RESUMEN

AIMS: Surveillance for hepatocellular carcinoma (HCC) is recommended for patients with cirrhosis. Multiple risk scores aim to stratify HCC risk, potentially allowing individualized surveillance strategies. We sought to validate four risk scores and quantify the consequences of surveillance via the calculation of numbers needed to benefit (NNB) and harm (NNH) according to classification by risk score strata. METHODS: Data were collected on 482 patients with cirrhosis during 2013-2014, with follow-up until 31/12/2019. Risk scores (aMAP, Toronto risk index, ADRESS HCC, HCC risk score) were derived from index clinic results. The area under the receiving operating characteristic curve (AUC) was calculated for each. Additionally, per-risk strata, NNB was calculated as total surveillance ultrasounds per surveillance diagnosed early HCC (stage 0/A) and NNH as total ultrasounds performed per false positive (abnormal surveillance with normal follow-up imaging). RESULTS: 22 (4.6%) patients developed HCC. 77% (17/22) were diagnosed through surveillance, of which 13/17 (76%) were early stage. There were 88 false positives and no false negatives (normal surveillance result however subsequent HCC detection). Overall NNB and NNH were 241 and 36, respectively. No score was significantly superior using AUC. Patients classified as low risk demonstrated no surveillance benefit (AMAP, THRI) or had a high NNB of > 300/900 (ADRESS HCC, HCC risk score), with low NNH (24-38). CONCLUSION: Given the lack of benefit and increased harm through false positives in low-risk groups, a risk-based surveillance strategy may have the potential to reduce patient harm and increase benefit from HCC surveillance. CLINICAL TRIALS REGISTRATION: This was not a clinical trial and the study was not pre-registered.

RESUMEN

BACKGROUND: Therapy choices in relapsed/refractory multiple myeloma (RRMM) should consider patient satisfaction with treatment, because it is associated with adherence to therapy, health outcomes, and medical safety. The primary objective of this pilot cross-sectional observational study was to ascertain factors associated with patient-reported treatment satisfaction in RRMM. PATIENTS AND METHODS: Patients with a self-reported diagnosis of RRMM recruited from PatientsLikeMe, MyelomaCrowd, and Facebook were administered an electronic survey that included questions on demographics and clinical history, treatment experience, economic burden, and standardized patient-reported outcome measures, including the Treatment Satisfaction Questionnaire for Medication, Eastern Cooperative Oncology Group performance status (ECOG PS) measure, and Work Productivity and Activity Impairment Questionnaire: Specific Health Problem V2.0. Univariable and multivariable analyses were used to identify predictors of patient-perceived treatment satisfaction. RESULTS: One hundred sixty patients with RRMM participated in the study, with a median of two prior relapses and 66.3% reporting the most recent relapse within the last 12 months. ECOG PS ≥2 was associated with lower patient-reported global satisfaction and perceived effectiveness of current treatment. In addition to shorter time spent receiving therapy, orally administered treatment was the strongest predictor of higher satisfaction with treatment convenience. For patients receiving an injectable drug-containing regimen versus an all-oral regimen, respectively, time spent receiving multiple myeloma-directed therapy was higher (12.6 vs. 4.0 hours per month), and total monthly indirect costs were $1,033 and $241. CONCLUSION: Poor ECOG PS was linked to reduced treatment satisfaction and perceived effectiveness of current therapy, whereas an all-oral regimen was associated with increased treatment convenience satisfaction. IMPLICATIONS FOR PRACTICE: This study suggests that attributes including better Eastern Cooperative Oncology Group performance status, less time spent receiving treatment, and oral route of treatment administration lead to higher patient-perceived satisfaction with relapsed/refractory multiple myeloma (RRMM) treatment. Oral route of administration was also associated with less time spent receiving treatment and reduced economic burden for patients. Increased attention to these factors in shared treatment decision making is warranted to help identify individual patient needs, preferences, and expectations for RRMM treatments, to resolve dissatisfaction issues, and to improve the experience of patients with RRMM.

RESUMEN

We report a facile two-step methodology; electrospinning followed by high temperature treatment, to produce manganese oxide-based nanofibers with well-controlled nanoscale architectures. Electrospinning of manganese acetate-based solution (MnOx precursor) has been utilized to fabricate meso-porous manganese oxide nanofibers. These fibers have diameters of about 200-300 nm and fiber mats have been shown to have specific surface area of over 12 m2/g. Scanning and transmission electron microscopy results show that electrospinning has been successfully utilized to create nanofibers with deep inter-connected internal meso-pores for high surface area. In addition, fibers have been spun in a co-axial arrangement to fabricate hollow meso-porous nanofibers, or to develop core-shell nanofibers with nanoparticles of manganese oxides decorated over current conducting carbon core. X-ray diffraction analysis of the oxide fibers confirms the presence of manganese oxides (MnO2, Mn3O4) after calcination at 700 degrees C. These architectures, we believe, are potentially favorable for use in Li-ion batteries, Li-air batteries and supercapacitors.

