Association of Immune-Related Adverse Events and the Efficacy of Anti–PD-(L)1 Monotherapy in Non–Small Cell Lung Cancer: Adjusting for Immortal-Time Bias / Journal of the Korean Cancer Association, 대한암학회지

Purpose@# The association between immune-related adverse events (irAEs) and survival outcomes in non–small cell lung cancer (NSCLC) patients treated with programmed death-(ligand) 1 [PD-(L)1] inhibitors remains controversial, partly due to variations in dealing with immortal-time bias (ITB). @*Materials and Methods@# We retrospectively enrolled 425 advanced NSCLC patients who received anti–PD-(L)1 monotherapy between January 2016 and June 2021, stratifying them into irAE (n=127) and non-irAE (n=298) groups. The primary endpoint was to assess the impact of irAEs on progression-free survival (PFS) and overall survival (OS). Landmark (2-, 3-, 6-, and 9-month) and time-dependent Cox analyses were performed to eliminate ITB. @*Results@# With a median follow-up of 38.8 months, the occurrence of overall irAEs was significantly associated with superior PFS (11.2 vs. 3.4 months, p < 0.001) and OS (31.4 vs. 14.0 months, p < 0.001), which persisted in landmark and time-dependent Cox analyses. For the main organ-specific irAEs, skin, thyroid, and hepatic irAEs, respectively, showed significantly improved survival compared to the non-irAE group, whereas pneumonitis did not. Single-organ irAEs had the best outcomes compared with multi-organ or no irAE, which also held across subgroups of skin, thyroid, and hepatic irAEs. Moreover, severe grade irAEs and immunotherapy discontinuation had a detrimental effect on survival, systemic steroid therapy showed little effect, while immunotherapy resumption had tolerable safety and a trend of improved survival. @*Conclusion@# After adequately adjusting ITB, the occurrence of overall irAEs predicts for favorable efficacy of anti–PD-(L)1 monotherapy in NSCLC, with better outcomes observed in patients with skin, thyroid, or hepatic irAEs, particularly those with single-organ involvement.

Applications of collagen extrafibrillar demineralization in dentin bonding / 中华口腔医学杂志

The existing dentin bonding systems based on acid-etching technique lead to the loss of both extrafibrillar and intrafibrillar minerals from dentin collagen, causing excessive demineralization. Because resin monomers can not infiltrate the intrafibrillar spaces of demineralized collagen matrix, degradation of exposed collagen and resin hydrolysis subsequently occur within the hybrid layer, which seriously jeopardizing the longevity of resin-dentin bonding. Collagen extrafibrillar demineralization can effectively avoid the structural defects within the resin-dentin interface caused by acid-etching technique and improve the durability of resin-dentin bonding, by preserving intrafibrillar minerals and selectively demineralizing extrafibrillar dentin. The mechanism and research progress of collagen extrafibrillar demineralization in dentin bonding are reviewed in the paper.

Research progress of histone lactylation in immunomodulation after traumatic brain injury / 中华创伤杂志

Traumatic brain injury (TBI) is a major reason for temporary or permanent dyskinesia and cognitive impairment of the organism. Generally, TBI induces subsequent neuroinflammation to assist cell debris removal and tissue repair and regeneration after injury. However, overactivation or long-term activation of immune cells will exacerbate nerve damage or death, cause cognitive dysfunction, and ultimately lead to neurodegenerative diseases. Therefore, secondary damage caused by persistent inflammation is a key component of TBI pathological process. As the main metabolite of anaerobic glycolysis, lactate is increased after TBI and participates in brain inflammation as an important immune regulatory molecule rather than a metabolic waste. Importantly, histone lysine lactylation as a novel type of histone post-translational modifications (HPTM) derived from lactate allows lactate to participate in the regulation of complex immunopathophysiological processes of the central nervous system after TBI. Further study on the process of histone lactylation and its immune regulation mechanism during TBI may provide new insights for early intervention and improvement of TBI prognosis. Thus, the authors reviewed the role of histone lactylation in the immune regulation of TBI, so as to further elucidate the mechanism of TBI and the explore new warning and prevention measures from the perspective of HPTM.

