Intraoperative end-tidal carbon dioxide levels are not associated with recurrence-free survival after elective pancreatic cancer surgery: a retrospective cohort study.

Background: Intraoperative end-tidal carbon dioxide concentrations (EtCO) values are associated with recurrence-free survival after colorectal cancer surgery. However, it is unknown if similar effects can be observed after other surgical procedures. There is now evidence available for target EtCO and its relation to surgical outcomes following pancreatic cancer surgery.

Low intraoperative end-tidal carbon dioxide levels are associated with improved recurrence-free survival after elective colorectal cancer surgery.

Study Objective: Higher levels of carbon dioxide (CO) increase the invasive abilities of colon cancer cells in vitro. Studies assessing target values for end-tidal CO concentrations (EtCO) to improve surgical outcome after colorectal cancer surgery are lacking. Therefore, we evaluated whether intraoperative EtCO was associated with differences in recurrence-free survival after elective colorectal cancer (CRC) surgery.

Uncovering the Obstacles-A Typology of Environmental and Contextual Factors Affecting Occupational Participation: A Scoping Review.

Importance: Environmental and contextual factors may facilitate or limit participation in daily activities. A detailed, systematic categorization of such factors enhances evaluation and intervention and promotes occupational engagement.

Objective: To develop an inclusive, detailed, and comprehensive typology of terms for environmental and contextual factors that affect occupational engagement and participation.

Intraoperative Predictor of Remission in Cushing Disease.

Background: Cushing disease represents a challenge for neurosurgeons, with high recurrence rates reported. Characteristics associated with remission are incompletely understood; thus, an intraoperative predictor for outcome would be valuable for assessing resection of adrenocorticotropic hormone (ACTH) secreting tissue.

Objective: To evaluate whether intraoperative ACTH measurement could predict outcome after surgery for Cushing disease.

Intraoperative Prediction of Long-Term Remission in Acromegaly.

Background: The features of long-term remission in acromegaly adenomectomy are incompletely understood. An intraoperative predictor for long-term outcome would be valuable for assessing resection of growth hormone (GH)-secreting tumors in real-time.

Objective: To evaluate whether intraoperative GH measurement could predict long-term outcomes for acromegaly.

Flt3L, LIF, and IL-10 combination promotes the selective in vitro development of ESAM cDC2B from murine bone marrow.

The development of two conventional dendritic cells (DC) subsets (cDC1 and cDC2) and the plasmacytoid DC (pDC) in vivo and in cultures of bone marrow (BM) cells is mediated by the growth factor Flt3L. However, little is known about the factors that direct the development of the individual DC subsets. Here, we describe the selective in vitro generation of murine ESAM CD103 XCR1 CD172a CD11b cDC2 from BM by treatment with a combination of Flt3L, LIF, and IL-10 (collectively named as FL10).

Facile Synthesis and In Vitro Activity of -Substituted 1,2-Benzisothiazol-3(2)-ones against Dengue Virus NS2BNS3 Protease.

Several new -substituted 1,2-benzisothiazol-3(2)-ones (BITs) were synthesised through a facile synthetic route for testing their anti-dengue protease inhibition. Contrary to the conventional multistep synthesis, we achieved structurally diverse BITs with excellent yields using a two-step, one-pot reaction strategy. All the synthesised compounds were prescreened for drug-like properties using the online Swiss Absorption, Distribution, Metabolism and Elimination (SwissADME) model, indicating their favourable pharmaceutical properties.

Emerging drugs for the treatment of adrenocortical carcinoma.

: Adrenocortical cancer (ACC) is a rare and aggressive disease with a median survival of 14-17 months and 5-year survival of around 20% for advanced disease. Emerging evidence of sub-groups of ACC with specific molecular drivers indicate ACC may be amenable to inhibition of receptor tyrosine kinases involved in growth and angiogenic signaling. A significant subset of patients may also be responsive to immune strategies.

The serotonin reuptake inhibitor Fluoxetine inhibits SARS-CoV-2 in human lung tissue.

To circumvent time-consuming clinical trials, testing whether existing drugs are effective inhibitors of SARS-CoV-2, has led to the discovery of Remdesivir. We decided to follow this path and screened approved medications "off-label" against SARS-CoV-2. Fluoxetine inhibited SARS-CoV-2 at a concentration of 0.

The SARS-CoV-2 RNA-protein interactome in infected human cells.

