Network meta-analysis of combination strategies in metastatic hormone-sensitive prostate cancer.

ABSTRACT: This study compared different doublet and triplet therapies for efficacy and safety in metastatic hormone-sensitive prostate cancer (mHSPC). PubMed, EMBASE, and the Cochrane Library were comprehensively searched for eligible randomized controlled trials (RCTs) published from inception to October 2023. Interventions included abiraterone, apalutamide, enzalutamide, docetaxel, darolutamide, and androgen deprivation therapy (ADT), either as doublet or triplet therapies. The outcomes examined were overall survival (OS), progression-free survival (PFS), castration-resistant prostate cancer (CRPC)-free survival, time to symptomatic skeletal event (SSE), and toxicity. The surface under the cumulative ranking curve (SUCRA) was determined to identify the preferred treatments. Ten RCTs were included. The combination of darolutamide, docetaxel, and ADT had the highest SUCRA of 84.3 for OS, followed by combined abiraterone, docetaxel, and ADT (SUCRA = 71.6). The highest SUCRAs for PFS were observed for triplet therapies (abiraterone, docetaxel, and ADT [SUCRA = 74.9], followed by enzalutamide, docetaxel, and ADT [SUCRA = 74.3]) and other androgen receptor axis-targeted therapy-based doublet therapies (SUCRAs: 26.5-59.3). Darolutamide, docetaxel, and ADT had the highest SUCRAs, i.e., 80.8 and 84.0 regarding CRPC-free survival and time to SSE, respectively. Regarding Grade >3 adverse events (AEs), the SUCRAs of triplet therapies (SUCRAs: 14.8-31.5) were similar to that of docetaxel and ADT (SUCRA = 39.5). Three studies had a low risk of bias in all categories; the remaining studies had at least an unclear risk of bias in at least one category. Triplet therapy demonstrated potentially enhanced effectiveness than doublet therapy in mHSPC, with acceptable safety concerns. Darolutamide might be the optimal option for triplet therapy in combination with docetaxel and ADT.

Prognostic value of primary tumor surgery in seminoma patients with distant metastasis at diagnosis: a population-based study.

The aims of this study were to determine the prognostic value of primary tumor surgery and identify optimal candidates for such surgery among patients with seminoma and distant metastasis at diagnosis. We identified 521 patients with seminoma and distant metastasis at diagnosis between 2004 and 2014 from the Surveillance, Epidemiology, and End Results database. Among these patients, 434 had undergone surgery, whereas 87 had not. The prognostic value of primary tumor surgery was assessed by Kaplan-Meier methods, log-rank analyses, and multivariate Cox's proportional hazards model. Survival curves and forest plots were also plotted. Survival analysis indicated that patients who underwent surgery had a better 5-year overall survival and cancer-specific survival than those who did not. Multivariate analyses demonstrated that primary tumor surgery is an independent prognostic factor for overall survival and cancer-specific survival, along with age at diagnosis, M stage, and marital status. In addition, primary tumor surgery still had considerable prognostic value in the subgroup of patients with lymph node metastasis. Further, forest plots demonstrated that patients with M1a stage, N1 or N2-3 stage, and a younger age at diagnosis (<60 years) may benefit from primary tumor surgery. In conclusion, our findings indicate that primary tumor surgery is correlated with improved survival in patients with seminoma and distant metastasis. Furthermore, primary tumor surgery is an independent prognostic indicator for patients with seminoma and distant metastasis.

Important Therapeutic Considerations in T1b Penile Cancer: Prognostic Significance and Adherence to Treatment Guidelines.

