RESUMO

BACKGROUND: Contaminated blenderised tube feeding (BTF) causes numerous infections in patients with deficient immune systems. The microbial quality of BTF should be thoroughly monitored to reduce the risks of microbial agents and prevent food safety problems such as food poisoning and food-borne illnesses. The aim of this study was to survey the contamination rate of BTF samples prepared in the teaching hospitals in Mashhad, Iran. METHODS: This study was conducted on 24 samples of BTF prepared in four teaching hospitals in Mashhad city; the samples were collected randomly. Then specific culture media were used for detected and counted Listeria monocytogenes, Salmonella spp., Staphylococcus aureus, Clostridium perfringens, Bacillus cereus, coliforms and Escherichia coli. The final confirmation of the isolates was performed using polymerase chain reaction. RESULTS: The total bacterial count was determined in the BTF samples and compared with the Food and Drug Administration medical food standards; 91.6% of the samples had 5.2 ± 0.1 log CFU/ml microbial bacterial contamination considering the standard range. The mean prevalence of contamination in these samples was measured for coliforms 4.9 ± 0.17 log CFU/ml, B. cereus 3.6 ± 0.16 log CFU/ml, S. aureus 3.7 ± 0.15 log CFU/ml and C. perfringens 4.7 ± 0.08 log CFU/ml (p < 0.05). Moreover, E. coli 11 (45.8%), Salmonella spp. 9 (37.5%) and L. monocytogenes 17 (70.8%) samples were detected. CONCLUSION: Given the high consumption of BTF and the transmission of food contamination to hospitalised patients, it is essential to improve the hygienic conditions at the site of BTF preparation to prevent re-contamination.

RESUMO

This study aimed to investigate the prevalence of Methicillin- and Vancomycin-Resistant Staphylococcus aureus (MRSA, VRSA) and Vancomycin-Resistant Enterococcus (VRE) of hospital food samples in Mashhad, Iran. A total of 357 hospital food samples were collected from 13 hospitals. Enterococcus spp. and Staphylococcus aureus were identified using conventional cultural techniques following genotypic confirmation by PCR. The antibiotic resistance patterns of MRSA, VRSA, and VRE strains were analyzed using the disk diffusion methods. The prevalence of S. aureus and MRSA were 24.37% (87/357) and 22.98% (20.87), respectively. In addition, the vanB gene involved in vancomycin resistance was detected in 1.14% of the S. aureus strains. Enterococci and VRE had a prevalence of 15.4% (55/357) and 21.81% (12/55), respectively. Meat, chicken barbecues, and salad were the most commonly contaminated samples with S. aureus, MRSA, Enterococci, and VRE. PCR detected two vancomycin resistance genes, including vanA (1.81%, 1.55) and vanC2 (20%, 11.55) genes. MRSA strains revealed the highest resistance against penicillin, erythromycin, clindamycin, azithromycin, tetracycline, and gentamicin. The VRSA isolates were resistant to penicillin, ampicillin, oxacillin, cefoxitin, clindamycin, erythromycin, gentamicin, and trimethoprim-sulfamethoxazole. Furthermore, VRE isolates exhibited the highest resistance against quinupristin-dalfopristin, erythromycin, and tetracycline. The results of this study indicated that hospital foods might act as a reservoir of Enterococci spp. and S. aureus strains, which can transfer antibiotic resistance. Moreover, multidrug resistance (MDR) in some MRSA, VRSA, and VRE isolates represents a serious threat to susceptible persons in hospitals.

RESUMO

INTRODUCTION: Protein-energy wasting (PEW) is common in hemodialysis patients and is linked with a high rate of morbidity and mortality. Regarding importance of nutrition in these patients, a recent study was administered to evaluate the nutritional status of hemodialysis patients. MATERIALS: In this cross-sectional study 540 HD patients from 15 dialysis centers were evaluated. The nutritional status of the patients was determined by Subjective Global Assessment (SGA), Dialysis Malnutrition Score (DMS), and Malnutrition Inflammation Score (MIS). Their dietary intakes were assessed using a Food Frequency Questionnaire (FFQ). RESULT: Based on DMS, 66.7% of HD patients were well nourished and the prevalence of mild-to-moderate and severe PEW were 32.4% and 0.9% in HD patients, respectively. Based on MIS, 65.2% of HD patients were well nourished and the prevalence of mild-to-moderate and severe PEW was 34.0%. The prevalence of mild-to-moderate and severe malnutrition based on SGA was 35.0% and 1.1%, respectively. Energy and protein intake in 85.6% and 80.6% of patients respectively were less than the minimum recommended amount. CONCLUSION: HD patients are at risk of malnutrition and in this regard training the patient, periodic assessment of nutritional status, and referring them to a dietitian seems necessary.

