Abstract
Introduction
Hand hygiene compliance is the problem of developing nations particularly in Sub-Saharan Africa including Ethiopia. Despite a lot of efforts have been employed, healthcare-associated infections are the existing health care problems, leading to impaired quality of life, prolonged hospital stays, increased healthcare costs, morbidity and mortality. This study aimed to assess the magnitude and factors associated with hand hygiene compliance among health care providers working at the primary hospitals of Waghimira Zone, Northeast Ethiopia.

Methods
Facility-based cross-sectional study design supplemented with qualitative research method was employed at the primary hospitals of Waghimira Zone from March 02–15, 2020. Simple random sampling using lottery method was applied to select 253 study participants. The data were coded on pre-arranged coding sheet and entered into Epi-Data version 3.1 and exported to SPSS version 25 for analysis. Descriptive statistics were displayed using tables and figures. Binary logistic regression analysis was used to test associations between the independent and the outcome variable. Multivariable logistic regression analysis was fitted to identify the independent predictors of hand-hygiene compliance at p-value < 0.05 and AOR with 95% confidence interval. Six Key Informant Interviews were conducted with purposively selected chief executive and clinical officers. Thematic content analysis was made and the findings were written sequentially with explanatory method.

Results
One-fifth of the subjects (20.6%, 95% CI = 15.2, 24.9) had good hand hygiene compliance. Attended training on hand hygiene protocol (AOR = 3.18, 95% CI: 1.39, 7.28), accessible to adequate soap and water (AOR = 3.77, 95%CI: 1.52, 9.37), having alcohol for hand rub (AOR = 2.67, 95%CI: 1.18, 6.05) and having hand wash sink (AOR = 2.31, 95%CI: 1.03, 5.14) were significantly associated with hand hygiene compliance which also supported by the qualitative findings.

Conclusions
Hand hygiene compliance among health care providers was low in the study area. Attended training on hand hygiene, accessibility to adequate soap and water, alcohol-based hand rub, and having hand washing sink in working area were statistically significant. Hence, the primary hospitals should be equipped with adequate supply to all the basic hand hygiene facilities.
Intratumor microbiome in cancer progression: current developments, challenges and future trends
Authors: Liu Jinyan , Zhang Yi 
Published: May 2022

AbstractCancer is a complicated disease attributed to multifactorial changes, which causes difficulties with treatment strategies. Various factors have been regarded as the main contributors, and infectious etiological factors have recently attracted interest. Several microbiomes contribute to carcinogenesis, cancer progression, and modulating cancer treatment by inducing cancerous epithelial cells and chronic inflammation. Most of our knowledge on the role of microbiota in tumor oncogenesis and clinical efficiency is associated with the intestinal microbiome. However, compelling evidence has also confirmed the contribution of the intratumor microbiome in cancer. Indeed, the findings of clinical tumor samples, animal models, and studies in vitro have revealed that many intratumor microbiomes promote tumorigenesis and immune evasion. In addition, the intratumor microbiome participates in regulating the immune response and even affects the outcomes of cancer treatment. This review summarizes the interplay between the intratumor microbiota and cancer, focusing on the contribution and mechanism of intratumor microbiota in cancer initiation, progression, and potential applications to cancer therapy.

