This study examines the impact of intensive family preservation services (IFPS) on racial disproportionality of placement into out-of-home care. A large sample (N = 30,060) was partitioned on the basis of race, risk, and services received. The probability of placement is examined as a function of these variables. High-risk minority children receiving traditional services are at higher risk of placement than white children are, but minority children receiving IFPS are less likely to be placed than white children are. When only minority children are examined, those receiving IFPS are less likely to be placed than those receiving traditional services are. IFPS is associated with a reduction in racial disproportionality of out-of-home placement among high-risk families. Within-race analysis suggests that IFPS may mitigate racial disparity in out-of-home placement existing in the remainder of the child welfare population that receives traditional services.

Copper is an essential cofactor in many enzymatic reactions vital to the normal function of the hematologic, vascular, skeletal, antioxidant, and neurologic systems. Copper deficiency in the United States is believed to be relatively rare but has been described in the setting of zinc supplementation, myelodysplastic syndrome, use of parenteral nutrition and chronic tube feeding, and in various malabsorptive syndromes, including following gastrectomy and gastric bypass surgery. Features of copper deficiency include hematologic abnormalities (anemia, neutropenia, and leukopenia) and myeloneuropathy; the latter is a rarer and often unrecognized complication of copper deficiency. We here describe two patients who presented with severe gait abnormalities and anemia combined with neutropenia several years after roux-en-Y gastric bypass (RYGB) surgery for obesity who were found to be severely copper deficient. Intravenous copper repletion resulted in the rapid correction of hematologic indices; combined intravenous and oral copper supplementation and eventual oral copper supplements alone normalized serum copper levels in each patient, but resulted in only partial resolution of the neurologic deficits. This report serves to alert physicians of the association between RYGB procedures and subsequent copper deficiency in order to avoid diagnostic delays and to improve treatment outcomes.Obesity (2009) doi:10.1038/oby.2008.614.

BACKGROUND: Nosocomial infections are an important cause of morbidity and mortality in the surgical intensive care unit (SICU). Clinical benefits of glutamine-supplemented parenteral nutrition may occur in hospitalized surgical patients, but efficacy data in different surgical subgroups are lacking. The objective was to determine whether glutamine-supplemented parenteral nutrition differentially affects nosocomial infection rates in selected subgroups of SICU patients. METHODS: This was a double-blind, randomized, controlled study of alanyl-glutamine dipeptide-supplemented parenteral nutrition in SICU patients requiring parenteral nutrition and SICU care after surgery for pancreatic necrosis, cardiac, vascular, or colonic surgery. Subjects (n = 59) received isocaloric/isonitrogenous parenteral nutrition, providing 1.5 g/kg/d standard glutamine-free amino acids (STD-PN) or 1.0 g/kg/d standard amino acids + 0.5 g/kg/d glutamine dipeptide (GLN-PN). Enteral feedings were advanced as tolerated. Nosocomial infections were determined until hospital discharge. RESULTS: Baseline clinical/metabolic data were similar between groups. Plasma glutamine concentrations were low in all groups and were increased by GLN-PN. GLN-PN did not alter infection rates after pancreatic necrosis surgery (17 STD-PN and 15 GLN-PN patients). In nonpancreatic surgery patients (12 STD-PN and 15 GLN-PN), GLN-PN was associated with significantly decreased total nosocomial infections (STD-PN 36 vs GLN-PN 13, P <.030), bloodstream infections (7 vs 0, P <.01), pneumonias (16 vs 6, P <.05), and infections attributed to Staphylococcus aureus (P <.01), fungi, and enteric Gram-negative bacteria (each P <.05). CONCLUSIONS: Glutamine dipeptide-supplemented parenteral nutrition did not alter infection rates following pancreatic necrosis surgery but significantly decreased infections in SICU patients after cardiac, vascular, and colonic surgery.

BACKGROUND: Glutamine (Gln) may become conditionally indispensable during critical illness. The short-term metabolic effects of enteral versus parenteral Gln supplementation are unknown in this clinical setting. OBJECTIVES: We studied metabolic effects of intravenous (IV) alanyl-Gln dipeptide (AG) supplementation and enteral (EN) AG supplementation on plasma Gln concentration, antioxidant status, plasma lymphocyte subset number, gut permeability and nitrogen balance in adult critically ill patients requiring tube feeding compared to a control group not receiving Gln supplementation. METHODS: In a double-blind, pilot clinical trial, 44 medical and surgical ICU patients received identical Gln-free tube feedings 24h/day and were randomized to either isonitrogenous control (n=15), EN AG (n=15) or IV AG (n=14) groups (AG). Twelve patients were discontinued from the study. The goal AG dose was 0.5g/kg/day. Biochemical and metabolic endpoints were measured at baseline and on day 9 (plasma Gln, antioxidant indices, lymphocyte subsets; serum IGF-1 and IGF-binding protein-3; intestinal permeability). Nitrogen balance was determined between study days 6 and 8. RESULTS: Illness severity indices, clinical demographics, enteral energy and nitrogen intake and major biochemical indices were similar between groups during study. Plasma Gln was higher in the IV AG (565+/-119muM, mean+/-SEM) vs the EN AG (411+/-27muM) group by day 9 (p=0.039); however, subjects in the IV AG group received a higher dose of AG (IV AG 0.50 versus EN AG 0.32+/-0.02g/kg/day; p<0.001). EN AG subjects showed a significant increase in plasma alpha-tocopherol levels over time and maintained plasma gamma-tocopherol concentrations. There were no differences between groups for plasma concentrations of vitamin C, glutathione, malondialdehyde (MDA), T-lymphocyte subsets, intestinal permeability or nitrogen balance. CONCLUSIONS: This study showed that alanyl-Gln administration by enteral or parenteral routes did not appear to affect antioxidant capacity or oxidative stress markers, T-lymphocyte subset (CD-3, CD-4, CD-8) number, gut barrier function or whole-body protein metabolism compared to unsupplemented ICU patients requiring enteral tube feeding. Enteral Gln appeared to maintain plasma tocopherol levels in this pilot metabolic study.

