Short-term prospective memory deficits in chronic back pain patients.

2007-01-01

Chronic pain, particularly low back pain, is widespread. Although a great deal is known about the impact that this has on quality of life and physical activity, relatively little has been established regarding the more cognitive effects of pain. This study aims to find out whether individuals with chronic pain experience memory deficits in prospective memory (PM), the process of remembering to do things at some future point in time. Examples of PM include remembering to keep an appointment, such as a visit to a clinic, or to perform a particular task, such as paying a bill on time. The PM of 50 participants with chronic pain was compared with 50 pain-free participants. Each participant completed the Prospective Memory Questionnaire, which assesses three aspects of prospective memory (short-term habitual, long-term episodic, and internally cued), and records the use of strategies to aid remembering. In comparison to those not in pain, participants with chronic pain had significantly impaired short-term prospective memory, an effect which was evident even after co-varying use of analgesics and other drugs. These findings provide new insights into prospective memory dysfunction in people with chronic pain. Possible mechanisms for this dysfunction are discussed and suggestions for future research given.

A prospective study of severe hypoglycemia and long-term spatial memory in children with type 1 diabetes.

PubMed

Hershey, Tamara; Lillie, Rema; Sadler, Michelle; White, Neil H

2004-06-01

In a previous retrospective study, severe hypoglycemia (SH) was associated with decreased long-term spatial memory in children with type 1 diabetes mellitus (T1DM). In this study, we tested the hypothesis that prospectively ascertained SH would also be associated with decreased spatial long-term memory over time. Children with T1DM (n = 42) and sibling controls (n = 25) performed a spatial delayed response (SDR) task with short and long delays and other neuropsychological tests at baseline and after 15 months of monitoring. Extreme glycemic events and other medical complications were recorded prospectively during follow-up. Fourteen T1DM children experienced at least one episode of SH during the follow-up period (range = 1-5). After controlling for long-delay SDR performance at baseline, age, gender, and age of onset, the presence of SH during the prospective period was statistically associated with decreased long-delay SDR performance at follow-up (semipartial r = -0.38, p = 0.017). This relationship was not seen with short-delay SDR or with verbal or object memory, attention, or motor speed. These results, together with previously reported data, support the hypothesis that SH has specific, negative effects on spatial memory skills in T1DM children.

Facework and uncertain reasoning in health communication.

PubMed

Pighin, Stefania; Bonnefon, Jean-François

2011-11-01

Health care professionals often need to convey good and bad prospects to patients, and these news can be qualified by various uncertainty terms. Based on a sociolinguistic analysis of the way these uncertainty terms are used, we predicted that they would be interpreted differently by patients as a function of whether they qualified good news or bad news. Two studies investigating causal inferences were conducted among a sample of French university students (Study 1, N=50), and among a sample of Italian pregnant women (Study 2, N=532). Participants felt greater confidence in the conclusions they derived when the news were bad, as compared to the conclusions they derived when the news were good. The findings have implications for health care professionals who communicate good and bad prospects to patients, and who need to qualify the certainty of these prospects. Professionals should be aware that when the news are bad, any hedging term such as "possible" can be misunderstood as an attempt to sugar-coat the pill, and that this misinterpretation can lead patient to inferences that are not shared by the professional.

Lacking evidence for performance of implants used for proximal femoral fractures - A systematic review.

PubMed

Nyholm, Anne Marie; Palm, Henrik; Malchau, Henrik; Troelsen, Anders; Gromov, Kirill

2016-03-01

Evaluation of the long-term performance of implants used in trauma surgery relies on post-marked clinical studies since no registry based implant assessment exists. The purpose of this study was to evaluate the evidence of performance of implants currently used for treating proximal femoral fractures (PFF) in Denmark. PubMed was searched for clinical studies on primary PFF with follow-up ≥12 months, reporting implant-related failure and evaluating one of following: DHS, CHS, HipLoc, Gamma3, IMHS, InterTan, PFN, PFNA or PTN. English language and publication date after 1st of January 1990. All studies were evidence level II or III. 30 publications for SHS were found: 13 of CHS, 15 of DHS and 2 of HipLoc. In total CHS was evaluated in 1110 patients (900 prospectively), DHS in 2486 (567 prospectively) and HipLoc in 251 (all prospectively). Fifty-four publications for nails were found: 13 of Gamma3, 7 of IMHS, 5 of InterTan, 10 of PFN, 24 of PFNA and 0 of PTN. In total Gamma3 was evaluated in 1088 patients (829 prospectively), IMHS in 1543 (210 prospectively), InterTan in 595 (585 prospectively), PFN in 716 (557 prospectively), PFNA in 1762 (1018 prospectively) and PTN in 0. The clinical evidence behind the current implants used for proximal femoral fractures is weak considering the number of implants used worldwide. Sporadic evaluation is not sufficient to identify long term problems. A systematic post market surveillance of implants used for fracture treatment, preferable by a national register, is necessary in the future. Copyright © 2016 Elsevier Ltd. All rights reserved.

A qualitative study to explore Prospect theory and message framing and diet and cancer prevention-related issues among African American adolescents

PubMed Central

Satia, Jessie A.; Barlow, Jameta; Armstrong-Brown, Janelle; Watters, Joanne L.

2010-01-01

Aims To develop and test cancer prevention messages based on Prospect theory on motivation to improve dietary intake in African American adolescents, and to explore other salient factors that may inform dietary intervention design and implementation in this population. Methods Semi-structured in-person qualitative interviews were conducted with 13 African-American male and female adolescents, 12-16 years, in North Carolina. Prospect theory and message framing were used to guide the design of the four sets of diet-related messages related to cancer prevention: short-term gain-, long-term gain-, short-term loss-, and long-term loss-framed messages. Data were also collected on demographic, behavioral, and psychological factors; usual health behaviors; and preferences for intervention delivery. Results The majority of respondents found the gain-framed, short-term messages most salient for both fruits/vegetables (8 (61.5%)), and fat consumption (7 (53.8%)). For fat consumption only, 2 (15.4%) found the loss-framed, short-term messages pertinent; none found the loss-framed, long-term messages relevant for either dietary variable. All indicated interest in participating in a dietary intervention/education program; most preferred the Internet as a channel for intervention delivery. Participants expressed diverse views regarding knowledge, attitudes, and beliefs regarding healthy eating. Conclusions Researchers conducting dietary interventions and education initiatives and medical professionals who counsel African American adolescents should consider using Prospect Theory as a theoretical framework, should focus on gain-framed short-term messages regarding cancer prevention, and should employ the Internet for data collection and intervention and information delivery.

NHS Stop Smoking Services (SSSs) provide free at the point of use treatment for smokers who would like to stop. Since their inception in 1999 they have evolved to offer a variety of support options. Given the changes that have happened in the provision of services and the ongoing need for evidence on effectiveness, the Evaluating Long-term Outcomes for NHS Stop Smoking Services (ELONS) study was commissioned. The main aim of the study was to explore the factors that determine longer-term abstinence from smoking following intervention by SSSs. There were also a number of additional objectives. The ELONS study was an observational study with two main stages: secondary analysis of routine data collected by SSSs and a prospective cohort study of service clients. The prospective study had additional elements on client satisfaction, well-being and longer-term nicotine replacement therapy (NRT) use. The setting for the study was SSSs in England. For the secondary analysis, routine data from 49 services were obtained. For the prospective study and its added elements, nine services were involved. The target population was clients of these services. There were 202,804 cases included in secondary analysis and 3075 in the prospective study. A combination of behavioural support and stop smoking medication delivered by SSS practitioners. Abstinence from smoking at 4 and 52 weeks after setting a quit date, validated by a carbon monoxide (CO) breath test. Just over 4 in 10 smokers (41%) recruited to the prospective study were biochemically validated as abstinent from smoking at 4 weeks (which was broadly comparable with findings from the secondary analysis of routine service data, where self-reported 4-week quit rates were 48%, falling to 34% when biochemical validation had occurred). At the 1-year follow-up, 8% of prospective study clients were CO validated as abstinent from smoking. Clients who received specialist one-to-one behavioural support were twice as likely to have remained abstinent than those who were seen by a general practitioner (GP) practice and pharmacy providers [odds ratio (OR) 2.3, 95% confidence interval (CI) 1.2 to 4.6]. Clients who received group behavioural support (either closed or rolling groups) were three times more likely to stop smoking than those who were seen by a GP practice or pharmacy providers (OR 3.4, 95% CI 1.7 to 6.7). Satisfaction with services was high and well-being at baseline was found to be a predictor of abstinence from smoking at longer-term follow-up. Continued use of NRT at 1 year was rare, but no evidence of harm from longer-term use was identified from the data collected. Stop Smoking Services in England are effective in helping smokers to move away from tobacco use. Using the 52-week CO-validated quit rate of 8% found in this study, we estimate that in the year 2012-13 the services supported 36,249 clients to become non-smokers for the remainder of their lives. This is a substantial figure and provides one indicator of the ongoing value of the treatment that the services provide. The study raises a number of issues for future research including (1) examining the role of electronic cigarettes (e-cigarettes) in smoking cessation for service clients [this study did not look at e-cigarette use (except briefly in the longer-term NRT study) but this is a priority for future studies]; (2) more detailed comparisons of rolling groups with other forms of behavioural support; (3) further exploration of the role of practitioner knowledge, skills and use of effective behaviour change techniques in supporting service clients to stop smoking; (4) surveillance of the impact of structural and funding changes on the future development and sustainability of SSSs; and (5) more detailed analysis of well-being over time between those who successfully stop smoking and those who relapse. Further research on longer-term use of non-combustible nicotine products that measures a wider array of biomarkers of smoking-related harm such as lung function tests or carcinogen metabolites. The National Institute for Health Research Health Technology Assessment programme. The UK Centre for Tobacco and Alcohol Studies provided funding for the longer-term NRT study.

Laparoscopic Complete Mesocolic Excision versus Open Complete Mesocolic Excision for Transverse Colon Cancer: Long-Term Survival Results of a Prospective Single Centre Non-Randomized Study.

Storli, Kristian Eeg; Eide, Geir Egil

2016-01-01

Laparoscopic complete mesocolic excision (CME) used in the treatment of transverse colon cancer has been questioned on the basis of the technical challenges. The aim of this study was to evaluate the medium- and long-term clinical and survival outcomes after laparoscopic and open CME for transverse colon cancer and to compare the 2 approaches. This study was a retrospective non-randomized study of patients with prospectively registered data on open and laparoscopic CME for transverse colon cancer tumour-node-metastasis stages I-III operated on between 2007 and 2014. This was a single-centre study in a community teaching hospital. A total of 56 patients with transverse colon cancer were included, excluding those with tumours in the colonic flexures. The outcome aims were 4-year time to recurrence (TTR) and cancer-specific survival (CSS). Morbidity was also measured. The 4-year TTR was 93.9% in the laparoscopic group and 91.3% in the open group (p = 0.71). The 4-year CSS was 97.0% in the laparoscopic group and 91.3% in the open group (p = 0.42). This was a prospective single-institution study with a small sample size. Results of the study suggest that the laparoscopic CME approach might be the preferred approach for transverse colon cancer, especially regarding its benefits in terms of short-term morbidity, length of stay and oncological outcome. © 2016 S.

2018-05-15

Patients with amnestic Mild Cognitive Impairment (aMCI), usually considered an early stage of Alzheimer's disease, have deficits not only in retrospective memory (RM), that is, recalling of past events, words or people, but also on prospective memory (PM), the cognitive ability of remembering to execute delayed intentions in the future. This study investigated whether patients with aMCI refer more PM complaints as compared with RM complaints, and whether this might depend upon short-term vs long-term items or time-based vs event-based tasks. Patients with aMCI (n = 178) and healthy controls (n = 160) underwent the Prospective and Retrospective Memory Questionnaire (PRMQ), a 16-item instrument to appraise differences between PM and RM complaints, as well as a general mental state examination, a subjective memory complaints questionnaire, objective memory tests, and assessment of depressive symptoms and activities of daily living. Patients with aMCI reported more memory complaints evaluated with the PRMQ (total score = 44.3 ± 10.8) as compared with controls (36.7 ± 9.8, P < 0.001). Using a mixed effect repeated-measures analysis of covariance (ANCOVA) showed that participants generally referred more retrospective than prospective memory complaints. Patients with aMCI had significantly more complaints on short-term memory as compared with long-term memory, and more complaints in time-based (auto-initiated) as compared with event-based tasks, than healthy controls. Patients with aMCI reported significantly more difficulties on short-term memory, presumably reflecting internal temporal lobe pathology typical of Alzheimer's disease, and more complaints on time-based tasks, which are cognitively very demanding, but did not seem particularly troubled regarding prospective memory.

2011-02-01

There is continuing public and scientific interest in the possibility that exposure to radiofrequency (RF) electromagnetic fields (EMF) from mobile telephones or other wireless devices and applications might increase the risk of certain cancers or other diseases. The interest is amplified by the rapid world-wide penetration of such technologies. The evidence from epidemiological studies published to date have not been consistent and, in particular, further studies are required to identify whether longer term (well beyond 10 years) RF exposure might pose some health risk. The "Cosmos" study described here is a large prospective cohort study of mobile telephone users (ongoing recruitment of 250,000 men and women aged 18+ years in five European countries - Denmark, Finland, Sweden, The Netherlands, UK) who will be followed up for 25+ years. Information on mobile telephone use is collected prospectively through questionnaires and objective traffic data from network operators. Associations with disease risks will be studied by linking cohort members to existing disease registries, while changes in symptoms such as headache and sleep quality and of general well-being are assessed by baseline and follow-up questionnaires. A prospective cohort study conducted with appropriate diligence and a sufficient sample size, overcomes many of the shortcomings of previous studies. Its major advantages are exposure assessment prior to the diagnosis of disease, the prospective collection of objective exposure information, long-term follow-up of multiple health outcomes, and the flexibility to investigate future changes in technologies or new research questions.

There is a dearth of knowledge regarding factors that may motivate African American adolescents to consume healthier diets. To develop and test cancer prevention messages based on Prospect Theory on motivation to improve dietary intake in African American adolescents and to explore other salient factors that may inform dietary intervention design and implementation in this population. Semistructured in-person qualitative interviews were conducted with 13 African American male and female adolescents, aged 12 to 16 years, in North Carolina. Prospect Theory and message framing were used to guide the design of the 4 sets of diet-related messages related to cancer prevention: short-term, gain-framed; long-term, gain-framed; short-term, loss-framed; and long-term, loss-framed messages. Data were also collected on demographic, behavioral, and psychological factors; usual health behaviors; and preferences for intervention delivery. Most respondents found the gain-framed, short-term messages most salient for both fruits/vegetables (8 [61.5%]) and fat consumption (7 [53.8%]). For fat consumption only, 2 (15.4%) found the loss-framed, short-term messages pertinent; none found the loss-framed, long-term messages relevant for either dietary variable. All indicated interest in participating in a dietary intervention/education program; most preferred the Internet as a channel for intervention delivery. Participants expressed diverse views regarding knowledge, attitudes, and beliefs regarding healthy eating. The gain-framed, short-term messages were most salient for motivating the majority of respondents to consume a healthy diet and most expressed a strong interest in participating in programs about diet and nutrition, with the Internet as the preferred communication channel. Researchers conducting dietary interventions and education initiatives and medical professionals who counsel African American adolescents should consider using Prospect Theory as a theoretical framework, should focus on gain-framed, short-term messages regarding cancer prevention, and should use the Internet for data collection and intervention and information delivery.

Ursodiol in patients with parenteral nutrition-associated cholestasis.

PubMed

San Luis, Valerie A; Btaiche, Imad F

2007-11-01

To review the role of ursodeoxycholic acid (ursodiol) in treating parenteral nutrition-associated cholestasis (PNAC). A MEDLINE (1950-May 2007) search was performed using the key terms parenteral nutrition, cholestasis, ursodeoxycholic acid, and ursodiol. All English-language articles that evaluated the safety and efficacy of ursodiol for PNAC were included in this review. The benefits of exogenous ursodiol administration in the treatment of cholestasis can be explained by its alteration of effects on bile composition and flow and provision of cytoprotective, membrane stabilizing, and immunomodulatory effects. Two animal studies, 2 case reports, and 6 human studies (2 prospective and 3 retrospective pediatric studies, 1 adult prospective study) evaluated the efficacy of ursodiol in patients with PNAC. Ursodiol 10-30 mg/kg/day in children and 10-15 mg/kg/day in adults administered in 2-3 doses improved the biochemical and clinical signs and symptoms of PNAC. However, short-term improvement in biochemical parameters may not necessarily predict the outcome of PNAC patients. At recommended doses, ursodiol may not be effective in patients with short bowel syndrome or in those with resected terminal ileum because of reduced ursodiol absorption. Studies supporting the efficacy of ursodiol in treatment of PNAC are limited by small sample size, absence of randomization and controls, short duration, and lack of accountancy to confounding variables. Large, prospective, randomized, placebo-controlled, long-term follow-up studies evaluating the efficacy and optimal dosing and duration of ursodiol therapy for PNAC are not yet available. Ursodiol may improve the biochemical signs and clinical symptoms of PNAC. However, optimal dosing, timing, duration of therapy, and long-term effects on PNAC outcome and prognosis require further studies.

Prospective associations between prosocial behavior and social dominance in early childhood: are sharers the best leaders?

Ostrov, Jamie M; Guzzo, Jamie L

2015-01-01

A short-term longitudinal study during early childhood (N = 96; M = 42.80; SD = 7.57) investigated the concurrent and prospective association between prosocial behavior and social dominance. Time-intensive school-based focal child sampling with continuous recording observations of prosocial behavior to peers were conducted and teacher-reports of social dominance were collected. The study documents significant prospective links between prosocial behavior to peers and increases in social dominance over time. Social dominance was not associated with changes in prosocial behavior. The findings extend past empirical work in early childhood and future directions are discussed.

Coffee, tea, and cocoa and risk of stroke.

PubMed

Larsson, Susanna C

2014-01-01

Current evidence from experimental studies in animals and humans along with findings from prospective studies indicates beneficial effects of green and black tea as well as chocolate on cardiovascular health, and that tea and chocolate consumption may reduce the risk of stroke. The strongest evidence exists for beneficial effects of tea and cocoa on endothelial function, total and LDL cholesterol (tea only), and insulin sensitivity (cocoa only). The majority of prospective studies have reported a weak inverse association between moderate consumption of coffee and risk of stroke. However, there are yet no clear biological mechanisms whereby coffee might provide cardiovascular health benefits. Awaiting the results from further long-term RCTs and prospective studies, moderate consumption of filtered coffee, tea, and dark chocolate seems prudent.

Study protocol: The Improving Care of Acute Lung Injury Patients (ICAP) study

Introduction The short-term mortality benefit of lower tidal volume ventilation (LTVV) for patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) has been demonstrated in a large, multi-center randomized trial. However, the impact of LTVV and other critical care therapies on the longer-term outcomes of ALI/ARDS survivors remains uncertain. The Improving Care of ALI Patients (ICAP) study is a multi-site, prospective cohort study that aims to evaluate the longer-term outcomes of ALI/ARDS survivors with a particular focus on the effect of LTVV and other critical care therapies. Methods Consecutive mechanically ventilated ALI/ARDS patients from 11 intensive care units (ICUs) at four hospitals in the city of Baltimore, MD, USA, will be enrolled in a prospective cohort study. Exposures (patient-based, clinical management, and ICU organizational) will be comprehensively collected both at baseline and throughout patients' ICU stay. Outcomes, including mortality, organ impairment, functional status, and quality of life, will be assessed with the use of standardized surveys and testing at 3, 6, 12, and 24 months after ALI/ARDS diagnosis. A multi-faceted retention strategy will be used to minimize participant loss to follow-up. Results On the basis of the historical incidence of ALI/ARDS at the study sites, we expect to enroll 520 patients over two years. This projected sample size is more than double that of any published study of long-term outcomes in ALI/ARDS survivors, providing 86% power to detect a relative mortality hazard of 0.70 in patients receiving higher versus lower exposure to LTVV. The projected sample size also provides sufficient power to evaluate the association between a variety of other exposure and outcome variables, including quality of life. Conclusion The ICAP study is a novel, prospective cohort study that will build on previous critical care research to improve our understanding of the longer-term impact of ALI/ARDS, LTVV and other aspects of critical care management. Given the paucity of information about the impact of interventions on long-term outcomes for survivors of critical illness, this study can provide important information to inform clinical practice.

This study covers phase IV of a prospective clinical long-term study. Objective of this clinical investigation was to analyze the effects of a long-term prevention program on dental and oral health of teenagers at the age of 13 to 14 years. The entire study was subdivided into four phases. Phase I comprised an individual preventive care during pregnancy ("primary-primary prevention"); phase II assessed mothers and their young children until the age of 3 years ("primary prevention"); and in phase III, mothers and children at the age of 6 years were investigated. In phase IV of the study, the oral health of 13- to 14-year-old teenagers was examined (13.4 +/- 0.5 years; n = 29). All phases consisted of an examination, education about oral health care, and treatment based on the concept of an early oral health care promotion. The control group consisted of randomly selected adolescents at the same age (n = 30). The following clinical parameters were assessed: decayed/missing/filled teeth (DMF-T)/decayed, missing, and filled surface teeth index, hygiene index, papilla bleeding index, Periodontal Screening Index, and Streptococcus mutans/Lactobacillus concentration in saliva. The teenagers of the "prevention" group of phase IV of our prospective study revealed a share of 89.7% caries-free dentitions (65.5% sound; 24.2% caries-free with fillings). Mean DMF-T was 0.55 +/- 1.0. The control group showed a significantly higher mean DMF-T of 1.5 +/- 1.5 (p < 0.05) and revealed 56.7% of caries-free dentitions (30% sound, 26.7% caries-free with restorations). Our data clearly document that an early oral health care promotion starting during pregnancy may cause a sustained and long-term improvement of the oral health of children.

2016-01-01

Background Fetomaternal hemorrhage (FMH) is a poorly understood condition in which fetal erythrocytes transfer to the maternal circulation via a faulty placental barrier. Little is known about the true incidence, epidemiology, or pathophysiology of FMH in the general pregnant population as existing studies are based on retrospective cohorts and manifest diagnosis and selection bias. Objective To evaluate the practicability of a prospective study of fetomaternal hemorrhage in the general population based on antepartum maternal blood testing and neonatal anemia. Study Design Prospective cohort study. Result Nineteen pregnant women were enrolled prior to the term delivery of twenty well infants. Five neonates were unexpectedly anemic on first postnatal testing. Antenatal maternal blood samples associated with 2 of 5 anemic newborns had positive Kleihauer-Betke testing while no newborn with a normal postnatal blood count had an associated abnormal Kleihauer-Betke test. Conclusion Clinically significant FMH may be more common than previously thought. Prospective epidemiological study of FMH is feasible. PMID:26765555

Objectives Few studies examine the influence of early predictors of work absence beyond 12 months following injury or the time-dependent relative importance of these factors. This study aimed to identify the most important sociodemographic, occupational, health, lifestyle and injury predictors of work absence at 12 and 24 months following injury and to examine changes in the relative importance of these over time. Design Prospective cohort study. Setting The Prospective Outcomes of Injury Study, New Zealand. Participants 2626 injured New Zealand workers aged 18–64 years were identified from the Prospective Outcomes of Injury Study recruited form New Zealand’s monopoly injury compensation provider injury claims register: 2092 completed the 12-month interview (80% follow-up) and 2082 completed the 24-month interview (79% follow-up). Primary and secondary outcomes measures The primary outcomes of interest was absence from work at the time of the 12-month and 24-month follow-up interviews. Results Using modified Poisson regression to estimate relative risks, important groups of workers were identified at increased risk of work absence at both 12 and 24 months: males, low-income workers, trade/manual workers, temporary employees, those reporting two or more comorbidities and those experiencing a work-related injury. Important factors unique to predicting work absence at 12 months included financial insecurity, fixed-term employment and long weekly hours worked; unique factors at 24 months included job dissatisfaction, long weekly days worked, a prior injury and sustaining an injury that was perceived to be a threat to life. Conclusions Important early predictors of work absence at 12 or 24 months following injury are multidimensional and have a time dependent pattern. A consistent set of predictors was, however, present at both time periods that are prime for early intervention. Understanding the multidimensional, time-dependent patterns of early predictors of long-term disability is important to optimally target timely interventions to prevent long-term work disability.

Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P < 0.0001) lower in the lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.

Nonsurgical Outpatient Therapies for the Management of Female Stress Urinary Incontinence: Long-Term Effectiveness and Durability

PubMed Central

Davila, G. Willy

2011-01-01

Objective. To evaluate long-term effectiveness and safety of conservative and minimally invasive outpatient treatments for female stress urinary incontinence (SUI) through a review of the literature. Methods. PubMed was searched for reports on prospective clinical trials with at least 12-month follow-up of minimally invasive treatments, pelvic floor rehabilitation, or pharmacotherapy in women with SUI. Each report was examined for long-term rates of effectiveness and safety. Results. Thirty-two clinical trial reports were included. Prospective long-term studies of pelvic floor rehabilitation were limited but indicated significant improvements with treatment adherence for at least 12 months. Poor initial tolerability with duloxetine resulted in substantial discontinuation. Most patients receiving transurethral radiofrequency collagen denaturation or urethral bulking agents reported significant long-term improvements, generally good tolerability, and safety. Conclusions. Conservative therapy is an appropriate initial approach for female SUI, but if therapy fails, radiofrequency collagen denaturation or bulking agents may be an attractive intermediate management step or alternative to surgery.

Neuroimaging evidence suggests that ecstasy-related reductions in SERT densities relate more closely to the number of tablets typically consumed per session rather than estimated total lifetime use. To better understand the basis of drug related deficits in prospective memory (p.m.) we explored the association between p.m. and average long-term typical dose and long-term frequency of use. Study 1: Sixty-five ecstasy/polydrug users and 85 nonecstasy users completed an event-based, a short-term and a long-term time-based p.m. task. Study 2: Study 1 data were merged with outcomes on the same p.m. measures from a previous study creating a combined sample of 103 ecstasy/polydrug users, 38 cannabis-only users, and 65 nonusers of illicit drugs. Study 1: Ecstasy/polydrug users had significant impairments on all p.m. outcomes compared with nonecstasy users. Study 2: Ecstasy/polydrug users were impaired in event-based p.m. compared with both other groups and in long-term time-based p.m. compared with nonillicit drug users. Both drug using groups did worse on the short-term time-based p.m. task compared with nonusers. Higher long-term average typical dose of ecstasy was associated with poorer performance on the event and short-term time-based p.m. tasks and accounted for unique variance in the two p.m. measures over and above the variance associated with cannabis and cocaine use. The typical ecstasy dose consumed in a single session is an important predictor of p.m. impairments with higher doses reflecting increasing tolerance giving rise to greater p.m. impairment.

Long-term results of a non-ramdomized prospective mono-centre study of 1000 laparoscopic totally extraperitoneal hernia repairs.

2008-01-01

Information concerning short-term results for laparoscopic extraperitoneal hernia repair is available, but long-term results remain poorly documented. The purpose of this non-randomized prospective study was to evaluate recurrence and chronic pain after hernia repair over a period longer than 10 years. From 1995 to 2004, all patients aged 30 years or more, manifesting with inguinal hernia, were included in our study. Patients aged 20 to 30 years presenting with bilateral hernia, recurrent hernia, or who were heavy workers were also included. Patients who had pelvic irradiation, strangulated hernia, prostatic cancer resection, or a contra-indication to general anaesthesia were excluded. Of 1096 hernia repairs performed, 248 patients were excluded and underwent open repair and 848 patients (77.4%) were included in our prospective study, which corresponded to 1000 laparoscopic hernia repairs. The sex ratio (male : female) was 5:8, and the average age was 56 years. Seven hundred and fifty-three hernias (75.3%) were first repairs, 247 (24.7%) were recurrent hernias, and 161 were bilateral hernias. There were no mortalities. The conversion rate was 1.1%, and the global postoperative morbidity rate was 10.3%. Average follow-up was 39 months in 92.2% of the patients. Hernia recurrence rate was 1.5%. Chronic pain occurred in 2.9%. During this follow-up, 22 contra-lateral hernias appeared in those patients who initially had unilateral hernia repair (3.2%). All of these contra-lateral hernias could be successfully treated using a laparoscopic total extraperitoneal approach. The long-term results of this study demonstrate that preperitoneal laparoscopic hernia repair is a safe technique with a very low recurrence rate and low prevalence of chronic pain.

Objective: To investigate prospective, population-based long-term outcomes concerning seizures and antiepileptic drug (AED) treatment after resective epilepsy surgery in Sweden. Methods: Ten- and 5-year follow-ups were performed in 2005 to 2007 for 278/327 patients after resective epilepsy surgery from 1995 to 1997 and 2000 to 2002, respectively. All patients had been prospectively followed in the Swedish National Epilepsy Surgery Register. Ninety-three patients, who were presurgically evaluated but not operated, served as controls. Results: In the long term (mean 7.6 years), 62% of operated adults and 50% of operated children were seizure-free, compared to 14% of nonoperated adults (p < 0.001) and 38% of nonoperated children (not significant). Forty-one percent of operated adults and 44% of operated children had sustained seizure freedom since surgery, compared to none of the controls (p < 0.0005). Multivariate analysis identified ≥30 seizures/month at baseline and long epilepsy duration as negative predictors and positive MRI to be a positive predictor of long-term seizure-free outcome. Ten years after surgery, 86% of seizure-free children and 43% of seizure-free adults had stopped AEDs in the surgery groups compared to none of the controls (p < 0.0005). Conclusions: This population-based, prospective study shows good long-term seizure outcomes after resective epilepsy surgery. The majority of the patients who are seizure-free after 5 and 10 years have sustained seizure freedom since surgery. Many patients who gain seizure freedom can successfully discontinue AEDs, more often children than adults. Classification of evidence: This study provides Class III evidence that more patients are seizure-free and have stopped AED treatment in the long term after resective epilepsy surgery than nonoperated epilepsy patients.

This study examined the association of work functioning impairment as measured by work functioning impairment scale (WFun) and subsequent sick leave. A prospective cohort study was conducted at a manufacturer in Japan, and 1263 employees participated. Information on sick leave was gathered during an 18-month follow-up period. The hazard ratios (HRs) of long-term sick leave were substantially increased for those with a WFun score greater than 25 (HR = 3.99, P = 0.003). The incidence rate ratios (IRRs) of days of short-term absence gradually increased as scores of WFun increased (IRR = 1.18, P < 0.001 in the subjects with WFun of over 25 comparing with those with WFun of 14 or less). Assessing work functioning impairment is a useful way of classifying risk for future sick leave among employees.

Meat, fish, poultry and egg consumption in relation to risk of pancreatic cancer: a prospective study.

2006-06-01

High meat consumption has been associated with increased risk of pancreatic cancer in several, although not all, case-control studies. However, prospective data on this relationship are sparse, and the results have been inconsistent. We prospectively evaluated meat, fish, poultry, and egg consumption in relation to pancreatic cancer incidence in a population-based cohort of 61,433 Swedish women. Diet was assessed with a food-frequency questionnaire at baseline (1987-1990) and again in 1997. Pancreatic cancers were ascertained through linkage to the Swedish Cancer Register. Cox proportional hazards models were used to estimate multivariate hazard ratios with 95% confidence intervals (CI). During the 941,218 person-years of follow-up, from 1987 through 2004, 172 incident cases of pancreatic cancer were diagnosed. Long-term red meat consumption (using data from both dietary questionnaires) was positively associated with risk of pancreatic cancer (p-trend = 0.01), whereas long-term poultry consumption was inversely (p-trend = 0.04) associated with risk. The multivariate hazard ratios for the highest versus the lowest category of consumption were 1.73 (95% CI = 0.99-2.98) for red meat and 0.44 (95% CI = 0.20-0.97) for poultry. There were no significant associations with processed meat, fish or egg consumption. Findings from this prospective study suggest that substituting poultry for red meat might reduce the risk of pancreatic cancer.

Good mathematical literacy skills will hopefully help maximize the tasks and role of the prospective teacher in activities. Mathematical literacy focus on students' ability to analyze, justify, and communicate ideas effectively, formulate, solve and interpret mathematical problems in a variety of forms and situations. The purpose of this study is to describe the mathematical literacy skills of the prospective teacher in term of gender differences. This research used a qualitative approach with a case study. Subjects of this study were taken from two male students and two female students of the mathematics education prospective teacher who have followed Community Service Program (CSP) in literacy. Data were collected through methods think a loud and interviews. Four prospective teachers were asked to fill mathematical literacy test and video taken during solving this test. Students are required to convey loud what he was thinking when solving problems. After students get the solution, researchers grouped the students' answers and results think aloud. Furthermore, the data are grouped and analyzed according to indicators of mathematical literacy skills. Male students have good of each indicator in mathematical literacy skills (the first indicator to the sixth indicator). Female students have good of mathematical literacy skills (the first indicator, the second indicator, the third indicator, the fourth indicator and the sixth indicator), except for the fifth indicators that are enough.

Academic decision making and prospect theory.

Two studies are reported that investigate the applicability of prospect theory to college students' academic decision making. Exp. 1 failed to provide support for the risk-seeking portion of the fourfold pattern predicted by prospect theory but did find the greater weighting of losses over gains. Using a more sensitive dependent measure, in Exp. 2 the results of the first experiment were replicated in terms of the gain-loss effect and also found some support for the fourfold pattern in the interaction between probabilities and gain versus loss. The greatest risk-seeking was found in the high probability loss condition.

In laparoscopic colorectal surgery, extraction site laparotomy can be avoided by natural orifice specimen extraction (NOSE) resulting in less postoperative pain, shorter length of stay, and less morbidity such as wound complications. To date, short-term outcome of a large prospective cohort of patients has not been studied. The aim of this prospective cohort study was to assess short-term outcome of laparoscopic left-sided NOSE-colectomy. Prospectively collected data of patients who had undergone elective laparoscopic NOSE-colectomy between July 2009 and December 2013 were analyzed retrospectively. Primary endpoint was short-term morbidity. A total of 110 patients were included in this study. Median age was 38 years (IQR: 32-56), median BMI was 23 kg/m(2) (IQR: 21-25), and 88% of the patients were female. Sixty-three patients (57%) underwent resection for endometriosis, 29 patients (26%) for diverticular disease, 16 patients (15%) for a tumor, and 2 patients for other indications. Median operating time was 85 min (IQR: 70-100) and median length of the extracted specimen was 20 cm (IQR: 16-25). Overall, 14 patients had a postoperative complication (13%), of which 9 were Clavien-Dindo grade 1 or 2 (8%). Four patients (3.6%) had an intraluminal bleeding from the anastomosis, which was treated endoscopically. There was 1 anastomotic leak (1%), treated by emergency laparotomy and creation of a new colorectal anastomosis (grade 3b). The median hospital stay was 5 days (IQR: 4-6). Laparoscopic NOSE-colectomy is safe and feasible with good short-term outcome. This study concerning a standardized operative technique is the first in literature reporting on a large group of patients.

This article discusses about Pedagogical content knowledge (PCK) profile of prospective physics teachers on optical geometry materials. Data collected using interview and questionnaire, and the data were analyzed descriptively. The results showed that PCK is an unfamiliar term to students. The extreme findings in this study is the lack of understanding of PCK by prospective physics teachers relating to the importance of recognizing the characteristics of students and how to manage questions from students, which teacher has to directly answer questions from students, and how to respond to the students’ incorrect answer, mostly prospective physics teachers assume that in case of the students answer incorrectly, the students should be directly blamed. Prospective physics teachers have not yet integrated the pedagogical knowledge with the content knowledge in their possess learning it he optical geometry material.

Although pulsed radiofrequency (PRF) method for lumbosacral radicular pain (LSRP) is reportedly effective, there are no prospective controlled trials. We assessed the long-term efficacy of PRF of the dorsal root ganglion and nerve roots for LSRP as compared with nerve root block (RB). The study included 27 patients suffering from LSRP. The design of this study was randomized with a RB control. In the PRF group, the PRF current was applied for 120 seconds after RB. In the RB group, the patients received RB only. Visual analogue scale (VAS) was assessed immediately before, and immediately, 2 hours, 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year after the procedure. P<0.05 was regarded as denoting statistical significance. In both groups, the VAS not only of short-term but also of long-term (6 months and 1 year after procedure) significantly decreased as compared with that before treatment (P<0.05). There were no significant differences of VAS between the two groups at the same time points. This study indicates that PRF adjacent to the dorsal root ganglion and nerve roots for LSRP has long-term effects. There were no significant differences of long-term effects between the two groups.

Virtual reality-based prospective memory training program for people with acquired brain injury.

PubMed

Yip, Ben C B; Man, David W K

2013-01-01

Acquired brain injuries (ABI) may display cognitive impairments and lead to long-term disabilities including prospective memory (PM) failure. Prospective memory serves to remember to execute an intended action in the future. PM problems would be a challenge to an ABI patient's successful community reintegration. While retrospective memory (RM) has been extensively studied, treatment programs for prospective memory are rarely reported. The development of a treatment program for PM, which is considered timely, can be cost-effective and appropriate to the patient's environment. A 12-session virtual reality (VR)-based cognitive rehabilitation program was developed using everyday PM activities as training content. 37 subjects were recruited to participate in a pretest-posttest control experimental study to evaluate its treatment effectiveness. Results suggest that significantly better changes were seen in both VR-based and real-life PM outcome measures, related cognitive attributes such as frontal lobe functions and semantic fluency. VR-based training may be well accepted by ABI patients as encouraging improvement has been shown. Large-scale studies of a virtual reality-based prospective memory (VRPM) training program are indicated.

Justice in the context of family balancing

PubMed Central

Sharp, Richard R.

2013-01-01

Bioethics and feminist scholarship has explored various justice implications of non-medical sex selection and family balancing. However, prospective users’ viewpoints have been absent from the debate over the socially acceptable bounds of non-medical sex selection. This qualitative study provides a set of empirically-grounded perspectives on the moral values that underpin prospective users’ conceptualizations of justice in the context of a family balancing program in the United States. The results indicate that couples pursuing family balancing understand justice primarily in individualist and familial terms rather than in terms of social justice for women and girls or for children resulting from sex selection. Study participants indicated that an individual’s desire for gender balance in their family is ethically complex and may not be inherently sexist, immoral or socially consequential, particularly given the social context in which they live. Our findings suggest that the social conditions that contribute to prospective users’ desires for gender balance in their families may direct them away from recognizing or engaging broader social justice concerns relating to sexism and stratified reproduction.

Malnutrition in hospitalized patients is associated with an increased risk of death, in both the short and the long term. The purpose of this study was to determine which nutrition-related risk index predicts long-term mortality better (three years) in patients who receive total parenteral nutrition (TPN). This prospective, multicenter study involved noncritically ill patients who were prescribed TPN during hospitalization. Data were collected on Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Geriatric Nutritional Risk Index (GNRI), body mass index, albumin and prealbumin, as well as long-term mortality. Over the 1- and 3-year follow-up periods, 174 and 244 study subjects (28.8% and 40.3%) respectively, died. Based on the Cox proportional hazards survival model, the nutrition-related risk indexes most strongly associated with mortality were SGA and albumin (<2.5 g/dL) (after adjustment for age, gender, C-reactive protein levels, prior comorbidity, mean capillary blood glucose during TPN infusion, diabetes status prior to TPN, diagnosis, and infectious complications during hospitalization). The SGA and very low albumin levels are simple tools that predict the risk of long-term mortality better than other tools in noncritically ill patients who receive TPN during hospitalization.

Short-term stress, but not mucosal healing nor depression was predictive for the risk of relapse in patients with ulcerative colitis: a prospective 12-month follow-up study.

PubMed

Langhorst, Jost; Hofstetter, Anna; Wolfe, Fred; Häuser, Winfried

2013-10-01

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. Psychological factors such as depression and stress are under debate to contribute to the risk of relapse. The impact of mucosal healing to reduce the risk of relapse had not been studied prospectively. The aim of this study was to identify whether depression and stress increase and mucosal healing reduces the risk of clinical relapse in patients with UC in clinical remission. Patients in clinical remission were followed prospectively for 1 year, or less if they relapsed. Endoscopy and histology score and long-term perceived stress (Perceived Stress Questionnaire) were measured at baseline. Mucosal healing was defined by a Mayo Endoscopy score of 0-1. Depression (Hospital Anxiety and Depression Scale) and acute perceived stress (Cohen Perceived Stress Scale) were measured at baseline and after 1, 3, 6, 9, and 12 months. A time-dependent multivariate Cox regression model determined the predictors of time to relapse. Seventy-five patients were included into final analysis, of which 28 (37.3%) relapsed. Short-term stress at the last visit before relapse (hazard ratio [HR] = 1.05, 95% confidence interval [CI] = 1.01-1.10) and male gender (HR = 2.38, 95% CI = 1.01-5.61), but not baseline mucosal healing (HR = 0.86, 95% CI = 0.35-2.11), baseline long-term stress (HR = 0.20, 95% CI = 0.01-3.31), and depression at the last visit before relapse (HR = 1.08, 95% CI = 0.95-1.22) were predictive for a relapse. Short-term stress but not depression nor mucosal healing was predictive for the risk of relapse in patients with UC in clinical remission. Larger multicentre studies are necessary to confirm our findings.

Emerging indications of endoscopic radiofrequency ablation

2015-01-01

Introduction Radiofrequency ablation (RFA) is a well-validated treatment of dysplastic Barrett's esophagus. Other indications of endoscopic RFA are under evaluation. Results Four prospective studies (total 69 patients) have shown that RFA achieved complete remission of early esophageal squamous intra-epithelial neoplasia at a rate of 80%, but with a substantial risk of stricture. In the setting of gastric antral vascular ectasia, two prospective monocenter studies, and a retrospective multicenter study, (total 51 patients), suggest that RFA is efficacious in terms of reducing transfusion dependency. In the setting of chronic hemorrhagic radiation proctopathy, a prospective monocenter study and a retrospective multicenter study (total 56 patients) suggest that RFA is an efficient treatment. A retrospective comparative study (64 patients) suggests that RFA improves stents patency in malignant biliary strictures. Conclusions Endoscopic RFA is an upcoming treatment modality in early esophageal squamous intra-epithelial neoplasia, as well as in gastric, rectal, and biliary diseases. PMID:26279839

Proton pump inhibitors (PPIs) are a widely used class of drugs because of a generally acceptable safety profile. Among recently raised safety issues of the long-term use of PPIs is the increased risk of developing hypomagnesemia. As there have been very few prospective studies measuring serum magnesium levels before and after PPI therapy, we aimed to prospectively assess the potential association between PPI therapy for 12 months and the risk of hypomagnesemia as well as the incidence of new-onset hypomagnesemia during the study. In addition, the association of PPI therapy with the risk of hypocalcemia was assessed. The study included 250 patients with normal serum magnesium and total calcium levels, who underwent a long-term PPI treatment. Serum magnesium, total calcium, and parathormone (PTH) levels were measured at baseline and after 12 months. Of the 250 study participants, 209 completed 12 months of treatment and were included in the statistical analysis. The Wilcoxon signed rank test showed no statistically significant differences in serum magnesium levels between measurements at two different time points. However, there were statistically significant differences in serum total calcium and PTH levels in PPI users. Stable serum magnesium levels were demonstrated after 12 months and no association between PPI use and risk of hypomagnesemia was shown in the general population. Significant reductions of serum total calcium levels were demonstrated among PPI users; nevertheless, further research is required before recommending any serum calcium and PTH level monitoring in patients initiated on long-term PPI therapy.

The efficacy and adverse effects of in vitro fertilization and embryo transfer.

PubMed

Corabian, P; Hailey, D

1999-01-01

This paper examines the current status of in vitro fertilization and embryo transfer (IVF-ET) as a treatment for various types of infertility. We reviewed studies on the efficacy and safety of IVF-ET and intracytoplasmic sperm injection (ICSI) plus IVF-ET, compared with conventional treatment or no treatment for various infertility diagnoses. Material retrieved included English language publications between 1992 and January 1997 that reported the results of prospective controlled clinical trials, cohort studies, and retrospective comparative studies with large series, and reviews presenting risks, complications, and longer-term health consequences associated with IVF-ET and ICSI. No adequate prospective comparative studies of sufficient power on the use of IVF-ET for specific infertility diagnoses have been reported to date. Most of the published reports concerning results with IVF-ET as a treatment of infertility have been based upon small, uncontrolled studies, with various methodological weaknesses. Reported results are not directly comparable. There are few follow-up data on outcomes after pregnancy is established or on long-term health consequences of the use of IVF-ET on mothers and their babies. IVF-ET has diffused widely without comprehensive assessment of its efficacy and safety. The available evidence supports its use only for severe bilateral tubal occlusion. For other diagnoses of infertility the evidence is limited and does not establish whether IVF-ET is effective. Long-term, well-designed, prospective clinical trials are required to determine when and for what indications IVF-ET is effective and what its health effects are on both mothers and their babies.

Performance of the modified Poisson regression approach for estimating relative risks from clustered prospective data.

PubMed

Yelland, Lisa N; Salter, Amy B; Ryan, Philip

2011-10-15

Modified Poisson regression, which combines a log Poisson regression model with robust variance estimation, is a useful alternative to log binomial regression for estimating relative risks. Previous studies have shown both analytically and by simulation that modified Poisson regression is appropriate for independent prospective data. This method is often applied to clustered prospective data, despite a lack of evidence to support its use in this setting. The purpose of this article is to evaluate the performance of the modified Poisson regression approach for estimating relative risks from clustered prospective data, by using generalized estimating equations to account for clustering. A simulation study is conducted to compare log binomial regression and modified Poisson regression for analyzing clustered data from intervention and observational studies. Both methods generally perform well in terms of bias, type I error, and coverage. Unlike log binomial regression, modified Poisson regression is not prone to convergence problems. The methods are contrasted by using example data sets from 2 large studies. The results presented in this article support the use of modified Poisson regression as an alternative to log binomial regression for analyzing clustered prospective data when clustering is taken into account by using generalized estimating equations.

Development and Implementation of Science and Technology Ethics Education Program for Prospective Science Teachers

NASA Astrophysics Data System (ADS)

Rhee, Hyang-yon; Choi, Kyunghee

2014-05-01

The purposes of this study were (1) to develop a science and technology (ST) ethics education program for prospective science teachers, (2) to examine the effect of the program on the perceptions of the participants, in terms of their ethics and education concerns, and (3) to evaluate the impact of the program design. The program utilized problem-based learning (PBL) which was performed as an iterative process during two cycles. A total of 23 and 29 prospective teachers in each cycle performed team activities. A PBL-based ST ethics education program for the science classroom setting was effective in enhancing participants' perceptions of ethics and education in ST. These perceptions motivated prospective science teachers to develop and implement ST ethics education in their future classrooms. The change in the prospective teachers' perceptions of ethical issues and the need for ethics education was greater when the topic was controversial.

The changing face of bipolar disorder: adolescence to adulthood.

PubMed

Jairam, R; Hanstock, T L; Cahill, C M; Hazell, P L; Walter, G J; Malhi, G S

2008-02-01

Over the past decade, there has been greater acceptance of the existence of bipolar disorder (BD) in adolescents. The onset of BD during this period severely affects the acquisition of key developmental skills. Debate around diagnosis, comorbidity and treatment is strong and little is known about the long-term impact BD has on an adolescents as they approach adulthood, from both illness and functional perspectives. A review of psychological and medical databases using the search terms ''adolescent onset'', ''pediatric onset'', ''juvenile onset'', ''bipolar disorder'', ''course'' and ''outcome'' was conducted. Emphasis was placed on the information available from studies, which have described the outcome of adolescent onset BD either prospectively, retrospectively, or both. Twelve studies were identified that focused on the long-term course of adolescent onset BD. Findings on the course and outcomes are conflicting. These studies are from few centres or research groups and have small sample sizes, varied methodologies and relatively brief follow-up durations. There are few studies available on the course and outcome of adolescent onset BD. Although there seems to be less controversy in this age group compared to the prepubertal age group, there remains a need for prospective studies of large systematically ascertained samples.

Impulsivity-hyperactivity and subtypes of aggression in early childhood: an observational and short-term longitudinal study.

PubMed

Ostrov, Jamie M; Godleski, Stephanie A

2009-08-01

This short-term longitudinal study (N = 112) was conducted to explore the concurrent and prospective associations between teacher-reported impulsive-hyperactive behavior and observed relational and physical aggression during early childhood (M = 45.54 months old, SD = 9.07). Multiple informants and methods including observational methods (i.e., 160 min per child) were used to assess aggression and impulsivity-hyperactivity. All measures were found to be valid and reliable. Prospective hierarchical regression analyses revealed that impulsivity-hyperactivity was associated with increases in observed physical aggression across time, controlling for initial relational aggression and gender. These findings add to the growing developmental psychopathology literature that suggests that distinguishing between subtypes of aggression during early childhood may be important for understanding the course of impulsivity-hyperactivity in young children. Implications for practice are discussed.

The aim of this prospective randomized multicenter study was to compare TVT (tension-free vaginal tape) with TVT-Secur in terms of efficacy and safety. We set out to enrol 280 stress incontinent women with a half time interim analysis of short-term cure and a continuous registration of adverse events. Of 133 randomized women, 126 were operated and 123 (TVT n = 62, TVT-Secur n = 61) available for 2 months follow-up. No significant differences were found between groups regarding demographics or grade of incontinence. At 2 months follow-up, subjective cure rate following TVT-Secur was significantly lower than for TVT (72% and 92%, respectively, p = 0.01). Three major complications occurred in the TVT-Secur group: tape erosion into the urethra, a tape inadvertently placed inside the bladder, and an immediate postoperative bleeding from the corona mortis. No major complications occurred in the TVT group. No significant differences were found between groups regarding perioperative bleeding, hospital stay, urge symptoms, or postoperative urinary tract infections. Median time for surgery was 13 and 22 min for TVT-Secur and TVT, respectively (p < 0.0001). In a prospective randomized controlled study, the TVT-Secur procedure had a significantly lower subjective cure rate than the retropubic TVT procedure. Due to this, in addition to three serious complications in the TVT-Secur group, we decided to stop further enrolment after the interim analysis. We discourage from further use of the TVT-Secur.

To assess the prospective associations between self-reported physical capacity and risk of long-term sickness absence among female health care workers. Female health care workers answered a questionnaire about physical capacity and were followed in a national register of sickness absence lasting for two or more consecutive weeks during 1-year follow-up. Using Cox regression hazard ratio analyses adjusted for age, smoking, body mass index, physical workload, job seniority, psychosocial work conditions, and previous sickness absence, we modeled risk estimates for sickness absence from low and medium physical capacity. Low and medium aerobic fitness, low muscle strength, low flexibility, and low overall physical capacity significantly increased the risk for sickness absence with 20% to 34% compared with health care workers with high capacity. Low physical capacity increases the risk of long-term sickness absence among female health care workers.

