Brain transcriptome analysis of a CLN2 mouse model as a function of disease progression.

BACKGROUND: Neuronal ceroid lipofuscinoses, (NCLs or Batten disease) are a group of inherited, early onset, fatal neurodegenerative diseases associated with mutations in 13 genes. All forms of the disease are characterized by lysosomal accumulation of fluorescent storage material, as well as profound neurodegeneration, but the relationship of the various genes' function to a single biological process is not obvious. In this study, we used a well-characterized mouse model of classical late infantile NCL (cLINCL) in which the tripeptidyl peptidase 1 (Tpp1) gene is disrupted by gene targeting, resulting in loss of detectable TPP1 activity and leading to progressive neurological phenotypes including ataxia, increased motor deficiency, and early death. METHODS: In order to identify genes and pathways that may contribute to progression of the neurodegenerative process, we analyzed forebrain/midbrain and cerebellar transcriptional differences at 1, 2, 3 and 4 months of age in control and TPP1-deficient mice by global RNA-sequencing. RESULTS: Progressive neurodegenerative inflammatory responses involving microglia, astrocytes and endothelial cells were observed, accompanied by activation of leukocyte extravasation signals and upregulation of nitric oxide production and reactive oxygen species. Several astrocytic (i.e., Gfap, C4b, Osmr, Serpina3n) and microglial (i.e., Ctss, Itgb2, Itgax, Lyz2) genes were identified as strong markers for assessing disease progression as they showed increased levels of expression in vivo over time. Furthermore, transient increased expression of choroid plexus genes was observed at 2 months in the lateral and fourth ventricle, highlighting an early role for the choroid plexus and cerebrospinal fluid in the disease pathology. Based on these gene expression changes, we concluded that neuroinflammation starts, for the most part, after 2 months in the Tpp1-/- brain and that activation of microglia and astrocytes occur more rapidly in cerebellum than in the rest of the brain; confirming increased severity of inflammation in this region. CONCLUSIONS: These findings have led to a better understanding of cLINCL pathological onset and progression, which may aid in development of future therapeutic treatments for this disease.

Supreme™ laryngeal mask airway insertion requires a lower concentration of sevoflurane than ProSeal™ laryngeal mask airway insertion during target-controlled remifentanil infusion: a prospective randomised controlled study.

BACKGROUND: ProSeal (PLMA) and Supreme (SLMA) laryngeal mask airways are effective ventilator devices with distinctive designs that may require different anaesthetics for insertion. Sevoflurane induction provides acceptable conditions for laryngeal mask insertion, and remifentanil significantly decreases the minimum alveolar concentration of sevoflurane required for that insertion. The study aimed to evaluate the optimal end-tidal (ET) sevoflurane concentration for successful insertion of PLMA versus SLMA in patients receiving a remifentanil infusion without a neuromuscular blocking agent. METHODS: Altogether, 45 patients ASA (American Society Anaesthesiologists) physical status I-II, aged 18-60 years were scheduled for elective ambulatory surgery. Exclusion criteria were a difficult airway, recent respiratory infection, reactive airway, obstructive sleep apnoea syndrome, gastric aspiration's risk factors, pregnancy, and lactation. Patients were randomly allocated to receive the SLMA or the PLMA. Sevoflurane induction with co-administration of remifentanil was performed at an effect-site concentration of 4 ng mL- 1. ET50 was calculated with a modified Dixon's up-and-down method (starting at 2.5% in steps of 0.5%). Predetermined sevoflurane concentration was kept constant during the 10 min before LMA insertion. Patient's response to LMA insertion was classified as "movement" or "no movement". Sevoflurane ET50 was determined as the midpoint concentration of all the independent pairs that manifested crossover from "movement" to "no movement". RESULTS: The ET50 sevoflurane concentration co-administered with remifentanil required for PLMA insertion was 1.20 ± 0.41% (95% confidence interval 0.76 to 1.63%). For SLMA insertion, it was 0.55 ± 0.38% (95% confidence interval 0.14 to 0.95%) (p = 0.019). CONCLUSIONS: The end-tidal sevoflurane concentration with co-administered remifentanil required to allow insertion of the SLMA was 54% lower than that needed for inserting the PLMA. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03003377. Retrospectively registered. Date of registration: December 28, 2016.

