    Proteinuria is a common manifestation of chronic kidney disease (CKD), and there is a high incidence of CDK and its complications following renal transplantation. However, little data are available on the association between proteinuria and graft/patient survival in the paediatric transplant population. The primary aim of this study was to investigate the associations between posttransplant proteinuria and graft/patient survival in children after renal transplantation. In this retrospective study, we screened all 91 children receiving renal allografts at a single institution between 1997 and 2007. The inclusion criteria were a functioning graft at 1 year posttransplant, data availability and no recurrence of focal-segmental glomerulosclerosis. The final cohort included 75 patients. Proteinuria was considered to be pathologic if the urinary protein/creatinine ratio was >30 mg/mmol. Donor and recipient characteristics, data on proteinuria, estimated glomerular filtration rate (eGFR) and rejection episodes were analysed. The most recent of the biopsies performed during the follow-up after 1 year posttransplant were analysed separately in the proteinuric group and the non-proteinuric group. Proteinuria at 1-year posttransplant was pathologic in 35 % of patients. The 5-year graft survival rate was significantly lower in the proteinuric group than in the non-proteinuric group (77 vs. 100 %; p Proteinuria at 1 year posttransplant was associated with reduced long-term graft survival independent of other risk factors, including decreased eGFR or episodes of acute corticosensitive and corticoresistant rejection. The most frequent histologic finding in the proteinuric group was chronic rejection. There was no significant difference in the 5-year patient survival rate between the proteinuric group and the non-proteinuric group. This study emphasizes the importance of proteinuria as a prognostic factor of renal allograft survival in children.

    The ability of physically restrained and anesthetized wolves to thermoregulate is lessened and could lead to reduced survival, yet no information is available about this subject. Therefore, we analyzed rectal temperatures related to survival 1 year post-capture from 173 adult (non-pup) gray wolves (Canis lupus) captured in modified foot-hold traps for radiocollaring during June–August, 1988–2011, in the Superior National Forest of northeastern Minnesota, USA. The maximum observed rectal temperature (“maxtemp,” ° F, ° C) in each wolf during capture (x = 104.0, 40.0; SD = 2.0, 1.1; min. = 95.9, 35.5; max. = 108, 42.2) was not a significant predictor of survival to 1 year post-capture. Although no weather or morphometric variable was a significant predictor of maxtemps, wolves initially anesthetized with ketamine–xylazine rather than telazol®–xylazine averaged higher maxtemps. This information does not fully address possible effects of high body temperatures related to live-capture and handling of wolves, but it does provide a useful waypoint for future assessments of this relationship and a reassurance to wildlife practitioners that the maxtemps observed in our study did not appear to affect 1-year survival.

    Home tracheotomy mechanical ventilation (HTMV) can prolong survival in patients with amyotrophic lateral sclerosis (ALS) when non-invasive ventilation (NIV) fails, but knowledge about HTMV is scarce. The aim of this study was to determine the causes of tracheotomy and the main issues of 1-year HTMV in a cohort of patients with ALS. A prospective study of all patients needing HTMV was performed in a referral respiratory care unit (RCU) from April 2001 to January 2010. Patients' informed decisions about HTMV were fully respected. Caregivers were trained and could telephone the RCU. Hospital staff made home visits. All patients (n=116) agreed to participate and a tracheotomy was needed for 76, mainly due to bulbar dysfunction. Of the 38 who had a tracheotomy, in 21 it was performed in an acute setting and in 17 as a non-emergency procedure. In 19 patients the tracheotomy was related to the inadequacy of mechanically assisted coughing (MAC) to maintain normal oxygen saturation. During HTMV, 19 patients required hospitalisation, 12 with respiratory problems. The 1-year survival rate was 78.9%, with a mean survival of 10.39 months (95% CI 9.36 to 11.43). Sudden death was the main cause of death (n=9) and only one patient died from respiratory causes. No predictive factors for survival were found. Besides NIV inadequacy, the ineffectiveness of mechanically assisted coughing appears to be a relevant cause of tracheotomy for patients with ALS with severe bulbar dysfunction. Patients choosing HTMV provided by a referral RCU could have a good 1-year survival rate, respiratory problems being the main cause of hospitalisation but not of death.

    Objective The purpose of this study is to describe and discuss laboratory tests ordered on elite athletes in an interdisciplinary sports medicine clinic by a doctor of chiropractic over 1 calendar year. Methods A retrospective review of laboratory tests ordered during routine clinical practice as standard screening and diagnostic tests from November 1, 2009, to November 1, 2010 was performed. Data were collected during clinical encounters at one sports medicine clinic and entered into a database for analysis. Descriptive and frequency statistics were used to describe the tests ordered and the frequency of abnormal findings. Results Five hundred and thirty-nine studies were ordered for diagnostic and routine screenings on 137 athlete patients (86 males, 51 females), representing 49 types of tests. Sample sources included blood, urine, skin lesions, and fecal matter. The most commonly ordered tests were complete blood count, comprehensive metabolic panel, serum ferritin, creatine kinase, serum iron and total iron binding capacity, total cortisol, thyroid stimulating hormone, and lipid panels. There were 217 studies (40%) flagged as abnormal by the reporting laboratory. Conclusion This report provides greater insight into the diverse array of laboratory studies ordered over a 1-year period for diagnosis and screening of elite athletes. A high percentage of the results were flagged as abnormal by the laboratory. These findings show that the unique physiology of the elite athlete must be considered when interpreting laboratory findings in this population. PMID:26257590

    -effective model of secondary prevention to reduce cardiovascular events. There is evidence about the association between psychological distress and both unhealthy behaviour and cardiac course. Depression and psychosomatic distress, such as type A behaviour and demoralization, are frequently associated with CVD course. However, the role of psychiatric and psychosomatic distress in CR is not well known. What does this study add? CR exerted a protective effect on physical activity and a positive effect on eating behaviour, stress management, and quality of sleep. CR did not show any particular effect on smoking, overweight/obesity, dietary habits, medication adherence, and patients' 1-year survival. Findings from this study suggest the importance to consider specific psychological and psychosomatic aspects in affecting lifestyle. © 2016 The British Psychological Society.

    The purpose of this study is to measure the effect of long-term administration of inhaled fluticasone proprionate on cortisol concentrations in heaves-affected horses. Eleven horses with heaves were treated with fluticasone at least once daily at dosages required to improve lung function or with antigen avoidance alone for 1 year. Morning serum cortisol was measured before and after 10, 30, 110, 190, 230, 280, and 320 days of treatment. Cortisol was also measured in the afternoon of day 330. Cortisol was significantly lower in the Fluticasone group on days 30, 110, and 190 when compared with the Antigen avoidance group. Cortisol measured on day 330 was also significantly lower in the Fluticasone group. Results indicate that inhaled fluticasone, when administered at therapeutic dosages, can significantly suppress serum cortisol concentrations for 8-24 h. The clinical significance of this finding remains to be ascertained, as no clinical signs were associated with this cortisol suppression. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Continuous spectral EEG activity monitoring has been used in adults as a monitor of brain activity during anesthesia. It has not been used in infants. We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants.

    Extremity sarcoma has a preponderance to present late with advanced stage at diagnosis. It is important to know why these patients die early from sarcoma and to predict those at high risk. Currently we have mid- to long-term outcome data on which to counsel patients and support treatment decisions, but in contrast to other cancer groups, very little on short-term mortality. Bayesian belief network modeling has been used to develop decision-support tools in various oncologic diagnoses, but to our knowledge, this approach has not been applied to patients with extremity sarcoma. We sought to (1) determine whether a Bayesian belief network could be used to estimate the likelihood of 1-year mortality using receiver operator characteristic analysis; (2) describe the hierarchal relationships between prognostic and outcome variables; and (3) determine whether the model was suitable for clinical use using decision curve analysis. We considered all patients treated for primary bone sarcoma between 1970 and 2012, and excluded secondary metastasis, presentation with local recurrence, and benign tumors. The institution's database yielded 3499 patients, of which six (0.2%) were excluded. Data extracted for analysis focused on patient demographics (age, sex), tumor characteristics at diagnosis (size, metastasis, pathologic fracture), survival, and cause of death. A Bayesian belief network generated conditional probabilities of variables and survival outcome at 1 year. A lift analysis determined the hierarchal relationship of variables. Internal validation of 699 test patients (20% dataset) determined model accuracy. Decision curve analysis was performed comparing net benefit (capped at 85.5%) for all threshold probabilities (survival output from model). We successfully generated a Bayesian belief network with five first-degree associates and describe their conditional relationship with survival after the diagnosis of primary bone sarcoma. On internal validation, the resultant

    ABSTRACT Cystic fibrosis (CF) lung microbiota composition has recently been redefined by the application of next-generation sequencing (NGS) tools, identifying, among others, previously undescribed anaerobic and uncultivable bacteria. In the present study, we monitored the fluctuations of this ecosystem in 15 CF patients during a 1-year follow-up period, describing for the first time, as far as we know, the presence of predator bacteria in the CF lung microbiome. In addition, a new computational model was developed to ascertain the hypothetical ecological repercussions of a prey-predator interaction in CF lung microbial communities. Fifteen adult CF patients, stratified according to their pulmonary function into mild (n = 5), moderate (n = 9), and severe (n = 1) disease, were recruited at the CF unit of the Ramón y Cajal University Hospital (Madrid, Spain). Each patient contributed three or four induced sputum samples during a 1-year follow-up period. Lung microbiota composition was determined by both cultivation and NGS techniques and was compared with the patients’ clinical variables. Results revealed a particular microbiota composition for each patient that was maintained during the study period, although some fluctuations were detected without any clinical correlation. For the first time, Bdellovibrio and Vampirovibrio predator bacteria were shown in CF lung microbiota and reduced-genome bacterial parasites of the phylum Parcubacteria were also consistently detected. The newly designed computational model allows us to hypothesize that inoculation of predators into the pulmonary microbiome might contribute to the control of chronic colonization by CF pathogens in early colonization stages.

    Carotid endarterectomy (CEA) has been shown to be an effective treatment for patients with asymptomatic carotid artery stenosis when perioperative stroke rates are low and patients survive long enough to benefit from the intervention. Our objective was to develop and to validate a simple risk prediction model for 30-day stroke and 1-year mortality to guide optimal selection of patients for CEA. Asymptomatic patients undergoing first-time elective CEA within the Vascular Quality Initiative (VQI) from 2010 to 2015 were selected. Outcome measures included any 30-day postoperative stroke and 1-year mortality. Patient demographics, comorbidities, carotid artery disease burden, and provider characteristics were evaluated to select a parsimonious clinical model for risk prediction using multivariable logistic regression. Internal validation was performed for stroke and split sample validation was done for 1-year survival to ensure generalizability. We identified 31,939 patients for inclusion in the stroke analysis (2010-2015) and 24,086 patients for the mortality analysis (2010-2014). Both the 30-day stroke rate (0.9%) and 1-year mortality rate (3.4%) varied substantially across 265 VQI centers (range, 0%-8.3% and 0%-20%, respectively). Eleven significant factors were selected for the 30-day stroke risk prediction model (area under the receiver operating characteristic curve [AUC], 0.67). Internal validation demonstrated good discrimination (bias corrected AUC = 0.652; calibration intercept and slope of 0.03 and 1.01, respectively). Similarly, 10 significant factors were selected for the 1-year mortality risk prediction model (AUC, 0.764). External validation demonstrated excellent discrimination and calibration (AUC, 0.764; 95% confidence interval, 0.72-0.80). Stroke and 1-year mortality rates after CEA for asymptomatic stenosis vary across VQI centers. We have developed a preoperative risk model that can be used to accurately estimate risk of perioperative stroke and 1

    Full Text Available OBJECTIVE: This study aimed to assess the survival and life quality evolution of patients subjected to surgical excision of oral and oropharyngeal squamous cell carcinoma. MATERIAL AND METHODS: Forty-seven patients treated at a Brazilian healthcare unit specialized in head and neck surgery between 2006 and 2007 were enrolled in the study. The gathering of data comprised reviewing hospital files and applying the University of Washington Quality of Life (UW-QOL questionnaire previously and 1 year after the surgery. Comparative analysis used Poisson regression to assess factors associated with survival and a paired t-test to compare preoperative and 1-year postoperative QOL ratings. RESULTS: 1 year after surgery, 7 patients were not found (dropout of the cohort; 15 had died and 25 fulfilled the UW-QOL again. The risk of death was associated with having regional metastasis previously to surgery (relative risk=2.18; 95% confidence interval=1.09-5.17 and tumor size T3 or T4 (RR=2.30; 95%CI=1.05-5.04. Survivors presented significantly (p<0.05 poorer overall and domain-specific ratings of quality of life. Chewing presented the largest reduction: from 74.0 before surgery to 34.0 one year later. Anxiety was the only domain whose average rating increased (from 36.0 to 70.7. CONCLUSIONS: The prospective assessment of survival and quality of life may contribute to anticipate interventions aimed at reducing the incidence of functional limitations in patients with oral and oropharyngeal cancer.

    Intrasubstance meniscal signal changes not reaching the articular surface on fast spin echo (FSE) sequences are considered to represent mucoid degeneration on MRI. The aim of this study was to evaluate the association of prevalent intrasubstance signal changes with incident tears of the medial meniscus detected on 3.0 T MRI over a 1-year period. A total of 161 women aged {>=}40 years participated in a longitudinal 1-year observational study of knee osteoarthritis. MRI (3.0 T) was performed at baseline and 12-month follow-up. The anterior horn, body, and posterior horn of the medial meniscus were scored by two experienced musculoskeletal radiologists using the Boston-Leeds Osteoarthritis Knee Score (BLOKS) system. Four grades were used to describe the meniscal morphology: grade 0 (normal), grade 1 (intrasubstance signal changes not reaching the articular surface), grade 2 (single tears), and grade 3 (complex tears and maceration). Fisher's exact test and the Cochran-Armitage trend test were performed to evaluate whether baseline intrasubstance signal changes (grade 1) predict incident meniscal tears/maceration (grades 2 and/or 3) in the same subregion of the medial meniscus, when compared to subregions without pathology as the reference group (grade 0). Medial meniscal intrasubstance signal changes at baseline did not predict tears at follow-up when evaluating the anterior and posterior horns (left-sided p-values 0.06 and 0.59, respectively). No incident tears were detected in the body. We could not demonstrate an association between prevalent medial meniscal intrasubstance signal changes with incident tears over a 1-year period. (orig.)

    2017-04-01

    Systematic review OBJECTIVE.: The aim of the study was to investigate whether magnetic resonance imaging (MRI) findings change over a relatively short period of time (sciatica. We also investigated whether there was an association between any change in MRI findings and change in clinical outcomes. MRI offers the potential to identify possible pathoanatomic sources of LBP and/or sciatica; however, the clinical importance of MRI findings remains unclear. Little is known about whether lumbar MRI findings change over the short term and if so whether these changes are associated with changes in clinical outcomes. Medline, EMBASE, and CINAHL databases were searched. Included were cohort studies that performed repeat MRI scans within 12 months in patients with LBP and/or sciatica. Data on study characteristics and change in MRI findings were extracted from included studies. Any data describing associations between change in MRI findings and change in clinical outcomes were also extracted. A total of 12 studies met the inclusion criteria and were included in the review. Pooling was not possible due to heterogeneity of studies and findings. Seven studies reported on changes in disc herniation and reported 15% to 93% of herniations reduced or disappeared in size. Two studies reported on changes in nerve root compression and reported 17% to 91% reduced or disappeared. Only one study reported on the association between change in MRI findings and change in clinical outcomes within 1 year, and found no association. This review found moderate evidence that the natural course of herniations and nerve root compression is favorable over a 1-year period in people with sciatica or LBP. There is a lack of evidence on whether other MRI findings change, and whether changes in MRI findings are associated with changes in clinical outcomes. 1.

    This paper is a contribution to a better understanding of the tsunamigenic potential of large submarine earthquakes. Here, we analyze the tsunamigenic potential of large earthquakes which have occurred worldwide with magnitudes around Mw = 7.0 and greater during a period of 1 year, from June 2013 to June 2014. The analysis involves earthquake model evaluation, tsunami numerical modeling, and sensors' records analysis in order to confirm the generation of a tsunami (or lack thereof) following the occurrence of an earthquake. We also investigate and discuss the sensitivity of tsunami generation to the earthquake parameters recognized to control tsunami occurrence, including the earthquake location, magnitude, focal mechanism and fault rupture depth. Through this analysis, we attempt to understand why some earthquakes trigger tsunamis and others do not, and how the earthquake source parameters are related to the potential of tsunami generation. We further discuss the performance of tsunami warning systems in detecting tsunamis and disseminating the alerts. A total of 23 events, with magnitudes ranging from Mw = 6.7 to Mw = 8.1, have been analyzed. This study shows that about 39 % of the analyzed earthquakes caused tsunamis that were recorded by different sensors with wave amplitudes varying from a few centimeters to about 2 m. Tsunami numerical modeling shows good agreement between simulated waveforms and recorded waveforms, for some events. On the other hand, simulations of tsunami generation predict that some of the events, considered as non-tsunamigenic, caused small tsunamis. We find that most generated tsunamis were caused by shallow earthquakes (depth < 30 km) and thrust faults that took place on/near the subduction zones. The results of this study can help the development of modified and improved versions of tsunami decision matrixes for various oceanic domains.

    The ATHENA study expanded on the safety and efficacy data derived from first-line trials of bevacizumab combined with standard chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC). In ATHENA, 2,264 patients received first-line bevacizumab-containing therapy in routine oncology practice. Overall survival (OS) data are now mature; additional analyses from this large data set can provide insights into treatment duration and the effect of prolonged bevacizumab exposure, where data are currently limited. Patients with HER2-negative LR/mBC received first-line bevacizumab with standard chemotherapy until disease progression, unacceptable toxicity, or physician/patient decision. We performed subgroup analyses on data from patients treated for ≥12 months and those who continued single-agent bevacizumab after stopping chemotherapy. After median follow-up of 20.1 months, median OS was 25.2 months (95% confidence interval [CI] 24.0-26.3 months) in the entire population. Median OS was 30.0 months (95% CI 28.5-32.7 months) in 1,205 patients who continued bevacizumab after discontinuation of chemotherapy and 18.4 months (95% CI 17.2-19.7 months) in 1,058 patients who discontinued bevacizumab before or at the same time as stopping chemotherapy. Bevacizumab treatment was continued for ≥12 months in 473 patients (21%). In most, bevacizumab was administered as monotherapy for extended periods after stopping chemotherapy. In the subgroup of patients treated for ≥12 months, the median time to onset of grade 3-5 adverse events was 5.0 months. There was no evidence that first onset of adverse events of special interest, except for proteinuria, was more common in later than earlier cycles. No relationship was detected between development of hypertension and OS. Findings from these analyses suggest that patients with LR/mBC can receive bevacizumab for prolonged periods without major toxicity or progression of disease. In the absence of progression, continuation of

    Women have lower mortality at all ages and a survival advantage with respect to most causes of death, including acute life-threatening events. We assume the sex differences in survival to be larger after the onset of an acute health condition. Using a 5% random sample of the Danish population, we...... compare the absolute sex differences in 1-year survival after the first hospital admission at age 50+ with the differentials in the corresponding general and never-hospitalized population at age 50—69 during the years 1977—2011 in Denmark. We find the male excess mortality after an admission to hospital...

    Monitoring of progress in cancer patient survival by cancer registries should be as up-to-date as possible. Period analysis has been shown to provide more up-to-date survival estimates than do traditional methods of survival analysis. However, there is a trade-off between up-to-dateness and the precision of period estimates, in that increasing the up-to-dateness of survival estimates by restricting the analysis to a relatively short, recent time period, such as the most recent calendar year for which cancer registry data are available, goes along with a loss of precision. The authors propose a model-based approach to maximize the up-to-dateness of period estimates at minimal loss of precision. The approach is illustrated for monitoring of 5-year relative survival of patients diagnosed with one of 20 common forms of cancer in Finland between 1953 and 2002 by use of data from the nationwide Finnish Cancer Registry. It is shown that the model-based approach provides survival estimates that are as up-to-date as the most up-to-date conventional period estimates and at the same time much more precise than the latter. The modeling approach may further enhance the use of period analysis for deriving up-to-date cancer survival rates.

    We sampled the surface waters (2-50 m) of two deep peri-alpine lakes over a 1-year period in order to examine (1) the abundance, vertical distribution, genome size, and morphology structures of the virioplankton; (2) the virus-mediated bacterial mortality; and (3) the specific genome size range of double-stranded DNA (dsDNA) phytoplankton viruses. Virus-like particle (VLP) concentrations varied between 4.16 × 10(7) (January) and 2.08 × 10(8) part mL(-1) (May) in Lake Bourget and between 2.7 × 10(7) (June) and 8.39 × 10(7) part mL(-1) (November) in Lake Annecy. Our flow cytometry analysis revealed at least three viral groups (referred to as virus-like particles 1, 2, and 3) that exhibited distinctive dynamics suggestive of different host types. Phage-induced bacterial mortality varied between 6.1% (June) and 33.2% (October) in Lake Bourget and between 7.4% (June) and 52.6% (November) in Lake Annecy, suggesting that viral lysis may be a key cause of mortality of the bacterioplankton. Virioplankton genome size ranged from 27 to 486 kb in Lake Bourget, while it reached 620 kb in Lake Annecy for which larger genome sizes were recorded. Our analysis of pulsed field gel electrophoresis bands using different PCR primers targeting both cyanophages and algal viruses showed that (1) dsDNA viruses infecting phytoplankton may range from 65 to 486 kb, and (2) both cyanophage and algal "diversity" were higher in Lake Annecy. Lakes Annecy and Bourget also differed regarding the proportions of both viral families (with the dominance of myoviruses vs. podoviruses) and infected bacterial morphotypes (short rods vs. elongated rods), in each of these lakes, respectively. Overall, our results reveal that (1) viruses displayed distinct temporal and vertical distribution, dynamics, community structure in terms of genome size and morphology, and viral activity in the two lakes; (2) the Myoviridae seemed to be the main cause of bacterial mortality in both lakes and this

    Giant cell glioblastomas are defined as glioblastomas with a marked predominance of bizarre, multinucleated giant cells. They represent about 5% of all glioblastomas and can occur at any site of the central nervous system, but the temporal and frontal lobes are the sites of predilection. Overall, giant cell glioblastomas show a prolonged survival period compared with common glioblastoma multiforme, and survival periods of 7 and 9 years have been reported in adults. Here we report on a child aged 11 years at diagnosis, who has so far survived for 11 years since operation and adjunctive radio- and chemotherapy.

    Full Text Available Background: Neuroblastoma is a malignant tumor of the sympathetic nervous system, representning about 5 % of all childhood malignancies. The aim of our study was to compare the survival of neuroblastoma patients treated in Slovenia in two time periods, 1994–2007 and 1980–1993, and analyze the influence of different factors on survival. The hypothesis was that there has been an improvement in the survival of neuroblastoma patients treated after 1994.Methods: Seventy-eight neuroblastoma patients, treated at the Department of Pediatrics and at the Institute of Oncology in Ljubljana in the period 1980–2007 were included in the retrospective study. The list of patients and their basic data were collected from the Cancer Registry of Slovenia. Furtjer data about the patients, tumor characteristics and treatment were collected from patients’ records.Results: Thirty-nine (50 % out of seventy-eight neuroblastoma patients included in the study are alive; of the 39 (50 % dead, 23 (29.5 % died during primary tumor treatment, 15 (19.2 % died after recurrent disease, and the cause of death in one (1.3 % patient remained unknown. The survival rates according to stage of disease, site of primary tumor and tumor size have improved in children treated after 1994, as compared to those treated before 1994. The most important factors influencing the prognosis in both time periods were stage of disease, patients’ age and tumor size at diagnosis while there was no statistical difference in survival according to age at diagnosis and the extent of surgery.Conclusions: The retrospective study confirmed our hypothesis that the survival of our patients treated after 1994 was better than the survival of those treated before. The most important prognostic factors in both periods were stage of the disease, age at diagnosis and tumor size.

    1-6 months and 1-12 months treatment periods, respectively, with compliance rates>80% being associated with the majority of the study population reporting at least one AE. Overall, 74.1% and 65.8% of the patients reported at least one AE during the 1-6 months and 1-12 months treatment periods, respectively, compared with 20.4% and 10.8% of patients reporting at least one treatment-related AE during these periods. Disorders of the nervous system and respiratory thoracic and mediastinal system, in particular headache, somnolence and catarrh, were the three most common AEs reported by >5% of the patients during both treatment periods. Detailed ECG assessments demonstrated no clinically relevant abnormal ECG findings, nor any QTcB increases >60 msec or QTcB values>470 msec for any patient at any time during treatment. Serious AEs were reported in seven patients, of whom six were considered as unlikely to be related to rupatadine treatment, whereas one involving increased blood enzyme levels was considered as possibly related to rupatadine treatment. This study confirmed the good long-term safety and tolerability of rupatadine at the therapeutic dose of 10 mg/day in patients with PER.

  11. Periodic lateralized epileptiform discharges can survive anesthesia and result in asymmetric drug-induced burst suppression

    2017-02-01

    Full Text Available Drug-induced burst suppression (DIBS is bihemispheric and bisymmetric in adults and older children. However, asymmetric DIBS may occur if a pathological process is affecting one hemisphere only or both hemispheres disproportionately. The usual suspect is a destructive lesion; an irritative or epileptogenic lesion is usually not invoked to explain DIBS asymmetry. We report the case of a 66-year-old woman with new-onset seizures who was found to have a hemorrhagic cavernoma and periodic lateralized epileptiform discharges (PLEDs in the right temporal region. After levetiracetam and before anesthetic antiepileptic drugs (AEDs were administered, the electroencephalogram (EEG showed continuous PLEDs over the right hemisphere with maximum voltage in the posterior temporal region. Focal electrographic seizures also occurred occasionally in the same location. Propofol resulted in bihemispheric, but not in bisymmetric, DIBS. Remnants or fragments of PLEDs that survived anesthesia increased the amplitude and complexity of the bursts in the right hemisphere leading to asymmetric DIBS. Phenytoin, lacosamide, ketamine, midazolam, and topiramate were administered at various times in the course of EEG monitoring, resulting in suppression of seizures but not of PLEDs. Ketamine and midazolam reduced the rate, amplitude, and complexity of PLEDs but only after producing substantial attenuation of all burst components. When all anesthetics were discontinued, the EEG reverted to the original preanesthesia pattern with continuous non-fragmented PLEDs. The fact that PLEDs can survive anesthesia and affect DIBS symmetry is a testament to the robustness of the neurodynamic processes underlying PLEDs.

    The use of endosseous dental implants has become common practice for the rehabilitation of edentulous patients, and a two-implant overdenture has been recommended as the standard of care. The use of small-diameter implants may extend treatment options and reduce the necessity for bone augmentation. However, the mechanical strength of titanium is limited, so titanium alloys with greater tensile and fatigue strength may be preferable. This randomized, controlled, double-blind, multicenter study investigated in a split-mouth model whether small-diameter implants made from Titanium-13Zirconium alloy (TiZr, Roxolid™) perform at least as well as Titanium Grade IV implants. Patients with an edentulous mandible received one TiZr and one Ti Grade IV small-diameter bone level implant (3.3 mm, SLActive®) in the interforaminal region. The site distribution was randomized and double-blinded. Outcome measures included change in radiological peri-implant bone level from surgery to 12 months post-insertion (primary), implant survival, success, soft tissue conditions, and safety (secondary). Of 91 treated patients, 87 were available for the 12-month follow-up. Peri-implant bone level change (-0.3 ± 0.5 mm vs -0.3 ± 0.6 mm), plaque, and sulcus bleeding indices were not significantly different between TiZr and Ti Grade IV implants. Implant survival rates were 98.9 percent and 97.8 percent, success rates were 96.6 percent and 94.4 percent, respectively. Nineteen minor and no serious adverse events were related to the study devices. This study confirms that TiZr small-diameter bone level implants provide at least the same outcomes after 12 months as Ti Grade IV bone level implants. The improved mechanical properties of TiZr implants may extend implant therapy to more challenging clinical situations. © 2011 Wiley Periodicals, Inc.

    Organisms may survive unfavorable conditions either by moving to more favorable areas by means of dispersal or by adapting to stressful environments. Pleistocene glacial periods represent extremely unfavorable conditions for the majority of life forms, especially sessile organisms. Many studies have revealed placements of refugial areas and postglacial colonization patterns of seed plants, but little is still known about areas of long-term survival and historical migration routes of bryophytes. Given overall differences in stress tolerance between seed plants and bryophytes, it is of interest to know whether bryophytes have survived periods of extreme climatic conditions better then seed plants in northern areas. The haploid and rarely spore-producing peat moss Sphagnum wulfianum is mostly found in areas that were covered by ice during the last glacial maximum. Twelve microsatellite markers were amplified from 43 populations (367 shoots) of this species, and data were analyzed using population genetic diversity statistics, Bayesian clustering methods, and coalescence-based inference tools to estimate historical and demographic parameters. Genetic diversity within populations was low, but populations were highly differentiated, with two main genetic clusters being recognized. The two main genetic groups have diverged quite recently in the Holocene, and the pattern of genetic variability and structuring gives no support for survival in Scandinavian refugia during the last glacial period in this species. The dispersal ability of this plant thus seems surprisingly high despite its infrequent spore production.

    Expert guidelines for treatment of cardiac arrest recommend administration of adrenaline (epinephrine) every three to five minutes. However, the effects of different dosing periods of epinephrine remain unclear. We sought to evaluate the association between epinephrine average dosing period and survival to hospital discharge in adults with an in-hospital cardiac arrest (IHCA). We performed a retrospective review of prospectively collected data on 20,909 IHCA events from 505 hospitals participating in the Get With The Guidelines-Resuscitation (GWTG-R) quality improvement registry. Epinephrine average dosing period was defined as the time between the first epinephrine dose and the resuscitation endpoint, divided by the total number of epinephrine doses received subsequent to the first epinephrine dose. Associations with survival to hospital discharge were assessed by using generalized estimating equations to construct multivariable logistic regression models. Compared to a referent epinephrine average dosing period of 4 to <5 min per dose, survival to hospital discharge was significantly higher in patients with the following epinephrine average dosing periods: for 6 to <7 min/dose, adjusted odds ratio [OR], 1.41 (95%CI: 1.12, 1.78); for 7 to <8 min/dose, adjusted OR, 1.30 (95%CI: 1.02, 1.65); for 8 to <9 min/dose, adjusted OR, 1.79 (95%CI: 1.38, 2.32); for 9 to <10 min/dose, adjusted OR, 2.17 (95%CI: 1.62, 2.92). This pattern was consistent for both shockable and non-shockable cardiac arrest rhythms. Less frequent average epinephrine dosing than recommended by consensus guidelines was associated with improved survival of in-hospital cardiac arrest. Copyright © 2013 Elsevier Ireland Ltd.

    Predicting survival and extinction scenarios for climate change requires an understanding of the present day ecological characteristics of species and future available habitats, but also the adaptive potential of species to cope with environmental change. Hybridization is one mechanism that could facilitate this. Here we report statistical evidence that the transfer of genetic information through hybridization is a feature of species from the plant genus Pachycladon that survived the Last Glacial Maximum in geographically separated alpine refugia in New Zealand's South Island. We show that transferred glucosinolate hydrolysis genes also exhibit evidence of intra-locus recombination. Such gene exchange and recombination has the potential to alter the chemical defence in the offspring of hybridizing species. We use a mathematical model to show that when hybridization increases the adaptive potential of species, future biodiversity will be best protected by preserving closely related species that hybridize rather than by conserving distantly related species that are genetically isolated.

    In studies using patient administrative data, the identification of the first (incident) acute myocardial infarction (AMI) in an individual is based on retrospectively excluding previous hospitalizations for the same condition during a fixed time period (lookback period [LP]). Our aim was to investigate whether the length of the LP used to identify the first AMI had an effect on trends in AMI incidence and subsequent survival in a nationwide study. All AMI events during 1994 to 2009 were retrieved from the Cardiovascular Disease in Norway project. Incident AMIs during 2004 to 2009 were identified using LPs of 10, 8, 7, 5, and 3 years. For each LP, we calculated time trends in incident AMI and subsequent 28-day and 1-year mortality rates. Results obtained from analyses using the LP of 10 years were compared with those obtained using shorter LPs. In men, AMI incidence rates declined by 4.2% during 2004 to 2009 (incidence rate ratio, 0.958; 95% confidence interval, 0.935-0.982). The use of other LPs produced similar results, not significantly different from the LP of 10 years. In women, AMI incidence rates declined by 7.3% (incidence rate ratio, 0.927; 95% confidence interval, 0.901-0.955) when an LP of 10 years was used. The decline was statistically significantly smaller for the LP of 5 years (6.2% versus 7.3%; P=0.02) and 3 years (5.9% versus 7.3%; P=0.03). The choice of LP did not influence trends in 28-day and 1-year mortality rates. The length of LP may influence the observed time trends in incident AMIs. This effect is more evident in older women. © 2015 American Heart Association, Inc.

    Proteinuria is the most important risk factor for IgA nephropathy progression. The purpose of this study is to evaluate the long-term outcome and risk factors for poor prognosis in childhood IgA nephropathy. Patients who were diagnosed with IgA nephropathy between 1972 and 1992 at the Tokyo Metropolitan Kiyose Children's Hospital were included. We analyzed risk factors for progression to end-stage kidney disease (ESKD) and chronic renal insufficiency (CRI) using Kaplan-Meier method and multivariate analyses of Cox proportional hazard model. One hundred patients were included and the median observation period was 11.8 years. Twelve and 17 patients progressed to ESKD and CRI, respectively. The survival probabilities were 90.0% at 10 years and 79.8% at 20 years for ESKD, and 86.1% at 10 years and 72.3% at 20 years for CRI. Notably, patients with heavy proteinuria with hypoalbuminemia during follow-up period showed extremely poor prognosis. In this group, the survival rate at 10 years from ESKD and CRI was 40.6% and 20.8%, respectively. By multivariate analysis, proteinuria at diagnosis and proteinuria during follow-up period were risk factors for ESKD, whereas glomeruli showing mesangial proliferation ≥50% and proteinuria during follow-up period were risk factors for CRI. Patients without heavy proteinuria during follow-up period did not develop CRI and 63% of patients with mild proteinuria during follow-up period showed no proteinuria at the last observation. The degree of proteinuria during follow-up period is the strongest risk factor for ESKD and CRI.

  19. Comparing environmental issues in Cuba before and after the Special Period: balancing sustainable development and survival.

    Following the Earth Summit in 1992, Cuba designed and implemented a variety of programs, administrative structures, and public awareness activities to promote sound environmental management and sustainable development. This came shortly after the fall of the Soviet Union and the strengthening of the US blockade in 1990, which resulted in a 35% drop in Cuban GDP. This period, referred to as the Special Period, witnessed a decrease in many environmentally damaging activities both by choice and by necessity, but also resulted in many decisions to resuscitate the Cuban economy. The purpose of this work was to compare and rank the environmental risks Cuba faced before and during the Special Period (1990-2000) using two Comparative environmental risk assessments (CERAs). To do so, an ecosystem integrity risk assessment matrix was constructed with 42 risk end points. The matrix assessed the risk posed by 17 problem areas including air pollution, water contamination, solid waste sites, pesticides and ecosystem degradation. The risks were calculated using five criteria: area affected, vulnerability of affected population, severity of impact, irreversibility of effect and uncertainty. To construct this matrix, both literature reviews and expert interviews in Cuba were conducted in 2000. The results showed a general decrease in risk scores during the Special Period. Before the Special Period, high risks were posed by: terrestrial degradation and industrial wastewater and sludge, followed by freshwater degradation, surface water stressors, and pesticides. After the Special Period, industrial wastewater and sludge and pesticides were no longer high-risk areas, but municipal wastewater and marine coastal degradation ranked higher than previously. Also, the risk endpoints most stressed after 1990 were affected by activities controlled by the government, such as mining and tourism, and lack of infrastructure. Therefore, the claims that public environmental education is the main

Our study aim was to evaluate the effect of octylphenol on growth and survival of zebra fish, from 21-115 days, and within 21-75 days of life. For this purpose, for each period under study, fishes were divided into three groups of 30 individuals, named: Lot 1 - Control, respectively lots 2 and 3, at which the administrated octylphenol concentrations were of 60 μg L-1, respectively 100 μg L-1. Fishes of the six groups were raised in 30-liters aquariums (30 fish / aquarium. The growth was measured by weighing and biometric measurements (total length, standard length, the length of the head, maximal height, minimal height and the mass of the body, while the surviving rate was established at the end of every period and at the end of the experiment, when we were able to calculate the total number of dead fish. Biometric study of the analysis performed in 75 days, 115 days respectively shows that octylphenol has negative influence on body development, and survival both, the highest percentage of mortality (46,66% was registered at 100 μgL-1 concentration, between 21 -75 days.

    Prostate cancer is the most common cancer among men in many countries. The aim of the present study was to find out how the symptoms leading to a diagnosis, diagnostic procedures and stages of the disease among prostate cancer patients have changed over a period of 20 years. This retrospective chart review consisted of 421 prostate cancer patients whose treatment was started in the years 1982, 1987, 1992, 1997 and 2002 at the Oulu University Hospital. Earlier prostatic disorders, specific urological symptoms, diagnostic procedures, the TNM classification and histological grade were recorded. The number of symptom-free prostate cancer patients increased over the 20 years, as did the number of men suffering from chronic prostatitis, although the latter increase was not statistically significant. A drop in the number of clinical T4 cases and increase of clinical T1 and clinical T2 cases was recorded but no clear change in the histological distribution occurred. The 5-year prostate cancer-specific survival improved significantly over the 20 years. The urologist was found to be the person who was contacted first most often. Our data indicate that the number of prostate cancer patients has increased hugely over the period from 1982 to 2002 and although the clinical T stage has moved towards earlier stages, the proportion of well differentiated cancers remains low, so that most patients have clinically significant cancer with the need of some form of therapy. Further, prostate cancer-specific survival improved significantly over the period.

    In the frame of the Cox proportional hazard (PH) model, a novel two-step procedure for estimating age-period-cohort (APC) effects on the hazard function of death from cancer was developed. In the first step, the procedure estimates the influence of joint APC effects on the hazard function, using Cox PH regression procedures from a standard software package. In the second step, the coefficients for age at diagnosis, time period and birth cohort effects are estimated. To solve the identifiability problem that arises in estimating these coefficients, an assumption that neighboring birth cohorts almost equally affect the hazard function was utilized. Using an anchoring technique, simple procedures for obtaining estimates of interrelated age at diagnosis, time period and birth cohort effect coefficients were developed.As a proof-of-concept these procedures were used to analyze survival data, collected in the SEER database, on white men and women diagnosed with LC in 1975-1999 and the age at diagnosis, time period and birth cohort effect coefficients were estimated. The PH assumption was evaluated by a graphical approach using log-log plots. Analysis of trends of these coefficients suggests that the hazard of death from LC for a given time from cancer diagnosis: (i) decreases between 1975 and 1999; (ii) increases with increasing the age at diagnosis; and (iii) depends upon birth cohort effects.The proposed computing procedure can be used for estimating joint APC effects, as well as interrelated age at diagnosis, time period and birth cohort effects in survival analysis of different types of cancer.

    A national surveillance programme for Salmonella Dublin, based on regular bulk-tank milk antibody screening and movements of cattle, was initiated in Denmark in 2002. From 2002 to end of 2009 the prevalence of test-positive dairy herds was reduced from 26% to 10%. However, new infections and spread......-quarters (YQs), either at the start of the study period or after recovery from infection. Survival analysis was performed on a dataset including 6931 dairy herds with 118969 YQs at risk, in which 1523 failures (new infection events) occurred. Predictors obtained from register data were tested in a multivariable...

    The study of biotropic effects of modern space weather carries the information about the rhythms and features of adaptation of early biological systems to the outer space influence. The influence of cosmic rays, ultraviolet waves and geomagnetic field on early life has its signs in modern biosphere processes. These phenomena could be experimentally studied on present-day biological objects. Particularly inorganic polyphosphates, so-called "fossil molecules", attracts special attention as the most ancient molecules which arose in inanimate nature and have been accompanying biological objects at all stages of evolution. Polyphosphates-containing graves of yeast's cells of Saccharomyces cerevisiae strain Y-517, , from the Ukrainian Collection of Microorganisms was studied by daily measurements during 2000-2013 years. The IZMIRAN daily data base of physiological parameters dynamics during 2000-2013 years were analyzed simultaneously (25 people). The analysis showed significant simultaneous changes of the statistical parameters of the studied biological systems in 2004 -2006. The similarity of simultaneous changes of adaptation strategies of human organism and the cell structures of Saccharomyces cerevisiae during the 23-24 cycles of solar activity are discussed. This phenomenon could be due to a replacement of bio-effective parameters of space weather during the change from 23rd to 24th solar activity cycle and nonstandard geophysical peculiarities of the 24th solar activity cycle. It could be suggested that the observed similarity arose as the optimization of evolution selection of the living systems in expectation of probable prolonged period of low solar activity (4-6 cycles of solar activity).

    Most kelps (order Laminariales) exhibit distinct temporal patterns in zoospore production, gametogenesis and gametophyte reproduction. Natural fluctuations in ambient environmental conditions influence the intrinsic characteristics of gametes, which define their ability to tolerate varied conditions. The aim of this work was to document seasonal patterns in reproduction and gametophyte growth and survival of Ecklonia radiata (C. Agardh) J. Agardh in south-western Australia. These results were related to patterns in local environmental conditions in an attempt to ascertain which factors explain variation throughout the season. E. radiata was fertile (produced zoospores) for three and a half months over summer and autumn. Every two weeks during this time, gametophytes were grown in a range of temperatures (16-22 °C) in the laboratory. Zoospore densities were highly variable among sample periods; however, zoospores released early in the season produced gametophytes which had greater rates of growth and survival, and these rates declined towards the end of the reproductive season. Growth rates of gametophytes were positively related to day length, with the fastest growing recruits released when the days were longest. Gametophytes consistently survived best in the lowest temperature (16 °C), yet exhibited optimum growth in higher culture temperatures (20-22 °C). These results suggest that E. radiata releases gametes when conditions are favourable for growth, and E. radiata gametophytes are tolerant of the range of temperatures observed at this location. E. radiata releases the healthiest gametophytes when day length and temperature conditions are optimal for better germination, growth, and sporophyte production, perhaps as a mechanism to help compete against other species for space and other resources.

    Optimizing immunosuppressive treatment in the early posttransplant period is important for achieving long-term graft function and survival. There were 205 renal transplant recipients involved in this study. Patients were divided into groups according to the induction therapy (no induction vs basiliximab/daclizumab vs rabbit antithymocyte globulin), maintenance therapy at the time of transplantation (tacrolimus [TAC] vs cyclosporine), the average trough TAC levels in months 4 to 6 after TO and serum creatinine 5 years after renal transplantation. The incidence of acute rejection was significantly higher in cyclosporine than in TAC group of patients (P = .0364). The average TAC levels on elapsed time after transplantation significantly decreased (P < .0001). Five years after renal transplantation, there were higher TAC levels (5.6 ± 0.7 ng/mL) in the group with "zero" low levels than in the group with "zero" high levels (4.6 ± 1.1 ng/mL), which was statistically significant (P < .0001). We did not find any difference in graft and patient survival in posttransplant years 2 to 5 according to TAC levels or the induction treatment. In our study, we have confirmed that better graft function 5 years after transplantation was connected with higher trough tacrolimus levels on elapsed time after renal transplantation.

    Full Text Available Background & objectives: In India, diurnally sub periodic Wuchereria bancrofti transmitted by Downsiomyia nivea is prevalent only in the Nicobar district of Andaman and Nicobar Islands. The ongoing LF elimination programme aims at transmission interruption by bringing down the microfilarie (mf load in the community, which has implication on the parasite load in mosquito vector. Therefore, understanding density dependent constraints on transmission assumes significance from control perspective. The present study was undertaken in Teressa Island to understand the density dependent parasite mortality and survival probability of the parasite Do. nivea. Methods: The entomological data collected from Teressa Island, endemic for the diurnally sub periodic form of W. bancrofti were used to examine the parasite loss and its survival up to infectivity. Patterns of parasite distribution in Do. nivea were examined. Results: Distribution patterns of microfilariae were found to be over dispersed in Do. nivea. The later stages of the parasite in the vector were randomly distributed. Distribution pattern of various filarial larval stages suggested that the loss of parasites occurred as development progressed and was maximal between the first and second stages. Further, both the prevalence of infection and the degree of parasite aggregation in the vector population have fallen significantly with development of parasite stage. Interpretation & conclusions: Results indicate the operation of parasite density dependent mortality of vectors or parasite loss or combination of both. The present study with Aedes transmitted filariasis conducted before launching LF elimination programme in the study area indicates a comparable level of parasite regulation in the vector which has similar implications on the transmission threshold. Thus, the consideration of Aedes with Culex in deriving the critical level of antigen positive for making decisions on cessation of mass drug

    Full Text Available Abstract Background Population-based studies on endometrial cancer providing survival estimates by age, histology, and stage have been sparse. We aimed to derive most up-to-date and detailed survival estimates for endometrial cancer patients in Germany. Methods We used a pooled German national dataset including data from 11 cancer registries covering a population of 33 million people. 30,906 patients diagnosed with endometrial cancer in 1997-2006 were included. Period analysis was performed to calculate 5-year relative survival (RS in 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age-adjustment was performed using five age groups (15-44, 45-54, 55-64, 65-74, and 75+ years. Results Overall, age-adjusted 5-year relative survival in 2002-2006 was 81%. A moderate age gradient was observed, with 5-year RS decreasing from 90% in the age group 15-49 years to 75% in the age group 70+ years. Furthermore prognosis varied strongly by histologic subtypes and stage, with age-adjusted 5-year RS ranging from 43% (for sarcoma to 94% (for squamous metaplasia, and reaching 91% for localized, 51% for regional, and 20% for distant stage. Except for age group 65-74 years, no significant improvement in survival was seen during the recent 5-year period under investigation. Conclusion In this comprehensive population-based survival analysis of patients with endometrial cancer from Germany, prognosis of endometrial cancer moderately varied by age, and strongly varied by histology and stage. While prognosis is rather good overall, further improvement in 5-year relative survival of endometrial cancer patients has been stagnating in the early 21st century.

    BACKGROUND: The effect of bystander interventions on long-term functional outcomes among survivors of out-of-hospital cardiac arrest has not been extensively studied. METHODS: We linked nationwide data on out-of-hospital cardiac arrests in Denmark to functional outcome data and reported the 1-year...... risks of anoxic brain damage or nursing home admission and of death from any cause among patients who survived to day 30 after an out-of-hospital cardiac arrest. We analyzed risks according to whether bystander cardiopulmonary resuscitation (CPR) or defibrillation was performed and evaluated temporal...... changes in bystander interventions and outcomes. RESULTS: Among the 2855 patients who were 30-day survivors of an out-of-hospital cardiac arrest during the period from 2001 through 2012, a total of 10.5% had brain damage or were admitted to a nursing home and 9.7% died during the 1-year follow-up period...

    Although previous studies suggest similar patient survival for peritoneal dialysis (PD) and haemodialysis (HD), PD use has decreased worldwide. We aimed to study trends in the choice of first dialysis modality and relate these to variation in patient and technique survival and kidney transplant rates in Europe over the last 20 years. We used data from 196 076 patients within the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry who started renal replacement therapy (RRT) between 1993 and 2012. Trends in the incidence rate and prevalence on Day 91 after commencing RRT were quantified with Joinpoint regression. Crude and adjusted hazard ratios (HRs) for 5-year dialysis patient and technique survival were calculated using Cox regression. Analyses were repeated using propensity score matching to control for confounding by indication. PD prevalence dropped since 2007 and HD prevalence stabilized since 2009. Incidence rates of PD and HD decreased from 2000 and 2009, respectively, while the incidence of kidney transplantation increased from 1993 onwards. Similar 5-year patient survival for PD versus HD patients was found in 1993-97 [adjusted HR: 1.02, 95% confidence interval (95% CI): 0.98-1.06], while survival was higher for PD patients in 2003-07 (HR: 0.91, 95% CI: 0.88-0.95). Both PD (HR: 0.95, 95% CI: 0.91-1.00) and HD technique survival (HR: 0.93, 95% CI: 0.87-0.99) improved in 2003-07 compared with 1993-97. Although initiating RRT on PD was associated with favourable patient survival when compared with starting on HD treatment, PD was often not selected as initial dialysis modality. Over time, we observed a significant decline in PD use and a stabilization in HD use. These observations were explained by the lower incidence rate of PD and HD and the increase in pre-emptive transplantation. © The Author 2015.

    Population-based studies on ovarian cancer providing survival estimates by age, histology, laterality, and stage have been sparse. We aimed to derive the most up-to-date and detailed survival estimates for ovarian cancer patients in Germany. We used a pooled German national dataset including data from 11 cancer registries covering 33 million populations. A total of 21 651 patients diagnosed with ovarian cancer in 1997-2006 were included. Period analysis was carried out to calculate the 5-year relative survival (RS) for the years 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age adjustment was performed using five age groups (15-44, 45-54, 55-64, 65-74, and 75+ years). Overall, the age-adjusted 5-year RS in 2002-2006 was 41%. A strong age gradient was observed, with a decrease in the 5-year RS from 67% in the age group 15-49 years to 28% in the age group 70+ years. Furthermore, the prognosis varied markedly by histology, laterality, and stage, with the age-adjusted 5-year RS ranging from 25% (for carcinoma not otherwise specified) to 81% (for stromal cell carcinoma), reaching 46% for unilateral and 32% for bilateral carcinoma and reaching 82% for Federation of Gynecology and Obstetrics (FIGO) stages I and II, 36% for FIGO stage III, and 18% for FIGO stage IV. No improvement in survival could be observed for any of the subgroups in the period between 2002 and 2006. Our analyses suggest that an improvement in the 5-year RS for ovarian cancer may have stagnated in the early 21st century and underline the need for a more effective translation of therapeutic innovation into clinical practice.

    The outcome of cholangiopathy developing in intensive care unit (ICU) is not known in patients surviving their ICU stay. To perform a survey in liver units, in order to clarify the course of cholangiopathy after surviving ICU stay. The files of the liver units affiliated to the French network for vascular liver disease were screened for cases of ICU cholangiopathy developing in patients with normal liver function tests on ICU admission, and no prior history of liver disease. Between 2005 and 2015, 16 cases were retrieved. Extensive burns were the cause for admission to ICU in 11 patients. Serum alkaline phosphatase levels increased from day 11 (2-46) to a peak of 15 (4-32) × ULN on day 81 (12-511). Magnetic resonance cholangiography showed irregularities or frank stenosis of the intrahepatic ducts, and proximal extrahepatic ducts contrasting with a normal aspect of the distal common bile duct. Follow-up duration was 20.6 (4.7-71.8) months. Three patients were lost to follow-up; 2 patients died from liver failure and no patient was transplanted. One patient had worsening strictures of the intrahepatic bile ducts with jaundice. Nine patients had persistent but minor strictures of the intrahepatic bile ducts on MR cholangiography, and persistent cholestasis without jaundice. One patient had normal liver function tests. In patients surviving their ICU stay, ICU cholangiopathy is not uniformly fatal in the short term or clinically symptomatic in the medium term. Preservation of the distal common bile duct appears to be a finding differentiating ICU cholangiopathy from other diffuse cholangiopathies. © 2017 John Wiley & Sons Ltd.

