Translation of culturally and contextually informed diabetes training for Aboriginal primary health care providers on Aboriginal client outcomes: Protocol of a cluster randomized crossover trial of effectiveness.

BACKGROUND: Indigenous populations globally have significantly high rates of type 2 diabetes compared to their non-Indigenous counterparts. This study aims to implement and evaluate the effectiveness of a culturally and contextually informed Aboriginal Diabetes Workforce Training Program on Aboriginal primary health care workforce knowledge, attitude, confidence, skill and practice relating to diabetes care. METHODS: A Cluster Randomised Crossover Control Trial with two arms (Group A and Group B) will be conducted with Aboriginal primary health care services in South Australia. These services primarily provide primary health care to Aboriginal and Torres Strait Islander people. All healthcare service sites will be randomised into groups A and B to receive the training program. The training program consists of three components: 1) Peer support network, 2) E-Learning modules and 3) onsite support. Aboriginal Health Workers of participating sites will be invited to participate in the monthly online peer support network and all chronic disease staff are eligible to participate in the E-Learning modules and onsite support. The Peer Support Network runs for the entirety of the study, 17 months. Training components 2 and 3 occur simultaneously and are 2.5 months in length, with a six-month washout period between the two randomised groups undertaking the training. All primary outcomes of the study relate to diabetes management in a primary health care settings and measure participants' knowledge, attitude, confidence, practice and skills. These will be collected at seven time points across the entire study. Secondary outcomes measure satisfaction of the peer support network using a survey, interviews to understand enablers and barriers to participation, health service systems characteristics through focus groups, and medical record review to ascertain diabetes patients' care received and their clinical outcomes up to 12 months post training intervention. DISCUSSION: The findings will explore the effectiveness of the training program on Aboriginal primary health care provider knowledge, attitude, confidence, skill and practice relating to diabetes care. The final findings will be published in 2027. TRIAL REGISTRATION: The study was prospectively registered in The Australian New Zealand Clinical Trials Registry (ANZCTR), with registration number ACTRN12623000749606 at ANZCTR - Registration. Universal Trial Number (UTN) U1111-1283-5257.

Supporting best practice in the management of chronic diseases in primary health care settings: a scoping review of training programs for Indigenous Health Workers and Practitioners.

Background To improve diabetes management in primary health care for the Aboriginal and Torres Strait Islander peoples population, training programs that are culturally and contextually relevant to the local context are required. Using a scoping review methodology, the aim of this review was to describe the characteristics of chronic disease management training programs for Aboriginal Health Workers and Practitioners, their effectiveness on knowledge and skills, and client-related outcomes, and the enablers, barriers to delivery and participation. Methods Following protocol parameters, a systematic search was conducted in relevant databases and grey literature. Two independent reviewers screened the title and abstract of each paper to determine if the study met the inclusion criteria. Results Of the 23 included studies, most were developed with stakeholders, profession facilitated and delivered by cultural facilitators. All training programs included content knowledge, two included a professional support network, four provided on-the-job support and six had follow-up support post-training. Modes of delivery ranged from didactic, storytelling and hands-on learning. Two studies reported significant improvement in participants' knowledge and confidence; one reported improvement in knowledge (12.7% increase pre-post training), and an increase in confidence in both clinical and non-clinical skills. Enablers (relevance, modes of learning, power of networking, improved knowledge, confidence and clinical practice) and barriers (adult learning capabilities, competing work-family commitments) were reported. Few studies reported on knowledge transfer into clinical practice and client-related outcomes. Conclusions Multifaceted training programs for Aboriginal health workers are well received and may improve workforce capability.

Priority setting: Development of the South Australian Aboriginal Chronic Disease Consortium RoadMap for Action.

