We Should Not Get Rid of Incivility Online
This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.Incivility and toxicity have become concepts du jour in research about social media. The clear normative implication in much of this research is that incivility is bad and should be eliminated. Extensive research—including some that we’ve authored—has been dedicated to finding ways to reduce or eliminate incivility from online discussion spaces. In our work as part of the Civic Signals Initiative, we’ve been thinking carefully about what metrics should be adopted by social media platforms eager to create better spaces for their users. When we tell people about this project, removing incivility from the platforms frequently comes up as a suggested metric. In thinking about incivility, however, we’ve become less convinced that it is desirable, or even possible, for social media platforms to remove all uncivil content. In this short essay, we discuss research on incivility, our rationale for a more complicated normative stance regarding incivility, and what other orientations may be more useful. We conclude with a post mortem arguing that we should not abandon research on incivility altogether, but we should recognize the limitations of a concept that is difficult to universalize
Current techniques in adult-acquired buried penis repair: where are we now
Adult-acquired buried penis (AABP) is a condition associated with penile entrapment, penile shaft skin loss, and an enlarged pannus which engulfs the penis. The increased prevalence, awareness, and availability of surgical repair have led to a relative standardization in repairs. The surgical approach to AABP has evolved from a lengthy procedure with extended inpatient stay to one that may be done in an outpatient setting. The critical steps for surgical management of AABP have remained largely consistent over time, including: release of the penis with removal of diseased skin, suprapubic and/or abdominal panniculectomy, and skin coverage (usually with grafts). In contrast, the finer points of the procedure and perioperative care have undergone evolution. The aim of our approach was to optimize postoperative aesthetic and functional outcomes. Our perioperative management was modeled after enhanced recovery after surgery principles to minimize morbidity and expedite recovery. There remains room for improvement in the care of individuals with AABP, specifically multi-institutional collaboration, development of disease-specific outcome measures, and standardization of treatment algorithms
Treatment effect of neoadjuvant endocrine therapy compared to neoadjuvant chemotherapy on breast cancer outcomes.
Oxidant-induced apoptosis is mediated by oxidation of the actin-regulatory protein cofilin.
Physiological oxidants that are generated by activated phagocytes comprise the main source of oxidative stress during inflammation. Oxidants such as taurine chloramine (TnCl) and hydrogen peroxide (H(2)O(2)) can damage proteins and induce apoptosis, but the role of specific protein oxidation in this process has not been defined. We found that the actin-binding protein cofilin is a key target of oxidation. When oxidation of this single regulatory protein is prevented, oxidant-induced apoptosis is inhibited. Oxidation of cofilin causes it to lose its affinity for actin and to translocate to the mitochondria, where it induces swelling and cytochrome c release by mediating opening of the permeability transition pore (PTP). This occurs independently of Bax activation and requires both oxidation of cofilin Cys residues and dephosphorylation at Ser 3. Knockdown of endogenous cofilin using targeted siRNA inhibits oxidant-induced apoptosis, which is restored by re-expression of wild-type cofilin but not by cofilin containing Cys to Ala mutations. Exposure of cofilin to TnCl results in intramolecular disulphide bonding and oxidation of Met residues to Met sulphoxide, but only Cys oxidation causes cofilin to induce mitochondrial damage
Living with Advanced Breast Cancer: A Descriptive Analysis of Survivorship Strategies
Survivors of advanced breast cancer (ABC), also known as metavivors, are often left with fewer treatment options in the landscape of a cure culture. Metavivors have unique psychosocial and physical needs distinct from patients with early-stage breast cancer. This analysis delves into side effects commonly experienced by patients with ABC, such as fatigue, anxiety, and cardiotoxicity; how these side effects impact caregiver support, financial toxicity, emotional strain, and spiritual and emotional distress; as well as current strategies for mitigation, including nutrition, exercise, and participation in clinical research. Overall, this analysis is a mandate for additional research to explore novel treatments and implement strategies to maintain and improve patients’ quality of life
