Are Mycoplasma pneumoniae coinfections frequent in COVID-19 patients? A systematic review.

Understanding the proportion of SARS-CoV-2 patients with Mycoplasmapneumoniae coinfection is crucial for treating patients suffering from coronavirus disease (COVID-19), help to ensure responsible use of antibiotics and minimize the negative consequences of overuse. In addition, this knowledge could have an impact on empirical antibiotic management guidelines for patients with COVID-19. This systematic review aimed to identify the prevalence of M. pneumoniae in patients with coronavirus disease 2019 (COVID-19). A bibliographic search of studies published in Spanish or English was conducted using the PubMed search engine. Fourteen articles from different continents (America, Asia and Europe) were included, involving a total of 5855 patients in these studies. The mean age of COVID-19 patients with M. pneumoniae was 48 years old (range 1-107), most of whom were male. The detection of laboratory-confirmed M. pneumoniae infection varied between 0 and 33.3%. Most of patients referred fever, cough, and dyspnea, and received empirical antibiotic treatment. Bacterial coinfection was not associated with increased ICU admission and mortality. The prevalence of coinfection showed extremely dissimilar figures according to the population studied and diagnostic criteria. However, it is important to develop Latin American studies, given the heterogeneity observed in the studies conducted in different countries. Standardized definitions should be developed in order to be able to assess the impact of coinfections in patients with a diagnosis of COVID-19.

ARTICLESARS-CoV-2 and Chlamydia pneumoniae co-infection:A review of the literature / Coinfección por Chlamydia pneumoniae y SARS-CoV-2: Una revisión de la literatura

Abstract Bacterial co-pathogens are commonly identified in viral respiratory infections and are important causes of morbid-mortality. The prevalence of Chlamydia (C.) pneumoniae infection in patients infected with SARS-CoV-2 has not been sufficiently studied. The objective of the present review was to describe the prevalence of C. pneumoniae in patients with coronavirus disease 2019 (COVID-19). A search in MEDLINE and Google Scholar databases for English language literature published between January 2020 and August 2021 was performed. Studies evaluating patients with confirmed COVID-19 and reporting the simultaneous detection of C. pneumoniae were included. Eleven articles were included in the systematic review (5 case cross-sectional studies and 6 retrospective studies). A total of 18450 patients were included in the eleven studies. The detection of laboratory-confirmed C. pneumoniae infection varied between 1.78 and 71.4% of the total number of co-infections. The median age of patients ranged from 35 to 71 years old and 65% were male. Most of the studies reported one or more pre-existing comorbidities and the majority of the patients presented with fever, cough and dyspnea. Lymphopenia and eosinopenia were described in COVID-19 co-infected patients. The main chest CT scan showed a ground glass density shadow, consolidation and bilateral pneumonia. Most patients received empirical antibiotics. Bacterial co-infection was not associated with increased ICU admission and mortality. Despite frequent prescription of broad-spectrum empirical antimicrobials in patients with coronavirus 2-associated respiratory infections, there is a paucity of data to support the association with respiratory bacterial co-infection. Prospective evidence generation to support the development of an antimicrobial policy and appropriate stewardship interventions specific for the COVID-19 pandemic are urgently required.

