Supportive care needs among older Mexican adults with metastatic cancer.

INTRODUCTION: Supportive care needs may vary according to age. The purpose of this research is to describe and compare supportive care needs between older adults with metastatic cancer (age ≥ 65 years) and their younger counterparts. MATERIALS AND METHODS: We conducted a retrospective secondary analysis of a cohort of patients with newly diagnosed metastatic solid tumors. Supportive care needs were assessed at baseline and at a three-month follow-up. Patients were divided into two groups (aged ≥65/<65 years). Differences in clinical characteristics and supportive care needs were compared utilizing descriptive statistics. Multivariate logistic regression models were employed to identify patient characteristics associated with specific supportive care needs. RESULTS: Between 2018 and 2022, 375 patients were enrolled. Median age was 66 years (interquartile range 19-94). At baseline, older adults had a higher number of supportive care needs (4.8 vs. 4.2, p = 0.01) and were at higher risk of malnutrition (75 vs. 65%, p = 0.05). Increasing age (odds ratio [OR] 1.02 (95% confidence interval [CI] 1.0-1.04, p = 0.03) and an estimated life expectancy <6 months (OR 3.0, 95%CI 1.5-6.1; p < 0.01) were associated with higher odds of malnutrition, while a higher educational level was associated with decreased odds (OR 0.68, 95%CI 0.5-0.8; p < 0.01). At three-month follow-up, older adults still had a higher number of supportive care needs (3.8 vs.2.6, p < 0.01) and were more likely to have fatigue (62 vs. 47%, p = 0.02). An estimated life expectancy of <6 months was associated with increased odds of fatigue (OR 3.0, 95%CI 1.5-6.3; p < 0.01). DISCUSSION: Older adults reported significantly more supportive care needs, particularly risk of malnutrition and fatigue. This information can help in the creation of supportive care services tailored to the needs of older individuals.

Primary Hepatic Neuroendocrine Carcinoma with Metastasis to the Mesentery: A Case Report.

Primary hepatic neuroendocrine carcinomas (PHNECs) are extremely rare, with only about 90 cases having been reported in the English-language literature. Among all neuroendocrine neoplasms, primary hepatic neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) are extremely rare, accounting for 0.3% of NETs and 0.28-0.46% of malignant liver tumors. Additionally, primary hepatic NECs occur infrequently. The clinical diagnosis of primary hepatic NEC remains challenging because of its rarity and the lack of information about its characteristic appearance on images. Consequently, pathological examination through the performance of a preoperative liver tumor biopsy is essential for diagnosis. Due to the lack of availability of substantial high-quality data, there is no standard therapy for primary hepatic NEC. We present the first case of PHNEC metastasized to the mesentery reported in the English-language literature.

Acute lichenoid and varioliform pityriasis in a pediatric patient.

BACKGROUND: Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare dermatosis recognized as a benign condition of unknown etiopathogenesis. It is more common in pediatric patients and young adults and is characterized by multiple small or large erythematous plaques spread over the trunk and extremities. CASE REPORT: We describe the case of a 5-year-old male, previously healthy, with multiple erythematous lesions that disappeared leaving hypopigmented macules. The biopsy reported histological changes suggestive of mycosis fungoides. After a second revision of lamellae in this hospital, lymphocytic vasculitis (LV) with focal epidermal necrosis consistent with acute pityriasis lichenoides (PL) was identified. CONCLUSIONS: The existing knowledge about PLEVA lacks a consensus in specifying its classification, etiopathogenesis, diagnosis, and treatment, so this clinical condition represents a medical challenge. The diagnosis is made by clinical suspicion and confirmed by histology. The objective of this article was to report a case of PLEVA with an atypical presentation due to its histopathological findings, being the first report showing LV in children, as well as a review of the literature.

