RESUMO
BACKGROUND: Older adults present a variety of oral diseases and conditions, in addition to co-morbidities and limited access to dental care, which significantly impact their oral health-related quality of life (OHRQoL). There are many instruments published to measure OHRQoL. However, it is challenging for clinicians and researchers to choose the best instrument for a given purpose. PURPOSE: To identify OHRQoL instruments available for older adults and summarize the evidence on the conceptual and measurement model, psychometric properties, interpretability, and administration issues of OHRQoL instruments available for older adults through a systematic review. METHODS: A systematic search was conducted in MEDLINE, EMBASE, LILACS, and CENTRAL up to February 2023. Articles reporting information on the concept model measurement, psychometric properties, and administration issues of an instrument measuring OHRQoL in older adults were included. Two researchers independently evaluated each instrument using the Evaluating Measures of Patient-Reported Outcomes (EMPRO) tool. The overall score and seven attribute-specific scores were calculated (range 0-100): Conceptual and measurement model, Reliability, Validity, Responsiveness, Interpretability, Burden, and Alternative forms. RESULTS: We identified 14 instruments evaluated in 97 articles. The overall score varied between 73.7 and 8.9, with only six questionnaires over the threshold score 50.0. EORTC QLQ OH-15 (cancer-specific questionnaire) achieved the highest score (73.7), followed by OHIP (generic OHRQoL questionnaire) (66.9), GOHAI (generic OHRQoL questionnaire) (65.5), and OHIDL (generic OHRQoL questionnaire) (65.2). Overall, the Conceptual and measurement model and Validity showed the best performance, while Responsiveness and Interpretability showed the worst. Insufficient information was presented for an overall evaluation of DSQ and OHAI. CONCLUSION: The evidence supports using EORTC QLQ-OH15 as a specific instrument to assess OHRQoL in cancer patients and the OHIP-49, GOHAI, or OHIDL as generic instruments to assess OHRQoL either for cross-sectional or longitudinal studies in older adults.

BACKGROUND: Population ageing poses a challenge to improving the well-being of older adults, particularly in terms of oral health. Promoting self-efficacy in oral health behaviours is crucial for maintaining this population's health and quality of life. The Oral Health Self-Efficacy Scale (OHSES) has been widely used to assess dental self-efficacy and is considered comprehensive and reliable. However, there is a need to validate OHSES for Spanish-speaking older adults. This study aimed to assess the reliability and validity of the translated questionnaire for use in the older Chilean population. METHODS: A sample of 188 older adults, aged 60 years and above residing independently in the community, were recruited by accessing databases from the National Senior Citizen Service and various community organisations within the region of La Araucanía. The participants underwent comprehensive oral examinations and oral health interviews, focusing on variables such as OHSES, Oral health-related quality of life (OHIP-14Sp), assessment of remaining teeth, knowledge and attitudes toward oral health, and sociodemographic characteristics. The validity of the translated questionnaire was assessed through translation and cross-cultural adaptation, cognitive debriefing, and face and content validation. The psychometric properties of the questionnaire were evaluated through measures of internal consistency (Cronbach's alpha), content validity (Content validity index), construct validity (factor analysis and Pearson correlation analysis), and test-retest reliability (intraclass correlation). RESULTS: The Spanish version of OHSES demonstrated adequate face and content validity. The confirmatory factor analysis confirmed a two-factor scale with 7 items for a better fit. The scale demonstrated high internal consistency (Cronbach's alpha = 0.821) and acceptable test-retest reliability (ICC = 0.411). Correlations were found between the OHSES score, the number of remaining teeth, knowledge and attitudes towards oral health, and the OHIP-14Sp (p < 0.01). CONCLUSIONS: This study confirms the validity of the Spanish version of the Oral Health Self-Efficacy Scale for older adults in Chile. The scale is expected to be helpful in assessing self-efficacy in dental interventions and collecting data for international comparisons. This research opens new dimensions in patient-reported assessment of oral health.

