Resilience: Biological Basis and Clinical Significance - A Perspective Report from the International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force.

The Resilience is a construct receiving growing attention from the scientific community in geriatrics and gerontology. Older adults show extremely heterogeneous (and often unpredictable) responses to stressors. Such heterogeneity can (at least partly) be explained by differences in resilience (i.e., the capacity of the organism to cope with stressors). The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force met in Boston (MA,USA) on April 20, 2022 to discuss the biological and clinical significance of resilience in older adults. The identification of persons with low resilience and the prompt intervention in this at-risk population may be critical to develop and implement preventive strategies against adverse events. Unfortunately, to date, it is still challenging to capture resilience, especially due to its dynamic nature encompassing biological, clinical, subjective, and socioeconomic factors. Opportunities to dynamically measure resilience were discussed during the ICFSR Task Force meeting, emphasizing potential biomarkers and areas of intervention. This article reports the results of the meeting and may serve to support future actions in the field.

Challenges in the Development of Drugs for Sarcopenia and Frailty - Report from the International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force.

Sarcopenia and frailty represent two burdensome conditions, contributing to a broad spectrum of adverse outcomes. The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force met virtually in September 2021 to discuss the challenges in the development of drugs for sarcopenia and frailty. Lifestyle interventions are the current mainstay of treatment options in the prevention and management of both conditions. However, pharmacological agents are needed for people who do not respond to lifestyle modifications, for those who are unable to adhere, or for whom such interventions are inaccessible/unfeasible. Preliminary results of ongoing trials were presented and discussed. Several pharmacological candidates are currently under clinical evaluation with promising early results, but none have been approved for either frailty or sarcopenia. The COVID-19 pandemic has reshaped how clinical trials are conducted, in particular by enhancing the usefulness of remote technologies and assessments/interventions.

The authors apologize for a typing error that occurred in the September 2020 article that changes the meaning of a sentence. Correction: Page 921, right column, 2nd paragraph, line 8, change «match» to «watch» so it reads, «Primary care providers should watch for frailty development due to physical inactivity during the COVID-19 pandemic (47).» In addition, the author listed as “C.

Metabolic and liver alterations impact on the severity of SARS-COV2 disease

Background: SARS-COV2 is a threatful viral disease which can evolve into respiratory failure but identification of risk factors for progression towards severe forms is still ongoing During infection impairment of liver function tests has been frequently reported and evidence of the negative impact of metabolic alterations on the clinical course are emerging, mainly evaluated in Asiatic populations Aim: to define the prognostic role of metabolic disease and liver damage on SARS-COV2 severity in a cohort of Italian patients Methods: All patients with confirmed COVID-19 infection admitted to low-intensity care COVID Units between March and April 2020 were enrolled Severe SARS-COV2 infection was defined according to International consensus requiring intensive respiratory support (CPAP/orotracheal intubation) All data were collected at admission Results: 382 patients were enrolled, mean age was 65±17 ys and 60% were male Mean BMI was 27±5 kg/m2 (61% overweight and 25% obese), prevalence of T2DM 17%, hypertension 44%, dyslipidemia 29% At admission 39% and 40% of patients had increased ALT and GGT levels, respectively Median hospitalization stay was 14 days (IQR 8-24), with 30% of patients experiencing severe SARS-COV2 infection and mortality in 14% of overall cases Subjects with severe infection presented higher prevalence of male sex (68% vs 56%, p=0 03), T2DM (25% vs 14%, p=0 01), dyslipidemia (36% vs 26%, p=0 05) and increased ALT (53% vs 32%, p<0 001) and GGT (53% vs 34%, p=0 01) levels at admission In multivariate analysis (adjusted for age, sex, T2DM, dyslipidemia, increased ALT and GGT at admission and SARS-COV2 therapy), T2DM (OR 3 1, 95%CI 1 6-6 0;p=0 001), dyslipidemia (OR 1 9, 95%CI 1 1-3 3;p=0 03), and increased ALT (OR 4 7, 95%CI 2 5- 9 0;p<0 001) and GGT (OR 2 0, 95%CI 1 2-3-3;p=0 009), resulted associated with high risk of more severe SARSCOV2 disease Interestingly, in patients with both T2DM and dyslipidemia, this risk was further increased (OR 5 2, 95%CI 2 1-12 6;p<0 001) Conclusion: We confirm that liver involvement is common during SARS-COV2 infection and it is a negative prognostic factor although it is not clear whether it precedes or follows, the severity of clinical course In addition, the risk of severe form of respiratory distress is increased by metabolic alterations, and the more numerous the alterations, the higher the risk.

COVID-19 and Intrinsic Capacity.

The SARS-CoV-2 infection is particularly associated with negative outcomes (i.e., serious disease, death) in frail older people, independently of where they live. Furthermore, the period of pandemic (with its lockdowns, social distancing, fragmentation of care…) has significantly changed the environment in which older people live. It is likely that, when the pandemic will be over, an acceleration of the aging process will be observed for many persons, independently of whether they have been infected or not by the SARS-CoV-2. The World report on ageing and health, published by the World Health Organization, proposes the concept of intrinsic capacity (i.e., the composite of all the physical and mental capacities of the individual) as central for healthy ageing. The routine assessment of biological age through constructs such as intrinsic capacity might have allowed a better understanding of the functional trajectories and vulnerabilities of the individual, even during a catastrophic event as the one we are currently living. In the present article, we describe how COVID-19 has affected the persons' intrinsic capacity, and how the wide adoption of the intrinsic capacity model may support the modernization of our systems and bring them closer to the individual.

Nutritional Considerations in Frail Older Patients with COVID-19.

The COVID-19 pandemic is posing an unprecedented challenge to healthcare systems worldwide. Older adults, which frequently present multiple chronic comorbidities, are more susceptible to COVID-19 and experience more likely negative outcomes, in terms of disease severity and mortality. However, chronological age per se may not entirely explain the dramatic scenario described among the frailest and oldest persons. Comorbidities and functional status may indeed play a relevant role. Patients at high risk of adverse clinical outcomes in COVID-19 infection are the same at risk of malnutrition, namely older adults and multimorbid individuals. In fact, COVID-19 can negatively impact on nutritional status, both in patients admitted to the hospital with the most severe manifestations of the infection, as well as in those who experience milder/asymptomatic forms of the disease. Despite being quite difficult in these emergency circumstances, nutritional status needs to be assessed in all COVID-19 patients upon admission and during hospital stay. Early nutritional support should be guaranteed in order to improve several malnutrition-related adverse outcomes. The evaluation of the nutritional status is today even more crucial than in normal times given the delicate status of older patients with COVID-19.
