Breast Cancer Tissue Explants: An Approach to Develop Personalized Therapy in Public Health Services.

Breast cancer is one of the main causes of death worldwide. Lately, there is great interest in developing methods that assess individual sensitivity and/or resistance of tumors to antineoplastics to provide personalized therapy for patients. In this study we used organotypic culture of human breast tumor slices to predict the experimental effect of antineoplastics on the viability of tumoral tissue. Samples of breast tumor were taken from 27 patients with clinically advanced breast cancer; slices were obtained and incubated separately for 48 h with paclitaxel, docetaxel, epirubicin, 5-fluorouracil, cyclophosphamide, and cell culture media (control). We determined an experimental tumor sensitivity/resistance (S/R) profile by evaluating tissue viability using the Alamar Blue® metabolic test, and by structural viability (histopathological analyses, necrosis, and inflammation). These parameters were related to immunohistochemical expression of the estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. The predominant histological type found was infiltrating ductal carcinoma (85.2%), followed by lobular carcinoma (7.4%) and mixed carcinoma (7.4%). Experimental drug resistance was related to positive hormone receptor status in 83% of samples treated with cyclophosphamide (p = 0.027). Results suggest that the tumor S/R profile can help to predict personalized therapy or optimize chemotherapeutic treatments in breast cancer.

ctDNA Is Useful to Detect Mutations at Codon 641 of Exon 16 of EZH2, a Biomarker for Relapse in Patients with Diffuse Large B-Cell Lymphoma.

(1) Background: The epigenetic regulator EZH2 is a subunit of the polycomb repressive complex 2 (PRC2), and methylates H3K27, resulting in transcriptional silencing. It has a critical role in lymphocyte differentiation within the lymph node. Therefore, mutations at this level are implicated in lymphomagenesis. In fact, the mutation at the Y641 amino acid in the EZH2 gene is mutated in up to 40% of B-cell lymphomas. (2) Methods: We compared the presence of exon 16 EZH2 mutations in tumor samples and ctDNA in a prospective trial. These mutations were determined by Sanger sequencing and ddPCR. (3) Results: One hundred and thirty-eight cases were included. Ninety-eight were germinal center, and twenty had EZH2 mutations. Mean follow-up (IQR 25-75) was 23 (7-42) months. The tumor samples were considered the standard of reference. Considering the results of the mutation in ctDNA by Sanger sequencing, the sensibility (Se) and specificity (Sp) were 52% and 99%, respectively. After adding the droplet digital PCR (ddPCR) analysis, the Se and Sp increased to 95% and 100%, respectively. After bivariate analysis, only the presence of double-hit lymphoma (p = 0.04) or EZH2 mutations were associated with relapse. The median Progression free survival (PFS) (95% interval confidence) was 27.7 (95% IC: 14-40) vs. 44.1 (95% IC: 40-47.6) months for the mutated vs. wild-type (wt) patients. (4) Conclusions: The ctDNA is useful for analyzing EZH2 mutations, which have an impact on PFS.

Central nervous system international prognostic index impacts overall survival in diffuse large b-cell lymphoma treated with r-chop in a third level cancer center from Mexico: a survey of 642 patients

Background: Central nervous system international prognosis index (CNS-IPI) is validated in European and the USA cancer databases. However, no validation has been done in Mexican population. Objective: The objective of the study was to assess the impact of the CNS-IPI on central nervous system (CNS) relapse and survival in Mexican patients with diffuse large B-cell lymphoma (DLBCL). Methods: In this retrospective analysis, clinical, biochemical, and histological variables and the CNS-IPI were analyzed. Results: Six hundred and forty-two patients with DBLCL were included in the study. The mean ± SD age was 56.8 ± 14.9 years. Most had an ECOG of 0-1: 75% (n = 484) had absence of B-symptoms and advanced disease (clinical stage: III-IV, n = 433, 67.4%). According to the CNS-IPI, almost one-half were in the low-risk category. According to the CNS-IPI, CNS relapse rate was 1.36% (95% CI: 83.2-92.8), 3.1% (95% CI: 132.4-162.8), and 7.4% (95% CI 61-91) for patients in the low-, intermediate-, and high-risk categories, respectively. The median overall survival in the high-risk group (CNS-IPI) was 22 months, and it has not been achieved after 80 months of follow-up for the other groups. Conclusions: CNS-IPI was associated with survival; therefore, we propose its use as a prognostic tool for prospective validation.

A Cohort Study of the Prognostic Impact of Exon-16 EZH2 Mutations in a Mexican-Mestizo Population of Patients with Diffuse Large B-Cell Lymphoma.

