Prevalencia de hipertirotropinemia neonatal comoindicador de deficiencia de yodo en la provincia de La Pampa: un análisis epidemiológico / Prevalence of high neonatal thyroid stimulating hormone levels as an indicator of iodine deficiency in the province of La Pampa: An epidemiological analysis

Introducción. El yodo desempeña un rol fundamental en el metabolismo, el crecimiento y el desarrollo humano. Durante el embarazo y la infancia, la demanda de este micronutriente aumenta considerablemente. La tirotropinemia neonatal (TSHn) aumentada, definida como TSHn ≥5 mUI/l, es un marcador que señala la deficiencia de yodo en una población cuando su prevalencia supera el 3 %. Objetivo. Determinar la prevalencia de TSHn ≥ 5 en La Pampa durante el período 2021-2022, analizar su correlación con diferentes variables y compararla con datos de una cohorte histórica. Población y métodos. Estudio transversal, de diseño descriptivo-analítico, sobre una población de neonatos nacidos en las cinco zonas sanitarias de la provincia de La Pampa durante los años 2021 y 2022. Resultados. De los 5778 neonatos evaluados, el 9,6 % presentó niveles de TSHn ≥5 mUI/l. El 70,4 % de estas mediciones fueron realizadas después del tercer día de vida. No se observaron diferencias significativas en la frecuencia de niveles elevados de TSHn según el año de nacimiento, peso al nacer o días hasta la extracción. Se registró una mayor prevalencia en el sexo masculino (10,6 % versus 8,5 %; p = 0,007) y entre los neonatos nacidos a término (9,8 % versus 6,6 %; p = 0,02). La prevalencia de hipertirotropinemia fue superior a la observada en una cohorte de 2001-2002. Conclusiones. La prevalencia de hipertirotropinemia neonatal en La Pampa durante los años 2021 y 2022 fue del 9,6 %, lo que indica un estado de deficiencia leve de yodo en la provincia, superior al reportado hace dos décadas.

Introduction. Iodine plays a key role in human metabolism, growth, and development. During pregnancy and childhood, the demand for this micronutrient increases notably. Increased neonatal thyroid stimulating hormone (nTSH) levels, defined as nTSH ≥ 5 mIUL, are a marker of iodine deficiency in a population if its prevalence is higher than 3%.Objective. To establish the prevalence of nTSH ≥ 5 in La Pampa in the 2021­2022 period, analyze its correlation with different variables, and compare it with data from a historical cohort.Population and methods. Cross-sectional, descriptive-analytical study in a population of newborn infants born in the 5 health regions of the province of La Pampa in 2021 and 2022. Results. Of  the  5778  assessed  newborn  infants,  9.6%  had  nTSH  levels  ≥  5  mIU/L. It was reported that 70.4% of these measurements were done after the third day of life. No significant differences were observed in the frequency of high nTSH levels by year of birth, birth weight, or days until samplecollection.A higher prevalence was observed among male infants (10.6% versus 8.5%; p = 0.007) and term infants (9.8% versus 6.6%; p = 0.02). The prevalence of high TSH levels was superior to that observed in the 2001­2002 cohort. Conclusions. The  prevalence of high nTSH levels in La Pampa during 2021 and 2022 was 9.6%, suggesting the presence of mild iodine deficiency in the population of this province, higher that what  had been reported 2 decades ago.

[Risk of malnutrition and food insecurity in pediatric cancer patients. The NutriCare Study]. / Riesgo de desnutrición e inseguridad alimentaria en pacientes pediátricos con cáncer. Estudio NutriCare.

Introduction: Introduction: cancer and its treatments have been associated with poor nutritional status in children and adolescents. Objective: to establish the nutritional risk of pediatric patients and the degree of food and nutritional insecurity in the homes of children and adolescents with cancer who have been hospitalized in a high complexity pediatric oncology center. Methods: a prospective observational study conducted at the Fundación Hospital Pediátrico la Misericordia - HOMI. It included a sample of 41 children and adolescents aged 0 to 17 years and 11 months with a diagnosis of childhood cancer during the study period. The participants recruited during hospitalization had the application of the SCAN nutritional screening tool for childhood cancer, Spanish version, validated in HOMI and the Latin American and Caribbean Scale of Food and Nutritional Security - ELCSA, adapted and validated in Colombia. Results: 76 % (n = 31) of the patients were classified as "At risk of malnutrition" using the SCAN-SP nutritional screening tool. It was observed that 56 % of all households had a proportion of food insecurity, of which the classification of food insecurity was mild in 29 %, moderate in 20 % and severe in 7 % of households with children under 18 years of age. Conclusion: in the framework of the nutritional care process, it is important to take into account factors that include a complete nutritional risk assessment and evaluation that includes the measurement of food security.

Se observó que el 56 % del conjunto de hogares tenían inseguridad alimentaria, siendo la clasificación de la inseguridad alimentaria leve en el 29 %, moderada en el 20 % y severa en el 7 % de los hogares con menores de 18 años. Conclusión: en el proceso de cuidado integral en oncología pediátrica, el marco nutricional es de vital importancia; por esto, tener en cuenta factores que incluyan no solo la evaluación del riesgo y la valoración nutricional completa sino también la medición objetiva de la seguridad alimentaria siempre deben incluirse.

