Background: Despite guidelines from the American Academy of Pediatrics (AAP), many pediatric practices still do not have standardized screening processes in place to identify children with developmental delays. From April 2014 to April 2017, six federally qualified health center (FQHC) sites in Northern California implemented an intervention to increase (a) standardized developmental screening at recommended intervals and (b) follow-up care and support for early intervention services., Method: The intervention aimed to optimize each site's screening processes, supported by an automated electronic tablet-based system. To improve follow-up support, social workers were hired to conduct follow-up clinical assessments, provide psychosocial education and treatment, provide referrals and case management support, and collaborate with service partners. We analyze operational and implementation data to characterize site adoption, patient reach, implementation processes, and intervention effectiveness., Results: During the intervention's final year, when tablet-based screening was adopted, the sites screened an estimated 6,550 children ages 0-18 at 23 intervals in three domains (developmental, autism, and psychosocial/behavioral), compared to a baseline where they screened ages 0-3 at four intervals in one domain. Screening rates increased from 65.3% to 75.5% after automation was extended from the first to the second site, then to 91.8% after automation was expanded to the remaining sites. Follow-up visit rates ranged between 74% and 88%., Conclusions: Implementation of a multicomponent developmental and behavioral health screening and follow-up care intervention enabled FQHC sites to meet AAP recommendations and provide follow-up support. Disseminating the intervention may support population-level improvement in early detection and intervention for developmental delays and behavioral health concerns.

Introduction: MicroRNAs (miRNAs) have been shown to be altered in both CVD and T2DM and can have an application as diagnostic and prognostic biomarkers. miRNAs are released into circulation when the cardiomyocyte is subjected to injury and damage., Objectives: Measuring circulating miRNA levels in human plasma may be of great potential use for measuring the extent of damage to cardiomyocytes and response to exercise. This review is aimed to highlight the potential application of miRNAs as biomarkers of CVD progression in T2DM, and the impact of exercise on recovery., Methods: The review aims to examine whether the health improvements following exercise in T2DM patients are reflective of changes in expression of plasma miRNAs. For this purpose, studies were identified from the literature that have established a correlation between diabetes, disease progression and plasma miRNA levels. We also reviewed studies which looked at the effect of exercise on plasma miRNA levels., Results: The review identified miRNA signatures that are affected by T2DM and DHD and a subset of these miRNAs that are also affected by different types of exercise. This approach helped us to identify those miRNAs whose expression and function can be altered by regular bouts of exercise., Conclusions: miRNAs identified as part of this review can serve as tools to monitor the cardio-protective, anti-inflammatory and metabolic effects of exercise in people suffering from T2DM. Future research should focus on regulation of these miRNAs in T2DM and how they can be altered by appropriate exercise interventions., Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-022-01066-4., Competing Interests: Conflict of interestThe authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© The Author(s) 2022.)

New Findings: What is the central question of this study? This is the first study to assess the day-to-day reliability of passive leg movement-induced hyperaemia (PLM-H), an index of lower-limb microvascular function, in young, healthy women. What is the main finding and its importance? Passive leg movement-induced hyperaemia demonstrated good day-to-day reliability, comparable to other common indices of endothelial function, supporting the use of PLM-H to assess lower-limb microvascular function in women., Abstract: Passive leg movement-elicited hyperaemia (PLM-H) provides an index of lower-limb microvascular function. However, there is currently limited information regarding the reliability of PLM-H and no reliability information specific to women. The purpose of this study was to determine the reliability of PLM-H in women on two separate days. Seventeen young, healthy women [22 ± 3 years old (mean ± SD)] participated in two identical visits including three trials of PLM. Using duplex ultrasound, PLM-H was characterized by six indices: peak leg blood flow (LBF) and vascular conductance (LVC), peak change above baseline (Δpeak) for LBF and LVC, and area under the curve above baseline (AUC) during the first 60 s of PLM for LBF and LVC. The results demonstrated good day-to-day reliability of PLM-H characterized as peak LBF [r = 0.84, P < 0.001; intraclass correlation coefficient (ICC) = 0.84; coefficient of variation (CV) = 13.2%], peak LVC (r = 0.82, P < 0.001; ICC = 0.79; CV = 14.4%), Δpeak LBF (r = 0.83, P < 0.001; ICC = 0.82; CV = 17.8%) and Δpeak LVC (r = 0.83, P < 0.001; ICC = 0.80; CV = 16.5%). Characterization of PLM as AUC demonstrated moderate day-to-day reliability: AUC LBF (r = 0.71, P < 0.05; ICC = 0.70; CV = 31.2%) and AUC LVC (r = 0.78, P < 0.001; ICC = 0.74; CV = 27.1%). In conclusion, this study demonstrates that PLM-H has good reliability as an index of microvascular function; however, characterization of PLM-H as peak, Δpeak LBF and LVC is more reliable than AUC., (© 2021 The Authors.