Published: May 2022

AbstractCoral reefs are very important ecosystem which are the foundation of all life on this earth, but now they are under threat. Coral bleaching are happening now at a serious rate and the ultimate goal of conservation effort toward this issue is behaviour change. One of the most important parts of conservation effort is monitoring. However, monitoring the success of the coral bleaching campaign on behaviour change requires extensive data collection so traditional methods are not effective because they require resources that may not be met. The goal of this study is to build fast and vast automation in analyzing the stage of behaviour change. Social media data has prospect to become good alternative to be used because social media usage is currently increasing every year, including Twitter. Therefore, an automatic classification model was designed which can identify the stages of behaviour change based on the Five Doors Theory on Twitter. Five Doors Theory define 5 stages of behavior change: Desirability, Enabling Context, Can Do, Buzz, and Invitation. The data was fetched through a trusted repository, Mendeley Data, with title "An Annotated Dataset for Identifying Behaviour Change Based on Five Doors Theory Under Coral Bleaching Phenomenon on Twitter". There are 1,222 tweets with keywords related to coral bleaching that have been annotated according to the behaviour change stages. There are two proposed designs: embedding extraction which utilizes the output of each encoder layer in BERTweet and stacking ensemble which uses several BERTweet models with different hyperparameters that are ensembled using a logistic regression model. The best accuracy of 0.7796 with an f1-score of 0.7945 was obtained in the stacking ensemble design scenario. The classification model created can identify each class at the stage of behaviour change well, even though the dataset is unbalanced in its distribution. The proposed design has a performance that exceeds all baseline models and the standalone BERTweet. In conclusion, the automatic classification model create the process of monitoring the stages of behavior change run effectively and efficiently so that the success of the coral bleaching campaign can be monitored and achieved.

Published: May 2022

Abstract
Background
CT has been used on a massive scale to help identify and investigate suspected or confirmed cases of COVID-19 pneumonia. This study aimed to assess the prognostic significance of the chest findings MSCT of COVID-19 patients and to determine if prognosis can rely on the initial CT imaging.

Methods
The study design was retrospective cohort study. It was carried out on 300 patients presented to the chest outpatient clinics in Benha University hospitals and El Abbassia Chest Hospital with clinical picture suggestive of COVID-19 infection. The CT finding were then compared to the short-term clinical outcome of the patients (1–3 weeks), acquired from the hospital patient data archive. According to the progression of the respiratory symptoms (including dyspnea, respiratory rate, and O2 saturation), the short-term clinical outcome of the patients was classified into 4 groups: group A (mild cases), group B (moderate cases), group C (severe cases), and group D (fatality cases).

Results
Consolidations, septal thickening, crazy paving, and fibrotic bands were significantly higher in groups C and D than group A and B (P-value < 0.001 for all variants). Nodules show statistically significant higher incidence in groups A and B than group C and D (P-value < 0.001). The CT severity score shows statistically significant increase with the poor short-term clinical outcomes (groups C and D) (P-value < 0.001).

Conclusion
CT chest is a good radiological marker that can help in predicting short-term clinical outcome in COVID-19 patient. Higher CT severity scores are predictors of poorer clinical prognosis.
Evidence of learning walks related to scorpion home burrow navigation
Authors: Gaffin Douglas D. , Muñoz Maria G. , Hoefnagels Mariëlle H. 
Published: May 2022

ABSTRACTThe navigation by chemo-textural familiarity hypothesis (NCFH) suggests that scorpions use their midventral pectines to gather chemical and textural information near their burrows and use this information as they subsequently return home. For NCFH to be viable, animals must somehow acquire home-directed ‘tastes’ of the substrate, such as through path integration (PI) and/or learning walks. We conducted laboratory behavioral trials using desert grassland scorpions (Paruroctonus utahensis). Animals reliably formed burrows in small mounds of sand we provided in the middle of circular, sand-lined behavioral arenas. We processed overnight infrared video recordings with a MATLAB script that tracked animal movements at 1–2 s intervals. In all, we analyzed the movements of 23 animals, representing nearly 1500 h of video recording. We found that once animals established their home burrows, they immediately made one to several short, looping excursions away from and back to their burrows before walking greater distances. We also observed similar excursions when animals made burrows in level sand in the middle of the arena (i.e. no mound provided). These putative learning walks, together with recently reported PI in scorpions, may provide the crucial home-directed information requisite for NCFH.

Abstract
Multi-metallic inorganic alloy materials have attracted great attention recently. Additionally, molecule-based materials have wide designability in terms of their structures and electronic states. These are two different ideas. Here, we report the mixing of Pd(III) and Au(III) ions into a bromide-bridged molecular chain compound [Ni(chxn)2Br]Br2 (chxn: 1R,2R-diaminocyclohexane) to form an average formula of [Ni0.853Pd0.142Au0.005(chxn)2Br]Br2, which was synthesized by an electrochemical oxidation method. This trimetallic material is revealed to be a Mott–Hubbard state semiconductor with a one-dimensional electronic system like that of [Ni(chxn)2Br]Br2, whereas it shows a smaller activation energy for conductivity than that of pristine [Ni(chxn)2Br]Br2. This work represents a fusion of the concepts of multi-metallic and molecule-based materials using a 1D compound.