Cribado prenatal de aneuploidías mediante análisis de ácido desoxirribonucleíco libre total circulante en plasma materno. Revisión narrativa / Prenatal screening for aneuploidies by analysis of circulating total free deoxyribonucleic acid in maternal plasma. Narrative review

La prueba prenatal no invasiva es un método de cribado de aneuploidías fetales y de resultar con riesgo alto debe ser confirmado a través de prueba genética diagnóstica. Es la prueba de detección más sensible y específica para las aneuploidías fetales comunes y minimiza la realización de técnicas invasivas, solo para las gestantes con riesgo elevado. Se debe realizar asesoramiento genético pre- y poscribado. Este estudio tiene como objetivo describir los fundamentos básicos de la prueba prenatal no invasiva mediante el análisis del ácido desoxirribonucleíco libre circulante en plasma materno para cribado de aneuploidías, y de los métodos primordiales y avances en biología molecular incluyendo las tecnologías de secuenciación de nueva generación, que lo han facilitado, considerando sus beneficios y limitaciones al aplicarla en la práctica clínica, en este campo que cambia con tanta rapidez(AU)

The non-invasive prenatal test is a screening method for fetal aneuploidies and if the result is at high risk, it must be confirmed through diagnostic genetic test. It is the most sensitive and specific detection test for common fetal aneuploidies and minimizes the use of invasive techniques, only for pregnant women at high risk. Genetic counseling should be performed before and after screening. This study aims to describe the basic fundamentals of non-invasive prenatal testing by analyzing free circulating deoxyribonucleic acid in maternal plasma for aneuploidy screening, and the primary methods and advances in molecular biology, including next-generation sequencing technologies, which have facilitated it, considering its benefits and limitations when applying it in clinical practice, in this rapidly changing field(AU)

Evaluation of a HIV screening strategy in the hospital setting to reduce undiagnosed infection.

INTRODUCTION: In Spain, half of new HIV diagnoses are late and a significant proportion of people living with HIV have not yet been diagnosed. Our aim was to evaluate the effectiveness of an automated opportunistic HIV screening strategy in the hospital setting. METHODS: Between April 2022 and September 2023, HIV testing was performed on all patients in whom a hospital admission analytical profile, a pre-surgical profile and several pre-designed serological profiles (fever of unknown origin, pneumonia, mononucleosis, hepatitis, infection of sexual transmission, rash, endocarditis and myopericarditis) was requested. A circuit was started to refer patients the specialists. RESULTS: 6407 HIV tests included in the profiles were performed and 18 (0.3%) new cases were diagnosed (26.4% of diagnoses in the health area). Five patients were diagnosed by hospital admission and pre-surgery profile and 13 by a serological profile requested for indicator entities (fever of unknown origin, sexually transmitted infection, mononucleosis) or possibly associated (pneumonia) with HIV occult infection. Recent infection was documented in 5 (27.8%) patients and late diagnosis in 9 (50.0%), of whom 5 (55.5%) had previously missed the opportunity to be diagnosed. CONCLUSIONS: This opportunistic screening was profitable since the positive rate of 0.3% is cost-effective and allowed a quarter of new diagnoses to be made, so it seems a good strategy that contributes to reducing hidden infection and late diagnosis.

Características de recién nacidos hijos de madre con IgM positiva para el Virus Herpes Simplex

Introducción: El herpes connatal es una entidad infrecuente asociada a elevada morbimortalidad. La probabilidad de transmisión al recién nacido va de 5% al 85%. El diagnóstico se dificulta por falta de clínica, serología no confiable y por la no disponibilidad de PCR en los servicios públicos de países en vías de desarrollo. La IgM en gestantes podría ser utilizada como un marcador de sospecha para evaluar al neonato. Objetivo: Caracterizar a los recién nacidos, hijos de gestantes con IgM positiva para HVS 1-2 y la frecuencia de encefalitis en los infantes. Materiales y métodos : Estudio observacional, descriptivo, prospectivo, realizado de mayo de 2020 a octubre de 2021. Se incluyeron recién nacidos (RN) de madres con IgM positiva para Herpes Virus Simplex (HVS) a partir de la segunda mitad del embarazo. En el RN se realizó serología IgG e IgM, y además, PCR- RT para HVS 1-2 en sangre y/o LCR, excluyéndose los nacidos en otras maternidades y/o sin datos de serología materna. Resultados: 36 pacientes. Edad materna 28 años (DS + 4), 5% con antecedentes de HVS, 61% cesárea. 36% prematuros, 13% RCIU. Síntomas agudos en el RN 22%. De ellos, 19% plaquetopenia, 44% alteración de GOT. 63% PCR HVS en sangre y 44% en LCR. Se encontró hemorragia, hidrocefalia, leucomalacia en 27%. No se encontró diferencias en la expresión clínica por tipo de parto. Conclusiones: Los RN hijos de gestantes con IgM positiva para VHS desde la segunda mitad del embarazo o periparto, presentaron infección por VHS determinada por PCR en sangre o LCR, independiente de la vía del parto. El diagnóstico serológico en embarazadas permite la pesquisa, diagnóstico y tratamiento temprano del RN.

