Frailty after COVID-19: The wave after?

Association between inflammatory markers, body composition and frailty in home-dwelling elderly: an 8-year follow-up study

Frailty has been linked to inflammation and changes in body composition, but the findings are inconsistent. To explore this, we used the Frailty Index (FI) definition to (1) investigate the association between levels of inflammatory markers (baseline) and change in FI score after 8 years of follow-up and (2) investigate the longitudinal associations between inflammatory markers, body composition, and frailty. Home-dwelling elderly (≥ 70 years) were invited to participate in the study and re-invited to a follow-up visit 8 years later. This study includes a total of 133 participants. The inflammatory markers included were high-sensitive C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), and glycoprotein acetyls (Gp-acetyls). We used the body composition markers fat mass, fat-free mass, and waist circumference. The FI score consisted of 38 variables. Additional clinical assessments such as blood pressure and body mass index (BMI), as well as information about daily medications, were collected at both visits. Linear regression model and Spearman's rank correlation were used to investigate associations. We showed that the FI score increased after 8 years, and participants with higher hs-CRP levels at baseline had the largest change in the FI score. Changes in fat mass were significantly correlated with changes in hs-CRP and IL-6, and changes in waist circumference were significantly correlated with changes in TNF-α. The use of drugs increased during the 8 years of follow-up, which may have attenuated the associations between inflammation and frailty. However, elevated concentrations of hs-CRP in the elderly may be associated with an increased risk of frailty in subsequent years.

Frailty as a Predictor of COVID-19 Mortality in the South Indian Population: An Observational Study

Background Frailty is a clinical syndrome characterized by diminished strength, endurance, and physiological function that significantly increases vulnerability to adverse health outcomes, including infections. In the context of COVID-19, frailty has emerged as a critical risk factor for severe disease, complications, and mortality, particularly in older adults. The severity and fatality rates among the geriatric group were notably high, as the virus's pathogenesis, marked by prolonged inflammation, contributed to increased morbidity and mortality in this age group. The study was conducted to explore the role of frailty in influencing mortality among the elderly affected by COVID-19. Objective The objective of this study was to identify the association between frailty and mortality in COVID-19-affected elderly patients.  Methods We conducted a prospective observational study among elderly patients who tested positive for COVID-19 and received treatment in a tertiary care hospital. Data were collected from 250 patients from March 2021 to December 2021. Lab parameters, the necessity for mechanical ventilation, the need for oxygen use, and the number of days of hospital stay were recorded. The Clinical Frailty Score (CFS) was used to evaluate frailty. The chi-square test with Fisher's exact test was used to assess the association between frailty and mortality in the data set. Multivariate binary logistic regression was employed to identify the most significant predictors of mortality. Results Among the 250 patients, 159 (63.6%) survived and were discharged, while 91 (36.4%) succumbed to the illness. Fifty-eight patients were not identified as frail, and there were no deaths in the group. On the contrary, among the 192 COVID-positive patients who were identified as frail, 91 (47.4%) patients died, and 101 (52.6%) patients were alive. This depicted the association between frailty and mortality in COVID-19 geriatric patients. While assessing comorbidities, malignancy (53.3%, p-value = 0.009) and chronic kidney disease (CKD) (43.3%) had a significant association with mortality. Symptoms like fever (43.6%), dyspnea (68.6%), myalgia (20%), and altered sensorium (84%) showed a strong correlation with mortality (p<0.001). Frailty was a significant predictor of mortality, with 47.4% of frail patients not surviving (p<0.001). Biochemical markers including leukocytosis (64.8%), neutrophilia (65.3%), eosinopenia (66.9%), anemia (57.8%), hypoalbuminemia (63.5%), hypoproteinemia (70.1%), elevated alanine aminotransferase (ALT) (66%), aspartate aminotransferase (AST) (65.2%), alkaline phosphatase (ALP) (67.5%), elevated creatinine (68.9%), hypernatremia (100%), hyperkalemia (80%), and elevated D-dimer (44.7%) were all significantly linked to mortality. Additionally, patients requiring oxygen (65%), ventilation (96.8%), or bilevel positive airway pressure (BiPAP) (77.8%) had higher mortality rates. A shorter length of hospital stay was also associated with increased mortality (24%). Conclusion Frailty, combined with certain comorbidities such as cancer and CKD, along with various clinical and biochemical markers, played a significant role in predicting mortality among geriatric COVID-19 patients. Incorporating frailty assessments into routine evaluations for elderly COVID-19 survivors could be beneficial. Early detection and focused management of these high-risk factors are essential for improving outcomes in frail patients within tertiary care settings.

Management of patients with neurological diseases considering post-pandemic coronavirus disease 2019 (COVID-19) related risks and dangers - An updated European Academy of Neurology consensus statement

BACKGROUND AND PURPOSE

In October 2020, the European Academy of Neurology (EAN) consensus statement for management of patients with neurological diseases during the coronavirus disease 2019 (COVID-19) pandemic was published. Due to important changes and developments that have happened since then, the need has arisen to critically reassess the original recommendations and address new challenges.

