RESUMEN
Transfusion reactions induced by platelet transfusions may be reduced and alleviated by leukocyte reduction of platelets. Although leukoreduction of apheresis platelets can be performed either pre-storage or post-storage, seldom studies directly compare the incidence of transfusion reaction in these two different blood products. We conducted a retrospective study to compare the transfusion reactions between pre-storage and post-storage leukoreduced apheresis platelets. We reviewed the general characteristics and the transfusion reactions, symptoms, and categories for inpatients who received pre-storage or post-storage leukoreduced apheresis platelets. Propensity-score matching was performed to adjust for baseline differences between groups. A total of 40,837 leukoreduction apheresis platelet orders were reviewed. 116 (0.53%) transfusion reactions were reported in 21,884 transfusions with pre-storage leukoreduction, and 174 (0.91%) reactions were reported in 18,953 transfusions with post-storage leukoreduction. Before propensity-score matching, the odds ratio for transfusion reactions in the pre-storage group relative to the post-storage group was 0.57 (95% confidence interval [CI] 0.45-0.72, P < 0.01); the odds ratio after matching was 0.63 (95% CI 0.49-0.80, P < 0.01). A two-proportion z-test revealed pre-storage leukoreduction significantly decreases the symptoms of chills, fever, itching, urticaria, dyspnea, and hypertension as compared with those in post-storage leukoreduction. Pre-storage leukoreduced apheresis platelet significantly decreased febrile non-hemolytic transfusion reaction as compared with post-storage groups. This study suggests pre-storage leukoreduction apheresis platelet significantly decreases the transfusion reaction as compared with those in post-storage leukoreduction.

This study aimed to compare the diagnostic values of SARC-F (strength, assistance with walking, rising from a chair, climbing stairs, and falls), SARC-Calf (SARC-F combined with calf circumference), CC (calf circumference), and the Yubi-wakka (finger-ring) test for screening for sarcopenia in community-dwelling older adults. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used as a standard reference. A total of 209 participants were enrolled, and 40.7% were identified as sarcopenia. The sensitivity, specificity, and AUC were respectively 54.1%, 70.2%, and 0.687 for SARC-F; 76.5%, 73.4% and 0.832 for SARC-calf, 86.7%, 82.4%, and 0.906 for CC in men, and 85.5%, 63.3%, and 0.877 for CC in women. Relative to the "bigger," a significant association between sarcopenia and the Yubi-wakka test ("just fits" OR: 4.1, 95% CI: 1.57-10.98; "small" OR: 27.5, 95% CI: 10.14-74.55) was observed. The overall accuracy of CC was better than SARC-Calf for sarcopenia screening.

Bacteraemia is a systemic infection associated with strong febrile immune reactions. Fever definitions, fever intensity and other factors might affect the recognition, management and prognosis of patients with bacteraemia. A prospective observational design was used to study 412 consecutive Taiwanese patients with healthcare-associated bacteraemia. The study variables were fever intensity, factors related to fever intensity, the association of physical function to thermogenic capacity and the sensitivity of three definitions of fever for identifying patients with bacteraemia. Age, Charlson comorbidity index (CCI) score, chills and pathogen types were predictors of fever intensity. Barthel index score, CCI score and pathogen types were predictors of chills, an indicator of thermogenic capacity. The sensitivity of three fever definitions (basal body temperature plus 1°C, ≥ 38°C and ≥ 38.3°C) to identify patients with bacteraemia was 93.3%, 83.5% and 71.4%, respectively. Clinicians can target patients with factors associated with blunted febrile response to bacteraemia for closer monitoring.

OBJECTIVE: Sleep disturbances among family caregivers (FCs) are common in advanced cancer. The comprehensive factors for sleep disturbances among the FCs of patients with cancer have not been investigated in Taiwan. The purposes of this study were to investigate the sleep disturbances among the FCs of patients with advanced cancer and to determine predictors of sleep disturbance. METHODS: A descriptive, cross-sectional study was conducted among 172 FCs. Data were collected using the Pittsburgh Sleep Quality Index and wrist actigraphy. A linear regression model was used to identify the predictive factors for sleep quality. RESULTS: Seventy-six percent of the FCs experienced some sleep disturbances. Female gender, more fatigue, greater depression, more caregiving burden, and spending over 16 h per day on caregiving tasks were risk factors for sleep disturbances in caregivers. CONCLUSIONS: Sleep disturbances were common among the Taiwanese FCs of patients with advanced cancer. FCs with risk factors for sleep disturbances should be identified and provided assistance.

