Experiences of Mothers of Preterm Infants in the Neonatal Intensive Care Unit During the COVID-19 Pandemic.

Background: The neonatal intensive care unit (NICU) stay following the birth of a preterm infant can be stressful and traumatic for families. During the COVID-19 pandemic, the NICU environment changed precipitously as infection control and visitor restriction measures were implemented.

Purpose: Our study aimed to examine the impact of the pandemic policies on the experiences of mothers of preterm infants during their stay in the NICU.

COVID-19 Outbreak: Understanding Moral-Distress Experiences Faced by Healthcare Workers in British Columbia, Canada.

Pandemic-management plans shift the care model from patient-centred to public-centred and increase the risk of healthcare workers (HCWs) experiencing moral distress (MD). This study aimed to understand HCWs' MD experiences during the COVID-19 pandemic and to identify HCWs' preferred coping strategies. Based on a qualitative research methodology, three surveys were distributed at different stages of the pandemic response in British Columbia (BC), Canada.

Factors Associated with Umbilical Venous Catheter Malposition in Newborns: A Tertiary Center Experience.

Objective: Umbilical venous catheters (UVC) are widely used in neonatal intensive care (NICU). Noncentral catheter position is known to be associated with multiple adverse complications; however, risk factors for catheter malposition are unclear. This work aimed to identify clinical risk factors and complications associated with UVC malposition in neonates admitted in an NICU.

Whole blood genome-wide transcriptome profiling and metagenomics next-generation sequencing in young infants with suspected sepsis in a low-and middle-income country: A study protocol.

Conducting collaborative and comprehensive epidemiological research on neonatal sepsis in low- and middle-income countries (LMICs) is challenging due to a lack of diagnostic tests. This prospective study protocol aims to obtain epidemiological data on bacterial sepsis in newborns and young infants at Kamuzu Central Hospital in Lilongwe, Malawi. The main goal is to determine if the use of whole blood transcriptome host immune response signatures can help in the identification of infants who have sepsis of bacterial causes.

Use of Machine Learning for Predicting Escitalopram Treatment Outcome From Electroencephalography Recordings in Adult Patients With Depression.

Importance: Social and economic costs of depression are exacerbated by prolonged periods spent identifying treatments that would be effective for a particular patient. Thus, a tool that reliably predicts an individual patient's response to treatment could significantly reduce the burden of depression.

Objective: To estimate how accurately an outcome of escitalopram treatment can be predicted from electroencephalographic (EEG) data on patients with depression.

The brain frequency tuning function for facial emotion discrimination: An ssVEP study.

Steady-state visual evoked potentials have only been applied recently to the study of face perception. We used this method to study the spatial and temporal dynamics of expression perception in the human brain and test the prediction that, as in the case of identity perception, the optimal frequency for facial expression would also be in the range of 5-6 Hz. We presented facial expressions at different flickering frequencies (2-8 Hz) to human observers while recording their brain electrical activity.

Interactions between the perception of age and ethnicity in faces: an event-related potential study.

Face perception models propose that different facial attributes are processed by anatomically distinct neural pathways that partially overlap. Whether these attributes interact functionally is an open question. Our goal was to determine if there are interactions between age and ethnicity processing and, if so, at what temporal epoch these interactions are evident.

Temporal dynamics of the face familiarity effect: bootstrap analysis of single-subject event-related potential data.

Prior event-related potential studies using group statistics within a priori selected time windows have yielded conflicting results about familiarity effects in face processing. Our goal was to evaluate the temporal dynamics of the familiarity effect at all time points at the single-subject level. Ten subjects were shown faces of anonymous people or celebrities.

The 6 Hz fundamental stimulation frequency rate for individual face discrimination in the right occipito-temporal cortex.

What is the stimulus presentation rate at which the human brain can discriminate each exemplar of a familiar visual category? We presented faces at 14 frequency rates (1.0-16.66 Hz) to human observers while recording high-density electroencephalogram (EEG).

[Influence of levodopa on cognition of idiopathic Parkinson's disease].

Introduction: Idiopathic Parkinson's disease induces alterations both motor and cognitive. Levodopa, the treatment of choice, offers initial improvement, but causes long term important complications. It is ignored if it provokes or not a similar situation in cognitive function.

[Event-related potentials and the diagnosis of short-term verbal memory disorders in cerebrovascular disease].

Introduction: Cerebrovascular disease can cause different memory disorders depending on the area of the brain involved. More specifically, ischemic lesions in the frontal region can be associated to short-term verbal memory disorders.

Patients And Methods: Two groups of subjects were studied, 10 of whom were patients who presented a frontal cerebral infarction and 10 healthy controls.

[Cognitive diagnosis of cerebrovascular disease by event related potentials: anatomical sources that generate P300].

Introduction: Cerebrovascular disease causes different cognitive alterations. There is a need to develop tools that are capable of diagnosing them. One of them could be event related potentials.

[Specific alterations in attention in the early stages of Parkinson's disease].

Introduction: The cognitive disorders presented by patients with Parkinson s disease (PD) have drawn attention to the role played by the basal ganglia in cognition. It has been suggested that through a system of cortico subcortical circuits they monitor the work done by the frontal regions by guiding the anterior and posterior attentional systems, whose functioning is necessary for the so called executive functions to be carried out.

Patients And Methods: We studied 10 patients with PD in developmental stages I and II according to the scale of Hoehn and Yahr, and 10 healthy paired controls.

[Use of event related potentials for the diagnosis and follow up of sub clinical disorders of sustained attention in ischemic cerebrovascular disease].

Introduction: Ischemic cerebrovascular disease causes cognitive disorders among survivors, which may range from vascular dementia to alterations of a sub clinical nature. These are not easily detected using conventional diagnostic tools. Some of the most frequent disorders after a cerebral infarction are those affecting sustained attention or vigilance.

[Usefulness of P300 as a tool for diagnosing alterations in sustained attention in ischemic cerebrovascular disease].

Introduction: Event related potentials, and especially the component P300, can be used to achieve greater precision and sensitivity in the cognitive evaluation of patients. They also enable us to obtain more accurate information about deficiencies in sustained attention, which is a cognitive function associated with the generation of the above mentioned component. Furthermore, the study of disorders triggered off by cerebrovascular disease must be given priority because of the high incidence with which they occur.