Resumen Los patógenos bacterianos pueden detectarse en las infecciones respiratorias virales y son una causa importante de morbimortalidad. La prevalencia de Chlamydia pneumoniae en pacientes infectados con SARS-CoV-2 ha sido poco estudiada. El objetivo de la presente revisión fue describir la prevalencia de C. pneumoniae en pacientes con enfermedad por coronavirus 2019 (COVID-19). Para ello se realizó una búsqueda bibliográfica en Medline y Google Académico, entre enero de 2020 y agosto de 2021. De la revisión surgieron 11 artículos (cinco estudios de casos transversales y seis estudios retrospectivos), que incluyeron un total de 18.450 pacientes. La detección de C. pneumoniae varió entre el 1,78 y 71,4% del total de las coinfecciones. La media de edad de los pacientes osciló entre los 35 y 71 años y el 65% fueron hombres. En la mayoría de los estudios se informaron comorbilidades preexistentes y la mayor parte de los pacientes presentó fiebre, tos y disnea. Además, se describió linfopenia y eosinofilopenia en pacientes con COVID-19 coinfectados. La principal manifestación en la tomografía computarizada fue densidad de vidrio esmerilado, consolidación y neumonía bilateral. La mayoría de los pacientes recibió antibióticos de manera empírica. La coinfección bacteriana no se asoció con un aumento de ingresos en cuidados intensivos ni mortalidad. A pesar de la prescripción de antimicrobianos empíricos en pacientes con infecciones respiratorias asociadas a coronavirus existen pocos reportes de detección de coinfección bacteriana. Es necesario generar evidencia para el desarrollo de políticas antimicrobianas e intervenciones de administración apropiadas y específicas en la pandemia de COVID-19.

Mass Spectrometry Approaches for SARS-CoV-2 Detection: Harnessing for Application in Food and Environmental Samples.

The public health crisis caused by the emergence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in 2019 has drastically changed our lifestyle in virtually all contexts around the world. SARS-CoV-2 is mainly airborne, transmitted by the salivary droplets produced when infected people cough or sneeze. In addition, diarrhea symptoms and the detection of SARS-CoV-2 in feces suggest a fecal-oral route of contagion. Currently, the high demand for SARS-CoV-2 diagnosis has surpassed the availability of PCR and immunodetection probes and has prompted the development of other diagnostic alternatives. In this context, mass spectrometry (MS) represents a mature, robust alternative platform for detection of SARS-CoV-2 and other human viruses. This possibility has raised great interest worldwide. Therefore, it is time for the global application of MS as a feasible option for detecting SARS-CoV-2, not only in human fluids, but also in other matrices such as foods and wastewater. This review covers the most relevant established methods for MS-based SARS-CoV-2 detection and discusses the future application of these tools in different matrices. Significance: The Coronavirus Disease 2019 (COVID-19) pandemic highlighted the pros and cons of currently available PCR and immunodetection tools. The great concern over the infective potential of SARS-CoV-2 viral particles that can persist for several hours on different surfaces under various conditions further evidenced the need for reliable alternatives and high-throughput methods to meet the needs for mass detection of SARS-CoV-2. In this context, MS-based proteomics emerging from fundamental studies in life science can offer a robust option for SARS-CoV-2 detection in human fluids and other matrices. In addition, the substantial efforts towards detecting SARS-CoV-2 in clinal samples, position MS to support the detection of this virus in different matrices such as the surfaces of the packing food process, frozen foods, and wastewaters. Proteomics and mass spectrometry are, therefore, well positioned to play a role in the epidemiological control of COVID-19 and other future diseases. We are currently witnessing the opportunity to generate technologies to overcome prolonged pandemics for the first time in human history.

Magnesium-to-Calcium Ratio and Mortality from COVID-19.

Obesity, type 2 diabetes, arterial hypertension, decrease in immune response, cytokine storm, endothelial dysfunction, and arrhythmias, which are frequent in COVID-19 patients, are associated with hypomagnesemia. Given that cellular influx and efflux of magnesium and calcium involve the same transporters, we aimed to evaluate the association of serum magnesium-to-calcium ratio with mortality from severe COVID-19. The clinical and laboratory data of 1064 patients, aged 60.3 ± 15.7 years, and hospitalized by COVID-19 from March 2020 to July 2021 were analyzed. The data of 554 (52%) patients discharged per death were compared with the data of 510 (48%) patients discharged per recovery. The ROC curve showed that the best cut-off point of the magnesium-to-calcium ratio for identifying individuals at high risk of mortality from COVID-19 was 0.20. The sensitivity and specificity were 83% and 24%. The adjusted multivariate regression model showed that the odds ratio between the magnesium-to-calcium ratio ≤0.20 and discharge per death from COVID-19 was 6.93 (95%CI 1.6-29.1) in the whole population, 4.93 (95%CI 1.4-19.1, p = 0.003) in men, and 3.93 (95%CI 1.6-9.3) in women. In conclusion, our results show that a magnesium-to-calcium ratio ≤0.20 is strongly associated with mortality in patients with severe COVID-19.

