RESUMO
BACKGROUND: Telehealth technologies offer efficient ways to deliver health-related social needs (HRSN) screening in cancer care, but these methods may not reach all populations. The authors examined patient characteristics associated with using an online patient portal (OPP) to complete HRSN screening as part of gynecologic cancer care. METHODS: From June 2021 to June 2023, patients in a gynecologic oncology clinic completed validated HRSN screening questions either (1) using the OPP (independently before the visit) or (2) in person (verbally administered by clinic staff). The authors examined the prevalence of HRSN according to activated OPP status and, in a restricted subgroup, used stepwise multivariate Poisson regression to identify associations between patient and visit characteristics and using the OPP. RESULTS: Of 1616 patients, 87.4% (n = 1413) had an activated OPP. Patients with inactive OPPs (vs. activated OPPs) more frequently reported two or more needs (10% vs 5%; p < .01). Of 986 patients in the restricted cohort, 52% used the OPP to complete screening. The final multivariable model indicated that patients were less likely to use the OPP if they were Black (vs. White; adjusted relative risk [aRR], 0.70; 95% confidence interval [CI], 0.59-0.83); not employed (vs. employed; aRR, 0.81; 95% CI, 0.68-0.97), or had low measures of OPP engagement (aRR, 0.80; 95% CI, 0.68-0.92). New versus established patients were 21% more likely to use the OPP (aRR, 1.21; 95% CI, 1.06-1.38). CONCLUSIONS: Differential use of the OPP suggested that over-reliance on digital technologies could limit the ability to reach those populations that have social factors already associated with cancer outcome disparities. Cancer centers should consider using multiple delivery methods for HRSN screening to maximize reach to all populations.
RESUMO
Lanthanide-doped upconversion (UC) materials have been extensively investigated for their unique capability to convert low-energy excitation into high-energy emission. Contrary to previous reports suggesting that efficient UC luminescence (UCL) is exclusively observed in materials with a wide bandgap, we have discovered in this study that Y2Mo4O15:Yb3+/Tm3+ microcrystals, a narrowband material, exhibit highly efficient UC emission. Remarkably, these microcrystals do not display any four- or five-photon UC emission bands. This particular optical phenomenon is independent of the variation in doping ion concentration, temperature, phonon energy, and excitation power density. Combining theoretical calculations and experimental results, we attribute the vanishing emission bands to the strong interaction between the bandgap of the Y2Mo4O15 host matrix (3.37â eV) and the high-energy levels (1I6 and 1D2) of Tm3+ ions. This interaction can effectively catalyze the UC emission process of Tm3+ ions, which leads to Y2Mo4O15:Yb3+/Tm3+ microcrystals possessing very strong UCL intensity. The brightness of these microcrystals outshines commercial UC NaYF4:Yb3+,Er3+ green phosphors by a factor of 10 and is 1.4 times greater than that of UC NaYF4:Yb3+,Tm3+ blue phosphors. Ultimately, Y2Mo4O15:Yb3+/Tm3+ microcrystals, with their distinctive optical characteristics, are being tailored for sophisticated anti-counterfeiting and information encryption applications.
RESUMO
Upconversion (UC) materials are renowned for their ability to convert low-energy photons into high-energy ones. The manipulation of parameters allows for the observation of multicolored UC luminescence (UCL) within a single material system. While modulation of multicolored UCL commonly relies on excitation at approximately 980â nm, investigation into multicolored UC materials activated by a 1532â nm excitation source remains comparatively scarce. In this work, we introduce NaLnF4:Er3+ as a novel class of smart luminescent materials. When the power density of a 1532â nm laser increases from 0.5 to 20.0â W/cm2, the emission peak positions remain unchanged, but the red-to-green (R/G) ratio decreases significantly from 18.82 to 1.48, inducing a color shift from red to yellow and ultimately to green. In contrast, no color variation is observed when NaLnF4:Er3+ is excited with a 980â nm laser at different power densities. This power-dependent multicolored UCL of NaLnF4:Er3+ excited at 1532â nm can be attributed to the competitive processes of upward pumping and downward relaxation of electrons on the 4I9/2 level of Er3+. By utilizing the unique UC characteristics of NaLnF4:Er3+, its potential utility in anti-counterfeiting applications is demonstrated. Our research highlights the distinctive optical properties of NaLnF4:Er3+ and provides novel insights into the use of luminescent materials in optical anti-counterfeiting technologies.
RESUMO
CONTEXT: Qing Cuo Formula (QCF) is a traditional Chinese medicine for treating acne, but its active compounds and molecular mechanisms are unclear. OBJECTIVE: To investigate the material basis and molecular mechanism of QCF. MATERIALS AND METHODS: In vivo experiments were conducted on 60 male golden hamsters with damp-heat acne, with a blank group, a spironolactone group and 3 QCF administration groups (given high, medium and low doses) over a 30-day period. Serum androgen and inflammatory cytokine levels were tested by ELISA. In vitro, chemical compositions of QCF were investigated by UPLC-LTQ-Orbitrap-MS. Network pharmacology approaches were used to analyse the protein-protein interaction (PPI) network and QCF active compounds-intersection targets-acne network. GO enrichment and KEGG pathway analysis was conducted subsequently. RESULTS: Low-dose QCF group (11.4 g/kg/day) showed significantly reduced levels of serum T (4.94 ± 0.36; 5.51 ± 0.36 ng/mL), DHT (6.67 ± 0.61; 8.09 ± 0.59 nmol/L), E2 (209.01 ± 20.92; 237.08 ± 13.94 pg/mL), IL-1α (36.84 ± 3.23; 44.07 ± 4.00 pg/mL) and FFA (128.32 ± 10.94; 148.00 ± 12.12 µmol/L) compared to the blank group (p < 0.05). In vitro experiments identified 75 compounds in QCF decoction, with 27 active compounds absorbed in serum. Network pharmacology identified 6 active components connecting 17 targets. GO enrichment and KEGG pathway analysis indicated that QCF's anti-acne targets mainly regulate extracellular matrix function, inflammatory processes, immune response and endocrine function. CONCLUSIONS: This study provides evidence of the molecular mechanism and material basis of QCF in treating androgen-related damp-heat acne, paving the way for further research on its potential in treating other conditions related to damp-heat constitution.

