Authors: Wu Yu , Su Binbin , Zhao Yihao , Chen Chen , Zhong Panliang , Zheng Xiaoying 
Published: April 2023

Abstract

Background
The prevalence and associated factors of suicidal ideation (SI) among the elderly in China varied widely between studies. This meta-analysis firstly aimed to show the epidemiological features of SI among the elderly in China.
Methods
Relevant databases, including English and Chinese, were systematically searched from database inceptions until September 15, 2022. Data included literature were used to calculate the prevalence and odds ratios (OR) of associated factors regarding SI among Chinese elderly.
Results
31 cross-sectional studies including 79,861 subjects, covering over 20 provinces and cities in China, were included for final analysis from 7591 potential studies. The pooled prevalence of SI among the elderly in China was 11.47% (95% CI 7.82–15.71%). Prevalence significantly varied based on residence, physical (chronic disease, activities of daily living disability, health status), mental (depression symptoms and life satisfaction), economic condition, and measuring tools with time points. It should be noted that the pooled prevalence in 2011–2020 (15.59%, 95% CI 9.08–23.44%) is nearly twice as high as that in 2001–2010 (7.85%, 95% CI 5.08–11.16%). Besides, 14 factors with a pooled OR>1 (p<0.05) and 2 factors with a pooled OR<1 (p<0.05) affecting SI significantly in Chinese elderly were found.
Conclusion
The prevalence of SI among Chinese elderly may be relatively high, presenting diverse distributional characteristics and associated factors. Therefore, more targeted programs are imperative to manage elderly-related suicide. Standard measuring tools with narrow time points for SI is equally necessary.

Published: April 2023

Abstract
Background. Chronicity and lack of motivation often go together during the upper limb rehabilitation process in stroke. Virtual reality is a useful tool in this context, providing safe, intensive, individualised treatments in a playful environment. Low-cost, easy-to-use devices with personalised and motivating games for a specific population seem to be the most effective option in the treatment of the upper limbs.
Methods. A randomised clinical study with follow-up was carried out to assess the effectiveness of the Leap Motion Controller® device in improving the functionality of the upper limb in patients with chronic stroke. Patients (n=36) were randomised into a control group that performed conventional therapy and an experimental group that combined the virtual reality protocol with conventional therapy. The outcome measures used were grip strength; the Block and Box Test; the Action Research Arm Test; the Disabilities of the Arm, Shoulder and Hand; as well as a Technology Satisfaction Questionnaire and adherence to treatment.
Results. Inter-group statistical analysis showed no significant differences except in subsection D of the Action Research Arm Test. Intra-group analysis showed significant differences in both groups, but the experimental group reached significance in all long-term variables. Satisfaction and adherence levels were very high.
Conclusions. The Leap Motion Controller® system, as a complementary tool, produces improvements in grip strength, dexterity and motor function in patients with chronic stroke. It is perceived as a safe, motivating, and easy-to-use device.

Current Methods in The Surgical Treatment of Hemorrhoids
Authors: Sakoglu Nevin 
Published: April 2023

Abstract
PURPOSE: Hemorrhoidal disease is a chronic disease of the lower rectum and anus because of increased pressure during straining. Millions of people around the world suffer from this disease. My aim here was to see with the non-surgical method could we achieve the success achieved with the surgical method, which could cause serious complications.METHODS: We compared two different treatment methods; surgical (Longo) technique and less invasive non-surgical (ADL) methods by examining the post-operative pain complaints and normal daily activities of our patients operated for hemorrhoids retrospectively. Patients operated for hemoroid from 2021 to 2022 were included.RESULTS: A total of 120 patients, sypmtomatic with bleeding per rectum included in this study. There was no statistically significant difference between the age and gender distributions of the Longo and ADL groups (p = 0,231, p = 0,711). When the daily activities of both groups were compared, the dressing(p = 0.042) and toileting (p = 0.012) activities in the Longo group were found to be statistically significantly lower than the ADL group. On the other hand there was a statistically significant difference within the groups (Longo; p = 0,0001, ADL; p = 0,0001) related to the pain assessments at the end of the 1st day, 1 week and 1 month.CONCLUSION: When both methods were compared, the adaptation of the ADL group to normal daily life was faster than the Longo group. I only detected tenesmus complaint in 12 stage III-IV patients whom I had the pexy procedure (n = 12) (20%).
Molecular evidence about ancestral origin, colonization patterns, and phylogenetic diversity of Coffea arabica, with insights in Latin America

