Abstract: OBJECTIVE: To study the severity of symptoms and estimate the prevalence of oral mucosal lesions in a non-referral adult Swedish population, as registered by general dental practitioners. This study also aims to evaluate the possibility of dental practitioners collecting large quantities of reliable and accurate clinical data on oral mucosal lesions. STUDY DESIGN: Data from 6,448 adult Swedish patients were collected by general dental practitioners using a standardized registration method. A correlation analysis between a group with oral mucosal lesions and a control group, with no oral mucosal lesions, was performed for various parameters such as symptoms from the oral mucosa, systemic diseases, medication, allergy history, tobacco habits and the patient's own assessment of their general health. In addition, clinical photos were taken of all oral mucosal lesions in order to determine the degree of agreement between the diagnoses made by general dental practitioners and those made by oral medicine specialists. RESULTS: A total of 950 patients (14.7%) presented with some type of oral mucosal lesion and of these, 141 patients (14.8%) reported subjective symptoms. On a visual analogue scale, 43 patients (4.5%) scored their symptoms <30, 65 patients (6.8%) scored their symptoms ?30, and 28 patients (2.6%) scored their symptoms ?60. The most debilitating condition was aphthous stomatitis and the most common oral mucosal lesion was snuff dipper's lesion (4.8%), followed by lichenoid lesions (2.4%) and geographic tongue (2.2%). There was agreement between the oral medicine specialists and the general practitioners over the diagnosis of oral mucosal lesions on the basis of a clinical photograph in 85% of the cases (n=803). CONCLUSIONS: Nearly 15% of the patients with oral mucosal lesions reported symptoms. General practitioners could contribute significantly to the collection of large quantities of reliable and accurate clinical data, although there is a risk that the prevalence of oral mucosal lesions may be underestimated." Resumen: OBJETIVO: Estudiar la severidad de los síntomas y estimar la prevalencia de lesiones de la mucosa oral en una población de Suecia no referida, y registrada por odontólogos generales. Este estudio también tiene como objetivo evaluar la posibilidad de que odontólogos generales recolecten de forma confiable y precisa grandes cantidades de datos clínicos sobre lesiones de la mucosa oral. DISEÑO DEL ESTUDIO: Datos de 6.448 pacientes adultos suecos fueron recolectados por odontólogos generales usando un método estandarizado de registro. Un análisis de correlación entre un grupo de pacientes con lesiones de la mucosa oral y un grupo control, sin lesiones de la mucosa oral, fue realizado para varios parámetros como síntomas en la mucosa oral, enfermedades sistémicas, medicamentos, alergias, tabaquismo, y la percepción del propio paciente sobre su estado de salud. Además, se tomaron fotos clínicas de todas las lesiones de la mucosa oral con el fin de determinar el grado de concordancia entre los diagnósticos realizados por los odontólogos generales y los especialistas en medicina oral. RESULTADOS: Un total de 950 pacientes (14.7%) presentó algún tipo de lesión de la mucosa oral, y de estos, 141 pacientes (14.8%) reportaron síntomas subjetivos. En una escala analógica visual, 43 pacientes (4.5%) calificaron sus síntomas <30, 65 pacientes (6.8%) calificaron sus síntomas ≥30, y 28 pacientes (2.6%) calificaron sus síntomas ≥60. La condición más debilitante fue la stomatitis aftosa y la lesión más común fue la lesión causada por el tabaco húmedo (4.8%), seguida por reacciones liquenoides (2.4%) y lengua geográfica (2.2%). Basado en las fotografías clínicas, hubo una concordancia en el diagnóstico de lesiones de la mucosa oral entre los especialistas en medicina oral y los odontólogos generales en el 85% de los casos (n=803). CONCLUSION: Aproximadamente el 15% de los pacientes con lesiones de la mucosa oral reportaron síntomas. Los odontólogos generales pueden contribuir significativamente en la recolección confiable y precisa de grandes cantidades de datos clínicos, aunque existe un riego de que la prevalencia de lesiones de la mucosa oral pueda ser subestimada."

