Sensitivity for Change Analyses of the Patient-Reported Outcomes in Obesity (PROS) Questionnaire: A Prospective Cohort Study. Patient Relat Outcome Meas 2023; 14:235-241. [PMID: 37547056 PMCID: PMC10404038 DOI: 10.2147/prom.s414144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Accepted: 06/30/2023] [Indexed: 08/08/2023] Open
Abstract
Purpose Many patients seeking bariatric surgery experience reduced health-related quality of life (HRQOL). A simple clinical tool, the Patient-Reported Outcomes in Obesity (PROS), was developed to address patients' HRQOL concerns during clinical consultations and facilitate meaningful dialogue. The present study aims to explore its sensitivity to change. Patients and Methods A prospective study of patients undergoing bariatric surgery was conducted. The patients responded to items on the PROS and the Obesity-related Problems Scale (OP) before surgery and three, 12 and 24 months after surgery. Longitudinal mixed-effects models were applied to estimate the change in PROS and OP scores over time. Results Thirty-eight patients were included. A significant change over time was detected for the PROS with the largest effect size at 24 months (effect size -1.34, p ˂ 0.001), while the corresponding effect size for the OP was -1.32 (p ˂ 0.001). In all items of the PROS, the majority of patients responded not bothered at 24 months. The items physical activity, pain, sleep and self-esteem showed the largest change in the percentage of patients reporting not bothered from baseline to 24 months after surgery. Conclusion The PROS is sensitive to change over time and may be used as a brief, easy to administer tool to facilitate a conversation about obesity-specific quality of life in clinical consultations.

Experiences and results from using a novel clinical feedback system in routine stoma care nurse follow-up of patients with an ostomy: a longitudinal study. J Patient Rep Outcomes 2023; 7:27. [PMID: 36913078 PMCID: PMC10010226 DOI: 10.1186/s41687-023-00573-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 03/04/2023] [Indexed: 03/14/2023] Open
Abstract
BACKGROUND A faecal or urinary ostomy may be lifesaving. However, it involves significant bodily change, and the adjustment process to life with an ostomy includes a broad spectre of physical and psychosocial challenges. Thus, new interventions are needed to improve adaptation to living with an ostomy. This study aimed to examine experiences and outcomes using a new clinical feedback system with patient-reported outcome measures in ostomy care. METHODS In this longitudinal explorative study, 69 ostomy patients were followed by a stoma care nurse in an outpatient clinic, using a clinical feedback system postoperatively at 3, 6 and 12 months. The patients responded electronically to the questionnaires before each consultation. The Generic Short Patient Experiences Questionnaire was used to measure patient experiences and satisfaction with follow-up. The Ostomy Adjustment Scale (OAS) measured adjustment to life with an ostomy, and the Short Form-36 (SF-36) assessed the patient's health-related quality of life. Longitudinal regression models with time as an explanatory (categorical) variable were used to analyse changes. The STROBE guideline was applied. RESULTS The patients were satisfied with their follow-up (96%). Especially, they felt they received sufficient and individualised information, were involved in treatment decisions, and benefited from the consultations. The OAS subscale scores for 'daily activities', 'knowledge and skills' and 'health' improved over time (all p < 0.05), as did the physical and mental component summary scores of the SF-36 (all p < 0.05). Effect sizes of changes were small (0.20-0.40). Sexuality was the most challenging factor reported. CONCLUSIONS The clinical feedback system could be helpful because outpatient follow-ups for ostomy patients may be more tailored when clinicians use clinical feedback systems. However, further development and testing are needed.

Factors associated with leakage in patients with an ostomy: A cross-sectional study. Nurs Open 2023; 10:3635-3645. [PMID: 36691880 PMCID: PMC10170928 DOI: 10.1002/nop2.1612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 11/01/2022] [Accepted: 12/16/2022] [Indexed: 01/25/2023] Open
Abstract
AIMS To explore the associations between sociodemographic and clinical data, the patient's knowledge and skills, and relationship to healthcare professionals with leakage from an ostomy. DESIGN Cross-sectional. METHODS This study included 160 patients with a colostomy, ileostomy, or urostomy. Leakage was the dependent variable and was assessed by self-report. Sociodemographic and clinical data and the Ostomy Adjustment Scale subscores, 'knowledge and skills' and 'health care professionals' were independent variables. Spearman's rho and multivariate partial least squares regression analysis were used to estimate possible factors associated with leakage. RESULTS Of the participants, 13.8% had leakage weekly or more often, 16.3% more often than once a month and 37, 5% had leakage more seldom than once a month. The most important risk factors for leakage were (1) having an ostomy placement that does not meet international guidelines, (2) not having an optimal relationship with health professionals, (3) having a diagnosis other than cancer, (4) not having proper knowledge and skills in ostomy care, (5) not having a colostomy, (6) having a convex baseplate, (7) having an oval ostomy, and (8) being dependent on others for ostomy care. The independent variables in the PLS- model explained 31% of the variance in leakage. PATIENT OR PUBLIC CONTRIBUTION We thank the patients in the user panel for their help during the study.

Outcomes of the first global multidisciplinary consensus meeting including persons living with obesity to standardize patient-reported outcome measurement in obesity treatment research. Obes Rev 2022; 23:e13452. [PMID: 35644939 PMCID: PMC9539945 DOI: 10.1111/obr.13452] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Revised: 03/07/2022] [Accepted: 03/08/2022] [Indexed: 11/30/2022]
Abstract
Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the key PROs and preferred PROMs for obesity treatment research. It comprised of 35 people living with obesity (PLWO) and healthcare providers (HCPs). Formal presentations, nominal group techniques, and modified Delphi exercises were used to develop consensus-based recommendations. The following eight PROs were considered important: self-esteem, physical health/functioning, mental/psychological health, social health, eating, stigma, body image, and excess skin. Self-esteem was considered the most important PRO, particularly for PLWO, while physical health was perceived to be the most important among HCPs. For each PRO, one or more PROMs were selected, except for stigma. This consensus meeting was a first step toward standardizing PROs (what to measure) and PROMs (how to measure) in obesity treatment research. It provides an overview of the key PROs and a first selection of the PROMs that can be used to evaluate these PROs.

The impact of educational concerns and satisfaction on baccalaureate nursing students' distress and quality of life during the Covid-19 pandemic; a cross-sectional study. BMC Nurs 2022; 21:185. [PMID: 35820841 PMCID: PMC9274954 DOI: 10.1186/s12912-022-00962-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 06/22/2022] [Indexed: 11/10/2022] Open
Abstract
Background High levels of psychological distress and poor overall quality of life (QOL) have been identified among nursing students during the COVID-19 pandemic. The pandemic necessitated improvised reconstructions of educational curriculums and restrictions in clinical placement and training at campuses, possibly reducing educational quality. Objectives We explored whether baccalaureate nursing students’ concerns and satisfaction with the educational curriculum, focusing on the conduct of clinical training, were associated with perceived psychological distress and overall QOL. Methods Baccalaureate nursing students (N=6088) from five Norwegian universities were invited to an internet-based, cross-sectional survey during the second wave of the pandemic. The survey included COVID-19 specific questions on health, education and clinical training, the Fear of COVID-19 scale (FCV-19S), The Hopkins Symptom Checklist (SCL-5) and overall QOL. Data from national surveys on satisfaction with the educational curriculum, before and during the pandemic were used for comparison. Results In total, 2605 (43%) students responded, of whom 1591 (61%) had been engaged in clinical training during the pandemic. Overall, 53% were either satisfied or fully satisfied with their educational curriculum, with the level of satisfaction being significantly lower than pre-pandemic reference values. Also, 79% were concerned or highly concerned about the educational quality. In multiple regression analyses for all students, lower levels of satisfaction and higher levels of quality concerns were associated with worse SCL-5 scores. Furthermore, satisfaction with the educational curriculum was positively associated with overall QOL. For students engaged in clinical training, only concerns about infecting others were additionally associated with psychological distress. None of the items related to clinical training were associated with overall QOL. Conclusion Nursing students’ educational satisfaction and quality concerns may significantly impact perceived psychological distress and overall QOL during a pandemic. However, with necessary adaptations implemented, concerns regarding the conduct of clinical training account for little of these associations.

