Helicobacter pylori cagA, vacA, iceA and babA Genotypes from Peruvian Patients with Gastric Intestinal Metaplasia.

We explored the clinical-stage association of gastric intestinal metaplasia (IM) compared to cases of chronic non-atrophic gastritis (CNAG) and its relationship with virulence genotypes of Helicobacter pylori (H. pylori) clinical isolates from patients with dyspepsia in Peru. This study was cross-sectional and included 158 H. pylori clinical isolates; each isolate corresponded to a different Peruvian patient, genotyped by polymerase chain reaction to detect cagA gene and EPIYA motifs, the vacA gene (alleles s1, s2, i1, i2, d1, d2, m1, m2 and subtypes s1a, s1b and s1c), the iceA gene (alleles 1 and 2), and the babA gene (allele 2). We observed that 38.6% presented with IM and that all clinical isolates were CagA positive. The EPIYA-ABC motif was predominant (68.4%), and we observed a high frequency for the vacA gene alleles s1 (94.9%), m1 (81.7%), i1 (63.9%), and d1 (70.9%). Strains with both iceA alleles were also detected (69.6%) and 52.2% were babA2 positive. In addition, it was observed that the cagA+/vacAs1m1 (PR: 2.42, 1.14 to 5.13, p < 0.05) and cagA+/vacAs1am1 (PR: 1.67, 1.13 to 2.45, p < 0.01) genotypes were associated with IM. Our findings revealed the cagA and vacA risk genotypes predominance, and we provided clinically relevant associations between Peruvian patients with H. pylori infection and IM clinical stage.

Humor-Based Messaging in Testicular Cancer Awareness Campaigns: A Comparative Critical Review.

Extensive research showcases the extent and efficacy of humor-based messaging in general health promotion. However, the work describing humor's use within testicular cancer (TC) awareness is less developed. The aim of this comparative critical review was to determine the impact of using humor-based messaging in TC awareness campaigns to achieve a baseline assessment from which future research can be modeled. A literature search was conducted using seven databases to locate relevant literature. Three research questions guided this investigation: (1) To what extent has humor been used in TC awareness campaigns? (2) What does the literature reveal about the use of humor-based messaging on relevant health outcomes? (3) What are the limitations within current TC awareness strategies? Six studies were included in the review, of which three directly assessed the use of humor in TC awareness vis-à-vis intervention designs. Humor-based strategies were implemented to enhance knowledge of TC and testicular self-examination (TSE) procedures, reduce anxiety surrounding detection threat, and promote TSE. The rhetoric provided to men via various health interventions relied on humor and slang to promote TSE among males. Despite the small sample size of the included studies, this review determined that humor may be useful in reducing uncomfortable feelings surrounding TSE, increasing awareness of TC, and promoting TSE. When using humor-based messaging, however, the audience and type of humor implemented must be considered. Limited research exists assessing the long-term impact humor in TC promotion on health behavioral changes, easing anxieties related to detection, and increased self-efficacy surrounding TSE.

Contributing factors for self-reported HIV in male Peruvian inmates: results of the 2016 prison census.

Introduction: Worldwide, prisons are high-risk settings for the transmission of infectious diseases such as HIV. There is a need to understand the health conditions of prisoners to improve and implement timely strategies for HIV diagnosis and control. Hence, we aimed to identify factors associated with self-reported HIV (srHIV) among Peruvian inmates. Methods: This study is a secondary data analysis of the First Peruvian Prison Census conducted in 2016. We estimated the prevalence of srHIV in prisoners who were male at birth and the association of srHIV with other social conditions, criminal records, and prevalent health conditions. Nested models identified a multivariable parsimonious model for factors associated with srHIV and yielding prevalence ratios adjusted by the included parameters. Results: The census surveyed 71,087 male inmates of whom 0.4% reported srHIV (n = 305), and 82% of whom were receiving antiretroviral treatment (n = 220). In our final multivariable model, srHIV was independently associated with age between 36 and 55 years old vs. >55 years old [parsimonious prevalence ratio (pPR) = 1.98, 95% CI, 0.96-4.08], having a stable partner out of prison (pPR = 1.64, 95% CI, 1.24-2.19), being homosexual (pPR = 4.16, 95% CI, 2.50-6.90), self-report of prevalent tuberculosis co-infection (pPR = 2.55, 95% CI, 1.82-3.58), self-report of prevalent sexually transmitted infections (pPR = 34.49, 95% CI, 24.94-47.70), and self-report of prevalent illicit drug use 30 days before the survey (pPR = 1.91, 95% CI, 1.43-2.56). Conclusion: Self-reported HIV is associated with multiple social, health and prison risks among Peruvian inmates. Deeply understanding these factors would help to design HIV prevention and control strategies in Peruvian prisons.

