Real-world treatment patterns and outcomes for patients with CLL using the Australian pharmaceutical benefits scheme (PBS) dataset.

This real-world retrospective cohort study using Australian Pharmaceutical Benefits Scheme (PBS) 10% investigated changes in chronic lymphocytic leukemia (CLL) treatment by line of therapy, time-to-next-treatment, treatment duration, and overall survival (OS). Overall, 803 patients received their first PBS-reimbursed CLL medication between 1 January 2011 to 31 July 2021 (median age: 70 years; 64.6% male), 289 post-1 August 2020. In 2011, most first-line (1 L) prescribing was fludarabine, cyclophosphamide, and rituximab (FCR). By 2021, common 1L were chlorambucil ± CD20 (26.1%), Bruton Tyrosine Kinase inhibitor (BTKi) (26.1%), and CD20 monotherapy (23.9%). In 2011, relapsed/refractory (R/R) CLL treatment was CD20 monotherapy or FCR. By 2021, BTKi (57.7%) and venetoclax ± CD20 (26.1%) were most common. Compared to FCR, 1 L treatment duration (Hazard Ratio) was shorter for CD20 monotherapy (1.7) or chlorambucil ± CD20 (2.5). In R/R CLL, median duration was 24 (ibrutinib) and 19 months (venetoclax). Median OS was 127 months. CLLtreatment pattern shave greatly changed in Australia since the introduction of novel therapies.

Indirect influence of soil enzymes and their stoichiometry on soil organic carbon response to warming and nitrogen deposition in the Tibetan Plateau alpine meadow.

Despite extensive research on the impact of warming and nitrogen deposition on soil organic carbon components, the response mechanisms of microbial community composition and enzyme activity to soil organic carbon remain poorly understood. This study investigated the effects of warming and nitrogen deposition on soil organic carbon components in the Tibetan Plateau alpine meadow and elucidated the regulatory mechanisms of microbial characteristics, including soil microbial community, enzyme activity, and stoichiometry, on organic carbon components. Results indicated that both warming and nitrogen deposition significantly increased soil organic carbon, readily oxidizable carbon, dissolved organic carbon, and microbial biomass carbon. The interaction between warming and nitrogen deposition influenced soil carbon components, with soil organic carbon, readily oxidizable carbon, and dissolved organic carbon reaching maximum values in the W0N32 treatment, while microbial biomass carbon peaked in the W3N32 treatment. Warming and nitrogen deposition also significantly increased soil Cellobiohydrolase, ß-1,4-N-acetylglucosaminidase, leucine aminopeptidase, and alkaline phosphatase. Warming decreased the soil enzyme C: N ratio and C:P ratio but increased the soil enzyme N:P ratio, while nitrogen deposition had the opposite effect. The bacterial Chao1 index and Shannon index increased significantly under warming conditions, particularly in the N32 treatment, whereas there were no significant changes in the fungal Chao1 index and Shannon index with warming and nitrogen addition. Structural equation modeling revealed that soil organic carbon components were directly influenced by the negative impact of warming and the positive impact of nitrogen deposition. Furthermore, warming and nitrogen deposition altered soil bacterial community composition, specifically Gemmatimonadota and Nitrospirota, resulting in a positive impact on soil enzyme activity, particularly soil alkaline phosphatase and ß-xylosidase, and enzyme stoichiometry, including N:P and C:P ratios. In summary, changes in soil organic carbon components under warming and nitrogen deposition in the alpine meadows of the Tibetan Plateau primarily depend on the composition of soil bacterial communities, soil enzyme activity, and stoichiometric characteristics.

Clinical evaluation of droplet digital pcr for suspected ascites infection in patients with liver cirrhosis.

