Age-related reference intervals (RIs) of aortic pulse wave velocity (Ao-PWV) obtained from a large healthy population are lacking in South America. The aims of this study were to determine Ao-PWV RIs in a cohort of healthy children and adolescents from Argentina and to generate year-to-year percentile curves.

Ao-PWV was measured in 1000 healthy subjects non-exposed to traditional cardiovascular risk factors (Age: 10–22 y. o., 56% males). First, we evaluated if RIs for males and females were necessaries (correlation and covariate analysis). Second, mean (M) and standard deviation (SD) age-related equations were obtained for cf-PWV, using parametric regression methods based on fractional polynomials. Third, age-specific (year to year) percentiles curves (for all, males and females children and adolescents) were generated using the standard normal distribution. They were, age-specific 1st, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th and 99th percentile curves and values.

After covariate analysis (i.e., adjusting by age, jugulum-symphysis distance, body weight and height), specific RIs for males and females of children and adolescents were evidenced as necessaries. The equations were

For all subjects:

Ao-PWV_Mean = 4.98 + 12.86x10?5 Age3.

Ao-PWV_SD = 0.47 + 21.00x10?6Age3.

For girls:

Ao-PWV_Mean = 5.07 + 10.23x10?5Age3.

Ao-PWV_SD = 0.50 + 10.00x10?6Age3.

For boys:

Ao-PWV_Mean = 4.87 + 15.81x10?5Age3.

Ao-PWV_SD = 0.46 + 22.34x10?6Age3.

Our study provides the largest database to-date concerning Ao-PWV in healthy children and adolescents in Argentina. Age-related equations (M and SD values) for Ao-PWV are reported by the first time. Specific RIs and percentiles of Ao-PWV are now available according to age and sex for an Argentinian population.  相似文献

Objectives: Conceiving narration as a resource to promote older people’s wellbeing, the present work aimed to implement a narrative-based intervention to empower the subjective and psychological wellbeing of older adults living in nursing homes.

Methods: Twenty-one nursing-home residents took part in a narrative training experience consisting of three weekly interview sessions. During each interview, a psychologist helped the participants to construct an autobiographical narrative about their present life in the nursing home based on a Deconstruction-Reconstruction technique. Subjective and psychological wellbeing variables were assessed before and after the intervention.

Results: Subjective but not psychological wellbeing increased over the course of the intervention. The participants reported to appreciate the intervention.

Conclusions: Although preliminary, the results suggest that brief narrative training based on narrative therapy can positively affect nursing-home residents’ subjective wellbeing.

Clinical Implications: Brief narrative interventions implementing deconstruction-reconstruction techniques are feasible for long-term care residents.  相似文献

Objectives: The study aimed to evaluate the effects of an advance care planning (ACP) program on knowledge and attitudes concerning palliative care, and decisions regarding DNR orders in the older residents in a long-term care institution.

Methods: A quasi-experimental design was used. Participants were cognitively unimpaired older residents in a long-term care institution in Taiwan. The experimental group (n = 29) received the intervention including an individual interview using an ACP handbook and a group patient education; whereas the control group (n = 28) received the group patient education only.

Results: There were significant positive effects of the ACP program on understanding of DNR and palliative care, willingness to sign a DNR order, and knowledge of and attitude towards palliative care; however, there was no significant effect on willingness to receive palliative care. Six participants signed the DNR order after the intervention compared to none in the control group.

Conclusions: The ACP program can improve knowledge and attitudes towards palliative care in older residents in long-term care institutions.

Clinical Implications: The ACP program could incorporate multiple components, including individual interview using ACP handbook and group patient education, and address knowledge and attitudes towards palliative care.  相似文献

Background: The co-occurrence of depression and risky alcohol use is clinically relevant given their high rates of comorbidity and reciprocal negative impact on outcomes. Emotion dysregulation is one factor that has been shown to underlie this association. However, literature in this area has been limited in its exclusive focus on emotion dysregulation stemming from negative emotions.

Objectives: The goal of the current study was to extend research by exploring the role of difficulties regulating positive emotions in depression symptom severity, risky alcohol use, and their association.

