Fatores associados à deficiência de vitamina D em mulheres gestantes e lactantes / Factores asociados a la deficiencia de vitamina D en mujeres embarazadas y lactantes / Factors associated with vitamin d deficiency in pregnant and lactatingwomen

Introdução: A deficiência de vitamina D durante a gestação e a lactação pode repercutir negativamente no desenvolvimento fetal e infantil, devido seu papel fundamental nos sistemas imunológico, cardíaco, ósseo, muscular e neural. Objetivo: Realizar uma revisão de literatura para integrar estudos que evidenciam a deficiência de vitamina D em gestantes e lactantes, e os fatores de risco associados a essa carência. Metodologia: Foi realizado um levantamento bibliográfico entre agosto e outubro de 2021, com atualização entre outubro e novembro de 2022 através de pesquisas às bases Pubmed e Scielo, bem como às listas de referências dos artigos selecionados. Foram empregados os descritores consumo alimentar, vitamina D, deficiência de vitamina D, gestantes e lactantes, usando-se o operador booleano AND para a associação entre eles. Como critérios de inclusão foram adotados o tipo de estudo (epidemiológicos, ensaios clínicos e revisões integrativa e sistemática), o idioma (espanhol, inglês e português) e o período de publicação (2010 a 2022). Resultados: Evidenciou-se que existem vários fatores de riscos para a inadequação do status de vitamina D em gestantes e lactantes como a baixa exposição da pele à luz solar e fatores relacionados (uso excessivo de protetor solar, menor tempo de atividades ao ar livre, clima, religião e hábitos culturais, maior escolaridade);a pigmentação mais escura da pele; o baixo consumo alimentar de vitamina D e variáveis associadas; a menor idade materna; o primeiro trimestre gestacional; a primiparidade e o excesso de tecido adiposo. Conclusões: Em gestantes e lactantes, a carência de vitamina D associa-se a distintos fatores, com destaque principalmente para a baixa exposição à luz solar, a pigmentação mais escura da pele e o excesso de tecido adiposo, sendo de extrema importância que sejam abordados com cautela, visando ações voltadas a variáveis modificáveis, de modo a auxiliar na redução da hipovitaminose D nestes grupos (AU).

Introduction: Vitamin D deficiency during pregnancy and breastfeeding can have a negative impact on fetal and infant development due to its fundamental role in the immune, cardiac, bone, muscular and neural systems. Objective: To conduct a literature review to integrate studies which show the Vitamin D deficiency in pregnant andlactating women, and the risk factors associated with this deficiency. Methodology: A bibliographic survey was carried out between August and October 2021, with an update between October and November 2022 through searches in the Pubmed and Scielo databases, as well as the reference lists of the selected articles. The descriptors food consumption, vitamin D, vitamin D deficiency, pregnant and lactating women were used, using the Boolean operator AND for the association between them. The type of study (epidemiological, clinical trials and integrative and systematic reviews), language (Spanish, English and Portuguese) and publication period (2010 to 2022) was adopted as inclusion criteria.Results:It was shown that there are several risk factors for inadequate vitamin D status in pregnant and lactating women, such as low skin exposure to sunlight and related factors (excessive use of sunscreen, less time spent outdoors, climate, religion and cultural habits, higher education); darker skin pigmentation; low dietary intake of vitamin D and associated variables; the lowest maternal age; the first gestational trimester; primiparity and excess adipose tissue.Conclusions: Vitamin D deficiency in pregnant and lactating women is associated with different factors, witha main emphasis on low exposure to sunlight, darker skin pigmentation and excess adipose tissue. Furthermore, it is extremely important that these factors are approached with caution, implementing actions aimed at modifiable variables in order to help reduce hypovitaminosis D in these groups (AU).

Transição para a maternidade não planejada após os 35 anos: teoria de situação específica / Transition to unplanned motherhood after age 35: situation-specific theory

