ABSTRACT

Anticarsia gemmatalis Hünber, 1818 is one of the main defoliating species in the soybean crop. Bacillus thuringiensis Berliner, 1915, is a bacterium used in the biological control of this pest species. Resistant populations and their sublethal effects caused by the use of the bacteria have already been reported; however, there are no studies on phenotypic plasticity in adulthood exposed to Bt-based bioinsecticide sub-doses. This study aimed to evaluate the morphometry of A. gemmatalis adults under laboratory conditions submitted to the Bt-based bioinsecticide Dipel® over the three generations. The body segments mensuread were width, length, and area of the anterior and posterior wings, the weight of the integument, chest, abdomen, wings, and the whole adult of males and females. Among the treatments, LC5 in the first generation and LC10 in the second generation were those with lower thresholds in relation to the weight of the chest and abdomen, considering the proportions of the body smaller than the females. The female's weight adulthood was reduced by 10% about males, and, only in the first generation. Males have larger body size and more pronounced phenotypic plasticity than females. Here, we demonstrate the first study assessing the phenotypic plasticity of A. gemmatalis adults.


Anticarsia gemmatalis Hünber, 1818 é uma das principais espécies desfolhadoras da cultura da soja. Bacillus thuringiensis Berliner, 1915, é uma bactéria utilizada no controle biológico dessa espécie de praga. Populações resistentes e seus efeitos subletais causados pelo uso da bactéria já foram relatados, no entanto, não há estudos sobre a plasticidade fenotípica na idade adulta exposta a subdoses de bioinseticida à base de Bt. Este trabalho teve como objetivo avaliar a morfometria de adultos de A. gemmatalis em condições de laboratório submetidos ao bioinseticida Dipel® ao longo de três gerações. Os segmentos corporais mensuráveis eram largura, comprimento e área das asas anterior e posterior, o peso do tegumento, tórax, abdômen, asas e todo o adulto de machos e fêmeas. Dentre os tratamentos, CL5 na primeira geração e CL10 na segunda geração foram aqueles com limiares mais baixos em relação ao peso do tórax e abdômen, considerando as proporções do corpo menores que as do sexo feminino. O peso da fêmea na idade adulta foi reduzido em 10% em relação aos machos e, apenas na primeira geração. Os machos têm tamanho corporal maior e plasticidade fenotípica mais pronunciada do que as fêmeas. Este estudo demonstra o primeiro estudo avaliando a plasticidade fenotípica de adultos de A. gemmatalis.

ABSTRACT

Introducción. El síndrome de Usher es una alteración genética caracterizada por la asociación de retinitis pigmentaria y sordera. Sin embargo, hay casos con familias en las cuales, a pesar de presentarse dicha asociación, no se puede diagnosticar un síndrome de Usher ni ninguno otro. Objetivo. Reevaluar fenotípicamente a 103 familias con diagnóstico previo de posible síndrome de Usher o retinitis pigmentaria asociada con sordera. Materiales y métodos. Se revisaron las historias clínicas de 103 familias con un posible diagnóstico clínico de síndrome de Usher o retinitis pigmentaria asociada con sordera. Se seleccionaron las familias cuyo diagnóstico clínico no correspondía a un síndrome de Usher típico. Los afectados fueron valorados oftalmológica y audiológicamente. Se analizaron variables demográficas y clínicas. Resultados. Se reevaluaron 14 familias cuyo diagnóstico clínico no correspondía al de síndrome de Usher. De las familias con diagnóstico inicial de síndrome de Usher típico, el 13,6 % recibieron uno posterior de "retinitis pigmentaria asociada con sordera" de "otro síntoma ocular asociado con hipoacusia',' o en forma aislada en una misma familia, de "retinitis pigmentaria" o "hipoacusia'.' Conclusiones. Es fundamental el estudio familiar en los casos en que la clínica no concuerda con el diagnóstico de síndrome de Usher típico. En los pacientes con retinitis pigmentaria asociada con sordera, el diagnóstico clínico acertado permite enfocar los análisis moleculares y, así, establecer un diagnóstico diferencial. Es necesario elaborar guías de nomenclatura en los casos con estos hallazgos atípicos para orientar a médicos e investigadores en cuanto a su correcto manejo.