ISSUES ADDRESSED: Aboriginal and Torres Strait Islander (Aboriginal) people in South Australia are overburdened by cardiovascular disease, diabetes and cancer. The South Australian Aboriginal Chronic Disease Consortium (Consortium) was established in June 2017 as a collaborative partnership to lead the implementation of three state-wide chronic disease plans using a strategic approach to identifying key priority areas for action. METHODS: In 2017-2018, the Consortium Coordinating Centre facilitated a priority setting process, which involved extensive consultation, including a prioritisation survey and stakeholder workshops. The Consortium's Aboriginal Community Reference Group was instrumental in leading the identification of priorities for action. RESULTS: The Consortium RoadMap for Action identified seven across-plan priorities and six condition-specific priorities. It acknowledged that: strengthening social and emotional well-being is central to improving health outcomes; prevention and early detection, acute management and ongoing management are all components of the continuum of care; and improving access to services, strengthening the workforce, and monitoring and evaluation are required across the continuum of care. CONCLUSION: Widespread implementation failure in the past across the health system and health services implementation and research translation highlights the value of the Consortium approach and its commitment to implementing the state-wide chronic disease plans in a collaborative manner. The Consortium relies on and fosters cross-sectoral alignment, with all key players including all public, private and Aboriginal Community Controlled health services, to progress its priorities and aspirations to improve health outcomes for Aboriginal people using evidence-based strategies. SO WHAT?: Rigorous and transparent priority setting processes that bring together research, clinical practice, health services operations, policy and community perspectives can foster intersectoral collaboration and partnership and support the implementation of shared priorities.

The protective effect of CALD identity in the presence of low income on missing teeth of Australian adults over time.

BACKGROUND: 'Culturally And Linguistically Diverse (CALD)' populations have diverse languages, ethnic backgrounds, societal structures and religions. CALD populations have not experienced the same oral health benefits as non-CALD groups in Australia. However, the socio-demographic profile of Australian CALD populations is changing. This study examined how household income modifies the oral health of CALD and non-CALD adults in Australia. METHODS: Data were from two National Surveys of Adult Oral Health (NSAOH) conducted in 2004-06 (NSAOH 2004-06) and 2017-18 (NSAOH 2017-18). The outcome was self-reported number of missing teeth. CALD status was identified based on English not the primary language spoken at home and country of birth not being Australia. Social disadvantage was defined by total annual household income. Effect-measure modification was used to verify differences on effect sizes per strata of CALD status and household income. The presence of modification was indicated by Relative Excess Risk due to Interactions (RERIs). RESULTS: A total of 14,123 participants took part in NSAOH 2004-06. The proportion identifying as CALD was 11.7% and 56.7% were in the low-income group, and the mean number of missing teeth was 6.9. A total of 15,731 participants took part in NSAOH 2017-18. The proportion identifying as CALD was 18.5% and 38.0% were in the low-income group, and the mean number of missing teeth was 6.2. In multivariable modelling, the mean ratio (MR) for CALD participants with low household income in 2004-06 was 2% lower than the MR among non-CALD participants with high household income, with the RERI being - 0.23. Non-CALD participants from lower income households had a higher risk of having a higher number of missing teeth than low income CALD individuals (MR = 1.66, 95%CI 1.57-1.74 vs. MR = 1.43 95%CI 1.34-1.52, respectively). In 2017-18, the MR for CALD participants with low household income was 3% lower than the MR among non-CALD participants with high household income, with the RERI being - 0.11. Low income CALD participants had a lower risk of missing teeth compared to their non-CALD counterparts (MR = 1.43, 95% CI 1.34-1.52 vs. MR = 1.57, 95% CI 1.50-1.64). CONCLUSIONS: The negative RERI values indicate that the effect-measure modification operates in a negative direction, that is, there is a protective element to being CALD among low income groups with respect to mean number of missing teeth.

Oral Health, Social and Emotional Well-Being, and Economic Costs: Protocol for the Second Australian National Child Oral Health Survey.

BACKGROUND: Given the significant investment of governments and families into the provision of child dental care services in Australia, continued population oral health surveillance through national oral health surveys is imperative. OBJECTIVE: The aims of this study are to conduct a second National Child Oral Health Survey (NCOHS-2) to (1) describe the prevalence, extent, and impact of oral diseases in contemporary Australian children; (2) evaluate changes in the prevalence and extent of oral diseases in the Australian child population and socioeconomic subgroups since the first National Child Oral Health Study (NCOHS-1) in 2012-2013; and (3) use economic modeling to evaluate the burden of child oral disease from the NCOHS-1 and NCOHS-2 and to estimate the cost-effectiveness of targeted programs for high-risk child groups. METHODS: The NCOHS-2 will closely mimic the NCOHS-1 in being a cross-sectional survey of a representative sample of Australian children aged 5-14 years. The survey will comprise oral epidemiological examinations and questionnaires to elucidate associations between dental disease in a range of outcomes, including social and emotional well-being. The information will be analyzed within the context of dental service organization and delivery at national and jurisdictional levels. Information from the NCOHS-1 and NCOHS-2 will be used to simulate oral disease and its economic burden using both health system and household costs of childhood oral health disease. RESULTS: Participant recruitment for the NCOHS-2 will commence in February 2024. The first results are expected to be submitted for publication 6 months after NCOHS-2 data collection has been completed. Thematic workshops with key partners and stakeholders will also occur at this time. CONCLUSIONS: Regular surveillance of child oral health at an Australian level facilitates timely policy and planning of each state and territory's dental public health sector. This is imperative to enable the most equitable distribution of scarce public monies, especially for socially disadvantaged children who bear the greatest dental disease burden. The last NCOHS was conducted in 2012-2014, meaning that these data need to be updated to better inform effective dental health policy and planning. The NCOHS-2 will enable more up-to-date estimates of dental disease prevalence and severity among Australian children, with cost-effective analysis being useful to determine the economic burden of poor child dental health on social and emotional well-being and other health indicators.

