RESUMEN

BACKGROUND: It is important to identify patients at increased risk of worsening of left ventricular ejection fraction (LVEF) after a myocardial infarction (MI). We aimed to identify the association of various potential biomarkers with LVEF impairment after an MI in South American patients. METHODS: We studied adult patients admitted to a University Hospital and diagnosed with an acute MI. Plasma concentrations of high-sensitivity C-reactive protein (hsCRP), proprotein convertase subtilisin/kexin type 9 (PCSK9), N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and heart-type fatty-acid-binding protein (FABP3) were determined in samples drawn shortly after the event. Participants had a follow-up visit at least 45 days after the event. The primary endpoint was defined as any decline in LVEF at follow-up relative to baseline. RESULTS: The study included 106 patients (77.4% men, 22.6% women), mean age was 64.1, mean baseline LVEF was 56.6, 19% had a prior MI. We obtained a follow-up evaluation in 100 (94.4%) of participants, mean follow-up time was 163 days. There was a significant correlation between baseline PCSK9 and hsCRP (r = 0.39, p < 0.001). Baseline hsCRP concentrations were higher in patients who developed the endpoint than in those who did not (32.1 versus 21.2 mg/L, p = 0.066). After multivariate adjustment, baseline PCSK9, male sex and age were significantly associated with impairment in LVEF. The absolute change in LVEF was inversely correlated with baseline hsCRP (standardized coefficient = - 0.246, p = 0.004). CONCLUSION: High plasma levels of PCSK9 and hsCRP were associated with early decreases in LVEF after an MI in Latin American patients.

RESUMEN

BACKGROUND: International medical graduates (IMGs) have less burnout than U. S. medical school graduates (USMGs) during residency training. This study evaluates possible correlates of differences in burnout rates between USMGs and IMGs. METHODS: We surveyed 375 first-year residents at orientation in June/July 2017. We assessed burnout using the Copenhagen Burnout Inventory (CBI) and used validated scales to measure stress, quality of life (QoL), mastery, and spirituality. We collected data on gender, place of graduation, language fluency, and specialty. We compared CBI scores between USMGs and IMGs, performed a multivariate linear regression analysis of relationships between covariates and CBI subscales, and logistic regression analysis for our categorical definition of burnout. RESULTS: Two hundred twenty-two residents responded for a response rate of 59%. Personal, work or patient- related burnout was common among residents, particularly among USMGs. The most common form of burnout was work-related. Forty nine percent of USMGs have work burnout compared to 26% of IMGs (p < 0.01). In multivariate analysis, being an IMG reduced odds of work-related and of total burnout by 50% (OR 0.5 C.I 0.25-0.99). Perceived mastery was associated with reductions in all subscales of burnout (p < 0.05). Stress and low QoL related to personal and work burnout scores (p < 0.01). CONCLUSION: Work-related burnout is more common among USMGs than in IMGs. Although mastery, QoL and stress were correlates of burnout among all residents, these factors did not explain the difference. Future studies should evaluate the role of medical school structure and curriculum on differences in burnout rates between the two groups.

RESUMEN

Observational studies suggest outpatient metformin use is associated with reduced mortality from coronavirus disease-2019 (COVID-19). Metformin is known to decrease interleukin-6 and tumor-necrosis factor-α, which appear to contribute to morbidity in COVID-19. We sought to understand whether outpatient metformin use was associated with reduced odds of severe COVID-19 disease in a large US healthcare data set. Retrospective cohort analysis of electronic health record (EHR) data that was pooled across multiple EHR systems from 12 hospitals and 60 primary care clinics in the Midwest between March 4, 2020 and December 4, 2020. Inclusion criteria: data for body mass index (BMI) > 25 kg/m2 and a positive SARS-CoV-2 polymerase chain reaction test; age ≥ 30 and ≤85 years. Exclusion criteria: patient opt-out of research. Metformin is the exposure of interest, and death, admission, and intensive care unit admission are the outcomes of interest. Metformin was associated with a decrease in mortality from COVID-19, OR 0.32 (0.15, 0.66; p = .002), and in the propensity-matched cohorts, OR 0.38 (0.16, 0.91; p = .030). Metformin was associated with a nonsignificant decrease in hospital admission for COVID-19 in the overall cohort, OR 0.78 (0.58-1.04, p = .087). Among the subgroup with a hemoglobin HbA1c available (n = 1193), the adjusted odds of hospitalization (including adjustment for HbA1c) for metformin users was OR 0.75 (0.53-1.06, p = .105). Outpatient metformin use was associated with lower mortality and a trend towards decreased admission for COVID-19. Given metformin's low cost, established safety, and the mounting evidence of reduced severity of COVID-19 disease, metformin should be prospectively assessed for outpatient treatment of COVID-19.

