Trasplante ortóptico de hígado en un paciente con una prueba positiva de SARS-CoV-2 y sus complicaciones posoperatorias. Reporte de caso / Orthoptic liver transplantation in a patient with a positive SARS-CoV-2 test and its postoperative complications. Case report

Resumen Objetivo: describir un caso de trasplante hepático en un paciente con resultado positivo en la prueba del coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) con éxito en el postrasplante temprano, pero que desarrolló complicaciones asociadas a la inmunosupresión y trombosis portal sin una trombofilia identificada en un centro de alta complejidad de un país latinoamericano. Descripción del caso: paciente de 48 años con diagnóstico de cirrosis hepática secundaria a esteatohepatitis no alcohólica (NASH) complicada por varios episodios de ascitis portal hipertensiva y encefalopatía hepática, ingresada para trasplante hepático ortóptico. En los exámenes iniciales tuvo una prueba positiva para SARS-CoV-2 y era asintomático respiratorio. El trasplante se realizó con éxito luego de la autorización del comité de infección. Después del primer mes posoperatorio presentó diarrea, ascitis y daño renal agudo. Los niveles de tacrolimus en el reingreso fueron superiores a 10 ng/mL y hubo una mejoría clínica significativa con la suspensión del fármaco. Finalmente, el paciente requirió retrasplante por trombosis de la vena porta y de las venas suprahepáticas, aunque no se identificó la etiología. Conclusión: se describe uno de los primeros informes de trasplante de hígado en un paciente con recuperación reciente de COVID-19 y pruebas persistentemente positivas. En el postrasplante temprano hubo una buena respuesta; sin embargo, luego del primer mes presentó complicaciones relacionadas con la inmunosupresión. Este caso también plantea la posible asociación entre el SARS-CoV-2 y el desarrollo de trombosis en la circulación portal hepática.

Abstract Objective: To describe a case of liver transplantation in a patient with a positive result in the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) test with success in the early post-transplantation, but who developed complications associated with immunosuppression and portal vein thrombosis without thrombophilia identified at a tertiary referral center in a Latin American country. Case: A 48-year-old patient diagnosed with liver cirrhosis secondary to non-alcoholic steatohepatitis (NASH) complicated by several episodes of portal hypertension ascites and hepatic encephalopathy was admitted for orthoptic liver transplantation. On initial examinations, he had a positive test for SARS-CoV-2 and was asymptomatic in the respiratory tract. The transplant was carried out successfully after the authorization of the infection committee. After the first postoperative month, he presented with diarrhea, ascites, and acute kidney injury. Tacrolimus levels at readmission were more significant than 10 ng/mL, and there was a significant clinical improvement with drug discontinuation. Finally, the patient required re-transplantation due to thrombosis of the portal vein and suprahepatic veins, although the etiology was not identified. Conclusion: One of the first reports of liver transplantation in a patient with recent recovery from COVID-19 and persistently positive tests is described. In the early post-transplant, there was a good response; however, after the first month, he had complications related to immunosuppression. This case also posits the possible association between SARS-CoV-2 and the development of thrombosis in the hepatic portal circulation.

Evaluation of Women's Empowerment in a Community-Based Human Papillomavirus Self-Sampling Social Entrepreneurship Program (Hope Project) in Peru: A Mixed-Method Study.

