to follow-up. The primary outcome was disease-free survival (DFS). Kaplan-Meier curves compared DFS and recurrence between African American and non-African American groups. The impact of African American status was examined further through multivariate Cox models by adjusting for age, comorbidity, body mass index (BMI), smoking status, initial TNBC stage, surgery, and radiation therapy. Among 209 patients with TNBC, 89 (42.6%) were African American. The 2 groups (African American vs. non-African American) were similar in mean age at diagnosis (53.2 vs. 54.4 years; P =.487) and with surgery and radiation rates (98.9% vs. 100%; P = .244; 68.5% vs. 62.5%; P = .365, respectively). Compared with non-African Americans, African American patients had a higher BMI (30.4 vs. 28.6 kg/m(2); P = .0477) and were less likely to be diagnosed at stage I (31.5% vs. 51.7%; P = .0107). The African American patients had a lower 5-year DFS rate (45.2% vs. 79.7%; P = .0005) and a higher 5-year recurrence rate (42.5% vs. 7.0%; P = .0005) compared with the non-African American patients. Among patients with TNBC treated with adjuvant chemotherapy, African American race was associated with a worse outcome irrespective of later stage at presentation or higher BMI.

    OBJECTIVE Although various predictors of postoperative outcome have been previously identified in patients with Chiari malformation Type I (CMI) with syringomyelia, there is no known algorithm for predicting a multifactorial outcome measure in this widely studied disorder. Using one of the largest preoperative variable arrays used so far in CMI research, the authors attempted to generate a formula for predicting postoperative outcome. METHODS Data from the clinical records of 82 symptomatic adult patients with CMI and altered hindbrain CSF flow who were managed with foramen magnum decompression, C-1 laminectomy, and duraplasty over an 8-year period were collected and analyzed. Various preoperative clinical and radiological variables in the 57 patients who formed the study cohort were assessed in a bivariate analysis to determine their ability to predict clinical outcome (as measured on the Chicago Chiari Outcome Scale [CCOS]) and the resolution of syrinx at the last follow-up. The variables that were significant in the bivariate analysis were further analyzed in a multiple linear regression analysis. Different regression models were tested, and the model with the best prediction of CCOS was identified and internally validated in a subcohort of 25 patients. RESULTS There was no correlation between CCOS score and syrinx resolution (p = 0.24) at a mean ± SD follow-up of 40.29 ± 10.36 months. Multiple linear regression analysis revealed that the presence of gait instability, obex position, and the M-line-fourth ventricle vertex (FVV) distance correlated with CCOS score, while the presence of motor deficits was associated with poor syrinx resolution (p ≤ 0.05). The algorithm generated from the regression model demonstrated good diagnostic accuracy (area under curve 0.81), with a score of more than 128 points demonstrating 100% specificity for clinical improvement (CCOS score of 11 or greater). The model had excellent reliability (κ = 0.85) and was validated with

    Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. The study aimed to estimate the public health burden resulting from adverse pregnancy outcomes due to syphilis infection among pregnant women not screened for syphilis in 43 countries in sub-Saharan Africa. Estimated country-specific incidence of syphilis was generated from annual number of live births, the proportion of women with at least 1 antenatal care (ANC) visit, the syphilis prevalence rate, and the proportion of women screened for syphilis during ANC.Adverse pregnancy outcome data (stillbirth, neonatal death, low birth weight, and congenital syphilis) were obtained from published sources. Disability-adjusted life-year (DALY) estimates were calculated using undiscounted local life expectancy, the neonatal standard loss function, and relevant disability weights. The model assessed the potential impact of raising ANC coverage to at least 95% and syphilis screening to at least 95% (World Health Organization targets). For all 43 sub-Saharan Africa countries, the estimated incidence of adverse pregnancy outcomes was 205,901 (95% confidence interval [CI], 113,256-383,051) per year, including stillbirth (88,376 [95% CI, 60,854-121,713]), neonatal death (34,959 [95% CI, 23,330-50,076]), low birth weight (22,483 [95% CI, 0-98,847]), and congenital syphilis (60,084 [95% CI, 29,073-112,414]), resulting in approximately 12.5 million DALYs. Countries with the greatest burden are (in DALYs, millions) Democratic Republic of the Congo (1.809), Nigeria (1.598), Ethiopia (1.466), and Tanzania (0.961). Attaining World Health Organization targets could reduce the burden by 8.5 million DALYs. Substantial infant mortality and morbidity results from maternal syphilis infection concentrated in countries with low access to ANC or low rates of syphilis screening.

    To establish the value of breathhold magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis. Over a 14-month period, 138 patients clinically suspected of having appendicitis were evaluated prospectively with MRI and comprised the study group. Fast turbo spin-echo breathhold T1, T2 and T2 fat suppression sequences were used in coronal and axial planes. The imaging results were recorded separately and subsequently correlated with clinical, radiological and histopathological follow-up. The effect of imaging strategies in patients suspected of appendicitis on hospital resources was calculated. Sixty-two of the 138 patients had a histopathologically proven appendicitis. MRI determined appendicitis in 63 patients, with one examination being false positive. The resulting sensitivity and specificity were 100% and 99%, respectively. MRI showed an alternative diagnosis in 41 of the 75 remaining patients. In 22 of the remaining 34 patients, a normal appendix was depicted with MRI. In two patients, where MRI showed no appendicitis, an alternative diagnosis or normal appendix, an unnecessary appendectomy was performed. The overall effect of using MRI in patients suspected of appendicitis on the use of hospital resources could have been a net saving between EUR 55,746 and EUR 72,534. MRI has a high accuracy in detecting and excluding appendicitis, an alternative diagnosis or showing the normal appendix, and can be a valuable and cost-effective tool in the workup of patients clinically suspected of having appendicitis.

  13. Alternate Directed Anthropogenic Shifts in Genotype Result in Different Ecological Outcomes in Coho Salmon Oncorhynchus kisutch Fry.

    Rosalind A Leggatt

    Full Text Available Domesticated and growth hormone (GH transgenic salmon provide an interesting model to compare effects of selected versus engineered phenotypic change on relative fitness in an ecological context. Phenotype in domestication is altered via polygenic selection of traits over multiple generations, whereas in transgenesis is altered by a single locus in one generation. These established and emerging technologies both result in elevated growth rates in culture, and are associated with similar secondary effects such as increased foraging, decreased predator avoidance, and similar endocrine and gene expression profiles. As such, there is concern regarding ecological consequences should fish that have been genetically altered escape to natural ecosystems. To determine if the type of genetic change influences fitness components associated with ecological success outside of the culture environments they were produced for, we examined growth and survival of domesticated, transgenic, and wild-type coho salmon fry under different environmental conditions. In simple conditions (i.e. culture with unlimited food, transgenic fish had the greatest growth, while in naturalized stream tanks (limited natural food, with or without predators domesticated fish had greatest growth and survival of the three fish groups. As such, the largest growth in culture conditions may not translate to the greatest ecological effects in natural conditions, and shifts in phenotype over multiple rather than one loci may result in greater success in a wider range of conditions. These differences may arise from very different historical opportunities of transgenic and domesticated strains to select for multiple growth pathways or counter-select against negative secondary changes arising from elevated capacity for growth, with domesticated fish potentially obtaining or retaining adaptive responses to multiple environmental conditions not yet acquired in recently generated transgenic

    To report a subgroup analysis of the prospective, multicenter, single-arm DEFINITIVE LE trial to assess the effectiveness of directional atherectomy for the treatment of infrapopliteal artery lesions at 1 year. In the DEFINITIVE LE trial, follow-up assessments occurred up to 1 year postprocedure. Of the 800 patients enrolled, 145 subjects with 189 infrapopliteal lesions met the criteria for this analysis. Seventy (48.3%) and 75 (51.7%) patients were suffering critical limb ischemia (CLI) and intermittent claudication, respectively; 68.3% (99/145) had diabetes. The mean lesion length was 58±44 mm (all lesions); 20.2% were occluded. The primary endpoint for patients with claudication was duplex ultrasound-derived primary patency, while for subjects with CLI it was freedom from major amputation of the target limb at 1 year. Endpoints and adverse events were independently assessed. Procedure success (≤30% residual stenosis) was achieved in 84% of treated lesions. The 1-year primary patency rate was 84% (claudicants 89.6% and CLI patients 78%, p=0.11), and the freedom from major amputation rate was 97.1% (claudicants 100% and CLI 93.8%, p=0.03). In both claudication and CLI patients, significant improvements in Rutherford category and objective measures of walking distance and quality of life were seen at 1 year in comparison to baseline. This study demonstrates that directional atherectomy in infrapopliteal arteries results in promising technical and clinical results at 1 year for claudicant as well as CLI patients. © The Author(s) 2015.

    Improving services in academic environment can be applied by regulating salary payment process for all employees. As a form of control to maintain financial transparency, employees should have information concerning salary payment process. Currently, notification process of committee honorarium will be accepted by the employees in a manual manner. The salary will be received by the employee bank account and to know its details, they should go to the accounting unit to find out further information. Though there are some employees entering the accounting unit, they still find difficulty to obtain information about detailed honor information that they received in their accounts. This can be caused by many data collected and to be managed. Based on this issue, this research will design a prototype of web-based system for accounting unit system in order to provide detailed financial transaction confirmation to employee bank accounts that have been informed through mobile banking system. This prototype will be developed with Waterfall method through testing on final users after it is developed through PHP program with MySQL as DBMS

    Full Text Available During the Engineering Validation and Engineering Design Activities (EVEDA phase (2007-2014 of the International Fusion Materials Irradiation Facility (IFMIF, an advanced engineering design of the High Flux Test Module (HFTM has been developed with the objective to facilitate the controlled irradiation of steel samples in the high flux area directly behind the IFMIF neutron source. The development process addressed included manufacturing techniques, CAD, neutronic, thermal-hydraulic and mechanical analyses complemented by a series of validation activities. Validation included manufacturing of 1:1 parts and mockups, test of prototypes in the FLEX and HELOKA-LP helium loops of KIT for verification of the thermal and mechanical properties, and irradiation of specimen filled capsule prototypes in the BR2 test reactor. The prototyping activities were backed by several R&D studies addressing focused issues like handling of liquid NaK (as filling medium and insertion of Small Specimen Test Technique (SSTT specimens into the irradiation capsules. This paper provides an up-todate design description of the HFTM irradiation device, and reports on the achieved performance criteria related to the requirements. Results of the validation activities are accounted for and the most important issues for further development are identified.

    This study aims to examine the smallest detectable change (SDC) and test-retest reliability of the Center for Epidemiologic Studies Depression Scale (CES-D), General Self-Efficacy Scale (GSES), and 12-item General Health Questionnaire (GHQ-12). We tested 154 young adults at baseline and 2 weeks later. We calculated the intra-class correlation coefficients (ICCs) for test-retest reliability with a two-way random effects model for agreement. We then calculated the standard error of measurement (SEM) for agreement using the ICC formula. The SEM for agreement was used to calculate SDC values at the individual level (SDC ind ) and group level (SDC group ). The study participants included 137 young adults. The ICCs for all self-reported outcome measurement scales exceeded 0.70. The SEM of CES-D was 3.64, leading to an SDC ind of 10.10 points and SDC group of 0.86 points. The SEM of GSES was 1.56, leading to an SDC ind of 4.33 points and SDC group of 0.37 points. The SEM of GHQ-12 with bimodal scoring was 1.47, leading to an SDC ind of 4.06 points and SDC group of 0.35 points. The SEM of GHQ-12 with Likert scoring was 2.44, leading to an SDC ind of 6.76 points and SDC group of 0.58 points. To confirm that the change was not a result of measurement error, a score of self-reported outcome measurement scales would need to change by an amount greater than these SDC values. This has important implications for clinicians and epidemiologists when assessing outcomes. © 2017 John Wiley & Sons, Ltd.

    Purpose: The purpose of this study was to assess the association between positive post-radiation therapy (RT) biopsy results and subsequent clinical outcomes in males with localized prostate cancer. Methods and Materials: Radiation Therapy Oncology Group study 94-08 analyzed 1979 males with prostate cancer, stage T1b-T2b and prostate-specific antigen concentrations of ≤20 ng/dL, to investigate whether 4 months of total androgen suppression (TAS) added to RT improved survival compared to RT alone. Patients randomized to receive TAS received flutamide with luteinizing hormone releasing hormone (LHRH) agonist. According to protocol, patients without evidence of clinical recurrence or initiation of additional endocrine therapy underwent repeat prostate biopsy 2 years after RT completion. Statistical analysis was performed to evaluate the impact of positive post-RT biopsy results on clinical outcomes. Results: A total of 831 patients underwent post-RT biopsy, 398 were treated with RT alone and 433 with RT plus TAS. Patients with positive post-RT biopsy results had higher rates of biochemical failure (hazard ratio [HR] = 1.7; 95% confidence interval [CI] = 1.3-2.1) and distant metastasis (HR = 2.4; 95% CI = 1.3-4.4) and inferior disease-specific survival (HR = 3.8; 95% CI = 1.9-7.5). Positive biopsy results remained predictive of such outcomes after correction for potential confounders such as Gleason score, tumor stage, and TAS administration. Prior TAS therapy did not prevent elevated risk of adverse outcome in the setting of post-RT positive biopsy results. Patients with Gleason score ≥7 with a positive biopsy result additionally had inferior overall survival compared to those with a negative biopsy result (HR = 1.56; 95% CI = 1.04-2.35). Conclusions: Positive post-RT biopsy is associated with increased rates of distant metastases and inferior disease-specific survival in patients treated with definitive RT and was associated with inferior overall

    There is limited data on the pattern of care for locally advanced, clinical (c) IIIB non-small cell lung cancer (NSCLC) in the TNM-7 staging era. The primary aim of this study was to investigate national patterns of care and outcomes in the Netherlands, with a secondary focus on the use of surgery. Data from patients treated for TNM-7 cIIIB NSCLC between 2010 and 2014, was extracted from the Netherlands Cancer Registry (NCR). Survival data was obtained from the automated Civil Registry. 43.762 patients with NSCLC were recorded in the NCR during this 5-year period, with cIIIB accounting for 10% (n=4.401). Clinical N2 (37%) and N3 (63%) nodal involvement was pathologically confirmed in 50.8%. The use of endobronchial ultrasound (EBUS) increased with time from 9% to 29% (pNetherlands, CRT is the most frequent treatment for cIIIB NSCLC in the TNM-7 era. The use of surgery is limited. Accurate staging requires specific attention and the scarce use of radical treatment in elderly patients merits further evaluation. Copyright © 2017 Elsevier B.V. All rights reserved.

    The World Health Organization (WHO) thymoma histological classification clinical value remains a controversy. In this study, we evaluated its prognostic significance in patients with thymoma treated with radical intent. Six high-volume Italian Thoracic Surgery Institutions collaborated with their own retrospective anonymized datasets. Demographic, clinical, pathological and treatment data were examined. A WHO histological classification (WHO-HC) collapsed scheme (A/AB and B1/B2 types merged) was proposed and compared with the traditional one. Predictors of survival were assessed using a Cox model with shared frailty. Competing-risk regression models were performed to identify the association between individual factors and freedom from recurrence. Between 1990 and 2011, 750 thymomas were operated on in participating centres. Myasthenia gravis was observed in 363 (48%) patients. A complete resection was achieved in 676 (91%) cases. One hundred and nine patients (15%) had a WHO-HC A type, 166 (22%) AB, 179 (24%) B1, 158 (21%) B2 and 135 (18%) B3. The rate of 5-year OS and cumulative incidence of recurrence for all cases was 91% and 0.11, respectively. Five-year survival rates by WHO-HC in the collapsed scheme were A/AB 93%, early-B 90% and advanced-B 85%. Masaoka stage only was demonstrated to be an independent predictor for survival and recurrence. The WHO-collapsed scheme showed a trend in influencing recurrence overall survival development (hazard ratio: 1.32; P = 0.16). Our results show evidence of lack of significance by WHO-HC in influencing prognosis, even though the proposed collapsed scheme revealed a fair stratification of risk to relapses and better correlation with patients' clinical characteristics. © The Author 2014.

