[Peripartum cardiomyopathy with biventricular failure plus pulmonary thromboembolism and atrial septal defect]. / Miocardiopatía periparto con fallo biventricular más tromboembolismo pulmonar y comunicación interauricular.

This case report examines peripartum cardiomyopathy (PPCM), a rare variant of heart failure with reduced ejection fraction, which manifests at the end of labor or puerperium. The frequency of this pathology varies globally, and its association with risk factors such as genetic disorders, autoimmune diseases, viral infections, suggests a multifactorial etiology. Diagnostic criteria include: Heart failure secondary to left ventricular systolic dysfunction, manifested in the puerperium or at the end of pregnancy and lack of other identifiable causes of heart failure. The case presents a patient with no significant personal pathological history, who, 17 days post cesarean section developed acute symptoms, including abdominal pain, dry cough and dyspnea. Clinical findings revealed hypoxemia, alterations in blood tests and an echocardiogram that confirmed an atrial septal defect. Multidisciplinary management resulted in successful treatment and the patient was discharged without complications. This case highlights the importance of MCPP, a disease with high maternal mortality. The connection between atrial septal defect and PPCM, as well as the involvement of pulmonary thromboembolism.

Peripartum cardiomyopathy: A review.

Peripartum cardiomyopathy is a rare type of heart failure manifesting towards the end of pregnancy or in the months following delivery, in the absence of any other cause of heart failure. There is a wide range of incidence across countries reflecting different population demographics, uncertainty over definitions and under-reporting. Race, ethnicity, multiparity and advanced maternal age are considered important risk factors for the disease. Its etiopathogenesis is incompletely understood and is likely multifactorial, including hemodynamic stresses of pregnancy, vasculo-hormonal factors, inflammation, immunology and genetics. Affected women present with heart failure secondary to reduced left ventricular systolic function (LVEF <45%) and often with associated phenotypes such as LV dilatation, biatrial dilatation, reduced systolic function, impaired diastolic function, and increased pulmonary pressure. Electrocardiography, echocardiography, magnetic resonance imaging, endomyocardial biopsy, and certain blood biomarkers aid in diagnosis and management. Treatment for peripartum cardiomyopathy depends on the stage of pregnancy or postpartum, disease severity and whether the woman is breastfeeding. It includes standard pharmacological therapies for heart failure, within the safety restrictions for pregnancy and lactation. Targeted therapies such as bromocriptine have shown promise in early, small studies, with large definitive trials currently underway. Failure of medical interventions may require mechanical support and transplantation in severe cases. Peripartum cardiomyopathy carries a high mortality rate of up to 10% and a high risk of relapse in subsequent pregnancies, but over half of women present normalization of LV function within a year of diagnosis.

Hematoma hepático subcapsular espontáneo en gestantes / Spontaneous subcapsular hepatic hematoma in pregnant patients

El hematoma hepático subcapsular espontáneo (HHSE) en gestantes, con o sin historia previa de preeclampsia, eclampsia o síndrome HELLP, es una enfermedad poco frecuente durante la gestación y el puerperio (1/45.000-1/225.000 embarazos). Su importancia para el anestesiólogo radica en que asocia una elevada morbimortalidad materna (60-86% y 39%) y neonatal (42%). Tras la sospecha clínica, el diagnóstico de certeza se establece mediante diversas pruebas de imagen; sin embargo, en la mayoría de los casos el diagnóstico del HHSE es un hallazgo casual intraoperatorio asociado a un compromiso materno o fetal. Hoy en día la actuación obstétrica y anestésica ante un HHSE no está estandarizada y depende de su integridad, la estabilidad hemodinámica materna, así como el periodo gestacional en el momento del diagnóstico. La posibilidad de una hemorragia aguda crítica con necesidad de transfusión masiva hace recomendable disponer de protocolos actualizados del tratamiento de la hemorragia obstétrica, adecuándolos a las peculiaridades clínicas de estas pacientes. Tras la fase aguda se debe prestar atención a las complicaciones tromboembólicas.(AU)

Spontaneous subcapsular hepatic hematoma (SSHH) with or without previous history of preeclampsia and/or HELLP syndrome represents a very rare pathological condition in pregnancy and postpartum (1/45,000-1/225,000 pregnancies). Its importance for the anesthesiologist lays in its association with high morbidity and mortality for the mother (60-86%, 39%) and newborn (42%). After a high clinical suspicion, the certainty clinical diagnosis is settled by different imaging techniques. However, in most cases the diagnosis of SSHH is a casual intraoperative finding associated to a maternal or fetal compromise. Nowadays the obstetric and anesthetic management of a SSHH is not standardized and depends on its integrity, hemodynamic stability and the gestational period when diagnosed. The possibility of an acute critic hemorrhage with necessity of massive transfusion, makes advisable to provide updated protocols for the treatment of obstetric hemorrhage, adapting them to the clinical peculiarities of these patients. After the acute phase, close attention should be kept on thromboembolic complications.(AU)

Validation Spanish of the Post-Traumatic Stress Disorder Scale in the Postpartum - City BITS / Validación al castellano de la Escala de Trastorno de Estrés Postraumático en el Postparto - City BITS

