Value and engagement: what can clinical trials learn from techniques used in not-for-profit marketing?
Authors: Mitchell E. J. , Sprange K. , Treweek S. , Nixon E. 
Published: June 2022

AbstractMarketing is a core business function in commercial companies but is also frequently used by not-for-profit organisations. Marketing focuses on understanding what people value to make choices about engaging with a product or service: a concept also key to understanding why people may choose to engage with a clinical trial. Understanding the needs and values of stakeholders, whether they are participants, staff at recruiting sites or policy-makers, is critical for a clinical trial to be a success. As many trials fail to recruit and retain participants, perhaps it is time for us to consider approaches from other disciplines. Though clinical trial teams may consider evidence- and non-evidence-based recruitment and retention strategies, this is rarely done in a systematic, streamlined way and is often in response to challenges once the trial has started. In this short commentary, we argue the need for a formal marketing approach to be applied to clinical trials, from the outset, as a potential prevention to recruitment and retention problems.
A nonrandomized controlled trial of individualized exercise prescription combined with remote exercise management in patients who are overweight or obese
Authors: Guan Rui , Li Haijing , Jiao Yang , Yu Hong 
Published: June 2022

Abstract
Background
Between 2012 and 2020, the obesity rate increased among Chinese people aged 18 years and above, along with blood pressure, fasting blood glucose, serum total cholesterol, and triglycerides.

Purpose
Our objective was to compare the effects of a combined intervention, including individualized exercise prescription plus remote management versus individualized exercise prescription only, on cardiovascular risk factors in patients who are overweight or obese, with the aim of establishing a more effective remote model of health management than self-management.

Methods
This nonrandomized controlled trial (ChiCTR2100046307) studied patients who are overweight or obese at model labor health management centers from January 2019 to December 2019, including 55 people in the experimental group and 34 in the control group. The relevant indexes of all the research objects from both experimental group and control group were examined. Participants in the experimental group were given individualized exercise prescription combined with remote exercise management over a period of 3 months. The control group was prescribed exercise only at time of enrollment and taught about exercise once, followed by voluntary exercise and self-management for 3 months.

Result
After adjusting for baseline differences, the changes in weight (−2.72 ± 4.03 kg versus 0.32 ± 2.50 kg, P < 0.0001), body mass index (−0.99 ± 1.44 kg/m2 versus 0.11 ± 0.92 kg/m2, P < 0.0001), waist circumference (−2.98 ± 6.29 cm versus 0.60 ± 5.33 cm, P < 0.0001), visceral fat area (−9.75 ± 19.68 cm2 versus −1.31 ± 12.37 cm2, P = 0.028), body fat (− 2.65 ± 3.52 kg versus 0.54 ± 2.67 kg, P < 0.0001), body fat rate (−2.50 ± 3.32% versus 0.21 ± 3.30%, P < 0.0001), uric acid (−9.75 ± 19.68 µmol/L versus −1.31 ± 12.37 µmol/L, P = 0.028), serum total cholesterol (−0.11 ± 0.40 mmol/L versus −0.11 ± 0.59 mmol/L, P = 0.004), fasting insulin (− 2.36 ± 5.20 μU/mL versus 1.22 ± 7.34 μU/mL, P = 0.009), and homeostatic model assessment of insulin resistance (−0.62 ± 1.25 versus 0.14 ± 1.83, P = 0.022) were significantly better in the experimental group than in the control group after intervention.

Conclusion
Individualized exercise prescription combined with remote management in patients who are obese or overweight facilitated weight and fat loss, lowered blood pressure and serum total cholesterol, improved glucose metabolism and insulin resistance, and reduced cardiovascular risk factors. The intervention was superior to conventional education in terms of weight loss, fat reduction, total cholesterol reduction, fasting insulin reduction, and amelioration of insulin resistance.
Type 1 neurodegeneration with brain iron accumulation: a case report
Authors: Labrada-Aguilera Pedro Enrique , Guach-Hevia David Armando , Almira-Gómez Carlos Rafael , González-Lago Daniel Alejandro 
Published: June 2022

Abstract
Background
Type 1 neurodegeneration with brain iron accumulation is a rare neurological disorder with estimated prevalence of one to two per million persons worldwide, characterized by progressive degeneration of basal ganglia, globus pallidus, and reticular part of substantia nigra, produced by brain iron accumulation due to a defect in the gene producing pantothenate kinase 2. Clinical presentations include dystonia, dysarthria, dysphagia, dementia, severe mental retardation, and severe movement disability at later stages. The characteristic pattern on brain magnetic resonance imaging shows the “eye of the tiger” sign. Treatment in late stages is mainly symptomatic. We report the case of a Cuban boy with high-severity brain iron accumulation, with positive clinical and imaging findings diagnosed in a late stage of the illness. This degree of severity has never been reported in Cuba and is rarely reported worldwide.

