RESUMO

INTRODUCTION: Wound irrigation has been employed as an important surgical step to remove bacteria, devitalized tissues, and foreign bodies from surgical sites to prevent infection and confer to the wound maximum potential of healing. METHOD: A prospective study was conducted at Federal Medical Centre, Gusau, between January 2019- August 2023 to assess the benefit of antibiotics as additives in irrigation of dirty wounds. Seven (7) patients in total were presented with severe cut-throat injuries that require laryngopharyngoplasty. A combination of injection ciprofloxacin and metronidazole were used as additives into 1 L of normal saline, low pressure irrigation was done using 20mls syringe fitted to a broken needle or canular. Dysphagia Outcome and Severity Scale (DOSS) was used to assess return of pharyngeal function. RESULT: The mean time of presentation of the patients was 34 ± 29 h (µ ± standard deviation) and a range of 6-72 h. The mean repair time was 58.3 ± 38.4 h with a range of 24-120 h. Most of the patients (85.7 %) had dysphagia outcome and severity scale of level 5 when per oral feeding was started with steady progress until discharge day. CONCLUSION: Wound irrigation is one of the most crucial steps in treating severe cut-throat injuries. Based on our experience, adding antibiotics to the irrigant has shown potential in the control of local infection, particularly where patients present late.

RESUMO

OBJECTIVE: Early clot removal using endovascular intervention aims to reduce post-thrombotic syndrome (PTS) following iliofemoral deep venous thrombosis (DVT). This may reduce long term morbidity but incurs a higher initial cost. This study examined the cost effectiveness of catheter directed thrombolysis (CDT) and pharmacochemical thrombectomy (PMT) compared with oral anticoagulation (OAC) alone for treatment of acute iliofemoral DVT in the United Kingdom. METHODS: A combined decision tree (acute DVT complications) and Markov model (long term complications [PTS]) was used for decision analytic modelling with five states: no PTS, mild PTS, moderate PTS, severe PTS, and dead. All patients started with acute DVT. Patients who survived acute complications transitioned into the Markov model. Cycle time was six months. A healthcare payer perspective and lifetime horizon was used, adjusting for excess mortality due to history of thrombosis. Data for probabilities, transition probabilities, mortality, and utilities were obtained from the published literature. Cost data were obtained from UK NHS tariffs and published literature. Outcomes were mean lifetime cost, quality adjusted life years (QALYs), and cost effectiveness. RESULTS: Over a patient's lifetime, OAC was more costly (£37 206) than CDT (£32 043) and PMT (£36 288). Mean lifetime QALYs for OAC (12.9) were lower than CDT (13.5) and PMT (13.3). Therefore, in the incremental cost effectiveness analysis, both CDT and PMT were dominant: CDT was less costly (-£5 163) and more effective (+0.6 QALYs) than OAC, and PMT was also less costly (-£917) and more effective (+0.3 QALYs) than OAC. Results were robust to univariable sensitivity analyses, but probabilistic sensitivity analyses suggested considerable parameter uncertainty. CONCLUSION: Early interventional treatment of iliofemoral DVT is cost effective in the UK. Future clinical and epidemiological studies are needed to characterise parameter uncertainty. Further analysis of modern practice, alternative treatments, and optimised care models is warranted.

