Low diffusion capacity predicts poor prognosis in extensive stage small cell lung cancer: a single-center analysis of 10 years.

BACKGROUND: Poor pulmonary function and chronic obstructive pulmonary disease (COPD) are associated with poorer overall survival (OS) in non-small-cell lung cancer (NSCLC) patients. Few studies have investigated the association between pulmonary function and OS in small-cell lung cancer (SCLC) patients. We compared the clinical characteristics of extensive disease SCLC (ED-SCLC) with or without moderately impaired diffusion capacity for carbon monoxide (DLco) and investigated the factors associated with survival in ED-SCLC patients. METHODS: This retrospective single-center study was performed between January 2011 and December 2020. Of the 307 SCLC patients who received cancer therapy during the study, 142 with ED-SCLC were analyzed. The patients were divided into DLco < 60% group and DLco ≥ 60% groups. OS and predictors of poor OS were analyzed. RESULTS: The median OS of the 142 ED-SCLC patients was 9.3 months and the median age was 68 years. In total, 129 (90.8%) patients had a history of smoking, and 60 (42.3%) had COPD. Thirty-five (24.6%) patients were assigned to the DLco < 60% group. Multivariate analysis revealed that DLco < 60% (odds ratio [OR], 1.609; 95% confidence interval [CI], 1.062-2.437; P = 0.025), number of metastases (OR, 1.488; 95% CI, 1.262-1.756; P < 0.001), and < 4 cycles of first-line chemotherapy (OR, 3.793; 95% CI, 2.530-5.686; P < 0.001) were associated with poor OS. Forty (28.2%) patients received < 4 cycles of first-line chemotherapy; the most common reason for this was death (n = 22, 55%) from grade 4 febrile neutropenia (n = 15), infection (n = 5), or massive hemoptysis (n = 2). The DLco < 60% group had a shorter median OS than the DLco ≥ 60% group (10.6 ± 0.8 vs. 4.9 ± 0.9 months, P = 0.003). CONCLUSIONS: In this study, approximately one quarter of the ED-SCLC patients had DLco < 60%. Low DLco (but not forced expiratory volume in 1 s or forced vital capacity), a large number of metastases, and < 4 cycles of first-line chemotherapy were independent risk factors for poor survival outcomes in patients with ED-SCLC.

Building medication for opioid use disorder prescriber capacity during the opioid epidemic: Prescriber recruitment trends and methods.

INTRODUCTION: Physicians are a critical clinical resource for patient care. Yet physician recruitment has been considerably understudied, particularly in substance use disorder (SUD) settings. This study proposes a conceptual model called the "Physician Recruitment Descriptive Factors Framework" to investigate the role of environmental, organizational, and individual factors in the use of physician recruitment strategies. METHODS: The study setting was 75 sites that provided outpatient SUD treatment services in Florida, Ohio, and Wisconsin from 2016 to 2019. Central to the analysis is the use of five targeted physician recruitment strategies. The study investigated whether financial conditions, location (urban v. non-urban), external implementation coaching, and recruiters' roles influenced use of the targeted physician recruitment strategies. RESULTS: During the study period, a formal plan to recruit physicians was the most common strategy used (n = 67.6 %). The director or chief executive officer (CEO) was most likely to conduct physician recruitment (n = 58.7 %). During the study, use of four of the five recruitment strategies significantly declined (at p ≤ 0.01), while the perceived need for new prescribing capacity significantly declined (p ≤ 0.01), and prescribers per site increased from 1.54 to 3.21. Sixty-four percent of this increase in prescribers was due to more physician prescribers, while 36 % was due to the onset of the ability of advanced nurse practitioners and physician assistants to prescribe buprenorphine. In year 3 of the study, the strategies most closely aligned with the current number of prescribers were conducting weekly outreach to prescriber candidates (p = .018), having a dedicated prescriber recruiter (p = .011), and having a dedicated budget for prescriber recruiting (p = .002). CONCLUSIONS: The study describes which physician recruitment strategies SUD treatment sites used and how the need to recruit physicians for specialty treatment SUD clinics declined as prescriber capacity increased. The proposed multi-level framework provides the scaffolding for future physician recruitment research and practice.

Enhancing Use of Medications for Opioid Use Disorder Through External Coaching.