Published: May 2022

Background - Since 2016, the Securities Commission (SC) in Malaysia has given licenses to only eleven P2P lending platforms. Such lending platforms are expected to disrupt the lending services of traditional lenders in the coming years. However, being still in their infant stages, it is essential to know the extent to which such platforms are made known to potential investors out there. This study aims to examine the awareness level of the eleven P2P lending platforms among Malaysian adults. The study also explores if past investment experience and financial knowledge would influence such awareness from Malaysian adults. Methods - A sample of 335 Malaysian individuals was used for this study. An online questionnaire was designed with three main parts: demographic, financial literacy, and P2P lending awareness. Using IBM SPSS Statistics 26, frequency, descriptive, normality, Pearson coefficients and multiple regression analyses were carried out. Results - Although seven out of ten respondents have good knowledge in three areas of finance: compounding rate, inflation and diversification, only 14.33% had a good and excellent awareness level of P2P lending. Thus, one would expect lesser awareness about P2P lending among Malaysian adults whose financial literacy is poor or zero. Test results from multiple regression analysis suggest that past lending experiences positively affect the awareness of P2P lending in Malaysia, but not the financial literacy. Conclusions - the awareness about P2P lending among Malaysian adults is too low, despite their high level of education and financial literacy. No investing experience and not knowing any existing P2P lending in the country may be the reason for this low awareness. Therefore, for P2P lending to thrive in Malaysia, the eleven P2P lending platforms need to be promoted aggressively in various social media outlets.
The lifetime revision risk of unicompartmental knee arthroplasty
Authors: Tay Mei L. , Young Simon W. , Frampton Christopher M. , Hooper Gary J. 
Published: May 2022

Aims Unicompartmental knee arthroplasty (UKA) has a higher risk of revision than total knee arthroplasty (TKA), particularly for younger patients. The outcome of knee arthroplasty is typically defined as implant survival or revision incidence after a defined number of years. This can be difficult for patients to conceptualize. We aimed to calculate the ‘lifetime risk’ of revision for UKA as a more meaningful estimate of risk projection over a patient’s remaining lifetime, and to compare this to TKA. Methods Incidence of revision and mortality for all primary UKAs performed from 1999 to 2019 (n = 13,481) was obtained from the New Zealand Joint Registry (NZJR). Lifetime risk of revision was calculated for patients and stratified by age, sex, and American Society of Anesthesiologists (ASA) grade. Results The lifetime risk of revision was highest in the youngest age group (46 to 50 years; 40.4%) and decreased sequentially to the oldest (86 to 90 years; 3.7%). Across all age groups, lifetime risk of revision was higher for females (ranging from 4.3% to 43.4% vs males 2.9% to 37.4%) and patients with a higher ASA grade (ASA 3 to 4, ranging from 8.8% to 41.2% vs ASA 1 1.8% to 29.8%). The lifetime risk of revision for UKA was double that of TKA across all age groups (ranging from 3.7% to 40.4% for UKA, and 1.6% to 22.4% for TKA). The higher risk of revision in younger patients was associated with aseptic loosening in both sexes and pain in females. Periprosthetic joint infection (PJI) accounted for 4% of all UKA revisions, in contrast with 27% for TKA; the risk of PJI was higher for males than females for both procedures. Conclusion Lifetime risk of revision may be a more meaningful measure of arthroplasty outcomes than implant survival at defined time periods. This study highlights the higher lifetime risk of UKA revision for younger patients, females, and those with a higher ASA grade, which can aid with patient counselling prior to UKA.

