{"title":"Views and experiences of infertile women regarding the role of gluten in their infertility","authors":"J. Bold, D. Diamantopoulou","doi":"10.26502/ogr0104","DOIUrl":"https://doi.org/10.26502/ogr0104","url":null,"abstract":"Background: Prevalence rates for infertility have increased globally. Untreated coeliac disease (CD) and gluten sensitivity can affect fertility. Guidelines encourage testing of women with unexplained infertility for CD and case studies demonstrate pregnancies after introducing a gluten-free diet (GFD). Aims: To understand the experiences of women diagnosed with infertility, investigating the potential role of gluten, including testing and implementation of a GFD. Methods: Participants completed an online survey that included open and closed questions which were coded inductively and analysed using thematic and content analysis. Findings: 29 UK based women completed the survey. The majority identified as White, with one Asian/Asian British, one Mixed, and one Arab participant. Only four had not undergone fertility treatment. Twelve had unexplained infertility, while seven had no diagnosis. Five had primary infertility and five had a secondary infertility diagnosis. TA identified six themes: (1) Experience with gluten in infertility, (2) Experiences with testing for CD, (3) Health beliefs/concerns regarding gluten, (4) Other interventions to help with infertility, (5) Nutritional support for women with infertility, (6) Infertility experience. A GFD alleviated symptoms for those with both intestinal and extra-intestinal symptoms. Participants felt unprepared for CD testing and that healthcare personnel did not treat symptoms seriously. Conclusion: Awareness of extraintestinal manifestations of CD, including unexplained infertility, should be increased amongst healthcare professionals. Women with unexplained infertility should be screened for CD, even without the presence of intestinal symptoms. Women with infertility choosing to implement a GFD need to be better supported.","PeriodicalId":74336,"journal":{"name":"Obstetrics and gynecology research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69351897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method: A retrospective cohort design was employed. Data for a cohort of 1183 participants were randomly divided into derivation (n = 578) and validation (n = 585) datasets. Inclusion criterion was women without chronic hypertension. Primary outcome was Gestational hypertension. A questionnaire and data abstraction form were used for data collection. Chi square (χ2) test, independent sample t-test and multivariate logistic regression (to derive the prediction model) were used for data analysis. For each significant variable, a score was calculated by multiplying coefficient (β) by 100 and rounding to the nearest integer. Discrimination was estimated by used of the c-statistic. Results: DBP, SBP, hypertension in previous pregnancy, stress and smoking (scores 10, 6, 210, 56 and 18, respectively) were predictors of incident GH. The model accuracy was assessed by the area under the receiver operating characteristic curve (AUC), with optimal cut-off value 936. With the derivation dataset, sensitivity, specificity and AUC of the model were 75.9%, 80.8% and 0.828 (95% CI 0.772–0.884) respectively. The model was validated by dividing the aggregated scores into three ranges (low, moderate and high) and their cumulative incidence calculated which were; 3.5%, 6.1% and 39.4%, respectively, in the derivation dataset and 4.7%, 6.2% and 30.2%, respectively, in the validation dataset. Calibration was good in both cohorts. The negative predictive value of women in the development cohort at high risk of GH was 92.0% compared to 94.0% in the validation cohort. Conclusions: The prediction model revealed adequate performance after validation in an independent cohort and can be used to classify women into high, moderate or low risk of developing GH. It contributes to efforts to provide clinical decision-making support to improve maternal health and birth outcomes.","PeriodicalId":74336,"journal":{"name":"Obstetrics and gynecology research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69351894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study design: prospective observational study. Methods: Four centres were established to collect data on a representative sample of each province. Along with haematological measures, sociodemographic data were obtained and placed into a predefined online proforma. SPSS v 20 was used to analyse the data. Frequencies and percentages were calculated for categorical variables, whereas means and standard deviations were used to represent scales. Results of all four provinces were analysed and compared for similarities and differences. Results: A total of 2060 female patients fulfilling our inclusion criteria from all four provinces were Obstet Gynecol Res 2022; 5 (1): 034-040 DOI: 10.26502/ogr076 Obstetrics and Gynecology Research Vol. 5 No. 1– March 2022. 