Methods: Participants were 395 trauma-exposed adults recruited from Amazon’s Mechanical Turk (MTurk) platform (56.20% female, Mage = 35.55) who completed self-report questionnaires.

Results: Zero-order correlations among depression symptom severity, the three subscales of difficulties regulating positive emotions, and risky alcohol use were positive. Two subscales of difficulties regulating positive emotions—nonacceptance of positive emotions and difficulties controlling impulsive behavior when experiencing positive emotions—accounted for the relationship between depression symptom severity and risky alcohol use.

Conclusion: Results suggest the importance of incorporating techniques focused on improving positive emotion regulation skills in interventions for risky alcohol use among individuals with depression.  相似文献

Background: The relationship between living conditions in urban and rural areas during childhood and subsequent inflammatory bowel disease (IBD) remains controversial.

Aim: To explore the association between environmental exposures early in life and the subsequent risk of IBD.

Methods: Literature searches were conducted in the following databases: PubMed, EMBASE, and Conference Proceedings Citation Index. Studies were analyzed separately using rate ratios (RRs) or odds ratios (ORs) with 95% confidence intervals.

Results: The search strategy identified 15 studies. Of these, 9 studies explored the association between urban exposure during childhood and ulcerative colitis (UC), and 12 and 4 studies explored this relationship with Crohn’s disease (CD) and IBD, respectively. A meta-analysis showed that the pooled ORs estimated for the case–control studies of UC, CD, and IBD were 1.16 (0.83, 1.61), 1.45 (1.45, 1.85), and 1.34 (1.11, 1.62), respectively. The pooled RR estimated for the cohort studies of CD and IBD was 1.48 (1.17, 1.87). The stratified analysis and meta-regression showed significant relationships between CD and living conditions in case–control studies published during 2010–2017 and in non-European countries (< 0.05).

Conclusions: Living conditions during childhood are positively associated with the subsequent development of IBD. Urban living environment is more common among those with CD than UC.  相似文献

Objectives: Ethnic minority elders have high levels of social isolation and loneliness. Assumptions about the family providing enough social support exist in the literature, contradicting ethnic minority elders’ reported levels of isolation and loneliness. While structural barriers influence feelings of isolation and loneliness, limited information exists about the role of cultural factors such as acculturation and family values. Accordingly, this study investigated the roles of acculturation and family values on loneliness and social isolation among ethnic minority elders.

Methods: Ethnic minority elders (N = 123) completed a questionnaire that assessed their social connectedness, measured by social network and levels of loneliness, and structural factors such as income. Additionally, cultural and family values were assessed by acculturation and the ‘family as referents’ dimension of familism, which refers to the belief that family members’ behaviour should meet with familial expectations.

Results: Statistical analysis using hierarchical regression indicated that ‘family as referents’ and acculturation predicted loneliness, but not social network.

Conclusions: This study raises the importance of considering cultural values when investigating predictors of loneliness among ethnic minority elders.

Clinical Implications: Findings highlight the importance of addressing familial expectations in programs aimed at alleviating loneliness among ethnic minority elders.  相似文献

Objective: This study explores how older adults respond to audiovisual virtual reality (VR) and perceive its usefulness to their lives.

Method: Focus groups were conducted with residents of a retirement community after they viewed two audiovisual VR simulations (= 41). Thematic analysis was used to identify patterns in responses.

Results: Older adults described positive and negative emotional reactions to aspects of the VR experience, articulated content preferences, shared ideas to improve the usability of the equipment, and identified facilitators and barriers that influenced perceived usefulness. Recommendations for improving this technology include maximizing the positive aspects of VR through increasing interactivity, facilitating socializing with friends or family, and enhancing older adults’ ease of use. Desired content of simulations involved travel, continuing education, reminiscence, and self-care/therapy.

Conclusion: Virtual reality was reviewed positively, yet modifications are necessary to facilitate optimal user experience and potential benefit for this population.

