Assessing intrinsic capacity in Taiwan: Initial psychometric properties of the Integrated Care for Older People Screening Tool for Taiwanese (ICOPES-TW).

BACKGROUND: The World Health Organization (WHO) proposed the concept of intrinsic capacity (comprising composite physical and mental capacity) which aligns with their concepts of healthy aging and functional ability. Consequently, the WHO promotes the Integrated Care for Older People (ICOPE) framework as guidance for geriatric care. Consequently, each government should have a screening tool corresponding to ICOPE framework to promote geriatric care. The present study examined the initial psychometric properties of the Taiwan version of ICOPE (i.e., ICOPES-TW). METHODS: Older people (n = 1235; mean age = 72.63 years; 634 females [51.3%]) were approached by well-trained interviewers for participation. A number of measures were administered including the ICOPES-TW, WHOQOL-AGE (assessing quality of life [QoL]), Clinical Frailty Scale (assessing frailty), Barthel Index (assessing basic activity of daily living [BADL]), and Lawton Instrumental Activities of Daily Living Scale (assessing instrumental activity of daily living [IADL]). RESULTS: The ICOPES-TW had a two-factor structure (body functionality [eigenvalue = 1.932] and life adaptation [eigenvalue = 1.170]) as indicated by the results of exploratory factor analysis. Internal consistency of the ICOPES-TW was low (Cronbach's α = 0.55 [entire ICOPES-TW], 0.45 (body functionality factor), and 0.52 (life adaptation factor). ICOPES-TW scores were significantly (i) positively correlated with age (r = 0.321), IADL (r = 0.313), and frailty (r = 0.601), and (ii) negatively correlated with QoL (r=-0.447), and BADL (r=-0.447), with all p-values < 0.001. CONCLUSION: The ICOPES-TW could be a useful screening tool for healthcare providers to quickly evaluate intrinsic capacity for Taiwanese older people given that it has moderate to strong associations with age, BADL, IADL, QoL, and frailty.

Herpes zoster associated with stroke incidence in people living with human immunodeficiency virus: a nested case-control study.

BACKGROUND: The incidence of stroke is increasing among younger people with human immunodeficiency virus (HIV). The burden of stroke has shifted toward the young people living with HIV, particularly in low- and middle-income countries. People infected with herpes zoster (HZ) were more likely to suffer stroke than the general population. However, the association of HZ infection with the incidence of stroke among patients with HIV remains unclear. METHODS: A nested case-control study was conducted with patients with HIV registered in the Taiwan National Health Insurance Research Database in 2000-2017. A total of 509 stroke cases were 1:10 matched to 5090 non-stroke controls on age, sex, and date of first stroke diagnosis. Logistic regression models were used to estimate the odds ratio and 95% confidence intervals (CI) of stroke incidence. RESULTS: The odds ratio of stroke was significantly higher in the HIV-infected population with HZ (adjusted odds ratio [AOR]: 1.85, 95% CI: 1.42-2.41). A significantly increased AOR of stroke was associated with hypertension (AOR: 3.53, 95% CI: 2.86-4.34), heart disease (AOR: 2.32, 95% CI: 1.54-3.48), chronic kidney disease (AOR: 1.82, 95% CI: 1.16-2.85), hepatitis C virus infection (AOR: 1.49, 95% CI: 1.22-1.83), hyperlipidemia (OR: 1.41, 95% CI: 1.12-1.78), and treatment with protease inhibitors (AOR: 1.33, 95% CI: 1.05-1.69). CONCLUSIONS: Our findings suggest that HZ concurrent with HIV may increase the risk of stroke. The incidence rates of stroke were independent of common risk factors, suggesting strategies for early prevention of HZ infection among people living with HIV.

Global overview of suicidal behavior and associated risk factors among people living with human immunodeficiency virus: A scoping review.

Death by suicide is a major public health problem. People living with human immunodeficiency virus (PLHIV) have higher risk of suicidal behavior than the general population. The aim of this review is to summarize suicidal behavior, associated risk factors, and risk populations among PLHIV. Research studies in six databases from January 1, 1988, to July 8, 2021, were searched using keywords that included "HIV," "suicide," and "risk factors." The study design, suicide measurement techniques, risk factors, and study findings were extracted. A total of 193 studies were included. We found that the Americas, Europe, and Asia have the highest rates of suicidal behavior. Suicide risk factors include demographic factors, mental illness, and physiological, psychological, and social support. Depression is the most common risk factor for PLHIV, with suicidal ideation and attempt risk. Drug overdosage is the main cause of suicide death. In conclusion, the current study found that PLHIV had experienced a high level of suicidal status. This review provides an overview of suicidal behavior and its risk factors in PLHIV with the goal of better managing these factors and thus preventing death due to suicide.