BACKGROUND: Novel prognostic factors in patients with diffuse large B-cell lymphoma (DLBCL) are required in the era of Rituximab. OBJECTIVE: The objective of the study was to study the prognostic impact of exon-16 enhancer-of-zeste homolog-2 (EZH2) mutations in patients with DLBCL. METHODS: In a cohort of patients with DLBCL treated between 2015 and 2017, we analyzed the presence of EZH2 mutations and their association with clinical response (CR), relapse, progression-free survival (PFS), and overall survival (OS). RESULTS: A total of 198 patients were included; of them, 30 (15.2%) had mutations at codon 641, in exon 16 of EZH2. Response was achieved in 151 patients (76.3%), and 43 (21.7%) relapsed or progressed during follow-up. EZH2 mutations were associated with relapse/progression (risk ratio [RR] 1.18; 95% confidence interval [CI] 0.98-1.42; p = 0.031), while a trend for not achieving a complete response was observed (RR: 0.876; 95%CI 0.74-1.038; p = 0.071). Of note, Tyr641His and Tyr641Ser EZH2 mutations were associated with shorter PFS (hazard ratio 3.234; 95% CI 1.149-9.1; p = 0.026). CONCLUSION: The presence of EZH2 mutations was negatively associated with relapse/progression and showed a trend for lack of complete response. Further studies are needed to define better the prognostic significance of these mutations in Mexican-Mestizo DLBCL patients.

Late-Onset Hematological Toxicity (LOHT) in Patients with B-Cell Lymphomas: A Survey in 758 Cases

ABSTRACT Background: The increasing survival of patients with non-Hodgkin lymphoma has allowed the diagnosis of long-term complications, including late-onset hematological toxicity (LOHT), transitory cytopenias, or therapy-related myeloid neoplasm (t-MDS/t-AML). Objective: The objective of the study was to determine the frequency and clinical evolution of LOHT in patients with lymphoproliferative malignancies. Materials and Methods: Two cohorts of patients B-cell lymphomas were reviewed. Patients who achieved full hematologic recovery at the end of treatment, and thereafter developed any degree of cytopenia were included in the study. Clinical and biochemical parameters were compared between patients with and without cytopenias with X2 test. Bi- and multivariate analyses were performed to evaluate factors associated with the development of late-onset cytopenias. Results: Of 758 patients enrolled, 19 developed cytopenias (2.5%). Transitory cytopenia was documented in 6 cases, 3 developed ICUS, 8 t-MDS, and 2 t-AML. In patients with FL, only hemoglobin < 12 g/dL (p = 0.032) and >6 nodal areas (p = 0.037) at diagnosis were factors statistically significant for the development of cytopenia. During cytopenias, 55% of patients died. Conclusions: LOHT constitutes a cause of morbidity and mortality in 2.5% of lymphoma patients treated with different therapy regimens.

Validation of the Status epilepticus severity score (STESS) at high-complexity hospitals in Medellín, Colombia.

PURPOSE: The Status Epilepticus Severity Score (STESS) is one of the most well-known clinical scoring systems to predict mortality in status epilepticus (SE). The objective of this study was to validate STESS in a Colombian population. METHOD: We evaluated historical data of adult patients (age ≥16 years) with a clinical or electroencephalographic diagnosis of SE admitted between 2014 and 2017. Prospectively, we included patients admitted from January to June of 2018. The primary outcome was in-hospital mortality. Receiver operating characteristic (ROC)-analysis, determination of best cutoff values, sensitivity, specificity, and positive and negative likelihood ratios were performed. RESULTS: The sample was 395 patients, with in-hospital mortality of 16.8 %. The area under the ROC curve for STESS was 0.84. A cutoff point of ≥3 produced the highest sensitivity of 84.9 % (95 % CI 73.9 %-92.5 %) and a specificity of 65.7 % (95 % CI 60.2 %-70.8 %), with a positive likelihood ratio of 2.5 and a negative likelihood ratio of 0.2. CONCLUSIONS: STESS is a useful tool to predict mortality in patients with SE. In Medellin, Colombia, a STESS < 3 allows the identification of the patients who survive reliably. Those patients with a score <3 may have a better prognosis, and treatment with fewer side effects than anaesthetics could be suggested, always remembering the importance of the treating physician's clinical judgement.

