Abstract
High-resolution imaging, 3D modeling, and quantitative analyses are equipping evolutionary biologists with new approaches to understanding the variation and evolution of the musculoskeletal system. However, challenges with interpreting DiceCT data and higher order use of modeled muscles have not yet been fully explored, and the error in and accuracy of some digital methods remain unclear. West Indian Anolis lizards are a model clade for exploring patterns in functional adaptation, ecomorphology, and sexual size dimorphism in vertebrates. These lizards possess numerous jaw muscles with potentially different anatomies that sculpt the adductor chamber of the skull. Here we test approaches to quantifying the musculoskeletal shape of the heads of two species of Anolis: A. pulchellus and A. sagrei. We employ comparative approaches such as DiceCT segmentation of jaw muscles, 3D surface attachment mapping, and 3D landmarking with the aim of exploring muscle volumes, 3D muscle fiber architecture, and sexual dimorphism of the skull. We then compare sources of measurement error in these 3D analyses while also presenting new 3D musculoskeletal data from the Anolis feeding apparatus. These findings demonstrate the accessibility and repeatability of these emerging techniques as well as provide details regarding the musculoskeletal anatomy of the heads of A. pulchellus and A. sagrei which show potential for further research of comparative biomechanics and evolution in the clade.

Abstract
AIMS Cervical cancer incidence and mortality rates are approximately 55% higher in the Rio Grande Valley (RGV) along the Texas-Mexico border compared with the average rates in the US. Our aim was to improve cervical cancer prevention efforts in the RGV through a comprehensive multilevel intervention initiative focused on community education, patient navigation, and training of local providers. METHODS We initiated a program in the RGV which consisted of (1) community education, (2) patient navigation, and (3) a training/mentoring program for local medical providers including hands-on training courses coupled with telementoring using Project ECHO® (Extension for Community Health Outcomes). We assessed the number of women undergoing cervical cancer screening, diagnosis, and treatment at three participating clinics caring for underserved women in the region. RESULTS From November 2014 to October 2018, 14,846 women underwent cervical cancer screening. A total of 2030 (13.7%) women underwent colposcopy for abnormal results (179% increase over baseline) and 453 women underwent loop electrosurgical excision procedures (LEEPs) for treatment of cervical dysplasia. Invasive cancer was diagnosed in 39 women who were navigated to a gynecologic oncologist for treatment. Seven local medical providers were trained to perform colposcopy and/or LEEP. Project ECHO telementoring videoconferences were held every 2 weeks for a total 101 sessions with an average of 22 participants per session and a total of 180 patient cases presented and discussed. CONCLUSIONS Our program led to a large number of women undergoing diagnosis and treatment of cervical dysplasia in the RGV. If sustained, we anticipate these efforts will decrease cervical cancer rates in the region. The program is currently being expanded to additional underserved areas of Texas and globally to low- and middle-income countries.

Abstract
Abstract
Aim
The purpose of this work is to elucidate if low cumulative doxorubicin doses has a differential cardiac impact in pigs with or without pre-existing LV pressure overload. Impact of interventions on LV anatomy, function and tissue composition was evaluated by serial cardiac magnetic resonance (CMR). At the end of the in vivo protocol, hearts were processed to evaluate differential molecular pathways in both groups.
Methods
A total of 95 pigs were included. 52 animals underwent supravalvular aortic banding to generate LV hypertrophy, while another did not. 4 months after banding (a time where LV hypertrophy is prominent), animals in both groups were randomized to receive intravenous doxorubicin (1 mg/kg once per week, for 5 weeks) or saline. Thus, 4 study groups (N=15–22 per group) comprised the study population (banding yes/no, doxorubicin yes/no). All individuals underwent to serial Cardiac Magnetic Resonance exams every month and were sacrificed fo ex vivo analysisat 4 months after doxorubicin injections. To discriminate between doxorubicin effect in banding/no banding groups but also the effect of banding in doxorubicin protocols, t-test was used for two-group comparisons after two-way ANOVA test. Differences were considered statistically significant at p<0.05. Logrank test was performed to compare survival curves.
Results
Pigs receiving doxorubicin after cardiac pressure overload showed an increased mortality compared with the other groups (p=0.006). Only this group developed a progressive cardiotoxicity phenotype, characterized as a significant decline in cardiac function compared with control operated animals (49.7% ± 8.1 vs 79.6% ± 6.7, p<0.001), but also with non-operated pigs receiving the same anthracycline regime (vs 63.9% ± 4, p<0.001). Cardiac deterioration was based mainly on systolic dysfunction compared with control operated animals (38.2 ml indexed ± 3.5 vs 13.6±6.6, p=0.01) and non-operated pigs treated with doxorubicin (vs 26.6 ml indexed ± 6.6, p<0.001). In-vivo CMR tissue characterization revealed elevation on T2 relaxation times compared with Control animals (46.2 ms ± 3.5 vs 41.8±2.7, p=0.04) with no Extracellular Volume expansion. Ex-vivo histological analyses showed presence of intra-cardiomyocyte vacuolization in the Banding + DOXO group (p=0.01). Regarding mitochondrial phenotype, animals with Banding + DOXO exhibited a fragmented phenotype with extremely damaged mitochondria. Animals with only aortic banding exhibit increasing cardiac hyperkinesia and cardiac hypertrophy at the end of the study.
Conclusion(s)
We demonstrated that a very low dosage of doxorubicin is enough to exert cardiotoxicity in a pressure overload scenario. Characterized as a deterioration in cardiac function, myocardial edema, classical histological lesions and mitochondrial damage. Providing preclinical evidence that modest anthracycline protocols may be harmful for patients with cardiac comorbidities.