Unexpected relevant role of gene mosaicism in patients with primary immunodeficiency diseases.

BACKGROUND: Postzygotic de novo mutations lead to the phenomenon of gene mosaicism. The 3 main types are called somatic, gonadal, and gonosomal mosaicism, which differ in terms of the body distribution of postzygotic mutations. Mosaicism has been reported occasionally in patients with primary immunodeficiency diseases (PIDs) since the early 1990s, but its real involvement has not been systematically addressed. OBJECTIVE: We sought to investigate the incidence of gene mosaicism in patients with PIDs. METHODS: The amplicon-based deep sequencing method was used in the 3 parts of the study that establish (1) the allele frequency of germline variants (n = 100), (2) the incidence of parental gonosomal mosaicism in families with PIDs with de novo mutations (n = 92), and (3) the incidence of mosaicism in families with PIDs with moderate-to-high suspicion of gene mosaicism (n = 36). Additional investigations evaluated body distribution of postzygotic mutations, their stability over time, and their characteristics. RESULTS: The range of allele frequency (44.1% to 55.6%) was established for germline variants. Those with minor allele frequencies of less than 44.1% were assumed to be postzygotic. Mosaicism was detected in 30 (23.4%) of 128 families with PIDs, with a variable minor allele frequency (0.8% to 40.5%). Parental gonosomal mosaicism was detected in 6 (6.5%) of 92 families with de novo mutations, and a high incidence of mosaicism (63.9%) was detected among families with moderate-to-high suspicion of gene mosaicism. In most analyzed cases mosaicism was found to be both uniformly distributed and stable over time. CONCLUSION: This study represents the largest performed to date to investigate mosaicism in patients with PIDs, revealing that it affects approximately 25% of enrolled families. Our results might have serious consequences regarding treatment and genetic counseling and reinforce the use of next-generation sequencing-based methods in the routine analyses of PIDs.

Qualitative Study of Certified Peer Specialists' Experiences Delivering Peer Support Services During the COVID-19 Pandemic.

OBJECTIVE: The purpose of this qualitative study was to examine the experiences of certified peer specialists (CPSs) in delivering telehealth services during the COVID-19 pandemic. METHODS: Fourteen semistructured interviews with CPSs were conducted from August to November 2020. Data were analyzed by using thematic analysis. RESULTS: Helpful support from employers during the transition to telehealth included clear communication and access to training on telehealth technologies. Main barriers and facilitators were related to interpersonal relationships and logistical factors. CPSs reported that telehealth allowed them to continue to support the peers they serve but that the quality of interactions was not as good as with in-person services. Logistical challenges included inadequate equipment and Internet access. CONCLUSIONS: To support CPSs in delivering telehealth, employers can engage them in open and transparent communication about guidelines for service delivery, provide training and equipment, and allow them the flexibility to tailor service delivery modalities to the peers they serve.

Rasch development and validation of a new faces scale for measuring pain, and its comparison with a gold standard: the Balparda-Herrera Pain Scale.

Aim: Faces pain scales are widely used to measure pain. So far, no faces pain scale has ever been constructed by Rasch modeling. Hence the authors aimed to construct a new scale by this method. Methods: Rasch modeling was used to provide an initial calibration and development of the 'Balparda-Herrera Pain Scale' (BHPS) and this scale was compared with the existing Faces Pain Scale - Revised. The scale was later refined. Results: Both the existing scale and the initial version of the BHPS required category collapsing. Statistical tests demonstrated an excellent concordance between both scales. The final version of the BHPS was found to behave excellently and to be capable of adequately measuring pain. Conclusion: The BHPS provides an excellent instrument for measuring pain in the adult population.

Lay abstract Pain is an unpleasant experience for patients, and it is useful for physicians to try to measure how much pain the patient is experiencing. Some scales used by physicians include faces with different expressions to represent various amounts of pain. Rasch modeling is a mathematical approach to develop better scales. In this study, the researchers performed two surveys in order to develop and improve a new scale for measuring pain: the Balparda­Herrera Pain Scale. They used mathematical and statistical approaches to optimize the scale and to compare with another well-known scale. The authors found that the new scale is very useful for measuring pain.

