RESUMO

Abstract Earias vittellaFabricius, 1794 (Noctuidae: Lepidoptera) is deliberated to be one of the most destructive pests of cotton and okra vegetation in the world including Asia. The pest has established resistance to various synthetic insecticides. The use of bio-pesticide is one of the unconventional approaches to develop a vigorous ecosystem without harming non- target pests and beneficial natural insect fauna. In the present study, the toxicity levels of Citrullus colocynthis seed extract have been evaluated against the populations of E. vittellaunder standardized laboratory conditions. The toxic effects of C. colocynthis on development periods, protein contents and esterase activity of the life stages of E. vittella were also evaluated. The toxicity levels of methanol, ethanol, hexane, water and profenofos were evaluated on the 1st instar larvae of E. vittella. LC30 and LC80 concentrations exhibited the effectiveness of methanol-based C. colocynthis seed extract against 1st instar larvae of E. vitella. The enhanced larval and pupal periods were revealed in treated samples during the comparison with untreated samples. The intrinsic rate of increase, net reproductive rate in the LC30 and LC80 concentrations exposed larvae remained less than the control treatment. Fecundity, the esterase activity and protein contents were declined in LC30 and LC80 treated samples as compared to the control. The present findings suggest that C. colosynthis extracts based botanical insecticides are beneficial, ecosystem sustainable and can be integrated with insect management programs from environment safety perspective.


Resumo Earias vittella Fabricius, 1794 (Noctuidae: Lepidoptera) é considerada uma das pragas mais destrutivas de algodão e quiabo no mundo, incluindo a Ásia. Essa praga estabeleceu resistência a vários inseticidas sintéticos. O uso de biopesticidas é uma das abordagens não convencionais para desenvolver um ecossistema saudável sem prejudicar as pragas não alvo e a fauna natural benéfica de insetos. No presente estudo, os níveis de toxicidade do extrato de semente de Citrullus colocynthis foram avaliados nas populações de E. vittella em condições de laboratório padronizadas. Os efeitos tóxicos de C. colocynthis nos períodos de desenvolvimento, conteúdo de proteína e atividade esterase das fases de vida de E. vittella também foram avaliados. Os níveis de toxicidade de metanol, etanol, hexano, água e profenofós foram avaliados em larvas de 1º instar de E. vittella. As concentrações de LC30 e LC80 apresentaram eficácia do extrato de sementes de C. colocynthis à base de metanol contra larvas de 1º instar de E. vittella. Os períodos larval e pupal aumentados foram revelados nas amostras tratadas durante a comparação com as amostras não tratadas. A taxa intrínseca de aumento e a taxa reprodutiva líquida nas concentrações de larvas expostas LC30 e LC80 permaneceram menores do que o tratamento controle. A fecundidade, a atividade da esterase e o conteúdo de proteína diminuíram nas amostras tratadas com LC30 e LC80 em comparação com o controle. As presentes descobertas sugerem que os extratos de C. colocynthis à base de inseticidas botânicos são benéficos, sustentáveis para o ecossistema e podem ser integrados com programas de manejo de insetos do ponto de vista da segurança ambiental.