    OBJECTIVES: To investigate the possible influence of attendance at cultural events, reading books or periodicals, making music or singing in a choir as determinants for survival. DESIGN: A simple random sample was drawn of 15,198 individuals aged 16-74 years. Of these, 85% (12,982) were interviewed by trained non-medical interviewers between 1982 and 1983 about cultural activities. They were followed up with respect to survival until 31 December 1991. SETTING: Swedish interview survey of living conditions comprising a random sample of the adult Swedish population. SUBJECTS: 12,675 people interviewed between 1982 and 1983. MAIN OUTCOME MEASURES: Survival of subjects after controlling for eight confounding variables: age, sex, education level, income, long term disease, social network, smoking, and physical exercise. RESULTS: 6,301 men and 6,374 women were followed up; 533 men and 314 women died during this period. The control variables influenced survival in the expected directions except for social network for men; a significant negative effective was found when the analysis was made separately for men and women. We found an influence on mortality when the eight control variables were controlled for in people who rarely attended events compared with those attending most often, the relative risk being 1.57 (95% confidence interval 1.18 to 2.09). CONCLUSION: Attendance at cultural events may have a positive influence on survival. Long term follow up of large samples with confounders that are well controlled for and with the cultural stimulation more highly specified should be used to try to falsify the hypothesis before experiments start.

    Full Text Available Abstract Background It is unclear whether individualized treatments based on biological factors have improved the prognosis of recurrent breast cancer. The purpose of this study is to evaluate the survival improvement of patients with recurrent breast cancer after the introduction of third generation aromatase inhibitors (AIs and trastuzumab. Methods A total of 407 patients who received first diagnosis of recurrent breast cancer and treatment at National Kyushu Cancer Center between 1992 and 2008 were retrospectively evaluated. As AIs and trastuzumab were approved for clinical use in Japan in 2001, the patients were divided into two time cohorts depending on whether the cancer recurred before or after 2001. Cohort A: 170 patients who were diagnosed between 1992 and 2000. Cohort B: 237 patients who were diagnosed between 2001 and 2008. Tumor characteristics, treatments, and outcome were compared. Results Fourteen percent of cohort A and 76% of cohort B received AIs and/or trastuzumab (P Conclusions The prognosis of patients with recurrent breast cancer was improved over time following the introduction of AIs and trastuzumab and the survival improvement was apparent in HR- and/or HER-2-positive tumors.

    Lower eGFR 1 year after kidney transplant is associated with shorter allograft and patient survival. We examined how practice changes in the past decade correlated with time trends in average eGFR at 1 year after kidney transplant in the United States in a cohort of 189,944 patients who received a kidney transplant between 2001 and 2013. We calculated the average eGFR at 1 year after transplant for the recipient cohort of each year using the appropriate Modification of Diet in Renal Disease equation depending on the prevailing methodology of creatinine measurement, and used linear regression to model the effects of practice changes on the national post-transplant eGFR trend. Between the 2001-2005 period and the 2011-2013 period, average 1-year post-transplant eGFR remained essentially unchanged, with differences of 1.34 (95% confidence interval, 1.03 to 1.65) ml/min per 1.73 m2 and 0.66 (95% confidence interval, 0.32 to 1.01) ml/min per 1.73 m2 among deceased and living donor kidney transplant recipients, respectively. Over time, the mean age of recipients increased and more marginal organs were used; adjusting for these trends unmasked a larger temporal improvement in post-transplant eGFR. However, changes in immunosuppression practice had a positive effect on average post-transplant eGFR and balanced out the negative effect of recipient/donor characteristics. In conclusion, average 1-year post-transplant eGFR remained stable, despite increasingly unfavorable attributes in recipients and donors. With an aging ESRD population and continued organ shortage, preservation of average post-transplant eGFR will require sustained improvement in immunosuppression and other aspects of post-transplant care.

    OBJECTIVE: The prognosis for colorectal cancer (CRC) is less favourable in Denmark than in neighbouring countries. To improve cancer treatment in Denmark, a National Cancer Plan was proposed in 2000. We conducted this population-based study to monitor recent trends in CRC survival and mortality...... for age and gender. A total of 19,515 CRC patients were identified and linked with the Central Office of Civil Registration to ascertain survival through January 2005. Results: From 1985 to 2004, 1-year and 5-year survival improved both for patients with colon and rectal cancer. From 1995-1999 to 2000......-2004, overall 1-year survival of 65% for colon cancer did not improve, and some age groups experienced a decreasing 1-year survival probability. For rectal cancer, overall 1-year survival increased from 71% in 1995-1999 to 74% in 2000-2004. Using 1985-1989 as reference period, 30-day mortality did not decrease...

    Dental implants have been increasingly used for prosthodontic rehabilitation of patients following oral tumor resection and postsurgical radiotherapy. However, only a few long-term studies have examined the implant survival rate and other factors related to prosthodontic treatment in oral tumor resection patients. The purpose of this study was to evaluate the long-term survival of dental implants and implant-retained prostheses in oral cancer resection patients. Ninety-three patients (63 men, 30 women) with a mean age of 59 years (range of 26-89 years) received 435 implants after the resection of a head and neck tumor. Twenty-nine patients received postsurgical radiotherapy prior to implant placement. The factors related to implant survival or failure were monitored over a mean observation period of 10.3 years (range of 5 to 161 months). Prosthodontic rehabilitation was evaluated with respect to the rates of technical failures and complications. Data were analyzed using a Kaplan-Meier curve and comparisons were made with the log-rank test or the Wilcoxon test (a=.05). Of the 435 implants, 43 implants were lost; the cumulative survival rate was 92%, 84%, and 69% after 3.5, 8.5, and 13 years, respectively. Twenty-eight implants in 6 patients were counted as lost since the patients had died. Twenty-nine irradiated patients received 124 implants, of which 6 implants were lost prior to prosthodontic rehabilitation. In 68 patients with 78 rigid bar-retained dentures, only minor technical complications were identified. However, all 25 fixed implant-supported restorations had no technical component failures and did not require technical maintenance. This study demonstrates that implant-retained and -supported prostheses in oral cancer resection patients, irrespective of the cancer treatment procedure, show lower long-term survival rates than those in patients without prior cancer surgery. Rigid fixation of the implant-supported prosthesis appears to minimize the

    The purpose of this systematic review was to compare the survival and complication rates of ceramic veneers produced with different techniques and materials after a minimum follow-up time of 5 years. A literature search was conducted, using electronic databases, relevant references, citations and journal researching, for clinical studies reporting on the survival of ceramic veneers fabricated with different techniques and materials with a mean followup time of at least 5 years. The search period spanned from January 1980 up to October 2010. Event rates were calculated for the following complications associated with ceramic veneers: fracture, debonding, marginal discoloration, marginal integrity, and caries. Summary estimates, and 5-year event rates were reported. Comparison between subgroups of different materials, as well as statistical significance, was calculated using a mixed effects model. Nine studies were selected for final analysis over an initial yield of 409 titles. No study directly compared the incidence of complications between ceramic veneers fabricated from different materials. Four of the included studies reported on the survival of ceramic veneers made out of feldspathic ceramics; four studies were on glass-ceramic veneers and one study included veneers fabricated from both materials. The mean observation time ranged between 5 and 10 years. Overall, the 5-year complication rates were low, with the exception of studies reporting on extended ceramic veneers. The most frequent complication reported was marginal discoloration (9% at 5 years), followed by marginal integrity (3.9-7.7% at 5 years). There was no statistically significant difference in the event rates between the subgroups of different materials (feldspathic vs. glass-ceramic). The results of this systematic review showed that ceramic veneers fabricated from feldspathic or glass-ceramics have an adequate clinical survival for at least 5 years of clinical service, with very low complication

    Full Text Available The impact of dialysis modality on survival is still somewhat controversial. Given possible differences in patients' characteristics and the cause and rate of death in different countries, the issue needs to be evaluated in Korean cohorts.A nationwide prospective observational cohort study (NCT00931970 was performed to compare survival between peritoneal dialysis (PD and hemodialysis (HD. A total of 1,060 end-stage renal disease patients in Korea who began dialysis between September 1, 2008 and June 30, 2011 were followed through December 31, 2011.The patients (PD, 30.6%; HD, 69.4% were followed up for 16.3 ± 7.9 months. PD patients were significantly younger, less likely to be diabetic, with lower body mass index, and larger urinary volume than HD patients. Infection was the most common cause of death. Multivariate Cox regression with the entire cohort revealed that PD tended to be associated with a lower risk of death compared to HD [hazard ratio (HR 0.63, 95% confidence interval (CI 0.36-1.08]. In propensity score matched pairs (n=278 in each modality, cumulative survival probabilities for PD and HD patients were 96.9% and 94.1% at 12 months (P=0.152 and 94.3% and 87.6% at 24 months (P=0.022, respectively. Patients on PD had a 51% lower risk of death compared to those on HD (HR 0.49, 95% CI 0.25-0.97.PD exhibits superior survival to HD in the early period of dialysis, even after adjusting for differences in the patients' characteristics between the two modalities. Notably, the most common cause of death was infection in this Korean cohort.

    Sexual conflict is magnified during the post-fledging period of birds when the sexes face different trade-offs between continuing parental care or investing in self maintenance or other mating opportunities. Species with reversed sex roles provide a unique opportunity to study the relationship between mating systems and investment in parental care. Here, we provide the first detailed study of the length of care by males versus females (n = 24 pairs) during the post-fledging period, assessing factors that may promote care within and between the sexes. In the northern flicker Colaptes auratus, a species with partly reversed sex roles, males cared longer than females (average 16 versus 12 days, respectively). Overall, 36% of females but no males deserted the brood prior to fledgling independence. Parents that provisioned nestlings at a high rate also spent more days feeding fledglings. Among males, age and nestling feeding rates were positively associated with the length of care. Among females, a low level of feather corticosterone (CORTf) was associated with a longer length of care. About 45% of fledglings died within the first week, but fledglings with intermediate body mass had the highest survival suggesting stabilizing selection on mass. Fledgling survival was also higher in individuals with larger broods and lower levels of CORTf. We demonstrate that because females can be polyandrous they often desert the brood before males, and that the sexes respond to different cues relating to their energy balance when deciding the length of care given to their offspring.

    Full Text Available Case histories of 366 patients with cancer of the oral mucosa, tongue, and oropharynx who had received cryogenic treatment at the N.N. Blokhin Russian Cancer Research Center in the period 1975 to 2009 served as the material for the investigation. Analysis of the longterm results of cryogenic treatment for primary and recurrent cancers and tumors untreated after traditional treatments showed the efficiency of this method in 75.8 and 48.2 % of primary and recurrent cancer patients, respectively. Five- and ten-year relapse-free survival rates were 73 and 68 %, respectively; and the survival rates after 15 years remained stable and those after 20 years averaged 65 % for all sites of oropharyngeal cancer. Recurrent cancer occurred in 21.4 % of the 303 patients who had completed treatment: in 15.2 % of the patients with primary cancer and in 21.7 % of those with recurrent cancer and untreated tumors. Local complications emerged from the wound in 18.3 % and were arrested in the postoperative period. Cryogenic treatment is recommended for oncological practice; its indications and contraindications were defined.

    The Caribbean population of Guadeloupe has one of the highest incidence rates of prostate cancer worldwide. In 2008, a population-based cancer registry was set up for the monitoring of cancer incidence in the aftermath of the environmental pollution with chlordecone, a persistent organochlorine insecticide formerly used in banana plantations. We describe the clinical presentation, incidence, mortality and survival of prostate cancer for the period 2008-2013. The Guadeloupe cancer registry has been routinely collecting all incident cases of cancer since 2008. We compared age-specific incidence rates between different populations, and calculated incidence and mortality rates standardized to the world population. Kaplan-Meier observed survival and estimated age-standardized net survival were calculated by category for age, PSA level, and Gleason score using the Pohar-Perme method. Overall, 3,295 cases of prostate cancer were recorded. World-standardized incidence and mortality were respectively 184.1 [177.8-190.4] and 23.9 [21.9-25.7] per 100,000 person-years. At diagnosis, the mean age of patients was 68 ± 9.6 years old and 22% were aged over 75. Median PSA level was 8.9 [IQR: 6.0-16.0] and 13.6% of the patients had a Gleason ≥ 8. Five-year observed and net survivals were, respectively, 79.6% [77.9-81.2] and 90.7% [88.6-92.8]. The incidence of prostate cancer in Guadeloupe is among the highest in the world, along with those of the neighboring Caribbean countries and US African-Americans. We observed no decrease in incidence rates, and a decreasing but non-significant trend in mortality rates, which nonetheless remain higher than in high-income countries. Many Genome-Wide Association Studies are conducted to identify genetic markers involved in prostate cancer risk. In the Caribbean, complementary studies on both lifestyle and behavioral factors should highlight potential common risks among populations who share both genetic and environmental

    This analysis presents the survival of patients starting renal replacement therapy (RRT) in UK renal units ('centres'), and includes an analysis of survival by centre. Data from 59 of the 70 UK centres are included. This is the first year that UK centre anonymity has been removed from analysis of patient survival by centre. Survival after adjustment for comorbidity is also reported for the first time although this analysis is restricted to those centres returning data on comorbidity in at least 85% of incident patients. The importance of adjusting for comorbidity can be seen in that for one centre, after adjustment of survival for age and diagnosis, the adjusted 1 year after 90 day survival was 84.6%. After adjusting to the average comorbidity present across centres, survival increased to 90.4%. Improved comorbidity data returns by renal units may require investment in informatics staff and creating structural process at renal unit level for clinicians to support these data returns. From the date of first RRT, the 1 year survival of all patients (unadjusted for age) is 79%. From the 90th day of RRT (to allow comparison with other countries' 1 year survival), the 1 year survival is 83%. The age adjusted (60 years) survival for the 1 year after 90 day period is 86%. There is a high death rate in the first 90 days on RRT (6% of all patients starting RRT), a period not included in reports by many registries and other studies. The 5 year survival (including deaths within the first 90 days) rates are 58, 53, 44, 28, 19 and 12%, respectively for patients aged 18-34, 35-44, 45-54, 55-64, 65-74 and >75 years. The 'vintage effect' of increasing hazard of death with length of time on RRT, prominent in data from the US, is only noted in older age groups (65-75 and 75+ years) at 5-6 years after starting RRT. Six centres had a figure for the 1 year after 90 day survival which was outside 2 SDs from the mean for the UK: in three cases this was better survival, and in three

    Very little data exist on the incidence and burden of cancer in the individual Caribbean countries. Some data are available for larger areas, reported under a bigger geographical region; Latin America and the Caribbean, but many of the individual countries are not included. One of the main reasons is a lack of official cancer registries. Data are usually collected from hospital records or private physician records, and since it is not in an official registry, these data are not always accessible for inclusion in databases such as SEER and GLOBOCAN. Grenada is one of the countries that currently does not have a registry. Our aim is to report on the incidence for head and neck cancer with subcategories; hypopharynx, oropharynx, oral cavity, salivary glands, and larynx from data collected by the sole ear nose and throat specialist over a 20-year period. The age adjusted incidence per 100,000 for these cancers, whether combined or individually, is lower than that of similar populations. The incidence in males is only slightly higher than those reported in some parts of Africa. In females, only Eastern Africa is reported to have a lower incidence than that found in our study. While the incidence of oral cancers is lower than that of African Americans, the survival rate is comparable. Socioeconomic status, lack of infrastructure, and advanced stage at diagnosis appear to be closely related to the survival rate. Incidence reports suggest that incidence of head and neck cancers in individuals of African descent is lower than other populations. It is therefore not surprising that the incidence in Grenada is relatively low, although the incidence may be underestimated.

    The aim was to compare 5-year survival in two included cohorts (from year 2000 and year 2007) of 249 nursing home residents (NHR) in this retrospective, comparative study. The cohorts were compared regarding chronic diseases, medication, physical/cognitive/nutritional status, body mass index, body temperature and 5-year mortality. Factors correlated with 5-year survival were determined using Cox regression analysis. In average, cohort 2007 survived 31 ± 16 months and cohort 2000, 38 ± 13 months, p nursing homes (NH), more dependent in activities of daily living (ADL), had dementia, stroke, autoimmune disease and treatment with antidepressants, while malnutrition and treatment with paracetamol were more common 2000. In 2000, medication with antidepressants, the presence of stroke and diabetes, irrespective of gender, and in women cardiovascular disease, two to threefold significantly increased survival, while autoimmune disease, influenza vaccination and dependency in ADL decreased survival. In 2007, maintaining BMI, irrespective of gender, and autoimmune disease and COPD in women significantly increased survival, while malnutrition, influenza vaccination, dependency in ADL and medication with sedatives/tranquillisers or paracetamol severely reduced survival. The present results indicate a trend that individuals are older and frailer when admitted to NH and that survival time after admission has been shortened. Hence, the need of daily support and care has increased, irrespective of housing. Also, predictors of survival, possible to influence, have changed. © 2016 Nordic College of Caring Science.

    To measure the maxillary dentoskeletal and soft tissue changes of severely obstructed mouth breathing (MB) young children who had their mode of breathing normalized after adenotonsillectomy (T&A), in comparison with a matched group of severely obstructed untreated MB children (CG). Seventy patients who had an Ear, Nose, and Throat examination (ENT), including flexible nasal endoscopy, to confirm the severe obstruction of the upper airways and the indication of T&A composed the sample. Cephalograms and dental casts were available from the patient's orthodontic records. Treatment group (TG) and CG included 35 children each. Groups were matched by gender (24 males and 11 females in each group), age (TG, 6.7 ± 1.8 years; CG, 6.9 ± 2.3 years), tooth development (TG, 13 primary dentition, 22 mixed dentition; CG, 14 primary dentition, 21 mixed dentition), and skeletal maturation status. Records were taken at baseline (T0) and 1-year after T&A (T1) for TG; while CG records were taken with a 1-year interval. Dentoskeletal measurements were performed in the lateral cephalograms, and dental casts were used to assess the palatal volume and occlusal changes. TG showed a significant increase (503.3 mm(3), P palatal volume (10% of change), while CG palatal volume was stable. No dimensional occlusal changes were detected between T0 and T1 in both groups. Significant downward (point A, 2.1 mm; ANS, 2.1 mm) and forward displacements (point A, 0.7 mm; ANS, 1 mm) of the anterior region of the maxilla were observed in the TG, but CG presented only significant downward displacement (point A, 1.8 mm; ANS, 1.4 mm). The maxillary posterior region (PNS, PTM, and Molar) displaced downward in both groups (P palatal plane inclination was stable in both groups. TG presented significant increase in the palatal volume and in the forward displacement of the maxilla. No other significant maxillary dentoskeletal changes were found.

    This 1-year randomized clinical trial compared the bone regeneration and success rates between immediate and conventional loading of dental implants placed immediately after extraction in patients with a past history of periodontal disease. Sixty patients who chose an immediate implant treatment option to replace a hopeless tooth were included in this study. Patients were randomly assigned to receive immediate implants with either immediate loading (group A) or conventional loading after 3 months (group B). At baseline, both groups received a mucoperiosteal flap, extraction, implant placement, allograft bone, and a membrane. Group A received a provisional crown. In group B, a cover screw was placed and primary closure was achieved. The patients were evaluated at 3, 6, and 12 months postoperatively. The 1-year implant survival rate was 95% for the whole study group: 96.6% for group A, and 93.3% for group B. The bone level increased significantly in both groups (group A: 0.99 ± 0.22 mm; group B: 0.75 ± 0.17 mm), and the difference was not statistically significant (p > 0.5). At the 1-year postoperative visit, the mucogingival junction (MGJ) was found to be displaced coronally in 65% of implant sites in group B compared with 15% sites in group A. Both the immediate and delayed loading of immediately placed implants showed similar outcome with regards to treatment success rates and stability of radiographic bone level. Submerging an immediately placed implant and primary soft tissue closure did not show significant outcome advantages over the transmucosal approach. © 2010 Wiley Periodicals, Inc.

    In the peripheral blood leukocytes (PBLs) from the carriers of the human T-lymphotropic virus type-1 (HTLV-1) or the patients with adult T-cell leukemia (ATL), nuclear factor kappaB (NF-κB)-mediated antiapoptotic signals are constitutively activated primarily by the HTLV-1-encoded oncoprotein Tax. Tax interacts with the I κB kinase regulatory subunit NEMO (NF-κB essential modulator) to activate NF-κB, and this interaction is maintained in part by a molecular chaperone, heat-shock protein 90 (HSP90), and its co-chaperone cell division cycle 37 (CDC37). The antibiotic geldanamycin (GA) inhibits HSP90's ATP binding for its proper interaction with client proteins. Administration of a novel water-soluble and less toxic GA derivative, 17-dimethylaminoethylamino-17-demethoxygeldanamycin hydrochloride (17-DMAG), to Tax-expressing ATL-transformed cell lines, C8166 and MT4, induced significant degradation of Tax. 17-DMAG also facilitated growth arrest and cellular apoptosis to C8166 and MT4 and other ATL cell lines, although this treatment has no apparent effects on normal PBLs. 17-DMAG also downregulated Tax-mediated intracellular signals including the activation of NF-κB, activator protein 1 or HTLV-1 long terminal repeat in Tax-transfected HEK293 cells. Oral administration of 17-DMAG to ATL model mice xenografted with lymphomatous transgenic Lck-Tax (Lck proximal promoter-driven Tax transgene) cells or HTLV-1-producing tumor cells dramatically attenuated aggressive infiltration into multiple organs, inhibited de novo viral production and improved survival period. These observations identified 17-DMAG as a promising candidate for the prevention of ATL progression.

    To present the outcomes of immediately loaded single implants placed in the anterior maxilla. Over a 2-year period, all patients referred to a private clinic were considered for enrolment in this study. Inclusion criteria were single-tooth placement in postextraction sockets or healed sites of the anterior maxilla. All implants were immediately loaded and followed for a period of 1 year after the placement of definitive crowns. The outcome measures were implant stability, survival, and success. 34 patients were selected and 43 tapered implants with a knife-edge thread design and a nanostructured, calcium-incorporated surface (Anyridge®, Megagen, Gyeongsang, Korea) were installed. Two implants were not sufficiently stable at placement (ISQ immediate loading; 41 implants had an ISQ ≥ 60 at placement and were immediately loaded. One year after the placement of definitive crowns, no implant failures were reported, for a survival rate of 100%. No biological complications were found, but 2 implants had their prosthetic abutments loosened: the implant success rate was 95.2%. In the present study on the immediate loading of single implants in the anterior maxilla, positive outcomes were reported, with high survival (100%) and success (95.2%) rates (the present study has been registered in the ISRCTN registry, a publicly available trial register recognized by WHO and ICMJE, with number ISRCTN12935478).

    The aim of this study is to determine the survival of live births with trisomy 18 and trisomy 13 and their variants. Information on live births with trisomy 18 or trisomy 13 recorded in the National Down Syndrome Cytogenetic Register (NDSCR) was linked by the NHS Information Centre to obtain information about survival. Survival was known for 326 (88%) of live births with trisomy 18 and 142 (82%) of live births with trisomy 13 born in England and Wales between 2004 and 2011. The median survival time for live births with full trisomy 18 was 14 days and with full trisomy 13 was 10 days, the 3-month survival was 20% and 18%, respectively, and the 1-year survival for both syndromes was 8%. The 1-year survival for live births with trisomy 18 mosaicism (n = 17) was 70%, for those with trisomy 13 mosaicism (n = 5) was 80% and for those with partial trisomy 13 (Robertsonian translocations) (n = 17) was 29%. This study is based on the largest data set on survival for live births with trisomy 18 and trisomy 13. Although median survival for these children is 2 weeks or less, about one in five survive for 3 months or more and about 1 in 12 survive for 1 year or more. We suggest that these survival rates are used in counselling as well as the median survival time. Copyright © 2013 Wiley Periodicals, Inc.

    The aim of the study was to measure the effect of radiological hip and elbow dysplasia status and breed on overall survival in a cohort of four large dog breeds in Norway. Privately owned dogs of the Newfoundland (NF), Labrador Retriever (LR), Leonberger (LEO), and Irish Wolfhound (IW) breeds were followed prospectively from birth to 10 years of age. The age of death/euthanasia was registered. A total of 501 dogs from 103 litters were enrolled. Kaplan-Meier survival curves were used to describe breed differences in survival times. The effects of radiological hip and elbow dysplasia status as well as breed were assessed using a Cox proportional hazards model. The variables 'sex' and 'living region' were explored as potential confounders. Among LRs, 60.2% of the dogs were still alive at 10 years of age, and the corresponding figures for NFs, LEOs, and IWs were 28.8%, 16.11%, and 6.4%, respectively. Radiological hip dysplasia status and breed were found to influence overall survival. Two different time-varying effects were observed in that with the IW the hazard of death increased linearly through time, while the effect of severe radiological hip dysplasia decreased logarithmically with time. Location influenced the death hazard and dogs living in suburban areas or cities had longer mean time to death and a lower hazard compared to dogs living in the countryside. Radiological elbow dysplasia status was not found to have an effect on overall survival. Copyright © 2011 Elsevier Ltd. All rights reserved.

Controversial data exist regarding the impact of sodium dysregulation on patient survival after heart transplantation (HTX). The aim of this study was to investigate the influence of donor sodium levels on survival in a large cohort of heart transplant recipients from the Eurotransplant registry. From 1997 to 2005, all consecutive adult HTX performed in the Eurotransplant region were included into this study (n = 4641 patients). Multivariate analysis was applied to investigate possible clinical predictors for 1-year post-transplant survival after cardiac transplantation (donor sodium levels, donor age, donor cause of death, recipient age, primary disease, urgency status, cold ischemia time). In multivariate analysis, recipients receiving a donor heart with serum sodium level lower than 130 mmol/l or higher than 170 mmol/l had a 1.25-fold higher risk for 1-year post-transplant mortality than patients with normal donor sodium ranges (P = 0.007). Other independent risk factors for impaired 1-year survival were recipient age, the indication for transplantation and the urgency status of the recipient. Our study demonstrates that hyponatremia as well as hypernatremia show a strong U-shaped correlation with poor survival after cardiac transplantation. Accurate donor management to avoid electrolyte disorder seems to be crucial for ensuring good quality of donor hearts.

    The effect of bystander interventions on long-term functional outcomes among survivors of out-of-hospital cardiac arrest has not been extensively studied. We linked nationwide data on out-of-hospital cardiac arrests in Denmark to functional outcome data and reported the 1-year risks of anoxic brain damage or nursing home admission and of death from any cause among patients who survived to day 30 after an out-of-hospital cardiac arrest. We analyzed risks according to whether bystander cardiopulmonary resuscitation (CPR) or defibrillation was performed and evaluated temporal changes in bystander interventions and outcomes. Among the 2855 patients who were 30-day survivors of an out-of-hospital cardiac arrest during the period from 2001 through 2012, a total of 10.5% had brain damage or were admitted to a nursing home and 9.7% died during the 1-year follow-up period. During the study period, among the 2084 patients who had cardiac arrests that were not witnessed by emergency medical services (EMS) personnel, the rate of bystander CPR increased from 66.7% to 80.6% (Pthe rate of bystander defibrillation increased from 2.1% to 16.8% (Pthe rate of brain damage or nursing home admission decreased from 10.0% to 7.6% (Pbystander CPR was associated with a risk of brain damage or nursing home admission that was significantly lower than that associated with no bystander resuscitation (hazard ratio, 0.62; 95% confidence interval [CI], 0.47 to 0.82), as well as a lower risk of death from any cause (hazard ratio, 0.70; 95% CI, 0.50 to 0.99) and a lower risk of the composite end point of brain damage, nursing home admission, or death (hazard ratio, 0.67; 95% CI, 0.53 to 0.84). The risks of these outcomes were even lower among patients who received bystander defibrillation as compared with no bystander resuscitation. In our study, we found that bystander CPR and defibrillation were associated with risks of brain damage or nursing home admission and of death from any cause that were

    A new type of titanium framework has been introduced, but so far no clinical reports have been made in this treatment modality. The aim of this study was to report the clinical performance of implant-supported prostheses with computer numeric controlled (CNC)-milled titanium frameworks in the edentulous jaw and to compare the results with prostheses provided with conventional cast frameworks during the first year of function. A consecutive group of 65 patients with 67 prostheses were provided with CNC-milled titanium frameworks in 23 upper and 44 lower jaws. During the same period, 61 consecutive patients were treated on a routine basis with 31 upper and 31 lower conventional gold alloy casting prostheses. Clinical and radiographic 1-year data were collected for both the test and control groups. A total of 14 of 729 inserted implants were lost during the follow-up period (1.9%). All prostheses were functioning after 1 year except a conventional prosthesis with a cast framework, which was replaced by an implant-supported over-denture due to implant loss. The 1-year cumulative survival rate (CSR) was 100% and 97.8% for CNC prostheses and implants, respectively. The corresponding CSR for the control group was 98.3% and 98.3%, respectively. Few problems were reported in both groups, and the clinical and the radiologic performances were similar for both groups. No mechanical complications except some resin veneer fractures (n = 6) were observed. The mean marginal bone loss for the test group during the first year in function was 0.4 mm (SD = 0.35) and 0.4 mm (SD = 0.33) in the upper and lower jaws, respectively. A similar pattern of bone reaction was also observed in the control group. CNC-milled titanium frameworks can be used as an alternative to conventional castings in the edentulous jaw, presenting similar clinical and radiologic performances as conventional cast frameworks during the first year of function.

    We have made substantial progress toward our objectives outlined in our BPA supported proposal entitled 'Columbia River Basin Juvenile Salmonids: Survival and Growth in the Columbia River Plume and northern California Current' which we report on herein. During 2008, we were able to successfully conduct 3 mesoscale cruises. We also were able to conduct 7 biweekly predator cruises, along with substantial shore-based visual observations of seabirds. Detailed results of the mesoscale cruises are available in the Cruise Reports and summarized in the next section. We have taken a proactive approach to getting the results of our research to fisheries managers and the general public. We have begun to make annual predictions based on ocean conditions of the relative survival of juvenile coho and Chinook salmon well before they return as adults. This is based on both biological and physical indicators that we measure during our surveys or collect from outside data sources. Examples of our predictions for 2009 and 2010 are available on the following web site: http://www.nwfsc.noaa.gov/research/divisions/fed/oeip/a-ecinhome.cfm.

    Full Text Available BACKGROUND: Many chronic renal patients lack autologous veins in the upper limbs suitable for construction of arteriovenous fistulas for hemodialysis. Alternative fistula options for these patients should be evaluated and compared.OBJECTIVE: To compare different types of grafts used for brachioaxillary access in hemodialysis patients in terms of their patency and complication rates.METHOD: Forty-nine patients free from arterial system abnormalities and with no venous options for creation of arteriovenous fistulae in the arm and/or forearm underwent brachioaxillary bypass with implantation of autologous saphenous vein, polytetrafluoroethylene (PTFE, or PROPATEN(r grafts. Patients were assessed by Doppler ultrasonography at 3, 6, and 12 months after surgery,.RESULTS: The four first saphenous vein grafts had failed by 3 or 6 months after surgery. The autologous saphenous vein group was discontinued at the beginning of the study because of extreme difficulty in achieving puncture and hematoma formation. Failure rates of PTFE and PROPATEN(r grafts did not differ after 3 (p = 0.559, 6 (p = 0.920, or 12 months (p = 0.514. A log-rank test applied to cumulative survival of grafts at 1 year (0.69 for PTFE, 0.79 for PROPATEN(r detected no significant differences (p = 0.938. There were no differences in complications resulting in graft failure between the two types of prosthetic graft.CONCLUSION: Autologous saphenous vein grafts do not appear to be a good option for brachioaxillary hemodialysis access because of difficulties with achieving puncture. Brachioaxillary fistulae constructed using PTFE or PROPATEN(r grafts exhibited similar patency and complication rates. Further studies with large samples size are warranted to confirm our findings.

    Globally, reanalysis data sets are widely used in assessing climate change, validating numerical models, and understanding the interactions between the components of a climate system. However, due to the relatively coarse resolution, most global reanalysis data sets are not suitable to apply at the local and regional scales directly with the inadequate descriptions of mesoscale systems and climatic extreme incidents such as mesoscale convective systems, squall lines, tropical cyclones, regional droughts, and heat waves. In this study, by using a data assimilation system of Gridpoint Statistical Interpolation, and a mesoscale atmospheric model of Weather Research and Forecast model, we build a regional reanalysis system. This is preliminary and the first experimental attempt to construct a high-resolution reanalysis for China main land. Four regional test bed data sets are generated for year 2013 via three widely used methods (classical dynamical downscaling, spectral nudging, and data assimilation) and a hybrid method with data assimilation coupled with spectral nudging. Temperature at 2 m, precipitation, and upper level atmospheric variables are evaluated by comparing against observations for one-year-long tests. It can be concluded that the regional reanalysis with assimilation and nudging methods can better produce the atmospheric variables from surface to upper levels, and regional extreme events such as heat waves, than the classical dynamical downscaling. Compared to the ERA-Interim global reanalysis, the hybrid nudging method performs slightly better in reproducing upper level temperature and low-level moisture over China, which improves regional reanalysis data quality.

    Breast cancer is the most common cancer among women worldwide. The Nordic countries have relatively high survival, but Denmark has a lower survival than neighboring countries. A breast cancer screening program was introduced in 2007 and 2008 in the northern and central regions of Denmark respectively. We aimed to examine possible changes in survival of Danish breast cancer patients in central and northern Denmark in the period 1998-2009. From the northern and central Denmark regions, we included all women (n = 13,756) with an incident diagnosis of breast cancer, as recorded in the Danish National Registry of Patients during the period January 1, 1998 through December 31, 2009. We calculated age-stratified survival and used Cox proportional hazard regression to estimate mortality rate ratios (MRRs) for all breast cancer patients. Median age was 62 years (21-102 years). The overall 1-year survival improved steadily over the period from 90.9% in 1998-2000 to 94.4% in 2007-2009, corresponding to a 1-year age adjusted MRR of 0.68 in 2007-2009 compared with the reference period 1998-2000. We estimated the 5-year survival to improve from 70.0% in 1998-2000 to 74.7% in 2007-2009, corresponding to a 5-year age adjusted MRR of 0.82 in 2007-2009 compared with the reference period 1998-2000. For middle-aged women (50-74 years) 1-year survival increased from 92.8% in 1998-2000 to 96.6% in 2008-2009, and 5-year survival was expected to increase from 73.9% in 1998-2000 to 80.2% in 2007-2009. Among younger women (15-49 years) and elderly women (>75 years), 1-year survival and 5-year predicted survival did not change over the two time periods. Survival of breast cancer patients has improved in Denmark over the period 1998-2009, and this change was most distinct in women aged 50-74 years. Survival improved even before the implementation of a formal breast cancer screening program.

    Religiosity and spirituality have been associated with better survival in large epidemiologic studies. This study examined the relationship between spiritual absence and 1-year all-cause mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Depression and problematic compliance were examined as possible mediators of a significant spiritual absence-mortality relationship. Eighty-five adults (mean = 46.85 years old, SD = 11.90 years) undergoing evaluation for allogeneic HSCT had routine psychologie evaluation prior to HSCT admission. The Millon Behavioral Medicine Diagnostic was used to assess spiritual absence, depression, and problematic compliance, the psychosocial predictors of interest. Patient status at 1 year and survival time in days were abstracted from medical records. Cox regression analysis was used to examine the relationship between the psychosocial factors of interest and mortality after adjusting for relevant biobehavioral factors. Twenty-nine percent (n = 25) of participants died within 1 year of HSCT. After covarying for disease type, individuals with the highest spiritual absence and problematic compliance scores were significantly more likely to die 1-year post-HSCT (hazard ratio [HR] = 2.49, P = .043 and HR = 3.74, P = .029, respectively), particularly secondary to infection, sepsis, or graft-versus-host disease (GVHD) (HR = 4.56, P = .01 and HR = 5.61, P = .014), relative to those without elevations on these scales. Depression was not associated with 1-year mortality, and problematic compliance did not mediate the relationship between spiritual absence and mortality. These preliminary results suggest that both spiritual absence and problematic compliance may be associated with poorer survival following HSCT. Future research should examine these relations in a larger sample using a more comprehensive assessment of spirituality.

  9. Forms of Recall – Politics of Memory. Memory as the Non-Chronological Narrative Form of Historical-Political Identity Quest in the Kádár Regime and Its Survival in the Postcommunist Period

    Full Text Available In the film art of the Kádár regime the modernist non-chronological narrative mode became the dominant form of remembrance and communicative memory. In the 35-year period between 1956 and 1990 we can find thirty-five films of this type (e.g. Dialogue [Párbeszéd, János Herskó, 1963], Twenty Hours [Húsz óra, Zoltán Fábri, 1965], Cold Days [Hideg napok, András Kovács, 1966], Love [Szerelem, Károly Makk, 1971], Lovefilm [Szerelmesfilm, István Szabó, 1970], Diary for My Children [Napló gyermekeimnek, Márta Mészáros, 1982], the majority of which thematize the communicative memory of the recent past of the period (World War II, the Hungarian Holocaust, the 1950s, 1956, the Kádár consolidation as opposed to the amnesia politics of the time. Although this cinematic corpus is connected to the film history of the Kádár era with all its elements (form: modernism; theme: communicative memory; political discourse: recollection; official politics of memory; the counterdiscourse of Kádár’s amnesia politics, it survives in the postcommunist period (e.g. Hungarian Fragment [Pannon töredék, András Sólyom, 1998], White Palms [Fehér tenyér, Szabolcs Hajdu, 2006], Mom and Other Loonies in the Family [Anyám és más futóbolondok a családból, Ibolya Fekete, 2015]. After presenting the non-chronological narrative form of historical-political identity quest, the paper seeks to find reasons for the survival of this form and tries to draw conclusions regarding the social aspect and modes of expression of the Hungarian film history of the postcommunist period.

    Varicella universal vaccination (UV) has been implemented in many countries for several years. Nevertheless, varicella UV remains debated in Europe and few data are available on the real burden of infection. We assessed the burden of varicella in Belgium through analysis of hospitalised cases during a 1-year period. Data on children admitted to hospital with varicella were collected through a national network from November 2011 to October 2012. Inclusion criteria were either acute varicella or related complications up to 3 weeks after the rash. Participation of 101 hospitals was obtained, covering 97.7% of the total paediatric beds in Belgium. 552 children were included with a median age of 2.1 years. Incidence of paediatric varicella hospitalisations reached 29.5/10(5) person-years, with the highest impact among those 0-4 years old (global incidence and odds of hospitalisation: 79/10(5) person-years and 1.6/100 varicella cases, respectively). Only 14% (79/552) of the cohort had an underlying chronic condition. 65% (357/552) of children had ≥1 complication justifying their admission, 49% were bacterial superinfections and 10% neurological disorders. Only a quarter of children (141/552) received acyclovir. Incidence of complicated hospitalised cases was 19/10(5) person-years. Paediatric intensive care unit admission and surgery were required in 4% and 3% of hospitalised cases, respectively. Mortality among Belgian paediatric population was 0.5/10(6) and fatality ratio 0.2% among our cohort. Varicella demonstrated a substantial burden of disease in Belgian children, especially among the youngest. Our thorough nationwide study, run in a country without varicella UV, offers data to support varicella UV in Belgium. Published by the BMJ Publishing Group Limited.

    Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for heart failure (HF). Although some progress has been made in improving survival among patients admitted for HF, the rates of hospital readmissions and the related costs continue to rise dramatically. We sought to examine whether NAFLD and its severity (diagnosed at hospital admission) was independently associated with a higher risk of 1-year all-cause and cardiac re-hospitalization in patients admitted for acute HF. We studied 212 elderly patients who were consecutively admitted with acute HF to the Hospital of Negrar (Verona) over a 1-year period. Diagnosis of NAFLD was based on ultrasonography, whereas the severity of advanced NAFLD fibrosis was based on the fibrosis (FIB)-4 score and other non-invasive fibrosis scores. Patients with acute myocardial infarction, severe valvular heart diseases, end-stage renal disease, cancer, known liver diseases or decompensated cirrhosis were excluded. Cox regression was used to estimate hazard ratios (HR) for the associations between NAFLD and the outcome(s) of interest. The cumulative rate of 1-year all-cause re-hospitalizations was 46.7% (n = 99, mainly due to cardiac causes). Patients with NAFLD (n = 109; 51.4%) had remarkably higher 1-year all-cause and cardiac re-hospitalization rates compared with their counterparts without NAFLD. Both event rates were particularly increased in those with advanced NAFLD fibrosis. NAFLD was associated with a 5-fold increased risk of 1-year all-cause re-hospitalization (adjusted-hazard ratio 5.05, 95% confidence intervals 2.78-9.10, pacute HF.

    The introduction of digital planning programs has made it possible to place dental implants in preplanned positions and being immediately functionally loaded by using prefabricated prostheses. The aim of this multicenter study was to describe the 1-year results of digitally planned, immediately loaded edentulous maxillae. A total of 312 implants (Brånemark System, TiUnite RP, Nobel Biocare, Göteborg, Sweden) in 52 patients from eight Scandinavian clinics were digitally planned, surgically as well as prosthetically, by using the NobelGuide (Nobel Biocare AB, Göteborg, Sweden) and received prefabricated, immediately loaded fixed prosthetic constructions in the maxillae. Individual implant stability was manually tested at 1-year follow-up. All patients received a Procera Implant Bridge (Nobel Biocare AB); however, in two cases, the bridges were reconstructed due to misfit. In five patients, difficulties in getting the surgical guide completely in position, and in five patients, getting the prostheses completely seated, were noted. All but four patients fulfilled the 1-year follow-up. Two implants were lost during the study period, resulting in a cumulative survival rate of 99.4%. The mean marginal bone resorption from implant placement to the 1-year follow-up was 1.3 mm (SD 1.28). More than 2 mm of marginal resorption was noted in 19% of the implants at this instant. The most frequently reported complications during the first year were gingival hyperplasia and prosthesis-related problems (prosthesis screw loosening, occlusal fractures, and occlusal adjustments). The 1-year results in this multicenter are promising regarding implant and bridge stability; however, the study is planned to be running for at least 3 years.

    Articular cartilage repair remains a clinical and scientific challenge with increasing interest focused on the transplantation of chondrogenic cells. This study evaluated the repair response during a 1-year period after implantation of allogenic perichondrium cell polylactic acid composite grafts into 3.7 x 5 mm osteochondral defects drilled into the medial femoral condyles of 82 adult New Zealand White rabbits. The repair tissue was evaluated grossly, histologically, histomorphometrically, biochemically, and biomechanically at 6 weeks, 12 weeks, 6 months, and 1 year after implantation. After gross evaluation, cartilaginous material appeared to fill the defect in 70 experimental knees, for an overall repair frequency of 85%. The histomorphometric results and the histologic appearances were variable. None of the specimens were completely normal at 1 year. Only specimens with subchondral bone reformation displayed a definable cartilage appearing surface with chondrocytes surrounded by dense matrix. Subchondral bone reformation was inconsistent, reaching 50% at 1 year. Biochemically, the repair tissue matured during a 1-year period into a hyaline Type II collagen dominant tissue, whereas glycosaminoglycan content remained low at all time periods. The measured compressive properties of the repair tissue at 1 year were not significantly different from those of the contralateral knee that was not surgically treated. The treatment of osteochondral defects in the rabbit knee with allogenic perichondrium cell polylactic acid composite grafts yielded a high percentage of grossly successful repairs that showed inconsistent subchondral bone reformation. These results suggest that healthy subchondral bone is important to articular cartilage repair. They also highlight that a cartilaginous appearing tissue at gross inspection may not represent structurally normal articular cartilage.

    Previous studies persistently showed that functional dependence was associated with higher long-term (≥1 year) mortality of older patients hospitalised with community-acquired pneumonia (CAP). The importance of other factors was, however, not well reported. This study aimed to investigate the relative contributions of comorbidity, nutritional status and frailty to 1-year mortality. We prospectively recruited older patients, aged ≥65 years, hospitalised with CAP from October 2009 to September 2010 at the Prince of Wales Hospital, Hong Kong. Demographics, Charlson's Comorbidity Index, mid-arm circumference (MAC) and Clinical Frailty Scale (CFS) were recorded as baseline characteristics. The severity of pneumonia was evaluated by the CURB score (confusion, blood urea nitrogen, respiratory rate and low blood pressure). The surviving patients were followed for 1 year since discharge to monitor readmission for CAP and all-cause mortality. We entered the following variables into the multivariate Cox regression model to identify independent predictors of 1-year all-cause mortality: age, sex, residential status, MAC, Charlson's Comorbidity Index, CFS and readmission for CAP. The final cohort consisted of 428 patients who were discharged from hospital. Within 1 year after hospital discharge, all-cause mortality and readmission for CAP were 22.4% and 32.0% respectively. Independent predictors of 1-year mortality were male sex (hazard ratio (HR) = 1.57, 95% confidence interval (CI) = 1.02-2.48), severe under-nutrition (MAC ≤21 cm) (HR = 3.75, 95% CI = 1.66-8.46), frailty (CFS ≥5) (HR = 2.36, 95% CI = 1.29-4.27) and readmission for CAP (HR = 4.50, 95% CI = 2.82-7.17). Recurrent pneumonia may be a terminal life event of frail older people so that advance care planning should be considered in those with recurrent admission for pneumonia. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    Predicting survival outcomes after radiation therapy alone for metastatic disease of the spine is a challenging task that is important to guiding treatment decisions (e.g., determining dose fractionation and intensity). The New England Spinal Metastasis Score (NESMS) was recently introduced and validated in independent cohorts as a tool to predict 1-year survival following surgery for spinal metastases. This metric is composed of 3 factors: pre-operative albumin, ambulatory status, and modified Bauer score, with the total score ranging from 0 to 3. The purpose of this study is to assess the applicability of the NESMS model to predict 1-year survival among patients treated with radiation therapy alone for spinal metastases. This study is a retrospective analysis. This sample included 290 patients who underwent conventional radiation therapy alone for spinal metastases. Patients' NESMS scores (comprised of ambulatory status, pre-treatment serum albumin, and modified Bauer score) were assessed as well as their 1-year overall survival rates following radiation for metastatic disease of the spine. This study is a single-institution retrospective analysis of 290 patients treated with conventional radiation alone for spinal metastases from 2008 to 2013. The predictive value of the NESMS was assessed using multivariable logistic regression modeling, adjusted for potential confounding variables. This analysis indicated that patients with lower NESMS scores had higher rates of 1-year mortality. Multivariable analysis demonstrated a strong association between lower NESMS scores and lower rates of survival. The NESMS score is a simple prognostic scheme that requires clinical data that is often readily available and has been validated in independent cohorts of surgical patients. This study serves to validate the utility of the NESMS composite score to predict 1-year mortality in patients treated with radiation alone for spinal metastases. Copyright © 2017 Elsevier Inc. All

    AIMS/HYPOTHESIS: We investigated the survival rate of Danish diabetic patients with end-stage renal disease (ESRD) between 1990 and 2005 and evaluated possible predictors of survival rate. MATERIALS AND METHODS: Data were obtained from the Danish National Register on Dialysis and Transplantation...... diabetic: 5%, non-diabetic: 24%. The survival rate of transplanted patients with diabetes mellitus (types 1 and 2) compared with non-diabetic patients at 1 year was: 95 vs 93%, at 5 years: 80 vs 85% and at 10 years: 52 vs 71%. Among diabetic patients survival rate was better in transplanted than in waiting...... and from the Scandiatransplant database. Survival rates in different patient groups and association with age, sex, calendar time, waiting-list status and renal transplantation were evaluated using a multivariate Cox regression model. RESULTS: During the study period 8,421 patients (13% type 1 diabetic, 9...

  1. A prospective study of the 1-year incidence of fibromyalgia after acute whiplash injury.

    2015-01-01

    To measure the 1-year incidence of fibromyalgia in a cohort of acute whiplash-injured participants. Consecutive acute patients with whiplash were assessed via the 2010 Modified American College of Rheumatology (ACR) criteria for fibromyalgia at 3 months, 6 months and 1 year postinjury. At each of these follow-up points, participants were also examined for recovery from whiplash injury. Of an initial 268 participants, data on recovery was available for 264 participants during the 1-year follow-up period. At the 3-month follow-up, 62% (167/268) of participants reported recovery from their whiplash injuries. At 6 months, 76% (203/268) reported recovery, and at 1 year 82% (216/264) reported recovery. At 3 and 6 months follow-up none of the participants met the 2010 Modified ACR Criteria for fibromyalgia, but fibromyalgia criteria were met for 2 (of 264) seen at the 1-year follow-up, yielding a 1-year incidence of 0.8% (95% CI 0.1% to 3.0%). In the primary care setting, a significant proportion of patients with whiplash recover from whiplash injury at 1 year, and the incidence of fibromyalgia after acute whiplash injury is very low. The impression that fibromyalgia is common after whiplash injury may be due to the failure to exclude precollision fibromyalgia cases or due to referral bias of non-recovered patients.

    There is a lack of specific tools for risk stratification in patients who undergo MitraClip implantation. We aimed at combining preprocedural variables with prognostic impact into a specific risk model for the prediction of 1-year mortality in patients undergoing MitraClip implantation. A total of 311 consecutive patients who underwent MitraClip implantation were included. A lasso-penalized Cox-proportional hazard regression model was used to identify independent predictors of 1-year all-cause mortality. A nomogram (GRASP [Getting Reduction of mitrAl inSufficiency by Percutaneous clip implantation] nomogram) was obtained from the Cox model. Validation was performed using internal bootstrap resampling. Forty-two deaths occurred at 1-year follow-up. The Kaplan-Meier estimate of 1-year survival was 0.845 (95% confidence interval, 0.802 to 0.895). Four independent predictors of mortality (mean arterial blood pressure, hemoglobin natural log-transformed pro-brain natriuretic peptide levels, New York Heart Association class IV at presentation) were identified. At internal bootstrap resampling validation, the GRASP nomogram had good discrimination (area under receiver operating characteristic curve of 0.78, Somers' Dxy statistic of 0.53) and calibration (le Cessie-van Houwelingen-Copas-Hosmer p value of 0.780). Conversely, the discriminative ability of the EuroSCORE II (the European System for Cardiac Operative Risk Evaluation II) and the STS-PROM (the Society of Thoracic Surgeons Predicted Risk of Mortality score) was fairly modest with area under the curve values of 0.61 and 0.55, respectively. A treatment-specific risk model in patients who undergo MitraClip implantation may be useful for the stratification of mortality at 1 year. Further studies are needed to provide external validation and support the generalizability of the GRASP nomogram. Copyright © 2017 Elsevier Inc. All rights reserved.

    Studies comparing alternatives to ventriculoperitoneal (VP) shunting for treatment of hydrocephalus have often relied upon data from an earlier era that may not be representative of contemporary shunt survival outcomes. We sought to determine the shunt survival rate of our cohort and compare our results to previously published shunt survival and endoscopic third ventriculostomy (ETV) success rates. We identified 95 patients between 1 and 18 years of age, who underwent initial VP shunt placement between January 2001 and December 2010. Our study shows a shunt survival rate of 85% at 6 months and 79% at 2 years, for initial shunts in pediatric patients over 1 year of age in this cohort. The overall infection rate was 3%. This compares favorably with published success rates of ETV at similar time points as well as with the rate of infection. This suggests that ventricular shunting remains a viable alternative to ETV in the older child.