Mortalidad atribuible al consumo de tabaco en la Provincia de Buenos Aires. Estimación a partir de las Encuestas Nacionales de Factores de Riesgo / Mortality Attributable to Tobacco Consumption in the Province of Buenos Aires. Estimation from the National Surveys of Risk Factors

RESUMEN Introducción : El consumo de tabaco es la principal causa de defunción por enfermedades no transmisibles como las cardiopatías, las neumopatías y el cáncer. Estimar la mortalidad atribuida al consumo de tabaco dependiente de su prevalencia se basa en el conocimiento previo del número de fumadores, exfumadores y no fumadores en la población. Estos datos provienen de las cuatro Encuestas Nacionales de Factores de Riesgo (ENFR). Objetivos : El presente trabajo pretende mostrar la carga de mortalidad por consumo de tabaco en la Provincia de Buenos Aires en los períodos de relevamiento de las cuatro ENFR (2005-2009-2013-2018). Material y métodos : La mortalidad atribuible fue calculada utilizando un método dependiente de la prevalencia, y asumiendo los riesgos asociados al consumo en las 19 causas clasificadas como asociadas al tabaquismo según el estudio Cancer Prevention Study II (CPSII). Las defunciones fueron agrupadas en períodos equivalentes a los relevamientos de cada ENFR. Las fracciones atribuibles del CSPII se aplicaron entonces calculando las defunciones absolutas y atribuibles de mortalidad por causa y sus agrupamientos: tumores, circulatorias y respiratorias. Resultados : Globalmente, para todas las edades de 18 años y más, se pasó de una prevalencia de tabaquismo del 29,5% en 2005 al 23,1% en 2018 (reducción absoluta de 6,4% y porcentual del 21,7%). De las 18 255 muertes producidas por enfermedades cardiovasculares coincidentes con los cuatro relevamientos, 6293 fueron atribuibles al tabaquismo (34,4%), frente al 68% de las muertes por tumores y el 40% de las muertes de causa respiratoria. Conclusión : Se hace necesario fortalecer aún medidas para reducir la exposición al tabaco.

ABSTRACT Background : Tobacco consumption is the leading cause of death from non-communicable diseases, such as heart disease, lung disease and cancer. Estimating prevalence-based mortality attributed to tobacco consumption is based on prior knowledge of the number of smokers, ex-smokers, and non-smokers in the population. These data derive from the four National Surveys of Risk Factors (Encuestas Nacionales de Factores de Riesgo, ENFR). Objectives : This study aims to show the burden of mortality due to tobacco consumption in the Province of Buenos Aires in the assessed periods of the four ENFRs (2005, 2009, 2013, 2018). Methods : Mortality attributable to tobacco consumption was estimated by using a prevalence-based method and assuming the risks associated with smoking in the 19 causes classified as associated with smoking, in accordance with the Cancer Prevention Study II (CPSII). The deaths were grouped into periods equivalent to those relevant to each ENFR. The CSPII attributable fractions were then applied by estimating the absolute deaths and attributable fractions of mortality by cause and groupings: tumours, circulatory diseases and respiratory diseases. Results : Overall, in persons aged 18 years or older, there was a decrease in smoking prevalence from 29.5% in 2005 to 23.1% in 2018 (an absolute reduction of 6.4% and a percentage reduction of 21.7%). A total of 6293 out of 18 255 deaths from cardiovascular diseases in the four surveys were attributed to smoking, that is, 34.4%, compared to 68% of deaths from tumours and 40.0% of deaths from respiratory diseases. Conclusion : It is necessary to further strengthen measures to reduce exposure to tobacco.