    Microbial-explicit models of soil carbon (C) and nitrogen (N) cycling have improved upon simulations of C and N stocks and flows at site-to-global scales relative to traditional first-order linear models. However, the response of microbial-explicit soil models to global change factors depends upon which parameters and processes in a model are altered by those factors. We used the MIcrobial-MIneral Carbon Stabilization Model with coupled N cycling (MIMICS-CN) to compare modeled responses to changes in temperature and plant inputs at two previously-modeled sites (Harvard Forest and Kellogg Biological Station). We spun the model up to equilibrium, applied each perturbation, and evaluated 15 years of post-perturbation C and N pools and fluxes. To model the effect of increasing temperatures, we independently examined the impact of decreasing microbial C use efficiency (CUE), increasing the rate of microbial turnover, and increasing Michaelis-Menten kinetic rates of litter decomposition, plus several combinations of the three. For plant inputs, we ran simulations with stepwise increases in metabolic litter, structural litter, whole litter (structural and metabolic), or labile soil C. The cumulative change in soil C or N varied in both sign and magnitude across simulations. For example, increasing kinetic rates of litter decomposition resulted in net releases of both C and N from soil pools, while decreasing CUE produced short-term increases in respiration but long-term accumulation of C in litter pools and shifts in soil C:N as microbial demand for C increased and biomass declined. Given that soil N cycling constrains the response of plant productivity to global change and that soils generate a large amount of uncertainty in current earth system models, microbial-explicit models are a critical opportunity to advance the modeled representation of soils. However, microbial-explicit models must be improved by experiments to isolate the physiological and stoichiometric

    Objectives This paper aims to describe low-income recipients of a community-based diaper bank and the multiple daily challenges they face. Our paper seeks to document the health, social, and financial outcomes recipients experienced after receiving assistance. Methods We surveyed families (n = 150) about their experiences receiving diapers from a diaper bank in the southeastern United States. Additionally, we conducted short, focused interviews with families (n = 15) about outcomes after receiving diapers. Results Families experience regularly a range of challenges meeting basic needs. These difficulties include high unmet needs for transportation, food, and nonfood essentials such as personal hygiene items. Families experiencing the greatest difficulty in paying utility or medical bills were significantly more likely to have a high level of diaper need compared to families facing these challenges less often (AORs ranging from 3.40 to 9.39). As a result of receiving diapers, families reported positive health, social, and economic outcomes. Families reported positive changes in parental mood; improved child health and happiness; increased opportunities for childcare, work, and school attendance; and the ability to divert household finances toward other basic needs, including utilities and medical care. Conclusions for Practice The monetary value of the supplemental provision of diapers is a small investment in affected families' economic, social, and health outcomes. The positive effects continue far longer than the diapers provided. We demonstrate the social value of such an operation, and recommend the expansion of federal, state, and local safety net programs to help low-income families secure a steady supply of diapers.

    The present study tested real-world racial stereotype use in the context of college athletic recruiting. Stereotype confirmation suggests that observers use stereotypes as hypotheses and interpret relevant evidence in a biased way that confirms their stereotypes. Shifting standards suggest that the evaluative standard to which we hold a target changes as a function of their group membership. We examined whether stereotype confirmation and shifting standards effects would be seen in college football coaches during recruiting. College football coaches evaluated a Black or White player on several attributes and made both zero- and non-zero-sum allocations. Results suggested that coaches used the evidence presented to develop biased subjective evaluations of the players based on race while still maintaining equivalent objective evaluations. Coaches also allocated greater overall resources to the Black recruit than the White recruit.

    Measurement of thyroglobulin (Tg) by mass spectrometry (Tg-MS) is emerging as a tool for accurate Tg quantification in patients with anti-Tg autoantibodies (TgAbs). The objective of the study was to perform analytical and clinical evaluations of two Tg-MS assays in comparison with immunometric Tg assays (Tg-IAs) and Tg RIAs (Tg-RIAs) in a cohort of thyroid cancer patients. A total of 589 samples from 495 patients, 243 TgAb-/252 TgAb+, were tested by Beckman, Roche, Siemens-Immulite, and Thermo-Brahms Tg and TgAb assays, two Tg-RIAs, and two Tg-MS assays. The frequency of TgAb+ was 58%, 41%, 27%, and 39% for Roche, Beckman, Siemens-Immulite, and Thermo-Brahms, respectively. In TgAb- samples, clinical sensitivities and specificities of 100% and 74%-100%, respectively, were observed across all assays. In TgAb+ samples, all Tg-IAs demonstrated assay-dependent Tg underestimation, ranging from 41% to 86%. In TgAb+ samples, the use of a common cutoff (0.5 ng/mL) for the Tg-MS, three Tg-IAs, and the USC-RIA improved the sensitivity for the Tg-MSs and Tg-RIAs when compared with the Tg-IAs. In up to 20% of TgAb+ cases, Tg-IAs failed to detect Tg that was detectable by Tg-MS. In Tg-RIAs false-high biases were observed in TgAb+ samples containing low Tg concentrations. Tg-IAs remain the method of choice for Tg quantitation in TgAb- patients. In TgAb+ patients with undetectable Tg by immunometric assay, the Tg-MS will detect Tg in up to 20% additional cases. The Tg-RIA will detect Tg in approximately 35% cases, but a significant proportion of these will be clinical false-positive results. The undetectable Tg-MS seen in approximately 40% of TgAb+ cases in patients with disease need further evaluation.

    The aim of this study was to explore intensive care nursing students experiences with confirming communication skills training in a simulation-based environment. The study has a qualitative, exploratory and descriptive design. The participants were students in a post-graduate program in intensive care nursing, that had attended a one day confirming communication course. Three focus group interviews lasting between 60 and 80min were conducted with 14 participants. The interviews were transcribed verbatim. Thematic analysis was performed, using Braun & Clark's seven steps. The analysis resulted in three main themes: "awareness", "ice-breaker" and "challenging learning environment". The participants felt that it was a challenge to see themselves on the video-recordings afterwards, however receiving feedback resulted in better self-confidence in mastering complex communication. The main finding of the study is that the students reported improved communication skills after the confirming communication course. However; it is uncertain how these skills can be transferred to clinical practice improving patient outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

  10. Confirmation bias in studies of nestmate recognition: a cautionary note for research into the behaviour of animals.

    Directory of Open Access Journals (Sweden)

    Ellen van Wilgenburg

    Full Text Available Confirmation bias is a tendency of people to interpret information in a way that confirms their expectations. A long recognized phenomenon in human psychology, confirmation bias can distort the results of a study and thus reduce its reliability. While confirmation bias can be avoided by conducting studies blind to treatment groups, this practice is not always used. Surprisingly, this is true of research in animal behaviour, and the extent to which confirmation bias influences research outcomes in this field is rarely investigated. Here we conducted a meta-analysis, using studies on nestmate recognition in ants, to compare the outcomes of studies that were conducted blind with those that were not. Nestmate recognition studies typically perform intra- and inter colony aggression assays, with the a priori expectation that there should be little or no aggression among nestmates. Aggressive interactions between ants can include subtle behaviours such as mandible flaring and recoil, which can be hard to quantify, making these types of assays prone to confirmation bias. Our survey revealed that only 29% of our sample of 79 studies were conducted blind. These studies were more likely to report aggression among nestmates if they were conducted blind (73% than if they were not (21%. Moreover, we found that the effect size between nestmate and non-nestmate treatment means is significantly lower in experiments conducted blind than those in which colony identity is known (1.38 versus 2.76. We discuss the implications of the impact of confirmation bias for research that attempts to obtain quantitative synthesises of data from different studies.

    This study sought to determine the medium-term patient-reported and radiographic outcomes in patients undergoing surgery for hallux valgus. A total of 118 patients (162 feet) underwent surgery for hallux valgus between January 2008 and June 2009. The Manchester-Oxford Foot Questionnaire (MOXFQ), a validated tool for the assessment of outcome after surgery for hallux valgus, was used and patient satisfaction was sought. The medical records and radiographs were reviewed retrospectively. At a mean of 5.2 years (4.7 to 6.0) post-operatively, the median combined MOXFQ score was 7.8 (IQR:0 to 32.8). The median domain scores for pain, walking/standing, and social interaction were 10 (IQR: 0 to 45), 0 (IQR: 0 to 32.1) and 6.3 (IQR: 0 to 25) respectively. A total of 119 procedures (73.9%, in 90 patients) were reported as satisfactory but only 53 feet (32.7%, in 43 patients) were completely asymptomatic. The mean (SD) correction of hallux valgus, intermetatarsal, and distal metatarsal articular angles was 18.5° (8.8°), 5.7° (3.3°), and 16.6° (8.8°), respectively. Multivariable regression analysis identified that an American Association of Anesthesiologists grade of >1 (Incident Rate Ratio (IRR) = 1.67, p-value = 0.011) and recurrent deformity (IRR = 1.77, p-value = 0.003) were associated with significantly worse MOXFQ scores. No correlation was found between the severity of deformity, the type, or degree of surgical correction and the outcome. When using a validated outcome score for the assessment of outcome after surgery for hallux valgus, the long-term results are worse than expected when compared with the short- and mid-term outcomes, with 25.9% of patients dissatisfied at a mean follow-up of 5.2 years. ©2015 The British Editorial Society of Bone & Joint Surgery.

    The objective of the present study is to investigate the effects of a worksite health promotion intervention on musculoskeletal symptoms, physical functioning, work ability, work-related vitality, work performance, and sickness absence. In a randomized controlled design, 314 construction workers were randomized into an intervention group (n = 162) receiving personal coaching, tailored information, and materials, and a control group (n = 152) receiving usual care. Sickness absence was recorded continuously in company records, and questionnaires were completed before, directly after the 6-month intervention period, and 12 months after baseline measurements. Linear and logistic regression analyses were performed to determine intervention effects. No significant changes at 6 or 12 months of follow-up were observed in musculoskeletal symptoms, physical functioning, work ability, work-related vitality, work performance, and sickness absence as a result of the intervention. This study shows that the intervention was not statistically significantly effective on secondary outcomes. Although the intervention improved physical activity, dietary, and weight-related outcomes, it was not successful in decreasing musculoskeletal symptoms and improving other work-related measures. Presumably, more multifaceted interventions are required to establish significant change in these outcomes.

    Objective Guided by the theory of planned behaviour (TPB) and health literacy concepts, SIPsmartER is a six-month multicomponent intervention effective at improving SSB behaviours. Using SIPsmartER data, this study explores prediction of SSB behavioural intention (BI) and behaviour from TPB constructs using: (1) cross-sectional and prospective models and (2) 11 single-item assessments from interactive voice response (IVR) technology. Design Quasi-experimental design, including pre- and post-outcome data and repeated-measures process data of 155 intervention participants. Main Outcome Measures Validated multi-item TPB measures, single-item TPB measures, and self-reported SSB behaviours. Hypothesised relationships were investigated using correlation and multiple regression models. Results TPB constructs explained 32% of the variance cross sectionally and 20% prospectively in BI; and explained 13–20% of variance cross sectionally and 6% prospectively. Single-item scale models were significant, yet explained less variance. All IVR models predicting BI (average 21%, range 6–38%) and behaviour (average 30%, range 6–55%) were significant. Conclusion Findings are interpreted in the context of other cross-sectional, prospective and experimental TPB health and dietary studies. Findings advance experimental application of the TPB, including understanding constructs at outcome and process time points and applying theory in all intervention development, implementation and evaluation phases.

    Severe cerebral vasospasm is a major cause of death and disability in patients with aneurysmal subarachnoid hemorrhage. No causative treatment is yet available and hypertensive hypervolemic therapy (HHT) is often insufficient to avoid delayed cerebral ischemia and neurological deficits. We compared patients receiving continuous intra-arterial infusion of the calcium-antagonist nimodipine with a historical group treated with HHT and oral nimodipine alone. Between 0.5 and 1.2 mg/h of nimodipine were continuously administered by intra-arterial infusion via microcatheters either into the internal carotid or vertebral artery or both, depending on the areas of vasospasm. The effect was controlled via multimodal neuromonitoring and transcranial Doppler sonography. Outcome was determined by means of the Glasgow Outcome Scale at discharge and 6 months after the hemorrhage and compared to a historical control group. Twenty-one patients received 28 intra-arterial nimodipine infusions. Six months after discharge, the occurrence of cerebral infarctions was significantly lower (42.6 %) in the nimodipine group than in the control group (75.0 %). This result was reflected by a significantly higher proportion (76.0 %) of patients with good outcome in the nimodipine-treated group, when compared to 10.0 % good outcome in the control group. Median GOS was 4 in the nimodipine group and 2 in the control group (p = 0.001). Continuous intra-arterial nimodipine infusion is an effective treatment for patients with severe cerebral vasospasm who fail to respond to HHT and oral nimodipine alone. Key to the effective administration of continuous intra-arterial nimodipine is multimodal neuromonitoring and the individual adaptation of dosage and time of infusion for each patient.

The influence of the predictors was assessed by relative risks. RESULTS: After 22 years, four out of five patients still experienced low back pain....... The perception of poor working conditions correlates with recurrent low back pain, intake of painkillers and limitations to daily life. CONCLUSION: Compared with pain history and clinical findings, the perception of workload is a better predictor of the long-term outcome of low back pain Udgivelsesdato: 2010/8/3...

    The objective was to examine the effect of Expressive Writing Intervention (EWI) on self-reported physical symptoms and healthcare utilization in a nationwide randomized controlled trial with Danish women treated for primary breast cancer, and to explore participant characteristics related to emotion regulation as possible moderators of the effect. Women who had recently completed treatment for primary breast cancer (n = 507) were randomly assigned to three 20 min. home-based writing exercises, one week apart, focusing on emotional disclosure (EWI) of a distressing experience (their cancer or a non-cancer topic) or a non-disclosing topic (control). Outcomes were self-reported physical symptoms and healthcare utilization (visits and telephone contacts with GP) 3 and 9 months post-intervention. Potential moderators were repressive coping, alexithymia, rumination, social constraints, and writing topic. Results revealed no group by time interaction effects for any outcomes. Moderation analyses showed that 1) low alexithymic women in the EWI group showed larger decreases in GP telephone calls over time than both high alexithymic women and controls and 2) women in the EWI group writing about their own cancer, but not women writing about other topics, showed a larger decrease than controls. The results from this large randomized trial are concordant with previous findings showing that EWI is unlikely to be a generally applicable intervention to improve health-related outcomes in cancer patients and cancer survivors. However, written disclosure might have a beneficial impact for individuals who write about their own cancer, as well as for those low in alexithymia.

    It is controversial whether the surgical restoration of sagittal balance and spinopelvic angulation in a single level lumbar degenerative spondylolisthesis results in clinical improvements. The purpose of this study to systematically review the available literature to determine whether the surgical correction of malalignment in lumbar degenerative spondylolisthesis correlates with improvements in patient-reported clinical outcomes. Literature searches were performed via Ovid Medline, Embase, CENTRAL and Web of Science using search terms "lumbar," "degenerative/spondylolisthesis" and "surgery/surgical/surgeries/fusion". This resulted in 844 articles and after reviewing the abstracts and full-texts, 13 articles were included for summary and final analysis. There were two Level II articles, four Level III articles and five Level IV articles. Most commonly used patient-reported outcome measures (PROMs) were Oswestery disability index (ODI) and visual analogue scale (VAS). Four articles were included for the final statistical analysis. There was no statistically significant difference between the patient groups who achieved successful surgical correction of malalignment and those who did not for either ODI (mean difference -0.94, CI -8.89-7.00) or VAS (mean difference 1.57, CI -3.16-6.30). Two studies assessed the efficacy of manual reduction of lumbar degenerative spondylolisthesis and their clinical outcomes after the operation, and there was no statistically significant improvement. Overall, the restoration of focal lumbar lordosis and restoration of sagittal balance for single-level lumbar degenerative spondylolisthesis does not seem to yield clinical improvements but well-powered studies on this specific topic is lacking in the current literature. Future well-powered studies are needed for a more definitive conclusion. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2012-01-01

    Study design: Systematic review. Study rationale: Chronic sacroiliac joint pain (CSJP) is a common clinical entity with highly controversial treatment options. A recent systematic review compared surgery with denervation, but the current systematic review compares outcomes of surgical intervention with therapeutic injection for the treatment of CSJP and serves as the next step for evaluating current evidence on the comparative effectiveness of treatments for non-traumatic sacroiliac joint pain. Objective or clinical question: In adult patients with injection-confirmed CSJP, does surgical treatment lead to better outcomes and fewer complications than injection therapy? Methods: A systematic review of the English-language literature was undertaken for articles published between 1970 and June 2012. Electronic databases and reference lists of key articles were searched to identify studies evaluating surgery or injection treatment for injection-confirmed CSJP. Studies involving traumatic onset or non-injection–confirmed CSJP were excluded. Two independent reviewers assessed the level of evidence quality using the grading of recommendations assessment, development and evaluation (GRADE) system, and disagreements were resolved by consensus. Results: We identified twelve articles (seven surgical and five injection treatment) meeting our inclusion criteria. Regardless of the type of treatment, most studies reported over 40% improvement in pain as measured by Visual Analog Scale or Numeric rating Scale score. Regardless of the type of treatment, most studies reported over 20% improvement in functionality. Most complications were reported in the surgical studies. Conclusion: Surgical fusion and therapeutic injections can likely provide pain relief, improve quality of life, and improve work status. The comparative effectiveness of these interventions cannot be evaluated with the current literature. PMID:23526911

    Application of auto-SCT in the post-remission therapy for adolescents and young adults (AYAs) with ALL is controversial. We analyzed the outcomes of 79 AYAs (15-24 years) with ALL who received our designed total therapy protocol with auto-SCT in first CR from 1990 to 2009. The estimated OS and EFS at 5 years for the cohort were 62.8±5.9 and 61.5±5.7%. The cumulative non-relapse mortality and relapse rate at 5 years for the cohort were 7.2±3.1 and 33.6±5.8%. Time to CR >4 weeks was the only independent unfavorable factor associated with OS, EFS and relapse in multivariate analysis. Patients in standard risk (SR) group and high risk (HR) group had better OS (78.3±7.4, 63.8±10.2 vs 38.1±11.6%) and EFS (78.0±7.4, 63.4±9.4 vs 32.4±11.3%), and lower relapse rate (15.9±6.5, 31.5±9.5 vs 65.7±11.8%) compared with patients in very high risk (VHR) group. Our data confirmed that auto-SCT-based total therapy might be an optional treatment strategy for AYAs with ALL in SR. Patients in HR also could get benefit from such schedule. But for those in VHR, allogenetic SCT is still the prior recommendation for the frequent recurrence after auto-SCT.

