RESUMEN

OBJECTIVE: To create a novel screening tool that identified patients who were most likely to benefit from pharmacist in-home medication reviews. DESIGN: Single-center, retrospective study. SETTING AND PARTICIPANTS: A total of 25 homebound patients in Forsyth County, NC, aged 60 years or older with physical or cognitive impairments and enrolled in home-based primary care or transitional and supportive care programs participated in the study. Pharmacy resident-provider pairs conducted home visits for all patients in the study. Pharmacy residents assessed the subjective risk (high, medium, low) of medication nonadherence using information obtained from home visits (health literacy, support network, medications, and detection of something unexpected related to medications). An electronic medical record-based risk score was simultaneously calculated using screening tool components (i.e., electronic frailty index score, LACE+ index [length of stay in the hospital, acuity of admission, comorbidity, emergency department utilization in the 6 months before admission], and 2015 American Geriatric Society Beers Criteria). OUTCOME MEASURES: The electronic medical record-based screening tool numerical risk scores were compared with pharmacy resident subjective risk assessments using tree-based classification models to determine screening tool components that best predicted pharmacy residents' subjective assessment of patients' likelihood of benefit from in-home pharmacist medication review. Following the study, satisfaction surveys were given to providers and pharmacy residents. RESULTS: The best predictor of high-risk patients was an electronic frailty index score greater than 0.32 (indicating very frail) or LACE+ index greater than or equal to 59 (at high risk for hospital readmission). Pharmacy residents and providers agreed that homebound patients at high-risk for medication noncompliance benefited from pharmacist time and attention in home visits. CONCLUSION: In homebound older persons, this screening tool allowed for the identification of patients at high-risk for medication nonadherence through targeted in-home pharmacist medication reviews. Further studies are needed to validate the accuracy of this tool internally and externally.

RESUMEN

The authors evaluated the feasibility of a 1-hour session to ensure competency in gait and falls risk assessment for medical students at their institution. The session included a history and exam with faculty and staff as standardized patients, gait recognition videos, and case evaluation for falls risk assessment and prevention. Student perceptions were evaluated using a retrospective pre-post survey, scored on a 5-point Likert-type scale. Wilcoxon signed-rank tests were used to assess change and Kruskal-Wallis tests were used to analyze differences by residency choice. A range of five to 11 faculty and staff certified 238 medical students during eight 1-hour sessions. Overall self-perception of competence in falls risk assessment and prevention improved (p ≤ .001), and did not differ by residency choice, both before and after the training program (p = .73 and p = .25). Feedback was positive. This session is a feasible way to teach and assess the competency for falls risk assessment with modest time commitment.

RESUMEN

PURPOSE: To report additional ocular outcomes of intensive treatment of hyperglycemia, blood pressure, and dyslipidemia in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. DESIGN: Double 2×2 factorial, multicenter, randomized clinical trials in people with type 2 diabetes who had cardiovascular disease or cardiovascular risk factors. In the glycemia trial, targets of intensive and standard treatment were: hemoglobin A1c <6.0% and 7.0% to 7.9%, respectively, and in the blood pressure trial: systolic blood pressures of <120 and <140 mmHg, respectively. The dyslipidemia trial compared fenofibrate plus simvastatin with placebo plus simvastatin. PARTICIPANTS: Of the 3472 ACCORD Eye Study participants enrolled, 2856 had 4-year data (85% of survivors). METHODS: Eye examinations and fundus photographs were taken at baseline and year 4. Photographs were graded centrally for retinopathy severity and macular edema using the Early Treatment Diabetic Retinopathy Study (ETDRS) methods. MAIN OUTCOME MEASURES: Three or more steps of progression on the ETDRS person scale or treatment of retinopathy with photocoagulation or vitrectomy. RESULTS: As previously reported, there were significant reductions in the primary outcome in the glycemia and dyslipidemia trials, but no significant effect in the blood pressure trial. Results were similar for retinopathy progression by 1, 2, and 4 or more steps on the person scale and for ≥ 2 steps on the eye scale. In the subgroup of patients with mild retinopathy at baseline, effect estimates were large (odds ratios, ∼0.30; P < 0.001), but did not reach nominal significance for participants with no retinopathy or for those with moderate to severe retinopathy at baseline. CONCLUSIONS: Slowing of progression of retinopathy by intensive treatment of glycemia was observed in ACCORD participants, whose average age and diabetes duration were 62 and 10 years, respectively, and who had cardiovascular disease or cardiovascular risk factors. The effect seemed stronger in patients with mild retinopathy. Similar slowing of progression was observed in patients treated with fenofibrate, with no effect observed with intensive blood pressure treatment. This is the second study to confirm the benefits of fenofibrate in reducing diabetic retinopathy progression, and fenofibrate should be considered for treatment of diabetic retinopathy.

