Abstract
Background
Childhood obesity can affect physical as well as psychosocial wellbeing. Therefore, childhood obesity care aims to improve all dimensions of health related quality of life (HRQoL). HRQoL can be measured with the generic questionnaire PedsQL4.0 and the weight-specific IWQOL-Kids. In the Netherlands, HRQoL assessment is conducted by the coordinating professional (CP). The aim of this qualitative study was to examine how and when to implement the measurement and discussion of HRQoL using the PedsQL4.0 and IWQOL-Kids within the integrated care for children with obesity in the Netherlands. Semi-structured interviews were conducted with fourteen CPs, in which the following was discussed: a) familiarity and attributions with regard to the assessment of HRQoL; b) wishes and needs with regard to the usage of the questionnaires; c) its practical incorporation.

Results
Interviews revealed that most CPs gained insight into the HRQoL by talking with families. One CP used the PedsQL4.0, the remaining CPs were unfamiliar with the two questionnaires. Even though some barriers, for instance a lack of time, might hinder the implementation of the PedsQL4.0 and IWQOL-Kids, all participants think the usage of either one or both questionnaires would have additional value to the support and care for children with obesity. There was no consensus about the questionnaire of preference.

Conclusions
When the right preconditions are met, HRQoL questionnaires have the potential to support CPs in improving the care for children with obesity, tailored to each individual child.
Malignant giant solitary fibrous tumour of the mediastinum; masquerading Triton tumour
Authors: Beg Arshi , Parikh Jeenal , Janu Amit , Kaushal Rajiv Kumar 
Published: October 2021

Abstract
Background
Malignant Solitary fibrous tumour (SFT) is an uncommon mesenchymal tumour with aggressive clinical behaviour as compared to its benign counterpart. There are only a handful of reports of extra-pleural malignant SFT arising from the mediastinum.

Case presentation
A 68-year-old male, presented with a history of cough and breathlessness for 2 weeks. Computed tomography (CT) scan revealed a large 11.6 × 11.3x18cm anterior mediastinal mass with extension to right hemithorax. The patient underwent excision of the mass after a biopsy confirmation of mesenchymal tumour. Histological examination of resection specimen revealed a spindle cell tumour with hypo and hypercellular areas, arranged in fascicular, focal storiform and hemangio-pericytomatous vasculature pattern. Moderate to marked nuclear atypia, frequent mitosis and areas of necrosis were noted. On immunohistochemistry (IHC), the tumour cells were positive for CD34, Bcl2, MIC2 (dot-like) and focally for S100 and Desmin. Although, the possibility of a malignant peripheral nerve sheath tumour with heterologous rhadomyosarcomatous differentiation (Triton tumour) was considered, however IHC for STAT6 confirmed it to be a malignant SFT. The patient developed recurrence within 1 year after surgery and despite multi-modality treatment (Re-excision, Chemotherapy and Radiotherapy) succumbed within 14 months from point of presentation.

Conclusion
Malignant SFT is a rare aggressive tumour that should be considered as a differential diagnosis in the mediastinum and a broad panel of IHC markers including STAT6 may be required to confirm the diagnosis.

Published: October 2021

Abstract
Background
Airway anesthesia is pivotal for successful awake intubation provided either topically or by nerve blocks. The widespread use of ultrasonography allows anesthesiologists to evaluate complex and varied anatomy before needle insertion. This study aims to evaluate the effect of ultrasound-guided technique for the block of the internal branch of the superior laryngeal nerve in difficult airway patients in comparison to blind anatomical technique. Sixty patients aged 18–60 years, of either sex, with the American Society of Anesthesiologists’ physical status (ASA) I–II were divided into two groups 30 patients of each. Group (L): using anatomical landmark technique to bilateral block internal branch of the superior laryngeal nerve (ibSLN) with 1 mL 2% Lidocaine and group (U): using ultrasound technique to bilateral block the ibSLN with 1 mL 2% Lidocaine. Assessment of the excellence of airway anesthesia during intubation by using the 5 points grading scale, time for intubation, effects on hemodynamic variables, and evaluation of patient awareness of pain and discomfort during fiber-optic intubation using numerical rating scale were compared.