Case presentation
We present the case of a 19-year-old male white Cuban boy who presented to our department with features of spasticity, dystonia, gait difficulty, dysarthria, dysphagia, aggressiveness, and sleep disorders. He was diagnosed with pantothenate kinase-associated neurodegeneration on the basis of clinical findings and typical “eye of the tiger” pattern on brain magnetic resonance imaging. Detailed evaluation was carried out, and symptomatic treatment and physiotherapy were started with trihexyphenidyl, cabergoline, baclofen, and intramuscular botulinum neurotoxin as well as daily home sessions of passive stretching, weight bearing, and muscle massaging. At 3 months reevaluation, the patient showed a great improvement of motor function, with a decrease of dystonic symptoms, although language, cognition, and functional independence showed no improvement. The prognosis of the patient remains reserved.

Conclusion
The diagnosis can be made based on the presence of clinical and imaging features. The presence of “eye-of-the-tiger” sign on magnetic resonance imaging must be considered a nearly pathognomonic sign of neurodegeneration with brain iron accumulation presence. Treatment after high-severity presentation remains directed toward symptomatic findings. Both dopamine agonists and anticholinergic agents are useful to treat motor symptoms, but there is not yet an effective treatment to stop the underlying degeneration. New therapeutic approaches are needed to counteract late stages of the disease and improve prognosis.
Beclin1 haploinsufficiency compromises mesenchymal stem cell-offered cardioprotection against myocardial infarction

Published: June 2022

AbstractMesenchymal stem cells (MSCs)-based therapy has displayed some promises in ischemia heart diseases although its efficacy may be affected by changes in surrounding environments. This study evaluated the role of autophagy insufficiency using Beclin1 haploinsufficiency (BECN+/−) on intra-myocardial MSC transplantation-evoked effect against myocardial infarction. Donor MSCs from C57BL/6 mice were labelled with cell-tracker CM Dil and were delivered into LV free wall adjacent to infarct region in wild-type (WT) and BECN+/− recipient mice following ligation of left main coronary artery (MI-MSCs). Ten days following MI, myocardial function was assessed using echocardiography. Cardiomyocyte contractility and intracellular Ca2+ were monitored using cardiomyocytes from the area-at-risk adjacent to infarct. CM-Dil labeled cells were tracked in MSCs recipient mice using fluorescence microscopy. Lectin, Masson trichrome staining and Western blot analysis were employed to determine cardiomyocyte area, scar fibrosis, apoptosis and inflammation. MI insult triggered scar fibrosis, LV chamber dilation, decreased fractional shortening, ejection fraction, cardiomyocyte shortening, maximal velocity of shortening and relengthening as well as prolonged relengthening, which were abrogated or attenuated by MSCs therapy in WT but not BECN+/− mice. MI decreased intracellular Ca2+ rise and decay in response to electrical stimuli without affecting resting intracellular Ca2+, which were reconciled by MSCs in WT but not BECN+/− mice. MSCs further attenuated MI-induced mitochondrial ultrastructural injury, apoptosis, inflammation and autophagy defects in peri-infarct area in WT but not BECN+/− mice. Collectively, our results suggested that autophagy insufficiency dampened in MSCs-elicited cardioprotection associated with dampened apoptosis and inflammation.

Abstract
Background
When people who recently travelled abroad are admitted to a hospital back home, there is a risk of introducing highly resistant microorganisms (HRMO) into the hospital. To minimize this risk, a feasible infection prevention strategy should be developed. In this study, we investigated patients’ travel history and behavior during travel and analyzed whether this was correlated to HRMO carriage at admission.

Methods
From May 2018 until August 2019, adult patients admitted to a large tertiary care center in the Netherlands were asked upon hospital admission to participate in the study. Included patients received a questionnaire about risk perception, travel history in the last year, and behavior during travel, and were screened for HRMO carriage at admission using a perianal swab.

