Introduction: Patients with end-stage renal disease (ESRD(Pos)) usually have multiple comorbidities and are predisposed to acute organ failure and in-hospital mortality. We assessed the effect of ESRD on the poorly understood long-term mortality risk after a first-ever mechanical ventilation (1-MV) for acute respiratory failure.Methods: The data source was Taiwan's National Health Insurance (NHI) Research Database. All patients given a 1-MV between 1999 and 2008 from one million randomly selected NHI beneficiaries were identified (n = 38,659). Patients with or without ESRD (ESRD(Neg)) after a 1-MV between 1999 and 2008 were retrospectively compared and followed from the index admission date to death or the end of 2011. ESRD(Pos) patients (n = 1185; mean age: 65.9 years; men: 51.5 %) were individually matched to ESRD(Neg) patients (ratio: 1:8) using a propensity score method. The primary outcome was death after a 1-MV. The effect of ESRD on the risk of death after MV was assessed. A Cox proportional hazard regression model was used to assess how ESRD affected the mortality risk after a 1-MV.Results: The baseline characteristics of the two cohorts were balanced, but the incidence of mortality was higher in ESRD(Pos) patients than in ESRD(Neg) patients (342.30 versus 179.67 per 1000 person-years; P <0.001; covariate-adjusted hazard ratio: 1.43; 95 % confidence interval: 1.31-1.51). For patients who survived until discharge, ESRD was not associated with long-term (>4 years) mortality.Conclusions: ESRD increased the mortality risk after a 1-MV, but long-term survival seemed similar.

Nutritional status could affect clinical outcomes in critical patients. We aimed to determine the prognostic accuracy of the modified Nutrition Risk in Critically Ill (mNUTRIC) score for hospital mortality and treatment outcomes in patients with severe community-acquired pneumonia (SCAP) compared to other clinical prediction rules. We enrolled SCAP patients in a multi-center setting retrospectively. The mNUTRIC score and clinical prediction rules for pneumonia, as well as clinical factors, were calculated and recorded. Clinical outcomes, including mortality status and treatment outcome, were assessed after the patient was discharged. We used the receiver operating characteristic (ROC) curve method and multivariate logistic regression analysis to determine the prognostic accuracy of the mNUTRIC score for predicting clinical outcomes compared to clinical prediction rules, while 815 SCAP patients were enrolled. ROC curve analysis showed that the mNUTRIC score was the most effective at predicting each clinical outcome and had the highest area under the ROC curve value. The cut-off value for predicting clinical outcomes was 5.5. By multivariate logistic regression analysis, the mNUTRIC score was also an independent predictor of both clinical outcomes in SCAP patients. We concluded that the mNUTRIC score is a better prognostic factor for predicting clinical outcomes in SCAP patients compared to other clinical prediction rules. [ABSTRACT FROM AUTHOR]

Background/Aims The results of dengue-infected adult patients requiring admission to the intensive care unit (ICU) remain unclear. We evaluated clinical outcomes and prognostic factors in patients with severe dengue fever. The predictors of liver complications and the associations with failure of other organs were reviewed; for example, age, gender, clinical manifestations, disease severity scores, underlying conditions, laboratory examinations, and outcomes. The primary endpoint was to find the predictors of ICU mortality. Methods In this retrospective study, all patients with laboratory-confirmed severe dengue infections were admitted to the ICU during the large outbreak period. Data is collected periodically and analyzed retrospectively. Results Overall, the minimum platelet count was 35,000 (SD, 43,000)/mm3 and was restored to 151,000 (SD, 107,000)/mm3 before the patient was discharged from the ICU. The highest levels of aspartate aminotransferase (AST/GOT) and alanine aminotransferase (ALT/GPT) were 1,126.4 IU/L (SD, 2,488.5 IU/L) and 395.7 IU/L (SD, 739.8 IU/L), respectively, with survivors. Compared to the activated part of the death group, thromboplastin time, lactic acid, AST/GOT and ALT/GPT levels were significantly elevated. However, the death of patients with albumin, hemoglobin and hematocrit was significantly reduced, and the trough and recovery platelet counts before they were discharged from the ICU were lower than survivors. Conclusions In conclusion, the mortality of severe dengue patients admitted to the ICU remains high, and the mortality was associated with lower GCS scores, lower platelet count before being discharged from the ICU discharge, and more organ failures. In addition, a significant portion of patients with severe dengue who die in the ICU have bacterial infections. These new treatment modalities should be considered for use on a case by-case basis, and more data is needed to support their usage. [ABSTRACT FROM AUTHOR]

