Triple Jeopardy in Oral Health: Additive Effects of Immigrant Status, Education, and Neighborhood.

PURPOSE: To estimate the additive effects of parent's nativity status/language spoken at country of birth, education, and area-level socioeconomic status (SES) on untreated dental caries among children aged 5 to 9 y in Australia. METHODS: Cross-sectional population-based data were obtained from the 2014 National Child Oral Health Study (N = 12,140). Indicators of social position used to explore additive effects on dental caries included nativity status, language, university degree, and neighborhood socioeconomic level. Multiple-way interactions were examined, and departure from additivity resulting from 2- and 3-way interactions were estimated as relative excess risk due to interaction (RERI). RESULTS: Children marginalized across multiple layers of disadvantage had substantially higher frequencies of dental caries compared with children in the most advantaged category. RERI for the 3-way interaction between immigrant status, education, and neighborhood SES was negative (RERI3: -0.14; 95% confidence interval [CI]: -1.68, 1.40). When operationalizing language, education, and neighborhood SES, the joint effect of the 3 marginalized positions was additive (RERI3: 0.43; 95% CI: -2.08, 2.95). CONCLUSION: Children marginalized across multiple intersecting axes of disadvantage bear the greatest burden of dental caries, with frequencies surpassing the cumulative effect of each social position alone. Findings emphasize the need to account for intersecting inequities and their oral health effects among children with immigrant backgrounds. KNOWLEDGE TRANSFER STATEMENT: Our analysis underscores the necessity for policies and public health strategies targeting dental caries-related inequities to comprehensively account for various indicators of social disadvantage, particularly encompassing language proficiency, educational attainment, and neighborhood socioeconomic status. Within the intricate interplay of these factors, we identify a vulnerable subgroup comprising children with the highest prevalence of dental decay. Therefore, prioritizing this specific demographic should be the focal point of policies and public health initiatives aimed at fostering equitable oral health outcomes.

Social Inequities in Access to Dental Care in Australian Adults over Time.

INTRODUCTION: Social inequities in dental caries are reflected by both inequities in the social structures that contribute to disease severity and inequities in the provision of dental care. This study aimed to describe social differentials in the dental caries experience among Australian adults across a 13-y period and to examine if the highest magnitude of oral health inequities persisted across dental caries prevalence (decayed teeth [DT]) or its management (missing teeth [MT], filled teeth [FT]). METHODS: Data were from 2 population-based cross-sectional surveys of Australian adult oral health conducted in 2004-2006 (National Survey of Adult Oral Health-1 [NSAOH-1], n = 5,505) and 2017-2018 (NSAOH-2, n = 5,022). In each survey, representative samples of adults were obtained through a 3-stage, stratified sample design within metropolitan and regional areas in each state/territory. Clinical outcomes included the prevalence and mean of DT, MT, FT, and DMFT. Equivalized household income was grouped into approximately quartiles from low to high. RESULTS: Across all income quartiles, the mean DT and % DT >0 was higher in NSAOH-2 than in NSAOH-1. The increase in prevalence was highest in the third highest income group (prevalence difference [PD] = 8.4, from 24.1 to 32.5). Similarly, % MT >0 was lower in NSAOH-2 than in NSAOH-1 across all income groups, with the decrease most marked for the lowest income group (PD = -6.5, from 74.1 to 67.8). Across all income quartiles, % FT >0 was lower in NSAOH-2 than in NSAOH-1. The decrease was the most marked for the lowest income group (PD = -8.9, from 81.1 to 72.2). CONCLUSION: The findings confirm that although oral health inequities decreased for the most extreme management outcome of dental caries (MT), inequities increased for experience of that disease (DT) and the more conservative management of dental caries (FT). For all D, M, and F components (DMFT), inequities between the lowest and highest household income groups increased from 2004-2006 to 2017-2018. KNOWLEDGE TRANSFER STATEMENT: This study found that social inequities in oral health (experience of untreated dental caries and missing teeth) increased between the most socially advantaged and disadvantaged groups between 2004-2006 and 2017-2018. This suggests that models of dental service provision in Australia are increasingly benefitting those who can afford and access the care and who arguably need the services less than their less socially advantaged counterparts do.

Oral health profile of Australian children from different immigrant backgrounds.

