d multimorbidity. We recommend a low threshold for performing the 5-CST in clinical settings and provide a protocol for its use.

Poor performance in the 5-CST is increasingly common with age and is associated with a cluster of other factors that characterize risk for poor ageing such as physical inactivity, impaired cognition, and multimorbidity. We recommend a low threshold for performing the 5-CST in clinical settings and provide a protocol for its use.In recent years, nonhuman ancient DNA studies have begun to focus on larger sample sizes and whole genomes, offering the potential to reveal exciting and hitherto unknown answers to ongoing biological and archaeological questions. However, one major limitation to such studies is the substantial financial and time investments still required during sample screening, due to uncertainty regarding successful sample selection. This study investigates the effect of a wide range of sample properties including latitude, sample age, skeletal element, collagen preservation, and context on endogenous content and DNA damage profiles for 317 ancient and historic pinniped samples collected from across the North Atlantic and surrounding regions. Using generalised linear and mixed-effect models, we found that a range of factors affected DNA preservation within each of the species under consideration. The most important findings were that endogenous content varied significantly within species according to context, the type of skeletal element, the collagen content and collection year. There also appears to be an effect of the sample's geographic origin, with samples from the Arctic generally showing higher endogenous content and lower damage rates. Both latitude and sample age were found to have significant relationships with damage levels, but only for walrus samples. βNicotinamide Sex, ontogenetic age and extraction material preparation were not found to have any significant relationship with DNA preservation. Overall, skeletal element and sample context were found to be the most influential factors and should therefore be considered when selecting samples for large-scale ancient genome studies.

This study aimed to determine how increased muscle mass and athletic performance in adolescence contribute to the prevention of sarcopenia in old age, accounting for the type of sport and the continuation of exercise habits. We compared the prevalence of sarcopenia, its components (low appendicular skeletal muscle mass, low muscle strength, and low physical function), and musculoskeletal pain using data from two cohorts former athletes who competed in the 1964 Tokyo Olympics and general community-dwelling older adults living in Kashiwa City, Chiba Prefecture.

We analysed the data from 101 former Olympic athletes (mean age±SD 75.0±4.4years; 26% female) and 1529 general community-dwelling older adults (74.1±5.5years; 49% women). We assessed sarcopenia (defined by the Asian Working Group for Sarcopenia revised in 2019) and musculoskeletal pain and considered potential confounding factors such as demographic characteristics, for example, sex and exercise habits.

The prevalence of sarcopenia was significantl in sports with physical contact. Our results warrant further promotion of exercise in adolescence and beyond as well as providing safety education, which is required to prevent the development of sarcopenia and musculoskeletal pain in old age.

We observed a lower prevalence of sarcopenia and superior appendicular skeletal muscle mass and strength in the former Olympic athletes, especially among those that continued their exercise habits and those in sports with high exercise intensity. Conversely, low physical function and higher musculoskeletal pain scores were more prevalent in former Olympic athletes, especially among athletes who competed in sports with physical contact. Our results warrant further promotion of exercise in adolescence and beyond as well as providing safety education, which is required to prevent the development of sarcopenia and musculoskeletal pain in old age.

Type 2 diabetes (T2D) is a global health problem that will be diagnosed in almost 300 million people by 2025 according to the World Health Organization. Before being diagnosed with T2D, individuals may have glucose levels above normal but below the diabetic range. This condition is known as prediabetes. Studies showed that people with prediabetes had an increase in several pro-inflammatory cytokines in their serum and in their fasting glucose levels. The answer remains unclear when inflammation begins in the pancreas and islets, and what is the extent of this inflammation.

Subjects with haemoglobin A1c levels from 5.7% to 6.4% were classified as pre-diabetic. Sections of pancreas and isolated islets from normal donors and donors with prediabetes were tested for markers of inflammation and glucose-stimulated insulin secretion (GSIS).

Gene and protein expression of the inflammatory markers resistin, interleukin-1 beta, tumour necrosis factor-alpha, interleukin-6, and monocyte chemoattractant protein-1 increased in donors with prediabetes compared to normal donors. GSIS response was significantly decreased in pre-diabetic islets compared to normal islets. Donors with prediabetes also had decreased expression of CD163+ cells but not CD68+ cells.

Based on our findings, inflammation and islet dysfunction may be more significant than originally thought in people with prediabetes. Rather than being in a normal state before diabetes occurs, it appears that subjects are already in an early diabetic condition resembling more closely T2D.

