Factors influencing self-care behaviour in patients with heart failure: Grit as a behavioural support factor.

AIMS: This study aimed to examine the relationship between heart failure knowledge, self-efficacy, social support, grit and self-care behaviour in patients with heart failure and to identify factors associated with patients' self-care behaviour. BACKGROUND: Most patients with heart failure are not as active in implementing self-care behavioural practices as recommended by the guidelines. DESIGN: This descriptive cross-sectional study was designed based on Bandura's Social Cognitive Theory. METHODS: This study included 138 patients who were diagnosed with heart failure in an outpatient department of cardiology at a tertiary hospital in Korea. Data were collected between July and October 2020 using a structured questionnaire and electronic medical records. Data were analysed using the SPSS/WIN 27.0 program. RESULTS: Grit had the strongest association with self-care behaviour among patients with heart failure, followed by social support, self-efficacy and heart failure knowledge. These variables accounted for approximately 52% of the variance in self-care behaviour. CONCLUSIONS: Health-care professionals should assess patients' grit and develop patient-tailored grit enhancement programmes. Based on the social cognitive theory, nursing intervention programmes that can simultaneously manage cognitive (knowledge and self-efficacy), social and environmental (social support) and behavioural support (grit) factors should be developed and applied to nursing practices to promote self-care.

Proton pump inhibitors associated with an increased risk of mortality in elderly: a systematic review and meta-analysis.

PURPOSE: The increased use of proton pump inhibitors (PPIs) in the elderly has raised concerns about potential severe adverse effects. Our systematic review investigated the mortality associated with PPI use in elderly populations. METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library for relevant publications until August 2022. We included randomized controlled trials (RCTs), quasi-RCTs, and observational studies on the association between proton pump inhibitors and mortality in the elderly. To estimate the pooled relative risk (RR) and 95% confidence interval (CI), the inverse-variance random effect model was used. Heterogeneity was assessed using the I2 test. Subgroup analyses were performed by follow-up period, population, and study design. RESULTS: A total of 4 RCTs and 36 cohort studies were included in the meta-analysis. Four RCTs showed that there was no significant association between PPIs and the risk of death. From 23 observational studies (26 cohorts), the use of proton pump inhibitors was not significantly associated with increased mortality in the elderly (RR 1.14; 95% CI, 0.90-1.45). However, when controlling for covariates from 33 observational studies (41 cohorts), proton pump inhibitors in older adults aged 50 years or more were significantly associated with a 15% higher risk of mortality compared to nonusers (RR 1.15; 95% CI, 1.10-1.20). CONCLUSIONS: Our meta-analysis of RCTs found that PPIs did not show a significant association with increased mortality risk in older adults. However, the meta-analysis of cohort studies and long-term follow-up studies showed a higher increased risk of death with PPI use in older adults. The prescription of PPIs in patients aged 50 years or older should be carefully considered.

An economic evaluation of pharmacopuncture versus usual care for chronic neck pain: a pragmatic randomized controlled trial.

BACKGROUND: This study aimed to evaluate the cost utility of pharmacopuncture in comparison with usual care for patients with chronic neck pain. METHODS: A 12-week, multicenter, pragmatic randomized controlled trial was conducted, and 101 patients suffering from chronic neck pain for more than six months were randomly placed into the pharmacopuncture and usual care groups to receive four weeks of treatment and 12 weeks of follow-up observations. The quality-adjusted life year (QALY) was calculated using EQ-5D and SF-6D. Concerning costs in 2019, a primary analysis was performed on societal perspective cost, and an additional analysis was performed on healthcare perspective cost. RESULTS: Compared to usual care, pharmacopuncture was superior as it showed a slightly higher QALY and a lower incremental cost of $1,157 from a societal perspective. The probability that pharmacopuncture would be more cost-effective at a willingness-to-pay (WTP) of $26,374 was 100%. Pharmacopuncture was also superior from a healthcare perspective, with a lower incremental cost of $26. The probability that pharmacopuncture would be more cost-effective at a WTP of $26,374 was 83.7%. CONCLUSIONS: Overall, pharmacopuncture for chronic neck pain was found to be more cost-effective compared to usual care, implying that clinicians and policy makers should consider new treatment options for neck pain.