Stereotactic radiosurgery with whole brain radiotherapy combined with bevacizumab in the treatment of brain metastases from NSCLC.

OBJECTIVE: Non-small cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. Whole-brain radiotherapy (WBRT) is one of the standard treatment strategies for NSCLC. It is interesting to combine angiogenesis inhibitors such as bevacizumab with radiation therapy. This study aimed to explore the efficacy and safety of stereotactic radiosurgery (SRS) with WBRT combined with bevacizumab in the treatment of brain metastases. METHODS: A total of 21 patients with brain metastases from NSCLC were treated with bevacizumab and WBRT-SRS, while 28 patients were treated with WBRT-SRS only. The bevacizumab average dose was 5-7.5 mg/kg, approximately 2 cycles during radiotherapy. Tumor responses were evaluated every 3 months based on Response Evaluation Criteria in Solid Tumors version 1.1. RESULTS: The median follow-up time was 13.5 months (range 2.7-88.4 months). The ORR and DCR of patients who received WBRT-SRS with or without bevacizumab were similar (p = 0.458, p = 0.382). OS(42.63 years VS 25.23 years, p = 0.02)and LPFS (39.53 years VS 23 years, p = 0.047)were better in WBRT-SRS with bevacizumab groups. After radiotherapy and 3 months after radiotherapy, the volume of peritumoral edema was significantly reduced in WBRT-SRS with bevacizumab groups(45.62 ± 24.03 cm3 vs 63.03 ± 25.44 cm3, p = 0.036;8.63 ± 6.87 cm3 vs 15.62 ± 10.58 cm3, p = 0.021). The main adverse reactions were similar in the two groups except for Venous thrombosis with bevacizumab (0 patients vs 5 patients, p = 0.006). CONCLUSION: Bevacizumab with radiotherapy improved the overall efficacy and reduced the peritumoral edema of BM from NSCLC.

Dynamic changes in quality of life, psychological status, and body image in women who underwent a mastectomy as compared with breast reconstruction: an 8-year follow up.

BACKGROUND: Surgical decisions and methods of surgery highly influence long term QoL for breast cancer (BC) survivors. This study is aimed towards an exploration of the dynamic changes in quality of life (QoL), anxiety/depression status, and body image (BI) among women with BC who received a mastectomy compared with those receiving breast reconstruction (BR) within an 8-year follow-up period. METHODS: Women with major BC surgeries were invited to complete the World Health Organization Quality of Life-Brief (WHOQOL-BREF), the European quality of life five dimensions questionnaire (EQ-5D), and a body image scale within 8 years of surgery. Kernel smoothing methods were applied to describe dynamic changes in QoL, anxiety/depression, and BI at different time points. Linear mixed effects models were constructed to identify the interaction between time, different types of surgery, and the determinants of QoL in these patients. RESULTS: After 1:10 propensity score matching, a total of 741 women who had undergone a BR and mastectomy were included. The BR group exhibited a high WHOQOL QoL score one to five years after surgery with some fluctuations. The mastectomy group had comparatively stable QoL scores on WHOQOL items and were less depressed/anxious. The BR group generally showed fluctuating, higher BI scores two years after surgery, but they exhibited more anxiety/depression during follow up for 8 years. Medical comorbidities, the status of anxiety/depression, and BI were the major factors influencing all domains and items of the WHOQOL BREF among women with BC. CONCLUSION: The mastectomy group showed a decreased trend toward depression in patients with BC. The BR group showed a significant improvement in QoL in the first 5 years with massive fluctuations. These findings should be considered and discussed in patient participatory decision-making and promotion of QoL for breast cancer survivors.

The impact of driver mutation on the treatment outcome of early-stage lung cancer patients receiving neoadjuvant immunotherapy and chemotherapy.

