Effects of subclinical hypothyroidism during pregnancy treated with LT 4 on the growth and neuropsychology of offspring aged 0-36 months: A cohort study / 中华内分泌代谢杂志

Objective:To evaluate the effects of subclinical hypothyroidism during pregnancy treated with LT 4 on the growth and neuropsychology of offspring aged 0-36 months. Methods:A maternal-infant cohort was established in healthy singleton pregnant women aged 20-45 years without history of thyroid disease. Women developing subclinical hypothyroidism during pregnancy were treated with LT4. The weight, length, and head circumference of the offspring were recorded between 0 to 36 months after birth. Meanwhile, infant nutrition and family support were investigated. The Neuropsychological Development Questionnaire of 0-6 year old children was used to evaluate the neurodevelopment of offspring.Results:A total of 186 mother-infant pairs were included. All subjects were divided into the euthyroidism(ETH) group( n=136) and subclinical hypothyroidism(SHT) group( n=50) according to maternal thyroid function during pregnancy. The Z-scores(adjusted by months of age and gender) of weight, length, weight/length at birth, weight/length at 1 month, head circumference at 6 months, length at 8 months, weight/length at 24 months of SHT group were lower than those of the ETH group( P<0.05). Furthermore, the language competence of the SHT offspring at 12 months of age was also lower than that of the ETH group( P<0.05). Maternal subclinical hypothyroidism treated with LT 4 did not significantly affect preterm delivery, low birth weight, and developmental quotient <85, but reduced the risk of macrosomia(AOR 0.206, 95% CI 0.046-0.929, P=0.040). Conclusion:Although women with subclinical hypothyroidism received LT 4 treatment during pregnancy, the offspring still may suffer adverse effects on their growth and neural development.

Longitud cráneo raquis: predictora del crecimiento fetal y de la condición trófica del recién nacido / Cranio-spinal length: predictor of fetal growth and the trophic condition of the newborn

RESUMEN Fundamento: la edad y el crecimiento fetal se determinan mediante la longitud céfalo-caudal o cráneo raquis entre las semanas cinco y 10 de la gestación y después se recurre a una combinación de medidas de otras variables biométricas. Objetivo: identificar correlación de las variables biométricas y condición trófica al nacer con la longitud cráneo raquis del primer trimestre. Métodos: se realizó una investigación con diseño analítico longitudinal retrospectivo en la provincia Villa Clara, se recurrió al período comprendido entre enero de 2013 a octubre de 2018. La población estuvo conformada por 6 050 gestantes. La muestra se realizó a través de un muestreo no probabilístico intencional por criterios, constituida por 3 910 gestantes. Se obtuvieron datos de libros, registros de las consultas de genética de áreas de salud seleccionadas. En el análisis, se utilizaron el coeficiente de correlación lineal de Pearson, de Rho de Spearman y diagramas de dispersión. Resultados: existió correlación entre longitud cráneo raquis con las variables y con la condición trófica del recién nacido. Los gráficos que definieron la trayectoria de las variables biométricas desde el segundo trimestre hasta el parto mostraron compactación de los valores hasta la semana 25 y dispersión entre la 25 y la 30 con rasgos diferenciales en las mismas. Conclusiones: la correlación encontrada de la longitud cráneo raquis con las variables biométricas y con la condición trófica del recién nacido demuestra la utilidad del empleo de esta variable en la evolución del embarazo tanto por el obstetra como por el médico general integral; en lo particular en gestantes en las que se sospeche alguna alteración del crecimiento. Los resultados obtenidos motivan a la profundización al subdividir la muestra en subgrupos como las afectadas de diabetes mellitus o hipertensión arterial u otra, porque no existe en la literatura información sobre la misma.

