Abstract
Abstract
Objective
Insulin resistance increases the risk of developing type 2 diabetes and subsequently cardiovascular and cerebrovascular disease. It is also linked to neurocognitive disorders and accelerated cognitive aging (Ekblad et al, 2017; Levine, Harrati, & Crimmins, 2018). Using baseline data from a longitudinal study in a sample of 126 cognitively intact adults aged 25–50 years (36.5% males), we assessed cognitive performance in relation to insulin resistance to determine whether an early prodromal pattern of cognitive changes exists prior to advanced metabolic disease.
Methods
Steady state plasma glucose (SSPG) was used to measure insulin resistance. Multivariate regression analyses were conducted using age, years of education, body mass index (BMI), and SSPG as predictors of neuropsychological functioning. In-person and tele-neuropsychological assessment was administered using standard neuropsychological measures.
Results
Higher insulin resistance was associated with significantly worse attention (WAIS-III Digit Span total; B = -0.018, p = 0.03), executive functioning (D-KEFS Color-Word Inhibition/Switching; B = 0.047, p = 0.04) and dominant fine motor abilities (Purdue Pegboard; B = -0.008, p = 0.02). Higher insulin resistance was also associated with trend level worsening of other measures of executive functioning, namely D-KEFS Trails 4 (B = 0.099, p = 0.07) and DKEFS Color-Word Inhibition errors (B = 0.007, p = 0.09).
Conclusions
In young adults, higher insulin resistance was associated with declines in attention, executive functioning, and fine motor abilities. This early pattern of subtle cognitive changes associated with higher insulin resistance seen in this sample of younger adults is consistent with later cognitive declines found in type 2 diabetes and vascular neurocognitive disorder, namely declines in attention, executive functioning, and motor abilities with eventual memory declines in advanced disease.

Abstract
OBJECTIVE This study aimed to identify differences in sequential integrated screening and early ultrasound markers in monochorionic/diamniotic (MC/DA) pregnancies complicated by twin-to-twin transfusion syndrome (TTTS) and unequal placental sharing (UPS). STUDY DESIGN Retrospective cohort study of MC/DA pregnancies evaluated between January 2012 and July 2017 at the University of California San Francisco. MC/DA pregnancies with ultrasound surveillance up to 26 weeks who participated in the California Prenatal Screening Program (CPSP) were included. Pregnancies with structural or genetic anomalies were excluded. UPS was defined as an intertwin growth discordance ≥20%. Intertwin nuchal translucency (NT) discordance was calculated by the absolute value of the difference of the NT of cotwins. Kruskal-Wallis or ANOVA testing was performed where appropriate, and negative binomial regression models were chosen to test for differences in mean biomarker levels by outcome group. RESULTS A total of 191 MC/DA pregnancies were included; 85 were affected by TTTS, 35 by UPS, and 71 controls. Significant differences in intertwin NT discordance in pregnancies complicated by TTTS and UPS compared with controls (p = 0.007) were found. TTTS cases had a mean NT discordance greater than two times that of controls (p = 0.04), while UPS cases had a value more than three times greater (p = 0.003). There was a statistically significant difference in mean second trimester human chorionic gonadotropin (hCG) between the cohorts (p = 0.0002) with TTTS cases having a mean second trimester hCG value 1.5 greater than both controls (p < 0.001) and UPS cases (p = 0.001). Analysis showed a significant difference in mean second trimester inhibin between the three cohorts (p = 0.029). Pregnancies complicated by UPS had a mean second trimester inhibin 1.5 times greater than controls (p = 0.010). CONCLUSION Our study shows that there are unique differences in early ultrasound and sequential integrated serum markers between MC/DA gestations complicated by TTTS and UPS versus those unaffected. KEY POINTS · Differences exist in sequential integrated screening markers in monochorionic-diamniotic twin pregnancies.. · Early risk stratification of monochorionic-diamniotic twin pregnancies may be possible.. · Sequential integrated screening testing can provide useful information to clinicians when evaluating monochorionic-diamnitoic twin pregnancies..

