Effect of laser photocoagulation, antiangiogenic therapy or a combined treatment on refractive outcomes of newborns with ROP.

PURPOSE: To determine the refractive outcome after treatment with laser photocoagulation, intravitreal antiangiogenic injection or both, for the treatment of type 1 ROP and/or aggressive posterior ROP using defocus equivalent terms. These results will be compared with the spherical equivalent (SE) notation in an initial refraction (during the first 3 years after treatment) and in a final evaluation (three years after treatment). METHODS: Clinical charts review of preterm patients who developed type 1 ROP and/or aggressive posterior ROP who were treated with laser photocoagulation, intravitreal antiangiogenic injection, or both, between January 2007 and December 2014 at Fundación Oftalmológica de Santander were reviewed. Refractive error was evaluated at two different time points in three different treatment groups. RESULTS: Seventy-seven eyes (56 patients) with ROP diagnosis treated with laser, antiangiogenics or in a combined scheme were included. Median gestational age was 29 weeks (IQR = 3), median birth weight was 1100 (IQR = 335) and mean corrected age at the time of treatment was 37.3 weeks (SD 2.2). Refractive outcomes in SE terms for the first refraction had a median of -0.50 diopters and in defocus terms, 4.00 diopters (D). For the second refraction, -3.00 diopters and 4.00 diopters (D), respectively. Pearson correlation test result for the first measurement was 93% (p = 0.000) and for the second evaluation was 99% (p = 0.000). CONCLUSIONS: Low birth weight had a statistically significant association to the increase of the refractive outcome. The high correlation between SE and DE for refractive errors allows us to confirm that DE is an appropriate metric to report refractive outcomes in this group of patients due to the presence of combined refractive ametropias.

Cambios en la composición corporal y ángulo de fase durante la pretemporada en jugadores de fútbol profesional / Changes in body composition and phase angle during pre-season in professional soccer players

RESUMEN: El análisis y el control de la composición corporal son claves en el fútbol por su implicación en el rendimiento. El objetivo de este estudio fue identificar, en jugadores de futbol profesional, el ángulo de fase (PhA) de miembros inferiores con los posibles patrones de mejora del componente magro en los mismos medido por DEXA. Al mismo tiempo, se estudió mediante BIA la evolución de parámetros hídricos de los jugadores, sometidos a un entrenamiento intenso y a un control nutricional de su alimentación y suplementación. Se evaluaron a 18 jugadores (26,28 ± 5,1 años; 85,09 ± 9,16 kg; 185,5 ± 4,32 cm) de un equipo de la primera división de fútbol italiana. Se llevó a cabo el estudio durante cuatro semanas, entre el 11 de julio (pre-test) y el 11 de agosto de 2021 (post-test). La intervención se llevó a cabo en su totalidad en pretemporada, con un confinamiento en modalidad de aislamiento o burbuja total por prevención al contagio del COVID-19, dónde se monitorizaba en un alto porcentaje la vida del jugador, incluyendo factores como la alimentación, el entrenamiento y el descanso. La suplementación estuvo basada en antioxidantes, multivitamínicos, minerales y ácidos grasos poliinsaturados y dos productos en polvo (uno a base de creatina, glutamina y leucina, y otro, a base de aminoácidos esenciales). Los jugadores presentaron una mejora del PhA y del componente magro en los miembros inferiores, con una moderada correlación (r = 0,6). Con respecto al agua intracelular y extracelular, señalar que, a pesar de la alta intensidad del ejercicio durante cuatro semanas, éstas se han mantenido constantes sin presentar variaciones significativas durante el periodo de estudio, lo que indica que no se ha producido un proceso de deshidratación del jugador.

SUMMARY: The analysis and control of body composition is essential in soccer due to its implication in performance. The aim of this study was to identify, in professional soccer players, the phase angle (PhA) of the lower limbs with possible patterns of improvement of the lean component measured by DEXA. At the same time, the evolution of hydric parameters of the players, subjected to intense training and nutritional control of their diet and supplementation, was studied by means of BIA. Eighteen players (26.28 ± 5.1 years; 85.09 ± 9.16 kg; 185.5 ± 4.32 cm) from an Italian first division football team were evaluated. The study was conducted for four weeks, between 11th July (pre- test) and 11th August of 2021 (post-test). The intervention was carried out entirely in pre-season, with confinement in isolation or total bubble mode for prevention of COVID-19 infection, where a high percentage of the player's life was monitored, including factors such as diet, training and rest. Supplementation was based on antioxidants, multivitamins, minerals and polyunsaturated fatty acids and two powdered products (one based on creatine, glutamine and leucine, and the other one, on essential amino acids). The players showed an improvement in PhA and in the lean component in the lower limbs, with a moderate correlation (r = 0.6). With regard to intracellular and extracellular water, it should be noted that, despite the high intensity of exercise during four weeks, these have remained constant without significant variations during the study period, indicating that there has not been a process of dehydration of the player.