BACKGROUND: The prevalence and consequences of traumatic dental injuries (TDI) make them a public health problem. Trustworthy TDI clinical practice guidelines (CPGs) assist clinicians in determining a diagnosis and guide them to the most appropriate therapy. The aim of this systematic survey was to identify and evaluate the quality of CPGs for the diagnosis, emergency management, and follow-up of TDIs. MATERIALS AND METHODS: A systematic search was carried out in MEDLINE, EMBASE, Epistemonikos, Trip database, CPG websites, and dental societies to identify documents providing recommendations for the emergency and sequelae management of TDIs. Reviewers assessed the included guidelines independently and in duplicate, using the AGREE II instrument. ANOVA or Student's t-tests were used to determine the attributes of CPGs associated with the total score in AGREE II. RESULTS: Ten CPGs published between 2010 and 2020 were included, mostly from Europe (n = 6). The overall agreement between reviewers was very good (0.94; 95%CI 0.91-0.97). The mean scores (the higher the score, the better the domain assessment) per domain were as follows: Scope and purpose 78.0 ± 18.9%; stakeholder involvement 46.9 ± 29.6%; rigour of development 41.8 ± 26.7%; clarity of presentation 75.8 ± 17.6%; applicability 15.3 ± 18.8%; and editorial independence 41.7 ± 41.7%. The overall mean rate was 4 ± 1.3 out of a maximum score of 7. Two guidelines were recommended by the reviewers for use in practice and rated as high quality. CPGs developed by government organizations showed a significantly higher overall score. CONCLUSIONS: The overall quality of CPGs on TDI was suboptimal. CPG developers should synthesize the evidence and formulate recommendations using high-quality methodologies and standards in a structured, transparent, and explicit way.

Addiction is a chronic and potentially deadly disease considered a global health problem. Nevertheless, there is still no ideal treatment for its management. The alterations in the reward system are the most known pathophysiological mechanisms. Dopamine is the pivotal neurotransmitter involved in neuronal drug reward mechanisms and its neuronal mechanisms have been intensely investigated in recent years. However, neuroglial interactions and their relation to drug addiction development and maintenance of drug addiction have been understudied. Many reports have found that most neuroglial cells express dopamine receptors and that dopamine activity may induce neuroimmunomodulatory effects. Furthermore, current research has also shown that pro- and anti-inflammatory molecules modulate dopaminergic neuron activity. Thus, studying the immune mechanisms of dopamine associated with drug abuse is vital in researching new pathophysiological mechanisms and new therapeutic targets for addiction management.

BACKGROUND: Gallbladder cancer (GBC) is the most common tumor of the biliary tract. The incidence of GBC shows a large geographic variability, being particularly frequent in Native American populations. In Chile, GBC represents the second cause of cancer-related death among women. We describe here the establishment of three novel cell lines derived from the ascitic fluid of a Chilean GBC patient, who presented 46% European, 36% Mapuche, 12% Aymara and 6% African ancestry. RESULTS: After immunocytochemical staining of the primary cell culture, we isolated and comprehensively characterized three independent clones (PUC-GBC1, PUC-GBC2 and PUC-GBC3) by short tandem repeat DNA profiling and RNA sequencing as well as karyotype, doubling time, chemosensitivity, in vitro migration capability and in vivo tumorigenicity assay. Primary culture cells showed high expression of CK7, CK19, CA 19-9, MUC1 and MUC16, and negative expression of mesothelial markers. The three isolated clones displayed an epithelial phenotype and an abnormal structure and number of chromosomes. RNA sequencing confirmed the increased expression of cytokeratin and mucin genes, and also of TP53 and ERBB2 with some differences among the three cells lines, and revealed a novel exonic mutation in NF1. The PUC-GBC3 clone was the most aggressive according to histopathological features and the tumorigenic capacity in NSG mice. CONCLUSIONS: The first cell lines established from a Chilean GBC patient represent a new model for studying GBC in patients of Native American descent.