RESUMEN

BACKGROUND: There are several reports of health disparities related to COVID-19. Understanding social determinants of health (SDoH) could help develop mitigation strategies to prevent further COVID-19 spread. Our aim is to evaluate self-reported and census-based SDoH as a mediator of health disparities in COVID-19. METHODS: We conducted a cross-sectional ecological study and included all COVID-19 cases report by the COVID-19 Florida dashboard as the dependent variable. The independent variables were census-based median household income, population and household size, and self-reported SDoH using a validated survey. We calculated the incidence rate ratio (IRR) of COVID-19 by zip code using Poisson regression and structured equation modelling to evaluate the mediation effect of income and SDoH on COVID-19 cases. RESULTS: We included 97,594 COVID-19 positive cases across 79 Miami-Dade ZIP codes with a median age of 43 years; females represented 50.7% of the cases. The highest IRR (4.44) were for ZIP code 33125 (income $21,106, 6% Black, 93% Hispanic), while the lowest IRR (0.86) was for ZIP code 33146 (median household incomes $96,609, 3% Black and 53% Hispanic). In structured equation models, the indirect coefficient of income in the relationship between race/ethnicity and COVID-19 were only significant for Blacks and not Hispanics. CONCLUSIONS: This ecological analysis using ZIP code and aggregate individual-level SDoH shows that in Miami-Dade county, COVID infection is associated with economic disadvantage in a particular geographical area and not with racial/ethnic distribution.

RESUMEN

OBJECTIVE: Inferior vena cava (IVC) injuries have a high mortality rate that may be related to the location of injury and type of repair. Previous studies have been either single center series or database studies lacking granular detail. These have reported conflicting results. We aimed to perform a systematic review and meta-analysis of published literature evaluating ligation versus repair. METHODS: Studies published in English on MEDLINE or EMBASE from 1946 through October 2018 were examined to evaluate mortality among patients treated with ligation versus repair of IVC injuries. Studies were included if they provided mortality associated with ligation versus repair and reported IVC injury by level. Risk of bias was assessed regarding incomplete and selective outcome reporting with Newcastle-Ottawa score of 7 or higher to evaluate study quality. We used a random-effects model with restricted maximum likelihood estimation method in R using the Metafor package to evaluate outcomes. RESULTS: Our systematic review identified 26 studies, of which 14 studies, including 855 patients, met our inclusion criteria for meta-analysis. IVC ligation was associated with higher mortality than IVC repair (OR: 3.12, P < 0.01, I2 = 49%). Ligation of infrarenal IVC injuries was not statistically associated with mortality (OR: 3.13, P = 0.09). Suprarenal injury location compared to infrarenal (OR 3.11, P < 0.01, I2 = 28%) and blunt mechanism compared to penetrating (OR: 1.91, P = 0.02, I2 = 0%) were also associated with higher mortality. CONCLUSIONS: In this meta-analysis, ligation of IVC injuries was associated with increased mortality compared to repair, but not specifically for infrarenal IVC injuries. Suprarenal IVC injury, and blunt mechanism was associated with increased mortality compared to infrarenal IVC injury and penetrating mechanism, respectively. Data are limited regarding acute renal injury and venous thromboembolic events after IVC ligation and may warrant multicenter studies. Standardized reporting of IVC injury data has not been well established and is needed in order to enable comparison of outcomes across institutions. In particular, reporting of injury location, severity, and repair type should be standardized. A contemporary prospective, multicenter study is needed in order to definitively compare surgical technique.