Background
Nitroglycerin (GTN) results in improved CCTA image quality and diagnostic accuracy due to vasodilation and improved contrast density. Although studies have shown that sublingual (SL) GTN spray has greater vasodilation and faster onset and duration of action compared to SL tablet, it is not commonly used due to cost. The comparative efficacy of SL GTN powder in CCTA is unknown.
Purpose
The purpose of this study is to determine whether SL GTN powder can increase the coronary lumen volume (V) and the coronary lumen volume to left myocardial mass ratio (V/M) compared to SL GTN tablet.
Methods
34 patients (17 females) with 0.8 mg SL GTN powder and 34 patients (17 females) with 0.8 mg SL GTN tablet administration were included in this retrospective case-control study. GTN was given 5 minutes pre-CCTA on a 256 slice single-heartbeat CT. Inclusion criteria: CAD-RADS 0 or 1, precontrast LM + LAD AJ-130 CAC < 100, heart rate less than 75, phase of the cardiac cycle diastole, successful motion correction, Likert score 4 or 5, right- or co-dominance. The primary outcome assessed was left main plus left anterior descending (LM + LAD) V between GTN powder vs tablet. The secondary outcomes were LM + LAD V divided by 1) length of LM + LAD (derived mean area, A), and 2) M (V/M). The outcomes were measured by blinded PI with 17 yrs CCTA experience on GE workstation, 2020 version. Categorical variables were compared by Chi-Squared tests and continuous variables were compared between powder and tablet groups by unpaired t-tests if normally distributed, and Mann-Whitney U tests otherwise. Exploratory outcome analyses tested route of administration by sex interactions and main effects by Two-Way ANOVA’s. Further covariate-adjusted analyses were conducted using multiple linear regression models.
Results
Baseline characteristics were similar between powder and tablet administration. No statistically significant difference in median V, LM + LAD derived A , or median V/M was observed. A sex main effect demonstrated that females had significantly smaller V (630.6 mm3 vs 951.7 mm3, p< 0.0001) and A (4.2 mm2 vs 6.4 mm2, p< 0.0001) compared to males. These V and A sex differences were also observed when BMI or weight were included as covariates. When V and A were normalized by M, both revealed sex interactions depending on formulation. While males had higher normalized V and A in powder vs tablet (p < 0.04), females had the opposite with higher normalized V and A with tablet compared to powder (p < 0.04).
Conclusions
SL administration of the GTN powder 5 minutes before CCTA did not result in greater vasodilatory effect compared to the GTN tablet. However, gender interaction effects were observed, with greater V/M and A/M ratio in males with powder and greater V/M and A/M in women with tablet. These results suggest a potential differential gender effect based on the formulation of GTN. Prospective studies are warranted to evaluate these findings.

Abstract
Abstract
Background
The effectiveness of catheter ablation as a management modality amongst patients with coexisting atrial flutter (AFL) and heart failure with reduced ejection fraction (HFrEF) is scarcely studied.
Methods
Appropriate ICD 10 codes were applied to the 2016 and 2017 National Readmission Database (NRD) to isolate patients having coexistent AFL and HFrEF including who had undergone an ablation. All-cause mortality at the end of 1 year was used as a primary outcome. Readmission due to AFL, heart failure (HF) and other causes were secondary outcomes. The hazard ratios were generated using Cox regression analysis while the time to event analysis was demonstrated with the Kaplan Meier curves.
Results
Out of a total of 9966 patients with AFL and HFrEF, 1980 (24.79%) patients underwent catheter ablation. The primary outcome, all-cause mortality (2.8% vs. 4.6%, HR: 0.610, 95% CI: 0.460–0.808, p=0.001) at the end of 1 year was significantly lower. Significant difference was also noted amongst two groups when it came to secondary outcomes such as readmissions due to AFL (1.6% vs. 6.3%, HR: 0.247, 95% CI: 0.173–0.354, p<0.001), HF (8.2% vs. 11.4%, HR: 0.693, 95% CI: 0.587–0.819, p<0.001) and other causes (29.4% vs. 37.1%, HR: 0.735, 95% CI: 0.673–0.804, p<0.001)
Conclusion
Ablative intervention amongst AFL patients with concomitant HFrEF showed a significant reduction in all-cause mortality. It also leads to significant reductions in readmissions due to AFL, HF and other causes at the end of one year.

