RESUMO
Background: Multisystemic inflammatory syndrome in children (MIS-C) is one of the most severe presentations of COVID-19 infection in pediatrics. Currently, we have few studies that describe the characteristics of this condition in Colombian children. Objective: To describe the clinical and epidemiological characteristics of children hospitalized with MIS-C in Neiva, Colombia. Methods: Observational follow-up study of a cohort of children with MIS-C for 12 months (May 15, 2020, to May 30, 2021) in two hospitals in the city of Neiva. Epidemiological data, clinical characteristics, laboratory characteristics, cardiological evaluation, treatment, and clinical outcomes were analyzed. Results: We included 34 patients who met the diagnosis of MIS-C. The median age was 68 months. Some type of nutritional issue was observed by 43.75% of those under 5 years of age and by 27.78% of those over 5 years of age. Gastrointestinal symptoms were the most frequent, with vomiting, diarrhea, and abdominal pain being the most frequent by 79, 70, and 67%, respectively. By 77% of the patients, a history of SARS-COV-2 infection was documented through IgG. In the echocardiogram, 35.4% of the patients had systolic dysfunction, followed by coronary involvement by 35%. Conclusion: This study describes a series of cases of children with MIS-C in Colombia. Gastrointestinal manifestations were predominant. Mortality was high in comparison to other countries but similar to that reported in Colombia. This fact was associated with relevant pathological background. More training is required for physicians in order to have a better understanding of the disease so as to have an early diagnosis and timely treatment.
RESUMO
SUMMARY: Multisystemic inflammatory syndrome (MIS-C) can develop as a complication of SARS CoV-2 infection, involving the gastrointestinal system mainly by vasoconstriction, edema, glandular hyperplasia, and a procoagulant state leading to direct tissue injury. METHOD: ology: a series of cases including 8 patients with MIS-C treated in two highly complex institutions is presented. These patients, had abdominal symptoms of surgical management. RESULTS: The average age was 9.5 years and the most frequent symptoms were fever, abdominal pain, diarrhea (100%); in addition, 87.5% presented shock. The diagnosis of SARS CoV-2 was confirmed by RT-PCR test in 37.5%, antigen 12.5% and the rest of the patients showed IgM and IgG antibodies. In laboratories, the increase in acute phase reactants, Erythrocyte Sedimentation Rate (ESR), C-reactive protein, procalcitonin, as well as troponin, D dimer and proBNP, is highlighted. The surgical outcome documented 2 patients with a normal appendix, 3 patients with edematous appendicitis, and 3 patients with complicated appendicitis. CONCLUSIONS: patients with MIS-C display abdominal symptoms similar to those present in surgical emergencies and a non-negligible number of cases require surgical exploration. This condition poses a new differential diagnosis to the surgical abdomen in pediatric patients.
RESUMO
Abstract Introduction: dental fluorosis is the hypomineralization of enamel produced as a result of fluoride intake for a prolonged period during enamel formation. The aim of the present study was to identify the factors associated with dental fluorosis in children and teenagers from the city of Montería, Colombia. Methods: a quantitative, descriptive and retrospective study was conducted in a sample of 136 dental fluorosis cases in schoolchildren aged 6, 12, 15 and 18 years reported to the Surveillance and Control System from January to December 2016. Results: there was fluoride exposure in 81.6% of schoolchildren covered by the subsidized health system-the mechanism by which the poorest population, with not enough resources to pay, can access health services through a subsidy offered by the state in Colombia-. 89% were from the municipal center, defined by Colombia's National Administrative Department of Statistics (Departamento Administrativo Nacional de Estadística, DANE) as the geographical area bounded by an urban perimeter, where the administrative headquarters of a municipality are located. 47% of patients had cavities. Tooth brushing in a frequency higher than three times a day was predominant with 48.5%, and the use of toothpaste on more than 3/4 of the brush with 52%. 71.3% of patients said they did not swallow toothpaste, and 93.4% did not swallow mouthwash. 82.4% of patients did not receive topical fluoride in the last year. Conclusions: several factors are more highly associated with dental fluorosis, such as the amount of toothpaste during brushing, the habit of brushing three or more times a day, consumption of diet salt, and unintentional intake of toothpaste at an early age. Most schoolchildren had a moderate degree of dental fluorosis.