Introduction: There are several syndromes that associate retinitis pigmentosa with deafness or hearing loss. The most frequent is Usher syndrome, a genetic disorder of autosomal recessive inheritance, which, in some cases, is accompanied by vestibular dysfunction. However, there are cases of families that despite having retinitis pigmentosa associated with deafness, cannot be classified as Usher or other syndromes due to additional findings. Objective: To reassess the phenotypes of 103 families previously diagnosed as possible Usher syndrome and/or retinitis pigmentosa associated with deafness. Materials and methods: We conducted a descriptive and retrospective study by reviewing the medical records of 103 families with a probable clinical diagnosis of Usher syndrome and/or retinitis pigmentosa associated with deafness. Families whose clinical diagnosis did not correspond to the typical Usher syndrome were selected and evaluated ophthalmologically and audiologically. Demographic and clinical variables were analyzed. Results: We selected and then reevaluated 14 families and 55 individuals as they did not correspond to a clinical diagnosis of Usher syndrome; 13.6% of the families initially considered to have typical Usher syndrome were later diagnosed with retinitis pigmentosa associated with deafness, another ocular symptom associated with hearing loss, retinitis pigmentosa, or isolated hearing loss in the same family. Conclusions: Family studies are essential in cases where the symptoms do not match the typical Usher' syndrome. In the cases of retinitis pigmentosa associated with deafness, a correct clinical diagnosis allows for focusing on the molecular analyses to establish a differential diagnosis. The need for nomenclature guidelines on these atypical findings is relevant to aid physicians and researchers in the best approach to these cases.

ABSTRACT

Abstract Introduction: psoriasis is a systemic, inflammatory, and chronic disease with a global prevalence between 0.6-6.5 %. It is related to multiple comorbidities and generates a significant decrease in quality of life. Objective: to characterize sociodemographic, clinical, pharmacological, and quality of life variables in a population of patients with moderate-severe psoriasis. Methods: descriptive observational study the patients with a diagnosis of severe-moderate psoriasis treated in the Clínica Integral de Psoriasis-CLIPSO between May 2018 - June 2020. A collection format was designed for defined variables and a univariate analysis was performed. Results: 948 patients were identified with a median age of 50 years (IQR: 38-60) of which 51.0 % were women. 23.6 % were incidents with a median treatment time of 114 days (IQR: 98-127) and 73.9 % were prevalent with a median treatment time of 228 days (IQR: 160-371). The type of therapy used was mainly non-biological systemic and 90.9 % of the patients were adherent to the treatment. The clinical variables were similar for both groups and the most common phenotype was psoriasis vulgaris (57.1 %). The health-related quality of life in both groups was greater than 60 points and the affected dimensions were physical and psychological health. 27.3 % of the patients had comorbidities associated with cardiovascular risk and 44.7 % were overweight. Conclusion: knowing the sociodemographic, clinical, pharmacological, and quality of life characteristics of patients with moderate-severe psoriasis allows the identification of risk factors and comprehensive management of the disease.

ABSTRACT

Abstract Introduction: Inflammatory bowel disease (IBD) is an immune-mediated disease whose incidence in Latin America has increased in recent years. Aim: To analyze the demographic and clinical characteristics of patients with IBD treated in a university hospital and present the epidemiological data compared to other centers in Colombia. Patients and methods: Descriptive study of patients with IBD (1996-2019) at the Hospital Universitario Fundación Santa Fe de Bogotá. Analysis of data from centers in Medellín, Cali, Bogotá, and Cartagena. Results: Of 386 patients, 277 presented with ulcerative colitis (UC), 102 with Crohn's disease (CD), and seven with unclassifiable colitis. IBD was more frequent in women (53 %). Mortality was less than 1 %. The involvement of UC was mainly pancolitis (42.6 %). The greater the extent of the disease, the higher the hospitalization and surgery rates (OR 3.70, P < 0.01). Thirteen percent of patients with UC received biologics. Compromise due to CD was mainly ileocolonic (43.6 %) and ileal (43.6 %). The predominant clinical pattern of CD was structuring (50%). Forty-five percent received biologicals and 56 % surgery. Primary sclerosing cholangitis (PSC) was found in 4 % of patients (n = 15). Two patients with PSC developed colorectal cancer (OR 4.18; p 0.008), while 13 patients with UC developed colon cancer and seven dysplastic changes. Three patients with CD developed colon cancer. Conclusions: The results were compared to other reference centers. We found similar trends in the clinical behavior and treatment of IBD, with higher hospitalization and surgery rates in our cases.