OBJECTIVES: To profile the oral health of Australian children from different immigrant backgrounds. METHOD: Cross-sectional data for Australian children were obtained from the 2012-14 National Child Oral Health Study (NCOHS). Three categories of immigrant status were created based on parents' country of birth and language (non-immigrant, non-visible immigrant, and visible immigrant). Descriptive analyses reported weighted estimates for experience of dental caries, self-rated oral health, and dental services utilisation separately for children aged 5-9 years and 10-14 years. RESULTS: The sample comprised 10,610 children aged 5-9 years (3,605 from immigrant backgrounds), and 8,741 children aged 10-14 years (3,074 from immigrant backgrounds). Children from non-visible immigrant backgrounds presented worse dental service utilisation and poorer self-rated oral health than children from non-immigrant and visible immigrant families. Greater inequalities in dental caries experience were observed in the 5-9-year-olds. Untreated caries was substantially higher among visible immigrant children aged 5-9 years (38.8%, 95% CI: 35.5-42.3) than non-immigrant (24.9%, 95% CI: 23.4-26.6) and non-visible immigrant children (21.0%, 95% CI: 17.7-24.7). CONCLUSIONS: Australian children from immigrant families constitute a highly heterogeneous group with substantial discrepancies in oral health outcomes.

SEVERE NEAR REFLEX SPASM IN A HEALTHY TEENAGER. A CASE REPORT.

INTRODUCTION: Spasm of the near reflex usually includes accommodative spasm, esophoria/tropia, and different degrees of miosis. Patients usually refer to distance blurred and fluctuating vision, ocular discomfort, and headaches. The diagnosis is established with refraction with and without cycloplegia; most of the cases have a functional etiology. However, some cases require neurological conditions to be ruled out; cycloplegics have an important diagnostic and therapeutic role. PURPOSE: To describe a case of bilateral severe accommodative spasm in a healthy 14-year-old teenager. CASE PRESENTATION: A 14-year-old boy with progressive diminished visual acuity attended for YSP consultation. The diagnosis of bilateral spasm of the near reflex was made, based on a gap refraction of 9.75 D between retinoscopy with and without cycloplegia and esophoria with normal keratometry and axial length. The spasm was eliminated with 2 drops of cycloplegic in each eye separated by 15 days; no clear etiology was found other than the start of school. CONCLUSION: Clinicians should be aware of pseudomyopia, especially in children with acute changes in visual acuity, who are usually exposed to myopigenic environmental factors that induce overstimulation of the parasympathetic third cranial nerve's innervation.

Immigrants experience oral health care inequity: findings from Australia's National Study of Adult Oral Health.

BACKGROUND: Oral health service utilization contributes to positive oral health and indicates realised access to services. The study aimed to describe patterns of oral health service use among overseas-born and Australian-born populations and assess equity in access to services. METHODS: The study used data from Australia's National Study of Adult Oral Health 2017-2018 and was guided by the Aday and Andersen framework of access to health and Australia's National Oral Health Plan. Descriptive analyses of service use by perceived need, enabling and predisposing factors were compared between four groups: Australian-born and overseas-born who mainly speak English and Australian-born and overseas-born who mainly speak a language other than English. RESULTS: Overseas-born who mainly speak a language other than English experienced greater oral health care inequity, largely driven by financial difficulty (avoided care due to cost: 42% vs 27%-28%; avoided/delayed visiting due to cost: 48% vs. 37%-38%; cost prevented treatment: 32% vs. 18%-24%). The most favourable visiting patterns were among the Australian-born population who speak a language other than English. CONCLUSIONS: The study shows clear inequity experienced among immigrants in accessibility as measured through indicators of oral health care utilization and factors related to inequity, such as the ability to pay for services.

Self-rated oral and general health among Aboriginal adults in regional South Australia.

BACKGROUND: In Australia, Aboriginal adults experience higher levels of poor oral and general health than the non-Aboriginal population. This study compared self-rated oral and general health among Aboriginal adults in regional South Australia with participants in the National Survey of Adult Oral Health (NSAOH). METHODS: Data were obtained from the Indigenous Oral Health Literacy Project (IOHLP) based in South Australia. Three sub-populations from the NSAOH were utilised for comparison: National Aboriginal, National non-Aboriginal and South Australian Regional Non-Aboriginal adults. All data were standardised by age group and sex, utilising Census data. RESULTS: Just over 70% of South Australian Regional Aboriginal participants gave a rating of 'excellent, very good or good' for general health, more than 17% lower than each of the other groups. Just over 50% rated their oral health highly, 20% fewer than the proportion for each other group. Stratifying by key socio-demographic factors did not account for all differences. CONCLUSIONS: Proportionally fewer South Australian Regional Aboriginal adults had high ratings of oral and general health than the Aboriginal and non-Aboriginal adults from the national survey, indicating that national-level data might underestimate the proportion of regional Aboriginal Australians with poor oral health.

