Introduction: Mycobacteria pulmonary diseases are chronic illnesses with various impacts on patients’ health status, and wellbeing. These diseases currently represent a global health issue due to increasing burdens and the lack of new development on therapeutic options. Policies based on the quality of life may help to improve the management of this chronic respiratory disease; this study was designed to assess the quality of life of patients treated for the pulmonary mycobacterial disease. Materials and Methods: Participants diagnosed with a mycobacterial pulmonary disease were selected from the University Clinical Research Centers’ (UCRC) 2019 mycobacterial cohort database. A telephone interview was conducted using the Medical Outcome Study Short Form (SF-36) which has 36 items evaluating physical and mental wellbeing. Scores range from 0 - 100, with higher scores indicating greater Healthrelated quality of life (HRQOL). Statistical analysis was performed with SPSS 23.0 and the Fisher test was used to compare percentages. A p-value less than 0.05 was considered significant. Results: A total of 26 participants were reached and interviewed by phone. The mean age was 42 ± 10.6 years, and 76.9% (20/26) were male. The most common cause of the mycobacterial pulmonary disease was Mycobacterium tuberculosis , with 84.6% (22/26). Four cases of Non-Tuberculous Mycobacteria (NTM) were diagnosed including one Mycobacterium avium complex strain (MAC). HIV-positive cases were 46.2% (12/26), and the main respiratory sign was cough for all the participants (100%), followed by dyspnea 46.2% (12/26), chest pain 38.5% (10/26). The mean BMI was 19.7 ± 6.9 kg/m2, the mean respiratory rate was 24.7 ± 8.6, and the mean hemoglobin was 11.8 ± 2.2 g/dl. The mean SF-36 score was 75.1 ± 16.6, and impairment was mainly related to mental problems in 59.6%. The mean total score was significantly lower with age more than 42 years than age less than 42 years. But HIV positive and BMI less than 18.5 do not lead to a significant change of mean total score. Conclusion: Patients with mycobacterial pulmonary diseases have more psychological problems than physical ones. Hence the importance of psychological support in their management to improve their quality of life. A large sample size with a deep interview component would be necessary to address limitations in this design....
Background: Bronchial thermoplasty (BT) is an effective treatment in severe asthma. How to select patients who more likely benefit from BT is an unmet clinical need. Moreover, mechanisms of BT efficacy are still largely unknown. We sought to determine BT efficacy and to identify potential mechanisms of response. Methods: This retrospective cohort study evaluated clinical outcomes in 27 patients with severe asthma: 13 with T2-high and 14 with T2-low endotype. Expression levels of 20 genes were compared by real-time PCR in bronchial biopsies performed at the third BT session versus baseline. Clinical response was measured based on Asthma Control Questionnaire (ACQ) score < 1.5, asthma exacerbations < 2, oral corticosteroids reduction of at least 50% at 12 months post-BT. Patients were classified as responders when they had at least 2 of 3 outcome measures. Results: 81% of patients were defined as responders. BT induced a reduction in alpha smooth muscle actin (ACTA2) and an increase in CD68, fibroblast activation protein-alpha (FAP), alpha-1 and alpha-2 type I collagen (COL1A1, COL1A2) gene expression in the majority of patients. A higher reduction in ubiquitin carboxy-terminal-hydrolase L1 (PGP9.5) mRNA correlated with a better response based on Asthma Quality of Life Questionnaire (AQLQ). Lower changes in CD68 and FAP mRNAs correlated with a better response based on ACQ. Lower levels of occludin (OCLN), CD68, connective tissue growth factor (CTGF), higher levels of secretory leukocyte protease inhibitor (SLPI) and lower changes in CD68 and CTGF mRNAs were observed in patients who had less than 2 exacerbations post-BT. Lower levels of COL1A2 at baseline were observed in patients who had ACQ < 1.5 at 12 months post-BT. Conclusions: BT is effective irrespective of the asthma endotypes and seems associated with airway remodelling. Quantification of OCLN, CD68, CTGF, SLPI, COL1A2 mRNAs could be useful to identify patients with better results. Trial registration: The study protocol was approved by the Local Ethics Committee (Azienda USL-IRCCS of Reggio Emilia—Comitato Etico Area Vasta Nord of Emilia Romagna; protocol number: 2019/0014076) and all the patients provided written informed consent before participating in the study....
