RESUMO

BACKGROUND/AIM: Orofacial and dental injuries in athletes, both amateur and professional, are highly prevalent. Mouthguards are devices to prevent this type of injury; however, athletes believe that the mouthguard limits their performance in the game and decreases their confidence. This study analyzed the perception that some basketball, rugby and soccer players from a public university in Colombia have about the use of mouthguards. MATERIAL AND METHODS: Comprehensive qualitative study with ethnographic approach. Twenty-nine players participated. Three data collection tools were used: semi-structured interviews, field diary and discussion groups. Content analysis was carried out using a categorical matrix and triangulation of sources. RESULTS: Participants perceive the mouthguard as a device to prevent orofacial and dental injuries, but unattractive to wear during competitions. Factors that determine the use or non-use of the mouthguard are player comfort and adaptability, communication and economic cost. CONCLUSIONS: Players' perception of mouthguards in soccer, basketball and rugby is multifactorial, and is mediated by the idea of contact risk during sports practice, prevention of orofacial injuries, influence on sports performance, comfort and adaptability to the mouthguard.

RESUMO

BACKGROUND: Obesity in Mexico is an alarming problem that has been increasing in recent decades. Dietary factors make this pathology more common at younger ages and closely related to oral health. This study attempts to investigate the association between the oral health status of a Mexican population in the state of Yucatan and their dietary habits. OBJECTIVE: This study explores the relationship between oral health-related quality of life and adherence to the Mediterranean diet in a disadvantaged population in the state of Yucatan, Mexico. METHODS: The research was conducted in July 2023 in Merida, Yucatan (Mexico). The sample consisted of 109 individuals aged between 4 and 72 years old. Data analysis focused on factors such as body mass index (BMI), oral health-related quality of life, and adherence to the Mediterranean diet. RESULTS: A notable presence of caries is observed in individuals with low adherence to the Mediterranean diet (Correlation coefficient 0.040, p=0.682). This underscores the potential interaction between oral health, obesity, and dietary habits. The mean Oral Health-Related Quality of Life (OHIP-14Sp) score was 13.19 ±13.57, median 8.00. CONCLUSIONS: This research adds to the increasing evidence that highlights the significance of a balanced diet in enhancing the oral quality of life for people. More research is necessary to explore preventive measures and treatment to raise awareness about oral health within the community.

ANTECEDENTES: La obesidad en México es un problema alarmante que ha ido en aumento en las últimas décadas. Los factores dietéticos hacen que esta patología sea más común en edades más tempranas y muy relacionada con la salud bucal. Este estudio intenta investigar la asociación entre el estado de salud bucal de una población mexicana en el estado de Yucatán y sus hábitos alimentarios. OBJETIVO: Este estudio explora la relación entre la calidad de vida relacionada con la salud bucal y la adherencia a la dieta mediterránea en una población desfavorecida del estado de Yucatán, México. Métodos: La investigación se realizó en julio de 2023 en Mérida, Yucatán (México). La muestra estuvo compuesta por 109 individuos con edades comprendidas entre 4 y 72 años. El análisis de los datos se centró en factores como el índice de masa corporal (IMC), la calidad de vida relacionada con la salud bucal y la adherencia a la dieta mediterránea. RESULTADOS: Se observa una notable presencia de caries en individuos con baja adherencia a la dieta mediterránea (coeficiente de correlación 0,040, p=0,682). Esto subraya la posible interacción entre la salud bucal, la obesidad y los hábitos alimentarios. La puntuación media de la calidad de vida relacionada con la salud bucal (OHIP-14Sp) fue 13,19 ± 13,57, mediana 8,00. CONCLUSIONES: Esta investigación se suma a la creciente evidencia que resalta la importancia de una dieta equilibrada para mejorar la calidad de vida bucal de las personas. Es necesaria más investigación para explorar medidas preventivas y tratamientos para crear conciencia sobre la salud bucal dentro de la comunidad.