Correlated physical and mental health composite scores for the RAND-36 and RAND-12 health surveys: can we keep them simple? Health Qual Life Outcomes 2022; 20:89. [PMID: 35659237 PMCID: PMC9166415 DOI: 10.1186/s12955-022-01992-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 05/17/2022] [Indexed: 11/30/2022] Open
Abstract
Background The RAND-36 and RAND-12 (equivalent to versions 1 of the SF-36 Health Survey and SF-12 Health Survey, respectively) are widely used measures of health-related quality of life. However, there are diverging views regarding how to create the physical health and mental health composite scores of these questionnaires. We present a simple approach using an unweighted linear combination of subscale scores for constructing composite scores for physical and mental health that assumes these scores should be free to correlate. The aim of this study was to investigate the criterion validity and convergent validity of these scores.
Methods We investigated oblique and unweighted RAND-36/12 composite scores from a random sample of the general Norwegian population (N = 2107). Criterion validity was tested by examining the correlation between unweighted composite scores and weighted scores derived from oblique principal component analysis. Convergent validity was examined by analysing the associations between the different composite scores, age, gender, body mass index, physical activity, rheumatic disease, and depression.
Results The correlations between the composite scores derived by the two methods were substantial (r = 0.97 to 0.99) for both the RAND-36 and RAND-12. The effect sizes of the associations between the oblique versus the unweighted composite scores and other variables had comparable magnitudes.
Conclusion The unweighted RAND-36 and RAND-12 composite scores demonstrated satisfactory criterion validity and convergent validity. This suggests that if the physical and mental composite scores are free to be correlated, the calculation of these composite scores can be kept simple.

The Norse Feedback in a population of patients undergoing bariatric surgery-Psychometric properties of a digital computer-adaptive questionnaire assessing mental health. Clin Obes 2022; 12:e12491. [PMID: 34761876 DOI: 10.1111/cob.12491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 09/08/2021] [Accepted: 09/28/2021] [Indexed: 11/27/2022]
Abstract
The Norse Feedback (NF) is a questionnaire developed for patient-reported outcome monitoring with a clinical feedback system (PRO/CFS). As mental health is a concern after bariatric surgery, the use of the NF as part of PRO/CFS may be beneficial. The aim of this study is to test the reliability and validity of the NF in patients who have been accepted for or have undergone bariatric surgery. We performed separate robust confirmatory factor analyses (CFAs) to test the unidimensionality on 19 of the NF scales. We also performed correlation analyses on 19 of the NF scales with the Obesity-related Problems scale (OP). We included 213 patients. In the CFA analyses, three out of 12 scales with four or more items showed satisfactory psychometric properties in all goodness of fit indices (Suicidality, Need for Control and Self-Criticism). Four scales showed satisfactory psychometric properties in all indices but RMSEA (Somatic Anxiety, Substance Use, Social Safety and Cognitive Problems). Several of the scales demonstrated floor effects. In the correlation analyses, 18 of the 19 scales showed small-to-moderate correlation coefficients with the OP. Our demonstration of satisfactory psychometric properties on several important scales of the NF suggests that this tool may prove valuable in the routine follow-up of mental health in this population. However, further work is needed to innovate the NF for patients undergoing bariatric surgery.

Effects of a school-based intervention on levels of anxiety and depression: a cluster-randomized controlled trial of the MindPower program in ten high schools in Norway. BMC Psychol 2022; 10:14. [PMID: 35074007 PMCID: PMC8788112 DOI: 10.1186/s40359-022-00721-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 01/12/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The previous decades have shown increased symptoms of depression and anxiety among adolescents. To promote mental health and reduce mental illness, the government of Norway has, as in other countries, pledged that all schools must incorporate life-skills education. We report results from an evaluation of MindPower, a modification of the Coping With Depression (CWD) course, delivered universally in the classroom to secondary high school students, aged 15-16 years, in one county in Norway. The aim of the study was to evaluate the effect of MindPower on symptoms of depression and anxiety. METHODS We utilized a two-groups` delayed intervention design where 110 first year high school classes were randomized into one of two intervention groups (IG1 and IG2). IG1 participated in MindPower while IG2 served as a control group for four months until the intervention started also in this group. IG1 and IG2 responded to questionnaires before and after the eight weeks course, at the start of the first and the second booster session, and at the five months follow up. Questionnaires, including online versions of the Hopkins Symptom Checklist (SCL-8) and the Reynolds Adolescent Depression Scale (RADS-2:SF), were administered to 1673 out of a total of 2384 students. SCL-levels were also compared with those from a large population study (UngData). RESULTS According to mixed model analyses, SCL-8 and RADS-2:SF showed significant baseline differences between IG1 and IG2. In IG1 and IG2, both SCL-8 and RADS-2:SF showed a small but significant increase in mean scores throughout the study period, with markedly lower mean scores among boys. The SCL-levels were first lower for both girls and boys and then after the completion of MindPower the SCL-levels, equal to the SCL-levels in UngData. CONCLUSIONS No effects of the intervention were found. This large universal school-based trial suffered from considerable drop-out of participants. Experiences from implementation and evaluation of universal mental health promotion and preventive school interventions are thoroughly discussed, including, preparation, resources, support, time, realistic expectations, teacher selection and training, implementation, research designs and more. Several empirically based, practical advices are presented. Clinical Trial registration 27/08/2018. Registration number NCT03647826.

Quality of life and fear of COVID-19 in 2600 baccalaureate nursing students at five universities: a cross-sectional study. Health Qual Life Outcomes 2021; 19:198. [PMID: 34412630 PMCID: PMC8374118 DOI: 10.1186/s12955-021-01837-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 08/06/2021] [Indexed: 12/20/2022] Open
Abstract
Background The COVID-19 pandemic has caused significant disruptions in the implementation of programs across educational institutions. Nursing students, being both young adults and by practical training, part of the health care system, may be particularly vulnerable during the COVID-19 pandemic. The purpose of this study was to explore the associations between self-reported fear of COVID-19, general health, psychological distress and overall quality of life (QoL) in a sample of Norwegian baccalaureate nursing students compared to reference data.
Methods The survey targeted baccalaureate nursing students from five universities in February 2021. An electronic questionnaire consisted of the Fear of COVID-19 Scale (FCV-19S), the Hopkins Symptom Checklist 5 (SCL-5), one general health and one overall QoL question. The respondents’ mean scores were compared to reference data. Hierarchical regression analyses were conducted, and effect sizes (Cohen’s d) were evaluated. Results In total, 2605 out of 6088 (43%) students responded. Their FCV-19S scores (mean 2.45, CI 2.42, 2.48) were significantly higher than those of the reference population (mean 1.8, P < 0.001). Nursing students scores showed significantly lower general health (mean 3.50 ± 0.93 SD, population mean = 3.57, Cohen’s d = 0.07), higher levels of psychological distress (mean 2.68 ± 1.03 SD, population mean = 2.12, Cohen’s d = 0.55) and lower overall QoL (mean 5.50 ± 2.16 SD, population mean = 8.00, Cohen’s d = 1.16) compared to pre-pandemic reference data. FCV-19S scores were significantly associated with levels of general health (Cohen’s d = 0.26), psychological distress (Cohen’s d = 0.76) and overall QoL (Cohen’s d = 0.18). Conclusions Baccalaureate nursing students reported worse outcomes during the Covid-19 pandemic on general health, psychological distress and overall QoL compared to the reference population. Level of fear of Covid-19, however, accounted for few of these differences. Other factors related to the pandemic may have reduced nursing students’ overall QoL.

Does moderate intensity impact exercise and non-impact exercise induce acute changes in collagen biochemical markers related to osteoarthritis? - An exploratory randomized cross-over trial. Osteoarthritis Cartilage 2021; 29:986-994. [PMID: 33676014 DOI: 10.1016/j.joca.2021.02.569] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Revised: 02/17/2021] [Accepted: 02/25/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To investigate acute changes in biochemical markers of cartilage turnover in response to moderate intensity exercise with and without joint impact in humans with knee osteoarthritis. DESIGN We conducted a randomized, cross-over, exploratory clinical study. Twenty subjects with knee osteoarthritis (OA) were randomized, of which twenty completed 30 min of cycling and 15 completed 30 min of running on days 1 week apart. Fasting blood samples were taken before, immediately after and 1, 2, 3, and 24 h after activity was initiated. Midstream spot urine was sampled before and after activity. Serum samples were analyzed for concentrations of fragment of type II collagen degradation, C2M, fragment of type VI collagen degradation, C6M, cartilage oligomeric matrix protein, COMP, marker of type II collagen formation, PRO-C2, and urine for marker of crosslinked type II collagen degradation, CTX-II. To establish a reference, all subjects had similar samples taken during rest on a separate day. Data was analyzed in a restricted maximum likelihood based random effects linear mixed model. RESULTS C2M trended to increase after cycling compared running (13.49%, 95%CI: -0.36-27.34%) and resting (12.88%, 95%CI: 0.2-25.6%) and the type II collagen formation/degradation ratio switched towards degradation after cycling, but not running. C6M trended to decrease after cycling (-8.1%, 95%CI: -14.8 to -1.4%) and running (-6.8%, 95%CI: -14.16-0.55%). CONCLUSION In persons with knee OA moderate intensity exercise without joint impact may induce acute changes in circulating levels of biochemical markers reflecting type II and VI collagen degradation.

