Gastric Adenoma: A High Incidence Rate of Developing Carcinoma and Risk of Metachronous Gastric Cancer according to Long-Term Follow-Up

Introduction: Gastric adenomas are histologically defined as benign epithelial tumors. While some of them remain adenomas for a long time, others progress to carcinomas. However, long-term outcomes of such cases are not entirely clear. Here, we explored the risk factors and incidence of developing carcinoma from gastric adenoma as well as metachronous gastric cancer. Methods: This study was conducted at a facility that adopted a follow-up strategy for gastric adenoma. Lesions histologically diagnosed as gastric intestinal-type adenomas between January 2004 and December 2016 were analyzed. Clinicopathological data were collected from patients’ medical records, and histological changes from adenoma to carcinoma during endoscopic follow-up and risk factors of cancer development were evaluated. Results: This study involved 409 lesions from 376 patients. The analysis of the development of gastric cancer from adenoma and metachronous gastric cancer was ultimately performed for 282 lesions from 258 patients and 269 lesions from 246 patients, respectively, due to different follow-up periods. The 5-year rate of carcinoma development was 34.0%. Risk factors for carcinoma development upon multivariate analysis were lesion size ≥15 mm and morphological depression. All cases with both factors developed gastric carcinoma, and 50.5% of those with either factor developed carcinoma within 5 years. Gastric adenoma was accompanied by metachronous gastric cancer in 1.5% of the patients annually. The only risk factor for metachronous gastric carcinoma was primary adenoma progressing to carcinoma during the follow-up period. Discussion/Conclusion: Given the high rate of carcinoma development in patients with risk factors, resection of gastric adenoma should be considered during the initial examination. Careful observation and follow-up should also be conducted to detect not only changes in the primary adenoma but also the occurrence of metachronous carcinoma, especially in cases of adenoma progressing to carcinoma.
Human CD8 T‐stem cell memory subsets phenotypic and functional characterization are defined by expression of CD122 or CXCR3

Long‐lived T‐memory stem cells (TSCM) are key to both naturally occurring and vaccine‐conferred protection against infection. These cells are characterized by the CD45RA+CCR7+CD95+ phenotype. Significant heterogeneity within the TSCM population is recognized, but distinguishing surface markers and functional characterization of potential subsets are lacking. Human CD8 TSCM subsets were identified in healthy subjects who had been previously exposed to CMV or Influenza (Flu) virus in flow cytometry by expression of CD122 or CXCR3, and then characterized in proliferation, multipotency, self‐renewal, and intracellular cytokine production (TNF‐α, IL‐2, IFN‐γ), together with transcriptomic profiles. The TSCMCD122hi‐expressing subset (versus CD122lo) demonstrated greater proliferation, greater multipotency, and enhanced polyfunctionality with higher frequencies of triple positive (TNF‐α, IL‐2, IFN‐γ) cytokine‐producing cells upon exposure to recall antigen. The TSCMCXCR3lo subpopulation also had increased proliferation and polyfunctional cytokine production. Transcriptomic analysis further showed that the TSCMCD122hi population had increased expression of activation and homing molecules, such as Ccr6, Cxcr6, Il12rb, and Il18rap, and downregulated cell proliferation inhibitors, S100A8 and S100A9. These data reveal that the TSCMCD122hi phenotype is associated with increased proliferation, enhanced multipotency and polyfunctionality with an activated memory‐cell like transcriptional profile, and hence, may be favored for induction by immunization and for adoptive immunotherapy.
Pharmacologic interventions for antidepressant-induced sexual dysfunction: a systematic review and network meta-analysis of trials using the Arizona sexual experience scale

