Background: Currently recognized types of amyloidosis include primary, familial and secondary, each of which may affect the heart. There may be differences in the heart response to the deposition of amyloid fibrils in these three forms of the disease.
Materials And Methods: Over a period of 10 years (1985-95), 28 consecutive patients with primary, 11 with secondary and 17 with familial amyloidosis were studied at the Departments of Cardiology of Laiko and Hammersmith Hospitals. The diagnosis of amyloidosis was confirmed by biopsies of subcutaneous fat, rectum, kidney, bone marrow, gum or sural nerve. Diagnosis of cardiac involvement was based on typical electrocardiographic and echocardiographic findings.
Results: The left ventricular fractional shortening (%) was reduced in primary compared with familial or secondary amyloidosis (29.8 +/- 10.2 vs. 36.2 +/- 6.5 vs. 36 +/- 5.9, P < 0.05). The transmitral flow velocity pattern was compatible with abnormal relaxation in most patients in the three groups [primary 16 (57%), familial 11 (64. 7%), secondary 6 (54.5%), P = NS]. Right ventricular systolic dysfunction (right ventricular dP/dt < 220 mmHg s-1 or tricuspid annulus systolic excursion < 10 mm) was present in 8 (28.6%), 2 (11. 8%) and 0 patients. Patients with primary amyloidosis were followed up for 15 +/- 6 months. There were 12 deaths, and repeat echocardiography in the survivors revealed a significant deterioration of left ventricular systolic function (fractional shortening = 23.6% +/- 8.8%, P < 0.05 vs. baseline).
Conclusion: Primary amyloidosis is characterized by more severe cardiac involvement than the familial or secondary amyloidosis and has an ominous course.

Precision medicine involves a paradigm shift toward personalized data-driven clinical decisions. The concept of a medical "digital twin" has recently become popular to designate digital representations of patients as a support for a wide range of data science applications. However, the concept is ambiguous when it comes to practical implementations.

Background: Health is the cornerstone of individual well-being and a vital factor in socioeconomic development. In an increasingly digitalized world, digital literacy has emerged as one of the indispensable abilities, which not only pertains to an individual's capacity to acquire, analyze, evaluate, and utilize information but also profoundly influences their health behaviours, health decisions, and overall well-being. This paper uses the 2020 China Family Panel Studies (CFPS) data to explore digital literacy's impact on individuals' health.

The Alkbh7 protein, a member of the Alkylation B (AlkB) family of dioxygenases, plays a crucial role in epigenetic regulation of cellular metabolism. This paper focuses on the NMR backbone resonance assignment of Alkbh7, a fundamental step in understanding its three-dimensional structure and dynamic behavior at the atomic level. Herein, we report the backbone H, N, C chemical shift assignment of the full-length human Alkbh7.

Introduction: Schools are an important setting for supporting children's development of food literacy, but minimal research has assessed which strategies are most suitable for school nutrition education. The Foodbot Factory intervention, consisting of serious game (ie, a digital game designed for education) and curriculum-based lesson plans, was developed to support teachers and children ages 8-12 with nutrition education. Pilot data have demonstrated that Foodbot Factory can significantly improve children's nutrition knowledge, but it has not yet been evaluated in classrooms.

Study Design: A time-lapsed, quasi-experimental design in which control participants were enrolled and then intervention participants enrolled. Data collection occurred at three timepoints: NICU admission (AD), discharge (DC), and 30 days post-discharge (DC+30).