Envejecimiento, bases para una titulación / Aging, bases for a degree / Envelhecimiento, bases para um diploma

OPS en su Serie Recursos Humanos para la Salud No 59 informa las dificultades para formar RRHH en Gerontología Geriatría (G-G) dados por aspectos educativos, escasas ofertas laborales y centros asistenciales específicos. El saber en el tema es vasto, no es así el conocimiento que se tiene frente a la problemática en la formación de RRHH identificada en la serie No 59. El objetivo como formadores de enfermeros posgraduados que dejó en "Stand by" una especialidad en G-G, estructurada en la diversidad de la problemática del adulto mayor AM cuyo currículum oculto no colmó las expectativas de la comunidad educativa. La inquietud como profesores, gestores educativos de enfermería, en un departamento que profundiza los saberes sobre le cuidado AM, está en buscar que el programa perfile a un profesional con valores, competencias para el cuidado, contextualizado al Sistema Nacional Integrado Salud (SNIS), lenguaje analítico-crítico y virtual, transdiciplinar entre otras. Que contribuyan a la calidad de vida del AM, la familia, los aspectos sociales, el hábitat. Además de conocer la opinión de los licenciados clínicos. La revisión descriptiva de investigaciones de estudiantes y docentes del departamento en el período 2015-2019 dan cuenta de enunciados textuales y conceptos útiles para este fin, que conjugado a la experiencia docente informa sobre la tendencia buscada. ¿Qué información se ha recogido en las Tesis Finales de Investigación (TFI) que puedan enriquecer una nueva propuesta de formación posbásica en G-G.? La demografía, la experticia de los profesores, la estrategia de posgrados articulados fundamenta la necesidad de un programa posbásico adaptado, que contemple al "life long learning", un aspirante en G-G que aprende métodos para aprender durante toda su vida. La proyección para el 2050 en el Uruguay es de casi 825.000 AM en una población de 3,7 millones, mientras que los menores de 15 serán más de 570.000 la epidemiología misma demandará cuidado enfermero y cambios en la seguridad social.

PAHO in its Human Resources for Health Series No. 59 reports the difficulties to train HR in educational aspects, few job offer and specific care centers in Gerontology Geriatrics (GG) Knowledge on the subject is vast, not so the knowledge that one has in front of the problem in the formation of RR identified in series No 59. The objective as postgraduate nurse educators who left a specialty in G-G in "Stand by", structured in the diversity of the problems of the elderly AM whose hidden curriculum did not exceed the expectations of the educational community. the concern as teachers, nursing educational managers, in a department that deepens knowledge about AM care, is to seek that the program profiles a professional with values, skills for care, contextualized to the SNIS, analytical-critical and virtual language, transdisciplinary among others. That they contribute to the quality of life of the MA, the family, the social aspects, the habit. In addition to knowing the opinion of clinical graduates. the descriptive review of investigations of students and teachers of the department in the period 2015-2019 reveal textual statements and useful concepts for this purpose, which together with the teaching experience reports on the trend sought. What information has been collected in the TFIs that can enrich a new proposal for post-basic training in G-G? The demographics, the expertise of the professors, the articulated postgraduate strategy support the need for an adapted post-basic program, which includes the "lifelong learning", a G-G candidate who learns methods to learn throughout his life. The projection of Uruguay (almost 825,000 AM) in a population of 3.7 million, while those under 15 will be more than 570,000 the epidemiology itself will demand nursing care and changes in social security.