RESUMO

BACKGROUND: The use of technologies has had a significant impact on patient safety and the quality of care and has increased globally. In the literature, it has been reported that people die annually due to adverse events (AEs), and various methods exist for investigating and measuring AEs. However, some methods have a limited scope, data extraction, and the need for data standardization. In Brazil, there are few studies on the application of trigger tools, and this study is the first to create automated triggers in ambulatory care. OBJECTIVE: This study aims to develop a machine learning (ML)-based automated trigger for outpatient health care settings in Brazil. METHODS: A mixed methods research will be conducted within a design thinking framework and the principles will be applied in creating the automated triggers, following the stages of (1) empathize and define the problem, involving observations and inquiries to comprehend both the user and the challenge at hand; (2) ideation, where various solutions to the problem are generated; (3) prototyping, involving the construction of a minimal representation of the best solutions; (4) testing, where user feedback is obtained to refine the solution; and (5) implementation, where the refined solution is tested, changes are assessed, and scaling is considered. Furthermore, ML methods will be adopted to develop automated triggers, tailored to the local context in collaboration with an expert in the field. RESULTS: This protocol describes a research study in its preliminary stages, prior to any data gathering and analysis. The study was approved by the members of the organizations within the institution in January 2024 and by the ethics board of the University of São Paulo and the institution where the study will take place. in May 2024. As of June 2024, stage 1 commenced with data gathering for qualitative research. A separate paper focused on explaining the method of ML will be considered after the outcomes of stages 1 and 2 in this study. CONCLUSIONS: After the development of automated triggers in the outpatient setting, it will be possible to prevent and identify potential risks of AEs more promptly, providing valuable information. This technological innovation not only promotes advances in clinical practice but also contributes to the dissemination of techniques and knowledge related to patient safety. Additionally, health care professionals can adopt evidence-based preventive measures, reducing costs associated with AEs and hospital readmissions, enhancing productivity in outpatient care, and contributing to the safety, quality, and effectiveness of care provided. Additionally, in the future, if the outcome is successful, there is the potential to apply it in all units, as planned by the institutional organization.

RESUMO

OBJECTIVES: Research trends concerning hearing loss within teen rural populations are limited and current evidence suggests that extended high-frequency audiometry can be a sensitive tool to detect subclinical hearing loss. Moreover, current research emphasises the importance of representing different ethnic populations in science. This study aimed to determine the prevalence of acquired hearing loss through conventional pure-tone (0.25-8 kHz) and extended high frequency (EHF) (9-20 kHz) audiometry in Afro-Colombian adolescents from a rural area in Colombia. DESIGN: Observational, cross-sectional study. PARTICIPANTS: 230 Afro-Colombian adolescents aged 13-17 years who attended high school in a rural population from Cartagena, Colombia. INTERVENTIONS: Otoscopic examination, conventional (0.25-8 kHz) and EHF (9-20 kHz) audiometry tests were performed during February-March 2021. Sociodemographic and associated factor questionnaires were also applied to assess probable factors associated with EHF hearing loss. MAIN OUTCOME MEASURES: Prevalence of acquired hearing loss using conventional and EHF audiometry, and factors associated with hearing loss. RESULTS: Of 230 adolescents who met the eligibility criteria, 133 (57.82%) were female. The mean age was 15.22 years (SD: 1.62). The prevalence of hearing loss in at least one ear assessed with conventional audiometry was 21.30% and with EHF audiometry 14.78%. The main abnormal otoscopic findings included: neotympanum (1.30%), myringosclerosis (0.87%) and monomeric scars (0.43%). Factors associated with a higher probability of EHF hearing loss found through logistic regression were older age (prevalence ratio (PR): 1.45; 95% CI 1.16 to 1.80), attending the 'Picó' four or more times a month (PR: 6.63; 95% CI 2.16 to 20.30), attending bars more than three times a month (PR: 1.14; 95% CI 1.03 to 1.59) and self-reported hearing difficulties (PR: 1.24; 95% CI 1.22 to 4.05). CONCLUSIONS: Our results suggest that acquired hearing loss is already widespread among this young rural population.

