Based on the results of this study, which assesses the outcomes of patients who underwent cone repairs with surgical modifications, we argue that right ventricular oblique plication, tricuspid valve delamination, surgical valve rotation, and tricuspid ring annuloplasty protect valve coaptation and function in the early and midterm, thereby having beneficial effects on right ventricle remodeling.

Treatment for Boxers with ventricular tachycardia (VT) is limited. Electroanatomic mapping (EAM) facilitates identification of arrhythmogenic substrate for radiofrequency catheter ablation (RFCA).
Describe the use of EAM to guide RFCA in Boxers with VT.
Five client-owned Boxers with symptomatic VT or persistent VT despite antiarrhythmic medications.
Case series evaluating clinical, EAM, and before and after RFCA Holter data.
Sustained VT was inducible in 3 dogs, but required aggressive stimulation protocols. Low-voltage areas consistent with electroanatomic scar were found in 2 dogs, located at the right ventricular (RV) outflow tract and cranial RV. Two dogs had a focal activation pattern of VT and 1 dog had a reentrant mechanism. After RFCA, all dogs no longer collapsed and had fewer runs of VT, 3 of which had 0 runs of VT. Number of ventricular premature beats increased in 3 dogs and decreased in 2 dogs, 1 of which had nearly complete resolution of all arrhythmias. Procedural complications included ventricular fibrillation (n=2) with successful defibrillation, bruising or hemorrhage at the vascular access site (n=4), retroperitoneal hemorrhage (n=1), aortic and mitral regurgitation (n=1), onset of frequent supraventricular tachycardia (n=1), and persistent right pelvic limb lameness (n=1).
Electroanatomic mapping and RFCA are feasible in Boxers with VT. Based on this small cohort, RFCA may help decrease runs of VT and improve clinical signs. The anatomic substrate and electrophysiologic mechanisms are variable and require further study.