Online adaptive radiotherapy: Assessment of planning technique and its impact on longitudinal plan quality robustness in pancreatic cancer.

BACKGROUND AND PURPOSE: Planning on a static dataset that reflects the simulation day anatomy is routine for SBRT. We hypothesize the quality of on-table adaptive plans is similar to the baseline plan when delivering stereotactic MR-guided adaptive radiotherapy (SMART) for pancreatic cancer (PCa). MATERIALS AND METHODS: Sixty-seven inoperable PCa patients were prescribed 50 Gy/5-fraction SMART. Baseline planning included: 3-5 mm gastrointestinal (GI) PRV, 50 Gy optimization target (PTVopt) based on GI PRV, conformality rings, and contracted GTV to guide the hotspot. For each adaptation, GI anatomy was re-contoured, followed by re-optimization. Plan quality was evaluated for target coverage (TC = PTVopt V100%/volume), PTV D90% and D80%, homogeneity index (HI = PTVopt D2%/D98%), prescription isodose/target volume (PITV), low-dose conformity (D2cm = maximum dose at 2 cm from PTVopt/Rx dose), and gradient index (R50%=50% Rx isodose volume/PTVopt volume).A novel global planning metric, termed the Pancreas Adaptive Radiotherapy Score (PARTS), was developed and implemented based on GI OAR sparing, PTV/GTV coverage, and conformality. Adaptive robustness (baseline to fraction 1) and stability (difference between two fractions with highest GI PRV variation) were quantified. RESULTS: OAR constraints were met on all baseline (n = 67) and adaptive (n = 318) plans. Coverage for baseline/adaptive plans was mean ± SD at 44.9 ± 5.8 Gy/44.3 ± 5.5 Gy (PTV D80%), 50.1 ± 4.2 Gy/49.1 ± 4.7 Gy (PTVopt D80%), and 80%±18%/74%±18% (TC), respectively. Mean homogeneity and conformality for baseline/adaptive plans were 0.87 ± 0.25/0.81 ± 0.30 (PITV), 3.81 ± 1.87/3.87 ± 2.0 (R50%), 1.53 ± 0.23/1.55 ± 0.23 (HI), and 58%±7%/59%±7% (D2cm), respectively. PARTS was found to be a sensitive metric due to its additive influence of geometry changes on PARTS' sub-metrics. There were no statistical differences (p > 0.05) for stability, except for PARTS (p = 0.04, median difference -0.6%). Statistical differences for robustness when significant were small for most metrics (<2.0% median). Median adaptive re-optimizations were 2. CONCLUSION: We describe a 5-fraction ablative SMART planning approach for PCa that is robust and stable during on-table adaption, due to gradients controlled by a GI PRV technique and the use of rings. These findings are noteworthy given that daily interfraction anatomic GI OAR differences are routine, thus necessitating on-table adaptation. This work supports feasibility towards utilizing a patient-independent, template on-table adaptive approach.

When tissue is not the only issue: Poorly differentiated lung squamous-cell carcinoma with adrenal, costochondral, and cardiac metastases - case report.

