Tecnologias eHealth nos cuidados parentais aos bebês nascidos prematuros: revisão integrativa / EHealth technologies in parental care for preterm infants: an integrative review

Resumo As tecnologias eHealth contribuem na promoção das práticas parentais de cuidado para bebês pré-termo. Não obstante, é notável a abundância de informações e aplicativos disponíveis, a disparidade na qualidade, facilidade de uso e confiabilidade desses recursos. Este artigo objetiva examinar as tecnologias eHealth direcionadas aos pais para o cuidado de bebês pré-termo. Realizou-se uma revisão integrativa nas principais bases de dados da área da saúde (Capes, EBSCO, BVS, PubMed, Scholar e SciELO), com a seleção de publicações de 2011 a 2022, em português e inglês, sobre a utilização de tecnologias eHealth voltadas aos cuidados de bebês pré-termo. Identificaram-se 13 artigos com temáticas sobre: as tecnologias da informação e comunicação nas estratégias de educação e a promoção da saúde de bebês pré-termo e seus pais; e importância da avaliação e validação das tecnologias eHealth na promoção da saúde materno-infantil. Tecnologias eHealth validadas adequadamente podem desempenhar um papel fundamental em apoiar os pais na promoção da saúde e na prestação de cuidados ao bebê pré-termo após a alta hospitalar. Isso, por sua vez, tem o potencial de impulsionar a evolução dos sistemas de saúde e a melhoria das práticas clínicas.

Abstract The eHealth technologies promote parental care practices for preterm infants. Nonetheless, we should underscore the abundant information and available apps and disparities in these resources' quality, usability, and reliability. This article examines eHealth technologies directed at parents to care for preterm infants. An integrative review was conducted across the principal health databases (Capes, EBSCO, BVS, PubMed, Scholar, and SciELO), selecting works published from 2011 to 2022 in Portuguese and English, focusing on the use of eHealth technologies for the care of preterm infants. We identified 13 articles related to information and communication technologies in strategies for educating and promoting the health of preterm infants and their parents and the importance of evaluating and validating eHealth technologies in maternal and child health promotion. Properly validated eHealth technologies can be crucial in supporting parents in promoting health and providing care for preterm infants after hospital discharge, which, in turn, can drive the evolution of healthcare systems and improve clinical practices.

Red blood cell transfusions in preterm infants in 2021: a narrative review / Transfusão de células vermelhas em prematuros em 2021: uma revisão narrativa

Anemia is frequent in preterm infants. Red blood cell transfusion practices vary between different centers. The objective of this study was to review red blood cell transfusion practices in preterm infants between 2020 and 2021. This was a narrative review that included studies published on PubMed (Medline) and Web of Science between October 2020 and October 2021. Ten studies were included finally. Red blood cell transfusion frequency was variable. Some neonatal units did not report transfusion protocols. Most studies reported volumes of 10-15 ml/kg per transfusion. The implementation of an anemia care bundle and adoption of restrictive transfusion resulted in a reduction in the number of transfusions, the volume transfused, and a reduction in the rate of multiple transfusions. We suggest that neonatal units that care for preterm infants should have a transfusion protocol based on the best evidence available and this issue may improve.

A anemia é frequente nos bebês prematuros. As práticas de transfusão de glóbulos vermelhos variam entre os diferentes hospitais. O objetivo deste estudo foi revisar as práticas de transfusão de glóbulos vermelhos em bebês prematuros entre 2020 e 2021. Esta foi uma revisão narrativa que incluiu estudos publicados no PubMed (Medline) e Web of Science entre outubro de 2020 e outubro de 2021. Dez estudos foram definitivamente incluídos. A frequência de transfusão de glóbulos vermelhos foi variável. Algumas unidades neonatais não relataram protocolos de transfusão. A maioria dos estudos relatou volumes de 10-15 ml/kg por transfusão. A implantação de um conjunto de cuidados para anemia e a adoção de transfusão restritiva resultaram em uma redução do número de transfusões, do volume transfundido e uma redução na taxa de transfusões múltiplas. Sugerimos que as unidades neonatais que prestam cuidados a bebês prematuros devem ter um protocolo de transfusão baseado em evidências para que todo esse problema melhore.