METHODS

In step 1, the original items were critically reviewed by the EAN COVID-19 Task Force. In addition, new recommendations were defined. In step 2, an online survey with the recommendations forged in step 1 was sent to the Managing Groups of all Scientific and Coordinating Panels of EAN. In step 3, the final set of recommendations was made.

RESULTS

In step 1, out of the original 36 recommendations, 18 were judged still relevant. They were edited to reflect the advances in knowledge and practice. In addition, 21 new recommendations were formulated to address the new knowledge and challenges. In step 2, out of the 39 recommendations sent for the survey, nine were approved as they were, whilst suggestions for improvement were given for the rest. In step 3, the recommendations were further edited, and some new items were formed to accommodate the participants' suggestions, resulting in a final set of 41 recommendations.

CONCLUSION

This revision of the 2020 EAN Statement provides updated comprehensive and structured guidance on good clinical practice in people with neurological disease faced with SARS-CoV-2 infection. It now covers the issues from the more recent domains of COVID-19-related care, vaccine complications and post-COVID-19 conditions.

Changes in frailty and lifestyle among community-dwelling older adults: A two-point cross-sectional study during and after the COVID-19 pandemic in Japan

We aimed to verify the characteristics of lifestyles and frailty among older adults during and after the COVID-19 pandemic. This two-point cross-sectional study conducted a baseline survey (BL) in 2020 and a follow-up survey (FU) in 2023 with community-dwelling individuals aged ≥65 years in Japan. The 700 and 572 participants in the BL and FU were analyzed. We compared frailty occurrence and lifestyle characteristics between both surveys. In the BL and FU, 38.3 %, 52.4 %, and 9.3 % and 29.4 %, 59.4 %, and 11.2 % of the individuals were classified as robust, pre-frail, and frail, respectively, showing a significant decrease in the number of robust, and an increase in the number of pre-frail. A significant decrease in dietary intake was observed among robust individuals in the FU, with an overall significant decrease in communication opportunities in the BL. Therefore, lifestyle changes due to infection control measures may have a delayed impact on frailty.

Secondary infections and long-term outcomes among hospitalized elderly and non-elderly patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and treated with baricitinib: a comparative study from the national centre of Hungary

Baricitinib is considered a first-line treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected adult patients with an associated cytokine storm syndrome (CSS). Our objective was to compare rates of secondary infections and long-term outcomes of elderly and non-elderly patients who received baricitinib for COVID-19. We conducted a single-centre observational study between November 2020 and September 2023, focusing on hospitalized adult SARS-CoV-2 patients with CSS, categorized as elderly (≥ 65 years) and non-elderly (< 65 years). Enrolment, severity stratification, and diagnosis of infectious complications followed predefined criteria. Outcomes of all-cause mortality and rates of non-severe and severe secondary infections were assessed at 1-year post-treatment initiation. Kaplan-Meier analysis was performed for survival analysis. In total, 490 patients were enrolled (median age 65 ± 23 (21-100) years (years, median ± IQR, min-max); 49.18% elderly; 59.59% male). Elderly patients were admitted to the hospital significantly earlier (7 ± 5 days vs. 8 ± 4 days; p = 0.02), experienced a higher occurrence of severe COVID-19 (121/241, 50.21% vs. 98/249, 39.36%; p = 0.02), and required the use of non-invasive ventilation at baseline (167/225, 74.22% vs. 153/236, 64.83%; p = 0.03). At 1 year, all-cause mortality was significantly higher in the elderly subgroup (111/241, 46.06% vs. 29/249, 11.65%; p < 0.01). At 90 days and 1 year, rates of any severe secondary infection were also more prevalent among the elderly (56/241, 23.24% vs. 37/249 14.86%; p = 0.02 and 58/241, 24.07% vs. 39/249, 15.66%; p = 0.02). In conclusion, elderly SARS-CoV-2-infected patients experience a more severe clinical course, higher secondary infection rates, and increased risk for long-term mortality, regardless of immunomodulatory therapy.

Lingering effects of COVID-19 in the care of perioperative patients

PURPOSE OF REVIEW

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can lead to organ dysfunction and clinical symptoms beyond the acute infection phase. These effects may have significant implications for the management of perioperative patients. The purpose of this article is to provide a systems-based approach to the subacute and chronic effects of SARS-CoV-2 that are most relevant to anesthesiology practice.

RECENT FINDINGS

In 2024, COVID-19 remains a concern for anesthesiologists due ongoing new infections, evolving viral strains, and relatively low rates of booster vaccination in the general population. A growing body of literature describes the post-COVID-19 syndrome in which patients experience symptoms more than 12 weeks after acute infection. Recent literature describes the lingering effects of SARS-CoV-2 infection on all major organ systems, including neurologic, pulmonary, cardiovascular, renal, hematologic, and musculoskeletal, and suggests an increased perioperative mortality risk in some populations.

SUMMARY

This review offers anesthesiologists an organ system-based approach to patients with a history of COVID-19. Recognizing the long-term sequelae of SARS-CoV-2 infection can help anesthesiologists to better evaluate perioperative risk, anticipate clinical challenges, and thereby optimize patient care.
