Early Central Venous Catheter Replacement After Candida in Pediatric Intestinal Failure Patients.

Background: Deferred central venous catheter (CVC) replacement places children with intestinal failure (IF) at risk of complications. We hypothesized that early CVC replacement after uncomplicated candidemia is safe and beneficial. Methods: We performed a retrospective review of children with IF. Patients were divided into early (<7 days after their first negative culture), and late (≥7 days after their first negative culture) CVC replacement following uncomplicated candidemia. We calculated the median time to CVC removal, clearance of infection, CVC replacement or exchange, and duration of the initial hospitalization. The proportion of patients readmitted within 30 days was also calculated, taking note of the number of candida reinfections. Results: Early replacement occurred in 18 encounters and late replacement in 21 encounters. The median time in both groups to CVC removal was 3 days (P = 0.949), and clearance of infection was 4 days (P = 0.466). The median time to CVC replacement or exchange in the early group was 4 days, compared to 10 days in the late group (P < 0.001). The median duration of the hospitalization in the early group was 12 days compared to 21 days in the late group (P = 0.011). In total 39% of patients from the early group were readmitted within 30 days compared to 57% from the late group (P = 0.359). None of the patients were reinfected with candida within 30 days. Conclusion: Early CVC replacement after uncomplicated candidemia in children with IF decreases hospital stay without increased risk of readmission or reinfection.

Co-cultures of colon cancer cells and cancer-associated fibroblasts recapitulate the aggressive features of mesenchymal-like colon cancer.

Background: Poor prognosis in colon cancer is associated with a high content of cancer-associated fibroblasts (CAFs) and an immunosuppressive tumor microenvironment. The relationship between these two features is incompletely understood. Here, we aimed to generate a model system for studying the interaction between cancer cells and CAFs and their effect on immune-related cytokines and T cell proliferation. Methods: CAFs were isolated from colon cancer liver metastases and were immortalized to prolong lifespan and improve robustness and reproducibility. Established medium and matrix compositions that support the growth of patient-derived organoids were adapted to also support CAF growth. Changes in growth pattern and cellular re-organization were assessed by confocal microscopy, live cell imaging, and immunofluorescence. Single cell RNA sequencing was used to study CAF/organoid co-culture-induced phenotypic changes in both cell types. Conditioned media were used to quantify the production of immunosuppressive factors and to assess their effect on T cell proliferation. Results: We developed a co-culture system in which colon cancer organoids and CAFs spontaneously organize into superstructures with a high capacity to contract and stiffen the extracellular matrix (ECM). CAF-produced collagen IV provided a basement membrane supporting cancer cell organization into glandular structures, reminiscent of human cancer histology. Single cell RNA sequencing analysis showed that CAFs induced a partial epithelial-to-mesenchymal-transition in a subpopulation of cancer cells, similar to what is observed in the mesenchymal-like consensus molecular subtype 4 (CMS4) colon cancer. CAFs in co-culture were characterized by high expression of ECM components, ECM-remodeling enzymes, glycolysis, hypoxia, and genes involved in immunosuppression. An expression signature derived from CAFs in co-culture identified a subpopulation of glycolytic myofibroblasts specifically residing in CMS1 and CMS4 colon cancer. Medium conditioned by co-cultures contained high levels of the immunosuppressive factors TGFß1, VEGFA and lactate, and potently inhibited T cell proliferation. Conclusion: Co-cultures of organoids and immortalized CAFs recapitulate the histological, biophysical, and immunosuppressive features of aggressive mesenchymal-like human CRC. The model can be used to study the mechanisms of immunosuppression and to test therapeutic strategies targeting the cross-talk between CAFs and cancer cells. It can be further modified to represent distinct colon cancer subtypes and (organ-specific) microenvironments.

Association of total and pancreatic serum amylase enzymatic activity with insulin resistance and the glucose and insulin responses to oral starch test in Mexican children.

