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.

Clinical characteristics and COVID-19-related outcomes of immunocompromised patients receiving tixagevimab/cilgavimab pre-exposure prophylaxis in Japan.

OBJECTIVE: Tixagevimab/cilgavimab is a cocktail of two long-acting monoclonal antibodies approved for pre-exposure prophylaxis (PrEP) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection (cause of coronavirus disease 2019 [COVID-19]) in immunocompromised (IC) or high-risk patients. We investigated the patient characteristics and clinical outcomes of IC patients administered tixagevimab/cilgavimab for PrEP in real-world use in Japan. METHODS: This observational study used anonymous secondary data from Real-World Data Co., Ltd. for IC patients aged ≥12 years administered tixagevimab/cilgavimab between September 2022 and September 2023. We analyzed the baseline characteristics and event-rates of COVID-19-related clinical outcomes within 6 months of administration. RESULTS: Data were analyzed for 397 IC patients. About half (53.4%) were male and the median age was 71.0 (interquartile range 61.0, 77.0) years. Malignancy (97.2%), cardiovascular disease (71.3%), and diabetes (66.5%) were frequent comorbidities. Systemic corticosteroids and immunosuppressants were prescribed to 87.4% and 24.9%, respectively. The two most common target clinical conditions were active therapy for hematologic malignancies (88.2%) and treatment with B cell-depleting therapies (57.4%). The event-rates per 100 person-months (95% confidence interval; number) for medically attended COVID-19, COVID-19 hospitalization, in-hospital mortality due to COVID-19, and all-cause death were 4.14 (3.06-5.48; n=49), 1.74 (1.09-2.64; n=22), 0.07 (0.00-0.42; n=1), and 0.60 (0.26-1.17; n=8), respectively. CONCLUSION: This is the first report using a multicenter database to describe the clinical characteristics and COVID-19-related outcomes of IC patients administered with tixagevimab/cilgavimab in real-world settings in Japan. This cohort of IC patients who received tixagevimab/cilgavimab included many elderly patients with comorbidities.

COPD Exacerbations Before and During COVID-19 in France, Germany, Italy, the UK and the US.

Background: Exacerbations of chronic obstructive pulmonary disease (COPD) were reported less frequently during the COVID-19 pandemic. We report real-world data on COPD exacerbation rates before and during this pandemic. Methods: Exacerbation patterns were analysed using electronic medical records or claims data of patients with COPD before (2017-2019) and during the COVID-19 pandemic (2020 through early 2022) in France, Germany, Italy, the United Kingdom and the United States. Data from each country were analysed separately. The proportions of patients with COPD receiving maintenance treatment were also estimated. Results: The proportion of patients with exacerbations fell 45-78% across five countries in 2020 versus 2019. Exacerbation rates in most countries were reduced by >50% in 2020 compared with 2019. The proportions of patients with an exacerbation increased in most countries in 2021. Across each country, seasonal exacerbation increases seen during autumn and winter in pre-pandemic years were absent during the first year of the pandemic. The percentage of patients filling COPD prescriptions across each country increased by 4.53-22.13% in 2019 to 9.94-34.17% in 2021. Conclusion: Early, steep declines in exacerbation rates occurred in 2020 versus 2019 across all five countries and were accompanied by a loss of the seasonal pattern of exacerbation.

Assessment of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and other antidiabetic agents in Alzheimer's disease: a population-based study.

The lack of effective treatments for dementia has led to explore the potential of antidiabetic agents as a possible approach. This cross-sectional and population-based study aimed to investigate the relationship between each antidiabetic drug and their defined daily doses (DDDs) and the use of anti-Alzheimer's disease (AD) drugs in order to establish new possible hypotheses about the role of antidiabetic drugs in AD. For that purpose, a database containing information on medications prescribed to 233183 patients aged 50 years or older between 2018 and 2020 was used. DDDs were calculated according to the ATC/DDD index 2023. Statistical analyses, with logistic regression, were carried out to assess antidiabetic and anti-AD drugs consumption. A total of 91836 patients who were prescribed at least one antihypertensive, antidiabetic, or lipid-modifying agent were included in the study; specifically, 29260 patients were prescribed antidiabetic medication. Among the antidiabetic agents, glucagon-like peptide-1 analogs (GLP-1) DDDs were likely to have a positive association with anti-AD drugs in people aged between 70 and 80 years. Additionally, sodium-glucose cotransporter 2 inhibitors (SGLT2i) were prone to have a positive association with anti-AD drug usage across almost every age. However, insulin usage was associated with an increased usage of anti-AD agents. In conclusion, there is evidence suggesting a correlation between certain antidiabetic agents and dementia. Specifically, GLP-1 and SGLT2i might be associated with lower odds of anti-AD drugs usage, while insulins might be linked to higher odds of using anti-AD drugs.