Introduction: Understanding community women's relational and financial empowerment in social entrepreneurship could be the key to scaling up community-based human papillomavirus (HPV) self-sampling programs in low- and middle-income countries. The Hope Project, social entrepreneurship in Peru, trains women (Hope Ladies) to promote HPV self-sampling among other women in their communities. This study aims to evaluate the Hope Ladies' relational and financial empowerment after participating in the program. Materials and Methods: We evaluated the Hope Ladies' experiences of empowerment in social entrepreneurship using a parallel convergent mixed methods design. The Hope Ladies participated in semi-structured in-depth interviews (n = 20) and an eight-questions five-point Likert scale survey that evaluated their relational (n = 19)/financial (n = 17) empowerment. The interview and the survey questions were developed using three empowerment frameworks: Kabeer's conceptual framework, International Center for Research on Women's economic empowerment indicators, and the Relational Leadership Theory. Deductive content analysis was used to evaluate the interviews with pre-determined codes and categories of empowerment. Descriptive statistics were used to analyze the survey results. Qualitative and quantitative data were integrated through a cross-case comparison of emergent themes and corresponding survey responses during the results interpretation. Results: All Hope Ladies reported experiencing increased empowerment in social entrepreneurship. Interviews: The women reported challenges and improvement in three categories of empowerment: (1) resources (balancing between household and Hope Lady roles, recognition from the community as a resource, camaraderie with other Hope Ladies); (2) agency (increased knowledge about reproductive health, improved confidence to express themselves, and ability to speak out against male-dominant culture); and (3) achievement (increased economic assets, improved ability to make financial decisions, and widened social network and capital, and technology skills development). Survey: All (100%) agreed/totally agreed an increase in social contacts, increased unaccompanied visits to a healthcare provider (86%), improved confidence in discussing reproductive topics (100%), improved ability to make household decisions about money (57% pre-intervention vs. 92% post-intervention). Conclusions: The Hope Ladies reported improved relational and financial empowerment through participating in community-based social entrepreneurship. Future studies are needed to elucidate the relationship between empowerment and worker retention/performance to inform the scale-up of HPV self-sampling social entrepreneurship programs.

Multimorbilidad y síndromes geriátricos. Su efecto sobre la mortalidad en adultos mayores con sepsis / Multimorbidity and geriatric syndromes. Their effect on mortality in older adults with sepsis

Resumen Introducción: la sepsis se diagnostica en más de 60% de los adultos mayores (AM) en el mundo. Estos AM con frecuencia presentan multimorbilidad y alguno de los síndromes geriátricos, llevando a discapacidad física, cognitiva y psicosocial, lo cual produce altos costos para los sistemas de salud, resultando en un problema grave de salud pública. Objetivo: identificar el impacto de la multimorbilidad y los síndromes geriátricos en la morta lidad de AM hospitalizados por sepsis en una unidad geriátrica de agudos a 30 días de su ingreso. Material y métodos: estudio observacional, analítico de casos y controles anidado en una cohorte. Resultados: se analizaron 238 pacientes con edad media de 83.15±7.12 años, 52.1% fueron mujeres y el 99% tenían al menos una comorbilidad, la mortalidad a 30 días fue 34%. La infección urinaria fue la causa principal de hospitalización (42.9%), obteniendo un aislamiento microbio-lógico en 43.3% de los casos, siendo la Escherichia coli el agente causal más frecuente (46.6%). La regresión logística múltiple mostró que la enfermedad renal crónica (OR 2.1 IC 95% 1.1-4.8; p=0.037), el delirium (OR 3.1 IC 95% 1.6-5.8; p=0.001) y la discapacidad (índice de Barthel <60; OR 3.4 IC 95% 1.5-7.5; p=0.002) se asociaron de manera significativa con la mortalidad a 30 días desde el ingreso a la unidad geriátrica de agudos en paciente con sepsis. Conclusión: en los AM hospitalizados por sepsis, la multimorbilidad, la enfermedad re nal crónica y los síndromes geriátricos representados por delirium y discapacidad fueron los predictores de mortalidad a 30 días.

Abstract Introduction: sepsis is diagnosed in more than 60% of older adults (OAs) worldwide. These OAs often have multimorbidity and one of the geriatric syndromes, leading to physical, cognitive and psychosocial disability with consequently high healthcare costs, resulting in a serious public health problem. Objective: to determine the impact of multimorbidity and geriatric syndromes on the 30-day mortality rate of OAs hospitalized for sepsis in an acute geriatric unit Materials and methods: an observational, analytical, nested case-control study. Results: 238 patients with a mean age of 83.15±7.12 were analyzed; 52.1% were women and 99% had at least one comorbidity; the 30-day mortality was 34%. Urinary tract infection was the main cause of hospitalization (42.9%), with microbiological isolation achieved in 43.3% of cases and Escherichia coli being the most common causal agent (46.6%). Multiple logistic regression showed that chronic kidney disease (OR 2.1 95% CI 1.1-4.8; p=0.037), delirium (OR 3.1 95% CI 1.6-5.8; p=0.001) and disability (Barthel index <60; OR 3.4 95% CI 1.5-7.5; p=0.002) were significantly related to 30-day mortality in patients with sepsis admitted to an acute geriatric unit. Conclusion: in OAs hospitalized for sepsis, multimorbidity, chronic kidney disease and geriatric syndromes (represented by delirium and disability) were the predictors of 30-day mortality.

