NAC administration prevents the derangement in thyroid hormone concentrations commonly occurring in the acute phase of acute myocardial infarction, indicating that oxidative stress is involved in the NTIS pathophysiology.
Lemierre's syndrome is characterized by acute oropharyngeal infection, complicated by internal jugular venous thrombosis secondary to septic thrombophlebitis, and by metastatic infections in various distant organs-most commonly in the lungs. We report a case of Lemierre's syndrome in a 56-year-old female who presented with right-sided neck mass and fever. Right internal jugular venous thrombosis was demonstrated on an ultrasound. A computed tomography scan of the chest revealed multiple opacities throughout both lungs. An open surgical biopsy was performed due to suspicion of pulmonary metastases. Anatomopathological examination revealed septic emboli in lung parenchyma. Retrospectively, the patient reported a history of pharyngitis two weeks prior to hospitalization. After the diagnosis had been made, the patient was treated with broad-spectrum antibiotics (cefuroxime for 7 days and azithromycin for 5 days; subsequently, because fever persisted, cefepime for 7 days). One month later, a computed tomography scan of the chest revealed resolution of the opacities.
Objective
To assess the relationship between time to focus clearance and hospital mortality in patients with sepsis and septic shock.
Methods
This was an observational, single-center study with a retrospective analysis of the time to clearance of abdominal septic focus. Patients were classified according to the time to focus clearance into an early (≤ 12 hours) or delayed (> 12 hours) group.
Results
A total of 135 patients were evaluated. There was no association between time to focus clearance and hospital mortality (≤ 12 hours versus > 12 hours): 52.3% versus 52.9%, with p = 0.137.
Conclusion
There was no difference in hospital mortality among patients with sepsis or septic shock who had an infectious focus evacuated before or after 12 hours after the diagnosis of sepsis.
Objective To assess the performance of central venous oxygen saturation, lactate, base
deficit, and C-reactive protein levels and SOFA and SWIFT scores on the day of
discharge from the intensive care unit as predictors of patient readmission to the
intensive care unit. Methods This prospective and observational study collected data from 1,360 patients who
were admitted consecutively to a clinical-surgical intensive care unit from August
2011 to August 2012. The clinical characteristics and laboratory data of
readmitted and non-readmitted patients after discharge from the intensive care
unit were compared. Using a multivariate analysis, the risk factors independently
associated with readmission were identified. Results The C-reactive protein, central venous oxygen saturation, base deficit, and
lactate levels and the SWIFT and SOFA scores did not correlate with the
readmission of critically ill patients. Increased age and contact isolation
because of multidrug-resistant organisms were identified as risk factors that were
independently associated with readmission in this study group. Conclusion Inflammatory and perfusion parameters were not associated with patient
readmission. Increased age and contact isolation because of multidrug-resistant
organisms were identified as predictors of readmission to the intensive care
unit.
We performed a systematic review and meta-analysis to comprehensively determine the prevalence and the prognostic role of nonthyroidal illness syndrome (NTIS) in critically ill patients. We included studies that assessed thyroid function by measuring the serum thyroid hormone level and in-hospital mortality in adult septic patients. Reviews, case reports, editorials, letters, animal studies, duplicate studies, and studies with irrelevant populations and inappropriate controls were excluded. A total of 6869 patients in 25 studies were included. The median prevalence rate of NTIS was 58% (IQR 33.2-63.7). In univariate analysis, triiodothyronine (T3) and free T3 (FT3) levels in non-survivors were relatively lower than that of survivors (8 studies for T3; standardized mean difference (SMD) 1.16; 95% confidence interval (CI), 0.41–1.92; I2 = 97%; P < 0.01). Free thyroxine (FT4) levels in non-survivors were also lower than that of survivors (12 studies; SMD 0.54; 95% CI, 0.31–0.78; I2 = 83%; P < 0.01). There were no statistically significant differences in TSH levels between non-survivors and survivors. NTIS was independently associated with increased risk of mortality in critically ill patients (OR = 2.21, 95% CI 1.64.- 2.97, I2 = 65% p < 0.01) The results favor the concept that decreased thyroid function might be associated with a worse outcome in critically ill patients. Hence, the measurement of TH could provide prognostic information on mortality in adult patients admitted to ICU.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