RESUMO

Autism comes from the Greek word auto, which means "self." Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social interaction and communication. Dental treatment in patients with ASD can be challenging due to their behavior. Therefore, this review discusses preventive treatment techniques for pediatric patients with ASD at the dental office, as the prevalence of children with autism is growing. Thus, dentists would face more patients with autism in their daily practice. Regarding treatment protocols, they would require specialized attention in dental management. Information was searched in the following databases: PubMed, SciELO, Redalyc, Elsevier, and the International Association of Paediatric Dentistry (IAPD). The descriptors used were: Pediatric Dentistry, Autism, ASD, Autism Spectrum Disorder, and Management of the autistic patient.

RESUMO

INTRODUCTION: Understanding suicide in more isolated territories is a challenge because of the entanglement of cultural identity with historical, geographical and sociocultural specificities. This knowledge is a necessary precondition for the implementation of targeted prevention strategies in regions such as the French overseas territories (FOT), where data concerning suicidal risk factors is still incomplete. We aim to untangle sociocultural and clinical suicide risk factors by integrating a novel anthropological and psycholinguistic approach into the psychological autopsy method. This article describes the protocol of the clinical study 'Contribution of Psychological Autopsy to the Understanding of Suicidal Behaviours in Overseas France' (AUTOPSOM study), designed to identify common or new specific suicide risk factors in four FOT. METHODS AND ANALYSIS: A multicentre epidemiological study will be carried out in four FOTs (French Polynesia, Martinique, La Reunion and French Guiana) and at a comparison site in mainland France (La Somme). The methodology will be based on a mixed-methods (quantitative and qualitative) approach using a psychological autopsy to collect clinical data and life events in the deceased's life. We implemented an exploratory multimethod strategy that combines a succession of epidemiological, anthropological, psycholinguistic and psychological methods with a semiautomated analysis of the discourse of relatives bereaved by suicide. ETHICS AND DISSEMINATION: The study protocol (first version) was approved by the French Ethics Committee (CPP OUEST II, approval #22.04267.000122) and the Ethics Committee of French Polynesia (JOPF of 5 April 2022; CEPF opinion n°91 of 29 March 2022). The overall results and the perspectives established at the end of the study will be communicated to the bereaved relatives according to their will and serve for local suicide prevention purposes.

Conclusions: The conditioning factors of varicose veins are of a regular proportion in nursing professionals at the San Juan de Dios Hospital in Pisco, and preventive measures are more prevalently regular, with significant gaps showing the need to improve preventive measures at a good level to deal with the large proportion of conditioning factors of varicose veins in this population group.

RESUMO

INTRODUCTION: Our goal was to better understand the health care utilization of patients with spina bifida (SB) by evaluating length of hospital stay (LOS) as well as identifying what characteristics within the SB population are contributing to shorter or longer LOS. METHODS: By querying the Department of Health Care Access and Information database of all encounters at California-licensed hospitals from January 1995 through December 2017, this study analyzed LOS as a measure of health care utilization. Patients with SB were identified using the International Classification of Diseases-9 and -10 coding system, and the data collected for both SB and control cohorts were compared using linear and logistic regression models. RESULTS: Patients with SB spent a mean LOS of 7.3 days compared to 4.7 days among the control cohort (P < .001). In multivariable analysis, SB was found to be an independent predictor of longer LOS. Within the SB encounters, increasing comorbidities and nonprivate insurance were associated with longer LOS, while being female and Hispanic were associated with a shorter LOS. CONCLUSIONS: SB is an independent predictor of longer LOS when compared to the control cohort. These findings highlight the importance of understanding the preventive health care access and needs of the vulnerable SB population to decrease hospital utilization rates.

