Objective

The effect of physical activity on musculoskeletal health in older adults is not completely understood. The aim of this study was to determine the relationship between physical activity and 5-year changes in physical performance tests and bone mineral density (BMD) in postmenopausal women.

Study design

The design was a 5-year cohort study.

Main outcome measures

Subjects were 507 women (55-74 years old) living in a rural community in Japan. Physical activity assessed included housework, farm work, and moderate leisure-time physical activity within the previous week. Measurements at baseline included handgrip strength, walking time (timed “Up & Go” test) and BMD of the femoral neck and vertebrae. Five-year changes in these measures (outcome variables) were compared among groups with different levels of physical activity by analysis of covariance.

Results

Women who did not do housework performed worse in changes in handgrip strength (difference = 2.22 kg, P = 0.0201) and worse in changes in the walking time (difference = 0.54 s, P = 0.0072) than those who did housework alone. Women who spent at least 9 h per week (median = 24) doing farm work performed better in changes in handgrip strength (difference = 0.28 kg, P = 0.0334), but worse in changes in the walking time (difference = 0.66 s, P < 0.0001) than those who did not do farm work. However, leisure-time activity was not associated with changes in any outcome variable, and none of the physical activities predicted BMD changes.

Conclusions

Engaging in housework and farm work are determinants of physical function in postmenopausal women, which may help them maintain independence in daily living.  相似文献

Background

Few studies have examined differences in emotional responding among distinct types of positive stimuli. This is important to understand both for individuals characterized by extreme positive mood (i.e., bipolar disorder) and healthy adults.

Methods

Using a multi-method within-subjects design, the current study examined physiological, behavioral, and self-reported responses to normative (film) and idiographic (memory) happy stimuli in bipolar (BD; n = 25) and healthy control groups (CTL; n = 23).

Results

For both groups, the happy films were associated with greater self-reported and behavioral displays of positive emotion compared to the happy memory. Furthermore, the BD group displayed greater cardiac vagal tone - a putative marker of positive emotion - across both the film and memory.

Conclusion

Normative stimuli were more potent elicitors of positive emotion compared to idiographic stimuli. The study provided further evidence for cardiac vagal tone as a potential biomarker of extreme positive emotion in BD.  相似文献

Objective

Evidence suggests that physicians’ use of motivational interviewing (MI) techniques helps patients lose weight. We assessed patient, physician, relationship, and systems predictors of length of weight-loss discussions and whether physicians’ used MI techniques.

Methods

Forty primary care physicians and 461 of their overweight or obese patients were audio recorded and surveyed.

Results

Weight-related topics were commonly discussed (nutrition 78%, physical activity 82%, and BMI/weight 72%). Use of MI techniques was low. A multivariable linear mixed model was fit to time spent discussing weight, adjusting for patient clustering within physician. More time was spent with obese patients (p = .0002), by African American physicians (p = .03), family physicians (p = .02), and physicians who believed patients were embarrassed to discuss weight (p = .05). Female physicians were more likely to use MI techniques (p = .02); African American physicians were more likely to use MI-inconsistent techniques (p < .001).

Conclusion

Primary care physicians routinely counsel about weight and are likely to spend more time with obese than with overweight patients. Internists spend less time on weight. Patient and systems factors do not seem to influence physicians’ use MI techniques.

Practice implications

All physicians, particularly, male and African American physicians, could increase their use of MI techniques to promote more weight loss among patients.  相似文献

Introduction

Bacteriological testing is aimed to reduce the risk of transmission of infections. However, the detection of Bacteria by culture requires from 18 hours to 14 days and may produce erroneous results for fastidious species. The goal of this work was to design and validate a new tool for bacterial testing.

Methods

The test is based on the fast real-time PCR (frt PCR). The DNA extracted from samples containing internal controls are introduced into four tubes containing primers and probes for the frt PCR. The cycling program consists in 1 × at 95 °C for 10 min and 45 × (15 s at 95 °C, 8 s) at 52 °C and 10 s at 72 °C.

Results

The frt PCR detects 0,01 CFU/μl of Bacteria and identifies eight Genera without interferences from the environment or from fungi and with no need for melting curve analysis or additional sequencing.

