RESUMO
PURPOSE: This study aims to study the effects of depression and demoralization on suicidal ideation and to determine the feasibility of the Distress Thermometer as a screening tool for patients with cancer who experience depression and demoralization, and thus to establish a model screening process for suicide prevention. METHODS: Purposive sampling was used to invite inpatients and outpatients with lung cancer, leukemia, and lymphoma. Two hundred participants completed the questionnaire, which included the Distress Thermometer (DT), Patient Health Questionnaire-9 (PHQ-9), Demoralization Scale-Mandarin Version (DS-MV), and Beck Scale for Suicide Ideation. All data obtained were analyzed using SPSS 18.0 and SAS 9.3. RESULTS: Tobit regression analysis showed that demoralization influenced suicidal ideation more than depression did (t = 2.84, p < 0.01). When PHQ-9 ≥ 10 and DS-MV ≥42 were used as criteria for the DT, receiver operating characteristic analysis revealed that the AUC values were 0.77-0.79, with optimal cutoff points for both of DT ≥5; sensitivity 76.9 and 80.6 %, respectively; and specificity of 73.9 and 72.2 %, respectively. CONCLUSIONS: Demoralization had more influence on suicidal ideation than depression did. Therefore, attention should be paid to highly demoralized patients with cancer or high demoralization comorbid with depression for the purposes of suicide evaluation and prevention. The DT scale (with a cutoff of ≥5 points) has discriminative ability as a screening tool for demoralization or depression and can also be used in clinical settings for the preliminary screening of patients with cancer and high suicide risk.

PURPOSE: Acute respiratory failure requiring mechanical ventilation in severe community-acquired pneumonia has been shown to be a significant negative prognostic factor. We analyzed the early evolution of the Pao(2)/Fio(2) ratio and evaluated its clinical value as an outcome predictor. MATERIALS AND METHODS: This is a prospective study conducted in a tertiary referral hospital. In 62 adult patients requiring early mechanical ventilation due to severe community-acquired pneumonia, we measured serial changes in Pao(2)/Fio(2) ratio and other clinical variables within the first 48 hours of mechanical ventilation and compared the difference between survivors and nonsurvivors. RESULTS: The initial Pao(2)/Fio(2) ratio was lower in nonsurvivors (n = 27) than in survivors (n = 35) (158.0 +/- 55.8 vs 117.9 +/- 50.6, P = .025). Over the next 48 hours, the ratio increased significantly in survivors but not in nonsurvivors (analysis of variance, P < .001). An increase in Pao(2)/Fio(2) ratio greater than 56 mm Hg had a sensitivity of 75% and a specificity of 81% of survival. A definite causative pathogen was identified in 36 patients (58%) and the 3 most commonly isolated pathogens were Streptococcus pneumoniae, Staphylococcus aureus, and Klebsiella pneumoniae. Ten patients received inadequate initial empirical antimicrobial therapy, in which the Pao(2)/Fio(2) ratio change was significantly less than those who were adequately treated (analysis of variance, P < .001). Mortality was much higher (86% [6/7]) in patients who received inadequate antibiotics and where Pao(2)/Fio(2) ratio change was less than 56 mm Hg. On multivariate analysis, trend changes in Pao(2)/Fio(2) ratio over 48 hours, shock, and Acute Physiology and Chronic Health Evaluation II score were documented to be independent predictors of mortality. CONCLUSIONS: A progressive improvement of Pao(2)/Fio(2) ratio during the first 48 hours of mechanical ventilation indicates favorable outcome. Serial measurement of this ratio should be considered in decision making for therapeutic strategy.

Upper airway obstruction secondary to a carotid mycotic aneurysm has not been previously reported. We describe a patient with a mycotic aneurysm associated with a deep neck infection and presenting with acute tracheal obstruction. Recognition of this condition is important to avoid inadvertent rupture of the aneurysm in the course of diagnostic aspiration or surgical drainage. Physical findings, including a pulsating mass and an arterial bruit, in addition to appropriate imaging studies, may be helpful in suggesting the diagnosis. In particular, both neck and chest contrast-enhanced computed tomography scans may give important clues to the presence of a vascular lesion. In a patient with an infected neck mass and tracheal compression, a common carotid mycotic aneurysm should be considered in the differential diagnosis.