RESUMEN

BACKGROUND: Weight regain (WR) after bariatric surgery is common. Several factors involved in WR have been identified, but there has been little research on specific eating habits such as eating snacks rather than regular meals and being a "sweet-eater". AIM: To determine whether nutritional status, energy and macronutrient intake, eating behaviors and habits were associated with WR in the postoperative period. MATERIAL AND METHODS: We conducted a case-control study of patients who had undergone bariatric surgery. Cases were defined as those patients who gained ≥ 15% of weight in the first two years after surgery and controls as those who gained < 15% of weight. Participants completed a 24-hour dietary recall by phone; weight history was obtained from the medical chart. Logistic regression was used to identify nutritional and behavioral factors significantly related to WR. RESULTS: Fifty-four cases (77% female, 57% had undergone sleeve gastrectomy) and 50 controls (70% female, 58% had undergone Roux-en-Y gastric bypass surgery) participated. Their mean age was 43 and 40 years, respectively. We observed four eating and lifestyle habits independently associated with greater odds of post-surgery WR, namely being a "sweet-eater", a "grazer", sedentarism and consuming more daily calories. CONCLUSIONS: Eating more daily calories, being a "sweet-eater", a "grazer", and sedentarism were factors related with a greater risk of regaining weight after surgery.

RESUMEN

BACKGROUND: Bariatric surgery (BS) is the most effective procedure in the management of obesity, achieving a significant decrease in energy intake. AIM: To measure calorie and macronutrient intake in patients subjected to gastric bypass (GBP) or sleeve gastrectomy (SG). MATERIAL AND METHODS: We studied 53 patients subjected to SG and 27 subjected to GBP, who were in the first, second or sixth postoperative month. A food frequency consumption survey was applied by specialized nutritionists and their nutritional status was assessed. RESULTS: Mean calorie intake in months 1, 2 and 6 were 505, 600 and 829.8 kcal, respectively. A significantly higher intake was observed at month 1 in patients with those subjected to SG, compared with GBP patients. Protein consumption was <60 g/d, except at 6 months in patients with GBP. At months 1, 2 and 6, mean consumption of lipids were 17, 28 and 30 g/day, respectively. The figures for carbohydrates were 42, 31 and 77 g/day, respectively. At month 1, patients with GBP had a higher BMI, equalizing at 6 months with those of SG. At 6 months 37% of patients had a normal body mass index and 17% remained obese. A negative correlation was observed between weight loss and energy intake during the first month (rho: -0.40; p = 0.033). CONCLUSIONS: Patients subjected to BS had a low calorie and macronutrient intake in the first six postoperative months. Their calorie intake is negatively associated with weight loss, mainly during the first postoperative month.

RESUMEN

Cleft palate (CP) is a common birth defect occurring in 1 in 2,500 live births. Approximately half of infants with CP have a syndromic form, exhibiting other physical and cognitive disabilities. The other half have nonsyndromic CP, and to date, few genes associated with risk for nonsyndromic CP have been characterized. To identify such risk factors, we performed a genome-wide association study of this disorder. We discovered a genome-wide significant association with a missense variant in GRHL3 (p.Thr454Met [c.1361C>T]; rs41268753; p = 4.08 × 10(-9)) and replicated the result in an independent sample of case and control subjects. In both the discovery and replication samples, rs41268753 conferred increased risk for CP (OR = 8.3, 95% CI 4.1-16.8; OR = 2.16, 95% CI 1.43-3.27, respectively). In luciferase transactivation assays, p.Thr454Met had about one-third of the activity of wild-type GRHL3, and in zebrafish embryos, perturbed periderm development. We conclude that this mutation is an etiologic variant for nonsyndromic CP and is one of few functional variants identified to date for nonsyndromic orofacial clefting. This finding advances our understanding of the genetic basis of craniofacial development and might ultimately lead to improvements in recurrence risk prediction, treatment, and prognosis.