Background Malignant gynecological tumors are the main cause of cancer-related deaths in women worldwide and include uterine carcinosarcomas, endometrial cancer, cervical cancer, ovarian cancer, and breast cancer. This study aims to determine the association between immune cell infiltration and malignant gynecological tumors and construct signatures for diagnosis and prognosis. Methods We acquired malignant gynecological tumor RNA-seq transcriptome data from the TCGA database. Next, the "CIBERSORT" algorithm calculated the infiltration of 22 immune cells in malignant gynecological tumors. To construct diagnosis and prognosis signatures, step-wise regression and LASSO analyses were applied, and nomogram and immune subtypes were further identified. Results Notably, Immune cell infiltration plays a significant role in tumorigenesis and development. There are obvious differences in the distribution of immune cells in normal, and tumor tissues. Resting NK cells, M0 Macrophages, and M1 Macrophages participated in the construction of the diagnostic model, with an AUC value of 0.898. LASSO analyses identified a risk signature including T cells CD8, activated NK cells, Monocytes, M2 Macrophages, resting Mast cells, and Neutrophils, proving the prognostic value for the risk signature. We identified two subtypes according to consensus clustering, where immune subtype 3 presented the highest risk. Conclusion We identified diagnostic and prognostic signatures based on immune cell infiltration. Thus, this study provided a strong basis for the early diagnosis and effective treatment of malignant gynecological tumors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Liu, Feng, Jiang, Xu, Li and Liu.)

New Findings: What is the central question of this study? The purpose of this study was to determine intra-individual reproducibility of follicular phase changes in endothelial function (flow-mediated dilatation) over two menstrual cycles in healthy, premenopausal women. What is the main finding and its importance? Phase changes in endothelial function were not consistent at the individual level across two menstrual cycles, which challenges the utility of interpreting individual responses over one cycle., Abstract: Evidence regarding the impact of menstrual phase on endothelial function is conflicting, and studies to date have examined responses only over a single cycle. It is unknown whether the observed inter-individual variability of phase changes in endothelial function reflects stable, inter-individual differences in responses to oestrogen (E 2 ; a primary female sex hormone). The purpose of this study was to examine changes in endothelial function from the early follicular (EF; low-E 2 ) phase to the late follicular (LF; high-E 2 ) phase over two consecutive cycles. Fourteen healthy, regularly menstruating women [22 ± 3 years of age (mean ± SD)] participated in four visits (EF Visit 1 , LF Visit 2 , EF Visit 3 and LF Visit 4 ) over two cycles. Ovulation testing was used to determine the time between the LF visit and ovulation. During each visit, endothelial function [brachial artery flow-mediated dilatation (FMD)], E 2 and progesterone were assessed. At the group level, there was no impact of phase or cycle on FMD (P = 0.48 and P = 0.65, respectively). The phase change in FMD in cycle 1 did not predict the phase change in cycle 2 (r = 0.03, P = 0.92). Using threshold-based classification (2 × typical error threshold), four of 14 participants (29%) exhibited directionally consistent phase changes in FMD across cycles. Oestrogen was not correlated between cycles, and this might have contributed to variability in the FMD response. The intra-individual variability in follicular fluctuation in FMD between menstrual cycles challenges the utility of interpreting individual responses to phase over a single menstrual cycle., (© 2021 The Authors.