RESUMEN

Gamma Knife Radiosurgery (GKRS) has been reported in the treatment of brainstem metastases while dose volume toxicity thresholds remain mostly undefined. A retrospective review of 52 brainstem metastases in 44 patients treated with GKRS was completed. A median dose of 18 Gy (range 10-22 Gy) was prescribed to the tumor margin (median 50 % isodose). 25 patients had undergone previous whole brain radiation therapy. Toxicity was graded by the LENT-SOMA scale. Mean and median follow-up was 10 and 6 months. Only 3 of the 44 patients are living. Multiple brain metastases were treated in 75 % of patients. Median size of lesions was 0.134 cc, (range 0.013-6.600 cc). Overall survival rate at 1 year was 32 % (95 % CI 51.0-20.1 %) with a median survival time of 6 months (95 % CI 5.0-16.5). Local control rate at 6 months and 1 year was 88 % (95 % CI 70-95 %) and 74 % (95 % CI 52-87 %). Cause of death was neurologic in 17 patients, non-neurologic in 20 patients, and unknown in four. Four patients experienced treatment related toxicities. Univariate analysis of tumor volume revealed that volume greater than 1.0 cc predicted for toxicity. A strategy of using lower marginal doses with GKRS to brain stem metastases appears to lead to a lower local control rate than seen with lesions treated within the standard dose range in other locations. Tumor size greater than 1.0 cc predicted for treatment-related toxicity.

RESUMEN

BACKGROUND: Gamma knife radiosurgery (GKRS) has been reported as a treatment option for multiple sclerosis (MS)-related trigeminal neuralgia. OBJECTIVE: To report the outcomes of a single-institution retrospective series of MS-related trigeminal neuralgia. METHODS: Between 2002 and 2010, 35 patients with MS-related trigeminal neuralgia were treated with GKRS. The median maximum dose was 90 Gy. Data were analyzed to determine the response to GKRS and factors that may predict for efficacy. RESULTS: Of the 35 patients, 88% experienced a Barrow Neurological Institute (BNI) pain score of I-III at 3 months after GKRS. Kaplan-Meier estimates of 1-, 2- and 5-year freedom from BNI IV-V pain relapse were 57, 57 and 52%, respectively. Numbness was experienced by 39% of patients after GKRS, though no patients reported bothersome numbness. Several differences were noted between how the MS-related variant responded to GKRS and what has previously been reported for idiopathic trigeminal neuralgia. These include the observations that development of post-GKRS numbness did not predict for treatment response (p = 0.62) and that dorsal root entry zone dose did not predict for freedom from pain relapse (odds ratio 1.01, p = 0.1). Active smoking predicted for freedom from pain relapse (odds ratio 67.4, p = 0.04). CONCLUSION: GKRS is a viable noninvasive treatment option for MS-related trigeminal neuralgia.