Discussion

The frt PCR detects and quantifies Bacteria identifying and assessing the load of Staphylococci, Streptococci, Haemophilus, Pseudomonas, Enterobacteria, Acinetobacter, Propionibacteriacae and Corynebacteria.

Conclusion

Cultures require at least 24 hours but the new frt PCR reduces the time to 90 minutes. Larger series of samples are necessary to confirm the usefulness of this new test for routine bacterial sterility controls.  相似文献

Objective

Our study goal was to assess the effects of a brief patient video on breast cancer knowledge and attitudes among Latina women at a community health center.

Methods

We conducted pre- and post-testing of knowledge and attitudes in women aged 40 years or older with active screening referrals (n = 91). We compared pre- and post-test knowledge and attitudes overall and by baseline values.

Results

Mean knowledge increased from 5.8/10 to 6.9/10 (p < 0.05), with the greatest increases in those with low baseline knowledge (p < .001). There were no changes in mean attitudes, which were high at baseline (3.8/5); however, among the 16 women with negative/neutral attitudes, 50% developed positive attitudes after watching the video (p < 0.05). Baseline intention to complete screening was high at 98%.

Conclusion

Although the overall effects were modest, the greatest improvements were in those with low baseline knowledge scores and negative/neutral baseline attitudes. Future testing should examine the effects in a community-based sample.

Practice implications

A brief patient video has promise for influencing patient knowledge and perhaps attitudes while being amenable to integration into clinical flow.  相似文献

Objectives

To develop and test a framework for evaluating the consultation skills of practitioners undertaking medication-related consultations.

Methods

Key components of medication-related consultations were identified through a literature review and compiled to form an initial consultation skills framework. This was iteratively refined through consultation with experts (n = 21) to form the Medication-Related Consultation Framework (MRCF). Psychometric testing was undertaken by analyzing pharmacists’ (n = 10) assessment of fifteen pre-recorded simulated consultations.

Results

The MRCF consisted of 46 consultation behaviors, grouped into five sections. Performance was rated at individual behavior, framework section and global consultation levels. The MRCF discriminated between good, satisfactory and poor consultations at the global rating level (p < 0.01) with good test-retest reliability (rho = 0.59-0.95) and moderate inter-assessor reliability (Kendall's W = 0.67). There was also good internal consistency for the five sections (Cronbach's alphas = 0.58-0.97).

Conclusions

The MRCF demonstrated good psychometric properties at the global and section rating levels. Some inconsistencies in assessors’ ratings of individual consultation behaviors were indentified, which may represent a future training need.

Practice implications

The MRCF provides healthcare professionals with a patient-centered consultation structure, serving to identify medication-related needs and potentially support adherence. It also allows the quality of a practitioner's consultation to be evaluated.  相似文献

Objective

This study aimed to develop and pilot test an online screening decision aid (DA) for men with a family history of prostate cancer.

Methods

Eligible men (with no previous prostate cancer diagnosis) were recruited through relatives attending a urology outpatient clinic. Men evaluated the DA in two stages. First, they appraised a paper-based version using a questionnaire (n = 22). Second, the same men were asked to reflect on an interactive web-based version via a semi-structured telephone interview (n = 20).

Results

Men evaluated both forms of the DA positively. Of the paper-based version, the majority of participants found the DA useful (91%), and that it contained enough information to make a screening decision (73%). All participants reported that the online DA was easy to use and navigate. Most participants reported that a website was their preferred mode of receiving prostate cancer screening information (70%).

Conclusion

The developed DA may represent the first online decision-making tool designed specifically for men with a family history prostate cancer that presents age and risk specific information to the user.

Practice implications

Comprehensive evaluations of the efficacy and impact of educational interventions such as this are crucial to improve services for individuals making informed screening decisions.  相似文献

Background

It is unknown to what extent the human coronaviruses (HCoVs) OC43, HKU1, 229E and NL63 infect healthy children. Frequencies of infections are only known for hospitalized children.