Results
The duration of tracheal intubation was shorter in the ultrasound group as compared to the anatomical group; also, patient comfort was significantly better in the ultrasound group besides the effect of tracheal intubation on hemodynamics which was significant with a higher peak value during intubation and post-intubation in the anatomical group compared to the ultrasound group.

Conclusions
This study concludes that an ultrasound-guided block of ibSLN used as a part of the preparation of the airway for awake fiber-optic intubation enhances the quality of airway anesthesia and patient tolerance during the procedure.

AbstractThe adsorption process of the industrialized dye Isolan Dark Blue 2SGL-01 (IDB) onto (Mg-Zn)/(Al-Fe)-(CO3)/Cl layered double hydroxides (LDHs) coded LDH21 and LDH22 and its calcined products CLDHs (CLDH21 and CLDH22), respectively, was investigated. The characterization of LDHs and CLDHs before and after loading with IDB by Fourier transform infrared, scanning electron microscope and surface area measurements showed a typical hydrotalcite structure and confirmed the loading of IDB. The adsorption parameters; initial pH, shaking time, adsorbent dose, initial concentration of IDB dye and temperature were studied. The optimum conditions for IDB adsorption were pH 4.3 and shaking time 3 h. A complete removal of IDB (> 99%) was achieved using a dosage of 2.0 g L− 1 CLDHs or LDH22, and 3.0 g L− 1 of LDH21. The adsorption processes were suggested to be best described by the pseudo-second order kinetics and Langmuir-type adsorption isotherm with monolayer capacities of 75, 91, 427 and 530 mg g− 1, onto LDH21, LDH22, CLDH21 and CLDH22, respectively. The loaded IDB was recovered from LDHs and CLDHs adsorbent using Na2CO3. CLDH22 showed best adsorption capacity of 530 mg g− 1. Its adsorption thermodynamic parameters ∆Gadsorption, ∆Hadsorption and ∆Sadsorption indicated that the adsorption processes were spontaneous and endothermic in nature. CLDH22 was successfully applied for the removal of IDB from simulated dyeing process with removal efficiency 97%.
Knowledge, attitudes and practices survey of cardiac rehabilitation among cardiologists and cardiac surgeons in Lebanon
Authors: Farah Rebecca , Groot Wim , Pavlova Milena 
Published: October 2021

Abstract
Background
Cardiovascular diseases (CVDs) are among the leading causes of morbidity and mortality worldwide. Over three quarters of the cardiovascular deaths take place in low and middle-income countries. Despite the benefits, Cardiac Rehabilitation (CR) is still not routinely and not universally available. Numerous studies have found that barriers to access to CR are correlated with providers, patients and environment characteristics. This first national survey on CR in Lebanon assesses the knowledge, attitudes and practices among physicians. In addition, the study identifies what the main barriers to access to CR are and provides suggestions for the implementation of CR in the country.

Results
The response rate was 41.5% (n = 83). Results show that the cardiologists have medium level of knowledge about CR and its multidisciplinary content. Physicians support the implementation of a comprehensive CR program in the country. 50% of the physicians recommended first to solve the financial issues before implementing a CR program. Supplementary learning about the benefits of CR is highly recommended to enroll more patients with CVD into CR. In addition, the lack of specialists in the field, lack of motivation for patients to enroll to CR and inconvenient location of the rehabilitation centers were identified as major barriers by the respondents.

Conclusions
The role of physicians in promoting patient enrolment should be optimized and exploited in the country. The access barriers identified can help to develop CR programs and to improve CR referral and enrolment rates. Funds from private parties and a budget from the government are needed to launch new CR programs in the country. Further research is needed to provide evidence on the CR benefits in Lebanon and to motivate policy-makers to place priority on the establishment of a comprehensive CR program in the country.
Studying the behavior of geopolymer concretes under repeated loadings
Authors: Al-Kerttani Osamah M. G. , Mutar Ammar 
Published: October 2021

