Synergistic effects of piperlongumine and gemcitabine against KRAS mutant lung cancer
Authors: Ye Wu , Huang Qingdong , Tang Tingyu , Qin Guangyue 
Published: June 2020

Objective: To determine the combined efficacy of piperlongumine and gemcitabine for treatment of KRAS mutant lung cancer. Methods: The cell growth inhibition of piperlongumine, gemcitabine, and piperlongumine plus gemcitabine was measured by Cell Counting Kit‑8 assay and the combination index was calculated. In addition, the combined effects of piperlongumine and gemcitabine on cell apoptosis, reactive oxygen species (ROS) contents, and microtubule-associated protein 1 light chain 3B (LC3B) expression were examined. Results: Piperlongumine increased ROS contents and LC3B-II expression. Following the combined treatment with piperlongumine and 10 mM N-acetyl-L-cysteine (NAC), intracellular ROS and cell viability returned to normal levels, and the expression of LC3B-II decreased to the predose level. Gemcitabine also induced cell apoptosis, increased ROS contents, and LC3B-II expression. The combination of piperlongumine with gemcitabine exhibited a synergetic anticancer activity with the combination index <1. The combined application of gemcitabine and piperlongumine yielded synergistic effects on cell apoptosis, but failed to synergistically increase ROS levels and LC3B-II expression. Conclusion: Combination therapy with piperlongumine and gemcitabine is a promising treatment option for KRAS mutant lung cancer.

Published: June 2020

Objective: Several studies indicate that macrophage migration inhibitory factor 1 plays a role for tumor progression in colon cancer. We investigated whether determination of migration inhibitory factor 1 mRNA expression levels in lymph nodes of colon cancer patients could be used as a prognostic marker. Methods: Expression levels of migration inhibitory factor 1 and carcinoembryonic antigen mRNAs were assessed in primary tumors and regional lymph nodes of 123 colon cancer patients (stages I–IV), and in colon cancer- and immune cell lines using quantitative reverse transcriptase–polymerase chain reaction. Expression of migration inhibitory factor 1 protein was investigated by two-color immunohistochemistry and immunomorphometry. Results: Migration inhibitory factor 1 mRNA was expressed at 60 times higher levels in primary colon cancer tumors compared to normal colonic tissue (medians 8.2 and 0.2 mRNA copies/18S rRNA unit; p < .0001). A highly significant difference in mRNA expression levels was found between hematoxylin-eosin positive lymph nodes and hematoxylin-eosin negative lymph nodes (p < .0001). Migration inhibitory factor 1 and carcinoembryonic antigen proteins were simultaneously expressed in many colon cancer-tumor cells. Kaplan–Meier survival model and hazard ratio analysis, using a cutoff level at 2.19 mRNA copies/18S rRNA unit, revealed that patients with lymph nodes expressing high levels of migration inhibitory factor 1 mRNA had a 3.5-fold (p = .04) higher risk for recurrence, associated with a small, but significant, difference in mean survival time (7 months, p = .03) at 12 years of follow-up. Conclusion: Although migration inhibitory factor 1 mRNA expression levels were related to severity of disease and lymph node analysis revealed that colon cancer patients with high levels had a shorter survival time after surgery than those with low levels, the difference was small and probably not useful in clinical practice.

Published: June 2020

Purpose: To report a case of quiescent choroidal neovascularization (CNV) associated with choroidal nevus using optical coherence tomography angiography (OCTA) during 5 years follow-up. Methods: Observational case report. Results: A 53-year old woman was referred our department with diagnosis of choroidal nevus. At 1 year follow-up, fundus autofluorescence revealed hyper/hypoautofluorescent area, infrared image showed hyperreflective area and enhanced depth imaging OCT presented a shallow pigment epithelium detachment without exudation or hemorrhage. Fluorescein angiography and indocyanine green angiography suspected the presence of CNV. Finally, OCTA confirmed a quiescent CNV with an increased flow area of the vascular lesion without any changes in best-corrected visual acuity. At 20 months and 5 years follow-up, the CNV remained quiescent showing no clinical activity on structural SD-OCT and no changes in CNV morphology on OCTA. Conclusion: This case shows the features of quiescent CNV secondary to choroidal nevus after long-term follow-up. OCTA represents a valid imaging technique that allows to identify the CNV and to monitor its progression over time.
Can Users Search Trends Predict People Scares or Disease Breakout? An Examination of Infectious Skin Diseases in the United States
Authors: Obeidat Rand , Alsmadi Izzat , Bani Bakr Qanita , Obeidat Laith 
Published: June 2020

