The Effect of the Team Members Teaching Design vs. Regular Lectures method on the Self-efficacy of the Multiple sclerosis Patients in Iran. Randomised Controlled Trial / El efecto del diseño de enseñanza colaborativa frente al método de clases regulares sobre la autoeficacia de los pacientes con esclerosis múltiple en Irán. Ensayo Controlado Aleatorizado / O efeito do design de ensino colaborativo versus método de aula regular na autoeficácia de pacientes com esclerose múltipla no Irã. Teste controlado e aleatório

Objective. This study was conducted with the aim of the effect of team members teaching design (TMTD) vs. regular Lectures method on the self-efficacy of the multiple sclerosis patients. Methods. This research is a randomized controlled trial study. In this study, 48 multiple sclerosis persons of members of Jahrom MS Society participated. The persons were selected by simple random sampling and then divided into three groups of: TMTD (n=16), regular lecture method (n=16), and control (n=16), by random allocation method. In the intervention groups, six training sessions were held twice a week; control group did not receive education. Data was collected by the MS self-efficacy questionnaire of Rigby et al. in the before, immediately and one month after the intervention. Results. Patients in three intervention and control groups were similar in terms of demographic variables. The results of the repeated measurement test before, immediately and one month after the intervention showed that the mean of the all dimensions of self-efficacy in two intervention groups had increased significantly (p<0.05). While these changes were not significant in the control group (p ≥ 0.05). Also, there was a significant difference in the mean of the all dimensions of self-efficacy between the intervention groups of TMTD and regular lectures. Conclusion. Based on the findings, TMTD compared to regular lectures method had a more significant effect on improving the self-efficacy of multiple sclerosis patients. Therefore, it is recommended that nursing use this educational approach to increase patients' self-efficacy.

Objetivo. Determinar el efecto del diseño de la enseñanza colaborativa de los miembros del equipo (En inglés: Team Members Teaching Design -TMTD) frente al método de las clases regulares sobre la autoeficacia de los pacientes con esclerosis múltiple (EM).Métodos. Ensayo controlado aleatorizado realizado con la participación de 48 personas con esclerosis múltiple afiliados a la Sociedad de Esclerosis Múltiple de Jahrom (Iran), que fueron seleccionados por muestreo aleatorio simple y luego asignados en forma randomizada en tres grupos, dos de intervención: TMTD (n=16) y método de clases regulares (n=16), y un grupo control (n=16). En los grupos de intervención se impartieron seis sesiones educativas (dos por semana); mientras que el grupo control no recibió educación.

O TMTD comparado ao método de aula regular teve melhor efeito no aumento da autoeficácia dos pacientes com EM. Portanto, sugere-se que a enfermagem utilize essa abordagem educativa para aumentar a autoeficácia dos pacientes.

Lipectomia e lipoaspiração seriadas para manejo de síndrome de Madelung: A respeito de um caso / Serial lipectomy and liposuction for management of Madelung syndrome: About a case

A doença de Madelung é caracterizada pelo acúmulo simétrico e difuso de tecido adiposo com crescimento tumoral lento e progressivo. Neste relato de caso, um paciente portador dessa síndrome foi atendido no Hospital das Clínicas, em Recife, PE, com o objetivo de realizar uma redução do conteúdo lipomatoso através de lipectomia. O paciente apresentava volumosas massas de tecido adiposo elástico ao redor do pescoço e região supraclavicular e a proposta terapêutica consistiu em uma cirurgia em dois tempos, com lipoaspiração e lipectomia cervical anterior, seguida de lipoaspiração e lipectomia cervical posterior. Antes da cirurgia, foi solicitado um parecer cardiológico, que indicou um risco intermediário, mas não contraindicou o procedimento. Após 4 dias da cirurgia, o paciente apresentou equimoses e edema periférico na ferida operatória cervical, porém estava assintomático. As técnicas de lipectomia e lipoaspiração são consideradas os métodos de tratamento mais eficazes para a doença de Madelung. No entanto, a escolha da cirurgia deve ser baseada em uma avaliação abrangente da gravidade da doença, localização da massa e expectativas do paciente, uma vez que ambas as técnicas possuem vantagens e desvantagens.

Madelung's disease is characterized by the symmetric and diffuse accumulation of adipose tissue with slow and progressive tumor growth. In this case report, a patient with this syndrome was treated at Hospital das Clínicas, in Recife, PE, to reduce the lipomatous content through a lipectomy. The patient presented large masses of elastic adipose tissue around the neck and supraclavicular region and the therapeutic proposal consisted of a two-stage surgery, with liposuction and anterior cervical lipectomy, followed by liposuction and posterior cervical lipectomy. Before surgery, a cardiological opinion was requested, which indicated an intermediate risk but did not contraindicate the procedure. Four days after surgery, the patient presented bruises and peripheral edema in the cervical surgical wound but was asymptomatic. Lipectomy and liposuction techniques are considered the most effective treatment methods for Madelung disease. However, the choice of surgery should be based on a comprehensive assessment of the severity of the disease, location of the mass, and patient expectations, as both techniques have advantages and disadvantages.

Neoplasia endócrina múltiple y enfermedad inflamatoria intestinal de inicio muy temprano. Una asociación inesperada / Multiple endocrine neoplasia and very early onset in flammatory bowel disease. An unexpected association

Resumen La enfermedad inflamatoria intestinal de inicio muy temprano (VEOIBD) es una entidad rara en pediatría. Es conocida su asociación con inmunodeficiencias prima rias de origen monogénico. Presentamos el caso de una paciente con diagnóstico de VEOIBD a quien se le realizó una secuenciación masiva del exoma. El resultado del estudio permitió identificar una variante patogénica en el proto oncogen RET, asociada con enfermedad neoplasia endocrina múltiple tipo 2A. No hay reportes de asociación de variantes en el proto oncogen RET con VEOIBD. No se puede adjudicar la presencia de estas dos entidades clínicas a una única causa genética.

Abstract Very early onset inflammatory bowel disease (VEOI BD) is a rare entity in pediatrics. Its association with pri mary immunodeficiencies of monogenic origin is known. We present the case of a patient diagnosed with VEOIBD who underwent massive paralleled exome sequencing. The result of the study showed a pathogenic variant in the RET proto-oncogene, associated with multiple endo crine neoplasia type 2A disease. There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause.

