Objective: Given the unique cultural background, way of life, and physical environment of the Tibetan Plateau, this study aims to investigate the effects of health education using problem-based learning (PBL) approaches on the knowledge, attitude, practice, and coping skills of women with high-risk pregnancies in this region. Methods: 76 high-risk pregnancy cases were enrolled at Tibet’s Linzhi People’s Hospital between September 2023 and April 2024. 30 patients admitted between September 2023 and December 2023 were selected as the control group and were performed with regular patient education. 46 patients admitted between January 2024 and April 2024 were selected as the observation group and were performed regular patient education with problem-based learning approaches. Two groups’ performance on their health knowledge, attitude, practice and coping skills before and after interventions were evaluated, and patient satisfaction were measured at the end of the study. Results: There was no statistical significance (P P P Conclusions: Health education with problem-based learning approaches is worth promoting as it can help high-risk pregnant women in plateau areas develop better health knowledge, attitude and practice and healthier coping skills. Also, it can improve patient sanctification. 展开更多

Objective: To compare the clinical effects of uterine cavity observation and suction surgery system with ultrasound guided induced abortion in very early pregnancy induced abortion surgery. Method: Select 80 patients who requested termination of pregnancy due to early pregnancy from August 2022 to April 2023, and analyze the data. 40 patients who underwent ultrasound-guided induced abortion to terminate pregnancy were included in the control group, and 40 patients who underwent uterine cavity observation surgery to terminate pregnancy were included in the observation group. Compare the surgical time, number of times the straw enters the uterine cavity, incidence of complications, and menstrual recovery time between the two groups. Results: There was no statistically significant difference in the surgical time between the observation group and the control group, but the number of times negative pressure straws entered the uterine cavity and the incidence of surgical complications in the observation group were significantly lower than those in the control group (P Conclusion: Applying the uterine cavity observation and suction surgical system to terminate pregnancy in very early pregnancy has the advantages of minimal damage to the uterus and low incidence of surgical complications, greatly protecting the patient’s fertility. 展开更多

Introduction: The growing phenomenon of early pregnancies in Benin has adverse consequences on the lives of adolescent girls, impacting various social, health, economic, and educational aspects. This study aims to identify the factors associated with early pregnancies in the municipality of Bohicon in 2022. Materials and Methods: This is a case-control study conducted in Bohicon, involving 47 cases and 94 controls from 16 secondary and technical schools. Cases were selected exhaustively, while controls were randomly drawn from girls aged 10 to 19 in the same class who had never been pregnant. Matching was based on the type of institution and class. Data were collected through a questionnaire and analyzed using Epi info 7.2.1.0 and STATA 15 software, employing multiple conditional logistic regression (5% significance threshold) to identify factors related to early pregnancies. Results: The average age of adolescents was 17.63 years ± 0.09 for cases and 17.12 years ± 0.13 for controls. Associated factors included age over 16 years (p = 0.049), the marital status of the adolescent (single) (p = 0.001), and the monthly pocket money of the adolescent less than 10,000 FCFA (p = 0.031). Conclusion: Three factors related to early pregnancies were identified. To counteract this phenomenon and promote responsible sexuality among adolescents, it is essential to strengthen communication efforts aimed at modifying behaviors. 展开更多

BACKGROUND Colorectal cancer(CRC)is a serious threat worldwide.Although early screening is suggested to be the most effective method to prevent and control CRC,the current situation of early screening for CRC is still not optimistic.In China,the incidence of CRC in the Yangtze River Delta region is increasing dramatically,but few studies have been conducted.Therefore,it is necessary to develop a simple and efficient early screening model for CRC.AIM To develop and validate an early-screening nomogram model to identify individuals at high risk of CRC.METHODS Data of 64448 participants obtained from Ningbo Hospital,China between 2014 and 2017 were retrospectively analyzed.The cohort comprised 64448 individuals,of which,530 were excluded due to missing or incorrect data.Of 63918,7607(11.9%)individuals were considered to be high risk for CRC,and 56311(88.1%)were not.The participants were randomly allocated to a training set(44743)or validation set(19175).The discriminatory ability,predictive accuracy,and clinical utility of the model were evaluated by constructing and analyzing receiver operating characteristic(ROC)curves and calibration curves and by decision curve analysis.Finally,the model was validated internally using a bootstrap resampling technique.RESULTS Seven variables,including demographic,lifestyle,and family history information,were examined.Multifactorial logistic regression analysis revealed that age[odds ratio(OR):1.03,95%confidence interval(CI):1.02-1.03,P<0.001],body mass index(BMI)(OR:1.07,95%CI:1.06-1.08,P<0.001),waist circumference(WC)(OR:1.03,95%CI:1.02-1.03 P<0.001),lifestyle(OR:0.45,95%CI:0.42-0.48,P<0.001),and family history(OR:4.28,95%CI:4.04-4.54,P<0.001)were the most significant predictors of high-risk CRC.Healthy lifestyle was a protective factor,whereas family history was the most significant risk factor.The area under the curve was 0.734(95%CI:0.723-0.745)for the final validation set ROC curve and 0.735(95%CI:0.728-0.742)for the training set ROC curve.The calibration curve demonstrated a high correlation between the CRC high-risk population predicted by the nomogram model and the actual CRC high-risk population.CONCLUSION The early-screening nomogram model for CRC prediction in high-risk populations developed in this study based on age,BMI,WC,lifestyle,and family history exhibited high accuracy. 展开更多