Time trends of avoidable deaths in Brazil, 1996 to 2019

Introduction: The known achievements of the Brazilian Unified Health System (SUS) stand out in an adverse context. This makes it necessary to examine the effect of the SUS on the population's health, using indicators such as deaths by avoidable causes. Objective: To describe the time trends of mortality from avoidable causes in Brazil and to compare them to those of non-avoidable causes. Methods: Ecological time-series study with official mortality data, during years 1996-2019, in the age group 5-74 years. Time trends in mortality were estimated as the annual percent reduction in mortality rates, and the impact of the SUS was calculated as the difference in trend between avoidable (immunopreventable, infectious and noncommunicable diseases, maternal and external causes) and non-avoidable causes. The analyses consisted of multivariable binomial regression models, by quadrennium. Results: Death rates for each avoidability group remained stable or declined throughout the study period. The probability of a positive impact was greater than 90% for immunopreventable diseases throughout the study period; infectious diseases in 1996-2003 and 2016-2019; noncommunicable diseases in 1996-2003 and 2008-2019; maternal causes in 1996-1999; and external causes in 1996-2007. This probability was less than 10% for maternal deaths in 2016-2019; and external causes in 2008-2015. Conclusion: The SUS has had a positive impact in reducing deaths from immunopreventable, infectious and noncommunicable diseases in Brazil, although not so much for maternal and external causes.

Association of oropharyngeal colostrum administration with decreased inflammatory indices in premature newborns weighing less than 1500 g / Asociación de la administración de calostro orofaríngeo con la disminución de los índices inflamatorios en recién nacidos prematuros menor de 1500 g

Abstract Background: The administration of colostrum through its absorption at the oropharyngeal level stimulates the mucosa-associated lymphoid tissue, providing a local immunological protection barrier. The study aimed to investigate the association of oropharyngeal colostrum administration with the reduction of inflammatory indices. Materials and methods: This was an observational, ambispective, analytical study of newborns < 32 weeks of gestation at risk of sepsis. Oropharyngeal colostrum was administered at 0.2 mL every 4 h for 5 days. Inflammatory indices were analyzed. Statistical analysis included frequencies, percentages, mean and Standard deviation, contingency coefficient, and Kolmogorov–Smirnov test for the distribution curve of the numerical data. Results: There were 50 patients, 33 (66%) female and 17 (34%) male, with a median gestational age of 30-31 weeks (95% confidence interval [CI]). Nineteen patients had sepsis. A lower positivity rate in C-reactive protein was found, with a median of 0.5-0.6 (95% CI) at 5 days of colostrum administration versus 0.5-1.1 (95% CI) as the initial C-reactive protein. Analysis with χ2 yielded a p = 0.13, and the contingency coefficient showed a p = 0.196, indicating an association. Conclusion: Oropharyngeal colostrum administration was associated with a lower C-reactive protein positivity rate and clinical improvement in premature newborns at risk of sepsis.

Fisiopatología de la displasia broncopulmonar / Pathophysiology of bronchopulmonary dysplasia

La fisiopatología de la displasia broncopulmonar (DBP) se centra en la interrupción del desarrollo pulmonar durante etapas críticas en las que la histología, anatomía y función celular están en proceso de adaptación para facilitar el intercambio gaseoso eficiente. Este desarrollo, que avanza hacia la etapa alveolar después de la etapa sacular, ocurre simultáneamente con una respuesta inflamatoria y de reparación al daño. Como resultado, se afectan la vía aérea (principalmente a través de la limitación obstructiva), los alvéolos (resultando en hipoxemia) y la vasculatura pulmonar (provocando hipertensión pulmonar).

The pathophysiology of bronchopulmonary dysplasia (BPD) is centered on the disruption of lung development during critical stages where histology, anatomy, and cellular function are adapting to facilitate efficient gas exchange. This development, advancing towards the alveolar stage after the saccular stage, occurs concurrently with an inflammatory and damage repair response. As a result, it affects the airway (primarily through obstructive limitation), alveoli (resulting in hypoxemia), and pulmonary vasculature (leading to pulmonary hypertension).

