Although foreign bodies in the tracheobronchial tree are rare in adults, the clinician must be aware of their likelihood. Foreign body aspiration should be considered especially in the etiology of recurrent lung diseases and in the presence of risk factors for aspiration, in particular with different neurologic and neuromuscular diseases. They can be successfully and safely removed in the majority of patients under local anesthesia by using FBSC. In cases when repeated procedure is needed, endotracheal tube is recommended.
BackgroundMycobacterium tuberculosis is a necessary, but not sufficient, cause of tuberculosis. A number of studies have addressed the issue of risk factors for tuberculosis development. Croatia is a European country with an incidence rate of 14/100 000 which is slowly decreasing. The aim of this study is to evaluate the potential demographic, socioeconomic, behavioural and biological risk factors for tuberculosis in Croatia in comparison to other high-income, low-incidence European countries.MethodsA total of 300 tuberculosis patients were matched for age, sex and county of residence to 300 controls randomly selected from general practitioners’ registers. They were interviewed and their medical records were evaluated for variables broadly described as potential risk factors.ResultsIn multiple logistic regression, the following factors were significant: parents born in a particular neighbouring county (Bosnia and Herzegovina) (OR = 3.90, 95% CI 2.01-7.58), the lowest level of education (OR = 3.44, 95% CI 1.39-8.50), poor household equipment (OR = 4.72, 95% CI 1.51-14.76), unemployment (OR = 2.69, 95% CI 1.18-6.16), contact with tuberculosis (OR = 2.19, 95% CI 1.27-3.77), former (OR = 2.27, 95% CI 1.19-4.33) and current smoking habits (OR = 2.35, 95% CI 1.27-4.36), diabetes (OR = 2.38, 95% CI 1.05-5.38), a malignant disease (OR = 5.79, 95% CI 1.49-22.42), being underweight in the previous year (OR = 13.57, 95% CI 1.21-152.38).ConclusionIn our study, the identified risk groups for tuberculosis reflect a complex interaction between socioeconomic conditions, lifestyle and non-communicable diseases. Interventions focused on poverty will undoubtedly be useful, but not sufficient. Tuberculosis control would benefit from a combination of broad public health activities aimed at the prevention and control of risky lifestyles and non-communicable diseases, interventions outside the health sector, and efforts to constantly improve the Croatian national tuberculosis programme.
BackgroundDelayed diagnosis and treatment of tuberculosis increase both the severity of the disease and the duration of infectivity. A number of studies have addressed the issue of health system delays in the treatment of tuberculosis, but mostly in countries with a high or low incidence of the disease. Our understanding of delay is quite limited in settings with an intermediate burden of tuberculosis. We explore the duration and factors associated with delays in the Croatian health system which has free health care and a sufficient network of health services providing tuberculosis diagnosis and care.MethodsA total of 241 consecutive adults with culture-confirmed pulmonary tuberculosis were interviewed in seven randomly selected Croatian counties and their medical records were evaluated. A health system delay was defined as the number of days from the first consultation with a physician to the initiation of anti-tuberculosis treatment. A long delay was defined as a period exceeding the median delay, while an extreme delay was considered to be above the 75th percentile delay.ResultsThe median health system delay was 15 days while the 75th percentile was 42 days (the 5th and 95th percentile being 1 and 105 days respectively). Almost 30% of tuberculosis patients remained undiagnosed for more than 30 days after the initial health care visit. Female patients (p = 0.005), patients with a negative sputum smear (p = 0.002) and patients having symptoms other than the usual ones (0.027) were found to be in significant correlation with a long delay. In a multivariate model, a long delay remained associated with the same variables (p = 0.008, p = 0.003, and p = 0.037, respectively).A significant association was demonstrated between both the female gender (p = 0.042) and a negative sputum smear (p < 0.001) and extreme delay, while only a negative sputum smear (p < 0.001) remained significant in the multivariate analysis.ConclusionsOur findings suggest that some groups of tuberculosis patients experienced a health system delay. In such a setting where tuberculosis incidence is decreasing, which leads to a lack of physician experience and expertise, training in tuberculosis is required. Such measure may be useful in reducing the number of missed opportunities for tuberculosis diagnosis.
It was established that the COVID-19 pandemic resulted in decreased physical activity levels, potentially leading to reduced physical fitness. The aim of this research was to investigate the impact of the COVID-19 lockdown on fitness indices in adolescents. We observed high school adolescents (33% girls; aged 15–17 years) divided into two cohorts. The first cohort (control; n = 48) included adolescents who were in school during the 2018/2019 year, while the second cohort (lockdown; n = 66) was observed during the school year 2019/2020 when COVID-19 lockdown measures were imposed. Variables included body height, body mass, BMI, sit-ups, and the 600 m dash. Both cohorts were tested at the beginning and at the end of the observed school years. A factorial analysis of variance for repeated measurements evidenced an improvement in sit-ups and the 600 m dash in the control, and a decrease of the same capacities in the lockdown cohort. In the lockdown cohort, a decrease in muscular fitness was more evident in boys than in girls. No differential changes between cohorts were evidenced in anthropometrics. Results suggest that the COVID-19 lockdown negatively influenced muscular fitness status in adolescents, especially in boys.
