Body composition, pulmonary function tests, exercise capacity, and quality of life in chronic obstructive pulmonary disease patients with obesity.

Purpose Of The Study: Larger proportions of chronic obstructive pulmonary disease (COPD) patients are currently overweight or with obesity than underweight, and the combination of COPD and obesity is increasing. The purpose of this study was to investigate differences in the body composition, pulmonary function tests, exercise capacity, and health-related quality of life among normal weight, overweight, and obese patients with COPD.

Study Design: A total of 514 patients with COPD were included in the study.

Differences in nutritional status of patients with chronic obstructive pulmonary disease between Mediterranean and non-Mediterranean regions in Croatia.

The nutritional status of patients with chronic obstructive pulmonary disease (COPD) is a significant factor that influences the prognosis of the disease. This observational study aimed to analyze the nutritional status of COPD patients and assess the associations between nutritional status, disease severity, and exercise capacity in four different regions of Croatia. In this multicenter study, 534 COPD patients were recruited and evaluated concerning fat-free mass (FFM), FFM index (FFMI), skeletal muscle mass index (SMMI), phase angle (PhA), pulmonary function tests, and the 6-minute walk test (6MWT).

Delphi-Based Consensus on Interstitial Lung Disease Screening in Patients with Connective Tissue Diseases (Croatian National-Based Study).

The aim of this study was to develop a Croatian Delphi-based expert consensus for screening interstitial lung disease (ILD) associated with connective tissue disease (CTD). A systematic literature review was conducted on risk factors for the development of ILD, prevalence and incidence of ILD, diagnostic and screening methods for ILD, and prognosis of ILD in idiopathic inflammatory myopathy (IIM), mixed connective tissue disease (MCTD), primary Sjögren's syndrome (pSS), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSc) were performed. Based on the evidence found, experts developed questionnaires for screening and monitoring ILD in each CTD, which were provided via an online survey.

Risk factors for nontuberculous mycobacterial pulmonary disease (NTM-PD) in Croatia.

Background: The incidence, geographical distribution and clinical relevance of different nontuberculous mycobacteria (NTM) in Croatia are well described. There are few data on the risk factors for developing NTM pulmonary disease (NTM-PD) in this setting.

Methods: We conducted a retrospective cohort study on all Croatian residents with NTM isolated from respiratory samples in the period from 2006 to 2015 with follow-up to 2018.

Attitudes of Croatian pulmonologists concerning obstacles to earlier, more appropriate use of biologics in severe asthma: Survey results.

Aims: Biologics have been proven efficacious for patients with severe asthma (SA). It is essential to diagnose such individuals correctly. This study was designed to survey pulmonologists to identify barriers to early diagnosis and subsequent appropriate use of biologics for SA in Croatia.

Diagnostic value of tumour markers in pleural effusions.

Introduction: We investigated whether tumour markers carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cancer antigen 125 (CA-125), and cytokeratin 19 fragment (CYFRA 21-1) in pleural effusions and serum can be used to distinguish pleural effusion aetiology.

Materials And Methods: During the first thoracentesis, we measured pleural fluid and serum tumour marker concentrations and calculated the pleural fluid/serum ratio for patients diagnosed with pleural effusion, using electrochemiluminescence immunoassays. Receiver operating characteristic (ROC) analysis was carried out and the Hanley and McNeil method was used to test the significance of the difference between the areas under ROC curves (AUCs).

HLA class II sequence variants influence tuberculosis risk in populations of European ancestry.

Mycobacterium tuberculosis infections cause 9 million new tuberculosis cases and 1.5 million deaths annually. To identify variants conferring risk of tuberculosis, we tested 28.

Pericardial effusion as the first manifestation of occupational tuberculosis in a health care worker.

Tuberculosis (TB) is an infectious disease and, apart from protecting patients, attention must be given to protecting the persons who come in contact with them, especially nurses and medical practitioners. A 43-year-old immunocompetent male nurse developed occupationally disseminated TB after contact with patients affected by active TB (culture positive) while working in a psychiatric hospital. The first manifestation of the disease was exudative pericarditis with Mycobacterium tuberculosis (MT) confirmed two months after pericardiocentesis and evacuation of 1200 mL of pericardial effusion.