Organ and patient survival rates are important issues of interest post-transplantation. Aim: To determine the 1-year survival rate of renal transplant, we studied graft function, which is a predictor of survival, among those who received a kidney transplant in the time period between February 2012 and February 2013 at Montaserie Organ Transplantation Hospital. Materials and methods: This is a retrospective cohort study planned to determine patient and organ survival rates after kidney transplantation from living and deceased donors during a 1-year period. We also tried to clarify factors resulting in graft loss. Designated variables were collected using checklists and subsequently entered into SPSS software version 17 and analyzed using the Kaplan–Meier method and descriptive statistics.Results: From 173 patients included in the study, 67.1% (n=116 were female. The mean age of the recipients was 33±12.85 years. In the majority of cases, cause of end-stage renal disease was not clear (n=89, 51.44%. Urinary tract infection (23.1% was the commonest post-operative complication, followed by delayed graft function, which was diagnosed in 22 (12.7% recipients. Seventeen cases of graft rejection (9.8% were recorded and 4 (2.3% of these cases underwent nephrectomy that will be regarded as graft loss in this paper. Therefore, 1-year graft survival was 90.2%. Graft survival in cadaveric and live-donor recipients was 90.8% and 88.7%, respectively. As there was no mortality reported among graft recipients, 1-year patient survival rate

    Fatigue is common in end-stage renal disease patients receiving hemodialysis, reduces significantly their quality of life and is associated with all-cause and cardiac-related mortality. Unfortunately, little is known about the course of fatigue in patients on chronic hemodialysis. The Vitality Subscale of the SF-36 (SF-36 VS), Short-Form Health Survey, was administered to 45 patients in January (T1), June (T2) and November (T3) 2015. The score of the SF-36 VS did not differ significantly among T1, T2 and T3. Similarly, the 1-year course of the SF-36 Vitality Subscale score did not differ significantly among T1, T2 and T3 after stratification of patients for sex, age, BMI, IADL and Charlson. Between T1 and T2, 21 out of 45 patients (46.6%) changed their fatigue status: 8 fatigued patients became not-fatigued and 13 not-fatigued patients became fatigued. Between T2 and T3, 12 out of 45 (26.6%) patients changed their fatigue status: 5 fatigued patients became not-fatigued and 7 not-fatigued patients became fatigued. Between T1 and T3, 19 out of 45 patients (42.2%) changed their fatigue status: 6 fatigued patients became not-fatigued and 13 not-fatigued became fatigued. The present study is the first to identify variations in fatigue status among patients on chronic hemodialysis during 1-year course. These findings suggest to frequently assess the presence and severity of fatigue in patients on chronic hemodialysis.

    To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    To examine time trends of survival and mortality of ovarian cancer in the central and northern Denmark regions during the period 1998-2009. We conducted a cohort study including women recorded with a first-time diagnosis of ovarian cancer in the Danish National Registry of Patients (DNRP) between 1998 and 2009. Patients were followed for survival through the Danish Civil Registration System. We determined survival stratified by age, and used Cox proportional hazard regression analyses to obtain mortality rate ratios (MRRs) to assess changes over time. We found no improvement in overall ovarian cancer survival between 1998 and 2009. One-year survival was 71% in 1998-2000 and 68% in 2007-2009. Three-year survival declined from 48% in 1998-2000 to 46% in 2007-2009 (predicted), and 5-year survival declined from 40% in 1998-2000 to 37% in 2007-2009 (predicted). Compared with the period 1998-2000, the age-adjusted 1-year MRR was 1.05 (95% confidence interval CI: 0.86-1.28) for the period 2007-2009, and the predicted age-adjusted 3- and 5-year MRRs were 0.96 (95% CI: 0.83-1.12) and 0.99 (95% CI: 0.86-1.14), respectively. Results are not adjusted for tumor stage as this information was not available. We also observed a decline in the annual number of incident ovarian cancer patients during the study period, most pronounced in the youngest age group. The survival of ovarian cancer patients did not improve during the study period. This lack of improvement contrasts with the national cancer strategies implemented during this last decade, focusing on improving the survival of ovarian cancer patients.

    In general, voluminous data exists concerning burns in children, but the data focusing specially on children less than 1 year of age is sporadic. We therefore focused on examining the special features of burns in children less than 1 year of age. A retrospective study of all outpatient treated burn patients burns, representing 15% of all pediatric burns during the study period. The majority was male and aged 9-12 months. Most of the burns occurred at home, and in most cases a caregiver was present in the injury room. Scalds were the most common type of injury followed by contact burns. The most common source of scald was from cups containing hot drink, and the most common source of contact burn was hot stoves or oven doors. Special attention needs to be targeted toward the prevention of burns in children less than 1 year of age. The majority of the injuries could have been prevented with more vigilance.

    A wealth of data exists concerning paediatric burn epidemiology in general, but very little exists specifically in infants under 1 year of age, a special group in which mobility begins to develop. A retrospective study of all burn admissions of infants under 1 year old to The Welsh Centre for Burns from January 2003 to January 2006 was performed. During the 3-year period there were 104 new burns cases identified which represents 11.8% of all paediatric admissions. 63.5% (66) were treated as inpatients and 36.5% (38) treated as out-patients. Burns increased in frequency with increasing age and occurred mainly in the home. Scalds were the commonest type of burn in 65% (68) whilst the second most common was contact burns which accounted for 30% (31). The most common source of scald was from cups containing hot drinks (39%) and the most common source of contact burn was radiators/hot water pipes (30%). The mean TBSA was 2.3%, (range 0.5-38%). The frequency of burns in the under 1 year old population highlights a need for emphasis of burn prevention directed to this group. Special attention is needed to look at the specific aetiology of these burns. Starting points for prevention should address the number of burns surrounding hot drinks and bottle warming practices in the case of scalds and the dangers of household radiators and hot water pipes in the case of contact burns.

    Blastocystis spp. refer to a group of prevalent enteric protists found in humans and animals. Detection of Blastocystis spp. in fecal samples is often performed by clinicians with direct microscopy, which provides low sensitivity, or with culture and polymerase chain reaction testing, a method which is problematic when used with formalin-preserved stool samples. Prior study of Blastocystis and other enteric protists suggests that immunofluorescence antibody (IFA) stain could provide sensitivity and compatibility with formalin, but no information is available on the longevity of Blastocystis sp.'s surface antigens in formalin. We collected fecal samples from animals at a country fair held in the summer of 2009 in Oregon, USA. Samples were tested for the presence of Blastocystis infection using an IFA stain shortly after collection, and again after 1 year, with samples stored refrigerated at 4-8 °C. Most samples collected from steer, pigs, and goats were found to be Blastocystis positive. All fecal samples that were Blastocystis positive initially remained positive after 1 year. Blastocystis-negative samples remained negative. Minimal degradation was observed in stained slides. Blastocystis surface antigens detected by a polyclonal stain remained stable in formalin for a period of at least 1 year.

    Caregiver burden following stroke can have significant adverse health consequences for caregivers and threatens the recovery and successful rehabilitation of patients. Our objective was to identify patient factors that contribute to higher levels of caregiver burden. We prospectively studied patients admitted to our stroke unit over a 2-year period (2001-2002). Data were collected at baseline and at 1 year. Caregiver burden was measured at 1 year using the Relatives Stress Scale (completed by 155 caregivers) and the Bakas Caregiver Outcomes Scale (143 caregivers). Explanatory patient factors at baseline included sociodemographic status, stroke severity, stroke sub-type, functional disability (Barthel Index), functional handicap (Oxford Handicap Scale and Modified Rankin Scale), and cognitive status (orientation, clock drawing). At 1 year, mental health and health-related quality of life were assessed using the Fatigue Impact Scale, Geriatric Depression Scale, Global Deterioration Scale, and 36-item Short Form Health Survey. The baseline patient factors predictive of caregiver burden by multiple regression analysis were older patient age (Pstroke (Pcaregiver burden were older patient age (Pcaregivers at risk of caregiver burden. Patient demographic variables, cognitive function, and mental health status may further expose vulnerable caregivers. These factors should be considered in the development of strategies to offset caregiver burden.

    To investigate the efficacy and safety of a treatment strategy with latanoprost and dorzolamide in primary pediatric glaucoma patients partially responsive to surgery. Children with primary pediatric glaucoma having postsurgical untreated intraocular pressure (IOP) between 22 and 26 mm Hg were eligible. At baseline, patients were administered latanoprost once daily. Depending on IOP reduction, patients were allocated to continuation of latanoprost monotherapy or addition of dorzolamide twice daily, or switch to dorzolamide monotherapy 3 times daily. Patients in the dorzolamide monotherapy group with IOP reduction <20% from baseline were considered nonresponders. The primary endpoint was the percentage of responders. Study treatment continued for 3 years or until treatment failure. The present article reports the 1-year analysis results. A total of 35 patients (57 eyes) were analyzed. The mean age was 4.0 years (SD, 3.8). In total, 51 eyes were included in the efficacy analysis. In total, 43 eyes (84.3%; 95% confidence interval, 74.3-94.3) were considered responders: 29 on latanoprost monotherapy, 11 on the latanoprost/dorzolamide combination, and only 3 on the dorzolamide monotherapy. The efficacy of pharmacological treatment was inversely related to the age at the time of surgery. IOP reduction was 8.7 mm Hg (SD, 2.2) for latanoprost, 7.5 mm Hg (SD, 1.4) for the latanoprost/dorzolamide combination, and 8.7 mm Hg (SD, 2.1) for the dorzolamide monotherapy. Only mild or moderate local adverse events were noted. None of the patients was withdrawn due to adverse events. Latanoprost alone or in combination with dorzolamide is safe and highly effective in lowering IOP in children postsurgery. Nonresponders were mainly patients with early presentation of the disease.

    To evaluate the correlation between survival and tumour characteristics in 23 patients with chondrosarcoma. Records of 15 men and 8 women aged 14 to 66 (mean, 37) years who were diagnosed with primary (n=19) or secondary (n=4) chondrosarcoma of the axial skeleton (n=8), proximal extremity (n=9), or distal extremity (n=6) were reviewed. The tumour diameter was treatment only, and 5 declined treatment. The mean follow-up period for the 23 patients was 3.1 years (range, 3 weeks to 9 years). The 5-year survival rate was 43% overall, 83.3% for grade 1 tumours, 50% for grade 2 tumours, and 0% for grade 3 tumours. The median survival duration was 20 (95% confidence interval, 11-29) months. Two patients had local recurrence and 16 did not, and the 5 patients who declined treatment died. Survival correlated with Evans histological grading (p=0.004), the presence of metastasis at presentation (p=0.026) and local recurrence (p=0.004). The survival rate was lower in patients with higher Evan grading, metastasis, or local recurrence.

    The aims of this study of predominately racial/ethnic minority children in foster care (N=360, birth to 19 years old) in Los Angeles, CA were to examine the (1) prevalence of obesity (≥ 95 percentile) and overweight/obese (≥ 85 percentile) upon entrance to foster care (T1) and after 1 year in foster care (T2); (2) comparison of high weight categories to national statistics; (3) relationship of changes in weight status to age, reason for entry into foster care, and placement. Chi-square test and McNemar test comparing paired proportions were used to determine whether there were significant changes in the proportion of high weight categories between T1 and T2. Chi-square test or Fisher's exact test were used to evaluate the association between age, placement, and reason for foster care with the change in weight category. Changes in weight were categorized as (1) decreased in weight, (2) remained at overweight or obese, (3) increased in weight, or (4) remained normal. The proportion of obese and obese/overweight children between ages 2 and 5 were significantly lower at T2 than T1. There were no significant changes in the prevalence of obesity for the total population at T2. Children age 6 or older had a higher prevalence of obesity and overweight/obesity compared to national statistics. Of children at all ages, 64.7% of children of all ages entered foster care with a normal weight and stayed in the normal range during their first year in foster care, 12.2% decreased their weight, 15.4% remained overweight or obese, and 7.7% increased their weight. Age and parental substance use was related to change in weight category from T1 to T2. Children did not become more overweight or obese in foster care; however 28% of the children were obese or overweight upon entry into foster care. Children who are 6 years or older and obese upon entering foster care should be targeted for weight reduction. The pediatric community and child welfare system need to work together by

    Computed tomography (CT) urography is now used in the work-up of patients with hematuria. The dose of contrast medium and radiation varies considerably between the different CT protocols. To study the disease prevalence in a consecutive group of patients with hematuria undergoing CT urography with a low dose of contrast medium and radiation. From 1 April 2007 to 31 March 2008, using the Radiological Information System (RIS) as well as electronic patient records, demographic data, reason for referral, and diagnosis were obtained for all patients undergoing CT urography due to hematuria. The patients were followed for 3 years. A total of 771 patients had hematuria diagnosed at the time of referral. In 137 patients (18%), a tumor and / or a complex cyst was found in the urinary tract (renal, ureteral, or bladder), in 68 (9%) a calculi, in 118 (15%) other disease (i.e. infection or anomaly) was found. No abnormalities were found at CT urography in 455 (58%) of the patients with hematuria. Lesions were found more frequently in patients with visible hematuria than in patients with non-visible hematuria (48% vs. 29%). No malignant tumor or complex cyst was found in the kidneys or the ureters in patients with nonvisible hematuria. CT urography with its low dose of contrast medium and radiation is a useful diagnostic imaging test for investigating patients with hematuria. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Regional ozone pollution has become a major environmental concern in China, especially in densely populated and economically vibrant regions such as North China, including Beijing. To address this issue, surface ozone and its precursors (CO, NO, and NO2) from December 2012 to November 2013 at 12 sites in urban Beijing and 2 sites in suburban Beijing were analyzed. The annual average concentrations of O3, CO, NO, and NO2 in urban Beijing were 45.5 ± 50.2 μg m- 3, 1.5 ± 1.3 mg m- 3, 27.3 ± 42.7 μg m- 3, and 58.3 + 32.0 μg m- 3, respectively. The concentration of ozone was highest during summer, whereas concentrations of its precursors were highest during winter. Diurnal variations in ozone presented as a single-peak curve, with the peak appearing at about 15:00-16:00. Diurnal variations in most ozone precursors showed bimodal curves; the first peak appeared at about 08:00-09:00, and the second peak appeared at night. Hourly concentrations of ozone on the weekend were higher than those on weekdays between 11:00 and 24:00 in urban Beijing, which was suggestive of a significant weekend effect. This may be because NO inhibition on the weekend is weaker than that on weekdays during the ozone formation phase. Diurnal variations in OX (NO2 + O3) showed a single peak, which appeared at 15:00 or 16:00. The results of correlation analysis among OX, O3, and NO2 suggested that OX was mainly controlled by O3 during the day and by NO2 during the night throughout the year. OX was controlled by NO2 during both the day and night during winter due to the low concentration of O3. The regional transport of ozone along the upwind direction was found in a typical ozone pollution event in summer in Beijing.

    When the cause of an aborted cardiac arrest is unclear the initiation of therapy, counseling and family screening is challenging. We included 43 unselected, prospectively identified cardiac arrest survivors with or without a diagnosis. Family history for cardiac disease and supplemental electrocardiograms were evaluated for additional diagnostic information. 43 cardiac arrest survivors were included, 34 (79%) were male and the average age was 48years (range 23-64, SD 13.0). The most common etiologies identified in cardiac arrest survivors were ischemic heart disease (33%), cardiomyopathies (14%), miscellaneous (e.g. drug induced arrhythmias, coronary spasms) (12%) and channelopathies (5%). Family history of cardiac disease - even inheritable conditions - was not indicative of etiology in cardiac arrest survivors. Supplemental ECGs were abnormal in 10 of 43 patients; in the majority of these patients (7) no conclusive diagnosis was reached. In this study 16/43 (37%) of unselected, prospectively included cardiac arrest survivors remained without a diagnosis despite exhaustive investigations. We may extract additional diagnostic information from simple maneuvers during the recording of the electrocardiogram. We suggest that these ECG derived clues be investigated in future studies including genetic test results and data from relatives. Copyright © 2016 Elsevier Inc. All rights reserved.

    Although critical care physicians view obesity as an independent poor prognostic marker, growing evidence suggests that obesity is, instead, associated with improved mortality following ICU admission. However, this prior empirical work may be biased by preferential admission of obese patients to ICUs, and little is known about other patient-centered outcomes following critical illness. We sought to determine whether 1-year mortality, healthcare utilization, and functional outcomes following a severe sepsis hospitalization differ by body mass index. Observational cohort study. U.S. hospitals. We analyzed 1,404 severe sepsis hospitalizations (1999-2005) among Medicare beneficiaries enrolled in the nationally representative Health and Retirement Study, of which 597 (42.5%) were normal weight, 473 (33.7%) were overweight, and 334 (23.8%) were obese or severely obese, as assessed at their survey prior to acute illness. Underweight patients were excluded a priori. None. Using Medicare claims, we identified severe sepsis hospitalizations and measured inpatient healthcare facility use and calculated total and itemized Medicare spending in the year following hospital discharge. Using the National Death Index, we determined mortality. We ascertained pre- and postmorbid functional status from survey data. Patients with greater body mass indexes experienced lower 1-year mortality compared with nonobese patients, and there was a dose-response relationship such that obese (odds ratio = 0.59; 95% CI, 0.39-0.88) and severely obese patients (odds ratio = 0.46; 95% CI, 0.26-0.80) had the lowest mortality. Total days in a healthcare facility and Medicare expenditures were greater for obese patients (p obese survivors. Total function limitations following severe sepsis did not differ by body mass index category (p = 0.64). Obesity is associated with improved mortality among severe sepsis patients. Due to longer survival, obese sepsis survivors use more healthcare and result in higher

    The main purpose of this study is to investigate the changes in the signs of flatfoot of preschool-aged children in a 1-year follow-up study. This study performed follow-up on a total of 580 preschool-aged children (boys, 297 children; girls, 283 children) with a median age of 54 (range 36-71 months), and the average follow-up period was 11.8 months. This study used the Chippaux-Smirak index (CSI) of footprint as the assessment tool, and CSI > 62.70 % was used as the standard for determining whether preschool-aged children suffered from flatfoot. The results showed that the signs of flatfoot of preschool-aged children improved with increasing age. At the 1-year follow-up, the average CSI was 5.1 % lower, and the proportion of children with flatfoot was 14 % lower. The follow-up on the change in the signs of flatfoot showed that 37.6 % of the children originally with flatfoot had improved to normal, verifying that flatfoot indeed improves with increasing age. However, the results also showed that 9.9 % of the children who originally had normal feet had developed flatfoot with increasing age, which deserves subsequent investigation. The results of the follow-up also showed that children who were relatively younger, male, obese, and experiencing excessive joint laxity were more likely to experience the signs of flatfoot. The 1-year follow-up found that some preschool-aged children with flatfoot may develop normal feet, while children with normal feet may begin to experience the signs. Relevant factors affecting flatfoot in preschool-aged children continue to require further clarification.

    To analyze trends in health outcomes and the influence of risk factors in children under 1 year with acute bronchiolitis due to respiratory syncytial virus (RSV bronchiolitis). A risk-adjustment model for RSV bronchiolitis in-hospital mortality was also developed. Retrospective study of hospitalizations for RSV bronchiolitis in children aged bronchiolitis ranged between 6390 and 8637. The annual in-hospital mortality rate ranged from 120 (2004) to 69 (2012) per 100,000 hospitalizations and the mean length of stay decreased steadily from 6.5 to 5.2 days (p bronchiolitis were children without risk factors. The in-hospital mortality rate due to RSV bronchiolitis in children with risk factors was 18.8 times higher than non-high-risk children and, in adjusted analyses, the OR of in-hospital mortality due to RSV bronchiolitis was higher than that due to other causes. This study is a retrospective analysis, based on administrative data. It does not include data about pre- or in-hospital treatments, and has the limitations inherent in procedures for determining risk-adjusted mortality rates. Socioeconomic and environmental factors have not been considered in this study. RSV bronchiolitis is a leading cause of hospitalizations for infants under 1 year and has not shown incidence reduction over a 9 year period. Risk factors increase the in-hospital mortality risk and it is higher if the hospitalization cause is RSV bronchiolitis than any other reason.

    Full Text Available The purpose of this study was to identify predictors of grades of disability at least 1 year after stroke rehabilitation therapy. We recruited stroke patients from the inpatient rehabilitation department of a university hospital. The degree of disability was graded using the disability evaluation at least 1 year after stroke onset. Functional ability was evaluated using the Functional Independence Measure instrument on admission, on discharge from the inpatient rehabilitation program, and at the 6-month follow-up visit after discharge. Major sociodemographic, medical, and rehabilitative factors were also collected during the hospitalization period. Of the 109 patients surveyed, 64 (58.7% had severe or very severe grades of disability. The correlates of severe or very severe disability in logistic regression analyses were bilaterally affected (odds ratio, OR, 10.8, impaired orientation (OR, 3.6, and poorer functional ability at discharge (OR, 7.6. Based on the significant predictors identified, the logistic regression model correctly classified severe or very severe disability in 68.0% of subjects. The higher frequency of severe or very severe disability in this study may have been due to the relatively more severely affected stroke patient population in the inpatient rehabilitation service and the use of unique disability evaluation criteria. These results may provide information useful in planning continuous rehabilitation care and setting relevant socio-welfare policies for stroke victims.

    Enteroaggregative Escherichia coli (EAEC) has been associated with persistent diarrhea, reduced growth acceleration, and failure to thrive in children living in developing countries and with childhood diarrhea in general in industrialized countries. The clinical implications of an EAEC carrier-status in children in industrialized countries warrants clarification. To investigate the pathological significance of an EAEC carrier-state in the industrialized countries, we designed a 1-year dynamic cohort study and performed follow-up every second month, where the study participants submitted a stool sample and answered a questionnaire regarding gastrointestinal symptoms and exposures. Exposures included foreign travel, consumption of antibiotics, and contact with a diseased animal. In the capital area of Denmark, a total of 179 children aged 0–6 years were followed in a cohort study, in the period between 2009 and 2013. This is the first investigation of the incidence and pathological significance of EAEC in Danish children attending daycare facilities. Conventional microbiological detection of enteric pathogens was performed at Statens Serum Institute, Copenhagen, Denmark, and at Hvidovre Hospital, Copenhagen, Denmark. Parents completed questionnaires regarding gastrointestinal symptoms. The EAEC strains were further characterized by serotyping, phylogenetic analysis, and susceptibility testing. EAEC was detected in 25 (14%) of the children during the observational period of 1 year. One or more gastrointestinal symptoms were reported from 56% of the EAEC-positive children. Diarrhea was reported in six (24%) of the EAEC positive children, but no cases of weight loss, and general failure to thrive were observed. The EAEC strains detected comprised a large number of different serotypes, confirming the genetic heterogeneity of this pathotype. EAEC was highly prevalent (n = 25, 14%) in Danish children in daycare centers and was accompanied by gastrointestinal symptoms in

    There is an increasing body of literature reporting treatment failure of the currently recommended radical treatment of Plasmodium vivax infections. As P. vivax is the main malaria species outside the African continent, emerging tolerance to its radical treatment regime could have major consequences in countries like Peru, where 80% of malaria cases are due to P. vivax. Here we describe the results of a 1-year longitudinal follow up of 51 confirmed P. vivax patients living around Iquitos, Peruvian Amazon, and treated according to the Peruvian national guidelines. Each month a blood sample for microscopy and later genotyping was systematically collected. Recent exposure to infection was estimated by detecting antibodies against the P. vivax circumsporozoite protein (CSP) and all PCR confirmed P. vivax infections were genotyped with 16 polymorphic microsatellites. During a 1-year period, 84 recurrent infections, 22 positive also by microscopy, were identified, with a median survival time to first recurrent infection of 203 days. Most of them (71%) were asymptomatic; in 13 patients the infection persisted undetected by microscopy for several consecutive months. The genotype of mostly recurrent infections differed from that at day 0 while fewer differences were seen between the recurrent infections. The average expected heterozygosity was 0.56. There was strong linkage disequilibrium (I(A)(s) = 0.29, p<1.10(-4)) that remained also when analyzing only the unique haplotypes, suggesting common inbreeding. In Peru, the P. vivax recurrent infections were common and displayed a high turnover of parasite genotypes compared to day 0. Plasmodium vivax patients, even when treated according to the national guidelines, may still represent an important parasite reservoir that can maintain transmission. Any elimination effort should consider such a hidden reservoir.

    Diabetic patients have a high risk for cardiovascular events. The role of myocardial perfusion imaging was investigated in asymptomatic diabetic patients to evaluate short-term prognosis in a Japanese population. A total of 506 asymptomatic patients {>=}50 years of age who had carotid artery maximum intima-media thickness {>=}1.1 mm, urinary albumin excretion of {>=}30 mg/g creatinine, with additional criteria of abdominal obesity, low HDL cholesterol, high triglyceride level, and hypertension were enrolled and followed up over a 3-year period. Gated SPECT with stress-rest protocol was performed and analyzed by summed defect scores and QGS software. One-year cardiovascular events were analyzed. Myocardial ischemia was observed in 17% of patients, and abnormal perfusion findings of ischemia and/or scar were observed in 32% of patients. By the end of the 1-year follow-up, 33 (6.5%) cardiovascular events occurred including 6 all-cause deaths. Patients with summed stress score (SSS) >8 had a higher incidence of either death or cardiovascular events. Event-free survival rates for SSS 0-3, 4-8, 9-13, and {>=}14 were 0.96, 0.95, 0.82, and 0.76, respectively. Multivariate Cox regression analysis showed that significant variables were SSS, history of cerebrovascular accident, and electrocardiographic abnormality at rest. The 1-year interim summary showed that cardiovascular events were significantly higher in patients with SPECT abnormality, although hard cardiac event rate was relatively low. Targeted treatment strategy is required for asymptomatic but potentially high-risk diabetic patients. (orig.)

    The aim of this analysis is to examine the influence of gender differences on the outcome after transcatheter aortic valve implantation (TAVI) from a multicenter real-world registry in Germany (TAVI registry). The impact of gender differences on the clinical outcome after TAVI was examined in small studies with conflicting results. Consecutive patients (n = 1,432) undergoing TAVI in the period between January 2009 and June 2010 in Germany were evaluated. Differences in all-cause mortality were examined with Kaplan-Meier estimates and proportional hazards models. Women comprised 57.8 % of the cohort. The Edwards Sapien valve (18.5 %) and CoreValve (81.5 %) were used through the transfemoral (87.7 %), subclavian (3.0 %), transapical (8.6 %), or transaortic approach (0.7 %). At baseline, women had higher aortic gradients and were older. Men had more comorbidities: prior myocardial infarction, prior revascularization, prior coronary artery bypass surgery, peripheral arterial vascular disease and chronic obstructive pulmonary disease. Women had more periprocedural vascular complications in comparison to men (25.2 vs. 17.2 %, p < 0.001). There was no significant difference in mortality at 30-day follow-up (7.6 % for women vs. 8.6 % for men, p = 0.55). The adjusted HR for 1-year all-cause mortality favored women, HR 0.75 (95 % CI 0.57-0.98, p = 0.0346) with a mortality rate of 17.3 vs. 23.6 % for men. Female gender is associated with better 1-year survival after TAVI. These results suggest that TAVI could be the best treatment modality for elderly women with symptomatic severe aortic stenosis.

    The need for dietary counselling and nutritional support in oropharyngeal cancer patients is generally accepted. However, evidence for the effectiveness is sparse. The aim of this study was to describe dietary counselling, nutritional support, body weight and toxicity during and after treatment, and investigate the effect of pre-treatment body mass index (BMI) on survival in oropharyngeal cancer patients. A retrospective chart review was made in 276 oropharyngeal cancer patients treated with radiotherapy (RT). End points were dietary consultations, weight loss, toxicity, overall survival and disease-free survival. Almost all oropharyngeal cancer patients received dietary counselling (94%) and nutritional support (99%). Dietary counselling decreased sharply shortly after treatment to 38% at 1 year after treatment. Overall weight loss increased during the first year of follow-up and ranged from 3% at start of RT, until 11% at 1 year after RT. Overall survival was significantly longer for patients with a BMI above average (P=0.01). Acute dysphagia (P=0.001), mucositis (P=0.000) and toxicity grade 3 (P=0.002) were significantly more prevalent in patients who had lost 10% or more of their body weight. This study showed that patients continue to lose body weight during and until 1 year after treatment, despite nutrition support and frequent dietetic consultation. A BMI above average appears to increase survival time. Future studies, preferably randomized trials, are needed to compare standard dietary counselling with more intensive dietary counselling that consists of earlier and/or prolonged treatment.

    Although socioeconomic inequalities in cancer survival have been demonstrated both within and between countries, evidence on the variation of the inequalities over time past diagnosis is sparse. Furthermore, no comprehensive analysis of socioeconomic differences in cancer survival in Germany has been conducted. Therefore, we analyzed variations in cancer survival for patients diagnosed with one of the 25 most common cancer sites in 1997-2006 in ten population-based cancer registries in Germany (covering 32 million inhabitants). Patients were assigned a socioeconomic status according to the district of residence at diagnosis. Period analysis was used to derive 3-month, 5-year and conditional 1-year and 5-year age-standardized relative survival for 2002-2006 for each deprivation quintile in Germany. Relative survival of patients living in the most deprived district was compared to survival of patients living in all other districts by model-based period analysis. For 21 of 25 cancer sites, 5-year relative survival was lower in the most deprived districts than in all other districts combined. The median relative excess risk of death over the 25 cancer sites decreased from 1.24 in the first 3 months to 1.16 in the following 9 months to 1.08 in the following 4 years. Inequalities persisted after adjustment for stage. These major regional socioeconomic inequalities indicate a potential for improving cancer care and survival in Germany. Studies on individual-level patient data with access to treatment information should be conducted to examine the reasons for these socioeconomic inequalities in cancer survival in more detail. © 2013 UICC.

    Full Text Available Innovations currently represent a tool of maintaining the going concern of a business entity and its competitiveness. However, effects of innovations are not infinite and if an innovation should constantly preserve a life of business entity, it has to be a continual chain of innovations, i.e. continual process. Effective live of a single innovation is limited while the limitation is derived especially from industry. The paper provides the results of research on innovations effects in the financial performance of small and medium-sized enterprises in the Czech Republic. Objective of this paper is to determine the length and intensity of the effects of technical innovations in company’s financial performance. The economic effect of innovations has been measured at application of company’s gross production power while the Deviation Analysis has been applied for three years’ time series. Subsequently the Survival Analysis has been applied. The analyses are elaborated for three statistical samples of SMEs constructed in accordance to the industry. The results obtained show significant differences in innovations’ survival within these three samples of enterprises then. The results are quite specific for the industries, and are confronted and discussed with the results of authors’ former research on the issue.

    Background Long term mortality may be increased following traumatic brain injury (TBI); however the degree to which survival could be reduced is unknown. We aimed to model life expectancy following post-acute TBI to provide predictions of longevity and quantify differences in survivorship with the general population. Methods A population based retrospective cohort study using data from the Rochester Epidemiology Project (REP) was performed. A random sample of patients from Olmsted County, Minnesota with a confirmed TBI between 1987 and 2000 was identified and vital status determined in 2013. Parametric survival modelling was then used to develop a model to predict life expectancy following TBI conditional on age at injury. Survivorship following TBI was also compared with the general population and age and gender matched non-head injured REP controls. Results 769 patients were included in complete case analyses. Median follow up time was 16.1 years (IQR 9.0–20.4) with 120 deaths occurring in the cohort during the study period. Survival after acute TBI was well represented by a Gompertz distribution. Victims of TBI surviving for at least 6 months post-injury demonstrated a much higher ongoing mortality rate compared to the US general population and non-TBI controls (hazard ratio 1·47, 95% CI 1·15–1·87). US general population cohort life table data was used to update the Gompertz model’s shape and scale parameters to account for cohort effects and allow prediction of life expectancy in contemporary TBI. Conclusions Survivors of TBI have decreased life expectancy compared to the general population. This may be secondary to the head injury itself or result from patient characteristics associated with both the propensity for TBI and increased early mortality. Post-TBI life expectancy estimates may be useful to guide prognosis, in public health planning, for actuarial applications and in the extrapolation of outcomes for TBI economic models. PMID:27165161

    The present report is a retrospective analysis of the effect of intraoperative radiation therapy (IORT) for localized but unresectable pancreatic carcinoma. Thirteen of 30 patients treated by IORT in combination with external beam radiation therapy (EBRT) survived for more than one year. The longest survival period, attained by two patients, was 20 months. The 1, and 1.5-year survival rates were 46.5% and 20.8%, respectively, with a median survival of 11 months, whereas the 1-year survival rate was 0%, with a median survival of 6.2 months for the 16 patients treated by IORT alone (N=16). There was a statistically significant difference in survival rate between the two groups (p<0.01). Therefore, additional EBRT may be indispensable for prolongation of the survival period. Moreover, IORT conferred the palliative benefit of relief of pain in more than half of the patients with severe pain. In postmortem examination of seven patients who survived for more than one year, the tumors were replaced by fibrous and hyalinized tissue, as a result of the effect of IORT, and degeneration and necrosis of tumor cells were seen in the center of the tumor, while viable tumor cells remained in the periphery, spreading to the retroperitoneal tissues or neighboring organs. These histopathological findings are distinctive features of carcinoma of the pancreas treated by IORT. (author).

    During the last decade, high success rates have been reported for implants placed with immediate loading procedures, especially when bone quality and quantity provide good implant stability. In many of these studies, straight-walled implants with moderately rough surfaces were employed. Tapered implants are becoming increasingly more popular due to standardized drilling protocols and reports of high initial primary stability. The aim of the present prospective, single center clinical study was to evaluate surface topographical analysis and the clinical and radiographic outcomes of the NanoTite™ (BIOMET 3i, Palm Beach Gardens, FL, USA) Tapered Implant when used for immediate loading of fixed prostheses and single-tooth restorations. Forty-two patients who needed implant treatment and met admission criteria agreed to participate in the study and were consecutively enrolled. Surgical implant placement requirements consisted of a final torque of a least 30 Ncm prior to final seating and an implant stability quotient above 55. A total of 139 NanoTite Tapered implants (112 maxillary and 27 mandibular) were placed by one investigator, and the majority of these implants (n = 77/55%) were placed in posterior regions, and in soft bone (n = 90/65%). A total of 57 prosthetic constructions were evaluated consisting of 20 single-tooth restorations, 30 fixed partial dentures, and 7 complete, fixed maxillary restorations. Radiographs were taken at baseline and at 12 months of follow-up. Of the 139 study implants, one implant failure was declared. The overall cumulative survival rate at 1 year is 99.4%. Mean marginal bone resorption is 1.01 mm (SD 0.85) during the first year of function. Although limited to the short follow-up, immediate loading of NanoTite Tapered implants seems to be a viable option in implant rehabilitation, when insertion torque of at least 30 Ncm is achieved. Further studies are needed to authenticate the finding of this study. © 2012 Wiley

    Shorter sleep duration is linked to obesity, coronary artery disease, and diabetes. Whether sleep deprivation during the postpartum period affects maternal postpartum weight retention remains unknown. This study examined the association of sleep at 6 months postpartum with substantial postpartum weight retention (SPPWR), defined as 5 kg or more above pregravid weight at 1 year postpartum. The authors selected 940 participants in Project Viva who enrolled during early pregnancy from 1999 to 20...

    Objective To evaluate trends in survival among children with spina bifida by race/ethnicity and possible prognostic factors in 10 regions of the United States. Study design A retrospective cohort study was conducted of 5165 infants with spina bifida born during 1979-2003, identified by 10 birth defects registries in the United States. Survival probabilities and adjusted hazard ratios were estimated for race/ethnicity and other characteristics using the Cox proportional hazard model. Results During the study period, the 1-year survival probability among infants with spina bifida showed improvements for whites (from 88% to 96%), blacks (from 79% to 88%), and Hispanics (from 88% to 93%). The impact of race/ethnicity on survival varied by birth weight, which was the strongest predictor of survival through age 8. There was little racial/ethnic variation in survival among children born of very low birth weight. Among children born of low birth weight, the increased risk of mortality to Hispanics was approximately 4-6 times that of whites. The black-white disparity was greatest among children born of normal birth weight. Congenital heart defects did not affect the risk of mortality among very low birth weight children but increased the risk of mortality 4-fold among children born of normal birth weight. Conclusions The survival of infants born with spina bifida has improved; however, improvements in survival varied by race/ethnicity, and blacks and Hispanics continued to have poorer survival than whites in the most recent birth cohort from 1998-2002. Further studies are warranted to elucidate possible reasons for the observed differences in survival. PMID:22727874

    The aim of this study was to evaluate the predictive value of malnutrition-inflammation score (MIS) on short-term mortality and to identify the best cut-off point in the Turkish maintenance hemodialysis (MHD) population. A total of 100 patients on MHD were included in this prospective single-center study. Demographic, anthropometric, and biochemical data were obtained from all patients. The study population was followed up as a 12-month prospective cohort to evaluate mortality as the primary outcome. Median (IQR) age and HD vintage of 100 patients (M/F: 52/48) were 53 (39.5 - 67) years and 53.5 (11 - 104.7) months, respectively. Deceased patients (n = 7) had significantly older age (years) (50 (38.5 - 63.5) vs. 70 (62 - 82), respectively, p = 0.001), lower spKt/V (1.60 (1.40 - 1.79) vs. 1.35 (0.90 - 1.50), respectively, p = 0.002), lower triceps skinfold thickness (14 (10 - 19) vs. 9 (7 - 11), respectively, p = 0.021) and higher MIS (5 (4 - 7) vs. 10 (7 - 11), respectively, p = 0.013). In the ROC analysis, we found that the optimal cut-off value of MIS for predicting death was 6.5 with 85.7% sensitivity and 62.4% specificity (positive and negative predictive values were 0.6951 and 0.8136, respectively). Advanced age, low spKt/V, and high MIS were found to be predictors of mortality in multivariate logistic regression analysis. The 1-year mortality rate was significantly higher in MIS > 6.5 group compared to the MIS ≤ 6.5 group (14,3% (6/41) vs. 1.6% (1/59), respectively). Compared to MIS ≤ 6.5 group, 1 year survival time of the patients with MIS > 6.5 was found to be significantly lower (47.8 ± 0.16 vs. 43.6 ± 1.63 weeks, respectively, p (log-rank) = 0.012). MIS is a robust and independent predictor of short-term mortality in MHD patients. Patients with MIS > 6.5 had a significant risk, and additional risk factors associated with short-term mortality were advanced age and low spKt/V.

    The purpose of this study was to examine the effect of orthopedic forces on maxillary first molars' and maxillary central incisors' pulp chambers in children having rapid maxillary expansion as the only intervention compared with children having no orthodontic intervention by using cone-beam computed tomography images. In this prospective controlled clinical study, we evaluated 60 maxillary first molars and 60 maxillary central incisors from 30 children (18 boys, 12 girls) in the mixed dentition and during the pubertal growth period. The treated group had rapid maxillary expansion with the Haas expander, followed by 6 months of retention and 6 months of follow-up out of retention; the control group had no intervention during the study. Cone-beam computed tomography scans were taken initially and 1 year after the rapid maxillary expansion active phase. Initially, a 3-dimensional scrolling in all pulp chambers of the evaluated teeth was performed with Dolphin Imaging software (version 11.0; Dolphin Imaging & Management Solutions, Chatsworth, Calif) to describe the incidence of pulp-chamber calcifications. The dimensions of the pulp chambers of the molars and incisors were also investigated. Cross-sectional and longitudinal slices were used for each molar (coronal and axial slices) and incisor (sagittal and axial slices). The area (mm(2)) was obtained from 3 slices of each kind (6 measurements for each tooth). The results suggest that rapid maxillary expansion did not induce new pulp-chamber calcification. Also, it did not interfere in normal pulp-chamber dimension changes of the anchorage molars. The pulp chamber of the central incisors can be expected to be minimally wider 1 year after the therapy.

    The study aimed to assess the association between Apgar scores at 1 and 5 min after birth and seizures in infants less than 1 year old. We conducted a retrospective, observational, hospital-based study by utilising medical records from the Chung-Ang University Hospital admissions from January 2006 to May 2015 in order to identify infants less than 1 year old who had a history of seizures. Using electronic medical records, infants who were diagnosed with infantile seizures at the Chung-Ang University Hospital from January 2006 to May 2015 were included in the seizure group (n=93), and a control group consisting of 296 age-matched cases without a history of seizures was selected from a group of infants born at Chung-Ang University Hospital during the same study period. We found that Apgar scores were significant risk factors for infantile seizures. Apgar scores differed depending on gestational age and birth weight. We found strong associations between Apgar scores and infantile seizures in the full-term and the normal-birth weight groups (bodyweight ≥2.5 kg), regardless of delivery mode. The Apgar scores were inversely correlated with the EEG class, and only the 1-min Apgar scores were correlated with MRI findings. Low Apgar scores are significant perinatal risk factors for infantile seizures, especially in full-term and normal-birth weight infants, and have a strong negative linear relationship with EEG and brain MRI results in the seizure group.

    The aim of this prospective clinical trial was to assess clinical, radiological, and esthetic outcomes of immediate-loaded post-extractive implants after 1 year of follow-up. Twenty-four consecutive patients (15 females and nine males) with a mean age of 47.27 years (range 35-65) requiring single-tooth extraction in the maxillary or mandibular anterior or premolar areas were enrolled. Twenty-five NobelActive implants (Nobel Biocare, Göteborg, Sweden) were placed and loaded immediately after tooth extraction. The definitive prosthetic restoration was delivered 6 months later. Clinical parameters, marginal bone loss, as well as, pink and white esthetic scores (PES and WES) were evaluated at 3, 6, and 12 months after implant placement. After 12-month follow-up period, a success rate of 91.67% was reported: Two of the 25 initially placed implants were lost after 4 weeks due to lack of osseointegration. The mean marginal bone loss after 1-year follow-up was 0.383 (SD ± 0.749) at mesial site and 0.278 (SD ± 0.595) at distal site. No statistically significant changes in the full-mouth plaque score (FMPS) and in the full-mouth bleeding score (FMBS) were observed from baseline to 12 months. The mean total PES/WES was 17.13 ± 1.91 (range: 13-20). None of 23 implants had an overall score immediate placement and loading of a single NobelActive(™) implant in a fresh extraction socket may be considered a valuable and predictable option in terms of implant success as well as hard and soft tissues stability. © 2014 John Wiley & Sons A/S.

Although patient-controlled devices are frequently used in patients ≥6 years of age, alternative modes of analgesic delivery are needed in infants.Objective: To examine the safety and efficacy of nurse-controlled analgesia (NCA in neonates less than 1 year of age.Methods: Data from patients <1 year of age receiving NCA as ordered by the Acute Pain Service at our institution were collected over a 5-year period and reviewed retrospectively. The primary outcomes were activation of the institution’s Rapid Response Team (RRT or Code Blue, signifying severe adverse events. Pain score after NCA initiation was a secondary outcome.Results: Among 338 girls and 431 boys, the most common opioid used for NCA was fentanyl, followed by morphine and hydromorphone. There were 39 (5% cases involving RRT or Code Blue activation, of which only one (Code Blue was activated due to a complication of NCA (apnea. Multivariable logistic regression demonstrated morphine NCA to be associated with greater odds of RRT activation (OR=3.29, 95% CI=1.35, 8.03, P=0.009 compared to fentanyl NCA. There were no statistically significant differences in pain scores after NCA initiation across NCA agents.Conclusion: NCA is safe in neonates and infants, with comparable efficacy demonstrated for the three agents used. The elevated incidence of RRT activation in patients receiving morphine suggests caution in its use and consideration of alternative agents in this population.

    To document long-term survival in 1-year survivors of traumatic brain injury (TBI); to compare the use of the Disability Rating Scale (DRS) and FIM as factors in the estimation of survival probabilities; and to investigate the effect of time since injury and secular trends in mortality. Cohort study of 1-year survivors of TBI followed up to 20 years postinjury. Statistical methods include standardized mortality ratio, Kaplan-Meier survival curve, proportional hazards regression, and person-year logistic regression. Postdischarge from rehabilitation units. Population-based sample of persons (N=7228) who were admitted to a TBI Model Systems facility and survived at least 1 year postinjury. These persons contributed 32,505 person-years, with 537 deaths, over the 1989 to 2011 study period. Not applicable. Survival. Survival was poorer than that of the general population (standardized mortality ratio=2.1; 95% confidence interval, 1.9-2.3). Age, sex, and functional disability were significant risk factors for mortality (Pmodels had comparable predictive performance (C index: .80 vs .80; Akaike information criterion: 11,005 vs 11,015). Time since injury and current calendar year were not significant predictors of long-term survival (both P>.05). Long-term survival prognosis in TBI depends on age, sex, and disability. FIM and DRS are useful prognostic measures with comparable statistical performance. Age- and disability-specific mortality rates in TBI have not declined over the last 20 years.

    The aim of this study was to analyze long-term implant survival in the mandible after radiotherapy and radical surgery in oral cancer patients. Between 1990 and 2003, 71 patients (15 females, 56 males; average age 57.8 years, range 16-84.1 years) were treated with dental implants after radiochemotherapy and ablative surgery of oral cancer. Radiation therapy was delivered in daily fractions of 2 Gy given on 25 days (total dose of 50 Gy). Oral defects were reconstructed microsurgically with jejunal, iliac crest or radial forearm grafts. Thereafter 316 dental implants were placed in the non-irradiated residual bone (84; 27%), irradiated residual bone (154; 49%) or grafted bone (78; 25%) at various intervals (mean interval 1.41 (+/- 1.01) years, range 0.34-6.35 years). The mean follow-up time after implant insertion was 5.42 (+/- 3.21) years (range 0.3-13.61 years). The overall 2-, 3-, 5-, and 8-year survival rates of all implants were 95%, 94%, 91% and 75%. Forty-four implants were lost in 21 patients during the observation period. Irradiation of the mandibular bone showed significantly (P = 0.0028) lower implant survival compared with non-irradiated mandibular bone. The 8-year survival rate in the non-irradiated residual bone (two loss), irradiated residual bone (29 loss) or grafted bone (13 loss) were 95%, 72% and 54%, respectively. Time of implantation after irradiation showed no statistically significant influence. Implant brand, length or diameter or the incidence of resective surgery on the mandible and gender of patients had no statistically significant influence on implant survival. Radiation therapy with 50 Gy was significantly related to shorter implant survival in mandibular bone. Survival was lowest in grafted bone. Time of implant placement had no statistically significant influence on survival under the conditions of this study. Although implant survival is lower in irradiated mandibles, implants significantly facilitate prosthodontic treatment and

    Optimal treatment approach continues to remain a challenge for systemic light chain amyloidosis (AL). So far, Auto-SCT is the only modality associated with long-term survival. However, failure to show survival benefit in randomized study raises questions regarding its efficacy. We present a comparative outcome analysis of Auto-SCT to conventional therapies (CTR) in AL patients treated over a 14-year period at our institution. Out of the 145 AL amyloidosis patients, Auto-SCT was performed in 80 patients with 1-year non-relapse mortality rate of 12.5%. Novel agents were used as part of induction therapy in 56% of transplant recipients vs 46% of CTR patients. Hematological and organ responses were seen in 74.6% and 39% in the Auto-SCT arm vs 53% and 12% in the CTR arm, respectively. The projected 5-year survival for Auto-SCT vs CTR was 63% vs 38%, respectively. Landmark analysis of patients alive at 1-year after diagnosis showed improved 5-year OS of 72% with Auto-SCT vs 65% in the CTR arm. In the multivariate analysis, age Auto-SCT were associated with improved survival. In conclusion, Auto-SCT is associated with long-term survival for patients with AL amyloidosis.

    To explore repetition, service provision and service engagement following presentation of young people to emergency services with self-harm. 969 patients who presented to accident and emergency services after self-harm were followed up prospectively for a period of 1 year. Data on rates, method, clinical history, initial service provision, engagement and repetition (defined as re-presenting to emergency services with further self-harm) were gathered from comprehensive electronic records. Young people were less likely to repeat self-harm compared to those aged 25 and above. A psychiatric history and a history of childhood trauma were significant predictors of repetition. Young people were more likely to receive self-help as their initial service provision, and less likely to receive acute psychiatric care or a hospital admission. There were no differences in engagement with services between young people and those aged 25 and above. Younger individuals may be less vulnerable to repetition, and are less likely to represent to services with repeated self-harm. All young people who present with self-harm should be screened for mental illness and asked about childhood trauma. Whilst young people are less likely to be referred to psychiatric services, they do attend when referred. This may indicate missed opportunity for intervention.

    Previous studies with bilingual children have shown that the nature of their second-language instruction has an effect on the development of their cognitive abilities. The aim of this study was to determine whether children who acquire a second language in two different immersion programs for a period of 1year show advantages in executive functions and to examine how the amount of daily exposure affects executive functions. A group of Serbian-speaking second-grade children exposed to the second language for about 5h each day (high exposure group, HEG) and a low-exposure group (LEG) exposed to the second language for about 1.5h each day were compared with an age-matched control group (CG) of monolingual peers on working memory, inhibition, and shifting. Significant group differences were found for working memory, with the HEG performing better than the CG and LEG even after controlling for individual differences in terms of age and intelligence. The three groups did not differ in terms of inhibition and overall shifting abilities, although the control group had a marginally significant advantage on one of the two shifting tasks. Our findings extend previous research by demonstrating that the amount of daily exposure is a significant factor affecting executive functions in early immersion programs for second-language acquisition. In addition, they show that early intensive second-language acquisition can be advantageous for performance on tasks that require a higher level of executive control. Copyright © 2017 Elsevier Inc.

    Purpose: To evaluate changes in corneal topography and biomechanical properties after collagen cross-linking (CXL) for progressive keratoconus. Patients and Methods: Collagen cross-linking was performed on 97 eyes. We assessed uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Corneal topography indices were evaluated using placido disc topography, scanning slit anterior topography (Orbscan II), and rotating Scheimpflug topography (Pentacam). Specular microscopy and corneal biomechanics were evaluated. Results: A 1-year-follow-up results revealed that UCVA improved from 0.31 to 0.45 and BCVA changed from 0.78 to 0.84 (P corneal thickness decreased from 458.11 to 444.46 μm. Corneal volume decreased from 56.66 to 55.97 mm3 (P Corneal hysteresis changed from 8.18 to 8.36 (P = 0.552) and corneal resistance factor increased from 6.98 to 7.21 (P = 0.202), so these changes were not significant. Conclusion: Visual acuity and K values improved after CXL. In spite of the nonsignificant increase in endothelial cell count and increase in the CV, CLX seems to be a safe treatment for keratoconus. Further studies with larger sample sizes and longer follow-up periods are recommended. PMID:25949080

    Prospective longitudinal research is needed to examine associations between bullying behaviors and trajectories of suicidal ideation and behavior and overall functional impairment. The specific aims of the present study are to: (1) characterize differences in baseline functioning between acutely suicidal adolescents who are classified into bullying perpetrator and non-bully groups and (2) examine the 1-year trajectories of these two groups of adolescents. Participants were 433 psychiatrically hospitalized suicidal adolescents (72% female), ages 13 to 17 years. Participants reported suicidal ideation, depression, anxiety, substance use, adaptive functioning, and bullying behavior. Six items from the Youth Self-Report were used to classify adolescents into bullying perpetrator (n = 54) and non-bully (n = 379) groups. Follow-up assessments were conducted at 6 weeks, 3 months, 6 months, and 12 months. At hospitalization, adolescents in the bully group reported significantly higher levels of suicidal ideation, substance use, and functional impairment. Suicidal ideation differences remitted at six weeks. The elevated functional impairment of the bullying perpetrator group persisted across the 12-month period. Adolescents who met bullying perpetrator group criteria were characterized by more severe suicidal ideation and higher levels of proximal risk factors for suicide. Bullying behavior was not stable over time but was associated with elevated suicide risk when present. These findings highlight the importance of specifically assessing for and targeting bullying behavior at multiple time points when treating suicidal adolescents.

