Abstract
Background
Increasing evidence suggests that platelets play a central role in cancer progression, with altered storage and selective release from platelets of specific tumor-promoting proteins as a major mechanism. Fluorescence-based super-resolution microscopy (SRM) can resolve nanoscale spatial distribution patterns of such proteins, and how they are altered in platelets upon different activations. Analysing such alterations by SRM thus represents a promising, minimally invasive strategy for platelet-based diagnosis and monitoring of cancer progression. However, broader applicability beyond specialized research labs will require objective, more automated imaging procedures. Moreover, for statistically significant analyses many SRM platelet images are needed, of several different platelet proteins. Such proteins, showing alterations in their distributions upon cancer progression additionally need to be identified.

Results
A fast, streamlined and objective procedure for SRM platelet image acquisition, analysis and classification was developed to overcome these limitations. By stimulated emission depletion SRM we imaged nanoscale patterns of six different platelet proteins; four different SNAREs (soluble N-ethylmaleimide factor attachment protein receptors) mediating protein secretion by membrane fusion of storage granules, and two angiogenesis regulating proteins, representing cargo proteins within these granules coupled to tumor progression. By a streamlined procedure, we recorded about 100 SRM images of platelets, for each of these six proteins, and for five different categories of platelets; incubated with cancer cells (MCF-7, MDA-MB-231, EFO-21), non-cancer cells (MCF-10A), or no cells at all. From these images, structural similarity and protein cluster parameters were determined, and probability functions of these parameters were generated for the different platelet categories. By comparing these probability functions between the categories, we could identify nanoscale alterations in the protein distributions, allowing us to classify the platelets into their correct categories, if they were co-incubated with cancer cells, non-cancer cells, or no cells at all.

Conclusions
The fast, streamlined and objective acquisition and analysis procedure established in this work confirms the role of SNAREs and angiogenesis-regulating proteins in platelet-mediated cancer progression, provides additional fundamental knowledge on the interplay between tumor cells and platelets, and represent an important step towards using tumor-platelet interactions and redistribution of nanoscale protein patterns in platelets as a basis for cancer diagnostics.

Authors: Qin Shang-Dong , Zhang Jie , Qi Ya-Peng , Zhong Jian-Hong , Xiang Bang-De 
Published: June 2022

Abstract
Background and objectives
To evaluate the individual and combined associations of cytokeratin 19 (CK19) and microvascular invasion (MVI) with prognosis of patients with hepatocellular carcinoma (HCC).

Methods
Clinicopathological data on 352 patients with HCC who underwent radical resection at our hospital between January 2013 and December 2015 were retrospectively analyzed. Patients were divided into four groups: CK19(−)/MVI(−), CK19(−)/MVI(+), CK19(+)/MVI(−), and CK19(+)/MVI(+).

Results
Of the 352 HCC patients, 154 (43.8%) were CK19(−)/MVI(−); 116 (33.0%), CK19(−)/MVI(+); 31 (8.8%), CK19(+)/MVI(−); and 51 (14.5%), CK19(+)/MVI(+). The disease-free survival of CK19(−)/MVI(−) patients was significantly higher than that of CK19(−)/MVI(+) patients and CK19(+)/MVI(+) patients. Similar results were observed for overall survival. CK19(+)/MVI(+) patients showed significantly lower overall survival than the other three groups.

Conclusions
CK19 expression and MVI predict poor prognosis after radical resection of HCC, and the two markers jointly contribute to poor OS. Combining CK19 and MVI may predict post-resection prognosis better than using either factor on its own.
Safety and efficacy of endovascular thrombectomy in acute ischemic stroke treated with anticoagulants: a systematic review and meta-analysis
Authors: Chen Jia-Hung , Hong Chien-Tai , Chung Chen-Chih , Kuan Yi-Chun , Chan Lung 
Published: June 2022

Abstract
Background
Endovascular thrombectomy (EVT) is an effective therapy in acute ischemic stroke (AIS) with large vessel occlusion, especially for those who are unsuitable for intravenous thrombolysis. However, the safety and efficacy of EVT in AIS patients who receiving oral anticoagulants (OACs) is unclear, especially for the risk of symptomatic intracranial hemorrhage (sICH).

Methods
Database of PubMed, Embase, and Cochrane Library were searched from Jan 1, 2000, through the final search date of Jun 2, 2021. Eligible studies for enrollment required outcomes reported for events of sICH, mortality, functional status, and successful reperfusion. Meta-analysis was conducted to compare the outcomes difference after EVT between AIS patients with or without OACs use. The primary safety outcome was sICH after EVT, and the primary efficacy outcome was functional status at 3 months.