Abstract
Abstract
Background
Atrial fibrillation (AF) in elderly patients increases both bleeding and thromboembolic risks. Elderly patients benefit as much from anticoagulation therapy with positive net clinical benefit. However, there have been few studies that focused on the efficacy and safety of direct oral anticoagulants in elderly patients.
The aim of this subanalysis from EMIR study was to assess the effectiveness of rivaroxaban in patients older than 75 years old.
Methods
EMIR Study (acronym from 'Estudio observacional para la identificaciόn de los factores de riesgo asociados a eventos cardiovasculares Mayores en pacientes con fIbrilaciόn auricular no valvular tratados con un anticoagulante oral directo (Rivaroxaban)') was an observational, multicenter, post-authorization and prospective study that involved AF patients under oral anticoagulation with rivaroxaban at least 6 months before enrolment. We analyzed baseline clinical characteristics and adverse events after 2.5 years of follow up.
Results
We analyzed 1,433 patients with median age of 74.7 (67.7–81.6). Of them 691 (48.2%) were ≥75 years. Elderly patients had higher prevalence of cardiovascular risk factors such previous stroke (16.8% vs 8.5%; p<0.001), heart failure (25.0% vs 20.6%; p<0.001), higher CHA2DS2-VASc (4.4±1.3 vs 2.7±1.2; p<0.001) and HAS-BLED (1.9±1.0 vs 1.2±1.0; p<0.001) scores. After 2.5 (2.2–2.6) years of follow-up, we observed low rate of adverse events in patients under rivaroxaban therapy. We observed higher rate of adverse events in elderly population for thromboembolic events (1.13%/year vs 0.36%/year; p=0.017) and major bleeding events (1.80%/year vs 0.36%/year; p<0.001) but those adverse rates were lower than expected according to previous studies (i.e. ROCKET-AF trial, rivaroxaban group had 4.86%/year of major bleeding or in XANTUS study was 3.2%/year of major bleeding in patients >75 years). We did not observe differences between groups from MACE (1.13%/year vs 1.01%/year; p=0.875) or cardiovascular death (0.86%/year vs 0.42%/year; p=0.170).
Conclusion
In real-world elderly population, rivaroxaban showed higher rates of thromboembolic and major bleeding events in elderly patients but with annual rates lower than expected according to previous studies like ROCKET-AF or XANTUS. Similar annual rates in elderly were observed for MACE and cardiovascular mortality than in younger patients, being rivaroxaban a good therapeutic alternative even for the elderly.

