Dispositional optimism is robustly associated with psychological wellbeing, and individuals with lower optimism tend to experience more depressive and anxiety symptoms. While mechanisms in this relationship such as coping and social integration have been explored, limited research has examined whether the self-conscious emotions of shame and guilt account for the association between dispositional optimism and psychological distress. The present study examined shame and guilt as mediators in the relation between dispositional optimism and depressive and anxiety symptom severity among 137 patients (M age = 33.5, SD = 12.08 years) seeking community-based mental health care. Mediation analyses using bootstrap 99% confidence intervals indicated significant mediation by guilt--but not shame--in the model predicting depressive symptoms, and significant mediation by shame--but not guilt--in the model predicting anxiety symptoms. These findings suggest differential effects of dispositional optimism on depressive and anxiety symptoms according to the predominance of shame- or guilt-related affects. Interventions seeking to reduce distress through promoting optimism may be enhanced by considering patients' experiences of shame and guilt.

Chromosomal instability (CIN) is a defining characteristic of cancer and is part of the genetic instability of cancer. CIN results in both numeric alterations of chromosomes also called aneuploidy and in gains or losses of parts of chromosome arms but both usually coexist. The frequency and distribution of CIN varies between cancer types and even in the same cancer and breast cancer is no exception. Its presence may provide prognostic and therapeutic opportunities.

CIN as measured with a score named Aneuploidy Score (AS) derived from single nucleotide polymorphism array studies was examined using the breast cancer study from the Cancer Genome Atlas (TCGA). learn more Correlations of the AS with sub-types of breast cancer and with the tumor mutation burden (TMB) were examined. Specific copy number alterations contributing to the AS and their associations with sub-types were also investigated.

Most breast cancers (about 75% in the series) present some degree of CIN, having an AS of above 5. The remaining 25% have AS-type and may help further characterize these sub-types in order to refine classification of these cancers and promote prognostic and therapeutic advancements in the clinic.Introduction Total lung-cancer-management costs are increasing dramatically. The widespread use of immune-checkpoint inhibitors (ICIs) explains this rise in large part and financially impacts healthcare systems. Economic assessment has been adapted to this new challenge. Areas covered This review provides an overview of the economic literature on the use of ICIs to treat lung cancer. Numerous papers have been published over the last few years. Cancers analyzed were non-squamous non-small-cell lung cancer (NSCLC), squamous NSCLC, locally advanced NSCLC, or small-cell lung cancer. Expert commentary For the majority of patients, ICIs are cost-effective for lung cancer management. However, these results are influenced by the threshold chosen by each of the different countries. Patient selection, treatment duration, and factors predictive of efficacy are mandatory to decrease costs.Electrochemotherapy (ECT) is a new and promising treatment strategy for cancer treatment. The aim of this work is to investigate the effect of 900 MHz radiofrequency electromagnetic fields (RF-EMFs) on the mechanisms of ECT (low voltage, high frequency) including cell permeability in vitro, and tumor hypoxia, immune system response in vivo, and on volume of tumors treated with ECT (70 V/cm, 5 kHz). The 4T1 cells were exposed to RF-EMFs at 17, 162, or 349 µW/cm2 power densities, using GSM900 simulator, 10 min. The cells were then put in individual groups, comprising of no treatment, chemotherapy, electric pulses (EPs), or ECT. The cell viability was evaluated. The mice with 4T1 tumor cells were exposed to RF field 10 min/day until the tumor volume reached about 8 mm. Then, the mice tumors were treated with ECT. Tumor hypoxia and immune system response was analyzed through immunohistochemistry (IHC) assay and ELISA technique, respectively. The volume of tumors was also calculated for 24 days following the treatment. The results showed that RF fields at 349 µW/cm2 could increase tumor hypoxia induced by ECT and cause a significant increase of Interferon-gamma (IFN-γ) in comparison with group ECT alone. However, 900 MHz radiations did not affect the volume of tumors treated to ECT (70 V/cm, 5 kHz) significantly. In this study, 900 MHz EMF could improve some biological pathways induced by ECT. Such a positive effect could utilize in some other treatments to increase efficacy, which should be investigated in further research.

In December 2019, the first COVID-19 case, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was reported in Wuhan, China. The SARS-CoV-2 rapidly disseminated throughout the world

community spread, acquiring pandemic status with significant fatality.

Rapid SARS-CoV-2 diagnosis was soon perceived critical for arresting community spread and effective therapy development. Human SARS-CoV-2 infection can be diagnosed either by nucleic acid identification or specific antibody detection. Contrary to nucleic acid identification confirmed active SARS-CoV-2 infection; antibody detection confirms a past infection, even in asymptomatic subjects. SARS-CoV-2 specific antibodies augment the ability to effectively counter the virus. A crucial hurdle limiting the steadfast implementation of antibody detection is the time required for threshold B lymphocyte population generation. This process is dependent on precise antigen recognition and MHC class I molecules presentation.

Thus, nucleic acid andection. While nucleic acid identification screens prevailing SARS-CoV-2 infection, detection of SARS-CoV-2 specific antibodies signifies a past infection, even in asymptomatic subjects. Antibodies against SARS-CoV-2 provide a potential therapeutic option via transfer from antibody rich plasma of a recovered subject to an infected individual. Nucleic acid identification may not absolutely confirm the infection because of frequent SARS-CoV-2 genome mutations and possible technical errors, while specific antibody detection also needs at least (8-14) days for detectable screening of B-cell generated antibodies. Nucleic acid and antibody tests are complementary to each other as an early stage diagnostic assay for SARS-CoV-2 infection and possible therapy (antibodies). Sufferers with a high clinical suspicion but negative RT-PCR screening could be examined via combined imaging and repeated swab test.
