To reduce environmental risks and impacts from orphaned wells (abandoned oil and gas wells), it is essential to first locate and then plug these wells. Manual reading and digitizing of information from historical documents is not feasible, given the large number of wells. Here, we propose a new computational approach for rapidly and cost-effectively characterizing these wells.

This randomized phase III trial aimed to determine whether treatment with cisplatin and volume-directed radiation followed by carboplatin and paclitaxel for four cycles (chemoradiotherapy [C-RT]) increased recurrence-free survival (RFS) and overall survival (OS) when compared with carboplatin and paclitaxel for six cycles (chemotherapy [CT]) in locally advanced endometrial cancer (UC). Previously reported results showed that C-RT did not improve RFS compared with CT. Here we report the final OS analysis.

Castleman Disease (CD) is a rare lymphoproliferative disorder that can be separated into two primary forms: Unicentric Castleman disease (UCD) and multicentric Castleman disease (MCD). UCD is localized, while MCD is systemic. Though UCD generally has a favorable prognosis following surgical resection, more aggressive forms of this disease have been identified, including cases associated with dendritic and spindle cell proliferation.

Article Synopsis
  • The IGH::CCND1 translocation is linked to mantle cell lymphoma and plasma cell myeloma, where cyclin D1 is often over-expressed, typically without gene rearrangement.
  • A rare case of an elderly man presenting with splenic marginal zone lymphoma showed a heterozygous TP53 deletion, which later evolved into a large B-cell lymphoma with a CCND1 rearrangement at relapse.
  • This study is notable as it is the first to report a progression from splenic marginal zone lymphoma with TP53 deletion to large B-cell lymphoma with CCND1 rearrangement, highlighting clonal relatedness between the two lymphoma stages.

Article Synopsis
  • Endometrial cancer (EC) is the most common gynecological cancer in the U.S., with obesity contributing to 57% of cases, emphasizing the need to study its molecular mechanisms in relation to obesity.
  • The research found that obese EC patients had higher levels of extracellular vesicles (EVs) carrying oncogenic proteins, which are linked to increased cancer growth, inflammation, and changes in protein expression in both adipose and uterine tissues.
  • Treatments with small molecule inhibitors like HO-3867 and Metformin were effective in reducing EV secretion, slowing cancer cell proliferation, and inhibiting the early stages of cancer development in high-fat diet-induced models.

In the United States, hundreds of thousands of undocumented orphan wells have been abandoned, leaving the burden of managing environmental hazards to governmental agencies or the public. These wells, a result of over a century of fossil fuel extraction without adequate regulation, lack basic information like location and depth, emit greenhouse gases, and leak toxic substances into groundwater. For most of these wells, basic information such as well location and depth is unknown or unverified.

The use of glucagon-like peptide-1 receptor agonists (GLP-1RA) has experienced rapid growth amidst the obesity epidemic in the United States. While originally developed for glucose control in Type 2 Diabetes Mellitus, the scope of these agents now extends to encompass weight loss and cardiovascular risk reduction. GLP-1RAs have the potential to induce significant weight loss, in combination with lifestyle modifications, among adults who are overweight or obese.

Article Synopsis
  • Deficient DNA mismatch repair (dMMR) serves as a biomarker indicating a better response to PD-1 blockade immunotherapy in solid tumors, including diffuse large B-cell lymphoma (DLBCL).
  • In a study involving a large cohort of DLBCL patients, genetic dMMR was found infrequently and linked to a more favorable immune microenvironment but did not show a strong prognostic impact.
  • Additionally, while phenotypic dMMR was also rare, its presence correlated with increased T cell activity, suggesting that PD-1 T cells may selectively target tumor cell subsets with dMMR, which has implications for the efficacy of immunotherapy in DLBCL.

Background: Ovarian cancer has the highest mortality among gynecologic cancers, primarily because it typically is diagnosed at a late stage and because of the development of chemoresistance in recurrent disease. Improving outcomes in women with platinum-resistant ovarian cancer is a substantial unmet need. Activation of the glucocorticoid receptor (GR) by cortisol has been shown to suppress the apoptotic pathways used by cytotoxic agents, limiting their efficacy.
