Effect of nandrolone decanoate on skeletal muscle repair.

This study analyzed the effect of nandrolone decanoate (ND) on muscle repair and the expression of myogenic regulatory factors following cryoinjury in rat skeletal muscle. Adult male Wistar rats were randomly divided into 4 groups: control group, sham group, cryoinjured group treated with ND and non-injured group treated with ND. Treatment consisted of subcutaneous injections of ND (5 mg/kg) twice a week. After sacrifice, the tibialis anterior muscle was removed for the isolation of total RNA and analysis of myogenic regulatory factors using real-time PCR as well as morphological analysis using the hematoxylin-eosin assay. There was a significant increase in MyoD mRNA after 7 days and in myogenin mRNA after 21 days in the cryoinjured ND group in comparison to other groups in the same period. The morphological analysis revealed no edema or myonecrosis after 7 days as well as no edema or inflammatory infiltrate after 14 days in the cryoinjured ND group. In conclusion the anabolic steroid nandrolone decanoate can modulate the muscle repair process in rats following cryoinjury by influencing the expression of regulatory myogenic factors and phases of muscle repair.

Renal evaluation in women with preeclampsia.

BACKGROUND/AIMS: Preeclampsia (PE) is a cause of glomerulopathy worldwide. Urinary retinol-binding protein (RBP) is a marker of proximal tubular dysfunction, albuminuria is an endothelial injury marker, urine protein:creatinine ratio (PCR) may have a predictive value for renal disease later in life, and, recently, podocyturia has been proposed as a sensitive tool in pregnancy, but it needs to be tested. The aim of this study was to evaluate renal involvement in PE and healthy pregnancy. METHODS: Case-control study with 39 pregnant women assessed after 20 weeks of gestation (25 in the control group, CG, and 14 in the PE group) by performing urinary tests. RESULTS: Mean (±SD) age and gestational age of the CG were 26.9 ± 6.4 years and 37.1 ± 5.0 weeks, and of the PE group 26.4 ± 6.9 years and 30.6 ± 5.6 weeks, respectively (p = 0.001). Mean (±SD) urinary RBP (p = 0.017), albuminuria (p = 0.002), and urinary albumin concentration (UAC) ratio (p = 0.006) of the CG were 0.4 ± 0.7 mg/l, 7.3 ± 6.9 mg/l, and 8.2 ± 6.7 mg/g and of the PE group 2.0 ± 4.4 mg/l, 2,267.4 ± 2,130.8 mg/l (p = 0.002), and 3,778.9 ± 4,296.6 mg/g (p = 0.006), respectively. Mean (±SD) urine PCR in the PE group was 6.7 ± 6.1 g/g (p < 0.001). No statistical differences were found between podocyturia in the CG and PE group (p = 0.258). CONCLUSIONS: Urinary RBP, PCR, albuminuria, and UAC ratio were elevated in the PE group in comparison to the CG. Podocyturia did not predict PE.

PP019 The role of renal markers in women with and without preeclampsia: Evaluation of urinary excretion of podocytes and proteins.

INTRODUCTION: Preeclampsia (PE) is an important cause of glomerulopathy. Assessment of renal markers during pregnancy may have a predictive value for glomerular disease later in life. The early detection of PE may prevent the complications of this syndrome. OBJECTIVES: Assess the glomerular involvement in PE and in normal pregnancy by evaluating renal markers such as podocyturia and proteinuria. METHODS: Case-control study with 39 pregnant women after 20 weeks of gestation (control group - CG with n=25 and PE with n=14), we assessed podocyturia (cytospin method) and proteinuria (albuminuria, urine protein:creatinine - PCR, urinary retinol protein - RBP and albumin/creatinine ratio - ACR). (Grant FAPESP 08/56338-1) RESULTS: Mean±standard deviation of age and mean gestational age of CG were 26.9±6.4years and 37.1±5.0weeks and of PE, 26.4±6.9 and 30.6±5.6, respectively (p=0.001). No statistical differences were found between podocyturia in CG and PE although it was more frequent in this last group (p=0.258). Podocyte cells and parietal epithelial cells were detected in the slides. Mean±standard deviation of urinary RBP (p=0.017), albuminuria (p=0.002) and UAC ratio (p=0.006) of CG were 0.4±0.7mg/L, 7.3±6.9mg/L and 8.2±6.7mg/g and of PE, 2.0±4.4mg/L, 2267.4±2130.8mg/L (p=0.002) and 3778.9±4296.6mg/g (p=0.006), respectively. Mean value±standard deviation of urine PCR in PE was 6.7±6.1g/g (p=< 0.001). CONCLUSION: Urinary RBP, PCR, albuminuria and UAC ratio were elevated in PE in comparison to CG indicating its glomerular involvement but there was no correlation between those renal parameters and podocyturia. RPC and UAC ratios were good predictors of PE, but not podocyturia. Either podocyte cells as parietal epithelial cells were detected in the urine, these findings may indicate a non-invasive marker for renal disease activity but more studies are required to determine its role in PE.