Background: Postpartum post-traumatic stress disorder (PTSD) has a prevalence of 3-4% in women, rising to 15-19% in the presence of risks during pregnancy or childbirth, and reaching 39% in the case of neonatal death. Perinatal complications can trigger a real or perceived threat to maternal or neonatal life, which can evoke intense emotional reactions equivalent to a traumatic stressor according to PTSD criteria. Four symptom clusters have been identified: re-experiencing, avoidance, negative cognitions and mood, and hyperarousal symptoms. Despite its high comorbidity with depression and anxiety, postpartum PTSD remains underdiagnosed in maternal settings. The Postpartum Posttraumatic Stress Disorder Scale, originally developed in England, is in the process of translation and global validation. Objective: To validate the Spanish adaptation of the City Birth Trauma Scale. Methods: Quantitative, nonexperimental, cross-sectional, descriptive-correlational study in a sample of 677 Argentine women with children under 12 months of age. Results: Exploratory factor analysis revealed two dimensions that explained 49.56% of the total variance. Confirmatory factor analysis supported the two-factor structure. The scale showed high internal consistency (total α = .903), with α = .872 for 'birth-related symptoms' and α = .886 for 'general symptoms'. Construct validity of the City BiTS was demonstrated by moderate associations with the DASS-21 subscales and a negative correlation with the BIEPS-A. Conclusions: The Spanish adaptation of the City Birth Trauma Scale is confirmed as a reliable and valid instrument, consistent with original research findings and subsequent validations, articulating postpartum PTSD in two symptom categories: birth-related and general.

Introducci�n: El Trastorno de Estr�s Postraum�tico (TEPT) posparto tiene una prevalencia del 3�4% en mujeres, incrementando al 15-19% en presencia de riesgos durante la gestaci�n o parto, y alcanzando un 39% en caso de fallecimiento neonatal. Las complicaciones perinatales pueden desencadenar una amenaza real o interpretada sobre la vida materna o neonatal, lo cual puede suscitar intensas respuestas emocionales equivalentes a un estresor traum�tico seg�n los criterios de TEPT. Se identifican cuatro grupos sintom�ticos: reexperimentaci�n, evitaci�n, cogniciones y estado de �nimo negativos y s�ntomas de hiperactivaci�n. A pesar de su alta comorbilidad con depresi�n y ansiedad, el TEPT posparto permanece subdiagnosticado en contextos maternales. La Escala de Trastorno de Estr�s Postraum�tico en el Postparto, originalmente dise�ada en ingl�s en Inglaterra, est� en proceso de traducci�n y validaci�n global. Objetivo: Validar la adaptaci�n al castellano de The City Birth Trauma Scale. M�todo: Estudio cuantitativo, no experimental, transversal y descriptivo-correlacional en una muestra de 677 mujeres argentinas con hijos menores de 12 meses. Resultados: El an�lisis factorial exploratorio revel� dos dimensiones que explican el 49.56% de la varianza total. El an�lisis factorial confirmatorio respald� esta estructura bifactorial. La escala demostr� una alta consistencia interna (α total = 0.903), siendo α = 0.872 para "S�ntomas relacionados con el parto" y α = 0.886 para "S�ntomas generales". La validez de constructo de City BiTS se evidenci� a trav�s de asociaciones moderadas con las subescalas de DASS-21 y una correlaci�n negativa con BIEPS-A. Conclusi�n: La adaptaci�n al castellano de The City Birth Trauma Scale se confirma como un instrumento confiable y v�lido, alineado con hallazgos de la investigaci�n original y validaciones subsiguientes, articulando el TEPT posparto en dos categor�as sintom�ticas: las relacionadas al parto y las generales.

Trasplante de microbiota fecal por colonoscopía en una mujer embarazada con infección recurrente por Clostridioides difficile

El diagnóstico de la infección por Clostridioides dfficile (ICD) ha aumentado en el embarazo y periparto. Cambios fisiológicos e inmunológicos normales durante el embarazo pueden incrementar el riesgo de ICD. Mujeres embarazadas con ICD tienen una mayor frecuencia de fracaso al tratamiento y una significativa morbilidad y mortalidad. El trasplante de microbiota fecal (TMF) se ha convertido en el tratamiento estándar de la ICD recurrente y refractaria. Sin embargo, existen escasos datos sobre sus resultados en mujeres embarazadas. Presentamos el caso de una mujer embarazada que se sometió con éxito a un TMF para el tratamiento de una ICD recurrente.

The diagnosis of Clostridioides dfficile infection (CDI) in pregnant and peripartum women has increased. In this scenario, there are higher rates of treatment failure and a significant maternal morbidity and mortality. Fecal microbiota transplant (FMT) has become the gold standard for the treatment of recurrent and refractory CDI however, there are few data on its results in pregnant patients. This case showed that FMT could be a therapeutic strategy in pregnant women with recurrent CDI.

Miocardiopatía periparto: revisión de la literatura / Peripartum Cardiomyopathy

Resumen: La Miocardiopatía Periparto es una patología que se presenta como una insuficiencia cardíaca aguda que aparece en el último mes del embarazo o los primeros 5 meses post parto, en ausencia de otra causa identificable. A pesar de ser más frecuente en países Afrodescendientes, el efecto migratorio ha provocado un aumento en su incidencia en los países de América latina, influyendo en la morbimortalidad materna. Si bien su etiología aún no está claramente definida, se han propuesto algunos mecanismos como el aumento del estrés oxidativo, el desequilibrio de la angiogénesis y las reacciones inflamatorias que, en un organismo genéticamente predispuesto, podrían ser los desencadenantes de esta enfermedad. Su manejo aún se considera de soporte, pero se sigue investigando en alternativas terapéuticas que puedan mejorar los resultados a largo plazo. Así, el motivo de esta revisión es evaluar la evidencia disponible hasta el momento, para el enfrentamiento del equipo tratante de estas pacientes.