BACKGROUND: The Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale was developed to measure oral health-related quality of life (OHRQoL). The aim of this study was to cross-culturally adapt the parent-reported version for toddlers of PedsQL™ Oral Health Scale into Spanish and to assess the acceptability, reliability and validity of this version in Chilean preschool population. METHODS: The PedsQL™ Oral Health Scale for toddlers was cross-culturally adapted for the Spanish language using the recommended standards. To assess metric properties, a cross-sectional study was carried out with 301 children aged 2 to 5 years in Carahue, Chile. Chilean versions of the PedsQL™ Oral Health Scale, PedsQL™ 4.0 Generic Core Scales, and Early Childhood Oral Health Impact Scale (ECOHIS) were completed by the children's parents. Dental caries, malocclusion and dental trauma were examined by trained dentists. The PedsQL™ Oral Health Scale was administrated a second time 14-21 days after. The reliability of the scale was verified by analysis of internal consistency (Cronbach's alpha) and reproducibility (Intraclass correlation coefficient - ICC). The validity of the construct was assessed by confirmatory factor analysis and known groups method. The convergent validity was assessed by calculating the Spearman's correlation with the ECOHIS questionnaire. RESULTS: The PedsQL™ Oral Health Scale demonstrated good reliability, with Cronbach's alpha coefficient of 0.79 and ICC of 0.85. A moderate-to-strong correlation was found between the PedsQL™ Oral Health Scale and the ECOHIS questionnaire (- 0.64); the PedsQL™ Oral Health Scale score was lower in children with poor than those with excellent/very good oral health (median 100 vs 85, p < 0.001); it also was lower in children with caries than in those caries-free (median 100 vs 90, p < 0.001). No statistically significant differences were found among groups according to malocclusion and traumatic dental injuries. CONCLUSIONS: The PedsQL™ Oral Health Scale for toddlers in Spanish showed to be equivalent to the original version, and its psychometric properties were satisfactory for application in a Chilean pre-school population.

BACKGROUND/AIM: Traumatic dental injuries (TDI) are a public health problem, given their prevalence and consequences. However, their epidemiology is uncertain due to a general lack of quality data capture. The aim of this study was to evaluate the validity and usability of a mobile phone-based application for community-based surveillance of traumatic dental injuries. MATERIALS AND METHODS: A mobile phone-based application, Dental Trauma Tracker (DTT), was developed. This system involves a mobile application for general users to report TDIs and a Web application for researchers to generate epidemiological data. The DTT evaluation used mixed methods and was conducted in three phases: (a) validation of a trauma identification system using preselected TDI images; (b) design evaluation by experts; and (c) usability evaluation measured by the reporting of three fictitious TDI cases and using the System Usability Scale (SUS). RESULTS: In the first phase, 182 participants participated. Most images showed over 95% accuracy, indicating that they adequately represented the type of dentoalveolar trauma being evaluated (κ = 0.75). The design evaluation identified nine usability problems-four of them with a "High priority" to be fixed, four with "Low priority," and one "No fix necessary." A total of 29 volunteers participated in the usability evaluation. The mean time for users to complete all of the reports was 7.8 ± 3.0 minutes. Mean SUS score was 67.4 ± 21.9 (Range: 0-100; worst to best). The global agreement between cases registered with the gold standard was also "Substantial" (κ = 0.71). CONCLUSIONS: This preliminary evaluation confirmed the App's usability, using a sample of potential users, as well as reporting on the results of an expert panel review of the DTT. These are the minimum requirements necessary before further expansion and widespread implementation occurs to confirm these results.