BACKGROUND: Droplet digital PCR (ddPCR) is increasingly used in diagnosing clinical pathogens, but its effectiveness in cirrhosis patients with suspected ascites infection remains uncertain. METHODS: The diagnostic performance of ddPCR was assessed in 305 ascites samples, utilizing culture and clinical composite standards. The quantitative value and potential clinical impact of ddPCR were further analyzed in patients with spontaneous bacterial peritonitis. RESULTS: With culture standards, ddPCR demonstrated a sensitivity of 86.5% and specificity of 83.2% for bacterial or fungal detection. After adjustment of clinical composite criteria, specificity increased to 96.4%. Better diagnostic performance for all types of targeted pathogens, particularly fungi, was observed with ddPCR compared to culture, and more polymicrobial infections were detected (30.4% versus 5.7%, p < 0.001). Pathogen loads detected by ddPCR correlated with white blood cell count in ascites and blood, as well as polymorphonuclear cell (PMN) count in ascites, reflecting infection status rapidly. A positive clinical impact of 55.8% (43/77) was observed for ddPCR, which was more significant among patients with PMN count ≤ 250/mm3 in terms of medication adjustment and new diagnosis. ddPCR results for fungal detection were confirmed by clinical symptoms and other microbiological tests, which could guide antifungal therapy and reduce the risk of short-term mortality. CONCLUSIONS: ddPCR, with appropriate panel design, has advantages in pathogen detection and clinical management of ascites infection, especially for patients with fungal and polymicrobial infections. Patients with atypical spontaneous bacterial peritonitis benefited more from ddPCR.

Effect of dissolved oxygen and ammonia nitrogen on Culter alburnus: Physiology, biochemistry, and molecular analyses.

Culter alburnus (topmouth culter)is an economically valuable freshwater fish. However, its insufficient tolerance to dissolved oxygen (DO) and ammonia nitrogen (AN) hinders its industrialisation. 360 experimental fish (4.87 ± 1.10 g) were placed in breathing chambers (oxygen level was 0.70-6.50 mg/L) or water tanks (control AN, 0 mg/L; low AN, 8 mg/L; high AN, 16 mg/L). This study analysed the effects of DO and AN on C. alburnus at physiological, biochemical, and molecular levels. (1) Physiology level: the floating point, coma critical point, and coma point at 20 °C group were significantly higher than those at 30 °C. The oxygen consumption rate of C. alburnus at 20 °C, 25 °C, and 30 °C was (256.65 ± 25.87), (470.47 ± 83.84), and (520.87 ± 55.40) mg/kg.h. The LC50 of AN after 96 h was 24.13 mg/L, and the safe concentration was 2.41 mg/L. The survival rate in the high AN group was significantly lower than that in the other two groups. (2) Biochemistry level: The change curves of antioxidant enzyme activity in the liver tissue under hypoxic stress reached a maximum at 12 h and then decreased. In addition, the increase and decrease in enzyme activity (except malondialdehyde) in the high AN group was lower than that in the low AN group. (3) Molecular level: the angiotensin-converting enzyme and carboxypeptidase genes were the major differentially expressed genes (DEGs) in hypoxic stress, and the DEGs were mainly enriched in the ABC transporter signal transduction pathway. In addition, the serum/glucocorticoid-regulated kinase, stearoyl-CoA desaturase, and 3-hydroxy-3-methylglutaryl-coenzyme A reductase genes were among the major DEGs under high AN stress. The DEGs were mainly enriched in steroid biosynthesis or glycine, serine, and threonine metabolism transporter signal transduction pathways. In summary, it is necessary to focus on the DO and AN during C. alburnus breeding.

REMIMAZOLAM IMPROVES THE MARKERS OF POSTRESUSCITATION CEREBRAL INJURY IN A SWINE MODEL OF CARDIAC ARREST.

