Refractive Errors of School Children from Economically Disadvantaged Areas in Northwest México.

Background: Refractive errors, including myopia, hyperopia, and astigmatism, are the leading causes of visual impairment in school-aged children and can significantly impact their academic performance and quality of life. This study aimed to assess the prevalence of refractive errors among school children from economically disadvantaged areas in Northwest México, using a consistent methodology to facilitate comparison with global data. Methods: We adopted the Refractive Error Study in Children (RESC) protocol by the World Health Organization to examine the prevalence of myopia, hyperopia, and astigmatism. The study comprised a systematic sampling of children aged 6 to 18 years from diverse schools in Northwest México. Trained optometrists conducted visual acuity testing and autorefraction, while ophthalmologists performed cycloplegic refraction to ensure accuracy. Results: The study found a myopia (SE ≤-1.50 D at least one eye) prevalence of 14.55% (95% CI: 13.27-15.91), with a higher incidence in females (6.92%) compared to males (6.00%) in at least one eye. Hyperopia (SE ≥ +1.00 D at least one eye) was less common, at 3.23% (95% CI: 2.61-3.95), with a slightly higher occurrence in males in at least one eye. Astigmatism (Cylinder ≥ 0.75 D at least one eye) was present in 18.63% (95% CI: 17.21-20.12) of the students in at least one eye, with no significant difference between genders. These findings are consistent with other studies in regions such as Puerto Rico and Iran, indicating widespread refractive error issues among schoolchildren. Conclusions: The high prevalence of refractive errors, particularly myopia and astigmatism, highlights the critical need for regular vision screenings in schools and the implementation of public health interventions to provide corrective eyewear. Our study confirms the importance of utilizing standardized methodologies like the RESC protocol to compare refractive error prevalence across different geographical and socio-economic contexts, thereby informing global public health strategies.

Barriers to early diagnosis and management of oral cancer in Latin America and the Caribbean.

OBJECTIVE: This study aimed to explore perceived barriers to early diagnosis and management of oral cancer, as well as potential pathways for improvement in Latin America and the Caribbean (LAC). METHODS: This cross-sectional study used a self-administered online questionnaire created via the Research Electronic Data Capture platform. The survey was distributed to health professionals trained in Oral Medicine, Oral Pathology, Oral and Maxillofacial Surgery, and Dentists with clinical and academic expertise in oral potentially malignant disorder (OPMD) and oral cancer. Data obtained were systematically organized and analyzed descriptively using Microsoft Excel. RESULTS: Twenty-three professionals from 21 LAC countries participated. Major barriers included the limited implementation of OPMD and oral cancer control plans (17.4%), low compulsory reporting for OPMD (8.7%) and oral cancer (34.8%), unclear referral pathways for OPMD (34.8%) and oral cancer (43.5%), and a shortage of trained professionals (8.7%). Participants endorsed the utility of online education (100%) and telemedicine (91.3%). CONCLUSION: The survey highlights major perceived barriers to early diagnosis and management of OPMD and oral cancer in LAC, as well as potential avenues for improvement.

National sex- and age-specific burden of blindness and vision impairment by cause in Mexico in 2019: a secondary analysis of the Global Burden of Disease Study 2019.

Background: Reliable national estimations for blindness and vision impairment are fundamental to assessing their burden and developing public health policies. However, no comprehensive analysis is available for Mexico. Therefore, in this observational study we describe the national burden of blindness and vision loss by cause and severity during 2019. Methods: Using public data from the Global Burden of Disease (GBD) study 2019, we present national prevalence and years lived with disability (YLDs) counts and crude and age-standardized rates (per 100,000 people) of total, severity- and cause-specific blindness and vision impairment with 95% uncertainty intervals (UIs) by sex and age group. Findings: In Mexico, the burden of blindness and vision impairment was estimated at 11.01 million (95% UI, 9.25-13.11) prevalent cases and 384.96 thousand (259.57-544.24) YLDs during 2019. Uncorrected presbyopia caused the highest burden (6.06 million cases, 4.36-8.08), whereas severe vision loss and blindness affected 619.40 thousand (539.40-717.73) and 513.84 thousand (450.59-570.98) people, respectively. Near vision loss and refraction disorders caused 78.7% of the cases, whereas neonatal disorders and age-related macular degeneration were among the least frequent. Refraction disorders were the main cause of moderate and severe vision loss (61.44 and 35.43%), and cataracts were the second most frequent cause of blindness (26.73%). Females suffered an overall higher burden of blindness and vision impairment (54.99% and 52.85% of the total cases and YLDs), and people >50 years of age suffered the highest burden, with people between 70 and 74 years being the most affected. Interpretation: Vision loss represents a public health problem in Mexico, with women and older people being the most affected. Although the causes of vision loss contribute differentially to the severity of visual impairment, most of the impairment is avoidable. Consequently, a concerted effort at different levels is needed to alleviate this burden. Funding: This study received no funding.

