LGBTQ Persons’ Use of Online Spaces to Navigate Conception, Pregnancy, and Pregnancy Loss: An Intersectional Approach

Navigating conception, pregnancy, and loss is challenging for lesbian, gay, bisexual, transgender, and queer (LGBTQ) people, who experience stigma due to LGBTQ identity, other identities (e.g., loss), and intersections thereof. We conducted interviews with 17 LGBTQ people with recent pregnancy loss experiences. Taking LGBTQ identity and loss as a starting point, we used an intracategorical intersectional lens to uncover the benefits and challenges of LGBTQ-specific and non-LGBTQ-specific pregnancy and loss-related online spaces. Participants used LGBTQ-specific online spaces to enact individual, interpersonal, and collective resilience. However, those with multiple marginalized identities (e.g., people of color and non-partnered individuals), faced barriers in finding support within LGBTQ-specific spaces compared to those holding privileged identities (e.g., White and married). Non-LGBTQ spaces were beneficial for some informational needs, but not community and emotional needs due to pervasive heteronormativity, cisnormativity, and a perceived need to educate. We conceptualize experiences of exclusion as symbolic annihilation and intersectional invisibility, and discuss clinical implications and design directions.

Placenta-Specific miR-125b Overexpression Leads to Increased Rates of Pregnancy Loss in Mice

Pregnancy loss (PL) is one of the common complications that women can experience during pregnancy, with an occurrence rate of 1 to 5%. The potential causes of pregnancy loss are unclear, with no effective treatment modalities being available. It has been previously reported that the level of miR-125b was significantly increased in placentas of PL patients. However, the role of miR-125b in the development of PL still remains unknown. In the current study, an miR-125b placenta-specific over-expression model was constructed by lentiviral transfecting zona-free mouse embryos followed by embryo transfer. On gestation day 15, it was observed that the placenta was significantly smaller in the miR-125b placenta-specific overexpression group than the control group. Additionally, the abortion rate of the miR-125b placenta-specific overexpression group was markedly higher than in the control group. The blood vessel diameter was larger in the miR-125b-overexpressing specific placenta. In addition, miR-125b-overexpressing HTR8 and JEG3 cell lines were also generated to analyze the migration and invasion ability of trophoblasts. The results showed that miR-125b overexpression significantly suppressed the migration and invasion ability of HTR8 and JEG3 cells. Overall, our results demonstrated that miR-125b can affect embryo implantation through modulating placenta angiogenesis and trophoblast cell invasion capacity that can lead to PL.

Role of miRNA polymorphism in recurrent pregnancy loss: a systematic review and meta-analysis

There are a plethora of publications on the role of miRNA gene polymorphism and its association with recurrent pregnancy loss (RPL), but a lack of uniformity in the studies available due to the variable subject population, heterogeneity and contrary results of significance. Rigorous data mining was done through PubMed, SCOPUS, Cochrane library, Elsevier and Google Scholar to extract the studies of interest published until June 2021. A total of eight SNPs of miRNAs have been included, where ≥2 studies per SNPs were available. Analysis was done on the basis of pooled odds ratios and 95% CI. This is the first meta-analysis on miRNA SNPs in RPL that suggests that rs11614913, rs3746444 and rs2292832 biomarkers may decrease the risk of RPL under different genetic models.

A comparative study to evaluate pregnancy related issues among women aged 35 years old and beyond

Background: The pregnancy complications associated with women over 35 years of age are becoming more frequent. Late or too late remains the thread bearing discussion these days. Multiple studies have reported that women with 35 years of age or beyond are more vulnerable to develop obstetric complications. The present study has been conducted to reckon the strength of the association between maternal age and obstetric issues pertaining to women.Methods: This prospective study considered 217 single consecutive pregnancies which were divided into two groups based on age of patients. Group A consists of 163 pregnant women aged < 35 years and group B consists of 54 pregnant patients aged ≥35 years. The study was conducted at government medical college, Lala-Ded, and hospital Srinagar.Results: In spite of the underlying mechanisms, rigorous statistical analysis revealed the negative impact of extreme maternal ages on pregnancy. We found a significant difference between group A and group B with respect to early pregnancy loss, C-section, antepartum, intrapartum and postpartum complications (p<0.001).Conclusions: Evidently, it was demonstrated that women aging 35 years or above are more vulnerable to develop multiple intrapartum and postpartum complications than younger women in group B.

Heart Rate Variability Indices as Possible Biomarkers for the Severity of Post-traumatic Stress Disorder Following Pregnancy Loss

Background: Psychological distress, such as posttraumatic stress disorder (PTSD), is commonly evaluated using subjective questionnaires, a method prone to self-report bias. The study's working hypothesis was that levels of autonomic dysfunction determined by heart rate variability (HRV) measures are associated with the severity of PTSD in women following pregnancy loss.Methods: This was an observational prospective cohort study with 53 patients enrolled. The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) PTSD scale (PCL-5) was used to assess the severity of PTSD in women after pregnancy loss. The cardiac autonomic function was assessed using HRV measurements during a deep breathing test using an HRV scanner system with wireless ECG enabling real-time data analysis and visualization. HRV measures were: standard deviation (SD) of normal R-R wave intervals [SDNN, ms], square root of the mean of the sum of the squares of differences between adjacent normal R wave intervals [RMSSD, ms], and the number of all R-R intervals in which the change in consecutive normal sinus intervals exceeds 50 milliseconds divided by the total number of R-R intervals measured [pNN50 = (NN50/n-1)*100%] [pNN50%].Results: The PCL-5 scores had a statistically significant association with HRV indices (SDNN; RMSSD, and pNN50%). Patients with PTSD had similar mean heart rate values as compared to patients without PTSD (PCL-5), but significantly higher SDNN [median[IQR, interquartile range]: 90.1 (69.1–112.1) vs. 52.5 (36.8–65.6)], RMSSD [59.4 (37.5–74.9) vs. 31.9 (19.3 – 44.0)], and PNN50% values [25.7 (16.4–37.7) vs. 10.6 (1.5–21.9)]. The SDNN of the deep breathing test HRV was effective at distinguishing between patients with PTSD and those without, with an AUC = 0.83 +/− 0.06 (95 % CI 0.94, p = 0.0001) of the ROC model.Conclusions: In this study, HRV indices as biomarkers of cardiac dysautonomia were found to be significantly related to the severity of PTSD symptoms in women after pregnancy loss.