Results
One thousand nine hundred forty studies were screened for eligibility and 15 of them were included in the meta-analysis. Compared the OACs group to control arm, vitamin K antagonists (VKAs) was associated with higher risk of sICH (OR 1.49, 95% CI 1.10–2.02) and mortality (OR 1.67, 95% CI 1.35–2.06). Poor functional outcomes were noted both in the VKAs and direct oral anticoagulants (DOACs) groups (OR 0.62, 95% CI 0.54–0.71 and OR 0.61, 95% CI 0.53–0.71, respectively). No differences in successful reperfusion were observed.

Conclusions
Comparing with DOACs, VKAs use was associated with a higher risk of sICH and mortality after EVT. Patients who did not receive OACs exhibited more favorable outcomes. The successful reperfusion did not differ between groups. However, results for mortality and functional outcomes have to be interpreted with caution since they are based on non-randomized data and unadjusted proportions.
Emotional blunting in patients with depression. Part III: relationship with psychological trauma
Authors: Christensen Michael Cronquist , Ren Hongye , Fagiolini Andrea 
Published: June 2022

Abstract
Background
This international online survey investigated the experience and impact of emotional blunting in the acute and remission phases of depression from the perspective of patients and healthcare providers (HCPs). This paper presents data on the history and severity of psychological trauma and its potential impact on emotional blunting in major depressive disorder (MDD); differences between patient and HCP perceptions are explored.

Methods
Patient respondents (n = 752) were adults with a diagnosis of depression who were currently taking antidepressant therapy and reported emotional blunting during the past 6 weeks. HCPs provided details on two eligible patients: one in the acute phase of depression and one in remission from depression (n = 766). Trauma was assessed using questions based on the Childhood Trauma Questionnaire; emotional blunting was assessed using the Oxford Depression Questionnaire (ODQ). Multivariate regression analyses were applied to examine the relationship between trauma and ODQ score.

Results
A history of any childhood or recent traumatic event was reported by 97% of patients in the self-assessed cohort and for 83% of those in the HCP-assessed cohort (difference, p < 0.01). Patients were more likely than HCPs to feel that this trauma had contributed to their/the patient’s depression (58% vs 43%, respectively; p < 0.01) and that the depression was more severe because of trauma (70% vs 61%, respectively; p < 0.01). Emotional blunting was significantly worse in patients who reported severe trauma than in those who had not experienced severe trauma (mean total ODQ score, 90.1 vs 83.9, respectively; p < 0.01). In multivariate regression analyses, experiencing both severe childhood and recent trauma had a statistically significant impact on ODQ total score (p = 0.001).

Conclusions
A high proportion of patients with depression and emotional blunting self-reported exposure to childhood and/or recent traumatic events, and emotional blunting was more severe in patients who reported having experienced severe trauma. However, history of psychological trauma in patients with MDD appeared to be under-recognized by HCPs. Improved recognition of patients who have experienced psychological trauma and are experiencing emotional blunting may permit more targeted therapeutic interventions, potentially resulting in improved treatment outcomes.

Authors: Agize Mathewos , Asfaw Zemede , Nemomissa Sileshi , Gebre Tizazu 
Published: June 2022

Abstract
Background
The study aimed at documenting the indigenous and local knowledge and use of traditional medicinal plants for treating human and livestock ailments in Dawuro Zone of Ethiopia.

Methods
A survey was conducted among traditional healers and native administrators through discussion, interviews, and field observations. The snowball sampling technique was used to select 384 traditional healers in purposefully selected 50 villages spanning seven districts for face-to-face individual interviews. The chi-square test was applied to establish associations between traditional healers’ demographics, the distance between the village site and the nearest natural forest and a health center, and SPSS V.20 software was used for the analysis.

Results
The traditional healers of the study area reported the use of 274 traditional medicinal plant species belonging to 217 genera and 82 families. Asteraceae (11.68%), Fabaceae (9.49%), and Lamiaceae (9.12%) were the foremost frequently used families. Herb species (54.8%) and leaves (65%) were predominantly sourced from the wild environment. The quantity of medicinal plants used (x2 = 278.368, df = 20, P = 0.000) and years of (experience in) traditional healing using herbs (x2 = 76.358, df = 10, P = 0.000) varied with distance from the natural forests. The service charge for healing had strong positive association (x2 = 24.349, df = 5, P = 0.000) with healer’s age (x2 = 309.119, df = 184, P = 0.000) and educational level (x2 = 851.230, df = 598, P = 0.000) with distance of traditional healer's residence from the medical institution. The agricultural activities, urbanization, low or no charge for the healing service, the secrecy and oral transfer of the knowledge, and the demand for medicinal and other multiple purposes species were some of the factors threatening the resource and the associated knowledge as well as the service in the study area.

