Analysis of anticoagulant therapy and pharmaceutical care for a patient with obstetrical antiphospholipid syndrome complicated with HELLP syndrome / 药物流行病学杂志

A 37-year-old woman with obstetric antiphospholipid syndrome(OAPS)was admitted to hospital due to poorly controlled hypertensive.After admission,the patient's blood pressure fluctuated greatly(152-161/100-112mmHg),platelet count decreased progressively(65x109·L-1),with lactate dehydrogenase of 367 U·L-1,alanine aminotransferase of 121.8 U·L-1,and aspartate aminotransferase of 89 U·L-1,and the disease progressed to HELLP syndrome.The clinical pharmacists participated in the treatment of this patient,combined the patient's risk of thrombosis and bleeding,changes in platelet count,and pharmacokinetic characteristics of anticoagulant drugs to assist clinicians in formulating the individualized anticoagulant treatment plan in the perinatal period,and promptly stopped and started anticoagulant drugs,which effectively prevented the patient from the occurrence of thrombosis and postpartum hemorrhage complications.Meanwhile,based on evidence-based pharmacology,the clinical pharmacists analyzed the key points of pharmacological care for such patients during pregnancy and lactation.The standardized use of OAPS treatment drugs,such as hydroxychloroquine,aspirin and prednesone,have more advantages than disadvantages during pregnancy,but the corresponding adverse reactions need to be closely monitored.Enoxaparin does not accumulate in milk and can be used safely during lactation.The clinical pharmacists play an important role in guaranteeing the safety and effectiveness of medication for pregnant and lactation patients.

Simultaneous determination of bepotastine and hydroxychloroquine concentrations in human breast milk by LC-MS/MS / 中国药房

OBJECTIVE To establish a liquid chromatography-tandem mass spectrometry （LC-MS/MS） method for the simultaneous determination of bepotastine and hydroxychloroquine concentrations in human breast milk and apply it in clinical practice. METHODS The milk samples （50 μL） were precipitated with 200 μL methanol containing the internal standard （100 ng/mL chloroquine）， and the supernatant was taken for analysis after vortexing and centrifugation. The separation was performed on a Waters ACQUITY UPLC HSS T3 column with mobile phase consisted of 0.1% formic acid-10 mmol/L ammonium acetate solution （phase A） and methanol （phase B） at gradient elution of 0.35 mL/min. The injection volume was 2 μL， and the analysis time was 4 min. The detection of the analytes was performed by electrospray ionization in positive mode by multiple reaction monitoring with the transition of m/z 388.9→201.9 （bepotastine）， m/z 336.3→247.1 （hydroxychloroquine）， and m/z 320.2→247.2 （chloroquine）. The established LC-MS/MS method was researched in methodology and used to determine the drug concentrations in the breast milk of 1 case of lactating patient. RESULTS The linear range of bepotastine was 2-200 ng/mL（ r＝0.999）， and hydroxychloroquine was 50-1 000 ng/mL （r＝0.998）. The intra-assay and inter-assay precisions were both ≤15%， and the accuracy， extraction recovery， matrix effect， and stability all met the acceptance criteria for bioanalytical method validation. The concentration result of bepotastine and hydroxychloroquine in the breast milk of the lactating patient showed， after 2 h and 14 h， the concentrations of bepotastine in the breast milk of the patient were 34.95 ng/mL and 5.72 ng/mL； those of hydroxychloroquine were 211.92 ng/mL and 104.18 ng/mL， respectively. The relative infant doses were 1.83% and 0.56%， respectively. CONCLUSIONS The established method is simple， rapid， and sensitive. It is suitable for simultaneous determination of bepotastine and hydroxychloroquine concentrations in human milk and can provide reference for safe drug use during lactation.