Clinical Implications: As older adults are interested in using VR, especially if poor health prevents the continuation of desirable activities or new experiences, it is important to respond to older adults’ preferences and remove barriers that limit use and enjoyment.  相似文献

Objectives: Two studies in the early 1990s demonstrated that life narrative interviews conducted by age-peer volunteers strengthened the coping of older patients undergoing invasive medical procedures. The present article reports on the implementation of a similar life narrative interview program for medical inpatients and subsequent evaluation of the mood and coping effects of the intervention.

Methods: Three volunteers (mean age = 69 years) were trained to administer 45- to 60-minute life narrative interviews. Fifty-three inpatients (mean age = 70 years) on various units of a Mid-Atlantic non-profit hospital agreed to participate. The Positive and Negative Affect Schedule and Coping Self-Efficacy Inventory (CSEI) were administered before and after the interviews.

Results: T-tests indicated a significant increase in positive affect and decrease in negative affect following the interview but no changes in the CSEI. Patient satisfaction questions administered after the interview indicated that patients had a high level of satisfaction with the interview experience.

Conclusions: The life narrative interview program appeared to improve the overall mood of participants while providing a satisfying activity to engage in while in the hospital.

Clinical Implications: The project demonstrated a cost-effective method for employing volunteers to enhance the experience of patients at healthcare facilities.  相似文献

Objectives: The current study sought to understand the differences hospice nurses perceived in caring for older adult patients who utilize hospice for longer and shorter periods, older adult patients’ experience of hospice services, and if length of hospice stays influenced the patients’ end-of-life experience.

Methods: Interpretative Phenomenological Analysis was used to extract themes and subthemes from 10 interviews conducted with hospice nursing staff.

Results: Four major themes were identified pertaining to nurses perspective on older adults’ views of hospice and how length of hospice use impacts end-of-life care.

Conclusion: These themes suggest hospice nursing staff believe longer hospice stays are more positive and that older adults identify more positive aspects of hospice when using it for longer periods of time. Results suggest that nurses believe length of use directly impacts patient care and the experience of hospice services.

Clinical Implications: Participating nurses reported that older adults have a lack of information on hospice services. It was suggested that more information is needed and that providing such education may lead to longer hospice stays.  相似文献

Goals: To assess if curcumin improves markers of cholestasis among subjects with primary sclerosing cholangitis (PSC).

Background: PSC is a chronic cholestatic liver disorder for which there is no established medical therapy. Preclinical data suggest curcumin may have a beneficial effect in PSC.

Study: Subjects with PSC and a serum alkaline phosphatase (SAP) greater than 1.5 times the upper limit of normal (ULN) received curcumin 750?mg orally twice daily for 12 weeks in an open-label pilot study. The primary composite endpoint was proportion of subjects who had a reduction of SAP to less than 1.5 times ULN or a 40% reduction in SAP between baseline and week 12. Secondary endpoints included changes in serum aspartate aminotransferase, total bilirubin, Mayo PSC risk score and self-reported health questionnaires.

Results: Two-hundred and fifty-eight patients with PSC were screened and 15 subjects were enrolled and all completed 12 weeks of therapy. The most common reason for subject exclusion was SAP less than 1.5 times the ULN (n?=?98). Curcumin did not result in a significant median (interquartile range) change in SAP times the ULN [3.43 (2.10–4.32) to 2.46 (1.89–4.41), p?=?.36], and only 20% (3/15) subjects achieved the primary endpoint. Similarly, there was no significant change in the secondary endpoints. There were no serious adverse events reported.

Conclusion: While curcumin was well tolerated, it was not associated with significant improvements in cholestasis or symptoms. Moreover, this study also illustrates that a low SAP is common among those with PSC.

Objective: To assess the transthyretin (TTR) stabilization activity of tolcapone (SOM0226) in patients with hereditary ATTR amyloidosis, asymptomatic carriers and healthy volunteers.

Methods: A phase IIa proof-of-concept trial included two phases separated by a 6-week washout period. Phase A: single 200?mg dose of tolcapone; phase B: three 100?mg doses taken at 4?h intervals. The primary efficacy variable was TTR stabilization.

