- Declining systolic blood pressure (SBP) is common in very old age and is associated with adverse events, such as dementia. Knowledge of factors associated with SBP changes could explain the etiology of this decline in SBP. This study investigated longitudinal changes in socioeconomic factors, medical conditions, drug prescriptions, and assessments and their associations with SBP changes among very old followed individuals.The study was based on data from the Umea85+/Gerontological Regional Database (GERDA) cohort study, which provided cross-sectional and longitudinal data on participants aged 85, 90, and 95 years from 2000 to 2015. Follow-up assessments were conducted after 5 years. The main outcome was a change in SBP. Factors associated with SBP changes were assessed using multivariate linear regression models.In the Umea85+/GERDA study, 454 surviving individuals underwent follow-up assessment after 5 years. Of these, 297 had SBP measured at baseline and follow-up. The mean changestandard deviation in SBP was -12 +/- 25mm Hg. SBP decline was associated independently with later investigation year (P=.009), higher baseline SBP (P<.001), baseline antidepressant prescription (P=.011), incident acute myocardial infarction during follow-up (P=.003), new diuretic prescription during follow-up (P=.044), and a decline in the Barthel Activities of Daily Living index at follow-up (P<.001).In conclusion, SBP declines among very old individuals. This decline seems to be associated with initial SBP level, investigation year, and health-related factors.

- There is a need for tailored exercise recommendations to patients with Myasthenia Gravis (MG). A few pilot studies have recently shown that physical exercise in accordance with general recommendations to healthy adults can be applied safely to patients with mild MG symptoms. How physical exercise affects muscle parameters and risk factors for life-style diseases in patients with MG is, however, only poorly known. We evaluated functional skeletal muscle parameters in 11 MG patients, before and after conducting a 12-week supervised physical therapy regimen of aerobic and high-resistance strength training. After the training program, parameters of the proximal leg muscle rectus femoris improved: compound motor action potential (from 4.5 ± 2.6 to 5.3 ± 2.8 mV, p=0.016), isometric muscle force (from 25.2 ± 4.4 to 30.2 ± 3.8 kg; p=0.014) and ultrasound muscle thickness (from 19.6 ± 5.6 to 23.0 ± 3.9 mm, p=0.0098) all increased. Further, physical performance-based measures improved, including the 30-Second Chair Stand Test (median change +2, p=0.0039) as well as the clinical MG composite score (from 3[2-5] to 2 [0-4], p=0.043). These findings indicate that MG patients can improve their functional muscle status as a result of aerobic and high-resistance strength training, especially in proximal leg muscles. This is important knowledge when physical therapy is considered for this patient group, for whom no guidelines on physical exercise currently exist.

- The expression of abnormal microRNA (miRNA, miR) is a ubiquitous feature of colorectal cancer (CRC). The pathological features and clinical behaviors of synchronous CRC have been comprehensively described; however, the expression profile of miRNA and small nucleolar RNA (snoRNA) in synchronous CRC has not been elucidated. In the present study, the expression profile of miRNA and snoRNA in 5 synchronous CRCs, along with the matched normal colorectal tissue was evaluated by microarray. Function and pathway analyses of putative targets, predicted from miRNA-mRNA interaction, were performed. Moreover, we analyzed clinicopathological and molecular characteristics of 22 patients with synchronous CRC and 579 solitary CRCs in a retrospective cohort study. We found a global dysregulation of miRNAs, including an oncogenic miR-17-92 cluster and oncosuppressive miR-143-145 cluster, and snoRNAs in synchronous CRC. Differential miRNA rather than snoRNA expression was robust enough to distinguish synchronous cancer from normal mucosa. Function analysis of putative targets suggested that miRNA clusters may modulate multiple effectors of oncogenic pathways involved in the pathogenesis of synchronous CRC. A comparison of normal mucosa between synchronous and solitary CRC suggested a differential genetic background of synchronous CRC from solitary CRC during carcinogenesis. Compared with solitary cancer patients, synchronous cases exhibited multiple extra-colonic cancers (P=0.012), coexistence of adenoma (P=0.012), microsatellite instability (P=0.024), and less glucose transporter 1 (P=0.037). Aberrant miRNA expression profiles could potentially be used as a diagnostic tool for synchronous CRC. Our findings represent the first comprehensive miRNA and snoRNA expression signatures for synchronous CRC, implicating that the miRNAs and snoRNAs may present therapeutic targets for synchronous CRC.

