Title translation	Rare diseases and undiagnosed diseases: advances in neurodevelopment.
Abstract	Rare diseases and undiagnosed diseases have recently positioned themselves as clinical entities that provide important opportunities to advance our understanding of gene functions and the impact of them in the individual development. In this review, we present how efforts made over years to understand common diseases, rare diseases and even undiagnosed diseases come together today to cooperatively advances scientific knowledge. These advance in science and new acquired knowledge, make possible to apply the advances obtained in a group of clinical conditions to others with similar phenotypic characteristics or vice versa. The cooperative work of multidisciplinary teams and the communication between clinicians and researchers have and will provide opportunities for better treatments for patients and families across multiple common and rare diseases.

Title translation	Neurodevelopmental disorders: from the laboratory to the classroom.
Abstract	Neurodevelopmental disorders are the most common diagnosis in the clinical practice in child neurology. Since the 70's the terminology used for the diagnosis of these conditions, was developed with the goal of obtaining better services for those individuals affected. Over the years the classification has changed but the fundamental process for diagnosis continues the same. There is a new movement aiming to change the current classification and propose a new one based in the molecular deficits associated with the clinical phenotype rather than a collection of symptoms. This new approach focusses on the identification of the molecular defectcausing of the specific to design targeted interventions that will promise a curative approach, rather than the current symptom-based interventions available. Important progress has been done alrea dy, given the high association between cognitive/compartmental phenotype in some well-known genetic defects like Neurofibromatosis, TSC, Down syndrome, and the high association between different cognitive/compartmental phenotype in rare diseases. The future will hold opportunities to properly identify the molecular deficit and a tailored intervention for those conditions today called Neurodevelopmental disabilities.

Title translation	Sleep, memory and learning.
Abstract	Recent studies have demonstrated that while we are sleeping, our brain is very busy processing all information we have acquired along the day. Lack of sleep has shown to produce deficits in memory consolidation and plays an important role in brain development and brain plasticity in the several developmental stages of the human brain. At the cellular level, circadian cycles coordinate complex mechanism that "turn on and off" genes and cellular structures regulating individual cell functions to impact global organ and systems physiological activities. At the end a perfect and coordinated equilibrium in the mental, emotional and physiological is the goal of this complex process. Sleep impacts memory, learning, mood, behavior, immunological responses, metabolism, hormone levels, digestive process and many more physiological functions. We present a review of three basic aspects related with sleep: a. brain electrical activity during the sleep and neuroanatomic correlation with mechanism related with memory and learning; b. circadian cycles and impact in several physiological systems; c some examples of clinical disorders associated with sleep disorders and impact in learning and memory.

Abstract	Hybridization is a common and widespread phenomenon in vascular plants, leading to genetic exchange between related species. Interspecific hybridization has been extensively reported in Prosopis, a key genus of the Gran Chaco Americano, when species grow in sympatry or have adjacent distributions. Here, we performed a cytogenetic study in a hybrid zone of Prosopis alba, P. hassleri, and P. fiebrigii in southern South America. We characterized the karyotypes of pure species and the putative interspecific hybrids using chromosome fluorescent banding. Two karyotypes according to the heterochromatin pattern were identified, one corresponding to P. alba and the other to P. hassleri and P. fiebrigii; hybrid individuals presented P. alba or P. hassleri/P. fiebrigii karyotypes. The karyotypic formula and the number of nucleolar organizer regions were the same for all the studied morphotypes. Chromosome similarity among different species of the genus allows a continued hybridization and introgression between species and lends support to the hypothesis of a relatively recent diversification of Prosopis. Studying karyotype variation within a population could be a novel approach to the cytogenetic study of hybrids in the future.

Title translation	Attention deficit hyperactivity disorder beyond adolescence. Time to think different?
Abstract	ADHD is a neurodevelopmental disorder characterized by a pattern of severe inattention-disorganization and/or hyperactivity-impulsivity beyond what is expected for individuals with a comparable development level. These behaviors impair daily life activities of patients in more than one environment and impact their performance and abilities compared with their peers. Extensive reviews have been published about the psychiatric comorbidities associated with ADHD but little attention has been given to the overall impact of ADHD on health. This study reviews some of the most common problems in medical care associated with ADHD like smoking, substance use, accident risk, sleep disorders, obesity, hypertension, diabetes, and early mortality. Today, a close follow-up of patient with ADHD is necessary not only from the psychiatric perspective but also in regard to general medicine issues to prevent the impact on health of those medical co-morbidities. Such conditions can end in severe chronic diseases with consequences and high cost for the individuals, the families and the society far beyond the academic and emotional impact frequently described as associated to ADHD. This condition has serious repercussions on health which need a medical multidisciplinary approach.

