Methodology: This was a mixed prospective qualitative and quantitative study conducted over a 2-year period, from January 1, 2022, to December 31, 2023. This study took place in Senegal, a country with limited resources and a weakness of hyperspecialized medical technical resources. There was no policy for the management of fetal malformations. The qualitative part was carried out through overt participant observation. The human resources and the organization of the perinatal network were described. For the quantitative part, all fetuses managed during the study period were included. The studied parameters related to neonatal care and outcomes. Qualitative variables were described using dispersion parameters, and quantitative variables were described using proportions. Results: The perinatal network includes several specialists across six hospitals. Of these hospitals, only one provided emergency pediatric surgery. The network included highly specialized human resources in prenatal diagnosis, congenital heart defects, pediatric surgery, anesthesia, and other medical specialties in perinatology. Advanced ultrasound was centralized by an obstetrician. The team decided on the follow-up methods, timing, and mode of delivery. The newborn was immediately transferred to the appropriate specialty. Over the 2-year period, 201 fetuses were managed. The rate of cesarean delivery was 76.3%. Neonatal mortality was 51.4%. Discussion: Centralizing care improves the quality of prenatal diagnosis and management of congenital defects. Mortality remains high when emergency surgery is not well available. This mortality is also due to the lack of a single center offering all perinatal care and so, the transfer of newborns. The cesarean rate increases due to underlying conditions and organizational factors. Conclusion: Public policies should prioritize the centralization of care for congenital disorders to reduce the costs of disability and mortality.展开更多

Its impact on maternal and fetal health places pregnant women at high risk. The aim of our study was to determine the factors associated with the occurrence of COVID-19 in pregnant women, and the maternal and perinatal outcomes of infected patients. Methodology: This was a case-control study involving 42 cases matched to 42 controls recruited from two public and tertiary hospitals in the cities of Yaoundé and Douala over a period from November 31 to May 31, 2024. Cases were defined as deliveries or records of COVID-19 deliveries confirmed positive by reverse transcription polymerase chain reaction (RT-PCR) or by a COVID-19 rapid diagnostic test (Covid-RDT). Controls were defined as deliveries or records of deliveries negative to the same test. They were matched by the hospital. Non-consenting births and unusable records were excluded. The data collected were recorded on a pre-established, pretexted data sheet examining sociodemographic, clinical characteristics and maternal and perinatal outcomes which were then analyzed using SPSS version 23.0 software. Results: After multivariate analysis, the independent sociodemographic factors were: belonging to the [30 - 40] age group (OR: 4.4;P = 0.010), being married (OR: 8.1;P = 0.030);being unemployed (OR: 3;P = 0.040). Independent clinical factors were: being in the third trimester of pregnancy (OR: 1.1;P = 0.017), being diabetic (OR: 5;P = 0.033) and being obese (OR: 11.5;P = 0.043). Independent factors associated with maternal outcome were: caesarean section (OR: 10;P = 0.001);admission to intensive care (OR: 30.7;P = 0.013);SO2 ≤ 94% (OR: 11.7;P = 0.033);HR > 100 (OR: 15.5;P = 0.001). Independent factors associated with perinatal outcome were: weight Conclusion: The factors associated with the occurrence of COVID-19 in pregnant women are multiple, and maternal outcome depends on its condition on admission, and has a significant impact on perinatal health, including mode of delivery. Emphasis must be placed on prevention and optimal management of these associated factors.展开更多

In humans and labor atory animals, the plasticity of metabolic function in foetuses or neonates enab les them to adapt to malnutrition for survival; however, such an adaptation, as usually evidenced by retarded growth, stunted development of lymphoid organs and impaired immunocompetence, can maintain and persist into later life even when n utrition is improved. Early nutrition may thus programme' the immune system of a nimals. Limited experimental studies have also revealed that long-term immunity against nematode parasites in sheep can be enhanced by a short-term protein su pplementation shortly after weaning, a form of 'nutritional programming', but su ch an effect appears to vanish if the nutritional status of young animals alread y meets at least the requirement for maintenance.展开更多

