OBJECTIVE@#To investigate the efficacy and safety of matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of young patients with multiple myeloma (MM).@*METHODS@#The clinical data of 8 young patients (median age:46 years) with MM who underwent allo-HSCT from HLA-indentical sibling donors in the First Affiliated Hospital of Chongqing Medical University from June 2013 to September 2021 were collected, and their survival and prognosis were retrospectively analyzed.@*RESULTS@#All the patients were successfully transplanted, and 7 patients could be evaluated the efficacy after transplantation. The median follow-up time was 35.2 (2.5-84.70) months. The complete response (CR) rate was 2/8 before transplantation and 6/7 after transplantation. Acute GVHD developed in 2 cases and extensive chronic GVHD developed in 1 case. Within 100 days, 1 case died of non-recurrent events, and 1-year and 2-year disease-free survival were 6 and 5 cases, respectively. At the end of follow-up, all the 5 patients who survived for more than 2 years survived, and the longest disease-free survival time has reached 84 months.@*CONCLUSION@#With the development of new drugs, HLA-matched sibling donor allo-HSCT may be a curable treatment for young patients with MM.

OBJECTIVES@#To investigate the efficacy of different numbers of microhaplotype (MH) loci and the introduction of different reference samples on the identification of full sibling, half sibling and differentiation between full sibling and half sibling kinships, and to explore the effect of changing mutation rate on sibling testing.@*METHODS@#First, a family map involving three generations was established, and four full sibling identification models, five half sibling identification models and five models distinguishing full and half siblings were constructed for different reference samples introduced. Based on the results of the previous study, two sets of nonbinary SNP-MH containing 34 and 54 loci were selected. Based on the above MH loci, 100 000 pairs of full sibling vs. unrelated individuals, 100 000 pairs of half sibling vs. unrelated individuals and 100 000 pairs of full sibling vs. half sibling were simulated based on the corresponding sibling kinship testing models, and the efficacy of each sibling kinship testing model was analyzed by the likelihood ratio algorithm under different thresholds. The mutant rate of 54 MH loci was changed to analyze the effect of mutation rate on sibling identification.@*RESULTS@#In the same relationship testing model, the systematic efficacy of sibling testing was positively correlated with the number of MH loci detected. With the same number of MH loci, the efficacy of full sibling testing was better than that of uncle or grandfather when the reference sample introduced was a full sibling of A, but there was no significant difference in the identification efficacy of the four reference samples introduced for full sibling and half sibling differentiation testing. In addition, the mutation rate had a slight effect on the efficacy of sibling kinship testing.@*CONCLUSIONS@#Increasing the number of MH loci and introducing reference samples of known relatives can increase the efficacy of full sibling testing, half sibling testing, and differentiation between full and half sibling kinships. The level of mutation rate in sibling testing by likelihood ratio method has a slight but insignificant effect on the efficacy.

OBJECTIVES@#To compare the application value of the likelihood ratio (LR) method and identity by state (IBS) method in the identification involving half sibling relationships, and to provide a reference for the setting of relevant standards for identification of half sibling relationship.@*METHODS@#(1) Based on the same genetic marker combinations, the reliability of computer simulation method was verified by comparing the distributions of cumulated identity by state score (CIBS) and combined full sibling index in actual cases with the distributions in simulated cases. (2) In different numbers of three genetic marker combinations, the simulation of full sibling, half sibling and unrelated individual pairs, each 1 million pairs, was obtained; the CIBS, as well as the corresponding types of cumulative LR parameters, were calculated. (3) The application value of LR method was compared with that of IBS method, by comparing the best system efficiency provided by LR method and IBS method when genetic markers in different amounts and of different types and accuracy were applied to distinguish the above three relational individual pairs. (4) According to the existing simulation data, the minimum number of genetic markers required to distinguish half siblings from the other two relationships using different types of genetic markers was estimated by curve fitting.@*RESULTS@#(1) After the rank sum test, under the premise that the real relationship and the genetic marker combination tested were the same, there was no significant difference between the simulation method and the results obtained in the actual case. (2) In most cases, under the same conditions, the system effectiveness obtained by LR method was greater than that by IBS method. (3) According to the existing data, the number of genetic markers required for full-half siblings and half sibling identification could be obtained by curve fitting when the system effectiveness reached 0.95 or 0.99.@*CONCLUSIONS@#When distinguishing half sibling from full sibling pairs or unrelated pairs, it is recommended to give preference to the LR method, and estimate the required number of markers according to the identification types and the population data, to ensure the identification effect.

