Formularies are intended to simplify clinical decision-making by collecting evidence-based information on drugs and their dosages. This study assessed the characteristics of sources used to support drug dosages and reference intervals for mammals in a specific exotic animal formulary, and how the sources had changed over five editions.

Each reference supporting drug dosages and reference intervals in the sections for ferrets, rabbits, rodents, hedgehogs and miniature pigs in all five editions of the formulary was evaluated and classified by two independent investigators in terms of the type of source cited. Univariable and multi-variable logistic regression models were built to evaluate changes between editions and sections.

In total, 1338 references supporting drug dosages and 180 references supporting reference intervals were included from all editions of the formulary. Primary sources were cited by 525 (39.2%) and 39 (21.7%) of the drug and reference interval references, respectively. For drug dosager time, practitioners should be aware that the evidence supporting several drugs and dosages was limited, and assess the information within the formulary critically.Current understanding of how odors impact intra-sex social behavior is based on those that increase intermale aggression. Yet, odors are often promoted to reduce fighting among male laboratory mice. It has been shown that a cage of male mice contains many proteins used for identification purposes. However, it is unknown if these proteins relate to social behavior or if they are uniformly produced across strains. This study aimed to compare proteomes from used nesting material and three sources (sweat, saliva, and urine) from three strains and compare levels of known protein odors with rates of social behavior. Used nesting material samples from each cage were analyzed using LC-MS/MS. Sweat, saliva, and urine samples from each cage's dominant and subordinate mouse were also analyzed. Proteomes were assessed using principal component analyses and compared to behavior by calculating correlation coefficients between PC scores and behavior proportions. Twenty-one proteins from nesting material either correlated with affiliative behavior or negatively correlated with aggression. Notably, proteins from the major urinary protein family, odorant binding protein family, and secretoglobin family displayed at least one of these patterns, making them candidates for future work. These findings provide preliminary information about how proteins can influence male mouse behavior. SIGNIFICANCE Research on how olfactory signals influence same sex social behavior is primarily limited to those that promote intermale aggression. However, exploring how olfaction modulates a more diverse behavioral repertoire will improve our foundational understanding of this sensory modality. In this proteome analysis we identified a short list of protein signals that correspond to lower rates of aggression and higher rates of socio-positive behavior. While this study is only correlational, it sets a foundation for future work that can identify protein signals that directly influence social behavior and potentially identify new murine pheromones.

Transcranial electrical stimulation (TES) is broadly investigated as a therapeutic technique for a wide range of neurological disorders. The electric fields induced by TES in the brain can be estimated by computational models. A realistic and volumetric approach to simulate TES (ROAST) has been recently released as an open-source software package and has been widely used in TES research and its clinical applications. Rigor and reproducibility of TES studies have recently become a concern, especially in the context of computational modeling.

Here we reviewed 94 clinical TES studies that leveraged ROAST for computational modeling. When reviewing each study, we pay attention to details related to the rigor and reproducibility as defined by the locations of stimulation electrodes and the dose of stimulating current. Specifically, we compared across studies the electrode montages, stimulated brain areas, achieved electric field strength, and the relations between modeled electric field and clinical outcomes.

We found that over 1800 individual heads have been modeled by ROAST for more than 30 different clinical applications. Similar electric field intensities were found to be reproducible by ROAST across different studies at the same brain area under same or similar stimulation montages.

This article reviews the use cases of ROAST and provides an overview of how ROAST has been leveraged to enhance the rigor and reproducibility of TES research and its applications.

Chronic venous insufficiency (CVI) affects >40% of the U.S. population; thus, intervention for symptomatic venous disease comprises a large portion of many vascular practices. The treatment of superficial CVI has evolved from open surgical treatment to minimally invasive endovenous closure, including both thermal and nonthermal techniques. Thrombotic complications of thermal ablation have been well reported, with an overall complication rate of<2%. However, a paucity of high-powered, real-world data is available on the thrombotic outcomes of nonthermal techniques. In the present study, we compared the incidence of endovenous heat-induced thrombosis (EHIT) and endovenous glue-induced thrombosis (EGIT) in a large cohort of patients with CVI.

A retrospective review was conducted at two tertiary-level institutions of patients who had undergone superficial endovenous ablation from 2018 to 2021. AZD5438 The patient demographics, comorbidities, and periprocedural outcomes were collected through medical record revithermal techniques was performed. A univariate analysis of the risk factors for EHIT and EGIT revealed no significant factors predisposing to thrombotic events.

