Pharmacist-Led Deprescribing of Aspirin in Older People in an Outpatient Setting.

In 2019, the American College of Cardiology and American Heart Association updated their joint guidelines stating low-dose aspirin should not be used on a routine basis for primary prevention of atherosclerotic cardiovascular disease (ASCVD) among people older than 70 years of age because of increased bleeding risk. In addition to these updated guidelines, a statement released by the US Preventive Services Task Force in April 2022 recommends against the initiation of low-dose aspirin for primary prevention of cardiovascular disease in people 60 years of age or older.² Despite these updated recommendations, aspirin continues to be a common medication older patients take, providing an opportunity for a clinical pharmacist deprescribing intervention.

Preliminary report of transmitted drug resistance to integrase strand chain transfer inhibitors in treatment-naïve HIV infected patients.

Transmitted Resistance exists in a newly diagnosed person who has not yet started their treatment. Our objective was to obtain a profile of HIV-1 resistance to integrase inhibitors in newly diagnosed treatment-naïve patients. Fifty people newly diagnosed with HIV-1 infection who had never received antiretroviral treatment were recruited.

This paper presents DigiHEALTH, a suite of digital solutions for long-term healthy and active aging.

Lip and tongue pressure and the functionality of oro-facial structures in healthy individuals.

Background: With the ageing process changes in the musculature of oro-facial structures take place, consequently there is a reduction in the strength and mobility of the lips, tongue and cheeks.

Objective: The aim of this study was to correlate oro-facial structures and chewing and swallowing functions among a group of senior citizens and young adults and check the influence of lip and tongue pressure of these functions.

Methods: This is an observational, cross-sectional and analytical study.

Fast and versatile platform for pedicle screw insertion planning.

Purpose: Computer-assisted surgical planning methods help to reduce the risks and costs in transpedicular fixation surgeries. However, most methods do not consider the speed and versatility of the planning as factors that improve its overall performance. In this work, we propose a method able to generate surgical plans in minimal time, within the required safety margins and accounting for the surgeon's personal preferences.

TNF-α Affects Signature Cytokines of Th1 and Th17 T Cell Subsets through Differential Actions on TNFR1 and TNFR2.

Tumor necrosis factor (TNF)-α is a pleiotropic cytokine implicated in the etiology of several autoimmune diseases, including rheumatoid arthritis (RA). TNF-α regulates diverse effector functions through the activation of TNF-α receptor (TNFR)1 and TNFR2. Although the detrimental role of this cytokine has been addressed in distinct disease settings, the effects of TNF-α on cytokine production by isolated CD4 T helper type 1 (Th1) and Th17 cells, two T cell subpopulations that contribute to the pathogenesis of RA, have not been completely elucidated.

A Power Tracking Algorithm for Early Detection of Centrifugal Flow Pump Thrombosis.

Logfiles from the HeartWare HVAD System provide operational pump trend data to aid in patient management. Pump thrombosis is commonly associated with increases in the logfile power that may precede the clinical presentation. A Power Tracking algorithm was developed to detect significant deviations in pump power that may be associated with pump thrombus (PT).

HIV-1 resistance patterns to integrase inhibitors in Chilean patients with virological failure on raltegravir-containing regimens.

In this viewpoint we would like to describe our results in terms of resistance pattern in Chilean patients with virological failure (VF) on raltegravir (RAL)-containing-regimens and highlight the need for the concomitant availability of genotypic resistance testing to integrase strand transfer inhibitors (INSTIs) introduction in antiretroviral regimens, particularly in countries in South America. Indeed we found in our study the presence of two or more primary mutations in some of the participants which is associated with cross-resistance to all INSTIs. By using timely genotyping, we could optimally manage these patients, early after detection of VF.

Novel gene variant for congenital hemidysplasia with ichthyosiform erythroderma and limb defects (CHILD) syndrome.

