Correlation between low handgrip strength and metabolic syndrome in older adults: a systematic review.

Muscle weakness has been associated to insulin resistance and metabolic syndrome in the general population. However, it is still unclear whether this association is maintained in older adults. This study investigated correlations between low handgrip strength (HGS) and metabolic syndrome, or some of its components, in older adults through a systematic review of the literature. Searches were conducted in the Virtual Health Library Regional Portal, Scopus, Cochrane, Embase, MEDLINE/ PubMed, SciELO, and Web of Science databases for relevant studiesinvestigating muscle weakness (measured by hand dynamometer) and metabolic syndrome or its components in older adult populations, published up to September 2023. From the 2050 references initially identified, 20 studies, comprising a total of 31,264 older adults of both genders, completely met the inclusion/exclusion criteria. Eighteen studies showed that lower HGS was associated with metabolic syndrome or some of its risk factors, such as abdominal obesity, hyperglycemia, insulin resistance, dyslipidemia, or high blood pressure. Two studies found that older men with high blood pressure had increased HGS. Most studies included in this systematic review revealed a significant correlation between reduced HGS and metabolic syndrome or some of its components, especially abdominal obesity and insulin resistance. We conclude that below-average HGS can be associated with metabolic syndrome in older adults.

Correlation between low handgrip strength and metabolic syndrome in older adults: a systematic review

ABSTRACT Muscle weakness has been associated to insulin resistance and metabolic syndrome in the general population. However, it is still unclear whether this association is maintained in older adults. This study investigated correlations between low handgrip strength (HGS) and metabolic syndrome, or some of its components, in older adults through a systematic review of the literature. Searches were conducted in the Virtual Health Library Regional Portal, Scopus, Cochrane, Embase, MEDLINE/PubMed, SciELO, and Web of Science databases for relevant studies investigating muscle weakness (measured by hand dynamometer) and metabolic syndrome or its components in older adult populations, published up to September 2023. From the 2050 references initially identified, 20 studies, comprising a total of 31,264 older adults of both genders, completely met the inclusion/exclusion criteria. Eighteen studies showed that lower HGS was associated with metabolic syndrome or some of its risk factors, such as abdominal obesity, hyperglycemia, insulin resistance, dyslipidemia, or high blood pressure. Two studies found that older men with high blood pressure had increased HGS. Most studies included in this systematic review revealed a significant correlation between reduced HGS and metabolic syndrome or some of its components, especially abdominal obesity and insulin resistance. We conclude that below-average HGS can be associated with metabolic syndrome in older adults.

The use of sentinel-2 imagery to generate vegetations maps for the Northern Antarctic peninsula and offshore islands.

We used Sentinel-2 imagery time series to generate a vegetation map for the Northern part of the Antarctica Peninsula and offshore islands, including the South Shetlands. The vegetation cover was identified in the NDVI maximum value composite image. The NDVI values were associated with the occurrence of algae (0.15 - 0.20), lichens (0.20 - 0.50), and mosses (0.50 - 0.80). The vegetation cover distribution map was validated using the literature information. Generating a vegetation map distribution on an annual basis was not possible due to high cloud cover in the Antarctic region, especially in coastal áreas, so optical images from 2016 to 2021 were necessary to map the vegetation distribution in the entire study área. The final map analyzed in association with the weather data shows the occurrence of a microenvironment over the western islands of the Antarctic Peninsula that provided vegetation growth conditions. The Sentinel-2 images with 10m spatial resolution allow the assembly of accurate vegetation distribution maps for the Antarctica Peninsula and Islands, the Google Earth Engine cloud computing being essential to process a large amount of the satellite images necessary for processing these maps.