BACKGROUND: The clinical implications and contemporary management of T1b penile cancer are unknown. National treatment guidelines advocate surgical lymph node examination (SLNE) for T1b disease. OBJECTIVE: The aim of this study was to evaluate the prognosis of T1b disease and adherence to corresponding treatment guidelines. METHODS: We analyzed 296 patients from two academic centers, and 1263 patients from the Surveillance, Epidemiology, and End Results (SEER) registry (median follow-up 48.3 and 21 months, respectively). Multivariate Cox and Fine-Gray regressions were applied for penile cancer-specific survival (PCSS) analyses. RESULTS: In the academic center cohort, 28.3% of T1 patients had T1b disease, all of whom underwent SLNE. Nodal metastases were detected in 86.7% of T1b patients and 13.2% of T1a patients (p < 0.001). Using T1a as a reference, PCSS was significantly poorer in the T1b patients, with an adjusted hazard ratio (aHR) of 4.10 (p = 0.03). In the SEER cohort, 16.8% of T1 patients were classified as T1b. SLNE was performed in 21.7% of the T1b patients versus 38.2% of the T2 patients (p = 0.002). The probability of nodal metastases was 2.23-fold higher in T1b patients than in T1a patients (p < 0.001). In clinical N0M0 patients without SLNE, compared with T1a disease, T1b was associated with an aHR of 4.40 and a subdistribution HR of 4.53 for PCSS (both p = 0.003). CONCLUSIONS: T1b penile cancer is strongly associated with nodal metastases and adverse PCSS, and is poorly managed according to guidelines recommended in the nationwide registry.

Nebulized Corticosteroids in the Treatment of COPD Exacerbations: Systematic Review, Meta-Analysis, and Clinical Perspective.

BACKGROUND: COPD guidelines report that systemic corticosteroids are preferred over inhaled corticosteroids in the treatment of exacerbations, but the inhaled route is considered to be an option. OBJECTIVES: To conduct a systematic review and meta-analysis regarding the efficacy and safety of inhaled corticosteroids for COPD exacerbations. The second objective was to provide pharmacologic and clinical perspectives of inhaled corticosteroids for COPD exacerbations. METHODS: The primary outcome was a change in FEV1 baseline versus the last measured value. Secondary outcomes were a change in (PaO2 ) and (PaCO2 ) baselines versus the last measured values; FEV1, PaO2 , and PaCO2 at 24 or 72 h; and hyperglycemia. RESULTS: Each of the 9 studies included in the meta-analysis was conducted in subjects who were hospitalized and not critically ill. Our meta-analysis indicated that high-dose nebulized budesonide 4-8 mg/d was noninferior to systemic corticosteroids on the change in FEV1 between baseline and the last measured value (mean difference of 0.05, 95% CI -0.01 to 0.12, P = .13) and PaCO2 (mean difference of -1.14, 95% CI -2.56 to 0.27, P = .11) but of inferior efficacy for PaO2 changes (mean difference of -1.46, 95% -2.75 to -0.16, P = .03). Hyperglycemia was less frequent with high-dose nebulized budesonide (risk ratio, 0.13; 95% CI 0.03-0.46; P = .002). CONCLUSIONS: Based on our meta-analysis with a change in FEV1 as the primary end point, high-dose nebulized budesonide was an acceptable alternative to systemic corticosteroids in hospitalized subjects with COPD exacerbations who were not critically ill. Additional well-designed prospective studies are needed in both the acute care and ambulatory settings. We provide perspective on how this evidence might be applied in clinical practice.

Cardiovascular benefits of short-term indoor air filtration intervention in elderly living in Beijing: An extended analysis of BIAPSY study.

BACKGROUND: Adverse cardiovascular effects associated with air pollution exposure have been widely demonstrated. However, inconsistent cardiovascular responses were observed from reducing indoor air pollution exposure. We aimed to assess whether short-term air filtration intervention could benefit cardiovascular health in elderly living in high pollution area. METHODS: A randomized crossover intervention study of short-term indoor air filtration intervention on cardiovascular health was conducted among 35 non-smoking elderly participants living in Beijing in the winter of 2013, as part of Beijing Indoor Air Purifier StudY (BIAPSY). Portable air filtration units were randomly allocated to active filtration for 2 weeks and sham filtration for 2 weeks in the households. Twelve-hour daytime ambulatory heart rate variability (HRV) and blood pressure (ABP) were measured during active and sham filtration. Concurrently, real-time indoor and outdoor particulate matter with diameter less than 2.5 µm (PM2.5) and indoor black carbon (BC) concentrations were measured. We applied generalized additive mixed models to evaluate the associations of 1- to 10-h moving average (MA) exposures of indoor PM2.5 and BC with HRV and ABP indices, and to explore whether these associations could be modified by air filtration. RESULTS: We observed decreases of 34.8% in indoor PM2.5 and 35.3% in indoor BC concentrations during active filtration. Indoor PM2.5 and BC exposures were significantly associated with reduced HRV and increased ABP indices, and greater changes were observed during sham filtration. In specific, each 10 µg/m3 increase in indoor PM2.5 at MA8-h was associated with a significant reduction of 1.34% (95% CI: -2.42, -0.26) in SDNN during sham filtration, compared with a non-significant reduction of 0.81% (95% CI: -6.00, 4.68) during active filtration (Pinter< 0.001). Each 1 µg/m3 increase in indoor BC at MA8-h was associated with a significant increase of 2.41% (95% CI: 0.38, 4.47) in SBP during sham filtration, compared with a non-significant increase of -1.09% (95% CI: -4.06, 1.96) during active filtration (Pinter = 0.135). Nonlinear inverse exposure-response relationships of indoor air pollution exposures with predicted HRV and ABP indices also confirmed some cardiovascular benefits of short-term air filtration intervention. CONCLUSIONS: Our results suggested that short-term indoor air filtration intervention can be of some cardiovascular benefits in elderly living with high pollution episodes.