RESUMO

BACKGROUND AND AIMS: There is some promising evidence regarding the beneficial effect of coconut oil on cardiometabolic risk factors. This study aimed to assess the effects of virgin coconut oil (VCO) consumption on metabolic syndrome (MetS) components, as well as, asymmetric dimethylarginine (ADMA) in adults with MetS. METHODS AND RESULTS: In this randomized controlled trial, 48 subjects, aged 20-50 years, with MetS were allocated into two groups; the intervention group was given 30 ml of VCO per day to substitute the same amounts of fat in their usual diet for four weeks. The control group was advised to follow their usual diet. VCO consumption significantly reduced serum levels of triglyceride (TG) (P = 0.001), very low-density lipoprotein (VLDL) (P = 0.001), and fasting blood sugar (FBS) (P = 0.015) compared to the control group. The levels of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) were significantly increased in the VCO group when compared to the control group (P = 0.001). Circulatory ADMA also increased in the VCO group compared to the control group (P = 0.003). No significant differences were observed in the LDL-C/HDL-C ratio, anthropometric parameters, and blood pressure measurements between the two groups at the end of the study (P > 0.05). CONCLUSION: VCO consumption increased the values of HDL-C while reduced TG and FBS levels. Blood pressure and waist circumference did not change. However, levels of TC, LDL-C, and ADMA elevated by VCO consumption. Caution is warranted until the results of further studies become available to explain the long-term effects of VCO consumption.

RESUMO

BACKGROUND: Disease-related malnutrition is associated with adverse outcomes such as increased rates of morbidity and mortality, prolonged hospital stay, and extra costs of health care. This study was conducted to assess nutritional status among patients and to determine the risk factors for malnutrition in Iran university f. METHODS: Persian Nutritional Survey In Hospitals (PNSI) was a cross-sectional study that conducted in 20 university hospitals across Iran. All the patients with age range of 18 to 65 years, who were admitted or discharged, were assessed by subjective global assessment (SGA). RESULTS: In total, 2109 patients were evaluated for malnutrition. Mean values of age and body mass index were 44.68 ± 14.65 years and 25.44 ± 6.25 kg/m2, respectively. Malnutrition (SGA-B & C) was identified in 23.92% of the patients, 26.23 and 21% of whom were among the admitted and discharged patients, respectively. The highest prevalence of malnutrition was in burns (77.70%) and heart surgery (57.84%) patients. Multivariate analysis presented male gender (OR = 1.02, P < 0.00), malignant disease (OR = 1.40, P < 0.00), length of hospital stay (OR = 1.20, P < 0.00), and polypharmacy (OR = 1.06, P < 0.00) as independent risk factors for malnutrition. Malnutrition was not associated with age (P = 0.10). CONCLUSION: This study provides an overall and comprehensive illustration of hospital malnutrition in Iran university hospitals, finding that one out of four patients were malnourished; thus, appropriate consideration and measures should be taken to this issue.

RESUMO

BACKGROUND: Arterial stiffness (AS) indicates the initial stage of cardiovascular disease (CVD), which is associated with modifiable and lifestyle risk factors. We aimed to examine the association of AS with anthropometric indices, lipid profiles and physical activity (PA). METHODS: Six hundred and fifty-eight healthy middle-aged adults were selected and anthropometric indices [body mass index, waist circumferences (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), neck circumferences, a body shape index (ABSI), body roundness index (BRI), body fat mass (BFM), visceral fat area, fat-free mass (FFM), lipid profiles and PA] were measured. AS is measured by carotid-femoral pulse wave velocity (cf-PWV) and central augmentation index (cAIx). RESULTS: Our results show that cf-PWV was positively associated with TGs (ß = 0.10, P = .01) and anthropometric indices correlated with WC (ß = 0.11, P = .02), WHR (ß = 0.09, P = .03), WHtR (ß = 0.1, P = .02) and BRI (ß = 0.09, P = .04). cAIx was independently positively associated with cholesterol (ß = 0.08, P = .03), WC (ß = 0.1, P = .03), WHR (ß = 0.09, P = .02), ABSI (ß = 0.09, P = .01), BRI (ß = 0.08, P = .05), visceral fat area (ß = 0.09, P = .03) and BFM (ß = 0.08, P = .04) and negatively associated with PA (ß = -0.08, P = .03). CONCLUSIONS: WC, WHR and BRI were associated with both cf-PWV and cAIx. TGs and WHtR were associated with cf-PWV, while cAIx was associated with ABSI, improving these indices may be helpful to prevent CVD.