Nonmelanoma skin cancer is the most common cancer in the world, and lung cancer is the leading cause of death from cancer. Histologically, squamous cell carcinoma (SCC) is the second most prevalent type of both skin and lung cancers. We report the case of a 38-year-old female with metastatic, poorly differentiated lung SCC detected on chest X-ray after she presented to the hospital with cough and dyspnea. She had had a 7.5 cm moderately differentiated well-circumscribed posterior scalp SCC completely excised eight years earlier. CT scan showed a large right lung mass, nodular filling defect in the left atrium (LA), and metastases to the adrenal glands and the first rib. Her pulmonary tumor extends to the LA via the right superior pulmonary vein, which is rarely reported in the literature. Ultrasound-guided biopsy of the rib mass showed poorly differentiated SCC. The patient received urgent radiotherapy, given superior vena cava and mainstem bronchus compression. Head CT showed no brain metastasis. A biopsy of the left adrenal initially reported an undifferentiated pleomorphic sarcoma; however, a second pathologist reported it as a poorly differentiated carcinoma of lung origin. At least three pathologists verified the specimen, and it had a PD-L1 test with a 1-49% score. An initial echocardiogram confirmed the LA mass. The patient received a Paclitaxel-Carboplatin-Pembrolizumab regimen as the first-line treatment for metastatic SCC. A repeat echocardiogram after cycle 1 showed a decrease in the size of the tumor in the LA. Almost five months after her initial visit, this young woman's symptoms and performance status have improved post-palliative radiotherapy and chemo-immunotherapy. Follow-up CT showed smaller lung, nodal, adrenal, and costochondral masses, and evidence of necrosis. This case is clinically relevant because it represents a common problem presenting uncommonly. Moreover, it highlights that ultrasound-guided interventions and medical imaging are essential in directing metastatic cancer diagnosis, treatment, and follow-up, especially when pathology cannot confirm but only presume a specific diagnosis.

Anxiety symptoms and anxiety sensitivity in relation to cigarette dependence, perceived barriers for smoking cessation and quit problems among adult Latinx smokers.

Cigarette smoking is associated with adverse physical and mental health among Latinx adults in the United States. The present investigation sought to explore the main and interactive effects of anxiety symptoms and anxiety sensitivity in relation to cigarette dependence, perceived barriers for smoking cessation, and severity of problems experienced when quitting among adult Latinx smokers. Participants included 338 Latinx adult daily cigarette smokers (Mage = 35.53 years; SD = 8.65; age range 18-61; 37.3% female). Results indicated that anxiety symptoms were associated with greater cigarette dependence, severity of problems when quitting, and perceived barriers for smoking cessation (effect size range: 2%-3% of variance), whereas anxiety sensitivity was related to severity of problems when quitting and perceived barriers for smoking cessation (effect size range: 2%-3% of variance). There was also a statistically significant interaction between anxiety sensitivity and anxiety symptoms for cigarette dependence; anxiety was related to cigarette dependence for Latinx smokers with higher levels of anxiety sensitivity, but not for those with lower levels of anxiety sensitivity. Overall, the present findings indicate that anxiety symptoms and anxiety sensitivity are relevant factors for better understanding cigarette dependence, problems experienced when trying to quit, and perceptions of barriers to quitting among adult Latinx smokers.

Anxiety-related constructs and smoking outcome expectancies among Latinx smokers.

Hispanic/Latinx (hereafter Latinx) smokers in the United States (US) experience unique smoking cessation-related challenges. Smoking outcome expectancies (i.e., positive and negative beliefs about the consequences of smoking behavior) have been linked to the maintenance of smoking and comorbidity with negative emotional states such as anxiety among Latinx smokers. However, past work has not characterized rates of probable anxiety disorder and elevated levels of anxiety sensitivity among English-speaking daily Latinx smokers from the United States or concurrently evaluated the explanatory relevance of anxiety symptoms and anxiety sensitivity for negative and positive smoking outcome expectancies. The present investigation sought to (a) determine the base rate of probable anxiety disorder and elevated anxiety sensitivity and (b) explore the unique roles of anxiety symptoms and anxiety sensitivity in relation to negative and positive smoking outcome expectancies. Participants included 338 English-speaking Latinx adult daily cigarette smokers from the United States (Mage = 35.53 years; SD = 8.65; age range 18-61; 37.3% female). Findings revealed high rates of probable anxiety disorder (50.9%) and elevated anxiety sensitivity (73.4%) among English-speaking Latinx smokers from the United States. Anxiety sensitivity, but not anxiety symptoms or disorders, was significantly related to negative consequences, negative reinforcement, positive reinforcement, and appetite/weight control smoking outcome expectancies. Overall, anxiety experiences were common among Latinx smokers, and anxiety sensitivity was a relatively more consistent and robust predictor of negative and positive outcome expectancies relative to anxiety symptoms and probable anxiety disorder.