BACKGROUND: Cancer caregivers experience significant stress due to their multifaceted role. Current support methods are limited by unidimensional assessments. OBJECTIVE: The aim of this study was to evaluate a Web-based support system aimed at reducing caregiver stress and anxiety, and improving resilience, vigilance, and quality of life, using both subjective and objective measures. METHODS: A randomized controlled trial with a single-center, 2-arm parallel design and longitudinal assessment was conducted in Taiwan. Caregivers of patients recently diagnosed with cancer were randomly allocated to either a standard care group or an intervention group that received enhanced nurse-led support. Metrics including psychological resilience, caregiver burden, anxiety, quality of life, stress levels, and vigilance were systematically evaluated on a monthly basis over a period of 5 months, starting from the initial baseline measurement. RESULTS: Following the intervention, participants in the intervention group exhibited statistically significant reductions in caregiver burden and anxiety, alongside a notable improvement in resilience. Objective evaluations revealed a significant reduction in stress levels within this group. However, there were no discernible differences in vigilance and quality of life metrics between the intervention and control groups. CONCLUSION: The Web-based program effectively reduced caregiver stress and burden, as indicated by multiple metrics. IMPLICATIONS FOR PRACTICE: This accessible and efficient Web-based support is beneficial for cancer caregivers facing diverse challenges.
RESUMEN
BACKGROUND: Insufficient exercise affects the health of patients who have implantable cardioverter defibrillators (ICD). The purpose of this study was to investigate the correlations between exercise self-efficacy (ESE) and its associated psychological factors in ICD recipients. METHODS: This cross-sectional study included individuals who had undergone ICD implantation at the cardiology department of a medical centre in Taiwan. A face-to-face survey was conducted. The survey questionnaire included questions regarding the participants' demographics, perceived health (PH), ICD shock-related anxiety (ICD-SRA), self-care self-efficacy (SSE), perceived exercise benefit (PE-benefit), perceived exercise barrier (PE-barrier), and ESE. Data were analysed using SPSS 20.0 Software. Stepwise multiple regression analyses were also performed to evaluate the predictive effects of the aforementioned factors on ESE. RESULTS: A total of 52 ICD recipients were enrolled. ESE was negatively correlated with ICD-SRA (r = -0.511; p < 0.01) and PE-barrier (r = -0.563; p < 0.01), but positively correlated with SSE (r = 0.339; p < 0.05) and PE-benefit (r = 0.464; p < 0.01). The stepwise multiple regression analysis revealed that PE-barrier, PE-benefit, and ICD-SRA effectively predicted ESE in the participants. CONCLUSIONS: ESE may be improved by overcoming PE-barrier, ICD-SRA and enhancing PE-benefit. Consequently, improving ESE may enhance the health benefits of exercise.

OBJECTIVE: This study aimed to determine the effect of age on febrile response in patients with healthcare-associated bloodstream infection (BSI). METHODS: This was a retrospective observational study using medical records as the primary source of data. Three indicators measured body temperature changes: basal body temperature (BBT), body temperature at infection onset (onset T), and maximum temperature (max T) during the infection period. RESULTS: In a sample of 230 patients there was no significant correlation between BBT or onset T and age. Max T was significantly correlated with age (r = -.191, p = .004). There was wide variation in onset T in all age groups. CONCLUSIONS: Age showed no effect on BBT and onset T, but blunted max T in patients with bacteremia. This variability in onset T in all age groups emphasizes the need for early recognition of subtle signs of infection and the need to use an individualized definition of fever.