Through the financial support from the Open Society Foundations, Dejusticia developed a diagnostic research from eight countries, Argentina, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Panama and Uruguay, regarding the access to palliative care, the institutional development and the guidelines, and the existing barriers of access to opioid medications – used for pain relief. This document is aimed at medical personnel, civil society organizations, policy makers, and any¬one interested in addressing the issue of palliative care from a human rights perspective. Although for years palliative care was confined to a strictly medical analysis, in recent times the international community and United Nations bodies have recognized palliative care as a human rights issue. This document seeks to demonstrate the many linkages between palliative care and human rights in terms of both the conception and the protection of palliative care. We hope this report serves as a useful tool for the medical community, patients, and patients’ fam¬ilies throughout the American continent who seek legal and human rights arguments to facilitate access to more humane end-of-life care, as well as for litigants and human rights activists who wish to protect and guarantee a life without pain for patients, including during their last days of life.

OBJECTIVE: Conditional cash transfer (CCT) programmes provide income to low-income families in return for fulfilling specific behavioural conditions. CCT have been shown to improve child health, but there are few systematic studies of their impact on multiple determinants of child health. We examined the impact of a CCT programme in Colombia on: (i) use of preventive health services; (ii) food consumption and dietary diversity; (iii) mother's knowledge, attitudes and practices about caregiving practices; (iv) maternal employment; and (v) women's empowerment. DESIGN: Secondary analysis of the quasi-experimental evaluation of the Familias en Accion programme. Children and families were assessed in 2002, 2003 and 2005-06. We applied a difference-in-differences approach using logistic or linear regression, separately examining effects for urban and rural areas. SETTING: Colombia. SUBJECTS: Children (n 1450) and their families in thirty-one treatment municipalities were compared with children (n 1851) from sixty-five matched control municipalities. RESULTS: Familias en Accion was associated with a significant increase in the probability of using preventive care services (OR=1·85, 95 % CI 1·03, 3·30) and growth and development check-ups (?=1·36, 95 % CI 0·76, 1·95). It had also a positive impact on dietary diversity and food consumption. No effect was observed on maternal employment, women's empowerment, and knowledge, attitudes and practices about caregiving practices. Overall, Familias en Accion's impact was more marked in rural areas. CONCLUSION: CCT in Colombia increase contact with preventive care services and improve dietary diversity, but they are less effective in influencing mother's employment decisions, empowerment and knowledge of caregiving practices.

Abstract: Antibiotic resistance is driven by selection, but the degree to which a bacterial strain’s evolutionary history shapes the mechanism and strength of resistance remains an open question. Here, we reconstruct the genetic and evolutionary mechanisms of carbapenem resistance in a clinical isolate of Klebsiella quasipneumoniae. A combination of short- and long-read sequencing, machine learning, and genetic and enzymatic analyses established that this carbapenem-resistant strain carries no carbapenemase-encoding genes. Genetic reconstruction of the resistance phenotype confirmed that two distinct genetic loci are necessary in order for the strain to acquire carbapenem resistance. Experimental evolution of the carbapenem-resistant strains in growth conditions without the antibiotic revealed that both loci confer a significant cost and are readily lost by de novo mutations resulting in the rapid evolution of a carbapenem-sensitive phenotype. To explain how carbapenem resistance evolves via multiple, low-fitness single-locus intermediates, we hypothesised that one of these loci had previously conferred adaptation to another antibiotic. Fitness assays in a range of drug concentrations show how selection in the antibiotic ceftazidime can select for one gene (blaDHA-1) potentiating the evolution of carbapenem resistance by a single mutation in a second gene (ompK36). These results show how a patient’s treatment history might shape the evolution of antibiotic resistance and could explain the genetic basis of carbapenem-resistance found in many enteric-pathogens.

Kinesiology tape is commonly applied to enhance muscle functioning. The targeted improvement could be influenced by the neuromuscular stimulation acquired within the muscle and modulated by the mechanoreceptor after its application. The importance of the muscular facilitation effect that K-TAPE may produce within the muscle lies on the direct impact of this property on athletes’ performance, health promotion, injury- prevention and rehabilitations programs. This study seeks to investigate if the application of K-TAPE, from origin to insertion of the RF, significantly increase the motor unit firing within the muscle, after performing a MVC. More precisely, this study examines whether this application leads to a better muscle functioning or conversely, no significant differences on the electrical stimulation within the rectus femuris muscle when using K-TAPE after MVC. Based on an EMG experimental study and using pre-test/post-test designs, twenty healthy subjects were randomly allocated into experiment and control groups. Using regression analysis to compare pre-test and post-test EMG outputs, findings of this study confirm a significant improvement on the neuromuscular facilitation of the rectus femuris of 7% on average. This result is statistically significant at 5% confidence level. Additional tests show that the difference can be as high as 25% after the application of the K-tape. Further analysis on the control group could not reject the theory proved on the experiment group. The contribution made in this study proves that Kinesiology tape can be used to enhance the muscular functioning.