PP090. The contribution of podocyturia to the evaluation of ongoing glomerular disorder in pregnant women with kidney graft (preliminary results).

INTRODUCTION: Progressive proteinuria and glomerulosclerosis characterize chronic allograft nephropathy. However, the causes are not fully elucidated. Injury of parietal epithelial cells in glomeruli, the podocytes, is the initiating cause of many renal diseases, leading to proteinuria with possible progression to glomerulosclerosis. Podocytes are highly specialized cells, with an important role in maintaining the glomerular filtration barrier and producing growth factor for mesangial cells and endothelial cells. With their foot processes they cover the glomerular basement membrane, and form slit diaphragms with neighboring podocytes. The potential role of podocytes in the failing transplanted kidney is unknown. OBJECTIVES: To evaluate podocyturia as a functional marker in pregnant women with kidney grafts. METHODS: Twenty pregnant women with kidney grafts had their urine samples cytocentrifugated and evaluated by indirect immunofluorescence. The slide was incubated for 45' at room temperature with fluorescein (FITC) anti-rabbit IgG secondary antibody (Sigma-Aldrich, EUA). Then Vectashield (mounting medium for fluorescence) with DAPI (4'6-diamino-2-fenilindol dihidrocloreto) were applied H-1200 (Vector laboratories, inc, USA). The podocytes and the total number of cells were counted in 15 fields photographed under 400x magnification with a digital camera coupled to an epifluorescence microscope DM1000 (Leica, Germany) connected to a computer. The results were expressed as podocyte/total cells (%) per area of higher cell concentration (hot spots) in the field of 400x detected by staining of nuclei and cytoplasm. (Grant FAPESP 08/56338-1). RESULTS: The mean age of the women was 26years. The urinalysis was performed at the third trimester of gestation; 11 did not exhibit urinary podocytes and 9 had podocyturia. There was also a relationship between blood pressure levels, proteinuria and the excretion of podocytes. CONCLUSION: Urinary podocyte number, blood pressure and proteinuria were associated. We observed that urinary podocyte excretion occurs in pregnant women with kidney transplant almost synchronously with higher systolic and diastolic blood pressure and higher mean levels of proteinuria. The detection of podocyturia in these women could be useful for early diagnosis and follow-up of glomerular injury, eventually preeclampsia. It may be also associated to its severity or activity, although additional studies are necessary to confirm these aspects.

Lung inflammation is induced by renal ischemia and reperfusion injury as part of the systemic inflammatory syndrome.

INTRODUCTION: Ischemia and reperfusion injury (IRI) are mainly caused by leukocyte activation, endothelial dysfunction and production of reactive oxygen species. Moreover, IRI can lead to a systemic response affecting distant organs, such as the lungs. AIM: The objective was to study the pulmonary inflammatory systemic response after renal IRI. METHODS: Male C57Bl/6 mice were subjected to 45 min of bilateral renal ischemia, followed by 4, 6, 12, 24 and 48 h of reperfusion. Blood was collected to measure serum creatinine and cytokine concentrations. Bronchoalveolar lavage fluid (BALF) was collected to determine the number of cells and PGE(2) concentration. Expressions of iNOS and COX-2 in lung were determined by Western blot. Gene analyses were quantified by real time PCR. RESULTS: Serum creatinine increased in the IRI group compared to sham mainly at 24 h after IRI (2.57 +/- 0.16 vs. 0.43 +/- 0.07, p < 0.01). The total number of cells in BAL fluid was higher in the IRI group in comparison with sham, 12 h (100 x 10(4) +/- 15.63 vs. 18.1 x 10(4) +/- 10.5, p < 0.05) 24 h (124 x 10(4) +/- 8.94 vs. 23.2 x 10(4) +/- 3.5, p < 0.05) and 48 h (79 x 10(4) +/- 15.72 vs. 22.2 x 10(4) +/- 4.2, p < 0.05), mainly by mononuclear cells and neutrophils. Pulmonary COX-2 and iNOS were up-regulated in the IRI group. TNF-alpha, IL-1beta, MCP-1, KC and IL-6 mRNA expression were up-regulated in kidney and lungs 24 h after renal IRI. ICAM-1 mRNA was up-regulated in lungs 24 h after renal IRI. Serum TNF-alpha, IL-1beta and MCP-1 and BALF PGE(2) concentrations were increased 24 h after renal IRI. CONCLUSION: Renal IRI induces an increase of cellular infiltration, up-regulation of COX-2, iNOS and ICAM-1, enhanced chemokine expression and a Th1 cytokine profile in lung demonstrating that the inflammatory response is indeed systemic, possibly leading to an amplification of renal injury.