RESUMO

Sarcopenia is defined by the presence of decreased skeletal muscle mass, strength, and functionality in older people. Multicomponent interventions represent an alternative to non-pharmacological treatment for preventing disease progression. This study aimed to evaluate the effects of a multicomponent intervention approach in women at risk of sarcopenia. METHODS: A quasi-experimental pilot study of 12 weeks was conducted, with 24 sessions of dancing and resistance exercises and 12 sessions of nutritional education. The outcomes were changes in muscle mass, grip strength, gait speed, and body composition. The project was registered on Clinical Trials: NCT06038500 (14 September 2023). RESULTS: Twelve women aged 55-75 years participated in this study; after the intervention, changes were found in the following variables: grip strength, from 18.70 (17.98-19.23) at baseline to 21.57 (20.67-23.16) kg (p = 0.002); gait speed, from 0.95 (0.81-1.18) at baseline to 1.34 (1.20-1.47) m/s (p = 0.003); and hip circumference, from 99.75 (94.75-110.37) at baseline to 97.65 (93.92-109.50) cm (p = 0.023). Other measurements that appeared without changes were appendicular skeletal muscle mass, from 21.17 (18.58-22.33) at baseline to 20.77 (18.31-22.39) kg (p = 0.875), and the appendicular skeletal muscle mass index, from 8.64 (8.08-9.35) at baseline to 8.81 (7.91-9.38) kg/m2 (p = 0.875) after the intervention. CONCLUSIONS: The three-month multicomponent intervention in women at risk of sarcopenia improved their grip strength and gait speed.

RESUMO

Objective: To systematically review studies examining the effects of home-visiting preventive parenting programs (HV-PPs) on improving the quality of mother-child interactions in early childhood. Method: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol, we identified 3,586 studies published between 2018 and 2022 by searching the following databases: PubMed, Web of Science, BVS/LILACS, SciELO, and PsycNET/PsycINFO. After applying the eligibility criteria, 17 articles were selected for review. Results: Most studies were conducted in high-income countries (53%) and the remainder were conducted in upper-middle-income countries, predominantly using a randomized controlled trial design and with strong methodological quality. The 17 studies applied 13 different HV-PPs, predominantly using video feedback, based on various dosages and schedules. Most studies (77%) showed significant positive effects on mother-child interactions by improving mainly positive maternal behaviors (e.g., sensitivity and responsiveness). Positive effects occurred independent of the study design, sample characteristics, measures, and constructs assessed. However, the findings suggest that the combination of fewer than six sessions, durations shorter than three months, and a very early start did not impact mother-child interactions, as expected. Few studies have explored negative maternal behaviors, children's behaviors, and dyadic interactions such as mutuality and synchrony. Conclusions: HV-PPs positively impacted mother-child interactions in early childhood despite the large heterogeneity across program designs, outcome measures, and overlapping constructs. Based on the results, we discuss the practical and economic implications of using parenting programs as a preventive approach.

RESUMO

El objetivo de la odontología preventiva es reducir al máximo el riesgo de desarrollar enfermedades bucodentales; para lograrlo, existen múltiples métodos como la aplicación de flúor, así como la colocación de selladores de fosas y fisuras. Los selladores son materiales resinosos capaces de cubrir y eliminar las retenciones de las fosas y fisuras características de la anatomía oclusal. Si bien los selladores son ampliamente utilizados en pacientes pediátricos, erróneamente se cree que su colocación está contraindicada en adultos. Los selladores son métodos preventivos capaces de beneficiar a cualquier paciente que los necesite, independientemente de su edad. El objetivo de este artículo es analizar y esclarecer las indicaciones y contraindicaciones de los selladores de fosas y fisuras en pacientes adultos (AU)

The objective of preventive dentistry is to minimize the risk of developing oral diseases and to achieve this there are multiple methods such as the application of fluoride, as well as the placement of pit and fissure sealants. Sealants are resinous materials capable of covering and eliminating retentions in pits and fissures characteristic of occlusal anatomy. Although sealants are widely used in pediatric patients, it is erroneously believed that their placement is contraindicated in adult patients. Sealants are preventive methods capable to benefiting any patient who needs them regardless of age. The aim of this article is to analyze and clarify the indications and contraindications of pit and fissure sealants in adult patients (AU)