Abstract: Background: Seasonal Influenza is considered to be a cyclic and ordered sequence of values, influenced by external factors that can be predicted and used to detect disease outbreaks and monitoring. In machine learning, the key challenges that limit these analyses are in model explainability and limitations associated with ecological bias. Aim: Determine the best environmental variable selection method to predict Seasonal Influenza in Norway, using an environmental medicine approach combined with machine learning techniques. Methods: This is a quasi-experimental study that compares three approaches (non-variable selection, isolate component, and multipollutant mixture), represented in five methods (univariable, bivariable, multivariable AME, multivariable PCA, multivariable LDA). Per method, the best co-variable combination will be performed, following the internal rules of each method. The best covariable combination is the result of three components: variable selection, validation data set and lag. The first one involves 13 environmental variables (temperature, relative humidity, specific humidity, air pressure, wind speed, precipitation, CO, NO, NO2, O3, PM10, PM2,5 and SO2); second one compares a test dataset compiled from the data from 2019, last year (2018) and a synthetic environmental (avg. 2013-2018) data set in the validation process; and the third one compares a combination of lag from 0 to 12. All the predictions are made using ARIMA algorithm. The evaluation is given in terms of MAE, MSE, RMSE, OR. The training set is from 2 Jun 2013 (week 22/2013) to 28 May 2018 (week 21/2018), and test set is from (week 22/2018) to (week 21/2019) with a window of predictions of 52 weeks. Results: The increment of dimensionality in the environmental variable selection introduce different noise levels and optimize the prediction. Considerations that impact the explainability, usability, ecological bias and performance will be described. Conclusion: The increment of dimensionality in the variable selection has a better impact on performance than using complex algorithms.

In 2007, Mexico City legalized abortion in the first 12 weeks of pregnancy. By doing so, it became the first and only state in Mexico where abortion on demand is legal. In this paper, I use this natural experiment to estimate the effects of abortion legalization on child and maternal health. I perform Difference-In-Differences estimates using information from all births and deaths occurred between 2002 and 2012. My findings suggest that the change in the abortion legislation in Mexico City reduced the Infant Mortality Rate and the Under 5 Mortality Rate by approximately 2.3 and 2.4 deaths per 1,000 live births, respectively. Moreover, for the Maternal Mortality Rate I find that the estimations range from -5.49 to -6 deaths per 100,000 live births. These results are validated by the use of a more accurate control group generated by the Synthetic Control Method. To the best of my knowledge, this if the first paper that attempts to examine the effects of abortion legalization in Mexico City on child health. En el 2007, Ciudad de México legalizó el aborto en las 12 primeras semanas de gestación. Al hacerlo, se convirtió en el primero y único estado del país en donde el aborto voluntario es legal. En este artículo utilizo este experimento natural para estimar los efectos de la legalización del aborto en la salud materno infantil. Realizo estimaciones de Diferencias en Diferencias utilizando información de todos los nacimientos y muertes ocurridos entre 2002 y 2012. Mis hallazgos sugieren que el cambio en la legislación relativa el aborto en la Ciudad de México redujo la tasa de mortalidad Infantil y la tasa de mortalidad en menores de 5 años en aproximadamente 2.3 y 2.4 muertes por cada 1.000 nacidos vivos, respectivamente. Además, para la tasa de mortalidad materna, encuentro que las estimaciones oscilan entre -5,49 y -6 muertes por 100.000 nacidos vivos. Estos resultados se validan mediante el uso de un grupo de control más preciso, utilizando la metodología de control sintético. Según mi conocimiento, este es el primer artículo que intenta examinar los efectos de la legalización del aborto en la Ciudad de México sobre la salud infantil.