OBJECTIVES@#To establish an analytical method for half sibling testing involving common three relatives' participation.@*METHODS@#Based on the half sibling testing scenarios with the known biological mother, grandfather or uncle, and two unidentified controversial half siblings participating, two opposing hypotheses were set. Lineage reconstruction according to Mendel's law of heredity was carried out, and the calculation formula of the half sibling kinship index was derived. Verification of actual cases was carried out and the results were compared with duo half sibling testing.@*RESULTS@#In the scenarios of the known biological mother, grandfather and uncle participating in half sibling testing, the kinship calculation formulae of 54, 91 and 99 genotype combinations for kinship index calculation were deduced respectively. The actual cases showed higher kinship indexes in trio half sibling testing compared with duo half sibling testing.@*CONCLUSIONS@#It is beneficial to obtain more genetic information for family reconstruction and improvement of the strength of genetic evidence for half sibling testing by adding known relatives.

OBJECTIVES@#To study the detection efficiency of trio full sibling with another known full sibling reference added under different number of autosomal STR typing systems.@*METHODS@#Based on 43 detection systems consisting of 13 to 55 representative autosomal STR loci, 10 000 true families (full sibling group) and 10 000 false families (unrelated individual group) were randomly simulated. The full sibling index (FSI) was calculated based on the method of family reconstruction. The cumulative sibling relationship index (CFSI) of 0.000 1 and 10 000 were used as the evaluation thresholds, and the detection efficiency parameters were calculated and compared with the identification of the duo full sibling testing.@*RESULTS@#With the increasing number of STR loci, the error rate and inability of judgement rate gradually decreased; the sensitivity, specificity, correct rate of judgment and other parameters gradually increased, and the system efficiency gradually improved. Under the same detection system, trio full sibling testing showed higher sensitivity, specificity, system efficiency and lower inability of judgement rate compared with duo full sibling testing. When the system efficiency was higher than 0.85 and inability of judgement rate was less than 0.01%, at least 20 STRs should be detected for trio full sibling testing, which was less than 29 STRs required by duo full sibling testing.@*CONCLUSIONS@#The detection efficiency of trio full sibling testing is superior to that of duo full sibling testing with the same detection system, which is an effective identification scheme for laboratories with inadequate detection systems or for materials with limited conditions.

OBJECTIVES@#To estimate the system efficiency of uncle-nephew relationship identification by increasing STR markers and adding reference samples based on the test results of simulated data and real samples, so as to provide references for selecting the appropriate number of STRs and reference samples for uncle-nephew relationship identification.@*METHODS@#Five common models of uncle-nephew relationship identification were constructed by adding different reference samples. In each model, the likelihood ratio (LR) for 10 000 pairs of uncle-nephew relationships and 10 000 pairs of unrelated individuals were simulated by detecting 19, 39 or 55 STRs, and the system efficiency at different thresholds was simulated. The samples of the Han population in Zhejiang were collected, and 55 autosomal STRs were obtained by using SiFaSTRTM 23plex kit, Goldeneye® DNA ID 22NC kit and AGCU 21+1 PCR amplification kit. When 19, 39 and 55 STRs were detected, the LR of each model and system efficiency under different thresholds were calculated and compared with the simulation results.@*RESULTS@#Under the same detection system, the calculated results of simulated data and corresponding true samples were basically consistent. In the same model, there was a positive correlation between the system efficiency of uncle-nephew relationship identification and the number of STRs detected. Moreover, the system efficiency of introducing relatives was higher than identifying only two individuals. The order of preference for the introduction of relatives was the full sibling (or mother) of the uncle and the full sibling (or mother) of the nephew.@*CONCLUSIONS@#The system efficiency of uncle-nephew relationship identification could be improved by increasing the number of STRs and introducing known relatives, which would provide the basis for selecting the most appropriate detection system and reference individuals in actual cases.

