Postoperative Bioactive Adrenomedullin Is Associated With The Onset Of Ards And Adverse Outcomes In Patients Undergoing Open Thoracoabdominal Aortic Surgery, Panagiotis Doukas, Oliver Hartmann, Jelle Frankort, Birte Arlt, Hanif Krabbe, Michael Johan Jacobs, Andreas Greiner, Jan Paul Frese, Alexander Gombert

Journal Articles

Cytokine-mediated systemic inflammation after open thoracoabdominal aortic aneurysm (TAAA) repairs plays a pivotal role in disrupting circulatory homeostasis, potentially leading to organ dysfunction. The bioactive form of adrenomedullin (bio-ADM) is a peptide hormone with immunomodulatory and vasomotor effects, making it a potential diagnostic agent in these cases. This retrospective, bicentric study, conducted between January 2019 and December 2022, recruited 36 elective open TAAA repair patients in two German centres. Serum and plasma samples were collected at multiple time points to measure bio-ADM levels. The primary objective was to evaluate the association of bio-ADM levels with the onset of acute respiratory …

Vascular Risk Profile And Changes Of Arterial Hypertension After Surgical Revascularization In Adult Moyamoya Patients, Patrick Haas, Lucas Moritz Wiggenhauser, Jonas Tellermann, Helene Hurth, Daniel Feucht, Marcos Tatagiba, Nadia Khan, Constantin Roder

Journal Articles

Moyamoya disease (MMD) is a rare stenoocclusive cerebral vasculopathy often treated by neurosurgical revascularization using extracranial-intracranial bypasses to prevent ischemic or hemorrhagic events. Little is known about the vascular risk profile of adult MMD patients compared to the general population. We therefore analyzed 133 adult MMD patients and compared them with data from more than 22,000 patients from the German Health Update database. Patients with MMD showed an age- and sex-adjusted increased prevalence of arterial hypertension, especially in women between 30 and 44 years and in patients of both sexes between 45 and 64 years. Diabetes mellitus was diagnosed significantly …

Sars-Cov-2 Viral Load In The Nasopharynx At Time Of First Infection Among Unvaccinated Individuals: A Secondary Cross-Protocol Analysis Of 4 Randomized Trials, Leigh H Fisher, Jia Jin Kee, Albert Liu, Claudia M Espinosa, April K Randhawa, James Ludwig, Craig A Magaret, Samuel T Robinson, Peter B Gilbert, Ollivier Hyrien, James G Kublin, Nadine Rouphael, Ann R Falsey, Magdalena E Sobieszczyk, Hana M El Sahly, Beatriz Grinsztejn, Glenda E Gray, Karen L Kotloff, Cynthia L Gay, Brett Leav, Ian Hirsch, Frank Struyf, Lisa M Dunkle, Kathleen M Neuzil, Lawrence Corey, Yunda Huang, Paul A Goepfert, Stephen R Walsh, Lindsey R Baden, Holly Janes, Covid-19 Prevention Network (Covpn)

Importance: SARS-CoV-2 viral load (VL) in the nasopharynx is difficult to quantify and standardize across settings, but it may inform transmission potential and disease severity.

Objective: To characterize VL at COVID-19 diagnosis among previously uninfected and unvaccinated individuals by evaluating the association of demographic and clinical characteristics, viral variant, and trial with VL, as well as the ability of VL to predict severe disease.

Design, setting, and participants: This secondary cross-protocol analysis used individual-level data from placebo recipients from 4 harmonized, phase 3 COVID-19 vaccine efficacy trials sponsored by Moderna, AstraZeneca, Janssen, and Novavax. Participants were SARS-CoV-2 negative at baseline …

Survival Predictive Nomograms For Non-Surgical Brain Metastases Patients From Non-Small Cell Lung Cancer Receiving Radiotherapy: A Population-Based Study, Peng Li, Jie Luo, Zilong Zheng, Lu Meng, Anqi Zhang, Wei Cao, Xiaomei Gong

Journal Articles

OBJECTIVE: A high number of Non-Small Cell Lung Cancer (NSCLC) patients with brain metastasis who have not had surgery often have a negative outlook. Radiotherapy remains a most common and effective method. Nomograms were developed to forecast the cancer-specific survival (CSS) and overall survival (OS) in NSCLC individuals with nonoperative brain metastases who underwent radiotherapy.