OBJECTIVES: Antioxidant depletion is common in critically ill patients. This study was designed to determine the effects of parenteral nutrition (PN), with or without glutamine (Gln) supplementation, on systemic antioxidant status in adult patients after major surgery who required PN in the surgical intensive care unit (SICU) setting. METHODS: Fifty-nine patients in the SICU who required PN after pancreatic surgery or cardiac, vascular, or colonic (non-pancreatic) surgery were randomized in a double-blinded study to receive standard PN (Gln-free) or Gln-supplemented PN (Gln-PN) in which Gln was provided as alanyl-Gln dipeptide. Conventional PN vitamin and mineral doses were administered to all subjects. Plasma concentrations of the antioxidant glutathione (GSH) and the antioxidant nutrients alpha-tocopherol, vitamin C, and zinc were determined at baseline (initiation of study PN) and again after 7 d of study PN. Data were analyzed for the total study cohort and within the pancreatic surgery and non-pancreatic (cardiac, vascular, and colonic) surgery patient subgroups. RESULTS: Mean plasma antioxidant concentrations were within or slightly below the normal ranges at baseline. However, a larger percentage of patients demonstrated below-normal baseline plasma concentrations of GSH (59%), vitamin C (59%), and zinc (68%), respectively. A smaller percentage of patients exhibited below-normal plasma alpha-tocopherol levels (21%). Study PN significantly improved plasma zinc levels in the entire study group and in each surgical subgroup. Gln-PN significantly improved the change in plasma levels of reduced GSH from baseline to day 7 in the non-pancreatic surgery patients (PN -0.27 muM versus Gln-PN +0.26 muM, P < 0.03). CONCLUSION: Low plasma levels of key antioxidants were common in this group of patients in the SICU despite administration of PN containing conventional micronutrients. Compared with standard PN, Gln-supplemented PN improved plasma GSH levels in patients in the SICU after cardiac, vascular, or colonic operations.

This study examined the psychosocial functioning of 100 adolescent females (ages 12-17) sentenced to secure care in a southeastern state and the impact of gender-specific, cognitive-behavioral therapy (CBT) intervention on the psychosocial functioning of subjects who reported a history of sexual abuse. The Multidimensional Adolescent Assessment Scale (MAAS) was used to assess psychosocial functioning. Pre-test scores on the MAAS revealed significantly higher scores on 12 of 16 dimensions of psychosocial functioning and higher rates of serious criminal behavior for youth who subsequently disclosed sexual abuse histories as compared to those without such histories. At post-test, statistically significant improvements in psychosocial functioning were observed on 14 of 16 MAAS subscales for those who received the CBT intervention. Thus, incarcerated female adolescents who reported a history of sexual abuse demonstrated more impairment in their functioning as compared to those without a reported history of sexual abuse and responded positively to gender-specific, CBT-based intervention.

OBJECTIVE: Heat shock protein 70 (HSP-70) is protective against cellular and tissue injury. Increased serum HSP-70 levels are associated with decreased mortality in trauma patients. Glutamine (Gln) administration increases serum and tissue HSP-70 expression in experimental models of sepsis. Gln has been safely administered to critically ill patients and can improve clinical outcomes, but the effect of Gln administration on HSP-70 expression in humans is unknown. We examined whether Gln-supplemented parenteral nutrition (PN) increases serum HSP-70 levels in critically ill patients. DESIGN AND SETTING: Randomized, controlled, double-blind study in surgical intensive care units (SICU) in a university hospital. PATIENTS: 29 patients admitted to the SICU and requiring PN for more than 7 days. INTERVENTIONS: Patients received either Gln-PN (containing alanyl-glutamine dipeptide; 0.5 g/kg per day; n=15) or standard Gln-free PN (control-PN) that was iso-nitrogenous to Gln-PN (n=14). Serum HSP-70 concentrations were measured at enrollment and at 7 days. Clinical outcome measures were also determined. RESULTS: HSP-70 concentrations were unchanged in control-PN subjects from baseline to day 7. In marked contrast, Gln-PN subjects demonstrated significantly higher (3.7-fold) serum HSP-70 concentrations than control subjects. In Gln-PN patients there was a significant correlation between increases in HSP-70 levels over baseline and decrease in ICU length of stay. CONCLUSIONS: Gln-PN significantly increases serum HSP-70 in critically ill patients. The magnitude of HSP-70 enhancement in Gln-treated patients was correlated with improved clinical outcomes. These data indicate the need for larger, randomized trials of the Gln effect on serum and tissue HSP-70 expression in critical illness and relationship to clinical outcomes.