We report a case of a 1-year and 2-month-old girl with clinical features consistent with congenital hemidysplasia with ichthyosis and limb defects syndrome. Sterol analysis from skin flakes revealed increased levels of a mono 4-alpha methyl sterol also seen in plasma as well as the presence of 4-alpha-carboxy-4-methyl-cholest-8(9)-en-3beta-ol and several keto-sterols, which are usually below the limit of detection. This sterol pattern is consistent with abnormal function of the 4-alpha-methylsterol-4-demethylase complex.

Standardization of a colorimetric technique for determination of enzymatic activity of diamine oxidase (DAO) and its application in patients with clinical diagnosis of histamine intolerance.

Background: Diamine Oxidase (DAO) has an essential role for degradation of exogenous histamine in the intestine; thus, histamine intolerance (HI) mainly has been correlated to a low concentration and/or activity of this enzyme. The objective of the study was to standardize a colorimetric technique to measure the enzymatic activity (function) of hDAO to then apply it to a series of 22 patients with a clinical diagnosis of HI.

Methods: For the standardization variables such as volume and type of sample, incubation time, wavelength of maximum absorption, types of substrates, and concentration of oxidized ascorbate were evaluated.

Evolution and clinical adoption of the Autologs system: An automated analysis for enhanced patient management in MCS.

The Medtronic Autologs System allows real-time clinician review of HeartWare HVAD System logfiles, providing supplemental pump data to aid in patient management. In its first year of availability, Autologs generated a 70% increase in logfile submissions, with 73% of all logfile requests being sent to Autologs. Within a month of its launch, Autologs submissions outnumbered the amount of logfiles submitted for manual review.

Assessing metacognitive and help-seeking strategies in schizophrenia: design and psychometric validation of the Versailles Metacognitive Strategies Evaluation Questionnaire.

Objectives: The aim of this study is to design a questionnaire, the Versailles Metacognitive Strategies Evaluation Questionnaire, for assessing the use of metacognitive and help-seeking strategies in three key-domains of impaired daily functioning in schizophrenia. To evaluate its psychometric properties (internal consistency, factor structure, convergent and divergent validity, and stability).

Design: Development of a questionnaire and psychometric validation procedure in patients with schizophrenia compared with healthy controls.

Systemic Sclerosis Patients Present Alterations in the Expression of Molecules Involved in B-Cell Regulation.

The activation threshold of B cells is tightly regulated by an array of inhibitory and activator receptors in such a way that disturbances in their expression can lead to the appearance of autoimmunity. The aim of this study was to evaluate the expression of activating and inhibitory molecules involved in the modulation of B cell functions in transitional, naive, and memory B-cell subpopulations from systemic sclerosis patients. To achieve this, blood samples were drawn from 31 systemic sclerosis patients and 53 healthy individuals.

A short protocol using dexamethasone and monophosphoryl lipid A generates tolerogenic dendritic cells that display a potent migratory capacity to lymphoid chemokines.

Background: Generation of tolerogenic dendritic cells (TolDCs) for therapy is challenging due to its implications for the design of protocols suitable for clinical applications, which means not only using safe products, but also working at defining specific biomarkers for TolDCs identification, developing shorter DCs differentiation methods and obtaining TolDCs with a stable phenotype. We describe here, a short-term protocol for TolDCs generation, which are characterized in terms of phenotypic markers, cytokines secretion profile, CD4+ T cell-stimulatory ability and migratory capacity.

Methods: TolDCs from healthy donors were generated by modulation with dexamethasone plus monophosphoryl lipid A (MPLA-tDCs).

Enrichment of human ESC-derived multipotent mesenchymal stem cells with immunosuppressive and anti-inflammatory properties capable to protect against experimental inflammatory bowel disease.

Human ESCs provide access to the earliest stages of human development and may serve as an unlimited source of functional cells for future cell therapies. The optimization of methods directing the differentiation of human embryonic stem cells (hESCs) into tissue-specific precursors becomes crucial. We report an efficient enrichment of mesenchymal stem cells (MSCs) from hESCs through specific inhibition of SMAD-2/3 signaling.
