Advanced neuroimaging in neuropsychiatric systemic lupus erythematosus.

Purpose Of Review: Neuropsychiatric lupus (NPSLE) comprises a disparate collection of syndromes affecting the central and peripheral nervous systems. Progress in the attribution of neuropsychiatric syndromes to SLE-related mechanisms and development of targeted treatment strategies has been impeded by a lack of objective imaging biomarkers that reflect specific neuropsychiatric syndromes and/or pathologic mechanisms. The present review addresses recent publications of neuroimaging techniques in NPSLE.

Changes in prostate-specific antigen at the time of prostate cancer diagnosis after Medicaid expansion in young men.

Background: The objective of this study was to determine the effect of Medicaid expansion under the Patient Protection and Affordable Care Act (January 1, 2014) on the epidemiology of high-risk prostate-specific antigen (PSA) levels (≥20 ng/mL) at the time of prostate cancer (PCa) diagnosis. The authors hypothesized that better access to care would result in a reduction of high-risk features at diagnosis.

Methods: A retrospective cohort study was performed of 122,324 men aged <65 years who were diagnosed with PCa within the National Cancer Database.

Intravenous immunoglobulin significantly reduces exposure of concomitantly administered anti-C5 monoclonal antibody tesidolumab.

Awareness of drug-drug interactions is critical in organ transplant recipient management. However, biologic agents interfering with monoclonal antibodies is not widely considered. We report the effect of high-dose intravenous immunoglobulin (IVIg) on safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of the human anti-C5 monoclonal antibody tesidolumab (LFG316) in end-stage renal disease patients awaiting kidney transplant.

Medicaid Expansion Did not Improve Time to Treatment for Young Patients With Metastatic Renal Cell Carcinoma.

Introduction: The absence of health insurance coverage has been associated with worse outcomes for patients with metastatic renal cell carcinoma (mRCC). Medicaid expansion in the United States was an important provision of the Affordable Care Act, which increased the number of low-income individuals eligible for Medicaid starting in January 2014 in several states. The effect of Medicaid expansion on access to healthcare for patients with mRCC is unknown.

Interleukin-6: An Important Mediator of Allograft Injury.

Interleukin-6 (IL-6) is a cytokine with critical innate and adaptive immunity functions. Its diverse immunological and physiological actions include direction of immune cell differentiation, initial response to invading pathogens and ischemic injury, sustained plasma cell growth, and immunoglobulin production. IL-6 transcriptional dysregulation is commonly seen in patients with autoimmune or inflammatory disorders.

Long-Term Outcome of Thrombolytic Therapy for Massive Pulmonary Embolism in Pregnancy.

A 25-year-old pregnant woman presented at 12 weeks of gestation with syncope and shortness of breath caused by massive pulmonary embolism. Due to persistent shock, fibrinolytic therapy with rtPA was administered. After fibrinolysis, clinical and hemodynamic response was excellent.

Promoting appropriate utilisation of laboratory tests for inflammation at an academic medical centre.

Erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) are commonly ordered in clinical practice to evaluate for inflammation. CRP is a more sensitive and specific test for detecting acute phase inflammation, and the American Society for Clinical Pathology recommends ordering CRP rather than ESR to detect acute phase inflammation in patients with undiagnosed conditions. We sought to understand CRP and ESR ordering practices and reduce unnecessary use of ESR testing at our academic medical centre.

Pure Red Cell Aplasia with Del(20q) Sensitive for Immunosuppressive Treatment.

Pure red cell aplasia (PRCA) is a rare syndrome that only affects the erythroid lineage. It is defined by a normocytic, normochromic anemia with a marked reticulocytopenia and severe reduction or absence of erythroid precursors in the bone marrow. Treatment of primary, idiopathic PRCA is immunosuppressive therapy.

Patient Co-Participation in Narrative Medicine Curricula as a Means of Engaging Patients as Partners in Healthcare: A Pilot Study Involving Medical Students and Patients Living with HIV.