Relationship and task conflict at work: interactive short-term effects on angry mood and somatic complaints.

PubMed

Meier, Laurenz L; Gross, Sven; Spector, Paul E; Semmer, Norbert K

2013-04-01

Our research examined short-term within-person effects of relationship and task conflict on angry mood and somatic complaints. We assumed that conflicts of both kinds would be prospectively related to both indicators of impaired well-being, that the effect of relationship conflict would be stronger than the effect of task conflict, and that the effect of relationship conflict would be stronger when task conflict is low than when it is high. We tested our hypotheses with a daily diary study with ratings made 3 times/day for 2 weeks, involving 131 participants. We found a prospective main effect of relationship conflict on angry mood, but not on somatic complaints. In contrast, controlling for relationship conflict, task conflict was unrelated to both angry mood and somatic complaints. Supporting our assumption, task conflict moderated the effect of relationship conflict. Relationship conflict had a prospective effect on angry mood and somatic complaints that lasted until the next day if, and only if, task conflict was low.

Prospective Validation of Pre-earthquake Atmospheric Signals and Their Potential for Short–term Earthquake Forecasting

2015-04-01

We are presenting the latest development in multi-sensors observations of short-term pre-earthquake phenomena preceding major earthquakes. Our challenge question is: "Whether such pre-earthquake atmospheric/ionospheric signals are significant and could be useful for early warning of large earthquakes?" To check the predictive potential of atmospheric pre-earthquake signals we have started to validate anomalous ionospheric / atmospheric signals in retrospective and prospective modes. The integrated satellite and terrestrial framework (ISTF) is our method for validation and is based on a joint analysis of several physical and environmental parameters (Satellite thermal infrared radiation (STIR), electron concentration in the ionosphere (GPS/TEC), radon/ion activities, air temperature and seismicity patterns) that were found to be associated with earthquakes. The science rationale for multidisciplinary analysis is based on concept Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) [Pulinets and Ouzounov, 2011], which explains the synergy of different geospace processes and anomalous variations, usually named short-term pre-earthquake anomalies. Our validation processes consist in two steps: (1) A continuous retrospective analysis preformed over two different regions with high seismicity- Taiwan and Japan for 2003-2009 (2) Prospective testing of STIR anomalies with potential for M5.5+ events. The retrospective tests (100+ major earthquakes, M>5.9, Taiwan and Japan) show STIR anomalous behavior before all of these events with false negatives close to zero. False alarm ratio for false positives is less then 25%. The initial prospective testing for STIR shows systematic appearance of anomalies in advance (1-30 days) to the M5.5+ events for Taiwan, Kamchatka-Sakhalin (Russia) and Japan. Our initial prospective results suggest that our approach show a systematic appearance of atmospheric anomalies, one to several days prior to the largest earthquakes That feature could be further studied and tested for prospective early warnings based on the multi-sensors detection of pre-earthquake atmospheric signals.

Objective To describe (1) the relationship between nutrition and the preterm-at-term infant phenotype, (2) phenotypic differences between preterm-at-term infants and healthy term born infants and (3) relationships between somatic and brain MRI outcomes. Design Prospective observational study. Setting UK tertiary neonatal unit. Participants Preterm infants (<32 weeks gestation) (n=22) and healthy term infants (n=39) Main outcome measures Preterm nutrient intake; total and regional adipose tissue (AT) depot volumes; brain volume and proximal cerebral arterial vessel tortuosity (CAVT) in preterm infants and in term infants. Results Preterm nutrition was deficient in protein and high in carbohydrate and fat. Preterm nutrition was not related to AT volumes, brain volume or proximal CAVT score; a positive association was noted between human milk intake and proximal CAVT score (r=0.44, p=0.05). In comparison to term infants, preterm infants had increased total adiposity, comparable brain volumes and reduced proximal CAVT scores. There was a significant negative correlation between deep subcutaneous abdominal AT volume and brain volume in preterm infants (r=−0.58, p=0.01). Conclusions Though there are significant phenotypic differences between preterm infants at term and term infants, preterm macronutrient intake does not appear to be a determinant. Our preliminary data suggest that (1) human milk may exert a beneficial effect on cerebral arterial vessel tortuosity and (2) there is a negative correlation between adiposity and brain volume in preterm infants at term. Further work is warranted to see if our findings can be replicated and to understand the causal mechanisms. PMID:24860004

The hypothesis that "cell phone induces brain tumor" has become a target of much controversy for several decades and is still a matter of debate even now. We aim to make a systematic review and meta-analysis based on published studies on glioma to identify current evidences for evaluating mobile phones and glioma risk, especially on long-term use of mobile phones. The study was conducted according to the Cochrane systematic review methods and reported according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement according to a prospective research protocol accessed via http://www.crd.york.ac.uk/prospero. The software RevMan 5 was used for statistic analysis. Latency and lateralization were used for the examining the dose-response relationship. Overall evidence suggested the increased risk of glioma among long-term ipsilateral users of mobile phone with an odds ratio (OR) of 1.46[1.12, 1.92] based on meta-analysis. Especially, for low-grade glioma, long-term use yielded an OR value of 2.27 [1.81, 2.85]. The evidence is currently insufficient on this issue, especially on long-term use of mobile phone. Neither a definite answer nor a clear explanation may be offered for the relationship. And larger prospective trials are warranted.

Background: Long-term aircraft noise exposure may increase the risk of cardiovascular disease, but no study has investigated chronic effects on the metabolic system. Objectives: The aim of this study was to investigate effects of long-term aircraft noise exposure on body mass index (BMI), waist circumference, and type 2 diabetes. Furthermore, we explored the modifying effects of sleep disturbance. Methods: This prospective cohort study of residents of Stockholm County, Sweden, followed 5,156 participants with normal baseline oral glucose tolerance tests (OGTT) for up to 10 years. Exposure to aircraft noise was estimated based on residential history. Information on outcomes and confounders was obtained from baseline and follow-up surveys and examinations, and participants who developed prediabetes or type 2 diabetes were identified by self-reported physician diagnosis or OGTT at follow-up. Adjusted associations were assessed by linear, logistic, and random-effects models. Results: The mean (± SD) increases in BMI and waist circumference during follow-up were 1.09 ± 1.97 kg/m2 and 4.39 ± 6.39 cm, respectively. The cumulative incidence of prediabetes and type 2 diabetes was 8% and 3%, respectively. Based on an ordinal noise variable, a 5-dB(A) increase in aircraft noise was associated with a greater increase in waist circumference of 1.51 cm (95% CI: 1.13, 1.89), fully adjusted. This association appeared particularly strong among those who did not change their home address during the study period, which may be a result of lower exposure misclassification. However, no clear associations were found for BMI or type 2 diabetes. Furthermore, sleep disturbances did not appear to modify the associations with aircraft noise. Conclusions: Long-term aircraft noise exposure may be linked to metabolic outcomes, in particular increased waist circumference.

Prospective data are scarce on the relation of red meat, seafood, and poultry consumption with hypertension risk. Although red and processed meats are generally considered to have adverse cardiovascular consequences, seafood is believed to be protective and poultry's effect is controversial. We prospectively examined the independent association of long-term intake of animal flesh with incident hypertension in three longitudinal cohort studies of nonhypertensive individuals: Nurses' Health Study (NHS, n = 62 273 women), Nurses' Health Study II (NHS II, n = 88 831 women), and Health Professionals Follow-Up Study (HPFS, n = 37 414 men). We used multivariable Cox proportional hazards regression to study the associations of different types of animal flesh with the risk of developing hypertension while controlling for other hypertension risk factors. We then used fixed-effects meta-analysis to derive pooled estimates of effect. Compared with participants whose consumption was less than 1 serving/month, the pooled hazard ratios among those whose intake was at least 1 serving/day were 1.30 (95% confidence interval 1.23-1.39) for total meat (a combination of processed and unprocessed red meat), 1.22 (1.12-1.34) for poultry, and 1.05 (0.98-1.13) for seafood. Seafood was associated with an increased risk of hypertension in HPFS and NHS II, but not NHS. Consumption of any animal flesh at least 1 serving/day was associated with an increased hypertension risk [pooled hazard ratio = 1.30 (1.16-1.47)]. Long-term intake of meat and poultry were associated with increased risk of hypertension. In contrast to our hypothesis, we found a weak but significant trend toward an increased risk of hypertension with increasing seafood consumption.

Para-Umbilical Hernia (PUH) is one of the most common surgical problems. Since the prosthetic repair has become the standard of practice for inguinal hernia management, the same has been adapted for para-umbilical hernia management with better outcome. There is still debate going on regarding the optimal surgical approach. There are very few prospective studies comparing the laparoscopic and open method of para-umbilical hernia mesh repair. This study compared the short term outcomes following laparoscopic versus open mesh repair of PUH. To compare the early complications of open repair with laparoscopic repair of PUH. To compare the post-operative hospital stay of open repair with laparoscopic repair of PUH. This was a prospective comparative clinical study done from August 2014 to August 2016. All the patients above the age of 13 who attended our surgical outpatient department with PUH were taken into our study. Exclusion criteria included 1) Patients with obstructed or strangulated PUH 2) Patients with abdominal malignancies 3) Patients with coagulopathy, severe cardiopulmonary disease, ascites and renal failure 4) Patients who had PUH repair in combination with another major surgical operation such as laparoscopic cholecystectomy and inguinal hernia repair 5) Patients with recurrent PUH. Institute Ethical Committee clearance was obtained for this study. Out of 40 patients with PUH, 20 received open meshplasty and 20 patients received laparoscopic meshplasty. Postoperative pain and length of hospital stay is significantly less in laparoscopic PUH repair. Postoperative complications like wound infection, seroma, and haematoma are relatively less in laparoscopic group though statistically not significant. Laparoscopic PUH repair has significantly better outcome in terms of postoperative pain and postoperative hospital stay.

To evaluate telescopic crown (TC), bar, and locator attachments used in removable four implant-supported overdentures for patients with edentulous maxillae. A total of 30 maxillary edentulous patients were enrolled in a 3-year prospective study. Ten patients (group A) were treated with overdentures supported by TCs, 10 patients (group B) with overdentures supported by bar attachments, and 10 patients (group C) with overdentures supported by locator attachments. A total of 120 implants were used to restore oral function. During the 3-year follow-up period, implant survival and success rates, biologic and mechanical complications, prosthodontic maintenance efforts, and patient satisfaction were evaluated. All 30 patients were available for the 3-year follow-up and exhibited 100% implant survival and success rates. Peri-implant marginal bone resorption was not statistically significant for the three groups. There were lower plaque, bleeding, gingiva, and calculus indices in group C compared with groups A and B. The number of prosthodontic maintenance visits revealed eight complications in the TC group, seven complications in the bar group, and four complications in the locator group. However, there were no differences in the clinical effects of the overdentures in the three groups. Within the limits of this prospective study, it was concluded that the locator system produced superior clinical results compared with the TC and bar attachments in terms of peri-implant hygiene parameters, the frequency of prosthodontic maintenance measures, cost, and ease of denture preparation. However, longer-term prospective studies are required to confirm these results.

Pylorus-preserving pancreatoduodenectomy (PPPD) has been associated with a high incidence of delayed gastric emptying (DGE). There are few studies comparing DGE associated with PPPD and subtotal stomach-preserving pancreatoduodenectomy (SSPPD). Moreover, differences between the procedures with respect to long-term results have not been reported. A prospective randomized study was conducted to compare perioperative complications and long-term nutritional status with PPPD and SSPPD. One hundred patients with periampullary lesions were randomized to receive either PPPD (n = 50) or SSPPD (n = 50). All patients were followed up for 3 years after surgery or to the time of recurrence to evaluate nutritional status for the study. The effects of the procedure, age, and malignancy on changes in nutritional indicators were estimated with linear mixed models. This study was registered at UMIN Clinical Trials Registry (UMIN 000012337). The incidence of DGE assessed by the International Study Group of Pancreatic Surgery was 20% with PPPD and 12% with SSPPD (P = 0.414). There were no significant differences between the two procedures on postoperative serum albumin levels, serum total cholesterol levels, and body mass index during the 3-year follow-up period. SSPPD is equally effective in DGE occurrence rate and long-term nutritional status comparing to PPPD. © 2014 Wiley Periodicals, Inc.

Vaginal breech delivery: results of a prospective registration study

PubMed Central

2013-01-01

Background Most countries recommend planned cesarean section in breech deliveries, which is considered safer than vaginal delivery. As one of few countries in the western world Norway has continued to practice planned vaginal delivery in selected women. The aim of this study is to evaluate prospectively registered neonatal and maternal outcomes in term singleton breech deliveries in a Norwegian hospital during a ten years period. We aim to compare maternal and neonatal outcomes in term breech pregnancies subjected either to planned vaginal or elective cesarean section. Methods A prospective registration study including 568 women with term breech deliveries (>37 weeks) consecutively registered at Sorlandet Hospital Kristiansand between 2001 and 2011. Fetal and maternal outcomes were compared according to delivery method; planned vaginal delivery versus planned cesarean section. Results Of 568 women, elective cesarean section was planned in 279 (49%) cases and vaginal delivery was planned in 289 (51%) cases. Acute cesarean section was performed in 104 of the planned vaginal deliveries (36.3%). There were no neonatal deaths. Two cases of serious neonatal morbidity were reported in the planned vaginal group. One infant had seizures, brachial plexus injury, and cephalhematoma. The other infant had 5-minutes Apgar < 4. Twenty-nine in the planned vaginal group (10.0%) and eight in the planned cesarean section group (2.9%) (p < 0.001) were transferred to the neonatal intensive care unit. However, only one infant was admitted for ≥4 days. According to follow-up data (median six years) none of these infants had long-term sequelae. Regarding maternal morbidity, blood loss was the only variable that was significantly higher in the planned cesarean section group versus in the vaginal delivery group (p < 0.001). Conclusions Strict guidelines were followed in all cases. There were no neonatal deaths. Two infants had serious neonatal morbidity in the planned vaginal group without long-term sequelae.

The aim of the present prospective study was to evaluate changes in plasma GABA concentration in relation to clinical response during vigabatrin treatment of epilepsy. We studied 29 patients with uncontrolled partial-onset seizures during open add-on vigabatrin treatment and measured plasma GABA and vigabatrin concentrations by a sensitive HPLC method. Following short-term treatment 17 out of 28 patients had a seizure reduction of > 50% (responders). After long-term treatment 16 out of 22 patients were responders. There was no difference between responders and nonresponders regarding pretreatment seizure frequency, treatment duration, vigabatrin dose, or plasma vigabatrin concentration. Responders had a significant (p < 0.001) increase in mean plasma GABA both after short-term (from 0.380 to 0.530 nmol/ml; mean increase: 48%) and after long-term (from 0.392 to 0.618 nmol/ml; mean increase: 71%) vigabatrin treatment, whilst nonresponders had no significant changes in GABA levels. However, since plasma GABA increased in a subgroup of nonresponders, mean plasma GABA levels did not differ between responders and nonresponders. Although plasma GABA increased significantly in the responder but not in the nonresponder group during vigabatrin treatment of patients with epilepsy, it does not seem to be a reliable marker of individual clinical response to vigabatrin treatment.

The Randomised Intervention Treatment of Angina (RITA) Trial protocol: a long term study of coronary angioplasty and coronary artery bypass surgery in patients with angina.

The Randomised Intervention Treatment of Angina (RITA) Trial is a prospective, randomised study to compare the short term and long term effects of percutaneous transluminal coronary angioplasty and coronary artery bypass surgery. During the study a register of patients undergoing coronary arteriography at the fourteen participating centres is being maintained to assess the overall context of patient recruitment. Patients with arteriographically proven coronary artery disease are considered for the trial if the participating cardiologist and surgeon agree that equivalent revascularisation could be achieved by either treatment method. Patients who satisfy the trial entry criteria are randomised to treatment by coronary angioplasty or coronary artery bypass surgery, with prospective stratification into groups with one, two, or three treatment vessels. Randomisation implies an intention to treat the patient by the assigned procedure and the analysis of long term results will include all randomised cases. The trial will recruit at least 1000 patients who will be followed for five years. The major trial end points include death, new myocardial infarction, and new coronary angioplasty or coronary artery bypass procedures. Other outcome measures include symptom and employment status, quality of life, exercise tolerance, and left ventricular function. PMID:2486557

In this study, we examined the mediating role of university students' coping strategies in the unique/additive influence of affective states and goal motivation on upward changes in affect during a midterm exam period. Using a short-term prospective design, key assumptions from the self-concordance model and the broaden-and-build theory were drawn upon to determine whether coping strategies are influenced by goal motivation and affective states, while also subsequently influencing short-term changes in affective states during a semester. A sample of 272 students (79% females and 21% males) participated in a study in which they completed questionnaires twice during the semester. Results of structural equation modeling, using a true latent change approach, have generally supported our hypotheses. Positive affective states and autonomous goal motivation prospectively predicted task-oriented coping which, in turn, was associated with increases in positive affect. Negative affective states and controlled goal motivation prospectively predicted disengagement-oriented coping which, in turn, was associated with increases in negative affect. Coping partially mediates the unique association of affect and goal motivation with changes in affective states of university students.

Background The number of percutaneous coronary interventions (PCI) in China has increased more than 20‐fold over the last decade. Consequently, there is a need for national‐level information to characterize PCI indications and long‐term patient outcomes, including health status, to understand and improve evolving practice patterns. Objectives: This nationwide prospective study of patients receiving PCI is to: (1) measure long‐term clinical outcomes (including death, acute myocardial infarction [AMI], and/or revascularization), patient‐reported outcomes (PROs), cardiovascular risk factor control and adherence to medications for secondary prevention; (2) determine patient‐ and hospital‐level factors associated with care process and outcomes; and (3) assess the appropriateness of PCI procedures. Methods: The China Patient‐centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI has enrolled 5,000 consecutive patients during 2012–2014 from 34 diverse hospitals across China undergoing PCI for any indication. We abstracted details of patient's medical history, treatments, and in‐hospital outcomes from medical charts, and conducted baseline, 1‐, 6‐, and 12‐month interviews to characterize patient demographics, risk factors, clinical presentation, healthcare utilization, and health status using validated PRO measures. The primary outcome, a composite measure of death, AMI and/or revascularization, as well as PROs, medication adherence and cardiovascular risk factor control, was assessed throughout the 12‐month follow‐up. Blood and urine samples were collected at baseline and 12 months and stored for future analyses. To validate reports of coronary anatomy, 2,000 angiograms are randomly selected and read by two independent core laboratories. Hospital characteristics regarding their facilities, processes and organizational characteristics are assessed by site surveys. Conclusion: China PEACE Prospective Study of PCI will be the first study to generate novel, high‐quality, comprehensive national data on patients’ socio‐demographic, clinical, treatment, and metabolic/genetic factors, and importantly, their long‐term outcomes following PCI, including health status. This will build the foundation for PCI performance improvement efforts in China. © 2016 The Authors. Catheterization and Cardiovascular Interventions. Published by Wiley Periodicals, Inc.

The purpose of this study is to examine the usability of biodegradable synthetic polyurethane foam (BSPF) after septoplasty by comparing it with Merocel and silicone intranasal splints as packing materials in terms of patient comfort and efficiency. A prospective, unmasked, randomized trial. A tertiary referral center. This study was designed to be a prospective, randomized clinical trial. Sixty-eight patients who underwent septoplasty were included in this study. The patients were randomized to receive Merocel, silicone intranasal septal splint (INS), or BSPF after septoplasty. Clinical efficacy on bleeding, pain, and subjective symptoms related to packing materials was evaluated. There was a statistically significant difference between the Merocel group and the other 2 groups in terms of bleeding and adhesion. The average score on the pain scale was 2.47 ± 1.01 for BSPF, 3.68 ± 1.27 for INS, and 6 ± 2.21 for Merocel. Scores on general satisfaction scales were 6.95 ± 1.42 for Merocel, 8.44 ± 2.12 for INS, and 8.28 ± 1.88 for BSPF. The efficacy of BSPF was comparable with that of Merocel and INS. Biodegradable synthetic polyurethane foam significantly reduced pain and patient discomfort during packing and removal, followed by INS, compared with Merocel.

Obesity is an increasing public health problem. A small number of studies have examined the relationship between obesity and sickness absence, with mixed results, particularly regarding short-term sickness absence. To determine if obesity is associated with short- and long-term sickness absence and to investigate the mechanisms that may underlie any association. Cross-sectional (n = 1489) and prospective (n = 625) analyses were conducted on staff from London Underground Ltd. All participants underwent regular clinical examinations that involved their height and weight being measured, obesity-related medical problems being diagnosed and psychiatric disorders being identified. The number of days taken for short- (<10 days in an episode) and long-term sickness absence were recorded by managers on an electronic database. There was a positive linear association between employees' body mass index (BMI) and the number of days' work missed due to sickness absence on both cross-sectional and prospective analyses (P < 0.001). Obesity was a risk factor for both short- and long-term sickness absence. Obese individuals typically took an extra 4 days sick leave every year. The majority of the increased risk for long-term sickness absence appeared to be mediated via co-morbid chronic medical conditions. The excess short-term sickness absence was not explained by obesity-related medical problems, psychiatric disorders or workplace factors. Obese employees take significantly more short- and long-term sickness absence than workers of a healthy weight. There is growing evidence to support employers becoming more involved in tackling obesity.

Comparing the effectiveness of using generic and specific search terms in electronic databases to identify health outcomes for a systematic review: a prospective comparative study of literature search methods

MacLean, Alice; Sweeting, Helen; Hunt, Kate

2012-01-01

Objective To compare the effectiveness of systematic review literature searches that use either generic or specific terms for health outcomes. Design Prospective comparative study of two electronic literature search strategies. The ‘generic’ search included general terms for health such as ‘adolescent health’, ‘health status’, ‘morbidity’, etc. The ‘specific’ search focused on terms for a range of specific illnesses, such as ‘headache’, ‘epilepsy’, ‘diabetes mellitus’, etc. Data sources The authors searched Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO and the Education Resources Information Center for studies published in English between 1992 and April 2010. Main outcome measures Number and proportion of studies included in the systematic review that were identified from each search. Results The two searches tended to identify different studies. Of 41 studies included in the final review, only three (7%) were identified by both search strategies, 21 (51%) were identified by the generic search only and 17 (41%) were identified by the specific search only. 5 of the 41 studies were also identified through manual searching methods. Studies identified by the two ELS differed in terms of reported health outcomes, while each ELS uniquely identified some of the review's higher quality studies. Conclusions Electronic literature searches (ELS) are a vital stage in conducting systematic reviews and therefore have an important role in attempts to inform and improve policy and practice with the best available evidence. While the use of both generic and specific health terms is conventional for many reviewers and information scientists, there are also reviews that rely solely on either generic or specific terms. Based on the findings, reliance on only the generic or specific approach could increase the risk of systematic reviews missing important evidence and, consequently, misinforming decision makers. However, future research should test the generalisability of these findings. PMID:22734117

The current study involved a short-term longitudinal study of young children (M = 44.56 months, SD = 11.88, N = 103) to test the prospective associations between peer victimization and aggression subtypes. Path analyses documented that teacher-reported physical victimization was uniquely associated with increases in observed physical aggression over time. The path model also revealed that teacher-reported relational victimization was uniquely associated with statistically significant increases in observed relational aggression over time. Ways in which these findings extend the extant developmental literature are discussed. © 2010 The Author. Child Development © 2010 Society for Research in Child Development, Inc.

It is critical to establish optimal sample handling conditions for short-term processing and long-term urinary storage prior to widespread clinical deployment and meaningful use in prospective clinical trials. Prospective study. 80 children (median age, 1.1 [IQR, 0.5-4.2] years) undergoing cardiac surgery with cardiopulmonary bypass at our center. 50% of patients had acute kidney injury (defined as ≥50% increase in serum creatinine from baseline). We tested the effect on biomarker concentrations of short-term urine storage in ambient, refrigerator, and freezer conditions. We also tested the effects of multiple freeze-thaw cycles, as well as prolonged storage for 5 years. Urine concentrations of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule 1 (KIM-1), and interleukin 18 (IL-18). All biomarkers were measured using commercially available kits. All 3 biomarkers were stable in urine stored at 4°C for 24 hours, but showed significant degradation (5.6%-10.1% from baseline) when stored at 25°C. All 3 biomarkers showed only a small although significant decrease in concentration (0.77%-2.9% from baseline) after 3 freeze-thaw cycles. Similarly, all 3 biomarkers displayed only a small but significant decrease in concentration (0.84%-3.2%) after storage for 5 years. Only the 3 most widely studied biomarkers were tested. Protease inhibitors were not evaluated. Short-term storage of urine samples for measurement of NGAL, KIM-1, and IL-18 may be performed at 4°C for up to 24 hours, but not at room temperature. These urinary biomarkers are stable at -80°C for up to 5 years of storage. Our results are reassuring for the deployment of these assays as biomarkers in clinical practice, as well as in prospective clinical studies requiring long-term urine storage.

Prospective associations between peer teasing in childhood and young men's obesity.

Kerr, David C R; Gini, Gianluca

Being teased and otherwise victimised by peers during childhood increases risk for obesity. However, few prospective studies have considered whether risk extends to adulthood. We tested whether being teased in childhood predicted higher body mass index (BMI) and increased odds of obesity in early adulthood in a community sample of American males. Boys (n=206) were classified as victims of peer teasing or non-victims (n=55 and 151, respectively) based on mother, father, and teacher reports at ages 10-12 years. BMI was assessed at ages 24 or 32 years for 203 of the participants. Family income, parent and child depressive symptoms, child antisocial behaviour, and childhood BMI were assessed at ages 10-13 years and served as control variables. In unadjusted comparisons, childhood victims did not differ significantly from non-victims on BMI (mean [SD]=27.49 [4.53] and 26.97 [4.60], respectively) or rates of obesity (42% and 31%, respectively) in early adulthood. In adjusted models, no group differences emerged for BMI (β [95% confidence interval (CI)]=.02 [-.09 to .13], p=.77) or obesity (odds ratio [95% CI]=1.58 [.67-3.71], p=.30). Peer victimization has been associated with immediate and long-term maladjustment outcomes that are in some cases life threatening. However, our null results do not support that peer victimization significantly increases long-term risk for obesity, and findings are consistent with two other long-term prospective studies of this issue.

Objective Recurrent suicidal behavior is a defining characteristic of BPD. Although most patients achieve remission of suicidal behaviors over time, 3% to 10% die by suicide, raising the question of whether there is a high risk suicidal subtype in BPD. We are conducting the first longitudinal study of suicidal behavior in BPD to identify prospective predictors of suicide attempts, and characterize BPD patients at highest risk for suicide completion. Method Demographic, diagnostic, clinical and psychosocial risk factors assessed at baseline were examined for predictive association with medically significant suicide attempts using Cox proportional hazards models. Prospective predictors were defined for subjects completing 6 or more years in the study and compared to earlier intervals. Results Among 90 subjects, 25 (27.8%) made at least one suicide attempt in the interval, most occurring in the first two years. Risk of attempt was increased by: a.) low socioeconomic status, b.) poor psychosocial adjustment, c.) a family history of suicide d.) prior psychiatric hospitalization; e.) absence of any outpatient treatment prior to the attempt. Higher global functioning at baseline decreased risk. Conclusion Risk factors predictive of suicide attempts change over time. Acute stressors such as MDD were predictive only in the short term (12 mos.), while poor psychosocial functioning had persistent and long term effects on suicide risk. Half of BPD patients have poor psychosocial outcomes despite symptomatic improvement. A social and vocational rehabilitation model of treatment is needed to decrease suicide risk and optimize long term outcomes in BPD. PMID:22549208

This prospective cohort study examined previously underexplored relations between psychological/social work factors and troubled sleep in order to provide practical information about specific, modifiable factors at work. A comprehensive evaluation of a range of psychological/social work factors was obtained by several designs; i.e., cross-sectional analyses at baseline and follow-up, prospective analyses with baseline predictors (T1), prospective analyses with average exposure across waves as predictor ([T1 + T2] / 2), and prospective analyses with change in exposure from baseline to follow-up as predictor. Participants consisted of a sample of Norwegian employees from a broad spectrum of occupations, who completed a questionnaire at two points in time, approximately two years apart. Cross-sectional analyses at T1 comprised 7,459 participants, cross-sectional analyses at T2 included 6,688 participants. Prospective analyses comprised a sample 5,070 of participants who responded at both T1 and T2. Univariable and multivariable ordinal logistic regressions were performed. Thirteen psychological/social work factors and two aspects of troubled sleep, namely difficulties initiating sleep and disturbed sleep, were studied. Ordinal logistic regressions revealed statistically significant associations for all psychological and social work factors in at least one of the analyses. Psychological and social work factors predicted sleep problems in the short term as well as the long term. All work factors investigated showed statistically significant associations with both sleep items, however quantitative job demands, decision control, role conflict, and support from superior were the most robust predictors and may therefore be suitable targets of interventions aimed at improving employee sleep. © 2016 Associated Professional Sleep Societies, LLC.

Workplace bullying as an antecedent of mental health problems: a five-year prospective and representative study.

PubMed

Einarsen, Ståle; Nielsen, Morten Birkeland

2015-02-01

The present study investigates the proposed long-term relationship between exposure to workplace bullying and subsequent mental health in the form of anxiety and depression with a time lag of 5 years, exploring potential gender differences in these relationships. The study employs a prospective design with a 5-year time lag in a representative sample of the Norwegian workforce. A cohort of 1,613 employees reported on their exposure to workplace bullying and their symptoms of anxiety and depression at both measurement times. The results showed exposure to workplace bullying to be a significant predictor of mental health problems 5 years on, even after controlling for baseline mental health status, gender, age, job-change, job demands and job control, yet for men only. Baseline levels of mental health problems in terms of symptoms of anxiety and depression did not predict subsequent exposure to bullying at follow-up among women, but anxiety did in the case of men. Workplace bullying poses a serious long-term threat to the health and well-being of workers, at least for men. The results of the study pinpoint the need for mental health treatment as well as for preventive measures in relation to workplace bullying, and pinpoint the need for a gender perspective in these studies.

To evaluate the long-term safety of rituximab (RTX) in rheumatoid arthritis (RA) patients in daily clinical practice. This was a multicentre (17 Greek Rheumatology sites), prospective, long-term, pharmacovigilance study of patients with moderate to severe RA and an inadequate response or intolerance to ≥1 anti-tumour necrosis factor (TNF) agents. Adverse events (AEs) were recorded and collected prospectively every 2-6 months. 234 patients (mean age: 59±12.5, 79.5% women, mean DAS28: 5.35±1.32) were included and followed for 27.7 months (median). The overall AEs, serious AE (SAEs) and serious infection (SIEs) rate were 48.36, 6.68 and 2.53/100 patient-years, respectively. Three cases of hepatitis B virus (HBV) reactivation were recorded (two in chronic and one in past HBV infection). Withdrawals due to AEs (5.6%) occurred more frequently during the first cycles of RTX therapy while repeated RTX cycles were not associated with an increased risk of AEs. There were 3 deaths with an incidence rate of 0.69/100 patient-years. Age ≥65 years was associated with a higher incidence rate ratio of AEs and SAEs as compared to <65 years (1.53, p=0.002 and 2.88, p=0.005, respectively). Drug retention rate during 434.28 patient-years of follow-up was 57.3%. Factors associated with drug discontinuation by multivariate analysis included age, baseline swollen joint count and no use of concomitant methotrexate therapy. Long-term RTX therapy in a real-life RA cohort, did not reveal any new safety issues. Advanced age was associated with increased risk of AEs and premature drug discontinuation.

The impact of vegan diet on B-12 status in healthy omnivores: five-year prospective study.

2012-04-02

There are no long-term prospective studies assessing the impact of the vegan diet on vitamin B-12 (B-12) status. Many vegans take B-12 supplements irregularly or refuse to adopt them at all, considering them to be "unnatural" products. The use of B-12 fortified food may be an alternative. Therefore, we aimed to estimate the long-term effect of a vegan diet on serum B-12 concentrations in healthy omnivore adults, comparing the influence of natural products consumption and B-12 fortified food. A five year prospective study was carried out comprising 20 omnivore healthy adult subjects, who moved to strict vegan diet for 5 years. Ten volunteers followed vegan diet based entirely on natural products, while the remaining ten subjects consumed food fortified in B-12. In all subjects serum vitamin B-12 concentration was determined before and 6, 12, 24 and 60 months after the implementation of the diet. A significant decrease (p < 0.0002) of serum B-12 concentrations in the whole studied group was noted after 60 months of vegan diet. However, observed changes were in fact limited to the subgroup consuming exclusively natural products (p < 0.0001). Transition from omnivore to vegan diet is associated with the risk of vitamin B-12 deficiency. B-12 fortified products might constitute a valuable alternative in vegans refusing to take vitamin supplements.

The purpose of this prospective, randomized study was to compare the efficacy of autologous platelet-rich plasma (PRP) injections and arthroscopic lateral release in treating chronic lateral epicondylitis (LE). Patients who had a clinical diagnosis of LE confirmed by ultrasound (US) were included in this study. A total of 101 patients received arthroscopic release (n = 50) or US-guided PRP injections (n = 51). Outcomes were assessed using a visual analog scale for pain, the Patient-Rated Tennis Elbow Evaluation (PRTEE), and a calibrated hand dynamometer for grip strength. Both patient groups experienced significant improvement in all measures. Between-group comparisons showed a significantly higher value in the PRP group only for grip strength at week 8 (P = .0073); all other significant differences were in favor of arthroscopy: overall pain (P = .0021), night pain (P = .0013), and PRTEE score (P = .0013) at week 104 and grip strength at weeks 24, 52, and 104 (all P < .0001). Consumption of rescue pain medication was not significantly different between the groups. The present findings suggest that (1) PRP injections and arthroscopic extensor carpi radialis brevis release are both effective in the short and medium term; (2) PRP patients experienced a significant worsening of pain at 2 years; (3) arthroscopic release ensured better long-term outcomes in terms of pain relief and grip strength recovery; and (4) both procedures were safe and well accepted by patients.

Our previous randomized controlled trial revealed no difference in 2-year overall survival (OS) between extended and standard resection for pancreatic adenocarcinoma. The present study evaluated the 5-year OS and recurrence patterns according to the extent of pancreatectomy. Between 2006 and 2009, 169 consecutive patients were prospectively enrolled and randomized to standard (n = 83) or extended resection (n = 86) groups to compare 5-year OS rate, long-term recurrence patterns and factors associated with long-term survival. The surgical R0 rate was similar between the standard and extended groups (85.5 vs. 90.7%, P = 0.300). Five-year OS (18.4 vs. 14.4%, P = 0.388), 5-year disease-free survival (14.8 vs. 14.0%, P = 0.531), and overall recurrence rates (74.7 vs. 69.9%, P = 0.497) were not significantly different between the two groups, although the incidence of peritoneal seeding was higher in the extended group (25 vs. 8.1%, P = 0.014). Extended pancreatectomy does not have better short-term and long-term survival outcomes, and shows similar R0 rates and overall recurrence rates compared with standard pancreatectomy. Extended pancreatectomy does not have to be performed routinely for all cases of resectable pancreatic adenocarcinoma, especially considering its associated increased morbidity shown in our previous study. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

To determine the long-term outcomes of a prospective cohort of 20 patients who had nasopharyngectomy using an open partial-maxillectomy approach. A prospective cohort study of the surgical outcomes of patients with recurrent T1 (rT1) and rT2 nasopharyngeal carcinoma recurrence. There were 14 male and six female patients. The mean age was 49 years. The mean duration of follow-up was 60.4 months. All of the surgical margins were free of malignancy. Ten patients (50%) developed recurrences. The 5-year local control rate, disease-free, disease-specific, and overall survivals were 70%, 48.9%, 70.2%, and 66.7%, respectively. There were no major intraoperative complications. The most common morbidity was pain. The median length of hospitalization was 4 days. Early local recurrence of nasopharyngeal carcinoma can be treated surgically using a partial maxillectomy approach. The long-term outcomes are similar to nasopharyngectomy performed using the more common approaches. 4.

Executive function deficits in short-term abstinent cannabis users.

PubMed

McHale, Sue; Hunt, Nigel

2008-07-01

Few cognitive tasks are adequately sensitive to show the small decrements in performance in abstinent chronic cannabis users. In this series of three experiments we set out to demonstrate a variety of tasks that are sufficiently sensitive to show differences in visual memory, verbal memory, everyday memory and executive function between controls and cannabis users. A series of three studies explored cognitive function deficits in cannabis users (phonemic verbal fluency, visual recognition and immediate and delayed recall, and prospective memory) in short-term abstinent cannabis users. Participants were selected using snowball sampling, with cannabis users being compared to a standard control group and a tobacco-use control group. The cannabis users, compared to both control groups, had deficits on verbal fluency, visual recognition, delayed visual recall, and short- and long-interval prospective memory. There were no differences for immediate visual recall. These findings suggest that cannabis use leads to impaired executive function. Further research needs to explore the longer term impact of cannabis use. Copyright 2008 John Wiley & Sons, Ltd.

Since the 1980s, stent implantation has evolved as an important therapeutic strategy for coarctation of the aorta. However, available data is frequently flawed by short follow-up, lack of adequate follow-up imaging, and retrospective nature of data collection. Data was prospectively collected using a multicenter registry congenital cardiovascular interventional study consortium (CCISC). Between 2000 and 2009, 302 patients from 34 centers with a median weight of 58 kg underwent stent implantation for coarctation. Eligible patients (44%) completed intermediate follow-up (3-18 months) with integrated imaging (cath, CT, MRI), whereas 21% completed long-term follow-up (>18-60 months). Procedural success was defined as UL/LL systolic gradient of less than 20 mm Hg, lack of significant recurrent obstruction, and freedom from unplanned repeat intervention. Acute procedural success was 96%. Cumulative intermediate success was 86%, and cumulative long-term success was 77%. Unplanned repeat interventions were required in 4%, and aortic wall complications were seen in 1% of patients (dissection n = 1 and aneurysm n = 3). Other adverse events (n = 15) occurred mainly acutely and included technical complications such as stent malposition (n = 9). At long-term follow-up, 23% of patients continued to have systolic blood pressure above the 95th centile, 9% had an upper-to-lower limb blood pressure gradient in excess of 20 mm Hg, and 32% were taking antihypertensive medication. This study documented acute, intermediate, and long-term outcome data comparable or superior with other surgical or interventional series. However, even with successful initial stent therapy, patients continue to require long-term follow-up and have associated long-term morbidity, relating to aortic wall complications, systemic hypertension, recurrent obstruction as well as need for repeat intervention. © 2010 Wiley-Liss, Inc.

Limited studies have examined red meat consumption in relation to risk of chronic obstructive pulmonary disease (COPD), and none have examined the impact of long-term diet on COPD risk. We sought to investigate the association between long-term red meat consumption and risk of COPD. The population-based prospective Swedish Mammography Cohort included 34,053 women, aged 48-83 years, followed for the current analyses from 2002 to 2014. Unprocessed and processed red meat consumption was assessed with a self-administered questionnaire in 1987 and 1997. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Over a mean follow-up of 11.6 years (2002-2014; 393,831 person-years), 1488 COPD cases were ascertained via linkage to the Swedish health registers. A positive association between long-term processed red meat (average from 1987 to 1997) and risk of COPD was observed. In contrast, no association was observed with unprocessed red meat with corresponding HRs of 1.36 (95% CI 1.03-1.79) for processed and 0.87 (95% CI 0.74-1.02) for unprocessed red meat among women who consumed ≥ 50 g/day compared to < 25 g/day. The observed association with processed meat was confined to ex-smokers (P for interaction = 0.30); women consuming of ≥ 50 g/day of processed meat had a 2.3-fold (95% CI 1.24-4.12) higher risk of COPD than those consuming < 25 g/day. No similar associations were observed among current or never smokers. In this prospective cohort of women with moderate red meat consumption, long-term processed red meat consumption was associated with an increased risk of COPD particularly among ex-smokers.

Anterior Cervical Discectomy and Fusion Outcomes over 10 Years: A Prospective Study.

Buttermann, Glenn R

2018-02-01

Prospective cohort study with >10-year follow-up. To assess the long-term, >10-year clinical outcomes of anterior cervical discectomy and fusion (ACDF) and to compare outcomes based on primary diagnosis of disc herniation, stenosis or advanced degenerative disc disease (DDD), number of levels treated, and preexisting adjacent level degeneration. ACDF is a proven treatment for patients with stenosis and disc herniation and results in significantly improved short- and intermediate-term outcomes. Motion preservation treatments may result in improved long-term outcomes but need to be compared to long-term ACDF outcomes reference. Patients who had disc herniation, stenosis, and DDD and underwent ACDF with or without decompression were prospectively enrolled and followed for a minimum of 10 years with outcome assessment at various intervals. All 159 consecutive patients had autogenous tricortical iliac crest bone graft and plate instrumentation used. Outcomes included visual analog scale for neck and arm pain. pain drawing, Oswestry Disability Index, and self-assessment of procedure success. Preoperative adjacent-level disc degeneration, pseudarthrosis, and secondary operations were analyzed. For all diagnostic groups, significant outcomes improvement was seen at all follow-up periods for all scales relative to preoperative scores. Outcomes were not related to age, gender, number of levels treated, and minimally to preexisting degeneration at the adjacent level. The use of narcotic pain medication decreased substantially. Neurological deficits almost all resolved. Patient self-reported success ranged from 85% to 95%. Over the long term, additional surgery for pseudarthrosis (10%) occurred in the early follow-up period, and for adjacent segment degeneration (21%), which occurred linearly during the >10-year follow-up period. ACDF leads to significantly improved outcomes for all primary diagnoses and was sustained for >10 years' follow-up. Secondary surgeries were performed for pseudarthrosis repair and for symptomatic adjacent-level degeneration. 2.

Prospecting for customers in the small employer market: the experience of Arizona Health Care Group.

PubMed

Christianson, J B; Liu, C F; Schroeder, C M

1994-01-01

The findings of this study provide an interesting profile of the small employer "prospects" for prepaid health plans, where a prospect is defined as an employer that responds to a mass mailing effort with a request for information and further contact. About 60% of these prospects already have insurance, with 40% having group insurance. Therefore, a substantial portion of prospects are seeking to replace their existing health benefit package with a different one. Of those who do not offer existing insurance, the most common reason is that it is "too expensive" or the employer is "not profitable." A very small proportion do not offer insurance because they do not qualify for it due to medical underwriting considerations. Prospects tend to be larger than non-prospects in terms of sales, but employ lower wage employees, on average. About half of prospects are in service industries, a proportion typical of small employers in general. Somewhat surprisingly, most prospects have been in operation for over five years. They are not new firms attempting to establish their benefit packages. This is consistent with the findings on gross sales, suggesting that some maturity is necessary before an employer considers offering group health insurance as a benefit. The prepaid plans in this study also appeared to target established employers for their marketing efforts. In responding to questions about their attitudes towards health insurance, over one-quarter of prospects indicated that they would be unwilling to offer insurance at rates so low that they would not normally apply to the coverages offered by prepaid plans. Thus, although they were "prospects" by the study's definition, they were unlikely to eventually contract with prepaid plans. Those prospects that had offered insurance previously, but had discontinued it, tended to cite premium increases as the reason. This suggests that prospects among small employers are likely to be very price sensitive, and that further prescreening of prospects by phone, during which premium levels are discussed, might be cost-effective in following up leads from mass mailings. The study data also suggest the importance of quick follow-up for mass mailing leads, as the drop-off in recall and interest appears to be substantial. About half of the prospects interviewed stated that they were unaware of AHCG, although they or someone in their business had returned a mailer requesting more information. In addition to their implications for marketing to small employers, the results of the study appear to have broader policy implications as well.(ABSTRACT TRUNCATED AT 400 WORDS)

A Comparison of Different Methods for Evaluating Diet, Physical Activity, and Long-Term Weight Gain in 3 Prospective Cohort Studies123

Background: The insidious pace of long-term weight gain (∼1 lb/y or 0.45 kg/y) makes it difficult to study in trials; long-term prospective cohorts provide crucial evidence on its key contributors. Most previous studies have evaluated how prevalent lifestyle habits relate to future weight gain rather than to lifestyle changes, which may be more temporally and physiologically relevant. Objective: Our objective was to evaluate and compare different methodological approaches for investigating diet, physical activity (PA), and long-term weight gain. Methods: In 3 prospective cohorts (total n = 117,992), we assessed how lifestyle relates to long-term weight change (up to 24 y of follow-up) in 4-y periods by comparing 3 analytic approaches: 1) prevalent diet and PA and 4-y weight change (prevalent analysis); 2) 4-y changes in diet and PA with a 4-y weight change (change analysis); and 3) 4-y change in diet and PA with weight change in the subsequent 4 y (lagged-change analysis). We compared these approaches and evaluated the consistency across cohorts, magnitudes of associations, and biological plausibility of findings. Results: Across the 3 methods, consistent, robust, and biologically plausible associations were seen only for the change analysis. Results for prevalent or lagged-change analyses were less consistent across cohorts, smaller in magnitude, and biologically implausible. For example, for each serving of a sugar-sweetened beverage, the observed weight gain was 0.01 lb (95% CI: −0.08, 0.10) [0.005 kg (95% CI: −0.04, 0.05)] based on prevalent analysis; 0.99 lb (95% CI: 0.83, 1.16) [0.45 kg (95% CI: 0.38, 0.53)] based on change analysis; and 0.05 lb (95% CI: −0.10, 0.21) [0.02 kg (95% CI: −0.05, 0.10)] based on lagged-change analysis. Findings were similar for other foods and PA. Conclusions: Robust, consistent, and biologically plausible relations between lifestyle and long-term weight gain are seen when evaluating lifestyle changes and weight changes in discrete periods rather than in prevalent lifestyle or lagged changes. These findings inform the optimal methods for evaluating lifestyle and long-term weight gain and the potential for bias when other methods are used. PMID:26377763

The insidious pace of long-term weight gain (∼ 1 lb/y or 0.45 kg/y) makes it difficult to study in trials; long-term prospective cohorts provide crucial evidence on its key contributors. Most previous studies have evaluated how prevalent lifestyle habits relate to future weight gain rather than to lifestyle changes, which may be more temporally and physiologically relevant. Our objective was to evaluate and compare different methodological approaches for investigating diet, physical activity (PA), and long-term weight gain. In 3 prospective cohorts (total n = 117,992), we assessed how lifestyle relates to long-term weight change (up to 24 y of follow-up) in 4-y periods by comparing 3 analytic approaches: 1) prevalent diet and PA and 4-y weight change (prevalent analysis); 2) 4-y changes in diet and PA with a 4-y weight change (change analysis); and 3) 4-y change in diet and PA with weight change in the subsequent 4 y (lagged-change analysis).

To examine the relationship between the two disease-specific measures currently in use to assess swallowing outcomes following treatment in patients with head and neck cancer: the Performance Status Scale (PSS) and MD Anderson Dysphagia Inventory (MDADI). A prospective cohort study. Four head and neck cancer multidisciplinary clinics in the North of England Cancer Network. 114 patients with cancers of the upper aerodigestive tract. Measures of swallowing function administered prospectively across 4 timepoints Spearman's correlation coefficients were used to measure the relationship between the two scales. There was statistically significant correlation between the two tools at pre-treatment (rs = 0.428, P < 0.000), 3 months post-treatment (rs = 0.454, P < 0.002), 6 months post-treatment (rs = 0.551, P < 0.000) and 12 months post-treatment (rs = 0.680, P < 0.000). This is the first prospective study comparing the MDADI and PSS questionnaires at multiple time points. Our study shows that these different instruments have a good relationship in measuring swallowing function in patients with head and neck cancer in short and medium term after treatment. © 2015 John Wiley & Sons Ltd.

The prevalence of musculoskeletal pain is high among healthcare workers. Knowledge about risk factors at work is needed to efficiently target preventive strategies. This study estimates the prognosis for recovery from long-term musculoskeletal pain in different body regions among healthcare workers with different levels of perceived physical exertion during healthcare work. Prospective cohort study among 4,977 Danish female healthcare workers responding to a baseline and follow-up questionnaire in 2005 and 2006, respectively. We defined long-term pain, short-term pain and pain-free as > 30, 1-30 and 0 days with pain during the last year, and included in the analyses only those with long-term pain at baseline in the low back (N=1,089), neck/shoulder (N=1,400) and knees (N = 579), respectively. Using cumulative logistic regression analysis, the prognosis for recovering from long-term pain at baseline to short-term pain or pain-free at follow-up in the respective body regions when experiencing moderate or light (reference: strenuous) physical exertion during healthcare work was modeled. Among those with long-term pain at baseline 34% (low back), 29% (neck/shoulders), and 29% (knees) recovered to short-term pain at follow-up and 7% (low back), 8% (neck/shoulders), and 17% (knees) recovered to being pain-free. After adjusting for potential confounders (age, BMI, tenure, smoking status, leisure physical activity and psychosocial work conditions), light perceived physical exertion during healthcare work was associated with improved prognosis for recovery from long-term pain in the low back (OR 1.42, 95% CI 1.01 - 1.99) and neck/shoulders (OR 1.89, 95% CI 1.43 - 2.50), but not in the knees. Moderate physical exertion was not associated with improved prognosis for recovery from long-term pain for any of the body regions. In the present study, healthcare workers with light perceived physical exertion during healthcare work had the best prognosis for recovery from long-term pain in the low back and neck/shoulders. This suggests that efforts to reduce perceived exertion during work may improve recovery from chronic pain.

Dependence regulation in newlywed couples: A prospective examination.

According to the Risk Regulation Model (Murray, S. L., Holmes, J. G., & Collins, N. L. (2006). Optimizing assurance: The risk regulation system in relationships. Psychological Bulletin, 132 , 641-666), people need to trust in their partner's regard before they risk interdependence. The current study prospectively examines the association between perceived regard and levels of dependence in newlywed couples over nine years of marriage. Analyses demonstrate that changes in perceived regard predict levels of dependence, changes in dependence do not predict perceived regard, and alternative explanations cannot account for these effects. Further, changes in perceived regard prospectively predict divorce, and levels of dependence mediate this association. Results are discussed in terms of the dependence regulation component of the Risk Regulation Model.

