OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events （irCAEs） caused by durvalumab， and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history， and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile， the clinical pharmacists conducted a graded assessment of the adverse reaction， proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids， assisted physicians in restarting immunotherapy， and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion， and after symptomatic treatment， the patient’s skin symptoms improved， and discharged with medication. After the completion of glucocorticoid therapy for the patient， the physician restarted immunotherapy with tislelizumab， and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice， it is crucial to promptly identify and discontinue suspicious drugs， immediately implement effective symptomatic treatment measures， and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

Objective To evaluate the image quality of abdominal dual-energy CT virtual monoenergetic imaging (VMI) in patients with early gastric cancer using titanium alloy clips and assess its effectiveness on reducing metal artifacts. Methods A retrospective study was conducted, including 31 patients with gastric cancer who underwent abdominal dual-energy CT scans with titanium clips inserted in the gastric cavity. Each scan was reconstructed into mixed images (simulated 120 kVp CT) and VMIs with energy levels ranging from 40 keV to 140 keV. Metal artifacts were quantitatively evaluated by measuring the noise values in the lesion and perigastric regions. The contrast-noise ratio (CNR) of the lesion and the corresponding liver tissue was calculated to assess the image quality. Two radiologists independently evaluated the images, considering overall quality, artifact severity, lesion conspicuity, perigastric clarity, and vascular contrast. Results Quantitative analysis revealed that metal artifacts in both the lesion and perigastric regions decreased as the energy level increased. VMIs at 80-140 keV (lesion site) and 90-140 keV (perigastric space) showed significantly fewer artifacts compared to mixed images (P＜0.05). The CNR of lesions remained stable across VMIs at 50-140 keV, while the CNR of normal liver tissue decreased significantly with increasing energy (P＜0.05). In the subjective assessment, VMIs at 80-140 keV had higher artifact scores than mixed images (P＜0.05). VMIs at 70-90 keV provided better lesion conspicuity and perigastric clarity, although vascular contrast decreased significantly with increasing energy (P＜0.05). VMIs at 70-90 keV showed better overall quality (P＜0.05), though not significantly different from mixed images. Conclusions VMIs at 80 keV and 90 keV improve the visibility of lesions and perigastric regions affected by metallic clips, which combined with mixed images can enhance radiologists’ diagnostic accuracy.

OBJECTIVE To analyze the correlation of the peak blood concentration （cmax） of compound sulfamethoxazole （TMP/SMZ） and its metabolite N-acetyl sulfamethoxazole （NSMZ） with clinical efficacy and adverse reactions in critically ill patients. METHODS The data of critically ill patients treated with TMP/SMZ in various ICU of Hainan General Hospital from December 2023 to January 2025 were retrospectively collected. The patients were divided into success group and failure group based on the treatment outcome. Simple linear regression and Spearman correlation analysis were used to analyze the correlation of TMP cmax， SMZ cmax， and NSMZ cmax with clinical efficacy and adverse reactions. The receiver operating characteristic curve （ROC） was used to determine the cutoff values of cmax for predicting the occurrence of adverse reactions. RESULTS Among critically ill patients with an acute physiology and chronic health evaluation Ⅱ （APACHE-Ⅱ） ≥15 points 24 h of check-in at ICU， SMZ cmax of success group was significantly higher than failure group （P＜0.05）. The daily total dose of TMP/SMZ was positively correlated with TMP cmax and SMZ cmax（ P＜0.05）. TMP cmax was significantly correlated with hepatotoxicity and nephrotoxicity， SMZ cmax with hepatotoxicity， and NSMZ cmax with nephrotoxicity （P＜0.05）. The cutoff values of TMP cmax for predicting nephrotoxicity and hepatotoxicity were 7.25 μg/mL and 6.63 μg/mL， respectively. The cutoff value of SMZ cmax for predicting hepatotoxicity was 138.00 μg/mL， and that of NSMZ cmax for predicting nephrotoxicity was 60.76 μg/mL. CONCLUSIONS Among critically ill patients with an APACHE-Ⅱ ≥15 points 24 h of check-in at ICU， SMZ cmax is associated with treatment success. Hepatotoxicity risk significantly increases when TMP cmax ≥6.63 μg/mL or SMZ cmax ≥138.00 μg/mL； nephrotoxicity risk significantly increases when TMP cmax ≥7.25 μg/mL or NSMZ cmax ≥60.76 μg/mL.