Objectives

Comparing infection frequencies in children who have mild infections with frequencies in children needing hospital uptake will determine whether infection by one of the four HCoVs leads to more severe disease. In addition, the sequence of seroconversions can reveal whether infection by one HCoV protects from infection by other HCoVs.

Study design

Two distinct study groups were monitored: healthy children and children hospitalized due to respiratory infection. HCoV natural infection rates in healthy children were obtained by serology in 25 newborns (followed 0-20 months). The frequencies of severe HCoVs infection was determined by real time RT-PCR among 1471 hospitalized infants (<2-years old) with acute respiratory tract disease.

Results

The majority of healthy children seroconverted for HCoV-OC43 (n = 19) and HCoV-NL63 (n = 17), less for HCoV-HKU1 (n = 9) and HCoV-229E (n = 5). Notably, HCoV-HKU1 seroconversion was absent after HCoV-OC43 infection. Also HCoV-229E infection was rarely observed after HCoV-NL63 infection (1 out of 5). In the hospital 207 (14%) out of 1471 children were HCoV positive. Again we observed most infection by HCoV-OC43 (n = 85) and HCoV-NL63 (n = 60), followed by HCoV-HKU1 (n = 47) and HCoV-229E (n = 15).

Conclusions

HCoV-NL63 and HCoV-OC43 infections occur frequently in early childhood, more often than HCoV-HKU1 or HCoV-229E infections. HCoV-OC43 and HCoV-NL63 may elicit immunity that protects from subsequent HCoV-HKU1 and HCoV-229E infection, respectively, which would explain why HCoV-OC43 and HCoV-NL63 are the most frequently infecting HCoVs. There are no indications that infection by one of the HCoVs is more pathogenic than others.  相似文献

Objective

The modern joint protection (JP) concept for people with rheumatoid arthritis (RA) is an active coping strategy to improve daily tasks and role performance by changing working methods and using assistive devices. Effective group JP education includes psycho-educational interventions. The Pictorial Representation of Illness and Self Measure (PRISM) is an interactive hands-on-tool, assessing (a) the individual's perceived burden of illness and (b) relevant individual resources. Both issues are important for intrinsic motivation to take action and change behaviour. This study compared individual conventional JP education (C-JP) with PRISM-based JP education (PRISM-JP).

Methods

An assessor-blinded multicentre randomized controlled trial, including four JP education sessions over 3 weeks, with assessments at baseline and 3 months.

Results

In total 53 RA patients participated. At 3 months, the PRISM-JP (n = 26) participants did significantly better compared to the C-JP participants (n = 27) in JP behaviour (p = 0.02 and p = 0.008 when corrected for baseline values), Arthritis Self-efficacy (ASES, p = 0.015) and JP self-efficacy (JP-SES, p = 0.047). Within-group analysis also showed less hand pain (p < 0.001) in PRISM-JP group.

Conclusion

PRISM-JP more effectively supported learning of JP methods, with meaningful occupations, resource activation and self-efficacy acting as important mediators.

Practice implications

PRISM improved patient-clinician communication and is feasible for occupational therapy.  相似文献

Background

Correlation between hepatic HCV-RNA and serum HCV-RNA, severity of liver disease and response to therapy is poorly known.

Objectives

To assess the influence of hepatic HCV-RNA level on severity of liver disease and response to therapy in a large cohort of chronic hepatitis C (CHC) patients.

Study Design

HCV-RNA was measured in frozen liver biopsies and serum samples from 130 CHC patients the day of liver biopsy prior to treatment. Liver fibrosis was assessed by Ishaq scoring. A Sustained Virological Response (SVR) was observed in 52% of the patients, non-response (NR) in 34%.