This paper describes a pilot study of a new model for narrative medicine training, "community-based participatory narrative medicine" (CBPNM), which centers on shared narrative work between healthcare trainees and patients. Nine medical students and eight patients participated in one of two, five-week-long pilot workshop series. A case study of participants' experiences of the workshop series identified three major themes: (1) the reciprocal and collaborative nature of participants' relationships; (2) the interplay between self-reflection and receiving feedback from others; and (3) the clinical and pedagogical implications of the CBPNM model.

CFTR dysregulation drives active selection of the gut microbiome.

Patients with cystic fibrosis (CF) have altered fecal microbiomes compared to those of healthy controls. The magnitude of this dysbiosis correlates with measures of CF gastrointestinal (GI) disease, including GI inflammation and nutrient malabsorption. However, whether this dysbiosis is caused by mutations in the CFTR gene, the underlying defect in CF, or whether CF-associated dysbiosis augments GI disease was not clear.

Fecal dysbiosis in infants with cystic fibrosis is associated with early linear growth failure.

Most infants with cystic fibrosis (CF) have pancreatic exocrine insufficiency that results in nutrient malabsorption and requires oral pancreatic enzyme replacement. Newborn screening for CF has enabled earlier diagnosis, nutritional intervention and enzyme replacement for these infants, allowing most infants with CF to achieve their weight goals by 12 months of age. Nevertheless, most infants with CF continue to have poor linear growth during their first year of life.

Arthroscopic Resection of Symptomatic Bennett Lesions.

Bennett lesions, also known as "thrower's exostosis" of the shoulder, involve ossification of the posteroinferior glenoid and are not uncommon in overhead throwing athletes. The literature surrounding the optimal operative management of the symptomatic Bennett lesion is limited. The purpose of this article is to describe the arthroscopic surgical technique for the visualization and excision of the symptomatic extra-articular pathologic ossification involving the posteroinferior glenoid.

Three-Year Outcomes of a Randomized, Double-Blind, Placebo-Controlled Study Assessing Safety and Efficacy of C1 Esterase Inhibitor for Prevention of Delayed Graft Function in Deceased Donor Kidney Transplant Recipients.

Background And Objectives: Delayed graft function is related to ischemia-reperfusion injury and may be complement dependent. We previously reported from a randomized, placebo-controlled trial that treatment with C1 esterase inhibitor was associated with a shorter duration of delayed graft function and higher eGFR at 1 year. Here, we report longer-term outcomes from this trial.

Impact of geriatrics elective courses at three colleges of pharmacy: Attitudes toward aging and eldercare.

Introduction: One in five Americans will be 65 years and older by 2030. Training student pharmacists to provide quality eldercare as healthcare professionals is essential. The objective of the study was to assess pharmacy students' attitudes toward aging and eldercare before and after a geriatrics-focused elective course.

LRRK2 and GBA Variants Exert Distinct Influences on Parkinson's Disease-Specific Metabolic Networks.

The natural history of idiopathic Parkinson's disease (PD) varies considerably across patients. While PD is generally sporadic, there are known genetic influences: the two most common, mutations in the LRRK2 or GBA1 gene, are associated with slower and more aggressive progression, respectively. Here, we applied graph theory to metabolic brain imaging to understand the effects of genotype on the organization of previously established PD-specific networks.

Learning curve in minimally invasive mitral valve surgery: a single-center experience.

Background: Minimally invasive mitral valve surgery is becoming a gold standard and provides many advantages for patients. A learning curve is required for a surgeon to become proficient, and the exact number to overcome this curve is controversial. Our study aimed to define this number for mitral valve surgery in general, for replacement and repair separately.

An Overview of Machine Learning and Big Data for Drug Toxicity Evaluation.

Drug toxicity evaluation is an essential process of drug development as it is reportedly responsible for the attrition of approximately 30% of drug candidates. The rapid increase in the number and types of large toxicology data sets together with the advances in computational methods may be used to improve many steps in drug safety evaluation. The development of in silico models to screen and understand mechanisms of drug toxicity may be particularly beneficial in the early stages of drug development where early toxicity assessment can most reduce expenses and labor time.

