Gender perspective on older people’s exercise preferences and motivators in the context of falls prevention: a qualitative study

Background: Several factors have previously been identified to positively influence the uptake and adherence for fall prevention exercise programmes. There is, however, a lack of studies investigating if men and women differ in their views and preferences for fall prevention exercises. Aim: To explore exercise preferences and motivators of older community-dwelling women and men in the context of falls prevention from a gender perspective. Methods: Workshops including multistage focus group discussions were conducted with 18 older community-dwelling people with and without history of falls. Participants were purposively selected and divided into two groups. Each group met on six occasions over a period of five months. Participatory and Appreciative Action and Reflection methodology was used to guide the discussions. A qualitative content analysis approach was used in the analysis. Results: Older participants had many diverse preferences and confirmed that individually tailored exercise, in terms of mode, intensity, challenge, and social context, is important. Moreover, important factors for exercise adherence and maintenance included the experience of individual confirmation; different spirit lifters to increase enjoyment; and personal tricks to maintain exercise routines. The individual differences within genders were more diverse than the differences between women and men. Conclusion: Exercise interventions to prevent falls should be individually tailored, based on the specific needs and preferences of the older participant, and do not appear to require gender specific approaches. To increase adherence, intrinsic motivation for exercise may be encouraged by competence enhancing confirmations, energizing spirit lifters, and practical tips for exercise maintenance. The study provides an awareness about women's and men's preferences for fall prevention exercises, and this information could be used as guidance in designing inclusive exercise interventions

Wood in psychiatric in-patient rooms may reduce the length of stay for patients

Objective – To outline a study of healthcare outcomes for psychiatric patients within an in-patient psychiatric ward. The planned study was initiated as a follow-up of the design process, where emphasis was made to use interior surfaces of wood in a new Swedish psychiatric building. Background –The influence of the physical environment for treatment outcomes within somatic care has been acknowledge for decades. Today there is also a growing amount of research within the field of psychiatric health facilities. View of, and access to, nature have shown to be of major importance. Recent research suggests that wood in patient rooms may have a healing effect. Research question – Does the use of wood in psychiatric in-patient rooms have positive health outcomes, such as reduced length of stay for patients and reduced stress levels? Method – The quantitative study will be executed in a new Swedish psychiatric building with 96 in-patient rooms in 4 wards. Each ward is divided into modules (6 patients/module). The study has a comparative approach: treatment outcomes in a module where patient rooms with wood covered facade-walls (n=2) will be compared to rooms with painted plaster façade-walls (n=2) and artificial wood panels (n=2). Patients in the module, intended for a special but general diagnosis, will be placed randomly in rooms with or without wood surfaces. All patient rooms are én-suite rooms. The staff is identical between rooms. All patient rooms have identical orientation. Results – An outline of a study in a psychiatric hospital is presented. This includes aspects related to research design, participation from patients, ethical considerations and statistical power of the planned experiment. Final outcomes from the study will be carried out after the new psychiatric building is inaugurated in 2020. Conclusion – Choice of building material can be an important measure to include in the design of health facilities. The study will provide new insights into what materials can be used and how they should be used to maximise possible beneficial health effects. Several aspects of architectural design can influence users in the built environment. Thus, there can be confounding factors influencing patients´ health and psychological well-being.publishedVersio

Preoperative biomarkers related to inflammation may identify high-risk anastomoses in colorectal cancer surgery : explorative study

