Actuales retos diagnósticos genómicos en los Síndromes Hemofagocíticos en pediatría: reporte de caso

Introducción: La linfohistiocitosis hemofagocítica familiar (FHL) es una enfermedad del sistema autoinmune que se presenta con un síndrome inflamatorio excesivo causado por linfocitos T activados e histiocitosis. Cursa con herencia autosómica recesiva ligada al cromosoma X. Aproximadamente el 90% de los niños diagnosticados son menores de 2 años y la incidencia es de aproximadamente 0.12 por 100.000. Se puede dividir en cinco subtipos según la variante genética causante. Las variantes patogénicas más involucradas son en los genes de la perforina 1 (PRF1) y homólogo D de la proteína UNC-13 (UNC13D). Caso clínico: Se presenta el caso de un preadolescente de 11 años, con antecedente de infecciones recurrentes, quien cursa con síndrome convulsivo asociado a fiebre, peso y talla bajas para la edad, hepatomegalia y discapacidad cognitiva. En el abordaje inicial se descartan enfermedades infecciosas, inmunológicas, hematológicas, metabólicas y oncológicas. El exoma clínico para inmunodeficiencias primarias muestra una variante patogénica p.A91V homocigota en el gen de la PRF1 de herencia autosómica recesiva, resultado relacionado con linfohistiocitosis hemofagocítica familiar tipo 2 (FHL2). Discusión y conclusión: El cambio conformacional del PRF1 alterado reduce la actividad citotóxica de la proteína y provoca la enfermedad. Los pacientes portadores de defectos en el gen PRF1 son vulnerables a infecciones, enfermedades autoinmunes y tumores malignos. Con un diagnóstico definido y preciso es posible orientar las acciones en salud, pautas de seguimiento, evaluación de riesgo de heredabilidad a través de un caso índice para así encontrar otros posibles portadores, realizar un asesoramiento genético completo, implementar e iniciar tratamientos dirigidos que aminoren la morbilidad y mortalidad asociada a esta patología. Actualmente se cuenta con varios estudios en diferentes fases de investigación sobre moléculas que pueden intervenir en la historia natural de la enfermedad. (provisto por Infomedic International)

Introduction: Familial hemophagocytic lymphohistiocytosis (FHL) is a disease of the autoimmune system that presents with an excessive inflammatory syndrome caused by activated T lymphocytes and histiocytosis. It occurs with autosomal recessive inheritance linked to the chromosome X. Approximately 90% of diagnosed children are under 2 years of age and the incidence is approximately 0.12 per 100,000. It can be divided into five subtypes depending on the causative genetic variant. The most involved pathogenic variants are in the perforin 1 (PRF1) and UNC-13 protein homolog D (UNC13D) genes. Clinical case: The case of an 11-year-old preadolescent is presented, with a history of recurrent infections, who presents with convulsive syndrome associated with fever, low weight and height for age, hepatomegaly and cognitive disability. In the initial approach, infectious, immunological, hematological, metabolic and oncological diseases are ruled out. The clinical exome for primary immunodeficiencies shows a homozygous pathogenic variant p.A91V in the PRF1 gene of autosomal recessive inheritance, a result related to familial hemophagocytic lymphohistiocytosis type 2 (FHL2). Discussion and conclusion: The altered PRF1 conformational change reduces the cytotoxic activity of the protein and causes disease. Patients carrying defects in the PRF1 gene are vulnerable to infections, autoimmune diseases and malignant tumors. With a defined and precise diagnosis, it is possible to guide health actions, follow-up guidelines, evaluation of heritability risk through an index case in order to find other possible carriers, carry out complete genetic counseling, implement and initiate targeted treatments that reduce the morbidity and mortality associated with this pathology. Currently, there are several studies in different phases of research on molecules that may intervene in the natural history of the disease. (provided by Infomedic International)

Abstract To evaluate the accuracy of complete arch scanning with multiple implant titanium scan bodies using laboratory scanners. A master model of an edentulous maxillary arch with 6 implants was fabricated. Titanium scan bodies were inserted into the model. Three laboratory scanners were used: D2000 (3Shape), Vinyl High Resolution (Smart Optics), and inEos X5 (Dentsply Sirona). The master model was consecutively scanned ten times using dental laboratory scanners (LS) without detaching and repositioning the scan bodies. Linear and angular accuracy between adjacent implants was measured using inspection software (Control X, Geomagic). The accuracy of the complete arch scans was calculated. Implant regions were defined as; parallel (R1: #24-26 and #16-14), angled (R2: #22-24 and #14-12), angled to occlusal plane (R3: #12-22), and cross-arch (R4: #16-26). The effect of LS and implant region on accuracy was compared using two-Way ANOVA (α=0.05). Significant greater linear distortion was noted in R4 (61.2±17.9µm) compared to R1 (23.4±15.5µm) and R2 (26±17.7µm) (p<0.01). Greater linear distortions were noted in R4 with D2000 (0.07±0.016 degrees) and Vinyl High Resolution (0.067±0.02 degrees) than inEos X5 (0.032±0.021 degrees) (p>0.05). Greater mean linear precisions were noted in R1 (9±8µm) and R3 (9.3±8.3µm) than R4 (12.6±10.3µm) (p<0.05). The highest linear precision was noted in D2000 (7.2±7.6µm) (p<0.05). The angular precision of D2000 (0.02±0.015 degrees) was the highest (p<0.01). The angular precisión of R4 (0.036±0.018 degrees) was the lowest (p<0.01). This study revealed that the trueness was affected by the implant region and the precision was affected by both LS and implant region.

