BACKGROUND: Sickness behavioral changes elicited by inflammation may become prolonged and dysfunctional in patients with chronic disease, such as chronic hepatitis C (CHC). Neuroimaging studies show that the basal ganglia and insula are sensitive to systemic inflammation. AIM: To elucidate the clinical and neurobiological aspects of prolonged illnesses in patients with CHC. METHODS: Thirty-five CHC patients not treated with interferon-α or other antiviral therapy, and 30 control subjects matched for age and sex, were evaluated for perceived stress (perceived stress scale; PSS), depression (PHQ-9), fatigue and irritability through a visual analog scale (VAS), as well as serum levels of interleukin-6 (IL-6), prostaglandin E2 (PGE2 ) and oxidative stress markers...

Objective: To retrospectively evaluate the results after applying a protocol for treating acute infections in cases of total knee arthroplasty and to establish factors predictive of success or failure. Methods: Thirty-two patients who were diagnosed with acute infection of the knee following total arthroplasty between 2004 and 2009 were retrospectively evaluated. Infections following arthroplasty were treated in accordance with the protocol for acute infections following arthroscopy recommended at our institution...

Introducción. Uno de los principales factores de riesgo del carcinoma hepatocelular es el consumo crónico de alcohol. En estudios en diferentes poblaciones, se sugiere que las variantes genéticas de las enzimas que participan en el metabolismo del alcohol, como la alcohol deshidrogenasa (ADH) y la citocromo P450 (CYP2E1), estarían asociadas con riesgo de enfermedades hepáticas terminales.Objetivo. Identificar y caracterizar las variantes alélicas de los genes ADH1B, ADH1C y CYP2E1 en pacientes colombianos con diagnóstico de cirrosis y carcinoma hepatocelular...

The present study focused on an environmental scandal that occurred in Italy, the Land of Fires toxic waste scandal, which caused consumer concerns related to the safety of food produced in the affected region, as well as massive market reduction in products associated with the polluted area. Based on a representative sample of Italian households ( N = 1134), this study applied an extended Theory of Planned Behavior (TPB) model to analyze consumer purchases of regional food products after this environmental hazard...

OBJECTIVE: To determine the added value of multimodal structural magnetic resonance imaging (MRI) to language assessment in the differential diagnosis of primary progressive aphasia (PPA) variants. METHODS: 59 PPA patients [29 nonfluent (nfvPPA), 15 semantic (svPPA), 15 logopenic (lvPPA)] and 38 healthy controls underwent 3D T1-weighted and diffusion tensor (DT) MRI. PPA patients also performed a comprehensive language assessment. Cortical thickness measures and DT MRI indices of white matter tract integrity were obtained...

AIM: To increase the number of available grafts. METHODS: This is a single-center comparative analysis performed between April 1986 and May 2016. Two hundred and twelve liver transplantation (LT) were performed with donors ≥ 70 years old (study group). Then, we selected the first cases that were performed with donors < 70 years old immediately after the ones that were performed with donors ≥ 70 years old (control group). RESULTS: Graft and patient survivals were similar between both groups without increasing the risk of complications, especially primary non-function, vascular complications and biliary complications...

Background: Airway hemangiomas are congenital neoplasms of low incidence. Its clinical presentation consists of obstruction of the upper airway with progressive dyspnea and stridor and the life of the patient at risk. Infantile hemangiomas have an incidence at birth of 2%, increasing to 9% at 12 months of life. Almost 60% of childhood hemangiomas affect the head and neck region. However, localization in the upper airway is not as frequent and it is only reported in 1.8% of patients with cutaneous hemangiomas...

OBJECTIVES: To identify the psychopathological, cognitive, functional, physical health and inflammatory markers that differentiate between early-stage schizophrenia (ESSCH) and late-stage schizophrenia (LSSCH). METHODS: Cross-sectional, naturalistic study of 104 patients with SCH. The sample was divided in two groups: 35 ESSCH (≤7 years' duration of illness) and 69 LSSCH (>10 years' duration of illness). STATISTICAL ANALYSIS: chi-square test and Student's t-test and ANCOVA (or Quade test) controlling for age, sex, BMI and number of cigarettes/day...

Malignant pleural effusion (MPE) is a common and complex manifestation of advanced stage cancer. Treatment options have trended towards less invasive approaches such as intrapleural catheter drainage, however this technique is not without morbidity and not suitable for every patient. A troublesome scenario arises when an MPE is secondarily infected in the setting of an indwelling catheter, given both the high frequency of recurrence of such fluid and the presence of a foreign body. Further, quality literature surrounding this specific management issue is sparse and thus practice is heterogeneous...

We report a case of intrauterine infection by Toxoplasma gondii, Chikungunya and Zika viruses in a Colombian woman from the southern part of the country. The patient attended prenatal care in the second trimester of her pregnancy and she informed that in the first trimester she had presented with clinical symptoms compatible with Zika virus infection. Amniotic fluid PCR assays showed infection by T. gondii, chikungunya and Zika viruses. Diagnostic imaging showed fetal malformation of the central nervous system...

BACKGROUND: Studies show that Toll-like receptors (TLRs), members of the innate immune system, might participate in the pathogenesis of the major depressive disorder (MDD). However, evidence of this participation in the brain of patients with MDD has been elusive. METHODS: This work explores whether the protein expression by immunodetection assays (Western blot) of elements of TLR-4 pathways controlling inflammation and the oxidative/nitrosative stress are altered in postmortem dorsolateral prefrontal cortex of subjects with MDD...

Objective: to compare two models of experimental glaucoma by induction of ocular hypertension in rabbits. Materials and methods: Sixteen New Zealand female rabbits, 2-3 kg were used. Model A (n=6): cauterization of episcleral and perilimbar veins of the right eye (RE) with surgical electrocautery. Model B (n=10): Injection of ?-chymotrypsin in posterior chamber of RE. Intraocular pressure (IOP) was measured before and after the induction of ocular hypertension (OHT), once a week at the same time of day for 40 days, with a manual tonometer...

The present research focused on water intake (WI) in young adults. Study 1 (N = 272) was a correlational study and showed affective attitude, perceived behavioural control, past behaviour and anticipated negative affective reactions (ANAR) to predict WI intentions. It also showed intentions, instrumental attitude, perceived behavioural control, and past behaviour to predict WI prospectively. In addition, ANAR moderates the relationship between intention and future water intake (WI). Study 2 (N = 197) was an experimental study and showed that daily text messages targeting ANAR plus a self-monitoring manipulation increased WI immediately after the intervention although this effect did not persist one month later...

Lately, the integration of two-dimensional materials into semiconductor devices has allowed the modification of their effective index by simply applying a modest voltage (between 0 and 3 volts). In this work, we present a device composed of two evanescently coupled silicon microring resonators where both rings have a graphene layer on top. This design is aimed to produce frequency combs with transmission characteristics controlled upon voltage application to the graphene layer. We numerically analyze the device response as a function of the incident wavelength and applied voltage...