ABSTRACT: Introduction: Previous studies have manifested that those sedatives acting on γ-aminobutyric acid A (GABAa) receptor could produce effective brain protection against regional and global ischemic stimulation. The present study was designed to investigate the effect of a novel GABAa receptor agonist, remimazolam postconditioning (RP) on cerebral outcome after global ischemic stimulation induced by cardiac arrest and resuscitation in swine. Methods: A total of 24 swine were used in this study, in which the animals were randomly divided into the following three groups: sham group (n = 6), cardiopulmonary resuscitation (CPR) group (n = 9), and CPR + RP group (n = 9). The experimental model was established by the procedure of 10 min of cardiac arrest and 5 min of CPR. Those resuscitated swine in the CPR + RP group received an intravenous infusion of 2.5 mg/kg of remimazolam within 60 min. Postresuscitation cerebral injury biomarkers and neurological function were evaluated for a total of 24 h. At 24 h after resuscitation, brain cortex was harvested to evaluate the severity of pathologic damage, including tissue inflammation, oxidative stress, apoptosis, and necroptosis. Results: Baseline characteristics and CPR outcomes were not significantly different between the CPR and CPR + RP groups. After resuscitation, significantly greater cerebral injury and neurological dysfunction were observed in the CPR and CPR + RP groups than in the sham group. However, remimazolam postconditioning significantly alleviated cerebral injury and improved neurological dysfunction after resuscitation when compared with the CPR group. At 24 h after resuscitation, tissue inflammation, oxidative stress, and cell apoptosis and necroptosis were significantly increased in the CPR and CPR + RP groups when compared with the sham group. Nevertheless, the severity of pathologic damage mentioned previously were significantly milder in those swine treated with the remimazolam when compared with the CPR group. Conclusions: In a swine model of cardiac arrest and resuscitation, the remimazolam administered after resuscitation significantly improved the markers of postresuscitation cerebral injury and therefore protected the brain against global ischemic stimulation.

Biologic therapy in rare eosinophil-associated disorders: remaining questions and translational research opportunities.

Rare eosinophil-associated disorders (EADs), including hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, and eosinophilic gastrointestinal disorders, are a heterogeneous group of conditions characterized by blood and/or tissue hypereosinophilia and eosinophil-related clinical manifestations. Although the recent availability of biologic therapies that directly and indirectly target eosinophils has the potential to dramatically improve treatment options for all EADs, clinical trials addressing their safety and efficacy in rare EADs have been relatively few. Consequently, patient access to therapy is limited for many biologics, and the establishment of evidence-based treatment guidelines has been extremely difficult. In this regard, multicenter retrospective collaborative studies focusing on disease manifestations and treatment responses in rare EADs have provided invaluable data for physicians managing patients with these conditions and helped identify important questions for future translational research. During the Clinical Pre-Meeting Workshop held in association with the July 2023 biennial meeting of the International Eosinophil Society in Hamilton, Ontario, Canada, the successes and limitations of pivotal multicenter retrospective studies in EADs were summarized and unmet needs regarding the establishment of guidelines for use of biologics in rare EADs were discussed. Key topics of interest included (1) clinical outcome measures, (2) minimally invasive biomarkers of disease activity, (3) predictors of response to biologic agents, and (4) long-term safety of eosinophil depletion. Herein, we report a summary of these discussions, presenting a state-of-the-art overview of data currently available for each of these topics, the limitations of the data, and avenues for future data generation through implementation of multidisciplinary and multicenter studies.

OBJECTIVE@#To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application.@*METHODS@#Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events.@*RESULTS@#Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days.@*CONCLUSIONS@#Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.

Clinical characteristics and electrogastrogram analysis of patients with functional dyspepsia overlapping lower gastrointestinal symptoms / 中国医师进修杂志