Abstract
Abstract
Background
The availability of real-world data regarding the impact of the catheter ablation in patients with concomitant atrial flutter (AFL) and heart failure with preserved ejection fraction (HFpEF) is limited.
Methods
2016 and 2017 National Readmission Database (NRD) was subjected to appropriate ICD-10 codes to identify and extract patients having coexistent atrial flutter and heart failure with preserved ejection fraction including who had undergone ablation. At 1 year, all-cause mortality was utilized as the primary outcome while readmissions due to AFL, heart failure (HF) and any other causes were designated as secondary outcomes. Kaplan Meier curves were used for a time to event analysis. Cox proportional hazard regression was used to generate hazard ratios.
Results
Out of a total 6099 patients with AFL and HFpEF, 906 (14.85%) underwent catheter ablation. At 1 year all cause mortality (3%, vs. 4.4%, HR: 0.661, 95% CI: 0.444–0.985, p=0.042) and readmissions due to AFL (2.3% vs. 5.3%, HR: 0.424, 95% CI: 0.272–0.661, p<0.001) were significantly less among ablation group. Readmission due to HF (9.3% vs. 9.7%, HR: 0.938, 95% CI: 0.745–1.182, p=0.587) and other causes (37% vs.40.3%, HR: 0.926, 95% CI: 0.825–1.040, p=0.193) did not show any significant difference in outcomes at the end of 1 year.
Conclusion
The utilization of catheter ablation amongst AFL patients with concomitant HFpEF showed a significant reduction in all-cause mortality and readmission due to AFL. However, it did not show any significant changes in readmissions due to HF or other causes at the end of one year.

Abstract
BACKGROUND Every year, Puerto Rico faces a hurricane season fraught with potentially catastrophic structural, emotional and health consequences. In 2017, Puerto Rico was hit by Hurricane Maria, the largest natural disaster to ever affect the island. Several studies have estimated the excess morbidity and mortality following Hurricane Maria in Puerto Rico, yet no study has comprehensively examined the underlying health system weaknesses contributing to the deleterious health outcomes. METHODS A qualitative case study was conducted to assess the ability of the UPR health system to provide patient care in response to Hurricane Maria. An established five key resilience framework and inductive analysis was used to identify factors that affected health system resilience. Thirteen Emergency Medicine Physicians, Family Medicine Physicians, and Hospital Administrators in a University of Puerto Rico (UPR) Community Hospital were interviewed as part of our study. RESULTS Of the five key resiliency components, three domains were notably weak with respect to UPR resiliency. Prior to the Hurricane, key personnel at the UPR hospital were unaware of the limited capacity of back-up generators at hospitals and were ill-prepared to transfer ICU patients to appropriate hospitals. Post Hurricane, the hospital faced self-regulation challenges when triaging the provision of Hurricane-related emergency services with delivering core health services, in particular for patients with chronic conditions. Finally, during and after the Hurricane, integration of patient care coordination between the UPR hospital ambulances, neighboring hospitals, and national and state government was suboptimal. The two remaining resiliency factors, addressing diverse needs and system adaptiveness in a time of crisis, were seen as strengths. CONCLUSIONS Hurricane Maria exposed weaknesses in the Puerto Rican health system, notably the lack of awareness about the limited capacity of backup generators, poor patient care coordination, and interruption of medical care for patients with chronic conditions. As in other countries, the current COVID epidemic is taxing the capacity of the Puerto Rico health system, which could increase the likelihood of another health system collapse should another hurricane hit the island. Therefore, a resilience framework is a useful tool to help health systems identify areas of improvement in preparation for possible natural disasters.

