ABSTRACT

Cardiovascular diseases are among the main causes of death in Brazil and worldwide. The literature indicates the hypertriglyceridemic waist phenotype (HTWP) as an accessible alternative for the identification of cardiovascular and metabolic risk. The present study aimed to identify the prevalence and factors associated with HTWP in individuals diagnosed with arterial hypertension (AH) and/or diabetes mellitus type 2 (DM2). A cross-sectional study was conducted with individuals diagnosed with AH and/or DM2. The study data were collected through semi-structured interviews containing socio-demographic information, lifestyle, health care, in addition to anthropometric assessment, blood pressure measurement and biochemical blood tests. The prevalence of HTWP was estimated and bivariate and multivariate logistic regression was used to assess the factors associated with HTWP. Of the 788 individuals analysed, 21⋅5 % had the HTWP. In the adjusted model, the following variables remained associated with a greater chance of presenting HTWP: sex, age, body mass index (BMI) and very-low-density lipoprotein (VLDL). Being female increased the chance of HTWP by 7⋅7 times (OR 7⋅7; 95 % CI 3⋅9, 15⋅2). The one-year increase in age increased the chance of HTWP by 4 % (OR 1⋅04; 95 % CI 1⋅02, 1⋅06). The addition of 1 mg/dl of VLDL-c increased the chance of HTWP by 15 % (odds ratio (OR) 1⋅15; 95 % confidence interval (CI) 1⋅12, 1⋅18), as well as the increase of 1 kg/m2 in the BMI increased the chance of this condition by 20 % (OR 1⋅20; 95 % CI 1⋅15, 1⋅27). The prevalence of HTWP was associated with females, older age, higher BMI, higher VLDL-c and risk waist/height ratio.

ABSTRACT

Diabetes mellitus (DM) and arterial hypertension (AH) are the two main clinical conditions related to Chronic Kidney Disease (CKD); disease also identify by the levels of low-grade albuminuria (LGA). Few studies have simultaneously investigated the associations of glycated hemoglobin (HbA1c) and fasting plasma glucose (FPG) with LGA. Our study aimed to investigate and compare the association of HbA1c and FPG with the probability of LGA in adult and elderly individuals with DM and AH, within the scope of Primary Health Care (PHC). Cross-sectional study involving 737 Brazilians individuals previously diagnosed with hypertension and/or diabetes. Tests for HbA1c, FPG and LGA were performed. LGA was defined as the highest quartile of albumin urinary (≥ 13 mg/g) among individuals with urinary LGA < 30 mg / g. A significant increase in the prevalence of LGA was found with increasing levels of HbA1c (p < 0.001). There was a significant association of HbA1c with LGA (p < 0.001) and increased probability of LGA for participants with HbA1c ≥ 6.5% compared to those with Hba1c < 5.7% (OR [95% CI]: 2.43 [1.32-4.46], p < 0.05), after adjusting for confounding factors, except when adjusted for FPG (p = 0.379 and p = 0.359, respectively). HbA1c and FPG were significantly associated in a collinear manner with an increased probability of LGA in adult and elderly individuals with DM and AH.

ABSTRACT

PURPOSE: restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice in some cases of familial adenomatous polyposis (FAP) and ulcerative colitis (UC). IPAA allows complete removal of the diseased colon and rectum, however, it is associated with substantial morbidity and potential consequences to patients' quality of life (QoL). AIMS: to evaluate the surgical results, functional outcomes and QoL after IPAA; and to examine the impact of surgical complications upon QoL. METHODS: we reviewed the records of 55 patients after IPAA, with emphasis on surgical outcomes. Forty patients answered the questionnaires. The Cleveland Global Quality of Life (CGQL), Inflammatory Bowel Disease Questionnaire (IBDQ), and Short Form 36 Health Survey Questionnaire (SF36). RESULTS: the average age was 42.1±14.1 years. 63.6% of the patients were male, and 69.1% had FAP. Operative mortality was 1.8% and overall morbidity was 76.4%. Anastomotic leakage was the most frequent early complication (34.5%). Pouchitis (10.8%) and small bowel obstruction (9.1%) were the most common late complications. Patients with UC had the most severe complications (p=0.014). Pelvic complications did not have a negative effect on functional outcomes or QoL scores. Female patients had decreased pouch evacuation frequency, fewer nocturnal bowel movements, decreased bowel symptom impact on QoL (p=0.012), and better CGQL (p=0.04). Patients with better education had better QoL scores, and patients who had their pouches for more than five years scored lower. CONCLUSION: the high morbidity has no impact on function or QoL. Bowel function is generally acceptable. QoL is good and affected by sex, education and time interval since IPAA.