Resumo: A saúde sexual e reprodutiva é um pilar fundamental do sistema de saúde brasileiro, assinalando a importância das políticas públicas e programas voltados para a promoção dos direitos sexuais e reprodutivos. Nessas políticas, mulheres com 35 anos ou mais recebem pouca ou nenhuma atenção em relação a esse tema, pois as políticas estão voltadas para prevenção de doenças. Há uma crescente prevalência de gravidezes não planejadas nessa faixa etária e estudos não têm conseguido apreender conhecimentos acerca das experiências de mulheres que vivenciam a transição para a maternidade não planejada em idade avançada, a fim de aprimorar o cuidado a essas e promover uma transição bem-sucedida. Assim, o objetivo deste estudo foi desenvolver uma Teoria de Situação Específica para o cuidado de Enfermagem à mulher com 35 anos ou mais em transição para a maternidade de uma gestação não planejada, a partir da Teoria das Transições. O estudo caracteriza-se como teórico-exploratório de natureza qualitativa, que utilizou a Abordagem Integrativa para o desenvolvimento de Teorias de Situação Específica em enfermagem, guiada pela estratégia teoria-pesquisa-teoria, de Afaf Meleis. O processo metodológico envolveu um exercício reflexivo dedutivo, iniciando com a derivação dos conceitos centrais da Teoria das Transições. Seguiu-se a indução por meio de pesquisa de campo qualitativa, com entrevistas semiestruturadas de seis gestantes que não planejaram a gestação, com média de idade de 41 anos, ocorridas entre julho de 2022 a julho de 2023 no prénatal de alto risco de um hospital universitário do Sul do Brasil. Ainda indutivamente, produziuse dados a partir da reanálise de uma dissertação de Mestrado do grupo de pesquisa, bem como de revisão integrativa da literatura e da experiência com pesquisas prévias no tema, a fim de fundamentar o desenvolvimento da Teoria de Situação Específica. Foram desenvolvidas a partir disso declarações do metaparadigma, pressupostos e proposições. A teoria desenvolvida explica a transição para a maternidade não planejada em mulheres com 35 anos ou mais, contextualizando-a como um fenômeno social complexo, influenciado por fatores socioeconômicos, culturais, individuais e coletivos. A teoria explica como a maternidade tardia, especialmente quando não planejada, emerge como um papel em constante transformação, permeado por percepções diversas sobre o significado de ser mãe nessa fase da vida, desafiando frequentemente expectativas e crenças prévias. À medida que a experiência se amplia, concepções anteriores sobre a maternidade são questionadas, e novas são formadas, conduzindo a um processo de empoderamento e redefinição pessoal. Esta transição para a maternidade, marcada pela pluralidade de perspectivas e experiências, destaca a complexidade e a individualidade de cada mulher. Foi desenvolvida uma representação gráfica com as relações entre as declarações do metaparadigma., assim como nove proposições e cinco pressupostos. Esta teoria se baseia em vertentes do conhecimento científico atual para justificar sua construção, ressaltando a importância de compreender as experiências humanas e os contextos sociais onde ocorrem. A Teoria de Situação Específica atingiu o objetivo na medida em que propõe uma estrutura teórica em que o cuidado de enfermagem facilita os processos de transição e promove a interação entre cliente, ambiente, saúde e enfermagem. Além disso, possibilita que o enfermeiro provoque e estimule mudanças significativas nos resultados das transições por meio das terapêuticas de cuidado de enfermagem, evidenciando a necessidade de um cuidado personalizado e contextualizado, que leve em consideração a complexidade das experiências de maternidade tardia não planejada.

Abstract: Sexual and reproductive health is a fundamental pillar of the Brazilian healthcare system, highlighting the importance of public policies and programs aimed at promoting sexual and reproductive rights. In these policies, women aged 35 and older receive little or no attention regarding this issue, as the policies are focused on disease prevention. There is an increasing prevalence of unplanned pregnancies in this age group, and studies have not been able to capture knowledge about the experiences of women undergoing the transition to unplanned motherhood at an older age, in order to improve care for these women and promote a successful transition. Therefore, the aim of this study was to develop a Specific Situation Theory for nursing care of women aged 35 and older transitioning to motherhood from an unplanned pregnancy, based on the Transition Theory. The study is characterized as theoretical-exploratory with a qualitative nature, using the Integrative Approach for the development of Specific Situation Theories in nursing, guided by Afaf Meleis's theory-research-theory strategy. The methodological process involved a deductive reflective exercise, starting with the derivation of the central concepts of the Transition Theory. This was followed by induction through qualitative field research, with semi-structured interviews of six pregnant women who had unplanned pregnancies, with an average age of 41 years, conducted between July 2022 and July 2023 in the high-risk prenatal care of a university hospital in Southern Brazil. Inductively, data was also generated from the reanalysis of a master's thesis from the research group, as well as from an integrative literature review and experience with previous research on the topic, to support the development of the theory. From this, metaparadigm statements, assumptions, and propositions were developed. The developed theory explains the transition to unplanned motherhood in women aged 35 and over, contextualizing it as a complex social phenomenon, influenced by socioeconomic, cultural, individual, and collective factors. The theory elucidates how late motherhood, especially when unplanned, emerges as a role in constant transformation, permeated by diverse perceptions about the meaning of being a mother at this stage of life, often challenging previous expectations and beliefs. As the experience broadens, previous conceptions about motherhood are questioned, and new ones are formed, leading to a process of empowerment and personal redefinition. This transition to motherhood, marked by a plurality of perspectives and experiences, highlights the complexity and individuality of each woman. A graphic representation of the relationships between the metaparadigm statements was developed, along with nine propositions and five assumptions. This theory is based on strands of current scientific knowledge to justify its construction, emphasizing the importance of understanding human experiences and the social contexts in which they occur. The Specific Situation Theories achieved its objective insofar as it proposes a theoretical framework in which nursing care facilitates transition processes and promotes the interaction between client, environment, health, and nursing. Moreover, it enables the nurse to provoke and stimulate significant changes in transition outcomes through nursing care therapeutics, highlighting the need for personalized and contextualized care that considers the complexity of the experiences of unplanned late motherhood.