Neoadjuvant immunotherapy and chemotherapy have improved the major pathological response (MPR) in patients with early-stage operable non-small cell lung cancer (NSCLC). This study aimed to assess whether the presence of targetable driver mutations affects the efficacy of the combination of immunotherapy and chemotherapy. We enrolled patients with early-stage operable NSCLC who received preoperative neoadjuvant therapy between January 1, 2017, and December 30, 2020. Neoadjuvant therapy was delivered with platinum-doublet chemotherapy; moreover, pembrolizumab was added at the attending physician's discretion based on patient's request. Pathological responses were assessed; moreover, disease-free survival was estimated. Next-generation sequencing was performed in case sufficient preoperative biopsy specimens were obtained. We included 23 patients; among them, 11 received a combination of neoadjuvant immunotherapy and chemotherapy while 12 received neoadjuvant chemotherapy alone. The MPR and pathological complete response rates were 54.5% and 27.3%, respectively, in patients who received a combination of neoadjuvant immunotherapy and chemotherapy. These rates were significantly higher than those in patients who only received neoadjuvant chemotherapy. Three patients in the combination group experienced disease recurrence during the follow-up period even though two of them showed an MPR. These three patients had targetable driver mutations, including an EGFR exon 20 insertion, EGFR exon 21 L858R substitution, and MET exon 14 skipping. Only one patient who remained disease-free had a targetable driver mutation. Among patients with early-stage operable NSCLC requiring neoadjuvant therapy, comprehensive genomic profiling is crucial before the administration of the combination of neoadjuvant immunotherapy and chemotherapy.

Survival benefit of osimertinib combination therapy in patients with T790M-positive non-small-cell lung cancer refractory to osimertinib treatment.

OBJECTIVES: Osimertinib is the main treatment choice for pretreated patients with advanced non-small cell lung cancer (NSCLC) harbouring epidermal growth factor receptor (EGFR) T790M mutations. However, the choice of subsequent therapy when progressive disease has developed after osimertinib treatment remains a major therapeutic challenge. This study evaluated the efficacy of osimertinib-based combination therapies in patients who developed progressive disease after treatment with osimertinib. MATERIAL AND METHODS: We enrolled NSCLC patients harbouring T790M mutations pretreated with first- or second-generation EGFR tyrosine-kinase inhibitors and were receiving osimertinib at two tertiary referral centres between August 2015 and July 2019, and the subsequent treatment efficacy was assessed. RESULTS: Osimertinib-based combination therapy yielded better overall survival (OS) than chemotherapy alone (not achieved vs. 7.8 months; hazard ratio, 0.39; 95 % confidence interval 0.17-0.89; P = 0.025) according to the Cox proportional hazards model adjusted for possible confounders. Synergism (combination index <1) between AZD9291 and chemotherapy and a higher proportion of apoptosis cells in combination treatment were also demonstrated in the T790M-positive PC9 cell line with acquired resistance to AZD9291. CONCLUSION: Our data supported the hypothesis that osimertinib-based combination therapy is associated with improved OS among patients with clinical progression following the use of osimertinib. These findings warrant further validation in a randomised controlled study.

Is nurse-led case management effective in improving treatment outcomes for cancer patients? A systematic review and meta-analysis.

AIMS: To identify and synthesize the outcomes of nurse-led case management interventions for improving cancer treatment. DESIGN: Systematic review with meta-analysis. DATA SOURCES: PubMed, MEDLINE, CINAHL, EMBASE, Cochrane Library and CEPS were searched for articles published from inception till June 2019, and search was finalized in January 2020. REVIEW METHODS: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The quality of evidence was assessed using Joanna Briggs Institute Critical Appraisal Tools. Outcomes were analysed by using a pool of data of 95% confidence intervals (CIs), p value and fitting model based on heterogeneity of test results. RESULTS: Eleven articles were included in the meta-analysis. When compared with the regular care group, the nurse-led case management group had: 1) shorter time from diagnosis to treatment by 9.07 days, 2) an improved treatment completion rates (OR = 2.45) and 3) more number of patients received hormone therapy. CONCLUSION: The synthesized results presented that nurse-led case management is more effective than regular care in improving treatment timeliness, treatment completion rates and hormone therapy rates.

Higher Risk of Depression After Total Mastectomy Versus Breast Reconstruction Among Adult Women With Breast Cancer: A Systematic Review and Metaregression.