Antibody Banding Patterns on the Enzyme-Linked Immunoelectrotransfer Blot (EITB) Assay Clearly Discriminate Viable Cysticercosis in Naturally Infected Pigs.

Enzyme-linked immunoelectrotransfer blot (EITB) detects antibodies against seven Taenia solium larvae antigens in three protein families (GP50, T24/42, and 8-kDa) with different structures and functions. EITB banding patterns against these antigens in pigs provide information about the course of infection and may discriminate viable cysticercosis. We analyzed the banding patterns and infection outcomes (presence of viable cysts, degenerated cysts, and any cysts) of 512 rural pigs. Banding patterns were grouped into homogenous classes using latent class analysis, and relationships with infection outcomes were assessed. Four classes were identified: 1 (n = 308, EITB-negative or positive for the GP50 family), 2 (n = 127, positive for GP50 (GP50 family), GP42-39 and GP24 (T24/42 family), but negative for 8-kDa antigens), 3 (n = 22, positive for GP50 and T24/42 antigens (GP42-39 and GP24), as well as to 8-kDa bands GP13, GP14, and GP18, but negative for GP21), and 4 (n = 55, positive for GP50 and T24/42 antigens, as well as to 8-kDa antigens GP21 and GP18 in combination). Pigs in classes 3 and 4 were more likely to have viable cysts (72.6% and 96.4%, respectively) than pigs in classes 1 and 2 (0.7% and 27.6%, respectively; p < 0.001). The number of infections with any cysts was higher in classes 3 and 4 (77.3% and 98.2%, respectively) and lower in classes 2 and 1 (34.7% and 4.9%, respectively; p < 0.001). Pigs with viable cysts represented >90% of pigs with any cysts in classes 3 and 4 (94.1% and 98.2%, respectively), while degenerated cysts were frequent among pigs with any cysts in classes 1, 3, and 2 (86.7%, 47.1%, and 43.2%, respectively; p < 0.001). EITB banding patterns strongly correlate with cysticercosis infection status in rural pigs, with classes 3 and 4 being more predictive of viable infections.

Clinical and histopathological features of bladder cancer following radiotherapy for prostate cancer: A comparative study.

INTRODUCTION: Low certainty exists on how bladder cancer (BCa) after pelvic radiotherapy (RT) differs from BCa in radiation-naive patients from a histopathological and clinical perspective. This study aims to compare histopathological features of bladder tumors between patients with previous RT for prostate cancer (PCa) and radiation-naive patients using single-institutional data and to estimate relapse-free survival (eRFS) and cystectomy-free survival (eCFS) in both groups. MATERIALS AND METHODS: Comparative study in adult men diagnosed with BCa in Hospital Italiano de Buenos Aires, Argentina, between January 2015 and December 2020. Included patients were categorized as previously irradiated for PCa or radiation-naive. PRIMARY OUTCOME: differences in prevalence of aggressiveness features of bladder tumors (variant histology; high-grade tumors; muscle-invasive disease; criteria compliance for high or very-high risk of progression) between irradiated and radiation-naive patients at diagnosis of BCa. SECONDARY OUTCOMES: differences in eRFS and eCFS between groups. RESULTS: In total, 34 and 291 patients were included in the Irradiated and Radiation-naive groups, respectively. Mean age at the time of diagnosis of BCa was 72.7 years (CI 95% 71.6-73.8). Median follow-up of the overall cohort was 25 months (IQR 11-45.5). Concerning primary outcomes, no statistical differences were found except for a higher prevalence of low-grade tumors between irradiated patients and high-grade tumors between radiation-naive patients (P 0.018). Regarding secondary outcomes, prior RT did not increase neither eRFS nor eCFS in both univariate and multivariate analysis. CONCLUSIONS: BCa after RT for PCa has similar histological features and cystectomy free-survival compared to BCa in a radiation-naive population. For patients with non-muscle invasive BCa arising after prostate RT, the risk of recurrences appears to be similar to non-irradiated patients.

Systemic proliferative arteriopathy and hypophysitis in a cow with chronic ovine herpesvirus 2-induced malignant catarrhal fever.

