Prevalence of osteoporosis and osteopenia in stable patients of chronic obstructive pulmonary disease in Sub-Himalayan region of Himachal Pradesh, India

Factors associated with patellofemoral pain in recreational road cyclists: A cross-sectional study in 59953 cyclists - SAFER XXXIII

OBJECTIVE

Patellofemoral pain (PFP) is a common cycling-related injury, and independent factors need to be identified to enable effective injury prevention strategies. We aim to determine factors associated with PFP in cyclists entering mass community-based events.

DESIGN

Cross-sectional study.

SETTING

2016-2020 Cape Town Cycle Tour.

PARTICIPANTS

Consenting race entrants.

MAIN OUTCOME MEASURES

62758 consenting race entrants completed a pre-race medical questionnaire, and 323 reported PFP. Selected factors associated with PFP (demographics, cycling experience and training, chronic disease history) were explored using multivariate analyses.

RESULTS

Prevalence ratio (PR) of PFP was similar for sex and age groups. Independent factors associated with PFP (adjusted for sex and age) were history of chronic disease [Composite Chronic Disease Score (0-10)(PR = 2.0, p < 0.0001) and any allergies (PR = 2.0, p < 0.0001)].

CONCLUSION

A history of chronic diseases and allergies is associated with PFP in cyclists. Practical clinical recommendations are: 1) that prevention programs for PFP be considered when cycling is prescribed as a physical activity intervention for patients with chronic disease, and 2) that older cyclists presenting with PFP be assessed for the presence of risk factors or existing chronic disease.

Lower Prevalence of Osteoporosis in Patients with COPD Taking Anti-Inflammatory Compounds for the Treatment of Diabetes: Results from COSYCONET

Background

Patients with chronic obstructive pulmonary disease (COPD) often have osteoporosis and diabetes as comorbid conditions. Anti-diabetic medication, including metformin, has protective effects on osteoporosis in experimental studies. We therefore studied whether patients with COPD receiving anti-diabetic medication had a lower osteoporosis prevalence in a large COPD cohort, COSYCONET.

Methods

Assessment of osteoporosis was based on patients’ reports of physician-based diagnoses and the presence of disease-specific medication. The predictive value of physical characteristics, lung function, comorbidities, cardiovascular medication, and the use of anti-inflammatory diabetes medication, including metformin, sulfonylureas, glinides or DPP4I, was evaluated using logistic regression analysis. ClinicalTrials.gov: NCT01245933.

Results

In total, 2222 patients were eligible for analysis (863 [39%] female, mean age 65 y), 515 of whom had higher symptoms and exacerbations (Global Initiative for Chronic Obstructive Lung Disease group D). Osteoporosis was present in 15.8% of the overall cohort, and in 24.1% of GOLD D patients. Regression analyses identified the following as associated with osteoporosis (p < 0.05): female sex, higher age, lower body-mass index, asthma, higher air trapping, oral steroids, and cardiovascular medication. Although oral anti-diabetic medication was overall not associated with a lower prevalence of osteoporosis (p = 0.131), anti-inflammatory anti-diabetic medication (p = 0.009) and metformin-containing therapy (p = 0.039) were. This was driven by GOLD D patients.

Conclusion

In a large COPD cohort, anti-inflammatory diabetes therapy, including metformin, was associated with a lower prevalence of osteoporosis, especially in patients with higher symptoms and exacerbations. These findings suggest a protective effect of common anti-diabetic medication on osteoporosis, possibly as a result of attenuated systemic inflammation.

Virtual Reality Technology Combined with Comprehensive Pulmonary Rehabilitation on Patients with Stable Chronic Obstructive Pulmonary Disease

With the popularization of medical knowledge and the development of medical technology, people pay more and more attention to COPD. This paper mainly studies the effect of virtual reality technology combined with comprehensive lung rehabilitation on patients with stable chronic obstructive pulmonary disease. 60 patients with stable chronic obstructive pulmonary disease were selected to collect their general information, such as name, gender, and age. They were divided into the experimental group and control group, 30 patients in each group. The experimental group was treated with virtual reality technology combined with lung rehabilitation, while the control group was treated with conventional rehabilitation. Patients in both groups needed medication and participated in a 30-minute disease description activity once a week. In addition, patients in the control group should walk for 20 minutes every day to monitor muscle fatigue. Breathing exercises are also carried out regularly. Patients are instructed to use their lips and abdomen for 5 minutes each time. The respiratory rate was 7 beats per minute. In addition to the routine training of the control group, the experimental group will also train the simulated bicycle for 20 minutes, which will be automatically saved on the computer after the training. After the experiment, the muscle function and motor ability of the two groups were evaluated, and the results were statistically analyzed. The total self-efficacy scores of patients before and after telemedicine technical support increased significantly (2.15 ± 0.21 before telemedicine technical support, 2.39 ± 0.20 after telemedicine technical support), and the difference was statistically significant (P < 0.05). The results show that the application of virtual reality technology can improve the rehabilitation belief of patients and strengthen the training effect.