PURPOSE: Manipulation of infection calculi (struvite and calcium apatite) can cause the sepsis syndrome due to endotoxemia or bacteremia. We sought to determine whether concentrations of endotoxin sufficient to produce the sepsis syndrome could be embedded in renal infection stones. MATERIALS AND METHODS: Fragments of infection and noninfection renal calculi were processed and assayed for endotoxin concentration. Endotoxin concentrations, recorded as endotoxin units per gm. calculus, were converted to ng.(10 endotoxin units = 1 ng.). Urine culture results were available for some patients with infection stones. RESULTS: A total of 34 renal calculi (16 infection and 18 noninfection) were evaluated. The composition of 62.5% of the infection stones was struvite, whereas 50% of the noninfection stones were calcium oxalate monohydrate. Mean endotoxin concentration in infection calculi was 12,223 ng./gm. stone (range 0.6 to 50,000), compared to 340.3 ng./gm. stone (range 0 to 3,490) in noninfection calculi. The endotoxin content difference was significant (p = 0.001). Urine culture results available from 9 patients with infection stones did not correlate with endotoxin concentrations. CONCLUSIONS: Large endotoxin concentrations can be found in renal infection calculi. Noninfection stones can contain endotoxin but in much lower amounts. Massive endotoxin release could occur with infection stone manipulation, possibly producing increased serum endotoxin concentrations similar to those seen in gram-negative sepsis. Anti-endotoxin strategies may be beneficial in preventing and treating stone induced endotoxemia and the sepsis syndrome.

OBJECTIVE To evaluate the efficacy of intravenous erythromycin as a method to facilitate feeding tube placement into the small intestine in critically ill patients.DESIGN Double blind, randomized, controlled trial.SETTING Medical and surgical intensive care units in an academic medical center.PATIENTS Prospective cohort of 36 consecutive adults requiring intensive care unit care and enteral tube feeding for nutritional support.INTERVENTION Infusion of a single dose of intravenous erythromycin (500 mg) or saline before placement of 10-Fr feeding tubes using a standardized active bedside protocol.MEASUREMENTS AND MAIN RESULTS We determined the success rate of feeding tube placement into or beyond the second portion of the duodenum and the time required for this procedure by experienced nurses. The feeding tube was considered to be postpyloric when the tip was in the second portion of the duodenum or beyond. The predictive value of a serial step-up in gastrointestinal aspirate pH from < or = 5.0 to > or = 6.0 was also determined. Use of intravenous erythromycin significantly improved the rate of feeding tube placement into the duodenum or jejunum (erythromycin group, 13 of 14 patients or 93% vs. the control group, 12 of 22 patients or 55%; p <.03). Erythromycin administration also significantly decreased the procedure time from 25 +/- 3 to 15 +/- 2 mins (p <.04). Feeding tube placement into either duodenum or jejunum was confirmed in all 18 patients with a pH step-up from < or = 5.0 to > or = 6.0. CONCLUSION: A single bolus dose of intravenous erythromycin facilitates active bedside placement of postpyloric feeding tubes in critically ill adult patients.

BACKGROUND: Chemotherapy and radiation therapy result in increased free radical formation and depletion of tissue antioxidants. It is not known whether parenteral nutrition (PN) administered during bone marrow transplantation (BMT) supports systemic antioxidant status. OBJECTIVE: The aims of the study were to determine 1) whether high-dose chemotherapy decreases concentrations of major circulating antioxidants in patients undergoing BMT and 2) whether administration of standard PN maintains systemic antioxidant concentrations compared with PN containing micronutrients and minimal lipids alone. DESIGN: Twenty-four BMT patients were randomly assigned to receive either standard PN containing conventional amounts of dextrose, amino acids, micronutrients, and lipid (120 kJ/d) or a solution containing only micronutrients (identical to those in standard PN) and a small amount of lipid (12 kJ/d). Plasma antioxidant status was measured before conditioning therapy and serially at days 1, 3, 7, 10, and 14 after BMT. RESULTS: Plasma glutathione (GSH) and alpha- and gamma-tocopherol concentrations decreased and the GSH redox state became more oxidized after conditioning chemotherapy. Plasma cysteine concentrations were unchanged, whereas cystine concentrations increased. Plasma vitamin C and zinc concentrations and GSH peroxidase activity increased over time. Plasma alpha-tocopherol concentrations were lower in patients given standard PN. There were no differences in other plasma antioxidants between groups. CONCLUSIONS: A significant decline in GSH-glutathione disulfide, cysteine-cystine, and vitamin E status occurs after chemotherapy and BMT. Standard PN does not improve antioxidant status compared with administration of micronutrients alone. Further evaluation of PN formulations to support patients undergoing high-dose chemotherapy and BMT are needed.
