Former jean sandblasters die younger.

BACKGROUND: Silicosis remains a critical public and occupational health issue, exacerbated by its expansion into non-traditional industries and resulting in significant global morbidity and mortality. AIMS: This study aims to investigate the death rates associated with silicosis from jean sandblasting by comparing the results of diagnosed individuals to those of the general population. METHODS: Conducted from 2008 to 2023 in Tasliçay and Toklular villages, Bingöl City, Turkey, this retrospective cohort study analysed mortality among 220 diagnosed males versus 2851 undiagnosed residents. Data were derived from the Cohort database and validated with the Bingöl Provincial Health Directorate and the Turkish Statistical Institute. Statistical analysis involved univariate comparisons and survival analysis, utilizing the Mann-Whitney U-test, Kruskal-Wallis test and Cox proportional hazards model, with significance set at P < 0.05. RESULTS: The analysis revealed a silicosis mortality rate of 10% in diagnosed individuals over 15 years, notably higher than the 4% in the general population. Higher radiological profusions and younger ages at diagnosis were significant mortality factors. A radiological profusion above five notably increased the mortality risk by 1.37 times, with age and radiological density proving critical in survival rates. CONCLUSIONS: This research highlights the increased mortality risk in silicosis patients, particularly among former jean sandblasters, underscoring the significant effects of radiological density and early age exposure on mortality, thereby addressing a crucial gap in understanding the impact of silicosis on life expectancy and community health.

Performance of integrated pulmonary index for pulmonary embolism in dyspneic patients.

OBJECTIVES: The aim of this study was to evaluate the diagnostic capacity of integrated pulmonary index (IPI) in predicting the pulmonary embolism (PE) in patients admitted to emergency departments (ED) with dyspnea. BACKGROUND: The acute dyspnea is one of the most common chief complaints in EDs. PE is a potentially fatal disease and the delay in specific therapy increases the worst outcomes. METHODS: This study is a prospective methodological study, in which we evaluated the diagnostic performance of the IPI in predicting PE in patients admitted to ED with dyspnea. ROC analysis was used for estimating the accuracy of IPI and OCRS. RESULTS: Of the 144 patients included in the study, there were 20 (13.9 %) PE patients. In the ROC analysis, the best cut-off point for IPI was ≤ 2. For this cut-off point, the sensitivity and specificity of IPI were 100.0 % and 96.0 %, respectively. Besides, the accuracy of IPI was 96.5 % with a +LR of 24.8 and a -LR of 0.0. CONCLUSION: IPI was a potential candidate for evaluating the respiratory status, and a limiting tool to prevent unnecessary diagnostic tests and save time in determining the treatment course in dyspneic patients at ED (Tab. 5, Fig. 3, Ref. 34).

Female workers' silicosis diagnosis delayed due to gender bias.

After excluding alternative explanations, a silicosis diagnosis is based on the combination of appropriate silica exposure history and compatible clinical, radiological and occasionally pathological findings. Not taking appropriate occupational history by a physician may cause a misdiagnosis or underdiagnosis of silicosis. Herein, we present a female worker in a small-scale sandblasting factory who worked as a controller. Her silicosis diagnosis was established 10 years after her first symptoms, and she underwent invasive procedures due to a lack of inquiry about her occupational history. Gender bias may be one of the reasons that her occupational history was not taken.

Assessment of Palliative Care in Lung Cancer in Turkey.

OBJECTIVE: To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms. SUBJECTS AND METHODS: This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ2, Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis. RESULTS: The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled. CONCLUSION: In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey.

Investigation on the relationship between serum periostin, MMP-7, TGF-ß, and IL-18 levels and the clinical course and prognosis of COVID-19.