Characterizing the interactions that SARS-CoV-2 viral RNAs make with host cell proteins during infection can improve our understanding of viral RNA functions and the host innate immune response. Using RNA antisense purification and mass spectrometry, we identified up to 104 human proteins that directly and specifically bind to SARS-CoV-2 RNAs in infected human cells. We integrated the SARS-CoV-2 RNA interactome with changes in proteome abundance induced by viral infection and linked interactome proteins to cellular pathways relevant to SARS-CoV-2 infections.

PRKAR1A deficiency impedes hypertrophy and reduces heart size.

Protein kinase A (PKA) activity is pivotal for proper functioning of the human heart, and its dysregulation has been implicated in a variety of cardiac pathologies. PKA regulatory subunit 1α (R1α, encoded by the PRKAR1A gene) is highly expressed in the heart, and controls PKA kinase activity by sequestering PKA catalytic subunits. Patients with PRKAR1A mutations are often diagnosed with Carney complex (CNC) in early adulthood, and may die later in life from cardiac complications such as heart failure.

PKA Activates AMPK Through LKB1 Signaling in Follicular Thyroid Cancer.

Thyroid cancer affects about one percent of the population, and has seen rising incidence in recent years. Follicular thyroid cancer (FTC) comprises 10-15% of all thyroid cancers. Although FTC is often localized, it can behave aggressively with hematogenous metastasis, leading to an increased risk of cancer death.

Metastatic Adrenocortical Carcinoma: a Single Institutional Experience.

Adrenocortical carcinoma (ACC) is a rare malignancy with limited data to guide the management of metastatic disease. The optimal treatment strategies and outcomes of patients with metastatic ACC remain areas of active interest. We retrospectively reviewed patients with ACC who were treated with systemic therapy between January 1997 and October 2016 at The Ohio State University Comprehensive Cancer Center.

Nivolumab in Metastatic Adrenocortical Carcinoma: Results of a Phase 2 Trial.

Context: Systemic treatment of metastatic adrenocortical carcinoma (ACC) remains limited to chemotherapy and mitotane. Preliminary evidence suggesting that antitumor immune responses can be elicited in ACC has fostered interest in checkpoint inhibitors such as anti-PD-1 nivolumab.

Objective: The primary endpoint was objective response rate according to the response evaluation criteria in solid tumors.

Alterations in Sod2-Induced Oxidative Stress Affect Endocrine Cancer Progression.

Context: Although important advances have been made in understanding the genetics of endocrine tumors, cellular physiology is relatively understudied as a determinant of tumor behavior. Oxidative stress and reactive oxygen species are metabolic factors that may affect tumor behavior, and these are, in part, controlled by manganese-dependent superoxide dismutase (MnSod), the mitochondrial superoxide dismutase (encoded by SOD2).

Objective: We sought to understand the role of MnSod in the prognosis of aggressive human endocrine cancers and directly assessed the effect of MnSod under- or overexpression on tumor behavior, using established mouse thyroid cancer models.

Predictors of Postoperative Diabetes Insipidus Following Endoscopic Resection of Pituitary Adenomas.

Context: The development of diabetes insipidus (DI) following transsphenoidal resection of pituitary adenomas has been associated with higher postsurgical morbidity and longer hospitalizations. Identifying these patients promptly and efficiently can lead to improved health care outcomes.

Objective: We evaluated our institution's incidence of DI following pituitary adenoma resection and assessed for preoperative risk factors that were associated with postoperative DI.

Deletion of Rap1b, but not Rap1a or Epac1, Reduces Protein Kinase A-Mediated Thyroid Cancer.

Background: Thyroid cancer is an emerging health problem in the United States and worldwide. With incidence rates of thyroid cancer rapidly rising, the need to develop new treatment options is becoming a priority, and understanding the molecular mechanisms of this disease is crucial to furthering these efforts. Thyroid growth is driven by the TSH/cAMP/PKA signaling pathway, and it has previously been shown that activation of PKA through genetic ablation of the regulatory subunit Prkar1a (Prkar1a KO) is sufficient to cause follicular thyroid cancer in mouse models.

Elevated aggressive behavior in male mice with thyroid-specific Prkar1a and global Epac1 gene deletion.

Alterations in circulating thyroid hormone concentrations are associated with several psychological and behavioral disorders. In humans, behavioral disorders such as anxiety, depression, and attention-deficit hyperactivity disorder can be associated with thyroid disease. The Tpo-Cre;Prkar1a;Epac1 (R1A-Epac1KO) mice, originally bred to investigate the role of exchange protein directly activated by cAMP (Epac1) in follicular thyroid cancer, displayed self-mutilating and aggressive behaviors during casual observation.