Minimally Invasive Mitral Valve Surgery for Rheumatic Valve Disease.

Background: The development of minimally invasive mitral valve surgery has created the motivation for using this approach in young patients with chronic rheumatic valve disease. We report our recent experience with patients undergoing minimally mitral valve surgery in this group of patients.

Methods: Between July 2014 and June 2018, 142 patients with rheumatic mitral valve dysfunction underwent minimally invasive surgery through a right thoracotomy approach at the University Medical Center of Ho Chi Minh City in Vietnam.

Outcomes of Conversion From Calcineurin Inhibitor to Belatacept-based Immunosuppression in HLA-sensitized Kidney Transplant Recipients.

Background: The efficacy and safety of belatacept when converted from calcineurin inhibitors (CNI) in HLA-sensitized (HS) kidney transplant recipients has not been established.

Methods: The study included 108 kidney transplant recipients converted from CNI to belatacept between July 1, 2012, and September 30, 2017. Rejection-free, patient, and graft survival over 5 years follow-up were compared between HS and non-HLA-sensitized (non-HS) recipients using the Kaplan-Meier product-limit method.

Understanding drug distribution and release in ophthalmic emulsions through quantitative evaluation of formulation-associated variables.

Establishing bioequivalence (BE) of ophthalmic emulsions in the absence of in vivo data is challenging. In these emulsions, drug release is a complex process due to drug distribution among various phases which are difficult to characterize. The objective of this study is to investigate the process of drug distribution and mechanism of drug release in the context of formulation-associated variables.

Rich Text Formatted EHR Narratives: A Hidden and Ignored Trove.

This study presents an approach for mining structured information from clinical narratives in Electronic Health Records (EHRs) by using Rich Text Formatted (RTF) records. RTF is adopted by many medical information management systems. There is rich structural information in these files which can be extracted and interpreted, yet such information is largely ignored.

Implications of Fc Neonatal Receptor (FcRn) Manipulations for Transplant Immunotherapeutics.

Alloimmune injury to allografts is mediated by pathogenic donor-specific alloantibodies, usually of the IgG isotype. Currently, strategies used to reduce donor-specific alloantibodies are collectively called desensitization. Despite successes, these treatments have limited efficacy and can be associated with adverse events, infectious complications, and high cost.

Impact of Tocilizumab (Anti-IL-6R) Treatment on Immunoglobulins and Anti-HLA Antibodies in Kidney Transplant Patients With Chronic Antibody-mediated Rejection.

Background: Chronic antibody-mediated rejection (cAMR) results in the majority of renal allograft losses. Currently, there are no approved therapies. We recently reported on clinical use of tocilizumab (TCZ) for treatment of cAMR in HLA-sensitized kidney transplant patients.

Cancer classification and pathway discovery using non-negative matrix factorization.

Objectives: Extracting genetic information from a full range of sequencing data is important for understanding disease. We propose a novel method to effectively explore the landscape of genetic mutations and aggregate them to predict cancer type.

Design: We applied non-smooth non-negative matrix factorization (nsNMF) and support vector machine (SVM) to utilize the full range of sequencing data, aiming to better aggregate genetic mutations and improve their power to predict disease type.

Safety, pharmacokinetics, and pharmacodynamic activity of obinutuzumab, a type 2 anti-CD20 monoclonal antibody for the desensitization of candidates for renal transplant.

The limited effectiveness of rituximab plus intravenous immunoglobulin (IVIG) in desensitization may be due to incomplete B cell depletion. Obinutuzumab is a type 2 anti-CD20 antibody that induces increased B cell depletion relative to rituximab and may therefore be more effective for desensitization. This open-label phase 1b study assessed the safety, pharmacokinetics, and pharmacodynamics of obinutuzumab in highly sensitized patients with end-stage renal disease.