Prevalence, Extent, and Severity of Oral Health Impacts Among Adults in Rural Karnataka, India.

INTRODUCTION: Oral health affects quality of life. Many studies have investigated the factors associated with oral health-related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services. OBJECTIVES: To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y. METHODS: A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3. RESULTS: There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India. CONCLUSIONS: Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts. KNOWLEDGE TRANSFER STATEMENT: This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

Pitiriasis rubra pilaris en niños:informe de 2 casos / Pityriasis Rubra Pilaris in children: 2 case reports

RESUMEN Antecedentes: La pitiriasis rubra pilaris es una enfermedad infrecuente pápulo-escamosa crónica en la que existe un trastorno de la queratinización de la epidermis, caracterizada por pápulas foliculares hiperqueratósicas con tendencia a formar placas de coloración asalmonada, descamativas, con islas de piel sana asociadas a queratodermia palmo plantar. Presenta una distribución bimodal en la primera y sexta década de la vida, afectando a ambos sexos por igual. Su etiopatogenia es desconocida, se ha postulado una respuesta inmune anormal ante diferentes estímulos antigénicos, así como alteración del metabolismo de la vitamina A. Se ha clasificado en 6 tipos en base a su presentación, edad de inicio, curso y pronóstico, tratándose en forma tópica o sistémica. Casos clínicos: Se presentan dos casos en pacientes de 10 y 2 años de edad, con manifestaciones clínicas correspondientes al tipo juvenil circunscrito, que es el más frecuente en edad pediátrica y juvenil clásico respectivamente, con histopatología compatible y excelente respuesta al tratamiento tópico. Conclusiones: Aunque la pitiriasis rubra pilaris es una patología rara, deberá ser sospechada si el cuadro clínico es sugestivo, y si es compatible su histopatología. Debe considerarse que el tratamientotópico puede ser suficiente para lograr la resolución del cuadro.

ABSTRACT Background: Pityriasis rubra pilaris is an infrequent chronic papulosquamous disease in which there is a disorder of keratinization of the epidermis, characterized by hyperkeratotic follicular papules with a tendency to form salmon-colored, scaly plaques, with islands of healthy skin associated with palmoplantar keratoderma. It presents a bimodal distribution in the first and sixth decades of life, affecting both sexes equally. Its etiopathogenesis is unknown, an abnormal immune response has been postulated to different antigenic stimuli, as well as alteration of the metabolism of vitamin A. It has been classified into 6 types based on its presentation, age of onset, course and prognosis, being treated appropriately topical or systemic. Clinical cases: Two cases of 10 and 2 years of age are presented, with clinical manifestations corresponding to the circumscribed juvenile type, which is the most frequent in pediatric and classic juvenile age respectively, with compatible histopathology and excellent response to topical treatment. Conclusions: Although pityriasis rubra pilaris is a rare pathology, it should be suspected if the clinical picture is suggestive and its histopathology is compatible. It should be considered that topical treatment may be sufficient to achieve resolution of the condition.

Factors associated with ever use of mammography in a limited resource setting. A mixed methods study.

OBJECTIVE: To evaluate facilitators and barriers influencing mammography screening participation among women. DESIGN: Mixed methods study. SETTING: Three hospital catchment areas in Hidalgo, Mexico. PARTICIPANTS: Four hundred and fifty-five women aged 40-69 years. INTERVENTION: Three hundred and eighty women completed a survey about knowledge, beliefs and perceptions about breast cancer screening, and 75 women participated in semi-structured, in-person interviews. Survey data were analyzed using logistic regression; semi-structured interviews were transcribed and analyzed using elements of the grounded theory method. MAIN OUTCOME MEASURE: Women were categorized as never having had mammography or having had at least one mammogram in the past. RESULTS: From survey data, having had a Pap in the past year was associated with ever having had breast screening (odds ratio = 2.15; 95% confidence interval 1.30-3.54). Compared with never-screened women, ever-screened women had better knowledge of Mexican recommendations for the frequency of mammography screening (49.5% vs 31.7% P < 0.001). A higher percentage of never-screened women perceived that a mammography was a painful procedure (44.5% vs 33.8%; P < 0.001) and feared receiving bad news (38.4% vs 22.2%; P < 0.001) compared with ever-screened women. Women who participated in semi-structured, in-person interviews expressed a lack of knowledge about Mexican standard mammographic screening recommendations for age for starting mammography and its recommended frequency. Women insured under the 'Opportunities' health insurance program said that they are referred to receive Pap tests and mammography. CONCLUSIONS: Local strategies to reduce mammogram-related pain and fear of bad news should work in tandem with national programs to increase access to screening.