Caracterización clínica epidemiológica de pacientes pediátricos con zika en epidemia / Clinical-epidemiological characterization of pediatric patients with zika in epidemic

Introducción: El zika es considerado una virosis emergente, nunca antes presente en Cuba. Objetivo: Caracterizar desde el punto de vista clínico epidemiológico a pacientes pediátricos con zika confirmado. Métodos: Estudio descriptivo transversal realizado en el Hospital Pediátrico Leonor Pérez entre 2016- 2017, en el transcurso de la epidemia. Se analizaron 140 historias clínicas de pacientes con zika confirmado por reacción en cadena de la polimerasa en suero y orina. Se midieron variables clínicas, de laboratorio y se calculó la tasa asistida. Resultados: La tasa asistida fue 44,35 × 100 casos sospechosos. De las historias clínicas analizadas, 72,1 por ciento correspondió al sexo masculino y el grupo de edad de 10 a 15 años. La reacción en cadena de la polimerasa fue positiva en mayor porcentaje en orina que en suero: 52,1 y 40,7 por ciento respectivamente y en correspondencia con el día de toma de la muestra de orina. El exantema estuvo presente en 84,3 por ciento de pacientes y la fiebre en 70 por ciento. El prurito, ojos rojos, cefalea, malestar general, dolor retroocular, odinofagia, artralgia, anorexia y edemas, se observó en menos de 35 por ciento de los casos. Los promedios de los componentes del hemograma con diferencial y la eritrosedimentación fueron normales. Conclusiones: El exantema y la fiebre son los síntomas de mayor presencia y el estudio en orina por reacción en cadena de la polimerasa informa mayor número de pacientes positivos que en suero, según el momento del ingreso. Los complementarios de rutina son poco sugerentes de zika en los casos sospechosos(AU)

Introduction: Zika virus is considerd as an emergent virus with no previous presence in the Cuban population. Objective: To characterize clinically patients with confirmed Zika virus. Methods: Descriptive cross-sectional study conducted in Leonor Pérez Pediatric Hospital between 2016 and 2017 during the epidemics. There were analyzed 140 clinical records of patients with zika confirmed by chain reaction of polymerase in serum and urine. There were measured clinical and laboratory variables and it was calculated the assisted rate. Results: The assisted rate was 44.35 × 100 suspected cases. From the analyzed clinical records, 72.1 percent corresponded to the male sex and the average age was 10.9 ± 5.5 years. The chain reaction of polimerase was positive in a higher percentage of patients in urine than in serum: 52.1 percent and 40.7 percent, respectively and corresponding with the day when the urine sample was taken. Rash was present in 84.3 percent of the patients and fever in 70.0 percent. Pruritus, red eyes, cephalalgia, general discomfort, pain behind the eyes, odynophagia, arthralgia, anorexia and edemas were observed in less than 35.0 percent of the cases. The averages of the components of blood count with differential and the erythrocyte sedimentation were normal. Conclusions: Rash and fever are the most frequent symptoms and the study of urine by chain reaction of polimerase informs of a higher number of positive patients than in the study of serum, according to the time of admittion. The routine complementary tests are not suggestive of zika in suspected cases(AU)

ABSTRACT Introduction: nocturnal enuresis in children is a frequent reason for attending the doctor's office. Objective: to evaluate the clinical evolution in pediatric patients from 5 to 18 years old with non-organic nocturnal enuresis treated with homeopathic drugs. Methods: a quasi-experimental intervention study was conducted. The sample intentionally comprised 327 patients with nocturnal enuresis from the Homeopathy Clinic at Pepe Portilla Provincial Pediatric Teaching Hospital, from January 2015 to January 2018. Descriptive tools such as frequency tables and percentage calculation were applied to process the data. In addition to the Kolmogorov Smirnov test to compare the trend of the variables between two independent groups. Results: male children between 5 and 11 years old predominated. In both groups, primary enuresis, the characteristic inability to wake up and family history of enuresis prevailed. In the study group, 76.1% had complete response to treatment, only one case had no response, in the control group only 8.3% of patients had complete response. Conclusions: homeopathy is a useful therapeutic modality in the treatment of non-organic nocturnal enuresis in children.

Loneliness, adolescence, and global mental health: Soledad and structural violence in Mexico.

In this article, we call into question recent public health claims that loneliness is a problem of epidemic proportions. Current research on this topic is hindered by an overreliance on limited survey data and by paradigmatic imbalance that delineates the study of loneliness to psychological, cognitive, neuroendocrinological and immunological effects, social functioning, physical health, mortality, and gene effects. The article emphasizes that scientific approaches to the phenomena of loneliness are more appropriately conceived and investigated as inherently matters for social, relational, cultural, and contextual analysis of subjective experience. Studies of loneliness and possible relationships to mental health status require investigations of social, environmental, and institutional structures as well as families, peers, friends, counselors, and health providers. This article takes a step in this direction through examining the lived experience of 35 high school students and their families living under conditions of social adversity in Tijuana, B.C., Mexico, with attention to anxiety and depression. Utilizing ethnographic interviews, observations, and psychological screening tools, we provide an overview for the group and illustrate the interrelations of subjective experience and social environment through a case study. These data reveal the vital role of understandings of loneliness, depression, and anxiety from the perspectives of adolescents themselves. We conclude that future studies of loneliness are best informed by in-depth data on subjective experience in relation to social features to advance understandings within the field of global mental health and allied fields.