Abstract: Peripartum Cardiomyopathy is a diseae presenting as acute heart failure that appears in the last month of pregnancy or within 5 months postpartum, in the absence of other identifiable cause. Despite being more frequent in Afro-descendant populations, the migratory effect has caused an increase in its incidence in Latin American countries, influencing maternal morbidity and mortality. Although its etiology is not yet defined, some mechanisms have been proposed such as increased oxidative stress, angiogénesis imbalance and inflammatory reactions that in a genetically predisposed organism, could be the triggers of this disease. Supportive therapy is still the initial management. Therapeutical alternatives that are still being investigated. The main purpose of this review is to evaluate the evidence available to improve the prognosis of the disease.

Peripartum Hysterectomy: Is There Any Difference Between Emergency and Planned Surgeries? / Histerectomia periparto: Existe alguma diferença entre as cirurgias de emergência e planejada?

Abstract Objective To compare the outcomes of emergency and planned peripartum hysterectomies. Methods The present retrospective cross-sectional study was conducted in two hospitals. Maternal and neonatal outcomes were compared according to emergency and planned peripartum hysterectomies. Results A total of 34,020 deliveries were evaluated retrospectively, and 66 cases of peripartum hysterectomy were analyzed. Of these, 31 were cases of planned surgery, and 35 were cases of emergency surgery. The patients who underwent planned peripartum hysterectomy had a lower rate of blood transfusion (83.9% versus 100%; p=0.014), and higher postoperative hemoglobin levels (9.9±1.3 versus 8.3±1.3; p<0.001) compared with the emergency hysterectomy group. The birth weight was lower, although the appearance, pulse, grimace, activity, and respiration (Apgar) scores were higher in the planned surgery group compared with the emergency cases. Conclusion Planned peripartum hysterectomy with an experienced team results in less need for transfusion and improved neonatal outcomes compared with emergency peripartum hysterectomy.

Resumo Objetivo Comparar os resultados das histerectomias periparto de emergência e planejada. Métodos Este estudo transversal retrospectivo foi realizado em dois hospitais. Os resultados maternos e neonatais foram comparados de acordo com as histerectomias periparto de emergência e planejada. Resultados Um total de 34.020 partos foram avaliados retrospectivamente, e 66 casos de histerectomia periparto foram analisados. Destes, 31 eram casos de cirurgias planejadas, e 35, cirurgias de emergência. As pacientes que foram submetidas à histerectomia periparto planejada tiveram uma taxa menor de transfusão de sangue (83,9% versus 100%; p=0,014), e níveis mais elevados de hemoglobina pós-operatória (9,9±1,3 versus 8,3±1,3; p<0,001) em comparação com o grupo de histerectomia de emergência. O peso ao nascer foi menor, embora as pontuações na escala de aparência, frequência cardíaca, irritabilidade reflexa, tônus muscular, e respiração (appearance, pulse, grimace, activity, and respiration, Apgar, em inglês) fossem maiores no grupo da cirurgia planejada em comparação com os casos de emergência. Conclusão A histerectomia periparto planejada com uma equipe experiente resulta em menos necessidade de transfusão e melhora os resultados neonatais em relação à histerectomia periparto de emergência.

Insuficiencia cardiaca congestiva en el embarazo, secundaria a miocardiopatía periparto. Reporte de caso / Congestive heart failure in pregnancy secondary to peripartum cardiomyopathy. Case report

Resumen INTRODUCCIÓN: En Estados Unidos, las cardiopatías periparto se registran en 1 de cada 4000 pacientes. Se consideran idiopáticas y se asocian con enfermedades genéticas, problemas inmunológicos y malformaciones cardiacas, sin que se tenga certeza del origen real de este tipo de enfermedades. La miocardiopatía periparto se asocia con el embarazo y el puerperio; los criterios diagnósticos incluyen: a) insuficiencia cardiaca en las últimas cuatro semanas del embarazo o en los cinco meses siguientes al parto, b) ausencia de causas identificables de insuficiencia cardiaca, c) ausencia de enfermedad cardiaca demostrable antes de las últimas cuatro semanas del embarazo y alteración de la función del ventrículo izquierdo (fracción de eyección del ventrículo izquierdo, menor del 45%). La presentación del caso ayudará a que se tenga conocimiento de este problema. CASO CLINICO: Paciente de 26 años, en curso de las 35.4 semanas de embarazo, con inicio abrupto de signos de cardiopatía congestiva: tos, edema, taquicardia e hipertensión arterial. El embarazo finalizó por cesárea, con traslado inmediato a la unidad de cuidados intensivos. La ecocardiografía reportó una valvulopatía no conocida, insuficiencia ventricular izquierda y disminución de la fracción de eyección del ventrículo izquierdo; con lo anterior se integró el diagnóstico de miocardiopatía periparto. CONCLUSIONES: Las cardiopatías periperiparto son alteraciones excepcionales, con cuadros clínicos debidamente definidos y diagnóstico complejo. Las valvulopatías son el último diagnóstico diferencial de cardiopatía congestiva peripuerperal y se han descrito pocos casos asociados con miocardiopatía periparto.