RESUMEN

BACKGROUND: A clinically based sudden cardiac death (SCD) risk score has predictive value. Echocardiographic parameters predict SCD. Our aim was to evaluate the effect of adding echocardiographic parameters to the clinical SCD risk score for the prediction of all-cause mortality. METHODS: We conducted a retrospective cohort of screening echocardiograms performed on primary care patients. We calculated the SCD risk score and added the left ventricular (LV) mass index, LV hypertrophy, diastolic dysfunction, and LV ejection fraction (EF). We calculated the c-statistic, net reclassification index (NRI), and Hosmer-Lemeshow chi-square for the SCD score alone or combined with each echocardiographic parameter in predicting all-cause mortality. RESULTS: We included 6447 primary care patients who underwent a screening echocardiogram and had a SCD score. The c-statistic of the SCD score for mortality was 0.61; 95% CI 0.58-0.62 and the c-statistic for the score combined with LV mass index increased to 0.64; 95% CI 0.63-0.65 and for the score combined with LVEF, the c-statistic was 0.64;95% CI 0.63-0.67. When diastolic dysfunction and LV hypertrophy were added to the SCD score, the c-statistic did not significantly change (P > 0.05). The NRI for the addition of LV mass index and LVEF was 0.52 ± 0.02, and the Hosmer-Lemeshow statistic was nonsignificant (P > 0.05). CONCLUSIONS: Adding LV mass index or LVEF to the SCD risk score improves the ability to predict mortality, but in the primary care setting, the improvement is small and underscores the challenge of SCD prediction and prevention in the community.

RESUMEN

OBJECTIVES: This systematic review/meta-analysis examines the potential for older people to accept and use tablet technology in clinical settings by assessing satisfaction and effectiveness. METHODS: A comprehensive literature search was conducted of PubMed, SCOPUS, and CINAHL through March 2017. Inclusion criteria included studies with any clinical use of a tablet technology with a median patient age above 65 years. RESULTS: We included a total of 12 studies (4 randomized controlled trials, 4 cross-sectional studies, and 4 pre/post studies). Interventions included the use of tablet technology for medication self-management, post-surgery education, memory retention, cognitive rehabilitation, and exercise promotion. The use of tablet technology by older people in clinical settings was associated with high satisfaction with a pooled prevalence of satisfaction of 78%; 95% CI 27-100. We did not find evidence for effectiveness in improving clinical or behavioral outcomes. CONCLUSIONS: Older people can use and are satisfied with table technology in clinical settings. More studies are needed to evaluate the effectiveness of tablet technology at promoting health outcomes. CLINICAL IMPLICATIONS: Clinicians should be encouraged to utilize tablet technology in the care of older patients.

RESUMEN

Orofacial clefts (OFCs), which include non-syndromic cleft lip with or without cleft palate (CL/P), are among the most common birth defects in humans, affecting approximately 1 in 700 newborns. CL/P is phenotypically heterogeneous and has a complex etiology caused by genetic and environmental factors. Previous genome-wide association studies (GWASs) have identified at least 15 risk loci for CL/P. As these loci do not account for all of the genetic variance of CL/P, we hypothesized the existence of additional risk loci. We conducted a multiethnic GWAS in 6480 participants (823 unrelated cases, 1700 unrelated controls and 1319 case-parent trios) with European, Asian, African and Central and South American ancestry. Our GWAS revealed novel associations on 2p24 near FAM49A, a gene of unknown function (P = 4.22 × 10-8), and 19q13 near RHPN2, a gene involved in organizing the actin cytoskeleton (P = 4.17 × 10-8). Other regions reaching genome-wide significance were 1p36 (PAX7), 1p22 (ARHGAP29), 1q32 (IRF6), 8q24 and 17p13 (NTN1), all reported in previous GWASs. Stratification by ancestry group revealed a novel association with a region on 17q23 (P = 2.92 × 10-8) among individuals with European ancestry. This region included several promising candidates including TANC2, an oncogene required for development, and DCAF7, a scaffolding protein required for craniofacial development. In the Central and South American ancestry group, significant associations with loci previously identified in Asian or European ancestry groups reflected their admixed ancestry. In summary, we have identified novel CL/P risk loci and suggest new genes involved in craniofacial development, confirming the highly heterogeneous etiology of OFCs.

RESUMEN

BACKGROUND: Non-Hispanic blacks (NHB) and Hispanics often present with advanced colorectal cancer (CRC). The aim of the study was to characterize CRC differences among Hispanics, NHB, and non-Hispanic whites (NHW). METHODS: A cross-sectional analysis and logistic regression of 2009 Florida Agency for Healthcare Administration Hospital Admission Database data for CRC using the International Classification of Diseases, 9th Revision, Clinical Modification codes was performed. Outcomes included CRC location, frequency of metastasis and colectomy rates. Each minority group was compared with NHW. RESULTS: A total of 34,577 patients were NHW, 5190 were NHB, and 5033 were Hispanic. NHB had more proximal CRC [odds ratio (OR), 1.17; 95% confidence interval (CI), 1.09-1.25; P<0.0001]; Hispanics had more distal CRC (OR, 0.90; 95% CI, 0.83-0.96; P=0.0024). Hispanics had increased metastases (OR, 1.11; 95% CI, 1.02-1.22; P=0.04). NHB and Hispanics underwent fewer colectomies [(OR, 0.93; 95% CI, 0.86-0.99; P=0.03) and (OR, 0.9; 95% CI, 0.84-0.97; P=0.001), respectively]. CONCLUSIONS: Disparities in CRC metastases and colectomy rates exist among these racial groups in Florida. This work should serve as a foundation to study potential causes and to design culture-specific interventions.