RESUMO

Cardiovascular disease is a leading cause of death in many societies. Arterial stiffness is an initial sign of structural and functional changes in the arterial wall. Pulse wave velocity (PWV) is the gold standard for non-invasive evaluation of aortic stiffness and a modifiable cardiovascular risk factor. Curcumin is a major component of turmeric with known anti-inflammatory and anti-oxidative effects. Since arterial stiffness is affected by inflammation and oxidative stress, it may be improved by curcumin supplementation. The purpose of this clinical trial was to investigate the potential effects of curcumin on improving arterial stiffness in patients with metabolic syndrome. This placebo-controlled, double-blind, randomized clinical trial was conducted among metabolic syndrome patients. Sixty-six eligible individuals were randomly assigned to active intervention or control groups. The active intervention group received curcumin supplement at a dose of 500 mg daily for 12 weeks, whereas the control group received placebo capsule. Physical activity, daily dietary energy intake, anthropometric body composition, and biochemical hemodynamic and arterial stiffness parameters were evaluated at baseline and at the end of the study. Body weight decreased significantly in the curcumin group compared to placebo. Also, curcumin intervention improved PWV, which remained significant after adjustment for potential confounding factors (p = 0.011). The current clinical trial demonstrated that daily intake of 500 mg of curcumin for 12 weeks can lead to the improvement of arterial stiffness and weight management among subjects with metabolic syndrome.

RESUMO

Inflammation plays an important role in the pathophysiology of traumatic brain injury (TBI). Based on the anti-inflammatory properties of French maritime pine bark extract and the neuroprotective effects, we aimed to evaluate the effects of its supplementation on TBI. Sixty-seven TBI patients admitted to the intensive care units (ICUs) were enrolled. After stabilizing the hemodynamic status, the intervention group received 150 mg of French maritime pine bark extract supplementation (Oligopin) with enteral nutrition for 10 days. The control group received a placebo. Inflammatory status and oxidative stress markers were measured three times. Also, clinical and nutritional statuses were assessed. Supplementation, significantly decreased IL-6 (ß = -53.43 pg/ml, 95% confidence interval [CI] = -91.74, -15.13, p = .006), IL-1ß (ß = -111.66 pg/ml, 95% CI = -183.79, -39.5402, p = .002) and C-reactive protein (ß = -19.99 mg/L, 95% CI = -27.23, -12.76, p Ëƒ .001) in the intervention group compared to control group after 10 days. Clinical scores including acute physiology and chronic health evaluation II and sequential organ failure assessment were reduced (ß = -3.72, 95% CI = -5.96, -1.49, p = .001and ß = -2.07, 95% CI = -3.23, -0.90, p < .001, respectively), and Nutric score was reduced compared to control group (ß = -.60, 95% CI = -1.08, -0.12, p = .01). The survival rate was higher by 15% in the intervention group compared to control group. Oligopin supplementation in TBI patients in ICU reduced inflammation and improved the clinical status and malnutrition score and thereby reducing the mortality rate.