RESUMO

PURPOSE: We investigated the prevalence of financial toxicity in a population undergoing hematopoietic cell transplantation (HCT) evaluation and measured its impact on post-transplant clinical and health-related quality-of-life outcomes. MATERIALS AND METHODS: This was a prospective study in patients undergoing evaluation for allogeneic HCT between January 1, 2018, and September 23, 2020, at a large academic medical center. Financial health was measured via a baseline survey and the comprehensive score for financial toxicity-functional assessment of chronic illness therapy (COST-FACIT) survey. The cohort was divided into three groups: none (grade 0), mild (grade 1), and moderate-high financial toxicity (grades 2-3). Health-related quality of life outcomes were measured at multiple time points. Multivariate logistic regression analysis evaluated factors associated with financial toxicity. Kaplan-Meier curves and log-rank tests was used to evaluate overall survival (OS) and nonrelapse survival. RESULTS: Of 245 patients evaluated for transplant, 176 (71.8%) completed both questionnaires (median age was 57 years, 63.1% were male, 72.2% were White, and 39.2% had myelodysplastic syndrome, 38.1% leukemia, and 13.6% lymphoma). At initial evaluation, 83 (47.2%) patients reported no financial toxicity, 51 (29.0%) with mild, and 42 (23.9%) with moderate-high financial toxicity. Patients with financial toxicity reported significant cost-cutting behaviors, including reduced spending on food or clothing, using their savings, or not filling a prescription because of costs (P < .0001). Quality of life was lower in patients with moderate-high financial toxicity at 6 months (P = .0007) and 1 year (P = .0075) after transplant. Older age (>62; odds ratio [OR], 0.33 [95% CI, 0.13 to 0.79]; P = .04) and income ≥$60,000 in US dollars (USD) (OR, 0.17 [95% CI, 0.08 to 0.38]; P < .0001) were associated with lower odds of financial toxicity. No association was noted between financial toxicity and selection for transplant, OS, or nonrelapse mortality. CONCLUSION: Financial toxicity was highly correlated with patient-reported changes in compensatory behavior, with notable impact on patient quality of life after transplant.

RESUMO

Purpose: To investigate the relationship between limited English proficiency (LEP) and diabetic retinopathy (DR) in patients presenting for cataract surgery. Methods: This is a retrospective observational study of patients who underwent cataract surgery between January 2014 and February 2020. Patients who self-identified as needing or preferring an interpreter were defined as having LEP. Differences in demographics, characteristics, and outcomes including history of type 2 diabetes (T2DM), DR, preoperative best corrected visual acuity (BCVA), macular edema, and anti-vascular endothelial growth factor injections were analyzed. Statistical comparisons were assessed using logistic regression with generalized estimating equations. Results: We included 13,590 eyes. Of these, 868 (6.4%) were from LEP patients. Patients with LEP were more likely to be Hispanic (P < 0.001), female sex (P = 0.008), or older age (P = 0.003) and have worse mean BCVA at presentation (P < 0.001). Patients with LEP had a significantly higher rate of T2DM (P < 0.001), macular edema (P = 0.033), and DR (18.1% vs. 5.8%, P < 0.001). Findings remained significant when controlling for age, sex, race/ethnicity, and type of health insurance. Patients with LEP and DR were more likely to have had later stages of DR (P = 0.023). Conclusions: Patients with LEP presenting for cataract surgery had a higher rate of DR and associated complications compared to patients with English proficiency. Further studies are needed to understand how language disparities influence health and what measures could be taken to improve healthcare in this vulnerable population. Translational Relevance: Our study highlights healthcare disparities within ophthalmology and emphasizes the importance of advocating for improved healthcare delivery for patients with LEP.

RESUMO

PURPOSE: To determine differences in cataract surgery outcomes between English proficient (EP) and limited English proficiency (LEP) patients. SETTING: Sue Anschutz-Rodgers Eye Center, Aurora, Colorado. DESIGN: Retrospective. METHODS: Patients who underwent phacoemulsification at the Sue Anschutz-Rogers Eye Center between January 2014 and February 2020 were included. Patients who self-identified as needing or preferring an interpreter in medical encounters were defined as LEP. Differences in surgical characteristics and outcomes including cataract maturity, surgical complexity, and surgical complications were analyzed. RESULTS: 868 eyes (6.4%) were identified from LEP patients. LEP patients were more likely to have mature cataracts (5.1% vs 2.3%, P < .0001). LEP patients' surgeries were more likely to be considered complex (27.8% vs 15.3%, P < .0001) and use higher cumulative dissipated energy (mean of 9.5 [SD = 9.5] vs 7.2 [SD = 7.1], P < .0001). Preoperative visual acuity was worse in LEP patients (logMAR 0.566 [SD = 0.64] vs 0.366 [SD = 0.51], P < .0001) but showed greater improvement after surgery (logMAR 0.366 [SD = 0.54] vs 0.254 [SD = 0.41], P < .0001). There were no significant differences in operative time, intraoperative or postoperative complications. More LEP patients were on steroids 4 weeks postoperatively when compared with EP patients (14.6% vs 10.1%, P < .0002). LEP patients were less likely to undergo subsequent YAG capsulotomy (7.3% vs 12.8%, P < .0001). CONCLUSIONS: Disparities in cataract outcomes between EP and LEP patients was demonstrated. Further research into ophthalmic health disparities for LEP patients is needed to understand the root causes and how they can be addressed.

