There were significant, differences in vCD34 + recovery ( P < 0.01) after cryopreservation associated with, the fresh NCC of ≥ 300 × 10 /mL in products stored overnight, but no association, with time to platelet or neutrophil engraftment post-ASCT was observed for these, products.

Borylated 2,3,4,5-Tetrachlorophthalimide and Their 2,3,4,5-Tetrachlorobenzamide Analogues: Synthesis, Their Glycosidase Inhibition and Anticancer Properties in View to Boron Neutron Capture Therapy.

Tetrachlorinated phthalimide analogues bearing a boron-pinacolate ester group were synthesised via two synthetic routes and evaluated in their glycosidase modulating and anticancer properties, with a view to use them in boron neutron capture therapy (BNCT), a promising radiation type for cancer, as this therapy does little damage to biological tissue. An unexpected decarbonylation/decarboxylation to five 2,3,4,5-tetrachlorobenzamides was observed and confirmed by X-ray crystallography studies, thus, giving access to a family of borylated 2,3,4,5-tetrachlorobenzamides. Biological evaluation showed the benzamide drugs to possess good to weak potencies (74.

Circulating Tumor DNA Analysis Guiding Adjuvant Therapy in Stage II Colon Cancer.

Background: The role of adjuvant chemotherapy in stage II colon cancer continues to be debated. The presence of circulating tumor DNA (ctDNA) after surgery predicts very poor recurrence-free survival, whereas its absence predicts a low risk of recurrence. The benefit of adjuvant chemotherapy for ctDNA-positive patients is not well understood.

The importance of anthropology in psychiatry.

Anthropology is defined as "the study of humans", while psychiatric anthropology is a subfield of cultural anthropology which uses qualitative methodologies to explore the experience of mental illness. In a field that is often dominated by quantitative research, an anthropological approach allows us to understand experiences surrounding illness and the cultural context of mental illness. The articles presented in this issue of the Irish Journal of Psychological Medicine explore individual and group perspectives within a variety of cultural and historical contexts.

Role of stem cell transplant in CD30+ PTCL following frontline brentuximab vedotin plus CHP or CHOP in ECHELON-2.

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of aggressive non-Hodgkin lymphomas, the majority of which have high relapse rates following standard therapy. Despite use of consolidative stem cell transplant (SCT) following frontline therapy, there remains no consensus on its utility. The double-blind randomized phase 3 ECHELON-2 study (#NCT01777152; clinicaltrials.

Safety and efficacy of atezolizumab with obinutuzumab and bendamustine in previously untreated follicular lymphoma.

The ECHELON-2 Trial: 5-year results of a randomized, phase III study of brentuximab vedotin with chemotherapy for CD30-positive peripheral T-cell lymphoma.

Background: For patients with peripheral T-cell lymphoma (PTCL), outcomes using frontline treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapy are typically poor. The ECHELON-2 study demonstrated that brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP) exhibited statistically superior progression-free survival (PFS) per independent central review and improvements in overall survival versus CHOP for the frontline treatment of patients with systemic anaplastic large cell lymphoma or other CD30-positive PTCL.

Patients And Methods: ECHELON-2 is a double-blind, double-dummy, randomized, placebo-controlled, active-comparator phase III study.

The global impact on mental health almost 2 years into the COVID-19 pandemic.

Approaching 2 years into a global pandemic, it is timely to reflect on how COVID-19 has impacted the mental health of the global population. With research continuing apace, a clearer picture should crystallise in time. COVID-19 has undoubtedly had some impact on population mental health, although the severity and duration of this impact remain less clear.

Public mental health: a psychiatry and public health perspective.

Mental health issues are fast becoming one of society's greatest health challenges with evidence of higher levels of illness and strain on psychiatric services. The reasons for this trend of increasing mental health problems across the population are complex and there is an urgent need to research and deliver effective public mental health strategies. In this perspective piece we argue that psychiatrists and public health physicians have unique knowledge and perspectives on population mental health.

Risk-benefit analysis of the AstraZeneca COVID-19 vaccine in Australia using a Bayesian network modelling framework.

Thrombosis and Thrombocytopenia Syndrome (TTS) has been associated with the AstraZencea (AZ) COVID-19 vaccine (Vaxzevria). Australia has reported low TTS incidence of < 3/100,000 after the first dose, with case fatality rate (CFR) of 5-6%. Risk-benefit analysis of vaccination has been challenging because of rapidly evolving data, changing levels of transmission, and variation in rates of TTS, COVID-19, and CFR between age groups.