The impact of the stratification by degree of clinical severity and abandonment risk of tuberculosis treatment.

OBJECTIVE: Evaluate the impact of the instrument of the "Stratification by Degree of Clinical Severity and Abandonment Risk of Tuberculosis Treatment" (SRTB) on the tuberculosis outcome. METHODS: This study was a pragmatic clinical trial involving patients with a confirmed diagnosis of tuberculosis treated at one of the 152 primary health care units in the city of Belo Horizonte, Brazil, between May of 2016 and April of 2017. Cluster areas for tuberculosis were identified, and the units and their respective patients were divided into intervention (use of SRTB) and nonintervention groups. RESULTS: The total sample comprised 432 participants, 223 and 209 of whom being allocated to the nonintervention and intervention groups, respectively. The risk of treatment abandonment in the nonintervention group was significantly higher than was that in the intervention group (OR = 15.010; p < 0.001), regardless of the number of risk factors identified. Kaplan-Meier curves showed a hazard ratio of 0.0753 (p < 0.001). CONCLUSIONS: The SRTB instrument was effective in reducing abandonment of tuberculosis treatment, regardless of the number of risk factors for that. This instrument is rapid and easy to use, and can be adapted to different realities. Its application showed characteristics predisposing to a non-adherence to the treatment and established bases to mitigate its impact.

Macular and choroidal thicknesses in a healthy Hispanic population evaluated by high-definition spectral-domain optical coherence tomography (SD-OCT).

PURPOSE: To report normal values of macular and choroidal thickness obtained from a healthy Hispanic population using Optovue (Optovue Inc, Freemont CA, USA) spectral domain optical coherence tomography (SD-OCT). DESIGN: Observational, cross-sectional, correlation study. METHODS: A total of 290 eyes (145 healthy subjects) were included; 69% of subjects were female. The median age was 39 ± 29 years (IQR), with a range between 18 and 89 years. The study sample was stratified into three age groups: Group 1, 18-40 years (50.3%), Group 2, 41-60 years (30.7%), and Group 3, older than 61 years (19%). Central macular, perifoveal (inner quadrants), and parafoveal (outer quadrants) thicknesses were estimated. In addition, central and peripheral choroidal thicknesses were estimated. Data analysis was performed to calculate the standardized mean difference according to the variance (Student's t-test) and its differences with Epidat 4.1. RESULTS: Median macular central thickness was 250 ±30 µm (IQR) with Optovue. Median central choroidal thickness was 263 ± 48 µm (IQR). Median central choroidal thickness was greater than mean peripheral thickness. Macular evaluation showed a statistically significant difference in central, perifoveal, and parafoveal thicknesses, with lower values being recorded for the study sample compared with the manufacturer's data. CONCLUSIONS: SD-OCT has become a useful tool to obtain high-resolution images of the macula and choroid. This method allows precise assessment of the retinal and choroidal layers to diagnose and follow up posterior segment diseases. We are reporting normal cut-off values of macular and choroidal thicknesses in healthy Hispanic subjects evaluated with Optovue SD-OCT as new diagnostic normal parameters for research and clinical activities.

An Origin of Citations: Darwin's Collaborators and Their Contributions to the Origin of Species.

In the first edition of the Origin of Species (1859), Charles Darwin apologized for not correctly referencing all the works cited in his magnum opus. More than 150 years later we have catalogued these citations and analyzed the resultant data. Looking for a complete selection of collaborators, a flexible interpretation of the term citation was necessary; we define it as any reference made to a third party, independently of its form or function. Following the same idea, the sixth edition of the Origin, originally published in 1872 and reprinted with minor additions and corrections in 1876, was chosen for the research because it represents the end of a long debate between Darwin and his peers. It naturally is the edition with the greatest number of citations and collaborators. Through a diverse theoretical analysis, we aim to present a new perspective for the study of the Origin of Species: a bibliographic approach that provides the tools needed to understand the history of the book as a physical and cultural object. Bibliometrics provides a theory of citations as well as a quantitative analysis; science studies highlights the profound social aspects of science in the making. The analysis resulted in 639 citations to 298 collaborators and provided a new perspective of the rhetorical structure of the Origin, even though these results are only the tip of the iceberg of the potential of all the data gathered in this study.