ABSTRACT

BACKGROUND: optimal management of end-stage renal disease (ESRD) in hemodialysis (HD) patients should be more studied because it is a serious risk factor for mortality, being considered an unquestionable global priority. METHODS: we performed a retrospective cohort study from the Nephrology Service in Brazil evaluating the survival of patients with ESRD in HD during 20 years. Kaplan-Meier method with the Log-Rank and Cox's proportional hazards model explored the association between survival time and demographic factors, quality of treatment and laboratory values. RESULTS: Data from 422 patients were included. The mean survival time was 6.79 ± 0.37. The overall survival rates at first year was 82,3%. The survival time correlated significantly with clinical prognostic factors. Prognostic analyses with the Cox proportional hazards regression model and Kaplan-Meier survival curves further identified that leukocyte count (HR = 2.665, 95% CI: 1.39-5.12), serum iron (HR = 8.396, 95% CI: 2.02-34.96), serum calcium (HR = 4.102, 95% CI: 1.35-12.46) and serum protein (HR = 4.630, 95% CI: 2.07-10.34) as an independent risk factor for the prognosis of survival time, while patients with chronic obstructive pyelonephritis (HR = 0.085, 95% CI: 0.01-0.74), high ferritin values (HR = 0.392, 95% CI: 0.19-0.80), serum phosphorus (HR = 0.290, 95% CI: 0.19-0.61) and serum albumin (HR = 0.230, 95% CI: 0.10-0.54) were less risk to die. CONCLUSION: survival remains low in the early years of ESRD treatment. The present study identified that elevated values of ferritin, serum calcium, phosphorus, albumin, leukocyte, serum protein and serum iron values as a useful prognostic factor for the survival time.

ABSTRACT

The present study aimed to evaluate the prevalence of chronic kidney disease (CKD) in individuals with arterial hypertension (AH) and/or diabetes mellitus (DM) accompanied by Primary Health Care (PHC) in Brazil. The estimated glomerular filtration rate (eGFR) based on creatinine, and urinary albumin-to-creatinine ratio (ACR) were measured in 841 subjects with AH and/or DM, followed by PHC in the city of Viçosa. The CKD was diagnosed according to KDIGO criteria. Sociodemographic, clinical, and anthropometric factors related to the prevalence of CKD were investigated through multiple logistic regression. The prevalence of hidden CKD was 15.4%. Of these, 7.5% were identified by albuminuria (ACR ≥30 mg/g) with slightly decreased eGFR. Age, baseline disease, waist circumference (WC), and systolic blood pressure remained associated with CKD after multivariate analysis. The two major risk factors for hidden CKD were the presence of AH in association with DM and an increase in age. Hidden CKD was more common within people with AH and DM, and with high WC, glycosylated hemoglobin, and serum phosphorus as well as male gender and decreased serum albumin. This knowledge of risk associations can help avoid progression to CKD.

ABSTRACT

OBJECTIVE: to evaluate the factors associated with non-closure of protective ileostomy after anterior resection of the rectum with total mesorectum excision for rectal cancer, the morbidity associated with the closure of ileostomies and the rate of permanent ileostomy in patients with rectal adenocarcinoma. METHODS: we conducted a retrospective study with 174 consecutive patients diagnosed with rectal tumors, of whom 92 underwent anterior resection of the rectum with coloanal or colorectal anastomosis and protective ileostomy, with curative intent. We carried out a multivariate analysis to determine the factors associated with definite permanence of the stoma, as well as studied the morbidity of patients who underwent bowel continuity restoration. RESULTS: In the 84-month follow-up period, 54 of the 92 patients evaluated (58.7%) had the ileostomy closed and 38 (41.3%) remained with the stoma. Among the 62 patients who had the ileostomy closed, 11 (17.7%) presented some type of postoperative complication: three had ileal anastomosis dehiscence, five had intestinal obstruction, two had surgical wound infection, and one, pneumonia. Eight of these patients required a new stoma. CONCLUSION: according to the multivariate analysis, the factors associated with stoma permanence were anastomotic fistula, presence of metastases and closure of the ileostomy during chemotherapy.