ABSTRACT Background: age and fetal growth are determined by head length or cranial-spinal length between weeks 5 and 10 of gestation and then a combination of measurements of other biometric variables is used. Objective: to identify the correlation of biometric variables and trophic condition at birth with the cranial-spinal length of the first trimester. Methods: an investigation with a retrospective longitudinal analytical design was carried out in Villa Clara province; it was appealed in the period from January 2013 to October 2018. The population consisted of 6050 pregnant women. The sample was made through an intentional non-probabilistic sampling by criteria, consisting of 3 910 pregnant women. Data were obtained from genetics consultation record books from selected health areas. In the analysis, Pearson's linear correlation coefficient, Spearman's Rho, and scatter diagrams were used. Results: there was a correlation between the cranial-spinal length with the variables and with the trophic condition of the newborn. The graphs that defined the trajectory of the biometric variables from the second trimester to delivery showed compaction of the values ​​up to week 25 and dispersion between week 25 and 30 with differential features in them. Conclusions: the correlation found of cranial-spinal length with biometric variables and with the trophic condition of the newborn demonstrates the usefulness of the use of this variable in the evolution of pregnancy by both the obstetrician and the comprehensive general practitioner; particularly in pregnant women in whom some growth alteration is suspected. The results obtained motivate further study by subdividing the sample into subgroups such as those affected by diabetes mellitus or arterial hypertension or another, particularly because there is no information on it in the literature.

The Effect Of Postpartum Coping Skill Classes (PCSC) On Stress Level, Cortisol Levels, Maternal Self- Efficacy, And Baby’s Growth And Development In Semarang, Central Java

@#Postpartum stress incidence rate is quite high (26% - 85%). Several studies reveal that more than 50% of women experience stress and depression after giving birth and almost 80% of new mothers experience terrible sadness feelings after giving birth, often called postpartum stress. This study aims to determine the effect of postpartum coping skill classes (PCSC) on stress level, cortisol level, maternal self-efficacy (MSE), and baby's growth and development. This study employed an experimental design method with a randomized study pre-test post-test control group design. The study was conducted on 18 postpartum women who were given PCSC treatment which was integrated into postpartum classes and 17 women were given postpartum classes (PC) only. The study was conducted in 4 weeks. The data were analyzed statistically using a t-test method. Ethical clearance for the study was obtained. The results disclose that PCSC significantly decrease the PSS score (-2.66 ± 4.74, p = 0,029). Similarly, the cortisol level drops significantly (-38.53 ± 74.60, p = 0.031). In other respect, the MSE score between groups have significant mean difference (p = 0.013), but the weight gain and development of the baby between the two groups have no significant mean difference (p >0.05). The provision of coping skill classes through maternal classes for postpartum women was effective in decreasing stress levels, cortisol levels, and increasing MSE scores although it did not affect the baby's growth and development.

Fluctuaciones de la homeostasis del zinc relacionadas con estadios del crecimiento-desarrollo humano / Fluctuations of zinc homeostatics related to the human growth-development stages

Se conoce que el Factor de Crecimiento Insulino Dependiente I (IGF-I), disminuye su expresión en presencia de déficit plasmático de zinc. El objetivo de la presente revisión es relacionar fluctuaciones de la homeostasis del zinc con estadios del crecimiento-desarrollo humano. De la discusión de la data presentada se tiene que: el crecimiento‒desarrollo humano es un proceso con incidencias del calcio y del zinc, donde el déficit de zinc resulta un factor de alto riesgo para el nacimiento prematuro de infantes y de niños con baja talla; existen evidencias suficientes para inferir una asociación débil directa entre el incremento gradual de los niveles plasmáticos de zinc y calcio con el aumento de la edad durante la infancia y la adolescencia y de que la interacción de colaboración entre el calcio y el zinc en la osteogénesis, sufre una diferenciación de funciones en la osificación endocondral, y se transforma en una relación de competencia en la formación del esmalte dental; se manifiesta como tendencia un incremento del zinc plasmático con el aumento de la edad, con sesgos debidos al sobrepeso y la obesidad y a la fertilidad productiva de la mujer. Puede entonces considerarse finalmente que la homeóstasis del zinc plasmático, estabilizada en un intervalo de valores normales para un estadio dado, propicia el crecimiento‒desarrollo necesario y suficiente, siendo el envejecimiento un momento de involución en aquella tendencia de incremento de valores plasmáticos de zinc con la edad.

