Cognitive impairment in a Colombian cohort of patients with systemic lupus erythematosus: A cross-sectional study.

Context: Cognitive deficits are neuropsychiatric syndromes associated with systemic lupus erythematosus. In our context, there are no data on the frequency of cognitive deficit as a manifestation of neuropsychiatric SLE or the associated conditions.

Objective: To define determinants of cognitive deficit in a cohort of Colombian patients with SLE attending a third-level hospital.

Predicting Peritoneal Carcinomatosis in Locally Advanced Gastric Cancer: The Significance of Tumor Markers in the Peritoneal Washing.

Purpose: Gastric cancer is the fifth most common malignant tumor worldwide. Many attempts have been made over the years to investigate the relationship between tumor markers and the risk of recurrence. This study aims to explore the predictive value of tumor markers measured in peritoneal washing during staging laparoscopy, regarding peritoneal carcinomatosis and mortality within 1 year.

Differences Between Right and Left Colon Cancer in Beira Interior.

Introduction Colorectal cancer (CRC) is the second most common cancer in Portugal and worldwide, with a high mortality rate, especially in more advanced stages. In recent decades, there has been a growing interest in the distinction between right colorectal carcinoma (RCC) and left colorectal carcinoma (LCC) due to the different presentation, treatment, and prognosis. Studies show that RCC and LCC have different clinical and biological characteristics, being considered two distinct entities.

A 68-Year-Old Woman Presenting with Recurrent Abdominal Pain and a Diagnosis of a Presacral Retroperitoneal Benign Schwannoma that Mimicked an Ovarian Tumor on Pelvic Magnetic Resonance Imagining.

BACKGROUND Schwannomas are benign tumors and their appearance in the pelvic region is rare and poses a major diagnostic problem. They can be sporadic or associated with genetical syndromes. They have a slow growth rate and may be asymptomatic for many years.

Episodic Past, Future, and counterfactual thinking in Relapsing-Remitting Multiple sclerosis.

Multiple sclerosis (MS) is a progressive disease characterized by widespread white matter lesions in the brain and spinal cord. In addition to well-characterized motor deficits, MS results in cognitive impairments in several domains, notably in episodic autobiographical memory. Recent studies have also revealed that patients with MS exhibit deficits in episodic future thinking, i.

Small Bowel Obstruction Due to Incarcerated Obturator Hernia: Successfull Surgical Management with Modified Mesh-Plug Hernioplasty.

BACKGROUND Obturator hernia is an uncommon (0.07-1% incidence rate) subtype of hernia of the abdominal wall, with its incarceration being a rare cause of bowel obstruction. Obturator hernia has a higher incidence in elderly women and in malnourished people.

Establishment, spread and early impacts of the first biocontrol agent against an invasive plant in continental Europe.

Classical biocontrol is key for the successful management of invasive alien plants; yet, it is still relatively new in Europe. Although post-release monitoring is essential to evaluate the effectiveness of a biocontrol agent, it is often neglected. This study reports the detailed post-release monitoring of the first biocontrol agent intentionally introduced against an invasive plant in continental Europe.

Asymptomatic large duodenal GIST - An incidental finding in abdominopelvic ultrasonography: A case report.

Introduction: Duodenal GISTs are rare mesenchymal tumors of the digestive tract. They usually present as gastrointestinal bleeding or non-specific abdominal pain, but they can also be asymptomatic. High-risk GISTs have malignant potential.

Sample container for high-resolution neutron imaging of spent nuclear fuel cladding sections.

In this work, for the first time, high-resolution neutron imaging (true spatial resolution of 13 μm) is used for irradiated nuclear fuel cladding, applying an adapted procedure for transfer, handling, and measurements of highly radioactive samples in combination with the neutron microscope detector at Paul Scherrer Institut. A sample container referred to as an active box for high-resolution neutron imaging of highly active spent nuclear fuel cladding sections was developed. Sections of unirradiated and irradiated cladding of duplex type, having a liner, with hydrogen average concentrations of 420 wppm and 450 wppm were investigated using this device.

Sclerosing angiomatoid nodular transformation of the spleen: case report of a metastatic carcinoma-simulating disorder.

Sclerosing angiomatoid nodular transformation (SANT) is a rare nonneoplastic splenic disorder of unknown etiopathogenesis. This condition is usually found incidentally on imaging studies. Because of its similar features, SANT can wrongly be described as metastatic carcinoma.

Wunderlich's Syndrome, or Spontaneous Retroperitoneal Hemorrhage, in a Patient with Tuberous Sclerosis and Bilateral Renal Angiomyolipoma.

BACKGROUND Wunderlich's syndrome, or spontaneous non-traumatic retroperitoneal hemorrhage, can be a life-threatening event. Renal angiomyolipoma is a rare benign tumor that can occur sporadically, or in association with tuberous sclerosis. A case of spontaneous retroperitoneal hemorrhage in a patient with tuberous sclerosis and bilateral renal angiomyolipoma is presented.

Characterization of the Fe-rich corner of Al-Fe-Si-Ti.

The quaternary system Al-Fe-Si-Ti was studied in the iron-rich corner for sections at 50, 60 and 70 at.% Fe at 900 °C. Isothermal phase equilibria were investigated by a combination of optical microscopy, X-ray powder diffraction (XRD) followed by Rietveld refinement and Electron Probe Microanalysis (EPMA).

Phase equilibria and structural investigations in the Ni-poor part of the system Al-Ge-Ni.

The ternary phase diagram Al-Ge-Ni was investigated between 0 and 50 at.% Ni by a combination of differential thermal analysis (DTA), powder- and single-crystal X-ray diffraction (XRD), metallography and electron probe microanalysis (EPMA). Ternary phase equilibria and accurate phase compositions of the equilibrium phases were determined within two partial isothermal sections at 400 and 700 °C, respectively.

Analyzing feature distinctiveness in the processing of living and non-living concepts in Alzheimer's disease.

The conceptual structure account (CSA) is a model specifying the role of the living and non-living domain dichotomy in the structure of semantic memory. According to this model, feature distinctiveness and the perceptual-functional inter-correlation of concepts are assumed to play a major role in impairing the ability to discriminate between living and non-living concepts in Alzheimer's disease (AD). The hypothesis was tested in this study by using naming and sorting tasks traditionally considered as assessing distinctiveness, and a property verification task where distinctiveness and perceptual-functional inter-correlation were objectively controlled against norms especially created for this purpose.

[Deficit of access or storage: semantic memory processing in Alzheimer disease].

This study investigates three principal aspects of semantic memory processing in Alzheimer's disease: word finding, knowledge of the specific and generic attributes of concepts. Semantic memory is assessed by a range of verbal and visual tasks differentiated according to their level of complexity. Our hypothesis is that the processing of these types of information is modulated by the degree of effortful processing required by the tasks.
