Comparative Analysis of the Quality of Life in the Pretreatment of Head and Neck Cancer Patients According to Tumor Site.

 Head and neck cancer (HNC) and its treatment can cause physical, psychological, and quality of life (QoL) damage, because it can disturb the physiology of eating, breathing, speaking, and compromise self-image.  To evaluate the QoL of the pretreatment of patients diagnosed with head and neck cancer according to the anatomical location of the tumor.  A descriptive, cross-sectional study was performed on a sample of 144 patients undergoing pretreatment for cancer from February 2017 to July 2019.

Nighttime salivary cortisol as a biomarker of stress and an indicator of worsening quality of life in patients with head and neck cancer: A cross-sectional study.

Background: Head and neck cancer (HNC) is a generic term defined on an anatomical-topographic basis to describe malignant tumors located in the oral cavity, pharynx, larynx, and thyroid. A situation commonly presented by individuals with cancer is stress, with evidence indicating a close relationship between stress, behavior, and the immune system with the development and progression of cancer.

Aim: To assess the association between stress levels and quality of life among individuals with HNC.

Urinary tract infection in non-hospitalized patients with cirrhosis and no symptoms of urinary tract infection: a case series study.

Bacterial infections are important factors in decompensation, and they increase the mortality rate of patients with liver cirrhosis. The most common infections among these patients are spontaneous bacterial peritonitis, pneumonia, skin infections and urinary tract infections (UTI). This transversal study evaluated the frequency of UTI in non-hospitalized patients with cirrhosis followed in a hepatology outpatient unit.

Anti-Golgi complex antibodies during pegylated-interferon therapy for hepatitis C.

Background/aim: Pegylated interferon (Peg-IFN) plus ribavirin is the standard therapy for hepatitis C. Peg-IFN has several antiviral mechanisms, but its role in hepatitis C treatment seems to be related to its immunomodulatory effect. Ribavirin, an antiviral agent, potentiates IFN activity when added to it.

Peripheral insulin resistance during treatment of chronic hepatitis C with peguilated interferon plus ribavirin.

Unlabelled: Patients with hepatitis C virus (HCV) infection present higher risk of developing type-2 diabetes mellitus (DM). However, the mechanism of this association and the role of antiviral treatment are still unclear. The objective of this study was to investigate the relationship between the use of peguilated interferon and the development of insulin resistance (IR) in these patients.

[Frequency and implications of autoantibodies in acute viral hepatitis].

There are interactions between hepatotropic viruses and the host immune system, which could contribute to liver damage in viral hepatitis. The aim of this study was to investigate the frequency of autoantibodies in patients with acute viral hepatitis and their relationship with biochemical activity, severity of acute illness and chronicity rate. From 1992 to 2000, 156 patients with acute viral hepatitis were enrolled in a prospective study.