Probability and trend of premature death of four major chronic diseases in Linyi City in 2013-2021 / 公共卫生与预防医学

Objective To analyze the mortality rate and probability of premature death caused by four major noninfectious chronic diseases (NCDs)in Linyi City from 2013 to 2021, and to provide data support for scientific formulation of chronic disease prevention and control strategy. Methods The mortality data of major chronic diseases in Linyi City from 2013 to 2021 were analyzed. The crude mortality, age-standardized mortality and premature death probability were calculated. The annual percent change (APC) was adopted to analyze the temporal trend of mortality and probability of premature death. Results The average annual crude mortality of four major NCDs was 538.98/100,000, and the age-standardized mortality was 387.3/100,000. The crude mortality rate increased from 517.37/100 000 in 2013 to 563.13/100 000 in 2021 (APC=0.89％, P=0.01). The age-standardized mortality rate decreased from 410.19/100,000 to 364.92/100,000 (APC=-1.8％, P=0.01). The crude mortality and age-standardized mortality of four major NCDs in males were higher than those in females (P<0.05). The average annual probability of premature death caused by four major NCDs was 13.37%. The probability of premature death decreased from 14.49％ in 2013 to 12.32％ in 2021（APC=-2.1％, P=0.00）. From 2013 to 2021, the probability of premature death from malignant tumors, cardiovascular and cerebrovascular diseases, and chronic respiratory diseases in Linyi City dropped from 6.14%, 7.47%, and 1.21% to 5.52%, 6.46%, and 0.5%, respectively (APCs were -1.2%, -2.1%, and -11.3%, respectively, and P values were 0.04, 0.00, and 0.00, respectively). The probability of premature death from diabetes remained stable. The probability of premature death caused by four major NCDs in males was higher than that in females (P<0.05). Conclusion The probability of premature death of the four major NCDs in Linyi has showed a downward trend during 2013-2021. It is suggested to strengthen the prevention and control of diabetes in the next step.

Mechanism of Cuscutae Semen to Control Premature Ovarian Failure Based on Lipid and Atherosclerosis Pathways / 中国实验方剂学杂志

ObjectiveThe active ingredients， action targets， and signaling pathways of Cuscutae Semen to control premature ovarian failure were initially predicted by network pharmacology and molecular docking techniques， and an animal model of premature ovarian failure was constructed to explore the mechanism of Cuscutae Semen based on lipid and atherosclerosis signaling pathways. MethodThe effective components and corresponding targets of drugs were obtained from Traditional Chinese Medicines Systems Pharmacology Platform （TCMSP）， Swiss Target Prediction， Pharmmapper， and other databases. GeneCards database was used to collect disease-related targets. Venny2.1.0 online tool was used to screen out the intersection targets of drugs and diseases， and STRING database and Cytoscape v3.7.2 software were used to construct the network diagram of "drug-component-target" and protein-protein interaction （PPI）. The gene ontology （GO） and the Kyoto encyclopedia of genes and genomes （KEGG） enrichment analyses of the intersection targets were performed by running the R language script. The molecular docking technology was utilized to dock drug components with targets and visualize some of the docking results. The mice were randomly divided into a blank group， a model group， a Cuscutae Semen group， and an estradiol valerate group， and the ovarian premature failure model was prepared by chronic stress. The blank group and the model group were gavaged with the same amount of normal saline， and the Cuscutae Semen group was given a Cuscutae Semen decoction of 2.6 g·kg-1·d-1. The estradiol valerate group was given an estradiol valerate solution of 0.13 mg·kg-1·d-1. After four weeks， samples were collected， and hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the ovary. Serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E2）， Muller's tube inhibitor/anti-Muller's tube hormone （AMH）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were determined by enzyme-linked immunosorbent assay （ELISA）. The expression levels of extracellular regulatory protein kinase （ERK）， nuclear transcription factor-κB p65 （NF-κB p65）， nuclear transcription factor-κB suppressor α （IκBα）， interleukin-1β （IL-1β）， IL-6， and tumor necrosis factor-α （TNF-α） were measured by Western blot. ResultA total of 171 targets of Cuscutae Semen for the prevention and treatment of premature ovarian failure were screened， mainly including tumor protein p53 （TP53）， protein kinase B1 （Akt1）， sarcoma （SRC）， tumor necrosis factor （TNF）， epidermal growth factor receptor （EGFR）， etc. KEGG pathway enrichment analysis predicts that Cuscutae Semen is mainly involved in lipid and atherosclerosis， TNF signaling pathway， and TP53 signaling pathway to control premature ovarian failure. The animal experiments show that compared with the premature ovarian failure model group， the Cuscutae Semen group can significantly upregulate AMH， E2， and HDL-C （P<0.05， P<0.01）， significantly downregulate LH， TC， and LDL-C （P<0.01）， greatly reduce IL-1β， IL-6， and TNF-α protein levels， as well as ERK， NF-κB p65， and their phosphorylation levels （P<0.01）. ConclusionCuscutae Semen can regulate hormone levels and improve ovarian function through a multi-component， multi-target， and multi-pathway approach， and the mechanism may be related to the regulation of lipid and atherosclerosis signaling pathways.

