RESUMO
OBJECTIVE: The objective of this article is to investigate clinical presentations and outcomes of systemic lupus erythematosus (SLE) patients with infection admitted to the intensive care unit (ICU). METHODS: SLE patients with infection, SLE patients with noninfectious causes, and non-SLE patients with infection were identified from the Cooper University Hospital Project IMPACT database between 2002 and 2010. We examined demographic data, APACHE II scores, physiologic data, laboratory data, length of stay in the ICU and hospital, and mortality of the three groups. RESULTS: Twenty-five SLE patients with infection, 45 SLE patients with noninfectious causes, and 1466 non-SLE patients with infection were included in the study. SLE patients with infection had higher APACHE II scores, higher maximum temperature, higher minimum and maximum heart rate (HR), lower minimum and maximum systolic blood pressure (SBP), and longer ICU length of stay in comparison to SLE patients with noninfectious causes. There were no statistical differences in white blood cell (WBC) count. SLE patients with infection had a higher mortality compared to SLE patients with noninfectious causes. There was no difference in mortality between SLE patients with infection and non-SLE patients with infection. CONCLUSION: SLE patients with infection in the ICU had a higher mortality and a higher APACHE II score compared to SLE patients with noninfectious causes in the ICU. Their physiologic signs including temperature, HR, and SBP were more reflective of infection than their WBC count.

BACKGROUND AND OBJECTIVES: Packed red blood cell transfusion has been associated with increased infection in a variety of critically ill patient populations. We evaluated the microbiology and time course of infection in transfused patients in the intensive care unit (ICU) as no data exist on these parameters. MATERIALS AND METHODS: We performed a retrospective review of data for all patients admitted to a 24-bed medical-surgical ICU at Cooper University Hospital from July 2003 to September 2006 and entered in the Project Impact database. RESULTS: A total of 2432 patients were admitted during the study period, of which 609 underwent transfusion. Transfused patients were more likely to develop a nosocomial infection (10.5% vs. 4.9%, P < 0.001). ICU and hospital length of stay were longer in the transfused group (P < 0.001 for both). Mortality was also greater (13.1% vs. 8.7%, P = 0.001). Transfused patients had a shorter time from hospital admission to first infection (P < 0.001) and ICU admission to first infection (P < 0.001). Multivariate analysis confirmed transfusion as an independent risk factor for infection, mortality, hospital and ICU length of stay. Methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococcus and Acinetobacter occurred more often in transfused patients. Acinetobacter accounted for a disproportionate share of infections among transfused patients (P < 0.001). CONCLUSIONS: Transfused ICU patients have a higher incidence of nosocomial infection and worse outcomes. Transfused patients had a shorter onset of infection. Acinetobacter infection appears to be particularly common among these patients. Further investigation is merited to better elucidate the mechanism for these findings and their therapeutic and clinical implications.

In a six week, double-blind, predictive, clinical study 224 neurotic and anxious outpatients were randomly assigned to treatment with diazepam (Valium) of placebo and weekly brief psychotherapy administered by experienced psychiatrists. Although diazepam was significantly more effective than placebo for the first week of treatment, it accounted for only 1-4% of the outcome variance, while nonspecific variables contributed 11-22%. After the first revisit and at endpoint, only nonspecific variables accounted for outcome variance ranging from 20 to 26% over the four outcome measures. According to physicians' global and scaled ratings of improvement, diazepam had a treatment advantage (p less than 0.01-0.05) over placebo at the end of the first week of treatment for both the total and completed samples, but not thereafter. According to patients' global ratings of improvement, diazepam was moderately superior (p less than 0.05) to placebo for the total sample only at the end of the first week of treatment and modestly better (p less than 0.10) than placebo for the completed sample on a highly reliable measure of reported anxiety at the same time point. However, patient ratings did not indicate an advantage for diazepam at any of the six points of observation on global ratings of improvement for the completed sample and on reported anxiety for the total sample.

AIM: To investigate whether the prevalence GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0 and T0M0) are increased in certain spontaneous optic neuropathies. METHODS: We compared the prevalence of GSTT1 and GSTM1 deletion genotypes in 108 Arab patients with optic neuritis (ON, 26 patients), LHON-like optic neuropathy (LLON, 35 patients), sporadic bilateral optic neuropathy in children (SBON, 21 patients) and non-arteritic ischaemic optic neuropathy (NAION, 26 patients) to 120 ethnicity-matched controls. Genotypes were determined by multiplex polymerase chain reaction. RESULTS: All three GST deletion genotypes were significantly more prevalent in the entire optic neuropathy group than in controls. When patients were stratified by optic neuropathy type, the prevalence of at least one deletion genotype was significantly increased in each type of optic neuropathy. CONCLUSIONS: These results imply that GST malfunction in the setting of GST deletion genotypes may interfere with metabolism of oxidative intermediates and may exacerbate direct or indirect pathological effects of oxidative stress on the optic nerve in the setting of these spontaneous optic neuropathies. It is possible that these GST polymorphisms are risk factors for the types of optic neuropathies investigated here.

This retrospective cohort mortality study examined 2,467 workers in lubrication products blending and packaging (B&P) operations at two refineries of Mobil Corporation between January 1, 1945 and December 31, 1978. Ninety-seven percent were male. Compared with U.S. males, there were significantly fewer deaths observed among males due to all causes, external causes, and diseases of the circulatory, respiratory, digestive, and genitourinary systems. Deaths observed from all cancer were fewer than expected, although not statistically significant. No statistically significant excess cause-specific mortality occurred at B&P facilities combined or separately. Nonsignificant increases in mortality were observed for cancers of the stomach, large intestine, prostate, the category of "other lymphatic tissue" cancer, and leukemia and aleukemia. Analyses demonstrated a statistically significant pattern of increasing SMR with employment duration for "other lymphatic tissue" cancer. Within the highest cumulative duration of employment category, the excess was confined to workers after 30 or more years since first employment. Although the interpretation of cancer mortality patterns is limited due to small numbers of deaths, the absence of associations with specific B&P departments is evidence against a causal interpretation.
