1 µmol.L-1 concentration tested. The PDT also triggered significant morphological alterations in the Leishmania promastigotes. These results reinforce the idea that the use of PGN as photosensitizers carriers is useful for PDT of Leishmania promastigotes.Objective SARS-CoV-2 infection and its oft-associated illness COVID-19 may lead to neuropsychological deficits, either through direct mechanisms (i.e., neurovirulance) or indirect mechanisms, most notably complications caused by the virus (e.g., stroke) or medical procedures (e.g., intubation). The history of past human coronavirus outbreaks resulting in similar health emergencies suggests there will be a substantial prevalence of post-traumatic stress disorder (PTSD) among COVID-19 survivors. To prepare neuropsychologists for the difficult task of differentiating PTSD-related from neuropathology-related deficits in the oncoming wave of COVID-19 survivors, we integrate research across a spectrum of related areas.Methods Several areas of literature were reviewed psychiatric, neurologic, and neuropathological outcomes of SARS and MERS patients; neurological outcomes in COVID-19 survivors; PTSD associated with procedures common to COVID-19 patients; and differentiating neuropsychological deficits due to PTSD from those due to acquired brain injuries in other patient groups.Conclusions Heightened risk of PTSD occurred in MERS and SARS survivors. While data concerning COVID-19 is lacking, PTSD is known to occur in patient groups who undergo similar hospital courses, including ICU survivors, patients who are intubated and mechanically ventilated, and those that experience delirium. Research with patients who develop PTSD in the context of mild traumatic brain injury further suggests that PTSD may account for some or all of a patient's subjective cognitive complaints and neuropsychological test performance. Recommendations are provided for assessing PTSD in the context of COVID-19.Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease caused by the death of motor neurons. Riluzole is a benzothiazole derivative that blocks glutamatergic neurotransmission in the CNS, which is thought to exert neuroprotective effects. Riluzole was approved by the US FDA in 1995 as the first drug to treat ALS. Although riluzole is generally safe and well tolerated in clinical practice, its efficacy in ALS is modest, prolonging tracheostomy-free survival by only 2-3 months. In this article, we will first provide an overview of the ALS field, followed by a discussion of riluzole regarding its physical properties; pharmacology; clinical efficacy in ALS; safety and tolerability; and recommended administration.

Prostate cancer is the second leading cause of cancer death in men. Androgen deprivation therapy (ADT) has been the primary therapeutic approach for treatment of prostate cancer. However,nearly all patients develop the castration-resistant disease . We evaluated real-world data with abiraterone and enzalutamide treatment. By this data, we aimed to analyze whether that prior short response to ADT could predict response to subsequent therapy with androgen receptor axis targeted agent (ARATA).

We collected data from two cancer centers, 151 consecutive patients with treated abiraterone or enzalutamide in the first line of metastatic castration resistant prostat cancer (mCRPC) setting were included. The patients who received docetaxel in castration naive setting is also included. Time to castration resistance (TTCR) was defined as the duration from the initial to failure of primary ADT.

Patients with treated ARATA were divided into two groups according to the time to castration resistance (TTCR). Patients who became resistant to ADT up to one year had a median PFS of 6.6 months, compared to median PFS of 13.3 months for patients who responded ADT for more than 1 year. (p = 0.002). In the post-docetaxel setting, median PFS is 12.6 months of patients with treated ARATA who had TTCR for more than one year, and median PFS is 6.6 months in those who had TTCR less than one year (p = 0.007).Univariate and multivariate analyses were performed to determine the clinical factors on ARATA outcomes. Eastern Cooperative Oncology Group (ECOG) performance status(PS), median prostate-specific antigen(PSA) and time to CRPC were significantly predicted outcomes of ARATA on multivariate analysis.

TTCR is also a predictor for PFS of the patients who were treated ARATA both whole cohort and post-docetaxel.

Exposure to anticancer drugs is one of the known risks for people working in specialist oncology units. Wearing gloves is a vital form of personal protection. The aim of this study was to assess, in close to real use dynamic conditions, the permeability of 15 surgical and examination gloves made from different materials when exposed to 27 anticancer drugs included in the list from international Guides and Recommendations.

Gloves were tested by using controlled dynamic conditions replicating flexion and extension movements that mimic typical clinical applications. Tests were performed at 37°C or at 43°C for 30 min and anticancer drugs were tested at the highest concentration used in clinical practice. To determine the permeation rate, the quantification of anticancer drugs was performed with selective and sensitive analytical methods such as inductively coupled plasma-mass spectroscopy and liquid chromatography-mass spectrometry.