In hospital settings, decisions about potentially life-prolonging treatments are often made in a dialogue between a patient and their physician, with a focus on active treatment. Nurses can have a valuable contribution in this process, but it seems they are not always involved. Our aim was to explore how hospital nurses perceive their current role and preferred role in shared decision-making about potentially life-prolonging treatment in patients in the last phase of life.
Cross-sectional quantitative study conducted in the Netherlands in April and May 2019.
An online survey, using a questionnaire consisting of 12 statements on nurses' opinion about supporting patients in decisions about potentially life-prolonging treatments, and 13 statements on nurses' actual involvement in these decisions.
In total 179 hospital nurses from multiple institutions who care for adult patients in the last phase of life responded. Nurses agreed that they should have a role in shared decision-making about potentially lifysicians and patients, though involvement is still not common. Future research should focus on strategies, such as training programs, that empower nurses to take an active role in decision-making.
To explore Registered Nurses' approaches to pressure injury prevention, including how they perceive their roles, how they prioritize pressure injury prevention and factors influencing prevention in the Chinese context.
A qualitative descriptive study.
Audio-recorded, face-to-face, semi-structured individual interviews were conducted with Registered Nurses in a large tertiary hospital in China from August to December 2020. Using the System Engineering Initiative for Patient Safety Model, the interview guide was developed to describe the work system, processes and outcomes (three domains) associated with nurses' pressure injury prevention practices. Deductive and inductive content analyses were used.
Twenty-seven nurses participated in the interviews. Four themes related to two domains of the model emerged Work system (i) Nurses lead and coordinate pressure injury prevention; Work processes (ii) Individualized pressure injury prevention is founded on comprehensive patient assessment; (iii) Collaboratingxperts. Acknowledging nurses leading role in prevention and ensuring they have adequate resources are important for quality care.
Pressure injury prevention is primarily a nursing responsibility therefore nurses' approaches to prevention were explored. Nurses rely on collaboration with others and access to various resources to provide pressure injury prevention. They recognize the patients' and carers' roles and acknowledge the importance of accessing guidance and support from nursing leaders and wound experts. Acknowledging nurses leading role in prevention and ensuring they have adequate resources are important for quality care.Conservation professionals use language related to instrumental, intrinsic, and relational values when communicating about the importance of conservation, frequently in connection with ecosystem services. However, few researchers have examined whether messages that emphasize values associated with ecosystem services result in different policy-support or behavior-change outcomes among different audiences. We conducted a large-scale survey experiment with participants (n = 815) who resided in the United States and were recruited online via the survey platform Qualtrics. The experiment tested whether messages about watershed protection that emphasize instrumental, intrinsic, or relational values (as opposed to the information-only control message) resulted in differing support for policies or behavioral intentions related to watershed conservation. Respondents' personal characteristics had a stronger effect on conservation beliefs than the way values were framed (i.e., than treatments in the experiment). For example, income positively predicted policy support (β = 0.07, 95% CI 0.02-0.12, p = 0.01, corrected p = 0.03). Instrumental messages decreased (SSG, tense) policy support among people who identified as politically liberal (β = -0.75, 95% CI -1.19 to -0.30, p = 0.001, corrected p = 0.003). Epigenetics inhibitor Over 40% of respondents selected relational values over other value types as the main reason to protect watersheds. Our results demonstrated that political orientation interacts with how the importance of conservation is framed in complex ways and that conservation practitioners might improve the effectiveness of their communications by incorporating relational values and tailoring messages to different audiences.Ammonia nitrogen is a major pollutant that causes great physiological harm to crustaceans in culture. In this study, we conducted a 28 day chronic ammonia nitrogen stress experiment with broodstock populations (Dianshan, DS) and hybrid offspring populations (DS ♀ × CD (Changjiang ♂ × Dongting ♀), SCD) exposed to 0, 1 and 10 mg/L of ammonia concentrations. A 28 day feeding trial and chronic ammonia nitrogen stress were used to investigate the effects on the growth performance, histological structure and lipid metabolism of juvenile shrimp, Macrobrachium nipponense. Our results indicated that survival rates in the SCD groups were significantly higher than those in the DS groups, whereas weight and length gain rates were not significantly different between the groups (p > 0.05). Histological structure results showed that the number of vacuoles in the DS group was significantly higher than that in the SCD group and hepatopancreas cell structures were disrupted in the ammonia treatment groups. The results of oil red staining showed that the number of lipid droplets increased significantly with the increase in ammonia concentration. As the ammonia concentration increased, fatty acid contents, lipid enzyme activities and lipid metabolism-related gene expression all tended to rise. In conclusion, ammonia nitrogen exposure caused damage to the hepatopancreas structure of juvenile shrimp and disturbed the lipid metabolism of the hepatopancreas. In addition, the SCD population had stronger stress resistance than the DS population when subjected to the same concentration of ammonia nitrogen stress.
Among subtypes of chronic inflammatory demyelinating polyneuropathy (CIDP), different immune pathophysiologies have been proposed. In this study, sensory nerve conduction studies were compared among clinical subtypes to attempt to better understand the underlying pathophysiology.
A total of 138 patients with CIDP was classified into clinical subtypes typical CIDP (N=68), multifocal CIDP (N=27), or other (N=2). Patients with immunoglobulin M (IgM) neuropathy anti-myelin-associated glycoprotein neuropathy (MAG; N=19) were also included as disease controls. Sensory nerve action potentials (SNAPs) were recorded in the median, ulnar, and superficial radial and sural nerves.
SNAP amplitudes (P < .05) and conduction velocities (P < .01) in the median nerve and conduction velocities (P < .05) in the ulnar nerve were lower in typical CIDP than in multifocal CIDP, whereas those in the radial and sural nerves were comparable in each group. Low median and normal sural SNAP amplitudes were more common in typical CIDP (P < .005) than in multifocal CIDP, suggesting predominant involvement at terminal portions of the nerves.
Terminal portions of sensory nerves are preferentially affected in typical CIDP compared with multifocal CIDP. These findings might be partially explained by the hypothesis of antibody-mediated demyelination in typical CIDP at the regions where the blood-nerve barrier is anatomically deficient, whereas multifocal CIDP predominantly affects the nerve trunks, largely due to cell-mediated demyelination, with disruption of the blood-nerve barrier.

In some physiological states, cells rely on ketone bodies to satisfy their metabolic needs, especially during nutrient stress. Here, we show that PDA cells can activate ketone body metabolism and that β-hydroxybutyrate (βOHB) is an alternative cell-intrinsic or systemic fuel that can promote PDA growth and progression. PDA cells activate enzymes required for ketogenesis, utilizing various nutrients as carbon sources for ketone body formation. By assessing metabolic gene expression from spontaneously arising PDA tumors in mice, we find HMG-CoA lyase (HMGCL), involved in ketogenesis, to be among the most deregulated metabolic enzymes in PDA compared to normal pancreas. In vitro depletion of HMGCL impedes migration, tumor cell invasiveness, and anchorage-independent tumor sphere compaction. Moreover, disrupting HMGCL drastically decreases PDA tumor growth in vivo, while βOHB stimulates metastatic dissemination to the liver.