Aneurisma aórtico abdominal asociado a coagulación intravascular diseminada crónica: una complicación rara / Abdominal aortic aneurysm associated with chronic disseminated intravascular coagulation: a rare complication

Resumen La coagulación intravascular diseminada es un proceso sistémico caracterizado por la activación generalizada de la coagulación, que tiene el potencial de causar trombosis vascular, hemorragia y falla orgánica. En raras ocasiones, las anomalías vasculares, como el aneurisma aórtico abdominal, pueden desencadenar coagulación intravascular diseminada crónica. Los aneurismas aórticos grandes, su disección y su expansión son factores de riesgo. En estos casos predominan los síntomas subclínicos y la coagulopatía solo se identifica mediante pruebas de laboratorio. Existe evidencia limitada basada en la experiencia de series de casos de coagulación intravascular diseminada crónica como complicación en pacientes con aneurisma aórtico abdominal. Además, la duración y la respuesta terapéutica a la heparina no se conocen bien, principalmente en los pacientes con manejo conservador. Se considera un desafío diagnóstico y terapéutico debido a la baja frecuencia de presentación. A continuación, se describen las características clínicas y paraclínicas, así como el tratamiento, de un paciente con aneurisma aórtico abdominal asociado con coagulación intravascular diseminada crónica.

Abstract Disseminated intravascular coagulation is a systemic process characterized by the widespread activation of coagulation with the potential for causing vascular thrombosis, hemorrhage and organ failure. Rarely, vascular anomalies like abdominal aortic aneurysm can trigger chronic disseminated intravascular coagulation. Large aortic aneurysms, dissection and expansion are risk factors. In these cases, subclinical symptoms predominate and coagulopathy is only identified by laboratory tests. Nowadays there is limited evidence based on experience from case series of chronic disseminated intravascular coagulation as complication in patients with abdominal aortic aneurysm. Furthermore, duration and therapeutic response with heparin therapy are not well known, mainly in those patients with conservative management. It is considered a diagnostic and therapeutic challenge due to the low presentation frequency. The clinical characteristics, laboratory and treatment of a patient with abdominal aortic aneurysm associated with chronic disseminated intravascular coagulation are described below.

Can study of the ADRB3 gene help improve weight loss programs in obese individuals? / ¿Puede el estudio del gen ADRB3 ayudar a mejorar los programas de pérdida de peso en individuos obesos?

INTRODUCTION: Obesity is a chronic disease of multifactorial origin characterized by excess weight and excess fat accumulation, and whose etiology includes intrinsic (genetic, physiological, and metabolic) and extrinsic (social and cultural) factors. Fat accumulation is caused by a prolonged imbalance in the energy balance influenced, among other factors, by adaptive thermogenesis, which is triggered by cold environmental conditions, or by hypercaloric intake. Thermogenesis is regulated by the sympathetic nervous system and occurs in the muscle and brown adipose tissue. There are adrenergic receptors in brown adipose tissue, including the beta-3 adrenergic receptor (ADRB3), the main receptor for the regulation of thermogenesis. The presence in heterozygosis of an SNP-type polymorphism in the ADRB3 gene (Trp64Arg; rs4994) is associated with a lower lipolytic activity, a predisposition to obesity, and resistance to weight loss. The objective of this study was to analyze through a systematic review the weight loss program most appropriate for carriers. METHODS: A retrospective study of published papers on rs4994 polymorphism in the SNP and PubMed databases was conducted. RESULTS: Most published studies suggest the presence of obesity and resistance to weight loss in carriers, and report significant improvements in anthropometric parameters when patients receive fat-rich hypocaloric diets. CONCLUSIONS: Based on these conclusions, specific nutritional and physical exercise guidelines are proposed for individuals carrying the Trp64Arg allele.