Prevalence of latent Mycobacterium tuberculosis infection in renal transplant recipients / Prevalência da infecção latente por Mycobacterium tuberculosis em transplantados renais

ABSTRACT Objective: To estimate the prevalence of latent Mycobacterium tuberculosis infection (LTBI) in renal transplant recipients and to assess sociodemographic, behavioral, and clinical associations with positive tuberculin skin test (TST) results. Methods: This was a cross-sectional study of patients aged ≥ 18 years who underwent renal transplantation at the Renal Transplant Center of the Federal University of Minas Gerais Hospital das Clínicas, located in the city of Belo Horizonte, Brazil. We included renal transplant recipients who underwent the TST between January 2011 and July 2013. If the result of the first TST was negative, a second TST was administered. Bivariate and multivariate analyses using logistic regression were used to determine factors associated with positive TST results. Results: The sample included 216 patients. The prevalence of LTBI was 18.5%. In the multivariate analysis, history of contact with a tuberculosis case and preserved graft function (estimated glomerular filtration rate ≥ 60 mL/min/1.73 m2) were associated with positive TST results. TST induration increased by 5.8% from the first to the second test, which was considered significant (p = 0.012). Conclusions: The prevalence of LTBI was low in this sample of renal transplant recipients. The TST should be administered if renal graft function is preserved. A second TST should be administered if the first TST is negative.

RESUMO Objetivo: Estimar a prevalência da infecção latente por Mycobacterium tuberculosis (ILTB) em transplantados renais e avaliar as associações sociodemográficas, comportamentais e clínicas com a prova tuberculínica (PT) positiva. Métodos: Estudo transversal, com pacientes com idade ≥ 18 anos, transplantados renais no Centro de Transplante Renal do Hospital das Clínicas da Universidade Federal de Minas Gerais, em Belo Horizonte (MG). Foram incluídos os pacientes submetidos a transplante renal que realizaram a PT no período entre janeiro de 2011 e julho de 2013. Quando o resultado da primeira PT foi negativo, uma segunda PT foi realizada. As análises bivariada e multivariada, por meio de regressão logística, foram utilizadas para determinar os fatores associados com PT positiva. Resultados: A amostra incluiu 216 pacientes. A taxa de prevalência para ILTB foi de 18.5%. Na análise multivariada, história de contato com caso de tuberculose e função do enxerto preservada (taxa de filtração glomerular estimada ≥ 60 ml/min/1,73 m2) foram associadas com PT positiva. O incremento da primeira PT para a segunda PT foi de 5,8%, considerado significante (p = 0,012). Conclusões: A prevalência da ILTB foi baixa nessa amostra de pacientes transplantados renais. A PT deve ser efetuada quando a função do enxerto renal estiver preservada. Uma segunda PT deve ser realizada quando a primeira PT for negativa.

A second TST should be administered if the first TST is negative.

"ciência sem fronteiras" como acontecimento discursivo e dispositivo de poder/saber / "science without borders" as a discoursive event and power/knowledge device

RESUMO: A ideia de que internacionalizar a educação é tarefa da qual o ensino superior no país não pode escapar mobiliza as discussões realizadas ao longo deste artigo. Assim, a partir da premissa de que o chamado Programa Ciência sem Fronteiras se configura como um dispositivo de poder/saber, refletimos sobre as regularidades discursivas e os efeitos de poder vinculados a um conjunto de enunciados que tem como referencial a internacionalização da educação. Primeiramente, discutimos o programa como acontecimento discursivo e dispositivo de governamentalidade; em seguida, analisamos sequências enunciativas retiradas de um arquivo mais abrangente, composto por documentos e entrevistas feitas a sujeitos que tiveram uma experiência educacional com esse programa. As discussões encontram-se calcadas em levantamento bibliográfico, pesquisa documental e entrevistas narrativas (BAUER & GASKEL, 2002), Também valemo-nos do método arquegenealógico, com base em Foucault (1999, 2008, 2014, 2015), bem como Deleuze (2011), Veyne (2011) e Navarro (2004, 2011, 2015).

