Unveiling the dynamics of sexual crimes in Colombia based on complaints over a decade / Desvelando la dinámica de los delitos sexuales en Colombia a partir de las denuncias de más de una década / Revelando a dinâmica de crimes sexuais na Colômbia, com sede em reclamações ao longo de uma década

The aim of this article was to analyse the dynamics of sexual offense reports in Colombia over the period between 2010 and 2022. For this, a mixed methodology was applied in the following phases: first, the Colombian National Police registry ­which included 286 604 sexual crimes reported in the aforementioned period­ was analysed. Then, a causal loop diagram of System Dynamics was designed to highlight the role of reporting sexual crimes in the Colombian Penal System. The main findings of this article include that 85.73 % of the complaints are mostly associated with women and 68 % of the victims are minors or adolescents of both sexes. It must be noted that Colombian legislation divides these crimes into those that are aggravated by violence and those that are not. It was also found that when the victim was a woman, the crimes occurred in a higher proportion with the aggravating factor of violence. It can also be concluded that during the COVID-19 pandemic confinement, there was a decrease in the number of sexual offense reports due to its negative effect on the possibility of adult women reporting crimes. In addition, it was found that it is imperative to direct the criminal policies towards the general positive prevention of sexual crimes, without instrumentalising individuals, and aimed at completing a detailed follow-up of complaints.

Para ello, se aplicó una metodología mixta en las siguientes fases: primero, se analizó el registro de la Policía Nacional de Colombia -que incluyó 286 604 delitos sexuales denunciados en el periodo mencionado-. Luego, se diseñó un diagrama de bucle causal de Dinámica de Sistemas para resaltar el papel de la denuncia de delitos sexuales en el Sistema Penal Colombiano. Entre los principales hallazgos de este artículo se destaca que el 85.73 % de las denuncias están asociadas mayoritariamente a mujeres y el 68 % de las víctimas son menores de edad o adolescentes de ambos sexos. Es de anotar que la legislación colombiana divide estos delitos en agravados por violencia y no agravados por violencia. También se encontró que cuando la víctima es mujer, los delitos se presentan en mayor proporción con el agravante de violencia. También se puede concluir que durante el encierro pandémico COVID-19, hubo una disminución en el número de denuncias de delitos sexuales debido a su efecto negativo en la posibilidad de que las mujeres adultas denuncien delitos. Además, se constató que es imperativo orientar las políticas criminales hacia la prevención general positiva de los delitos sexuales, sin instrumentalizar a los individuos, y dirigidas a completar un seguimiento detallado de las denuncias.

RNAi screen in the Drosophila wing of genes encoding proteins related to cytoskeleton organization and cell division.

Cell division and cytoskeleton organization are fundamental processes participating in the development of Drosophila imaginal discs. In this manuscript we describe the phenotypes in the adult fly wing generated by knockdowns of 85% of Drosophila genes encoding proteins likely related to the regulation of cell division and cytoskeleton organization. We also compile a molecular classification of these proteins into classes that describe their expected or known main biochemical characteristics, as well as mRNA expression in the wing disc and likely protein subcellular localization for a subset of these genes. Finally, we analyze in more detail one protein family of cytoskeleton genes (Arp2/3 complex), and define the consequences of interfering with cell division for wing growth and patterning.

Development of an implantable three-dimensional model of a functional pathogenic multispecies biofilm to study infected wounds.

Chronic wounds cannot heal due to impairment of regeneration, mainly caused by the persistent infection of multispecies biofilms. Still, the effects of biofilm wound infection and its interaction with the host are not fully described. We aimed to study functional biofilms in physiological conditions in vitro, and their potential effects in health and regeneration in vivo. Therefore, Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus faecalis were seeded in collagen-based scaffolds for dermal regeneration. After 24 h, scaffolds had bacterial loads depending on the initial inoculum, containing viable biofilms with antibiotic tolerance. Afterwards, scaffolds were implanted onto full skin wounds in mice, together with daily supervision and antibiotic treatment. Although all mice survived their health was affected, displaying fever and weight loss. After ten days, histomorphology of scaffolds showed high heterogeneity in samples and within groups. Wounds were strongly, mildly, or not infected according to colony forming units, and P. aeruginosa had higher identification frequency. Biofilm infection induced leucocyte infiltration and elevated interferon-γ and interleukin-10 in scaffolds, increase of size and weight of spleen and high systemic pro-calcitonin concentrations. This functional and implantable 3D biofilm model allows to study host response during infection, providing a useful tool for infected wounds therapy development.