OPINION STATEMENT: Total hysterectomy with lymph node assessment is the current standard-of-care for surgical staging in apparent early-stage endometrial cancer. Compared to the traditional complete pelvic lymphadenectomy with or without para-aortic lymphadenectomy, sentinel lymph node (SLN) mapping results in fewer surgical complications, decreased operative time, and lower rates of chronic lymphedema. The technique is endorsed by the National Comprehensive Cancer Network and the Society of Gynecologic Oncology guidelines, and over the past two decades the majority of gynecologic oncologists worldwide have adopted SLN mapping into their practice. However, as the results of the initial SLN studies were mostly based on low-grade tumors, adoption of the technique in high-grade tumors has been slower and more controversial. In this review, we discuss the most recent studies evaluating the SLN mapping in high-grade endometrial cancers. The results of these studies suggest that the SLN detection rate is acceptably high and the negative predictive value is sufficiently low to support the use of SLN mapping in high-grade endometrial tumors to replace complete lymphadenectomy. Validity of SLN mapping techniques does, however, require following a standard algorithm, and success depends also on surgeon expertise. Moreover, the impact of SLN mapping on overall survival in high-grade tumors requires future prospective randomized studies. Finally, a transition toward near-universal SLN mapping techniques for endometrial cancers could significantly impact on the adequacy of gynecologic oncology fellows' surgical training and competency in lymphadenectomy.

