High Financial Hardship among Patients with Advanced Ovarian Cancer.

Ovarian cancer is considered the most fatal and costly gynecologic cancer. Although personalized therapies have improved ovarian cancer prognosis, they have resulted in increased financial toxicity concerns among this population. This study evaluated financial toxicity in patients with advanced ovarian cancer. Using secondary data from a study of barriers to palliative care, financial toxicity (FT) was measured through the Comprehensive Score for Financial Toxicity scale. Univariate and bivariate analyses were used to assess the relationship between selected demographic (i.e., age, race, ethnicity, education, place of birth, insurance type, yearly household income, employment status) and treatment-specific variables (i.e., years since diagnosis, surgery, chemotherapy, radiation, hormonal and targeted therapy) with clinically relevant financial toxicity. Characteristics were compared using Fisher's exact or chi squared tests. A total of 38 participants with advanced ovarian cancer were included in this study; 24% (n = 9) reported clinically significant FT. Income (p = .001), place of birth (p = .048) and employment status (p = .001) were related to FT. Study findings highlight that advanced ovarian cancer patients experience high FT, particularly those with low income, who are not able to work and were born outside the US. Further research using larger datasets and more representative samples is needed to inform intervention development and implementation.

Metronidazole for Prevention of Pelvic Cellulitis and Abscess after Laparoscopic Hysterectomy: A Triple-blinded, Randomized, Placebo-controlled Clinical Trial.

STUDY OBJECTIVE: To determine whether a postoperative 5-day treatment schedule with vaginal metronidazole added to conventional antibiotic prophylaxis with 2 g cefazolin modifies the risk of pelvic cellulitis (PC) and pelvic abscess (PA) after total laparoscopic hysterectomy (TLH). DESIGN: A randomized, controlled, triple-blind, multicenter clinical trial. SETTING: Two centers dedicated to minimally invasive gynecologic surgery in Colombia. PATIENTS: A total of 574 patients were taken to TLH because of benign diseases. INTERVENTION: Patients taken to TLH were divided into 2 groups (treatment group, cefazolin 2 g intravenous single dose before surgery + metronidazole vaginal ovules for 5 days postoperatively, control group: cefazolin 2 g intravenous single dose + placebo vaginal ovules for 5 days postoperatively). MEASUREMENTS AND MAIN RESULTS: The absolute frequency (AF) of PC and PA and their relationship with the presence of bacterial vaginosis (BV) were measured. There was no difference in AF of PC (AF, 2/285 [0.7%] vs 5/284 [1.7%] in the treatment and placebo groups, respectively; risk ratio, 1.75; 95% confidence interval, 0.54-5.65; p = .261), nor for PA (AF, 0/285 [0%] vs 2/289 [0.7%]; p = .159, in the treatment and placebo groups, respectively). The incidence of BV was higher in the metronidazole group than the placebo group (42.5% vs 33.4%, p = .026). CONCLUSION: The use of vaginal metronidazole ovules during the first 5 days in postoperative TLH added to conventional cefazolin prophylaxis does not prevent the development of PC or PA, regardless of the patient's diagnosis of BV.

Factors involved in time reduction between seizure relapses in patients with epilepsy attending emergency rooms in Medellín, Colombia.

BACKGROUND: Seizure relapses are the leading cause of admission to emergency rooms (ER) in people with epilepsy. OBJECTIVE: To analyze administrative and clinical factors associated with the duration between seizure relapses in people with epilepsy admitted to the Neurological Institute of Colombia (Medellin) between July 2018 and July 2019. MATERIALS AND METHODS: A retrospective follow-up study of 156 patients over 18 years old, diagnosed with epilepsy, and treated for over a year. The outcome variable was the time between seizure relapses, identified through the record of ER attendances. In addition, difficulties in the prescription filling process (delay, omission, or brand change) and clinical characteristics were analyzed as potential associated influence factors. The statistical analysis was performed using the Prentice, Williams & Peterson-Gap Time survival model for recurrent events. Finally, Adjusted Hazard Ratios (aHR) with 95% confidence intervals (95%CI) are also presented. RESULTS: One hundred fifty-six patients were analyzed. Their average age of diagnosis was 15.5 years (SD = 22.5), the median number of monthly seizures was 3 (SD = 9.3), and 50.6% were women. Moreover, difficulties in the prescription filling process were associated with a time reduction between seizure relapses (aHR = 2.61; 95%CI 1.49-4.57), showing a similar impact as having a history of three or four types of events (aHR = 2.96; 95%CI 1.23-7.12) and neuropsychiatric comorbidity (aHR = 1.89; 95%CI 1.04-3.54). CONCLUSION: Neuropsychiatric comorbidity, history of several types of events, and experiencing difficulties with prescription filling are associated with lower benefit from treatment to control seizure relapses.

Barbed Suture versus Conventional Suture for Vaginal Cuff Closure in Total Laparoscopic Hysterectomy: Randomized Controlled Clinical Trial.