BACKGROUND: Thyroxine (T4) has been positively associated with tumor cell proliferation, while the effect of triiodothyronine (T3) on cell proliferation has not been well-established because it differs according to the type of cell line used. In Mexico, it has been reported that 14.5% of adult women have some type of thyroid dysfunction and abnormalities in thyroid function tests have been observed in a variety of non-thyroidal illnesses, including breast cancer (BC). These abnormalities might change with body mass index (BMI) because thyroid hormones are involved in the regulation of various metabolic pathways and probably by menopausal status because obesity has been negatively associated with BC in premenopausal women and has been positively associated with BC in postmenopausal women. METHODS: To assess the association between serum thyroid hormone concentration (T4 and T3) and BC and the influence of obesity as an effect modifier of this relationship in premenopausal and postmenopausal women, we measured serum thyroid hormone and thyroid antibody levels in 682 patients with incident breast cancer (cases) and 731 controls, who participated in a population-based case-control study performed from 2004 to 2007 in three states of Mexico. We tested the association of total T4 (TT4) and total T3 (TT3) stratifying by menopausal status and body mass index (BMI), and adjusted for other health and demographic risk factors using logistic regressions models. RESULTS: Higher serum total T4 (TT4) concentrations were associated with BC in both premenopausal (odds ratio (OR) per standard deviation = 5.98, 95% CI 3.01-11.90) and postmenopausal women (OR per standard deviation = 2.81, 95% CI 2.17-3.65). In premenopausal women, the effect of TT4 decreased as BMI increased while the opposite was observed in postmenopausal women. The significance of the effect modification was marginal (p = 0.059) in postmenopausal women and was not significant in premenopausal women (p = 0.22). Lower TT3 concentrations were associated with BC in both premenopausal and postmenopausal women and no effect modification was observed. CONCLUSIONS: There is a strong association between BC and serum concentrations of TT3 and TT4; this needs to be further investigated to understand why it happens and how important it is to consider these alterations in treatment.

BACKGROUND: The Early Childhood Oral Health Impact Scale (ECOHIS) measures the impact of dental diseases on Oral Health-Related Quality of Life both in children and their families. The aim of this study was to develop a Chilean Spanish version of the ECOHIS that is conceptually equivalent to the original and to assess its acceptability, reliability and validity in the preschool population of Chile. METHODS: The Chilean version of the ECOHIS was obtained through a process including forward and back-translation, expert panel, and cognitive debriefing interviews. To assess metric properties, a cross-sectional study was carried out in Carahue, Southern Chile (April-October 2016). Children younger than six years old without systemic diseases, disabilities or chronic medication from eleven public preschools were included. Parents were invited to complete the Chilean version of the ECOHIS, PedsQL™4.0 Generic Core and PedsQL Oral Health scales, and to answer global questions about their children's general and oral health. A subsample was administrated ECOHIS a second time 14-21 days after. A clinical examination was performed to assess dental caries, malocclusion, and traumatic dental injuries. Reliability was evaluated using measures of internal consistency (Cronbach's alpha) and reproducibility (Intraclass correlation coefficient - ICC). Construct validity was assessed by testing hypotheses based on available evidence about known groups and relationships between different instruments. RESULTS: The content comparison of the back-translation with the original ECOHIS showed that all items except one were conceptually and linguistically equivalent. The cognitive debriefing showed a suitable understanding of the Chilean version by the parents. In the total sample (n = 302), the ECOHIS total score median was 1 (IQR 6), floor effect was 41.6%, and ceiling effect 0%. Cronbach's alpha was 0.89 and the ICC was 0.84. The correlation between ECOHIS and PedsQL™4.0 Generic Core was weak (r = 0.21), while it was strong-moderate (r = 0.64) with the PedsQL Oral Health scale. In the known groups comparison, the ECOHIS total score was statistically higher in children with poor than excellent/very good oral health (median 11.6 vs 0, p < 0.01), and in the high severity than in the caries-free group (median 8 vs 0.5, p < 0.01). No differences were found according to malocclusion and traumatic dental injuries groups. CONCLUSIONS: These results supported the feasibility, reliability and validity of the Chilean version of ECOHIS questionnaire for preschool children through proxy.