The role of stem cells in this context is under intense scrutiny and may help to define principles of organ regeneration and develop innovative therapeutics for organ failure. Utilizing stem and progenitor cells for organ replacement has been conducted for many years when performing hematopoietic stem cell transplantation. Since the first successful transplantation of umbilical cord blood to treat hematological malignancies, non-hematopoietic stem and progenitor cell populations have recently been identified within umbilical cord blood and other perinatal and fetal tissues. A cell population entitled mesenchymal stromal cells (MSCs) emerged as one of the most intensely studied as it subsumes a variety of capacities: MSCs can differentiate into various subtypes of the mesodermal lineage, they secrete a large array of trophic factors suitable of recruiting endogenous repair processes and they are immunomodulatory.Focusing on perinatal tissues to isolate MSCs, we will discuss some of the challenges associated with these cell types concentrating on concepts of isolation and expansion, the comparison with cells derived from other tissue sources, regarding phenotype and differentiation capacity and finally their therapeutic potential.展开更多

文摘BACKGROUND Paternal perinatal depression(PPD)is closely associated with maternal mental health challenges,marital strain,and adverse child developmental outcomes.Despite its significant impact,PPD remains under-recognized in family-centered clinical practice.Concurrently,against the backdrop of rising rates of delayed marriage and China’s Maternity Incentive Policy,the proportion of women giving birth at an advanced maternal age is increasing.Nevertheless,research specifically examining PPD among spouses of older mothers remains critically scarce,both in China and globally.AIM To investigate PPD and its influencing factors in Chinese advanced maternal age families.METHODS This cross-sectional study included 358 participants;it was conducted among fathers of pregnant women of advanced maternal age at five hospitals in the Pearl River Delta region of China from September 2023 to June 2024.Data were collected via a general information questionnaire,the Social Support Rating Scale,and the Edinburgh Postnatal Depression Scale.Latent profile analysis and regression mixture models(RMMs)were adopted to analyze the latent PPD types and factors that influenced PPD.RESULTS The incidence of PPD was 16.48%,and three profiles were identified:Low-symptomatic(175 cases,48.89%),monophasic(140 cases,39.10%),and high-symptomatic(43 cases,12.01%).The RMM analysis revealed that first pregnancy,low income(<¥3000/month),part-time work,and a history of abnormal pregnancy were positively associated with the high-symptomatic type(P<0.05).Conversely,high subjective support and support utilization were negatively associated with the high-symptomatic type compared with the low-symptomatic type(P<0.05).Good couple relationships,high objective and subjective support,and high support utilization were negatively associated with monophasic disorder(P<0.05).CONCLUSION PPD incidence is high among Chinese fathers with advanced maternal age partners,and the characteristics of depression are varied.Healthcare practitioners should prioritize individuals with low levels of social support.

文摘Preterm birth and suboptimal fetal growth remain significant perinatal challenges worldwide.Recent data indicate that China's perinatal profile has improved due to reductions in preterm birth rates.However,the country has a 6.5%prevalence of small-for-gestational-age(SGA),ranking fifth globally in total SGA birth numbers^([1,2]).
文摘Objective: To evaluate the organizational model of a perinatal network and its relevance in a resource-limited country. Methodology: This was a mixed prospective qualitative and quantitative study conducted over a 2-year period, from January 1, 2022, to December 31, 2023. This study took place in Senegal, a country with limited resources and a weakness of hyperspecialized medical technical resources. There was no policy for the management of fetal malformations. The qualitative part was carried out through overt participant observation. The human resources and the organization of the perinatal network were described. For the quantitative part, all fetuses managed during the study period were included. The studied parameters related to neonatal care and outcomes. Qualitative variables were described using dispersion parameters, and quantitative variables were described using proportions. Results: The perinatal network includes several specialists across six hospitals. Of these hospitals, only one provided emergency pediatric surgery. The network included highly specialized human resources in prenatal diagnosis, congenital heart defects, pediatric surgery, anesthesia, and other medical specialties in perinatology. Advanced ultrasound was centralized by an obstetrician. The team decided on the follow-up methods, timing, and mode of delivery. The newborn was immediately transferred to the appropriate specialty. Over the 2-year period, 201 fetuses were managed. The rate of cesarean delivery was 76.3%. Neonatal mortality was 51.4%. Discussion: Centralizing care improves the quality of prenatal diagnosis and management of congenital defects. Mortality remains high when emergency surgery is not well available. This mortality is also due to the lack of a single center offering all perinatal care and so, the transfer of newborns. The cesarean rate increases due to underlying conditions and organizational factors. Conclusion: Public policies should prioritize the centralization of care for congenital disorders to reduce the costs of disability and mortality.