Using prospective data from the Dunedin Multidisciplinary Health and Development Study birth cohort, the authors found that adolescents with low self-esteem had poorer mental and physical health, worse economic prospects, and higher levels of criminal behavior during adulthood, compared with adolescents with high self-esteem. The long-term consequences of self-esteem could not be explained by adolescent depression, gender, or socioeconomic status. Moreover, the findings held when the outcome variables were assessed using objective measures and informant reports; therefore, the findings cannot be explained by shared method variance in self-report data. The findings suggest that low self-esteem during adolescence predicts negative real-world consequences during adulthood. Copyright (c) 2006 APA, all rights reserved.

Studies have suggested associations between elevated blood pressure and short-term air pollution exposures, but the evidence is mixed regarding long-term exposures on incidence of hypertension. We examined the association of hypertension incidence with long-term residential exposures to ambient particulate matter (PM) and residential distance to roadway. We estimated 24-month and cumulative average exposures to PM10, PM2.5, and PM2.5-10 and residential distance to road for women participating in the prospective nationwide Nurses' Health Study. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for incident hypertension from 1988 to 2008 using Cox proportional hazards models adjusted for potential confounders. We considered effect modification by age, diet, diabetes, obesity, region, and latitude. Among 74,880 participants, 36,812 incident cases of hypertension were observed during 960,041 person-years. In multivariable models, 10-μg/m3 increases in 24-month average PM10, PM2.5, and PM2.5-10 were associated with small increases in the incidence of hypertension (HR: 1.02, 95% CI: 1.00, 1.04; HR: 1.04, 95% CI: 1.00, 1.07; and HR: 1.03, 95% CI: 1.00, 1.07, respectively). Associations were stronger among women < 65 years of age (HR: 1.04, 95% CI: 1.01, 1.06; HR: 1.07, 95% CI: 1.02, 1.12; and HR: 1.05, 95% CI: 1.01, 1.09, respectively) and the obese (HR: 1.07, 95% CI: 1.04, 1.12; HR: 1.15, 95% CI: 1.07, 1.23; and HR: 1.13, 95% CI: 1.07, 1.19, respectively), with p-values for interaction < 0.05 for all models except age and PM2.5-10. There was no association with roadway proximity. Long-term exposure to particulate matter was associated with small increases in risk of incident hypertension, particularly among younger women and the obese.

2016-01-01

Study Objectives: This prospective cohort study examined previously underexplored relations between psychological/social work factors and troubled sleep in order to provide practical information about specific, modifiable factors at work. Methods: A comprehensive evaluation of a range of psychological/social work factors was obtained by several designs; i.e., cross-sectional analyses at baseline and follow-up, prospective analyses with baseline predictors (T1), prospective analyses with average exposure across waves as predictor ([T1 + T2] / 2), and prospective analyses with change in exposure from baseline to follow-up as predictor. Participants consisted of a sample of Norwegian employees from a broad spectrum of occupations, who completed a questionnaire at two points in time, approximately two years apart. Cross-sectional analyses at T1 comprised 7,459 participants, cross-sectional analyses at T2 included 6,688 participants. Prospective analyses comprised a sample 5,070 of participants who responded at both T1 and T2. Univariable and multivariable ordinal logistic regressions were performed. Results: Thirteen psychological/social work factors and two aspects of troubled sleep, namely difficulties initiating sleep and disturbed sleep, were studied. Ordinal logistic regressions revealed statistically significant associations for all psychological and social work factors in at least one of the analyses. Psychological and social work factors predicted sleep problems in the short term as well as the long term. Conclusions: All work factors investigated showed statistically significant associations with both sleep items, however quantitative job demands, decision control, role conflict, and support from superior were the most robust predictors and may therefore be suitable targets of interventions aimed at improving employee sleep.

The short-term quality of life (QoL) in cervical dystonia (CD) after treating with abobotulinum toxin A (Abo-BTX A) and neubotulinum toxin A (Neu-BTX A) have been studied in Thai CD patients. However; the long-term study has not been published. The aim of the present study was to determine long-term improvement of the health-related quality of life (HRQoL) after eight injections of Abo-BTX A over 2 years in CD patients. A 2-year prospective study on the QoL of CD patients, as measured by HRQoL, before and after receiving eight injections of Abo-BTX A at 3-month intervals over a 2-year treatment period was performed. The disease-specific HRQoL was assessed before and after the treatment by using the Cervical Dystonia Impact Profile-58 (CDIP-58) questionnaire. The general HRQoL was assessed by using the Medical Outcomes 36-Item Short Form Health Survey (SF-36), while depressive disorder screening was assessed by using the Center of Epidemiologic Studies-Depression (CES-D) questionnaire. The SF-36 and CES-D questionnaire were administered before treatment and every 3 months before the next injection for a 2-year period. A total of 20 CD patients were enrolled from January 2013 to December 2015. CDIP-58 showed a significant improvement after long-term injections of Abo-BTX A in all domains ( P < 0.001). However, only vitality domain of SF-36, which assessed general HRQoL, showed a significant improvement after long-term injections ( P = 0.037). There was no prevalence of depressive disorder in all patients (CES-D score <20) in this study. The Abo-BTX A injections at 3-month intervals over a 2-year period improved the CDIP-58 scores, which assess disease-specific HRQoL, as well as an increased vitality domain of general HRQoL. No patient suffered from depression in this study.

Nonnutritive sweeteners, such as aspartame, sucralose and stevioside, are widely consumed, yet their long-term health impact is uncertain. We synthesized evidence from prospective studies to determine whether routine consumption of non-nutritive sweeteners was associated with long-term adverse cardiometabolic effects. We searched MEDLINE, Embase and Cochrane Library (inception to January 2016) for randomized controlled trials (RCTs) that evaluated interventions for nonnutritive sweeteners and prospective cohort studies that reported on consumption of non-nutritive sweeteners among adults and adolescents. The primary outcome was body mass index (BMI). Secondary outcomes included weight, obesity and other cardiometabolic end points. From 11 774 citations, we included 7 trials (1003 participants; median follow-up 6 mo) and 30 cohort studies (405 907 participants; median follow-up 10 yr). In the included RCTs, nonnutritive sweeteners had no significant effect on BMI (mean difference -0.37 kg/m 2 ; 95% confidence interval [CI] -1.10 to 0.36; I 2 9%; 242 participants). In the included cohort studies, consumption of nonnutritive sweeteners was associated with a modest increase in BMI (mean correlation 0.05, 95% CI 0.03 to 0.06; I 2 0%; 21 256 participants). Data from RCTs showed no consistent effects of nonnutritive sweeteners on other measures of body composition and reported no further secondary outcomes. In the cohort studies, consumption of nonnutritive sweeteners was associated with increases in weight and waist circumference, and higher incidence of obesity, hypertension, metabolic syndrome, type 2 diabetes and cardiovascular events. Publication bias was indicated for studies with diabetes as an outcome. Evidence from RCTs does not clearly support the intended benefits of nonnutritive sweeteners for weight management, and observational data suggest that routine intake of nonnutritive sweeteners may be associated with increased BMI and cardiometabolic risk. Further research is needed to fully characterize the long-term risks and benefits of nonnutritive sweeteners.

Traumatic brain injury is a major cause of mortality and morbidity worldwide. It can be worsened by secondary injury particularly with hypoxia or hypotension. Current prehospital guidelines emphasise regular measurement of peripheral oxygen saturation and blood pressure but there is no monitor in use to provide direct information relating to blood flow or oxygen delivery to the brain tissue. This prospective cohort study will assess the utility of near-infrared spectroscopy monitoring in prehospital medicine in demonstrating injury, pathophysiology and associations with long-term functional outcomes. A prospective cohort study will be conducted in prehospital services where physician/paramedic teams respond rapidly to patients suffering significant traumatic injuries. A study observer accompanying the clinical team will apply non-invasive near-infrared spectroscopy tissue oximetry using a Nonin EQUANOX 7610 Regional Oximetry monitor (TM Nonin Medical, Inc.). This will be applied to patients with traumatic injuries less than 30 minutes old requiring transport. Measurements will be taken at two sites on the forehead and one on the forearm. Clinical teams will be blinded to all monitoring values. Near-infrared spectroscopy tissue oximetry parameters of oxyhaemoglobin%, deoxyhaemoglobin%, total tissue haemoglobin index and regional oxygen saturation will be recorded. Separate statistical analysis relating to time spent with cerebral regional oxygen saturation values < 45% and time series analysis will be performed to demonstrate associations with acute phase outcomes including injuries seen on cerebral imaging, and long-term functional outcomes measured by Glasgow Outcome Score and Extended Glasgow Outcome Score will then be undertaken. This prospective cohort study will demonstrate associations evident from the earliest stages of prehospital treatment between near-infrared spectroscopy tissue oximetry values and both acute and long-term outcomes of patients suffering traumatic injuries. This may provide the basis for future interventional studies utilising near-infrared spectroscopy tissue oximetry to guide prehospital trauma care. This trial is registered with the Australian and New Zealand Clinical Trials Registry. The registration number is ACTRN12611001124921 .

Purpose. Published data about cryotherapy for prostate cancer (PC) treatment are based on case series with a lack of clinical trials and the inexistence of a validated definition of biochemical failure. A prospective study with standardized followup protocol was conducted in our institution. Material and Methods. Prospective study of a series of cases including 108 patients diagnosed with localized PC at clinical stage T1c-T2c treated by primary cryoablation and median followup of 61 months. Criteria of biochemical recurrence were unified according to the American Society for Therapeutic Radiology and Oncology (ASTRO). End points were biochemical progression-free survival (BPFS), cancer-specific survival, and overall survival. Rate of complications was reported. Results. The BPFS for low-, medium-, and high-risk patients was 96.4%, 91.2%, and 62.2%, respectively. Cancer-specific survival was 98.1%. Overall survival reached 94.4%. Complications included incontinence in 5.6%, urinary tract obstruction in 1.9%, urethral sloughing in 5.6%, haematuria in 1.9%, perineal pain in 11.1%, and prostatorectal fistula in 0.9%. Erectile disfunction was found in 98.1%. Conclusions. Cryotherapy is an effective and minimally invasive treatment for primary PC in well-selected cases, with low surgical risk and good results in terms of BPFS, cancer-specific survival, and overall survival.

Transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) has been associated with improved long-term dysphagia symptomatology compared with chemoradiation. Dysphagia in the perioperative period has been inadequately characterized. The objective of this study was to characterize short-term swallowing outcomes after TORS for OPSCC. Patients undergoing TORS for OPSCC were enrolled prospectively. The Eating Assessment Tool 10 (EAT-10) was used as a measure of swallowing dysfunction (score >2) and was administered on postoperative day (POD) 1, 7, and 30. Patient demographics, weight, pain level, and clinical outcomes were recorded prospectively and focused on time to oral diet, feeding tube placement, and dysphagia-related readmissions. A total of 51 patients were included with pathologic T stages of T1 (n = 24), T2 (n = 20), T3 (n = 3), and Tx (n = 4). Self-reported preoperative dysphagia was unusual (13.7%). The mean EAT-10 score on POD 1 was lower than on POD 7 (21.5 vs 26.6; P = .005) but decreased by POD 30 (26.1 to 12.2; P < .001). Forty-seven (92.1%) patients were discharged on an oral diet, but 57.4% required compensatory strategies or modification of liquid consistency. Ninety-eight percent of patients were taking an oral diet by POD 30. There were no dysphagia-related readmissions. This prospective study shows that most patients who undergo TORS experience dysphagia for at least the first month postoperatively, but nearly all can be started on an oral diet. The dysphagia-associated complication profile is acceptable after TORS with a minority of patients requiring temporary feeding tube placement. Aggressive evaluation and management of postoperative dysphagia in TORS patients may help prevent dysphagia-associated readmissions.

To describe current efforts and future potential for understanding long-term health of military service members by linking the Millennium Cohort Study data to exposures and health outcomes. The Millennium Cohort Study launched in 2001, before September 11 and the start of combat operations in Afghanistan and Iraq. Other substantial Department of Defense (DoD) health, personnel, and exposure databases are maintained in electronic form and may be linked by personal identifiers. More than 150,000 consenting members comprise the Millennium Cohort from all services, and include active duty, Reserve, and National Guard current and past members, and represent demographic, occupational, military, and health characteristics of the U.S. military. These prospective data offer symptom assessment, behavioral health, and self-reported exposures that may complement and fill gaps in capability presented by other DoD electronic health and exposure data. In conjunction with Millennium Cohort survey data, prospective individual-level exposure and health outcome assessment is crucial to understand and quantify any long-term health outcomes potentially associated with unique military occupational exposures.

Epidemiologic studies of red meat consumption in relation to risk of heart failure (HF) are limited. We examined the associations between long-term unprocessed red meat and processed red meat consumption and incidence of HF in women. The population-based prospective Swedish Mammography Cohort included 34,057 women, aged 48-83 years, with no history of HF or ischemic heart disease at baseline (in 1997). Meat consumption was assessed using a self-administered food-frequency questionnaire (FFQ) in 1997 as well as FFQ administered in 1987-90. Cox proportional hazard regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). During a mean follow-up of 13.2 years, 2806 women were diagnosed with HF. Consumption of processed meat (FFQ 1997) was statistically significant positively associated with HF incidence. Women who consumed ≥ 50 g/day processed red meat compared to those who consumed < 25 g/day had a 1.23 (95% CI: 1.09-1.39, P-trend=0.003) higher risk of HF. Long-term high consumption of processed red meat (average from 1987 to 1997) ≥ 50 g/day in comparison to < 25 g/day was associated with HR: 1.30 (95% CI: 1.05-1.60, P-trend=0.002). Women who consistently consumed (in both 1987 and 1997) ≥ 50 g/day vs. < 25 g/day had a 1.78 (95% CI: 1.00-3.16) higher risk of HF. Consumption of unprocessed meat was not associated with increased risk of HF incidence.

Atrial fibrillation recurrence after pulmonary vein (PV) isolation is associated with PV to left atrium reconduction. We prospectively studied the use of 2 procedural techniques designed to facilitate identification of residual gaps within the index ablation line. After wide circumferential PV isolation, 40 patients received additional ablation targeted at locations of left atrial capture during high-output pacing (pace-capture group), while 40 patients underwent adenosine testing with targeted ablation at sites of dormant conduction (adenosine group). Patients were followed up at 3, 6, and 12 months. After PV isolation, high-output pace-capture was documented in 39 PVs (25%; 50% of patients) in the pace-capture group. Dormant conduction was unmasked in 34 PVs (22%; 53% of patients) in the adenosine group. A subset of 25 patients in the pace-capture group underwent adenosine testing without targeted ablation of dormant conduction. In these patients, only 10 out of 86 PVs (11.6%; 24% of patients) demonstrated dormant conduction after the elimination of local pace-capture. At a follow-up of 329±124 days, the single procedure off antiarrhythmic drug freedom from recurrent atrial fibrillation was 67.5% in the adenosine group and 65.0% in the pace-capture group (P=0.814). Procedure duration and fluoroscopy time were significantly longer in the pace-capture group (P=0.002 and P<0.001), whereas radiofrequency ablation time was comparable (P=0.192). The use of high-output pacing post-PV isolation results in a significant reduction in the incidence of dormant conduction with a comparable long-term freedom from recurrent atrial fibrillation (versus adenosine-guided ablation). The use of these approaches requires evaluation in a long-term prospective randomized study. [corrected].

Compositional Variation of Tourmaline from the Paleoproterozoic Bhukia Gold Prospect of Aravalli Supergroup, Western India: Implications for the Provenance and Gold Metallogeny

Bhukia is a unique gold prospect in terms of its host lithologies such as albitite and carbonates with respect to greenstone hosted Archean gold deposits from India. Tourmaline occurs along with apatite, magnetite, graphite, chalcopyrite and gold-sulfide association in Bhukia gold prospect preserve geochemical record of changing physico-chemical conditions during its growth. Tourmalinization is one of the distinct hydrothermal alterations present in the study area. Chemical composition of two varieties of tourmalines presents as significant amounts within albitite and carbonate rocks from Bhukia gold prospect. EPMA analysis of two varieties of tourmalines viz. 1) rounded to sub-rounded, euhedral, green colored tourmalines and 2) elongated, zoned, brown colored tourmalines unlocks their chemical compositions as well as variations from core to rim. In some albitite litho-units, tourmaline occurs as major constituents (>15%), present as layers, termed as tourmalinites. Al-Fe-Mg and Na/ (Na+Ca) vs Fe/ (Fe+Mg) suggests that tourmalines from the Bhukia gold prospect are Mg-rich dravite to Fe-rich schrol in composition. Tourmalines present within the albitite rocks show variations in iron and sodium content from core to rim whereas similarity exist from core to rim in case of carbonate rocks. Presence of albite confirms the role of Na-rich fluids during the formation of tourmalines. Tourmalines present in Bhukia gold prospect is mainly influenced by boron influx and the source may be boron bearing hydrothermal fluid or boron bearing minerals. Dewatering of original un-metamorphosed rock during progressive metamorphism may remove boron from the metasedimentary rocks. Due to the mobile nature of boron, it dispersed and mixed with hydrothermal fluids and alumina that is required for the formation of the tourmaline might have been leached from metasedimentary rocks present in Bhukia gold prospect. Presence of hydrothermal alterations such as tourmalinization and albitization along with Au-Cu-graphite-magnetite association suggest this deposit to be an IOCG (Iron oxide copper gold) type.

BACKGROUND: Among the numerous studies concerning contrast media-induced nephropathy (CIN), there was no prospective trial that provided data on the long-term outcomes. OBJECTIVES: To prospectively assess predictors of CIN and long-term outcomes of affected patients. METHODS: Four hundred twelve consecutive patients with serum creatinine levels of 115 μmol/L to 309 μmol/L (1.3 mg/dL to 3.5 mg/dL) undergoing elective coronary angiography were included. Patients were randomly assigned to periprocedural hydration alone, hydration plus onetime hemodialysis or hydration plus N-acetylcysteine. RESULTS: Multivariate logistic regression identified the following as predictors of CIN within 72 h (equivalent to an increase in creatinine 44.2 μmol/L [0.5 mg/dL] or more) : prophylactic postprocedural hemodialysis (OR 2.86, 95% CI 1.07 to 7.69), use of angiotensin-converting enzyme inhibitors (OR 6.16, 95% CI 2.01 to 18.93), baseline glomerular filtration rate (OR 0.94, 95% CI 0.90 to 0.98) and the amount of contrast media given (OR 1.01, 95% CI 1.00 to 1.01). With regard to long-term outcome (mean follow-up 649 days), multivariate Cox regression models found elevated creatinine levels at 30 days (hazard rate ratio [HRR] 5.48, 95% CI 2.85 to 10.53), but not CIN within 72 h (HRR 1.12, 95% CI 0.63 to 2.02), to be associated with increased mortality. In addition, independent predictors for death during follow-up included left ventricular ejection fraction lower than 35% (HRR 4.01, 95% CI 2.22 to 7.26), serum phosphate (HRR 1.64, 95% CI 1.10 to 2.43) and hemoglobin (HRR 0.80, 95% CI 0.67 to 0.96). CONCLUSION: From the present prospective trial, performance of post-procedural hemodialysis, use of angiotensin-converting enzyme inhibitors, reduced baseline glomerular filtration rate and amount of contrast media were independent predictors of CIN within 72 h after catheterization. Assessing renal function after 30 days, rather than within 72 h, seemed to be more predictive for patients’ long-term survival. PMID:18987758

Increasing studies suggest the importance of including prospective memory measures in clinical evaluation of dementia due to its sensitivity and functional relevance. The Prospective and Retrospective Memory Questionnaire (PRQM) is originally a self-rated memory inventory that offers a direct comparison between prospective and episodic memory. However, the informant's report has been recognized as a more valid source of cognitive complaints. We thus aimed to examine the validity of the informant-rated form of the PRMQ in assessing memory function of the patients and in detecting individuals with early dementia. The informants of 140 neurological outpatients with memory complaints completed the Taiwan version of the PRMQ. Tests of prospective memory, short-term memory, and general cognitive ability were also administered to non-demented participants and patients with early stages of Alzheimer's disease (AD). Results showed significant relationships between the PRMQ ratings and objective cognitive measures, and showed that higher ratings on the PRMQ were associated with increasing odds of greater dementia severity. Receiver operative characteristic (ROC) curves showed an adequate ability of the PRMQ to identify patients with dementia (93% sensitivity and 84% specificity). Hierarchical regression revealed that the PRMQ has additional explanatory power for dementia status after controlling for age, education and objective memory test results, and that the prospective memory subscale owns predictive value for dementia beyond the retrospective memory subscale. The present study demonstrated the external validity and diagnostic value of informants' evaluation of their respective patients' prospective and retrospective memory functioning, and highlighted the important role of prospective memory in early dementia detection. The proxy-version of the PRMQ is a useful tool that captures prospective and episodic memory problems in patients with early AD, in combination with standardized cognitive testing. PMID:25383950

Background: Acute Coronary Syndrome (ACS) is increasing in Yemen in recent years and there are no data available on its short and long-term outcome. We evaluated the clinical pictures, management, in-hospital, and long-term outcomes of the ACS patients in Yemen. Design and Setting: A 9-month prospective, multi-center study conducted in 26 hospitals from 9 governorates. The study included 30-day and 1-year mortality follow-up. Patients and Methods: One thousand seven hundred and sixty one patients with ACS were collected prospectively during the 9-month period. Patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation acute coronary syndrome (NSTEACS), including non-ST-elevation myocardial infarction and unstable angina were included. Conclusions: ACS patients in Yemen present at a relatively young age with high prevalence of Smoking, khat chewing and hypertension. STEMI patients present late, and their acute management is poor. In-hospital evidence-based medication rates are high, but coronary revascularization procedures were very low. In-hospital mortality was high and long-term mortality rates increased two folds compared with the in-hospital mortality. PMID:24695681

To clarify whether distinguishing between the uterine isthmus and cervix can improve the accuracy of diagnosing placenta previa at term. A multicenter prospective observational study was conducted among pregnant women with suspected placenta previa at 20-24 weeks' gestation. Subjects were divided into the open isthmus group and closed isthmus group. The accuracy of diagnosing placenta previa at term was compared between the 2 groups. We screened 9,341 patients, and 53 (0.6%) met the inclusion criteria. Nineteen cases with an open isthmus and 34 with a closed isthmus were followed. The accuracy for diagnosing placenta previa or a low-lying placenta at term was 94.7% in the open isthmus group and 26.5% in the closed isthmus group (p < 0.001). Elective or emergency Cesarean section was required in 100% of cases in the open isthmus group and 20.6% in the closed isthmus group (p < 0.001). A high prediction rate of placenta previa was obtained by using transvaginal ultrasound at 20-24 weeks' gestation after the isthmus opened by carefully distinguishing between the cervix and isthmus. © 2016 S.

Biodegradable magnesium-based screw clinically equivalent to titanium screw in hallux valgus surgery: short term results of the first prospective, randomized, controlled clinical pilot study

PubMed Central

2013-01-01

Purpose Nondegradable steel-and titanium-based implants are commonly used in orthopedic surgery. Although they provide maximal stability, they are also associated with interference on imaging modalities, may induce stress shielding, and additional explantation procedures may be necessary. Alternatively, degradable polymer implants are mechanically weaker and induce foreign body reactions. Degradable magnesium-based stents are currently being investigated in clinical trials for use in cardiovascular medicine. The magnesium alloy MgYREZr demonstrates good biocompatibility and osteoconductive properties. The aim of this prospective, randomized, clinical pilot trial was to determine if magnesium-based MgYREZr screws are equivalent to standard titanium screws for fixation during chevron osteotomy in patients with a mild hallux valgus. Methods Patients (n=26) were randomly assigned to undergo osteosynthesis using either titanium or degradable magnesium-based implants of the same design. The 6 month follow-up period included clinical, laboratory, and radiographic assessments. Results No significant differences were found in terms of the American Orthopaedic Foot and Ankle Society (AOFAS) score for hallux, visual analog scale for pain assessment, or range of motion (ROM) of the first metatarsophalangeal joint (MTPJ). No foreign body reactions, osteolysis, or systemic inflammatory reactions were detected. The groups were not significantly different in terms of radiographic or laboratory results. Conclusion The radiographic and clinical results of this prospective controlled study demonstrate that degradable magnesium-based screws are equivalent to titanium screws for the treatment of mild hallux valgus deformities.

The research explored the effects of 45-day -6° head-down bed rest (HDBR) simulation of microgravity on the time-based prospective memory (PM) with 16 males. The time-based prospective memory task was performed on the 2nd day before HDBR, on the 11th, 20th, 32nd, and 40th days during HDBR, and on the 8th day after HDBR, and subjects' anxiety and depression feelings were recorded simultaneously using Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). The results demonstrated that it showed decreased accuracy of PM responses and frequency of clock checks during and after bed rest; long term bed rest did not induce significant emotional changes. The deficit of prospective memory performance induced by long term HDBR may result from a lack of aerobic physical activity or changes in the prefrontal cortex, but it remains to be determined.

To evaluate the clinical outcomes of high-intensity focused ultrasound (HIFU) and surgery in treating uterine fibroids, and prepare for a definitive randomised trial. Prospective multicentre patient choice cohort study (IDEAL Exploratory study) of HIFU, myomectomy or hysterectomy for treating symptomatic uterine fibroids. 20 Chinese hospitals. 2411 Chinese women with symptomatic fibroids. Prospective non-randomised cohort study with learning curve analysis (IDEAL Stage 2b Prospective Exploration Study). Complications, hospital stay, return to normal activities, and quality of life (measured with UFS-Qol and SF-36 at baseline, 6 and 12 months), and need for further treatment. Quality-of-life outcomes were adjusted using regression modelling. HIFU treatment quality was evaluated using LC-CUSUM to identify operator learning curves. A health economic analysis of costs was performed. 1353 women received HIFU, 472 hysterectomy and 586 myomectomy. HIFU patients were significantly younger (P < 0.001), slimmer (P < 0.001), better educated (P < 0.001), and wealthier (P = 0.002) than surgery patients. Both UFS and QoL improved more rapidly after HIFU than after surgery (P = 0.002 and P = 0.001, respectively at 6 months), but absolute differences were small. Major adverse events occurred in 3 (0.2%) of HIFU and in 133 (12.6%) of surgical cases (P < 0.001). Median time for hospital stay was 4 days (interquartile range, 0-5 days), 10 days (interquartile range, 8-12.5 days) and 8 days (interquartile range, 7-10 days). HIFU caused substantially less morbidity than surgery, with similar longer-term QoL. Despite group baseline differences and lack of blinding, these findings support the need for a randomised controlled trial (RCT) of HIFU treatment for fibroids. The IDEAL Exploratory design facilitated RCT protocol development. HIFU had much better short-term outcomes than surgery for fibroids in 2411-patient Chinese IDEAL format study. © 2017 Royal College of Obstetricians and Gynaecologists.

In the literature, studies of computer-assisted total knee arthroplasty (TKA) after mid-term period are not conclusive and long-term data are rare. In a prospective, randomized, comparative study 100 conventional TKAs (group REG) were compared with 100 computer-assisted TKAs (group NAV). Minimum follow-up was 5years. No difference in implant failure was found with 1.1% in group NAV versus 4.6% in group REG (P=0.368). Group NAV showed a significantly less mean deviation of mechanical limb axis (P=0.015), more TKAs (90% versus 81% in group REG) were within 3° varus/valgus and a higher tibial slope and lateral distal femoral angle (LDFA) accuracy was found (P≤0.034). Clinical investigational parameters showed no differences (P≥0.058). Insall and HSS score total were also higher in group NAV (P≤0.016). Copyright © 2014 Elsevier Inc. All rights reserved.

Safety of vedolizumab in the treatment of Crohn's disease and ulcerative colitis.

Hagan, Matilda; Cross, Raymond K

2015-01-01

Vedolizumab is the latest FDA-approved anti-integrin therapy for treatment of moderate-to-severe inflammatory bowel disease (IBD). The safety and efficacy of vedolizumab have been studied in short-term clinical trials. This paper reviews the safety profile of vedolizumab compared with other biologics. It also highlights the mechanism of action of the medication. We discuss the current position of vedolizumab in our current algorithm for IBD management and comment on future prospects of the drug. Vedolizumab appears to be a safe and effective option in the treatment of moderate-to-severe IBD in the short term. Long-term observational studies and post-marketing safety data are needed to ascertain the long-term efficacy and side effect profile.

This study evaluated the short-term safety and feasibility of epiretinal strontium-90 brachytherapy delivered concomitantly with intravitreal bevacizumab for the treatment of subfoveal CNV due to AMD for 12 months. A 3-year follow-up is planned. In this prospective, non-randomised, multicentre study, 34 treatment-naïve patients with predominantly classic, minimally classic and occult subfoveal CNV lesions received a single treatment with 24 Gy beta radiation (strontium-90) and two injections of the anti-VEGF antibody bevacizumab. Adverse events were observed. BCVA was measured using standard ETDRS vision charts. Twelve months after treatment, no radiation-associated adverse events were observed. In the intent-to-treat (ITT) population, 91% of patients lost <3 lines (15 ETDRS letters) of vision at 12 months, 68% improved or maintained their BCVA at 12 months, and 38% gained >/=3 lines. The mean change in BCVA observed at month 12 was a gain of 8.9 letters. The safety and efficacy of intraocular, epiretinal brachytherapy delivered concomitantly with anti-VEGF therapy for the treatment of subfoveal CNV secondary to AMD were promising in this small study population. Long-term safety will be assessed for 3 years. This regimen is being evaluated in a large, multicentre, phase III study.

Longman, R J; Thomson, W H F

2006-02-01

With the recent introduction of stapled anopexy it is timely to review the benefits of existing treatment options for piles. This study investigates the effectiveness and safety of rubber band ligation (RBL) of piles in the outpatient setting. Two hundred and fifty-two consecutive patients referred with piles in an 18-month period were studied prospectively. In those patients deemed suitable for banding of piles, data were collected on symptoms, proctoscopic appearance and degree of piles. Short and long-term outcome data were recorded for success of treatment and complications. Of 203 patients considered suitable and who attended for RBL, 176 kept their follow-up appointment. One hundred and forty-eight (84%) had been rendered symptom-free. A third of patients, however, had proctoscopic evidence of persistent piles, whilst in half of those patients with continuing symptoms the anal cushions appeared normal. Six (3%) patients had suffered a complication. Long-term follow-up by questionnaire found that 44% of respondents remained asymptomatic at a median of 46 months from banding. Six (5%) of 117 responders to the questionnaire had, though previously normal, suffered a postbanding impairment of continence. Most patients with piles of any degree can be safely managed by rubber band ligation, but return of symptoms in the long term affects more than half of patients treated.

Review: long-term impact of bariatric surgery on body weight, comorbidities, and nutritional status.

Shah, Meena; Simha, Vinaya; Garg, Abhimanyu

2006-11-01

The number of patients who undergo Roux-en-Y gastric bypass (RYGB) and gastric banding (GB) surgeries has increased dramatically over the past decade, yet the long-term impact of these surgeries on body weight, comorbidities, and nutritional status remains unclear, as do the mechanisms of weight regain. The articles were found via PubMed searches. To review the impact of bariatric surgery on weight maintenance and comorbidities, only articles with a postoperative follow-up of 3 yr or longer were included. The articles on nutritional status had a follow-up of 12 months or longer. RYGB and GB surgeries lead to substantial weight loss in individuals with morbid obesity. However, significant weight regain occurs over the long term, and according to the only well-designed prospective controlled study, the improvement in comorbidities associated with weight loss mitigates in the long term on weight regain. There is some evidence from a retrospective study that RYGB surgery is associated with a modest decrease in long-term mortality. These results remain to be substantiated by well-designed, long-term, randomized and prospective controlled studies. The mechanisms that lead to weight regain need to be further examined and may include increase in energy intake due to enlargement of stoma and adaptive changes in the levels of gut and adipocyte hormones such as ghrelin and leptin, which regulate energy intake; decrease in physical activity; changes in energy expenditure; and other factors. In addition to weight regain, RYGB surgery is associated with frequent incidence of iron, vitamin B12, folate, calcium, and vitamin D deficiency, which requires regular supplementation and monitoring.

In this study, the effect on the achievement and attitudes of prospective teachers is examined. With this aim ahead, achievement test, attitude scale for statistics and interviews were used as data collection tools. The achievement test comprises 8 problems based on statistical data, and the attitude scale comprises 13 Likert-type items. The study was carried out in 2014-2015 academic year fall semester at a university in Turkey. The study, which employed the pre-test-post-test control group design of quasi-experimental research method, was carried out on a group of 80 prospective teachers, 40 in the control group and 40 in the experimental group. Both groups had four-hour classes about descriptive statistics. The classes with the control group were carried out through traditional methods while dynamic statistics software was used in the experimental group. Five prospective teachers from the experimental group were interviewed clinically after the application for a deeper examination of their views about application. Qualitative data gained are presented under various themes. At the end of the study, it was found that there is a significant difference in favour of the experimental group in terms of achievement and attitudes, the prospective teachers have affirmative approach to the use of dynamic software and see it as an effective tool to enrich maths classes. In accordance with the findings of the study, it is suggested that dynamic software, which offers unique opportunities, be used in classes by teachers and students.

Long-term risks of kidney living donation: review and position paper by the ERA-EDTA DESCARTES working group.

Two recent matched cohort studies from the USA and Norway published in 2014 have raised some concerns related to the long-term safety of kidney living donation. Further studies on the long-term risks of living donation have since been published. In this position paper, Developing Education Science and Care for Renal Transplantation in European States (DESCARTES) board members critically review the literature in an effort to summarize the current knowledge concerning long-term risks of kidney living donation to help physicians for decision-making purposes and for providing information to the prospective live donors. Long-term risk of end-stage renal disease (ESRD) can be partially foreseen by trying to identify donors at risk of developing ‘de novo’ kidney diseases during life post-donation and by predicting lifetime ESRD risk. However, lifetime risk may be difficult to assess in young donors, especially in those having first-degree relatives with ESRD. The study from Norway also found an increased risk of death after living donor nephrectomy, which became visible only after >15 years of post-donation follow-up. However, these findings are likely to be largely the result of an overestimation due to the confounding effect related to a family history of renal disease. DESCARTES board members emphasize the importance of optimal risk–benefit assessment and proper information to the prospective donor, which should also include recommendations on health-promoting behaviour post-donation. © The Author 2017.

The aim of this study was to evaluate the efficacy and safety of fractional carbon dioxide laser for the treatment of acne scars. Thirty-one participants, 15 female and 16 male, whose mean age was 34.84 ± 10.94 years, were included in this prospective study. The study took place between 2012 and 2016. Participants were evaluated with the "ECCA Grading Scale" before the first session, 3 months (short-term evaluation) and 3 years after the last session (long-term evaluation). Participants received two or three treatment sessions at 4-week intervals, with a 10,600 nm fractional carbon dioxide laser with pulse energies ranging between 100 and 160 mJ, 120 spot type, 75-100 spot/cm 2 density, and 30 W power. Self-assessments by the participants were done 3 months and 3 years after the last session. The mean ECCA score was 107.90 ± 39.38 before the first session, and 82.17 ± 36.23 at the time of short-term evaluation (p = 0.000). The grade of improvement at the short-term evaluation was as follows: no improvement, mild, moderate, and significant improvement for 7 (22.6%), 11 (35.5%), 9 (29%), and 4 (12.9%) of the participants, respectively. Regarding self-assessments, 80.6 and 61.3% of the participants rated themselves as having at least mild improvement at the short-term and the long-term follow-up periods, respectively. The results of this study suggest that fractional carbon dioxide laser is an efficient treatment option for acne scars. Furthermore, self-assessment results show that more than half of the participants still experience at least mild improvement at the end of 3 years.

The present review discusses the current state of research on the clinical neuropsychology of prospective memory in Parkinson's disease. To do so the paper is divided in two sections. In the first section, we briefly outline key features of the (partly implicit) rationale underlying the available literature on the clinical neuropsychology of prospective memory. Here, we present a conceptual model that guides our approach to the clinical neuropsychology of prospective memory in general and to the effects of Parkinson's disease on prospective memory in particular. In the second section, we use this model to guide our review of the available literature and suggest some open issues and future directions motivated by previous findings and the proposed conceptual model. The review suggests that certain phases of the prospective memory process (intention formation und initiation) are particularly impaired by Parkinson's disease. In addition, it is argued that prospective memory may be preserved when tasks involve specific features (e.g., focal cues) that reduce the need for strategic monitoring processes. In terms of suggestions for future directions, it is noted that intervention studies are needed which target the specific phases of the prospective memory process that are impaired in Parkinson's disease, such as planning interventions. Moreover, it is proposed that prospective memory deficits in Parkinson's disease should be explored in the context of a general impairment in the ability to form an intention and plan or coordinate an appropriate series of actions.

Introduction Young people with drug and alcohol problems are likely to have poorer health and other psychosocial outcomes than other young people. Residential treatment programmes have been shown to lead to improved health and related outcomes for young people in the short term. There is very little robust research showing longer term outcomes or benefits of such programmes. This paper describes an innovative protocol to examine the longer term outcomes and experiences of young people referred to a residential life management and treatment programme in Australia designed to address alcohol and drug issues in a holistic manner. Methods and analysis This is a mixed-methods study that will retrospectively and prospectively examine young people's pathways into and out of a residential life management programme. The study involves 3 components: (1) retrospective data linkage of programme data to health and criminal justice administrative data sets, (2) prospective cohort (using existing programme baseline data and a follow-up survey) and (3) qualitative in-depth interviews with a subsample of the prospective cohort. The study will compare findings among young people who are referred and (a) stay 30 days or more in the programme (including those who go on to continuing care and those who do not); (b) start, but stay fewer than 30 days in the programme; (c) are assessed, but do not start the programme. Ethics and dissemination Ethics approval has been sought from several ethics committees including a university ethics committee, state health departments and an Aboriginal-specific ethics committee. The results of the study will be published in peer-reviewed journals, presented at research conferences, disseminated via a report for the general public and through Facebook communications. The study will inform the field more broadly about the value of different methods in evaluating programmes and examining the pathways and trajectories of vulnerable young people. PMID:27225650

Increased intake of dietary fiber has been proposed to reduce the risk of inflammatory bowel disease (Crohn's disease [CD] and ulcerative colitis [UC]). However, few prospective studies have examined associations between long-term intake of dietary fiber and risk of incident CD or UC. We collected and analyzed data from 170,776 women, followed up over 26 years, who participated in the Nurses' Health Study, followed up for 3,317,425 person-years. Dietary information was prospectively ascertained via administration of a validated semiquantitative food frequency questionnaire every 4 years. Self-reported CD and UC were confirmed through review of medical records. Cox proportional hazards models, adjusting for potential confounders, were used to calculate hazard ratios (HRs). We confirmed 269 incident cases of CD (incidence, 8/100,000 person-years) and 338 cases of UC (incidence, 10/100,000 person-years). Compared with the lowest quintile of energy-adjusted cumulative average intake of dietary fiber, intake of the highest quintile (median of 24.3 g/day) was associated with a 40% reduction in risk of CD (multivariate HR for CD, 0.59; 95% confidence interval, 0.39-0.90). This apparent reduction appeared to be greatest for fiber derived from fruits; fiber from cereals, whole grains, or legumes did not modify risk. In contrast, neither total intake of dietary fiber (multivariate HR, 0.82; 95% confidence interval, 0.58-1.17) nor intake of fiber from specific sources appeared to be significantly associated with risk of UC. Based on data from the Nurses' Health Study, long-term intake of dietary fiber, particularly from fruit, is associated with lower risk of CD but not UC. Further studies are needed to determine the mechanisms that mediate this association. Copyright © 2013 AGA Institute. Published by Elsevier Inc. All rights reserved.

Study Objectives: Impaired sleep is an established risk factor for the development of cardiovascular disease, whereas less is known about how impaired sleep affects cardiovascular prognosis. The aim of this study is to determine how different aspects of impaired sleep affect the risk of case fatality and subsequent cardiovascular events following first-time acute myocardial infarction (AMI). Design: Prospective cohort study. Setting: The Stockholm Heart Epidemiology Program, Sweden. Participants: There were 2,246 first-time AMI cases. Measurements and Results: Sleep impairment was assessed by the Karolina Sleep Questionnaire, which covers various indices of impaired sleep: disturbed sleep, impaired awakening, daytime sleepiness, and nightmares. Case fatality, defined as death within 28 days of initial AMI, and new cardiovascular events within up to 10 y of follow-up were identified through national registries. In women, disturbed sleep showed a consistently higher risk of long-term cardiovascular events: AMI (hazard ratio [HR] = 1.69; 95% confidence interval [CI] 0.95–3.00), stroke (HR = 2.61; 95% CI: 1.19–5.76), and heart failure (HR = 2.43; 95% CI: 1.18–4.97), whereas no clear effect of impaired sleep on case fatality was found in women. In men, a strong effect on case fatality (odds ratio = 3.27; 95% CI: 1.76–6.06) was observed in regard to impaired awakening; however, no consistent effect of impaired sleep was seen on long-term cardiovascular prognosis. Conclusion: Results suggest sex-specific effects of impaired sleep that differ by short- and long-term prognosis. Sleep complaints are frequent, easily recognizable, and potentially manageable. Evaluation of sleep complaints may, even if they represent prognostic markers rather than risk factors, provide additional information in clinical risk assessment that could benefit secondary cardiovascular prevention.

Lactoferricin and lactoferrampin, peptides derived from the whey protein lactoferrin, are antimicrobial agents with a promising prospect and are currently one of the research focuses. In this review, a basic introduction including location and solution structures of these two peptides is given. Their biological activities encompassing antiviral, antibacterial, antifungal and anti-inflammatory activities with possible mechanisms are mentioned. In terms of modification studies, research about identification of their active derivatives and crucial amino acid residues is also discussed. Various attempts at modification of lactoferricin and lactoferrampin such as introducing big hydrophobic side-chains; employing special amino acids for synthesis; N-acetylization, amidation, cyclization and peptide chimera are summarized. The studies on lactoferricin-lactoferrampin chimera are discussed in detail. Future prospects of lactoferricin and lactoferrampin are covered.

The role of physical activity in producing and maintaining weight loss

Catenacci, Victoria A; Wyatt, Holly R

2015-01-01

Summary The majority of randomized, controlled trials (RCTs) show only modest weight loss with exercise intervention alone, and slight increases in weight loss when exercise intervention is added to dietary restriction. In most RCTs, the energy deficit produced by the prescribed exercise is far smaller than that usually produced by dietary restriction. In prospective studies that prescribed high levels of exercise, enrolled individuals achieved substantially greater weight loss—comparable to that obtained after similar energy deficits were produced by caloric restriction. High levels of exercise might, however, be difficult for overweight or obese adults to achieve and sustain. RCTs examining exercise and its effect on weight-loss maintenance demonstrated mixed results; however, weight maintenance interventions were usually of limited duration and long-term adherence to exercise was problematic. Epidemiologic, cross-sectional, and prospective correlation studies suggest an essential role for physical activity in weight-loss maintenance, and post hoc analysis of prospective trials shows a clear dose–response relationship between physical activity and weight maintenance. This article reviews the role of physical activity in producing and maintaining weight loss. We focus on prospective, RCTs lasting at least 4 months; however, other prospective trials, meta-analyses and large systematic reviews are included. Limitations in the current body of literature are discussed. PMID:17581621

Study Design Study protocol for a randomized controlled trial and a prospective cohort. Background The number of arthroscopic surgical procedures for patients with femoroacetabular impingement syndrome (FAIS) has significantly increased worldwide, but high-quality evidence of the effect of such interventions is lacking. Objectives The primary objective will be to determine the efficacy of hip arthroscopic procedures compared to sham surgery on patient-reported outcomes for patients with FAIS (HIP ARThroscopy International [HIPARTI] Study). The secondary objective will be to evaluate prognostic factors for long-term outcome after arthroscopic surgical interventions in patients with FAIS (Hip ARthroscopy Prospective [HARP] Study). Methods The HIPARTI Study will include 140 patients and the HARP Study will include 100 patients. The international Hip Outcome Tool-33 will be the primary outcome measure at 1 year. Secondary outcome measures will be the Hip disability and Osteoarthritis Outcome Score, Arthritis Self-Efficacy Scale, fear of movement (Tampa Scale of Kinesiophobia), Patient-Specific Functional Scale, global rating of change score, and expectations. Other outcomes will include active hip range of motion, hip muscle strength tests, functional performance tests, as well as radiological assessments using radiographs and magnetic resonance imaging. Conclusion To determine the true effect of surgery, beyond that of placebo, double-blinded placebo-controlled trials including sham surgery are needed. The HIPARTI Study will direct future evidence-based treatment of FAIS. Predictors for long-term development and progression of degenerative changes in the hip are also needed for this young patient group with FAIS; hence, responders and nonresponders to treatment could be determined.

We conducted a randomised prospective study to evaluate the clinical and radiological results of a mobile- and fixed-bearing total knee replacement of similar design in 174 patients who had bilateral simultaneous knee replacement. The mean follow-up was for 5.6 years (5.2 to 6.1). The total knee score, pain score, functional score and range of movement were not statistically different (p > 0.05) between the two groups. Osteolysis was not seen in any knee in either group. Two knees (1%) in the mobile-bearing group required revision because of infection; none in the fixed-bearing group needed revision. Excellent results can be achieved with both mobile- and fixed-bearing prostheses of similar design at mid-term follow-up. We could demonstrate no significant clinical advantage for a mobile bearing.

Temporal production and visuospatial processing.

PubMed

Benuzzi, Francesca; Basso, Gianpaolo; Nichelli, Paolo

2005-12-01

Current models of prospective timing hypothesize that estimated duration is influenced either by the attentional load or by the short-term memory requirements of a concurrent nontemporal task. In the present study, we addressed this issue with four dual-task experiments. In Exp. 1, the effect of memory load on both reaction time and temporal production was proportional to the number of items of a visuospatial pattern to hold in memory. In Exps. 2, 3, and 4, a temporal production task was combined with two visual search tasks involving either pre-attentive or attentional processing. Visual tasks interfered with temporal production: produced intervals were lengthened proportionally to the display size. In contrast, reaction times increased with display size only when a serial, effortful search was required. It appears that memory and perceptual set size, rather than nonspecific attentional or short-term memory load, can influence prospective timing.

Prevalence rate, predictors and long-term course of probable posttraumatic stress disorder after major trauma: a prospective cohort study

PubMed Central

2012-01-01

Background Among trauma patients relatively high prevalence rates of posttraumatic stress disorder (PTSD) have been found. To identify opportunities for prevention and early treatment, predictors and course of PTSD need to be investigated. Long-term follow-up studies of injury patients may help gain more insight into the course of PTSD and subgroups at risk for PTSD. The aim of our long-term prospective cohort study was to assess the prevalence rate and predictors, including pre-hospital trauma care (assistance of physician staffed Emergency Medical Services (EMS) at the scene of the accident), of probable PTSD in a sample of major trauma patients at one and two years after injury. The second aim was to assess the long-term course of probable PTSD following injury. Methods A prospective cohort study was conducted of 332 major trauma patients with an Injury Severity Score (ISS) of 16 or higher. We used data from the hospital trauma registry and self-assessment surveys that included the Impact of Event Scale (IES) to measure probable PTSD symptoms. An IES-score of 35 or higher was used as indication for the presence of probable PTSD. Results One year after injury measurements of 226 major trauma patients were obtained (response rate 68%). Of these patients 23% had an IES-score of 35 or higher, indicating probable PTSD. At two years after trauma the prevalence rate of probable PTSD was 20%. Female gender and co-morbid disease were strong predictors of probable PTSD one year following injury, whereas minor to moderate head injury and injury of the extremities (AIS less than 3) were strong predictors of this disorder at two year follow-up. Of the patients with probable PTSD at one year follow-up 79% had persistent PTSD symptoms a year later. Conclusions Up to two years after injury probable PTSD is highly prevalent in a population of patients with major trauma. The majority of patients suffered from prolonged effects of PTSD, underlining the importance of prevention, early detection, and treatment of injury-related PTSD. PMID:23270522

Three prospective randomised studies were conducted to compare pancreatoduodenectomy (PD) with duodenum-preserving pancreatic head resection (DPPHR) in patients suffering from chronic pancreatitis (cP). In these three series, the superiority of the duodenum-preserving technique with regard to quality of life (QOL) and pain relief has been demonstrated. Long-term follow-up investigations have not been published so far. The present paper reports on a 5-year follow-up study of a prospective, non-randomised trial comparing classic Whipple procedure (PD) with Beger DPPHR. Seventy patients were initially enrolled in this study. Fifty-one patients were left for the present long-term outcome analysis (PD, n = 24; DPPHR, n = 27). The follow-up included the following parameters: QOL, pain intensity, endocrine and exocrine function, and body mass index (BMI). The median follow-up was 63.5 (range 56-67) months. Two patients in the DPPHR group and none in the PD group underwent a re-operation. The QOL scores of the relevant symptom scales (nausea, pain, diarrhoea) and functional parameters (physical status, working ability, global QOL) were significantly better in the DPPHR group than in the PD group. Pain intensity as self-assessed by the patients was less pronounced in the DPPHR group (P < 0.001), whereas the frequency of acute episodes and analgesic medication did not differ between the two groups. No difference was observed between the two groups with regard to endocrine and exocrine function. The values of the median body mass index (BMI) in the PD group [23.4 (range 18.5-25.0) kg/m(2)] and in the DPPHR group [24.2 (range 17.9-27.8) kg/m(2)] were comparable. The 5-year outcome remained stable compared to the early post-operative data published elsewhere. This 5-year long-term outcome analysis documents the superiority of the Beger duodenum-preserving technique over the classic Whipple procedure in terms of QOL and pain intensity as self-assessed by the patients.

Prospective national registry data on 98 patients were studied to determine the long-term outcome of immune related lymphoproliferative disease (LPD) and define prognostic factors. Seventy-three developed LPD following organ transplant (26 liver, 21 heart, 15 kidney, nine bone marrow [BM], two bowel). Twenty-five had non-transplant related immunosuppression. Age was 1.1-17 years (median 8.6). Fifty-eight patients had lymphomatous, 21 systemic and 17 lymphadenopathic disease. Sixty (73%) were disseminated and 22 (27%) localized. Thirty-three (54%) were monoclonal. Seventy-three (83%) were Epstein-Barr virus (EBV) positive. Median follow-up was 7.6 years. LPD developed earlier after liver and BM as compared to heart or kidney transplant. Five-year overall survival (OS) was 58%. Prognosis was best after liver and kidney transplant (OS >77%). Mortality was higher following heart (2.5 times) and BM transplant (5 times). Adverse prognostic factors were disseminated or lymphomatous disease and lack of reduction of immunosuppression. With appropriate reduction of immunosuppression, rituximab and low-dose chemotherapy, long-term survival is high.