Background: In health and medicine, people heavily use the Internet to search for information about symptoms, diseases, and treatments. As such, the Internet information can simulate expert medical doctors, pharmacists, and other health care providers. Aim: This article aims to evaluate a dataset of search terms to determine whether search queries and terms can be used to reliably predict skin disease breakouts. Furthermore, the authors propose and evaluate a model to decide when to declare a particular month as Epidemic at the US national level. Methods: A Model was designed to distinguish a breakout in skin diseases based on the number of monthly discovered cases. To apply this model, the authors correlated Google Trends of popular search terms with monthly reported Rubella and Measles cases from Centers for Disease Control and Prevention (CDC). Regressions and decision trees were used to determine the impact of different terms to trigger the occurrence of epidemic classes. Results: Results showed that the volume of search keywords for Rubella and Measles rises when the volume of those reported diseases rises. Results also implied that the overall process was successful and should be repeated with other diseases. Such process can trigger different actions or activities to be taken when a certain month is declared as “Epidemic.” Furthermore, this research has shown great interest for vaccination against Measles and Rubella. Conclusions: The findings suggest that the search queries and keyword trends can be truly reliable to be used for the prediction of disease outbreaks and some other related knowledge extraction applications. Also search-term surveillance can provide an additional tool for infectious disease surveillance. Future research needs to re-apply the model used in this article, and researchers need to question whether characterizing the epidemiology of Coronavirus Disease 2019 (COVID-19) pandemic waves in United States can be done through search queries and keyword trends.
Self-efficacy, recovery and psychological wellbeing one to five years after heart transplantation: a Swedish cross-sectional study
Authors: Almgren Matilda , Lundqvist Pia , Lennerling Annette , Forsberg Anna 
Published: June 2020

Abstract

Background
Self-efficacy refers to a person´s confidence in carrying out treatment-related activities and constitutes the foundation of self-management as well as long-term follow-up after heart transplantation. Exploring the heart recipients´ experiences by means of self-report instruments provides healthcare professionals with valuable information on how to supply self-management support after heart transplantation.

Aims
The aim was to explore self-efficacy in relation to the self-reported level of recovery and psychological wellbeing, among adult heart recipients, one to 5 years after transplantation.

Methods
This cross-sectional study includes 79 heart recipients, due for follow-up one to 5 years after transplantation. Three different self-assessment instruments were employed: the self-efficacy for managing chronic disease 6-item scale; the postoperative recovery profile; and the psychological general wellbeing instrument.

Results
The reported level of self-efficacy was high (median 8.3, maximum score 10). Significantly higher self-efficacy was seen among those who had returned to work (P = 0.003) and those without pre-transplant mechanical circulatory support (P = 0.033). In total, 65.5% (n = 52) reported being reasonably recovered, while 18.8% (n = 12) were not recovered. The median total psychological general wellbeing score was 108 (P25 = 24, P75 = 117), suggesting overall good psychological wellbeing in the whole group of heart recipients.