Abstract BACKGROUND: Peripartum heart disease occurs in 1 out of 4000 cases in the United States; currently, its exact origin is unknown, which is why they are called idiopathic. Genetic diseases, immunological problems and heart malformations have been associated, without being certain about the real origin of these pathologies. Peripartum cardiomyopathy is a rare pathology associated with pregnancy and the puerperium, the diagnosis criteria includes: a) Development of heart failure in the last month of pregnancy or in the 5 months after delivery, b) absence of identifiable causes of heart failure, c) absence of demonstrable heart disease prior to the last month of pregnancy and impaired left ventricular function (FEVI less than 45%). The presentation of the case will help to raise awareness about this problem. CLINICAL CASE: A 26-year-old female patient coursing second gestation in the 35.4 pregnancy week, who debuts abruptly with signs of congestive heart disease such as cough, edema, tachycardia and arterial hypertension. The pregnancy was solved by cesarean section with a subsequent stay in Intensive Care Unit, an unknown valvular disease was identified by echocardiography, as well as left ventricular failure and decreased FEVI. Finally, a definitive diagnosis of peripartum cardiomyopathy was integrated. CONCLUSIONS: Peripartum heart disease is a rare occurrence, with well-defined clinical pictures, but difficult to approach and diagnose. Where valvular heart disease is the last differential diagnosis for peripuerperal congestive heart disease, and few cases associated with peripartum cardiomyopathy have been described.

Miocardiopatía periparto en 2021: ¿con qué contamos para su tratamiento? / Peripartum cardiomyopathy in 2021: what is available for its management?

Resumen Introducción La miocardiopatía periparto (MCPP) es una condición que afecta a mujeres al final del embarazo o durante los primeros meses del periodo puerperal, caracterizada por insuficiencia cardiaca secundaria a disfunción sistólica del ventrículo izquierdo de origen idiopático; por lo tanto, esta se considera un diagnóstico de exclusión. El manejo de la MCPP resulta ser un reto que requiere un abordaje multidisciplinario que debe incluir, como mínimo, al cardiólogo y al obstetra, ya que existen especiales consideraciones debido a las precauciones que deben tomarse en cuenta para conservar la salud fetal y materna. Objetivo Realizar una revisión sobre la evidencia científica disponible hasta la fecha en relación con el tratamiento de la MCPP. Método: Se realizó una revisión sistemática de la literatura en la base de datos PubMed bajo los siguientes términos: peripartum cardiomyopathy, pregnancy and heart failure y pregnancy and cardiomyopathy. Se seleccionaron artículos sin restricción de idioma ni fecha de publicación. Conclusiones Ha habido un incremento en el conocimiento de ciertos aspectos sobre la MCPP en los últimos años; sin embargo, queda mucho por conocer con respecto a sus mecanismos patogénicos. Si bien la bromocriptina parece ofrecer buenos resultados, es necesaria mayor investigación para averiguar su verdadero rol en esta condición. Deben realizarse más estudios para evaluar los posibles beneficios y la seguridad de las nuevas terapias propuestas.

Abstract Introduction Peripartum cardiomyopathy (PPCM) is a condition that affects women towards the end of pregnancy or during the first months after delivery characterized by heart failure secondary to left ventricle systolic dysfunction of idiopathic origin, thus, it is considered as an exclusion diagnosis. PPCM management is a challenge that requires a multidisciplinary approach that must include at least the cardiologist and the obstetrician because of the precautions that must be considered to preserve fetal and maternal health. Objective To perform a review on the evidence available to date regarding the treatment of PPCM. Method A systematic review was performed on the PubMed database using the following terms: peripartum cardiomyopathy, pregnancy and heart failure y pregnancy and cardiomyopathy. Articles were selected with no language or publication date restrictions. Conclusions An increase in awareness of PPCM has occurred during the last few years, however, there is still much to discover about its pathogenic mechanisms. Bromocriptine therapy seems to offer goods results in these patients, further research is needed in order to know its true role in this condition. Other proposed therapies are yet to be studied to know their possible benefits and safety profile.

A propósito de la cardiopatía periparto: una etiología olvidada / Regarding peripartum heart disease: a forgotten etiology

Resumen Objetivo: Identificar la epidemiología clínica y los procesos diagnósticos y terapéuticos de las mujeres con miocardiopatía periparto en un centro de referencia cardiovascular. Método: Se realizó un estudio observacional descriptivo retrospectivo con pacientes de sexo femenino de entre 15 y 50 años con diagnóstico de cardiopatía periparto durante los últimos 10 años en una institución especializada de la ciudad de Medellín. Resultados: Hubo 17 mujeres con diagnóstico de cardiopatía periparto, con una edad media de 31 años (± 6.7). El número promedio de embarazos fue de 1.0, con un 52.9%. Las condiciones más frecuentes durante la gestación fueron obesidad y preeclampsia, con un 23.5% para ambas; se halló diabetes gestacional en una paciente (5.9%) y dos presentaron hemorragia del primer trimestre (11.8%). El 41.2% de las mujeres tuvieron parto vértice espontáneo. Ninguna mujer tuvo antecedentes cardiovasculares. Los síntomas presentados al momento del diagnóstico fueron deterioro de la clase funcional (100%), edema en miembros inferiores (52.9%), ortopnea (76.4%) y disnea paroxística nocturna (88.2%). La terapia farmacológica iniciada incluyó diuréticos (58.8%), inhibidores de la enzima convertidora de angiotensina (IECA) (64.7%), betabloqueadores (82.4%), bromocriptina (5.8%), ivabradina (23.5%) y antagonistas de la aldosterona (64.7%). Conclusiones: Este registro señala la similitud en nuestro medio de esta enfermedad, respecto a la epidemiología, la presentación y el manejo, con el resto del mundo. Muestra que el tratamiento farmacológico para falla cardiaca con la combinación de betabloqueadores, IECA y diuréticos sigue siendo el pilar fundamental en el tratamiento; además, destaca que la miocardiopatía periparto aún es una afección grave, con alta morbilidad y que permanece en insuficiencia cardiaca después del diagnóstico y con un riesgo importante de mortalidad.