BACKGROUND/OBJECTIVES: Little is known about the effect of serum amylase enzymatic activity on glucose metabolism. We investigated the association of serum amylase enzymatic activity with fasting plasma glucose, insulin resistance (IR), and the plasma glucose and insulin response to an oral starch test (OST) in Mexican children. METHODS: Anthropometric data, glucose and insulin levels, and the serum enzymatic activity of total (AMYt), salivary (AMY1), and pancreatic (AMY2) amylase were analysed in 764 children (Nnormal weight  = 427/Nobesity  = 337). After categorization into low (LA) and high (HA) AMYt, an OST with commercial white bread was performed in 39 children (Nnormal weight  = 17/Nobesity  = 22). RESULTS: A positive association between serum enzymatic activity of AMY2 and IR was observed in children with obesity (p = 0.018). Children with normal weight had lower plasma glucose and insulin response to OST than children with obesity (Pglucose  = 4.1 × 10-12 ; Pinsulin  = 2.1 × 10-15 ). Compared with the LA group, children with HA showed lower plasma glucose and insulin response to OST (Pglucose ≤ 0.040; Pinsulin ≤ 0.015). CONCLUSION: Our results suggest that AMY2 is positively associated with IR. A high level of AMYt is related to lower glucose and insulin responses to OST in Mexican children, regardless of their weight status.

Validation and uncertainty estimation of analytical method for quantification of phytochelatins in aquatic plants by UPLC-MS.

Phytochelatins (PCs) are peptides that play an important role in homeostasis and detoxification of heavy metal in plants. Furthermore, they have been proposed as earlier potential biomarkers of aquatic pollution by heavy metals. Nowadays, several researchers have reported on current methods for quantification of glutathione (GSH) and the PCs (phytochelatin 2, phytochelatin 3, phytochelatin 4) quantification in plants. However, no method has reported the uncertainty of the measurement, which helps to improve the accuracy and quality assurance in the PC quantification. In this work, a new methodology using ultra-high-performance liquid chromatography coupled to mass spectrometry (UPLC-MS) to measure with high precision and accuracy the PCs in aquatic plants, was validated. Selectivity, linearity, limit of detection, limit of quantification, precision, trueness and uncertainty estimation were examined as parts of the method validation. The described method shows excellent linearity in different ranges for all analytes with coefficients of determination higher than 0.99. The relative standard deviation for intra-day precision was <3% and for inter-day <10%. All LOD and LOQ analytes ranged from 0.02 to 0.08 µg ml-1, and from 0.03 to 0.09 µg ml-1, respectively. The recoveries varied from 61% to 89%. In order to obtain an interval of results with the highest confidence levels, the uncertainty associated with the measurements was evaluated. The calibration curve (>50%) and recovery (19-44%) were the most important contributors to the total uncertainty. The proposed method was applied to quantify GSH and PCs in the aquatic plants Lemna gibba L., Myriophyllum heterophyllum Michx., Arenaria paludicola and Hydrocotyle ranunculoides L. fil., showing statistical differences in the mass fraction of the analytes.

Infection Risk Prediction Model for COVID-19 Based on an Analysis of the Settlement of Particles Generated during Dental Procedures in Dental Clinics.

BACKGROUND: The health emergency declaration owing to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has drawn attention toward nosocomial transmission. The transmission of the disease varies depending on the environmental conditions. Saliva is a recognized SARS-CoV-2 reservoir in infected individuals. Therefore, exposure to fluids during dental procedures leads to a high risk of contagion. OBJECTIVE: This study aimed to develop an infection risk prediction model for COVID-19 based on an analysis of the settlement of the aerosolized particles generated during dental procedures. MATERIALS AND METHODS: The settlement of aerosolized particles during dental aerosol-generating procedures (AGPs) performed on phantoms was evaluated using colored saliva. The gravity-deposited particles were registered using a filter paper within the perimeter of the phantom head, and the settled particles were recorded in standardized photographs. Digital images were processed to analyze the stained area. A logistic regression model was built with the variables ventilation, distance from the mouth, instrument used, area of the mouth treated, and location within the perimeter area. RESULTS: The largest percentage of the areas stained by settled particles ranged from 1 to 5 µm. The maximum settlement range from the mouth of the phantom head was 320 cm, with a high-risk cutoff distance of 78 cm. Ventilation, distance, instrument used, area of the mouth being treated, and location within the perimeter showed association with the amount of settled particles. These variables were used for constructing a scale to determine the risk of exposure to settled particles in dentistry within an infection risk prediction model. CONCLUSION: The greatest risk of particle settlement occurs at a distance up to 78 cm from the phantom mouth, with inadequate ventilation, and when working with a high-speed handpiece. The majority of the settled particles generated during the AGPs presented stained areas ranging from 1 to 5 µm. This model was useful for predicting the risk of exposure to COVID-19 in dental practice.