Abstract
BACKGROUND Understanding and improving obstetrical quality and safety is an important goal of professional societies, and many interventions such as checklists, safety bundles, educational interventions, or other culture changes have been implemented to improve the quality of care provided to obstetrical patients. Although many factors contribute to delivery decisions, a reduced workload has addressed how provider issues such as fatigue or behaviors surrounding impending shift changes may influence the delivery mode and outcomes. OBJECTIVE The objective was to assess whether intrapartum obstetrical interventions and adverse outcomes differ based on the temporal proximity of the delivery to the attending's shift change. STUDY DESIGN This was a secondary analysis from a multicenter obstetrical cohort in which all patients with cephalic, singleton gestations who attempted vaginal birth were eligible for inclusion. The primary exposure used to quantify the relationship between the proximity of the provider to their shift change and a delivery intervention was the ratio of time from the most recent attending shift change to vaginal delivery or decision for cesarean delivery to the total length of the shift. Ratios were used to represent the proportion of time completed in the shift by normalizing for varying shift lengths. A sensitivity analysis restricted to patients who were delivered by physicians working 12-hour shifts was performed. Outcomes chosen included cesarean delivery, episiotomy, third- or fourth-degree perineal laceration, 5-minute Apgar score of <4, and neonatal intensive care unit admission. Chi-squared tests were used to evaluate outcomes based on the proportion of the attending's shift completed. Adjusted and unadjusted logistic models fitting a cubic spline (when indicated) were used to determine whether the frequency of outcomes throughout the shift occurred in a statistically significant, nonlinear pattern RESULTS: Of the 82,851 patients eligible for inclusion, 47,262 (57%) had ratio data available and constituted the analyzable sample. Deliveries were evenly distributed throughout shifts, with 50.6% taking place in the first half of shifts. There were no statistically significant differences in the frequency of cesarean delivery, episiotomy, third- or fourth-degree perineal lacerations, or 5-minute Apgar scores of <4 based on the proportion of the shift completed. The findings were unchanged when evaluated with a cubic spline in unadjusted and adjusted logistic models. Sensitivity analyses performed on the 22.2% of patients who were delivered by a physician completing a 12-hour shift showed similar findings. There was a small increase in the frequency of neonatal intensive care unit admissions with a greater proportion of the shift completed (adjusted P=.009), but the findings did not persist in the sensitivity analysis. CONCLUSION Clinically significant differences in obstetrical interventions and outcomes do not seem to exist based on the temporal proximity to the attending physician's shift change. Future work should attempt to directly study unit culture and provider fatigue to further investigate opportunities to improve obstetrical quality of care, and additional studies are needed to corroborate these findings in community settings.

Abstract
Background:Rheumatoid arthritis (RA) is a chronic autoimmune disease with no cure, characterized by episodes of exacerbation and remission, which requires permanent use of medications. Clinics of excellence are multidisciplinary and centralized programs that improve adherence to treatments. Information on the benefits of these models of care has been published but is not definitive. In Colombia, the clinical registry of patients with RA is kept in the Cuenta de Alto Costo (CAC).Objectives:To demonstrate the difference in the percentages of sustained remission at 2 years, between an institution with non-centralized management or standard of care (Hospital Militar Central-HMC) compared to another institution with centralized management or clinic of excellence (BIOMAB-IPS) and determine if the results are determined by any of the intervention variables or by the program.Methods:The 2-year clinical records for the CAC were compared between an institution with non-centralized management (HMC) in comparison with another institution with centralized management (BIOMAB-IPS), performing a sociodemographic description, measuring control of the disease DAS28 clinimetry, Fisher’s test non-parametric bivariate analysis, multiple regression model, and population matching with Propensity score Matching (PSM).Results:Complete information was obtained from 2 years of follow-up, in centralized management 3457 patients and for the non-centralized unit 114 patients. Most of them corresponded to 2962 women (82%), with time of illness of 9.5 years and 10.2 years, respectively, without statistically significant differences. A difference was observed in the 2 programs to maintain remission at 2 years, in favor of the centralized program 54.7% vs 28.6.2% (p <0.00). With the binomial generalized linear regression model, it was confirmed that this difference was not explained by variables such as the use of biological therapy (RR = 0.77; 95% CI 0.69-0.86), use of DMARDs (RR = 0.71; 95% CI 0.62-0.82) and number of rheumatology consultations (RR = 0.97; 95% CI 0.92-1.02) in comparison with the centralized care model (RR = 2.32; 95% CI 1.58-3.35). Due to the biases between the groups due to the non-probability sampling, a PSM was performed, with a 1: 1 match, caliper of 0.065, obtaining a pseudo population with well-balanced covariates (see table 1). In the common support area, statistically significant differences were documented in sustained remission over 2 years, in favor of the centralized care group 45 vs 17.9% (p = 0.001).Conclusion:With the information from the clinical records, statistical strategies can be used to evaluate important differences in centralized care programs, observing favorable results of these types of care that are not related to isolated elements of the program, but to the overall effect of the program.References:[1]Austin PC.

