Real-life reliability of plasma pTau181, Aβ/Aβ, and pTau181/Aβ measured by Lumipulse G600II in predicting cerebrospinal fluid amyloid status.

Background: Alzheimer's disease (AD) is the most common neurodegenerative dementia, with diagnosis traditionally reliant on clinical criteria. Cerebrospinal fluid (CSF) biomarkers like pTau181 and Aβ/Aβ ratio significantly improve diagnostic accuracy but are invasive. Plasma biomarkers measured by automated assays offer a non-invasive alternative.

Metabolic dysfunction-associated steatotic liver disease prevalence and risk factors in inflammatory bowel disease in tertiary center.

Objective: The aim of this study was to evaluate the prevalence and risk factors related to metabolic dysfunction-associated steatotic liver disease in inflammatory bowel disease patients.

Methods: This is a cross-sectional study conducted on adults with inflammatory bowel disease from 2019 to 2021. Metabolic dysfunction-associated steatotic liver disease encompasses patients with steatosis and at least one cardiometabolic risk factor.

Restoring consciousness with pharmacologic therapy: Mechanisms, targets, and future directions.

Severe brain injury impairs consciousness by disrupting a broad spectrum of neurotransmitter systems. Emerging evidence suggests that pharmacologic modulation of specific neurotransmitter systems, such as dopamine, promotes recovery of consciousness. Clinical guidelines now endorse the use of amantadine in individuals with traumatic disorders of consciousness (DoC) based on level 1 evidence, and multiple neurostimulants are used off-label in clinical practice, including methylphenidate, modafinil, bromocriptine, levodopa, and zolpidem.

Point-of-care isothermal nucleic acid amplification tests: progress and bottlenecks for extraction-free sample collection and preparation.

Introduction: Suitable sample collection and preparation methods are essential to enable nucleic acid amplification testing at the point of care (POC). Strategies that allow direct isothermal nucleic acid amplification testing (iNAAT) of crude sample lysate without the need for nucleic acid extraction minimize time to result as well as the need for operator expertise and costly infrastructure.

Areas Covered: The authors review research to understand how sample matrix and preparation affect the design and performance of POC iNAATs.

Asymmetrical Diketopyrrolopyrrole Derivatives with Improved Solubility and Balanced Charge Transport Properties.

The diketopyrrolopyrrole (DPP) unit represents one of the building blocks more widely employed in the field of organic electronics; in most of the reported DPP-based small molecules, this unit represents the electron acceptor core symmetrically coupled to donor moieties, and the solubility is guaranteed by functionalizing lactamic nitrogens with long and branched alkyl tails. In this paper, we explored the possibility of modulating the solubility by realizing asymmetric DPP derivatives, where the molecular structure is extended in just one direction. Four novel derivatives have been prepared, characterized by a common dithyenil-DPP fragment and functionalized on one side by a thiophene unit linked to different auxiliary electron acceptor groups.

Optimal Timing for Resumption of Anticoagulation After Intracranial Hemorrhage in Patients With Mechanical Heart Valves.

Background: Anticoagulation in patients with intracranial hemorrhage (ICH) and mechanical heart valves is often held for risk of ICH expansion; however, there exists a competing risk of acute ischemic stroke (AIS). Optimal timing to resume anticoagulation remains uncertain.

Methods And Results: We retrospectively studied patients with ICH and mechanical heart valves from 2000 to 2018.

Charting public views on the meaning of illness severity.

Background: Illness severity is a central principle in multiple priority-setting frameworks, yet there is a paucity of research on public views regarding the meaning of illness severity. This study builds on the findings of a Q methodology study with members of the public that identified four general viewpoints on the meaning of illness severity. Here, we investigate the support for those viewpoints among the Norwegian population.

Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies.

When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip.

Short-Term (6 Months or Less) Pain in Cemented versus Cementless Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.

Background: Cementless total knee arthroplasty (TKA) has increased in popularity to potentially improve survivorship. Radiostereometric studies demonstrate increased component migration during the first 3 to 6 months in cementless constructs, generating concern for increased postoperative pain during early osseointegration. The purpose of this study was to evaluate short-term (≤ 6 months) pain and function in cemented versus cementless TKA.

Changes in social norms during the early stages of the COVID-19 pandemic across 43 countries.

The emergence of COVID-19 dramatically changed social behavior across societies and contexts. Here we study whether social norms also changed. Specifically, we study this question for cultural tightness (the degree to which societies generally have strong norms), specific social norms (e.

Single-tube four-target lateral flow assay detects human papillomavirus types associated with majority of cervical cancers.

Isothermal nucleic acid amplification methods have many advantages for use at the point of care. However, there is a lack of multiplexed isothermal amplification tests to detect multiple targets in a single reaction, which would be valuable for many diseases, such as infection with high-risk human papillomavirus (hrHPV). In this study, we developed a multiplexed loop-mediated isothermal amplification (LAMP) reaction to detect the three most common hrHPV types that cause cervical cancer (HPV16, HPV18, and HPV45) and a cellular control for sample adequacy.

Posterior tibial slope considered as an important addition to the CPAK classification system.