Impact and implications of national centralized drug procurement in China.

The national centralized drug procurement (NCDP) policy, known as the "4 + 7" policy in China, has transformed pharmaceutical procurement and access by leveraging healthcare institutions' collective buying power to reduce drug prices substantially. This policy has profoundly impacted drug pricing mechanisms, healthcare expenditures, market dynamics, and the quality of available drugs. This commentary evaluates the efficacy, challenges, and broader implications of the NCDP, summarizes the current state of post-marketing monitoring of selected generic drugs for centralized procurement, and presents relevant considerations.

Cost analysis of radical resection of malignant breast tumors under the China Healthcare Security Diagnosis Related Groups payment system.

BACKGROUND: Breast cancer is one of the most common malignant tumors in women worldwide and poses a severe threat to their health. Therefore, this study examined patients who underwent breast cancer surgery, analyzed hospitalization costs and structure, and explored the impact of China Healthcare Security Diagnosis Related Groups (CHS-DRG) management on patient costs. It aimed to provide medical institutions with ways to reduce costs, optimize cost structures, reduce patient burden, and improve service efficiency. AIM: To study the CHS-DRG payment system's impact on breast cancer surgery costs. METHODS: Using the CHS-DRG (version 1.1) grouping criteria, 4073 patients, who underwent the radical resection of breast malignant tumors from January to December 2023, were included in the JA29 group; 1028 patients were part of the CHS-DRG payment system, unlike the rest. Through an independent sample t-test, the length of hospital stay as well as total hospitalization, medicine and consumables, medical, nursing, medical technology, and management expenses were compared. Pearson's correlation coefficient was used to test the cost correlation. RESULTS: In terms of hospitalization expenses, patients in the CHS-DRG payment group had lower medical, nursing, and management expenses than those in the diagnosis-related group (DRG) non-payment group. For patients in the DRG payment group, the factors affecting the total hospitalization cost, in descending order of relevance, were medicine and consumable costs, consumable costs, medicine costs, medical costs, medical technology costs, management costs, nursing costs, and length of hospital stay. For patients in the DRG non-payment group, the factors affecting the total hospitalization expenses in descending order of relevance were medicines and consumable expenses, consumable expenses, medical technology expenses, the cost of medicines, medical expenses, nursing expenses, length of hospital stay, and management expenses. CONCLUSION: The CHS-DRG system can help control and reduce unnecessary medical expenses by controlling medicine costs, medical consumable costs, and the length of hospital stay while ensuring medical safety.

Diabetes Technology and Waste: A Real-World Study in a Specialized Practice in Germany.

BACKGROUND: Diabetes technology is a fundamental part of modern diabetes therapy. Its widespread usage is associated with an increasing amount of "diabetes technology waste." The aim of this study was to quantify this waste in a real-world situation in a specialized diabetes practice in Germany. METHODS: Eighty patients with diabetes and insulin treatment participated and collected all of their therapy-associated waste for three months. Their attitude toward sustainability of antidiabetic therapy, waste generation, and their own waste reduction/separation behavior was surveyed. RESULTS: In total, 23 707 pieces of therapy-associated waste were collected. They comprised 5362 test strips, 630 glucose sensors, 14 619 needles, 519 insulin cartridges, 599 pens, and 1463 pieces of aids for insulin pump therapy. Type and quantity of the collected waste depended on the type of diabetes and the respective therapy, ie, multiple daily injections, usage of glucose sensors, or pump therapy. Most participants (92%) were surprised by the amounts of waste and reported an increased awareness toward the resource consumption of their therapy (87%). The survey indicated an enhanced interest in waste separation (94%) and a demand for the reduction and recycling of devices/aids (93%). CONCLUSIONS: Our data revealed the amount and complexity of the waste generated by modern diabetes therapy. Extrapolating these data, it can be estimated that around 1.2 billion pieces of diabetes technology waste are generated in Germany per year. The major concern of the study participants was the limited number of recycling options. A clear demand for improved sustainability of the medical products was expressed.