This systematic review with a meta-regression was conducted to determine the risk of depression after mastectomy compared to breast reconstruction among women with breast cancer 1 year after surgery. A literature search was conducted according to PRISMA guidelines using 4 databases: Medline (Ovid), Embase, Cinahl, and the Cochrane Library for the period January 2000 to March 2019. Studies that measured the status of depression within 1 year and immediately after surgery were included. Outcomes related to depression were analyzed by using a pool of event rates and a risk ratio of 95% confidence interval (CI), P value, and a fitting model based on the results of a heterogeneity test of mastectomy and BR. The statistical analysis was conducted using Comprehensive Meta-analysis 3.0 software. Nine studies met the inclusion criteria. There were 865 cases of mastectomy only, with a 22.2% risk of depression (95% CI, 12.4-36.2). In 869 women who underwent BR, the risk of depression was 15.7% (95% CI, 8.8-26.2). The depression risk ratio for mastectomy compared to BR was 1.36 (95% CI, 1.11-1.65). Patients with delayed reconstruction exhibited lower levels of depression (risk ratio 0.96, 95% CI 0.57-1.01). The Beck Depression Inventory (BDI) scale showed high sensitivity, and the Hospital Anxiety Depression Scale (HADS) with a cutoff of > 7 could measure even low to moderate depressive symptoms. One in 4 women with breast cancer had symptoms of depression after mastectomy; both surgeries were associated with depression in women 1 year after surgery. Our results will permit the development of proactive treatment plans before and after surgery to mitigate risk and prevent depression through the use of sensitive depression scales like BDI.

Dietary Acid Load and the Risk of Pancreatic Cancer: A Prospective Cohort Study.

BACKGROUND: Modern Western diets are rich in acidogenic foods. Human and in vitro studies suggest a potential link between dietary acid load and cancer risk. However, no epidemiologic studies have investigated the association of dietary acid load with the risk of pancreatic cancer. Therefore, we conducted a prospective cohort study to fill this gap. METHODS: A population-based cohort of 95,708 American adults was identified. Potential renal acid load (PRAL) and net endogenous acid production (NEAP) were used to assess dietary acid load of each subject, with greater values indicating greater dietary acid load. Cox regression was used to estimate risk estimates for pancreatic cancer incidence. Predefined subgroup analysis was used to identify the potential effect modifiers. RESULTS: A total of 337 pancreatic cancer cases were observed during 848,534.0 person-years of follow-up. PRAL score was found to be positively associated with the risk of pancreatic cancer [fully adjusted HRquartile 4 vs. 1: 1.73; 95% confidence interval (95% CI), 1.21-2.48; P trend = 0.001] in a nonlinear dose-response pattern (P nonlinearity = 0.012). Subgroup analysis found that the positive association of PRAL score with the risk of pancreatic cancer was more pronounced in subjects aged <65 years than in those ≥65 years (P interaction = 0.018). Similar results were obtained for NEAP score. CONCLUSIONS: Higher dietary acid load is associated with a higher risk of pancreatic cancer. Future studies should validate our findings in other populations and settings. IMPACTS: This is the first epidemiologic study suggesting that reducing dietary acid load may be useful in primary prevention of pancreatic cancer.

Single vs Serial Measurements of Cardiac Troponin Level in the Evaluation of Patients in the Emergency Department With Suspected Acute Myocardial Infarction.

Importance: Chest pain is among the most common reasons for emergency department (ED) presentations. However, most patients are at low risk for acute coronary syndrome (ACS), with low cardiac adverse outcomes rates. Biomarker testing with troponin levels is key in the initial assessment for ACS. Although serial troponin testing can improve the diagnosis of ACS in clinical practice, some patients deemed to be low risk are discharged after a single negative troponin test result. Objective: To report the clinical outcomes of patients discharged after a single negative troponin test result compared with patients discharged after serial troponin measurements. Design, Setting, and Participants: This is a retrospective cohort study of ED encounters from May 5, 2016, to December 1, 2017, across 15 community EDs within an integrated health care system in southern California. The study cohort includes 27 918 adult ED encounters in which patients were evaluated for suspected ACS with a HEART (history, electrocardiogram, age, risk factors, and troponin) score and an initial conventional troponin-I measurement below the level of detection (<0.02 ng/mL). Statistical analysis was performed from December 1, 2019, to December 1, 2020. Exposure: Single troponin test vs multiple troponin tests. Main Outcomes and Measures: The primary outcome was acute myocardial infarction or cardiac mortality; secondary outcomes included coronary artery bypass graft, percutaneous coronary intervention, invasive coronary angiography, and unstable angina within 30 days of discharge. A multivariable logistic regression model was performed to evaluate the association between testing strategies and clinical outcomes. Results: A total of 27 918 patient encounters (16 212 women [58.1%]; mean [SD] age, 58.7 [15.2] years) were included in the study. Of patients with an initial troponin measurement below the level of detection, 14 459 (51.8%) were discharged after a single troponin measurement, and 13 459 (48.2%) underwent serial troponin tests. After adjustment for cardiac risk factors and comorbidities, there was no statistically significant difference in the primary outcome of acute myocardial infarction or cardiac mortality within 30 days between the 2 groups (single troponin, 56 [0.4%] vs serial troponin, 52 [0.4%]; adjusted odds ratio, 1.41 [95% CI, 0.96-2.07]). Patients discharged after a single troponin test had lower rates of coronary artery bypass graft (adjusted odds ratio, 0.24 [95% CI, 0.11-0.48]) and invasive coronary angiography (adjusted odds ratio, 0.46 [95% CI, 0.38-0.56]). Conclusions and Relevance: This study suggests that patients are routinely discharged from the ED after a single negative troponin test result, and when compared with serial troponin testing, a single troponin test appears safe based on current physician decision-making, with no difference in rates of 30-day cardiac mortality and acute myocardial infarction, which are low in both groups.