    Objectives: To investigate the presence of Legionella spp in cooling tower water. Legionella proliferation in cooling tower water has serious public health implications as it can be transmitted to humans via aerosols and cause Legionnaires’ disease. Methods: Samples of cooling tower water were collected from King Fahd Hospital of the University (KFHU) (Imam Abdulrahman Bin Faisal University, 2015/2016). The water samples were analyzed by a standard Legionella culture method, real-time polymerase chain reaction (RT-PCR), and 16S rRNA next-generation sequencing. In addition, the bacterial community composition was evaluated. Results: All samples were negative by conventional Legionella culture. In contrast, all water samples yielded positive results by real-time PCR (105 to 106 GU/L). The results of 16S rRNA next generation sequencing showed high similarity and reproducibility among the water samples. The majority of sequences were Alpha-, Beta-, and Gamma-proteobacteria, and Legionella was the predominant genus. The hydrogen-oxidizing gram-negative bacterium Hydrogenophaga was present at high abundance, indicating high metabolic activity. Sphingopyxis, which is known for its resistance to antimicrobials and as a pioneer in biofilm formation, was also detected. Conclusion: Our findings indicate that monitoring of Legionella in cooling tower water would be enhanced by use of both conventional culturing and molecular methods. PMID:29436561

    Full Text Available Background: The extent of tumor may necessitate resection of the complete femur rarely to achieve adequate oncologic clearance in bone sarcomas. We present our experience with reconstruction in such cases using an indigenously manufactured, low-cost, total femoral prosthesis (TFP. We assessed the complications of the procedure, the oncologic and functional outcomes, and implant survival. Materials and Methods: Eight patients (four males and four females with a mean age of 32 years, operated between December 2003 and June 2009, had a TFP implanted. The diagnosis included osteogenic sarcoma (5, Ewing′s sarcoma (1, and chondrosarcoma (2. Mean followup was 33 months (9-72 months for all and 40 months (24-72 months in survivors. They were evaluated by Musculoskeletal Tumor Society score, implant survival as well as patient survival. Results: There was one local recurrence and five of seven patients are currently alive at the time of last followup. The Musculoskeletal Tumor Society score for patients ranged from 21 to 25 with a mean of 24 (80%. The implant survival was 88% at 5 years with only one TFP needing removal because of infection. Conclusions: A TFP in appropriately indicated patients with malignant bone tumors is oncologically safe. A locally manufactured, cost-effective implant provided consistent and predictable results after excision of the total femur with good functional outcomes.

    Objectives. We reviewed changes in blood glucose, blood pressure, and cholesterol levels among American Indians and Alaska Natives between 1995 and 2001 to estimate the quality of diabetes care in the Indian Health Service (IHS) health care delivery system. Methods. We conducted a cross-sectional analysis of data from the Indian Health Service Diabetes Care and Outcomes Audit. Results. Adjusted mean Hemoglobin A1c (HbA1c) levels (7.9% vs 8.9%) and mean diastolic blood pressure levels (76 vs 79 mm Hg) were lower in 2001 than in 1995, respectively. A similar pattern was observed for mean total cholesterol (193 vs 208 mg/dL) and triglyceride (235 vs 257 mg/dL) levels in 2001 and 1995, respectively. Conclusions. We identified changes in intermediate clinical outcomes over the period from 1995 to 2001 that may reflect the global impact of increased resource allocation and improvements in processes on the quality of diabetes care, and we describe the results that may be achieved when community, health program, and congressional initiatives focus on common goals.

    High fractions of inspired oxygen may augment lung damage to exacerbate lung injury in patients with acute respiratory distress syndrome. Participants enrolled in Acute Respiratory Distress Syndrome Network trials had a goal partial pressure of oxygen in arterial blood range of 55-80 mm Hg, yet the effect of oxygen exposure above this arterial oxygen tension range on clinical outcomes is unknown. We sought to determine if oxygen exposure that resulted in a partial pressure of oxygen in arterial blood above goal (> 80 mm Hg) was associated with worse outcomes in patients with acute respiratory distress syndrome. Longitudinal analysis of data collected in these trials. Ten clinical trials conducted at Acute Respiratory Distress Syndrome Network hospitals between 1996 and 2013. Critically ill patients with acute respiratory distress syndrome. None. We defined above goal oxygen exposure as the difference between the fraction of inspired oxygen and 0.5 whenever the fraction of inspired oxygen was above 0.5 and when the partial pressure of oxygen in arterial blood was above 80 mm Hg. We then summed above goal oxygen exposures in the first five days to calculate a cumulative above goal oxygen exposure. We determined the effect of a cumulative 5-day above goal oxygen exposure on mortality prior to discharge home at 90 days. Among 2,994 participants (mean age, 51.3 yr; 54% male) with a study-entry partial pressure of oxygen in arterial blood/fraction of inspired oxygen that met acute respiratory distress syndrome criteria, average cumulative above goal oxygen exposure was 0.24 fraction of inspired oxygen-days (interquartile range, 0-0.38). Participants with above goal oxygen exposure were more likely to die (adjusted interquartile range odds ratio, 1.20; 95% CI, 1.11-1.31) and have lower ventilator-free days (adjusted interquartile range mean difference of -0.83; 95% CI, -1.18 to -0.48) and lower hospital-free days (adjusted interquartile range mean difference of -1.38; 95

    Normal pressure hydrocephalus (NPH) remains most often a clinical diagnosis and has been widely considered responsive to the placement of a cerebrospinal fluid (CSF) shunt. The high incidence of patients with Alzheimer's disease (AD) with NPH symptoms leads to poorer outcomes than would be expected in patients with NPH alone. This article reviews a series of patients operated on for presumed NPH in whom preoperative high-volume lumbar puncture (HVLP) and intraoperative cortical brain biopsies were performed. The data derived from these procedures were then used to understand the incidence of AD in patients presenting with NPH symptoms and to analyze the efficacy of HVLP in patients with NPH and patients with concurrent AD (NPH+AD). A review of the outcomes of shunt surgery is provided. The cases of all patients who underwent placement of a CSF shunt for NPH from 1998 to 2013 at the University of Virginia by the senior author were retrospectively reviewed. Patients who underwent HVLP and patients who underwent cortical brain biopsies were stratified based on the biopsy results into an NPH-only group and an NPH+AD group. The HVLP results and outcomes were then compared in these 2 groups. From 1998 to 2013, 142 patients underwent shunt operations because of a preoperative clinical diagnosis of NPH. Of the patients with a shunt who had a diagnosis of NPH, 105 (74%) received HVLPs. Of 142 shunt-treated patients with NPH, 27 (19%) were determined to have concomitant Alzheimer's pathology based on histopathological findings at the time of shunting. Patients who underwent repeat biopsies had an initial positive outcome. After they clinically deteriorated, they underwent repeat biopsies during shunt interrogation, and 13% of the repeat biopsies demonstrated Alzheimer's pathology. Improvements in gait and cognition did not reach significance between the NPH and NPH+AD groups. In total, 105 patients underwent HVLP before shunt placement. In the NPH cohort, 44.6% of patients

    The CERN Library Information desk.At a meeting on the Wednesday before Easter, the Executive Committee endorsed a policy of open access to all the laboratory's results, as expressed in the document ‘Continuing CERN action on Open Access' (http://cds.cern.ch/record/828991/files/open-2005-006.pdf), released by its Scientific Information Policy Board (SIPB) earlier in the month. "This underlines CERN's commitment to sharing the excitement of fundamental research with as wide an audience as possible", said Guido Altarelli, current SIPB chairman. Open Access to scientific knowledge is today the goal of an increasing component of the worldwide scientific community. It is a concept, made possible by new electronic tools, which would bring enormous benefits to all readers by giving them free access to research results. CERN has implicitly supported such moves from its very beginning. Its Convention (http://cds.cern.ch/record/330625/files/cm-p00046871.pdf), adopted in 1953, requires openness, stipulating that "......

Empagliflozin showed lower rates of death from cardiovascular causes or from any causes and lower hospitalization rates from heart failure compared with placebo, both in addition to standard care. This commentary discusses the existence of a possible class effect considering the available evidence described for other SGLT2 inhibitors. Main text: Empagliflozin, dapagliflozin and canagliflozin share the same mechanism of action, and it is a plausible hypothesis that some of the benefits of empagliflozin treatment could also be expected from other SGLT2 inhibitors. However, the rapid and persistent occurrence of cardiovascular benefits observed with empagliflozin and the different results shown by the three inhibitors in meta-analyses of some of their respective Phase II and III trials might suggest another possible mechanism of action, perhaps related to the different selectivity to inhibit SGLT-2 and other SGLT family members that these compounds present. Conclusion: There is still lack of evidence to answer whether the cardiovascular benefits observed with empagliflozin in the EMPA-REG OUTCOME study could be seen as a “class effect”, which is also attributable to dapagliflozin and canagliflozin.

    In a previous study, we have shown that HLA class II antibodies and a high soluble CD30 (sCD30) measured at least 1 year post-transplant predict subsequent graft failure. We have now updated the results of this same cohort of 208 patients 15 months later. HLA-specific antibodies (class I and class II) were detected by ELISA LAT-M and Luminex LabScreen assays. Data on graft outcome was collected with a median follow-up of 4.7 years. By Kaplan-Meier analysis, class II antibody was again associated with a poorer outcome, with an estimated 6-year graft survival of 67% and 71% when detected by ELISA and Luminex, respectively, compared with 92% for those without class II antibody (p soluble CD30 level of > or = 100 U/ml was also associated with a poorer estimated 6-year graft survival (p = 0.02). HLA antibodies and high sCD30 (> or = 100 U/ml) had an additive effect such that those with both high sCD30 and class II antibodies had a hazard ratio for subsequent graft failure of 18.1 (p = 0.0008) and 8.6 (p = 0.007) when detected by ELISA and Luminex, respectively. These data show that detection of HLA class II antibodies and serum sCD30 measured at least 1 year post-transplant continues to predict a subsequent outcome up to 6 years after the initial measurement; they also show that such measures provide important information that may allow for modification of ongoing therapy.

  11. NASA Observatory Confirms Black Hole Limits

    2005-02-01

    The very largest black holes reach a certain point and then grow no more, according to the best survey to date of black holes made with NASA's Chandra X-ray Observatory. Scientists have also discovered many previously hidden black holes that are well below their weight limit. These new results corroborate recent theoretical work about how black holes and galaxies grow. The biggest black holes, those with at least 100 million times the mass of the Sun, ate voraciously during the early Universe. Nearly all of them ran out of 'food' billions of years ago and went onto a forced starvation diet. Focus on Black Holes in the Chandra Deep Field North Focus on Black Holes in the Chandra Deep Field North On the other hand, black holes between about 10 and 100 million solar masses followed a more controlled eating plan. Because they took smaller portions of their meals of gas and dust, they continue growing today. "Our data show that some supermassive black holes seem to binge, while others prefer to graze", said Amy Barger of the University of Wisconsin in Madison and the University of Hawaii, lead author of the paper describing the results in the latest issue of The Astronomical Journal (Feb 2005). "We now understand better than ever before how supermassive black holes grow." One revelation is that there is a strong connection between the growth of black holes and the birth of stars. Previously, astronomers had done careful studies of the birthrate of stars in galaxies, but didn't know as much about the black holes at their centers. DSS Optical Image of Lockman Hole DSS Optical Image of Lockman Hole "These galaxies lose material into their central black holes at the same time that they make their stars," said Barger. "So whatever mechanism governs star formation in galaxies also governs black hole growth." Astronomers have made an accurate census of both the biggest, active black holes in the distance, and the relatively smaller, calmer ones closer by. Now, for the first

    Purpose: To report the long-term outcomes of bovine ureter grafts as novel conduits for haemodialysis fistulas. Materials and Methods: Thirty-five patients underwent placement of a total of 40 SynerGraft 100 (SG100; CryoLife Europa ® , Guildford, UK) bovine ureter grafts between April 2002 and February 2009. Prospective data were collected on all patients, including active surveillance with blood flow studies and 6-monthly duplex ultrasound studies. Main outcome measures were primary and secondary patency rates. Results: Mean follow-up time was 97 weeks (range 4–270). Thirteen patients died from unrelated causes during the study period; 12 of these patients had a functioning graft at the time of death. Five patients underwent transplantation, and all had a functioning graft at transplantation. Twelve patients had a functioning graft at the end of the study period. One hundred and ten stenoses were detected, and 97 venoplasty procedures were performed. Of the stenoses, 41.8% were located at the venous anastomosis, 12.7% within the graft, 17.3% in the outflow veins, and 28.1% in central veins. No arterial stenoses were detected. Primary patency rates were 53% at 6 months and 14% at 1 year. Secondary patency rates were 81% at 6 months, 75% at 1 year, and 56% at 2 years. Conclusions: Active surveillance and intervention was able to achieve satisfactory long-term secondary patency for these novel conduits compared with those made of PTFE seen in other studies.

    A growing number of studies and reviews have documented the impact of telemedicine on diabetes management. However, no meta-analysis has assessed whether including nutritional counseling as part of a telemedicine program has a significant impact on diabetes outcomes or what kind of nutritional counseling is most effective. Original research articles examining the effect of telemedicine interventions on HbA1c levels in patients with Type 1 or Type 2 diabetes were included in this study. A literature search was performed and 92 studies were retained for analysis. We examined stratified results by differentiating interventions using no nutritional counseling from those that used nutritional counseling. We further compared between nutritional counseling administered via short message systems (SMS) such as email and text messages, and nutritional counseling administered via telephone or videoconference. Telemedicine programs that include a nutritional component show similar effect in diabetes management as those programs that do not. Furthermore, subgroup analysis reveals that nutritional intervention via SMS such as email and text messages is at least as equally effective in reducing HbA1c when compared to personal nutritional counseling with a practitioner over videoconference or telephone. The inclusion of nutritional counseling as part of a telemedicine program does not make a significant difference to diabetes outcomes. Incorporating nutritional counseling into telemedicine programs via SMS is at least as effective as counseling via telephone or videoconference. © The Author(s) 2015.

    Abstract Aims We aimed to assess determinants of anorexia, that is loss of appetite in patients with heart failure (HF) and aimed to further elucidate the association between anorexia, functional capacity, and outcomes in affected patients. Methods and results We assessed anorexia status among 166 patients with HF (25 female, 66 ± 12 years) who participated in the Studies Investigating Co‐morbidities Aggravating HF. Anorexia was assessed by a 6‐point Likert scale (ranging from 0 to 5), wherein values ≥1 indicate anorexia. Functional capacity was assessed as peak oxygen uptake (peak VO2), 6 min walk test, and short physical performance battery test. A total of 57 patients (34%) reported any anorexia, and these patients showed lower values of peak VO2, 6 min walk distance, and short physical performance battery score (all P anorexia. A total of 22 patients (13%) died during a mean follow‐up of 22.5 ± 5.1 months. Kaplan‐Meier curves for cumulative survival showed that those patients with anorexia presented higher mortality (Log‐rank test P = 0.03). Conclusions Inflammation, use of loop diuretics, and cachexia are associated with an increased likelihood of anorexia in patients with HF, and patients with anorexia showed impaired functional capacity and poor outcomes.