Acutely altered mental status as the main clinical presentation of multiple strokes in critically ill patients with COVID-19.

BACKGROUND AND AIMS: Cerebral infarction in COVID-19 patients might be associated with a hypercoagulable state related to a systemic inflammatory response. Its diagnosis might be challenging. We present two critically ill patients with COVID-19 who presented acutely altered mental status as the main manifestation of multiple strokes. METHODS: Clinical presentation and diagnostic work-up of the patients. RESULTS: Two patients in their sixties were hospitalized with a bilateral pneumonia COVID-19. They developed respiratory failure and were admitted to ICU for mechanical ventilation and intense medical treatment. They were started on low-molecular-weight heparin since admission. Their laboratory results showed lymphopenia and increased levels of C-reactive protein and D-dimer. Case 1 developed hypofibrinogenemia and presented several cutaneous lesions with biopsy features of thrombotic vasculopathy. Case 2 was performed a CT pulmonary angiogram at ICU showing a bilateral pulmonary embolism. When waking up, both patients were conscious but with a remarkable global altered mental status without focal neurological deficits. A brain MRI revealed multiple acute bilateral ischemic lesions with areas of hemorrhagic transformation in both patients (case 1: affecting the left frontal and temporal lobes and both occipital lobes; case 2: affecting both frontal and left occipital lobes). Cardioembolic source and acquired antiphospholipid syndrome were ruled out. COVID-19-associated coagulopathy was suspected as the possible main etiology of the strokes. CONCLUSION: Acutely altered mental status might be the main manifestation of multiple brain infarctions in critically ill COVID-19 patients. It should be specially considered in those with suspected COVID-19-associated coagulopathy. Full-dose anticoagulation and clinical-radiological monitoring might reduce their neurological consequences.

Sex is a strong prognostic factor in stage IV non-small-cell lung cancer patients and should be considered in survival rate estimation.

BACKGROUND: Biological differences between the sexes have a major impact on disease and treatment outcome. In this paper, we evaluate the prognostic value of sex in stage IV non-small-cell lung cancer (NSCLC) in the context of routine clinical data, and compare this information with other external datasets. METHODS: Clinical data from stage IV NSCLC patients from Hospital Puerta de Hierro (HPH) were retrieved from electronic health records using big data analytics (N = 397). In addition, data from the Spanish Lung Cancer Group (GECP) Tumor Registry (N = 1382) and from a published study available from the cBioPortal (MSK) (N = 601) were analyzed. Survival curves were estimated using the Kaplan-Meier method. A Cox proportional hazards regression model was used to assess the prognostic value of sex. A meta-analysis to compare the outcome for males and females in terms of overall survival (OS) and progression free survival (PFS) was performed. RESULTS: The median OS time was 12 months for males and 19 months for females (overall HR = 0.77; 95% CI: 0.68-0.87; P < 0.001). Similarly, females with stage IV NSCLC harboring an EGFR-sensitizing mutation lived significantly longer than males (median OS: males, 19 months; females, 32 months) with a lower risk of death compared with males (overall HR = 0.75; 95% CI: 0.67-0.84). In addition, female patients benefited more from EGFR inhibitors in terms of PFS and OS (overall HR = 0.45; 95% CI: 0.32-0.64, and HR = 0.62; 95% CI: 0.48-0.80, respectively). Median PFS was 21 months in females and 12 months in males (P < 0.001). CONCLUSIONS: Using routine clinical data we confirmed the previous finding that among stage IV NSCLC patients, females had a significantly better prognosis than males. The effect size of the sex was notable, highlighting the fact that survival rates are usually estimated and patients are generally managed without considering the sexes separately, which may lead to suboptimal results.