Abstract Objective To identify the publications that discussed COVID-19 as an occupational injury and its notification by health workers. Methods The search for this scoping review explored national and international literature, between 2020 and 2021, in English, Portuguese and Spanish, in the databases of the Regional Portal of the Virtual Health Library, in MEDLINE through PubMed and in Capes Journal Portal used: Embase, Scopus, Web of Science, CINAHL. The texts were imported into EndNote, duplicates were removed and exported to the Rayyan application, and the articles were included in an Excel spreadsheet with the labels: COVID-19 as injuries at work and Notification of COVID-19. Results A total of 5665 studies were identified, excluding 2088 duplicates, resulting in 3577 publications, selected by title and abstract. Of these, 3280 did not meet the inclusion criteria, resulting in 297 articles. Of these, 10 were selected for full text analysis because they dealt with COVID-19 as an injury at work and/or notification of this condition by health workers. Two articles were excluded because they were a literature review, remaining 8 as the study's corpus. Conclusion Although certain countries already recognize COVID-19 as an occupational injury, some workers still have difficulties in relating the SARS-CoV-2 infection with work in health care, characterizing it as an occupational injured. Everyone should be guided and trained regarding the recognition of COVID-19 as an occupational injury and notify its occurrence, since the definition of the infection as a notifiable disease already exists.

Complementary roles of wild boar and red deer to animal tuberculosis maintenance in multi-host communities.

The contribution of wildlife species to pathogen maintenance in multi-host communities has seldom been quantified. To assess the relative contribution of the main wildlife hosts of animal tuberculosis (TB) to its maintenance, we estimated the basic reproduction number (R0) of Mycobacterium tuberculosis complex in wild boar and red deer at 29 sites in the Iberian Peninsula. Host abundance and true TB prevalence were estimated for each species at each site by sampling from distributions incorporating the uncertainty in the proportion of the population harvested each year, sensitivity, and specificity of the diagnostic methods, while excretion of mycobacteria was estimated using site-occupancy models. The distributions of these parameters were then used to estimate, at each site, the R0,wild boar (range 0.1 - 55.9, average 8.7, standard deviation 11.8), and the R0,red deer (0.1 - 18.9, 2.2, 3.9). Animal TB is maintained in epidemiological scenarios ranging from any single species acting as a maintenance host (the wild boar in 18 sites and the red deer in 5), to facultative multi-host disease (6 sites). The prevalence of TB in the red deer is likely an important driver of the epidemiology in multi-host communities. The wild boar was the main maintenance host of TB in most of the study sites and could have an epidemiological role linking the wildlife multi-host community and livestock.

Effects of vitamin D supplementation on glycemic control of children and adolescents with type 1 diabetes mellitus: a systematic review.

OBJECTIVES: To evaluate the effect of vitamin D supplementation on glycemic control in children and adolescents with T1DM. CONTENT: A systematic search was conducted of the Medline/PubMed, Web of Science, Embase, BVS/Lilacs, Cochrane Library, Scopus, Cinahl, Food Science, and FSTA databases. Two reviewers independently extracted article data and assessed quality. SUMMARY: A total of 1,613 eligible articles were retrieved, ten of which met the selection criteria: eight clinical trials, one retrospective cohort study, and one cross-sectional study. Regarding the cutoff points used to classify vitamin D status, most of the studies set deficiency at 25-hydroxyvitamin D <20 ng/mL, sufficiency at ≥30 ng/mL, and insufficiency as the interval between these values. Regarding intervention strategies, most used cholecalciferol for supplementation, but there was great variation in the dose and supplementation time. When evaluating the effect of vitamin D supplementation on HbA1c, a significant improvement in glycemic control was observed in 50% of the studies. However, only one of these studies was classified as being of positive methodological quality, with three having their quality classified as neutral and one as negative. OUTLOOK: There is yet no consistent evidence on the effect of vitamin D supplementation on glycemic control as an adjuvant in the treatment of children and adolescents with T1DM.

Antarctic biological soil crusts surface reflectance patterns from landsat and sentinel-2 images.

