Association between KRAS mutation and alcohol consumption in Brazilian patients with colorectal cancer.

Colorectal cancer (CRC) is a leading cause of morbidity and mortality worldwide. Detection before metastasis and efficient treatment of disease significantly improve patient survival and quality of life. However, limitations in diagnosis and postoperative surveillance are associated with low CRC detection and survival rates.

Hypertriglyceridemic waist phenotype and associated factors in individuals with arterial hypertension and/or diabetes mellitus.

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).

Low-grade albuminuria in adult and elderly individuals with diabetes mellitus and arterial hypertension accompanied by Primary Health Care.

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).

Background: Low anterior resection syndrome has a negative impact on quality of life. Intestinal irrigation is a method of lavage consisting of a scheduled evacuation.

Objective: This study aims to evaluate functional and quality-of-life outcomes in patients with low anterior resection syndrome after transanal irrigation using a colostomy irrigation system.

Surgical results and quality of life of patients submitted to restorative proctocolectomy and ileal pouch-anal anastomosis.

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.

Prevalence of chronic kidney disease in Brazilians with arterial hypertension and/or diabetes mellitus.

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.

Survival and analysis of predictors of mortality in patients undergoing replacement renal therapy: a 20-year cohort.

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.

Factors preventing restoration of bowel continuity in patients with rectal cancer submitted to anterior rectal resection and protective ileostomy.

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.

CLINICAL, EPIDEMIOLOGIC, AND ENDOSCOPIC PROFILE IN CHILDREN AND ADOLESCENTS WITH COLONIC POLYPS IN TWO REFERENCE CENTERS.

Background: The main goal of this paper is to investigate the frequency, clinical profile, and endoscopic findings of children and teenagers submitted to colonoscopies.

Methods: Patients of below 18 years of age, diagnosed with polyps by means of colonoscopies at two reference centers of pediatric endoscopy were followed-up between 2002 and 2012.

Intra-observer reliability in three-dimensional kinematic analysis of sacroiliac joint mobility.

[Purpose] Physical therapists, osteopathic practitioners, and chiropractors often perform manual tests to evaluate sacroiliac joint (SIJ) mobility. However, the available evidence demonstrates an absence of reliability in these tests and in investigations with kinematic analysis. The aim of this study was to verify the three-dimensional kinematic reliability in SIJ movement measurements.

Randomized Clinical Trial: Impact of Oral Administration of Saccharomyces boulardii on Gene Expression of Intestinal Cytokines in Patients Undergoing Colon Resection.

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.

Pregnancy after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in pseudomyxoma peritonei.

Pseudomyxoma peritonei is usually a benign tumor that is slightly more common in women. However, it requires aggressive surgical treatment and chemotherapy, often compromising future reproductive function. This report presents a case of pregnancy in a 35-year-old woman who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for treatment of pseudomyxoma peritonei.

Male sexual function after total mesorectal excision: a comparison between laparoscopic and open surgery during the learning curve period.

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.

A simplified rehabilitation program for patients undergoing elective colonic surgery--randomized controlled clinical trial.

Background: We have proposed a simplified perioperative rehabilitation program for elective colonic surgery that is focused on early oral nutrition and that could reduce hospital stay and postoperative ileus time without raising complications and readmission rates.

Patients And Methods: Fifty-four patients admitted for elective colonic surgery were prospectively randomized into two groups: (1) an early feeding group (EFG)-on the first postoperative day, patients initially received a oral liquid diet and were advanced to a regular diet within the next 24 h as tolerated and at their discretion; (2) a traditional care group-patients were managed by nothing per orus until the elimination of the first flatus and then submitted to an oral liquid diet, followed by a regular diet within the next 24 h as described for the EFG. All patients followed a well-defined, simplified rehabilitation program.

Effect of spleen surgeries on Escherichia coli distribution on the mononuclear phagocytic system.

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.

Late follow-up of patients submitted to subtotal splenectomy.

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.