Objective To investigate the correlation of SII with occurrence of short-term MI in eld-erly patients with CHD complicated with T2DM.Methods A total of 382 CHD patients with con-comitant T2DM admitted in our hospital from January 2022 to January 2023 were enrolled,and according to occurrence of MI within 1 year,they were divided into a MI group(83 patients)and a non-MI group(299 patients).Clinical data were collected,and multivariate logistic regression analysis was used to determine the risk factors for MI in the patients.ROC curve was plotted to evaluate the predictive value of SII,fasting blood glucose(FPG)and their combination for 1-year MI occurrence.Kaplan-Meier curve was drawn to analyze the relationship between SII and MI.Results Multivariate logistic regression analysis showed that SII,FPG and peripheral atheroscle-rosis were risk factors for MI occurrence(OR=1.001,95％CI:1.000-1.001,P=0.001;OR=1.106,95％CI:1.016-1.203,P=0.020;OR=4.798,95％CI:2.621-8.786,P=0.000),and GLP-1RA and SGLT2i were protective factors for the occurrence(OR=0.255,95％CI:0.073-0.895,P=0.033;OR=0.474,95％CI:0.270-0.834,P=0.010).ROC curve analysis indicated showed that the AUC value of SII,FPG and their combination was 0.675,0.619 and 0.702,respectively,and the predictive performance was better in the combination than the indicator alone(P＜0.01).Kaplan-Meier curve analysis revealed that the cumulative survival rate in the high-level group was significantly lower than that in the low-level group(Plog rank＜0.01).Conclusion For the elderly T2DM patients with concomitant CHD,SII,FPG and atherosclerosis are independ-ent risk factors for MI occurrence.SII and FPG have certain predictive value for the occurrence.

Objective:To investigate the clinical manifestations, pathological features, treatment methods and prognosis of primary renal synovial sarcoma (PRSS) in order to improve the clinical understanding and treatment level of the disease.Methods:The clinical data, pathological features, immunohistochemical indexes, SYT gene detection, treatment and follow-up results of 21 patients with PRSS reported in the First Affiliated Hospital of Soochow University from 2018 to 2023 were retrospectively analyzed. Kaplan-Meier method was used to calculate the relationship between age and cumulative survival rate. Results:The male to female ratio of PRSS patients was 16∶5, the ratio of left and right kidneys was 7∶14, the median age was 50 years old, the mean age was 44.5 years old, the median tumor length diameter was 9.7 cm, and the mean tumor length diameter was 6.7 cm. 57%(12/21) reported low back pain and 48%(10/21) reported gross hematuria. Immunohistochemical examination showed 100% positive for Vimentin(16/16), BCL-2(18/18) and TLE-1(10/10), 69%(9/13) and 85%(6/7) positive for CD99 and CD56, respectively. Genetic testing found SYT translocation signal in 92% of cases (12/13). Next generation sequencing (NGS) detected SS18- SSX1 fusion in 2 cases and SS18- SSX2 fusion in 1 case. SS18- SSX1+ S18- SSX2 fusion was found in 1 case, and one case of SS18- NEDD4 fusion occurred. Preoperative neoadjuvant chemotherapy was performed in 2 cases, postoperative chemotherapy in 11 cases, postoperative chemoradiotherapy in 2 cases, and surgery only in 5 cases. All patients were followed up for 3 to 42 months, and 4 cases were lost to follow-up. Patients with younger onset had a longer cumulative survival time. Patients had a median survival time of 13 months and a mean survival time of 15.4 months. Conclusions:PRSS is more common in middle-aged men, the right kidney is easy to occur, the length of the mass is usually >7 cm, most cases can be initially diagnosed by pathologic morphology, immunophenotype, fluorescence in situ hybridization or NGS STY gene detection can provide accurate diagnosis. The prognosis of PRSS is very poor, and the cumulative survival rate is negatively correlated with the age of onset. Surgical resection combined with chemotherapy is the main treatment for PRSS.

