However, after ketamine injection, temporal expectation was significantly reduced in both subjects. In addition, ketamine also increased average movement latency but this effect could be dissociated from the reduction of temporal expectation.

In conclusion, a subanesthetic dose of ketamine could have two independent effects increasing reaction time and decreasing temporal expectation. This alteration of temporal expectation could explain cognitive deficits observed during ketamine use.

They can virtually originate in every organ of the human body and their classification is not uniform among different sites. Indeed, as they have historically been classified according to the organ in which they primarily arise, the different nomenclature that has resulted have created some confusion among pathologists and clinicians. Although a uniform terminology to classify neuroendocrine neoplasms arising in different systems has recently been proposed by WHO/IARC, some issues remain unsolved or need to be clarified. In this review, we discuss the lights and shadows of the current WHO classifications used to define and characterize NENs of the pituitary gland, lung, breast and those of the head and neck region, and digestive and urogenital systems.Although the overall clinical outcome of patients with diffuse large B cell lymphoma (DLBCL) has significantly improved, some patients still experience relapsed/refractory disease. In the rituximab era, real-world data about relapsed/refractory DLBCL are limited. To clarify the clinical outcome and prognostic factors in these patients, we conducted a retrospective analysis using data from the population-based Osaka Cancer Registry (OCR) from 2010 to 2015. In total, 189 adult patients aged up to 70 years who received CHOP or a CHOP-like regimen in combination with rituximab, as well as a subsequent second-line therapy, were included in the analysis. The median age was 63 years (range, 24-70). read more Age (> 63 years), the duration of first progression-free survival (PFS), and the use of rituximab in the second-line chemotherapy were prognostic factors for overall survival (OS) after the second-line treatment. In this cohort, 48 and 11 patients received autologous and allogeneic hematopoietic stem cell transplantation (HSCT), respectively. The probabilities of 3-year OS after autologous and allogeneic HSCT were 55.7% and 18.2%, respectively. In conclusion, we found that the clinical outcome of patients with relapsed/refractory DLBCL in the rituximab era was unsatisfactory. Further improvements in treatment strategies, including novel agents, are needed.Heart failure (HF) has an estimated prevalence of 1-2% in the world's population and up to 10% of patients age 65 and above. Iron deficiency (ID) in HF has been shown to be an independent contributor of increased mortality and poorer quality of life and has been associated with increased rates of hospitalization. Estimates are varied, but it is believed that as many as 30-83% of HF patients have ID, often without overt anemia, therefore making diagnosis more difficult. Well-established large studies have shown intravenous iron (IVFe) supplementation in HF patients is superior to an oral route, though these guidelines were developed for the chronic HF patients in the outpatient setting. For patients who are frequently hospitalized for HF, their inpatient stays may present an opportunity to diagnose ID. We previously showed that ID is underdiagnosed in the inpatient setting. To date, limited studies investigate long-term outcomes in hospitalized HF patients diagnosed with ID who are treated with IVFe compared to those who are not. In this retrospective analysis, we assessed 1-year readmission rates and mortality outcomes in patients who were diagnosed with ID while admitted for HF and subsequently received IVFe versus those who did not on their initial admission. These data suggest that there is no significant reduction in readmissions for HF or mortality between those patients who received IVFe and those who did not.Chronic diffuse parenchymal lung disease (DPLD) is an umbrella term for a very heterogeneous group of lung diseases. Over the last decades, clinical, radiological and histopathological criteria have been established to define and separate these entities. More recently the clinical utility of this approach has been challenged as a unifying concept of pathophysiological mechanisms and a shared response to therapy across the disease spectrum have been described. In this review, we discuss molecular motifs for subtyping and the prediction of prognosis focusing on genetics and markers found in the blood, lavage and tissue. As a purely molecular classification so far lacks sufficient sensitivity and specificity for subtyping, it is not routinely used and not implemented in international guidelines. However, a better molecular characterization of lung disease with a more precise identification of patients with, for example, a risk for rapid disease progression would facilitate more accurate treatment decisions and hopefully contribute to better patients' outcomes.Plasma cell differentiation (PCD) is frequently observed in some entities of non-Hodgkin B cell lymphoma, including both low-grade and high-grade lymphomas. However, except for plasmablastic lymphoma and primary effusion lymphoma, EBV+ B cell lymphoproliferative disorder (LPD) with PCD has not been well addressed due to its rarity. We clinicopathologically examined five cases of nodal EBV+ polymorphic B cell LPD with PCD (PBLPD-PCD) initially diagnosed as polymorphic EBV+ diffuse large B cell lymphoma, not otherwise specified (DLBCL-NOS) with PCD (n = 3) and methotrexate-associated B cell LPD (MTX-associated B-LPD) (n = 2). One case had a concomitant brain lesion which was clinically diagnosed as EBV-related encephalitis. This patient received therapy with vidarabine, and both the brain lesion and the nodal EBV+ PBLPD-PCD lesions disappeared. Another case was characterized by Mott cell differentiation. This case was the first reported case of EBV+ B cell lymphoma or LPD with Mott cell differentiation. The two cases of MTX-associated B cell LPD which arose in patients with rheumatoid arthritis spontaneously regressed after MTX cessation.