Traditional Galactogogues and the Practices Related to Their Use by Post-Natal Women of India

@#Introduction: Traditional galactogogue recipes are still being used, though not widely, and scientific studies on their use are scanty. This research aimed to study commonly used traditional galactogogue-recipes using primary sources, to bring about nutritional enhancement in most popular recipes and compare the standard and nutrified galactogogue-recipes for nutrients, phytochemicals and sensory qualities. Methods: A cross-sectional survey was carried out among 120 mothers (older than 20 years) residing in Indian states of Rajasthan and Uttar-Pradesh in their 0-1 year of lactation period who consented to be a part of the study. Background-information and use of galactogogues was collected with the help of self-designed, pre-tested questionnaires. Nutritive-value (moisture, ash, protein, fat, dietary-fibre, carbohydrate, iron, and calcium) of two of the most popular galactogogues ajwain-laddu and harira were calculated to find out the nutrient(s) lacking in it. Ajwain-laddu was nutrified using whole milk-powder, drumstick leaves powder and additional amount of clarified-butter. Harira was nutrified using poppy-seeds, niger-seeds and carrots. Results: The commonly used galactogogues were ajwain-laddu, harira, Gond-laddu, and Sonth-laddu. There was a significant difference between nutrient content of standard and nutrified-recipes (p<0.05) whereas no statistical difference was observed for hedonic rating-scores (p>0.05). Conclusion: Mothers were consuming traditional galactogogues foods in order to increase milk production and strongly believed that regular consumption of galactogogues has enhanced their milk production. To optimize the nutritional value of galactogogues, it is advisable to integrate ingredients abundant in phytochemicals and micronutrients. This can be accomplished while preserving the authentic taste and presentation of these galactogogue-recipes.

Orthodontic treatment during pregnancy, lactation, and postmenopausal period: a questionnaire development

Abstract This study aimed to develop and validate a self-administered questionnaire in Brazilian Portuguese to verify the level of knowledge of orthodontists in the care of pregnant, lactating, and postmenopausal women, named "Considerations on Orthodontic Treatment during Pregnancy, Lactation, and Postmenopausal Periods." The development and validation of the questionnaire consisted of the following steps: a) item generation; b) item reduction; c) questionnaire design; and d) validity and reliability tests in a cross-sectional study with 258 orthodontists working in the field from different Brazilian states. A total of 60 orthodontists participated in test-retest over a mean period of 45 days. The preliminary questionnaire consisted of a total of 60 questions. After item reduction, 40 questions were selected for the final version of the questionnaire, with eight questions about pregnant women; six about lactating women; 18 about postmenopausal women, and eight about general knowledge in dentistry. Each item had three response options in the Likert scale format. Face and content validity analysis, reliability assessment through internal consistency (Cronbach's alpha and McDonald's omega), and test-retest reliability through the intraclass correlation coefficient (ICC) and Spearman's correlation coefficient were performed. Face and content validity indicated that the questionnaire was considered valid, objective, and easily understandable. The questionnaire had good internal consistency (Cronbach's alpha = 0.77; McDonald's omega = 0.78) and good test-retest reliability (ICC = 0.71; Spearman's correlation coefficient = 0.51). The questionnaire was considered valid and reliable to assess the level of knowledge of orthodontists in the care of pregnant, lactating, and postmenopausal women.

Desafios para o suporte à amamentação em homens transgêneros sob à luz da interseccionalidade / Intersectionality and challenges in support for chest-feeding transgender men

Resumo O objetivo deste artigo é apreender os desafios nas vivências dos usuários e profissionais de Banco de Leite Humano no atendimento a homens transgêneros no contexto da amamentação sob à luz da Interseccionalidade. Estudo qualitativo descritivo-exploratório a partir de entrevistas realizadas com seis profissionais do Banco de Leite Humano, que atenderam previamente homens trans no contexto de amamentação, e dois homens trans bissexuais, que amamentaram ao peito. Os dados foram tratados pela Análise Temática com auxílio do software Atlas.ti versão 9.0. Observam-se lacunas nas esferas educacionais, institucionais e na gestão, associadas a questões pessoais e sociais, que reproduzem um modelo pré-concebido normativo, desconsiderando as singularidades requeridas no atendimento à população trans no contexto da amamentação. A cisheteronormatividade e a supremacia do profissional operam em âmbitos pessoais, sociais e institucionais para a segregação de homens transgêneros nos serviços de suporte à amamentação. A análise interseccional destes desafios permite uma visão global dos fatores de segregação e a implementação de políticas públicas promotoras da justiça social.