Comparison of the efficacy and safety of domestically produced tislelizumab, camrelizumab, and imported pembrolizumab in the treatment of advanced NSCLC: a real-world retrospective study.

BACKGROUND: Since the imported PD-1 inhibitor pembrolizumab was listed in China in 2018, China has opened up the era of immunotherapy for malignant tumors, with several domestically produced PD-1 inhibitors coming onto the market one after another. To find out whether there are differences in the efficacy and safety of domestic and imported PD-1 inhibitors in patients with advanced non-small cell lung cancer, we conducted this retrospective study in two tertiary hospitals in China. METHODS: Patients with advanced NSCLC treated with tislelizumab or camrelizumab or pembrolizumab who met the inclusion criteria were screened through the electronic medical record system. A total of 259 patients were screened, but due to the unbalanced baseline, we performed propensity score matching and finally included 149 patients in three groups: pembrolizumab (n = 38), tislelizumab (n = 38), and camrelizumab (n = 73), which had very balanced baseline characteristics in each group after propensity score matching treatment. RESULTS: The results showed that the median progression-free period was 11.3 m vs 10.1 m vs 8.9 m; p = 0.754; and the objective response rate was 63.2% vs 50% vs 57.5%; P = 0.510 for pembrolizumab, tislelizumab, and carrelizumab, respectively. There was no significant difference in median PFS between PD-L1 expression subgroups. In terms of safety, only skin toxicity of any grade of carrelizumab was higher than that of the other two groups (p = 0.034), and the incidence of grade ≥ 3 adverse reactions was not statistically significant among the three groups. CONCLUSION: In this real-world study, the efficacy and safety of the domestically produced tislelizumab, camrelizumab, and the imported pembrolizumab were comparable.

[Cardiovascular safety of sitagliptin added to metformin in real world patients with type 2 diabetes].

OBJECTIVE: To assess the safety of sitagliptin added to metformin on cardiovascular adverse events in real world patients with type 2 diabetes mellitus (T2DM). METHODS: Real world data from Yinzhou Regional Health Care Database were used to select T2DM patients with diagnosis and treatment records in the platform from January 1, 2017 to December 31, 2022. According to drug prescription records, the patients were divided into metformin plus sitagliptin group (combination group) and metformin monotherapy group(monotherapy group). A series of retrospective cohorts were constructed according to the index date.Finally, full retrospective cohorts were constructed according to propensity score model, including baseline covariates that might be related to outcomes, to match the subjects in the combination group and monotherapy group for the purpose of increasing the comparability of baseline characteristics. The participants were followed up from the index date until the first occurrence of the following events: Diagnosis of outcomes, death, or the end of the study period (December 31, 2022). Cox proportional risk model was used to estimate the hazard ratio(HR)and 95% confidence interval (CI) of sitagliptin added to metformin on 3-point major adverse cardiovascular events (3P-MACE) combination outcome and secondary cardiovascular outcomes. RESULTS: Before propensity score matching, the proportion of the patients in combination group using insulin, α glucosidase inhibitors, sodium-glucose transporter 2 inhibitors (SGLT-2I) and glienides at baseline was higher than that in monotherapy group, and the baseline fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels in combination group were higher than those in monotherapy group. After propensity score matching, 5 416 subjects were included in the combination group and the monotherapy group, and baseline characteristics were effectively balanced between the groups. The incidence densities of 3P-MACE were 6.41/100 person years and 6.35/100 person years, respectively. Sitagliptin added to metformin did not increase or decrease the risk of 3P-MACE compared with the metformin monotherapy (HR=1.00, 95% CI: 0.91-1.10). In secondary outcomes analysis, the incidence of cardiovascular death was lower in the combination group than in the monotherapy group (HR=0.59, 95% CI: 0.41-0.85), and no association was found between sitagliptin and the risk of myocardial infarction and stroke (HR=1.12, 95% CI: 0.89-1.41; HR=0.99, 95% CI: 0.91-1.12). CONCLUSION: In T2DM patients in Yinzhou district of Ningbo, compared with metformin alone, sitagliptin added to metformin may reduce the risk of cardiovascular death, and do not increase the incidence of overall cardiovascular events. The results of this study can provide real-world evidence for post-marketing cardiovascular safety evaluation of sitagliptin.

Extemporaneous combination therapy with nebivolol/ramipril for the treatment of hypertension: a real-world evidence study in Europe.