RESUMO

INTRODUCTION: We sought to examine patient and provider perspectives regarding modifiable contributors to breast cancer treatment and to assess perceptual alignment between these two groups. MATERIALS: Participants were women≥18 y with stage 0-IV breast cancer who received all oncologic care in a single health system and physicians and advanced practice providers who provided medical, radiation, or surgical oncology care for breast cancer. All completed ∼45-min semistructured interviews that were recorded and transcribed verbatim. A 5-stage approach to thematic analysis was conducted, with emergent themes and exemplar quotes placed into clinical, psychological, social/logistical, financial, and lifestyle categories using a multilevel conceptual framework. RESULTS: Eighteen patients (9 Black, 9 White, and median age 60 y) and 10 providers (6 physicians and 4 advanced practice providers) were interviewed from May to November 2018. Both patients and providers perceived suboptimal communication, parking and transportation, and competing family-caregiving responsibilities as modifiable barriers to care. Treatment costs were cited by patients as barriers that were inadequately addressed even with referrals to financial counselors, but providers did not raise the issue of cost unless prompted by patients and did not feel prepared to discuss the topic when it arose. Providers cited obesity as a barrier to treatment, a view not shared by patients. CONCLUSIONS: Several modifiable factors were recognized by both patients and providers as either promoting or detracting from treatment receipt, but there was also significant incongruence and asymmetry. Alignment of provider and patient perceptions regarding contributors to guideline-concordant care receipt could mitigate disparities in breast cancer treatment and outcomes.

RESUMO

BACKGROUND: We sought to identify modifiable factors associated with cancer screening in a community-based health assessment. METHODS: 24 organizations at 47 community events in central North Carolina distributed a 91-item survey from April-December 2017. Responses about (1) interest in disease prevention, (2) lifestyle choices (e.g., diet, tobacco), and (3) perceptions of primary care access/quality were abstracted to examine their association with self-reported screening participation and knowledge about breast, prostate, and colorectal cancer. RESULTS: 2135/2315 participants (92%; 38.5% White, 38% Black, 9.9% Asian) completed screening questions. >70% of screen-eligible respondents reported guideline-concordant screening. Healthy dietary habits were associated with greater knowledge about breast and colorectal cancer screening; reporting negative attitudes about and barriers to healthcare were associated with less breast, prostate, and colorectal cancer screening. Having a place to seek medical care (a proxy for primary care access) was independently associated with being ∼5 times as likely to undergo colorectal screening (OR 4.66, 95% CI 1.58-13.79, all p < 0.05). CONCLUSIONS: In this diverse, community-based sample, modifiable factors were associated with screening engagement, highlighting opportunities for behavioral intervention.

RESUMO

Thimerosal is an organomercurial compound, which is used in the preparation of intramuscular immunoglobulin, antivenoms, tattoo inks, skin test antigens, nasal products, ophthalmic drops, and vaccines as a preservative. In most of animal species and humans, the kidney is one of the main sites for mercurial compounds deposition and target organs for toxicity. So, the current research was intended to assess the thimerosal induced nephrotoxicity in male rats. Twenty-four adult male albino rats were categorized into four groups. The first group was a control group. Rats of Group-II, Group-III, and Group-IV were administered with 0.5µg/kg, 10µg/kg, and 50µg/kg of thimerosal once a day, respectively. Thimerosal administration significantly decreased the activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), glutathione reductase (GR), glutathione (GSH), and protein content while increased the thiobarbituric acid reactive substances (TBARS) and hydrogen peroxide (H2O2) levels dose-dependently. Blood urea nitrogen (BUN), creatinine, urobilinogen, urinary proteins, kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) levels were substantially increased. In contrast, urinary albumin and creatinine clearance was reduced dose-dependently in thimerosal treated groups. The results demonstrated that thimerosal significantly increased the inflammation indicators including nuclear factor kappaB (NF-κB), tumor necrosis factor-α (TNF-α), Interleukin-1β (IL-1β), Interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activities, DNA and histopathological damages dose-dependently. So, the present findings ascertained that thimerosal exerted nephrotoxicity in male albino rats.

