Family Size across the Life Course and Cognitive Decline in Older Mexican Adults.

Objectives: A growing body of research has identified associations between family size and cognition in older adults. These studies largely focus on older adults' own fertility history instead of sibship size, defined as one's number of siblings. Sibship size may impact cognitive development during early childhood, creating differences that may persist into late-life.

Perioperative Venous Thromboembolism Prophylaxis in Orthopedic Trauma: A Practical Review.

Background: Orthopedic trauma patients are at high risk for venous thromboembolic (VTE) complications. Despite this, VTE prophylaxis is often held peri-operatively out of concern for increased bleeding and associated complications. This review's purpose is to examine guidelines and studies on withholding prophylactic anticoagulation peri-operatively.

Cardiac MRI Evaluation of Heart Failure and Cardiomyopathies.

Cardiac magnetic resonance imaging (CMR) is an exciting noninvasive imaging modality with increasing utilization in the field of cardiovascular medicine. In conjunction with echocardiogram, computed tomography, and invasive therapies, CMR has provided exceptional capability to further evaluate complex clinical cardiac conditions. CMR provides both anatomical and physiological information of a variety of tissue types, without the need for ionizing radiation.

Diagnostic Feasibility of Cardiac PET CT in the Evaluation of Inflammatory, Infectious, and Malignant Heart Disease.

Cardiac Positron Emission Tomography (PET) is a power- ful imaging tool with diverse applications in the detection and diagnosis of various cardiac conditions, including inflammatory, infectious, and neoplastic processes. Using the radiotracer 18F-fluorodeoxyglucose (18F-FDG), cardiac PET enables the identification of cardiac involvement in diseases such as sarcoidosis and severe infections affecting the heart tissue. Additionally, 18F-FDG PET is valuable in the evaluation of cardiac masses, helping to assess their metabolic activity and potential malignancy.

Diagnostic Feasibility and Accuracy of Cardiac Positron Emission Tomography (PET) in the Evaluation of Ischemic Heart Disease.

Cardiac Positron Emission Tomography (PET) can be used for the assessment of myocardial perfusion. Compared to other cardiac imaging techniques, notably Single Photon Emission Computer Tomography (SPECT), cardiac PET offers superior image resolution, higher accuracy, quantitative measures of myocardial perfusion, lower radiation exposure, and shorter image acquisition time. However, PET tends to be costlier and less widely available than SPECT due to the specialized equipment needed for generating the necessary radiotracers.

Which Test is Best for Pain in the Chest?

Chest pain is one of the most common chief complaints seen in both the emergency department (ED) and primary care settings.1,2 It is estimated that 20-40% of the general population will suffer from chest pain at some point throughout their lives.3 Interestingly although obstructive coronary artery disease (CAD) prevalence has declined, chest pain as a presenting symptom has become increasingly common over the last decade.

The eyes have it: Alcohol-induced eye movement impairment and perceived impairment in older adults with and without alcohol use disorder.

Background: While alcohol has been shown to impair eye movements in young adults, little is known about alcohol-induced oculomotor impairment in older adults with longer histories of alcohol use. Here, we examined whether older adults with chronic alcohol use disorder (AUD) exhibit more acute tolerance than age-matched light drinkers (LD), evidenced by less alcohol-induced oculomotor impairment and perceived impairment.

Method: Two random-order, double-blinded laboratory sessions with administration of alcohol (0.

A Commitment to Gender Equity in Medicine: An American Medical Women's Association Position Paper.

The American Medical Women's Association (AMWA) highlights the ongoing gender inequities in the medical profession, particularly in pay, leadership roles, workplace treatment, and work-life integration. To present evidence of gender disparities in medicine, analyze their root causes, and propose strategies for fostering a more equitable and inclusive environment. Despite progress, women physicians continue to face significant disparities, including lower salaries, underrepresentation in leadership roles, and discrimination.

Quantifying the ability of the CFH group as a hydrogen bond donor.

The CFH group can act as a hydrogen bond donor, serving as a potential surrogate for OH or SH groups but with a weaker hydrogen bond donation ability. Here, we describe a series of CFH group-containing moieties that facilitate hydrogen bond interactions. We survey hydrogen bond donation ability using several established methods, including H NMR-based hydrogen bond acidity determination, UV-vis spectroscopy titration with Reichardt's dye, and H NMR titration using tri--butylphosphine oxide as a hydrogen bond acceptor.

One state's journey with a reflective supervision professional development series: Development, implementation, and adaptation.

Reflective supervision (RS) has been viewed as best practice and is therefore incorporated-and often mandated-as a key feature of many relationship-based infant and early childhood serving programs. To promote the implementation of high-quality RS for infant and early childhood professionals, it is critical that a focus is placed on how infant and early childhood professionals are trained to build RS capacities. To this end, we describe Rhode Island, United States's journey developing, implementing, and iteratively adapting an RS professional development series.

Decoherence and vibrational energy relaxation of the electronically excited PtPOP complex in solution.

Understanding the ultrafast vibrational relaxation following photoexcitation of molecules in a condensed phase is essential to predict the outcome and improve the efficiency of photoinduced molecular processes. Here, the vibrational decoherence and energy relaxation of a binuclear complex, [Pt2(P2O5H2)4]4- (PtPOP), upon electronic excitation in liquid water and acetonitrile are investigated through direct adiabatic dynamics simulations. A quantum mechanics/molecular mechanics (QM/MM) scheme is used where the excited state of the complex is modeled with orbital-optimized density functional calculations while solvent molecules are described using potential energy functions.
