- Introduction: (Neo-)adjuvant chemotherapy for breast cancer has a deleterious impact on muscle tissue resulting in reduced cardiorespiratory fitness, skeletal muscle mass and function. Physical exercise during treatment may counteract some of these negative effects. However, the effects of resistance training (RT) alone have never been explored. The present study aims to investigate if heavy-load RT during (neo-)adjuvant chemotherapy counteracts deleterious effects on skeletal muscle in women diagnosed with breast cancer. We hypothesize that (neo-)adjuvant treatment with chemotherapy will reduce muscle fiber size, impair mitochondrial function, and increase indicators of cellular stress and that RT during treatment will counteract these negative effects. We also hypothesize that RT during (neo-)adjuvant chemotherapy will increase muscle and blood levels of potential antitumor myokines and reduce treatment-related side effects on muscle strength and cardiorespiratory fitness. Methods: Fifty women recently diagnosed with breast cancer scheduled to start (neo-)adjuvant chemotherapy will be randomized to either randomized to either intervention group or to control group. The intervention group will perform supervised heavy-load RT twice a week over the course of chemotherapy (approximately 16-weeks) whereas the control group will be encouraged to continue with their usual activities. Muscle biopsies from m. vastus lateralis will be collected before the first cycle of chemotherapy (T0), after chemotherapy (T1), and 6 months later (T2) for assessment of muscle cellular outcomes. The primary outcome for this study is muscle fiber size. Secondary outcomes are: regulators of muscle fiber size and function, indicators of cellular stress and mitochondrial function, myokines with potential antitumor effects, muscle strength, and cardiorespiratory fitness. Ethics and dissemination: Ethical approval has been obtained from the Regional Ethical Review Board in Uppsala, Sweden (Dnr:2016/230/2). Results will be disseminated through presentations at scientific meetings, publications in peer-reviewed journals, social media, and patient organizations.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: This study protocol describes the Fex-Can Childhood project, comprising two studies: The Fex-Can Childhood observational study (OS) and the Fex-Can Childhood randomized controlled trial (RCT). The Fex-Can Childhood OS aims to determine the prevalence and predictors of sexual dysfunction and fertility-related distress in young adult childhood cancer survivors (aged 19-40) compared to an age matched comparison group; the Fex-Can Childhood RCT will evaluate the effect of a web-based psycho-educational intervention (Fex-Can intervention) on sexual dysfunction and fertility-related distress. Methods: The Fex-Can Childhood OS will have a population-based cross-sectional design. All individuals treated for childhood cancer in Sweden at the age of 0 to 17 years (current age 19-40) will be identified through the National Quality Registry for Childhood Cancer. Established self-reported instruments will be used to measure sexual function, fertility-related distress, body image, anxiety and depression, and health-related quality of life. Self-efficacy related to sexual function and fertility, and fertility-related knowledge, will be assessed by study-specific measures. Clinical variables will be collected from the registry. Results will be compared to an age-matched comparison group from the general population. Participants in the Fex-Can Childhood OS who report a high level of sexual dysfunction and/or fertility-related distress will be invited to participate in the RCT. The Fex-Can intervention comprises two programs: The Fex-Can Sex and the Fex-Can Fertility targeting sexual dysfunction and fertility-related distress, respectively. The control condition will be a wait-list. Sexual function and fertility-related distress will be the primary outcomes. The secondary outcomes include body image, anxiety and depression, health-related quality of life and self-efficacy related to sexual function and fertility. Post- and follow-up assessments will be conducted directly after end of intervention (primary end point), at 3 months and 6 months after end of intervention. Additionally, a process-evaluation including study-specific items and a qualitative interview will be conducted. Discussion: The Fex-Can Childhood project will advance knowledge in the areas of sexual function and fertility-related distress among young adult survivors of childhood cancer. If the Fex-Can intervention proves to be efficacious, steps will be taken to implement it in the follow-up care provided to this population.

- 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.

- Diagnosis of viral meningitis (VM) is uncommon practice in Sudan and there is no local viral etiological map. We therefore intended to differentiate VM using standardized clinical codes and determine the involvement of herpes simplex virus types-1 and 2 (HSV-1/2), varicella zoster virus, non-polio human enteroviruses (HEVs), and human parechoviruses in meningeal infections in children in Sudan. This is a cross-sectional hospital-based study. Viral meningitis was differentiated in 503 suspected febrile attendee of Omdurman Hospital for Children following the criteria listed in the Clinical Case Definition for Aseptic/Viral Meningitis. Patients were children age 0 to 15 years. Viral nucleic acids (DNA/RNA) were extracted from cerebrospinal fluid (CSF) specimens using QIAamp® UltraSens Virus Technology. Complementary DNA was prepared from viral RNA using GoScriptTM Reverse Transcription System. Viral nucleic acids were amplified and detected using quantitative TaqMan® Real-Time and conventional polymerase chain reactions (PCRs). Hospital diagnosis of VM was assigned to 0%, when clinical codes were applied; we considered 3.2% as having VM among the total study population and as 40% among those with proven infectious meningitis. Two (0.4%) out of total 503 CSF specimens were positive for HSV-1; Ct values were 37.05 and 39.10 and virus copies were 652/PCR run (261 × 103/mL CSF) and 123/PCR run (49.3 × 103/mL CSF), respectively. Other 2 (0.4%) CSF specimens were positive for non-polio HEVs; Ct values were 37.70 and 38.30, and the approximate virus copies were 5E2/PCR run (~2E5/mL CSF) and 2E2/PCR run (~8E4/mL CSF), respectively. No genetic materials were detected for HSV-2, varicella zoster virus, and human parechoviruses. The diagnosis of VM was never assigned by the hospital despite fulfilling the clinical case definition. Virus detection rate was 10% among cases with proven infectious meningitis. Detected viruses were HSV-1 and non-polio HEVs. Positive virus PCRs in CSFs with normal cellular counts were seen.