Na maioria das espécies animais e nos humanos, o rim é um dos principais locais de deposição de compostos de mercúrio e órgãos-alvo de toxicidade. Assim, a presente pesquisa teve como objetivo avaliar a nefrotoxicidade induzida pelo timerosal em ratos machos. Vinte e quatro ratos albinos machos adultos foram categorizados em quatro grupos. O primeiro grupo era um grupo de controle. Ratos do Grupo II, Grupo III e Grupo IV receberam 0,5µg / kg, 10µg / kg e 50µg / kg de timerosal uma vez ao dia, respectivamente. A administração de timerosal diminuiu significativamente as atividades de catalase (CAT), superóxido dismutase (SOD), peroxidase (POD), glutationa redutase (GR), glutationa (GSH) e conteúdo de proteína, enquanto aumentou as substâncias reativas ao ácido tiobarbitúrico (TBARS) e peróxido de hidrogênio (H2O2) níveis dependentes da dose. Os níveis de nitrogênio ureico no sangue (BUN), creatinina, urobilinogênio, proteínas urinárias, molécula de lesão renal-1 (KIM-1) e lipocalina associada à gelatinase de neutrófilos (NGAL) aumentaram substancialmente. Em contraste, a albumina urinária e a depuração da creatinina foram reduzidas de forma dependente da dose nos grupos tratados com timerosal. Os resultados demonstraram que o timerosal aumentou significativamente os indicadores de inflamação, incluindo fator nuclear kappaB (NF-κB), fator de necrose tumoral-α (TNF-α), interleucina-1β (IL-1β), níveis de interleucina-6 (IL-6) e atividades da ciclooxigenase-2 (COX-2), DNA e danos histopatológicos dependentes da dose. Portanto, os presentes achados verificaram que o timerosal exerceu nefrotoxicidade em ratos albinos machos.

RESUMO

BACKGROUND: For patients and their intimate partners, advanced cancer poses significant challenges that can negatively impact both individuals and their relationship. Prior studies have found evidence that couple-based communication skills interventions can to be beneficial for patients and partners. However, these studies have been limited by reliance on in-person treatment delivery and have not targeted couples at high risk for poor outcomes. This study tests the efficacy of a Couples Communication Skills Training (CCST) intervention delivered via videoconference for couples reporting high levels of holding back from discussing cancer-related concerns, a variable associated with poorer psychological and relationship functioning. METHODS: This RCT is designed to evaluate the efficacy of CCST in improving patient and partner relationship functioning (primary outcome). Secondary outcomes include patient and partner psychological functioning and patient symptoms and health care use. We also examine the role of objective and self-reported communication behaviors as mediators of treatment effects. Two hundred thirty patients with advanced lung, gastrointestinal, genitourinary, and breast cancer and their partners will be randomized to CCST or an education control intervention. Participants in both conditions complete self-reported outcome measures at baseline, mid-treatment, post-treatment, and 3 months post-treatment. Objective measures of communication are derived from video-recorded couple conversations collected at baseline and post-treatment. An implementation-related process evaluation (assessing implementation outcomes and potential barriers to/facilitators of implementation) will be conducted to inform future efforts to implement CCST in real-world settings. DISCUSSION: This trial can yield important new knowledge about effective ways to improve patient and partner adjustment to advanced cancer. TRIAL REGISTRATION: This study trial is registered at clinicaltrials.gov (Trial # NCT04590885); registration date: October 19, 2020.