Abstract
BACKGROUND The Ostomy Adjustment Scale (OAS), which consists of an overall sum score along with 34 single-item scores, has been frequently used to measure self-reported adjustment to life with an ostomy. However, it is unknown whether the OAS can be divided into meaningful thematic subscales that may make it easier to administer and to apply in a clinical feedback system. PURPOSE The purpose of this study was to specify thematic OAS subscales and evaluate their psychometric properties. PATIENTS AND METHODS A cross-sectional study was conducted with 302 patients across Norway having colostomy, ileostomy, or urostomy. The OAS items were divided into different subscales by expert nurses and patients based on clinical and theoretical considerations. The overall structural validity of this analysis of the OAS was examined using robust confirmatory factor analysis. We evaluated the overall goodness of fit using the root mean square error of approximation (RMSEA), the comparative fit index (CFI) and the Tucker-Lewis index (TLI). Factor loadings from the confirmatory factor analysis were used to calculate composite reliability values for the new OAS scales. RESULTS The OAS was divided into seven subscales. The overall structure validity was acceptable with RMSEA = 0.053 (90% CI, 0.045-0.060), CFI = 0.913 and TLI = 0.904. The composite reliability values of all scales were >0.70. CONCLUSIONS The OAS can be divided into seven clinically meaningful subscales with acceptable psychometric properties. TRIAL REGISTER ClinicalTrials.gov Registration Number: NCT03841071. Date 18.

Abstract
BACKGROUND Consultations before and after bariatric surgery should include structured assessments of patients' health-related quality of life (HRQOL) and mental health. One way to conduct this assessment is to implement patient-reported outcome monitoring with a clinical feedback system (PRO/CFS). AIM We will explore patients' and healthcare professionals' experiences when a PRO/CFS is an integrated part of bariatric surgery care. METHODS AND ANALYSES This is a design paper in which a PRO/CFS will be implemented in two bariatric outpatient clinics. All patients who have an appointment with a healthcare professional prior to, and 3 and 12 months after surgery, will be asked to complete six digital questionnaires measuring HRQOL, mental health, bowel symptoms and eating self-efficacy prior to each consultation. A digital summary report generated from the patient's responses will form the basis for the clinical consultation. A team of patient representatives, healthcare professionals and researchers will be involved in all phases of designing the PRO/CFS to ensure its relevance for clinical consultations. The patients' experiences will be explored with a generic 12-item questionnaire, developed for use in outpatient clinics, prior to and 12 months after bariatric surgery. We will conduct focus-group interviews with patients and healthcare professionals to explore their experiences when PRO/CFS is integrated into the consultations. ETHICS AND DISSEMINATION Written informed consent will be obtained for all participants in the study. The project is approved by the Norwegian Centre for Research Data, Department of Data Protection Services (ref. no. 282738). The project has also undergone Data Protection Impact Assessments, both at Førde Hospital Trust and at St. Olav Hospital (registration no. 2016/3912). Data from the qualitative and quantitative studies will be kept in de-identified form in a secured research database, and the findings will be published in international peer-reviewed journals and presented at scientific conferences.

Abstract
BACKGROUND The long-term prognosis after cognitive behavioral therapy (CBT) in outpatient groups for panic disorder and agoraphobia is not well known. The purpose of this study was to assess long-term outcomes in terms of psychological health, health-related quality of life (HRQoL), quality of life (QoL) and treatment satisfaction after CBT for panic disorder and agoraphobia. METHODS The sample consisted of 68 patients (61% response rate), who were assessed at pretreatment; at the start and end of treatment; and after 3 months, after 1 year, and over the long term (M = 24 years; SD = 5.3; range: 12 to 31 years). The main outcome was the total score on the Phobic Avoidance Rating Scale (PARS-total). At long-term follow-up, HRQoL was measured with the RAND-12 questionnaire, and QoL was measured with two questions from the "Study on European Union Statistics on Income and Living Conditions". Patient experiences and treatment satisfaction were assessed by the Generic Short Patient Experiences Questionnaire. A marginal longitudinal model was applied to study the main outcome. RESULTS The effect size of the long-term change (mean change/ pooled SD) in the PARS-total score was (- 1.6, p < 0.001) and was stable over time. A PARS-total score reduction of 50% was found in 98% of patients at the long-term follow-up. The patients' HRQoL and QoL were similar to the expected scores for the general Norwegian population. Of the patients, 95% reported high to very high satisfaction with the CBT, and 93% reported large treatment benefits. CONCLUSIONS To the best of our knowledge, this study has the longest follow-up after group CBT for panic disorder and agoraphobia, showing a good prognosis in ≥93% of the participating patients.

[PMID: 32380030 DOI: 10.1016/j.jhin.2020.04.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 04/27/2020] [Indexed: 11/29/2022]
Abstract
Contaminated hands may contribute to the transmission of pathogens. In the prevention of healthcare-associated infections the effect of disinfection methods should ideally be possible to measure in a simple way. Microbial cultivation is the reference standard, but it is a rather complicated and time-consuming procedure, and the use of swabs for measuring adenosine triphosphate (ATP) has become a much-used proxy measurement (bioluminescence). We evaluated the effect of three hand-disinfection methods on eradication of Escherichia coli from artificially contaminated hands, using cultivation and ATP measurements in parallel. ATP measurement was found to be an unsuitable method as this reflects the total amount of cellular material left on the hands, not only the viable bacteria.

A new model of patient-reported outcome monitoring with a clinical feedback system in ostomy care: rationale, description and evaluation protocol. Health Qual Life Outcomes 2020; 18:12. [PMID: 31941516 PMCID: PMC6961299 DOI: 10.1186/s12955-019-1261-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2019] [Accepted: 12/18/2019] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Living with an ostomy can be challenging and adapting to life with an ostomy can be particularly complex, with regard to both the physical and psychosocial aspects. Follow-up with a stoma care nurse (SCN) is usually performed after surgery to support the adaptation process. In the present paper, we describe a new model of ostomy care, where a clinical feedback system (CFS) is implemented in order to improve the adaption process of patients with an ostomy. We also present a plan for evaluating patients experience with the CFS and their clinical outcomes. METHODS In this study, we include patients who had recently performed colostomy, ileostomy, or urostomy surgery. The intervention includes self-reported measures for adaptation to life with an ostomy and health-related quality of life (HRQoL), as well as patient experiences and satisfaction recorded by the clinical feedback system. The measures are electronically assessed before each clinical consultation at 3, 6, and 12 months after surgery. The scores are instantly analysed and graphically presented for use during the consultation and the patient and the SCN can discuss the findings. Patient experiences and satisfaction with care will be measured with the Generic Short Patient Experiences Questionnaire. Adaptation to the life with ostomy will be measured with the Ostomy Adjustment Scale, and HRQoL with the Short Form 36. DISCUSSION This study presents a novel approach that could lead to improved consultation, more patient involvement, and better adaptation to life with an ostomy.

An Experientially Derived Model of Flexible and Intentional Actions for Weight Loss Maintenance After Severe Obesity. Front Psychol 2019; 10:2503. [PMID: 31798491 PMCID: PMC6863797 DOI: 10.3389/fpsyg.2019.02503] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 10/22/2019] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Knowledge about non-surgical weight loss (WL) is scarce among people with severe obesity (SO). Lifestyle changes are primarily self-driven, occasionally accompanied by professional guidance and weight-management support. Weight regain and intervention discontinuation are common challenges among guidance and support programmes. In the current study, we describe a model of meaningful strategies for maintaining WL after SO based on the experiences of successful cases. METHODS Aiming to investigate the experiences of WL and weight loss maintenance (WLM) (≥5 years) following SO, we designed a qualitative study. Ten adults of Norwegian ethnicity, eight women and two men aged from 27 to 59, participated in individual in-depth interviews. We recruited participants living in rural districts and cities across all four regions of Norway. The interviews concentrated on participants' experiences of losing weight and maintaining a lower weight over the long term. The transcripts were analysed with a rigorous method for thematic cross-case analysis, namely, systematic text condensation (STC). RESULTS Participants identified four experiential themes at the core of long-term WLM: (a) Owning the decision, (b) Creating self-reinforcement, (c) Sustaining a lifestyle-forming identity, and (d) Selecting support appropriate to one's own situation. These core themes represent the intentional level, functioning both as the foundation of and the momentum for sustaining WL. On the behavioural level, participants continued to take action for change, obtain results, record and reflect on their efforts and milestones, observe what worked and felt good, and receive recognition from others, thereby realising changes. CONCLUSION Based on these results, we propose a model of WLM after SO, suggesting that practices toward WLM on the behavioural level achieve meaning and sustainability through their relationship with a core intentional level found across participants' experiences. One implication is that the relationship between the intentional and behavioural levels might be more meaningful when discussing long-term WLM than the behaviours themselves.

