Lung cancer (LC) has become one of the leading causes of preventable death in the last few decades. Cigarette smoking (CS) stays as the main etiologic factor of LC despite that many other causes such as occupational exposures, air pollution, asbestos, or radiation have also been implicated. Patients with chronic obstructive pulmonary disease (COPD), which also represents a major cause of morbidity and mortality in developed countries, exhibit a significantly greater risk of LC. The study of the underlying biological mechanisms that may predispose patients with chronic respiratory diseases to a higher incidence of LC has also gained much attention in the last few years...

BACKGROUND: C-reactive protein (CRP) measurement has proven valuable for detecting exacerbations, but its usefulness in predicting etiology remains controversial. Likewise, its potential value as a marker of severity, which is well established in patients with pneumonia, remains unproven in chronic obstructive pulmonary disease (COPD) exacerbations. METHODS: A cohort study of 118 patients with severe COPD and acute infectious exacerbations were included and followed up over 1 year...

BACKGROUND AND OBJECTIVES: Many conditions such as bacterial and viral infectious diseases, mechanical obstruction due to air and calculi and drugs can cause parotitis. We present a case of unusual bilateral parotitis in a patient under non-invasive continuous positive airway pressure (CPAP) therapy for chronic obstructive pulmonary disease exacerbation in intensive care unit. CASE REPORT: A 36-year-old patient was admitted to intensive care unit with the diagnosis of chronic obstructive pulmonary disease exacerbation...

Giant bullae often mimic pneumothorax on radiographic appearance. We present the case of a 55-year-old man admitted to a referring hospital with dyspnea, cough, and increasing sputum production; he refused thoracotomy for tension pneumothorax and presented to our hospital for a second opinion. A computed tomography (CT) scan at our hospital revealed a giant bulla, which was managed conservatively as an exacerbation of chronic obstructive pulmonary disease. Thoracic surgery was consulted but advised against bullectomy...

Gastrointestinal perforations are a complication of 2-10% of duodenal ulcers. There are a variety of etiologies associated with duodenal ulcer formation and its complications. Corticosteroid use is associated with an increased risk of duodenal ulcer perforation, with the first documented case in 1950. Other important medications associated with perforation include NSAIDS and opioids. Beyond medication, one of the most common disease processes, chronic obstructive pulmonary disease (COPD), has been found to be associated with peptic ulcer disease...

Chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation due to irritant-induced chronic inflammation. A postbronchodilator forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) ratio of 0.7 or less is diagnostic in a patient with dyspnea, chronic cough or sputum production, and a history of irritant exposure. Tobacco smoking is the most significant etiology, and smoking cessation is the only intervention shown to slow disease progression. Long-acting beta2-agonists and long-acting muscarinic antagonists are first-line treatments for patients with persistently symptomatic COPD with an FEV1 of 80% or less of predicted...

Lung cellular senescence and inflammatory response are the key events in the pathogenesis of chronic obstructive pulmonary disease (COPD) where cigarette smoke (CS) is the main etiological factor. Telomere dysfunction is induced by either critical shortening or disruption of the shelterin complex, leading to cellular senescence. However, it remains unknown whether disruption of shelterin complex is responsible for CS-induced lung cellular senescence. Here we show that TPP1 levels are reduced on telomeres in mouse lungs with emphysema, as well as in lungs from smokers and COPD patients...

BACKGROUND: COPD and congestive heart failure represent two disease entities of growing global burden that share common etiological features. Therefore, we aimed to identify the degree of left ventricular (LV) dysfunction in COPD as a function of COPD severity stages and concurrently placed particular emphasis on the presence of overlapping obstructive sleep apnea (OSA). METHODS: A total of 85 COPD outpatients (64.1±10.4 years, 54.1% males) and 20 controls, matched for age, sex, and smoking habits, underwent speckle tracking echocardiography for LV longitudinal strain imaging...

BACKGROUND: Hyponatremia is prevalent and associated with mortality in patients with heart failure (HF). The prevalence and prognostic implications of hyponatremia in acute exacerbation of chronic obstructive pulmonary (AECOPD) have not been established. METHOD: We included 313 unselected patients with acute dyspnea who were categorized by etiology of dyspnea according to established guidelines (derivation cohort). Serum Na+ was determined on hospital admission and corrected for hyperglycemia, and hyponatremia was defined as [Na+]<137 mmol/L...

BACKGROUND: COPD patients encounter episodes of increased inflammation, so-called acute exacerbations of COPD (AE-COPD). In 30% of AE-COPD no clear etiology is found. Since there is a well-known crosstalk between inflammation and thrombosis, the objectives of this study were to determine the prevalence, embolus localization and clinical relevance, and clinical markers of pulmonary embolism (PE) in unexplained AE-COPD. METHODS: A systematic search was performed using MEDLINE and EMBASE platforms from 1974 - October 2015...

