RESUMO
The aim of this study was to investigate the independent and joint associations of low cardiorespiratory fitness and lower-limb muscle strength with cardiometabolic risk in older adults. A total of 360 community-dwelling older adults aged 60-80 years participated in this cross-sectional study. Cardiometabolic risk was based on the diagnosis of Metabolic Syndrome and poor Ideal Cardiovascular Health according to the American Heart Association guidelines. Cardiorespiratory fitness and lower-limb muscle strength were estimated using the six-minute walk and the 30-second chair stand tests, respectively. Participants in the 20th percentile were defined as having low cardiorespiratory fitness and lower-limb muscle strength. Poisson's regression was used to determine the prevalence ratio (PR) and 95% confidence intervals (CI) of Metabolic Syndrome and poor Ideal Cardiovascular Health. Participants with low cardiorespiratory fitness alone and combined with low lower-limb muscle strength were similarly associated with a higher risk for Metabolic Syndrome (PR 1.27, 95% CI 1.09-1.48, and PR 1.32, 95% CI 1.10-1.58, respectively), and poor Ideal Cardiovascular Health (PR 1.76, 95% CI 1.25-2.47, and PR 1.65, 95% CI 1.19-2.28, respectively). Low lower-limb muscle strength alone was not associated with a higher risk for either Metabolic Syndrome or poor Ideal Cardiovascular Health (PR 1.23, 95% CI 0.81-1.87, and PR 1.11, 95% CI 0.89-1.37, respectively). Low cardiorespiratory fitness alone or combined with low lower-limb muscle strength, but not low lower-limb muscle strength alone, was associated with a higher cardiometabolic risk in older adults. The assessment of physical fitness may be a "window of opportunity" to identify youngest-old adults with a high cardiovascular disease risk.

OBJECTIVE: Analyzing the survival of older people hospitalized due to COVID-19 in Brazil and identifying its main predictive factors for death. METHOD: This is a retrospective, multicenter cohort study, based on 20,831 records of hospitalizations of older people due to SARS-CoV-2 in Brazil. The observation period was from February 28 to May 18, 2020. RESULTS: There was a reduced overall survival time of 47.70% (95% confidence interval [CI] = [46.72%, 48.67%]) in 10 days. The variables age, race, education, intensive care unit (ICU), region, day of hospitalization, time elapsed between the first symptom and hospitalization, and the municipality that provided assistance showed increased risk of death using the multiple Cox proportional-hazards model. CONCLUSION: These results emphasize the relevance of inequality and access to health services as determinants for the death of older people with COVID-19.

Vitamin D may play a significant role in regulating the rate of aging. The objective of the study was to assess vitamin D status and its associated factors in institutionalized elderly individuals. A total of 153 elderly individuals living in Nursing Homes (NH) were recruited into the study. Serum 25-hydroxyvitamin D [25(OH)D] concentration was used as the biomarker of vitamin D status, and it was considered as the dependent variable in the model. The independent variables were the type of NH, age-adjusted time of institutionalization, age, sex, skin color, body mass index, waist and calf circumference, physical activity practice, mobility, dietary intake of vitamin D and calcium, vitamin D supplementation, use of antiepileptics, and season of the year. Serum 25(OH)D concentrations less than or equal to 29 ng/mL were classified as insufficient vitamin D status. The prevalences of inadequate dietary intake of vitamin D and calcium were 95.4% and 79.7%, respectively. The prevalence of hypovitaminosis D was 71.2%, and the mean serum concentration of 25(OH)D was 23.9 ng/mL (95% confidence interval [CI]: 22.8-26.1). Serum 25(OH)D concentration was associated with the season of summer (p = 0.046). There were no associations with other independent variables (all p > 0.05). The present results showed that a high prevalence of hypovitaminosis D was significantly associated with summer in institutionalized elderly individuals.