Anastomotic leakage is a major complication after colorectal surgery, presumed to correspond with a process of failed wound healing, involving inflammation. Circulating levels of inflammation-related biomarkers were investigated in preoperative samples from 41 patients with leakage, who had elective treatment with a primary anastomosis for non-disseminated colorectal cancer, matched to 41 complication-free controls. A total of 15 inflammation-related proteins were elevated before surgery in patients with rectal cancer with leakage, of which C-X-C motif chemokine 6 and C-C motif chemokine 11 remained significantly increased after controlling for multiplicity. As a corresponding expression pattern difference did not emerge when tissue adjacent to the anastomosis was evaluated with immunohistochemistry, findings may reflect a systemic rather than a local host response. While these findings require validation before implementation into surgical practice, they highlight the need for further translational investigations as a promising research area to help decrease leakage rates. Background Colorectal anastomotic leakage can be considered a process of failed wound healing, for which related biomarkers might be a promising research area to decrease leak rates. Methods Patients who had elective surgery with a primary anastomosis for non-metastatic colorectal cancer, at two university hospitals between 1 January 2010 and 31 December 2015 were included. Patients with an anastomotic leak were identified and matched (1:1) to complication-free controls on the basis of sex, age, tumour stage, tumour location, and operating hospital. Preoperative blood samples were analysed by use of protein panels associated with systemic or enteric inflammation by proteomics, and enzyme-linked immunosorbent assays. Multivariable projection methods were used in the statistical analyses and adjusted for multiple comparisons to reduce false positivity. Rectal cancer tissue samples were evaluated with immunohistochemistry to determine local expression of biomarkers that differed significantly between cases and controls. Results Out of 726 patients undergoing resection, 41 patients with anastomotic leakage were matched to 41 controls. Patients with rectal cancer with leakage displayed significantly elevated serum levels of 15 proteins related to inflammation. After controlling for a false discovery rate, levels of C-X-C motif chemokine 6 (CXCL6) and C-C motif chemokine 11 (CCL11) remained significant. In patients with colonic cancer with leakage, levels of high-sensitivity C-reactive protein (hs-CRP) were increased before surgery. Local expression of CXCL6 and CCL11, and their receptors, were similar in rectal tissues between cases and controls. Conclusion Patients with anastomotic leakage could have an upregulated inflammatory response before surgery, as expressed by elevated serological levels of CXCL6 and CCL11 for rectal cancer and hs-CRP levels in patients with colonic cancer respectively. Preoperative inflammation-related serum proteins were evaluated in a case-control study of 41 patients with anastomotic leakage matched 1:1 with 41 complication-free controls. The chemokines C-X-C motif chemokine 6 and C-C motif chemokine 11 were significantly increased before surgery in patients with rectal cancer and leakage, a finding requiring further validation.Peer reviewe

Circulating Tissue Polypeptide-Specific Antigen in Pre-Diagnostic Pancreatic Cancer Samples

Simple Summary:& nbsp;Detecting cancer early significantly increases the chances of successful (surgical) treatment. Pancreatic cancer is one of the deadliest cancer forms, since it is usually discovered at a late and already spread stage. Finding biomarkers showing pancreatic cancer at an early stage is a possible approach to early detection and improved treatment. The aim of our study was to assess the potential of tissue polypeptide specific antigen (TPS) as a biomarker for early pancreatic cancer detection. We studied TPS levels in blood plasma samples from a population-based biobank in Vasterbotten, Sweden that were collected before individuals were diagnosed with pancreatic cancer. Although TPS levels are raised at diagnosis, this occurs late, and thus TPS does not seem to hold promise as an early detection marker for pancreatic cancer.& nbsp;Early detection of pancreatic ductal adenocarcinoma (PDAC) is challenging, and late diagnosis partly explains the low 5-year survival. Novel and sensitive biomarkers are needed to enable early PDAC detection and improve patient outcomes. Tissue polypeptide specific antigen (TPS) has been studied as a biomarker in PDAC diagnostics, and it has previously been shown to reflect clinical status better than the 'golden standard' biomarker carbohydrate antigen 19-9 (CA 19-9) that is most widely used in the clinical setting. In this cross-sectional case-control study using pre-diagnostic plasma samples, we aim to evaluate the potential of TPS as a biomarker for early PDAC detection. Furthermore, in a subset of individuals with multiple samples available at different time points before diagnosis, a longitudinal analysis was used. We assessed plasma TPS levels using enzyme-linked immunosorbent assay (ELISA) in 267 pre-diagnostic PDAC plasma samples taken up to 18.8 years before clinical PDAC diagnosis and in 320 matched healthy controls. TPS levels were also assessed in 25 samples at PDAC diagnosis. Circulating TPS levels were low both in pre-diagnostic samples of future PDAC patients and in healthy controls, whereas TPS levels at PDAC diagnosis were significantly increased (odds ratio 1.03; 95% confidence interval: 1.01-1.05) in a logistic regression model adjusted for age. In conclusion, TPS levels increase late in PDAC progression and hold no potential as a biomarker for early detection.Peer reviewe

Gender perspectives on views and preferences of older people on exercise to prevent falls: a systematic mixed studies review