文摘The purpose of this experiment was to investigate the effect and mechanism of quercetin on reproductive performance in perinatal sows.According to the similar principle of parity and body weight,24 perinatal sows were randomly divided into four treatments with six replicates,including normal control and three treatments fed by a basal diet supplemented with 0,0.025%,0.050%,and 0.075%quercetin,respectively.The feeding trial was conducted from 100 days of gestation to 28 days post-partum.Reproductive performance,colostrum composition,serum indexes of antioxidation,inflammation,hormones,and the diversity and relative abundance of fecal microflora were determined in perinatal sows.Compared with the control,quercetin significantly reduced the rate of constipation,serum content of malondialdehyde(MDA),prolactin(PRL),and progesterone(PROG),and significantly increased the content of serum estradiol(E2)and insulin-like growth factor-1(IGF-1)in colostrum of perinatal sows(P<0.05).Meanwhile,0.025%quercetin significantly increased glutathione(GSH)content in serum(P<0.05),0.050%quercetin significantly reduced the rate of backfat loss(P<0.05),and 0.075%quercetin significantly increased immunoglobulin M(IgM)content in colostrum of perinatal sows(P<0.05).In addition,0.050%and 0.075%quercetin significantly shortened estrus interval(P<0.05)and significantly increased the content of IgA and IgG in colostrum(P<0.05)and dopamine(DA)content in serum of perinatal sows(P<0.05).Quercetin significantly decreased the content of nitric oxide(NO),IL-1β,IL-6,TNF-α,and MCP-1 in serum(P<0.05)and significantly improved microflora abundance and diversity in feces of perinatal sows(P<0.05).In conclusion,dietary supplementation of quercetin reduced oxidative stress and inflammatory responses and regulated intestinal microflora in perinatal sows,thus improved reproductive performance in perinatal sows.Under this experimental condition,the optimal supplementation with dietary quercetin was 0.075%in perinatal sows.
文摘Introduction: The Coronavirus pandemic was responsible for an unprecedented health crisis that shook the world with its high contagiousness and lethality. Its impact on maternal and fetal health places pregnant women at high risk. The aim of our study was to determine the factors associated with the occurrence of COVID-19 in pregnant women, and the maternal and perinatal outcomes of infected patients. Methodology: This was a case-control study involving 42 cases matched to 42 controls recruited from two public and tertiary hospitals in the cities of Yaoundé and Douala over a period from November 31 to May 31, 2024. Cases were defined as deliveries or records of COVID-19 deliveries confirmed positive by reverse transcription polymerase chain reaction (RT-PCR) or by a COVID-19 rapid diagnostic test (Covid-RDT). Controls were defined as deliveries or records of deliveries negative to the same test. They were matched by the hospital. Non-consenting births and unusable records were excluded. The data collected were recorded on a pre-established, pretexted data sheet examining sociodemographic, clinical characteristics and maternal and perinatal outcomes which were then analyzed using SPSS version 23.0 software. Results: After multivariate analysis, the independent sociodemographic factors were: belonging to the [30 - 40] age group (OR: 4.4;P = 0.010), being married (OR: 8.1;P = 0.030);being unemployed (OR: 3;P = 0.040). Independent clinical factors were: being in the third trimester of pregnancy (OR: 1.1;P = 0.017), being diabetic (OR: 5;P = 0.033) and being obese (OR: 11.5;P = 0.043). Independent factors associated with maternal outcome were: caesarean section (OR: 10;P = 0.001);admission to intensive care (OR: 30.7;P = 0.013);SO2 ≤ 94% (OR: 11.7;P = 0.033);HR > 100 (OR: 15.5;P = 0.001). Independent factors associated with perinatal outcome were: weight Conclusion: The factors associated with the occurrence of COVID-19 in pregnant women are multiple, and maternal outcome depends on its condition on admission, and has a significant impact on perinatal health, including mode of delivery. Emphasis must be placed on prevention and optimal management of these associated factors.