Abstract Background Despite the prevalence of antidepressant-related sexual side effects, comparisons of treatments for these problematic side effects are lacking. Methods To address this, we performed a systematic review and Bayesian network meta-analysis to compare interventions for antidepressant-induced sexual dysfunction in adults. Using PubMed and clinicaltrials.gov, we identified published and unpublished prospective treatment trials from 1985 to September 2020 (primary outcome: the Arizona sexual experience scale [ASEX] score). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework. Results We identified 57 citations (27 randomized controlled trials, 66 treatment arms, 27 open-label trials, and 3 crossover trials) that evaluated 33 interventions (3108 patients). In the systematic review, 44% (25/57) of trials reported successful interventions; this was more common in open-label (70%, 19/27) compared to placebo-controlled studies (22%, 6/27). In the meta-analysis of placebo-controlled studies that used the ASEX (N = 8), pycnogenol was superior to placebo (standardized mean difference: −1.8, 95% credible interval [CrI]: [−3.7 to 0.0]) and there was evidence that, at a 6% threshold, sildenafil improved sexual dysfunction (standardized mean difference: −1.2, 95% CrI [−2.5 to 0.1]). In the meta-analysis including single-arm studies (15 studies), treatment response was more common with sildenafil, tianeptine, maca, tiagabine, and mirtazapine compared to placebo, but these differences failed to reach statistical significance. Conclusions While heterogeneity across randomized controlled trials complicates identifying the single best intervention, multiple trials suggest that sildenafil ameliorates antidepressant-induced sexual dysfunction. More randomized controlled trials are needed to examine the putative efficacy of other interventions.
Pathogenicity and virulence of West Nile virus revisited eight decades after its first isolation

ABSTRACT West Nile virus (WNV) is a flavivirus which transmission cycle is maintained between mosquitoes and birds, although it occasionally causes sporadic outbreaks in horses and humans that can result in serious diseases and even death. Since its first isolation in Africa in 1937, WNV had been considered a neglected pathogen until its recent spread throughout Europe and the colonization of America, regions where it continues to cause outbreaks with severe neurological consequences in humans and horses. Although our knowledge about the characteristics and consequences of the virus has increased enormously lately, many questions remain to be resolved. Here, we thoroughly update our knowledge of different aspects of the WNV life cycle: virology and molecular classification, host cell interactions, transmission dynamics, host range, epidemiology and surveillance, immune response, clinical presentations, pathogenesis, diagnosis, prophylaxis (antivirals and vaccines), and prevention, and we highlight those aspects that are still unknown and that undoubtedly require further investigation.

Impact of a Face-To-Face Versus Smartphone App Versus Combined Breastfeeding Intervention Targeting Fathers: Randomized Controlled Trial

Background Despite the recognized health and economic benefits of exclusive breastfeeding, few Australian infants are exclusively breastfed beyond 5 months of age. Social support for breastfeeding, in particular the support of an infant’s father, has been identified as a crucial element for successful breastfeeding. Objective The objective of this study was to determine the effectiveness of various father-focused breastfeeding interventions in terms of key infant feeding outcomes. Methods The study was a 4-arm, factorial, randomized controlled trial conducted in Perth, Australia. The trial arms included a control group and 3 interventions, consisting of a face-to-face father-focused antenatal breastfeeding class facilitated by a male peer facilitator; Milk Man, a breastfeeding smartphone app designed specifically for fathers; and a combination of both interventions. Expecting couples were recruited from hospital-based antenatal classes and block randomized to 1 of the 4 arms. Each partner completed surveys at recruitment and at 6 weeks and 26 weeks postpartum. Primary outcomes were duration of exclusive and any breastfeeding. Secondary outcomes included age of introduction of formula and complementary foods, maternal breastfeeding self-efficacy, and partner postpartum support. Results A total of 1426 couples were recruited from public (443/1426, 31.1%) and private (983/1426, 68.9%) hospitals. Of these, 76.6% (1092/1426) of fathers completed the baseline questionnaire, 58.6% (836/1426) completed the 6-week follow-up questionnaire, and 49.2% (702/1426) completed the 26-week follow-up questionnaire. The average age of fathers who completed the baseline questionnaire was 33.6 (SD 5.2) years; the majority were born in Australia (76.4%) and had attended university (61.8%). There were no significant differences between the control and any of the intervention groups in any of the infant feeding outcomes or level of breastfeeding self-efficacy and postpartum partner support reported by mothers. Conclusions This study did not demonstrate that any intervention was superior to another or that any intervention was inferior to the standard care delivered in routine antenatal classes. Further studies are needed to test the effectiveness of these interventions in more socioeconomically diverse populations that are likely to benefit most from additional partner supports.

