Despite the lack of published data, COVID-19 vaccines can also be performed during chemotherapy by avoiding periods of bone marrow aplasia and if possible, to do it in cancer care centers. Ceralasertib It is necessary to implement cohorts with immunological and clinical monitoring of vaccinated cancer patients. To conclude, considering the current state of knowledge, the benefit-risk ratio strongly favours COVID-19 vaccination of all cancer patients.

A nonsynonymous single nucleotide polymorphism in the neuropeptide S receptor 1 (NPSR1) gene (rs324981) results in isoleucine-to-asparagine substitution at amino acid 107. link2 In humans, the ancestral variant (NPSR1 I107) is associated with increased anxiety sensitivity and risk of panic disorder, while the human-specific variant (NPSR1 N107) is considered protective against excessive anxiety. In rodents, neurobiological constituents of the NPS system have been analyzed in detail and their anxiolytic-like effects have been endorsed. However, their implication for anxiety and related disorders in humans remains unclear, as rodents carry only the ancestral NPSR1 I107 variant.

We hypothesized that phenotypic correlates of NPSR1 variants manifest in fear-related circuits in the amygdala. We used CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/Cas9)-mediated gene editing to generate a "humanized" mouse strain, in which individuals express either NPSR1 I107 or NPSR1 N107.

Stimulation of NPSin fear extinction and high anxiety sensitivity of individuals bearing the ancestral NPSR1 I107 variant.

Female sex is a known risk factor in most cardiac surgery, including coronary and valve surgery, but unknown in acute type A aortic dissection repair.

From 1996 to 2018, 650 patients underwent acute type A aortic dissection repair; 206 (32%) were female, and 444 (68%) were male. Data were collected through the Cardiac Surgery Data Warehouse, medical record review, and National Death Index database.

Compared with men, women were significantly older (65 vs 57years, P<.0001). The proportion of women and men inverted with increasing age, with 23% of patients aged less than 50years and 65% of patients aged 80years or older being female. Women had significantly less chronic renal failure (2.0% vs 5.4%, P=.04), acute myocardial infarction (1.0% vs 3.8%, P=.04), and severe aortic insufficiency. Women underwent significantly fewer aortic root replacements with similar aortic arch procedures, shorter cardiopulmonary bypass times (211 vs 229minutes, P=.0001), and aortic crossclamp times (132 vs 164minutes, P<.0001), but required more intraoperative blood transfusion (4 vs 3 units) compared with men. Women had significantly lower operative mortality (4.9% vs 9.5%, P=.04), especially in those aged more than 70years (4.4% vs 16%, P=.02). The significant risk factors for operative mortality were male sex (odds ratio, 2.2), chronic renal failure (odds ratio, 3.4), and cardiogenic shock (odds ratio, 6.8). The 10-year survival was similar between sexes.

Physicians and women should be cognizant of the risk of acute type A aortic dissection later in life in women. Surgeons should strongly consider operations for acute type A aortic dissection in women, especially in patients aged 70years or more.