Prolonged stability of the plantibody HB-01 directed against the hepatitis B surface antigen in cryo-preserved tobacco leaves.

Since 1983, several recombinant antibodies have been expressed in important agronomic plant species. However, to date no evaluation has been published about prolonged antibody stability within plant tissues under cryo-preservation conditions. This current report presents an approach to the KDEL-plantibody HB-01 (PHB-01) stability in frozen tobacco leaves by presenting scientific evidence about the stability of a plantibody to a prolonged low temperature exposure in this biological source. Results clearly show that the PHB-01 amount is maintained during the storage of tobacco leaves at -20 degrees C for 90 days. The PHB-01 recovery was not affected by any irreversible physical and/or chemical change produced in tobacco leaves after this cryo-preservation time. The amount of total soluble proteins in the clarified extract decreased in proportion with the storage time and the PHB-01 molecules isolated from frozen leaf extracts were highly pure, >95%, according to an SDS-PAGE assessment under reducing conditions. Low temperature exposure of tobacco leaves did not reveal visible changes in frozen leaves, which is essential for the further extractability of proteins. The PHB-01 is stable in tobacco leaves at -20 degrees C during 90 days, which offers the possibility to overcome problems associated with detrimental climate conditions and optimize purification capabilities.

Non-lupus full house nephropathy in pediatrics: Case reports / Nefropatía full house no lúpica en pediatría: reporte de dos casos.

Full house nephropathy is defined as the simultaneous detection of IgA, IgG, IgM, C3, and C1q deposits by immunofluorescence, usually indicating lupus nephritis. There are patients with this immunofluorescence pattern, but with negative autoantibody serology, which means they cannot be diagnosed with systemic lupus erythematosus. Patients presenting with full house nephropathy but no other criteria for lupus are diagnosed as having nonlupus full house nephropathy. Here, we describe two cases: A male patient who debuted with rapidly progressive glomerulonephritis and a female patient with nephrotic syndrome. Both had negative autoantibody serology, findings in the renal biopsy of class IV lupus nephritis and afull house immunofluorescence pattern. Histological findings in non-lupus full house nephropathy are similar to those in lupus nephritis and, probably, similar physiopathological bases. However, prospective studies are needed to determine risk factors and the renal prognosis and to make suggestions for specific treatments.

La nefropatía full house se refiere a la detección simultánea de depósitos de IgA, IgG, IgM, C3 y C1q en la inmunofluorescencia, lo que generalmente indica la presencia de nefritis lúpica. Hay pacientes con este patrón de inmunofluorescencia, pero con serología negativa para autoanticuerpos, por lo que no se les puede diagnosticar un lupus eritematoso sistémico. Este tipo de nefropatía, en la que no se presentan otros criterios para lupus, se denomina nefropatía full house no lúpica. En esta presentación, se describen dos casos: un paciente que ingresó con una glomerulonefritis rápidamente progresiva y una paciente con síndrome nefrótico, ambos con serología negativa para autoanticuerpos, hallazgos en la biopsia renal indicativos de nefritis lúpica de clase IV y un patrón full house en la inmunofluorescencia. La nefropatía full house no lúpica tiene rasgos histológicos similares a los de la nefritis lúpica y, probablemente, sus bases fisiopatológicas son parecidas. Sin embargo, se necesitan estudios prospectivos para conocer los factores de riesgo y el pronóstico renal, y poder hacer sugerencias sobre tratamientos específicos.

Juvenile polyautoimmunity in a rheumatology setting.