Background: To offer fall prevention exercise programs that attract older people of both sexes there is a need to understand both womens and mens views and preferences regarding these programs. This paper aims to systematically review the literature to explore any underlying gender perspectives or gender interpretations on older peoples views or preferences regarding uptake and adherence to exercise to prevent falls. Methods: A review of the literature was carried out using a convergent qualitative design based on systematic searches of seven electronic databases (PubMed, CINAHL, Amed, PsycINFO, Scopus, PEDro, and OTseeker). Two investigators identified eligible studies. Each included article was read by at least two authors independently to extract data into tables. Views and preferences reported were coded and summarized in themes of facilitators and barriers using a thematic analysis approach. Results: Nine hundred and nine unique studies were identified. Twenty five studies met the criteria for inclusion. Only five of these contained a gender analysis of mens and womens views on fall prevention exercises. The results suggests that both women and men see women as more receptive to and in more need of fall prevention messages. The synthesis from all 25 studies identified six themes illustrating facilitators and six themes describing barriers for older people either starting or adhering to fall prevention exercise. The facilitators were: support from professionals or family; social interaction; perceived benefits; a supportive exercise context; feelings of commitment; and having fun. Barriers were: practical issues; concerns about exercise; unawareness; reduced health status; lack of support; and lack of interest. Considerably more women than men were included in the studies. Conclusion: Although there is plenty of information on the facilitators and barriers to falls prevention exercise in older people, there is a distinct lack of studies investigating differences or similarities in older womens and mens views regarding fall prevention exercise. In order to ensure that fall prevention exercise is appealing to both sexes and that the inclusion of both men and women are encouraged, more research is needed to find out whether gender differences exists and whether practitioners need to offer a range of opportunities and support strategies to attract both women and men to falls prevention exercise.Funding Agencies|Swedish Research Council [2015-03481]; Strategic Research Programme in Care Sciences, Umea University; Karolinska Institute, Sweden; Umea University</p

Lipopolysaccharide Diversity Evolving in Helicobacter pylori Communities through Genetic Modifications in Fucosyltransferases

Helicobacter pylori persistently colonizes the gastric mucosa of half the human population. It is one of the most genetically diverse bacterial organisms and subvariants are continuously emerging within an H. pylori population. In this study we characterized a number of single-colony isolates from H. pylori communities in various environmental settings, namely persistent human gastric infection, in vitro bacterial subcultures on agar medium, and experimental in vivo infection in mice. The lipopolysaccharide (LPS) O-antigen chain revealed considerable phenotypic diversity between individual cells in the studied bacterial communities, as demonstrated by size variable O-antigen chains and different levels of Lewis glycosylation. Absence of high-molecular-weight O-antigen chains was notable in a number of experimentally passaged isolates in vitro and in vivo. This phenotype was not evident in bacteria obtained from a human gastric biopsy, where all cells expressed high-molecular-weight O-antigen chains, which thus may be the preferred phenotype for H. pylori colonizing human gastric mucosa. Genotypic variability was monitored in the two genes encoding α1,3-fucosyltransferases, futA and futB, that are involved in Lewis antigen expression. Genetic modifications that could be attributable to recombination events within and between the two genes were commonly detected and created a diversity, which together with phase variation, contributed to divergent LPS expression. Our data suggest that the surrounding environment imposes a selective pressure on H. pylori to express certain LPS phenotypes. Thus, the milieu in a host will select for bacterial variants with particular characteristics that facilitate adaptation and survival in the gastric mucosa of that individual, and will shape the bacterial community structure

Reproductive factors and epithelial ovarian cancer survival in the EPIC cohort study