OBJECTIVES: To describe the clinical characteristics and treatment adherence in European adult hypertensive patients starting treatment with the extemporaneous combination of nebivolol and ramipril (NR-EXC). METHODS: Retrospective database analysis of patients receiving NR-EXC treatment across five European countries (Italy, Germany, France, Poland, Hungary) over a period ranging from 3 to 9 years (until 30 June 2020) according to data availability for the different data sources. Patient demographics, comorbidities, and treatment adherence were evaluated. RESULTS: We identified 592,472 patients starting NR-EXC. Most of them were over 60 years of age, with ramipril most commonly prescribed at 5 mg (from 30.0 to 57.2% of patients across the databases). Notable comorbidities included diabetes (19.2%) and dyslipidemia (18.2%). The study population was also highly subjected to polytherapy with antithrombotics, lipid-lowering agents, and other lowering blood pressure agents as the most co-prescribed medications, as resulted from Italian database. Up to 59% of the patients did not request a cardiologic visit during the study period. Adherence to therapy was low in 56.3% of the patients, and it was high only in 11.1% of them. CONCLUSIONS: The combination of nebivolol and ramipril is frequently prescribed in Europe, but adherence to treatment is suboptimal. The transition to a single pill combination could enhance treatment adherence and streamline regimens, potentially leading to significant benefits. Improved adherence not only correlates with better blood pressure control but also reduces the risk of cardiovascular events, underscoring the importance of this development.

Early Detection of 5 Neurodevelopmental Disorders of Children and Prevention of Postnatal Depression With a Mobile Health App: Observational Cross-Sectional Study.

BACKGROUND: Delay in the diagnosis of neurodevelopmental disorders (NDDs) in toddlers and postnatal depression (PND) is a major public health issue. In both cases, early intervention is crucial but too rarely implemented in practice. OBJECTIVE: Our goal was to determine if a dedicated mobile app can improve screening of 5 NDDs (autism spectrum disorder [ASD], language delay, dyspraxia, dyslexia, and attention-deficit/hyperactivity disorder [ADHD]) and reduce PND incidence. METHODS: We performed an observational, cross-sectional, data-based study in a population of young parents in France with at least 1 child aged <10 years at the time of inclusion and regularly using Malo, an "all-in-one" multidomain digital health record electronic patient-reported outcome (PRO) app for smartphones. We included the first 50,000 users matching the criteria and agreeing to participate between May 1, 2022, and February 8, 2024. Parents received periodic questionnaires assessing skills in neurodevelopment domains via the app. Mothers accessed a support program to prevent PND and were requested to answer regular PND questionnaires. When any PROs matched predefined criteria, an in-app recommendation was sent to book an appointment with a family physician or pediatrician. The main outcomes were the median age of the infant at the time of notification for possible NDD and the incidence of PND detection after childbirth. One secondary outcome was the relevance of the NDD notification by consultation as assessed by health professionals. RESULTS: Among 55,618 children median age 4 months (IQR 9), 439 (0.8%) had at least 1 disorder for which consultation was critically necessary. The median ages of notification for probable ASD, language delay, dyspraxia, dyslexia, and ADHD were 32.5 (IQR 12.8), 16 (IQR 13), 36 (IQR 22.5), 80 (IQR 5), and 61 (IQR 15.5) months, respectively. The rate of probable ADHD, ASD, dyslexia, language delay, and dyspraxia in the population of children of the age included between the detection limits of each alert was 1.48%, 0.21%, 1.52%, 0.91%, and 0.37%, respectively. Sensitivity of alert notifications for suspected NDDs as assessed by the physicians was 78.6% and specificity was 98.2%. Among 8243 mothers who completed a PND questionnaire, highly probable PND was detected in 938 (11.4%), corresponding to a reduction of -31% versus our previous study without a support program. Suspected PND was detected a median 96 days (IQR 86) after childbirth. Among 130 users who filled in the satisfaction survey, 99.2% (129/130) found the app easy to use and 70% (91/130) reported that the app improved follow-up of their child. The app was rated 4.8/5 on Apple's App Store. CONCLUSIONS: Algorithm-based early alerts suggesting NDDs were highly specific with good sensitivity as assessed by real-life practitioners. Early detection of 5 NDDs and PNDs was efficient and led to a possible 31% reduction in PND incidence.