Independent Risk Factors Predicting Gradual Onset Injury in 2824 Trail Running Race Entrants: SAFER XVIII Study

INTRODUCTION

Trail running is characterized by elevation changes, with uneven and varying running surfaces. Risk factors that may predict gradual-onset running-related injuries (GORRIs) in short-distance trail running have not been explored. The objective was to determine risk factors that predict GORRIs in trail running race entrants who entered mass community-based trail running events.

METHODS

In this descriptive cross-sectional study, data were collected prospectively from a prerace medical screening questionnaire over 4 trail run events held annually. Using a Poisson regression model, runner demographics, race distance, running training/racing variables, history of chronic diseases (number of chronic diseases reported as a cumulative "chronic disease composite score"), and allergies were investigated to determine factors predicting self-reported GORRI history in the previous 12 mo.

RESULTS

This study included 2824 race entrants (80% of entrants). The retrospective annual incidence for GORRIs was 13%. Independent risk factors predicting GORRIs were longer race distance (P<0.0001), increasing chronic disease composite score (P=0.0012), and a history of allergies (P=0.0056). The lower limb (94%) was the main anatomic region of GORRIs, and soft tissue injuries accounted for most (83%) GORRIs. Common specific GORRIs were iliotibial band syndrome (22%), Achilles tendon injury (10%), and hamstring injury (9%).

CONCLUSIONS

Independent risk factors predicting GORRIs among trail running entrants included longer race distance, a higher chronic disease composite score, and a history of allergies. This study has highlighted trail running race entrants at risk for sustaining GORRIs who could be targeted for future injury prevention interventions.

Association of COPD with osteoporosis in male smokers: A case control study in a tertiary medical college hospital in Bangladesh

OBJECTIVES

Chronic obstructive pulmonary disease (COPD) may increase the risk of osteoporosis and resulting fractures can contribute to disability and mortality of patients. We intended to evaluate the frequency of osteoporosis in male smokers with and without COPD and study whether any correlation existed between osteoporosis and COPD.

MATERIALS AND METHODS

This case-control study was carried out in the Department of Medicine, Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh between July 2013 and June 2015. Seventy four male smokers with COPD and 66 age-matched male smokers without COPD were enrolled. All individuals underwent Bone Mass Densitometry (BMD) by Dual-Energy X-Ray Absorptiometry (DEXA).

RESULTS

COPD and non-COPD groups did not differ regarding age and smoking pack-years. Osteoporosis at femoral neck (48.6% versus 16.7%; p< 0.001) and lumbar spine (68.9% versus 37.9%; p< 0.01) was significantly higher in COPD compared to controls. Osteopenia did not differ significantly. Patients with COPD were 4.5 times more likely to develop osteoporosis than controls after adjusting age, smoking-pack years and BMI (adjusted OR = 4.5; 95% CI = 1.8-11.5).

CONCLUSIONS

Osteoporosis is more frequent in male smokers with COPD compared to smokers without COPD. COPD is a risk factor of osteoporosis independent of age, smoking and BMI.

Osteoporosis among Patients with Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-analysis of Prevalence, Severity, and Therapeutic Outcomes

Chronic obstructive pulmonary disease (COPD) can be associated with systemic inflammatory trademarks and can coexist with other chronic debilitating diseases such as osteoporosis, which is considered among the most serious comorbidities of COPD. In this review, we aimed at finding answers for the following questions and tried to encapsulate the available literature: (1) how prevalent is osteoporosis among patients with COPD? (2) What are severity patterns of osteoporosis in case of COPD? (3) What are the therapeutic outcomes for patients with osteoporotic COPD? The total number of patients with COPD from all studies was 3815, majority of which were male (2658) representing 69.67% of patients. The mean ± standard deviation for percentage of forced expiratory volume in 1s (FEV1%) was 55.43 ± 14.62%, body mass index for almost 91.29% of patients was 24.4 ± 4.45 kg/m², whereas fat-free mass index (FFMI) was 17 ± 0.93 kg/m² for 17.66%. The percentage of patients with COPD having osteoporosis varied in the analyzed studies from 14% up to 66.6%. The mean prevalence of reported osteopenia from 14 studies (n = 2107) was 39.91%, whereas for osteoporosis, the mean prevalence was 37.62% for all included studies. Osteoporosis was highly prevalent among patients with COPD. It is reasonable to call for osteoporosis screening in patients with COPD who are above 65 years, in advanced stages, with BMI lower than 21 kg/m² or with FFMI lower than 16 kg/m² for males and 15 kg/m² for females. There is a lack of research investigating severity and treatments of osteoporosis in patients with COPD.