STUDY OBJECTIVE: To determine the surgical time, suture time, presence of postoperative dyspareunia, and complications that occur after closing the vaginal cuff with a barbed suture compared with conventional suture. DESIGN: A randomized, controlled clinical trial (Canadian Task Force classification I). SETTING: Private gynecologic clinic in Medellin, Colombia. PATIENTS: One hundred fifty women who underwent total laparoscopic hysterectomy for benign pathology. INTERVENTIONS: The patients underwent total laparoscopic hysterectomy with intracorporeal closure of the vaginal cuff and were randomized to 2 groups, 1 using a barbed suture (V-Loc 90; Medtronic/Covidien, New Haven, CT) and 1 using polyglactin 910 (coated Vicryl suture; Ethicon/Johnson & Johnson, New Brunswick, NJ). MEASUREMENTS AND MAIN RESULTS: The total operative time, closing time of the vaginal vault, presence of complications in the cuff, and incidence of postoperative dyspareunia were recorded. The patients were evaluated at a postoperative office visit 2 weeks after the procedure and by telephone interview at 24 weeks. Seventy-five patients were included in the barbed suture group and 75 patients in the polyglactin 910 group. The average time to complete the suture of the vaginal cuff was 12.01 minutes (± 5.37 standard deviation) for the barbed suture group versus 13.49 minutes (± 6.48) in the polyglactin 910 group (95% confidence interval, -.44 to 3.4; p = .130). Blood loss was 31.56 ± 22.93 mL in the barbed suture group versus 30.82 ± 21.75 mL in the polyglactin 910 group (95% confidence interval, -7.95 to 6.47; p = .840). The frequency of postoperative events such as hematoma, cellulitis, cuff dehiscence, fever, emergency consultation, and hospitalization was not statistically significant between groups. No statistically significant difference was found regarding deep dyspareunia at 24 postoperative weeks. CONCLUSION: No differences were found in surgical time or frequency of adverse events when comparing patients after vaginal cuff closure with barbed suture versus polyglactin 910.

[Perceived work self-efficacy, and characteristics of return to work in women survivors of breast cancer at two reference centers in Colombia]. / Autoeficacia laboral percibida, y características del retorno al trabajo en mujeres supervivientes de cáncer de mama en Colombia.

OBJECTIVE: Return to work and permanence in employment of women who survive breast cancer are topics that become important as incidence and survival rates increase. Self-efficacy as a modifiable element is of special interest in this process. The objective of this study is to measure the level of self-efficacy in female breast cancer survivors, according to sociodemographic, work and treatment characteristics and their relationship with return to work. METHODS: This was a cross-sectional study, based on a survey of breast cancer patients about their demographic and work characteristics, the return to work process, permanence in the same job and the level of work self-efficacy. Differences in the level of self-efficacy with respect to characteristics were evaluated using bivariate analyses and hypothesis statistical testing. A value of p<0.05 was considered statistically significant. RESULTS: One hundred and twenty-four women were included, 87.9% had returned to work, the majority (56.4%) between one and six months after treatment, 67.7% remained in the same job. Higher levels of work self-efficacy were related to a higher probability of returning to work and staying there, and a shorter time to return to work; these differences were statistically significant. CONCLUSION: Occupational health and risk prevention services must consider and strengthen work self-efficacy and organizational support in breast cancer survivors to achieve a successful return to work.

OBJETIVO: El objetivo de este estudio es analizar el nivel de autoeficacia en mujeres supervivientes de cáncer de mama, según las características sociodemográficas, laborales y de tratamiento y su relación con la reincorporación laboral. Métodos: Estudio transversal, basado en una encuesta a pacientes de cáncer de mama de dos centros oncológicos sobre sus características demográficas, laborales, el proceso de retorno al trabajo, la permanencia en el mismo empleo y el nivel de autoeficacia laboral. Se evaluaron las diferencias en el nivel de autoeficacia con respecto a las características mediante análisis bivariado y pruebas estadísticas de contraste de hipótesis. Un valor de p<0.05 se consideró estadísticamente significativo. RESULTADOS: Se incluyeron 124 mujeres, de las cuales 87,9% habían retornado al trabajo, la mayoría (56,4%) entre uno y seis meses después del tratamiento, y el 67,7% permanecían en el mismo empleo. Los niveles superiores de autoeficacia laboral se relacionaron con una mayor probabilidad de retorno al trabajo y permanencia en el mismo, y menor tiempo de reincorporación, siendo estas diferencias estadísticamente significativas. Conclusión: La autoeficacia laboral y el apoyo organizacional son recursos que los servicios de salud laboral y prevención de riesgos deben considerar y fortalecer para ayudar a un retorno exitoso y sostenido al trabajo en supervivientes de cáncer de mama.

Overweight/obesity and physiological variables in workers exposed to rotating shift in a food production factory.