Prospective BMI changes in preschool children are associated with parental characteristics and body weight perceptions: the ToyBox-study

Abstract Objective: To examine the effect of the intervention implemented in the ToyBox-study on changes observed in age- and sex-specific BMI percentile and investigate the role of perinatal factors, parental perceptions and characteristics on this change. Design: A multicomponent, kindergarten-based, family-involved intervention with a cluster-randomised design. A standardised protocol was used to measure children’s body weight and height. Information was also collected from parents/caregivers via the use of validated questionnaires. Linear mixed effect models with random intercept for country, socio-economic status and school were used. Setting: Selected preschools within the provinces of Oost-Flanders and West-Flanders (Belgium), Varna (Bulgaria), Bavaria (Germany), Attica (Greece), Mazowieckie (Poland) and Zaragoza (Spain). Participants: A sample of 6268 preschoolers aged 3·5–5·5 years (51·9 % boys). Results: There was no intervention effect on the change in children’s BMI percentile. However, parents’ underestimation of their children’s actual weight status, parental overweight and mothers’ pre-pregnancy overweight/obesity were found to be significantly and independently associated with increases in children’s BMI percentile in multivariate modelling. Conclusions: As part of a wide public health initiative or as part of a counseling intervention programme, it is important to assist parents/caregivers to correctly perceive their own and their children’s weight status. Recognition of excessive weight by parents/caregivers can increase their readiness to change and as such facilitate higher adherence to favourable behavioural changes within the family.
In-hospital outcome of primary PCI for patients with acute myocardial infarction and prior coronary artery bypass grafting

Background This study aims to analyze the in-hospital outcome of primary percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (AMI) and prior coronary artery bypass grafting (CABG). Methods This was a retrospective study. From January 2011 to December 2018, the data of 78 consecutive patients (study group) with prior CABG, who received primary coronary angiography in the setting of ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI), were screened. The study group was compared with another well-matched 78 patients without a history of CABG (control group). The information of the coronary angiograms and clinical data of both groups were analyzed. Multivariate conditional logistic regression models were constructed to test the association between PCI success rate and the prior CABG at age ≥65 and <65 years, respectively. Results The results revealed that the primary PCI success rate in the study group was significantly lower than in the control group (67.9% vs. 92.3%, P<0.001) and in-hospital mortality was significantly higher than in control group (11.5% vs. 2.5%, P=0.03). The multivariate logistic regression analysis indicated that the primary PCI success rate was significantly associated with the history of prior CABG both in young patients [age <65 years; odds ratio (OR) =5.26, 95% confidence interval (CI): 1.69–16.47] and elderly (age ≥65 years; OR =13.76, 95% CI: 2.72–69.75). Conclusions The patients who receive primary PCI with AMI and prior CABG have poor in-hospital outcomes, with low PCI success rates and high mortality.
Intracellular persistence of Staphylococcus aureus in endothelial cells is promoted by the absence of phenol-soluble modulins