Eficacia de la movilización de células madre en pacientes con Polineuropatía Desmielinizante Inflamatoria Crónica refractaria / Efficacy of mobilization of stem cells in patients with Refractory Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Introducción: La polineuropatía desmielinizante inflamatoria crónica (CIDP) es una enfermedad desmielinizante e inflamatoria de mediación autoinmune. El tratamiento convencional es basado en la inmunomodulación e inmunosupresión. El uso de células madre es una terapia novedosa en los trastornos autoinmune, siendo incluida como terapia. Objetivo: Determinar la eficacia de la movilización de células madre mediante la aplicación del factor estimulador de colonias granulocíticas (F-ECG) en pacientes con CIDP que han recibido otras líneas de tratamiento. Material y Métodos: Se realizó un estudio aleatorizado, doble ciego sobre una cohorte de 45 pacientes con CIDP, donde se administró el (F-ECG) en 25 pacientes y 20 continuaron con el tratamiento habitual, tratados anteriormente con otras variantes terapéuticas por más de tres años, sin respuesta satisfactoria. Resultados: Predominio de los hombres para 64,4 por ciento, la Diabetes Mellitus tuvo mayor asociación y la medicación más usada fueron los esteroides. Los síntomas y signos clínicos mejoraron significativamente tras el tratamiento. Los valores de la puntuación del TCSS al mes y 3 meses después del tratamiento disminuyeron significativamente; pero este decremento no se mantuvo al final del estudio. La velocidad de conducción y el potencial de acción de los nervios sensoriales y motores mejoraron considerablemente después del tratamiento. Conclusiones: La efectividad de la aplicación del (F-ECG) para la mejoría de los síntomas clínicos y resultados de estudios neurofisiológicos evolutivamente son mayores que otras variantes terapéuticas en los primeros meses, con buena seguridad y tolerabilidad, por lo que se puede incluir en la terapéutica convencional para la CIDP(AU)

Introduction: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an autoimmune demyelinating disease. Conventional treatment is based on immunomodulation and immunosuppression. The use of stem cells is a novel therapy in autoimmune disorders, so it is included as therapy. Objective: To determine the efficacy of mobilization of stem cells by applying granulocyte colony-stimulating factor (G-CSF) in patients with CIDP who have followed other lines of treatment. Material and Methods: A randomized, double-blind study was carried out on a cohort of 45 patients with CIDP. G-CSF was administered to 25 patients and 20 of them continued with the usual treatment. These patients were previously treated with other therapeutic variants for more than three years without satisfactory response. Results: There was a prevalence of men (64.4 percent), Diabetes Mellitus had a greater association, and the most used medications were steroids. Clinical symptoms and signs improved significantly after treatment. TCSS scores significantly decreased at one and three months after treatment, but this decrease was not maintained at the end of the study. The conduction velocity and action potential of sensory and motor nerves improved considerably after treatment. Conclusions: The effectiveness of the use of G-CSF shows an improvement of clinical symptoms. The results of neurophysiological studies have a better course than other therapeutic variants during the first months, with good safety and tolerability, so it can be included in the conventional therapy for the CIDP(AU)

Five-Year Outcomes From the Randomized, Phase III Trials CheckMate 017 and 057: Nivolumab Versus Docetaxel in Previously Treated Non-Small-Cell Lung Cancer.