BACKGROUND/PURPOSE: Tuberculosis (TB) continues to pose a heavy public health burden in Taiwan. This prospective study analyzed the factors influencing treatment outcome in patients with TB treated with and without a hospital-based case management (HBCM) approach in a referral center in Taipei. METHODS: A register-based cohort study design was used to enroll all new cases of pulmonary or extrapulmonary TB from February 2003 to January 2004. The case manager served as the coordinator among patients, physicians and public health nurses, to facilitate compliance with anti-TB treatment. Treatment outcomes were assessed according to the consensus recommendations of the World Health Organization and the International Union Against Tuberculosis and Lung Disease. RESULTS: Suspected or confirmed pulmonary or extrapulmonary TB was diagnosed in 524 patients in our hospital from February 2003 to January 2004. Fifty-two of these patients were excluded due to duplicate reporting, previous treatment or death before enrollment. Out of 472 patients enrolled, 103 whose original diagnosis was revised were further excluded, leaving 369 cases eligible for analysis. Patients with case management had a significantly higher rate of successful treatment (cured plus completed treatment) compared to patients without case management, (240/277, 86.6% vs. 67/92, 72.8%; p = 0.002). The overall successful treatment rate including both case and non-case management was 83.2% (307/369), which was higher than the nationwide surveillance data of 78.3% in 2002 and 69.4% in 2003. CONCLUSION: Treatment of TB patients by a HBCM approach provides improved treatment outcomes compared to those without case management.

OBJECTIVE: The aim of the study was to describe the outcome of patients after 1 year's implementation of an integrated delivery system for respiratory care mandated by the National Health Insurance Bureau in Taiwan. DESIGN: A retrospective observational study was conducted in a step-down respiratory care center (RCC). PATIENTS: Patients included adults receiving prolonged mechanical ventilation (> or =21 days). MEASUREMENTS AND MAIN RESULTS: A total of 224 cases were available for review; 108 (48.2%) patients were successfully weaned. Those who failed weaning had a longer stay in the intensive care unit and RCC (25.1 vs 20.9 and 31.4 vs 18.6 days, P < .05), but there were no differences in the patients' ages (74.3 vs 70.4 years, P = .17) or the Simplified Acute Physiology Score II (52 vs 46.9, P = .18) before admission to the RCC. After discharge from the RCC, only 4.9% of the patients still on a ventilator were weaned within 1 year. Patients who failed weaning in the RCC had a shorter overall survival (5.2 vs 10.4 months, P < .05) and a lower 1-year survival (23.6% vs 44.6%, P < .05). CONCLUSION: Patients admitted to the RCC were still critically ill. Patients who failed weaning in the RCC had had a longer intensive care unit and RCC stay and a worse outcome after leaving the RCC.

This study was conducted to evaluate the effectiveness of personal protective equipment (PPE) against severe acute respiratory syndrome (SARS). Sixteen patients in a SARS cluster, including 4 health care workers (HCWs) and 12 non-HCWs were studied. We compared the initial viral load by nasopharyngeal swabs, clinical progression, and outcome of this cluster. The HCWs had a lower viral load. The non-HCWs had a higher mean C-reactive protein, lower oxygen saturation, and a higher incidence of intubation and death. Secondary household transmission developed in three of the non-HCWs' families. One month after discharge, non-HCWs had more signs of fibrosis on high resolution computed tomography (HRCT) scan and an impaired pulmonary function test. Although most of the PPE do not confer absolute protection against SARS, it seems that they may lower exposure to the virus, leading to a lower risk of secondary transmission, and be associated with relatively mild disease and a better early outcome.

To differentiate severe acute respiratory syndrome (SARS) from non-SARS illness, we retrospectively compared 53 patients with probable SARS and 31 patients with non-SARS who were admitted to Mackay Memorial Hospital from April 27 to June 16, 2003. Fever (> 38 degrees C) was the earliest symptom (50/53 SARS vs. 5/31 non-SARS, p < 0.0001), preceding cough by a mean of 4.5 days. The initial chest X-ray study was normal in 22/53 SARS cases versus 5/31 non-SARS cases. SARS patients with an initially normal chest X-ray study developed infiltrates at a mean of 5 +/- 3.44 days after onset of fever (21/22 SARS vs. 0/5 non-SARS). Rapid radiographic progression of unifocal involvement to multifocal infiltrates was seen in 22 of 24 SARS vs. 0 of 26 non-SARS patients (p < 0.0001). Pleural effusion was not present in any SARS patients but was seen in 6 of 26 non-SARS cases (p < 0.0001). Initial lymphopenia, thrombocytopenia, and elevated lactate dehydrogenase were all more common in SARS than non-SARS (p < 0.0001). They may help differentiate SARS from non-SARS if a reliable and rapid diagnostic test is not available.