The Global Prevalence and Severity of Dental Caries among Racially Minoritized Children: A Systematic Review and Meta-Analysis.

Racially minoritized children often bear a greater burden of dental caries, but the overall magnitude of racial gaps in oral health and their underlying factors are unknown. A systematic review and meta-analysis were conducted to fill these knowledge gaps. We compared racially minoritized (E) children aged 5-11 years (P) with same-age privileged groups (C) to determine the magnitude and correlates of racial inequities in dental caries (O) in observational studies (S). Using the PICOS selection criteria, a targeted search was performed from inception to December 1, 2021, in nine major electronic databases and an online web search for additional grey literature. The primary outcome measures were caries severity, as assessed by mean decayed, missing, and filled teeth (dmft) among children and untreated dental caries prevalence (d > 0%). The meta-analysis used the random-effects model to calculate standardized mean differences (SMD) and 95% confidence intervals (95% CI). Subgroup analysis, tests for heterogeneity (I2, Galbraith plot), leave-one-out sensitivity analysis, cumulative analysis, and publication bias (Egger's test and funnel plots) tests were carried out. The New Castle Ottawa scale was used to assess risk of bias. This review was registered with PROSPERO, CRD42021282771. A total of 75 publications were included in the descriptive analysis. The SMD of dmft score was higher by 2.30 (95% CI: 0.45, 4.15), and the prevalence of untreated dental caries was 23% (95% CI: 16, 31) higher among racially minoritized children, compared to privileged groups. Cumulative analysis showed worsening caries outcomes for racially marginalized children over time and larger inequities in dmft among high-income countries. Our study highlights the high caries burden among minoritized children globally by estimating overall trends and comparing against factors including time, country, and world income. The large magnitude of these inequities, combined with empirical evidence on the oral health impacts of racism and other forms of oppression, reinforce that oral health equity can only be achieved with social and political changes at a global level.

Oral Health Inequities among CALD and Non-CALD Older Australians: A Decomposition Analysis.

BACKGROUND: Among Australia's older population, the burden of oral disease is disproportionality borne by culturally and linguistically diverse (CALD) communities. This study aims to examine changes in untreated decay surfaces (DS) between 2004-2006 and 2017-2018 among older CALD and non-CALD Australians. METHODS: Data were sourced Australian national oral health surveys conducted in 2004-2006 and 2017-2018. An Oaxaca-Blinder decomposition analysis was used to assess the contribution of socio-demographics and dental behaviours. RESULTS: A total of 246 CALD and 2853 non-CALD dentate participants aged 60+ years took part in 2004-2006, and 363 and 4278 in 2017-2018, respectively. There were increases in mean DS for both CALD (0.74 to 1.42) and non-CALD (0.72 to 1.50) groups between 2004-2006 and 2017-2018. The decomposition model showed that, for CALD participants in 2004-2006 with untreated DS, 40% of the contribution was from not having dental insurance; nearly three-quarters of the contribution was from last dental visit being over one year ago (72.9%) in 2017-2018. Among non-CALD participants in 2017-2018 with untreated DS, 42.5% of the contribution was from the last dental visit being over one year ago. CONCLUSIONS: Our findings suggest that social determinants, including increased access to dental insurance, could mitigate the oral health inequities observed.

An Aboriginal-led consortium approach to chronic disease action for health equity and holistic wellbeing.

