Association between visual impairment and depression in the elderly: a systematic review.

A systematic review was conducted to investigate the relationship between visual impairment and depression in the elderly. We searched electronic databases (LILACS, SciELO, MEDLINE, and Cochrane Central Register of Controlled Trials) from inception to August 2014 and researched the described references. The search strategy used the following terms: (visual impairment or blindness) and (elderly) and (depression).

Neuraxial anaesthesia for lower-limb revascularization.

Background: Lower-limb revascularization is a surgical procedure that is performed to restore an adequate blood supply to the limbs. Lower-limb revascularization surgery is used to reduce pain and sometimes to improve lower-limb function. Neuraxial anaesthesia is an anaesthetic technique that uses local anaesthetics next to the spinal cord to block nerve function.

Analysis of the immunohistochemical expressions of p53, bcl-2 and Ki-67 in colorectal adenocarcinoma and their correlations with the prognostic factors.

Context: Search of tumors markers that allow treatment with higher survival rates, and indicate the response to treatment and recurrence of cancer

Objective: To analyze the immunoexpression of the proteins p53, bcl-2 and Ki-67 in colorectal adenocarcinoma and correlate them with the clinical-pathological prognostic factors.

Method: Tissue microarray paraffin blocks were made from colorectal adenocarcinoma tissue resected from 82 patients who had undergone surgery but not chemotherapy or radiotherapy, at "Hospital São Paulo", São Paulo, SP, Brazil, between 2002 and 2005. Thin sections (4 microm) were subjected to immunohistochemical reactions, and immunoexpression staining scores were obtained.

Applications of magnesium sulfate in obstetrics and anesthesia.

Background And Objectives: Magnesium is predominantly an intracellular ion. Its blocking effects on NMDA receptors are responsible for the analgesic and sedative characteristics of this ion. The objective of this study was to review the physiology, pharmacology, and decreased plasma levels of magnesium, as well as its applications in obstetrics and anesthesia.

Neuraxial anaesthesia for lower-limb revascularization.

Background: Lower-limb revascularization surgery is used to reduce pain and sometimes to improve lower-limb function. The type of anaesthesia used during lower-limb revascularization may affect the risks of both good and bad outcomes.

Objectives: To determine the rates of death and major complications with spinal and epidural anaesthesia compared with other types of anaesthesia for lower-limb revascularization.

Metalloproteinase-1, metalloproteinase-7, and p53 immunoexpression and their correlation with clinicopathological prognostic factors in colorectal adenocarcinoma.

Aim: The aim of this study was to analyze the immunoexpression of metalloproteinase-1, metalloproteinase-7, and p53 in colorectal adenocarcinoma, and to correlate this with clinicopathological prognostic factors.

Material And Methods: Formalin-fixed paraffin-embedded tumor tissue from 82 patients was analyzed by means of immunohistochemistry, using the streptavidin-biotin method and the tissue microarray technique. Protein tissue expression was correlated with the variables of the degree of cell differentiation, stage, relapse-free survival, recurrence, survival, and specific mortality.

Correlation between the immunohistochemical expressions of MMP-1, MMP-7 and VEGF and prognostic factors in colorectal adenocarcinoma.

Purpose: To analyze the expression of metalloproteinase-1, metalloproteinase-7 and vascular endothelial growth factor (VEGF) in colorectal adenocarcinoma, and to correlate these with the clinical-pathological prognostic factors.

Methods: Tumor tissue from 82 patients was fixed in formalin and embedded in paraffin blocks. These samples were analyzed by means of the streptavidin-biotin immunohistochemical method, using the tissue microarray technique.

Artificial oxygen carriers as a possible alternative to red cells in clinical practice.

Fluid resuscitation is intended to eliminate microcirculatory disorders and restore adequate tissue oxygenation. The safety limits for a restrictive transfusion policy are given by patients' individual tolerance of acute normovolemic anemia. Artificial oxygen carriers based on perfluorocarbon or hemoglobin are attractive alternatives to allogenic red blood cells.

Chemoprevention by celecoxib in reflux-induced gastric adenocarcinoma in Wistar rats that underwent gastrojejunostomy.

Purpose: To evaluate chemoprevention by celecoxib in cases of reflux-induced gastric adenocarcinoma, in Wistar rats that underwent gastrojejunostomy.

Methods: Sixty male Wistar rats of average age three months underwent surgery and were distributed into three groups: group 1, exploratory laparotomy; group 2, gastrojejunostomy; and group 3, gastrojejunostomy and daily celecoxib administration. After 53 weeks, the animals were sacrificed.

Neuroaxis block compared to general anesthesia for revascularization of the lower limbs in the elderly. A systematic review with metanalysis of randomized clinical studies.

Background And Objectives: Currently, it is controversial on whether neuroaxis block (NB) is more effective than general anesthesia (GA) in elderly individuals undergoing non-cardiac surgeries. The objective of this study was to determine the efficiency of NB in comparison to GA for revascularization of the lower limbs (RLL) in the elderly.

Methods: A search of the following data base was conducted: MEDLINE (1955 to 2007), CINHAL (1982 to 2007), EMBASE (1980 to 2007), LILACS (1982 to 2007), and ISI (1945 to 2007).

Assessing the quality of random clinical anesthesiology trials published on the Brazilian Journal of Anesthesiology from 2005 to 2008.

Background And Objectives: A random clinical trial (RCT) is defined as a study involving intervention and control groups with random distribution of the participants. The objective of the present study was to assess the quality of RCT in anesthesiology published during a specific time.

Design Of The Study: descriptive.

Prospective study on the effects of a polypropylene prosthesis on testicular volume and arterial flow in patients undergoing surgical correction for inguinal hernia.

Purpose: To evaluate testicular volume and arterial flow in patients undergoing surgical correction for inguinal hernia, with polypropylene prosthesis.

Methods: This was an observational prospective clinical study on 39 male patients with unilateral inguinal hernia of types III A and III B according to the Nyhus classification who underwent surgical correction with implantation of a polypropylene prosthesis by means of the Lichtenstein technique. The patients were evaluated using Doppler ultrasound before the operation and selectively at the third and sixth months after the operation.

Analysis of bacteremia occurring in the presence of obstruction of the left colon in rats submitted to transoperative antegrade mechanical lavage.

With the objective of determining the association between bacteremia and transoperative antegrade mechanical lavage of the colon in an experimental model of obstruction of the left colon in rats, 40 male Wistar rats aged between 90 and 120 days were divided randomly into four groups: A, with intestinal obstruction and with mechanical lavage of the colon; B, with intestinal obstruction and without mechanical lavage of the colon; C, without intestinal obstruction and with mechanical lavage of the colon; and D, without intestinal obstruction and without mechanical lavage of the colon. Analysis of the results showed that there was no bacteremia in the animals in the sham group. On the other hand, bacterial growth in blood cultures was found in three animals (30%) in group C and in four animals (40%) in group B.