    Full Text Available Abstract Background Further investigation of confirmed UTI in children aims to prevent renal scarring and future complications. Methods We conducted a systematic review to determine the most effective approach to the further investigation of confirmed urinary tract infection (UTI in children under five years of age. Results 73 studies were included. Many studies had methodological limitations or were poorly reported. Effectiveness of further investigations: One study found that routine imaging did not lead to a reduction in recurrent UTIs or renal scarring. Diagnostic accuracy: The studies do not support the use of less invasive tests such as ultrasound as an alternative to renal scintigraphy, either to rule out infection of the upper urinary tract (LR- = 0.57, 95%CI: 0.47, 0.68 and thus to exclude patients from further investigation or to detect renal scarring (LR+ = 3.5, 95% CI: 2.5, 4.8. None of the tests investigated can accurately predict the development of renal scarring. The available evidence supports the consideration of contrast-enhanced ultrasound techniques for detecting vesico-ureteric reflux (VUR, as an alternative to micturating cystourethrography (MCUG (LR+ = 14.1, 95% CI: 9.5, 20.8; LR- = 0.20, 95%CI: 0.13, 0.29; these techniques have the advantage of not requiring exposure to ionising radiation. Conclusion There is no evidence to support the clinical effectiveness of routine investigation of children with confirmed UTI. Primary research on the effectiveness, in terms of improved patient outcome, of testing at all stages in the investigation of confirmed urinary tract infection is urgently required.

    Zika virus infection during pregnancy is a known cause of congenital microcephaly and other neurologic morbidities. We present the results of a large-scale prenatal screening program in place at a single-center health care system since March 14, 2016. Our aims were to report the baseline prevalence of travel-associated Zika infection in our pregnant population, determine travel characteristics of women with evidence of Zika infection, and evaluate maternal and neonatal outcomes compared to women without evidence of Zika infection. This is a prospective, observational study of prenatal Zika virus screening in our health care system. We screened all pregnant women for recent travel to a Zika-affected area, and the serum was tested for those considered at risk for infection. We compared maternal demographic and travel characteristics and perinatal outcomes among women with positive and negative Zika virus tests during pregnancy. Comprehensive neurologic evaluation was performed on all infants delivered of women with evidence of possible Zika virus infection during pregnancy. Head circumference percentiles by gestational age were compared for infants delivered of women with positive and negative Zika virus test results. From March 14 through Oct. 1, 2016, a total of 14,161 pregnant women were screened for travel to a Zika-affected country. A total of 610 (4.3%) women reported travel, and test results were available in 547. Of these, evidence of possible Zika virus infection was found in 29 (5.3%). In our population, the prevalence of asymptomatic or symptomatic Zika virus infection among pregnant women was 2/1000. Women with evidence of Zika virus infection were more likely to have traveled from Central or South America (97% vs 12%, P Zika virus infection. Additionally, there was no difference in mean head circumference of infants born to women with positive vs negative Zika virus testing. No microcephalic infants born to women with Zika infection were identified

    Researchers and clinicians are increasingly recognizing the value of patient-reported outcome (PRO) data to better characterize people's health and experiences with illness and care. Considering the rising prevalence of cancer in adults aged 65 and older, PRO data are particularly relevant for older adults with cancer, who often require complex cancer care and have additional comorbid conditions. A data linkage between the Surveillance Epidemiology and End Results (SEER) cancer registry and the Medicare Health Outcomes Survey (MHOS) was created through a partnership between the National Cancer Institute and the Centers for Medicare and Medicaid Services that created the opportunity to examine PROs in Medicare Advantage enrollees with and without cancer. The December 2013 linkage of SEER-MHOS data included the linked data for 12 cohorts, bringing the number of individuals in the linked data set to 95,723 with cancer and 1,510,127 without. This article reviews the features of the resource and provides information on some descriptive characteristics of the individuals in the data set (health-related quality of life, body mass index, fall risk management, number of unhealthy days in the past month). Individuals without (n=258,108) and with (n=3,440) cancer (1,311 men with prostate cancer, 982 women with breast cancer, 689 with colorectal cancer, 458 with lung cancer) were included in the current descriptive analysis. Given increasing longevity, advances in effective therapies and earlier detection, and population growth, the number of individuals aged 65 and older with cancer is expected to reach more than 12 million by 2020. SEER-MHOS provides population-level, self-reported, cancer registry-linked data for person-centered surveillance research on this growing population. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Full Text Available The goal of this experimental project was to investigate lay peoples’ perceptions of epistemic authority (EA in the field of finance. EA is defined as the extent to which a source of information is treated as evidence for judgments independently of its objective expertise and based on subjective beliefs. Previous research suggested that EA evaluations are biased and that lay people tend to ascribe higher EA to experts who advise action (in the case of medical experts or confirm clients’ expectations (in the case of politicians. However, there has been no research into biases in lay evaluations of financial experts and this project is aimed to fill this gap. Experiment 1 showed that lay people tended to ascribe greater authority to financial consultants who gave more active advice to clients considering taking out a mortgage. Experiment 2 confirmed the action advice effect found in Experiment 1. However, the outcomes of Experiments 2 and – particularly – 3 suggested that this bias might also be due to clients’ desire to confirm their own opinions. Experiment 2 showed that the action advice effect was moderated by clients’ own opinions on taking loans. Lay people ascribed the greatest EA to the advisor in the scenario in which he advised taking action and where this coincided with the client’s positive opinion on the advisability of taking out a loan. In Experiment 3 only participants with a positive opinion on the financial product ascribed greater authority to experts who recommended it; participants whose opinion was negative tended to rate consultants who advised rejecting the product more highly. To conclude, these three experiments revealed that lay people ascribe higher EA to financial consultants who advise action rather than maintenance of the status quo, but this effect is limited by confirmation bias: when the client’s a priori opinion is salient, greater authority is ascribed to experts whose advice confirms it.

    The goal of this experimental project was to investigate lay peoples' perceptions of epistemic authority (EA) in the field of finance. EA is defined as the extent to which a source of information is treated as evidence for judgments independently of its objective expertise and based on subjective beliefs. Previous research suggested that EA evaluations are biased and that lay people tend to ascribe higher EA to experts who advise action (in the case of medical experts) or confirm clients' expectations (in the case of politicians). However, there has been no research into biases in lay evaluations of financial experts and this project is aimed to fill this gap. Experiment 1 showed that lay people tended to ascribe greater authority to financial consultants who gave more active advice to clients considering taking out a mortgage. Experiment 2 confirmed the action advice effect found in Experiment 1. However, the outcomes of Experiments 2 and - particularly - 3 suggested that this bias might also be due to clients' desire to confirm their own opinions. Experiment 2 showed that the action advice effect was moderated by clients' own opinions on taking loans. Lay people ascribed the greatest EA to the advisor in the scenario in which he advised taking action and where this coincided with the client's positive opinion on the advisability of taking out a loan. In Experiment 3 only participants with a positive opinion on the financial product ascribed greater authority to experts who recommended it; participants whose opinion was negative tended to rate consultants who advised rejecting the product more highly. To conclude, these three experiments revealed that lay people ascribe higher EA to financial consultants who advise action rather than maintenance of the status quo , but this effect is limited by confirmation bias: when the client's a priori opinion is salient, greater authority is ascribed to experts whose advice confirms it. In this sense, results presented in the

    To evaluate fetal ultrasound and magnetic resonance imaging findings among a series of pregnant women with confirmed Zika virus infection to evaluate the signs of congenital Zika syndrome with respect to timing of infection. We conducted a retrospective case series of pregnant women referred to two perinatal clinics in Barranquilla and Ibagué, Colombia, who had findings consistent with congenital Zika syndrome and Zika virus infection confirmed in maternal, fetal, or neonatal samples. Serial ultrasound measurements, fetal magnetic resonance imaging results, laboratory results, and perinatal outcomes were evaluated. We describe 17 cases of confirmed prenatal maternal Zika virus infection with adverse fetal outcomes. Among the 14 symptomatic women, the median gestational age for maternal Zika virus symptoms was 10 weeks (range 7-14 weeks of gestation). The median time between Zika virus symptom onset and microcephaly (head circumference less than 3 standard deviations below the mean) was 18 weeks (range 15-24 weeks). The earliest fetal head circumference measurement consistent with microcephaly diagnosis was at 24 weeks of gestation. The earliest sign of congenital Zika syndrome was talipes equinovarus, which in two patients was noted first at 19 weeks of gestation. Common findings on fetal magnetic resonance imaging were microcephaly, ventriculomegaly, polymicrogyria, and calcifications. Our analysis suggests a period of at least 15 weeks between maternal Zika virus infection in pregnancy and development of microcephaly and highlights the importance of serial and detailed neuroimaging.

    To evaluate the frequency of diagnostic errors assessed by autopsies. Retrospective review of medical and pathological records in an 11-bed closed medical intensive care unit (ICU) at a 860-bed general hospital. Patients who died in the ICU between January 1998 and December 1999. Medical diagnoses were rated into three levels of clinical diagnostic certainty: complete certainty (group L1), minor diagnostic uncertainty (group L2), and major diagnostic uncertainty (group L3). The patients were divided into three error groups: group A, the autopsy confirmed the clinical diagnosis; group B, the autopsy demonstrated a new relevant diagnosis which would probably not have influenced the therapy and outcome; group C, the autopsy demonstrated a new relevant diagnosis which would probably have changed the therapy and outcome. The overall mortality was 20.3% (270/1331 patients). Autopsies were performed in 126 patients (46.9% of deaths), more often in younger patients (66.6+/-13.9 years vs 72.7+/-12.0 years, p<0.001), in patients with shorter ICU stay (4.7+/-5.6 days vs 6.7+/-8.7 days, p=0.054), and in patients in group L3 without chronic diseases (15/126 vs 1/144, p<0.001). Fatal but potentially treatable errors [group C, 12 patients (9.5%)] were found in 8.7%, 10.0%, and 10.5% of patients in groups L1, L2, and L3, respectively (NS between groups). An ICU length of stay shorter than 24 h was not related to the frequency of group C errors. Autopsies are performed more often in younger patients without chronic disease and in patients with a low clinical diagnostic certainty. No level of clinical diagnostic certainty could predict the pathological findings.

    Purpose: To report the final cosmetic results from a single-arm prospective clinical trial evaluating accelerated partial breast irradiation (APBI) using intensity modulated radiation therapy (IMRT) with active-breathing control (ABC). Methods and Materials: Women older than 40 with breast cancer stages 0-I who received breast-conserving surgery were enrolled in an institutional review board-approved prospective study evaluating APBI using IMRT administered with deep inspiration breath-hold. Patients received 38.5 Gy in 3.85-Gy fractions given twice daily over 5 consecutive days. The planning target volume was defined as the lumpectomy cavity with a 1.5-cm margin. Cosmesis was scored on a 4-category scale by the treating physician. Toxicity was scored according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE version 3.0). We report the cosmetic and toxicity results at a median follow-up of 5 years. Results: A total of 34 patients were enrolled. Two patients were excluded because of fair baseline cosmesis. The trial was terminated early because fair/poor cosmesis developed in 7 of 32 women at a median follow-up of 2.5 years. At a median follow-up of 5 years, further decline in the cosmetic outcome was observed in 5 women. Cosmesis at the time of last assessment was 43.3% excellent, 30% good, 20% fair, and 6.7% poor. Fibrosis according to CTCAE at last assessment was 3.3% grade 2 toxicity and 0% grade 3 toxicity. There was no correlation of CTCAE grade 2 or greater fibrosis with cosmesis. The 5-year rate of local control was 97% for all 34 patients initially enrolled. Conclusions: In this prospective trial with 5-year median follow-up, we observed an excellent rate of tumor control using IMRT-planned APBI. Cosmetic outcomes, however, continued to decline, with 26.7% of women having a fair to poor cosmetic result. These results underscore the need for continued cosmetic assessment for patients treated with APBI by technique

    The purpose of this study was to describe the impact of gastrointestinal events on patient-reported outcomes and health care resource use among Asia-Pacific women with postmenopausal osteoporosis. The results of this study show that gastrointestinal events decreased adherence, treatment satisfaction, and quality of life in Asia-Pacific women with postmenopausal osteoporosis. This study aimed to describe the impact of gastrointestinal (GI) events on patient-reported outcomes and health care resource use among Asia-Pacific women with postmenopausal osteoporosis. The MUSIC OS-AP study included an observational cohort study of postmenopausal women with osteoporosis. Women were classified as untreated or treated, with treated patients further classified as new or experienced users. Adherence was measured by the Adherence Evaluation of Osteoporosis treatment (ADEOS) questionnaire, treatment satisfaction by the Osteoporosis Patient Satisfaction Questionnaire (OPSAT) while general health-related and osteoporosis-specific quality of life were measured by the European Quality of Life-5 Dimensions (EQ-5D) questionnaire and the Osteoporosis Assessment Questionnaire (OPAQ), respectively. The association of GI events with these outcomes was determined by covariate-adjusted regression analysis of least squares mean differences in the scores of treated patients with and without GI events. Resource utilization was measured as the number of physician visits over the past 3 months, and multivariate regression analysis was used to assess the association of GI events with the likelihood of a visit. The GI event profile, quality of life scores, and resource use were numerically similar in untreated and treated women. The rate of adherence among treated women was higher in experienced than in new users. As indicated by mean scores, experienced users had better quality of life and slightly higher treatment satisfaction and fewer physician visits than new users. Except for adherence in

    Purpose To study the relationship between functional independence and time to reperfusion in the Solitaire with the Intention for Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke (SWIFT PRIME) trial in patients with disabling acute ischemic stroke who underwent endovascular therapy plus intravenous tissue plasminogen activator (tPA) administration versus tPA administration alone and to investigate variables that affect time spent during discrete steps. Materials and Methods Data were analyzed from the SWIFT PRIME trial, a global, multicenter, prospective study in which outcomes were compared in patients treated with intravenous tPA alone or in combination with the Solitaire device (Covidien, Irvine, Calif). Between December 2012 and November 2014, 196 patients were enrolled. The relation between time from (a) symptom onset to reperfusion and (b) imaging to reperfusion and clinical outcome was analyzed, along with patient and health system characteristics that affect discrete steps in patient workflow. Multivariable logistic regression was used to assess relationships between time and outcome; negative binomial regression was used to evaluate effects on workflow. The institutional review board at each site approved the trial. Patients provided written informed consent, or, at select sites, there was an exception from having to acquire explicit informed consent in emergency circumstances. Results In the stent retriever arm of the study, symptom onset to reperfusion time of 150 minutes led to 91% estimated probability of functional independence, which decreased by 10% over the next hour and by 20% with every subsequent hour of delay. Time from arrival at the emergency department to arterial access was 90 minutes (interquartile range, 69-120 minutes), and time to reperfusion was 129 minutes (interquartile range, 108-169 minutes). Patients who initially arrived at a referring facility had longer symptom onset to groin puncture times compared with

    Little is known about the impact of diabetes self-management behavior (SMB) on long-term outcomes. We aimed to examine the association among patient-reported SMB, intermediate clinical outcomes, and mortality in patients with type 2 diabetes. Data were collected from 340 patients with type 2 diabetes of the KORA-A study (1997/1998) who were recruited from two previous population-based surveys (n = 161) and a myocardial infarction registry (n = 179) in southern Germany. Based on previous methodological work, a high level of SMB was defined as being compliant with at least four of six different self-care dimensions, comprising physical exercise, foot care, blood glucose self-monitoring, weight monitoring, having a diet plan, and keeping a diabetes diary. The vital status of the participants was observed until 2009. Multivariable linear, logistic, and Cox regression models were applied to assess the association with intermediate clinical outcomes at baseline and to predict mortality over the follow-up period, adjusted for sociodemographic, behavioral, and disease-related factors. In the cross-sectional perspective, a high level of SMB was weakly associated with a lower glycated hemoglobin A1c level (-0.44% [-4.8 mmol/mol] [95% CI -0.88 to 0.00]), but not with low-density lipoprotein cholesterol, systolic blood pressure, or the presence of microalbuminuria, peripheral arterial disease, or polyneuropathy. During a mean follow-up time of 11.6 years, 189 patients died. SMB was a preventive factor for all-cause (hazard ratio 0.61 [95% CI 0.40-0.91]) and cardiovascular mortality (0.65 [95% CI 0.41-1.03]). Although measuring SMB is difficult and the used operationalization might be limited, our results give some indication that a high level of SMB is associated with prolonged life expectancy in patients with type 2 diabetes and highlight the potential impact of the patients' active contribution on the long-term trajectory of the disease. We assume that the used proxy for SMB

    Excellent results have recently been reported for both total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA), but there have been few reports about which has a better long-term outcome. The preoperative and postoperative results of TKA and UKA for osteoarthritis of the knee were thus compared. The results of 48 patients who underwent TKA and 25 patients who underwent UKA were evaluated based on clinical scores and survivorship in the middle long-term period. Preoperative, latest postoperative, and changes in the femoro-tibial angle (FTA), range of motion (ROM), Japanese Orthopedic Association score (JOA score), and Japanese Knee Osteoarthritis Measure (JKOM) were compared. The patients' mean age was 73 years. The mean follow-up period was 9 years (TKA: mean, 10.5 years; range, 7-12 years; UKA: mean, 9 years; range, 6-11 years). Preoperative FTA and ROM were significantly higher in the UKA group than in the TKA group. Total changes in all scores were similar among the two groups, as were changes in scores for all JOA and JKOM domains. The cumulative revision rate was higher for UKA than for TKA (7 versus 4%). Kaplan-Meier survivorship at 10 years was 84% for UKA and 92% for TKA. This clinical study found no significant differences between TKA and UKA, except in long-term survivorship.