Doxorubicin Activity Is Modulated by Traditional Herbal Extracts in a 2D and 3D Multicellular Sphere Model of Leukemia.

The modulation of the tumor microenvironment by natural products may play a significant role in the response of tumor cells to chemotherapy. In this study, we evaluated the effect of extracts derived from P2Et (Caesalpinia spinosa) and Anamú-SC (Petiveria alliacea) plants, previously studied by our group, on the viability and ROS levels in the K562 cell line (Pgp- and Pgp+), endothelial cells (ECs, Eahy.926 cell line) and mesenchymal stem cells (MSC) cultured in 2D and 3D. The results show that: (a) the two botanical extracts are selective on tumor cells compared to doxorubicin (DX), (b) cytotoxicity is independent of the modulation of intracellular ROS for plant extracts, unlike DX, (c) the interaction with DX can be influenced by chemical complexity and the expression of Pgp, (d) the 3D culture shows a greater sensitivity of the tumor cells to chemotherapy, in co-treatment with the extracts. In conclusion, the effect of the extracts on the viability of leukemia cells was modified in multicellular spheroids with MSC and EC, suggesting that the in vitro evaluation of these interactions can contribute to the comprehension of the pharmacodynamics of the botanical drugs.

A Novel Framework for Generating Personalized Network Datasets for NIDS Based on Traffic Aggregation.

In this paper, we addressed the problem of dataset scarcity for the task of network intrusion detection. Our main contribution was to develop a framework that provides a complete process for generating network traffic datasets based on the aggregation of real network traces. In addition, we proposed a set of tools for attribute extraction and labeling of traffic sessions. A new dataset with botnet network traffic was generated by the framework to assess our proposed method with machine learning algorithms suitable for unbalanced data. The performance of the classifiers was evaluated in terms of macro-averages of F1-score (0.97) and the Matthews Correlation Coefficient (0.94), showing a good overall performance average.

Introduction Hip fracture is a public health problem due to its association with high mortality rates at one year, functional decline and worsening of quality of life. A multidisciplinary approach improves outcomes for elderly patients with fragility fracture. Objective To carry out a narrative review to evaluate the evidence of orthogeriatric units as a strategy to reduce adverse outcomes in older adults with fragility hip fractures. Material and Methods A literature search was carried out in the following databases: PubMed, Cochrane and Scielo, with the terms: "hip fracture" or "fragility fracture" AND "multidisciplinary team" or "Geriatric co management" or AND "orthogeriatric" or "ortho-geriatric". Results Care by orthogeriatrics reduces pre-operative surgical time, postoperative complications and hospital stay. Interdisciplinary assessment has been shown to be effective in reducing functional decline, in-hospital mortality, 30-day mortality, and the risk of institutionalization compared to other models of care. These factors impact on the optimization of resources, reducing health costs. Conclusion Orthogeriatric services are the ideal model to treat fragility fractures in older adults. In Colombia, more orthogeriatric units should be implemented to improve in-hospital care, create follow-up and rehabilitation programs.

Refractive Error of Students (15- to 18-year-olds) in Northwest Mexico.

SIGNIFICANCE: We assessed the prevalence of refractive error in a sample of children of Northern Mexico using the Refractive Error Study in Children protocol of the World Health Organization, which allows for the comparison with other global studies. PURPOSE: Uncorrected refractive error is the main cause of visual impairment in children. The purpose of this study was to assess the refractive error and visual dysfunctions of students (15 to 18 years old) in the upper-middle school system of Sinaloa, Mexico. METHODS: A total of 3468 students in Sinaloa's high school system participated in the study from 2017 to 2019. Optometrists and student clinicians from the Optometry Program of the Autonomous University of Sinaloa conducted the testing. Tests included visual acuities and static retinoscopy. We did not use a cycloplegic agent. RESULTS: The results showed a high prevalence of uncorrected refractive errors. Myopia, defined as a refractive error ≤-0.50 D, had a prevalence of 36.11% (95% confidence interval, 33.47 to 38.83%); hyperopia, defined as a refractive error ≥+2.00 D, had a prevalence of 1.49% (95% confidence interval, 0.09 to 2.33%); and astigmatism, defined as a refractive error with a cylinder ≥0.75 D, had a prevalence of 29.17% (95% confidence interval, 26.60 to 31.76%). We found a significant effect of sex on visual acuity. CONCLUSIONS: Our results are consistent with a high prevalence of myopia reported in adolescents worldwide and in Mexico's northern regions. The results suggest that students attending high school and entering universities should be required to have an optometric eye examination. Additional studies are needed to investigate the prevalence of refractive errors in children in Mexico.