OBJECTIVE: This randomized controlled trial tested whether external coaching influences addiction treatment providers' utilization of medications to treat opioid use disorder (MOUDs). METHODS: This study recruited 75 unique clinical sites in Florida, Ohio, and Wisconsin, including 61 sites in specialty treatment agencies and 14 behavioral health sites within health systems. The trial used external coaching to increase use of MOUDs in the context of a learning collaborative and compared it with no coaching and no learning collaborative (control condition). Outcome measures of MOUD capacity and utilization were monthly tabulations of licensed buprenorphine slots (i.e., the number of patients who could be treated based on the buprenorphine waiver limits of the site's providers), buprenorphine use, and injectable naltrexone administration. RESULTS: The coaching and control arms showed no significant difference at baseline. Although buprenorphine slots increased in both arms during the 30-month trial, growth increased twice as fast at the coaching sites, compared with the control sites (average monthly rate of 6.1% vs. 3.0%, respectively, p<0.001). Buprenorphine use showed a similar pattern; the monthly growth rate in the coaching arm was more than twice the rate in the control arm (5.3% vs. 2.4%, p<0.001). Coaching did not have an impact on injectable naltrexone, which grew less than 1% in both arms over the trial period. CONCLUSIONS: External coaching can increase organizational capacity for and growth of buprenorphine use. Future research should explore the dimensions of coaching practice, dose, and delivery modality to better understand and enhance the coaching function.

Extending the actor-partner interdependence model to accommodate multivariate dyadic data using latent variables.

This study extends the traditional Actor-Partner Interdependence model (APIM; Kenny, 1996) to incorporate dyadic data with multiple indicators reflecting latent constructs. Although the APIM has been widely used to model interdependence in dyads, the method and its applications have largely been limited to single sets of manifest variables. This article presents three extensions of the APIM that can be applied to multivariate dyadic data; a manifest APIM linking multiple indicators as manifest variables, a composite-score APIM relating univariate sums of multiple variables, and a latent APIM connecting underlying constructs of multiple indicators. The properties of the three methods in analyzing data with various dyadic patterns are investigated through a simulation study. It is found that the latent APIM adequately estimates dyadic relationships and holds reasonable power when measurement reliability is not too low, whereas the manifest APIM yields poor power and high type I error rates in general. The composite-score APIM, even though it is found to be a better alternative to the manifest APIM, fails to correctly reflect latent dyadic interdependence, raising inferential concerns. We illustrate the APIM extensions for multivariate dyadic data analysis by an example study on relationship commitment and happiness among married couples in Wisconsin. In cases where the measures are reliable reflections of psychological constructs, we suggest using the latent APIM for examining research hypotheses that discuss implications beyond observed variables. We conclude with stressing the importance of carefully examining measurement models when designing and conducting dyadic data analyses. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Evaluating sensitivity to classification uncertainty in latent subgroup effect analyses.

BACKGROUND: Increasing attention is being given to assessing treatment effect heterogeneity among individuals belonging to qualitatively different latent subgroups. Inference routinely proceeds by first partitioning the individuals into subgroups, then estimating the subgroup-specific average treatment effects. However, because the subgroups are only latently associated with the observed variables, the actual individual subgroup memberships are rarely known with certainty in practice and thus have to be imputed. Ignoring the uncertainty in the imputed memberships precludes misclassification errors, potentially leading to biased results and incorrect conclusions. METHODS: We propose a strategy for assessing the sensitivity of inference to classification uncertainty when using such classify-analyze approaches for subgroup effect analyses. We exploit each individual's typically nonzero predictive or posterior subgroup membership probabilities to gauge the stability of the resultant subgroup-specific average causal effects estimates over different, carefully selected subsets of the individuals. Because the membership probabilities are subject to sampling variability, we propose Monte Carlo confidence intervals that explicitly acknowledge the imprecision in the estimated subgroup memberships via perturbations using a parametric bootstrap. The proposal is widely applicable and avoids stringent causal or structural assumptions that existing bias-adjustment or bias-correction methods rely on. RESULTS: Using two different publicly available real-world datasets, we illustrate how the proposed strategy supplements existing latent subgroup effect analyses to shed light on the potential impact of classification uncertainty on inference. First, individuals are partitioned into latent subgroups based on their medical and health history. Then within each fixed latent subgroup, the average treatment effect is assessed using an augmented inverse propensity score weighted estimator. Finally, utilizing the proposed sensitivity analysis reveals different subgroup-specific effects that are mostly insensitive to potential misclassification. CONCLUSIONS: Our proposed sensitivity analysis is straightforward to implement, provides both graphical and numerical summaries, and readily permits assessing the sensitivity of any machine learning-based causal effect estimator to classification uncertainty. We recommend making such sensitivity analyses more routine in latent subgroup effect analyses.