INTRODUCCIÓN: La pitiriasis liquenoide y varioliforme aguda (PLEVA) es una dermatosis poco frecuente, de etiopatogenia desconocida y evolución autolimitada. Es más común en pacientes pediátricos y adultos jóvenes, y está caracterizada por la presencia de múltiples placas eritematoescamosas pequeñas o grandes, diseminadas en el tronco y las extremidades. CASO CLÍNICO: Se describe el caso de un escolar de 5 años, de sexo masculino, previamente sano, que presentó múltiples cuadros de lesiones eritematosas que desaparecían dejando máculas hipopigmentadas. La biopsia reportó cambios histológicos sugestivos de micosis fungoide. Se realizó una segunda revisión de laminillas, identificando vasculitis linfocítica con necrosis epidérmica focal, consistente con pitiriasis liquenoide aguda. CONCLUSIONES: El conocimiento acerca de la PLEVA carece de un consenso que especifique su clasificación, etiopatogenia, diagnóstico y tratamiento, por lo que esta condición clínica representa un desafío médico. El diagnóstico se realiza por sospecha clínica y se confirma por histología. El objetivo de este artículo fue reportar un caso de PLEVA con presentación atípica por los hallazgos histopatológicos, siendo este el primer reporte de vasculitis linfocítica en niños, y además se realiza una revisión de la literatura.

Evaluación de las características de la prescripción de opioides mayores otorgados por las farmacias de un Hospital General Latinoamericano / Evaluation of the prescription characteristics of major opioids dispensed by the pharmacies of a Latin American General Hospital

Resumen: Introducción: Los opioides se han utilizado para el alivio del dolor en diversos contextos. Su uso puede favorecer efectos indeseables. Actualmente los países industrializados viven una crisis de opioides. Objetivos: Caracterizar los opioides mayores despachados en términos de especialidad médica y de dosis total en miligramos equivalentes a morfina (MME) en un Hospital General Latinoamericano. Material y métodos: Se realizó un estudio retrospectivo y observacional de prescripciones de opioides mayores despachadas en las Farmacias de un Hospital General Latinoamericano entre el año 2017 y 2020. Se tomó información de la base de datos del Ministerio de Salud. Se excluyeron las recetas que contenían estupefacientes no opioides y fentanilo inyectable. Se realizó una estandarización a MME para analizar la distribución de la prescripción según médicos y pacientes. Resultados: La cantidad total de recetas despachadas correspondientes a opioides mayores fue de 5,366 prescripciones. La morfina inyectable fue el medicamento más prescrito (46%) y como principio activo obtuvo 54% de todas las recetas estudiadas (considerando todas las vías de administración). Medicina general prescribió la mayoría de las recetas con un 48%, lo que representó 42% del total de MME. Conclusiones: La morfina es el principio activo preferido por los médicos evaluados en este estudio, la vía de administración parenteral es la más utilizada. Medicina general es el área que más prescribe opioides. Es pertinente crear políticas educativas en materia de opioides; por ello, resulta conveniente caracterizar la prescripción de manera cualitativa considerando información como el diagnóstico y las dosis diarias utilizadas.

Abstract: Introduction: Opioids have been used for pain relief in various settings. Its use can promote undesirable effects. Industrialized countries are currently experiencing an opioid crisis. Objective: To characterize the prescription of major opioids considering the medical area that made the prescription and total dose in milligrams morphine equivalents (MME) at a general hospital in Latin America. Material and methods: A retrospective and observational study was carried out. The number of prescriptions for major opioids dispensed in the pharmacies of a general hospital in Latin America, between 2017 and 2020, were documented. Information was taken from the database of the Ministry of Health. Prescriptions containing non-opioid narcotic drugs and injectable Fentanyl were excluded. A standardization to MME was carried out to analyze the distribution of prescriptions. Results: The total number of prescriptions filled for major opioids was 5,366 prescriptions. Injectable morphine was the most prescribed drug (46%) and as an active principle it obtained 54% of all the prescriptions studied (considering all routes of administration). General medicine prescribed most prescriptions (48%), which represented 42% of the total MME. Conclusions: Morphine is the substance preferred by the doctors evaluated in this study, the parenteral route of administration is the most used. General medicine is the area that prescribes most of the opioids. It is pertinent to create educational policies on opioids; therefore, it is convenient to characterize the prescription qualitatively considering information such as the diagnosis and the daily doses used.

Atypical folliculitis caused by Malassezia spp. in immunosuppressed patients.