OBJECTIVES: To evaluate the quality of clinical practice guidelines (CPGs) for dental caries prevention in children and adolescents MATERIALS AND METHODS: We performed a systematic search of CPGs on caries preventive measures between 2005 and 2016. We searched MEDLINE, EMBASE, LILACS, TripDatabase, websites of CPG developers, compilers of CPGs, scientific societies and ministries of health. We included CPGs with recommendations on sealants, fluorides and oral hygiene. Three reviewers independently assessed the included CPGs using the AGREE II instrument. We calculated the standardised scores for the six domains and made a final recommendation about each CPG. Also, we calculated the overall agreement among calibrated reviewers with the intraclass correlation coefficient (ICC). RESULTS: Twenty-two CPGs published were selected from a total of 637 references. Thirteen were in English and nine in Spanish. The overall agreement between reviewers was very good (ICC = 0.90; 95%CI 0.89-0.92). The mean score for each domain was the following: Scope and purpose 89.6 ± 12%; Stakeholder involvement 55.0 ± 15.6%; Rigour of development 64.9 ± 21.2%; Clarity of presentation 84.8 ± 14.1%; Applicability 30.6 ± 31.5% and Editorial independence 59.3 ± 25.5%. Thirteen CPGs (59.1%) were assessed as "recommended", eight (36.4%) "recommended with modifications" and one (4.5%) "not recommended". CONCLUSIONS: The overall quality of CPGs in caries prevention was moderate. The domains with greater deficiencies were Applicability, Stakeholder involvement and Editorial independence. CLINICAL RELEVANCE: Clinicians should use the best available CPGs in dental caries prevention to provide optimal oral health care to patients.

OBJECTIVE: Develop a predictive dynamic model to estimate future scenarios for the incidence rate of type 2 diabetes mellitus (T2DM). METHODS: A retrospective ecological study was conducted in 2013-2015 in the city of San Luis Potosí, Mexico. Secondary official data from the 58 municipalities making up the state of San Luis Potosí were analyzed. Linear correlation, multiple linear regression, and structural equations were carried out, and four predictive dynamic submodels were developed: T2DM, urban population, inhabited private dwellings that have television, and population aged 45-49 years. A holistic model was also developed. RESULTS: The structural model explains 27.2% of total variance in type 2 diabetes mellitus. Percentage of inhabited dwellings that have television weighs 4.46 non-standard units on diabetes; that of urban population, 2.84; and that of population aged 45-49 years, 156.69. Estimated scenarios for T2DM per 100 000 population for the years 2015, 2020, 2025, and 2030 were 1,052.4, 1,413.7, 1,850.1, and 2,351.1 respectively. CONCLUSION: The T2DM scenario shows exponential growth from 2000 to 2030. Risk factors according to the weight they represent in occurrence of the disease were: population aged 45-49 years, inhabited private dwellings that have television, and urban population.
RESUMO
PURPOSE: The aim was to determine the survival rate of dental implants installed in the posterior region of the maxilla after a graftless maxillary sinus lift via the lateral window approach and to identify the factors involved in the results. MATERIALS AND METHODS: A systematic search was done on MEDLINE, EMBASE, LILACS, Scopus, and Science Direct up to June 2016; additional studies were identified through an analysis of references. Primary studies in English, Spanish, Portuguese, and French were included; the selection and data extraction process was conducted by 2 investigators independently, and the methodological quality was evaluated by means of the Effective Public Health Practice Project's Quality Assessment Tool. RESULTS: The combined search identified 232 articles. After the selection process, 11 articles were identified, 9 of which were prospective and 2 were retrospective. In all of them, the graftless maxillary sinus lift was done with the immediate installation of the implant. All the studies included presented a low methodological quality. The mean survival rate of the implants was 97% with an average new intrasinus bone formation of 6.2 mm. CONCLUSION: This technique has a high implant survival although it is not possible to identify its correct indication and contraindication.