Peritoneal metastasis is common in advanced gastric cancer patients and is typically associated with a worse prognosis. ß-Elemene is a natural compound that can be isolated from the Curcuma wenyujin plant and has been widely used in China to treat a variety of cancers. However, the anti-metastatic impacts of ß-elemene on gastric cancer remain unknown. In our study, we found that ß-elemene significantly inhibited the migration and invasive capacity of gastric cells in vitro and inhibited the capacity of gastric cancer cells to peritoneally diffuse and metastasize in vivo. Mechanistically, we demonstrated that the anti-metastatic effects of ß-elemene were exerted by downregulating the expression of Claudin-1. Furthermore, ß-elemene was found to inhibit the metastatic capacity of cells by downregulating FAK phosphorylation, which regulated Claudin-1. Overall, our result revealed that ß-elemene inhibited peritoneal metastases from gastric cancer by modulating the FAK/Claudin-1 pathway.

BACKGROUND/AIMS: The transcription cofactor limb-bud and heart (LBH) is involved in embryonic development. However, its role in human lung cancer, especially lung adenocarcinoma (LUAD), remains unclear. METHODS: A public database and tissue microarray (TMA) were used to compare differences in LBH expression and its relationship with clinical characteristics. Tissue from an additional 70 LUAD patients with follow-up records was used to explore the correlation of LBH expression with prognosis. Cellular and molecular studies validated the role of LBH in LUAD growth and invasion. RESULTS: LBH was significantly down-regulated in lung cancer tissue samples and was correlated with the prognosis and clinical characteristics of lung cancer patients based on a public database and TMA. Survival analysis revealed that LBH-negative expression was associated with poor overall survival of LUAD patients (P = 0.021). Cox regression analysis showed that LBH expression status was a favorable independent prognostic factor (hazard ratio = 0.120, 95% confidence interval = 0.016-0.894, P = 0.039). LBH knockdown accelerated LUAD cell proliferation, migration, and invasion. Furthermore, bioinformatics analysis indicated that LBH was significantly related to the cell adhesion pathway. Western blot analysis confirmed that LBH could regulate the expression of integrin family members (integrin-α1, integrin-α2, integrin-α4, integrin-αv, and integrin-ß4). CONCLUSION: Our data suggest that LBH plays an important role in lung cancer. Importantly, LBH is an independent prognostic factor in LUAD and can attenuate cell growth and invasion. LBH may be a potential prognostic biomarker in LUAD patients.

BACKGROUND: The antioxidant status of the human skin provides protection against the destructive action of free radicals. Most antioxidants cannot be synthesized by the human organism itself, but have to be ingested with a healthy nutrition rich in fruit and vegetables. The Korean cuisine is known to be one of the healthiest worldwide. This binational study investigated the cutaneous carotenoid concentrations in German subjects, South Korean subjects and immigrant Korean subjects resident in Germany and examined whether dietary- and lifestyle-related differences are reflected in the cutaneous carotenoid concentrations. METHODS: Measurements of the carotenoid concentrations of 714 healthy volunteers were performed using a non-invasive spectroscopic measurement system based on reflectance spectroscopy. RESULTS: In the present study South Korean residents showed a significantly higher antioxidant status than both native German residents and Korean immigrants living in Germany (p < 0.001). The first generation of Korean immigrants to Germany over the age of 50 mostly preserved Korean dietary habits, showing significantly higher concentrations (p < 0.001) than the German-born second and third Korean generations under the age of 50. CONCLUSION: The results of the study indicate that a healthy nutrition alone does not provide a high antioxidant status unless the stress exposure can be reduced simultaneously.