Systematic evaluation and validation of new prognostic and predictive markers, technologies and interventions for colorectal cancer (CRC) is crucial for optimizing patients' outcomes. With only 5-15% of patients participating in clinical trials, generalizability of results is poor. Moreover, current trials often lack the capacity for post-hoc subgroup analyses. For this purpose, a large observational cohort study, serving as a multiple trial and biobanking facility, was set up by the Dutch Colorectal Cancer Group (DCCG). The Prospective Dutch ColoRectal Cancer cohort is a prospective multidisciplinary nationwide observational cohort study in the Netherlands (yearly CRC incidence of 15 500). All CRC patients (stage I-IV) are eligible for inclusion, and longitudinal clinical data are registered. Patients give separate consent for the collection of blood and tumor tissue, filling out questionnaires, and broad randomization for studies according to the innovative cohort multiple randomized controlled trial design (cmRCT), serving as an alternative study design for the classic RCT. Objectives of the study include: 1) systematically collected long-term clinical data, patient-reported outcomes and biomaterials from daily CRC practice; and 2) to facilitate future basic, translational and clinical research including interventional and cost-effectiveness studies for both national and international research groups with short inclusion periods, even for studies with stringent inclusion criteria. Seven months after initiation 650 patients have been enrolled, eight centers participate, 15 centers await IRB approval and nine embedded cohort- or cmRCT-designed studies are currently recruiting patients. This cohort provides a unique multidisciplinary data, biobank, and patient-reported outcomes collection initiative, serving as an infrastructure for various kinds of research aiming to improve treatment outcomes in CRC patients. This comprehensive design may serve as an example for other tumor types.

Prospective memory (PM) impairments are common following acquired brain injury (ABI). PM is the ability to keep a goal in mind for future action and interventions have the potential to increase independence. This review aimed to evaluate studies examining PM rehabilitation approaches in adults and children with ABI. Relevant literature was identified using PsycARTICLES (1894 to present), PsycINFO (1880 to present), the Cochrane Library (1972 to present), MEDLINE PubMed, reference lists from relevant journal articles, and searches of key journals. Literature searches were conducted using variants of the terms brain injury, stroke, encephalitis, meningitis, and tumor, combined with variants of the terms rehabilitation and prospective memory. Of the 435 papers identified, 11 were included in the review. Findings demonstrated a variety of interventions to alleviate PM deficits, including compensatory strategies (e.g., external memory aids) that provide either content-specific or content-free cueing, and remediation strategies (e.g., meta-cognitive training programs) aimed at improving the self-monitoring of personal goals. Risk of bias for individual studies was considered and the strengths and limitations of each of the included studies and the review itself were discussed. Interventions used with adults can be effective; PM abilities can be improved by using simple reminder systems and performance can be generalized to facilitate everyday PM functioning. There is, however, a lack of research of PM interventions conducted with children with ABI, and pediatric interventions need to consider on-going cognitive maturation. (JINS, 2017, 22, 1-12).

OBJECTIVE To evaluate the short- to medium-term outcomes after artificial urinary sphincter (AUS) placement from a large, multi-institutional, prospective, follow-up study. We hypothesize that along with radiation, patients with any history of a direct surgery to the urethra will have higher rates of eventual AUS explantation for erosion and/or infection. MATERIALS AND METHODS A prospective outcome analysis was performed on 386 patients treated with AUS placement from April 2009 to December 2012 at 8 institutions with at least 3 months of follow-up. Charts were analyzed for preoperative risk factors and postoperative complications requiring explantation. RESULTS Approximately 50% of patients were considered high risk. High risk was defined as patients having undergone radiation therapy, urethroplasty, multiple treatments for bladder neck contracture or urethral stricture, urethral stent placement, or a history of erosion or infection in a previous AUS. A total of 31 explantations (8.03%) were performed during the follow-up period. Overall explantation rates were higher in those with prior radiation and prior UroLume. Men with prior AUS infection or erosion also had a trend for higher rates of subsequent explantation. Men receiving 3.5-cm cuffs had significantly higher explantation rates than those receiving larger cuffs. CONCLUSION This outcomes study confirms that urethral risk factors, including radiation history, prior AUS erosion, and a history of urethral stent placement, increase the risk of AUS explantation in short-term follow-up.

Objective There is extensive evidence of negative consequences of childhood maltreatment for IQ, academic achievement, and post-traumatic stress disorder (PTSD) and increased attention to neurobiological consequences. However, few prospective studies have assessed the long-term effects of abuse and neglect on executive functioning. The current study examines whether childhood abuse and neglect predicts components of executive functioning and nonverbal reasoning ability in middle adulthood and whether PTSD moderates this relationship. Method Using a prospective cohort design, a large sample (N = 792) of court-substantiated cases of childhood physical and sexual abuse and neglect (ages 0-11) and matched controls were followed into adulthood (mean age = 41). Executive functioning was assessed with the Trail Making B test and non-verbal reasoning with Matrix Reasoning. PTSD (DSM-III-R lifetime diagnosis) was assessed at age 29. Data were analyzed using ordinary least squares regressions, controlling for age, sex, and race and possible confounds of IQ, depression, and excessive alcohol use. Results In multivariate analyses, childhood maltreatment overall and childhood neglect predicted poorer executive functioning and non-verbal reasoning at age 41, whereas physical and sexual abuse did not. A past history of PTSD did not mediate or moderate these relations. Conclusions Childhood maltreatment and neglect specifically have a significant long-term impact on important aspects of adult neuropsychological functioning. These findings suggest the need for targeted efforts dedicated to interventions for neglected children. PMID:23876115

Sarcopenia is characterized by muscle mass depletion and decrease in muscle power or physical activity. We previously reported that low skeletal muscle mass (SMM) is closely involved with posttransplant mortality in patients undergoing living donor liver transplantation (LDLT). The aim of this study was to prospectively investigate the effects of pretransplant sarcopenia on survival and examine sequential changes in sarcopenic parameters after LDLT. Sarcopenia was defined by measuring SMM using a multifrequency body composition analyzer and assessing grip strength (GS) in 72 adults who underwent LDLT at Kyoto University Hospital between January 2013 and October 2015. The effects of pretransplant sarcopenia on short-term survival and sequential changes in SMM and GS were prospectively analyzed. Of 72 patients, 10 (14%) were defined as having pretransplant sarcopenia. Overall survival rates were significantly lower in patients with sarcopenia (n = 10) than those without sarcopenia (n = 62; P < 0.001). SMM worsened after LDLT and did not return to preoperative levels until 1 y after LDLT. In contrast, GS returned to preoperative levels at 6 mo after LDLT, following sharp decrease at 1 mo after LDLT. This prospective study confirmed that pretransplant sarcopenia is closely associated with short-term survival after LDLT and that GS recovers before SMM. Copyright © 2016 Elsevier Inc.

Prospective, randomized, single-center, clinical trial. To prospectively examine the 7- and 10-year outcomes of cervical arthroplasty to anterior cervical discectomy and fusion (ACDF). Degeneration of the cervical discs causing radiculopathy is a frequent source of surgical intervention, commonly treated with ACDF. Positive clinical outcomes are associated with arthrodesis techniques, yet there remains a long-term concern for adjacent segment change. Cervical disc arthroplasty has been designed to mitigate some of the challenges associated with arthrodesis whereas providing for a similar positive neurological outcome. As data has been collected from numerous prospective US FDA IDE trials, longer term outcomes regarding adjacent segment change may be examined. As part of an FDA IDE trial, a single center collected prospective outcomes data on 47 patients randomized in a 1:1 ratio to ACDF or arthroplasty. Success of both surgical interventions remained high at the 10-year interval. Both arthrodesis and arthroplasty demonstrated statistically significant improvements in neck disability index, visual analog scale neck and arm pain scores at all intervals including 7- and 10-year periods. Arthroplasty demonstrated an advantage in comparison to arthrodesis as measured by final 10-year NDI score (8 vs. 16, P = 0.0485). Patients requiring reoperation were higher in number in the arthrodesis cohort (32%) in comparison with arthroplasty (9%) (P = 0.055). At 7 and 10 years, cervical arthroplasty compares favorably with ACDF as defined by standard outcomes scores in a highly selected population with radiculopathy. 1.

To conduct a prospective cohort study to clarify the relationship between human leukocyte antigen (HLA) polymorphisms and the seroconversion of hepatitis B e antigen (HBeAg). In the prospective cohort study, 81 HBeAg-positive children with chronic hepatitis B virus (HBV) infection from 40 unrelated families were recruited and followed-up regularly for a mean period of 17.70 +/- 3.23 years. The association between HLA antigen and the age at HBeAg seroconversion was analyzed using Cox regression model with shared frailties under left truncation and right censorship. HLA-B61 and HLA-DQB1*0503 antigens predicted a higher HBeAg seroconversion rate (relative incidence = 6.17 and 3.22, P = .024 and .017, respectively). Within-family frailty in our sibling cohort study demonstrated a negligible or a low degree of within-family correlation with spontaneous HBeAg seroconversion in each HLA antigen. HLA class I antigen B61 and class II antigen DQB1*0503 are associated with earlier HBeAg seroconversion in Taiwanese children with chronic HBV infection.

The high cost and undesirable consequences of polypharmacy are well-recognized problems among elderly long-term care (LTC) residents. Despite the implementation of the 1987 Omnibus Budget Reconciliation Act, which requires pharmacist review of drug regimens in this setting, medical and drug costs for LTC residents have continued to increase. This study evaluates the North Carolina Long-Term Care Polypharmacy Initiative, a large-scale medication therapy management program (MTMP) that combined drug utilization review activities with drug regimen review techniques. This was a prospective records-based study that used a difference-in-difference model with both historical and nonintervention group controls. To ensure equivalence among subjects, propensity scoring was used to match study subjects from participating LTC facilities with comparison subjects from nonparticipating facilities. Residents with interventions were grouped for analysis by intervention type-retrospective only, prospective only, or dual type (residents with both prospective and retrospective interventions)-and by intervention stage-review, recommendation, and drug change-plus an all-inclusive "all types" grouping that aggregated groups by intervention type, for a total of 10 total cohorts. In the overall population of 5255 study subjects identified, a US $21.63 per member per month drug-cost savings was observed. Although only 1 of 10 cohorts had a change in the number of drug fills, substantial reductions in 2 of 5 types of drug alerts were observed in all 10 cohorts. A reduction in the relative risk for hospitalization (0.84 [95% CI, 0.71-1.00]) was observed in the cohort of residents receiving a retrospective review. This Initiative suggests that an MTMP can be quickly launched in a large number of LTC facility residents to produce monetary drug-cost savings and improved health outcomes. Additionally, the evaluation of this program illustrates the utility of using propensity scoring techniques to target future intervention groups in a cost-effective manner.

Medical error is common in crises, and the majority of observed errors are nontechnical in nature. The long-term impact of teaching crisis nontechnical skills to residents has not been evaluated. The objective of this study was to determine the effect of simulation-based teaching of crisis nontechnical skills compared to controls one year after initial teaching. This was a prospective study using both historical controls and a before-and-after methodology to evaluate the effect of a high-fidelity simulation curriculum that used crisis resource management principles to teach nontechnical skills. Postgraduate year 2 and 3 residents were invited to take part in a prospective training course over 2 years. The primary outcome was leader performance evaluated by expert raters using the previously validated 7-point Ottawa Global Rating Scale. Overall, 23 residents performed 30 simulations over the 2 years with the intervention group of 7 residents being assessed in both years. After adjustment, the postgraduate year 3 intervention group who received training the previous year had significantly higher overall performance scores than all postgraduate year 2 scores (1.09 95% confidence interval 0.70-1.47, P < .001) and the historical postgraduate year 3 cohort who received no prior training (1.20, 95% confidence interval 0.37-2.03, P = .005). There was no decay of skills noted over the course of the study. Postgraduate year 3 residents who had prior training had significantly improved crisis performance compared to historical postgraduate year 3 controls and untrained postgraduate year 2 residents. There were no significant differences between the crisis performance of postgraduate year 2 residents and the untrained postgraduate year 3 controls. This confirms the beneficial effect and long-term retention after crisis nontechnical skill training. Copyright © 2016 Elsevier Inc. All rights reserved.

There is a lack of studies investigating social capital at the workplace level in small and relatively homogeneous work-units. The aim of the study was to investigate whether work-unit social capital predicts a lower risk of individual long-term sickness absence among Danish hospital employees followed prospectively for 1 year. This study is based on the Well-being in HospitAL Employees cohort. The study sample consisted of 32 053 individuals nested within 2182 work-units in the Capital Region of Denmark. Work-unit social capital was measured with an eight-item scale covering elements of trust, justice and collaboration between employees and leaders. Social capital at the work-unit level was computed as the aggregated mean of individual-level social capital within each work-unit. Data on long-term sickness absence were retrieved from the employers' payroll system and were operationalised as ≥29 consecutive days of sickness absence. We used a 12-point difference in social capital as the metric in our analyses and conducted two-level hierarchical logistic regression analysis. Adjustments were made for sex, age, seniority, occupational group and part-time work at the individual level, and work-unit size, the proportion of female employees and the proportion of part-time work at the work-unit level. The OR for long-term sickness absence associated with a 12-point higher work-unit social capital was 0.73 (95% CI 0.68 to 0.78). Further, we found an association between higher work-unit social capital and lower long-term sickness absence across quartiles of social capital: compared with the lowest quartile, the OR for long-term sickness absence in the highest quartile was 0.51 (95% CI 0.44 to 0.60). Our study provides support for work-unit social capital being a protective factor for individual long-term sickness absence among hospital employees in the Capital Region of Denmark. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Background Customization of the tracheoesophageal (TE) voice prosthesis (VP) is often preferred over surgical closure to prevent aspiration around the VP in laryngectomized patients with an enlarged tracheoesophageal puncture (TEP), but has not been thoroughly evaluated. Study Design Single-institution prospective trial. Methods A prospective trial was conducted to evaluate the effectiveness of a customized VP with the addition of an enlarged tracheal and/or esophageal collar in patients with leakage around an enlarged TEP. Absence of leakage around the VP after placement defined immediate effectiveness. Long-term success was defined by the prevention of adverse events related to leakage during the study period. Events that defined failure included: permanent gastrostomy dependence, aspiration pneumonia, and/or surgical TEP closure. Results Twenty-one patients with enlarged TEP were enrolled (2003-2006). Insertion of a customized VP was unsuccessful in 1 patient; 145 customizations were performed in the remaining 20 patients (median: 3.5 customizations) during the trial period. Seventy-seven percent (112/145) of customizations prevented leakage immediately after VP insertion. The most common adverse event was dislodgement of the prosthesis (11%) or the collar alone (7%) in 18% (26/145) of customized VP placements. Six patients who died of disease were not evaluable for long-term outcomes. Long-term success was achieved in 80% (12/ 15) of evaluable patients who avoided permanent gastrostomy, aspiration pneumonia, and surgical TEP closure. Conclusions Prosthetic customization offers an effective method to prevent leakage around the VP in many patients with an enlarged TEP, thereby preserving TE voice while avoiding surgical closure in this high risk population.

A large body of literature suggests a clear, concurrent association between peer approval and self-esteem in adolescence. However, little empirical work exists on either the prospective or reciprocal relation between peer approval and self-esteem during this age period. Moreover, it is unclear from past research whether both subjectively perceived peer approval and objectively measured peer approval are related to subsequent self-esteem over time (and vice versa) and whether these paths have long-term associations into adulthood. Using data from a large longitudinal study that covers a time span of 2 decades, we examined reciprocal, prospective relations between self-esteem and peer approval during ages 12-16 in addition to long-term relations between these variables and later social constructs at age 35. Cross-lagged regression analyses revealed small but persistent effect sizes from both types of peer approval to subsequent self-esteem in adolescence, controlling for prior self-esteem. However, effects in the reverse direction were not confirmed. These findings support the notion that peer relationships serve an important function for later self-esteem, consistent with many theoretical tenets of the importance of peers for building a strong identity. Finally, we found long-term relations between adult social constructs and adolescent objective and subjective peer approval as well as self-esteem. Therefore, not only do peer relationships play a role in self-esteem development across adolescence, but they remain impactful throughout adulthood. In sum, the current findings highlight the lasting, yet small link between peer relationships and self-esteem development and call for investigations of further influential factors for self-esteem over time.

Background Identifying potentially modifiable risk factors for medication non-adherence in older adults is important in order to enhance screening and intervention efforts designed to improve medication-taking behavior and health outcomes. The current study sought to determine the unique contribution of prospective memory (i.e., “remembering to remember”) to successful self-reported medication management in older adults. Methods Sixty-five older adults with current medication prescriptions completed a comprehensive research evaluation of sociodemographic, psychiatric, and neurocognitive functioning, which included the Memory for Adherence to Medication Scale (MAMS), Prospective and Retrospective Memory Questionnaire (PRMQ), and a performance-based measure of prospective memory that measured both semantically-related and semantically-unrelated cue-intention (i.e., when-what) pairings. Results A series of hierarchical regressions controlling for biopsychosocial, other neurocognitive, and medication-related factors showed that elevated complaints on the PM scale of the PRMQ and worse performance on an objective semantically-unrelated event-based prospective memory task were independent predictors of poorer medication adherence as measured by the MAMS. Conclusions Prospective memory plays an important role in self-report of successful medication management among older adults. Findings may have implications for screening for older individuals “at risk” of non-adherence, as well as the development of prospective memory-based interventions to improve medication adherence and, ultimately, long-term health outcomes in older adults.

In the last few years, reflective thinking becomes very popular term in the world of education, especially in professional education of teachers. One of goals of the educational personnel and teacher institutions create responsible prospective teachers and they are able reflective thinking. Reflective thinking is a future competence that should be taught to students to face the challenges and to respond of demands of the 21st century. Reflective thinking can be applied in mathematics becauseby reflective thinking, students can improve theircuriosity to solve mathematical problem. In solving mathematical problem is assumed that cognitive style has an impact on prospective teacher's mental activity. As a consequence, reflective thinking and cognitive style are important things in solving mathematical problem. The subject, in this research paper, isa female-prospective teacher who has fielddependent cognitive style. The purpose of this research paperis to investigate the ability of prospective teachers' reflective thinking in solving mathematical problem. This research paper is a descriptive by using qualitativeapproach. To analyze the data related to prospectiveteacher's reflective thinking in solving contextual mathematicalproblem, the researchers focus in four main categories which describe prospective teacher's activities in using reflective thinking, namely; (a) formulation and synthesis of experience, (b) orderliness of experience, (c) evaluating the experience and (d) testing the selected solution based on the experience.

Nasopharyngeal carcinoma (NPC) is very rare in childhood. It differs from its adult counterpart in the prevalence of the nonkeratinizing, undifferentiated subtype and by an advanced clinical stage at onset and better chances of survival. The risk of long-term treatment-related toxicity also may be a more important issue in younger individuals. A prospective chemoradiotherapy protocol for pediatric NPC was started in Italy in 2000 within the framework of the Rare Tumors in Pediatric Age (TREP) project. Three courses of cisplatin/5-fluorouracil induction chemotherapy were followed by radiotherapy (doses up to 65 grays) with concomitant cisplatin. Forty-six patients (ages 9-17 years) were considered eligible for the study over a 10-year period. The ratio of observed to expected cases based on epidemiological data was approximately 1 for both children and adolescents. All but 1 patient had lymph node involvement, and 5 patients had distant metastases. The rate of response to primary chemotherapy was 90%. The 5-year overall and progression-free survival rates were 80.9% and 79.3%, respectively (median follow-up, 62 months). The only statistically significant prognostic variable was the presence or absence of distant metastases. A 65% incidence of late sequelae was reported. This study demonstrates the feasibility and efficacy of a prospective protocol even for such rare tumors as pediatric NPC. The use of lower radiotherapy doses than those used in adults did not affect locoregional failure rates. Long-term follow-up will be needed to obtain more information on both survival and treatment sequelae. The next objective will be to establish broader, international prospective cooperation schemes.

Most studies rely on cross-sectional retrospective reports from adult samples to collect information about adverse childhood experiences (ACEs) to examine relationships with adult outcomes. The problems associated with these reports have long been debated, with only a few studies determining their reliability and validity and fewer still reaching consensus on the matter. This paper uses repeat prospective and retrospective reports of adverse childhood experiences from two respondent sources in the South African Birth to Twenty Plus (Bt20+) cohort to explore agreement and concordance in the prospective reporting of ACEs by caregivers and respective children as adolescents and then as young adults. The findings demonstrate little overall agreement between prospective and retrospective accounts of childhood experiences, with 80% of kappa values below the moderate agreement cutoff (k = .41). The highest levels of agreement were found between prospective and retrospective reporting on parental and household death (kappas ranging from .519 to .944). Comparisons between prospective caregiver reports and retrospective young adult reports yielded high concordance rates on sexual and physical abuse and exposure to intimate partner violence (91.0%, 87.7% and 80.2%, respectively). The prevalence of reported ACEs varied with the age of the respondent, with adolescents reporting much higher rates of exposure to violence, physical and sexual abuse than are reported retrospectively or by caregivers. This variation may partly reflect actual changes in circumstances with maturation, but may be influenced by developmental stage and issues of memory, cognition and emotional state more than has been considered in previous analyses. More research, across disciplines, is needed to understand these processes and their effect on recall. Long-term prospective studies are critical for this purpose. In conclusion, methodological research that uses a range of information sources to establish the reliability and validity of both retrospective and prospective reports ‒ recognizing that the two approaches may fundamentally answer different questions ‒ should be encouraged.

To investigate the changes in rehabilitants' perceived work ability after rehabilitation for chronic musculoskeletal disorders with respect to the baseline characteristics. Prospective cohort study based on register and repeated survey data. Public sector employees in ten towns and five hospital districts. A total of 854 employees who participated in the rehabilitation programme owing to common chronic musculoskeletal disorders between 1997 and 2009. Interdisciplinary, biopsychosocial, inpatient rehabilitation programme targeting people of working age with common chronic musculoskeletal disorders. The programme was executed in different rehabilitation centres across the country and funded by the Social Insurance Institution of Finland. Differences in perceived work ability level before and after rehabilitation. Data were derived from repeated surveys on average 2.1 years before rehabilitation, and 1.5 years (short-term follow-up) and 6.0 years (long-term follow-up) after rehabilitation. Before the rehabilitation, perceived work ability was 7.13 (SD 1.84) among the rehabilitants and 7.27 (SD 1.72) in the matched reference population. Among rehabilitants, this figure decreased by 0.82 (95% confidence interval -0.98 to -0.67) in the short-term and by 1.26 (95% confidence interval -1.45 to -1.07) in the long-term follow-up. Only slight differences in steepness of this deterioration were observed between subgroups, created based on the participants' baseline characteristics. Perceived work ability of participants, in an interdisciplinary biopsychosocial rehabilitation programme for common musculoskeletal disorders, deteriorated regardless of any studied pretreatment characteristics. The improvement of work ability may be an unrealistic goal for participants in this type of rehabilitation. © The Author(s) 2014.

To compare the efficacy of a personal dietary intervention on gestational weight gain control with a general intervention promoting healthy eating. Prospective, controlled study including 154 low-risk pregnant women randomly allocated to two groups: 77 receiving a personalized diet plan and a close follow-up by a dietician (intervention group), 77 receiving standard dietary care by means of a brochure on healthy eating during pregnancy (control group). Pre-pregnancy weight, gestational age, height, weight and BMI at baseline, weight at term, gestational age at delivery and newborn weight were recorded for all participants. The primary end-point was the difference in body weight between baseline and term. Secondary end-points were the difference in body weight between pre-pregnancy and term and in newborn weights. Maternal weight gain at term was significantly lower both as compared to pre-pregnancy weight (8.2 ± 4.0 vs. 13.4 ± 4.2 kg; p < 0.001) and to weight at baseline (7.7 ± 3.8 vs. 13.7 ± 4.3 kg; p < 0.001) in the intervention group as compared to controls. A positive, significant correlation between the delta weight between baseline and term and newborn weight was observed in both groups, but stronger in patients from the intervention group (intervention group R = 0.76, p < 0.001; control group R = 0.35, p = 0.01). This study suggests that a personalized nutritional intervention, in which the dietician plays an active role within the obstetric team, may represent a successful approach in limiting weight gain in pregnant women.

Results from some retrospective studies suggest a possible increased risk of glioma and acoustic neuroma in users of mobile phones. The relation between mobile phone use and incidence of intracranial central nervous system (CNS) tumours and other cancers was examined in 791,710 middle-aged women in a UK prospective cohort, the Million Women Study. Cox regression models were used to estimate adjusted relative risks (RRs) and 95% confidence intervals (CIs). Women reported mobile phone use in 1999 to 2005 and again in 2009. During 7 years' follow-up, 51,680 incident invasive cancers and 1,261 incident intracranial CNS tumours occurred. Risk among ever vs never users of mobile phones was not increased for all intracranial CNS tumours (RR = 1.01, 95% CI = 0.90-1.14, P = 0.82), for specified CNS tumour types nor for cancer at 18 other specified sites. For long-term users compared with never users, there was no appreciable association for glioma (10+ years: RR = 0.78, 95% CI = 0.55-1.10, P = 0.16) or meningioma (10+ years: RR = 1.10, 95% CI = 0.66-1.84, P = 0.71). For acoustic neuroma, there was an increase in risk with long term use vs never use (10+ years: RR = 2.46, 95% CI = 1.07-5.64, P = 0.03), the risk increasing with duration of use (trend among users, P = 0.03).

To evaluate the sexual function and quality of life pre- and post-gynecological cancer treatment with high-dose rate brachytherapy in the short term. This is a descriptive and prospective study involving 20 women diagnosed with gynecological cancer aged between 18 and 70 years, resident in Florianopolis and the surrounding region. We used the Quality of Life Questionnaire Core-30 (QLQ-C30) 3.0 to assess quality of life pre- and post-brachytherapy treatment and the Female Sexual Function Index (FSFI) to assess sexual function. Regarding quality of life, significant worsening was observed for the items loss of appetite (p = 0.002) and diarrhea (p = 0.045) from pre- to post-brachytherapy treatment, whereas constipation (p = 0.013) improved. For sexual function, the statistical difference was found exclusively in the domain of lubrication reduction (p = 0.046). Only nine women were sexually active before and after brachytherapy treatment. There was a worsening of quality of life in comparing pre- and post-evaluations related to gastrointestinal symptoms over a period equivalent to 40 days. Regarding sexual function, lack of lubrication was identified in short-term post-gynecological cancer brachytherapy.

Background The short-term quality of life (QoL) in cervical dystonia (CD) after treating with abobotulinum toxin A (Abo-BTX A) and neubotulinum toxin A (Neu-BTX A) have been studied in Thai CD patients. However; the long-term study has not been published. Objective The aim of the present study was to determine long-term improvement of the health-related quality of life (HRQoL) after eight injections of Abo-BTX A over 2 years in CD patients. Patients and methods A 2-year prospective study on the QoL of CD patients, as measured by HRQoL, before and after receiving eight injections of Abo-BTX A at 3-month intervals over a 2-year treatment period was performed. The disease-specific HRQoL was assessed before and after the treatment by using the Cervical Dystonia Impact Profile-58 (CDIP-58) questionnaire. The general HRQoL was assessed by using the Medical Outcomes 36-Item Short Form Health Survey (SF-36), while depressive disorder screening was assessed by using the Center of Epidemiologic Studies-Depression (CES-D) questionnaire. The SF-36 and CES-D questionnaire were administered before treatment and every 3 months before the next injection for a 2-year period. Results A total of 20 CD patients were enrolled from January 2013 to December 2015. CDIP-58 showed a significant improvement after long-term injections of Abo-BTX A in all domains (P < 0.001). However, only vitality domain of SF-36, which assessed general HRQoL, showed a significant improvement after long-term injections (P = 0.037). There was no prevalence of depressive disorder in all patients (CES-D score <20) in this study. Conclusion The Abo-BTX A injections at 3-month intervals over a 2-year period improved the CDIP-58 scores, which assess disease-specific HRQoL, as well as an increased vitality domain of general HRQoL. No patient suffered from depression in this study. PMID:29731634

The purpose of the present systematic review was to evaluate the soft tissue/hard tissue ratio in bilateral sagittal split advancement osteotomy (BSSO) with rigid internal fixation (RIF) or wire fixation (WF). The databases PubMed, Medline, CINAHL, Web of Science, Cochrane Library, and Google Scholar Beta were searched. From the original 711 articles identified, 12 were finally included. Only 3 studies were prospective and 9 were retrospective. The postoperative follow-up ranged from 3 months to 12.7 years for RIF and 6 months to 5 years for WF. The short- and long-term ratios for the lower lip to lower incisor for BSSO with RIF or WF were 50%. No difference between the short- and long-term ratios for the mentolabial-fold to point B and soft tissue pogonion to pogonion could be observed. It was a 1:1 ratio. One exception was seen for the long-term results of the soft tissue pogonion to pogonion in BSSO with RIF; they tended to be greater than a 1:1 ratio. The upper lip mainly showed retrusion but with high variability. Despite a large number of studies on the short- and long-term effects of mandibular advancement by BSSO, the results of the present systematic review have shown that evidence-based conclusions on soft tissue changes are still unknown. This is mostly because of the inherent problems of retrospective studies, inferior study designs, and the lack of standardized outcome measures. Well-designed prospective studies with sufficient sample sizes that have excluded patients undergoing additional surgery (ie, genioplasty or maxillary surgery) are needed. 2010 American Association of Oral and Maxillofacial Surgeons.

The efficacy of transoral incisionless fundoplication (TIF) performed with the EsophyX device (Redmond, Washington, USA) and its long-term outcomes in gastresophageal reflux disease (GERD) are debated. We, therefore, performed a systematic review with meta-analysis of studies evaluating the role of TIF in GERD. A systematic search of EMBASE, SCOPUS, PubMed, and the Cochrane Library Central was performed. All original studies reporting outcomes in GERD patients who underwent TIF were identified. Only randomized controlled trials (RCTs) evaluating the efficacy of TIF, and prospective observational studies reporting outcomes after TIF were included. A total of 18 studies (963 patients) published between 2007 and 2015 were identified, including five RCTs and 13 prospective observational studies. The pooled relative risk of response rate to TIF versus PPIs/sham was 2.44 (95 % CI 1.25-4.79, p = 0.0009) in RCTs in the intention-to-treat analysis. The total number of refluxes was reduced after TIF compared with the PPIs/sham group. The esophageal acid exposure time and acid reflux episodes after TIF were not significantly improved. Proton-pump inhibitors (PPIs) usage increased with time and most of the patients resumed PPIs treatment at reduced dosage during the long-term follow-up. The total satisfaction rate after TIF was about 69.15 % in 6 months. The incidence of severe adverse events consisting of gastrointestinal perforation and bleeding was 2.4 %. TIF is an alternative intervention in controlling GERD-related symptoms with comparable short-term patient satisfaction. Long-term results showed decreased efficacy with time. Patients often resume PPIs at reduced doses in the near future.

Long-term aircraft noise exposure may increase the risk of cardiovascular disease, but no study has investigated chronic effects on the metabolic system. The aim of this study was to investigate effects of long-term aircraft noise exposure on body mass index (BMI), waist circumference, and type 2 diabetes. Furthermore, we explored the modifying effects of sleep disturbance. This prospective cohort study of residents of Stockholm County, Sweden, followed 5,156 participants with normal baseline oral glucose tolerance tests (OGTT) for up to 10 years. Exposure to aircraft noise was estimated based on residential history. Information on outcomes and confounders was obtained from baseline and follow-up surveys and examinations, and participants who developed prediabetes or type 2 diabetes were identified by self-reported physician diagnosis or OGTT at follow-up. Adjusted associations were assessed by linear, logistic, and random-effects models. The mean (± SD) increases in BMI and waist circumference during follow-up were 1.09 ± 1.97 kg/m2 and 4.39 ± 6.39 cm, respectively. The cumulative incidence of prediabetes and type 2 diabetes was 8% and 3%, respectively. Based on an ordinal noise variable, a 5-dB(A) increase in aircraft noise was associated with a greater increase in waist circumference of 1.51 cm (95% CI: 1.13, 1.89), fully adjusted. This association appeared particularly strong among those who did not change their home address during the study period, which may be a result of lower exposure misclassification. However, no clear associations were found for BMI or type 2 diabetes. Furthermore, sleep disturbances did not appear to modify the associations with aircraft noise. Long-term aircraft noise exposure may be linked to metabolic outcomes, in particular increased waist circumference.

Mediational Pathways Through Which Positive and Negative Emotionality Contribute to Anhedonic Symptoms of Depression: A Prospective Study of Adolescents

PubMed Central

Hankin, Benjamin L.

2009-01-01

This study takes a developmental psychopathological approach to examine mechanisms through which baseline levels of positive emotionality (PE) and negative emotionality (NE) prospectively predict increases in anhedonic depressive symptoms in a community sample of 350 adolescents (6th–10th graders). Dependent stressors mediated the relationship between baseline levels of NE and anhedonic depressive symptoms after controlling for initial symptoms. Supportive relationships mediated the relationship between baseline levels of PE and anhedonic depressive symptoms, after controlling for baseline symptoms. In addition, NE × PE interacted to predict later anhedonic depressive symptoms, such that adolescents with low levels of PE and high levels of NE experienced the greatest increase in anhedonic depressive symptoms. Last, supportive relationships interacted with baseline PE to predict prospective changes in anhedonic depressive symptoms, such that adolescents with low PE and low supportive relationships experienced the greatest increase in anhedonic depressive symptoms. Results are discussed in terms of current theoretical models of the link between temperament and depression. PMID:19184402

Most surgeons administer prophylactic antibiotics for 3 to 5 days postoperatively. However, the Center for Disease Control (CDC) guideline recommends antibiotic therapy for 24 hours or less in clean/uncontaminated surgery. Thus, we prospectively studied the use of short term prophylactic antibiotic therapy after gastric cancer surgery. A total of 103 patients who underwent gastric cancer surgery between October 2007 and June 2008 were prospectively enrolled in a short term prophylactic antibiotics program. One gram of cefoxitin was administered 30 minutes before the incision, and one additional gram was administered intraoperatively for cases with an operation time over 3 hours. Postoperatively, one gram was administered 3 times, every 8 hours. Patients were checked routinely for fever. All cases received open surgery, and the surgical wounds were dressed and checked for Surgical Site Infection (SSI) daily. Of the 103 patients, 15 were dropped based on exclusion criteria (severe organ dysfunction, combined resection of the colon, etc). The remaining 88 patients were included in the short-term program of prophylactic antibiotic use. Of these patients, SSIs were detected in 8 (9.1%) and fever after 2 postoperative days was detected in 11 (12.5%). The incidence of SSIs increased with patient age, and postoperative fever correlated with operation time. Short term prophylactic antibiotic usage is feasible in patients who undergo gastric cancer surgery, and where there are no grave comorbidities or combined resection.

Background To promote effective genome-scale research, genomic and clinical data for large population samples must be collected, stored, and shared. Methods We conducted focus groups with 45 members of a Seattle-based integrated healthcare delivery system to learn about their views and expectations for informed consent in genome-scale studies. Results Participants viewed information about study purpose, aims, and how and by whom study data could be used to be at least as important as information about risks and possible harms. They generally supported a tiered consent approach for specific issues, including research purpose, data sharing, and access to individual research results. Participants expressed a continuum of opinions with respect to the acceptability of broad consent, ranging from completely acceptable to completely unacceptable. Older participants were more likely to view the consent process in relational – rather than contractual – terms, compared with younger participants. The majority of participants endorsed seeking study subjects’ permission regarding material changes in study purpose and data sharing. Conclusions Although this study sample was limited in terms of racial and socioeconomic diversity, our results suggest a strong positive interest in genomic research on the part of at least some prospective participants and indicate a need for increased public engagement, as well as strategies for ongoing communication with study participants.

2016-01-01

Different treatment protocols in terms of number, diameter, and suprastructure design have been proposed for immediately loaded implants that are used to support mandibular overdentures opposed by maxillary conventional dentures. The aim of this study was to investigate the influence of these protocols on survival rates as well as clinical and prosthodontic outcomes. Several electronic databases were searched for all relevant articles published from 1966 to June 2014. Only randomized controlled trials and prospective studies with a minimum follow-up of 12 months were selected. The primary outcomes of interest were the success and survival rates of the implants. Prosthodontic complications were also evaluated. Fourteen studies fulfilled the inclusion criteria. Of the studies identified, nine were randomized controlled trials and five were prospective studies. The mean follow-up period was 3 years or less for the vast majority of the studies. The reported survival and success rates were comparable to that of conventional loading for most of the included studies. No specific immediate loading protocol seemed to perform better in terms of clinical and prosthodontic outcomes. Immediate loading protocols of mandibular overdentures seem to be a viable alternative to conventional loading. It was not possible to recommend a specific treatment protocol related to the number, diameter of the implants, and attachment system used. Long-term, well-designed studies comparing different immediate loading modalities could help to establish a protocol that delivers the most clinically predictable, efficient, and cost-effective outcome for edentulous patients in need of implant overdentures.

Despite the widespread use of retrospectively reported time to pregnancy to evaluate fertility either as an outcome or as a risk factor for chronic disease, only two small studies have directly compared prospective data with later recall. The North Carolina Early Pregnancy Study (1982-1986) collected prospective time-to-pregnancy data from the beginning of participants' pregnancy attempt. In 2010, (24-28 years later) women were sent a questionnaire including lifetime reproductive history that asked about all prior times to pregnancy. Of the 202 women with prospective time-to-pregnancy data, 76% provided recalled time to pregnancy. A lower proportion of women with times to pregnancy ≥3 cycles provided a recalled time to pregnancy than women with times to pregnancy <3 cycles. Also, high gravidity or parity was associated with a lower likelihood of providing a recalled time to pregnancy. Women with very short or very long times to pregnancy (1 cycle or ≥13 cycles) had good recall of time to pregnancy. Positive predictive values of 1 or ≥13 cycles were 73% and 68%, respectively, while positive predictive values for other categories of time to pregnancy ranged from 38% to 58%. The weighted kappa statistic for recalled versus prospective time to pregnancy was 0.72 (95% confidence interval: 0.65, 0.79). Recalled time to pregnancy showed good agreement with prospective time to pregnancy. Informative missingness must be considered when imputing recalled time to pregnancy. Associations observed in future studies can be corrected for misclassification.

To prospectively validate the SYNTAX Score II and forecast the outcomes of the randomized Evaluation of the Xience Everolimus-Eluting Stent Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) Trial. Evaluation of the Xience Everolimus Eluting Stent vs. Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization is a prospective, randomized multicenter trial designed to establish the efficacy and safety of percutaneous coronary intervention (PCI) with the everolimus-eluting stent compared with coronary artery bypass graft (CABG) surgery in subjects with unprotected left-main coronary artery (ULMCA) disease and low-intermediate anatomical SYNTAX scores (<33). After completion of patient recruitment in EXCEL, the SYNTAX Score II was prospectively applied to predict 4-year mortality in the CABG and PCI arms. The 95% prediction intervals (PIs) for mortality were computed using simulation with bootstrap resampling (10 000 times). For the entire study cohort, the 4-year predicted mortalities were 8.5 and 10.5% in the PCI and CABG arms, respectively [odds ratios (OR) 0.79; 95% PI 0.43-1.50). In subjects with low (≤22) anatomical SYNTAX scores, the predicted OR was 0.69 (95% PI 0.34-1.45); in intermediate anatomical SYNTAX scores (23-32), the predicted OR was 0.93 (95% PI 0.53-1.62). Based on 4-year mortality predictions in EXCEL, clinical characteristics shifted long-term mortality predictions either in favour of PCI (older age, male gender and COPD) or CABG (younger age, lower creatinine clearance, female gender, reduced left ventricular ejection fraction). The SYNTAX Score II indicates at least an equipoise for long-term mortality between CABG and PCI in subjects with ULMCA disease up to an intermediate anatomical complexity. Both anatomical and clinical characteristics had a clear impact on long-term mortality predictions and decision making between CABG and PCI. Published on behalf of the European Society of Cardiology.

Prospective testing of Coulomb short-term earthquake forecasts

2009-12-01

Earthquake induced Coulomb stresses, whether static or dynamic, suddenly change the probability of future earthquakes. Models to estimate stress and the resulting seismicity changes could help to illuminate earthquake physics and guide appropriate precautionary response. But do these models have improved forecasting power compared to empirical statistical models? The best answer lies in prospective testing in which a fully specified model, with no subsequent parameter adjustments, is evaluated against future earthquakes. The Center of Study of Earthquake Predictability (CSEP) facilitates such prospective testing of earthquake forecasts, including several short term forecasts. Formulating Coulomb stress models for formal testing involves several practical problems, mostly shared with other short-term models. First, earthquake probabilities must be calculated after each “perpetrator” earthquake but before the triggered earthquakes, or “victims”. The time interval between a perpetrator and its victims may be very short, as characterized by the Omori law for aftershocks. CSEP evaluates short term models daily, and allows daily updates of the models. However, lots can happen in a day. An alternative is to test and update models on the occurrence of each earthquake over a certain magnitude. To make such updates rapidly enough and to qualify as prospective, earthquake focal mechanisms, slip distributions, stress patterns, and earthquake probabilities would have to be made by computer without human intervention. This scheme would be more appropriate for evaluating scientific ideas, but it may be less useful for practical applications than daily updates. Second, triggered earthquakes are imperfectly recorded following larger events because their seismic waves are buried in the coda of the earlier event. To solve this problem, testing methods need to allow for “censoring” of early aftershock data, and a quantitative model for detection threshold as a function of distance, time, and magnitude is needed. Third, earthquake catalogs contain errors in location and magnitude that may be corrected in later editions. One solution is to test models in “pseudo-prospective” mode (after catalog revision but without model adjustment). Again, appropriate for science but not for response. Hopefully, demonstrations of modeling success will stimulate improvements in earthquake detection.

Pump-assisted versus gravity-controlled enteral nutrition in long-term percutaneous endoscopic gastrostomy patients: a prospective controlled trial.

Vomiting, aspiration, flatulence, and diarrhea are well-known negative side effects of enteral nutrition through percutaneous endoscopic gastrostomy (PEG). However, it is not yet clarified if pump-assisted (PA) or gravity-controlled (GC) application is the more comfortable and safe choice for long-term nutrition through PEG. This was a prospective, randomized, crossover study. Fifty long-term PEG patients were fed by PA nutrition (G1) and 50 patients were fed by GC nutrition (G2). Six weeks of observation (O1) was followed by a switch of method of nutritional application in both groups and an additional 6 weeks of observation (O2). Daily determination of comfort and safety was done with a standardized questionnaire. Evaluation of blood glucose levels on days 1, 21, and 42 during O1 and O2. The patients in both groups had the same medical conditions and were of the same age and sex. Far less flatulence (p < .0006) and epigastric fullness (p < .0003) was discovered in G1 during O1. Also, significantly less regurgitation (p < .0002) and vomiting of feeding diet (p < .0001) in G1 versus G2 could be observed. The rate of diarrhea (p < .0003) in G2 was higher than in G1. The daily profile of blood glucose was significantly better (p < .0008) in G1 than in G2. After the nutritional application was changed in O2, the PA group (G2) again showed a significantly better rate of flatulence, epigastric fullness, regurgitation, vomiting, diarrhea, and daily profile of blood glucose. Ninety-six percent of the patients in G2 preferred further nutrition by PA after finishing this study. All patients in G1 continued their accustomed nutrition by PA. Nutrition through PA showed not only a higher comfort rate but also increased safety, which was expressed through a low rate of regurgitation and vomiting. PA presented better glucose metabolization manifested in improved blood glucose levels. As a result of this prospective study, PA is preferable to GC and preferred by patients with long-term PEG nutrition.

Background As electronic health records and computerized workflows expand, there are unprecedented opportunities to digitally connect with patients using secure portals. To realize the value of patient portals, initial reach across populations will need to be demonstrated, as well as sustained usage over time. Objective The study aim was to identify patient factors associated with short-term and long-term portal usage after patients registered to access all portal functions. Methods We prospectively followed a cohort of patients at a large Department of Veterans Affairs (VA) health care facility who recently completed identity proofing to use the VA patient portal. Information collected at baseline encompassed patient factors potentially associated with portal usage, including: demographics, Internet access and use, health literacy, patient activation, and self-reported health conditions. The primary outcome was the frequency of portal log-ins during 6-month and 18-month time intervals after study enrollment. Results A total of 270 study participants were followed prospectively. Almost all participants (260/268, 97.0%) reported going online, typically at home (248/268, 92.5%). At 6 months, 84.1% (227/270) of participants had visited the portal, with some variation in usage across demographic and health-related subgroups. There were no significant differences in portal log-ins by age, gender, education, marital status, race/ethnicity, distance to a VA facility, or patient activation measure. Significantly higher portal usage was seen among participants using high-speed broadband at home, greater self-reported ability using the Internet, and routinely going online. By 18 months, 91% participants had logged in to the portal, and no significant associations were found between usage and demographics, health status, or patient activation. When examining portal activity between 6 and 18 months, patients who were infrequent or high portal users remained in those categories, respectively. Conclusions Short-term and long-term portal usage was associated with having broadband at home, high self-rated ability when using the Internet, and overall online behavior. Digital inclusion, or ready access to the Internet and digital skills, appears to be a social determinant in patient exposure to portal services. PMID:29042345

Advances in perinatal care have markedly increased the prospects of survival for infants born extremely preterm (EP). The aim of this study was to investigate hospitalisation rates and respiratory morbidity from five to 11 years of age in a prospective national cohort of EP children born in the surfactant era. This was a national prospective cohort study of all children born in Norway during 1999 and 2000 with gestational age (GA) < 28 weeks or birth weight < 1000 grams, and of individually matched term-born controls recruited for a regional subsample. Data on hospital admissions, respiratory symptoms, and use of asthma medication was obtained by parental questionnaires at 11 years of age. Questionnaires were returned for 232/372 (62%) EP-born and 57/61 (93%) regional term-born controls. Throughout the study period, 67 (29%) EP-born and seven (13%) term-born controls were admitted to hospital (odds ratio (OR) 2.90, 95% confidence interval (CI): 1.25, 6.72). Admissions were mainly due to surgical procedures, with only 12% due to respiratory causes, and were not influenced by neonatal bronchopulmonary dysplasia (BPD) or low GA(≤ 25 weeks). Respiratory symptoms, asthma and use of asthma medication tended to be more common for EP-born, significantly so for medication use and wheeze on exercise. Neonatal BPD was a risk factor for medication use, but not for current wheeze. In multivariate regression models, home oxygen after discharge (OR 4.84, 95% CI: 1.38, 17.06) and parental asthma (OR 4.38, 95% CI: 1.69, 11.38) predicted current asthma, but neither BPD nor low GA were associated with respiratory symptoms at 11 years of age. Hospitalisation rates five to 11 years after EP birth were low, but twice those of term-born controls, and unrelated to neonatal BPD and low GA. Respiratory causes were rare. Respiratory complaints were more common in children born EP, but the burden of symptoms had declined since early childhood.

A forecasting protocol termed the "prospective approach' was used to examine probable futures relative to coastal applications of satellite data. Significant variables include the energy situation, the national economy, national Earth satellite programs, and coastal zone research, commercial activity, and regulatory activity. Alternative scenarios for the period until 1986 are presented. Possible response by state/local remote sensing centers include operational applications for users, input to geo-base information systems (GIS), development of decision-making algorithms using GIS data, and long term research programs for coastal management using merged satellite and traditional data.

Our aim was to study factors associated with long-term non-recovery from major depression. A total of 109 patients with major depression were followed prospectively for 2 years. A diagnosis of major depression based on SCID interviews at follow-up indicated non-recovery. The effect of several established risk factors was assessed. A third (30%) of the patients did not recover. Severity of initial depression were associated with poor outcome according to univariate analysis. Nevertheless, personality disorder and rural area of residence were associated with non-recovery in final multivariate analysis. Major depression in patients with personality disorder should be treated as effectively as possible. Moreover, service planning in rural areas needs attention.

2018-06-01

Laparoscopic procedures to treat endometrial cancer are currently emerging. At present, we have evidence to do laparoscopic oncologic resections for endometrial cancer as proven by many prospective studies from abroad such as LAP2 by GOG. So, we have decided to assess the safety and feasibility of such a study in our population with the following as our primary objectives: (1) to study whether laparoscopy is better compared to open approach in terms of duration of hospital stay, perioperative morbidity and early recovery from surgical trauma and (2) to study whether the laparoscopic approach is noninferior to the open approach in terms of number of lymph nodes harvested in lymphadenectomy and rate of conversion to open surgery. We did a prospective nonrandomized comparative study of open versus laparoscopy approach for surgical staging of endometrial cancer from 16th May 2013 to 15th May 2015. To prove a significant difference in the hospital stay, we needed 29 patients in each arm. Thirty patients in each arm were enrolled for the study. The median duration of stay in the open arm was 7 days and in the laparoscopy arm it was 5 days. The advantage of 2 days in the laparoscopic arm was statistically significant ( P value 0.006). Forty percent of patients in the open arm had to stay in the hospital for more than 7 days whereas only 3% of patients in the laparoscopy arm required to stay for more than 7 days ( P value 0.001). This difference was statistically significant. There was no significant difference between the early complication rates between the two arms (20% in open vs. 13% in laparoscopy; P value 0.730). There was a conversion rate of 10% in laparoscopy. The median number of nodes harvested in open arm was 16.50 and in the laparoscopy arm, it was 13.50. The difference was not statistically significant ( P value 0.086). Laparoscopy approach for endometrial cancer staging is feasible in Indian patients and the short-term advantages are replicable with same oncologic safety as proved by randomized controlled trials.

Drugs affecting blood pressure variability: an update.

PubMed

Hocht, Christian; Del Mauro, Julieta Sofia; Bertera, Facundo Martín; Taira, Carlos Alberto

2015-01-01

Blood pressure variability (BPV) is considered nowadays a novel risk factor for cardiovascular disease. Clinical evidences support that short-term and long-term BPV independently contribute to target organ damage, cardiovascular events and mortality in patients with hypertension or diabetes. Attenuation of excessive fluctuations of systolic and diastolic BPV has been suggested as an additional therapeutic target in cardiovascular prevention. A growing number of preclinical and clinical studies have focused in the assessment of drug effects or other interventions on the different types of BPV and their contribution in the prevention of cardiovascular events. Prospective clinical trials have shown that antihypertensive classes differ in their ability to control excessive BP fluctuations with an impact in clinical outcomes. Current evidences suggest that calcium channel blockers are more effective than other blood pressure lowering drugs for the reduction of short-term, mid-term and long-term BPV. In order to increase actual knowledge regarding the therapeutic significance of BPV in cardiovascular disease, there is a need for additional clinical studies specifically designed for the study of the relevance of short-term and long-term BPV control by antihypertensive drugs.