Introduction: Shift work has been hypothesized as a potential risk factor for overweight/obesity or other metabolic changes. We examined the relationship between work shift and body mass index, waist-hip ratio, lipid profile, and glucose concentration in workers from a food manufacturing factory in Colombia. Objectives: To investigate the association between shift work and changes in physiological variables in food manufacturing industry workers in Medellín, Colombia. Methods: This cross-sectional study was conducted with 763 employees from a food manufacturing factory. Information was collected from the medical records from the occupational health provider institution in charge of workers' periodic follow-up. Results: The study sample consisted of 637 (83.5%) men and 126 (16.5%) women. Mean age was 43.35 ± 9.8 years, and mean body mass index was 25.49 ± 3.23 kg/m2. After adjusting for potential confounders, logistic multivariate regression revealed a statistically significant association between shift work and higher body mass index and higher total cholesterol levels compared with dayshift (p < 0.05). Finally, the analysis of waist-hip ratio for each shift scheme and sex showed that this ratio was higher for rotating shift workers, with a significant difference for women. Conclusions: Significant associations were observed between shift work and overweight/obesity and hypercholesterolemia. However, these findings should be confirmed by longitudinal studies.

Introducción: El trabajo por turnos se ha asociado como un potencial factor de riesgo para sobrepeso/obesidad u otras alteraciones metabólicas. Examinamos la relación entre el trabajo por turnos y el índice de masa corporal, índice cintura-cadera, perfil lipídico y glicemia en trabajadores de la industria manufacturera de alimentos en Colombia. Objetivos: Conocer la asociación entre el trabajo por turnos y alteraciones en variables fisiológicos en trabajadores del sector de alimentos en Medellín, Colombia. Métodos: Este estudio transversal fue realizado con 763 trabajadores de una planta del sector de la industria alimentaria. La información fue analizada a partir de registros médicos en la base de datos de una institución prestadora de servicios de salud ocupacional encargada del seguimiento periódico de los trabajadores. Resultados: La muestra del estudio estuvo compuesta por 637 (83,5%) hombres y 126 (16,5%) mujeres. La edad media fue de 43,35 ± 9,8 años y el índice de masa corporal medio de 25,49 ± 3,23 kg/m2. Después de ajustar los posibles factores de confusión, la regresión logística multivariada reveló una asociación estadísticamente significativa entre el trabajo por turno y un mayor índice de masa corporal y nivel de colesterol total, comparado con el turno diurno (p < 0,05). Finalmente, el análisis de la relación cintura-cadera para cada esquema de turno y sexo mostro que esta medida fue mayor para los trabajadores en turno rotativo, siendo significativa la diferencia para las mujeres. Conclusiones: Se observaron asociaciones significativas entre el trabajo por turnos y el sobrepeso/obesidad e hipercolesterolemia; sin embargo, estos hallazgos deben confirmarse mediante estudios longitudinales.

Organizational identification and burnout syndrome in healthcare workers: The mediating effect of organizational justice.

BACKGROUND: Healthcare workers typically perform their work under adverse conditions, increasing their susceptibility to developing burnout syndrome (BO). The paucity of research on the relationship between organizational identification (OI) and perceptions of organizational justice has created the need to address this topic more deeply. OBJECTIVE: This study aimed to assess the relationship between OI and BO, identifying whether perceptions of organizational justice act as mediating variables. METHODS: In total, 402 healthcare workers (physicians, professionals, and nursing assistants) completed Colquitt's (2001) Organizational Justice Scale, Mael and Ashforth's (1992) Organizational Identification Scale, and Maslach's (1986) Burnout Inventory. Two competing structural equation models were evaluated. RESULTS: Our partial mediation model showed that the direct relationship between OI and BO was not significant (ß= -0.16; p = 0.07). Therefore, a total mediation model was selected, showing that the indirect effects of OI on BO through perceptions of distributive justice (ß= -0.16; p = 0.00) and interpersonal justice (ß= -0.11; p = 0.02) were significant. CONCLUSION: Adjusting the processes of health institutions considering a vision of organizational justice and increasing the worker's sense of belonging to his or her organization and his or her work team would, in turn, result in a lower probability of experiencing burnout syndrome.

Altered B cell phenotype and CD27+ memory B cells are associated with clinical features and environmental exposure in Colombian systemic lupus erythematosus patients.