BACKGROUND: Traditional Chinese Medicine (TCM) defines constitutions which are relevant to corresponding diseases among people. As one of the common constitutions, Yin-deficiency constitution influences a number of Chinese population in the disease onset. Therefore, accurate Yin-deficiency constitution identification is significant for disease prevention and treatment. METHODS: In this study, we collected participants with Yin-deficiency constitution and balanced constitution, separately. The least absolute shrinkage and selection operator (LASSO) and logistic regression were used to analyze genetic predictors. Four machine learning models for Yin-deficiency constitution classification with multiple combined genetic indicators were integrated to analyze and identify the optimal model and features. The Shapley Additive exPlanations (SHAP) interpretation was developed for model explanation. RESULTS: The results showed that, NFKBIA, BCL2A1 and CCL4 were the most associated genetic indicators with Yin-deficiency constitution. Random forest with three genetic predictors including NFKBIA, BCL2A1 and CCL4 was the optimal model, area under curve (AUC): 0.937 (95% CI 0.844-1.000), sensitivity: 0.870, specificity: 0.900. The SHAP method provided an intuitive explanation of risk leading to individual predictions. CONCLUSION: We constructed a Yin-deficiency constitution classification model based on machine learning and explained it with the SHAP method, providing an objective Yin-deficiency constitution identification system in TCM and the guidance for clinicians.
RESUMO
Background: A combination of standard biomedical treatment and traditional Chinese medicine (TCM) has been suggested as a therapeutic approach for rosacea that may significantly lower the recurrence rate and clinical symptom scores. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the impact of this combination treatment on clinical symptom and TCM syndrome scores, as well as on the scores of the Dermatology Life Quality Index (DLQI), erythema index (EI), and interleukin 37 (IL-37) levels in patients with rosacea. Methods: The PROSPERO registration number for the study is CRD42023472737. We systematically searched the PubMed, Embase, Web of Science, China National Knowledge Infrastructure Wanfang Database, China Biomedical Medicine database (CBM), and the VIP information resource integration service platform (cqvip) databases for RCTs (published from the beginning to September 2023, regardless of the language used) that compared the traditional Chinese medicine and standard biomedical treatment combination treatment to conventional anti-rosacea treatments. Our primary outcomes comprised the clinical symptom and TCM syndrome scores, and the scores of Dermatology Life Quality Index, erythema index, and IL-37 levels. We used a random-effects model to evaluate the pooled data. Results: We identified 260 studies. Of these, 13 eligible studies were employed for analysis (N = 1,348 participants). Compared with other anti-rosacea treatments, the TCM and standard biomedical treatment combination treatment yielded an improved mean reduction in the clinical symptom score -2.24% [95% CI (-3.02 to -1.46), p < 0.00001], TCM syndrome score -4.42 [95% CI (-5.33 to -3.50), p < 0.00001], and the score of DLQI of -2.55 [95% CI (-3.73 to -1.36), p < 0.00001], EI of -151.97 [95% CI (-276.59 to -27.36), p < 0.00001], and IL-37 level -4.23 [95% CI (-4.95 to -3.51), p = 0.854], as well as in the overall effective rate risk ratio (RR) = 1.25 [95%CI (1.18, 1.32), p = 0.994] and the recurrence rate = 0.27 [95%CI (0.15, 0.46), p = 0.297]. Conclusion: The TCM and standard biomedical treatment combination treatment can provide a better outcome, including a reduction in the TCM syndrome and clinical symptom scores, and in the scores of DLQI, EI, and IL-37. Hence, this combination is a viable and more effective therapeutic approach for rosacea. However, these results should be considered cautiously because of uncertain evidence and the low quality of the study reports considered in this meta-analysis.

RESUMO
PURPOSE: We previously implemented paper-based screening for health-related social resource needs (HRSN) in our gynecologic oncology clinic and found that 36% of patients who completed the screening reported HRSN. We identified two primary deficiencies with our process. First, only 52% of patients completed the screening. Second, 37% of patients with needs failed to indicate if they desired resource referral or not. Therefore, we conducted a quality improvement project to integrate screening and referral processes into the electronic medical record (EMR) and routine clinic workflow to achieve at least 90% screening compliance and 90% elicited referral preference. METHODS: A multidisciplinary team consisting of physicians, a health outcomes researcher, a computer programmer, project assistants, and the staff of a partner community organization designed and implemented an intervention that screened for HRSN online via the EMR patient platform or in person during visits. The primary outcome was the percentage of eligible patients who completed the HRSN screening (ie, reach). Outcomes were reviewed weekly, and feedback was provided to stakeholders monthly. Iterative changes were incorporated into five successive Plan-Do-Study-Act (PDSA) cycles completed from January 2021 to March 2023. RESULTS: Screening compliance increased from the baseline of 52% (paper-based) to 97% in PDSA 4. Completion via the online patient portal increased from 17% in prelaunch to 49% in PDSA 4. Of patients who reported needs, 100% had a documented referral preference. CONCLUSION: Compared with paper-based screening, an EMR-integrated HRSN screening and referral system significantly improved reach to patients at a gynecologic oncology clinic. Implementation efforts to expand to other ambulatory clinic settings are in process.