2017-01-01

The aim was to examine whether texting on a mobile phone is a risk factor for musculoskeletal disorders in the neck and upper extremities in a population of young adults. In a longitudinal population-based cohort study with Swedish young adults (aged 20-24 years) data were collected via a web-based questionnaire at baseline (n = 7092) and after one and five years. Cross-sectional associations were found between text messaging and reported ongoing symptoms in neck and upper extremities (odds ratios, ORs 1.3-2.0). Among symptom-free at baseline prospective associations were only found between text messaging and new cases of reported symptoms in the hand/fingers (OR 2.0) at one year follow up. Among those with symptoms at baseline prospective associations were found between text messaging and maintained pain in neck/upper back (OR 1.6). The results imply mostly short-term effects, and to a lesser extent, long-term effects on musculoskeletal disorders in neck and upper extremities. Copyright © 2016 The Authors.

2014-08-01

To evaluate the external cephalic version (ECV) procedure for the management of at term breech presenting fetuses. In this prospective, interventional study, 90 patients with uncomplicated breech presentations at or after 37 weeks' gestation were considered for ECV. This was performed in Al-Batool Teaching Hospital, Mosul, Iraq, between January 2011 and March 2012. The main outcome measure was assessed as the success rate of ECV attempt and the rate of cesarean section following a successful procedure. Parity, type of breech, placental location, and birth weight were evaluated as predictors of success. Also, any fetal or maternal complications during the procedure were evaluated. Data were analyzed by x2 test. Statistical significance was determined at a level of p<0.05. The success rate was 80%. The rate of cesarean section following successful procedure was only 12.5%. Prognostic parameters associated with successful ECV were multiparity and flexed type of breech. There were no serious fetal or maternal complications associated with the attempt. With appropriate selection of patients, ECV is highly successful and is a safer alternative to vaginal breech delivery or cesarean delivery.

Health priorities and public preferences: the relative importance of past health experience and future health prospects.

We explore people's choices where the preference for those with worse future health prospects and the preference for the young over the old conflict. The empirical study used scenarios with four attributes: past years, past health, future years without treatment, and future health without treatment. One hundred respondents ranked various patient groups described in these terms. The results suggest a strong effect of past years: younger groups (40-year-olds) were always chosen over older ones (60-year-olds). Past health was significant in one question but not the other and future health and years without treatment were both non-significant.

The purpose of this study was to compare highly cross-linked polyethylene wear between the zirconia head and the cobalt-chromium head in Japanese patients. A prospective, randomized study was performed to evaluate the outcomes in 32 hips that had zirconia heads and in 30 hips that had cobalt-chromium heads. The mean follow-up periods of both groups were same (5 years). There were no significant differences between the zirconia head and the cobalt-chromium head in the mean polyethylene linear wear per year and the mean volumetric polyethylene wear per year in the steady phase. This study indicates that zirconia head offers no benefits over metal head in terms of wear reduction at 5 years in Japanese patients who have lightweight and thin polyethylene liners.

Objective To examine the environmental effects on cytosine methylation of preterm infant's DNA, because early life experiences are considered to influence the physiological and mental health of an individual through epigenetic modification of DNA. Design A prospective cohort study, comparison of epigenetic differences in the glucocorticoid receptor (GR) gene between healthy term and preterm infants. Setting Neonatal Intensive Care Unit in a Japanese University Hospital. Participants A cohort of 40 (20 term and 20 preterm) infants was recruited on the day of birth, and peripheral blood was obtained from each infant at birth and on postnatal day 4. Main outcome measures The methylation rates in the 1-F promoter region of the GR gene using the Mquant method. Results The methylation rate increased significantly between postnatal days 0 and 4 in preterm infants but remained stable in term infants. Thus, the methylation rate was significantly higher in preterm than in term infants at postnatal day 4. Several perinatal parameters were significantly correlated with this change in the methylation rate. Logistic regression analysis revealed that methylation rates at postnatal day 4 predicted the occurrence of later complications that required glucocorticoid administration during the neonatal period. No gene polymorphism was detected within the GR promoter region analysed. Conclusions Although further large-scale studies are needed to detect the environmental factors that explain the difference in epigenetic modification among infants after birth, our data show that the postnatal environment influences epigenetic programming of GR expression through methylation of the GR gene promoter in premature infants, which may result in relative glucocorticoid insufficiency during the postnatal period.

The voice impact of treatment for nonlaryngeal head and neck primary sites remains unknown. We conducted a prospective study of a consecutive sample of patients undergoing chemoradiation for nonlaryngeal head and neck cancer. The Voice Symptom Scale (VoiSS) was completed, and voice recordings were made at 3 time-points. Of 42 recruited patients, 34 completed the measures before and in the early posttreatment phase (mean 16.5 weeks), while 21 patients were assessed at the final time-point (mean, 20.4 months). VoiSS scores showed statistically significant progressive deterioration in the total score (p = .02) and impairment subscale (p < .0001) through to the final assessment. Acoustic measures and perceptual ratings deteriorated significantly (p < .001) in the early posttreatment weeks and improved at the final assessment, but not to the baseline. Interrater agreement was excellent for expert measures. To the best of our knowledge, this is the first prospective study to show that chemoradiation therapy for nonlaryngeal head and neck cancer has a significant effect on the patients' self-reported voice quality, even in the long term.

2016-01-01

From the time Sativex (THC:CBD) oromucosal spray first became available in European Union countries in 2010 for the management of treatment-resistant multiple sclerosis (MS) spasticity, data from daily practice have been collected through various projects. A retrospective registry study and a prospective safety study of THC:CBD oromucosal spray are reported. The most recent analysis of a retrospective registry established in the United Kingdom (UK), Germany and Switzerland, which collected safety data on more than 900 patients, has indicated a positive risk-benefit profile for THC:CBD oromucosal spray during long-term use. Long-term continuation rates were 68% (mean follow-up time 1 year) and the mean dose was 5.4 sprays/day. No new safety concerns were identified, and adverse events of special interest for a cannabis-based medicine were limited. The UK registry has since been closed but remains open in Germany and Switzerland. A prospective safety study undertaken in Spain involved 207 patients from 13 specialized MS centres who had been prescribed THC:CBD oromucosal spray. The findings aligned closely with the UK/German/Swiss registry data in terms of 1-year continuation rates (64.7%), mean daily dose (6.6 sprays/day) and safety profile, including no evidence of addiction, abuse or misuse. The homogeneity between these observational studies supports the interest in THC:CBD oromucosal spray for management of MS spasticity in daily practice. © 2016 S. Karger AG, Basel.

2012-01-01

Background A growing body of empirical evidence indicates that low-level social capital is related to poor mental health outcomes. However, the prospective association between social capital and depression remains unclear, and no published studies have investigated the association with longitudinal data in East-Asian countries. Methods We analyzed data from the ongoing Korean Welfare Panel Study to prospectively investigate association between social capital and depression. Social capital was measured at the individual level by two items specific to interpersonal trust and reciprocity. Depression was annually assessed as a dichotomous variable using the Center for Epidemiologic Studies Depression Scale. After excluding participants who had depression in 2006, logistic regression models were applied to estimate the association between each social capital indicator and new-onset depression developed in 2007 or long-term depression in both 2007 and 2008. We also examined the association in a subpopulation restricted to healthy participants after excluding individuals with any pre-existing disability, chronic disease, or poor self-rated health condition. Results Compared to the high interpersonal trust group, the odds ratios of developing new-onset and long-term depression among the low interpersonal trust group were 1.22 (95% CI: 1.08∼1.38) and 1.23 (95% CI: 1.03∼1.50), respectively, and increased to 1.32 (95% CI: 1.10∼1.57) and 1.47 (95% CI: 1.05∼2.08) in the subpopulation analyses restricted to healthy individuals. Although the low and intermediate reciprocity group also had significantly higher odds of developing new-onset depression compared to the high reciprocity group, the effects were attenuated and statistically non-significant in the subpopulation analyses. Conclusion Low interpersonal trust appears to be an independent risk factor for new-onset and long-term depression in South Korea. PMID:22279597

Objectives The aim of this study was to determine the prospective association of cumulative mechanical exposure during working life with health-related labor market outcomes. Methods This prospective cohort study combines data from 5076 older workers (age 49-63 years) from the Copenhagen Aging and Midlife Biobank with a job exposure matrix and a national register containing information on social transfer payment. By coding individual job histories from the Danish version of ISCO-codes (International Standard Classification of Occupations), we calculated cumulative occupational mechanical exposures from a JEM for ton-years (lifting 1000 kg each day in one year), lifting-years (lifting loads weighing ≥20 kg >10 times each day in one year), kneeling-years (kneeling for one hour each day in one year) and vibration-years (whole-body vibration for one hour each day in one year). Cox-regression analyses estimated the relative risk of register-based long-term sickness absence (LTSA) and disability pension with cumulative occupational mechanical exposures throughout working life. Analyses were censored for competing events and adjusted for multiple confounders. Results During the follow-up period, 970 persons (19.3%) had ≥1 episode of LTSA and 85 persons (1.7%) were granted a disability pension. Number of ton-, lifting- and kneeling-years showed an exposure-response association with increased risk of LTSA (P<0.0001). In addition, both long term [≥20 years; hazard ratio (HR) 1.76 95% CI 1.39-2.22] and short term (<10 years; HR 1.20 95% CI 1.02-1.41) exposure to kneeling work increased the risk of LTSA. Lifting-years, but not the other mechanical exposures, were associated with risk of disability pension (HR 1.75 95% CI 1.01-3.04). Conclusions Cumulative occupational mechanical exposures during working life - such as lifting and kneeling work - increased the risk of LTSA. Importantly, being exposed to lifting increased the risk of disability pension.

To define terms and processes and agree on a minimum dataset in relation to transperineal prostate biopsy procedures and enhanced prostate diagnostics. To identify the need for further evaluation and establish a collaborative research practice. A 19-member multidisciplinary panel rated 66 items for their appropriateness and their definition to be incorporated into the international databank using the Research and Development/University of California Los Angeles Appropriateness Method. The item list was developed from interviews conducted with healthcare professionals from urology, radiology, pathology and engineering. The panel agreed on 56 items that were appropriate to be incorporated into a prospective database. In total, 10 items were uncertain and were omitted. These items were within the categories: definitions (n = 2), imaging (n = 1), surgical protocols (n = 2) and histology (n = 5). The components of a minimum dataset for transperineal prostate biopsy have been defined. This provides an opportunity for multicentre collaborative data analysis and technique development.

2000-12-01

Totally implantable venous access devices (TIVADs) are valuable instruments in case prolonged intravenous therapy is required, but implantation and use of these devices are associated with complications. The purpose of this study was to evaluate perioperative and long-term complications associated with TIVADs. In addition, we compared two different types of TIVADs with respect to implantation, care protocol and patients' comfort. In a retrospective study perioperative and long-term complications in a general oncology population were analysed. In a prospective randomized study comparison of two types of TIVADs was carried out. Perioperative complications occurred in 27 (21.4%) of 126 implanted TIVADs: catheter malposition (16.7%) in 21 patients, pneumothorax (0.8%) in one and haemorrhage (4.0%) in five. Long-term complications appeared in 31 (25.2%) out of 123 TIVADs: thrombosis in 9 (7.3%), especially associated with malposition of the tip of the catheter; infection in 10 (8.1%); extravasation in 2 (1.6%); migration of the catheter tip in 6 (4.8%); pain at reservoir in 3 (2.4%) and inaccessibility of the port in 1 (0.8%). No significant differences were found with respect to implantation, care accessibility and patients' comfort between the two TIVADs. The use of TIVADs is associated with some risk of serious perioperative and long-term complications. In case of thrombotic complications these systems can be saved with appropriate treatment. Correct positioning of the catheter tip is essential to prevent thrombotic complications. In case of TIVAD-related infectious complications, the possibility of saving the TIVAD depends on the causative microorganism and type of infection. Furthermore, to increase patients' satisfaction with TIVADs they should be well informed about the surgical procedure and possible disadvantages of these devices.

Anti-tumour necrosis factor (TNF) agents play a pivotal role in the treatment of moderate to severe ulcerative colitis (UC), and yet, no international consensus on when to discontinue therapy exists. The aim of this study is to study the long-term performance of a treatment algorithm of repeated intensified induction therapy with infliximab (IFX) to remission, followed by discontinuation in patients with UC. Patients with moderate to severe UC were enroled in an open prospective study design. The following algorithm was implemented: (a) intensified induction treatment to remission (Ulcerative Colitis Disease Activity Index score 0-2); (b) discontinuation of IFX; and (c) reinduction treatment if relapse. Mucosal gene expression for TNF was measured with qPCR. A total of 116 patients were included. The median observation time was 47 and 51 months in intention to treat and per protocol. Remission rates of the first three inductions were 95, 93 and 91% per protocol and 83, 56 and 59% by intention to treat. The median time in remission was 40 months per protocol and 34 months by intention to treat. Long-term remission without further anti-TNF treatment during the observation period was obtained for 41%, with a median observation time of 48 months (range: 18-129 months). The median time to relapse was 33 and 11 months with/without normalization of mucosal TNF, respectively. The 5-year success rate for maintaining the effect of IFX in the algorithm was 66%. The treatment algorithm is highly effective for achieving long-term clinical remission in UC. Normalization of mucosal TNF gene expression predicts long-term remission upon discontinuation of IFX.

In recent years, the number of prescriptions for sedative drugs has increased significantly, as has their long-term use. Moreover, sedative use is frequently initiated during hospital stays. This study aimed to describe new prescriptions of sedative drugs during hospital stays and evaluate their maintenance as discharge medication. This observational prospective study took place in an internal medicine ward of a Swiss hospital over a period of 3 months in 2014. Demographic (age, sex, diagnosis, comorbidities) and medication data [long-term use of sedative drugs, new regular or pro re nata ('as needed') prescriptions of sedative drugs, drug-related problems] were collected. Sedative medications included: benzodiazepines, Z-drugs, antihistamines, antidepressants, neuroleptics, herbal drugs, and clomethiazole. McNemar's test was used for comparison. Of 290 patients included, 212 (73%) were over 65 years old and 169 (58%) were women; 34% (n = 98) were using sedative drugs long term before their hospital stay, and 44% (n = 128) had a prescription for sedative drugs at discharge-a 10% increase (p < 0.05). Sedative drugs were newly prescribed to 37% (n = 108) of patients during their stay. Among these, 37% (n = 40) received a repeat prescription at discharge. Over half of the sedative drugs were prescribed within 24 h of admission. Drug-related problems were detected in 76% of new prescriptions, of which 90% were drug-drug interactions. This study showed that hospital stays increased the proportion of patients who were prescribed a sedative drug at discharge by 10% (absolute increase). These prescriptions may generate long-term use and expose patients to drug-related problems. Promoting alternative approaches for managing insomnia are recommended.

The long-pulsed diode (800-810-nm) laser is one of the most commonly used and effective lasers for hair removal. Limitations of currently available devices include a small treatment spot size, treatment-associated pain, and the need for skin cooling. To evaluate the long-term hair reduction capabilities of a long-pulsed diode laser with a large spot size and vacuum assisted suction. Thirty-five subjects were enrolled in a prospective, self-controlled, single-center study of axillary hair removal. The study consisted of three treatments using a long-pulsed diode laser with a large spot size and vacuum-assisted suction at 4- to 6-week intervals with follow-up visits 6 and 15 months after the last treatment. Hair clearance was quantified using macro hair-count photographs taken at baseline and at 6- and 15-month follow-up visits. Changes in hair thickness and color, levels of treatment-associated pain, and adverse events were additional study endpoints. There was statistically significant hair clearance at the 6 (54%) and 15-month (42%) follow-up visits. Remaining hairs were thinner and lighter at the 15-month follow-up visit, and the majority of subjects reported feeling up to mild to moderate pain during treatment without the use of pretreatment anesthesia or skin cooling. A long-pulsed diode laser with a large spot size and vacuum-assisted suction is safe and effective for long-term hair removal. This is the largest prospective study to evaluate long-term hair removal and the first to quantify decreases in hair thickness and darkness with treatment. © 2012 by the American Society for Dermatologic Surgery, Inc.

2016-03-01

The eradication of epileptogenic lesions (e.g. focal cortical dysplasia) can be used for treatment of drug-resistant focal epilepsy, but in highly eloquent cortex areas it can also lead to a permanent neurological deficit. In such cases the neuromodulation effect of low-dose high-precision irradiation of circumscribed lesions may represent an alternative therapy. A total of 10 patients with eloquent localized lesions causing pharmacoresistant focal epilepsy were prospectively identified. After informed consent, six patients agreed and were treated with risk adapted low-dose radiosurgery (SRS) or hypofractionated stereotactic radiotherapy (hfSRT). Comprehensive data concerning treatment modalities and outcome after short-term follow up (mean=16.3 months) were prospectively collected and evaluated. From the six patients, two patients were treated with hfSRT (marginal dose 36 Gy) and four with SRS (marginal dose 13 Gy). Clinical target volume (CTV) ranged from 0.70 ccm to 4.32 ccm. The short-term follow-up ranged from 6 to 27 months. There were no side effects or neurological deficits after treatment. At last available follow-up two patients were seizure-free, one of them being off antiepileptic drugs. The seizure frequency improved in one and remained unchanged in three patients. Treatment of eloquent localized epileptogenic lesions by SRS and hfSRT showed no adverse events and an acceptable seizure outcome in this small prospective patient series. The relatively short-term follow-up comprises one of the study's drawbacks and therefore a longer follow-up should be awaited in order to evaluate the neuromodulation effect of the treatment. These preliminary results may however justify the initiation of a larger prospective trial investigating whether focused low-dose stereotactic irradiation could be an option for lesions in eloquent brain areas.

OBJECTIVE Resection of skull base tumors is challenging. The introduction of alternative treatment options, such as radiotherapy, has sparked discussion regarding outcome in terms of quality of life and neuropsychological deficits. So far, however, no prospective data are available on this topic. METHODS A total of 58 patients with skull base meningiomas who underwent surgery for the first time were enrolled in this prospective single-center trial. The average age of the patients was 56.4 ± 12.5 years. Seventy-nine percent of the tumors were located within the anterior skull base. Neurological examinations and neuropsychological testing were performed at 3 time points: 1 day prior to surgery (T1), 3-5 months after surgery (T2), and 9-12 months after surgery (T3). The average follow-up duration was 13.8 months. Neuropsychological assessment consisted of quality of life, depression and anxiety, verbal learning and memory, cognitive speed, attention and concentration, figural memory, and visual-motor speed. RESULTS Following surgery, 23% of patients showed transient neurological deficits and 12% showed permanent new neurological deficits with varying grades of manifestation. Postoperative quality of life, however, remained stable and was slightly improved at follow-up examinations at T3 (60.6 ± 21.5 vs 63.6 ± 24.1 points), and there was no observed effect on anxiety and depression. Long-term verbal memory, working memory, and executive functioning were slightly affected within the first months following surgery and appeared to be the most vulnerable to impairment by the tumor or the resection but were stable or improved in the majority of patients at long-term follow-up examinations after 1 year. CONCLUSIONS This report describes the first prospective study of neuropsychological outcomes following resection of skull base meningiomas and, as such, contributes to a better understanding of postoperative impairment in these patients. Despite deterioration in a minority of patients on subscales of the measures used, the majority demonstrated stable or improved outcome at follow-up assessments.

The traditional Italian dish pasta is a major food source of starch with low glycemic index (GI) and an important low-GI component of the Mediterranean diet. This systematic review aimed at assessing comprehensively and in-depth the potential benefit of pasta on cardio-metabolic disease risk factors. Following a standard protocol, we conducted a systematic literature search of PubMed, CINAHL, and Cochrane Central Register of Controlled Trials for prospective cohort studies and randomized controlled dietary intervention trials that examined pasta and pasta-related fiber and grain intake in relation to cardio-metabolic risk factors of interest. Studies comparing postprandial glucose response to pasta with that to bread or potato were quantitatively summarized using meta-analysis of standardized mean difference. Evidence from studies with pasta as part of low-GI dietary intervention and studies investigating different types of pasta were qualitatively summarized. Pasta meals have significantly lower postprandial glucose response than bread or potato meals, but evidence was lacking in terms of how the intake of pasta can influence cardio-metabolic disease risk. More long-term randomized controlled trials are needed where investigators directly contrast the cardio-metabolic effects of pasta and bread or potato. Long-term prospective cohort studies with required data available should also be analyzed regarding the effect of pasta intake on disease endpoints.

Radiation-induced xerostomia is one of the most common morbidities of radiation therapy in patients with head and neck cancer. However, in spite of its high rate of occurrence, there are few effective therapies available for its management. The aim of this study was to assess the efficacy of hyperbaric oxygen on the treatment of radiation-induced xerostomia and xerostomia-related quality of life. PubMed, Google Scholar, and the Cochrane Library were searched for retrospective or prospective trials assessing subjective xerostomia, objective xerostomia, or xerostomia-related quality of life. To be included, patients had to have received radiation therapy for head and neck cancer, but not hyperbaric oxygen therapy (HBOT). The systematic review initially identified 293 potential articles. Seven studies, comprising 246 patients, qualified for inclusion. Of the included studies, 6 of 7 were prospective in nature, and 1 was a retrospective study; and 2 of the 7 were controlled studies. HBOT may have utility for treating radiation-induced xerostomia refractory to other therapies. Additionally, HBOT may induce long-term improvement in subjective assessments of xerostomia, whereas other therapies currently available only provide short-term relief. The strength of these conclusions is limited by the lack of randomized controlled clinical trials. Copyright © 2015 Elsevier Inc. All rights reserved.

Little is known about psychological distress as a risk factor for the onset of long-term sickness absence and even less about the influence of fatigue in this relationship. We examined the relationship between psychological distress and the onset of long-term sickness absence during 18 months of follow-up while considering fatigue. Analyses were based on 6403 employees participating in the Maastricht Cohort Study. Psychological distress was related to the onset of long-term sickness absence (women relative risk 1.45, 95% confidence interval = 1.23-1.72; men 1.33, 1.21-1.46). Adjustment for fatigue weakened the associations, particularly in women. Caseness analyses revealed different effects of psychological distress and fatigue in the onset of long-term sickness absence in men and women. The findings underline the need for interventions aiming at psychological distress and, depending on the gender, also at fatigue, to reduce the risk of long-term sickness absence.

Data on dementia prognosis among ethnic minority groups are limited in Europe. We assessed differences in short-term (1-year) and long-term (3-year) mortality and readmission risk after a first hospitalization or first ever referral to a day clinic for dementia between ethnic minority groups and the ethnic Dutch population in the NetherlandsMethods: Nationwide prospective cohorts of first hospitalized dementia patients (N = 55,827) from January 1, 2000 to December 31, 2010 were constructed. Differences in short-term and long-term mortality and readmission risk following hospitalization or referral to the day clinic between ethnic minority groups (Surinamese, Turkish, Antilleans, Indonesians) and the ethnic Dutch population were investigated using Cox proportional hazard regression models with adjustment for age, sex, and comorbidities. Age-sex-adjusted short-term and long-term risks of death following a first hospitalization with dementia were comparable between the ethnic minority groups and the ethnic Dutch. Age- and sex-adjusted risk of admission was higher only in Turkish compared with ethnic Dutch (HR 1.57, 95% CI,1.08-2.29). The difference between Turkish and the Dutch attenuated and was no longer statistically significant after further adjustment for comorbidities. There were no ethnic differences in short-term and long-term risk of death, and risk of readmission among day clinic patients. Compared with Dutch patients with a comparable comorbidity rate, ethnic minority patients with dementia did not have a worse prognosis. Given the poor prognosis of dementia, timely and targeted advance care planning is essential, particularly in ethnic minority groups who are mired by cultural barriers and where uptake of advance care planning is known to be low.

Computed tomography (CT) coronary angiography has been widely used since the introduction of 64-slice scanners and dual-source CT technology, but high radiation doses have been reported. Prospective ECG-gating using a 'step-and-shoot' axial scanning protocol has been shown to reduce radiation exposure effectively while maintaining diagnostic accuracy. 256-slice scanners with 80 mm detector coverage have been currently introduced into practice, but their impact on radiation exposure has not been adequately studied. The aim of this study was to assess radiation doses associated with CT coronary angiography using a 256-slice CT scanner. Radiation doses were estimated for 25 patients scanned with either prospective or retrospective ECG-gating. Image quality was assessed objectively in terms of mean CT attenuation at selected regions of interest on axial coronary images and subjectively by coronary segment quality scoring. It was found that radiation doses associated with prospective ECG-gating were significantly lower than retrospective ECG-gating (3.2 ± 0.6 mSv versus 13.4 ± 2.7 mSv). Consequently, the radiogenic fatal cancer risk for the patient is much lower with prospective gating (0.0176% versus 0.0737%). No statistically significant differences in image quality were observed between the two scanning protocols for both objective and subjective quality assessments. Therefore, prospective ECG-gating using a 'step-and-shoot' protocol that covers the cardiac anatomy in two axial acquisitions effectively reduces radiation doses in 256-slice CT coronary angiography without compromising image quality.

Tumor necrosis factor alpha (TNF-α) inhibitors are linked with increased risk of reactivation of active tuberculosis. The QuantiFERON-TB Gold In-Tube test is approved for screening latent tuberculosis infection in children and adults. There are limited data on the test performance in children on long-term treatment with TNF-α inhibitors. The objective of this study was to assess the proportion of indeterminate results for the QuantiFERON-TB Gold In-Tube in children with inflammatory bowel disease (IBD) on long-term infliximab treatment and to evaluate the range of interferon-γ responses to mitogen. A single-center prospective study of children 5 to 19 years of age with IBD on long-term infliximab treatment (>3 months). Each child was assessed for tuberculosis exposure risk and had blood drawn for the QuantiFERON-TB Gold In-Tube. Data on the range of interferon-γ responses and final QuantiFERON-TB Gold In-Tube test results were collected. Ninety-three children were included, with a median age of 16 years. The median total duration of infliximab therapy was 34 months (range, 3-119 months). The QuantiFERON-TB Gold In-Tube was indeterminate in 1 patient (1.1%), positive in 2 patients, and negative in 90 patients. The maximum interferon-γ response to mitogen (10 IU/mL) was observed in 82 patients (88%), with only 1 patient having an inadequate response. The proportion of indeterminate results was significantly lower than the prospectively hypothesized rate of 8%, based on prior studies in nonimmunosuppressed patients (P = 0.004). Pediatric patients with IBD on long-term treatment with infliximab had an adequate interferon-γ response to mitogen and a low indeterminate rate when assessed with the QuantiFERON-TB Gold In-Tube test. This study demonstrates a robust interferon gamma response to phytohemagglutinin stimulation in a pediatric population on long-term therapy with infliximab. The QuantiFERON-TB Gold In-Tube test may therefore be useful as a periodic screening tactic for latent TB in children on long-term infliximab therapy.

In 2006, the United States Geological Survey (USGS) completed a detailed analysis and interpretation of available 2-D and 3-D seismic data, along with seismic modeling and correlation with specially processed downhole well log data for identifying potential gas hydrate accumulations on the North Slope of Alaska. A methodology was developed for identifying sub-permafrost gas hydrate prospects within the gas hydrate stability zone in the Milne Point area. The study revealed a total of 14 gas hydrate prospects in this area.In order to validate the gas hydrate prospecting protocol of the USGS and to acquire critical reservoir data needed to develop a longer-term production testing program, a stratigraphic test well was drilled at the Mount Elbert prospect in the Milne Point area in early 2007. The drilling confirmed the presence of two prominent gas-hydrate-bearing units in the Mount Elbert prospect, and high quality well logs and core data were acquired. The post-drill results indicate pre-drill predictions of the reservoir thickness and the gas-hydrate saturations based on seismic and existing well data were 90% accurate for the upper unit (hydrate unit D) and 70% accurate for the lower unit (hydrate unit C), confirming the validity of the USGS approach to gas hydrate prospecting. The Mount Elbert prospect is the first gas hydrate accumulation on the North Slope of Alaska identified primarily on the basis of seismic attribute analysis and specially processed downhole log data. Post-drill well log data enabled a better constraint of the elastic model and the development of an improved approach to the gas hydrate prospecting using seismic attributes. ?? 2009.

The aim was to study prospectively primary endoscopic treatment of CBD stones and further the long-term need for renewed gallstone disease interventions, defined as short- and long-term outcome. Seven years prospective follow-up of 101 consecutive patients with CBD stones who underwent endoscopic treatment with the intent of primarily achieving duct clearance. Many patients underwent several endoscopy sessions before stone clearance was completed in 83%. Eleven patients were treated surgically, 2 patients received a permanent stent, and the remaining 3 became stone free with other means. Complications occurred in 47 patients. During follow-up, 31 patients were readmitted for gallstone disease and 15 of these had recurrent CBD stones. Ten percent (8/78) of patients with the gallbladder in situ had acute cholecystitis during follow-up and late cholecystectomy was carried out in 22%. Risk factors for new gallstone disease were an in situ gallbladder containing stones and previous episodes of CBD stones. A goal of complete CBD stone clearance with ERC and ES proved to be relatively resource consuming. Subsequent cholecystectomy after duct clearance for CBD should be advised when the gallbladder lodges gallstones, especially in younger patients. Recurrent CBD stones were not influenced by cholecystectomy.

Species Distribution 2.0: An Accurate Time- and Cost-Effective Method of Prospection Using Street View Imagery

Schwoertzig, Eugénie; Millon, Alexandre

2016-01-01

Species occurrence data provide crucial information for biodiversity studies in the current context of global environmental changes. Such studies often rely on a limited number of occurrence data collected in the field and on pseudo-absences arbitrarily chosen within the study area, which reduces the value of these studies. To overcome this issue, we propose an alternative method of prospection using geo-located street view imagery (SVI). Following a standardised protocol of virtual prospection using both vertical (aerial photographs) and horizontal (SVI) perceptions, we have surveyed 1097 randomly selected cells across Spain (0.1x0.1 degree, i.e. 20% of Spain) for the presence of Arundo donax L. (Poaceae). In total we have detected A. donax in 345 cells, thus substantially expanding beyond the now two-centuries-old field-derived record, which described A. donax only 216 cells. Among the field occurrence cells, 81.1% were confirmed by SVI prospection to be consistent with species presence. In addition, we recorded, by SVI prospection, 752 absences, i.e. cells where A. donax was considered absent. We have also compared the outcomes of climatic niche modeling based on SVI data against those based on field data. Using generalized linear models fitted with bioclimatic predictors, we have found SVI data to provide far more compelling results in terms of niche modeling than does field data as classically used in SDM. This original, cost- and time-effective method provides the means to accurately locate highly visible taxa, reinforce absence data, and predict species distribution without long and expensive in situ prospection. At this time, the majority of available SVI data is restricted to human-disturbed environments that have road networks. However, SVI is becoming increasingly available in natural areas, which means the technique has considerable potential to become an important factor in future biodiversity studies. PMID:26751565

Chocolate intake and diabetes risk.

Greenberg, James A

In-vitro and rodent studies, and short-term human trials suggest that compounds in chocolate can enhance insulin sensitivity. Also, a recent prospective Japanese epidemiological analysis found that long-term chocolate consumption was inversely associated with diabetes risk. The objective of the present analysis was to test the epidemiological association between long-term chocolate consumption and diabetes risk in a U.S. cohort. Multivariable prospective Cox Regression analysis with time-dependent covariates was used to examine data from 7802 participants in the prospective Atherosclerosis Risk in Communities Cohort. The data included 861 new diabetes cases during 98,543 person-years of follow up (mean = 13.3 years). Compared to participants who ate 1 oz of chocolate less often than monthly, those who ate it 1-4 times/month, 2-6 times/week and ≥ 1 time/day had relative risks of being diagnosed with diabetes that were lower by 13% (95% confidence interval: -2%, 25%), 34% (18%, 47%) and 18% (-10%, 38%). These relative risks applied to participants without evidence of preexisting serious chronic disease that included diabetes, heart attacks, stroke or cancer. In conclusion, the risk of diabetes decreased as the frequency of chocolate intake increased, up to 2-6 servings (1 oz) per week. Consuming ≥ 1 serving per day did not yield significantly lower relative risk. These results suggest that consuming moderate amount of chocolate may reduce the risk of diabetes. Further research is required to confirm and explore these findings. Copyright © 2014 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.

Objective To determine the prospective association between retrospectively assessed physical work environment during working life and prospectively assessed sickness absence and labour market exit among older workers. Methods Using Cox regression analyses we estimated the 4-year to 6-year prospective risk of register-based long-term sickness absence (LTSA), disability pension, early retirement and unemployment from exposure to different physical work environmental factors during working life among 5076 older workers (age 49–63 at baseline) from the Copenhagen Aging and Midlife Biobank cohort. Results Very hard physical work throughout working life was a risk factor for LTSA (HR 1.66,95% CI 1.32 to 2.07), disability pension (HR 2.21,95% CI 1.04 to 4.72) and early retirement (HR 1.57,95% CI 1.13 to 2.17). Both short-term (<10 years) and long-term (≥20 years) exposures to lifting or carrying of heavy burdens predicted the risk of LTSA (HRs 1.49–1.56) and disability pension (HRs 2.26–3.29). In contrast, exposure to dust was associated with LTSA and disability pension only following 20 or more exposure years. Conclusions Retrospectively assessed hard physical work during working life and exposure to several factors in the physical work environment, especially heavy lifting, were important for labour market exit and sickness absence. This study underscores the importance of reducing physical work exposures throughout the working life course for preventing sickness absence and premature exit from the labour market. PMID:28819019

Long-Term Quality of Life After Swallowing and Salivary-Sparing Chemo–Intensity Modulated Radiation Therapy in Survivors of Human Papillomavirus–Related Oropharyngeal Cancer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Vainshtein, Jeffrey M.; Moon, Dominic H.; Feng, Felix Y.

Purpose: To evaluate long-term health-related quality of life (HRQOL) in 2 prospective studies of chemo–intensity modulated radiation therapy (chemo-IMRT) for oropharyngeal cancer (OPC). Methods and Materials: Of 93 patients with stage III/IV OPC treated on prospective studies of swallowing and salivary organ-sparing chemo-IMRT, 69 were eligible for long-term HRQOL assessment. Three validated patient-reported instruments, the Head and Neck QOL (HNQOL) questionnaire, the University of Washington quality of life (UWQOL) questionnaire, and the Xerostomia Questionnaire (XQ), previously administered from baseline through 2 years in the parent studies, were readministered at long-term follow-up, along with the Short-Form 36. Long-term changes in HRQOL frommore » before treatment and 2 years were evaluated. Results: Forty patients (58%) with a median follow-up of 6.5 years participated, 39 of whom (97.5%) had confirmed human papillomavirus–positive OPC. Long term, no clinically significant worsening was detected in mean HRQOL scores compared with 2 years, with stable or improved HRQOL from before treatment in nearly all domains. “Moderate” or greater severity problems were uncommon, reported by 5% of patients for eating, 5% for swallowing, and 2.5% and 5% by HNQOL and UWQOL summary scores, respectively. Freedom from percutaneous endoscopic gastrostomy tube dependence and stricture dilation beyond 2 years was 97.5% and 95%, respectively. Eleven percent and 14% of patients reported “moderate” or “severe” long-term worsening in HNQOL Pain and Overall Bother domains, respectively, which were associated with mean dose to the cervical esophagus, larynx, and pharyngeal constrictors. Conclusions: At more than 6 years' median follow-up, OPC patients treated with swallowing and salivary organ-sparing chemo-IMRT reported stable or improved HRQOL in nearly all domains compared with both before treatment and 2-year follow-up. New late toxicity after 2 years was uncommon. Further emphasis on sparing the swallowing organs may yield additional HRQOL gains for long-term OPC survivors.« less

Self-gripping mesh versus fibrin glue fixation in laparoscopic inguinal hernia repair: a randomized prospective clinical trial in young and elderly patients

2016-01-01

Abstract Laparoscopic transabdominal preperitoneal inguinal hernia repair is a safe and effective technique. In this study we tested the hypothesis that self-gripping mesh used with the laparoscopic approach is comparable to polypropylene mesh in terms of perioperative complications, against a lower overall cost of the procedure. We carried out a prospective randomized trial comparing a group of 30 patients who underwent laparoscopic inguinal hernia repair with self-gripping mesh versus a group of 30 patients who received polypropylene mesh with fibrin glue fixation. There were no statistically significant differences between the two groups with regard to intraoperative variables, early or late intraoperative complications, chronic pain or recurrence. Self-gripping mesh in transabdominal hernia repair was found to be a valid alternative to polypropylene mesh in terms of complications, recurrence and postoperative pain. The cost analysis and comparability of outcomes support the preferential use of self-gripping mesh. PMID:28352842

Peer victimization that occurs via electronic media, also termed cybervictimization, is a growing area of concern for adolescents. The current study evaluated the short-term prospective relationship between cybervictimization and adolescents' symptoms of social anxiety and depression over a six-week period. Participants were 839 high-school aged adolescents (14-18 years; 58% female; 73% Hispanic White), who completed measures of traditional peer victimization, cybervictimization, depression, and social anxiety at two time points. Findings supported the distinctiveness of cybervictimization as a unique form of peer victimization. Furthermore, only cybervictimization was associated with increased levels of depressive symptoms over time, and only relational victimization was associated with increased social anxiety over time, after controlling for the comorbidity of social anxiety and depression among youth. Cybervictimization appears to be a unique form of victimization that contributes to adolescents' depressive symptoms and may be important to target in clinical and preventive interventions for adolescent depression.

2015-08-01

Recently, research has provided support for a moderate, inverse relationship between social anxiety and dispositional positive affect. However, the dynamics of this relationship remain poorly understood. The present study evaluates whether certain personality traits and emotion regulation variables predict short-term positive affect for individuals with social anxiety disorder and healthy controls. Positive affect as measured by two self-report instruments was assessed before and after two tasks in which the participant conversed with either a friend or a romantic partner. Tests of models examining the hypothesized prospective predictors revealed that the paths did not differ significantly across diagnostic group and both groups showed the hypothesized patterns of endorsement for the emotion regulation variables. Further, a variable reflecting difficulty redirecting oneself when distressed prospectively predicted one measure of positive affect. Additional research is needed to explore further the role of emotion regulation strategies on positive emotions for individuals higher in social anxiety. Copyright © 2015 Elsevier Ltd.

Young people with drug and alcohol problems are likely to have poorer health and other psychosocial outcomes than other young people. Residential treatment programmes have been shown to lead to improved health and related outcomes for young people in the short term. There is very little robust research showing longer term outcomes or benefits of such programmes. This paper describes an innovative protocol to examine the longer term outcomes and experiences of young people referred to a residential life management and treatment programme in Australia designed to address alcohol and drug issues in a holistic manner. This is a mixed-methods study that will retrospectively and prospectively examine young people's pathways into and out of a residential life management programme. The study involves 3 components: (1) retrospective data linkage of programme data to health and criminal justice administrative data sets, (2) prospective cohort (using existing programme baseline data and a follow-up survey) and (3) qualitative in-depth interviews with a subsample of the prospective cohort. The study will compare findings among young people who are referred and (a) stay 30 days or more in the programme (including those who go on to continuing care and those who do not); (b) start, but stay fewer than 30 days in the programme; (c) are assessed, but do not start the programme. Ethics approval has been sought from several ethics committees including a university ethics committee, state health departments and an Aboriginal-specific ethics committee. The results of the study will be published in peer-reviewed journals, presented at research conferences, disseminated via a report for the general public and through Facebook communications. The study will inform the field more broadly about the value of different methods in evaluating programmes and examining the pathways and trajectories of vulnerable young people.

Background: There is a growing body of evidence that prenatal and early childhood exposure to arsenic from drinking water can have serious long-term health implications. Objectives: Our goal was to understand the potential long-term health and disease risks associated with in utero and early life exposure to arsenic, as well as to examine parallels between findings from epidemiological studies with those from experimental animal models. Methods: We examined the current literature and identified relevant studies through PubMed by using combinations of the search terms “arsenic”, “in utero”, “transplacental”, “prenatal” and “fetal”. Discussion: Ecological studies have indicated associations between in uteromore » and/or early life exposure to arsenic at high levels and increases in mortality from cancer, cardiovascular disease and respiratory disease. Additional data from epidemiologic studies suggest intermediate effects in early life that are related to risk of these and other outcomes in adulthood. Experimental animal studies largely support studies in humans, with strong evidence of transplacental carcinogenesis, atherosclerosis and respiratory disease, as well as insight into potential underlying mechanisms of arsenic's health effects. Conclusions: As millions worldwide are exposed to arsenic and evidence continues to support a role for in utero arsenic exposure in the development of a range of later life diseases, there is a need for more prospective studies examining arsenic's relation to early indicators of disease and at lower exposure levels. - Highlights: • We review in utero and early-life As exposure impacts on lifelong disease risks. • Evidence indicates that early-life As increases risks of lung disease, cancer and CVD. • Animal work largely parallels human studies and may lead to new research directions. • Prospective studies and individual exposure assessments with biomarkers are needed. • Assessing intermediary endpoints may aid early intervention and establish causality.« less

2012-05-01

Few prospective epidemiological studies on soccer match injuries have collected continuous data using subjects from the same group. To investigate long-term injury-induced changes during official matches in the professional Japanese soccer league. Descriptive epidemiological study. Acute injuries during official matches among top-division Japanese professional soccer leaguers were prospectively collected from 1993 to 2007. Injuries preventing player participation for 7 days or more were defined as a reportable injury. Interseasonal variations of injury rate (IR: injuries/1000/player hours) and injury pattern (type, location, circumstances, severity, injury time, positional role, and relationship to weather) were analyzed. Throughout the study period, 2947 injuries from 3984 matches occurred. Mean annual IR was 21.77/1000 player hours, and annual variance showed gradual decrement throughout the study period. The proportion of injury type and location were not significantly changed. Sprain and contusion as injury type and thigh and ankle joint as location were the most common in every season. Contact-related injuries comprised 73.3% on average and were observed to occur more frequently during the last 15 minutes and extra time of match play. The proportion of foul play-related injuries showed a clear declining trend. The proportion of severe injury showed a sporadic increase from 2001 to 2004. The second, fifth, and sixth 15-minute match segments showed a higher IR. Goalkeepers had a lower IR versus other field players. Matches on rainy days resulted in a lower IR than did those held under other weather conditions. Long-term surveillance and statistical feedback of injury characteristics to organization members were considered effective in improving safer play awareness among players and for referees to reduce injury incidence, particularly foul play-related injuries.

Treatment of Chronic Plantar Fasciitis with Noninvasive Interactive Neurostimulation: A Prospective Randomized Controlled Study.

PubMed

Razzano, Cristina; Carbone, Stefano; Mangone, Massimiliano; Iannotta, M Raffaella; Battaglia, Alessandro; Santilli, Valter

The initial treatment of plantar fasciitis should be conservative, with most cases responding to standard physiotherapy, nonsteroidal anti-inflammatory drugs (NSAIDs), heel pads, and stretching. In cases of chronic refractory symptoms, more invasive treatment could be necessary. Noninvasive interactive neurostimulation (NIN) is a form of electric therapy that works by locating areas of lower skin impedance. The objective of the present prospective randomized controlled study was to evaluate whether the use of NIN for chronic plantar fasciitis could result in greater improvement in a foot functional score, lower levels of reported pain, reduced patient consumption of NSAIDs, and greater patient satisfaction compared with electric shockwave therapy in patients without a response to standard conservative treatment. The patients were randomized using random blocks to the NIN program (group 1) or electric shockwave therapy (group 2). The outcome measurements were the pain subscale of the validated Foot Function Index (PS-FFI), patient-reported subjective assessment of the level of pain using a standard visual analog scale, and daily intake of NSAID tablets (etoricoxib 60 mg). The study group was evaluated at baseline (time 0), week 4 (time 1), and week 12 (final follow-up point). Group 1 (55 patients) experienced significantly better results compared with group 2 (49 patients) in term of the PS-FFI score, visual analog scale score, and daily intake of etoricoxib 60 mg. NIN was an effective treatment of chronic resistant plantar fasciitis, with full patient satisfaction in >90% of cases. The present prospective randomized controlled study showed superior results for noninvasive neurostimulation compared with electric shockwave therapy, in terms of the functional score, pain improvement, and use of NSAIDs.

Rydström, Ingela; Dalheim Englund, Lotta; Dellve, Lotta; Ahlstrom, Linda

2017-01-01

The workplace is an essential source of social capital for many people; it provides mutual support and gives meaning to life. However, few prospective studies have thoroughly investigated the importance of aspects of social capital in the workplace. The aim of this study was to investigate the associations between aspects of social capital (social support, sense of community, and quality of leadership) at the workplace, and work ability, working degree, and vitality among women with a history of long-term sick leave from human service organizations. A longitudinal cohort study was performed among women with a history of long-term sick leave. The study started in 2005, and the women were followed up at 6 months, 1 year, and 6 years using self-reported questionnaires (baseline n  = 283). Linear mixed models were used for longitudinal analysis of the repeated measurements of prospective degree of work ability, working degree, and vitality. Analyses were performed with different models; the explanatory variables for each model were social support, sense of community, and quality of leadership and time. Social capital in terms of quality of leadership (being good at solving conflicts and giving high priority to job satisfaction), sense of community (co-operation between colleagues) and social support (help and support from immediate superiors and colleagues) increased the women's work ability score (WAS) as well as working degree over time. Additionally, social capital in terms of quality of leadership increased the women's vitality score over time. A sustainable return-to-work process among individuals with a history of long-term sick leave, going in and out of work participation, could be supported with social support, good quality of leadership, and a sense of community at the workplace. The responsibility for the rehabilitation process can not be reduced to an individual problem, but ought to include all stakeholders involved in the process, such as managers, colleagues, health care services, and the social security agency.

The aim of this prospective study was to evaluate long-term effects of arteriovenous fistula (AVF) on the development of pulmonary arterial hypertension (PAH) and the relationship between blood flow rate of AVF and pulmonary artery pressure (PAP) in the patients with end-stage renal disease (ESRD). This prospective study was performed in 20 patients with ESRD. Before an AVF was surgically created for hemodialysis, the patients were evaluated by echocardiography. Then, an AVF was surgically created in all patients. After mean 23.50 ± 2.25 months, the second evaluation was performed by echocardiography. Also, the blood flow rate of AVF was measured at the second echocardiographic evaluation. Pulmonary arterial hypertension was defined as a systolic PAP above 35 mmHg at rest. Mean age of 20 patients with ESRD was 55.05 ± 13.64 years; 11 of 20 patients were males. Pulmonary arterial hypertension was detected in 6 (30%) patients before AVF creation and in 4 (20%) patients after AVF creation. Systolic PAP value was meaningfully lower after AVF creation than before AVF creation (29.95 ± 10.26 mmHg vs. 35.35 ± 7.86 mmHg, respectively, P: 0.047). However, there was no significant difference between 2 time periods in terms of presence of PAH (P>0.05). Pulmonary artery pressure did not correlate with blood flow rate of AVF and duration after AVF creation (P>0.05). In hemodialysis patients, a surgically created AVF has no significant effect on the development of PAH within a long-term period. Similarly, blood flow rate of AVF also did not affect remarkably systolic PAP within the long-term period. © 2010 The Authors.

Background Antidepressant prescribing continues to rise. Contributing factors are increased long-term prescribing and possibly the use of higher selective serotonin re-uptake inhibitor (SSRI) doses. Aim To review general practice patients prescribed the same antidepressant long-term (≥2 years) and evaluate prescribing and management pre and post-review. Design and setting Prospective observational cohort study using routine data from 78 urban general practices, Scotland. Method All patients prescribed antidepressants (excluding amitriptyline) for ≥2 years were identified from records November 2009 to March 2010. GPs selected patients for face-to-face review of clinical condition and medication, December 2009 to September 2010. Pre- and post-review data were collected; average antidepressant doses and changes in prescribed daily doses were calculated. Onward referral to support services was recorded. Results 8.6% (33 312/388 656) of all registered patients were prescribed an antidepressant, 47.1% (15 689) were defined as long-term users and 2849 (18.2%) were reviewed. 811 (28.5%) patients reviewed had a change in antidepressant therapy: 7.0% stopped, 12.8% reduced dose, 5.3% increased dose, and 3.4% changed antidepressant, resulting in 9.5% (95% CI = 9.1% to 9.8% P<0.001) reduction in prescribed daily dose and 8.1% reduction in prescribing costs. 6.3% were referred onwards, half to NHS Mental Health Services. Pre-review SSRI doses were 10–30% higher than previously reported. Conclusion Almost half of all people prescribed antidepressants were long-term users. Appropriate reductions in prescribing can be achieved by reviewing patients. Higher SSRI doses may be contributing to current antidepressant growth. PMID:23211181

A method for automatic detection of epileptic seizures in long-term scalp-EEG recordings called EpiScan will be presented. EpiScan is used as alarm device to notify medical staff of epilepsy monitoring units (EMUs) in case of a seizure. A prospective multi-center study was performed in three EMUs including 205 patients. A comparison between EpiScan and the Persyst seizure detector on the prospective data will be presented. In addition, the detection results of EpiScan on retrospective EEG data of 310 patients and the public available CHB-MIT dataset will be shown. A detection sensitivity of 81% was reached for unequivocal electrographic seizures with false alarm rate of only 7 per day. No statistical significant differences in the detection sensitivities could be found between the centers. The comparison to the Persyst seizure detector showed a lower false alarm rate of EpiScan but the difference was not of statistical significance. The automatic seizure detection method EpiScan showed high sensitivity and low false alarm rate in a prospective multi-center study on a large number of patients. The application as seizure alarm device in EMUs becomes feasible and will raise the efficiency of video-EEG monitoring and the safety levels of patients.

Executive functions have been argued to be the most vulnerable to brain injury. In providing an analogue of everyday situations amenable to control and management virtual reality (VR) may offer better insights into planning deficits consequent upon brain injury. Here 17 participants with a non-progressive brain injury and reported executive difficulties in everyday life were asked to perform a VR task (working in a furniture storage unit) that emphasised planning, rule following and prospective memory tasks. When compared with an age and IQ-matched control group, the patients were significantly poorer in terms of their strategy, their time-based prospective memory, the overall time required and their propensity to break rules. An examination of sensitivity and specificity of the VR task to group membership (brain-injured or control) showed that, with specificity set at maximum, sensitivity was only modest (at just over 50%). A second component to the study investigated whether the patients' performance could be improved by periodic auditory alerts. Previous studies have demonstrated that such cues can improve performance on laboratory tests, executive tests and everyday prospective memory tasks. Here, no significant changes in performance were detected. Potential reasons for this finding are discussed, including symptom severity and differences in the tasks employed in previous studies.

