Mexican patient with Ellis-van Creveld syndrome and cleft palate: Importance of functional hemizygosity and phenotype expansion.

BACKGROUND: Ellis-van Creveld syndrome (EvCS) is a chondroectodermal dysplasia caused by germline pathogenic variants in ciliary complex subunit 1 and 2 genes (EVC, EVC2) on chromosome 4p16.2. This disease has a broad phenotype, and there are few described phenotype-genotype correlations. METHODS: Ethical Compliance: Written informed consent was obtained from the parents. Here, we report a genetically confirmed Mexican patient with EvCS having two inherited pathogenic variants in trans in EVC2: c.[1195C>T];[2161delC]. RESULTS: This patient allowed a genotypic-phenotypic comparison with another Mexican subject who presented a more attenuated phenotype; furthermore, our patient also presented cleft palate, a rarely reported feature. CONCLUSION: Our case shows the importance of comparing functional hemizygosity between patient's phenotypes when they share a variant, and our case also supports the association of alterations in the palate as part of the EvCS phenotype.

Interrupción del embarazo en nefritis lúpica: un análisis bioético desde el método integral / Termination of pregnancy in lupus nephritis: A bioethical analysis with the integrative method

Antecedentes y objetivo: La interrupción del embarazo en pacientes con enfermedades reumatológicas es controvertida y pocas veces se realiza un análisis bioético. En este estudio analizamos el caso de una paciente embarazada con nefritis lúpica sin respuesta a tratamiento a quien se le planteó la interrupción del embarazo. Métodos: Se aplicó el modelo integral, incluyendo distintos sistemas normativos para el análisis del dilema. Resultados: Desde el utilitarismo es justificable la interrupción del embarazo, buscando el mayor beneficio para la mayoría de las partes. La deontología justifica tanto continuar como interrumpir el embarazo, centrando la importancia en la acción misma y en la autonomía. Para la ética de la virtud, la importancia de las decisiones recae en la persona que realiza la acción buscando el florecimiento: la interrupción del embarazo sería justificable. Discusión y conclusiones: La interrupción del embarazo sería una solución adecuada según el modelo integral. El análisis bioético de casos paradigmáticos es fundamental para asegurar el mejor actuar posible en casos similares en reumatología.(AU)

Background and objective: Termination of pregnancy in patients with rheumatic diseases is controversial and a bioethical analysis is rarely performed. In this study we analysed the case of a pregnant patient with lupus nephritis unresponsive to treatment, for whom termination of pregnancy is considered. Methods: The integrative model was applied combining different normative ethical theories. Results: From a utilitarian perspective, termination of pregnancy is justifiable, seeking the greatest benefit for the greatest number of stakeholders. Deontology justifies both terminating and continuing the pregnancy, focusing on the action itself and on autonomy. In virtue ethics the importance of decisions rests with the person who performs the action seeking flourishing; termination of pregnancy would be justifiable. Discussion and conclusions: Interruption of pregnancy is a justifiable solution following the integrative model. Bioethical analysis of paradigmatic cases is essential to ensure the best possible action and as a precedent for future similar situations in rheumatology.(AU)

The Memory Alteration Test Is Correlated with Clinical, Cerebrospinal Fluid, and Brain Imaging Markers of Alzheimer Disease in Lima, Peru.

INTRODUCTION: As disease-modifying therapies become available for Alzheimer's disease (AD), detection of AD in early stages of illness (mild cognitive impairment [MCI], early dementia) becomes increasingly important. Biomarkers for AD in low- and middle-income countries (LMICs) are costly and not widely available; hence, it is important to identify cognitive tests that correlate well with AD biomarker status. In this study, we evaluated the memory alteration test (M@T) to detect biomarker-proven AD and quantify its correlation with neurodegeneration and cerebrospinal fluid (CSF) AD biomarkers in a cohort of participants from Lima, Peru. METHODS: This is a secondary analysis of a cohort of 185 participants: 63 controls, 53 with amnestic MCI (aMCI), and 69 with dementia due to AD. Participants underwent testing with M@T and a gold standard neuropsychological battery. We measured total tau (t-tau), phosphorylated tau (p-tau), and beta-amyloid (ß-amyloid) in CSF, and evaluated neurodegeneration via medial temporal atrophy score in MRI. We used receiver-operator curves to determine the discriminative capacity of the total M@T score and its subdomains. We used the Pearson coefficient to correlate M@T score and CSF biomarkers. RESULTS: The M@T had an area under the curve (AUC) of 0.994 to discriminate between controls and cognitively impaired (aMCI or AD) patients, and an AUC of 0.98 to differentiate between aMCI and AD patients. Free-recall and cued recall had the highest AUCs of all subdomains. Total score was strongly correlated with t-tau (-0.77) and p-tau (-0.72), and moderately correlated with ß-amyloid (0.66). The AUC for discrimination of neurodegeneration was 0.87. CONCLUSION: The M@T had excellent discrimination of aMCI and dementia due to AD. It was strongly correlated with CSF biomarkers and had good discrimination of neurodegeneration. In LMICs, the M@T may be a cost-effective screening tool for aMCI and dementia caused by AD.

La seguridad social en salud: situación y posibilidades / Social security in health: situation and possibilities

La reforma de seguridad social en salud fue llevada a cabo a partir de 1997, pero es recién en los años posteriores cuando se implementan los primeros cambios, definiéndose un esquema mixto donde las Entidades Prestadoras de Salud (EPS) juegan un rol complementario al Seguro Social. Presenta una síntesis del nuevo marco institucional, a la vez que realiza un análisis de la situación