Objective:To explore the early predictive value of umbilical cord blood S100β protein and lactate combined with amplitude integrated electroencephalogram（aEEG）in small for gestational age（SGA）preterm infants with brain injury.Methods:One hundred and six cases of SGA preterm infants were enrolled in this study in Neonatology Department of Inner Mongolia People's Hospital from January 2019 to December 2021. Umbilical cord blood serum S100β protein and lactate at birth of All SGA preterm infants were tested，and aEEG was monitored at 6h and 72 h after birth，corrected gestational age of 32 weeks and 37 weeks. According to the diagnostic criteria of brain injury in preterm infants，SGA preterm infants were divided into brain injury group（45 cases）and non-brain injury group（61 cases），and compared the differences of S100β protein，lactate and the designated time aEEG between the two groups.SGA preterm infants with brain injury were further divided into symmetrical group（28 cases）and non-symmetrical group（15 cases）. The differences of umbilical cord blood S100β protein and lactate level between the two groups were compared，and the diagnostic value in different types of SGA preterm infants with brain injury was also compared.Results:SGA preterm infants in the brain injury group had significantly higher levels of umbilical cord blood S100β protein［（0.826±0.218）μg/L vs（0.397±0.196）μg/L， t=8.316， P<0.05］and lactate［（8.5±1.3）mmol/L vs（3.8±0.9）mmol/L， t=3.281， P<0.05］than those in non-brain injury group.Symmetric SGA group had higher level of S100β protein than the asymmetric SGA group［（0.924±0.205）μg/L vs（0.438±0.196）μg/L， t=5.734， P<0.05］.But there was no statistically significant difference in lactate levels［（5.6±1.4）mmol/L vs（3.9±1.2）mmol/L， t=0.932， P>0.05］between symmetric SGA group and asymmetric SGA group. The abnormal rates of aEEG in brain injury group and non-brain injury group were respectively 100%（45/45）vs 22.95%（14/61）at 6 h after birth，95.56%（43/45）vs 16.39%（10/61）at 72 h after birth，62.22%（28/45）vs 6.56%（4/61）at 32 weeks of corrected gestational age，22.22%（10/45）vs 3.28%（2/61）at 37 weeks of corrected gestational age. The abnormal rate of brain injury group was higher than the non-brain injury group in the same nodal time，and the differences were statistically significant（ χ 2 value respectively 62.292，64.913，38.074，9.257，all P<0.05）. Conclusion:There were significant value in umbilical cord blood S100β protein，lactate level and aEEG monitoring in the early diagnosis in preterm infants SGA with brain injury. The combination of the three might be more helpful for the early diagnosis and timely treatment of brain injury in SGA preterm infants.

