sordida, which confirms that this species has low genetic variability, with all specimens in Brazil grouped in T. sordida sensu stricto. In addition to the genetic and evolutionary importance for the knowledge of the biology of these vectors, these results are important from an epidemiological point of view, thus being able to direct vector control programs.Rabies, caused by rabies virus (RABV), is still one of the deadliest infectious diseases. Host metabolomic changes against RABV infection has not yet been fully understood. We performed untargeted metabolomics to discover the metabolites associated with RABV infection. find more The brain tissues from 20 RABV infected mice and 10 mock infected mice were used for this method. A total of 1352 differential metabolites were identified after the first-run screen, and the number reduced to 75 after second-run screen. Multivariate analysis using PLS-DA and OPLS-DA clearly discriminated the RABV infected samples from controls. Pathways enrichment analysis revealed that most differential metabolites were associated with metabolism of nucleotide and amino acid, and aminoacyl - tRNA biosynthesis and purine metabolism were the most active pathways. The findings presented in our study would promote the understanding of metabolomics changes in brains of mice after RABV infection as well as a new perspective to study the relationship between RABV and host.Methicillin-resistant Staphylococcus aureus (MRSA) is a prominent pathogen causing invasive infections such as bacteraemia. The continued excessive use of antibiotics to treat MRSA infections has resulted in the evolution of antimicrobial resistant of S. aureus. This study aims to perform a comparative evaluation of changing trends in molecular epidemiology of MRSA and clinical characteristics of patients. This study shows that ST22-MRSA-IV has gradually replaced ST239-MRSA-III as the predominant MRSA clone in the tertiary teaching hospital studied. Independent predictors of mortality among patients included devices in situ at the time of infection, pre-exposure to macrolides, catheter-related bloodstream infection and mono-microbial infection. Hence, our study affirmed community-associated MRSA, which was previously identified from individuals without any exposure to healthcare settings, has now emerged in healthcare settings, causing healthcare-associated MRSA infections.

To examine the relationship between multimorbidity and functional limitation, and how social relationships alter that association.

This cross-sectional study used data collected by self-reported questionnaires from adults aged 65 years and older living in a rural area in Japan in 2017. This analysis included complete data from 570 residents. Multimorbidity status was defined as having two chronic diseases exist simultaneously in one individual, and the function status was measured by their long-term care needs. Social relationships were assessed by the Index of Social Interaction and divided into high and low levels. Multiple logistic regression analysis was used to examine the association between social relationships and functional limitation and to assess the role of social relationships in this association.

The logistic regression model indicated that the risk of functional limitation was higher in multimorbidity participants than free-of-multimorbidity participants (OR = 2.55, 95% CI = 1.56-4.16). Compared with participants with no multimorbidity and a high level of social relationships, low level of social relationships increased the risk of functional limitation among participants both with and without multimorbidity, with the OR = 7.71, 95% CI = 3.03-19.69 and OR = 3.28, 95% CI = 1.30-8.27, respectively. However, no significant result was found in participants with multimorbidity and a high level of social relationships (P = 0.365).

Multimorbidity was associated with functional limitations. However, this association could be increased by a low level of social relationships and decreased by a high level of social relationships.

Given that increasing aging is associated with a natural decline in cognitive function, identifying effective interventions that can help to prevent cognitive decline in older adults is a research priority.

To synthesize the best evidence to assess the effectiveness of game-based brain training in improving cognitive function and to evaluate the preferred design features of the intervention.

Twelve databases, trial registries, and gray literature resources were systematically searched for in randomized controlled trials. Meta-analysis and random-effects meta-regression were conducted using Comprehensive Meta-analysis Software 3.0. Overall effect was measured using Hedges's g and determined using Z-statistics. Cochran's Q test and I

were used to investigate heterogeneity. The Grading of Recommendation, Assessment, Development, and Evaluation system was used to assess overall quality of evidence.

Fifteen trials among 759 older adults were conducted. Meta-analysis revealed that game-based brain training significantly improved processing speed (g = 0.23), selective attention (g = 0.40), and short-term memory (g = 0.35) versus a control group. Our subgroup analyses emphasized that non-time pressure games, multiplayer, computer platform, provider support, sessions ≤ 3 times per week for ≤ 60 min. each comprised a preferable design. Meta-regression identified game design (β = 0.211, p = 0.008) that had statistically significant effects on processing speed. Egger's regression asymmetry test (p = 0.293) suggested no publication bias.