文摘BACKGROUND Pharmacological treatments are commonly used in individuals experiencing perinatal depression(PPD);however,a debate regarding the reproductive safety of antidepressants is ongoing.Many pregnant women opt to discontinue antidepressant out of concern about potential negative effects on the developing fetus,while slow and ineffective antidepressant medications hinder improved outcomes in women with PPD.In recent years,bright light therapy(BLT)has gained traction as a treatment option for PPD;however,clinical trials findings examining the efficacy of BLT in this population have been inconclusive.AIM To validate the feasibility and safety of BLT for the treatment of PPD.METHODS We performed a meta-analysis of randomized controlled trials of patients with PPD treated with BLT vs placebo following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis.We searched PubMed,Embase,the Cochrane Library,and Web of Science for randomized controlled studies published up to December 2023.The results were evaluated using the standardized mean difference of improvement for depression scores and odds ratios(ORs)for remission rate,response rate,incidence of adverse events,and dropout rate.RESULTS The BLT group had higher PPD response rate[50.68%vs 33.08%;OR=2.05;95% confidence interval(CI):1.25-3.35;P=0.004;I^(2)=35%]and remission rate(54.10%vs 18.52%;OR=5.00;95%CI:2.09-11.99;P=0.0003;I^(2)=0%)than the placebo group.Improvements in depression scores were higher in the BLT group than the placebo group for the overall efficacy(standardized mean difference=-0.47;95%CI:-0.80 to-0.13;P=0.007).No significant differences between the two groups in drop-outs(21.84%vs 29.63%;OR=0.63;95%CI:0.31-1.29;P=0.21;I^(2)=0%)or adverse events(17.89%vs 9.68%;OR=2.01;95%CI:0.95-4.25;P=0.07;I^(2)=0%)were observed.CONCLUSION BLT can potentially treat PPD,showing better results than the control group in this study.BLT is effective and safe and could increase the available therapeutic options for PPD.

文摘BACKGROUND Gestational diabetes mellitus(GDM)is one of the most prevalent metabolic disorders of pregnancy.Advanced glycation end-products(AGEs)are a complex and highly heterogeneous group of compounds formed from amino acids and reducing sugars.High-AGE diet exposure during pregnancy may cause adverse effects.AIM To investigate the expression levels of AGE and AGE receptor(RAGE)in the serum and placenta of pregnant women with GDM and to assess the association of their mediated oxidative stress response with perinatal outcomes.METHODS This study retrospectively analyzed the clinical data of 126 pregnant women with GDM who gave birth in the Obstetrics Department of Obstetrics and Gynecology Hospital of Fudan University from January 2023 to January 2024.A total of 85 pregnant women of similar age without GDM during the same period were selected as the control group.Fasting blood glucose,glycated hemoglobin,AGEs,soluble RAGE(sRAGE),and oxidative stress were compared in both groups.Postpartum placental tissue was collected to identify RAGE protein expression.Participants with GDM were categorized based on perinatal outcomes into normal(n=89)and adverse perinatal outcome groups(n=37),and differences in serum AGE–RAGE levels and oxidative stress were analyzed.The influencing factors of adverse perinatal outcomes were analyzed using logistic regression.RESULTS The GDM group demonstrated notably higher serum AGE(t=8.955)and malondialdehyde(MDA)levels(t=14.14)and lower sRAGE(t=16.37)and superoxide dismutase(SOD)levels(t=18.50)than the control group at 24-28 weeks of gestation and before delivery(P<0.0001).Serum AGE levels were positively correlated with MDA and negatively related to SOD at 24-28 weeks of pregnancy(SOD:r=0.393,MDA:r=0.424,P<0.0001)and before delivery(SOD:r=0.443,MDA:r=0.492,P<0.0001),whereas AGE was inversely associated with sRAGE in the GDM group(r=-0.495,P<0.0001).Serum AGE levels were significantly higher(t=9.225,P<0.0001)and the sRAGE level(r=3.563,P<0.0001)was significantly lower in participants with adverse perinatal outcomes than those with normal perinatal outcomes in the GDM group.Logistic regression analysis revealed AGE level as a risk factor(OR=1.056,P<0.0001)and sRAGE level(OR=0.949,P<0.0001)as a protective factor for adverse perinatal outcomes in GDM.CONCLUSION High serum AGE level is a risk factor for adverse perinatal outcomes in GDM,whereas high sRAGE levels are protective.AGEs and RAGE may be associated with oxidative stress in pregnant women with GDM.