To perform a dose-response meta-analysis of prospective cohort studies investigating the association between long-term coffee intake and risk of hypertension. An online systematic search of studies published up to November 2016 was performed. Linear and non-linear dose-response meta-analyses were conducted; potential evidence of heterogeneity, publication bias, and confounding effect of selected variables were investigated through sensitivity and meta-regression analyses. Seven cohorts including 205,349 individuals and 44,120 cases of hypertension were included. In the non-linear analysis, there was a 9% significant decreased risk of hypertension per seven cups of coffee a day, while, in the linear dose-response association, there was a 1% decreased risk of hypertension for each additional cup of coffee per day. Among subgroups, there were significant inverse associations for females, caffeinated coffee, and studies conducted in the US with longer follow-up. Analysis of potential confounders revealed that smoking-related variables weakened the strength of association between coffee consumption and risk of hypertension. Increased coffee consumption is associated with a modest decrease in risk of hypertension in prospective cohort studies. Smoking status is a potential effect modifier on the association between coffee consumption and risk of hypertension.

On December 1, 2015, the Japanese government launched the Stress Check Program, a new occupational health policy to screen employees for high psychosocial stress in the workplace. As only weak evidence exists for the effectiveness of the program, we sought to estimate the risk of stress-associated long-term sickness absence as defined in the program manual. Participants were 7356 male and 7362 female employees in a financial service company who completed the Brief Job Stress Questionnaire (BJSQ). We followed them for 1 year and used company records to identify employees with sickness absence of 1 month or longer. We defined high-risk employees using the BJSQ and criteria recommended by the program manual. We used the Cox proportional regression model to evaluate the prospective association between stress and long-term sickness absence. During the follow-up period, we identified 34 male and 35 female employees who took long-term sickness absence. After adjustment for age, length of service, job type, position, and post-examination interview, hazard ratios (95% confidence intervals) for incident long-term sickness absence in high-stress employees were 6.59 (3.04-14.25) for men and 2.77 (1.32-5.83) for women. The corresponding population attributable risks for high stress were 23.8% (10.3-42.6) for men and 21.0% (4.6-42.1) for women. During the 1-year follow-up, employees identified as high stress (as defined by the Stress Check Program manual) had significantly elevated risks for long-term sickness absence.

Consumption of wine has a protective effect on cardiovascular diseases. Data from prospective, long-term, head-to-head comparisons of effects of different drinks on markers of atherosclerosis have been insufficient. In Vino Veritas (IVV) study is long-term, prospective, multi-centre, randomized trial comparing effects of red and white wine on atherosclerosis. 157 healthy subjects were randomized to white or red wine consumption for one year. We did not find increase in HDL-cholesterol in the whole group (1.66±0.58 vs 1.62±0.49, p=0.180) or difference between both groups (1.60±0.53 vs 1.64±0.46, p=0.634). At 12 months there was reduction of LDL-cholesterol in both groups, but with no difference between the groups (3.37±0.75 vs 3.60±1.10, p=0.134); there was no difference between the groups in total cholesterol, CRP, fasting blood glucose and liver function tests. Both groups had comparable differences from baseline in levels of parameters of oxidative stress. We did not find any clinically relevant differences in the lipid profile, CRP, fasting blood glucose and other markers of atherosclerosis, between long-term consumption of red and white wine. Moreover, we were unable to confirm the hypothesis that wine drinking is associated with an elevation of HDL (Tab. 7, Fig. 1, Ref. 30).

Hypertension and diabetes mellitus are common comorbidities of colorectal cancer. We designed a prospective cohort study aiming to investigate the impact of long-term antihypertensive and antidiabetic medications on colorectal cancer-specific survival and recurrence among 713 post-surgical patients. All participants received radical resection for colorectal cancer during 2000-08, and they were followed up until July 2017. Colorectal cancer patients without hypertension had better survival than those with hypertension (median survival time [MST]: 190.3 months versus 99.0 months, p <0.001). The impact of antidiabetic medications on prolonging colorectal cancer survival was statistically significant, that is, patients receiving antidiabetic medications had longer survival time than untreated diabetic patients (MST: 135.8 months versus 80.2 months, p : 0.007), whereas the prognosis was greatly improved in colorectal cancer patients without diabetes mellitus ( p <0.001). Medical treatment for hypertension and diabetes mellitus was associated with 28% (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.47-1.10; p : 0.131) and 57% (HR: 0.43; 95% CI: 0.22-0.82; p : 0.010) reduced risk of dying from colorectal cancer relative to those without medications, respectively. Our data indicate that long-term antidiabetic medications can significantly prolong the survival and improve the prognosis of post-surgical colorectal cancer.

The left internal mammary artery (LIMA) graft is considered the "gold standard" of coronary artery bypass grafting (CABG). This conduit provides increased survival, symptomatic relief, increased freedom from myocardial infarction, and increased freedom from re-intervention when compared to saphenous venous grafting. It has a remarkable long term patency rate with clinical and angiographic outcomes that are unmatched by other conduits. Given the fact that patients often require more than one graft during a coronary revascularization procedure, the prospect of bilateral internal mammary artery (BIMA) grafting has been very appealing to some surgeons. BIMA grafting has been extensively studied via multiple retrospective and prospective cohort studies and findings have indicated that BIMA grafting can have an increased survival benefit when compared to LIMA grafting alone. As a result, this technique has accrued increasing popularity over the course of the last decade. Yet, questions still remain on whether BIMA grafting is the optimal treatment modality for patients in terms of long-term prognosis. There is limited data at the present time from randomized controlled trials and only 4-12% of CABGs performed today utilize BIMA grafting. Concerns regarding perioperative complications, which patient subsets are at higher risks for complications from the technique, and the technical challenges involved in utilizing and teaching the technique have limited its widespread use.

[Intensive care medicine-survival and prospect of life].

PubMed

Valentin, A

2017-10-01

Intensive care medicine has achieved a significant increase in survival rates from critical illness. In addition to short-term outcomes like intensive care unit or hospital mortality, long-term prognosis and prospect of life of intensive care patients have recently become increasingly important. Pure survival is no longer a sole goal of intensive care medicine. The prediction of an intensive care patient's individual course should include the period after intensive care. A relevant proportion of all intensive care patients is affected by physical, psychological, cognitive, and social limitations after discharge from the intensive care unit. The prognosis of the status of the patient after discharge from the intensive care unit is an important part of the decision-making process with respect to the implementation or discontinuation of intensive care measures. The heavy burden of intensive care treatment should not solely be argued by pure survival but an anticipated sound prospect of life.

Optimal execution with price impact under Cumulative Prospect Theory

Optimal execution of a stock (or portfolio) has been widely studied in academia and in practice over the past decade, and minimizing transaction costs is a critical point. However, few researchers consider the psychological factors for the traders. What are traders truly concerned with - buying low in the paper accounts or buying lower compared to others? We consider the optimal trading strategies in terms of the price impact and Cumulative Prospect Theory and identify some specific properties. Our analyses indicate that a large proportion of the execution volume is distributed at both ends of the transaction time. But the trader's optimal strategies may not be implemented at the same transaction size and speed in different market environments.

Since 1995, the USGS has developed an annual list of 100 noteworthy prospects that were considered to have a high level of potential for near-term development based on such criteria as intensity of drilling, level of capital investment, and size of resource. This study reviews the status of the U.S. sites included on these lists as of July 2011 and addresses domestic prospects not included on the lists that have come into production since 1995.

Relatively little is known about the effects of mode of delivery on long-term health-related quality-of-life outcomes. Furthermore, no previous study has expressed these outcomes in preference-based (utility) metrics. The study population comprised 2,161 mothers recruited from a prospective population-based study in the East Midlands of England encompassing live births and stillbirths between 32 +0 and 36 +6 weeks' gestation and a sample of term-born controls. Perinatal data were extracted from the mothers' maternity records. Health-related quality-of-life outcomes were assessed at 12 months postpartum, using the EuroQol Five Dimensions (EQ-5D) measure with responses to the EQ-5D descriptive system converted into health utility scores. Descriptive statistics and multivariable analyses were used to estimate the relationship between the mode of delivery and health-related quality-of-life outcomes. The overall health-related quality-of-life profile of the women in the study cohort mirrored that of the English adult population as revealed by national health surveys. A significantly higher proportion of women delivering by cesarean delivery reported some, moderate, severe, or extreme pain or discomfort at 12 months postpartum than women undergoing spontaneous vaginal delivery. Multivariable analyses, using the Ordinary Least Squares estimator revealed that, after controlling for maternal sociodemographic characteristics, cesarean delivery without maternal or fetal compromise was associated with a significant EQ-5D utility decrement in comparison to spontaneous vaginal delivery among all women (-0.026; p = 0.038) and among mothers of term-born infants (-0.062; p < 0.001). Among mothers of term-born infants, this result was replicated in models that controlled for all maternal and infant characteristics (utility decrement of -0.061; p < 0.001). The results were confirmed by sensitivity analyses that varied the categorization of the main exposure variable (mode of delivery) and the econometric strategy. Among mothers of term-born infants, cesarean delivery without maternal or fetal compromise is associated with poorer long-term health-related quality of life in comparison to spontaneous vaginal delivery. Further longitudinal studies are needed to understand the magnitude, trajectory, and underpinning mechanisms of health-related quality-of-life outcomes following different modes of delivery. © 2016 Wiley Periodicals, Inc.

We sought to analyze whether maternal intravenous fluid therapy prior to external cephalic version (ECV) increases the amount of amniotic fluid and the success rate of the procedure. This was a prospective single-center cohort study of 200 women with a consecutive cohort of 100 pregnant women with a breech presentation at term who were administered intravenous fluid therapy with 2 L of hypotonic saline before the version attempt, compared to a control cohort of 100 pregnant women not given hydration treatment. The mean increase in the amniotic fluid index (AFI) after intravenous maternal hydration was 3.75 ± 2.71 cm. The amount of fluid before hydration was the only variable found to be associated with increases in amniotic fluid levels, both in absolute and relative terms (odds ratio, -0.21; 95% confidence interval, -0.37 to -0.05 and odds ratio, -4.62; 95% confidence interval, -6.17 to -3.06; P < .01, respectively). We did not observe any severe complications secondary to the intravenous fluid therapy. The ECV success rate was 43% in the study group compared to 47% in the control group (P = .67). The success rate was significantly lower the larger the relative increase in the AFI, although no correlation was found in absolute terms (χ(2) for linear trend = 0.03 and 0.34, respectively). Maternal intravenous fluid therapy with 2 L of hypotonic saline prior to ECV is an effective and safe technique for increasing the AFI. However, its use in ECV does not increase the success rate of the procedure. Copyright © 2014 Elsevier Inc. All rights reserved.

Negative physical and psychological long-term consequences of abuse and bullying are well documented. It is reasonable to assume that abuse and bullying early in life also may have an impact on the ability to work and stay economically independent later in life, but such prospective studies are lacking. This study investigates the consequences of exposure to abuse and bullying in junior high school, as measured by receiving long-term social welfare benefits in young adulthood. In addition, it explores the potential protective role of social support. Self-reported data from 13,633 (50.3% female) junior high school students were linked to registry data on their use of social welfare benefits from the age of 18 and for eight consecutive years. Cox regression analyses were applied to test the relationship between exposure to life adversities and the use of social welfare benefits, and the potential moderating role of social support. The analyses showed that individuals exposed to abuse and bullying had an increased likelihood of receiving social-welfare benefits compared with individuals not exposed to these types of abuse. Exposure to multiple types of abuse led to a higher likelihood of using social welfare benefits compared with single types of abuse and no abuse. The findings on the potential moderating role of social support were mixed, depending on the source of social support. Family support and classmate relationships were protective in reducing the likelihood of the use of social welfare benefits, whereas peer and teachers' support showed inconsistent patterns. These results are promising in terms of preventing the long-term negative consequences of abuse and bullying.

Pre-deployment identification of soldiers at risk for long-term posttraumatic stress psychopathology after home coming is important to guide decisions about deployment. Early post-deployment identification can direct early interventions to those in need and thereby prevents the development of chronic psychopathology. Both hold significant public health benefits given large numbers of deployed soldiers, but has so far not been achieved. Here, we aim to assess the potential for pre- and early post-deployment prediction of resilience or posttraumatic stress development in soldiers by application of machine learning (ML) methods. ML feature selection and prediction algorithms were applied to a prospective cohort of 561 Danish soldiers deployed to Afghanistan in 2009 to identify unique risk indicators and forecast long-term posttraumatic stress responses. Robust pre- and early postdeployment risk indicators were identified, and included individual PTSD symptoms as well as total level of PTSD symptoms, previous trauma and treatment, negative emotions, and thought suppression. The predictive performance of these risk indicators combined was assessed by cross-validation. Together, these indicators forecasted long term posttraumatic stress responses with high accuracy (pre-deployment: AUC = 0.84 (95% CI = 0.81-0.87), post-deployment: AUC = 0.88 (95% CI = 0.85-0.91)). This study utilized a previously collected data set and was therefore not designed to exhaust the potential of ML methods. Further, the study relied solely on self-reported measures. Pre-deployment and early post-deployment identification of risk for long-term posttraumatic psychopathology are feasible and could greatly reduce the public health costs of war.

Background: Established causes of diabetes do not fully explain the present epidemic. High-level arsenic exposure has been implicated in diabetes risk, but the effect of low-level arsenic exposure in drinking water remains unclear. Objective: We sought to determine whether long-term exposure to low-level arsenic in drinking water in Denmark is associated with an increased risk of diabetes using a large prospective cohort. Methods: During 1993–1997, we recruited 57,053 persons. We followed each cohort member for diabetes occurrence from enrollment until 31 December 2006. We traced and geocoded residential addresses of the cohort members and used a geographic information system to link addresses with water-supply areas. We estimated individual exposure to arsenic using all addresses from 1 January 1971 until the censoring date. Cox proportional hazards models were used to model the association between arsenic exposure and diabetes incidence, separately for two definitions of diabetes: all cases and a more strict definition in which cases of diabetes based solely on blood glucose results were excluded. Results: Over a mean follow-up period of 9.7 years for 52,931 eligible participants, there were a total of 4,304 (8.1%) diabetes cases, and 3,035 (5.8%) cases of diabetes based on the more strict definition. The adjusted incidence rate ratios (IRRs) per 1-μg/L increment in arsenic levels in drinking water were as follows: IRR = 1.03 (95% CI: 1.01, 1.06) and IRR = 1.02 (95% CI: 0.99, 1.05) for all and strict diabetes cases, respectively. Conclusions: Long-term exposure to low-level arsenic in drinking water may contribute to the development of diabetes.

Mental health and abortion: review and analysis.

PubMed

Ney, P G; Wickett, A R

1989-11-01

This survey of studies which relate to the emotional sequelae of induced abortion, draws attention to the need for more long-term, in-depth prospective studies. The literature to this point finds no psychiatric indications for abortion, and no satisfactory evidence that abortion improves the psychological state of those not mentally ill; abortion is contra-indicated when psychiatric disease is present, as mental ill-health has been shown to be worsened by abortion. Recent studies are turning up an alarming rate of post-abortion complications such as P.I.D., and subsequent infertility. The emotional impact of these complications needs to be studied. Other considerations looked at are the long-term demographic implications of abortion on demand and the effect on the medical professions.

Fatigue is a common symptom with numerous causes. Severe fatigue is thought to be an important manifestation of post-treatment Lyme disease syndrome. The frequency with which severe fatigue occurs as a long-term sequela in prospectively followed patients with Lyme disease is unknown. Patients with culture-confirmed Lyme disease who originally presented with erythema migrans have been evaluated annually in a prospective study to determine their long-term outcome. In 2011-2013, subjects were evaluated for fatigue using an 11-item Fatigue Severity Scale (FSS-11) that has been used in studies of post-treatment Lyme disease syndrome. An FSS-11 score of ≥4.0 is indicative of severe fatigue. A total of 100 subjects were assessed, 52% of whom were male; the mean age was 64.9 years (range, 42-86 years). The mean duration of follow-up was 15.4 years (range, 11-20 years). Nine subjects had severe fatigue but in none as a consequence of Lyme disease. Only 3 subjects were thought to possibly have persistent fatigue from Lyme disease. The FSS-11 value for these 3 individuals was less than 4, averaging 2.27, and none had functional impairment. Severe fatigue was found in 9 patients (9%) with culture-confirmed early Lyme disease at 11 to 20 years after presentation, but was due to causes other than Lyme disease. Fatigue of lesser severity was possibly due to Lyme disease, but was found in only 3% of 100 patients, and therefore is rarely a long-term complication of this infection.

There is limited knowledge about what happens to people after long-term sick leave. The aim of this report was to conduct a prospective study of individuals who were on prolonged sick leave during a particular year, considering their activities and sources of income during subsequent years. To enable comparison of different time periods, we used three cohorts of individuals with different starting years. Using data from national registers, three separate cohorts were constructed that included all people living in Sweden who were 20-64 years of age (>5 million) in the years 1995, 2000 and 2005, respectively. The individual members of the cohorts were classified into the following groups based on their main source of income and activity in 1995-2008: on long-term sick leave, employed, old-age pensioner, long-term unemployed, disability pensioner, on parental leave, social assistance recipient, student allowance recipient, deceased, or emigrated. Most individuals on long-term (> 6 months) sick leave in 1995 were not employed 13 years later. Only 11% of the women and 13% of the men were primarily in employment after 13 years. Instead, a wide range of alternatives existed, for example, many had been granted disability pension, and about 10% of the women and 17% of the men had died during the follow-up period. A larger proportion of those with long-term sick leave were back in employment when 2005 was the starting year for the follow-up. The low future employment rates for people on long-term sick leave may seem surprising. There are several possible explanations for the finding: The disorders these people may have, might have entailed longstanding difficulties on the labor market. Besides, long-term absence from work, no matter what its causes were, might have worsen the chances of further employment. The economic cycles may also have been of importance. The improving labor market during later years seems to have improved the chances for employment among those earlier on long-term sick leave.

Newly diagnosed patients with cancer require education about the disease, the available treatments and potential consequences of treatment. Greater understanding of cancer risk has been found to be associated with greater health-related quality of life, improved psychological adjustment and greater health-related behaviours. The aim of this sytematic review was to assess the effectiveness of educational interventions in improving subjective cancer risk perception and to appraise the quality of the studies. We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) and prospective observational studies. Eligible studies were identified via Medline, PsycINFO, AMED, CINAHL and Embase databases. After screening titles and abstracts, two reviewers independently assessed the eligibility of 206 full-text articles. Forty papers were included in the review; the majority of studies were conducted among breast cancer patients (n = 29) and evaluated the effect of genetic counselling on personal perceived risk (n = 25). Pooled results from RCTs (n = 12) showed that, both in the short and long term, educational interventions did not significantly influence risk perception level (standardised mean difference 0.05, 95% CI -0.24-0.34; p = 0.74) or accuracy (odds ratio = 1.96, 95% CI: 0.61-6.25; p = 0.26). Only one RCT reported a short-term difference in risk ratings (p = 0.01). Of prospective observational studies (n = 28), many did demonstrate changes in the level of perceived risk and improved risk accuracy and risk ratings in both the short and long term. However, only one (of three) observational studies reported a short-term difference in risk ratings (p < = 0.003). Further development and investigation of educational interventions using good quality, RCTs are warranted. Copyright © 2014 John Wiley & Sons, Ltd.

Long-term Response of Cerebrospinal Fluid Pressure in Patients with Idiopathic Intracranial Hypertension - A Prospective Observational Study.

PubMed

Gafoor, V Abdul; Smita, B; Jose, James

2017-01-01

Idiopathic intracranial hypertension (IIH) is increased intracranial pressure (ICP) with normal cerebrospinal fluid (CSF) contents, in the absence of an intracranial mass, hydrocephalus, or other identifiable causes. The current knowledge of the treatment outcome of IIH is limited, and the data on the natural history of this entity are scant. The objective of the study is to study the treatment response of IIH by serially measuring the CSF opening pressure and to delineate the factors influencing the same. A prospective observational study in a cohort of fifty patients with IIH in whom CSF opening pressure was serially measured at pre-specified intervals. The mean CSF opening pressure at baseline was 302.4 ± 51.69 mm of H 2 O (range: 220-410). Even though a higher body mass index (BMI) showed a trend toward a higher CSF opening pressure, the association was not significant ( P = 0.168). However, the age of the patient had a significant negative correlation with the CSF pressure ( P = 0.006). The maximum reduction in CSF pressure occurred in the first 3 months of treatment, and thereafter it plateaued. Remission was attained in 12 (24%) patients. BMI had the strongest association with remission ( P = 0.001). In patients with IIH, treatment response is strongly related to BMI. However, patients with normal BMI are also shown to relapse and hence should have continuous, long-term follow-up. The reduction in CSF pressure attained in the first 3 months could reflect the long-term response to treatment.

It is generally assumed that the elderly patients are more vulnerable to cognitive side effects after electroconvulsive therapy (ECT) than younger depressed patients. The current study aims to evaluate the nature and extent of changes across multiple domains of neurocognitive functioning in a group of elderly depressed patients after ECT. In this prospective naturalistic study, we included 42 depressed patients aged ≥55 years. Global cognitive function, memory, and executive function were assessed before ECT treatment and within one week (short-term post-ECT) and six months after ECT (long-term post-ECT). Associations between cognitive functioning and electrode placement, total number of treatment sessions, age, and the severity of depression at the time of cognitive measurement were studied. Our data offered no evidence of decline for any of the neurocognitive tests after ECT, given its power to detect the difference. Post-ECT improvement of neurocognitive functioning was statistically significant for the Mini-Mental State Examination, Visual Association Test, 10 Words Verbal Learning Test, and Expanded Mental Control Test. Effect sizes were medium to large. After six months, compared with post-ECT performance, statistically significant improvement was found only for the Trail Making Test-A and the Letter Fluency Test with small to medium effect sizes. In our severely depressed elderly patients, neurocognitive performance improved or did not change after ECT. Patients with poor cognitive function were not able to participate in neuropsychological assessment before ECT started. Consequently these results may not apply to patients with more severe cognitive impairment prior to the start of ECT.

Advancing the long view of ecological change in tundra systems

Despite uncertainties related to sustained funding, ideological rivalries and the turnover of research personnel, long-term studies and studies espousing a long-term perspective in ecology have a history of contributing landmark insights into fundamental topics, such as population- and community dynamics, species interactions and ecosystem function. They also have the potential to reveal surprises related to unforeseen events and non-stationary dynamics that unfold over the course of ongoing observation and experimentation. The unprecedented rate and magnitude of current and expected abiotic changes in tundra environments calls for a synthetic overview of the scope of ecological responses these changes have elicited. In this special issue, we present a series of contributions that advance the long view of ecological change in tundra systems, either through sustained long-term research, or through retrospective or prospective modelling. Beyond highlighting the value of long-term research in tundra systems, the insights derived herein should also find application to the study of ecological responses to environmental change in other biomes as well.

A modern competency-based medical education is well implemented globally, but less is known about how the included learning activities contribute to medical students' professional development. The aim of this study was to explore Swedish medical students' perceptions of the offered learning activities and their experiences of how these activities were connected to their professional development as defined by the CanMEDS framework. A prospective mixed method questionnaire study during three terms (internal medicine, scientific project, and surgery) in which data were collected by using contextual activity sampling system, i.e., the students were sent a questionnaire via their mobile phones every third week. All 136 medical students in the 6th of 11 terms in the autumn of 2012 were invited to participate. Seventy-four students (54%) filled in all of the required questionnaires (4 per term) for inclusion, the total number of questionnaires being 1335. The questionnaires focused on the students' experiences of learning activities, especially in relation to the CanMEDS Roles, collaboration with others and emotions (positive, negative, optimal experiences, i.e., "flow") related to the studies. The quantitative data was analysed statistically and, for the open-ended questions, manifest inductive content analysis was used. Three of the CanMEDs Roles, Medical Expert, Scholar, and Communicator, were most frequently reported while the four others, e.g., the role Health Advocate, were less common. Collaboration with students from other professions was most usual during the 8th term. Positive emotions and experience of "flow" were most often reported during clinical learning activities while the scientific project term was connected with more negative emotions. Our results showed that it is possible, even during clinical courses, to visualise the different areas of professional competence defined in the curriculum and connect these competences to the actual learning activities. Students halfway through their medical education considered the most important learning activities for their professional development to be connected with the Roles of Medical Expert, Scholar, and Communicator. Given that each of the CanMEDS Roles is at least moderately important during undergraduate medical education, the entire spectrum of the Roles should be emphasised and developed during the clinical years.

Prospective risk analysis prior to retrospective incident reporting and analysis as a means to enhance incident reporting behaviour: a quasi-experimental field study.

Hospitals can apply prospective and retrospective methods to reduce the large number of medical errors. Retrospective methods are used to identify errors after they occur and to facilitate learning. Prospective methods aim to determine, assess and minimise risks before incidents happen. This paper questions whether the order of implementation of those two methods influences the resultant impact on incident reporting behaviour. From November 2007 until June 2008, twelve wards of two Dutch general hospitals participated in a quasi-experimental reversed-treatment non-equivalent control group design. The six units of Hospital 1 first conducted a prospective analysis, after which a sophisticated incident reporting and analysis system was implemented. On the six units of Hospital 2 the two methods were implemented in reverse order. Data from the incident reporting and analysis system and from a questionnaire were used to assess between-hospital differences regarding the number of reported incidents, the spectrum of reported incident types, and the profession of reporters. The results show that carrying out a prospective analysis first can improve incident reporting behaviour in terms of a wider spectrum of reported incident types and a larger proportion of incidents reported by doctors. However, the proposed order does not necessarily yield a larger number of reported incidents. This study fills an important gap in safety management research regarding the order of the implementation of prospective and retrospective methods, and contributes to literature on incident reporting. This research also builds on the network theory of social contagion. The results might indicate that health care employees can disseminate their risk perceptions through communication with their direct colleagues. Copyright 2010 Elsevier Ltd. All rights reserved.

To investigate the non-inferiority of postoperative single-dose intravenous antimicrobial prophylaxis to multiple-dose intravenous antimicrobial prophylaxis in terms of the incidence of surgical site infections (SSIs) in patients undergoing elective rectal cancer surgery by a prospective randomized study. Patients undergoing elective surgery for rectal cancer were randomized to receive a single intravenous injection of flomoxef (group 1) or five additional doses (group 2) of flomoxef after the surgery. All the patients had received preoperative oral antibiotic prophylaxis (kanamycin and erythromycin) after mechanical cleansing within 24 h prior to surgery, and had received intravenous flomoxef during surgery. A total of 279 patients (including 139 patients in group 1 and 140 in group 2) were enrolled in the study. The incidence of SSIs was 13.7% in group 1 and 13.6% in group 2 (difference [95% confidence interval]: -0.2% [-0.9 to 0.7%]). The incidence of SSIs was not significantly different in patients undergoing elective rectal surgery who were treated using a single dose of postoperative antibiotics compared to those treated using multiple-dose antibiotics when preoperative mechanical and chemical bowel preparations were employed.

Of the positive studies, 12 were consistent with Level I evidence, 3 with Level II evidence, and 5 with Level IV evidence. Specific resistance training (SRT) exercise appeared to be associated with more positive studies (eight Level I studies) than other exercise modalities such as general resistance training, general physical exercise, stretching, and movement awareness exercises. Studies of longer trial duration tended toward more null findings and lower program compliance. Evidence for a primary preventive effect of workplace exercise is minimal. The findings of this review suggest that workplace exercise can be effective as tertiary prevention and therapeutic relief of neck/shoulder symptoms, at least over the shorter term. PMID:25780338

Fingolimod (Gilenya) is an oral medication for patients with highly active relapsing-remitting Multiple Sclerosis (RRMS). Clinical trials and post-marketing experience on more than 114,000 patients have established a detailed safety profile. Total patient exposure now exceeds 195,000 patient-years as stated in the last financial report (Dec 2014) of the Novartis Pharma AG, Basel, Switzerland. However, less is known about the safety of long-term fingolimod use in daily practice. Here, we describe the study design of PANGAEA (Post-Authorization Non-interventional German sAfety of GilEnyA in RRMS patients), a prospective, multicenter, non-interventional, long-term study to collect safety, efficacy, and pharmacoeconomic data on RRMS patients treated with fingolimod (0.5 mg/daily) under real-world conditions in Germany. PANGAEA is striving to assess a real-world safety and efficacy profile of fingolimod, based on data from 4,000 RRMS patients, obtained during a 60-month observational phase. A pharmacoeconomic sub-study of 800 RRMS patients further collects patient-reported outcome measures of disability, quality of life, compliance, treatment satisfaction, and usage of resources during a 24-month observational phase. Descriptive statistical analyses of the safety set as well as of stratified subgroups such as patients with concomitant diabetes mellitus and pretreated patients (e.g., natalizumab) will be conducted. PANGAEA seeks to confirm the current safety profile of fingolimod obtained in phase I-III clinical trials. The study design presented here will additionally provide guidance on the therapeutic use of fingolimod in clinical practice and possibly assists physicians in making evidence-based decisions.

Increased fruit and vegetable intake lowers blood pressure in short-term interventional studies. However, data on the association of long-term intake of fruits and vegetables with hypertension risk are scarce. We prospectively examined the independent association of whole fruit (excluding juices) and vegetable intake, as well as the change in consumption of whole fruits and vegetables, with incident hypertension in three large longitudinal cohort studies: Nurses’ Health Study (n=62,175), Nurses’ Health Study II (n=88,475), and Health Professionals Follow-up Study (n =36,803). We calculated hazard ratios and 95% confidence intervals for fruit and vegetable consumption while controlling for hypertension risk factors. Compared with participants whose consumption was ≤4servings/week, the pooled hazard ratios among those whose intake was ≥4servings/day were 0.92(0.87–0.97) for total whole fruit intake and 0.95(0.86–1.04) for total vegetable intake. Similarly, compared with participants who did not increase their fruit or vegetable consumption, the pooled hazard ratios for those whose intake increased by ≥7servings/week were 0.94(0.90–0.97) for total whole fruit intake and 0.98(0.94–1.01) for total vegetable. Analyses of individual fruits and vegetables yielded different results. Consumption levels of ≥4servings/per week (as opposed to <1serving/month) of broccoli, carrots, tofu or soybeans, raisins and apples was associated with lower hypertension risk. In conclusion, our results suggest that greater long-term intake and increased consumption of whole fruits may reduce the risk of developing hypertension. PMID:26644239

The use of hormonal implants has gained positive traction in family planning programs in recent times. Compared to other popular methods, such as long-term reversible intrauterine devices, the use of hormonal implants as a family planning method has distinct advantages in terms of long-term efficiency and better user compliance and availability. This paper presents a study protocol to document and evaluate the efficacy, safety, and acceptability of Femplant (contraceptive implant) in Pakistan during the first year of its use among married women of reproductive age (18-44 years) at clinics in two provinces of Pakistan (Sindh and Punjab). A total of 724 married women were enrolled in a noncomparative prospective observational study. The study involved six government clinics from the Population Welfare Department in Sindh Province and 13 clinics run by the Marie Stopes Society (a local nongovernmental organization) in both provinces. The participation of women was subject to voluntary acceptance and medical eligibility. All respondents were interviewed at baseline and subsequently at each scheduled visit during the study period. Side effects, complications and adverse events, if any, were recorded for every participant at each visit to the facility. Over the next 5-year period (2013-2018), 27 million hormonal implants will be made available in lower- to middle-income countries by international donors and agencies. The evidence generated from this study will identify factors affecting the acceptability and satisfaction of end users with Femplant (Sino-implant II). This will help to guide policies to enhance access to and the use of long-acting contraceptive implants in Pakistan and similar developing countries.

Studies evaluating the effect of levetiracetam (LEV) on haematological parameters in patients with epilepsy are very limited. Clinical trials have also reported an unexplained increased incidence of pharyngitis and rhinitis in LEV-treated patients. The objective of this study was to evaluate prospectively the changes in haematological parameters in children treated with LEV monotherapy. White blood cell, neutrophils, lymphocytes, monocytes, haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and platelets were measured in 22 children (13 females, mean age 6.70±4.23 years) with epilepsy, before and after 2 and 6 months of LEV monotherapy. Lymphocyte count was significantly decreased at 6 months (p=0.019) of treatment and this effect was not dose dependent. One child (4.5%) at 2 months and four children (18%) at 6 months of treatment had lymphocyte count below 10th percentile for age. There were no significant alterations in the other parameters evaluated during the study. LEV monotherapy may significantly decrease lymphocyte count at six months of treatment in children with epilepsy. Further prospective studies are needed to investigate the effect of LEV on haematological parameters and the possible association with the higher incidence of infections reported in children receiving LEV.

Treatment for boys with haemophilia in China is rapidly improving; however, comprehensive outcomes have not been examined prospectively. The aim of this study was to evaluate the effect of short-term full-dose prophylaxis compared to on-demand treatment, on the Health-Related Quality of Life (HR-QoL) of boys with severe haemophilia A (HA) in China. Boys with severe HA (FVIII<1%) completed 3 months of on-demand treatment and 3 months of full-dose prophylaxis (25 FVIII IU per kg 3x per week). The primary outcomes were child- and parent-reported Canadian Hemophilia Outcomes - Kids Life Assessment Tool (CHO-KLAT) scores. The number and type of bleeds and Activities Scale for Kids (ASK) scores were also recorded. Analyses included 23 boys between 4 and 15.9 years of age. The number of bleeds decreased by 94% on prophylaxis (P < 0.0001, Wilcoxon Signed-Rank test). The mean child-reported CHO-KLAT scores for boys ≥7 years (n = 20) was 61.4 (±10.9) during on-demand treatment and 61.9 (±11.4) following short-term prophylaxis (P = 0.72, paired t-test). The mean parent-reported CHO-KLAT score during the on-demand phase was 54.4 (±10.5) with an increase of 3.8 points (±8.1; P = 0.04, paired t-test) following prophylaxis. Child-reported CHO-KLAT scores were lower in boys with severe HA in China than reported in countries with access to full-dose prophylaxis. Boys reported higher HR-QoL scores than their parents. Small improvements in ASK scores were noted following the prophylaxis phase. These changes were only significant in the parent-reported CHO-KLAT scores. Longer term prospective clinical trials are needed in China to determine the impact of prophylaxis on HR-QoL in boys with severe HA. © 2017 John Wiley & Sons Ltd.

Long-term cardiovascular complications in metabolic syndrome are a major cause of mortality and morbidity in India and forecasted estimates in this domain of research are scarcely reported in the literature. The aim of present investigation is to estimate the cardiovascular events associated with a representative Indian population of patients suffering from metabolic syndrome using United Kingdom Prospective Diabetes Study risk engine. Patient level data was collated from 567 patients suffering from metabolic syndrome through structured interviews and physician records regarding the input variables, which were entered into the United Kingdom Prospective Diabetes Study risk engine. The patients of metabolic syndrome were selected according to guidelines of National Cholesterol Education Program - Adult Treatment Panel III, modified National Cholesterol Education Program - Adult Treatment Panel III and International Diabetes Federation criteria. A projection for 10 simulated years was run on the engine and output was determined. The data for each patient was processed using the United Kingdom Prospective Diabetes Study risk engine to calculate an estimate of the forecasted value for the cardiovascular complications after a period of 10 years. The absolute risk (95% confidence interval) for coronary heart disease, fatal coronary heart disease, stroke and fatal stroke for 10 years was 3.79 (1.5-3.2), 9.6 (6.8-10.7), 7.91 (6.5-9.9) and 3.57 (2.3-4.5), respectively. The relative risk (95% confidence interval) for coronary heart disease, fatal coronary heart disease, stroke and fatal stroke was 17.8 (12.98-19.99), 7 (6.7-7.2), 5.9 (4.0-6.6) and 4.7 (3.2-5.7), respectively. Simulated projections of metabolic syndrome patients predict serious life-threatening cardiovascular consequences in the representative cohort of patients in western India.

The objective of this prospective, open-label study was to determine the long-term effect of medicinal cannabis treatment on pain and functional outcomes in participants with treatment-resistant chronic pain. The primary outcome was the change in the pain symptom score on the S-TOPS (Treatment Outcomes in Pain Survey-Short Form) questionnaire at the 6-month follow-up in an intent-to-treat population. Secondary outcomes included the change in S-TOPS physical, social, and emotional disability scales, the pain severity, and pain interference on the Brief Pain Inventory, sleep problems, and the change in opioid consumption. A total of 274 participants were approved for treatment; complete baseline data were available for 206 (intent-to-treat), and complete follow-up data for 176 participants. At follow-up, the pain symptom score improved from median 83.3 (95% confidence interval [CI], 79.2-87.5) to 75.0 (95% CI, 70.8-79.2) (P<0.001). The pain severity score (7.50 [95% CI, 6.75-7.75] to 6.25 [95% CI, 5.75-6.75]) and the pain interference score (8.14 [95% CI, 7.28-8.43] to 6.71 [95% CI, 6.14-7.14]) improved (both P<0.001), together with most social and emotional disability scores. Opioid consumption at follow-up decreased by 44% (P<0.001). Serious adverse effects led to treatment discontinuation in 2 participants. The treatment of chronic pain with medicinal cannabis in this open-label, prospective cohort resulted in improved pain and functional outcomes, and a significant reduction in opioid use. Results suggest long-term benefit of cannabis treatment in this group of patients, but the study's noncontrolled nature should be considered when extrapolating the results.

Objective Despite modern anti-epileptic drug treatment, approximately 30% of epilepsies remain medically refractory and for these patients, epilepsy surgery may be a treatment option. There have been numerous studies demonstrating good outcome of epilepsy surgery in the short to median term however, there are a limited number of studies looking at the long-term outcomes. The aim of this study was to ascertain the long-term outcome of resective epilepsy surgery in a large neurosurgery hospital in the U.K. Methods This a retrospective analysis of prospectively collected data. We used the 2001 International League Against Epilepsy (ILAE) classification system to classify seizure freedom and Kaplan-Meier survival analysis to estimate the probability of seizure freedom. Results We included 284 patients who underwent epilepsy surgery (178 anterior temporal lobe resections, 37 selective amygdalohippocampectomies, 33 temporal lesionectomies, 36 extratemporal lesionectomies), and had a prospective median follow-up of 5 years (range 1–27). Kaplan-Meier estimates showed that 47% (95% CI 40–58) remained seizure free (apart from simple partial seizures) at 5 years and 38% (95% CI 31–45) at 10 years after surgery. 74% (95% CI 69–80) had a greater than 50% seizure reduction at 5 years and 70% (95% CI 64–77) at 10 years. Patients who had an amygdalohippocampectomy were more likely to have seizure recurrence than patients who had an anterior temporal lobe resection (p = 0.006) and temporal lesionectomy (p = 0.029). There was no significant difference between extra temporal and temporal lesionectomies. Hippocampal sclerosis was associated with a good outcome but declined in relative frequency over the years. Conclusion The vast majority of patients who were not seizure free experienced at least a substantial and long-lasting reduction in seizure frequency. A positive long-term outcome after epilepsy surgery is possible for many patients and especially those with hippocampal sclerosis or those who had anterior temporal lobe resections. PMID:29768433

There are few long-term follow-up studies of parasuicides incorporating face-to-face interviews. To date no study has evaluated the prevalence of psychiatric morbidity at long-term follow-up of parasuicides using diagnostic rating scales, nor has any study examined parental bonding issues in this population. We attempted a prospective follow-up of 85 parasuicide cases an average of 8 1/2 years later. Psychiatric morbidity, social functioning, and recollections of the parenting style of their parents were assessed using the Clinical Interview Schedule, the Social Maladjustment Scale, and the Parental Bonding Instrument, respectively. Thirty-nine persons in total were interviewed, 19 of whom were well and 20 of whom had psychiatric morbidity. Five and died during the follow-up period, 3 by suicide. Migration, refusals, and untraceability were common. Parasuicide was associated with parental overprotection during childhood. Long-term outcome is poor, especially among those who engaged in repeated parasuicides.

Objective The objective was to assess the long-term safety profile of dual-release hydrocortisone (DR-HC) in patients with adrenal insufficiency (AI). Design Randomised, open-label, crossover trial of DR-HC or thrice-daily hydrocortisone for 3 months each (stage 1) followed by two consecutive, prospective, open-label studies of DR-HC for 6 months (stage 2) and 18 months (stage 3) at five university clinics in Sweden. Methods Sixty-four adults with primary AI started stage 1, and an additional 16 entered stage 3. Patients received DR-HC 20–40 mg once daily and hydrocortisone 20–40 mg divided into three daily doses (stage 1 only). Main outcome measures were adverse events (AEs) and intercurrent illness (self-reported hydrocortisone use during illness). Results In stage 1, patients had a median 1.5 (range, 1–9) intercurrent illness events with DR-HC and 1.0 (1–8) with thrice-daily hydrocortisone. AEs during stage 1 were not related to the cortisol exposure-time profile. The percentage of patients with one or more AEs during stage 1 (73.4% with DR-HC; 65.6% with thrice-daily hydrocortisone) decreased during stage 2, when all patients received DR-HC (51% in the first 3 months; 54% in the second 3 months). In stages 1–3 combined, 19 patients experienced 27 serious AEs, equating to 18.6 serious AEs/100 patient-years of DR-HC exposure. Conclusions This long-term prospective trial is the first to document the safety of DR-HC in patients with primary AI and demonstrates that such treatment is well tolerated during 24 consecutive months of therapy.

To determine the prospective association between retrospectively assessed physical work environment during working life and prospectively assessed sickness absence and labour market exit among older workers. Using Cox regression analyses we estimated the 4-year to 6-year prospective risk of register-based long-term sickness absence (LTSA), disability pension, early retirement and unemployment from exposure to different physical work environmental factors during working life among 5076 older workers (age 49-63 at baseline) from the Copenhagen Aging and Midlife Biobank cohort. Very hard physical work throughout working life was a risk factor for LTSA (HR 1.66,95% CI 1.32 to 2.07), disability pension (HR 2.21,95% CI 1.04 to 4.72) and early retirement (HR 1.57,95% CI 1.13 to 2.17). Both short-term (<10 years) and long-term (≥20 years) exposures to lifting or carrying of heavy burdens predicted the risk of LTSA (HRs 1.49-1.56) and disability pension (HRs 2.26-3.29). In contrast, exposure to dust was associated with LTSA and disability pension only following 20 or more exposure years. Retrospectively assessed hard physical work during working life and exposure to several factors in the physical work environment, especially heavy lifting, were important for labour market exit and sickness absence. This study underscores the importance of reducing physical work exposures throughout the working life course for preventing sickness absence and premature exit from the labour market. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Customization of the tracheoesophageal (TE) voice prosthesis (VP) is often preferred over surgical closure to prevent aspiration around the VP in laryngectomized patients with an enlarged tracheoesophageal puncture (TEP), but it has not been thoroughly evaluated. Single-institution prospective trial. A prospective trial was conducted to evaluate the effectiveness of a customized VP with the addition of an enlarged tracheal and/or esophageal collar in patients with leakage around an enlarged TEP. Absence of leakage around the VP after placement defined immediate effectiveness. Long-term success was defined by the prevention of adverse events related to leakage during the study period. Events that defined failure included: permanent gastrostomy dependence, aspiration pneumonia, and/or surgical TEP closure. Twenty-one patients with enlarged TEP were enrolled (2003-2006). Insertion of a customized VP was unsuccessful in one patient; 145 customizations were performed in the remaining 20 patients (median, 3.5 customizations) during the trial period. Of the customizations, 77% (112/145) prevented leakage immediately after VP insertion. The most common adverse event was dislodgement of the prosthesis (11%) or the collar alone (7%) in 18% (26/145) of customized VP placements. Six patients who died of disease were not evaluable for long-term outcomes. Long-term success was achieved in 80% (12/15) of evaluable patients who avoided permanent gastrostomy, aspiration pneumonia, and surgical TEP closure. Prosthetic customization offers an effective method to prevent leakage around the VP in many patients with an enlarged TEP, thereby preserving TE voice while avoiding surgical closure in this high-risk population.

As electronic health records and computerized workflows expand, there are unprecedented opportunities to digitally connect with patients using secure portals. To realize the value of patient portals, initial reach across populations will need to be demonstrated, as well as sustained usage over time. The study aim was to identify patient factors associated with short-term and long-term portal usage after patients registered to access all portal functions. We prospectively followed a cohort of patients at a large Department of Veterans Affairs (VA) health care facility who recently completed identity proofing to use the VA patient portal. Information collected at baseline encompassed patient factors potentially associated with portal usage, including: demographics, Internet access and use, health literacy, patient activation, and self-reported health conditions. The primary outcome was the frequency of portal log-ins during 6-month and 18-month time intervals after study enrollment. A total of 270 study participants were followed prospectively. Almost all participants (260/268, 97.0%) reported going online, typically at home (248/268, 92.5%). At 6 months, 84.1% (227/270) of participants had visited the portal, with some variation in usage across demographic and health-related subgroups. There were no significant differences in portal log-ins by age, gender, education, marital status, race/ethnicity, distance to a VA facility, or patient activation measure. Significantly higher portal usage was seen among participants using high-speed broadband at home, greater self-reported ability using the Internet, and routinely going online. By 18 months, 91% participants had logged in to the portal, and no significant associations were found between usage and demographics, health status, or patient activation. When examining portal activity between 6 and 18 months, patients who were infrequent or high portal users remained in those categories, respectively. Short-term and long-term portal usage was associated with having broadband at home, high self-rated ability when using the Internet, and overall online behavior. Digital inclusion, or ready access to the Internet and digital skills, appears to be a social determinant in patient exposure to portal services. ©Susan S Woods, Christopher W Forsberg, Erin C Schwartz, Kim M Nazi, Judith H Hibbard, Thomas K Houston, Martha Gerrity.

Recanalization of long segmental occlusions of femoropopliteal arteries can be achieved by angioplasty and implantation of nitinol stents with high procedural success rates. However, due to recurrent in-stent restenoses (ISR) some patients need repeated interventions and their intermediate success rates are uncertain. Patients who were treated in our center from March 2008 through February 2011 due to symptomatic ISR (as determined by Duplex sonography) were retrospectively included in the study. After endovascular treatment of their ISR, they were prospectively evaluated with regard to recurrent ISR of the target lesions. A total of 36 limbs (=lesions) in 32 patients (69% male, mean age 69±9 years) were successfully treated by balloon-angioplasty. Adjunctive cutting balloons and drug eluting balloons were used in 78% and 8%, respectively. Mean follow-up was 326 days. Recurrent ISR occurred in 10 (28%) lesions, while 26 (78%) lesions showed no recurrence of ISR. In a multivariate logistic regression analysis, age, gender, cardiovascular risk factors, renal failure and medication with cilostazol were not significantly associated with recurrent ISR. Moreover, the number of previous interventions of the target lesions was not an independent predictor of recurrent ISR. Patients with multiple recurrences of ISR seem to have the same prospects of acute and mid-term success for endovascular treatment as those with first presentation of ISR. However, this observation has to be confirmed by prospective, large scale studies with a longer follow-up period to determine the significance of endovascular intervention within the scope of different revascularization approaches for treatment of recurrent ISR.

Sleep duration and cardiometabolic risk: a review of the epidemiologic evidence.

PubMed

Knutson, Kristen L

2010-10-01

Laboratory studies have found that short-term sleep restriction is associated with impairments in glucose metabolism, appetite regulation and blood pressure regulation. This chapter reviews the epidemiologic evidence for an association between habitual sleep duration and quality and risk of cardiometabolic diseases including obesity, diabetes and hypertension. Multiple studies observed a cross-sectional association between short sleep duration (generally <6 h per night) and increased body mass index or obesity, prevalent diabetes and prevalent hypertension. Many studies also reported an association between self-reported long sleep duration (generally >8 h per night) and cardiometabolic disease. There have been a few prospective studies and several, but not all, have found an association between short sleep and incident diabetes, hypertension and markers of cardiovascular disease. Future prospective epidemiologic studies need to include objective measures of sleep, and intervention studies are needed in order to establish a causal link between impaired or insufficient sleep and cardiometabolic disease risk.

Retaining subjects from disadvantaged populations in long-term studies is necessary to obtain high-quality data. This article presents cumulative retention rates from a 5-year prospective cohort study, the Pediatric Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection study. It also presents results of a cross-sectional qualitative survey about factors that induced caregivers to stay in the study. Although the repeated study visits were long and uncomfortable, cumulative retention among the 298 HIV-infected children was 80%. Incentives considered important by the caregivers included phone contact with nurse coordinators, nurse coordinators accompanying the caregiver and child during visits, phone reminders for appointments, help with scheduling, meals and transportation, access to health care, and relationships with staff. Thus, the high follow-up rate was in part due to nurses’ efforts to reduce the study’s burden on the families, provide tangible and intangible incentives, and establish personal relationships with families.