Objective: To investigate whether haplotype hematopoietic stem cell transplantation (haplo-HSCT) is effective in the treatment of pre transplant minimal residual disease (Pre-MRD) positive acute B lymphoblastic leukemia (B-ALL) compared with HLA- matched sibling donor transplantation (MSDT) . Methods: A total of 998 patients with B-ALL in complete remission pre-HSCT who either received haplo-HSCT (n=788) or underwent MSDT (n=210) were retrospectively analyzed. The pre-transplantation leukemia burden was evaluated according to Pre-MRD determinedusing multiparameter flow cytometry (MFC) . Results: Of these patients, 997 (99.9% ) achieved sustained, full donor chimerism. The 100-day cumulative incidences of neutrophil engraftment, platelet engraftment, and grades Ⅱ-Ⅳ acute graft-versus-host disease (GVHD) were 99.9% (997/998) , 95.3% (951/998) , and 26.6% (95% CI 23.8% -29.4% ) , respectively. The 3-year cumulative incidence of total chronic GVHD was 49.1% (95% CI 45.7% -52.4% ) . The 3-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) of the 998 cases were 17.3% (95% CI 15.0% -19.7% ) and 13.8% (95% CI 11.6% -16.0% ) , respectively. The 3-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 69.1% (95% CI 66.1% -72.1% ) and 73.0% (95% CI 70.2% -75.8% ) , respectively. In the total patient group, cases with positive Pre-MRD (n=282) experienced significantly higher CIR than that of subjects with negative Pre-MRD [n=716, 31.6% (95% CI 25.8% -37.5% ) vs 14.3% (95% CI 11.4% -17.2% ) , P<0.001]. For patients in the positive Pre-MRD subgroup, cases treated with haplo-HSCT (n=219) had a lower 3-year CIR than that of cases who underwent MSDT [n=63, 27.2% (95% CI 21.0% -33.4% ) vs 47.0% (95% CI 33.8% -60.2% ) , P=0.002]. The total 998 cases were classified as five subgroups, including cases with negative Pre-MRD group (n=716) , cases with Pre-MRD<0.01% group (n=46) , cases with Pre-MRD 0.01% -<0.1% group (n=117) , cases with Pre-MRD 0.1% -<1% group (n=87) , and cases with Pre-MRD≥1% group (n=32) . For subjects in the Pre-MRD<0.01% group, haplo-HSCT (n=40) had a lower CIR than that of MSDT [n=6, 10.0% (95% CI 0.4% -19.6% ) vs 32.3% (95% CI 0% -69.9% ) , P=0.017]. For patients in the Pre-MRD 0.01% -<0.1% group, haplo-HSCT (n=81) also had a lower 3-year CIR than that of MSDT [n=36, 20.4% (95% CI 10.4% -30.4% ) vs 47.0% (95% CI 29.2% -64.8% ) , P=0.004]. In the other three subgroups, the 3-year CIR was comparable between patients who underwent haplo-HSCT and those received MSDT. A subgroup analysis of patients with Pre-MRD<0.1% (n=163) was performed, the results showed that cases received haplo-HSCT (n=121) experienced lower 3-year CIR [16.0% (95% CI 9.4% -22.7% ) vs 40.5% (95% CI 25.2% -55.8% ) , P<0.001], better 3-year LFS [78.2% (95% CI 70.6% -85.8% ) vs 47.6% (95% CI 32.2% -63.0% ) , P<0.001] and OS [80.5% (95% CI 73.1% -87.9% ) vs 54.6% (95% CI 39.2% -70.0% ) , P<0.001] than those of MSDT (n=42) , but comparable in 3-year NRM [5.8% (95% CI 1.6% -10.0% ) vs 11.9% (95% CI 2.0% -21.8% ) , P=0.188]. Multivariate analysis showed that haplo-HSCT was associated with lower CIR (HR=0.248, 95% CI 0.131-0.472, P<0.001) , and superior LFS (HR=0.275, 95% CI 0.157-0.483, P<0.001) and OS (HR=0.286, 95% CI 0.159-0.513, P<0.001) . Conclusion: Haplo HSCT has a survival advantage over MSDT in the treatment of B-ALL patients with pre MRD<0.1% .