METHODS: Information was gathered from the Surveillance, Epidemiology, and End Results (SEER) database about patients diagnosed with NSCLC who had brain metastases not suitable for surgery. Nomograms were created and tested using multivariate Cox regression models to forecast CSS and OS at intervals of 1, …

Oncologic Outcomes After Clinically Node-Negative Salvage Laryngectomy, Jennifer H Gross, Mihir R Patel, Jeffrey M Switchenko, Tyler G Chan, H M Baddour, Azeem Kaka, Brian J Boyce, Nabil F Saba, Jonathan J Beitler, Mark El-Deiry

Journal Articles

IMPORTANCE: Controversy exists regarding management of the clinically node-negative neck in patients with recurrent larynx or hypopharynx cancers who received total laryngectomy after definitive radiation with or without chemotherapy.

OBJECTIVE: To explore clinical and oncologic outcomes after elective neck dissection vs observation in patients who received clinically node-negative salvage total laryngectomy.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study was performed from January 2009 to June 2021 at a single, high-volume tertiary care center. Follow-up was conducted through June 2021 for all patients. Survival outcomes were based on at least 2 years of follow-up. Patients aged 18 years or older with …

Plasma Growth Hormone Is A Potential Biomarker Of Response To Atezolizumab And Bevacizumab In Advanced Hepatocellular Carcinoma Patients, Yehia I Mohamed, Dan G Duda, Muhammad O Awiwi, Sunyoung S Lee, Lina Altameemi, Lianchun Xiao, Jeffrey S Morris, Robert A Wolff, Khaled M Elsayes, Rikita I Hatia, Aliya Qayyum, Shadi M Chamseddine, Asif Rashid, James C Yao, Armeen Mahvash, Manal M Hassan, Hesham M Amin, Ahmed Omar Kaseb

INTRODUCTION: Hepatocellular carcinoma (HCC) has limited systemic therapy options when discovered at an advanced stage. Thus, there is a need for accessible and minimally invasive biomarkers of response to guide the selection of patients for treatment. This study investigated the biomarker value of plasma growth hormone (GH) level as a potential biomarker to predict outcome in unresectable HCC patients treated with current standard therapy, atezolizumab plus bevacizumab (Atezo/Bev).

MATERIALS AND METHODS: Study included unresectable HCC patients scheduled to receive Atezo/Bev. Patients were followed to determine progression-free survival (PFS) and overall survival (OS). Plasma GH levels were measured by ELISA and …

Host Gut Resistome In Gulf War Chronic Multisymptom Illness Correlates With Persistent Inflammation, Dipro Bose, Somdatta Chatterjee, Ethan Older, Ratanesh Seth, Patricia Janulewicz, Punnag Saha, Ayan Mondal, Jeffrey M Carlson, Alan W Decho, Kimberly Sullivan, Nancy Klimas, Stephen Lasley, Jie Li, Saurabh Chatterjee

Journal Articles

Chronic multisymptom illness (CMI) affects a subsection of elderly and war Veterans and is associated with systemic inflammation. Here, using a mouse model of CMI and a group of Gulf War (GW) Veterans' with CMI we show the presence of an altered host resistome. Results show that antibiotic resistance genes (ARGs) are significantly altered in the CMI group in both mice and GW Veterans when compared to control. Fecal samples from GW Veterans with persistent CMI show a significant increase of resistance to a wide class of antibiotics and exhibited an array of mobile genetic elements (MGEs) distinct from normal …

Value Of Emergent Neurovascular Imaging For "Seat Belt Injury": A Multi-Institutional Study, F G Sherbaf, B Chen, T Pomeranz, M Shahriari, M E Adin, S Mirbagheri, E Beheshtian, R Jalilianhasanpour, J Pakpoor, J W Lazor, A Kamali, D M Yousem

BACKGROUND AND PURPOSE: Screening for blunt cerebrovascular injury in patients after motor vehicle collision (MVC) solely based on the presence of cervical seat belt sign has been debated in the literature without consensus. Our aim was to assess the value of emergent neurovascular imaging in patients after an MVC who present with a seat belt sign through a large-scale multi-institutional study.

MATERIALS AND METHODS: The electronic medical records of patients admitted to the emergency department with CTA/MRAs performed with an indication of seat belt injury of the neck were retrospectively reviewed at 5 participating institutions. Logistic regression analysis was used …