The association between specific neuropsychiatric disturbances in people with Alzheimer's disease and dementia with Lewy bodies and carer distress. Int J Geriatr Psychiatry 2019; 34:1421-1428. [PMID: 31050041 DOI: 10.1002/gps.5134] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 04/12/2019] [Indexed: 01/01/2023]
Abstract
OBJECTIVE Neuropsychiatric symptoms (NPSs) are identified as important care-recipient variables in terms of the impact on carer distress. The aim of this study was to determine whether specific neuropsychiatric disturbances in people with Alzheimer disease (AD) and dementia with Lewy bodies (DLB) differentially impact carer distress. METHODS This was a cross-sectional study of people diagnosed with AD and DLB and their primary carers. The Relatives' Stress Scale (RSS) was used to assess the level of reported distress in carers, and the Neuropsychiatric Inventory (NPI) was used to assess NPSs. The effect of NPSs on carer distress was analyzed using correlation analysis and partial least squares regression. RESULTS This study included 159 participants diagnosed with AD (n = 97) and DLB (n = 62) and their primary carers (spouses and adult children). The majority of people diagnosed with dementia were women (64.2%), with a mean age of 75.9 years (SD, 7.4) and a mean Mini-Mental State Examination (MMSE) score of 23.5 (SD, 2.9). The main analysis identified apathy as the most important NPS contributing to carer distress. Compared with AD, the explained variance in the DLB group was higher (r2 = 37.3 vs r2 = 53.7). In addition, more NPSs were considered clinically important in the DLB group. CONCLUSION The findings of this study identify apathy as the most important NPS contributing to carer distress among carers of people with AD and DLB. These findings help us identify the support needs of families dealing with dementia.

Abstract
OBJECTIVES Sleeve gastrectomy (SG) is the most frequently performed bariatric surgery procedure worldwide, but reports on long-term quality of life (QOL) outcomes are scarce. We investigated 5-year trajectories in QOL and their associations with weight loss after SG. DESIGN A prospective cohort study. SETTING The study was conducted in a single Norwegian bariatric surgery centre. PARTICIPANTS Out of 150 operated patients, 127 were included. Mean age was 41 years, 68% were women and the follow-up rate at 1 year was 85% and 64% at 1 and 5 years, respectively. OUTCOME MEASURES Data were collected preoperatively, and 1 and 5 years after surgery assessing three different levels of QOL. The main exposure was weight loss after SG, assessed as per cent excess body mass index (kg/m2) loss (%EBMIL). The Obesity-Related Problem (OP) scale was used to measure obesity-specific health-related QOL (HRQOL). Physical (PCS) and mental (MCS) composite summary scores of the Short Form 36 Health Survey were used to capture generic HRQOL and Cantril Ladder was used to assess overall QOL. RESULTS All HRQOL/overall QOL measures significantly improved at 1 year, followed by modest decline from 1 to 5 years after surgery. Greater %EBMIL 5 years after surgery was significantly associated with improvements in OP and PCS scores, but not with MCS and Cantril Ladder scores. Although significant (p<0.001) and clinically relevant improvements in HRQOL/overall QOL outcomes were observed at 5 years, scores were still below the general population norms. CONCLUSION Most patients undergoing SG experience substantial weight loss accompanied by statistically significant and clinically relevant long-term improvements in HRQOL/overall QOL. However, an important minority of patients still report low HRQOL/overall QOL 5 years after SG. Further research should aim to identify other factors that contribute to impaired QOL after bariatric surgery, even in the presence of successful weight control.

Patient-reported quality of life with obesity - development of a new measurement scale. TIDSSKRIFT FOR DEN NORSKE LEGEFORENING 2019; 139:18-0493. [PMID: 31429227 DOI: 10.4045/tidsskr.18.0493] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND Many questionnaires for measuring the quality of life for patients with obesity require comprehensive calculation before they are used. There is a need for questionnaires that permit simple assessment of the responses during a patient consultation. We have developed the questionnaire Patient-Reported Outcomes in Obesity (PROS). The objective of the study was to test the reliability and validity of the questionnaire. MATERIAL AND METHOD The questionnaire was used to ask patients about the extent to which they perceived their weight or body shape as bothersome. A group of patients with an average body mass index (BMI) of 42 (n = 109) completed the PROS questionnaire and The Impact of Weight Quality of Life questionnaire (IWQOL-Lite) before undergoing obesity surgery. Another group with an average body mass index of 29 (n = 95) completed the PROS questionnaire 1-5 years after having undergone obesity surgery. 67,7 % of the patients were > 40 years and 79 % were women. For the statistical analysis we used Cronbach's alpha, factor analysis, Spearman's rank test and independent t-test. RESULTS Cronbach's alpha for the total PROS score was 0.90, and the factor analysis showed a significant factor (eigenvalue = 4.7) that explained 58.4 % of the variance. The test-retest correlation was 0.93 (p < 0.001). The correlation coefficients between the PROS score, the total IWQOL-Lite score (rs = -0.91) and body mass index (rs = 0.60) were all significant (p < 0.001). The t-test showed an effect size (difference in standard deviation) between the non-surgery and the surgery groups of 1.9 (95 % CI 1.6-2.5) for the PROS questionnaire and 2.1 (95 % CI 1.7-2.5 for the total IWQOL-Lite score. INTERPRETATION The PROS questionnaire is a reliable and valid questionnaire for measurement of obesity-specific quality of life.

Abstract
BACKGROUND Hand hygiene plays a vital role in the prevention of transmission of micro-organisms. Ozone (O3) is a highly reactive gas with a broad spectrum of antimicrobial effects on bacteria, viruses, and protozoa. It can easily be produced locally in small generators, and dissolved in tap water, and quickly transmits into ordinary O2 in the surrounding air. AIM To compare ozonized tap water and alcohol rub in decontamination of bacterially contaminated hands. METHODS A cross-over study among 30 nursing students. Hands were artificially contaminated with Escherichia coli (ATCC 25922), then sanitized with ozonized tap water (0.8 or 4 ppm) or 3 mL standard alcohol-based rub (Antibac 85%). The transient microbes from fingers were cultivated and colony-forming units (cfu)/mL were counted. The test procedure was modified from European Standard EN 1500:2013. FINDINGS All contaminated hands before disinfection showed cfu >30,000/mL. The mean (SD) bacterial counts in (cfu/mL) on both hands combined were 1017 (1391) after using ozonized water, and 2337 (4664) after alcohol hand disinfection. The median (range) values were 500 (0-6700) and 250 (0-16,000) respectively (non-significant difference). Twenty per cent of participants reported adverse skin effects (burning/dryness) from alcohol disinfection compared with no adverse sensations with ozone. CONCLUSION Ozonized tap water is an effective decontaminant of E. coli, and it could be an alternative to traditional alcohol-fluid hand disinfectants both in healthcare institutions and public places. Ozonized water may be especially valuable for individuals with skin problems.

Abstract
AIM This study investigated children's physical activity (PA) preferences, as these can aid the design of school-based interventions. METHODS Data were collected in 2014 as a part of the Active Smarter Kids study and 1026 students (52% boys) from 57 Norwegian primary schools completed a questionnaire about their favourite physical activities at a mean age of 10.2 ± 0.3 years. We identified five patterns of PA and studied whether gender, cardiorespiratory fitness and abdominal adiposity were associated with these patterns. RESULTS Soccer and slalom skiing were the favourite activities, and the most pronounced gender differences were for activities favoured by girls, which included dancing, gymnastics, exercising to music and jumping rope (p < 0.001). When the five component patterns were analysed using linear mixed-effect models, this showed a strong female preference for dancing, gymnastics, exercising to music and climbing. Cardiovascular fitness was negatively associated with frisbee, dodgeball, baseball and floorball, and positively associated with team handball, volleyball and basketball and with slalom skiing and cross-country skiing. It was interesting that the children's preferences were not related to their abdominal adiposity. CONCLUSION The results showed different gender-based PA preferences and positive and negative associations with cardiovascular fitness, but no relationship with abdominal adiposity.