Prescribers' satisfaction with delivering medications for opioid use disorder.

BACKGROUND: Expanding access to medications for opioid use disorder (MOUD), such as buprenorphine and extended release (XR) naltrexone, is critical to addressing the US opioid epidemic, but little is known about prescriber satisfaction with delivering these two types of MOUD. The current study describes the satisfaction of prescribers delivering buprenorphine and XR-naltrexone while examining whether satisfaction is associated with current patient census and organizational environment. METHODS: As part of a cluster randomized clinical trial (RCT) focused on expanding access to medication for opioid use disorder, 41 MOUD prescribers in Florida, Ohio, and Wisconsin completed a web-based survey. The survey included measures of prescriber satisfaction with delivering buprenorphine treatment and XR-naltrexone. In addition, the survey measured several prescriber characteristics and their perceptions of the organizational environment. RESULTS: Prescribers were generally satisfied with their work in delivering these two types of MOUD. Prescribers reporting a greater number of patients (r = .46, p = .006), those who would recommend the center to others (r = .56, p < .001), and those reporting positive relationships with staff (r = .56, p < .001) reported significantly greater overall satisfaction with delivering buprenorphine treatment. Prescribers who more strongly endorsed feeling overburdened reported lower overall buprenorphine satisfaction (r = -.37, p = .02). None of the prescriber characteristics or perceptions of the organizational environment were significantly associated with overall satisfaction with delivering XR-naltrexone treatment. CONCLUSIONS: The generally high levels of satisfaction with both types of MOUD is notable given that prescriber dissatisfaction can lead to turnover and impact intentions to leave the profession. Future research should continue to explore the prescriber characteristics and organizational factors associated with satisfaction in providing different types of MOUD.

Bombesin-Tethered Reactive Oxygen Species (ROS)-Responsive Nanoparticles for Monomethyl Auristatin F (MMAF) Delivery.

Dolastatin derivatives, represented by monomethylauristatin E (MMAE), have been translated in clinic with a form of antibody-drug conjugate; however, their potential in nanoparticle systems has not been well established due to the potential risk of immature release of extremely high cytotoxic dolastatin drugs during blood circulation. Herein, we rationally propose monomethylauristatin F (MMAF), a dolastatin-derived, loaded nanoparticle system composed of bombesin (BBN)-tethered ROS-responsive micelle system (BBN-PEG-PPADT) to achieve efficient anticancer therapy with targeted and efficient delivery of MMAF. The developed MMAF-loaded BBN-PEG-PPADT micelles (MMAF@BBN-PEG-PPADT) exhibited improved cellular uptake via interactions between BBN and gastrin-releasing peptide receptors on the cancer cells and the intracellular burst release of MMAF, owing to the ROS-responsive disruption, which allowed the efficient anticancer effects of MMAF in vitro. This study suggests the potential of nanoparticle systems in the delivery of dolastatin drugs.

Increasing Engagement in Post-Withdrawal Management Services Through a Practice Bundle and Checklist.

Individuals with substance use disorders (SUDs) who engage in post-withdrawal management (or detoxification) continuing care are more likely to remain drug free or sober and less likely to be incarcerated or die of overdose. Yet, just 21-35% of individuals receiving emergency withdrawal management services receive continuing care. This deficiency is occurring, while overdose rates are high, and limited evidence exists on how to improve this vital transition. To address this gap, withdrawal management service providers employed the LINK Care Transition Implementation System to improve withdrawal management to continuing care transition rates. This system integrates three evidence-based implementation science approaches: (a) practice bundle, (b) process checklist, and (c) standardized organizational change model. This integrated implementation approach improved withdrawal management to continuing care transition rates from 20 (baseline average) to 43% (post-intervention) in (n = 6) Wisconsin withdrawal management centers. This study provides insights into how to improve transitions to enhance SUD care and outcomes.