Objective:To analyze the characteristics and electrogastrogram features of patients with functional dyspepsia (FD) overlapping lower gastrointestinal symptoms (LGS).Methods:The clinical data of 61 patients with FD from January 2018 to December 2020 in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Among them, FD overlapping LGS was in 33 cases (FD overlapping LGS group), and simple FD in 28 cases (simple FD group). The manifestations of patients with FD overlapping LGS were recorded. The dyspeptic symptom score was assessed using the Rome Ⅳ criteria. Anxiety and depression status were evaluated using the hospital anxiety and depression scale (HADS), and sleep disorder was assessed using the Pittsburgh sleep quality index (PSQI). The electrogastrogram was performed, and the normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria percentage (T%), arrhythmia percentage (A%), dominant frequency, dominant power and postprandial-to-fasting power ratio (PR) were recorded.Results:The most common symptom in FD patients overlapping LGS was lower abdomen distention, the incidence was 84.85% (28/33). The upper abdominal bloating score in FD overlapping LGS group was significantly higher than that in simple FD group: 7.00 (6.50, 7.00) scores vs. 5.00 (0.50, 7.00) scores, and there was statistical difference ( P<0.01); there were no statistical differences in other dyspeptic symptoms scores and total score between the two groups ( P>0.05). The incidences of depression and sleep disorder in FD overlapping LGS group were significantly higher than those in simple FD group: 42.42% (14/33) vs. 14.29% (4/28) and 69.70% (23/33) vs. 39.29% (11/28), and there were statistical differences ( χ2 = 5.77 and 5.68, P<0.05); there was no statistical difference in the incidence of anxiety between the two groups ( P>0.05). In FD overlapping LGS group, the postprandial T% in the gastric fundus and postprandial A% in the gastric body were significantly lower than those before meal: 13.79% (6.79%, 21.46%) vs. 20.69% (12.45%, 27.59%) and 3.45% (0, 6.90%) vs. 6.90% (3.45%, 13.79%), and there were statistical differences ( P<0.01). In simple FD group, the postprandial N% in the gastric fundus was significantly lower than that before meal: 55.92% (43.71%, 70.02%) vs. 69.27% (48.07%, 78.45%), and there was statistical difference ( P<0.05). In the gastric fundus, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). In the gastric body, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the pyloric region, the PR in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the overall stomach, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, the preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). Spearman correlation analysis result showed that the disease course was not correlated with electrogastrogram parameters in patients with FD overlapping LGS ( P>0.05); the total score of dyspeptic symptoms was positively correlated with postprandial A% in the overall stomach ( r = 0.345, P<0.05), and negatively correlated with postprandial dominant frequency in the overall stomach and pyloric region ( r = -0.357 and -0.473, P<0.05 or <0.01). Conclusions:FD patients can overlap with various LGS. The patients with FD overlapping LGS have more severe dyspepsia symptoms, higher proportions of comorbid depression and sleep disorders, and more severe abnormalities in fasting proximal gastric electrical rhythm and emptying function. The severity of dyspeptic symptoms in patients with FD overlapping LGS is correlated with postprandial gastric electrical rhythm abnormalities.

New advances in stroke and cerebral embolism protection devices in transcatheter aortic valve replacement / 中国介入心脏病学杂志

Stroke is one of the most serious complications of transcatheter aortic valve replacement(TAVR),tremendously increasing mortality and the loss of neurocognitive function.Since TAVR is expected to further spread into lower-risk patient groups,there will be greater emphasis to obviate such serious complications.One possible technique for preventing stroke is using cerebral embolic protection devices(CEPDs).CEPDs are designed for capturing or deflecting emboli that are enter route to the brain and hence to protect the brain from embolism.Since this is a rapidly growing field with recent advances,and the impact of CEPD on preventing neurological events is still limited,there is an urgent need for understanding the role of CEPD in preventing clinically significant strokes.Although their clinical utilization is increasing,the risk factors for stroke related to TAVR and evidence for using CEPDs are not yet clear.In this review,we present an overview of the available literature on TAVR related stroke and CEPD,and outline recent advances within this field.

The experimental study of X-ray diagnosis of closed reduction rotational displacement of femoral neck fractures / 中华骨科杂志