ABSTRACT: The idea that internationalizing education is a task that higher education in Brazil can't escape from mobilizes discussions carried out throughout this article. Based on the premise that Science Without Borders Program is configured as a power/knowledge device, we reflect on discursive regularities and power effects linked to a set of statements that have the internationalization of education as a reference. At first, we discussed the program as a discursive event and as a device of governmentality; afterwards, we analyzed some enunciative sequences taken from a more comprehensive database, composed of documents and interviews done to subjects who had educational experience with this program. The discussions are based on bibliographical research, documentary research and narrative interviews (BAUER & GASKEL, 2002). In addition to the discursive analysis of this material, we use the archegenealogical method developed by Foucault (1999, 2008, 2014, 2015), as well as Deleuze (2011), Veyne (2011) and Navarro (2004, 2011, 2015).

Prevalence of hypothyroidism in major psychiatric disorders in hospitalised patients in Montserrat Hospital during the period March to October 2010 / Prevalencia de hipotiroidismo en trastorno psiquiátrico mayor de pacientes hospitalizados en la Clínica Montserrat en el periodo de marzo a octubre de 2010

Abstract Introduction: Hypothyroidism results from inadequate production of thyroid hormone. It is known that there is a relationship between the major psychiatric disorders and hypothyroidism. Objective: To determine the prevalence of hypothyroidism in patients admitted due to major psychiatric disorders in Montserrat Hospital during the period from March to October 2010. Material and methods: A descriptive cross-sectional study was conducted on 105 patients admitted to Montserrat Hospital with a primary diagnosis of major psychiatric disorder (major depression, bipolar affective disorder, generalised panic disorder, panic disorder, mixed anxiety-depressive disorder, and schizophrenia) in the aforementioned period. Thyroid stimulating hormone (TSH) was performed to assess the evidence of hypothyroidism. Results: The overall prevalence of hypothyroidism was found to be 10.5% (95%CI, 5-16%). It was 12.5% in anxiety disorder, 11.1% in depressive disorder, with a lower prevalence of 10.3% for bipolar disorder, and 9.9% for schizophrenia. Conclusions: The overall prevalence of hypothyroidism was found to be less than in the general population, which is between 4.64% and 18.5%, and hypothyroidism was found in disorders other than depression.

Resumen Introducción: El hipotiroidismo resulta de una inadecuada producción de hormonas tiroideas. Es conocido que existe una relación entre los trastornos psiquiátricos mayores y el hipotiroidismo. Objetivo: Determinar la prevalencia de hipotiroidismo en los pacientes hospitalizados por trastorno psiquiátrico mayor en la Clínica Montserrat en el periodo de marzo a octubre de 2010. Material y métodos: Se realizó un estudio descriptivo transversal, para el que se seleccionó una muestra de 105 pacientes que ingresaron a la Clínica Montserrat con diagnóstico de trastorno psiquiátrico mayor (depresión mayor, trastorno afectivo bipolar, trastorno de ansiedad generalizada, trastornos de ansiedad, trastorno mixto ansioso-depresivo y esquizofrenia) en el periodo mencionado. Para evaluar el hipotiroidismo se realizó una prueba de Hormona Estimulante del Tiroides (TSH). Resultados: La prevalencia general del hipotiroidismo fue del 10,5% (intervalo de confianza del 95%, 5%-16%). Al determinar el hipotiroidismo por diagnóstico, se encontró que había mayor prevalencia en los trastorno de pánico (12,5%) y depresivo (11,1%) y menor en el trastorno bipolar (10,3%) y la esquizofrenia (9,9%). Conclusiones: La prevalencia general del hipotiroidismo fue menor que en la población general (18,5-4,6%) y se encontró hipotiroidismo en otros trastornos diferentes de la depresión.

Prevalence of latent Mycobacterium tuberculosis infection in prisoners.