The quality of life of people with multiple sclerosis in Portugal

Introduction: Multiple sclerosis significantly affects the quality of life of those suffering from this specific condition. Objective: To assess the quality of life of people with multiple sclerosis and analyse the correlation between the disease and its associated effects and different sociodemographic, clinical, and functional variables. Materials and Methods: An observational, cross-sectional, descriptive-correlational and quantitative study conducted using a non-probabilistic convenience sample composed of 70 patients suffering from multiple sclerosis registered with the Multiple Sclerosis Association of the Central Region of Portugal. The data collection protocol included sociodemographic and clinical questions, the Family Apgar Scale, and the Barthel Index. Descriptive and inferential statistics were used to process the data. Data collection took place between April and July 2021. Results: The majority of participants reported a moderate overall quality of life (M=51,78 ± 24,09). Higher scores were observed in the social relationships and environmental health domains, while lower scores were recorded for the physical domain. Better quality of life was found to be positively associated with being under 45 years old, having higher educational qualifications, living in functional families, and experiencing greater functional independence in activities of daily living. Discussion: The variables with the strongest association were those capable of influencing the physical and social domains. Those variables explained 59.00% and 53.00% of the variability. Conclusions: These results indicate that people with multiple sclerosis have a compromised quality of life, highlighting the need for new strategies focusing on early diagnosis and effective preventive interventions meant to improve quality of life across all its domains.

Diagnóstico de malformación del desarrollo cortical en embarazo gemelar monocorial: reporte de caso / Diagnosis of malformation of the cortical development in a monochorial twin pregnancy: case report

Introducción: Las malformaciones del desarrollo cortical se deben a alteraciones en la migración del neuroblasto durante la formación de la corteza cerebral. Se desconoce su frecuencia en embarazos monocoriales. Objetivo: Reportar el caso de un embarazo monocorial con diagnóstico de malformación del desarrollo cortical en uno de los fetos y revisar la literatura referente a su diagnóstico y pronóstico. Método: Mujer de 19 años, embarazo monocorial biamniótico de 26 semanas, que acudió con estudio ecográfico y resonancia fetal que evidenció en uno de los fetos asimetría de los hemisferios cerebrales, hipoplasia de la cisura de Silvio izquierda con simplificación del patrón giral por focos de paquigiria y polimicrogiria, con confirmación posnatal de alteración en la migración neuronal asociada a hipoplasia vermiana. Resultados: Se encontraron en la literatura tres casos de embarazo múltiple monocorial con trastorno de la migración neuronal con recién nacidos vivos. Los hallazgos más comunes fueron microcefalia, lisencefalia e hipoplasia cerebelosa. Conclusiones: El diagnóstico prenatal del trastorno de la migración neuronal se realiza con ecografía y resonancia fetal. La más frecuente es la alteración de la migración neuronal tipo II. El pronóstico depende del tipo de alteración; sin embargo, la mayoría de los casos presentan trastornos epileptiformes con alteraciones del neurodesarrollo.

Introduction: Malformations of cortical development are the result from alterations in the neuroblast migration during the cerebral cortex formation. Its frequency in monochorial multiple pregnancies remains unknown. Objective: To report a case of monochorial multiple pregnancy with diagnosis of malformation of the cortical development in one of the fetuses. In addition, to review the literature regarding the diagnosis and prognosis of this entity. Method: A 19-year-old female with a monochorial diamniotic pregnancy of 26 weeks gestation, arrived with an ultrasound anatomy scan visit, and fetal magnetic resonance imaging, we detected asymmetry in the cerebral hemispheres one of the fetuses, hypoplasia of the left sulcus of Sylvius with simplification of the gyrus pattern due to clusters of pachygyria and polymicrogyria. Those findings were confirmed afterbirth, with a definite diagnosis of neuronal migration disorder associated with vermian hypoplasia. Results: Three cases of monochorial pregnancy with neuronal migration disorder with live newborn, common findings like microcephaly, lissencephaly and vermian hypoplasia. Conclusions: Prenatal diagnosis with neuronal migration disorder is done via ultrasound and magnetic resonance imaging. Neuronal migration disorders type II are the most common of them. Prognosis depends on the type of disorder; however, most patients have epileptiform activity and neurodevelopment impairment.

Causas Múltiplas de Morte Associadas à Parada Cardiorrespiratória Pediátrica de 1996 a 2019 no Brasil / Multiple Causes of Death Associated with Pediatric Cardiopulmonary Arrest from 1996 to 2019 in Brazil

Resumo Fundamento: Em pediatria, a parada cardiorrespiratória (PCR) está associada a alta mortalidade e graves sequelas neurológicas. Informações sobre as causas e mecanismos de morte abaixo de 20 anos poderiam fornecer subsídios teóricos para a melhoria da saúde de crianças e adolescentes. Objetivos: Realizar uma análise populacional das taxas de mortalidade por causas primárias e múltiplas de morte abaixo de 20 anos, em ambos os sexos, no período de 1996 a 2019, no Brasil, e identificar a frequência com que a PCR foi registrada nas declarações de óbito (DOs) desses indivíduos e os locais de ocorrência dos óbitos, a fim de promover estratégias para melhorar a prevenção de mortes. Método: Estudo ecológico de séries temporais de óbitos em indivíduos menores de 20 anos, no período de 1996 a 2019, avaliando as taxas de mortalidade (TMs) e a mortalidade proporcional (MP) por causa básica de morte. Foram analisados os percentuais de PCR registrados em qualquer linha da DO e o local de ocorrência dos óbitos. Foram calculadas as TMs por 100 mil habitantes e a MP por causa básica de morte nos menores de 20 anos segundo sexo e faixa etária, os percentuais de óbito por causas básicas por faixa etária quando a PCR foi descrita em qualquer linha das Partes I e II da DO, e o percentual de óbitos por causas básicas segundo o local de ocorrência. Os dados foram retirados do DATASUS, IBGE e SINASC. Resultados: De 1996 a 2019, ocorreram 2.151.716 óbitos de menores de 20 anos, no Brasil, gerando uma taxa de mortalidade de 134,38 por 100 mil habitantes. A taxa de óbito foi maior entre os recém-nascidos do sexo masculino. Do total de óbitos, 249.334 (11,6%) tiveram PCR registrada em qualquer linha da DO. Especificamente, a PCR foi registrada 49.178 vezes na DO na faixa etária entre 1 e 4 anos e em 88.116 vezes entre 29 e 365 dias, correspondendo, respectivamente, a 26% e 22% dos óbitos nessas faixas etárias. Essas duas faixas etárias apresentaram as maiores taxas de PCR registradas em qualquer linha da DO. As principais causas básicas de óbito quando a PCR foi registrada na sequência de óbitos foram doenças respiratórias, hematológicas e neoplásicas. Conclusão: As causas perinatais e externas foram as principais causas de morte, com maior TM nos menores de 20 anos no Brasil de 1996 a 2019. Quando consideradas as causas múltiplas de morte, as principais causas primárias associadas à PCR foram as doenças respiratórias, hematológicas e neoplásicas. A maioria dos óbitos ocorreu no ambiente hospitalar. Melhor compreensão da sequência de eventos nesses óbitos e melhorias nas estratégias de ensino em ressuscitação cardiopulmonar pediátrica são necessárias.