La genética de la epilepsia en la práctica clínica / The genetics of epilepsy in the clinical practice

Resumen La epilepsia es un trastorno neurológico caracterizado por crisis epilépticas recurrentes no provocadas, en el cual la genética tiene un factor etiológico importante. Durante las últimas décadas se ha logrado encontrar genes específicos involucrados en la patogénesis de esta condición. Actualmente existen múltiples exámenes disponibles en la práctica clínica para el diagnóstico genético, siendo los más útiles los paneles multi-genes y la secuenciación del exoma completo por medio de next generation sequencing (NGS). El tener un diagnósti co genético puede mejorar la calidad de vida de cada paciente y su familia, al mismo tiempo que nos ayuda a individualizar el tratamiento haciéndolo más eficaz. Algunos ejemplos en los que el diagnóstico genético puede modificar la conducta terapéutica incluyen el gen SCN1A en que se recomienda no utilizar medicamentos bloqueadores de canales de sodio y el gen SLC2A1 en el que se recomienda el inicio de la dieta cetogénica. El futuro de la investigación en medicina de precisión en epilepsia es muy prometedor, con el objetivo de que cada paciente reciba un tratamiento acorde a su etio logía genética.

Abstract Epilepsy is a neurological disorder characterized by recurrent unprovoked seizures. It is known that genetics play an important etiology roll. During the last decades it has been possible to find specific genes involved in the pathogenesis of this condition. There are currently multiple studies available in clinical practice for genetic diagnosis, the most useful being the next generation se quencing (NGS) techniques with multi-gene panels and whole exome sequencing. Having a genetic diagnosis can help improve the quality of life of each patient and their family, while it helps us to individualize the treatment, making it more effective. Some examples in which ge netic diagnosis can modify therapeutic conduct include the SCN1A gene, in which it is recommended not to use drugs that block Sodium channels, and the SLC2A1 gene, in which starting ketogenic diet is recommended. The future of precision medicine research in epilepsy is very promising, with the goal that each patient receives treatment according to their genetic etiology.

Effect of Soil and Climatic Conditions on Brown Spot Occurrence in Rice Lowland across Four Agro-climatic Zones of Côte d’Ivoire

Aims: To evaluate interaction of soil pH and acidity with weather on Rice Brown spot (BS) occurrence in rice lowlands. Study Design: Cross sectional study. Place and Duration of Study: Four distinct rice lowlands belonging to different climatic zones (forest, transitional and savanna) of Côte d’Ivoire during cropping seasons of 2021. Methodology: BS characterization were done in different farmer fields where soil samples were also collected during dry and rainy seasons. Soil silicon and acidity were determined in those samples and rice grain yield at harvest time were recorded in different sites. Weather data related to sites and seasons were used to find out correlations. Results: Occurrence of BS was found in forest zones with scores of 4 and 3 compared to 1 and 2 in savanna and transitional zones, respectively, with seasonal variation. Both rice production and the occurrence of BS were explained by soil parameters in conjunction with climatic parameters. Rainfall (R=0.38) and relative humidity (R=0.64) leaded BS occurrence and decrease of yield. Wind speed (R=0.62) and air maximum temperature (R= 0.63) were the determinant factors affecting rice yields. Si was found to be a component of sustainable soil management that interferes with soil pH in all climatic zones. Combined with Temperature, both soil parameters predicted BS occurrence over 50%. Conclusion: Temperature decrease BS pathogens occurrence whereas high humidity increases its spread. Those parameters combined with silicon which interferes with pH could leads sustainable solutions in BS control. Furthermore, having a deep understanding with rice varietal considerations can significantly improve strategies related to rice cultivation and protection.