ISSUE ADDRESSED: The Wellbeing Economy, which places human and ecological wellbeing at the centre of policy making, aligns with holistic Aboriginal and Torres Strait Islander conceptualisations of health and wellbeing. In order to address chronic diseases in South Australian Aboriginal and Torres Strait Islander populations, the South Australian Aboriginal Chronic Disease Consortium (Consortium) is fostering action in ways that align both with the Wellbeing Economy and with Health in All Policies (HiAP) approaches. METHODS: In June 2017, the Consortium was established as a collaborative partnership between government and non-government organisations, researchers, Aboriginal organisations and communities to lead the effective implementation of three state-wide chronic disease plans. A coordinating centre was funded to support and progress the work of the Consortium. RESULTS: During its first 5 years, the Consortium has developed a foundation for sustained system reform through partnering with stakeholders, leading projects and initiatives, advocating for key priorities, leveraging existing infrastructure and funding, supporting services, and coordinating delivery of priority actions using innovative approaches. CONCLUSIONS: Through the Consortium governance structure, Aboriginal and Torres Strait Islander community members, policy actors, service providers and researchers oversee, drive, influence and support the implementation of priority action initiatives. Sustained funding, competing priorities of partner organisations and project evaluation are constant challenges. SO WHAT?: A consortium approach provides direction and shared priorities, which foster collaboration across and between organisations, service providers and the Aboriginal community. Aligning with HiAP approaches and the Wellbeing Economy, it harnesses knowledge, networks and partnerships that support project implementation and reduce duplication.

A longitudinal assessment of chronic periodontitis in Australian adults.

AIM: The study aimed to estimate the incidence/progression and reversal of chronic periodontitis and to identify factors associated with chronic periodontitis in Australian adults over a 12-year period. MATERIALS AND METHODS: Data were obtained from the longitudinal component of the National Study of Adult Oral Health (NSAOH) in 2004-2006, and repeated data, among the same adults, in 2017-2018. NSAOH 2004-2006 was a population-based study of Australian adults aged 15+ years. The American Academy of Periodontology/European Federation of Periodontology case definitions were used, and then compared with two other case definitions. Multivariable Poisson regression models were used to estimate incidence rate ratios (IRRs) and reversal rate ratio (RRRs) of periodontitis. RESULTS: A total of 775 dentate Australian adults had dental examinations at both times. The proportion of incidence/progression and reversal among Australian adults was 56.4% and 11.0%, respectively. Tobacco smokers presented with more than three times higher incidence (IRR: 3.32, 95% CI: 1.50-7.60) and lower reversals (RRR: 0.94, 95% CI: 0.39-0.98) than those who had never smoked. Cessation of smoking was positively associated with periodontitis reversal. The total incidence/progression was 471.7/10,000 person-years, with reversal being 107.5/10,000 person-years. The average number of teeth lost due to periodontal disease was 1.9 in 2017-2018. Being male and not having periodontal treatment were significant risk markers for the incidence/progression of periodontitis. CONCLUSION: Smoking is a risk factor for periodontitis. Cessation of smoking is an effective means of reducing the incidence and progression of chronic periodontitis, to reduce the risk of tooth loss, and to improve overall periodontal health.

Teaching Health Sciences at the Universidad de Antioquia, Colombia

Introduction: Studying the identity of university teachers contributes to the understanding of their professional career, since their personal and professional development is projected in their work, as well as in their commitment to educational change or improvement on the basis of the concept they have of themselves and their profession. Objective: To recognize the meanings of being a health science professor at the Universidad of Antioquia, Colombia. Materials and methods: Qualitative study, based on symbolic interactionism, carried out between 2016 and 2019. Semi-structured interviews were administered to 73 teachers who had been working for more than five years in the health sciences programs offered by the Universidad de Antioquia. Data were analyzed inductively and compared with each other until achieving the creation of an explanatory table that would allow addressing the objective of the work. Results: The meaning of being a health sciences professor at the Universidad de Antioquia was expressed as follows: 1) being a trainer: since professors conceived themselves as academics and educators; 2) having ethical behaviors: being a critical and caring counselor-companion for students who generates bonds with social responsibility; and 3) being someone welcoming: being a role model in terms of social relationships and demonstrating fulfillment with their performance in their teaching practice. Conclusion: Participants conceive teaching as a way to contribute to the development of critical thinking in students and define their role as facilitators of the students' learning process. Furthermore, they have a common interest, namely, to guide, support and facilitate such process, so that students acquire tools that allow them to achieve an appropriate personal and professional development in the affective, social, and life project dimensions.