The remote sensing techniques must be used to obtain long-term information in remote areas, like the Antarctic continent, to monitor the environmental productivity and its changes. The aim of this work was to analyze the surface reflectance profile patterns for the Antarctic biological soil crusts (algae, lichens, and mosses) in an area of Nelson Island (South Shetland Islands, maritime Antarctic), calculated from Landsat and Sentinel-2 images to identify its similarities and differences due to targets, sensors and acquired date. The surface reflectance values for Antarctic biological soil crusts are similar for those observed for biological soil crusts in other Earth extreme environments, like deserts. In Landsat images, the differences among biological soil crusts surface reflectance were identified at visible and near-infrared wavelengths and for Sentinel-2 images, the differences occur at visible, red-edge and shortwave infrared wavelengths, showing the feasibility of using surface reflectance products to identify these different crusts, despite its inherent pixel spectral mixture. Long-term biophysical parameters from such crusts as retrieved from orbital data is not possible due to very low cloud-free images over the Antarctic, which prevents building a consistent surface reflectance time-series which covers all biological soil crusts growth season.

CO2 Laser and radiofrequency compared to a sham control group in treatment of stress urinary incontinence (LARF study arm 3). A randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: Female stress urinary incontinence (SUI) is a prevalent condition, and conservative treatment options are needed. Were evaluated CO2 laser and radiofrequency as treatment for SUI. METHODS: One hundred thirty-nine women with SUI were eligible and randomized in a three-arm double-blind randomized controlled trial into radiofrequency (RF), laser (LS) and sham control (SCT) groups, with 3-monthly outpatient treatment sessions. One hundred fourteen women were included, 38 in each group, during a 12-month follow-up. The primary outcomes were: subjective improvement of SUI, evaluated on a Likert scale, and objective cure, which was a composite outcome defined according to negative stress tests, voiding diary and pad test. Questionnaires were also applied. The sample size was calculated to provide 80% power to identify a 20% difference between groups, p < 0.05. RESULTS: Subjective improvement and objective cure of SUI were identified respectively in 72.6% and 45.2% in LS and in 61.7% and 44.7% in RF, both significantly higher than the 30.0% and 14.0% in SCT. Considering only mild cases (pad test < 10 g), objective cure was achieved in 66.7% in LS, 63.6% in RF and 22.2% in SCT. Significant reduction in the number of episodes of urinary incontinence was found according to voiding diaries (p = 0.029) and pad weight (p = 0.021). A significant reduction in urgency and urinary loss during sexual intercourse was observed only with LS and RF. Improvement in quality of life was also verified by the I-QoL and ICIQ-SF in favor of the energy-treated groups. CONCLUSIONS: CO2 laser and radiofrequency are outpatient options for SUI treatment, with no major complications. They had similar results and presented better results than in the sham control group.

Machine perfusion versus cold storage in renal preservation of deceased donors with brain death: systematic review and meta-analysis. / Máquina de perfusão versus armazenamento estático na preservação renal de doadores com morte encefálica: revisão sistemática e metanálise.

With the increasing use of machine perfusion in kidney transplantation, it has been observed that dynamic ischemia correlates with the improvement of organ preservation. In this context, we performed a systematic review that aimed to evaluate the efficacy of the portable machine perfusion (LifePort Kidney Transporter Machine®), used in Brazil, compared to cold storage, regarding the delayed graft function of deceased donors with brain death. Literature search was carried out in LILACS, MEDLINE via PubMed, Scopus, Clarivate Analytics, Cochrane Library, Embase, and SciELO, as well as in Google Scholar manually. The systematic review consisted only of randomized clinical trials. For meta-analysis, relative risk and odds ratio were evaluated. Eighty-six documents were identified and two papers from European and Brazilian groups were selected at the end, with eligibility criteria for meta-analysis. In these, 374 kidneys were assigned to machine perfusion and 374 kidneys were assigned to cold storage. Delayed graft function was observed in 84 and 110 patients, respectively. In meta-analysis, a risk ratio of 0.7568 (p=0.0151) and an odds ratio of 0.6665 (p=0.0225) were obtained, both with a 95% confidence interval. Machine perfusion reduced the incidence of delayed graft function of deceased donors with brain death.

