Project description:Single-leg squat (SLS) is a functional test visually rated by clinicians for assessing lower limb function as a preventive injury strategy. SLS clinical rating is a qualitative evaluation and it does not count objective outcomes as kinematics data and surface electromyography (sEMG) assessment. Based on the SLS rating, the aims of this study were (i) to determine the clinical rating agreement among six raters and (ii) to assess kinematic and sEMG predictors of good SLS performance in physically and non-physically active individuals.Seventy-two healthy adults, divided in physically active and non-physically active groups, performed three SLSs on their dominant leg. Clinical ratings, kinematic data and sEMG were acquired. By using a validated clinical scale, six expert clinicians rated each SLS watching a video at three different time points. Intra and inter-rater agreement of clinical ratings were undertaken and a binary logistic regression analysis was used to determine kinematic and sEMG as predictors of SLS performance.The weighted kappa coefficient for intra-rater reliability within each rater ranged between moderate and almost perfect agreement (0.55-0.85) whereas the weighted kappa coefficient for inter-rater reliability among raters was fair (0.34, time point 0; 0.31, time point 1; 0.30, time point 2). SLS analyses of physically active compared to non-physically active group showed a statistically significant difference in knee flexion and hip flexion (p = 0.041 and p = 0.023 respectively) and no difference in clinical ratings (p = 0.081). Greater knee flexion can predict the good SLS performance taking into account the belonging group (p = 0.019).Physically active individuals seemed to be at less risk to perform a non-good SLS and they had greater knee and hip flexions kinematics than non-physically active individuals. Knee flexion can predict the SLS performance quality therefore a greater knee flexion might also be considered a protective element from injuries.ClinicalTrials.gov identifier (trial has been registred retrospectively: NCT03203083.

Project description:BackgroundPhysical activity (PA) has been found to be an excellent predictor of mortality beyond traditional measures in COPD. We aimed to determine the association between depression and anxiety with accelerometry-based PA in patients with COPD.MethodsWe performed a cross-sectional analysis of baseline data from 148 stable patients with COPD enrolled in an ongoing, longitudinal, observational study. We measured PA (total daily step count) with a Stepwatch Activity Monitor over 7 days, depression and anxiety with the Hospital Anxiety and Depression Scales (HADSs), dyspnea with the Shortness of Breath Questionnaire, and functional capacity with the 6-min walk test.ResultsIncreased anxiety was associated with higher levels of PA such that for every one-point increase in the HADS-Anxiety score there was a corresponding increase of 288 step counts per day (β=288 steps, P<.001), after adjusting for all other variables. Higher levels of depressive symptoms were associated with lower PA (β=-176 steps, P=.02) only when anxiety was in the model. The interaction term for anxiety and depression approached significance (β=26, P=.10), suggesting that higher levels of anxiety mitigate the negative effects of depression on PA.ConclusionsThe increased PA associated with anxiety in COPD is, to our knowledge, a novel finding. However, it is unclear whether anxious patients with COPD are more restless, and use increased psychomotor activity as a coping mechanism, or whether those with COPD who push themselves to be more physically active experience more anxiety symptoms. Future studies should evaluate for anxiety and PA to better inform how to improve clinical outcomes.Trial registryClinicaltrials.gov; No.: NCT01074515; URL: www.clinicaltrials.gov.

Project description:Hypothesis: Gene expression differences in biopsies from patients with inflammatory bowel disease can be used to identify molecular heterogeneity within patients with active disease. Methods: Patients with a diagnosis of Crohn's disease, ulcerative colitis or normal healthy controls (with or without infectious colitis) underwent ileocolonoscopy. In healthy controls, biopsies were taken in the sigmoid colon (n=21), ascending/descending colon (n=25) and the terminal ileum (n=12). In patients with Crohn's disease, biopsies were taken in the ascending/descending colon (n=107) and terminal ileum (n=70) in uninflamed areas in all patients; in patients with mucosal lesions, additional biopsies were taken in inflamed regions of the ascending/descending colon (n=35) and terminal ileum (n=55). In ulcerative colitis patients, paired uninflamed sigmoid (n=48) and inflamed sigmoid biopsies (n=46) were taken. Biopsies were placed in RNAlater at the clinical site, frozen and shipped to Genentech, where they were disrupted using TissueLyzer beads, then RNA was isolated using RNeasy columns. RNA was hybridized to Agilent human 4x44kv1 arrays, dual channel, using universal reference.