RESUMEN

Introduction: Donation after circulatory death (DCD) is rapidly increasing in the United States. Detailed data outlining the process from referral to organ transplantation is lacking. Project Aims: We sought to quantify differences at each stage along the referral to donation pathway by donor type. Additionally, we examined factors associated with successful DCD organ utilization. Design: This program evaluation analyzed data from a single organ procurement organization in 2018 to assess demographic and clinical predictors of progression through the donation process, including the role of first-person authorization in DCD. Descriptive statistics were examined by donation stage for demographic characteristics using chi-square; univariate and multivariate logistic regression was used to model predictors of utilization and authorization by organ type, respectively. Results: There were 2466 organ donation referrals during 2018, including 575 donations after brainstem death (DBD), 1890 controlled DCD referrals, and 1 uncontrolled DCD referral. Univariate and multivariate logistic regression models highlighted differences in authorization rates by donor type (DCD vs DBD) and by age, race, and ethnicity. Next-of-kin authorization was declined in 23% of first-person authorized potential DCD, highlighting issues related to the role of donor registration in DCD. Pre-mortem heparin administration was predictive of DCD organ utilization; donor age and warm ischemia time of less than 30 min was statistically significantly associated with DCD extra-renal organ utilization. Conclusion: These results provided insight into strategies for increasing authorization and transplantation of organs from DCD donors and identified areas of improvement for process standardization and policy development.

RESUMEN

INTRODUCTION: This study set out to examine the association between deprivation and the incidence of HCC and survival following diagnosis in the West of Scotland. METHODS: Data were gathered on patients from the prospective West of Scotland regional HCC database from November 2014 to August 2017. Patients were included if they had a new diagnosis of HCC. Data on deprivation were taken from the Scottish Index of Multiple Deprivation (SIMD) 2016. RESULTS: 357 patients were included in the study. There was a higher incidence rate in patients in SIMD quintile 1 (most deprived) compared with quintile 5 (least deprived) (8.4 vs 4.3 per 100,000, respectively, p < 0.0002). There was no difference in stage at diagnosis, treatment intent, or survival, between patients in the most deprived and least deprived quintiles (median survival 368 days vs 325 days, p = 0.8). CONCLUSION: Living in the most deprived areas of the West of Scotland was associated with approximately a twofold increase in the incidence of HCC. However, in contrast to previous research, there was no difference in survival following diagnosis between patients living in the most and least deprived areas.

RESUMEN

OBJECTIVES: This observational study identified attributes of patient-reported satisfaction with therapy for multiple myeloma (MM), described the treatment-related time burden and indirect costs, and investigated the effect of administration route (oral vs. injectable) on these outcomes among patients with newly diagnosed MM (NDMM) and among caregivers. METHODS: Patients residing in the USA with a self-reported diagnosis of NDMM were recruited from PatientsLikeMe, MyelomaCrowd, and Facebook (16 December 2016 and 6 July 2017) to complete an electronic survey including questions on treatment experience, economic burden, and standardized patient-reported outcome measures, including the Treatment Satisfaction Questionnaire for Medication with three domains (global satisfaction, effectiveness, and convenience) and the Work Productivity and Activity Impairment Questionnaire. Univariate and multivariate analyses identified predictors of patient-perceived treatment satisfaction. RESULTS: Among 188 patients, worse Eastern Cooperative Oncology Group performance status (ECOG PS) was correlated with lower patient-perceived effectiveness and convenience of their current treatment. White race and oral administration route were independently correlated with higher patient-perceived convenience of treatment. Injectable therapy use was associated with a trend towards increased activity impairment (43 vs. 34%; p = 0.05) and significantly higher time burden of treatment administration, with threefold higher adjusted indirect costs of MM therapy compared with solely orally administered therapies (monthly mean $US482 vs. 153; 2016 values; p < 0.0001). CONCLUSIONS: Factors associated with patient-perceived satisfaction with NDMM treatment-ECOG PS, race, administration route-warrant increased attention in shared treatment decision making to help identify patient needs and improve the patient's treatment experience. The use of orally administered therapies could improve patients' activity impairment and reduce the time burden associated with therapy.