Resumen Introducción: la enfermedad inflamatoria intestinal (EII) es una enfermedad inmunomediada, cuya incidencia en Latinoamérica ha aumentado en los últimos años. Objetivo: analizar las características demográficas y clínicas de los pacientes con EII tratados en un hospital universitario y presentar los datos epidemiológicos con respecto a otros centros en Colombia. Pacientes y métodos: estudio descriptivo de pacientes con EII (1996-2019) en el Hospital Universitario Fundación Santa Fe de Bogotá. Análisis de datos de centros de Medellín, Cali, Bogotá y Cartagena. Resultados: de 386 pacientes, 277 presentaron colitis ulcerativa (CU), 102 enfermedad de Crohn (EC) y 7 colitis no clasificable. La EII fue más frecuente en mujeres (53 %). La mortalidad fue menor de 1 %. El compromiso de la CU fue principalmente la pancolitis (42,6 %). Entre mayor la extensión de la enfermedad, más alta fue la tasa de hospitalización y cirugías (OR 3,70; p < 0,01). El 13 % de los pacientes con CU recibió biológicos. El compromiso por la EC fue principalmente ileocolónico (43,6 %) e ileal (43,6 %). El patrón clínico predominante de la EC fue estenosante (50%). El 45 % recibió biológicos y 56% cirugía. La colangitis esclerosante primaria (CEP) se encontró en 4 % de los pacientes (n = 15). Dos pacientes con CEP desarrollaron cáncer colorrectal (OR 4,18; p 0,008), mientras que 13 pacientes con CU desarrollaron cáncer de colon y 7 cambios displásicos. 3 pacientes con EC desarrollaron cáncer de colon. Conclusiones: se compararon los resultados en relación con otros centros de referencia. Encontramos tendencias similares en el comportamiento clínico y en el tratamiento de la EII, con mayores tazas de hospitalizaciones y cirugías en nuestros casos.

ABSTRACT

Resumen Los desórdenes del Neurodesarrollo son en conjunto los diagnósticos más frecuentes en la práctica clínica en Neurología Infantil. De los años 70', se desarrolló una terminología usada para deno minar estos desordenes, con el objetivo de obtener mejor atención en servicios médicos y educativos para los afectados. A lo largo de los años, las clasificaciones han cambiado, pero el proceso fundamental del diagnóstico sigue siendo el mismo. Existe actualmente un movimiento para cambiar y establecer una nueva clasificación, basada en los déficits biológicos asociados con el fenotípico clínico. Esta nueva aproximación diagnóstica tiene como objetivo entre tantos otros, el diseño de intervenciones específicas que prometerían un mayor potencial curativo, a diferencia de las actuales opciones de tratamiento, que se basan en el manejo de síntomas. Impor tantes progresos se han hecho ya en este campo. Por ejemplo, algunos fenotipos conductuales en condiciones genéticas ampliamente conocidas como el Síndrome de Down, síndrome de X Frágil, neurofibromatosis, esclerosis tuberosa entre otros, han permitido proponer correlaciones biológicas con fenotipos comunes en pacientes con autismo, trastornos por déficit de atención, entre otros. Adicionalmente, el extenso estudio que actualmente se lleva a cabo sobre las denominadas enfermedades raras, que se asocian hasta en un 80% con trastornos del neurodesarrollo, ha abierto la posibilidad para muchas más correlaciones biológicas-comportamentales. En el futuro, será posible esperar oportunidades para la identificación de déficits biológicos moleculares, asociados con fenotipos clínicos cognitivos-conductuales y que, a partir de ellos se puedan diseñar intervenciones individuales a los problemas que hoy conocemos globalmente como los desórdenes del neurodesarrollo.


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

ABSTRACT

RESUMO Introdução: A reversão precoce da hipoperfusão tecidual induzida é essencial para a sobrevida no choque séptico. No entanto, falta consenso sobre a melhor estratégia de ressuscitação inicial, uma vez que intervenções destinadas a toda a população com choque séptico podem produzir administração desnecessária de líquidos. Este artigo relata a justificativa, o delineamento e o plano de análise do estudo ANDROMEDA-2, que visa determinar se uma estratégia guiada por perfusão periférica, que consiste na ressuscitação guiada pelo tempo de enchimento capilar com base em fenótipos clínicos e hemodinâmicos, está associada a uma diminuição no desfecho composto de mortalidade, tempo até a interrupção ao suporte de órgãos e tempo de internação em comparação com o atendimento padrão em pacientes com choque séptico precoce (< 4 horas do diagnóstico). Metódos: O estudo ANDROMEDA-2 é um ensaio clínico randomizado controlado multinacional e multicêntrico. No grupo de intervenção, o tempo de enchimento capilar será medido a cada hora, durante 6 horas. Se estiver anormal, os pacientes serão alocados em um algoritmo, começando com a avaliação da pressão de pulso. Pacientes com pressão de pulso inferior a 40mmHg serão testados quanto à capacidade de resposta a líquidos e receberão líquidos de acordo. Em pacientes com pressão de pulso > 40mmHg, norepinefrina será titulada para manter a pressão arterial diastólica > 50mmHg. Os pacientes que não normalizarem o tempo de enchimento capilar após as etapas anteriores serão submetidos à ecocardiografia de cuidados intensivos para avaliação da disfunção cardíaca e posterior manejo. Por fim, serão realizados testes com vasopressores e inodilatadores para otimizar ainda mais a perfusão. Um tamanho de amostra de 1.500 pacientes fornecerá 88% de poder para demonstrar a superioridade da estratégia direcionada ao tempo de enchimento capilar. Conclusão: Se for demonstrado que o direcionamento ao tempo de enchimento capilar é uma estratégia melhor, os processos de atendimento na ressuscitação do choque séptico podem ser otimizados com ferramentas usadas à beira do leito.


