The Presence of Smoking and Alcohol Imaginary in Popular Movies Available in Netflix Online Streaming Platform.

Exposure of tobacco and alcohol consumption in media and filmmaking has been related to promotion of smoking and drinking in adults. Current regulation aims to restrict tobacco and alcohol advertising in order to avoid alcohol consumption and smoking habits. We aimed to assess the impact of smoking and drinking habits in video-on-demand services.

"The Saint" gone good. Smoking and drinking over time in the popular series.

Background: Alcohol-related health and social problems are prevalent in almost all societies that consume alcohol and the presence of alcohol use in the movies is a known issue. The same holds true for smoking prevalence in film-making.

Objectives: The aim of this study is to assess tobacco-related content and alcohol consumption in "The Saint" series and movies.

Exercise Limitation in Children and Adolescents with Mild-to-Moderate Asthma.

Background: Children with uncontrolled asthma are less tolerant to exercise due to ventilatory limitation, exercise-induced bronchoconstriction (EIB), or physical deconditioning. The contribution of these factors in children with controlled mild-to-moderate asthma is unknown.

Objective: To explore the underlying mechanisms of reduced exercise capacity in children with controlled mild-to-moderate asthma.

Oesophageal atresia without major cardiovascular anomalies: Is management justified at a district paediatric surgical institution?

Background: Oesophageal atresia lacks sufficiently documented treatment approach, as guidelines are based rather on the opinion of experts than on systematic data. We aimed to answer the question if treatment of patients without major cardiovascular anomalies could be justified at a peripheral paediatric surgical institution, by evaluating the outcome of surgical correction.

Methods: Thirty-three neonates underwent surgery for correction of oesophageal atresia during a period of 20 years.

The Role of Interleukin-6 in the Pathogenesis, Prognosis and Treatment of Severe COVID-19.

A newly identified virus appeared in Wuhan, China, in December 2019, was named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and caused the coronavirus disease 2019 (COVID-19). SARS-CoV-2 presents similarities with two previous coronavirus pandemics, MERS (Middle East Respiratory Syndrome) and SARSCoV, concerning phylogenetic origin, structural composition, and clinical symptoms, thus, leading to common pathogenic mechanisms. The purpose of this review is to declare the role of interleukin-6 (IL-6) in the pathogenesis, prognosis, and treatment of COVID-19 by comparing its effect on SARS-CoV and MERS cases.

EBUS: Faster, cheaper and most effective in lung cancer staging.

The use of endobronchial ultrasound trans-bronchial needle aspiration (EBUS-TBNA) as the initial diagnostic and staging procedure in patients with suspected, non-metastatic lung cancer has gained substantial support, and is now recommended by numerous guidelines. Whereas considerable attention has been pointed to the reductions in costs achieved by EBUS-TBNA, that has not been the case for some of its more significant benefits, namely the reduction of the diagnostic work-up time and its ability to accurately assess and restage lymph nodes, which were previously stated incorrectly by CT or PET scan. Both these benefits translate into improved outcomes for patients, as delays are reduced, futile surgeries are prevented and curable operations can be performed on patients previously excluded by CT or PET scan.

Computed tomography cephalometric and upper airway measurements in patients with OSA and erectile dysfunction.

Purpose: Erectile dysfunction (ED) has been linked to obstructive sleep apnea (OSA). This study used computed tomography (CT) to identify cephalometric and upper airway anatomic features in patients with OSA that correlate with the presence of ED.

Methods: In this prospective study, 20 CT cephalometric and upper airway measurements, most commonly associated with OSA, were analyzed in 53 age- and BMI-matched consecutive eligible subjects.

Derived Arterial Stiffness is Increased in Patients with Obstructive Sleep Apnea and Periodic Limb Movements during Sleep.

Study Objectives: Both periodic limb movements during sleep (PLMS) and obstructive sleep apnea (OSA) have been associated with increased risk of cardiovascular disease (CVD). OSA has also been linked to increased large arterial stiffness, which is considered an independent risk factor for CVD. We utilized a previously validated index of large artery stiffness (SIDVP) derived from the digital volume pulse (DVP) to seek comparison in patients with PLMS and OSA.

Experience and limited lighting may affect sleepiness of tunnel workers.

Background: Working on shifts, especially on a night shift, influences the endogenous sleep regulation system leading to diminished sleep time and increased somnolence. We attempted to evaluate the impact of shifts on sleepiness and correlate the sleepiness score to the experience in a shift schedule.