Foi efetuada pesquisa bibliográfica, nas bases LILACS, MEDLINE via PubMed, Scopus, Clarivate Analytics, Cochrane Library, Embase, SciELO, além de busca manual no Google acadêmico. A revisão sistemática, finalizada em abril 2017, foi constituída somente por ensaios clínicos randomizados. Para metanálise, foram avaliadas Razão de Risco e Razão de Chance. Foram identificados 86 documentos e selecionados, ao final, dois artigos com critérios de elegibilidade para metanálise, de grupos europeus e brasileiros. Nestes, 374 rins foram alocados para a máquina de perfusão, e igual número para o armazenamento estático. A função retardada do enxerto foi constatada em 84 e 110 pacientes, respectivamente. Na metanálise, foram obtidas uma Razão de Risco de 0,7568 (p=0,0151) e uma Razão de Chance de 0,6665 (p=0,0225), ambas com intervalo de confiança de 95%. A máquina de perfusão reduziu a incidência de função retardada do enxerto de doadores com morte encefálica.

ABSTRACT: At the end of the 20th and early 21st century, agricultural systems incorporated definitively a new mission: to generate goods for a world population that continues to grow and whose way of life demand food with low environmental impact. Soybean is the main raw material for the production of biodiesel in Brazil, accountably responsible for 82.4% of the total produced between 2006 and 2013. The Brazilian state of Rio Grande do Sul (RS), which is formed by the Pampa and the Atlantic forest biomes, was responsible for 35.7% of the country's biodiesel production in the referred period. The aim of this paper was to verify the impact of the increased area of soybean cultivation in land use in Rio Grande do Sul State, in the period between 1990 and 2015, considering separately its two biomes (Pampa and Atlantic Forest) original areas, using both census dataset and satellite images. We used the period from 1990 to 2000 as before commodity rising price (BCRP) and the period from 2000 to 2013 as commodity rising price (CRP). The 505,162 ha from Atlantic Forest biome and 1,192,115ha from Pampa biome were added to soybean production in the CRP period. In the Atlantic Forest, this enlargement occurred in the border of the main production area, while in Pampa biome conversion of natural grassland to crop land was the main reason for the large increment in the cultivated area.

RESUMO: No final do século XX e início do século XXI, os sistemas agrícolas incorporaram definitivamente uma nova missão: gerar energia para uma população mundial que continua a crescer e que demanda por seu modo de vida, não só alimentos, mas também, cada vez mais energia, principalmente, energia com baixo impacto ambiental. A soja permaneceu a principal matéria-prima para a produção de biodiesel no Brasil, no período de 2006 a 2013, em que foi responsável por 82,4%, sendo o estado do RS responsável por 35,7% do total da produção brasileira de biodiesel. O objetivo deste trabalho é verificar o impacto do aumento da área de cultivo de soja no uso da terra no Rio Grande do Sul, no período entre 1990 e 2015. Considera-se, separadamente, as áreas originais de seus dois biomas (Pampa e Mata Atlântica), usando o conjunto de dados do IBGE e imagens de satélite. Utilizou-se o período de 1990 a 2000 como o período anterior ao da suba de preços de commodities (BCRP) e, o período de 2000 a 2013 como período de aumento do preço das commodities (CRP). Um total de 505.162ha do bioma Mata Atlântica e de 1.192.115ha do bioma Pampa foram incorporados à produção de soja no período CRP. No bioma Mata Atlântica, o aumento ocorreu nos limites da área cultivada, enquanto que no bioma Pampa através da conversão da área com pastagem nativa.

Multiscale Trend Analysis for Pampa Grasslands Using Ground Data and Vegetation Sensor Imagery.