CLINICAL CHARACTERISTICS OF PRIMARY EXTRANODAL VERSUS NODAL DIFFUSE LARGE B-CELL LYMPHOMA: A RETROSPECTIVE COHORT STUDY IN A CANCER CENTER.

BACKGROUND: The outcome of patients with primary extranodal diffuse large B-cell lymphoma (PE-DLBCL) varies according to the primary site involved. Primary gastrointestinal, breast, bone, craniofacial, and testicular DLBCL are rare extranodal manifestations of DLBCL. OBJECTIVE: The objective of the study was to describe the clinical course of patients with PE-DLBCL disease in a referral cancer center. RESULTS: From 637 patients, 51 (8.77%) were considered as having PE-DLBCL (25 gastrointestinal, 12 craniofacial, 6 breast, 5 bone, and 3 with primary testicular DLBCL). Complete remission was higher in all PE-DLBCL sites (100% in testicular, 92.6% craniofacial, 83.3% breast, 80% bone, and 80% gastrointestinal) compared with 73.3% in nodal DLBCL. Although 2 cases with breast PE-DLBC relapsed, they achieved a complete response with chemotherapy. The overall survival at 5 years was 100%, 80%, 78%, 58%, 58%, and 62% for patients with primary breast, primary bone, gastrointestinal, primary craniofacial, primary testicular, and nodal DLBCL, respectively. CONCLUSIONS: PE-DLBCLs constitute rare, primary sites of lymphoproliferative disorders in most cases, with localized disease and good prognosis. They require a combined chemoimmunotherapy with radiotherapy in most cases to improve local and systemic disease.

Hemorragia intracerebral como primera manifestación de un coriocarcinoma metastásico: reporte de caso / Intracerebral hemorrhage as the first manifestation of a metastatic choriocarcinoma: case report

RESUMEN El coriocarcinoma es una variante muy vascularizada, invasiva y poco común de la enfermedad trofoblástica gestacional. Es potencialmente fatal sin tratamiento adecuado y se caracteriza por la proliferación maligna de tejido trofoblástico con una alta tasa de metástasis. Se presenta el caso de una paciente joven con hemorragia intracerebral como primera manifestación de un coriocarcinoma metástasico. Se describen las características clínicas e imagenológicas y se hace una revisión de la literatura actual, con énfasis en los detalles más relevantes respecto al diagnóstico diferencial de la hemorragia intracerebral de presentación atípica y el tratamiento más apropiado.

SUMMARY Choriocarcinoma is an invasive, highly vascularized, rare gestational trophoblastic disease. It is potentially fatal without proper treatment and is characterized by malignant proliferation of trophoblastic tissue with a high rate of metastases. We present the case of a young patient with intracerebral hemorrhage as the first manifestation of metasta-tic choriocarcinoma. We describe the clinical and imaging characteristics and review current literature, with emphasis on the most relevant details regarding the differential diagnosis of intracerebral hemorrhage atypical presentation and the most appropriate treatment.

Bisphenol A and adiposity measures in peripubertal boys from the INMA-Granada cohort.

INTRODUCTION: Childhood obesity is one of the most serious public health challenges of our times. Although an important body of experimental evidence highlights the obesogenic potential of endocrine disruptors such as bisphenol A (BPA), the epidemiological evidence remains inconclusive and limited. OBJECTIVE: To assess associations between urinary BPA concentrations and several adiposity measures in peripubertal boys from the Environment and Childhood (INMA) cohort in Granada, Spain. MATERIAL AND METHODS: BPA concentrations were determined in spot urine samples from 298 boys aged 9-11, and their weight, height, waist circumference, and percentage body fat mass were measured. Overweight/obesity was defined as BMI z-score ≥85th percentile and abdominal obesity as waist-to-height ratio (WHtR) ≥0.5. Associations were assessed using multivariable linear and logistic regression models. RESULTS: In adjusted models, each natural log-unit increase in urinary BPA concentrations was associated with higher BMI z-score (ß = 0.22; 95%CI = 0.03, 0.41) and increased odds of overweight/obesity (OR = 1.46; 95%CI = 1.05, 2.05). Children with higher BPA concentrations had higher WHtR values (ß = 0.007; 95%CI = -0.001, 0.015), and BPA was associated with a greater risk of abdominal obesity (OR = 1.45; 95%CI = 1.03, 2.06). No associations were found with % body fat mass. CONCLUSIONS: BPA may exert an obesogenic effect in peripubertal boys, potentially increasing the risk of overweight/obesity, especially abdominal obesity. However, these results should be interpreted with caution given the modest sample size and the possibilities of reverse causality and residual confounding by diet and lifestyle patterns.

