RESUMO

BACKGROUND: A culture centered on relationships and communication is necessary to improve the quality of life of older adults living in nursing homes. OBJECTIVES: To examine the effects of a storytelling program by examining the cognitive, emotional, and psychosocial changes in older adults in facilities and explore staff experience of changes in care. METHODS: This mixed method study delivered a 6-week storytelling program based on relationship-centered care for residents of nursing homes (aged >65 years). Changes in emotional expression, depression, communication skills, social support, interpersonal relationships, nurse-patient interaction, and the person-centered environment as perceived by older adults were quantitatively analyzed using pre-intervention and post-intervention surveys. Qualitative data were collected through weekly stories created by residents, followed by focus group interviews with nursing home staff, analyzed using reflexive thematic analysis to enhance understanding of the program's outcomes. RESULTS: The 42 residents reported significant changes in their emotional expression, depression, communication skills, social support, interpersonal relationships, nurse-patient interaction, and person-centered environment scores after the 6-week intervention. Analysis of the residents' stories identified 5 themes. The staff focus group interviews identified 2 themes and 7 subthemes. Intervention group residents were more likely to initiate conversations, express themselves, carefully observe themselves and others, and actively participate in social activities. CONCLUSIONS: The storytelling program was useful in reducing older adults' negative emotions by allowing them to express their thoughts and feelings and improve their relationships, creating opportunities for social interaction. These effects could help foster relationship- and communication-centered facility cultures.

RESUMO

BACKGROUND: Holistic housing renovations combine physical housing improvements with social and socioeconomic interventions (e.g. referral to social services, debt counselling, involvement in decision-making, promoting social cohesion). In a deprived neighbourhood in Utrecht, the Netherlands, this paper examined residents' and professionals' experiences, ideas, and perceptions regarding holistic housing renovation, its health effects, and underlying mechanisms explaining those effects. METHODS: Semi-structured in-depth interviews were conducted with 21 social housing residents exposed to holistic housing renovation, and 12 professionals involved in either the physical renovation or social interventions implemented. Residents were interviewed in various renovation stages (before, during, after renovation). Transcripts were deductively and inductively coded using qualitative software. RESULTS: Residents experienced and professionals acknowledged renovation stress caused by nuisance from construction work (noise, dust), having to move stuff around, and temporary moving; lack of information and control; and perceived violation of privacy. Involvement in design choices was appreciated, and mental health improvement was expected on the long term due to improved housing quality and visual amenity benefits. Social contact between residents increased as the renovation became topic for small talk. Few comments were made regarding physical health effects. The interviews revealed a certain amount of distrust in and dissatisfaction with the housing corporation, construction company, and other authorities. CONCLUSIONS: Renovation stress, aggravated by lack of information and poor accessibility of housing corporation and construction company, negatively affects mental health and sense of control. Potential stress relievers are practical help with packing and moving furniture, and increased predictability by good and targeted communication. Social interventions can best be offered after renovation, when residents live in their renovated apartment and the nuisance and stress from the renovation is behind them. Social partners can use the period leading up to the renovation to show their faces, offer practical help to reduce renovation stress, and increase residents' trust in their organization and authorities in general. This might also contribute to residents' willingness to accept help with problems in the social domain after renovation.

RESUMO

Idiopathic severe aplastic anemia (SAA) is a disease of bone marrow failure caused by T-cell-induced destruction of hematopoietic stem and progenitor cells (HSPCs), however the mechanism remains unclear. We performed single-cell RNA sequencing of PBMCs and BMMCs from SAA patients and healthy donors and identified a CD8+ T cell subset with a tissue residency phenotype (Trm) in bone marrow that exhibit high IFN-γ and FasL expression and have a higher ability to induce apoptosis in HSPCs in vitro through FasL expression. CD8+ Trm cells were induced by IL-15 presented by IL-15Rα on monocytes, especially CD16+ monocytes, which were increased in SAA patients. CD16+ monocytes contributed to IL-15-induced CD38+CXCR6+ pre-Trm differentiation into CD8+ Trm cells, which can be inhibited by the CD38 inhibitor 78c. Our results demonstrate that IL-15-induced CD8+ Trm cells are pathogenic cells that mediate HSPC destruction in SAA patients and are therapeutic targets for future treatments.