Prevalence of urinary cotinine levels in children under 5 years of age during consultations for acute respiratory disease at the emergency department of the Universidad de La Sabana clinic.

BACKGROUND: Several environmental factors favour the occurrence of acute respiratory disease, which is the main reason for paediatric consultations in our country (Colombia). Tobacco smoke is considered a significant environmental pollutant with a great impact on health. The objective of this study is to estimate the prevalence of cotinine levels measured in urine, in children between 1 to 60 months of age who attended an emergency department with acute respiratory disease. METHODS: A cross-sectional study was conducted that included children between 1 and 60 months of age with acute respiratory disease who were admitted to the emergency department of the Universidad de La Sabana Clinic between April and July 2016. RESULTS: We included 268 patients and 36% were female. Of the total population examined, 33.96% showed positive results for urinary cotinine, of whom 97.8% had values between 10 and 100 ng/ml, which is considered positive for exposure to second-hand smoke. The principal pathology was recurrent wheezing in 43.96% of these cases. Regarding the presence of smokers at home, it is important to mention that in 54.95% of the children with positive urinary cotinine test was no related with smokers at home. And in 45.05% of positive urinary cotinine was evidence of smokers at home, being associated with the positive result P <  0.001 and smoking within the house P = 0.018; smoking when children were present did not have significant P = 0.105. The activities performed after smoking such as hand washing, change of clothes, eating, brushing teeth, did not influence the test result P = 0.627. CONCLUSIONS: A high prevalence of urinary cotinine was observed, which is associated with the presence of a smoker at home, and this relationship was independent of the activities performed by the smoker after smoking. In addition, a positive test for urinary cotinine was presented in some children without documented exposure to cigarette smoke inside the home, which may be explained by the presence of environmental cotinine. Therefore, it is necessary to perform educational interventions aimed at parents and caregivers who smoke.

American Thyroid Association Sonographic Risk and Afirma Gene Expression Classifier Alone and in Combination for the Diagnosis of Thyroid Nodules with Bethesda Category III Cytology.

Background: The Afirma gene expression classifier (GEC) has been used to aid in the diagnosis and management of thyroid nodules having Bethesda category III fine-needle aspiration cytologic diagnosis (B3 nodules). The American Thyroid Association sonographic risk stratification system for thyroid nodules (ATA-US) may stratify B3 nodules and aid in the decision to order a molecular test. The aim of this study was to assess the association between ATA-US and GEC as well as to determine their individual and combined diagnostic performances when applied to B3 nodules. Methods: A retrospective single-center study included B3 nodules that had undergone evaluation by GEC. Each ultrasound was reviewed by three radiologists, and nodules were classified using the 2015 ATA sonographic risk categories. Nodules were determined to be benign or malignant based on surgical pathology or minimum 11 months of follow-up. Positive predictive values (PPV) and negative predictive values (NPV) were calculated for GEC, ATA-US, and GEC across all ATA-US categories. Results: One hundred twenty-six B3 nodules with GEC results were included and deemed benign or malignant based on final pathology or follow-up. Prevalence of malignancy was 32%. The rate of malignancy was similar in the ATA-US high suspicion (HS) and intermediate suspicion (IS) categories at 42% and 38%, respectively; and lower in nodules with low suspicion sonography (LS) and very low suspicion sonography (VLS) at 23% and 11%, respectively. The PPV and NPV of ATA-US was calculated by designating HS or IS sonography as a "positive" test and the lower risk categories as "negative." ATA-US had a PPV of 40% and NPV of 79%. The GEC PPV was 40% and NPV was 83%. The PPV of GEC was 50% in nodules with HS or IS ATA-US and lower at 28% and 20%, respectively, in LS and VLS nodules. The NPV of GEC was 80% in HS, 77% in IS, 84% in LS, and 100% in VLS sonography categories. Conclusions: In B3 nodules, ATA-US and GEC have similar diagnostic performance. The PPV of GEC varies across ATA-US categories, while the NPV remains similar. These data support the need for future prospective studies.