Project description:BackgroundRegular physical activity had been shown to reduce morbidity and mortality from chronic diseases such as cardiovascular diseases, hypertension, type 2 diabetes mellitus, dyslipidaemia, obesity/metabolic syndrome, osteoarthritis, osteoporosis, bronchial asthma and chronic obstructive pulmonary disease. Research had shown that physically active doctors were more likely to offer exercise counselling to patients. However, few studies looked into this association with counselling practices to patients with specific chronic diseases. This study aims to determine the association between physical activity levels of primary care doctors (PCDs) in Malaysian private practice with physical activity counselling to patients with chronic diseases.MethodologyA cross-sectional study involving PCDs in private practice in 3 states was done. Participants were recruited from members of the Malaysian Academy of Family Physicians and attendees of a conference. A self-administered questionnaire obtained information on sociodemography, initiation of exercise counselling to patients with chronic diseases as well as physical activity levels using the International Physical Activity Questionnaire (IPAQ).ResultsThe response rate was 32.3% (272/842). 47.1% of the respondents were post-graduate holders. 50% of participants had a moderate level of physical activity and 24.3% a high level. Most respondents answered 'always' or 'often' for initiation of exercise counselling to patients with cardiovascular diseases (59.9%), hypertension (72.8%), type 2 diabetes mellitus (78.6%), obesity/metabolic syndrome (86.4%), dyslipidaemia (81.6%), osteoarthritis/osteoporosis (41.9%) and bronchial asthma/COPD (29.5%). PCDs being physically active and non-smokers were associated with a higher initiation of exercise counselling to patients with cardiovascular diseases. Doctors with post-graduate degrees were more likely to offer exercise counselling to hypertensive patients.ConclusionThe association between PCDs' physical activity levels and their physical activity counselling varies between different types of chronic diseases. Primary care doctors with higher physical activity levels were more likely to initiate physical activity counselling in patients with cardiovascular disease during chronic disease follow up visits.

Project description:Background: Hypertension is one of the most common metabolic diseases in the elderly and its pathogenesis is associated with microbiota dysbiosis. Recent evidence suggests that oral microbiota dysbiosis is also an important factor in the development of hypertension. However, the relationship between hypertension and oral flora in the elderly has not been adequately investigated. Objective: The aim of this cross-sectional study was to investigate the structure of the oral microbiota and its correlation with hypertension in elderly hypertensive patients. To provide new ideas for the prevention and treatment of hypertension. Methods: 206 subjects aged 60 ~ 89 years were selected and divided into normal (CON) and hypertensive (HTN) groups, according to the 2018 Chinese Guidelines for the Management of Hypertension. The oral microbiome composition of saliva samples was determined by 16S rRNA gene sequencing. Results: Although there was no significant difference in α and β diversity between the two groups, systolic and diastolic blood pressure were the most important factors influencing the structure of the oral microbiota. At the phylum level, the relative abundance of the spirochete phylum and the mutualistic bacterial phylum was higher in the HT group than in the CON group (p < 0.05). Diastolic blood pressure was negatively correlated with Streptococcus. Furthermore, we analyzed HTN patients with 120 mmHg<systolic blood pressure<160 mmHg and systolic blood pressure>160 mmHg separately and found that the abundance of Saccharibacteria_(TM7) was significantly increased in the HTN_2 group. Conclusions: Our study identified specific oral microbiota in elderly hypertensive patients, confirming the relationship between oral microbiota and hypertension. This enhances our understanding of the important role of oral microbiota in the pathogenesis of hypertension and accumulates more evidence for microbial involvement in the development of hypertension.

Project description:Improvement in health-related quality of life (HRQoL) is one of the main goals in treating chronic obstructive pulmonary disease (COPD). Impaired HRQoL in COPD is associated with increased morbidity and mortality, hospitalisations and burden on our health-care system. The Clinical COPD Questionnaire (CCQ) is a validated, reliable, short questionnaire for the evaluation of disease-specific HRQoL in patients with COPD in primary care.To investigate factors that might be associated with CCQ outcome in COPD in a primary care setting.In a population of COPD patients in primary care, multiple regression analyses were used to assess associations between CCQ outcome and depression, heart failure, FEV1% predicted, FEV1/FVC, age, sex, body mass index and current smoking.Data from 341 patients (mean age 68.1±10.3, COPD GOLD class I-III) were used for analyses. Together, heart failure and depression explained 23% of the variance in CCQ total score (P<0.001, N=93). Heart failure was most strongly associated with CCQ functional score (27% explained variance, P<0.001, N=100), whereas depression was most strongly associated with CCQ mental score (22% explained variance, P<0.001, N=93).CCQ outcomes are higher in COPD patients with heart failure and depression. These findings might imply that heart failure and depression affect HRQoL of patients with COPD, and thus emphasise the importance of a holistic approach of this complex disease, leading to a correct diagnosis of COPD and its comorbidities, to achieve better tailored treatment of chronic patients.