Abstract
The mechanisms of rotavirus entry into the target cell are described as a multi-step event in which the virions are bound to sialic acid (SA), followed by interaction with heat shock cognate protein 70 (Hsc70), some integrins and protein disulfide isomerase (PDI). However, the cell surface receptor molecules facilitating the entry of tumor cell-adapted rotavirus are not completely characterized. Using infection blocking assays with antibodies to some heat shock proteins (HSPs) and also some inhibitors of these cellular proteins, we were able to identify the cell surface Hsp90, Hsp70, Hsc70, Hsp60, Hsp40, PDI and integrin β3 as receptors of tumor cell-adapted rotavirus in Reh cells. Furthermore, the results also indicated that these rotavirus receptors are associated with lipid microdomains (rafts). Our findings provide evidence that rotavirus tropism for these human acute lymphocytic leukemia cells is explained by the relatively high expression of some HSPs in rafts. The results shown here encourage further research aim at evaluating the potential use of rotaviruses as an oncolytic agent for the treatment of some cancers. Keywords: heat shock proteins; rotavirus; cell receptor; cancer; oncolytic virus.

Abstract
Abstract
Introduction/Objective
Placental site nodules (PSNs) are rare intermediate trophoblastic lesions characterized by hyalinized cellular aggregates that are small, well-circumscribed, non-necrotic, and paucicellular. PSNs are generally incidental in gynecologic specimens. ETTs are malignant proliferations of intermediate trophoblasts and are generally larger, with nuclear atypia, and higher mitotic rate. Atypical placental site nodules (APSNs) are histologically intermediate between PSN and ETT and not well characterized in the literature to date. There exists room for more objective characterization of PSN and APSN. We use objective measurements to characterize trophoblastic proliferations based on size, location, mitotic rate, number of trophoblasts per high-power field (t-HPF), ki-67 index, beta-hCG, time since last pregnancy, presence of calcification or necrosis, and clinical follow-up.
Methods
The surgical pathology database of a single large academic institution was searched for cases of “placental site nodule,” “atypical placental site nodule,” “epithelioid trophoblastic tumor,” and “placental site trophoblastic tumor”. Clinical and morphologic data were recorded for each case. Ki-67/cytokeratin AE1/AE3 dual immunohistochemical stains were performed to assess the proliferative index of the trophoblastic cells.
Results
70 cases of trophoblastic lesions (53 PSN, 4 APSN, 5 ETT, 8 PSTT) were identified. Results include: PSNs were on average 3.2 mm, 56.5 t-HPF, and 2.6% ki-67. APSNs 4.3 mm, 97.8 t-HPF, and 6.4% ki-67. ETTs 16.5 mm, 161.8 t-HPF, and 12.2% ki-67.
Conclusion
Objective measurements of trophoblastic lesions, as well as correlation with clinical data, may be useful for more accurate classification of these lesions, especially by those who encounter them rarely. To date, the clinical risk, optimal management, and risk for progression of APSNs are not well characterized and thus are worthy of additional study and description. For example, in our data, 14 cases originally signed out at PSN were at least 4 mm, which may re-classify them as APSN.