Malignant catarrhal fever (MCF) is a severe, systemic, lymphoproliferative disease affecting domestic ruminants, caused by a group of MCF viruses in the genus Macavirus. Infection of cattle and bison with ovine herpesvirus 2 (OvHV2) is economically significant in North America. Sheep are the reservoir host of the virus, and only rarely manifest disease. Cattle and bison, however, frequently have lymphoproliferation, mucosal ulceration, and systemic vasculitis. OvHV2-induced MCF in cattle and bison is often fatal, with clinical recovery reported only rarely. Chronic cases are uncommon, but vascular changes of variable severity and ocular lesions have been described. Here we present a case of chronic MCF in a cow with proliferative arteriopathy, systemic vasculitis, and OvHV2-associated hypophysitis. We demonstrated OvHV2 nucleic acid in affected tissues with in situ hybridization.

Glycosylation of Epigallocatechin Gallate by Engineered Glycoside Hydrolases from Talaromyces amestolkiae: Potential Antiproliferative and Neuroprotective Effect of These Molecules.

Glycoside hydrolases (GHs) are enzymes that hydrolyze glycosidic bonds, but some of them can also catalyze the synthesis of glycosides by transglycosylation. However, the yields of this reaction are generally low since the glycosides formed end up being hydrolyzed by these same enzymes. For this reason, mutagenic variants with null or drastically reduced hydrolytic activity have been developed, thus enhancing their synthetic ability. Two mutagenic variants, a glycosynthase engineered from a ß-glucosidase (BGL-1-E521G) and a thioglycoligase from a ß-xylosidase (BxTW1-E495A), both from the ascomycete Talaromyces amestolkiae, were used to synthesize three novel epigallocatechin gallate (EGCG) glycosides. EGCG is a phenolic compound from green tea known for its antioxidant effects and therapeutic benefits, whose glycosylation could increase its bioavailability and improve its bioactive properties. The glycosynthase BGL-1-E521G produced a ß-glucoside and a ß-sophoroside of EGCG, while the thioglycoligase BxTW1-E495A formed the ß-xyloside of EGCG. Glycosylation occurred in the 5″ and 4″ positions of EGCG, respectively. In this work, the reaction conditions for glycosides' production were optimized, achieving around 90% conversion of EGCG with BGL-1-E521G and 60% with BxTW1-E495A. The glycosylation of EGCG caused a slight loss of its antioxidant capacity but notably increased its solubility (between 23 and 44 times) and, in the case of glucoside, also improved its thermal stability. All three glycosides showed better antiproliferative properties on breast adenocarcinoma cell line MDA-MB-231 than EGCG, and the glucosylated and sophorylated derivatives induced higher neuroprotection, increasing the viability of SH-S5Y5 neurons exposed to okadaic acid.

New Antioxidant Active Packaging Films Based on Yeast Cell Wall and Naphtho-γ-Pyrone Extract.

The main objective of this work is the development of new active films based on yeast cell wall obtained by high-pressure homogenization (YCW-H) supplemented with naphtho-γ-pyrone (CL-NGP) extract, which is a bioactive compound produced by Aspergillus tubingensis G131 with great antioxidant potential. A complete characterization of the functional properties of the bioactive films, such as their structural, colour, thermal, mechanical, hydration and water vapour transport, was carried out to evaluate the influence of the addition of the antioxidant compounds. Likewise, the antioxidant capacity of the developed materials and the specific migration of NGPs in food simulants were evaluated. The results showed that CL-NGP extract possessed an important antioxidant activity, which was maintained after incorporation in YCW-H films. The addition of 2 and 5% CL-NGPs decreased the hydration of films and consequently improved the water vapour barrier properties. It was observed that CL-NGPs migrate in fatty food simulants and retain their antioxidant capacity in the simulant. The results obtained in this work showed that bioactive films based on yeast cell walls with the addition of CL-NGPs have the potential to be used as packaging material in systems of interest in the food industry.

Improved Diagnosis of Viable Parenchymal Neurocysticercosis by Combining Antibody Banding Patterns on Enzyme-Linked Immunoelectrotransfer Blot (EITB) with Antigen Enzyme-Linked Immunosorbent Assay (ELISA).