Resumen Introducción: la fluorosis dental es una hipomineralización del esmalte, producida como respuesta a la ingesta de flúor por un periodo prolongado de tiempo durante la formación del esmalte. El objetivo del presente studio consistió en determinar los factores asociados a la fluorosis dental en niños y jóvenes de la ciudad de Montería. Métodos: se realizó una investigación descriptiva retrospectiva cuantitativa, con una muestra conformada por 136 casos de fluorosis dental en escolares de 6, 12, 15 y 18 años notificados al sistema de vigilancia y control, en el periodo de enero a diciembre de 2016. Resultados: se presentaron 81,6% casos de escolares con exposición a flúor pertenecientes al régimen subsidiado, que es el mecanismo mediante el cual la población más pobre, sin capacidad de pago, tiene acceso a los servicios de salud mediante un subsidio ofrecido por el Estado colombiano; el 89% eran procedentes de la cabecera municipal, definida por el Departamento Administrativo Nacional de Estadísticas (DANE) en Colombia como el área geográfica delimitada por un perímetro urbano, donde se ubica la sede administrativa de un municipio. El 47% de los pacientes presentaron caries. La frecuencia de cepillado mayor a tres veces al día fue predominante en 48,5% y el uso de crema dental en más de 3/4 del cepillo en el 52%. El 71,3% de los pacientes manifestaron que no ingerían crema dental, ni enjuague bucal en un 93,4%. Un 82,4% de los pacientes no recibieron topificación de flúor en el último año. Conclusiones: existen factores con mayor fuerza de asociación con fluorosis dental, como la cantidad de dentífrico en el cepillado, frecuencia del cepillado entre tres o más veces al día, consumo de sal en dieta e ingesta accidental de dentífrico a temprana edad. La mayoría de los escolares presentó grado moderado de severidad de fluorosis dental.

Resumen Introducción. Las inmunodeficiencias primarias son enfermedades genéticas del sistema inmune que incrementan la susceptibilidad a infecciones. Una de las formas más graves en niños es la inmunodeficiencia combinada severa. Presentación del caso. Se presenta el caso de un niño que fue diagnosticado con inmunodeficiencia combinada severa; este era un paciente masculino de ocho meses que presentó cuadro clínico consistente en múltiples hospitalizaciones debido a infección por citomegalovirus, endocarditis por Candida albicans e infección recurrente de las vías urinarias por Pseudomonas aeruginosa. El perfil inmunológico mostró disminución del número absoluto de células CD3+ y CD19+, lo que permitió realizar el diagnóstico de inmunodeficiencia combinada severa instaurándose manejo; sin embargo, el niño no se recuperó y falleció. Conclusiones. Las inmunodeficiencias primarias son patologías que requieren una intervención oportuna que permita brindar un mejor pronóstico a los pacientes.
Abstract Introduction: Primary immunodeficiencies are genetic disorders of the immune system that increase susceptibility to infections. One of the most serious forms in children is severe combined immunodeficiency. Case presentation: This is the report of the case of an 8-monthold male patient who was diagnosed with severe combined immunodeficiency. The child presented a clinical profile consisting of multiple hospitalizations due to cytomegalovirus infection, endocarditis by Candida albicans and recurrent urinary tract infection by Pseudomonas aeruginosa. The immune profile showed a decrease in the absolute number of CD3+ and CD19+ cells, which led to the diagnosis of severe combined immunodeficiency. Even though management was established, the child did not recover and died. Conclusions: The primary immunodeficiencies are disorders that require timely intervention to provide a better prognosis to patients.