Community-acquired pneumonia (CAP) is a serious infection that may occasionally rapidly evolve provoking organ dysfunctions. We aimed to characterize CAP presenting with organ dysfunctions at the emergency room, with regard to host factors and causative microorganisms, and its impact on 30-day mortality. 460 of 4070 (11.3%) CAP patients had ≥2 dysfunctions at diagnosis, with a 30-day mortality of 12.4% vs. 3.4% in those with one or no dysfunctions. Among them, the most frequent causative microorganisms were Streptococcus pneumoniae, gram-negatives and polymicrobial etiology...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. Smoking is the number one cause of COPD; however, genetic, environmental and dietary factors contribute to the etiology of this disease. In this study, we assessed the association between three diet quality indices -the Healthy Eating Index-2005 (HEI-2005), the Healthy Eating Index-2010 (HEI-2010), and Mediterranean Diet Score (MED)- and the severity of disease in COPD patients. METHODS: This cross-sectional study was performed at Rasul-e-Akram Hospital in Tehran on 121 COPD patients with the mean age of (SD) of 66...

Amyotrophic lateral sclerosis (ALS) is a rapidly fatal neurodegenerative disease of unknown etiology. We investigated the association between ALS diagnosis and prior cardiovascular disease (CVD), and CVD-specific, hospital admissions in the Danish population. We conducted a population based nested case-control study, including 3182 Danish residents diagnosed with ALS at age ≥20 years (1982-2009) and 100 randomly selected controls for each case, matched on age, gender and vital status. We estimated odds ratios (OR) associated with CVD, and CVD-specific hospital admissions, adjusting for socioeconomic and marital status, region of residence and past diabetes and obesity diagnoses...

OBJECTIVE: The aim of this study was to determine whether patients with heart failure (HF) who recover left ventricular ejection fraction (LVEF), termed here as 'Rec-HF', have a distinct clinical profile and prognosis compared with patients with HF and reduced LVEF (HF-REF) or HF and preserved LVEF (HF-PEF). METHODS: We evaluated and classified patients from the Spanish Heart Failure Registry into three categories based on enrollment/follow-up echocardiograms: HF-PEF (LVEF ≥50%), HF-REF (LVEF persistently <50%) and Rec-HF (LVEF on enrollment <50% but normalized during follow-up)...

Simultaneous infections with Cryptococcus neoformans and Histoplasma capsulatum are rare and typically occur in immunocompromised individuals, particularly AIDS patients. Because both of those fungi can spur the development of latent infections, it is generally unknown which organism was first present. The diagnosis of one fungus can hide the diagnosis of the other, leading to underdiagnoses and poor prognosis. We report a case of C. neoformans and H. capsulatum co-infection. We also performed a systematic review of the literature...

RATIONALE: Comorbidities, age, severity of illness, and high risk pathogens are well-known outcome determinants in community-acquired pneumonia (CAP). How these factors interact has not yet been clarified. OBJECTIVES: We conducted this study to analyze the complex interaction of comorbidities, age, illness severity, and pathogens in relation to CAP. METHODS: We performed a secondary analysis of the Community-Acquired Pneumonia Organization database to evaluate the impact of age in different age groups (<65, 65-79, and ≥80 yr), comorbidities (malignant disease, chronic obstructive pulmonary disease, renal and liver disease, cerebrovascular accident, congestive heart failure, and diabetes mellitus), severity of illness at admission, and etiology on the mortality of patients admitted to the hospital with CAP...

PURPOSE OF REVIEW: Loss of skeletal muscle mass and cachexia are important manifestations of chronic obstructive pulmonary disease and have been associated with breathlessness, functional limitation and poor prognosis. A number of other life-limiting illnesses, including cancer and chronic heart failure as well as acute conditions seen in ICU such as sepsis, are characteristically associated with cachexia and sarcopenia. These conditions may have respiratory muscle atrophy of sufficient magnitude to contribute to the development of breathlessness and associated functional limitation...

BACKGROUND: Low vitamin D status has been associated with short-term (30-day) mortality in hospitalized adults with community-acquired pneumonia (CAP). Data on its prevalence in these patients are scarce, and impact on long-term prognosis is unknown. We examined the prevalence of vitamin D deficiency and inadequacy and their effect on long-term mortality in hospitalized adults with CAP. METHODS: Secondary follow-up analysis of data from a prospectively recruited (January 2008-January 2011) well-defined cohort of 241 hospital survivors of CAP (Norway, latitude 60°N)...