Mesenchymal stem cells ameliorate tissue damages triggered by renal ischemia and reperfusion injury.

BACKGROUND: Ischemia and reperfusion injury (I/R) is the major cause of acute renal failure (ARF) with high mortality rates. Because alternative therapies are needed, we investigated the use of stem cell therapy to modulate inflammation in a renal I/R model. METHODS: To study kidney I/R injury, we clamped bilateral pedicles for 60 minutes. Mesenchymal stem cells (MSC), which had been isolated and cultivated in plastic flasks, were administered to mice 6 hours after injury. Real-time polymerase chain reaction was used to quantify interleukin (IL)-4 and IL-1beta mRNAs. Proliferative nuclear cell antigen (PCNA) was used to calculate tubular regeneration. RESULTS: Administration of MSC attenuated renal injury; serum creatinine and plasma urea levels were significantly reduced 24 hours after reperfusion. PCNA immunohistochemistry showed that regeneration occurred faster in renal tissues of animals that received MSC than in tissues of control animals. Analyses of cytokine expression in renal tissue demonstrated a greater level of anti-inflammatory cytokines in MSC-treated animals. CONCLUSION: These results showed an antiinflammatory pattern in MSC-treated animals, demonstrating the potential of MSC to modulate I/R, leading to earlier regeneration of damaged renal tissue.

A role for HO-1 in renal function impairment in animals subjected to ischemic and reperfusion injury and treated with immunosuppressive drugs.

INTRODUCTION: Ischemia/reperfusion injury (IRI) represents the single major antigen-independent factor implicated in pathogenesis of chronic graft dysfunction. Tacrolimus is a calcineurin inhibitor, which has been suggested to be helpful in cyclosporine-related chronic toxicity. Rapamycin has antiproliferative properties that may impair renal regeneration after IRI. Therefore, immunosuppressive drugs might impair renal graft outcome in those organs suffering IRI. MATERIAL AND METHODS: C57B1/6 male mice subjected to 45 minutes of renal pedicle ligation were reperfused for 24 hours. Mice were treated with rapamycin, cyclosporine, or tacrolimus. Blood and renal tissue samples were collected at 24 hours after IRI. Urea levels were measured. Heme Oxygenase 1 (HO-1) gene transcript was amplified by a real-time polymerase chain reaction technique. RESULTS: Animals treated with cyclosporine and subjected to IRI showed impaired renal function that peaked at 24 hours. Additional pretreatment with rapamycin produced even more impairment of renal function, when compared with controls. However, tacrolimus pretreatment was associated with a better renal outcome. HO-1 expression was upregulated after IRI by 2.6 arbitrary units at 24 hours. Rapamycin showed worse impairment of renal function. CONCLUSION: Tacrolimus was not associated with worsening renal function when compared with animals just subjected to IRI. Upregulation of HO-1 may be an attractive approach to limit graft injury.

The effects of rapamycin in the progression of renal fibrosis.