Abstract: At the present time, climate change and antimicrobial resistance are considered as the most critical threats, affecting human, animal, plant, and environmental health. Although these terms may initially appear different, they are interconnected and share similarities in their causes (human interventions and natural cycles), health, and societal consequences. Climate change is associated through direct and indirect pathways with an increase in infectious diseases. Nonetheless, the association between global warming and antimicrobial resistance requires a comprehensive summary of evidence exploring it. Methods: A literature review was conducted to identify and describe the association between climate change and the rapid emergence and spread of antimicrobial resistance. The search was conducted in the following databases: PubMed, Web of Science, Scopus, Embase, Epistemonikos, and Google Scholar. The search period was restricted to articles published from January 2010 to June 2021. Additionally, a snowballing approach was conducted to identify any additional papers. Data extraction included study location, weather factors, environmental elements, antibiotics, and bacteria analysed, as well as the results. Results: 29 articles were included (ten literature or systematic reviews, eight experimental, six ecological, four observational, and one quasi-experimental). In terms of location, all the studies were conducted in countries between 35° and 75° north latitude. The results suggested some evidence of the effects of climate change (alterations in temperature, precipitation, and humidity) on the emergence and rapid spread of antimicrobial resistance in different environments (water, soil, cryosphere, and air). Temperature was described as a main effect of climate change that had effects on antibiotic resistance (increasing bacteria growth, altering metabolism, inducing crossprotection, and facilitating horizontal gene transfer between bacteria). Additionally, results also described the association between altered rain patterns and humidity and antimicrobial resistance, through the runoff of antibiotic molecules or the transport of antibiotic resistance mechanisms to other areas. Conclusions: This literature review has underscored the association between climate change and antimicrobial resistance. According to the results shown in the selected studies, the alterations in weather factors resulting from climate change have varying effects on the emergence and spread of antibiotic resistance. However, further research is imperative to decipher the complex interactions between other environmental processes, pollutants, patterns of antibiotic consumption, wastewater, animal migration, and regions below the latitudes covered in this literature review.

Abstract: Quantitative analysis of ventricular cerebrospinal fluid (vCSF) proteins following acute brain injury (ABI) may help identify pathophysiological pathways and potential biomarkers that can predict unfavorable outcome. In this prospective proteomic analysis study, consecutive patients with severe ABI expected to require intraventricular catheterization for intracranial pressure (ICP) monitoring for at least 5 days and patients without ABI admitted for elective clipping of an unruptured cerebral aneurysm were included. vCSF samples were collected within the first 24 h after ABI and ventriculostomy insertion and then every 24 h for 5 days. Data-independent acquisition and sequential window acquisition of all theoretical spectra (SWATH) mass spectrometry were used to compare differences in protein expression in patients with ABI and patients without ABI and in patients with traumatic and nontraumatic ABI. We included 50 patients with ABI (SAH n = 23, TBI n = 15, intracranial hemorrhage n = 6, ischemic stroke n = 3, others n = 3) and 12 patients without ABI. There were significant differences in the expression of 255 proteins between patients with and without ABI (p < 0.01). There were intraday and interday differences in expression of seven proteins related to increased inflammation, apoptosis, oxidative stress, and cellular response to hypoxia and injury. Among these, glial fibrillary acidic protein expression was higher in patients with ABI with severe intracranial hypertension (ICH) (ICP ? 30 mm Hg) or death compared to those without (log 2 fold change: +2.4; p < 0.001), suggesting extensive primary astroglial injury or death. Dysregulated vCSF protein expression after ABI may be associated with an increased risk of severe ICH and death. Resumen: El análisis cuantitativo de las proteínas en el líquido cefalorraquídeo ventricular (vLCR) después de una lesión cerebral aguda (LCA) puede ayudar a identificar vías fisiopatológicas y posibles biomarcadores que pueden predecir un resultado desfavorable. En este estudio prospectivo de análisis proteómico, se incluyeron pacientes consecutivos con LCA grave que se esperaba que necesitaran cateterismo intraventricular cerebral para monitorizar la presión intracraneal (PIC) durante al menos 5 días y pacientes sin LCA ingresados para clipaje electivo de un aneurisma cerebral no roto. Las muestras de vCSF se recolectaron dentro de las primeras 24 h después de la inserción del ITB y la ventriculostomía y luego cada 24 h durante 5 días. Se utilizó la espectrometría de masas de adquisición independiente de datos y adquisición de ventana secuencial de todos los espectros teóricos (SWATH) para comparar las diferencias en la expresión de proteínas en pacientes con LCA y pacientes sin LCA y en pacientes con LCA traumática y no traumática. Se incluyeron 50 pacientes con LCA (HSA n = 23, TCE n = 15, hemorragia intracraneal n = 6, ictus isquémico n = 3, otros n = 3) y 12 pacientes sin LCA. Hubo diferencias significativas en la expresión de 255 proteínas entre pacientes con y sin LCA (p <0,01). Hubo diferencias intradía e interdía en la expresión de siete proteínas relacionadas con el aumento de la inflamación, la apoptosis, el estrés oxidativo y la respuesta celular a la hipoxia y las lesiones. Entre estos, la expresión de la proteína ácida fibrilar glial fue mayor en pacientes con LCA con hipertensión intracraneal (HIC) grave (PIC ? 30 mm Hg) o muerte en comparación con aquellos sin (cambio log 2 veces: + 2,4; p < 0,001), lo que sugiere una extensa Lesión astroglial primaria. La expresión desregulada de las proteínas en el vLCR después de una LCA puede estar asociada con un mayor riesgo de HIC grave y muerte.