Purpose: To evaluate the efficacy and adverse effects of using low-dose intravitreal triamcinolone acetonide (IVTA) to preserve vision in polypoidal choroidal vasculopathy (PCV) eyes., Methods: This retrospective chart review study examined 8 eyes of 7 PCV patients, for whom verteporfin photodynamic therapy (vPDT) or antivascular endothelial growth factor (VEGF) therapy was not affordable/available and also with intolerable risk because of underlying cardiovascular and/or cerebrovascular ischemia. Low-dose IVTA (1 mg/0.025 mL) monotherapy was administered and repeated every 4 weeks if intraretinal edema or subretinal fluid persisted., Results: The median follow-up time was 26.4 months. Three eyes (3/8) maintained their initial best-corrected visual acuity and 4 eyes (4/8) exhibited improvement, whereas 1 eye (1/8) sustained some loss. The mean injection number per month was 0.7 for the first 6 months, after which it decreased to 0.4. In regard to adverse effects, intraocular pressure (IOP) of more than 21 mmHg was noted as persisting for a few weeks in 4 eyes and that of more than 30 mmHg was noted once in 1 eye. The increased IOP was adequately controlled by using IOP-lowering agents. Two initially phakic eyes each underwent cataract surgery in the 12th and 14th months after treatment., Conclusions: Low-dose IVTA therapy may be valuable for preserving the vision of PCV patients, while vPDT or anti-VEGF is not affordable/available or of those with underlying diseases for whom anti-VEGF therapy is with intolerable risk.

Ovarian cancer is characterized by a rapid intraperitoneal spread combination with ascites accumulation. However, the exact mechanisms for ovarian cancer intraperitoneal dissemination remain unknown. Visfatin has recently been established as a novel adipokine and its serum level is increased in various cancers. Here, we identified that the elevated level of visfatin in ascites was associated with ovarian cancer intraperitoneal dissemination. Using the transwell cell migration assay and the wound-healing assay, we found that ascites-derived visfatin could promote migration of Caov-3 cells. Meanwhile, visfatin could induce the aggregation of actin stress fibers and the formation of lamellipodia and filopodia in Caov-3 cells, concomitant with a shift of G-actin to F-actin. Inhibition of actin polymerization with cytochalasin D obviously abolished the effects of visfatin on the migration of Caov-3 cells. Further results showed that visfatin triggered Rho activation and its downstream cofilin phosphorylation in a time-dependent manner, which led to actin polymerization. More importantly, visfatin-induced Caov-3 cell migration was effectively blocked by C3 exoenzyme and Y27632, Rho, and ROCK inhibitor, respectively. Thus, our study showed that ascites-derived visfatin promoted migration of ovarian cancer cells through Rho/ROCK signaling-mediated actin polymerization, which was required for ovarian cancer intraperitoneal dissemination. These findings offered a novel molecular mechanism responsible for ovarian cancer intraperitoneal dissemination, which might be a potential target for ovarian cancer management.

This study aimed to induce malignant transformation of endometriosis in Sprague-Dawley rats by hyperestrogenemia and type II diabetes and evaluate its similarity with human disease in biological features. Rats with surgically induced endometriosis were randomized into two groups: those treated with estradiol (5 mg/kg three times/week after surgery), streptozotocin (25 mg/kg, 1 month after surgery), and high carbohydrate-and-fat feed (Es group); and those treated with placebo saline and standard feed (control group). All rats were randomly killed 2, 4, or 8 months after surgery. The endometriosis lesions and the corresponding eutopic endometria were subjected to morphological evaluation, TUNEL, and immunohistochemical analysis for the expressions of proliferating cell nuclear antigen, phosphatase and tensin homolog, phosphorylated protein kinase B, and phosphorylated mammalian target of rapamycin proteins. In the Es group, three cases (6.0%) of endometriosis showed atypical hyperplasia accompanied by simple hyperplastic eutopic endometria, and two cases (4.0%) of endometriosis showed endometrioid carcinoma accompanied by atypical hyperplastic eutopic endometria. In the Es group, the activity of organelles and the expressions of proliferating cell nuclear antigen, phosphorylated protein kinase B, and phosphorylated mammalian target of rapamycin increased, and the level of phosphatase and tensin homolog and TUNEL positivity decreased progressively in the order of endometriosis, atypical endometriosis, and malignant endometriosis. The same tendency was found in the corresponding eutopic endometria. The induced malignant endometriosis showed similarities with human disease in the pathological process and histomorphological and molecular biological features. The method is feasible. The malignant transformations of endometriosis and eutopic endometria may have correlations and similarities, but the former may suffer a higher risk of canceration., (© 2014 The Authors.