RESUMO

Receptors controlling the cross-presentation of tumor antigens by macrophage subsets in cancer tissues are poorly explored. Here, we show that TIM4+ large peritoneal macrophages efficiently capture and cross-present tumor-associated antigens at early stages of peritoneal infiltration by ovarian cancer cells. The phosphatidylserine (PS) receptor TIM4 promotes maximal uptake of dead cells or PS-coated artificial targets and triggers inflammatory and metabolic gene programs in combination with cytoskeletal remodeling and upregulation of transcriptional signatures related to antigen processing. At the cellular level, TIM4-mediated engulfment induces nucleation of F-actin around nascent phagosomes, delaying the recruitment of vacuolar ATPase, acidification, and cargo degradation. In vivo, TIM4 deletion blunts induction of early anti-tumoral effector CD8 T cells and accelerates the progression of ovarian tumors. We conclude that TIM4-mediated uptake drives the formation of specialized phagosomes that prolong the integrity of ingested antigens and facilitate cross-presentation, contributing to immune surveillance of the peritoneum.

RESUMO

Purpose: Burnout is an occupational stress syndrome that gives rise to emotional exhaustion (EE) depersonalization (DP) and reduced personal accomplishment (PA). Increasing rates of burnout among health care professionals has been reported globally. Saudi Arabia appears to be among the highest in prevalence with reports of higher than 70%. Medical residents in training are the highest group at risk. The literature has repeatedly linked burnout among residents with poor academic performance on training exams, impaired quality of life, career choice regret and intentions to abandon medicine. In this study, we explore the factors that contribute to resident burnout, their experiences with burnout and how they choose to mitigate it. Methods: A qualitative design was used to conduct this study in the city of Riyadh, Saudi Arabia. A total of 14 residents from surgical and non-surgical programs were interviewed through in-depth interviews. Interpretive thematic analysis was used in coding and generated coding templates. Categories were repetitively reviewed and revised, expanding to include new data as it emerged and collapsing to remove redundant codes. Categories were organized into the final themes and sub-themes. Results: All participants demonstrated a shared thread of shame in reaching the level of burnout. Three main interlinked themes were identified: Burnout stigma cycle, amalgamated causes of burnout and self-coping with burnout. One of the concerning findings in our study is the participants' pursuit of self-coping strategies and the avoidance of formal help, creating a cycle of suffering in silence. Conclusion: The literature has repeatedly reported high levels of burnout among residents in training. This study has added another dimension to those findings through the exploration of residents actual accounts and appears to link burnout with suboptimal training and working conditions. We have highlighted the pivotal role stigma and shame play in completely preventing residents from seeking professional help.

RESUMO

BACKGROUND: While communication is an essential skill for providing effective medical care, it is infrequently taught or directly assessed, limiting targeted feedback and behavior change. We sought to evaluate the impact of a multi-departmental longitudinal residency communication coaching program. We hypothesized that program implementation would result in improved confidence in residents' communication skills and higher-quality faculty feedback. METHODS: The program was implemented over a 3-year period (2019-2022) for surgery and neurology residents at a single institution. Trained faculty coaches met with assigned residents for coaching sessions. Each session included an observed clinical encounter, self-reflection, feedback, and goal setting. Eligible residents completed baseline and follow-up surveys regarding their perceptions of feedback and communication. Quantitative responses were analyzed using paired t-tests; qualitative responses were analyzed using content analysis. RESULTS: The baseline and follow-up survey response rates were 90.0% (126/140) and 50.5% (46/91), respectively. In a paired analysis of 40 respondents, residents reported greater confidence in their ability to communicate with patients (inpatient: 3.7 vs. 4.3, p < 0.001; outpatient: 3.5 vs. 4.2, p < 0.001), self-reflect (3.3 vs. 4.3, p < 0.001), and set goals (3.6 vs. 4.3, p < 0.001), as measured on a 5-point scale. Residents also reported greater usefulness of faculty feedback (3.3 vs. 4.2, p = 0.001). The content analysis revealed helpful elements of the program, challenges, and opportunities for improvement. Receiving mentorship, among others, was indicated as a core program strength, whereas solving session coordination and scheduling issues, as well as lowering the coach-resident ratio, were suggested as some of the improvement areas. CONCLUSIONS: These findings suggest that direct observation of communication in clinical encounters by trained faculty coaches can facilitate long-term trainee growth across multiple core competencies. Future studies should evaluate the impact on patient outcomes and workplace-based assessments.