BACKGROUND: Folliculitis due to Malassezia spp. (MF), caused mainly by Malassezia furfur, is clinically characterized by an acneiform eruption expressing follicular papules and pustules, predominantly on the trunk. Diagnosis of MF requires confirmation of the presence of yeasts in the hair follicle. The treatment of choice is topical or oral with azoles. We report two cases of folliculitis due to Malassezia spp. of atypical distribution in immunosuppressed patients. CASE REPORTS: Case 1. We describe a 14-year-old male patient diagnosed with chondroid osteosarcoma who required surgical treatment and chemotherapy. He was hospitalized for fever and neutropenia, presenting a rash of papulopustular lesions on the upper and lower extremities and neck. Direct examination and biopsy were performed to conclude the diagnosis of disseminated atypical Malassezia spp. folliculitis. Case 2. We describe a 16-year-old male patient diagnosed with synovial sarcoma, treated with surgical resection and chemotherapy. During hospitalization due to fever and neutropenia, he presented with disseminated dermatosis of the head, trunk, and upper extremities, showing multiple follicular papules and pustules with erythematous base; on the trunk, there were few lesions. In the supraciliary region, he showed erythema and furfuraceous desquamation. Direct examination of a follicle showed thick-walled round yeasts compatible with MF. CONCLUSIONS: MF is a frequent entity but of low diagnostic suspicion. Immunosuppressed patients may manifest atypical clinical characteristics in non-seborrheic areas, implying diagnostic difficulty. Biopsy and direct examination are essential to corroborate the etiology in patients with immunosuppression or with a non-classical presentation.

INTRODUCCIÓN: La foliculitis por Malassezia spp., causada principalmente por Malassezia furfur, se caracteriza clínicamente por una erupción acneiforme, con pápulas y pústulas foliculares de predominio en el tronco. El diagnóstico requiere confirmar la presencia de las levaduras en el folículo piloso. El tratamiento de elección es tópico u oral con azoles. Se reportan dos casos de foliculitis por Malassezia spp. de distribución atípica en pacientes inmunosuprimidos. CASOS CLÍNICOS: Caso 1. Paciente de sexo masculino de 14 años con diagnóstico de osteosarcoma condroide que ameritó tratamiento quirúrgico y quimioterapia. Fue hospitalizado por fiebre y neutropenia, presentando una erupción con lesiones papulopustulosas en las extremidades superiores e inferiores y en el cuello. Se realizaron examen directo y biopsia para concluir el diagnóstico de foliculitis por Malassezia spp. atípica diseminada. Caso 2. Paciente de sexo masculino de 16 años con diagnóstico de sarcoma sinovial, tratado con resección quirúrgica y quimioterapia, hospitalizado por fiebre y neutropenia. Presentó dermatosis diseminada en la cabeza, el tronco y las extremidades superiores, con múltiples pápulas y pústulas foliculares con base eritematosa; en el tronco había escasas lesiones. En la región supraciliar mostró eritema y escama furfurácea. Se realizó examen directo de un folículo, que reportó levaduras redondas de pared gruesa, compatibles con foliculitis por Malassezia spp. CONCLUSIONES: La foliculitis por Malassezia spp. es una afección frecuente, pero de poca sospecha diagnóstica. En pacientes inmunosuprimidos puede manifestarse con una clínica atípica en áreas no seborreicas, lo que implica la dificultad del diagnóstico. La biopsia y el examen directo son fundamentales para corroborar la etiología en pacientes con inmunosupresión o con expresión no clásica.

Cancer pain management in Mexico.

BACKGROUND: Pain control is an essential component of high-quality palliative care. Unfortunately, many low-income and middle-income countries lack an appropriate infrastructure to provide palliative care and suffer from a severe lack of access to opioid analgesics to alleviate pain from various conditions such as cancer. OBJECTIVES: We aimed to review the history and current status of cancer pain management in Mexico, a middle-income Latin American country. Our objective was to identify existing barriers to proper, effective opioid use, as well as provide practical recommendations for improvement. METHODS: Using a search of EBSCOhost database, PubMed and Google, we found official documents and peer-reviewed articles related to health legislation, opioid consumption, palliative care infrastructure and palliative care training in Mexico. RESULTS: Despite advances in palliative care and access to opioids in Mexico, there are still several barriers that undermine effective pain management, showing a major gap between policy and practice. Although Mexican legislation and guidelines include adequate palliative care and pain control as a right for all patients with cancer, the lack of adequate infrastructure and trained personnel severely hampers the implementation of these policies. Additionally, there are important barriers to prescribing opioids, many of which are related to attempts at reducing the consumption of recreational drugs. CONCLUSIONS: Although Mexico has made significant improvements in pain control and palliative care, much needs to be done. Expansion of drug availability, improvement of palliative care training, and constant oversight of regulations and guidelines will help to strengthen Mexico's palliative care services.