Tuberculosis Mortality in Children under Fifteen Years of Age: Epidemiological Situation in Colombia, 2010-2018.

Pediatric tuberculosis is a serious infectious disease and a hidden global epidemic. The objective of this study was to describe the epidemiological situation of tuberculosis mortality in children under 15 years of age in Colombia in the period 2010-2018. A longitudinal descriptive study was conducted. The variables sex, age groups, and origin were studied. This study had 260 cases for analysis and was carried out in three phases. The first phase was the determination of the sociodemographic and clinical characteristics. The second phase was the construction of indicators by territorial entities. The third phase was stratification into four epidemiological situations according to the mortality rate and years of life lost. The median age was 7 years (range 0-14), 66.5% of cases were pulmonary tuberculosis (97.7% without bacteriological confirmation), 14.3781 years of life lost were recorded (95% CI: 142.811-168.333), and in children under 10-14 years, the loss was 110,057. Amazonas had the highest adjusted YLL rate (3979.7). In total, 36.4% of the territories had a high mortality, and 30.3% adjusted to the situation designated as 1. This is the first study that has used composite indicators to address the problem of premature mortality from childhood tuberculosis in Colombia. Our results allow us to specify that this disease remains a challenge for public health. It requires models of care and differential strategies by region. It also requires ensuring opportunities in diagnosis with sensitive methods, as well as intersectoral work for the optimal approach.

Ecuaciones para la estimación del agua corporal total por el método de análisis de impedancia bioeléctrica a 50 kHz / Equations for the estimate of total body water by the method of bioelectric impedance at 50 kHz

Introducción: El agua mantiene un rango normal en personas aparentemente sanas, el cual se altera ante la existencia de diversas enfermedades. Objetivo: Conocer cuánto se diferencian los valores de agua corporal total estimados por las ecuaciones de agua corporal total, de Kushner, de Deurenberg y de Heitman, con respecto a los obtenidos clínicamente por el método de impedancia bioeléctrica a 50 kHz. Métodos: Se realizó un estudio descriptivo y transversal, de abril a diciembre del 2018, en 62 individuos: 31 adultos aparentemente sanos y 31 niños y adolescentes con diferentes enfermedades, ingresados en el Hospital Infantil Docente Sur Dr. Antonio María Béguez César de Santiago de Cuba (24 en el Servicio de Misceláneas y 7 en el de Oncopediatría). El agua corporal total y los parámetros bioeléctricos se estimaron con el analizador de impedancia bioeléctrica Bodystat® 1500-MDD, a 50 kHz, por el método tetrapolar ipsilateral derecho. Se utilizó el criterio de Bland-Altman, para un 95 % de confianza, a fin de conocer si las ecuaciones de Kushner, de Deurenberg y de Heitman podían sustituir a la ecuación de referencia. Resultados: Las ecuaciones de agua corporal total, de Kushner y de Deurenberg no mostraron diferencias significativas respecto a la ecuación de referencia, mientras que la ecuación de Heitman sí presentó diferencias significativas en relación con el resto de las ecuaciones. El método de Bland-Altman demostró que la ecuación de Kushner posee mayor concordancia con la ecuación de referencia. Conclusiones: La ecuación de Kushner es la de mayor exactitud para la estimación del agua corporal total en personas sanas y en las afectadas por entidades clínicas.

