Azole antifungals and new targeted therapies for hematological malignancy.

Purpose Of Review: With the introduction of new targeted therapies for hematological malignancies comes the challenges of both assessing the risk of developing an IFD while being treated with these agents, as well as managing the drug--drug interactions between azole antifungals and the agents.

Recent Findings: New targeted therapies for hematological malignancy include chimeric antigen receptor T cells (CAR T cells), Bi-specific T-cell Engager (BiTE) blinatumomab, and the antibody-drug conjugate (ADC) of calicheamicin inotuzumab ozogamicin for acute lymphoblasic leukemia (ALL) and lymphoma; the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib and phosphatidylinositol 3-kinase (PI3Kδ) inhibitor idelalisib for lymphoma and graft-versus-host disease (GVHD); FMS-like tyrosine kinase 3 (FLT3) inhibitors, such as midostaurin, sorafenib and gilteritinib for acute myeloid leukemia (AML); and the BCL-2 inhibitor venetoclax for a range of hematological malignancies including lymphoma and leukemia. This review summarizes recommendations for IFD prophylaxis using these therapies and evidence for managing concomitant azole administration.

Current Practices in Electronic Capture of Patient-Reported Outcomes for Measurement-Based Care and the Use of Patient Portals to Support Behavioral Health.

Electronic health records combined with tethered patient portals now support a range of functions including electronic data capture of patient-reported outcomes, trend reporting on clinical targets, secure messaging, and patient-mediated health information exchange. The applications of these features require special consideration in psychiatric and behavioral health settings. Nonetheless, their potential to engage patients suffering from disorders in which passivity and withdrawal are endemic to their mental health condition, is great.

Clinical Lessons from Virtual House Calls in Mental Health: The Doctor Is in the House.

Video-to-home (VTH) is a patient-centered approach to delivering mental health care that has increased the reach of care to patients who face considerable logistical and sociocultural barriers. Despite high rates of patient satisfaction and acceptance of VTH, scholarly resources for expanding providers' comfort and competence using VTH are limited to emergency preparedness or remotely managing higher risk patients. This article highlights other potential benefits, adaptations, and considerations for providers interested in expanding their use of VTH to engage patients who are difficult to reach or who have complex presentations.

UK Patients of Bangladeshi Descent with Crohn's Disease Respond Less Well to TNF Antagonists Than Caucasian Patients.

Background: Patients with inflammatory bowel disease are currently managed with the assumption that trial data are applicable to all ethnic groups. Previous studies demonstrate differences in disease severity and phenotype of Asian patients with Crohn's disease (CD), including Bangladeshi Asians within the UK. No study has evaluated the impact of ethnicity on response to anti-TNFs.

Response-adapted intensification with cyclophosphamide, bortezomib, and dexamethasone versus no intensification in patients with newly diagnosed multiple myeloma (Myeloma XI): a multicentre, open-label, randomised, phase 3 trial.

Background: Multiple myeloma has been shown to have substantial clonal heterogeneity, suggesting that agents with different mechanisms of action might be required to induce deep responses and improve outcomes. Such agents could be given in combination or in sequence on the basis of previous response. We aimed to assess the clinical value of maximising responses by using therapeutic agents with different modes of action, the use of which is directed by the response to the initial combination therapy.

Mathematical modelling to study the horizontal transfer of antimicrobial resistance genes in bacteria: current state of the field and recommendations.

Antimicrobial resistance (AMR) is one of the greatest public health challenges we are currently facing. To develop effective interventions against this, it is essential to understand the processes behind the spread of AMR. These are partly dependent on the dynamics of horizontal transfer of resistance genes between bacteria, which can occur by conjugation (direct contact), transformation (uptake from the environment) or transduction (mediated by bacteriophages).

New advances in the management of cytomegalovirus in allogeneic haemopoietic stem cell transplantation.

Cytomegalovirus (CMV) viraemia continues to be a frequent complication in the post-haemopoietic stem cell transplantation period despite a low incidence of CMV end-organ disease. Several significant advances in the understanding and management of CMV infection have occurred in the last few years including improved diagnostics, monitoring of CMV immunity, availability of novel anti-CMV drugs, and emerging use of immunotherapies including CMV-specific T-cell infusions. In addition to reviewing these advances we also explore some of the more practical prescribing issues of the older and newer CMV drugs including cost, toxicity and drug interactions to help clinicians navigate this new era of CMV management.

This cross-country longitudinal cohort of 2310 deeply phenotyped subjects with various forms of dementia and mild memory loss or concerns, along with cognitively intact elderly subjects, will test hypotheses generated by these teams.

Methods: The COMPASS-ND protocol, initial grant proposal for funding, fifth semi-annual CCNA Progress Report submitted to the Canadian Institutes of Health Research December 2017, and other documents supplemented by modifications made and lessons learned after implementation were used by the authors to create the description of the study provided here.

