ABSTRACT
Objectives To investigate the relationship between self-reported occupational noise exposure and levels of plasma inflammatory cytokines in asthmatic patients. Methods A total of 910 adult asthmatic patients were selected as the study subjects, and their occupational noise exposure history and other related information were collected. The peripheral blood samples were collected from the patients, and the expression levels of plasma soluble CD14 (sCD14), complement factor D (CFD), Eotaxin-11 (CCL11), and IL-9 were determined. The relationship between self-reported occupational noise exposure and the expression levels of the four inflammatory cytokines in patients’ plasma were analyzed using multiple linear regression models. The interactions between confounding factors and self-reported occupational noise exposure were further analyzed by interaction analysis. Results The plasma CCL11, sCD14 and CFD expressions in asthmatic patients with self-reported occupational noise exposure were significantly higher than those in patients without the exposure (P<0.05). After adjusting for confounding factors, compared with patients reporting no occupational noise exposure, the plasma CFD expression was increased by 0.17 (95% CI: 0.02, 0.31) natural logarithm units in patients with self-reported occupational noise exposure. During remission, the levels of plasma CCL11 and sCD14 in asthmatic patients with self-reported occupational noise exposure were increased by 0.27 (95% CI: 0.05, 0.49) and 0.22 (95% CI: 0.02, 0.41) natural logarithm units, respectively, when compared with patients without the exposure. Interaction analysis showed that self-reported occupational noise exposure had significant multiplicative interaction with smoking or pet ownership on plasma CCL11 or CFD expressions in asthmatic patients (all P<0.05). Conclusion Self-reported occupational noise exposure is significantly associated with increased expression levels of plasma CFD, CCL11, and sCD14 in adult asthmatic patients.
ABSTRACT
A large foreign body aspiration in a healthy adult is rare in the literature. It is a frequent problem in children and adolescents. Adults are affected in altered sensorium, either due to sedation or neurological problems. Acute upper airway obstruction though rare in adults requires establishment of an airway using Laryngoscope or rigid bronchoscope. At times we have to recourse to tracheostomy to save the life. Foreign body often travels down the right sided airways, here we present a case of 30mm Chicken bone being lodged in the left main bronchus. The patient presented with unremitting cough and normal chest skiagram. Monophonic wheeze on auscultation and focused attention on the patient narration made us clinch the diagnosis. New onset wheezy chest or unremitting chronic airway disease on adequate therapy, with history of choking needs special attention. The CT scan is a better modality of the investigation. Three dimensional CT with multi-slice virtual bronchoscopy is advantageous. We discussed foreign body aspirations in adults, the various causes and presentations. Fiber optic bronchoscopy is the ideal method for visualization and extraction of non-life-threatening foreign bodies in adults. Once a foreign body is identified, it has to be removed as early as possible. Retained foreign bodies can precipitate many complications related to infection and inflammation. At rare incidence we may have to resort to thoracotomy to remove a complicated foreign body.
ABSTRACT
Objective To analyze the clinical effect and the related performance of different tiotropium bromide in the treatment of adult asthma patients.Methods58 patients in the Second hospital of Shandong University from August 2014 to May 2016 admitted to the adult bronchial asthma, were randomly divided into observation group and control group, each of the 29 cases of patients, two patients were taken on the basis of routine treatment of tiotropium bromide in the treatment, the observation group in each given tiotropium 5 g treatment.The control group took a day sooner or later given tiotropium 2.5 g treatment, analysis of clinical effect of two groups were compared and the related performance.ResultsThis group of patients with different delivery methods after treatment, the observation group and the control group of arterial blood gas analysis results have significant difference compared to the clinical effect compared with statistical difference (P<0.05);treatment group the effective rate of treatment group and control the efficiency compared with significant differences (P<0.05);the two groups of patients after treatment, clinical symptoms were observed in groups of patients with asthma remission time were (6.24±1.92) d, while the control group was (8.33±2.47) d, the two groups were compared with statistical difference (P<0.05).ConclusionDifferent tiotropium dosing regimen for adult patients with asthma curative effect has significant clinical effect, compared with 5 per night given tiotropium Gtherapy and its clinical effect is more obvious.
ABSTRACT
Depression is an important comorbidity of asthma. However, little information is available about depression and its potential impact on asthma control in Korean adult asthma patients. We aimed to estimate the prevalence and risk factors for depression in Korean adults with persistent asthma. The 127 non-elderly (20-64 yr) and 75 elderly (> or =65 yr) patients with asthma were recruited. Demographic and clinical data were extracted, and the patients completed the Asthma Specific Quality of Life (AQOL) questionnaire and asthma control test (ACT). Depression status was defined using the Korean version of the Patient Health Questionnaire-9 (PHQ-9). Depression was more prevalent in non-elderly (18.9%) than in elderly patients with asthma (13.3%). Patients with depression were significantly younger, had lower economic status, shorter disease duration, poorer asthma control, and worse AQOL scores (P<0.05). Within the non-elderly group, younger age and shorter disease duration were significantly associated with depression (P<0.05). Within the elderly group, a higher body mass index and current smoking status were significantly associated with depression (P<0.05). The PHQ-9 score was significantly correlated with worse ACT and AQOL scores in both groups. In conclusion, depression is strongly associated with poor asthma control and quality of life in Korean adult asthma patients. Our results provide important clues that used to target modifiable factors which contribute to development of depression in asthma patients.