Hepatitis C Cascade of Care in the Direct-Acting Antivirals Era: A Meta-Analysis.

INTRODUCTION: The hepatitis C virus (HCV) epidemic remains a public health problem worldwide. A systematic review and meta-analysis were conducted to provide evidence of outcomes attained across the HCV care cascade in the era of direct-acting antivirals. METHODS: Studies from North America, Europe, and Australia (January 2014 through March 2021) reporting on HCV care cascade outcomes (screening to cure) were included. When calculating the proportions of individuals completing each step, the numerator for Steps 1-8 was the number of individuals completing each step; the denominator was the number of individuals completing the previous step for Steps 1-3 and Step 3 for Steps 4-8. In 2022, random effects meta-analyses were conducted to estimate pooled proportions with 95% CIs. RESULTS: Sixty-five studies comprising 7,402,185 individuals were identified. Among individuals with positive HCV ribonucleic acid test results, 62% (95% CI=55%, 70%) attended their first care appointment, 41% (95% CI=37%, 45%) initiated treatment, 38% (95% CI=29%, 48%) completed treatment, and 29% (95% CI=25%, 33%) achieved cure. HCV screening rates were 43% (95% CI=22%, 66%) in prisons or jails and 20% (95% CI=11%, 31%) in emergency departments. Linkage to care rates were 62% (95% CI=46%, 75%) for homeless individuals and 26% (95% CI=22%, 31%) for individuals diagnosed in emergency departments. Cure rates were 51% (95% CI=30%, 73%) in individuals with substance use disorder and 17% (95% CI=17%, 17%) in homeless individuals. Cure rates were lowest in the U.S. DISCUSSION: Despite the availability of effective all-oral direct-acting antiviral therapies, persistent gaps remain across the HCV care cascade, especially among traditionally marginalized populations. Public health interventions targeting identified priority areas (e.g., emergency departments) may improve screening and healthcare retention of vulnerable populations with HCV infection (e.g., substance use disorder populations).

Impact of Direct-acting Antivirals on Hepatocellular Carcinoma and Mortality Among Medicaid Beneficiaries With Hepatitis C.

OBJECTIVE: The effects of all-oral direct-acting antivirals (DAAs) on hepatocellular carcinoma (HCC) and liver-related and all-cause mortality were assessed among Medicaid beneficiaries with hepatitis C virus (HCV). SUBJECTS: This cohort study used 2013-2019 Arizona Medicaid data from beneficiaries with HCV aged 18-64 years. METHODS: Risks of HCC and liver-related and all-cause mortality were compared between patients with or without DAA treatment, stratified by liver disease severity, using inverse probability of treatment weighted multivariable Cox proportional hazards regression models. RESULTS: Of 29,289 patients, 13.3% received DAAs. Among patients with compensated cirrhosis (CC), DAA treatment was associated with a lower risk of HCC [adjusted hazard ratio (aHR), 0.57; 95% CI, 0.37-0.88] compared with untreated patients although this association was not statistically significant for patients without cirrhosis or with decompensated cirrhosis (DCC). Compared with untreated patients, DAA treatment was associated with decreased risk of liver-related mortality for patients without cirrhosis (aHR: 0.02; 95% CI: 0.004-0.11), with CC (aHR: 0.09; 95% CI: 0.06-0.13), or with DCC (aHR: 0.20; 95% CI: 0.14-0.27). Similarly, compared with untreated patients, DAA treatment was associated with lower all-cause mortality for patients without cirrhosis (aHR: 0.10; 95% CI: 0.08-0.14), with CC (aHR: 0.07; 95% CI: 0.05-0.10), or with DCC (aHR: 0.15; 95% CI: 0.11-0.20). CONCLUSIONS: Among Arizona Medicaid beneficiaries with HCV, DAA treatment was associated with decreased risk of HCC for patients with CC but not for patients without cirrhosis or with DCC. However, DAA treatment was associated with decreased risk of liver-related and all-cause mortality.