RESUMEN

Improved life expectancy in hemophilia has led to a greater interest in age-related disorders. Hypertension (HTN) as well as cardiovascular disease have been increasingly reported in hemophilic adults but there is currently very limited data in the pediatric population. We conducted a cross-sectional study using data from the 2012 National Health Cost and Utilization Project database to determine the prevalence of HTN and associated cardiovascular risk factors in a hospitalized pediatric hemophilia population, between the ages of 0 to 21 years, in comparison with the general pediatric population. The prevalence of HTN was significantly higher in children with hemophilia (CWH) in comparison with the general pediatric population (1.71% vs. 1.02%, P-value=0.005). When adjusting the analysis for sex, the prevalence of HTN in the hemophilia cohort remained higher, although not statistically significant (1.52% vs. 1.22%, P-value=0.2568). When examining the concomitant presence of ≥1 cardiovascular risk factors in the hypertensive subgroups, CWH had a higher prevalence of obesity (2.64% vs. 1.32%, P-value <0.0001). Interestingly, diabetes mellitus was more prevalent in nonhemophilic children (1.47% vs. 0.56%, P-value=0.0015). These data suggest that cardiovascular risk factors need to be closely monitored in CWH, and a better preventive strategy is likely needed to identify those hemophilic patients at higher risk of developing cardiovascular disease in adulthood.

RESUMEN

INTRODUCTION: The incidence of inflammatory bowel disease (IBD) among US Hispanics is rising. Adoption of an American diet and/or US acculturation may help explain this rise. AIMS: To measure changes in diet occurring with immigration to the USA in IBD patients and controls, and to compare US acculturation between Hispanics with versus without IBD. Last, we examine the current diet of Hispanics with IBD compared to the diet of Hispanic controls. METHODS: This was a cross-sectional study of Hispanic immigrants with and without IBD. Participants were recruited from a university-based GI clinic. All participants completed an abbreviated version of the Stephenson Multi-Group Acculturation Scale and a 24-h diet recall (the ASA-24). Diet quality was calculated using the Healthy Eating Index (HEI-2010). RESULTS: We included 58 participants: 29 controls and 29 IBD patients. Most participants were Cuban or Colombian. Most participants, particularly those with IBD, reported changing their diet after immigration (72% of IBD and 57% of controls). IBD participants and controls scored similarly on US and Hispanic acculturation measures. IBD patients and controls scored equally poorly on the HEI-2010, although they differed on specific measures of poor intake. IBD patients reported a higher intake of refined grains and lower consumption of fruits, whereas controls reported higher intake of empty calories (derived from fat and alcohol). CONCLUSION: The majority of Hispanics change their diet upon immigration to the USA and eat poorly irrespective of the presence of IBD. Future studies should examine gene-diet interactions to better understand underlying causes of IBD in Hispanics.

RESUMEN

BACKGROUND: Randomized clinical trials (RCTs) conducted among heart failure (HF) patients have reported that mobile technologies can improve HF-related outcomes. Our aim was to conduct a meta-analysis to evaluate m-Health's impact on healthcare services utilization, mortality, and cost. METHODS: We searched MEDLINE, Cochrane, CINAHL, and EMBASE for studies published between 1966 and May-2017. We included studies that compared the use of m-Health in HF patients to usual care. m-Health is defined as the use of mobile computing and communication technologies to record and transmit data. The outcomes were HF-related and all-cause hospital days, cost, admissions, and mortality. RESULTS: Our search strategy resulted in 1,494 articles. We included 10 RCTs and 1 quasi-experimental study, which represented 3,109 patients in North America and Europe. Patient average age range was 53-80 years, New York Heart Association (NYHA) class III, and Left Ventricular Ejection Fraction <50%. Patients were mostly monitored daily and followed for an average of 6 months. A reduction was seen in HF-related hospital days. Nonsignificant reductions were seen in HF-related cost, admissions, and mortality and total mortality. We found no significant differences for all-cause hospital days and admissions, and an increase in total cost. CONCLUSIONS: m-Health reduced HF-related hospital days, showed reduction trends in total mortality and HF-related admissions, mortality and cost, and increased total costs related to more clinic visits and implementation of new technologies. More studies reporting consistent quality outcomes are warranted to give conclusive information about the effectiveness and cost-effectiveness of m-Health interventions for HF.