    This article investigates two kinds of information search strategies in the context of selecting romantic partners. Confirmatory searching occurs when people ask for more information about a romantic partner in order to validate or confirm their assessment. Balanced searches are characterized by a search for risk information for partners rated as attractive and for attractiveness information about partners rated as risky in order to attain a more complete evaluation. A factorial survey computer program randomly constructed five types of partner descriptions and college-age respondents evaluated nine descriptions in terms of both health risk and romantic attractiveness outcomes. The results show little evidence of balanced search strategies: for all vignette types the respondents searched for attractiveness information. Regression analysis of the search outcomes showed no difference between males and females in the desire for attractiveness or risk information, the amount of additional information desired, or the proportion of descriptions for which more information was desired. However, an attractive physical appearance did increase the amount of additional information desired and the proportion of vignettes for which more information was desired. The results were generally inconsistent with a balanced search hypothesis; a better characterization of the respondents' strategy might be "confirmatory bias."

    The aim of the study was to examine dietary patterns and risk of adverse pregnancy outcomes among mothers with inflammatory bowel disease (IBD) in the Norwegian Mother and Child Cohort Study (MoBa). MoBa enrolled participants from all over Norway between 1999 and 2008, and the study comprised 83,988 mothers, of whom there were 183 mothers with Crohn's disease (CD) and 240 with ulcerative colitis (UC). An additional questionnaire was submitted to mothers with IBD in 2013. We extracted three exploratory dietary patterns: a "Prudent," a "Western," and a "Traditional" pattern. We explored the relationship between dietary patterns and IBD and dietary patterns and adverse pregnancy outcomes: small for gestational age (SGA) and preterm delivery (PTD). IBD mothers had a significantly lower adherence to the Traditional dietary pattern [mean score -0.10 (95% CI: - 0.2 - - 0.01)] than non-IBD mothers. In IBD mothers, middle and high adherence to the Traditional dietary pattern was associated with lower risk of SGA [OR tertile 2 vs. tertile 1: 0.44 (95% CI: 0.20 - 0.97) and OR tertile 3 vs. tertile 1: 0.23 (95% CI: 0.08-0.61)] than in IBD and non-IBD mothers with low adherence. In the IBD-subset analyses, similar results were demonstrated for UC mothers [OR tertile 2 vs. tertile 1: 0.21 (95% CI: 0.05 - 0.80) and OR tertile 3 vs. tertile 1: 0.16 (95% CI: 0.04 - 0.60)]. In IBD mothers, higher adherence to a Traditional dietary pattern, characterized by high consumption of lean fish, fish products, potatoes, rice porridge, cooked vegetables, and gravy, was associated with lower risk of SGA. © 2017 Crohn’s & Colitis Foundation of America.

    Purpose: To correlate tumor oxygenation status with long-term biochemical outcome after prostate brachytherapy. Methods and Materials: Custom-made Eppendorf PO{sub 2} microelectrodes were used to obtain PO{sub 2} measurements from the prostate (P), focused on positive biopsy locations, and normal muscle tissue (M), as a control. A total of 11,516 measurements were obtained in 57 men with localized prostate cancer immediately before prostate brachytherapy was given. The Eppendorf histograms provided the median PO{sub 2}, mean PO{sub 2}, and % <5 mm Hg or <10 mm Hg. Biochemical failure (BF) was defined using both the former American Society of Therapeutic Radiation Oncology (ASTRO) (three consecutive raises) and the current Phoenix (prostate-specific antigen nadir + 2 ng/mL) definitions. A Cox proportional hazards regression model evaluated the influence of hypoxia using the P/M mean PO{sub 2} ratio on BF. Results: With a median follow-up time of 8 years, 12 men had ASTRO BF and 8 had Phoenix BF. On multivariate analysis, P/M PO{sub 2} ratio <0.10 emerged as the only significant predictor of ASTRO BF (p = 0.043). Hormonal therapy (p = 0.015) and P/M PO{sub 2} ratio <0.10 (p = 0.046) emerged as the only independent predictors of the Phoenix BF. Kaplan-Meier freedom from BF for P/M ratio <0.10 vs. {>=}0.10 at 8 years for ASTRO BF was 46% vs. 78% (p = 0.03) and for the Phoenix BF was 66% vs. 83% (p = 0.02). Conclusions: Hypoxia in prostate cancer (low mean P/M PO{sub 2} ratio) significantly predicts for poor long-term biochemical outcome, suggesting that novel hypoxic strategies should be investigated.

    Full Text Available Abstract Background Work-related stress is highly prevalent in the educational sector. The aim of the current study was to evaluate the effectiveness of an organizational level, participatory intervention on need for recovery and vitality in educational workers. It was hypothesized that the intervention would decrease need for recovery and increase vitality. Methods A quasi-experiment was conducted at two secondary Vocational Education and Training schools (N = 356 with 12- and 24-months follow-up measurements. The intervention consisted of 1 a needs assessment phase, wherein staff and teachers developed actions for happy and healthy working under supervision of a facilitator, and 2 an implementation phase, wherein these actions were implemented by the management teams. Mixed model analysis was applied in order to assess the differences between the intervention and control group on average over time. All analyses were corrected for baseline values and several covariates. Results No effects of the intervention were found on need for recovery, vitality and most of the secondary outcomes. Two small, statistically significant effects were in unfavorable direction: the intervention group scored on average over time significantly lower on absorption (i.e. a subscale of work engagement and organizational efficacy than the control group. Conclusions Since no beneficial effects of this intervention were found on the primary and most of the secondary outcomes, further implementation of the intervention in its current form is not eligible. We recommend that future organizational level interventions for occupational health 1 incorporate an elaborate implementation strategy, 2 are more specific in relating actions to stressors in the context, and 3 are integrated with secondary preventive, individual focused stress management interventions.

    While behavior change can improve risk factor profiles and prognosis after an acute cardiac event, patients need assistance to achieve sustained lifestyle changes. We developed the "Beating Heart Problems" cognitive-behavioral therapy and motivational interviewing program to support patients to develop behavioral and cognitive self-management skills. We report the results of a randomized controlled trial of the program. Patients (n = 275) consecutively admitted to 2 Melbourne hospitals after acute myocardial infarction (32%), coronary artery bypass graft surgery (40%), or percutaneous coronary intervention (28%) were randomized to treatment (T; n = 139) or control (C; n = 136). T group patients were invited to participate in the 8-week group-based program. Patients underwent risk factor screening 6 weeks after hospital discharge (before randomization) and again 4 and 12 months later. At both the followups, T and C groups were compared on 2-year risk of a recurrent cardiac event and key behavioral outcomes, using both intention-to-treat and "completers only" analyses. Patients ranged in age from 32 to 75 years (mean = 59.0 years; SD - 9.1 years). Most patients (86%) were men. Compared with the C group patients, T group patients tended toward greater reduction in 2-year risk, at both the 4- and 12-month followups. Significant benefits in dietary fat intake and functional capacity were also evident. The "Beating Heart Problems" program showed modest but important benefit over usual care at 4 and, to a lesser extent, 12 months. Modifications to the program such as the inclusion of booster sessions and translation to online delivery are likely to improve outcomes.

    Abstract Aims We previously reported that in the EMPA-REG OUTCOME® trial, empagliflozin added to standard of care reduced the risk of 3-point major adverse cardiovascular events, cardiovascular and all-cause death, and hospitalization for heart failure in patients with type 2 diabetes and high cardiovascular risk. We have now further investigated heart failure outcomes in all patients and in subgroups, including patients with or without baseline heart failure. Methods and results Patients were randomized to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo. Seven thousand and twenty patients were treated; 706 (10.1%) had heart failure at baseline. Heart failure hospitalization or cardiovascular death occurred in a significantly lower percentage of patients treated with empagliflozin [265/4687 patients (5.7%)] than with placebo [198/2333 patients (8.5%)] [hazard ratio, HR: 0.66 (95% confidence interval: 0.55–0.79); P heart failure hospitalization or cardiovascular death of 35 over 3 years. Consistent effects of empagliflozin were observed across subgroups defined by baseline characteristics, including patients with vs. without heart failure, and across categories of medications to treat diabetes and/or heart failure. Empagliflozin improved other heart failure outcomes, including hospitalization for or death from heart failure [2.8 vs. 4.5%; HR: 0.61 (0.47–0.79); P heart failure at baseline in both treatment groups, but were no more common with empagliflozin than with placebo. Conclusion In patients with type 2 diabetes and high cardiovascular risk, empagliflozin reduced heart failure hospitalization and cardiovascular death, with a consistent benefit in patients with and without baseline heart failure.

    The purpose of this study was to evaluate patient satisfaction and clinical outcomes among subjects with mandibular overdentures supported by one or two immediately placed dental implants 5 years after loading. Thirty-six subjects (16 men and 20 women) received one or two dental implants in the anterior mandible, and all implants were loaded the day of surgery. Subjects were scheduled for follow-up 3-, 6-, and 12 months after implant placement and thereafter annually for 4 more years. Patient satisfaction scores were measured with the Oral Health Impact Profile-EDENT (OHIPEDENT) questionnaire. Seventeen subjects (7 male and 10 female) with a mean age of 59.4 years (range, 44 to 74 years) were available for the 5-year follow-up examination. Nine subjects with 10 failing implants were excluded during the first year and nine subjects were lost to follow-up. No implants failed between the 12- and 60-month follow-up examinations, and the need for denture maintenance was low. Mean peri-implant bone change was 0.92 mm, and the Spearman test failed to show correlation between the insertion torque value and implant stability quotient. Patient satisfaction scores increased significantly when compared with baseline values and continued to be high for both groups, with no significant differences. Ten implants in nine subjects failed early, but no failures were observed after the 12-month examination. No significant differences were found between subjects in the two groups with respect to implant survival rates and peri-implant bone loss, and patient satisfaction scores continued to be high. Although patient satisfaction and implant success were high during the 12- to 60-month period, the results should be interpreted with caution because of the high number of failing implants and patients lost to follow-up. More research is needed to study outcomes of treatment with immediately loaded mandibular implant overdentures.

    The present study aimed to investigate the difference in major adverse cardiac events (MACE) at 3 years after double-kissing (DK) crush versus culotte stenting for unprotected left main distal bifurcation lesions (LMDBLs). The multicenter and randomized DKCRUSH-III (Comparison of double kissing crush versus culotte stenting for unprotected distal left main bifurcation lesions: results from a multicenter, randomized, prospective study) showed that DK crush stenting was associated with fewer MACE at 1-year follow-up in patients with LMDBLs compared with culotte stenting. Here, we report the 3-year clinical outcome of the DKCRUSH-III study. A total of 419 patients with LMDBLs who were randomly assigned to either the DK crush or culotte group in the DKCRUSH-III study were followed for 3 year. The primary endpoint was the occurrence of a MACE at 3 years. Stent thrombosis (ST) was the safety endpoint. Patients were classified by simple and complex LMDBLs according to the DEFINITION (Definition and Impact of Complex Bifurcation Lesions on Clinical Outcomes After Percutaneous Coronary Intervention Using Drug-Eluting Stents) study criteria. At 3 years, MACE occurred in 49 patients the culotte group and in 17 patients in the DK crush group (cumulative event rates of 23.7% and 8.2%, respectively; p DK crush group (p = 0.007). Complex LMDBLs were associated with a higher rate of MACE (35.3%) at 3 years compared with a rate of 8.1% in patients with simple LMDBLs (p DK] Crush Versus Culotte Stenting for the Treatment of Unprotected Distal Left Main Bifurcation Lesions: DKCRUSH-III, a Multicenter Randomized Study Comparing Double-Stent Techniques; ChiCTR-TRC-11001877).

    Urinary hormonal markers may assist in increasing the efficacy of Fertility Awareness Based Methods (FABM). This study uses urinary pregnanediol-3a-glucuronide (PDG) testing to more accurately identify the infertile phase of the menstrual cycle in the setting of FABM. Secondary analysis of an observational and simulation study, multicentre, European study. The study includes 107 women and tracks daily first morning urine (FMU), observed the changes in cervical mucus discharge, and ultrasonography to identify the day of ovulation over 326 menstrual cycles. The following three scenarios were tested: (A) use of the daily pregnandiol-3a-glucuronide (PDG) test alone; (B) use of the PDG test after the first positive urine luteinizing hormone (LH) kit result; (C) use of the PDG test after the disappearance of fertile type mucus. Two models were used: (1) one day of PDG positivity; or (2) waiting for three days of PDG positivity before declaring infertility. After the first positivity of a LH test or the end of fertile mucus, three consecutive days of PDG testing over a threshold of 5μg/mL resulted in a 100% specificity for ovulation confirmation. They were respectively associated an identification of an average of 6.1 and 7.6 recognized infertile days. The results demonstrate a clinical scenario with 100% specificity for ovulation confirmation and provide the theoretical background for a future development of a competitive lateral flow assay for the detection of PDG in the urine.

    The purpose of this investigation was to compare the effects of schedule of practice (i.e., blocked vs. random) on outcomes of Sound Production Treatment (SPT; Wambaugh, Kalinyak-Fliszar, West, & Doyle, 1998) for speakers with chronic acquired apraxia of speech and aphasia. A combination of group and single-case experimental designs was used. Twenty participants each received SPT administered with randomized stimuli presentation (SPT-R) and SPT applied with blocked stimuli presentation (SPT-B). Treatment effects were examined with respect to accuracy of articulation as measured in treated and untreated experimental words produced during probes. All participants demonstrated improved articulation of treated items with both practice schedules. Effect sizes were calculated to estimate magnitude of change for treated and untreated items by treatment condition. No significant differences were found for SPT-R and SPT-B relative to effect size. Percent change over the highest baseline performance was also calculated to provide a clinically relevant indication of improvement. Change scores associated with SPT-R were significantly higher than those for SPT-B for treated items but not untreated items. SPT can result in improved articulation regardless of schedule of practice. However, SPT-R may result in greater gains for treated items. https://doi.org/10.23641/asha.5116831.

    The representativeness of the data is one of the main issues in evaluating the significance of research findings. Dropping out is common in adolescent mental health research, and may distort the results. Nevertheless, very little is known about the types of systematic bias that may affect studies in a) the informed consent phase and b) later in follow-up phases. The authors addressed this gap in knowledge in a five-year follow-up study on a sample of adolescents aged 13-18 years. The data were collected using self-report questionnaires. The baseline sample consisted of 4171 adolescents, 1827 (43.8%) of whom gave consent to be contacted for a follow-up survey, but only 797 (19.1%) participated in the follow-up. Binary logistic regression models were used to explain the participation. Young age, female gender, a high number of hobbies, good performance at school in the native language and general subjects, family disintegration such as divorce, high parental employment, and symptoms of depression and anxiety were associated with both consent and participation. However, the effect of mental health aspects was smaller than the effect of age and gender. This study confirmed the possibility of systematic selection bias by adolescents' sociodemographic characteristics. The representativeness of the study sample might have been improved by more intense recruitment strategies. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier Ltd.