Conclusion
The heart transplant recipients in our study had an overall high level of self-efficacy. Low self-efficacy was found among those with a low self-reported level of recovery, pre-transplant treatment with mechanical circulatory support or who had not returned to work. This is important information for transplant professionals when helping heart recipients to balance their expectations about recovery.
Gender-Based Violence, Perspectives in Latin America and the Caribbean

Published: June 2020

Introduction: To address the phenomenon of gender-based violence in Latin America and the Caribbean is an issue of epic proportion that reflects the unequal power dynamics created within the binary gender system and is often perpetrated by those with more physical, cultural, or social power and inflicted upon those without. Method: Each database was comprehensively searched for MeSH keyword combinations of gender violence (violence against women) or (gender-based violence) with the region of interest (Latin America and the Caribbean) in addition to a third word or phrase regarding health care (health care training, training, health care curricula, curricula, health care professionals). Results: After completing this scope review, we have found a widespread call for more comprehensive preparation for health care professionals involved in identifying and addressing gender-based violence. Conclusions: Though some research has been conducted documenting the ways in which gender-based violence is managed or not managed by health care providers, Latin America and the Caribbean in particular represent a gap in research on health care tools and their effectiveness in these situations. There is a distinct need for the creation of context-specific protocols for vulnerable and underrepresented groups.
Impact of obesity on male urethral sling outcomes
Authors: Monn M. Francesca , Jarvis Hannah V. , Gardner Thomas A. , Mellon Matthew J. 
Published: June 2020

Background: The impact of obesity on AdVance male urethral sling outcomes has been poorly evaluated. Anecdotally, male urethral sling placement can be more challenging due to body habitus in obese patients. The objective of this study was to evaluate the impact of obesity on surgical complexity using operative time as a surrogate and secondarily to evaluate the impact on postoperative pad use. Methods: A retrospective cohort analysis was performed using all men who underwent AdVance male urethral sling placement at a single institution between 2013 and 2019. Descriptive statistics comparing obese and non-obese patients were performed. Results: A total of 62 patients were identified with median (IQR) follow up of 14 (4–33) months. Of these, 40 were non-obese and 22 (35.5%) were obese. When excluding patients who underwent concurrent surgery, the mean operative times for the non-obese versus obese cohorts were 61.8 min versus 73.7 min ( p = 0.020). No Clavien 3–5 grade complications were noted. At follow up, 47.5% of the non-obese cohort and 63.6% of the obese cohort reported using one or more pads daily ( p = 0.290). Four of the five patients with a history of radiation were among the patients wearing pads following male urethral sling placement. Conclusion: Obese men undergoing AdVance male urethral sling placement required increased operative time, potentially related to operative complexity, and a higher proportion of obese compared with non-obese patients required postoperative pads for continued urinary incontinence. Further research is required to better delineate the full impact of obesity on male urethral sling outcomes.
Mindful body scans and sonographic biofeedback as preparatory activities to address patient psychological states in hand therapy: A pilot study
Authors: Roll Shawn C , Hardison Mark E , Vigen Cheryl , Black David S 
Published: June 2020

Introduction Translational evidence for mind–body interventions in hand therapy is limited. This pilot study aimed to determine potential benefits of including a mindful body scan or sonographic biofeedback at the outset of a hand therapy session on key psychological states. Methods A randomized, repeated-measures, cross-over design was used to evaluate a mindful body scan and sonographic biofeedback at the outset of a hand therapy session. Measures of pain, anxiety, and stress (i.e. salivary cortisol) were obtained from 21 hand therapy patients at the start, after 20 min, and at the end of each of three 60-min treatments. Trends were examined, and mixed-effects regression compared effects across time within and across the sessions for each of the outcome measures. Results For all intervention types, anxiety and stress decreased across the treatment session ( p < 0.001); no statistically significant changes were noted in pain. Using either mind–body intervention before standard care resulted in a meaningful decrease and statistical trend toward improvement in stress. The use of a mindful body scan produced an immediate, statistically significant reduction in anxiety (β = − 0.14, p = 0.03), a lowered level that was maintained throughout the therapy session. Discussion These data provide preliminary support for integrating mind–body interventions as preparatory activities in hand therapy. Mindful body scans may prepare patients for therapeutic interventions by more quickly reducing anxiety, and the use of either intervention may reduce patient stress more than would occur during a standard care session. These effects should be evaluated in an adequately powered clinical trial.