Abstract	Introduction: Childhood dietary behaviors, including fruit and vegetable intake, are associated with adult health. Most children do not meet daily recommended servings of fruits and vegetables. Less is known about temporal patterns in fruit and vegetable consumption or if they vary by race and ethnicity. We investigated temporal patterns in fruit and vegetable intake among California school-age children and adolescents overall and by race and ethnicity. Methods: We used 2-year cross-sectional datasets from the child and adolescent samples in the California Health Interview Surveys from 2011-2012 through 2019-2020 and modified Poisson regression models to estimate the likelihood of consuming 5 or more servings of fruits and vegetables in 2013-2016 and 2017-2020 compared with 2011-2012. Models controlled for age, race and ethnicity, gender, citizenship status, family income, and adult education and tested for differences by race and ethnicity. The samples included 16,125 children aged 5 to 11 years and 9,672 adolescents aged 12 to 17 years. Results: Overall, 29.3% of children and 25.9% of adolescents reported intake of 5 or more fruits and vegetables per day. Among children, adjusted prevalence ratios (PR) of fruit and vegetable intake were higher in 2013-2016 (PR,1.25; 95% CI, 1.11-1.42) and 2017-2020 (PR,1.13; 95% CI, 0.99-1.30) compared with 2011-2012. Among adolescents, the adjusted prevalence did not differ significantly over time. We found no evidence of differential associations by race and ethnicity for children and adolescents. Conclusion: We found favorable temporal changes in fruit and vegetable consumption among children, but not among adolescents. Monitoring temporal patterns in fruit and vegetable intake remains critical for planning population-level interventions to increase consumption.

Abstract	Diatoms play a key role in the marine silica cycle, but recent studies have shown that sponges can also have an important effect on this dynamic. They accumulate large stocks of biogenic silica within their bodies over long periods, which are thought to vary little on an intra-annual scale. The observation of an abrupt decline in sponge biomass in parallel with large increases in abundance of a spongivorous nudibranch (Doris verrucosa) led us to conduct a year-long study on the effect of nudibranch predation on the silicon budget of a sponge (Hymeniacidon perlevis) population. After 5 months of predation, the abundance of sponge individuals did not change but their biomass decreased by 95%, of which 48% was explained by nudibranch predation. About 97% of sponge spicules ingested by nudibranchs while feeding was excreted, most of them unbroken, implying a high rate of sponge silica deposition in the surrounding sediments. After predation, sponges partially recovered their biomass stocks within 7 months. This involved a rapid growth rate and large assimilation of dissolved silicon. Surprisingly, the highest rates of silicon absorption occurred when dissolved silicon concentration in seawater was minimal (< 1.5 µM). These findings suggest that the annual sponge predation-recovery cycle triggers unprecedented intra-annual changes in sponge silicon stocks and boosts the cycling of this nutrient. They also highlight the need for intra-annual data collection to understand the dynamics and resilience of sponge ecosystem functioning.

Abstract	This review summarizes and discusses the knowledge of cytogenetics in Solanaceae, the tomato family, its current applications, and prospects for making progress in fundamental systematic botany and plant evolution. We compile information on basic chromosome features (number, size, morphology) and molecular cytogenetics (chromosome banding and rDNA patterns). These data were mapped onto the Solanaceae family tree to better visualize the changes in chromosome features and evaluate them in a phylogenetic context. We conclude that chromosomal features are important in understanding the evolution of the family, especially in delimiting clades, and therefore it is necessary to continue producing this type of data. The potential for future applications in plant biology is outlined. Finally, we provide insights into understanding the mechanisms underlying Solanaceae's diversification that could substantially contribute to developing new approaches for future research.

Abstract	Background: Knowledge of severe malaria (SM) or complicated malaria is insufficient in all its components. The least known type is the one associated with Methods: A descriptive, retrospective, and cross-sectional study of secondary information was performed via SIVIGILA. Results: There were 9881 SM cases among 1,060,950 total malaria cases in Colombia in 2007-2020: 9.31 SM cases per 1000 malaria cases. During this period, there were 7145 SM cases due to the following species: Conclusions: There has been a reduction in malaria incidence in Colombia in the last 10-15 years, but there has also been a strong increase in SM incidence. We suggest emphasizing the prevention of the onset of severe malaria, with the early and accurate diagnosis of plasmodial infection.

Abstract	Colonic varices are a rare condition primarily caused by portal hypertension associated with conditions such as cirrhosis or hepatocellular carcinoma. Idiopathic cases are even rarer, with less than 50 cases with a pan-colonic affection reported in the literature. Males are more commonly affected, with an average age of 41 years. Colonic varices can involve the entire colon in idiopathic cases and are often familial. Gastrointestinal bleeding is the main symptom, ranging from mild to life-threatening. Diagnosis is typically made through colonoscopy, which reveals dilated bluish vascular tracts. Treatment involves fluid IV resuscitation and controlling hemorrhage through various methods such as endoscopic procedures. Correction of the underlying cause is essential in cases of portal hypertension. Recurrent or unstable cases may require colon resection. On this occasion, we present the case of a female patient who experienced profuse lower gastrointestinal bleeding. The patient's colonoscopy revealed the presence of varices throughout the entire length of the colon, with the only recent bleeding site being in the hemorrhoidal tissue. Therefore, a hemorrhoidectomy was performed to carry out an effective and less invasive therapeutic procedure than a colectomy with an excellent postoperative evolution.