Conclusions: A low frequency of survival was found, which was associated with potentially modifiable factors(AU)

Burden of genital warts in Peru: an observational study.

Genital warts (GW) are mucosal or skin lesions caused by sexual transmission of human papillomavirus (HPV). This study estimates the frequency of GW cases in physicians' clinics and physicians' usual practices of GW referral and diagnosis in Peru. Participants in this study were a convenience sample of 100 physicians in five specialties: primary care (17), gynecology (37), urology (10), dermatology (31), and infectious diseases (5). Physicians completed a survey and daily log of all patients aged 18-60 years seen over ten days in their offices located in Peru. The survey recorded GW referral patterns and the daily log recorded patient demographic information and GW diagnosis. Among 12,058 patients, the annual GW prevalence (95% confidence interval [CI]) was 2.28% (2.02-2.56) and cumulative incidence (95% CI) was 1.60% (1.38-1.84). Physicians reported that most GW patients were direct consult (73.5% of male and 67.9% of females) and physicians treated most GW patients themselves (73.4% of males and 76.7% of females). As reported, the most common reasons for referring were 'serious cases requiring more specialized treatment' (73.2% of male and 72.2% of female) and 'lack of resources to treat' (26.8% of male and 27.8% of female). We conclude that GW cases are commonly seen by physicians in Peru.

Epidemiology of Candidemia at a University Hospital in Colombia, 2008-2014 / Epidemiología de los casos de candidemia en un hospital universitario en Colombia, 2008-2014

Introducción: Candida spp. es una levadura comensal de la microbiota humana. Por características del hospedero, las infecciones del torrente sanguíneo pueden aparecer y causar una gran morbimortalidad. Métodos: Estudio restrospectivo transversal analítico de los cultivos positivos para Candida spp. entre 2008 y 2014 en un hospital universitario en Bogotá, Colombia. Se evaluaron las características clínicas y microbiológicas presentes previo a la toma de la primera muestra de sangre positiva y se determinaron asociaciones con infecciones por especies no C. albicans (NCA). Resultados: Se incluyeron 123 casos de candidemia. C. albicans fue la especie más aislada (42 %). Sin embargo, las especies NCA como grupo fueron observadas más frecuentemente. Más del 70 % de los casos presentaron manejo en la unidad de cuidado intensivo, con una mediana de estancia de 14 días previo a la primera muestra de sangre positiva. Se detectaron numerosas características médicas; sin embargo, ninguna estuvo asociada con candidemia por especies NCA. Se observó resistencia a por lo menos un antifúngico en el 29 % de los casos, aunque en una muestra reducida de pruebas de sensibilidad. Conclusiones: Nuestros resultados sustentan el viraje mundial hacia la candidemia por especies NCA; pero no encontramos asociaciones clínicas en este grupo. Debe dársele prioridad a la identificación de factores de riesgo y a la optimización de los puntajes de predicción, que permitan identificar pacientes en riesgo que se beneficien de terapia preventiva.

Introduction: Candida species are commensal yeasts of the human microbiota. However, due to several host's conditions, bloodstream infections may arise causing high morbimortality. Methods: Retrospective cross-sectional analytical study of positive blood cultures for Candida spp. between 2008'2014 at a university hospital in Bogotá. Colombia. We evaluated clinical and microbiological characteristics prior to the first positive blood sample was obtained and determined associations with non'C. albicans (NCA) species infections. Results: We included 123 candidemia cases. C. albicans was the most frequently isolated species (42%). However; NCA species as a group were observed more often. Over 70% of cases were managed at the ICU, with a median stay of 14 days. Several medical factors were frequently observed, however none appeared to be associated with NCA species candidemia. Resistance to at least one antifungal agent was observed in 29% of cases, although a reduced sample of susceptibility tests was available. Conclusions: Our results support a worldwide shift towards NCA candidemia. However, clinical features were not associated with NCA infections. The identification of risk factors and the improvement of prediction scores must be prioritized, in order to identify' patients at high risk who may benefit of pre-emptive therapy.