Status quo and influencing factors of work stress among hospice care physicians and nurses / 中华全科医师杂志

Objective:To investigate the work stress and its influencing factors among hospice care physicians and nurses in medical institutions in Shanghai.Methods:It was a cross-sectional study. The study was carried out between December 2021 and January 2022. By use of multistage random sampling, 256 hospice care physicians and nurses were selected from community healthcare centers, secondary and tertiary hospitals in Shanghai to attend a WeChat-based survey using a self-designed questionnaire. The chi-square test was used to compare the differences in prevalence of work stress and stressors among all subjects with different characteristics. Binary logistic regression analysis was used to explore the major determinants associated with work stress. And the sources of work stress and the expepectd decompression countermeasures were investigated.Results:A total of 256 valid questionnaires were collected with a recovery rate of 100.0%. The median of work stress score was 7.5 (6.0, 9.0). Logistic regression analysis showed that those aged>40 years old and working for ≥5 years in hospice care service had higher level of work stress ( OR=3.78, 2.04; P=0.007, 0.039), and those with monthly income>10 000 RMB Yuan had lower level of work stress ( OR=0.34, P=0.005). The top three stressors were the death of patients (88.3%, 226/256), low income (78.1%, 200/256), difficulty in promotion (67.2%, 172/256). The top three way that doctors and nurses desired to reduce work stress were to increase income (88.3%, 226/256) and optimize performance appraisal target (78.1%, 200/256) and promotion mechanism (66.0%, 169/256). Conclusions:In general, the work stress among hospice care physicians and nurses is at a high level in Shanghai and the stressors are widely distributed. Age, monthly salary and years of working in hospice care unit are independent factors of work stress. Improving salary, optimizing performance appraisal target and promotion mechanism are the most desired strategies to reduce work stress among hospice care physicians and nurses.

The purpose of this review is to summarize the current situation of the management of BTcP at home and abroad, and to discuss the factors that hinder the management of BTcP.

Status quo of hospice care service in community health service centers in Shanghai / 中华全科医师杂志

Objective:To survey the status quo of hospice care service in community health service centers in Shanghai.Methods:A questionnaire survey was conducted to investigate the situation of hospice care services from January 2021 to December 2021 in 16 community health service centers selected by stratified sampling from 16 districts in Shanghai.Results:Among 16 community health service centers, 13 provided inpatient hospice care services, 16 provide home hospice care and 14 provided outpatient hospice care services; and totally 1 935 (77.93%), 158 (6.36%) and 390 (15.71%) patients received palliative care, respectively. In centers providing inpatient hospice care service, the average bed number was 12 (10, 20); the annual number of patients was 58 (29, 137); the average length of hospital stay was (29.55±11.18) days; and the bed occupancy rate was (55.51±30.02)%, which in urban districts was significantly higher than that in rural districts ((74.76±19.33)% vs.(39.00±28.32)%; t=2.61, P=0.024). The number of patients receiving home hospice care in each center was 10 (3, 19) and the average duration of home service was (66.97±29.41) days. The proportion of physician fee of inpatient hospice care and that of home hospice care were (8.61±5.27)% and (6.25±3.11)%, respectively. While the proportion of medication expenses of inpatient hospice care and that of home hospice care were (35.60±16.13)% and(49.58±9.16)%, respectively. The outpatient hospice service were opened 2.0 (1.0, 4.0) days a week in 14 centers and 95 (58, 199) patients received services. Inpatient services were mainly provided for the patients with non-malignant chronic diseases (53.23%, 1 030/1 935), while home hospice care (89.87%, 142/158) and outpatient hospice care (83.85%, 327/390) mainly provided service for malignant patients. Conclusion:There is still room for improvement about the hospice care services delivered by community health service centers in Shanghai:discrepancy of utilization of hospice care services between urban districts and rural districts, low utilization of home and outpatient hospice care services, unreasonable cost composition in inpatient and home hospice care services.