Abstract
Importance Reducing cesarean delivery rates in the US is an important public health goal; despite evidence of the safety of vaginal birth after cesarean delivery, most women have scheduled repeat cesarean deliveries. A decision support tool could help increase trial-of-labor rates. Objective To analyze the effect of a patient-centered decision support tool on rates of trial of labor and vaginal birth after cesarean delivery and decision quality. Design, Setting, and Participants Multicenter, randomized, parallel-group clinical trial conducted in Boston, Chicago, and the San Francisco Bay area. A total of 1485 English- or Spanish-speaking women with 1 prior cesarean delivery and no contraindication to trial of labor were enrolled between January 2016 and January 2019; follow-up was completed in June 2019. Interventions Participants were randomized to use a tablet-based decision support tool prior to 25 weeks' gestation (n=742) or to receive usual care (without the tool) (n=743). Main Outcomes and Measures The primary outcome was trial of labor; vaginal birth was the main secondary outcome. Other secondary outcomes focused on maternal and neonatal outcomes and decision quality. Results Among 1485 patients (mean age, 34.0 [SD, 4.5] years), 1470 (99.0%) completed the trial (n = 735 in both randomization groups) and were included in the analysis. Trial-of-labor rates did not differ significantly between intervention and control groups (43.3% vs 46.2%, respectively; adjusted absolute risk difference, -2.78% [95% CI, -7.80% to 2.25%]; adjusted relative risk, 0.94 [95% CI, 0.84-1.05]). There were no statistically significant differences in vaginal birth rates (31.8% in both groups; adjusted absolute risk difference, -0.04% [95% CI, -4.80% to 4.71%]; adjusted relative risk, 1.00 [95% CI, 0.86-1.16]) or in any of the other 6 clinical maternal and neonatal secondary outcomes. There also were no significant differences between the intervention and control groups in the 5 decision quality measures (eg, mean decisional conflict scores were 17.2 and 17.5, respectively; adjusted mean difference, -0.38 [95% CI, -1.81 to 1.05]; scores >25 are considered clinically important). Conclusions and Relevance Among women with 1 previous cesarean delivery, use of a decision support tool compared with usual care did not significantly change the rate of trial of labor. Further research may be needed to assess the efficacy of this tool in other clinical settings or when implemented at other times in pregnancy.

Abstract
The debate over trafficking of human beings for the purpose of organ removal (THBOR) remains largely absent from policy debates, as its crime is hardly detected, reported and sparsely researched. However, criminal networks continue to exploit vulnerable populations, particularly migrants. To help bridge this gap in knowledge, we employ a bibliometric analysis to examine whether the nexus between organ removal and migration is being addressed by the current academic literature. Our results indicate that (1) research exploring the link between THBOR and migrants is relatively scarce; (2) organ trafficking literature output is largely clustered in a couple of Western countries, and (3) despite the international nature of the topic, most empirical studies on organ trafficking and migration lack representation within the social sciences and humanities. Taken together, our results point to a huge gap on scientific publications between THBOR and migration. Quantitative data is required to lift the current knowledge constraints and better inform policymakers.

Abstract
Purpose
The purpose of this paper is to provide a comprehensive methodology and a case study about the successful integration of FCA with continuous improvement tools for strategic decision-making processes. Reliable knowledge of the condition of tangible assets and their ability to fulfill their target activities over time are required for an assertive strategical decision process. Facility condition assessment (FCA) is a recognized methodology that allows the systematic evaluation of this performance. For those companies whose primary objective is the production of goods, decisions associated with improvements on the productive system or re-adaptation of existing assets may also require the implementation of alternative methodologies, with a direct impact on the indicators of the company and therefore on the FCA.
Design/methodology/approach
This study presents a methodology for the integration of FCA and lean manufacturing (LM) as a tool in strategic decision-making process that involves the integration of continuous improvement processes or significant changes in the production process, in which the condition of the installation impacts decisively the productivity of the system.
Findings
The results of the implementation on an insecticide and herbicide production plant indicate an increase of 33 per cent in the capacity of the formulation process and over 20 per cent reduction in the internal quality claims associated with the packaging system.
Practical implications
Those methodological stages are applicable to facilities in which the FCA shows the need for significant reconditioning of assets, the need to increase the efficiency and/or the production capacity. This methodology integrates elements of continuous improvement and redesign of production systems.
Originality/value
The original value of this paper is oriented to the capacity to integrate different FCA and LM tools through the company indicators of productivity key performance indicators and, in addition, of a comprehensive illustration based on a study case.

Abstract
BACKGROUND The current AAP clinical practice guidelines for the management of pediatric obesity recommend a structured, comprehensive, multi-disciplinary clinical intervention. However, there is a gap in the current literature on standardized curriculums for implementation of such programs. The objective of the present study is to adapt an evidenced-based, family- centered, weekly, weight management curriculum that addresses nutritional, physical activity and behavioral topics for a clinical care model at a tertiary care children's hospital. METHODS The curriculum was adapted for use in six individual sessions offered monthly by a multidisciplinary team, including a health educator, physician, dietitian, physical therapist and psychologist. Each provider offered specific feedback and curriculum adaptation based on their specialty. All team members completed training with scheduled treatment fidelity monitoring during implementation. To evaluate the effectiveness of the adapted curriculum, 60 adolescents, ages 14-18 years, with overweight or obesity, and at least one family member, will complete the six month intervention. The primary outcome is mean change in zBMI and %BMIp95 at six month and 18 months. Secondary outcomes include retention, satisfaction, effect on metabolic factors and activity level. CONCLUSION There is a paucity of literature on utilizing a standard curriculum in clinical weight management programs. Drawing from evidenced-based curriculum to strengthen clinical care creates an opportunity to improve existing clinical programs and potentially increase access and implementation of the current treatment recommendations for this high risk population.