Non-O1/non-O139 Vibrio cholerae (NOVC) causes various illnesses ranging in severity from mild to life-threatening but were ignored previously. Knowledge of the NOVC infection, particularly bacteremia, is limited because of its rarity. Here we first retrospectively reported the demographic, clinical, and therapy characteristics of patients with NOVC infection. Isolated NOVC stains were identified by a series of biochemical, mass spectrometry (MS), and serum agglutination tests. The results of 11 patients with NOVC infection (including 8 with bacteremia) with a median age of 68 years were included in this report. Most isolated NOVC strains had antibiotic susceptibility. Patients with NOVC-positive were distributed in various departments, most occurring in gastroenterology (6 cases). Hepatic disease was the most common comorbid disease, followed by diabetes (3 cases) and biliary tract disease (3 cases). Two cases were previously healthy. The most common symptom at presentation was fever. All patients presented with abnormal changes in hematology and inflammatory parameters. Cephalosporins were the most frequently used antibiotics. Ten patients had a favorable outcome after treatment; one died from complicated underlying diseases. In summary, we recommend the timely identification of NOVC strains using MALDI-TOF-MS. The suspicion of NOVC bacteremia cannot be ruled out regardless of the host's immune status. An alternative therapeutic regimen for this infection may be ß-lactam antibiotics or combined with ß-lactamase inhibitors. Regardless, the specific therapeutic regimen should be based on the antibiogram data.

BACKGROUND: Air pollution is a key public health factor with the capacity to induce diseases. The risk of ischemia heart disease (IHD) in those suffering from systemic lupus erythematosus (SLE) from air pollution exposure is ambiguous. This study aimed to: (1) determine the hazard ratio (HR) of IHD after the first-diagnosed SLE and (2) examine the effects of air pollution exposure on IHD in SLE for 12 years. METHODS: This is a retrospective cohort study. Taiwan's National Health Insurance Research Database and Taiwan Air Quality Monitoring data were used in the study. Cases first diagnosed with SLE in 2006 cases without IHD were recruited as the SLE group. We randomly selected an additional sex-matched non-SLE cohort, four times the size of the SLE cohort, as the control group. Air pollution indices by residence city per period were calculated as the exposure. Life tables and Cox proportional risk models of time-dependent covariance were used in the research. RESULTS: This study identified patients for the SLE group (n = 4,842) and the control group (n = 19,368) in 2006. By the end of 2018, the risk of IHD was significantly higher in the SLE group than in the control group, and risks peaked between the 6th and 9th year. The HR of incidence IHD in the SLE group was 2.42 times that of the control group. Significant correlations with risk of developing IHD were noted for sex, age, CO, NO2, PM10, and PM2.5, of which PM10 exposure had the highest risk of IHD incidence. CONCLUSIONS: Subjects with SLE were at a higher risk of IHD, especially those in the 6th to 9th year after SLE diagnosis. The advanced cardiac health examinations and health education plan should be recommended for SLE patients before the 6th year after SLE diagnosed.
RESUMEN
BACKGROUND: Despite a public information campaign "To Break the Myth of Fever", nurses continued to overtreat fever. This study hypothesized that the campaign lacked the detailed rationale essential to alter nurses' attitudes and behaviors. AIM: To evaluate the effect of the educational program on nurses' knowledge, attitudes, and behaviors related to fever management. DESIGN: A randomized experimental design using a time series analysis. METHODS: A random sample of 58 medical/surgical nurses was evenly divided into an intervention and a control group. The intervention group received an educational program on fever and fever management. Both groups completed a pretest and four posttests using investigator-developed instruments: a questionnaire on knowledge and attitudes about fever management and a fever treatment checklist to audit charts. RESULTS: The intervention group had markedly higher knowledge scores and reduced use of ice pillows at all four posttests, as well as lower use of antipyretics overall, except for the first posttest, despite no sustained change in attitude. CONCLUSIONS: An educational program for fever management can effectively improve clinical nurses' knowledge and attitudes about fever management.
RESUMEN
BACKGROUND: Functional decline and increased dependence on others are common health issues among hospitalized elderly patients. However, a well-validated screening tool for predicting functional decline in elderly patients is still lacking. The current study therefore aimed to evaluate and compare the diagnostic accuracy of the Identification of Seniors at Risk-Hospitalized Patients (ISAR-HP), Variable Indicative of Placement Risk (VIP), and Score Hospitalier d' Evaluation du Risque de Perte d'Autonomie (SHERPA) in predicting functional decline 30 days after discharge in older patients admitted to an acute hospital ward. METHODS: A prospective, longitudinal study was conducted in 197 elderly inpatients at the internal medicine ward of a teaching hospital in central Taiwan. Data were collected twice, first within 48 h after hospitalization and second via a telephone interview 30 days after hospital discharge. Variables included demographic data, Barthel Index of activities of daily living (ADL), and screening instruments. The Barthel Index was used to measure functional disability. Functional decline was defined as a decline of at least five points on the Barthel Index 30 days after discharge compared to that at pre-admission. RESULTS: Patients had a mean age of 77.7 years, with 55.7% being female. Functional decline was observed in 39.1% of all patients. The best cutoff point, sensitivity, specificity, and area under the receiver operating characteristic curve were 2.5, 96.1%, 52.5%, and 0.751 for ISAR-HP; 1.5, 83.1%, 62.5%, and 0.761 for VIP; and 4.75, 89.6%, 54.2%, and 0.758 for SHERPA, respectively. CONCLUSIONS: All three instruments showed moderate diagnostic accuracy as indicated by their best cutoff points. Therefore, the results presented herein can guide health care professionals in selecting the appropriate assessment tool for predicting functional decline among hospitalized elderly patients in a clinical setting.

