Objective: Cancer therapies lead to chest pain (CP), shortness of breath (SOB), and/or tachydysrhythmias (TACH Y) requiring cardiac risk stratification including coronary computed tomographic angiography (CCTA). We posit that cancer patients with CP, SOB and/or TACH Y have greater odds of having coronary artery disease (CAD) identified by CCTA than those that do not.
Methods: Eligibility for this IRB-approved retrospective observational cohort included those with cancer that had CCTA performed. Groups were stratified with and without CP, SOB, and/or TACH Y. Electronic medical records were mined for appropriate CPT codes from 01012010 to 08312013. Demographics, cancer type, and clinical outcomes were obtained. Standard t tests, odds ratios, and frequencies were used.
Results: Of 176 participants identified; 84 were male (48 %) and 118 were Caucasian (67 %). Of those, 100/176 (57 %) had CP, SOB, and/or TACH Y; 72/100 (72 %) had CP; 10/100 (10 %) had TACH Y; and 18/100 (18 %) had SOB. Of the 72 with CP, 40 (56 %) had CAD; of the 10 with TACH Y, 6 (60 %) had CAD; of the 18 with SOB, and 10 (56 %) had CAD. Thus, a 2.6-fold increased odds of having CAD (56/100 = 56 %) compared to 25/76 (33 %) in the group with cancer without CP, SOB, and/or TACH Y (95 % CI = 1.40 to 4.83; p = 0.003).
Conclusion: Cancer patients with CP, SOB, and/or TACH Y have a 2.6-fold increased odds of having CAD compared to cancer patients without CP, SOB, and/or TACH Y (95 % CI = 1.40 to 4.83; p = 0.003).

Pleural effusion as an initial presentation of malignancy poses significant diagnostic challenges, particularly when linked to gynecologic cancers. We discuss the case of a 53-year-old female who presented with progressive dyspnea and a massive right-sided pleural effusion. Cytological analysis of the pleural fluid revealed malignant cells and immunohistochemical staining confirmed high-grade serous carcinoma (HGSC) of ovarian origin.

Chemical dosing constitutes an effective strategy for sulfide control in sewers; however, its efficacy requires further optimization and enhancement. In this study, a novel dosing strategy using the synergistic dosing of calcium peroxide (CaO) and ferrous ions (Fe) for sulfide control was proposed, and its efficacy in controlling sulfides was evaluated using a long-term laboratory-scale reactor. The results showed that adding CaO-Fe improves the effect of sulfide control.

Plant extracts and bacterial biofilm are acknowledged to offer impressive corrosion-inhibitory activities. However, anticorrosive properties of their combination are still less reported. Thus, in the present study, we aimed to evaluate the corrosion inhibition efficiency of Saccharum officinarum bagasse (SOB) plant extract, Pseudomonas chlororaphis (P.

Sulfur-oxidizing bacteria (SOB) play a vital role in the occurrence of sulfur oxidation intermediate (SOI) compounds often recalcitrant to currently available, abiotic treatment within metal mine tailings impoundments (TI). As inadvertent SOI discharge post-treatment can lead to the uncontrolled acidification of receiving environments, it becomes increasingly important to elucidate the environmental controls on SOB identities and sulfur cycling within these relatively unstudied systems. Here, results identified controlling factors on SOB community differentiation and associated metabolic pathway occurrence through integrated physicochemical, geochemical, and microbial field and experimental investigation across three summers (2016, 2017, 2021) in a stratified Northern Ontario base metal TI.