Published: June 2020

Background: Our institution is the largest pediatric kidney transplantation (KT) center in Canada and the referral center for pediatric KT in Ontario. Pediatric KT recipients are referred to our center for KT and transferred back to their local tertiary care institutions for post-transplant care. This investigation assesses whether the current system of transferring patients back to their local tertiary care institutions following KT allows decreased burden and distribution of resources from a single centralized surgical center. Methods: A retrospective review of KT performed at our institution between 2000 and 2015 was performed. Patients were divided into those who began their chronic kidney disease (CKD) care at our institution and those who began their care elsewhere. Readmission to our institution within 1 year of KT for surgical and nonsurgical complications was compared. The geographical proximity of patients to our institution and institution of initial CKD care was assessed quantitatively and mapped visually. Results: Of 324 patients who underwent KT, 244 (75.3%) began their CKD care at our institution. Those who began their CKD care at other institutions had shorter initial admissions to our institution (17 [14-24] vs 14 [12-17], P < .0001) and were less likely to be readmitted to our institution for nonsurgical concerns at <6 months after transplant ( P < .0001) and 6 to 12 months after transplant ( P < .0001). There were similar readmissions for complications requiring surgical management. The relationship between the center of CKD initiation and readmission remained significant on multivariate analysis. There was a significant difference in distance (km) to our institution between the 2 groups (46 [interquartile range = 24-109] vs 203 [117-406], P < .0001). Conclusion: Patients who are geographically distanced from our institution began their CKD care at their closest institution and were managed effectively at those institutions following initial discharge/transfer of care, suggesting that there is an effective distribution of health care resources with regard to CKD and KT care.
Profit Efficiency as a Measure of Performance and Frontier Models: A Resource-Based View

Published: June 2020

Although the resource-based view (RBV) of the firm is one of the most accepted theories of strategic management, it has been criticized for its limited empirical support. The RBV basically predicts the relationship between the firm’s resources and its performance. This study argues that it is more appropriate to measure firm performance using profit efficiency than traditional financial or accounting measures and that frontier models have great potential in empirical research on the RBV. To test this idea empirically, we used a stochastic frontier model with random coefficients to evaluate the impact of corporate reputation on profit efficiency. Finally, implications of the aforementioned focal points are discussed. JEL classification: C11, L25, M10, M20

Published: June 2020

Introduction: Oral health affects quality of life. Many studies have investigated the factors associated with oral health–related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services. Objectives: To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y. Methods: A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3. Results: There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India. Conclusions: Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts. Knowledge Transfer Statement: This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

Abstract
Gray zone lymphoma (GZL), a B-cell lymphoma with features intermediate between large B-cell lymphoma (LBCL) and classic Hodgkin lymphoma (cHL), is a rare and poorly defined entity. Alongside GZL, a subset of Epstein-Barr virus (EBV)–positive diffuse large B-cell lymphoma (DLBCL) has been described with polymorphic/GZL-like morphology (polymorphic-EBV-L). To fill the important gap in our understanding of the pathogenic process underlying these entities, we performed a gene expression study of a large international cohort of GZL and polymorphic-EBV-L, combined with cHL and primary mediastinal large B-cell lymphoma (PMBCL) cases. In an unsupervised principal component analysis, GZL cases presented with intermediate scores in a spectrum between cHL and PMBCL, whereas polymorphic-EBV-L clustered distinctly. The main biological pathways underlying the GZL spectrum were related to cell cycle, reflecting tumor cell content, and extracellular matrix signatures related to the cellular tumor microenvironment. Differential expression analysis and phenotypic characterization of the tumor microenvironment highlighted the predominance of regulatory macrophages in GZL compared with cHL and PMBCL. Two distinct subtypes of GZL were distinguishable that were phenotypically reminiscent of PMBCL and DLBCL, and we observed an association of PMBCL-type GZL with clinical presentation in the “thymic” anatomic niche. In summary, gene expression profiling (GEP) enabled us to add precision to the GZL spectrum, describe the biological distinction compared with polymorphic-EBV-L, and distinguish cases with and without thymic involvement as 2 subgroups of GZL, namely PMBCL-like and DLBCL-like GZL.