ABSTRACT Background: Early reversion of sepsis-induced tissue hypoperfusion is essential for survival in septic shock. However, consensus regarding the best initial resuscitation strategy is lacking given that interventions designed for the entire population with septic shock might produce unnecessary fluid administration. This article reports the rationale, study design and analysis plan of the ANDROMEDA-2 study, which aims to determine whether a peripheral perfusion-guided strategy consisting of capillary refill time-targeted resuscitation based on clinical and hemodynamic phenotypes is associated with a decrease in a composite outcome of mortality, time to organ support cessation, and hospital length of stay compared to standard care in patients with early (< 4 hours of diagnosis) septic shock. Methods: The ANDROMEDA-2 study is a multicenter, multinational randomized controlled trial. In the intervention group, capillary refill time will be measured hourly for 6 hours. If abnormal, patients will enter an algorithm starting with pulse pressure assessment. Patients with pulse pressure less than 40mmHg will be tested for fluid responsiveness and receive fluids accordingly. In patients with pulse pressure > 40mmHg, norepinephrine will be titrated to maintain diastolic arterial pressure > 50mmHg. Patients who fail to normalize capillary refill time after the previous steps will be subjected to critical care echocardiography for cardiac dysfunction evaluation and subsequent management. Finally, vasopressor and inodilator tests will be performed to further optimize perfusion. A sample size of 1,500 patients will provide 88% power to demonstrate superiority of the capillary refill time-targeted strategy. Conclusions: If hemodynamic phenotype-based, capillary refill time-targeted resuscitation demonstrates to be a superior strategy, care processes in septic shock resuscitation can be optimized with bedside tools.

ABSTRACT

ABSTRACT Objective: To assess the prevalence of the eosinophilic and allergic phenotypes of severe asthma in Brazil, as well as to investigate the clinical characteristics of severe asthma patients in the country. Methods: This was a cross-sectional study of adult patients diagnosed with severe asthma and managed at specialized centers in Brazil. The study was conducted in 2019. Results: A total of 385 patients were included in the study. Of those, 154 had a blood eosinophil count > 300 cells/mm3 and 231 had a blood eosinophil count of ≤ 300 cells/mm3. The median age was 54.0 years, and most of the patients were female, with a BMI of 29.0 kg/m2 and a history of allergy (81.6%). The prevalence of patients with a blood eosinophil count > 300 cells/mm3 was 40.0% (95% CI: 35.1-44.9), and that of those with a blood eosinophil count > 300 cells/mm3 and a history of allergy was 31.9% (95% CI: 27.3-36.6). Age and BMI showed positive associations with a blood eosinophil count > 300 cells/mm3 (OR = 0.97, p < 0.0001; and OR = 0.96, p = 0.0233, respectively), whereas the time elapsed since the onset of asthma symptoms showed an increased association with a blood eosinophil count > 300 cells/mm3 (OR = 1.02, p = 0.0011). Conclusions: This study allowed us to characterize the population of severe asthma patients in Brazil, showing the prevalence of the eosinophilic phenotype (in 40% of the sample). Our results reveal the relevance of the eosinophilic phenotype of severe asthma at a national level, contributing to increased effectiveness in managing the disease and implementing public health strategies.