Uno de los síntomas más comunes en esta población es la fatiga, reportada entre el 70 y 100% de mujeres sobrevivientes. OBJETIVO: Describir la relación entre tolerancia al ejercicio y la fatiga, en mujeres sobrevivientes de cáncer de mama no metastásico. MATERIALES Y MÉTODOS: Estudio descriptivo transversal en 40 mujeres entre 18 y 65 años, a partir de una base de datos de una institución de alta complejidad en la ciudad de Cali, Colombia. Se identificó la relación entre fatiga y tolerancia al ejercicio con el cuestionario " The Functional Assessment of Cancer Therapy FACT-F" y el test de caminata de los 6 minutos (TC6M). RESULTADOS: El 37,5% de las participantes presentaron fatiga relacionada con cáncer de mama; 33% de las mujeres, disnea al final del TC6M; 37,5%, fatiga en miembros inferiores (Borg modificada), y el 42,5% no alcanzó el 80% de la distancia predicha del TC6M. CONCLUSIÓN: Se encontró una correlación positiva (p 0,000) entre fatiga y tolerancia al ejercicio en mujeres sobrevivientes de cáncer de mama no metastásico.

Transformación leucémica en paciente con linfoma folicular e hiperleucocitosis al diagnóstico / Leukemic transformation in a patient with follicular lymphoma and hyperleukocytosis at diagnosis

La fase leucémica como presentación de un linfoma folicular es rara y debe ser considerada factor de mal pronóstico. Por otra parte, la asociación entre linfoma folicular y síndrome mielodisplásico no se ha descrito. Se presenta el caso de una paciente en la que se detectó marcada leucocitosis y a la que se diagnosticó un linfoma folicular. Recibió quimioterapia con R-CHOP y FCR cuando recayó. Meses después, se realizó un aspirado medular en el cual se observaron cambios compatibles con mielodisplasia, únicamente recibió terapia de soporte y finalmente evolucionó a leucemia mieloide aguda. Aunque se conoce que la mielodisplasia puede ser secundaria al uso de quimioterapia, la paciente presentó además trisomía del cromosoma 11, descrita previamente en mielodisplasia y linfoma tipo Burkitt, la cual pudiera estar en relación con la evolución a leucemia mieloide aguda(AU)

Follicular lymphoma rarely presents with a leukemic phase and this should be considered a negative prognostic factor. Also, follicular lymphoma and myelodysplastic syndrome association has not been previously reported. Herein we present a patient who debuted with marked hyperleukocytosis and was diagnosed with follicular lymphoma, receiving CHOP-R and FCR after she relapsed. Several months later, secondary myelodysplastic changes were observed in her bone marrow. She received supportive therapy and finally progressed into acute myeloid leukemia. Although secondary myelodysplasia is known to be produced by chemotherapy, this patient additionally had trisomy 11, previously described in myelodysplasia and Burkitt's lymphoma, which could be linked to progression to acute myeloid leukemia(AU)

Management of the Heavy Brows: Long-Term Surgical Options.

One of the first signs of aging belongs to the upper third of the face. With the aging process, mestizo facial features become more prominent. The thicker skin-soft tissue envelope (S-STE) has a tendency to sag more, hooding of the eyelids tends to be more pronounced, and there is a tendency for eyebrows to droop, specifically the tail of the brows, because of the loss of support. A "tired" or "sad" look implies that the complex eyebrow-upper eyelid is showing one or more of these signs. Different surgical as well as non-surgical techniques have been described to treat this area, every one of them aiming at making the patient look rested and natural. The objective of this study is to describe a technique for endoscopic brow lifting, consisting on minimal incisions, a biplanar dissection, and a different fixation technique designed for helping reshape the brow. This particular surgical technique has shown the advantage of being minimally invasive and effective. Careful analysis of the patient should be made to decide both the technique and the changes desired by the patient and the surgeon. The authors believe the technique described is another option for approaching and fixating the heavy eyebrows in mestizo patients.