RESUMEN

BACKGROUND: We investigated whether intensive glycemic control, combination therapy for dyslipidemia, and intensive blood-pressure control would limit the progression of diabetic retinopathy in persons with type 2 diabetes. Previous data suggest that these systemic factors may be important in the development and progression of diabetic retinopathy. METHODS: In a randomized trial, we enrolled 10,251 participants with type 2 diabetes who were at high risk for cardiovascular disease to receive either intensive or standard treatment for glycemia (target glycated hemoglobin level, <6.0% or 7.0 to 7.9%, respectively) and also for dyslipidemia (160 mg daily of fenofibrate plus simvastatin or placebo plus simvastatin) or for systolic blood-pressure control (target, <120 or <140 mm Hg). A subgroup of 2856 participants was evaluated for the effects of these interventions at 4 years on the progression of diabetic retinopathy by 3 or more steps on the Early Treatment Diabetic Retinopathy Study Severity Scale (as assessed from seven-field stereoscopic fundus photographs, with 17 possible steps and a higher number of steps indicating greater severity) or the development of diabetic retinopathy necessitating laser photocoagulation or vitrectomy. RESULTS: At 4 years, the rates of progression of diabetic retinopathy were 7.3% with intensive glycemia treatment, versus 10.4% with standard therapy (adjusted odds ratio, 0.67; 95% confidence interval [CI], 0.51 to 0.87; P=0.003); 6.5% with fenofibrate for intensive dyslipidemia therapy, versus 10.2% with placebo (adjusted odds ratio, 0.60; 95% CI, 0.42 to 0.87; P=0.006); and 10.4% with intensive blood-pressure therapy, versus 8.8% with standard therapy (adjusted odds ratio, 1.23; 95% CI, 0.84 to 1.79; P=0.29). CONCLUSIONS: Intensive glycemic control and intensive combination treatment of dyslipidemia, but not intensive blood-pressure control, reduced the rate of progression of diabetic retinopathy.

RESUMEN

BACKGROUND: Errors and near misses are common in medicine. Checklists and similar interventions are feasible and can reduce the incidence of errors and improve patient outcomes. This study assessed the feasibility and efficacy of a checklist in a pediatric oncology clinic. PROCEDURE: Errors and near misses of all types were systematically tracked for 1 month in a pediatric oncology clinic. Following the initial 1 month time period (baseline), a 10-item checklist was implemented for each patient encounter during a 4-month period. During month 5 of the study while the checklist was being used, errors and near misses were again systematically tracked for 1 month. RESULTS: The use of a checklist was associated with a significant reduction of errors in our clinic. The total number of errors (including documentation errors) decreased from 133 in month 1 to 39 in month 5 (P < 0.0001). In addition, checklist use decreased the rate of encounters with at least one error from 34% to 15% (P < 0.001). The reduction in errors occurred despite the checklist not being used for each encounter. The majority of practitioners were satisfied with the use of a checklist and think that the use of a checklist is a good way to reduce errors. CONCLUSIONS: A checklist is potentially a feasible, safe, inexpensive, and simple method to lower the rate of medical errors in a pediatric oncology clinic.

RESUMEN

PURPOSE: To compare evaluation by clinical examination with image grading at a reading center for the classification of diabetic retinopathy and diabetic macular edema. METHODS: Action to Control Cardiovascular Risk in Diabetes (ACCORD) and Family Investigations of Nephropathy in Diabetes (FIND) had similar methods of clinical and fundus photograph evaluation. For analysis purposes, the photographic grading scales were condensed to correspond to the clinical scales, and agreement between clinicians and reading center classification were compared. RESULTS: Six thousand nine hundred and two eyes of ACCORD participants and 3,638 eyes of FIND participants were analyzed for agreement (percent, kappa) on diabetic retinopathy on a 5-level scale. Exact agreement between clinicians and reading center on diabetic retinopathy severity category was 69% in ACCORD and 74% in FIND (kappa 0.42 and 0.65). Sensitivities of the clinical grading to identify the presence of mild nonproliferative retinopathy or worse were 0.53 in ACCORD and 0.84 in FIND. Specificities were 0.97 and 0.96, respectively. Diabetic macular edema agreement in 6,649 eyes of ACCORD participants and 3,366 eyes of FIND participants was similar (kappa 0.35 and 0.41). Sensitivities of the clinical grading to identify diabetic macular edema were 0.44 and 0.53 and specificities were 0.99 and 0.94, respectively. CONCLUSION: The results support the use of clinical information for defining broad severity categories but not for documenting small-to-moderate changes in diabetic retinopathy over time.