PURPOSE: Immunotherapy has revolutionized the treatment of advanced non-small-cell lung cancer (NSCLC). In two phase III trials (CheckMate 017 and CheckMate 057), nivolumab showed an improvement in overall survival (OS) and favorable safety versus docetaxel in patients with previously treated, advanced squamous and nonsquamous NSCLC, respectively. We report 5-year pooled efficacy and safety from these trials. METHODS: Patients (N = 854; CheckMate 017/057 pooled) with advanced NSCLC, ECOG PS ≤ 1, and progression during or after first-line platinum-based chemotherapy were randomly assigned 1:1 to nivolumab (3 mg/kg once every 2 weeks) or docetaxel (75 mg/m2 once every 3 weeks) until progression or unacceptable toxicity. The primary end point for both trials was OS; secondary end points included progression-free survival (PFS) and safety. Exploratory landmark analyses were investigated. RESULTS: After the minimum follow-up of 64.2 and 64.5 months for CheckMate 017 and 057, respectively, 50 nivolumab-treated patients and nine docetaxel-treated patients were alive. Five-year pooled OS rates were 13.4% versus 2.6%, respectively; 5-year PFS rates were 8.0% versus 0%, respectively. Nivolumab-treated patients without disease progression at 2 and 3 years had an 82.0% and 93.0% chance of survival, respectively, and a 59.6% and 78.3% chance of remaining progression-free at 5 years, respectively. Treatment-related adverse events (TRAEs) were reported in 8 of 31 (25.8%) nivolumab-treated patients between 3-5 years of follow-up, seven of whom experienced new events; one (3.2%) TRAE was grade 3, and there were no grade 4 TRAEs. CONCLUSION: At 5 years, nivolumab continued to demonstrate a survival benefit versus docetaxel, exhibiting a five-fold increase in OS rate, with no new safety signals. These data represent the first report of 5-year outcomes from randomized phase III trials of a programmed death-1 inhibitor in previously treated, advanced NSCLC.

High biochemical recurrence rate after withdrawal of cabergoline in prolactinomas: is it necessary to restart treatment?

PURPOSE: Treatment with dopamine agonists (DA) is highly effective in patients with prolactinomas. In selected patients, discontinuation of DA after several years of successful treatment is possible, however, hyperprolactinemia recurs in 60-80% of them. It is unclear what is the clinical significance of these recurrences and hence, whether or not reinitiation of therapy is necessary. OBJECTIVES: To evaluate the recurrence rate in prolactinoma patients after DA withdrawal and the necessity to restart treatment. METHODS: Patients with >2 years of treatment with cabergoline (CBG) who achieved normoprolactinemia and a > 50% reduction in tumor size were included. DA dose was down titrated until withdrawal. Basal tumor size, as well as PRL and gonadal steroid levels were recorded at diagnosis, at withdrawal of DA and every 3-6 months for 1-3 years. RESULTS: Fifty patients were included (38 women, 34 macroprolactinomas). After withdrawal, 34 (68%) presented recurrence of hyperprolactinemia. PRL levels <5 ng/mL at the time of withdrawal predicted remission (sensitivity 76%, specificity of 63%). CBG was restarted in eight patients (23%) because of the presence of hypogonadism. CBG was withheld in the remaining 26, based on the following arguments: (1) premenopausal women without biochemical hypogonadism, (54%); (2) asymptomatic men under 65 without biochemical hypogonadism (19%); (3) asymptomatic postmenopausal women (19%); (4) asymptomatic men over 65 (8%). After a median follow-up of 30 months, no increase in PRL levels or tumor growth was documented. CONCLUSIONS: Biochemical recurrence in prolactinomas is very frequent, however, in only a few of these patients reinitiation of DA is necessary.

Nutritional support strategies in pediatric cancer patients in Mexico / Estrategias de soporte nutricio en pacientes pediátricos con cáncer en México

Background: Meeting the nutritional needs of pediatric patients on oncology services in low budget public hospitals of Mexico is a continuous challenge, due to its financial resources. Objective: To evaluate the effectiveness of a nutritional strategy for children and adolescents with cancer in a public hospital of Mexico, based on a complacency diet. Methods: Across-sectional study included 58 children and adolescents (1-18 years old). An assessment of nutritional status was applied and a dietary diary was elaborated for 24 hours with the double weight method. Results: 43 patients (74.4%) had an adequate nutritional status. The average energy intake was 72.8% and average protein intake 168.3% of the requirements. The hospital meals accounted for 67.5% of the energy intake, 28.5% resulted from snacks and 3.9% from oral nutritional supplements or polymeric smoothies. Conclusion: The nutritional strategy based on offering a menu at the request supported by smoothies or oral nutritional supplements and the permission to introduce snacks to the hospital offers convenience and flexibility for meal times and favors the energy intake in hospitalized pediatric oncology patients.

