Clinical and demographic factors modify the association between plasma phosphorylated tau-181 and cognition.

Introduction: Plasma phosphorylated tau-181 (p-tau181) associations with global cognition and memory are clear, but the link between p-tau181 with other cognitive domains and subjective cognitive decline (SCD) across the clinical spectrum of Alzheimer's disease (AD) and how this association changes based on genetic and demographic factors is poorly understood.

Methods: Participants were drawn from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and included 1185 adults >55 years of age with plasma p-tau181 and neuropsychological test data. Linear regression models related plasma p-tau181 to neuropsychological composite and SCD scores with follow-up models examining plasma p-tau181 interactions with cognitive diagnosis, apolipoprotein E ε4 carrier status, age, and sex on cognitive outcomes.

Comparison of patients undergoing protected high risk percutaneous coronary intervention using either intravascular lithotripsy or rotational atherectomy.

Background: Treating heavily calcified vessels is a challenging task in patients with an impaired left ventricular ejection fraction. Percutaneous mechanical circulatory support (pMCS) is increasingly used in patients in high-risk percutaneous coronary intervention (HRPCI).

Methods: In this retrospective registry, we investigated 25 patients undergoing a protected HRPCI receiving either intravascular lithotripsy (IVL + pMCS;  = 11) or rotational atherectomy (RA + pMCS;  = 14).

Melatonin in Alzheimer's Disease: Literature Review and Therapeutic Trials.

There are currently no effective treatments to prevent, halt, or reverse Alzheimer's disease (AD), the most common cause of dementia in older adults. Melatonin, a relatively harmless over-the-counter supplement, may offer some benefits to patients with AD. Melatonin is known for its sleep-enhancing properties, but research shows that it may provide other advantages as well, such as antioxidant and anti-amyloidogenic properties.

Digital Microfluidics for Sample Preparation in Low-Input Proteomics.

Low-input proteomics, also referred to as micro- or nanoproteomics, has become increasingly popular as it allows one to elucidate molecular processes in rare biological materials. A major prerequisite for the analytics of minute protein amounts, e.g.

Lung Clearance Index as a Screening Parameter of Pulmonary Impairment in Patients under Immune Checkpoint Therapy: A Pilot Study.

Immune checkpoint blockade (ICB) has presented a breakthrough in the treatment of malignant tumors and increased the overall survival of patients with various tumor entities. ICB may also cause immune-related adverse events, such as pneumonitis or interstitial lung disease. The lung clearance index (LCI) is a multiple-breath washout technique offering information on lung pathology in addition to conventional spirometry.

5qSMA: standardised retrospective natural history assessment in 268 patients with four copies of SMN2.

Newborn screening for 5qSMA offers the potential for early, ideally pre-symptomatic, therapeutic intervention. However, limited data exist on the outcomes of individuals with 4 copies of SMN2, and there is no consensus within the SMA treatment community regarding early treatment initiation in this subgroup. To provide evidence-based insights into disease progression, we performed a retrospective analysis of 268 patients with 4 copies of SMN2 from the SMArtCARE registry in Germany, Austria and Switzerland.

Impact of an automated, remote monitoring and coaching intervention in reducing hospice cancer family caregiving burden: A multisite randomized controlled trial.

Background: Care for those with life-limiting cancer heavily involves family caregivers who may experience significant physical and emotional burden. The purpose of this study was to test the impact of Symptom Care at Home (SCH), an automated digital family caregiver coaching intervention, during home hospice, when compared to usual hospice care (UC) on the primary outcome of overall caregiver burden. Secondary outcomes included Caregiver Burden at weeks 1 and 8, Mood and Vitality subscales, overall moderate-to-severe caregiving symptoms, and sixth month spouse/partner bereavement outcomes.

Branching Exponents of Synthetic Vascular Trees Under Different Optimality Principles.

Objective: The branching behavior of vascular trees is often characterized using Murray's law. We investigate its validity using synthetic vascular trees generated under global optimization criteria.

Methods: Our synthetic tree model does not incorporate Murray's law explicitly.

Clinical and demographic factors modify the association between plasma phosphorylated tau-181 and cognition.

Introduction: Plasma phosphorylated tau181 (p-tau181) associations with global cognition and memory are clear, but the link between p-tau181 with other cognitive domains and subjective cognitive decline (SCD) across the clinical spectrum of Alzheimer's disease (AD) and how this association changes based on genetic and demographic factors is poorly understood.

Methods: Participants were drawn from the Alzheimer's Disease Neuroimaging Initiative and included 1185 adults aged >55 years with plasma p-tau181 and neuropsychological test data. Linear regression models related plasma p-tau181 to neuropsychological composite and SCD scores with follow-up models examining plasma p-tau181 interactions with cognitive diagnosis, ε4 carrier status, age, and sex on cognitive outcomes.

Nursing Care Throughout the Chimeric Antigen Receptor T-Cell Therapy Process for Multiple Myeloma.

Objectives: Approvals of chimeric antigen receptor T-cell (CAR-T) therapies for relapsed/refractory multiple myeloma (RRMM) represent advancements in treatment options for a hard-to-treat population. Nursing care during CAR-T therapy is crucial for patients, their caregivers, and the broader CAR-T therapy care team. This manuscript provides an overview of the CAR-T therapy administration process and describes practical considerations for nursing professionals working with patients who receive CAR-T therapy.