Objective:To explore the optimal index of rotational displacement of femoral neck fractures by modeling the axial rotational displacement of femoral neck fractures after reduction and based on X-ray projections.Methods:Six dry human femur specimens, comprising 2 males and 4 females, were utilized in the study. Design and manufacture a proximal femur ortholateral and oblique X-ray casting jigs and mounts. The femoral neck fracture was modeled on the femoral specimen, with Pauwells 30°, 50°, and 70° models (2 each) made according to Pauwells typing. The fractures were manually repositioned with residual anterior 20°, 40° and 60° axial rotational displacements. Each fracture model was projected at different angles (pedicled 40°, pedicled 20°, vertical 0°, cephalad 20°, and cephalad 40°), and the trabecular angle and Garden's alignment index of the model were measured to observe the imaging characteristics of the fracture line on the medial oblique and lateral oblique radiographs.Results:In the presence of a 20° and 40° anterior rotational displacement following reduction of a femoral neck fracture, the trabecular angle in the rotationally displaced group was not significantly different from that of the anatomically repositioned group in various projection positions. However, when a residual rotational displacement of 60° was present, the trabeculae appeared blurred at most projection angles in the Pauwells 30° and 50° models, failing to measure trabecular angles. In the Pauwells 70° fracture model, the trabecular angle in the rotational displacement group was significantly different from that in the anatomical reduction group. In anteroposterior radiographs, when the anterior rotation displacement was 60° in the Pauwells 70° group, Garden's contralateral index showed an unsatisfactory restoration (150°, 142°), whereas all rotationally displaced models in the Pauwells 30° and Pauwells 50° groups had a Garden's contralateral index of >155°, which achieved an acceptable restoration. In lateral radiographs, all rotational displacement models with Garden's alignment index>180° failed to achieve acceptable repositioning, and the larger the Pauwells angle the greater the Garden's alignment index at the same rotational displacement. In the internal oblique position with a bias towards the foot side, the image showed partial overlap between the femoral head and the shaft, making it difficult to assess the quality of the reduction. Conversely, when projected cephalad, the femoral neck appeared longer, particularly at a projection angle of 40° cephalad, allowing for clear observation of the fracture line and the anatomy of the proximal femur. The trabeculae were not well visualized in the external oblique position.Conclusion:There are limitations in applying the trabecular angle to assess the axial rotational displacement of the femoral head after reduction of femoral neck fractures. The Pauwells 70° with residual rotational anterior displacement of 60° was the only way to detect axial rotational displacement of the femoral head on anteroposterior radiographs Garden's alignment index. For the determination of axial rotational displacement of the femoral head, the Garden's alignment index on lateral radiographs provides higher reliability.

Clinical characteristics of fungal infection in patients with infected pancreatic necrosis / 西安交通大学学报(医学版)

【Objective】 To analyze the clinical features of patients with infected pancreatic necrosis (IPN) complicated with fungal infection so as to identify possible risk factors for death. 【Methods】 We analyzed the clinical data of patients with IPN admitted to Xuanwu Hospital Capital Medical University from January 1, 2017 to December 31, 2021. According to the results of pancreatic necrotic tissue and drainage fluid culture, the patients were divided into the group with fungal infection and the group without fungal infection. The baseline data, clinical features and outcomes of the two groups were compared, and the risk factors for death in patients with fungal infection were analyzed. 【Results】 We included a total of 214 patients in the study, of whom 49 patients in the fungal infection group had wider necrotic involvement, lower hematopoietic volume, and higher blood glucose at admission. Patients with fungal infection had a higher proportion of multidrug-resistant bacteria (MDRB), and hospital and ICU stay as well as parenteral nutrition duration were also longer. In the group of patients with fungal infection, the proportion of patients undergoing surgery did not increase (P>0.05), but the proportion of patients with perioperative organ failure and death was higher (P<0.05). Candida albicans (44.8%) was the most common fungus detected, followed by Candida parapsilosis (28.6%) and Candida tropicalis (8.2%). Logistic regression analysis showed that MDRB infection (OR=1.37, 95% CI:1.02-1.83), fungemia (OR=1.53, 95% CI:1.06-2.23), hyperglycemia (OR=1.65, 95% CI:1.28-2.10), new organ failure (OR=1.65, 95% CI:1.19-2.29) and bleeding complications (OR=1.64, 95% CI:1.28-2.10) after surgery were risk factors for death in patients with fungal infection. 【Conclusion】 Fungal infection increases mortality in patients with IPN and the incidence of new organ failure after surgery. Attention to fungemia, MDRB infection, hyperglycemia, organ failure and postoperative bleeding can help reduce the risk of death.
