Oculopharyngeal muscular dystrophy, myasthenia gravis, systemic lupus erythematosus: overlap and interactions.

Ptosis and proximal weakness may develop in multiple diseases including oculopharyngeal muscular dystrophy (OPMD) and myasthenia gravis (MG). These two entities can be challenging to differentiate since they may have important clinical and neurophysiological overlap. Systemic lupus erythematosus (SLE), a common autoimmune disease, has been described in association with MG.

Mathematical model of the dynamics of transmission and control of sporotrichosis in domestic cats.

Sporotrichosis is a subcutaneous mycosis with a global distribution, also known as "rose gardener's disease". Brazil is experiencing a rapid spread of the zoonotic transmission of of Sporothrix brasiliensis, the main etiological agent of this disease in this country, affecting domestic felines. Cost-effective interventions need to be developed to control this emergent public health problem.

High Rates of Sexualized Drug Use or Chemsex among Brazilian Transgender Women and Young Sexual and Gender Minorities.

(1) Background: We aimed to estimate sexualized drug use (SDU) prevalence and its predictors among sexual and gender minorities. (2) Methods: We used an online and on-site survey to enroll sexual/gender minorities people between October-December/2020, and multivariate logistic regression to obtain SDU correlates. (3) Results: We enrolled 3924 individuals (280 transgender women [TGW], 3553 men who have sex with men [MSM], and 91 non-binary), 29.

NIR and H qNMR methods coupled to chemometrics discriminate the chemotypes of the gastroprotective herb Egletes viscosa.

Egletes viscosa is a Brazilian medicinal herb consumed as flower bud tea due to its gastroprotective properties. This plant possesses two essential oil-based chemical varieties: trans-pinocarveyl acetate-rich chemotype A and cis-isopinocarveyl acetate- rich chemotype B. Therefore, we developed two simple, fast and reliable methods for discrimination of E.

Maximum acceleration performance of professional soccer players in linear sprints: Is there a direct connection with change-of-direction ability?

The purpose of this study was to examine the selective influences of the maximum acceleration capability on change of direction (COD) speed, COD deficit, linear sprint speed, sprint momentum, and loaded and unloaded vertical jump performances in forty-nine male professional soccer players (24.3 ± 4.2 years; 75.

Breast tumor classification in ultrasound images using neural networks with improved generalization methods.

Mammography, scintimammography and ultrasound images have been used to increase the specificity of breast cancer image diagnosis. Concerning breast cancer image diagnosis with ultrasound, some results found in the literature show better performance of morphological features in breast cancer lesion differentiation and that a reduced set of features shows a better performance than a large set of features. In this study we evaluated the performance of neural network classifiers, with different training stop criteria: mean square error, early stop and regularization.

The Use of Propolis in Micro/Nanostructured Pharmaceutical Formulations.

Background: Propolis is a resinous material with complex chemical structure, produced by bees using plant sources, displaying a wide spectrum of biological activities.

Methods: Many studies have reported the use of this compound in pharmaceutical, medicinal, veterinary and dentistry areas, and the results have reported its pharmacological activities.

Results: Moreover, many propolis delivery systems have been proposed and evaluated, indicating that they can be used.

Neurosurgical implications of Pott's puffy tumor in children and adolescents.

Introduction: Pott's puffy tumor (PPT) is rare and usually seen as a complication of frontal sinusitis resulting in subperiosteal abscess of the frontal bone with underlying osteomyelitis. PPT is potentially severe and can lead to life-threatening intracranial complications.

Patients And Methods: The authors present a series of six pediatric patients diagnosed with PPT and intracranial complications between 1999 and 2012.

Patient selection and counseling before prostatic arterial embolization.

Prostatic arterial embolization (PAE) for relief of lower urinary tract symptoms (LUTS) in patients with prostate enlargement or benign prostatic hyperplasia (PE or BPH) is an experimental procedure with promising preliminary results. Patient evaluation and selection before PAE is paramount to improve technical and clinical results. Our inclusion criteria for PAE include: male patients, age>40 years, prostate volume>30 cm(3) and diagnosis of PE or BPH with moderate to severe LUTS refractory to medical treatment for at least 6 months (International Prostate Symptom Score [IPSS]>18, or quality of life [QoL]>3, or both) or with acute urinary retention refractory to medical therapy.