RESUMO

OBJECTIVES: The purpose of this study was to describe the frequency of arrhythmias detected in unsedated feline patients from general practice settings. ANIMALS: A total 10,638 feline electrocardiograms (ECGs) were retrospectively collected of which 9440 met the inclusion criteria. METHODS: Recordings were evaluated by a board-certified cardiologist. If an arrhythmia was present in the ECG tracing, the cardiologist categorized the arrhythmia using pre-established keywords. RESULTS: At least one arrhythmia was observed in 249 cases (2.64%, 95% confidence interval (CI): 2.34-2.98, 249/9440), with the most common arrhythmia encountered being ventricular premature complexes (1.63%, 95% CI: 1.39%-1.91%, 154/9440). Ragdoll cats had the highest odds of arrhythmia (odds ratio (OR): 3.17, 95% CI: 1.43-6.17, P=0.036). Both geriatric (Age: 13+ years, OR: 1.70, 95% CI: 1.24-2.34, P=0.013) and senior (Age: 10-13 years, OR: 1.68, 95% CI: 1.19-2.37, P=0.003) cats had higher odds of having an arrhythmia than adult cats. The odds of male cats having an arrhythmia were slightly higher than female (OR: 1.36, 95% CI: 1.06-1.76, P=0.018). CONCLUSIONS AND RELEVANCE: Of the 9440 ECGs included in this study, at least one arrhythmia was detected in 249 distinct cases. Arrhythmias were more common in older cats, male cats and the Ragdoll cat breed. While it is important to note that the presence of an arrhythmia alone does not always indicate the presence of heart disease, further research on the association between breed cardiac health is needed.

RESUMO

OBJECTIVES: The vertebral heart score is a measurement used to index heart size relative to thoracic vertebra. Vertebral heart score can be a useful tool for identifying and staging heart disease and providing prognostic information. The purpose of this study is to validate the use of a vertebral heart score algorithm compared to manual vertebral heart scoring by three board-certified veterinary cardiologists. MATERIALS AND METHODS: A convolutional neural network centred around semantic segmentation of relevant anatomical features was developed to predict heart size and vertebral bodies. These predictions were used to calculate the vertebral heart score. An external validation study consisting of 1200 canine lateral radiographs was randomly selected to match the underlying distribution of vertebral heart scores. Three American College of Veterinary Internal Medicine board-certified cardiologists were enrolled to manually score 400 images each using the traditional Buchanan method. Post-scoring, the cardiologists evaluated the algorithm for misaligned anatomic landmarks and overall image quality. RESULTS: The 95th percentile absolute difference between the cardiologist vertebral heart score and the algorithm vertebral heart score was 1.05 vertebrae (95% confidence interval: 0.97 to 1.20 vertebrae) with a mean bias of -0.09 vertebrae (95% confidence interval: -0.12 to -0.05 vertebrae). In addition, the model was observed to be well calibrated across the predictive range. CLINICAL SIGNIFICANCE: We have found the performance of the vertebral heart score algorithm comparable to three board-certified cardiologists. While validation of this vertebral heart score algorithm has shown strong performance compared to veterinarians, further external validation in other clinical settings is warranted before use in those settings.

RESUMO

BACKGROUND: Immune checkpoint inhibitors, such as pembrolizumab, nivolumab, and atezolizumab, have demonstrated substantial survival benefits in patients with advanced non-small cell lung cancer (NSCLC). However, there is limited evidence on their relative safety profiles and adverse event (AE)-related cost burden. OBJECTIVE: To compare the AE management costs of nivolumab plus ipilimumab with and without limited chemotherapy with those of chemotherapy, pembrolizumab plus chemotherapy, and atezolizumab plus chemotherapy in a first-line setting among patients with advanced NSCLC. METHODS: The mean per-patient AE costs were estimated using the incidence of all-cause grade 3/4 AEs with any-grade incidence greater than or equal to 15% and the corresponding costs of AE management in the inpatient setting. AE rates were obtained from individual patient data from the CheckMate 227 and CheckMate 9LA trials for nivolumab plus ipilimumab with/without limited chemotherapy and aggregated data from the KEYNOTE-189 and KEYNOTE-407 trials for pembrolizumab plus chemotherapy and the IMpower130 trial for atezolizumab plus chemotherapy. AE management costs from the third-party payer perspective were estimated based on inpatient medical costs from the 2016 United States Healthcare Cost and Utilization Project National Inpatient Sample. All costs were inflated to 2020 US dollars. RESULTS: Nivolumab plus ipilimumab and nivolumab plus ipilimumab plus limited chemotherapy were associated with lower per-patient grade 3/4 AE costs compared with chemotherapy ($1,708 and $624 lower over the treatment course, respectively). Compared with pembrolizumab plus chemotherapy, nivolumab plus ipilimumab was associated with lower grade 3/4 AE costs in patients with nonsquamous histology (difference: -$4,866) and squamous histology (difference: -$3,795), and nivolumab plus ipilimumab with limited chemotherapy also had lower AE costs for both nonsquamous (difference: -$2,800) and squamous (difference: -$2,753) disease. Similarly, nivolumab plus ipilimumab and nivolumab plus ipilimumab plus limited chemotherapy were also associated with lower AE costs ($11,400 and $8,809 lower, respectively) compared with atezolizumab plus chemotherapy among patients with nonsquamous disease. In particular, nivolumab plus ipilimumab without or with limited chemotherapy were associated with much lower AE costs of hematological AEs compared with chemotherapy and other immune checkpoint inhibitor-based treatments in combination with a full course of chemotherapy. CONCLUSIONS: Nivolumab plus ipilimumab with/without limited chemotherapy was associated with lower AE management costs compared with chemotherapy, pembrolizumab plus chemotherapy, and atezolizumab plus chemotherapy as first-line treatment for advanced NSCLC. The AE cost benefits were largely driven by the lower cost burden for hematological AEs for nivolumab plus ipilimumab with/without limited chemotherapy.