Results
Six hundred and eight questionnaires were handed out, of which 247 were returned (40.6%). One hundred and thirty (52.6%) patients did not travel abroad in the last year, of whom eight (6.2%) were HRMO carrier at admission. One hundred seventeen (47.4%) patients travelled in the preceding year, of whom seven patients (6.0%) were HRMO carrier at admission. Thirty patients (12%) travelled outside of Europe; in this group HRMO prevalence was 13.3% (4 out of 30). The majority of patients (71.3%) were aware that international travel could lead to carriage of HRMO, and an even larger majority (89.5%) would support a screening strategy upon hospital admission in case of a travel history, to minimize the risk of introducing HRMO.

Conclusions
We identified that half of admitted patients to a large tertiary care hospital travelled abroad in the last year, with only a small percentage outside Europe. We discuss several screening strategies and propose a strategy of screening and preemptive isolation of patients who travelled to Asia or Africa in the 2 months before their hospital admission; a strategy that patients would support.

Authors: Azami Mobin , Moradi Yousef , Moradkhani Asra , Aghaei Abbas 
Published: June 2022

Abstract
Background
Covid-19 has been one of the major concerns around the world in the last 2 years. One of the challenges of this disease has been to determine its prevalence. Conflicting results of the serology test in Covid explored the need for an updated meta-analysis on this issue. Thus, this systematic review aimed to estimate the prevalence of global SARS-CoV-2 serology in different populations and geographical areas.

Methods
To identify studies evaluating the seroprevalence of SARS-CoV-2, a comprehensive literature search was performed from international databases, including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL.

Results
In this meta-analysis, the results showed that SARS-CoV-2 seroprevalence is between 3 and 15% worldwide. In Eastern Mediterranean, the pooled estimate of seroprevalence SARS-CoV-2 was 15% (CI 95% 5–29%), and in Africa, the pooled estimate was 6% (CI 95% 1–13%). In America, the pooled estimate was 8% (CI 95% 6–11%), and in Europe, the pooled estimate was 5% (CI 95% 4–6%). Also the last region, Western Pacific, the pooled estimate was 3% (CI 95% 2–4%). Besides, we analyzed three of these areas separately. This analysis estimated the prevalence in subgroups such as study population, diagnostic methods, sampling methods, time, perspective, and type of the study.

Conclusion
The present meta-analysis showed that the seroprevalence of SARS-CoV-2 has been between 3 and 15% worldwide. Even considering the low estimate of this rate and the increasing vaccination in the world, many people are still susceptible to SARS-CoV-2.

Abstract
Background
Chronic graft-versus-host disease (cGVHD) remains a major complication during the late phase of allogeneic hematopoietic stem cell transplantation (allo-HSCT). IL-39, a newly described pro-inflammatory cytokine belonging to the IL-12 family, plays a role in lupus development. Recently, IL-39 has been identified as a pathogenic factor in acute GVHD (aGVHD). However, the role of IL-39 in the pathogenesis of cGVHD remains unclear.

Methods
We constructed a recombinant IL-39 plasmid and established scleroderma and lupus-like cGVHD models. Quantitative PCR and enzyme-linked immunosorbent assay (ELISA) were used to detect IL-39 expression in mice and patients post transplantation, respectively. Hydrodynamic gene transfer (HGT) was performed to achieve IL-39 overexpression in vivo. Multiparameter flow cytometry, western blotting, and assays in vitro were performed to investigate the effect of IL-39 on cGVHD.

Results
The relative expression of IL-23p19 and EBi3 was significantly increased in the intestine of cGVHD mice on day 40 post allo-HSCT, and IL-39 levels were significantly elevated in the serum of patients following allo-HSCT. Overexpression of IL-39 significantly aggravated the severity of cGVHD. Increased IL-39 levels promoted T-cell activation and germinal center responses, and may exacerbate thymic damage. Consistently, blocking IL-39 markedly ameliorated immune dysregulation in the cGVHD mice. Furthermore, we found that IL-39 was produced by B cells, CD11b+ cells, and CD8+T cells after activation. Stimulation of IL-39 led to upregulation of the IL-39 receptor on CD4+T cells and further caused activation of the STAT1/STAT3 pathway, through which IL-39 may exert its pro-inflammatory effects.