Abstract Objective: To identify the epidemiology and the diagnostic and therapeutic processes of women with peripartum cardiomyopathy on a cardiovascular reference center. Method: A retrospective descriptive observational study was conducted with female patients between 15 and 50 years of age with a diagnosis of peripartum cardiomyopathy during the last 10 years. Results: 17 women with a diagnosis of peripartum cardiomyopathy where included, with a mean age of 31 (± 6,7) years at the time of diagnosis. The average number of previous pregnancies was 1.0 in 52.9% of the population. Obesity and preeclampsia were present in 23.5% and 18.8%, respectively. Diabetes was found in one patient (5.9%) and two had hemorrhage of the first trimester (11.8%). 41.2% of the women had a spontaneous vertex delivery. The symptoms presented at the time of diagnosis were deterioration of their functional class in 100.0%, edema in the lower limbs in 52.9%, orthopnea in 76.4% and paroxysmal nocturnal dyspnea in 88.2%. Conclusions: Our data show that peripartum cardiomyopathy occurs with a mode of presentation similar to the rest of the world, pharmacological treatment for heart failure with the combination of beta blockers, ACE inhibitors/ARBs, and diuretics continue to be the fundamental pillar in the treatment of peripartum cardiomyopathy; It is also important to note that peripartum cardiomyopathy remains a serious condition with a high rate of critically ill patients who remain in heart failure after diagnosis with a significant risk of mortality.

The Crying Clinic: Increasing accessibility to Infant Mental Health services for immigrant parents at risk for peripartum depression.

Peripartum depression (PPD) is considered a major public health concern due to its profound impact on families, including infants. In this paper, we report on a pilot initiative designed to reduce barriers and stigma related to the use of traditional infant mental health services for immigrant parents deemed at high risk of PPD. The Crying Clinic (CC) is an innovative walk-in service offered in a culturally diverse Canadian community to support maternal well-being and healthy parent-infant relationships. The CC was designed to be a gateway to existing infant mental health services, through its emphasis on accessibility and cultural sensitivity. Support for concrete concerns, such as anxiety about normative infant behaviors like crying, is underscored in this approach to attract vulnerable families who would otherwise not access mental health support. A review of 44 users, utilization, plans for the use of additional services, and client evaluations suggests that the CC accomplished most of its goals. We conclude that gateway service models such as the CC have the potential to enhance traditional infant mental health programs by creatively addressing the challenge of engaging highly vulnerable parents from culturally diverse backgrounds.

La depresión durante el período inmediatamente antes, durante e inmediatamente después del parto, o peri-parto (PPD) es considerada una preocupación seria de la salud pública debido a su profundo impacto en las familias, incluyendo los infantes (v.g., Howard, Piot y Stein, 2014). En este ensayo, reportamos acerca de una iniciativa experimental diseñada para reducir barreras y el estigma relacionado con el uso de los servicios tradicionales de salud mental infantil por parte de progenitores inmigrantes a quienes se les considera como de alto riesgo con respecto al PPD. La Clínica del Llanto -The Crying Clinic - (CC) en un innovador servicio al que se puede recurrir sin cita previa y que se ofrece en una comunidad canadiense culturalmente diversa con el fin de apoyar el bienestar materno y las saludables relaciones progenitor-infante. La CC fue diseñada para ser una puerta de entrada a los servicios de salud mental infantil existentes, por medio de enfatizar la accesibilidad y la sensibilidad cultural. El apoyo a preocupaciones concretas, tales como la ansiedad acerca de las conductas normativas del infante -el llanto, por ejemplo- es recalcado por medio de este acercamiento para atraer a familias vulnerables que de otra manera no buscarían acceso al apoyo de salud mental. Una revisión de 44 usuarios, la utilización, planes para el uso de servicios adicionales, así como las evaluaciones de los clientes sugieren que la CC alcanzó la mayoría de sus metas. Concluimos con que los modelos de servicios que sirven de puerta de entrada tales como la CC cuentan con el potencial para mejorar los programas tradicionales de salud mental infantil por medio de responder creativamente al reto de atraer a progenitores altamente vulnerables de trasfondos culturales diversos.

La dépression périnatale (PPD) est considérée comme étant un problème de santé publique extrêmement important du fait de son impact profond sur les familles, y compris les nourrissons (par exemple Hoard, Piot, & Stein, 2014). Dans cet article nous faisons part d'une initiative pilote conçue afin de réduire les barrières et le sigma lié à l'utilisation de services de santé mentale traditionnels pour des parents immigrés à risque élevé de PPD. La Clinique Pleurs (en anglais Crying Clinic, soit ici CC) est un service clinique sans rendez-vous innovateur disponible dans une communauté canadienne culturellement diverse pour soutenir le bien-être maternel et des relations parent-nourrisson saines. La CC a été conçue afin d'être une porte d'entrée à des services de santé mentale du nourrisson existants, à travers son accent sur l'accessibilité et la sensibilité culturelle. Le soutien pour des problèmes concrets, comme par exemple l'anxiété à propos de comportements normatifs du nourrisson comme les pleurs, est souligné dans cette approche afin d'attirer des familles vulnérables qui autrement n'accèderaient pas à un soutien de santé mentale. Une étude de 44 utilisateurs, de l'utilisation, des projets pour l'utilisation de services supplémentaires et des évaluations de clients suggère que la CC a rempli la plupart de ses buts. Nous concluons que des modèles de service d'entrée tels que la CC ont le potentiel de mettre en valeur des programmes traditionnels de santé mentale du nourrisson en répondant au défi qu'il y a d'engager des parents extrêmement vulnérables issus de milieux culturellement divers de manière créative.