Abstract Background: In pediatrics, cardiopulmonary arrest (CPA) is associated with high mortality and severe neurologic sequelae. Information on the causes and mechanisms of death below the age of 20 years could provide theoretical support for health improvement among children and adolescents. Objectives: To conduct a population analysis of mortality rates due to primary and multiple causes of death below the age of 20 years in both sexes from 1996 to 2019 in Brazil, and identify the frequency in which CPA was recorded in the death certificates (DCs) of these individuals and the locations where the deaths occurred, in order to promote strategies to improve the prevention of deaths. Method: Ecological time-series study of deaths below the age of 20 years from 1996 to 2019, evaluating the mortality rates (MRs) and proportional mortality (PM) by primary cause of death. We analyzed the percentages of CPA recorded in any line of the DC and the location where the deaths occurred. We calculated the MRs per 100,000 inhabitants and the PM by primary cause of death under the age of 20 years according to sex and age group, the percentages of death from primary causes by age group when CPA was described in any line of Parts I and II of the DC, and the percentage of deaths from primary causes according to their location of occurrence. We retrieved the data from DATASUS, IBGE, and SINASC. Results: From 1996 to 2019, there were 2,151,716 deaths below the age of 20 years in Brazil, yielding a mortality rate of 134.38 per 100,000 inhabitants. The death rate was highest among male neonates. Of all deaths, 249,334 (11.6%) had CPA recorded in any line of the DC. Specifically, CPA was recorded in 49,178 DCs between the ages of 1 and 4 years and in 88,116 of those between the ages of 29 and 365 days, corresponding, respectively, to 26% and 22% of the deaths in these age groups. These two age groups had the highest rates of CPA recorded in any line of the DC. The main primary causes of death when CPA was recorded in the sequence of death were respiratory, hematologic, and neoplastic diseases. Conclusion: Perinatal and external causes were the primary causes of death, with highest MRs under the age of 20 years in Brazil from 1996 to 2019. When multiple causes of death were considered, the main primary causes associated with CPA were respiratory, hematologic, and neoplastic diseases. Most deaths occurred in the hospital environment. Better understanding of the sequence of events in these deaths and improvements in teaching strategies in pediatric cardiopulmonary resuscitation are needed.

Use of potentially inappropriate medications and medications of concern in older adults with multiple myeloma / Utilização de medicamentos potencialmente inapropriados e medicamentos que requerem cautela em idosos com mieloma múltiplo

Objetivo: Analisar o uso de medicamentos potencialmente inapropriados (MPIs) e o uso de medicamentos usados em terapia de suporte que requerem cautela em idosos com câncer (MTSRCICs), determinando os fatores associados. Visou-se também determinar a concordância entre os critérios explícitos empregados na identificação de MPI. Metodologia: Estudo transversal com indivíduos com mieloma múltiplo (MM), idade ≥ 60 anos em tratamento ambulatorial. Os MPI foram identificados de acordo com os critérios AGS Beers 2019, PRISCUS 2.0 e o Consenso Brasileiro de Medicamentos Potencialmente Inapropriados (CBMPI). Os MTSRCIC foram definidos de acordo com a National Comprehensive Cancer Network. Os fatores associados ao uso de MPI e MTSRCIC foram identificados por regressão logística múltipla. O grau de concordância entre os três critérios explícitos empregados no estudo foi mensurado pelo coeficiente kappa Cohen. Resultados: As frequências de MPI foram 52,29% (AGS Beers 2019), 62,74% (CBMPI), 65,36% (PRISCUS 2.0) e 52,29% (MTSRCICs). As concordâncias entre AGS Beers 2019 com PRISCUS 2,0 e com CBMPI foram altas, enquanto a concordância entre CBMPI e PRISCUS 2.0 foi excelente. No modelo final de regressão logística polifarmácia foi associada positivamente ao uso de MPI por idosos para os três critérios explícitos utilizados, além de associado à utilização de MTSRCICs. Conclusões: A frequência do uso de MPI e de MTSRCIC foi elevada. A concordância em relação ao uso de MPI entre os critérios AGS Beers 2019, CBMPI e PRISCUS 2.0 foi alta ou excelente. A polifarmácia apresentou associação independente e positiva com uso de MPIs e de MTSRCICs por pacientes idosos com MM. (AU)