Overt polyautoimmunity (PolyA) corresponds to the presence of more than one well-defined autoimmune disease (AD) manifested clinically in a single patient. The current study aimed to describe the main characteristics of juvenile PolyA in a pediatric rheumatology setting and analyze the chronological aspects, index cases, familial autoimmunity, and clustering pattern. This was a cross-sectional and multicenter study in which 313 children with overt PolyA were included. Patients were systematically interviewed and their medical records reviewed using a questionnaire that sought information about demographic, clinical, immunological, and familial characteristics. A hierarchical cluster analysis was done to determine similarities between autoimmune diseases based on PolyA. PolyA occurred simultaneously in 138 (44%) patients. Multiple autoimmune syndrome was observed in 62 (19.8%) patients. There were 25 index diseases of which, systemic lupus erythematosus (SLE, n = 134, 42.8%), juvenile idiopathic arthritis (JIA, n = 40, 12.7%), Hashimoto's thyroiditis (HT, n = 24, 7.66%), immune thrombocytopenic purpura (ITP n = 20, 6.39%), antiphospholipid syndrome (APS, n = 15, 4.79%), and vitiligo (VIT, n = 15, 4.79%) were the most frequent and represented 79.23% of the total number of patients. Familial autoimmunity influenced PolyA. A high aggregation of autoimmunity was observed (λr = 3.5). Three main clusters were identified, of which SLE and APS were the most similar pair of diseases (based on the Jaccard index) followed by HT and JIA, which were related to ITP and Sjögren's syndrome. The third cluster was composed of localized scleroderma and VIT. Our findings may assist physicians to make an early diagnosis of this frequent condition. Pediatric patients with ADs should be systematically assessed for PolyA.

Autoantibodies and Gastrointestinal Symptoms in Colombian Children with Juvenile Idiopathic Arthritis.

BACKGROUND: Juvenile Idiopathic Arthritis (JIA) is the most common inflammatory joint disease in children. JIA and autoimmune inflammatory Gastrointestinal (GI) diseases share common etiologic mechanisms, including genetic predisposition and environmental influences. OBJECTIVE: To Investigate association between gastrointestinal, rheumatologic clinical variables and the presence of autoantibodies in patients with JIA in treatment. METHODOLOGY: In a cross-sectional study of patients with JIA according to diagnostic criteria and the ILAR classification. GI symptoms and autoantibody expression were evaluated with respect to their association with JIA clinical variables. Anti-Saccharomyces Cerevisiae IgG/IgA (ASCA), 6 antigen associated with anti polymorphonuclear neutrophil (ANCA), anti Transglutaminase (tTG) IgG/IgA, anti deaminated gliadin peptide (DGP) IgG/IgA autoantibodies, ANAS and IgA were measured in all patients. The association between clinical variables and auto-antibodies were evaluated using the Fisher test with significant value of p <0.05. The study was approved by the ethics committee of the all institutions. RESULTS: Samples were collected from ninety-seven patients, 63% of whom were female. The average age was 14 years. The JIA subtype associated with the most common GI symptoms was enthesitis- related arthritis. Of these patients, 44.3% and 14% reported abdominal pain and diarrhea, respectively. Anti-DPG and anti-tTG antibodies were found in 9.28% and 7.22%, respectively and 11.34% were positive for p-ANCA, and 2% were positive for ASCA. CONCLUSION: GI symptoms and autoantibodies associated with inflammation of the GI mucosa were detected in JIA patients but were not associated with autoantibodies or clinical variables. However, it is the monitoring of these patients diagnosis is important.

Is steroid resistance related to multidrug resistance-I (MDR-I) in rheumatoid arthritis?

Both healthy ageing and rheumatoid arthritis (RA) are frequently associated with acquired steroid resistance. Here, we investigated the potential involvement of steroid resistance with multidrug resistance (MDR) and explored the impact of pathological ageing on lymphocyte sensitivity to glucocorticoids. Seventy-four RA patients and 26 healthy controls took part in this study. Peripheral blood mononuclear cells were isolated and T-cell sensitivity to glucocorticoids was measured in vitro. The functional activity of P-glycoprotein was analyzed by flow cytometry and ABCB1/MDR-1 gene polymorphisms were assessed in peripheral lymphocytes. Patients and controls had similar sensitivities to glucocorticoids. Only controls presented age-related immunological changes, including reduced T-cell proliferation and relative resistance to corticosterone. Patients had a higher percentage (72%) of lymphocytes actively extruding rhodamine 123 (Rh123(dim)) than controls (60%) in spite of similar P-glycoprotein activity. A higher percentage of Rh123(dim)+ lymphocytes was observed in patients who were more resistant to dexamethasone in vitro. The distribution of ABCB1 genotypes in RA patients did not differ significantly from that in controls and were not associated to steroid sensitiveness or disease activity. These data suggest that peripheral lymphocytes of arthritic patients are fully responsive to GCs in vitro in spite of displaying higher MDR activity.