RESUMO
In aquaculture, fighting infectious diseases is a necessity. This study measured the immuno-stimulating effect of live macroalgae consumption on Litopenaeus vannamei against Vibrio parahaemolyticus and WSSV infection in two independent bioassays. Shrimps and macroalgae were cultivated in a co-culture with two species of macroalgae separately (Gracilaria vermiculophylla and Dictyota dichotoma), and later, shrimp were infected with V. parahaemolyticus. In another bioassay, shrimp and macroalgae (G. vermiculophylla, D. dichotoma and Ulva lactuca) were grown and subsequently infected with WSSV. For both bioassays, survival after 120â¯h was determined, the total hemocyte count (TCH) was measured and the activity of superoxide dismutase (SOD) and catalase (CAT) in tissue were measured. The results indicate that the use of macroalgae in co-culture with L. vannamei provides a nutritional benefit that achieves higher growth than the control organisms, as well as improvements of the ammonium concentration and immune response after infection with V. parahaemolyticus and WSSV. A better immune response was obtained in organisms cultured with macroalgae in both bioassays at a ratio of 1.6-1.9 for organisms infected with bacteria and 1.4 to 1.6 times for organisms infected with the virus. In turn, the enzymatic activity of SOD and CAT were higher in the treated organisms relative to the controls in both experiments.

Introducción. La neonatología del Hospital de los Valles (HDLV) es un centro de referencia de cuarto nivel con atención de pacientes prematuros que presentan un mayor riesgo de morbimortalidad y en quienes aún hay debate sobre la edad gestacional aceptable para aunar esfuerzos en tratamiento y sobrevida. En los Estados Unidos, la tasa de nacimientos prematuros, que había aumentado constantemente durante la década de 1990 y principios de 2000, ha disminuido anualmente durante 7 años y ahora es aproximadamente del 11,39%. La viabilidad humana, definida como la edad gestacional en la que la posibilidad de supervivencia es del 50%, actualmente es de aproximadamente 23 a 24 semanas en los países desarrollados, con una supervivencia de prematuros de 25 semanas superior al 60%. Materiales y Métodos. Es un estudio descriptivo transversal de tipo retrospectivo, en el que se tomó como población a todos los niños nacidos antes de las 28 semanas de gestación atendidos en el Hospital de los Valles desde enero del 2014 a diciembre del 2018, se obtuvieron los datos de la base de datos EpicLatino y de las historias clínicas de los pacientes, Los datos obtenidos fueron ingresados en el programa Excel para su tabulación y análisis. Resultados. Entre enero del 2014 a diciembre del 2018 se registraron 1710 pacientes de los cuales 479 son prematuros y de estos 29 son prematuros extremos. Se registraron 8 fallecimientos 5 de los cuales nacieron fuera de la institución, la edad gestacional más temprana con sobrevida es de 24.5 semanas y el menor peso registrado es de 575 gramos, la morbilidad más comúnmente asociada a la prematurez extrema en orden descendente es enfermedad de membrana hialina, anemia, sepsis y broncodisplasia pulmonar, no hay registro de retinopatía y se reportaron 6 casos de hemorragia intraventricular. El peso promedio de alta es de 2045 gramos, con 16 pacientes enviados a casa con oxigeno domiciliario. Conclusión. La neonatología del HDLV presta atención de cuarto nivel con una sobrevida en pacientes menores de 28 semanas de edad gestacional comparable con otras instituciones a nivel mundial, con una mejor respuesta en pacientes nacidos dentro de la propia institución, es importante que los pacientes que tengan riesgo de nacer a edades gestacionales muy cortas sean derivados oportunamente a instituciones con mayor capacidad resolutiva en bien del paciente y su familia.