RESUMO

To investigate the protective role of immune response gene 1 (IRG1) and exogenous itaconate in autoimmune hepatitis (AIH) and elucidate the underlying mechanisms. Wild-type and IRG1-/- AIH mouse models were established, and samples of liver tissue and ocular blood were collected from each group of mice to assess the effects of IRG1/itaconate on the expression of pro- and anti-inflammatory cytokines. The levels of liver enzymes and related inflammatory factors were determined using enzyme-linked immunosorbent assay and real-time quantitative polymerase chain reaction (PCR). Liver histomorphology was detected through hematoxylin and eosin staining and then scored for liver injury, and the infiltration levels of tissue-resident memory T (TRM) cells and related molecules in the liver tissue were detected through immunofluorescence staining in vitro. RNA sequencing and gene enrichment analysis were conducted to identify the corresponding molecules and pathways, and lentiviral transfection was used to generate TRM cell lines with IRG1, Jak3, Stat3, and p53 knockdown. Real-time quantitative PCR and western blot were performed to detect the expression levels of relevant mRNAs and proteins in the liver tissue and cells. The percentage of apoptotic cells was determined using flow cytometry. IRG1/itaconate effectively reduced the release of pro-inflammatory cytokines and the pathological damage to liver tissue, thereby maintaining normal liver function. At the same time, IRG1/itaconate inhibited the JAK3/STAT3 signaling pathway, regulated the expression of related downstream proteins, and inhibited the proliferation and promoted the apoptosis of CD69+CD103+CD8+ TRM cells. For the first time, P53 was found to act as a downstream molecule of the JAK3/STAT3 pathway and was regulated by IRG1/itaconate to promote the apoptosis of CD8+ TRM cells. IRG1/itaconate can alleviate concanavalin A-induced autoimmune hepatitis in mice by inhibiting the proliferation and promoting the apoptosis of CD69+CD103+CD8+ TRM cells via the JAK3/STAT3/P53 pathway.

RESUMO

Zhen-Wu-Tang (ZWT), a conventional herbal mixture, has been recommended for treating lupus nephritis (LN) in clinic. However, its mechanisms of action remain unknown. Here we aimed to define the immunological mechanisms underlying the effects of ZWT on LN and to determine whether it affects renal tissue-resident memory T (TRM) cells. Murine LN was induced by a single injection of pristane, while in vitro TRM cells differentiated with IL-15/TGF-ß. We found that ZWT or mycophenolate mofetil treatment significantly ameliorated kidney injury in LN mice by decreasing 24-h urine protein, Scr and anti-dsDNA Ab. ZWT also improved renal pathology and decreased IgG and C3 depositions. In addition, ZWT down-regulated renal Desmin expression. Moreover, it lowered the numbers of CD8+ TRM cells in kidney of mice with LN while decreasing their expression of TNF-α and IFN-γ. Consistent with in vivo results, ZWT-containing serum inhibited TRM cell differentiation induced by IL-15/TGF-ß in vitro. Mechanistically, it suppressed phosphorylation of STAT3 and CD122 (IL2/IL-15Rß)expression in CD8+ TRM cells. Importantly, ZWT reduced the number of total F4/80+CD11b+ and CD86+, but not CD206+, macrophages in the kidney of LN mice. Interestingly, ZWT suppressed IL-15 protein expression in macrophages in vivo and in vitro. Thus, we have provided the first evidence that ZWT decoction can be used to improve the outcome of LN by reducing CD8+ TRM cells via inhibition of IL-15/IL-15R /STAT3 signaling.

RESUMO

BACKGROUND: To investigate the role of CD47 expression and its relationship with tumor-resident macrophages, specifically at the tumor margin, in patients with type II endometrial cancer. This study aims to elucidate whether CD47 could serve as a prognostic marker and to understand the dynamics between CD47 and macrophages, which could inform new therapeutic strategies. METHODS: A retrospective cohort study was conducted involving 75 patients of type II endometrial. Immunohistochemical analysis was performed to assess CD47 expression and macrophage markers (CD68 and CD163). RESULTS: The study found no direct correlation between CD47 expression levels and overall survival (p = 0.32), challenging its role as an independent prognostic marker in type II endometrial cancer. The higher expression of CD47 had significantly less incidence of endometrioid carcinoma G3 (p = 0.047). The negative correlation between CD47 H-score and the density of CD68-positive macrophages at tumor margin was statistically significant (p = 0.049). A high density of CD68-positive macrophages at the tumor margin but a low density of CD163-positive macrophages at the tumor margin were associated with poorer prognosis (p = 0.036). CONCLUSIONS: The complex interaction between CD47 and macrophages, particularly at the tumor margin, suggests new avenues for targeted therapy in type II endometrial cancer.