RESUMO

BACKGROUND: Limited evidence exists on the population attributable fraction (PAF) of cancer cases and deaths in Latin America. In Peru several studies have been published regarding the PAF of various risk factors and their associated diseases. The objective of this study was to estimate the fraction of cancer cases and deaths attributable to potentially modifiable risk factors in Peru in 2018, before the COVID-19 pandemic in the population of 15 years old and older. METHODS: An ecological study was conducted using the prevalence of exposure of the Peruvian population to modifiable risk factors for cancer, the relative risk associated with each factor, and the number of cancer cases and deaths in 2018 as inputs. We used the Parkin formula with a Montecarlo statistical simulation model to calculate the PAF and confidence intervals. The number of new cancer cases and deaths attributed to each risk factor was determined by multiplying the number of cases and deaths in each gender by the PAF of each risk factor. FINDINGS: In Peru, 38.5% of new cases (34.5% in men and 42% in women) and 43.4% of cancer-related deaths (43.4% in men and 43.4% in women) were attributable to modifiable risk factors. The number of cancers attributable was 25,308 (10,439 in men and 14,869 in women) and the number of deaths attributable to cancer was 14,839 (6,953 in men and 7,886 in women). The predominant modifiable risk factors contributing to the highest number of cases and deaths were HPV infection (4,563 cases, 2,409 deaths), current tobacco use (3,348 cases, 2,180 deaths), and helicobacter pylori infection (2,677 cases, 1,873 deaths). Among the risk factors, oncogenic infections constituted the group with the highest PAF (16.6% for cases, 19.2% for deaths) followed by other unhealthy lifestyle factors (14.2% for cases, 16.7% for deaths), tobacco (7.2% for cases, 7.2% for deaths) and ultraviolet radiation (0.5% for cases, 0.3% for deaths). CONCLUSIONS: Prior to the COVID-19 pandemic, 38.5% of cancer cases and 43.4% of cancer-related deaths in Peru were linked to modifiable risk factors in the population of 15 years old and older. Most preventable cancer cases and deaths were related to oncogenic infections, primarily caused by HPV and helicobacter pylori, followed by tobacco and obesity.

RESUMO

Biosecurity refers to a set of practices that prevents and/or controls the introduction, spread, and elimination of harmful biological agents in a production system. In this study, we aimed to survey the biosecurity practices and determine their correlation with the size of production systems. A biosecurity assessment form was provided to 69 farms in the Campos Gerais region of Paraná, Brazil. The questionnaire was divided into two sections: general and bovine viral diarrhea virus- and bovine herpesvirus type-1-specific sections. The general section covered topics on traffic control, quarantine and animal isolation, hygiene practices, carcass disposal, and disease monitoring/control. The specific section consisted of questions on the reproductive and respiratory factors, use of antimicrobials, and vaccination schedule. The 69 farms were also classified into small (≤ 61), medium (62-201), and large (≥ 202) size farms based on the number of lactating cows. Moreover, multiple correspondence analysis (MCA) was performed between the biosecurity measures and farm size. The main risk factors and variability were related to the traffic control of people, animals, and vehicles/equipment, animal quarantine/isolation, and hygiene practices. MCA revealed that the small farms exhibited a lack of biosecurity measures, including those related to traffic control, animal quarantine, and hygiene. In medium-size farms, contact between bovine animals of different ages and difficulty in animal isolation in the quarantine system were among the main risk factors. In contrast, isolation of sick animals was easy, but the need to frequently purchase cattle was an important risk factor in large farms. These results highlight the relationship between biosecurity measures and farm size, providing valuable insights for the development of better biosecurity plans for production systems.