Conclusion
There are diversified traditional medicinal plants applied for healthcare of the community and domestic animals of the study area. The source of remedies mostly depends on herbs of natural forests, and the leaf was the most frequently used plant part. Developing conservation intervention and sustainable systems of utilization is needed for multipurpose medicinal plants. Finally, integrating with modern system and formalizing, legalizing, and capacitating the traditional medicine practitioners are needed for access of primary healthcare systems to rural communities.
A comparison of ImageJ and machine learning based image analysis methods to measure cassava bacterial blight disease severity
Authors: Elliott Kiona , Berry Jeffrey C. , Kim Hobin , Bart Rebecca S. 
Published: June 2022

Abstract
Background
Methods to accurately quantify disease severity are fundamental to plant pathogen interaction studies. Commonly used methods include visual scoring of disease symptoms, tracking pathogen growth in planta over time, and various assays that detect plant defense responses. Several image-based methods for phenotyping of plant disease symptoms have also been developed. Each of these methods has different advantages and limitations which should be carefully considered when choosing an approach and interpreting the results.

Results
In this paper, we developed two image analysis methods and tested their ability to quantify different aspects of disease lesions in the cassava-Xanthomonas pathosystem. The first method uses ImageJ, an open-source platform widely used in the biological sciences. The second method is a few-shot support vector machine learning tool that uses a classifier file trained with five representative infected leaf images for lesion recognition. Cassava leaves were syringe infiltrated with wildtype Xanthomonas, a Xanthomonas mutant with decreased virulence, and mock treatments. Digital images of infected leaves were captured overtime using a Raspberry Pi camera. The image analysis methods were analyzed and compared for the ability to segment the lesion from the background and accurately capture and measure differences between the treatment types.

Conclusions
Both image analysis methods presented in this paper allow for accurate segmentation of disease lesions from the non-infected plant. Specifically, at 4-, 6-, and 9-days post inoculation (DPI), both methods provided quantitative differences in disease symptoms between different treatment types. Thus, either method could be applied to extract information about disease severity. Strengths and weaknesses of each approach are discussed.

Abstract
Background
Child and adolescent mental health problems are a global public mental health priority. However, there is a lack of evidence-based scalable psychological interventions for adolescents living in low resource settings. This trial was designed to evaluate the feasibility and acceptability of delivering the World Health Organization’s Early Adolescent Skills for Emotions (EASE) intervention at public schools in a rural sub-district in Rawalpindi, Pakistan.

Methods
A two arm, single blinded, feasibility cluster randomized controlled trial with mixed-methods evaluation was conducted with 59 adolescents and their caregivers from 8 public schools. In the 4 intervention arm schools, 6 non-specialist facilitators delivered the culturally-adapted EASE group sessions to the adolescents (n = 29) and their caregivers with desired fidelity under the supervision of in-country supervisors.

Results
The participation rate of adolescents in the intervention sessions was 83%. The intervention strategies were implemented by the adolescents. However, attending biweekly sessions at schools was challenging for caregivers with only 50% caregivers attending the sessions.

Conclusions
The results of this study support the feasibility and acceptability of delivering this culturally adapted intervention through non-specialist facilitators in school settings in Pakistan and pave the way to conduct a fully powered cluster randomized controlled trial to test the effectiveness of intervention to improve psychological outcomes in adolescents.