RESUMO

Experimental studies have suggested the beneficial effects of curcuminoids as natural polyphenols against traumatic brain injury (TBI). The aim of this study was to investigate the effects of supplementation with curcuminoids on inflammatory and oxidative stress biomarkers, clinical outcomes and nutritional status in critically ill patients with TBI. A total of 62 ICU-admitted adult patients with TBI were randomly allocated to receive either a daily dose of 500 mg curcuminoids or matched placebo via enteral nutrition for 7 consecutive days based on stratified block randomization by age and sex. Inflammatory and oxidative stress as well as clinical outcomes and nutritional status of the patients were measured at baseline and at the end of the study. There were no overall group effects regarding to all dependent variables. Compared with baseline, serum levels of IL-6, TNF-α, MCP-1 and CRP were significantly reduced in patients receiving curcuminoids (p < .05) without any significant changes in placebo group; however, changes in the activities of GPx and SOD in serum were not significant between two groups. Moreover, APACHEII and NUTRIC score were significantly improved following curcuminoids consumption in comparison with placebo (p < .05). The findings of this study suggest that short-term supplementation with curcuminoids may have beneficial effects on inflammation, clinical outcomes and nutritional status of critically ill patients with TBI.

RESUMO

BACKGROUND: Food frequency questionnaires (FFQs) are inexpensive, easy to administer, and practical tools for dietary assessment in epidemiological studies. Several studies have investigated the validity and reproducibility of FFQs for the Iranian population. This systematic review aimed to assess the developed and validated FFQs for use in the Iranian population and compare their features and the validation studies in this regard. MATERIALS AND METHODS: A comprehensive search was conducted in ISI Web of Knowledge, PubMed, Scopus, and Iranian databases without time constraints to retrieve the relevant English and non-English publications. Studies would be included if they were focused on the design and validation of FFQs in Iran. RESULTS: In total, 782 articles were found, 22 of which met the eligibility criteria and evaluated 18 FFQs. Validation studies had been conducted on 18 out of 20 FFQs. The median of the correlation coefficients for the comparison of the FFQ intakes and the dietary reference method by nutrients varied within the range of 0.19-0.65, indicating reasonable validity. The median of the correlation coefficients for the comparison of two FFQs by nutrients was 0.28-0.85, showing appropriate reproducibility. However, low validity was observed in some nutrients and food groups, such as egg, legumes, iron, folate, and α-tocopherol. In seven studies, biomarkers were used for the assessment of nutrient intake using an FFQ with the median correlation coefficient of -0.07-0.42. In addition, the quality of methodology was evaluated in the FFQ validation studies, with 18 out of 20 studies reporting good and excellent quality. CONCLUSION: Although the FFQs used to assess the dietary intake of the Iranian population have different features, they have acceptable validity and reproducibility. Nevertheless, some food groups and nutrients have poor validity and must be considered attentively.

RESUMO

Oxidative stress is an important factor in the etiology of several chronic diseases that include cardiovascular disease (CVD), Type 2 diabetes (T2D), and rheumatoid arthritis (RA). Oxidative stress can lead to inflammation, and this can contribute to these chronic diseases. Reducing inflammation and oxidative stress may, therefore, be useful in the prevention and treatment of these conditions. One of the treatment options for chronic diseases is the use of traditional medicine and herbs, such as Nigella sativa. This is one of the herbs that have recently been assessed for its ability to reduce inflammation and oxidative stress. We have reviewed the reported effects of N. sativa on risk factors of chronic diseases (CVD, DM, and RA) with emphasis on molecular and cellular mechanisms in controlling inflammation and oxidative stress. Various mechanisms have been proposed to contribute to the beneficial properties of N. sativa, including a reduction of lipid peroxidation via its antioxidant properties; agonist of peroxisome proliferator-activated receptor gamma in adipose tissue; activation of AMP-activated protein kinase, increased antioxidants, inhibition of nuclear factor-kappa B pathway; increased in interleukin-10 expression, CD4+ T-cell percentage, T regulatory cell percentage (CD4+ CD25+ T-cell) in peripheral blood, and CD4+/CD8+ ratio, but to prove this claim, it is necessary to conduct experimental and well-designed clinical trial studies with a larger sample size on the effects of N. sativa on these chronic diseases.