Introducción: debido a la escasez de recursos económicos, los hospitales públicos de México tienen un reto continuo para satisfacer las necesidades nutricionales de niños en los servicios de oncología pediátrica. Objetivo: evaluar la eficacia de una estrategia nutricional en niños y adolescentes con cáncer, de un hospital público de México, basada en una dieta a complacencia. Métodos: se llevó a cabo un estudio transversal en el que se incluyeron 58 niños y adolescentes (1-18 años de edad). Se realizó una evaluación antropométrica del estado nutricio y se elaboró un diario dietético durante 24 horas con el método de doble pesada. Resultados: 43 pacientes (74.4%) tenían un estado nutricio adecuado. El consumo promedio de energía fue 72.8% y de proteínas 168.3% del requerimiento. Del total de las calorías consumidas 67.5% provenían del menú hospitalario, 28.5% de refrigerios y 3.9% de suplementos alimenticios o licuados artesanales. Conclusión: la estrategia nutricional basada en una dieta a complacencia apoyada por licuados y suplementos alimenticios más un permiso para la introducción de refrigerios al hospital, favoreció la ingestión calórica, ofreció comodidad y flexibilidad durante las horas de comida a los pacientes oncológicos pediátricos hospitalizados.

Relationship between bone remodeling and metabolism in the elderly / Relación entre la actividad ósea y el metabolismo en el adulto mayor

Background: Recent studies have shown that osteocalcin (OC) is related to not only bone metabolism but also energy metabolism. The aim of the present study was to investigate whether OC was associated with metabolic factors and bone mineral density (BMD) in elderly men. Methods: A cross-sectional study was done including 122 healthy men aged 60 years or older. Serum glucose, lipids, insulin, adiponectin and OC were measured and BMD was estimated using dual energy X-ray absorptiometry. Results: 42.8% of men had metabolic syndrome (MetS). OC levels were not significantly different between men with and without MetS. OC concentrations were inversely associated with body mass index (BMI) (r = −0.226, p = 0.04), waist circumference (r = −0.261, p = 0.02), glucose (r = −0.245, p = 0.03), insulin (r = −0.235, p = 0.03), and HOMA-IR (r = −0.211, p = 0.04). In addition, OC levels were higher in patients with diminished BMD compared with those with normal BMD. Conclusions: OC levels correlate negatively with BMI, waist circumference, glucose, insulin and HOMA-IR in elderly men, which suggests a connection between bone and energy metabolism.

Introducción: diversos estudios sugieren que la osteocalcina (OC) contribuye no solo a la regulación del metabolismo óseo, sino también al metabolismo energético. El objetivo del trabajo fue evaluar la relación entre la concentración sérica de OC y los parámetros metabólicos y la densidad mineral ósea (DMO) en adultos mayores. Métodos: estudio transversal descriptivo en 122 hombres sanos mayores de 60 años. Se les determinó glucosa, lípidos, insulina, adiponectina y OC. La DMO se analizó por absorciometría de doble fotón. Resultados: el 42.8% de la muestra presentó síndrome metabólico (SM). Los niveles de OC no difirieron entre el grupo de pacientes con y sin SM. Se observó una correlación negativa entre la concentración de OC y el índice de masa corporal (IMC) (r = −0.226, p = 0.04), circunferencia de cintura (r = −0.261, p = 0.02), glucosa (r = −0.245, p = 0.03), insulina (r = −0.235, p = 0.03) y HOMA-IR (r = −0.211, p = 0.04). Los pacientes con DMO disminuida mostraron una concentración significativamente mayor de OC en comparación con aquellos con DMO normal. Conclusiones: la OC se asoció inversamente con el IMC, la obesidad abdominal, la glucosa, la insulina y la resistencia a la insulina en hombres mayores de 60 años. Lo anterior confirma la conexión que existe entre el tejido óseo y el metabolismo.