ABSTRACT

ObjectiveTo observe the effect of Liuwei Dihuangtang (LWDHT) on depression-like behaviors of rats with diabetes mellitus and depression (DD) and explore its mechanism. MethodThe diabetes mellitus (DM) model was induced by the high-fat diet and tail vein injection of low-dose streptozotocin (STZ) in 50 male Sprague-Dawley rats of SPF grade. Then the DD model was induced by chronic unpredictable mild stress (CUMS) for 28 days in DM rats. Fifty DD rats were randomly divided into model group, fluoxetine group (10 mg·kg-1·d-1), and low-, medium-, and high-dose LWDHT groups (3.375, 6.75, 13.5 g·kg-1·d-1), with 10 rats in each group. Another 10 healthy rats were assigned into a control group and received normal saline by gavage. After four weeks of drug intervention, the forced swimming assay was carried out to assess the depression-like behaviors of rats. The expression levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-4 (IL-4), and interleukin-10 (IL-10) in the anterior cingulate cortex (ACC) were detected by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence was used to detect the expression of myelin basic protein (MBP) in ACC and the co-localization of ionized calcium-binding adapter molecule 1 (Iba1) with intracellular microtubule-associated protein 1 light chain 3 (LC3). The protein expression levels of MBP, myelin proteolipid protein (PLP), myelin oligodendrocyte glycoprotein (MOG), Beclin-1, LC3, p62, and microglia (MG) phenotypic protein-related inducible nitric oxide synthase (iNOS), and arginase 1 (Arg1) were detected by Western blot. ResultCompared with the control group, the model group showed shortened swimming time and prolonged immobility time (P<0.01). Compared with the model group, the medium- and high-dose LWDHT groups showed reduced immobility time (P<0.05, P<0.01). Compared with the control group, the model group showed decreased protein expression of MBP, PLP, and MOG in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated protein expression of MBP, PLP, and MOG (P<0.05, P<0.01). Compared with the control group, the model group showed decreased MBP fluorescence intensity in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed increased MBP fluorescence intensity in the ACC region (P<0.05, P<0.01). Compared with the control group, the model group showed increased expression of iNOS (P<0.01) and slightly increased Arg1 protein expression. Compared with the model group, the medium- and high-dose LWDHT groups and the fluoxetine group showed down-regulated iNOS expression and up-regulated Arg1 protein expression (P<0.05, P<0.01), but there was no significant difference between the fluoxetine group and the medium-,high-dose LWDHT groups. Compared with the control group, the model group showed increased expression levels of proinflammatory factors IL-1β and TNF-α in the ACC region (P<0.01) and slightly increased expression levels of anti-inflammatory factors IL-4 and IL-10. Compared with the model group, the fluoxetine group, and the medium- and high-dose LWDHT groups showed down-regulated expression of IL-1β and TNF-α (P<0.05, P<0.01) and up-regulated expression of IL-4 and IL-10 (P<0.05, P<0.01). Compared with the control group, the model group showed reduced expression levels of Beclin-1 and LC3Ⅱ (P<0.01) and increased expression level of p62 (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated Beclin-1 and LC3Ⅱ expression (P<0.01) and down-regulated p62 expression (P<0.01). Compared with the control group, the model group showed decreased LC3+Iba1+ cells in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed increased LC3+Iba1+ cells (P<0.05, P<0.01). ConclusionLWDHT can alleviate the depression-like behaviors in DD rats presumedly by promoting MG autophagy, regulating MG phenotypic changes, and increasing MG clearance of myelin sheath fragments. Meanwhile, MG phenotypic transformation also inhibits ACC inflammation in DD rats, improves the local microenvironment of oligodendrocyte proliferation and differentiation, and ultimately promotes the repair and remyelination of damaged myelin sheath.

ABSTRACT

Objective@#To investigate the difference in behavioral characteristics among different phenotypes of attention deficit hyperactivity disorder (ADHD) using amplitude of low-frequency fluctuation (ALFF), so as to provide insights into clinical differentiation of behavioral characteristics among different phenotypes of ADHD.@*Methods@#The children with ADHD admitted to The Affiliated Hospital of Hangzhou Normal University were enrolled and classified into the inattentive type (ADHD-I), hyperactive/impulsive type (ADHD-HI) and combined type (ADHD-C). The reaction time (RT) was measured using integrated visual and auditory continuous performance test, and the mean (RT-mean) and standard deviation of RT (RT-SD) were estimated. In addition, the ALFF was calculated at 0.010 to 0.027, 0.027 to 0.073, 0.073 to 0.167 Hz, and the difference of ALFF was compared among children with different types of ADHD.@*Results@#A total of 107 children with ADHD were enrolled, including 95 boys and 12 girls, with a mean age of (8.89±1.93) years. There were 69 children with ADHD-I, 8 children with ADHD-HI and 30 children with ADHD-C. The RT-SD was significantly higher among children with ADHD-C than among children with ADHD-I [(126.003±51.619) ms vs. (97.720±45.302) ms; P=0.007]; however, there was no significant difference in RT-mean among children with various ADHD phenotypes (F=1.386, P=0.255). There was an interaction between frequency and ADHD phenotypes (F=2.754, P=0.032), and the ALFF was significantly higher among children with ADHD-C than among children with ADHD-I at 0.010 to 0.027 [(5 590.567±231.595) ms vs. (4 694.001±154.397) ms; P=0.002] and 0.073 to 0.167 Hz [(4 312.609±174.709) ms vs. (3 690.805±116.473) ms; P=0.005].@*Conclusions@#The ALFF varies in ADHD phenotypes, and there is a frequency-specific difference.