Objectives: To analyze the use of potentially inappropriate medications (PIMs) and medications used in supportive therapy that require caution in older adults with cancer, in addition to determining associated factors the agreement between criteria sets used to identify PIMs. Methods: This cross-sectional study included individuals with multiple myeloma aged ≥ 60 years who were undergoing outpatient treatment. PIMs were identified according to American Geriatric Society Beers 2019, PRISCUS 2.0, and Brazilian Consensus on Potentially Inappropriate Medicines criteria. Medications of concern were defined according to National Comprehensive Cancer Network criteria. Factors associated with the use of PIMs and medications of concern were identified using multiple logistic regression. The degree of agreement between the 3 criteria sets was measured using Cohen's kappa coefficient. Results: The frequency of PIM use was 52.29% according to American Geriatric Society Beers criteria, 62.74% according to Brazilian Consensus criteria, and 65.36% according to PRISCUS criteria, while 52.29% of the patients were using medications of concern. Agreement between American Geriatric Society Beers, PRISCUS, and Brazilian Consensus criteria was high, while it was excellent between Brazilian Consensus and PRISCUS criteria. In the final logistic regression model, polypharmacy was associated with PIM use according to each criteria set, as well as the use of medications of concern. Conclusions: The frequency of PIMs and medications of concern was high. Agreement about PIM use between the American Geriatric Society Beers, Brazilian Consensus, and PRISCUS criteria was high or excellent. There was an independent association between polypharmacy and the use of PIMs and medications of concern by older patients with multiple myeloma. (AU)

Cáncer Gástrico Bifocal con Linfonodos Negativos en un Paciente con Cirrosis Hepática / Bifocal Gastric Cancer with Negative Lymph Nodes in a Hepatic Cirrhosis Patient

El cáncer gástrico (CG), es la primera causa de muerte por cáncer, en hombres, y la tercera en mujeres, en Chile. No obstante ello, el CG bifocal (CGB) es una situación poco frecuente. El objetivo de este manuscrito fue reportar un caso de CGB, con linfonodos negativos en un paciente con cirrosis hepática, que fue intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Caso clínico: Hombre de 74 años diabético, hipertenso, insuficiente cardíaco y cirrótico; portador de CGB (subcardial y antro-pilórico), diagnosticado por endoscopia y con confirmación histológica de ambas lesiones; operado en Clínica RedSalud Mayor Temuco en septiembre de 2023. En el intraoperatorio se verificó además la coexistencia de una lesión de aspecto metastásico en el segmento III del hígado, y adhesión de la región antro-pilórica a la vesícula biliar. Se realizó gastrectomía total, linfadenectomía D2, esófago-yeyuno anastomosis término-lateral, resección segmentaria hepática (segmento III) y colecistectomía. El paciente permaneció 6 días en la UCI debido a que desarrolló insuficiencia hepática (encefalopatía leve y ascitis). Se alimentó vía enteral por sonda naso-yeyunal. Posteriormente inició alimentación oral progresiva, la que fue bien tolerada. Completó 11 días de hospitalización en servicio médico-quirúrgico, donde mejoró actividad neurológica, hasta su alta domiciliaria. Actualmente, lleva dos meses desde su operación, se encuentra en buenas condiciones generales, y el Comité Oncológico decidió no dar quimioterapia adyuvante. Se presenta un caso inusual de CG de tipo bifocal, respecto de lo cual hay escasa información disponible. Se logró realizar cirugía con intención curativa en un paciente de alto riesgo, con un resultado exitoso.

SUMMARY: Gastric cancer (GC) is the first cause of death from cancer in men, and the third one in women, in Chile. However, a bifocal GC (BGC) is uncommon. The aim of this study was to report a case of CGB, with negative-lymph nodes in a patient with liver cirrhosis, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. Clinical case: A 74-year-old male patient with a medical history of diabetes, hypertension, congestive heart failure, and cirrhosis underwent surgical intervention for GC located in subcardial and antro- pyloric regions. The diagnosis was established via endoscopy and confirmed histologically. Surgery was performed at the RedSalud Mayor Temuco Clinic in September 2023. During intraoperative assessment, the coexistence of a lesion with metastatic-like characteristics in segment III of the liver was also verified, along with adhesions between the antro-pyloric region and the gallbladder. Surgical approach encompassed total gastrectomy, D2 lymphadenectomy, esophago-jejunostomy, segmental hepatic resection, and cholecystectomy. Subsequently, the patient required a six-day stay in ICU due to the development of hepatic insufficiency, characterized by mild encephalopathy and ascites. Enteral nutrition was administered via a naso-jejunal tube, followed by a gradual transition to oral feeding, which was well-tolerated. The patient completed an 11-day hospitalization period in the medical-surgical ward, during which his neurological function improved significantly, resulting in his discharge. At present, 2 months post-surgery, the patient remains in satisfactory general health, and the Oncology Committee decided not to proceed with adjuvant chemotherapy. This case represents a rare instance of bifocal GC, for which there is limited available literature. Surgical intervention with curative intent was successfully carried out in a high-risk patient, yielding a positive outcome.

Use of CAR-T cells for the treatment of relapsed and refractory multiple myeloma: a systematic review / Uso de células CAR-T no tratamento de mieloma múltiplo recidivado e refratário: uma revisão sistemática

A systematic review of published articles based on randomized clinical trials was conducted to ascertain the efficacy or perspective of using CAR-T cell therapy for refractory multiple myeloma. The PubMed database was searched with the combination of terms "multiple myeloma", "refractory multiple myeloma", "CAR T-cell", and the PRISMA criteria were followed. Of the 78 articles found, only 5 were selected. The studies used different treatment protocols and four different types of CAR-T cells. All studies obtained interesting results in terms of increased progression-free survival and negative minimal residual disease responses. Some authors detected an expansion of CAR-T cells and noted dose-dependent relationship between treatment effectiveness and serum BCMA levels. Although the results were promising, a small number of patients still relapsed a few months after CAR-T cell infusion. Therefore, this new line of therapy should be further investigated, as it significantly increases progression-free survival and improves quality of life.

Uma revisão sistemática de artigos publicados com base em ensaios clínicos randomizados foi realizada para verificar a eficácia ou perspectiva do uso da terapia com células CAR-T para mieloma múltiplo refratário. Foi pesquisada a base de dados PubMed com a combinação dos termos "multiple myeloma", "refratory multiple myeloma", "CAR T-cell" e foram seguidos os critérios PRISMA. Dos 78 artigos encontrados, apenas 5 foram selecionados. Os estudos utilizaram diferentes protocolos de tratamento e quatro tipos diferentes de células CAR-T. Todos os estudos obtiveram resultados interessantes em termos de aumento da sobrevida livre de progressão e respostas negativas à doença residual mínima. Alguns autores detectaram uma expansão das células CAR-T e observaram uma relação dose-dependente entre a eficácia do tratamento e os níveis séricos de BCMA. Embora os resultados tenham sido promissores, um pequeno número de pacientes ainda apresentou recaída alguns meses após a infusão de células CAR-T. Portanto, esta nova linha de terapia deve ser mais investigada, pois aumenta significativamente a sobrevida livre de progressão e melhora a qualidade de vida.