Sarcoma de Kaposi en orofaringe en paciente postrasplante renal y manejo con inhibidor de señal de coestimulación e inhibidor de mTOR

Introducción: el sarcoma de Kaposi en pacientes de postrasplante renal es poco frecuente y está asociado usualmente a infección por herpes 8 y a dosis altas de inmunosupresión. Objetivo: descripción reporte de caso de Sarcoma de Kaposi en orofaringe en paciente postrasplante renal manejo con inhibidor de señal de coestimulación e inhibidor mTOR. Presentación del caso: en este artículo se describe el caso de una paciente, con antecedente de trasplante renal, con diagnóstico de sarcoma de Kaposi en una localización muy poco frecuente: a nivel orofaríngeo. Se realiza una revisión de los factores de riesgo, patogenia y un acercamiento en el manejo. De igual manera, se realiza un seguimiento y manejo con inhibidor de señal de coestimulación (belatacept) e inhibidor de mTOR. Discusión y conclusión: el sarcoma de Kaposi es una de las neoplasias postrasplante con mayor incidencia comparativamente con la población no trasplantada, donde el papel de la reactivación de la infección viral, más el papel de la inmunosupresión, son puntos fundamentales en la génesis de la neoplasia. La determinación del estatus serológico IgG para HHV8 podría ser una estrategia de determinación del riesgo en el pretrasplante.

Introduction: Kaposi sarcoma in post-renal transplantation patients is a rare entity, usually associated with herpes 8 infection and high doses of immunosupresion. Purpose: Case report description of Kaposi's sarcoma in the oropharynx in a post-renal transplant patient managed with co-stimulation signal inhibitor and mTOR inhibitor. Case presentation: This article describes the case of a patient, with a history of renal transplant, with a diagnosis of Kaposi's sarcoma in a very rare location: oropharyngeal level. A review of the risk factors, pathogenesis and a management approach is made. Likewise, a follow-up and management with co-stimulation signal inhibitor (belatacept) and mTOR inhibitor is performed. Discussion and conclusion: Kaposi's sarcoma is one of the post-transplant neoplasms with the highest incidence compared to the non-transplanted population, where the role of viral infection reactivation, plus the role of immunosuppression, are fundamental points in the genesis of the neoplasm. The determination of IgG serological status for HHV8 could be a strategy to determine risk in pretransplantation.

Development and validation of a composed canine simulator for advanced veterinary laparoscopic training.

The development of innovative simulation models for veterinary laparoscopic surgery training is a priority today. This study aimed to describe a didactic simulation tool for the training of total laparoscopic gastropexy (TLG) with intracorporeal sutures in dogs. CALMA Veterinary Lap-trainer composite simulator (CLVTS) was developed from a plaster cast of 2 Great Dane canines mimicking the space and the correct position to carry out a TLG. After video instruction, 16 veterinarians with different degrees of experience in minimally invasive surgery (Experts, n = 6 and intermediates, n = 10) evaluated four sequential simulating TLG with intracorporeal suturing in the CLVTS. Subsequently, they completed an anonymous questionnaire analyzing the realism, usefulness, and educational quality of the simulator. The CLVTS showed a good preliminary acceptance (4.7/5) in terms of the usefulness and adequacy of the exercises that, in the participants' opinion, are appropriate and are related to the difficulty of the TLG. In addition, both experienced and intermediate surgeons gave high marks (4.5/5) to the feeling of realism, design, and practicality. There were no significant differences between the responses of the two groups. The results suggest that the CVLTS has both face and content validity. Where it can be practiced in a structured environment for the development of a total laparoscopic gastropexy with intracorporeal suture and without compromising patient safety, but still has some limitations of the scope of the study. Further studies are needed to establish the ability to assess or measure technical skills, including the degree of transferability to the actual surgical environment.

A Longitudinal Study of Chronic Periodontitis in Two Cohorts of Community-Dwelling Elderly Australians.