ABSTRACT

Objective:To detect gene mutations in patients with mild phenotypes of neurofibromatosis type 1 (NF1) .Methods:From June 2017 to June 2020, 5 probands with mild phenotypes of NF1 only involving the skin and their family members were collected from Department of Dermatology, Fengxian Institute of Dermatosis Prevention and Treatment in Shanghai. Pedigree investigation was performed to evaluate the clinical phenotypes of NF1. The second-generation targeted gene sequencing combined with Sanger sequencing was performed to detect and verify pathogenic mutations.Results:All the 5 probands presented with only skin lesions, including café-au-lait spots, freckles, neurofibromas, but no other systemic involvement. A total of 5 mutations were identified in different exons of the NF1 gene in the 5 families, including 1 large-fragment deletion mutation (hg38: chr17:31327199-31335928 del 8 730 bp) , 1 splicing mutation (C.7970+1G>T) , 1 insertion mutation (C.3011_3012insTATG, p.N1004fs*) , 1 deletion mutation (C.1754_1757delTAAC, p.T586Vfs*18) , and 1 nonsense mutation (c.C503G, p.S168X) , and the first 3 above mentioned mutations were previously unreported novel mutations.Conclusion:Five mutations were identified in the 5 families with mild phenotypes of NF1, including 3 novel mutations, which expand the mutational spectrum of NF1.

ABSTRACT

Objective:To evaluate the effect of apneic oxygen insufflation (AOI) on phenotypic transformation of alveolar macrophage (AM) in the non-ventilated lung during one-lung ventilation (OLV).Methods:A total of 60 patients of either sex, aged 40-64 yr, weighing 45-85 kg, undergoing elective thoracoscopic lobectomy, were recruited and divided into 2 groups using a computer-generated table of random numbers: test group and control group, with 30 cases in each group.At the beginning of OLV, the non-ventilated lung received 3 L/min of AOI in test group and no AOI in control group.Radial artery blood samples were collected for blood gas analysis before operation, immediately after anesthesia induction, 30 min, 1 h and 2 h after the start of OLV, and oxygenation index (OI) was calculated.The resected normal lung tissues around the lung lobe were excised at 2 h after the start of OLV for microscopic examination of the pathological changes after HE staining, and the lung injury score was assessed.Bronchoalveolar lavage fluid (BALF) was collected at 2 h after the start of OLV, AM was sorted by flow cytometry, and the apoptotic rate was calculated.The levels of intracellular Ca 2+ and reactive oxygen species (ROS, a marker of M1 AM phenotype) in cells were determined.The concentrations of M1 phenotype AM markers inducible nitric oxide synthase (iNOS), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) and of M2 phenotype AM markers arginase 1 (Arg-1) and interleukin 10 (IL-10) in BALF were measured by enzyme-linked immunosorbent assay. Results:Compared with control group, SpO 2, PaO 2 and OI were significantly increased, PaCO 2 and lung injury score were decreased, the survival rate of AM was increased, the apoptotic rate in the early and late stages was decreased, the concentrations of iNOS, IL-6 and TNF-α in BALF were decreased, and the concentrations of Arg-1 and IL-10 in BALF were increased, the level of ROS in AM was decreased, and the level of Ca 2+ in AM was increased in test group ( P<0.05). Conclusions:The mechanism by which implementing AOI in the non-ventilated lung reduces lung injury may be related to promotion of transformation of AM from M1 phenotype to M2 phenotype and inhibition of inflammatory responses during OLV in the patients undergoing thoracoscopic lobectomy.