Random Forests Approach for Causal Inference with Clustered Observational Data.

There is a growing interest in using machine learning (ML) methods for causal inference due to their (nearly) automatic and flexible ability to model key quantities such as the propensity score or the outcome model. Unfortunately, most ML methods for causal inference have been studied under single-level settings where all individuals are independent of each other and there is little work in using these methods with clustered or nested data, a common setting in education studies. This paper investigates using one particular ML method based on random forests known as Causal Forests to estimate treatment effects in multilevel observational data. We conduct simulation studies under different types of multilevel data, including two-level, three-level, and cross-classified data. Our simulation study shows that when the ML method is supplemented with estimated propensity scores from multilevel models that account for clustered/hierarchical structure, the modified ML method outperforms preexisting methods in a wide variety of settings. We conclude by estimating the effect of private math lessons in the Trends in International Mathematics and Science Study data, a large-scale educational assessment where students are nested within schools.

NIATx-TI versus typical product training on e-health technology implementation: a clustered randomized controlled trial study protocol.

BACKGROUND: Substance use disorders (SUDs) lead to tens-of-thousands of overdose deaths and other forms of preventable deaths in the USA each year. This results in over $500 billion per year in societal and economic costs as well as a considerable amount of grief for loved ones of affected individuals. Despite these health and societal consequences, only a small percentage of people seek treatment for SUDs, and the majority of those that seek help fail to achieve long-term sobriety. E-health applications in healthcare have proven to be effective at sustaining treatment and reaching patients traditional treatment pathways would have missed. However, e-health adoption and sustainment rates in healthcare are poor, especially in the SUD treatment sector. Implementation engineering can address this gap in the e-health field by augmenting existing implementation models, which explain organizational and individual e-health behaviors retrospectively, with prospective resources that can guide implementation. METHODS: This cluster randomized control trial is designed to test two implementation strategies at adopting an evidence-based mobile e-health technology for SUD treatment. The proposed e-health implementation model is the Network for the Improvement of Addiction Treatment-Technology Implementation (NIATx-TI) Framework. This project, based in Iowa, will compare a control condition (using a typical software product training approach that includes in-person staff training followed by access to on-line support) to software implementation utilizing NIATx-TI, which includes change management training, followed by coaching on how to implement and use the mobile application. While e-health spans many modalities and health disciplines, this project will focus on implementing the Addiction Comprehensive Health Enhancement Support System (A-CHESS), an evidence-based SUD treatment recovery app framework. This trial will be conducted in Iowa at 46 organizational sites within 12 SUD treatment agencies. The control arm consists of 23 individual treatment sites based at five organizations, and the intervention arm consists of 23 individual SUD treatment sites based at seven organizations DISCUSSION: This study addresses an issue of substantial public health significance: enhancing the uptake of the growing inventory of patient-centered evidence-based addiction treatment e-health technologies.

How does art making work? Testing the hypothesized mechanisms of art making on pain experience.

BACKGROUND: Pain is a multidimensional experience that requires a holistic pain management approach. Art making, a holistic, mind-body-spirit approach, has been used as a pain management strategy. Although findings of empirical studies point toward several potential mechanisms through which art making activity may affect the pain experience, these mechanisms have not yet been tested. Therefore, the purpose of this study is to evaluate whether perceived control, self-efficacy, spirituality, and mood mediate the effect of art making activity on pain. MATERIALS AND METHODS: This study is a secondary analysis of cross-sectional survey data collected in 2014 for the Health and Retirement Study (HRS). Data from a national sample of 731 adults, 50 years of age or older were analyzed for the current study. Participants completed a health survey which included measures of art engagement (representing 'effect of art making' in this study), pain severity and interference, and proposed mediating variables (e.g., perceived control, self-efficacy, spirituality and mood). The joint significance test was used to test hypothesized mediation. RESULT: We found that positive mood mediated the effects of art engagement on pain, but perceived control, self-efficacy, spirituality, and negative mood did not. Engagement in art making activity was associated with more positive mood (ß = 0.213, p = .001). In turn, greater positive mood was associated with lower pain severity (ß = -.147, p = .010) and pain interference (ß = -.519, p = .034). CONCLUSION: Results of this study provide preliminary evidence that engagement in art making activity impacts pain experience by enhancing positive mood. A large prospective study examining the hypothesized mediating relationship is necessary to confirm our findings.