It is known that the Factor of Insulin Dependent Growth I (IGF-I), it diminishes their expression in presence of plasmatic deficit of zinc. The objective of the present revision is to relate fluctuations of the homeostasis of the zinc with stages of the human growth-development. Of the discussion of it dates it presented one has that: the human growth-development is a process with incidences of the calcium and of the zinc, where the deficit of zinc is a factor of high risk for the premature birth of infants and of children with drop carves; enough evidences exist to infer a direct weak association between the gradual increment of the plasmatic levels of zinc and calcium with the increase of the age during the childhood and the adolescence and that the interaction of collaboration between the calcium and the zinc in the osteogenesis, suffers a differentiation of functions in the enchondral ossification , and it becomes a competition relationship in the formation of the dental enamel ; it is manifested as tendency an increment of the plasmatic zinc with the increase of the age, with due biases to the overweight and the obesity and to the woman's productive fertility. Then it can be considered finally that the homeostasis of the plasmatic zinc, stabilized in an interval of normal values for a given stadium, favorable the necessary and enough growth-development being the aging an involution moment in that tendency of increment of plasmatic values of zinc with the age.

Avaliação radiográfica do desenvolvimento dental em portadores de diabetes mellitus 1 ­ enfoque clínico e pericial / Radiographic assessment of the dental development in patients with diabetes mellitus type 1 ­ clinical and forensic approach

Introdução: O diabetes mellitus do tipo 1 (DM1) é um distúrbio metabólico capaz de afetar o desenvolvimento do portador. O conhecimento deste tema permitirá ao Cirurgião-dentista planejar com maior segurança procedimentos clínicos que dependem da resposta biológica do paciente, e realizar perícias de estimativa de idade de forma mais precisa. Objetivo: Avaliar o desenvolvimento dental em portadores de DM1 correlacionando duas técnicas para estimativa de idade. Métodos: Foram analisadas 90 radiografias panorâmicas de indivíduos com idades entre 5-16 anos, distribuídas nos grupos caso (n=45) e controle (n=45). Foram avaliados os estágios de calcificação dos dentes 36 e 37 segundo Demirjian et al. (1973) e o irrompimento dental segundo Lewis e Garn (1960). Resultados: Para o dente 36, observou-se maior prevalência de indivíduos do grupo controle com dentes irrompidos no estágio H em relação ao grupo caso (75,6% e 71,1%, respectivamente). Para o dente 37, observou-se maior prevalência de indivíduos do grupo controle com dentes irrompidos no estágio G em relação ao grupo caso (40,0% e 35,6%, respectivamente). Diferença estatisticamente significante não foram observadas entre os grupos quando os métodos foram analisados independentemente (valores de p>0,05). Conclusão: Desenvolvimento dental similar foi observado entre os grupos caso e controle. Perícias forenses de estimativa de idade em pacientes DM1 devem priorizar métodos radiográficos que examinam os estágios de calcificação dental.

Introduction: Diabetes mellitus type 1 (DM1) is a metabolic disorder able to impact within development. The knowledge around this topic will allow the Dentist to plan safer clinical procedures that depend on the biological response of the patients, as well to performed age estimation expertises more accurately. Objective: To assess the dental development in DM1 patients correlating two techniques for age estimation. Methods: A sample of 90 panoramic radiographs of subjects aged between 5-16 years old, distributed in groups case (n=45) and control (n=45). Dental development was assessed considering the calcification stages of the teeth 36 and 37 according to Demirjian et al. (1973) and the dental eruption of the same teeth according to Lewis and Garn (1960). Results: For the tooth 36, more subjects were observed in the control group with erupted teeth in stage H than in the case group (75.6% and 71.1%, respectively). For the tooth 37, more subjects were observed in the control group with erupted teeth in stage G than in the case group (40.0% and 35.6%, respectively). Statistically significant differences were not observed considering the techniques separately (p>0.05). Conclusion: Similar dental development was observed between DM1 and control patients. Forensic expertises in DM1 patients could be performed using radiographic techniques that assess the dental calcification stages.