Indirect comparison of capmatinib treatment from GEOMETRY mono-1 trial to SOC in German patients with locally advanced or metastatic NSCLC harboring METex14 skipping mutations.

BACKGROUND: This study provides comparative evidence of the selective MET inhibitor capmatinib versus standard of care (SOC) in first-line (1 L) and second-line (2 L) non-small cell lung cancer (NSCLC) patients with METex14 mutations in German routine care. METHODS: SOC data were collected from German routine care via retrospective chart review. Analyses were conducted as naive and propensity score adjusted (PSA) comparisons to capmatinib-treated patients within the GEOMETRY mono-1 trial. Effectiveness endpoints included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), time to CNS progression (CNSprog), and exploratory safety endpoints. RESULTS: The SOC arm included 119 patients in 1 L and 46 in 2 L versus 60 patients in 1 L and 81 in 2 L treated with capmatinib, with balanced baseline characteristics after PSA. In 1 L, the naive comparison showed a significant benefit of capmatinib versus SOC for OS (median: 25.49 vs 14.59 months; HR 0.58; 95 % CI 0.39-0.87; P = 0.011), PFS (median: 12.45 vs 5.03 months; HR: 0.44; 95 % CI: 0.31-0.63; P < 0.001), and ORR (event rate: 68.3 vs 26.9 %; RR 2.54; 95 % CI 1.80-3.58; P < 0.001). In 2 L, OS, PFS, and ORR showed positive trends favoring capmatinib over SOC. Capmatinib treatment in the 1 L and 2 L led to significant benefit in CNSprog. PSA analyses showed consistent results to naive analysis. Exploratory safety endpoints indicated a manageable safety profile for capmatinib. CONCLUSIONS: The present study demonstrates the important role of capmatinib in providing robust clinically meaningful benefit to patients with NSCLC harboring METex14 mutations and its significant role in preventing the development of brain metastases.

Progression patterns, resistant mechanisms and subsequent therapy for ALK-positive NSCLC in the era of second-generation ALK-TKIs.

BACKGROUND: In the era of second-generation ALK tyrosine kinase inhibitors (ALK-TKIs), there was a paucity of data regarding the progression patterns, resistant mechanisms, and subsequent therapeutic approaches for ALK-positive (ALK+) non-small cell lung cancer (NSCLC). METHODS: Patients with advanced ALK+ NSCLC were retrospectively selected from our center. Cohort 1 consisted of patients who experienced disease progression after receiving first-line alectinib treatment (n = 20), while Cohort 2 included patients who progressed following sequential treatment with crizotinib and second-generation ALK-TKIs (n = 53). Oligo-progression was defined as the occurrence of disease progression in no more than three lesions. Symptomatic progression was determined when patients developed new symptoms or experienced worsening of pre-existing symptoms during radiological progression. RESULTS: The incidence of central nervous system (CNS) progression and symptomatic CNS progression was significantly lower in Cohort 1 compared to patients treated with crizotinib, with rates of 15.0% vs. 56.6% (p = 0.002) and 5.0% vs. 32.1% (p = 0.016), respectively. A total of 60.3% (44/73) patients underwent repeated biopsy and next-generation sequencing subsequent to the second-generation ALK-TKI resistance, with secondary mutation in ALK kinase domain emerging as the predominant mechanism of resistance (56.8%). Local therapy was applied to 50% of oligo-progression cases. Subsequent ALK-TKIs demonstrated significantly prolonged progression-free survival (PFS) (8.6 m vs. 2.7 m, p = 0.021, HR = 0.43, 95%CI: 0.15-0.85) and long-term overall survival (OS) (NA vs. 11.9 m, p = 0.132, HR = 0.50, 95%CI: 0.18-1.25) in patients harboring ALK resistance mutations, compared to those without such mutations. For patients without ALK-resistant mutations following progression on second-generation ALK-TKIs, there was no statistically significant difference in survival outcomes between subsequent chemotherapy or alternative ALK-TKI treatments. CONCLUSIONS: First-line alectinib demonstrated superior efficacy in protecting the CNS compared to crizotinib. For patients with ALK-resistant mutations following the resistance to second-generation ALK-TKIs, appropriate sensitive ALK-TKI should be administered; for those without such mutations, the selection of chemotherapy or third-generation ALK-TKI should be based on the patient's overall physical health and personal preferences.

Tyrosine kinase inhibitors in HER2-positive metastatic breast cancer with trastuzumab emtansine resistance: insights from a multicenter retrospective real-world study.