Ayuno intermitente y restricción calórica como tratamiento coadyuvante en enfermedad de Alzheimer y esclerosis múltiple / Intermittent Fasting and Caloric Restriction as an Adjunctive Treatment in Alzheimer's Disease and Multiple Sclerosis

Las enfermedades de Alzheimer y esclerosis múltiple son neurodegenerativas, con tratamientos complejos y de costos elevados, orientados a disminuir la progresión de la sintomatología. Sin embargo, a causa de la falta de terapias adecuadas y de los posibles efectos adversos ocasionados por tratamientos de primera línea, es necesario implementar mejores abordajes terapéuticos complementarios que no produzcan mayores efectos secundarios y mejoren la sintomatología de dichas patologías. La restricción calórica y el ayuno intermitente han demostrado ser estrategias novedosas y beneficiosas en enfermedades neurodegenerativas, a través de mecanismos inmunitarios, metabólicos y fisiológicos. Con el objetivo de determinar el uso del ayuno intermitente y la restricción calórica como tratamiento coadyuvante en esclerosis múltiple y enfermedad de Alzheimer, se realizó una revisión narrativa de artículos originales en revistas científicas, en idiomas inglés y español, de 2018 a 2022. El uso de la restricción calórica y ayuno intermitente han generado cambios positivos produciendo disminución de estados proinflamatorios, estrés oxidativo y envejecimiento. Se consideran abordajes que modulan la progresión de la enfermedad y mejoran la función cognitiva por vías de señalización de monofosfato de adenosina cinasa, factor de crecimiento similar a la insulina y la enzima sirtuina, generando un efecto neuroprotector.

Alzheimer's disease and multiple sclerosis are neurodegenerative disorders with expensive and complex treatments aimed at reducing the progression of symptoms. However, due to the lack of adequate therapies and the possible adverse effects caused by first-line treatments, it's necessary to implement better complementary therapeutic approaches that do not produce major side effects and improve symptoms. Caloric restriction and intermittent fasting have been shown to be novel and beneficial strategies in neurodegenerative diseases, through immune, metabolic, and physiological mechanisms. To determine the use of intermittent fasting and caloric restriction as a new treatment in multiple sclerosis and Alzheimer's disease, a narrative review of original articles in both national and international scientific journals, in English and Spanish languages with no greater obsolescence than five years. The use of caloric restriction and intermittent fasting have generated positive changes, producing a decrease in pro-inflammatory states, oxidative stress, and aging. Approaches that modulate disease progression and improve cognitive function of adenosine monophosphate kinase, insulin-like growth factor, and sirtuin enzyme pathways are considered, generating a neuroprotective effect.

CircRERE promotes proliferation,migration and invasion of human multiple myeloma cell lines by regulating miR-128-3p/WEE1 axis / 基础医学与临床

Objective To investigate the impacts of circular RNA RERE(circRERE)on proliferation,migration and invasion of human multiple myeloma(MM)cell lines by regulating microRNA(miR)-128-3p/serine/threo-nine protein kinase(WEE1)axis.Methods Normal plasma cells(nPCs)isolated from peripheral blood of healthy subjects and human MM cell lines(U266,RPMI-8226,NCI-H929,LP-1)were cultured.The expressions of circRERE and miR-128-3p were detected by RT-qPCR.The expression of WEE1 was detected by Western blot.After transfection,RPMI-8226 cells were divided into control group(without transfection),sh-circRERE group,sh-NC group,miR-128-3p inhibitor group,inhibitor-NC group,sh-circRERE+inhibitor-NC group and sh-circRERE+miR-128-3p inhibitor group.MTT assay and 5-ethynyl-2′-deoxyuridine(EdU)im-munofluorescence staining microscopy were used to detect the proliferation.Migration and invasion were exam-ined by scratch healing experiment as well as Transwell chamber assay.The targeting relationship between miR-128-3p and circRERE or WEE1 was verified though dual-luciferase reporter gene assay.Results Com-pared with nPCs,the expressions of circRERE and WEE1 in MM cells(RPMI-8226,U266,NCI-H929,LP-1)were increased,and the expression of miR-128-3p was decreased(P＜0.05).Compared with the con-trol group,the proliferation rate,proportion of EdU positive cells,the healing rate of the scratch trauma and the number of invasion of the RPMI-8226 cells in sh-circRERE group were decreased(P＜0.05).However,miR-128-3p inhibitor group showed an opposite result and the difference was statistically significant(P＜0.05).miR-128-3p inhibitor significantly inhibited the effects of sh-circRERE on the proliferation,mi-gration and invasion of RPMI-8226 cells(P＜0.05).Dual luciferase reporter gene experiments showed that circRERE/miR-128-3p and miR-128-3p/WEE1 had a targeting relationship.Conclusions CircRERE may promote proliferation,migration and invasion of RPMI-8226 cells,potentially with a mechanism of regulating miR-128-3p/WEE1 axis.