Background: The study aimed to estimate and compare the incidence and progression of chronic periodontitis among two generations of older Australian adults. Methods: Data were from two population-based cohort studies of Australian older adults aged 60+ years South Australian Dental Longitudinal Studies (SADLS), SADLS I (1991-1992) and SADLS II (2013-2014). American Academy of Periodontology/the U.S. Centres for Disease Control and Prevention (CDC/AAP), and the 2018 European Federation of Periodontology classification (EFP/AAP) case definitions were used to define and calculate the incidence and progression of chronic periodontitis. Multivariable Poisson regression models were used to estimate incidence risk ratios (IRRs) of periodontitis. Results: A total 567 and 201 dentate respondents had periodontal exams in SADLS I and II, respectively. The incidence rate was greater in SADLS II than in SADLS I, approximately 200 vs. 100/1000 person years, respectively. Current smokers had more than two times higher IRRs, 2.38 (1.30-4.34) and 2.30 (1.24-4.26), than their non-smoking counterparts in the previous generation under the CDC/AAP and EFP/AAP, respectively. Conclusions: The most recent generation of older adults has greater incidence and progression of periodontitis than the previous generation. Being a current tobacco smoker was a significant risk factor for both the incidence and progression of periodontitis.

Contribución del uso de XPERT MTB/RIF y su costo-efectividad en el diagnóstico de tuberculosis pulmonar y la resistencia a rifampicina: una comparación con métodos diagnósticos no moleculares / Contribution of the use of xpert MTB/RIF and its cost-effectiveness in the diagnosis of pulmonary tuberculosis and resistance to rifampicin: a comparison with non molecular diagnostic methods

Resumen Introducción: La tuberculosis es un problema de salud pública; su control requiere diagnóstico temprano y tratamiento oportuno. Xpert MTB/RIF® es una tecno logía diagnóstica basada en PCR en tiempo real, detecta el Complejo Mycobacterium tuberculosis y la susceptibilidad a rifampicina. Objetivo: Determinar la contribución del Xpert MTB/RIF y su costo-efectividad en la detección de tuberculosis y la resistencia a rifampicina en muestras respirato rias al compararlo con métodos de diagnóstico no moleculares Materiales y Métodos: Se analizaron 1.574 muestras de pacientes con sospecha de tuberculosis pulmonar que fueron procesadas para microscopía con coloración fluorescente de auramina-rodamina, Xpert MTB/RIF y cultivo en BACTEC MGIT 960. Los resultados obtenidos se compararon entre los métodos no moleculares y los moleculares para la detección de M. tuberculosis y susceptibilidad a rifampicina y se realizó un análisis comparativo de costos y costo efectividad. Resultados: 19,2% de las muestras fueron positivas por alguna de las técnicas usadas. Xpert MTB/RIF detectó M. tuberculosis en 90,4% del total de muestras positivas con un índice Kappa de 0,77 (IC95%: 0,74-0,82) comparado con el cultivo. La resistencia a rifampicina por Xpert fue 8,1%, sensibilidad 94,1% (IC95%: 73,0-99,0%), especificidad 98,4% (IC95%: 95,5-99,5%) y Kappa de 0,88 (IC95%: 0,76-1,00). La razón incremental de costo efectividad (RICE) fue menor en Xpert MTB/RIF comparada con el cultivo. Conclusión: Xpert MTB/RIF es una prueba eficiente y costo efectiva en la detección de casos de M. tuberculosis en muestras pulmonares comparado con los mé todos de diagnóstico basados en cultivo, sin embargo y a diferencia del Xpert MTB/RIF, estos pueden aportar en el diagnóstico con el aislamiento de especies de micobacterias no tuberculosas y la susceptibilidad a isoniazida y otros medicamentos.

Abstract Introduction: Tuberculosis is a public health problem its control requires early diagnosis and timely treatment. Xpert MTB/RIF is a real-time PCR based diagnostic technology, detects the Mycobacterium tuberculosis complex and rifampicin resistance. Objective: To determine the contribution of Xpert MTB/RIF and its cost-effectiveness in the detection of potential positive cases for tuberculosis and resistance to rifampicin in respiratory samples comparatively with diagnostic non molecular methods Materials and Methods: From 2013 to 2015, 1.574 clinical samples of patients with suspected pulmonary tuberculosis were evaluated by smear microscopy using auramina-rodamina stain, Xpert and culture in liquid medium BACTEC MGIT 960®. Results: 19,2% of the samples were positive for any of the methods used, Xpert detected M. tuberculosis in 90,4% of the positive samples and the concordance between Xpert and cultures had a Kappa index of 0,71 (IC95%: 0,62-0,72). Xpert identified resistance to rifampicin in 8,1% of the clinical samples studied with a sensitivity 94.1% (IC95%: 73,0-99,0%), specificity 98,4% (IC95%: 95,5-99,5%) and Kappa index 0,88 (IC95%: 0,76-1,00). Xpert had an incremental cost effectiveness ratio lower than culture (RICE). Conclusion: Xpert MTB/Rif is efficient diagnostic technique and comparable with culture in cost effectiveness for pulmonary tuberculosis diagnosis. However, culture based methods, in contrast to Xpert, may allow the isolation and identification of non tuberculosis mycobacterial species and the possibility to perform susceptibility for other antituberculous drugs.