Terapia Electroconvulsiva y Estimulación Magnética Transcraneal Repetitiva en pacientes con esquizofrenia: una revisión sistemática / Electroconvulsive Therapy and Repetitive Transcranial Magnetic Stimulation in patients with schizophrenia: a systematic review

Cuando la esquizofrenia no responde satisfactoriamente a tratamiento farmacológico, alcanzar una terapia efectiva para el paciente es una tarea bastante frustrante para el médico psiquiatra. Es en este contexto que la terapia electroconvulsiva y la estimulación magnética transcraneal repetitiva han tomado fuerza en la investigación clínica, a pesar de los grandes cuestionamientos sobre su efectividad y mala reputación. Se realizó una revisión sistemática de la literatura en las principales bases de datos disponibles. Concluyendo que ambas terapias demuestran ser herramientas útiles en el tratamiento de la esquizofrenia resistente a tratamiento farmacológico, así como también complementarias a los antipsicóticos

When schizophrenia does not respond satisfactorily to pharmacological treatment, achieving effective therapy for the patient is quite a frustrating task for the psychiatrist. It is in this context that electroconvulsive therapy and repetitive transcranial magnetic stimulation have gained strength in clinical research, despite huge questions about its success and bad reputation. A systematic review of the literature was conducted in the main available databases. Concluding that both specific therapies will be useful tools in the treatment of schizophrenia resistant to pharmacological treatment, as well as complementary to antipsychotics.

Aqueous extract of Sedum oxypetalum induces mineralization and osteogenic differentiation by human Periodontal Ligament-Derived cells.

ETHNOPHARMACOLOGICAL RELEVANCE: The medicinal plant Sedum oxypetalum Kunth (Crassulaceae), locally known as Jiote or in general Siempreviva (always alive) has been traditionally used by people of the Mexican community of Tenango del Valle as a home remedy to treat periodontal diseases, inducing teeth strengthening. Consequently, the aim of this work was to investigate its capacity directed to mineralized tissues regeneration. MATERIALS AND METHODS: The aerial parts of the plant were processed and its aqueous extract (AE) was chemically characterized. The AE and its components sedoheptulose and syngenite were tested for either osteogenic differentiation or mineral-nucleation induction respectively. RESULTS: The AE and one of its components (sedoheptulose) were shown to promote the proliferation and/or osteogenic differentiation by Human Periodontal Ligament-Derived Cells (hPDLs), while inducing the mineralization process. The AE also promoted the nucleation of octacalcium phosphate and its component syngenite, the hydroxyapatite crystals formation in vitro. CONCLUSION: The findings reported herein support the traditional use of S. oxypetalum due to its potential capacity to promote the regeneration of mineralized tissues.

Conclusión: la baja escolaridad, una edad avanzada y sufrir HTA son en su orden los factores más importantes para el desarrollo de la demencia. Los adultos entre 70 y 79 años con bachillerato incompleto, tienen mayor riesgo de DCL.