35 included in the study. Four hundred and sixty (22%) of the total population were in the first trimester, 785 (38%) were in the second, and 815 (40%) were in the third trimester of pregnancy. The study population's mean age was 28 ± 5.033 years. The mean haemoglobin concentration was 10.78 ± 1.49 g/dl. The mean MCV was in the lower limits of normal, 79.73 ± 7.95 3FL. At a cut off haemoglobin concentration of 10.8 g/dl, 50% of the population had Haemoglobin concentrations lower than this value. In terms of mean Haemoglobin levels across Pakistan's provinces, the lowest haemoglobin level was recorded in Sind, at 10.34 ± 1.469 g/dl. It was followed by Punjab, with a mean Haemoglobin concentration of 10.8 g/dl + 1.89. However, the mean Haemoglobin concentration in KPK was significantly high with mean Hb of 11.01 ± 1.330 g/dl. Additionally, comparable Haemoglobin levels were seen in Baloch people, with a mean Hb of 10.95 ± 1.048 g/dl. So according to international standard anaemia was less prevalent in KPK and Balochistan. Conclusion: Anaemia during pregnancy is very common in Pakistani mothers, according to worldwide standards. However, Severe anaemia Hb<8g/dl, on the other hand, is uncommon. Interprovincial variation in haematological parameters is also notable in Pakistan. We may need to formulate local guidelines for diagnosing and managing anaemia.","PeriodicalId":74336,"journal":{"name":"Obstetrics and gynecology research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69352375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, premature atresia of the corpus luteum (CL) or suboptimal progesterone secretion after ovulation may result in the decreased ability to establish or maintain a pregnancy. The current limitations of serum hormone testing fail to give a complete picture of progesterone production across the luteal phase required for pregnancy. Results: Of the 185 enrolled women, 172 had complete cycles. Of the 172 women who demonstrated complete cycles, 54 (31.4%) women reported pregnancies. Thirty-five (64.8%) of these pregnancies resulted from a PdG positive cycle with a miscarriage rate of 14.3% (5/35). Nineteen pregnancies (35.2%) resulted from PdG negative cycles with a miscarriage rate of 89.5% (17/19). The association of a negative or positive cycle with pregnancy outcome was significant (two-sided p=0.0001). Positive PdG cycles are associated with increased pregnancy rates and lower odds of a first-trimester pregnancy loss. Conclusion: A consideration for luteal phase support with progesterone or ovulation induction in women with negative PdG cycles can be of benefit to increase pregnancy rates. Furthermore, the use of LH and PdG testing prior to conception can be used as a screening tool to potentially identify women who are at risk of subfertility and at a higher risk of first-trimester pregnancy loss related to low progesterone.","PeriodicalId":74336,"journal":{"name":"Obstetrics and gynecology research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69352453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interns are exposed to a lot of fetal heart traces during their internship. Knowledge on this is gained by (undergraduate) teaching and by working with clinicians. With this prospective cohort study we aim to investigate if introducing a CTG e-learning makes interns feel better prepared and more competent in interpreting CTG. Methods: We evaluated a 1-hour CTG e-learning containing basic principles and interpretation skills. We used anonymous evaluation questionnaires. The answers of the questionnaires were entered in and examined with IBM® SPSS® statistics version 26. Results: Students with access to the CTG e-learning felt better prepared (p=0.001), more competent (p=0.001) and were more satisfied with the education (p=0.000). Students with or without access to the e-learning scored the same on the knowledge test (p=0.504).

Therefore, the objective of the study was to investigate the effect of behavior change communication (BCC) through the health development armies on the dietary practices of pregnant women. Methods: A two-arm parallel cluster randomized controlled community trial with baseline and endline measurements using quantitative data collection methods was conducted in Ambo district among 770 pregnant women (385 in control and 385 in intervention groups). Endpoint data from 372 intervention and 372 control groups were gathered, respectively. In the intervention group, health development armies delivered the BCC main message based on intervention protocol. The intervention began in July 2018, and data collection for the endline began in October, 2018. The control group received the standard care provided by the healthcare system during an ANC visit. The study of effect measure was done using a log-binomial model to estimate the adjusted relative risk and its 95% confidence interval (CI) of the risk factors for suboptimal dietary practice. Result: At the end of the study, the overall optimal dietary practice among the intervention group was 65.1%, while among the control group it was 34.9% (p< 0.001). Pregnant women who received intervention were 41.0% less likely to be at risk of being suboptimal in dietary practice compared to pregnant women who were in the control group (ARR = 0.591, 95%CI: 0.510-0.686). Conclusions: This study revealed that behavior change communication (BCC) through the health development armies is effective in improving the dietary practices of pregnant women.