Discussion on the relationship between irritable bowel syndrome and premature ejaculation from 5-HT and prediction of natural drugs / 国际中医中药杂志

Objective:To explore the relationship between irritable bowel syndrome (IBS) and premature ejaculation (PE) from 5-HT; To predict the natural drugs with therapeutic effect.Methods:Targets related to IBS and PE were screened in the GeneCards, DisGeNET, TTD, OMIM, DrugBank databases. After removing duplicates, the two disease targets were intersected and imported into STRING platform, and the protein interaction network between IBS and PE targets related to 5-HT receptor was obtained. GO enrichment analysis was carried out on the intersected targets by R language, and Coremine Medical platform was used for predicting natural drugs.Results:5-HT1A, 5-HT1B, 5-HT2A, 5-HT2C and 5-HT3A were the common targets related to 5-HT in IBS and PE. GO function enrichment yielded 250 gene function related information, mainly enriched in serotonin receptor signaling pathways, cell response to dopamine, and response to dopamine. The prediction of natural drugs obtained 14 kinds of Chinese materia medica, including Nelumbinis Semen, Nelumbinis Rhizomatis Nodus, Nelumbinis Receptaculum, Nelumbinis Stamen, Nelumbinis Folium, Nelumbinis Plumula, Ginkgo Semen, and Ginkgo Folium.Conclusions:Abnormal 5-HT levels can affect gastrointestinal motility, ejaculation latency, and glans sensitivity. Elevated central 5-HT levels are a common pathogenesis of IBS and PE. The interaction between receptors such as 5-HT1A and 5-HT3A and 5-HT can regulate gastrointestinal motility and secretion activities, intestinal nervous system, and reduce intestinal hypersensitivity; increasing the sensitivity of the 5-HT1A receptor can reduce the ejaculation threshold and promote ejaculation, while increasing the sensitivity of the 5-HT2C receptor can increase the ejaculation threshold.

Theoretical Validation of the Identification of Therapeutic Dominant Stages of Traditional Chinese Medicine Based on Subdivision Model of Disease Course:Taking Premature Ovarian Failure for Example / 广州中医药大学学报

Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P＜0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P＜0.001),so did in the POF stage(r = 0.432,P＜0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.

Objective To observe the therapeutic effects and mechanisms of Guanyuan Mingmen Sequential Acupuncture on rats with premature ovarian insufficiency(POI)model.Methods Female SD rats were divided into the blank group,the model group,the protein kinase A(PKA)inhibitor(H89)+acupuncture group,and the acupuncture group,with 12 rats in each group.Except for the blank group,the POI model was prepared by gavage with Tripterygium Glycosides Tablets in the other three groups of rats.After the model was successfully established,the blank group and the model group were bundled once a day;in the acupuncture group,Guanyuan(RN4)point was taken during the intermotility period,and in the pre-motility period,Mingmen(DU4)point was taken;in the H89+acupuncture group,the intervention was performed in accordance with the acupuncture protocol of the acupuncture group,and H89 was injected intraperitoneally for 30 minutes prior to each acupuncture session.Continuous intervention was performed for 20 days.Samples were taken from each group of rats in the first estrus period and in proestrus period after intervention.Enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of follicle stimulating hormone(FSH)and estradiol(E2)during the estrous phase,Western Blot was used to measure the protein expressions of follicle stimulating hormone receptor(FSHR)and aromatase P450(P450arom)during the estrous phase,and the activity of granulocytes during the estrous phase and the proestrus phase were measured using the cell-counting kit 8(CCK-8)method.The immunohistochemistry method was used to detect the protein expression of pre-motility proliferating cell nuclear antigen(PCNA).Results(1)Compared with the blank group,the serum FSH level of the model group and H89+acupuncture group was significantly increased(P＜0.01),and the E2 level was significantly decreased(P＜0.001);there was no difference between the FSH level of the H89+acupuncture group and that of the model group(P＞0.05),and the E2 level of the H89+acupuncture group was lower than that of the model group(P＜0.05);the FSH level of the acupuncture group was lower than that of the model group and that of the H89+acupuncture group(P＜0.05),had no difference with the blank group(P＞0.05),E2 level was significantly higher than the model group and H89+ acupuncture group(P＜0.01),still being lower than the blank group(P＜0.05).(2)The protein expressions of FSHR and P450arom in the model group and H89 + acupuncture group was lower than those in the blank group;the protein expression of FSHR in the H89 + acupuncture group was not different from that in the model group(P＞0.05),while the protein expression level of P450arom was lower than that in the model group(P＜0.05);the protein expression levels of FSHR and P450arom in the acupuncture group were higher than those in the model group and H89 + acupuncture group,but still lower than those in the blank group(P＜0.05).(3)Both GCs activity and average optical density value of PCNA in the model group and H89+acupuncture group were lower than the blank group(P＜0.05);both GCs activity and average optical density value of PCNA in the H89+acupuncture group were lower than the model group(P＜0.05);the activity of GCs and average optical density value of PCNA of the acupuncture group were significantly higher than that of the model group and H89+acupuncture group(P＜0.05 or P＜0.01).Conclusion Guanyuan Mingmen Sequential Acupuncture can regulate sex hormone levels,increase GCs activity and promote GCs cell proliferation by up-regulating protein expressions of follicle stimulating hormone receptor(FSHR)/cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)pathway FSHR,P450arom,thus improving POI.