RESUMEN

Quality improvement (QI) initiatives are critical in the care of older adults who are more vulnerable to substandard care. QI education meets aspects of core Accreditation Council of Graduate Medical Education competencies and prepares learners for the rising focus on performance measurement in health care. The authors developed, implemented, and evaluated a QI curriculum for geriatrics fellows. The evidence-based curriculum included didactics and a fellow-led QI intervention based on audit and feedback through the Practice Improvement Module in Care of the Vulnerable Elderly. QI knowledge, attitudes, and behaviors were assessed before and after the improvement project. Fellows' knowledge of QI improved (p = .0156), but behavior did not change significantly across a short-term improvement project. A structured focus group with fellows revealed themes of accountability and the importance of interprofessional teamwork in QI. QI education for geriatrics fellows can be feasible, well received, and prepare future physician leaders for patient-centered care, performance measurement, and effecting systems change.

RESUMEN

BACKGROUND: The optimal diagnostic strategy for patients with chest pain and detectable to mildly elevated serum troponin is not known. The objective was to compare clinical outcomes among an early decision for a noninvasive versus an invasive-based care pathway. METHODS: The CMR-IMPACT trial (Cardiac Magnetic Resonance Imaging Strategy for the Management of Patients with Acute Chest Pain and Detectable to Elevated Troponin) was conducted at 4 United States tertiary care hospitals from September 2013 to July 2018. A convenience sample of 312 participants with acute chest pain symptoms and a contemporary troponin between detectable and 1.0 ng/mL were randomized early in their care to 1 of 2 care pathways: invasive-based (n=156) or cardiac magnetic resonance (CMR)-based (n=156) with modification allowed as the patient condition evolved. The primary outcome was a composite including death, myocardial infarction, and cardiac-related hospital readmission or emergency visits. RESULTS: Participants (N=312, mean age, 60.6 years, SD 11.3; 125 women [59.9%]), were followed over a median of 2.6 years (95% CI, 2.4-2.9). Early assigned testing was initiated in 102 out of 156 (65.3%) CMR-based and 110 out of 156 (70.5%) invasive-based participants. The primary outcome (CMR-based versus invasive-based) occurred in 59% versus 52% (hazard ratio, 1.17 [95% CI, 0.86-1.57]), acute coronary syndrome after discharge 23% versus 22% (hazard ratio, 1.07 [95% CI, 0.67-1.71]), and invasive angiography at any time 52% versus 74% (hazard ratio, 0.66 [95% CI, 0.49-0.87]). Among patients completing CMR imaging, 55 out of 95 (58%) were safely identified for discharge based on a negative CMR and did not have angiography or revascularization within 90 days. Therapeutic yield of angiography was higher in the CMR-based arm (52 interventions in 81 angiographies [64.2%] versus 46 interventions in 115 angiographies [40.0%] in the invasive-based arm [P=0.001]). CONCLUSIONS: Initial management with CMR or invasive-based care pathways resulted in no detectable difference in clinical and safety event rates. The CMR-based pathway facilitated safe discharge, enriched the therapeutic yield of angiography, and reduced invasive angiography utilization over long-term follow-up. REGISTRATION: URL: https://www.

RESUMEN

OBJECTIVE: This study aimed to determine the impact of dietary weight loss (WL) plus aerobic exercise (EX) and a "move more, more often" approach to activity promotion (SitLess; SL) on WL and maintenance. METHODS: Low-active older adults (age 65-86 years) with obesity were randomized to WL+EX, WL+SL, or WL+EX+SL. Participants received a social-cognitive group-mediated behavioral WL program for 6 months, followed by a 12-month maintenance period. EX participants received guided walking exercise with the goal of walking 150 min/wk. SL attempted to achieve a step goal by moving frequently during the day. The primary outcome was body weight at 18 months, with secondary outcomes including weight regain from 6 to 18 months and objectively assessed physical activity and sedentary behavior at each time point. RESULTS: All groups demonstrated significant WL over 6 months (p < 0.001), with no group differences. Groups that received SL improved total activity time (p ≤ 0.05), and those who received EX improved moderate-to-vigorous activity time (p = 0.003). Over the 12-month follow-up period, those who received WL+EX demonstrated greater weight regain (5.2 kg; 95% CI: 3.5-6.9) relative to WL+SL (2.4 kg; 95% CI: 0.8-4.0). CONCLUSIONS: Pairing dietary WL with a recommendation to accumulate physical activity contributed to similar WL and less weight regain compared with traditional aerobic exercise.