BACKGROUND: Obsessive-compulsive disorder (OCD) is a severe neuropsychiatric condition affecting 1-3% of the worldwide population. OCD has a strong genetic component, and the SLC1A1 gene that encodes neuronal glutamate transporter EAAT3 is a strong candidate for this disorder. To evaluate the impact of reduced EAAT3 expression in vivo, we studied male EAAT3 heterozygous and wild-type littermate mice using a battery of behavioral paradigms relevant to anxiety (open field test, elevated plus maze) and compulsivity (marble burying), as well as locomotor activity induced by amphetamine. Using high-performance liquid chromatography, we also determined tissue neurotransmitter levels in cortex, striatum and thalamus-brain areas that are relevant to OCD. RESULTS: Compared to wild-type littermates, EAAT3 heterozygous male mice have unaltered baseline anxiety-like, compulsive-like behavior and locomotor activity. Administration of acute amphetamine (5 mg/kg intraperitoneally) increased locomotion with no differences across genotypes. Tissue levels of glutamate, GABA, dopamine and serotonin did not vary between EAAT3 heterozygous and wild-type mice. CONCLUSIONS: Our results indicate that reduced EAAT3 expression does not impact neurotransmitter content in the corticostriatal circuit nor alter anxiety or compulsive-like behaviors.

PURPOSE: The aim of the present study was to determine the success rate of autotransplanted permanent teeth with an open apex and to identify the most influential prognostic factors. MATERIALS AND METHODS: A systematic search of the MEDLINE, EMBASE, LILACS, and SciELO databases was conducted for January 1990 to August 2015. The study eligibility criteria were primary studies that had evaluated patients with autotransplantation with an open apex, with or without preparation of the socket, and a minimum of 12 months of follow-up. The principal outcome was the success rate of autotransplanted teeth with an open apex. Two of us independently performed the selection process and data extraction. The Effective Public Health Practice Project's Quality Assessment Tool was used for the quality assessment of the studies. The odds ratio (OR) was calculated, with the 95% confidence interval (CI). RESULTS: A total of 21 studies were included in the present analysis. Of the 21 studies, 10 were retrospective and 11 were prospective. All the studies were of weak methodologic quality. The overall success rate was 89.68%, the survival rate was 98.21%, and the mean follow-up period was 6 years, 3 months (standard deviation 5.81 years). Among the prognostic factors analyzed, the premolars had a lower failure risk than did the molars (OR, 0.46; 95% CI, 0.25 to 0.84). The stage of development of the root and the autotransplantation receptor site showed no statistically significant differences. CONCLUSIONS: The overall success rate and survival were high, despite the methodologic limitations of the included studies. Further study is needed of the prognostic factors that influence the success of autotransplantation with an open apex.