UNLABELLED: Renal fibrosis is a hallmark of end-stage renal diseases and of chronic allograft nephropathy (CAN). Rapamycin, besides its action through blockade of lymphocyte proliferation, also has antiproliferative, antiviral, and antitumor actions. Its use in clinical in patients with CAN has recently been advocated. OBJECTIVES: Our goal was to evaluate the effect of rapamycin in an established model of renal fibrosis, unilateral ureteral obstruction. MATERIALS AND METHODS: C57BL/6 mice were divided into two groups, treated or not with daily doses of rapamycin (0.2 mg/kg) beginning on day-1. The obstruction was performed as day 0. Blood and kidney tissues were collected at 1, 4, 7, and 14 days after the surgery to quantify bone morphogenic protein (BMP)-7 and transforming growth factor (TGF)-beta mRNA by real time PCR. RESULTS: Daily treatment with rapamycin caused a significant reduction in serum creatinine at day 1 (0.57 +/- 0.03 vs 0.95 +/- 0.15 mg/dL, P = .002) and at day 14 (0.56 +/- 0.04 vs 0.73 +/- 0.07 mg/dL, P = .040). This profile was corroborated by histological morphometric analyses showing less fibrosis at day 14. However, rapamycin surprisingly induced an upregulation of TGF-beta at day 4 (3.05 +/- 0.46 vs 1.85 +/- 0.41, P = .006) and at day 7 (6.33 +/- 0.55 vs 4.97 +/- 0.38, P = .024) with a reduced expression by day 14 (4.03 +/- 1.07 vs 7.89 +/- 0.83, P < .001). Surprisingly, rapamycin also promoted an increment in BMP-7, completely reversing the ratio of TGF-beta to BMP-7, allowing a more protective phenotype. CONCLUSION: Rapamycin slightly ameliorated the renal dysfunction and, at later time points, induced less fibrosis and less decrease in the TGF-beta to BMP-7 ratio.

The role of heme oxygenase 1 in rapamycin-induced renal dysfunction after ischemia and reperfusion injury.

Ischemia and reperfusion injury (IRI) is the main etiology of acute renal failure in native and transplanted kidneys. In the transplantation field, immunosuppressive drugs may play an additional role in acute graft dysfunction. Rapamycin may impair renal regeneration post IRI. Heme oxygenase 1 (HO-1) is a protective gene with anti-inflammatory and anti-apoptotic actions. We investigated whether HO-1 played a role in rapamycin-induced renal dysfunction in an established model of IRI. Rapamycin (3 mg/kg) was administered to mice before being subjected to 45 min of ischemia. Animals subjected to IRI presented with impaired renal function that peaked at 24 h (2.05+/-0.23 mg/dl), decreasing thereafter. Treatment with rapamycin caused even more renal dysfunctions (2.30+/-0.33 mg/dl), sustained up to 120 h after reperfusion (1.54+/-0.4 mg/dl), when compared to the control (0.63+/-0.09 mg/dl, P<0.05). Rapamycin delayed tubular regeneration that was normally higher in the control group at day 5 (68.53+/-2.30 vs 43.63+/-3.11%, P<0.05). HO-1 was markedly upregulated after IRI and its expression was even enhanced by rapamycin (1.32-fold). However, prior induction of HO-1 by cobalt protoporphyrin improved the renal dysfunction imposed by rapamycin, mostly at later time points. These results demonstrated that rapamycin used in ischemic-injured organs could also negatively affect post-transplantation recovery. Modulation of HO-1 expression may represent a feasible approach to limit rapamycin acute toxicity.

Early nuclear alterations and immunohistochemical expression of Ki-67, Erb-B2, vascular endothelial growth factor (VEGF), transforming growth factor (TGF-beta1) and integrine-linked kinase (ILK) two days after tamoxifen in breast carcinoma.

The purpose of the present study was to evaluate breast carcinoma samples before and two days after treatment with tamoxifen in order to analyse early histopathological alterations--particularlynuclear alterations-- as well as immunohistochemical expression of Ki-67, Erb-B2, VEGF, TGF-beta1 and ILK proteins. Twenty one cases of invasive ductal and lobular breast carcinoma were studied. Patients were submitted to biopsy of the lesion and, after confirmation of the diagnosis, they received 20 mg of tamoxifen a day, beginning two days before surgery. The samples obtained during biopsy and after surgery were stained with HE for histopathological diagnosis. Estrogen receptor was positive in 18 cases and negative in 3. The immunohistochemical method was applied for the detection of Ki-67, Erb-B2, protein, vascular endothelial growth factor (VEGF), transforming growth factor beta (TGF-beta1) and integrin linked kinase (ILK). Two days after tamoxifen treatment, the following results were observed: 1) decrease in the cell volume, chomatine condensation, nucleoli less evident and clearly defined nuclear limits; 2) significant reduction in the expression of Erb-B2 protein and significant increase in the expression of TGF-beta1 protein; 3) expression of others proteins (Ki-67, VEGF and ILK) was not altered during the indicated time frame. Our results suggest that analyzing nuclear alterations and expression of Erb-B2 and TGF-beta1 proteins would be useful to assess the initial response to tamoxifen.

