I dysfunction in Parkinson's disease.Early pregnancy features complex signaling between fetal trophoblast cells and maternal endometrium directing major peri-implantation events including localized inflammation and remodeling to establish proper placental development. Proinflammatory mediators are important for conceptus attachment, but a more precise understanding of molecular pathways regulating this process is needed to understand how the endometrium becomes receptive to implantation. Zanubrutinib mw Both chemokine ligand 12 (CXCL12) and its receptor CXCR4 are expressed by fetal and maternal tissues. We identified this pair as a critical driver of placental angiogenesis, but their additional importance to inflammation and trophoblast cell survival, proliferation, and invasion imply a role in syncytia formation at the fetal-maternal microenvironment. We hypothesized that CXCL12 encourages both endometrial inflammation and conceptus attachment during implantation. We employed separate ovine studies to (1) characterize endometrial inflammation during early gestation in the ewe, and (2) establish functional implications of CXCL12 at the fetal-maternal interface through targeted intrauterine infusion of the CXCR4 inhibitor AMD3100. Endometrial tissues were evaluated for inflammatory mediators, intracellular signaling events, endometrial modifications, and trophoblast syncytialization using western blotting and immunohistochemistry. Endometrial tissue from ewes receiving CXCR4 inhibitor demonstrated dysregulated inflammation and reduced AKT and NFKB, paired with elevated autophagic activity compared to control. Immunohistochemical observation revealed an impairment in endometrial surface remodeling and diminished trophoblast syncytialization following localized CXCR4 inhibition. These data suggest CXCL12-CXCR4 regulates endometrial inflammation and remodeling for embryonic implantation, and provide insight regarding mechanisms that, when dysregulated, lead to pregnancy pathologies such as intrauterine growth restriction and preeclampsia.
Parametric g-computation is an analytic technique that can be used to estimate the effects of exposures, treatments and interventions; it relies on a different set of assumptions than more commonly used inverse probability weighted estimators. Whereas prior work has demonstrated implementations for binary exposures and continuous outcomes, use of parametric g-computation has been limited due to difficulty in implementation in more typical complex scenarios.
We provide an easy-to-implement algorithm for parametric g-computation in the setting of a dynamic baseline intervention of a baseline exposure and a time-to-event outcome. To demonstrate the use of our algorithm, we apply it to estimate the effects of interventions to reduce area deprivation on the cumulative incidence of sexually transmitted infections (STIs gonorrhea, chlamydia or trichomoniasis) among women living with HIV in the Women's Interagency HIV Study.
We found that reducing area deprivation by a maximum of 1 tertile for all women would lead to a 2.7% [95% confidence interval (CI) 0.1%, 4.3%] reduction in 4-year STI incidence, and reducing deprivation by a maximum of 2 tertiles would lead to a 4.3% (95% CI 1.9%, 6.4%) reduction.
As analytic methods such as parametric g-computation become more accessible, epidemiologists will be able to estimate policy-relevant effects of interventions to better inform clinical and public health practice and policy.

While having a good referral policy in place is important, equally important is its effective implementation. Using the implementation of a policy on referral of obstetric emergencies in Shanghai as a case, we illustrate the application of the 'Inhabited Institutions' analytical approach for studying policy implementation. In doing so, our study highlights how 'referral' is a quintessential systems process embedded in institutional, social and historical contexts. We show that multiple institutional logics, in the form of explicit and tacit organizing principles and assumptions, intersect to influence and shape actors' actions, sometimes with good outcomes and sometimes with poor outcomes. We reveal the embedded agency of frontline healthcare managers and providers across different levels of care. We show how frontline managers and providers, operating under conditions of uncertainties and ambiguities in organizational processes, actively draw upon their experience and network capital to creatively adapt to get referrals done in a timely manner to save lives of critically ill pregnant women. From our findings, two sets of linked implications emerge for strengthening referral systems. Given that referral often involves ill and complicated cases, getting referrals right depends on the exercise of discretion and judgement by those at the frontline to arrive at timely and workable solutions-health systems need to recognize this. We also conclude that to get referrals right, while one needs clearly defined policies and implementation processes that are locally appropriate, well understood by all concerned and easy to follow, this is not enough. In addition, explicit measures that enable the exercise of discretion and judgement at the frontline need to be locally identified and adopted.
Although stages of reproductive aging for women in the general population are well described by STRAW+10 criteria, this is largely unknown for female adolescent and young adult cancer survivors (AYA survivors).
This work aimed to evaluate applying STRAW + 10 criteria in AYA survivors using bleeding patterns with and without endocrine biomarkers, and to assess how cancer treatment gonadotoxicity is related to reproductive aging stage.
The sample (n = 338) included AYA survivors from the Reproductive Window Study cohort. Menstrual bleeding data and dried-blood spots for antimüllerian hormone (AMH) and follicle-stimulating hormone (FSH) measurements (Ansh DBS enzyme-linked immunosorbent assays) were used for reproductive aging stage assessment. Cancer treatment data were abstracted from medical records.
Among participants, mean age 34.0 ± 4.5 years and at a mean of 6.9 ± 4.6 years since cancer treatment, the most common cancers were lymphomas (31%), breast (23%), and thyroid (17%). Twenty-nine percent were unclassifiable by STRAW + 10 criteria, occurring more frequently in the first 2 years from treatment.