The results from the present study have demonstrated the safety of RFA and CAG closure techniques for CVI, with lower thrombotic rates than previously reported. Further work might help to identify how these results can be achieved across all venous ablative techniques for CVI, even for patient populations with advanced venous disease and possibly a greater than average risk of thrombotic events.

In the present study, we evaluated the technical and clinical outcomes of thoracic central vein reconstruction for superior vena cava (SVC) syndrome using kissing Viabahn VBX stent grafts (W.L. Gore & Associates, Flagstaff, AZ).

All adult patients with SVC syndrome who had undergone attempted bilateral brachiocephalic vein-to-SVC reconstruction using kissing VBX stent grafts at an academic hospital between August 2019 and February 2021 were reviewed. The technical results, adverse events, imaging follow-up findings, and clinical outcomes were recorded. Patency over time was assessed using Kaplan-Meier analysis.

A total of 28 patients (16 women and 12 men; mean age, 52.0years) constituted the study cohort. Of the 28 patients, 17 (60.7%) had had benign and 11 (39.3%) malignant etiologies. The presenting symptoms included neck swelling (n= 17; 60.7%), bilateral upper extremity swelling (n= 15; 53.6%), dyspnea (n= 7; 25%), unilateral upper extremity swelling (n= 4; 14.3%), and dysphagia (n= 1; 3.6%). SVcic central vein reconstruction with kissing VBX stent grafts was feasible with a high rate of symptom resolution and acceptable patency. However, this technique should not be recommended for those with benign SVC syndrome owing to the high risk of cardiac tamponade.Immunosuppressive tumor microenvironment (ITM), poor immunogenicity, and low tumor penetration markedly reduce the capability of tumor immunotherapy. To address these challenges, we successfully engineered acidity-triggered nanoparticles (NPs) with size reduction and charge switchable features to boost tumor immunotherapy based on indoleamine 2,3-dioxygenase 1 siRNA (IDO1 siRNA) and immunogenic cell death (ICD). The NPs significantly augmented tumor penetrating ability and improved cellular uptake via the detachment of 2,3-dimethylmaleic anhydride-grafted poly(ethylene glycol)-poly(L-lysine) copolymer (mPEG-PLL-DMA, PLM) from large-sized NPs with a negative charge. Subsequently, the NPs with a positive charge and small size rapidly escaped from the lysosomes and released mitoxantrone (MIT) and IDO1 siRNA. The antitumor immune response of IDO1 siRNA and MIT provided good antitumor capability by enhancing DC maturation, improving the number of CTLs, and downregulating the level of Tregs in tumor tissues. In sumCTLs, and downregulating the level of Tregs in tumor tissues. Thus, the NPs showed a promising pathway against aggressive and difficult-to-treat cancers.Antibiotics may trigger alterations in mitochondrial function, which has been explored in cells culture, and in animal model of sepsis. This study sought to evaluate whether antibiotic therapy affects mitochondrial bioenergetics in a 68-patients clinical study. We studied mitochondrial respiratory rates at two time points the first day of antibiotic administration and three days after. The Δbasal, ΔCI, ΔCII respiration, and ΔBCE respiratory rates were not different between patients administered with polymyxin, vancomycin, amoxicillin-clavulanate, and azithromycin compared to those who were not administered. Specific beta-lactams are associated with specific modifications in mitochondrial respiratory endpoints - patients who used meropenem had higher delta C2 values compared to those who did not (p = 0.03). Patients who used piperacillin-tazobactam had lower delta C1 (p = 0.03) values than those who did not, but higher delta C2 values (p = 0.02). These mitochondrial metabolic signatures in isolated lymphocytes challenges the proposed effects of antibiotics in mitochondrial bioenergetics of cell cultures, but at current status have an uncertain clinical significance.Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) continues to impact our lives by causing widespread illness and death and poses a threat due to the possibility of emerging strains. SARS-CoV-2 targets angiotensin-converting enzyme 2 (ACE2) before entering vital organs of the body, including the brain. Studies have shown systemic inflammation, cellular senescence, and viral toxicity-mediated multi-organ failure occur during infectious periods. However, prognostic investigations suggest that both acute and long-term neurological complications, including predisposition to irreversible neurodegenerative diseases, can be a serious concern for COVID-19 survivors, especially the elderly population. As emerging studies reveal sites of SARS-CoV-2 infection in different parts of the brain, potential causes of chronic lesions including cerebral and deep-brain microbleeds and the likelihood of developing stroke-like pathologies increases, with critical long-term consequences, particularly for individuals with neuropathological and/or age-associated comorbid conditions.