Background Recovery from a massive burn is characterized by catabolic and hypermetabolic responses that persist up to 2 years and impair rehabilitation and reintegration. The objective of this study was to determine the effects of long-term treatment with recombinant human growth hormone (rhGH) on growth, hypermetabolism, body composition, bone metabolism, cardiac work, and scarring in a large prospective randomized single-center controlled clinical trial in pediatric patients with massive burns. Patients and Methods A total of 205 pediatric patients with massive burns over 40% total body surface area were prospectively enrolled between 1998 and 2007 (clinicaltrials.gov ID NCT00675714). Patients were randomized to receive either placebo (n = 94) or long-term rhGH at 0.05, 0.1, or 0.2 mg/kg/d (n = 101). Changes in weight, body composition, bone metabolism, cardiac output, resting energy expenditure, hormones, and scar development were measured at patient discharge and at 6, 9, 12, 18, and 24 months postburn. Statistical analysis used Tukey t test or ANOVA followed by Bonferroni correction. Significance was accepted at P < 0.05. Results RhGH administration markedly improved growth and lean body mass, whereas hypermetabolism was significantly attenuated. Serum growth hormone, insulin-like growth factor-I, and IGFBP-3 was significantly increased, whereas percent body fat content significantly decreased when compared with placebo, P < 0.05. A subset analysis revealed most lean body mass gain in the 0.2 mg/kg group, P < 0.05. Bone mineral content showed an unexpected decrease in the 0.2 mg/kg group, along with a decrease in PTH and increase in osteocalcin levels, P < 0.05. Resting energy expenditure improved with rhGH administration, most markedly in the 0.1 mg/kg/d rhGH group, P < 0.05. Cardiac output was decreased at 12 and 18 months postburn in the rhGH group. Long-term administration of 0.1 and 0.2 mg/kg/d rhGH significantly improved scarring at 12 months postburn, P < 0.05. Conclusion This large prospective clinical trial showed that long-term treatment with rhGH effectively enhances recovery of severely burned pediatric patients. PMID:19734776

The primary aim of this pilot study was to prospectively assess a flowchart to screen and diagnose paced patients (pts) affected by sleep apnoeas, by crosschecking indexes derived from pacemakers (minute ventilation sensor on-board) with Sleep-Lab Polygraphy (PG) outcomes. Secondarily, "smoothed" long-term pacemaker indexes (all the information between two consecutive follow-up visits) have been retrospectively compared vs. standard short-term pacemaker indexes (last 24h) at each follow-up (FU) visit, to test their correlation and diagnostic concordance. Data from long-term FU of 61 paced pts were collected. At each visit, the standard short-term apnoea+hypopnoea (PM_AHI) index was retrieved from the pacemaker memory. Patients showing PM_AHI ≥ 30 at least once during FU were proposed to undergo a PG for diagnostic confirmation. Smoothed pacemaker (PM_SAHI) indexes were calculated by averaging the overall number of apnoeas/hypopnoeas over the period between two FU visits, and retrospectively compared with standard PM_AHI. Data were available from 609 consecutive visits (overall 4.64 ± 1.78 years FU). PM_AHI indexes were positive during FU in 40/61 pts (65.6%); 26/40 pts (65%) accepted to undergo a PG recording; Sleep-Lab confirmed positivity in 22/26 pts (84.6% positive predictive value for PM_AHI). A strong correlation (r=0.73) and a high level of concordance were found between smoothed and standard indexes (multivariate analysis, Cohen's-k and Z-score tests). Pacemaker-derived indexes may help in screening paced pts potentially affected by sleep apnoeas. Long-term "smoothed" apnoea indexes could improve the accuracy of pacemaker screening capability, even though this hypothesis must be prospectively confirmed by larger studies.

Functional neuroimaging studies of prospective memory: what have we learnt so far?

PubMed

Burgess, Paul W; Gonen-Yaacovi, Gil; Volle, Emmanuelle

2011-07-01

The complexity of the behaviour described by the term "prospective memory" meant that it was not at all clear, when the earliest studies were conducted, that this would prove a fruitful area for neuroimaging study. However, a consistent relation rapidly emerged between activation in rostral prefrontal cortex (approximating Brodmann Area 10) and performance of prospective memory paradigms. This consistency has greatly increased the accumulation of findings, since each study has offered perspectives on the previous ones. Considerable help too has come from broad agreement between functional neuroimaging findings and those from other methods (e.g. human lesion studies, electrophysiology). The result has been a quite startling degree of advance given the relatively few studies that have been conducted. These findings are summarised, along with those from other brain regions, and new directions suggested. Key points are that there is a medial-lateral dissociation within rostral PFC. Some (but not all) regions of medial rostral PFC are typically more active during performance of the ongoing task only, and lateral aspects are relatively more active during conditions involving delayed intentions. Some of these rostral PFC activations seem remarkably insensitive to the form of stimulus material presented, the nature of the ongoing task, the specifics of the intention, how easy or hard the PM cue is to detect, or the intended action is to recall. However there are other regions within rostral PFC where haemodynamic changes vary with alterations in these, and other, aspects of prospective memory paradigms. It is concluded that rostral PFC most likely plays a super-ordinate role during many stages of creating, maintaining and enacting delayed intentions, which in some cases may be linked to recent evidence showing that this brain region is involved in the control of stimulus-oriented vs. stimulus-independent attending. Other key brain regions activated during prospective memory paradigms appear to be the parietal lobe, especially Brodmann Area (BA) 40 and precuneus (BA 7), and the anterior cingulate (BA 32). These regions are often co-activated with lateral rostral PFC across a wide range of tasks, not just those involving prospective memory. Copyright © 2011. Published by Elsevier Ltd.

International travel from low-incidence to high-incidence countries for tuberculosis (TB) is regarded as a risk factor for acquiring TB infection. In this prospective study among long-term travellers we examined the incidence of TB infection using Interferon gamma release assay (IGRA) test and compared these data with results from a visit to the TB department to which all long-term travellers were routinely referred. Immunocompetent adults, travelling for 13-52 weeks to TB-endemic countries, donated blood pre- and post-travel for IGRA. The pre-travel IGRA was only tested in case of a positive IGRA post-travel. Results from their visit(s) to the TB department for TST pre- and post-travel were collected and compared with study results. We found two IGRA conversions in a group of 516 travellers, resulting in an attack rate (AR) of 0.4% (95% CI: 0.5 - 13.9) and an incidence rate (IR) of 0.85 per 1000 person-months (95% CI: 0.1-3.1).We found 5 tuberculin skin test (TST) conversions, resulting in AR of 1.9% (5/261; 95% CI: 0.6 - 4.4) and an IR of 4.26 per 1000 person-months (95% CI: 1.38- 9.94). In our study these converters all had a negative IGRA. One traveller however, who was retested later at the TB department due to a positive TST, then appeared to have seroconverted. The risk of long-term travellers among our study population acquiring TB infection is low. We conclude that post-travel IGRA alone could be used for screening for TB infection among long-term travellers to high-endemic TB countries, but preferably not earlier than 8 weeks after return. One might even argue that IGRA testing should be limited to only those travellers who are going to work in a medical setting. A person with a positive IGRA should be referred to a TB physician for further evaluation.

Detection of medication-related problems in hospital practice: a review

Manias, Elizabeth

2013-01-01

This review examines the effectiveness of detection methods in terms of their ability to identify and accurately determine medication-related problems in hospitals. A search was conducted of databases from inception to June 2012. The following keywords were used in combination: medication error or adverse drug event or adverse drug reaction, comparison, detection, hospital and method. Seven detection methods were considered: chart review, claims data review, computer monitoring, direct care observation, interviews, prospective data collection and incident reporting. Forty relevant studies were located. Detection methods that were better able to identify medication-related problems compared with other methods tested in the same study included chart review, computer monitoring, direct care observation and prospective data collection. However, only small numbers of studies were involved in comparisons with direct care observation (n = 5) and prospective data collection (n = 6). There was little focus on detecting medication-related problems during various stages of the medication process, and comparisons associated with the seriousness of medication-related problems were examined in 19 studies. Only 17 studies involved appropriate comparisons with a gold standard, which provided details about sensitivities and specificities. In view of the relatively low identification of medication-related problems with incident reporting, use of this method in tracking trends over time should be met with some scepticism. Greater attention should be placed on combining methods, such as chart review and computer monitoring in examining trends. More research is needed on the use of claims data, direct care observation, interviews and prospective data collection as detection methods. PMID:23194349

Endoscopic hemoclip application is an effective and safe method of endoscopic hemostasis. We conducted a multicenter retrospective study on hemoclip and hemoclip combination therapy based on prospective cohort database in terms of hemostatic efficacy not in clinical trial but in real clinical practice. Data on endoscopic hemostasis for non-variceal upper gastrointestinal bleeding (NVUGIB) were prospectively collected from February 2011 to December 2013. Among 1,584 patients with NVUGIB, 186 patients treated with hemoclip were enrolled in this study. Subjects were divided into three groups: Group 1 (n = 62), hemoclipping only; group 2 (n = 88), hemoclipping plus epinephrine injection; and group 3 (n = 36), hemocliping and epinephrine injection plus other endoscopic hemostatic modalities. Primary outcomes included rebleeding, other therapeutic management, hospitalization period, fasting period and mortality. Secondary outcomes were bleeding associated mortality and overall mortality. Active bleeding and peptic ulcer bleeding were more common in group 3 than in group 1 and in group 2 (p <œ 0.001). However, primary outcomes (rebleeding, other management, morbidity, hospitalization period, fasting period and mortality) and secondary outcomes (bleeding associated mortality and total mortality) were not different among groups. Combination therapy of epinephrine injection and other modalities with hemoclips did not show advantage over hemoclipping alone in this prospective cohort study. However, there is a tendency to perform combination therapy in active bleeding which resulted in equivalent hemostatic success rate, and this reflects the role of combination therapy in clinical practice.

Bariatric surgery is the most effective treatment option for obesity, and gut hormones are implicated in the reduction of appetite and weight after Roux-en-Y gastric bypass. Although there is increasing interest in the gut hormone changes after gastric bypass, the long-term changes have not been fully elucidated. Thirty-four participants were studied cross-sectionally at four different time points, pre-operatively (n = 17) and 12 (n = 6), 18 (n = 5) and 24 months (n = 6) after laparoscopic Roux-en-Y gastric bypass. Another group of patients (n = 6) were studied prospectively (18-24 months). All participants were given a standard 400 kcal meal after a 12-h fast, and plasma levels of peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) were correlated with changes in appetite over 3 h using visual analogue scores. The post-operative groups at 12, 18 and 24 months had a higher post-prandial PYY response compared to pre-operative (p < 0.05). This finding was confirmed in the prospective study at 18 and 24 months. There was a trend for increasing GLP-1 response at 18 and 24 months, but this did not reach statistical significance (p = 0.189) in the prospective study. Satiety was significantly reduced in the post-operative groups at 12, 18 and 24 months compared to pre-operative levels (p < 0.05). Roux-en-Y gastric bypass causes an enhanced gut hormone response and increased satiety following a meal. This response is sustained over a 24-month period and may partly explain why weight loss is maintained.

Need for recovery from work related fatigue and its role in the development and prediction of subjective health complaints

2003-01-01

Aims: To present the available empirical evidence for the assumed position of the concept of work related fatigue as: (1) short term effect of the working day; and (2) an intermediate variable between work demands and the development of subjective health complaints and sickness absence. Methods: Results from six single occupation studies, conducted between 1996 and 2002, are presented. Work demands (working hours, decision latitude, break control/autonomy, and mental, emotional, and physical demands) were assessed through validated scales. Work related fatigue was represented and assessed by means of the need for recovery after working time scale in all studies. Subjective health complaints and duration of sickness absence were quantified with the same instruments in most studies as well. Both cross sectional studies (four) as well as prospective studies (two; up to two years follow up) were performed. Cross sectional data of 3820 workers, in total, were available. Prospective data were accessible for 1200 workers in industry and health care. Models were tested with stepwise multiple regression analyses. Results: Strong associations between work demands and need for necovery were found in different occupations. The variance explained in need for recovery by work demands, age, and (baseline) need for recovery ranged between 14% and 48% in both types of studies. The amount of explained variance by work demands, age, and (baseline) need for recovery in subjective health complaints ranged between 24% and 58% in the different occupations. The prospective data showed the prognostic value of need for recovery in relation to subjective health complaints (in terms of psychosomatic complaints, emotional exhaustion, or sleep problems) and duration of future sickness absence. Conclusions: The hypothesised role for work related fatigue as a link in the causal string of events, that is assumed to exist between repeated adverse work demands and the development of work related stress reactions, (psychological) overload and, eventually, health problems, was confirmed.

Resolved: There is sufficient scientific evidence that decreasing sugar-sweetened beverage consumption will reduce the prevalence of obesity and obesity-related diseases

PubMed Central

Hu, Frank B.

2017-01-01

Sugar-sweetened beverages (SSBs) are the single largest source of added sugar and the top source of energy intake in the US diet. In this review, we evaluate whether there is sufficient scientific evidence that decreasing SSB consumption will reduce the prevalence of obesity and its related diseases. Since prospective cohort studies address dietary determinants of long-term weight gain and chronic diseases, whereas randomized controlled trials (RCTs) typically evaluate short-term effects of specific interventions on weight change, both types of evidence are critical in evaluating causality. Findings from well-powered prospective cohorts have consistently shown a significant association, established temporality, and demonstrated a direct dose-response relationship between SSB consumption and long-term weight gain and risk of type 2 diabetes (T2D). A recently published meta-analysis of RCTs commissioned by the World Health Organization (WHO) found that decreased intake of added sugars significantly reduced body weight (0.80 kg, 95% CI 0.39 to 1.21; P<0.001), whereas increased sugar intake led to a comparable weight increase (0.75 kg, 0.30 to 1.19; P=0.001). A parallel meta-analysis of cohort studies also found that higher intake of SSBs among children was associated with 55% (95% CI 32%-82%) higher risk of being overweight or obese compared to those with lower intake. Another meta-analysis of eight prospective cohort studies found that 1–2 servings/day of SSB intake was associated with a 26% (95% CI 12–41%) greater risk of developing T2D compared to occasional intake (< 1 serving/month). Recently, two large RCTs with a high degree of compliance provided convincing data that reducing consumption of SSBs significantly decreases weight gain and adiposity in children and adolescents. Taken together, the evidence that decreasing SSBs will decrease the risk of obesity and related diseases such as T2D is compelling. Several additional issues warrant further discussion. First, prevention of long-term weight gain through dietary changes such as limiting consumption of SSBs is more important than short-term weight loss in reducing the prevalence of obesity in the population. This is because once an individual becomes obese, it is difficult to lose weight and keep it off. Second, we should consider the totality of evidence rather than selective pieces of evidence (e.g., from short-term RCTs only). Finally, while recognizing that the evidence of harm on health against SSBs is strong, we should avoid the trap of waiting for absolute proof before allowing public health action to be taken.

2010-01-01

This study examined whether intervention-induced changes in mother-child relationship quality and discipline led to short-term (6 months) and long-term (6 years) changes in children's coping processes in a sample of 240 youth aged 9-12 years when assessed initially. Data were from a randomized, experimental trial of a parenting-focused preventive intervention designed to improve children's post-divorce adjustment. Three-wave prospective mediational analyses revealed that intervention-induced improvements in relationship quality led to increases in coping efficacy at 6 months and to increases in coping efficacy and active coping at 6 years. Tests of the mediated effects were significant for all 3 indirect paths. Results are discussed in terms of pathways to adaptive coping and implications for the implementation of preventive interventions targeting coping. PMID:21291440

Ketamine is an emerging drug for the treatment of acute undifferentiated agitation in the prehospital environment, however no prospective comparative studies have evaluated its effectiveness or safety in this clinical setting. We hypothesized 5 mg/kg of intramuscular ketamine would be superior to 10 mg of intramuscular haloperidol for severe prehospital agitation, with time to adequate sedation as the primary outcome measure. This was a prospective open label study of all patients in an urban EMS system requiring chemical sedation for severe acute undifferentiated agitation that were subsequently transported to the EMS system's primary Emergency Department. All paramedics were trained in the Altered Mental Status Scale and prospectively recorded agitation scores on all patients. Two 6-month periods where either ketamine or haloperidol was the first-line therapy for severe agitation were prospectively compared primarily for time to adequate sedation. Secondary outcomes included laboratory data and adverse medication events. 146 subjects were enrolled; 64 received ketamine, 82 received haloperidol. Median time to adequate sedation for the ketamine group was 5 minutes (range 0.4-23) vs. 17 minutes (range 2-84) in the haloperidol group (difference 12 minutes, 95% CI 9-15). Complications occurred in 49% (27/55) of patients receiving ketamine vs. 5% (4/82) in the haloperidol group. Complications specific to the ketamine group included hypersalivation (21/56, 38%), emergence reaction (5/52, 10%), vomiting (5/57, 9%), and laryngospasm (3/55, 5%). Intubation was also significantly higher in the ketamine group; 39% of patients receiving ketamine were intubated vs. 4% of patients receiving haloperidol. Ketamine is superior to haloperidol in terms of time to adequate sedation for severe prehospital acute undifferentiated agitation, but is associated with more complications and a higher intubation rate.

Our aim was to evaluate the efficacy of our treatment program for children with lower urinary tract conditions, developed at the Department of Pediatric Nephrology of the University Children's Hospital in Ljubljana. Sixty-four patients with lower urinary tract conditions were randomly allocated to two groups. Group A received treatment immediately, whereas patients of group B received no treatment for a period of 3 months-the amount of time it takes to complete our program. No child in group B experienced spontaneous regression of their symptoms in the 3-month delay period, while the patients of group A were already being treated and were achieving results. Thus, all the patients of group B then entered the program in exactly the same way as patients of group A. The final success rate in both groups did not differ significantly (p = 0.706-1.000) and ranged from 86.2 % for group A and 86.7 to 90 % for group B. Long-term follow-up showed statistically identical success rates (p = 1.000). This prospective controlled study with long-term follow-up (48 months) shows that our treatment program, applied as an inpatient voiding school program, is an effective method, with durable results.

Schizophrenia is associated with impairment in prospective memory, the ability to remember to carry out an intended action in the future. It has been established that cue identification (detection of the cue event signaling that an intended action should be performed) and intention retrieval (retrieval of an intention from long-term memory following the recognition of a prospective cue) are two important processes underlying prospective memory. The purpose of this study was to examine prospective memory deficit and underlying cognitive processes in patients with first-episode schizophrenia. This study examined cue identification and intention retrieval components of event-based prospective memory using a dual-task paradigm in 30 patients with first-episode schizophrenia and 30 healthy controls. All participants were also administered a set of tests assessing working memory and retrospective memory. Both cue identification and intention retrieval were impaired in patients with first-episode schizophrenia compared with healthy controls ( ps < 0.05), with a large effect size for cue identification (Cohen's d = 0.98) and a medium effect size for intention retrieval (Cohen's d = 0.62). After controlling for working memory and retrospective memory, the difference in cue identification between patients and healthy controls remained significant. However, the difference in intention retrieval between the two groups was no longer significant. In addition, there was a significant inverse relationship between cue identification and negative symptoms ( r = -0.446, p = 0.013) in the patient group. These findings suggest that both cue identification and intention retrieval in event-based prospective memory are impaired in patients with first-episode schizophrenia. Cue identification and intention retrieval could be potentially used as biomarkers for early detection and treatment prognosis of schizophrenia. In addition, addressing cue identification deficit through cognitive enhancement training may potentially improve negative symptoms as well.

Long-term treatment with appropriate doses of carvedilol or metoprolol is currently recommended for patients with heart failure with reduced ejection fraction (HFrEF) to decrease the risk of death, hospitalizations, and patients' symptoms. It remains unclear if the β blockers used in patients with HFrEF are equal or carvedilol is superior to metoprolol types. We performed a meta-analysis of the comparative effects of carvedilol versus metoprolol tartrate and succinate on all-cause mortality and/or hospitalization. We conducted an Embase and MEDLINE search for prospective controlled trials and cohort studies of patients with HFrEF who were received to treatment with carvedilol versus metoprolol. We identified 4 prospective controlled and 6 cohort studies with 30,943 patients who received carvedilol and 69,925 patients on metoprolol types (tartrate and succinate) with an average follow-up duration of 36.4 months. All-cause mortality was reduced in prospective studies with carvedilol versus metoprolol tartrate. Neither all-cause mortality nor hospitalizations were significantly different between carvedilol and metoprolol succinate in the cohort studies. In conclusion, in patients with HFrEF, carvedilol and metoprolol succinate have similar effects in reducing all-cause mortality. Copyright © 2015 Elsevier Inc. All rights reserved.

The present study used a collaborative framework to integrate two long-term prospective studies: the Terman Life Cycle Study and the Hawaii Personality and Health Longitudinal Study. Using a five-factor personality-trait framework, teacher assessments of child personality were rationally and empirically aligned to establish similar factor structures across samples. Comparable items related to adult self-rated health, education, and alcohol use were harmonized, and data were pooled on harmonized items. A structural model was estimated, allowing paths to differ by sample. Harmonized child personality factors were then used to examine markers of physiological dysfunction in the Hawaii sample and mortality risk in the Terman sample. Harmonized conscientiousness predicted less physiological dysfunction in the Hawaii sample and lower mortality risk in the Terman sample. These results illustrate how collaborative, integrative work with multiple samples offers the exciting possibility that samples from different cohorts and ages can be linked together to directly test lifespan theories of personality and health.

The aim of the present study is to prospectively evaluate the prognostic value of previously defined [(18)F]2-fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) criteria of early metabolic response in patients with locally advanced rectal cancer (LARC) after long-term follow-up. Forty-two patients with poor prognosis LARC underwent three biweekly courses of chemotherapy with oxaliplatin, raltitrexed and 5-fluorouracil modulated by levofolinic acid during pelvic radiotherapy. FDG PET studies were performed before and 12 days after the beginning of the chemoradiotherapy (CRT) treatment. Total mesorectal excision (TME) was carried out 8 weeks after completion of CRT. A previously identified cutoff value of ≥52 % reduction of the baseline mean FDG standardized uptake value (SUV(mean)) was applied to differentiate metabolic responders from non-responders and correlated to tumour regression grade (TRG) and survival. Twenty-two metabolic responders showed complete (TRG1) or subtotal tumour regression (TRG2) and demonstrated a statistically significantly higher 5-year relapse-free survival (RFS) compared with the 20 non-responders (86 vs 55 %, p = .014) who showed TRG3 and TRG4 pathologic responses. A multivariate analysis demonstrated that early ∆SUV(mean) was the only pre-surgical parameter correlated to the likelihood of recurrence (p = .05). This study is the first prospective long-term evaluation demonstrating that FDG PET is not only an early predictor of pathologic response but is also a valuable prognostic tool. Our results indicate the potential of FDG PET for optimizing multidisciplinary management of patients with LARC.

Preterm and former preterm children frequently require sedation/anesthesia for diagnostic and therapeutic procedures. Our objective was to determine the age at which children who are born <37 weeks gestational age are no longer at increased risk for sedation/anesthesia adverse events. Our secondary objective was to describe the nature and incidence of adverse events. This is a prospective observational study of children receiving sedation/anesthesia for diagnostic and/or therapeutic procedures outside of the operating room by the Pediatric Sedation Research Consortium. A total of 57,227 patients 0 to 22 years of age were eligible for this study. All adverse events and descriptive terms were predefined. Logistic regression and locally weighted scatterplot regression were used for analysis. Preterm and former preterm children had higher adverse event rates (14.7% vs 8.5%) compared with children born at term. Our analysis revealed a biphasic pattern for the development of adverse sedation/anesthesia events. Airway and respiratory adverse events were most commonly reported. MRI scans were the most commonly performed procedures in both categories of patients. Patients born preterm are nearly twice as likely to develop sedation/anesthesia adverse events, and this risk continues up to 23 years of age. We recommend obtaining birth history during the formulation of an anesthetic/sedation plan, with heightened awareness that preterm and former preterm children may be at increased risk. Further prospective studies focusing on the etiology and prevention of adverse events in former preterm patients are warranted. Copyright © 2016 by the American Academy of Pediatrics.

The aim of this prospective study was to assess the esthetic outcome and alterations of peri-implant soft tissue using tissue-level implants. Furthermore, the influencing factors, including grafting and gingival biotype, of esthetic outcome of peri-implant soft tissue were also evaluated. Of 38 patients with single missing anterior tooth in maxilla were treated with a Straumann (®) Standard Plus SLA implant. Bone augmentation was performed in 24 patients. Follow-up was conducted at 12 and 24 months after definitive crowns placement. Esthetic outcome using the pink esthetic score/white esthetic score (PES/WES) and clinical parameters were evaluated. The mean PES/WES value at baseline, 1-year, and 2-year examination was 13.79, 14.87, and 14.96. Significant improvement was found between baseline and 1-year examination (P < 0.01). And the improvement between 1-year and 2-year examination was not significant (P = 0.40). The mean PES changing value in patients with thick biotype was significantly higher than those with thin biotype at 2-year after definitive crowns placement (P = 0.03). Graft procedure had an unfavorable effect on mean PES value both at baseline and at follow-up (P < 0.01). No implants were lost at 2-year examination. Three patients experienced peri-implant infection. No significant difference was found with the passage of time in modified plaque index (mPI), probing pocket depth (PPD), and modified bleeding index (mBI). According to the present prospective clinical study, it can be concluded that it is feasible to use tissue-level implant to support single crowns in esthetic area. Favorable short-term esthetic outcome and stability of soft tissue around single implant crowns can be expected in patients with or without graft. However, graft procedures might have an unfavorable effect on the esthetic outcome. Gingival biotype can be considered as prognostic factor for esthetic outcome. RCTs with long-term follow-up are needed to provide evidence for the long-term stability of peri-implant soft tissue using tissue-level implant systems. © 2014 John Wiley & Sons A/S.

A delta-shaped anastomosis in totally laparoscopic Billroth I gastrectomy could be performed easily and sufficiently using only laparoscopic linear staplers. However, the restricted maneuverability and severe blurring of these staplers along with their limited hemostability induced strain. In this study, we determined the feasibility and safety of performing delta-shaped anastomosis using the Endo GIA™ Reloads with Tri-Staple™ Technology combined with Endo GIA™ Ultra Universal stapler (Tri-Staple) with a particular focus on short-term surgical outcomes. We performed a single-institutional prospective interventional study (UMIN 000008014). The Tri-Staple was prospectively used on 23 consecutive patients who underwent a curative totally laparoscopic Billroth I gastrectomy with delta-shaped anastomosis. These patients were matched with the 19 patients previously treated using the ENDOPATH(®) ETS Articulating Linear Cutters (ETS) on clinical and demographic characteristics. There were no differences between the groups in anastomosis-related local complications, morbidity, non-anastomosis-related local complications, total systemic complications, and short-term outcomes with the exception of significantly reduced blood loss in the Tri-Staple group (ETS vs. Tri-Staple: 37 [10-306] vs. 15 [5-210] mL, p = 0.02). Intraoperative bleeding from the staple line was significantly reduced in the Tri-Staple group. The postoperative drain indwelling period (ETS vs. Tri-Staple, 6 [4-10] vs. 4 [2-43] days, p = 0.032), fasting period (5 [3-7] vs. 3 [3-24] days, p = 0.022), and hospital stay (14 [10-47] vs. 11 [6-58] days, p = 0.025) were significantly shorter in the Tri-Staple group. There was no mortality in this series. Acceleration assessed as indices of blurring of stapler tip might have a significant adverse influence on staple-line bleeding at stapling sites. Totally laparoscopic Billroth I distal gastrectomy using Tri-Staple was feasible and safe with favorable short-term surgical outcomes. Reduced blurring while stapling may be a novel endpoint which newly developed stapling devices should target.

Ultrasonic thermometry sensors (UTS) have been intensively studied in the past to measure temperatures from 2080 K to 3380 K. This sensor, which uses the temperature dependence of the acoustic velocity in materials, was developed for experiments in extreme environments. Its major advantages, which are (a) capability of measuring a temperature profile from multiple sensors on a single probe and (b) measurement near the sensor material melting point, can be of great interest when dealing with on-line monitoring of high-temperature safety tests. Ultrasonic techniques were successfully applied in several severe accident related experiments. With new developments of alternative materials, this instrument may be used in a wide range of experimental areas where robustness and compactness are required. Long-term irradiation experiments of nuclear fuel to extremely high burn-ups could benefit from this previous experience. After an overview of UTS technology, this article summarizes experimental work performed to improve the reliability of these sensors. The various designs, advantages, and drawbacks are outlined and future prospects for long-term high-temperature irradiation experiments are discussed.

Long-term effect of coffee consumption on autosomal dominant polycystic kidneys disease progression: results from the Suisse ADPKD, a Prospective Longitudinal Cohort Study.

Previous in vitro experiments of human polycystic kidney disease (PKD) cells reported that caffeine is a risk factor for the promotion of cyst enlargement in patients with autosomal dominant PKD (ADPKD). The relentless progression of ADPKD inclines the majority of physicians to advocate minimization of caffeine consumption despite the absence of clinical data supporting such a recommendation so far. This is the first clinical study to assess prospectively the association between coffee consumption and disease progression in a longitudinal ADPKD cohort. Information on coffee consumption and disease progression was collected at each follow-up visit using standardized measurement methods. The main model for the outcomes, kidney size (height-adjusted total kidney volume, htTKV) and kidney function (estimated glomerular filtration rate, eGFR), was a linear mixed model. Patients entered the on-going Swiss ADPKD study between 2006 and June 2014 and had at least 1 visit every year. The sample size of the study population was 151 with a median follow-up of 4 visits per patient and a median follow-up time of 4.38 years. After multivariate adjustment for age, smoking, hypertension, sex, body mass index and an interaction term (coffee*visit), coffee drinkers did not have a statistically significantly different kidney size compared to non-coffee drinkers (difference of -33.03 cm 3 height adjusted TKV, 95% confidence interval (CI) from -72.41 to 6.34, p = 0.10). After the same adjustment, there was no statistically significant difference in eGFR between coffee and non-coffee drinkers (2.03 ml/min/1.73 m 2 , 95% CI from -0.31 to 4.31, p = 0.089). Data derived from our prospective longitudinal study do not confirm that drinking coffee is a risk factor for ADPKD progression.

To obtain the proof of concept of a novel therapy for Alzheimer's disease (AD), we conducted two prospective studies with hemodialysis patients who had amyloid β protein (Aβ) removed from their blood three times a week. One major pathological change in the brain associated with AD is Aβ deposition, mainly 40 amino acids Aβ1-40 and 42 amino acids Aβ1-42. Impaired Aβ clearance is proposed to be one cause of increased Aβ in the AD brain. Thus, we hypothesized that an extracorporeal removal system of Aβ from the blood may remove brain Aβ and be a useful therapeutic strategy for AD. In the first prospective study, plasma Aβ levels and the cognitive function of 30 hemodialysis patients (65-76 years old) were evaluated at baseline as well as 18 or 36 months after. Although plasma Aβ1-40 levels either decreased or remained unchanged, levels of Aβ1-42 either remained unchanged or increased at the second time point. Mini-Mental State Examination scores of most subjects increased or were maintained at the second time point. Aβ1-40 influx into the blood correlated with MMSE at the second time point. In the second prospective study, five patients (51-84 years old) with renal failure were evaluated before and after the initiation of hemodialysis. Plasma Aβ levels decreased, while cognitive function improved after initiating blood Aβ removal. Therefore, long-term hemodialysis, which effectively removes blood Aβ, might alter Aβ influx and help maintain cognitive function.

Long lesions have been associated with adverse outcomes in percutaneous coronary interventions with bare metal stents (BMS). However, the exact impact of lesion length on the short- and long-term outcomes of drug-eluting stent (DES) implantations is not as clear. This study compared the impact of lesion length on angiographic and clinical outcomes of BMS and DES in a single-center prospective registry. Lesion length was divided into tertiles. The primary endpoints were angiographically defined binary in-stent restenosis (ISR) rate and major adverse cardiac event (MACE). Of the 4,312 de novo lesions in 3,447 consecutive patients in the CAPTAIN registry, 2,791 lesions (of 2,246 patients) received BMS, and the remaining 1,521 lesions (of 1,201 patients) received DES. The mean follow-up duration was 4.5 years. The longer the lesion, the higher the ISR rate (14%, 18%, and 29%, p<0.001) and the lower the MACE-free survivals (p = 0.007) in the BMS group. However, lesion length showed no such correlation with ISR rates (4.7%, 3.3%, and 7.8%, p = 0.67) or MACE-free survivals (p = 0.19) in the DES group. In our single-center prospective registry, lesion length defined in tertiles has no impact on the short-term (ISR) or long-term (MACE) outcomes of patients implanted with DES. In contrast, longer lesion correlates with higher ISR and MACE rates in BMS group.

Long-term mortality after community-acquired pneumonia—impacts of diabetes and newly discovered hyperglycaemia: a prospective, observational cohort study

Objectives Community-acquired pneumonia is associated with a significant long-term mortality after initial recovery. It has been acknowledged that additional research is urgently needed to examine the contributors to this long-term mortality. The objective of the present study was to assess whether diabetes or newly discovered hyperglycaemia during pneumonia affects long-term mortality. Design A prospective, observational cohort study. Setting A single secondary centre in eastern Finland. Participants 153 consecutive hospitalised patients who survived at least 30 days after mild-to-moderate community-acquired pneumonia. Interventions Plasma glucose levels were recorded seven times during the first day on the ward. Several possible confounders were also recorded. The surveillance status and causes of death were recorded after median of 5 years and 11 months. Results In multivariate Cox regression analysis, a previous diagnosis of diabetes among the whole population (adjusted HR 2.84 (1.35–5.99)) and new postprandial hyperglycaemia among the non-diabetic population (adjusted HR 2.56 (1.04–6.32)) showed independent associations with late mortality. New fasting hyperglycaemia was not an independent predictor. The mortality rates at the end of follow-up were 54%, 37% and 10% among patients with diabetes, patients without diabetes with new postprandial hyperglycaemia and patients without diabetes without postprandial hyperglycaemia, respectively (p<0.001). The underlying causes of death roughly mirrored those in the Finnish general population with a slight excess in mortality due to chronic respiratory diseases. Pneumonia was the immediate cause of death in just 8% of all late deaths. Conclusions A previous diagnosis of diabetes and newly discovered postprandial hyperglycaemia increase the risk of death for several years after community-acquired pneumonia. As the knowledge about patient subgroups with an increased late mortality risk is gradually gathering, more studies are needed to evaluate the possible postpneumonia interventions to reduce late mortality.

Gathercole, Susan E; Briscoe, Josie; Thorn, Annabel; Tiffany, Claire

2008-03-01

Possible links between phonological short-term memory and both longer term memory and learning in 8-year-old children were investigated in this study. Performance on a range of tests of long-term memory and learning was compared for a group of 16 children with poor phonological short-term memory skills and a comparison group of children of the same age with matched nonverbal reasoning abilities but memory scores in the average range. The low-phonological-memory group were impaired on longer term memory and learning tasks that taxed memory for arbitrary verbal material such as names and nonwords. However, the two groups performed at comparable levels on tasks requiring the retention of visuo-spatial information and of meaningful material and at carrying out prospective memory tasks in which the children were asked to carry out actions at a future point in time. The results are consistent with the view that poor short-term memory function impairs the longer-term retention and ease of learning of novel verbal material.

Background/Aims Benzimidazoles are efficacious for treating non-resectable alveolar echinococcosis (AE), but their long-term parasitocidal (curative) effect is disputed. In this study, we prospectively analyzed the potential parasitocidal effect of benzimidazoles and whether normalization of FDG-PET/CT scans and anti-Emll/3-10-antibody levels could act as reliable "in vivo" parameters of AE-inactivation permitting to abrogate chemotherapy with a low risk for AE-recurrence. Method This prospective study included 34 patients with non-resectable AE subdivided into group A (n = 11), followed-up after diagnosis and begin of chemotherapy at months 6, 12 and 24, and group B (n = 23) with a medium duration of chemotherapy of 10 (range 2–25) years. All patients were assessed by FDG-PET/CT examinations and anti-EmII/3-10 serology. Chemotherapy was abrogated in patients with normalization of FDG-PET/CT and serum anti-EmII/3-10 levels. These patients were closely followed-up for AE recurrence. Endpoint (parasitocidal efficacy) was defined by the absence of AE-recurrence >24 months after stopping treatment. Results Normalization of FDG-PET/CT scan and anti-EmII/3-10 levels occurred in 11 of 34 patients (32%). After abrogation of chemotherapy in these 11 patients, there was no evidence of AE-recurrence within a median of 70.5 (range 16–82) months. However, the patients’ immunocompetence appears pivotal for the described long-term parasitocidal effect of benzimidazoles. Conclusions The combination of negative FDG-PET/CT-scans and anti-EmII/3-10 antibody levels seem to be reliable parameters for assessing in vivo AE-larval inactivity after long-term benzimidazole chemotherapy.

Navigated computer-assisted total knee arthroplasty (TKA) was introduced to expedite long-term survival based on improved postoperative implantation accuracy. However, long-term outcome data after 10 years or more are rare, even available meta-analyses show controversial study results. In a prospective randomized trial, 100 conventional TKAs (group CONV) were compared with 100 computer-assisted TKAs (group NAV) after a mean follow-up of 12 years postoperatively. A long-leg weight-bearing X-ray was performed for measuring mechanical axis of the limb, lateral distal femoral angle, and medial proximal tibial angle. Tibial slope, patella alpha angle, and radiolucent lines were also observed. Clinical investigation included evaluation of 4 different scores: Insall Knee Score, Western Ontario and MacMaster University Index score, Hospital for Special Surgery Knee Score, and visual analog scale. Based on a follow-up rate of at least 75%, no difference in TKA survival was found 12 years postoperatively: 91.5% in group CONV vs 98.2% in group NAV (P = .181). Since 5-year follow-up, no additional TKA revision had been performed in both groups. Group CONV showed a nonsignificant higher inaccuracy of neutral lower limb axis (1.8° ± 1.4°) compared to group NAV (1.6° ± 1.7°, P = .700). All X-ray assessments were not significant different within both study groups (P ≥ .068). Clinical examination showed no differences in evaluations (P ≥ .204). All collected outcome score results were similar (P ≥ .222). Twelve years postoperatively, no differences were found in terms of long-term survival, implantation accuracy, clinical outcome or score results. Copyright © 2017 Elsevier Inc. All rights reserved.

Standard knowledge delivery formats for CME may have limited impact on long-term practice change. A community of practice (CoP) is one tool that may enhance competencies and support practice change. This study explores the utility of an interprofessional CoP as an adjunct to a CME program in tobacco addiction treatment (Training Enhancement in Applied Counselling and Health [TEACH] Project) to promote and sustain practice change. A prospective cohort design was utilized to examine the long-term impact of the TEACH CoP on practice change. An online survey was administered to TEACH-trained practitioners to assess perceived feasibility, importance, and confidence related to course competencies, involvement in TEACH CoP activities, engagement in knowledge transfer (KT), and implementation of new programming. Chi-square tests were used to detect differences in KT and program development associated with CoP participation. Course competency scores from immediate postcourse surveys and long-term follow-up surveys were compared. No significant differences in participant characteristics were found between those who did (n = 300) and did not (n = 122) participate in the TEACH CoP. Mean self-perceived competency scores were greater immediately after course than at long-term follow-up; however, self-ratings of competency in pharmacological interventions and motivational interviewing were higher at follow-up. TEACH CoP participation was associated with significantly greater engagement in KT and implementation of new programming after training. The findings from this evaluation suggest the value of interprofessional CoPs offered posttraining as a mechanism to enhance practice. CME providers should consider offering CoPs as a component of training programs to promote and sustain practice change.

The real efficacy of selenium supplementation in Hashimoto's thyroiditis (HT) is still an unresolved issue. We studied the short-term effect of L-selenomethionine on the thyroid function in euthyroid patients with HT. Our primary outcome measures were TSH, thyroid hormones, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb) levels and thyroid echogenicity after 6 months of L-selenomethionine treatment. The secondary outcome measure was serum CXCL10 levels. In a placebo-controlled randomized prospective study, we have enrolled untreated euthyroid patients with HT. Seventy-six patients were randomly assigned to receive L-selenomethionine 166 µg/die (SE n = 38) or placebo (controls n = 38) for 6 months. TSH, free T 4 (FT 4 ), free T 3 (FT 3 ), TPOAb and CXCL10 serum levels were assayed at time 0, after 3 and 6 months. An ultrasound examination of the left and right thyroid lobe in transverse and longitudinal sections was performed. A rectangular region, the region of interest, was selected for analysis. TSH, FT4, FT3, TPOAb, thyroid echogenicity and CXCL10 were not statistically different between SE and control groups at time 0, after 3 and 6 months. In the SE group, FT 4 levels were significantly decreased (P < 0.03) after 3 months, while FT 3 increased (P < 0.04) after 3 and 6 months versus baseline values. In the control group, the FT 3 decreased after 3 and 6 months (P < 0.02) compared to baseline. The short-term L-selenomethionine supplementation has a limited impact on the natural course in euthyroid HT. Our results tip the balance toward the ineffectiveness of short-term L-selenomethionine supplementation in HT.

Most cross-sectional studies have found a significant positive relationship between periodontal disease and prehypertension/hypertension. However, these studies had limitations and there are few prospective cohort studies in young adults. The purpose of this prospective cohort study was to investigate whether periodontal disease was related to prehypertension/hypertension in Japanese university students. Students (n = 2,588), who underwent health examinations before entering university and before graduation, were included in the analysis. The association between periodontal disease such as the percentage of bleeding on probing (BOP) and community periodontal index (CPI) scores, and change in blood pressure status was determined. At the reexamination, the numbers of participants with prehypertension (systolic blood pressure 120-139mm Hg or diastolic blood pressure 80-89mm Hg) and hypertension (≥140/90mm Hg) were 882 (34.1%) and 109 (4.2%), respectively. In a logistic regression model, the risk of hypertension was significantly associated with male (odds ratio (OR): 6.31; 95% confidence interval (CI): 2.63-15.13; P < 0.001), no habitual physical activity at baseline (OR: 2.90; 95% CI: 1.56-5.38; P < 0.01) and periodontal disease defined as the presence of both probing pocket depth (PPD) ≥ 4mm and BOP ≥ 30% at baseline (OR: 2.74; 95% CI: 1.19-6.29; P = 0.02) in participants with prehypertension at baseline. On the other hand, the risk of prehypertension was not associated with presence of periodontal disease (OR: 0.93; 95% CI: 0.51-1.70; P = 0.82). In the short-term prospective cohort study, a significant association between presence of periodontal disease and hypertension was observed in Japanese university students. © American Journal of Hypertension, Ltd 2015.

To describe adverse event reporting processes in long-term care facilities in the Czech Republic. Prospective cohort study involving a written questionnaire followed by in-person structured interviews with selected respondents. Long-term care facilities located in the Czech Republic. Staff of 111 long-term care facilities (87% of long-term care facilities in the Czech Republic). None. Sixty-three percent of long-term health-care facilities in the Czech Republic have adverse event-reporting processes already established, but these were frequently very immature programs sometimes consisting only of paper recording of incidents. Compared to questionnaire responses, in-person interview responses only partially tended to confirm the results of the written survey. Twenty-one facilities (33%) had at most 1 unconfirmed response, 31 facilities (49%) had 2 or 3 unconfirmed responses and the remaining 11 facilities (17%) had 4 or more unconfirmed responses. In-person interviews suggest that use of a written questionnaire to assess the adverse event-reporting process may have limited validity. Staff of the facilities we studied expressed an understanding of the importance of adverse event reporting and prevention, but interviews also suggested a lack of knowledge necessary for establishing a good institutional reporting system in long-term care.

Blonanserin: a review of its use in the management of schizophrenia.

PubMed

Deeks, Emma D; Keating, Gillian M

2010-01-01

Oral blonanserin (Lonasen) is an atypical antipsychotic agent indicated for use in patients with schizophrenia in Japan and Korea. It is effective in the treatment of patients with schizophrenia, providing short- and long-term efficacy against both the positive and negative symptoms of the disorder in several randomized and noncomparative trials. Notably, in two randomized, double-blind trials of 8 weeks' duration, blonanserin was noninferior to haloperidol or risperidone for primary endpoints, although it appeared to be better than haloperidol in improving negative symptoms. Blonanserin is generally well tolerated and appears to have an acceptable profile in terms of bodyweight gain. Potential tolerability benefits of the drug in short-term trials included fewer extrapyramidal symptoms than haloperidol and fewer reports of prolactin level increases or hyperprolactinaemia than risperidone. Nevertheless, extrapyramidal symptoms and hyperprolactinaemia were among the most common adverse reactions associated with blonanserin in noncomparative long-term studies. Further prospective and long-term comparative studies are required in order to definitively position blonanserin with respect to other antipsychotic agents. In the meantime, available clinical data suggest that blonanserin is an effective and generally well tolerated option for the short-term treatment of schizophrenia and for those requiring longer-term therapy.

No consensus had been reached about the optimal method for syndesmotic fixation. The present study analysed syndesmotic fixation based on the highest level of clinical evidence in order to obtain more reliable results. Medline, Embase and Cochrane database were searched through the OVID retrieval engine. Manual searching was undertaken afterward to identify additional studies. Only randomized controlled trials (RCT) and prospective comparative studies were selected for final inclusion. Study screening and data extraction were completed independently by two reviewers. All study characteristics were summarized into a table. The extracted data were used for data analysis. Twelve studies were finally included: six of them were RCTs, two were quasi-randomized studies and four were prospective comparative studies. Four comparisons with traditional metallic screw were identified in terms of bioabsorbable screws, tricortical fixation method, suture-button device as well as non-fixation choice in low syndesmotic injuries. Both absorbable screws and the tricortical fixation method showed almost no better results than traditional quadricortical metallic screw (p > 0.05). Additionally, existing studies could not illustrate their efficiency of reducing hardware removal rate. The suture button technique had significantly better functional score (p = 0.003), ankle motion (p = 0.02), time to full weightbearing (p < 0.0001) and much less complications (p = 0.0008) based on short and intermediate term follow-up data. Transfixation in low syndesmotic injuries showed poorer results than the non fixed group in all outcome measurements, but didn't reach a significant level (p > 0.05). The present evidence still couldn't find superior performance of the bioabsorbable screw and tricortical fixation method. Their true effects in decreasing second operation rate need further specific studies. Better results of the suture-button made it a promising technique, but it still needs long-term testing and cost-efficiency studies. The patients with low syndemotic injuries should be well assessed before fixation determination and the indication of screw placement in such conditions needs to be further defined.

Surgical Heller myotomy has high rates of successful long-term results, but failed cases still remain. Moreover, the treatment strategy in patients with surgical myotomy failure is controversial. Recently, peroral endscopic myotomy (POEM) was reported to be efficient and safe in primary treatment of achalasia. In this study, we aimed to evaluate the efficacy and safety of POEM for surgical myotomy failure as a rescue second-line treatment, and we discuss the treatment options adapted in achalasia recurrence. A total of 315 consecutive achalasia patients received POEM from September 2008 to December 2012 in our hospital. Eleven (3.5%) patients who had persistent or recurrent achalasia and had received surgical myotomy as a first-line treatment from other hospitals were included in this study. Patient background, barium swallow studies, esophagogastroduodenoscopy (EGD), manometry, and symptom scores were prospectively evaluated. In principle, all patients in whom surgical myotomy failed received pneumatic balloon dilatation (PBD) as the first line "rescue" treatment, and only if PBD failed were patients considered for rescue POEM. The PBD alone was effective in 1 patient, and in the remaining 10 patients, rescue POEM was performed successfully without complications. Three months after rescue POEM, significant reduction in lower esophageal sphincter (LES) resting pressures (22.1 ± 6.6 mmHg vs 10.9 ± 4.5 mmHg, p < 0.01) and Eckardt symptom scores (6.5 ± 1.3 vs 1.1 ± 1.3, p < 0.001) were observed. Short-term results of POEM for failed surgical myotomy were excellent. Long-term results are awaited. Copyright © 2013 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

We evaluate whether aspiration and sclerosing of hydrocele testis is an effective treatment. Men with symptomatic hydrocele testis were included in this prospective, double-blind, randomized study with polidocanol and placebo. Patients were randomized to active treatment or placebo at the first treatment. Depending on hydrocele testis size (less than 100, 100 to 200 and greater than 200 ml), the patients were treated with 1, 3 or 4 ml polidocanol after aspiration. Patients with recurrence at the 5-week followup received active treatment. A total of 77 patients were included in the study. In group 1 (active treatment) there were 36 patients with a median age of 63 years (range 34 to 92). In group 2, comprised of 41 patients, the median age was 59 years (range 26 to 82). Median followup was 72 months. A significant difference between the groups was observed after the first and second treatments. Recurrence after the first treatment was seen in 16 (44%) patients from group 1 and in 32 (78%) from group 2 (p <0.05). Recurrence after re-treatment with the active drug in both groups was seen in 4 (25%) patients in group 1 and in 14 (44%) in the former placebo group (p <0.05). The overall success rate of treatment in the active group was 89%. There was no difference between the 2 groups in terms of volume of fluid aspirated, symptoms or complications. This long-term efficacy randomized study with placebo showed that polidocanol is effective for the treatment of hydrocele testis with a low recurrence rate.

A randomized, double-blind, 24-week-fixed-dose study comparing the efficacy and safety of escitalopram to that of citalopram was safety was conducted in primary care patients with moderate to severe major depressive disorder (MDD). This was a randomized, double-blind, 24-week fixeddose study. Patients were randomly assigned to treatment with escitalopram 10 mg/day (n = 175) or citalopram 20 mg/day (n = 182). Clinical response was evaluated using the Montgomery-Asberg Depression Rating Scale (MADRS) and Clinical Global Impression-Severity (CGI-S) scale. The prospectively defined primary parameter of antidepressant efficacy was the change from baseline in the mean MADRS total score during the 24 weeks of double-blind treatment, using a repeated measures analysis of variance to compare the treatment groups over all assessment points simultaneously. Based on the primary parameter, escitalopram was at least as efficacious as citalopram. Based on the prospectively defined secondary parameter, mean change from baseline in the CGI-S score, escitalopram was statistically significantly superior to citalopram at Week 24. The importance of long-term treatment could be demonstrated, in that more than half (55% and 51%) of the patients who had not responded by Week 8 achieved remission by Week 24. Both escitalopram and citalopram were safe and well tolerated in acute and long-term treatment, and the overall adverse event profiles for the two drugs were similar. For the intent-to-treat population, there were statistically significantly fewer withdrawals in the escitalopram group than in the citalopram group, particularly after Week 8. Patients with MDD responded well to long-term treatment with either escitalopram or citalopram. This study demonstrated the importance of extending treatment of depression beyond 8 weeks.

Concurrent chemoradiotherapy (CCRT) for advanced head and neck cancer (HNC) is associated with substantial early and late side effects, most notably regarding swallowing function, but also regarding voice quality and quality of life (QoL). Despite increased awareness/knowledge on acute dysphagia in HNC survivors, long-term (i.e., beyond 5 years) prospectively collected data on objective and subjective treatment-induced functional outcomes (and their impact on QoL) still are scarce. The objective of this study was the assessment of long-term CCRT-induced results on swallowing function and voice quality in advanced HNC patients. The study was conducted as a randomized controlled trial on preventive swallowing rehabilitation (2006-2008) in a tertiary comprehensive HNC center with twenty-two disease-free and evaluable HNC patients as participants. Multidimensional assessment of functional sequels was performed with videofluoroscopy, mouth opening measurements, Functional Oral Intake Scale, acoustic voice parameters, and (study specific, SWAL-QoL, and VHI) questionnaires. Outcome measures at 6 years post-treatment were compared with results at baseline and at 2 years post-treatment. At a mean follow-up of 6.1 years most initial tumor-, and treatment-related problems remained similarly low to those observed after 2 years follow-up, except increased xerostomia (68%) and increased (mild) pain (32%). Acoustic voice analysis showed less voicedness, increased fundamental frequency, and more vocal effort for the tumors located below the hyoid bone (n = 12), without recovery to baseline values. Patients' subjective vocal function (VHI score) was good. Functional swallowing and voice problems at 6 years post-treatment are minimal in this patient cohort, originating from preventive and continued post-treatment rehabilitation programs.