Abstract This article tried, from an intersectional standpoint, to grasp the challenges experienced by health professionals and service users of human milk banks in provision of care for transgender men chestfeeding. This exploratory, descriptive qualitative study drew on interviews of six human milk bank staff, who had previously assisted trans men in relation to chestfeeding and two bisexual trans men, who chestfed. The data was treated by thematic analysis, supported by Atlas.ti software, version 9.0. Lacunas in the educational, institutional and management spheres, associated with personal and social issues, reproduce a pre-conceived normative model and disregard the special demands of providing chestfeeding care for the trans population. Cisheteronormativity and "professional supremacy" operate in personal, social and institutional respects to segregate transgender men in lactation support services. Intersectional analysis of these challenges affords an overall view of segregative factors and enables public policies to be introduced to promote social justice.

Lactation induction for transgender women and transfeminine people in health care: a scoping review / Indução da lactação para mulheres transgênero e pessoas transfemininas no cuidado à saúde: uma revisão de escopo

Abstract There are countless proven benefits of breastfeeding, and the demand for such a right in health for transfeminine people is rarely addressed in the literature, reinforcing inequities in health. The article aims to conduct a scoping review of lactation induction for transfeminine people in the health care context. Systematic literature review in six selected databases, looking for articles with terms related to lactation and transfeminine people. Data were extracted and analyzed, summarizing the main results in tables. Three hundred ninety articles were found. After the exclusion of the duplicates there was a selection by title/abstract and a following selection by the full reading of the remaining articles, considering the pre-determined exclusion and inclusion criteria. Twenty-one articles were included, published between 2018 and 2023. Among them, six are case reports with unprecedented information on the topic, and the others are publications in various formats. Lactation induction was achieved in all the case reports. There is a fragile and recent body of evidence affirming the success of lactation induction in transgender women. There is a necessity to support this demand by health professionals and robust studies to optimize necessary interventions.

Resumo São inúmeros os benefícios comprovados do aleitamento materno, e a demanda por tal direito em saúde para as pessoas transfemininas é pouco abordada na literatura, reforçando as iniquidades em saúde. O artigo objetiva realizar uma revisão de escopo sobre a indução da lactação para pessoas transfemininas no contexto de assistência à saúde. Revisão sistemática da literatura em seis bases de dados selecionadas, buscando artigos com termos relacionados à lactação e pessoas transfemininas. Os dados foram extraídos e analisados, resumindo os principais resultados em tabelas. Foram encontrados 390 artigos. Após a exclusão dos duplicados, procedeu-se à seleção por título/resumo e posterior seleção pela leitura na íntegra, considerando os critérios de exclusão e inclusão. Foram incluídos 21 artigos, publicados entre 2018 e 2023. Entre eles, seis são relatos de casos com informações inéditas sobre o tema, e os demais são publicações em diversos formatos. A indução da lactação foi alcançada em todos os relatos de casos. Existe um corpo de evidências frágil e recente que afirma o sucesso da indução da lactação em mulheres trans. Há necessidade de respaldar essa demanda por parte dos profissionais e estudos robustos para otimizar as intervenções necessárias.

Glutamato monosódico y suprasistema neuroendocrinoinmune murino

Introducción: El glutamato monosódico se emplea en humanos desde el pasado siglo como potenciador del sabor. Su inoculación parenteral en murinos durante el período neonatal causa lesiones en varios núcleos hipotalámicos. Objetivo: Describir los efectos del glutamato monosódico sobre el sistema neuroendocrinoinmune en murinos. Metodos: Se realizó una revisión de artículos de libre acceso en las bases de datos PubMed y SciELO entre enero de 2013 y julio de 2020. También se examinó el texto básico de la asignatura Sangre y Sistema Inmune de la carrera de medicina. Desarrollo: Con independencia de su efecto adictivo, varios estudios defienden la inocuidad del glutamato monosódico. Sin embargo, este compuesto puede atravesar la barrera hematoencefálica de neonatos de murinos, y ocasionar trastornos metabólicos, reproductivos y del sistema inmune. Conclusiones: El glutamato monosódico en roedores causa alteraciones en los órganos que integran el suprasistema neuroendocrinoinmune y, por tanto, afecta sus funciones homeostáticas. Los mecanismos patogénicos no se conocen con exactitud.

