Can EWGSOP2 and SDOC Definitions of Sarcopenia Identify Functional Muscle Quality?

Objectives: To compare the European Working Group on Sarcopenia in Older People (EWGSOP2) and the Sarcopenia Definition and Outcomes Consortium (SDOC) in identifying muscle quality indexes (MQI) and lower limb muscle performance in older women aged ≥ 65.

Methods: Participants meeting EWGSOP2 and SDOC criteria were classified into the sarcopenia group (GS); others were placed in the non-sarcopenia group (GNS). Using an isokinetic dynamometer, we assessed peak torque (PT), maximal work (MW), and power (POW) of lower limbs.

Association between the polymorphism and the risk of hematologic malignancies: data from a meta-analysis.

The relationship between the (rs16944) polymorphism and the risk of developing hematologic malignancies remains controversial. Thus, we performed a meta-analysis to evaluate the association between polymorphism and the risk of developing hematologic malignancies. A comprehensive search was conducted to identify all eligible studies on polymorphism and hematologic malignancies.

Exercise-based physiotherapeutic interventions in frailty syndrome: A systematic review and meta-analysis.

Objective: To identify the effect of exercise interventions on physical frailty in community-dwelling older adults.

Methods: Relevant articles were searched in MEDLINE, LILACS, Scielo, Embase, and PEDro in November 2022, based on a protocol registered in PROSPERO and according to items prescribed in Report for Systematic Reviews and Meta-Analyses, using Health Sciences Descriptors (DeCS) and free terms for search strategy, with no language restrictions.

Risk of sarcopenia and mobility of older adults during the COVID-19 pandemic: the longitudinal data from the REMOBILIZE study.

Background: We assessed whether clinical, functional and behavioral factors were associated with the decrease in mobility trajectories reported in older people at risk of sarcopenia (RS) and without risk of sarcopenia (NRS) during COVID-19 pandemic.

Methods: We prospectively analyzed mobility trajectories reported in older adults with RS and NRS over 16-month follow-up (Remobilize study). The self-perceived risk of sarcopenia and mobility were assessed using the SARC-F and the Life-Space Assessment (LSA) tools, respectively.

Association Between the Length of Leukocyte Telomeres and Functional Performance of Older Adults: Observational Study.

Despite current literature pointing to a link between shortened telomeres and aging, chronic diseases, and geriatric syndromes, the precise implications of this connection remain unclear. The aim of this exploratory, cross-sectional, observational study was to investigate the association between the relative telomere length (RTL) of peripheral blood leukocyte subtypes (mononuclear cells and granulocytes) and physical performance using the Short Physical Performance Battery (SPPB) in older adults. A cohort of 95 participants was recruited, which included men and women aged over 60 years (70.

Methods: Searches were performed in six databases (Medline, Embase, ScienceDirect, Web of Science, The Cochrane Library and Lilacs) and reproducibility studies were included. Cronbach's alpha and the classification proposed by Terwee et al.

A dual-role for IL-10: From leukemogenesis to the tumor progression in acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer in the world, and accounts for 25% of all childhood cancers among children under 15 years of age. Longitudinal studies have shown that children with ALL are born with a deregulated immune response that, together with postnatal environmental exposures, favor the onset of the disease. In this context, IL-10, a key cytokine in the regulation of the immune response, presents itself as a paradoxical mediator, initially influencing the development of ALL through the regulation of inflammatory processes and later on the progression of malignancy, with the increase of this molecule in the leukemia microenvironment.

Insights Regarding the Role of Inflammasomes in Leukemia: What Do We Know?

Inflammation is a physiological mechanism of the immune response and has an important role in maintaining the hematopoietic cell niche in the bone marrow. During this process, the participation of molecules produced by innate immunity cells in response to a variety of pathogen-associated molecular patterns and damage-associated molecular patterns is observed. However, chronic inflammation is intrinsically associated with leukemogenesis, as it induces DNA damage in hematopoietic stem cells and contributes to the creation of the preleukemic clone.

Combined Training Improves Executive Functions Without Changing Brain-Derived Neurotrophic Factor Levels of Middle-Aged and Older Adults with Type 2 Diabetes.

Background: Type 2 diabetes mellitus (T2DM) provokes executive function and long-term memory decrements, and aerobic plus resistance training (combined training) may alleviate this T2DM-related cognitive impairment. Brain-derived neurotrophic factor (BDNF) levels have been found to be related to cognitive performance.

Aim: To analyze the effects of 8-week combined training on executive functions and circulating BDNF levels of subjects with T2DM and verify the association between BDNF levels and combined training-induced changes in executive functions and long-term memory.

Allostatic load and physical performance in older adults: Findings from the International Mobility in Aging Study (IMIAS).

Objective: This study aimed to evaluate the association between Allostatic Load (AL) and physical performance scores in older adults from four cities in North and South America.

Methods: In this cross-sectional study, data from 1101 volunteers from three countries (Canada, Brazil, and Colombia) from the International Mobility in Aging Study (IMIAS) were used to evaluate the association between AL index and Short Physical Performance Battery (SPPB) scores. Three multiple linear regression models adjusted by age, Socioeconomic Status (SES), chronic conditions, depression symptoms, and Leganés Cognitive Test (LCT) were developed to estimate the independent association between SPPB and AL.

Association of Social Support Network with Telomere Length: A Cross-Sectional Study with Community-Dwelling Older Adults.

Considering that telomere length can be determined not only by issues related to cell biology but also by aspects related to social factors and environmental exposures, studies on the relationship between social aspects and telomere length can help to better understand the still scarcely known aspects of the human aging process. Thus, this research seeks to verify whether social support networks are associated with telomere length in older adults. This is a cross-sectional study conducted with 448 individuals aged at least 60 years living in the urban area of an inland Brazilian municipality.

Association of Toll-like receptors polymorphisms with the risk of acute lymphoblastic leukemia in the Brazilian Amazon.

Acute lymphoblastic leukemia (ALL) is the most common hematologic malignancy in children in childhood. Single-nucleotide polymorphism (SNPs) in key molecules of the immune system, such as Toll-like receptors (TLRs) and CD14 molecules, are associated with the development of several diseases. However, their role in ALL is unknown.

Association Between Physical Functioning and Time Until a New Hospitalization in Community-Dwelling Older Adults: A Prospective Cohort Study.

Background And Purpose: Physical functioning refers to the ability to independently perform activities that require physical ability, and may be an important tool for predicting a higher risk of hospitalization. The objective of this study was to verify whether aspects of physical functioning are independently associated with the risk for new hospitalization in older adults seen in primary health care.

Methods: This prospective cohort study consisted of 473 older adults 60 years and older who had not been hospitalized in the prior year.