RESUMO

Importance: High-deductible health plans (HDHPs) require high upfront cost-sharing, which has been associated with suboptimal anticancer medication uptake and adherence. Whether HDHP enrollment has limited the affordability and use of lenalidomide therapy among commercially insured patients with multiple myeloma is unknown. Objective: To assess the association of HDHP enrollment with out-of-pocket spending on and adherence to lenalidomide therapy. Design, Setting, and Participants: In this cohort study, data were obtained from the IBM MarketScan Commercial Claims and Encounters Database for adults aged 18 to 64 years with multiple myeloma who newly initiated lenalidomide therapy between April 1, 2013, and June 30, 2017. Quantile regression and modified Poisson regression evaluated out-of-pocket spending, and group-based trajectory models and multinomial logistic regression examined patterns of and factors associated with adherence. Analyses were conducted from April to August 2020. Exposures: High-deductible health plan enrollment in the 3 months before and 6 months after initiation of lenalidomide therapy. Main Outcomes and Measures: Distribution of out-of-pocket spending, the probability of paying more than $100 for the first and any lenalidomide prescription fill, and monthly lenalidomide therapy adherence using the proportion of days covered (≥80%). Results: Of the 3163 commercially insured patients who initiated lenalidomide therapy (median age, 57 years [IQR, 53-60 years for HDHP enrollees and 52-61 years for non-HDHP enrollees]), 328 (10.4%) were enrolled in HDHPs and 1769 (55.9%) were women. Among the highest spenders (95th percentile), HDHP enrollees paid $376 (95% CI, -$28 to $780) and $217 (95% CI, $106-$323) more for their first and any lenalidomide prescription fill, respectively, compared with non-HDHP enrollees in the 6 months after initiation. High-deductible health plan enrollment was also associated with an increased risk of paying more than $100 for the initial (adjusted risk ratio [aRR], 1.30 [95% CI, 1.13-1.50]) and any (aRR, 1.26 [95% CI, 1.12-1.42]) lenalidomide prescription fill. Three adherence trajectory groups were identified: those with high adherence (n = 1273), late nonadherence (n = 1084), and early nonadherence (n = 805). High-deductible health plan enrollment was not associated with adherence group assignment. Conclusions and Relevance: In this cohort study, HDHP enrollment was associated with higher out-of-pocket spending per lenalidomide prescription fill; however, no statistically significant differences in adherence patterns between HDHP and non-HDHP enrollees were observed. Patient (eg, perceptions of treatment benefits), payer (eg, out-of-pocket maximums), and clinician (eg, counseling patients on disease severity) factors may have limited the potential for nonadherence among commercially insured patients who initiated lenalidomide therapy.

RESUMO

PURPOSE: Mobile health interventions can improve patient care. We developed the Digital Supportive Care Awareness and Navigation (D-SCAN) application (app) to facilitate symptom monitoring and use/awareness of cancer supportive care resources. This study tested feasibility, usability/satisfaction, and preliminary efficacy of D-SCAN. METHODS: We randomized 50 patients with advanced cancer to receive the D-SCAN intervention or usual care; 10 caregivers also received D-SCAN. The primary feasibility outcome was determined by weekly symptom survey completion and end of study procedures. We assessed secondary outcomes including usability/satisfaction, awareness/use of supportive care resources, patient activation, and quality of life via various questionnaires including the Net Promoter Score (NPS), Patient Activation Measure (PAM-13), Functional Assessment of Cancer Therapy-General (FACT-G), and Caregiver Oncology Quality of Life (CarGOQOL) questionnaire. RESULTS: Seventy-six percent of intervention patients met feasibility criteria, exceeding our pre-determined threshold of 75%. Usability/satisfaction by NPS was high, at 14.3% and 12.5% for patients and caregivers, respectively. Intervention patient and caregiver resource awareness increased by a mean of 3.7 (p = 0.27) and 4.1 items, respectively. Supportive care resource utilization increased by a mean of 0.8 items for intervention patients (p = 0.70) and 0.6 for caregivers. PAM-13 increased by a mean of 1.6 for intervention patients (p = 0.65). FACT-G increased by a mean of 1.1 for intervention patients (p = 0.91), and CarGOQoL increased by a mean of 2.2 (p = 0.41). CONCLUSION: D-SCAN is a feasible, usable, and satisfactory intervention for augmenting patient and caregiver supportive care. Further testing is necessary to formally assess D-SCAN's efficacy and impact on patients and caregivers. CLINICAL TRIAL REGISTRATION NUMBER: NCT03628794. Registered on August 14th, 2018.

