Age-related variations in gene expression patterns of renal cell carcinoma

Background

Clear cell renal cell carcinoma (ccRCC) is known to occur across the adult lifetime traversing the spectrum of age-related organismal changes. Little is known as to how the aging process may affect the course of renal cell carcinoma (RCC) and the repertoire of genes involved.

Nanoparticle albumin bound-paclitaxel for treatment of advanced non-small cell lung cancer: an evaluation of the clinical evidence

Introduction: Nanoparticle albumin-bound paclitaxel (nab-paclitaxel), a microtubule inhibitor, has demonstrated clinical efficacy in the treatment of advanced non-small cell lung cancer (NSCLC) either as monotherapy or in combination. Nab-paclitaxel was developed to reduce the toxicities associated with solvent-bound paclitaxel (sb-paclitaxel).

Areas covered: This review first focuses on the clinical trials evaluating the efficacy and tolerability of nab-paclitaxel in NSCLC at different settings. The approval of nab-paclitaxel in combination with carboplatin at the front-line setting for advanced NSCLC was based on the key phase III study, which showed that nab-paclitaxel/carboplatin was associated with superior overall response rate and favorable toxicity profile compared to sb-paclitaxel/carboplatin. The review also addresses the nab-paclitaxel pharmacology, other combinations (e.g. immunotherapy with PD-1/PD-L1 inhibitors), potential biomarkers (e.g. caveolin-1), and special subgroups (e.g. the elderly, squamous histology).

Expert opinion: Existing data has established the role of nab-paclitaxel in the management of advanced NSCLC. Emerging evidence, such as preliminary results from Keynote-407 and IMpower 131 studies, indicates that novel combinations of nab-paclitaxel/carboplatin and PD-1/PD-L1 inhibitors could further improve clinical benefits with manageable toxicity. Nevertheless, in order to better position nab-paclitaxel and to improve patient selection, future studies are warranted to further understand its mechanism of action, predictive biomarkers, and potential synergism with other agents.     

The relationships among monocyte subsets,miRNAs and inflammatory cytokines in patients with acute myocardial infarction

Background

Acute myocardial infarction (AMI) causes irreversible myocardial damage and release of inflammatory mediators, including cytokines, chemokines and miRNAs. We aimed to investigate changes in the levels of cytokines (IL-6, TNF-α and IL-10), miRNAs profiles (miR-146 and miR-155) and distribution of different monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) in the acute and post-healing phases of AMI.

Attenuated Novel SARS Coronavirus 2 Infection in an Allogeneic Hematopoietic Stem Cell Transplant Patient on Ruxolitinib

Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) has a high death rate in patients with comorbidities or in an immunocompromised state. We report a mild and attenuated SARS CoV-2 infection in a patient who is 17 months post stem cell transplantation and maintained on the JAK/STAT inhibitor ruxolitinib, a proposed novel therapy for SARS CoV-2 pneumonia.     

Functional beta-cells derived from umbilical cord blood mesenchymal stem cells for curing rats with streptozotocin-induced diabetes mellitus

INTRODUCTIONThis study aimed to investigate the therapeutic response to injected human umbilical cord blood mesenchymal stem cells (UCBMSCs) among albino rats with streptozotocin (STZ)-induced diabetes mellitus.METHODSControl group (GI; n = 25) rats were fed with standard rat diet. Rats with STZ-induced diabetes mellitus without (GII; n = 25) and with (GIII; n = 25) differentiated human UCBMSCs implantation were the test groups. Rats were sacrificed in Week 11 following implantation. Liver biopsies were sectioned and stained in order to highlight both the presence and function of impregnated cells in the liver tissue.RESULTSHaematoxylin and eosin-stained sections in GI and GII rats showed normal liver architecture while GIII rats showed presence of cell clusters inside the liver tissue and around the central veins. Cell clusters with blue cytoplasm were present in sections in GIII rats but absent in GI and GII rats, indicating the presence of injected differentiated human UCBMSCs. The anti-human insulin immunostaining of GIII rats showed clusters of cells within the liver parenchyma and around central veins, indicating that these cells were active and secreting insulin.CONCLUSIONUCBMSCs are proficient in differentiating into insulin-producing cells in vivo under specific conditions and, when transplanted into the liver of albino rats with STZ-induced diabetes mellitus, were able to secrete insulin and partially control the status of diabetes mellitus in rats.     

Perception of the Quality of Communication With Physicians Among Relatives of Dying Residents of Long-term Care Facilities in 6 European Countries: PACE Cross-Sectional Study

ObjectiveTo examine how relatives evaluate the quality of communication with the treating physician of a dying resident in long-term care facilities (LTCFs) and to assess its differences between countries.DesignA cross-sectional retrospective study in a representative sample of LTCFs conducted in 2015. Relatives of residents who died during the previous 3 months were sent a questionnaire.Settings and participants761 relatives of deceased residents in 241 LTCFs in Belgium, England, Finland, Italy, the Netherlands, and Poland.MethodsThe Family Perception of Physician-Family Communication (FPPFC) scale (ratings from 0 to 3, where 3 means the highest quality) was used to retrospectively assess how the quality of end-of-life communication with treating physicians was perceived by relatives. We applied multilevel linear and logistic regression models to assess differences between countries and LTCF types.ResultsThe FPPFC score was the lowest in Finland (1.4 ± 0.8) and the highest in Italy (2.2 ± 0.7). In LTCFs served by general practitioners, the FPPFC score differed between countries, but did not in LTCFs with on-site physicians. Most relatives reported that they were well informed about a resident's general condition (from 50.8% in Finland to 90.6% in Italy) and felt listened to (from 53.1% in Finland to 84.9% in Italy) and understood by the physician (from 56.7% in Finland to 85.8% in Italy). In most countries, relatives assessed the worst communication as being about the resident's wishes for medical treatment at the end of life, with the lowest rate of satisfied relatives in Finland (37.6%).ConclusionThe relatives' perception of the quality of end-of-life communication with physicians differs between countries. However, in all countries, physicians' communication needs to be improved, especially regarding resident's wishes for medical care at the end of life.ImplicationsTraining in end-of-life communication to physicians providing care for LTCF residents is recommended.