Burnout refers to a constellation of feelings of exhaustion, depersonalization, and low sense of personal accomplishment that develops secondary to long-term occupational stress. Several studies have identified that health care professionals are a high-risk occupational group for burnout, but knowledge about this syndrome among midwives has not been fully explored. The purpose of this study was to perform a systematic review of the prevalence and levels of burnout among midwives and analyze the related factors.

The following databases were searched CINAHL, LILACS, MEDLINE, ProQuest, PsycINFO, SciELO, and Scopus. Any date of publication was acceptable. Literature from different countries was included. Studies were appraised for quality following the recommendations of the Oxford Centre for Evidence-Based Medicine.

The literature review identified 27 studies with a total of N = 5612 midwives. The main factors related to burnout were working conditions such as work overload, lack of autonomy, and professiotors related to burnout syndrome. Intervention programs for midwives should be aimed at reducing emotional exhaustion and enhancing personal accomplishment.

Peri-implant bone level values have been used as the clinical standard of reference to describe the status of a dental implant, despite the fact that their significance for the long-term survival of the implant has never been properly assessed.

To challenge the assumption that the natural course of peri-implant bone loss is the loss of the implant.

This article is a narrative review on reasons and interpretations of marginal bone level changes around dental implants.

Different views regarding the pattern and progression of marginal bone loss depending on dental specialties have been identified. However, the present finding of a negative correlation between an increasing cumulative marginal bone loss and a decreasing risk of implant failures over time indicates that peri-implant marginal bone loss does not necessarily represent a condition of disease. Reduction of marginal bone levels may be observed in a majority of patients during follow-up time, with only a minority of those patients losing implantsimplant marginal bone loss does not necessarily represent a condition of disease. Reduction of marginal bone levels may be observed in a majority of patients during follow-up time, with only a minority of those patients losing implants and implant-supported prostheses in the long term. Bone level changes seem often to occur as a consequence of physiological processes and/or as an adaptation to altered external as well as host response factors. Periodical radiological assessments of implant-restorations remain a valid diagnostic tool for the detection of potential implant fractures, loss of osseointegration, screws working loose and for the detection of the few cases with advanced, continuously progressing marginal bone loss during time. The detection of peri-implant marginal bone loss at one time point should not be immediately considered as a sign of ongoing pathology and of an increased risk of future loss of the implant in question.Mounting evidence shows that MicroRNAs (miRNAs) and their target genes are aberrantly expressed in many cancers and are linked to tumor occurrence and progression, especially in esophageal cancer (EC). This study purposed to explore new biomarkers related to the prognosis of EC and to uncover their potential mechanisms in promoting tumor progression. We identified 162 differentially expressed miRNAs and 4555 differentially expressed mRNAs in EC. Then, a risk model involving three miRNAs (miR-4521, miR-3682-3p, and miR-1269a) was designed to predict prognosis in EC patients. Furthermore, 7 target genes (Rho GTPase-activating protein 24, Chromobox 3, Contactin-associated protein 2, ELOVL fatty acid elongase 5, LIF receptor subunit alpha, transmembrane protein 44, and transmembrane protein 67) were selected for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses to reveal their potential mechanisms in promoting EC progression. After a series of correlation analyses, miRNA target genes were found to be significantly positively or negatively associated with immune infiltration, tumor microenvironment, cancer stemness properties, and tumor mutation burden at different degrees in EC. To further elucidate the role of miRNA signature in cancer progression, we performed a pan-cancer analysis to determine whether these genes exert similar effects on other tumors. Interestingly, the miRNA target genes altered expression on tumor immunity; however, pan-cancer progression was the same as that of EC. Thus, we explored the immune landscape of the miRNA signature and its target genes in EC and pan-cancer. These findings demonstrated the versatility and effectiveness of our model in various cancers and provided a new direction for cancer management.The present study aimed to determine the chemical composition and biological activity of the essential oil obtained from Phyllogonium viride Brid. (Phyllogoniaceae, Bryophyta), whose samples were collected in southern Brazil. For the first time, the cytotoxic activity of the essential oil of P. viride in breast and colorectal tumor cells (MCF-7 and HCT-116) was evaluated, as well as the cytotoxic potential of this oil in non-tumoral cells of human immortalized keratinocytes (HaCaT) via MTT assay. The compounds majorly found in P. viride essential oil were β-bazzanene (20.30 %), β-caryophyllene (17.06 %), β-chamigrene (14.02), and germacrene B (11.72 %). Treatment with P. viride essential oil in the different tested cell lines did not induce any toxicity in most of the tested concentrations. These data contribute to generating new scientific information about this understudied plant species. Furthermore, the chemical characterization of the compounds present in the essential oil of P. viride can lead to greater elucidation of its biotechnological potential.
