Clinical and epidemiological features of mpox in a Brazilian reference center for HIV and sexually transmitted infections: A cross-sectional study.

Background: The 2022 mpox outbreak has affected disproportionately people living with HIV (PLWH) and pre-exposure prophylaxis (PrEP) users.

Methods: We conducted a cross-sectional study to evaluate factors associated with laboratory diagnosis of mpox among suspected cases, and access differences between PrEP users and PLWH with confirmed diagnostic.

Results: 394 mpox suspected cases were analyzed, 309 (78.

Three cases of oral mucosal tuberculosis in patients on tumour-necrosis-factor-α blockers.

We present three cases of oral mucosal lesions caused by Mycobacterium tuberculosis in patients treated with anti-tumour necrosis factor-α for psoriasis or rheumatoid arthritis. Diagnosis of oral mucosal tuberculosis was not easily established in any of the cases. A comparison between these cases and other previously described forms of oral mucosal tuberculosis is presented.

Detection of intention of pedaling start cycle through EEG signals.

Recovery from cerebrovascular accident (CVA) is a growing research topic. Exoskeletons are being used for this purpose in combination with a volitional control algorithm. This work studied the intention of pedaling initiation movement, based on previous work, with different types of electrode configuration and different processing time windows.

Nitric oxide triggers a transient metabolic reprogramming in Arabidopsis.

Nitric oxide (NO) regulates plant growth and development as well as responses to stress that enhanced its endogenous production. Arabidopsis plants exposed to a pulse of exogenous NO gas were used for untargeted global metabolomic analyses thus allowing the identification of metabolic processes affected by NO. At early time points after treatment, NO scavenged superoxide anion and induced the nitration and the S-nitrosylation of proteins.

Decoding the Attentional Demands of Gait through EEG Gamma Band Features.

Rehabilitation techniques are evolving focused on improving their performance in terms of duration and level of recovery. Current studies encourage the patient's involvement in their rehabilitation. Brain-Computer Interfaces are capable of decoding the cognitive state of users to provide feedback to an external device.

Characterization of Artifacts Produced by Gel Displacement on Non-invasive Brain-Machine Interfaces during Ambulation.

So far, Brain-Machine Interfaces (BMIs) have been mainly used to study brain potentials during movement-free conditions. Recently, due to the emerging concern of improving rehabilitation therapies, these systems are also being used during gait experiments. Under this new condition, the evaluation of motion artifacts has become a critical point to assure the validity of the results obtained.

A supplementary system for a brain-machine interface based on jaw artifacts for the bidimensional control of a robotic arm.

Non-invasive Brain-Machine Interfaces (BMIs) are being used more and more these days to design systems focused on helping people with motor disabilities. Spontaneous BMIs translate user's brain signals into commands to control devices. On these systems, by and large, 2 different mental tasks can be detected with enough accuracy.

Evaluating classifiers to detect arm movement intention from EEG signals.

This paper presents a methodology to detect the intention to make a reaching movement with the arm in healthy subjects before the movement actually starts. This is done by measuring brain activity through electroencephalographic (EEG) signals that are registered by electrodes placed over the scalp. The preparation and performance of an arm movement generate a phenomenon called event-related desynchronization (ERD) in the mu and beta frequency bands.

First report of canine ocular thelaziosis by Thelazia callipaeda in Portugal.

Background: Thelazia callipaeda eyeworms are transmitted by the non-biting insect vector Phortica variegata in Europe and infest the conjunctiva(s) of several mammalians, including dogs and humans. Infested hosts might remain asymptomatic or display clinical manifestations characterized by variable degrees of severity.

Methods: From July to November 2011, nine dogs were detected with eyeworms at two veterinary clinics in Chaves and Bragança (North of Portugal).

Canine babesiosis in northern Portugal and molecular characterization of vector-borne co-infections.

Background: Protozoa and bacteria transmitted by arthropods, including ticks and phlebotomine sand flies, may cause a wide range of canine vector-borne diseases. Dogs can be simultaneously or sequentially infected with multiple pathogens. Canine babesiosis caused by Babesia canis canis and Babesia canis vogeli is known to occur in Portugal.

Babesia canis canis and Babesia canis vogeli infections in dogs from northern Portugal.

Canine babesiosis represents an important veterinary medical problem. This study describes the molecular characterization of babesial parasites detected in eight clinically suspected dogs from northern Portugal, affected by lethargy, muscle tremors, weight loss, pale mucous membranes, hyperthermia or red-coloured urine. Microscopic examination of peripheral blood smears showed large intraerythrocytic piroplasms morphologically compatible with Babesia canis in all eight animals.