RESUMO

AIMS: The purpose of this review was to investigate the effect of vitamin D supplements on hemoglobin concentration in subjects aged 17.5-68 years old; using randomized controlled trials (RCTs). METHODS: Relevant RCT studies were identified from January 2000 to January 2019 by using MeSH terms in PubMed, Embase, Cochrane Library, Clinical trials, Scopus databases and gray literature. The studies were reviewed systematically, and quality assessments were evaluated by the guidelines of the Cochrane risk of bias. The effect of vitamin D supplements (n = 14) on hemoglobin concentration was considered as primary outcome, while its effects on the levels of ferritin, transferrin saturation and iron status were derived as secondary outcomes. In total, 1385 subjects with age range of 17.5 to 68 years old were examined for 3 h to 6 months; Mean (standard deviation) or median interquartile changes in the hemoglobin concentration in each treatment group was recorded for meta-analysis. RESULTS: Fourteen RCTs met the inclusion criteria. Current study findings propose that vitamin D supplementation leads to a non-significant reduction in hemoglobin levels in subjects (17.5-68 years old) [std. mean difference (SMD): 0.01; 95% CI: - 0.28, 0.29; P = 0.95], also it has no significant effect on ferritin concentrations [std. mean difference (SMD): -0.01; 95% CI: [- 0.20, 0.18; P = 0.91]. However, vitamin D supplementation demonstrated positive effects on transferrin saturation [mean difference (MD): 1.54; 95% CI: 0.31, 2.76; P = 0.01] and iron status [std. mean difference (SMD): 0.24; 95% CI: - 0.09, 0.39; P = 0.002]. CONCLUSION: Current review concluded that supplementation with vitamin D had no significant effect on hemoglobin and ferritin levels while positive effects on transferrin saturation and iron status were observed. Further clinical studies are required to determine the actual effect of this intervention on hemoglobin levels.

RESUMO

Previous studies have shown a beneficial effect of curcuminoids supplementation on serum concentrations of adipokines; however, there are no published studies that have examined this effect among critically ill patients. We aimed to assess the effects of supplementation with curcuminoids on serum concentrations of leptin and adiponectin in critically ill patients with traumatic brain injury (TBI). In this trial, 62 critically ill patients with TBI, aged 18-65 years, were randomly allocated to receive either 500 mg/day curcuminoids (co-administered with 5 mg/day piperine) or matched placebo for 7 days. Patients in both intervention groups received routine treatments for TBI as well as enteral nutrition. Serum concentrations of leptin and adiponectin were measured at baseline and at the end of trial. We found a significant reduction in serum levels of leptin in both curcuminoids (47.1%) and placebo (22.8%) groups; though the magnitude of reduction was greater in the former (p < .05). Supplementation with curcumioinds was not found to alter serum concentrations of adiponectin (p > .05). Supplementation with curcumioinds significantly reduced serum levels of leptin but had no significant effect on adiponectin levels in critically ill patients with TBI. Further clinical trials, particularly those with a long-term period, are needed to confirm our findings.

RESUMO

BACKGROUNDS: To assess the validity and reliability of the Persian version of Nutrition Screening Tool for Every Preschooler (NutriSTEP®), a community-based nutrition screening tool in preschool children. DESIGN AND METHODS: A cross-cultural validation study was conducted on 192 Iranian preschool children in Mashhad, Iran. Forward and backward translation and face validity was assessed. Criterion validity was confirmed by nutritionist risk score which was determined by an expert physician. Content validity, construct validity and reliability of the Persian version was assessed as well. Receiver operating characteristic (ROC) curve was used to detect the reasonable cut-points for the Persian version. FINDINGS: Content validity index and ratio ranged between 0.9 and 1 and 0.63-1, which both were acceptable. NutriSTEP® scores were significantly different in the three categories of nutritionist risk scores (p = .007). Item-to-scale correlation analysis shows significant correlation between each item and the total score. A significant correlation was seen between test-retest scores of NutriSTEP® (r = 0.68, p < .001). In Persian NutriSTEP®, scores 27 and 31 seems to better reflect the nutrition risk in Iranian preschool children population and are suggested as cut-points; Therefore, scores lower or equal to 27 are determined as mild risk and 28-31 as moderate risk, while scores higher than 31 are categorized as high risk. CONCLUSION: The Persian NutriSTEP® questionnaire is both valid and reliable for the screening of nutrition risk in preschool children of the Iranian population. PRACTICE IMPLICATIONS: Health care professionals may use the NutriSTSP® tool to find nutritionally high risk children as an important step to prevent childhood obesity.