Introduction: The water maintains a normal range in apparently healthy people, which changes with the existence of diverse diseases. Objective: To know how the values of total body water estimated by Kushner, Deurenberg and Heitman equations of total body water, differ regarding those obtained clinically by the method of bioelectric impedance at 50 kHz. Methods: A descriptive and cross-sectional study was carried out, from April to December, 2018, in 62 individuals: 31 apparently healthy adults and 31 children and adolescents with different diseases, admitted to "Dr. Antonio María Béguez César" Southern Teaching Children Hospital in Santiago de Cuba (24 in the Miscellaneous Service and 7 in Oncopediatrics Service). The total body water and the bioelectric parameters were considered with the analyzer of bioelectric impedance Bodystat® 1500-MDD, at 50 kHz, for the right ipsilateral tetrapolar method. The approach of Bland-Altman was used, for 95% of confidence in order to know if Kushner, Deurenberg and Heitman equations could substitute the reference equation. Results: Kushner and Deurenberg equations of total body water didn't show significant differences regarding the reference equation, while Heitman equation presented significant differences related to the rest of the equations. The Bland-Altman method demonstrated that the equation of Kushner has higher concordance with the reference equation. Conclusions: Kushner equation has the highest accuracy for the estimate of total body water in healthy people and in those affected by diseases.

Conclusión: Una política universitaria que promueva el uso de los servicios asistenciales que brindan los centros educativos, fomenta la creación de una cultura del autocuidado y un cambio estructural en la construcción de un estilo de vida saludable en los estudiantes, lo que no implica prescindir del sistema General de Seguridad Social en Salud.

Abstract Introduction: Based on the Colombian Constitution, universities have the autonomy to develop their own healthcare service programs. Objective: To determine the factors by which young people use the healthcare services provided by the Jorge Tadeo Lozano University. Materials and methods: Using a 26-question survey, we interviewed students aged between 16 to 27 years, who have used the university healthcare facilities at least once during the period of January 13 to July 31 2017. Results: The key factors for using healthcare services were cost, habits, health professionals, environment and health promotion and prevention campaigns. Conclusion: A university policy that promotes the use of medical assistance programs provided by educational institutions encourages the establishment of a self-care culture and a structural change in the development of a healthy student lifestyle. A change that does not exclude students from using the General Social Security in Health System.

Sfrp3 modulates stromal-epithelial crosstalk during mammary gland development by regulating Wnt levels.

Mammary stroma is essential for epithelial morphogenesis and development. Indeed, postnatal mammary gland (MG) development is controlled locally by the repetitive and bi-directional cross-talk between the epithelial and the stromal compartment. However, the signalling pathways involved in stromal-epithelial communication are not entirely understood. Here, we identify Sfrp3 as a mediator of the stromal-epithelial communication that is required for normal mouse MG development. Using Drosophila wing imaginal disc, we demonstrate that Sfrp3 functions as an extracellular transporter of Wnts that facilitates their diffusion, and thus, their levels in the boundaries of different compartments. Indeed, loss of Sfrp3 in mice leads to an increase of ductal invasion and branching mirroring an early pregnancy state. Finally, we observe that loss of Sfrp3 predisposes for invasive breast cancer. Altogether, our study shows that Sfrp3 controls MG morphogenesis by modulating the stromal-epithelial cross-talk during pubertal development.

Dose-response study for the highly aggressive and metastatic primary F3II mammary carcinoma under direct current.

Electrochemical treatment has been suggested as an effective alternative to local cancer therapy. Nevertheless, its effectiveness decreases when highly aggressive primary tumors are treated. The aim of this research was to understand the growth kinetics of the highly aggressive and metastatic primary F3II tumor growing in male and female BALB/c/Cenp mice under electrochemical treatment. Different amounts of electric charge (6, 9, and 18 C) were used. Two electrodes were inserted into the base, perpendicular to the tumor's long axis, keeping about 1 cm distance between them. Results have shown that the F3II tumor is highly sensitive to direct current. The overall effectiveness (complete response + partial response) of this physical agent was ≥75.0% and observed in 59.3% (16/27) of treated F3II tumors. Complete remission of treated tumors was observed in 22.2% (6/27). An unexpected result was the death of 11 direct current-treated animals (eight females and three males). It is concluded that direct current may be addressed to significantly affect highly aggressive and metastatic primary tumor growth kinetics, including the tumor complete response.