VALORACIÓN DE ENERGÍA DIGESTIBLE DE LA GLICERINA CRUDA PROVENIENTE DE ACEITE DE PALMA -Elaeis guineensis- PARA CERDOS EN CRECIMIENTO EN FUNCIÓN DEL NIVEL DE ALMIDÓN DE MAÍZ EN LA DIETA / VALUATION OF DIGESTIBLE ENERGY OF CRUDE GLYCERIN FROM PALM OIL -Elaeis guineensis- FOR GROWING PIGS BASED ON DIETARY CORN STARCH LEVEL

Para determinar la energía digestible aparente (EDA) de la glicerina cruda (GC) proveniente del aceite de palma (Elaeis guineensis) en cerdos se realizaron dos experimentos (E). En E1 se determinó la EDA para GC con la técnica de la bolsa móvil de nailon (TBMN) utilizando ocho cerdos castrados con cánula duodenal. En E2 se determinaron la EDA y la energía metabolizable aparente (EMA) para GC, por el método convencional con indicador (MCI), con 10 cerdos castrados ubicados en jaulas metabólicas. En E1 y E2 se evaluaron, en un arreglo factorial 2 x 5, dos niveles de almidón de maíz (NA) en la dieta, 10% (NA10) y 12% (NA12), y cinco niveles de sustitución con GC (0%, 2,5%, 5,0%, 7,5% y 10%) en E1 en un diseño completo al azar y en E2 en un diseño de cuadrado latino. Para TBMN y MCI los datos se analizaron mediante regresión lineal múltiple y el metabolismo del nitrógeno en MCI como un diseño de cuadrado latino utilizando los módulos REG y GLM del paquete SAS. Por TBMN no hubo efectos (P > 0,05) del NA sobre la EDA de GC. La EDA de GC se calculó en 3.251 kcal/kg MS. La EDA de GC en MCI dependió de NA (P < 0,001) estimándose en 4.427,3 y 3.769,3 Kcal/kg MS para NA10 y NA12, respectivamente. Hubo interacción (P < 0,001) entre NA y GC para la cantidad de nitrógeno digestible, se redujo cuando GC aumentó en NA12 y aumentó en NA10. Otros parámetros del metabolismo nitrogenado no se vieron afectados (P > 0,05). Los resultados de EDA corregidos por NA con MCI mostraron correlación alta (R2 = 0,82) con TBMN. Con MCI se pudo establecer que el aumento en NA en la dieta reduce la EDA de GC.

To determine the apparent digestible energy (EDA) of crude glycerin (GC) from palm oil (Elaeis guineensis) in pigs two experiments (E) were performed. In E1, EDA was determined to GC, with the technique of mobile nylon bag (TBMN) using eight barrows with duodenal cannula. In E2, EDA, EMA to GC was determined by the conventional method with indicator (MCI) with 10 barrows placed in metabolic cages. In E1 and E2 were evaluated in 2 x 5 factorial arrangement, two levels of corn starch (NA) in the diet, 10 (NA10) and 12% (NA12), and five levels of replacement by GC (0%, 2.5%, 5%, 7.5% and 10%), in E1 as a completely randomized design and in E2 as a Latin square design. For MCI and TBMN, data were analyzed using multiple linear regression and nitrogen metabolism in MCI as a Latin square design using the GLM and REG modules of SAS. By TBMN there was no effect (P > 0.05) in the NA on the EDA of GC. EDA of GC was calculated at 3251 kcal/kg DM. EDA of GC in the MCI depended NA (P < 0.001), estimated at 4427.3 and 3769.3 Kcal/kg MS for NA10 and NA12, respectively. Interaction (P < 0.001) between NA and GC for the amount of digestible nitrogen was observed, was reduced when GC increased by NA12 and increased by NA10. Other nitrogen metabolism parameters were not affected (P > 0.05). The results of EDA corrected by NA with MCI showed high correlation (R² = 0.82) with TBMN. By MCI was established that increased in NA reduced the EDA of GC.