Published: June 2022

AbstractInflammatory bowel disease (IBD), a chronic gut immune dysregulation and dysbiosis condition is rapidly increasing in global incidence. Regardless, there is a lack of ideal diagnostic markers, while conventional treatment provides scarce desired results, thus, the exploration for better options. Changes in the gut microbial composition and metabolites either lead to or are caused by the immune dysregulation that characterizes IBD. This study examined the fecal metagenomics and metabolomic changes in IBD patients. A total of 30 fecal samples were collected from 15 IBD patients and 15 healthy controls for 16S rDNA gene sequencing and UHPLC/Q-TOF-MS detection of metabolomics. Results showed that there was a severe perturbation of gut bacteria community composition, diversity, metabolites, and associated functions and metabolic pathways in IBD. This included a significantly decreased abundance of Bacteroidetes and Firmicutes, increased disease-associated phyla such as Proteobacteria and Actinobacteria, and increased Escherichiacoli and Klebsiellapneumoniae in IBD. A total of 3146 metabolites were detected out of which 135 were differentially expressed between IBD and controls. Metabolites with high sensitivity and specificity in differentiating IBD from healthy individuals included 6,7,4′-trihydroxyisoflavone and thyroxine 4′-o-.beta.-d-glucuronide (AUC = 0.92), normorphine and salvinorin a (AUC = 0.90), and trichostachine (AUC = 0.91). Moreover, the IBD group had significantly affected pathways including primary bile acid biosynthesis, vitamin digestion and absorption, and carbohydrate metabolism. This study reveals that the combined evaluation of metabolites and fecal microbiome can be useful to discriminate between healthy subjects and IBD patients and consequently serve as therapeutic and diagnostic targets.
Immediate effect of trunk flexion and extension isometric exercise using an external compression device on electromyography of the hip extensor and trunk range of motion of healthy subjects
Authors: Huang Tian-zong , Kim Suhn-yeop 
Published: June 2022

Abstract
Background
Sacroiliac joints (SIJs) transmitted trunk load to lower extremities through the lumbopelvis. External compression devices across the SIJs could provide stability to the SIJs. A previous study established that using a device known as Active Therapeutic Movement version 2 (ATM®2) has been developed to improve pain and joint range of motion (ROM) in patients with LBP. However, no study has examined the physiological change in the muscle through ATM®2-based exercise thus far. This study aimed to determine the immediate effects of ATM®2 exercise on the contraction timing, back extension endurance, muscle fatigue, and trunk ROM of lumbar and lower limb muscles in healthy subjects.

Methods
Thirty-six healthy subjects (mean age = 23.16 ± 2.3) volunteered to participate in this study. Subjects were instructed to perform ROM test using sit and reach test, back extensor endurance test using Biering-Sorensen test, erector spinae (ES), lumbar multifidus (LM) fatigue and onset time of Gluteus maximus (GM) in prone hip extension using electromyography before and after trunk flexion and extension isometric exercises.

Results
The ROM in trunk flexion showed a significant increase of 7.9% after exercise compared to that before exercise (p < 0.05). Relative GM contraction onset timing significantly decreased after exercise (p < 0.05). The result of the Sorensen test after exercise showed a trend of increase in duration time. Muscle fatigue in the LM, however, showed a significant increase (p < 0.05), whereas muscle fatigue in the ES was reduced without statistical significance.

Conclusions
The results base on this study showed that exercise-based on ATM®2 is an effective exercise protocol with an effect on the biomechanics of healthy subjects.

Multicomponent exercises to prevent and reduce back pain in elderly care nurses: a randomized controlled trial
Authors: Otto Ann-Kathrin , Wollesen Bettina 
Published: June 2022

Abstract
Background
Sports science is making an important contribution to health services research and supports the development of tailored interventions, e.g., in nursing settings. Working in elderly care is associated with a high prevalence of low back pain (LBP). Due to the diverse requirements and high strains, multicomponent programs are essential to address all relevant factors. This randomized controlled trial investigated the effects of a tailored ten-week ergonomics and twelve-week strength training on lifting behavior, strength endurance, LBP, functional impairment and adherence.

Methods
n = 42 nurses were randomly assigned to the intervention (IG; n = 20) or control group (CG; n = 22). They were eligible for participation if they were active in residential care and if they provided written informed consent. Other employees were excluded. The data were collected at baseline, at ten weeks (after ergonomics training), at 22 weeks (after strength training), and at 34 weeks (follow-up). The analysis combined physical tests with questionnaires (Progressive Isoinertial Lifting Evaluation, PILE-Test; Biering-Sørensen-Test; Visual Analog Scale Pain, VAS; Oswestry Disability Index, ODI; self-developed questionnaire for adherence). Group differences were analyzed by Chi2-Tests, ANOVA, and Linear Mixed Models.

Results
The IG showed an improved lifting performance (PILE-Test; 95% CI 1.378–7.810, p = .006) and a reduced LBP compared to the CG (VAS; 95% CI − 1.987 to 0.034, p = .043) after ergonomics training (PILE-Test, F(1,34) = 21.070, p < .001; VAS, F(1,34) = 5.021, p = .032). The results showed no differences concerning the Biering-Sørensen-Test and the ODI. Positive adherence rates were observed.

Conclusions
This approach and the positive results are essential to derive specific recommendations for effective prevention. The study results can be completed in future research with additional strategies to reduce nurses’ burden further.