Published: April 2023

Abstract
Coffee is one of the most widely consumed agricultural products worldwide. The most well-known coffee species in the market are Coffea arabica and Coffea canephora. Currently, 42 varieties are recognized within C. arabica, but strangely, with very low levels of intraspecific genetic diversity despite its worldwide geographical distribution. In addition, little is known about its phylogeographical history. Although there exist descriptive hypotheses of worldwide colonization patterns and origin for C. arabica (by Ferreira et al. in 2019), none of them are molecularly supported. In this study, data mining and bioinformatic approaches, allowing to collect DNA sequences of the Internal Transcribed Spacer (ITS) region available up to date. All sequences were analyzed under the Relaxed-Random-Walk (RRW) methodology, aiming to estimate ancestral areas and spatiotemporal dispersion patterns, with South American insights. ITS was also used with Single Locus Species Discovery (SLSD) methodology, which allows the delimitation of putative lineages/species (cryptic diversity). RRW supported that the origin and the genetic diversity center of C. arabica species took place between Ethiopia and South Sudan. The study also found evidence of five colonization events and the dispersion of the species within Latin America. SLSD estimated two to 12 cryptic lineages/species within C. arabica depending on the algorithm used; with Latin America being home to two to six of these lineages. The results suggest that the evolutionary history and global dispersion of C. arabica is more complex than historians have registered, showing intermediary regions and ancestors unpublished nowadays, as well as a cryptic diversity being underestimated.
Is the Incidence of Eating Pathology and Intense Body Dissatisfaction in poorer communities of color comparable to national incidence?
Authors: Woodland Stacie Leev , Lufkin Kate P. 
Published: April 2023

Abstract

Background: Communities of color have been under-assessed and under-diagnosed with eating disorders. Most of the previous research on BIPOC communities has focused mainly on eating pathology as it relates to food insecurity. The purpose of this study was to explore whether the incidence of eating pathology and intense body dissatisfaction in poorer communities of color was comparable to the incidence reported by the National Institute of Mental Health and National Eating Disorder Association. The data outcomes may be relevant to community based mental health clinics and their partners as it will potentially highlight gaps in research, diagnostic assessment, and treatment interventions specific to eating disorders in marginalized communities.
Methods: The data was collected from 309 individuals seeking mental health treatment in a community based mental health clinic in East Harlem NYC. Two separate assessments were utilized. The first assessment was conducted at intake within the comprehensive psychosocial assessment. It was a self-reported measure that assessed frequencies of 5 types of eating pathology: 1.) restricting, 2.) restricting/binging 3.) restricting/purging, 4.) binge/purging, and 5.) binging. Body and Weight Attitude Likert assessment scale, a 14-item measure was created based on 5 sub-scales: 1.) income 2.) restricting eating and obsessive thought behavior 3.) body dissatisfaction 4.) binge-eating and compensatory behavior 5.) emotional distress.
Results: This is the first study to investigate rates of eating pathology and attitudes around body image and weight in a poorer community with the majority of the community identifying as people of color. What we found was high rates of body dissatisfaction and high incidence of eating pathology which is not only comparable to the NIMH and NEDA’s data for a white population but is higher than what the current data supports for any racialized group. Our data also shows higher rates of eating disorder diagnosis, particularly for AN, AAN, and EDNOS than what is supported in either NIMH and NEDA for any racialized group We discovered the incidence of frequency of restricting food was highest in the Black and mixed-Race participants. Black participants had the highest rate of diagnosis of an eating disorder of restricting type, which is much higher than the national incidence. Body dissatisfaction is the most notable risk factor in the development of eating disorders. The mixed-race group (n=97) rated highest on intensity of body dissatisfaction. This study highlights the need for further investigation, so we don’t perpetuate the neglect of these communities in both mental and medical health care.

Abstract
Background: Needs assessment tools may guide optimisation of clinical services to be more patient-centred. As needs of patients living with and beyond colorectal cancer (CRC) may also be influenced by socio-cultural backgrounds and healthcare ecosystems, we developed and validated a needs assessment questionnaire for CRC in a multiethnic, low and middle-income setting.
Method: Study methodology was guided by the COSMIN checklist. Items generation was based on findings from independent qualitative inquiries with patients, input from cancer stakeholders, and literature review. Following translation into Malay language, content and face validation were undertaken. The tool was administered to 300 individuals living with and beyond CRC. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. Criterion validity was assessed using EORTC QLQ-C30 and QLQ-CR29 questionnaires.
Result: The 48-item bilingual needs assessment tool for colorectal cancer (NeAT-CC) encompassed six domains of needs, namely diagnosis, psychosocial and information, healthcare, practical and living with cancer, financial, and employment. Cronbach’s alpha was above 0.70 for all domains, indicating good internal consistency. CFA also demonstrated acceptable convergent and divergent validity with composite reliability >0.70 and Heterotrait–Monotrait index <0.90 for all constructs. Criterion validity was established given the significant negative correlation with quality of life. The NeAT-CC was easily understandable, took 15-20 minutes for completion and may be self-administered.
Conclusion: Utilisation of NeAT-CC may enable optimisation of supportive and survivorship care services following CRC in local settings. The tool has wider potential for adaptation in other multiethnic and/or low and middle-income settings.
Functional Mitochondrial Depletion in Non-cancer Cells Caused by Beneficial Mitochondria Exchange for Cancer Cells is the Direct Cause of Death by Cancer
Authors: Tang Michael , Zhou Guangyi 
Published: April 2023