La información se organizó en: cuadro clínico, cuidados de enfermería y dificultades en la atención gineco-obstétrica. Discusión: El profesional de enfermería debe identificar barreras en la atención evaluando la capacidad resolutiva de las instituciones y analizando los casos de muerte materna. Se recomienda el uso de misoprostol con oxitocina o únicamente de carbetocina y la combinación de ergometrina con oxitocina según el volumen de sangrado. Conclusión: Es pertinente realizar un examen físico para reconocer signos de inestabilidad hemodinámica, y de shock hipovolémico. Además, los diagnósticos e intervenciones de enfermería se enfocan en brindar cuidados de calidad, para evitar complicaciones como la muerte.

Introduction: In Colombia, postpartum hemorrhage is the second leading cause of death in pregnant women at a rate of 6.9 deaths per 1,000 live births. After childbirth, 8.2% of Latin American women are expected to have postpartum hemorrhage. Objective: To describe nursing care delivered to women with postpartum hemorrhage to reduce the risk of hypovolemic shock by means of an integrative literature review. Materials and Methods: Following the approach suggested by Sasso, de Campos and Galvão, an integrative literature review was conducted on ClinicalKey, LILACS, CINAHL, Epistemonikos, Cochrane Library, PubMed and ScieELO Google Scholar databases. Articles published in the last five years in Spanish, English and Portuguese were selected and classified by their level of evidence and degree of recommendation. This is a low-risk research due to its documentary nature. Results: 41 articles were finally selected and classified into clinical picture, nursing care and challenges in OBGYN care. Discussion: Nursing professionals should identify barriers to care by evaluating institutional problem-solving capacity and analyzing maternal death cases. Using misoprostol and oxytocin or only carbetocin and ergometrine-oxytocin is suggested based on the quantity of blood loss. Conclusions: Performing a physical examination is important to recognize signs of hemodynamic instability and hypovolemic shock. Nursing diagnoses and interventions focus on providing quality patient care to prevent certain complications such as death.

Características de la maternidad adolescente en un hospital del segundo nivel del contexto ecuatoriano / Characteristics of adolescent motherhood in a second-level hospital in the Ecuadorian context

La vulnerabilidad de los adolescentes se acentúa durante la maternidad debido a las posibles complicaciones biopsicosociales para el binomio madre-hijo. Así, se desarrolló un estudio observacional, descriptivo y de corte transversal, con un enfoque cuantitativo, cuya población estuvo integrada por 62 madres adolescentes, en puerperio inmediato, ingresadas en el Servicio de Ginecología y Obstetricia en el contexto de un hospital del segundo nivel de atención de la ciudad de Riobamba, durante el primer semestre del año 2019. Predominaron las edades perte-necientes a la etapa de la adolescencia tardía (77,4%), las autoidentificadas como mestizas, las que profesaban religión católica, el estado civil de unión libre o solteras y las de profesión de ama de casa. También, aquellas que no planificaron su embarazo (71%) y las que consideraron como deseado a su hijo. La mayoría de los adolescentes declararon no usar métodos anticoncep-tivos, no tener antecedentes patológicos familiares (67,74%) ni personales de interés (45,16%); aunque, entre estos últimos destacaron las infecciones de vías urinarias, que también constitu-yeron la principal enfermedad durante el embarazo. Preponderaron las embarazadas que se hicieron más de 5controles prenatales, las que cumplieron con las indicaciones y acudieron a las consultas de seguimiento, así como, la ausencia de complicaciones en los recién nacidos. El autoconcepto de las adolescentes puérperas participantes no se afectó gravemente en ninguna de estas, existiendo un predominio de afección entre moderada y leve, además de la categoría ninguna. En relación con el desempeño, predominaron aquellas en las que no se afectó.