First-line treatment with irreversible tyrosine kinase inhibitors associated with longer OS in EGFR mutation-positive non-small cell lung cancer.

BACKGROUND: Few studies have compared the efficacy of the irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), afatinib, with that of reversible EGFR-TKIs. Therefore, this study assessed the effectiveness of afatinib, erlotinib, and gefitinib in terms of OS (overall survival) and progression-free survival (PFS) in EGFR mutation-positive advanced non-small cell lung cancer (NSCLC) patients. METHODS: Patients with EGFR mutation-positive advanced NSCLC who sought treatment from December 2013 to June 2018, at a tertiary referral center were retrospectively analyzed. These patients were treated with afatinib or a reversible EGFR-TKI (erlotinib or gefitinib) until disease progression, intolerable adverse events, or death. The Kaplan-Meier and log-rank tests were then used to compare the OS and PFS of the patients. We further analyzed the survival differences among the subgroup of patients without brain metastases. RESULTS: Of the 363 patients enrolled, 134 and 229 received first-line afatinib and first-line reversible EGFR-TKI, respectively. Those given afatinib had better OS (39.3 vs. 26.0 months; HR 0.65, P = 0.033) and PFS (14.1 vs.11.2 months; HR 0.58, P < 0.001). Of the 246 patients without brain metastases, 93 and 153 received first-line afatinib and a first-line reversible EGFR-TKI, respectively. Those given afatinib had a better OS (52.6 vs. 24.9 months; HR 0.62, P = 0.0030) and PFS (17.7 vs. 11.1 months; HR 0.51, P < 0.001). The survival benefit was more significant in the subgroup of patients with L858R substitutions. CONCLUSIONS: The results indicated that afatnib resulted in significantly better OS and PFS than gefitnib and erlotinib for EGFR mutation-positive advanced NSCLC patients without brain metastases. KEY POINTS: Significant findings of the study Afatnib resulted in significantly better overall survival and progression-free survival than gefitnib and erlotinib for EGFR mutation-positive advanced non-small cell lung cancer patients without brain metastases. What this study adds This study helps fill the gap in our limited understanding of the differences in the efficacy of the irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), afatinib, with that of reversible EGFR-TKIs.

Long noncoding RNA ZNF800 suppresses proliferation and migration of vascular smooth muscle cells by upregulating PTEN and inhibiting AKT/mTOR/HIF-1α signaling.

BACKGROUND AND AIMS: Long noncoding RNAs (lncRNAs) have recently been implicated in many biological and disease processes, but the exact mechanism of their involvement in atherosclerosis is unclear. The aberrant proliferation and migration of vascular smooth muscle cells (VSMCs) is a major contributor to the development of atherosclerotic lesions. This study aimed to investigate the potential effects of lncRNA ZNF800, a previously uncharacterized lncRNA, on VSMC proliferation and migration. METHODS: The expression of lncRNA ZNF800 in atherosclerotic plaque tissues was detected using reverse transcription-quantitative PCR (RT-qPCR), while the role and mechanism of lncRNA ZNF800 in proliferation and migration of VSMCs were investigated by CCK8 assay, transwell assay, scratch wound assay, RT-qPCR and Western blot. RESULTS: We found that lncRNA ZNF800 was significantly more abundant in atherosclerotic plaque tissues, and substantially suppressed the proliferation and migration of VSMCs. LncRNA ZNF800 had no effect on phosphatase and tensin homolog deleted on chromosome 10 (PTEN) mRNA expression but dramatically increased the levels of PTEN protein. Enhanced lncRNA ZNF800 expression inhibited the activity of the AKT/mTOR/HIF-1α signaling pathway, downregulated the expression of vascular endothelial growth factor α (VEGF-α) and matrix metalloproteinase 1 (MMP1), and suppressed VSMC proliferation and migration. These inhibitory effects of lncRNA ZNF800 were abolished by knockdown of PTEN. The inhibitory effects of lncRNA ZNF800 on cell proliferation and migration and the expression of VEGF-α and MMP1 were exacerbated by HIF-1α knockdown in VSMCs. CONCLUSIONS: These findings demonstrated that lncRNA ZNF800 suppressed VSMC proliferation and migration by interacting with PTEN through a mechanism involving AKT/mTOR/HIF-1α signaling. Therefore, it may play a key atheroprotective role and represent a potential therapeutic target for atherosclerosis-related diseases.

