Knowledge, attitudes, and practices of cardiopulmonary rehabilitation among physiotherapists in Lebanon

Background Insufficient physical activity is one of the leading mortality risks worldwide for cardiovascular and pulmonary diseases. Physiotherapists (PT) are core healthcare professionals who play a major role in the prevention of disease complications and in inspiring a healthy lifestyle. To identify challenges in the promotion of cardiopulmonary rehabilitation (CR) in Lebanon, a survey was conducted among PT and physiotherapy students. The aim was to assess the knowledge, attitudes, and practices of CR in Lebanon. Results The response rate was 46.1% (N = 322). Results show that 24.5% of respondents have good to excellent knowledge about CR. More than 60% of the respondents indicate possible barriers to starting a CR program, and one of two respondents identify the absence of skills as a main barrier. Findings highlight the importance of the role of PT as a mediator to increase a healthy lifestyle among patients and to promote the prevention of cardiovascular diseases and pulmonary diseases in the country. Conclusions and recommendations Our results support the evidence and clinical guidelines that PT play a major role by increasing the participation of patients in CR. A cost-effective CR program needs to be covered by the private and public system in Lebanon.

Management of Medically Compromised Prosthodontic Patients

The medical evaluation of patients considering prosthodontic treatment is a vital step in the treatment planning. The prosthodontist should be able to assess the inherent risks associated with the treatment of patients with systemic conditions. Many factors are associated with evaluating the patient’s health status and risk including the patient’s current and past medical and dental history, current and past use of medications, type of treatment, length of treatment, invasiveness of treatment, and degree of urgency of treatment. In this article, some of the systemic diseases like arthritis, cardiovascular diseases, endocrine disorders, hematologic and oncologic disease, neurologic disorders, bone disorders, pulmonary diseases, liver diseases, and chronic kidney disease that commonly affect aged individuals are reviewed. The prosthodontic considerations that should be taken care of while managing patients with these systemic conditions will also be discussed.

Differentiating nontuberculous mycobacterium pulmonary disease from pulmonary tuberculosis through the analysis of the cavity features in CT images using radiomics

Objective To differentiate nontuberculous mycobacteria (NTM) pulmonary diseases from pulmonary tuberculosis (PTB) by analyzing the CT radiomics features of their cavity. Methods 73 patients of NTM pulmonary diseases and 69 patients of PTB with the cavity in Shandong Province Chest Hospital and Qilu Hospital of Shandong University were retrospectively analyzed. 20 patients of NTM pulmonary diseases and 20 patients of PTB with the cavity in Jinan Infectious Disease Hospitall were collected for external validation of the model. 379 cavities as the region of interesting (ROI) from chest CT images were performed by 2 experienced radiologists. 80% of cavities were allocated to the training set and 20% to the validation set using a random number generated by a computer. 1409 radiomics features extracted from the Huiying Radcloud platform were used to analyze the two kinds of diseases' CT cavity characteristics. Feature selection was performed using analysis of variance (ANOVA) and least absolute shrinkage and selection operator (LASSO) methods, and six supervised learning classifiers (KNN, SVM, XGBoost, RF, LR, and DT models) were used to analyze the features. Results 29 optimal features were selected by the variance threshold method, K best method, and Lasso algorithm.and the ROC curve values are obtained. In the training set, the AUC values of the six models were all greater than 0.97, 95% CI were 0.95–1.00, the sensitivity was greater than 0.92, and the specificity was greater than 0.92. In the validation set, the AUC values of the six models were all greater than 0.84, 95% CI were 0.76–1.00, the sensitivity was greater than 0.79, and the specificity was greater than 0.79. In the external validation set, The AUC values of the six models were all greater than 0.84, LR classifier has the highest precision, recall and F1-score, which were 0.92, 0.94, 0.93. Conclusion The radiomics features extracted from cavity on CT images can provide effective proof in distinguishing the NTM pulmonary disease from PTB, and the radiomics analysis shows a more accurate diagnosis than the radiologists. Among the six classifiers, LR classifier has the best performance in identifying two diseases.

Epigenetic Mechanisms in Parenchymal Lung Diseases: Bystanders or Therapeutic Targets?

Epigenetic responses due to environmental changes alter chromatin structure, which in turn modifies the phenotype, gene expression profile, and activity of each cell type that has a role in the pathophysiology of a disease. Pulmonary diseases are one of the major causes of death in the world, including lung cancer, idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PH), lung tuberculosis, pulmonary embolism, and asthma. Several lines of evidence indicate that epigenetic modifications may be one of the main factors to explain the increasing incidence and prevalence of lung diseases including IPF and COPD. Interestingly, isolated fibroblasts and smooth muscle cells from patients with pulmonary diseases such as IPF and PH that were cultured ex vivo maintained the disease phenotype. The cells often show a hyper-proliferative, apoptosis-resistant phenotype with increased expression of extracellular matrix (ECM) and activated focal adhesions suggesting the presence of an epigenetically imprinted phenotype. Moreover, many abnormalities observed in molecular processes in IPF patients are shown to be epigenetically regulated, such as innate immunity, cellular senescence, and apoptotic cell death. DNA methylation, histone modification, and microRNA regulation constitute the most common epigenetic modification mechanisms.