Abstract
For the last 5 years Accelogic pioneered and perfected a radically new theory of numerical computing codenamed “Compressive Computing”, which has an extremely profound impact on real-world computer science [1]. At the core of this new theory is the discovery of one of its fundamental theorems which states that, under very general conditions, the vast majority (typically between 70% and 80%) of the bits used in modern large-scale numerical computations are absolutely irrelevant for the accuracy of the end result. This theory of Compressive Computing provides mechanisms able to identify (with high intelligence and surgical accuracy) the number of bits (i.e., the precision) that can be used to represent numbers without affecting the substance of the end results, as they are computed and vary in real time. The bottom line outcome would be to provide a state-of-the-art compression algorithm that surpasses those currently available in the ROOT framework, with the purpose of enabling substantial economic and operational gains (including speedup) for High Energy and Nuclear Physics data storage/analysis. In our initial studies, a factor of nearly x4 (3.9) compression was achieved with RHIC/STAR data where ROOT compression managed only x1.4.
In this contribution, we will present our concepts of “functionally lossless compression”, have a glance at examples and achievements in other communities, present the results and outcome of our current, ongoing R&D, as well as present a high-level view of our plan to move forward with a ROOT implementation that would deliver a basic solution readily integrated into HENP applications. As a collaboration of experimental scientists, private industry, and the ROOT Team, our aim is to capitalize on the substantial success delivered by the initial effort and produce a robust technology properly packaged as an open-source tool that could be used by virtually every experiment around the world as means for improving data management and accessibility.

Abstract
BACKGROUND AND AIM Talc poudrage has been used since many years for sclerosing chronic pleural effusion. Several reports have shown good results managing chronic seromas after breast, vascular, and incisional hernia surgeries. The purpose of this study is to determine the utility of talc seromadesis for the management of chronic seromas after incisional hernia surgery. MATERIALS AND METHODS Multicentric prospective observational study including patients diagnosed of chronic seromas after incisional hernia surgery. Under local anesthesia and ultrasonographic control, two percutaneous trocars were placed in the seroma, washing the seroma cavity with 0.9% saline solution and aspirating the remaining liquid. A sample of 4 g of talcum powder was introduced in the seroma cavity, and a 15-F drain was left in place. Patients were followed each week during at least 4 weeks after drainage removal. RESULTS Between January 2013 and December 2016, a total of six patients were enrolled in the study. Talc poudrage was performed without any complications. Drains were pulled out in a mean time of 3 (range: 2-4) weeks. One case of the chronic seromas was efficiently sclerosed with talc without recurrence in time. In three cases, the seroma recurred, and the final solution was surgical decortication of the seroma. In the other two cases, seroma also recurred and were managed with instillation of ethanol and iodine povidone. CONCLUSION In our experience, the management of chronic seromas after incisional hernia repair with talc seromadesis is ineffective and is associated with a high rate of seroma recurrence.

