Carboplatin hypersensitivity reactions have been reported to occur in up to 16% of patients with gynecologic cancers. Several predisposing factors have been suggested including presence of BRCA1/2 mutation, however, contribution of these mutations to reaction development has not been extensively studied. The purpose of this study was to determine if there is an association between BRCA1/2 mutation status and the development of carboplatin hypersensitivity reactions.

Eligible patients were women aged 18 years or older with a diagnosis of ovarian, fallopian tube, uterine, endometrial, or primary peritoneal cancer who attempted to receive at least one dose of carboplatin. The primary outcome was the effect of BRCA1/2 status on the development of carboplatin hypersensitivity reactions with regard to reaction frequency, timing, and severity. Secondary outcomes included identification of additional risk factors that may help identify predisposition to carboplatin hypersensitivity reaction.

A total of 44 patients were included in this study. Five patients (38%) in the reaction group and 4 patients (31%) in the no reaction group had a documented mutation in one or both BRCA genes (p = 1.00). No significant differences were found in terms of reaction severity or symptoms, and timing of reaction after dose administration. Incidence of thyroid disorder was significantly higher among patients who experienced a hypersensitivity reaction (1 (4%) vs 10 (45%); p = 0.004).

BRCA mutation status was not associated with an increased risk of carboplatin hypersensitivity in our patient population. LY3537982 in vivo Further investigation into thyroid dysfunction as a risk factor for reaction development is warranted.

Brentuximab vedotin (Bv) has been approved for the treatment of Refractory/Relapsed (R/R) Anaplastic Large Cell Lymphomas (ALCL) and cutaneous T-Cell Lymphomas, but is also effective in other CD30+ malignancies. We report here the outcomes of patients with various R/R Peripheral T Cell Lymphoma (PTCL) treated with Bv in real life practice.

This was a retrospective, single-center study based on medical records of patients with R/R PTCL treated either with Bv alone or in combination with chemotherapy.

Among 27 patients treated with Bv, neutropenia was the main serious adverse event observed in particular when Bv was used as combination treatment. The complete Response Rates (CRR) was 40.7%; it was significantly improved when Bv was used as combination treatment. The majority of eligible patients (7/10) underwent Stem Cell Transplantation. Median Progression Free Survival (PFS) and Overall Survival (OS) were 5.2 months and 12.5 months respectively.

Our current study shows that Bv used in combination with chemotherapy provides a high CRR and thereby allows SCT in R/R PTCL. The use of Bv treatments in this setting warrants further investigation.

At postmortem examination, no significant gross lesions were present. Histologic evaluation demonstrated nonsuppurative encephalitis in thalamus, brainstem, and hippocampus, cerebellar Purkinje cell loss, as well as poliomyelitis and demyelination of the spinal cord. Parvovirus antigen-specific immunohistochemistry revealed immunopositive neurons in the brainstem, cerebral cortex, and hippocampus. A few Purkinje cells were also immunopositive. DNA extracted from formalin-fixed, paraffin-embedded brain tissue (thalamus, hippocampus, cerebral cortex) yielded a positive signal using PCR targeting both feline and canine parvovirus. Sequencing analyses from a fragment of the NS1 gene and a portion of the VP2 gene confirmed the presence of DNA of a recent canine parvovirus variant (CPV-2a-like virus) in the cerebellum. Our case provides evidence that a recent canine parvovirus (CPV) strain (Carnivore protoparvovirus 1) can infect cerebral and diencephalic neurons and cause encephalitis in an otherwise healthy raccoon. Parvovirus-induced encephalitis is a differential diagnosis of rabies and canine distemper in raccoons with neurologic signs.The circadian clock is a universal timing system that involved in plant physical responses to abiotic stresses. Moreover, OSCA1 is an osmosensor responsible for [Ca2+]i increases induced by osmotic stress in plants. However, there is little information on osmosensor involved osmotic stress-triggered circadian clock responses. Using an aequorin-based Ca2+ imaging assay, we found the gradient (0 mM, 200 mM, 500 mM) osmotic stress (induced by sorbitol) both altered the primary circadian parameter of WT and osca1 mutant. This means the plant switch to a fast day/night model to avoid energy consumption. In contrast, the period of WT and osca1 mutant became short since the sorbitol concentration increased from 0 mM to 500 mM. As the sorbitol concentration increased, the phase of the WT becomes more extensive compared with osca1 mutant, which means WT is more capable of coping with the environmental change. Moreover, the amplitude of WT also becomes broader than osca1 mutant, especially in high (500 mM) sorbitol concentration, indicate the WT shows more responses in high osmotic stress. In a word, the WT has much more flexibility to cope with the osmotic stress than osca1 mutant. It implies the OSCA1 might be involved in the circadian gated plant adaptation to the environmental osmotic stress, which opens an avenue to study Ca2+ processes with other circadian signaling pathways.The purpose of the study was to psychometrically characterize the Ethical Leadership Scale (ELS) through confirmatory factor analysis (CFA) and Rasch analysis. Data were collected from 469 teachers across several countries. The one-factor structure of the ELS was confirmed in CFA. Rating scale diagnosis, item fit assessment, reliability analysis, unidimensionality, local independence, and differential item functioning (DIF) analyses were conducted using the Rasch Rating Scale Model. Item and rating scale analyses indicated that the ten items and five-category scale performed as intended. High person separation and reliability statistics supported the consistency of the ELS scores. Only one item (Item 4) demonstrated misfit in the Rasch model and two items (i.e., Items 2 and 10) showed DIF across Turkish and European respondents. None of the items showed DIF across gender. Overall CFA and Rasch models provided evidence for the psychometric quality of the 10-item ELS. However, reassessment of the scale after removing Item 4 showed improvement in the psychometric properties of the scale.
