Arcuate anterior jugular vein: a rare case report and its clinical relevance.

Objective: The present study describes a rare anatomical variation of the anterior jugular vein (AJV) and discusses its clinical relevance.

Methods: A head and neck specimen fixed in 10% formaldehyde from a 42-year-old female cadaver was submitted to angio technique with pre-vulcanized latex and water-soluble ink. During a routine dissection for the discipline of topographic anatomy, the presence of an arcuate AJV was detected in the anterior triangle of the neck.

Effect of the Basilar Invagination (Type B) on Cervical Spine: A Case-control Study with MRI.

Objective: To evaluate the effect of the basilar invagination (BI) type B on cervical spine.

Methods: The research protocol used head magnetic resonance imaging (MRI) exams from 41 participants with BI type B and 158 controls. The criterion for BI was the distance of the odontoid apex to Chamberlain's line (DOCL) equal to or greater than 7 mm.

Assessment of cognitive function in elderly patients with heart failure.

Objective: To compare the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) tests for the identification of cognitive deficit (CD) in elderly patients with heart failure (HF).

Methods: This was a cross-sectional study with an observational design involving 43 elderly patients with HF of both sexes, treated by the Unified Health System, who were able to understand and follow the study instructions. A sociodemographic and clinical questionnaire and the MMSE and MoCA neurocognitive tests were applied.

Complexed amino acid minerals vs. bis-glycinate chelated minerals: Impact on the performance of old laying hens.

The present study was to evaluate the effect of trace minerals (Zn, Mn, and Cu) from complexed amino acid minerals (ZMCAA) and bis-glycinate chelated minerals (ZMCGly) in laying hen diets on performance, internal and external egg quality, yolk mineral deposition, intestinal morphometry, and bone characteristics. From 78 to 98 weeks of age, 400 White LSL-Lite strain laying hens were distributed in a randomized design with 4 treatments with 10 replicates per treatment. Treatments were distributed in a 2 × 2 factorial arrangement using either Zn, Mn, and Cu of ZMCAA or ZMCGly source at 2 levels: low (20, 20, and 3.

Radioanalytical models applied to the investigation of caesium signatures in sugar samples.

The presence of anthropogenic radioisotopes in the environment may be due to inappropriate discards, nuclear tests and accidents, which requires and justifies constant monitoring to ensure the safety of nuclear applications. The radiometric analysis is a necessary condition for exporting sugar for world consumption. The investigation of Cs and Cs in a sugar matrix is required to predict radiometric anomalies.

Development of an Efficiency Platform Based on MQTT for UAV Controlling and DoS Attack Detection.

Several market sectors are attracted by the potential of unmanned aerial vehicles (UAVs), such as delivery, agriculture, and cinema, among others. UAVs are becoming part of Internet of Things (IoT) networks in the development of autonomous and scalable solutions. However, these vehicles are gradually becoming attractive targets for cyberattacks.

Investigating Type B Basilar Invagination Through Cephalic Indices.

Objective: We sought to compare the diagnostic accuracy of cephalic indices for type B basilar invagination (BI).

Methods: This retrospective study examined head and neck magnetic resonance imaging sequences of 31 Group B BI cases and 96 controls. Two examiners blinded to diagnostic data evaluated the cephalic indices of each magnetic resonance imaging sequence, described as width/length (WLI) and height/width (HWI).

Foramen Magnum Angle: A New Parameter for Basilar Invagination of Type B.

Objective: To describe the foramen magnum angle (FMA) as a new parameter for basilar invagination (BI) type B.

Methods: The FMA was performed on sagittal slice of magnetic resonance imaging (MRI) as a line from the hard palate to the opisthion (angle vertex), and another line from the opisthion to the basion. The MRIs from 31 participants with BI type B and 96 controls were used.

Assessment of costs related to cancer treatment.

Introduction: Cancer patients and their caregivers incur costs not covered by the Sistema Único de Saúde - SUS(Unified Health System) during their treatment, with expenses related to transportation, symptomatic medications, food, loss of working days, and others.

Objective: To evaluate the costs incurred and not covered for cancer patients and their caregivers during cancer treatment at SUS.

Methods: This is a cross-sectional study of 110 cancer patients undergoing chemotherapy, radiotherapy, and 88 caregivers in the last month prior to their inclusion in the study.

Localizing the Primary Motor Cortex of the Hand by the 10-5 and 10-20 Systems for Neurostimulation: An MRI Study.

. The primary motor cortex of the hand (M1-Hand) is a target used in transcranial magnetic stimulation (TMS) and in transcranial direct current stimulation (tDCS) for the treatment and evaluation of motor neurological diseases. Magnetic resonance imaging-guided neuronavigation locates the M1-Hand with high precision, but at a high cost.

Prediction of drug dissolution profiles from tablets using NIR diffuse reflectance spectroscopy: a rapid and nondestructive method.

A comparison between dissolution profiles obtained by using a dissolution apparatus (conventional method) and the NIR diffuse reflectance spectra of a series of clonazepam-containing batches is reported. Ten different formulations with fixed amount of clonazepam and varying proportions of excipients were analyzed at seven dissolution times and three different media. The percentages of dissolution of each sample were correlated with the NIR spectra of three tablets of each batch, through a multivariate analysis using the PLS regression algorithm.