Abstract
PURPOSE Losing weight and keeping it off for the long term is difficult. Weight regain is common. Experiences of successful non-surgical weight loss after severe obesity are largely unexplored. We know little about long-term weight loss processes, and how health care services can be of help to those living them. METHODS Drawing on in-depth interviews of 8 women and 2 men, the aim of this phenomenological study is to describe the experiences of adults who have been severely obese, who have lost weight and maintained weight loss for the long term (>5 years). RESULTS Findings show that after severe obesity, sustained weight loss has no endpoint, yet is always easy to end. Keeping weight off means committing to oneself, continuing profound changes and cultivating sensitivity towards oneself and others. A phenomenological understanding of sustained weight loss can inform professionals who deal with health issues and challenges occurring in the life of people leaving severe obesity.

A review of systematic reviews on the effects of patient-reported outcome monitoring with clinical feedback systems on health-related quality of life-implications for a novel technology in obesity treatment. Clin Obes 2018; 8:452-464. [PMID: 30208266 DOI: 10.1111/cob.12277] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 06/14/2018] [Accepted: 07/13/2018] [Indexed: 01/10/2023]
Abstract
Patient-reported outcome monitoring with clinical feedback systems (PRO/CFS) has been employed in many disease states to measure and improve health-related quality of life (HRQOL). Exploring the role of PRO/CFS in treatment for obesity may prove valuable. Systematic reviews were summarized to determine the effectiveness of PRO/CFS on HRQOL in any disease area. Primary studies evaluating the effect of PRO/CFS on HRQOL in treatment for obesity were also considered for inclusion. Systematic searches were performed in The Cochrane Library, PROSPERO, Epistemonikos, HTA, DARE, CINAHL, Medline, Embase, PsycINFO, BMJ Clinical Evidence, PDQ-Evidence and PubPsych. Two reviewers independently screened references until final inclusion and critically appraised included reviews using PRISMA checklist. Five systematic reviews and no primary studies met inclusion criteria. Although results were inconsistent, effectiveness of PRO/CFS on HRQOL was demonstrated in some diseases/treatments (e.g. psychiatric treatment; symptom burden in cancer treatment). No trials using PRO/CFS in treatment for obesity were identified. In some trials, PRO/CFS was not fully integrated into consultations, thereby PRO/CFS was not extensively studied. General effectiveness of PRO/CFS on HRQOL is inconclusive due to heterogeneous and statistically insignificant findings, and lack of stringency in conceptualization and execution of PRO/CFS. There are no data relevant to treatment for obesity. Future studies should use rigorous methodology to examine the effectiveness of PRO/CFS in treatment for obesity.

Abstract
We investigated whether a seven-month (November 2014 to June 2015), school-based cluster-randomized controlled physical activity intervention improved health-related quality of life (HRQoL) in 10-year old children. The participants (N = 1229) from 57 elementary schools in Sogn og Fjordane County, Norway, were cluster-randomized by school either to the intervention (I) or control (C) group. The planned intervention in the 28 I-schools was 300 min of physical activity per week, compared to 135 min in the 29C-schools. HRQoL was assessed by self-report, using the Kidscreen-27 questionnaire. Objectively measured physical activity did not differ between the I–schools and C-schools during the intervention. No effect of the intervention was found for HRQoL: Physical well-being (P = 0.789), Psychological well-being (P = 0.682), Autonomy & parents (P = 0.662), Social support & peers (P = 0.828) and School environment (P = 0.074). In conclusion, the ASK school-based physical activity intervention showed no significant effect on HRQoL.

Abstract
Demands made on nursing staff are expanding and changing, requiring a broad set of competencies that require evaluation and enhancement in places. This study used the Nurse Competence Scale to measure self-assessed competence among nurses working in three municipal health-care services in Norway. Results indicate that nurses perceive their competence as being satisfactory overall, but there are areas that would benefit from improvement: providing patients' family members with education and guidance, quality assurance, and using research to evaluate and develop services. These competencies could be the focus of departments' future competence plans. The Nurse Competence Scale can be used to assess the impact of training and the efficacy of competence-enhancing actions.

Prevalence of chronic compartment syndrome of the legs: Implications for clinical diagnostic criteria and therapy. Scand J Pain 2017; 12:7-12.

Abstract
INTRODUCTION Poorly defined musculoskeletal disorders are a common clinical problem and have considerable psychosocial impact. Chronic compartment syndrome (CCS) of the legs has primarily been noted in young athletes and soldiers. The epidemiology of CCS in the general population has not been studied previously. The aim of this study was to establish the prevalence of CCS of the legs in the general population and to study its association with possible etiological factors. METHODS A two-stage population survey was performed, using a questionnaire followed by clinical examination. A sample of 3000 individuals aged 25-75 years was randomly selected from the general population. A clinical examination was offered to those answering "Yes" to the following question: "Do you wake up at nights due to leg pains or cramps, causing you to walk around?" Intracompartmental pressures in the leg were measured in 13 persons randomly selected from among those diagnosed with CCS after the clinical examination. RESULTS Of the 3000 persons contacted, 2308 (76.9%) responders were included in the study. Leg pain or cramps at night was reported by 24% of the respondents. Age, rheumatic disease, use of hormone medication, heart failure, leg oedema, and peripheral arterial disease were all significantly associated with leg pain or cramps (P<0.05). Among 286 persons with leg pain who underwent a subsequent clinical examination, 91 persons (31.9%) were classified as definite CCS. This suggests a CCS prevalence of 7.6% in the total sample ([24%×31.9%/100]). In 13 of the individuals with CCS intracompartmental pressure was measured before and after performance of the step test exercise. One individual had a post-exercise pressure >15mmHg. None had post-exercise pressure past the conventional threshold of >30mmHg. CONCLUSION Nocturnal leg pain or cramps is a common symptom. A significant part of the general population (7.6%) may have CCS of the legs, with symptoms ranging from very mild to severe. IMPLICATIONS Considering the high prevalence of CCS found in this study, it is likely that a large proportion of those presenting with muscular pain actually have CCS. These persons are usually advised to increase their physical training to achieve some degree of pain relief. However, CCS patients may instead experience both increased leg pain and a proximal myalgia, which is possibly a referred pain. A demanding "gold standard" test (requiring identification of elevated of intracompartmental pressures), unclear diagnostic criteria, poor long-term results from incomplete surgery, and an uncertain explanation for what may be termed referred pain seem to have delayed the acceptance of CCS as a common cause of leg pain/cramps and numbness. At the same time, the enormous costs to society and the reduced quality of life of patients require that such disease entities are correctly diagnosed as they can be effectively treated by simple, low-risk surgical procedures.

Abstract
OBJECTIVE Neuropsychiatric symptoms (NPSs) are common in dementia, and they have been identified as important care-recipient variables in terms of their impact on caregiver burden. The aim of this review was to describe how individual NPSs in dementia, assessed using the Neuropsychiatric Inventory, are associated with caregiver burden. METHODS We performed a systematic review of English language, peer-reviewed articles retrieved from MEDLINE, PSYCINFO, and EMBASE. RESULTS A total of 13 studies met the inclusion criteria. Four studies examined the association between individual NPSs and caregiver burden using the Spearman rank correlation test, while three used Pearson's correlation test. Of the remaining studies, five used multiple regression analyses and one the chi-squared test. The majority of included studies did not differentiate between dementia subtypes in the analysis or mainly included only caregivers of people with Alzheimer's disease. The Clinical Dementia Rating score and mean Mini-Mental State Examination score indicate mild to moderate dementia. The majority of caregivers were women, most of whom were children (53.8%) or spouses (36%). The data indicated that irritability, followed by agitation, sleep disturbances, anxiety, apathy, and delusion seem to impact caregiver burden the most. CONCLUSION Our principal finding is that irritability, agitation, sleep disturbances, anxiety, apathy, and delusion seem to exert the most impact on caregiver burden. Heterogeneity in the measures and statistical analyses used, however, makes it difficult to make conclusive interpretations. Future research in this field would benefit from standardization of the scientific methodology in use. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
Osteoarthritis (OA) is the biggest unmet medical need among the many musculoskeletal conditions and the most common form of arthritis. It is a major cause of disability and impaired quality of life in the elderly. We review several ambitious but failed attempts to develop joint structure-modifying treatments for OA. Insights gleaned from these attempts suggest that these failures arose from unrealistic hypotheses, sub-optimal selection of patient populations or drug dose, and/or inadequate sensitivity of the trial endpoints. The long list of failures has prompted a paradigm shift in OA drug development with redirection of attention to: (1) consideration of the benefits of localized vs systemic pharmacological agents, as indicated by the increasing number of intra-articularly administered compounds entering clinical development; (2) recognition of OA as a complex disease with multiple phenotypes, that may each require somewhat different approaches for optimizing treatment; and (3) trial enhancements based on guidance regarding biomarkers provided by regulatory agencies, such as the Food and Drug Administration (FDA), that could be harnessed to help turn failures into successes.