Comprehensive Effects of Organized Education for Patients with Chronic Obstructive Pulmonary Disease.

Background: Despite the increasing prevalence of chronic obstructive pulmonary disease (COPD) worldwide, knowledge and awareness of COPD remain extremely low. This prospective study aimed to demonstrate the effectiveness of organized educational intervention. Patients and methods: The study participants included patients diagnosed with COPD and receiving inhaler treatment. In this prospective study, the patients made three sequential visits to the hospital (baseline, 1 month, 3 months). On their first and second visits, patients received systematic education about COPD. On their first and third visits, each patient was evaluated using a COPD Assessment Test, COPD Knowledge Questionnaire, Hospital Anxiety and Depression Scale, and Rosenberg Self-Esteem Scale. Results: Fifty-five participants were enrolled in the study. The mean COPD knowledge score before and after education was 12.51±3.19 and 17.89±1.37, respectively, indicating a significant increase in the score post-education (P<0.001). The measure of patients' inhaler technique also significantly improved after education (5.40±1.50 vs 6.83±0.37 P=0.01). The rate of depression and anxiety after education decreased by 10.9% and 12.7%, respectively (P<0.001). In subgroup analysis, we compared the groups whose knowledge score increased by more than 5 points (Group B) and those whose score did not improve (Group A). In Group B, the mean CAT score significantly improved (2.61±5.88 vs -2.41±7.48, P=0.01), and the duration of their COPD diagnosis before enrollment was significantly shorter (2.72±2.43 vs 5.22±5.11 years, P=0.038) compared to those in Group A. Conclusion: An organized educational program resulted in improved disease-specific knowledge. Disease-specific education is an important part of the treatment of COPD that affects the quality of life and emotional status of patients. Early education after COPD diagnosis can be beneficial.

Physicians' satisfaction with providing buprenorphine treatment.

BACKGROUND: Buprenorphine is a critically important treatment for addressing the opioid epidemic, but there are virtually no studies of physicians' job satisfaction with providing buprenorphine. Physicians' job satisfaction has been linked to burnout and turnover as well as patients' adherence to treatment recommendations, so it is important to understand how physicians' satisfaction with providing buprenorphine treatment compares to their overall job satisfaction. METHODS: As part of a cluster randomized clinical trial (RCT) focused on expanding access to medication for opioid use disorder, 55 physicians working in 38 organizations in Florida, Ohio, and Wisconsin completed a baseline web-based survey. Study measures included global job satisfaction, career satisfaction, and specialty satisfaction. Physicians who were waivered to prescribe buprenorphine were asked to rate their satisfaction with their current buprenorphine practice. RESULTS: Overall, physicians were generally satisfied with their jobs, their careers, and their specialties. When waivered physicians (n = 40) were compared to non-waivered physicians (n = 15) on 13 satisfaction items, there were no statistically significant differences. Among waivered physicians, ratings for buprenorphine work were significantly lower than ratings for general medical practice for finding such work personally rewarding, being pleased with such work, and overall satisfaction. CONCLUSIONS: Although waivered and non-waivered physicians both reported high global job satisfaction, these data suggest that some waivered physicians may view their buprenorphine work as somewhat less satisfying than their global medical practice. Given that job dissatisfaction is a risk factor for turnover and burnout, managers of treatment organizations should consider whether strategies may be able to mitigate some sources of lower satisfaction in the context of buprenorphine treatment.

The payer's role in addressing the opioid epidemic: It's more than money.

BACKGROUND AND OBJECTIVE: County, State, and Federal agencies are addressing the public health opioid crisis. Ohio's 51 county-based Alcohol, Drug Addiction and Mental Health Services (ADAMHS) Boards finance and regulate opioid treatment services within their jurisdictions. This three-year comparative trial collaborated with ADAMHS Boards (n = 14) to test the Advancing Recovery Framework, a suite of organizational and system change strategies designed to promote use of buprenorphine for opioid agonist therapy. METHODS: A multi-level intervention directed payers and treatment agencies to leverage their roles in increasing the use of buprenorphine. Half of the boards partnered with local substance use disorder treatment providers using the partnership strategies recommended by the Advancing Recovery (AR) framework. The comparison boards did not use the partnership strategies. RESULTS AND CONCLUSION: A logistic regression analysis detected increases in the number of patients receiving buprenorphine in both conditions. Buprenorphine use, as a percentage of patients with an opioid use disorder diagnosis, was significantly greater among the boards using the Advancing Recovery strategies during the three-year experimental period (odds ratio (OR) 1.63, 95% CI, 1.50 to 1.76, p < .001) and a one-year maintenance period (OR 2.13, 95% CI, 1.85 to 2.46, p < .001). Boards in both groups provided similar levels of financial support to implement and maintain buprenorphine prescribing. Strategy differences between the study conditions existed in use of a committee that facilitated payer-provider partnering and the ADAMHS boards setting expectations for using buprenorphine. Payer-provider partnerships achieved greater improvements and maximized the effectiveness of funding in increasing access to buprenorphine.