Purpose: Sleep disturbance is one of the major complaints among patients with diabetes. The status of diabetes control and associated complications may contribute to sleep disturbance. This study explored night time sleep and excessive daytime sleepiness in adults with type 2 diabetes and examined the association of diabetes control and associated complications on their sleep quality. Methods: A retrospective cohort study design was used. Type 2 diabetic patients (87 females and 79 males, aged 63.1 ± 10.5 years) were recruited from the outpatient clinics of the endocrine department. Sleep quality was assessed by the Pittsburg Sleep Quality Index and the Epworth Sleepiness Scale. Diabetes control and complications were obtained by retrospectively reviewing patients' medical records over 1 year prior to study enrollment. Results: 72.3% of recruited patients had poor glycemic control, and 71.1% had at least one diabetic complication. 56.0% of patients experienced poor sleep quality, and 24.1% had excessive daytime sleepiness. Those who were female (OR = 3.45) and who had ophthalmological problems (OR = 3.17) were associated with poor night time sleep quality, but if they did exercise to the point of sweating (OR = 0.48) reduced the risk of poor sleep quality. Furthermore, poor sleep quality (OR = 4.35) and having nephropathy (OR = 3.78) were associated with a higher risk of excessive daytime sleepiness. Conclusions: Sex, ophthalmological problems, nephropathy, and no exercise to the point of sweating are associated with sleep problems in patients with type 2 diabetes. Both lifestyle behaviors and diabetic complications affect sleep disturbances in patients with diabetes.

AIM: The purpose of this systematic review was to determine the extent to which the research literature indicates body temperature norms in the geriatric population. OBJECTIVES: The specific questions addressed were to examine normal body temperature values in persons 60 years of age and older; determine differences in temperature values depending on non-invasive measurement site and measurement device used; and, examine the degree and extent of temperature variability according to time of day and time of year. BACKGROUND: The traditional 'normal' temperature of 98.6 degrees F/37 degrees C may in fact be lower in older people due to the ageing process. Age-associated changes in vasomotor sweating function, skeletal muscle response, temperature perception and physical behaviours may influence the ability to maintain optimum temperature. DESIGN: A systematic literature review. METHODS: A search of multiple databases yielded 22 papers which met inclusion criteria. Studies were included which focused on temperature measurement, sampled persons 60 years of age and older, collected data from non-invasive temperature measurement sites and which used a prospective study design. Studies were independently appraised using a structured appraisal format. RESULTS: Temperature normal values by site were rectal 98.8 degrees F/37.1 degrees C, ear-based 98.3 degrees F/36.8 degrees C, urine 97.6 degrees F/36.5 degrees C, oral 97.4 degrees F/36.3 degrees C and axillary 97.1 degrees F/36.2 degrees C. Temperature exhibited a 0.7 degrees F/0.4 degrees C diurnal and 0.2 degrees F/0.1 degrees C circannual variation. CONCLUSIONS: Synthesis of data indicated that normal body temperature values in older people by sites were rectal 0.7 degrees F/0.4 degrees C, ear-based 0.3 degrees F/0.2 degrees C, oral 1.2 degrees F/0.7 degrees C, axillary 0.6 degrees F/0.3 degrees C lower than adults' acceptable value from those traditionally found in nursing textbooks. RELEVANCE TO CLINICAL PRACTICE: Given the fact that normal body temperature values were consistently lower than values reported in the literature, clinicians may need to re-evaluate the point at which interventions for abnormal temperatures are initiated.