Congenital cutaneous candidiasis associated with maternal peripartum candidemia.

BACKGROUND: Cutaneous congenital candidiasis (CCC) is a rare condition consisting of invasive fungal infection of the epidermis and dermis that mostly affects preterm infants. Maternal vaginal candidiasis is present in half of the cases, although the occurrence of invasive candidiasis during pregnancy or peripartum period is exceptional. CASE REPORT: We present the case of a full-term infant that was born by vacuum-assisted vaginal delivery to an apparently healthy 33 year-old woman with no history of intravenous drug use or vaginal candidiasis during pregnancy. The newborn showed a diffuse maculopapular rash with respiratory distress and bilateral interstitial lung infiltrates, requiring nasal continuous positive airway pressure support. Blood cultures obtained from the mother due to intrapartum fever yielded Candida albicans. Cultures of vaginal discharge and neonate skin also yielded C. albicans with the same in vitro susceptibly pattern. No alternative source for candidemia was identified. The clinical course after starting a systemic antifungal therapy was favorable in both the mother and the neonate, with clearance of candidemia and resolution of the skin lesions. CONCLUSIONS: CCC must be considered in full-term newborns with maculopapular rash at birth or during the first days of life. The absence of alternative sources for bloodstream infection in the present case suggests a potential etiopathogenic relationship between CCC and maternal candidemia. It is reasonable to rule out postpartum candidemia when CCC is suspected.

Hematological, parasitological and biochemical parameters in sheep during the peripartum period / Parámetros hematológicos, parasitológicos y bioquímicos en ovejas durante el periparto / Parâmetros hematológicos, parasitológicos e bioquímicos de ovelhas durante o periparto

Abstract Background: Pregnancy in all animal species requires special care and attention. During this period there is great variation in hematological and biochemical parameters. Many times these parameters are misinterpreted as being obtained from non-pregnant animals with unknown parasite status. Objective: To characterize the hematological, biochemical, and parasitological values within the peripartum period of Santa Ines sheep naturally infected. Methods: For this purpose, 45 ewes were used, with an average body weight of 50 kg. Data were collected during pregnancy, birth and, lactation. Measurements included body weight, body condition score (BCS), evaluation of conjunctive staining, and collection of blood and feces. Results: All variables changed throughout physiological stages. Weight and BCS were different between periods (p<0.05). Fecal egg counts (FEC) were higher in the peripartum period, with a predominance of Haemonchus ssp, 92.85%. Mean hematological and biochemical values varied throughout the study, (p>0.05). Conclusion: The influence of peripartum on the parameters studied should be considered and its use as a reference value. Regarding the physiological variations observed during peripartum, proper animal management could help minimizing the negative effects of parasitic infections on productivity.

Resumen Antecedentes: La preñez en todas las especies animales requiere atención y cuidados especiales. En ese período existe gran variación en los parámetros hematológicos y bioquímicos. Muchas veces estos parámetros son interpretados erróneamente por ser obtenidos de animales no gestantes y con estatus parasitario desconocido. Objetivo: Caracterizar los valores hematológicos, bioquímicos y parasitológicos durante el periparto en ovejas Santa Inés infectadas naturalmente. Métodos: Se utilizaron 45 ovejas, con un peso corporal promedio de 50 kg. la recolección de muestras se realizó durante la gestación, el parto y la lactancia. Se evaluó el peso, la condición corporal, la tinción conjuntiva, y se recolectaron muestras de sangre y heces. Resultados: Todas las variables mostraron variaciones a lo largo de las etapas fisiológicas. La puntuación de peso y condición corporal (BCS) mostró diferencia entre períodos (p<0,05). Los recuentos de huevos fecales (FEC) tuvieron mayores promedios en el periparto, con predominio de Haemonchus ssp, 92,85%. Los valores medios hematológicos y bioquímicos variaron a lo largo del estudio (p<0,05). Conclusiones: Se recomienda considerar la influencia del periparto en los parámetros estudiados y su uso como valor de referencia. Con respecto a las variaciones fisiológicas observadas durante el periparto, el manejo adecuado de los animales podría ayudar a minimizar los efectos negativos de las infecciones parasitarias sobre la productividad.

Resumo Antecedentes: A prenhez em todas as espécies requer atenção e cuidados especiais. Neste período há grande variação dos parâmetros hematológicos e bioquímicos dos animais. Muitas vezes estes parâmetros são mal interpretados na realização de diagnósticos por serem baseados em parâmetros de animais saudáveis não gestantes, desconsiderando também a infecção parasitária. Objetivo: Caracterizar os valores hematológicos, bioquímicos e parasitológicos durante o periparto de ovelhas da raça Santa Inês naturalmente infectadas. Métodos: Foram utilizadas quarenta e cinco ovelhas, com peso corporal médio de 50 kg, os animais foram acompanhados durante a prenhez, parto e lactação. As análises compreendiam: pesagem, condição corporal, Famacha©, sangue e fezes. Resultados: Todas as variáveis apresentaram variações concomitantemente ao avanço da gestação, parto e lactação. O peso (PS) e o escore da condição corporal (ECC) apresentaram diferença estatística entre os períodos (p>0,05). As contagens de ovos por grama de fezes (FEC) apresentaram médias mais elevadas no periparto. Os valores hematológicos e bioquímicos também variaram (p>0,05). Conclusão: Devido ao resultado, sugere-se considerar a influência de periparto sobre os parâmetros estudados e a sua utilização como um valor de referência. Tendo em vista as variações fisiológicas devido o período do periparto e as infecções parasitárias o manejo dos animais deve ter como objetivo minimizar os impactos negativos na produção animal.