Importancia de la adherencia al tratamiento periodontal en pacientes diabéticos y el impacto del desapego / Importance of adherence to periodontal treatment in diabetic patients and the impact of detachment

La diabetes mellitus es una de las enfermedades sistémicas con mayor prevalencia en la población mundial. Este padecimiento representa uno de los factores de riesgo más importantes asociados con la enfermedad periodontal. El paciente con enfermedades crónicas como la diabetes necesita una disciplina convencida diaria y prolongada a través del tiempo (años) como única manera de reducir el impacto sistémico que deteriora la calidad de vida. Cuando se adhiere al tratamiento es posible observarlo en su condición estomatológica; sin embargo, cuando no se logra, se genera un deterioro en las condiciones bucales, principalmente enfermedad periodontal. En este artículo se presentan dos casos clínicos en los cuales se puede observar la mejoría de las condiciones bucales una vez que el paciente decide adherirse a su tratamiento. En el primero se aprecian las manifestaciones de manera notoria de un desapego en años posteriores. Se debe tener en cuenta que la adhesión al tratamiento no sólo depende de factores concernientes al paciente, también intervienen factores asociados al medio ambiente, situación económica, interacción médico-paciente, entre otros, por lo que resulta importante incentivar continuamente y acompañar al paciente en su tratamiento, así como conocer y entender la problemática de una enfermedad sistémica (AU)

Diabetes mellitus is one of the most prevalent systemic diseases in the world population. This condition represents one of the most important risk factors associated with periodontal disease. The patient with chronic diseases such as diabetes needs a daily and prolonged convinced discipline over time (years), as the only way to reduce the systemic impact, which deteriorates the quality of his life: when he has adherence to treatment it is possible to observe it in his stomatological condition, however when it is not achieved, a deterioration in the oral conditions is generated, mainly periodontal disease. This article presents two clinical cases where the improvement of oral conditions can be observed once the patient decides to adhere to their treatment. In the first one, the manifestations of a detachment in later years are noticeable. It should be taken into account that adherence to treatment does not only depend on factors concerning the patient. Also involved are factors associated with the environment, economic situation, doctorpatient interaction, among others, so it is important to continually encourage and accompany the patient in their treatment, as well as to know and understand the problem of a systemic disease (AU)

Impacto de la pandemia en la práctica de los profesionistas de la salud oral en México / Impact of the COVID-19 pandemic in the oral health professionals' practice in Mexico

partir de la pandemia, los odontólogos han presentado una serie de complicaciones en su práctica diaria, la naturaleza misma de la profesión representa un alto riesgo de contagio y la posibilidad de generar una infección cruzada por el virus SARS-CoV-2, por lo que han tenido que limitar su labor a la atención de urgencias, adquiriendo insumos relacionados a incrementar los cuidados de su grupo de trabajo y del paciente. Objetivo: Conocer el impacto de esta plaga en la práctica de los profesionistas de la salud oral en México. Material y métodos: Se realizó un estudio descriptivo y transversal mediante la aplicación de una encuesta a través de redes sociales a odontólogos, los resultados se expresaron con tablas de frecuencias y porcentajes. Resultados: Se recibieron respuestas de 200 cirujanos dentistas con clínica privada, 71% comentó haber cerrado su consultorio al inicio de esta calamidad, en contraste, el 53.5% de profesionales afirmaron tener actualmente una consulta no restringida, refiriendo que se ha visto reducida entre 50 y 75%, la mayoría reconoce que han tenido que reforzar el uso de EPP y algunos protocolos de protección, 16.5% ha padecido COVID-19. Conclusiones: La pandemia ha generado un impacto económico importante en la práctica de los odontólogos, al combinarse la disminución del número de pacientes con el aumento de gastos. Se debe considerar a la odontología como una profesión de alto riesgo, por lo que este gremio debe ser tomado en cuenta para el plan de vacunación como parte importante del sector salud (AU)