ABSTRACT

BACKGROUND: When intestinal microbiota is imbalanced, a patient becomes more vulnerable to infectious complications; intervention with beneficial probiotics may help lower risk for infection. The aim of this study was to measure levels of inflammatory cytokine messenger RNA (mRNA) in surgical samples of intestinal mucosal tissues from patients who were given the probiotic Saccharomyces boulardii before undergoing colon surgery. METHODS: Thirty-three patients undergoing colon resection were randomly assigned to receive at least 7-day preoperative probiotic treatment (n = 15) or conventional (n = 18) treatment. Probiotic treatment consisted of oral lyophilized S boulardii Cytokine mRNA levels (interleukin [IL]-10, IL-1ß, IL-23A, tumor necrosis factor [TNF]-α, IL-12B, interferon-γ [INF-γ], and IL-17A) were measured in samples obtained during the operation. Postoperative infections were also assessed. RESULTS: Patients who received probiotics had significantly lower mucosal IL-1ß, IL-10, and IL-23A mRNA levels than the control group (P = .001, P = .04, and P = .03, respectively). However, mRNA expression of other cytokines did not differ between the 2 groups (P > .05). The incidence of postoperative infectious complications was 13.3% and 38.8% in probiotic and control groups, respectively (P > .05). There was no perioperative mortality in either group. The mean total length of hospital stay was similar between the groups (P > .05). CONCLUSIONS: Probiotic treatment with S boulardii downregulates both pro- and anti-inflammatory cytokines in the intestinal colonic mucosa with no statistical impact on postoperative infection rates.

ABSTRACT

OBJECTIVE: to evaluate Crohn's disease recurrence and its possible predictors in patients undergoing surgical treatment. METHODS: We conducted a retrospective study with Crohn's disease (CD) patients undergoing surgical treatment between January 1992 and January 2012, and regularly monitored at the Bowel Clinic of the Hospital das Clínicas of the UFMG. RESULTS: we evaluated 125 patients, 50.4% female, with a mean age of 46.12 years, the majority (63.2%) diagnosed between 17 and 40 years of age. The ileum was involved in 58.4%, whereas stenotic behavior was observed in 44.8%, and penetrating, in 45.6%. We observed perianal disease in 26.4% of cases. The follow-up average was 152.40 months. Surgical relapse occurred in 29.6%, with a median time of 68 months from the first operation. CONCLUSION: The ileocolic location, penetrating behavior and perianal involvement (L3B3p) were associated with increased risk of surgical recurrence.

ABSTRACT

INTRODUCTION: This study assessed male sexual function using a specific and validated questionnaire, the International Index of Erectile Function (IIEF), in patients subjected to open total mesorectal excision (OTME) and laparoscopic total mesorectal excision (LTME) and compared it with a control group. PATIENTS AND METHODS: The inclusion criteria consisted of male patients with an active sexual life before surgery subjected to OTME or LTME at the Coloproctological Unit of the Clinics Hospital, Minas Gerais Federal University, between January 2005 and September 2009. The IIEF questionnaire was used. The control group comprised 30 randomly selected men (older than 35 y of age) without previous pelvic or abdominal surgery and without any genitourinary complaints. RESULTS: Between January 2005 and September 2009, 77 male patients were subjected to total mesorectal excision, with 26 meeting the inclusion criteria and answering the questionnaire: 13 in the OTME group and 13 in the LTME group. When the 3 groups were compared in each IIEF domain, there were significant differences in erectile function (P=0.05), orgasm and ejaculation (P=0.009), sexual intercourse satisfaction (P=0.01), and overall satisfaction (P=0.025), favoring the LTME and control groups. No difference was found in sexual desire (P=0.285). CONCLUSIONS: LTME may have the benefit of preserving male sexual function compared with OTME, even in the learning curve period.