Prevención de la preeclampsia y su relevancia en el contexto latinoamericano: una revisión narrativa

La preeclampsia es un trastorno hipertensivo de la gestación que se evidencia durante las últimas semanas de esta. Globalmente, la preeclampsia es la segunda causa de mortalidad materna. Se estima que su incidencia es de aproximadamente un 16% en los países en vías de desarrollo, y llega a superar el 25% en algunos países de Latinoamérica. Se describirán las principales estrategias de prevención de la preeclampsia y su relevancia en el contexto latinoamericano. La búsqueda de información tuvo lugar en PubMed y BVS para las publicaciones realizadas sobre prevención de la preeclampsia, utilizando la expresión de búsqueda (“Disease Prevention” OR “Primary Prevention”) AND (Pre-eclampsia OR Preeclampsia OR “Pre eclampsia”) AND (“Latin America” OR “Central America” OR “South America” OR Caribbean). En PubMed se encontraron 60 y en BVS 42 resultados que responden a la expresión de búsqueda, y fueron seleccionados 18 artículos que discuten estrategias de prevención de la preeclampsia en Latinoamérica. Con estos resultados, se pueden afirmar que, describir las mejores estrategias de prevención de la preeclampsia en Latinoamérica es una tarea pendiente, pues existe una relativa carencia de publicaciones. En consecuencia, se espera que esta revisión motive futuras investigaciones y sea un recurso útil en la actualización médica.

Preeclampsia is a hypertensive disorder of pregnancy that is evident during the last weeks of it. Globally, preeclampsia is the second leading cause of maternal mortality. It is estimated that the incidence is approximately 16% in developing countries, and reaches over 25% in some Latin American countries. The main strategies for the prevention of preeclampsia and their relevance in the Latin American context will be described. The search for information took place in PubMed and BVS for publications on preeclampsia prevention, using the search expression (“Disease Prevention” OR “Primary Prevention”) AND (Pre-eclampsia OR Pre-eclampsia OR “Pre eclampsia”) AND (“Latin America” OR “Central America” OR “South America” OR Caribbean). In PubMed we found 60 and in VHL 42 results that respond to the search expression, and 18 articles were selected that discuss prevention strategies for preeclampsia in Latin America. With these results, it is possible to afirm that describing the best strategies for the prevention of preeclampsia in Latin America is a pending task, since there is a relative lack of publications. Consequently, it is hoped that this review will motivate future research and be a useful resource in medical updating.

Resultados: Hubo predominio de las gestantes en todos los grupos de edades (58,9 %) en relación con las puérperas (41,1 %), principalmente en el grupo etario de 31-35 años (30,3 %). La hipertensión arterial resultó ser la comorbilidad más frecuente con 71,4 y 28,6 %, para embarazadas y puérperas, respectivamente; en tanto, 66,6 % de las primeras y 33,3 % de las segundas fueron ingresadas por neumonía. Todas las embarazadas egresaron vivas y 7 puérperas fallecieron. La tasa de letalidad fue de 12,5 y el síndrome de disfunción multiorgánica apareció en 57,2 % de las afectadas. Conclusiones: La hipertensión arterial fue la comorbilidad más frecuente, la neumonía viral, el principal diagnóstico al ingreso y el síndrome de disfunción multiorgánica, la primera causa directa de muerte.

Introduction: Infection due to SARS-CoV-2 virus has become a pandemic that has caused great number of complications and is usually fatal for pregnant and newly-delivered women. Objective: To describe the clinical and epidemiological characteristics of pregnant and newly-delivered women with Covid-19 admitted to intensive care units. Methods: An observational descriptive, cross-sectional study of 56 pregnant and newly-delivered women with confirmed diagnosis of Covid-19 was carried out; they were admitted to the Intensive Care Unit of Dr. Joaquín Castillo Duany Teaching Provincial Hospital in Santiago de Cuba during 2021. The analyzed variables were age, past health history, cause of admission, state when discharged from the institution and the main cause of death. For this purpose, the frequencies, percentages and case fatality rate were calculated. Results: There was a prevalence of pregnant women in all the age groups (58.9%) relative to the newly-delivered women (41.1%), mainly in the 31- 35 age group (30.3%). Hypertension was the most frequent comorbidity with 71.4 and 28.6%, for pregnant and newly-delivered women, respectively; as long as, 66.6% of the first ones and 33.3% of the second ones were admitted due to pneumonia. All the pregnant women were discharged alive and 7 newly-delivered women died. Case fatality rate was 12.5 and multiple organ dysfunction syndrome appeared in 57.2% of those affected. Conclusions: Hypertension was the most frequent comorbidity, viral pneumonia was the main admission diagnosis and multiple organ dysfunction syndrome, the first direct cause of death.