Nocardia is a pathogen responsible for a variety of clinical infections. Here, we aimed to investigate the species distribution, clinical manifestations, and antimicrobial susceptibility of Nocardia species over 3 years in two tertiary general hospitals in China. In this retrospective study, a total of 27 Nocardia species were isolated from 27 individuals between January 2017 and December 2019. Nocardia isolates were identified to species level by mass spectrometry and 16S rRNA PCR sequencing. Clinical data were collected from medical records. Antimicrobial susceptibility was determined by the standard Broth microdilution method. The 27 patients with Nocardia infection included 12 males and 15 females with a mean age of 60.11 years. Among 27 Nocardia isolates, 7 species were identified, with the most common species being Nocardia otitidiscaviarum (40.7%). The antimicrobial susceptibility profiles varied between different Nocardia species. Notably, all Nocardia isolates were linezolid susceptible. The majority of Nocardia isolates were collected from a department of respiratory medicine (55.56%) and sputum specimen (44.44%). Pulmonary region was the most involved body site (70.37%) followed by skin (7.4%) and pleural cavity (7.4%). Most patients with Nocardia infection needed combination antibiotic therapy. Two deaths were reported during the treatment period and 24 patients achieved improvement after antibiotic therapy. The clinical manifestations of Nocardia infection and antimicrobial susceptibility profiles varied with diverse Nocardia species. Thus, the accurate identification of these species is crucial for the diagnosis and the selection of antibiotic treatment.

OBJECTIVE: This study tested the maintenance outcomes of a 3-month Sit Less, Walk More (SLWM) workplace intervention for office workers compared with usual care at 12 months from the baseline. METHOD: A quasi-experimental study was conducted in two workplaces. The intervention group (nâ=â51) received multi-component intervention and the comparison group (nâ=â50) received newsletters only. The outcomes of the study (self-reported psychosocial, physical activity, sitting, and lost productivity; objectively measured cardiometabolic biomarkers) were compared at baseline, 3, and 12 months. RESULTS: Generalized estimating equations analyses found that the intervention group had significant improvements in self-regulation for sitting less and moving more (Pâ=â0.017), walking (Pâ=â0.003), weight (Pâ=â0.013), waist circumference (Pâ=â0.002), and insulin (Pâ=â0.000) at 12 months compared with the comparison group. CONCLUSION: The SLWM intervention was effective in improving self-regulation, walking, and some cardiometabolic biomarkers in office workers.

OBJECTIVE: To investigate the expression of alpha-tubulin and gamma-tubulin, 2 kinds of centrosome proteins, in premalignant lesion and carcinoma of breast and the significance thereof. METHODS: Forty specimens of premalignant lesions of breast, 40 specimens of infiltrating ductal carcinoma of breast, 40 specimens of intraductal carcinoma (IDC), and 30 specimens of normal breast tissues were obtained during operation. Immunohistochemistry was used to analyze the protein expression of alpha-tubulin and gamma-tubulin, and the percentages of ki67 positive cells. Western blotting was used to examine the mRNA expression of alpha-tubulin and gamma-tubulin. RESULTS: The protein and mRNA expression values of alpha-tubulin and gamma-tubulin in breast carcinoma were higher than those in the premalignant lesions and normal breast tissues with significant differences between the premalignant lesions and normal breast torques and without significant differences between infiltrating ductal carcinoma of breast and IDC. The ki67 positive rates of the infiltrating ductal carcinoma of breast group, IDC group, premalignant lesion group, and normal breast tissues group were 16.0%, 37.0%, 53.6%, and 67.8% (P = 0.001). A positive correlation existed between the expression of alpha-tubulin and the expression of gamma-tubulin in the same case and the same group (all P = 0.00) and there was no significant correlation between the expression of alpha-tubulin and the expression of gamma-tubulin in the same case and the same group (all P > 0.05). Both the expression of alpha-tubulin and the expression of gamma-tubulin were significantly associated with the prognosis. CONCLUSIONS: Centrosome protein is one of the distinct phenotypes of breast cancer cells. Aberration of centrosome proteins may be used to screen high risk cases of breast carcinoma and to estimate the prognosis.