ABSTRACT

PURPOSE: Although colorectal cancer is typical in the older population, tumor onset before age 40 is not infrequent. However, the behavior, characteristics, and prognosis of this disease in young patients are unclear when compared to the older population. It is believed that young patients have a poor prognosis. We hypothesized that young patients have a poor prognosis because they have advanced-stage cancer with more aggressive pathologic features. METHODS: Using a university hospital database, we analyzed the histopathological features of three groups of patients with a diagnosis of colorectal cancer: young age group (patients 40 years and younger), intermediate age group (patients 41-80 years old), and old age group (patients 81 years and older). RESULTS: A total of 653 cases of colorectal cancer were analyzed. The young age group comprised 48 patients (7.4%), the intermediate age group comprised 538 patients (82.4%) and the old age group consisted of 67 patients (10.3%).The gender distribution was similar between the groups. The mean age of the young, intermediate, and old age groups were 34.5 (±5.0), 61.7 (±11.1) and 85.1 (±4.6) years old, respectively. The pathological features analyzed such as lymph node involvement, tumor histological classification and grade, venous, neural and lymphatic invasion, T and N classification of the TNM System, and Astler-Coller classification were similar between the age groups. CONCLUSIONS: The colorectal histopathological features in young patients are similar to older patients. More aggressive characteristics or more advanced stage are not seen in younger patients.

ABSTRACT

OBJECTIVE: To study was to investigate the associated morbidity and mortality of the restoration of intestinal continuity after Hartmann's procedure. METHODS: Hospital records of 29 patients undergoing surgery to restoration of intestinal continuity after Hartmann's procedure at Hospital das Clínicas da Universidade Federal de Minas Gerais between January 1998 and December 2006 were retrospectively analyzed. Demographic, morbidity and mortality data were colleted. RESULTS: There were 16 men and 13 women with mean age of 52.6 years. The median time between the Hartmann's procedure and the attempt of closure of colostomy was 17.6 months (range,1-84 months). The median operation time was 300 minutes (range, 180-720 min). The restoration of the continuity was successful in 27 patients (93%). Two patients had anastomotic leakage (7%) and 7 had wound infection (22%). The mortality rate was of 3.4% (1/29 patients). There were association between unsuccessful restoration of intestinal continuity and previous attempt of closure (p=.007), chemotherapy (p=.037) and long term stay with colostomy (p =.007). CONCLUSION: The interval between the Hartmann's procedure and the restoration of intestinal continuity should not be long. The patients should be aware that in some circumstances the restoration of intestinal continuity after Hartmann's procedure is not possible due to local conditions of the rectum.

ABSTRACT

OBJECTIVE: To avoid asplenic state, many approaches preserving the spleen have been proposed in the literature: splenorraphy, partial splenectomy with or without preservation of hilar vessels and splenic tissue auto-implants. Subtotal splenectomy, preserving the upper spleen pole nourished only by splenogastric vessels is an alternative when the splenic pedicle must be ligated. The purpose of this study was to evaluate the influence of partial, subtotal and total splenectomies on the distribution of Escherichia coli in the mononuclear phagocytic system. METHOD: Thirty-two rats divided into four groups were studied: sham operation (total spleen preservation), partial splenectomy, subtotal splenectomy and total splenectomy. Five weeks after surgeries, an aliquot of E. coli marked with tecnetium-99m was injected intravenously. The animals were killed 20min later and the spleen, lungs and liver were removed in order to determine the distribution of labeled bacteria. RESULTS: The amount of E. coli in the splenic tissue was greater in the intact spleen group than in the partial or subtotal splenectomy groups. Phagocytosis through the spleen did not differ between the partial and subtotal splenectomy groups. The amount of bacteria in the lungs was greater in the partial than in the subtotal splenectomy group. The distribution of labeled bacteria was greater in the liver of animals submitted to subtotal splenectomy than in the other groups. CONCLUSION: The upper splenic pole, supplied only by splenogastric vessels, has the ability to remove live bacteria from the blood stream, showing that effective blood clearance occurs even without vascularization through the splenic pedicle. Thus, the distribution of E. coli through the mononuclear phagocytic system shows different behavior depending on the type of splenectomy to which the animals are submitted.