Persistencia de Ac IgM y ADN de M. pneumoniae en pacientes mayores de 18 años con ira / Persistence of Ac IgM and DNA of M. pneumoniae in patients older than 18 years with anger

INTRODUCCIÓN Los métodos moleculares para el diagnóstico de Micoplasma pneumoniae (Mp) son sensibles y más específicos que los serológicos. OBJETIVOS GENERALES Determinar la persistencia de anticuerpos (Ac) IgM y de ADN de Mp en adultos con infección respiratoria aguda (IRA) que requieren internación (casos) y en donantes de sangre.

MÉTODOS Estudio prospectivo, descriptivo y de cohortes que incluyó a >18 años (a) que requerían internación por presentar IRA y donantes de sangre que acudieron entre el 04/16 y 04/17. Los sujetos + por una o dos técnicas se siguieron por un año. Se tomaron muestras respiratorias, sangre y suero. Se utilizaron IF y NPCR. Las diferencias de resultados entre ambos grupos se estimaron mediante la prueba χ². RESULTADOS En 84 casos evaluables se obtuvo 30,9% de IF + y 15,5% de NPCR +. Dos fueron + por ambas pruebas. En 60 donantes se obtuvo 11,6% de IF +, 5% de NPCR +. Uno fue + por ambas pruebas. Las diferencias de resultados + entre casos y donantes fue estadísticamente significativa (p< 0,05). Se siguieron 11 de 37 casos +; 6 tuvieron NPCR + al menos por 2 meses (m) (1 por 10m) y un caso IF + hasta 7m. Se siguieron 6 donantes, 3 fueron IF + por 5m; 2 negativizaron la NPCR a los 2m y uno a los 10m. DISCUSIÓN Se observaron diferencias estadísticamente significativas entre los resultados de casos y donantes. La detección de IgM no permite establecer si la infección es o no reciente (casos + desde 2m a 1 año y hasta 5m en donantes). La NPCR serviría como método confirmatorio de infección reciente, aunque se observó un caso y un donante con persistencia de ADN

Resultados del programa de rehabilitación cardíaca fase II, desarrollado por el Centro Nacional de Rehabilitación, Costa Rica / Results of the phase II cardiac rehabilitation programat the National Center of Rehabilitation, Costa Rica

Objetivo: Debido a la importancia de la enfermedad cardiovascular en Costa Rica y a la escasa información de los programas de rehabilitación cardiaca a nivel nacional, el presente estudio buscó describir los resultados del Programa de Rehabilitación Cardiaca, Fase II, en el Centro Nacional de Rehabilitación. Método: Se trata de un estudio retrospectivo de revisión de expedientes clínicos de pacientes portadores de enfermedades arterial coronaria, remitidos a un programa de rehabilitación cardiaca desde marzo de 2009 a mayo de 2010. De un total de 158 pacientes, 131 finalizaron la fase II. Se comparó la capacidad funcional máxima estimada mediante una prueba de esfuerzos en banda sin fin y el perfil de lípidos. Estas pruebas se realizaron al inicio y al final de esta fase II, la cual consta de 10 a 12 semanas de duración. Resultados: Se obtuvo un aumento significativo de la capacidad funcional estimada en Equivalente Metabólicos (METs), con un promedio equivalente a un 29,7 por ciento al finalizar las 10 a 12 semanas (p< 0,05), valorado mediante una prueba de esfuerzo en banda sin fin; mayor en pacientes de "riesgo alto" con 64,37 por ciento y menor en pacientes de menor edad equivalente a 19,15 por ciento. Se encontró una disminución promedio en el colesterol total de 4.44mg/dl (-2.9por ciento) (p=0.145 por ciento), en las LDL de 0.96mg/dl(-11.2 por ciento) (p 0.016) y un aumento de las HDL en 0.95mg/dl (2.5 por ciento) (p=0.181). Conclusiones: El programa reportó una mejoría de la calidad funcional de los pacientes portadores de enfermedad arterial coronaria en promedio de 28.7 por ciento, con un mayor impacto en pacientes de "alto riesgo" y menor en los pacientes de menor edad. Con respecto al perfil lípido, no se obtuvieron cambios significativos en la medición al cabo de este periodo de entrenamiento.