STUDY OBJECTIVE: Youth account for half of new sexually transmitted infections (STIs) in the United States annually. Barriers to STI prevention include a lack of accurate sexual and reproductive health (SRH) education and low STI testing. We sought to obtain youth feedback on a digital health platform prototype designed to address these barriers. METHODS: The platform prototype included SRH content, free STI testing and treatment, and anonymous question submission. Five focus group discussions, each lasting 45-60 minutes with 5-6 youth living in a high-prevalence STI region (Baltimore, Maryland), were conducted. Thematic analysis was conducted. RESULTS: There were 28 participants with a mean age of 15.9 years (range 14-19), among whom 89% self-identified as female, 57% Black/African American, 29% Asian American, 14% White, and 7% Hispanic/Latino. Youth felt that the prototype platform was comprehensive and understandable. They suggested adding peer reviews to increase trustworthiness. CONCLUSION: Youth reported that the platform (violetproject.org) was an acceptable tool for SRH education and STI testing. Participants expressed enthusiasm and willingness to use the platform as a reliable SRH educational tool to combat medical misinformation on the Internet and a non-clinic-based source of STI testing. This platform could fill gaps in access to SRH care and education for youth.

PURPOSE: Youth face barriers to sexual and reproductive health (SRH). Few states require the delivery of comprehensive sex education in schools, and youth report challenges with accessing clinical care. We sought to identify youth's perceived barriers and facilitators to SRH in their communities. METHODS: We utilized photovoice, a community-based participatory research methodology. Youth were recruited from high schools in Baltimore, Maryland. Participants were given a tutorial on Photovoice methodology and photography. In groups of 5-7 participants, youth brainstormed questions relevant to their perspective of SRH. Three months were allocated to taking photographs. Participants wrote brief narratives to accompany their photographs, and group level assessment was used for participants to comment on others' photographs. Participants discussed the narratives and comments, created themes, and generated action steps to address barriers to SRH. Further thematic analysis was conducted using NVivo. RESULTS: There were 30 participants aged 14-19 years with 26 self-identifying as female and four nonbinary. Self-identified race/ethnicity included 50% Black/African American, 30% Asian American, and 20% White or Hispanic/Latino. Four domains emerged: desire for societal-level change, community-level change, peer-level change, and positive examples of SRH within their communities (e.g., gender-inclusive spaces and free menstrual products). DISCUSSION: Youth photographs shed light on a strong desire for an improved school environment, in terms of safety, cleanliness, gender-inclusivity, menstrual product access, and SRH education.

PURPOSE: The COVID-19 pandemic highlighted the need for innovative approaches to delivering care. Self-collect, mail-in sexually transmitted infection (STI) testing could address barriers to in-person STI testing, particularly for youth, who bear a disproportionate burden of STIs. This study sought to obtain youth input on the development of a free self-collect, mail-in STI testing program. METHODS: Focus group discussions (n = 5, 45-60 minutes each) were conducted with 28 youth ages 14-19 years old living in Baltimore, Maryland. Focus group discussions were based on a conceptual framework of patient-centered health-care access, and a prototype online program was discussed. Transcribed data were coded thematically. Memos were written to synthesize findings and identify representative quotes. RESULTS: Participants noted existing barriers to in-person STI testing barriers including individual-level (e.g., lack of knowledge), interpersonal-level (e.g., stigma), and structural-level (e.g., financial). Although participants expressed concerns about self-collect, mail-in STI testing (e.g., accuracy of self-swabbing), there was overall acceptance of the program, and many felt it would address current barriers to testing. Opportunities to improve the testing program included all four steps of testing process: kit ordering, receipt of the kit and swabbing, post-testing experience, and communication of results and treatment. Specifically, participants desired expanded shipping options to schools, and mail drop-off points such as lockers and local convenience stores; more transparency about testing and treatment; and hearing directly from health-care providers to assuage any concerns. DISCUSSION: Self-collect, mail-in STI testing was favorable among youth, and could be a viable option for increasing youth access to STI testing.