BACKGROUND: Oropharyngeal dysphagia is a swallowing disorder with signs and symptoms which may be present in older adults, but they are rarely noticed as a health concern by older people. The earliest possible identification of this clinical condition is needed by self-reported population-based screening questionnaire, which are valid and reliable for preventing risks to nutritional status, increased morbidity and mortality. OBJECTIVE: The aim of this systematic review was to identify self-reported screening questionnaires for oropharyngeal dysphagia in older adults to evaluate their methodological quality for population-based studies. METHODS: An extensive search of electronic databases (PubMed (MEDLINE), Ovid MEDLINE(R), Scopus, Cochrane Library, CINAHL, Web of Science (WOS), PsycINFO (APA), Lilacs and Scielo) was conducted in the period from April to May 2017 using previously established search strategies by the two evaluators. The methodological quality and the psychometric properties of the included studies were evaluated by the COSMIN (Consensus based Standards for the selection of health Measurement Instruments) checklist and the quality criteria of Terwee and colleagues, respectively. RESULTS: The analysed information was extracted from three articles which had conducted studies on the prevalence of oropharyngeal dysphagia by self-reported screening questionnaires, showing poor methodological quality and flaws in the methodological description to demonstrate its psychometric properties. CONCLUSION: This study did not find any self-reported screening questionnaires for oropharyngeal dysphagia with suitable methodological quality and appropriate evidence in its psychometric properties for elders. Therefore, the self-reported questionnaires within the diagnostic proposal require greater details in its process for obtaining valid and reliable evidence.
RESUMO
This study used a next-generation sequencing approach to identify the bacterial taxa occurring in the advanced front of caries biofilms associated with pulp exposure and irreversible pulpitis. Samples were taken from the deepest layer of dentinal caries lesions associated with pulp exposure in 10 teeth diagnosed with symptomatic irreversible pulpitis. DNA was extracted and the microbiome was characterized on the basis of the V4 hypervariable region of the 16S rRNA gene by using paired-end sequencing on Illumina MiSeq device. Bacterial taxa were mapped to 14 phyla and 101 genera composed by 706 different OTUs. Three phyla accounted for approximately 98% of the sequences: Firmicutes, Actinobacteria and Proteobacteria. These phyla were also the ones with most representatives at the species level. Firmicutes was the most abundant phylum in 9/10 samples. As for genera, Lactobacillus accounted for 42.3% of the sequences, followed by Olsenella (13.7%), Pseudoramibacter (10.7%) and Streptococcus (5.5%). Half of the samples were heavily dominated by Lactobacillus, while in the other half lactobacilli were in very low abundance and the most dominant genera were Pseudoramibacter, Olsenella, Streptococcus, and Stenotrophomonas. High bacterial diversity occurred in deep dentinal caries lesions associated with symptomatic irreversible pulpitis. The microbiome could be classified according to the relative abundance of Lactobacillus. Except for Lactobacillus species, most of the highly prevalent and abundant bacterial taxa identified in this study have been commonly detected in infected root canals. The detected taxa can be regarded as candidate pathogens for irreversible pulpitis and possibly the pioneers in pulp invasion to initiate endodontic infection.

AIMS: To determine the prevalence of urinary incontinence (UI) and associated factors in the institutionalized elderly. METHODS: A cross-sectional study is presented herein, conducted between October and December 2013, in 10 nursing homes in the city of Natal (Northeast Brazil). Individuals over the age of 60, who reside in institutions, were included. Hospitalized individuals and those at end of life were excluded. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity, and Pfeiffer test for cognitive status). UI was verified through the Minimum Data Set (MDS) version 3.0, which was also used to assess urinary devices and UI toileting programs. The Chi-square test (or Fisher's exact test), the linear Chi-square test, and logistic regression were utilized to model associations. RESULTS: The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 58.88% (CI 95%: 53.42-64.13) and the final model revealed a statistically significant association between UI and white race, physical inactivity, stroke, mobility impairment, and cognitive decline. The most frequent UI type was functional UI and toileting programs (prompted voiding) were only applied to approximately 8% of residents. CONCLUSIONS: It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke, and other geriatric syndromes such as immobility and cognitive disability.