Background: B lymphocytes are dysregulated in Systemic Lupus Erythematosus (SLE) including the expansion of extrafollicular B cells in patients with SLE of African American ancestry, which is associated with disease activity and nephritis. The population of Colombia has a mixture of European, Native American, and African ancestry. It is not known if Colombian patients have the same B cell distributions described previously and if they are associated with disease activity, clinical manifestations, and environmental exposures. Objective: To characterize B cell phenotype in a group of Colombian Systemic Lupus Erythematosus patients with mixed ancestry and determine possible associations with disease activity, clinical manifestations, the DNA methylation status of the IFI44L gene and environmental exposures. Materials and methods: Forty SLE patients and 17 healthy controls were recruited. Cryopreserved peripheral B lymphocytes were analyzed by multiparameter flow cytometry, and the DNA methylation status of the gene IFI44L was evaluated in resting Naive B cells (rNAV). Results: Extrafollicular active Naive (aNAV) and Double Negative type 2, DN2 (CD27- IgD- CD21- CD11c+) B cells were expanded in severe active patients and were associated with nephritis. Patients had hypomethylation of the IFI44L gene in rNAV cells. Regarding environmental exposure, patients occupationally exposed to organic solvents had increased memory CD27+ cells (SWM). Conclusion: aNAV and DN2 extrafollicular cells showed significant clinical associations in Colombian SLE patients, suggesting a relevant role in the disease's pathophysiology. Hypomethylation of the IFI44L gene in resting Naive B cells suggests that epigenetic changes are established at exceedingly early stages of B cell ontogeny. Also, an alteration in SWM memory cells was observed for the first time in patients exposed to organic solvents. This opens different clinical and basic research possibilities to corroborate these findings and deepen the knowledge of the relationship between environmental exposure and SLE.

Efficacy of Transversus Abdominis Plane Block in the Reduction of Pain and Opioid Requirement in Laparoscopic and Robot-assisted Hysterectomy: A Systematic Review and Meta-analysis.

OBJECTIVE: To summarize the available evidence of TAP Block in efficacy in laparoscopic or robotic hysterectomy. DATA SOURCES: We searched databases and gray literature for randomized controlled trials in which transversus abdominis plane (TAP) block was compared with placebo or with no treatment in patients who underwent laparoscopic or robot-assisted hysterectomy. METHOD OF STUDY SELECTION: Two researchers independently evaluated the eligibility of the selected articles. TABULATION, INTEGRATION, AND RESULTS: Seven studies were selected, involving 518 patients. Early postoperative pain showed a difference in the mean mean difference (MD): - 1.17 (95% confidence interval [CI]: - 1.87-0.46) in pain scale scores (I2 = 68%), which was statistically significant in favor of using TAP block, but without clinical relevance; late postoperative pain: DM 0.001 (95%CI: - 0.43-0.44; I2 = 69%); opioid requirement: DM 0.36 (95%CI: - 0.94-1.68; I2 = 80%); and incidence of nausea and vomiting with a difference of 95%CI = - 0.11 (- 0.215-0.006) in favor of TAP. CONCLUSION: With moderate strength of evidence, due to the high heterogeneity and imbalance in baseline characteristics among studies, the results indicate that TAP block should not be considered as a clinically relevant analgesic technique to improve postoperative pain in laparoscopic or robotic hysterectomy, despite statistical significance in early postoperative pain scale scores. CLINICAL TRIAL NUMBER AND REGISTRY: PROSPERO ID - CRD42018103573.

OBJETIVO: Resumir as evidências disponíveis sobre a eficácia do bloqueio TAP em histerectomia laparoscópica ou robótica. FONTES DE DADOS: Pesquisamos bancos de dados e literatura cinza por ensaios clínicos randomizados nos quais o bloqueio do plano transverso do abdome (TAP na sigla em inglês) foi comparado com placebo ou com nenhum tratamento em pacientes que foram submetidos a histerectomia laparoscópica ou assistida por robô. MéTODOS DE SELEçãO DE ESTUDOS: Dois pesquisadores avaliaram independentemente a elegibilidade dos artigos selecionados. TABULAçãO, INTEGRAçãO E RESULTADOS: Sete estudos foram selecionados envolvendo 518 pacientes. A dor pós-operatória precoce apresentou diferença nas médias (DM) de: -1 17 (intervalo de confiança [IC] de 95%: - 1 87­0 46) nos escores da escala de dor (I2 = 68%) o que foi estatisticamente significativo a favor do uso do bloqueio TAP mas sem relevância clínica; dor pós-operatória tardia: DM 0001 (IC95%: - 043­044; I2 = 69%); necessidade de opioides: DM 0 36 (95%CI: - 0 94­168; I2 = 80%); e incidência de náuseas e vômitos com diferença de 95% CI = - 011 (- 0215­0006) a favor do TAP. CONCLUSãO: Com moderada força de evidência devido à alta heterogeneidade e ao desequilíbrio nas características basais entre os estudos os resultados indicam que o bloqueio do TAP não deve ser considerado como uma técnica analgésica clinicamente relevante para melhorar a dor pós-operatória em histerectomia laparoscópica ou robótica apesar da significância estatística nas pontuações da escala de dor pós-operatória inicial.

[Return to work after breast cancer: experience of an oncological referral centre in Medellín, Colombia]. / Reincorporación laboral de mujeres con cáncer de mama: experiencia de un centro oncológico en la ciudad de Medellín.