    Full Text Available Objective: To evaluate the preliminary results of the surgical treatment through minimally invasive fixation technique in patients with thoracolumbar spinal fractures. Methods: Retrospective study of 17 patients with fractures of thoracolumbar vertebrae who underwent surgery with percutaneous fixation in the period of 2009 to 2011. The clinical evaluation of the results was performed using the SF-36 and Oswestry questionnaires. The radiographic parameters evaluated were: fracture classification according to Magerl's criteria, wedge angle of the fractured vertebrae and bisegmental Cobb angle. These measurements were made in the preoperative, immediate postoperative and 1 year after surgery. Other data such as associated injuries, neurological deficit, post-surgical infection, loosening and breakage of implants were also considered. Results: The data revealed average scores above 80% in all domains of the SF-36 questionnaire while in Oswestry Questionnaire, 79% of patients had minimal or absent physical limitations with a mean score of 12.4±11.89%. The average Cobb angle for preoperative kyphosis was 5.53º±13.80o, 2.18º±13.38o in the early postoperative period and 5.26º±13.95o one year after surgery. The average correction obtained after surgery was 3.35º and the average correction loss was 3.19º. No complications such as post-surgical infection, permanent neurological deficits and implant loosening and breakage were observed. Conclusion: The surgical treatment of fractures of thoracolumbar vertebrae using a minimally invasive technique provides satisfactory clinical and radiographic results with low complication rates.

    The seasonal and spatial characteristics of PM2.5 and its chemical composition in the Mediterranean Basin have been studied over a 1-year period (2011-2012) in five European Mediterranean cities: Barcelona (BCN), Marseille (MRS), Genoa (GEN), Venice (VEN), and Thessaloniki (THE). During the year under study, PM10 annual mean concentration ranged from 23 to 46 μg m- 3, while the respective PM2.5 ranged from 14 to 37 μg m- 3, with the highest concentrations observed in THE and VEN. Both cities presented an elevated number of exceedances of the PM10 daily limit value, as 32% and 20% of the days exceeded 50 μg m- 3, respectively. Similarly, exceedances of the WHO guidelines for daily PM2.5 concentrations (25 μg m- 3) were also more frequent in THE with 78% of the days during the period, followed by VEN with 39%. The lowest PM levels were measured in GEN. PM2.5 exhibited significant seasonal variability, with much higher winter concentrations for VEN and MRS, in fall for THE and in spring for BCN. PM2.5 chemical composition was markedly different even for similar PM2.5 levels. On annual average, PM2.5 was dominated by OM except in THE. OM contribution was higher in Marseille (42%), while mineral matter was the most abundant constituent in THE (32%). Moreover, PM2.5 relative mean composition during pollution episodes (PM2.5 > 25 μg m- 3) as well as the origins of the exceedances were also investigated. Results outline mainly the effect of NO3- being the most important driver and highlight the non-negligible impact of atmospheric mixing and aging processes during pollution episodes.

    Does foreign ownership enhance or decrease a firm's chances of survival? Over the 100 year period 1895-2001 this paper compares the survival of foreign subsidiaries in Denmark to a control sample matched by industry and firm size. We find that foreign-owned companies have higher survival...... probability. On average exit risk for domestic companies is 2.3 times higher than for foreign companies. First movers like Siemens, Philips, Kodak, Ford, GM or Goodyear have been active in the country for almost a century. Relative foreign survival increases with company age. However, the foreign survival...

    The survival of Salmonella enterica Enteritidis PT 30 or five-strain cocktails of S. enterica, Escherichia coli O157:H7, and Listeria monocytogenes was evaluated on inshell walnuts during storage. Inshell walnuts were separately inoculated with an aqueous preparation of the pathogens at levels of 10 to 4 log CFU/nut, dried for 24 h, and then stored at either 4 °C or ambient conditions (23-25 °C, 25-35% relative humidity) for 3 weeks to more than 1 year. During the initial 24-h drying period, bacterial levels declined by 0.7 to 2.4 log CFU/nut. After the inoculum dried, further declines of approximately 0.1 log CFU/nut per month of Salmonella Enteritidis PT 30 levels were observed on inshell walnuts stored at 4 °C; at ambient conditions the rates of decline ranged from 0.55 to 2.5 log CFU/nut per month. Rates of decline were generally greater during the first few weeks of storage, particularly at lower inoculum levels. The survival of the five-strain cocktails inoculated at very low levels (under 400 CFU/nut) was determined during storage at ambient conditions. The pathogens could be recovered by either enumeration or enrichment from most samples throughout the 3-month storage period; reductions in bacterial levels from the beginning to end of storage were 0.7, 0.2, and 2.3 log CFU/nut for Salmonella, E. coli O157:H7, and L. monocytogenes, respectively. For 6% of all nut samples (14 of 234 samples), pathogens were isolated from the second but not first 24-h enrichment, suggesting that bacterial cells were viable but not easily culturable. Salmonella-inoculated walnuts were exposed for 2 min to water or a 3% solution of sodium hypochlorite (to mimic commercial brightening) either 24 h or 7 days after inoculation; treated nuts were dried for 24h and held at ambient conditions. Salmonella levels were reduced by less than 0.5 log or 2.4 to 2.6 log CFU/nut on water- or chlorine- treated walnuts, respectively, regardless of postinoculation treatment time. Additional

  3. Animal evolution and atmospheric pO2: is there a link between gradual animal adaptation to terrain elevation due to Ural orogeny and survival of subsequent hypoxic periods?

    Considering evolution of terrestrial animals as something happening only on flat continental plains seems wrong. Many mountains have arisen and disappeared over the geologic time scale, so in all periods some areas of high altitude existed, with reduced oxygen pressure (pO2) and increased aridity. During orogeny, animal species of the raising terrain can slowly adapt to reduced oxygen levels.This review proposes that animal evolution was often driven by atmospheric oxygen availability. Transitions of insect ancestors and amphibians out of water are here interpreted as events forced by the lack of oxygen in shallow and warm water during Devonian. Hyperoxia during early Carboniferous allowed giant insects to be predators of lowlands, forcing small amphibians to move to higher terrains, unsuitable to large insects due to reduced pO2. In arid mountainous habitats, ascended animals evolved in early reptiles with more efficient lungs and improved circulation. Animals with alveolar lungs became the mammalian ancestors, while those with respiratory duct lungs developed in archosaurs. In this interpretation, limb precursors of wings and pneumatised bones might have been adaptations for moving on steep slopes.Ural mountains have risen to an estimated height of 3000 m between 318 and 251 Mya. The earliest archosaurs have been found on the European Ural side, estimated 275 Myr old. It is proposed that Ural orogeny slowly elevated several highland habitats within the modern Ural region to heights above 2500 m. Since this process took near 60 Myr, animals in these habitats fully to adapted to hypoxia.The protracted P-Tr hypoxic extinction event killed many aquatic and terrestrial animals. Devastated lowland areas were repopulated by mammaliaformes that came down from mountainous areas. Archosaurs were better adapted to very low pO2, so they were forced to descend to the sea level later when the lack of oxygen became severe. During the Triassic period, when the relative content

    Peroral endoscopic myotomy (POEM) is a promising therapy in the treatment of achalasia. The study was designed to report outcomes, including quality of life, in patients with at least 1-year follow-up. Patients from an institutional review board-approved protocol underwent POEM and were followed prospectively. Health-related quality of life was measured preoperatively and 1 year post-operatively using Short Form-36 Health Survey version 2 (SF-36v2). Comparisons were made with patients from a prospective database who underwent laparoscopic Heller myotomy (LHM) over the same period. Paired t tests were used to analyze all normally distributed data, while Wilcoxon signed-rank tests were used to analyze SF-36 data, as it does not follow a normal distribution. We analyzed 41 consecutive POEM patients with at least 1-year follow-up. Significant improvements in quality of life between baseline and 1 year were found in role limitations due to physical health (81.8 ± 25.8 vs. 65.9 ± 31.6, p = 0.01) and social functioning (83 ± 19.1 vs. 64.6 ± 31.3, p = 0.01). When compared to 24 patients who underwent LHM, there was no difference in average Eckardt scores (0.9 ± 1.6 vs. 1.0 ± 1.3, p > 0.05) or incidence of PPI use (43.5 vs. 47.5 %, p = 0.71). However, when looking at just type III patients, POEM patients had a higher remission rate (100 vs. 62.5 %) and significantly lower post-operative Eckardt scores at 1 year (1.1 vs. 3.1, p POEM was 18.6 cm (±6.9) compared to 10.3 cm (±1.0) in LHM patients (p POEM provides a significant quality of life benefit at 1 year while having similar relief of dysphagia and post-operative PPI use compared to LHM. Type III achalasia patients may have better outcomes with POEM compared to LHM.

    It is unclear whether, and to what extent, the striking cardiac morphological manifestations of endurance athletes are a result of exercise training or a genetically determined characteristic of talented athletes. We hypothesized that prolonged and intensive endurance training in previously sedentary healthy young individuals could induce cardiac remodeling similar to that observed cross-sectionally in elite endurance athletes. Twelve previously sedentary subjects (aged 29±6 years; 7 men and 5 women) trained progressively and intensively for 12 months such that they could compete in a marathon. Magnetic resonance images for assessment of right and left ventricular mass and volumes were obtained at baseline and after 3, 6, 9, and 12 months of training. Maximum oxygen uptake ( max) and cardiac output at rest and during exercise (C2H2 rebreathing) were measured at the same time periods. Pulmonary artery catheterization was performed before and after 1 year of training, and pressure-volume and Starling curves were constructed during decreases (lower body negative pressure) and increases (saline infusion) in cardiac volume. Mean max rose from 40.3±1.6 to 48.7±2.5 mL/kg per minute after 1 year (Ptraining duration and intensity and reached levels similar to those observed in elite endurance athletes. In contrast, left ventricular volume did not change significantly until 6 months of training, although right ventricular volume increased progressively from the outset; Starling and pressure-volume curves approached but did not match those of elite athletes. One year of prolonged and intensive endurance training leads to cardiac morphological adaptations in previously sedentary young subjects similar to those observed in elite endurance athletes; however, it is not sufficient to achieve similar levels of cardiac compliance and performance. Contrary to conventional thinking, the left ventricle responds to exercise with initial concentric but not eccentric remodeling during

    We devised a new system called "Educational Guidance" (E-Guide) for nutritional education based on self-efficacy. The present study aimed to examine the effects of E-Guide use on glycemic control among patients with type 2 diabetes. We carried out an interventional and observational study that included 74 patients with type 2 diabetes. The extent of glycemic control in the 39 patients who received guidance through the E-Guide (E-Guide group) was compared with that of 35 patients who received conventional nutritional guidance (control group). We carried out a 1-year follow-up survey (subanalysis) based on the electronic health records of 18 patients from the E-guide group and 19 patients from the control group. These patients continued treatment at Hikone Municipal Hospital, Hikone, Shiga, Japan. Changes in glycated hemoglobin levels, body mass index and medication dose were examined from time of enrollment to the end of the 1-year intervention, and during the 1-year follow-up. Decreases in glycated hemoglobin levels were more pronounced in the E-Guide group than in the control group during the intervention period (P Intervention based on our "E-Guide" is more useful and powerful than the conventional methods for glycemic control and self-care behavior among patients with type 2 diabetes in Japan. © 2016 The Authors.

    We aimed to evaluate congestive heart failure (CHF) multidisciplinary disease management program (DMProg) impact on mortality, readmission rates, length of stay (LOS), and gender health characteristics. This was a quasi-observational, pre- and post-trial with a parallel nonequivalent group. We enrolled 174 inpatients having CHF with reduced ejection fraction and New York Heart Association (NYHA) Class II-IV, and a total of 197 hospital admissions. A comparative follow-up was performed from 15 December 2014 to 15 December 2015. Among 197 consecutive hospital admissions, 76 (39%) were included in the preintervention or usual care group and 121 (61%) were assigned to the postintervention group. After 1 year, in comparison with the preintervention group, the postintervention group had shorter average LOS in days (7.6 days vs. 11.1 days, p < 0.002), lower 1-year readmission rate (36% vs. 57%, p < 0.003), and lower in-house mortality (1.6% vs. 7.8%, p = 0.03), but similar baseline mortality scores (38.2 vs. 38.6, p = 0.7), 30-day and 90-day readmission rates (15% vs. 18.3%, p = 0.62 and 27.6% vs. 30%, p = 0.65), and 30-day readmission risk score (24.9% vs. 26.2%, p = 0.09). By regression analysis, the DMProg intervention was an independent factor for 1-year readmission reduction (p = 0.001). Kaplan-Meier survival analysis favored the postintervention group (log-rank, p < 0.001). DMProg significantly decreased 1-year readmission rates, LOS, and in-house mortality.

    This study examined the changes in eating disorder (ED) status over 1 year and identified risk factors for EDs among female dance students. In 2003, all students enrolled in each of the nation's 12 high schools with gifted dance programs participated in a two-phase survey. The same participants were invited to take part in a follow-up survey 1 year later. In all, 583 persons completed the phase 1 questionnaire survey, and 245 persons completed interviews twice at baseline and follow-up. Thirty-five females had a newly developed ED, and less than half of the ED cases found at baseline had recovered at follow-up. Being a grade 12 student carried a reduced risk of EDs, whereas higher baseline scores on the Bulimic Investigatory Test Edinburgh (BITE) increased risks of developing an ED after 1 year. A 10-item BITE questionnaire validly identified girl dance students who would develop EDs later in high school. EDs were more commonly developed during middle adolescence, and we suggest that prevention work against EDs begin in this period among the dance student population. The brief screening questionnaire might help detect intervention targets of a prevention program among adolescent dance students. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Our objective was to investigate the factors predicting the survival of patients on the waiting list for lung transplantation (LT) during the waiting period, with a special emphasis on the physical activity level. The study included 70 patients with end-stage pulmonary disease who were on the waiting list for LT at Kyoto University Hospital. We examined the association between the baseline characteristics, including the body mass index and body composition, serum albumin, serum C-reactive protein (CRP), steroid administration, physical activity level (calculated by the food frequency questionnaire) and survival during the waiting period using Kaplan-Meier curves and Cox proportional hazard regression models. A physical activity level of ≤1.2 was correlated with significantly decreased survival (1-year survival: 68 vs. 90.9%, p = 0.0089), with a hazard ratio (HR) of 2.24 (95% confidence interval (CI) 1.22-4.19, p = 0.0001). Hypo-albumin (HR 2.024, 95% CI 1.339-6.009, p = 0.004), a high level of CRP (HR 2.551, CI 1.229-4.892, p = 0.02), and the administration of steroids (HR 2.258, CI 1.907-5.032, p = 0.024) were also significant predictors of survival. Low levels of physical activity during the waiting period for LT led to decreased survival times among LT candidates.

    In academic institutions, residents make substantial contributions to clinical productivity. However, billing cannot be generated unless there is direct attending physician supervision of these services. The purpose of this study was to quantify clinical services provided by residents at a large academic medical center. The authors performed a review of all consultations to the plastic surgery service between January 1 and December 31, 2014. Documentation was reviewed and hypothetical billing for services was generated using American Medical Association Current Procedural Terminology and evaluation and management codes. A total of 2367 consultations were reviewed during the 1-year study period. Residents provided services under indirect supervision for the majority of consultations [n = 1940 (81.9 percent)]. If these services had been billed, evaluation and management would have resulted in 6970 physician work relative value units. More than half of the encounters (52.0 percent) involved at least one procedure, resulting in an additional 3316 work relative value units from 1339 Current Procedural Terminology codes. Using a conservative estimate (2014 Medicare reimbursement rates), charges from these services would total $368,496. The plastic surgery consultation service is a potential source of uncaptured revenue for training programs using indirect supervision of residents. Greater than 10,000 work relative value units could have been generated from resident clinical services, which is considerably more than the national average productivity of a full-time, academic plastic surgeon. Capturing a portion of this revenue stream could improve the fiscal balance of training programs and improve the cost-effective use of resident productivity.

    Full Text Available Intensive measurements of submicron aerosol particles and their chemical composition were performed with an Aerosol Chemical Speciation Monitor (ACSM at the Cabauw Experimental Site for Atmospheric Research (CESAR in Cabauw, the Netherlands, sampling at 5 m height above ground. The campaign lasted nearly 1 year from July 2012 to June 2013 as part of the EU-FP7-ACTRIS project (Q-ACSM Network. Including equivalent black carbon an average particulate mass concentration of 9.50 µg m−3 was obtained during the whole campaign with dominant contributions from ammonium nitrate (45 %, organic aerosol (OA, 29 %, and ammonium sulfate (19 %. There were 12 exceedances of the World Health Organization (WHO PM2.5 daily mean limit (25 µg m−3 observed at this rural site using PM1 instrumentation only. Ammonium nitrate and OA represented the largest contributors to total particulate matter during periods of exceedance. Source apportionment of OA was performed season-wise by positive matrix factorization (PMF using the multilinear engine 2 (ME-2 controlled via the source finder (SoFi. Primary organic aerosols were attributed mainly to traffic (8–16 % contribution to total OA, averaged season-wise and biomass burning (0–23 %. Secondary organic aerosols (SOAs, 61–84 % dominated the organic fraction during the whole campaign, particularly on days with high mass loadings. A SOA factor which is attributed to humic-like substances (HULIS was identified as a highly oxidized background aerosol in Cabauw. This shows the importance of atmospheric aging processes for aerosol concentration at this rural site. Due to the large secondary fraction, the reduction of particulate mass at this rural site is challenging on a local scale.

    This pilot study aimed to describe the sleep of partners and other family caregivers prior to and in the first year after a hospice patient's death. The study also evaluated the feasibility of the study protocol and determined the effect sizes in preparation for a full-scale study. The pilot study used a longitudinal, descriptive and comparative design. Participants included primary family caregivers of patients admitted to a hospice in Oslo, Norway. Caregiver sleep was measured subjectively with the Pittsburgh Sleep Quality Index (PSQI) and objectively using wrist actigraphy for 4 nights and 3 days at three different times: during the hospice stay, and at 6 and 12 months after the patient's death. 16 family caregivers (10 partners and 6 other family members) completed the 1-year study protocol. Overall, sleep quality and quantity were stable over time and at each assessment, approximately half of the sample had poor sleep quality, both by self-report and objective measures. However, the sleep trajectories differed significantly over time, with older caregivers (≥ 65 years) having significantly longer sleep durations than younger caregivers (sleep quality also differed over time depending on the caregiver's relationship to the patient, with partner caregivers having significantly worse sleep quality than other family caregivers. Caring for a dying family member is known to interfere with sleep, yet little is known about bereaved caregivers. The results of this pilot study demonstrate the feasibility of the longitudinal study protocol and indicate that sleep problems are common for caregivers and continue into the bereavement period, particularly for partner caregivers. The caregiver's relationship to the patient may be an important factor to consider in future studies. Published by the BMJ Publishing Group Limited.

    Reducing breast cancer incidence and achieving equity in breast cancer outcomes remains a priority for public health practitioners, health care providers, policy makers, and health advocates. Monitoring breast cancer survival can help evaluate the effectiveness of health services, quantify inequities in outcomes between states or population subgroups, and inform efforts to improve the effectiveness of cancer management and treatment. We analyzed breast cancer survival using individual patient records from 37 statewide registries that participated in the CONCORD-2 study, covering approximately 80% of the US population. Females were diagnosed between 2001 and 2009 and were followed through December 31, 2009. Age-standardized net survival at 1 year, 3 years, and 5 years after diagnosis was estimated by state, race (white, black), stage at diagnosis, and calendar period (2001-2003 and 2004-2009). Overall, 5-year breast cancer net survival was very high (88.2%). Survival remained remarkably high from 2001 through 2009. Between 2001 and 2003, survival was 89.1% for white females and 76.9% for black females. Between 2004 and 2009, survival was 89.6% for white females and 78.4% for black females. Breast cancer survival was more than 10 percentage points lower for black females than for white females, and this difference persisted over time. Reducing racial disparities in survival remains a challenge that requires broad, coordinated efforts at the federal, state, and local levels. Monitoring trends in breast cancer survival can highlight populations in need of improved cancer management and treatment. Cancer 2017;123:5100-18. Published 2017.

    Full Text Available Background: Transarterial chemoembolization is the preferred treatment for unresectable, intermediate-stage hepatocellular carcinoma. Survival after transarterial chemoembolization can be highly variable. The purpose of this study is to identify the factors that predict overall survival of patients with unresectable hepatocellular carcinoma who undergo transarterial chemoembolization as the initial therapy. Methods:We included patients who underwent transarterial chemoembolization from 2007 to 2012 in this study. Patient’s age, gender, cause of cirrhosis, Child-Turcotte-Pugh score, model of end-stage liver disease score, Cancer of the Liver Italian Program score, Okuda stage, alpha- fetoprotein level, site, size and number of tumors were recorded. Radiological response to transarterial chemoembolization was assessed by computerized tomography scan at 1 and 3 months after the procedure. Repeat sessions of transarterial chemoembolization were performed according to the response. We performed survival assessment and all patients were assessed for survival at the last follow-up. Results: Included in this study were 71 patients of whom there were 57 (80.3 % males, with a mean age of 51.9±12.1 years (range: 18-76 years. The mean follow-up period was 12.5±10.7 months. A total of 31 (43.7% patients had only one session of transarterial chemoembolization, 17 (23.9% underwent 2 and 11 (15.5% had 3 or more sessions. On univariate analysis, significant factors that predicted survival included serum bilirubin (P=0.02, esophageal varices (P=0.002, Cancer of the Liver Italian Program score (P=0.003, tumor size (P=0.005, >3 sessions of transarterial chemoembolization (P=0.006 and patient's age (P=0.001. Cox regression analysis showed that tumor size of 1 transarterial chemoembolization session (P=0.004 were associated with better survival. Conclusion: Our study demonstrates that survival after transarterial chemoem- bolization is predicted by tumor size

    Assessment of progress in cancer control at the population level is increasingly important. Population-based survival trends provide a key insight into the overall effectiveness of the health system, alongside trends in incidence and mortality. For this purpose, we aimed to provide a unique measure of cancer survival. In this observational study, we analysed trends in survival with population-based data for 7·2 million adults diagnosed with a first, primary, invasive malignancy in England and Wales during 1971-2011 and followed up to the end of 2012. We constructed a survival index for all cancers combined using data from the National Cancer Registry and the Welsh Cancer Intelligence and Surveillance Unit. The index is designed to be independent of changes in the age distribution of patients with cancer and of changes in the proportion of lethal cancers in each sex. We analysed trends in the cancer survival index at 1, 5, and 10 years after diagnosis for the selected periods 1971-72, 1980-81, 1990-91, 2000-01, 2005-06, and 2010-11. We also estimated trends in age-sex-adjusted survival for each cancer. We define the difference in net survival between the oldest (75-99 years) and youngest (15-44 years) patients as the age gap in survival. We evaluated the absolute change (%) in the age gap since 1971. The overall index of net survival increased substantially during the 40-year period 1971-2011, both in England and in Wales. For patients diagnosed in 1971-72, the index of net survival was 50% at 1 year after diagnosis. 40 years later, the same value of 50% was predicted at 10 years after diagnosis. The average 10% survival advantage for women persisted throughout this period. Predicted 10-year net survival adjusted for age and sex for patients diagnosed between 2010 and 2011 ranged from 1·1% for pancreatic cancer to 98·2% for testicular cancer. Net survival for the oldest patients (75-99 years) was persistently lower than for the youngest (15-44 years), even after

    The factors that influence decision making in severe aortic stenosis (AS) are unknown. Our aim was to assess, in patients with severe AS, the determinants of management and prognosis in a multicenter registry that enrolled all consecutive adults with severe AS during a 1-month period. One-year follow-up was obtained in all patients and included vital status and aortic valve intervention (aortic valve replacement [AVR] and transcatheter aortic valve implantation [TAVI]). A total of 726 patients were included, mean age was 77.3 ± 10.6 years, and 377 were women (51.8%). The most common management was conservative therapy in 468 (64.5%) followed by AVR in 199 (27.4%) and TAVI in 59 (8.1%). The strongest association with aortic valve intervention was patient management in a tertiary hospital with cardiac surgery (odds ratio 2.7, 95% confidence interval 1.8 to 4.1, p <0.001). The 2 main reasons to choose conservative management were the absence of significant symptoms (136% to 29.1%) and the presence of co-morbidity (128% to 27.4%). During 1-year follow-up, 132 patients died (18.2%). The main causes of death were heart failure (60% to 45.5%) and noncardiac diseases (46% to 34.9%). One-year survival for patients treated conservatively, with TAVI, and with AVR was 76.3%, 94.9%, and 92.5%, respectively, p <0.001. One-year survival of patients treated conservatively in the absence of significant symptoms was 97.1%. In conclusion, most patients with severe AS are treated conservatively. The outcome in asymptomatic patients managed conservatively was acceptable. Management in tertiary hospitals is associated with valve intervention. One-year survival was similar with both interventional strategies. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate the changes in the mean T2 values of articular cartilage on serial follow-up images up to 1 year in patients who underwent lateral meniscus allograft transplantation (MAT). Fifty-two patients who underwent lateral MAT surgery at our hospital were evaluated preoperatively and at 2 days, 6 weeks, 3 months, 6 months, and 1 year after MAT using 3.0-T magnetic resonance imaging (MRI) that included T2 mapping. T2 value changes according to the arthroscopic grading of chondromalacia were evaluated in the lateral and medial compartment. Lysholm scores were obtained pre- and postoperatively. The T2 values of cartilage were significantly increased 2 days after operation, and then gradually reduced to the baseline level after 1 year in both compartments. In morphologic assessment performed after 1 year, most areas (92.9 %) showed no interval change of chondromalacia grade. Lyshom knee scores increased significantly from the mean preoperative value of 62.5 (range, 23-95) to 89.7 (range, 64-100) at 1 year (p < 0.001). Mean T2 values of cartilage following MAT exhibited a return to baseline level after 1 year. T2 measurement can be a useful tool for quantitative evaluation of postoperative cartilage changes compared to conventional MRI. (orig.)

    To evaluate the influence of the size of proximal cavities on the survival rate of the atraumatic restorative treatment (ART) restorations. A total of 804 children, aged 6-8 years, from a low socio-economic community, with an ART restorable proximal carious lesion in their primary molars, participated. Over a 3-week period, three 'experienced' and four 'inexperienced' operators randomly paired with four 'experienced' and four 'inexperienced' assistants, made the restorations at site using hand instruments. They randomly used Fuji IX, Ketac Molar Easymix and Ketac Molar Aplicap glass ionomer cements to restore the cavities, under randomly selected rubber dam and cotton roll isolation methods. The fillings were independently evaluated by nine trained and calibrated evaluators. After 1 year, the survival rate of the fillings evaluated in the study was 44.8%. Irrespective of the other factors involved, restorations with the highest survival rate were of size between 2 and 3 mm (mesio-distal, bucco-lingual, and depth) or volumes 10.0-19.9 mm(3) (Chi-square, P = 0.002, KM mean survival of 345 days). While the survival rates for class II ART restorations were still low, the choice of medium-sized proximal cavities gave better survival rates for this technique.

    Chronic pelvic pain affects ∼15% of women, and presents a challenging problem for gynecologists due to its complex etiology involving multiple comorbidities. Thus, an interdisciplinary approach has been proposed for chronic pelvic pain, where these multifactorial comorbidities can be addressed by different interventions at a single integrated center. Moreover, while cross-sectional studies can provide some insight into the association between these comorbidities and chronic pelvic pain severity, prospective longitudinal cohorts can identify comorbidities associated with changes in chronic pelvic pain severity over time. We sought to describe trends and factors associated with chronic pelvic pain severity over a 1-year prospective cohort at an interdisciplinary center, with a focus on the role of comorbidities and controlling for baseline pain, demographic factors, and treatment effects. This was a prospective 1-year cohort study at an interdisciplinary tertiary referral center for pelvic pain and endometriosis, which provides minimally invasive surgery, medical management, pain education, physiotherapy, and psychological therapies. Exclusion criteria included menopause or age >50 years. Sample size was 296 (57% response rate at 1 year; 296/525). Primary outcome was chronic pelvic pain severity at 1 year on an 11-point numeric rating scale (0-10), which was categorized for ordinal regression (none-mild 0-3, moderate 4-6, severe 7-10). Secondary outcomes included functional quality of life and health utilization. Baseline comorbidities were endometriosis, irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia, and validated questionnaires for depression, anxiety, and catastrophizing. Multivariable ordinal regression was used to identify baseline comorbidities associated with the primary outcome at 1 year. Chronic pelvic pain severity decreased by a median 2 points from baseline to 1 year (6/10-4/10, P pain subscale of the

    The current state of research on relative age effects in basketball shows an uneven picture. These mixed results might be caused by the interaction of constituent year and within-year effects. Our aim was to examine constituent and within-1-year effects in elite German youth basketball. The sample (n = 4400) included players competing in the JBBL (Under-16 first division) and the NBBL (Under-19 first division) from 2011/2012 until 2013/2014. A multi-way frequency analysis revealed an interaction of constituent year effects and within-1-year effects for the JBBL, χ2 (6, 2590) = 12.76, P < 0.05. NBBL data showed significant constituent year effects, χ2 (2, n = 1810) = 25.32, P < 0.01, and within-1-year effects for all three age bands but no interaction. The interaction between constituent year and within-1-year effects in the JBBL showed reduced within-1-year effects with increasing age. Once players enter the system in the JBBL, relatively younger players seem less likely to drop out of the system. Results offer new insight regarding how the regulations of this talent development system may influence athletes' opportunities to enter the system and their likelihood of staying at the highest levels of competition. © 2016 John Wiley & Sons A/S.

    To describe the 1-year success of a trabecular stent implant in a pseudophakic glaucoma patient. The stent is implanted through a small corneal incision under gonioscopic control. Intraocular pressure control was reported in cultured human anterior segment. Observational case report. We report the case of a patient who was implanted and followed-up for 1 year at the Dipartimento di Fisiopatologia Clinica. The main outcome measures were intraocular pressure and visual field. The patient's intraocular pressure was controlled with topical beta-blockers for 6 months and without therapy for 6 months. Two diurnal curves demonstrated achievement of target pressure during the day. The 1-year visual field was unchanged. We are not aware of previous reports of trabecular stent implantation in pseudophakic patients. The trabecular stent had minimal peri-operative morbidity. Identification of the implantation site is challenging and reduction of efficacy over time may occur.

    Shorter sleep duration is linked to obesity, coronary artery disease, and diabetes. Whether sleep deprivation during the postpartum period affects maternal postpartum weight retention remains unknown. This study examined the association of sleep at 6 months postpartum with substantial postpartum weight retention (SPPWR), defined as 5 kg or more above pregravid weight at 1 year postpartum. The authors selected 940 participants in Project Viva who enrolled during early pregnancy from 1999 to 2002. Logistic regression models estimated odds ratios of SPPWR for sleep categories, controlling for sociodemographic, prenatal, and behavioral attributes. Of the 940 women, 124 (13%) developed SPPWR. Sleep distributions were as follows: 114 (12%) women slept hours/day, 280 (30%) slept 6 hours/day, 321 (34%) slept 7 hours/day, and 225 (24%) slept > or =8 hours/day. Adjusted odds ratios of SPPWR were 3.13 (95% confidence interval (CI): 1.42, 6.94) for hours/day, 0.99 (95% CI: 0.50, 1.97) for 6 hours/day, and 0.94 (95% CI: 0.50, 1.78) for > or =8 hours/day versus 7 hours/day (p = 0.012). The adjusted odds ratio for SPPWR of 2.05 (95% CI: 1.11, 3.78) was twofold greater (p = 0.02) for a decrease in versus no change in sleep at 1 year postpartum. Sleeping hours/day at 6 months postpartum was strongly associated with retaining > or =5 kg at 1 year postpartum. Interventions to prevent postpartum obesity should consider strategies to attain optimal maternal sleep duration.

    The Norton scale is used for assessing the risk of pressure ulcers. The association between low admission Norton scale scores (ANSS), complications and mortality in elderly patients following lower limb amputations has never been studied until now. The aim of this study was to investigate if low ANSSs are associated with complications the 30-day and 1-year mortality in elderly patients following lower limb amputations. The medical charts of 104 elderly (≥ 65 years) patients following lower limb amputations were studied for the following measurements: ANSS, demographics, comorbidities, complications during hospitalization, 30-day mortality and 1-year mortality. Complications included acute coronary syndrome, major bleeding, stroke, systemic infections, organ failure and thromboembolism. An ANSS ≤ 14 was considered as being low. Overall 54 (51.9%) patients underwent below-knee amputations and 50 (48.1%) patients underwent above-knee amputations. Most (n = 78; 75.0 %) patients were men and the mean age was 78.5 ± 7.9 years. Following the amputation 46 (44.2%) patients had complications other than pressure ulcers, 24 (23.1%) patients died within 30 days and 63 (60.6%) patients died within 1 year. A total of 61 (58.7%) patients had a low ANSS. The incidence of complications other than pressure ulcers, 30-day and 1-year mortality rates were higher in patients with a low ANSS relative to patients with a high ANSS. A regression analysis showed that 1-year mortality was independently negatively associated with ANSS (t =  2.629; p = 0.010). The Norton scale can be used for predicting 1-year mortality in elderly patients following lower limb amputations.

    We report clinical outcomes at 1 year or more after high-dose-rate (HDR) electronic brachytherapy (EBT) using surface applicators for the treatment of nonmelanoma skin cancer (NMSC). From July 2009 to April 2012, 122 patients with 171 NMSC lesions were treated with EBT to a dose of 40Gy in eight fractions, delivered twice weekly. At followup, patients were assessed for acute and late toxicities, cosmesis, and local control. Treatment of 171 lesions was completed in 122 patients with a mean age 73 years. There have been no recurrences to date with a mean followup of 10 months (range, 1-28 months). Followup data at 1 year or more were available for 46 lesions in 42 patients. Hypopigmentation (all Grade 1) was present in 5 (10.9%) of 46 lesions at 1 year. Other late effects at 1 year included dry desquamation, alopecia, and rash dermatitis, which occurred in 1 (2.2%), 1 (2.2%), and 3 (6.5%) of 46 lesions, respectively. No Grade 3 or higher adverse events were observed at any time point. Cosmesis was evaluated at 1 year for 42 of 46 lesions and was excellent for 39 (92.9%) and good for 3 (7.1%) of the 42 evaluable lesions. Treatment of NMSC with HDR EBT using surface applicators was effective with no recurrences, good to excellent cosmesis, and acceptable toxicities at 1 year or more after treatment. HDR EBT provides a convenient nonsurgical treatment option for NMSC patients. Copyright © 2013 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

    AIM: Compare the response to oral glucose of the two incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) at 1 year after restrictive vs. malabsorptive bariatric surgery. METHODS: Vertical banded gastroplasty (VBG, n = 7) or jejunoileal bypass...... = 0.007). CONCLUSIONS: We conclude that at 1 year after bariatric surgery, the two incretins show dissociated responses in that the GIP secretion is higher after VBG whereas GLP-1 secretion is higher after JIB. This dissociated incretin response is independent from reduction in body weight, glucose...

    During a period of 1 year, data concerning life events, non-specific psychological symptoms, individual social history, and ulcer history were obtained for consecutive cases of patients about to have elective surgical treatment for duodenal ulcer. At the 1-year follow-up examination a blind, clinical evaluation was performed (dumping, dyspepsia, recurrence, and Visick grading), and information concerning the 94 patients' assessment of outcome was obtained. A multivariate predictor analysis was performed. Most patients (85%) benefited from treatment. The excess rate of non-specific psychological symptoms indicating impairment remained unchanged. The patients assessments of outcome were correlated with the clinical assessment. A positive correlation was found for women to have dumping and poor Visick grade and for unmarried persons to have postoperative dyspepsia and a poor Visick grade. A negative correlation between a long ulcer history and postoperative dyspepsia and a positive correlation between pyloroplasty and dumping were found. Non-specific psychological symptoms predicted poor clinical assessments. It is suggested that it is relevant to apply the patients' assessments for the purpose of evaluation, supplementing the clinical assessment of the more biomedical aspects of outcome.

As more women survive this type of cancer, their quality of life (QOL has become a field of great scientific and social importance. Different types of therapy have varying results on the QOL of patients. In this study, we compared the impact of radiotherapy (RAD and radiochemotherapy (RAD/CHEM on CC patients’QOL. Our sample included 105 women who suffered from CC stages IA-IIIA. They were treated either with RAD or RAD/CHEM, and filled in the questionnaires 1 year after treatment completion. We used 4 questionnaires, EORTC QLQ C-30, EORTC QLQ-C24, Questionnaire of Post-traumatic Psychological Disorder, and Greek Symptom Control Questionnaire by M.D. Anderson, in order to assess their QOL. Except for differences in descriptive characteristics of the patients’ (age, number of children, contraceptives and early toxicity in some organs, no statistically significant difference was observed in the main (physical, sexual, emotional aspects of life between the 2 groups of treated patients. Treatment type had no effect on total QOL. In conclusion, the addition of CHEM to RAD in the treatment plan of CC patients had no significant impact on their QOL

    The molecular profiling of patients with advanced non-small-cell lung cancer (NSCLC) for known oncogenic drivers is recommended during routine care. Nationally, however, the feasibility and effects on outcomes of this policy are unknown. We aimed to assess the characteristics, molecular profiles, and clinical outcomes of patients who were screened during a 1-year period by a nationwide programme funded by the French National Cancer Institute. This study included patients with advanced NSCLC, who were routinely screened for EGFR mutations, ALK rearrangements, as well as HER2 (ERBB2), KRAS, BRAF, and PIK3CA mutations by 28 certified regional genetics centres in France. Patients were assessed consecutively during a 1-year period from April, 2012, to April, 2013. We measured the frequency of molecular alterations in the six routinely screened genes, the turnaround time in obtaining molecular results, and patients' clinical outcomes. This study is registered with ClinicalTrials.gov, number NCT01700582. 18,679 molecular analyses of 17,664 patients with NSCLC were done (of patients with known data, median age was 64·5 years [range 18-98], 65% were men, 81% were smokers or former smokers, and 76% had adenocarcinoma). The median interval between the initiation of analysis and provision of the written report was 11 days (IQR 7-16). A genetic alteration was recorded in about 50% of the analyses; EGFR mutations were reported in 1947 (11%) of 17,706 analyses for which data were available, HER2 mutations in 98 (1%) of 11,723, KRAS mutations in 4894 (29%) of 17,001, BRAF mutations in 262 (2%) of 13,906, and PIK3CA mutations in 252 (2%) of 10,678; ALK rearrangements were reported in 388 (5%) of 8134 analyses. The median duration of follow-up at the time of analysis was 24·9 months (95% CI 24·8-25·0). The presence of a genetic alteration affected first-line treatment for 4176 (51%) of 8147 patients and was associated with a significant improvement in the proportion of patients

  1. Hematuria duration does not predict kidney function at 1 year in ANCA-associated glomerulonephritis

    Objectives Hematuria is considered a marker of active renal disease in ANCA-associated glomerulonephritis (ANCA-GN) with induction immunosuppression often continued until hematuria has resolved. We aim to determine whether longer hematuria duration is associated with lower estimated glomerular filtration rate (eGFR) at 1 year. Methods We conducted a retrospective study of 55 patients with biopsy-proven ANCA-GN. Linear regression models were constructed to determine predictors of eGFR at 1 year. The primary exposure was hematuria (>5 rbc/hpf) duration, defined as hematuria, 95% had proteinuria, and mean serum creatinine was 3.1 [standard deviation (SD) = 2.3] mg/dL. Overall, 93% were treated with steroids in combination with either cyclophosphamide or rituximab. Mean hematuria duration was 92 (SD = 77) days with 34 (62%) patients having hematuria resolution within 90 days. Older age and lower baseline eGFR were associated with lower eGFR at 1 year (p = 0.03 and p Hematuria resolution (hematuria duration does not predict eGFR at 1 year. Our findings provide support that among individuals who are otherwise considered to be in clinical remission, the persistence of hematuria should not delay transition from induction to maintenance immunosuppression.

    There is evidence of cerebral involvement among women with preeclampsia. Levels of the cerebral biomarkers neuron-specific enolase (NSE) and S100B are elevated during pregnancy in women developing preeclampsia. It is although not known if these biomarkers return to normal range postpartum. The aim with this study was to compare levels of S100B and NSE during pregnancy and 1 year postpartum in women who have had preeclampsia to women with normal pregnancies. This study was a longitudinal study of cases (n = 53) with preeclampsia and controls (n = 58) consisted of normal pregnant women in matched gestational weeks. Plasma samples were collected at inclusion during pregnancy and 1 year postpartum. Plasma samples were analyzed for levels of S100B and NSE by enzyme-linked immunosorbent assays kits. Levels of NSE and S100B in women with preeclampsia were higher during pregnancy than in women with normal pregnancies. One year postpartum, women who have had preeclampsia still had a higher median level of both NSE (5.07 vs. 4.28 µg/l, P preeclampsia after adjustment for confounding factors. Levels of NSE correlated to S100B during pregnancy and postpartum. Levels of NSE and S100B are still elevated 1 year postpartum in women who have had preeclampsia in contrast to women with previous normal pregnancies. We hypothesize that there might be a persistent cerebral involvement among women with preeclampsia even 1 year postpartum.

    The purpose of this study is the development of paediatric reference phantoms for newborn and 1-year-old infants to be used for the calculation of organ and tissue equivalent doses in radiation protection. The study proposes a method for developing anatomically highly sophisticated paediatric phantoms without using medical images. The newborn and 1-year-old hermaphrodite phantoms presented here were developed using three-dimensional (3D) modelling software applied to anatomical information taken from atlases, textbooks and images provided by the Department of Anatomy of the Federal University of Pernambuco, Brazil. The method uses polygon mesh surfaces to model body contours, the shape of organs as well as their positions and orientations in the human body. Organ and tissue masses agree with corresponding data given by the International Commission on Radiological Protection for newborn and 1-year-old reference children. Bones were segmented into cortical bone, spongiosa, medullary marrow and cartilage to allow for the use of μCT images of trabecular bone for skeletal dosimetry. Anatomical results show 3D images of the phantoms' surfaces, organs and skeletons, as well as tables with organ and tissue masses or skeletal tissue volumes. Dosimetric results present comparisons of organ and tissue absorbed doses or specific absorbed fractions between the newborn and 1-year-old phantoms and corresponding data for other paediatric stylised or voxel phantoms. Most differences were found to be below 10%.

    2017-08-01

    The Hospital-patient One-year Mortality Risk (HOMR) score is an externally validated index using health administrative data to accurately predict the risk of death within 1 year of admission to the hospital. This study derived and internally validated a HOMR modification using data that are available when the patient is admitted to the hospital. From all adult hospitalizations at our tertiary-care teaching hospital between 2004 and 2015, we randomly selected one per patient. We added to all HOMR variables that could be determined from our hospital's data systems on admission other factors that might prognosticate. Vital statistics registries determined vital status at 1 year from admission. Of 2,06,396 patients, 32,112 (15.6%) died within 1 year of admission to the hospital. The HOMR-now! model included patient (sex, comorbidities, living and cancer clinic status, and 1-year death risk from population-based life tables) and hospitalization factors (admission year, urgency, service and laboratory-based acuity score). The model explained that more than half of the total variability (Regenkirke's R(2) value of 0.53) was very discriminative (C-statistic 0.92), and accurately predicted death risk (calibration slope 0.98). One-year risk of death can be accurately predicted using routinely collected data available when patients are admitted to the hospital. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study examined whether internalizing problems, parental warmth and teacher support were associated with adolescents' experience of future peer victimization in school. Data were drawn from two rounds of the longitudinal Social and Health Assessment (SAHA). Study subjects comprised 593 US urban adolescents (aged 13.8 ± 0.8 years; 56 % female). Results showed that there was a substantial degree of continuity in peer victimization over a 1-year period. The presence of internalizing (anxiety, depressive and somatic) symptoms at baseline was associated with an increased risk of peer victimization over time. Both parental warmth and teacher support were uniquely associated with a lower risk for peer victimization. Implications of these findings for prevention efforts are discussed.

    The mottled duck (Anas fulgivula) is a non-migratory duck dependent on coastal habitats to meet all of its life cycle requirements in the Western Gulf Coast (WGC) of Texas and Louisiana, USA. This population of mottled ducks has experienced a moderate decline during the past 2 decades. Adult survival has been identified as an important factor influencing population demography. Previous work based on band-recovery data has provided only annual estimates of survival. We assessed seasonal patterns of female mottled duck survival from 2009 to 2012 using individuals marked with satellite platform transmitter terminals (PTTs). We used temperature and movement sensors within each PTT to indicate potential mortality events. We estimated cumulative weekly survival and ranked factors influential in patterns of mortality using known-fate modeling in Program MARK. Models included 4 predictors: week; hunting and non-hunting periods; biological periods defined as breeding, brooding, molt, and pairing; and mass at time of capture. Models containing hunt periods, during and outside the mottled duck season, comprised essentially 100% of model weights where both legal and illegal harvest had a negative influence on mottled duck survival. Survival rates were low during 2009–2011 (12–38% annual rate of survival), when compared with the long-term banding average of 53% annual survival. During 2011, survival of female mottled ducks was the lowest annual rate (12%) ever documented and coincided with extreme drought. Management actions maximizing the availability of wetlands and associated upland habitats during hunting seasons and drought conditions may increase adult female mottled duck survival.

    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.

    Background and study aims: Bariatric endoscopy has emerged as an aid in the nonsurgical treatment of obesity. The objective of this study is to critically provide the results and follow-up of endoscopic sleeve gastroplasty 1 year after the procedure. Patients and methods: Prospective single-center follow-up study of 25 patients (5 men, 20 women) who underwent flexible endoscopic suturing for endoluminal gastric volume reduction. A multidisciplinary team provided post-procedure care. Patient outcomes were recorded at 1 year after the procedure. Linear regression analysis was done to evaluate the variables associated with best results at 1 year of follow-up. Results: Mean body mass index (BMI) was 38.5 ± 4.6 kg/m2 (range 30 – 47) and mean age 44.5 ± 8.2 years (range 29 – 60). At 1 year, 22 patients continued with the follow-up (2 dropped out at 6 months and 1 at 3 months). There were no major intra-procedural, early, or delayed adverse events. Mean BMI loss was 7.3 ± 4.2 kg/m2, and mean percentage of total body weight loss was 18.7 ± 10.7 at 1 year. In the linear regression analysis, adjusted by initial BMI, variables associated with %TBWL involved the frequency of nutritional (β = 0.563, P = 0.014) and psychological contacts (β = 0.727, P = 0.025). The number of nutritional and psychological contacts were predictive of good weight loss results. Conclusions: Endoscopic sleeve gastroplasty is a feasible, reproducible, and effective procedure to treat obesity. Nutritional and psychological interaction are predictive of success. PMID:26878054

    Retrospective open cohort. To calculate the survival of patients with spinal cord infarction and to compare the cause of death in patients with different mechanisms of ischaemic injury. Spinal Rehabilitation Unit, Melbourne, Victoria, Australia. Consecutive admissions between 1 January 1995 and 31 December 2008 with recent onset of spinal cord infarction. Linkage to the Registry of Births, Deaths and Marriages (Victoria) was used to determine survival following discharge from in-patient rehabilitation and cause of death. A total of 44 patients were admitted (males=26, 59%), with a median age of 72 years (interquartile range (IQR) 62-79). One patient died during their in-patient rehabilitation programme. In all, 14 patients (n=14/44; 33%) died during the follow-up period. The median survival after diagnosis was 56 months (IQR 28-85) and after discharge from in-patient rehabilitation was 46 months (IQR 25-74). The 1- and 5-year mortality rates were 7.0% (n=3/43; 95% confidence interval (CI)=2.4-18.6%) and 20.9% (n=9/43; 95% CI=11.4-35.2%). There was no statistically significant difference in survival between patients with the different aetiologies of spinal cord infarction (other vs idiopathic: χ(2)=0.6, P=0.7; other vs vascular: χ(2)=1.9, P=0.3). There was no relationship between survival and gender (χ(2)=0.2, P=0.6), age (χ(2)=3.0, P=0.08), level of injury (χ(2)=0.0, P=1) or American Spinal Cord Society Impairment Scale grade of spinal cord injury (χ(2)=0.02, P=0.9). Patients with spinal cord infarction appear to have a fair survival after discharge from in-patient rehabilitation, not withstanding the occurrence of risk factors of vascular disease in many patients.

    Fires have occurred throughout history, including those associated with the meteoroid impact at the Cretaceous–Palaeogene (K–Pg) boundary that eliminated many vertebrate species. To evaluate the recent hypothesis that the survival of the K–Pg fires by ancestral mammals was dependent on their ability to use energy-conserving torpor, we studied body temperature fluctuations and activity of an egg-laying mammal, the echidna (Tachyglossus aculeatus), often considered to be a ‘living fossil’, before, during and after a prescribed burn. All but one study animal survived the fire in the prescribed burn area and echidnas remained inactive during the day(s) following the fire and substantially reduced body temperature during bouts of torpor. For weeks after the fire, all individuals remained in their original territories and compensated for changes in their habitat with a decrease in mean body temperature and activity. Our data suggest that heterothermy enables mammals to outlast the conditions during and after a fire by reducing energy expenditure, permitting periods of extended inactivity. Therefore, torpor facilitates survival in a fire-scorched landscape and consequently may have been of functional significance for mammalian survival at the K–Pg boundary. PMID:27075255

    Full Text Available Background/Aims: Identification of novel biomarkers to identify acute heart failure (AHF patients at high risk of mortality is an area of unmet clinical need. Recently, we reported that the baseline level of circulating miR-30d was associated with left ventricular remodeling in response to cardiac resynchronization therapy in advanced chronic heart failure patients. However, the role of circulating miR-30d as a prognostic marker of survival in patients with AHF has not been explored. Methods: Patients clinically diagnosed with AHF were enrolled and followed up for 1 year. Quantitative reverse transcription polymerase chain reactions were used to determine serum miR-30d levels. The univariate logistic regression analysis and multivariate logistic regression analysis were used to determine the predictors for all-cause mortality in AHF patients. Kaplan–Meier survival analysis was used to analyze the role of miR-30d in prediction of survival. Results: A total of 96 AHF patients were enrolled and followed up for 1 year. Serum miR-30d was significantly lower in AHF patients who expired in the one year follow-up period compared to those who survived. Univariate logistic regression analysis yielded 18 variables that were associated with all-cause mortality in AHF patients, while the multivariate logistic regression analysis identified 4 variables including heart rate, hemoglobin, serum sodium, and serum miR-30d level associated with mortality. ROC curve analysis showed that hemoglobin, heart rate and serum sodium displayed poor prognostic value for AHF (AUCs not higher than 0.700 compared to miR-30d level (AUC = 0.806. Kaplan–Meier survival analysis confirmed that patients with higher serum miR-30d levels had significantly lower mortality (P=0.001. Conclusion: In conclusion, this study shows evidence for the predictive value of circulating miR-30d as 1-year all-cause mortality in AHF patients. Large multicentre studies are further needed to validate

    Kidney transplantation in recipients with a previous malignancy is often deferred 2 to 5 years after cancer treatment due to fear of cancer recurrence. In Norway, the required waiting period has been 1 year. We compared patient and graft survival of recipients with pretransplant cancer to the outcomes of matched recipients without such cancer (comparators) using Cox regression. From 1963 to 2010, 377 (6.4%) of 5867 recipients had a pretransplant cancer. During a median follow-up of 6.8 years, 256 recipients died, 35 (13.7%) from recurrent cancer and 27 (10.5%) from de novo cancer. Uncensored and death-censored graft loss occurred in 263 and 46 recipients, respectively. All-cause mortality was similar as in comparators (hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.93-1.20]; P = 0.40), death-censored graft loss was lower (HR, 0.63; 95% CI, 0.47-0.84; P = 0.002), and uncensored graft loss was similar (HR, 0.99; 95% CI, 0.87-1.12; P = 0.87). Cancer mortality was higher than in comparators (HR, 1.97; 95% CI, 1.51-2.56; P cancer mortality or all-cause mortality (both P > 0.45). Results were similar within cancer subgroups, with most data in patients with a history of kidney cancer, prostate cancer, urothelial cancer, and skin squamous cell carcinoma. Kidney transplant recipients with a pretransplant cancer had a similar overall patient and graft survival as recipients without such cancer. Cancer mortality was increased, particularly during the first 5 years after transplantation. A short waiting period was not associated with mortality.