Introduction: The relationship between some metabolic and cardiovascular risk factors (CVRF) and cognitive impairment (CI) defined as mild cognitive impairment (MCI) and dementia, is controversial. Objective: Describe the cardiovascular and metabolic risk factors that are associated with cognitive impairment in adults from Bogotá. Materials and methods: A cross-sectional study, where the state of cognitive functions (normal, MCI or dementia) was evaluated in two phases, in adults older than 50 years, autonomous, non-institutionalized, using neuropsychological tests and neuropsychiatric protocol. Its cardiovascular and metabolic risk by self-reported history and standardized anthropometric measurements were documented. Results: Of 1045 adults surveyed, the mean age of the group was 68 years(SD 8.6), and the mean education level was 8 years(SD 6.0), 76% were women, 56% had hypertension(HT), 40% dyslipidemia, 37% were smokers, 36% were overweight, 28% presented hypothyroidism, 25% were obese, 17% drank alcohol and 16% were diabetic. MCI was associated with incomplete high school education OR:3.01(95% CI 1.80-5.05) and aged between 70 and 79 years OR:2.06(95%CI 1.32-3.23). Dementia was associated with lower scholarity, incomplete-primary OR:11.20(95%CI 4.99-25.12), complete-primary OR 7.91(95% CI.3.44-18.16), incomplete-high school OR: 2.87(95% CI 1.17-7.01), age over 80 years OR:7.68(95%CI 3.49-16.90); and suffer hypertension OR:1.45(95%CI 1.03- 2.05) Conclusion: Low education, older age and hypertension are in order, the most important risk factors for the development of dementia in our population. Adults between 70 and 79 with incomplete high school have higher risk of MCI.

Synthesis of Fischer type-carbene complexes containing a coordinated thioimidate structural motif.

This paper describes a tandem strategy to synthesize a series of new Fischer carbene complexes [(CO)(4)M=C[N-(CH(2))(4)-]CH=C(NRR')(SR'); M = Cr, W; R = Ar, R' = Me, -(CH(2))(2)-] with a thioimide or thiazoline fragment, in which the sulfur or nitrogen atom is coordinated to a metal center, depending on the nature of alkylating groups included as R'. We have trapped by protonation the proposed intermediate as the thioamide 12 [(CO)(5)W=[N-(CH(2))(4)-]CH(2)C(S)NHPh], which reveals the pathway of this reaction.

Prevalencia y comportamiento de la demencia en ancianos de un consejo popular del municipio Jaruco / Prevalence and behavior of Dementia in Elderly People of a Popular Council in Jaruco municipality

Se realizó un estudio analítico prospectivo en el periodo comprendido entre enero y diciembre del 2006 en los siete consultorios del médico de la familia del Consejo Popular San Antonio de Río Blanco, ubicado en el área de salud del Policlínico Docente Noelio Capote del municipio Jaruco, para determinar la existencia de enfermedad demencial y su comportamiento en los 912 adultos mayores examinados.

Torsión del apéndice cecal asociada a invaginación intestinal / Torsion of the vermiform appendix associated with intussusception

La torsión del apéndice vermiforme es muy rara; en la literatura sólo han sido referidos 25 casos. El aquí informado es el primero asociado a invaginación intestinal. Se trató de una niña de dos meses de edad quien súbitamente dio muestras de dolor. En la exploración quirúrgica se encontró invaginación ileocecal apretada, que fue corregida. Cuatro días después fue necesario reoperar, encontrando torsión y perforación del apéndice cecal; se practicó apendicectomía. Por datos de obstrucción y peritonitis se requirió nueva exploración quirúrgica en la que se encontró dehiscencia del muñón y perforación cecal. Una vez corregidas estas complicaciones, la paciente evolucionó satisfactoriamente y fue dada de alta en buenas condiciones.

BACKGROUND: Vermiform appendix torsion is a rare condition, with only 25 cases recorded in the international literature. Our patient is the first case associated with intussusception. CASE REPORT: A 2-month-old female infant suddenly developed severe abdominal pain due to ileoceal intussusception. During surgical exploration, a tight intussusception was reduced. Three days later, a new laparotomy was required and we found torsion and perforation of the vermiform appendix. The patient underwent appendectomy, but there was dehiscence of the appendiceal stump and cecal perforation requiring a new surgical exploration. The patient had an uneventful recovery.

A newborn male patient with trisomy-21 presented with bilious hemesis. The patient was icteric with slight hepatomegaly. Simple abdominal X-ray and upper gastrointestinal series with barium showed a dilated duodenal loop and inflammatory changes involving the duodenal mucosa. This image known as "double bubble" is characteristic of congenital duodenal obstruction. Simultaneously the gallbladder and choledochus were visualized. The former X-ray finding is very unusual. An uneventful Kimura procedure was performed.