INTRODUCTION: Advances in the diagnosis and treatment of breast cancer have improved the prognosis for these patients. Consequently, a greater number of survivors are facing the process of returning to work. The objective of the present study was to analyze the frequency, median time and factors related to the return to work of patients with breast cancer, after diagnosis and completion of treatment at a cancer referral center in the city of Medellín, Colombia METHODS: a retrospective cohort study was carried out with registries of patients with breast cancer (n = 141) from a reference cancer center. Sociodemographic, occupational, treatment variables and prevalence of return to work were measured. RESULTS: The average age at diagnosis was 45.8 ± 9 years, Most of the women were premenopausal,and 45% performed manual labour. Advanced disease stage, manual labour, the presence of lymphedema and a greater number of episodes and days of disability werenegatively related to return to work. A total of 93% of patients returned to work. CONCLUSIONS: This study shows that return to work differs according to disease stage, treatment-related factors and type of work.

INTRODUCCIÓN: los avances en el diagnóstico y tratamiento del cáncer de mama han mejorado el pronóstico para estas pacientes, por lo tanto, se espera que un mayor número de supervivientes se enfrenten con el proceso de retornar al trabajo. El objetivo del presente estudio es analizar la frecuencia, la mediana del tiempo, así como los factores relacionados con el retorno al trabajo de pacientes con cáncer de mama, posterior al diagnóstico en un centro de referencia oncológico de la ciudad de Medellín, Colombia. MÉTODOS: estudio de cohorte retrospectiva realizado con los registros de pacientes con cáncer de mama (n=141) atendidas un centro oncológico de referencia. Se midieron variables sociodemográficas, laborales, relacionadas con el tratamiento y de retorno al trabajo. RESULTADOS: la edad promedio al diagnóstico fue de 45.8 ±9 años. La mayoría de las mujeres estaban en la premenopausia, el 45% realizaban trabajo manual. Los indicadores de mayor severidad de la enfermedad, así como el trabajo manual, la presencia de linfedema y un mayor número y días de incapacidad se relacionaron negativamente con el retorno al trabajo de estas pacientes. El 93% de las pacientes retornaron al trabajo. CONCLUSIONES: el retorno al trabajo después de un cáncer de mama difiere según la severidad de la enfermedad, factores relacionados con el tratamiento y tipo de trabajo.

DNA methylation changes on immune cells in Systemic Lupus Erythematosus.

DNA methylation as a process that regulates gene expression is crucial in immune cells biology. Global and gene specific methylation changes have been described in autoimmunity, especially in Systemic Lupus Erythematosus. These changes not only contribute to the understanding of the disease, but also some have been proposed as diagnostic or disease activity biomarkers. The present review compiles the most recent discoveries on this field on each type of immune cells, including specific changes in signalling pathways, genes of interest and its possible applications on diagnosis or treatment.

Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Atypical hepatic haemangiomas.

Hepatic haemangioma is the most common benign liver lesion in the general population. It often exhibits a uniform pattern of characteristics, thus being called "typical." However, a certain number of hepatic haemangiomas have special or uncommon characteristics and are termed "atypical." The majority of patients are asymptomatic. Its differential diagnosis is critical, and its differentiation from other aetiological possibilities can be challenging, especially in cases of atypical haemangiomas, which may lead to confusion or even misleading diagnoses. We report on a 55-year-old patient with atypical multiple hepatic haemangiomas mimicking metastasis or echinococcus infection.

Supervivencia global y libre de enfermedad en mujeres con sobrepeso/obesidad al diagnóstico de cáncer de mama: Un estudio observa-cional de centro único / Overall and disease-free survival in women being over-weight/obesityat the diagnosis of breast cancer. A single-center observationalstudy

Introducción:El objetivo del presente estudio fue evaluar las características clínicas, patológi-cas e histológicas tumorales y su asociación con la recurrencia, metástasis y pronóstico en términos de supervivencia global y libre de enfermedad, de las pacientes que padecen sobre-peso u obesidad al momento del diagnóstico de cáncer de mama.Materiales y métodos:Se condujo un estudio descriptivo,longitudinal,retrospectivo, en un centro oncológico de referencia de Medellín. Se recolectó información de pacientes mayores de 18 años, con cáncer de mama infiltrante temprano y avanzado, entre los años 2012 ­2017, quienes presentaran IMC ≥ 25 kg/m2 al momento del diagnóstico. Las medianas de supervi-vencia se calcularon a través de curvas de Kaplan Meier y las diferencias mediante Log Rank Test.Resultados:Se analizó información de 1.349 pacientes. La mortalidad por todas las causas fue de 13.6% y aumentó proporcionalmente con el IMC (HR = 1.03, IC 1.0-1.05). Se identifica-ron 12.6% de recurrencias y el riesgo con el aumento de IMC no fue estadísticamente signifi-cativo (HR =1.02, IC 0.99 -1.05). Características como mala diferenciación tumoral, invasión linfovascular y estadio tumoral se asociaron de forma univariada con mayor mortalidad.Conclusión:Se demostró una asociación positiva e independiente entre el IMC elevado, la mortalidad y el riesgo de recurrencia en pacientes con cáncer de mama. Así como una aso-ciación con fenotipos tumorales agresivos y características de peor pronóstico. Se sugiere considerar modificaciones en el estilo de vida y un manejo multidisciplinario, como estrate-gias que posiblemente impacten en estos desenlaces