PURPOSE: Models of health influence providers' practice and delivery of health care. This study surveyed a random sample of providers to determine if health care providers from mainstream medicine (MM), integrative medicine (IM), and complementary and alternative medicine (CAM) hold mutually exclusive models of health or combine notions from models thought to be contradictory. METHODS: A survey was created through qualitative research, piloted, and mailed to a wide variety of MM, IM, and CAM health care professionals. RESULTS: All providers combined various models and definitions of health. Most utilized the biomedical approach to some extent. Balance (holistic model) and functioning in daily life were essential to most respondents' models of health, disease, and healing. Close communication between MM and CAM systems was preferred over complete separation or a single system. CONCLUSIONS: Many providers of all types combine widely disparate components in their definitions of health, providing keys for improving communication.

Breast tissue sections were examined by means of confocal Raman spectroscopy with an excitation wavelength of 633 nm. Acquired using a microscopic mapping approach with the sample volume of -2 microm3, these spectra were compared with the ones of the commercially available actin, DNA, collagen (type I), triolein etc. Some spectra were distinguished and identified and characterize the morphological elements like cell cytoplasm, extracellular matrix etc. The cell nucleus spectrum was also obtained by K-means cluster analysis. The correlation analysis showed that the spectrum from a morphological element is highly correlated with that from the corresponding purified chemical. The spectroscopic characterization of these morphological elements was then investigated. This study is helpful to understanding the chemical/morphological basis of the Raman spectrum and designing the Raman microspectroscopic model of human breast tissue.

BACKGROUND: Diabetes mellitus (DM) remains a major health problem worldwide. Several clinical trials have shown the superiority of the Traditional Chinese Medicine in delaying or reversing the development and progression of DM. This study aimed to evaluate the efficacy of Jinlida (JLD) granule, a Chinese herbal recipe, in the treatment of impaired glucose tolerance (IGT) and its effect on the prevention of DM. METHODS: Sixty-five IGT patients were randomized to receive one bag of JLD granules three times daily (JLD group, n = 34) or no drug intervention (control group, n = 31) for 12 weeks. Oral glucose tolerance test, glycated hemoglobin A1c (HbA1c), body mass index, blood lipids levels, fasting insulin, and insulin resistance calculated using homeostatic model assessment (HOMA-IR) of all the patients were observed and compared before and after the treatment. RESULTS: Sixty-one participants completed the trial (32 in JLD group and 29 in the control group). There were statistically significant decreases in HbA1c (P < 0.001), 2-h plasma glucose (P < 0.001), and HOMA-IR (P = 0.029) in JLD group compared with the control group after 12 weeks of treatment. After 12 weeks of treatment, two (6.9%) patients returned to normal blood glucose, and five (17.2%) patients turned into DM in control group, while in the JLD group, 14 (43.8%) returned to normal blood glucose and 2 (6.2%) turned into DM. There was a significant difference in the number of subjects who had normal glucose at the end of the study between two groups (P = 0.001). CONCLUSIONS: JLD granule effectively improved glucose control, increased the conversion of IGT to normal glucose, and improved the insulin resistance in patients with IGT. This Chinese herbal medicine may have a clinical value for IGT.

BACKGROUND: Fever is a complex and major sign of a patient's acute response to infection. However, analysis of the risks and benefits associated with the change in body temperature of an infected host remains controversial. OBJECTIVE: To examine the relationship between the intensity of the change in body temperature and the mortality of patients with hospital-acquired bacteremia. DESIGN: A prospective observational study. METHOD: Subjects were hospitalized adult patients who developed clinical signs of infection 48 hr or more after admission and had documented bacterial growth in blood culture. The maximum body temperature (maxTe) during the early period of infection measurements (i.e., the day before, the day of, and 2 days after the day of blood culture) was used to indicate the intensity of the body temperature response. Patients were categorized as discharged alive or died in hospital. Cox regression analysis was employed to analyze the data. RESULTS: The cohort consisted of 502 subjects. The mean maxTe of subjects was 38.6°C, and 14.9% had a maxTe lower than 38.0°C. The in-hospital mortality rate was 18.9%. The highest in-hospital mortality was found in subjects with a maxTe lower than 38°C (30.7%). Multivariate Cox regression analysis determined that the maxTe and the severity of comorbidity are the two variables associated with in-hospital mortality. CONCLUSIONS: Lack of a robust febrile response may be associated with greater risk of mortality in patients with bacteremia. Clinicians must be vigilant in identifying patients at risk for a blunted febrile response to bacteremia for more intensive monitoring.