RESUMEN

OBJECTIVES: This study aims to investigate the impact of respiratory symptoms in current and former smokers with and without obstructive lung disease (OLD) on all-cause mortality. DESIGN: Secondary analysis in a prospective cohort (the Health, Aging and Body Composition study). SETTING: Memphis, Tennessee, and Pittsburgh, Pennsylvania. PARTICIPANTS: Black and white men and women with a history of current and former smoking (N = 596; 63% male and 37% female) aged 70-79 years followed for 13 years. Participants were categorized into 4 mutually exclusive groups based on symptom profile and forced expiratory volume in the 1st second to forced vital capacity ratio. The groups were Less Dyspnea-No OLD (N = 196), More Dyspnea-No OLD (N = 104), Less Dyspnea-With OLD (N = 162), and More Dyspnea-With OLD (N = 134). MEASUREMENTS: All-cause mortality. RESULTS: Overall, 53% in Less Dyspnea-No OLD, 63% in More Dyspnea-No OLD, 67% in Less Dyspnea-With OLD, and 84% in More Dyspnea-With OLD died within the 13- year follow up period (log-rank χ2 = 44.4, P < .0001). The hazard ratio was highest for participants with OLD, both with (HR =1.91, 95% CI 1.44 - 2.54; P < .0001) and without dyspnea (HR = 1.52, 95% CI 1.15 - 2.02; p = .004). Participants without OLD but with dyspnea had a similar risk of death to subjects who had OLD but fewer symptoms. CONCLUSIONS: OLD is associated with high risk of death with different risk profiles based on symptom group. Patients with symptoms of shortness of breath without OLD should be considered an at-risk group given their similar mortality to those with OLD with minimal symptoms.

RESUMEN

This study aimed to determine the association between non-high-fat diet-induced obesity- (non-DIO-) associated gut microbiome dysbiosis with gut abnormalities like cellular turnover of intestinal cells, tight junctions, and mucin formation that can impact gut permeability. We used leptin-deficient (Lepob/ob) mice in comparison to C57BL/6J control mice, which are fed on identical diets, and performed comparative and correlative analyses of gut microbiome composition, gut permeability, intestinal structural changes, tight junction-mucin formation, cellular turnover, and stemness genes. We found that obesity impacted cellular turnover of the intestine with increased cell death and cell survival/proliferation gene expression with enhanced stemness, which are associated with increased intestinal permeability, changes in villi/crypt length, and decreased expression of tight junctions and mucus synthesis genes along with dysbiotic gut microbiome signature. Obesity-induced gut microbiome dysbiosis is also associated with abnormal intestinal organoid formation characterized with decreased budding and higher stemness. Results suggest that non-DIO-associated gut microbiome dysbiosis is associated with changes in the intestinal cell death versus cell proliferation homeostasis and functions to control tight junctions and mucous synthesis-regulating gut permeability.

RESUMEN

PURPOSE: To report the longitudinal association between use of thiazolidinediones (TZDs), visual acuity (VA) change, and diabetic eye disease incidence and progression. DESIGN: Cohort study ancillary to a randomized clinical trial. METHODS: We analyzed baseline and 4-year follow-up data of 2856 ACCORD trial participants with no history of proliferative diabetic retinopathy. Based on stereoscopic fundus photographs, we evaluated diabetic macular edema (DME) progression and DR progression. We also evaluated 10- and 15-letter change on the ETDRS visual acuity chart. Main outcome measures were incidence or progression of DME or DR and change in visual acuity. RESULTS: TZD use was not associated with DME incidence in either the analysis of any use (adjusted odds ratio [aOR] [95% CI]: 1.22 [0.72-2.05]) or duration of use (aOR: 1.02 [0.99-1.04]). Diabetic retinopathy (DR) incidence/progression was more common in patients with no or mild DR at baseline who were ever treated with TZDs (aOR: 1.68 [1.11-2.55]), but this association disappeared when adjusting for the time on TZD (aOR: 1.02 [1.00-1.04]). DR progression among those with moderate or worse DR at baseline was no different between TZD users and non-users. TZD usage had no effect on the ultimate visual acuity outcome. CONCLUSION: In this longitudinal study of patients with type 2 diabetes, we found no association between TZD use and visual acuity outcomes or DME progression, and no consistent evidence of increased DR progression in patients ever treated with TZDs vs those never treated with TZDs.