Introduction: neonatal herpes is a rare entity associated with high morbidity and mortality. The probability of transmission to the newborn ranges from 5% to 85%. The diagnosis is difficult due to the lack of clinical signs, unreliable serology and the non-availability of PCR in public services in developing countries. IgM in pregnant women could be used as a suspected marker to evaluate the neonate. Objective: To characterize newborn children of pregnant women with positive IgM for HSV 1-2 and the prevalence of encephalitis in infants. Materials and methods: Observational, descriptive, prospective study, carried out from May 2020 to October 2021. Newborns (NB) of mothers with positive IgM for Herpes Virus Simplex (HSV) from the second half of pregnancy were included. In newborns, IgG and IgM were performed, and in addition, PCR-RT for HSV 1-2 in blood and/or CSF, excluding those born in other hospitales and/or without maternal serology data. Results: We included 36 patients. Maternal age was 28 years (DS + 4), 5% with a history of HSV. 61% were delivered via cesarean section, 36% were premature, 13% had IUGR. 22% of the newborns had acute symptoms. 19% had thrombocytopenia, 44% had GOT alteration. 63% were PCR positive for HSV in serum and 44% were CSF-positive. Hemorrhage, hydrocephalus and leukomalacia were found in 27%. No differences were found in clinical expression by type of delivery. Conclusions: Newborns born to pregnant women with positive IgM for HSV from the second half of pregnancy or peripartum, presented HSV infection as determined by PCR in blood or CSF, regardless of the route of delivery. Serological diagnosis in pregnant women allows early screening, diagnosis and treatment of the NB.

Estandarización de requerimientos mínimos para la formación de centro de detección temprana de cáncer de pulmón en América Latina / Standardization of Minimum Requirements for the Formation of an Early Detection Center for Lung Cancer in Latin America

Introducción: El cáncer de pulmón (CP) es una enfermedad con gran impacto a nivel mundial en el número de muertes y en costos en salud. La alta incidencia y mortalidad de esta enfermedad asociada al diagnóstico tardío, y la mejoría del pronóstico ante una detección temprana, determinan que sea una patología pasible de beneficiarse mediante detección temprana. La tomografía de baja dosis de radiación (TCBD) demostró ser un método que se pue- de realizar periódicamente a un grupo de personas con alto riesgo de desarrollar CP y así reducir la mortalidad por esta enfermedad. Sin embargo, este beneficio es tal cuan- do se encuentra desarrollado bajo un programa organizado y con participación multi- disciplinaria especializada en cáncer de pulmón. Métodos: Se plantea determinar lineamientos básicos para el desarrollo de la detección temprana de cáncer de pulmón en América Latina para que pueda ser realizada en forma uniforme, con el menor riesgo y el máximo beneficio esperado. Se analizaron las principales publicaciones referidas a este tema, contemplando la diversidad de atención y acceso de América Latina. Resultado: Se desarrollan requerimientos mínimos para la implementación de un pro- grama. Discusión: El número de programas en la región es escaso y depende más de esfuerzos individuales que de políticas generales de salud. Consideramos que estos lineamien- tos pueden servir de apoyo para el desarrollo de más programas en la región y de for- ma más homogénea.

Introduction: Lung cancer (LC) is a disease with a great impact worldwide in the number of deaths and health costs. The high incidence and mortality of this disease associated with late diagnosis and the improved prognosis with early detection determine that it is a pathology that can benefit from early detection. Low radiation dose tomography (LDCT) demonstrated a method that can be performed periodically to a group of people at high risk of developing CP and thus reduce mortality from this disease. However, this benefit is such when it is developed under an organized program with multidisciplinary participation specialized in lung cancer. Methods: It is proposed to determine basic guidelines for the development of early de- tection of lung cancer in Latin America so that it can be carried out uniformly, with the lowest risk and the maximum expected benefit. The main publications referring to this topic were analyzed, considering the diversity of care and access in Latin America. Result: Minimum requirements are developed for the implementation of a program. Discussion: The number of programs in the region is small and depends more on individual efforts than on general health policies. We consider that these guidelines can serve as support for the development of more programs in the region and in a more ho- mogeneous way.

Effects of the lesion size on clinically significant prostate cancer detection rates in PI-RADS category 3-5 lesions.

INTRODUCTION: Prostate cancer (PCa) ranks second among prevalent cancers in men, necessitating effective screening tools such as multiparametric magnetic resonance imaging (mpMRI) with the prostate imaging reporting and data system (PI-RADS) classification. This study explores the impact of lesion volume on clinically significant prostate cancer (csPCa) detection rates in PI-RADS 3-5 lesions, aiming to contribute insights into the underexplored relationship between lesion size and csPCa detection. MATERIALS AND METHODS: A retrospective analysis was conducted on data from 754 patients undergoing mpMRI-guided transrectal ultrasound (TRUS) prostate biopsy between January 2016 and 2023. Patients with PI-RADS 3, 4, and 5 lesions were included. Lesion size and PI-RADS categories were assessed through mpMRI, followed by MR fusion biopsy. RESULTS: Of the patients, 33.7%, 52.3%, and 14.1% had PI-RADS 3, 4, and 5 lesions, respectively. Lesion sizes correlated significantly with csPCa detection in PI-RADS 4 and 5 categories. For PI-RADS 3 lesions, no significant differences in csPCa rates were observed based on lesion size. However, in PI-RADS 4 and 5 groups, larger lesions showed higher csPCa rates. CONCLUSION: This study suggests that subgroup categorizations based on lesion volume could predict clinically significant PCa with high accuracy, potentially reducing unnecessary biopsies and associated overtreatment. Future research should further explore the relationship between lesion size and csPCa, clarifying discussions regarding the inclusion of systematic biopsies in diagnostic protocols.