RESUMO

OBJECTIVES: Clinicians increasingly believe they should discuss costs with their patients. We aimed to learn what strategies clinicians, clinic leaders, and health systems can use to facilitate vital cost-of-care conversations. METHODS: We conducted focus groups and semi-structured interviews with outpatient clinicians at two US academic medical centers. Clinicians recalled previous cost conversations and described strategies that they, their clinic, or their health system could use to facilitate cost conversations. Independent coders recorded, transcribed, and coded focus groups and interviews. RESULTS: Twenty-six clinicians participated between December 2019 and July 2020: general internists (23%), neurologists (27%), oncologists (15%), and rheumatologists (35%). Clinicians proposed the following strategies: teach clinicians to initiate cost conversations; systematically collect financial distress information; partner with patients to identify costs; provide accurate insurance coverage and/or out-of-pocket cost information via the electronic health record; develop local lists of lowest-cost pharmacies, laboratories, and subspecialists; hire financial counselors; and reduce indirect costs (e.g., parking). CONCLUSIONS: Despite considerable barriers to discussing, identifying, and reducing patient costs, clinicians described a variety of strategies for improving cost communication in the clinic. PRACTICE IMPLICATIONS: Health systems and clinic leadership can and should implement these strategies to improve the financial health of the patients they serve.

RESUMO

Castleman Disease (CD) is a rare entity that typically presents as an enhancing nodal mass in the mediastinum or head and neck region on computed tomography (CT). It may manifest as unicentric or multicentric regions of lymph node enlargement. A key clinical issue in the context of CD is delayed diagnosis, which contributes adversely to patient outcome, given that accurate diagnosis facilitates earlier treatment of this curable disease. This article will address relevant imaging aspects, with reference to typical and atypical imaging features of CD, illustrated using examples from our specialist centre; the imaging journey for patients with CD; and will provide practical pointers to radiologists in differentiating CD from other benign and malignant causes of enhancing lymphadenopathy, including lymphoma and neoplastic adenopathy. We will also review current classification tools and staging challenges with reference to World Health Organization guidelines, International Working Group guidelines as well as the Lugano classification. Finally, we will discuss the potential role of additional imaging techniques in CD, highlighting novel imaging methods and expanded utilities from our specialist centre.

RESUMO

Rising costs of cancer care drive patient financial toxicity (FT) that perpetuates known health disparities in access and quality cancer treatment. This Review discusses how FT is a barrier to cancer research and treatment, and discusses potential solutions to improve affordability and reduce healthcare disparities for our patients.

RESUMO

Plant growth and productivity is restricted by a multitude of abiotic stresses. These stresses negatively affect physiological and metabolic pathways, leading to the production of many harmful substances like ROS, lipid peroxides and aldehydes. This study was conducted to investigate the role of Arabidopsis ALDH3I1 gene in multiple abiotic stress tolerance. Transgenic tobacco plants were generated that overexpress the ALDH3I1 gene driven by the CaMV35S promoter and evaluated under different abiotic stresses, namely salt, drought, cold and oxidative stress. Tolerance to stress was evaluated based on responses of various growth and physiological traits under stress condition. Transgenic plants displayed elevated ALDH3I1 transcript levels compared to WT plants. The constitutive ectopic expression of ALDH3I1 conferred increased tolerance to salt, drought, cold and oxidative stresses in transgenic plants, along with improved plant growth. Transgenic plants overexpressing ALDH3I1 had higher chlorophyll content, photosynthesis rate and proline, and less accumulation of ROS and malondialdehyde compared to the WT, which contributed to stress tolerance in transgenic plants. Our results further revealed that ALDH3I1 had a positive effect on CO2 assimilation rate in plants under abiotic stress conditions. Overall, this study revealed that ALDH3I1 positively regulates abiotic stress tolerance in plants, and has future implications in producing transgenic cereal and horticultural plants tolerant to abiotic stresses.