Widespread hematogenous metastases and Trousseau's syndrome in gastric adenocarcinoma.

A case of widespread hematogenous metastases and Trousseau's syndrome is reported in a 40 year-old white housewife with gastric cancer, presenting subdural hematoma, ecchymoses, epistaxis, stomach and uterine bleeding. After undergoing hematoma drainage, she was unsuccessfully treated with platelets, red blood cells, plasma cryoprecipitate transfusions, and antibiotics. Necropsy disclosed gastric ring-signet adenocarcinoma invading the serous layer, with massive disseminated intravascular coagulation and systemic neoplastic embolism. Multiple old and recent hyaline (rich in fibrin and platelets) microthrombi, and tumor emboli were observed in the bone marrow, meninges, liver, lungs, kidneys, lymph nodes, adrenals, thyroid, heart, pancreas, and ovaries (Krukenberg tumor).

Altering glomerular epithelial function in vitro using transient and stable transfection.

Damage of the glomerular filtration barrier leads to proteinuria and progressive renal failure. Several independent lines of research have implicated the glomerular epithelial cell (GEC) as a key player in initiation and propagation of pathways leading to glomerulosclerosis. A growing number of molecules activated in this process have been identified. To further define their cellular function, manipulation of these molecules using pharmacological or genetic approaches in tissue culture systems are required. In this study, strategies for altering GEC gene expression by transient and stable transfection of fluorescence labeled proteins will be presented and discussed. The insight gained through these and comparable systems should allow a detailed dissection of the molecular pathways active in GEC function and failure.

Neuron count reevaluation in the myenteric plexus of chagasic megacolon after morphometric neuron analysis.

This study was made with the objective of reevaluating the colon denervation in chronic Chagas' disease. The diameters of neuron perikaryons of the myenteric plexus were measured on paraffin sections in a ring from the sigmoid in Chagas' disease patients, 17 with and 10 without megacolon and in 10 non-chagasic controls. All neurons were counted in ten en-echelon sections. Neuron hypertrophy only occurred in the group with megacolon, and the average increase in diameter was 69.3%. This could generate an error factor in the neuron count by increasing the probability of neurons being seen in a greater number of histological sections. The original result of the neuron count gave medians of 1264, 1961, and 2665 in the groups of chagasic patients with megacolon, without megacolon, and in the control, respectively. The denervation was greater than 55% in only seven megacolon cases (41.2%). After applying a correction factor, the median in the group with megacolon was 746, and the denervation was greater than 55% in 13 cases (76.5%). This occurrence demonstrates the need to apply a correction factor when the neuron count in chagasic megacolon is being evaluated and in the other pathologies where neuron hypertrophy may be found.

Effects of ionizing radiation on progressive experimental renal disease: a hemodynamic approach.

In order to evaluate the progression of renal disease, Munich-Wistar rats were submitted to 5/6 nephrectomy and given whole-body x- or gamma-irradiation with or without remnant kidney protection or were submitted only to remnant kidney irradiation. All groups received a single 6-Gy dose immediately after surgery. Whole-kidney function, glomerular hemodynamics, 24-hour proteinuria and histopathology were assessed 60 days after surgery and irradiation. The irradiated nephrectomized animals presented whole-kidney function parameters comparable to those of normal rats. In addition, they were less hypertensive and had higher hematocrit. They showed glomerular hyperfiltration and hypertension even greater than their respective nephrectomized controls. However, the interrelations among the glomerular filtration determinants were somewhat different in irradiated animals. Their 24-hour proteinuria was significantly lower and the sclerosis index and tubulointerstitial injury score were markedly smaller. Among irradiated animals, the worst sclerosis index was observed in those with a shielded remnant kidney and the best in those without protection of the remnant kidney. This led us to speculate about a possible influence of resident mesangial cells on the early events following renal mass ablation and on the maintenance of subsequent physiopathologic changes. Therefore, radiation undoubtedly provoked a beneficial change in the course of renal disease when the renal mass ablation model was employed. Many factors could have contributed to this favorable feature including lower levels of systemic arterial pressure, less increment in DeltaP, diminished proteinuria, and maintenance of tubulointerstitial space integrity. Our data also suggest that development of glomerulosclerosis seems to be determined by events occurring immediately after injury.

