Association of anthropometry and weight change with risk of dementia and its major subtypes: A meta-analysis consisting 2.8 million adults with 57 294 cases of dementia.

Uncertainty exists regarding the relation of body size and weight change with dementia risk. As populations continue to age and the global obesity epidemic shows no sign of waning, reliable quantification of such associations is important. We examined the relationship of body mass index, waist circumference, and annual percent weight change with risk of dementia and its subtypes by pooling data from 19 prospective cohort studies and four clinical trials using meta-analysis.

The objective of this article is to describe a tailored intervention carried out to inform the protagonists about the high risk of CRC due to family history and then to understand, through an interdisciplinary analysis, the mechanisms implemented during the intervention.

Method: A randomized trial design was applied.

A, B, or C? A Quasi-experimental Multi-site Study Investigating Three Option Multiple Choice Questions.

There is nearly a century of educational research that has demonstrated that three option multiple-choice questions (MCQs) are as valid and reliable as four or five option, yet this format continues to be underutilized in educational institutions. This replication study was a quasi-experimental between groups research design conducted at three Canadian schools of nursing to examine the psychometric properties of three option MCQs when compared to the more traditional four option questions. Data analysis revealed that there were no statistically significant differences in the item discrimination, difficulty or mean examination scores when MCQs were administered with three versus four option answer choices.

Discovery of Potent and Selective Antibody-Drug Conjugates with Eg5 Inhibitors through Linker and Payload Optimization.

Targeted antimitotic agents are a promising class of anticancer therapies. Herein, we describe the development of a potent and selective antimitotic Eg5 inhibitor based antibody-drug conjugate (ADC). Preliminary studies were performed using proprietary Eg5 inhibitors which were conjugated onto a HER2-targeting antibody using maleimido caproyl valine-citrulline para-amino benzocarbamate, or MC-VC-PABC cleavable linker.

Investigation of antihypertensive class, dementia, and cognitive decline: A meta-analysis.

Objective: High blood pressure is one of the main modifiable risk factors for dementia. However, there is conflicting evidence regarding the best antihypertensive class for optimizing cognition. Our objective was to determine whether any particular antihypertensive class was associated with a reduced risk of cognitive decline or dementia using comprehensive meta-analysis including reanalysis of original participant data.

[Considerable diagnostic variation among memory clinics - is it an issue?].

A recent survey shows a steady growth in the number of memory clinics in the Netherlands over the last two decades. It appears there is considerable variation in both the organization of care and the type of diagnostic work-up that is provided. Over time, the memory clinic population has also changed; 22% of patients present with subjective memory complaints, a three-fold increase.

The Science and (Lost) Art of Psoralen Plus UVA Phototherapy.

PUVA phototherapy is the therapeutic use of psoralens and UVA light to treat inflammatory skin diseases, with psoriasis the prototype disease. Naturally occurring phototoxic compounds, psoralens interact with UVA to suppress DNA synthesis and cell proliferation and induce apoptosis of inflammatory cells. Well-developed therapeutic protocols for psoriasis guide psoralen and UVA doses, treatment frequency, and safety measures, and these protocols also may be used to treat other inflammatory dermatoses.

Normalization of hippocampal retinoic acid level corrects age-related memory deficits in rats.

Dietary micronutrients constitute a major environmental factor influencing aging processes. Vitamin A (vit. A) is the precursor of retinoic acid, a bioactive molecule that controls the expression of several genes involved in brain function.

Intracellular calcium mishandling leads to cardiac dysfunction and ventricular arrhythmias in a mouse model of propionic acidemia.

Propionic acidemia (PA) is a rare metabolic disease associated with mutations in genes encoding the α and β subunits of the enzyme propionyl-CoA carboxylase. The accumulation of toxic metabolites results in mitochondrial dysfunction, increased reactive oxygen species production and oxidative damage, which have been associated with the disease pathophysiology. Clinical symptoms are heterogeneous and include cardiac complications, mainly cardiac dysfunction and arrhythmias, which are recognized as one of the major life-threatening manifestations in patients.

POLR1B and neural crest cell anomalies in Treacher Collins syndrome type 4.