Establishment of a nomogram model to predict sepsis in patients with multiple trauma / 中华急诊医学杂志

Objective:To explore the risk factors of sepsis in patients with multiple trauma and construct a nomogram prediction model.Methods:The data of patients with multiple injuries admitted to the emergency intensive care unit (EICU) of the General Hospital of Ningxia Medical University from January 2021 to April 2022 were respectively collected. Inclusion criteria: (1) meet the diagnostic criteria for multiple injuries; (2) the time from injury to admission ≤ 24 hours; (3) age>18 years old; (4) all examination or rescue measures were approved by the patient or the patient's family; (5) the patient's clinical data were complete. The patients were divided into sepsis group and non-sepsis group according to the definition of Sepsis 3.0 at the 28-day of EICU hospitalization. The receiver operating characteristic curve was drawn. Logistic regression analysis was applied to determine the independent predictors for sepsis, and the nomogram was constructed.Results:A total of 291 patients were included, including 102 in the sepsis group and 189 in the non-sepsis group. Multivariate logistic analysis revealed that age, acute physiology and chronic health status score (APACHE) Ⅱ, Glasgow Coma Scale (GCS), injury severity score (ISS), sequential organ failure assessment (SOFA) within 24 hours after admission, blood transfusion frequency, the application of norepinephrine, mechanical ventilation, pathogenic culture results, and history of diabetes were independent factors influencing the occurrence of sepsis. A nomogram model was constructed by combining these variables (AUC=0.913, 95% CI: 0.847-0.942), and the model had a good fitting calibration curve. Conclusions:The nomogram constructed by age, APACHE-Ⅱ, GCS score, SOFA score, ISS score, number of blood transfusions, mechanical ventilation, norepinephrine drug use, pathogenic culture and diabetes has a good predictive value for sepsis in patients with multiple trauma in the later stage, which is worth promoting.

Study on the relationship between comorbidities of chronic diseases,phase angle,and muscle mass decline related to sarcopenia in the elderly / 上海交通大学学报（医学版）

Objective·To explore the correlation between comorbidities of chronic non-communicable diseases(chronic diseases),phase angle(PhA),and muscle mass decline associated with sarcopenia in the elderly,and the predictive value of chronic disease comorbidities and PhA in muscle mass decline in the elderly.Methods·By retrospectively screening inpatients aged≥60 years who were admitted to the Department of Geriatrics,Renji Hospital,Shanghai Jiao Tong University School of Medicine from August 1,2018 to July 31,2019,basic information and medical history of the patients(gender,age,number of medications used,number of comorbidities,presence of osteoporosis,smoking history,etc.)were collected,as well as laboratory examination indicators(hemoglobin,albumin,serum creatinine,serum uric acid,ferritin,vitamin D,triacylglycerol,total cholesterol,high-density lipoprotein,low-density lipoprotein,etc.).The age-adjusted Charlson comorbidity index(aCCI)was calculated.The InBody S10 bioelectrical impedance body composition detector was used to test the body composition.Body mass index(BMI),skeletal muscle mass index(SMI),and PhA were collected.Some patients underwent measurement of grip strength.Muscle mass decline was diagnosed by using the SMI values recommended by the 2019 Asian Working Group for Sarcopenia(AWGS)(≤7.0 kg/m2 for males and≤5.7 kg/m2 for females).According to the measured SMI values,patients were divided into a group with normal muscle mass and a group with muscle mass decline.Univariate and multivariate Logistic analyses were employed to investigate the risk factors associated with muscle mass decline related to sarcopenia in the elderly.Additionally,the receiver operator characteristic(ROC)curve and the area under the curve were utilized to predict the significance of these factors in muscle mass decline.Results·A total of 359 chronic disease patients were enrolled,including 226 males and 133 females.There were 241 cases in the normal muscle mass group and 118 cases in the muscle mass decline group.The incidence of muscle mass decline related to sarcopenia in the elderly was 32.9%.The univariate Logistic regression analysis showed that age(OR=1.036,95%CI 1.013?1.060),comorbidities(OR=1.117,95%CI 1.025?1.217),aCCI(OR=1.123,95%CI 1.031?1.222),and high-density lipoprotein(OR=3.688,95%CI 2.065?6.622)were positively correlated with the risk of muscle mass decline in the elderly.BMI(OR=0.514,95%CI 0.443?0.597),PhA(OR=0.195,95%CI 0.126?0.303),hemoglobin(OR=0.984,95%CI 0.972?0.996)and triacylglycerol(OR=0.606,95%CI 0.424?0.866)were negatively correlated with the risk of muscle mass decline in the elderly.Multivariate Logistic regression model indicated that PhA(OR=0.338,95%CI 0.119?0.959)and BMI(OR=0.634,95%CI 0.476?0.844)were negatively correlated with the risk of muscle mass decline in elderly.The area under the ROC curve for predicting muscle mass decline related to sarcopenia in elderly by using BMI and PhA was 0.893(95%CI 0.855?0.931)and 0.786(95%CI 0.736?0.837),respectively.The sensitivity was 0.724 and 0.676,respectively.The specificity was 0.916 and 0.762,respectively.When BMI combined with PhA predicted muscle mass decline in the elderly,the area under the ROC curve was 0.917(95%CI 0.883?0.951).The sensitivity was 0.867,and the specificity was 0.860.Conclusion·aCCI is correlated with muscle mass decline associated with sarcopenia in the elderly.As BMI and PhA decrease,the risk of muscle mass decline in the elderly increases.The combination of BMI and PhA has a high predictive value in muscle mass decline in the elderly.No predictive value of chronic diseases comorbidities in muscle mass decline related to sarcopenia in the elderly is found.

The effects of cannabidiol on the expression of NLRP3 inflammasome following multiple cerebral concussions in rats / 神经解剖学杂志

Objective:To investigate the effects of cannabidiol(CBD)on the NOD-like receptor protein 3(NLRP3)inflammasome in the brains of rats with multiple cerebral concussions(MCC).Methods:Rats were subjec-ted to the MCC model and divided into Sham,MCC,vehicle(MCC+TW),CBD-L(10 mg/kg),and CBD-H(40 mg/kg)groups.Immunofluorescence double staining was used to observe changes in NLRP3 and microglial cells in the brain,and Western Blot was performed to detect the expression changes of the NLRP3 inflammasome.Results:A sig-nificant increase in lectin-positive microglial cells of the cortex with enlarged cell bodies and elevated immunofluores-cence intensity of NLRP3 in the activated microglial cells was revealed by immunofluorescence double staining following MCC(P＜0.05).The immunofluorescence intensity of NLRP3 in the activated microglial cells was downregulated by the administration of CBD,with a more pronounced effect observed in the CBD-H group compared to the CBD-L group(P＜0.05).The expression of NLRP3,caspase-1,and apoptosis-associated speck-like protein(ASC)in the cortex,hippocampus,and basal ganglia of rats following MCC was significantly increased,as shown by Western Blot analysis(P＜0.05),and cortical areas are more elevated.The expression of these proteins in different brain regions was reduced by CBD-10 and CBD-40 intervention(P＜0.05).Conclusion:Cannabidiol can reduce the inflammatory response of multiple cerebral concussions rats through NLRP3 inflammasome and protect nerve tissue.