Disparities in Access to Hepatitis C Treatment Among Arizona Medicaid Beneficiaries With Chronic Hepatitis C.

BACKGROUND: High costs of direct-acting antivirals (DAAs) have led to their restricted access for patients with hepatitis C virus (HCV). OBJECTIVE: The aim was to assess how HCV treatment access and predictors of HCV treatment changed in the post-DAA period compared with pre-DAA period. METHODS: A retrospective cohort study using Arizona Medicaid data was conducted for patients with HCV to compare treatment initiation rates between pre-DAA (January 2008-October 2013) and post-DAA (November 2013-December 2018) periods. Multivariable logistic regression was used, controlling for demographic and clinical variables. RESULTS: Twenty-four thousand and ninety and 28,756 patients during the pre-DAA and post-DAA periods were identified. Overall, 12.6% were treated in the post-DAA period compared with 7.8% in the pre-DAA period ( P <0.001). The relative increase in the HCV treatment initiation rate from the pre-DAA to the post-DAA period was significant greater for Black beneficiaries compared with White beneficiaries ( P =0.002). Hispanic beneficiaries were less likely to be treated in the post-DAA period [adjusted odds ratios (aOR): 0.88; CI: 0.79-0.98] compared with White beneficiaries. Those with mental illness (aOR: 0.71; 95% CI: 0.63-0.80) and substance use disorders (aOR: 0.63; 95% CI: 0.58-0.68) were less likely to be treated in the post-DAA period. CONCLUSIONS: Although treatment initiation increased and disparities for Black beneficiaries compared with White beneficiaries attenuated in the post-DAA period, only 13% of Arizona Medicaid patients with HCV received DAA treatment. Disparities in DAA access remained among Hispanic patients and those with mental illness and substance use disorders.

Cost-Utility Analysis of Chuna Manual Therapy and Usual Care for Chronic Neck Pain: A Multicenter Pragmatic Randomized Controlled Trial.

This study aimed to compare the cost-effectiveness of manual therapy and usual care for patients with chronic neck pain. A cost-utility analysis alongside a pragmatic randomized controlled trial was conducted in five South Korean hospitals. Data were procured from surveys and nationally representative data. Participants were 108 patients aged between 19 and 60 years, with chronic neck pain persisting for at least 3 months and a pain intensity score of ≥5 on the numerical rating scale in the last 3 days. The study was conducted for 1 year, including 5 weeks of intervention and additional observational periods. Participants were divided into a manual therapy (Chuna) group and a usual care group, and quality-adjusted life-years, costs, and the incremental cost-effectiveness ratio were calculated. The quality-adjusted life-years of the manual therapy group were 0.024 higher than that of the usual care group. From the societal perspective, manual therapy incurred a lower cost-at $2,131-and was, therefore, the more cost-effective intervention. From a healthcare system perspective, the cost of manual therapy was higher, with an incremental cost-effectiveness ratio amount of $11,217. Manual therapy is more cost-effective for non-specific chronic neck pain management from both a healthcare system and societal perspective.

A National Catalog of Mapped Short-Form Six-Dimension Utility Scores for Chronic Conditions in the United States From 2010 to 2015.

OBJECTIVES: This study examined health preference utility weights and utility decrements associated with different types of chronic conditions in the United States. METHODS: We used the 2010-2015 Medical Expenditure Panel Survey data for persons aged ≥ 18 years with 12-Item Short-Form Survey Physical and Mental Component Summary scores. 12-Item Short-Form Survey scores were converted to Short-Form Six-Dimension (SF-6D) preference scores to measure utilities of different chronic diseases. We used the Clinical Classification Code to identify 30 chronic diseases from 12 categories, such as cardiovascular diseases, cerebrovascular diseases, hypertension, hyperlipidemia, obesity, cancers, musculoskeletal diseases, endocrine or metabolic diseases, oral diseases, respiratory diseases, and mental disorders. A generalized linear model was used to quantify the utility decrements for 30 chronic diseases, controlling for demographic characteristics. RESULTS: We identified 132 737 adults (mean age 47.2 years, 52.2% female, 80% white); 73% had at least one identified chronic disease, and the mean SF-6D was 0.786. Among 30 chronic diseases, the unadjusted mean SF-6D scores of patients with cognitive disorder (0.607) were the lowest, followed by congestive heart failure (0.629), rheumatoid arthritis (0.654), and lung cancer (0.662). After controlling for demographic variables (ie, age, sex) and comorbidities, cognitive disorders (-0.116), mood disorders (-0.099), rheumatoid arthritis (-0.090), liver cancer (-0.078), and stroke (-0.063) showed the highest decrements in the SF-6D scores (P < .05). CONCLUSIONS: This study provides a nationally representative catalog of utility weights for major chronic diseases in the US general population. The utility decrements will enable researchers to calculate the health utilities of patients with multiple comorbid diseases.