RESUMO

Social restrictions during the pandemic required creative solutions for incorporating interns into a demanding residency, building relationships, and fostering resiliency. We hypothesized that resident-driven initiatives focused on inclusion would overcome a lack of in-person events. An anonymous survey was administered to all surgery residents to assess burnout pre- and post-wellness interventions. Assessment scores were analyzed with Mann-U Whitney and Kruskal-Wallis tests. The surveys were completed by 71.6% (n = 53) and 48.6% (n = 36) of residents, respectively, and demonstrated high metrics for wellness measures. There were no significant differences on the 6-month post-assessment, suggesting interventions preserved high ratings. The PGY1 subgroup demonstrated improvement in the ability to identify a faculty mentor (P < .01) and had reduced burnout measures (P < .05). Surgical resident wellness is not dependent on department-wide gatherings; rather, resident-driven interventions in the workspace and intimate social support demonstrated an impact on wellness and reduced burnout.

RESUMO

Cardiac resident macrophages (CRMs) are the main population of cardiac immune cells. The role of these cells in regeneration, functional remodeling, and repair after cardiac injury is always the focus of research. However, in recent years, their dynamic changes and contributions in physiological states have a significant attention. CRMs have specific phenotypes and functions in different cardiac chambers or locations of the heart and at different stages. They further show specific differentiation and development processes. The present review will summarize the new progress about the spatiotemporal distribution, potential developmental regulation, and their roles in cardiac development and aging as well as the translational potential of CRMs on cardiac diseases. Of course, the research tools for CRMs, their respective advantages and disadvantages, and key issues on CRMs will further be discussed.

RESUMO

BACKGROUND: Despite widespread efforts to combat the opioid epidemic, an ongoing contributor to opioid misuse remains post-operative opioid overprescribing by residents. The goal of this study was to evaluate the impact of a low-cost, reproducible "just in time" intervention on opioid prescribing in dialysis access operations. METHODS: Standardized opioid prescribing guidelines were emailed to residents on the vascular service on the first day of the rotation. Opioid prescriptions were reviewed for four years before and one year after this intervention. Wilcoxon rank-sum test and tests of proportions were used to compare groups. RESULTS: Overall, 299 patients underwent dialysis access procedures. There was a decrease in patients discharged with opioids following the intervention from 58% to 36% (p â€‹= â€‹0.003). For patients prescribed opioids, the median quantity decreased from 90 to 45 oral morphine equivalents (p â€‹= â€‹0.03). CONCLUSIONS: This low-cost and timely learning intervention may be a useful adjunct to reduce post-operative opioid prescriptions.

RESUMO

Background This pilot study aims to examine the effectiveness of a spinal cord stimulator (SCS) simulator training system in improving the confidence of pain fellows in SCS placement. Methodology Five Ukrainian physicians (neurologists, neurosurgeons, and an anesthesiologist) completed a 10-item survey regarding their confidence in various aspects of SCS placement and their opinions on how effective SCS models were for educational purposes. After placing SCS leads using the SCS simulator, the physicians took the same survey again. The Mann-Whitney U test was used to determine if there was a significant difference in total scores pre and post-simulator training. The software PAST (PAleontological STatistics) was used for statistical analysis. Results Overall, five participants had a 38% statistically significant increase in survey scores before and after the intervention (mean: 4.2 vs. 6.2, p = 0.0055). With regards to each item of the survey, participants had a significantly increased confidence in driving leads (2.6 vs. 5.2, p = 0.008) and in overall technical skills for the SCS procedure after the training (2.8 vs. 5.2, p = 0.0188). Although the other eight survey items were not statistically significant (p > 0.05), participants had a 28% increase in confidence when inserting epidural needles, a 20% increase in interpreting simulated X-rays, a 32% increase in navigating challenging anatomical variations, a 12% increase in identifying key anatomical landmarks, a 20% increase in ensuring the correct placement of the lead, or a 53% increase in preparedness for performing an SCS procedure in a real clinical setting. The participant's perspective on how valuable the stimulator training was for enhancing procedural skills increased by 38% and how well the simulator replicated real-life SCS procedure increased by 52%, although both were statistically insignificant (p > 0.05). Conclusions This pilot study shows that the utilization of simulated neuromodulation training is a viable means of augmenting neuromodulation education by increasing physician's confidence in aspects of the SCS placement procedure. The extent to which simulator training improves procedural skills in a real-life SCS placement needs to be investigated further.