RESUMO

A 6-year-old female spayed Chihuahua mix presented with chronic recurrent ascites. Computed tomographic angiography revealed an isolated stenosis of the caudal vena cava secondary to a metallic foreign body, resulting in Budd-Chiari-like syndrome. Balloon angioplasty and endovascular stent placement successfully resolved the obstruction with long-term resolution of ascites.

RESUMO

OBJECTIVES: Recent advances have created options for first-line (1L) treatment of advanced/metastatic non-small cell lung cancer (aNSCLC). The study objectives were to describe the utilization of 3 classes of 1L treatment-chemotherapy (CT), immunotherapy (IO), and chemoimmunotherapy (IO+CT)-and the total, third-party payer, direct health care costs. STUDY DESIGN: Retrospective, administrative claims database analysis of patients with aNSCLC who initiated 1L treatment between January 1, 2017, and May 31, 2019, with IO, CT, or IO+CT. METHODS: Microcosting enumerated health care resource utilization, including antineoplastic drug costs, using standardized costs. Generalized linear models estimated per-patient per-month (PPPM) costs during 1L treatment, and adjusted cost differences in 1L among treatment cohorts were calculated using recycled predictions. RESULTS: A total of 1317 IO-, 5315 CT-, and 1522 IO+CT-treated patients were identified. Utilization of CT declined from 72.3% to 47.6% between 2017 and 2019, replaced by use of IO+CT, which increased from 1.8% to 29.8%. Total PPPM costs in 1L were highest with IO+CT at $32,436, compared with $19,000 and $17,763 in the CT and IO cohorts, respectively. Adjusted analyses showed that PPPM costs were $13,933 (95% CI, $11,760-$16,105) higher in the IO+CT vs IO cohort (P < .001) and IO costs were $1024 (95% CI, $67-$1980) lower than CT (P = .04). CONCLUSIONS: IO+CT accounts for almost one-third of 1L aNSCLC treatment modalities, coinciding with a reduction in treatment with CT. Costs for patients treated with IO were lower than those for patients treated with both IO+CT and CT alone, driven primarily by antineoplastic drug and associated medical costs.