This study aimed to evaluate changes in the aboveground net primary productivity (ANPP) of grasslands in the Pampa biome by using experimental plots and changes in the spectral responses of similar vegetation communities obtained by remote sensing and to compare both datasets with meteorological variations to validate the transition scales of the datasets. Two different geographic scales were considered in this study. At the local scale, an analysis of the climate and its direct influences on grassland ANPP was performed using data from a long-term experiment. At the regional scale, the influences of climate on the grassland reflectance patterns were determined using vegetation sensor imagery data. Overall, the monthly variations of vegetation canopy growth analysed using environmental changes (air temperature, total rainfall and total evapotranspiration) were similar. The results from the ANPP data and the NDVI data showed the that variations in grassland growth were similar and independent of the analysis scale, which indicated that local data and the relationships of local data with climate can be considered at the regional scale in the Pampa biome by using remote sensing.

Validation, reliability, and responsiveness of Prolapse Quality of Life Questionnaire (P-QOL) in a Brazilian population.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to translate and validate a Brazilian version of the "Prolapse Quality of Life Questionnaire" (P-QOL) an instrument to assess quality of life of women with genital prolapse. METHODS: Sixty-five patients answered the P-QOL twice. The reliability was assessed using Cronbach's alpha coefficient and validity was assessed comparing symptom scores between affected and asymptomatic women and comparing symptom scores with prolapse stages. Responsiveness was obtained with patients who underwent to genital prolapse surgical corrections. RESULTS: The results have showed that the Brazilian Portuguese version of P-QOL has had very good psychometric properties. All items achieved a Cronbach's alpha greater than 0.70. The test-retest reliability confirmed that the questionnaire was able to detect changes in quality-of-life after treatment. CONCLUSIONS: We concluded that the Portuguese version of the P-QOL is a very good instrument to assess quality-of-life in women with genital Prolapse.

Caracterização espectral multitemporal dos cereais de estação fria em imagens de satélite com média resolução espacial / Multitemporal spectral characterization of cool season cereals in satellite images with moderate spatial resolution

A fim de avaliar os padrões de resposta de áreas cultivadas com cereais de estação fria destinados para pastagens e para produção de grãos em imagens de satélite, foram analisados perfis temporais de índice de vegetação por diferença normalizada (NDVI), adquiridos em 29 áreas cultivadas com trigo e azevém anual, nos Estados do Rio Grande do Sul e Paraná. Para cada área foi informada a espécie cultivada (trigo ou azevém anual) e a coordenada do ponto central da área adquirido por meio do Global Positioning System (GPS). Foram usadas as imagens do sensor MODIS (Moderate Resolution Imaging Spectroradiometer), com resolução espacial de 250 metros, sobre cada área monitorada, de onde os valores de NDVI foram extraídos. Os perfis temporais de NDVI mostraram que os cultivos de produção de grãos têm um comportamento espectral típico de cultivos agrícolas, enquanto que, nas áreas cultivadas para a produção de pastagem, não foi observado esse mesmo padrão. As diferenças nos padrões temporais observadas se devem a modificações que o pastoreio impõe na fenologia e na morfologia dessas plantas.

In order to evaluate the satellite image patterns between such cool season cereals cultivated areas intended for grazing or grain production, Normalized Difference Vegetation Index (NDVI) temporal profiles were analyzed. This data was acquired from twenty nine wheat and annual ryegrass cultivated areas in the states of Rio Grande do Sul and Paraná. For each area, the cultivated species (wheat or ryegrass), as well as the respective central point coordinates, acquired via Global Positioning System (GPS) was informed. NDVI values were extracted over each monitored area from MODIS (Moderate Resolution Imaging Spectroradiometer) sensor images, with spatial resolution of 250 meters. The NDVI temporal profiles showed that grain production areas have a typical agricultural field spectral pattern. The same pattern was not observed for the grazing pasture areas. The differences observed in these temporal patterns are defined by the changes that grazing has imposed on the phenology and morphology of these plants.