ABSTRACT A large proportion of clinical S. aureus isolates that carry an inactive Agr system are associated with persistent infection that is difficult to treat. Once S. aureus is inside the bloodstream, it can cross the endothelial barrier and invade almost every organ in the human body. Endothelial cells can either be lysed by this pathogen or they serve as a niche for its intracellular long-term survival. Following phagocytosis, several vesicles such as phagosomes and autophagosomes, target intracellular S. aureus for elimination. S. aureus can escape from these vesicles into the host cytoplasm through the activation of phenol-soluble modulins (PSMs) αβ. Thereafter, it replicates and lyses the host cell to disseminate to adjacent tissues. Herein we demonstrate that staphylococcal strains which lack the expression of PSMs employ an alternative pathway to better persist within endothelial cells. The intracellular survival of S. aureus is associated with the co-localization of the autophagy marker LC3. In cell culture infection models, we found that the absence of psmαβ decreased the host cell lysis and increased staphylococcal long-term survival. This study explains the positive selection of agr-negative strains that lack the expression of psmαβ in chronic infection due to their advantage in surviving and evading the clearance system of the host.
A comparison of statistical methods for allocating disease costs in the presence of interactions

We consider the non‐trivial problem of estimating a health cost repartition among diseases from patients' hospital stays' global costs in the presence of multimorbidity, that is, when the patients may suffer from more than one disease. The problem is even harder in the presence of interactions among the disease costs, that is, when the costs of having, for example, two diseases simultaneously do not match the sum of the basic costs of having each disease alone, generating an extra cost which might be either positive or negative. In such a situation, there might be no “true solution” and the choice of the method to be used to solve the problem will depend on how one wishes to allocate the extra costs among the diseases. In this article, we study mathematically how different methods proceed in this regard, namely ordinary least squares (OLS), generalized linear models (GLM), and an iterative proportional repartition (IPR) algorithm, in a simple case with only two diseases. It turned out that only IPR allowed to retrieve the total costs and the unambiguous solution that one would have in a setting without interaction, that is, when no extra cost has to be allocated, while OLS and GLM may produce some negative health costs. Also, contrary to OLS, IPR is taking into account the basic costs of the diseases for the allocation of the extra cost. We conclude that IPR seems to be the most natural method to solve the problem, at least among those considered.
Effects of the COVID-19 Pandemic on Parkinson’s Disease: a Single-Centered Qualitative Study

ABSTRACT: Background: The public health measure restrictions across the world due to COVID-19 have inadvertently impacted the routines for people with Parkinson’s disease (PD) and their care partners not only in terms of compromised neurological clinical care but also drastically changing the way of life to minimize the risk of becoming infected. This study explores initial PD patients’ lived experiences to observe how quality of life and health care has been affected at the start of the COVID-19 pandemic and provide insight into the importance of patient engagement and virtual care. Methods: Twenty-two virtual, in-depth semi-structured interviews with persons diagnosed with PD who usually attend a Movement Disorders specialty clinic in Calgary, Alberta, were completed between April 28 and May 13, 2020, and the care partners that wished to participate. Interviews were recorded and transcribed, after which transcripts were analyzed and coded into relevant themes using NVivo 12. Results: Impacts from the public health measures and COVID-19 results into three main themes: (1) Impacts of COVID-19 on PD Clinical Care; (2) Activities of Daily Living; (3) Attitudes and Perceptions. Participants reported worsening in motor and nonmotor symptoms and had to accommodate to clinical care via virtual means which were associated with limitations and suggestions for improvement of remote care. Conclusion: This study provides a unique opportunity for researchers to better understand the lived experiences of PD patients in all aspects of their life suggesting that innovative means are needed for facilitating virtual health care medicine and increased social interaction.
Formation of radiation defects in silicate and borosilicate glasses caused by UV lamp and excimer laser irradiation

Solarization of colourless and coloured glasses of the type AR®, BK7® and DURAN® with high transmission in the UV-B region (280 to 320 nm) was investigated for their use as container glasses in the solar disinfection of drinking water. The samples were coloured by doping with NiO or CoO. The influence of the Fe 3+ /Fe 2+ content and of the reducing component Sn 2+ was investigated on both the initial transmission of the glasses and the solarization. The samples were irradiated with a 1 kW Xe lamp and a XeCl excimer laser. The solarization depends on the glass matrix and is enhanced by colouring ions. The influence of Fe 3+ /Fe 2+ and Sn 2+ on the defect generation is different for glasses coloured with NiO than for those coloured with CoO. For the samples investigated it was possible to simulate the loss of transmission in the UV-B region due to long-time irradiation with sunlight by a laser experiment.
The allometric propagation of COVID-19 is explained by human travel