RESUMO

AIM: This economic analysis evaluated the cost-effectiveness of nivolumab (NIVO) plus ipilimumab (IPI) plus two cycles of platinum-doublet chemotherapy (PDC) compared with four cycles of PDC as first-line treatment for patients with advanced NSCLC in the United States (US). METHODS: A partitioned survival model was constructed with three mutually exclusive health states: progression free, progressed disease, and death. The analysis was conducted from a US healthcare payer perspective, using a time horizon of 25 years. Costs and outcomes were discounted at 3% annually. Survival outcomes from CheckMate 9LA were extrapolated with longer follow-up data from CheckMate 227 Part 1 (NIVO + IPI) and validated against data from other relevant clinical trials and real-world registries. Health-related quality of life utility values were derived from EQ-5D-3L data collected in CheckMate 9LA. US-specific costs (2020 dollars) were used for disease management; drug acquisition, administration, and monitoring; end-of-life care; adverse events; and subsequent treatments. Model outcomes included life years (LYs) gained, quality-adjusted LYs (QALYs) gained, and incremental cost-effectiveness ratio (ICER) for NIVO + IPI + PDC versus PDC. Sensitivity and scenario analyses were conducted. RESULTS: NIVO + IPI + PDC was associated with higher projected health benefits than PDC, including gains in LYs (3.71 vs 1.89) and QALYs (2.86 vs 1.37), and higher costs ($317,581 vs $119,909). The ICER was $132,960/QALY gained. NIVO + IPI + PDC had a 78-100% probability of being cost-effective at a willingness-to-pay threshold of $150,000-$250,000/QALY. Sensitivity and scenario analyses indicated that the results were robust to changes in key parameters. LIMITATIONS: The inherent limitation in extrapolating clinical trial data was mitigated using data from the more mature CheckMate 227 Part 1 trial and validating the outcomes against data from other relevant trials and real-world registries. CONCLUSION: NIVO + IPI + PDC (two cycles) provides a new first-line treatment option for patients with advanced NSCLC that is cost-effective within a range considered acceptable in the US.

RESUMO

AIM: We evaluated the cost-effectiveness of nivolumab in combination with ipilimumab (NIVO + IPI) versus platinum-doublet chemotherapy (PDC) for the first-line treatment of stage IV or recurrent non-small cell lung cancer (NSCLC) from a third-party payer perspective in the United States (US). METHODS: A partitioned survival model was developed using efficacy, safety, and utility inputs derived from Part 1 of the phase 3 CheckMate 227 trial (NCT02477826) with 37.7-month minimum follow-up for overall survival (OS). OS and progression-free (PF) survival were extrapolated over a 20-year time-horizon using parametric spline-based models selected based on goodness of fit and validated with data from external sources. Duration of treatment Kaplan-Meier curves were used for treatment cost calculations. US-specific costs (2021 dollars) for drug acquisition, administration, and monitoring; disease management (PF and progressed disease health states); end-of-life care; adverse events; and subsequent treatments were derived from publicly available sources. Time-to-death utilities were applied in the base case, whereas treatment-specific progression-based utilities were tested in a scenario analysis. Main outcomes included incremental cost per life-year gained (LYG) and quality-adjusted life-year (QALY). Model uncertainty was assessed through deterministic and probabilistic sensitivity analyses. RESULTS: NIVO + IPI resulted in 1.53 additional life-years, 1.33 additional QALYs, and $142 088 in additional costs compared with PDC. The incremental cost per LYG was $92 651, whereas incremental cost per QALY gained was $106 553. The application of treatment-specific progression-based utilities yielded an incremental cost per QALY gained of $117 076. Probabilistic sensitivity analysis revealed a 98% probability that NIVO + IPI was cost-effective versus PDC at a willingness-to-pay threshold of $150 000 per QALY. CONCLUSIONS: NIVO + IPI was estimated to be cost-effective as a first-line treatment for stage IV or recurrent NSCLC in the US, with increased survival and higher cost compared with PDC.