Abstract
Abstract
A 78-year-old man with a history of hypertension and diabetes mellitus was referred to the ER of our hospital due to an episode of shortness of breath of new onset, associated with dizziness and central thoracic pain of 5 minutes duration. Significant physical examination findings included a V/VI holosystolic murmur at fourth intercostal space with radiation to the axilla. ECG showed no significant abnormalities and cardiac enzymes were within normal ranges The TTE and 3D TOE showed dilated left atrial with normal ventricular size and function with an isolated cleft posterior mitral valve leaflet that bisected into two separate leaflets of identical morphology. Concomitant posterolateral leaflet prolapse was also present with two eccentric, posteriorly, and interatrial septum directed regurgitant jets visualized with colour flow Doppler.
Cleft mitral valve leaflet (CMVL) is an uncommon congenital cause of mitral regurgitation. Clefts are slit-like holes or defects hypothesized to be a result of incomplete expression of an endocardial cushion defect and most commonly involve the anterior mitral valve leaflet with a paediatric incidence of 1:1340. Clefts affecting only the posterior mitral valve leaflet are extremely rare . Important co-existing anomalies with either posterior and/or anterior CMVL include counterclockwise rotation of the papillary muscles, the presence of an accessory papillary muscle or mitral valve leaflet, atrial septal defects, and mitral valve prolapse. Acquired causes of clefts include infective endocarditis or trauma from surgical exploration.
Regurgitation in CMVL results from blood flow directly through the cleft itself or from malcoaptation from accessory chordae with or without papillary muscle distortion. Early detection through 3D TEE echocardiography can provide accurate anatomical images of the mitral valve structure and identify associated congenital anomalies.
Conclusion
Posterior CMVL is an extremely rare cause of mitral insufficiency. 3D TEE early recognition of this rare clinical entity and co-existent anomalies can identify afflicted patients who can be closely monitored for the progression of symptoms as well as ventricular dysfunction. 3D TEE permits a personalized medicine tailoring the medical treatment to the individual characteristics of each patient.

Abstract
We report a 71 year-old female with a history of rheumatic valvulopathy, who underwent St. Jude 23 and St. Jude 21 in mitral and aortic position replacement.
The patient was admitted to the ER for pulmonary edema with haemoglobin level of 7.7 g/dL .No evidence of gastrointestinal bleeding. She was assessed to exclude intravascular hemolysis: bilirrubin 3.1mg/d,L direct bilirrubin 1.0 mg/dL, reticulocytes 207.000/mcL 6.8%, LDH 1.213, free plasmatic haemoglobin 9.6mg/dL, haptoglobin < 1 mg/dL, negative direct and indirect Coombs.
Upon suspicion of hemolytic anemia in relation to prosthetic dysfunction, TEE was performed revealing stenotic mechanical aortic prosthesis with abundant pannus and normofunctional mitral prosthesis, no leakages were observed. A coronary CT scan showed severe calcification of the aortic root and mitral annulus without evidence of redundant tissue than hindered the opening of the aortic or mitral valves. Cardiac catheterization revealed normal coronary arteries, cardiac output preserved and mild passive predominance of PAP. Heart Team decided on aortic prosthesis valve replacement.
On March 22, 2019 surgery was performed. There was a heavily calcified ascending aorta and aortic root with abundant pannus at the ventricular aspect of the aortic prosthesis. Former aortic prosthesis was resected and the root reconstructed with a pericardial patch. 18-mmATS mechanical aortic prosthesis was implanted. After 127minutes of cross-clamping time, the patient was admitted to the ICU. She presented a torpid course in the postoperative period after cardiac surgery and cardiogenic shock ensued.
TEE was repeated, showing pseudoaneurysm of the mitral–aortic intervalvular fibrosa, left atrium dissection and severe paraprosthetic aortic leakage. Coronary CT scan revealed a large cavity, 7x4x3.5 cm, extending posteriorly and displacing cranially the right pulmonary artery and subsequently rejecting the cavity of left atrium; with final diagnosis of aorto-left atrial fistula with left atrium dissection. Emergent surgery was decided. During the procedure, mitral–aortic intervalvular fibrosa pseudoaneurysm was confirmed, perforation from the subaortic left ventricle into the left atrium was also appreciated at the junction of the aortic root pericardial patch with the dissected left atrium wall. Surgery was complicated with hemorrhagic shock and massive uncontrolled bleeding with severe coagulopathy and thrombocytopenia. The patient went into cardiac arrest and passed away in the operating room.
Conclusion
Aorto atrial fistulas are rare but important complications of many disease processes of the aorta and aortic valve. Classical clinical signs of continuous murmurs may not be present and echocardiography forms the cornerstone of diagnosis. AAF should be suspected in patients with poorly controlled heart failure and prior aortic surgery. Prompt surgical repair is usually helpful in relieving symptoms and decreasing mortality.