OBJECTIVE: Cytokines are involved in the inflammatory/anti-inflammatory balance and have been shown to play an important role in the course of COVID-19. This study aimed to evaluate the relationship of periostin, transforming growth factor-beta (TGF-ß), interleukin-18 (IL-18), and matrix metalloproteinase 7 (MMP-7) levels with clinical course and mortality in patients with early COVID-19 pneumonia. PATIENTS AND METHODS: A total of 150 hospitalized patients were diagnosed with COVID-19 between June and October 2021, and a control group of 30 healthy individuals were included in our study. The COVID-19 patients were divided into those who developed macrophage activation syndrome (MAS) in Group 1 and those who did not in Group 2. Serum periostin, MMP-7, TGF-ß, and IL-18 levels were measured from blood samples obtained at admission using enzyme-linked immunosorbent assay (ELISA). RESULTS: Periostin, MMP-7, and IL-18 levels were significantly higher in COVID-19 patients compared to the control group (p<0.001 for all). Periostin and MMP-7 levels were also significantly higher in Group 1 than in Group 2 (p<0.001 for both). Periostin, MMP-7, IL-18, and TGF-ß levels were significantly higher in non-surviving patients compared to survivors (p=0.04, p<0.001, p<0.001, and p<0.001, respectively). In the receiver operating characteristic (ROC) curve analysis, MMP-7 was found to have high sensitivity (90%) at a predictive value of 2.66 ng/mL. CONCLUSIONS: It is still not possible to predict which patients with early COVID-19 pneumonia will go on to develop MAS despite receiving standard treatment. The results of our study suggest that elevation of periostin and MMP-7 levels in the early period may predict the development of macrophage activation syndrome.

The relationship between COVID-19 and the complement system: mannose-binding lectin.

OBJECTIVE: Mannose-binding lectin (MBL) is one of the important parts of the complement system. In our study, we aimed to determine serum MBL levels and their relationship with intensive care hospitalization. PATIENTS AND METHODS: Ninety COVID-19-positive patients from outpatient clinics and clinics were included in this study. The patients were evaluated in three groups as mild, moderate, and severe groups. Each group consisted of 30 patients. A venous blood sample was taken once from each patient. Serum MBL, C-reactive protein (CRP), lactate dehydrogenase (LDH), fibrinogen, D-dimer, and ferritin levels were measured. RESULTS: The mean serum MBL levels of all patients were 695.46±324.42 ng/mL. One-way ANOVA test resulted in significant differences in serum CRP, LDH, fibrinogen, D-dimer, ferritin, and MBL levels between groups (p<0.05 for all comparisons). Post-hoc Tukey analysis showed significant differences in serum MBL levels between mild and severe groups and moderate and severe groups. CONCLUSIONS: MBL may be used as a prognostic biomarker in COVID-19 patients. Further studies are needed to determine MBL in treatment strategies.

Evaluation of the relationship between TAFI level and prognosis in COVID-19 patients.

OBJECTIVE: Serum thrombin-activated fibrinolysis inhibitor (TAFI) levels were measured in coronavirus disease 2019 (COVID-19) patients requiring intensive care, clinical hospitalization, and outpatient follow-up. The relationships between serum TAFI levels and prognosis were determined. PATIENTS AND METHODS: Ninety patients who had positive COVID-19 PCR test results were randomly selected and included in the study. Subgroups were formed according to the clinical characteristics of the patients as follows: mild, moderate, and severe. Venous blood samples were taken from all patients, and serum C-reactive protein (CRP), lactate dehydrogenase (LDH), fibrinogen, D-dimer, ferritin, and TAFI levels were measured. The results were evaluated by comparing each group. RESULTS: The one-way ANOVA test to determine differences between subgroups resulted in p-values lower than 0.05 for all biochemical analytes (CRP, LDH, fibrinogen, D-dimer, ferritin, and TAFI). Regarding serum TAFI levels, there were significant differences in the severe group (853.04 ± 338.58 ng/mL) compared to the mild group (548.33 ± 264.17 ng/mL). ROC curve analysis to predict mortality revealed that TAFI levels were able to detect 85% of deaths. In addition, ROC analysis revealed that serum TAFI levels could detect 86% of intubated cases. CONCLUSIONS: The disease progression is more severe in patients with high TAFI levels, and high TAFI levels are associated with mortality and intubation rates. Further studies are needed to determine serum TAFI levels as a biomarker of prognosis in COVID-19 patients.