Objective To investigate the efficacy and safety in women after caesarian section for termination of early pregnancies by treatment, or repeated treatment with mifepristone and misoprostol. Subjects and Methods A total of 213 pregnant women with amenorrhea of 34~69 d after caesarian section who asked for medical abortion were recruited, including 63 cases undergoing their second medical abortion. A total amount of mifeprisstone of 150 mg given in separate doses (25 mg×4 and 50 mg at the first time) was administered orally within 3 d, followed by misoprostol of 0.6 mg orally in the morning of d 3. Results The complete abortion rate was 92.5%, incomplete abortion was 4.7% and failure was 2.8%. Conclusion The sequential use of mifepristone and misoprostol could be successfully and repeatedly used for induced abortion in those women with a caesarian section history. Its efficacy was similar to that for ordinary population. Its safety and effectiveness were satisfactory. 展开更多

Increasing evidence suggests that epigenetic dysfunction may influence the stability of normal pregnancy. The ten-eleven translocation (TET) family and 5-hydroxymethylcytosine (5-hmC) were found to be linked with epigenetic reprogramming. The present study aimed to examine the expression of the TET family and 5-hmC in the villi of human embryos and compared their expression between normal pregnancy and early pregnancy loss (EPL). Embryonic villi were collected from normal pregnant women (control) experiencing medical abortion and from EPL patients at gestation ages of 6, 7 and 8 weeks. The mRNAs of TET family were analysed using quantitative polymerase chain reaction (qPCR), and TET proteins using Western blotting and immunohistochemical analysis. The MethylFlashTM Kit was used to quantify the absolute amount of 5-methylcytosine (5-mC) and 5-hmC. Our results showed that the expression of the TETs and 5-hmC in the normal villus decreased with increasing gestational age. Immunohistochemistry revealed that the TET proteins were expressed in the cytoplasm of trophoblasts and their expression was the highest in the 6-week tissue samples, which was consistent with the qPCR and Western blot results. The expression of TET1, TET2, and TET3 was lower in the villi in EPL group than in normal pregnancy group (P〈0.05 for all). It was concluded that the TET family and 5-hmC are critical in epigenetic reprogramming of human embryo. The findings also suggest that a deficiency of TETs in the villus might be associated with human EPL. 展开更多

Early detection and treatment can improve pregnancy outcomes. Objectives: To determine the prevalence, risk factors and predictors of GDM in early pregnancy at the University of Port Harcourt Teaching Hospital, (UPTH), Port Harcourt Nigeria. Methods: A cohort of 235 mothers who registered for antenatal care between 15 - 18 weeks of gestation at UPTH was prospectively studied. Their socio-demographic data, examination findings, anthropometric measurements, fasting blood sugar at booking and OGTT results at 28 weeks gestation were collated and entered into PC with SPSS for windows version 21.0 which was also used for the analysis. Variables were expressed as absolute numbers, percentages or means with standard deviations and significant differences determined using chi square test or the student “t” test as appropriate. The level of significance was set at P < 0.05. Results: Of the 235 participants, 35 (14.9%) developed GDM. Women who had GDM were significantly older (P = 0.001), had higher weight (t = 2.95, P = 0.01), BMI (t = 2.29, P = 0.02), abdominal skin fold thickness (t = 4.15, P = 0.001), blood pressure (t = 3.38, P = 0.001) compared to women who did not. Previous history of GDM was significantly different between two groups as χ2 = 93.56 and P = 0.001. Abdominal skin fold thickness and prior GDM history were found to be independent predictors of GDM on application of multiple logistic regression analysis. Conclusion: The prevalence of GDM in Port Harcourt is 14.9% and major risk factors are obesity, previous GDM history, advanced age and hypertension. Abdominal skin fold thickness ≥ 20 mm is an independent predictor. The risk of developing GDM can be predicted in early second trimester using algorithm incorporating risk factor screening and anterior abdominal wall skin fold thickness estimation. 展开更多