Results

Mean ± standard deviation hepatic HCV-RNA level was 7.69 ± 0.67 log10 copies/mg of liver. Mean serum HCV-RNA level was 6.21 ± 0.72 log10 copies/ml. There was a correlation between hepatic and serum HCV-RNA in genotype 1 and 4 (p = 0.008 and p = 0.03) and age (p = 0.006). Mean hepatic HCV-RNA was 7.70 ± 0.69 vs 7.67 ± 0.68 log10 copies/mg of liver, in patients with significant fibrosis vs those with mild fibrosis, respectively (p = 0.7); 8.04 ± 0.68; 7.44 ± 0.47; 7.43 ± 0.49 and 7.44 ± 0.71 log10 copies/mg of liver in genotypes 1, 2, 3 and 4, respectively (p = 0.0001); higher in women than in men (p = 0.04); 7.60 ± 0.63, 7.71 ± 0.54 and 7.96 ± 0.73 log10 copies/mg in SVR, relapsers and NR, respectively (p = 0.1). Multivariate analysis showed that high hepatic HCV-RNA level was independently associated with genotype and response to therapy was associated with genotype independently from hepatic HCV-RNA level.

Conclusions

Hepatic HCV-RNA level was not associated with severity of liver disease. High level was strongly associated with HCV genotype independently from response to therapy.  相似文献

Objective

To examine the influence of patient and physician communication factors on diagnostic delay (DD).

Methods

242 patients diagnosed with colorectal cancer (CRC) in the past 6 months who experienced symptoms prior to diagnosis were administered a 2-h semi-structured qualitative interview to assess communication with health care provider and ease of access to care, among other factors. Patient-provided information was verified via review of medical records.

Results

The factors associated with DD > 2 months included lower income (OR = 0.56, p = 0.03), having regular physician prior to receiving a cancer diagnosis (OR = 2.52, p = 0.03), having a physician who used temporizing communication strategies during the consultation (OR = 2.41, p = 0.02), receiving an initial alternate diagnosis (OR = 3.36, p = 0.02), experiencing referral delay (OR = 3.61, p = < 0.001), and experiencing follow-up delay of any kind (OR = 3.32, p = 0.01).

Conclusion

Excellent communication skills that appropriately probe for relevant social and economic patient information, assist patients in distinguishing and elaborating on symptoms, and provide clear rationale and instructions for future steps, will speed along the diagnosis process and could be the difference between early and late stage CRC.

Practice implications

Increased understanding of physician communication and practice styles that contribute to DD could have a positive impact on decreasing the morbidity and mortality from this disease.  相似文献

Objective

To examine the changes in performance on heart failure knowledge assessments administered before and after discharge education.

Methods

We conducted a randomized controlled trial comparing the effects of a 1-h, one-on-one teaching session with a nurse educator to the standard discharge process in patients with systolic heart failure. Patients completed a 30 point heart failure knowledge questionnaire (HFKQ) prior to and 3 months after the education intervention.

Results

Patients randomized to the nurse education intervention (n = 113) demonstrated significantly higher total HFKQ score increases compared to patients receiving the standard discharge process (n = 114) (median, IQR 1, 0 to 4 vs 0, −2 to 2, p = 0.007). Patients experiencing death or rehospitalization in the subsequent 6 months were found to have significantly lower HFKQ scores (10, 7 to 12 vs 11, 8 to 13, p = 0.002) compared to patients without a clinical event.

Conclusion

Heart failure nurse education at the time of hospital discharge results in improved patient knowledge and reduced risk of readmission.

Practice implications

Health care personnel should encourage education sessions for heart failure patients. Resources possibly need to be allocated for nurse led education sessions in heart failure patients as it improves outcomes and knowledge.  相似文献

Objective

The purpose of this study was to develop and evaluate a 12-week weight management intervention involving computerized self-monitoring and technology-assisted feedback with and without an enhanced behavioral component.

Methods

120 overweight (30.5 ± 2.6 kg/m2) adults (45.0 ± 10.3 years) were randomized to one of three groups: computerized self-monitoring with Basic feedback (n = 45), Enhanced behavioral feedback (n = 45), or wait-list control (n = 30). Intervention participants used a computer software program to record dietary and physical activity information. Weekly e-mail feedback was based on computer-generated reports, and participants attended monthly measurement visits.

Results

The Basic and Enhanced groups experienced significant weight reduction (−2.7 ± 3.3 kg and −2.5 ± 3.1 kg) in comparison to the Control group (0.3 ± 2.2; p < 0.05). Waist circumference and systolic blood pressure also decreased in intervention groups compared to Control (p < 0.01).