Association of variable number of tandem repeats in the coding region of the FAM46A gene, FAM46A rs11040 SNP and BAG6 rs3117582 SNP with susceptibility to tuberculosis.

We analyzed for association between the Family with sequence similarity 46, member A (FAM46A) gene (located on chromosome 6q14.1), BCL2-Associated Athanogene 6 (BAG6) gene (located on chromosome 6p21.3) and tuberculosis in Croatian Caucasian.

Tumor necrosis factor-alpha gene promoter -308 and -238 polymorphisms in patients with lung cancer as a second primary tumor.

Background: Lung cancer is the most common second primary cancer. We investigated whether the TNF-alpha-308 and TNF-alpha-238 polymorphisms were associated with the susceptibility and severity of lung cancer as the second primary cancer (LC2).

Material/methods: This study included 104 patients from the group LC2.

Osteopontin is associated with decreased apoptosis and αv integrin expression in lung adenocarcinoma.

Osteopontin (OPN) is a glycoprotein involved in invasion, progression and metastasis of many carcinomas. It contains several functional domains including binding sites for αv integrins, cell surface molecules playing a major role in mediating cell migration and adhesion. The aim of the study was to evaluate the expression of osteopontin in human non-small cell lung cancer (NSCLC) and to determine its possible prognostic significance as well as relation to apoptosis and αv integrin expression.

Heterozygous carriage of a dysfunctional Toll-like receptor 9 allele affects CpG oligonucleotide responses in B cells.

Toll-like receptors (TLR) are employed by the innate immune system to detect microbial pathogens based on conserved microbial pathogen molecules. For example, TLR9 is a receptor for CpG-containing microbial DNA, and its activation results in the production of cytokines and type I interferons from human B cells and plasmacytoid dendritic cells, respectively. Both are required for mounting an efficient antibacterial or antiviral immune response.

Primary spontaneous pneumothorax and mitral valve prolapse are not associated.

Background: Mitral valve prolapse (MVP) is a common diagnosis in patients with primary spontaneous pneumothorax (PSP). This description assumes that MVP and PSP might be manifestations of a systemic connective tissue abnormality. The purpose of this study was to determine the prevalence of MVP in PSP patients of Croatian origin and evaluate their relationship with connective tissue disorders.

Lower lobe pulmonary tuberculosis in immunocompetent male.

We present a case of 23-year-old student misdiagnosed for two months. Radiological finding showed a pneumonial infiltrate of left lung lower lobe. Antibiotical therapy was not resulting in a radiological regression.

[Malignant pleural mesothelioma in patients hospitalised at the Clinical Hospital Centre Rijeka between 1989 and 2008].

Malignant pleural mesothelioma (MPM) is a relatively rare tumour, mainly associated with occupational exposure to asbestos. We retrospectively analysed the records of MPM patients treated at the Pulmonology Department of the Clinic for Internal Diseases, Clinical Hospital Centre Rijeka between 1989 and 2008. to establish the incidence of MPM in that period.

Pneumocephalus after an uneventful scuba dive.

Scuba diving has become increasingly popular in the last 20 yr. Although it is considered safe, accidents, sometimes with fatal outcomes, do occur. The incidence of diving-related CNS barotrauma is low and it has been reported very infrequently.

Advancement in the mesothelioma diagnostics in Primorsko-Goranska County of Croatia.

The purpose is to find out whether the diagnostics and registration of patients with mesothelioma in the Littoral Mountainous County of Croatia corresponds to the world trends. Further, the intention was to show the incidence of the disease and suggest the measures of prevention in the county of 400,000 inhabitants and its center Rijeka with 140,000 people. To that purpose 43 patients with mesothelioma were monitored in two groups: 25 shipyard workers, mean age 66, and 18 workers in other occupations, mean age 62.