    Elevated body mass index (BMI) is associated with the incidence, prevalence, and progression of pelvic organ prolapse (POP). This study investigated the effect of peripartum BMI on pelvic floor support 1 year postpartum (PP1y). One hundred eight nulliparous women had their BMI recorded and underwent POP assessments using the Pelvic Organ Prolapse Quantification System at baseline, third trimester (36th to 38th week of pregnancy [G36-38w]), and PP1y. Pelvic organ prolapse was defined as ≥stage II. Women gained on average 1.9 kg between baseline and PP1y. After adjustment, increasing BMI PP1y was associated with increasing anterior wall descent (P pelvic floor laxity 1 year after delivery. Postpartum weight reduction may serve as a strategy for POP prevention in some women. © The Author(s) 2015.

    To evaluate corneal densitometry and higher order aberrations (HOAs) up to 1 year after Bowman layer (BL) transplantation. This was a retrospective study carried out at a tertiary referral center. Fifteen eyes of 14 patients who underwent BL transplantation for advanced keratoconus and had at least 1 year of follow-up were examined before BL transplantation and postoperatively at 1 day, 1 week, and 1, 3, 6, and 12 months. Corrected distance visual acuity (CDVA) with spectacles and contact lenses, anterior and posterior HOAs, and corneal densitometry were analyzed. One year after surgery, average logarithm of the minimum angle of resolution of spectacle-CDVA changed from 1.35 (±0.46) preoperatively to 0.96 (±0.32, P cornea, with a peak 1 month after surgery (P transplantation, whereas corneal backscattering increased, mostly in the central and posterior layers, where the graft has been placed. Changes in HOAs and corneal backscattering did not correlate with CDVA.

    Lowering blood pressure (BP) in stroke survivors reduces the risk of recurrent stroke. We tested the hypothesis that a nurse-led nonpharmacologic intervention would lower the BP of participants in an intervention group compared with a control group. A total of 349 patients who had sustained acute...... stroke or transient ischemic attack were randomly assigned to either usual care or to 4 home visits by a nurse. During the visits, the nurse measured and recorded BP and provided individually tailored counseling on a healthy lifestyle. A total of 303 patients completed the 1-year follow up. No change...... visits by nurses did not result in a lowering of BP. Patients complied with antihypertensive therapy and GP visits in the case of hypertension.

    To prospectively compare the clinical performance of two different resin composites for luting IPS Empress inlays and onlays. 83 IPS Empress restorations were placed in 30 subjects. All restorations were inserted under rubber dam. 43 inlays/onlays were luted with a self-adhesive resin cement [RelyX Unicem (RX)]. A multistep adhesive (Syntac) was used with Variolink II low viscosity (SV) and served as control (n=40). The restorations were evaluated after 2 weeks: Baseline = 1st recall (R1), after 6 months (R2) and after 1 year (R3) by two calibrated examiners using the modified USPHS criteria. From R1 to R3, one failure was noticed in the SV group (R2) due to marginal enamel chipping. After 1 year of clinical service, SV revealed significantly better results regarding color match and integrity inlay (Mann-Whitney U-test, P0.05).

    Full Text Available Purpose: To evaluate renal function 1 year after radical nephrectomy (RN for renal cell carcinoma, the preoperative predictors of postnephrectomy renal function were investigated by sex, and equations to predict the estimated glomerular filtration rate (eGFR 1 year after RN were developed. Materials and Methods: A total of 525 patients who underwent RN between May 2007 and August 2011 at Tohoku University Hospital and its affiliated hospitals were prospectively evaluated. Overall, 422 patients were analyzed in this study. Results: Independent preoperative factors associated with postnephrectomy renal function were different in males and females. Preoperative eGFR, age, tumor size, and body mass index (BMI were independent factors in males, while tumor size and BMI were not independent factors in females. The equations developed to predict eGFR 1 year after RN were: Predicted eGFR in males (mL/min/1.73 m2 =27.99-(0.196×age+(0.497×eGFR+(0.744×tumor size-(0.339×BMI; and predicted eGFR in females=44.57- (0.275×age+(0.298×eGFR. The equations were validated in the validation dataset (R2 =0.63, p<0.0001 and R2 =0.31, p<0.0001, respectively. Conclusions: The developed equations by sex enable better prediction of eGFR 1 year after RN. The equations will be useful for preoperative patient counseling and selection of the type of surgical procedure in elective partial or RN cases.

    To examine the associations between depression in fathers of 1-year-old children and specific positive and negative parenting behaviors discussed by pediatric providers at well-child visits. We performed a cross-sectional secondary analysis by using interview data from 1746 fathers of 1-year-old children in the Fragile Families and Child Wellbeing Study. Positive parenting behaviors included fathers' reports of playing games, singing songs, and reading stories to their children ≥ 3 days in a typical week. Negative parenting behavior included fathers' reports of spanking their 1-year-old children in the previous month. Depression was assessed by using the World Health Organization Composite International Diagnostic Interview Short Form. Weighted bivariate and multivariate analyses of parenting behaviors were performed while controlling for demographics and paternal substance abuse. Overall, 7% of fathers had depression. In bivariate analyses, depressed fathers were more likely than nondepressed fathers to report spanking their 1-year-old children in the previous month (41% compared with 13%; P fathers were less likely to report reading to their children ≥ 3 days in a typical week (adjusted odds ratio: 0.38 [95% confidence interval: 0.15-0.98]) and much more likely to report spanking (adjusted odds ratio: 3.92 [95% confidence interval: 1.23-12.5]). Seventy-seven percent of depressed fathers reported talking to their children's doctor in the previous year. Paternal depression is associated with parenting behaviors relevant to well-child visits. Pediatric providers should consider screening fathers for depression, discussing specific parenting behaviors (eg, reading to children and appropriate discipline), and referring for treatment if appropriate.

    The aim of this paper is twofold: first, to investigate how different ownership structures affect plant survival, and second, to analyze how the presence of foreign multinational enterprises (MNEs) affects domestic plants’ survival. Using a unique and detailed data set on the Swedish manufacturing...... sector, I am able to separate plants into those owned by foreign MNEs, domestic MNEs, exporting non-MNEs, and purely domestic firms. In line with previous findings, the result, when conditioned on other factors affecting survival, shows that foreign MNE plants have lower survival rates than non......-MNE plants. However, separating the non-MNEs into exporters and non-exporters, the result shows that foreign MNE plants have higher survival rates than non-exporting non-MNEs, while the survival rates of foreign MNE plants and exporting non-MNE plants do not seem to differ. Moreover, the simple non...

    Lifestyle factors, such as diet, body weight, and physical activity, are linked to better survival after breast cancer (BC) diagnosis. A high percentage of the Malaysian population is overweight or obese. In addition, studies have shown a disparity in survival among Malaysian women compared with other higher-income countries. The Malaysian Breast Cancer Survivorship Cohort (MyBCC) study aims to study lifestyle factors that affect survival in BC survivors. These are the preliminary findings on the nutritional status of Malaysian BC survivors. Our aim was to evaluate the nutritional status of BC survivors at 1 year after diagnosis. This was a cross-sectional study of 194 participants from the MyBCC study, recruited within 1 year of their diagnosis. Participants completed a 3-day food diary. Malaysian women (aged 18 years and older) who were newly diagnosed with primary BC, managed at the University Malaya Medical Center, and able to converse either in Malay, English, or Mandarin were included. Dietary intake and prevalence of overweight or obesity among participants 1 year after diagnosis were measured. Student's t test and analysis of variance or its equivalent nonparametric test were used for association in continuous variables. About 66% (n=129) of participants were overweight or obese and >45% (n=86) had high body fat percentage 1 year after diagnosis. The participants' diets were low in fiber (median=8.7 g/day; interquartile range=7.2 g/day) and calcium (median=458 mg/day; interquartile range=252 mg/day). Ethnicity and educational attainment contributed to the differences in dietary intake among participants. Higher saturated fat and lower fiber intake were observed among Malay participants compared with other ethnic groups. Overweight and obesity were highly prevalent among BC survivors and suboptimal dietary intake was observed. Provision of an individualized medical nutrition therapy by a qualified dietitian is crucial as part of comprehensive BC survivorship

  16. Survival during the Breeding Season: Nest Stage, Parental Sex, and Season Advancement Affect Reed Warbler Survival.

    Kaja Wierucka

    Full Text Available Avian annual survival has received much attention, yet little is known about seasonal patterns in survival, especially of migratory passerines. In order to evaluate survival rates and timing of mortality within the breeding season of adult reed warblers (Acrocephalus scirpaceus, mark-recapture data were collected in southwest Poland, between 2006 and 2012. A total of 612 individuals (304 females and 308 males were monitored throughout the entire breeding season, and their capture-recapture histories were used to model survival rates. Males showed higher survival during the breeding season (0.985, 95% CI: 0.941-0.996 than females (0.869, 95% CI: 0.727-0.937. Survival rates of females declined with the progression of the breeding season (from May to August, while males showed constant survival during this period. We also found a clear pattern within the female (but not male nesting cycle: survival was significantly lower during the laying, incubation, and nestling periods (0.934, 95% CI: 0.898-0.958, when birds spent much time on the nest, compared to the nest building and fledgling periods (1.000, 95% CI: 1.00-1.000, when we did not record any female mortality. These data (coupled with some direct evidence, like bird corpses or blood remains found next to/on the nest may suggest that the main cause of adult mortality was on-nest predation. The calculated survival rates for both sexes during the breeding season were high compared to annual rates reported for this species, suggesting that a majority of mortality occurs at other times of the year, during migration or wintering. These results have implications for understanding survival variation within the reproductive period as well as general trends of avian mortality.

    Multicenter, randomized, controlled trial on preoperative pain neuroscience education (NE) for lumbar radiculopathy. To determine if the addition of NE to usual preoperative education would result in superior outcomes with regard to pain, function, surgical experience, and health care utilization postsurgery. One in 4 patients after lumbar surgery (LS) for radiculopathy experience persistent pain and disability, which is nonresponsive to perioperative treatments. NE focusing on the neurophysiology of pain has been shown to decrease pain and disability in populations with chronic low back pain. Eligible patients scheduled for LS for radiculopathy were randomized to receive either preoperative usual care (UC) or a combination of UC plus 1 session of NE delivered by a physical therapist (verbal one-on-one format) and a NE booklet. Sixty-seven patients completed the following outcomes prior to LS (baseline), and 1, 3, 6, and 12 months after LS: low back pain (numeric rating scale), leg pain (numeric rating scale), function (Oswestry Disability Index), various beliefs and experiences related to LS (10-item survey with Likert scale responses), and postoperative utilization of health care (utilization of health care questionnaire). At 1-year follow-up, there were no statistical differences between the experimental and control groups with regard to primary outcome measure of low back pain (P = 0.183), leg pain (P = 0.075), and function (P = 0.365). In a majority of the categories regarding surgical experience, the NE group scored significantly better: better prepared for LS (P = 0.001); preoperative session preparing them for LS (P < 0.001) and LS meeting their expectations (P = 0.021). Health care utilization post-LS also favored the NE group (P = 0.007) resulting in 45% less health care expenditure compared with the control group in the 1-year follow-up period. NE resulted in significant behavior change. Despite a similar pain and functional trajectory during the 1-year

    To clinically evaluate the horizontal stability of a connective tissue graft (CTG) at the buccal aspect of single implants (1); to compare actual gingival thickness between thin and thick gingival biotype (2). Periodontally healthy non-smoking patients with a single implant in the anterior maxilla (15-25) were selected for a prospective case series. All demonstrated a horizontal alveolar defect and were in need of contour augmentation by means of CTG for aesthetic reasons. Patients were enrolled 3 months after implant surgery and had been provided with a provisional screw-retained crown. CTG was inserted in the buccal mucosa via the envelope technique using one intrasulcular incision. An ultrasonic device was used to evaluate mucosal thickness (MT) at the buccal aspect. MT was assessed at t0 (before CTG), t1 (immediately after CTG), t2 (2 weeks after CTG = suture removal), t3 (3 months after CTG = permanent crown installation) and t4 (1 year after implant placement). The gingival biotype was categorized as thin or thick based on the transparency of a periodontal probe through the soft tissues while probing the buccal sulcus of the contra-lateral tooth. Gingival thickness (GT) was measured at the contra-lateral tooth using the same ultrasonic device. Thirty-seven patients (19 men, 18 women; mean age 38) met the selection criteria and consented to the treatment. Mean soft tissue gain immediately after CTG was on average 1.07 mm (SD 0.49). What remained of this tissue gain after 1 year was on average 0.97 mm (SD 0.48; 90.5%). Hence, mean soft tissue loss amounted to 0.10 mm (SD 0.23; 9.5%; p = 0.015) with no significant difference between patients with a thin or thick biotype (p ≥ 0.290). Patients with a thin biotype had a mean GT of 1.02 mm (SD 0.21), whereas GT was on average 1.32 mm (SD 0.31) in subjects with a thick biotype (p = 0.004). Connective tissue graft substantially thickens the peri-implant mucosa with acceptable stability over a 1-year period. © 2015

  1. Survival strategies in arctic ungulates

    Directory of Open Access Journals (Sweden)

    N. J. C. Tyler

    1990-09-01

    Full Text Available Arctic ungulates usually neither freeze nor starve to death despite the rigours of winter. Physiological adaptations enable them to survive and reproduce despite long periods of intense cold and potential undernutrition. Heat conservation is achieved by excellent insulation combined with nasal heat exchange. Seasonal variation in fasting metabolic rate has been reported in several temperate and sub-arctic species of ungulates and seems to occur in muskoxen. Surprisingly, there is no evidence for this in reindeer. Both reindeer and caribou normally maintain low levels of locomotor activity in winter. Light foot loads are important for reducing energy expenditure while walking over snow. The significance and control of selective cooling of the brain during hard exercise (e.g. escape from predators is discussed. Like other cervids, reindeer and caribou display a pronounced seasonal cycle of appetite and growth which seems to have an intrinsic basis. This has two consequences. First, the animals evidently survive perfectly well despite enduring negative energy balance for long periods. Second, loss of weight in winter is not necessarily evidence of undernutrition. The main role of fat reserves, especially in males, may be to enhance reproductive success. The principal role of fat reserves in winter appears to be to provide a supplement to, rather than a substitute for, poor quality winter forage. Fat also provides an insurance against death during periods of acute starvation.

    The aim of this study was to determine risk factors for survival after retrograde placement of ureteral stents and develop a prognostic model for advanced gastrointestinal tract (GIT: esophagus, stomach, colon and rectum) cancer patients. We examined the clinical records of 122 patients who underwent retrograde placement of a ureteral stent against malignant extrinsic ureteral obstruction. A prediction model for survival after stenting was developed. We compared its clinical usefulness with our previous model based on the results from nephrostomy cases by decision curve analysis. Median follow-up period was 201 days (8-1490) and 97 deaths occurred. The 1-year survival rate in this cohort was 29%. Based on multivariate analysis, primary site of colon origin, absence of retroperitoneal lymph node metastasis and serum albumin >3g/dL were significantly associated with a prolonged survival time. To develop a prognostic model, we divided the patients into 3 risk groups of favorable: 0-1 factors (N.=53), intermediate: 2 risk factors (N.=54), and poor: 3 risk factors (N.=15). There were significant differences in the survival profiles of these 3 risk groups (P<0.0001). Decision curve analyses revealed that the current model has a superior net benefit than our previous model for most of the examined probabilities. We have developed a novel prognostic model for GIT cancer patients who were treated with retrograde placement of a ureteral stent. The current model should help urologists and medical oncologists to predict survival in cases of malignant extrinsic ureteral obstruction.

    -word propensity score analysis, ticagrelor did not affect the risk of MACE during the hospital phase, or the incidence of hospital bleeding in patients with STEMI. However, in this mono-centric experience, ticagrelor resulted in improved 1-year survival, even after correction by propensity score.

    Background Following gastric bypass surgery (GBP), there is a post-prandial rise of incretin and satiety gut peptides. The mechanisms of enhanced incretin release in response to nutrients after GBP is not elucidated and may be in relation to altered nutrient transit time and/or malabsorption. Methods Seven morbidly obese subjects (BMI=44.5±2.8 kg/m2) were studied before and 1 year after GBP with a d-xylose test. After ingestion of 25 g of d-xylose in 200 mL of non-carbonated water, blood samples were collected at frequent time intervals to determine gastric emptying (time to appearance of d-xylose) and carbohydrate absorption using standard criteria. Results One year after GBP, subjects lost 45.0±9.7 kg and had a BMI of 27.1±4.7 kg/m2. Gastric emptying was more rapid after GBP. The mean time to appearance of d-xylose in serum decreased from 18.6±6.9 min prior to GBP to 7.9±2.7 min after GBP (p=0.006). There was no significant difference in absorption before (serum d-xylose concentrations=35.6±12.6 mg/dL at 60 min and 33.9±9.1 mg/dL at 180 min) or 1 year after GBP (serum d-xylose=31.5± 18.1 mg/dL at 60 min and 27.2±11.9 mg/dL at 180 min). Conclusions These data confirm the acceleration of gastric emptying for liquid and the absence of carbohydrate malabsorption 1 year after GBP. Rapid gastric emptying may play a role in incretin response after GBP and the resulting improved glucose homeostasis. PMID:22527599

    Although women with gestational diabetes mellitus (GDM) are advised to incorporate physical activity into their lifestyle in order to reduce their risk of developing type 2 diabetes (T2DM), it is recognized that new mothers face barriers to postpartum exercise. Thus, we sought to determine whether, following the diagnosis of GDM, women indeed alter their postpartum physical activity patterns, as compared to their peers without GDM. In this prospective observational cohort study, we assessed the physical activity patterns of 238 white women (58 with GDM, 180 without GDM) in the year before pregnancy and in the year following delivery, using the Baecke questionnaire, which evaluates the following three domains of physical activity: work, sport activity, and nonsport leisure-time activity. Before diagnosis with GDM, women reported lower pregravid sport (P = 0.010) and leisure-time activity (P = 0.013), compared to their peers without GDM. By 1 year postpartum, however, there were no longer significant differences between the GDM and non-GDM groups in either sport or leisure-time activity (P = 0.078 and P = 0.957, respectively). In particular, women with GDM significantly increased their leisure-time activity over the first year postpartum (F = 10.1, P = 0.002), whereas the non-GDM group did not (F = 0.00, P = 0.984). Indeed, on multiple linear regression analysis, GDM independently predicted an increase in leisure-time activity between 1 year pregravid and 1 year postpartum (t = 2.55, P = 0.012). Furthermore, this significant relationship persisted even after adjustment for the finding of prediabetes/diabetes at 3 months postpartum (t = 2.83, P = 0.005). In conclusion, women with GDM successfully increased their leisure-time activity in the first year postpartum, reflecting an element of lifestyle change following this diagnosis.

    Arterial stiffness, measured with pulse wave velocity (PWV), is now classified as a marker of target organ damage (TOD) alongside left ventricular hypertrophy and moderately increased albuminuria. Interventional studies on treated hypertensive patients have shown that PWV could be improved. Our aim was to assess changes in arterial stiffness after 1 year of routine clinical practice in never-treated hypertensive patients. We studied 356 never-treated patients with suspected hypertension. After standard clinical assessment during which presence of TOD was evaluated, hypertension diagnosis was confirmed in 231 subjects who subsequently received standard routine care. Both hypertensive and the 125 controls came back for a follow-up visit after 1 year. Hypertensive patients were slightly older (46 ± 12 vs. 50 ± 12 years, P < 0.001), with higher mean arterial pressure (MAP)-adjusted PWV compared to controls (8.6 ± 2.0 vs. 8.0 ± 1.7 m/s, P < 0.001) and 47% of them presented 1 or more TOD. After 1 year of treatment, MAP was similar in both groups (94.9 vs. 96.2 mm Hg; P = ns), but adjusted PWV remained significantly higher in the hypertensive patients (7.8 ± 1.4 vs. 8.3 ± 1.7 m/s, P = 0.004). The prevalence of elevated PWV was reduced from 20% to 12%. All antihypertensive drugs achieved the same blood pressure (BP) and PWV reduction with the exception of vasodilating beta-blockers which gave slightly better results probably due to heart rate reduction. BP reduction in newly diagnosed hypertensive patients improves arterial stiffness within a year of real-life clinical practice. Patients with the highest PWV and the largest reduction of BP "destiffened" the most whatever antihypertensive class was used.

    The purpose of the present study was to evaluate the problems, treatment outcome, and contributory factors to delayed presentation in Hirschsprung's disease (HD) after 1 year of age in a resource-limited setting. This retrospective study included 41 children aged >1 year with HD managed at the University of Nigeria Teaching Hospital, Enugu, in south eastern Nigeria, between January 2000 and June 2009. Complications of HD were evident at presentation in 38 (92.7%) of the 41 children. Late presentation was due to delayed referral in 27 cases (65.9%), parental ignorance in 11 (26.8%), and poverty in 3 (7.3%). The HD was rectosigmoid in 33 patients (80.5%) and was of ultra-short length variety in 8 patients (19.5%). Thirty-five patients (85.4%) required colostomy for decompression, and colostomy-related complications occurred in 24 of them (68.6%). The definitive surgical procedure was a Swenson pullthrough in 34 cases (82.9%) and posterior myectomy in 7 others (17.1%). Twenty patients (48.8%) experienced at least one postoperative complication. After follow-up of 7-64 months (mean: 31 months), 31 (75.6%) patients had a good outcome, 6 (14.6%) had persistent constipation, 3 had (7.3%) incontinence, and one child (2.4%) died from overwhelming infection. Hirschsprung's disease presenting after 1 year of age may be associated with high colostomy rates and increased morbidity. Continued dissemination of updated information on HD to medical practitioners and a public awareness campaign may improve time to diagnosis.

    Various surgical meshes are used in the repair of inguinal hernia and are associated with numerous complications. Our main objective in this study was to determine whether a biologic hernia matrix is equivalent to polypropylene mesh in an open inguinal hernia repair using the Lichtenstein technique. A prospective, randomized, double-blinded, single-center trial was conducted to evaluate the efficacy of a biologic Inguinal Hernia Matrix (IHM; Cook Medical) compared with polypropylene (PP) mesh using Lichtenstein's inguinal hernia repair in a 3-year outcomes study. Patients were evaluated for recurrence and complications by a blinded surgeon at 2 weeks, 3 months, 6 months, and 1 year post procedure. Patient demographics, including comorbidities and nutrition status, were recorded. Intraoperative information including hernia type and location, procedure time, level of difficulty, degree of surgeon frustration, and surgical experience were collected. One hundred male patients provided informed consent and were randomized into the study in a 1:1 fashion. There were no significant differences in degree of difficulty and level of frustration between the 2 groups. At 1-year follow-up, 3 recurrences were diagnosed in the IHM group as compared with none in the PP group (p = 0.11). Persistent pain trended higher in the PP group (6% vs 4%). All 3 recurrences occurred in the direct inguinal hernia group and were performed by attendings in the first year post training (3 different attendings). No recurrences occurred in patients operated on by more senior surgeons. The IHM hernioplasty compares favorably with PP mesh at 1-year follow-up with similar recurrence rates and complications. Surgeon experience appears to be a major factor affecting successful outcomes. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    High blood pressure at rest has been an established risk factor for cardiovascular disease. However the relationship between Systolic Blood Pressure (SBP) and 1-year-mortality among acute chest pain patients presenting to Emergency Department (ED); and effects of preexisting renal insufficiency, hemodynamic stress - as quantified by Brain Natriuretic Peptide (BNP) and chest pain duration, on this relationship is unknown. Data was used from APACE (Advantageous Predictors of Acute Coronary Syndrome Evaluation), a prospective observational multicenter study of 1240 ED chest pain patients. SBP at presentation was categorized into quartiles: Q1≤127mmHg; Q2 128-142mmHg; Q3 143-160mmHg; Q4≥161mmHg. 60 deaths occurred during 1-year. One-year-mortality-rate showed lower Hazard Ratios for Q2, Q3 and Q4 vs Q1 (HR [95% CI]; 0.39 (0.19-0.78), 0.34 (0.17-0.70), 0.35 (0.17-0.72); pPatients showed progressively better prognosis from Q2 through Q4 vs Q1 only in patients who presented to ED with for more than 12h of chest pain duration. Patients with renal insufficiency had lower SBP at presentation than others (p=0.001). There was no association between the outcome and interaction variable of SBP quartiles and BNP (p=0.27). Acute chest pain patients presenting to ED exhibit an inverse association between SBP at presentation and 1-year-mortality; a relationship which appears stronger in those who present with chest pain of greater than 12h duration.

    The CASES-PMS (Carotid Artery Stenting With Emboli Protection Surveillance-Post-Marketing Study) multicenter, prospective, single-arm, surveillance study was designed to assess the safety and efficacy of carotid artery stenting (CAS) when performed by physicians with varied experience in CAS utilizing a formal training program. Whether the excellent results achieved at 30 days would be sustained to 1 year was the subject of the current investigation. Previously, the pivotal SAPPHIRE (Stenting and Angioplasty with Protection of Patients with High Risk for Endarterectomy) trial demonstrated that CAS was not inferior to carotid endarterectomy (CEA) when performed by physicians experienced in carotid stenting. High surgical-risk patients with de novo atherosclerotic or post-endarterectomy restenotic lesions in native carotid arteries were enrolled at participating centers. Inclusion and exclusion criteria matched those of the SAPPHIRE trial. The primary end point was a composite of 30-day major adverse events (MAE) including death, any stroke, or myocardial infarction. A total of 1,492 patients were enrolled at 73 sites. The primary end point of 30-day MAE was 5.0%, meeting criteria for noninferiority to the prespecified objective performance criteria (OPC) established by the SAPPHIRE trial. The 1-year cumulative percentage of MAE was 12.5% by Kaplan-Meier analysis. All strokes to 30 days plus ipsilateral stroke between 31 and 360 days with CASES-PMS (5.4%) was similar to the rate seen with the SAPPHIRE trial stent cohort (4.9%). There were no significant differences in outcomes at 1 year by symptom status and high-risk status. With the formalized training program utilized in this study, physicians with varied experience in carotid stenting can achieve similar short- and longer-term results to the highly experienced SAPPHIRE Investigators.

    Abstract Deficiency in 25-hydroxyvitamin D (25[OH]D), the main circulating form of vitamin D in blood, could be involved in the pathogenesis of acute coronary syndromes (ACS). To date, however, the possible prognostic relevance of 25 (OH)D deficiency in ACS patients remains poorly defined. The purpose of this prospective study was to assess the association between 25 (OH)D levels, at hospital admission, with in-hospital and 1-year morbidity and mortality in an unselected cohort of ACS patients. We measured 25 (OH)D in 814 ACS patients at hospital presentation. Vitamin D serum levels >30 ng/mL were considered as normal; levels between 29 and 21 ng/mL were classified as insufficiency, and levels < 20 ng/mL as deficiency. In-hospital and 1-year outcomes were evaluated according to 25 (OH)D level quartiles, using the lowest quartile as a reference. Ninety-three (11%) patients had normal 25 (OH)D levels, whereas 155 (19%) and 566 (70%) had vitamin D insufficiency and deficiency, respectively. The median 25 (OH)D level was similar in ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) patients (14.1 [IQR 9.0–21.9] ng/mL and 14.05 [IQR 9.1–22.05] ng/mL, respectively; P = .88). The lowest quartile of 25 (OH)D was associated with a higher risk for several in-hospital complications, including mortality. At a median follow-up of 366 (IQR 364–379) days, the lowest quartile of 25 (OH)D, after adjustment for the main confounding factors, remained significantly associated to 1-year mortality (P < .01). Similar results were obtained when STEMI and NSTEMI patients were considered separately. In ACS patients, severe vitamin D deficiency is independently associated with poor in-hospital and 1-year outcomes. Whether low vitamin D levels represent a risk marker or a risk factor in ACS remains to be elucidated. PMID:25984675

    The preschool years provide a unique window of opportunity to intervene on obesity-related lifestyle risk factors during the formative years of a child's life. The purpose of this study was to assess the impact of a preschool-based obesity prevention effectiveness trial at 1-year follow-up. RCT. Primarily African American children (aged 3-5 years, N=618) attending Head Start preschool programs administered by Chicago Public Schools. Eighteen preschools were randomly assigned in 2007-2008 to receive either (1) a 14-week teacher-delivered intervention focused on healthy lifestyle behaviors or (2) a 14-week teacher-delivered general health curriculum (control group). The primary outcome, BMI, was measured at baseline, postintervention, and 1-year follow-up. Diet and screen time behaviors were also assessed at these time points. Multilevel mixed effects models were used to test for between-group differences. Data were analyzed in 2014. Significant between-group differences were observed in diet, but not in BMI z-score or screen time at 1-year follow-up. Diet differences favored the intervention arm over controls in overall diet quality (p=0.02) and in subcomponents of diet quality, as measured by the Healthy Eating Index-2005, and in fruit intake (servings/day, excludes juice) (p=0.02). Diet quality worsened more among controls than the intervention group at 1-year follow-up. The adaptation of Hip-Hop to Health Jr. produced modest benefits in diet quality but did not significantly impact weight gain trajectory. Not unlike other effectiveness trials, this real-world version delivered by Head Start teachers produced fewer benefits than the more rigorous efficacy trial. It is important to understand and build upon the lessons learned from these types of trials so that we can design, implement, and disseminate successful evidence-based programs more widely and effectively.

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

    Previous studies about the effectiveness of Dialectical Behaviour Therapy for the treatment of Borderline Personality Disorder have had promising results. However, no previous studies have examined its effectiveness when delivered in low secure inpatient services for women. To evaluate clinical outcomes during and after a 1-year period of admission within a low secure unit for women offering a Dialectical Behaviour Therapy programme. A naturalistic, within subjects study of clinical data collected as part of routine practice was conducted. Participants were 18 consecutively admitted women who met the diagnostic criteria for Borderline Personality Disorder and had completed at least 1 year of treatment. Measures covered: risk behaviours; self-reported symptoms of Borderline Personality Disorder, and current mood and symptom experience; staff reports of clinical problems, needs and social functioning. Scores were compared between admission and at 6 months and 1 year. There was a statistically significant improvement on all 13 measures over the year's treatment. Most improvement was demonstrated between admission and 6 months. Engagement in1-year's treatment was associated with significant reduction in risk behaviours and both staff-rated and self-rated outcome measures. Some significant questions remain about which elements of the programme are most effective but the results are encouraging.

    To investigate the association between short sleep duration and elevated body mass index (BMI) and obesity in a large sample of Japanese adults over a short period. Prospective design with baseline in 2006 and 1-year follow-up. Workplaces of an electric power company in Japan. 35,247 company employees (31,477 men, 3,770 women) distributed throughout Japan. Measured weight and height and self-reported sleep duration were obtained at annual health checkup in 2006 and 2007. Weight change was defined as the difference in body mass index (BMI) between the baseline and 1 year later. Relative to the reference category (sleep duration 7-8 h), short sleep duration (long sleep duration > or = 9 h were associated with an increased risk of weight gain among men after adjustment for covariates. Of the non-obese (BMI or = 25) 1 year later. Higher incidence of obesity was observed among the groups with shorter sleep duration. Adjusted odds ratios for the development of obesity were 1.91 (95% CI 1.36, 2.67) and 1.50 (95% CI 1.24, 1.80) in men who slept sleep duration and weight gain or obesity was found for women. Short sleep duration was associated with weight gain and the development of obesity over 1 year in men, but not in women.

    Exercise training can reduce hepatic fat accumulation and cardiovascular risk among patients with non-alcoholic fatty liver disease (NAFLD), but how long these benefits extend beyond the period of active intervention is unclear. Intrahepatic triglyceride (IHTG) content, measured by proton magnetic resonance spectroscopy, and metabolic risk factors among 220 obese people with NAFLD, who were randomly assigned to vigorous/moderate exercise, moderate exercise or no exercise (control), were assessed at 1 year after the 12-month exercise intervention. IHTG content was significantly reduced in the 2 exercise groups compared with the control group over the 12-month active intervention. It was significantly lower (by -2.39%) in the vigorous/moderate exercise group compared with the control group at the 1-year follow-up (95% confidence interval -4.72 to -0.05%; P = .045). Waist circumference and blood pressure remained significantly lower in the vigorous/moderate exercise group and the moderate exercise group compared with the control group at the 1-year follow-up. Visceral adipose fat remained significantly reduced, but with no differences among 3 groups. These findings suggest 12-month exercise intervention induced reductions in hepatic fat accumulation, abdominal obesity and blood pressure for up to 1 year after the active intervention, with some attenuation of the benefits. © 2016 John Wiley & Sons Ltd.

    To analyse long-term functional recovery, deficits and requirement of lower limb orthosis (LLO) for locomotion in patients with Guillain-Barre Syndrome (GBS). Prospective longitudinal follow-up study. Neurological Rehabilitation unit of university hospital. Sixty-nine patients of GBS admitted for inpatient rehabilitation. Thirty-five patients (M:F, 19:16) reporting after 1 year follow-up (50.72%) were included in study (between September 2005 and July 2009). Their residual deficits and requirement of LLO were recorded and analysed. Age ranged from 4 to 65 year (29.74 ± 15.75). Twenty-seven patients had typical GBS and eight patients had acute motor axonal neuropathy variant. Twenty-eight patients (80%) had neuropathic pain needing medication with 11 required more than one drug. Twenty-one patients (60%) had foot drop and advised ankle-foot orthosis-AFO (20 bilateral AFO). Thirty patients (85.71%) needed assistive devices also for locomotion at discharge. After 1 year, foot drop was still present in 12 patients (34.28%) using orthosis. Modified Barthel Index scores, Modified Rankin Scale and Hughes Disability Scale were used to assess functional disabilities. Significant recovery was observed at the time of discharge and after 1 year (p < 0.001 each). Patients with GBS continue to show significant functional recovery for long period. They have residual deficits even after 1 year with requirement of orthosis in large number of patients.

    To assess prospectively the prognostic value of FDG PET/CT during curative-intent radiotherapy (RT) with or without concomitant chemotherapy in patients with non-small-cell lung cancer (NSCLC). Patients with histological proof of invasive localized NSCLC and evaluable tumour, and who were candidates for curative-intent radiochemotherapy (RCT) or RT were preincluded after providing written informed consent. Definitive inclusion was conditional upon significant FDG uptake before RT (PET{sub 1}). All included patients had a FDG PET/CT scan during RT (PET{sub 2}, mean dose 43 Gy) and were evaluated by FDG PET/CT at 3 months and 1 year after RT. The main endpoint was death (from whatever cause) or tumour progression at 1 year. Of 77 patients preincluded, 52 were evaluable. Among the evaluable patients, 77 % received RT with induction chemotherapy and 73 % RT with concomitant chemotherapy. At 1 year, 40 patients (77 %) had died or had tumour progression. No statistically significant association was found between stage (IIIB vs. other), histology (squamous cell carcinoma vs. other), induction or concomitant chemotherapy, and death/tumour progression at 1 year. The SUV{sub max} in the PET{sub 2} scan was the single variable predictive of death or tumour progression at 1 year (odds ratio 1.97, 95 % CI 1.25 - 3.09, p = 0.003) in multivariate analysis. The area under the receiver operating characteristic curve was 0.85 (95 % CI 0.73 - 0.94, p < 10{sup -4}). A SUV{sub max} value of 5.3 in the PET{sub 2} scan yielded a sensitivity of 70 % and a specificity of 92 % for predicting tumour progression or death at 1 year. This prospective multicentre study demonstrated the prognostic value in terms of disease-free survival of SUV{sub max} assessed during the 5th week of curative-intent RT or RCT in NSCLC patients (NCT01261598; RTEP2 study).

    Knee injuries may lead to pain and to functional limitations in the activities of daily living. Patients with knee injuries are frequently seen in general practice; however, the outcome and management in these patients is not known. To assess the outcome and management of knee injuries at 12 months' follow-up in general practice. A prospective observational cohort study with a 1-year follow-up. Primary health care. Adult patients consulting their GP after knee injury (n = 134) participated in the cohort. A magnetic resonance imaging scan was carried out and patients were diagnosed as either no lesion or an isolated meniscal tear, an isolated collateral or cruciate ligament lesion, or a combination. Follow-up questionnaires were filled in up to 12 months' follow-up. At 12 months' follow-up, 34 patients reported full recovery and 67 patients reported major improvement. At baseline, 37 patients (28%) were referred to physical therapy and 17 patients (13%) were referred to secondary care. During 1 year of follow-up, another 21 referrals to physical therapy and 11 referrals to secondary care took place. The pain severity decreased the most, and the Lysholm knee score increased in the majority of patients during the first 3 months after injury. In total, 18 arthroscopies were performed in 15 patients. One patient underwent an anterior cruciate ligament reconstruction. The vast majority of patients report clinically relevant recovery. There is no clear difference in outcomes between patients with meniscal tears or ligament lesions and patients without these diagnoses.

    Depression is a frequent sequela of stroke that negatively interferes with rehabilitation outcome. Personality traits have been neglected as potential vulnerability factors for poststroke depression (PSD). In a 1-year prospective study, the influence of the 5 main personality traits (ie, neuroticism, extraversion, openness, agreeableness, and conscientiousness) on the development of PSD was studied. One month after stroke, 190 consecutive patients with a first-ever supratentorial infarct were asked to complete a personality inventory, the NEO-Five Factor Inventory, which is based on the Five Factor Model of personality. Depressive symptoms were assessed 1, 3, 6, 9, and 12 months after stroke with 3 self-rating questionnaires as screening instruments for depression. PSD was diagnosed as major or minor depression through the use of the Structured Clinical Interview from the Diagnostic and Statistical Manual of Mental Disorders. The 1-year cumulative incidence of depression was 38.7%. Cox regression analysis showed that patients with high neuroticism scores had a 4.6-times-higher risk of developing PSD than patients with low neuroticism scores (P=0.001) regardless of lesion location. Level of handicap was the only other factor that showed an independent effect on the occurrence of PSD. Neuroticism is an important predictor of PSD, a finding that emphasizes the need to take personality into account as a potential vulnerability factor for depression in stroke patients. Research on PSD should aim at delineating the interplay between neurological and psychological factors in the development of PSD.

    Unlike conventional loading protocols, the immediate loading of single implants has not been fully investigated. The purpose of this study was to assess the prosthetic and esthetic periimplant mucosal outcomes of immediately restored dental implants during a 1-year follow-up. Twenty participants meeting the established inclusion criteria received double-threaded, tapered body dental implants (SuperLine; Dentium). Implants were placed and stabilized at a minimum of 35 Ncm of torque and restored immediately after the surgery with interim restorations. These were replaced with definitive restorations 6 months after implant placement. Clinical measurements at each visit included resonance frequency analysis, the evaluation of the participants' oral health (gingival and plaque indices), and the esthetic outcome of the interim or definitive restoration. Implants placed in this clinical study had a 100% success rate. The oral health and esthetic outcomes were favorable for all participants. Double-threaded, tapered body dental implants that were placed and immediately restored with fixed interim prostheses and with definitive prostheses after 6 months remained stable and functional after 1 year.

    To explore the effects of anti-tumour necrosis factor (TNF)alpha antibody therapy on bone mineral density (BMD) of the lumbar spine and femur neck in patients with rheumatoid arthritis (RA). A total of 50 patients with active RA (DAS28> or =3.2) who started adalimumab (40 mg subcutaneously/2 weeks) were included in an open label prospective study. All patients used stable methotrexate and were allowed to use prednisone (< or =10 mg/day). The BMD of the lumbar spine and femur neck was measured before and 1 year after start of treatment. Disease activity at baseline (28-joint Disease Activity Score (DAS28)) and disease duration were inversely correlated with femoral neck BMD and lumbar spine BMD (p<0.05). Mean BMD of lumbar spine and femur neck remained unchanged after 1 year of adalimumab therapy (+0.3% and +0.3%, respectively). Of interest, a beneficial effect of prednisone on change in femur neck BMD was observed with a relative increase with prednisone use (+2.5%) compared to no concomitant prednisone use (-0.7%), (p = 0.015). In contrast to the progressive bone loss observed after conventional disease-modifying antirheumatic drug therapy, TNF blockade may result in an arrest of general bone loss. Consistent with previous observations, the data also suggest that the net effect of low-dose corticosteroids on BMD in RA may be beneficial, possibly resulting from their anti-inflammatory effects.

    The coexistence of depression with mild cognitive impairment (MCI) seems to increase the risk of dementia. However, the explanations of that relationship have been inconsistent. We investigated cognitive profiles in patients with MCI with and without depression and whether changes in depression symptoms affect cognition longitudinally. For the study, 161 patients with MCI were divided into a depressed group (D+) and a nondepressed group (D-). After 1 year, we redivided the original D- group into D- and newly developed depression (Dd) groups and the D+ group into improved depression (Di) and nonimproved depression (Dn) groups. Neuropsychological tests assessing depression and cognitive domains were performed at baseline and follow-up. When age-adjusted, the D+ group showed significantly poorer performance in general cognition and some subtests regarding memory, executive function, and attention. At the 1-year follow-up, changes in the calculation test ( P = .005) and Controlled Oral Word Test (COWAT; P = .048) were significantly different between groups. Only the Di group showed significant improvement in calculation. The Dn group showed significant decrement in COWAT that was significantly different from that of the Di group, which showed no significant change. Patients with depression having MCI showed poorer cognitive function than nondepressed patients with MCI in some cognitive domains. Improvement in depression was related to improvement or prevention of decline in cognitive measures.

    To evaluate the maternal perception of their child's weight (MPCW) and perception of unrelated children's weight. Cross-sectional. Maternal and Child Nursing Health Department at 6 Units of Family Medicine. 486 dyads (mother and child under 1 year). The following question was applied: "I think my child is", and images were provided according the child's gender. Children's weight and height were measured. A total of 20.5% of the mothers of overweight (OW) children accurately perceived this situation, while none of the mothers of obese (OB) children did (κ=0.14±0.03, Z=5.36, p=.001). By images, 63.3% of mothers of OW children and 33.3% of mothers of OB children perceived this situation (κ=0.01±0.02, Z=0.73, p=.46). Most mothers selected the image of OW child as the image of a healthy child (κ=-0.04±0.01, Z=-2.65, p=.008), the image of a child under 1 year (κ=-0.01±0.02, Z=-0.86, p=.38) and the image that they would like their child to look like (κ=0.0004±0.01, Z=0.02, p=.98). The mothers do not perceive the OW-OB of their children. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    To compare the 1-year outcomes after half-top-hat (HTH) penetrating keratoplasty (PK) versus top-hat (TH) PK and regular PK. We reviewed the clinical notes of 87 consecutive patients who had undergone either HTH PK (23 eyes), TH PK (36 eyes) or regular PK (35 eyes) at Toronto Western Hospital between 2002 and 2007. We evaluated best-corrected visual acuity (BCVA), topographic and refractive results, high-order ocular aberrations, endothelial cell counts and complication rates. The three groups of patients did not differ significantly in their demographics (age, gender and laterality), donor endothelial cell counts, preoperative visual acuity or intraocular pressure (IOP). At 12 months postoperatively, BCVA was similar in the three groups, as was the mean spherical equivalent and cylinder. The time to sutures removal was significantly shorter in the HTH PK versus regular PK groups (3.8 (1.2) vs 9.7 (1.1) months, pastigmatism treated with relaxing incisions (n = 7 vs n = 2 in HTH PK) and dehiscence of wound incision (n = 2, versus n = 0 in HTH PK). BCVA and refractive results are similar after half-top-hat, top-hat and regular PK. Half-top-hat PK substantially speeds up visual recovery and contributes to significantly higher endothelial cell counts in the grafts 1 year after surgery.

    Full Text Available Executive function declines with age, but engaging in aerobic exercise may attenuate decline. One mechanism by which aerobic exercise may preserve executive function is through the up-regulation of brain-derived neurotropic factor (BDNF, which also declines with age. The present study examined BDNF as a mediator of the effects of a 1-year walking intervention on executive function in 90 older adults (mean age = 66.82. Participants were randomized to a stretching and toning control group or a moderate intensity walking intervention group. BDNF serum levels and performance on a task-switching paradigm were collected at baseline and follow-up. We found that age moderated the effect of intervention group on changes in BDNF levels, with those in the highest age quartile showing the greatest increase in BDNF after 1-year of moderate intensity walking exercise (p = .036. The mediation analyses revealed that BDNF mediated the effect of the intervention on task-switch accuracy, but did so as a function of age, such that exercise-induced changes in BDNF mediated the effect of exercise on task-switch performance only for individuals over the age of 71. These results demonstrate that both age and BDNF serum levels are important factors to consider when investigating the mechanisms by which exercise interventions influence cognitive outcomes, particularly in elderly populations.

    We assessed the probability of achieving continence and potency after robotic radical prostatectomy in elderly patients. The cohort included 1,436 robotic radical prostatectomy cases performed at our institution between 2003 and 2008. Continence (pad-free) and potency (erection sufficient for intercourse) at baseline and 1 year after surgery were evaluated by the UCLA-PCI questionnaire. Point estimates of the predicted probabilities of continence and potency for age 65, 70 and 75 years were calculated from multivariate logistic regression models adjusting for age, nerve sparing status, baseline International Prostate Symptom Score and baseline Sexual Health Inventory for Men score. Patients who were impotent before surgery or those who received hormones or radiation within 1 year after surgery were censored. Mean patient age was 60 years (range 38 to 85) with 25% older than 65 years and 77 (5%) 70 years old or older. Age (OR 0.97, p = 0.002), baseline I-PSS (OR 0.98, p = 0.02) and Sexual Health Inventory for Men scores (OR 1.02, p = 0.005) were independently associated with being pad-free.

    The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], pchildren, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Few studies on suicidal ideation have been conducted in post-stroke patients in China. This national study examined suicidal ideation at 1-year post-stroke and explored its demographic and clinical correlates. A total of 1418 patients with ischemic stroke were included in 56 hospitals nationwide. Demographic, clinical characteristics and neuro-imaging information were collected with standardized instruments, including assessment of stroke severity, depression, cognitive impairment, stroke recurrence, physical disability and insomnia. Suicidal ideation was measured using item 3 of the Hamilton Rating Scale for Depression. The frequency of suicidal ideation in this study was 6.6%. Multivariate analyses revealed that disability (OR=2.07, 95% CI=1.09-3.05), stroke recurrence (OR=4.13, 95% CI=1.74-9.77) and insomnia early (OR=1.87, 95% CI=1.03-3.39), middle (OR=2.66, 95% CI=1.46-4.85) and late (OR=2.35, 95% CI=1.31-4.19) at the 1-year follow-up and post-stroke depression (OR=2.16, 95% CI=1.23-3.82) were significantly associated with post-stroke suicidal ideation. Post-stroke depression, disability, insomnia and stroke recurrence are possible risk factors of suicidal ideation that warrant attention in clinical practice. Copyright © 2016 Elsevier Inc.

    To assess the effects of Hurricane Katrina on mortality, morbidity, disease prevalence, and service utilization during 1 year in a cohort of 20,612 older adults who were living in New Orleans, Louisiana, before the disaster and who were enrolled in a managed care organization (MCO). Observational study comparing mortality, morbidity, and service use for 1 year before and after Hurricane Katrina, augmented by a stratified random sample of 303 enrollees who participated in a telephone survey after Hurricane Katrina. Sources of data for health and service use were MCO claims. Mortality was based on reports to the MCO from the Centers for Medicare & Medicaid Services; morbidity was measured using adjusted clinical groups case-mix methods derived from diagnoses in ambulatory and hospital claims data. Mortality in the year following Hurricane Katrina was not significantly elevated (4.3% before vs 4.9% after the hurricane). However, overall morbidity increased by 12.6% (P Hurricane Katrina on this vulnerable population. Although quick rebuilding of the provider network may have attenuated more severe health outcomes for this managed care population, new policies must be introduced to deal with the health consequences of a major disaster.

    The authors studied a range of preoperative factors for their predictive value of effectiveness of Lap-Band placement, using the percentage of excess weight loss at 1-year as the outcome measure (%EWL1). All factors were measured and recorded prior to surgery. Factors included: patient demographics, family, medical and weight history. Laboratory measures and the responses to the SF-36 Health Survey were also assessed. Factors were assessed for correlation with %EWL1. The group (N=440, F:M 383:57) had mean age 40.0+/-9.5 years, weight of 126+/-25 kg, and BMI 45.6+/-7.5 kg/m2 pre-operatively. At 1-year follow-up, the group had mean weight 97.6obesity. Important physical factors have been found to influence the rate of weight loss. Those with increased age, pain, physical disability and insulin resistance have a great deal to gain from weight loss. Although this study has identified factors that are associated with less weight loss, we have not found any factor that predicts an unacceptably low weight loss and thus provides a contraindication to Lap-Band placement. The findings of this study allow us to set more realistic goals for the rate of weight loss in specified sub-groups of our patients.

    In cariously exposed immature permanent teeth, the treatment choice is controversial in pediatric dentistry. Radical root canal treatment usually appears to be the solution for these teeth. Even partial pulpotomy is a vital treatment for traumatically exposed immature permanent teeth; extending the borders of indication towards cariously exposed immature permanent teeth with reversible pulpitis may abolish the necessity of pulpectomy. This article describes the partial pulpotomy of a cariously affected immature permanent teeth and the follow-up for 1 year. A healthy 11-year-old male patient was referred to Gazi University Faculty of Dentistry Department of Pediatric Dentistry. The patient had reversible pulpitis symptoms on teeth numbered 45. At radiographic examination, immature apex and deep caries lesion were observed and partial pulpotomy was performed by using calcium hydroxide to maintain vitality of the pulp and allow continued development of root dentin expecting the root will attain full maturity. Clinical and radiographic follow-up demonstrated a vital pulp besides not only closure of the apex (apexogenesis), but also physiologic root development (maturogenesis) after 1 year. Partial pulpotomy is an optional treatment for cariously exposed immature permanent teeth for preserving vitality and physiological root development. PMID:24324899

    To estimate the probability of successful sterilization after an hysteroscopic or laparoscopic sterilization procedure. An evidence-based clinical decision analysis using a Markov model was performed to estimate the probability of a successful sterilization procedure using laparoscopic sterilization, hysteroscopic sterilization in the operating room, and hysteroscopic sterilization in the office. Procedure and follow-up testing probabilities for the model were estimated from published sources. In the base case analysis, the proportion of women having a successful sterilization procedure on the first attempt is 99% for laparoscopic sterilization, 88% for hysteroscopic sterilization in the operating room, and 87% for hysteroscopic sterilization in the office. The probability of having a successful sterilization procedure within 1 year is 99% with laparoscopic sterilization, 95% for hysteroscopic sterilization in the operating room, and 94% for hysteroscopic sterilization in the office. These estimates for hysteroscopic success include approximately 6% of women who attempt hysteroscopically but are ultimately sterilized laparoscopically. Approximately 5% of women who have a failed hysteroscopic attempt decline further sterilization attempts. Women choosing laparoscopic sterilization are more likely than those choosing hysteroscopic sterilization to have a successful sterilization procedure within 1 year. However, the risk of failed sterilization and subsequent pregnancy must be considered when choosing a method of sterilization.

    Full Text Available Sanfujiu is a treatment method of applying herbal paste onto the acupoints Fengmen and Feishu during the three hottest days of summer to treat patients with allergies. The objectives of this study were to determine the treatment efficacy at 1 year after the Sanfujiu treatment, and examine variations in the perceived efficacy of Sanfujiu among different subgroups, based on the patients' ages, diagnoses and number of reactive symptoms immediately after the treatment. We enrolled 105 patients who completed Sanfujiu treatment at a medical university hospital in Taipei as the subjects. One year after treatment, trained interviewers conducted telephone interviews with the patients. Approximately 60% of them perceived the treatment as being effective at 1 year later, which was higher than that at 1 week after treatment (45.7%. Younger subjects (<19 years of age and patients with asthma were more likely to report the treatment as being effective. Patients who had more reactive symptoms after the third Sanfujiu treatment were more likely to report the treatment as being effective. The results demonstrated that Sanfujiu was moderately effective, as perceived by patients in Taiwan, in treating their allergic symptoms.