Published: May 2022

<p align="justify">Sentiment analysis on unbalanced data will cause classification errors where the classification results tend to be in the majority class. Therefore, it is necessary to handle unbalanced data. In this study, a combination of synthetic minority oversampling technique (SMOTE) and Tomek link methods will be used to handle unbalanced data. In this study, we use the Recurrent Neural Network (RNN) method to analyze the sentiment of Shopee application users based on review data. Shopee Indonesia application review data shows that around 80% of Shopee application users have positive sentiments and 20% have negative sentiments, which means the data is not balance. In this study, preprocessing process with combination of synthetic minority oversampling technique (SMOTE) and Tomek link method used to handle the condition. The performance of the result is quite good, namely 80% accuracy, 84.1% precision, 92.5% sensitivity, 30% specificity, and 88.1% F1-score. It is better than performance of sentiment analysis that without preprocessing to handle imbalanced data.</p><p><strong>Keywords</strong><strong>: </strong>sentiment analysis; imbalanced data; Tomek link; SMOTE; RNN</p>
Management of idiopathic granulomatous mastitis: a prospective study
Authors: Sarkar DK , Banerjee R , Gupta S , Singhal AK , Halder A 
Published: May 2022

Introduction Idiopathic granulomatous mastitis (IGM) is an evolving problem with varied presentation. No definite treatment guidelines are available at present that may reduce rate of recurrence. Current evidence suggests a ductal pathology behind IGM, which leads to periductal mastitis, leakage and sinus/fistula formation. Thus, excision of the sinus/fistulous tract with en-bloc wide local excision (WLE) of the lesion could be curative. The objective of this study was to look for the basic aetiology of IGM and evaluate the effectiveness of WLE with total or partial duct excision as a curative approach. Methods An institutional prospective comparative study was conducted over 4 years (2015–2019), in which 59 cases of IGM were randomly divided into three groups. After necessary investigations, patients in group A received steroid therapy, those in group B received WLE and patients in group C received WLE with total or partial duct excision as the mode of treatment. Postoperative follow-up was between 6 months and 3 years. Results Histopathological examination (HPE) was found to be the most suitable diagnostic procedure. Patients in group B showed the highest rate of recurrence (73.6%), followed by group A (35.0%) and group C (5.0%). Patients in group C had a significantly lower chance of recurrence compared with both group A and group B (p < 0.05). HPE reports of excised ducts from patients in group C showed ductal disruption and leakage along with periductal granuloma in 70% of cases. Conclusions The presence of duct granuloma indicates the association of ductal pathology in IGM. IGM is therefore a disease of the mammary ducts and en-bloc duct excision is curative in non-responding cases.
Conception of a single-component broadband high-resolution plane-VLS-grating monochromator

Published: May 2022

We propose a broadband single-element monochromator with a constant deviation angle and fixed slits for the wavelength range of 3–60 nm, which uses a grazing incidence plane varied line-space (VLS) grating with exponential dependence of line frequency across the aperture. Wavelength scanning is performed by translating the VLS grating along its surface. The deviation angle is constant, and the source, input, and output slits are stationary. With an exit slit (or CCD pixel size) of 6 µm, the practical resolving power

Published: May 2022

In this article we present a directly diode-pumped high-power Kerr-lens mode-locked Yb:CALGO bulk laser oscillator operating at 1-GHz repetition rate. We report on two laser configurations optimized for either highest average power or shortest pulse duration. In the first configuration optimized for high average power, the oscillator delivers up to 6.9 W of average power, which is the highest average power of any ultrafast laser oscillator operating at gigahertz repetition rate. The 93-fs pulses have a peak power of 64 kW, and the optical-to-optical efficiency amounts to 37%. In the second configuration optimized for short pulse duration, we demonstrate 48-fs pulses at 4.1 W of average power corresponding to a higher peak power of 74 kW with 21% optical-to-optical efficiency. This is the shortest pulse duration and the highest peak power demonstrated by any GHz-class Yb-based laser oscillator. The compact laser setup is directly pumped by a low-cost multimode fiber-coupled laser diode and has a high potential as an economical yet powerful source for various applications.