[Preferences and satisfaction towards a screening program with self-administered human papilloma virus detection tests]. / Preferencias y satisfacción hacia un programa de tamizaje con pruebas autoadministradas de detección del virus de papiloma humano.

Cross-sectional study describing preferences and satisfaction towards a cervical cancer screening program with selfadministered rapid tests for the detection of human papillomavirus (HPV). Of 2 090 users picked by the program in Ventanilla Callao - Peru, 97 were randomly selected to be surveyed. In addition, interviews were conducted with women leaders of the community, in charge of providing the evidence. 74.2% of the users felt, at least, satisfied with the program. 68% of women prefer to take the test, mainly by demanding less time. Of women who prefer to take the test at the Health Center, 90.3% do so for the safety of the test being done correctly. The inclusion of community leaders in the program allowed a good diffusion of the test and the steps to carry it out.

Anorexia and bulimia nervosa: virtual diffusion of the disease as a lifestyle / Anorexia y bulimia nerviosas: difusión virtual de la enfermedad como estilo de vida.

Introduction: Adolescence is a vulnerable period for the onset of eating disorders (ED) such as anorexia and bulimia nervosas. Body dissatisfaction, a precipitating factor for ED, leads adolescents to seek information on the Internet about diets. In this context, pro-Ana (proanorexia) and pro-Mia (probulimia) are on-line pages that promulgate highly harmful contents for health related to weight loss and ED. Objectives: The aim of this study was to analyze quantity, quality and social diffusion strategies used by pro-Ana and pro-Mia webpages. Methods: A web search was done in the Google Chrome browser, using the keywords "anorexia", "bulimia", "eating disorders", "Ana and Mia", "pro-Ana and pro-Mia", "anorexic nation", "obesity", "healthy lifestyles" and "healthy nutrition". The top 20 results for each search were selected and analyzed according to positioning rates (PageRank, PR). The quality of these resources was analyzed by a previously published questionnaire. Finally, a study of the diffusion in social networks like Facebook and Twitter was performed for pro-Ana and pro-Mia pages using SharedCount. Results: Searches for pro-Ana and pro-Mia reported more than a million entries. The pages were poorly positioned. Blog contents were the most shared between all the analyzed pages. Conclusions: pro-Ana and pro-Mia are resources with a clear intention to establish a contact with people with an eating disorder or who are at risk for developing one, in order to strengthen the communication through the blogosphere.

Introducción: la adolescencia es un periodo vulnerable para padecer trastornos de la conducta alimentaria (TCA) como la anorexia y la bulimia nerviosas. La insatisfacción corporal, uno de los factores precipitantes de los TCA, conduce a las adolescentes a la búsqueda de información sobre dietas en internet. En este contexto, las páginas pro-Ana (proanorexia) y pro-Mía (probulimia) difunden contenidos altamente perjudiciales para la salud relacionados con la pérdida de peso y los TCA.Objetivos: en el presente trabajo se analizan la cantidad, el posicionamiento, la calidad y la difusión de las páginas pro-Ana y pro-Mía. Métodos: se realizó una búsqueda de páginas web en el navegador Google Chrome con las palabras clave "anorexia", "bulimia", "trastornos de la conducta alimentaria (TCA)", "Ana y Mía", "pro-Ana y pro-Mía", "anorexic nation", "obesidad", "estilos de vida saludables" y "nutrición saludable". Se seleccionaron los 20 primeros resultados de cada búsqueda según los índices de posicionamiento de PageRank y se analizó la calidad de dichos recursos mediante un cuestionario. Para el estudio de la difusión de páginas pro-Ana y pro-Mía en redes sociales como Facebook y Twitter se utilizó el programa SharedCount. Resultados: pro-Ana y pro-Mía dieron más de un millón de entradas, siendo páginas mal posicionadas, de tipo blog en su mayoría, con mayor difusión en Facebook y Twitter comparadas con otras de mejor calidad. Conclusiones: pro-Ana y pro-Mía son recursos con una clara intencionalidad de contactar con personas que padecen un TCA o están en riesgo, con el fin de reforzar la comunicación entre ellas a través de la blogosfera.
