Left Atrial Volume versus Coronary Artery Calcium Score in Patients on Peritoneal Dialysis: An Observational Study.

The coronary artery calcium score and left atrial volume have been shown to predict the incidence of acute myocardial infarction and death from cardiovascular disease in patients undergoing peritoneal dialysis. However, the association between these factors has not been well-established. This cross-sectional, prospective, single-center study was conducted on patients undergoing outpatient peritoneal dialysis, who were followed up at a university hospital between March 2018 and August 2019.

Association between chronic kidney disease stages and changes in ambulatory blood pressure monitoring parameters.

Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM).

Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM.

Advances in Peritoneal Dialysis in Acute Kidney Injury.

In the 1970s, acute peritoneal dialysis (PD) was widely accepted for the treatment of acute kidney injury (AKI), but this practice has declined in favor of extracorporeal therapies, mainly in developed world. The lack of familiarity with the use of PD in critically ill patients has also led to a lack of use even among those receiving maintenance PD. Renewed interest in the use of PD for AKI therapy has emerged due to its increasing use in low- and middle-income countries due to its lower cost and minimal infrastructural requirements.

Urgent-Start Peritoneal Dialysis: Brazilian Experience.

Introduction: Unplanned peritoneal dialysis (PD) is an important option for chronic kidney disease (CKD) patients requiring kidney replacement therapy urgently as it offers the convenience of home-based therapy. The objective of this study was to assess the Brazilian urgent-start PD program in three different dialysis centers where there is shortage of hemodialysis (HD) beds.

Methods: This prospective, multicentric cohort study included incident patients with stage 5 CKD and no permanent vascular access established who started urgent PD between July 2014 and July 2020 in three different hospitals.

Association between urinary sodium excretion and hard outcomes in non-dialysis chronic kidney disease patients.

Background: Restriction of sodium intake is routinely recommended for patients with chronic kidney disease (CKD). Whether or not sodium intake is associated with the progression of CKD and mortality remains uncertain. We evaluated the association between urinary sodium excretion (as a surrogate for sodium intake) with the occurrence of renal failure and mortality in patients with non-dialytic CKD.

Relationship of Structural and Tissue Components of Full-Layer Skin Wound and Mathematical Modeling of the Healing Process.

We studied the relationship between structural components of the wound (scab, leukocyte shaft, newly formed epithelium, and granulation tissue) and tissue components (epithelial and connective tissue) during spontaneous healing of skin wounds in rats. The regenerate structures were evaluated by microscopic morphometry. The number of vessels in 10 fields of view was calculated (at ×600), the dimensions of newly formed regenerate structures were determined: height of the scab, leukocyte shaft, granulation tissue, the border zone of the epithelium, and the length of the epithelial wedge.

Association between Sodium Intake and Urinary Fractional Albumin and Immunoglobulin G Excretion in Chronic Nondialytic Renal Disease: A Prospective Longitudinal Study.

Background/aims: Previous studies reported that fractional clearance of urinary proteins is better than total proteinuria in predicting chronic kidney disease (CKD) progression. However, the role of sodium in the fractional excretion of proteins has not been established. We aimed to evaluate the association between sodium intake and fractional albumin and immunoglobulin G (IgG) excretion in nondialytic CKD.

Influence of the intra-peritoneal segment of the swan neck peritoneal catheter on infectious and mechanical complications and technique survival.

Background: There is no consensus about the preferable type of catheter for successful peritoneal dialysis. Intra- and extra-peritoneal catheter configuration may be associated with mechanical and infectious complications affecting technique survival. The objective of this study was to compare the mechanical and infectious complications of coiled versus straight swan neck (SN) peritoneal dialysis catheters.

Effect of the Spiritist "passe" energy therapy in reducing anxiety in volunteers: A randomized controlled trial.

Background: In Brazil, one of the most used energy therapies is the Spiritist "passe", which is practiced by Spiritist healers. Although experimental studies have demonstrated the effectiveness of different energy therapies in reducing anxiety and pain, little is known about the effect of the Spiritist "passe" on health outcomes. Therefore, the present study aimed at evaluating the effectiveness of "passe" energy therapy in reducing anxiety symptoms.

Peritoneal dialysis can be an option for unplanned chronic dialysis: initial results from a developing country.

Aim: Starting dialysis in an unplanned manner is frequent situation in dialysis center even for patients with regular nephrology follow-up. Peritoneal dialysis (PD) appears as an option for unplanned initiation of chronic dialysis, offering the advantage of not using central venous catheters and preserving of residual renal function. Since July 2014, we have offered PD as urgent start for chronic kidney disease (CKD) patients.

Left ventricular mass behaviour in hemodialysis patients during 17 years.

Introduction: Ventricular hypertrophy is frequent in dialysis patients and is associated with an ominous prognosis. It is not knowledge if this ventricular change is growing or decreasing in hemodialysis patients.

Objective: To assess left ventricular hypertrophy behaviour during 17 years in patients of a university dialysis center, as well as to verify the possible causes of this behavior.

[Redox-dependent ferric oxide nanoparticles loaded with doxorubicin and their influence on the functions of mitochondria].

The spectral, fluorescent and functional properties of ferric oxide and ferric hydroxide nanoparticles loaded with doxorubicin and stabilized with citric acid or lysine were studied in comparison with free doxorubicin. Their effect on the opening of calcium-induced mitochondrial pore and the possibility of the controlled release of doxorubicin under the influence of redox stimuli were investigated. The data show that the effect of nanoparticles on mitochondria depends on the type of a stabilizer.

[Antitumor and antiproliferative action of the steroidal cytostatic antiestrogen cytestrol acetate on hormone-dependent tumor models].

Cytestrole acetate (CA), in the structure of which the steroidal antiestrogen component is associated with bis-β-cloroethylamino group, exhibits a strong cytotoxic activity against hormone-dependent cancer cell lines (CaOV, HeLa, MCF-7). In doxorubicin-resistant MCF-7 cells, CA potentiates the cytotoxic effect of etoposide and doxorubicin, and the IC50 for CA in these cells is 40 times lower than that for tamoxifen (TAM). In transplantable mice breast adenocarcinoma Ca-755, the therapeutic CA dose is 25 mg/kg when administered subcutaneously in oil solution for 5 days.

Combined effect of bis-beta-chloroethylamine estrogen derivatives and doxorubicin on proliferation of sensitive and resistant MCF-7 cells.

The sensitivity of normal (MCF-7/WT) and doxorubicin-resistant (MCF-7/R) breast cancer cells to the antiproliferative effect of ethynylestradiol 11alpha-derivatives with the cytostatic residue in the 3-position of the steroid ring (antiestrogen cytostatics) was studied by evaluating cell viability using methylthiazole tetrazolium staining. The antiproliferative effects of these agents on cell lines in the presence of doxorubicin were compared. Antiestrogen cytostatics produced weaker cytostatic effect on MCF-7/WT cells, but more potent cytostatic effect on MCF-7/WT cells compared to those of doxorubicin.