is an increased risk of morbidity and mortality and in whom there is still debate about the acceptable gestational age to combine efforts in treatment and survival. In the United States, the rate of premature births, which had steadily increased during the 1990s and early 2000s, has decreased annually for 7 years and now is approximately 11.39%. Human viability, defined as gestational age in which the possibility of survival is 50%, currently is approximately 23 to 24 weeks in developed countries, with a survival of preterm infants of 25 weeks greater than 60% . Materials and methods. This is a cross-sectional, retrospective descriptive study, in which all children born before the 28 weeks of gestation attended at the Hospital de los Valles from January 2014 to December 2018 were taken as a population. EpicLatino database and the patient's medical records. The data obtained were entered into the Excel program for tabulation and analysis. Results Between January 2014 and December 2018, 1710 patients were registered, of whom 479 are premature and of these 29 are premature preterm infants. There were 8 deaths 5 of which were born out of the institution, the earliest gestational age with survival is 24.5 weeks and the lowest recorded weight is 575 grams, the morbidity most commonly associated with extreme prematurity in descending order is disease. hyaline membrane, anemia, sepsis and pulmonary bronchodysplasia, there is no record of retinopathy and 6 cases of intraventricular hemorrhage were reported. The average dischange weight is 2045 grams, with 16 patients sent home with home oxygen. Conclusion. HDLV neonatology provides fourth level care with a survival in patients younger than 28 weeks gestational age comparable with other institutions worldwide, with a better response in patients born within the institution itself, it is important that patients at risk of being born at very short gestational ages are opportunely referred to institutions with greater resolutive capacity for the good of the patient and his family.

Abstract Introduction: Dengue can compromise organs such as the myocardium and the liver. Clinical evolution may be aggravated by this fact, and for that reason, these organs have been considered in the revised classification of the World Health Organization (WHO) for this disease. Objective: To describe the affectation caused by dengue in organs such as the myocardium, the liver and the central nervous system (CNS) in children from Neiva, Colombia. Materials and methods: This study analyzed 930 children diagnosed with confirmed dengue and admitted to the Hernando Moncaleano Perdomo University Hospital of Neiva between January 2009 and December 2010. Diagnosis and clinical stratification were obtained based on the revised WHO classification. Dengue infection was confirmed by NS1 or specific IgM plasma detection. Daily clinical and paraclinical follow-up was performed during the full length of hospital stay. Results: Out of 930 children, 105 were classified as severe dengue (SD) and, of these, 19 had affected organs. The myocardium was the most compromised organ (14 cases), followed by the liver (4 cases) and the CNS (1 case). Conclusion: Clinical involvement of the myocardium, liver or CNS was observed in 18% of the cases of children with SD. A timely diagnosis and treatment of this pathology in children is necessary.
RESUMO
Macroalgae are potentially excellent sources of highly bioactive secondary metabolites that are useful for the development of new functional ingredients. This study was conducted to determine whether methanolic extracts from Caulerpa sertularioides and Ulva lactuca macroalgae might be possible alternatives for the prevention of shrimp vibriosis, which is caused by Vibrio parahaemolyticus and Vibrio alginolyticus. Macroalgae extracts prepared with methanol as the solvent were evaluated for antibacterial activity with the microplate method. The extracts' effects on the mortality of juvenile Litopenaeus vannamei were evaluated at doses of 150 and 300 mg L(-1). Two independent assays for V. parahaemolyticus and V. alginolyticus were performed. The methanolic extract of C. sertularioides exhibited activity against V. parahaemolyticus and V. alginolyticus, and it had minimal inhibitory concentrations of <1000 and < 1500 µg mL(-1), respectively. L. vannamei mortality in the presence of both The methanolic extract of C. sertularioides exhibited activity against V. parahaemolyticus and V. alginolyticus, and it had minimal inhibitory concentrations of <1000 and <1500 µg mL(-1), respectively. and V. alginolyticus bacteria significantly decreased after treatment with 300 mg L(-1) C. sertularioides methanolic extract.