Conclusion
Our study reveals a critical role for IL-39 in cGVHD pathogenesis and indicates that IL-39 may serve as a potential therapeutic target for cGVHD prevention.
Developing insights from the collective voice of target users in Twitter
Authors: Lee Kang-Pyo , Song Suyong 
Published: June 2022

AbstractThis study develops a pragmatic scheme that facilitates insight development from the collective voice of target users in Twitter, which has not been considered in the existing literature. While relying on a wide range of existing approaches to Twitter user profiling, this study provides a novel and generic procedure that enables researchers to identify the right users in Twitter and discover topical and social insights from their tweets. To identify a target audience of Twitter users that meets certain criteria, we first explore user profiling, potentially followed by text-based, customized user profiling leveraging hashtags as features for machine learning. We then present how to mine popular topics and influential actors from Twitter data. Two case studies on 16 thousand young women interested in fashion and 68 thousand people sharing the same interest in the Me Too movement indicate that our approach facilitates discovery of social trends among people in a particular domain.
A survey on the use of mice, pigs, dogs and monkeys as animal models in biomedical research in Spain

Published: June 2022

AbstractBackgroundThe use of animals in biomedical science remains controversial. An individual’s level of concern is generally influenced by their culture, previous or current experience with animals, and the specific animal species in question. In this study we aimed to explore what people in Spain who had never or who no longer worked with laboratory animals thought of the use of mice, pigs, dogs and monkeys for biomedical research purposes. We also aimed to determine whether or not people currently involved in biomedical research with the aforementioned species felt their work was justified.ResultsThe study comprised a total of 807 participants (never worked = 285, used to work = 56, currently working = 466), almost two thirds of whom were women. Our results revealed that the phylogenetic scale is an important factor in people’s opinions of the use of certain species in research. The percentage of people who were against the use of dogs or monkeys was higher than that of those who were against the use of mice or pigs. The main reasons given for having stopped working with laboratory animals were change of professional career and change in research project. Participants who were currently working with animals believed that their work was justified, but said they did not talk about it with people outside their immediate social circle.ConclusionsOur findings suggest that there is a difference in moral status between monkeys and mice, as well as between companion animals (dogs) and farm animals (pigs). Our results support the idea that working with laboratory animals is a sensitive issue in Spain.

Published: June 2022

Abstract
Background
Leaf spot disease of Telfairia occidentalis, caused by Phoma sorghina, represents one of the major biotic constraints to T. occidentalis production under small scale farming systems in West Africa including Cameroon. Currently this critically important seed and leaf vegetable is cultivated under varying altitudinal levels at different planting dates. In this framework, a field study was conducted in 2019 and 2020 cropping seasons between March and July in the localities of Dschang and Santchou to determine the influence of altitude and planting date on the prevalence and severity the disease.

Material and methods
A 2 by 4 factorial randomized complete block design (RCBD) with three replications and four planting dates were used. Data for disease prevalence and severity documented fortnightly, were submitted to general linear model for analysis using SPSS version 23, and the means were separated by least significant difference (LSD) at a 95% confidence interval.

Results
Statistical analysis revealed that, the low altitude recorded a significantly (p < 0.05) lower prevalence than high altitude while disease severities between both altitudes were not significantly different. Moreover, the initial three planting dates at low altitude and planting date three in Dschang recorded significantly lower prevalence than other planting dates investigated in the study.

Conclusion
We established that, the initial three planting dates at low altitude and planting date three at high altitude could be helpful in reducing leaf spot prevalence and severity of T. occidentalis.
Urinary incontinence in women - the overview of pharmacological and surgical methods
Authors: Mikut Karolina , Wijata Aleksandra , Gorajek Anna , Kędziora-Kornatowska Kornelia 
Published: June 2022

Introduction and purpose of the work:
Urinary incontinence (UI) is a common problem among women and the incidence increases with age. It is estimated that about 50% of women will be affected by this problem. There are 5 types of urinary incontinence: exercise, pressure, mixed, overflow and functional. Stress UI is the most common cause among young women, while stress UI is the second most common cause among older women. The widespread use of this phenomenon makes it a significant economic burden.
State of knowledge (brief description):
Due to the different types of UI and its many causes, treating this disorder becomes a significant challenge. It is important to use combination therapy, starting with pelvic floor muscle strengthening exercise, lifestyle modification, weight loss, and smoking cessation, followed by drug therapy and surgery as necessary.
Summary:
Currently, many drugs are used in the treatment of urinary incontinence, with different mechanisms of action, which allow the treatment of various types of UI, but pharmacotherapy often does not bring the expected benefits. Surgical treatment appears to be a promising form of treatment, but more research is needed on the long-term effects.
