Sensory perception is profoundly shaped by attention. Attending to an odor strongly regulates if and how it is perceived - yet the brain systems involved in this process are unknown. Here we report integration of the medial prefrontal cortex (mPFC), a collection of brain regions integral to attention, with the olfactory system in the context of selective attention to odors.

First, we used tracing methods to establish the tubular striatum (TuS, also known as the olfactory tubercle) as the primary olfactory region to receive direct mPFC input in rats. Next, we recorded (i) local field potentials from the olfactory bulb (OB), mPFC, and TuS, or (ii) sniffing, while rats completed an olfactory selective attention task.

Gamma power and coupling of gamma oscillations with theta phase were consistently high as rats flexibly switched their attention to odors. Beta and theta synchrony between mPFC and olfactory regions were elevated as rats switched their attention to odors. Finally, we found that sniffing was consistent despite shifting attentional demands, suggesting that the mPFC-OB theta coherence is independent of changes in active sampling.

Together, these findings begin to define an olfactory attention network wherein mPFC activity, as well as that within olfactory regions, are coordinated based upon attentional states.

The study aims to investigate the prevalence of individuals with disabilities who reported using wearable devices, to examine the association between wearable device usage and disability status, and to determine the characteristic of individuals with disabilities associated with wearable device usage using the 2017 Behavioural Risk Factor Surveillance System (BRFSS) through secondary data analysis.

Data from the 2017 BRFSS of eight states were used in the analysis. Descriptive analysis, chi-square analysis, and multivariable logistic regressions were performed. Subsample analyses were also conducted for individuals with disabilities and different types of disability, including visual impairments, hearing impairments, cognitive disability, independent living disability, self-care disability, and mobility disability on wearable device usage.

14.6% (95% CI [11.7, 17.5]) of participants with disabilities were wearable device users. Individuals with disabilities were .63 (95% CI [.48, .83],

 < 0.001) anly to utilise wearable devices in free living setting.Further research is needed to determine the accessibility of wearable devices for individuals with disabilities and its usage in rehabilitation setting.A complete, objective and systematic documentation of delivery room resuscitation is important for research, for quality improvement, for teaching and as a reference for post resuscitation care. However, documentation during neonatal resuscitation is usually paper-based, retrospective, inaccurate and unreliable. In this narrative review, we discuss the strengths and pitfalls of current documentation methods in neonatal resuscitation, as well as the challenges of introducing new or emerging technologies in this field. In particular, we discuss innovations in electronic and automated medical records, video recording and Smartphones and Tablet Apps. Given the lack of a consensus standard, we finally propose a list of items that should be part of any neonatal resuscitation documentation method.

Repetitive and Stereotyped Behaviors (ST) are one of the key features of autism spectrum disorder (ASD) and they frequently occur in children with developmental delay/intellectual disability or sensory deprivation, but they are also described in children otherwise typical. This study aims to describe and compare ST in children with different neurodevelopmental disorders and in children having stereotypies but no other medical diagnosis (primary stereotypies).

The study sample comprised children with autism spectrum disorder (ASD) developmental delay (DD), severe visual impairment (VI) and primary stereotypies (PS), aged between 2 and 12 years old. The characteristics of the ST (age of onset, frequency, duration, triggers, phenomenology) were collected from their clinical history. The children's caregivers completed the Repetitive Behavior Scalerevised (RBS-R) and the Child Behavior Checklist (CBCL) to assess the ST and to screen for behavioral problems, respectively. Data concerning family history and comnificant overlap among different groups. These preliminary results suggest that stereotypies are strongly linked to neurodevelopmental disorders, but their association needs to be clarified with further studies.