The use of trastuzumab emtansine (T-DM1) has revealed significant efficacy in HER2-positive metastatic breast cancer (MBC). However, optimal therapeutic strategies following T-DM1 failure remain a subject of debate in clinical practice. In this multicenter, retrospective, real-world study, we sought to examine the effectiveness and safety of tyrosine kinase inhibitors (TKIs) as a therapeutic strategy in HER2-positive MBC who developed T-DM1 resistance. Between September 2018 and December 2022, 66 patients were enrolled. The median progression-free survival of TKIs-based therapy was 10.1 months (95% CI, 4.7-15.6). Objective response rate and clinical benefit rate were 18.2 and 66.7%, respectively. TKIs-based therapy demonstrated better effectiveness in patients who had previously derived benefit from T-DM1 and featured acquired resistance to trastuzumab. The most common adverse events were diarrhea (36, 54.5%), hand-foot syndrome (31, 47.0%), and leucopenia (30, 45.5%). In conclusion, TKIs-based therapy showed promising effectiveness and safety in HER2-positive MBC patients after T-DM1 failure.

Molecular mechanism of the treatment of lung adenocarcinoma by Hedyotis Diffusa: an integrative study with real-world clinical data and experimental validation.

Background: With a variety of active ingredients, Hedyotis Diffusa (H. diffusa) can treat a variety of tumors. The purpose of our study is based on real-world data and experimental level, to double demonstrate the efficacy and possible molecular mechanism of H. diffusa in the treatment of lung adenocarcinom (LUAD). Methods: Phenotype-genotype and herbal-target associations were extracted from the SymMap database. Disease-gene associations were extracted from the MalaCards database. A molecular network-based correlation analysis was further conducted on the collection of genes associated with TCM and the collection of genes associated with diseases and symptoms. Then, the network separation SAB metrics were applied to evaluate the network proximity relationship between TCM and symptoms. Finally, cell apoptosis experiment, Western blot, and Real-time PCR were used for biological experimental level validation analysis. Results: Included in the study were 85,437 electronic medical records (318 patients with LUAD). The proportion of prescriptions containing H. diffusa in the LUAD group was much higher than that in the non-LUAD group (p < 0.005). We counted the symptom relief of patients in the group and the group without the use of H. diffusa: except for symptoms such as fatigue, palpitations, and dizziness, the improvement rate of symptoms in the user group was higher than that in the non-use group. We selected the five most frequently occurring symptoms in the use group, namely, cough, expectoration, fatigue, chest tightness and wheezing. We combined the above five symptom genes into one group. The overlapping genes obtained were CTNNB1, STAT3, CASP8, and APC. The selection of CTNNB1 target for biological experiments showed that the proliferation rate of LUAD A549 cells in the drug intervention group was significantly lower than that in the control group, and it was concentration-dependent. H. diffusa can promote the apoptosis of A549 cells, and the apoptosis rate of the high-concentration drug group is significantly higher than that of the low-concentration drug group. The transcription and expression level of CTNNB1 gene in the drug intervention group were significantly decreased. Conclusion: H. diffusa inhibits the proliferation and promotes apoptosis of LUAD A549 cells, which may be related to the fact that H. diffusa can regulate the expression of CTNNB1.

Real-world assessment of anaphylaxis and eosinophilic esophagitis with 12 SQ house dust mite SLIT-tablet sublingual immunotherapy.