Abstract Objective: to understand, by means of dramatic therapeutic play, the meaning, for the sibling, of visiting the child hospitalized in intensive care. Method: a qualitative research, phenomenological modality, which used the dramatic therapeutic play to access the siblings' experiences. It was carried out in a Pediatric Intensive Care Unit in the countryside of the State of São Paulo, Brazil. Eleven siblings under ten years of age participated in the therapeutic play sessions, which were analyzed in the light of the Theory of Maturation. Results: the siblings, having a place to play, dramatized previously lived situations, from their daily life and from the visit to the hospitalized child. By living creatively, they revealed that playing is to integrate the experiences of the "I", favoring the continuity of being in the face of the situation lived. Conclusions and implications for practice: the Dramatic Therapeutic Play understood in the light of a theoretical framework allowed the sibling to mean the visit as an experience of integration of the "I", revealing emotions, desires and preferences of daily life. In this sense, the care for the brother of the hospitalized child is defined by the offer of free play, so that he demonstrates the feeling of continuing to be in his interactions with the world, in which the hospital context has become part of reality.

Este estudo buscou investigar as perspectivas de adolescentes sobre a prática de cuidado dos irmãos. A amostra foi composta por seis adolescentes de ambos os sexos, com idades entre 11 e 19 anos. Os dados foram coletados por meio de entrevistas semiestruturadas e as informações foram submetidas à análise de conteúdo. Ressalta-se a importância das atividades desempenhadas pelos adolescentes no contexto familiar para o sustento financeiro da família. A percepção do cuidador sobre o cuidado dispensado aos irmãos abarcou aspectos positivos e negativos, sendo também considerada uma prática normal e rotineira. Dentre os pontos positivos, constatou-se transmitir algo de bom aos irmãos, os desafios e facilidades na realização de atividades de cuidado com os irmãos menores. A prática do cuidado pode contribuir para o sentimento de importância no contexto familiar, como também ser percebida como uma falha das mães no cumprimento de suas responsabilidades. As percepções negativas referiram-se à limitação dos tempos de lazer, à rotina estressante e à mediação de brigas entre os irmãos menores. Evidencia-se a importância de analisar o que essa prática representa para os adolescentes cuidadores, já que esta pode estar associada a sentimentos de desconforto, influenciar o bem-estar, bem como limitar a realização de atividades de lazer.(AU)

This study sought to investigate the perspectives of adolescents about their sibling caretaking. The sample consisted of six adolescents of both sexes, aged between 11 and 19 years old. The data were collected through semi-structured interviews and were submitted to content analysis. The importance of the activities performed by adolescents in the family context for the financial support of the family is emphasized. The caregiver's perception of the care given to siblings contained positive and negative aspects, and was also considered to be routine practice. Among the positives factors, it was found to transmit something good to the siblings, the challenges and facilities in carrying out care activities to younger siblings. The sibling caretaking practice can contribute to the feeling of importance in the family context, as well as being perceived as a failure of mothers in carrying out their responsibilities. Negative perceptions referred to the limitation of leisure time, the stressful routine and the mediation of fights between younger siblings. The importance of analyzing what this practice represents for young caregivers is evident, as it can be associated with uncomfortable feelings, influence well-being, as well as limit the performance of leisure activities.(AU)

Resumen La infección por parvovirus humano B19 es una de las complicaciones comunes en pacientes diagnosticados de enfermedad de células falciformes (ECF). Se caracteriza por una anemia grave con reticulocitopenia, pudiendo estar acompañada de otras manifestaciones clínicas. En ocasiones, la infección puede ocurrir de modo simultáneo en contactos intrafamiliares de un paciente también con ECF. Es fundamental el reconocimiento temprano de esta complicación y el diagnóstico diferencial con otras patologías para su correcto manejo y tratamiento. Presentamos el caso de dos hermanos con ECF e infección por parvovirus humano B19.