Analysis of outpatient expenditure trends using Korean Health Panel Survey data of patients diagnosed with lumbar intervertebral disc herniation.

OBJECTIVE: In this study, we aimed to analyze cost trends for the outpatient treatment of lumbar intervertebral disc herniation (LDH). METHODS: We used cross-sectional data obtained from the Korea Health Panel Survey from 2011 to 2015. We compared outpatient medical expenses for conservative treatment of LDH using traditional Korean medicine (TKM) or Western medicine (WM). RESULTS: This analysis revealed that the total medical expenses for outpatient treatment of LDH using WM treatment methods increased by 30% from 2011 to 2015, and self-payment expenses increased by 50%. The total medical expenses for outpatient treatment of LDH using TKM methods increased by 8%, and self-payment expenses decreased by 33%. The National Health Insurance Service (NHIS) expenditure for WM increased by 7%, and non-covered costs increased by 83%. The NHIS expenditure for TKM increased by 41%, and non-covered costs decreased by 66%. CONCLUSIONS: The total medical expenses for WM treatments are increasing in Korea, especially for non-covered treatments. The non-covered costs for TKM treatments are decreasing, suggesting a change in medical cost trends according to whether Korea's actual medical expense insurance scheme is applied.

Health-Related Quality of Life and Health Utilities of Mild, Moderate, and Severe Asthma: Evidence from the Medical Expenditure Panel Survey.

BACKGROUND: Little information is known about the health-related quality of life (HRQOL) and the patient's preference values by the severity of asthma. We evaluated the HRQOL and health utility impairment associated with asthma severity using the SF-12 and SF-6D. METHODS: We conducted a cross-sectional analysis of 2010-2016 Medical Expenditure Panel Survey database of asthma patients aged ≥18 years and categorized them into mild, moderate, and severe asthma. Study outcomes included the SF-12 physical component summary (PCS) and mental component summary (MCS) for measuring HRQOL and SF-6D for health utility. Survey regression models were used to estimate HRQOL and utilities for mild, moderate, and severe asthma. RESULTS: Of 10,222 patients with asthma, 75.4%, 23.9%, and 0.8% had mild, moderate and severe asthma. We observed that the greater the severity, the lower the SF-6D scores: 0.731 in mild, 0.723 in moderate, and 0.659 in severe asthma (P < 0.001). Patients with severe asthma had a significantly lower PCS compared to those with mild asthma (-5.3; P < 0.001) but there was no significant difference in MCS (-1.9; P = 0.309) controlling for socioeconomic and clinical variables. Asthma severity, women, older age, and having a lower level education and public insurance were significantly associated with lower PCS (P < 0.01). CONCLUSION: Asthma patients had worse physical HRQOL than mental health, especially patients with severe asthma. These data suggest that the management of physical health of female, older aged, and low education patients with asthma should be focused on improving HRQOL.

The use of all-oral direct-acting antivirals in hepatitis C virus-infected patients with substance use disorders.