Asian American women are turning to oocyte cryopreservation (egg freezing) at rates higher than would be expected, given that Asian Americans make up less than six percent of the total United States population. Based on ethnographic interviews with 23 women of East, Southeast, and South Asian ancestry, we examine the "fertility paradox" faced by highly educated Asian American professional women. Despite achieving multiple "pillars of success," these women have difficulty finding educated partners with whom to pursue childbearing. Egg freezing offers feelings of empowerment and relief from pressure for Asian American women, holding open the possibility of future biogenetic motherhood.

BACKGROUND: Traditional Chinese Medicine (TCM) defined constitution as a health statue or physical fitness that determines individual susceptibility to diseases. Yin deficiency constitution (YinDC) is a type of constitution closely related to aging. Previous studies found that the characteristic genes of YinDC are part of the inflammatory aging signaling pathways (e.g., NF-kappa B). Therefore, the aim of the study was to further reveal the dysregulation of genes associated with inflammatory aging in YinDC women. METHODS: This study adopted the industrial standard of constitutional judgment, and screened YinDC (n = 30) and Balanced constitution (BC) (n = 30) from women between the ages of 35 to 49, a range categorized as the degenerating period by TCM. Five genes CCL4, BCL2A1, NFKBIA, TAK1, and IL-8 were analyzed by qRT-PCR. RESULTS: Logistical regression revealed the correlation between body constitution and the expression of the five genes: the expression of NFKBIA and CCL4 mRNA was significantly up-regulated, whereas the expression of BCL2A1 mRNA was significantly down-regulated in YinDC (P < 0.05). Age or weight, when included in the model, did not affected the correlations. CONCLUSION: Increased mRNA expression of CCL4 and NFKBIA and decreased mRNA expression of BCL2A1 may be the molecular basis of premature aging of YinDC women. These results provide a mechanistic basis for early conditioning of YinDC, anti-aging, and the prevention of aging-related diseases.

Background: Gastric cancer (GC) still represents the third leading cause of cancer-related death worldwide. Peritoneal relapse (PR) is the most frequent metastasis occurring among patients with advanced gastric cancer. Increasingly more evidence have clarified the tumor immune microenvironment (TIME) may predict survival and have clinical significance in GC. However, tumor-transcriptomics based immune signatures derived from immune profiling have not been established for predicting the peritoneal recurrence of the advanced GC. Methods: In this study, we depict the immune landscape of GC by using transcriptome profiling and clinical characteristics retrieved from GSE62254 of Gene Expression Omnibus (GEO). Immune cell infiltration score was evaluated via single-sample gene set enrichment (ssGSEA) analysis algorithm. The least absolute shrinkage and selection operator (LASSO) Cox regression algorithm was used to select the valuable immune cells and construct the final model for the prediction of PR. The receiver operating characteristic (ROC) curve and the Kaplan-Meier curve were used to check the accuracy of PRIs. Gene Set Enrichment Analysis (GSEA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed to explore the molecular pathways associated with PRIs. Results: A peritoneal recurrence related immune score (PRIs) with 10 immune cells was constructed. Compared to the low-PRIs group, the high-PRIs group had a greater risk. The upregulation of the focal adhesion signaling was observed in the high-PRIs subtype by GSEA and KEGG. Multivariate analysis found that both in the internal training cohort and the internal validation cohort, PRIs was a stable and independent predictor for PR. A nomogram that integrated clinicopathological features and PRIs to predict peritoneal relapse was constructed. Subgroup analysis indicated that the PRIs could obviously distinguish peritoneal recurrence in different molecular subtypes, pathological stages and Lauren subtypes, in which PRIs of Epithelial-Mesenchymal Transitions (EMT) subtype, III-IV stage and diffuse subtype are higher respectively. Conclusion: Overall, we performed a comprehensive evaluation of the immune landscape of GC and constructed a predictive PR model based on the immune cell infiltration. The PRIs represents novel promising feature of predicting peritoneal recurrence of GC and sheds light on the improvement of the personalized management of GC patients after surgery.