Abstract Human parvovirus B19 infection is one of the common complications of patients diagnosed with Sickle cell disease (SCD). Parvovirus infections are characterized by a severe anemia with reticulocytopenia, sometimes presenting with other clinical manifestations. The infection can occur simultaneously in patient's cohabitants also diagnosed with SCD. Early recognition and differential diagnosis are essential for a proper disease management and treatment. We present two siblings with SCD and human parvovirus B19 infection.

ABSTRACT Objective: To evaluate if the variables child's sex, age, presence of siblings, parents working remotely, and external space affect the level of physical activity (PA) of Brazilian children during social distancing imposed by the COVID-19 pandemic. Methods: An online questionnaire was applied by the LimeSurvey software from March to April 2020. Children were divided into four age groups, and the questionnaire comprised questions on family and household characteristics, domestic and children's routines in the period of Brazilian social distancing. Based on the answers concerning children's activities, the following variable was created: percentage of physical activity (%PA) in one-day period. Analysis of variance and regression analysis were performed to investigate the effect of demographic and parental activities on %PA. Results: The %PA decreases with increasing age, but increases with the availability of external space at home. No significant or interaction effects were observed for other variables. Age and external space at home are predictors of %PA. Conclusions: Household and personal characteristics of Brazilian children influence the level of physical activity performed by them during social distancing. Preventive measures can be adopted in the face of another similar period.

RESUMO Objetivo: Investigar se as variáveis sexo da criança, idade, presença de irmãos, pais trabalhando de maneira remota e espaço externo afetam o nível de atividade física das crianças brasileiras durante o distanciamento social por COVID-19. Métodos: Aplicou-se questionário online pelo LimeSurvey, em março e abril de 2020, sobre características familiares e habitacionais, rotinas domésticas e infantis no período de distanciamento social brasileiro, sendo as crianças divididas em quatro grupos etários. Com base nas atividades infantis realizadas, criou-se a porcentagem de atividade física (%AF) em relação ao período de um dia e foi desenvolvida análise de variância para investigar o efeito das variáveis na %AF, além de análise de regressão. Resultados: A %AF diminui conforme o aumento da idade, mas aumenta com a disponibilidade de espaço externo no domicílio. Não houve efeito significativo para as demais variáveis, tampouco efeito de interação. A idade e o espaço externo ao domicílio são preditores da %AF.

OBJECTIVE@#To provide a basis for genetic counseling and clinical precision therapy by exploring the genetic etiology of a child with recurrent hypoglycemia convulsion accompanied by language retardation.@*METHODS@#Peripheral blood samples were obtained from the proband, his sister and his parents. Whole genomic DNA was extracted and analyzed by the whole exon gene sequencing and confirmed by Sanger sequencing.@*RESULTS@#The proband and his sister were found to carry compound heterozygous variants c.731T>A (p.M244L) and c.928G>A (p.G244S) of the GYS2 gene, which had not been reported in the past, the c.731T>A (p.M244L) site was derived from the maternal heterozygous mutation, while c.928G>A (p.G244S) site from the father heterozygous mutation.@*CONCLUSION@#The compound heterozygous variants c.731T>A (p.M244L) and c.928G>A (p.G244S) of the GYS2 gene were the genetic cause of glycogen storage syndrome type 0 in children, providing basis for family genetic counseling. When the patient had Hypoglycemia often accompanied with convulsions, which was easy to be misdiagnosed as seizures, and the antiepileptic treatment was ineffective. After genetic diagnosis, the seizure can be controlled by improving diet to maintain blood glucose stability.

OBJECTIVE@#To report on a family which has two siblings with SCN2A mutation caused by germline mosaicism suffering from autism spectrum disorder/development delay (ASD/DD).@*METHODS@#Clinical data was collected for the proband and his parents. Next generation sequencing (NGS) was carried out on the proband and his parents. Suspected mutations were verified by Sanger sequencing of the proband, his parents and brother. To detect whether there is a low proportion of somatic mosaicism in the parents, a droplet digital PCR was conducted. The result of ddPCR showed that the father was germline mosaicism (0.233%).@*RESULTS@#NGS has identified a de novo splicing mutation of the SCN2A gene, c.605+1G>A, in the proband and his brother. Combined with its clinical phenotype and inheritance pattern, SCN2A was judged to be the pathogenic gene. Above findings strongly suggested parental germline mosaicism.@*CONCLUSION@#ASD/DD in siblings with SCN2A mutations caused by germline mosaicism. Paternal mosaicism should be considered as one of the important inheritance patterns for counseling parents with a child carrying SCN2A mutation. The ddPCR can help to reveal very low proportion of germline mosaicism.