BACKGROUND: The Lancet Commission on Global Surgery calls for universal access to safe, affordable, and timely surgical care. Two requisite components of timely access are (1) the ability to reach a surgical provider in a given timeframe, and (2) the ability to receive appropriately prompt care from that provider. We chose a threshold of 2 h in view of its relevance in time-to-death in post-partum haemorrhage. Here, we use geospatial mapping to enumerate the percentage of a nation's population living within 2 h of a surgeon and the surgeon-to-population ratio for each provider. METHODS: Geospatial mapping was used to identify the population living within a 2-h driving distance (access zone) of a health-care facility staffed by a surgeon. Surgeon locations were extracted from Ministries of Health, professional society databases, and published literature for countries which had available data. Data were reviewed by individuals knowledgeable of in-country distribution. Spatial distribution of providers was mapped with Google Maps engine. Access zones were constructed around every provider through estimation of driving times in Google Maps. The number of people living within zones was estimated with the Socioeconomic Data and Applications Center Population Estimation Service. Surgeon-to-population ratios were constructed for every individual access zone and averaged to report a single ratio. FINDINGS: Results (% country's population living within an access zone; average surgeon:population ratio within all access zones) are reported for nine countries with available data: Somaliland (16·9%; 1:118â306), Botswana (31·0%; 1:64â635), Ethiopia (39·6%; 1:229â696), Rwanda (41·3%; 1:158â484), Namibia (43·4%; 1:69â385), Zimbabwe (54%; 1:148â292), Mongolia (55·5%; 1:10â500), Sierra Leone (70·3%; 1:106â742), and Pakistan (84·4%, 1:139â299). Surgeon-to-population ratios vary substantially even within countries; in Sierra Leone, urban access zones have a ratio of 1:45â058 and rural access zones have a ratio of 1:467â929. INTERPRETATION: Surgical access is poor in many low-income and middle-income countries, even when using a narrow definition of surgical access consisting only of timeliness. Living outside of an access zone makes timely access to surgical care highly unlikely, and in view of low surgeon-to-population ratios and poor prehospital transport, even living within a 2-h access zone might not confer 2-h access. Investments in infrastructure and training must be prioritised to address widespread disparity in access to timely surgery. FUNDING: None.

An experimental investigation was performed to evaluate the productive and physiological responses of Litopenaeus vannamei that were infected with WSSV and fed diets enriched with Dunaliella sp., which had a high ß-carotene content induced by nitrogen reduction in the culture medium. A basal diet containing 35% crude protein and experimental diets T1 and T2, which included 1% and 2% microalgae meal, respectively, were evaluated. Positive (infected juveniles) and negative (non-infected) controls were also evaluated. Survival was significantly higher (80%) in the two treatment groups compared to the positive control group (56%). In the negative control group, survival was 100%. Some variation was recorded for hemolymph metabolites among treatments and at distinct times post-infection; although the tendencies were not clear, some metabolites (glucose and triglycerides) appeared to decrease on the last days of the trial, probably due to their use as energy for the shrimp to thrive despite the infection. The results of the study suggest a positive effect of the dietary inclusion of Dunaliella meal on shrimp survival and an unclear effect on hemolymph metabolites.

Shrimp postlarvae were reared into different microcosm systems without water exchange; a traditional system based on simple fertilization to improve microalgae concentration (control), an autotrophic system (AS) based on the promotion of biofloc and biofilm by the addition of fertilizer and artificial substrates and a heterotrophic system (HS) based on the promotion of heterotrophic bacteria by the addition of nitrogenous and carbonaceous sources and artificial substrates. Better growth performance and survival were registered in shrimp from the AS and HS compared to the control. Feed conversion ratios were below 0.7 for all treatments, but AS and HS were significantly lower than the control. Regarding digestive performance, no significant differences were observed for trypsin, amylase and lipase activities among AS and control shrimp; however, shrimp from HS showed a higher trypsin and amylase activities, suggesting a higher digestive activity caused by the presence of microbial bioflocs. The presence of biofilm and bioflocs composed by either autotrophic or heterotrophic organisms in combination with formulated feed improved the growth performance and survival of shrimp. Apparently, such combination fits the nutritional requirements of shrimp.