BACKGROUND: There is evidence that barriers exist for the initiation of direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) for those with substance use disorders (SUDs). However, real world clinical evidence of DAA treatment initiation following receipt of a prescription and continuation among those with SUDs and HCV is lacking. OBJECTIVES: To (1) compare HCV treatment initiation (prescription fill) rates and early discontinuation rates between HCV-infected patients with and without SUDs in the DAA era, and (2) identify patient-level factors associated with HCV treatment initiation and early discontinuation in patients with SUDs. METHODS: A retrospective cohort analysis of the MarketScan databases (January 2012-December 2018) was conducted for newly diagnosed treatment naïve HCV-infected patients (age ≥ 18) with and without SUDs. We used multivariable Cox regression to estimate adjusted hazard ratios (aHRs) with 95% confidence intervals of treatment initiation and early discontinuation in those with SUDs versus those without. RESULTS: We identified a total of 29,228 newly diagnosed HCV-infected patients (6,385 with SUDs and 22,843 without SUDs). Overall, DAA treatment initiation for patients with SUDs was significantly lower than that for those without SUDs (24% vs 34%; P < 0.01). After adjusting for demographics and clinical characteristics, patients with SUDs were less likely to initiate DAA treatments than those without SUDs (aHR, 0.87 [0.82-0.92]). There was no difference in discontinuation of DAA treatment between those with and without SUDs (4% vs 3%: aHR, 1.13 [0.81-1.60]). Among patients with SUDs (n = 6,385), lower rates of initiating DAA treatment was associated with younger age, and comorbidities including alcoholic liver disease (ALD; aHR, 0.44 [0.33-0.57), chronic kidney disease (CKD) (aHR, 0.52 [0.36-0.75]), and hepatitis B virus (HBV; aHR, 0.64 [0.44-0.92]). DAA treatment discontinuation was associated with younger age, ribavirin (RBV) therapy (aHR, 3.78 [2.21-6.47]), and cirrhosis diagnosis (aHR, 2.42 [1.21-4.84]) but not SUD treatment (aHR, 0.68 [0.34-1.34]). CONCLUSIONS: HCV-infected patients with SUDs had significantly lower treatment initiation rates, especially in young females and those with ALD, CKD, and HBV. No difference was found in DAA discontinuation. However, younger patients with RBV treatment and/or cirrhosis were more likely to stop treatment. Interventions directed towards these groups are needed to enhance DAA initiation and treatment maintenance among HCV-infected patients with SUDs. DISCLOSURES: Research reported in this publication was supported in part by the National Institute on Drug Abuse of the National Institutes of Health under award number K01DA045618 (to Park). The other authors have nothing to disclose that may present a potential conflict of interest.

Direct-Acting Antiviral Treatment Use Remains Low Among Florida Medicaid Beneficiaries With Chronic Hepatitis C.

Medicaid prior authorization (PA) policies for treatment of hepatitis C virus (HCV) with direct-acting antiviral (DAA) therapy are changing. We aimed to evaluate effects of changes in PA requirements on treatment uptake and to determine the factors associated with DAA treatment among Florida Medicaid beneficiaries with HCV. This is a retrospective cohort analysis of Florida's Medicaid administrative claims and electronic medical records (2013-2018). A total of 14,063 newly diagnosed patients with HCV were grouped based on human immunodeficiency virus (HIV) co-infection and/or a substance use disorder (SUD) (7,735 HCV mono-infected with a SUD, 5,180 HCV mono-infected without a SUD, 564 HCV/HIV co-infected with a SUD, and 584 HCV/HIV co-infected without a SUD). Although the treatment rate increased three-fold after June 1, 2016, when a fibrosis-stage restriction was eliminated, only 8% received DAAs. Compared to HCV mono-infected without a SUD, HCV mono-infected with a SUD and HCV/HIV co-infected with a SUD were 47% (adjusted hazard ratio, 0.53; 95% confidence interval, 0.47-0.60) and 59% (adjusted hazard ratio, 0.41; 95% confidence interval, 0.28-0.61) less likely to initiate DAAs. Those with HCV/HIV/SUD did not experience a DAA initiation increase after a fibrosis-stage restriction was eliminated. Compared with Whites, Blacks were less likely to receive DAAs but were more likely to complete treatment. Use of medication-assisted therapy was low, despite those on medication-assisted therapy being 60% more likely to initiate DAA therapy and no more likely to discontinue therapy. Conclusion: Despite changes in Florida's Medicaid PA requirements for DAA treatment, only 8% received treatment. Disparities in treatment access were found among patients with HIV and a SUD, and who were Black.