We analyzed the number of cumulative positive cases of COVID-19 as a function of time in countries around the World. We tracked the increase in cases from the onset of the pandemic in each region for up to 150 days. We found that in 81 out of 146 regions the trajectory was described with a power-law function for up to 30 days. We also detected scale-free properties in the majority of sub-regions in Australia, Canada, China, and the United States (US). We developed an allometric model that was capable of fitting the initial phase of the pandemic and was the best predictor for the propagation of the illness for up to 100 days. We then determined that the power-law COVID-19 exponent correlated with measurements of human mobility. The COVID-19 exponent correlated with the magnitude of air passengers per country. This correlation persisted when we analyzed the number of air passengers per US states, an even per US metropolitan areas. Furthermore, the COVID-19 exponent correlated with the number of vehicle miles travelled in the US. Together, air and vehicular travel explained 70 % of the variability of the COVID-19 exponent. Taken together, our results suggest that the scale-free propagation of the virus is present at multiple geographical scales and is correlated with human mobility. We conclude that models of disease transmission should integrate scale-free dynamics as part of the modeling strategy and not only as an emergent phenomenological property.
Duration as Length Vs Amount in English and Spanish: A Corpus Study

ABSTRACT Previous psycholinguistic studies have suggested that English and Spanish express temporal duration through different metaphors. English tends to use the time-as-length metaphor (e.g. I have been waiting for a long time), while Spanish prefers the time-as-quantity metaphor (e.g. he esperado mucho tiempo; ‘I have waited much time’). However, these results conflated two different construals: the temporal duration construal, which can use length or quantity metaphors, (e.g. long time, that didn’t last much time) and the time-as-a-resource construal, which mostly employs quantity metaphors (e.g. you spent too much time). This study confirms through corpus linguistic data that English favors the time-as-length metaphor when expressing temporal duration, while it favors the time-as-quantity metaphor when expressing the time-as-a-resource construal. On the other hand, Spanish employs the time-as-quantity metaphor both in the duration and the resource construal. In addition, English shows a higher frequency of time-as-resource expressions, while Spanish shows a higher frequency of duration metaphors. This difference might be explained by the fact that English has been classified as a monochronic culture, conceptualizing time as a valuable object, while Spanish is a polychronic culture, categorizing time in a more abstract and flexible way.
The Effect of Some Nitrogenous Blend Components on NO/NOx and HCN Levels in Mainstream and Sidestream Smoke

Abstract Vapour phase NO concentrations in mainstream and sidestream smoke correlated well with blend nitrate levels over the range from 0.07 to 3.70 %. Native and added nitrate fit the same correlation. No measurable amounts of NO2 were detected in the vapour phase. When the mainstream and sidestream data were extrapolated to zero nitrate level, there remained a large residual amount of NO (approximately 100 µg /cig.) which could be attributed neither to nitrate nor to other nitrogenous blend components of the total volatile base type. Nitrogen-free cellulose cigarettes yielded of the order of 50 µg of NO per cigarette indicating that part of the residual NO probably arises from the oxidation of atmospheric nitrogen. The particulate phase contained small but measurable levels of nitrate which, with the exception of Mg(NO3) × 6 H2O added cigarettes, did not relate to blend nitrate levels. Mainstream vapour phase HCN level correlated weakly with blend nitrate levels but other nitrogenous materials whether native or added showed no clearly defined precursor-product relationship with smoke HCN yield. The partitioning of HCN between the vapour and particulate phases was not affected by any of the test variables.