It was found in the speed test (30 meters), a median between 5.7 and 6.7 seconds. In power (horizontal jump), a median between 1.1 and 1.6 meters (without differences with international references). In the abdominal test, a median between 16 and 21 repetitions. The physical tests by zones did not show important differences in: 30 meters stopped; 30 meters thrown; 50 meters released; jump and sit-ups. In the 600-meter test, the best result was found in "South of Urabá" with a median of 2.3 minutes (IR: 1.6 - 3.2). In the launch of the ball, the best result was found in the "Eje Bananero" with a median of 18.8 meters (IR: 14.5 - 24.5). Conclusion: a standardized battery to evaluate the nutritional status and physical condition of boys and girls (5-15 years old) allows a scientific approach for characterization, comparison with international standards and orientation of actions.

Effect of oral health literacy on self-reported tooth loss: A multiple mediation analysis.

BACKGROUND: This study aims to investigate the mediating pathways of oral health literacy (OHL) and oral health-related behaviours on the relationship between education and self-reported tooth loss among Australian adults. METHODS: Data used for studying the effects of mediating pathways are from the National Dental Telephone Interview Survey 2013, a random sample survey of Australian adults aged 18+ years. To study the mediating effects, we use counterfactual-based analysis. To decompose the effect of multiple mediator's alternate, to natural effect, methods such as interventional effects have been proposed. In this paper, we use these approaches to decompose the effect between education, OHL and oral health-related behaviours on self-reported tooth loss. Sensitivity analysis was performed for unmeasured confounding with multiple mediators. RESULTS: Data were available for 2936 Australian adults. The prevalence of persons with ≥12 self-reported tooth loss was approximately 15%. The average total causal effect from the low education group was nearly 150%, and the interventional indirect effect through OHL and the dependence of oral health-related behaviours on OHL to more than 12 missing teeth were 20% and 120%, respectively, higher than in the high education group. Sensitivity analysis indicated if the difference in the prevalence of unmeasured confounder is as big as 6% the direct effect and the indirect effect remains as observed. CONCLUSIONS: An additional two-fifths reduction on having more than 12 missing teeth for Australian adults with lower education level could be achieved if the proportion of lower OHL was decreased and optimal dental behaviours were increased.

Use of oral health care services in the United States: unequal, inequitable-a cross-sectional study.

BACKGROUND: Social determinants drive disparities in dental visiting. Disparities can be measured simply by comparing outcomes between groups (inequality) but can also consider concepts of social justice or fairness (inequity). This study aimed to assess differences in dental visiting in the United States in terms of both social inequality and inequity. METHODS: Data were obtained from a cross-sectional study-the National Health and Nutrition Examination Survey (NHANES) 2015-2016, and participants were US adults aged 30+ years. The outcome of interest, use of oral health care services, was measured in terms of dental visiting in the past 12 months. Disparity was operationalized through education and income. Other characteristics included age, gender, race/ethnicity, main language, country of birth, citizenship and oral health status. To characterize existing inequality in dental service use, we examined bivariate relationships using indices of inequality: the absolute and relative concentration index (ACI and RCI), the slope index of inequality (SII) and relative index of inequality (RII) and through concentration curves (CC). Indirect standardization with a non-linear model was used to measure inequity. RESULTS: A total of 4745 US adults were included. Bivariate analysis showed a gradient by both education and income in dental visiting, with a higher proportion (> 60%) of those with lower educational attainment /lower income having not visited a dentist. The concentration curves showed pro-higher education and income inequality. All measures of absolute and relative indices were negative, indicating that from lower to higher socioeconomic position (education and income), the prevalence of no dental visiting decreased: ACI and RCI estimates were approximately 8% and 20%, while SII and RII estimates were 50% and 30%. After need-standardization, the group with the highest educational level had nearly 2.5 times- and the highest income had near three times less probability of not having a dental visit in the past 12 months than those with the lowest education and income, respectively. CONCLUSION: The findings indicate that use of oral health care is threatened by existing social inequalities and inequities, disproportionately burdening disadvantaged populations. Efforts to reduce both oral health inequalities and inequities must start with action in the social, economic and policy spheres.