RESUMO

Objective: The process of resident recruitment is costly, and our surgical residency program expends significant time on the resident selection process while balancing general duties and responsibilities. The aim of our study was to explore the relationship between otolaryngology-head and surgery (OHNS) residents' National Residency Matching Program (NRMP) rank-list position at our institution and their subsequent residency performance. Study Design: Retrospective cohort study. Setting: Single site institution. Methods: We retrospectively reviewed 7 consecutive resident classes (2011-2017) at a single tertiary OHNS residency program. We reviewed each resident's absolute rank order in the NRMP matches. Measures of residency performance included overall faculty evaluation during postgraduate year 5 (PGY5), annual in-service examination scores (scaled score), and the number of manuscripts published in peer-reviewed journals. Correlations between NRMP rank order and subsequent residency performance were assessed using Spearman's rho correlation coefficients (ρ). Results: Twenty-eight residents entered residency training between 2011 and 2017. The average rank position of the trainees during this study was 9.7 (range: 1-22). We found no significant correlation between rank order and faculty evaluation during PGY5 (ρ = 0.097, P = .625) or number of publications (ρ = -0.256, P = .189). Additionally, when assessing the association between rank order and annual Otolaryngology Training Examination-scaled scores, no statistically significant relationship was found between the 2 (P > .05). Conclusion: Our results showed that there were no significant correlations between OHNS rank order and various measures of success in residency training, which aligns with existing literature. Further investigation of this relationship should be conducted to ensure the applicability of our findings.

RESUMO

Description According to theatrical superstition, saying "Macbeth" in the theater when you aren't actively performing or rehearsing foreshadows impending doom. In a similar way, in the hospital, its own production of sorts where medical staff is under pressure to perform, it's the "Q" word. We all dread the "Q" word and are vexed with anyone who dares say it. Yet sometimes wandering the hospital during night float, I often feel a profound sense of "Quiet." The word is typically associated with a lack of it, but I find there is a certain peace with being alone with one's thoughts. Residency can be an isolating endeavor, and this particular type of quiet reflection doesn't come around often in a busy hospital. When it does, I think about the other people in this shared space that we work in who may also be feeling the same way, which is bizarrely comforting. However, I probably wouldn't say so out loud, especially under a full moon.

RESUMO

24/7 critical care staffing has become more commonplace, and their impact on resident training must be carefully considered. At our institution, the Critical Care Resource Intensivist (CCRI) model was implemented to provide in-house dedicated faculty responsible solely for the provision of critical care overnight. An anonymous survey was distributed to all general surgery residents to evaluate CCRI's impact on education and autonomy. Descriptive statistics were completed for quantitative data. Qualitative analysis of free text responses was completed to identify consensus themes. Responses from 26 residents demonstrated they associated CCRI with improved resident education, supervision, and patient care, without limiting autonomy. Qualitative analysis yielded 7 themes, reflecting improvements in patient care and safety, progression of care, operations and procedures, improved education, availability, and independence, but noted potential for conflict. Our findings show 24/7 dedicated intensivist staffing can enhance general surgery resident education without limiting autonomy.

RESUMO

OBJECTIVE: Tonsillectomy is essentially a solo surgery with a well-described complication profile. It may serve as a good benchmark to evaluate the resident-as-surgeon. This study examined complications such as post-tonsillectomy bleeding in children undergoing tonsillectomy by attending surgeons (AS) or pediatric otolaryngologist-supervised residents. METHODS: Charts were reviewed of all children aged 12 and under who had tonsillectomy +/- adenoidectomy at a children's hospital between Jan 2019 and Dec 2020. Patient age, gender, BMI, indication for surgery, surgical technique, presence of a resident surgeon, primary bleeding, secondary bleeding, treatment of bleeding, other Emergency Room (ER) visits, and clinic phone calls were recorded. Binary logistic regression was performed. RESULTS: 2051 total children (1092 (53.2 %) males and 956 (46.6 %) females) with a mean age of 6.1 years (95 % CI 6.0-6.2) were included. 1910 (93.0 %) underwent surgery for tonsillar obstruction. 1557 (75.9 %) underwent monopolar cautery tonsillectomy. 661 (32.2 %) had a resident surgeon. 274 (13.4 %) had a related ER visit within 15 days. 18 (0.9 %) had a primary bleed and 155 (7.6 %) had a secondary bleed. Binary logistic regression showed that significant predictors of postoperative ER visits were patient age (OR = 1.101, 95 % CI = 1.050-1.154, p < .001) and resident involvement (OR = 0.585, 95 % CI = 0.429-,797, p < .001). Only age was associated with overall postoperative bleeding incidence (OR = 1.131, 95 % CI = 1.068-1.197, p < .001), as well as secondary bleeding (OR = 1.128, 95 % CI = 1.063-1.197, p < .001). There were no significant predictors of primary bleeding. CONCLUSION: Resident involvement in pediatric tonsillectomy is associated with decreased postoperative ER utilization and does not appear to increase common postoperative complications including bleeding and dehydration.