Game-based brain training can be considered a supplementary intervention for improving cognitive functions in community-dwelling older adults. Future trials should use well-designed trials with large sample sizes.

The combination of a growing population of older adults and increasing prevalence and awareness of dementia diagnoses suggests that dementia worry may also intensify. As a relatively new area of investigation, the dementia worry literature is growing, but variability in definitions and measurement continue. A scoping review was conducted to gather and examine existing research, as well as assist in guiding future studies in this area. The review focused on characterizing the conceptualization, measurement, and correlates of dementia worry.

Using PubMed, CINAHL, AgeLine, and PsycINFO, a search of literature concerning dementia worry was completed.

A total of 45 articles examining dementia worry fulfilled the inclusion criteria. Most studies were cross-sectional (n = 39), quantitative (n = 38), and conducted in the United States (n = 22). Inconsistencies in the conceptualization, measurement, and correlates examined make it difficult to determine the meaning and true levels of dementia worry.

Recent attention to dementia worry has increased awareness of the basic concept and its correlates. However, the lack of unity in the definition and measurement of dementia worry impedes advancement in this research area, as well as in establishing its clinical significance.

High-quality cardiopulmonary resuscitation (CPR) saves lives after a cardiorespiratory arrest. Currently used feedback devices (FD) provide accurate information on CPR quality during training. However, there is no consensus in previous studies that have compared FD to the feedback provided by an instructor and most show methodological limitations. This study aimed to analyse the degree of agreement between an FD and an instructor in the assessment of high-quality CPR.

60 undergraduate nursing students participated in a descriptive observational study. Variables related to the quality of chest compressions (CC) and ventilation were recorded. Students were evaluated during 2-minute compression/ventilation cycles by an expert instructor and using the CPR training torso, Little Anne™ QCPR (Laerdal Medical) with its associated QCPR Instructor App software for iOS.

The degree of agreement between instructor and FD assessments was moderate-good CC rate per minute (Intracass correlation coeficiente [ICC]=0.791), complete chest recoil (ICC=0.437); CC depth (k=0.804); CC with correct depth (ICC=0.557); correct ventilations (k=0.510); ventilations per cycle (ICC=0.635); CC per cycle (ICC=0.215); overall quality of CPR (ICC=0.602). However, the degree of agreement should be considered poor since the limits were broad.

Although there were discrepancies between the FD and the instructor, it would be advisable to follow a combined approach in CPR training, whereby the quantitative feedback supplied by the FD is complemented by the qualitative assessment of an instructor.

TTO was analyzed by gas chromatography-mass spectrometry, and nanocapsules were characterized regarding mean particle size (Z-average), polydispersity index (PdI), zeta potential (ZP), pH, entrapment efficiency (EE), morphology by Atomic Force Microscopy (AFM), and anti-Cutibacterium acnes activity. The main constituents of TTO were terpinen-4-ol (37.11 %), γ-terpinene (16.32 %), α-terpinene (8.19 %), ρ-cimene (6.56 %), and α-terpineol (6.07 %). NC-TTO-Ch presented Z-average of 268.0 ± 3.8 nm and monodisperse size distribution (PdI less then 0.3). After coating the nanocapsules with chitosan, we observed an inversion in ZP to a positive value (+31.0 ± 1.8 mV). This finding may indicate the presence of chitosan on the nanocapsules' surface, which was corroborated by the AFM images. In addition, NC-TTO-Ch showed a slightly acidic pH (∼5.0), compatible with topical application. The EE, based on Terpinen-4-ol concentration, was approximately 95 %. This data suggests the nanocapsules' ability to reduce the TTO volatilization. Furthermore, NC-TTO-Ch showed significant anti-C. acnes activity, with a 4× reduction in the minimum inhibitory concentration, compared to TTO and a decrease in C. acnes cell viability, with an increase in the percentage of dead cells (17 %) compared to growth control (6.6 %) and TTO (9.7 %). Therefore, chitosan-poly(ε-caprolactone) core-shell nanocapsules are a promising tool for TTO delivery, aiming at the activity against C. acnes for the topical acne treatment.