ABSTRACT

BACKGROUND: Although lymph node and liver metastases are recognized as indications for resection of metastatic disease from colorectal cancer, carcinomatosis has not traditionally been regarded as having surgical treatment options. Reports have suggested that complete surgical removal of carcinomatosis combined with thorough irrigation of the peritoneal cavity with chemotherapy could result in longterm survival in selected patients. Proper selection factors are important because palliative surgery in these patients has not proved beneficial. STUDY DESIGN: From a database of 156 patients with carcinomatosis from colorectal cancer, a retrospective analysis of data prospectively recorded in 70 patients with complete cytoreduction was performed. Eleven clinical and treatment factors were studied in univariate and multivariable analyses using survival as an end point. RESULTS: By univariate analysis, patients with peritoneal cancer index (PCI) of<20 had a median survival of 41 months compared with 16 months for patients with PCI>20 (p=0.004). The difference in negative versus positive lymph nodes was also significant; differences in survival that were improved but not significant were present for age greater than 30 years, mucinous histology, location within the colon versus rectum, and absence of an adverse factor such as cancer perforation or obstruction present at the time of primary cancer resection. Only PCI<20 versus PCI>20 and lymph node status were significant in the multivariable analysis. CONCLUSIONS: Favorable longterm results of complete cytoreduction in patients treated for carcinomatosis are associated with a limited volume of carcinomatosis observed at the time of cytoreduction and in patients with negative lymph nodes at the time of primary operation.

ABSTRACT

BACKGROUND: Over the past 21years, we have performed more than 200 subtotal splenectomies, in which the upper splenic pole vascularized only by the gastrosplenic pole vascularized only by the gastrosplenic vessels is preserved, to treat different pathologic conditions. A meticulous follow-up of the postoperative results of this procedure is of fundamental importance. METHODS: All patients undergoing subtotal splenectomy were invited to be reviewed. A total of 86 patients who had undergone surgery 1-20years ago were gathered; the surgical procedure was performed for one of the following conditions: portal hypertension due to schistosomiasis (n=43), trauma (n=31), Gaucher's disease (n=4), myeloid hepatosplenomegaly due to myelofibrosis (n=3), splenomegalic retarded growth and sexual development (n=2), severe pain due to splenic ischemia (n=2) and pancreatic cystadenoma (n=1). Patients underwent a hematological examination, an immunological assessment, abdominal ultrasonography, computed tomography, scintigraphy and endoscopy. RESULTS: Increased white blood cell count and platelets were the only hematological abnormalities. No immunological deficit was found. Esophageal varices were still present in patients who underwent surgery because of portal hypertension although without rebleeding. The ultrasound, tomography and scintigraphy examinations confirmed the presence of functional splenic remnants without significant size alteration. CONCLUSIONS: Subtotal splenectomy seems to be a safe procedure that can be useful in treating conditions involving the spleen. The functions of the splenic remnants are preserved during long periods of time.

ABSTRACT

PURPOSE OF REVIEW: Early nutrition has been evaluated and used as a possible strategy to decrease the negative impact of the metabolic response to injury and postoperative ileus. The metabolic response to injury, be it surgical or traumatic, is a physiological mechanism that, according to the magnitude and duration of the event, can impact on the patient's morbidity and survival. The adequate initial approach is a determinant factor that might influence its outcome. Simultaneously, gastrointestinal tract motility is transiently impaired, leading to the so-called postoperative ileus. The latter not only causes patient discomfort, but is also related to abdominal complications and worsening of the nutritional status, as well as increased length of hospital stay and costs. RECENT FINDINGS: Multimodal surgical strategies such as preoperative intake of a carbohydrate drink, together with patient education of the postoperative care plan, efficacious analgesia and early nutrition have been described to significantly decrease the stress response and improve the ileus. Therefore, these strategies accelerate rehabilitation and, as a consequence, decrease complications and length of hospital stay and its related costs. SUMMARY: Understanding perioperative pathophysiology and implementing care regimes through a multimodal approach in order to reduce the stress of the operation and the related postoperative ileus are major challenges. These factors will certainly impact on patient outcomes.