文摘Background Relative energy deficiency in sport(REDs)results from exposure to problematic low energy availability.It is a serious condition affecting the health and athletic performance of up to 80%of elite female athletes.REDs is established to have negative short-term effects on reproductive function,but the long-term impact of this condition is unknown.Therefore,we examined the impact of secondary amenorrhea with or without a concurrent diagnosis of REDs on perinatal health outcomes.Methods Postpartum individuals(≥18 years of age)completed an online questionnaire that covered demographics,reproductive history(including a diagnosis of REDs or secondary amenorrhea),and maternal/fetal health outcomes.Logistic regression was used to determine the relationship between previously diagnosed REDs or secondary amenorrhea with perinatal health outcomes.Results A total of 1025 previously pregnant participants completed the survey(33.1±3.4 years,mean±SD).Prior to pregnancy,6.1%had been previously diagnosed with REDs and 20.5%had a history with secondary amenorrhea.Individuals diagnosed with REDs had 3.5-times higher odds of having premature labor(odds ratio,(OR)=3.52,95%confidence interval(95%CI):1.26–9.81)and 2.6-times higher odds of preterm delivery(OR=2.62,95%CI:1.05–6.58)compared to those who had not experienced REDs or secondary amenorrhea.However,in individuals who did not have a history of REDs,secondary amenorrhea did not increase the odds of adverse pregnancy or delivery outcomes.Conclusion A history of REDs,but not secondary amenorrhea,may increase the odds of premature labor and preterm delivery.
文摘BACKGROUND Perinatal depression affects 10%-20%of pregnant women and subsequently influences maternal health and fetal development.Concerns over the safety of antidepressants during pregnancy have prompted the exploration of nutritional interventions as adjunct therapies.This study evaluated the impact of combining preconception and prenatal supplementation with myo-inositol,probiotics,and trace elements on mood,quality of life,and fetal development in depressed mothers.This retrospective cohort study included 314 pregnant women who were diag-nosed with mild to moderate depression,as determined by a Zung self-rating depression scale score of less than 69.The participants were divided into an intervention group(n=161)receiving myo-inositol,probiotics,and trace elements and a control group(n=153)without supplementation.Supplementation comm-enced 3 months before conception and continued through pregnancy.Psychiatric symptoms and quality of life were evaluated using the positive and negative affect schedule-now,state-trait anxiety inventory,Patient Health Ques-tionnaire-8,and World Health Organization Quality of life Assessment:Brief Version scales preconception and postpartum.Fetal development metrics were assessed via ultrasound,and neonatal outcomes were recorded.RESULTS The intervention group presented significant reductions in gestational diabetes mellitus(13.04%vs 23.53%,P=0.016)and gestational hypertension(3.73%vs 9.15%,P=0.049).Higher levels of inositol,iron,zinc,and probiotics were observed near term in the intervention group.Postpartum mood assessments indicated lower anxiety and depression scores for the intervention group,with significant improvements in the positive and negative affect schedule-now(P=0.002),trait anxiety(P=0.002),and Patient Health Questionnaire-8(P=0.018)scores.The World Health Organization Quality of life Assessment:Brief Version scores improved in the psychological(P=0.041)and environmental(P=0.009)domains postpartum.Fetal biparietal diameter and femoral length were greater in the intervention group alongside better neonatal body length and reduced neonatal unit admissions(2.48%vs 7.84%,P=0.031).CONCLUSION Combined supplementation with myo-inositol,probiotics,and trace elements from preconception through pregnancy may reduce pregnancy-related complications,enhance mood and quality of life,and improve fetal growth metrics.