Circulating leptin and adiponectin, and breast density in premenopausal Mexican women: the Mexican Teachers' Cohort.

PURPOSE: Leptin and adiponectin are produced by the adipose tissue. Mammographic density (MD) is one of the strongest predictors of breast cancer (BC) and is highly influenced by adiposity. How the interplay between MD, obesity, and obesity-related biomarkers influences BC risk, however, is still unknown, especially in premenopausal women, where adiposity seems to be protective for BC. The aim of the present study was to explore the association between circulating leptin, adiponectin, and their ratio, with MD in Mexican premenopausal women who are part of the large Mexican Teachers' Cohort (MTC). METHODS: A subsample of 2,084 women from the MTC participated in a clinical evaluation. Of them, 574 premenopausal women were randomly selected, from four MD strata. Serum leptin and adiponectin concentrations were measured by immunoassays. Multivariate regression analyses were performed to compare means of MD by quartiles of adipokines and their ratio. RESULTS: High leptin and leptin/adiponectin ratio levels were significantly associated with lower percentage MD and higher absolute and non-absolute dense tissue areas. High adiponectin levels were significantly associated with lower absolute dense and non-dense tissue areas, but not with percentage MD. After adjustment for BMI, only the associations between percentage MD and absolute non-dense tissue area with leptin remained statistically significant. CONCLUSIONS: Leptin, adiponectin, and their ratio were associated with MD; however, only the positive association with leptin seemed to be independent from overall obesity.

Objective: To identify factors related to habits and behaviors of overweight adults living in three urban areas of Manizales, La Dorada and Chinchiná during 2015. Materials and Methods: This was a qualitative study with a convenience sample of 23 adults. The procedure for data collection focused on in-depth interviews. An interview guide was developed and a pilot test was conducted to optimize the thematic sequence in the interaction with the participants. Data analysis was done using the software Dedosse. In the coding of fragments and categorization, open coding was used, naming live codes of sentences and procedures were discussed among researchers to achieve consensus. Results: Four categories of factors related to habits and behaviors were identified: unhealthy habits and behaviors in an obesogenic environment, nutritional information, rational and irrational behavior / attitudes, and imaginary and health care services. Conclusions: Sedentary lifestyle, obesogenic environment, absence of public policies for the control of overweight, and low supply and availability of programs, services, and nutritionists are identified as factors related to habits and behaviors of overweight adults in Caldas.

Does early-life family income influence later dental pain experience? A prospective 14-year study.

BACKGROUND: The aim of this study was to investigate the association between early-life family income and dental pain experience from childhood to early adulthood. METHODS: Data came from a 14-year prospective study (1991/1992-2005/2006) carried out in South Australia, which included children and adolescents aged 4-17 years (N = 9875) at baseline. The outcome was dental pain experience obtained at baseline, 14 years later in adulthood and at a middle point of time. The main explanatory variable was early-life family income collected at baseline. RESULTS: The prevalence of dental pain was 22.8% at baseline, 19.3% at 'middle time' and 39.3% at follow up. The proportion of people classified as 'poor' at baseline was 27.7%. Being poor early in life was significantly associated with dental pain at 14-year follow up (odds ratio = 1.45; 95% confidence interval = 1.27-1.66). CONCLUSIONS: Early-life relative poverty is associated with more frequent dental pain across the 14-year follow up and may be a key exposure variable for later dental conditions.

Periodontal therapy and glycaemic control among individuals with type 2 diabetes: reflections from the PerioCardio study.

