Article Synopsis
  • - The study investigates the effectiveness of a new 3D ultrasound (3D-US) technique for measuring muscle volume in older adults, particularly in relation to sarcopenia, a condition characterized by muscle loss.
  • - Researchers found that 3D-US measurements demonstrated better concordance with total appendicular skeletal muscle mass (ASMM) compared to traditional 2D ultrasound (2D-US), with high reliability in 3D-US measurements.
  • - The results suggest that using 3D-US can offer significant advantages in assessing muscle volume and strength, supporting its potential as a reliable tool in geriatric rehabilitation settings.

Reliability of muscle thickness assessed in B-mode ultrasound has been confirmed in adults but remains a less direct assessment of muscle mass than muscle volume (MV). The aim of this prospective monocentric study was to assess the interday reliability of MV determined by the 2D-panoramic ultrasound in older hospitalized patients.Ten participants hospitalized in geriatric ward (mean age = 84) underwent 2 sessions of panoramic ultrasound scanning 1 week apart for MV assessment and DXA for leg lean mass (LLM) assessment when it was possible.

Introduction: Increasing evidence supports the implementation of geriatric assessment in the workup of older patients with aortic stenosis (AS). In 2012, an online European survey revealed that geriatricians were rarely involved in the assessment of candidates for transcatheter aortic valve implantation (TAVI). After a "call to action" for early involvement of geriatricians in AS evaluation, the survey was repeated in 2022.

Article Synopsis
  • Aortic valve calcification (AVC) was studied in patients with bioprosthetic valves to assess its impact on patient prognosis.
  • In a study of 361 patients who had valve replacements, AVC was found to be significantly higher in those with structural valve degeneration (SVD).
  • The results indicate that AVC greater than 100 Agatston units is correlated with worse health outcomes and increased risk of mortality and cardiovascular events, making CT scans a valuable tool for evaluation.

Aims: The heart failure (HF) prognosis in older patients remains poor with a high 5-years mortality rate more frequently attributed to noncardiovascular causes. The complex interplay between frailty and heart failure contribute to poor health outcomes of older adults with HF independently of ejection fraction. The aim of this position paper is to propose a practical management of frailty in older patients with heart failure.

Background: Aging is one of the most important prognostic factors increasing the risk of clinical severity and mortality of COVID-19 infection. However, among patients over 75 years, little is known about post-acute functional decline.

Objective: The aim of this study was to identify factors associated with functional decline 3 months after COVID-19 onset, to identify long term COVID-19 symptoms and transitions between frailty statesafter COVID-19 onset in older hospitalized patients.

Article Synopsis
  • The study aimed to determine if diabetes is a risk factor for severe COVID-19 outcomes, independent of age and other health conditions, as diabetes is often seen in older individuals.
  • Conducted as part of the CORONADO initiative, the research matched 2210 COVID-19 patients with and without diabetes by age, sex, and admission date, assessing outcomes like death and the need for invasive mechanical ventilation.
  • Results showed that diabetes patients had higher rates of adverse outcomes within both 7 and 28 days of hospital admission, indicating that diabetes is a significant risk factor for severe COVID-19 complications regardless of age and comorbidity.

Résumé L'amylose cardiaque dite sénile, également dénommée « sauvage », était considérée comme une maladie rare. Actuellement, grâce à des moyens diagnostiques non invasifs et à partir d'études autopsiques, nous estimons la prévalence à environ 10 à 20 % des sujets de plus de 80 ans. De même, l'amylose était un diagnostic sans conséquence thérapeutique, mis à part le traitement de l'insuffisance cardiaque et des troubles de conduction.

Background: Although a familial component of calcific aortic valve stenosis (CAVS) has been described, its heritability remains unknown. Hence, we aim to assess the heritability of CAVS and the prevalence of bicuspid aortic valve among CAVS families.

Methods: Probands were recruited following aortic valve replacement (AVR) for severe CAVS on either tricuspid (TAV) or bicuspid aortic valve (BAV).

Frailty in elderly people is frequent and places a person at increased risk of adverse outcomes, but it is potentially reversible. Easy and quick to complete, the Gérontopôle Frailty Screening Tool (GFST) has been designed for early diagnosis of frail elderly. The answer comes from the GP's impression in front of the patient, guided by six frailty characteristic parameters.

Glucose and sodium tubular reabsorption inhibitors, or gliflozins, are a new therapeutic class. Their novel mechanism of action involves inhibition of a glucose and Na+ reabsorption co-transporter in the renal proximal tubule. They reduce blood glucose levels by reducing renal glucose reabsorption.

Background: For patients with transcatheter aortic valve replacement (TAVR), increased length of stay (LOS) is associated with increased long-term mortality. The main objective of our study was to analyze the association between geriatrics factors and the hospital LOS for older patients undergoing TAVR for severe aortic stenosis.

Methods: This retrospective single-center study included all patients aged ≥75 who underwent TAVR between January 2018 and January 2019.

Background: The Task Force for the diagnosis and management of atrial fibrillation (AF) of the European Society of Cardiology (ESC) published in 2020 the updated Guidelines for the Diagnosis and Management of Atrial Fibrillation with the contribution of the European Heart Rhythm Association (EHRA) of the ESC and the European Association for Cardiothoracic Surgery (EACTS).

Methods And Results: In this narrative viewpoint, we approach AF from the perspective of aging medicine and try to provide the readers with information usually neglected in clinical routine, mainly due to the fact that while the large majority of AF patients in real life are older, frail and cognitively impaired, these are mostly excluded from clinical trials, and physicians' attitudes often prevail over standardized algorithms.

Conclusions: On the basis of existing evidence, (1) opportunistic AF screening by pulse palpation or ECG rhythm strip is cost-effective, and (2) whereas advanced chronological age by itself is not a contraindication to AF treatment, a Comprehensive Geriatric Assessment (CGA) including frailty, cognitive impairment, falls and bleeding risk may assist in clinical decision making to provide the best individualized treatment.

Background: Transcatheter aortic-valve replacement (TAVR) reduces mortality and improves quality of life in patients with severe aortic valve stenosis. One third of patients have no benefit one year after TAVR. Sarcopenia, an age-related loss of skeletal muscle mass, is associated with increased physical disability and mortality.

Article Synopsis
  • Osteoporosis and sarcopenia are common in older adults, especially women 75 and older, and they share similar biological mechanisms; this study examines their relationship specifically in this demographic.
  • The research included 101 Caucasian women, revealing that a significant portion suffered from osteoporosis (72%) and sarcopenia (37%), with 34% affected by both conditions (osteosarcopenia).
  • Findings indicated that fat mass has a protective role against osteosarcopenia, as those with this condition had significantly lower fat mass and BMI, prompting further consideration of how these factors relate to bone health.