RESUMO

BACKGROUND: As treatments for cancer have improved, more people are surviving cancer. However, compared to people without a history of cancer, cancer survivors are more likely to die of cardiovascular disease (CVD). Increased risk for CVD-related mortality among cancer survivors is partially due to lack of medication adherence and problems that exist in care coordination between cancer specialists, primary care physicians, and cardiologists. METHODS/DESIGN: The Onco-primary care networking to support TEAM-based care (ONE TEAM) study is an 18-month cluster-randomized controlled trial with clustering at the primary care clinic level. ONE TEAM compares the provision of the iGuide intervention to patients and primary care providers versus an education-only control. For phase 1, at the patient level, the intervention includes video vignettes and a live webinar; provider-level interventions include electronic health records-based communication and case-based webinars. Participants will be enrolled from across North Carolina one of their first visits with a cancer specialist (e.g., surgeon, radiation or medical oncologist). We use a sequential multiple assignment randomized trial (SMART) design. Outcomes (measured at the patient level) will include Healthcare Effectiveness Data and Information Set (HEDIS) quality measures of management of three CVD comorbidities using laboratory testing (glycated hemoglobin [A1c], lipid profile) and blood pressure measurements; (2) medication adherence assessed pharmacy refill data using Proportion of Days Covered (PDC); and (3) patient-provider communication (Patient-Centered Communication in Cancer Care, PCC-Ca-36). Primary care clinics in the intervention arm will be considered non-responders if 90% or more of their participating patients do not meet the modified HEDIS quality metrics at the 6-month measurement, assessed once the first enrollee from each practice reaches the 12-month mark. Non-responders will be re-randomized to either continue to receive the iGuide 1 intervention, or to receive the iGuide 2 intervention, which includes tailored videos for participants and specialist consults with primary care providers. DISCUSSION: As the population of cancer survivors grows, ONE TEAM will contribute to closing the CVD outcomes gap among cancer survivors by optimizing and integrating cancer care and primary care teams. ONE TEAM is designed so that it will be possible for others to emulate and implement at scale. TRIAL REGISTRATION: This study (NCT04258813) was registered in clinicaltrals.gov on February 6, 2020.

RESUMO

Thimerosal is an organomercurial compound, which is used in the preparation of intramuscular immunoglobulin, antivenoms, tattoo inks, skin test antigens, nasal products, ophthalmic drops, and vaccines as a preservative. In most of animal species and humans, the kidney is one of the main sites for mercurial compounds deposition and target organs for toxicity. So, the current research was intended to assess the thimerosal induced nephrotoxicity in male rats. Twenty-four adult male albino rats were categorized into four groups. The first group was a control group. Rats of Group-II, Group-III, and Group-IV were administered with 0.5µg/kg, 10µg/kg, and 50µg/kg of thimerosal once a day, respectively. Thimerosal administration significantly decreased the activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), glutathione reductase (GR), glutathione (GSH), and protein content while increased the thiobarbituric acid reactive substances (TBARS) and hydrogen peroxide (H2O2) levels dose-dependently. Blood urea nitrogen (BUN), creatinine, urobilinogen, urinary proteins, kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) levels were substantially increased. In contrast, urinary albumin and creatinine clearance was reduced dose-dependently in thimerosal treated groups. The results demonstrated that thimerosal significantly increased the inflammation indicators including nuclear factor kappaB (NF-κB), tumor necrosis factor-α (TNF-α), Interleukin-1ß (IL-1ß), Interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activities, DNA and histopathological damages dose-dependently. So, the present findings ascertained that thimerosal exerted nephrotoxicity in male albino rats.