The Effect of Ocimum basilicum L. and Its Main Ingredients on Respiratory Disorders: An Experimental, Preclinical, and Clinical Review

Ocimum basilicum L. (O. basilicum) and its constituents show anti-inflammatory, immunomodulatory, and antioxidant effects. The plant has been mainly utilized in traditional medicine for the treatment of respiratory disorders. In the present article, effects of O. basilicum and its main constituents on respiratory disorders, assessed by experimental and clinical studies, were reviewed. Relevant studies were searched in PubMed, Science Direct, Medline, and Embase databases using relevant keywords including “Ocimum basilicum,” “basilicums,” “linalool,” “respiratory disease,” “asthma,” “obstructive pulmonary disease,” “bronchodilatory,” “bronchitis,” “lung cancer,” and “pulmonary fibrosis,” and other related keywords.The reviewed articles showed both relieving and preventing effects of the plant and its ingredients on obstructive pulmonary diseases such as chronic obstructive pulmonary disease (COPD), asthma, and other respiratory disorders such as bronchitis, aspergillosis tuberculosis, and lung cancer. The results of the reviewed articles suggest the therapeutic potential of O. basilicum and its constituent, linalool, on respiratory disorders.

Pneumocystis spp. in Pigs: A Longitudinal Quantitative Study and Co-Infection Assessment in Austrian Farms

While Pneumocystis has been recognized as both a ubiquitous commensal fungus in immunocompetent mammalian hosts and a major opportunistic pathogen in humans responsible for severe pneumonias in immunocompromised patients, in pigs its epidemiology and association with pulmonary diseases have been rarely reported. Nevertheless, the fungus can be quite abundant in porcine populations with up to 51% of prevalence reported so far. The current study was undertaken to longitudinally quantify Pneumocystis carinii f. sp. suis and other pulmonary pathogens in a cohort of 50 pigs from five Austrian farms (i.e., 10 pigs per farm) with a history of respiratory disease at five time points between the first week and the fourth month of life. The fungus was present as early as the suckling period (16% and 26% of the animals in the first and the third week, respectively), yet not in a high amount. Over time, both the organism load (highest 4.4 × 105 copies/mL) and prevalence (up to 88% of positive animals in the third month) increased in each farm. The relative prevalence of various coinfection patterns was significantly different over time. The current study unravelled a complex co-infection history involving Pneumocystis and other pulmonary pathogens in pigs, suggesting a relevant role of the fungus in the respiratory disease scenario of this host.

Chronic bronchopulmonary diseases in children with bronchial obstruction syndrome

Introduction. The results of long-term observations of children with chronic bronchopulmonary diseases occurring with bronchoobstructive syndrome and poorly responding to standard therapy are presented. To optimize treatment, it is necessary to accurately determine the nosological variant of the pathology, to identify the main causes of the formation of dysontogenetic disorders.Aim. To study the main nosological options and clinical and diagnostic criteria for chronic obstructive pulmonary diseases in children to justify an individual approach to treatment and follow-up.Materials and methods. 148 children with chronic bronchopulmonary diseases occurring with bronchial obstruction syndrome (excluding bronchial asthma and cystic fibrosis) were exаmined according to the differential diagnostic algorithm developed by us, including anamnestic, clinical, X-ray, functional and morphological methods.Results. The main group of 148 cases consisted of 73 children (49,3%) with lung malformations with insufficiency of the muscular-elastic and cartilaginous framework of the trachea and bronchi, local malformations, with impaired lung growth and development, causing bronchial obstruction. Acquired variants of chronic obstructive pulmonary diseases in children were noted by us in the form of chronic obstructive bronchitis (25.2%) and in the outcome of bronchopulmonary dysplasia (11.5%), chronic obliterating bronchiolitis (6.1%), gastroesophageal reflux disease (0.7%). Acquired local forms of obstruction (foreign object, scar stenosis, tumors) were noted in 4.5% of cases. Hereditary lung diseases, including primary ciliary dyskinesia, were detected in 2.7% of cases.Conclusion. Chronic obstructive pulmonary diseases are diseases of various etiology and pathogenesis that occur at an early age in children with perinatal disorders against the background of various lung malformations, bronchial dysplasia, lung tissue malformations and are the pathomorphological basis for the further formation of chronic obstructive pulmonary disease in adult patients.