    The approach, recommended by GE-ARSD, for confirming the achievement of LMFBR reliability goals relies upon a comprehensive understanding of the physical and operational characteristics of the system and the environments to which the system will be subjected during its operational life. This kind of understanding is required for an approach based on system hardware testing or analyses, as recommended in this report. However, for a system as complex and expensive as the LMFBR, an approach which relies primarily on system hardware testing would be prohibitive both in cost and time to obtain the required system reliability test information. By using an analytical approach, results of tests (reliability and functional) at a low level within the specific system of interest, as well as results from other similar systems can be used to form the data base for confirming the achievement of the system reliability goals. This data, along with information relating to the design characteristics and operating environments of the specific system, will be used in the assessment of the system's reliability

    Full Text Available Aim: To report the prevalence and outcomes of pressure ulcers (PU seen in a cohort of cancer patients requiring home-based palliative care. Materials and Methods: All patients referred for home care were eligible for this prospective observational study, provided they were living within a distance of 35 km from the institute and gave informed consent. During each visit, caregivers were trained and educated for providing nursing care for the patient. Dressing material for PU care was provided to all patients free of cost and care methods were demonstrated. Factors influencing the occurrence and healing of PUs were analyzed using logistic regression. Duration for healing of PU was calculated using the Kaplan Meier method. P < 0.05 are taken as significant. Results: Twenty-one of 108 (19.4% enrolled patients had PU at the start of homecare services. None of the patients developed new PU during the course of home care. Complete healing of PU was seen in 9 (42.9% patients. The median duration for healing of PU was found to be 56 days. Median expenditure incurred in patients with PU was Rs. 2323.40 with a median daily expenditure of Rs. 77.56. Conclusions: The present model of homecare service delivery was found to be effective in the prevention and management of PUs. The high prevalence of PU in this cohort indicates a need for greater awareness for this complication. Clinical Trial Registry Number: CTRI/2014/03/004477

    Blood product usage is a quality outcome for patients undergoing cardiac surgery. To address an increase in blood product usage since the discontinuation of aprotinin, blood conservation strategies were initiated at a tertiary hospital in Oakland, CA. Improving transfusion rates for open heart surgery patients requiring Cardiopulmonary bypass (CPB) involved multiple departments in coordination. Specific changes to conserve blood product usage included advanced CPB technology upgrades, and precise individualized heparin dose response titration assay for heparin and protamine management. Retrospective analysis of blood product usage pre-implementation, post-CPB changes and post-Hemostasis Management System (HMS) implementation was done to determine the effectiveness of the blood conservation strategies. Statistically significant decrease in packed red blood cells, fresh frozen plasma, cryoprecipitate, and platelet usage over the stepped implementation of both technologies was observed. New oxygenator and centrifugal pump technologies reduced active circuitry volume and caused less damage to blood cells. Individualizing heparin and protamine dosing to a patient using the HMS led to transfusion reductions as well. Overall trends toward reductions in hospital length of stay and intensive care unit stay, and as a result, blood product cost and total hospitalization cost are positive over the period of implementation of both CPB circuit changes and HMS implementation. Although they are multifactorial in nature, these trends provide positive enforcement to the changes implemented.

This study examines a large cohort of HCC patients in an effort to define the factors impacting clinical outcomes in pediatric HCC patients compared to adults. Methods. Demographic and clinical data on 63,771 HCC patients (257 pediatric patients ≤ 19 and 63,514 adult patients age ≥ 20 were abstracted from the SEER database (1973–2011. Results. HCC was more common among males (59.5% pediatric and 75.1% adults and Caucasians (50.4% and 50.5%, p 4 cm in size (79.6% versus 62.0%, p=0.02. Pediatric HCC patients undergoing surgery (13.107 versus 8.324 years, p4 cm in Caucasian males. Children with HCC achieve significantly longer mean overall survival compared to adults with HCC, primarily attributable to the more favorable fibrolamellar histologic variant, and more aggressive surgical intervention, which significantly improves survival.

    To evaluate the clinical and patient-reported outcome of all-ceramic zirconia implant supported fixed dental prostheses (FDPs) 5 years after implant installation. Thirteen patients were treated with two terminally placed one-piece zirconia implants for a three-unit FDP each. The FDPs consisted of a CAD/CAM-fabricated zirconia framework over-pressed with a fluor-apatite veneering ceramic and were adhesively cemented. Survival and success were assessed by applying modified US Public Health Service (USPHS) criteria and preparation of Kaplan-Meier (KM) plots. Alpha and Bravo ratings were accepted for success (among others including small area veneer chippings and occlusal roughness), whereas Charlie ratings allowing for intra-oral correction (e.g., polishing) were accepted for survival. Furthermore, patient-reported outcome measures (PROMs) were analyzed with the help of visual analogue scales (VAS). Wilcoxon matched-pairs signed-rank test (USPHS criteria) and linear mixed models (PROMs) were used to evaluate time effects on response variables. All patients were available 61.8 ± 1.1 months after implant installation (53.6 ± 3.1 months after final prosthesis insertion). FDP survival was 100%. Significant incidence of veneer chipping (p = .0096) and occlusal roughness (p = .0019) was observed. Charlie rated extent of both phenomena resulted in a KM success estimate of 38.5% (95% CI: 14.1%-62.8%; seven FDPs with obvious roughness, three of them with extended veneer chipping). Compared with the pre-treatment assessments (30%-81% of satisfaction), all surveys at prosthetic delivery showed significantly improved VAS scores (66%-93%; p ≤ .038), except for speech (p = .341). Concerning function, esthetics and self-esteem, no decrease in satisfaction could be observed until the end of follow-up (90%-96%; p ≥ .057), whereas perception of sense (92%) and speech (95%) increased over time (p ≤ .030). Occurrence of technical complications did not correlate

    The 21-gene Recurrence Score® (RS) assay is a validated prognostic/predictive tool in ER + early-stage breast cancer. However, clinical outcome data from prospective studies in RS ≥ 11 patients are lacking, as are relevant real-life clinical practice data. In this retrospective analysis of a prospectively designed registry, we evaluated treatments/clinical outcomes in patients undergoing RS-testing through Clalit Health Services. The analysis included N0 ER + HER2-negative breast cancer patients who were RS-tested from 1/2006 through 12/2010. Medical records were reviewed to verify treatments/recurrences/survival. The cohort included 1801 patients (median follow-up, 6.2 years). Median age was 60 years, 50.4% were grade 2 and 81.1% had invasive ductal carcinoma; 48.9% had RS < 18, 40.7% RS 18-30, and 10.4% RS ≥ 31, with chemotherapy use of 1.4, 23.7, and 87.2%, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 0.8, 3.0, and 8.6%, for patients with RS < 18, RS 18-30 and RS ≥ 31, respectively; the corresponding 5-year Kaplan-Meier estimates for breast cancer death were 0.0, 0.9, and 6.2%. Chemotherapy-untreated patients with RS < 11 ( n  = 304) and 11-25 ( n  = 1037) (TAILORx categorizatio n ) had 5-year Kaplan-Meier estimates for distant recurrence risk/breast cancer death of 1.0%/0.0% and 1.3%/0.4%, respectively. Our results extend those of the prospective TAILORx trial: the 5-year Kaplan-Meier estimates for distant recurrence and breast cancer death rate for the RS < 18 patients were very low supporting the use of endocrine therapy alone. Furthermore, in chemotherapy-untreated patients with RS 11-25 (where TAILORx patients were randomized to chemoendocrine or endocrine therapy alone), 5-year distant recurrence rates were also very low, suggesting that chemotherapy would not have conferred clinically meaningful benefit.

    Japan Nuclear Fuel Ltd. (hereafter, JNFL) MOX Fuel Fabrication Plant (hereafter, J-MOX) is what fabricates MOX fuel for domestic light water power plants. Development of design concept of J-MOX was started mid 90's and the frame of J-MOX process was clarified around 2000 including adoption of MIMAS process as apart of J-MOX powder process. JNFL requires to take an answer to any technical question that has not been clarified ever before by world's MOX and/or Uranium fabricators before it commissions equipment procurement. J-MOX is to be constructed adjacent to the Rokkasho Reprocessing Plant (RRP) and to utilize MH-MOX powder recovered at RRP. The combination of the MIMAS process and the MH-MOX powder is what has never tried in the world. Therefore JNFL started a series of confirmation tests of which the most important is the powder test to confirm the applicability of MH-MOX powder to the MIMAS process. The MH-MOX powder, consisting of 50% plutonium oxide and 50% uranium oxide, originates JAEA development utilizing microwave heating (MH) technology. The powder test started with laboratory scale small equipment utilizing both uranium and the MOX powder in 2000, left a solution to tough problem such as powder adhesion onto equipment, and then was followed by a large scale equipment test again with uranium and the MOX powder. For the MOX test, actual size equipment within glovebox was manufactured and installed in JAEA plutonium fuel center in 2005, and based on results taken so far an understanding that the MIMAS equipment, with the MH-MOX powder, can present almost same quality MOX pellet as what is introduced as fabricated in Europe was developed. The test was finished at the end of Japanese fiscal year (JFY) 2007, and it was confirmed that the MOX pellets fabricated in this test were almost satisfied with the targeted specifications set for domestic LWR MOX fuels.

    We analyzed the change of aesthetic outcome (AO) over time and explored factors characterizing poor AO after breast-conserving surgery (BCS). This prospective single-center cohort study included 849 patients preoperatively planned for BCS between September 2007 and December 2011. Long-term follow-up was made once in 2013. AO was measured by the Aesthetic Status (AS) of the Breast Cancer Treatment Outcome Scale questionnaire. Clinical, surgical, and pathologic variables were evaluated to identify predictors of poor AO. We applied single factor variance analyses and univariable logistic regression analyses for outcome analysis. The long-term follow-up rate in 2013 was 73 % (621 nonrecurrent with final BCS). A poor or fair AO was reported in 30 (4.8 %) and 98 (15.8 %) of these 621 patients, respectively. Single factor variance analysis showed a negative impact of higher specimen weight on AO (p procedures.

    Positive patient expectations are often believed to be associated with greater benefits from complementary and alternative medicine (CAM) treatments. However, clinical studies of CAM treatments for chronic pain have not consistently supported this assumption, possibly because of differences in definitions and measures of expectations. The goal of this qualitative paper is to provide new perspectives on the outcome expectations of patients prior to receiving CAM therapies for chronic low back pain. We conducted semi-structured interviews with 64 individuals receiving massage, chiropractic, acupuncture or yoga for chronic low back pain. Interviews were recorded and transcribed. Transcripts were analyzed by a team of experienced qualitative researchers using an immersion/crystallization approach to coding and analysis. Overall, participants' expectations of treatment outcomes tended to cluster in four key domains: pain relief, improved function (including an increase in ability to engage in meaningful activities), improved physical fitness, and improved overall well-being (including mental well-being). Typically, patients had modest expectations for outcomes from treatment. Furthermore, outcome expectations were complex on several levels. First, the concept of expectations overlapped with several related concepts; in particular, hopes. Participants sometimes used expectations and hopes interchangeably and at other times made clear distinctions between these two terms depending on context. A related finding was that participants were cautious about stating that they expected positive outcomes. Finally, participants articulated strong interrelationships among the four key domains and often discussed how changes in one domain might affect other domains. Overall, these findings contribute to a growing body of literature exploring the role of expectations in patient outcomes. This paper provides important guidance that may help refine the way treatment expectations are

    Despite advances in treatment of people living with HIV, morbidity and mortality remains unacceptably high in sub-Saharan Africa, largely due to parallel epidemics of poverty and food insecurity. We conducted a pilot cluster randomized controlled trial (RCT) of a multisectoral agricultural and microfinance intervention (entitled Shamba Maisha) designed to improve food security, household wealth, HIV clinical outcomes and women's empowerment. The intervention was carried out at two HIV clinics in Kenya, one randomized to the intervention arm and one to the control arm. HIV-infected patients >18 years, on antiretroviral therapy, with moderate/severe food insecurity and/or body mass index (BMI) loan (~$150) to purchase the farming commodities, 2) a micro-irrigation pump, seeds, and fertilizer, and 3) trainings in sustainable agricultural practices and financial literacy. Enrollment of 140 participants took four months, and the screening-to-enrollment ratio was similar between arms. We followed participants for 12 months and conducted structured questionnaires. We also conducted a process evaluation with participants and stakeholders 3-5 months after study start and at study end. Baseline results revealed that participants at the two sites were similar in age, gender and marital status. A greater proportion of participants at the intervention site had a low BMI in comparison to participants at the control site (18% vs. 7%, p = 0.054). While median CD4 count was similar between arms, a greater proportion of participants enrolled at the intervention arm had a detectable HIV viral load compared with control participants (49% vs. 28%, respectively, p loans, agricultural challenges due to weather patterns, and a challenging partnership with the microfinance institution. We expect the results from this pilot study to provide useful data on the impacts of livelihood interventions and will help in the design of a definitive cluster RCT.

    Ground-level fall is the most common cause of traumatic intracranial hemorrhage (TICH) in the elderly, and is a major cause of morbidity and mortality in that population. A retrospective study was carried out to evaluate whether the use of warfarin/low-dose aspirin (LDA) is predictive of unfavorable outcomes in geriatric patients who sustain a fall-induced TICH. Charts of 76 geriatric patients (≥ 65 years-of-age) with fall-induced TICH were reviewed. The number of patients taking warfarin and LDA was 12 and 21, respectively, whereas the other 43 took neither medication (non-user group). The frequency of patients with unfavorable outcomes (Glasgow Outcome Scale score of 1-3) at discharge was calculated. Furthermore, variables predictive of unfavorable outcomes were identified by logistic regression analysis. The frequency of patients with unfavorable outcomes was 75% in the warfarin group, 33% in the LDA group and 27% in the non-user group, respectively. The risk of having unfavorable outcomes was significantly higher in the warfarin group compared with the LDA group (P = 0.03) and non-user group (P fall-induced TICH. The risk of TICH should be communicated properly to elderly taking warfarin. The information might be important not only to trauma surgeons who take care of injured elderly, but also to geriatric physicians who prescribe warfarin/LDA to them. © 2012 Japan Geriatrics Society.

    The objective of this calculation is to establish an isotopic database to represent commercial spent nuclear fuel (CSNF) from pressurized water reactors (PWRs) in criticality analyses performed for the proposed Monitored Geologic Repository at Yucca Mountain, Nevada. Confirmation of the conservatism with respect to criticality in the isotopic concentration values represented by this isotopic database is performed as described in Section 3.5.3.1.2 of the ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2000). The isotopic database consists of the set of 14 actinides and 15 fission products presented in Section 3.5.2.1.1 of YMP 2000 for use in CSNF burnup credit. This set of 29 isotopes is referred to as the principal isotopes. The oxygen isotope from the UO 2 fuel is also included in the database. The isotopic database covers enrichments of 235 U ranging from 1.5 to 5.5 weight percent (wt%) and burnups ranging from approximately zero to 75 GWd per metric ton of uranium (mtU). The choice of fuel assembly and operating history values used in generating the isotopic database are provided is Section 5. Tables of isotopic concentrations for the 29 principal isotopes (plus oxygen) as a function of enrichment and burnup are provided in Section 6.1. Results of the confirmation of the conservatism with respect to criticality in the isotopic concentration values are provided in Section 6.2

    This is the final report of the NUMO-LBNL collaborative project: Feature Detection, Characterization and Confirmation Methodology under NUMO-DOE/LBNL collaboration agreement, the task description of which can be found in the Appendix. We examine site characterization projects from several sites in the world. The list includes Yucca Mountain in the USA, Tono and Horonobe in Japan, AECL in Canada, sites in Sweden, and Olkiluoto in Finland. We identify important geologic features and parameters common to most (or all) sites to provide useful information for future repository siting activity. At first glance, one could question whether there was any commonality among the sites, which are in different rock types at different locations. For example, the planned Yucca Mountain site is a dry repository in unsaturated tuff, whereas the Swedish sites are situated in saturated granite. However, the study concludes that indeed there are a number of important common features and parameters among all the sites--namely, (1) fault properties, (2) fracture-matrix interaction (3) groundwater flux, (4) boundary conditions, and (5) the permeability and porosity of the materials. We list the lessons learned from the Yucca Mountain Project and other site characterization programs. Most programs have by and large been quite successful. Nonetheless, there are definitely 'should-haves' and 'could-haves', or lessons to be learned, in all these programs. Although each site characterization program has some unique aspects, we believe that these crosscutting lessons can be very useful for future site investigations to be conducted in Japan. One of the most common lessons learned is that a repository program should allow for flexibility, in both schedule and approach. We examine field investigation technologies used to collect site characterization data in the field. An extensive list of existing field technologies is presented, with some discussion on usage and limitations

    An earlier published series of neoadjuvant radiochemotherapy (NRT-CHX) in locally advanced noninflammatory breast cancer (LABC) has now been updated with a follow-up of more than 15 years. Long-term outcome data and predictive factors for pathologic complete response (pCR) were analyzed. Patients and methods: During 1991-1998, 315 LABC patients (cT1-cT4/cN0-N1) were treated with NRT-CHX. Preoperative radiotherapy (RT) consisted of external beam radiation therapy (EBRT) of 50 Gy (5 x 2 Gy/week) to the breast and the supra-/infraclavicular lymph nodes combined with an electron boost in 214 cases afterwards or - in case of breast conservation - a 10-Gy interstitial boost with 192 Ir afterloading before EBRT. Chemotherapy was administered prior to RT in 192 patients, and concomitantly in 113; 10 patients received no chemotherapy. The update of all follow-up ended in November 2011. Age, tumor grade, nodal status, hormone receptor status, simultaneous vs. sequential CHX, and the time interval between end of RT and surgery were examined in multivariate terms with pCR and overall survival as end point. Results: The total pCR rate after neoadjuvant RT-CHX reached 29.2%, with LABC breast conservation becoming possible in 50.8% of cases. In initially node-positive cases (cN+), a complete nodal response (pN0) after NRT-CHX was observed in 56% (89/159). The multivariate analysis revealed that a longer time interval to surgery increased the probability for a pCR (HR 1.17 [95% CI 1.05-1.31], p 2 months) increases the probability of pCR after NRT-CHX.