Given the nature of their profession, the COVID-19 pandemic has brought complications in their daily practice to odontologists, who are at a high risk of contracting the disease, and the possibility of creating a cross infection by the SARS-CoV-2 virus. That is why odontologists have had to restrain their practice to attend to emergencies only and acquire consumables and equipment related to improve their patients' care and the safety of their work team. Objective: To know the COVID-19 pandemic impact in the oral health professionals' practice in Mexico. Material and methods: A transversal, descriptive study was conducted by using a survey through social networks to gather information from odontologists practicing in Mexico. Results were presented in frequency and percentage tables. Result: Responses of 200 dental surgeons in private practice were received. 71% said that they closed their office at the beginning of the pandemic. On the other hand, 53.5% of them currently have a non-restricted practice but it is reduced between 50 and 75%. Most of them recognized that they had to improve the use of PPE and add some protection protocols, 16.5% have suffered from COVID-19. Conclusions: This pandemic has generated an important economic impact in the odontological practice, combining the decrease in the number of patients with the increase in their office expenses. Odontology must be considered a high-risk profession and an important part of the health sector, consequently, these professionals must be included in the vaccination plan on a priority basis (AU)

Breast Aesthetic Preferences: Analysis of 1294 Surveys.

BACKGROUND: Aesthetic breast perceptions could be variable among cultures. Fullness, superior/inferior pole proportion and orientation and size of the nipple areolar complex are key elements in patient post-operative satisfaction and should be considered when planning breast aesthetic surgery. METHODS: A descriptive study was designed, using an online survey, sent via social media. Standardized software modified images of breasts with different pole proportions, areolar nipple complex orientation and size were used. RESULTS: From 1294 surveys collected, 1291 were analysed (969 women and 322 men). Significant differences in preferences of upper/lower pole breast proportions were found among groups of different age, gender, level of education and previous history of breast surgery. CONCLUSIONS: In the studied population, we found several variations in aesthetic breast preferences related to their demographic characteristics and for this reason we believe that this research may serve as a "macro" guide for both patient and surgeon in primary and secondary breast surgery. To our knowledge, this is the largest survey study concerning breast aesthetic preferences done in Colombia and second largest in the world.

Consideraciones analgésicas sobre el manejo del dolor agudo en el adulto mayor / Considerations for acute pain analgesic management in the elderly

Resumen: En las últimas décadas se ha registrado un aumento dramático en la esperanza de vida. La principal morbilidad de este grupo poblacional son las enfermedades crónico-degenerativas, las cuales frecuentemente se acompañan de dolor. No es de extrañarse que cada vez más pacientes ancianos sean intervenidos quirúrgicamente; hasta 62% de ellos reportan dolor agudo postoperatorio (DAPO) severo. El envejecimiento se asocia a una respuesta reducida al estímulo doloroso, fenómeno conocido como presbialgesia, lo cual se traduce en menores requerimientos analgésicos. Cuando el paciente anciano cuenta con demencia u otras alteraciones de la cognición se deberán utilizar escalas conductuales. Existen diversas condiciones fisiológicas en el anciano que lo hacen propenso a acumulación de fármacos y retraso en su eliminación. Además, existe un riesgo aumentado de interacciones farmacológicas por polifarmacia, hechos que se deberán tener en cuenta al abordar clínicamente el dolor en el paciente geriátrico. Los antiinflamatorios no esteroideos (AINE) son considerados de riesgo en ancianos frágiles por aumentar el riesgo de sangrado, sin mencionar el potencial daño en pacientes nefrópatas o con trastornos de la coagulación. El paracetamol es un analgésico noble a nivel gástrico, renal y cardiovascular. Es considerado primera línea en osteoartrosis degenerativa. Se sugiere no sobrepasar dos gramos al día en ancianos frágiles. Al utilizar analgésicos opioides se sugiere iniciar con la mínima dosis analgésica y escalar lentamente en caso de que el alivio del dolor lo requiera, evitando así efectos adversos.