The aim of this study was to compare between the short-term results of onlay and sublay mesh placement in the prosthetic repair of uncomplicated para-umbilical hernia (PUH). Eighty patients with a defect size ranging from 4 to 10 cm were prospectively randomized to either the onlay group (40 patients) or the sublay group (40 patients). The operative time, postoperative complications and short-term recurrence were reported. There were no statistically significant differences between both study groups as regards the patients' demographics, associated co-morbidities and mean defect size. The median operative time was significantly shorter in the onlay group compared to that in the sublay group (52 vs. 91 min respectively, p < 0.001). No statistically significant difference was found in the daily median pain score throughout the first postoperative week. The time required to remove the suction drain was significantly shorter in the sublay group compared to that in the onlay group (3 vs. 7 days respectively, p < 0.001).Complications were encountered in 4 patients (10%) in the onlay group compared to 3 patients (7.5%) in the sublay group (p = 1.000). Superficial wound infection was encountered in 1 patient (2.5%) in the sublay group, Seroma was encountered in 2 patients (5%) in the onlay group, Deep vein thrombosis was encountered in 1 patient (2.5%) in the onlay group, Chest infection was encountered in 2 patients (5%) in the sublay group compared to 1 patient (2.5%) in the onlay group. Throughout the 22 months median follow-up duration (range 6-42 months), 2 recurrences (5%) were encountered in either study group. Both techniques are safe, efficient and are associated with comparable complication and recurrence rates.

Patients with epilepsy are at risk of traffic accidents when they have seizures while driving. However, driving is an essential part of normal daily life in many communities, and depriving patients of driving privileges can have profound consequences for their economic and social well being. In the current study, we collected ictal performance data from a driving simulator and two other video games in patients undergoing continuous video/EEG monitoring. We captured 22 seizures in 13 patients and found that driving impairment during seizures differed both in terms of magnitude and character, depending on the seizure type. Our study documents the feasibility of the prospective study of driving and other behaviors during seizures through the use of computer-based tasks. This methodology may be applied to further describe differential driving impairment in specific types of seizures and to gain data on anatomical networks disrupted in seizures that impair consciousness and driving safety.

Emotional dysfunction is by definition central to personality disorders (PDs). In the alternative model in DSM-5, self and relational dysfunctioning constitutes the core of PD, but little is known about the relation between emotional functioning and such core aspects of personality functioning. This study investigated concurrent and prospective associations between emotional and personality functioning as assessed by affect consciousness (AC) and the Severity Indices of Personality Problems (SIPP-118), respectively. The SIPP-118 comprises five domains of personality functioning, including Identity Integration and Relation Capacities, and was applied repeatedly during 3-year follow-up of 63 PD patients who participated in a treatment study. Statistical analyses were based on linear mixed models. Lower AC levels were significantly associated with (a) lower levels of Identity Integration and Relational Capacities at baseline, and (b) poorer long-term improvement of Identity Integration. The study supports the notion that affect consciousness is related to core aspects of personality functioning.

Public- and private-sector initiatives to promote healthy eating and physical activity, called 'healthy lifestyles', are a relatively recent response to the global obesity pandemic. The present paper explores different views about marketing healthy lifestyles with a special emphasis on private-sector initiatives and public-private partnerships designed to reach young people. We discuss aspects of these initiatives and partnerships from three perspectives: (i) the potential for commercial marketing practices to have a favourable influence on reversing global obesity trends (termed prospects); (ii) unresolved dilemmas and challenges that may hinder progress (termed pitfalls); and (iii) the implementation and evaluation of coordinated and systematic actions (termed priorities) that may increase the likelihood that commercially marketed healthy-lifestyle initiatives and public-private partnerships can make a positive contribution to reverse the rise in overweight and obesity among young people globally.

Bruxism in prospective studies of veneered zirconia restorations-a systematic review.

2014-01-01

The objectives of this work were to systematically review the effect of bruxism on the survival of zirconia restorations on teeth and to assess the prevalence of nocturnal masseter muscle activity in a clinical sample. A Medline search was performed independently and in triplicate using the term "zirconia" and activating the filter "clinical trial." Furthermore, three other electronic databases were searched using the same term. Only papers published in English on prospective studies of veneered zirconia frameworks on teeth were included. To estimate the prevalence of sleep bruxism in clinical settings, subjects with no clinical signs of bruxism and who did not report grinding and/or clenching were examined by use of a disposable electromyographic device. The initial search resulted in 107 papers, of which 22 were included in the analysis. Bruxers were excluded in 20 of these articles. In 1 study bruxers were not excluded, and 1 study did not provide information regarding this issue. The methods used to identify bruxers were heterogeneous/not described, and no study used reliable, valid methods. Of 33 subjects without clinical signs of bruxism, nocturnal muscle activity exceeded predefined muscle activity for 63.8% of the subjects. There is a lack of information about the effect of bruxism on the incidence of technical failure of veneered zirconia restorations because all available studies failed to use suitable instruments for diagnosis of bruxism. Nocturnal muscle activity without clinical symptoms/report of bruxism was observed for a relevant number of patients.

Venous thromboembolism (VTE), a disease that includes deep venous thrombosis (DVT) and pulmonary embolism (PE), is associated with high mortality, morbidity, and costs. It can result in long-term complications that include postthrombotic syndrome (PTS) adding to its morbidity. VTE affects 1/1000 patients, costs $13.5 billion annually to treat, and claims 100,000 lives annually in the US. The current standard of care for VTE is anticoagulation, though thrombolysis may be performed in patients with PE and threatened limb. This review discusses pathogenesis and medical treatment of VTE and then focuses on endovascular treatment modalities. Mechanical- and catheter-directed thrombolysis (CDT) is discussed, as well as patient selection criteria, and complications. The first prospective study (CaVenT) comparing CDT with anticoagulation alone in acute DVT, despite study shortcomings, corroborates the existing literature indicating improved outcomes with CDT. The potential of the ongoing prospective, multicenter, randomized ATTRACT trial is also highlighted. PMID:28154761

The present study investigated the effects of divorce and family relations on young children's development prospectively, using an ethnically diverse sample of approximately 300 low-income families. We also were able to examine the moderating effects of ethnicity on child adjustment in always two-parent, to-be-divorced, already-divorced, and always single-parent families. Results indicated that to-be-divorced European American and African American families demonstrated higher rates of preschool-age behavior problems, and already-divorced families showed similar trends. Parental conflict and behavior problems accounted for predivorce differences in child behavior problems, whereas rejecting parenting accounted for differences in problem behavior between always single-parent and always two-parent families. The results are discussed in terms of the importance of ethnicity in influencing young, low-income children's adjustment to different family structures.

Pedagogical Content Knowledge Development and Pre-Service Physics Teacher Education: A Case Study

NASA Astrophysics Data System (ADS)

Sperandeo-Mineo, R. M.; Fazio, C.; Tarantino, G.

2006-09-01

This paper addresses the question of how to develop prospective teachers' pedagogical content knowledge (PCK) in science teacher education. The main focus is on the knowledge transformation process and on the cognitive strategies used to shift prospective teachers' explanations within the domain of modelling thermal physical phenomena. This study investigates the development of PCK within a group of 28 pre-service physics teachers during the first semester of their two-year post-graduate teacher education program. It focuses on the central issue of the relationships between observable phenomena, like macroscopic thermal properties of matter and their interpretation and/or explanation in terms of corpuscular characteristics and/or thermodynamics theory. The strategy is based on the consideration that knowledge transformation is not a one-way process from subject matter knowledge to pedagogical content knowledge, as literature suggests, but a bidirectional process involving deepening of subject matter knowledge and increasing awareness of pedagogical issues.

Multiple sclerosis (MS) is associated with prospective memory (PM) deficits, which may increase the risk of poor functional/health outcomes such as medication non-adherence. This study examined the potential benefits of selective reminding to enhance PM functioning in persons with MS. Twenty-one participants with MS and 22 healthy adults (HA) underwent a neuropsychological battery including a Selective Reminding PM (SRPM) experimental procedure. Participants were randomly assigned to either: (1) a selective reminding condition in which participants learn (to criterion) eight prospective memory tasks in a Selective Reminding format; or (2) a single trial encoding condition (1T). A significant interaction was demonstrated, with MS participants receiving greater benefit than HAs from the SR procedure in terms of PM performance. Across diagnostic groups, participants in the SR conditions (vs. 1T conditions) demonstrated significantly better PM performance. Individuals with MS were impaired relative to HAs in the 1T condition, but performance was statistically comparable in the SR condition. This preliminary study suggests that selective reminding can be used to enhance PM cue detection and retrieval in MS. The extent to which selective reminding of PM is effective in naturalistic settings and for health-related behaviours in MS remains to be determined.

The objective of the study was to evaluate the efficacy of antibiotic prophylaxis in women with term or near-term premature rupture of membranes. Searches were performed in MEDLINE, OVID, Scopus, ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, EMBASE, ScienceDirect.com, MEDSCAPE, and the Cochrane Central Register of Controlled Trials with the use of a combination of key words and text words related to antibiotics, premature rupture of membranes, term, and trials from inception of each database to September 2014. We included all randomized trials of singleton gestations with premature rupture of membranes at 36 weeks or more, who were randomized to antibiotic prophylaxis or control (either placebo or no treatment). The primary outcomes included maternal chorioamnionitis and neonatal sepsis. A subgroup analysis on studies with latency more than 12 hours was planned. Before data extraction, the review was registered with the PROSPERO International Prospective Register of Systematic Reviews (registration number CRD42014013928). The metaanalysis was performed following the Preferred Reporting Item for Systematic Reviews and Meta-analyses statement. Women who received antibiotics had the same rate of chorioamnionitis (2.7% vs 3.7%; relative risk [RR], 0.73, 95% confidence interval [CI], 0.48-1.12), endometritis (0.4% vs 0.9%; RR, 0.44, 95% CI, 0.18-1.10), maternal infection (3.1% vs 4.6%; RR, 0.48, 95% CI, 0.19-1.21), and neonatal sepsis (1.0% vs 1.4%; RR, 0.69, 95% CI, 0.34-1.39). In the planned subgroup analysis, women with latency longer than 12 hours, who received antibiotics, had a lower rate of chorioamnionitis (2.9% vs 6.1%; RR, 0.49, 95% CI, 0.27-0.91) and endometritis (0% vs 2.2%; RR, 0.12, 95% CI, 0.02-0.62) compared with the control group. Antibiotic prophylaxis for term or near-term premature rupture of membranes is not associated with any benefits in either maternal or neonatal outcomes. In women with latency longer than 12 hours, prophylactic antibiotics are associated with significantly lower rates of chorioamnionitis by 51% and endometritis by 88%. Copyright © 2015 Elsevier Inc.

The aim of this study was to investigate the long-term intraocular pressure (IOP)-lowering effect and safety of tafluprost, a prostaglandin analogue, in actual clinical practice and to determine persistency of tafluprost as an indicator of its benefit-risk balance. This was a large-scale, post-marketing, multicenter, non-interventional, open-label, long-term study. Patients with glaucoma or ocular hypertension who initiated tafluprost treatment were registered and prospectively observed over a 2-year period in the real-world setting in Japan. Long-term IOP and safety data were collected. Of the 4502 patients registered from 553 medical institutions, 4265 patients were analyzed. The majority of patients had normal-tension glaucoma (44.4%) and primary open-angle glaucoma (37.8%), and patients with ocular hypertension constituted 7.0%. Treatment patterns with tafluprost during the study period were as follows: naïve monotherapy (48.1%), switching monotherapy (18.4%), and concomitant therapy (33.5%). In all patients analyzed, mean IOP was significantly reduced from 18.6 ± 5.9 mmHg (month 0) to 15 mmHg or below throughout the 2-year observation period after initiation of tafluprost. Significant IOP-lowering effects were shown in various treatment patterns and disease types. Adverse reactions were observed in 795 patients (18.64%). Major adverse reactions included eyelid pigmentation, ocular hyperemia, eyelash changes, eyelid hypertrichosis, and iris hyperpigmentation. Kaplan-Meier curves showed that 84.6% and 76.1% of patients were persistent on tafluprost for 1 and 2 years, respectively, when discontinuation due to insufficient efficacy or adverse events was defined as a treatment failure event. Furthermore, among treatment-naïve patients (n = 2304), the persistency rates on tafluprost monotherapy were 77.0% for 1 year and 67.0% for 2 years. Tafluprost showed significant long-term IOP-lowering effects regardless of treatment patterns or diagnosis, with minimum safety concerns in the actual clinical practice. The observed treatment persistence suggests that tafluprost can be used long term owing to its benefit-risk profile. Santen Pharmaceutical Co., Ltd., Osaka, Japan.

Protecting children from the consequences of divorce: a longitudinal study of the effects of parenting on children's coping processes.

Vélez, Clorinda E; Wolchik, Sharlene A; Tein, Jenn-Yun; Sandler, Irwin

2011-01-01

This study examines whether intervention-induced changes in mother-child relationship quality and discipline led to short-term (6 months) and long-term (6 years) changes in children's coping processes in a sample of 240 youth aged 9-12 years when assessed initially. Data were from a randomized, experimental trial of a parenting-focused preventive intervention designed to improve children's postdivorce adjustment. Three-wave prospective mediational analyses revealed that intervention-induced improvements in relationship quality led to increases in coping efficacy at 6 months and to increases in coping efficacy and active coping at 6 years. Tests of the mediated effects were significant for all 3 indirect paths. Results are discussed in terms of pathways to adaptive coping and implications for the implementation of preventive interventions targeting coping. © 2011 The Authors.

Prospects and applicability of wave energy for South Africa

NASA Astrophysics Data System (ADS)

Lavidas, George; Venugopal, Vengatesan

2018-03-01

Renewable energy offers significant opportunities for electricity diversification. South Africa belongs to the group of developing nations and encompasses a lot of potential for renewable energy developments. Currently, the majority of its electricity production originates from fossil fuels; however, incorporation of clean coal technologies will aid in reaching the assigned targets. This study offers a long-term wave power quantification analysis with a numerical wave model. The investigation includes long-term resource assessment in the region, variability, seasonal and monthly wave energy content. Locations with high-energy content but low variability pose an opportunity that can contribute in the alleviation of energy poverty. Application of wave converters depends on the combination of complex terms. The study presents resource levels and the joint distributions, which indicate suitability for converter selection. Depending on the region of interest, these characteristics change. Thus, this resource assessment adds knowledge on wave power and optimal consideration for wave energy applicability.

In gastric MALT lymphomas persisting after Helicobacter pylori (H. pylori) eradication, a treatment by moderate-dose radiotherapy (RT) has been proposed but its efficacy has not been confirmed in large prospective series with long term endoscopic follow-up. Patients with localised gastric MALT lymphoma persisting after H. pylori eradication were offered moderate-dose RT (30Gy, 2Gy/fraction) and followed with annual endoscopies. All biopsies before and after RT were reviewed by a committee of pathologists. From 1995 to 2011, out of the 232 patients followed prospectively, 53 received RT for persistence of lymphoma after H. pylori eradication: either macroscopic ulcer (n=31), or microscopic lymphomatous infiltrate (n=22), after a mean follow-up of 12 and 31months, respectively. All lymphomas were localised (45 stage IE and 8 stage IIE) and 38 (72%) were H. pylori-positive. The mean clinical and endoscopic follow-up from diagnosis was 7.6years (2.2-19.1). No acute or late toxicity occurred. A complete remission was achieved in all patients but one (98%) with no relapse after a median follow-up of 4.9years (1.3-16.6) after completion of RT. Overall survival and 5-year disease specific survival were 94% and 100%, respectively. One patient died of gastric adenocarcinoma. Moderate-dose RT (30Gy) is effective and safe for localised gastric MALT lymphoma persisting after H. pylori eradication. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Adult neurobehavioral outcome of hyperbilirubinemia in full term neonates-a 30 year prospective follow-up study.

Hokkanen, Laura; Launes, Jyrki; Michelsson, Katarina

Background. Neonatal hyperbilirubinemia (HB) may cause severe neurological damage, but serious consequences are effectively controlled by phototherapy and blood exchange transfusion. HB is still a serious health problem in economically compromised parts of the world. The long term outcome has been regarded favorable based on epidemiological data, but has not been confirmed in prospective follow-up studies extending to adulthood. Methods. We studied the long term consequences of HB in a prospective birth cohort of 128 HB cases and 82 controls. The cases are part of a neonatal at-risk cohort (n = 1196) that has been followed up to 30 years of age. HB cases were newborns ≥ 2500 g birth weight and ≥ 37 weeks of gestation who had bilirubin concentrations > 340 µmol/l or required blood exchange transfusion. Subjects with HB were divided into subgroups based on the presence (affected HB) or absence (unaffected HB) of diagnosed neurobehavioral disorders in childhood, and compared with healthy controls. Subjects were seen at discharge, 5, 9 and 16 years of life and parent's and teacher's assessments were recorded. At 30 years they filled a questionnaire about academic and occupational achievement, life satisfaction, somatic and psychiatric symptoms including a ADHD self-rating score. Cognitive functioning was tested using ITPA, WISC, and reading and writing tests at 9 years of life. Results. Compared to controls, the odds for a child with HB having neurobehavioral symptoms at 9 years was elevated (OR = 4.68). Forty-five per cent of the HB group were affected by cognitive abnormalities in childhood and continued to experience problems in adulthood. This was apparent in academic achievement (p < 0.0001) and the ability to complete secondary (p < 0.0001) and tertiary (p < 0.004) education. Also, the subgroup of affected HB reported persisting cognitive complaints e.g., problems with reading, writing and mathematics. Childhood symptoms of hyperactivity/impulsivity (p < 0.0001) and inattention (p < 0.02) were more common in HB groups, but in adulthood the symptoms were equal. The affected HB had lower scores in parameters reflecting life satisfaction, less controlled drinking, but not increased substance abuse. Discussion. Our results indicate that neonatal HB has negative consequences in adult age. A prospectively collected cohort with strict inclusion criteria enables to control most of the bias factors involved with retrospective data. The control and HB groups were remarkably similar at birth in terms of medical data, and the growth environment of the children, as well as the parents' social groups, education, size of family, type of housing at birth and at 9 years of age. Our findings bear resemblance to disorders of the fronto-striatal network, and also symptoms of the ADHD spectrum were frequent in the HB group suggesting a link of HB to other neurodevelopmental disorders.

Increasing evidence from lifetime experimental studies in animals and observational and experimental studies in human subjects suggests that pre- and postnatal nutrition programme long-term health. However, key unanswered questions remain on the extent of early-life programming in contemporary European populations, relevant nutritional exposures, critical time periods, mechanisms and the effectiveness of interventions to prevent or reverse programming effects. The EARly Nutrition programming - long-term Efficacy and Safety Trials and integrated epidemiological, genetic, animal, consumer and economic research (EARNEST) consortium brings together a multi-disciplinary team of scientists from European research institutions in an integrated programme of work that includes experimental studies in human subjects, modern prospective observational studies and mechanistic animal work including physiological studies, cell-culture models and molecular techniques. Theme 1 tests early nutritional programming of disease in human subjects, measuring disease markers in childhood and early adulthood in nineteen randomised controlled trials of nutritional interventions in pregnancy and infancy. Theme 2 examines associations between early nutrition and later outcomes in large modern European population-based prospective studies, with detailed measures of diet in pregnancy and early life. Theme 3 uses animal, cellular and molecular techniques to study lifetime effects of early nutrition. Biomedical studies are complemented by studies of the social and economic importance of programming (themes 4 and 5), and themes encouraging integration, communication, training and wealth creation. The project aims to: help formulate policies on the composition and testing of infant foods; improve the nutritional value of infant formulas; identify interventions to prevent and reverse adverse early nutritional programming. In addition, it has the potential to develop new products through industrial partnerships, generate information on the social and economic cost of programming in Europe and help maintain Europe's lead in this critical area of research.

Prospective cohort study of factors influencing the relative weights of the placenta and the newborn infant.

To determine the demographic, environmental, and medical factors that influence the relative weights of the newborn infant and the placenta and compare this ratio with other factors known to predispose to adult ill health. Prospective cohort study. The tertiary referral centre for perinatal care in Perth, Western Australia. 2507 pregnant women who delivered a single live infant at term. Placental weight, birth weight, and the ratio of placental weight to birth weight. By multiple regression analysis the placental weight to birthweight ratio was significantly and positively associated with gestational age, female sex, Asian parentage, increasing maternal body mass index, increased maternal weight at booking, lower socioeconomic status, maternal anaemia, and increasing number of cigarettes smoked daily. There were no consistent relations between the placental weight to birthweight ratio and measures of newborn size. The ratio of placental weight to birth weight is not an accurate marker of fetal growth. In its role as a predictor of adult disease the ratio may be acting as a surrogate for other factors which are already known to influence health and may act before or after birth. Determining the role that relative growth rates of the fetus and placenta have in predisposing to adult disease requires prospective study to account for the many confounding variables which complicate this hypothesis.

The treatment of patients with angina pectoris refractory to medical therapy and unsuitable for revascularization procedures has yet not been well standardized. Previous retrospective studies and small prospective studies have suggested beneficial effects of spinal cord stimulation (SCS) in these patients. We created a Prospective Italian Registry of SCS to evaluate the short- and long-term clinical outcome of patients who underwent SCS device implantation because of severe refractory angina pectoris. Overall, 104 patients were enrolled in the registry (70 men, aged 68 +/- 17 years), most of whom (83%) had severe coronary artery disease. Average follow-up was 13.2 +/- 8 months. Overall, 17 patients (16%) died, 8 (8%) due to cardiac death. Among clinical variables, only age was found to be significantly associated both with total mortality (p = 0.04) and cardiac mortality (p = 0.02) on Cox regression analysis. A significant improvement of anginal symptoms (> or =50% reduction of weekly anginal episodes, compared with baseline) occurred in 73% of patients, and Canadian Cardiovascular Society angina class improved by > or =1 class in 80% and by > or =2 classes in 42% of patients, with a relevant reduction in the rate of hospital admission and days spent in the hospital because of angina (p <0.0001 for both). No life-threatening or clinically serious complications were observed. The most frequent side effect consisted of superficial infections, either at the site of puncture of electrode insertion or of the abdominal pocket, which occurred in 6 patients. In conclusion, our prospective data point out that SCS can be performed safely and is associated with a sustained improvement of anginal symptoms in a relevant number of patients with refractory stable angina pectoris.

In young transgender women previously treated with puberty-suppressing hormones, penoscrotal hypoplasia can make penoscrotal inversion vaginoplasty unfeasible. The aim of this study was to prospectively assess surgical outcomes and follow-up of total laparoscopic sigmoid vaginoplasty as primary reconstruction in a cohort of transgender women with penoscrotal hypoplasia. Baseline demographics, surgical characteristics, and intraoperative and postoperative complications of all performed total laparoscopic sigmoid vaginoplasty procedures were prospectively recorded. From November of 2007 to July of 2015, 42 transgender women underwent total laparoscopic sigmoid vaginoplasty as primary vaginal reconstruction. The mean age at the time of surgery was 21.1 ± 4.7 years. Mean follow-up time was 3.2 ± 2.1 years. The mean operative duration was 210 ± 44 minutes. There were no conversions to laparotomy. One rectal perforation was recognized during surgery and immediately oversewn without long-term consequences. The mean length of hospitalization was 5.7 ± 1.1 days. One patient died as a result of an extended-spectrum beta-lactamase-positive necrotizing fasciitis leading to septic shock, with multiorgan failure. Direct postoperative complications that needed laparoscopic reoperation occurred in three cases (7.1 percent). In seven cases (17.1 percent), long-term complications needed a secondary correction. After 1 year, all patients had a functional neovagina with a mean depth of 16.3 ± 1.5 cm. Total laparoscopic sigmoid vaginoplasty seems to have a similar complication rate as other types of elective laparoscopic colorectal surgery. Primary total laparoscopic sigmoid vaginoplasty is a feasible gender-confirming surgical technique with good functional outcomes for transgender women with penoscrotal hypoplasia. Therapeutic, IV.

Fruit and vegetables consumption and incident hypertension: dose-response meta-analysis of prospective cohort studies.

The role of dietary factors on chronic diseases seems essential in the potentially adverse or preventive effects. However, no evidence of dose-response meta-analysis of prospective cohort studies has verified the association between the intake of fruit and/or vegetables and the risk of developing hypertension. The PubMed and Embase were searched for prospective cohort studies. A generic inverse-variance method with random effects model was used to calculate the pooled relative risks (RRs) and 95% confidence intervals (CIs). Generalized least squares trend estimation model was used to calculate the study-specific slopes for the dose-response analyses. Seven articles comprised nine cohorts involving 185 676 participants were assessed. The highest intake of fruit or vegetables separately, and total fruit and vegetables were inversely associated with the incident risk of hypertension compared with the lowest level, and the pooled RRs and 95% CIs were 0.87 (0.79, 0.95), 0.88 (0.79, 0.99) and 0.90 (0.84, 0.98), respectively. We also found an inverse dose-response relation between the risk of developing hypertension and fruit intake, and total fruit and vegetables consumption. The incident risk of hypertension was decreased by 1.9% for each serving per day of fruit consumption, and decreased by 1.2% for each serving per day of total fruit and vegetables consumption. Our results support the recommendation to increase the consumption of fruit and vegetables with respect to preventing the risk of developing hypertension. However, further large prospective studies and long-term high-quality randomized controlled trials are still needed to confirm the observed association.

This study focused on workaholism as a personal attitude toward work and examined its effects on sleep quality among Japanese employees from various occupations. The present study aimed to demonstrate the prospective association of workaholism (i.e., working excessively hard in a compulsive fashion) with sleep quality among Japanese employees. A Web-based prospective survey was conducted in October 2010 and May 2011 among registered monitors of a survey company. The questionnaire included workaholism, sleep quality, job characteristics, and demographics. Overall, 13,564 monitors were randomly invited to complete the first wave of the survey. The first 2,520 respondents were included in this study. The respondents who completed the first wave were invited to complete the second wave of the survey; 2,061 answered. A total of 364 respondents who changed their working conditions during the follow-up period were excluded. In addition, due to missing values, data from 14 respondents were excluded. Thus, the responses from 1,683 respondents were included in the analysis (859 males and 824 females). An analysis of covariance (ANCOVA) was conducted to compare adjusted sleep quality at follow-up among workaholism groups (low, middle, and high). To conduct the ANCOVA, we adjusted for demographics, sleep quality at baseline, and job characteristics. The high-workaholic group had significantly longer sleep latency at follow-up compared with the low- and middle-workaholic groups after adjusting for demographics, sleep latency at baseline, and job characteristics. In addition, the high-workaholic group demonstrated significantly higher levels of daytime dysfunction compared with the low-workaholic group. However, no significant differences were found among workaholic groups in terms of overall sleep quality, sleep duration, habitual sleep efficiency, sleep disturbance, and use of sleep medication. Workaholism was associated with poor sleep quality at the 7-month follow-up in terms of sleep latency and daytime dysfunction.

We are revising the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital-related costs of acute care hospitals to implement changes arising from our continuing experience with these systems and to implement certain statutory provisions contained in the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively known as the Affordable Care Act) and other legislation. We also are setting forth the update to the rate-of-increase limits for certain hospitals excluded from the IPPS that are paid on a reasonable cost basis subject to these limits. We are updating the payment policy and the annual payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs) and implementing certain statutory changes made by the Affordable Care Act. In addition, we are finalizing an interim final rule with comment period that implements section 203 of the Medicare and Medicaid Extenders Act of 2010 relating to the treatment of teaching hospitals that are members of the same Medicare graduate medical education affiliated groups for the purpose of determining possible full-time equivalent (FTE) resident cap reductions.

Despite the profound evolution in the safety and efficacy of neonatal and pediatric anesthesia, questions remain concerning the long-term neurotoxic and neurocognitive effects of the drugs used in anesthetic care. A variety of prospective animal models and retrospective human studies exist that inconsistently demonstrate a detrimental effect of early life exposure to anesthetic drugs and subsequent learning performance. Limitations associated with both non-human and human observational studies are critiqued. Research currently underway is briefly described. A framework for discussing the relevant issues with concerned parents is presented.

To determine the incidence and outcomes of respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (ALRI) including morbidity, nosocomial infection and mortality among newborn infants who were admitted to the neonatal intensive care units (NICUs). A multicenter, prospective study was conducted in newborns who were hospitalized with community acquired or nosocomial RSV infection in 44 NICUs throughout Turkey. Newborns with ALRI were screened for RSV infection by Respi-Strip®-test. Main outcome measures were the incidence of RSV-associated admissions in the NICUs and morbidity, mortality and epidemics results related to these admissions. The incidence of RSV infection was 1.24% (n: 250) and RSV infection constituted 19.6% of all ALRI hospitalizations, 226 newborns (90.4%) had community-acquired whereas 24 (9.6%) patients had nosocomial RSV infection in the NICUs. Of the 250 newborns, 171 (68.4%) were full-term infants, 183 (73.2%) had a BW >2500 g. RSV-related mortality rate was 1.2%. Four NICUs reported seven outbreaks on different months, which could be eliminated by palivizumab prophylaxis in one NICU. RSV-associated ALRI both in preterm and term infants accounts an important percent of hospitalizations in the season, and may threat other high-risk patients in the NICU.

Right lobe living donor liver transplantation is an effective treatment for selected individuals with end-stage liver disease. Although 1 year donor morbidity and mortality have been reported, little is known about outcomes beyond 1 year. Our objective was to analyze the outcomes of the first 202 consecutive donors performed at our center with a minimum follow-up of 12 months (range 12-96 months). All physical complications were prospectively recorded and categorized according to the modified Clavien classification system. Donors were seen by a dedicated family physician at 2 weeks, 1, 3 and 12 months postoperatively and yearly thereafter. The cohort included 108 males and 94 females (mean age 37.3 +/- 11.5 years). Donor survival was 100%. A total of 39.6% of donors experienced a medical complication during the first year after surgery (21 Grade 1, 27 Grade 2, 32 Grade 3). After 1 year, three donors experienced a medical complication (1 Grade 1, 1 Grade 2, 1 Grade 3). All donors returned to predonation employment or studies although four donors (2%) experienced a psychiatric complication. This prospective study suggests that living liver donation can be performed safely without any serious late medical complications and suggests that long-term follow-up may contribute to favorable donor outcomes.

The aim of this prospective, randomized and crossover study was to assess the role of a relatively new mode of mechanical ventilation, biphasic intermittent positive airway pressure (BIPAP) in comparison to another well established one, pressure-support ventilation (PSV) in surgical intensive care patients. 24 generally stable patients, breathing on their own after short-term (< 24 hours) postoperative controlled mechanical ventilation (CMV) were randomized to start on either PSV or BIPAP, and indirect calorimetry measurements were performed after 1 hour adaptation period at two time intervals; immediately after the investigated ventilatory mode was started and 1 hour later. Statistics included a two-tailed paired t-test to compare the two sets of different data, p < 0.5 was considered significant. Oxygen consumption (VO2), energy expenditure (EE), Carbon dioxide production (VCO2), and respiratory quotient (RQ) did not differ significantly between the two groups. There were also no significant differences regarding respiratory rate (RR), minute volume (MV) and arterial blood gas analysis (ABGs). Both modes of ventilation were well tolerated by all patients. PSV and BIPAP can be used for weaning patients comfortably in surgical intensive care after short-term postoperative ventilation. BIPAP may have the credit of being smoother than PSV where no patient effort is required.

Snoring and obstructive sleep apnoea (OSA) are disorders within a wide spectrum of sleep-related breathing disorders (SRBD). Given the obesity epidemic, these conditions will become increasingly prevalent and continue to serve as a large economic burden. A thorough clinical evaluation and appropriate investigations will allow stratification of patients into appropriate treatment groups. A multidisciplinary team is required to manage these patients. Patient selection is critical in ensuring successful surgical and non-surgical outcomes. A wide range of options are available and further long term prospective studies, with standardised data capture and outcome goals, are required to evaluate the most appropriate techniques and long term success rates.

Background We previously reported on the overall incidence, management and outcomes in infants with cardiovascular insufficiency (CVI). However, there are limited data on the relationship of the specific different definitions of CVI to short term outcomes in term and late preterm newborn infants. Objective To evaluate how 4 definitions of CVI relate to short term outcomes and death. Study Design The previously reported study was a multicenter, prospective cohort study of 647 infants ≥ 34 weeks gestation admitted to a Neonatal Research Network (NRN) newborn intensive care unit (NICU) and mechanically ventilated (MV) during their first 72 hours. The relationship of five short term outcomes at discharge and 4 different definitions of CVI were further analyzed. Results All 4 definitions were associated with greater number of days on MV & days on O2. The definition using a threshold blood pressure (BP) measurement alone was not associated with days to full feeding, days in the NICU or death. The definition based on treatment of CVI was associated with all outcomes including death. Conclusions The definition using a threshold BP alone was not consistently associated with adverse short term outcomes. Using only a threshold BP to determine therapy may not improve outcomes.

The purpose of this study was to assess the feasibility and effectiveness of live telemedicine applications in hearing amplification and cochlear implantation. A systematic search was performed in PubMed, MEDLINE, PsychINFO, CINALH, and Web of Science to identify peer-reviewed research. Inclusion criteria were titles containing words from the search terms 1) audiology, otolaryngology, and hearing impairment, 2) rehabilitative methods, and 3) telemedicine. Exclusion criteria were: 1) non-English articles, and 2) non-original research. Twelve eligible studies were identified. The studies employed a prospective design in nine of the articles and retrospective case series in three. The use of telemedicine for the provision of cochlear implant services was examined in eight of the articles and with hearing aids in four of the articles. The types of services include intraoperative cochlear implant telemetry; implant programming and assessment of electrode-specific measures and speech recognition after implantation. Hearing aid programming and remote gain assessments were also reported. Many studies assess patient and provider satisfaction along with encounter time comparison. The studies occurred from 2009 to 2014 and took place in seven countries. This review examined the feasibility of remote telemedicine connection to provide in auditory rehabilitation services through hearing aids and cochlear implants. There are significant concerns regarding Internet bandwidth limitations for remote clinics. There is a paucity of research examining reimbursement and cost-effectiveness for services. Further prospective research investigating cost-effectiveness and bandwidth limitations is warranted to assess long-term sustainability of remote audiological rehabilitative service delivery.

To review the predictive/risk psychological factors at baseline that are associated with a favourable (or non-favourable) outcome following lumbar spinal fusion (LSF). A computer-assisted literature search of PubMed, CINAHL complete and EMBASE for studies published between January 1, 1990 and October 1, 2014 with controlled vocabulary and key words related to LSF, degenerative lumbar spine diagnoses and appropriate terms for predictive variables. Each study was required to be a retrospective or prospective design that involved LSF (all forms). Quality assessment was conducted with the Quality In Prognosis Studies tool. A study protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO# CRD42014008728). The majority of the eight accepted studies were observational, prospective cohorts (n = 6). High levels of baseline depression and lower SF-36 Mental Component Scores (MCS) lower quality of life were associated with non-favourable outcomes. Two studies were rated as high quality, five were moderate and one study had low quality. At present, there are a number of psychological variables that are associated with a poorer outcome with LSF. Higher levels of depression and lower scores on the SF-36 MCS are the most commonly implicated. However, based on the results of the studies using single arm designs there is not enough evidence to determine which psychological variables are influential in predicting outcomes for LSF.

At present, bariatric surgery is the most effective treatment for morbid obesity. Several factors appear to influence the patient's ability to adjust to the postoperative condition, but reliable predictors are lacking. The aim of this study was to assess whether psychological presurgical variables can predict outcome of vertical banded gastroplasty (VBG) in the short term. 38 severely obese patients (6 men and 32 women) underwent laparoscopic VBG. All were assessed prospectively at TO (before surgery) and at T6 (6 months after surgery) with a semi-structured interview and a battery of psychological tests: State Trait Anger Expression Inventory (STAXI), Eating Disorder Inventory (EDI-2), Symptom Checklist 90 (SCL-90), Beck Depression Inventory (BDI), Binge Eating Scale (BES), Body Shape Questionnaire (BSQ), and (only at TO) the Temperament and Character Inventory (TCI). The comparison between TO and T6 found a significant weight loss and an improvement in several dimensions of EDI-2, BDI, and BSQ, together with an increase in the frequency of vomiting. Self-directedness (TCI) and Body Dissatisfaction (EDI-2) appear to be predictors of short-term outcome regarding weight loss. Self-transcendence (TCI) is associated with emerging side-effects. Although larger and longer studies are necessary to confirm these data, Self directedness and Self trascendence emerge as predictors of 6 months clinical and psychological outcome of VBG.

Background: Body weight increases with aging. Short-term,longitudinal exercise training studies suggest that increasing exerciseproduces acute weight loss, but it is not clear if the maintenance oflong-term, vigorous exercise attenuates age-related weight gain inproportion to the exercise dose. Methods: Prospective study of 6,119 maleand 2,221 female runners whose running distance changed less than 5 km/wkbetween their baseline and follow-up survey 7 years later. Results: Onaverage, men who ran modest (0-24 km/wk), intermediate (24-48 km/wk) orprolonged distances (>_48 km/wk) all gained weight throughage 64,however, those who ran ?48 km/wk had one-half the average annual weightgain of those who ran<24 km/wk. Age-related weightmore » gain, and itsreduction by running, were both greater in younger than older men. Incontrast, men s gain in waist circumference with age, and its reductionby running, were the same in older and younger men. Women increased theirbody weight and waist and hip circumferences over time, regardless ofage, which was also reduced in proportion to running distance. In bothsexes, running did not attenuate weight gain uniformly, but ratherdisproportionately prevented more extreme increases. Conclusion: Men andwomen who remain vigorously active gain less weight as they age and thereduction is in proportion to the exercise dose.« less

Specific components of dairy, such as whey proteins may have beneficial effects on body composition by suppressing appetite, although the findings of existing studies have been inconsistent. Therefore, a meta-analysis of randomized controlled trials was performed to investigate effect of whey protein supplementation on long and short term appetite. A systematic search was conducted to identify eligible publications. Means and SDs for hunger, fullness, satiety, desire to eat and prospective consumption of food, before and after intervention, were extracted and then composite appetite score (CAS) calculated. To pool data, either a fixed-effects model or a random-effects model and for assessing heterogeneity, Cochran's Q and I 2 tests were used. Eight publications met inclusion criteria that 5 records were on short term and 3 records on long term appetite. The meta-analysis showed a significant reduction in long term appetite by 4.13 mm in combined appetite score (CAS) (95% Confidence interval (CI): -6.57, -1.96; p = 0.001). No significant reduction in short term appetite was also seen (Mean difference (MD) = -0.39 95% CI = -2.07, 1.30; p = 0.653). Subgroup analyses by time showed that compared with carbohydrate, the reduction in appetite following consumption of whey consumption was not significant (MD = -0.39, 95% CI = -2.07, 1.3, p = 0.65, I 2  = 0.0%.)A significant reduction in prospective food consumption was seen (MD = -2.17, 95% CI = -3.86, -0.48). The results of our meta-analysis showed that whey protein may reduce the long and short term appetite, but our finding did not show any significant difference in appetite reduction between whey protein and carbohydrate in short duration.

Seizures are common in dogs and can be caused by non-epileptic conditions or epilepsy. The clinical course of newly diagnosed epilepsy is sparsely documented. The objective of this study was to prospectively investigate causes for seizures (epileptic and non-epileptic) in a cohort of dogs with new-onset untreated seizures, and for those dogs with newly diagnosed epilepsy to investigate epilepsy type, seizure type and the course of disease over time, including the risk of seizure recurrence. Untreated client-owned dogs experiencing new-onset seizures were prospectively enrolled in a longitudinal observational study including clinical investigations and long-term monitoring at the Copenhagen University Hospital for Companion Animals. A baseline clinical assessment was followed by investigator/owner contact every eight weeks from inclusion to death or end of study. Inclusion of dogs was conducted from November 2010 to September 2012, and the study terminated in June 2014. One hundred and six dogs were included in the study. Seventy-nine dogs (74.5%) were diagnosed with epilepsy: 61 dogs (77.2%) with idiopathic epilepsy, 13 dogs (16.5%) with structural epilepsy and five dogs (6.3%) with suspected structural epilepsy. A non-epileptic cause for seizures was identified in 13 dogs and suspected in 10 dogs. Four dogs in which no cause for seizures was identified experienced only one seizure during the study. In dogs with idiopathic epilepsy 60% had their second epileptic seizure within three months of seizure onset. Twenty-six dogs with idiopathic epilepsy (43%) completed the study without receiving antiepileptic treatment. The natural course of idiopathic epilepsy (uninfluenced by drugs) was illustrated by highly individual and fluctuating seizure patterns, including long periods of remission. Cluster seizures motivated early treatment. In a few dogs with a high seizure frequency owners declined treatment against the investigators advice. Epilepsy is the most likely diagnosis in dogs presenting with new-onset seizures. The course of idiopathic epilepsy is highly individual and might not necessarily require long-term treatment. This must be considered when advising owners about what to expect with regard to treatment and prognosis.

To compare long-term outcome of children and young adults with arterial ischemic stroke (AIS) from 2 large registries. Prospective cohort study comparing functional and psychosocial long-term outcome (≥2 years after AIS) in patients who had AIS during childhood (1 month-16 years) or young adulthood (16.1-45 years) between January 2000 and December 2008, who consented to follow-up. Data of children were collected prospectively in the Swiss Neuropediatric Stroke Registry, young adults in the Bernese stroke database. Follow-up information was available in 95/116 children and 154/187 young adults. Median follow-up of survivors was 6.9 years (interquartile range 4.7-9.4) and did not differ between the groups (p = 0.122). Long-term functional outcome was similar (p = 0.896): 53 (56%) children and 84 (55%) young adults had a favorable outcome (modified Rankin Scale 0-1). Mortality in children was 14% (13/95) and in young adults 7% (11/154) (p = 0.121) and recurrence rate did not differ (p = 0.759). Overall psychosocial impairment and quality of life did not differ, except for more behavioral problems among children (13% vs 5%, p = 0.040) and more frequent reports of an impact of AIS on everyday life among adults (27% vs 64%, p < 0.001). In a multivariate regression analysis, low Pediatric NIH Stroke Scale/NIH Stroke Scale score was the most important predictor of favorable outcome (p < 0.001). There were no major differences in long-term outcome after AIS in children and young adults for mortality, disability, quality of life, psychological, or social variables. © 2015 American Academy of Neurology.

2017-01-01

ABSTRACT Purpose There is increasing interest in fitting children with soft contact lenses. This review collates data from a range of studies to estimate the incidence of complications, specifically corneal infiltrative events and microbial keratitis, in patients under the age of 18 years. Methods Peer-review papers were identified using PubMed and the Web of Science. A broad range of studies are summarized including large-scale epidemiological studies of contact lens–related complications, hospital-based case series, long- and short-term prospective studies, and multicenter retrospective studies. Results Nine prospective studies representing 1800 patient years of wear in 7- to 19-year-olds include safety outcomes. In three large prospective studies representing between 159 and 723 patient years of soft contact lens wear in patients 8 to 14 years, the incidence of corneal infiltrative events is up to 136 per 10,000 years. Data from a large retrospective study show similar rates of corneal infiltrative events: 97 per 10,000 years in 8- to 12-year-olds (based on 411 patient years of wear) and 335 per 10,000 years in 13- to 17-year-olds (based on 1372 patient years of wear). None of the prospective studies report any cases of microbial keratitis. Five clinical studies where safety data are not reported constitute a further 493 patient years. One retrospective study found no cases of microbial keratitis occurred in 8- to 12-year-olds (411 patient years) and an incidence of 15 per 10,000 patient years in 13- to 17-year-olds (1372 patient years)—no higher than the incidence of microbial keratitis in adults wearing soft contact lenses on an overnight basis. Conclusions The overall picture is that the incidence of corneal infiltrative events in children is no higher than in adults, and in the youngest age range of 8 to 11 years, it may be markedly lower.

The study of those who have sustained traumatic brain injuries (TBI) during military conflicts has greatly facilitated research in the fields of neuropsychology, neurosurgery, psychiatry, neurology, and neuroimaging. The Vietnam Head Injury Study (VHIS) is a prospective, long-term follow-up study of a cohort of 1,221 Vietnam veterans with mostly penetrating brain injuries, which has stretched over more than 40 years. The scope of this study, both in terms of the types of injury and fields of examination, has been extremely broad. It has been instrumental in extending the field of TBI research and in exposing pressing medical and social issues that affect those who suffer such injuries. This review summarizes the history of conflict-related TBI research and the VHIS to date, as well as the vast range of important findings the VHIS has established. PMID:21625624

2014-10-01

The objective of this study was to compare the early migration of the cruciate retaining and posterior stabilising versions of the recently introduced Triathlon™ total knee system, with a view to predicting long term fixation performance. Sixty patients were prospectively randomised to receive either Triathlon™ posterior stabilised cemented knee prosthesis or Triathlon™ cruciate retaining cemented knee prosthesis. Tibial component migration was measured by radiostereometric analysis postoperatively and at three months, one year and two years. Clinical outcome was measured by the American Knee Society Score and Knee Osteoarthritis and Injury Outcome Score. There were no differences in rotation around the three coordinal axes or in the maximum total point motion (MTPM) during the two year follow-up. The posterior stabilised prosthesis had more posterior-anterior translation at three months and one year and more caudal-cranial translation at one year and two years. There were no differences in functional outcome between the groups. The tibial tray of the Triathlon™ cemented knee prosthesis showed similar early stability. Level I. Article focus: This was a prospective randomised trial aiming to compare the single radius posterior stabilised (PS) Triathlon™ total knee arthroplasty (TKA) to the cruciate retaining Triathlon™ TKA system with regard to fixation. Strengths and limitations of this study: Strength of this study was that it is a randomised prospective trial using an objective measuring tool. The sample size of 25-30 patients was reportedly sufficient for the screening of implants using RSA [1]. ClinicalTrials.gov Identifier: NCT00436982. Copyright © 2014 Elsevier B.V.

Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high-quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications. We conducted a comprehensive search in the MEDLINE, EMBASE, and Cochrane library databases. Only retrospective or prospective comparative studies were included in this meta-analysis. The literature search, data extraction, and quality assessment were conducted by two independent reviewers. The primary outcomes were clinical scores and patient satisfaction. We also investigated the prevalence of complications and the re-operation rate. Ten comparative studies were included (four prospective and six retrospective studies). There were no significant differences between the two procedures in the American Orthopaedic Foot and Ankle Society ankle-hindfoot score, Short Form-36 physical component summary and mental component summary scores, visual analogue scale for pain, and patient satisfaction rate. The risk of re-operation and major surgical complications were significantly increased in the TAA group. The meta-analysis revealed that TAA and AA could achieve similar clinical outcomes, whereas the incidence of re-operation and major surgical complication was significantly increased in TAA. Further studies of high methodological quality with long-term follow-up are required to confirm our conclusions.

Explicit and implicit cognition: a preliminary test of a dual-process theory of cognitive vulnerability to depression.

2007-06-01

Two studies were conducted to test a dual-process theory of cognitive vulnerability to depression. According to this theory, implicit and explicit cognitive processes have differential effects on depressive reactions to stressful life events. Implicit processes are hypothesized to be critical in determining an individual's immediate affective reaction to stress whereas explicit cognitions are thought to be more involved in long-term depressive reactions. Consistent with hypotheses, the results of study 1 (cross-sectional; N=237) showed that implicit, but not explicit, cognitions predicted immediate affective reactions to a lab stressor. Study 2 (longitudinal; N=251) also supported the dual-process model of cognitive vulnerability to depression. Results showed that both the implicit and explicit measures interacted with life stress to predict prospective changes in depressive symptoms, respectively. However, when both implicit and explicit predictors were entered into a regression equation simultaneously, only the explicit measure interacted with stress to remain a unique predictor of depressive symptoms over the five-week prospective interval.

Adverse health effects of high-effort/low-reward conditions.

PubMed

Siegrist, J

1996-01-01

In addition to the person-environment fit model (J. R. French, R. D. Caplan, & R. V. Harrison, 1982) and the demand-control model (R. A. Karasek & T. Theorell, 1990), a third theoretical concept is proposed to assess adverse health effects of stressful experience at work: the effort-reward imbalance model. The focus of this model is on reciprocity of exchange in occupational life where high-cost/low-gain conditions are considered particularly stressful. Variables measuring low reward in terms of low status control (e.g., lack of promotion prospects, job insecurity) in association with high extrinsic (e.g., work pressure) or intrinsic (personal coping pattern, e.g., high need for control) effort independently predict new cardiovascular events in a prospective study on blue-collar men. Furthermore, these variables partly explain prevalence of cardiovascular risk factors (hypertension, atherogenic lipids) in 2 independent studies. Studying adverse health effects of high-effort/low-reward conditions seems well justified, especially in view of recent developments of the labor market.

Can ACTH therapy improve the long-term outcome of drug-resistant frontal lobe epilepsy?

Gobbi, Giuseppe; Loiacono, Giulia; Boni, Antonella; Marangio, Lucia; Verrotti, Alberto

2014-06-01

Frontal lobe epilepsy is a common focal epilepsy in children and is often difficult to treat. Adrenocorticotropic hormone (ACTH) or steroids have been used for patients with several forms of medically intractable epilepsy. We evaluated the short, medium, and long-term evolution of patients with frontal lobe epilepsy and secondary bilateral synchrony on the EEG, who received ACTH treatment. Patients were recruited for an add-on trial during clinical practice, and data was retrospectively analysed. The study group comprised 6 patients treated with ACTH. The effects of ACTH were assessed in the short term (at the end of a 6-week period of ACTH treatment), medium term (at 6 months after the end of treatment), and long term (at 12 months after the end of treatment). At short-term follow-up, ACTH treatment was effective for all types of seizures in 5 of 6 patients and ineffective in 1 patient. All patients who were seizure-free at the end of ACTH treatment maintained an excellent outcome, remaining seizure-free at the end of follow-up. Our study demonstrates that ACTH may represent an effective treatment for frontal lobe epilepsy with secondary bilateral synchrony. Further double-blind prospective studies are required to confirm our initial findings.

Some current views on the origins and prospects of correlation optics.

2016-04-20

The state of the art modern branch of optics and photonics now referred to as correlation optics is discussed in connection with both its origins and promising prospects. We use here the term "correlation" not only as a synonym of the term "coherence," but also for emphasizing the necessity of taking into account fine, sometimes enigmatic, phase relations among the components of complex optical fields, even if such fields are conventionally defined as completely coherent. Selection of topics for this brief review of correlation optics outlooks was not dictated by intention of comprehensive representation of this field of research, but rather by the scientific interests of the authors, ranging from classical theory of diffraction, holography, and light-scattering to modern singular optics.