The Impact of Direct-Acting Antiviral Therapy on End-Stage Liver Disease Among Individuals with Chronic Hepatitis C and Substance Use Disorders.

BACKGROUND AND AIMS: Our aim was to evaluate the impact of direct-acting antivirals (DAAs) on decompensated cirrhosis (DCC) and HCC in patients with chronic HCV and substance use disorder (SUD) compared with those without an SUD. APPROACH AND RESULTS: This retrospective cohort study used the MarketScan database (2013-2018) to identify 29,228 patients with chronic HCV, where 22% (n = 6,385) had ≥1 SUD diagnosis. The inverse probability of treatment weighted multivariable Cox proportional hazard models were used to compare the risk of developing DCC and HCC. Among the those who were noncirrhotic, treatment reduced the DCC risk among SUD (adjusted hazard ratio [aHR] 0.13; 95% CI, 0.06-0.30) and non-SUD (aHR 0.11; 95% CI, 0.07-0.18), whereas the risk for HCC was not reduced for the SUD group (aHR 0.91; 95% CI, 0.33-2.48). For those with cirrhosis, compared with patients who were untreated, treatment reduced the HCC risk among SUD (aHR, 0.33; 95% CI, 0.13-0.88) and non-SUD (aHR, 0.40; 95% CI, 0.25-0.65), whereas the risk for DCC was not reduced for the SUD group (aHR, 0.64; 95% CI, 0.37-1.13). Among patients with cirrhosis who were untreated, the SUD group had a higher risk of DCC (aHR, 1.52; 95% CI, 1.03-2.24) and HCC (aHR, 1.69; 95% CI, 1.05-2.72) compared with non-SUD group. CONCLUSIONS: Among the HCV SUD group, DAA treatment reduced the risk of DCC but not HCC for those who were noncirrhotic, whereas DAA treatment reduced the risk of HCC but not DCC for those with cirrhosis. Among the nontreated, patients with an SUD had a significantly higher risk of DCC and HCC compared with those without an SUD. Thus, DAA treatment should be considered for all patients with HCV and an SUD while also addressing the SUD.

Trends in Sexually Transmitted Infections in United States Ambulatory Care Clinics from 2005-2016.

We examined the prevalence trends of non-human immunodeficiency virus (HIV) sexually transmitted infections (STI) and associated patient characteristics in U.S. ambulatory-care settings from 2005-2016. We conducted a retrospective repeated cross-sectional analysis using data from the National Ambulatory Medical Care Survey (NAMCS) for individuals aged 15-64 with a non-HIV STI-related visit. Data were combined into three periods (2005-2008, 2009-2012, and 2013-2016) to obtain reliable estimates. Logistic regression was used for analysis. A total of 19.5 million weighted, non-HIV STI-related ambulatory visits from 2005-2016 were identified. STI-related visits per 100,000 ambulatory care visits increased significantly over the study period: 206 (95% CI = 153-259), 343 (95% CI = 279-407), and 361 (95% CI = 277-446) in 2005-2008, 2009-2012, and 2013-2016, respectively (Ptrend = 0.003). These increases were mainly driven by increases in HPV-related visits (56 to 163 per 100,000 visits) from 2005-2008 to 2009-2012, followed by syphilis- or gonorrhea-related visits (30 to 67 per 100,000 visits) from 2009-2012 to 2013-2016. Higher odds of having STI-related visit were associated with younger age (aged 15-24: aOR = 4.45; 95% CI = 3.19-6.20 and aged 25-44: aOR = 3.59; 95% CI = 2.71-4.77) vs. 45-64-year-olds, Black race (aOR = 2.41; 95% CI = 1.78-3.25) vs. White, and HIV diagnosis (aOR = 10.60; 95% CI = 5.50-20.27) vs. no HIV diagnosis. STI-related office visits increased by over 75% from 2005-2016, and were largely driven by HPV-related STIs and syphilis- or gonorrhea-related STIs.

Acid-suppressive agents and survival outcomes in patients with cancer: a systematic review and meta-analysis.