Background: Limited attention has been given to oral health challenges faced by older Indigenous populations, especially in rural settings, where disparities exist. This study aims to assess oral health in a rural Mapuche community in southern Chile, utilizing geriatric technology support, and exploring the connection between geriatric health and oral well-being to fill a gap in this context. Methods: A cross-sectional study was conducted involving 76 independent older adults from a rural Mapuche community who required dental care. Assessments were in a remote care setting gathering extensive data including comprehensive geriatric assessments, medical and dental conditions using a geriatric teledentistry platform (TEGO®). Statistical analysis involved descriptive analysis, logistic regression, and both multiple correspondence analysis and k-means cluster analysis. Results: The sample comprised individuals with limited formal education and a high degree of vulnerability. Geriatric assessments unveiled cognitive deterioration, frailty, depression risk, and multimorbidity. A distribution of the DMFT index, number of remaining teeth, number of occluding pairs, number of teeth with restorative needs and other relevant clinical findings was conducted based on sociodemographic, and medical-geriatric-dental characteristics, and additionally, a Multinomial Logistic Regression Analysis of Dentition Variables in Relation to Geriatric Assessments was performed. The dental burden was substantial, with an average DMFT index of 25.96 (SD 4.38), high prevalence of non-functional dentition (89.3%), periodontal disease (83%), xerostomia (63.2%) and oral mucosal lesions (31.5%). Age, lower education, depression, daily medication number and sugary consumption frequency were associated with a decreased average number of teeth (p < 0.05). Multiple correspondence analysis and k-means cluster analysis identified 4 clusters, with the edentulous and functional dentition groups being the most distinct. Conclusion: This study uncovers a substantial dental burden and intricate medical-geriatric conditions interlinked among Indigenous older adults in a rural Chilean Mapuche community. The implementation of a geriatric technological ecosystem in the community enabled the resolution of less complex oral health issues and facilitated remote consultations with specialists, reducing the necessity for travel to health centers. This underscores the need for innovative dental public health initiatives to address health disparities and improve the overall well-being of older Indigenous adults.

Background: Chagas disease (CD) is transmitted by vectors but can also be transmitted orally through contaminated food, drinks, or meat. The One Health perspective aims to understand the complex interaction between human, animal, and environmental health in controlling disease. This study analyzed risk factors and drew lessons from past outbreaks of orally transmitted CD to develop effective preventive strategies. Methods: A simultaneous mixed methods study was conducted. The study consisted of two phases: an ecological epidemiological analysis at the municipal level using secondary data spanning from 1992 to 2023, and semistructured interviews with health providers and policymakers at the national level in Colombia. The results from both phases were triangulated to gain a comprehensive understanding of the topic. Results: A total of 64 outbreaks, infecting 302 individuals, were reported. Most of these outbreaks (89.2%) were classified as family-related, and they occurred most frequently during the months of April to June (46.6%). It is worth noting that a significant number of these outbreaks took place in municipalities that lacked vector control plans. Risk factors for oral transmission included the location of food preparation, poor housing quality, food preparation water source, the presence of vectors/marsupials, forest type, and climatic variables. Interviews conducted emphasized the importance of implementing outbreak plans and providing staff training to effectively address the issue. Conclusion: A One Health approach strengthening prevention, surveillance, case management and cross-sectoral collaboration is needed to control outbreaks and reduce transmission in Colombia. Preparedness plans and education of health professionals are also important. This study identified modifiable risk factors to guide public health interventions.
RESUMO
Objectives: To determine the prevalence of frailty among community-dwelling older adults in regional Victoria, Australia. Methods: Frailty status of 376 participants from the Crossroads II cross-sectional study was assessed by selected markers of frailty. The selected variables were psychometrically tested. Associations between frailty and socio-demographic, environmental and health factors were analysed using chi-square, ANOVA and binary logistic regression (BLR). Results: Estimated prevalence of frailty was 39.4%. BLR indicated that frailty decreased with higher educational attainment, (OR = .23; 95% CI: .10-.51) increased for divorced/separated participants (OR = 2.68; 95% CI: 1.29-5.56) and when having three (OR = 3.27; 95% CI: 1.07-9.98), four (OR = 7.20; 95% CI: 2.22-23.31) or five or more chronic conditions (OR = 9.18; 95% CI: 2.83-29.72). Discussion: Frailty in this Australian regional community-dwelling sample was higher than other studies conducted in urban areas of Australia. Present results highlight the importance of exploring the multidimensionality of the frailty construct to have a better understanding which factors are associated with the development of this syndrome.