OBJECTIVE:: To determine the prevalence of and the factors associated with latent Mycobacterium tuberculosis infection (LTBI) in prisoners in the state of Minas Gerais, Brazil. METHODS:: This was a cross-sectional cohort study conducted in two prisons in Minas Gerais. Tuberculin skin tests were performed in the individuals who agreed to participate in the study. RESULTS:: A total of 1,120 individuals were selected for inclusion in this study. The prevalence of LTBI was 25.2%. In the multivariate analysis, LTBI was associated with self-reported contact with active tuberculosis patients within prisons (adjusted OR = 1.51; 95% CI: 1.05-2.18) and use of inhaled drugs (adjusted OR = 1.48; 95% CI: 1.03-2.13). Respiratory symptoms were identified in 131 (11.7%) of the participants. Serological testing for HIV was performed in 940 (83.9%) of the participants, and the result was positive in 5 (0.5%). Two cases of active tuberculosis were identified during the study period. CONCLUSIONS:: Within the prisons under study, the prevalence of LTBI was high. In addition, LTBI was associated with self-reported contact with active tuberculosis patients and with the use of inhaled drugs. Our findings demonstrate that it is necessary to improve the conditions in prisons, as well as to introduce strategies, such as chest X-ray screening, in order to detect tuberculosis cases and, consequently, reduce M. tuberculosis infection within the prison system. OBJETIVO:: Determinar a prevalência e os fatores associados à infecção latente por Mycobacterium tuberculosis (ILTB) em pessoas privadas de liberdade no Estado de Minas Gerais. MÉTODOS:: Estudo de coorte transversal realizado em duas penitenciárias em Minas Gerais. Foi realizada a prova tuberculínica nos indivíduos que aceitaram participar do estudo. RESULTADOS:: Foram selecionados 1.120 indivíduos para a pesquisa. A prevalência da ILTB foi de 25,2%. Na análise multivariada, a ILTB esteve associada com relato de contato com caso de tuberculose ativa dentro da penitenciária (OR ajustada = 1,51; IC95%: 1,05-2,18) e uso de drogas inaláveis (OR ajustada = 1,48; IC95%: 1,03-2,13). Foram identificados 131 pacientes sintomáticos respiratórios (11,7%). O teste anti-HIV foi realizado em 940 (83,9%) dos participantes, sendo positivo em 5 indivíduos (0,5%). Dois casos de tuberculose ativa foram identificados no período do estudo. CONCLUSÕES:: A prevalência de ILTB dentro das penitenciárias estudadas foi alta. Além disso, a ILTB estava associada ao relato de contato com casos de tuberculose e ao uso de drogas inaláveis. Nossos achados demonstram que é necessária a melhoria das condições de encarceramento e a utilização de outras estratégias, como a triagem por radiografia de tórax, para a descoberta de casos de tuberculose e redução da infecção pelo M. tuberculosis no sistema penitenciário.

Valoración de la adopción de embriones humanos congelados desde el punto de vista de la filosofía moral, la ética laica y dos religiones monoteístas / Valuating frozen human embryo adoption from a moral philosophical point of view, lay ethics and two monotheist religions / Valoração da adoção de embriões humanos congelados do ponto de vista da filosofia moral, a ética laica e duas religiões monoteístas

La búsqueda de la eficacia en la fecundación in vitro hace que se produzcan más embriones que los que se implantarán, lo que produce un excedente de embriones, que es congelado. Esto hace que ineludiblemente el número de embriones humanos congelados aumente. Entre las soluciones para dichos embriones humanos congelados está la donación/adopción de los mismos. Ineludiblemente esta práctica conlleva objetivos problemas éticos. En este trabajo se evalúa la eticidad de la donación/adopción de embriones humanos congelados desde la perspectiva de la filosofía moral, lo que podríamos llamar una "ética laica" y dos de las religiones monoteístas: la musulmana y la judía.

The search for IVF efficacy leads to a higher embryo production than it is necessary for implantation; this results in an excess of embryos which are kept frozen. This amount of frozen embryos inevitably increases. The donation/adoption are among the possible solutions for these frozen embryos. However, this practice has objective ethical problems. This article considers the ethical aspects of the donation / adoption of frozen human embryos from the point of view of moral philosophy, from what we could call "secular ethics" and from two monotheistic religions: Muslim and Jewish.