Results: Seventeen subjects were included (wild type, n?=?6; mutation TTR Val30Met, n?=?11). TTR stabilization was observed in all participants. Two hours after dosing, 82% of participants in phase A and 93% of those in phase B reached a TTR stabilization value of at least 20%. In phase A, there was an increase of 52% in TTR stabilization vs baseline values 2?h after dosing, which decreased to 22.9% at 8?h. In phase B, there was a significant increase of 38.8% in TTR stabilization 2?h after the first 100?mg dose. This difference was maintained after 10?h and decreased after 24?h. No serious adverse events were observed.

Conclusions: The ability of tolcapone for stabilizing TTR supports further development and repositioning of the drug for the treatment of ATTR amyloidosis.

Objectives: Mental health factors, such as PTSD, can exacerbate typical age-related cognitive changes and lead individuals to have subjective concerns for which few interventions presently exist. This study evaluates self-reported mental health outcomes following a psychoeducational memory skills program designed for veterans over 50 with subjective memory concerns in the context of PTSD. It was hypothesized that outcomes would improve following program participation and that baseline cognitive self-efficacy would moderate improvements in self-reported depression and life satisfaction.

Methods: Veterans (n = 101, age ≥ 51) participated in an 8-week memory skills program and completed baseline and post-program assessment data as part of a quality improvement project.

Results: Life satisfaction and cognitive self-efficacy demonstrated significant improvement following participation in the memory skills program. Cognitive self-efficacy was found to significantly modify change in depressive symptoms.

Conclusions: We found improvement in mental health outcomes following participation in a psychoeducational memory skills program, with differential impact on depressive symptoms for those with low baseline cognitive self-efficacy.

Clinical Implications: Participation in this intervention led to improved life satisfaction and cognitive self-efficacy. Cognitive self-efficacy, in turn, appeared to have implications for improving depressive symptomology and may be a useful target of memory skills education.  相似文献

Background: A greater understanding of mechanisms explaining the interactions between diet and the gut microbiota in colorectal cancer is desirable. Genotoxic microbial metabolites present in the colon may be implicated in carcinogenesis and potentially influenced by diet.

Aims: We hypothesised that microbial p-cresol is a colonic genotoxin and set out to model potential exposures in the colon and the effects of these exposures on colonic cells.

Methods: Batch culture fermentations with human faecal inoculate were used to determine the synthesis of p-cresol and other metabolites in response to various substrates. The fermentation supernatants were evaluated for genotoxicity and the independent effects of p-cresol on colonic cells were studied in vitro.

Results: In batch culture fermentation, supplementary protein increased the synthesis of phenols, indoles and p-cresol, whereas supplementary fructoligosaccharide (FOS) increased the synthesis of short chain fatty acids. The p-cresol was the greatest predictor of genotoxicity against colonocytes in the fermentation supernatants. Spiking fermentation supernatants with exogenous p-cresol further increased DNA damage, and independently p-cresol induced DNA damage in a dose-dependent manner against HT29 and Caco-2 cells and influenced cell cycle kinetics.

Conclusions: In the colon p-cresol may reach physiologically significant concentrations which contribute to genotoxic exposures in the intestinal lumen, p-cresol production may be attenuated by substrate, and therefore diet, making it a potential modifiable biomarker of genotoxicity in the colon.  相似文献

Background: We aimed to investigate the role of intracellular imatinib concentration in drug resistance and the expression of candidate drug transporters in gastrointestinal stromal tumor (GIST) cell lines.

Method: The imatinib concentrations were measured by the liquid chromatography-tandem mass spectrometry (LC-MS/MS). The expression of candida te drug transporters was detected by qRT-PCR.

Results: The tissue imatinib concentrations in imatinib resistant patients were significantly lower than that of sensitive patients (p?<?.05). Compared with parental cell lines, the intracellular imatinib concentration was notably lower in imatinib resistant GIST cell lines. For candidate transporters, MRP1 and BCRP were overexpressed in resistant GIST cell lines.