BACKGROUND: Patients with cancer often receive acid-suppressive agents (ASAs) to treat common gastroesophageal reflux and peptic ulcer diseases. Our systematic review addresses the association between ASAs and survival outcomes in these patients. METHODS: We searched MEDLINE, EMBASE, and Cochrane until December 2019, including randomized controlled trials (RCTs), quasi-RCTs, and observational studies concerning ASAs that reported progression-free survival (PFS) and/or overall survival (OS). We estimated hazard ratios (HRs) with 95% confidence intervals (CIs) using the random-effects model, and assessed heterogeneity with I2 statistic. RESULTS: We included 45,626 patients from 7 RCTs and 18 observational studies, including esophageal/gastric, colorectal, pancreatic, lung, breast, prostate, kidney, and other cancers. Five studies showed that ASAs in lung cancer patients received tyrosine kinase inhibitors (TKIs) had significantly worse PFS (HR 1.64, 95% CI 1.14 - 2.37, I2 = 57%) and OS (HR 1.13, 95% CI 1.05 - 1.21, I2 = 0%) than nonusers. Each of five studies found no significant association between ASAs and OS in esophageal/gastric (HR 0.91, 95% CI 0.77 - 1.09, I2 = 32%) or colorectal cancer patients (HR 1.33, 95% CI 0.96- 1.85, I2 = 0%). ASAs were not significantly associated with an OS in patients with kidney cancer (HR 1.04, 95% CI 0.96 - 1.13, I2 = 28%). CONCLUSIONS: Meta-analysis showed that ASAs significantly associated with an increased mortality risk in lung cancer patients treated TKIs, but not in patients with esophageal/gastric, colorectal, or kidney cancer. Until further studies confirm these results, caution should be used when administering ASAs and TKIs to patients with lung cancer.

Medical Costs and Productivity Loss Due to Mild, Moderate, and Severe Asthma in the United States.

BACKGROUND: Little is known about economic and productivity loss by severity of asthma. We investigate health-care utilization, direct medical costs, and indirect costs due to productivity loss from asthma by severity. METHODS: We conducted a cross-sectional analysis of the Medical Expenditure Panel Survey database (2010-2017) of patients with asthma aged ≥12 years and categorized them into mild, moderate, and severe asthma groups based on symptom control medications. Study outcomes included health-care utilization, direct medical costs, and indirect costs of asthma-related absenteeism. We used zero-inflated Poisson regression models to estimate incremental health-care utilization and generalized linear models to estimate incremental annual direct medical costs compared to patients without asthma. RESULTS: An estimated 139 million persons had an asthma diagnosis. Of patients with asthma, 77.1%, 22.2%, and 0.7% had mild, moderate, and severe asthma, respectively. Compared to patients without asthma, patients with asthma had incremental mean differences of 4.16 outpatient visits, 0.18 emergency department visits, and 0.07 hospitalizations per year. Annual direct medical costs were significantly associated with asthma severity ($3305 in mild, $7250 in moderate, and $9175 in severe asthma) (P < 0.05). Patients with mild, moderate, and severe asthma reported 0.76, 2.31, and 7.19 missed work or school days, resulting in $106, $321, and $1000 indirect costs per person per year, respectively. CONCLUSION: Asthma-related direct and indirect costs are significantly associated with asthma severity, with severe asthma medical costs being about three times higher than mild. Controlling asthma symptoms is important to reduce the economic and social burden of asthma.

The safety and effectiveness of self-administered coffee enema: A systematic review of case reports.