TRPM8 Channel Promotes the Osteogenic Differentiation in Human Bone Marrow Mesenchymal Stem Cells.

Various families of ion channels have been characterized in mesenchymal stem cells (MSCs), including some members of transient receptor potential (TRP) channels family. TRP channels are involved in critical cellular processes as differentiation and cell proliferation. Here, we analyzed the expression of TRPM8 channel in human bone marrow MSCs (hBM-MSCs), and its relation with osteogenic differentiation. Patch-clamp recordings showed that hBM-MSCs expressed outwardly rectifying currents which were increased by exposure to 500 µM menthol and were partially inhibited by 10 µM of BCTC, a TRPM8 channels antagonist. Additionally, we have found the expression of TRPM8 by RT-PCR and western blot. We also explored the TRPM8 localization in hBM-MSCs by immunofluorescence using confocal microscopy. Remarkably, hBM-MSCs treatment with 100 µM of menthol or 10 µM of icilin, TRPM8 agonists, increases osteogenic differentiation. Conversely, 20 µM of BCTC, induced a decrease of osteogenic differentiation. These results suggest that TRPM8 channels are functionally active in hBM-MSCs and have a role in cell differentiation.

Comportamiento de reingreso a 30 días en un centro de reemplazos articulares. Estudio de cohorte longitudinal / 30 days re-admission in an articular Joint Arthroplasty center. A cohort Study

Introducción Los reemplazos articulares son calificados como procedimientos seguros y exitosos para el tratamiento de la osteoartrosis severa de cadera y rodilla alrededor del mundo. Las tasas de reingreso en los primeros 30 días y las complicaciones se han descrito como una medida para evaluar estándares de calidad. En Colombia no se conoce el comportamiento de éstos estándares. Este estudio pretende aportar información de un centro especializado en reemplazos articulares en Bogotá DC, Colombia, Suramérica. Materiales & Métodos Se realizó un estudio observacional prospectivo de una cohorte de 1.126 pacientes con 626 reemplazos totales de cadera (RTC) y 500 de rodilla (RTR), operados entre los años 2011-2015 en el Hospital Universitario San Ignacio de Bogotá DC, Colombia. Se reportan las tasas de reingreso a 30 días y las complicaciones. Se analiza mediante un modelo de regresión las asociaciones entre variables sociodemográficas y clínicas con el reingreso y las complicaciones. Resultados El 71% de los pacientes fueron mujeres, el promedio de edad de 63 años en los hombres y 65 años en mujeres. La estancia hospitalaria promedio fue de 3,5 días (DE:0,81-6,29). La tasa de reingreso a 30 días por cualquier causa fue 10,8% y la tasa de complicaciones asociadas al procedimiento fue 5,8%, se requirió reintervención quirúrgica en 1,5% de los pacientes. Se encontró asociación estadísticamente significativa entre el índice de Charlson mayor a 2 (OR=2,33[IC95% 1,3-4,18], p=0.004) y el reingreso a 30 días. La principal complicación en RTC fue luxación (1,4%) y en RTR infección de sitio quirúrgico (4%). Se encontró una asociación significativa entre complicaciones a 30 días con los días de hospitalización (OR=1,17[IC95% 1,09-1,25], p=0,00); y con el cirujano 4 en RTR (OR=2,28[IC95% 1,29-4,01], p=0,04); las demás variables no mostraron diferencias significativas. No se aprecian grandes diferencias con lo reportado en la literatura, asociación con estancia hospitalaria y experiencia del cirujano. Discusión La experiencia del cirujano y la aplicación de guías clínicas que optimicen los procesos intrahospitalarios y regulen los días de estancia hospitalaria, se relacionan con un mejor desenlace en la evolución de los pacientes en cuanto al número de complicaciones y reingresos a 30 días.