RESUMO

BACKGROUND: Tumor mutational burden (TMB) is a potential biomarker to predict tumor response to immuno-oncology agents in patients with metastatic non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: A multi-site cohort study evaluated patients diagnosed with stage IV NSCLC between 2012 and 2019 who had received comprehensive genomic profiling (CGP) and any NSCLC-related treatment at 9 U.S. cancer centers. Baseline characteristics and clinical outcomes were compared between patients with TMB <10 and TMB ≥10. RESULTS: Among the 667 patients with CGP results, most patients received CGP from Foundation Medicine (64%) or Caris (20%). Patients with TMB ≥10 (vs. TMB <10) were associated with a positive smoking history. TMB was associated with ALK (p = 0.01), EGFR (p < 0.01), and TP53 (p < 0.05) alterations. TMB >10 showed a significant association towards longer overall survival (OS) (HR: 0.43, 95% CI: 0.21-0.88, p = 0.02) and progression-free survival (PFS) (HR: 0.43, 95% CI: 0.21-0.85, p = 0.02) in patients treated with first-line immunotherapy and tested by Foundation Medicine or Caris at treatment initiation. CONCLUSIONS: TMB levels greater than or equal to 10 mut/Mb, when tested by Foundation Medicine or Caris at treatment initiation, were significantly associated with improved OS and PFS among patients treated with first-line immunotherapy-containing regimens. Additional prospective research is warranted to validate this biomarker along with PD-L1 expression.

RESUMO

OBJECTIVES: To know the clinical presentation and outcome of children with pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV- 2 (PIMS-TS) at a pediatric tertiary care center in Chennai. METHODS: Clinical and biochemical parameters of 65 children with PIMS-TS treated between July and October 2020 were studied. All children had their COVID RT-PCR and IgG COVID antibodies tests done. RESULTS: Mean age of the study group was 5.65 ± 3.68 y. Fever with red eyes, rash, vomiting, abdominal pain, and shock were common presenting features. Sixty percent of the study group had Kawasaki/incomplete Kawasaki features. Sixty-seven percent of the study group had coronary dilatation, 41% presented with shock, and 25% had left ventricular dysfunction. Coronary aneurysms were documented in 58% of the study group (z score more than 2.5). Respiratory presentation with pneumonia was seen in 10%. Four children presented with acute abdomen. Acute kidney injury, acute liver failure, hemolysis, pancytopenia, macrophage activation syndrome, encephalopathy, and multiorgan dysfunction syndrome (MODS) were other features. Forty-three percent required noninvasive oxygen support and 15.4% required mechanical ventilation. Intravenous immunoglobulin (73.8%) and methylprednisolone (49.8%) were used for therapy. Mortality in the study was 6%, which was due to MODS. CONCLUSIONS: Acute febrile illness with mucocutaneous and gastrointestinal manifestations should have PIMS-TS as a possible differential diagnosis and needs evaluation with inflammatory markers and SARS-CoV-2 antibodies.

RESUMO

Background: This study explored how low-income women already distressed by reproductive challenges were affected during the initial lockdown conditions of the COVID-19 pandemic in Mumbai, India. Methods: Women with reproductive challenges and living in established slums participated in a longitudinal mixed-methods study comparing their mental health over time, at pre-COVID-19 and at one and four-months into India's COVID-19 lockdown. Results: Participants (n = 98) who presented with elevated mental health symptoms at baseline had significantly reduced symptoms during the initial lockdown. Improvements were associated with income, socioeconomic status, perceived stress, social support, coping strategies, and life satisfaction. Life satisfaction explained 37% of the variance in mental health change, which was qualitatively linked with greater family time (social support) and less worry about necessities, which were subsidized by the government. Conclusions: As the pandemic continues and government support wanes, original mental health issues are likely to resurface and possibly worsen, if unaddressed. Our research points to the health benefits experienced by the poor in India when basic needs are at least partially met with government assistance. Moreover, our findings point to the critical role of social support for women suffering reproductive challenges, who often grieve alone. Future interventions to serve these women should take this into account.