Conclusions

A program using computerized self-monitoring, technology-assisted feedback, and monthly measurement visits produced significant weight loss after 12 weeks. However, the addition of an enhanced behavioral component did not improve the effectiveness of the program.

Practice implications

This study suggests that healthcare professionals can effectively deliver a weight management intervention using technology-assisted strategies in a format that may complement and reduce face-to-face sessions.  相似文献

Objective

Communication skills represent an essential component of clinical competence. In the field of pediatrics, communication between physicians and patients’ parents is characterized by particular difficulties. To investigate the effects of a parent-physician communication skills training program on OSCE performance and self-efficacy in a group control design.

Methods

Parallel to their daily work in the outpatient department, intervention-group experienced clinicians in practice (n = 14) participated in a communication training with standardized parents. Control-group physicians (n = 14) did not receive any training beyond their daily work. Performance was assessed by independent video ratings of an OSCE. Both groups rated their self-efficacy prior to and following training.

Results

Regarding OSCE performance, the intervention group demonstrated superior skills in building relationships with parents (p < .024) and tended to perform better in exploring parents’ problems (p < .081). The communication training program led to significant improvement in self-efficacy with respect to the specific training objectives in the intervention group (p < .046).

Conclusion

Even in physicians with considerable experience, structured communication training with standardized parents leads to significant improvement in OSCE performance and self-efficacy.

Practise implications

Briefness and tight structure make the presented communication training program applicable even for experienced physicians in daily clinical practice.  相似文献

Background

The hypomanic personality style is a risk factor for bipolar spectrum disorders and shares many cognitive and affective features with the bipolar spectrum. Schema theory may serve as a unifying theory that would explain many of these features. This study is an exploratory investigation of Early Maladaptive Schemas (EMSs) in association with the hypomanic personality and bipolar spectrum risk.

Methods

A sample of 966 participants completed the Young Schema Questionnaire, the Hypomanic Personality Scale and the Patient Health Questionnaire. Associations were investigated using univariate and multivariate analyses. Participants deemed at risk of developing a bipolar disorder (N = 107) were compared to low-risk controls (N = 681).

Results

The Entitlement/Grandiosity and Insufficient Self-Control/Self-Discipline positively predicted the risk of developing a bipolar disorder, while Emotional Inhibition negatively predicted risk. High-risk participants demonstrated higher mean scores on all EMSs except Emotional Inhibition. These three EMSs, combined with Vulnerability to Harm or Illness, significantly predicted group membership.

Conclusions

A bipolar spectrum EMS profile was identified, consisting of Entitlement/Grandiosity, Insufficient Self-Control/Self-Discipline and the absence of Emotional Inhibition. These EMSs are highly consistent with characteristics of the bipolar spectrum. This study supports the application of schema theory to the hypomanic personality and bipolar spectrum. Future research should explore the possible interaction between EMSs, life events and affective symptoms and the applicability of schema therapy to the bipolar spectrum.  相似文献

Background

Both delayed sleep phase syndrome (DSPS) and seasonal affective disorder (SAD) may manifest similar delayed circadian phase problems. However, the relationships and co-morbidity between the two conditions have not been fully studied. The authors examined the comorbidity between DSPS and SAD.

Methods

We recruited a case series of 327 DSPS and 331 controls with normal sleep, roughly matched for age, gender, and ancestry. Both DSPS and controls completed extensive questionnaires about sleep, the morningness-eveningness trait, depression, mania, seasonality of symptoms, etc.

Results

The prevalences of SAD and subsyndromal SAD (S-SAD) were higher in DSPS compared to controls (χ2 = 12.65, p = 0.002). DSPS were 3.3 times more likely to report SAD (odds ratio, 3.34; 95% CI, 1.41-7.93) compared to controls as defined by the Seasonal Pattern Assessment Questionnaire (SPAQ). Correspondingly, DSPS showed significantly higher seasonality scores compared to controls in mood, appetite, and energy level subscores and the global seasonality score (t = 3.12, t = 0.002; t = 2.04, p = 0.041; t = 2.64, p = 0.008; and t = 2.15, p = 0.032, respectively). Weight fluctuation during seasons and winter-summer sleep length differences were also significantly higher in DSPS than controls (t = 5.16, p < 0.001 and t = 2.64, p = 0.009, respectively). SAD and S-SAD reported significantly higher eveningness, higher depression self-ratings, and more previous mania symptoms compared to non-seasonal subjects regardless of whether they were DSPS or controls.