Morphologic and morphometric evaluation of pancreatic islets in chronic Chagas' disease.

PURPOSE: Hyperglycemia and abnormal glucose tolerance tests observed in some patients with chronic Chagas' disease suggest the possibility of morphological changes in pancreatic islets and/or denervation. The purpose of this study was to describe the morphology and morphometry of pancreatic islets in chronic Chagas' disease. METHODS: Morphologic and computerized morphometric studies were performed in fragments of the head, body, and tail regions of the pancreas obtained at necropsies of 8 normal controls and 17 patients with chronic Chagas' disease: 8 with the digestive form (Megas) and 9 with the congestive heart failure form. RESULTS: The Megas group had a larger (p < 0.05) pancreatic islet area in the tail of the pancreas (10649.3 +/- 4408.8 micrometer2) than the normal control (9481.8 +/- 3242.4 micrometer2) and congestive heart failure (9475.1 +/- 2104.9 micrometer2) groups; likewise, the density of the pancreatic islets (PI) was greater (1.2 +/- 0.7 vs. 0.9 +/- 0.6 vs. 1.9 +/- 1.0 PI/mm2, respectively). In the tail region of the pancreas of patients with the Megas form, there was a significant and positive correlation (r = +0.73) between the area and density of pancreatic islets. Discrete fibrosis and leukocytic infiltrates were found in pancreatic ganglia and pancreatic islets of the patients with Chagas' disease. Trypanosoma cruzi nests were not observed in the examined sections. Individuals with the Megas form of Chagas' disease showed increased area and density of pancreatic islets in the tail of the pancreas. CONCLUSION: The observed morphometric and morphologic alterations are consistent with functional changes in the pancreas, including glycemia and insulin disturbances.

[Contribution to the morphologic diagnosis of lung adiaspiromycosis]. / Contribuição ao diagnóstico morfológico da adiaspiromicose pulmonar.

The diagnosis of adiaspiromycosis is usually based on lung sections stained by hematoxylin-eosin, periodic acid Schiff and methenamine silver. Authors describe the fungus aspect examined by mucicarmin, picro-sirius and Congo red methods, including polarized light microscopy. In doubtful cases, these methods could contribute to histopathological diagnosis of Emmonsia parva var crescens.

Pressure sores among malnourished necropsied adults--preliminary data.

UNLABELLED: Pressure sores are common among bedridden, elderly, or malnourished patients, and may occur in terminal ill patients because of impaired mobility, fecal or urinary incontinence, and decreased healing capacity. The aim of this study was to compare frequency of pressure sores between malnourished and non-malnourished necropsied adults. METHOD: All (n = 201) adults (age >/= 18 years) autopsied between 1986 and 1996 at the Teaching Hospital of Triangulo Mineiro Medical School (Uberaba) were eligible for the study. Gender, race, weight, height and main diagnoses were recorded. Ninety-six cases were excluded because of probable body water retention (congestive heart failure, hepatic insufficiency, nephrotic syndrome) or pressure sores secondary to peripheral vascular ischemia. Body mass index (BMI) was used to define malnourished (BMI < 18.5 kg/m2) and non-malnourished (BMI > 18.5kg/m2) groups. RESULTS: Except for weight (42.5kg; range: 28-57 vs. 60; 36-134.5kg) and BMI (16.9; range: 12.4-18.5 vs. 22.7; range: 18.5-54.6kg/m2), respectively, there were no statistical differences among 43 malnourished and 62 non-malnourished cases in relation to age (54.9 +/- 20.4 vs. 52.9 +/- 17.9 years), percentage of white persons (74.4 vs. 64.5%), male gender (76.7 vs. 69.3%) and main diagnoses. Five malnourished (11. 6%) and 7 (11.5%) non-malnourished cases had pressure sores (p=0.89). CONCLUSION: Pressure sores were equally common findings in necropsied persons with protein-energy malnutrition, as assessed by body mass index.