Importancia de las determinaciones inmunohematológicas en el control prenatal de gestantes con grupo sanguíneo RhD negativo

La guía para la atención prenatal es el marco regulatorio de las normas de obstetricia para el control y cuidado de las gestantes, con énfasis en aquellas que poseen el grupo sanguíneo RhD negativo. La aloinmunización por anti-D es la causa más frecuente y grave de la enfermedad hemolítica del recién nacido. Para un diagnóstico temprano de la embarazada con dicho grupo sanguíneo, resulta necesario determinar los anticuerpos antieritrocitarios involucrados. En la presente comunicación se resalta la función del laboratorio de inmunohematología en el seguimiento de la gestante con grupo de sangre RhD negativo.

The guide for prenatal care is the regulatory mark of obstetrics norms for the control and care of pregnant women, with emphasis on those who have the RhD negative blood group. Alloimmunization by anti-D is the most frequent and serious cause of hemolytic disease of the newborn. For an early diagnosis of the pregnant woman with said blood group, it is necessary to determine the red blood cell antibodies involved. This communication highlights the role of the immunohematology laboratory in the follow-up of pregnant woman with RhD negative blood type.

Asociación del bajo peso al nacer con el control prenatal, la anemia materna y ser madre soltera

Fundamento: la elevada frecuencia de recién nacidos con peso inferior al adecuado, en relación con la anemia materna, la atención prenatal insuficiente y la condición de madre soltera, puede tener importantes repercusiones en la salud de las madres y los niños. Objetivo: identificar la relación entre el control prenatal, la anemia materna y la condición de ser madre soltera con el bajo peso al nacer de los infantes. Método: se realizó un estudio observacional, analítico y retrospectivo de casos y controles en gestantes atendidas en un hospital de la región Sierra de Ecuador durante el año 2022. La muestra fue de 280 pacientes. El grupo de casos lo conformaron las gestantes con hijos con bajo peso al nacer (n = 70) y el grupo de control por gestantes con recién nacidos con peso normal (n = 210). Se realizó la prueba de Chi cuadrado de independencia y se calculó el Odds Ratio y su intervalo de confianza del 95 % para el nivel de asociación entre las variables. Resultados: la relación de la variable asistencia a controles prenatales con respecto al bajo peso al nacer mostró una asociación protectora (OR = 0,5). Se identificaron como factores de riesgo, la anemia materna (OR = 3,1) y la condición de madre soltera (OR = 2,3) por sus altos valores de asociación positiva y directa. Conclusiones: el control prenatal, la anemia materna y la condición de madre soltera resultaron tener un nivel de asociación significativa con el bajo peso al nacer.

Foundation: the high frequency of newborns with less than adequate weight, in relation to maternal anemia, insufficient prenatal care and single mother status, can have important repercussions on the health of mothers and children. Objective: to identify the relationship between prenatal control, maternal anemia and the condition of being a single mother with low birth weight of infants. Method: an observational, analytical and retrospective case-control study was carried out in pregnant women treated in a hospital in the Sierra region of Ecuador during the year 2022. The sample was 280 patients. The case group was made up of pregnant women with children with low birth weight (n = 70) and the control group was made up of pregnant women with newborns with normal weight (n = 210). The Chi square test of independence was performed and the Odds Ratio and its 95 % confidence interval were calculated for the level of association between the variables. Results: the relationship between the variable attendance at prenatal check-ups and low birth weight showed a protective association (OR = 0,5). Maternal anemia (OR = 3,1) and being a single mother (OR = 2,3) were identified as risk factors due to their high values of positive and direct association. Conclusions: prenatal control, maternal anemia and single mother status turned out to have a significant level of association with low birth weight.

Perfil clínico e epidemiológico de gestantes que vivem com HIV na Macrorregião Sul de Saúde de Santa Catarina / Clinical and epidemiological profile of pregnant women living with HIV in the Southern Health Macroregion of Santa Catarina

Objetivo: Nos últimos anos, a epidemia de HIV tem incidido consideravelmente e de forma silenciosa na população de mulheres gestantes, sobretudo devido à subnotificação, ao diagnóstico tardio e à negligência quanto à realização de teste anti-HIV pelas infectadas. Diante disso, este estudo tem por objetivo descrever o perfil clínico e epidemiológico de gestantes que vivem com HIV na Macrorregião Sul de Saúde de Santa Catarina. Métodos: Trata-se de um estudo ecológico, ana- lítico, retrospectivo, com base em dados secundários retirados das plataformas Sistema de Informações de Agravos de Notificação (Sinan) e Sistema de Monitora- mento Clínico das Pessoas Vivendo com HIV/AIDS (SIMC), acerca de gestantes que vivem com HIV na Macrorregião Sul de Saúde de Santa Catarina, no período entre 2019 e 2022. Resultados: A partir dos dados sociodemográficos, obteve-se um perfil epidemiológico prevalente de mulheres com idade entre 30 e 49 anos, brancas, com baixo nível de escolaridade e entre 1 a 13 semanas de gestação no momento da notificação de infecção por HIV. O perfil clínico apontou para a prevalência de mulheres em uso de terapia antirretroviral, com carga viral acima de 1.000 cópias/ mL e contagem de linfócitos T-CD4+ superior a 350 células/mm3. Conclusão: Apesar do baixo nível de escolaridade e da elevada carga viral, o resultado foi positivo para a população selecionada, uma vez que foi demonstrada boa adesão ao tra- tamento e alta contagem de linfócitos, sendo esses bons preditores de evolução clínica para o HIV.