The vulnerability of adolescents is accentuated during motherhood due to possible biopsychoso-cial complications for the mother-child binomial. An observational, descriptive, and cross-sec-tional study was developed with a quantitative approach. The population was made up of 62 adolescent mothers, in the immediate puerperium, admitted to the Gynecology and Obstetrics Service in the context of a second-level hospital of attention in the city of Riobamba, during the first semester of the year 2019. The predominated results were: the ages belonging to the late adolescence stage (77.4%), those self-identified as mestizo, those who professed a Catholic religion, the civil status of free union or single and those of the profession of housewife. Besides, those ones who did not plan their pregnancy (71%) and those ones who considered their child as desired. Most of the adolescents declared that they did not use contraceptive methods, did not have a family pathological history (67.74%) or personal history of interest (45.16%); although, among the latter, urinary tract infections stood out, which were also the main disease during pregnancy. The preponderance of pregnant women who underwent more than 5 prenatal check-ups, those who complied with the indications and attended follow-up consultations, as well as the absence of complications in the newborns. The self-concept of the participating puer-peral adolescents was not seriously affected in any of them, with a predominance of affection between moderate and mild, including the category none. In relation to performance, those ones that were not affected predominated.

La reconstrucción mamaria ha evolucionado no solo en las cuestiones estéticas, sino también, a favor de lograr menor morbilidad en las pacientes afectadas. Objetivo: describir los resultados obtenidos con la aplicación de técnicas oncoplásticas en pacientes con cáncer de mama. Método: se realizó un estudio descriptivo de una serie de 41 pacientes en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus desde marzo de 2018 hasta octubre de 2020. La muestra incluyó a todas las pacientes intervenidas por cáncer de mama a las que se realizaron técnicas oncológicas conservadoras y radicales, así como, cirugía plástica. Fueron analizadas variables demográficas, clínicas y terapéuticas. Se utilizaron los procedimientos aritméticos y tabulares de la estadística descriptiva. Se mostraron las variables cuantitativas como promedios y desviación estándar, los datos cualitativos como frecuencias y porcentajes. Resultados: la edad media fue de 45 años, con una mínima de 26 años y una máxima de 67. En las pacientes sin deformidad mamaria previa se aplicaron tratamientos radicales, conservadores, reconstrucción con cirugía ahorradora de piel y mastoplastias con mínimas incisiones. En las pacientes con deformidades mayores el tratamiento que predominó fue conservador y las reconstrucciones con mastoplastias. Los estadios tumorales que prevalecieron fueron los T2N1M0 y T1N1M0. El mayor número de complicaciones se observó en las pacientes sometidas a cirugía ahorradora de piel y en aquellas con tratamientos radicales. Conclusiones: la cirugía oncoplástica es una alternativa de tratamiento quirúrgico que actualmente se emplea con más frecuencia en las pacientes con cáncer de mama. Se obtienen resultados similares a los de la cirugía convencional en cuanto a incidencia de complicaciones, recidivas y muerte.

ABSTRACT Background: plastic surgery helps to improve the quality of life of patients with breast cancer. Breast reconstruction has evolved not only in aesthetic matters, but also in favor of achieving less morbidity in each patient affected. Objective: to describe the results obtained with the application of oncoplastic techniques in patients with breast cancer. Method: a descriptive study of a series of 41 patients was carried out at the Camilo Cienfuegos Provincial General Hospital in Sancti Spíritus from March 2018 to October 2020. The sample included all the patients operated on for breast cancer in which techniques were performed. Conservative and radical oncology, as well as, plastic surgery. Demographic, clinical and therapeutic variables were analyzed. The arithmetic and tabular procedures of descriptive statistics were used. Quantitative variables were shown as means and standard deviation. Qualitative data such as frequencies and percentages. Results: the mean age was 45 years, with a minimum of 26 years and a maximum of 67. In patients without previous breast deformity, radical and conservative treatments, reconstruction with skin-sparing surgery and mastoplasties with minimal incisions were applied. In patients with major deformities, the predominant treatment was conservative and reconstructions with mastoplasties. The tumor stages that prevailed were T2N1M0 and T1N1M0. The highest number of complications was observed in patients undergoing skin-sparing surgery and in those with radical treatments. Conclusions: oncoplastic surgery is an alternative surgical treatment that is currently used more frequently in patients with breast cancer. Similar results are obtained to conventional surgery in terms of incidence of complications, recurrences and death.