Single-cell RNA sequencing reveals the heterogeneity of astrocytes / 中国组织工程研究

BACKGROUND:Astrocytes are the most abundant cells in the central nervous system,and various subsets of astrocytes are heterogeneous,performing a variety of special functions.Single-cell RNA sequencing(scRNA-seq)technology developed in recent years has extended our understanding of astrocyte heterogeneity from the perspective of transcriptome profiling. OBJECTIVE:To summarize the heterogeneity of scRNA-seq technology in different time and space,and pathological states and expand our knowledge of astrocyte heterogeneity on both molecular and functional levels. METHODS:The relevant articles on astrocyte heterogeneity and scRNA-seq were searched on PubMed,Elsevier,and CNKI databases.The search terms were"astrocytes,scRNA-seq,heterogeneity,Alzheimer disease,spinal cord injury,multiple sclerosis"in Chinese and English.Finally,74 articles were selected for viewing after screening according to inclusion criteria. RESULTS AND CONCLUSION:scRNA-seq studies related to the heterogeneity of astrocytes have shown that astrocyte is significantly heterogeneous across four aspects:species,developmental stage,central nervous system region,and pathological state.(1)Unique expression of certain genes occurs in astrocytes of different species,and the discovery of species-specific genes is beneficial for the translation of clinical studies.(2)During astrocyte development,differential gene expression emerged in the cellular subtypes identified at each stage,which further refined the cellular lineage of astrocytes and laid the foundation for the study of astrocyte developmental trajectories and mechanisms.(3)The discovery of differential gene expression allows regional localization of different astrocyte subpopulations and assists in the diagnosis and treatment of neurological diseases.(4)Astrocyte heterogeneity revealed by scRNA-seq can provide specific markers at the time of disease diagnosis and identify potential therapeutic targets.(5)The heterogeneity of astrocytes exists in many aspects,interacts with each other and is complex.The mechanisms of its generation,maintenance and transformation remain unclear.At present,molecular research on the single-cell level is still lacking.Linking transcriptionally defined astrocyte subpopulations to cellular activity,behavior and disease markers in real time remains one of the great challenges in the field.

Immunomodulatory effect of astragaloside IV on T cells of experimental autoimmune encephalomyelitis mice / 中国组织工程研究

BACKGROUND:In the initial stage of multiple sclerosis,central immune cells activate and release a large number of inflammatory factors,causing white matter demyelination and even involving gray matter neurons.The equilibrium of differentiation between different subsets of CD4+ T cells plays an important role in the progression of experimental autoimmune encephalomyelitis.The previous results of the research group showed that the active ingredient astragalus glycoprotein in astragalus can regulate the immune response in experimental autoimmune encephalomyelitis mice,and whether it has a regulatory effect on the differentiation of T cell subsets has not been determined. OBJECTIVE:To explore the therapeutic effects and immune regulatory mechanisms of astragaloside IV on experimental autoimmune encephalomyelitis mice. METHODS:Female C57BL/6 mice were divided into the normal control group,experimental autoimmune encephalomyelitis disease model group,and astragaloside IV treatment group(n=8 per group).Myelin oligodendrocyte glycoprotein peptides 35-55 were used for experimental autoimmune encephalomyelitis model induction in the last two groups.On day 10 to 28 after immunization,the astragaloside IV treatment group was treated with 40 mg/kg per day astragaloside IV intragastrically.Body weight and clinical scores of mice in each group were recorded from the immunization day to the 28th day.On the 28th day after immunization,the mouse spinal cord was taken and made into frozen sections for hematoxylin-eosin staining and Lux fast blue staining to observe pathological changes in the spinal cord.Percentage of splenic T cell subsets was detected using flow cytometry.Western blot assay was used to determine the protein expression of interferon-γ,interleukin-17 and interleukin-6 in the spinal cord.Levels of interferon-γ,interleukin-17,interleukin-6 and interleukin-4 in supernatants of cultured splenocytes were determined by ELISA. RESULTS AND CONCLUSION:(1)Compared with the experimental autoimmune encephalomyelitis disease model group,astragaloside IV could reduce the degree of weight loss in experimental autoimmune encephalomyelitis mice(P<0.05),ameliorate clinical symptoms(P<0.05),inhibit the infiltration of inflammatory cells and alleviate myelin loss(P<0.01,P<0.05).(2)Compared with the experimental autoimmune encephalomyelitis disease model group,astragaloside IV could inhibit the proportion of CD4+T cell subsets expressing interferon-γ(P<0.001)and interleukin-17(P<0.001),but increase percentages of CD4+ interleukin-10+(P<0.001)and CD4+ transforming growth factor-β+(P<0.01)T cell subsets.(3)Astragaloside IV could inhibit the expression of interferon-γ(P<0.05,P<0.01),interleukin-17(P<0.05,P<0.05),and interleukin-6(P<0.05,P<0.05)in the spinal cord and spleen,and up-regulate the expression of interleukin-4(P<0.01)in spleen.(4)These findings confirm that astragaloside IV alleviates clinical symptoms in experimental autoimmune encephalomyelitis mice,which may be related to regulating the splenic T cell subsets,therefore,inhibiting the infiltration of inflammatory cells into the center and reducing the demyelination.