Background: The aim of this study was to investigate the characteristics and clinical outcomes of patients with nonsmoking small cell lung cancer (SCLC) using a nationwide registry in Korea. Methods: The Korean Association for Lung Cancer developed a registry in cooperation with the Korean Central Cancer Registry (KCCR) and surveyed approximately 10% of recorded lung cancer cases. Results: From 2014 to 2016, the KCCR registered 1,043 patients newly diagnosed with SCLC among a total of 8,110 lung cancer patients. In subgroup analysis, Kaplan meier survival analysis showed that the overall survival (OS) was significantly shorter in the nonsmoking subgroup than the ever-smoking subgroup of SCLC patients with extensive disease (6.99 vs. 9.68 months; P = 0.016). Among SCLC patients with limited disease, OS was also shorter in the nonsmoking subgroup, without statistical significance (19.4 vs. 23.5 months; P = 0.247). In a multivariate analysis using a Cox regression model, never smoking was not associated with shorter OS, but older age, extensive stage, poor performance status (Eastern Cooperative Oncology Group grade ≥ 2), male sex, no prophylactic cranial irradiation, and no active treatment (chemotherapy and/or radiotherapy) were associated with poor prognosis. Conclusion: This evaluation of an unbiased nationwide survey dataset revealed that a significant proportion of Korean SCLC patients were never-smokers. No history of smoking appeared to be a significant prognostic factor according to the univariate analysis but was confirmed to be statistically insignificant through a multivariate analysis of the total population. Reasons for a poor prognosis may include the possibility that a high rate of the elderly population is composed of nonsmokers who did not receive active treatment....
Background: Since nontuberculous mycobacterial pulmonary disease (NTM-PD) is common in middle-aged/elderly slender women at risk of osteoporosis, we hypothesized that NTM-PD could be associated with osteoporosis. The study aimed to evaluate the prevalence of osteoporosis in patients with NTM-PD compared with that in the general population and determine the factors associated with osteoporosis in the subjects, including the serum estradiol (E2) and 25-hydroxyvitamin D (25OHD) levels. Methods: We have recruited 228 consecutive adult patients with NTM-PD from a prospective cohort study at the Keio University Hospital, who had no history of osteoporosis or osteoporosis-associated bone fracture but underwent dual-energy X-ray absorptiometry-based bone mineral density (BMD) evaluation from August 2017–September 2019. The E2 and 25OHD levels were measured in 165 patients with available stored serum samples. We performed multivariable logistic regression analyses for osteopenia and osteoporosis. Results: Osteoporosis (T-score ≤ − 2.5) and osteopenia (T-score − 1 to − 2.5) were diagnosed in 35.1% and 36.8% of patients with NTM-PD, respectively. Compared with the general population, the proportion of osteoporosis was significantly higher in 50–59-, 60–69-, and 70–79-year-old women with NTM-PD. Multivariable analysis revealed that older age (adjusted odds ratio [aOR] for 1-year increase = 1.12; 95% confidence interval [CI] = 1.07–1.18), female sex (aOR = 36.3; 95% CI = 7.57–174), lower BMI (aOR for 1 kg/m2 decrease = 1.37; 95% CI = 1.14–1.65), and chronic Pseudomonas aeruginosa (PA) infection (aOR = 6.70; 95% CI = 1.07–41.8) were independently associated with osteoporosis. Additionally, multivariable analysis in 165 patients whose serum E2 and 25OHD levels were measured showed that both low E2 levels (< 10 pg/mL) and lower 25OHD levels were independently associated with osteoporosis. Conclusions: Middle-aged/elderly women with NTM-PD have a higher prevalence of osteoporosis than the general population. BMD screening should be considered in NTM-PD, especially in older females with severe diseases such as chronic PA infection and lower BMI, and low serum E2 and 25OHD levels....
Background: Acute respiratory infections (ARI) are recognized as an important cause of morbidity, mortality, and hospitalization among children in developing countries. Objectives: To identify the respiratory viruses circulating in Central African children before the SARS-COV2 pandemic and to assess the clinical manifestations. Methodology: This is a cross-sectional, descriptive, multicenter study, run from March 1, 2019, to March 31, 2020. Children aged 28 days to 15 year-old, with respiratory symptoms ≤10 days had been included. Nasopharyngeal swabs were taken and sent to the Institute Pasteur in Bangui (WHO National Referral Center for influenza). Virus research was done by cell and molecular culture techniques. Data were recorded and processed with Access 2019 software, then analyzed with STATA version 14 software. Chi-square test and ANOVA test were used to compare proportions at the p < 0.05 threshold. Results: Out of 659 children included during the study period, viruses were identified in 231 children, for an overall positivity rate of 35.05% (231/659). Rhinoviruses (RV) and influenza viruses were found in 66.23% and 16.88% respectively. Virus-virus co-infections were found in 10 (10/231) children (4.32%). Children under 5 years of age were more represented (78.60%). The main reasons for consultation were: fever (96.20%), cough (95.45%), runny nose (78.5%), and breathing difficulty (30.50%). ILI (Influenza-Like Illness) was found in 71.02% versus 28.98% of SARI (Severe Acute Respiratory Infection). There was a statistically significant association between age < 5 years and severity of acute respiratory infection (p = 0.001). The outcome was known for the 122 children at the CHUPB site with a mortality rate of 17.21% (n = 21). Conclusion: Viral ARI is common in children in Central African Republic. Care givers should think about it in order to reduce the inappropriate prescription of antibiotics....