Introduction: Coronal Plane Alignment of the Knee (CPAK), is an informative way to classify native knee alignment types, but does not consider posterior tibial slope, an important variable in knee kinematics. We hypothesized that tibial slope would have a significant effect on knee kinematics and warrant consideration in addition to the CPAK system.

Methods: We examined 335 adult patients with osteoarthritis receiving total knee arthroplasty.

Premature Death as a Normative Concept.

The practical goal of preventing premature death seems uncontroversial. But the term 'premature death' is vague with several, sometimes conflicting definitions. This ambiguity results in several conceptions with which not all will agree.

Evaluation of Medication Exposure on Exacerbation of Disease in Patients With Myasthenia Gravis.

Background And Purpose: In patients with myasthenia gravis (MG), worsening of symptoms poses a risk of respiratory failure which can be precipitated by medication use. Although purported, the risks associated with administration of certain medications are not fully elucidated. Thus, clinical decision support involving a best practice alert was executed to caution providers of drug-disease interactions when ordering a potentially harmful medication.

Intravenous Ganaxolone: Pharmacokinetics, Pharmacodynamics, Safety, and Tolerability in Healthy Adults.

Ganaxolone, a neuroactive steroid anticonvulsant that modulates both synaptic and extrasynaptic γ-aminobutyric acid type A (GABA ) receptors, is in development for treatment of status epilepticus (SE) and rare epileptic disorders, and has been approved in the United States for treatment of seizures associated with cyclin-dependent kinase-like 5 deficiency disorder in patients ≥2 years old. This phase 1 study in 36 healthy volunteers evaluated the pharmacokinetics, pharmacodynamics, and safety of intravenous ganaxolone administered as a (i) single bolus, (ii) infusion, and (iii) bolus followed by continuous infusion. After a single bolus over 2 minutes (20 mg) or 5 minutes (10 or 30 mg), ganaxolone was detected in plasma with a median T of 5 minutes, whereas a 60-minute infusion (10 or 30 mg) or a bolus (6 mg over 5 minutes) followed by infusion (20 mg/h) for 4 hours achieved a median T of approximately 1 and 3 hours, respectively.

Evaluation of Bivalirudin During Adult Extracorporeal Membrane Oxygenation: A Retrospective Characterization of Dosing, Efficacy and Bleeding.

Although heparin is the current standard anticoagulant during venoarterial (VA) and venovenous (VV) extracorporeal membrane oxygenation (ECMO), factors including heparin-induced thrombocytopenia, heparin resistance and drug shortages necessitate alternative anticoagulants such as direct thrombin inhibitors. The aim was to characterize dosing, safety, and efficacy of bivalirudin during ECMO support. This retrospective single-center study included 24 adults on ECMO support who received ≥6 hours of bivalirudin.

A novel tailed primer nucleic acid test for detection of HPV 16, 18 and 45 DNA at the point of care.

Cervical cancer is a leading cause of death for women in low-resource settings despite being preventable through human papillomavirus (HPV) vaccination, early detection, and treatment of precancerous lesions. The World Health Organization recommends high-risk HPV (hrHPV) as the preferred cervical cancer screening strategy, which is difficult to implement in low-resource settings due to high costs, reliance on centralized laboratory infrastructure, and long sample-to-answer times. To help meet the need for rapid, low-cost, and decentralized cervical cancer screening, we developed tailed primer isothermal amplification and lateral flow detection assays for HPV16, HPV18, and HPV45 DNA.

[Ten-year survival after off-pump coronary artery bypass grafting compared with traditional bypass grafting].

Background: Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined.

Aim: To compare 10-year survival of isolated OPCAB versus CABG with CPB.

Material And Methods: Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital.

Signalling need for care: a neglected functional role of medical treatment.

Background And Objectives: While the primary goals of medical treatment are typically to shorten illness or relieve symptoms, we explore the idea that an important additional goal for some patients is to communicate their needs. Drawing on , we argue that undergoing treatments can help patients legitimize their illness and thereby enable access to crucial support during convalescence.

Methods And Results: Four pre-registered within-subjects experiments ( = 874) show that participants are more inclined to provide care to people who undergo treatment, especially when that treatment is painful.

Adherence to SARS-CoV-2 Vaccination Recommendations among Patients with Substance Use Disorders: A Cross-Sectional Study in Rome, Italy.

Adherence to vaccination recommendations is a challenge for national immunization programs. We quantified adherence to COVID-19 vaccination recommendations in people with substance use disorders (SUDs) attending an outpatient addiction center in Rome, Italy; we investigated the determinants of adherence, and also analyzed patient risk perception and compliance with preventive measures. A multivariable logistic regression model identified predictors of adherence to vaccination recommendations, with statistical validity tested by estimating adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

Multidisciplinary Approach to Sedation and Early Mobility of Intubated Critically Ill Neurologic Patients Improves Mobility at Discharge.

Background And Purpose: Over-sedation may confound neurologic assessment in critically ill neurologic patients and prolong duration of mechanical ventilation (MV). Decreased sedative use may facilitate early functional independence when combined with early mobility. The objective of this study was to evaluate the impact of a stepwise, multidisciplinary analgesia-first sedation pathway and early mobility protocol on medication use and mobility in the neuroscience intensive care unit (ICU).
