Introduction: Systemic lupus erythematosus is a rare disease; however, it is one of the leading causes of death in young women, in particular those with a larger percentage of Amerindian ancestry.

Areas Covered: This article provides a review of the epidemiology of systemic lupus erythematosus and lupus nephritis in the Latin American population, as well as the challenges for the appropriate management of these patients, including delays in diagnosis, healthcare access, and access to new drugs in the region. We propose potential solutions to these problems, including activities to be done by governments, healthcare systems, and healthcare professionals.

A generative adversarial network (GAN) makes it possible to map a data sample from one domain to another one. It has extensively been employed in image-to-image and text-to image translation. We propose an EEG-to-EEG translation model to map the scalp-mounted EEG (scEEG) sensor signals to intracranial EEG (iEEG) sensor signals recorded by foramen ovale sensors inserted into the brain.

In subjects implanted with intracranial electrodes, we use two different stories involving the same person (or place) to evaluate whether and to what extent context modulates human single-neuron responses. Nearly all neurons (97% during encoding and 100% during recall) initially responding to a person/place do not modulate their response with context. Likewise, nearly none (<1%) of the initially non-responsive neurons show conjunctive coding, responding to particular persons/places in a particular context during the tasks.

Article Synopsis
  • Epilepsia Partialis Continua (EPC) is a complex condition that may respond to repetitive transcranial magnetic stimulation (rTMS), which offers both diagnostic and therapeutic potential.
  • A review of literature involving cases of EPC treated with rTMS, alongside two in-house patient cases, highlights the varying efficacy of rTMS in reducing seizure activity.
  • Results indicate that while some patients experienced no change, low frequency rTMS led to temporary improvements in seizure frequency and motor function in two patients, suggesting its possible role in guiding further treatment.

Objective: To examine the predictors of the occurrence of severe thrombocytopenia and its impact on damage accrual and mortality in SLE patients.

Methods: Factors associated with time to severe thrombocytopenia (platelet count ≤20,000/mm) occurring from the onset of SLE symptoms were assessed by Cox proportional hazards regressions. The association of severe thrombocytopenia with mortality was evaluated by logistic regression analyses while its impact on damage was by negative binomial regression.

The purpose of the current paper is to explore the influence of the perceived trustworthiness factors of ability, benevolence and integrity on general and specific trust across supervisors, subordinates and peers with the same focal referent. This study used a 360-degree approach to examine how positional power asymmetries influence the relationship between trustworthiness and trust for a general and situation-specific referent. Data were obtained from military supervisors ( = 200), peers ( = 123), and subordinates ( = 85).

Identification of seizure sources in the brain is of paramount importance, particularly for drug-resistant epilepsy patients who may require surgical operation. Interictal epileptiform discharges (IEDs), which may or may not be frequent, are known to originate from seizure networks. Delayed responses (DRs) to brain electrical stimulation have been recently discovered.

Article Synopsis
  • Cranial neuropathies (CN) are a rare manifestation of neuropsychiatric lupus, and the study investigates the association of anti-KIF20B antibodies as a possible biomarker for this condition within a large cohort of SLE patients.
  • The research involved 795 patients from a larger cohort, revealing that 29.8% were positive for anti-KIF20B, with a significantly higher positivity rate (70%) in those with CN compared to those without (29.3%).
  • Findings suggest that anti-KIF20B positivity is linked to CN in SLE patients, indicating its potential as a biomarker, though further research is required to confirm these results.