Family and literature analysis demonstrates phenotypic effect of two variants in the calpain-3 gene.

Both, recessive (LGMD R1) and dominant (LGMD D4) inheritance occur in calpain 3-related muscular dystrophy. We report a family with calpain-related muscular dystrophy caused by two known variants in the calpain 3 gene (CAPN3, NM_000070.3; (I) c.

Systematic single amino acid affinity tuning of CD229 CAR T cells retains efficacy against multiple myeloma and eliminates on-target off-tumor toxicity.

T cells expressing chimeric antigen receptors (CARs) have shown remarkable therapeutic activity against different types of cancer. However, the wider use of CAR T cells has been hindered by the potential for life-threatening toxicities due to on-target off-tumor killing of cells expressing low amounts of the target antigen. CD229, a signaling lymphocyte-activation molecule (SLAM) family member, has previously been identified as a target for CAR T cell-mediated treatment of multiple myeloma (MM) due to its high expression on the surfaces of MM cells.

Digital Microfluidics and Magnetic Bead-Based Intact Proteoform Elution for Quantitative Top-down Nanoproteomics of Single C. elegans Nematodes.

While most nanoproteomics approaches for the analysis of low-input samples are based on bottom-up proteomics workflows, top-down approaches enabling proteoform characterization are still underrepresented. Using mammalian cell proteomes, we established a facile one-pot sample preparation protocol based on protein aggregation on magnetic beads and intact proteoform elution using 40 % formic acid. Performed on a digital microfluidics device, the workflow enabled sensitive analyses of single Caenorhabditis elegans nematodes, thereby increasing the number of proteoform identifications compared to in-tube sample preparation by 46 %.

Technology-Assisted mHealth Caregiver Support to Manage Cancer Patient Symptoms: A Randomized Controlled Trial.

Context: Caregivers managing symptoms of family members with cancer during home hospice care, often feel ill-prepared and need patient care coaching.

Objectives: This study tested the efficacy of an automated mHealth platform that included caregiver coaching on patient symptom care and nurse notifications of poorly controlled symptoms. The primary outcome was caregiver perception of patients' overall symptom severity throughout hospice care and at weeks one, two, four, and eight.

This short review provides recent insights regarding the use of NAMs in ERA of food and feed chemicals. We highlight the usefulness of tiered methods supporting weight-of-evidence approaches in relation to problem formulation (i.

Improvements in Walking Distance during Nusinersen Treatment - A Prospective 3-year SMArtCARE Registry Study.

Background And Objectives: Disease progression in patients with spinal muscular atrophy (SMA) has changed dramatically within the past years due to the approval of three different disease-modifying treatments. Nusinersen was the first drug to be approved for the treatment of SMA patients. Clinical trials provided data from infants with SMA type 1 and children with SMA type 2, but there is still insufficient evidence and only scarcely reported long-term experience for nusinersen treatment in ambulant patients.

SABMIS: sparse approximation based blind multi-image steganography scheme.

We hide grayscale secret images into a grayscale cover image, which is considered to be a challenging steganography problem. Our goal is to develop a steganography scheme with enhanced embedding capacity while preserving the visual quality of the stego-image as well as the extracted secret image, and ensuring that the stego-image is resistant to steganographic attacks. The novel embedding rule of our scheme helps to hide secret image sparse coefficients into the oversampled cover image sparse coefficients in a staggered manner.

GABA-A Receptor Encephalitis After Autologous Hematopoietic Stem Cell Transplant forMultiple Myeloma: Three Cases and Literature Review.

Background And Objectives: The relationship between autologous hematopoietic stem cell transplant (aHSCT) for multiple myeloma (MM) and anti-GABA receptor (GABAR) encephalitis is unknown. We aimed to describe the clinical features, diagnostic process, and outcome of 3 cases of anti-GABAR encephalitis in patients with a history of prior aHSCT for MM.

Methods: A case series of 3 patients.

A Focus on Special Populations in Relapsed Multiple Myeloma.

The overall care of patients with multiple myeloma can present similar challenges. However, disparities in health care require that providers consider each individual's unique circumstances. Disparities based on ethnic/racial group, religion, socioeconomic status, age, sexual orientation or gender identity, or other characteristics can lead to patients receiving less than optimal care and therefore poorer outcomes.

Toxicity management strategies for next-generation novel therapeutics in multiple myeloma.

The therapeutic options available for patients with multiple myeloma have greatly expanded over the past decade and incorporating these novel agents into routine clinical practice has significantly improved outcomes. The next generation of therapeutics is available for relapsed and refractory patients either as standard of care or in clinical trial, and these drugs represent a generational paradigm shift. Patients now have access to a multitude of novel immunotherapeutics, including monoclonal antibodies, an antibody-drug conjugate, chimeric antigen receptor T-cells (CAR-T), and bispecific T-cell redirecting antibodies, and novel oral therapies including selinexor (selective inhibitor of nuclear export) and venetoclax (bcl-2 inhibitor).