Project description:Effectiveness of technology-based interventions to improve physical activity (PA) in people with COPD is controversial. Mixed results may be due to participants' characteristics influencing their use of and engagement with mobile health apps. This study compared demographic, clinical, physical and PA characteristics of patients with COPD using and not using mobile apps in daily life. Patients with COPD who used smartphones were asked about their sociodemographic and clinic characteristics, PA habits and use of mobile apps (general and PA-related). Participants performed a six-minute walk test (6MWT), gait speed test and wore an accelerometer for 7 days. Data were compared between participants using (App Users) and not using (Non-App Users) mobile apps. A sub-analysis was conducted comparing characteristics of PA-App Users and Non-Users. 59 participants were enrolled (73% Male; 66.3 ± 8.3 yrs; FEV1 48.7 ± 18.4% predicted): 59% were App Users and 25% were PA-App Users. Significant differences between App Users and Non-App Users were found for age (64.2 ± 8.9 vs. 69.2 ± 6.3yrs), 6MWT (462.9 ± 91.7 vs. 414.9 ± 82.3 m), Gait Speed (Median 1.5 [Q1-Q3: 1.4-1.8] vs. 2.0 [1.0-1.5]m/s), Time in Vigorous PA (0.6 [0.2-2.8] vs. 0.14 [0.1-0.7]min) and Self-Reported PA (4.0 [1.0-4.0] vs. 1.0 [0.0-4.0] Points). Differences between PA-App Users and Non-Users were found in time in sedentary behavior (764.1 [641.8-819.8] vs. 672.2 [581.2-749.4] min) and self-reported PA (4.0 [2.0-6.0] vs. 2.0 [0.0-4.0] points). People with COPD using mobile apps were younger and had higher physical capacity than their peers not using mobile apps. PA-App Users spent more time in sedentary behaviors than Non-Users although self-reporting more time in PA.

Project description:BackgroundCardiovascular disease, osteoporosis and emphysema are associated with COPD. Associations between these factors and whether they predict all-cause mortality in COPD patients are not well understood. Therefore, we examined associations between markers of cardiovascular disease (coronary artery calcification [CAC], thoracic aortic calcification [TAC] and arterial stiffness), bone density (bone attenuation of the thoracic vertebrae), emphysema (PI-950 and 15th percentile) and all-cause mortality in a COPD cohort.MethodsWe assessed CAC, TAC, bone attenuation of the thoracic vertebrae, PI-950 and 15th percentile on low-dose chest computed tomography in COPD subjects. We measured arterial stiffness as carotid-radial pulse wave velocity (PWV), and identified deaths from the national register.ResultsWe studied 119 COPD subjects; aged 67.8 ±7.3, 66% were males and mean FEV1% predicted was 46.0 ±17.5. Subjects were classified into three pre-specificed groups: CAC = 0 (n = 14), 0 < CAC ≤ 400 (n = 41) and CAC > 400 (n = 64). Subjects with higher CAC were more likely to be older (p < 0.001) and male (p = 0.03), and more likely to have higher systolic blood pressure (p = 0.001) and a history of hypertension (p = 0.002) or ischemic heart disease (p = 0.003). Higher CAC was associated with higher PWV (OR 1.62, p = 0.04) and lower bone attenuation (OR 0.32, p = 0.02), but not with 15th percentile, after adjustment for age, sex and pack-years of smoking. In a Cox proportional hazards model, CAC, TAC and 15th percentile predicted all-cause mortality (HR 2.01, 2.09 and 0.66, respectively).ConclusionsIncreased CAC was associated with increased arterial stiffness and lower bone density in a COPD cohort. In addition, CAC, TAC and extent of emphysema predicted all-cause mortality.Trial registrationLothian NHS Board, Lothian Research Ethics Committee, LREC/2003/8/28.

Project description:BackgroundThe group assignment of chronic obstructive pulmonary disease (COPD) may differ depending on whether the COPD assessment test (CAT) or modified Medical Research Council dyspnoea scale (mMRC) is used.AimsThis study intended to clarify how different patient characteristics influence the differences, to determine the relationships between CAT and mMRC and to characterise COPD patients by both CAT and mMRC.MethodsThis was a retrospective, cross-sectional study. The data, collected by Taiwan Obstructive Lung Disease consortium, were managed and analysed.ResultsOf the 757 participants, COPD group assignment was not identical as well as no substantial agreement presented when categorised based on the cut-point CAT score ⩾10 and each mMRC cut-point. In all, 38.2% of participants had discordant group assignments together with a lower mean CAT score, less severe airway obstruction and less severe airflow limitation compared with those with concordant group assignments. In the discordant group, the CAT⩾10/mMRC 0-1 subgroup had more wheezing than CAT<10/mMRC⩾2 subgroup. Only moderate correlations existed between CAT and mMRC. More-symptom groups and combined high-risk group had better correlations than less-symptom groups and combined low-risk group, respectively. A modest negative correlation existed between forced expiratory volume in 1 s percentage (FEV1%) predicted and CAT score and between FEV1% predicted and mMRC scale in parallel with a significant positive relationship existing between the CAT score and mMRC scale. Notably, a significant proportion of COPD patients with each scale of mMRC had health status impairment.ConclusionsThe Global initiative for Chronic Obstructive Lung Disease committee should redefine the applications of CAT and mMRC in the management of COPD.

Project description:Genetic and environmental risk factors contribute to periodontal disease, but the underlying susceptibility pathways are not fully understood. Epigenetic mechanisms are malleable regulators of gene function that can change in response to genetic and environmental stimuli, thereby providing a potential mechanism mediating risk effects in periodontitis. The aim of this study is to identify epigenetic changes across tissues that are associated with periodontal disease.