RESUMO

Vagus nerve stimulation (VNS) paired with rehabilitation training is emerging as a potential treatment for improving recovery of motor function following stroke. In rats, VNS paired with skilled forelimb training results in significant reorganization of the somatotopic cortical motor map; however, the mechanisms underlying this form of VNS-dependent plasticity remain unclear. Recent studies have shown that VNS-driven cortical plasticity is dependent on noradrenergic innervation of the neocortex. In the central nervous system, noradrenergic α2 receptors (α2-ARs) are widely expressed in the motor cortex and have been critically implicated in synaptic communication and plasticity. In current study, we examined whether activation of cortical α2-ARs is necessary for VNS-driven motor cortical reorganization to occur. Consistent with previous studies, we found that VNS paired with motor training enlarges the map representation of task-relevant musculature in the motor cortex. Infusion of α2-AR antagonists into M1 blocked VNS-driven motor map reorganization from occurring. Our results suggest that local α2-AR activation is required for VNS-induced cortical reorganization to occur, providing insight into the mechanisms that may underlie the neuroplastic effects of VNS therapy.

RESUMO

OBJECTIVES: To determine the lifetime cost-effectiveness of nivolumab vs docetaxel in advanced squamous and nonsquamous non-small cell lung cancer (NSCLC) following platinum-based chemotherapy from a US payer perspective. STUDY DESIGN: Trial- and cohort-based cost-effectiveness analyses. METHODS: The analyses used partitioned survival models with 3 mutually exclusive health states: progression free, progressed disease, and death. The mean starting age was 61 years. Clinical parameters were derived from the 2 registrational, randomized, phase 3 trials with a minimum follow-up of 5 years. Costs were derived from published literature. The primary outcomes were quality-adjusted life-years (QALYs), life-years gained (LYG), and incremental cost-effectiveness ratios (ICERs). Costs and outcomes were discounted at 3% per annum. Uncertainty was examined using univariate and probabilistic sensitivity analyses. RESULTS: In patients with squamous NSCLC, the use of nivolumab improved life-years (LYs) and QALYs by 1.23 and 0.99, respectively, compared with docetaxel. Costs were increased by $99,677, resulting in ICERs of $100,776 per QALY and $81,294 per LYG. In patients with nonsquamous NSCLC, nivolumab increased LYs and QALYs by 0.99 and 0.80, respectively. Costs were increased by $94,174, resulting in ICERs of $117,739 per QALY and $94,849 per LYG. ICERs were most sensitive to the discount rates applied to costs and outcomes. At a willingness-to-pay threshold of $150,000, nivolumab had probabilities of 91% and 99% of being cost-effective in patients with squamous and nonsquamous NSCLC, respectively. CONCLUSIONS: Nivolumab is likely to be cost-effective for the treatment of patients with advanced NSCLC following platinum-based chemotherapy in the United States.

RESUMO

BACKGROUND: India has the highest number of stillbirths and the highest neonatal death rate in the world. In the context of its pronatalist society, women who experience perinatal loss often encounter significant social repercussions on top of grief. Furthermore, even when pregnancy outcomes were favorable, adverse life circumstances put some women at risk for postnatal depression. Therefore, perinatal loss and postnatal depression take a heavy toll on women's mental health. The purpose of this study is to assess mental health among a sample of Mumbai slum-dwelling women with a history of recent childbirth, stillbirth, or infant death, who are at risk for perinatal grief, postnatal depression, or mental health sequelae. METHODS: We conducted a mixed method, cross-sectional study. A focus group discussion informed the development of a comprehensive survey using mainly internationally validated scales. After rigorous forward and back-translation, surveys were administered as face-to-face structured interviews due to low literacy and research naiveté among our respondents. Interviews were conducted by culturally, linguistically, gender-matched, trained research assistants. RESULTS: Of our reproductive age (N = 260) participants, 105 had experienced stillbirth, 69 had a history of infant death, and 25 had experienced both types of loss. Nearly half of the sample met criteria for postnatal depression, and 20% of these women also met criteria for perinatal grief. Anxiety and depression varied by subgroup, and was highest among women desiring an intervention. CONCLUSIONS: Understanding factors contributing to women's suffering related to reproductive challenges in this pronatalist context is critically important for women's wellbeing.