Abstract
ObjectivesThe objective of this study was to evaluate the impact of quality grade on beef eating quality of top sirloin steaks when cooked to multiple degrees of doneness (DOD).Materials and MethodsBeef top sirloin butts (IMPS #184; N = 60; 15/quality grade) were collected to equally represent 4 quality grades [Prime, Top Choice (Modest and Moderate marbling), Low Choice, and Select]. Top butts were cut into six consecutive steaks, and then divided laterally to get a total of twelve steaks per top butt. Steaks were assigned to one of three DOD: rare (60°C), medium (71°C), and well-done (77°C). Steaks within each DOD were assigned to consumer sensory analysis, trained sensory analysis, fat and moisture analysis, and Warner-Bratzler shear force (WBSF). Consumers (N = 236) were fed samples under red lighting and evaluated steaks for juiciness, tenderness, flavor, and overall liking on continuous line scales. Trained sensory panelists evaluated samples for initial and sustained juiciness, myofibrillar and overall tenderness, connective tissue amount, beef flavor intensity, and off flavor intensity on similar continuous line scales. Data were analyzed as a split-plot, with a whole plot factor of quality grade, and sub-plot factor of DOD.ResultsThere were no interactions (P > 0.05) for all consumer ratings of palatability traits. For quality grade, no differences (P > 0.05) were observed for consumer ratings of tenderness, flavor, and overall liking; however, there was a significant effect (P = 0.01) on juiciness. Prime top sirloin steaks had higher (P < 0.05) juiciness ratings than all other quality grades, except for Top Choice. Additionally, as DOD increased, consumer ratings and the percentage of steaks rated acceptable for all palatability traits decreased (P < 0.05; rare > medium > well-done). There was a quality grade × DOD interaction (P < 0.05) for trained sensory ratings of myofibrillar tenderness, initial juiciness, and sustained juiciness. When steaks were cooked to medium, Prime and Top Choice steaks had higher (P < 0.05) panelist ratings for initial and sustained juiciness than Low Choice and Select steaks. Similar to trained panelist ratings of juiciness, Prime and Top Choice steaks had higher (P < 0.05) ratings of myofibrillar tenderness than Select steaks. Prime and Top Choice steaks had similar (P > 0.05) and higher (P < 0.05) ratings for myofibrillar tenderness when compared to Low Choice steaks. Within DOD, each successive increase in DOD resulted in a concurrent decrease (P < 0.05; rare > medium > well) in trained panelist ratings of myofibrillar tenderness, initial juiciness, and sustained juiciness. There was no quality grade by DOD interactions (P > 0.05) for Warner-Bratzler shear force. Prime steaks were more (P < 0.05) tender than Low Choice and Select steaks but were similar (P > 0.05) to Top Choice. Moreover, as DOD increased, WBSF concurrently increased (P < 0.05; well-done > medium > rare), with well-done steaks having WBSF values 0.8 kg tougher than rare steaks.ConclusionThese results indicate that regardless of DOD, quality grade had minimal impact on the palatability of beef top sirloin steaks. Therefore, unless cooked to a medium DOD, it is unnecessary for consumers, retailers, and foodservice to pay premium prices for higher quality top sirloin steaks, as the same eating experience will be provided.

Abstract
ObjectivesTo evaluate quality attributes of beef longissimus dorsi (LD) during 15 d of simulated retail display using surface and internal bioelectrical impedance analysis (BIA) measurement techniques.Materials and MethodsThe experiment was designed as a split-plot with loin as the whole-plot and pairekd steaks as the sub-plot. Display day (DD) was treated as the sub-plot treatment. Postmortem age time (PM) and DD were treated as fixed effects. Beef strip loins (N = 18; IMPS #180), obtained from 3 commercial processors (PM = 27, 34, or 37 d), were fabricated into 12 2.54-cm thick steaks (N = 216). Steaks were subdivided into 6 consecutively cut pairs and pairs were randomly assigned to one of 6 display days: 0, 3, 6, 9, 12, and 15. For all pairs, one steak was allocated to microbiological analysis and pH and the paired steak for BIA, objective color assessment, proximate composition, and TBARS. Surface BIA (S-BIA) and internal BIA (I-BIA) assessment were compared. Steaks were packaged on styrofoam trays with a moisture absorbent pad, overwrapped with polyvinyl chloride film, and displayed under fluorescent lighting at 0–4°C in coffin-style retail cases.ResultsThere was a PM × DD interaction (P < 0.05) for S-BIA values. From d 0 to 12 of display, steaks aged 27 d had higher (P < 0.05) S-BIA values than steaks aged 34 and 37 d; however, on d 15 of display, steaks aged 34 d had 22% higher (P < 0.05) S-BIA values than steaks aged 37 d, but had similar (P > 0.05) values compared to steaks aged 27 d. There was no PM × DD interaction (P < 0.05) for I-BIA values; however, an effect on PM and DD was found (P < 0.05). Steaks aged 27 d were 17% higher for I-BIA values (P < 0.05) than 37 d, but similar (P > 0.05) to steaks aged 34 d. For all PM aging times, d 0 had the lowest (P < 0.05) I-BIA values among all display days with 81.44. D 3 was the second lowest (P < 0.05) and 8% higher than d 0 for I-BIA values. D 6 was 16% higher (P < 0.05) than d 3 but similar (P > 0.05) to d 9 and d 12. D 12 and D 15 were similar (P > 0.05). There was a DD × BIA method interaction (P < 0.05). On d 0, 3, and 6, BIA values were different (P < 0.05); however, after d 6 onward, BIA values were similar (P > 0.05). Covariance component was smaller in I-BIA than S-BIA. There were no PM × DD interactions (P > 0.05) for a* and b* values; however, there was an interaction for L* values. Postmortem aging had no effect (P > 0.05) on L*; however, an effect on a* and b* was found (P < 0.05). For APC populations, there was a PM × DD interaction (P < 0.05). No PM × DD interaction or PM effect (P > 0.05) were found for TBARS; however, there was a DD effect (P < 0.05). There was no PM day × DD interaction (P > 0.05) or PM day (P > 0.05) for moisture content. Display day (P < 0.05) had an effect on moisture content. Moderate negative correlations occurred between S-BIA values and a*, b*, and moisture content with –0.48, –0.46, and –0.46, respectively; and –0.51, –0.48, and –0.43, respectively, for I-BIA. Conversely, moderate positive correlation was found between S-BIA values and APC and TBARS with 0.34 and 0.53, respectively; and 0.29 and 0.51, respectively, for I-BIA.ConclusionI-BIA has potential for use to assess shelf-life of retail steaks and it was more precise than S-BIA; however, I-BIA may translocate bacteria into the muscle. Protein degradation and WHC should be evaluated to better understand BIA changes over time.