The role and mechanism of TLRs/MyD88/NF-κB signaling pathway in multiple sclerosis / 中国组织工程研究

BACKGROUND:Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system mediated by T cells.The Toll-like receptors(TLRs)/myeloid differentiation factor 88(MyD88)/nuclear factor kappa-B(NF-κB)signaling pathway plays an important role in the development of the disease.Exploring the specific mechanism of the signaling pathway is essential for further treatment of the disease and improving the prognosis of patients. OBJECTIVE:To review the TLRs/MyD88/NF-κB signaling pathway and its role in multiple sclerosis/experimental autoimmune encephalomyelitis models,which provides new ideas and strategies for the treatment of multiple sclerosis by inhibiting the TLRs/MyD88/NF-κB signaling pathway. METHODS:The literature related to the topic from January 2002 to December 2022 was searched in CNKI,WanFang and PubMed databases.A total of 61 articles were finally included for analysis. RESULTS AND CONCLUSION:The TLRs/MyD88/NF-κB signaling pathway is an important pathway that triggers a pro-inflammatory immune response.The TLRs/MyD88/NF-κB signaling pathway plays an important role in the development of multiple sclerosis by regulating the antigen presentation of dendritic cells,destroying the integrity of the blood-brain barrier,and promoting the activation of T cells,B cells and microglia.By targeting TLRs,MyD88 and NF-κB molecules,inhibiting the activation or signal transduction of TLRs,MyD88 and NF-κB,and reducing the secretion of pro-inflammatory factors,multiple sclerosis can be treated.Animal studies have shown that active ingredients of traditional Chinese medicines,such as flavonoids and glycosides,and traditional Chinese medicine compound formulas,such as Buyang Huanwu Tang,can also treat experimental autoimmune encephalomyelitis by regulating the TLRs/MyD88/NF-κB signaling pathway,which points to the direction of searching for medicines targeting the TLRs/MyD88/NF-κB signaling pathway for the treatment of multiple sclerosis.

Relationship between blood indicators and course of nontraumatic osteonecrosis of femoral head in different stages:multiple logistic regression analysis / 中国组织工程研究

BACKGROUND:Up to now,there is no literature on the relationship between blood laboratory tests and the course of nontraumatic osteonecrosis of femoral head in different stages.It is necessary to further explore and analyze so as to better clarify the influencing factors of nontraumatic osteonecrosis of femoral head. OBJECTIVE:To analyze the relationship between blood laboratory indicators and the course of nontraumatic osteonecrosis of the femoral head by the Association Research Circulation Osseous(ARCO),thus exploring the influencing factors of blood laboratory indicators on the course of nontraumatic osteonecrosis of the femoral head. METHODS:This study used a retrospective study design.A total of 2 103 patients with osteonecrosis of the femoral head were retrieved from Wangjing Hospital of China Academy of Chinese Medical Sciences database,and 1 075 patients with nontraumatic osteonecrosis of the femoral head were ultimately included based on inclusion and exclusion criteria.Patient age,gender,body mass index,and blood laboratory test results were collected.Blood laboratory tests included low-density lipoprotein,total cholesterol,triglycerides,high-density lipoprotein,apolipoprotein β,apolipoprotein α1,uric acid,total protein quantitative,alkaline phosphatase,activated partial thromboplastin time,prothrombin time,prothrombin time International Normalized Ratio,prothrombin time activity,fibrinogen quantitative,coagulation time of thrombin,D-dimer,total iron binding capacity,and platelet count.The indicators of patients with different age groups and different ARCO stages were compared,and multiple Logistic regression analysis was applied to explore the influencing factors of ARCO stages in osteonecrosis of the femoral head. RESULTS AND CONCLUSION:(1)There were statistical differences in total cholesterol,uric acid,prothrombin time,prothrombin time International Normalized Ratio,and D-dimer among ARCO stages in the young group(P<0.05).Among young patients in ARCO stage II,total cholesterol levels were higher than those in ARCO stage III(P<0.05).Uric acid levels in ARCO stage IV were higher than those in ARCO stage II and III(P<0.05).Prothrombin time and prothrombin time International Normalized Ratio were shorter in ARCO stage IV and II than in ARCO stage III(P<0.05).D-dimer levels were higher in ARCO stage III and IV than in ARCO stage II(P<0.05).(2)There were statistically significant differences in high-density lipoprotein,coagulation time of thrombin,and D-dimer among ARCO stages in the middle-aged group(P<0.05).Among middle-aged patients in ARCO stage IV,high-density lipoprotein levels were higher than those in ARCO stages II and III(P<0.05).Coagulation time of thrombin was shorter in ARCO stage IV than in ARCO stage III(P<0.05).D-dimer levels were higher in ARCO stages IV than in ARCO stages II and III(P<0.05).(3)The uric acid,activated partial thromboplastin time,D-dimer,and platelet count in the elderly group showed statistically significant differences(P<0.05).The uric acid level in ARCO stage IV was higher than that in ARCO stage II and III patients in the elderly group(P<0.05),while the activated prothrombin time in ARCO stage II patients was shorter than that in ARCO stage III patients in the elderly group(P<0.05).The D-dimer level in ARCO stage III and IV patients was higher than that in ARCO stage II patients in the elderly group(P<0.05).The platelet count in ARCO stage IV was lower than that in ARCO stage III patients in the elderly group(P<0.05).(4)Multiple logistic regression analysis showed that total cholesterol and platelet count may be protective factors for course of nontraumatic osteonecrosis of the femoral head,while D-dimer,uric acid,overweight,and young and middle age may be risk factors for course of nontraumatic osteonecrosis of the femoral head.(5)It is indicated that total cholesterol,high-density lipoprotein,uric acid,prothrombin time,prothrombin time International Normalized Ratio,and D-dimer are statistically significant among patients with different ARCO stages.Total cholesterol and platelet count may be protective factors for the course of nontraumatic osteonecrosis of the femoral head,while D-dimer,uric acid,overweight,and middle-aged and young age groups may be hazard factors for the course of nontraumatic osteonecrosis of the femoral head.

Sepsis-induced thrombocytopenia-associated multiple organ failure / 中国小儿急救医学

Sepsis-induced thrombocytopenia-associated multiple organ failure（TAMOF）is a severe subtype of sepsis-related organ dysfunctions，which has high mortality and poor prognosis.The main clinical characteristics are thrombocytopenia caused by infection and multiple organ dysfunction.However，the exact molecular mechanism of TAMOF remains unclear.The current studies have shown ADAMTS-13，which is a von Willebrand factor lyase，plays an important role during the disease.Plasma exchange could be a treatment method，but still need more large-scale randomized controlled trials to verify.In the future，von Willebrand factor and ADAMTS-13 could become the therapeutic targets for new drug development.