- Adverse events (AEs) occur in health care and may result in harm to patients especially in the field of surgery. Our objective was to analyze AEs in surgical patient care from a nationwide perspective and to analyze the frequency of AEs that may be preventable. In total 19,141 randomly selected admissions in 63 Swedish hospitals were reviewed each month during 2013 using a 2-stage record review method based on the identification of predefined triggers. The subgroup of 3301 surgical admissions was analyzed. All AEs were categorized according to site, type, level of severity, and degree of preventability. We reviewed 3301 patients' records and 507 (15.4%) were associated with AEs. A total of 62.5% of the AEs were considered probably preventable, over half contributed to prolonged hospital care or readmission, and 4.7% to permanent harm or death. Healthcare acquired infections composed of more than one third of AEs. The majority of the most serious AEs composed of healthcare acquired infections and surgical or other invasive AEs. The incidence of AEs was 13% in patients 18 to 64 years old and 17% in >= 65 years. Pressure sores and drug-related AEs were more common in patients being >= 65 years. Urinary retention and pressure sores showed the highest degree of preventability. Patients with probably preventable AEs had in median 7.1 days longer hospital stay. We conclude that AEs are common in surgical care and the majority are probably preventable.

- Background: To investigate the effect of neck-specific exercise with (NSEB) or without (NSE) a behavioural approach and prescribed physical activity (PPA) on general pain disability and psychological factors in chronic whiplash-Associated disorders (WAD), grade 2 and 3, with a 2-year follow-up. Methods:A randomized controlled multi-centre study of 3 exercise interventions (NSE, NSEB or PPA) including a 2-year follow-up. A total of 216 volunteers with chronic WAD were recruited and 194 were analyzed, mean age 40.4 (Standard Deviation [SD] 11.4). Measures of general pain disability, pain catastrophizing, anxiety and depression, and kinesiophobia were evaluated at baseline, and 3, 6, 12 and 24 months with linear mixed models. Results: General pain disability decreased by 28% in the NSEB group from baseline to 3 months (P<0.001) and the improvements in disability were maintained over time (6, 12 and 24 months P<0.01) compared to the NSE (P>0.42) and PPA groups (P>0.43). Pain catastrophizing decreased in the NSE group from baseline to 6 and 12 months (P<0.01) and in the NSEB group from baseline to 3 and 24 months (P<0.01) compared to the PPA group (P>0.82) that showed no change over time. The NSE group improved in kinesiophobia over time from baseline to12 months (P<0.01) compared to the NSEB (P=0.052) and the PPA groups (P>0.74). Anxiety decreased over time from baseline to 12 and 24 months in the NSE group (P>0.02), but not in the NSEB (P>0.25) or the PPA (P>0.50) groups. The PPA had no effect on general disability or any of the measured psychological factors. Conclusion: This randomised controlled trial with a 2-year follow-up shows that physiotherapist-led neck-specific exercise with or without the addition of a behavioural approach had superior outcome on general disability and most psychological factors compared to the mere prescription of physical activity.

- Mucinous adenocarcinoma (MC) is a special histology subtype of colorectal adenocarcinoma. The survival of MC is controversial and the prognostic biomarkers of MC remain unclear. To analyze prognostic significance and molecular features of colorectal MC. This study included 755,682 and 1001 colorectal cancer (CRC) patients from Surveillance, Epidemiology, and End Results program (SEER, 1973 2011), and Linkoping Cancer (LC, 1972-2009) databases. We investigated independently the clinicopathological characteristics, survival, and variety of molecular features from these 2 databases. MC was found in 9.3% and 9.8% patients in SEER and LC, respectively. MC was more frequently localized in the right colon compared with nonmucinous adenocarcinoma (NMC) in both SEER (57.7% vs 37.2%, P < 0.001) and LC (46.9% vs 27.7%, P < 0.001). Colorectal MC patients had significantly worse cancer-specific survival (CSS) than NMC patients (SEER, P < 0.001; LC, P = 0.026), prominently in stage III (SEER, P < 0.001; P=0.023). The multivariate survival analysis showed that MC was independently related to poor prognosis in rectal cancer patients (SEER, hazard ratios [HR], 1.076; 95% confidence intervals [CI], 1.057-1.096; P < 0.001). In LC, the integrated analysis of genetic and epigenetic features showed that that strong expression of PINCH (HR, 3.954; 95% CI, 1.493-10.47; P = 0.013) and weak expression of RAD50 (HR 0.348, 95% CT, 0.106-1.192; P=0.026) were significantly associated with poor CSS of colorectal MC patients. In conclusion, the colorectal MC patients had significantly worse CSS than NMC patients, prominently in stage III. MC was an independent prognostic factor associated with worse survival in rectal cancer patients. The PINCH and RAD50 were prognostic biomarkers for colorectal MC patients.

Tidskriftsartikel (refereegranskat)abstract
- Autoimmune hepatitis (AIH) is a chronic autoimmune liver disease that if left untreated may lead to the development of cirrhosis. Previous studies on AIH patients have suggested that fibrosis and even cirrhosis can be reversed by medical treatment. The aim of this study was to evaluate the efficacy of medical treatment for protection of developing fibrosis and cirrhosis.A total of 258 liver biopsies from 101 patients (72 women, 29 men) were analyzed by a single pathologist and classified according to the Ishak grading (inflammation) and staging (fibrosis) system. Liver histology was stratified according to the temporal changes of fibrosis stage (increased, decreased, or stable), and groups were compared.Complete or partial response to medical treatment was 94.9%. Reduction of fibrosis stage from the first to the last biopsy was seen in 63 patients (62.4%). We found an association between a reduction in the fibrosis stage and continuous glucocorticoid medication, as well as lowered scores of inflammation at last biopsy. Twenty-one patients had cirrhosis (Ishak stage 6) at least in one of the previous biopsies, but only 5 patients at the last biopsy.Histological improvement is common in AIH patients that respond to medical treatment, and a reduction or stabilization of fibrosis stage occurs in about 2/3 of such patients.