The diagnosis of neurocysticercosis (NCC) depends on neuroimaging and serological confirmation. While antibody detection by enzyme-linked immunoelectrotransfer blot (EITB) fails to predict viable NCC, EITB banding patterns provide information about the host's infection course. Adding antigen enzyme-linked immunosorbent assay (Ag-ELISA) results to EITB banding patterns may improve their ability to predict or rule out of viable NCC. We assessed whether combining EITB banding patterns with Ag-ELISA improves discrimination of viable infection in imaging-confirmed parenchymal NCC. EITB banding patterns were grouped into classes using latent class analysis. True-positive and false-negative Ag-ELISA results in each class were compared using Fisher's exact test. Four classes were identified: 1, EITB negative or positive to GP50 alone (GP50 antigen family); 2, positive to GP42-39 and GP24 (T24/42 family), with or without GP50; and 3 and 4, positive to GP50, GP42-39, and GP24 and reacting to bands in the 8-kDa family. Most cases in classes 3 and 4 had viable NCC (82% and 88%, respectively) compared to classes 2 and 1 (53% and 5%, respectively). Adding positive Ag-ELISA results to class 2 predicted all viable NCC cases (22/22 [100%]), whereas 11/40 patients (27.5%) Ag-ELISA negative had viable NCC (P < 0.001). Only 1/4 patients (25%) Ag-ELISA positive in class 1 had viable NCC, whereas 1/36 patients (2.8%) Ag-ELISA negative had viable NCC (P = 0.192). In classes 3 and 4, adding Ag-ELISA was not contributory. Combining Ag-ELISA with EITB banding patterns improves discrimination of viable from nonviable NCC, particularly for class 2 responses. Together, these complement neuroimaging more appropriately for the diagnosis of viable NCC.

Anxiety symptoms and smoking outcome expectancies among Spanish-speaking Latinx adult smokers: Exploring the role of anxiety sensitivity.

Although anxiety symptoms/disorders are consistently implicated in smoking processes, no empirical work has identified individual difference factors that may underlie such relations among Latinx smokers. The current study examined anxiety sensitivity as an explanatory factor underlying the relationship between anxiety symptoms and smoking expectancies among Spanish-speaking Latinx smokers. Participants included 363 Spanish-speaking Latinx daily smokers (58.7% female, Mage = 33.3 years, SD = 9.81). Results indicated that anxiety symptoms had a significant indirect effect on positive and negative smoking expectancies through anxiety sensitivity. Such findings suggest that anxiety sensitivity is relevant to understanding the anxiety-smoking expectancies association among Latinx smokers.

Cardiac myxomas: clinical presentation, diagnosis and management.

Cardiac myxomas (CM) are the most common type of primary cardiac tumours in adults, which have an approximate incidence of up to 0.2% in some autopsy series. The purpose of this review is to summarise the literature on CM, including clinical presentation, differential diagnosis, work-up including imaging modalities and histopathology, management, and prognosis. CM are benign neoplasms developed from multipotent mesenchyme and usually present as an undifferentiated atrial mass. They are typically pedunculated and attached at the fossa ovalis, on the left side of the atrial septum. Potentially life-threatening, the presence of CM calls for prompt diagnosis and surgical resection. Infrequently asymptomatic, patients with CM exhibit various manifestations, ranging from influenza-like symptoms, heart failure and stroke, to sudden death. Although non-specific, a classic triad for CM involves constitutional, embolic, and obstructive or cardiac symptoms. CM may be purposefully characterised or incidentally diagnosed on an echocardiogram, CT scan or cardiac MRI, all of which can help to differentiate CM from other differentials. Echocardiogram is the first-line imaging technique; however, it is fallible, potentially resulting in uncommonly situated CM being overlooked. The diagnosis of CM can often be established based on clinical, imaging and histopathology features. Definitive diagnosis requires macroscopic and histopathological assessment, including positivity for endothelial cell markers such as CD31 and CD34. Their prognosis is excellent when treated with prompt surgical resection, with postsurgical survival rates analogous to overall survival in the age-matched general population.