RESUMO

Traumatic muscle injuries (TMIs) and muscle pain (MP) negatively impact athletes' performance and quality of life. Both conditions have a complex pathophysiology involving the interplay between genetic and environmental factors. Yet, the existing data are scarce and controversial. To provide more insights, this study aimed to investigate the association of single-nucleotide polymorphisms (SNPs) previously linked to athletic status with TMI and MP after exercise among Brazilian high-performance athletes from different sports modalities (N = 345). The impact of important environmental determinants was also assessed. From the six evaluated SNPs (ACTN3 rs1815739, FAAH rs324420, PPARGC1A rs8192678, ADRB2 rs1042713, NOS3 rs1799983, and VDR rs731236), none was significantly associated with TMI. Regarding MP after exercise, ACTN3 rs1815739 (CC/CT vs. TT; adjusted odds ratio (aOR) = 1.90; 95% confidence interval (95%Cl), 1.01-3.57) and FAAH rs324420 (AA vs. AC/CC; aOR = 2.30; 95%Cl, 1.08-4.91) were independent predictors according to multivariate binomial analyses adjusted for age (≥23 vs. <23 years), sex (male vs. female), and tobacco consumption (yes vs. no). External validation is warranted to assess the predictive value of ACTN3 rs1815739 and FAAH rs324420. This could have implications for prophylactic interventions to improve athletes' quality of life.

RESUMO

Objectives: To validate the items of the Emotional Impact Questionnaire coronavirus disease-2019 (COVID-19) related to risk perception, estimating its degree, among healthcare workers in the first wave of COVID-19 pandemic, identifying possible associated factors.Methods: cross-sectional study in 1872 healthcare workers of Brazil. The population was characterized by sociodemographic and occupational information, knowledge about COVID-19, quality of information received, risk perception and preventive measures about the disease, and sense of coherence. Results: Being divorced, having a chronic disease, spending more than 1 h per day getting informed about COVID-19, and always or almost always wearing a mask regardless of symptoms, as well as self-perception of health were associated with high-risk perception. An inverse association was found between risk perception, sense of coherence and not knowing if one has had occasional contact with confirmed COVID-19 cases. Conclusion: Risk perception is influenced by emotions, experiences, and knowledge. Sense of coherence and resilience have a role in reducing risk perception. Understanding risk perception is crucial for developing effective strategies to mitigate the impact of the COVID-19 pandemic and other similar scenarios.

RESUMO

Suicide is a major public health problem worldwide with far-reaching effects on families, communities, and societies. Influencing factors range from macro-level interventions like alcohol control policies and suicide prevention programs to individual contributors such as alcohol abuse and domestic violence. This study aimed to examine the relationship between Chile's suicide rate changes from 2002 to 2015 and the Alcohol Act of 2004, a national suicide prevention program implemented in 2007, alcohol abuse, and domestic violence. Assembling a unique longitudinal dataset from Chilean public institutions, the study employed an instrumental variable time-series cross-regional design. Results indicated that the Alcohol Act was not associated with suicide rates, domestic violence exhibited a significant association with increased suicide rates, and the national suicide prevention program was linked to reductions in suicide rates, especially among males. These findings align with research from neighbouring countries, showcasing the efficacy of suicide prevention programs in decreasing suicide rates in Chile. Results highlight the importance of integrating protocols to early-detect domestic violence in suicide prevention programs, as well as the need to further improving alcohol control policies to complement suicide prevention programs.

RESUMO

INTRODUCTION: Living guidelines provide reliable, ongoing evidence surveillance and regularly updated recommendations for healthcare decision-making. As a relatively new concept, most of the initial application of living approaches has been undertaken in high-income countries. However, in this scoping review, we looked at what is currently known about how living guidelines were developed, used and applied in low-income and middle-income countries. METHODS: Searches for published literature were conducted in Medline, Global Health, Cochrane Library and Embase. Grey literature was identified using Google Scholar and the WHO website. In addition, the reference lists of included studies were checked for missing studies. Studies were included if they described or reflected on the development, application or utility of living guideline approaches for low-income and middle-income countries. RESULTS: After a full-text review, 21 studies were included in the review, reporting on the development and application of living recommendations in low-income and middle-income countries. Most studies reported living guideline activities conducted by the WHO (15, 71.4%), followed by China (4, 19%), Chile (1, 4.8%) and Lebanon (1, 4.8%). All studies based on WHO reports relate to living COVID-19 management guidelines. CONCLUSIONS: Most of the studies in this review were WHO-reported studies focusing solely on COVID-19 disease treatment living guidelines. However, there was no clear explanation of how living guidelines were used nor information on the prospects for and obstacles to the implementation of living guidelines in low-income and middle-income countries.