A new promising indicator in prostate cancer screening: Prostate-specific antigen fluctuation rate.

OBJECTIVES: To evaluate whether PSA fluctuation can be used to predict the risk of prostate cancer. MATERIALS AND METHODS: The study included 1244 patients who underwent prostate biopsy at Kartal Dr. Lutfi Kirdar City Hospital between 2013 and 2021 (848 in non-cancer; 396 in cancer). The patient's age, last two PSA values (PSA1 and PSA2) within three months before the biopsy, the duration between two PSAs (days), prostate size (g) and PSA density (PSAD) were all recorded. PSA fluctuation rate (PSAfr) was defined as the change rate between two PSA values. RESULTS: PSAfr was significantly higher in the non-cancer group than in the prostate cancer group (15.2% (20.5) and 9.6% (14.4), P=.019). A Simple linear regression was used to examine the relationship between PSAfr and other factors such as age, PSA, PSAD, and prostate volume, but it was shown that these had no effect on PSA fluctuations. ROC analysis revealed a relatively low Area Under the Curve (AUC) for PSAfr (AUC, 0.584 (0.515-0.653)). However, the cut-off value of 12.35% was found to be significant, with a sensitivity of 58% and a specificity of 59% (P:.019, 95%CI). The odds ratio, adjusted for age, PSAD, and PSA2, was calculated as 0.545 (0.33-0.89) using logistic regression analysis to show the relationship between prostate cancer and PSAfr. As a result, those with high PSAfr were found to be 1.83 times less likely to be diagnosed with prostate cancer than those with low fluctuations. CONCLUSION: PSAfr could be used in nomograms to predict prostate cancer risk and reduce the number of unnecessary biopsies.

Dietitian-nutritionist incorporation in a university hospital: position statement of the Commission on Nutrition, Hospital Universitario La Paz.

Introduction: The present document has the objective of justifying the incorporation of a dietician/nutritionist to the multidisciplinary teams of specialized care that provide education, food anamnesis, nutritional recommendations, treatment and follow up of those patients in risk of malnutrition in Madrid. The appropriate nutritional status of hospitalized patients bears a close relationship with the existence of dieticians at hospitals. Dieticians use nutrition therapy as a cost-effective means to achieve significant health benefits by preventing or altering the course of diabetes, obesity, hypertension, lipid metabolism disorders, heart failure, osteoporosis, celiac disease, and chronic kidney disease, among other diseases.

Introducción: El presente documento tiene como objetivo plantear y justificar la incorporación del dietista-nutricionista en los equipos multidisciplinares de atención integrada en la educación, el tratamiento y el seguimiento de aquellos pacientes con patologías que cursen con alteraciones del estado nutricional, tanto en su defecto como en su exceso, en el área sanitaria de la Comunidad Autónoma de Madrid. El estado nutricional de los pacientes hospitalizados se beneficiará de la incorporación del dietista-nutricionista al equipo multidisciplinar que, actualmente, se ocupa de la atención de estos. El manejo de la terapia nutricional por dietistas-nutricionistas ha demostrado ser costo-efectiva, habida cuenta de la repercusión sanitaria que tiene el estado nutricional en la evolución clínica y prevención de enfermedades como la diabetes, los trastornos de la conducta alimentaria, la obesidad, el cáncer, la insuficiencia cardiaca, la osteoporosis, la enfermedad celiaca y la enfermedad renal crónica, entre otras.

Cancer screening in people with HIV: Implementation in clinical practice and barriers perceived by medical specialists in Spain.

OBJECTIVE: To assess the degree of implementation of cancer screening recommendations in people living with HIV (PLHIV) in Spain. METHODS: A self-administered questionnaire was designed on the strategies used for early detection of the main types of cancer in PLHIV. The survey was distributed electronically to HIV physicians participating in the Spanish CoRIS cohort. RESULTS: 106 questionnaires were received from 12 different Spanish Autonomous Communities, with an overall response rate among those who accessed the questionnaire of 60.2%. The majority responded that they followed the CPGs recommendations for the early detection of liver (94.3%), cervical (93.2%) and breast (85.8%) cancers. In colorectal and anal cancer, the proportion was 68.9% and 63.2%, and in prostate and lung cancer of 46.2% and 19.8%, respectively. In hospitals with a greater number of beds, a tendency to perform more cancer screening and greater participation of the Infectious Diseases/HIV Services in the screening programmes was observed. Significant differences were observed in the frequency of colorectal and anal cancer screening among the different Autonomous Communities. The most frequent reasons for not performing screening were the scarcity of material and/or human resources and not being aware of what is recommended in the CPGs. CONCLUSIONS: There are barriers and opportunities to expand cancer screening programmes in PLHIV, especially in colorectal, anal and lung cancers. It is necessary to allocate resources for the early detection of cancer in PLHIV, but also to disseminate CPGs screening recommendations among medical specialists.