Objective: In recent years, the HIV epidemic has significantly and silently affected the population of pregnant women, mainly due to underreporting, late diagnosis, and neglect of HIV testing among infected individuals. In light of this, the aim of this study is to describe the clinical and epidemiological profile of pregnant women living with HIV in the Southern Health Macroregion of Santa Catarina. Methods: This is an ecological, analytical, retrospective study based on secondary data retrieved from the Notifiable Diseases Information System (Sinan) and the Clinical Monitoring System for People Living with HIV/ AIDS (SIMC), regarding pregnant women living with HIV in the Southern Health Macroregion of Santa Catarina from 2019 to 2022. Results: Based on sociodemographic data, a prevalent epidemiological profile was identified, with women aged 30 to 49 years, white, with low educational level, and between 1 to 13 weeks of gestation at the time of HIV infection notifica- tion. The clinical profile revealed a prevalence of women on antiretroviral therapy, with a viral load above 1,000 copies/ mL and a T-CD4+ lymphocyte count above 350 cells/mm3. Conclusion: Despite the low educational level and high viral load, the outcome was positive for the selected population, as good treatment adherence and high lymphocyte count were demonstrated, both of which are good predictors of clinical progression for HIV.

Clinical features of critically ill pregnant and parturient women infected with chronic hepatitis B virus： An analysis of 41 cases / 临床肝胆病杂志

ObjectiveTo investigate the clinical features and outcomes of critically ill pregnant and parturient women with chronic hepatitis B virus （HBV） infection， and to provide clinical experience for the rescue of critically ill pregnant and parturient women and the prevention and treatment of the severe exacerbation of liver disease. MethodsA total of 41 pregnant and parturient women with chronic HBV infection who were admitted to Department of Critical Care Medicine， Nanjing Second Hospital， from March 2013 to March 2023 were enrolled in this study， and their clinical data were collected through the electronic medical record system of hospital to summarize the main causes of transfer to the intensive care unit （ICU）， the causes of death， and treatment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between two groups. ResultsAmong the 41 patients， 13 （31.71%） did not receive regular antenatal examination and 8 （19.51%） with a high viral load （HBV DNA ≥2×105 IU/mL） did not receive antiviral therapy. Cesarean section was the main mode of delivery in 32 patients （78.05%）； 23 patients （56.10%） had premature delivery， and 5 patients died （12.20%）. The top three causes of transfer to the ICU were liver failure， postpartum hemorrhage， and hypertensive disorders of pregnancy. Liver failure mainly occurred in late pregnancy， with hepatic encephalopathy as the most common complication （28.57%） and intrahepatic cholestasis of pregnancy as the most common comorbidity （21.43%）； among the 14 patients with liver failure， 6 （42.86%） received regular antenatal examination， and 13 （92.86%） did not receive antiviral therapy before admission. The mean length of ICU stay was 3.31±1.65 days for the patients with postpartum hemorrhage， among whom the patients with severe liver disease had coagulation disorders before delivery， which were difficult to correct after 48 hours of treatment. ConclusionPregnant and parturient women with chronic HBV infection tend to have complex conditions and a relatively high mortality rate. For pregnant and parturient women with chronic HBV infection， assessment of liver status， regular antenatal examination， and timely antiviral therapy are of vital importance to reduce severe exacerbation and mortality rate.

Survey on Regional Hierarchical and Transferal Management of Severe Post-partum Hemorrhage in Beijing / 实用妇产科杂志

