Nurturing care assets for food security: a community asset mapping approach.

BACKGROUND: Zip codes classified by the Food Insecurity Index with moderate and high food insecurity (FI) risk can be a threat to the health and well-being of children during the first 1,000 days (from pregnancy to 2 years). The presence of nurturing care assets (i.e., stable environments that promote health and nutrition, learning opportunities, security and safety, and responsive relationships) can contribute to supporting families and their communities, and ultimately reduce systemic barriers to food security. We aimed to identify and characterize nurturing care assets in under-resourced communities with moderate and high FI risk. METHODS: Four steps were used to conduct a Community Asset Mapping (CAM): (1) review of community documents across five zip codes in Clark County, Nevada (2), engagement of community members in identifying community assets (3), definition of the assets providing nurturing care services, and (4) classification of assets to nurturing care components, i.e., good health, adequate nutrition, safety and security, opportunities for early learning, and responsive caregiving. The Food Insecurity Index was used to determine FI risk in each zip code. Analyses explored whether disparities in nurturing care assets across zip codes with moderate and high FI exist. RESULTS: We identified 353 nurturing care assets across zip codes. A more significant number of nurturing care assets were present in zip codes with high FI risk. The adequate nutrition component had the most assets overall (n = 218, 61.8%), while the responsive caregiving category had the least (n = 26, 7.4%). Most of the adequate nutrition resources consisted of convenience stores (n = 96), food pantries (n = 33), and grocery stores (n = 33). Disparities in the number and type of good health, early learning, and security and safety assets were identified within zip codes with high FI risk compared to moderate FI risk. CONCLUSIONS: The quantity and type of nurturing care assets can exacerbate existing demographic disparities across zip codes, which are tied to barriers to access to food in under-resourced communities in Clark County, Nevada. Co-creating a nurturing care asset-based zip code strategy to address high FI risk will require strengthening systems across existing nurturing care assets.

Refractory thoracic endometriosis syndrome with bilateral hemothorax.

Thoracic endometriosis syndrome (TES) is a rare disorder presenting with catamenial pneumothorax, hemothorax, hemoptysis or pulmonary nodules. Bilateral involvement is uncommon, and only a very few cases have been reported in the literature. We report a case of bilateral catamenial hemothorax in a patient with recurrent thoracic endometriosis. Despite multiple surgical interventions, the patient continued to develop hemopneumothorax coinciding with menses. Remission was finally achieved with the addition of gonadotropin-releasing hormone agonist, highlighting the effectiveness of postoperative adjuvant hormone therapy and supporting a combined surgical and medical approach in the treatment of TES in patients who desire future fertility.

The risk of embryo-endometrium asynchrony increases with maternal age after ovarian stimulation and IVF.

This retrospective cohort analysis examined the effects of maternal age on the incidence of factors associated with embryo-endometrium asynchrony in fresh autologous blastocyst transfer. The study included 1169 routine fresh autologous blastocyst transfers. The main outcome measure was asynchronous transfer defined by delayed (day 6) blastocyst transfer or elevated pre-ovulatory serum progesterone level. Compared with patients younger than 35 years, patients 35 years or older had increased risk of having at least one risk factor for asynchronous transfer, including premature progesterone elevation or delayed blastocyst transfer (RR 1.36; 95% CI 1.24 to 1.50). The older group had increased risk of simultaneously having both risk factors (RR 1.61, 95% CI 1.17 to 2.21) compared with the younger group. In patients younger than 35 years, live birth rate per transfer was 62.9% with day 5 transfer and low progesterone, declining to 27.9% for day 6 transfer combined with elevated progesterone. In patients 35 years or older, live birth rate per transfer was 38.0% with day 5 transfer and low progesterone, declining to 18.1% for day 6 transfer combined with elevated progesterone. Indicators of embryo-endometrium asynchrony increase in prevalence as women age and asynchrony disproportionately decreases birth rates in older patients.

Efficient generation of human hepatocytes by the intrahepatic delivery of clonal human mesenchymal stem cells in fetal sheep.

UNLABELLED: Alternative methods to whole liver transplantation require a suitable cell that can be expanded to obtain sufficient numbers required for successful transplantation while maintaining the ability to differentiate into hepatocytes. Mesenchymal stem cells (MSCs) possess several advantageous characteristics for cell-based therapy and have been shown to be able to differentiate into hepatocytes. Thus, we investigated whether the intrahepatic delivery of human MSCs is a safe and effective method for generating human hepatocytes and whether the route of administration influences the levels of donor-derived hepatocytes and their pattern of distribution throughout the parenchyma of the recipient's liver. Human clonally derived MSCs were transplanted by an intraperitoneal (n = 6) or intrahepatic (n = 6) route into preimmune fetal sheep. The animals were analyzed 56-70 days after transplantation by immunohistochemistry, enzyme-linked immunosorbent assay, and flow cytometry. The intrahepatic injection of human MSCs was safe and resulted in more efficient generation of hepatocytes (12.5% +/- 3.5% versus 2.6% +/- 0.4%). The animals that received an intrahepatic injection exhibited a widespread distribution of hepatocytes throughout the liver parenchyma, whereas an intraperitoneal injection resulted in a preferential periportal distribution of human hepatocytes that produced higher amounts of albumin. Furthermore, hepatocytes were generated from MSCs without the need to first migrate/lodge to the bone marrow and give rise to hematopoietic cells. CONCLUSION: Our studies provide evidence that MSCs are a valuable source of cells for liver repair and regeneration and that, by the alteration of the site of injection, the generation of hepatocytes occurs in different hepatic zones, suggesting that a combined transplantation approach may be necessary to successfully repopulate the liver with these cells.