NUTRISCORE as a tool to predict greater weight loss and longer hospital stay in cancer patients.

Introduction: Introduction: malnutrition in cancer patients is quite common and can cause various types of harm such as reduced tolerance to therapeutic measures and increased hospital stay. Identification of nutritional risk for these patients may minimize these problems. NUTRISCORE screening has been associated with Global Subjective Assessment Produced by Patient (ASG-PPP) screening, which is considered as the gold standard in cancer patients. No study has evaluated its predictive value in relation to weight loss and length of hospital stay in Brazil. Thus, the present study aims to analyze the NUTRISCORE tool, translated and adapted to the Brazilian population, as a predictor of longer hospital stays, as well as greater hospital weight loss. Methods: first, the NUTRISCORE tool was translated and adapted to the Brazilian population and subsequently applied to patients of both sexes, over 20 years old, admitted to the Cancer Hospital of Pernambuco. The patients were screened and classified as nutritionally "at risk" or "not at risk", their weight was measured at the time of admission and time of discharge from the hospital, and they were followed up throughout their stay to assess their weight loss and length of hospital stay. Results: one hundred and one patients participated in the study, with a higher prevalence of adults and males. The NUTRISCORE showed that patients "at nutritional risk" had a higher risk of greater weight loss (p = 0.001) and longer hospital stay (p = 0.007). Conclusion: NUTRISCORE proved to be a good predictor of longer hospital stay and greater weight loss among hospitalized patients.

Introducción: Introducción: la desnutrición en pacientes con cáncer es bastante común y puede causar diversos daños, como la reducción de la tolerancia a las medidas terapéuticas y el aumento de la estancia hospitalaria. Por tanto, es fundamental identificar a los pacientes con riesgo nutricional para minimizar estos problemas. El tamizaje NUTRISCORE tiene una buena asociación con el tamizaje Global Subjective Assessment Produced by Patient (ASG-PPP), que se considera el estándar de oro en pacientes con cáncer, y ningún estudio evaluó su valor predictivo en relación con la pérdida de peso y la duración de la estancia hospitalaria en Brasil. Así, el presente estudio tiene como objetivo analizar la herramienta NUTRISCORE, traducida y adaptada a la población brasileña, como predictor de estancias hospitalarias más prolongadas, así como de mayor pérdida de peso hospitalario. Métodos: primero, la herramienta NUTRISCORE fue traducida y adaptada a la población brasileña y posteriormente aplicada a pacientes de ambos sexos, mayores de 20 años, internados en el Hospital del Cáncer de Pernambuco. Los pacientes fueron tamizados y clasificados como nutricionalmente "de riesgo" o "sin riesgo", se midió su peso al momento del ingreso y el alta del hospital y se les hizo seguimiento durante toda su estadía para evaluar su pérdida de peso y el tiempo de estancia hospitalaria. Resultados: participaron en el estudio 101 pacientes, con mayor prevalencia de adultos y de sexo masculino. El NUTRISCORE mostró que los pacientes "en riesgo nutricional" tenían mayor riesgo de mayor pérdida de peso (p = 0,001) y mayor estancia hospitalaria (p = 0,007). Conclusión: NUTRISCORE demostró ser un buen predictor de mayor estancia hospitalaria y mayor pérdida de peso entre los pacientes hospitalizados.

Influence of social support and stressful life events on adherence to colorectal cancer screening using faecal occult blood test in Spanish medium risk population.

INTRODUCTION: Colorectal cancer (CRC) is the second cause of cancer-related deaths worldwide. Five-year survival rate in Spain is 57%. The most important prognostic factor is the stage of the tumor at the diagnosis. CRC can be early diagnosed, but the adherence to screening programs is low (<50%). This study aims to ascertain the influence of social support and stressful life events on the adherence to the population screening of CRC with fecal occult blood test in Spanish average risk population. METHODS: Multicenter case-control study. We conducted a simple random sampling among individuals invited to participate in the colorectal cancer screening program. We analyzed epidemiological and social variables associated with lifestyle and behavioral factors. We performed a descriptive and a bivariant analyses and a logistic regression analysis. RESULTS: Four hundred and eight patients (237 cases and 171 controls) were included. Multivariant analyses showed independent association between higher adherence to the screening program and older age (OR: 1.06; 95% CI: 1.01-1.10), stable partner (OR: 1.77, 95% CI: 1.08-2.89) and wide social network (OR: 1.68; 95% CI: 1.07-2.66). Otherwise, lower adherence was associated to perceiving barriers to participate in the program (OR: 0.92; 95% CI: 0.88-0.96). We find a statistically significant association between lower adherence and high impact stressful life events in the bivariant analyses, and the tendency was maintained (OR: 0.63, 95% CI: 0.37-1.08) in the multivariant. CONCLUSION: Social variables decisively influence the adherence to colorectal cancer screening. The implementation of social interventions that improve social support, reduce impact of stressful life events and the design of screening programs that decrease the perceived barriers, will contribute to increase the participation on these programs. Secondary, the colorectal cancer diagnosis will be made in early-stages with the consequent mortality reduction.

[Screening for heart disease in kids and adolescents (Prevencar Program)]. / Screening de cardiopatías en niños y adolescentes (Prevencar Program).