Abstract
Ostomy-specific adjustment may or may not predict health-related quality of life (HRQoL) and/or overall quality of life (QoL). A cross-sectional study was conducted among patients recruited from the customer registers of 8 surgical suppliers and pharmacies across Norway between November 2010 and March 2011 to determine which of the 34 items of the Ostomy Adjustment Scale (OAS) are the strongest predictors for HRQoL and overall QoL and to determine the HRQoL and overall QoL of individuals with an ostomy compared to a control group representing the general population. Persons who were >18 years old; had a permanent colostomy, ileostomy, or urostomy for >3 months; and could read and write Norwegian were invited to participate. The participants received information about the study in a letter from the researcher and returned their demographic information (addressing gender, age, marital status, education, diagnosis, time since surgery, and ostomy type) and study questionnaires using prepaid envelopes. The 158 participants (mean age 64 years [range 29-91], 89 [56%] men and 69 [44%] women) completed and returned by mail a sociodemographic questionnaire, the 34-item OAS (questions scored on a scale of 1 to 6, totally disagree to totally agree, score range 34 to 204), the Short Form-36 (SF-36, including 2 main components [physical and mental issues] divided into 8 subscales, scored from 0 to 100), and the 16-item Quality of Life Scale (QOLS) instrument (each response scored 1 to 7, from very dissatisfied to very satisfied; total score ranging from 16 to 112). Statistical analysis, including ordinary least square regression analyses, assessed whether the OAS independently predicted the sum scores of the SF-36 (physical component summary [PCS] and mental component summary [MCS]) and the QOLS score after adjusting for age, gender, marital status, education, diagnosis, time since surgery, and ostomy type. The OAS significantly predicted the SF-36 (PCS and MCS) and QOLS scores (P <0.001). Five (5) OAS items ("living a fulfilling life," "being free to travel where I want despite my ostomy," "realizing that this ostomy will be there forever," "worries about being left alone," and "embarrassing accidents in sexual activities") strongly predicted the composite score of the SF-36 (PCS and MCS) and QOLS measurements. The SF-36 scores in physical role functioning, general health, vitality, and MCS were lower in ostomy patients than controls (P < 0.05), whereas no difference was found for QOLS. Overall, ostomy-specific adjustment may be an important predictor of HRQoL and overall QoL, with the OAS factors described above having greater influence. More research such as prospective cohort studies are needed regarding patient adjustment to an ostomy.

Intensive lifestyle intervention provides rapid reduction of serum fatty acid levels in women with severe obesity without lowering omega-3 to unhealthy levels. Clin Obes 2016; 6:259-67. [PMID: 27334055 PMCID: PMC5129509 DOI: 10.1111/cob.12151] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2016] [Revised: 04/24/2016] [Accepted: 05/06/2016] [Indexed: 11/29/2022]
Abstract
Serum fatty acid (FA) levels were monitored in women with severe obesity during intensive lifestyle intervention. At baseline, total FA levels and most individual FAs were elevated compared to a matching cohort of normal and overweight women (healthy controls). After 3 weeks of intensive lifestyle intervention, total level was only 11-12% higher than in the healthy controls and with almost all FAs being significantly lower than at baseline, but with levels of omega-3 being similar to the healthy controls. This is contrary to observations for patients subjected to bariatric surgery where omega-3 levels dropped to levels significantly lower than in the lifestyle patients and healthy controls. During the next 3 weeks of treatment, the FA levels in lifestyle patients were unchanged, while the weight loss continued at almost the same rate as in the first 3 weeks. Multivariate analysis revealed that weight loss and change of serum FA patterns were unrelated outcomes of the intervention for lifestyle patients. For bariatric patients, these processes were associated probably due to reduced dietary input and increased input from the patients' own fat deposits, causing a higher rate of weight loss and simultaneous reduction of the ratio of serum eicosapentaenoic to arachidonic acid.

Abstract
Background The Norwegian version of the Kidscreen-27, a measure of generic health-related quality of life, has not yet been validated. Thus, the aim of this study was to investigate the reliability and validity of the Norwegian Kidscreen-27, in 10 year-old children. Methods The Kidscreen-27 consists of five domains and was validated in a cross-sectional study of 1085 school children (52.5 % boys). In addition a subsample of 56 children also had repeated measures in order to study test-retest reliability. Results Cronbach's alpha values ranged from 0.73 to 0.83, while intraclass correlation values over time ranged from 0.71 to 0.81. The domains of physical well-being, psychological well-being and autonomy & parents improved over time (Ps < 0.05), while social support and school environment domains did not. Confirmatory factor analysis showed an acceptable overall model fit: X2 = 707; df = 310; P <0.001, root mean squared error of approximation = 0.037, the comparative fit index = 0.96 and the Tucker-Lewis index = 0.95. All factor loading were > 0.40. The Kidscreen-27 domains were significantly associated with general life satisfaction as measured with the Cantrils Ladder (Spearman rank correlations ranged from 0.29 to 0.59, Ps < 0.05). Conclusion The Norwegian version of Kidscreen-27 has good reliability and validity.

Abstract
Background. The aims of this study were to translate the Obesity-Related Problem scale (OP scale) into the Norwegian language and test its reliability, validity and responsiveness in a Norwegian sample. Method. The questionnaire (OP scale) was translated from the original language (Swedish) into Norwegian. Patients completed the questionnaire prior to and one year after sleeve gastrectomy. Internal consistency was evaluated using Cronbach's α. Construct validity was tested by correlating the OP-scale with the SF-36 and the Cantril Ladder using the Pearson correlation coefficient. An exploratory and confirmatory factor analysis was used to test the unidimensionality of the OP scale. Responsiveness was tested by assessing changes in the OP scale from baseline to one year post-surgery using the paired sample t-test. Floor and ceiling effect were calculated as percentages. Results. A total of 181 patients (123 women) accepted for bariatric surgery was included in the study. The mean age was 43.1 ± 12.5 years, and mean body mass index (BMI) before surgery was 45 ± 6.9. The mean value of the OP scale at baseline was 63.30 ± 24.43 (severe impairment) and 21.01 ± 20.98 at one year follow-up (mild impairment). Internal consistency was high at baseline (Cronbach's α 0.91). The floor effect was small at baseline and high at one year. The ceiling effect was small at baseline and at one year. Exploratory and conformatory factor analysis showed one factor with a high percent of explained variance. Correlations between OP scale at baseline, SF-36, Cantril Ladder and BMI were statistically significant and in the predicted direction to support validity of the Norwegian OP scale. After one year correlations between the change in OP scale and the change in SF-36 scores, Cantril Ladder and BMI were also statistically significant, except for the change in the Role Physical-scale. The OP scale showed greater responsiveness than either the SF-36 or Cantril Ladder. Conclusion. These results confirm that the Norwegian version of the OP scale is a valid and reliable instrument for measuring psychosocial functioning in patients with clinically severe obesity.

Employment status and sick-leave following obesity surgery: a five-year prospective cohort study. PeerJ 2015; 3:e1285.

Abstract
Background. Severe obesity is a risk factor for lower participation in paid work, but whether employment increases and sick leave decreases after obesity surgery is not well documented. Methods. We assessed 224 Norwegian patients with severe obesity (mean age: 40; mean BMI: 49; 61% female) regarding employment status (working versus not working) and the number of days of sick leave during the preceding 12 months, before and five years after obesity surgery (75% follow-up rate). Logistic regression analysis was used to study preoperative predictors of employment status after surgery. Results. There were no change in the employment rate over time (54% versus 58%), but the number of days of sick leave per year was significantly reduced, from a mean of 63 to a mean of 26, and from a median of 36 to a median of 4. Most of this change was attributable to patients with zero days of sick leave, which increased from 25% to 41%. Being female, older, having low education level, receiving disability pension and not being employed before obesity surgery were important risk factors for not being employed after obesity surgery. The type of obesity surgery, BMI and marital status were not useful predictors. Conclusions. Our findings suggest that undergoing obesity surgery is not associated with a higher rate of employment, although it may reduce the number of days of sick leave. Additional interventions are likely needed to influence the employment status of these patients. The significant preoperative predictors of not being employed in this study provide suggestions for further research.