RESUMEN

AIM: To compare pharmacogenetic test predictions with self-reported treatment experience and side effect tolerability among patients with depression taking psychotherapeutic medications. METHODS: Subjects completed a survey recalling medication effectiveness and side effects and then underwent pharmacogenetic testing. RESULTS: Our 15 gene pharmacogenetic panel predicted efficacy (p < 0.001) but did not predict side effect tolerability (p = 0.70) in a group of 352 patients. The pharmacogenetic panel and reported efficacy corresponded 60% of the time and medication tolerability agreed 71% of the time. CONCLUSION: Pharmacogenetic testing may be a useful adjunct to predict efficacy of medications used to treat depression.

RESUMEN

BACKGROUND: Chorea is the hallmark motor feature of Huntington disease (HD) and can negatively impact daily functioning and health-related quality of life (HRQoL). OBJECTIVE: The objective of this study was to evaluate how chorea impacts HRQoL and overall functioning among HD patients participating on the PatientsLikeMe website ( www.PatientsLikeMe.com ). METHODS: A survey was provided to HD participants and/or their caregivers via PatientsLikeMe (9 February 2017-22 March 2017), comprising multiple-choice and open-ended questions designed to assess how chorea impacts HRQoL and overall functioning, and the importance of treating chorea. The HDQLIFE measurement system was used to evaluate patient-reported outcomes of chorea and compare Anxiety and Stigma scores in participants with high chorea versus those with low chorea [HDQLIFE Chorea scores ≥ 60 (n = 45) vs. < 60 (n = 38)]. RESULTS: A total of 115 participants (n = 35 caregivers; n = 80 individuals with HD) were included in this study. Among those experiencing chorea (n = 83, 74% of respondents), 66% indicated it was 'Very Important' to manage chorea; however, only 47% agreed that their current medication regimen helped manage their movements. In general, respondents reported that chorea negatively affected HRQoL [HDQLIFE Chorea mean score (standard deviation): 59.3 (6.1)]. Consistent with this, significantly higher Anxiety (P = 0.0423) and stigma (P < 0.0001) scores were observed among respondents with high chorea than in those with low chorea. CONCLUSIONS: These results highlight the negative impact of chorea on HRQoL and overall functioning in individuals with HD. Better chorea treatment options are needed to successfully manage symptoms and to help improve HRQoL in these individuals, and patient experiences of anxiety and stigma should be considered in treatment plans.

RESUMEN

BACKGROUND AND OBJECTIVES: In 1998, the California Department of Health Services invited all healthcare facilities in California (n = 2,532) to participate in a statewide, voluntary sharps injury surveillance project. The objectives were to determine whether a low-cost sharps registry could be established and maintained, and to evaluate the circumstances surrounding sharps injuries in California. RESULTS: Approximately 450 facilities responded and reported a total of 1,940 sharps-related injuries from January 1998 through January 2000. Injuries occurred in a variety of healthcare workers (80 different job titles). Nurses sustained the highest number of injuries (n = 658). In hospital settings (n = 1,780), approximately 20% of the injuries were associated with drawing venous blood, injections, or assisting with a procedure such as suturing. As expected, injuries were caused by tasks conventionally related to specific job classifications. The overall results approximate those reported by the Centers for Disease Control and Prevention's National Surveillance System for Health Care Workers and the University of Virginia's Exposure Prevention Information Network. CONCLUSION: These data further support findings from previous studies documenting the complex and persistent nature of sharps-related injuries in healthcare workers. In the future, mandated reporting using standardized forms and consistent application of decision rules would facilitate a more thorough analysis of injury events.

RESUMEN

BACKGROUND: In 1999, licensed health care facilities in California (N = 2532) were invited to participate in a survey about occupational bloodborne pathogens exposure surveillance activities, recordkeeping methods, and use of safety-enhanced sharps devices. RESULTS: A total of 1274 facilities responded to the survey from January 1999 through August 1999 (response rate = 50%). Sharps-related injuries were recorded for multiple departments on various forms in diverse manners. Only 66% of hospitals, 37% of home health agencies, and 33% of skilled nursing facilities reported sharps injuries on a mandated sharps injury log. More than 70% of facilities stated that they used some type of safety device or needleless system, but this figure varied by type of device and facility type. Eighty-four percent of general acute care hospitals, 28% of home health agencies and skilled nursing facilities each had evaluated at least 1 safety-enhanced device. Almost 90% of all facilities expressed a need for educational materials on topics such as device selection and evaluation. CONCLUSIONS: Standardization of surveillance and recordkeeping activities does not exist across facility types. Standards and regulations demand complex recordkeeping activities. Increased funding for distribution of educational materials and on-site training should accompany changes in mandated reporting activities when appropriate. Increased testing and evaluation of devices across facility types are necessary to ensure that safety-enhanced devices are protective of health care workers and patients.