OBJECTIVE@#Two brothes with Seckel's syndrome 1(SCKL1) were reported and a literature review was carried to provide clinical and genetic information of this rare disease.@*METHODS@#Clinical data of the two children were collected, and the peripheral blood was extracted for whole exome sequencing. Literature of the disease were reviewed.@*RESULTS@#The two patients were 11 years and 9.5 years old when examined for short stature. They presented with intrauterine growth retardation, intellectual disability, microcephaly, birdhead-like face and coffee au lait spots. The bone age was more than 2 years behind the chronical age and the growth hormone levels were normal. Whole exome sequencing revealed novel compound heterozygous variants c.1A>G (p.M1?) and c.4853-18A>G of ART gene in both children.@*CONCLUSION@#Children with prenatal onset short stature, developmental delay, microcephaly and special facial featuresshould be considered for the possibility of Seckel's syndrome, whole exome sequencing could help to confirm the clinical diagnosis.

ABSTRACT Becoming mother of a second child, as a parental transition phenomenon, poses a challenge to reflection in Nursing. This theoretical study intends to present a reflection on the being who being-in-the-world becomes mother of a second child. It is based on Heideggerian phenomenology and nursing thought. The text is organized around two axes: Heidegger's conceptual contributions and nursing thought. The Heideggerian ontological dimension, aligned with the humanistic presuppositions of Nursing, contributes to unfold the meanings of life experiences and broaden possibilities of caring of the being who being-in-the-world… becomes mother of a second child. Concomitantly, the access to the experience of women who being-in-the-world become mother of a second child enables widening comprehension of this phenomenon, which will certainly impact nurses' being-present in their daily care.

RESUMEN Convertirse en madre de un segundo hijo, en tanto que fenómeno de transición a la parentalidad, se configura como un desafío a la reflexión de Enfermería. Este estudio teórico pretende presentar una reflexión sobre el ser que, siendo-en-el-mundo, se convierte en madre de un segundo hijo a la luz de la fenomenología heideggeriana y del pensamiento enfermero. El texto se organizó en torno a dos ejes: las contribuciones conceptuales de Heidegger y el pensamiento enfermero. Se identifica que la dimensión ontológica heideggeriana, junto con los presupuestos humanísticos de la Enfermería, contribuyen a desvelar los sentidos de lo vivido y a ampliar las posibilidades de cuidar al ser que, siendo-en-el-mundo… se convierte en madre de un segundo hijo. Concomitantemente, el acceso a la experiencia de la mujer que, siendo-en-el-mundo, se convierte en madre de un segundo hijo, permite abrir el horizonte de comprensión del fenómeno, lo que sin duda repercutirá en el modo de ser-presente de los enfermeros en sus cuidados diarios.

RESUMO Tornar-se mãe de um segundo filho, enquanto fenómeno de transição na parentalidade, configura-se como um desafio à reflexão em Enfermagem. Pretende-se neste estudo teórico apresentar uma reflexão sobre o ser que sendo-no-mundo se torna mãe de um segundo filho à luz da fenomenologia heideggeriana e do pensamento de enfermagem. O texto foi organizado em torno de dois eixos: os contributos conceptuais de Heidegger e o pensamento de enfermagem. Identifica-se que a dimensão ontológica heideggeriana, alinhada com os pressupostos humanísticos da Enfermagem, contribui para desvelar os sentidos do vivido e ampliar as possibilidades de cuidar do ser que sendo-no-mundo… se torna mãe de um segundo filho. Concomitantemente, o acesso à experiência da mulher que sendo-no-mundo se torna mãe de um segundo filho permite abrir o horizonte de compreensão face ao fenómeno, o que certamente terá impacto no modo de ser-presente do enfermeiro no quotidiano de cuidados.