To investigate the characteristic food intake during early pregnancy in women with gestational diabetes mellitus (GDM) in a rural city in Aomori Prefecture, Japan, one hundred and twenty-one women were recruited and queried about their habitual dietary intake. Food intake of patients was assessed using the model nutritional balance chart at 12 - 16, 24 - 28, and 34 - 36 weeks of gestation. Of the 121 pregnant women examined, 19 were obese. During early pregnancy, food intake ratios of the obese women were significantly lower than those of the non-obese women for the categories of milk (p < 0.001) and sugar (p < 0.05). GDM group was 7 women among 19 women in obesity group during mid-pregnancy. During early pregnancy, women with GDM had significantly higher sugar intake ratios than women without GDM (p < 0.05). These results suggested that obese pregnant women are able to prevent GDM by limiting their sugar intake during early pregnancy. 展开更多

Early diagnosis of pregnancy plays an important role to minimize reproductive losses in farm animals.There are several methods for pregnancy diagnosis like profiling of reproductive hormones(such as progesterone and estrone sulfate),but sometimes they provide false-positive results.Embryo specific pregnancy markers,which delineate the presence and viability of the embryo,are considered as perfect for pregnancy determination.Pregnancy-associated glycoproteins are distinguished as the best indicator for the determination of early pregnancy,fetal number,and birth weight of kids.Pregnancy-associated glycoproteins are structurally correlated to aspartic proteinase and are communicated in the external epithelial cell layer of the placenta.They have been found to share about half amino acid sequence identity with pepsinogen,pepsin,cathepsin D and E.Dislike different individuals from aspartic proteinase family,numerous pregnancy-associated glycoproteins appear to be latent compound as a result of amino acid substitutions in and around the catalytic site.This review is to discuss the scope and prospects of pregnancy-associated glycoproteins as a pregnancy marker in farm animals,more specifically in goats. 展开更多

Objective To explore the effects on macaques’ menstrual recovery after terminating early pregnancy by focused ultrasound beams (FUB) Methods FUB was used to terminate early pregnancy in 5 macaques with gestation duration ranging from 37-66 d. Two circles after the recovery of menstruation, color Doppler flow imaging (CDFI) and magnetic resonance imaging (MRI) were used to estimate the shape, size and blood flow of uterus, and pathological examinations were performed to check against any lesions to uterine endometrium and ovary. Results Forty days after FUB abortion, menstruation recovered and the volume and duration of each macaque’s menstruation were not changed compared with those be- fore gestation. CDFI and MRI suggested that the size and shape of uterus were normal. The endometrial line was clear and no lesions were found in adjacent organs. Conclusion FUB termination of early pregnancy in macaques did not damage their ovarian tissue and had no influence on subsequent menstrual recovery.Key words: focused ultrasound beams (FUB); macaque; early pregnancy; menstrual 展开更多

A cross sectional transvaginal color Doppler study of the uteroplacental circulation was performed on 105 pregnant women with normal intrauterine pregnancy. Gestational age was ranged from 4 to 12 weeks. The blood flow velocity waveforms were obtained from four separate parts of the uteroplacental circulation: uterine, arcuate, radial, and spiral arteries. The resistance index (RI) and peak systolic velocity (PSV) were analyzed. The RI significantly decreased and PSV increased with advancing gestation in uterine artery and its branches (P<0 05). The RI gradully decreased from uterine artery through arcuate, radial to spiral arteries (P<0 05). At the same time, the PSV decreased from uterine artery then arcuate to radial artery, but PSV in spiral arteries were higher than that in radial artery (P<0 05). The results showed that transvaginal color Dopper ultrasonography was a simple, reliable method to assess the uteroplacental circulation in the early pregnancy; the detection of PSV was useful parameter for better understanding of physiological and pathophysiological hemodynamic changes as well as RI. 展开更多