    Objective To establish normal, trimester-specific reference intervals for serum 17β-estradiol, progesterone (P), 17α-hydroxyprogesterone, cortisol, 11-deoxycortisol, androstenedione, DHEA, and DHEAS, measured simultaneously using isotope dilution tandem mass spectrometry. Design Sequential cohort study. Patient(s) Healthy women undergoing a normal pregnancy (age, 25–38 years; mean, 30 years) attending a prenatal well clinic at gestation weeks 12, 22, and 32 and approximately 1 year postpartum. Main Outcome Measure(s) Trimester-specific reference intervals of endogenous steroid hormones analyzed using an isotope dilution tandem mass spectrometer equipped with an atmospheric pressure photoionization source with deuterium-labeled internal standards. Result(s) Serum estradiol, P, 17α-hydroxyprogesterone, and 11-deoxycortisol increased throughout pregnancy; cortisol increased up to the second trimester and then remained steady, while androstenedione increased by 80 percent by gestation week 12, then remained constant. Serum DHEA-S decreased by 50% by the third trimester. Conclusion(s) Trimester-specific reference intervals are reported for eight serum steroids. The ratios of individual serum hormone concentrations during pregnancy relative to their 1-year postpartum concentrations illustrate the expected normal trends of changes in hormone concentrations during pregnancy.

    A live attenuated yellow fever (YF) vaccination is required of all travellers visiting countries where YF virus is endemic. Although the risk of serious adverse events (AEs) after YF vaccination is known to be greater in elderly people than in younger people, information about other AEs among elderly travellers is lacking. A prospective observational questionnaire study was conducted to investigate the occurrence of AEs after YF vaccination in travellers who attended a designated YF vaccination centre in Tokyo, Japan, from 1 November 2011 to 31 October 2012. A questionnaire enquiring about any AEs experienced in the 2 weeks following YF vaccination was distributed to all vaccinees enrolled in this study, and responses were collected subsequently by mail or phone. For child vaccinees, their parents were allowed to respond in their stead. Of the 1298 vaccinees who received the YF vaccine, 1044 (80.4%) were enrolled in the present study and 666 (63.8%) responded to the questionnaire. Of these 666 respondents, 370 (55.6%) reported AEs, of which 258 (38.7%) were systemic and 230 (34.5%) were local. No severe AEs associated with YF vaccination were reported. Elderly vaccinees (aged ≥60 years) reported fewer total AEs than those aged yellow vaccination reported among elderly vaccinees than among non-elderly vaccinees. These results could provide supplementary information for judging the adaptation of vaccination in elderly travellers. © International Society of Travel Medicine, 2016. All rights reserved.

    Proteinuria is associated with reduced kidney allograft survival. Herein we assessed the association between proteinuria, graft histology and survival. The cohort included 613 kidney allograft recipients who had proteinuria (measured) and surveillance biopsies at 1-year posttransplant. Proteinuria >150 mg/day was detected in 276 patients (45%) and in 182 of these, proteinuria was below 500. In >84% of patients even low levels of proteinuria were associated with albuminuria. Proteinuria was associated with the presence of graft glomerular pathology and the use of sirolimus. Eighty percent of patients with proteinuria >1500 mg/day had glomerular pathology on biopsy. However, lower levels of proteinuria were not associated with specific pathologies at 1 year. Compared to no sirolimus, sirolimus use was associated with higher prevalence of proteinuria (40% vs. 76%, p Proteinuria was associated with reduced graft survival (HR = 1.40, p = 0.001) independent of other risk factors including, glomerular pathology, graft function, recipient age and acute rejection. The predominant pathology in lost allografts (n = 57) was glomerular, particularly in patients with 1-year proteinuria >500. Thus, proteinuria, usually at low levels (proteinuria relate to poor graft survival. Proteinuria and glomerular pathology relate independently to survival.

    Hepatocellular carcinoma (HCC) is a dismal tumor with a high incidence, prevalence and poor prognosis and survival. Management of HCC necessitates multidisciplinary clinics due to the wide heterogeneity in its presentation, different therapeutic options, variable biologic behavior and background presence of chronic liver disease. We studied the different prognostic factors that affected survival of our patients to improve future HCC management and patient survival. This study is performed in a specialized multidisciplinary clinic for HCC in Kasr El Eini Hospital, Cairo University, Egypt. We retrospectively analyzed the different patient and tumor characteristics and the primary mode of management applied to our patients. Further analysis was performed using univariate and multivariate statistics. During the period February 2009 till February 2013, 290 HCC patients presented to our multidisciplinary clinic. They were predominantly males and the mean age was 56.5 ± 7.7 years. All cases developed HCC on top of cirrhosis that was mainly due to HCV (71%). Most of our patients were Child-Pugh A (50%) or B (36.9%) and commonly presented with small single lesions. Transarterial chemoembolization was the most common line of treatment used (32.4%). The overall survival was 79.9% at 6 months, 54.5% at 1 year and 22.4% at 2 years. Serum bilirubin, site of the tumor and type of treatment were the significant independent prognostic factors for survival. Our main prognostic variables are the bilirubin level, the bilobar hepatic affection and the application of specific treatment (either curative or palliative). Multidisciplinary clinics enhance better HCC management.

    An association is observed between the severity of myotonic dystrophy type 1 (DM1) and the genetic abnormality of cytosine-thymine-guanine (CTG) repeat expansion. It is unknown whether an association exists between survival and CTG repeat expansion. In an adult 406-patient DM1 cohort, the phenotype, including survival age, was evaluated in relation to CTG repeat expansion. At study entry, age was 42 ± 12 (range 18-78) years, with a CTG repeat length of 629 ± 386 (range 54-1965). An inverse correlation was observed between CTG repeat length and the age at onset and younger DM1 phenotype. Over a follow-up of 9.2 ± 3.1 years, 118 (29.1%) patients died, including 60 of neuromuscular respiratory failure, 41 of cardiac causes, and 17 of non-neuromuscular, non-cardiac causes. There was an inverse relationship between all-cause survival and CTG length (relative risk 5.4 per log repeat, 95% confidence interval 2.9-10.2, P < 0.001). The data demonstrate a genotype-mortality association in DM1. Copyright © 2010 Wiley Periodicals, Inc.

    There are different opinions about the effects of growth hormone replacement therapy (GHRT) on thyroid function and volume. This study aimed to assess the effects of GHRT on thyroid volume and function in the children and adolescents with growth hormone (GH) deficiency. A total of 29 patients diagnosed with GH deficiency were enrolled in the study. The control group consisted of 29 cases matched for age, gender and pubertal period with the patients. Thyroid function tests and insulin-like growth factor levels were measured, simultaneously thyroid volumes were assessed by ultrasonography at the initiation period and at the end of GHRT. Thyroid volumes of the patient group was -0.55±1.1 standard deviations (SDs) initially; whereas at the end of 1 year it was found to be -0.29±1.29 SDs and both SDs of thyroid volumes did not differ significantly. The SDs of thyroid volume of the control group was -0.85±1.03 SDs initially and -0.72±0.85 SDs at the end of 1 year; and they did not differ significantly. On the other hand, after GHRT of 1 year, thyroid stimulating hormone (TSH) and free thyroxine (T4) levels decreased. It was observed that SDs of thyroid gland volumes did not change in GH deficient children and adolescents after GHRT.

    Increasing numbers of women experience pregnancy around the time of, or after, a diagnosis of breast cancer. Understanding the effect of pregnancy on survival in women with breast cancer will help in the counseling and treatment of these women. To compare the overall survival of women diagnosed with breast cancer during pregnancy or in the postpartum period with that of women who had breast cancer but did not become pregnant. This population-based, retrospective cohort study linked health administrative databases in Ontario, Canada, comprising 7553 women aged 20 to 45 years at the time of diagnosis with invasive breast cancer, from January 1, 2003, to December 31, 2014. Any pregnancy in the period from 5 years before, until 5 years after, the index date of the diagnosis of breast cancer. Women were classified into the following 4 exposure groups: no pregnancy (the referent), pregnancy before breast cancer, pregnancy-associated breast cancer, and pregnancy following breast cancer. Five-year actuarial survival rates for all exposure groups, age-adjusted and multivariable hazard ratios [HRs] of pregnancy for overall survival for all exposure groups, and time-dependent hazard ratios for women with pregnancy following breast cancer. Among the 7553 women in the study (mean age at diagnosis, 39.1 years; median, 40 years; range, 20-44 years) the 5-year actuarial survival rate was 87.5% (95% CI, 86.5%-88.4%) for women with no pregnancy, 85.3% (95% CI, 82.8%-87.8%) for women with pregnancy before breast cancer (age-adjusted hazard ratio, 1.03; 95% CI, 0.85-1.27; P = .73), and 82.1% (95% CI, 78.3%-85.9%) for women with pregnancy-associated breast cancer (age-adjusted hazard ratio, 1.18; 95% CI, 0.91-1.53; P = .20). The 5-year actuarial survival rate was 96.7% (95% CI, 94.1%-99.3%) for women who had pregnancy 6 months or more after diagnosis of breast cancer, vs 87.5% (95% CI, 86.5%-88.4%) for women with no pregnancy) (age-adjusted HR, 0.22; 95% CI, 0.10-0.49; P

    Full Text Available Pediatric uptake and outcomes in antiretroviral treatment (ART programmes have lagged behind adult programmes. We describe outcomes from a population-based pediatric ART cohort in rural southern Malawi.Data were analyzed on children who initiated ART from October/2003 -September/2011. Demographics and diagnoses were described and survival analyses conducted to assess the impact of age, presenting features at enrolment, and drug selection.The cohort consisted of 2203 children <15 years of age. Age at entry was <1 year for 219 (10%, 1-1.9 years for 343 (16%, 2-4.9 years for 584 (27%, and 5-15 years for 1057 (48% patients. Initial clinical diagnoses of tuberculosis and wasting were documented for 409 (19% and 523 (24% patients, respectively. Median follow-up time was 1.5 years (range 0-8 years, with 3900 patient-years of follow-up. Over the period of observation, 134 patients (6% died, 1324 (60% remained in the cohort, 345 (16% transferred out, and 387 (18% defaulted. Infants <1 year of age accounted for 19% of deaths, with a 2.7-fold adjusted mortality hazard ratio relative to 5-15 year olds; median time to death was also shorter for infants (60 days than older children (108 days. Survival analysis demonstrated younger age at ART initiation, more advanced HIV stage, and presence of tuberculosis to each be associated with shorter survival time. Among children <5 years, severe wasting (weight-for-height z-score survival.Cumulative incidence of mortality was 5.2%, 7.1% and 7.7% after 1, 3, and 5 years, respectively, with disproportionate mortality in infants <1 year of age and those presenting with tuberculosis. These findings reinforce the urgent need for early diagnosis and treatment in this population, but also demonstrate that provision of pediatric care in a rural setting can yield outcomes comparable to more resourced urban settings of poor countries.

    To determine the relative efficacy and complications of the Ahmed glaucoma valve (AGV) model FP7 (New World Medical, Ranchos Cucamonga, CA) and the Baerveldt glaucoma implant (BGI) model 101-350 (Abbott Medical Optics, Abbott Park, IL) in refractory glaucoma. Multicenter, randomized, controlled clinical trial. Two hundred seventy-six patients, including 143 in the AGV group and 133 in the BGI group. Patients 18 to 85 years of age with refractory glaucoma having intraocular pressure (IOP) of 18 mmHg or more in whom an aqueous shunt was planned were randomized to undergo implantation of either an AGV or a BGI. The primary outcome was failure, defined as IOP >21 mmHg or not reduced by 20% from baseline, IOP ≤5 mmHg, reoperation for glaucoma or removal of implant, or loss of light perception vision. Secondary outcomes included mean IOP, visual acuity, use of supplemental medical therapy, and complications. Preoperative IOP (mean±standard deviation [SD]) was 31.2±11.2 mmHg in the AGV group and 31.8±12.5 mmHg in the BGI group (P = 0.71). At 1 year, mean±SD IOP was 15.4±5.5 mmHg in the AGV group and 13.2±6.8 mmHg in the BGI group (P = 0.007). The mean±SD number of glaucoma medications was 1.8±1.3 in the AGV group and 1.5±1.4 in the BGI group (P = 0.071). The cumulative probability of failure was 16.4% (standard error [SE], 3.1%) in the AGV group and 14.0% (SE, 3.1%) in the BGI group at 1 year (P = 0.52). More patients experienced early postoperative complications in the BGI group (n = 77; 58%) compared with the AGV group (n = 61; 43%; P = 0.016). Serious postoperative complications associated with reoperation, vision loss of ≥2 Snellen lines, or both occurred in 29 patients (20%) in the AGV group and in 45 patients (34%) in the BGI group (P = 0.014). Although the average IOP after 1 year was slightly higher in patients who received an AGV, there were fewer early and serious postoperative complications associated with the use of the AGV than the BGI.

    Most studies on post-stroke depression (PSD) have focused on a certain time point after stroke instead of the time course of PSD. The aim of this study was to determine the relationship between frontal lobe lesions, course of PSD over a year following the stroke onset, and the 1-year prognosis in patients with first-ever ischemic stroke. A total of 1067 patients from the prospective cohort study on the incidence and outcome of patients with post stroke depression in China who were diagnosed with first-ever ischemic stroke and attended 4 follow-up visits at 14±2 days, 3 months, 6 months, and 1 year after stroke onset, were enrolled in the study. PSD was diagnosed according to DSM-IV. The course of PSD was divided into the following two categories: persistent/recurrent depression and no/transient depression. Patients with any ischemic lesion responsible for the indexed stroke event located in the frontal lobe were defined as patients with frontal lobe lesions. Modified Rankin Scale (mRS) ≥2 at 1-year was considered to be poor prognosis. There were 109 patients with and 958 patients without frontal lobe lesions that formed the frontal lobe (FL) and no-frontal lobe (NFL) groups, respectively. After adjusting for confounding variables, frontal lobe lesion was significantly associated with persistent/recurrent PSD (OR 2.025, 95%CI 1.039-3.949). Overall, 32.7% of patients in the FL group had poor prognosis at 1- year compared with 22.7% in the NFL group (P = 0.021). Compared with no/transient depression, persistent/recurrent depression was found to be an independent predictor of poor prognosis at 1-year both in FL and NFL groups. Long-term and periodical screening, evaluation and treatment are needed for PSD after the onset of ischemic stroke, particularly for patients with frontal lobe infarction.

    To evaluate the residual effects of fitness and whole-body vibration (WBV) training in older men 1 year after completion of the interventions. A 1-year follow-up of a randomized controlled trial comparing the effects of 1 year of fitness training, including combined resistance and aerobic (R+A) training and WBV training, with a control (CON) group. University training center. Adult men (N=72) between 60 and 80 years of age. Response rate was 80%, 92%, and 90% in the R+A training (n=20), WBV training (n=23), and CON (n=29) groups, respectively. The intervention groups exercised 3 times weekly during 1 year. The R+A training group performed a standard training program, combining resistance exercises and aerobic training, following the American College of Sports Medicine guidelines. The WBV training group performed unloaded static and dynamic leg exercises on a vibration platform. The CON group did not participate in any training program. Muscle volume, isometric and concentric muscle strength, muscle quality, and muscle power. Both interventions had resulted in comparable increases in muscle quality characteristics. No significant changes had been found in the CON group. During the 1-year follow-up period, the R+A (-4.05%, P=.006) and WBV (-2.45%, Pmuscle volume. However, isometric muscle strength was preserved in the R+A training group (+1.65%, P=.745), resulting in an increase in muscle quality (+7.97%, P=.034). In the WBV training group, muscle power decreased (-6.10%, Pmuscle power, no significant changes were found in the CON group. One year of R+A and/or WBV training can equally reverse the adverse effects of aging on muscle quality in older men, but their residual impact after follow-up is different.

    We measured IgA and IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) in sera from 203 1-year-old children who had received one to three doses of a monocomponent PT toxoid vaccine. Ten children (5%) had IgA antibody to PT indicating recent infection; seven of these children...... had received three doses of vaccine. PT IgA responders did not have significantly longer coughing episodes than PT IgA non-responders. Since an IgA antibody response occurs in only approximately 50% of infected children, the actual infection rate in our cohort is estimated to approximately 10......%. The apparent high Bordetella pertussis infection rate in Danish infants suggests that the monocomponent PT toxoid vaccine used in Denmark has limited efficacy against B. pertussis infection.

    The present study addresses the consequences of cognitive disturbances on symptomatic outcome. Fifty-three first-episode schizophrenics were reassessed (n = 32) 1 year after admission. Simple regression analyses revealed that several self-perceived cognitive deficits at baseline as measured with the Frankfurt Complaint Questionnaire significantly predicted increased Brief Psychiatric Rating Scale global scores at follow-up (p = 0.05 to p = 0.005). A stepwise regression analysis proved memory dysfunction to be the strongest predictor of symptomatic worsening (p = 0.005). It is suggested that the exploration and treatment of neuropsychological deficits in schizophrenia is of great clinical importance with regard to its impact on both functional and symptomatic outcome in schizophrenia.

    Kidneys from elderly deceased patients and otherwise marginal donors may be considered for transplantation and a pretransplantation histopathological score for prediction of postoperative outcome is warranted. In a retrospective design, 29 baseline renal needle biopsies from elderly deceased donors...... wall thickness of arteries and/or arterioles. Nineteen renal baseline biopsies from 15 donors (age: 64 ± 10 years) were included and following consensus the histopathological score was 4.3 ± 2.1 (intraclass correlation coefficient: 0.81; confidence interval: 0.66-0.92). The donor organs were used...... for single renal transplantation (recipient age: 47 ± 3 years). Two grafts were lost after the transplantation. In the remaining 17 recipients the 1-year creatinine clearance (54 ± 6 mL/min) correlated to the baseline histopathological score (r(2) = 0.59; p

    Predicting outcome in weight loss trials from baseline characteristics has proved difficult. Readiness to change is typically measured by self-report. Performance of a behavioral task, completion of food records, from the screening period in the Look AHEAD study (n = 549 at four clinical centers) was assessed. Completeness of records was measured by the number of words and Arabic numerals (numbers) recorded per day, the number of eating episodes per day, and days per week where physical activity was noted. The primary outcome was weight loss at one year. In univariable analysis, both the number of words recorded and the number of numbers recorded were associated with greater weight loss. In multivariable analysis, individuals who recorded 20-26, 27-33, and ≥34 words per day lost 9.12%, 11.40%, and 12.08% of initial weight, compared to 8.98% for individuals who recorded less than 20 words per day (P values of 0.87, 0.008, and <0.001, respectively, compared to <20 words per day). Participants who kept more detailed food records at screening lost more weight after 1 year than individuals who kept sparser records. The use of objective behavioral screening tools may improve the assessment of weight loss readiness. Copyright © 2013 The Obesity Society.

    It has been suggested that for success with immediate loaded dental implants it is necessary that, prior to their placement, bone quantity and quality as well as the biomechanical environment in which the implants are to function be evaluated. However, conventional techniques currently used for immediate implant placement lack sufficient precision and are usually accomplished by opening flap procedures. The purpose of this paper is to report the benefit of sophisticated pre-operative diagnostic implant planning and a flapless surgical approach with immediate loading. The report describes the use of computed tomography (CT) for three-dimensional (3D) evaluations of bone implant sites, an interactive software program for 3D planning and the fabrication of stereolithographic models as custom surgical templates. The degree of patient satisfaction was evaluated by periodic recall and by adopting a specially designed analogue scale in each visit. The mean amount of bone loss around the implants was 0.5 +/- 0.1 mm and the satisfactoriness scale was rated high (i.e. 81), at the end of 1 year. The use of stereolithographic appliances in accordance with flapless surgery makes immediate placement of the implants more predictable.

    Moderate to severe traumatic brain injuries can negatively influence health-related quality of life (HRQOL) in adolescent patients. The effect of sport-related concussion on adolescent HRQOL remains unclear. To investigate the perceptions of adolescent student-athletes and their parents regarding the adolescents' HRQOL 1 year after sport-related concussion. Qualitative study. Secondary school. Seven adolescent student-athletes (age range, 12-16 years) who sustained a sport-related concussion at least 1 year (15.3 ± 2.8 months) before the study participated along with their primary care-giving parents (n = 7). Fourteen semistructured face-to-face interviews (7 adolescents, 7 parents) were completed. Interviews were transcribed and inductively analyzed by a team of 3 athletic trainers with 32 combined years of professional experience. Themes were negotiated through a consensual review process. Participant checks were completed to ensure trustworthiness of the results. Four major themes emerged from the interviews: (1) significant effect of symptoms, (2) feelings of frustration, (3) influence on school attendance and activities, and (4) nature of interpersonal and team relationships. Participants indicated that the physical symptoms of the concussion substantially affected their emotional and academic function. The influence of the concussion on social interactions seemed to depend on the nature of interpersonal relationships. Sport-related concussion can negatively influence physical and emotional function, academics, and interpersonal interactions as perceived by adolescent student-athletes and their parents. Education of parents and their children, school professionals, coaches, and teammates remains critical to effectively recognize and manage sport-related concussion. Secondary school districts also play a critical role in the concussion-management process by establishing and implementing accommodation policies that alleviate student concerns about falling

    Excess weight may be related to the development of adverse cardiometabolic risk factors in children. The aim of this study was to evaluate the effect of a lifestyle intervention program (nutrition and exercise counseling) on anthropometric parameters and metabolic syndrome (MS) components in Portuguese overweight/obese children. A total of 83 overweight/obese children aged 7-9 years were assigned to a 1-year individual or group-based treatment (GT); 61 children (z-score BMI (zBMI): 1.93 ± 0.28; 27 boys and 34 girls) completed the program. Anthropometric and biochemical parameters were assessed at baseline, at 6 months and at 1 year. The overweight/obese children, compared to normal-weight ones, presented significantly higher blood pressure, total-cholesterol, total-cholesterol/high density lipoprotein cholesterol (HDL) ratio, triglycerides, Apolipoprotein B and C-reactive protein levels, while HDL and Apolipoprotein A-I were significantly lower. At baseline, the prevalence of MS was 16.4% in overweight/obese and 0% in normal-weight children. The number of components of MS was significantly higher in children with higher zBMI. Lifestyle intervention led to a significant improvement in zBMI, waist circumference/height ratio, HDL, triglycerides, Apolipoprotein A-I, and Apolipoprotein B levels. The prevalence of MS decreased to 14.8%. The GT intervention seems to be more successful, with a significant decrease in zBMI and an increase in HDL and a lower drop-out rate. Overweight/obese children have multiple risk factors associated with the MS. Lifestyle intervention, both individual and group-based treatment, led to an improvement in the degree of overweight/obesity and in MS components.

    Full Text Available The vast majority of Americans do not engage in adequate regular physical activity despite its well-known health benefits. Even when individuals attempt to become more active by joining a fitness center, estimates suggest that nearly half terminate their membership within the first 6 months. A better understanding of who is at risk for early membership termination upon joining may help researchers develop targeted interventions to improve the likelihood that individuals will successfully maintain memberships and physical activity. This study's purpose was to identify, based on a wellness assessment (WA used in fitness centers, individuals at risk for fitness membership termination prior to 1-year. Center members (N = 441; Mage = 41.9, SD = 13.1; 74.4% female completed a comprehensive WA of stress, life satisfaction, physical fitness, metabolic health, and sleep quality at the beginning of their memberships and were followed for one year. Latent class analyses utilized the WA to identify four groups: (a healthy, (b unhealthy, (c poor psychological wellness, and (d poor physical wellness. Participants in the poor psychological wellness group (OR = 2.24, p = 0.007 and the unhealthy group (OR = 2.40, p = 0.037 were significantly more likely to terminate their memberships at 1-year as compared to the healthy group. Participants with poor physical wellness visited the fitness center less frequently than healthy participants (p < 0.01. Results suggest that poor psychological wellness is a risk factor for terminating memberships, whereas poor physical wellness is not. Future studies should replicate these latent classes and develop targeted interventions to address psychological wellness as a method to improve fitness membership retention.

    Early adolescent girls' rates of drug use have matched, and in some instances, surpassed boys' rates. Though girls and boys share risk factors for drug use, girls also have gender-specific risks. Tailored interventions to prevent girls' drug use are warranted. This study developed and tested a web-based, drug abuse prevention program for adolescent girls. The nationwide sample of 13- and 14-year-old girls (N = 788) was recruited via Facebook ads. Enrolled girls were randomly assigned to the intervention or control condition. All girls completed pretest measures online. Following pretest, intervention girls interacted with the 9-session, gender-specific prevention program online. The program aimed to reduce girls' drug use and associated risk factors by improving their cognitive and behavioral skills around such areas as coping with stress, managing mood, maintaining a healthy body image, and refusing drug use offers. Girls in both conditions again completed measures at posttest and 1-year follow-up. At posttest, and compared to girls in the control condition, girls who received the intervention smoked fewer cigarettes and reported higher self-esteem, goal setting, media literacy, and self-efficacy. At 1-year follow-up, and compared to girls in the control condition, girls who received the intervention reported engaging in less binge drinking and cigarette smoking; girls assigned to the intervention condition also had higher alcohol, cigarette, and marijuana refusal skills, coping skills, and media literacy and lower rates of peer drug use. This study's findings support the use of tailored, online drug abuse prevention programming for early adolescent girls.

    This is a prospective randomized and controlled study, approved by the local ethical committee of Saarland (Germany). The aim of the current study was to analyze segmental motion following artificial disc replacement using disc prosthesis over 1 year. A second aim was to compare both segmental motion as well as clinical result to the current gold standard (anterior cervical discectomy and fusion [ACDF]). ACDF may be considered to be the gold standard for treatment of symptomatic degenerative disc disease within the cervical spine. However, fusion may result in progressive degeneration of the adjacent segments. Therefore, disc arthroplasty has been introduced. Among these, artificial disc replacement seems to be promising. However, segmental motion should be preserved. This, again, is very difficult to judge and has not yet been proven. A total of 49 patients with cervical disc herniation were enrolled and assigned to either study group (receiving a disc prosthesis) or control group (receiving ACDF, using a cage with bone graft and an anterior plate). Roentgen stereometric analysis (RSA) was used to quantify intervertebral motion immediately as well as 3, 6, 12, 24, and 52 weeks after surgery. Also, clinical results were judged using visual analog scale and neuro-examination at even RSA follow-up. Cervical spine segmental motion decreased over time in the presence of disc prosthesis or fusion device. However, the loss segmental motion is significantly higher in the fusion group, when looked at 3, 6, 12, 24, and 52 weeks after surgery. We observed significant pain reduction in neck and arm after surgery, without significant difference between both groups. Cervical spine disc prosthesis remains cervical spine segmental motion within the first 1 year after surgery. The clinical results are the same when compared with the early results following ACDF.

    To evaluate the efficacy and safety of the multifocal excimer laser corneal ablation profile (the Supracor procedure) in hyperopic presbyopia 1 year after laser treatment. This prospective, consecutive, one-center, cross-sectional study included 20 patients with hyperopic presbyopia 1 year after treatment with the Supracor procedure. The main outcome measures were monocular uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA), photopic contrast sensitivity (Pelli-Robson charts), patient satisfaction, and functioning at 12 months. Thirty-nine eyes of 20 patients (mean age 59 ± 7.2 years) were treated. Mean UDVA improved from 0.56 ± 0.31 (mean 0.34 logMAR) preoperatively to 0.9 ± 0.15 (mean 0.06 logMAR) 12 months after surgery. Mean UNVA increased from 0.15 ± 0.07 (mean 0.84 logMAR) before surgery to 0.62 ± 0.24 (mean 0.23 logMAR) 12 months after treatment. Four eyes lost 2 lines of corrected distance visual acuity (10.3%). Monocular photopic contrast sensitivity was within age-correlated normal range (Pelli-Robson chart, mean contrast sensitivity 1.83 ± 0.18). A total of 75% of the patients would undergo Supracor again (1 not, 4 perhaps). The most frequently reported side effects were increased glare, reduced distance vision, and fluctuations in vision. Most patients used artificial tears. One year after Supracor, UDVA and UNVA improved markedly, photopic contrast sensitivity was in normal age-correlated range, and the majority of patients (75%) was satisfied with the results. Side effects like loss of distance vision, fluctuations of vision, and increased glare have a greater influence on patient satisfaction than the improvement of spectacle-free near vision.

    Emerging evidence suggests that implant therapy may be a viable option for diabetic individuals with elevated glycemic levels. The purpose of this 2 year observational study was to evaluate survival and clinical complications of dental implants following placement in type 2 diabetes individuals having poor glycemic control. Adult participants (n = 24) with poorly controlled type 2 diabetes (8.0% ≤ HbA1c ≤ 12.0%) received two or more transgingival dental implants. Survival was evaluated after 1 (23 participants, 72 implants) and 2 (20 participants, 59 implants) years. Clinical complications were evaluated in 18 participants (52 implants) after 21-34 months. Relationships between complications and stratified HbA1c levels were assessed using Pearson's correlation test. Survival rates were 98.6% (71/72 implants) after 1 year and 96.6% (57/59 implants) after 2 years. Complications were identified in 29% of participants with peri-implant mucositis, the most common event. Complications correlated directly with number of implants across HbA1c strata (0.42, R2  = 0.66). There was no correlation between HbA1c and the occurrences of complications or mucositis. This 2-year evaluation supports the broader application of implant therapy in type 2 diabetes individuals with poor glycemic control in demonstrating high survival rates with limited complications. © 2016 Wiley Periodicals, Inc.

    in other months of the year (VII). Evidence reveals a volume-outcome relationship regarding postoperative mortality in colonic cancer (IV) and the most recent literature suggests that it probably also is so in rectal cancer. However, volume may be a surrogate marker or proxy for other important structural factors such as quality and capacity of intensive care units, the availability of other clinical services like cardiac care units, multiple medical specialties, multidisciplinary infrastructure and nurse staffing, etc. Postoperative mortality after emergency surgery for colonic cancer was as high as 22% in 2001-2005 and mortality was significantly associated with the postoperative course. Patients developing medical complications had a mortality rate of 57.8%. Independent risk factors for death within 30 days after surgery were age ≥ 71 years, male gender, ASA grade ≥ III, palliative outcome, free or iatrogenic tumour perforation, splenectomy, intraoperative surgical adverse events and postoperative medical complications (VIII). SEMS placement performed on the indication acute bowel obstruction in patients with potentially curable disease can be accomplished with high technical and clinical success rates. The perforation rate, however, may reach 12%. Even so, the mortality rate within 30 days after a SEMS attempt and later surgery may, irrespective of its timing, by very low (3%) relative to the mortality seen after emergency surgery (IX). Long-term survival. The 5-year relative survival improved by 9% for both colonic and rectal cancer from 1977-1982 to 1995-1999 (I). Further improvement has been observed and in 2004-2006, the 5-year relative survival from colonic cancer was 52% (95% CI 51-54) for men and 57% (95% CI 55-58) for women. For rectal cancer the corresponding percentages were 55% (95% CI 53-57) and 57% (95% CI 55-59) (202). Overall, from 1977 until 2006, 1-year and 5-year survival increased almost 0.5-1% annually.

    Poultry farming has been touted as one of the major ways by which poverty can be reduced in low-income economies like Ghana. Yet, anecdotally there is a high failure rate among these poultry farms. This current study seeks to understand the relationship between network ties and survival chances...... of small commercial poultry farms (SCPFs). We utilize data from a 2-year network survey of SCPFs in rural Ghana. The survival of these poultry farms are modelled using a lagged probit model of farms that persisted from 2014 into 2015. We find that network ties are important to the survival chances...... but this probability reduces as the number of industry ties increases but moderation with dynamic capability of the firm reverses this trend. Our findings show that not all network ties aid survival and therefore small commercial poultry farmers need to be circumspect in the network ties they cultivate and develop....

    Green roofs as one of the components of water-sensitive urban design have become widely used in recent years. This paper describes performance monitoring of four prototype-scale experimental green roofs in a northern suburb of Adelaide, South Australia, undertaken over a 1-year period. Four species of indigenous Australian ground cover and grass species comprising Carpobrotus rossii, Lomandra longifolia 'Tanika,' Dianella caerula 'Breeze' and Myoporum parvifolium were planted in extensive and intensive green roof configurations using two different growing media. The first medium consisted of crushed brick, scoria, coir fibre and composted organics while the second comprised scoria, composted pine bark and hydro-cell flakes. Plant growth indices including vertical and horizontal growth rate, leaf succulence, shoot and root biomasses, water use efficiency and irrigation regimes were studied during a 12-month period. The results showed that the succulent species, C. rossii, can best tolerate the hot, dry summer conditions of South Australia, and this species showed a 100% survival rate and had the maximum horizontal growth rate, leaf succulence, shoot biomass and water use efficiency. All of the plants in the intensive green roofs with the crushed brick mix media survived during the term of this study. It was shown that stormwater can be used as a source of irrigation water for green roofs during 8 months of the year in Adelaide. However, supplementary irrigation is required for some of the plants over a full annual cycle. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Longevity and survival of the predator Podisus connexivus (Hemiptera: Pentatomidae were studied in three alternative preys: T1 - Bombyx mori (Lepidoptera, Bombycidae catterpilars; T2 - Musca domestica (Diptera, Muscidae larva and T3 - Tenebrio molitor (Coleoptera, Tenebrionidae larva. Longevity and survival were: 22,1±0,6 days and 54,3±5,3%; 25,2±1,3 days and 56,0±4,9% and 22,0±0,8 days and 34,6±8,6%, for treatments T1, T2 and T3, respectively. Comparing to other researches, a lower survival was found. This is probably because a F2 generation from field material, was used. Since the insect was not well adapted to the laboratory conditions this could have led to lower survival.

    Background Prospective follow-up studies of large cohorts of patients with glioblastoma (GBM) are needed to assess the effectiveness of conventional treatments in clinical practice. We report GBM survival data from the Brain Cancer Register of the Fondazione Istituto Neurologico Carlo Besta (INCB) in Milan, Italy, which collected longitudinal data for all consecutive patients with GBM from 1997 to 2010. Methods Survival data were obtained from 764 patients (aged>16 years) with histologically confirmed primary GBM who were diagnosed and treated over a 7-year period (2004–2010) with follow-up to April 2012 (cohort II). Equivalent data from 490 GBM patients diagnosed and treated over the preceding 7 years (1997–2003) with follow-up to April 2005 (cohort I) were available for comparison. Progression-free survival (PFS) was available from 361 and 219 patients actively followed up at INCB in cohorts II and I, respectively. Results Survival probabilities were 54% at 1 year, 21% at 2 years, and 11% at 3 years, respectively, in cohort II compared with 47%, 11%, and 5%, respectively, in cohort I. PFS was 22% and 12% at 1 year in cohorts II and I. Better survival and PFS in cohort II was significantly associated with introduction of the Stupp protocol into clinical practice, with adjusted hazard ratios (HRs) of 0.78 for survival and 0.73 for PFS, or a 22% relative decrease in the risk of death and a 27% relative decrease in the risk of recurrence. After recurrence, reoperation was performed in one-fifth of cohort I and in one-third of cohort II but was not effective (HR, 1.05 in cohort I and 1.02 in cohort II). Second-line chemotherapy, mainly consisting of nitrosourea-based chemotherapy, temozolomide, mitoxantrone, fotemustine, and bevacizumab, improved survival in both cohorts (HR, 0.57 in cohort I and 0.74 in cohort II). Radiosurgery was also effective (HR, 0.52 in cohort II). Conclusions We found a significant increase in overall survival, PFS, and survival after

    Survival analysis is useful in clinical research because it focuses on comparing the survival distributions and the identification of risk factors. Our aim in this study was to investigate the survival characteristics and risk factors of orthodontic mini-implants with survival analyses. One hundred forty-one orthodontic patients (treated from October 1, 2000, to November 29, 2007) were included in this survival study. A total of 260 orthodontic mini-implants that had sandblasted (large grit) and acid-etched screw parts were placed between the maxillary second premolar and the first molar. Failures of the implants were recorded as event data, whereas implants that were removed because treatment ended and those that were not removed during the study period were recorded as censored data. A nonparametric life table method was used to visualize the hazard function, and Kaplan-Meier survival curves were generated to identify the variables associated with implant failure. Prognostic variables associated with implant failure were identified with the Cox proportional hazard model. Of the 260 implants, 22 failed. The hazard function for implant failure showed that the risk is highest immediately after placement. The survival function showed that the median survival time of orthodontic mini-implants is sufficient for relatively long orthodontic treatments. The Cox proportional hazard model identified that increasing age is a decisive factor for implant survival. The decreasing pattern of the hazard function suggested gradual osseointegration of orthodontic mini-implants. When implants are placed in a young patient, special caution is needed to lessen the increased probability of failure, especially immediately after placement.

    Several prosthetic materials have been used for femoropopliteal bypass grafting in patients with peripheral vascular disease in whom a venous bypass is not possible. Expanded polytetrafluoroethylene (ePTFE) is the most commonly used, but patency results have not always equaled those achieved with vein, especially in below-knee reconstructions. This study assessed the performance of a new heparin-bonded ePTFE vascular graft that was designed to provide resistance to thrombosis and thereby decrease early graft failures and possibly prolong patency. From June 2002 to June 2003, 86 patients (62 men and 24 women; mean age, 70 years; 99 diseased limbs) were enrolled prospectively in a nonrandomized, multicenter study of the heparin-bonded ePTFE graft. Fifty-five above-knee and 44 below-knee (including 21 femorocrural) procedures were performed. Follow-up evaluations consisted of clinical examinations, ultrasonographic studies, and distal pulse assessments. Patency and limb salvage rates were assessed by using life-table analyses. All grafts were patent immediately after implantation. There were no graft infections or episodes of prolonged anastomotic bleeding. During the 1-year follow-up, 10 patients died, 15 grafts occluded, and 5 major amputations were performed. The overall primary and secondary 1-year patency rates were 82% and 97%, respectively. The limb salvage rate in patients with critical limb ischemia (n = 41) was 87%. Primary patency rates according to bypass type were 84%, 81%, and 74% for above-knee femoropopliteal, below-knee femoropopliteal, and femorocrural bypasses, respectively; the corresponding secondary patency rates were 96%, 100%, and 100%. In this study, the heparin-bonded ePTFE graft provided promising early patency and limb salvage results, with no device-related complications, in patients with occlusive vascular disease. Longer-term and randomized studies are warranted to determine whether this graft provides results superior to those achieved

    Normal tension glaucoma (NTG) is commonly treated with anti-glaucoma medications. Recently, selective laser trabeculoplasty (SLT) has been demonstrated to lower the intraocular pressure (IOP) and medication use in NTG. The purpose of this study was to investigate the efficacy of a single session of SLT for NTG at 1 year. This prospective cohort study recruited NTG patients taking anti-glaucoma medication. Potential subjects were excluded if they had had previous glaucoma surgery or laser and also if intraocular surgery or additional SLT procedures were performed after the first treatment. All subjects underwent a 1-month washout. A 30% IOP reduction was set as the target IOP. A single session of SLT was performed to 360 degrees of the trabecular meshwork. At 1-month after SLT, medication was resumed to achieve the target IOP. The IOP was measured every 3 months, and the number of medications was recorded at 3, 6, and 12 months. Only the right eye was used for statistical analysis. In 41 right eyes, the mean pre-study IOP was 14.3 ± 3.4 mmHg while on 1.5 ± 0.8 eye drops. The post-washout IOP was 16.2 ± 2.2 mmHg. A mean of 191.1 ± 26.3 SLT shots at 1.0 ± 0.07 mJ were applied. There was significant IOP reduction at all time intervals following SLT when compared to the post-washout IOP (P 1). The number of medications was significantly reduced at all time intervals following SLT when compared to the pre-study level (P 1). At 12 months, the mean IOP was 12.2 ± 2.2 mmHg while on 1.1 ± 0.9 eye drops. A single session of SLT for NTG achieved an additional 15% IOP reduction while using 27% less medication at 1 year compared to pre-study levels.

    The impact of coronary artery disease (CAD) on outcomes after transcatheter aortic valve replacement (TAVR) is understudied. Literature on the prognostic role of CAD in the survival of patients undergoing TAVR shows conflicting results. This meta-analysis aims to investigate how CAD impacts patient survival following TAVR. We completed a comprehensive literature search of Embase, MEDLINE, and the Cochrane Library, and included studies reporting outcome of TAVR based on CAD status of patients for the analysis. From the initial 1631 citations, 15 studies reporting on 8013 patients were analyzed using a random-effects model. Of the 8013 patients undergoing TAVR, with a median age of 81.3 years (79-85.1 years), 46.6% (40-55.7) were men and 3899 (48.7%) had CAD (ranging from 30.8% to 78.2% in various studies). Overall, 3121 SAPIEN/SAPIEN XT/SAPIEN 3 (39.6%) and 4763 CoreValve (60.4%) prostheses were implanted, with transfemoral access being the most frequently used approach for the implantation (76.1%). Our analysis showed no significant difference between patients with and without CAD for all-cause mortality at 30 days post TAVR, with a cumulative odds ratio of 1.07 (95% confidence interval, 0.82-1.40; P=0.62). However, there was a significant increase in all-cause mortality at 1 year in the CAD group compared with patients without CAD, with a cumulative odds ratio of 1.21 (95% confidence interval, 1.07-1.36; P=0.002). Even though coexisting CAD does not impact 30-day mortality, it does have an impact on 1-year mortality in patients undergoing TAVR. Our results highlight a need to revisit the revascularization strategies for concomitant CAD in patients with TAVR. © 2017 The Authors.

    To compare epithelial connective tissue graft vs porcine collagen matrix for sealing postextraction sockets grafted with deproteinised bovine bone. A total of 30 patients, who needed a maxillary tooth to be extracted between their premolars and required a delayed, fixed, single implant-supported restoration, had their teeth atraumatically extracted and their sockets grafted with deproteinised bovine bone. Patients were randomised according to a parallel group design into two arms: socket sealing with epithelial connective tissue graft (group A) vs porcine collagen matrix (group B). Outcome measures were: implant success and survival rate, complications, horizontal and vertical alveolar bone dimensional changes measured on Cone Beam computed tomography (CBCT) scans at three levels localised 1, 3, and 5 mm below the most coronal aspect of the bone crest (levels A, B, and C); and between the palatal and buccal wall peaks (level D); and peri-implant marginal bone level changes measured on periapical radiographs. 15 patients were randomised to group A and 15 to group B. No patients dropped out. No failed implants or complications were reported 1 year after implant placement. Five months after tooth extraction there were no statistically significant differences between the 2 groups for both horizontal and vertical alveolar bone dimensional changes. At level A the difference was 0.13 ± 0.18; 95% CI 0.04 to 0.26 mm (P = 0.34), at level B it was 0.08 ± 0.23; 95% CI -0.14 to 0.14 (P = 0.61), at level C it was 0.05 ± 0.25; 95% CI -0.01 to 0.31 mm (P = 0.55) and at level D it was 0.13 ± 0.27; 95% CI -0.02 to 0.32 mm (P = 0.67). One year after implant placement there were no statistically significant differences between the 2 groups for peri-implant marginal bone level changes (difference: 0.07 ± 0.11 mm; 95% CI -0.02 to 0.16; P = 0.41). When teeth extractions were performed atraumatically and sockets were filled with deproteinised bovine bone, sealing the socket with a

    Full Text Available It is widely accepted that a redundant independent dose calculation (RIDC must be included in any treatment planning verification procedure. Specifically, volumetric modulated arc therapy (VMAT technique implies a comprehensive quality assurance (QA program in which RIDC should be included. In this paper, the results obtained in 1 year of clinical experience are presented. Eclipse from Varian is the treatment planning system (TPS, here in use. RIDC were performed with the commercial software; Diamond ® (PTW which is capable of calculating VMAT fields. Once the plan is clinically accepted, it is exported via Digital Imaging and Communications in Medicine (DICOM to RIDC, together with the body contour, and then a point dose calculation is performed, usually at the isocenter. A total of 459 plans were evaluated. The total average deviation was -0.3 ± 1.8% (one standard deviation (1SD. For higher clearance the plans were grouped by location in: Prostate, pelvis, abdomen, chest, head and neck, brain, stereotactic radiosurgery, lung stereotactic body radiation therapy, and miscellaneous. The highest absolute deviation was -0.8 ± 1.5% corresponding to the prostate. A linear fit between doses calculated by RIDC and by TPS produced a correlation coefficient of 0.9991 and a slope of 1.0023. These results are very close to those obtained in the validation process. This agreement led us to consider this RIDC software as a valuable tool for QA in VMAT plans.

    In this cohort of individuals with and without multiple sclerosis (MS), we illustrate some of the novel approaches that smartphones provide to monitor patients with chronic neurologic disorders in their natural setting. Thirty-eight participant pairs (MS and cohabitant) aged 18-55 years participated in the study. Each participant received an Android HTC Sensation 4G smartphone containing a custom application suite of 19 tests capturing participant performance and patient-reported outcomes (PROs). Over 1 year, participants were prompted daily to complete one assigned test. A total of 22 patients with MS and 17 cohabitants completed the entire study. Among patients with MS, low scores on PROs relating to mental and visual function were associated with dropout (p color vision test were captured, highlighting the benefits of both active and passive data collection. Third, a new trait, a person-specific learning curve in neuropsychological testing, was identified using spline analysis. Finally, averaging repeated measures over the study yielded the most robust correlation matrix of the different outcome measures. We report the feasibility of, and barriers to, deploying a smartphone platform to gather useful passive and active performance data at high frequency in an unstructured manner in the field. A smartphone platform may therefore enable large-scale naturalistic studies of patients with MS or other neurologic diseases.

    Full Text Available ABSTRACT Purpose: We aimed to report and analyze topographic and refractive outcomes following corneal collagen crosslinking (CXL in patients with progressive keratoconus (KC. Methods: We performed a retrospective, analytical, and observational study of 100 eyes from 74 progressive KC patients who underwent CXL at the Eye Hospital of Paraná. Keratometric values were analyzed preoperatively as well as 3 and 12 months postoperatively. Results: For a total of 100 eyes, 68 belonged to male patients. The mean age of our study population was 19.9 ± 5.61 years. The average visual acuity and topographic parameters overall were stable after 1 year (p<0.05. After 3 months, steepest keratometry reading (K2 and maximum keratometry (Kmax were significantly decreased (p<0.05. Regarding topographic astigmatism (dK, there was no significant difference between the 3-month and 12-month follow-ups. When we made comparisons between genders following CXL, there were no significant differences related to the changes in Kmax, K2, and spectacle-corrected distance visual acuity (SCDVA. Conclusions: CXL promoted stabilization or improvement of keratometric values and visual acuity. We found that keratoconus apex stability may be achieved 3 months after the procedure. There was no significant difference in keratometric and refractive values measured between male and female patients.

    Full Text Available Objective : To evaluate and compare the retention, marginal discoloration, surface texture and anatomical form of pit and fissure sealants. Materials and Methods : Thirty children between the ages of 6 and 10 years, who were attending the school health program regularly, had participated in the study. A split-mouth design was used in which the two fissure sealants (Helioseal-F and Glass ionomer Fuji VII were randomly placed in 60 matched contralateral pairs of permanent molar teeth. Sealants were rated by a single trained and calibrated examiner using mouth mirrors and probes following the US Public Health Service criteria. The sealants were evaluated at 3 months, 6 months and 1 year intervals. Results : The data obtained for retention, marginal discoloration, surface texture and anatomical form of pit and fissure sealants were tabulated and compared statistically using the Chi-square test of significance. Conclusion : The Helioseal-F sealant was better than the Glass ionomer Fuji VII sealant with respect to retention, anatomical form and surface texture. Both the materials showed similar results with respect to marginal discoloration.

    A 1-year-old female Labrador retriever was referred with a few days history of haematic-like vulvar discharge. Physical examination, vaginal inspection and palpation did not reveal any remarkable finding. Transabdominal ultrasound showed echogenic fluid accumulation in the vagina suggesting haemato-pyocolpos. An exploratory laparotomy was performed: a well-delimited ectasic vagina was identified. Ovariohysterectomy and partial vaginectomy and vaginoplasty were performed to spay the bitch and to remove the ectasic vagina. Post-operative recovery and 12-month follow-up were uneventful. Clinical, morphological and histological findings were consistent with a congenital abnormality of the muscular layer of the vagina complicated by haemato-pyocolpos. The disorganization of the vaginal tunica muscularis may have acted as locus minoris resistentiae in the vaginal wall. The organ was dilated and atonic due to the gradual accumulation of physiological fluids complicated by an overgrowth of genital bacteria. This congenital disorder has to be taken into account as differential diagnosis of haemato-pyocolpos with vaginal discharge in young bitches. © 2015 Blackwell Verlag GmbH.

    To evaluate biocompatibility of Carbon (C) and Titanum (T) surface modified Polymethyl-methacrylate (PMMA) Intraocular Lens (IOLs) in pseudophakic rabbit model. Extracapsule Cataract Extraction (ECCE) and IOLs implantation were performed in Japanese albino rabbit eyes. The white cell concentration from the aqueous humor in the eyes was counted within 3 months post operation. The inflammatory cells in the eyes were noted and graded by slit lamp using a semiquantitive scale up to 1-year post operation. The rabbit eyes were inspected under light microscopy, where pathology of the eyes was caracterized. The white cell concentration in the aqueous humor was significantly attenuated in C and T IOL-implanted eyes compared with PMMA IOL-implanted eyes 1 week post operation. The exudate levels in the anterior ocular chamber and the posterior synechias were significant lower in T IOL-implanted eyes than in PMMA IOL-implanted eyes 1 week and 2 weeks after surgery. The exudate levels in the anterior chambers and the posterior synechias were not significantly different in C IOL-implanted versus PMMA IOL-implanted eyes. This in vivo study provides evidence of effectiveness of Carbon and Titanium IOLs in improving the biocompatibility of PMMA IOLs.

    Kidney transplantation from a living donor nephrectomy (LDN) is the best treatment for end-stage renal disease, but decrease in donor renal function is often revealed. The aim of this study was to evaluate the association between preoperative factors and postoperative estimated glomerular filtration rate (eGFR) and test a predictive model to estimate postoperative eGFR, 1 year after LDN. We reviewed 226 records of consecutive patients who underwent laparoscopic live donor nephrectomy between 2006 and 2014 in a single tertiary center. Of these, complete data on 202 patients were analyzed. A training (2/3 of the whole population) and a validation set (1/3) were randomized. A multivariate regression model was used to identify predictors and a formula to estimate of 1-year postoperative eGFR in the training set, using the CKD-EPI formula. Then, the formula was subjected to internal validation using the validation set using receiver operating characteristic (ROC) curves. Two hundred and two LLDN were evaluated with a mean preoperative eGFR of 94.1 ± 15.5 ml/min/1.73 m2 and postoperative eGFR of 64.6 ± 14.5 ml/min/1.73 m2 (p predictive model of postoperative eGFR developed could be an accurate tool to improve the selection of LDN candidates.