RESUMEN

BACKGROUND: Adults aged 65 years and older account for more than 33% of annual visits to internal medicine (IM) generalists and specialists. Geriatrics experiences are not standardized for IM residents. Data are lacking on IM residents' continuity experiences with older adults and competencies relevant to their care. OBJECTIVE: To explore patient demographics and the prevalence of common geriatric conditions in IM residents' continuity clinics. METHODS: We collected data on age and sex for all IM residents' active clinic patients during 2011-2012. Academic site continuity panels for 351 IM residents were drawn from 4 academic medical center sites. Common geriatric conditions, defined by Assessing Care of Vulnerable Elders measures and the American Geriatrics Society IM geriatrics competencies, were identified through International Classification of Disease, ninth edition, coded electronic problem lists for residents' patients aged 65 years and older and cross-checked by audit of 20% of patients' charts across 1 year. RESULTS: Patient panels for 351 IM residents (of a possible 411, 85%) were reviewed. Older adults made up 21% of patients in IM residents' panels (range, 14%-28%); patients ≥ 75 (8%) or 85 (2%) years old were relatively rare. Concordance between electronic problem lists and chart audit was poor for most core geriatric conditions. On chart audit, active management of core geriatric conditions was variable: for example, memory loss (10%-25%), falls/gait abnormality (26%-42%), and osteoporosis (11%-35%). CONCLUSIONS: The IM residents' exposure to core geriatric conditions and management of older adults was variable across 4 academic medical center sites and often lower than anticipated in community practice.

RESUMEN

The optimal integration of radiation and chemotherapy for limited-stage small-cell lung cancer (SCLC) remains unclear. This phase III trial was conducted to determine whether chemotherapy plus interdigitating split-course thoracic radiation therapy (RT) improved survival compared with standard-dose continuous thoracic RT. One hundred fourteen patients were randomized to receive 50 Gy thoracic RT delivered in 2.0-Gy fractions given continuously (5 weeks) concurrent with the first 2 cycles of chemotherapy (arm A) or 50 Gy delivered via an interdigitating split course in 2.5-Gy fractions (8 weeks) concurrent with the first 3 cycles of chemotherapy (arm B). During the split-course RT, once-daily radiation was delivered on days 8-17 of each of the first two 21-day cycles and days 8-11 of the third 21-day cycle. All patients received the following chemotherapy: cisplatin/etoposide on cycles 1, 2, and 5 and cyclophosphamide/vincristine/doxorubicin on cycles 3, 4, and 6. Prophylactic cranial irradiation was recommended after a complete response to all therapy. One hundred ten eligible patients were randomized. Grade 3/4 esophagitis was reported in 9% of patients receiving continuous thoracic RT versus 4% of patients receiving split-course RT. Grade 3/4 hematologic toxicity was common in both treatment arms. Complete/partial response was observed in 80% of patients on arm A versus 84% on arm B. Overall survival rates at 5 years were 18% and 17% for arms A and B, respectively. Interdigitating split-course thoracic RT delivered in 2.5-Gy fractions was tolerable in patients with limited-stage SCLC but did not provide a survival advantage.