Background: Truth-telling is an important step toward reducing the cognitive gap between physicians and patients as well as reducing the psychological pressures applied to physicians by family members. There is a lack of research on the truth-telling experience and needs in the intensive care unit from the perspective of patient family members., Purpose: This study is designed to explore the experiences and needs of families in the intensive care unit., Methods: A descriptive phenomenology method was used in this study. In-depth interviews were conducted with five participants who had family members assessed with acute physiology and chronic health evaluation II scores ≥ 20. Data were analyzed using Giorgi's phenomenological methods and Nvivo 11., Results: Four experience themes were examined, including (1) nothing is clear, requires explanation; (2) helpless to find answers, need a nurse to resolve this issue; (3) professional conduct makes us feel helpless, longing for love from the medical team; (4) decisions are very difficult, hoping to get more help., Conclusions / Implications for Practice: The family members expressed that they were unable to understand the underlying causes of the progression in patient condition because the medical team only presented outcomes to the family and did not discuss related causes. Thus, it is recommended that medical teams learn to recognize the cognitive processes of patient family members and consider their emotions, including their needs and expectations, in order to provide individualized explanations based on a patient's status and progress.

Objective: To investigate the concordance between novel and conventional surveillance paradigms for ventilator-associated pneumonia (VAP)., Methods: This study was conducted at a regional teaching hospital in southern Taiwan with 5 acute intensive care units. To assess the validity of novel ventilator-associated event (VAE) surveillance, we retrospectively applied the VAE algorithm to analyze all VAP cases that were identified using conventional definitions between April 2010 and February 2014. Patient outcomes, including ventilator days, hospital stay lengths, and in-hospital mortality were recorded., Results: Among 165 episodes of conventional VAP, 55 (33.3%), 40 (24.2%), 20 (12.1%), and 2 (1.2%) episodes were classified as a ventilator-associated condition, an infection-related ventilator-associated complication, possible VAP, and probable VAP, respectively, according to the new VAE algorithm. Changes in positive end-expiratory pressure and inspired oxygen fraction levels during the development of VAP were significant higher among each VAE category than for conventional VAP (all P < .001). In-hospital mortality was significantly higher among patients with ventilator-associated condition than for patients with conventional VAP (P = .0185)., Conclusions: In our study population, novel VAE surveillance only detected one-third of conventional VAP cases. Thus, more studies are needed to further validate VAE surveillance compared with conventional VAP by using strong microbiologic criteria, particularly bronchoalveolar lavage with a protected specimen brush for diagnosing VAP., (Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

Background: The mortality rate of patients with acute respiratory distress syndrome (ARDS) is still high despite the use of protective ventilatory strategies. We sought to examine the pharmacological effects of glutamine (GLN) in a two-hit model of endotoxin-induced inflammation followed by ventilator-induced lung injury (VILI). We hypothesized that the administration of GLN ameliorates the VILI., Methods: Sprague-Dawley rats were anesthetized and given lipopolysaccharide (LPS) intratracheally as a first hit to induce lung inflammation, followed 24 h later by a second hit of mechanical ventilation (MV) with either low tidal volume (6 mL/kg) with 5 cmH2O of positive end-expiratory pressure (PEEP) or high tidal volume (22 mL/kg) with zero PEEP for 4 h. GLN or lactated Ringer's solution as the placebo was administered intravenously 15 min prior to MV., Results: In the LPS-challenged rats ventilated with high tidal volume, the treatment with GLN improved lung injury indices, lung mechanics and cytokine responses compared with the placebo group., Conclusions: The administration of GLN given immediately prior to MV may be beneficial in the context of reducing VILI.

Background and Purpose: Leptospirosis is a major cause of fever in subtropical and tropical areas. The clinical manifestations are protean, ranging from very mild and nonspecific symptoms to severe septic shock and death. This retrospective study investigated the demographic and clinical features of leptospirosis in central Taiwan over 3 years, with emphasis on pulmonary manifestations., Methods: We analyzed the clinical characteristics of serologically-confirmed leptospirosis cases at a tertiary teaching hospital from October 2002 to October 2005., Results: Twenty three confirmed cases were included and Leptospira santarosai serovar Shermani was the most commonly identified serovar (77.3%). The male-to-female ratio was 2.67:1 and the average age was 42.4 years. Nineteen cases (82.6%) were hospitalized, 3 were diagnosed in the outpatient setting and 1 died before admission. The majority of cases (63.6%) occurred in rainy months (from June to October). Fever (incidence, 100%), anorexia (74%), headache (61%), gastrointestinal upset (53%), myalgia (48%), and cough (48%) were the common clinical manifestations. Fifteen cases (63%) had respiratory symptoms and twelve (52%) had chest roentgenography abnormalities. Multiple nodular densities pattern (42%) was the most common abnormal finding on chest plain film. Three patients met the criteria of Weil's syndrome. The overall mortality rate was 4.3%., Conclusions: Respiratory symptoms or abnormal findings on chest X-ray were not uncommon in patients with leptospirosis. In addition to hepatic or renal dysfunction, leptospirosis should be seriously considered in patients with pulmonary symptoms and fever, especially in subtropical and tropical areas.