Abstract
We report a 43 year-old female with a past TTE echocardiography of rheumatic valve disease performed in her district hospital , ( No clear symptomatology of rheumatic fever in the past). She was transferred to our tertiary hospital for elective cardiac surgery.
Preoperative echocardiogram showed a non-dilated left ventricle with preserved contractility, mild-moderate left atrium enlargement with severe mitral regurgitation and basal displacement of papillary muscles and severe tricuspid regurgitation.All of it resembling a hammock mitral valve instead of former echocardiogram described as rheumatic valve disease.
Preoperative cardiac study showed severe pulmonary hypertension with increased pulmonary vascular resistances. Preserved biventricular cardiac output and increased proto and telesystolic pressures.
During surgery , ifindings were described as a mitral valve with a large papillary muscle inserted in the distal third of the left ventricle with none tendinous cords at the anterior leaflet and without cords in the posterior leaflet with an isolated papillary muscle with cords at A3 and P3 scallops, compatible with hammock mitral valve. A tendinous muscle/fibrous or fibromuscular band connecting the septum to the posterior wall of the left ventricle was described. Moreover over, there was an enlarged tricuspid ring with very short tendinous cords on the septal leaflet, although the leaflet was bigger than usual.
Surgery consisted of resection of the mitral valve preserving A3 and P3 scallops with a 29mm Bicarbon Sorin mechanical mitral prosthesis and a 32mm Carpentier tricuspid ring implantation and pulmonary veins ablation combined with occlusion of left atrial appendage. After 112 minutes of cross-clamping time, the patient was weaned from cardiopulmonary bypass. She had important left ventricle dysfunction which improved with dobutamine and AAI pacemaker at 90lpm. Postoperative TEE showed moderate dysfunction of right ventricle, mild left ventricular dysfunction, moderate tricuspid regurgitation and a good functioning of the prosthesis. TTE before discharge showed good function of mitral valve prosthesis, good left ventricle function, mild tricuspid regurgitation, mild-moderate right ventricular enlargement, although less than preoperatively.
Conclusion
Congenital mitral valulophaty is a rare condition in the adulthood. The estimated prevalence is 0,5%. The hammock mitral valve is a more uncommon pathology which affects the mitral valve and subvalvular apparatus. This anomaly, was first described in 1967 and it is characterised by anomalous papillary muscles directly connected to the anterior mitral valve by a fibrous bridge without chordae tendineae in between them. This fibrous bridge hampers the opening and closure of the mitral valve.
Diagnosis requires a high index of suspicion, both ultrasound studies and medical history, to avoid misdiagnosis.

Abstract
A 47-year-old woman presented to the ER with a sudden-onset left side chest pain of less than one hour in duration that started at rest. The pain was severe and radiated to the left shoulder. This was accompanied with symptoms of shortness of breath and sweating but no similar episodes in the past. There was no significant history of coronary artery disease or any other illness in the family. She had dyslipidemia and a smoking habit of 1 pack/day for the previous 10years.
In the ERt, she was hemodynamically stable and her physical examination was within normal limits. ECG showed ST-segment elevation in the inferior leads. No prior ECG was available for comparison. She underwent emergent PCI which showed spontaneous proximal segment circumflex (dominant) artery dissection with TIMI angiographic flow grade 0. All other coronaries were patent with TIMI III flow and no atherosclerotic changes. PCI was carried out, but unfortunately, it was complicated with coronary rupture having to implant a drug eluting stent in order to seal the vessel rupture, with optimal final result (TIMI 3).
An urgent TTE was performed for evaluation of the patient due to persistence of chest pain after coronariography, revealing an echogenic mass at the left atrium suggesting extracardiac hematoma vs. left atrium dissection. TC scan confirmed space compromise of the left atrium by a mass, without being able to rule out active bleeding. The patient was transferred to our center for emergent CABG surgery.
Upon arrival, the patient had persistent chest pain, sinus tachycardia, and hypertension. Intraoperative TOE findings consisted of a mass compromising left atrium and minimal pericardium effusion. Comprehensive study identified a mobile intimal flap of the atrial wall that was creating a false chamber.
Intraoperative surgery findings were compatible with a huge left atrial desiccant hematoma . Two orifices were performed on the epicardium of the inferior and lateral border of the left atrium, in order to drain the retained blood and lavage. No active bleeding was evidenced.
TTE control evidenced disappearance of the left atrium mass a The patient had a satisfactory evolution and discharged without complications.
Even though left atrial desiccant hematoma is a rare STEMI complication , in this patient, we concluded the etiology was iatrogenic due to the performance of PCI.
Conclusion
Left atrial dissection is an uncommon entity. It is generally associated with mitral valve replacement, but other predisposing factors should be considered in pathogenesis. Its diagnosis requires a high index of suspicion.
Predisposing factors and catheterization, surgical or pathologic findings should be reviewed in order to identify the pathogenic mechanism . Dissection of the coronary sinus secondary to retrograde cardioplegia, endocarditis, cardiac rupture after myocardial infarction, blunt chest trauma and iatrogenic PCI are related to its development.