OBJECTIVES: Diabetes mellitus and periodontal disease are highly prevalent among Indigenous Australian adults. Untreated periodontitis impacts glycaemic control in people with diabetes. The aim of this study was to report on the effect of periodontal therapy on glycaemic control among people with obesity. METHODS: This subgroup analysis is limited to 62 participants with diabetes from the original 273 Aboriginal Australian adults enrolled into the PerioCardio study. Intervention participants received full-mouth non-surgical periodontal scaling during a single, untimed session while controls were untreated. Endpoints of interest included change in glycated haemoglobin (HbA1c), C-reactive protein (CRP) and periodontal status at 3 months post-intervention. RESULTS: There were more females randomized to the treatment group (n = 17) than control (n = 10) while the control group had a higher overall body mass index (BMI) [mean (SD)] 33.1 (9.7 kg m-2 ) versus 29.9 (6.0 kg m-2 ). A greater proportion of males were followed up at 3 months compared to females, P = 0.05. Periodontal therapy did not significantly reduce HbA1c: ancova difference in means 0.22 mmol mol-1 (95% CI -6.25 to 6.69), CRP: ancova difference in means 0.64 (95% CI -1.08, 2.37) or periodontal status at 3 months. CONCLUSIONS: Non-surgical periodontal therapy did not significantly reduce glycated haemoglobin in participants with type 2 diabetes. Reasons are likely to be multifactorial and may be influenced by persistent periodontal inflammation at the follow-up appointments. Alternatively, the BMI of study participants may impact glycaemic control via alternative mechanisms involving the interplay between inflammation and adiposity meaning HbA1c may not be amenable to periodontal therapy in these individuals.

Inequalities in Indigenous Oral Health: Findings from Australia, New Zealand, and Canada

The objective was to compare absolute differences in the prevalence of Indigenous-related inequalities in dental disease experience and self-rated oral health in Australia, Canada, and New Zealand. Data were sourced from national oral health surveys in Australia (2004 to 2006), Canada (2007 to 2009), and New Zealand (2009). Participants were aged ≥18 y. The authors measured age- and sex-adjusted inequalities by estimating absolute prevalence differences and their corresponding 95% confidence intervals (95% CIs). Clinical measures included the prevalence of untreated decayed teeth, missing teeth, and filled teeth; self-reported measures included the prevalence of "fair" or "poor" self-rated oral health. The overall pattern of Indigenous disadvantage was similar across all countries. The summary estimates for the adjusted prevalence differences were as follows: 16.5 (95% CI: 11.1 to 21.9) for decayed teeth (all countries combined), 18.2 (95% CI: 12.5 to 24.0) for missing teeth, 0.8 (95% CI: -1.9 to 3.5) for filled teeth, and 17.5 (95% CI: 11.3 to 23.6) for fair/poor self-rated oral health. The I2 estimates were small for each outcome: 0.0% for decayed, missing, and filled teeth and 11.6% for fair/poor self-rated oral health. Irrespective of country, when compared with their non-Indigenous counterparts, Indigenous persons had more untreated dental caries and missing teeth, fewer teeth that had been restored (with the exception of Canada), and a higher proportion reporting fair/poor self-rated oral health. There were no discernible differences among the 3 countries.

Biliary Complications After Liver Transplantation: Incidence, Risk Factors and Impact on Patient and Graft Survival.

INTRODUCTION: Biliary complications (BC) are one of the most frequent surgical complications after liver transplantation. They include biliary stenosis, leaks, choledocolitiasis and sphincter of Oddi dysfunction. These complications can cause graft dysfunction, retrasplantation, or even death. The purpose of this study was to identify factors related to BC. MATERIALS AND METHODS: The medical records of all adult patients who underwent their first liver transplantation in our institution from 2005 to 2013 were reviewed, and any BC that required management was recorded. Cumulative incidence of BC was estimated using Kaplan-Meier. Patient and graft survival was compared using the log-rank test. The Cox regression model was used to establish associated factors. RESULTS: Of the 236 patients who underwent liver transplantation, 41 patients (17.8%) developed BC. Cumulative incidence was 12.9%, 17.2%, and 20%, after 1, 3 and 5 years of the transplantation, respectively. Twenty-six cases of biliary stenosis, 11 of leaks, and 4 of choledocolitiasis were identified. Most patients were managed endoscopically (82.9%). There were no differences in patient or graft survival. DISCUSSION: Biliary stenosis is the most frequent BC. Patients with higher risk of BC were of blood type AB (P < .001), had viral hepatitis (P = .049), or had alcoholic cirrhosis (P = .036). The success with the endoscopic treatment reduced the need for surgical interventions. CONCLUSIONS: The incidence of BC in our institution is comparable with the incidence reported in other institutions. Further prospective studies with larger series of patients are warranted to identify other factors associated with development of BC.

Knowledge and recommendations regarding breast cancer early screening in an upper middle income country: Primary and secondary health care professionals.

