"I feel like I'm walking on eggshells": a qualitative study of moral distress among Chinese emergency doctors.

BACKGROUND: While the number of emergency patients worldwide continues to increase, emergency doctors often face moral distress. It hampers the overall efficiency of the emergency department, even leading to a reduction in human resources. AIM: This study explored the experience of moral distress among emergency department doctors and analyzed the causes of its occurrence and the strategies for addressing it. METHOD: Purposive and snowball sampling strategies were used in this study. Data were collected through in-depth, semi-structured interviews with 10 doctors working in the emergency department of a tertiary general hospital in southwest China. The interview data underwent processing using the Nvivo 14 software. The data analysis was guided by Colaizzi's phenomenological analysis method. STUDY FINDINGS: This study yielded five themes: (1) imbalance between Limited Medical Resources and High-Quality Treatment Needs; (2) Ineffective Communication with Patients; (3) Rescuing Patients With no prospect of treatment; (4) Challenges in Sustaining Optimal Treatment Measures; and (5) Strategies for Addressing Moral Distress. CONCLUSION: The moral distress faced by emergency doctors stems from various aspects. Clinical management and policymakers can alleviate this distress by enhancing the dissemination of emergency medical knowledge to the general public, improving the social and economic support systems, and strengthening multidisciplinary collaboration and doctors' communication skills.

Black necrosis of the glans penis associated with calciphylaxis: A case report.

RATIONALE: Calciphylaxis, known as calcific uremic arteriolopathy, is a rare cause of dry gangrene. Despite an increase in the clinical recognition of demographic characteristics and risk factors associated with calciphylaxis, it remains a poorly understood disease with high mortality. PATIENT CONCERNS AND DIAGNOSES: We present a 45-year-old man, who was diagnosed with calciphylaxis disease, with a history of diabetes mellitus, end-stage renal disease and cirrhosis with a half-month evolution of painful dry gangrene on his glans penis and scrotum. The patient also presented with gangrene of fingers. INTERVENTIONS AND OUTCOMES: The patient and his family opted for palliative care. However, he died eventually. LESSONS: This case contributed to the current understanding of calciphylaxis. Since no standard treatment is available and the prognosis remained poor, early, and accurate diagnosis of calciphylaxis is important. We here report the current case and provide data for the diagnosis and treatment of this kind of disease.

Co-administration of N-acetylcysteine and dexmedetomidine plays a synergistic effect on protection of LPS-induced acute lung injury via correcting Th1/Th2/Th17 cytokines imbalance.

Recently both N-acetylcysteine (NAC) and Dexmedetomidine (DEX) have shown emerging roles in protection of acute lung injury (ALI). However, how their protective roles work and whether they can provide synergistic effects in ALI remain unknown. Here we explored it from the hot research viewpoint of Th1/Th2/Th17 cytokines balance. Lipopolysaccharide (LPS)-induced ALI was established and treated with NAC and/or DEX. Mice were divided into Sham group, ALI group, NAC group, DEX group and NAC+DEX group. Mice were sampled at 6, 12 and 24 hours after the model construction. Histopathology, wet to dry ratio and myeloperoxidase (MPO) activity were assessed in lung tissues. Protein concentration and cell count were assessed in bronchoalveolar lavage fluid (BALF). Th1/Th2/Th17 cytokines were assessed in plasma, BALF and lung homogenate. ALI-induced lung morphological damage, edema and aberrant MPO activity can be attenuated by NAC or DEX and mostly by NAC+DEX. NAC with DEX significantly reduced ALI-induced protein leakage and cell infiltration in BALF. Th1/Th2/Th17 cytokines imbalance aggravated with ALI progression. NAC, DEX and especially NAC+DEX can effectively correct these unbalanced cytokines. Galectin-9 and Tim-3 were transcriptionally up-regulated in ALI. Combination of NAC with DEX obtained a maximum effect on decreasing Galectin-9/Tim-3 expression. In summary, Th1/Th2/Th17 cytokines imbalance is newly found to participate in LPS-induced ALI. NAC or DEX administration can attenuate ALI by rebalancing Th1/Th2/Th17 cytokines. Their protective roles can be enhanced when co-administration, because DEX may relieve the Galectin-9/Tim-3 axis-mediated immune suppression.
