  • Purpose : Heart failure (HF) is considered an important medical burden with rehospitalization and mortality. Anemia is a major risk factor associated with the severity of HF. To improve the understanding of the impact of anemia in the population with HF, we explored the prevalence of anemia, its guidelines, relationship between anemia and mortality or rehospitalization, and limitation of reviewed papers of various populations with HF. Method: We used Whittemore and Knafl's integrative review methodology (2005), and thirty research papers were analyzed. PubMed, CINAHL, Cochrane, PsychInfo, Embase, Web of Science were searched for papers published between January 1960-June 2018. Results: Anemia in individuals with HF was primarily defined using the World Health Organization guideline. The prevalence of anemia in patients with HF varied from 9% to 56.7%. Moreover, such a condition significantly increases the prevalence of mortality or rehospitalization in patients with HF. The analyzed majority were non-prospective cohort study including secondary data analysis. Conclusion: Anemia in individuals with HF is a significant risk factor of mortality and rehospitalization. Prospective cohort studies should be designed to identify the optimal value for screening anemia and the impact of anemia on rehospitalization and mortality among HF patients.

  • Background : The development of bronchoscopic equipment along with the precision of radiographic techniques had reduced the mortality rate of patients with tracheobronchial foreign bodies but has been no change in the incidence of tracheobronchial foreign bodies since their introduction. The aim of this study was to assess the clinical characteristics of a tracheobronchial foreign body aspiration and to evaluate the efficacy of the treatment modality in children and adults. Methods : This is a retrospective review of 64 patients who underwent bronchoscopic procedures for the treatment of aspirated foreign bodies from December 1994 through March 2004 at the Chonnam national university hospital. Results : There were 47 males and 17 females, aged from 1 month to 78 years. Most of the patients had no underlying illness except for one patient with a cerebrovascular accident that contributed to the foreign body aspiration. The most common symptom was cough, which was noted in 54 patients (84.3%). The other presenting symptoms were dyspnea (48.8%), fever (20.3%), sputum (14%), vomiting (7.8%), and chest pain (4.6%). Those whose tracheobronchial foreign bodies were diagnosed more than 2 days after the aspiration (21 patients) were more likely to have pneumonia than those whose foreign bodies were diagnosed within 2 days (p = 0.009). Foreign bodies were visualized in the plain chest radiographs in 12 cases (18.8%), while others showed air trapping (21, 32.8%), pneumonia (15, 23.4%), atelectasis (7, 10.9%), and normal findings (9, 14.1%). The foreign bodies were more frequently found in the right bronchial tree (36) compared with the left bronchial tree (22, p = 0.04). In order to remove the foreign bodies, twenty (31.2%) cases were removed using flexible bronchoscopy, while 42 (65.6%) and 2 (3.2%) cases required rigid bronchoscopy and surgery, respectively. Conclusions : Tracheobronchial Foreign body aspiration had a bimodal age distribution in the infancy and old age around 60 years. They were found more frequently in the right bronchial tree. In addition, patients whose foreign bodies were diagnosed more than 2 days after the aspiration were more likely have a infection. Rigid bronchoscopy is the procedure of choice for uncooperative children and for those with foreign bodies lodged deeply in the small bronchial tree.