OBJECTIVE: The objective was to develop a screening for heart disease detection in primary care, to identify pathological electrocardiographic changes and underlying heart disease in adolescents. DESIGN: The study was carried out for one year using multistage sampling. SITE: Primary care centers in a health area that had digital ECG equipment (12 centers) were selected. PARTICIPANTS: Initially, 718 (16.6%) 14-year-old adolescents were recruited and those with a previous diagnosis of heart disease were excluded. INTERVENTIONS: Screening consisted of including a health questionnaire in the mandatory 14-year-old check-up. MAIN MEASUREMENTS: Screening included a questionnaire, cardiac auscultation, ECG and echocardiography. Abnormality criteria were established to refer for a second evaluation by a cardiologist. RESULTS: Finally, the sample was made up of 698 adolescents, with a mean age of 13.7±0.5 years, and 354 (50.7%) were boys. A total of 149 (21.3%) were selected for a second review by cardiology: 88 (12.6%) due to a positive questionnaire, 11 (2.2%) due to abnormal cardiac auscultation, and 66 (9.5%) due to ECG findings. Adolescents with evidence of heart disease were 24 (3.4%). Of these, 14 (2.0%) had suggestive alterations and follow-up was recommended, 6 (0.9%) had a definitive diagnosis of heart disease, and 4 (0.6%) had other pathological findings related to the cardiovascular system. CONCLUSIONS: The screening allowed us to identify 1% of adolescents with heart disease and another 2% will remain in follow-up. The ECG detected more pathological cases than the questionnaire.

Participatory design of Short Message Service (SMS) text message to promote mammography among women in Santa Fe, Argentina / Desenho participativo de uma mensagem de texto de Serviço de Mensagens Curta (SMS) para promover a mamografia entre as mulheres em Santa Fé, Argentina / Diseño participativo de un mensaje de texto de Servicio de Mensajes Cortos (SMS) para promover la mamografía entre las mujeres de Santa Fe, Argentina

We describe results of the design process of the content of the SMS messages to promote mammography. We conducted four online focus groups with women aged 50 or more (n=14). We used participatory techniques to debate the advantages and disadvantages of different options for the five structural elements of the SMS message. Our results showed that women argued that the opening line should provide clear information about the topic of the SMS message. SMS messages should include the woman's name, information about who and how to get a mammogram and use a health institution as a sender. The closing line should encourage women to get a mammogram. A personalized SMS could be a good way of inviting women to perform the mammography. The content must be carefully designed to provide clear information about how to schedule an appointment.(AU)

Descrevemos os resultados do processo de concepção do conteúdo das mensagens SMS para promover a mamografia. Quatro grupos focais on-line foram conduzidos com mulheres com cinquenta anos ou mais (n=14). Técnicas participativas foram usadas para discutir opções para cinco elementos estruturantes da mensagem SMS. As mulheres indicaram que a linha de abertura deveria fornecer informações claras sobre o assunto da mensagem SMS. As mensagens SMS devem incluir o nome da mulher, informações sobre quem e como obter uma mamografia e usar uma instituição de saúde como remetente. A sentença final deve encorajar as mulheres a fazer uma mamografia. Um SMS personalizado poderia ser uma boa maneira de convidar mulheres, embora seu conteúdo deva ser cuidadosamente projetado para fornecer informações claras sobre como agendar uma mamografia.(AU)

Resumen Introducción : Es fundamental poner en práctica ac ciones preventivas y de diagnóstico poblacional precoz para detectar a las personas en riesgo de desarrollar Diabetes tipo 2 (DT2). El objetivo del trabajo fue evaluar el desempeño del score FINDRISC como método de cri bado para detectar prediabetes y DT2 sin diagnostico en trabajadores municipales. Métodos : Estudio epidemiológico, descriptivo de corte transversal desde 10/21 al 3/22. Ingresaron voluntarios mayores a 18 años sin diagnóstico previo de DT2, se excluyó quienes padecían una enfermedad aguda, emba razadas o que realizaban tratamiento con medicamentos que modifiquen la glucemia. Los participantes comple taron el FINDRISC y realizaron una Prueba Oral de Tole rancia a la Glucosa (POTG). El desempeño se determinó mediante el cálculo de la sensibilidad (S), especificidad (E), y el área bajo la curva (AUC-ROC). Se utilizó un índice de Youden para definir el punto de corte óptimo. Resultados : Ingresaron 148 personas, entre 18-67 años, con media de edad 42.9 ± 11.8 años, el 68.9% de sexo masculino. La frecuencia de DT2 sin diagnóstico fue del 3.3% (n = 5) y de prediabetes del 12.2% (n = 18). El promedio de puntos de FINDRISC fue de 10.0 ± 4.8. El punto de corte optimo fue ≥ 13 (S = 65.2% y E = 74.4%) y el AUC-ROC 0.76 (IC95%: 0.66-0.86). Conclusión : El FINDRISC demostró ser un método eficaz para identificar personas con DT2 y prediabetes con punto de corte 13 en la población, lugar y periodo de estudio.