Purpose: Treacher Collins syndrome (TCS) is a rare autosomal dominant mandibulofacial dysostosis, with a prevalence of 0.2-1/10,000. Features include bilateral and symmetrical malar and mandibular hypoplasia and facial abnormalities due to abnormal neural crest cell (NCC) migration and differentiation.

Antigen array for serological diagnosis and novel allergen identification in severe equine asthma.

Severe equine asthma (sEA), which closely resembles human asthma, is a debilitating and performance-limiting allergic respiratory disorder which affects 14% of horses in the Northern Hemisphere and is associated with increased allergen-specific immunoglobulin E (IgE) against a range of environmental proteins. A comprehensive microarray platform was developed to enable the simultaneous detection of allergen-specific equine IgE in serum against a wide range of putative allergenic proteins. The microarray revealed a plethora of novel pollen, bacteria, mould and arthropod proteins significant in the aetiology of sEA.

Retrospective study of cardiovascular disease risk factors among a cohort of combat veterans with lower limb amputation.

Introduction: Previous studies have shown that veterans with lower limb amputation have a higher risk for cardiovascular disease (CVD) compared with population-based controls. American veterans who have served in Iraq and Afghanistan with lower limb amputation may be at a similarly higher risk.

Patients And Methods: The Navel Health Research Center (NHRC) maintains the Expeditionary Medical Encounter Database (EMED) of military personnel who have sustained combat limb amputation or serious limb injury during the conflicts in Iraq and Afghanistan.

Bi-allelic Variants in METTL5 Cause Autosomal-Recessive Intellectual Disability and Microcephaly.

Intellectual disability (ID) is a genetically and clinically heterogeneous disorder, characterized by limited cognitive abilities and impaired adaptive behaviors. In recent years, exome sequencing (ES) has been instrumental in deciphering the genetic etiology of ID. Here, through ES of a large cohort of individuals with ID, we identified two bi-allelic frameshift variants in METTL5, c.

Residual cancer burden index and tumor-infiltrating lymphocyte subtypes in triple-negative breast cancer after neoadjuvant chemotherapy.

Purpose: There is a need to refine the prognosis of triple-negative breast cancer (TNBC) patients after neoadjuvant chemotherapy (NAC) and to study the influence of the tumor microenvironment. We evaluated the prognostic value of pathological and immune markers in TNBC with residual disease (RD) after NAC.

Methods: In a series of 186 TNBC patients treated by NAC, we assessed the prognostic value of the Residual Cancer Burden (RCB) index.

Development of a comprehensive protein microarray for immunoglobulin E profiling in horses with severe asthma.

Background: Severe asthma in horses, known as severe equine asthma (SEA), is a prevalent, performance-limiting disease associated with increased allergen-specific immunoglobulin E (IgE) against a range of environmental aeroallergens.

Objective: To develop a protein microarray platform to profile IgE against a range of proven and novel environmental proteins in SEA-affected horses.

Animals: Six SEA-affected and 6 clinically healthy Warmblood performance horses.

Hypertension management: experiences, wishes and concerns among older people-a qualitative study.

Objectives: Sixty-five per cent of older people have hypertension, but little is known about their preferences and concerns regarding hypertension management. Guidelines on hypertension lack consensus on how to treat older people without previous cardiovascular disease (CVD). This asks for explicit consideration of patient preferences in decision making.

Targeted gene therapy in human-induced pluripotent stem cells from a patient with primary hyperoxaluria type 1 using CRISPR/Cas9 technology.

Primary hyperoxaluria type 1 (PH1) is an inherited metabolic disorder caused by a deficiency of the peroxisomal enzyme alanine-glyoxylate aminotransferase (AGT), which leads to overproduction of oxalate by the liver and results in urolithiasis, nephrocalcinosis and renal failure. The only curative treatment for PH1 is combined liver and kidney transplantation, which is limited by the lack of suitable organs, significant complications, and the life-long requirement for immunosuppressive agents to maintain organ tolerance. Hepatocyte-like cells (HLCs) generated from CRISPR/Cas9 genome-edited human-induced pluripotent stem cells would offer an attractive unlimited source of autologous gene-corrected liver cells as an alternative to orthotopic liver transplantation (OLT).