Conclusions

These cases suggested that DSPS is partially comorbid with SAD. These data support the hypothesis that DSPS and SAD may share a pathophysiological mechanism causing delayed circadian phase.  相似文献

Background

Recently a new polyomavirus was identified in a patient with trichodysplasia spinulosa (TS), a rare follicular skin disease of immunocompromised patients characterized by facial spines and overgrowth of inner root sheath cells. Seroepidemiological studies indicate that TSPyV is ubiquitous and latently infects 70% of the healthy individuals.

Objective

To corroborate the relationship between active TSPyV infection and TS disease by analyzing the presence, load, and precise localization of TSPyV infection in TS patients and in controls.

Study design

TS lesional and non-lesional skin samples were retrieved from TS patients through a PubMed search. Samples were analyzed for the presence and load of TSPyV DNA with quantitative PCR, and for expression and localization of viral protein with immunofluorescence. Findings obtained in TS patients (n = 11) were compared to those obtained in healthy controls (n = 249).

Results

TSPyV DNA detection was significantly associated with disease (P < 0.001), with 100% positivity of the lesional and 2% of the control samples. Quantification revealed high TSPyV DNA loads in the lesional samples (∼106 copies/cell), and low viral loads in the occasionally TSPyV-positive non-lesional and control samples (<102 copies/cell). TSPyV VP1 protein expression was detected only in lesional TS samples, restricted to the nuclei of inner root sheath cells over-expressing trichohyalin.

Conclusions

The high prevalence and load of TSPyV DNA only in TS lesions, and the abundant expression of TSPyV protein in the affected hair follicle cells demonstrate a tight relation between TSPyV infection and TS disease, and indicate involvement of active TSPyV infection in TS pathogenesis.  相似文献

Objective

To determine whether beliefs in medicines are associated with forgetfulness and carelessness in taking medications.

Methods

Using a survey research design, baseline data (N = 1220) and follow-up data (N = 1024) were collected through an Internet survey using a convenience sample from Medicare enrollees aged 65 and older and who were Internet users. Logistic regression models were used to determine if patient's beliefs about the necessity of taking prescribed medications and their concern beliefs regarding the potential consequences of taking medications were significant in predicting forgetfulness and carelessness in taking medications.

Results

Concern beliefs in medicines were a significant predictor of forgetfulness and carelessness in taking medications.

Conclusion

If all cases of forgetfulness and carelessness in taking medications are considered as unintentional non-adherence with no reference to the patient's beliefs in medicines; using cue based interventions such as phone reminders or alarms are not likely to reduce non-adherence. There was a strong association between patient belief in medications and non-adherence in older adults who were Medicare enrollees.

Practical implications

It is important that researchers consider the influence that patient medication beliefs have on patient adherence to develop better interventions to reduce non-adherence.  相似文献

Objective

To determine which patient factors contribute to improvements in the ABCs of diabetes following a multi-faceted diabetes care intervention.

Methods

A multi-level, cluster design, randomized controlled trial examined the effectiveness of a Chronic Care Model (CCM) intervention in an underserved community (n = 119).

Results

Improvements in glycemic control were experienced among older subjects (p = 0.02), those with higher scores on the WHO-10 Quality of Well-Being Subscale 1 (p = 0.05), and those in the CCM group (p = 0.04). Insulin use was associated with greater improvements in SBP and DBP. Those taking insulin (p = 0.07), and those more satisfied with their diabetes care and ready to make a behavior change (p = 0.08) experienced larger improvements in Non-HDLc. Medication treatment intensification (TI) did not significantly impact the ABCs.

Conclusion

Psychosocial and sociodemographic factors explained more of the variation in the ABCs than TI, and are important contributors to clinical improvement.

Practice Implications

Providers may be able to identify and intervene on patients who are at risk for developing diabetes complications and improve the consistency, quality, and effectiveness of patient care.  相似文献