Objective To evaluate the impact of integrated medical and nursing care teaching ward rounds on the theo-retical knowledge learning and clinical operational skill training of primary-level medical staff.Methods A total of 90 clinical healthcare workers(39 physicians and 51 nurses)from our hospital between May and December2024 were randomly assigned to either a control group or an intervention group.The control group participated in traditional three-tier nursing teaching ward rounds,while the intervention group underwent integrated medical and nursing care teaching ward rounds.The two groups were compared in terms of improvements in theoretical knowledge,ward round operational skills,and core clinical competencies.Re-sults Both groups demonstrated improvements in theoretical knowledge and ward round operational skills after the intervention,with the intervention group showing significantly greater gains(P＜0.05).Additionally,scores related to physical fitness,emo-tional well-being,and cognitive function improved in both groups,with significantly higher improvements in the intervention group(P＜0.05).The Clinical Nursing Skills(CINS)scores—including judgment,early warning,anticipatory thinking,and overall clinical competence—also improved significantly in the intervention group compared to the control group(P＜0.05).Conclu-sion Integrated medical and nursing care teaching ward rounds significantly enhance theoretical knowledge,operational profi-ciency,and core clinical competencies among primary healthcare providers.This model fosters higher professional engagement and helps cultivate qualified primary-level medical personnel who are better equipped to meet real-world clinical demands.

Objective:To explore the dilemmas in the discharge preparation process of postoperative breast cancer patients within the framework of Meleis' Transition Theory, and to provide evidence for the development of nursing interventions to improve discharge readiness.Methods:This was a qualitative study. Using purposive sampling, postoperative breast cancer patients hospitalized in the Department of Breast Surgery of Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University between September and October 2024 were selected for the study. Semi-structured, in-depth interviews were conducted. Data were analyzed and themes extracted using Colaizzi's seven-step analysis method.Results:A total of four themes were extracted: personal status-patients experienced complex emotions at discharge; disease knowledge preparation-patients had insufficient mastery of relevant knowledge after discharge; coping ability-patients lacked confidence in home self-care after returning home; social support-patients desired support from peers and medical staff.Conclusions:Postoperative breast cancer patients face multiple dilemmas during discharge preparation. Medical staff are advised to pay attention to the psychological status of discharged patients and develop individualized emotional coping strategies; provide professional information and meet patients' fertility and sexual health knowledge needs; optimize health education models to enhance patients' home coping ability; and strengthen the integration of mobile health with nursing practice to build a multidimensional support system.

Objective:To analyze the application effect of small private online course (SPOC)-based maker education in oncology surgical nursing teaching.Methods:This study enrolled 105 nursing students who completed their internship in the Department of Oncology Surgery from January 2022 to September 2023. The subjects were divided into control group ( n=52, conventional teaching) and observation group ( n=53, SPOC-based maker education) according to their admission order. Before and after teaching, students were evaluated on the theoretical knowledge, operational skills, nursing practice ability, innovation ability, self-learning ability, professional identity, and teamwork ability. The Medical Education Satisfaction Scale (MESS-21) was used to evaluate teaching outcomes. Data were analyzed using the t-test and chi-square test with SPSS 25.0. Results:After teaching, the observation group had higher scores than the control group in theoretical knowledge [(93.60±12.53) vs. (85.90±10.49)], operational skills [(92.63±12.40) vs. (83.75±10.27)], nursing practice ability [(93.50±12.81) vs. (84.72±11.43)], and innovation ability [(91.68±12.53) vs. (80.20±8.37)]; this was also true for learning motivation [(16.63±4.76) vs. (12.90±3.85)], planning and implementation [(16.83±4.77) vs. (13.54±4.32)], self-management [(15.49±4.60) vs. (13.42±4.13)], interpersonal communication [(14.74±4.53) vs. (11.77±3.59)], POIS-M score [(84.61±8.84) vs. (63.53±6.48)], and T-TAQ score [(53.90±5.07) vs. (46.75±4.02)] (all P<0.05). The observation group also had significantly higher scores than the control group in clarity of teaching objectives [(13.58±3.47) vs. (9.14±2.66)], practicality of teaching content [(13.50±3.69) vs. (10.62±2.81)], and supportiveness of teaching resources [(13.92±3.58) vs. (8.88±2.34)]. Conclusions:SPOC-based maker education offers significant advantages in oncology surgical nursing teaching. It effectively enhances nursing students' theoretical knowledge, operational skills, nursing practice ability, innovation ability, self-learning ability, professional identity, and teamwork ability and it is highly valued by students. Its novelty and effectiveness provide new ideas for oncology surgical nursing teaching.