Exposure to polychlorinated biphenyls and organochlorine pesticides and risk of dementia, Alzheimer's disease and cognitive decline in an older population: a prospective analysis from the Canadian Study of Health and Aging.

Background: Little attention has been paid to neurotoxicants on the risk of dementia. Exposure to known neurotoxicants such as polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticides is suspected to have adverse cognitive effects in older populations.

Objective: To assess whether plasma concentrations of PCBs and OC pesticides are associated with the risk of cognitive decline, Alzheimer's disease (AD) and of all-cause dementia in the Canadian older population.

Autologous stem cell transplantation in refractory Crohn's disease - low intensity therapy evaluation (ASTIClite): study protocols for a multicentre, randomised controlled trial and observational follow up study.

Background: Intestinal inflammation in Crohn's disease (CD) is caused by mucosal immune system reactivity to luminal antigen and results in debilitating symptoms, reduced quality of life, impaired work productivity and significant health care costs. Not all patients respond to conventional and biologic therapies, with chronic inflammation ensuing. Although surgical resection may be required, disease frequently returns and surgery may not be an option, or may be declined.

Perceptions and psychosocial impact of food, nutrition, eating and drinking in people with inflammatory bowel disease: a qualitative investigation of food-related quality of life.

Introduction: Extensive research has provided an important understanding of the impact of inflammatory bowel disease (IBD) on nutrient intake, requirements and metabolism. By contrast, there has been limited research examining the psychosocial aspects of food, eating and drinking in IBD. The present study aimed to address this unmet need.

Pomalidomide, bortezomib, and dexamethasone for patients with relapsed or refractory multiple myeloma previously treated with lenalidomide (OPTIMISMM): a randomised, open-label, phase 3 trial.

Background: As lenalidomide becomes increasingly established for upfront treatment of multiple myeloma, patients refractory to this drug represent a population with an unmet need. The combination of pomalidomide, bortezomib, and dexamethasone has shown promising results in phase 1/2 trials of patients with relapsed or refractory multiple myeloma. We aimed to assess the efficacy and safety of this triplet regimen in patients with relapsed or refractory multiple myeloma who previously received lenalidomide.

Genetic resistance determinants to fusidic acid and chlorhexidine in variably susceptible staphylococci from dogs.

Background: Concern exists that frequent use of topically-applied fusidic acid (FA) and chlorhexidine (CHX) for canine pyoderma is driving clinically relevant resistance, despite rare description of FA and CHX genetic resistance determinants in canine-derived staphylococci. This study aimed to determine minimum inhibitory concentrations (MICs) and investigate presence of putative resistance determinants for FA and CHX in canine-derived methicillin-resistant (MR) and -susceptible (MS) staphylococci. Plasmid-mediated resistance genes (fusB, fusC, fusD, qacA/B, smr; PCR) and MICs (agar dilution) of FA and CHX were investigated in 578 staphylococci (50 MR S.

Recommendations for classification of commercial LBA kits for biomarkers in drug development from the GCC for bioanalysis.

Over the last decade, the use of biomarker data has become integral to drug development. Biomarkers are not only utilized for internal decision-making by sponsors; they are increasingly utilized to make critical decisions for drug safety and efficacy. As the regulatory agencies are routinely making decisions based on biomarker data, there has been significant scrutiny on the validation of biomarker methods.

A hydrochemically guided landscape classification system for modelling spatial variation in multiple water quality indices: Process-attribute mapping.

Spatial variation in landscape attributes can account for much of the variability in water quality relative to land use on its own. Such variation results from the coupling between the dominant processes governing water quality, namely hydrological, redox, and weathering and gradients in key landscape attributes, such as topography, geology, and soil drainage. Despite the importance of 'process-attribute' gradients (PAG), few water quality models explicitly account for their influence.

Determinants of Phage Host Range in Species.

Bacteria in the genus are important targets for phage therapy due to their prevalence as pathogens and increasing antibiotic resistance. Here we review outer surface features and specific phage resistance mechanisms that define the host range, the set of strains that an individual phage can potentially infect. Phage infection goes through five distinct phases: attachment, uptake, biosynthesis, assembly, and lysis.

Staphylococcus aureus Bacteremia in Children of Rural Areas of The Gambia, 2008-2015.

Staphylococcus aureus bacteremia is a substantial cause of childhood disease and death, but few studies have described its epidemiology in developing countries. Using a population-based surveillance system for pneumonia, sepsis, and meningitis, we estimated S. aureus bacteremia incidence and the case-fatality ratio in children <5 years of age in 2 regions in the eastern part of The Gambia during 2008-2015.