文摘BACKGROUND Perinatal anxiety disorder is the main problem affecting mother-infant bonding.Though the impact of perinatal anxiety in primiparous women on the motherinfant relationship is well established,appropriate interventions need to be explored.AIM To explore the synergistic intervention effect of mindfulness-based stress reduction combined with cognitive behavioral therapy(CBT)on perinatal anxiety disorders and mother-infant bonding in primiparas.METHODS A total of 150 primiparas with perinatal anxiety disorders admitted to the hospital from January 2020 to October 2024 were selected and divided into two groups according to the random number method.The control group(n=75)received CBT,and the observation group(n=75)received mindfulness-based stress reduction combined with CBT.The anxiety and depressive emotions,as well as the mother-infant emotional bonding situation,were compared between the two groups.RESULTS After the intervention,the anxiety and depressive states in the observation group were lower than those in the control group(P<0.05).The mother-infant bonding(sense of pleasure,recognition,understanding,and love)in the observation group was higher than that in the control group,and the role adaptation ability was also higher than in the control group(P<0.05).CONCLUSION Mindfulness-based stress reduction combined with CBT can reduce perinatal anxiety disorders in primiparas,promote mother-infant bonding,and improve their ability to adapt to the mother role.

文摘Depression is the most common mental disorder among perinatal women,with its incidence showing an annual increasing trend.Depression poses severe harms to the health of mothers and infants,thus requiring high attention from perinatal women themselves,their families,and society.Studies have shown that there are numerous influencing factors for depression in perinatal women,the most common of which include place of residence,monthly family income,recent appetite,mother-in-law and daughter-in-law relationship,personal history of anxiety and depression,obstetric complications during pregnancy,fear of childbirth,utilization of support,positive coping,and susceptible personality.Based on empirical research,this paper conducts an in-depth study and discussion on the current status of depression and its influencing factors in perinatal women,aiming to provide a basis for formulating scientific and effective preventive and intervention measures,and to contribute modestly to effectively reducing the adverse impact of depression on the physical and mental health of mothers and infants.
文摘Nutrition during perinatal period is more critical for the developme nt of the immune system than during adulthood, and the relationship between earl y nutrition and diseases in later life has been established. In humans and labor atory animals, the plasticity of metabolic function in foetuses or neonates enab les them to adapt to malnutrition for survival; however, such an adaptation, as usually evidenced by retarded growth, stunted development of lymphoid organs and impaired immunocompetence, can maintain and persist into later life even when n utrition is improved. Early nutrition may thus programme' the immune system of a nimals. Limited experimental studies have also revealed that long-term immunity against nematode parasites in sheep can be enhanced by a short-term protein su pplementation shortly after weaning, a form of 'nutritional programming', but su ch an effect appears to vanish if the nutritional status of young animals alread y meets at least the requirement for maintenance.

文摘Cell-based regenerative medicine is of growing interest in biomedical research. The role of stem cells in this context is under intense scrutiny and may help to define principles of organ regeneration and develop innovative therapeutics for organ failure. Utilizing stem and progenitor cells for organ replacement has been conducted for many years when performing hematopoietic stem cell transplantation. Since the first successful transplantation of umbilical cord blood to treat hematological malignancies, non-hematopoietic stem and progenitor cell populations have recently been identified within umbilical cord blood and other perinatal and fetal tissues. A cell population entitled mesenchymal stromal cells (MSCs) emerged as one of the most intensely studied as it subsumes a variety of capacities: MSCs can differentiate into various subtypes of the mesodermal lineage, they secrete a large array of trophic factors suitable of recruiting endogenous repair processes and they are immunomodulatory.Focusing on perinatal tissues to isolate MSCs, we will discuss some of the challenges associated with these cell types concentrating on concepts of isolation and expansion, the comparison with cells derived from other tissue sources, regarding phenotype and differentiation capacity and finally their therapeutic potential.