OA phenotypes, rather than disease stage, drive structural progression--identification of structural progressors from 2 phase III randomized clinical studies with symptomatic knee OA. Osteoarthritis Cartilage 2015; 23:550-8. [PMID: 25576879 DOI: 10.1016/j.joca.2014.12.024] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2014] [Revised: 11/07/2014] [Accepted: 12/30/2014] [Indexed: 02/02/2023]
Abstract
BACKGROUND/PURPOSE The aim of this study was to identify key characteristics of disease progression through investigation of the association of radiographic progression over two years with baseline Joint Space Width (JSW), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain, Joint Space Narrowing (JSN), and BMI. METHODS Data from 2206 subjects (4390 knees) were combined for this post-hoc analysis of two randomized, double-blind, multi-center, placebo-controlled phase III trials (NCT00486434 and NCT00704847) that evaluated the efficacy and safety of 2-years treatment with oral salmon calcitonin of subjects with painful knee osteoarthritis (OA). RESULTS There was a clear positive and significant correlation between KL grade and WOMAC pain and total WOMAC, albeit the variance in pain measures was from min-to-max for all KL categories, emphasizing the heterogeneity of this patient population and pain perception. 32% of target knees did not progress, and only 51% had changes over minimum significant change (MSC). BMI, KL-Score and WOMAC pain was diagnostic, but only KL-score and pain had prognostic value, albeit pain in a non-linear manner. CONCLUSION These data clearly describe significant associations between KL grade, JSW, pain and BMI in patients with symptomatic knee OA. KL grade, BMI and WOMAC pain were diagnostically associated with OA based on JSW but only KL-score and pain in a non-linier fashion was prognostic. 50% of patients did not progress more than MSC, highlighting the importance for identification of structural progressors and the phenotypes associated with these. These results suggest that disease phenotypes, rather than disease status, are responsible for disease progression.

Abstract
It is unknown how changes in physical activity may affect changes in quality of life (QoL) outcomes during lifestyle interventions for severely obese adults. The purpose of this study was to examine associations in the patterns of change between objectively assessed physical activity as the independent variable and physical, mental, and obesity-specific QoL and life satisfaction as the dependent variables during a two-year lifestyle intervention. Forty-nine severely obese adults (37 women; 43.6 ± 9.4 years; body mass index 42.1 ± 6.0 kg/m(2)) participated in the study. Assessments were conducted four times using Medical Outcomes Study Short-Form 36 Health Survey (SF-36), Obesity-Related Problems (OP) scale, a single item on life satisfaction, and accelerometers. The physical component summary (PCS) score and the mental component summary (MCS) score were used as SF-36 outcomes. Associations were determined using linear regression analyses and reported as standardized coefficients (stand. coeff.). Change in physical activity was independently associated with change in PCS (stand. coeff. = 0.35, P = .033), MCS (stand. coeff. = 0.51, P = .001), OP (stand. coeff. = -0.31, P = .018), and life satisfaction (stand. coeff. = 0.39, P = .004) after adjustment for gender, age, and change in body mass index.

Abstract
BACKGROUND Direct measurement of physical activity may be critical to revealing its relationship with the change in fat mass over time. The aim of this study was to determine the relationship between accelerometer-determined change in physical activity and change in fat mass in severely obese men and women. METHODS A total of 49 severely obese men (n = 12) and women (n = 37) (mean age 42.8 years (standard deviation (SD) 9.6); mean body mass index 42.0 kg/m2 (SD 5.9) participated in a 1-year lifestyle intervention with 4 measurements of physical activity (Actigraph GT1M accelerometer), energy intake (180-item food frequency questionnaire), and body composition. Associations were determined using linear regression analyses. RESULTS In the total group change in both duration and intensity of physical activity were independently related to change in fat mass (partial r = -0.38 to -0.31, p = 0.001-0.007) after adjustment for baseline body weight, gender and change in energy intake. A gender-specific effect of change in physical activity duration was found for change in fat mass (p for change in physical activity duration*gender < 0.001), where the association was significant in men (partial r = -0.53, p < 0.001), but not in women (partial r = -0.17, p = 0.149). CONCLUSION Increased intensity of physical activity was associated with loss of fat mass in severely obese men and women, whereas physical activity duration was associated with fat mass loss in men.

Abstract
Background. Information on self-reported health is important for health professionals, and the aim of this study was to examine associations between lifestyle factors and self-reported health and the mediating effect of disease in a Norwegian population. Methods and Materials. The data collection was conducted as part of the Hordaland Health Study (HUSK) 1997–99, which was a cross-sectional epidemiological study. All individuals in Hordaland county born in 1953–1957 were invited to participate (aged 40–44 years). Complete information for the present study was obtained from 12,883 individuals (44% response rate). Height and weight were measured at a physical examination. Information on lifestyle factors, self-reported health, disease (heart attack, apoplexy, angina pectoris, and diabetes), and socio-demographic variables was obtained from a self-administered questionnaire. Self-reported health was measured with a one-item question. Odds ratios for fair or poor self-reported health were calculated using multiple logistic regression analyses adjusted for disease and socio-demographic variables. Results. Respondents reporting adverse lifestyle behaviours (obesity (odds ratio (OR) 1.7, p < 0.001), smoking (OR 1.2, p < 0.001), or excessive intake of alcohol (OR 3.3, p < 0.001)) showed an increased risk of poor self-reported health. Furthermore, a moderate intake of wine (OR 0.6, p < 0.001) or strenuous physical activity (OR 0.5, p < 0.001) decreased the risk of poor health. Disease did not mediate the effect. Conclusion. A one-item question measuring self-reported health may be a suitable measure for health professionals to identify levels of subjective health and reveal a need to target lifestyle factors in relatively young individuals with or without disease.

Abstract
Objective. This study of severely obese adults participating in a two-year lifestyle intervention investigates associations between the independent variables: change in self-efficacy for physical activity (PA) in the face of psychological barriers, perceived behavioural control over PA, and PA self-identity and the dependent variable of change in objectively assessed PA. The intervention comprised four residential periods in a rehabilitation centre and combined diet, physical activity, and cognitive behavioural therapy. Materials and Methods. Forty-nine severely obese adults (37 women, mean body mass index 42.1 kg/m2) were included in the study. Assessment was done four times using questionnaires and an accelerometer. A linear mixed model based on restricted maximum likelihood was used in analyses for change over time. Associations were studied using linear regression analyses. Age, gender, and change in body mass index were used as control variables. Results. In the adjusted analyses, change in perceived behavioural control over PA was associated with change in PA (Stand. coeff. = 0.32, p = .005). Change in PA was not associated with either change in self-efficacy over PA in the face of psychological barriers (Stand. coeff. = 0.13, p = .259) or PA self-identity (Stand. coeff. = −0.07, p = .538). Conclusion. Perceived behavioural control may be a valid target to increase and maintain PA in severely obese adults participating in lifestyle interventions. More research is needed to investigate the process of behaviour change in this population.

Abstract
Background Long-term data of health-related quality of life (HRQL) after biliopancreatic diversion with duodenal switch (BPDDS) procedure are lacking. The aim of this study was to evaluate changes in HRQL from baseline to 5 years after BPDDS. Methods Fifty morbidly obese patients were followed for 5 years after BPDDS procedure. The sample consisted of 27 women and 23 men, the mean age was 37.8 years, and the mean body mass index (BMI) was 51.7 units. HRQL was measured with the Short Form 36 questionnaire (SF-36). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS). Linear mixed model was used to investigate the change scores. The SF-36 scores and HADS scores of the sample were also compared with a Norwegian population norm, adjusted for age, gender, and BMI. Results Mental summary scores (MCS) and physical summary scores (PCS) were very low preoperatively but significantly improved (P < 0.05) 5 years after surgery. The PCS was comparable to the population norm, while MCS was lower. Depression improved significantly from baseline to the 5-year follow-up (P = 0.004), but anxiety did not (P = 0.595). Conclusions This study demonstrates a sustained weight loss and improved, although somewhat fading, HRQL scores 5 years after BPDDS. The study also shows that BPDDS is associated with a sustained reduction in depression symptoms but not in anxiety symptoms.