Abstract
The most important question for cancer is not how cancers form or how metastasis occurs, it is how metastatic cancer causes death. This paper proposed a theory to answer this question. Fast-proliferating cancer cells require more energy which is mainly produced by the respiration of mitochondria. However, respiration in mitochondria is not sustainable because the high level of reactive oxygen species (ROS) is produced during respiration and damages mitochondria through oxidization. As a result, to meet the long-lasting and high level of energy requirement, cancer cells use up their own mitochondria, and release the used, damaged, or oxidized mitochondria to, and acquire functional, undamaged, or unoxidized mitochondria from surrounding non-cancer cells. This beneficial mitochondria exchange for cancer cells is facilitated by metastasis, because metastatic foci are much smaller than the original tumor, providing a much larger contact surface between a given number of cancer cells and the surrounding non-cancer cells. The beneficial mitochondria exchange for cancer cells keeps repeating, and gradually leads to functional mitochondria depletion in non-cancer cells, most importantly in cells of vital organs such as the brain and the heart. As a result, it leads to a lack of energy in vital organs and eventually death of the patient. This theory was supported by three key results: First, mitochondria from the brain or heart of late-stage liver cancer or prostatic cancer mice showed decreased respiration rate; Second, metastatic liver cancer cells in the lung transfer their mitochondria to surrounding cells. Lastly, the administration of functional mitochondria to prostatic cancer mice increased their survival.

Abstract
Background The measurement of the experience perceived and reported by patients and families is essential to improve the care process. In the literature, a wide variety of questionnaires and supra-specialized scales are provided for services, pathologies or areas of care, making it difficult to compare their results. Our objective was to design and psychometrically validate a questionnaire to measure the experience of patients treated in hospitals and outpatient services and possibly virtual services.Method This was a survey and validation study of instruments with adult patients treated in eight clinics and 28 medical centers. The QEx-P Questionnaire was designed and administered electronically. Construct validity was evaluated with AFE and CFA; convergent and discriminant validity with Spearman's coefficient and Fornell's criterion, respectively; and reliability with Cronbach's alpha.Results A total of 2972 surveys were analyzed. In the validation of the construct, 12 models were estimated, finding a better goodness of fit in the 5-factor models for outpatient and hospital care and 1-factor for virtual care. The convergent validity showed a moderate correlation with the NPS. The discriminant validity was indeterminate. Reliability showed high internal consistency.Conclusion The questionnaire designed and validated in this study has psychometric validity and reliability as a tool to measure the experience reported by Spanish-speaking patients attended in outpatient and hospital services, in addition to being potentially useful for measurement in virtual services (calls or telehealth).
ASViS: A Protocol for Efficient Video Streaming Using SVC and Deadline-based Criteria.

Published: April 2023

Abstract
Multimedia video streaming is the most used data consumption service on the Internet. Maintaining a data flow rate that provides the best video quality possible without overflowing the pipeline is challenging. Dynamic Adaptive Streaming over HTTP (DASH) is a commonly used protocol that sends video data in small packages called chunks. However, this technique can lead to video buffering issues and video pausing due to an empty video buffer. Adaptive Scalable Video Streaming (ASViS) is a more versatile protocol that uses scalable video coding, a flow-controlled user datagram protocol (UDP), and deadline-based criteria to manage the buffered data. Like transmission control protocol (TCP), ASViS adjusts the flow based on available bandwidth, and it can discard data based on video frame deadlines to prevent outdated data transmission. ASViS is compliant with RFC 8085, preventing it from overwhelming the Internet. The scalability feature allows ASViS to have the highest image quality possible in every frame allowed by SVC with the data layers available. A theoretical model is presented that predicts ASViS behavior under different network conditions. This work also shows how different parameters affect its performance and how it can be easily configured to optimize it.
Analysis of the Variation of the Mechanical Properties of a LLDPE Matrix by Incorporation of Reused XLPE
Authors: Loureiro Nuno , Granja J. , Lopes R. , Rocha M. 
Published: April 2023