Introduction: Monosodium glutamate has been used in humans since the last century as a flavor enhancer. Its parenteral inoculation in murine during the neonatal period causes lesions in several hypothalamic nuclei. Objective: To describe the effects of monosodium glutamate on the neuroendocrine immune system in murine samples. Methods: A review of open access articles in the PubMed and SciELO databases was conducted between January 2013 and July 2020. The basic text of the Blood and Immune System course of the medical school was also reviewed. Development: Regardless of its addictive effect, several studies defend the safety of monosodium glutamate. However, this compound can cross the blood-brain barrier of murine neonates, causing metabolic, reproductive and immune system disorders. Conclusions: Monosodium glutamate in rodents causes alterations in the organs that make up the neuroendocrine-immune suprasystem and, therefore, affects their homeostatic functions. The pathogenic mechanisms are not known exactly.

Mecanismos neuroendocrinos a la base de la asociación entre salud mental materna y lactancia / Neuroendocrine mechanisms underlying the association between maternal mental health and breastfeeding

La lactancia materna es fundamental para la salud del infante y se ve influida por diversos factores, entre ellos la salud mental materna. En particular, las madres que tienen síntomas depresivos tienen mayor riesgo de presentar dificultades de lactancia y de interrumpir tempranamente la lactancia exclusiva y la lactancia en general. Por otra parte, la lactancia materna actúa como un factor protector de la salud mental materna en algunas circunstancias, en tanto las dificultades de lactancia tienen un impacto negativo en la salud mental de la mujer. La presente revisión describe algunos de los mecanismos fisiológicos que subyacen al establecimiento y la mantención de la lactancia, asociados a la prolactina, la oxitocina, la dopamina y la serotonina, así como a la experiencia de la lactancia y la presencia de dificultades en esta área, y como estas interactúan con las dificultades emocionales de la madre. Se ofrece un modelo integrativo que considera aspectos hormonales y fisiológicos para comprender la asociación compleja y bidireccional entre el establecimiento de una lactancia exitosa y la salud mental materna.

Breastfeeding is essential for infant health and development. It is influenced by multiple factors, including maternal mental health. In particular, mothers who present depressive symptoms are at greater risk of presenting breastfeeding difficulties and presenting shorter exclusive breastfeeding and breastfeeding in general. On the other hand, breastfeeding acts as a protective factor for maternal mental health in some circumstances. Also, breastfeeding difficulties have a negative impact on womens mental health. This review describes some of the physiological mechanisms underlying the establishment and maintenance of lactation, associated with prolactin, oxytocin, dopamine, and serotonin. As well as how the lactation experience and the presence of difficulties in this area interact with the mothers emotional functioning. An integrative model is proposed, which considers hormonal and physiological aspects involved in the complex and bidirectional association between breastfeeding successful establishment and maternal mental health.

Relatos en torno a la lactancia materna de las mujeres-madres-migrantes haitianas en Chile