RESUMEN

OBJECTIVES: To determine whether older adults with mild cognitive impairment (MCI), a condition not previously explored as a risk factor, have more hospitalizations and 30-day readmissions than those with normal cognition. DESIGN: Post hoc analysis of prospectively gathered data on incident hospitalization and readmission from the Ginkgo Evaluation of Memory Study (GEMS), a randomized, double-blind, placebo-controlled trial designed to assess the effect of Ginkgo biloba on incidence of dementia. SETTING: GEMS was conducted in five academic medical centers in the United States. PARTICIPANTS: Community-dwelling adults aged 75 and older with normal cognition (n = 2,314) or MCI (n = 428) at baseline cognitive testing (N = 2,742). MEASUREMENTS: Index hospitalization and 30-day hospital readmission, adjusted for age, sex, race, education, clinic site, trial assignment status, comorbidities, number of prescription medications, and living with an identified proxy. RESULTS: MCI was associated with a 17% greater risk of index hospitalization than normal cognition (adjusted hazard ratio (aHR) = 1.17, 95% confidence interval (CI) = 1.02-1.34)). In participants who lived with a proxy, MCI was associated with a 39% greater risk of index hospitalization (aHR = 1.39, 95% CI = 1.17-1.66). Baseline MCI was not associated with greater odds of 30-day hospital readmission (adjusted odds ratio = 0.90, 95% CI = 0.60-1.36). CONCLUSION: MCI may represent a target condition for healthcare providers to coordinate support services in an effort to reduce hospitalization and subsequent disability.

RESUMEN

BACKGROUND AND PURPOSE: Management for in-field failures after thoracic radiation is poorly defined. We evaluated SBRT as an initial or second course of treatment re-irradiating in a prior high dose region. MATERIALS AND METHODS: Thirty-three patients were treated with re-irradiation defined by the prior 30 Gy isodose line. Kaplan-Meier estimates were performed for local (LC), regional (RC), distant control (DC), and overall survival (OS). The plans when available were summed to evaluate doses to critical structures. Patient and treatment variables were analyzed on UVA for the impact on control and survival measures. RESULTS: Median follow-up was 17 months. Treatment for sequential courses was as follows: (course1:course2) EBRT:SBRT (24 patients), SBRT:SBRT (7 patients), and SBRT:EBRT (3 patients). Median re-irradiation dose and fractionation was 50 Gy and 10 fractions (fx), with a median of 18 months (6-61) between treatments. Median OS was 21 months and 2 year LC 67%, yet LC for >1 fraction was 88% (p=0.006 for single vs. multiple). 10 patients suffered chronic grade 2-3 toxicity (6 chest wall pain, 3 dyspnea, 1 esophagitis) and 1 grade 5 toxicity with aorta-esophageal fistula after 54 Gy in 3 fx for a central tumor with an estimated EQD2 to the aorta of 200 Gy. CONCLUSION: Tumor control can be established with re-irradiation using SBRT techniques for in-field thoracic failures at the cost of manageable toxicity.

RESUMEN

OBJECTIVE: Longitudinal evidence linking diabetic retinopathy with changes in brain structure and cognition is sparse. We used data from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial to determine whether diabetic retinopathy at baseline predicted changes in brain structure or cognition 40 months later. RESEARCH DESIGN AND METHODS: Participants from the ACCORD-MIND and ACCORD-Eye substudies were included in analyses of cognition (n = 1,862) and MRI-derived brain variables (n = 432). Retinopathy was categorized as none, mild nonproliferative, or moderate/severe. Tests of cognition included the Mini-Mental State Examination (MMSE), Digit Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test, and Stroop test. Primary brain outcomes were gray matter and abnormal white matter volumes. RESULTS: Baseline retinopathy was associated with lower gray matter volume (adjusted means of 470, 466, and 461 cm(3) for none, mild, and moderate/severe retinopathy, respectively; P = 0.03). Baseline retinopathy also predicted a greater change in MMSE and DSST scores at 40 months in each retinopathy category (MMSE: -0.20, -0.57, and -0.42, respectively [P = 0.04]; DSST: -1.30, -1.84, and -2.89, respectively [P = 0.01]). CONCLUSIONS: Diabetic retinopathy is associated with future cognitive decline in people with type 2 diabetes. Although diabetic retinopathy is not a perfect proxy for diabetes-related brain and cognitive decline, patients with type 2 diabetes and retinopathy represent a subgroup at higher risk for future cognitive decline.