Total Antioxidant Capacity and Pancreatic Cancer Incidence and Mortality in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

BACKGROUND: Total antioxidant capacity (TAC) reflects an individual's overall antioxidant intake. We sought to clarify whether higher TAC is associated with lower risks of pancreatic cancer incidence and mortality in the U.S. general population. METHODS: A total of 96,018 American adults were identified from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. A ferric-reducing ability of plasma score was used to reflect an individual's TAC intake from diet and/or supplements. Cox regression was used to calculate hazard ratios (HR) for pancreatic cancer incidence, and competing risk regression was used to calculate subdistribution HRs for pancreatic cancer mortality. Restricted cubic spline regression was used to test nonlinearity. RESULTS: A total of 393 pancreatic cancer cases and 353 pancreatic cancer-related deaths were documented. Total (diet + supplements) TAC was found to be inversely associated with pancreatic cancer incidence (HR quartile 4 vs. quartile 1 = 0.53; 95% confidence interval, 0.39-0.72; P trend = 0.0002) and mortality (subdistribution HR quartile 4 vs. quartile 1 = 0.52; 95% confidence interval 0.38-0.72; P trend = 0.0003) in a nonlinear dose-response manner (all P nonlinearity < 0.01). Similar results were observed for dietary TAC. No association of supplemental TAC with pancreatic cancer incidence and mortality was found. CONCLUSIONS: In the U.S. general population, dietary but not supplemental TAC level is inversely associated with risks of pancreatic cancer incidence and mortality in a nonlinear dose-response pattern. IMPACT: This is the first prospective study indicating that a diet rich in antioxidants may be beneficial in decreasing pancreatic cancer incidence and mortality.

ABO blood group and risk of newly diagnosed nonalcoholic fatty liver disease: A case-control study in Han Chinese population.

BACKGROUND: ABO blood group has been associated with cardiovascular disease and cancer. However, whether ABO blood group is associated with nonalcoholic fatty liver disease (NAFLD) remains unknown. The present study aimed to clarify this issue. METHODS: A hospital-based case-control study was performed in southwestern China. A total of 583 newly ultrasound-diagnosed NAFLD cases and 2068 controls were included. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of developing NAFLD were calculated by multivariate logistic regression. A propensity score was developed for adjustment and matching. RESULTS: The proportions of blood groups A, B, AB and O were 31%, 26%, 8% and 35%, respectively. Non-O blood groups were found to be significantly associated with an increased risk of NAFLD (the fully adjusted OR = 1.51, 95% CI: 1.19, 1.91); moreover, compared with blood group O, the fully adjusted ORs of developing NAFLD were 1.50 (95% CI: 1.13, 1.99) for blood group A, 1.59 (95% CI: 1.19, 2.14) for blood group B, and 1.37 (95% CI: 0.86, 2.18) for blood group AB. Similar results were obtained in both propensity-score-adjusted and propensity-score-matched analyses. No evidence of significant effect modification for the association of ABO blood group with the risk of NAFLD was found (all Pinteraction>0.05). CONCLUSIONS: Non-O blood groups are significantly associated with an increased risk of NAFLD. Our findings provide some epidemiological evidence for a possible role of ABO glycosyltransferase in the pathogenesis of NAFLD. However, these findings need to be validated by future studies.

Real-world outcomes of NSCLC patients receiving tissue or circulating tumor DNA-guided osimertinib treatment.