The study showed that some specific patterns of stereotypies could be identified in most groups of disorders. At the same time the behavioral profile of children with stereotypies shows a significant overlap among different groups. These preliminary results suggest that stereotypies are strongly linked to neurodevelopmental disorders, but their association needs to be clarified with further studies.Multisystem inflammatory syndrome in children (MIS-C) associated with Severe Acute Respiratory Coronavirus 2 (SARS-CoV-2) usually develops 1-1.5 months after mild or asymptomatic COVID-19 in countries with high incidence. MIS-C has a polymorphism of clinical manifestations, which include prolonged fever, polymorphic rash, non-purulent conjunctivitis, pneumonia complicated by distress syndrome, myocarditis, coronary artery disease, toxic shock syndrome, limb edema, polyserositis, severe abdominal syndrome with diarrhea and others. Establishing this diagnosis requires significant efforts to rule out diseases of other etiology. The aim of our study was to analyze the clinical and laboratory features of children with MIS-C associated with SARS-CoV-2 and severe abdominal syndrome. Six children with MIS-C associated with SARS-CoV-2 and severe abdominal syndrome were hospitalized in Lviv Regional Children's Clinical Hospital "OHMATDYT", Ukraine, from April 2020 to September 2021. For differential diagnosis IgM, IgG to SARS-CoV-2 by ELISA, RNA to SARS-CoV-2 by PCR, bacteriological tests of blood, urine and feces were performed. Furthermore, the diagnostic work up included chest radiography, echocardiography, ultrasound of the lungs and abdominal organs. Laboratory findings revealed an increase in the normal value of inflammatory markers and high levels of IgG to SARS-CoV-2. Administration of intravenous immunoglobulin at a dose of 1 to 2 g/kg body weight per day prevented further coronary artery disease in patients and provided regression in already affected coronary arteries. At the same time, regression of abdominal syndrome was observed. Early diagnosis of MIS-C in patients with SARS-CoV-2 and severe abdominal syndrome allows to define the appropriate treatment strategy.For patients with optimally treated chronic myeloid leukemia (CML), discontinuation of tyrosine kinase inhibitor (TKI) therapy can lead to treatment-free remission. In previous trials, TKI discontinuation has been associated with increased musculoskeletal pain in some patients ("withdrawal syndrome"), based on physician-reported adverse events (AE). Patient-reported pain has not been described. The Life After Stopping TKI study was a 14-site prospective, non-randomized clinical trial of TKI discontinuation. We defined increased pain after discontinuation as (i) a physician-reported pain AE, (ii) a 2-level increase in self-reported musculoskeletal pain (4-level single item), or (iii) initiation of a medication for pain. We plotted the trajectory of patient-reported pain over time using a piecewise mixed-effects ordinal logistic model. Within 3 months of discontinuation, 35 of 172 patients (20.3%) had a physician-reported pain AE, 22 of 172 (12.8%) had an increase in self-reported pain, and 18 of 154 (11.7%) initiated a pain medication. Agreement among these measures was limited; overall, 60 of 172 patients (34.9%) had increased pain. Three patients (1.7%) restarted a TKI because of pain. The modelpredicted trajectory showed an increase in pain in the first 3 months followed by a decrease, returning to baseline levels by 6 months and further decreasing after that. This trajectory was similar among patients who did and did not restart TKI, suggesting that resuming a TKI for withdrawal syndrome may be necessary for some, but other approaches to manage pain should be tried so that patients can remain in treatment-free remission when possible.Retinal ganglion cells (RGCs) are the most important type of neurons in the visual pathway. RGC axons exit the eye to form the optic nerve, which connects with the brain. The visual signals carried by RGC axons establish the only link between the outside world and our internal perception of sight. Researches on the morphological, physiological, molecular, and mosaic features of RGCs are of great significance. This article reviews the research advances of RGC classifications, definitive types of RGCs, and selective vulnerability of specific RGC types after various injuries.Cataract is the leading cause of visual impairment and blindness on a global scale. The pathogenesis of cataract is not completely understood. Circular RNAs (circRNAs) are a special kind of non-coding RNAs with high stability and conservation. They are widely involved in a variety of biological processes and diseases. Abnormal expression of circRNAs can participate in the development of cataract, affecting the function of lens epithelial cells through interacting with proteins and sponging microRNAs. They are possible targets for cataract prevention and treatment. This article reviews the research progress on the role of circRNAs in the occurrence and development of cataract.A 65-year-old patient was admitted to the hospital due to proptosis of the left eye accompanied with ophthalmodynia and toothache for two months. Ophthalmic examination revealed a palpable mass around the lateral orbit and temporal fossa, and maxillofacial CT suggested a malignant tumor invading the left orbital floor wall. Chk2 Inhibitor II order One week later, the patient was diagnosed with left orbital cellulitis and septic shock due to peri-orbit redness, eyelid edema, chest tightness, nausea, vomiting, hypotension, and a marked increase in peripheral blood neutrophil count. The infection was well controlled after remission of shock, anti-infective therapy and surgical drainage. At 2 months after surgery, the surgical incision of the upper eyelid skin recovered well and the best corrected visual acuity of the left eye was 1.0.The proband was an 8-year-old boy, complaining of progressively decreased vision in both eyes for 3 years. The electroretinogram was characterized by supernormal rod response. While the responses of the rod and cone system were reduced, the amplitudes of dark-adapted electroretinogram responses at a high intensity were supernormal. A homozygous non-frameshift deletion variant c.1002-1004del (p. L335del) in KCNV2 was found by the Next Generation Sequencing using a custom designed panel. His father was a heterozygous carrier of this variant. In silico analysis indicated the variant was harmful. The proband was diagnosed as cone dystrophy type 3B which also known as cone dystrophy with supernormal rod response.