Introducción: Desde hace ya una década, Haití se ha ubicado como uno de los principales países emisores de migración hacia Chile, dada la estabilidad económica y política del país. Esta migración, con fuerte tendencia a la feminización, significa un aumento de los nacimientos de hijos de madre haitiana en Chile. Desde ese lugar, las madres haitianas enfrentan un desencuentro cultural al desplegar sus prácticas de crianza que involucran a la lactancia materna, en un Chile que promueve políticas homogeneizadoras de crianza infantil que, además, construye un discurso estereotipado respecto a las madres haitianas como madres indiferentes e ignorantes. Objetivo: Describir las experiencias y significados atribuidos a la lactancia materna por un grupo de madres haitianas residentes en la ciudad de Santiago de Chile. Métodos: Se realizó un estudio cualitativo, con enfoque interseccional, que describe las relaciones asimétricas entre la sociedad chilena y las mujeres madres haitianas con ocasión de la crianza de sus hijos en Chile, producto de las características de clase, género, etnia/raza que en ellas se encarnan. Resultados: Se obtuvieron tres categorías de análisis: las experiencias de amamantamiento, el significado atribuido a la lactancia materna y las formas de socialización a través de las cuales las madres haitianas han aprendido a amamantar. Conclusiones: En cuanto a la lactancia materna, las mujeres haitianas entrevistadas atraviesan diversas experiencias y atribuyen un sentido positivo a la leche materna como alimento vital para el fortalecimiento de sus hijos, y en cuya práctica despliegan conocimientos propios y también los aprendidos del sistema de salud chileno en una especie de mixtura. Si bien estos hallazgos no difieren de los resultados obtenidos en investigaciones con otros grupos de madres de origen no haitiano, el esencialismo hacia las prácticas de lactancia materna de las madres haitianas estaría basado en su etnia/raza y su pertenencia a grupos sociales vulnerables que las ubican en una posición social de subalternidad y, por tanto, factible de ser desvalorizado y gobernado.

Introduction: For a decade now, Haiti has been one of the main countries sending migration to Chile, given the country's economic and political stability. This migration, with a strong tendency towards feminization, means an increase in the births of children to Haitian mothers in Chile. From that place, Haitian mothers face a cultural disparity when deploying their parenting practices that involve breastfeeding, in Chile that promotes homogenizing child rearing policies that, in addition, constructs a stereotyped discourse regarding Haitian mothers as indifferent and ignorant mothers. Objective: To describe the experiences and meanings attributed to breastfeeding by a group of Haitian mothers residing in the city of Santiago de Chile. Methods: A qualitative study was carried out, with an intersectional approach, which describes the asymmetric relationships between Chilean society and Haitian mothers dedicated to raising their children in Chile in terms of the characteristics of class, gender, ethnicity/race that in these women incarnate. Results: Three categories of analysis were obtained: breastfeeding experiences, the meaning attributed to breastfeeding and the forms of socialization through which Haitian mothers have learned to breastfeed. Conclusions: Regarding breastfeeding, the Haitian women interviewed go through various experiences and attribute positive meaning to breast milk as a vital food for the strengthening of their children, and in whose practice, they deploy their own knowledge and also the knowledge learned from the Chilean health system, in a kind of mixture. Although these findings do not differ from the results obtained in research with other groups of mothers of non-Haitian origin, the essentiality towards the breastfeeding practices of Haitian mothers would be based on their ethnicity/race and their belonging to vulnerable social groups placing them in a social position of subalternity and, therefore, likely to be devalued and governed.

Consumo alimentario en mujeres embarazadas, mujeres que dan de lactar y niños de 0 a 5 años. Centros de salud ciudad de La Paz - área urbana, 2018 / Food consumption in pregnant women, breastfeeding women and children from 0 to 5 years old. La Paz city health centers - urban area, 2018

OBJETIVO: Determinar el consumo de alimentos en mujeres embarazadas, mujeres que dan de lactar y niños de 0 a 5 años, atendidos en Centros de Salud de Primer Nivel en la ciudad de La Paz en el mes de septiembre de 2018. MATERIAL Y MÉTODOS: Estudió transversal descriptivo correlacional en 126 mujeres embarazadas, 120 mujeres que dan de lactar, 105 niños de 0 a 5 meses y 117 niños de 6 a 60 meses, que asistieron a consulta en Centros de Salud. Se aplicó el método de Recordatorio de 24 Horas (R24H) para determinar el consumo de alimentos, método antropométrico para la evaluación nutricional. RESULTADOS: La ingesta promedio en mujeres embarazadas 1999 kcal y mujeres que dan de lactar 1943 Kcal, es menor a la recomendada; inadecuada en grasas, calcio y zinc; suficiente en proteínas, hidratos de carbono, vitaminas A y C; el hierro es deficiente en embarazadas. Los niveles de adecuación de la dieta en niños de 6 a 23 meses en calcio 88,3%, hierro 75%. De 24 a 60 meses en: calorías 86,3%, grasas 46,9% y zinc 50,6%. CONCLUSIONES: El consumo promedio observado en mujeres y niños es inferior a las recomendaciones nutricionales. El estado nutricional no corresponde al exceso o déficit en la ingesta. La ingesta deficiente de micronutrientes, es debida al consumo insuficiente de verduras y frutas.