Clavulanic acid (CLAV) is a non-antibiotic ß-lactam that has been used since the late 1970s as a ß-lactamase inhibitor in combination with amoxicillin, another ß-lactam with antibiotic activity. Its long-observed adverse reaction profile allows it to say that CLAV is a well-tolerated drug with mainly mild adverse reactions. Interestingly, in 2005, it was discovered that ß-lactams enhance the astrocytic expression of GLT-1, a glutamate transporter essential for maintaining synaptic glutamate homeostasis involved in several pathologies of the central nervous system (CNS). This finding, along with a favorable pharmacokinetic profile, prompted the appearance of several studies that intended to evaluate the effect of CLAV in preclinical disease models. Studies have revealed that CLAV can increase GLT-1 expression in the nucleus accumbens (NAcc), medial prefrontal cortex (PFC), and spinal cord of rodents, to affect glutamate and dopaminergic neurotransmission, and exert an anti-inflammatory effect by modulating the levels of the cytokines TNF-α and interleukin 10 (IL-10). CLAV has been tested with positive results in preclinical models of epilepsy, addiction, stroke, neuropathic and inflammatory pain, dementia, Parkinson's disease, and sexual and anxiety behavior. These properties make CLAV a potential therapeutic drug if repurposed. Therefore, this review aims to gather information on CLAV's effect on preclinical neurological disease models and to give some perspectives on its potential therapeutic use in some diseases of the CNS.

It is unclear how well self-rated oral health (SROH) reflects actual oral health status in the rural Australian population. Therefore, this study aimed to compare the clinically assessed oral health status and SROH of adults living in rural Australia. The data were from 574 participants who took part in the Crossroads II cross-sectional study. Three trained and calibrated dentists evaluated the oral health status of participants based on WHO criteria. SROH was assessed with the question 'Overall, how would you rate the health of your teeth and gums?', with a score ranging from excellent = 5 to poor = 1. A logistic regression analysis (LRA) was performed, allowing us to assess factors associated with SROH. The mean age of participants was 59.2 years (SD 16.3), and 55.3% were female. The key results from the LRA show poorer SROH in those with more missing teeth (OR = 1.05; 95% CI; 1.01-1.08), more decayed teeth (OR = 1.28; 95% CI: 1.11-1.46), and more significant clinical attachment loss of periodontal tissue (6mm or more) (OR = 2.63; 95% CI: 1.29-5.38). This study found an association between negative SROH and clinical indicators used to measure poor oral health status, suggesting that self-rated oral health is an indicator of oral health status. When planning dental healthcare programs, self-reported oral health should be considered a proxy measure for oral health status.
RESUMO
BACKGROUND: Hydromyelia is a common magnetic resonance imaging (MRI) finding associated with compressive myelopathy caused by intervertebral disc extrusion (IVDE). OBJECTIVES: To describe the MRI features of hydromyelia and explore its relationship to clinical history, neurological severity, and the duration of cord compression. ANIMALS: Ninety-one client-owned dogs with a focal compressive myelopathy secondary to thoracolumbar IVDE. METHODS: A retrospective observational study was conducted in which MRIs were blindly evaluated to grade and localize hydromyelia and measure the degree of spinal cord compression. Duration and severity of clinical signs were recorded. Differences between hydromyelia grades in these variables were statistically assessed using a Wilcoxon and Kruskal Wallis test. Receiver operator curve analysis was used to determine the sensitivity and specificity for duration of clinical signs to predict the presence of hydromyelia. RESULTS: Hydromyelia was identified at sites of IVDE in 84 of 91 dogs. An absence of hydromyelia was associated a with statistically longer duration of clinical signs (mean 73.1, IQR 76 days) when compared to cases with mild (mean 17.7, IQR 7.25 days, P = .006) or severe (mean 17.9, IQR 10.25 days, P = .006) hydromyelia. Duration of clinical signs <14 days was 78.6% sensitive and 85.7% specific for predicting the presence of hydromyelia. CONCLUSIONS AND CLINICAL IMPORTANCE: The MRI finding of hydromyelia might be a predictor of lesion chronicity in focal IVDE, helping to guide planning of hemilaminectomy surgery.