Cariogram is a well-recognized algorithm-based software program based on different caries-related risk factors and intended to aid clinicians in performing more objective and consistent dental caries risk assessments. This type of approach precedes the diagnosis of caries and allows the dentist to identify at-risk patients and then take appropriate preventive measures before caries develop further. One of the etiological factors favoring the development of dental caries is the mutans streptococci. These acidogenic dental plaque inhabitants can be effectively antagonized by the activity of bacteriocins released by the probiotic Streptococcus salivarius M18 (salivarius M18. Moreover, salivarius M18 after colonizing the human oral mucosa produces the enzymes dextranase and urease that are able to counteract plaque formation and saliva acidity, respectively. Seventy-six subjects at high risk of dental caries were randomized and then either treated or not treated for 90 days with an oral formulation containing the oral probiotic salivarius M18 (Carioblis®. The results indicate that the use of salivarius M18 increases the chances of avoiding new dental caries development in children, and its application could be proposed as a new tool in the dentist's armory to be adopted in subjects considered at high risk on the basis of their Cariogram outcome.

    Purpose: We hypothesized that patients with oropharyngeal cancer treated with intensity modulated proton therapy (IMPT) would have lower symptom burdens, as measured by patient-reported outcome (PRO) surveys, than patients treated with intensity modulated photon therapy (IMRT). Methods and Materials: Patients were treated for oropharyngeal cancer from 2006 to 2015 through prospective registries with concurrent chemotherapy and IMPT or chemotherapy and IMRT and completed the MD Anderson Symptom Inventory for Head and Neck Cancer (MDASI-HN) module at various times before treatment (baseline), during treatment (acute phase), within the first 3 months after treatment (subacute phase), and afterward (chronic phase). Individual symptoms and the top 5 and top 11 most severe symptoms were summarized and compared between the radiation therapy modalities. Results: PRO data were collected and analyzed from 35 patients treated with chemotherapy and IMPT and from 46 treated with chemotherapy and IMRT. The baseline symptom burdens were similar between both groups. The overall top 5 symptoms were food taste problems (mean score 4.91 on a 0-10 scale), dry mouth (4.49), swallowing/chewing difficulties (4.26), lack of appetite (4.08), and fatigue (4.00). Among the top 11 symptoms, changes in taste and appetite during the subacute and chronic phases favored IMPT (all P<.048). No differences in symptom burden were detected between modalities during the acute and chronic phases by top-11 symptom scoring. During the subacute phase, the mean (±standard deviation) top 5 MDASI scores were 5.15 ± 2.66 for IMPT versus 6.58 ± 1.98 for IMRT (P=.013). Conclusions: According to the MDASI-HN, symptom burden was lower among the IMPT patients than among the IMRT patients during the subacute recovery phase after treatment. A prospective randomized clinical trial is underway to define the value of IMPT for the management of head and neck tumors.

    Patients with severe, symptomatic aortic stenosis, who do not undergo valve replacement surgery have a poor long-term prognosis. Limited data exist on the medical resource utilization and costs during the final stages of the disease. We used data from the 2003 Medicare 5% standard analytic files to identify patients with aortic stenosis and a recent hospitalization for heart failure, who did not undergo valve replacement surgery within the ensuing 2 calendar quarters. These patients (n=2150) were considered to have medically managed severe aortic stenosis and were tracked over 5 years to measure clinical outcomes, medical resource use, and costs (from the perspective of the Medicare Program). The mean age of the cohort was 82 years, 64% were female, and the estimated logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) (a measure of predicted mortality with cardiac surgery) was 17%. During 5 years of follow-up, overall mortality was 88.4% with a mean survival duration of 1.8 years. During this time period, patients experienced an average of 4.4 hospital admissions, 52% were admitted to skilled nursing care, and 28% were admitted to hospice care. The total 5-year costs were $63 844 per patient, whereas mean annual follow-up costs (excluding the index quarter) per year alive were $29 278. Elderly patients with severe aortic stenosis undergoing medical management have limited long-term survival and incur substantial costs to the Medicare Program. These results have important implications for policy makers interested in better understanding the cost-effectiveness of emerging treatment options such as transcatheter aortic valve replacement.

    There is limited data regarding outcomes of Ewing's sarcoma family of tumors in adolescents and adults compared with the same tumors in childhood. The aim of the study was to analyze prognostic factors and treatment results in a cohort of adolescents and adults with non-metastatic skeletal Ewing's sarcoma family of tumors. From 1992-2008, 90 adolescents and adults with Ewing's sarcoma family of tumors of the bone were referred to our institution. Sixty-five (72%) non-metastatic patients with analyzable data and treated in our institution were retrospectively evaluated. All patients were treated with alternated chemotherapy regimens administered every 3 weeks. The local treatment modality was selected according to tumor and patient characteristics. The median age was 21 years (range, 13-50). Most patients (74%) were >17 years of age. Forty-six percent of the tumors were located in the extremities. Local therapy was surgery in 45 patients and radiotherapy alone in 19 patients. Twenty-one patients received preoperative and 13 patients postoperative radiotherapy. Median follow-up was 43 months (range, 7-167). The 5-year event-free and overall survival rates for all patients were 44% and 49%, respectively. On univariate survival analysis, event-free and overall survival were worse for patients >17 years of age, tumor size >8 cm in diameter, an axial location, positive surgical margins, and poor histopathological response (<90% necrosis). Age, tumor site and tumor size on event-free and overall survival remained significant on multivariate analysis. We identified age, tumor size, and tumor site as independent prognostic factors, in accord with the Western literature. These patients require novel treatment modalities.

    Does the incidence and/or indication(s) for emergency cesarean section differ if the pregnant woman has an immigrant background (IB)? Does a lack of language proficiency (communication problems) and a low acculturation level result in a longer decision-to-delivery interval (D-D interval)? Are neonates born to women with IB by emergency cesarean section in a poorer condition post delivery? Standardized interviews were carried out before or immediately after delivery in three Berlin obstetric hospitals. Questions were asked about the sociodemographic background and care aspects as well as about immigration and level of acculturation. Collected data were linked to information obtained from the expectant mother's antenatal records and to care data and perinatal data routinely recorded by the hospitals. Data was analyzed using regression models which adjusted for age, parity, and socio-economic status. The total patient population consisted of 7100 women (rate of response: 89.6%); of these women, 111 required emergency cesarean section (50 women without IB, 61 immigrant women). Risk factors such as late first antenatal check-up, gestational diabetes, pregnancy-induced hypertension, fetal macrosomia, smoking, and weight gain were similar in both patient cohorts. The incidence of and indications for emergency cesarean section and the D-D interval were similar for both groups. Limited German language proficiency and low levels of acculturation among immigrant women did not prolong the D-D interval. There were no statistically relevant differences between immigrant and non-immigrant cohorts with regard to adverse neonatal conditions (5-minute Apgar score ≤ 7, umbilical cord arterial pH cesarean section. The factor "immigrant background" did not affect the indication or obstetric outcome following emergency cesarean section.

    Purpose: To evaluate the practice process using the national average (Na); to compare differences in the process of care by age group; and to provide a preliminary outcome data for limited-stage small-cell lung cancer in Japan. Methods and Materials: The Patterns of Care Study conducted a nationwide survey of the care process for Stage I-III small-cell lung cancer in Japan. Patients were divided into three age groups: <65 years (younger group, n = 73); between 65 and 74 years (intermediate group, n = 81); and ≥75 years (elderly group, n = 20). Results: The NA for the total dose was 49.0 Gy, and for use of photon energy ≥6 MV, chemotherapy, and prophylactic cranial irradiation was 77.3%, 93.2%, and 1.69%, respectively. Age stratification had no impact on the variables of radiotherapy (RT) such as total dose and field size. Only 37% of patients received chemotherapy and thoracic RT concurrently. The proportion of patients who received chemotherapy and RT concurrently was 44%, 27%, and 25% of the younger, intermediate, and elderly groups, respectively (p = 0.029). Etoposide and cisplatin were less frequently used in the elderly group (≥75 years old). Overall survival at 3 years for the entire group was 26%. The 3-year survival rate was 30% in the younger group, 28% in the intermediate group, and 9% in the elderly group. Variables found to have a significant impact on survival by multivariate analysis were the use of chemotherapy (p = 0.030), age (p 0.032), and T stage (p = 0.042). Conclusion: Calculated NAs showed that the results of clinical study had favorably penetrated into the practice process in Japan. The results demonstrated that patient age significantly influenced the process of chemotherapy such as the use of etoposide and cisplatin for limited-stage small-cell lung cancer in Japan. More concurrent chemotherapy and thoracic RT and the application of prophylactic cranial irradiation for complete responders need to be investigated in the future

    Full Text Available Introduction: At Hiwa Cancer Hospital (Sulaymaniyah, Iraqi Kurdistan after the center was started by a cooperative project in June 2016, autologous transplantation was developed. Patients and Methods: To develop the project, the capacity-building approach was adopted, with on-site training and coaching of personnel, educational meetings, lectures, on-the-job training, and the implementation of quality management planning. Results: Here, we report initial results of peripheral-blood stem-cell mobilization and collection of the first 27 patients (age 12 to 61 years; 19 males and 8 females; multiple myeloma, n = 10; plasma cell leukemia, n = 1; Hodgkin lymphoma, n = 12; non-Hodgkin lymphoma, n = 3; and acute myeloid leukemia, n = 1. Only three (11.5% of 26 patients experienced a failure of mobilization. A median of 6.1 × 106/kg CD34-positive cells per patient were collected (range, 2.4 to 20.8, with two apheretic runs. Twenty-four patients underwent autologous transplantation. All but one transplantation engrafted fully and steadily, with 0.5 and 1.0 × 109/L polymorphonucleates on day 10.5 (range, 8 to 12 and day 11 (range, 9 to 15, respectively, and with 20 and 50 × 109/L platelets on day 13 (range, 10 to 17 and day 17 (range, 2 to 44, respectively. More than 95% of patients are projected to survive 1 year after autograft. Conclusion: These data are the result of an Italian effort to establish in Iraqi Kurdistan a leading center for hemopoietic stem-cell transplantation. The capacity building approach was used, with on-site training and coaching as instruments for the development of provider ability and problem solving. With future limitations for immigration, this method will be helpful, especially in the field of high-technology medicine.

    Management of pancreatic cancer (PC) in elderly patients is unknown; clinical trials exclude patients with comorbidities and those of extreme age. This study evaluated treatment patterns and survival outcomes in elderly PC patients using linked Surveillance, Epidemiology, and End Results (SEER) and Medicare data. Histology codes 8140, 8500, 8010, 8560, 8490, 8000, 8260, 8255, 8261, 8263, 8020, 8050, 8141, 8144, 8210, 8211, or 8262 in Medicare Parts A and B were identified. Data regarding demographic, characteristics, treatments, and vital status between 1998 and 2009 were collected from the SEER. Determinants of treatment receipt and overall survival were examined using logistic regression and Cox proportional hazards models, respectively. A total of 5,975 patients met inclusion. The majority of patients were non-Hispanic whites (85%) and female (55%). Most cases presented with locoregional stage disease (74%); 41% received only chemotherapy, 30% chemotherapy and surgery, 10% surgery alone, 3% radiation, and 16% no cancer-directed therapy. Patients with more advanced cancer, older age, and those residing in areas of poverty were more likely to receive no treatment. Among patients 66-74 years of age with locoregional disease, surgery alone (hazard ratio [HR] = 0.54; 95% confidence interval [CI]: 0.39-0.74) and surgery in combination with chemotherapy (HR = 0.69; 95% CI: 0.53-0.91) showed survival benefit as compared with the no treatment group. Among patients ≥75 years of age with locoregional disease, surgery alone (HR = 2.04; 95% CI: 0.87-4.8) or in combination with chemotherapy (HR = 1.59; 95% CI: 0.87-2.91) was not associated with better survival. Treatment modality and survival differs by age and stage. Low socioeconomic status appears to be a major barrier to the receipt of PC therapy among Medicare patients. Elderly patients with cancer are under-represented on clinical trials and usually have comorbid illnesses. The management of elderly

    After choosing between uncertain options, one might get feedback on both the outcome of the chosen option and the outcome of the unchosen option (the alternative). Behavioral research has shown that in such cases people engage in outcome comparison, and that the alternative outcome influences the way one evaluates his own received outcome. Moreover, this influence differs whether one was responsible or not for the choice made. In two studies, we looked for the electrophysiological correlates of outcome comparison. Subjects chose one of two boxes shown on the screen, each box contained a gain or a loss. The alternative outcome was always revealed first, followed by the received outcome. In half of the trials the software picked one box instead of subjects. We tested whether the feedback-related negativity (FRN) and the P3 elicited by the received reflect outcome comparison. As expected, we found that the FRN and P3 were more positive when the received outcome was a gain (vs. a loss). The FRN and P3 were also sensitive to the value of the alternative outcome, but contrary to our predictions, they were more positive when the alternative outcome was a gain (vs. a loss). As the FRN and P3 are sensitive to expectations, we hypothesized that our findings might result from subjects' biased expectations: subjects might have wrongly believed that a good (bad) alternative outcome signaled a bad (good) received outcome. This hypothesis, coined as the Alternative Omen Effect, was confirmed in parallel in a series of behavioral experiments: people see an illusory negative correlation between the uncorrelated outcomes of choice options (reported in Marciano-Romm et al. (2016)). A challenge for future research will be to disentangle the effects of expectation from those of outcome comparison. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The present study aimed to evaluate the long-term stability of esthetic outcomes of soft tissue around maxillary anterior single-tooth implants after 10-to-12 years of loading. Patients who had been treated for single-tooth implants in the anterior maxilla between February 2000 and July 2002 were invited to participate in the study. All implants had been placed according to delayed implant placement and conventional loading protocols without any connective tissue graft or papilla preservation flaps. Pink Esthetic Score (PES) was rated using standardized clinical photographs to assess the esthetic outcomes of the implant treatment at the time of crown placement and at time of follow-up examination which was at least 10 years after the crown placement. A total of 19 patients were included. The mean score of PES was 11.63 (SD 1.61; range 7-14) at baseline. After 10-to-12 years of function, a mean PES score of 11.05 (SD 2.09; range 6-14) was recorded. No significant differences were found in the esthetic outcomes, categorized based on clinically relevant levels, between the baseline and follow-up session (p>0.05). Within limitation of the present study, it can be concluded that the esthetic outcomes of soft tissue around the maxillary anterior single-tooth implants placed using conventional implant placement technique remained stable in the long-term.

    To assess differences among USA ethnic groups in psychological status of adult family members (FMs) and their involvement with the diabetes of another adult. Data are from the FM survey of the USA DAWN2 study, including 105 White non-Hispanics, 47 African Americans, 46 Hispanic Americans and 40 Chinese Americans. All FMs lived with and cared for an adult with diabetes. Analysis of covariance controlled for respondent and patient characteristics to assess ethnic group differences (P ethnic minority groups. African Americans reported the highest well-being and lowest negative life impact, Chinese Americans reported the most diabetes burden, Hispanic Americans reported the highest distress. There were no ethnic group differences in QoL. Ethnic minority FMs reported having more involvement with diabetes, greater support success, and more access to a diabetes support network than White non-Hispanics. Higher FM diabetes involvement was associated with negative psychological outcomes, while diabetes education, support success and diabetes support network size were associated with better psychological outcomes. Potential limitations are the sample sizes and representativeness. Minority ethnic FMs experienced both advantages and disadvantages in psychological outcomes relative to each other and to White non-Hispanics. Ethnic minority FMs had more involvement in diabetes care, support success and support from others, with the first associated with worse and the latter two with better psychological outcomes. Additional studies are needed with larger samples and broader representation of ethnic groups to better understand these associations and identify areas for intervention.

    Malnutrition and weight loss are common features of patients with inflammatory bowel disease (IBD). To explore the impact of inadequate gestational weight gain (GWG) on adverse outcomes among IBD mothers in the prospective US pregnancy in Inflammatory Bowel Disease and Neonatal Outcomes (PIANO) cohort. The PIANO cohort comprises 559 and 363 pregnant mothers with Crohn's disease (CD) and ulcerative colitis (UC), respectively, enrolled between 2006 and 2014. The mothers were followed during and after pregnancy to ascertain medication, measurement of disease activity and complications during pregnancy and at delivery. Inadequate GWG was based on US Institute of Medicine recommendations. The associations between inadequate GWG and adverse pregnancy outcomes in maternal IBD were analyzed, adjusted for diabetes, hypertension, smoking, maternal age, education, and disease activity. Maternal CD and UC with inadequate GWG had a 2.5-fold increased risk of preterm birth (OR 2.5, CI 1.3, 4.9 and OR 2.5, CI 1.2, 5.6). Furthermore, an increased risk of intrauterine growth restriction and a trend for small for gestational age were demonstrated in CD but not in UC (OR 3.3, CI 1.1, 10.0, OR 4.5, CI 0.8, 24.3, p = 0.08). Flares increased risk of inadequate GWG (OR 1.6, CI 1.2, 2.3, p = 0.002) but did not change the associations between inadequate GWG and adverse pregnancy outcomes in our models. The US PIANO cohort demonstrated that inadequate GWG was a strong independent predictor of adverse pregnancy outcomes in IBD mothers.