Research progress on genome-guided precision oncology and development ideas of antitumor Chinese medicine / 中国中药杂志

Genome-guided oncology refers to a new treatment concept that transcends histological classification and pathological ty-ping and uses drugs according to the genetic characteristics of tumors. New drug development technology and clinical trial design based on this concept provide new ideas for the clinical application of precision oncology. The multi-component and multi-target characteristics of Chinese medicine provide rich resources for the development of tumor-targeting drugs from natural products, and the design of the master protocol trial aiming at the characteristics of precision oncology supports the rapid clinical screening of effective tumor-targeting drugs. The emergence of the synthetic lethality strategy breaks through the bottleneck that the drug can only target the oncogene but cannot do anything to the tumor suppressor gene with the loss-of-function mutation in the past. With the rapid development of high-throughput sequencing technology, the cost of sequencing is also decreasing. For the development of tumor-targeting drugs, how to keep up with the update speed of target information is a difficult problem of concern. Based on the integration of innovative ideas and me-thods of precision oncology, network pharmacology, and synthetic lethality strategy on synthetic lethal interaction network of antitumor Chinese medicine compatibility formula design, and the combination of improvement of innovative clinical trial methods, such as master protocol trial, basket trial, and umbrella trial, unique advantages of Chinese medicine are expected to be exerted beyond the antibody-based drugs and small molecule-based drugs and corresponding targeted drugs are potentially developed for clinical application.

Tensor decomposition: new strategy for deciphering mechanism of precision medicine for same treatment of different diseases / 中国中药杂志

The aging society has led to a substantial increase in the number of clinical comorbidities. To meet the needs of comorbidity treatment, polypharmacy is widely used in clinical practice. However, polypharmacy has drawbacks such as treatment conflict. Same treatment of different diseases refers to treating different diseases with same treatment. Therefore, the principle of same treatment of different diseases can alleviate the problems caused by polypharmacy. Under the research background of precision medicine, it becomes possible to explore the mechanism of same treatment of different diseases and achieve its clinical application. However, drugs successfully developed in the past have revealed shortcomings in clinical use. To better interpret the mechanism of precision medicine for same treatment of different diseases, under the multi-dimensional attributes including dynamic space and time, omics was performed, and a new strategy of tensor decomposition was proposed. With the characteristics of complete data, tensor decomposition is advantageous in data mining and can fully grasp the connotation of precision treatment of different diseases with same treatment under dynamic spatiotemporal changes. This method is used for drug repositioning in some biocomputations. By taking advantage of the dimensionality reduction of tensor decomposition and integrating the dual influences of time and space, this study achieved accurate target prediction of same treatment of different diseases at each stage, and discovered the mechanism of precision medicine of same treatment for different diseases, providing scientific support for precision prescription and treatment of different diseases with same treatment in clinical practice. This study thus conducted preliminary exploration of the pharmacological mechanism of precision Chinese medicine treatment.

Medicine+information: Exploring patent applications in precision therapy in cardiac surgery / 中国胸心血管外科临床杂志

@#Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.

Umbrella trial for clinical trial design of oncology drugs / 中国胸心血管外科临床杂志

@#The umbrella trial has received increasing attention in the design of clinical trials for oncology drugs in recent years. This trial design categorizes a single disease into multiple sub-types based on predictive biomarkers or other predictive factors, and simultaneously evaluates the efficacy of multiple targeted therapies. When compared with the traditional drug development model of phase Ⅰ, phaseⅡ, and phase Ⅲ randomized controlled trials, umbrella trials are a more scientifically rigorous trial design that can speed up drug evaluation to address the conflict between numerous untested drugs and diseases with a lack of effective treatment options. This article will focus on the concept, main characteristics, eligibility criteria, design and statistical considerations, ethical considerations, and future directions of umbrella trials, with the aim of providing methodological guidance for the design of clinical trials for oncology drugs.

Selective mediastinal lymph node dissection: Precision surgery in the era of precision medicine / 中国胸心血管外科临床杂志

@#Along with the popularity of low-dose computed tomography lung cancer screening, an increasing number of early-stage lung cancers are detected. Radical lobectomy with systematic nodal dissection (SND) remains the standard-of-care for operable lung cancer patients. However, whether SND should be performed on non-metastatic lymph nodes remains controversy. Unnecessary lymph node dissection can increase the difficulty of surgery while also causing additional surgical damage. In addition, non-metastatic lymph nodes have been recently reported to play a key role in immunotherapy. How to reduce the surgical damage of mediastinal lymph node dissection for early-stage lung cancer patients is pivotal for modern concept of "minimally invasive surgery for lung cancer 3.0". The selective mediastinal lymph node dissection strategy aims to dissect lymph nodes with tumor metastasis while preserving normal mediastinal lymph nodes. Previous studies have shown that combination of specific tumor segment site, radiology and intraoperative frozen pathology characteristics can accurately predict the pattern of mediastinal lymph node metastasis. The personalized selective mediastinal lymph node dissection strategy formed from this has been successfully validated in a recent prospective clinical trial, providing an important basis for early-stage lung cancer patients to receive more personalized selective lymph node dissection with "precision surgery" strategies.