    To investigate whether or not bariatric surgery weight outcomes vary by ethnicity in a large, nationally representative sample of adolescents. The Bariatric Outcomes Longitudinal Database was used for analysis and contains data on surgeries performed on adolescents from 2004 to 2010 from 423 surgeons at 360 facilities across the United States Adolescents (n = 827) between 11 and 19 years old who underwent either gastric bypass or adjustable gastric banding surgery were included in the analysis. Outcome measures included changes in anthropometric measurements [weight (kg) and body mass index] from baseline to 3 (n = 739), 6 (n = 512), and 12 (n = 247) mo after surgery. A year after patients underwent either gastric bypass (51%) or adjustable gastric banding (49%) surgery, mean estimated weight loss for all ethnic groups differed by a maximum of only 1.5 kg, being 34.3 kg (95%CI: 30.0-38.5 kg) for Hispanics, 33.8 kg (95%CI: 27.3-40.3 kg) for non-Hispanic blacks, and 32.8 kg (95%CI: 30.9-34.7 kg) for non-Hispanic whites. No overall pairwise group comparisons were significant, indicating that no ethnic group had better weight loss outcomes than did another. Bariatric surgery substantially reduces the weight of severely obese adolescents at 1 year post-procedure with little variation by ethnicity and/or gender. These results suggest that bariatric surgery is a safe and reasonable treatment for all severely obese adolescents with the appropriate indications.

    To understand the effect of unintentional injuries (e.g., drug overdose), suicide, and homicide on pregnancy-associated death (death during or within 1 year of pregnancy). We analyzed all cases of pregnancy-associated death among Philadelphia, Pennsylvania, residents from 2010 to 2014, examining cause of death, contributing factors, and history of health care use. Approximately half (49%; 42 of 85) of pregnancy-associated deaths were from unintentional injuries (n = 31), homicide (n = 8), or suicide (n = 3); drug overdose was the leading cause (n = 18). Substance use was noted during or around events leading to death in 46% (31 of 67) of nonoverdose deaths. A history of serious mental illness was noted in 39% (32 of 82) of nonsuicide deaths. History of intimate partner violence (IPV) was documented in 19% (15 of 77) of nonhomicide deaths. Regardless of cause of death, approximately half of all decedents had an unscheduled hospital visit documented within a month of death. Unintentional injury, homicide, and suicide contribute to many deaths among pregnant and recently pregnant women. Interventions focused on substance use, mental health, and IPV may reduce pregnancy-associated and pregnancy-related deaths.

    Several studies showed the close relationship between Rheumatoid Arthritis (RA) and cerebro-cardiovascular events (CVEs) and subclinical atherosclerosis. In this study, we investigated the occurrence of CVEs and subclinical atherosclerosis during the course of RA and we evaluated the possible role of both traditional cardiovascular (CV) and disease related risk factors to predict the occurrence of new CVEs and the onset of subclinical atherosclerosis. We designed a single centre, bias-adjusted, prospective, observational study to investigate, in a homogeneous subset of RA patients, the occurrence of new onset of CVEs and subclinical atherosclerosis. Statistical analyses were performed to evaluate the role of traditional CV and disease-related risk factors to predict the occurrence of new CVEs and subclinical atherosclerosis. We enrolled 347 RA patients prospectively followed for 12 months. An increased percentage of patients experienced CVEs, developed subclinical atherosclerosis and was affected by systemic arterial hypertension (SAH), type 2 diabetes mellitus and metabolic syndrome (MS), at the end of follow up. Our analysis showed that the insurgence of both SAH and MS, during the follow up, the older age, the CVE familiarity and the lack of clinical response, were associated with a significantly increased risk to experience CVEs and to develop subclinical atherosclerosis. Our study quantifies the increased expected risk for CVEs in a cohort of RA patients prospectively followed for 1 year. The occurrence of both new CVEs and subclinical atherosclerosis in RA patients may be explained by inflammatory burden as well as traditional CV risk factors.

    Research findings are inconsistent about improvement of specific cardio-metabolic variables after lifestyle intervention in obese children. The aim of this trial was to evaluate the effect of a 1-year intervention, based on normocaloric diet and physical activity, on body mass index (BMI), blood lipid profile, glucose metabolism and metabolic syndrome. Eighty-five obese children aged ≥6 years were analyzed. The BMI z-score was calculated. Fasting blood samples were analyzed for lipids, insulin and glucose. The homeostatic model assessment of insulin resistance (HOMA-IR) was calculated and insulin resistance was defined as HOMA-IR >3.16. HOMA-β%, quantitative insulin sensitivity check index and triglyceride glucose index were calculated. The metabolic syndrome was defined in accordance with the International Diabetes Federation criteria. At the end of intervention children showed a reduction (mean (95% CI)) in BMI z-score (-0.58 (-0.66; -0.50)), triglycerides (-0.35 (-0.45; -0.25) mmol/L) and triglyceride glucose index (-0.29 (-0.37; -0.21)), and an increase in HDL cholesterol (0.06 (0.01; 0.11) mmol/L). Prevalence of insulin resistance declined from 51.8% to 36.5% and prevalence of metabolic syndrome from 17.1% to 4.9%. Nutritional-behavioral interventions can improve the blood lipid profile and insulin sensitivity in obese children, and possibly provide benefits in terms of metabolic syndrome.

    Full Text Available Arachnoid cysts are defined as an accumulation of fluid within the arachnoid membrane. Feline intracranial arachnoid cysts are seldom reported, with only three cases in the veterinary literature. A 1-year-old male neutered European cat with a 24 h history of seizures was presented to the small animal neurology department at Vetagro Sup, Lyon. Magnetic resonance imaging (MRI revealed a large intracranial arachnoid cyst ventral to the brain in the left temporal area. Cystoperitoneal shunt placement resulted in complete resolution of the cyst without recurrence (follow-up MRIs 3 weeks and 21 months after surgery. Anticonvulsant treatment (phenobarbital 2.5 mg/kg q12h was initiated at presentation and gradually stopped after 17 months. Seizures recurred 4 months after ending treatment, and seizure therapy was therefore restarted at the initial dose. We report a case of an intracranial arachnoid cyst in an unusual location not previously described. A cystoperitoneal shunt resolved the cyst without complications. Maintenance anticonvulsant treatment was required to control symptomatic epilepsy.

    Renal denervation (RDN) reduces muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in resistant hypertension. Although a persistent BP-lowering effect has been demonstrated, the long-term effect on MSNA remains elusive. We investigated whether RDN influences MSNA over time. Office BP and MSNA were obtained at baseline, 3, 6, and 12 months after RDN in 35 patients with resistant hypertension. Office BP averaged 166±22/88±19 mm Hg, despite the use of an average of 4.8±2.1 antihypertensive drugs. Baseline MSNA was 51±11 bursts/min ≈2- to 3-fold higher than the level observed in healthy controls. Mean office systolic and diastolic BP significantly decreased by -12.6±18.3/-6.5±9.2, -16.1±25.6/-8.6±12.9, and -21.2±29.1/-11.1±12.9 mm Hg (Phypertension and high baseline MSNA. These observations are compatible with the hypothesis of a substantial contribution of afferent renal nerve signaling to increased BP in resistant hypertension and argue against a relevant reinnervation at 1 year after procedure. © 2014 American Heart Association, Inc.

    We assessed changes in smoking prevalence and other measures associated with the July 2008 New York Office of Alcoholism and Substance Abuse Services tobacco policy, which required that all publicly funded addiction treatment programs implement smoke-free grounds, have "no evidence" of smoking among staff, and make tobacco dependence treatment available for all clients. In a random sample of 10 programs, staff and clients were surveyed before the policy and 1 year later. Measures included tobacco-related knowledge, attitudes, and practices used by counselors and received by clients. Client smoking decreased from 69.4% to 62.8% (P = .044). However, response to the policy differed by program type. Outpatient programs showed no significant changes on any of the staff and client survey measures. In methadone programs, staff use of tobacco-related practices increased (P smoking after policy implementation (odds ratio = 4.7; 95% confidence interval = 1.53, 14.19), but they reported less favorable attitudes toward tobacco treatment (P policy may offer a model that addiction treatment systems can use to address smoking in a population where it has been prevalent and intractable. Additional intervention or policy supports may be needed in residential programs, which face greater challenges to implementing tobacco-free grounds.

    Static two-point discrimination, pressure, and vibratory threshold values were measured at standard coordinates in the area corresponding to the infraorbital nerve distribution in 59 adolescents 1 year after undergoing LeFort I osteotomy. The patients were divided into three groups: those born with unilateral cleft lip and palate (n = 30; mean age, 18 years; SD = 2); those with bilateral cleft lip and palate (n = 12; mean age, 19 years; SD = 3); and those without a cleft (n = 17; mean age, 19 years; SD = 3). One year after the osteotomy, none of the patients complained of altered sensibility in the maxillary vestibular mucosa, gingiva, or upper lip and cheek regions. No significant differences were found between the mean postoperative sensibility values of patients with and without clefts, indicating that the presence of clefting did not affect sensory recovery. Mean postoperative static two-point discrimination values were higher than preoperative values in all areas tested and in all patient groups. These results suggest that the sensory recovery, although incomplete, was strong enough to mask any subjective feelings of changes in sensory function.

    Despite recognition of the need for parenting interventions to prevent childhood behavioral problems, few community programs have been evaluated. This report describes the randomized controlled evaluation of a four-session psychoeducational group for parents of preschoolers with behavior problems, delivered in community agencies. In 1998, 222 primary caregivers, recruited through community ads, filled out questionnaires on parenting practices and child behavior. Parents were randomly assigned to immediate intervention or a wait-list control. The intervention comprised three weekly group sessions and a 1-month booster, the focus being to support effective discipline (using the video 1-2-3 Magic) and to reduce parent-child conflict. Using an intent-to-treat analysis, repeated-measures analyses of variance indicated that the parents who received the intervention reported significantly greater improvement in parenting practices and a significantly greater reduction in child problem behavior than the control group. The gains in positive parenting behaviors were maintained at 1-year follow-up in a subset of the experimental group. This brief intervention program may be a useful first intervention for parents of young children with behavior problems, as it seems both acceptable and reasonably effective.

    We examined 12-month hormonal contraceptive continuation and pregnancy rates by abortion history. Women who wanted to avoid pregnancy for at least 1 year were recruited at four San Francisco Bay area family planning clinics on regular service days and on abortion care days. Participants completed baseline and follow-up questionnaires. Multivariable Cox models assessed the factors associated with method discontinuation and pregnancy. Women who were enrolled into the study on the day of their abortion were 20% more likely to discontinue their contraceptive method than women who never had an abortion [adjusted hazard ratio (AHR)=1.21, 95% confidence interval (CI)=1.03-1.42]. Women who had a recent abortion or previous abortion were 60% more likely to have a pregnancy during follow-up than women who never had an abortion (AHR=1.63, 95% CI =1.21-2.20, and AHR=1.66, 95% CI=1.18-2.33, respectively). The experience of having an unintended pregnancy and abortion does not lead to behavioral changes that protect against another unintended pregnancy. Copyright © 2012 Elsevier Inc.

    Full Text Available The objective of this study was to evaluate the effectiveness of a therapeutic sealant to arrest non-cavitated proximal carious lesion progression. The study population comprised 44 adolescents who had bitewing radiographs taken for caries diagnosis. Non-cavitated lesions extending up to half of dentin thickness were included in the sample. In the experimental group (n = 33, the proximal caries-lesion surfaces were sealed with an adhesive (OptiBond Solo, Kerr after tooth separation. The control group (n = 11 received no treatment, except for oral hygiene instructions including use of dental floss. Follow-up radiographs were taken after one year and were analyzed in comparison with baseline radiographs. In a blind study setting, visual readings were performed by two examiners, blinded to whether the examined radiograph was baseline or follow-up, and whether it concerned a test or control lesion. The efficacy of sealing treatment was evaluated by the McNemar test (0.05. About 22% of the sealed lesions showed reduction, 61% showed no change and 16% showed progression. For the control lesions, the corresponding values were 27%, 36% and 36% respectively. The number of lesions that showed reduction and no changes were merged and therefore 83.3% of the sealed lesions and 63.6% of the control lesions were considered clinically successful. No statistical significance was detected (p > 0.05. In the course of 1 year, sealing proximal caries lesions was not shown to be superior to lesion monitoring.

    To compare the clinical outcome of single implants which underwent immediate nonocclusal loading with implants subjected to early non-occlusal loading at 3 weeks, and implants conventionally loaded at 4 months. One hundred and five patients in five private practices requiring a single implant-supported crown were randomised to immediate loading (35 patients), early loading (35 patients) and conventional loading (35 patients) groups. To be immediately or early loaded, implants had to be inserted with a torque superior to 45 Ncm. Immediately and early loaded implants received non-occluding temporary crows, whereas conventionally loaded implants were directly restored with definitive crowns. Temporary crowns were replaced by definitive ones after 4 months. Outcome measures were crown and implant failures, complications and peri-implant marginal bone level changes recorded by a blinded assessor. Two patients dropped out from the immediate loading group up to 1-year post-loading. Two implants failed, one in the immediately loaded and one in the early loaded group (P=0.601). One immediately loaded implant and two early loaded implants were affected by one complication each (P=0.162). Mean peri-implant marginal bone loss after 1 year was -0.120±0.230 mm (95% CI -0.35, 0.10) for immediate, -0.390±0.840 mm (95% CI -1.23, 0.45) for early and -0.201±0.306 mm (95% CI -0.51; 0.11) for conventionally loaded implants. There were no statistically significant differences for any of the outcome measures between the three loading strategies up to 1-year post-loading. No major clinical differences were observed with regard to implant survival, complications and marginal bone level changes when loading single implants immediately, early or conventionally.

    Pretreatment C-reactive protein (CRP) has been shown to be an independent prognostic factor for metastatic renal cell carcinoma (mRCC) treated with tyrosine kinase inhibitors (TKIs). We further evaluated the early response of CRP after the initiation of TKIs. A total of 103 patients (80 men and 23 women) were treated with TKIs for mRCC from 2008-2013. Patients were divided into three groups according to their early CRP kinetics-patients whose baseline CRP levels were 20% at 4 weeks after the initiation of TKIs (early CRP responder), and the remaining patients (non-early CRP responder). The endpoints were progression-free survival (PFS) and overall survival (OS). The median follow-up period was 21 (interquartile range 10-34) months. The numbers of patients classified as non-elevated, early CRP responder, and non-early CRP responder were 62, 19, and 22, respectively. The 1-year PFS rates of patients in the non-elevated, early CRP responder, and non-early CRP responder groups were 50, 23, and 9.7%, respectively (p < 0.001). The 1-year OS rates of patients in these three groups were 79, 62, and 36%, respectively (p < 0.001). In multivariate analysis, the early CRP kinetics assessment was a significant independent factor for PFS and OS. Early CRP response at 4 weeks is predictive of survival for patients with mRCC treated with TKI.

    Racial and ethnic disparities in cardiovascular disease are well established; however, there is limited information about survival differences following veno-venous extracorporeal membrane oxygenation (VV-ECMO) in contemporary adult populations. The purpose of this study was to assess survival at discharge, 30 days, and at 1 year following institution of VV-ECMO in an ethnically diverse population, and to examine potential risk factors for mortality. This was a single-center study of 41 patients (49% female, 27% minorities, 7% > 65 years) who received VV-ECMO between the years 2004 and 2013 at an academic medical center. Kaplan-Meier estimates were calculated to assess survival up to 1 year, and cox proportional hazard models were used to evaluate the association between risk factors, mortality, and confounders. Overall, 76% (n = 31) of VV-ECMO patients survived to discharge and 30 days and 71% (n = 29) survived to 1 year. Whites (n = 30) had a higher survival at 1 year compared to minorities (n = 11) (83% vs. 36%, respectively, p = .01). Minorities had a significantly increased risk of mortality at 30 days (hazard ratio [HR] = 5.07, 95% confidence interval [CI] = 1.42-18.09) and at 1 year (HR = 5.19, 95% CI = 1.63-16.55). Race/ethnicity remained a significant independent predictor of survival at 30 days except when history of shock or lung transplantation was included in adjusted regression models. VV-ECMO was associated with an excellent overall survival up to 1 year. Racial/ethnic minorities had a 5-fold increased risk for 30-day mortality, which was largely explained by a lower likelihood of lung transplantation and increased risk of shock.

    Cardiogenic shock (CS) is the leading cause of death for patients hospitalized with acute myocardial infarction (AMI). To assess the effect of early revascularization (ERV) on 1-year survival for patients with AMI complicated by CS. The SHOCK (Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock) Trial, an unblinded, randomized controlled trial from April 1993 through November 1998. Thirty-six referral centers with angioplasty and cardiac surgery facilities. Three hundred two patients with AMI and CS due to predominant left ventricular failure who met specified clinical and hemodynamic criteria. Patients were randomly assigned to an initial medical stabilization (IMS; n = 150) group, which included thrombolysis (63% of patients), intra-aortic balloon counterpulsation (86%), and subsequent revascularization (25%), or to an ERV group (n = 152), which mandated revascularization within 6 hours of randomization and included angioplasty (55%) and coronary artery bypass graft surgery (38%). All-cause mortality and functional status at 1 year, compared between the ERV and IMS groups. One-year survival was 46.7% for patients in the ERV group compared with 33.6% in the IMS group (absolute difference in survival, 13.2%; 95% confidence interval [CI], 2.2%-24.1%; P/= 75 years) interacted significantly (P<.03) with treatment in that treatment benefit was apparent only for patients younger than 75 years (51.6% survival in ERV group vs 33.3% in IMS group). Eighty-three percent of 1-year survivors (85% of ERV group and 80% of IMS group) were in New York Heart Association class I or II. For patients with AMI complicated by CS, ERV resulted in improved 1-year survival. We recommend rapid transfer of patients with AMI complicated by CS, particularly those younger than 75 years, to medical centers capable of providing early angiography and revascularization procedures.

    Maintenance dialysis is associated with reduced survival when compared with the general population. In Libya, information about outcomes on dialysis is scarce. This study, therefore, aimed to provide the first comprehensive analysis of survival in Libyan dialysis patients. This prospective multicenter study included all patients in Libya who had been receiving dialysis for >90 days in June 2009. Sociodemographic and clinical data were collected upon enrollment and survival status after 1 year was determined. Two thousand two hundred seventy-three patients in 38 dialysis centers were followed up for 1 year. The majority were receiving hemodialysis (98.8%). Sixty-seven patients were censored due to renal transplantation, and 46 patients were lost to follow-up. Thus, 2159 patients were followed up for 1 year. Four hundred fifty-eight deaths occurred, (crude annual mortality rate of 21.2%). Of these, 31% were due to ischemic heart disease, 16% cerebrovascular accidents, and 16% due to infection. Annual mortality rate was 0% to 70% in different dialysis centers. Best survival was in age group 25 to 34 years. Binary logistic regression analysis identified age at onset of dialysis, physical dependency, diabetes, and predialysis urea as independent determinants of increased mortality. Patients receiving dialysis in Libya have a crude 1-year mortality rate similar to most developed countries, but the mean age of the dialysis population is much lower, and this outcome is thus relatively poor. As in most countries, cardiovascular disease and infection were the most common causes of death. Variation in mortality rates between different centers suggests that survival could be improved by promoting standardization of best practice. © 2012 The Authors.

    Diabetes mellitus (DM) is associated with adverse outcomes after surgical aortic valve replacement. However, there are conflicting data on the impact of DM on outcomes of transcatheter aortic valve replacement (TAVR). DM is associated with poor outcomes after different cardiac procedures. Therefore, DM can also be associated with poor outcomes after TAVR. We searched PubMed and Cochrane Central Register of Controlled Trials for studies that evaluated outcomes after TAVR and stratified at least 1 of the studied endpoints by DM status. The primary endpoint was all-cause mortality at 1 year. Secondary endpoints were early (up to 30 days) mortality, acute kidney injury (AKI), cerebrovascular accident (CVA), major bleeding, and major vascular complications. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using random effects models. We included 64 studies with a total of 38 686 patients. DM was associated with significantly higher 1-year mortality (OR: 1.14, 95% CI: 1.04-1.26, P = 0.008) and periprocedural AKI (OR: 1.28, 95% CI: 1.08-1.52, P = 0.004). On the other hand, there were no significant differences between diabetics and nondiabetics in early mortality, CVAs, major bleeding, or major vascular complications. DM is associated with increased 1-year mortality and periprocedural AKI in patients undergoing TAVR. The results of this study suggest that DM is a predictor of adverse outcomes in patients undergoing TAVR. © 2017 Wiley Periodicals, Inc.

    Patients suffering from neurogenic intermittent claudication secondary to lumbar spinal stenosis have historically been limited to a choice between a decompressive laminectomy with or without fusion or a regimen of non-operative therapies. The X STOP Interspinous Process Distraction System (St. Francis Medical Technologies, Concord, Calif.), a new interspinous implant for patients whose symptoms are exacerbated in extension and relieved in flexion, has been available in Europe since June 2002. This study reports the results from a prospective, randomized trial of the X STOP conducted at nine centers in the U.S. Two hundred patients were enrolled in the study and 191 were treated; 100 received the X STOP and 91 received non-operative therapy (NON OP) as a control. The Zurich Claudication Questionnaire (ZCQ) was the primary outcomes measurement. Validated for lumbar spinal stenosis patients, the ZCQ measures physical function, symptom severity, and patient satisfaction. Patients completed the ZCQ upon enrollment and at follow-up periods of 6 weeks, 6 months, and 1 year. Using the ZCQ criteria, at 6 weeks the success rate was 52% for X STOP patients and 10% for NON OP patients. At 6 months, the success rates were 52 and 9%, respectively, and at 1 year, 59 and 12%. The results of this prospective study indicate that the X STOP offers a significant improvement over non-operative therapies at 1 year with a success rate comparable to published reports for decompressive laminectomy, but with considerably lower morbidity.

  7. SURVIVAL ANALYSIS AND LENGTH-BIASED SAMPLING

    Full Text Available When survival data are colleted as part of a prevalent cohort study, the recruited cases have already experienced their initiating event. These prevalent cases are then followed for a fixed period of time at the end of which the subjects will either have failed or have been censored. When interests lies in estimating the survival distribution, from onset, of subjects with the disease, one must take into account that the survival times of the cases in a prevalent cohort study are left truncated. When it is possible to assume that there has not been any epidemic of the disease over the past period of time that covers the onset times of the subjects, one may assume that the underlying incidence process that generates the initiating event times is a stationary Poisson process. Under such assumption, the survival times of the recruited subjects are called “lengthbiased”. I discuss the challenges one is faced with in analyzing these type of data. To address the theoretical aspects of the work, I present asymptotic results for the NPMLE of the length-biased as well as the unbiased survival distribution. I also discuss estimating the unbiased survival function using only the follow-up time. This addresses the case that the onset times are either unknown or known with uncertainty. Some of our most recent work and open questions will be presented. These include some aspects of analysis of covariates, strong approximation, functional LIL and density estimation under length-biased sampling with right censoring. The results will be illustrated with survival data from patients with dementia, collected as part of the Canadian Study of Health and Aging (CSHA.

    The 1-year dog toxicity study is no longer required by certain pesticide regulatory jurisdictions, including the United States and the European Union. Health Canada's Pest Management Regulatory Agency (PMRA) examined its current requirement for this study to determine if it could be refined or eliminated. A retrospective analysis was conducted to examine the impact of the 1-year dog study on human health risk assessment. The Acceptable Daily Intake (ADI), a measure of the amount of a pesticide in food that can be ingested on a daily basis over a lifetime without an appreciable health risk, was the metric for this analysis. For 143 pesticides evaluated by the PMRA between 2008 and 2015, the supporting toxicology databases were examined to determine if other toxicology studies were protective of the findings in the 1-year dog study. When this criterion was not met, further investigation was undertaken to determine the potential impact of not having the 1-year dog study. For most of the pesticides, effect levels in the 1-year dog study were not substantially different from those in other toxicology studies, when considering factors such as dose-spacing and known experimental variability. The results of this analysis suggest that absence of the 1-year dog study would have minimal impact on the assessment of human health risk. Therefore, Health Canada's PMRA has removed the routine requirement for the 1-year dog study from its pesticide data requirements.

    To describe the effects of activity level and energy intake over time on the body weight of patients with Alzheimer's disease compared with cognitively normal subjects. Repeated measures, case-control design with measurements taken at quarterly intervals for 12 months. Subjects were grouped by gender and activity level (sedentary or active) within cognitive status. The Alzheimer's disease Special Care Unit, The Clinical Research Center at University of California, San Diego, and the Fred Kasch Exercise Physiology Laboratories at San Diego State University. Seventeen institutionalized subjects with Alzheimer's disease and 23 community-dwelling control subjects successfully completed the 1-year study. Before admission to the nursing home, the patients with Alzheimer's disease had a formal assessment for dementia, which showed that they met the criteria of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association work group for probable or possible Alzheimer's disease. Control subjects were screened using the Information-Memory-Concentration Mental Status Test and were found to have no cognitive disabilities. Baseline and quarterly measurements included height, weight, bioimpedance for body composition, and activity by accelerometer counts. Dietary intake of energy and protein was determined at baseline and at 6 and 12 months. Patients with Alzheimer's disease had a significantly higher energy intake than patients in the control group. Both women and men with Alzheimer's disease maintained their weight. Women with Alzheimer's disease had higher percentage of fat-free mass than the control group, but there were no differences in body composition between the groups of men. Subjects with Alzheimer's disease can maintain their weight if they are given a diet with adequate energy (35 kcal/kg of body weight).

    Full Text Available Research findings are inconsistent about improvement of specific cardio-metabolic variables after lifestyle intervention in obese children. The aim of this trial was to evaluate the effect of a 1-year intervention, based on normocaloric diet and physical activity, on body mass index (BMI, blood lipid profile, glucose metabolism and metabolic syndrome. Eighty-five obese children aged ≥6 years were analyzed. The BMI z-score was calculated. Fasting blood samples were analyzed for lipids, insulin and glucose. The homeostatic model assessment of insulin resistance (HOMA-IR was calculated and insulin resistance was defined as HOMA-IR >3.16. HOMA-β%, quantitative insulin sensitivity check index and triglyceride glucose index were calculated. The metabolic syndrome was defined in accordance with the International Diabetes Federation criteria. At the end of intervention children showed a reduction (mean (95% CI in BMI z-score (−0.58 (−0.66; −0.50, triglycerides (−0.35 (−0.45; −0.25 mmol/L and triglyceride glucose index (−0.29 (−0.37; −0.21, and an increase in HDL cholesterol (0.06 (0.01; 0.11 mmol/L. Prevalence of insulin resistance declined from 51.8% to 36.5% and prevalence of metabolic syndrome from 17.1% to 4.9%. Nutritional-behavioral interventions can improve the blood lipid profile and insulin sensitivity in obese children, and possibly provide benefits in terms of metabolic syndrome.

    Primary sclerosing cholangitis (PSC) is a slowly progressive liver disease. Reliable biomarkers to predict outcome are urgently needed to serve as surrogate endpoints and/or stratifiers in clinical trials. Reduction in serum alkaline phosphatase (ALP) has been proposed as prognostic surrogate marker in PSC. The aim of this study was to asses if ALP at diagnosis (T0), 1 year later (T1), and percentage change between both time points hold prognostic value, and to determine the optimal threshold. We retrospectively collected ALP levels at T0 and T1 for patients included in a large PSC cohort. The association of ALP at T0, T1, and percentage change with the combined endpoint (PSC-related death, liver transplantation) was analysed. Predictive value was determined using C-statistics. A total of 366 patients were included, of whom 66 (18%) reached an endpoint: 26 (7%) PSC-related death, 40 (11%) liver transplantation. At T0 and T1, 84% used ursodeoxycholic acid. A positive association was observed between level of ALP at T0 and T1 and the hazard of reaching an endpoint, up to values around 2.5 times upper limit of normal (xULN). A larger decrease in ALP between T0 and T1 decreased the event rate. A range of thresholds (0.5-3×ULN) with about similar C-statistics was found. In this cohort, the optimal threshold was 1.3×ULN at T1. ALP can be used to discriminate between PSC patients with a good and a poor prognosis. These findings indicate that ALP can serve as stratifier, and potentially as surrogate endpoint for clinical trials in PSC. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To explore sexual disability in injured workers undergoing rehabilitation. Specifically, we investigated (1) factors associated with high ratings of sexual disability, (2) factors associated with noncompletion of the sexual disability questionnaire, and (3) the association between sexual disability and future recovery. Historical cohort study with 1-year follow-up. Workers' compensation rehabilitation facility. Workers' compensation claimants (N=1078) undergoing return-to-work assessment. Ratings of sexual disability were measured using the Sexual Behavior item of the Pain Disability Index. Other demographic, clinical, and occupational factors also were collected. Not applicable. Outcomes included administrative indicators of timely and sustained recovery and return to work. Of subjects included in analysis, 18.5% did not complete the Sexual Behavior item. Claimants were less likely to complete if they were women, older, and single; had lower salaries, injury diagnoses other than sprain/strain, and fewer health visits before assessment; and reported lower recovery expectations. Higher levels of sexual disability were associated with higher levels of overall pain and disability, as well as being in a married/common law relationship. After adjusting for injury duration, the Sexual Behavior item was not associated significantly with any recovery measure or claims outcome. A response bias exists in Canadian injured workers asked to complete a sexual disability rating. In those completing the questionnaire, higher sexual disability was associated most closely with higher pain severity and higher disability. Perceptions of sexual disability did not contribute to predicting recovery, which supports replacement of this item for use within this and related contexts.

    Full Text Available Several studies showed the close relationship between Rheumatoid Arthritis (RA and cerebro-cardiovascular events (CVEs and subclinical atherosclerosis. In this study, we investigated the occurrence of CVEs and subclinical atherosclerosis during the course of RA and we evaluated the possible role of both traditional cardiovascular (CV and disease related risk factors to predict the occurrence of new CVEs and the onset of subclinical atherosclerosis.We designed a single centre, bias-adjusted, prospective, observational study to investigate, in a homogeneous subset of RA patients, the occurrence of new onset of CVEs and subclinical atherosclerosis. Statistical analyses were performed to evaluate the role of traditional CV and disease-related risk factors to predict the occurrence of new CVEs and subclinical atherosclerosis.We enrolled 347 RA patients prospectively followed for 12 months. An increased percentage of patients experienced CVEs, developed subclinical atherosclerosis and was affected by systemic arterial hypertension (SAH, type 2 diabetes mellitus and metabolic syndrome (MS, at the end of follow up. Our analysis showed that the insurgence of both SAH and MS, during the follow up, the older age, the CVE familiarity and the lack of clinical response, were associated with a significantly increased risk to experience CVEs and to develop subclinical atherosclerosis.Our study quantifies the increased expected risk for CVEs in a cohort of RA patients prospectively followed for 1 year. The occurrence of both new CVEs and subclinical atherosclerosis in RA patients may be explained by inflammatory burden as well as traditional CV risk factors.

    Sexual activity often begins in early adolescence, and adolescents with mental health symptoms are at greater risk for sexual activity and other health risks. This study aimed to evaluate a developmentally targeted intervention designed to enhance early adolescents' emotion regulation competencies as a strategy for reducing health risk behaviors, including sexual initiation. Adolescents 12 to 14 years old (N = 420; 53% male) with mental health symptoms participated in either an emotion regulation (ER) or health promotion (HP) intervention consisting of 12 after-school sessions. Participants completed questionnaires on laptop computers at baseline, 2-, 6-, and 12-month follow-ups. Time to event analyses were used to compare intervention conditions on rate of initiation to vaginal sex. Results showed that participants in the ER condition were less likely to transition into vaginal sexual activity by 1-year follow-up than were those in the HP condition (adjusted hazard ratio = 0.58, 95% confidence interval [0.36, 0.94], p = .01). However, those who were sexually active did not report differences in sexual risk behaviors (e.g., condomless sex). Participants in the ER condition were significantly less likely to report violence behaviors and showed improvement on a behavioral measure of emotion identification; however, they did not differ from HP participants on self-reports of emotional competence. Emotion regulation strategies can be used to delay sexual initiation among early adolescents with mental health symptoms and may have an important role in health education.

    Discontinuation of benzodiazepine (BZD) treatment for insomnia can be a difficult task. Cognitive-behavior therapy (CBT) for insomnia, combined with a supervised medication taper, can facilitate withdrawal but there is limited evidence on long-term outcome after discontinuation. The objective of this study was to examine medication-free survival time and predictors of relapse (i.e., resumed BZD hypnotics) over a 2-year period in 47 older adults (mean age 62.1 years) with persistent insomnia and prolonged BZD use (average duration of 18.9 years), who had successfully discontinued BZD following CBT for insomnia, a supervised medication taper program, or a combined approach. The Kaplan-Meier product-limit method was used to estimate survival time, defined as time between end-of-treatment and relapse or end of follow-up. By the end of the 24-month follow-up, 42.6% of the samples had resumed BZD use. Participants in the Combined (33.3%) and Taper (30.8%) groups relapsed significantly less than their counterparts from the CBT group (69.2%). Survival rates at 3 months were 61.5% (CBT), 100% (Taper), and 80.9% (Combined). At 12 months, they were 38.5%, 83.3%, and 70.8%, respectively; and, at 24 months, they were 28.9%, 64.8% and 64.9%, respectively. Mean survival time was significantly longer for both the Taper (18.6 months, SE = 2.1) and Combined groups (12.6 months, SE = 1.4), relative to the CBT group (8.5 months, SE = 1.8). Significant predictors of relapse included treatment condition, end of treatment insomnia severity, and psychological distress. In conclusion, there is a substantial relapse rate following BZD discontinuation among prolonged users. CBT booster sessions might enhance compliance with CBT and prove useful in preventing relapse.

    Full Text Available To assess the effect of renal failure on the survival of black African patients with cirrhosis, we studied 132 (82 males, 50 females cirrhotic black African patients with mean age of 47.5 ±14.4 years and mean follow-up period of 373 ± 194 days. The edema and ascitis were the main reasons for admission to hospital. Renal failure was present in 30 (22.7% patients, and it was positively correlated to the severity of the stage of the liver disease, and associated with severe hyponatremia. Survival at 1 year was 60.1% and 37.6% in the absence or presence of renal failure, respectively (p< 0.001. The stage of the liver disease was significantly inversely corre-lated with survival, which was further diminished in the presence of renal failure:23.7% versus 12.5% for Child-Pugh-Turcote (CPT A-B in the absence or presence of renal failure, respectively (p= 0.67, 30.2% versus 81.8% for CPT C in the absence or the presence of renal failure respectively (p< 0.001. Hyponatremia has also appeared detrimental to survival, since mortality was 38.4% versus 81.8% in the absence or the presence of hyponatremia respectively (p< 0.001. By multivariate analysis, renal failure, CPT stage C, and hyponatremia independently significantly correlated to mortality in patients with cirrhosis. We conclude that renal failure is frequently associated with decompensated cirrhosis. The presence of renal failure in this setting often results in high mortality. Renal failure that occurs in the setting of a severe liver disease and hyponatremia may be part of hepatorenal syndrome.

    Objective In Brazil, universal provision of antiretroviral therapy (ART) has been guaranteed free of charge to eligible HIV-positive patients since December 1996. We sought to quantify the survival benefits of ART attributable to this programme. Methods We used a previously published microsimulation model of HIV disease and treatment (CEPAC-International) and data from Brazil to estimate life expectancy increase for HIV-positive patients initiating ART in Brazil. We divided the period of 1997 to 2014 into six eras reflecting increased drug regimen efficacy, regimen availability and era-specific mean CD4 count at ART initiation. Patients were simulated first without ART and then with ART. The 2014-censored and lifetime survival benefits attributable to ART in each era were calculated as the product of the number of patients initiating ART in a given era and the increase in life expectancy attributable to ART in that era. Results In total, we estimated that 598,741 individuals initiated ART. Projected life expectancy increased from 2.7, 3.3, 4.1, 4.9, 5.5 and 7.1 years without ART to 11.0, 17.5, 20.7, 23.0, 25.3, and 27.0 years with ART in Eras 1 through 6, respectively. Of the total projected lifetime survival benefit of 9.3 million life-years, 16% (or 1.5 million life-years) has been realized as of December 2014. Conclusions Provision of ART through a national programme has led to dramatic survival benefits in Brazil, the majority of which are still to be realized. Improvements in initial and subsequent ART regimens and higher CD4 counts at ART initiation have contributed to these increasing benefits. PMID:27029828

    Cow's milk protein allergy (CMPA) is highly prevalent in infants (2-5%). It has a wide clinical spectrum, and confirmation through an oral food challenge (OFC) is relevant for its differential diagnosis. Information on this topic is scarce in Chile. To describe the demographic and clinical features of infants with suspected CMPA. A retrospective study of patients<1 year-old, treated for suspected CMPA between 2009 and 2011. Demographic data, symptoms of atopy, nutrition at the time of diagnosis, CMPA symptoms, diagnostic studies, and response to treatment were recorded. Diet response at least 4 weeks after milk modification, and clinical behavior when suspected foods were added back to the diet were considered standard diagnostic criteria. Descriptive statistics were performed using Epiinfo ™ software. The study included 106 infants, of whom, 51% male, 80% term newborns, 74% with≥1 atopic parent, and 34% with ≥1 parent/sibling with food allergy. The median age at onset of symptoms was 1.5 months (range 1.5-2m). Almost half (46%) were breast-feeding≥6m, with 15% receiving formula milk since the neonatal period, and 49% before the third month. Common symptoms were: vomiting (63%), colic (49%), and bleeding on passing stools (41%). No anaphylaxis was identified, and 61% had≥2 symptoms at debut. Only 34% were subjected to OFC. The most frequently requested tests were, test patch (43%), prick test (40%), and blood in stools (37%). 43% breast feeding with exclusion diet, 24% extensively hydrolysed formula, 26% amino acid formula, and 7% others. Demographic characteristics and risk factors were similar to those previously described in international literature. Clinical presentation was early in life, and digestive symptoms predominated. OFC was underused for diagnosis, and most of the tests requested did not change management. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Human and animal studies have revealed a strong association between periconceptional environmental factors, such as poor maternal diet, and an increased propensity for cardiovascular and metabolic disease in adult offspring. Previously, we reported cardiovascular and physiological effects of maternal low protein diet (LPD fed during discrete periods of periconceptional development on 6-month-old mouse offspring. Here, we extend the analysis in 1 year aging offspring, evaluating mechanisms regulating growth and adiposity. Isocaloric LPD (9% casein or normal protein diet (18% casein; NPD was fed to female MF-1 mice either exclusively during oocyte maturation (for 3.5 days prior to mating; Egg-LPD, Egg-NPD, respectively, throughout gestation (LPD, NPD or exclusively during preimplantation development (for 3.5 days post mating; Emb-LPD. LPD and Emb-LPD female offspring were significantly lighter and heavier than NPD females respectively for up to 52 weeks. Egg-LPD, LPD and Emb-LPD offspring displayed significantly elevated systolic blood pressure at 52 weeks compared to respective controls (Egg-NPD, NPD. LPD females had significantly reduced inguinal and retroperitoneal fat pad: body weight ratios compared to NPD females. Expression of the insulin receptor (Insr and insulin-like growth factor I receptor (Igf1r in retroperitoneal fat was significantly elevated in Emb-LPD females (P<0.05, whilst Emb-LPD males displayed significantly decreased expression of the mitochondrial uncoupling protein 1 (Ucp1 gene compared to NPD offspring. LPD females displayed significantly increased expression of Ucp1 in interscapular brown adipose tissue when compared to NPD offspring. Our results demonstrate that aging offspring body weight, cardiovascular and adiposity homeostasis can be programmed by maternal periconceptional nutrition. These adverse outcomes further exemplify the criticality of dietary behaviour around the time of conception on long-term offspring

  11. Do American dippers obtain a survival benefit from altitudinal migration?

    Directory of Open Access Journals (Sweden)

    David J Green

    Full Text Available Studies of partial migrants provide an opportunity to assess the cost and benefits of migration. Previous work has demonstrated that sedentary American dippers (residents have higher annual productivity than altitudinal migrants that move to higher elevations to breed. Here we use a ten-year (30 period mark-recapture dataset to evaluate whether migrants offset their lower productivity with higher survival during the migration-breeding period when they occupy different habitat, or early and late-winter periods when they coexist with residents. Mark-recapture models provide no evidence that apparent monthly survival of migrants is higher than that of residents at any time of the year. The best-supported model suggests that monthly survival is higher in the migration-breeding period than winter periods. Another well-supported model suggested that residency conferred a survival benefit, and annual apparent survival (calculated from model weighted monthly apparent survival estimates using the Delta method of residents (0.511 ± 0.038SE was slightly higher than that of migrants (0.487 ± 0.032. Winter survival of American dippers was influenced by environmental conditions; monthly apparent survival increased as maximum daily flow rates increased and declined as winter temperatures became colder. However, we found no evidence that environmental conditions altered differences in winter survival of residents and migrants. Since migratory American dippers have lower productivity and slightly lower survival than residents our data suggests that partial migration is likely an outcome of competition for limited nest sites at low elevations, with less competitive individuals being forced to migrate to higher elevations in order to breed.

    To examine the training and concomitant changes in laboratory- and field-test performance of highly trained endurance runners. Fourteen highly trained male endurance runners (mean ± SD maximal oxygen uptake [VO2max] 69.8 ± 6.3 mL · kg-1 · min-1) completed this 1-y training study commencing in April. During the study the runners undertook 5 laboratory tests of VO2max, lactate threshold (LT), and running economy and 9 field tests to determine critical speed (CS) and the modeled maximum distance performed above CS (D'). The data for different periods of the year were compared using repeated-measures ANOVA. The influence of training on laboratory- and field-test changes was analyzed by multiple regression. Total training distance varied during the year and was lower in May-July (333 ± 206 km, P = .01) and July-August (339 ± 206 km, P = .02) than in the subsequent January-February period (474 ± 188 km). VO2max increased from the April baseline (4.7 ± 0.4 L/min) in October and January periods (5.0 ± 0.4 L/min, P ≤ .01). Other laboratory measures did not change. Runners' CS was lowest in August (4.90 ± 0.32 m/s) and highest in February (4.99 ± 0.30 m/s, P = .02). Total training distance and the percentage of training time spent above LT velocity explained 33% of the variation in CS. Highly trained endurance runners achieve small but significant changes in VO2max and CS in a year. Increases in training distance and time above LT velocity were related to increases in CS.

    A robotic arm was developed by our laboratory for tele-operated echography on patients in locations isolated from a trained sonographer. The objective of the study was to evaluate, over a 1-year period, the use of the robotic arm for telesonography performed by a sonographer located at the University Hospital (Tours, France) on patients in two isolated medical centers 50 km away linked via the Internet. A nonsonographer operator (physician or paramedic) located the ultrasound probe attached to the robotic arm over the appropriate acoustic window for the organ of interest by rolling the whole robotic arm and mechanical support across the floor. The expert sonographer then telemanipulated the robotic arm via an Internet connection and adjusted the orientation of the probe until the most appropriate organ view for delivering a diagnosis was obtained. Three hundred telesonography examinations were performed within 1 year: 68 (22.7%) on abdominal organs, 20 (6.7%) on pelvic organs, 138 (46%) on supraaortic vessels (carotid artery), 33 (11%) on the thyroid, 30 (10%) on leg veins, and 11 (3.7%) on the kidney and urinary tract. Telesonography could not be achieved in 10 of the 300 cases due to poor image quality on obese patients or those presenting poor echogenicity. These cases were re-examined at the university hospital by a sonographer. The rate of telesonography exams over the 1-year period was 1.5 per day for the "general population" medical site and 1 per week for the "elderly patient" medical site. This study demonstrated that telesonography using a robotic arm can be routinely used for providing echographic diagnoses on patients isolated from imaging centers.

    Data on the use of deferiprone in young children with iron overload are limited. To study the safety profile of a liquid formulation of deferiprone in chelating young children with transfusion-induced iron overload. A daily dose of 50-100 mg/kg BW in three divided doses of oral deferiprone was given to young patients who had received at least ten packed red cell transfusions and achieved a serum ferritin level >1000 μg/L during a 12-month period from 2011 to 2012. Nine children (four males) diagnosed with various types of thalassaemia (n = 8) and hereditary spherocytosis (n = 1) were enrolled. Their mean (SD) age was 4.5 (1.9) years. The patients received 15-20 ml/kg BW of packed red cell transfusions every 4-8 weeks from a mean (SD) age of 2.1 (1.7) years to maintain a pre-transfusion haematocrit at 27%. A mean (SD) total of packed red cells of 5132 (2725) ml were given within a mean (SD) duration of 2.4 (1.1) years before the study. During the 1-year study period, they received a mean (SD) total of packed red cells of 2194 (680) ml or 138 (50) ml/kg BW with a mean (SD) daily iron load of 0.29 (0.12) mg/kg BW. The pre-treatment geometric mean of serum ferritin of 1863.8 μg/L decreased to 1279.7 μg/L after 1 year of treatment (P = 0.05). All patients tolerated the liquid formulation well and did not experience any gastro-intestinal discomfort, nausea or vomiting. The liquid formulation of deferiprone is safe in young children with transfusion-induced iron overload.

    Cancers exhibit differences in metastatic behavior and drug sensitivity that correlate with certain tumor-specific variables such as differentiation grade, growth rate/extent and molecular regulatory aberrations. In practice, patient management is based on the past results of clinical trials adjusted for these biomarkers. Here, it is proposed that treatment strategies could be fine-tuned upfront simply by quantifying tumorigenic spatial (cell growth) and temporal (genetic stability) control losses, as predicted by genetic defects of cell-cycle-regulatory gatekeeper and genome-stabilizing caretaker tumor suppressor genes, respectively. These differential quantifications of tumor dysfunction may in turn be used to create a tumor-specific 'periodic table' that guides rational formulation of survival-enhancing anticancer treatment strategies.

    To evaluate pelvic floor biometry in Chinese women 1 year following childbirth and to explore factors that affect it. Translabial ultrasound examination was performed at rest, on Valsalva maneuver (VM) and on pelvic floor muscle contraction (PFMC) in the first, second and third trimesters of pregnancy and at 8 weeks, 6 months and 12 months after delivery in a cohort of women delivering at term their first child. Offline analysis was undertaken to measure the position of the bladder neck, cervix, anorectal junction and hiatal dimensions at each posture and at each visit, and to detect levator ani muscle (LAM) injury on PFMC 8 weeks and 12 months after delivery. Results were analyzed according to mode of delivery. We recruited 442 women, of whom 328 (74.2%) completed the study; there was LAM injury in 48 women at 8 weeks and in only 38 women at 12 months. When comparing first-trimester biometry to that at 12 months after delivery, the bladder neck was more distal on VM and bladder neck displacement was increased, and the cervix was lower at rest and on VM in the vaginal delivery group. In the Cesarean section group, bladder neck and anorectal junction were more distal on VM, the cervix was lower at rest, on VM and on PFMC, and the hiatal area was increased on VM. There was a greater increase in hiatal area after vaginal delivery. Overall, 34.8% had irreversible hiatal distension (> 20% increase in hiatal area after delivery as compared to first trimester). LAM injury was significantly associated with irreversible hiatal distension (odds ratios, 5.2-9.5 at different postures). Pregnancy beyond 35 weeks of gestation has an effect on the pelvic floor of Chinese women, irrespective of mode of delivery. The pelvic organs remain more mobile after delivery when compared to in the first trimester, and there is no clear difference between the findings observed following vaginal delivery or Cesarean section, except in hiatal distension, which is greater after vaginal delivery

    In view of the conflicting guidelines issued by national and international scientific societies, debate about the indications for prophylactic extraction of wisdom teeth is ongoing. This prospective study was therefore set up to explore the complications associated with wisdom teeth and requiring in-patient treatment. From January /2003 to December 2003, 21 subjects were admitted for treatment of complications associated with wisdom teeth. The medical history was recorded for each of these patients, as were the cause and type of the complications. The parameter used to quantify the severity of any infections was the CRP, and the overall clinical complexity level of each case was assessed by the length of stay in hospital (and the duration of intensive care if this had been necessary). The characteristics of patients in the group with postoperative complications were compared to those of patients with complications attributable to pericoronitis. Moreover, complications in patients who had undergone prophylactic extraction of wisdom teeth that had not been causing any symptoms were compared with those in patients whose wisdom teeth had been extracted because of morbidity. Overall, 18 deep-space infections (15 abscesses, 2 inflammatory infiltrations, 1 case of phlegmonous cellulitis), 2 mandibular fractures and 1 lingual nerve injury were noted within 1 year. The complications resulted from surgical procedures in 15 of the 21 cases, while in 6 they had their origin in pericoronitis. Extensive surgery or intensive care was required only for patients with postoperative complications. The length of stay in hospital was significantly greater for patients with postoperative complications ( p= 0.007, U-test). However, 9 of these 15 patients reported preoperative episodes of infection. Thus, more than two thirds of the complications could be traced back to wisdom teeth that were causing symptoms. In our clinic's catchment area, infectious complications were more frequent and

    Although immature neonate survival has improved, there is an increased risk of developing bronchopulmonary dysplasia, leading to significant respiratory morbidity. Measures to reduce bronchopulmonary dysplasia are not always effective or have important adverse effects. To evaluate the effect of late surfactant administration in infants with prolonged respiratory distress on ventilation duration, respiratory outcome at 36 weeks' postmenstrual age, and at 1 year postnatal age. Double-blind randomized clinical trial at 13 level III French perinatal centers. Participants included 118 neonates at less than 33 weeks' gestation who still required mechanical ventilation on day 14 (SD, 2) with fraction of inspired oxygen of more than 0.30. All survivors were eligible for follow-up. We performed an intent-to-treat analysis. Infants received 200 mg/kg of poractant alfa (surfactant) or air after randomization. At 1 year, after parents' interview, infants underwent physical examination by pediatricians not aware of the randomization. The duration of ventilation was the primary outcome. The combined outcome of death or bronchopulmonary dysplasia at 36 weeks' postmenstrual age and respiratory morbidity at 1 year of age were the main secondary outcome measures. Of the 118 infants who participated in the study, 65 (55%) were male. Fraction of inspired oxygen requirements dropped after surfactant, but not air, for up to 24 hours after instillation (0.36 [0.11] vs 0.43 [0.18]; P surfactant-treated infants needed rehospitalization for respiratory problems after discharge (28.3% vs 51.1%; P = .03); 39.5% vs 50% needed respiratory physical therapy (P = .35). No difference was observed for weight (7.8 [1.2] kg vs 7.6 [1.1] kg), height (69 [5] cm vs 69 [3] cm), and head circumference (44.4 [1.7] cm vs 44.2 [1.7] cm) measured at follow-up, nor for neurodevelopment outcome. Late surfactant administration did not alter the early course of bronchopulmonary dysplasia. However, surfactant

    To assess the effectiveness and safety of the treatment with oral anticholinergic agents (Oxybutin clorure) in patients under 1 year old, and who aree carriers of high risk bladder secondary to neurological illness as well as no neurological one. Since 1989, we have indicated treatment with anticholinergic agents to 16 patients: 9 patients had neurogenic bladder secondary to: myelomeningocele (n=7) and sacrocoxigeal teratoma (n=2). Others 7 patients had non neurogenic bladder secondary to: posterior urethral valvulas (n=1), valvula-like syndrome (n=4), post-surgery of neonatal giant bladder diverticulum (n=1) and Prune-Belly syndrome (n=1). The urodinamic study was performed during the first six months of life, being "high risk bladder" defined according to the parameters of compliance vesical and pressure of leak at point (PER). Five of the patients showed neonatal cronic renal failure (CRF), who were treated by cutaneus temporary derivation. All patients at treatment with anticholinergic agents at a 0.2 mg/kg/day dose was established; other early adjunctive treatment prior to the closure of the urinary derivation in children with CRF(n=5); or as a part of the conservative treatment (n=3), alone or associate to intermittent bladder catheterization (IBC) (n=8). During the treatment with anticholinergic agents, the cardiac frequency was controlled by EKG registration in 6 patients, being the rest of the children clinicaly controled (skin colour, mouth dryness, cardiac frequency and intestinal function). In all the cases, the minimum duration of the treatment was one year, until the functional stabilization of the urinary tract. It is to underline the absence of secondary complications which would have caused the suspension or the reduction of the treatment at long term. Conventional studies of urologicals image and urodinamic studies, showed the stabilization of the urinary tract and also the preservation of kidney function and not only was demonstrated in those

    Modifications of histones, the chief protein components of the chromatin, have emerged as critical regulators of life and death. While the “apoptotic histone code” came to light a few years ago, accumulating evidence indicates that autophagy, a cell survival pathway, is also heavily regulated by histone-modifying proteins. In this review we describe the emerging “autophagic histone code” and the role of histone modifications in the cellular life vs. death decision. PMID:24429873

  11. Survivability is more fundamental than evolvability.

    Directory of Open Access Journals (Sweden)

    Michael E Palmer

    Full Text Available For a lineage to survive over long time periods, it must sometimes change. This has given rise to the term evolvability, meaning the tendency to produce adaptive variation. One lineage may be superior to another in terms of its current standing variation, or it may tend to produce more adaptive variation. However, evolutionary outcomes depend on more than standing variation and produced adaptive variation: deleterious variation also matters. Evolvability, as most commonly interpreted, is not predictive of evolutionary outcomes. Here, we define a predictive measure of the evolutionary success of a lineage that we call the k-survivability, defined as the probability that the lineage avoids extinction for k generations. We estimate the k-survivability using multiple experimental replicates. Because we measure evolutionary outcomes, the initial standing variation, the full spectrum of generated variation, and the heritability of that variation are all incorporated. Survivability also accounts for the decreased joint likelihood of extinction of sub-lineages when they 1 disperse in space, or 2 diversify in lifestyle. We illustrate measurement of survivability with in silico models, and suggest that it may also be measured in vivo using multiple longitudinal replicates. The k-survivability is a metric that enables the quantitative study of, for example, the evolution of 1 mutation rates, 2 dispersal mechanisms, 3 the genotype-phenotype map, and 4 sexual reproduction, in temporally and spatially fluctuating environments. Although these disparate phenomena evolve by well-understood microevolutionary rules, they are also subject to the macroevolutionary constraint of long-term survivability.