Abstract
OBJECTIVES Trauma is a leading cause of morbidity and mortality worldwide, with a disproportionate burden of illness in low- and middle- income countries. This study sought to provide a proof-of-concept pilot study to evaluate the feasibility of a trauma registry in the Western Honduras Hospital. METHODS A cross-sectional, observation study was performed that included all admitted, transferred, or deceased trauma patients presenting to the Western Honduras Hospital from February 4, 2019 until April 4, 2019. Descriptive statistics were utilized to describe patient demographics and injury characteristics. RESULTS 268 patients were enrolled. The average age was 27.5 years (SD ±21.3). 10% of injuries were due to interpersonal violence. The most common mechanisms of injury were falls (33.6%) and motor vehicle collisions (MVCs) (22.4%). The mean Modified Kampala Trauma Score (M-KTS) was 12 (SD ±1.4). The mortality rate was 1.1% (N = 3). 94.5% of data points were complete. CONCLUSIONS A continuous injury surveillance system in the Western Honduras Hospital is feasible and provides valuable information. The data completeness was suboptimal, but the current data collection system may be improved via modifying and utilizing the registry form as both a clinical and data collection instrument.

Abstract
OBJECTIVES This study aimed to identify factors associated with attempting to quit and successful smoking cessation in a population-based sample of Brazilian smokers. STUDY DESIGN This is a prospective cohort study. METHODS Data came from the first two waves of the International Tobacco Control Brazil Survey, conducted in 2009 and 2012/2013 in three cities: Rio de Janeiro, São Paulo, and Porto Alegre. Data were collected from 488 adults (aged ≥18 years) who smoked at Wave 1 and who were resurveyed at Wave 2. Crude and adjusted relative risks for two outcomes (making a quit attempt between Wave 1 and Wave 2 and successfully quitting by Wave 2) were estimated. Multivariable multilevel logistic regression models were used, whereby variables were added to the models in a series of blocks. RESULTS Nearly two-thirds (65.6%) of smokers attempted to quit between waves, and 23.4% had quit at Wave 2. Intention to quit smoking at Wave 1 was the only variable associated with attempt to quit by Wave 2 (odds ratio [OR] = 2.85; 95% confidence interval [CI] 1.64-4.94; P < 0.001). Smokers of higher socio-economic status (OR high versus low = 1.80; 95% CI 1.05-3.10; P = 0.03) and lower nicotine dependence (OR low Heaviness of Smoking Index [HSI] versus high HSI = 1.94; 95% CI 1.10-3.43; P = 0.02) were more likely to successfully quit. The presence of another adult smoker at home was negatively related to successful quitting (OR = 0.50; 95% CI 0.26-0.94; P = 0.03). CONCLUSIONS These results are generally consistent with prior research and have potential to inform governmental interventions to promote tobacco cessation, particularly among disadvantaged groups.

Abstract
BACKGROUND The management of papillary lesions is controversial with studies showing different rates of upstaging to malignancy. There is a paucity of research into race as an independent risk factor. The aim of this study is to identify if race is correlated with upstaging to malignancy with a secondary focus of analyzing for other personal and tumor specific risk factors for upstaging. METHODS We performed a retrospective review of 123 papillary lesions with univariate analysis to identify risk factors for upstaging. RESULTS The incidence of papillary lesions found on core needle biopsy was 6%. Atypical papillary lesions were most likely to be upstaged to malignancy at a rate of 27.7%. Papillary lesions and papillary lesions with hyperplasia were also upstaged to cancer at a lower rate of 8.3% and 12.5%, respectively. A univariate analysis of all papillary lesions and a separate analysis of atypical lesions demonstrated a higher likelihood of upstage based on BIRADS classification. Race, age, size of tumor and other radiographic features were not associated with an increased risk for upstaging to malignancy. CONCLUSIONS Atypia remains the most significant contributor to the risk of upstaging papillary lesions to malignancy. Our research supports the practice of excising all atypical papillary lesions with selected excision of those without atypia. In our cohort, there was no association between race and risk of upstaging to malignacy.