Introduction:The objective of the present study was to evaluate the clinical, pathological, and histological characteristics of tumors and their associations with recurrence, metastasis,and prognosis in terms of overall and disease-free survival inoverweight or obese patients at the time of diagnosis.Materials and methods: A descriptive, longitudinal, retrospective study was conducted at a reference cancer center in Medellin. Information was collected from patients older than 18 years of age with early or advanced infiltrating breast cancer between 2012 and 2017 who had a BMI ≥ 25 kg/m2 at the time of diagnosis. Median survival rates were calculated using Kaplan­Meier curves, and differences were determined using the log-rank test.Results: Information from 1,349 patients was analyzed. All-cause mortality was 13.6% and increased proportionally with BMI (HR = 1.03, CI 1.0-1.05). A total of 12.6% of the recurrences were identified,and the risk with increasing BMI was not significantly different(HR =1.02, CI 0.99 -1.05). Patient characteristicssuch as poor tumor differentiation, lymphovascular inva-sion, and tumor stage were univariately associated with increasedmortality.Conclusion: Positiveand independent associations weredemonstrated between high BMI and mortality and between high BMI and the risk of recurrence in patients with breast cancer. In addition, there wasan association betweenaggressive tumor phenotypes and worse prog-nostic characteristics. Lifestylemodifications and multidisciplinary management should be considered strategies for impactingthese outcomes

Carcinoma con células en anillo de sello primario del cuello uterino: reporte de un caso y revisión de la bibliografía / Primary signet ring cell carcinoma of the cervix: A case report and literature review

Resumen INTRODUCCIÓN: El cáncer de cuello uterino sigue prevaleciendo; sin embargo, el adenocarcinoma cervical primario con células en anillo de sello es raro y está categorizado en los subtipos de adenocarcinomas mucinosos, con menos reportes. Esta neoplasia puede iniciarse con diferentes síntomas ginecológicos y gastrointestinales, que requieren estudios exhaustivos para identificar el foco primario. CASO CLÍNICO: Paciente de 31 años, sin antecedentes patológicos de importancia, con diagnóstico de adenocarcinoma invasor de células en anillo de sello. Inició con sangrado poscoital. En la citología reciente se reportó: lesión intraepitelial de bajo grado, y la colposcopia con inmunohistoquímica positiva para CK7, CK20, CA125, CEA, P16, KI67. En los estudios complementarios se descartaron lesiones metastásicas y se clasificó en estadio IB2. El tratamiento consistió en histerectomía radical, linfadenectomía pélvica, quimioterapia con cisplatino y radioterapia pélvica. A la fecha del último seguimiento la paciente permanecía estable, en controles y libre de la enfermedad. CONCLUSIÓN: El adenocarcinoma con células en anillo de sello primario de cuello uterino es poco frecuente, de diagnóstico complejo en el que debe descartarse la coexistencia de un tumor primario no ginecológico, luego de confirmar el primario en el cuello uterino y ofrecer el tratamiento.

Abstract INTRODUCTION: Cervical cancer remains a prevalent entity, however, primary cervical adenocarcinoma with signet ring cells is a rare condition categorized as one of the subtypes of mucinous adenocarcinomas with fewer scientific reports. This can debut with a wide variety of gynecological and gastrointestinal symptoms that require exhaustive studies to identify the primary focus, therefore this report demonstrates how one of its presentations can be primary of the cervix without presenting gastrointestinal involvement in a patient previously healthy with no risk factors. CLINICAL CASE: A 31-year-old patient with no pathological history diagnosed with an invasive signet ring cell adenocarcinoma who debuted with postcoital bleeding, a cytology that reported a low-grade intraepithelial lesion (LIEB) and colposcopy with positive immunohistochemistry for CK7, CK20, CA125 , CEA, P16, KI67. Complementary studies were performed, metastatic lesions were ruled out, classifying it as stage IB2, a radical hysterectomy, pelvic lymphadenectomy was carried out, after chemotherapy with cisplatin and pelvic radiotherapy. At the date of the last follow-up, the patient is stable, in controls and free of the disease. CONCLUSION: Primary signet ring cell adenocarcinoma of the cervix is a rare entity, with a difficult diagnosis, in which the existence of a non-gynecological primary tumor must be ruled out, and once the primary tumor in the cervix is confirmed, provide the treatment.