Objectives: The physical activity level (PAL) has significantly decreased as a result of the social distancing and lockdown related to the COVID-19 pandemic, but there is a lack of knowledge on the correlates of PAL during the pandemic. The aim of this research was to examine the influence of pre-pandemic sports participation and substance use and misuse (SUM) on PAL during the COVID-19 pandemic. Material and Methods: The study included 661 high-school students from Bosnia and Herzegovina (aged 15-18 years, 292 females). The investigation included 2 testing waves: before the COVID-19 pandemic (baseline, January 2020) and during the COVID-19 lockdown (follow-up, April 2020). The variables included PAL as measured by the Physical Activity Questionnaire for Adolescents, sports factors, and SUM. Results: Sports factors at baseline were positively correlated with PALs at both baseline and follow-up. Smoking tobacco negatively affected PALs at both baseline and follow-up. Alcohol consumption was positively correlated with PAL at baseline but had no effect on PAL at follow-up. Conclusions: This study confirmed the importance of sports participation in maintaining PAL during challenging situations, such as the COVID-19 lockdown. The substance-specific influence of SUM on PAL before and during the lockdown points to evident social and cultural aspects of SUM behaviors in adolescents. Further studies evidencing the cumulative effects of PAL decline during the lockdown are warranted.
This study found evidence of cell and tissue injury in the lung, a lowering of pH and higher bronchoalveolar aspirate LDH levels in patients with GERD compared with healthy subjects. These findings suggest that pulmonary function, and especially DL(CO), should be evaluated in patients presenting with GERD.
The impact of the COVID-19 pandemic in sport has been the subject of numerous studies over the past two years. However, knowledge about the direct impact of COVID-19 infection on the performance of athletes is limited, and the importance of studies on this topic is crucial during the current pandemic era. This study aimed to evaluate the changes in the match running performance (MRP) of professional soccer players that occurred as a result of COVID-19 infection after fulfilling all of the prerequisites for a safe return to play (RTP). The participants were 47 professional soccer players from a team which competed in first Croatian division (21.6 years old on average) during the 2020/21 season. The total sample was divided into two subgroups based on the results of a PCR test for COVID-19, where 31 players tested positive (infected) and 16 tested negative. We observed the PCR test results (positive vs. negative PCR), the number of days needed to return to the team, number of days needed to RTP after quarantine and isolation, and MRP (10 variables measured by a global positioning system). The number of days where the infected players were not included in the team ranged from 7 to 51 (Median: 12). Significant pre- to post-COVID differences in MRP for infected players were only found for high-intensity accelerations and high-intensity decelerations (t-test = 2.11 and 2.13, respectively; p < 0.05, moderate effect size differences), with poorer performance in the post-COVID period. Since a decrease of the MRP as a result of COVID-19 infection was only noted in two variables, we can highlight appropriateness of the applied RTP. However, further adaptations and improvements of the RTP are needed with regard to high-intensity activities.
BackgroundSeveral studies have suggested that idiopathic pulmonary fibrosis (IPF) may be related to repeated aspiration of gastric contents over long periods of time. We aimed to investigate differences between pH measured directly in the lung, and biomarkers of acute inflammation in patients with newly diagnosed IPF and in patients with newly diagnosed GERD.Material/MethodsAll subjects (N=61) underwent collection of medical history, physical examination, pulmonary function testing, bronchoscopy, endoscopy, arterial blood gas analyses, and biochemical testing.ResultsPreviously diagnosed GERD was found in 56.7%, typical symptoms of reflux in 80%, and Helicobacter pylori in gastric biopsy specimens in 76.6% of the cases. pH in peripheral branches of bronchi in the cases was 5.32±0.44 and was 6.27±0.31 (p<0.001) in the control group. The average values of LDH, ALP, and CRP in bronchoalveolar aspirate and in serum, as well as TNF-α in bronchoalveolar aspirate, were significantly higher in IPF patients.ConclusionsThe more acidic environment in the bronchoalveolar aspirate of the IPF subjects could contribute to the development or progression of IPF, possibly via changes in local metabolism or by damaging local cells and tissue. However, further studies with larger numbers of patients are required to clarify the role of gastric fluid aspiration in IPF pathogenesis. Our preliminary work has identified inflammatory biomarkers LDH, ALP, and TNF-α as potentially important in the pathologic processes in IPF. Further research is needed to determine their importance in clinical intervention and patient care.