RESUMEN

In a world where the population is ageing, there is growing interest and demand for research evaluating strategies that address the ageing process. After 60 years of successful use of metformin in our pharmaceutical armamentarium, we are learning that, beyond improving glycaemic control, metformin may have additional mechanisms and pathways of action that need further study. Although, metformin's effect on clinical ageing outcomes may still be considered speculative, the findings from studies into cellular and animal models and from observational and pilot human studies support the existence of beneficial effects on ageing. At present, progress for human research, using randomised clinical trials to evaluate metformin's clinical impact, has just started. Here, we present a review on the ageing process and the mechanisms involved, and the role that metformin may have to counter these. We go on to discuss the upcoming large randomised clinical trials that may provide insight on the use of metformin for ageing outcomes beyond glycaemic control.

RESUMEN

This study investigates the presence of Merkel cell polyomavirus (MCPyV) in skin lesions of patients with Merkel cell carcinoma (MCC). MCPyV was quantified using quantitative Real-Time-PCR (qRT-PCR) in 34 paraffinized MCC samples (resected/biopsied) originally taken between 1977 and 2015, and six non-MCC samples. In 31 (91.2%) MCC-individuals, MCPyV was detected. No virus was observed in any non-MCC tumor. Average age at diagnosis was 78.2 ± 9.35 (55-97) years for women (n = 19) and 69.5 ± 14.7 (45-91) for men (n = 15) (P = 0.04). MCC tumor location, known in 25 cases, was: 11 (44%) in the head region, 6 (24%) in upper limbs, 4 (16%) in lower limbs, and 4 (16%) in the trunk. All but one patient had received some sort of treatment: 15 (45.45%) underwent both radio and chemotherapy, 13 (39.39%) only surgery, 2 (6.06%) surgery, plus radio and chemotherapy, 2 (6.06%) surgery and chemotherapy, and 1 (3.03%) only radiotherapy. Follow up data were available for 21/34 patients: recurrence was recorded for 4 (19.04%), and metastasis for 13 (61.9%). Recorded data showed that 10 men and 5 women (total 44.1%) died during follow up, 7 (46.7%) of them within 2 years of diagnosis. Viral load was 5.8 ± 1.4 log copies/105 cells (3.1-8.6), independent of any variable. MCPyV was very frequent in MCC. It was principally associated with head and limb tumors, it more commonly affected men, who in this study were, on average, younger than women, and had high rates of recurrence and mortality. The amplification techniques described here are easily applied and suitable for detecting the presence of MCPyV virus in MCC.

RESUMEN

OBJECTIVES: To evaluate the impact of the April 2016 7.8-magnitude earthquake in Ecuador on the incidence of Zika virus (ZIKV) cases. METHODS: We used the national public health surveillance system for reportable transmissible conditions and included suspected and laboratory-confirmed ZIKV cases. We compared the number of cases before and after the earthquake in areas closer to and farther from the epicenter. RESULTS: From January to July 2016, 2234 patients suspected of having ZIKV infection were reported in both affected and control areas. A total of 1110 patients had a reverse transcription-polymerase chain reaction assay, and 159 were positive for ZIKV. The cumulative incidence of ZIKV in the affected area was 11.1 per 100 000 after the earthquake. The odds ratio of having ZIKV infection in those living in the affected area was 8.0 (95% CI = 4.4, 14.6; P < .01) compared with the control area and adjusted for age, gender, province population, and number of government health care facilities. CONCLUSIONS: A spike in ZIKV cases occurred after the earthquake. Patients in the area closest to the epicenter had a delay in seeking care.