Hematological and biochemical profiles of Mangalarga Marchador mares in the transition period bred on pasture / Perfis hematológico e bioquímico de éguas da raça Mangalarga Marchador no período de transição mantidas a pasto

The present study aimed to evaluate the effects of the transition period on hematological and biochemical constituents in Mangalarga Marchador mares. Forty-eight mares were used to form a maintenance group (MG) and transition group (TG), formed by pregnant mares and, after delivery, infants. Blood samples were collected at the following times: T-60 (60 d pre-delivery), T-30 (30 d pre-delivery), T-15 (15 d pre-delivery), T0 (first 6h post-delivery), T15 (15 d post-delivery), T30 (30 d post-delivery), and T60 (60 d post-delivery). The TG had lower values (P< 0.05) of red blood cells, hematocrit and hemoglobin at T0, T15, T30 and T60 times than MG. The mean corpuscular volume was lower in MG (P< 0.05) than in TG (T0, T15, T30 and T60) and mean corpuscular hemoglobin concentration was higher (P< 0.05) in MG than in TG (T15, T30 and T60). On the other hand, the diameter distribution of red blood cells presented a lower value (P< 0.05) in MG than in TG (T15 and T30). Mares in transition period presented regenerative anemia. The results demonstrate physiological metabolic variations of different intensities during pregnancy, delivery and early lactation.(AU)

O presente estudo teve como objetivo avaliar os efeitos do período de transição em constituintes hematológicos e bioquímicos em éguas Mangalarga Marchador. Foram utilizadas 48 éguas para formar um grupo de manutenção (GM) e um grupo de transição (GT), composto por éguas gestantes e, após o parto, lactentes. Amostras de sangue foram coletadas nos seguintes tempos: T-60 (60 dias pré-parto), T-30 (30 dias pré-parto), T-15 (15 dias pré-parto), T0 (seis primeiras horas pós-parto), T15 (15 dias pós-parto), T30 (30 dias pós-parto) e T60 (60 dias pós-parto). O GT apresentou valores menores (P<0,05) de hemácias, hematócrito e hemoglobina, nos tempos T0, T15, T30 e T60, do que o GM. O volume corpuscular médio foi menor no GM (P<0,05) do que no GT (T0, T15, T30, T60) e a concentração corpórea de hemoglobina corpórea foi maior (P<0,05) no GM do que no GT (T15, T30, T60). Por outro lado, a distribuição do diâmetro dos eritrócitos apresentou um valor menor (P<0,05) no GM do que no GT (T15 e T30). Éguas em período de transição apresentam anemia regenerativa. Os resultados demonstram variações metabólicas de diferentes intensidades durante a gestação, o parto e o início de lactação.(AU)

Miocardiopatía periparto: afección subvalorada / Peripartum cardiomyopathy: An undervalued disease

Resumen: El embarazo es un estado que impone un verdadero reto para el sistema cardiovascular materno. Existe remodelamiento cardiaco, que, junto con el incremento de la masa miocárdica y del tamaño del ventrículo izquierdo y la contractilidad miocárdica disminuida agravada por los cambios del embarazo, pueden condicionar insuficiencia cardiaca aguda durante el periodo periparto. Se considera miocardiopatía periparto cuando la función sistólica del ventrículo izquierdo y los síntomas de insuficiencia cardiaca ocurren en el último mes del embarazo y en los cinco meses posteriores al parto con incidencia de 1 por cada 1300 a 15,000 embarazos. Se comunica el caso de una paciente de 26 años, con antecedente de catarata congénita, que tuvo embarazo normoevolutivo, con parto eutócico, durante el puerperio tuvo disnea y datos de hipoperfusión, mediante evaluación ultrasonográfica pulmonar y cardiaca mostró datos de miocardiopatía dilatada periparto, fue trasladada a un hospital de tercer nivel, donde a pesar del tratamiento intensivo multidisciplinario, falleció. La miocardiopatía periparto es una enfermedad subvalorada con alta mortalidad materna y perinatal; sin embargo, la detección oportuna puede mejorar el tratamiento y el pronóstico. Con la comunicación de este caso, se pretende demostrar la importancia de la detección temprana de una afección poco diagnosticada, como es la miocardiopatía periparto.

Abstract: Pregnancy is a state that imposes a real challenge for the maternal cardiovascular system. There is a cardiac remodeling, which along with an increase in myocardial mass, in left ventricular size and decreased myocardial contractility aggravated by changes in pregnancy, can condition acute heart failure during the peripartum period. Peripartum cardiomyopathy is when the systolic function of the left ventricle and the symptoms of heart failure occur in the last month of pregnancy and in the five months after delivery with an incidence ranging from 1/1300 to 1/15,000 pregnancies. This paper reports the case of a 26-year-old female patient, who had a history of congenital cataract, with normal pregnancy and eutocic delivery; during the puerperium patient showed dyspnea, hypoperfusion data and pulmonary and cardiac ultrasonographic evaluation of peripartum dilated cardiomyopathy, being transferred at a third level, where despite intensive multidisciplinary treatment, the patient died. Peripartum cardiomyopathy is an undervalued disease that has a high maternal and perinatal mortality; however, a timely detection can improve treatment and prognosis. The purpose of this case report is to demonstrate the importance of early detection of a poorly diagnosed entity, such as peripartum cardiomyopathy.