Abstract
BACKGROUND Studies of early-term birth after demonstrated fetal lung maturity show that respiratory and other outcomes are worse with early-term birth (370-386 weeks) even after demonstrated fetal lung maturity when compared with full-term birth (390-406 weeks). However, these studies included medically indicated births and are therefore potentially limited by confounding by the indication for delivery. Thus, the increase in adverse outcomes might be due to the indication for early-term birth rather than the early-term birth itself. OBJECTIVE We examined the prevalence and risks of adverse neonatal outcomes associated with early-term birth after confirmed fetal lung maturity as compared with full-term birth in the absence of indications for early delivery. STUDY DESIGN This is a secondary analysis of an observational study of births to 115,502 women in 25 hospitals in the United States from 2008 through 2011. Singleton nonanomalous births at 37-40 weeks with no identifiable indication for delivery were included; early-term births after positive fetal lung maturity testing were compared with full-term births. The primary outcome was a composite of death, ventilator for ≥2 days, continuous positive airway pressure, proven sepsis, pneumonia or meningitis, treated hypoglycemia, hyperbilirubinemia (phototherapy), and 5-minute Apgar <7. Logistic regression and propensity score matching (both 1:1 and 1:2) were used. RESULTS In all, 48,137 births met inclusion criteria; the prevalence of fetal lung maturity testing in the absence of medical or obstetric indications for early delivery was 0.52% (n = 249). There were 180 (0.37%) early-term births after confirmed pulmonary maturity and 47,957 full-term births. Women in the former group were more likely to be non-Hispanic white, smoke, have received antenatal steroids, have induction, and have a cesarean. Risks of the composite (16.1% vs 5.4%; adjusted odds ratio, 3.2; 95% confidence interval, 2.1-4.8 from logistic regression) were more frequent with elective early-term birth. Propensity scores matching confirmed the increased primary composite in elective early-term births: adjusted odds ratios, 4.3 (95% confidence interval, 1.8-10.5) for 1:1 and 3.5 (95% confidence interval, 1.8-6.5) for 1:2 matching. Among components of the primary outcome, CPAP use and hyperbilirubinemia requiring phototherapy were significantly increased. Transient tachypnea of the newborn, neonatal intensive care unit admission, and prolonged neonatal intensive care unit stay (>2 days) were also increased with early-term birth. CONCLUSION Even with confirmed pulmonary maturity, early-term birth in the absence of medical or obstetric indications is associated with worse neonatal respiratory and hepatic outcomes compared with full-term birth, suggesting relative immaturity of these organ systems in early-term births.

Abstract
IntroductionDepression is a disease with high prevalence all over the world. Selective serotonine reuptake inhibitors (SSRIs) and dual antidepressants (DA) are worldwide used to treat the different types of depressive episodes. Between the adverse events of these compounds, an unusual but potentially severe side effect is the syndrome of inapropriate antidiuretic hormone secretion (SIADH).Results and discussionSeveral cases published, and an amount of cases series have documented the association of SIADH to the use of SSRIs and DA. All SSRIs and DA are at risk of producing SIADH (fluoxetine, paroxetine, fluvoxamine, sertraline, citalopram, escitalopram, venlafaxine and duloxetine). Old age has been found as a risk factor for developing SIADH. There are not enough data to conclude that other risk factors can play a role in the development of this adverse event. Treatment should include the immediate withdrawal of the antidepressant. The introduction of other antidepressants is controversial, as SIADH has been related with all antidepressive treatments; but the risk of relapse into a depressive episode must be considered also. Between symptomatic treatments, the control of water intake and the use of low doses of loop diuretics can be recommended. Severe cases can be treated with higher doses of loop diuretics and saline hypertonic solution.ConclusionsSIADH has been related with SSRIs and DA antidepressants and it is an infrequent but severe adverse event. Its risk must be considered when prescribing treatment with them. If this adverse event is produced, the substitution of the antidepressant should be done.Disclosure of interestThe authors have not supplied their declaration of competing interest.