文摘In the epidemiologic context of maternal obesity and type 2 diabetes(T2D),the incidence of gestational diabetes has significantly increased in the last decades.Infants of diabetic mothers are prone to various neonatal adverse outcomes,including metabolic and hematologic disorders,respiratory distress,cardiac disorders and neurologic impairment due to perinatal asphyxia and birth traumas,among others.Macrosomia is the most constant consequence of diabetes and its severity is mainly influenced by maternal blood glucose level.Neonatal hypoglycemia is the main metabolic disorder that should be prevented as soon as possible after birth.The severity of macrosomia and the maternal health condition have a strong impact on the frequency and the severity of adverse neonatal outcomes.Pregestational T2 D and maternal obesity significantly increase the risk of perinatal death and birth defects.The high incidence of maternal hyperglycemia in developing countries,associated with the scarcity of maternal and neonatal care,seriously increase the burden of neonatal complications in these countries.
文摘Hepatitis C virus(HCV) infection is a major global health issue.Infection by the HCV can cause acute and chronic liver diseases and may lead to cirrhosis,hepatocellular carcinoma or liver failure.The World Health Organization estimates that approximately 3% of the world population have been infected with HCVand the worldwide prevalence is between 1% and 8% in pregnant women and between 0.05% and 5% in children.Following the introduction of blood product screening,vertical transmission becomes the leading cause of childhood HCV infection.The prevalence of pediatric HCV infection varies from 0.05% to 0.36% in developed countries and between 1.8% and 5% in the developing world.All children born to women with antiHCV antibodies should be checked for HCV infection.Though universal screening is controversial,selective antenatal HCV screening on high-risk populations is highly recommended and should be tested probably.Multiple risk factors were shown to increase the possibility of HCV vertical transmission,including coinfections with human immunodeficiency virus,intravenous drug use and elevated maternal HCV viral load,while breastfeeding and HCV genotypes have been studied to have little impact.At present,no clinical intervention has been clearly studied and proved to reduce the HCV vertical transmission risk.Cesarean section should not be recommended as a procedure to prevent vertical transmission,however,breastfeeding is generally not forbidden.The high prevalence of global HCV infection necessitates renewed efforts in primary prevention,including vaccine development,as well as new approaches to reduce the burden of chronic liver disease.Future researches should focus on the interruption of vertical transmission,developments of HCV vaccine and directacting antivirals in infancy and early childhood.

文摘Fetuses and neonates are known to be high-risk groups for Methylmercury（MeHg）exposure.MeHg can be transferred to the fetus through the placenta and to newborn offspring through breast milk.The aim of the present study was to investigate the neurotoxic effects of low doses of MeHg（1 and 5 μg/m L in drinking water） administration,from gestational day 1 to postnatal day（PND） 21,on the neurobehavioral development of rats.The results showed that the no-observed-effect level of MeHg is somewhere in the range of 1-4 μg/mL.Neurobehavioral development analysis revealed a delayed appearance of cliff drop and negative geotaxis reflexes in the 5 μg/mL MeHg exposure group.Developmental exposure to MeHg affected locomotor activity functions for the females,but not for the males,implying that the female pups were more vulnerable than the male pups.All pups exposed to 5 μg/mL of MeHg showed a significant deficit in motor coordination in the rotarod test compared with controls,and the highest accumulated concentrations of Hg were found in the cerebellum,followed by the hippocampus and cerebral cortex,indicating that the cerebellum is a possible target for MeHg toxicity.We demonstrated adverse effects of developmental exposure to MeHg associated with tissue concentrations very close to the current human body burden of this persistent and bioaccumulative compound.