Objective:To assess the current state of care for Severe Postpartum Hemorrhage(SPPH)in refer-ral centers and non-referral centers,and to propose enhanced strategies for the regional prevention and manage-ment of SPPH.Methods:The clinical data of patients with SPPH,defined as postpartum blood loss≥1500 ml or transfusion of blood products≥1000 ml,in two districts of Beijing from January 2021 to June 2023 were retrospec-tively analyzed.A total of 201 cases of SPPH were included and they were divided into 125 cases in the referral center group and 76 cases in the non-referral center group based on whether they were city level referral centers.The clinical characteristics between these two groups were compared.Furthermore,a stratified analysis was con-ducted using a Logistic regression model to identify the risk factors associated with massive postpartum hemor-rhage,defined as postpartum hemorrhage≥4000 ml,transfusion requirements exceeding suspended red blood cells(RBC)>10 U and(or)plasma>1000 ml.Results:Analysis of cases presenting with SPPH between the two study groups showed that patients in the referral center group exhibited advanced maternal age,smaller gestation-al weeks at delivery and a higher proportion of high-risk factors compared to those in the non-referral center group,and the difference was statistically significant(P<0.05).The primary cause of SPPH in the referral center group was placental factors,while uterine atony was identified as the main factor in the non-referral center group,and this difference was statistically significant(P<0.05).Additionally,within the non-referral center group,there was a higher amount of blood loss during cesarean section,lower proportion of B-Lynch suture/vascular suture ligation,and higher proportion of uterine packing(P<0.05).Furthermore,compared to the referral center group,there were significantly higher incidences of plasma transfution volume,return to operating room for further inter-vention or exploratory laparotomy procedures after initial delivery and complications related to postpartum hemor-rhage observed in the non-referral center group(P<0.05).Moreover,it was noted that there were more cases of massive postpartum hemorrhagic disease reported in the non-referral center group than in the referral center group(P<0.05).In massive postpartum hemorrhage cases analyzed,referring centers had a higher percentage of patients presenting with multiple high-risk factors for postpartum hemorrhage during pregnancy when compared to non-referring centers(71.4%vs.33.3%,P<0.05).Placental factors accounted for majority causes leading to hemorrhage within referring centers(57.1%),whereas both uterine atony and placental factors played major roles within non-referring centers′cases(42.9%,28.6%).The multivariate Logistic regression analysis revealed that non-referral center delivery(aOR 3.47,95%CI 1.40-9.18)and a history of multiple intrauterine operations(aOR 12.63,95%CI 1.24-131.30)were identified as significant risk factors for massive postpartum hemor-rhage.Conclusions:The outcomes of high-risk pregnant women referral management in the region exhibit an im-provement,necessitating the reinforcement of training in non-referral midwifery institutions regarding identification of high-risk factors,surgical suture techniques,and comprehensive SPPH management to avert excessive bleed-ing and blood transfusion.

The Influence of Late Pregnancy Perineal Massage Combined with Hip Training on Labor Outcomes and Psychological Elasticity of Primiparous Pregnant Women / 实用医学杂志

Objective To investigate the effects of perineal massage combined with hip joint exercise on the outcome of delivery and mental resilience of primipara.Methods 90 pregnant women in the third trimester(after 36 weeks)who obtained the knowledge about perineal massage from midwife clinic were randomly divided into two groups with 45 cases each.The control group received regular antenatal examination and family self-exercise;the experimental group received perineal massage and hip joint training combined treatment.The delivery outcome,birth experience and maternal mental resilience of the two groups were compared.Results the number of vaginal delivery in the experimental group were higher than that in the control group(P<0.05);the second stage of labor was significantly shorter than that of the control group(P<0.05);the perineal integrity rate was higher than that of the control group(P<0.05);the scores of all dimensions in delivery experience questionnaire were higher than that of the control group(P<0.05);the scores of all dimensions in maternal mental resilience were higher than those of the control group(P<0.05)after intervention.Conclusion The perineal massage which conducted by midwives combined with hip movement can effectively improve the quality of delivery,relieve the negative emotions of pregnant women,improve the psychological elasticity level of pregnant women,and improve the delivery outcomes.

Iodine nutrition status of key population in Fuzhou City in 2021 / 中华地方病学杂志

Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.

Survey and analysis of iodine nutrition status of children and pregnant women in Tengzhou City, Shandong Province from 2017 to 2021 / 中华地方病学杂志

Objective:To investigate the iodine nutrition status of key populations in Tengzhou City, Shandong Province, and provide a scientific basis for prevention and control of iodine deficiency disorders in the future.Methods:From 2017 to 2021, a stratified cluster sampling method was adopted, 21 iodine deficiency disorders towns (streets) in Tengzhou City were divided into 5 sampling areas based on east, west, south, north, and center, with 1 town (street) selected as the monitoring site from each area every year; 40-non boarding students aged 8 - 10 (half male and half famale, age balanced) from one primary school and 20 pregnant women (early, middle, late pregnancy balanced) were selected from each town (street), and their household salt and urine samples were collected for test of salt iodine and urine iodine contents.Results:A total of 1 506 household salt samples were collected, the median salt iodine was 24.29 mg/kg, the coverage rate of iodized salt was 96.55% (1 454/ 1 506), the qualified rate of iodized salt was 93.40% (1 358/1 454), and the consumption rate of qualified iodized salt was 90.17% (1 358/1 506). There were statistically significant differences in the median salt iodine and coverage rate of iodized salt among different years ( H = 119.61, P < 0.001; χ 2 = 14.53, P = 0.006). A total of 1 000 urine samples were collected from children aged 8 - 10, with a median urine iodine of 182.20 μg/L. The differences in urine iodine between different years, genders, ages, and urban and rural children were statistically significant ( H = 38.18, 13.96, 49.30, 8.34, P < 0.05). A total of 499 urine samples were collected from pregnant women, with a median urine iodine of 152.40 μg/L. There were statistically significant differences in the median urine iodine of pregnant women in different years ( H = 20.09, P < 0.001). Conclusions:The iodine nutrition of children and pregnant women in Tengzhou City is at an appropriate level. However, the consumption rate of qualified salt iodine and the urine iodine level of pregnant women are at the lower limit of the standard, and there are fluctuations, posing a risk of iodine deficiency. Relevant departments should focus on strengthening the management of iodized salt, monitoring iodine deficiency among key populations, and providing health education to achieve scientific iodine supplementation and sustained stable iodine nutrition suitability.