Manifestaciones mucocutáneas y su relación con el recuento de linfocitos T CD4 en pacientes infectados con el virus de inmunodeficiencia humana hospitalizados en Medellín, Colombia / Mucocutaneous manifestations and their relationship with CD4 T-lymphocyte count in hospitalized patients infected with the human immunodeficiency virus (HIV) in Medellín, Colombia

Introducción. Entre el 80 y el 95 % de los pacientes infectados por el virus de inmunodeficiencia humana (HIV) desarrollan manifestaciones en la piel que sirven como marcadores de su estado inmunológico. Objetivos. Describir las manifestaciones dermatológicas y los factores clínicos y sociodemográficos de los pacientes hospitalizados con diagnóstico de HIV y su correlación con el recuento de linfocitos T CD4. Materiales y métodos. Se hizo un estudio observacional de corte transversal y retrospectivo a partir del registro de las historias clínicas de 227 pacientes mayores de edad con diagnóstico de HIV, evaluados por dermatología en un hospital de Medellín, Colombia. Resultados. Los 227 registros daban cuenta de 433 manifestaciones dermatológicas, el 64,4 % de ellas infecciosas. Las tres manifestaciones más frecuentes fueron candidiasis oral, condilomas acuminados y reacciones a medicamentos. Se encontró una relación estadísticamente significativa entre el virus del herpes zóster (HZ) diseminado y la sífilis secundaria, con un recuento de CD4 entre 200 y 499 células/mm3 (p=0,04 y 0,028, respectivamente), y entre la candidiasis oral y un recuento de CD4 menor de 100 células/ mm3 (p=0,008). Conclusiones. La relación entre el herpes zóster diseminado y un recuento de CD4 entre 200 y 499 células/mm3 sugiere que, a pesar de los recuentos altos, se pueden presentar formas graves de la enfermedad debido a una posible disfunción de las células T y el agotamiento del sistema inmunológico. La relación entre la candidiasis oral y un recuento de CD4 menor de 100 células/mm3 plantea la posibilidad de considerar esta infección micótica como un marcador importante de debilitamiento inmunológico de los pacientes con HIV.

Introduction. About 80-95% of patients infected with the human immunodeficiency virus (HIV) develop skin manifestations, which are markers of the patients' immune status. Objective. To describe the dermatologic manifestations and the clinical and sociodemographic factors of hospitalized patients diagnosed with HIV and their correlation with CD4 T-lymphocyte count. Materials and methods. We conducted an observational, cross-sectional, and retrospective study of the medical records of 227 adult patients with HIV diagnosis evaluated by dermatology in a hospital in Medellín, Colombia. Results. We included 227 patient records with 433 dermatologic manifestations, 64.4% of them infectious. The most frequent manifestations were oral candidiasis, condylomata acuminata, and drug reactions. Moreover, a statistically significant relationship was found between disseminated herpes zoster virus and secondary syphilis with a CD4 count between 200-499 cells/mm3 (p=0.04 and 0.028, respectively). There was also a statistically significant relationship between oral candidiasis and a CD4 count of less than 100 cells/ mm3 (p=0.008). Conclusions. The relationship between disseminated herpes zoster with CD4 between 200-499 cells/mm3 suggests that, despite having high CD4 counts, severe forms of the disease may occur due to possible T-cell dysfunction and depletion of the immune system. Additionally, the relationship between oral candidiasis and CD4 less than 100 cells/mm3 indicates the potential role of oral candidiasis as an essential marker of weakened immune status in HIV patients.

Efficacy of Transversus Abdominis Plane Block in the Reduction of Pain and Opioid Requirement in Laparoscopic and Robot-assisted Hysterectomy: A Systematic Review and Meta-analysis / Eficácia do bloqueio transverso do plano abdominal na redução da dor e da necessidade de opioides em histerectomia laparoscópica e assistida por robô: Uma revisão sistemática e metanálise

Abstract Objective To summarize the available evidence of TAP Block in efficacy in laparoscopic or robotic hysterectomy. Data Sources We searched databases and gray literature for randomized controlled trials in which transversus abdominis plane (TAP) block was compared with placebo or with no treatment in patients who underwent laparoscopic or robot-assisted hysterectomy. Method of Study Selection Two researchers independently evaluated the eligibility of the selected articles. Tabulation, Integration, and Results Seven studies were selected, involving 518 patients. Early postoperative pain showed a difference in the mean mean difference (MD): - 1.17 (95% confidence interval [CI]: - 1.87-0.46) in pain scale scores (I2=68%), which was statistically significant in favor of using TAP block, but without clinical relevance; late postoperative pain: DM 0.001 (95%CI: - 0.43-0.44; I2=69%); opioid requirement: DM 0.36 (95%CI: - 0.94-1.68; I2=80%); and incidence of nausea and vomiting with a difference of 95%CI=- 0.11 (- 0.215-0.006) in favor of TAP. Conclusion With moderate strength of evidence, due to the high heterogeneity and imbalance in baseline characteristics among studies, the results indicate that TAP block should not be considered as a clinically relevant analgesic technique to improve postoperative pain in laparoscopic or robotic hysterectomy, despite statistical significance in early postoperative pain scale scores.