- This cross-sectional study investigates the plasma inflammatory profile of chronic widespread pain CWP) patients compared to healthy controls CON). Rather than analyzing a relatively few substances at a time, we used a new multiplex proximity extension assay PEA) panel that enabled the simultaneous analysis of 92 inflammation-related proteins, mainly cytokines and chemokines. Seventeen women with CWP and 21 female CON participated and a venous blood sample was drawn from all subjects. Pain intensity and pain thresholds for pressure, heat, and cold were registered. A PEA panel 92 proteins) was used to analyze the blood samples. Multivariate data analysis by projection was used in the statistical analyses. Eleven proteins significantly differentiated the CON and CWP subjects R-2=0.58, Q(2)=0.37, analysis of variance of cross-validated predictive residuals P=0.006). It was not possible to significantly regress pain thresholds within each group CON or CWP). Positive significant correlations existed between several proteins and pain intensities in CWP, but the model reliability of the regression was poor. CWP was associated with systemic low-grade inflammation. Larger studies are needed to confirm the results and to investigate which alterations are condition-specific and which are common across chronic pain conditions. The presence of inflammation could promote the spreading of pain, a hallmark sign of CWP. As it has been suggested that prevalent comorbidities to pain (e.g., depression and anxiety, poor sleep, and tiredness) also are associated with inflammation, it will be important to determine whether inflammation may be a common mediator.

- The evidence concerning how posture influences blood pressure is not consistent. The aim of this cross-sectional study was to consider the clinical and epidemiological implications of blood pressure measured in seated versus supine position, and to investigate the impact of age, sex, body mass index (BMI), and diabetes on these differences. This study included 1298 individuals (mean age 58.6 +/- 11.8 years) from the Vara-Skovde cohort at the 10 years' follow-up visit in 2014. Physical examination included blood pressure measurements in seated and supine position. Self-reported information on diabetes status, hypertension, ongoing medication, leisure time physical activity, and smoking habits were obtained. Linear regression models accounted for differences in age, sex, BMI, and known diabetes. Both systolic and diastolic blood pressure were significantly higher in the seated position [1.2mm Hg, P<.001, 95% confidence interval (95% CI) 0.79-1.54 and 4.2mm Hg, P<.001, 95% CI 4.08-4.71, respectively]. The prevalence of high blood pressure in seated position was higher (19.9%) than in supine position (13.5%). Linear regression analysis showed that age (beta=-0.215, P<.001) and diabetes (beta=-0.072, P=.012) were associated with smaller differences in postural diastolic blood pressure and BMI (beta=0.124, P<.001) with greater difference. This study showed substantial postural differences in blood pressures measured in office. Measuring blood pressure in the supine position shows lower blood pressure readings when compared with the seated position. Clinicians should be aware of how age, BMI, and diabetes influence these differences.

- The aim was to study persistence to, and switching between, antihypertensive drug classes and to determine factors associated with poor persistence.This was an observational cohort study. The Swedish Primary Care Cardiovascular Database includes data from medical records, socioeconomic data, filled prescriptions, and hospitalizations from national registries for 75,000 patients with hypertension. Patients included in the study were initiated on antihypertensive drug treatment in primary healthcare in 2006 to 2007. We defined class persistence as the proportion remaining on the initial drug class, including 30 days of gap. Patients with a filled prescription of another antihypertensive drug class after discontinuation of the initial drug, including 30 days of gap, were classified as switchers. Persistence to the various drug classes were compared with that for diuretics.We identified 4997 patients (mean age 6012 years in men and 63 +/- 13 years in women). Out of these, 95 (2%) filled their first prescription for fixed combination therapy and 4902 (98%) for monotherapy, including angiotensin converting enzyme inhibitors (37%), angiotensin receptor blockers (4%), beta blockers (21%), calcium channel blockers (8%), and diuretics (28%). Persistence to the initial drug class was 57% after 1 year and 43% after 2 years. There were no differences in persistence between diuretics and any of the other antihypertensive drug classes, after adjustment for confounders. Discontinuation (all adjusted) was more common in men (P=0.004), younger patients (P<0.001), those with mild systolic blood pressure elevation (P<0.001), and patients born outside the Nordic countries (P<0.001). Among 1295 patients who switched drug class after their first prescription, only 21% had a blood pressure recorded before the switch occurred; and out them 69% still had high blood pressures.In conclusion, there appears to be no difference in drug class persistence between diuretics and other major antihypertensive drug classes, when factors known to be associated with poor persistence are taken into account.