All the gloves met the EN 16523-1 European standard (1000 ng/(min.cm

)). The penetration rate of busulfan, carmustine and thiotepa exceeded the ASTM D-6978-05 American standard (10 ng/(min.cm

)) with several surgical and/or examination gloves. This standard was met in all of cases when double gloving was used. Breakage of several nitrile gloves was observed in relation with the excipient used by drugs suppliers.

Permeation is a complex multifactorial phenomenon. However, we have suggested that the thickness of the glove and three physicochemical parameters (molecular weight, topological polar surface area and hydrogen bond donor) of the drug were the main parameters affecting permeation.

Carcinogenesis is driven by an array of complex genomic patterns; these patterns can render an individual resistant or sensitive to certain chemotherapy agents. The Personalized Oncogenomics (POG) project at BC Cancer has performed integrative genomic analysis of whole tumour genomes and transcriptomes for over 700 patients with advanced cancers, with an aim to predict therapeutic sensitivities. The aim of this study was to utilize the POG genomic data to evaluate a discrete set of biomarkers associated with chemo-sensitivity or-resistance in advanced stage breast and colorectal cancer POG patients.

This was a retrospective multi-centre analysis across all BC CANCER sites. All breast and colorectal cancer patients enrolled in the POG program between July 1, 2012 and November 30, 2016 were eligible for inclusion. Within the breast cancer population, those treated with capecitabine, paclitaxel, and everolimus were analyzed, and for the colorectal cancer patients, those treated with capecitabine, bevacizumabession of these genomic biomarkers.

Among breast cancer patients, higher TYMP expression was associated with sensitivity to capecitabine. Among colorectal cancer patients, higher DICER1 expression was associated with sensitivity to bevacizumab-based therapy. This study supports further assessment of the potential predictive value of mRNA expression of these genomic biomarkers.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic malignancy that originates from plasmacytoid dendritic cells. It can involve skin, bone marrow, and/or lymph nodes. There is no consensus recommendation regarding treatment especially in the relapsed setting. Tagraxofusp, a CD123 directed agent, was recently approved by the Food and Drug Administration to treat BPDCN. We report a case of an elderly patient with diagnosis of BPDCN who was treated initially with tagraxofusp followed by azacitidine and venetoclax combination on relapse.

A 79 year old male presented with violaceous skin lesions. He had no other symptoms. Biopsy of these lesions was consistent with a diagnosis of BPDCN. see more Further testing showed no extracutaneous involvement.

Tagraxofusp was started at full dose (12 mcg/kg). This dose was not tolerated well. Patient could only tolerate the lowest dose (5 mcg/kg). Toxicities included elevated liver function tests, hyperglycemia, capillary leak syndrome, and pancreatitis. Dose escalation on progression was not possible due to side effects. Treatment was switched to venetoclax and azacitidine. Combination treatment was tolerated very well and patient showed major cutaneous response after 5 cycles and continues to do well.

Tagraxofusp is a novel therapy that needs more real-world experience. This case describes the clinical course of an elderly patient on tagraxofusp. We also review the literature of azacytidine/venetoclax combination as a potential yet tolerable treatment option for this rare disease entity. This is the fourth case in literature to be treated with this combination.

However, there are major risks inherent to the device, and with modern day technology, their routine use has decreased. We discuss the need for routine insertion of pulmonary artery catheters in cardiac surgery. We also present a case of a left ventricular assist device implantation complicated by serious pulmonary hemorrhage due to pulmonary artery catheter insertion, highlighting the potentially life-threatening risks involved.Objective To describe the challenges related to COVID-19 affecting pediatric neuropsychologists practicing in inpatient brain injury rehabilitation settings, and offer solutions focused on face-to-face care and telehealth.Methods A group of pediatric neuropsychologists from 12 pediatric rehabilitation units in North America and 2 in South America have met regularly since COVID-19 stay-at-home orders were initiated in many parts of the world. This group discussed challenges to clinical care and collaboratively problem-solvedsolutions.Results Three primary challenges to usual care were identified, these include difficulty providing 1) neurobehavioral and cognitive assessments; 2) psychoeducation for caregivers and rapport building; and 3) return to academic instruction and home. Solutions during the pandemic for the first two areas focus on the varying service provision models that include 1) face-to-face care with personal protective equipment (PPE) and social distancing and 2) provision of care via remote methods, with a focus on telehealth.