BACKGROUND: Osimertinib yields significant tumor responses and durations of progression-free survival (PFS) in patients with acquired T790M mutations. However, the evidence supporting liquid biopsy-guided treatment is still limited. This study examined the real-world benefits of osimertinib in patients with tissue or plasma T790M mutations. METHODS: From January 2016 to June 2018, a total of 183 non-small-cell lung cancer patients were enrolled. The presence of the T790M mutation was assessed by either tissue or plasma. The PFS, overall survival, and tumor response rates of the patients were calculated and compared with those of previous clinical trials. RESULTS: T790M mutations were detected in 51.5% of the patients, including 64 of 140 (45.7%) who underwent liquid biopsies and 23 of 29 (79.3%) who underwent tumor biopsies. After excluding those in clinical trials, 46 patients received osimertinib, including 33 with positive plasma and 13 with positive tissue results for T790M mutations. The median PFS was 11.3 months (interquartile range: 5.2-NR) in all the T790M-positive patients and 10.1 months (interquartile range: 5.9-NR) in the plasma T790M-positive patients. The overall survival, meanwhile, was not reached, whereas the one-year survival rate was 66.1% in all the patients and 61.4% in those who were plasma T790M-positive. The objective response rate and disease control rate were 37.8% and 91.9% in all the patients and 34.6% and 92.3% in the plasma T790M-positive group, respectively. Using a Cox proportional hazards regression, we determined that male gender was a poor prognostic factor for PFS. CONCLUSIONS: In this retrospective real-world analysis, it was determined that both tissue and plasma T790M mutations can be used to guide treatment with osimertinib. Similar disease control rates and survival durations were observed in comparison to those of phase 3 clinical trials.

Use of recommended posttreatment services for adolescent and young adult survivors of Hodgkin lymphoma.

BACKGROUND: Hodgkin lymphoma (HL) is a leading cancer diagnosis for adolescents and young adults (AYAs), with an overall 5-year survival rate of >80%. However, to the authors' knowledge, little is known regarding posttreatment patterns of care. In the current study, the authors characterized the use of guideline-recommended services in a cohort of AYA survivors of HL in Kaiser Permanente Southern California. METHODS: Patients with HL who were diagnosed between ages 15 and 39 years between 2000 and 2010 were identified. The authors calculated the number of patients who received recommended short-term care within 2 years after treatment cessation for those who remained enrolled and alive from 2001 through 2015. Use of recommended late-effects screening for breast cancer and cardiovascular disease was examined. Logistic regression was used to evaluate the association between receipt of recommended care and patient, cancer, and treatment characteristics. RESULTS: A total of 354 patients were identified, with a mean age at the time of diagnosis of 26 years (standard deviation, 6.9 years). Approximately 12% of patients had stage I disease, 59% had stage II disease, 17% had stage III disease, and 13% of patients had stage IV disease. Nearly all patients received chemotherapy (95%), 51% received radiotherapy, and 5% received care from a pediatric oncologist. Overall, approximately 49% of patients received recommended short-term care. Of those patients eligible for cardiovascular screening at 10 years posttreatment (60 patients), 53% received at least 1 screening. Of those patients eligible for breast cancer screening (21 patients), approximately 50% underwent at least 1 screening. Regression results indicated that those patients treated by a pediatric oncologist were >3 times as likely to receive recommended short-term care. CONCLUSIONS: The results of the current study highlight gaps in the delivery of posttreatment care to AYA survivors of HL. By determining areas in need of improvement, these findings can guide the development of tailored interventions with which to improve care.

Preventing and treating brain metastases with three first-line EGFR-tyrosine kinase inhibitors in patients with EGFR mutation-positive advanced non-small cell lung cancer.

INTRODUCTION: Brain metastases (BM) are common in advanced non-small cell lung cancer (NSCLC), and the prognosis is poor with few therapeutic options. This study evaluated the efficacy of three epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in preventing and treating BM in patients with EGFR mutation-positive advanced NSCLC. METHODS: Patients with EGFR mutation-positive advanced NSCLC who visited a tertiary referral center from 1 December 2013 to 30 November 2017 were analyzed retrospectively. They received gefitinib, erlotinib, or afatinib until disease progression, death, or intolerable adverse events. The cumulative incidence of subsequent BM of initial non-BM patients, progression-free survival (PFS), and overall survival (OS) of the BM and non-BM patients were estimated and compared using the Kaplan-Meier and log-rank tests. RESULTS: 306 NSCLC patients were enrolled, with 116, 75, and 115 receiving first-line gefitinib, erlotinib, and afatinib, respectively. The afatinib group had a better PFS [12.7 versus 9.8 months; hazard ratio (HR) 0.59, p = 0.001] and OS (39.1 versus 22.0 months; HR 0.64, p = 0.035) than the gefitinib group. Afatinib tended to provide better BM prevention than gefitinib (BM cumulative incidence, HR 0.49; 95% confidence interval 0.34-0.71, p < 0.001) according to a Cox model adjusted for possible confounders. Patients with initial BM had a shorter PFS (p < 0.001) and OS (p = 0.015) than those without initial BM. Among the former, there were no differences in median PFS (p = 0.34) and median OS (p = 0.46) in the three EGFR-TKI groups. CONCLUSIONS: Our data suggested that, compared with gefitinib, afatinib provided better benefits significantly in terms of PFS and OS. Both had the same effectiveness in preventing subsequent BM.