Previously, we have shown that wild type N-ras (wt N-ras) harbors an anti-malignant effect against mutated Ras and in tumors without Ras mutations. To investigate the molecular bases of this anti-malignant activity, we have studied the potency of this anti-malignant effect in a model system against SV40 large T antigen (SV40T). We show that wild-type N-ras (wt N-ras) counteracts the effects of SV40T in NIH3T3 cells as seen by a decrease in proliferation, anchorage independence and changes in migration. We also show that wt N-ras elicits the same anti-malignant effects in some human tumor cell lines (HT1080 and MDA-MB-231). Through mRNA and microRNA (miRNAs) expression profiling we have identified genes (decorin) and miRNAs (mir-29A, let-7b) modulated by wt N-ras potentially responsible for the anti-malignant effect. Wt N-ras appears to mediate its anti-malignant effect by downregulating some of the targets of the TGFß pathway and decorin, which are able to reverse the inhibition of migration induced by wt N-ras. Our experiments show that the molecules that mediate the anti-malignant effect by wt N-ras appear to be different from those modulated by transforming N-ras. The components of the pathways modulated by wt N-ras mediating its anti-malignant effects are potential targets for therapeutic intervention in cancer.

The increasing order of the mean concentrations of Cd, Cu, and Zn in the tissues of Mugil cephalus of seven coastal lagoons of Sinaloa State (NW Mexico) was liver > gills > muscle, while for Pb it was gills > muscle ≥ liver. There were no differences between the mean concentrations of Cd and Pb of the three tissues determined in the samples of the seven lagoons and, although there were some significant differences, there was no indication of a latitude-related trend in the distribution of Cu and Zn: the Cu content of the muscle tended to be higher in the northern than in the southern lagoons, although in the case of the gills the highest and lowest mean values indicated an opposite trend, with the highest and lowest values in one southern and one northern lagoon. In the case of the liver, there were no differences and no indication of a regional trend. There were no differences in the mean Zn contents of muscle and gills; in the case of the liver, one of the lagoons of the central part of the state had a significantly higher value than one of the southern lagoons and all the rest had similar values. In addition, there was no clear indication of season-related differences in any of the three tissues. According to our results, the metal contents of the muscle of this species are not of concern for human health, since the allowable ingestion would be in the order of 0.9 kg/day.

BACKGROUND: Dengue fever is one of the most significant re-emerging tropical diseases, despite our expanding knowledge of the disease, viral tropism is still not known to target heart tissues or muscle. METHODS: A prospective pediatric clinical cohort of 102 dengue hemorrhagic fever patients from Colombia, South America, was followed for 1 year. Clinical diagnosis of myocarditis was routinely performed. Electrocardiograph and echocardiograph analysis were performed to confirm those cases. Immunohistochemistry for detection of dengue virus and inflammatory markers was performed on autopsied heart tissue. In vitro studies of human striated skeletal fibers (myotubes) infected with dengue virus were used as a model for myocyte infection. Measurements of intracellular Ca2+ concentration as well as immunodetection of dengue virus and inflammation markers in infected myotubes were performed. RESULTS: Eleven children with dengue hemorrhagic fever presented with symptoms of myocarditis. Widespread viral infection of the heart, myocardial endothelium, and cardiomyocytes, accompanied by inflammation was observed in 1 fatal case. Immunofluorescence confocal microscopy showed that myotubes were infected by dengue virus and had increased expression of the inflammatory genes and protein IP-10. The infected myotubes also had increases in intracellular Ca2+ concentration. CONCLUSIONS: Vigorous infection of heart tissues in vivo and striated skeletal cells in vitro are demonstrated. Derangements of Ca2+ storage in the infected cells may directly contribute to the presentation of myocarditis in pediatric patients.