A consolidated dMRI protocol for clinical applications that enables the mapping of tissue microstructural attributes is presented.Diffusion-weighted imaging (DWI) thermometry is a magnetic resonance-based imaging tool that allows the noninvasive measurement of brain core temperature. Although only applicable to cerebrospinal fluid, it is thought to be potentially useful in assessing the thermal pathophysiology of the brain in both patients and healthy subjects. The objective of this article is to provide a concise but thorough review of the basic physical principles and the principal applications of DWI thermometry as a potential method to elucidate the pathophysiology of several brain diseases and neurologic syndromes.The glymphatic system hypothesis is associated with the circulation of cerebrospinal fluid (CSF) in the skull and interstitial fluid (ISF) in the brain. There are several imaging techniques to visualize the dynamics of CSF and ISF. Magnetic resonance imaging (MRI) is one of the promising modalities for glymphatic imaging and diffusion MRI is expected imaging tool. Several disorders are associated with glymphatic dysfunction or impairment in the dynamics of CSF or ISF. The Central Nervous System interstitial fluidopathy concept has been proposed to encompass diseases with pathologies that are predominantly associated with abnormal ISF/CSF dynamics.The signal acquired in vivo using a diffusion-weighted MR imaging (DWI) sequence is influenced by blood motion in the tissue. This means that perfusion information from a DWI sequence can be obtained in addition to thermal diffusion, if the appropriate sequence parameters and postprocessing methods are applied. This is commonly regrouped under the denomination intravoxel incoherent motion (IVIM) perfusion MR imaging. Of relevance, the perfusion information acquired with IVIM is essentially local, quantitative and acquired without intravenous injection of contrast media. The aim of this work is to review the IVIM method and its clinical applications.Diffusion techniques provide valuable information when performing head and neck imaging. This information can be used to detect the presence or absence of pathology, refine differential diagnosis, determine the location for biopsy, assess response to treatment, and prognosticate outcomes. For example, when certain technical factors are taken into consideration, diffusion techniques prove indispensable in assessing for residual cholesteatoma following middle ear surgery. In other scenarios, pretreatment apparent diffusion coefficient values may assist in prognosticating outcomes in laryngeal cancer and likelihood of response to radiation therapy. As diffusion techniques continue to advance, so too will its clinical utility.Spinal cord often is regarded as one of the last territories in the central nervous system where diffusion tensor imaging (DTI) can be used to probe white matter architecture. This article reviews current progress in spinal cord DTI, starting with anatomic properties and technical challenges that make spinal cord DTI a difficult task. Several possibilities offered by advanced pulse sequences that might overcome the difficulties are addressed, with associated trade-offs and limitations. Potential clinical assistance also is discussed in various spinal cord pathologies, such as myelopathy due to external compression, spinal cord tumors, acute ischemia, traumatic injury, and so forth.Diffusion magnetic resonance imaging (MRI) offers a wealth of information regarding the neonatal brain. Diffusion anisotropy values reflect changes in the microstructure that accompany early maturation of white and gray matter. In term neonates with neonatal encephalopathy, diffusion imaging provides a useful means of assessing brain injury during the first week of life. In preterm neonates, measures of white matter anisotropy provide information on the nature and extent of white matter disruption. Subsequently, diffusion MRI plays an important role in illuminating fundamental elements of brain development and fulfilling the clinical need to develop prognostic indicators for term and preterm infants.This article reviews diseases for which persistent signal abnormalities on diffusion-weighted imaging are the key to their diagnosis. Specifically, updated knowledge regarding the neuroimaging patterns of the following diseases is summarized sporadic Creutzfeldt-Jakob disease, neuronal intranuclear inclusion disease, and hereditary diffuse leukoencephalopathy with axonal spheroids-colony-stimulating factor receptors/adult-onset leukoencephalopathy with axonal spheroids and pigmented glia. In addition, their differential diagnoses; clinical manifestations; and pathologic, genetic, and imaging correlates are discussed.Multiple pathologic conditions can cause changes in the random movement of water, which can be detected with diffusion-weighted imaging (DWI). DWI plays a powerful clinical role in detecting restricted diffusion associated with acute brain infarction. Other disorders can also result in restricted diffusion. This article focuses on showing examples of common and uncommon disorders that have restricted diffusion secondary to cytotoxic and/or intramyelinic edema. These disorders include ischemia, infection, noninfectious demyelinating diseases, genetic mutations affecting metabolism, acquired metabolic disorders, toxic or drug exposures, neoplasms and tumorlike lesions, radiation treatment, trauma, and denervation.Diffusion-weighted images provide a unique contrast that shows the ability to assess tissue structure and condition on a micrometer scale. Notably, these equations are necessary to understand diffusion MR imaging as a theory but not for real imaging, particularly in clinical practice. The diffusion phenomenon can be observed only through MR measurements. One of the emerging fields of diffusion MRI is to probe the tissue microstructure by altering the diffusion time t, the time interval over which spin displacements are sampled. However, the diffusion time is, in a sense, more important than the b-value for diffusion-weighted images and their quantitative metrics.

If exposure to childhood trauma increases the risk to later develop a psychotic disorder, the impact of such events on clinical presentation and outcome after a first psychotic episode deserves attention both in order to identify specific patients' needs and to develop adapted therapeutic interventions.

Three hundred and sixty-two patients treated at TIPP-Lausanne, a specialized program for the treatment of the early phase of psychotic disorders, were assessed prospectively, from baseline and every six months until the end of the 36months of treatment. We compared characteristics of patients exposed to childhood sexual and/or physical abuse to those of non-exposed patients.

One hundred and eight patients (29.8%) were exposed to at least one episode of physical and/or sexual abuse during childhood. Exposed patients displayed higher levels of positive and depressive symptoms and had lower levels of functioning throughout the entire three year follow-up period.

The prevalence of exposure to major traumatic events during childhood in early psychosis patients is very high, and it has an important impact on symptomatic and functional outcome. However, when clinical care is adapted, such patients seem to have a great potential for recovery. This justifies the implementation of specialized early psychosis programs and additional research in order to develop specific and adapted therapeutic strategies for such patients.