INTRODUCTION: Bacterial taxa in the forefront of caries biofilms are candidate pathogens for irreversible pulpitis and are possibly the first ones to invade the pulp and initiate endodontic infection. This study examined the microbiota of the most advanced layers of dentinal caries in teeth with irreversible pulpitis. METHODS: DNA extracted from samples taken from deep dentinal caries associated with pulp exposures was analyzed for the presence and relative levels of 33 oral bacterial taxa by using reverse-capture checkerboard hybridization assay. Quantification of total bacteria, streptococci, and lactobacilli was also performed by using real-time quantitative polymerase chain reaction. Associations between the target bacterial taxa and clinical signs/symptoms were also evaluated. RESULTS: The most frequently detected taxa in the checkerboard assay were Atopobium genomospecies C1 (53%), Pseudoramibacter alactolyticus (37%), Streptococcus species (33%), Streptococcus mutans (33%), Parvimonas micra (13%), Fusobacterium nucleatum (13%), and Veillonella species (13%). Streptococcus species, Dialister invisus, and P. micra were significantly associated with throbbing pain, S. mutans with pain to percussion, and Lactobacillus with continuous pain (P < .05). Quantitative polymerase chain reaction revealed a mean total bacterial load of 1 × 10(8) (range, 2.05 × 10(5) to 4.5 × 10(8)) cell equivalents per milligram (wet weight) of dentin. Streptococci and lactobacilli were very prevalent but comprised only 0.09% and 2% of the whole bacterial population, respectively. CONCLUSIONS: Several bacterial taxa were found in advanced caries lesions in teeth with exposed pulps, and some of them were significantly associated with symptoms. A role for these taxa in the etiology of irreversible pulpitis is suspected.

The objective of this work is to determine the prevalence of FI and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December 2013, in 10 nursing homes (NHs) of the city of Natal (Northeast Brazil). Individuals over the age of 60 were included in the study, while those hospitalized or in terminal phase were excluded. Data collection included sociodemographic information, FI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). FI was verified through the Minimum Data Set (MDS) 3.0, which was also used to assess toileting programs. The Chi-square test and the linear Chi-square test were performed for bivariate analysis, as well as logistic regression for multivariate analysis. The final sample consisted of 321 elderly, mostly females, with mean age of 81.5 years. The prevalence of FI was 42.68% (CI 95%, 37.39-48.15). Most residents presenting FI were always incontinent (83.9%) and the most frequent incontinence type was total FI (solid and liquid stools). Incontinence control measures were applied only to 9.7% of the residents. The final model revealed a statistically significant association between FI and functional and cognitive impairments. It is concluded that FI is a health issue that affects almost half of the institutionalized elderly, and is associated with functional and cognitive disability.

This randomized trial evaluated the 12-month clinical performance of nanofill, a nanohybrid, and a microhybrid composite in restorations in occlusal cavities of posterior teeth. This study utilized 41 patients, each of whom had three molars affected by primary caries or the need to replace restorations. All restorations were performed in accordance with the manufacturer's recommendations and evaluated in accordance with U.S. Public Health Service-modified criteria. Based on the results of the present study, the material investigated demonstrated acceptable clinical performance after 12 months of clinical service. Long-term re-evaluations are necessary for a more detailed analysis of these composites.

INTRODUCTION: This cross-sectional study evaluated the prevalence of apical periodontitis (AP) and endodontic treatment in type 2 diabetic individuals as compared with nondiabetics from an adult Brazilian population. METHODS: Full-mouth radiographs from 30 type 2 diabetic and 60 age- and sex-matched nondiabetic individuals were examined, and the presence of AP lesions in untreated and root canal-treated teeth was recorded. The number of teeth and the prevalence of root canal treatment were also evaluated. RESULTS: AP was significantly more present in teeth from diabetic individuals (98/652, 15%) than in nondiabetic controls (162/1,368, 12%) (P = .05). A separate analysis of untreated and treated teeth revealed that significance was mostly because of the prevalence of AP in untreated teeth, which was 10% in diabetics and 7% in nondiabetics (P = .03). No significant difference between diabetics and nondiabetics was observed for the other parameters under study, including the prevalence of AP in root canal-treated teeth, the number of teeth in the oral cavity, the number of treated teeth per individual, the number of individuals with at least 1 AP lesion or 1 root canal treatment, and the number of teeth with AP per individual (P > .05). CONCLUSIONS: AP was significantly more prevalent in untreated teeth from type 2 diabetics. This suggests that diabetes may serve as a disease modifier of AP in the sense that individuals with diabetes can be more prone to develop primary disease. However, findings do not confirm that diabetes may influence the response to root canal treatment because treated teeth had no increased prevalence of AP when compared with controls.