Abstract: Over the last few decades the elderly population is growing by the second. Most of their illnesses are of the chronic degenerative type, many of which are very painful. Also, more and more elderly patients are requiring surgery for a number of reasons; 62% of these patients will experience severe postoperatory pain. Aging is associated with presbialgesia, which is a reduced response to a noxious stimule. When these patients have dementia or other cognitive impairment conductual scales such must be utilized. There elderly might be more sensitive to analgesic drugs due to various and unique physiological aspects. NSAIDs are considered high risk drugs in fragile elderly patients. Acetaminophen is a safe analgesic drug without many gastrointestinal, renal or cardiovascular secondary effects. Nevertheless, a fragile elderly patient should not receive more than 2 grams daily. When giving opioids, one should start with the minimum dose and titrate slowly when needed in order to avoid adverse effects.

Patient Navigation to Improve Early Access to Supportive Care for Patients with Advanced Cancer in Resource-Limited Settings: A Randomized Controlled Trial.

BACKGROUND: The early integration of supportive care in oncology improves patient-centered outcomes. However, data are lacking regarding how to achieve this in resource-limited settings. We studied whether patient navigation increased access to multidisciplinary supportive care among Mexican patients with advanced cancer. MATERIALS AND METHODS: This randomized controlled trial was conducted between August 2017 and April 2018 at a public hospital in Mexico City. Patients aged ≥18 years with metastatic tumors ≤6 weeks from diagnosis were randomized (1:1) to a patient navigation intervention or usual care. Patients randomized to patient navigation received personalized supportive care from a navigator and a multidisciplinary team. Patients randomized to usual care obtained supportive care referrals from treating oncologists. The primary outcome was the implementation of supportive care interventions at 12 weeks. Secondary outcomes included advance directive completion, supportive care needs, and quality of life. RESULTS: One hundred thirty-four patients were randomized: 67 to patient navigation and 67 to usual care. Supportive care interventions were provided to 74% of patients in the patient navigation arm versus 24% in usual care (difference 0.50, 95% confidence interval [CI] 0.34-0.62; p < .0001). In the patient navigation arm, 48% of eligible patients completed advance directives, compared with 0% in usual care (p < .0001). At 12 weeks, patients randomized to patient navigation had less moderate/severe pain (10% vs. 33%; difference 0.23, 95% CI 0.07-0.38; p = .006), without differences in quality of life between arms. CONCLUSION: Patient navigation improves access to early supportive care, advance care planning, and pain for patients with advanced cancer in resource-limited settings. IMPLICATIONS FOR PRACTICE: The early implementation of supportive care in oncology is recommended by international guidelines, but this might be difficult to achieve in resource-limited settings. This randomized clinical trial including 134 Mexican patients with advanced cancer demonstrates that a multidisciplinary patient navigation intervention can improve the early access to supportive and palliative care interventions, increase advance care planning, and reduce symptoms compared with usual oncologist-guided care alone. These results demonstrate that patient navigation represents a potentially useful solution to achieve the adequate implementation of supportive and palliative care in resource-limited settings globally.

Providing Supportive and Palliative Care Using Telemedicine for Patients with Advanced Cancer During the COVID-19 Pandemic in Mexico.

COVID-19 has overwhelmed the capacity of health care systems, limiting access to supportive and palliative care for patients with advanced cancer. Telemedicine has emerged as a tool to provide care continuity to patients while limiting the risk of contagion. However, implementing telemedicine in resource-limited settings is challenging. We report the results of a multidisciplinary patient-navigator-led telemedicine supportive care program in Mexico City. One-hundred sixty-three telemedicine interventions were provided to 45 patients (median age 68, 57% female). A quarter of the patients had less than or equal to elementary school education, and 15% lived in a rural area. The most common interventions were psychological care (33%), pain and symptom control (25%), and nutritional counseling (13%). Half of the interventions were provided by video conferencing. The most common patient-reported barrier was limited experience using communication technology. Our results demonstrate the feasibility of providing supportive and palliative care interventions using telemedicine in resource-limited settings.

The role of zinc in human health.