The impact of EGFR mutations on the incidence and survival of stages I to III NSCLC patients with subsequent brain metastasis.

Previous studies have demonstrated the association between EGFR mutations and distant metastasis. However, the association for subsequent brain metastasis (BM) in stages I-III non-small cell lung cancer (NSCLC) patients remains inconclusive. We conducted a retrospective analysis to clarify the impact of EGFR mutations on the incidence of BM and associated survival in patients with stage I-III NSCLC. A total of 491 patients screened for EGFR mutations were retrospectively enrolled. Brain MRI or CT was used to detect the BM. Cumulative incidence of subsequent BM and overall survival (OS) after diagnosis of BM were estimated by the Kaplan-Meier method and compared using log-rank test. We performed Cox proportional hazard regression for predictors of subsequent BM and determinants of OS after BM. The cumulative incidence of BM seemed higher in patients harboring EGFR mutations than those without EGFR mutations although it did not reach statistical significance (hazard ratio [HR] = 1.75, 95% confidence interval [CI] = 0.73~1.81). After adjusting possible confounders, including age, smoking, stage, and tumor size, EGFR mutation became one of the predictors for subsequent BM (HR = 1.89, 95% CI = 1.12~3.17, p = 0.017). Though there was no statistical difference in survival after BM between patients with EGFR mutations and wild-type EGFR (median survival: 17.8 vs. 12.2 months, HR = 0.79, 95% CI = 0.45-1.40), patients with EGFR 19 deletion (Del) tended to have a longer survival after BM than the non-EGFR 19 Del group (median survival: 29.4 vs. 14.3 months, HR 0.58, 95% CI = 0.32-1.09, p = 0.089). In conclusion, our data suggested EGFR mutation to be one of the predictors for subsequent BM in stage I-III patients. Given the small sample size, more studies are warranted to corroborate our results.

Ruxolitinib/nilotinib cotreatment inhibits leukemia-propagating cells in Philadelphia chromosome-positive ALL.

BACKGROUND: As one of the major treatment obstacles in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL), relapse of Ph+ALL may result from the persistence of leukemia-propagating cells (LPCs). Research using a xenograft mouse assay recently determined that LPCs were enriched in the CD34+CD38-CD58- fraction in human Ph+ALL. Additionally, a cohort study demonstrated that Ph+ALL patients with a LPCs phenotype at diagnosis exhibited a significantly higher cumulative incidence of relapse than those with the other cell phenotypes even with uniform front-line imatinib-based therapy pre- and post-allotransplant, thus highlighting the need for novel LPCs-based therapeutic strategies. METHODS: RNA sequencing (RNA-Seq) and real-time quantitative polymerase chain reaction (qRT-PCR) were performed to analyze the gene expression profiles of the sorted LPCs and other cell fractions from patients with de novo Ph+ALL. In order to assess the effects of the selective BCR-ABL and/or Janus kinase (JAK)2 inhibition therapy by the treatment with single agents or a combination of ruxolitinib and imatinib or nilotinib on Ph+ALL LPCs, drug-induced apoptosis of LPCs was investigated in vitro, as well as in vivo using sublethally irradiated and anti-CD122-conditioned NOD/SCID xenograft mouse assay. Moreover, western blot analyses were performed on the bone marrow cells harvested from the different groups of recipient mice. RESULTS: RNA-Seq and qRT-PCR demonstrated that JAK2 was more highly expressed in the sorted LPCs than in the other cell fractions in de novo Ph+ALL patients. Combination treatment with a selective JAK1/JAK2 inhibitor (ruxolitinib) and nilotinib more effectively eliminated LPCs than either therapy alone or both in vitro and in humanized Ph+ALL mice by reducing phospho-CrKL and phospho-JAK2 activities at the molecular level. CONCLUSIONS: In summary, this pre-clinical study provides a scientific rationale for simultaneously targeting BCR-ABL and JAK2 activities as a promising anti-LPCs therapeutic approach for patients with de novo Ph+ALL.