Materials And Methods: This cross-sectional study consists of 42 male and 2 female workers involved in a tunnel construction.

Targeting leukotrienes for the treatment of COPD?

New drugs and new approaches of the treatment of chronic obstructive pulmonary disease (COPD) are needed. Despite recent advances in medical therapeutics, treatment of patients with COPD remains largely symptomatic. Although inhaled corticosteroids are currently the drug of choice for anti-inflammatory therapy, the inflammatory process in COPD is essentially steroid resistant.

Tuberculosis of the parotid gland.

Tuberculosis (Tbc) presented as an isolated parotid mass is rare. Preoperative diagnosis is difficult and the symptomatology is nonspecific. In the majority of the cases an initial diagnosis of a parotid tumor, often a pleomorphic adenoma, is made.

Lung function measurements in traditional bakers.

Background: Respiratory disease is common and amenable to early detection and management in the primary care setting. Spirometric and phlethysmographic evaluation of ventilatory function plays a critical role in the diagnosis, differentiation and management of respiratory illness such as asthma, chronic obstructive pulmonary disease and restrictive disorders.

Methods: Study subjects consisted of 58 workers in the production of bread and 45 salesclerks of bread from the same bakeries.

Pulmonary arterial hypertension: need to treat.

Pulmonary Arterial Hypertension (PAH) is defined by a persistent elevation in pulmonary artery pressure with normal left-sided pressures. It is characterized by increased pulmonary vascular resistance due to increased vascular tone and structural remodeling of pulmonary vessels. PAH is a quite rare condition, thus considering the rarity, subtle presentation, and diagnostic dilemma commonly posed by this disease, underdiagnosis and underreporting are probably widespread.

The alcoholic lung disease: historical background and clinical features.

The purpose of this review article is to prove the damage that alcohol causes to the respiratory system. We will make a brief review of alcohols history in the course of the centuries till nowadays. The problem of addiction to alcohol (alcoholism) will be examined for several countries.

Role and pharmacogenomics of TNF-alpha in asthma.

Asthma is a chronic heterogeneous inflammatory disease of the respiratory system in which numerous cytokines play a significant role. Among them TNF-alpha (tumour necrosis factor alpha), a proinflammatory cytokine, has a predominant role in orchestrating airway inflammation and affecting treatment outcome. In this review we attempt to summarize the involvement of TNF-alpha in the pathogenesis of asthma, illustrate variations of TNF-alpha gene that potentially influence asthma phenotype and highlight promising therapies by blocking the production of TNF-alpha or inhibiting its action.

Pulmonary alveolar microlithiasis in a patient with rheumatic valvular heart disease.

Pulmonary alveolar microlithiasis is a rare disease characterized by widespread intra-alveolar calcification of both lungs that is asymptomatic in the early stages. The disease typically follows a protracted course, and death can occur in 5 to 41 years after the initial diagnosis. Rheumatic fever is a multisystemic inflammatory disease that afflicts the child and juvenile population, and it is still very common in developing countries.

Genetic alterations of glutathione S-transferases in asthma: do they modulate lung growth and response to environmental stimuli?

Glutathione S-transferases (GSTs) constitute a super family of dimeric phase II metabolic enzymes that catalyze the conjugation of reduced glutathione with various electrophilic compounds and reactive oxygen species (ROS). Failure to detoxify ROS, as a sequel of altered GST genotype is able to aggravate the inflammatory cascade, promote bronchoconstrictor mechanisms, activate asthma-like symptomatology, and hamper lung development. Intriguingly, the same GST genotype can aggravate or improve physiological traits and maturation of respiratory system, from gestation to late adulthood.

Aseptic femoral head necrosis in a patient receiving long term courses of inhaled and intranasal corticosteroids.

Aseptic (avascular) necrosis of the femoral head in adults has been associated with a variety of disease entities. It is also recognized as a potential complication of systemic corticosteroid therapy. Inhaled corticosteroids are the first line anti-inflammatory agents for the long term treatment of asthma.

DNA sequence variations of metalloproteinases: their role in asthma and COPD.

Asthma and chronic obstructive pulmonary disease (COPD) are complex genetic diseases that cause considerable morbidity and mortality worldwide. Genetic variability interacting with environmental and ethnic factors is presumed to cause tobacco smoke susceptibility and to influence asthma severity. A disintegrin and metalloproteinase 33 (ADAM33) and matrix metalloproteinase-9 (MMP9) appear to have important roles in asthma and COPD pathogenesis.