Effect of psychological intervention on postpartum depression / 中国基层医药

Objective:To investigate the effect of psychological intervention on postpartum depression.Methods:A total of 250 pregnant women who were hospitalized for delivery in the obstetrics ward of Jiaxing Maternity and Child Health Care Hospital from January 2021 to January 2022 were included in this randomized controlled study. The patients were randomly assigned to an observation group ( n = 125) and a control group ( n = 125) using a random number table. The observation group received psychological intervention, while the control group underwent routine ward rounds. Prior to and after intervention, the levels of depression [assessed by Edinburgh Postnatal Depression Scale (EPDS) score and Self-rating Depression scale (SDS) score] and anxiety [measured by Self-rating Anxiety Scale (SAS) score] were compared between the two groups. Results:Before intervention, the EPDS, SDS, and SAS scores in the observation group were (16.95 ± 4.20) points, (65.83 ± 7.52) points, and (61.12 ± 7.59) points, respectively. In the control group, these scores were (16.62 ± 4.03) points, (64.49 ± 7.98) points, and (60.88 ± 7.85) points, respectively. At 7 days post-discharge, the EPDS, SDS, and SAS scores in the observation group were (11.54 ± 2.39) points, (51.12 ± 4.62) points, and (49.71 ± 4.22) points, respectively. In the control group, these scores were (15.93 ± 3.87) points, (63.21 ± 6.95) points, and (59.65 ± 6.43) points, respectively. At 7 days post-discharge, the EPDS, SDS, and SAS scores in the observation group were significantly decreased compared with those before intervention ( t = 18.35, 27.09, 21.60, all P < 0.001). At 7 days post-discharge, the EPDS, SDS, and SAS scores in the observation group were significantly lower than those in the control group ( t = -10.79, -16.19, -14.44, all P < 0.001). There were no significant differences in EPDS, SDS, and SAS scores in the control group between before intervention and 7 days post-discharge ( t = 1.95, 1.91, 1.92, P = 0.051, 0.056, 0.055). Conclusion:Psychological intervention can effectively alleviate postpartum depression and anxiety in postpartum women and deserves clinical promotion.

Rationale for Contraindications for Pregnant and Breast-Feeding Women in the Package Inserts of Prescription Drugs and Changes in Information by the Revised Instructions / 社会薬学

The package inserts revision regarding prescription drugs is an ongoing process. In this study, we examined the status of this revision and how the content of the information provided has been updated with the new instructions, including the rationale for contraindications for pregnant and breast-feeding women. A total of 407 prescription drugs for pregnant and breast-feeding women were contraindicated, accounting for approximately 15% of the 2,627 nonproprietary names. The number of contraindicated drugs for pregnant, breast-feeding, and both pregnant and breast-feeding women were 406, 44, and 43, respectively. The majority of the contraindications were based on nonclinical data, such as teratogenicity and fetotoxicity data in reproductive toxicity studies involving pregnant animals and pharmacokinetic information in breast-feeding animals. The overall revision rate for the new instructions was 16.2% after three years of revision work for each drug. The alert wording has been revised to provide more clarity and consistency, with three categories of statements: “should not be administered/avoid breastfeeding,” “advisable not to administer/breastfeed,” and “should be administered/breastfeed in consideration of the therapeutic benefit (benefit-risk consideration).” The statement indicating that the drug should not be administered to pregnant women remained in the revised instructions. Conversely, the revision of the description for breast-feeding women from “should be discontinued/avoided” to “benefit-risk consideration” may have improved the usefulness of the product, allowing healthcare professionals to make more informed decisions after considering the transfer of the drug into milk, its pharmacological effects, and other factors.