Prevalence of latent Mycobacterium tuberculosis infection in prisoners / Prevalência da infecção latente por Mycobacterium tuberculosis em pessoas privadas de liberdade

ABSTRACT Objective: To determine the prevalence of and the factors associated with latent Mycobacterium tuberculosis infection (LTBI) in prisoners in the state of Minas Gerais, Brazil. Methods: This was a cross-sectional cohort study conducted in two prisons in Minas Gerais. Tuberculin skin tests were performed in the individuals who agreed to participate in the study. Results: A total of 1,120 individuals were selected for inclusion in this study. The prevalence of LTBI was 25.2%. In the multivariate analysis, LTBI was associated with self-reported contact with active tuberculosis patients within prisons (adjusted OR = 1.51; 95% CI: 1.05-2.18) and use of inhaled drugs (adjusted OR = 1.48; 95% CI: 1.03-2.13). Respiratory symptoms were identified in 131 (11.7%) of the participants. Serological testing for HIV was performed in 940 (83.9%) of the participants, and the result was positive in 5 (0.5%). Two cases of active tuberculosis were identified during the study period. Conclusions: Within the prisons under study, the prevalence of LTBI was high. In addition, LTBI was associated with self-reported contact with active tuberculosis patients and with the use of inhaled drugs. Our findings demonstrate that it is necessary to improve the conditions in prisons, as well as to introduce strategies, such as chest X-ray screening, in order to detect tuberculosis cases and, consequently, reduce M. tuberculosis infection within the prison system.

RESUMO Objetivo: Determinar a prevalência e os fatores associados à infecção latente por Mycobacterium tuberculosis (ILTB) em pessoas privadas de liberdade no Estado de Minas Gerais. Métodos: Estudo de coorte transversal realizado em duas penitenciárias em Minas Gerais. Foi realizada a prova tuberculínica nos indivíduos que aceitaram participar do estudo. Resultados: Foram selecionados 1.120 indivíduos para a pesquisa. A prevalência da ILTB foi de 25,2%. Na análise multivariada, a ILTB esteve associada com relato de contato com caso de tuberculose ativa dentro da penitenciária (OR ajustada = 1,51; IC95%: 1,05-2,18) e uso de drogas inaláveis (OR ajustada = 1,48; IC95%: 1,03-2,13). Foram identificados 131 pacientes sintomáticos respiratórios (11,7%). O teste anti-HIV foi realizado em 940 (83,9%) dos participantes, sendo positivo em 5 indivíduos (0,5%). Dois casos de tuberculose ativa foram identificados no período do estudo. Conclusões: A prevalência de ILTB dentro das penitenciárias estudadas foi alta. Além disso, a ILTB estava associada ao relato de contato com casos de tuberculose e ao uso de drogas inaláveis. Nossos achados demonstram que é necessária a melhoria das condições de encarceramento e a utilização de outras estratégias, como a triagem por radiografia de tórax, para a descoberta de casos de tuberculose e redução da infecção pelo M. tuberculosis no sistema penitenciário.

[Structure and Family Type in Patients With Substance Abuse or Dependence Psychoactive Rehabilitation Center of Addiction in the Municipality of Chia Cundinamarca]. / Estructura y tipología familiar en pacientes con dependencia o abuso de sustancias psicoactivas en un centro de rehabilitación de adicciones en el Municipio de Chía, Cundinamarca.

OBJECTIVE: To determine the family type, family structure in a group of patients with a diagnosis of substance abuse or dependence who were at a rehabilitation center for addiction during the period between August and October 2009. METHODS: Through a descriptive qualitative-interpretative methodology 10 patients who met inclusion criteria for substance dependence or abuse were studied. The fieldwork and transcripts were made for three months by non-participant observation, non-structured interviews and examination of patients' clinical history. RESULTS: Seven of the families interviewed were single-parent families with an unconventional organization on "gender roles". Single-parent families favored loneliness, difficulty in rule-setting, de-idealization of the place of the father in the family structure and a constant search for complicity. In the analysis by categories, we found that in 10 families in the study of individuals with addictions it is common to find family structure characteristics such as inadequate communication, lack of authority rules and limits, presence of triangulations, the lack of cohesion due to the existence of a disconnected relationship pattern and changed roles compared to conventional gender. The search for the affection of the mother at her emotional overload absence of roles and lack of father, raised by the separation of the couple, was found as an essential aspect underlying the addictive behavior. A pattern of parental abandonment is configured. CONCLUSION: The findings confirmed what has been mentioned by various authors regarding the characteristics of the family typology structure and personal factors in patients with addictions, in addition to their need for affection combined with the desire for the mother's presence. The family typology does not determine for itself the abuse of psychoactive substances, but the influence of other factors such as family structure, especially deficient affective interactions, which should be considered in the development of therapeutic strategies.