  12. Survival of pneumococcus on hands and fomites

    Full Text Available Abstract Background Pneumococcal hand contamination in Indigenous children in remote communities is common (37%. It is not clear whether this requires frequent inoculation, or if pneumococci will survive on hands for long periods of time. Thus the aim of this study was to determine the survival time of pneumococci on hands and fomites. Findings The hands of 3 adult volunteers, a glass plate and plastic ball were inoculated with pneumococci suspended in two different media. Survival at specified time intervals was determined by swabbing and re-culture onto horse blood agar. Pneumococci inoculated onto hands of volunteers were recovered after 3 minutes at 4% to 79% of the initial inoculum. Recovery from one individual was consistently higher. By one hour, only a small number of pneumococci were recovered and this was dependent on the suspension medium used. At subsequent intervals and up to 3 hours after inoculation, Conclusion The poor survival of pneumococci on hands suggests that the high prevalence of pneumococcal hand contamination in some populations is related to frequent inoculation rather than long survival. It is plausible that hand contamination plays a (brief role in transmission directly, and indirectly through contamination via fomites. Regular hand washing and timely cleansing or removal of contaminated fomites may aid control of pneumococcal transmission via these routes.

    Minor stroke is characterized by mild neurological functional impairment and relatively good outcome. Little is known about the association between post-stroke depression (PSD) and outcomes of minor stroke. The aim of this study was to investigate the association between PSD and disability and quality of life (QoL) at 1 year after minor ischemic stroke. Patients with first-ever minor ischemic stroke (n = 747) were followed up at 14 ± 2 days, 3 months, 6 months, and 1 year after stroke. Depressive symptoms were assessed at each follow-up. Patients diagnosed with depression at 14 ± 2 days formed the early-onset PSD group; those who were diagnosed with depression at any subsequent follow-ups for the first time constituted the late-onset PSD group. The outcomes of minor stroke including disability (modified Rankin score ≥ 2) and QoL (Short Form-36 Health Survey) were assessed at the 1-year follow-up. A total of 198 (26.5%) patients were diagnosed with PSD over the 1-year follow-up; 136 and 62 patients were allocated to the early-onset PSD group and late-onset PSD group, respectively. Both early-onset and late-onset PSD were independently associated with disability and poor physical and mental health at 1 year after stroke. Recovery from depression (n = 112) within 1 year decreased the adverse impacts of PSD on functional outcome and QoL. Post-stroke depression was independently associated with disability and poor QoL at 1 year after first-ever minor ischemic stroke. Recovery from PSD decreased but did not eliminate the adverse impacts of PSD on outcomes of minor stroke. Copyright © 2015 John Wiley & Sons, Ltd.

    The survival experience of 582 women with premenopausal breast cancer was examined to determine whether prognosis was related to body size or to demographic and reproductive factors. During the follow-up period 228 patients died and 18 emigrated or were lost to follow-up. Usual body weight, reported at the time of diagnosis, was a strong predictor of survival, with a statistically significant trend towards lower survival with increasing weight. Height and obesity (Quetelet index) were not significantly related to survival, although the tallest women and the most obese women appeared to fare worst. Other characteristics of prognostic importance were disease stage and reproductive history (women who were older when their first child was born fared better). Women aged 46-50 when diagnosed also appeared more likely to survive but no clear trend with age was evident. Other characteristics of the women including social class, cigarette use and oral contraceptive use were not significantly related to survival probability. PMID:3994912

    To analyze the control of intraocular pressure (IOP) and corneal graft survival after implantation of Ahmed glaucoma device (AGD) in eyes that had high-risk penetrating keratoplasty (PK). This is a retrospective noncomparative case series of 59 eyes that had high-risk PK and underwent AGD insertion. The primary outcome measures are the control of IOP between 6 and 21 mm Hg and corneal graft survival. The secondary outcome measures are risk factors associated with IOP control and corneal graft survival. The mean IOP reduced significantly after the AGD procedure (26.45 ± 6.8 mm Hg preoperatively vs. 16.85 ± 7.4 mm Hg, 16.95 ± 4.6 mm Hg, 17.97 ± 5.7 mm Hg, 15.78 ± 5.2 mm Hg, and 15.59 ± 5.5 mm Hg, at 1 month, 6 months, 1 year, 2 years, and at the last follow-up postoperatively; P IOP control was successful in 44 eyes (75.8%). IOP control was successful in 96% of the eyes at 1 year, 87% at 2 years, 83% at 3 years, and 83% at 5 years. The percentage of clear corneal grafts after 1, 2, 3, and 5 years following the AGD insertion were 87%, 77%, 65%, and 47%, respectively. Further surgery after AGD insertion was associated with 1.79 times greater risk of failure of IOP control. AGD was effective in controlling the IOP associated with high-risk PK over a 5-year period. Postvalve surgery doubles the risk of failure of IOP control.

    Gastrointestinal stromal tumors (GISTs) are the most commonly diagnosed mesenchymal tumors of the gastrointestinal tract. The risk of recurrence following surgical resection of GISTs is typically reported from the date of surgery. However, disease-free survival (DFS) over time is dynamic and changes based on disease-free time already accumulated following surgery. To assess the comparative performance of established GIST recurrence risk prognostic scoring systems and to characterize conditional DFS following surgical resection of GISTs. A retrospective cohort study of 502 patients who underwent surgery for a primary, nonmetastatic GIST between January 1, 1998, and December 31, 2012, at 7 major academic cancer centers in the United States and Canada. Disease-free survival of the patients was classified according to 5 prognostic scoring systems, including the National Institutes of Health criteria, modified National Institutes of Health criteria, Memorial Sloan Kettering Cancer Center GIST nomogram, and American Joint Committee on Cancer gastric and nongastric categories. The concordance index (also known as the C statistic or the area under the receiver operating curve) of established GIST recurrence risk prognostic scoring systems. Conditional DFS estimates were calculated. Overall 1-year, 3-year, and 5-year DFS following resection of GISTs was 95%, 83%, and 74%, respectively. All the prognostic scoring systems had fair prognostic ability. For all tumor sites, the American Joint Committee on Cancer gastric category demonstrated the best discrimination (C = 0.79). Using conditional DFS, the probability of remaining disease free for an additional 3 years given that a patient was disease free at 1 year, 3 years, and 5 years was 82%, 89%, and 92%, respectively. Patients with the highest initial recurrence risk demonstrated the greatest increase in conditional survival as time elapsed. Conditional DFS improves over time following resection of GISTs. This is valuable

    We report menstrual and mid-cycle patterns of self-reported “fluid retention” in 765 menstrual cycles in 62 healthy women. Self-reported “fluid retention,” commonly described as bloating, is one element of the clinical assessment and diagnosis of premenstrual symptoms. These daily diary data were collected as part of an observational prospective one-year study of bone changes in healthy women of differing exercise characteristics. Ovulation was documented by quantitative basal temperature analysis, and serum estradiol and progesterone levels were available from initial and final cycles. Fluid retention scores (on a 0–4 scale) peaked on the first day of menstrual flow (mean ± SE : 0.9 ± 0.1), were lowest during the mid-follicular period, and gradually increased from 0.22 ± 0.05 to 0.50 ± 0.09 over the 11 days surrounding ovulation. Mid-cycle, but not premenstrual, fluid scores tended to be lower in anovulatory cycles (ANOVA P = 0.065), and scores were higher around menstruation than at midcycle (P cycles. PMID:21845193

    Emotional and behavioral problems at an early age can reasonably be considered a high-risk factor for later mental health disorders. The aim of the article is to reveal predictive factors of 1½-year-old children's emotional and behavioral problems. The study was a part of a prospective birth-cohort study. The study sample consisted of 172 full-term infants (born during Gestational Weeks 37-42) and their mothers. Emotional and behavioral problems at the age of 1½ years were measured using the Child Behavior Checklist for Ages 1½-5 (T. Achenbach & L. Rescorla, 2000), which was completed by mothers. Emotional and behavioral problems at age of 1½ years were more prevalent in infants born via cesarean section, as compared to infants born vaginally without administration of medication. Newborns' suboptimal functioning after birth, complicated emotional acceptance of pregnancy, a couple's nonsatisfactory relationship during pregnancy, maternal distress during pregnancy and in the first months after childbirth, and inflexible and parent-oriented attitudes toward infant-rearing also predicted children's emotional and behavioral problems independent of sociodemographic factors. Results suggest that biomedical and psychosocial factors which manifest themselves in the prenatal and perinatal periods can have associations with later infant and child mental health. © 2016 Michigan Association for Infant Mental Health.

    In order to investigate various options for reduction of the district heating return temperature and for introduction of energy saving measures in the buildings, a demonstration area comprising eight buildings was selected. The eight buildings selected were typical 5-floor buildings built in 1982-89. This enabled the experience to be transferred to a maximum number of buildings in Klaipeda and in Lithuania, in general. All buildings had a one-string radiator system installed. Since 1991, the supply temperature in Klaipeda district heating system has been reduced. This has led to a lower indoor temperature, which has decreased from the design value 18 deg. C to 15 dec. C due to shortage of fuel. With such a low room temperature, the improved sytems may result in better comfort rather than in energy savings. The project has been implemented during a two-year period from heating season 97/98 to 98/99. The first year before the heating season 97/98, energy and flow meters were installed for measuring the existing heating and hot water consumption. For the next heating season 1998/1999, various energy saving measures were installed, and measurements were caried out again. After that, the energy consumption and temperature levels were analysed and compared for the two seasons. (au)

    Bleaching materials containing hydrogen peroxide have been used for treating discolored nonvital teeth but their use was occasionally associated with external root resorption. In a previous study it was found that the immediate results of bleaching teeth in vitro were equal for sodium perborate mixed with either water or hydrogen peroxide. The purpose of this study was to compare the bleaching prognosis of sodium perborate mixed with water or hydrogen peroxide over a 1-yr period. Extracted human teeth with intact crowns were discolored with human erythrocytes and bleached by sodium perborate mixed with either 30% hydrogen peroxide (group A), 3% hydrogen peroxide (group B), or water (group C). The bleaching materials were placed in the pulp chambers of the discolored teeth and sealed with IRM. They were replaced with fresh preparations after 3 and 7 days. After 14 days the coronal access cavities were sealed with composite resin and the teeth photographed with a color slide film under standardized conditions. The teeth were stored in artificial saliva for 1 yr and photographed after 3, 6, and 12 months. Two separate evaluators ranked the teeth by comparing them with the shades before and after bleaching. The bleaching success rates of the tested groups at each time interval were compared and analyzed statistically. It was found that after 1 yr all of the teeth in groups A and C maintained their shades. In 20% of the teeth in group B there was color regression. Statistically, these differences were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

    This study assessed the longer-term (12-month) variability in post-exercise heart rate recovery following a submaximal exercise test. Longitudinal data was analysed for 97 healthy middle-aged adults (74 male, 23 female) from 2 occasions, 12 months apart. Participants were retrospectively selected if they had stable physical activity habits, submaximal treadmill fitness and anthropometric measurements between the 2 assessment visits. A submaximal Bruce treadmill test was performed to at least 85% age-predicted maximum heart rate. Absolute heart rate and Δ heart rate recovery (change from peak exercise heart rate) were recorded for 1 and 2 min post-exercise in an immediate supine position. Heart rate recovery at both time-points was shown to be reliable with intra-class correlation coefficient values ≥ 0.714. Absolute heart rate 1-min post-exercise showed the strongest agreement between repeat tests (r = 0.867, P heart rate values rather than Δ heart rate recovery, and for 1-min rather than 2-min post-exercise recovery time points. Log-transformed values generated better variability with acceptable coefficient of variation for all measures (2.2-10%). Overall, 1 min post-exercise heart rate recovery data had least variability over the 12-month period in apparently healthy middle-aged adults. © Georg Thieme Verlag KG Stuttgart · New York.

    Peatland testate amoebae (TA) are well-established bioindicators for depth to water table (DWT), but effects of hydrological changes on TA communities have never been tested experimentally. We tested this in a field experiment by placing Sphagnum carpets (15 cm diameter) collected in hummock, lawn and pool microsites (origin) at three local conditions (dry, moist and wet) using trenches dug in a peatland. One series of samples was seeded with microorganism extract from all microsites. TA community were analysed at T0: 8-2008, T1: 5-2009 and T2: 8-2009. We analysed the data using conditional inference trees, principal response curves (PRC) and DWT inferred from TA communities using a transfer function used for paleoecological reconstruction. Density declined from T0 to T1 and then increased sharply by T2. Species richness, Simpson diversity and Simpson evenness were lower at T2 than at T0 and T1. Seeded communities had higher species richness in pool samples at T0. Pool samples tended to have higher density, lower species richness, Simpson diversity and Simpson Evenness than hummock and/or lawn samples until T1. In the PRC, the effect of origin was significant at T0 and T1, but the effect faded away by T2. Seeding effect was strongest at T1 and lowest vanished by T2. Local condition effect was strong but not in line with the wetness gradient at T1 but started to reflect it by T2. Likewise, TA-inferred DWT started to match the experimental conditions by T2, but more so in hummock and lawn samples than in pool samples. This study confirmed that TA responds to hydrological changes over a 1-year period. However, sensitivity of TA to hydrological fluctuations, and thus the accuracy of inferred DWT changes, was habitat specific, pool TA communities being least responsive to environmental changes. Lawns and hummocks may be thus better suited than pools for paleoecological reconstructions. This, however, contrasts with the higher prediction error and species' tolerance for

    Post-treatment periapical lesions present 1 year after treatment may heal during the second year or later. The aim of this study was to assess second-year volumetric changes in post-treatment periapical radiolucencies detected 1 year after treatment. Post-treatment periapical radiolucencies were detected on cone-beam computed tomographic (CBCT) scans obtained from 93 single-rooted teeth 1 year after endodontic treatment. The outcome of these teeth was evaluated 2 years after treatment. Two examiners independently measured the volume of the radiolucencies on CBCT images twice. A Wilcoxon signed rank test was used to assess the 1- and 2-year post-treatment volumes. The intraclass correlation coefficients for the CBCT volumetric measurements were 0.971 and 0.998 for the 2 examiners, and the interexaminer correlation coefficient was 0.998. Of the 93 teeth with post-treatment radiolucencies at 1 year, 61were examined at the second-year evaluation. The overall size of the radiolucencies significantly decreased during the second year (P = .01); the volume decreased in 38 teeth (63%), remained unchanged in 20 (33%), and increased in 2 (3%). The volume of post-treatment periapical radiolucencies detected 1 year after treatment was significantly reduced after the second year in 63% of teeth. Copyright © 2015. Published by Elsevier Inc.

    Determine survival and factors affecting survival for patients with malignant tumors of odontogenic origin. Retrospective analysis of the National Cancer Institute's SEER database (Surveillance, Epidemiology, and End Results). Tertiary medical center. All cases of malignant tumors of odontogenic origin were extracted from the SEER database for the period of 1973 to 2011. Demographic, tumor-specific, and survival data were tabulated and Kaplan-Meier survival analysis conducted according to histopathologic results. Cox regression analysis stratified for histopathology was conducted to determine factors that influenced survival. A total of 308 cases of malignant tumors with odontogenic origin were analyzed. Malignant ameloblastoma accounted for 59.7% of cases, followed by malignant odontogenic tumor (35.4%; including odontogenic carcinoma, odontogenic sarcoma, primary intraosseous carcinoma, and ameloblastic carcinoma) and ameloblastic fibrosarcoma (2.9%). The overall mean and median were 229 and 227 months, respectively, while the 5-year survival rate was 81% for the entire cohort. Malignant ameloblastoma exhibited the best mean survival (237 months), whereas malignant odontogenic tumor (139 months) and ameloblastic fibrosarcoma (42 months) had lower mean survival rates. Younger age, surgery with adjuvant radiation, and smaller tumor size were found to improve survival. Significantly different survival can be expected depending on individual tumor histopathology, tumor size, age at diagnosis, and treatment modality. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    North American populations of northern pintails (Anas acuta) declined between 1979 and the early 1990s. To determine if low survival during winter contributed to declines, we estimated winter (last week of Aug-Feb 1987-90) survival for 190 adult (after hatching yr [AHY]) female radio-tagged pintails in late summer in Sacramento Valley (SACV), California. Survival rates did not vary by winter (P = 0.808), among preseason, hunting season, or postseason intervals (P = 0.579), or by body mass at time of capture (P = 0.127). Premolt (wing) pintails (n = 10) tended to survive at a lower rate (0.622, SE = 0.178) than pintails that had already replaced flight feathers (0.887, SE = 0.030) (P = 0.091). The pooled survival (all years) estimate for the 180-day winter was 0.874 (SE = 0.031). Hunting mortality rate (0.041-0.087) and nonhunting mortality rate (0.013-0.076) did not differ among years (P = 0.332) or within years (all P > 0.149). Legal hunting (n = 7), predation (n = 4), cholera (n = 2), illegal shooting (n = 2), botulism (n = 1), and unknown cause (n = 1) accounted for all mortality. Nonwintering survival (annu. survival/winter survival = 0.748) was lower than winter survival; thus, if gains in annual survival are desired for this population, managers should first examine the breeding-migration period for opportunities to achieve increases.

    The talk is concerned with the modelling of wave propagation in and vibration of periodic elastic structures. Although analysis of wave-guide properties of infinite periodic structures is a well establish research subject, some issues have not yet been fully addressed in the literature. The aim...... of the talk is to illustrate these issues in simple examples and to discuss possible applications and generalisations. First, the eigenfrequency spectra of finite periodic structures are compared with the location of stop-bands for their infinite counterparts for a hierarchy of four mathematical models....... In each case, special attention is paid to eigenfrequencies and eigenmodes of a single periodicity cell with appropriate boundary conditions. The influence of the amount of periodicity cells in a finite compound structure on its eigenfrequency spectrum is analyzed. Several features common...

  15. Periods and Nori motives

    CERN Document Server

    Huber, Annette

    2017-01-01

    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

    2016-01-01

    Applied Survival Analysis Using R covers the main principles of survival analysis, gives examples of how it is applied, and teaches how to put those principles to use to analyze data using R as a vehicle. Survival data, where the primary outcome is time to a specific event, arise in many areas of biomedical research, including clinical trials, epidemiological studies, and studies of animals. Many survival methods are extensions of techniques used in linear regression and categorical data, while other aspects of this field are unique to survival data. This text employs numerous actual examples to illustrate survival curve estimation, comparison of survivals of different groups, proper accounting for censoring and truncation, model variable selection, and residual analysis. Because explaining survival analysis requires more advanced mathematics than many other statistical topics, this book is organized with basic concepts and most frequently used procedures covered in earlier chapters, with more advanced topics...

    It has been suggested that a 6-day dexamethasone course combined with adrenaline may significantly reduce the admission rate in outpatients. It has also been suggested that prednisolone may reduce recurrent wheezing. Our aim was to investigate whether treatment with steroids, especially high dose dexamethasone, is associated with the length of hospitalization or with recurrent wheezing. A prospective-retrospective observational study was performed from January 2009 to December 2011 in a secondary care hospital. Eighty previously healthy patients aged 7-180 days who were hospitalized with a first episode of acute bronchiolitis (AB) were studied. AB treatment was at the attending physician's discretion, among those tested for AB with some benefit. Eligible drugs included bronchodilators and steroids. Primary short-term outcome studied was days of hospitalization. Primary long term outcome was "recurrent wheezing". Median length of hospitalization was 6 days for all groups. Patients treated with dexamethasone (1 mg/kg/day for 1 day, plus 0.6 mg/kg/day for 5 days) had an average length of hospitalization of 6.8 ± 3.1 (range, 4-20) days, those on prednisolone (prednisolone 1-2 mg/kg/day for 5 days) 7.0 ± 2.6 (range, 4-12) days and those with no steroids 6.6 ± 3.3 (3-21) days (no significant differences). The analysis showed no evidence of association of any management schedule with recurrent wheezing. After adjusting long-term outcome variables for potential confounders, comparisons remained no different. High dose dexamethasone or medium-dose prednisolone during AB provided no benefit in a short or long-term period in young, previously healthy hospitalized infants.

    Pharmacists conduct medication reviews to optimize drug therapy. Each jurisdiction implements and funds these programs differently. To describe the uptake of the first year of a community pharmacy medication review program reimbursed by the publically insured seniors' drug benefit program in Nova Scotia, Canada. This retrospective analysis included 294 pharmacies and 105,000 beneficiaries enrolled in the Nova Scotia Seniors' Pharmacare Program. Prescription and service claims data from this program were analyzed to determine type and number of beneficiaries receiving a medication review, number and predictors of pharmacies completing reviews, and number of prescribed medications 6-months before and 6-months after the review. 428 medication reviews were conducted and billed by 33% of Nova Scotia pharmacies (1-50 reviews per pharmacy per year). The mean number and range of medications before the review were 10.8 (4-28) and following the review 10.4 (0-24), with an average decrease of 0.4 medications (95% CI 0.1-0.6), p=.0043). Patients receiving a review had a mean age of 75.2 years; 64.9% were female. Most pharmacies conducted reviews when patients reached their annual copayment (93%). Approximately 33% of pharmacies billed at least one medication review in the first year of the program. In spite of a $150 reimbursement per community pharmacy medication review, only 428 reviews were conducted over a 13-month period for a population of over 100,000 seniors. Results suggest financial reimbursement alone is not sufficient to implement a medication management program; health systems need to determine patient, pharmacist, pharmacy and health system level strategies to implement medication reviews more broadly.

    Childhood and adolescent cancers are uncommon, but they have important economic and health impacts on patients, families, and health care systems. Few studies have measured the economic burden of care for childhood and adolescent cancers. To estimate costs of cancer care in population-based cohorts of children and adolescents from the public payer perspective. We identified patients with cancer, aged 91 days to 19 years, diagnosed from 1995 to 2009 using cancer registry data, and matched each to three noncancer controls. Using linked administrative health care records, we estimated total and net resource-specific costs (in 2012 Canadian dollars) during 90 days prediagnosis and 1 year postdiagnosis. Children (≤14 years old) numbered 4,396: 36% had leukemia, 21% central nervous system tumors, 10% lymphoma, and 33% other cancers. Adolescents (15-19 years old) numbered 2,329: 28.9% had lymphoma. Bone and soft tissue sarcoma, germ cell tumor, and thyroid carcinoma each comprised 12% to 13%. Mean net prediagnosis costs were $5,810 and $1,127 and mean net postdiagnosis costs were $136,413 and $62,326 for children and adolescents, respectively; the highest were for leukemia ($157,764 for children and $172,034 for adolescents). In both cohorts, costs were much higher for patients who died within 1 year of diagnosis. Inpatient hospitalization represented 69% to 74% of postdiagnosis costs. Treating children with cancer is costly, more costly than treating adolescents or adults. Substantial survival gains in children mean that treatment may still be very cost-effective. Comprehensive age-specific population-based cost estimates are essential to reliably assess the cost-effectiveness of cancer care for children and adolescents, and measure health system performance.

    Cardiac transplantation has evolved from an experiment to an accepted therapy for severe heart failure. Increasing competition for donor organs mandates a greater emphasis on selection and timing for transplantation and paradoxically forces more reliance on aggressive medical therapy for all patients after evaluation. The growth of recipient and donor pools may enhance the opportunity for assessing histocompatibility, for which distinguishing between autoantibodies and human leukocyte antigen-determined reactivity is important, and some general nonresponders may be detected. Therapy with cyclosporine has improved the outcome after transplantation, but further refinement is needed, perhaps with pharmacologic synergy, to minimize nephrotoxicity and maximize specific immunosuppression. Survival is more than 80% at 1 year, after which the incidence of acute rejection and infection declines and accelerated atherosclerosis becomes prominent. Although resuming employment is not always possible, the overall quality of life is excellent after cardiac transplantation. Images PMID:3074557

    To retrospectively evaluate and compare two regenerative periodontal procedures in young individuals with aggressive periodontitis (AgP). Thirty-two patients aged 14-25 years (mean ± SD 19.3 ± 5.7) were diagnosed as having AgP with multiple intra-bony defects (IBDs) and treated by one of two regenerative modalities of periodontal therapy: guided tissue regeneration (GTR) using deproteinized bone xenograft (DBX) particles and a resorbable membrane (the GTR group), or an application of enamel matrix derivatives (EMD) combined with DBX (the EMD/DBX group). Periodic monitoring of treated sites included recording of probing depth (PD), clinical attachment level (CAL) and gingival recession. Pre-treatment and 1-year post-operative findings were statistically analysed within and between groups. The PD and CAL values decreased significantly with time, but not those between study groups. The mean pre-treatment and 1-year post-treatment PDs of the IBDs of the GTR group (n = 16; sites = 67) were 8.93 ± 1.14 mm and 3.58 ± 0.50 mm, respectively, and the mean CALs were 9.03 ± 1.03 mm and 4.16 ± 0.53 mm respectively. The mean PDs of the EMD/DBX group (n = 16; sites = 73) were 8.77 ± 1.04 mm and 3.61 ± 0.36 mm, respectively, and the mean CALS were 8.79 ± 1.04 mm and 3.77 ± 0.22 mm respectively (p < 0.001 for all). Surgical treatment of AgP patients by either GTR or by application of EMD/DBX yielded similarly successful clinical results at 1-year post-treatment. © 2015 John Wiley & Sons A/S.

    The advantages of platform switching using narrower abutments remain controversial. Many researchers suggest that platform switching can yield enhanced clinical results, while others remain skeptical. We hypothesize that the effectiveness of platform switching might be associated with the degree of reduction in size of the abutment. To radiographically and clinically examine a new abutment design created to move the implant-abutment interface farther medially. This was a prospective, randomized controlled clinical trial that included 27 patients (41 MIS Lance Plus® implants; MIS Implant Technologies, Karmiel, Israel). The patients' age ranged from 39 to 75 years. At the second stage of the surgery, the implants were randomly assigned to either the new platform switch Tulip abutment (TA) design or to the standard platform abutment (SA). Implant probing depth (IPD) and bleeding on probing (BOP) were recorded at baseline and after 12 months. Standardized periapical radiographs were taken (at baseline and at 12 months) and the marginal bone height measured. All implants were successfully integrated. The mean IPD at 1 year post-op was 2.91 mm for the SA group and 2.69 mm for the TA group (p > .05). Similarly, the BOP at 1 year was almost identical in both groups. The mean values of bone resorption at baseline were 0.98 ± 0.37 mm and 0.69 ± 0.20 for the TA and SA groups, respectively (p > .05). Bone loss (baseline to 12 months) was significantly greater in the SA group compared with the TA group. Use of the new TA, with its significantly downsized diameter, resulted in reduced bone loss at 1 year. Further research will be required to assess the long-term effect of this abutment on peri-implant health. © 2014 Wiley Periodicals, Inc.

    The purpose of this study was to evaluate the long-term effectiveness and safety of blonanserin, a second-generation antipsychotic drug developed in Japan, in patients with first-episode schizophrenia. Twenty-three antipsychotic-naïve patients with first-episode schizophrenia were treated within an open-label, 1-year, prospective trial of blonanserin (2-24 mg/day). Clinical evaluations were conducted at baseline and 2, 6, and 12 months after the start of treatment. The main outcome measures were changes in subjective well-being and subjective quality of life, as assessed by the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version and the Schizophrenia Quality of Life Scale-Japanese version, respectively. Secondary outcome measures included the Positive and Negative Syndrome Scale, the Brief Assessment of Cognition in Schizophrenia-Japanese version, laboratory tests, bodyweight, and extrapyramidal symptoms. Fourteen patients (60.9%) remained on the study at 1 year. In the intention-to-treat analysis, significant improvements were observed in several subscales on the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version, the Schizophrenia Quality of Life Scale-Japanese version, and the Brief Assessment of Cognition in Schizophrenia-Japanese version, and in all factor scores on the Positive and Negative Syndrome Scale. Improvement in depressive symptoms with blonanserin treatment was positively correlated with improvements in subjective well-being and subjective quality of life, as well as verbal memory. No significant changes were noted for any safety measure during the 1-year study period. Blonanserin was well tolerated and effective for the treatment of first-episode schizophrenia in terms of subjective wellness, cognition, and a wide range of pathological symptoms. Further large-scale studies are warranted to confirm our findings. © 2014 The Authors. Psychiatry and Clinical Neurosciences © 2014

    To evaluate the responsiveness to change of a modified version of the Work module of the Disabilities of the Arm, Shoulder, and Hand (DASH-W) in a prospective, longitudinal cohort study of active workers. We compared change on a 1-year recall modified DASH-W to change on work ability, work productivity, and symptom severity, according to predetermined hypotheses following the Consensus-based standards for the selection of health measurement instruments (COSMIN). We evaluated concordance in the direction of change, and magnitude of change using Spearman rank correlations, effect sizes (ES), standardized response means (SRM), and area under the receiver operating characteristic curves (AUC). In a sample of 551 workers, change in 1-year recall modified DASH-W scores showed moderate correlations with changes in work ability, work productivity, and symptom severity (r = 0.47, 0.44, and 0.36, respectively). ES and SRM were moderate for 1-year recall modified DASH-W scores in workers whose work ability (ES = -0.58, SRM = -0.52) and work productivity improved (ES = -0.59, SRM = -0.56), and larger for workers whose work ability (ES = 1.24, SRM = 0.68) and work productivity worsened (ES = 1.02, SRM = 0.61). ES and SRM were small for 1-year recall modified DASH-W scores of workers whose symptom severity improved (-0.32 and -0.29, respectively). Responsiveness of the 1-year recall modified DASH-W was moderate for those whose symptom severity worsened (ES = 0.77, SRM = 0.50). AUC met responsiveness criteria for work ability and work productivity. The 1-year recall modified DASH-W is responsive to changes in work ability and work productivity in active workers with upper extremity symptoms.

    The problem of designing a cost-efficient network that survives the failure of one or more nodes or edges of the network is critical to modern telecommunications engineering. The method developed in this book is designed to solve such problems to optimality. In particular, a cutting plane approach is described, based on polyhedral combinatorics, that is ableto solve real-world problems of this type in short computation time. These results are of interest for practitioners in the area of communication network design. The book is addressed especially to the combinatorial optimization community, but also to those who want to learn polyhedral methods. In addition, interesting new research problemsare formulated.

    Very low energy diets (VLED) appear to be the most efficacious dietary-based obesity reduction treatments in obstructive sleep apnea (OSA); however, effective weight loss maintenance strategies remain untested in this condition. Our study aimed to assess the feasibility, tolerability and efficacy of two common maintenance diets during a 10-month follow-up period after rapid weight loss using a 2-month VLED. In this two-arm, single-centre, open-label pilot trial, obese adult OSA patients received a 2-month VLED before being allocated to either the Australian Guide to Healthy Eating diet (AGHE) or a low glycaemic index high-protein diet (LGHP). Outcomes were measured at 0, 2 and 12 months. We recruited 44 patients [113.1 ± 19.5 kg, body mass index (BMI): 37.2 ± 5.6 kg m(-2) , 49.3 ± 9.2 years, 12 females]. Twenty-four patients were on continuous positive airway pressure (CPAP) or mandibular advancement splint (MAS) therapy for OSA. Forty-two patients completed the VLED. The primary outcome of waist circumference was reduced by 10.6 cm at 2 months [95% confidence interval (CI): 9.2-12.1], and patients lost 12.9 kg in total weight (95% CI: 11.2-14.6). There were small but statistically significant regains in waist circumference between 2 and 12 months [AGHE = 3.5 cm (1.3-5.6) and LGHP = 2.8 cm (0.6-5.0]. Other outcomes followed a similar pattern of change. After weight loss with a 2-month VLED in obese patients with OSA, a structured weight loss maintenance programme incorporating commonly used diets was feasible, tolerable and efficacious for 10 months. This programme may be deployed easily within sleep clinics; however, future research should first test its translation within general clinical practice. © 2017 European Sleep Research Society.

    The prospective 1-year EPIC study enrolled 341 patients with myelodysplastic syndromes (MDS); although baseline iron burden was >2500ng/mL, approximately 50% were chelation-naïve. Overall median serum ferritin decreased significantly at 1 year (p=0.002). Decreases occurred irrespective of whether...... patients were chelation-naïve or previously chelated; changes were dependent on dose adjustments and ongoing iron intake.

    Full Text Available We show that any mean-periodic function f can be represented in terms of exponential-polynomial solutions of the same convolution equation f satisfies, i.e., u∗f=0(μ∈E′(ℝn. This extends to n-variables the work of L. Schwartz on mean-periodicity and also extends L. Ehrenpreis' work on partial differential equations with constant coefficients to arbitrary convolutors. We also answer a number of open questions about mean-periodic functions of one variable. The basic ingredient is our work on interpolation by entire functions in one and several complex variables.

    OBJECTIVES To determine whether simple functional indicators are predictors of survival prognosis in very old adults. DESIGN In-person survey conducted over a 3-month period in 1998; assessment of survival over a 15-year follow-up period. SETTING Denmark. PARTICIPANTS All 3,600 Danes born in 1905 and living in Denmark in 1998, were invited to participate regardless of residence and health; 2,262 (63%) participated in the survey: 1,814 (80.2%) in person and 448 (19.8%) through a proxy. MEASUREMENTS Socioeconomic factors, medications and diseases, activities of daily living, physical performance, cognition, depression symptomatology, self-rated health, and all-cause mortality, evaluated as average remaining lifespan and chance of surviving to 100 years. RESULTS Men aged 92 to 93 had an overall 6.0% chance of surviving to 100 years, whereas the chance for women was 11.4%. Being able to rise without use of hands increased the chance for men to 11.2% (95% confidence interval (CI) = 7.7–14.7) and for women to 22.0% (95% CI = 18.9–25.1). When combining this with a Mini-Mental State Examination (MMSE) scores from 28 to 30, the chances were 21.7% (95% CI = 11.5–31.9) for men and 34.2% (95% CI = 24.8–43.5) for women. CONCLUSION Chair stand score combined with MMSE score is a quick and easy way to estimate overall chance of survival in very old adults, which is particularly relevant when treatment with potential side effects for nonacute diseases is considered.

    The Eurasian woodcock Scolopax rusticola is a popular game bird in much of Europe. However, little is known about its population dynamics. We estimated winter survival of woodcock in a protected area with no hunting in central Italy. We radio-tagged 68 woodcocks with battery-powered radio-transmitters during 2001-2005. Woodcocks were captured in fields at night from November through February and fitted with radios. Birds were classified on capture as juveniles or adults using plumage characteristics. Woodcocks were relocated daily through March of each year or until they died, disappeared from the study area, or until their radio failed. We constructed a set of eight competing models of daily survival for the period 1 December - 28 February. Estimates of survival were obtained using the program SURVIV and Akaike's Information Criteria. The best model suggested daily survival was a constant 0.9985 (95% CI = 0.9972-0.9998), corresponding to a survival rate of 0.88 (SE = 0.05) for the 90-day winter study period. Our estimate of juvenile survival is higher than previously reported, and may reflect the protected status of the study area. Our estimates of winter survival may be helpful in managing harvested woodcock populations as well as in conserving populations in an increasingly urbanised environment. ?? Wildlife Biology (2008).

  19. Winter survival of Scots pine seedlings under different snow conditions.

    Future climate scenarios predict increased air temperatures and precipitation, particularly at high latitudes, and especially so during winter. Soil temperatures, however, are more difficult to predict, since they depend strongly on the fate of the insulating snow cover. 'Rain-on-snow' events and warm spells during winter can lead to thaw-freeze cycles, compacted snow and ice encasement, as well as local flooding. These adverse conditions could counteract the otherwise positive effects of climatic changes on forest seedling growth. In order to study the effects of different winter and snow conditions on young Scots pine (Pinus sylvestris L.) seedlings, we conducted a laboratory experiment in which 80 1-year-old Scots pine seedlings were distributed between four winter treatments in dasotrons: ambient snow cover (SNOW), compressed snow and ice encasement (ICE), flooded and frozen soil (FLOOD) and no snow (NO SNOW). During the winter treatment period and a 1.5-month simulated spring/early summer phase, we monitored the needle, stem and root biomass of the seedlings, and determined their starch and soluble sugar concentrations. In addition, we assessed the stress experienced by the seedlings by measuring chlorophyll fluorescence, electric impedance and photosynthesis of the previous-year needles. Compared with the SNOW treatment, carbohydrate concentrations were lower in the FLOOD and NO SNOW treatments where the seedlings had almost died before the end of the experiment, presumably due to frost desiccation of aboveground parts during the winter treatments. The seedlings of the ICE treatment showed dead needles and stems only above the snow and ice cover. The results emphasize the importance of an insulating and protecting snow cover for small forest tree seedlings, and that future winters with changed snow patterns might affect the survival of tree seedlings and thus forest productivity. © The Author 2017.

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW). The specimens (~50% porosity) were subjected to various compressive strains (15, 30, 45%) and temperatures (room temperature, 35, 50, 70°C) in a nitrogen atmosphere (active purge) for 1 year. Compression set and load retention of the aged specimens were measured periodically during the study. Compression set increased with strain and temperature. After 1 year, specimens aged at room temperature, 35, and 50°C showed ~10% compression set (relative to the applied compressive deflection), while those aged at 70°C showed 20-40%. Due to the increasing compression set, load retention decreased with temperature, ranging from ~90% at room temperature to ~60-80% at 70°C. Long-term compression set and load retention at room temperature were predicted by applying time-temperature superposition (TTS). The predictions show compression set relative to the compressive deflection will be ~10-15% with ~70-90% load retention after 50 years at 15-45% strain, suggesting the material will continue to be mechanically functional. Comparison of the results to previously acquired data for cellular (M97*, M9760, M9763) and RTV (S5370) silicone foams suggests that the SE 1700 DIW porous specimens are on par with, or outperform, the legacy foams.

    Induction therapy in simultaneous heart-kidney transplantation (SHKT) is not well studied in the setting of contemporary maintenance immunosuppression consisting of tacrolimus (TAC), mycophenolic acid (MPA), and prednisone (PRED). We analyzed the Organ Procurement and Transplant Network registry from January 1, 2000, to March 3, 2015, for recipients of SHKT (N = 623) maintained on TAC/MPA/PRED at hospital discharge. The study cohort was further stratified into 3 groups by induction choice: induction (n = 232), rabbit anti-thymoglobulin (r-ATG; n = 204), and interleukin-2 receptor-α (n = 187) antagonists. Survival rates were estimated using the Kaplan-Meier estimator. Multivariable inverse probability weighted Cox proportional hazard regression models were used to assess hazard ratios associated with post-transplant mortality as the primary outcome. The study cohort was censored on March 4, 2016, to allow at least 1-year of follow-up. During the study period, the number of SHKTs increased nearly 5-fold. The Kaplan-Meier survival curve showed superior outcomes with r-ATG compared with no induction or interleukin-2 receptor-α induction. Compared with the no-induction group, an inverse probability weighted Cox proportional hazard model showed no independent association of induction therapy with the primary outcome. In sub-group analysis, r-ATG appeared to lower mortality in sensitized patients with panel reactive antibody of 10% or higher (hazard ratio, 0.19; 95% confidence interval, 0.05-0.71). r-ATG may provide a survival benefit in SHKT, especially in sensitized patients maintained on TAC/MPA/PRED at hospital discharge.

    Previous studies have found that depression predicts all-cause mortality in heart failure (HF), but little is known about its effect on long-term survival. This study examined the effects of depression on long-term survival in patients with HF. Patients hospitalized with HF (n = 662) at an urban academic medical center were enrolled in a prospective cohort study between January 1994 and July 1999. Depression was assessed on a structured interview during the index hospitalization and on quarterly interviews for 1 year after discharge. Patients were classified at index as having Diagnostic and Statistical Manual, Fourth Edition major depressive disorder (n = 131), minor depression (n = 106), or no depression (n = 425). Clinical data and the National Death Index were used to identify date of death or last known contact through December 19, 2014, up to 20 years after the index hospitalization. The main outcome was time from enrollment to death from any cause. A total of 617 (94.1%) patients died during the follow-up period. Major depressive disorder was associated with higher all-cause mortality compared with no depression (adjusted hazard ratio = 1.64, 95% confidence interval = 1.27-2.11, p = .0001). This association was stronger than that of any of the established predictors of mortality that were included in the fully adjusted model. Patients with persistent or worsening depressive symptoms during the year after discharge were at greatest risk for death. The association between minor depression and survival was not significant. Major depression is an independent risk factor for all-cause mortality in patients with HF. Its effect persists for many years after the diagnosis of depression.

    To compute the life expectancy of persons with traumatic brain injury (TBI) based on validated prognostic models from 2 cohorts, to compare mortality and life expectancy of persons with TBI with those of the U.S. general population, and to investigate trends toward improved survival over the last 2 decades. Survival analysis. Postdischarge from rehabilitation units and long-term follow-up at regional centers. Two cohorts of long-term survivors of TBI (N=12,481): the Traumatic Brain Injury Model Systems (TBIMS) cohort comprised 7365 persons who were admitted to a TBIMS facility with moderate to severe TBI and were assessed at ≥1 years postinjury, and the California Department of Developmental Services (CDDS) cohort comprised 5116 persons who sustained a TBI and received long-term services from the CDDS. Not applicable. Life expectancy. The estimates of age-, sex-, and disability-specific life expectancy of persons with TBI derived from the CDDS and TBIMS were similar. The estimates of age- and sex-specific life expectancy were lower than those of the U.S. general population. Mortality rates of persons with TBI were higher than those of the U.S. general population. Mortality rates did not improve and the standardized mortality ratio increased over the study period from 1988 to 2010. Life expectancy of persons with TBI is lower than that of the general population and depends on age, sex, and severity of disability. When compared, the survival outcomes in the TBIMS and CDDS cohorts are remarkably similar. Because there have been no marked trends in the last 20 years, the life expectancies presented in this article may remain valid in the future.

    -year survival for patients in this cohort was 52%, and the 1-year local control rate was 77%. The median (±standard error) overall survival was 13.2 ± 1.9 months. There was no difference in survival between patients with a single lesion and those with multiple lesions (p = 0.319) after controlling for age, sex, and histology of primary tumor. Patients with primary breast histology had the greatest overall median survival (22.9 ± 6.2 months); patients with colorectal cancer had the shortest overall median survival (5.3 ± 1.8 months). The most common cause of death in this series was systemic progression (79%). These results confirm that 1-year survival for patients with multiple intracranial metastases treated with resection followed by SRS to both the tumor bed and synchronous lesions is similar to established outcomes for patients with a single intracranial metastasis.

    To examine the influence of perinatal hypoxia-ischaemia (HI) or low Apgar scores on distortion product otoacoustic emissions (DPOAEs) in infants at 1 year and detect any postnatal changes. Eighty-eight term infants born with perinatal HI or low Apgar scores alone were recruited at 1 year of age. The ears with type A tympanogram (normal) were studied with DPOAEs at 10 frequencies between 0.5 kHz and 10 kHz. DPOAE pass rates were decreased at all frequencies 1-10 kHz, particularly 1 and 2 kHz in both infants born with HI and those with low Apgar scores (χ(2) = 3.80-15.09, P Apgar score. Compared with those recorded at 1 and 6 months, DPOAE pass rates at 1 year were increased slightly in infants born with HI, but showed no marked changes in those born with low Apgar scores. DPOAE pass rates, mainly at 1 and 2 kHz, were decreased at 1 year in infants born with perinatal HI and low Apgar scores, suggesting a relative poor cochlear function. Further studies are needed to ascertain the hearing acuity. © 2011 The Authors.

    Full Text Available Critical periods of atopic status formation in children of 0-1 years of age dictate the need in search and introduction to practice of effective allergy prevention methods. The aim of this study is to substantiate efficacy of using hypoallergenic beikost products on the basis of turkey or rabbit meat for prevention of atopic disease and polyvalent allergy development. The study participants are children over 6 months of age with compromised family allergology anamnesis and mild skin manifestation of allergy. The results have confirmed low sensitizing potential of the studied beikost products, good tolerability and efficacy of use for the prevention of atopic process development. The obtained results allow recommending the studied turkey or rabbit meat purees to the risk group children and children with allergy as primary/secondary allergy preventive means and within therapeutic diets.

    Magmatic systems show periodicity in productivity, magma chemistry and dynamics of volcanic eruptions. The timescales over which such parameters change are highly variable and ranges between several tens of millions of years down to few hundredths of thousands years. While magmatic activity appears modulated at various frequencies, the lifetime of single volcanic systems, the duration of emplacement of single plutons, or the timespan over which a given volcanic region is active, appear to last for distinct but characteristic periods of time. Hundredths of thousands of years is a typical number for the range of zircon crystallisation ages in the products of large eruptions or for the lifetime of single plutons, while activity in volcanic regions or the duration of emplacement of crustal batholiths appears to last up to about 10 Ma. Several mechanisms such as variable magma productivity in the mantle, delamination, thermal and mechanical maturation of the crust have been proposed to modulate magmatic activity. All these processes indeed contribute to modulate the periodicity of magmatic activity, but because certain timescales are recurrent, some fundamental processes must play a fundamental role in regulating the "tempo" of magmatism. Are transitions of behaviour finally the product of major changes in mantle dynamics or is the crust the plays the pivotal role in modulating periodic variations observed in magmatic systems? In this contribution I will provide an overview of existing data on periodicity of magmatic systems and use thermal modelling to show that periodic variations of magma chemistry and the physical properties of magmas are an inexorable consequence of the evolution of the thermal budget of magmatic systems. I hope to trigger discussion and collaborations between experts of geodynamics and magmatism to establish relationships between periodicity, mantle and crustal processes.

  20. Synchronization and survival of connected bacterial populations

    Migration plays a vital role in controlling population dynamics of species occupying distinct habitat patches. While local populations are vulnerable to extinction due to demographic or environmental stochasticity, migration from neighboring habitat patches can rescue these populations through colonization of uninhabited regions. However, a large migratory flux can synchronize the population dynamics in connected patches, thereby enhancing the risk of global extinction during periods of depression in population size. Here, we investigate this trade-off between local rescue and global extinction experimentally using laboratory populations of E. coli bacteria. Our model system consists of co-cultures of ampicillin resistant and chloramphenicol resistant strains that form a cross-protection mutualism and exhibit period-3 oscillations in the relative population density in the presence of both antibiotics. We quantify the onset of synchronization of oscillations in a pair of co-cultures connected by migration and demonstrate that period-3 oscillations can be disturbed for moderate rates of migration. These features are consistent with simulations of a mechanistic model of antibiotic deactivation in our system. The simulations further predict that the probability of survival of connected populations in high concentrations of antibiotics is maximized at intermediate migration rates. We verify this prediction experimentally and show that survival is enhanced through a combination of disturbance of period-3 oscillations and stochastic re-colonization events.

    The effect of seawater adaptation on the survival of coastally released post-smelt trout, Salmo trutta L., was investigated by release: (1) directly (with no adaptation); (2) after retention in net pens in the sea for 29-131 days (delayed release); (3) after feeding with a high salt diet (12...... survival rate. A longer adaptation period did not increase survival. On average, survival was increased by 36%. Survival was not increased by high-salt diets. Until attainment of the legal size for capture, survival was 9.6% higher on average, with extremes as low as 1.7% and as high as 38% in individual...

  2. OBESITY IN CANCER SURVIVAL

    Although obesity is a well known risk factor for several cancers, its role on cancer survival is poorly understood. We conducted a systematic literature review to assess the current evidence evaluating the impact of body adiposity on the prognosis of the three most common obesity-related cancers: prostate, colorectal, and breast. We included 33 studies of breast cancer, six studies of prostate cancer, and eight studies of colorectal cancer. We note that the evidence over-represents breast cancer survivorship research and is sparse for prostate and colorectal cancers. Overall, most studies support a relationship between body adiposity and site-specific mortality or cancer progression. However, most of the research was not specifically designed to study these outcomes and, therefore, several methodological issues should be considered before integrating their results to draw conclusions. Further research is urgently warranted to assess the long-term impact of obesity among the growing population of cancer survivors. PMID:22540252

    Only few Candida species, e.g., Candida albicans, Candida glabrata, Candida dubliniensis, and Candida parapsilosis, are successful colonizers of a human host. Under certain circumstances these species can cause infections ranging from superficial to life-threatening disseminated candidiasis. The success of C. albicans, the most prevalent and best studied Candida species, as both commensal and human pathogen depends on its genetic, biochemical, and morphological flexibility which facilitates adaptation to a wide range of host niches. In addition, formation of biofilms provides additional protection from adverse environmental conditions. Furthermore, in many host niches Candida cells coexist with members of the human microbiome. The resulting fungal-bacterial interactions have a major influence on the success of C. albicans as commensal and also influence disease development and outcome. In this chapter, we review the current knowledge of important survival strategies of Candida spp., focusing on fundamental fitness and virulence traits of C. albicans. Copyright © 2015 Elsevier Inc.

    We examined the deaths of 28,169 adult Chinese-Americans, and 412,632 randomly selected, matched controls coded "white" on the death certificate. Chinese-Americans, but not whites, die significantly earlier than normal (1.3-4.9 yr) if they have a combination of disease and birthyear which Chinese astrology and medicine consider ill-fated. The more strongly a group is attached to Chinese traditions, the more years of life are lost. Our results hold for nearly all major causes of death studied. The reduction in survival cannot be completely explained by a change in the behaviour of the Chinese patient, doctor, or death-registrar, but seems to result at least partly from psychosomatic processes.

    This study was undertaken to estimate the survival of patients with dementia and to evaluate change in prognosis over time. Individuals attending a day care center for dementia in a 10 year period were followed until December 1st 1996 or until death. These individuals are quite repres notentative for demented patients living in this area. Of 180 individuals, 167 had either been diagnosed with Alzheimer's disease or multi infarct dementia. Ninety seven had died during follow up. Crude survival as well as relative survival was calculated with regards to the onset of symptoms of dementia. Patients with Alzheimer's disease seemed to live 40% shorter than age and gender matched individuals in the societ