Asociación de la púrpura trombocitopénica inmunológica y el síndrome de Guillain-Barré: a propósito de un caso / Association of immunologic thrombocytopenia and the Guillain-Barré syndrome: with regard to a case

La púrpura trombocitopénica inmunológica es una enfermedad autoinmune, benigna, de aparición frecuente, caracterizada por la presencia de anticuerpos dirigidos contra las glicoproteínas de la membrana plaquetaria que producen una disminución del recuento plaquetario y manifestaciones hemorrágicas cutáneo-mucosas. El diagnóstico de esta entidad se realiza por exclusión de otras causas de trombocitopenia. El síndrome de Guillain-Barré es también una enfermedad de naturaleza autoinmune donde la pérdida de la tolerancia inmunológica trae como consecuencia la aparición de anticuerpos dirigidos contra los gangliósidos de los nervios periféricos. Se presenta una paciente femenina de 40 años con diagnóstico de una púrpura trombocitopénica inmunológica crónica que comenzó con una parálisis motora ascendente, sin toma respiratoria, parálisis facial y dolor intenso en las regiones dorsal y lumbar. Fue diagnosticada como un síndrome de Guillain-Barré e inmediatamente se comenzó tratamiento con vitaminoterapia y esteroides a altas dosis. Después de varios meses de seguimiento y rehabilitación presentó una evolución satisfactoria con remisión de todos los síntomas neurológicos

The immunologic thrombocytopenic purpura is an autoimmune, benign, of frequent appearance disease characterized by the presence of antibodies directed to glycoproteins of platelet membrane producing a decrease of platelet count and cutaneous-mucosal hemorrhagic manifestations. The Guillain-BarrÚ syndrome is also a disease autoimmune by origin where the loss of immunological tolerance causes the appearance of antibodies directed to gangliosides of peripheral nerves. This is the case of female patient aged 40 diagnosed with a chronic immunologic thrombocytopenic purpura beginning with an ascendant motor paralysis, without respiratory compromise, facial paralysis and intense pain in dorsal and lumbar regions and also a diagnosis of Guillain-BarrÚ syndrome with immediate treatment based on vitamin-therapy and high dose of steroids. After some months of follow-up and rehabilitation there was a satisfactory evolution with remission of all neurological symptoms

Cobertura de tratamiento etiológico para la infección por Trypanosoma cruzi, en niños menores de 15 años, en la república Argentina: período 2003-2006 / Coverage of etiological treatment for infection by Trypanosoma cruzi in children less than 15 years-old in Argentina: period 2003 – 2006

En el marco de las acciones del Programa Nacional de Chagas (PNCh), los criterios de atención del infectado chagásico contemplan la detección precoz de la infección por Trypanosoma cruzi e el tratamiento específico en la población infantil. El presente trabajo busca evaluar la cobertura detratamiento etiológico para Chagas en niños menores de 1 año -Chagas congénito- e entre 1 y 14 añosfase crónica recient durante el período 2003 al 2006. Los datos fueron aportados por los referentes de la Red de Laboratorios de Chagas provinciales e jefes de Programas Provinciales e Jurisdicciones Nacionales de Chagas de la República Argentina, a la Coordinación Nacional de Control de Vectores (CNCV). Se estudiaron 13.866 niños menores de 1 año, con métodos parasitológicos e/o duplasserológicas para la infección por T. cruzi, de los cuales fueron positivos 1.016 niños (7,33por cento) e se trataron 529 (52,07por cento). Por estudios serológicos poblacionales se analizaron 158.640 niños menores de 15 años, de áreas endémicas, se detectaron 4.549 niños positivos (2,87por cento) e se trataron 1.526 (33,55por cento). Del análisis global de los datos (grupos 1 e 2) se observa una heterogeneidad en la cobertura de tratamiento, entre las provincias, siendo en general inadecuada (menor al 50por cento)...