ABSTRACT

Objective:To analyze the clinical characteristics, treatment and prognosis of mixed phenotypic acute leukemia (MPAL) in children, and to provide reference for clinical optimization of diagnosis and treatment and improve the remission rate.Methods:Based on the diagnostic criteria of the World Health Organization (WHO) in 2016, the bone marrow cell morphology, immune typing, cytogenetics, molecular biological characteristics, treatment regimen, and prognosis of 15 children with MPAL who were admitted to Children′s Hospital Affiliated to Soochow University from January 2012 to December 2020 were retrospectively analyzed.The count data were compared between groups using the χ2 test, the measurement data that conformed to the normal distribution were compared using the t test, and the measurement data that were not normally distributed were compared using the rank sum test.Survival was estimated using the Kaplan- Meier ( K- M) method and the Log- rank method was used for comparison. Results:A total of 15 children with MPAL were admitted to Children′s Hospital Affiliated to Soochow University in the past 8 years, including 8 males and 7 females, with a median age of 6.8 years.Nine patients expressed B lymphocyte and myeloid phenotype, 5 patients expressed T lymphocyte and myeloid phenotype, and 1 patient expressed B and T lymphocyte phenotype.Karyotype of 11 children was examined, and the results showed that there were 2 cases of normal karyotype, 2 complex karyotype, 6 pseudodiploid and 1 subdiploid.Fusion genes were detected in 5 children, including 3 AML- ETO positive, 1 BCR- ABL positive, and 1 MLL gene positive.Thirteen patients were in complete remission (CR) after chemotherapy, with a total CR rate of 86.6% and a 2-year over survival (OS) rate of (68.2±13.4)%.Among the 15 children, 14 received induction chemotherapy and 1 gave up treatment for personal reasons.There were 10 patients with the first choice of acute lymphoblastic leukemia (ALL) chemotherapy regimen and 1 patient receiving CR, with a total CR rate of 10%.There were 4 cases of acute myeloid leukemia (AML) with the preferred chemotherapy regimen and 3 cases with CR in the first course of treatment, and the total CR rate was 75%.One case without remission was relieved after changing ALL chemotherapy regimen.The 2-year OS rates of 8 patients with hematopoietic stem cell transplantation (HSCT) and 6 patients without HSCT were (70.0±18.2)% and (66.7±19.2)%, respectively, with no significant difference ( χ2=0.318, P=0.573). Conclusions:Children with MPAL is a rare malignant tumor, mainly characterized by the co-expression of lymphoid and myeloid antigens.Chemotherapy alone or HSCT can achieve a good prognosis in the short term, but the long-term efficacy remains to be further observed.

ABSTRACT

Cellular senescence is a biological process associated with the degeneration of cell structure and function, which contribute to age-related diseases. Atherosclerosis is a chronic inflammatory disease that can cause a variety of cardiovascular disorders. In this article, we review the effects of cellular senescence on the development of atherosclerosis through diverse physiopathological changes, focusing on the alterations in senescent organelles and the increased senescence-associated secretory phenotype (SASP), and exploring the relevant therapeutic strategies for atherosclerosis by clearing senescent cells and reducing SASP, to provide new insights for the treatment of atherosclerosis.

ABSTRACT

OBJECTIVE@#This study aims to investigate the association of metabolic phenotypes that are jointly determined by body mass index (BMI) or fat mass percentage and metabolic health status with the ten-year risk of cardiovascular disease (CVD) among Chinese adults.@*METHODS@#Data were obtained from a cross-sectional study. BMI and body fat mass percentage (FMP) combined with the metabolic status were used to define metabolic phenotypes. Multiple linear regression and logistic regression were used to examine the effects of metabolic phenotypes on CVD risk.@*RESULTS@#A total of 13,239 adults aged 34-75 years were included in this study. Compared with the metabolically healthy non-obese (MHNO) phenotype, the metabolically unhealthy non-obese (MUNO) and metabolically unhealthy obese (MUO) phenotypes defined by BMI showed a higher CVD risk [odds ratio, OR (95% confidence interval, CI): 2.34 (1.89-2.89), 3.45 (2.50-4.75), respectively], after adjusting for the covariates. The MUNO and MUO phenotypes defined by FMP showed a higher CVD risk [ OR (95% CI): 2.31 (1.85-2.88), 2.63 (1.98-3.48), respectively] than the MHNO phenotype. The metabolically healthy obese phenotype, regardless of being defined by BMI or FMP, showed no CVD risk compared with the MHNO phenotype.@*CONCLUSION@#General obesity without central obesity does not increase CVD risk in metabolically healthy individuals. FMP might be a more meaningful factor for the evaluation of the association of obesity with CVD risk. Obesity and metabolic status have a synergistic effect on CVD risk.