Objective To explore the effect of different factors on strengthening the tissue culture seedlings and roots of Dendranthema morifolium ( Ramat) Tzvel. cv. Gongju, so as to provide experimental basis for establishing an in-vitro rapid propagation system of Dendranthema morifolium. Methods The experiment took Dendranthema morifolium ( Ramat) Tzvel. cv. Gongju tissue culture seedling as the studying object. By using tissue culture technology, different additives were added into the MS medium. Results In the seedling-strengthening culture medium, 150 mL/L of macro-element was beneficial to the growth of tissue culture seedlings of Dendranthema morifolium ( Ramat) Tzvel. cv. Gongju. The culture medium with 100 g/L of coconut milk added could obviously promote the growth of Dendranthema morifolium ( Ramat) Tzvel. cv. Gongju tissue culture seedlings. And activated carbon added to the rooting culture medium could induce the formation of tissue culture root system of Dendranthema morifolium ( Ramat) Tzvel. cv. The addition of α-naphthaleneacetic acid ( NAA) and indolebutyric acid ( IBA) at certain concentrations could promote the amount and the growth of the roots. Conclusion The tissue culture seedlings of Dendranthema morifolium ( Ramat) Tzvel. cv. Gongju are boosted by increasing the amount of macro-element, reducing the concentration of agar in the culture medium and adding coconut milk and growth hormones to the culture medium. The optimal rooting culture medium is a compound of 1/2MS, NAA 0.05 mg/L and IBA 0.05 mg/L.

Study on Callus Induction in Explant of Aquiliaria sinensis Root / 广州中医药大学学报

Objective To study the conditions of callus induction with the roots of Aquilaria sinensis as explants. Methods Two sources of roots of Aquiliaria sinensis were selected as the explants. The effects of sterilization methods and the combination of different concentrations of phytohormones on callus induction were evaluated. Results When Aquiliaria sinensis root seedling was sterilized in 0.01mg/mL HgCl2 solution for 3 minutes, the sterilized effect was the best. The optimal callus induction medium was MS+0.1 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) +0.1 mg/L 6-benzylaminopurine (6-BA). Aseptic Aquiliaria sinensis root seedling cultivated in callus induction medium containing MS+1.0 mg/L naphthalene acetic acid ( NAA) +0.8 mg/L 6-BA achieved the highest callus induction rate. Conclusion Callus can be induced from two sources of Aquilaria sinensis roots. The induction rate of callus is lower when the explant root seedling is cultivated using 2,4-D alone as inducer, and is increased when used together with 6-BA.

Objective To investigate the polyploid induction and identification of Nerviliae fordii for harvesting the polyploid plants. Methods The materials and methods for polyploid induction of Nerviliae fordii were screened separately by comparing the induction rates of rhizomes and bulbs under natural conditions and tissue culture environment, and by comparing soaking method with agar method. The effects of colchicine concentration ( 200, 300, 400, 300 mg/L), colchicine action time ( 7, 14, 21, 28 d), DMSO concentration ( 0, 10, 20, 40 mL/L) and KT concentration ( 0, 1.0, 2.0, 4.0 mg/L) on induction rate were observed by orthogonal design method. The polyploid induction in the treated plants was identified by morphology, cytology and chromosome methods. Results After the tissue culture rhizomes were treated with 300 mg/L colchicine, 10 mL/L DMSO, and 2.0 mg/L KT by agar method for 28 days, the polyploid induction rate arrived to 50%, showing better induction effect. The morphology of polyploid plants was characterized by giantism, and the leaf length, leaf width and plant height were respectively 152.17%, 158.67%and 60.90%of those of the diploid plants. The length, width and density of stoma of leaf epidermal cell as well as the number of chloroplast in the treated plants were 138.46%, 153.00%, 59.09% and 109.09% of those of the untreated plants. The results of chromosome identification showed that the amount of the tetraploid ( about 40) was 2 times of the diploid chromosome ( about 20) in the treated plants, proving that the achieved Nerviliae fordii was a tetraploid plant. Conclusion Polyploid plants of Nerviliae Fordii have been successfully obtained, which will supply evidence for improving species, richening seed-breeding resources, and selecting of improved seeds of Nerviliae fordii.