Resumo Objetivo Resumir as evidências disponíveis sobre a eficácia do bloqueio TAP em histerectomia laparoscópica ou robótica. Fontes de Dados Pesquisamos bancos de dados e literatura cinza por ensaios clínicos randomizados nos quais o bloqueio do plano transverso do abdome (TAP na sigla em inglês) foi comparado com placebo ou com nenhum tratamento em pacientes que foram submetidos a histerectomia laparoscópica ou assistida por robô. Métodos de Seleção de Estudos Dois pesquisadores avaliaram independentemente a elegibilidade dos artigos selecionados. Tabulação, Integração e Resultados Sete estudos foram selecionados envolvendo 518 pacientes. A dor pós-operatória precoce apresentou diferença nasmédias (DM) de: -1 17 (intervalo de confiança [IC] de 95%: - 1 87-0 46) nos escores da escala de dor (I2=68%) o que foi estatisticamente significativo a favor do uso do bloqueio TAP mas sem relevância clínica; dor pós-operatória tardia: DM 0001 (IC95%: - 043-044; I2=69%); necessidade de opioides: DM0 36 (95%CI: - 0 94-168; I2=80%); e incidência de náuseas e vômitos com diferença de 95% CI=- 011 (- 0215-0006) a favor do TAP. Conclusão Com moderada força de evidência devido à alta heterogeneidade e ao desequilíbrio nas características basais entre os estudos os resultados indicam que o bloqueio do TAP não deve ser considerado como uma técnica analgésica clinicamente relevante para melhorar a dor pós-operatória em histerectomia laparoscópica ou robótica apesar da significância estatística nas pontuações da escala de dor pósoperatória inicial.

Clinical, sociodemographic, pharmacological and quality of life characterization of patients with a diagnosis of moderate to severe psoriasis treated in a specialized psoriasis clinic / Caracterización clínica, sociodemográfica, farmacológica y calidad de vida de pacientes con diagnóstico de psoriasis moderada a severa atendidos en una clínica especializada en psoriasis

Abstract Introduction: psoriasis is a systemic, inflammatory, and chronic disease with a global prevalence between 0.6-6.5 %. It is related to multiple comorbidities and generates a significant decrease in quality of life. Objective: to characterize sociodemographic, clinical, pharmacological, and quality of life variables in a population of patients with moderate-severe psoriasis. Methods: descriptive observational study the patients with a diagnosis of severe-moderate psoriasis treated in the Clínica Integral de Psoriasis-CLIPSO between May 2018 - June 2020. A collection format was designed for defined variables and a univariate analysis was performed. Results: 948 patients were identified with a median age of 50 years (IQR: 38-60) of which 51.0 % were women. 23.6 % were incidents with a median treatment time of 114 days (IQR: 98-127) and 73.9 % were prevalent with a median treatment time of 228 days (IQR: 160-371). The type of therapy used was mainly non-biological systemic and 90.9 % of the patients were adherent to the treatment. The clinical variables were similar for both groups and the most common phenotype was psoriasis vulgaris (57.1 %). The health-related quality of life in both groups was greater than 60 points and the affected dimensions were physical and psychological health. 27.3 % of the patients had comorbidities associated with cardiovascular risk and 44.7 % were overweight. Conclusion: knowing the sociodemographic, clinical, pharmacological, and quality of life characteristics of patients with moderate-severe psoriasis allows the identification of risk factors and comprehensive management of the disease.

Association between shift work and being overweight or obese among health care workers in a clinical setting in Medellin, Colombia.

BACKGROUND: Shift work is common in health care settings and has been hypothesized as a risk factor for being overweight or obese. We examined the relation between shift work and being overweight or obese, adjusting for stress and lifestyle habits in Colombian health care workers. OBJECTIVE: The aim of this study was to assess the association between shift work and being overweight/obese in employees of a health care setting in Medellin, Colombia. METHODS: This cross-sectional study was carried out among 200 workers in a health care setting. Participants completed a demographic, occupational, work-related stress and life style questionnaire. Their Body Mass Index (BMI) and waist to hip ratio were also measured. RESULTS: The study sample consisted of 160 (80%) females and 40 (20%) males. Mean age was 35.1±9.1 years and mean BMI was 25±3.9. After adjusting for potential confounders, multivariate logistic regression revealed no statistically significant association between being overweight, being obese or waist to hip ratio and shift work; 95% CI OR: 1.08 (0.62-1.89), 1.33 (0.44-3.99) and 1.2 (0.8-1.9), respectively. Day workers were statistically more likely to smoke, work more hours, and have a higher educational level than shift workers. CONCLUSIONS: No significant associations between shift work and being overweight/obese were observed in health care workers in a Colombian setting. These findings need to be confirmed through longitudinal studies.