ABSTRACT

Objective@#To study the postoperative soft and hard tissue changes and aesthetic effect of immediate implantation and provisionalization (IIPP) combined with guided bone regeneration (GBR) for a single anterior maxillary tooth with a thin facial bone phenotype.@*Methods @# A total of 34 patients with thin facial bone (<1 mm) were categorized into two groups: a flapped GBR group and a flapless group. Tooth extraction and IIPP were conducted at the sites in both groups. Implant survival rates, dimensional changes in soft and hard tissues during the six- and twelve-month follow-ups, the pink esthetic score (PES) and patient satisfaction scores at the twelve-month follow-up were measured.@*Results @#The implant survival rates were 100% in both groups, and no complications occurred during the 12 months after surgery. The facial bone thickness remained over 2 mm on all measured sides, and the height of the facial bone crest remained at 1.39 mm at the 12-month follow-up in the flapped GBR group, while the facial bone thickness remained less than 2 mm on all measured sides, and the height of the facial bone crest remained at 1.03 mm at the 12-month follow-up in the flapless group. The absorption of facial bone at all measured sides in the flapped GBR group was greater than that in the flapless group (P<0.05). There was no significant difference between the two groups in the dimensional changes of labial soft tissues during the six- and twelve-month follow-ups (P>0.05). The mean PES scores were 10.29 ± 2.34 for the flap GBR group and 10.12±1.78 for the flapless group (P = 0.807). The mean patient satisfaction scores were 8.65 ± 1.27 in the flapped GBR group and 8.76 ± 1.25 in the flapless group, and the patients in both of the groups were satisfied with the esthetic outcomes (P = 0.787). @*Conclusion @#IIPP combined with GBR might be a prospective treatment strategy for a single anterior maxillary tooth with a thin facial bone phenotype, but the esthetic risks should never be ignored.

ABSTRACT

Primary ciliary dyskinesia (PCD) is a hereditary disease characterized by airway mucociliary clearance dysfunction. The estimated prevalence of PCD is 1꞉10 000 to 1꞉20 000. The main respiratory manifestations in children are cough, expectoration, chronic rhinitis, sinusitis, and chronic otitis media, while the most common symptoms in adults are chronic sinusitis, bronchiectasis, and infertility. About 50% of patients with certain PCD-related gene variants are combined with situs inversus, and the incidence of congenital heart disease is also high. The pathogenesis behind PCD is that gene variants cause structural or functional disorders of respiratory cilia and motile cilia of other organs, leading to a series of heterogeneous clinical manifestations, which makes it difficult to identify and diagnose PCD. Combining different disease screening tools and understanding the relationship between genotypes and phenotypes may facilitate early diagnosis and treatment for PCD.

ABSTRACT

Abstract High doses of antibiotics used in hospitals can affect the microbial composition of sewers, selecting resistant bacteria. In this sense, we evaluated the antibiotic resistance profile and the multiresistant phenotype of bacteria isolated in sewage from a tertiary hospital in the interior São Paulo state, Brazil. For bacteria isolation, 10 µL of sewage samples were sown in selective culture media and the isolates were identified using VITEK-2 automatized system. The antibiotic sensitivity test was performed by disk diffusion. High percentages of resistance were found for amoxicillin, ampicillin, ceftazidime, clindamycin, vancomycin and the multidrug-resistant phenotype (MDR) was attributed to 60.7% of the isolates. Our results show bacteria classified as critical/high priority by WHO List of Priority Pathogens (Enterococcus and Staphylococcus aureus resistant to vancomycin and Enterobacteriaceae resistant to carbapenems) in hospital sewage. Therefore, the implementation of disinfection technologies for hospital sewage would reduce the bacterial load in the sewage that will reach urban wastewater treatment plants, minimizing superficial water contamination and bacterial resistance spread in the environment.


Resumo Altas doses de antibióticos utilizados em hospitais podem afetar a composição microbiana dos esgotos, selecionando bactérias resistentes. Nesse sentido, avaliamos o perfil de resistência a antibióticos e o fenótipo multirresistente de bactérias isoladas em esgoto de um hospital terciário no interior do estado de São Paulo, Brasil. Para o isolamento de bactérias, foram semeados 10 µL das amostras de esgoto em meios de cultura seletivos e os isolados foram identificados usando o sistema automatizado VITEK-2. O teste de sensibilidade aos antibióticos foi realizado por disco-difusão em ágar. Elevadas porcentagens de resistência foram encontradas para amoxicilina, ampicilina, ceftazidima, clindamicina, vancomicina e o fenótipo multirresistente (MDR) foi atribuído a 60,7% dos isolados. Nossos resultados mostram bactérias classificadas como prioridade crítica/alta pela Lista de Patógenos Prioritários da OMS (Enterococcus e Staphylococcus aureus resistentes à vancomicina e Enterobacteriaceae resistentes aos carbapenêmicos) no esgoto hospitalar. Sendo assim, implementação de tecnologias de desinfecção do esgoto hospitalar reduziriam a carga bacteriana no esgoto que chegará às estações de tratamento de esgoto urbanas, minimizando a contaminação dos ecossistemas hídricos receptores e a disseminação da resistência bacteriana no ambiente.