Background Joint replacements are always defined as safe and successful procedures for the treatment of severe osteoarthritis of the hip and knee around the world. Rates of readmission within initial post surgical 30 days and complications are described as a measure to assess quality standards. In Colombia the behavior of the standards are mainly unknown. Aim of study is to provide information from a specialized in joint replacements center in Colombia. Methods A prospective observational study was carried out on a cohort of 1,126 patients with 626 total hip replacements (THR) and 500 knee replacements (TKR), who underwent surgery between 2011-2015 at a University Hospital in Bogotá, Colombia. 30-day readmission rates and complications were reported. The associations between sociodemographic and clinical variables with readmission and complications were analyzed using a regression model. Results 71% of the patients were women, the average age was 63 years for men and 65 years for women. The mean hospital stay was 3.5 days (SD: 0.81-6.29). The 30-day readmission rate for any cause was 10.8% and the rate of complications associated with the procedure was 5.8%. Additional surgical procedures were required in 1.5% of the patients. A statistically significant association was found between the Charlson index greater than 2 (OR=2.33 [95% CI 1.3-4.18], p=0.004) and readmission at 30 days. The main complication in THR was dislocation (1.4%) and surgical site infection (4%) in TKR. A significant association was found between complications at 30 days and days of hospitalization (OR=1.17 [95% CI 1.09-1.25], p=0.00); and with surgeon 4 in TKR (OR=2.28 [95% CI 1.29-4.01], p=0.04); the other variables did not show significant differences. No differences were found with what is reported in the literature, association with hospital stay and experience of the surgeon. Discussion The surgeon's experience and the application of clinical guidelines that optimize in-hospital processes and regulate the days of hospital stay are related to a better outcome in the evolution of patients in terms of the number of complications and readmissions after 30 days.

Generation of Organotypic Multicellular Spheres by Magnetic Levitation: Model for the Study of Human Hematopoietic Stem Cells Microenvironment.

BACKGROUND AND OBJECTIVE: The characteristics of human hematopoietic stem cells are conditioned by the microenvironment of the bone marrow, where they interact with other cell populations, such as mesenchymal stem cells and endothelial cells; however, the study of this microenvironment is complex. The objective of this work was to develop a 3D culture system by magnetic levitation that imitates the microenvironment of human HSC. METHODS AND RESULTS: Human bone marrow-mesenchymal stem cells, umbilical cord blood-hematopoietic stem cells and a non-tumoral endothelial cell line (CC2811, LonzaⓇ) were used to develop organotypic multicellular spheres by the magnetic levitation method. We obtained viable structures with an average sphericity index greater than 0.6, an average volume of 0.5 mm3 and a percentage of aggregation greater than 70%. Histological studies of the organotypic multicellular spheres used hematoxylin and eosin stains, and an evaluation of vimentin expression by means of immunohistochemistry demonstrated an organized internal structure without picnotic cells and a high expression of vimentin. The functional capacity of human hematopoietic stem cells after organotypic multicellular spheres culture was evaluated by multipotency tests, and it was demonstrated that 3D structures without exogenous Flt3L are autonomous in the maintenance of multipotency of human hematopoietic stem cells. CONCLUSIONS: We developed organotypic multicellular spheres from normal human cells that mimic the microenvironment of the human hematopoietic stem cells. These structures are the prototype for the development of complex organoids that allow the further study of the biology of normal human stem cells and their potential in regenerative medicine.

Relación entre enfermedades periodontales y salud sistémica en la vejez / The relationship between periodontal disease and systemic health in the elderly

Se denomina Medicina Periodontal a la rama de la Odontología que busca las posibles asociaciones entre las enfermedades periodontales y enfermedades sistémicas, y su plausibilidad biológica. Esta relación se puede explicar por el paso directo de bacterias y/o mediadores inflamatorios a la sangre desde el tejido periodontal, pudiendo acceder y colonizar sitios específicos lejanos en el cuerpo, o por la propagación transtraqueal de patógenos periodontales. Si bien en la actualidad se han estudiado hasta 57 condiciones sistémicas relacionadas con las enfermedades orales y periodontales, se ha podido identificar asociaciones con Osteoporosis, Diabetes Mellitus, Enfermedad Pulmonar Obstructiva Crónica, Neumonía, Parto Prematuro y Bajo Peso al Nacer, Enfermedades Cardiovasculares, Artritis Reumatoide, Obesidad, Alteraciones Cognitivas, Cáncer, Síndrome Metabólico, Enfermedades Neurodegenerativas, Enfermedad Renal Crónica, entre otras. La presente revisión busca dar a conocer evidencia respecto a la relación entre Periodontitis Crónica y condiciones sistémicas prevalentes en los Adultos y Adultas Mayores