OBJECTIVE: To compare the current breast cancer prevention and control Mexican standard with recommendations that health care professionals provide to women for breast self-exams, clinical breast exams and mammography, as well as health care professional knowledge of the risk factors for and main clinical signs of the disease. METHODS: In 2012, using a cross-sectional design, trained interviewers surveyed health care providers in a sample of 798 medical units, of which 756 corresponded to the first and second levels of medical care. One health care professional from each unit was interviewed for the study. The sampling method was systematic and representative of the national and regional levels. Relative frequencies and 95% confidence intervals (CI) were obtained using the weighting factor assigned to each medical unit. RESULTS: Regarding the indicator about recommendations provided to the population regarding early screening for and risk factors and clinical signs of breast cancer, the average number of health care professional responses in accordance with the Mexican standard was 10.7 (95% CI 10.0-11.4) out of a maximum of 28 points, which corresponds to an average rate of 38.2% of responses (95% CI 35.6-40.8). The percentage of correct answers increased in all areas of breast exam knowledge as training hours in the previous year increased. CONCLUSIONS: Health care professionals are unaware of the current standards on breast cancer; therefore, these recommendations are not routinely translated into health care practice, which is a barrier to increasing the coverage of screening programs in health care services.

Comparison of Fe-Al-modified natural materials by an electrochemical method and chemical precipitation for the adsorption of F- and As(V).

The adsorption of fluoride and arsenic ions by modified natural materials may have an impact on the removal of F- and As(V) from waters. In this work, a zeolitic material and pozzolan (commonly known as pumicite) were modified with aluminium an iron by an electrochemical method and chemical precipitation, respectively. The adsorbents were characterized by X-ray diffraction, scanning electron microscopy with energy X-ray disperse spectroscopy analysis and the point of zero charge (pHzpc). F- and As(V) adsorption properties of both materials were investigated. Adsorption kinetic data were best fitted to pseudo-second-order model and equilibrium data to the Langmuir isotherm model. The highest F- and As(V) sorption capacities were obtained for modified zeolitic (0.866 mg/g) and pozzolan (3.35 mg/g) materials, respectively, with initial F- or As(V) concentrations of 10 mg/L. It was found that the unmodified materials did not show either adsorption of F- ions or As(V), which indicated that Al and Fe in the adsorbents are responsible for the adsorption of these ions. In general, both modified materials show similar capacities for the adsorption of F- and As(V).

The relationship between maternal smoking during pregnancy and parental-reported experience of dental caries in Indigenous Australian children.

OBJECTIVE: This study aimed to test the association between maternal smoking during pregnancy and parental-reported experience of dental caries in Indigenous Australian children. METHODS: Data were from the Longitudinal Study of Indigenous Children (LSIC); a population-based cohort study in Australia. Participants were 1,687 Indigenous Australian children aged 5 or less. Biological, social and behavioural variables were tested using log-linear modelling with binomial regression to determine the association with parental-reported experience of dental caries. Markov Chain Monte Carlo methods were used for multiple imputation of missing data. RESULTS: Overall 25.8% of Indigenous Australian children had dental caries as reported by a carer. In the multivariable model, increased prevalence of parental-reported caries was significantly associated with low maternal education levels (RR=1.60, 95%CI 1.17,2.20) and high sugar consumption (RR= 1.60, 95%CI 1.26,2.02). In the group of children whose mothers smoked tobacco during pregnancy, the association with parent-reported dental caries approached the threshold of significance, but was not significantly associated with caries status in children (RR=1.19, 95%CI 0.99,1.43). After multiple imputation, the most significant association was evident in children of the least educated mothers (RR=1.57, 95%CI 1.25,1.95), breastfeeding more than 12 months (RR=1.26, 95%CI 1.01,1.56), sweet intake more than 30% (RR=1.42, 95%CI 1.15,1.74) and 20-30% (RR=1.29 95%CI 1.04,1.59) and residing in outer regional (RR=1.56, 95%CI 1.19,2.05) or inner regional locations (RR=1.50, 95%CI 1.19,1.88). Mothers' tobacco smoking status showed a weak association with parent-reported dental decay (RR=1.42, 95%CI 1.20,1.68). CONCLUSION: This study suggests there is a weak association between maternal smoking during pregnancy and prevalence of parentally-reported dental caries in Indigenous Australian children.