BACKGROUND: As the self-administration of coffee enema is being used as a mean of self-care for detoxication in various indications, it is important that evidence-based public health information is provided for effective and safe use. However, the evidence is so far rare. This systematic review was conducted to investigate the safety and effectiveness of self-administered coffee enema in a wide range of use, and to provide evidence about its benefits and risks. METHODS: Relevant studies were retrieved from Ovid MEDLINE, Ovid Embase, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature; and also from oriental databases, KoreaMed, Korean Medical Database, Korean Studies Information Service System, National Discovery for Science Leaders, and Korea Institute of Science and Technology Information, Oriental Medicine Advanced Searching Integrated System, China National Knowledge Infrastructure, and Japan Science and Technology Information Aggregator. Considering self-administered coffee enema being used in a various indication, study population was not restricted. Any types of published studies that included outcomes of effectiveness and safety of self-administered coffee enema with or without comparators were eligible for this systematic review. Data on biomedical indications, patient-reported outcomes, and adverse events were collected. Descriptive analyses were planned because diverse health conditions and outcome variables did not allow for quantitative synthesis. RESULTS: Nine case reports that describe adverse events were identified and included in the analysis. Of these, 7 recent ones reported colitis after self-administration, mentioning that the most plausible cause assumed was the coffee fluid itself, which contained numerous chemical substances. Two others reported more critical adverse events. All 9 case reports with acceptable quality of evidence warned against the self-administration of the procedure. No study that reports the effectiveness of coffee enema was found. CONCLUSIONS: Based on the evidences reviewed, this systematic review does not recommend coffee enema self-administration as a complementary and alternative medicine modality that can be adopted as a mean of self-care, given the unsolved issues on its safety and insufficient evidence with regard to the effectiveness.

Effectiveness of high-intensity laser therapy in the management of patients with knee osteoarthritis: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: High-intensity laser therapy (HILT) has recently been used to control pain and symptom improvement in knee osteoarthritis. We performed a systematic review and meta-analysis of randomized controlled trials to assess the effectiveness of HILT in patients with knee osteoarthritis. METHODS: We conducted a search of articles in the MEDLINE, EMBASE, Cochrane CENTRAL, and Web of Science databases up to March 2020 for randomized controlled trials investigating HILT intervention, placebo, or active intervention as comparator groups for alleviating pain in knee osteoarthritis. Two independent reviewers evaluated the methodological quality and extracted pain and functional outcomes using a pre-specified form. A meta-analysis was performed using an inverse-variance random effect model. Heterogeneity was assessed using Higgins I2 with p-values. RESULTS: Six randomized controlled trials (RCTs) were included in this meta-analysis. For VAS pain, 334 patients from four studies showed that HILT significantly decreased pain compared to the control (MD, -1.18; 95% CI, -1.68 to -0.69). HILT significantly improved WOMAC stiffness (SMD -1.00; 95% CI -1.32, -0.68) and function (SMD, -5.36; 95% CI -7.39 to -3.34) compared to the control. CONCLUSION: The effectiveness of HILT on pain, stiffness, and function in patients with knee osteoarthritis is promising. However, due to the limited number of studies, further randomized controlled trials with large, well-designed samples are needed.

The association between acid-suppressive agent use and the risk of cancer: a systematic review and meta-analysis.

BACKGROUND: Acid-suppressive agents (ASAs) may be associated with cancer; previous studies reported that the risk of cancer with acid suppressants has differed depending on the site of cancer. Here, we conducted a systematic review and meta-analysis of the association between ASA use and the type of cancer risk. METHODS: MEDLINE, EMBASE, and Cochrane library databases were searched for publications up to the end of September 2019 for MeSH terms and text words related to cancer and ASAs. Studies on the association between ASAs and cancer risk, which included a control group and reported the relative risk of cancer, were included. The inverse-variance random effect model was used to estimate the pooled relative risk (RR) and 95% confidence interval (CI), and subgroup analysis for type of acid suppressants, drug uptake duration, and cumulative doses was performed. Heterogeneity was assessed using the I2 test and Q statistic. RESULTS: Thirty-nine cohort and case-control studies were included. ASA use was found to be significantly associated with a 46% higher risk of gastric cancer (RR, 1.46; 95% CI, 1.18-1.80) and a 53% higher risk of liver cancer (RR, 1.53; 95% CI, 1.31-1.78) compared with nonuse; however, there was no significant association for esophageal, colorectal, pancreatic, lung, breast, prostate, and kidney cancer; melanoma; and lymphoma. CONCLUSIONS: ASAs were significantly associated with an increased risk of gastric and liver cancer; therefore, special attention of ASA use considering the potential risk of gastric and liver cancer is needed.