    Patients with head and neck cancer experience loss of weight and muscle mass, decreased functioning, malnutrition, depression, and declines in quality of life during and after treatment. The purpose of this exploratory randomized study was to determine the optimal timing for the initiation of a lifestyle and progressive resistance exercise training intervention (during or after radiation therapy), as determined by intervention adherence and by comparing between-group outcomes across 24 weeks. Sixty patients with head and neck cancer were randomized to engage in a 12-week lifestyle intervention and progressive resistance-training program either during radiation treatment or immediately after completion. The primary outcome of body composition--specifically, lean body mass, body mass index, and body fat--as well as secondary outcomes of fitness, quality of life, depression, and nutrition status were evaluated. The progressive resistance-training intervention carried out during treatment did not significantly influence the primary outcome of body composition, despite a significant increase in weekly physical activity reported by the intervention group. A small-to-medium intervention effect was noted for some secondary outcomes, including fitness, quality of life, and nutrition status. Regardless of whether patients received the immediate or delayed progressive resistance-training intervention, the analysis revealed a main effect of time on body composition, fitness, quality of life, depression, and nutritional scores. Although the intervention during treatment did not reduce the loss of lean body mass, delaying the exercise program until after treatment completion was associated with improved intervention adherence, a finding with important clinical implications. © 2016 American Cancer Society.

    In 2009, national legislation promoted wide-spread adoption of electronic health records (EHRs) across US hospitals; however, the association of EHR use with quality of care and outcomes after acute myocardial infarction (AMI) remains unclear. Data on EHR use were collected from the American Hospital Association Annual Surveys (2007-2010) and data on AMI care and outcomes from the National Cardiovascular Data Registry Acute Coronary Treatment and Interventions Outcomes Network Registry-Get With The Guidelines. Comparisons were made between patients treated at hospitals with fully implemented EHR (n=43 527), partially implemented EHR (n=72 029), and no EHR (n=9270). Overall EHR use increased from 82.1% (183/223) hospitals in 2007 to 99.3% (275/277) hospitals in 2010. Patients treated at hospitals with fully implemented EHRs had fewer heparin overdosing errors (45.7% versus 72.8%; P<0.01) and a higher likelihood of guideline-recommended care (adjusted odds ratio, 1.40 [confidence interval, 1.07-1.84]) compared with patients treated at hospitals with no EHR. In non-ST-segment-elevation AMI, fully implemented EHR use was associated with lower risk of major bleeding (adjusted odds ratio, 0.78 [confidence interval, 0.67-0.91]) and mortality (adjusted odds ratio, 0.82 [confidence interval, 0.69-0.97]) compared with no EHR. In ST-segment-elevation MI, outcomes did not significantly differ by EHR status. EHR use has risen to high levels among hospitals in the National Cardiovascular Data Registry. EHR use was associated with less frequent heparin overdosing and modestly greater adherence to acute MI guideline-recommended therapies. In non-ST-segment-elevation MI, slightly lower adjusted risk of major bleeding and mortality were seen in hospitals implemented with full EHRs; however, in ST-segment-elevation MI, differences in outcomes were not seen. © 2015 American Heart Association, Inc.

    To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis.We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition.Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002-1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063-0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338-1.934, P = .663).Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome.

    Background/purpose: Bare metal stents (BMS) have similar rates of death and myocardial infarction (MI) compared to drug-eluting stents (DES). DES lower repeat revascularization rates compared to BMS, but may have higher rates of late stent thrombosis (ST) potentially due to impaired endothelialization requiring longer dual anti-platelet therapy (DAPT). OMEGA evaluated a novel BMS designed to have improved deliverability and radiopacity, in comparison to currently available platforms. Methods/materials: OMEGA was a prospective, multicenter, single-arm study enrolling 328 patients at 37 sites (US and Europe). Patients received the OMEGA stent (bare platinum chromium element stent) for the treatment of de novo native coronary artery lesions (≤ 28 mm long; diameter ≥ 2.25 mm to ≤ 4.50 mm). The primary endpoint was 9-month target lesion failure (TLF: cardiac death, target vessel-related MI, target lesion revascularization [TLR]) compared to a prespecified performance goal (PG) based on prior generation BMS. All major cardiac events were independently adjudicated. DAPT was required for a minimum of 1 month post procedure. Results: In the OMEGA study, the mean age was 65; 17% had diabetes mellitus. The primary endpoint was met; 9 month TLF rate was 11.5%, and the upper 1-sided 95% confidence bound of 14.79% was less than the prespecified PG of 21.2% (p < 0.0001). One-year event rates were low including a TLF rate of 12.8% and an ST rate of 0.6% at 12 months. Conclusions: One-year outcomes of OMEGA show low rates of TLF, revascularization and ST. This supports safety and efficacy of the OMEGA BMS for the treatment of coronary artery disease. - Highlights: • The OMEGA study evaluated a novel platinum chromium bare metal stent. • OMEGA enrolled 328 patients at 37 sites (US and Europe). • The primary endpoint of 9 month target lesion failure was 11.5%. • One-year event rates were low including an ST rate of 0.6% at 12 months.

    Dose-escalated (DE) radiotherapy in the setting of localized prostate cancer has been shown to improve biochemical disease-free survival (bDFS) in several studies. In the same group of patients, androgen deprivation therapy (ADT) has been shown to confer a survival benefit when combined with radiotherapy doses of up to 70 Gy; however, there is currently little long-term data on patients who have received high-dose intensity-modulated radiotherapy (IMRT) with ADT. We report the long-term outcomes in a large cohort of patients treated with the combination of DE image-guided IMRT (IG-IMRT) and ADT. Patients with localized prostate cancer were identified from a centralized database across an integrated cancer center. All patients received DE IG-IMRT, combined with ADT, and had a minimum follow up of 12 months post-radiotherapy. All relapse and toxicity data were collected prospectively. Actuarial bDFS, metastasis-free survival, prostate cancer-specific survival, and multivariate analyses were calculated using the SPSS v20.0 statistical package. Seven hundred and eighty-two eligible patients were identified with a median follow up of 46 months. Overall, 4.3% of patients relapsed, 2.0% developed distant metastases, and 0.6% died from metastatic prostate cancer. At 5-years, bDFS was 88%, metastasis-free survival was 95%, and prostate cancer-specific survival was 98%. Five-year grade 2 genitourinary and gastrointestinal toxicity was 2.1% and 3.4%, respectively. No grade 3 or 4 late toxicities were reported. Pretreatment prostate specific antigen (P=0.001) and Gleason score (P=0.03) were significant in predicting biochemical failure on multivariate analysis. There is a high probability of tumor control with DE IG-IMRT combined with androgen deprivation, and this is a technique with a low probability of significant late toxicity. Our long term results corroborate the safety and efficacy of treating with IG-IMRT to high doses and compares favorably with published series for

    Tofacitinib is an oral Janus kinase inhibitor being investigated for psoriasis. A Phase 3 withdrawal/re-treatment study (NCT01186744; OPT Retreatment) showed tofacitinib re-treatment was effective in patients with chronic plaque psoriasis. To describe the effects of tofacitinib withdrawal/re-treatment on health-related quality of life (HRQoL) and disease symptoms measured by patient-reported outcomes (PROs). The study was divided into initial treatment, treatment withdrawal, and re-treatment periods. Initial treatment: patients were randomized to receive tofacitinib 5 (n = 331) or 10 mg (n = 335) BID for 24 weeks. Treatment withdrawal: patients who achieved both ≥ 75% reduction in Psoriasis Area and Severity Index (PASI) score from baseline and Physician's Global Assessment of 'clear'/'almost clear' at Week (W)24 received placebo (withdrawal) or the previous dose (continuous treatment). Re-treatment: at relapse (> 50% loss of W24 PASI response) or at W40, patients received their initial tofacitinib dose. PROs included: Dermatology Life Quality Index (DLQI), Itch Severity Item (ISI), Short Form-36 (SF-36) and Patient's Global Assessment (PtGA). After initial treatment with tofacitinib 5 and 10 mg BID, substantial and significant improvements were reported for mean DLQI (baseline: 12.6 and 12.6; W24: 5.1 and 2.6) and ISI (baseline: 6.7 and 6.9; W24: 2.9 and 1.6). Patients continuously treated with tofacitinib 5 and 10 mg BID maintained those improvements through Week 56 (DLQI: 3.0 and 2.1; ISI: 2.3 and 1.4). By W40, patients withdrawn from tofacitinib 5 and 10 mg BID showed worsening in DLQI (5.0 and 6.2) and ISI (3.7 and 4.0) scores; improvements were regained upon re-treatment (W56, DLQI: 3.4 and 2.4; ISI: 2.2 and 1.6). Similar results were reported for PtGA and SF-36. Continuous tofacitinib treatment provided sustained improvement in HRQoL and disease symptoms. Patients randomized to treatment withdrawal lost initial improvements. Upon re-treatment, improvements

    SOX9 is a widely expressed transcription factor playing several relevant functions during development and essential for testes differentiation. It is considered to be the direct target gene of the protein encoded by SRY and its overexpression in an XX murine gonad can lead to male development in the absence of Sry. Recently, a family was reported with a 178 kb duplication in the gene desert region ending about 500 kb upstream of SOX9 in which 46,XY duplicated persons were completely normal and fertile whereas the 46,XX ones were males who came to clinical attention because of infertility. We report a family with two azoospermic brothers, both 46,XX, SRY negative, having a 96 kb triplication 500 kb upstream of SOX9. Both subjects have been analyzed trough oligonucleotide array-CGH and the triplication was confirmed and characterised through qPCR, defining the minimal region of amplification upstream of SOX9 associated with 46,XX infertile males, SRY negative. Our results confirm that even in absence of SRY, complete male differentiation may occur, possibly driven by overexpression of SOX9 in the gonadal ridge, as a consequence of the amplification of a gene desert region. We hypothesize that this region contains gonadal specific long-range regulation elements whose alteration may impair the normal sex development. Our data show that normal XX males, with alteration in copy number or, possibly, in the critical sequence upstream to SOX9 are a new category of infertility inherited in a dominant way with expression limited to the XX background.

    Neutron Activation Analysis (NAA) based on neutron capture by nuclides. Of the various possibilities of radionuclides that occur, radionuclides and gamma radiation which provides the identity of the element were analyzed and the best sensitivity should be determined. Confirmation for elements in sediment samples was done theoretically and experimentally. The result of confirmation shows that Al, V, Cr K, Na, Ca and Zn were analyzed based on radionuclides of Al-28, V-52, Cr-51 , K-42, Na-24, Ca-48, Zn-65. Elements of Mg, Mn, Fe, Co were analyzed based on radionuclides of Mg-27, Mn-56, Fe-59, Co-60 through peak which the highest value of combined probability of radiation emission and efficiency. Cu can be analyzed through Cu-64 or Cu-66, but the second is more sensitive. Detection limit is determined at a certain measurement conditions carried out by a laboratory. Detection limit in the NAA is determined based on the Compton continue area by Curie method. The detection limit of Al, V, Ca, Mg, Mn, As, K, Na, Mg, Ce, Co, Cr, Fe, La, Sc, and Zn in sediment samples are 240, 27, 4750, 2600, 21, 3.3 , 75, 1.4, 1.8, 0.5, 2.7, 29, 1, 0.05, and 37 ppm. Analysis of Cu in sediments which concentrations of 98.6 ppm, Cu-66 is not detected. Tests using pure standard solutions of Cu obtained detection limit of 0.12 µg, or 7.9 ppm in samples of 15 mg. In general, the detection limit obtained was higher than the detection limit of the reference, it was caused by the differences in the sample matrix and analytical conditions. (author)

    The isolation of sulfhydryl oxidase from bovine milk in a suitably pure form for sequencing was carried out by transient covalent affinity chromatography of diafiltered whey using cysteinylsuccinamidopropyl-glass as matrix. The glutathione-eluted proteins were separated by SDS-PAGE. By radiolabeling the affinity chromatography-purified enzyme with [ 14 C]iodoacetate before subjecting to SDS-PAGE, the sulfhydryl oxidase band was identified, because sulfhydryl oxidase is known to be inactivated by alkylation of one sulfhydryl group per mole. The results confirmed that sulfhydryl oxidase corresponds to the 85 (± 5)-kDa band observed on SDS-PAGE. The protein band corresponding to radiolabeled sulfhydryl oxidase was recovered from SDS-PAGE gels by electrophoretic elution and by electroblotting on polyvinylidene difluoride membrane and subjected to gas phase sequencing. Precautions were taken during electrophoretic elution to prevent reactions that result in N-terminal blocking. Both methods of protein recovery yielded negative results when subjected to sequence analysis indicating that the N-terminus of sulfhydryl oxidase is blocked

    Population-based information on the distribution of histologic diagnoses associated with skin biopsies is unknown. Electronic medical records (EMRs) enable automated extraction of pathology report data to improve our epidemiologic understanding of skin biopsy outcomes, specifically those of melanocytic origin. To determine population-based frequencies and distribution of histologically confirmed melanocytic lesions. A natural language processing (NLP)-based analysis of EMR pathology reports of adult patients who underwent skin biopsies at a large integrated health care delivery system in the US Pacific Northwest from January 1, 2007, through December 31, 2012. Skin biopsy procedure. The primary outcome was histopathologic diagnosis, obtained using an NLP-based system to process EMR pathology reports. We determined the percentage of diagnoses classified as melanocytic vs nonmelanocytic lesions. Diagnoses classified as melanocytic were further subclassified using the Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis (MPATH-Dx) reporting schema into the following categories: class I (nevi and other benign proliferations such as mildly dysplastic lesions typically requiring no further treatment), class II (moderately dysplastic and other low-risk lesions that may merit narrow reexcision with skin biopsies, performed on 47 529 patients, were examined. Nearly 1 in 4 skin biopsies were of melanocytic lesions (23%; n = 18 715), which were distributed according to MPATH-Dx categories as follows: class I, 83.1% (n = 15 558); class II, 8.3% (n = 1548); class III, 4.5% (n = 842); class IV, 2.2% (n = 405); and class V, 1.9% (n = 362). Approximately one-quarter of skin biopsies resulted in diagnoses of melanocytic proliferations. These data provide the first population-based estimates across the spectrum of melanocytic lesions ranging from benign through dysplastic to malignant. These results may serve as a foundation for future

    Metrological confirmation process must be designed and implemented to ensure that metrological characteristics of the measurement system meet metrological requirements of the measurement process. The aim of this paper is to present an alternative method to the traditional metrological requirements about the relationship between tolerance and measurement uncertainty, to develop such confirmation processes. The proposed way to metrological confirmation considers a given inspection task of the measurement process into the manufacturing system, and it is based on the Index of Contamination of the Capability, ICC. Metrological confirmation process is then developed taking into account the producer risks and economic considerations on this index. As a consequence, depending on the capability of the manufacturing process, the measurement system will be or will not be in adequate state of metrological confirmation for the measurement process.

    In preclinical testing of antituberculosis drugs, laboratory-adapted strains of Mycobacterium tuberculosis are usually used both for in vitro and in vivo studies. However, it is unknown whether the heterogeneity of M. tuberculosis stocks used by various laboratories can result in different outcomes in tests of antituberculosis drug regimens in animal infection models. In head-to-head studies, we investigated whether bactericidal efficacy results in BALB/c mice infected by inhalation with the laboratory-adapted strains H37Rv and Erdman differ from each other and from those obtained with clinical tuberculosis strains. Treatment of mice consisted of dual and triple drug combinations of isoniazid (H), rifampin (R), and pyrazinamide (Z). The results showed that not all strains gave the same in vivo efficacy results for the drug combinations tested. Moreover, the ranking of HRZ and RZ efficacy results was not the same for the two H37Rv strains evaluated. The magnitude of this strain difference also varied between experiments, emphasizing the risk of drawing firm conclusions for human trials based on single animal studies. The results also confirmed that the antagonism seen within the standard HRZ regimen by some investigators appears to be an M. tuberculosis strain-specific phenomenon. In conclusion, the specific identity of M. tuberculosis strain used was found to be an important variable that can change the apparent outcome of in vivo efficacy studies in mice. We highly recommend confirmation of efficacy results in late preclinical testing against a different M. tuberculosis strain than the one used in the initial mouse efficacy study, thereby increasing confidence to advance potent drug regimens to clinical trials.