Prevalência de aleitamento materno exclusivo e fatores associados em um município do extremo sul catarinense / Prevalence of exclusive breastfeeding and associated factors in a city of southern of Santa Catarina State, Brazil

Identificar a prevalência de aleitamento materno exclusivo e fatores relacionados durante os seis primeiros meses de vida do lactente. Trata-se de um estudo transversal realizado com 102 nutrizes residentes no município de Balneário Gaivota(SC) que efetivaram o pré-natal na rede pública ou privada e tiveram parto no ano de 2018. Os dados foram coletados por aplicação de questionário contemplando as variáveis sociodemográficas, gestacionais e pós-gestacionais. A prevalência de aleitamento materno exclusivo foi de 43,1%. Aqueles bebês que usavam mamadeira tiveram 45% menos probabilidade de ter recebido aleitamento materno exclusivo até os 6 meses de idade, e aqueles que receberam prescrição de fórmula infantil na alta hospitalar apresentaram 54% menos chance comparados aos seus pares. Os fatores relacionados ao aleitamento materno exclusivo são comportamentais e modificáveis, sendo necessária a orientação pelos profissionais de saúde durante a consulta pré-natal, puericultura e no acompanhamento do desenvolvimento infantil.

To identify the prevalence of exclusive breastfeeding and its related factors during the first six months of the infant's life. This is a cross-sectional study carried out with 102 nursing mothers residing in the city of Balneário Gaivota( SC) who performed prenatal care in the public or private network and gave birth in 2018. Data were collected by application of a questionnaire and included sociodemographic, gestational and post-gestational variables. The prevalence of exclusive breastfeeding was 43.1%. Those babies who used a bottle were 45% less likely to have been exclusively breastfed up to six months of age, and those who were prescribed infant formula at hospital discharge were 54% less likely compared to their peers. Factors related to exclusive breastfeeding are behavioral and modifiable, thus, guidance by health professionals is necessary during prenatal and childcare consultations and in the monitoring of child development.

Safety and Efficacy of a Combination of Amino Acids in Insufficient Lactating Mothers

Milk production of the mammary gland is mainly determined by the milk synthesis and proliferation abilities of mammary epithelial cells (MECs). The availability of amino acids is critical for the production of milk. Amino acids enhance milk protein synthesis and mammary gland development through the mechanistic target of rapamycin (mTOR) pathway. Taurine enhances lactation by increasing prolactin secretion. Vitamins such as Thiamine and Pyridoxine are essential for maintaining and growing maternal and child health. However, there is a paucity of data regarding the safety and efficacy of amino acids and vitamins combination in lactating mothers with insufficient lactation. Hence, a prospective study was conducted to assess the safety and efficacy of a novel amino acids and vitamins combination. The results showed that with the intervention of this combination, 62% of participants showed onset of lactation within 45 minutes to 2 hours. The study suggests clinicians should consider this novel combination to improve lactation in insufficient lactating mothers

Effects of auricular thumbtack needle on lactation function and TDP-43/Btn1A1/XDH pathway in primiparous women with cesarean section / 中国针灸

OBJECTIVE@#To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression.@*METHODS@#One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO18), Xiong (AH10), Xiongzhui (AH11), Shenmen (TF4), and Jiaogan (AH6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH.@*RESULTS@#After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05).@*CONCLUSION@#The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

A study of the influence of the level of transvaginal birth experience on the timing of postpartum lactation initiation / 中国实用护理杂志