Aspectos clínicos y epidemiológicos en pacientes con cáncer de pulmón en un servicio de neumología / Clinical and epidemiological aspects in patients with lung cancer in a pneumology service

Se realizó un estudio descriptivo y transversal de 125 pacientes con cáncer de pulmón, ingresados y diagnosticados en el Servicio de Neumología del Hospital General Docente Dr Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero de 2015 a octubre de 2016, con vistas a caracterizarles según variables clínicas y epidemiológicas de interés, además de factores de riesgo genéticos y no genéticos, independientemente de las características histológicas y el estadio clínico del proceso neoplásico. Entre los resultados preponderantes figuraron el sexo masculino y el grupo etario de 51-69 años -- aunque fue evidente el incremento del número de féminas y de pacientes en las edades más jóvenes de la vida --, igualmente la broncoscopia como método diagnóstico, la localización en el pulmón derecho, el adenocarcinoma como variedad histológica, el tabaquismo entre los factor de riesgo no genético y el parentesco de primer grado en los factores genéticos. La mayoría de los afectados presentaban menos de un año de evolución y un elevado porcentaje correspondía al estadio IV de la enfermedad.

A descriptive and cross-sectional study of 125 patients with lung cancer, admitted and diagnosed in the Pneumology Service of Dr Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba was carried out from January, 2015 to October, 2016, aimed at characterizing them according to clinical and epidemiological variables of interest, besides genetic and non genetic risk factors, independently from the histological characteristics and the clinical stage of the neoplastic process. Among the predominant results there were the male sex and the age group 51-69, although the increment of the females and of patients in the youngest ages in the life was evident --, equally the bronchoscopy as diagnostic method, the localization in the right lung, the adenocarcinoma as histological variety, smoking habit among non genetic risk factors and the first degree relation in the genetic factors. Most of the affected patients presented a clinical course shorter than a year and a high percentage were in the stage IV of the disease.

Evaluación del crecimiento y desarrollo de pacientes con síndrome Down en Santiago de Cuba / Evaluation of growth and development of patients with Down syndrome in Santiago de Cuba

Se realizó un estudio descriptivo, transversal y cuantitativo de 54 pacientes con síndrome de Down, atendidos en la consulta de Genética Clínica del Hospital Pediátrico Sur Docente Dr Antonio María Béguez César de Santiago de Cuba, desde el 2000 hasta el 2015, con el objetivo de determinar el patrón de crecimiento de los afectados. Entre las variables analizadas figuraron la edad, el sexo y los índices antropométricos: peso para la edad, talla para la edad, índice peso/talla e índice de masa corporal; asimismo, se evaluaron los defectos congénitos más frecuentes en la muestra. Se concluye que el patrón de crecimiento de dichos pacientes es similar al descrito en la bibliografía médica relacionada con el tema, lo cual puede ser útil para la atención clínica que se les debe brindar, así como también para orientar a los padres sobre los hábitos alimentarios y estilos de vida como parte del tratamiento de los niños y adolescentes con este síndrome

A descriptive, cross-sectional and quantitative study of 54 patients with Down syndrome, assisted in the Clinical Genetics Service of Dr Antonio María Béguez César Teaching Southern Children Hospital was carried out in Santiago de Cuba, from 2000 to 2015, aimed at determining the growth pattern of those affected patients. Among the analyzed variables there were age, sex and anthropometric indexes: weight according to age, height according to age, weight/height index and body mass index; also, the most frequent congenital defects were evaluated in the sample. It was concluded that the growth pattern of these patients is similar to the one described in the medical literature related to the topic, which can be useful for the clinical care that should be offered, as well as to guide the parents on the eating habits and lifestyles as part of the treatment of children and adolescents with this syndrome