Chinese Medicines Combined with Hormones in the Treatment of Premature Ovarian Failure:A Network Meta-analysis / 广州中医药大学学报

Objective To screen the optimal regimen of Chinese medicine combined with hormones for the treatment of premature ovarian failure(POF)using network meta-analysis and to provide an evidence-based basis for the clinical treatment of POF.Methods The randomized controlled trials(RCTs)of Chinese medicine combined with hormones in the treatment of POF were retrieved from thhe domestic and oversea databases of CNKI,VIP,Wanfang,CBM,PubMed,Cochrane,Embase,and Web of Science.The quality of the literature was assessed using the tools for analysis of bias recommended by Cochrane Reviewer's Handbook and by Jadad scale scores.Rstudio and StataSE 15.1 statistical software were used to perform network meta-analysis and graphical presentation of the data.Results A total of 50 RCTs were included,covering 8 intervention methods.The overall risk of bias of the included studies was low,but the quality of the literature was generally low.The results of network meta-analysis showed that,in terms of the effective rate,the intervetion of 7 various Chinese medicines combined with hormone was superior to the conventional treatment(hormone replacement therapy,HRT)in the control group,and Nuangong Qiwei Powder+HRT was superior to the remaining 6 kinds of Chinese medicines combined with HRT;with reference to the values of the surface under the cumulative ranking curve(SUCRA),the efficiencies of the effective rate of the 8 intervention methods in descending order were Nuangong Qiwei Powder+ HRT(SUCRA=81.2),Zishen Yutai Pills + HRT(SUCRA=80.0),modified Zuogui Pills + HRT(SUCRA= 66.1),Ankun Zhongzi Pills + HRT(SUCRA=49.6),Kuntai Capsules + HRT(SUCRA=45.2),modified Erxian Decoction + HRT(SUCRA=39.5),Liuwei Dihuang Pills + HRT(SUCRA=37.4)and HRT(SUCRA=1.0).In terms of improving serum follicle-stimulating hormone(FSH)levels,modified Zuogui Pills + HRT was superior to the remaining 7 intervention methods;with reference to the values of the SUCRA,the efficiencies of the 8 intervention methods in descending order were modified Zuogui Pills + HRT(SUCRA=97.0),HRT(SUCRA= 77.9),Liuwei Dihuang Pills + HRT(SUCRA=76.6),Kuntai Capsules + HRT(SUCRA=46.5),Nuangong Qiwei Powder+HRT(SUCRA=38.9),Ankun Zhongzi Pills + HRT(SUCRA=29.9),modified Erxian Decoction + HRT(SUCRA=18.1),and Zishen Yutai Pills + HRT(SUCRA=15.1).Conclusion All kinds of Chinese medicines combined with HRT exert stronger effect on improving the primary outcome indicators than HRT alone for the treatment of POF.The intervention with Nuangong Qiwei Powder+HRT exerts the highest probability of the optimal regimen for enhancing the efficiency,and the intervention with Zuogui Pills + HRT exerts the highest probability of the optimal regimen for lowering the serum FSH level.However,due to the low quality of the included studies,more rigorously-designed,large sample-size,and high-quality randomized controlled trials need to be conducted in the future to provide conclusive evidence-based evidence.