Conclusion: The intracellular imatinib concentration may play a crucial role in imatinib resistance and the intracellular differences of imatinib concentration may be induced by the upregulation of efflux transporters. Our study highlights the importance of intracellular imatinib concentration and the potential of using imatinib transporters as therapeutic targets for patients with GIST.  相似文献

Over the recent years, the pathophysiology of the inflammatory component in hypertension has been a challenge, because this inflammatory response is mainly contributed by an increased oxidative stress with the release of inflammatory mediators. Identification of a simple and early inflammatory marker such as the neutrophil-to-lymphocyte ratio (NLR) is the need of the hour. This study correlates the same specifically taking into account the duration and the grades of hypertension.

Objective: The response of the NLR among the hypertensives and its correlation with duration and stages of hypertension.

Method: Totally, 80 subjects and 40 controls of age between 20 and 60 years and both genders were included. Three recordings of blood pressure were measured with a standard mercury sphygmomanometer. The differential leukocyte count was estimated with an automated Beckman Coulter.

Objective: Variations in the neutrophil and lymphocyte counts were significant among the hypertensives with a p-value < 0.001. The NLR was also significantly altered among the hypertensives with a p-value = 0.001. The NLR showed a rise in value among the normotensives, prehypertensives, and stage 1 of systolic hypertension, though not statistically significant. An increase in the NLR was observed in hypertensives with duration of 1–2 years.

Conclusion: Our study gives a new insight with a rise in NLR in early years and even among prehypertensives and stage 1 systolic hypertension under strict criterion. This could be utilized as an early predictive tool, relating the inflammatory process and hypertension which on further intervention could slow the progression of the disease process.

Abbreviations: NLR: Neutrophil-to-lymphocyte ratio; BP: Blood pressure.  相似文献

Objectives: To determine the feasibility, acceptability and initial efficacy of telephone-delivered cognitive behavioral therapy (CBT) for the treatment of anxiety and depressive symptoms in people with Parkinson’s disease.

Methods: A small randomized controlled trial compared telephone-based CBT to waitlist control. Eleven participants aged >50 years with Parkinson’s disease and anxiety and/or depressive symptoms above recommended clinical cut-offs, were randomized to one of two conditions. Participants completed self-report measures of symptom severity and quality of life. Their carers were invited to participate and completed self-reported measures of symptoms and carer burden. At the end of the 10-week intervention period, participants and carers were reassessed on baseline measures, and again one month later.

Results: The CBT program was associated with significantly reduced depressive symptoms (Cohen’s d = .90) at post-treatment with gains maintained at one-month follow-up. Anxiety symptom decreases (Cohen’s d = 0.36) were not statistically different. Waitlist was associated with significantly worsened anxiety. Carer symptoms also reduced with CBT. No changes on quality of life were found. Good acceptability and feedback was received.

Conclusions: Telephone-based CBT reduced symptoms of depression in participants with Parkinson’s disease but not anxiety.

Clinical Implications: Telephone-based CBT is a promising treatment option.  相似文献

Background: Seronegative celiac disease (CD) poses a diagnostic challenge.

Aims: Characterize and identify differences between seronegative and seropositive CD.

Patients and methods: Retrospective cohort study examining adult patients diagnosed with CD (1980–2017). Clinical, analytical, histological, genetic and immunophenotypic data were compiled. Seronegative CD was defined as a anti-tissue transglutaminase type 2 IgA and endomysial antibodies (EMA) negative and HLA-DQ2 and/or DQ8 positive, showing clinical signs of CD plus an abnormal duodenal biopsy, and responding to a gluten-free diet (GFD). Factors associated with seronegative CD were identified through binomial logistic regression.

Results: Of 315?CD patients, 289 were seropositive (91.7%) and 26 seronegative (8.3%). Among the seronegative patients, higher prevalence was observed for autoimmune thyroiditis (26.9% vs. 9.7%, p?=?.016), HLA-DQ8 heterozygosity (23.1% vs. 2.5%, p???.001) and Marsh I lesion (34.6% vs. 3.7%, p???.001). The two groups showed similar flow cytometry-determined duodenal immunophenotypes and rates of refractory CD.