Objective:To accurately detect pregnancy in local Aardi goats of Saudi Arabia before day 30 of pregnancy by using serum caprine pregnancy associated glycoproteins (caPAG) concentrations and to evaluate the effects of heat stress on early pregnancy and on caPAG concentrations in pregnant and non-pregnant goats.Methods:This study was to confirm the reliability of our methods in different seasons of the year. A new protocol to evaluate and improve Aardi goats' reproductive performance was implemented during summer and winter months. A total of 60 healthy mature Aardi goats were used (30 and 30 in the summer and winter, respectively). All were synchronized using an ovsynch protocol and then naturally mated (NM) to mature tested bucks. Conception rates and caPAG were measured and pregnancy was verified by ultrasonography.Results:Regardless of season, however, on day 23 and 35 post-NM, caPAGs were higher in sera of pregnant (P<0.05) than in non-pregnant goats, while there was no difference in caPAG concentrations on day 15. On day 23 and 35 post-NM, serum caPAG concentrations were higher (P<0.001) in the pregnant winter group than in the pregnant summer group, while no differences were found in non-pregnant goats. Measuring serum caPAG concentrations proved to be easy and accurate in assessing early stages of pregnancy (as early as 23 days post-NM) during both summer and winter seasons.Conclusions: It can be concluded that pregnancy rates were not affected by seasonal differences. The modified ovsynch program can be advantageous and worthwhile for its ease of use. When we add the accuracy of caPAG tests, such a program will help in detecting pregnancies in Aardi goats as early as 23 days post-NM, regardless of the season. 展开更多

The subjects were orally administered with RU486 of 50mg (Group Ⅰ). 50mg Q12hx 6 (GrouP Ⅱ),200mg(GrouP Ⅲ)or 600mg(Group Ⅳ).Vacuum aspiration(GrouP Ⅰ)or Methyl Carprost Suppository(PGOS 1.0mg)(GrouP Ⅱ-Ⅳ)was given 72h after the firsl dose followed by a 6--hour medl'cal survel'llance.Blood samples were collected on day 1-6,8,15,43 to measure the serum levels of β-hCG,E2,P,PRL,ACTH, Cortisol,T3,T4 and TSH in each subject.The results showed that no significant dose-effect relationship was observed in terms of clinical efficacy,vaginal bleeding or side effects.All four groups shared the same tendency of changes in serum levels of β-hCG,E2 and P.β-hCG levels increased by 50-100% (P<0.01)24h prior to treatment,and continued ic ipcrease following lreatment until the sac expulsion.EZ levels l'n each group reinal'ned higher than pre-treatment values with the gradual decline in P levels.β-hCG,E2 and P decreased drastically after abortion,levels of β-hCG,E2,P on day 5 were only 35-60% (P<0.01),32-46%(P<0.01)and 30-56%(P<0.01)of those on day 4 respectively.The mean PRL levels on day 2-4 in each group increased obviously but declined gradually following the sac ex.pulsion.During treatment,the respective cortisol levels increased dramatically,the average levels ofcortisol on day 2-4 were 30-40%(P<0.05) l'n GrouP Ⅰ-Ⅲ and 60%(P< 0.01) in Group Ⅳ higher as compared with day 1 values, while decreased rapidly af ter termination of pregnancy as indicated that cortisol levels on day 5 were only 67-81%(P<0.05) of those on day 4.The changes in ACTH,T3,T4,TSH levels were of no statistic sigulAance(P>0.05).This study indicated that RU486 has no dose-effect relationship when used for interruption of early pregnancy and its main action site seems neither in ovary nor in villi.It has some effects on pituitary-adrenal axis,especially in large dosage,however,it has no obvious impact on pituilary-thyroid axis.It seems that the changes in PRL serum levels were directly due to the drug itsed ifs clinical significance should be further studied. 展开更多

The participants were 50 primiparas who had undergone ART at two fertility treatment facilities in a metropolitan area in Japan. For the infertility reflection, they conducted an online reflection. Data were collected three times: at the 5th week of pregnancy (Time 1), the 8th week of pregnancy as the final consultation at the clinic (Time 2), and the 16th week of pregnancy as the final point of early pregnancy (Time 3). <strong>Results: </strong>The data from 40 participants were analyzed. More than 80% of the users of the online reflection positively evaluated the appropriateness and usefulness of the methods and contents. Organized thoughts and feelings by reflection were shown as the reasons for the usefulness. The evaluation of the online reflection showed a relatively strong correlation with the Care Need Satisfaction Scale (CNSS) for both Time 2 and Time 3, but the online reflection did not show a significant correlation with the other outcome variables. There were no significant differences in outcome variables between users and non-users of online reflection between Time 2 and Time 3. <strong>Conclusions:</strong> Attempts at the reflection in early pregnancy require modified methods that do not have a negative impact and lead to the fulfillment of needs. 展开更多