Objective:To investigate the current status of women′s level of birth experience and lactation initiation time and explore the effect of level of birth experience on lactation initiation time.Methods:This was a cross-sectional study. A convenience sampling method was used to select 622 maternal cases attending the Affiliated Hospital of Jining Medical College from November, 2020 to January, 2021, and the distribution of their labor experience level and lactation initiation time was investigated by questionnaire and follow-up assessment.Results:There were 622 women with transvaginal deliveries who had lactation initiation times of more than 72 h in 241 cases (38.75%). The scores for each dimension of the Childbirth Experience Questionnaire (CEQ) were (49.63 ± 8.58)points, and the scores for each dimension of CEQ were perceived safety, professional support, involvement and self-efficacy in descending order. The results of the correlation analysis showed that there was a negative correlation between the scores on each dimension of CEQ and the total score and lactation initiation time ( r values were -0.436 to -0.146, all P<0.01). Stratified regression analysis showed that after controlling for age, number of births, gestational weeks of labour, illness during pregnancy and labour analgesia as the underlying variables affecting lactation initiation time, the scores for self-efficacy, involvement, perceived safety and professional support in the CEQ all affected lactation initiation time after delivery ( t values were -6.76 to -2.02, all P<0.05). Conclusions:The birth experience and lactation of women who deliver via vaginal birth need to be taken into account. The more negative the birth experience, the longer the lactation initiation time. The women′s involvement in the birth process, their own competence, perceived safety and level of professional support are all valid influencing indicators of lactation initiation time.

Status and influencing factors of delayed onset of lactogenesis Ⅱ in mothers of preterm infants / 中华围产医学杂志

Objective:To investigate the incidence of delayed onset of lactogenesis Ⅱ (DOL Ⅱ) in mothers of preterm infants and its influencing factors.Methods:This retrospective cohort study involved women who delivered prematurely at the Department of Obstetrics of the First Affiliated Hospital of Zhengzhou University from September 2021 to March 2022. Demographic and perinatal data of the subjects were collected. According to lactation outcome on the third day after delivery, these women were divided into DOL Ⅱ and non-DOL Ⅱ groups. The two groups' differences in general conditions were compared, and the potential factors influencing DOL Ⅱ were also analyzed. Chi-square test, two independent samples t-test, Mann-Whitney U test, and logistic regression analysis were used for statistical analysis. Results:There were 286 mothers of premature infants enrolled in this study, and 73 (25.5%) of them experienced DOL Ⅱ. The other 213 cases without DOL Ⅱwere included as the non-DOL Ⅱ group. Univariate analysis showed significant differences between the DOL Ⅱ and non-DOL Ⅱ groups in the following aspects: the proportion of women with adverse pregnancy history [28.8% (21/73) vs 41.8% (89/213), χ2=3.89], the proportion of primiparas [60.3% (44/73) vs 38.0% (81/213), χ2=10.93], the incidence of hypertensive disorders of pregnancy [35.6% (26/73) vs 16.4% (35/213), χ2=11.92], the time to initiate breastfeeding after birth[5.0 h (3.0-7.0 h) vs 4.0 h (2.0-5.0 h), Z=－4.27], and the frequency of breastfeeding or pumping within 48 h after delivery [7.0 times (6.0-9.0 times) vs 9.0 times (7.0-11.0 times), Z=－3.62] (all P<0.05). Multivariate logistic regression showed that primipara ( OR=2.720, 95% CI: 1.485-4.982), hypertensive disorders of pregnancy ( OR=3.178, 95% CI: 1.609-6.274), the time to initiate breastfeeding ( OR=1.394, 95% CI: 1.211-1.604) and the frequency of breastfeeding/pumping within 48 h after delivery ( OR=0.861, 95% CI: 0.772-0.962) were independent influencing factors for DOL Ⅱ (all P<0.05). Conclusions:?The factors that influence the occurrence of DOL Ⅱ in preterm mothers are primipara hypertensive disorders of pregnancy, breastfeeding initiation time after delivery, and the frequency of breastfeeding or pumping within 48 h postpartum.
