We conducted an epidemiological non-interventional cross-sectional and case-control study from 1 January 2023 until 26 May 2023 in Oltenia region, southwestern Romania. Throughout the research, 160 consecutive patients were included from two different clinical departments (1—Pneumology; 2—Diabetes and Nutritional Diseases). Subjects were voluntary adult individuals of any gender who expressed their written consent. The clinical data of the patients were correlated with the exposure to behavioral risk factors (diet, lifestyle, exposure to pollutants) to identify some negative implications that could be corrected to improve the quality of life of patients with simple chronic obstructive airway diseases of the lung or associated with metabolic syndrome (MS). In the first group of patients with respiratory diseases, there was a higher degree of exposure to toxic substances (43.75%) compared to the second group of patients with diabetes (18.75%); it is also noticeable that in the first group, there were noticeably fewer individuals who have never smoked (25%) compared to the second group (50%). Respiratory function impairment was observed to be more severe in overweight individuals. In the group of patients with known lung diseases, a positive correlation was noted between the presence of MS and respiratory dysfunctions of greater severity. Additionally, potential exacerbating factors affecting lung function, such as direct exposure to toxins and smoking, were considered. Potential secondary factors exacerbating respiratory dysfunction were considered by correlating biochemical parameters with dietary habits. These included reduced consumption of vegetables, inadequate hydration, and increased intake of sweets and products high in saturated or trans fats (commonly found in junk food), primarily due to their potential contribution to excess weight. Compared to patients without MS, the severity of the pulmonary function impairment correlated with the number of criteria met for MS and, independently, with an increase in weight.

Background. Obstructive ventilatory dysfunctions have an increased incidence, and through functional assessment determined by the International Classification of Functioning, Disability and Health (ICF), appropriate treatment can be established. Aims. The objectives of our research are represented by the application of respiratory rehabilitation sessions according to the ICF in patients with obstructive ventilatory dysfunctions-with COPD or asthma, using a unique, international language and the evaluation of the results obtained before and after completion pulmonary rehabilitation. Methods. We conducted a randomized prospective study between November 2022-April 2023, which included 84 patients diagnosed with obstructive ventilatory dysfunctions and who performed respiratory rehabilitation. They were divided into two categories: category 1-C1 which included 43 patients with Chronic Obstructive Pulmonary Disease-COPD and category 2-C2 which included 41 patients diagnosed with asthma. The rehabilitation program lasted 8 weeks, with exercises performed from Monday to Friday, with a weekend break. Respiratory rehabilitation consisted of physical therapy, inspiratory and expiratory muscle training (IEMT), proper nutrition, and psychotherapy. Results. At the end of the program, most of the patients showed improvements in the ICF qualifiers, a fact that supported us that respiratory recovery is one of the basic therapies of patients with obstructive ventilatory dysfunctions. Conclusions. The ICF allows the application of a personalized respiratory rehabilitation program. The ICF qualifiers are used for the functional assessment of patients and allow they to be included in individualized medical rehabilitation programs. [ABSTRACT FROM AUTHOR]

Background: The incidence of lung diseases is very high worldwide, especially in the case of lung cancer, pulmonary tuberculosis, and obstructive ventilatory dysfunctions. Alpha-1 antitrypsin (AAT) is synthesized mainly by hepatocytes, and one of its roles is to inhibit protease activity in the body's biological fluids following the phenomenon of programmed cell death, which is also called apoptosis. Acute lung diseases, but especially chronic ones, can cause, in addition to pulmonary and extrapulmonary manifestations, social and psychological impact, which is why a complex, interdisciplinary respiratory rehabilitation program is necessary. Objectives: Our study aimed to determine the correlation between alpha-1 antitrypsin values and lung diseases (pulmonary tuberculosis, lung cancer, asthma, and COPD) and to evaluate the influence of the individualized respiratory rehabilitation program in these diseases. Methods: We carried out a retrospective study between February 2022 and March 2023 in the Pneumology Department of the "Victor Babeș" Clinical Hospital of Infectious Diseases and Pneumoftiziology, Craiova. It included 189 patients diagnosed with pulmonary tuberculosis, lung cancer, or obstructive ventilatory dysfunctions (chronic obstructive pulmonary disease - COPD or asthma). Alpha-1 antitrypsin was collected from all patients. Respiratory rehabilitation was carried out both during hospitalization and in an out-patient setting for a maximum period of 6 months after discharge, with some patients even using telemedicine. Results: Increased values of alpha-1 antitrypsin were detected in advanced stages of the disease, and a clear improvement of clinical and functional parameters was observed after inclusion in the rehabilitation program. Conclusions: Detection of alpha-1 antitrypsin deficiency (AATD) is rare. The majority of patients diagnosed with lung cancer in advanced stages showed increased values of alpha-1 antitrypsin, AAT being able to be used as a follow-up marker in response to oncological treatment. Respiratory rehabilitation benefits in pulmonary tuberculosis, lung cancer, COPD, and asthma, regardless of the form of the disease. An interdisciplinary approach is necessary for the optimal treatment and control of lung diseases. [ABSTRACT FROM AUTHOR]

Background: Diet and lifestyle play important roles in preventing and improving chronic diseases, and evaluating behavioral risk factors in these pathologies allows for efficient management. Methods: A clinical study by screening biochemical parameters and pulmonary function was carried out to evaluate behavioral risk factors in obstructive pulmonary disease associated with metabolic syndrome. Results: Of the total of 70 patients included in the clinical study, 46 were men and 24 were women (χ2 = 3.9, p = 0.168). Forty-eight patients presented at least three met risk criteria associated with the metabolic syndrome (19 women and 29 men). Regarding the assessment of lung function, only 7 of the patients presented normal spirometry values (χ2 = 75.28, p < 0.001), and the other 63 patients presented with ventilatory dysfunction; most (over 80%) declared that they were smokers or had smoked in the past (χ2 = 5.185, p = 0.075). In terms of body weight, 45 of the patients are overweight or obese, most of them declaring that they do not consume enough vegetable products, they consume large amounts of foods of animal origin (meat, milk, eggs) but also super processed foods (food products type of junk food), do not hydrate properly, and are predominantly sedentary people (54 of the patients do no physical activity at all; χ2 = 2.12, p = 0.713). Conclusion: From the statistical processing of the data, it is noted that insufficient hydration, low consumption of vegetables, increased consumption of hyper-caloric food products rich in additives, sedentary lifestyle, and smoking are the main disruptive behavioral factors that worsen the health status in lung disease associated with the metabolic syndrome. An important conclusion emerging from the study is that the imbalances that aggravate obstructive lung diseases are generated by unhealthy food and an unbalanced lifestyle. [ABSTRACT FROM AUTHOR]

Autophagy, a homeostatic process involved in nutrient regeneration and immune responses, may be involved in intracellular killing of M. tuberculosis. Several studies linked variation in autophagy genes with susceptibility to pulmonary tuberculosis, but others did not confirm these findings.