Abstract
Abstract
Objective
Barriers like poor health literacy and patient-provider communication add to health disparities in diverse populations. Perceived autonomy has been shown to improve patients’ health satisfaction and knowledge of their illness. However, no studies have examined these issues in HIV patients. This study examined the roles of health literacy and physician-patient relationship in health outcomes (e.g., mental health and emotional/physical functioning) in persons living with HIV (PLWH).
Participants and Method
This cross-sectional study included 91 PLWH (74% Latinx and 26% non-Latinx White; 68% Male) who completed the Test of Functional Health Literacy in Adults (TOFHLA), Physician–Patient Relationship Scale (PPRS), and Medical Outcomes Study-HIV Health Survey (MOS). The study variables included: TOFHLA total score, PPRS Part Decision- Making (PDM) and Trust subscales, and MOS Mental Health and Health Transition subscales.
Results
A linear regression showed that our model (ethnicity, TOFHLA, PPRS PDM and Trust) predicted MOS HT (R2 = .14, p < 0.05), such that Latinx ethnicity (β = .30) and better TOFHLA scores (β = -.22) predicted better MOS HT scores (ps < .05). Another regression showed that our model predicted MOS MH (R2 = 0.07, p = <.01), such that greater PPRS PDM scores predicted better MOS MH scores (β = .27, p = <.01).
Conclusions
Ethnicity and better health literacy were related to improved emotional/physical functioning over a 4-week period and greater shared decision-making was related to better overall mental health. These findings highlight the importance of identifying sociocultural factors and interpersonal processes of care to inform culturally-tailored interventions that can result in enhanced and effective treatment for PLWH patients and in improved physical and mental health outcomes.