General and Specific Genetic Polymorphism of Cytokines-Related Gene in AITD.

Autoimmune thyroid disease (AITD) shows the highest incidence among organ-specific autoimmune diseases and is the most common thyroid disease in humans, including Graves' disease (GD) and Hashimoto's thyroiditis (HT). The susceptibility to autoimmune diseases is affected by increased autoantibody levels, susceptibility gene polymorphisms, environmental factors, and psychological factors, but the pathogenesis remains unclear. Various cytokines and related genes encoding them play important roles in the development and progression of AITD. CD152, an expression product of the CTLA-4 gene, downregulates T cell activation. The A/A genotype polymorphism in the CT60 locus may reduce the production of thyroid autoantibodies. The C1858T polymorphism of the PTNP22 gene reduces the expression of its encoded LYP, which increases the risk of GD and HT. GD is an organ-specific autoimmune disease involving increased secretion of thyroid hormone, whereas HT may be associated with the destruction of thyroid gland tissue and hypothyroidism. These two diseases exhibit similar pathogenesis but opposite trends in the clinical manifestations. In this review, we focus on the structure and function of these cytokines and related genes in AITD, as well as the association of polymorphisms with susceptibility to GD and HT, and attempt to describe their differences in pathogenesis and clinical manifestations.

Systemic Inflammatory Marker CRP Was Better Predictor of Readmission for AECOPD Than Sputum Inflammatory Markers.

INTRODUCTION: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) readmission contributes considerably to the worse outcomes for COPD patients. Predictors for readmission include some socio-demographic variables and the severity of the underlying disease, however, few evidence suggested whether persistently heightened airway or systemic inflammation was related to recurrence of AECOPD. The aim of this study was to evaluate role of airway and systemic inflammatory biomarkers during AECOPD on predicting readmission for AECOPD. METHODS: Consecutive hospitalized patients with AECOPD were recruited. Inflammatory and clinical indices were evaluated at the day of admission before starting therapy and the day of planned discharge (day 10-14). Predictors for readmission were assessed by binary logistic regression model. RESULTS: 93 patients were included with 51 patients (54.8%) were readmitted due to AECOPD at least once during 1 year following the index admission. The logistic regression model indicated that age (OR=1.072, 95%CI: 1.012-1.135, P=.017), hs-CRP (high sensitive-C reactive protein) at day 14 (OR=1.392, 95%CI: 1.131-1.712, P=.002), CAT value at day 14 (OR=1.12, 95%CI: 1.031-1.217, P=.007) were the independent variables statistically significant in predicting rehospitalization. CONCLUSION: Systemic inflammatory marker CRP was a better predictor of readmission than sputum inflammatory markers. CAT score and age were also useful to predict readmission.

Pulmonary Extranodal Natural Killer/T-Cell Lymphoma (Nasal Type): A Case Report and Radiological Image Review.