Background: Sublingual immunotherapy (SLIT) with 12 SQ house dust mile SLIT-tablet (HDM SLIT-tablet) for dust mite-induced perennial allergic rhinitis is reported as effective and safe. Although serious allergic reactions (SARs) and eosinophilic esophagitis (EoE) have infrequently occurred under trial conditions, the safety of HDM SLIT-tablet challenge under real-world conditions is unknown. Objective: Our aim was to estimate the incidence of SARs and EoE due to HDM SLIT-tablet challenge. Methods: Through use of administrative data from Kaiser Permanente Southern California, this prospective observational study identified patients newly administered HDM SLIT-tablet with follow-up until SLIT discontinuation or end of study. Suspected cases of SARs and EoE were detected by using International Classification of Diseases, 10th Revision, diagnosis and Current Procedural Terminology procedure codes and medication dispensing records. A 3-member clinical review committee of allergists adjudicated suspected reactions. The incidence rate of confirmed SARs and EoE per 1000 person years of exposure were determined. Results: A total of 521 patients (93.9% adult and 6.1% pediatric) were exposed to HDM SLIT-tablet challenge from January 2018 through May 2023, for 440.4 person years of exposure. The patients' average age (SD) was 39.3 (14.1) years, 58.7% were female, 44.3% were non-Hispanic White, 40.3% had asthma, and 15.0% had gastroesophageal reflux disease. A SAR occurred in 1 adult patient, and during initial HDM SLIT-tablet challenge, SARs occurred in 2 pediatric adolescents, for an overall incidence of 6.8 SARs per 1000 patient years (95% CI = 2.2-21.1). EoE occurred in 1 adult patient, for an overall incidence of 2.3 cases of EoE per 1000 patient years (95% CI = 0.3-16.1). Conclusions: This real-world study demonstrated that SARs and EoE were infrequent events with HDM SLIT-tablet use, supporting the safety of HDM SLIT-tablets and need for physician supervision with initial challenge.

[Treatment status of tyrosine kinase inhibitor for newly-diagnosed chronic myeloid leukemia: a domestic multi-centre retrospective real-world study].

Objective: To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China. Methods: Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed. Results: 6 893 patients in CP (n=6 453, 93.6%) or AP (n=440, 6.4%) receiving initial imatinib (n=4 906, 71.2%), nilotinib (n=1 157, 16.8%), dasatinib (n=298, 4.3%) or flumatinib (n=532, 7.2%) -therapy. With the median follow-up of 43 (IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance (n=1 055, 15.3%), intolerance (n=248, 3.6%), pursuit of better efficacy (n=168, 2.4%), economic or other reasons (n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph(+) ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph(+) ACA, poorer TFS; Ph(+) ACA, poorer OS. Conclusion: At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Evaluating Oral Probiotic Supplements as Complementary Treatment in Advanced Lung Cancer Patients Receiving ICIs: A Prospective Real-World Study.

OBJECTIVE: To evaluate the effectiveness of oral probiotic supplements in patients undergoing immune checkpoint inhibitors (ICIs) for the treatment of advanced lung cancer. METHODS: This prospective real-world study enrolled patients with advanced lung cancer who were receiving ICIs as part of their treatment. The patients were divided into 2 groups: Group OPS received oral probiotic supplements along with ICIs, while Group C did not. The primary endpoint was progression-free survival (PFS). The secondary outcome measure was the objective response rate (ORR). RESULTS: A total of 253 patients were included in the study, with 71 patients in Group OPS and 182 patients in the control group (Group C). No significant differences were observed in the median PFS between the 2 groups for all patients. However, for small cell lung cancer (SCLC) patients, the median PFS was significantly better in the Group OPS compared to the Group C (11.1 months vs 7.0 months, P = .049). No significant differences were observed in median PFS for the non-small cell lung cancer (NSCLC) cohort between the 2 groups, but a trend towards better median PFS in Group OPS was noticed (16.5 months vs 12.3 months, P = .56). The ORR for the entire cohort was 58.0%. CONCLUSION: Oral probiotics supplements in combination with ICIs included regimen may improve the outcome in patients with advanced SCLC. The above points should be proved by further study.

This study examined whether the addition of oral probiotic supplements to ICIs could enhance the treatment of advanced lung cancer. A total of 253 patients with advanced lung cancer were involved in the study, with some receiving probiotics in combination with ICIs and others not. The findings revealed that patients with SCLC who took probiotics had significantly better PFS compared to those who did not. Additionally, there was a tendency towards enhanced PFS in NSCLC patients who received probiotics. In conclusion, the study indicates that incorporating oral probiotics with ICIs may lead to better outcomes for patients with advanced SCLC, although further research is necessary to validate these results.This real world study explores whether oral probiotic supplements along with immune checkpoint inhibitors (ICIs) can help treat advanced lung cancer. The study included 253 patients with advanced lung cancer receiving ICIs treatment, part of them taking probiotics along with ICIs. The results showed that patients with small cell lung cancer (SCLC) who took probiotics had better progression-free survival (PFS) compared to those who didn't. There was also a trend towards better PFS in non-small cell lung cancer (NSCLC) patients who took probiotics. Overall, the study suggests that taking oral probiotics along with ICIs may improve outcomes for patients with advanced SCLC, but more research is needed to confirm these findings.