RESUMO

PURPOSE: Given the pressures surrounding women's reproductive role in India, and persistent high rates of perinatal death, the purpose of this study is to describe and compare poor rural and urban Indian women's experiences of perinatal grief. PARTICIPANTS AND METHODS: Two cross-sectional studies were compared on shared quantitative variables. Poor rural (N = 217) and urban, slum-dwelling (N = 149) Central Indian women with a history of stillbirth, and/or infant death were recruited with the aid of local community health workers. Trained, local, gender, and linguistically matched research assistants conducted the structured interviews. Shared quantitative variables include demographics, Social Provision Scale, Shortened Ways of Coping-Revised, Perinatal Grief Scale, social norms and autonomy. RESULTS: While similar with respect to SES, age, number of living sons and perinatal loss experiences, these samples of poor women differed significantly across many variables, most notably women's household position, joint family living, number of live daughters, religious coping, autonomy, and degrees of perinatal grief. While perinatal grief was significantly associated with many variables bi-variably, most lost their relative influence in our stepwise multivariable modeling within site (rural/urban), with only social norms and social support remaining significant for rural (31% of variance) and wishful thinking and social norms for urban participants (38.4% of variance). In the combined sample household position, social support and social norms remained significant and explained 53.6% of the adjusted variance. CONCLUSION: In both samples, perinatal grief was high following perinatal loss. Both groups of women with perinatal loss have increased risk of mental health sequelae. Notably, the context affected how they experienced perinatal grief, with rural women's grief being higher and more affected by their societal pressures and isolation. Such nuances are important considerations for much-needed tailored approaches to future interventions.

RESUMO

BACKGROUND: In phase 3 clinical trials, nivolumab prolonged overall survival (OS) compared to chemotherapy in patients with previously treated advanced non-small-cell lung cancer (NSCLC). This retrospective real-world study evaluated OS in patients receiving nivolumab for previously treated advanced NSCLC primarily in US community hospitals. PATIENTS AND METHODS: Patient data were taken from electronic health records in the Flatiron Health oncology database. OS was evaluated in patients receiving nivolumab monotherapy for nonsquamous or squamous advanced NSCLC after prior chemotherapy; subgroup analyses were performed by Eastern Cooperative Oncology Group performance status (ECOG PS), age, and other baseline characteristics. Cox analysis was used to determine OS predictors. RESULTS: Of 3019 included patients, 1968 (65%) had nonsquamous and 1051 (35%) had squamous histology. In both cohorts, approximately 20% of patients had a verified ECOG PS ≥ 2, and > 25% were aged ≥ 75 years. For all patients, median OS in the nonsquamous and squamous cohorts was 8.6 months (95% confidence interval [CI], 8.0-9.3) and 7.4 months (95% CI, 6.8-8.5), respectively; for those with ECOG PS 0-1, median OS was 10.8 months (95% CI, 9.8-11.8) and 8.7 months (95% CI, 7.6-9.7), respectively. In both cohorts, programmed death ligand 1 expression ≥ 1% and ECOG PS 0-1 were associated with longer OS (P < .05); the number of prior lines of therapy and age ≥ 75 years had no significant association with OS. CONCLUSIONS: This study confirmed the effectiveness of nivolumab monotherapy for previously treated advanced NSCLC in real-world clinical practice. Poor ECOG PS, but not advanced age, was associated with shorter OS.

RESUMO

Axion dark matter experiment ultra-low noise haloscope technology has enabled the successful completion of two science runs (1A and 1B) that looked for dark matter axions in the 2.66-3.1 µeV mass range with Dine-Fischler-Srednicki-Zhitnisky sensitivity [Du et al., Phys. Rev. Lett. 120, 151301 (2018) and Braine et al., Phys. Rev. Lett. 124, 101303 (2020)]. Therefore, it is the most sensitive axion search experiment to date in this mass range. We discuss the technological advances made in the last several years to achieve this sensitivity, which includes the implementation of components, such as the state-of-the-art quantum-noise-limited amplifiers and a dilution refrigerator. Furthermore, we demonstrate the use of a frequency tunable microstrip superconducting quantum interference device amplifier in run 1A, and a Josephson parametric amplifier in run 1B, along with novel analysis tools that characterize the system noise temperature.