The branch of dentistry enquiring into possible associations between periodontal disease and systemic illness and their plausibility is Periodontal Medicine. This relationship may be explained by the direct passage of bacteria and/or inflammatory mediators from periodontal tissue to the blood, thus reaching and colonising distant sites in the body, or the transtracheal propagation of periodontal pathogens. 57 systemic conditions related to oral and periodontal disease have been studied and associations with osteoporosis, diabetes mellitus, COPD, pneumonia, prematurity and low birth weight, cardiovascular disease, rheumatoid arthritis, obesity, cognitive alterations, cancer, metabolic syndrome, neurodegenerative diseases and chronic kidney disease, amongst others have been identified. This review aims to bring to light evidence relating to the relationship between chronic periodontitis and systemic conditions prevalent in adults and the elderly.

Mucocele del seno maxilar: Reporte de caso

Los mucoceles maxilares son lesiones que tienen un crecimiento gradual. Son de tipo quístico y contienen secreciones mucoides que causan erosiones a estructuras vecinas al aumentar su tamaño. Aunque la mayoría de las veces son completamente asintomáticas, pueden presentarse síntomas como dolor facial opaco, inflamación en la mejilla, y obstrucción nasal. Estos síntomas y cambios en la simetría facial se hacen presentes cuando hay erosión significativa de estructuras anatómicas circundantes. EL seno maxilar es el sitio menos frecuente donde se forman , y su diagnóstico se realiza con la ayuda de una tomografía computadorizada. La remoción quirúrgica completa es el mejor tratamiento indicado.

The maxillary sinus mucoceles are lesions which grow gradually. They are cyst like lesions which have mucoid secretions that cause erosion to neighboring structures as they increase in size. Although they are often asymptomatic, they can be present as dull orofacial pain, inflammation on the cheek and nasal obstruction. These symptoms and changes in facial symmetry are present when there is significant erosion to surrounding anatomic structures. The Maxillary Sinus is the less frequent site where these lesions will form, and the diagnosis is done with the assistance of Computerized Tomography. Complete surgical removal is the best treatment option.

Relación entre la concentración de ácido láctico en saliva y caries dental en escolares de 6 a 12 años / Relationship between the concentration of lactic acid in saliva and dental caries in schoolchildren of 6 to 12 years old

Objetivo. Determinar la relación que hay entre la concentración de ácido láctico en saliva y caries dental en escolares de 6 a 12 años. Material y métodos. Estudio correlacional, diseño transversal. La muestra fue de 83 escolares entre 6 y 12 años de edad. Se realizó un examen intraoral cuyos datos se registraron en el odontograma. Se colectó la saliva de cada escolar (3ml) y se determinó los índices del CPOD y ceod, para relacionarlos con los datos de las concentraciones del ácido láctico de la saliva, obtenidas a través del método calorimétrico utilizando el reactivo parahidroxidifenilo. Resultados. El promedio correspondiente a la concentración de ácido láctico en saliva fue de 1,71mg/dl, y el de las piezas con caries dental fue de 3,39. El índice del CPOD fue de 1,02, y del ceod fue de 2,36. Del total de escolares, 44 tuvieron ácido láctico bajo y de cuatro a más dientes con caries dental, 19 escolares tuvieron ácido láctico medio y presentaron de cuatro a más caries, 20 escolares con ácido láctico alto, tienen de cuatro a más caries. La correlación entre el ácido láctico y el nº de piezas dentales con caries es estadísticamente significativa según Pearson con un nivel de confianza del 95%. Conclusiones.

Objective. To determine the relationship between the concentration of lactic acid in saliva and dental caries in schoolchildren of 6 to 12 year old. Material andmethods. Correlation study, cross design. The sample consisted of 83 schoolchildren of 6 to 12 years old. I made the intraoral examination which data were recorded in the odontogram. Saliva was collected from each schoolchild (3ml). CPOD and ceod index were determined to relate them with the data from lacticacid concentrations of saliva, obtained by calorimetric method using the parahidroxidifenilo reagent. Results. The average for the lactic acid concentration insaliva was 1.71mg/dl, and those of of the pieces of dental caries were 3.39. The CPOD index is 1.02, and ceod is 2.36. 44 schoolchildren with low lactic acid, they do not have four or more cavities, 19 schoolchildren with medium lactic acid, they have four or more cavities, 20 schoolchildren with high lactic acid, have fouror more cavities. The correlation between lactic acid and the number of teeth with caries was statistically significant for Pearson with a confidence level of 95%.Conclusions. This technique could be used in the diagnostic evaluation of individual risk. There is a perfect positive linear correlation, as both variables have adirect relationship.