RESUMO

OBJECTIVE: To explore residents' perceptions of workplace support inhibitors and their relationship to resident wellbeing. We aim to provide evidence-based targets to inform future work operationalizing support in surgical training. DESIGN: This is a 2-part mixed-methods cross-sectional study. Part 1 analyzed qualitative data from focus groups (April 2021-May 2022). Part 2 comprised an online survey (informed by findings in Part 1, May 2022) to assess the association between perceived workplace support (e.g. feeling valued and value congruence) and poor individual global wellbeing (e.g. languishing). SETTING: National multi-center study including 16 ACGME-accredited academic programs. PARTICIPANTS: General surgery residents at all training levels, both clinical and research years. RESULTS: 28 residents participated in the focus groups which revealed three major themes around perceived inhibitors of workplace support: lack of trust in residency program (e.g. ulterior motives), poor communication from leadership (e.g. lack of transparency, ineffective dialogue), and unfair systems in residency training (e.g. exploitation of residents, paternal leave policies). These themes emphasized the importance of feeling valued and value congruence, with the latter reflected in the form of trust and communication with leadership, a key element of worker-workplace alignment. 251 residents responded to the survey (response rate 31%, 50.6% women) which revealed that a lower sense of feeling valued and lower perceived value congruence were significantly associated with languishing. CONCLUSIONS: Our findings suggest feeling valued and value congruence (specifically, having trust and communication with leadership) are important targets for increasing workplace support in surgical training, offering evidence-based targets for future work to operationalize support in surgical training.

RESUMO

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease of the CNS characterized by the production of disease-specific autoantibodies against aquaporin-4 (AQP4) water channels. Animal model studies suggest that anti-AQP4 antibodies cause a loss of AQP4-expressing astrocytes, primarily via complement-dependent cytotoxicity. Nonetheless, several aspects of the disease remain unclear, including: how anti-AQP4 antibodies cross the blood-brain barrier from the periphery to the CNS; how NMOSD expands into longitudinally extensive transverse myelitis or optic neuritis; how multiphasic courses occur; and how to prevent attacks without depleting circulating anti-AQP4 antibodies, especially when employing B-cell-depleting therapies. To address these knowledge gaps, we conducted a comprehensive 'stage-dependent' investigation of immune cell elements in situ in human NMOSD lesions, based on neuropathological techniques for autopsied/biopsied CNS materials. The present study provided three major findings. First, activated or netting neutrophils and melanoma cell adhesion molecule-positive (MCAM+) helper T (TH) 17/cytotoxic T (TC) 17 cells are prominent, and the numbers of these correlate with the size of NMOSD lesions in the initial or early-active stages. Second, forkhead box P3-positive (FOXP3+) regulatory T (Treg) cells are recruited to NMOSD lesions during the initial, early-active or late-active stages, suggesting rapid suppression of proinflammatory autoimmune events in the active stages of NMOSD. Third, compartmentalized resident memory immune cells, including CD103+ tissue-resident memory T (TRM) cells with long-lasting inflammatory potential, are detected under "standby" conditions in all stages. Furthermore, CD103+ TRM cells express high levels of granzyme B/perforin-1 in the initial or early-active stages of NMOSD in situ. We infer that stage-dependent compartmentalized immune traits orchestrate the pathology of anti-AQP4 antibody-guided NMOSD in situ. Our work further suggests that targeting activated/netting neutrophils, MCAM+ TH17/TC17 cells, and CD103+ TRM cells, as well as promoting the expansion of FOXP3+ Treg cells, may be effective in treating and preventing relapses of NMOSD.