A Method for Identifying Pregnant Women by Linking Mothers and Newborns in the JMDC Database and Its Generalizability Study / 薬剤疫学

Objective：To show that it is possible to capture pregnant women by identifying newborns and their mothers using JMDC database and examine a generalizability to Japan.Methods：We identified a newborn who was born between 2016 and 2020 and his/her mother using health insurance association's registry owned by JMDC Inc. First, we identified a newborn whose relationship to the insured was “child” and who joined the health insurance association at birth month. And we linked a woman member aged 18 to 49 who belongs to the same family at the newborn's birth month to the newborn as a mother. We assessed a generalizability of these mothers and newborns obtained from this method by an age distribution of mother at birth month and proportion of newborn against women aged between 18 and 49 using Vital Statistics, National Census, and Population Estimates in Japan as index.Results：We identified 194,036 mother-newborn pairs in JMDC database from 2016 to 2020. The mean mother's age at newborn's birth was 31.9. On the other hand, the number of births in Japan during the same period was 4,538,786, and the mean mothers' age was 31.5. Number of newborns per 1,000 women in JMDC database in 2020 was 19.0, and that in Japan was 37.0.Conclusion：We concluded that our method of identifying pregnant women and newborns is useful for study of pregnant women and newborns.

[Objective]To explore the clinical efficacy of modified Yupingfeng Powder combined with western medicine in the treatment of pregnant women with mild corona virus disease 2019(COVID-19).[Methods]The pregnant women with mild COVID-19 admitted to Shanghai Public Health Clinical Center from April 2022 to June 2022 were divided into treatment group and control group randomly.The control group(52 cases)was treated with western medicine such as Vitamin C,and the treatment group(48 cases)was treated with modified Yupingfeng Powder on the basis of control group.A comparison was made between the two groups in terms of each symptoms scores,incidence of adverse pregnancy outcomes and total effective rate.Besides,the levels of laboratory indicators involving lymphocyte,C reactive protein(CRP),interleukin-2 receptor(IL-2R)and interleukin-6(IL-6)were also be compared.The negative changes of virus nucleic acid and disease outcome were observed in the two groups.[Results]Compared with control group,after treatment cessation,the total symptom score in treatment group significantly decreased(P＜0.001),and the total effective rate significantly increased(P＜0.01).The levels of inflammatory markers including CRP and IL-6 decreased significantly in treatment group(P＜0.001,P＜0.01),while the count of lymphocyte increased significantly(P＜0.001).Besides,there was no difference in the incidence of adverse pregnancy outcomes between the two groups(P＞0.05).[Conclusion]Modified Yupingfeng Powder combined with western medicine can significantly relieve the clinical symptoms of pregnant women with mild COVID-19,while shortening nucleic acid negative conversion time and does not affect the pregnancy outcome,which has certain clinical value and is worthy of clinical application.

Clinical features of acute pancreatitis in pregnancy and related risk factors / 临床肝胆病杂志

ObjectiveTo investigate the clinical features and maternal and fetal outcomes of acute pancreatitis in pregnancy （APIP） and the risk factors for disease aggravation， and to establish a predictive model. MethodsA retrospective analysis was performed for 52 APIP patients who were admitted to Affiliated Hospital of Zunyi Medical University from January 2017 to December 2022， and according to disease severity， they were divided into mild acute pancreatitis （MAP） group with 32 patients， moderate-severe acute pancreatitis （MSAP） group with 8 patients， and severe acute pancreatitis （SAP） group with 12 patients. The logistic regression analysis was performed for the clinical data of each group，and the receiver operating characteristic （ROC） curves were plotted to assess the value of risk factors in predicting the severity of APIP. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups，and the least significant difference t-test was used for further comparision between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups，and the Wilcoxon rank-sum test was used for further comparision between two groups； the chi-square test was used for comparison of categorical data between groups. ResultsOf all patients in terms of etiology， 26 （50%） had hyperlipidemic pancreatitis， 20 （38.4%） had biliary pancreatitis， and 6 （11.5%） had idiopathic pancreatitis. In terms of gestational week， 1 patient （1.9%） was in early pregnancy， 25 （48.1%） were in mid-pregnancy， and 26 （50.0%） were in late pregnancy. A total of 10 patients （19.2%） had acute respiratory distress syndrome （ARDS）， among whom 9 （90%） required respiratory support. There were significant differences between the patients with different severities of APIP in aspartate aminotransferase， alanine aminotransferase， blood urea nitrogen， blood glucose， C-reactive protein （CRP）， international normalized ratio （INR）， pneumonia， ARDS， sepsis， hepatic insufficiency， and coagulation dysfunction （all P<0.05）. The univariate analysis showed that the severity of APIP was associated with blood glucose， blood urea nitrogen， CRP， and pneumonia （all P<0.05）， and pneumonia was a risk factor for the aggravation of APIP （odds ratio=18.938， 95% confidence interval： 1.020 ‍— ‍351.747， P=0.048）. CRP， blood glucose， blood urea nitrogen， and INR used in combination had a larger area under the ROC curve than each index used alone （0.954 vs 0.778/0.796/0.721/0.801）. ConclusionPneumonia is a risk factor for the aggravation of APIP， and the combination of CRP， blood glucose， blood urea nitrogen， and INR can be used to predict the severity of APIP.