Abstract
Abstract
Heart failure with mid-range ejection fraction (HFmrEF) has been recognized as a distinct HF phenotype, but wether patients on this category fare worse, similarly, or better than those with HF with reduced EF (HFrEF) or preserved EF (HFpEF) in terms of rehospitalization risk over time remains unclear. We therefore sought to characterize the mordibity burden of HFmrEF patients by evaluating the risk of recurrent hospitalizations following an admission for acute HF.
Methods
We prospectively included 2,961 consecutive patients discharged for acute HF in our institution from 2004 to 2017. Patients were categorized according to their ejection fraction (EF) obtained by an echocardiography during the index admission: HFmrEF (EF 41–49%), HFrEF (EF≤40%) and HFpEF (EF≥50%). Negative binomial regression method was used to evaluate the association between EF status and recurrent all-cause and HF-related admissions. Risk estimates were expressed as incidence ratio ratios (IRR).
Results
Mean age of the cohort was 73.9±11.1 years, 49% were women, and 46.0% had suffered from previous HF admissions. 472 patients (15.9%) had HFmrEF, 956 (32.3%) had HFrEF, and 1,533 (51.8%) had HFpEF. At a median (interquartile range) follow-up of 2.4 (4.4) years, 1,821 (61.5%) patients died and 6,035 all-cause readmissions were registered in 2,026 patients (68.4%), being 2,163 of them HF-related. Rates of all-cause readmission per 100 patients-years of follow-up were 43.4, 47.1 and 50.1 per HFrEF, HFmrEF and HFpEF categories, respectively. After multivariable adjustment, and compared to patients with HFrEF, HFmrEF status was not associated with a higher risk of all-cause or HF-related recurrent admissions (IRR=1.06; 95% confidence interval (CI), 0.93–1.20; p=0.89), and IRR=1.07; 95% CI, 0.91–1.26; p=0.389, respectively), whereas HFpEF status was associated with a non-significant increase in the risk of all-cause recurrent admissions but a similar risk of HF-related readmissions (IRR=1.10; 95% confidence interval (CI), 0.99–1.22; p=0.06, and IRR=1.01; 95% CI, 0.88–1.16; p=0.900, respectively)
Conclusion
Following an admission for acute HF, patients with HFmrEF have a similar all-cause and HF-related rehospitalization burden when compared to patients with HFrEF, by means of recurrent events analysis.

Abstract
Abstract
Introduction
Cardiac magnetic resonance (CMR) has emerged as the most potent non-invasive imaging technique for risk stratification after ST-segment elevation myocardial infarction (STEMI) but an indiscriminate use in all patients is unfeasible. Echocardiography (Echo) has been universally used for prognostication in this scenario. We hypothesized that left ventricular ejection fraction (LVEF) by Echo can represent the gatekeeper for selecting those patients who benefit most from CMR for prognostic purposes.
Methods
Data were obtained from a large prospective registry of reperfused STEMI patients (n=516) in whom Echo (2D and Doppler variables) and CMR (cine images, microvascular obstruction and infarct size) were simultaneously recorded at pre-discharge (7±2 days). Major adverse cardiac events (MACE) were defined as a combined clinical end-point: death or re-admission for acute heart failure (whichever occurred first). Patients were categorized in reduced LVEF (r-LVEF, <40%), mid-range LVEF (mr-LVEF, 40–49%) and preserved LVEF (p-LVEF, ≥50%). Hierarchical multivariate Cox regression analyses including first clinical+Echo variables and then CMR variables where carried out. C-statistics, “net reclassification” (NRI) and “integrated discrimination” (IDI) indexes were obtained.
Results
During a mean and median follow-up of 4 years, 86 first MACE (17%) were registered (39 deaths and 47 re-admissions for acute heart failure). In the whole study group (n=516), the independent predictors of MACE were time to revascularization (min), GRACE score, CMR-LVEF (%) and CMR-microvascular obstruction (% of LV mass); C-statistic 0.82 (p<0.001). The MACE rate in patients with r-LVEF, mr-LVEF and p-LVEF was 47%, 23% and 11% by Echo-LVEF and 45%, 17% and 8% by CMR-LVEF. LVEF was lower by CMR than by Echo (51±13 vs. 54±10, p<0.001) and r-LVEF was more frequently detected by CMR (n=94, 18%) than by Echo (n=48, 9%), p<0.001. CMR significantly improved clinical+Echo stratification in those 112 patients (22%) with mr-Echo-LVEF (C-statistitics 0.74 vs 0.82; NRI and IDI: p<0.05) but it did not in those 355 patients (69%) with p-Echo-LVEF (C-statistitics 0.75 vs 0.76; NRI and IDI: non-significant) and in those 49 patients (9%) with r-Echo-LVEF (C-statistitics 0.77 vs 0.77; NRI and IDI: non-significant).
Figure 1. Risk stratification after STEMI
Conclusions
Applied in an individualized manner, Echo-LVEF appears as a useful gatekeeper for a selective use of CMR soon after STEMI for prognostic purposes. The event rate is high in patients with reduced Echo-LVEF and low in those with preserved Echo-LVEF; CMR does not seem to significantly improve risk stratification in these scenarios. Nevertheless, the occurrence of mid-range Echo-LVEF permits discriminating the specific subset of STEMI patients (less than a quarter) who really benefit from pre-discharge CMR in terms of risk assessment.