Abstract Introduction : It is fundamental to put into practice preventive and early population diagnosis actions to detect people at risk for developing Type 2 diabetes (T2D). The aim of this study was to evaluate the FINDRISC score performance as screening method to detect prediabetes and unknown T2D in municipal workers. Methods : descriptive epidemiological and cross-sectional study from 10/21 to 03/22. People suffering from a severe illness, pregnant or were already receiv ing drugs that modify blood glucose, were excluded. Participants completed the FINDRISC and performed an oral glucose tolerance test (OGTT). The performance of the FINDRISC was determined by calculating sensitiv ity, specificity, and area under the curve (AUC-ROC). The Youden's J statistic index was used to define the optimal cutoff point. Results : 148 subjects between the ages of 18-65 were admitted, with a mean age of 42,9 ± 11,8, the 69% being males. The frequency of unknown T2D was of 3.3% (n = 5) and frequency of prediabetes was of 12.2% (n = 18). The mean of FINDRISC score was of 10.0 ± 4.8. The optimal cutoff point was ≥ 13 (sensitiv ity = 65.2%, Specificity = 74.4%) and the AUC-ROC 0.76 (IC95%: 0.66-0.86). Conclusion : The FINDRISC proved to be an effective method for identifying people with undiagnosed T2D and prediabetes with a cut-off point of 13 in the popula tion, place, and study period.

Corrected sinus node recovery time as a screening test in patients with typical atrial flutter post-ablation to predict pacemaker implantation / Tiempo de recuperación del nodo sinusal corregido como prueba de tamizaje en pacientes con aleteo atrial típico postablación para predecir la implantación de marcapasos

Abstract Objective: The objective of the study was to establish the prognostic value of CSNRT regarding the necessity for pacemaker implantation in patients with atrial flutter (AFL) post-ablation. Methods: This prospective cohort study, conducted at the National Institute of Cardiology "Ignacio Chavez" in Mexico City, assessed patients who had undergone ablation procedures to correct AFL, posterior to which an autonomic blockade was performed, and CSNRT was measured. Results: The sample for this investigation was 40 patients. These were subdivided into two study groups depending on their requirement of pacemaker implant post-ablation (Pacemaker P, No Pacemaker NP). Sinus node (SN) dysfunction was diagnosed in 13 (32.5%) of the 40 participants, 10 (71.43%) of which required a pacemaker implant, while only 4 participants (28.57%) with normal SN function required pacemakers. Ten out of the 14 patients (71.43%) who required a pacemaker had an elevated CSNRT > 500 ms (p ≤ 0.01). Post-ablation CSNRT mean was 383.54 ms ± 67.96 ms in the NP group versus 1972.57 ms ± 3423.56 ms in the P group. Furthermore, SN pause in the P group had a mean of 1.86 s ± 0.96 s versus the NP group with 1.196 s ± 0.52 s. Conclusion: CSNRT has the potential to be a quantitative prognostic tool for the assessment of future pacemaker implants in patients with AFL post-ablation. This could aid in the timely diagnosis of sinus node dysfunction, which could, in the long run, result in the reduction of cardiac functional capacity loss due to cardiac remodeling.

Resumen Objetivo: Establecer el valor pronóstico del TRNSC basado en la necesidad de marcapasos en pacientes diagnosticados con aleteo atrial, pos-ablación. Métodos: Este cohorte prospectivo, realizado en el Instituto Nacional de Cardiología "Ignacio Chávez" en la Ciudad de México, evaluó pacientes sometidos a ablación para corregir el aleteo atrial; se midió el TRNSC post bloqueo autonómico. Resultados: La muestra de 40 pacientes se subdividió en 2 grupos según su requerimiento de marcapasos posterior a la ablación (P y NP). Se diagnosticó disfunción del nodo sinusal en 13 participantes (32.5%), de los cuales 10 (71.43%) requirieron marcapasos en comparación a 4 (28.57%) con función normal. En el grupo P la pausa del nodo sinusal post-ablación tuvo una media de 1.86 ± 0.96 s versus el grupo NP con 1.196 ± 0.52 s. En relación con el TRNSC, el grupo NP tuvo una media de 383.54 ± 67.96 ms vs. 1972.57 ± 3423.56 ms en el grupo P. 10 pacientes (25%) obtuvieron un TRNSC > 500 ms, de los cuales 100% requirieron marcapasos; de los 14 pacientes que requirieron marcapasos 10 (71.43%) tenían un TRNSC elevado (p ≤ 0.01). Conclusiones: El TRNSC tiene el potencial de ser una herramienta de pronóstico cuantitativo para la necesidad de futuros implantes de marcapasos en pacientes con disfunción del nodo sinusal, resultado de aleteo atrial pos-ablación. Esto podría ayudar a diagnosticar más temprano una disfunción del nodo sinusal, resultando en la reducción de la pérdida a largo plazo de la función cardíaca como efecto de la remodelación.