STUDY OBJECTIVES: Severe acute respiratory syndrome (SARS) is a rapidly progressive disease caused by a novel coronavirus (CoV) infection. However, the disease presentation is nonspecific. The aim of this study was to define clearly the presentation, clinical progression, and laboratory data in a group of patients who had SARS. DESIGN: Retrospective observational study. SETTING: A tertiary care medical center with 51 negative-pressure isolation rooms in Taipei, Taiwan. PATIENTS: Fifty-three patients with SARS seen between April 27 and June 16, 2003. RESULTS: Fever (ie, temperature > 38 degrees C) was the most common symptom (98%) and the earliest. When admitted to the isolation unit of the hospital for observation, most patients reported nonspecific symptoms associated with their fever. Only two patients with preexisting illnesses had cough on the same day the fever began. Eventually, 39 patients (74%) developed cough, beginning at a mean (+/- SD) time of 4.5 +/- 1.9 days after fever onset, and 35 patients (66%) had diarrhea beginning at a mean time of 6.0 +/- 3.3 days after fever onset. Thirty-one patients (59%) had abnormal findings on chest radiographs on hospital admission, and all but 1 patient (98%) eventually developed lung infiltrates that were consistent with pneumonia. The majority of patients (63%) first developed unifocal infiltrates at a mean time of 4.5 +/- 2.1 days after fever onset, while in 37% of patients the initial infiltrates were multifocal, appearing at a mean time of 5.8 +/- 1.3 days after fever onset. Common laboratory findings included lymphopenia (on hospital admission, 70%; during hospitalization, 95%), thrombocytopenia (on hospital admission, 28%; during hospitalization, 40%), elevated lactate dehydrogenase (on hospital admission, 58%; during hospitalization, 88%), creatine kinase (on hospital admission, 18%; during hospitalization, 32%), and aspartate aminotransferase or alanine aminotransferase levels (on hospital admission, 27%; during hospitalization, 62%). Throat or nasopharyngeal swab for SARS-CoV by reverse transcriptase polymerase chain reaction (PCR) and real-time PCR was positive in 40 of the 47 patients (85%) in whom the test was performed. CONCLUSIONS: None of the presenting symptoms or laboratory findings are pathognomonic for SARS. Even though cough developed in a majority of patients, it did not occur until later in the disease course, suggesting that a cough preceding or concurrent with the onset of fever is less likely to indicate SARS. While PCR for SARS-CoV appears to be the best early diagnostic test currently available, it is clear that better methods are needed to differentiate between SARS and non-SARS illness on initial presentation.

From April 18 to May 31, 2003, 46 patients with probable severe acute respiratory syndrome were admitted to the negative-pressure isolation rooms of Mackay Memorial Hospital in Taipei, Taiwan. Their demographic, clinical, laboratory, and radiologic characteristics and clinical outcomes were analyzed. There were 15 males and 31 females, in this cohort, 13 of whom were healthcare workers. The latter included 6 hospital staff and 7 medical personnel transferred from other hospitals. The most common symptoms were fever (100%, 46/46), cough (72%, 33/46), shortness of breath (46%, 21/46), and diarrhea (39%, 18/46). Other common findings were lymphopenia (57%, 26/46), thrombocytopenia (39%, 18/46), elevated lactate dehydrogenase (63%, 29/46), and elevated creatine kinase (24%, 11/46). A total of 7 patients (15%) required mechanical ventilation, and 8 (17%) died. Advanced age was an independent significant risk factor for death. Fever followed by rapidly progressive respiratory compromise led to significant morbidity and mortality in this cohort.

BACKGROUND: The human leukocyte antigen (HLA) system is widely used as a strategy in the search for the etiology of infectious diseases and autoimmune disorders. During the Taiwan epidemic of severe acute respiratory syndrome (SARS), many health care workers were infected. In an effort to establish a screening program for high risk personal, the distribution of HLA class I and II alleles in case and control groups was examined for the presence of an association to a genetic susceptibly or resistance to SARS coronavirus infection. METHODS: HLA-class I and II allele typing by PCR-SSOP was performed on 37 cases of probable SARS, 28 fever patients excluded later as probable SARS, and 101 non-infected health care workers who were exposed or possibly exposed to SARS coronavirus. An additional control set of 190 normal healthy unrelated Taiwanese was also used in the analysis. RESULTS: Woolf and Haldane Odds ratio (OR) and corrected P-value (Pc) obtained from two tails Fisher exact test were used to show susceptibility of HLA class I or class II alleles with coronavirus infection. At first, when analyzing infected SARS patients and high risk health care workers groups, HLA-B*4601 (OR = 2.08, P = 0.04, Pc = n.s.) and HLA-B*5401 (OR = 5.44, P = 0.02, Pc = n.s.) appeared as the most probable elements that may be favoring SARS coronavirus infection. After selecting only a "severe cases" patient group from the infected "probable SARS" patient group and comparing them with the high risk health care workers group, the severity of SARS was shown to be significantly associated with HLA-B*4601 (P = 0.0008 or Pc = 0.0279). CONCLUSIONS: Densely populated regions with genetically related southern Asian populations appear to be more affected by the spreading of SARS infection. Up until recently, no probable SARS patients were reported among Taiwan indigenous peoples who are genetically distinct from the Taiwanese general population, have no HLA-B* 4601 and have high frequency of HLA-B* 1301. While increase of HLA-B* 4601 allele frequency was observed in the "Probable SARS infected" patient group, a further significant increase of the allele was seen in the "Severe cases" patient group. These results appeared to indicate association of HLA-B* 4601 with the severity of SARS infection in Asian populations. Independent studies are needed to test these results.
