Objectives
In the Fluid and Catheter Treatment Trial (FACTT) of the National
Institutes of Health Acute Respiratory Distress Syndrome Network, a
conservative fluid protocol (FACTT Conservative) resulted in a lower
cumulative fluid balance and better outcomes than a liberal fluid protocol
(FACTT Liberal). Subsequent Acute Respiratory Distress Syndrome Network
studies used a simplified conservative fluid protocol (FACTT Lite). The
objective of this study was to compare the performance of FACTT Lite, FACTT
Conservative, and FACTT Liberal protocols.
Design
Retrospective comparison of FACTT Lite, FACTT Conservative, and FACTT
Liberal. Primary outcome was cumulative fluid balance over 7 days. Secondary
outcomes were 60-day adjusted mortality and ventilator-free days through day
28. Safety outcomes were prevalence of acute kidney injury and new
shock.
Setting
ICUs of Acute Respiratory Distress Syndrome Network participating
hospitals.
Patients
Five hundred three subjects managed with FACTT Conservative, 497
subjects managed with FACTT Liberal, and 1,124 subjects managed with FACTT
Lite.
Interventions
Fluid management by protocol.
Measurements and Main Results
Cumulative fluid balance was 1,918 ± 323 mL in FACTT Lite,
−136 ±491 mL in FACTT Conservative, and 6,992 ± 502
mL in FACTT Liberal (p < 0.001). Mortality was not
different between groups (24% in FACTT Lite, 25% in FACTT
Conservative and Liberal, p = 0.84).
Ventilator-free days in FACTT Lite (14.9 ±0.3) were equivalent to
FACTT Conservative (14.6±0.5) (p = 0.61)
and greater than in FACTT Liberal (12.1 ±0.5, p
< 0.001 vs Lite). Acute kidney injury prevalence was 58% in
FACTT Lite and 57% in FACTT Conservative (p
= 0.72). Prevalence of new shock in FACTT Lite (9%) was
lower than in FACTT Conservative (13%) (p =
0.007 vs Lite) and similar to FACTT Liberal (11%)
(p = 0.18 vs Lite).
Conclusions
FACTT Lite had a greater cumulative fluid balance than FACTT
Conservative but had equivalent clinical and safety outcomes. FACTT Lite is
an alternative to FACTT Conservative for fluid management in Acute
Respiratory Distress Syndrome.
Visceral leishmaniasis (VL) is a re-emerging zoonosis of worldwide distribution. Monocyte chemotactic protein-1 (MCP-1) and malondialdehyde (MDA) are inflammation biomarkers that have never been investigated in VL. The aim of this study is to investigate the association between renal abnormalities and inflammation biomarkers in VL. This study is a preliminary prospective study with 16 VL adult patients evaluated before treatment compared with a group of 13 healthy volunteers and 5 VL patients evaluated after treatment. Urinary concentration and acidification tests were performed. MCP-1 and MDA were quantified in urine. Urinary concentration deficit was found in all VL patients before (100%) and four VL patients after (80%) treatment. Urinary acidification deficit was found in nine cases before (56.2%) and two cases after (40%) treatment. Urinary MCP-1 (374 ± 359 versus 42 ± 29 pg/mg creatinine, P = 0.002) as well as urinary MDA (5.4 ± 2.6 versus 2.0 ± 0.8 μmol/mL) showed significant differences between VL patients and controls. These data show that VL patients present urinary concentration and acidification deficit, which can persist even after specific treatment. Urinary MCP-1 and MDA are elevated in patients with VL, which suggests renal inflammation and incipient renal damage.
Depression is frequent in end-stage renal disease (ESRD) and predicts mortality in dialysis patients. The aim of this study was to investigate the occurrence of depression among patients on hemodialysis. We conducted an observational cross-sectional study at two hemodialysis centres in the metropolitan area of Fortaleza, Ceará, Brazil, between September and October 2010. The occurrence of depression was evaluated according to Beck Depression Inventory II. Among 148 patients interviewed, the mean age was 46 ± 13 years and 54% were male. The average time on dialysis was 5.3 ± 5.2 years. Depression was found in 101 (68.2%) cases. Depression was classified as mild (49.5%), moderate (41.5%) and severe (9%). Only 15.5% had prior depression diagnosis. Follow-up with Psychologist was being done in only 32.4% of cases. Patients with depression had a higher frequency of antidepressant use (20.7% vs. 4.2%, p=.01) and benzodiazepines (33.6% vs. 8.5%, p=.001). Among patients using antidepressant, improvement of symptoms was reported by 81.6%. Depression is one potentially modifiable risk factor in ESRD. The investigation and multidisciplinary approach of depression should be part of routine evaluation of patients on dialysis.
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.