L-carnitine supplementation descreases hepatic triglyceride accumulation in Holstein cows during the transition period / La suplementación con L-carnitina disminuye la acumulación de triglicéridos hepáticos en vacas Holstein durante el periodo de transición / Suplementação com L-carnitina diminui o acúmulo de triglicerídeos hepáticos em vacas Holandesas durante o período de transição

Abstract Background: The increased use of body reserves observed during peripartum leads to higher needs of L-carnitine by cows, which is restrictive under the production conditions of Colombian high tropics. Objective: To evaluate the lipotropic potential of L-carnitine in Holstein dairy cows during the transition period to lactation. Methods: Twenty-one Holstein cows were fed 0, 100, or 200 g/d L-carnitine fumarate from d 260 of gestation to d 20 postpartum. Hepatic triacylglycerides concentration, total carnitine, free carnitine, acylcarnitine, and serum levels of non-esterified fatty acids (NEFA), β-hydroxybutyrate (β-HB) and urea were determined by spectrophotometry. Repeated measures analysis was used to determine the effects of dose, measurement period, and their interactions. Results: Hepatic triglycerides and the different forms of carnitine showed no difference between sampling periods (p>0.05). Hepatic triglycerides concentration was low and decreased in response to 200 g/d L-carnitine fumarate supplementation (p<0.05). This decrease in hepatic triglycerides could be due to increased fatty acid oxidation. L-carnitine supplementation significantly increased (p<0.05) blood urea concentration, possibly through stimulation of the urea cycle, as previously described in other species. Conclusion: Supplementation with L-carnitine decreased the hepatic concentration of triglycerides, possibly due to increased liver oxidation of fatty acids.

Resumen Antecedentes: El incremento en la utilización de reservas corporales durante el periparto en vacas exige una alta disponibilidad de L-carnitina, la cual puede ser limitante bajo las condiciones propias de producción del trópico alto colombiano. Objetivo: Evaluar el potencial lipotrópico de la L-carnitina en vacas lecheras Holstein durante el periodo de transición a la lactancia. Métodos: Se suministraron dosis de 0, 100 y 200 g/d de fumarato de L-carnitina a 21 vacas Holstein a partir del d 260 de gestación y hasta el d 20 postparto. Se determinaron las concentraciones hepáticas de triacilglicéridos, carnitina total, carnitina libre y acil carnitina, y las concentraciones plasmáticas de ácidos grasos no esterificados (NEFA), β-hidroxibutirato (β-HB) y urea. Un análisis de medidas repetidas fue usado para determinar los efectos de la dosis, el periodo de medición, y sus interacciones. Resultados: Las concentraciones hepáticas de triglicéridos y de las diferentes formas de carnitina no difirieron significativamente (p>0,05) entre periodos de muestreo. La concentración hepática de triglicéridos fue baja, y mostró una disminución significativa (p<0,05) en respuesta a la suplementación con 200 g/d de fumarato de L-carnitina. La disminución en los triglicéridos hepáticos podría deberse a un aumento en la oxidación de ácidos grasos. La suplementación con L-carnitina aumentó significativamente (p<0,05) la concentración de urea en sangre, posiblemente a través de un mecanismo de estimulación del ciclo de la urea, descrito previamente en otras especies. Conclusión: La suplementación con L-carnitina disminuyó la concentración hepatica de trigliceridos, debido posiblemente a un aumento en la oxidación de ácidos grasos en hígado.

Resumo Antecedentes: O aumento do uso de reservas corporais durante o periparto requer alta disponibilidade de L-carnitina, que pode ser limitante nas condições de produção no trópico alto colombiano. Objetivo: Avaliar o potencial lipotrópico da L-carnitina em vacas leiteiras Holstein durante o período de transição para a lactação. Métodos: Quantidades de 0, 100 e 200 g/d de fumarato de L-carnitina foram administradas a 21 vacas holandesas durante o d 260 da gestação e até ao d 20 pós-parto. Foram determinadas as concentrações hepáticas de triacilglicerídeos, carnitina total, carnitina livre e acil carnitina e as concentrações plasmáticas de ácidos graxos não esterificados (NEFA), β-hidroxibutirato (β-HB) e ureia. Uma análise das medidas repetidas foi usada para determinar os efeitos da dose, período de medição e suas interações. Resultados: As concentrações hepáticas de triglicerídeos e as diferentes formas de carnitina não diferiram significativamente entre os períodos de amostragem (p>0,05). A concentração hepática de triglicerídeos foi baixa e mostrou diminuição significativa (p<0,05) em resposta à suplementação com 200 g/d de fumarato de L-carnitina. A diminuição dos triglicerídeos hepáticos pode ser devido a um aumento na oxidação de ácidos graxos. A suplementação com L-carnitina aumentou significativamente (p<0,05) a concentração de ureia no sangue, possivelmente através de um mecanismo de estimulação do ciclo da ureia previamente descrito em outras espécies. Conclusão: A suplementação com L-carnitina diminuiu a concentração hepática de triglicerídeos, possivelmente devido ao aumento da oxidação de ácidos graxos no fígado.