Background: Reproductive factors influence the risk of developing epithelial ovarian cancer (EOC), but little is known about their association with survival. We tested whether prediagnostic reproductive factors influenced EOC-specific survival among 1025 invasive EOC cases identified in the European Prospective Investigation into Cancer and Nutrition (EPIC) study, which included 521 330 total participants (approximately 370 000 women) aged 25–70 years at recruitment from 1992 to 2000. Methods: Information on reproductive characteristics was collected at recruitment. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), and multivariable models were adjusted for age and year of diagnosis, body mass index, tumour stage, smoking status and stratified by study centre. Results: After a mean follow-up of 3.6 years (±3.2 s.d.) following EOC diagnosis, 511 (49.9%) of the 1025 women died from EOC. We observed a suggestive survival advantage in menopausal hormone therapy (MHT) users (ever vs never use, HR=0.80, 95% CI=0.62–1.03) and a significant survival benefit in long-term MHT users (⩾5 years use vs never use, HR=0.70, 95% CI=0.50–0.99, Ptrend=0.04). We observed similar results for MHT use when restricting to serous cases. Other reproductive factors, including parity, breastfeeding, oral contraceptive use and age at menarche or menopause, were not associated with EOC-specific mortality risk. Conclusions: Further studies are warranted to investigate the possible improvement in EOC survival in MHT users

Enhancing rare variant interpretation in inherited arrhythmias through quantitative analysis of consortium disease cohorts and population controls.

PURPOSE: Stringent variant interpretation guidelines can lead to high rates of variants of uncertain significance (VUS) for genetically heterogeneous disease like long QT syndrome (LQTS) and Brugada syndrome (BrS). Quantitative and disease-specific customization of American College of Medical Genetics and Genomics/Association for Molecular Pathology (ACMG/AMP) guidelines can address this false negative rate. METHODS: We compared rare variant frequencies from 1847 LQTS (KCNQ1/KCNH2/SCN5A) and 3335 BrS (SCN5A) cases from the International LQTS/BrS Genetics Consortia to population-specific gnomAD data and developed disease-specific criteria for ACMG/AMP evidence classes-rarity (PM2/BS1 rules) and case enrichment of individual (PS4) and domain-specific (PM1) variants. RESULTS: Rare SCN5A variant prevalence differed between European (20.8%) and Japanese (8.9%) BrS patients (p = 5.7 × 10-18) and diagnosis with spontaneous (28.7%) versus induced (15.8%) Brugada type 1 electrocardiogram (ECG) (p = 1.3 × 10-13). Ion channel transmembrane regions and specific N-terminus (KCNH2) and C-terminus (KCNQ1/KCNH2) domains were characterized by high enrichment of case variants and >95% probability of pathogenicity. Applying the customized rules, 17.4% of European BrS and 74.8% of European LQTS cases had (likely) pathogenic variants, compared with estimated diagnostic yields (case excess over gnomAD) of 19.2%/82.1%, reducing VUS prevalence to close to background rare variant frequency. CONCLUSION: Large case-control data sets enable quantitative implementation of ACMG/AMP guidelines and increased sensitivity for inherited arrhythmia genetic testing

Organizing Language Interpreting Services in Elderly and Emergency Healthcare

With an increasing migrant population there is a growing need to organize interpreting practices in healthcare in order to deliver equitable high-quality care. This thesis focuses on healthcare institutions’ organization of interpreting services. The aim of the study was to explore interpreting practices in a healthcare context by comparing two different healthcare areas – elderly and emergency healthcare. The study aimed to highlight the impact of the organizational and institutional context. This study was designed as an explorative and descriptive qualitative study including 79 healthcare professionals with experience of interpreting practices recruited via purposeful sampling in elderly and emergency healthcare. Data were collected through individual and focus-group interviews and analysed with inductive qualitative content analysis. The main findings show that the processes and structures around interpreting practices were complex and mainly linked to individual and interpersonal levels and, to a limited extent, to the institutional level. On the institutional level the Public Procurement Act was the only formal policy to follow. On individual and interpersonal level interpreting practices were structured by self-established informal workplace routines developed by the professional groups. The norms and routines used was determined by access to interpreters, time aspects, characteristics of the care given, health conditions and the person’s problem, expectations and requests from the person and also from healthcare professionals. There were wishes for improvement, with better flexibility in access to professional interpreters, training for users and interpreters, and also better technical solutions and equipment. In conclusion, the use of interpreters was rooted in the organizational environment of interpreting practice, including the availability of laws, policy and guidelines, and closely related to individuals’ language skills, cultural values and social factors. The use of professional interpreters was based on the nature of care in context and access to interpreters and determined by health professionals’ estimation of the person’s current health status in order to deliver fast and individualized care based on humanistic values. Thus, it is important to consider organizational framework and cultural awareness when formulating interpreting practices adapted to the context, and formal guidelines in order to achieve the aim of personcentered and equal health care