Adverse treatment outcomes in multidrug resistant tuberculosis go beyond the microbe-drug interaction: Results of a multiple correspondence analysis. / Los resultados adversos en el tratamiento de la tuberculosis resistente a múltiples fármacos sobrepasan la relación fármaco-microorganismo: resultados de un análisis de correspondencia múltiple

INTRODUCTION: Multidrug-resistant tuberculosis treatment is effective in 50% of patients due to several factors including antibiotic susceptibility of the microorganism, adverse treatment reactions, social factors, and associated comorbidities. OBJECTIVES: In this study, we describe the demographics, clinical characteristics, and factors associated with treatment outcomes in multidrug-resistant tuberculosis (MDR-TB) patients in Medellín, Colombia. MATERIALS AND METHODS: We conducted a retrospective analysis using data from patients diagnosed with MDR-TB attending Hospital La María in Medellín, Colombia, for treatment between 2010 and 2015. Patients were categorized as having successful (cured) or poor (failure, lost to follow-up, and death) treatment outcomes. Associations between demographic, clinical factors, laboratory results, treatment outcomes, and follow-up information were evaluated by univariate, multivariate, and multiple correspondence analyses. RESULTS: Of the 128 patients with MDR-TB, 77 (60%) had successful outcomes. Of those with poor outcomes, 26 were lost to follow-up, 15 died, and 10 were treatment failures. Irregular treatment, the presence of comorbidities, and positive cultures after more than two months of treatment were associated with poor outcomes compared to successful ones (p<0.05 for all). The multiple correspondence analyses grouped patients who were lost to follow-up, had HIV, and drug addiction, as well as patients with treatment failure, irregular treatment, and chronic obstructive pulmonary disease. CONCLUSION: The recognition of factors affecting treatment is essential and was associated with treatment outcomes in this series of patients. Early identification of these factors should increase the rates of treatment success and contribute to MDR-TB control.

Introducción. El tratamiento de la tuberculosis multirresistente tiene una efectividad del 50 %, afectado por múltiples factores como la sensibilidad del microorganismo, las reacciones secundarias, los factores sociales y las comorbilidades existentes. Objetivos. Describir la demografía, las características clínicas y los factores pronósticos asociados con los resultados del tratamiento en pacientes multirresistentes (TB-MDR) de Medellín, Colombia. Métodos. Se hizo un análisis retrospectivo de los datos de los pacientes con TB-MDR atendidos en el Hospital La María de Medellín, Colombia, que fueron tratados entre el 2010 y el 2015. Los pacientes se categorizaron con tratamiento exitoso (curados) o con tratamiento fallido (falla en el tratamiento, pérdida durante el seguimiento y muerte). Se determinó la asociación entre las características demográficas y clínicas, los resultados de los exámenes de laboratorio, los desenlaces del tratamiento y la información del seguimiento, utilizando análisis univariado, multivariado y de correspondencia múltiple. Resultados. De 128 pacientes con TB-MDR, 77 (60 %) tuvieron un tratamiento exitoso. De los que tuvieron un tratamiento fallido, 26 pacientes se perdieron en el seguimiento, 15 murieron y 10 tuvieron falla en el tratamiento. El tratamiento irregular, las comorbilidades y los cultivos positivos más allá de 2 meses de tratamiento se asociaron significativamente con los tratamientos fallidos (p<0,05). El análisis de correspondencia múltiple agrupó los pacientes con pérdida en el seguimiento, con HIV y tratamientos irregulares, y los pacientes con tratamientos irregulares y enfermedad pulmonar obstructiva crónica con falla en el tratamiento y muerte. Conclusión. El reconocimiento temprano de los factores que afectan el desenlace del tratamiento de los pacientes con TB-MDR es esencial; la identificación de dichos factores debería incrementar el éxito del tratamiento y contribuir al adecuado control de la TB-MDR.