El zinc (Zn) es un oligoelemento esencial para muchas funciones biológicas, que incluyen desde la mineralización ósea hasta la transcripción genómica. El déficit en la ingesta de Zn produce alteraciones que en conjunto se han denominado síndrome de deficiencia de Zn. La ingesta diaria recomendada presenta un rango de 7.5 a 15 mg/día para hombres adultos y de 5.5 a 12 mg/día para mujeres adultas. En México, el déficit de Zn es un problema de salud pública, pues afecta a cerca de un cuarto de la población pediátrica nacional. Este documento presenta al lector una mirada global y regional sobre el problema que se aborda, y destaca la necesidad de generar líneas de investigación que aporten mayor información sobre el impacto de este micronutriente en la población mexicana.Zinc (Zn) is an essential trace element for many biological functions including bone mineralization and genomic ­transcription, among others. The set of clinical manifestations deriving from the deficiency of Zn intake are known as Zn deficit syndrome. Zn recommended dietary allowances ranges from 7.5 to 15 mg/day in adult man, and from 5.5 to 12 mg/day in adult females. In Mexico, the deficit of Zn is a public health problem affecting nearly a quarter of pediatric population. This document presents a global and regional overview of this problem, highlighting the need of further research related to the importance of this micronutrient in Mexican population.

Symptom Assessment and Early Access to Supportive and Palliative Care for Patients With Advanced Solid Tumors in Mexico.

BACKGROUND: Early specialized palliative care improves quality of life of patients with advanced cancer, and guidelines encourage its integration into standard oncology care. However, many patients fail to obtain timely palliative/supportive care evaluations, particularly in limited-resource settings. We aimed to determine the proportion of patients with advanced cancer who received an assessment of symptoms and were referred to supportive and palliative care services during the first year after diagnosis in a Mexican hospital. METHODS: Individuals with newly diagnosed advanced solid tumors and 1 year of follow-up at the oncology clinics in the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran in Mexico City from October 2015 to April 2016 were included in this retrospective study. RESULTS: Seventy-seven patients were included. Forty-two (54.5%) were referred to the various supportive care services during the first year after diagnosis, and 23 (29.8%) were referred to the palliative care clinic. The most commonly assessed symptoms by oncologists were pain (77.9%), anorexia (74.0%), fatigue (68.8%), and nausea (55.8%), while depression/anxiety were evaluated in 10 (12.9%) patients. The oncologist offered to clarify treatment goals in 39 (50.6%) cases and evaluated the understanding of diagnosis/illness and prognosis in 22 (28.5%). CONCLUSION: Palliative and supportive care services were widely underutilized, which may be related to a lack of standardized symptom assessments and poor end-of-life communication. Novel strategies are needed to improve the implementation of tools for systematic symptom assessment and to optimize the integration of supportive care interventions into oncology care in developing countries.

Cross-Reaction, Enhancement, and Neutralization Activity of Dengue Virus Antibodies against Zika Virus: A Study in the Mexican Population.

Zika virus (ZIKV), an emerging mosquito-borne flavivirus, has quickly spread in many regions around the world where dengue virus (DENV) is endemic. This represents a major health concern, given the high homology between these two viruses, which can result in cross-reactivity. The aim of this study was to determine the cross-reacting antibody response of the IgM and IgG classes against the recombinant envelope protein of ZIKV (rE-ZIKV) in sera from patients with acute-phase infection of different clinical forms of dengue, i.e., dengue fever (DF) and dengue hemorrhagic fever (DHF) (before the arrival of ZIKV in Mexico 2010), as well as acute-phase sera of ZIKV patients, together with the implications in neutralization and antibody-dependent enhancement. Differences in IgM responses were observed in a number of DF and DHF patients whose sera cross-reacted with the rE-ZIK antigen, with 42% recognition between acute-phase DHF and ZIKV but 27% recognition between DF and ZIKV. Regarding IgG antibodies, 71.5% from the DF group showed cross-reactivity to rE-ZIKV in contrast with 50% and only 25% of DHF and ZIKV serum samples, respectively, which specifically recognized the homologous antigen. The DHF group showed more enhancement of ZIKV infection of FCRγ-expressing cells compared to the DF group. Furthermore, the DHF group also showed a higher cross-neutralizing ability than that of DF. This is the first report where DF and DHF serum samples were evaluated for cross-reactivity against Zika protein and ZIKV. Furthermore, DENV serum samples cross-protect against ZIKV through neutralizing antibodies but at the same time mediate antibody-dependent enhancement in the sequential ZIKV infection.