Melioidosis is an endemic disease in southeast Asia and northern Australia, caused by Burkholderia pseudomallei. A typhoon-related outbreak occurred in southern Taiwan in July 2005. High mortality in melioidosis associated with bacteremic pneumonia and septic shock. We report a patient with life-threatening melioidosis who developed rapid progression of bacteremic pneumonia with acute respiratory distress syndrome, septic shock and multiple organ dysfunction and was successfully treated with recombinant human activated protein C (rhAPC) and meropenem. Although rhAPC has been reported to reduce the mortality of severe septic shock caused by various pathogens, to our best knowledge, this is the first reported case of rhAPC application in life-threatening melioidosis.

Background and Purpose: Group B streptococcus (GBS) [Streptococcus agalactiae] is an emerging cause of disease in non-pregnant adults with underlying diseases. This retrospective study analyzed 90 episodes of GBS bacteremia in adults occurring over a 4-year period., Methods: Basic and clinical data were collected by reviewing medical charts of patients. Blood cultures were performed on admission of patients suspected of bacteremia. Presence of underlying diseases, such as liver disease, heart disease, urinary tract disorders, and female-specific cancers, as well as possible portals of entry of infection was analyzed., Results: In 56 episodes (62.2%), patients were aged 60 years or older and 40 (44.4%) episodes occurred in males. Skin and soft tissue were the most common sources of GBS bacteremia (22/90, 24.4%). GBS bacteremia was classified as primary in 50% of the episodes (45 patients). Liver diseases were more common in males, while malignancy was more common in females. Portals of entry with a significant gender predominance included skin and soft tissue in women (p=0.018), bone and joint in women (p=0.016), and urinary tract in men (p=0.042). The overall mortality rate was 18.9% and the attributable mortality rate was 7.8%., Conclusions: Elderly people and those with underlying diseases are particularly susceptible to GBS infections. Preventive strategies, including GBS vaccine and skin care, are likely to be particularly important in these high-risk groups.

Necrotizing fasciitis is a life-threatening soft-tissue infection primarily involving the superficial fascia. This study investigated the microbiologic characteristics and determinants of mortality of this disease. The medical records of 87 consecutive patients with a diagnosis of necrotizing fasciitis from 1999 to 2004 were retrospectively reviewed. A single pathogen was identified as the infectious agent in 59 patients (67.8%), multiple pathogens were identified in 17 patients (19.6%), and no organism was identified in 11 patients (12.6%). Klebsiella pneumoniae, identified in 17 patients, was the most commonly isolated species. The most common comorbidity was diabetes mellitus (41 patients; 53.2%). Multivariate logistic regression analysis showed that more than 1 comorbidity, thrombocytopenia, anemia, more than 24 h delay from onset of symptoms to surgery and age greater than 60 were independently associated with mortality. This study found that K. pneumoniae was the most common cause of necrotizing fasciitis. Early operative debridement was independently associated with lower mortality.

Background: To determine why emergency department (ED) patients leave without being seen (LWBS) by a physician and to ascertain whether they receive alternative medical care., Methods: A cross-sectional study was conducted of patients who left without being seen by a physician between January 1 and June 30, 1999 in a medical center ED in northern Taiwan. Medical records were reviewed for population demographics, presenting complaints, and clinic acuity rating. Follow-up telephone interviews were conducted within 3 weeks after the patient left the ED., Results: Of 74,485 registered patients, 77 (0.1%) left without being seen by a doctor, and follow-up was achieved for 39.0% (30 of 77) of these. Ninety-seven percent (75 of 77) had low acuity ratings, and 58% (45 of 77) left within 60 min after registration. The respondents cited the following 3 leading reasons for leaving: prolonged waiting times (16 of 30, 53.3%), ED appeared busy (6 of 30, 20.0%), and self-referral to the hospital outpatient department (4 of 30, 13.3%). Most respondents believed that they should have been evaluated by a physician within 60 min of presentation. About half (14/30, 46.6%) of them sought further medical care within 24 h after they left the ED., Conclusion: In our study, only 0.1% of patients who sought care in the ED left without being seen by a physician. The majority of survey respondents had a low acuity rating and left because of long waiting times. Half of the patients who left without being seen sought alternative medical care.