An 83-year-old woman presented with intermittent fever for 2 weeks. Chest radiography and computed tomography images showed multiple nodules and masses scattered in both lung fields. Tissue samples obtained by computed tomography-guided needle biopsy revealed extranodal natural killer/T-cell lymphoma (ENKL). The lung is the major site of involvement and the skin may be the primary site. The radiological imaging of this case is different from the cases reported before. Besides, we reviewed the medical records of our hospital and searched the Pubmed database and found 12 cases altogether (include the case presented), which were diagnosed with pulmonary ENKL, and the features of chest images were studied. To our knowledge, this is the first time that the chest imaging features of pulmonary ENKL were reviewed. We conclude that if the radiographic manifestations are multiple patchy consolidations or multiple nodules and masses in both lungs with or without bilateral pleural effusions, the diagnostic considerations should include ENKL.

High-accuracy stereo matching based on adaptive ground control points.

This paper proposes a novel high-accuracy stereo matching scheme based on adaptive ground control points (AdaptGCP). Different from traditional fixed GCP-based methods, we consider color dissimilarity, spatial relation, and the pixel-matching reliability to select GCP adaptively in each local support window. To minimize the global energy, we propose a practical solution, named as alternating updating scheme of disparity and confidence map, which can effectively eliminate the redundant and interfering information of unreliable pixels. The disparity values of those unreliable pixels are reassigned with the information provided by local plane model, which is fitted with GCPs. Then, the confidence map is updated according to the disparity reassignment and the left-right consistency. Finally, the disparity map is refined by multistep filers. Quantitative evaluations demonstrate the effectiveness of our AdaptGCP scheme for regularizing the ill-posed matching problem. The top ranks on Middlebury benchmark with different error thresholds show that our algorithm achieves the state-of-the-art performance among the latest stereo matching algorithms. This paper provides a new insight toward high-accuracy stereo matching.

Lung function and cytokine levels in professional athletes.

OBJECTIVE: Previous studies have demonstrated that exercise-induced asthma and bronchial hyperresponsiveness commonly occur in athletes. The present study investigates pulmonary function and cytokine levels in professional athletes to explore the impact of various sports on respiratory system function and to evaluate the possible role of systemic anaphylaxis. METHODS: Lung function was measured at rest in professional athletes without a history of smoking. Athletes were recruited from 10 different sports including swimming, water ballet, shooting, volleyball, softball, football, kickboxing, fencing, judo, and track and field. Measurements included forced vital capacity (FVC), forced expiratory volume in one second (FEV(1)), vital capacity (VC), peak expiratory flow (PEF), maximal mid-expiratory flow curve (MMEF), and forced expiratory flow rate (FEF(25-75)%). In addition, the medical history of all athletes was recorded. Correlations between lung function measurements and the different sports, age, gender, height and weight were analyzed. In some athletes, serum was sampled to detect IL-4 and IL-10 concentrations. In these subjects, the correlation between pulmonary function and cytokine levels was analyzed. RESULTS: A total of 147 professional athletes and 30 healthy volunteers were enrolled in the study. Allergic rhinitis and asthma were detected only in swimmers with an incidence of 56.52% (13/23) and 8.70% (2/23), respectively. Lung function measures were significantly correlated with sport, age, gender, height, and weight. Ventilation functions (including FVC, FEV(1), FEV(1)/FVC, and MMV) in male athletes were superior to those in females, and the ventilation functions in swimmers were superior to those in others. However, the small airway functions (MMEF, FEF(50), FEF(75)) in swimmers and in track and field athletes were lower than predicted (swimmers: 72%, 70%, and 78%, respectively; track and field athletes: 79%, 75%, and 99%, respectively). Serum analyses for IL-4 and IL-10 revealed that IL-4 concentrations were higher in swimmers 69.34 +/- 22.4 pg/mL relative to non-swimmers (p = 0.000). By contrast IL-10 concentrations were lower in swimmers 34.94 +/- 9.71 pg/mL than that in the static group (44.69 +/- 16.32 pg/mL; p = 0.027). IL-4 levels were negatively correlated with FEV(1)%, FEF(25)%, FEF(50)%, and MMEF%. By contrast, IL-10 levels were not correlated with any of these measures. CONCLUSIONS: The lung function measurements were correlated with sport, age, gender, height, and weight in the various athletes. The lung capacity of swimmers was greater than that of other athletes. Small airway dysfunction was observed in some swimmers and endurance athletes. We observed an association between systemic anaphylaxis and small airway dysfunction after prolonged regular training, particularly following swimming and endurance training.