Aim: This research aimed to elucidate the prognosis values of prognostic nutritional index (PNI) and systemic immune-inflammation index (SII) and clinical characteristics in NSCLC patients with brain metastases (BM) underwent radiotherapy. Materials & methods: Cut-off points of hematological indicators were determined by receiver operating characteristic curve. Overall survival was evaluated by Kaplan-Meier method and Cox proportional hazards model. Results: We retrospectively analyzed 214 patients from January 2009 to December 2018. The result demonstrated the independent prognostic values of PNI (hazard ratio: 0.600; p = 0.004) and SII (hazard ratio: 1.486; p = 0.019). The remaining clinicopathologic factors, including brain radiotherapy modality, smoking history, numbers of brain metastases, intracranial symptoms and Radiation Therapy Oncology Group - recursive partitioning analysis, were independently related to survival (p < 0.05). Conclusion: PNI and SII could be critical prognostic indicators for NSCLC patients with BM.

In recent years, immune checkpoint inhibitors (ICIs) have become a standard treatment for patients with advanced lung cancers. With the widespread use of immunotherapy in clinical practice, immune-related adverse events (irAEs) have become increasingly common. This case report details a 72-year-old man with small-cell lung cancer (SCLC) who developed pneumonitis, appendicitis, and biliary obstruction during treatment with toripalimab. The patient was initially diagnosed with limited-stage SCLC in January 2019 and completed 5 sequential cycles of etoposide/cisplatin (EP) and radiotherapy (60 Gy/30 F). The overall response was complete response (CR) after first line treatment. He developed radiation pneumonitis after completion of radiotherapy, which responded well to symptomatic treatment. Due to newly diagnosed bone metastasis, he was administered toripalimab intravenously every 3 weeks and 12 mg anlotinib orally once a day from January 2020. By the third cycle, the patient presented with electrocardiographic abnormalities, gingival swelling and pain, and hoarseness, and consequently, the anlotinib was suspended. After 4 cycles, he developed suppurative appendicitis, which was managed successfully with anti-inflammatory agents. He then presented with shortness of breath on exertion and after a comprehensive examination, he was diagnosed with ICI-related-pneumonitis. After 6 weeks of treatment with methylprednisolone, the shortness of breath was mostly relieved and treatment continued. In June 2020, the patient developed severe vomiting. Computed tomography (CT) indicated biliary obstruction, and at endoscopic retrograde cholangiopancreatography (ERCP) there was edema of the major papilla of the duodenum. The patient's symptoms were relieved after treatment with gastric acid suppression and antiemetics. Re-examination by magnetic resonance imaging (MRI) showed that the biliary obstruction had been resolved. Although the disease progressed after immunotherapy, no tumor tissue related to the biliary obstruction was detected, and this was therefore classified as an irAE.

Estimating hospital mortality of patients is important in assisting clinicians to make decisions and hospital providers to allocate resources. This paper proposed a multi-task recurrent neural network with attention mechanisms to predict patients' hospital mortality, using reconstruction of patients' physiological time series as an auxiliary task. Experiments were conducted on a large public electronic health record database, i.e., MIMIC-III. Fifteen physiological measurements during the first 24 h of critical care were used to predict death before hospital discharge. Compared with the conventional simplified acute physiology score (SAPS-II), the proposed multi-task learning model achieved better sensitivity (0.503 ± 0.020 versus 0.365 ± 0.021), when predictions were made based on the same 24-h observation period. The multi-task learning model is recommended to be updated daily with at least a 6-h observation period, in order for it to perform similarly or better than the SAPS-II. In the future, the need for intervention can be considered as another task to further optimize the performance of the multi-task learning model.