Errores innatos del metabolismo. avances en el diagnostico y terapeutica / Inborn errors of metabolism. Advances in diagnosis and therapeutic

Resumen Las novedades en el campo de los errores innatos del metabolismo (EIM) son espectaculares. Se han descrito nuevos EIM, se conoce mejor sus bases fisiopatológicas y las implicaciones para el organismo. Con la llegada de las nuevas técnicas de metabolómica, lípidomica y genómica se han multiplicado los avances en el diag nóstico y permiten explorar nuevas opciones terapéu ticas. Se ha establecido una nueva clasificación de los EIM en base a los más de 1.450 EIM identificados. Está irrumpiendo una nueva especialidad, que es la medici na metabólica. El cribado neonatal se estáempezando a universalizar y nos permite hoy en día, con tándem masas, el diagnóstico de más de 20 enfermedades me tabólicas del período neonatal que tienen opciones de tratamiento. Se están creando unidades de EIM para adultos para seguir niños con EIM que sobreviven a la enfermedad y con cada vez mejor calidad de vida y se diagnostican EIM que debutan en la adolescencia o laedad adulta. Aparecen las terapias personalizadas y las guías de práctica clínica para muchos EIM. Finalmente están emergiendo cada vez nuevas opciones terapéuticas que permiten una mayor supervivencia y mejor calidad de vida. La terapia génica convencional ya se está aplicando en algunos EIM.Sin embargo, las estrategias de edición de genes con terapias de ARN pueden permitir corregir la mutación genética mini mizando los problemas asociados con la terapia génica de compensación convencional.

Abstract The advances in the field of inborn errors of metabo lism (IEM) are spectacular. New IEM have been described, their pathophysiological bases and implications for the organism are better known. With the advent of new metabolomics, lipidomics and genomics techniques, advances in diagnosis have multiplied and allow new therapeutic options to be explored. A new IEM classi fication has been established based on the more than 1.450 IEM identified. A new specialty is emerging, which is metabolic medicine. Neonatal screening is becom ing universal and allows us today, with tandem mass, to diagnose more than 20 metabolic diseases of the neonatal period, with treatment options. IEM units for adults are being created to follow-up children with IEM who survive the disease and with an increasingly better quality of life, and some IEM that start in adolescence or adulthood are diagnosed. Personalized therapies and clinical practice guidelines appear for any IEM. Finally, new therapeutic options are emerging day to day that allow a longer survival and better quality of life. Con ventional gene therapy is already being applied in some IEM. However, gene editing strategies with RNA thera pies may allow the correction of the genetic mutation, minimizing the problems associated with conventional compensation gene therapy.

A look ahead to promote the early detection of lung cancer: technical and cost implications of a confirmed diagnosis before surgery.

OBJECTIVE: To compare the costs and length of hospital stay among patients with a confirmed diagnosis of lung cancer (LC) prior to surgery versus those without confirmation. METHODS: This retrospective, single-center study was conducted in patients who underwent a surgical procedure for LC, with or without a pathologically confirmed LC diagnosis prior to surgery, between March 2017 and December 2019. The main outcomes were costs and length of hospital stay (LOS). RESULTS: Among the 269 patients who underwent surgery for lung cancer between March 2017 and December 2019, 203 (75.5%) patients underwent surgery due to a histopathological diagnosis, and 66 (24.5%) because of a Multidisciplinary Cancer Committee indication. The unadjusted mean cost was significantly lower in Group II (patients with surgery based on Multidisciplinary Cancer Committee criteria) (Є2,581.80 ± Є1,002.50) than in Group I (patients with histopathological diagnosis) (Є4,244.60 ± Є2,008.80), P < 0.0001. Once adjusted for covariables, there was a mean difference of -Є1,437.20 in the costs of Group II, P < 0.0001. Unadjusted mean hospital stay was significantly longer in Group I (5.6 days) than in Group II (3.5 days). CONCLUSIONS: The results suggest that indicating surgical resection of lung cancer based on Multidisciplinary Cancer Committee criteria, rather than performing CT-guided percutaneous lung biopsy, may result in a significant decrease in cost and length of hospital stay.

Resultados: Acorde con el resultado de la prueba rápida prueba rápida EPD.3PO, el 64% de los pacientes contestaron afirmativamente a la pregunta ¿si se ha sentido triste o desesperanzado? 38% de los encuestados respondieron positivamente a la pregunta ¿ha presentado pérdida de interés en realizar actividades diarias?, y el 17% de los pacientes respondió positivamente a la tercera pregunta ¿ha pensado en dejar de vivir? Se considera positiva la prueba ante cualquier respuesta positiva. Conclusiones: Los pacientes con insuficiencia cardiaca presentan síntomas depresivos, detectados por prueba de Tamizaje rápido (EPD.3PO), la cual se puede considerar una prueba eficiente y de sensibilidad en esta población.

Abstract Introduction: The present study identified depressive symptoms in patients with heart failure (HF), using the EPD.3PO rapid test. Method: A cross sectional descriptive, non-probabilistic observational study. One hundred patients, over 18 years old, with stable heart failure, without depression, where recruited for this study in a clinic in Florencia Caqueta, Colombia. Previous signature a voluntary consent demographic data were taken and the EPD 3PO rapid test was applied to each patient in order to find depressive symptoms in these patients. Results: From the EPD 3PO rapid test 64% of patients answered positively to the question: Have you felt sad or hopeless? 38% answered affirmatively to the question Have you presented a loss of interest in carrying out daily activities? And 17% to, have you thought about giving up living? Had a positive answer, so the test was positive for majority of patients who was applied. Conclusions: Patients with heart failure should have undetected depressive symptos so the EPD 3PO rapid test could be an important screening tool the do an early detection of depression on this type o patients.