Abstract: Background: Allergic rhinitis may affect up to 50% of children. Treatment options include allergen avoidance, pharmacotherapy, immunotherapy and multimodal therapies. Nasal saline douching is well established in the treatment of allergic rhinitis in adults, and has recently gained more acceptability in children as the evidence builds for its effectiveness in this age group. To date, however, there is limited data regarding the acceptability and tolerability of nasal saline douching in children with allergic rhinitis. Methods: A search was conducted using Medline and Embase databases from January 1946 until June 2015 on the use of nasal douching in children aged 4 to 12 with allergic rhinitis. All publications identified that assessed the beneficial effects, acceptability and tolerability were included. The evaluation focused on primary (proportion of patients who adopted nasal douching routinely, symptom and quality of life scores) and secondary outcome measures (effects related to delivered method, dose, technique, and frequency of administration). Results: 35 studies were analyzed. Data varied considerably in terms of saline solutions used, modality of application, participant numbers, study design, follow up and outcomes. Factors that appear to influence the acceptability and tolerability of nasal saline douching are parental and health professionals’ preconceptions, and characteristics of the solution. Overall nasal saline irrigation appears to have a positive impact on quality of life, being accepted and tolerated in the majority of children (78-100%). Conclusions: Nasal saline douching has a significant positive impact on the quality of life in children aged 4 to 12 with allergic rhinitis. Among the principal factors that influence acceptability and tolerability of this therapy are the child´s age, delivery system and method, and tonicity. Encouragement and reinforcement is vital to successful compliance. Saline nasal douching provides an accessible, low cost, low morbidity, easy to use treatment that could be standardized as part of allergic rhinitis management in children. Resumen: Antecedentes: La rinitis alérgica puede afectar hasta el 50% de los niños. Las opciones de tratamiento incluyen evitar el alergeno, la farmacoterapia, la inmunoterapia y las terapias multimodales. La aplicación de la solución salina nasal hace parte del tratamiento de la rinitis alérgica en adultos, y recientemente ha ganado más aceptación en los niños a medida que la evidencia demuestra su eficacia en este grupo etario. Hasta la fecha, sin embargo, hay datos limitados en cuanto a la aceptabilidad y la tolerabilidad de la solución salina nasal en niños con rinitis alérgica. Métodos: Se realizó una búsqueda a través de Medline y EMBASE desde enero de 1946 hasta junio de 2015 sobre el uso de solución salina nasal en niños de 4 a 12 años con rinitis alérgica. Todas las publicaciones identificadas que evaluaron los efectos beneficiosos, la aceptabilidad y la tolerabilidad, fueron incluidas. La evaluación se centró en resultados primarios (proporción de pacientes que adoptaron las duchas nasales de forma rutinaria, los síntomas y la calidad de vida de las puntuaciones) y resultados secundarios (efectos relacionados con el método de entrega, la dosis, la técnica y la frecuencia de administración). Resultados: Se analizaron 35 estudios. Los datos variaron considerablemente en términos de soluciones salinas utilizadas, modalidad de aplicación, el número de participantes, el diseño del estudio, el seguimiento y resultados. Los factores que parecen influir en la aceptabilidad y la tolerabilidad de la solución salina nasal son las ideas preconcebidas de los padres y profesionales de la salud, y las características de la solución. En general, la irrigación salina nasal parece tener un impacto positivo en la calidad de vida, siendo aceptado y tolerado en la mayoría de los niños (78-100%). Conclusiones: La solución salina nasal tiene un impacto significativamente positivo en la calidad de vida en niños de 4 a 12 años con rinitis alérgica. Entre los principales factores que influyen en la aceptabilidad y la tolerabilidad de esta terapia son la edad del niño, el sistema de entrega y su forma, así como la tonicidad de la solución. El estímulo y refuerzo de este hábito como parte de la terapia, es vital para su adherencia. La solución salina nasal proporciona una terapia de bajo costo, accesible, de baja morbilidad, y fácil de usar que podría ser estandarizada como parte del tratamiento de la rinitis alérgica en niños.