Pharmacotherapy, Resource Needs, and Physician Recruitment Practices in Substance Use Disorder Treatment Programs.

OBJECTIVES: Effective pharmacological treatments for opioid use disorder (OUD) continue to be underutilized, particularly within specialty substance use disorder (SUD) treatment organizations. Few studies have examined whether specific practices to recruit prescribers, financial needs, and human resource needs facilitate or impede the implementation of pharmacotherapy. METHODS: Surveys were completed by administrators from 160 treatment programs in Florida, Ohio, and Wisconsin. Respondents described availability of five pharmacotherapies for treating OUD, organizational resource needs, current use of physician recruitment practices, and buprenorphine treatment slots. RESULTS: The mostly commonly available medications were injectable naltrexone (65.4%; n = 102), buprenorphine-naloxone (55.7%; n = 88), and tablet naltrexone (50.0%; n = 78). Adopters of each of the 5 pharmacotherapies reported significantly greater physician outreach than organizations that did not provide these medications. The mean number of buprenorphine slots was 94.1 (SD 205.9). There were unique correlates of adoption (ie, any slots) and availability (number of slots) of buprenorphine. Physician outreach activities were correlated with the likelihood of nonadoption, whereas medical resource needs (ie, needing more physicians to prescribe pharmacotherapy) and dedicated resources for physician recruitment were associated with the number of slots. CONCLUSIONS: Physician recruitment activities differentiated those organizations that had existing pharmacotherapy treatment capacity (ie, any slots) from those that had no capacity. Efforts to address the medical resource needs of treatment organizations, and also strategies that encourage organizations to devote resources to recruiting prescribers may hold promise for increasing access to these lifesaving treatments.

Low-power and low-drug-dose photodynamic chemotherapy via the breakdown of tumor-targeted micelles by reactive oxygen species.

Tumor-targeted delivery of anticancer agents using nanocarriers has been explored to increase the therapeutic index of cancer chemotherapy. However, only a few nanocarriers are clinically available because the physiological complexity often compromises their ability to target, penetrate, and control the release of drugs. Here, we report a method which dramatically increases in vivo therapeutic drug efficacy levels through the photodynamic degradation of tumor-targeted nanocarriers. Folate-decorated poly(ethylene glycol)-polythioketal micelles are prepared to encapsulate paclitaxel and porphyrins. Photo-excitation generates reactive oxygen species within the micelles to cleave the polythioketal backbone efficiently and facilitate drug release only at the illuminated tumor site. Intravenous injection of a murine xenograft model with a low dose of paclitaxel within the micelles, one-milligram drug per kg (mouse), corresponding to an amount less than that of Taxol by one order of magnitude, induces dramatic tumor regression without any acute systemic inflammation responses or organ toxicity under low-power irradiation (55 mW cm-2) at 650 nm.

Minimal change disease related to rifampicin presenting with acute renal failure during treatment for latent tuberculosis infection: A case report.