Conclusions: Seronegative CD differs mostly in genetic (more HLA-DQ8) and histologic (milder atrophy) features as compared with seropositive. Intestinal intraepithelial immunophenotype by flow cytometry, similar in both modalities, is a useful tool to diagnose seronegative CD.  相似文献

Background: The role of specific cerebral areas involved in alcohol use disorder, such as the amygdala, hippocampus and prefrontal cortex, has emerged as a subject of interest over recent years. Nevertheless, the role played by these regions is frequently confounded by different variables, among them are the patterns of alcohol consumption presented by the subjects.

Objectives: The present study verified the effects of chronic voluntary ethanol intake (20 sessions) on DeltaFosB immunoreactivity (DeltaFosB-ir) in the amygdala, hippocampus and prefrontal cortex of rats showing high and low preference for ethanol.

Methods: DeltaFosB-ir induced by chronic voluntary ethanol intake with a two-bottle intermittent access to 20% ethanol model in male Wistar rats was measured. Three groups of animals were analyzed: control (n = 6), low preference (n = 8) and high preference (n = 8) for ethanol, the latter two categorized from their pattern of voluntary consumption of the alcohol solution.

Results: Ethanol intake in high-preference rats increased DeltaFosB-ir in the central amygdala, CA1 and CA3 regions of the hippocampus and decreased DeltaFosB-ir in the prelimbic cortex and anterior cingulate cortex. On the other hand, in low preference rats, chronic voluntary ethanol intake decreased DeltaFosB-ir in the medial amygdala, basolateral amygdala, dentate gyrus and anterior cingulate cortex.

Conclusions: The present results suggest that different alcohol intake patterns are associated with a specific pattern of DeltaFosB-ir in brain structures that play a key role in controlling behavior and decision making, that is the amygdala, the hippocampus and the prefrontal cortex.  相似文献

Background: Inflammatory bowel diseases patients eligible for biological therapy represent a group with considerable disease burden and biologics only achieve 40% clinical remission rates in responders after 1 year of therapy.

Aims: To collect all the published data about patients treated with dual biological therapy with an Anti-TNF, vedolizumab or ustekinumab, for a period of at least 3 months and to pool the data about the effectiveness and safety.

Methods: A MEDLINE, and Web of Science search of all studies published in English until 1 January 2019 was conducted.

Results: We included 7 studies with a total of 18 patients. Fifteen patients were treated with a combination of an anti-TNF and vedolizumab, 3 patients were treated with vedolizumab and ustekinumab. Fifty-six percent of patients were affected by Crohn’s disease and 50% of patients were treated with an immunosuppressant drug or steroid too. A clinical improvement was obtained in 100% of patients, and an endoscopic improvement in 93% of patients. No serious adverse events were reported.

Conclusions: The use of dual biological therapy is an attractive therapeutic option and may be an opportunity to better tailor and personalize the therapies for patients. Further studies, as randomized control trials, to provide comparative efficacy and safety endpoints of combination therapies, and to clarify potential advantages of combined biological therapies, are needed.  相似文献

Background and Objective: Despite the growth of financial exploitation research in the past decade, almost none has focused on older urban adults, and especially urban African Americans. The Success After Financial Exploitation (SAFE) program provides individual financial coaching to older urban adults.

Methods: We use community education, delivered separately to older adults and to the professionals who serve them, to raise awareness about financial exploitation (FE) and to motivate referrals for financial coaching. This paper describes the program and methodology, and uses case examples and preliminary research to investigate the intersection of FE and physical and mental health functioning.

Results: SAFE participants were able to repair their credit scores, reduce new financial burdens, and even recover monies they had lost due to FE. Case examples illustrate how financial scams and identity theft impacts urban older adults. Participants were assessed prior to the provision of services, and SAFE participants performed poorer on executive functioning tasks than participants in the control group. They also reported more physical health problems and anxiety and depressive symptoms. SAFE participants also had significantly higher risk scores on a financial decision-making scale.

Conclusion: Study findings advance our understanding of the impacts of FE on cognitive functioning, mental health, and financial decision-making.

Clinical Implications: Clinicians need to be more attuned to the financial health of their older clients, who, if they are struggling with financial exploitation, may also be suffering from problems with cognitive functioning and physical and mental health.  相似文献