Abstract
XLPE is a thermoset polymer used by ALCOBRE to insulate cooper wires. The wastes of this polymer can’t be discarded in the regular industrial waste and all the wastes costs of this material are expensive. The XLPE needs to be segregated and then a certified waste company transports this waste to identified dumping areas. In this work we try to study the incorporation of the XLPE on a LLDPE matrix.The LLDPE is a thermoplastic polymer used by ALCOBRE to coat copper wires.In this work the mechanical behaviour of XLPE/LLDPE blends is investigated in a wide range of compositions. The mechanical properties can be optimized by varying the XLPE contents of the blend. The flexural and tensile properties were estimated by different models: the rule of mixtures, Kerner-Uemura-Takayanagi model, and Nicolai-Narkis model. This work also considers the adhesion between the two material phases. The results anticipate a good adhesion between both phases. For the tensile modulus, a linear relationship is found, which indicates a good adhesion between the phases along the composition range. The increase of XLPE in the mixture decreases the bending and tensile stress. For tensile stress, the Nicolai-Narkis model is suitable for modelling behaviour by inducing good adhesion between phases. In relation to the module, it is possible to verify that in relation to the bending module the incorporation of XLPE does not affect the module. However, the traction module will be affected with the XLPE quantity in the mixture.
Effect of Raw Pectin Amendment on The Survival and Proliferation of Azospirillum in Non-Sterile Soil
Authors: Mehanni Magda M. , Mahmoud Hasnaa A. 
Published: April 2023

Abstract
TWO STRAINS of plant growth-promoting (PGPR) bacterium Azospirillum were isolated as endophytes from roots of wheat seedlings grown in the spermosphere model that was inoculated with aliquots of two rhizosphere soil samples. Azospirillum isolate 3Re was recovered after inoculation with Sisamum irio rhizosphere soil and the other isolate (1Rr) was recovered after inoculation with rhizosphere soil from Faculty of Science's botanical garden at Minia University that was planted with Allium cepa. One of the physiological studies on those Azospirillum strains exhibited that they have a pectinolytic activity. The present study aims to evaluate the effect of these locally isolated Azospirilla inoculation into a raw pectin amended soil, cultivated with Zea mays seedlings, on their population densities in rhizosphere and free soils and how far this could affect some of Zea mays growth parameters. The investigation was carried out in pot experiments using non-sterile clay soil. The most important observation in this study was that the viable Azospirillum counts in raw pectin amended free soil is equal to that of the un-amended rhizosphere soil which could indicate that the most valuable nutrient that Azospirillum could gain from root exudates is the utilizable carbon, and when it supplied to the free soil, the population number reaches that of the rhizosphere soil without the need to any other supplementation.
A novel safety assessment of the building vibration evolution undergoing a disastrous earthquake
Authors: Shih David Ching-Fang , Wu Yih-Min 
Published: April 2023

Abstract
It designs a disastrous earthquake as the referenced event, the known Chi-chi earthquake (1999) in Taiwan, to characterize and compare a monitored displacement of a building before and after that event. It suggests that period and damping nearly increase as the magnitude increases for the smaller distance between the building and the hypocenter. After the earthquake, it can regress the estimated best period as a function of PGA. This research performs a practical assessment of the natural vibration of a building to an attic-basement system for long-term observation of earthquake activities. It presents a novel and realistic evaluation of the natural vibration of a building under disastrous earthquake activities. Assessing building vibration evolution using historical long-term strong motion data before and after a devastating earthquake to check a building's status can be feasible and reachable. The result provides relevant safety arguments for future maintenance.
Bank’s strategic interaction, adverse price dynamics, and systemic liquidity risk
Authors: Krüger Ulrich , Roling Christoph , Silbermann Leonid , Wong Lui-Hsian 
Published: April 2023

Abstract
In this paper, we introduce two measures, the Systemic Liquidity Buffer (SLB) and the Systemic Liquidity Shortfall (SLS), to assess liquidity in the banking system. The SLB takes an aggregated perspective on liquidity risks in the banking system. In contrast, the SLS focuses on the problematic banks which suffer a liquidity shortfall. These measures provide an add-on to regulatory liquidity measures such as the LCR because they better incorporate a systemic perspective: (1) They model the impact of a funding shock by valuing assets at depressed market prices, (2) Doing so, they explicitly incorporate banks’ strategic responses to a market undergoing sharp price declines. We test our approach using several applications capturing both a short (5 days) and a medium-term (30 days) stress scenario, a sudden rise in interest rates, the impact of banks’ US dollar business, and the recent COVID-19 crisis.