Abstract
BACKGROUND To evaluate changes in obesity-related diseases and micronutrients after laparoscopic sleeve gastrectomy (LSG). METHODS We started the procedure in May 2007, and by December 2011, 117 patients could be evaluated for a two year follow-up. Comparisons of preoperative status with 12 and 24 months postoperative status were made for body mass index (BMI), obesity-related diseases and micronutrients. RESULTS Major complications included bleeding requiring transfusion at 5.1%, leak at 1.7% and abscess without a visible leak at 0.9%. Mean BMI was reduced from 46.6 (standard deviation (SD) 6.0) kg/m2 to 30.6 (SD 5.6) kg/m2 at two years, and resolution occurred for 80.7% of patients with type 2 diabetes, 63.9% with hypertension, 75.8% with hyperlipidemia, 93.0% with sleep apnea, 31.4% with musculoskeletal pain, 85.4% with snoring and 73.3% with urinary incontinence. Amenorrhea resolved in all premenopausal females. The proportion of patients with symptomatic gastroesophageal reflux disease increased from 12.8% to 27.4%. The prevalence of patients with low ferritin-levels increased, while 25-hydroxyvitamin D (25(OH)D) deficiency decreased postoperatively. CONCLUSIONS LSG is an effective procedure for morbid obesity and obesity-related diseases, but the technique should be further explored particularly to avoid gastroesophageal reflux.

Impact of physical activity and diet on lipoprotein particle concentrations in severely obese women participating in a 1-year lifestyle intervention. Clin Obes 2013; 3:202-13. [PMID: 25586737 DOI: 10.1111/cob.12036] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2013] [Revised: 08/19/2013] [Accepted: 09/13/2013] [Indexed: 12/15/2022]
Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Physical activity and high aerobic fitness protects against cardiovascular disease and early death, besides having a very modest impact on lipoprotein-cholesterol in obese subjects. Physical activity has been shown to favourably alter lipoprotein particle concentrations and apolipoprotein B with minimal weight loss in overweight to moderately obese subjects. WHAT THIS STUDY ADDS We studied the impact of physical activity on lipoprotein subclass particle concentrations in women with severe obesity. Increased physical activity duration was associated with favourable changes, whereas increased PA intensity was associated with adverse changes in some lipoprotein particle subclasses in severely obese women. Severely obese women that manage to increase their physical activity level can improve their lipoprotein profile, whether or not they lose fat mass Physical activity (PA) and high aerobic fitness protects against cardiovascular disease and early death possibly among others because of an anti-atherogenic impact on lipoprotein particle concentrations. The objective of this study was to determine the impact of PA and diet on lipoprotein particle concentrations. Thirty-one severely obese women (age 43.6 ± 10.2 years; body mass index 43.0 ± 6.3 kg m(-2) ) participated in a 1-year lifestyle intervention with repeated measurements of lipoprotein particle subclass concentrations and size of very low density lipoprotein (VLDL), low density lipoprotein (LDL) and high density lipoprotein (HDL), as well as fat mass, PA and diet. Multiple regression was used to determine associations with change (Δ) in two principal components (PCs) describing lipoprotein distributions: ΔPC 1 LIPO (dominated by VLDL and LDL) and ΔPC 2 LIPO (dominated by large HDL and mean HDL particle size). ΔPA duration was the only variable that was significantly related to ΔPC 1 LIPO (partial r = -0.40, P = 0.008), while ΔPA intensity was the only variable that was significantly related to ΔPC 2 LIPO (partial r = -0.43, P = 0.003) in adjusted models. Increased PA duration was associated with favourable changes, whereas increased PA intensity was associated with adverse changes in some lipoprotein particle subclasses in severely obese women.

Increased physical activity improves aerobic fitness, but not functional walking capacity, in severely obese subjects participating in a lifestyle intervention. J Rehabil Med 2013; 45:1071-7.

Abstract
OBJECTIVE To determine the relationship between change in physical activity level and change in directly measured maximal aerobic fitness in severely obese subjects participating in a 1-year lifestyle intervention, and to determine whether change in 6-min walk test (6 MWT) could be used as an indicator of change in aerobic fitness. METHODS Complete data on aerobic fitness (maximal oxygen consumption (VO2max) and time to exhaustion on the VO2max test), 6 MWT, and physical activity (Actigraph GT1M accelerometer) were obtained for 21 subjects (mean age 42.6 years (standard deviation (SD) 11.0 years); mean body mass index 39.6 (SD 4.5) kg/m(2)). Multiple linear regression (controlling for change in body mass index) was used to analyse the relationships for: (i) changes in physical activity vs aerobic fitness and change in 6 MWT; and (ii) changes in aerobic fitness vs 6 MWT. RESULTS Change in physical activity level was related to VO2max and time to exhaustion (partial r > 0.63, p < 0.003). No significant relationships were found between changes in aerobic fitness and 6 MWT (partial r < 0.22, p > 0.351) or between changes in physical activity level and 6 MWT (partial r = 0.15, p = 0.531). CONCLUSION Increased physical activity level over 1 year resulted in increased aerobic fitness in severely obese subjects. Although the sample size was small, these results suggest that change in 6 MWT might not be a good indicator of maximal change in aerobic fitness in this population.

Evaluation of the efficacy, safety and pharmacokinetic profile of oral recombinant human parathyroid hormone [rhPTH(1-31)NH(2)] in postmenopausal women with osteoporosis. Bone 2013; 53:160-6. [PMID: 23234813 DOI: 10.1016/j.bone.2012.11.045] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2012] [Revised: 11/20/2012] [Accepted: 11/28/2012] [Indexed: 11/29/2022]
Abstract
CONTEXT Treatment of osteoporosis with subcutaneous (SC) injections of rhPTH(1-34) or rhPTH(1-84) is associated with significant improvements in BMD and reductions in osteoporotic fractures. However, subcutaneous injections can be associated with discomfort and thus deteriorating compliance. OBJECTIVE The UGL-OR1001 trial aimed to establish the efficacy and safety parameters of a novel oral tablet formulation of rhPTH(1-31)NH(2) and matching placebo tablets and open-label teriparatide positive control in postmenopausal women with osteoporosis. DESIGN 24 weeks of randomized, double-blind treatment with once daily doses of 5mg oral treatment or corresponding placebo, or open-label subcutaneous teriparatide. PATIENTS OR OTHER PARTICIPANTS Women diagnosed with postmenopausal osteoporosis as detected by lumbar spine DXA, with an exclusion of those with prior treatment with bone active agents. INTERVENTION(S) Orally formulated recombinant human PTH(1-31)NH(2) and placebo, or open-label subcutaneous teriparatide as a positive control. MAIN OUTCOME MEASURE(S) The primary endpoint was to characterize the percent change from baseline in bone mineral density (BMD) at L1-L4 axial lumbar spine after 24 weeks in the rhPTH(1-31)NH(2) arm. Secondary and exploratory endpoints included safety and tolerability of the oral formulation, measurement of biochemical markers of bone turnover, and evaluation of the PK profile at first and last dose. The study was registered at ClinicalTrials.gov with the identifier: NCT01321723. RESULTS The oral tablet formulation of rhPTH(1-31)NH(2) resulted in similar PK profiles at both timepoints with mean C(max) values similar to subcutaneous administration. In the rhPTH(1-31)NH(2) arm, a 2.2% increase in lumbar spine BMD was observed compared to baseline (p<0.001), while no change was observed in the placebo arm. Open-label teriparatide resulted in a 5.1% increase in LS BMD (p<0.001). In the oral PTH study arm, the bone formation marker osteocalcin was increased by 32%, 21% and 23% at Weeks 4, 12 and 24, respectively. There was no significant increase in the level of the bone resorption marker CTx-1. CONCLUSIONS In summary, these data demonstrate that enteric-coated oral tablet formulation technology consistently generated robust levels of exposure of rhPTH(1-31)NH(2) leading to induction of bone formation without inducing bone resorption resulting in significantly increased levels of LS BMD. Few adverse events were observed, recommending this orally delivered drug candidate for further development.

Development of technology for the early post mortem prediction of water holding capacity and drip loss in fresh pork. Meat Sci 2012; 55:115-22. [PMID: 22060911 DOI: 10.1016/s0309-1740(99)00133-3] [Citation(s) in RCA: 67] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/1999] [Revised: 09/07/1999] [Accepted: 09/30/1999] [Indexed: 11/25/2022]
Abstract
Two different technologies were tested on the slaughterline for their ability to predict drip loss at 24 h, namely near infrared reflectance (NIR) and impedance measurements using a tetra polar measuring geometry at a frequency of 1000 Hz. The results demonstrate that NIR measurements (900-1800 nm) acquired during a 6 min period starting only 30 min post exsanguination through a fibre optic probe in combination with multivariate data analysis can be used for predicting drip loss 24 h after slaughter. A correlation higher than 0.8 was observed for a trial on 99 carcasses measured at a commercial slaughterhouse. The tetrapolar impedance measurements did not perform as well as NIR yielding a correlation of 0.5 with 24 h drip loss.