RATIONALE: The standard drugs used to treat tuberculosis are rifampicin and isoniazid. These agents are usually safe and inexpensive for short-term use in treatment of latent tuberculosis infection, but sometimes cause adverse renal effects, including minimal change disease (MCD). PATIENT CONCERNS: Here, we report a 51-year-old woman with latent tuberculosis infection who developed nephrotic syndrome during treatment with rifampicin and isoniazid for 25 days. DIAGNOSES: Renal biopsy findings were compatible with MCD, and she had no relevant medical history and was not taking other medications. A diagnosis of anti-tuberculosis drug- induced MCD was made. This is the first report of acute renal failure due to rifampicin and/or isoniazid-induced MCD. INTERVENTIONS: After cessation of rifampicin and isoniazid, however, acute renal failure progressed and she was treated with temporary dialysis and oral prednisolone. OUTCOMES: The patient achieved complete remission after cessation of rifampicin and isoniazid with steroid therapy. LESSONS: This case demonstrates that rifampicin and/or isoniazid can cause nephrotic syndrome with acute renal failure during the first months of continuous latent tuberculosis therapy. Therefore, renal function and proteinuria should be monitored carefully in all patients taking rifampicin and isoniazid, especially during the first few months of therapy.

Payer Policy Behavior Towards Opioid Pharmacotherapy Treatment in Ohio.

OBJECTIVE: Few studies examine how payers address the need for improved access to pharmacotherapy for opioid use disorders and the influence of environmental variables on access to opioid agonist and antagonist medications. METHOD: The 52 Ohio Addiction Drug Abuse and Mental Health Services (ADAMHS) Boards that disburse funds for treatment services for the uninsured and underinsured were surveyed to assess coverage for opioid agonist and antagonist treatment medications. Analyses examined public health data on regional opioid addiction patterns, characteristics of the local health insurance market, and their associations with coverage for opioid addiction pharmacotherapy. RESULTS: Most (70%) of the 44 participating ADAMHS Boards paid for opioid treatment medications. For payment policy, all Boards required behavioral therapy to be provided in conjunction with opioid agonist or opioid antagonist therapy, and 27% of the Boards limited length of a buprenorphine therapy regimen. Higher local opioid treatment admission rates were associated with higher rates of Board funding for opioid treatment pharmacotherapy. Environmental variables (eg, overdose fatality rates or the behaviors of private insurance payers) were not associated with ADAMHS support for opioid agonist or antagonist medication. CONCLUSIONS: The analysis highlights the policy preferences of these payers. Follow-up studies should examine the payer decision-making processes, preferences, and attitudes that affect support for pharmacotherapy for opioid dependence.

A first case report of pulmonary hyalinizing granuloma associated with immunoglobulin A nephropathy.

RATIONALE: Pulmonary hyalinizing granuloma (PHG) is a rare benign disease that has been shown to be associated with the deposition of immune complexes in the lung parenchyma caused by infection or autoimmune diseases. There have been no reports of PHG in association with immunoglobulin A nephropathy (IgAN). PATIENT CONCERNS: A 30-year-old woman visited with a 12-month history of dyspnea on exertion and cough that had worsened 1 month before her visit. DIAGNOSIS: PHG associated with IgAN. INTERVENTIONS: Steroid pulse therapy was performed. OUTCOMES: The patient was discharged uneventfully. LESSONS: We present a case of PHG presenting as multiple pulmonary nodules mimicking metastatic lung cancer, which was diagnosed using wedge resection of the right middle lobe through video-assisted thoracoscopic surgery.

Engineered Zn(II)-Dipicolylamine-Gold Nanorod Provides Effective Prostate Cancer Treatment by Combining siRNA Delivery and Photothermal Therapy.

Combination cancer treatment has emerged as a critical approach to achieve remarkable anticancer effect. In this study, we prepared a theranostic nanoformulation that allows for photoacoustic imaging as well as combination gene and photothermal therapy. Gold nanorods (GNR) were coated with dipicolyl amine (DPA), which forms stable complexes with Zn2+ cations. The resulting nanoparticles, Zn(II)/DPA-GNR, recognize phosphate-containing molecules, including siRNA, because of the specific interaction between Zn(II) and the phosphates. We chose anti-polo-like kinase 1 siRNA (siPLK) as our example for gene silencing. The strong complexation between Zn(II)/DPA-GNR and siPLK provided high stability to the nano-complexes, which efficiently delivered siRNA into the targeted cancer cells in vitro and in vivo. The particle served as a theranostic agent because the GNRs of nano-complexes permitted effective photothermal therapy as well as photoacoustic imaging upon laser irradiation. This gene/photothermal combination therapy using siPLK/Zn(II)DPA-GNRs exhibited significant antitumor activity in a PC-3 tumor mouse model. The concept described in this work may be extended to the development of efficient delivery strategies for other polynucleotides as well as advanced anticancer therapy.