RESUMO

AIM: Clinical trials on the effect of pycnogenol supplementation on cardiometabolic health have been controversial. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the potential effect of pycnogenol supplementation on cardiometabolic profile. METHODS: PubMed, Scopus, and ISI Web of Science databases were searched until October 2018. RCTs that evaluated the effects of pycnogenol on cardiometabolic parameters were included. DerSimonian and Laird random-effect models were used to compute the weighted mean differences (WMDs) and 95% confidence intervals (CIs). RESULTS: Twenty-four RCTs including 1594 participants were included in the meta-analysis. Pycnogenol significantly reduced fasting blood glucose (WMD: -5.86 mg/dl; 95% CI: -9.56, -2.15), glycated hemoglobin (WMD = -0.29%, 95%CI: -0.56, -0.01), systolic blood pressure (WMD: -2.54 mmhg; 95% CI: -4.08, -0.99), diastolic blood pressure (WMD: -1.76 mmhg; 95% CI: -3.12, -0.41), body mass index (WMD: -0.47 kg/m2; 95% CI: -0.90, -0.03), LDL cholesterol (WMD: -7.12 mg/dl; 95% CI: -13.66, -0.58) and increased HDL cholesterol (WMD: 3.27 mg/dl; 95% CI: 0.87, 5.66). CONCLUSION: This meta-analysis suggests that pycnogenol may have a role in preventing cardiometabolic disease. However, further well-designed RCTs are recommended to evaluate its long-term effects and explore the optimal duration of use and dosage.

RESUMO

Background and objective: The aim of the present study was to examine the relationship between serum levels of pro-inflammatory cytokines (IL-6, IL-1ß, and TNF-α) and anti-inflammatory cytokines (IL-10) measured once at the baseline with changes in nutritional status of patients with traumatic head injury (THI) assessed at three consecutive times (24 h after admission, day 6 and day 13) during hospital stay in the intensive care unit (ICU). Materials and Methods: Sixty-four patients with THI were recruited for the current study (over 10 months). The nutritional status of the patients was determined within 24 h after admission and on days 6 and 13, using actual body weight, body composition analysis, and anthropometric measurements. The APACHE II score and SOFA score were also assessed within 24 h of admission and on days 6 and 13 of patients staying in the ICU. Circulatory serum levels of cytokines (IL-6, IL-1ß, TNF-α, and IL-10) were assessed once within 24 h of admission. Results: The current study found a significant reduction in BMI, FBM, LBM, MAUAC, and APM, of THI patients with high serum levels the cytokines, over the course of time from the baseline to day 7 and to day 13 in patients staying in the ICU (p < 0.001). It was also found that patients with low levels of some studied cytokines had significant improvement in their nutritional status and clinical outcomes in term of MAUAC, APM, APACHE II score and SOFA score (p < 0.001 to p < 0.01). Conclusion: THI patients who had high serum levels of studied cytokines were more prone to develop a reduction of nutritional status in terms of BMI, FBM, LBM MAUAC and APM over the course of time from patient admission until day 13 of ICU admission.

RESUMO

Very-early-onset inflammatory bowel disease (VEO-IBD) has a distinct phenotype and should be considered a specific entity. VEO-IBD presents with very severe clinical pictures and is frequently known by an indeterminate colitis whose clinical remission is unmanageable. This study examines the case of a neonate with VEO-IBD, not responding to medical and surgical treatment. A 7-day-old Iranian female neonate presented with severe bloody diarrhea, poor feeding, abdominal distention, and dehydration suggesting severe proctocolitis due to an allergy to the protein in cow's milk. The condition did not respond to the elimination of diet for 1 month. Infections, celiac disease, and cystic fibrosis were excluded. Immunological investigations were negative, but antineutrophil cytoplasmic antibodies were positive. Due to the neonate's persistent symptoms and failure to thrive, upper and lower endoscopies were performed, showing ulcerative colitis. At the age of 4 months, she presented with signs and symptoms of toxic colitis and acute intestinal perforation, which prompted an emergency laparotomy. Due to the necrosis of the colon, hemicolectomy and colostomy were done. The patient was resuscitated and rehabilitated and was given glucocorticoid and mesalamine. We believe that the incidence of this problem is increasing, as is shown by the rise in the number of children under 10 years old being diagnosed. These patients require more aggressive therapeutic interventions than older IBD patients to achieve complete remission because they are more likely to have extensive colonic disease.