Screening threshold for congenital adrenal hyperplasia in preterm and full-term infants by an indirect method / 中华实用儿科临床杂志

Objective:To analyze the difference and reliability of blood 17-hydroxyprogesterone (17-OHP), an indirect screening index for congenital adrenal hyperplasia (CAH), between preterm and full-term infants.Methods:In this retrospective cross-sectional study, a total of 210 285 newborns who underwent CAH screening at the Neonatal Screening Center of Shanghai Children′s Hospital from January 2019 to December 2022 were collected, including 14 312 premature infants and 195 973 full-term infants.The concentration of 17-OHP in dried blood spots on filter paper was determined by an automatic fluorescence analyzer.The distribution of 17-OHP levels in preterm and full-term infants and its statistical index were analyzed.The Kolmogorov-Smirnov test was used for normal distribution.The skewed distribution data was converted into approximately normal distribution using Box-Cox.Outliers were eliminated by the interquartile range method.The cumulative frequency distribution map was drawn by R language programming.The 99.5 th percentile value was used as the screening threshold and compared with the reference value given by the manufacturer or laboratory and with the reference change value (RCV). Results:According to the threshold provided by the laboratory, 26.76‰ of premature infants were tested positive in preliminary screening, and 4 were confirmed with an incidence of 1∶3 578, while 0.79‰ of full-term infants were tested positive in preliminary screening, and 11 were confirmed with an incidence of 1∶17 816.The thresholds for CAH screening established indirectly were 20.35 nmol/L in preterm infants and 10.78 nmol/L in full-term infants.The relative deviations between the indirect CAH screening thresholds and the manufacturer′s or laboratory′s CAH screening thresholds were higher than the RCV, respectively.According to the indirect CAH screening thresholds, the negative and positive coincidence rates of 65 samples in 13 batches from the Centers for Disease Control and Prevention interlaboratory quality assessment program in the United States reached 100%.A retrospective analysis of 210 285 neonates showed that 17-OHP concentration was higher than the screening threshold in all CAH-positive neonates.The application of this screening threshold reduced the false positive rate of preterm infants by 59.79%.Conclusions:It is feasible to establish the CAH screening thresholds for premature and full-term infants by an indirect method, which can improve the efficiency of screening and provide better diagnostic basis for clinical practice.

Establishment and verification of a predictive model for feeding intolerance in premature infants / 中国实用护理杂志

Objective:The prediction model of feeding intolerance in preterm infants was established and validated to provide guidance for clinical practice.Methods:This was a case-control study. A retrospective analysis was conducted on 210 premature infants with gestational age less than 34 weeks from September 2022 to May 2023. They were divided into training and validation sets in a 1∶1 ratio. The univariate and multivariate binary Logistic regression analysis were performed on training set samples, first identified the risk factors for feeding intolerance occurrence, and established a premature feeding intolerance risk prediction model based on these risk factors. Visualized the model using a column chart. The performance of the model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and clinical decision curves in the training and validation sets, respectively. The ROC curve was used to evaluate the differentiation ability of the model, the calibration curve was used to evaluate the consistency of the model, and clinical decision-making was used to evaluate the net benefit status of patients when the model guides clinical interventions.Results:Among them, there were 84 cases in the feeding tolerance and 126 cases in the feeding intolerance. There were 53 males and 31 females with feeding tolerance aged (32.38 ± 1.37) weeks and 73 males and 53 females with feeding intolerance aged (30.01 ± 2.14) weeks. Through univariate Logistic regression analysis of 12 related variables, there were significant differences between the feeding tolerance premature infants and the feeding intolerance premature infants in 8 variables of premature birth weight, birth asphyxia, caffeine use, delayed defecation, gestational age, lactation time, non-invasive ventilation time, and invasive ventilation time ( OR values were 0.032-18.706, all P<0.05). Multiple Logistic regression ultimately screened out three variables, namely premature infant body mass, delayed defecation, and non-invasive ventilation time ( OR = 0.073, 4.926, 1.244, all P<0.05). The area under the ROC curve of the training and validation sets were 0.906 and 0.876, respectively. The calibration curves of the training and validation sets indicated that the model had high consistency. The Hosmer-Lemeshow goodness of fit test showed that χ2 = 7.92, P = 0.442. Conclusions:The prediction model established in this study has high discrimination, calibration, and clinical practical value, and can accurately predict the risk of feeding intolerance in premature infants, providing reference basis for timely nursing and clinical intervention.