AbstractThis article investigates utilization of polypropylene microfibers as reinforcement in geopolymer concrete to enhance the ductility characteristics since the geopolymer concrete is considered a brittle material. The polypropylene microfibers were added to geopolymer concrete at the fiber volume content of 0.5%, 1.0%, and 1.5%. In this article, a slump test and compressive strength were tested for geopolymer concretes to measure the effect of polypropylene microfibers on geopolymer concretes. Also, static flexural strength and dynamic loading were applied to find out the attitude of polypropylene fiber-reinforced geopolymer concrete and to measure both the deflection and number of load cycles until failure. While comparing the results with reference geopolymer concrete, all samples were tested at 28 days and, finally, a statistical test was carried out. The results concluded that the use of polypropylene microfibers improves the compressive strength and enhances the properties of polypropylene fiber-reinforced geopolymer concretes, increases the loading for the appearance of the first crack, and decreases the deflection of polypropylene fiber-reinforced geopolymer concretes compared with reference geopolymer concrete.

Published: October 2021

Background: Digital twin requires virtual reality mapping and optimization iteration between physical devices and virtual models. The mechanical movement data collection of physical equipment is essential for the implementation of accurate virtual and physical synchronization in a digital twin environment. However, the traditional approach relying on PLC (programmable logic control) fails to collect various mechanical motion state data. Additionally, few investigations have used machine visions for the virtual and physical synchronization of equipment. Thus, this paper presents a mechanical movement data acquisition method based on multilayer neural networks and machine vision. Methods: Firstly, various visual marks with different colors and shapes are designed for marking physical devices. Secondly, a recognition method based on the Hough transform and histogram feature is proposed to realize the recognition of shape and color features respectively. Then, the multilayer neural network model is introduced in the visual mark location. The neural network is trained by the dropout algorithm to realize the tracking and location of the visual mark. To test the proposed method, 1000 samples were selected. Results: The experiment results shows that when the size of the visual mark is larger than 6mm, the recognition success rate of the recognition algorithm can reach more than 95%. In the actual operation environment with multiple cameras, the identification points can be located more accurately. Moreover, the camera calibration process of binocular and multi-eye vision can be simplified by the multilayer neural networks. Conclusions: This study proposes an effective method in the collection of mechanical motion data of physical equipment in a digital twin environment. Further studies are needed to perceive posture and shape data of physical entities under the multi-camera redundant shooting.

Abstract. Abebe M. 2021. The ethnomedicinal plants used for human ailments at Mojana Wodera District, central Ethiopia. Biodiversitas 22: 4676-4686. An ethnobotanical study was carried out from March 2020 to February 2021 in selected sites of Mojana Wodera District to assess, identifying, and document medicinal plants to treat human ailments. Purposely and volunteer sampling techniques were applied to select 73 practitioners. Of those, 10 practitioners were key informants. Data was collected from informants using semi-structured interviews, focus group discussions, participant observation, and walk-in-the-word. The collected data were entered into an excel spreadsheet for statistical analysis. ANOVA and t-test were applied to compare the knowledge of the informants in different groups. ICF and FL values were calculated to identify the most common human ailments and heal the potential of medicinal plants. The result showed that a higher average (p< 0.05) was recorded for crucial informants, illiterate and higher aged group. Still, there was a significant difference between male and female informants (p=0.032) on knowledge of medicinal plants. A total of 45 medicinal plant species (41 genera and 27 families) were identified to treat 35 types of ailments. From this total, 15.6% were endemic for Ethiopia. Family Euphorbiaceae was dominant (11.1%) for this study. In the finding, the leaf was the most widely plant part which is used to prepare remedies (29.79%), followed by root (28.72%), and the most popular remedy preparation was pounding (31.18%). A higher ICF value (0.78) was recorded for dermatological category ailments, and the highest FL (94.12%) occurred for Laggera tomentosa, which was under the therapeutic category of the throat and respiratory.
Dissolved gas sensing using an anti-resonant hollow core optical fiber
Authors: Kapit Jason , Michel Anna P. M. 
Published: October 2021

Sensors that measure dissolved gases directly are needed for
environmental, industrial, and biomedical applications. Here we
present a hollow core fiber optic sensor capable of measuring
dissolved methane gas in liquids using only nanoliters of sample gas.
The sensor is based on an anti-resonant hollow core fiber combined
with a permeable capillary membrane inlet that extracts gas from the
liquid for analysis. Using a small capillary inlet for gas extraction
is only possible due to the small amount of sample gas needed for
analysis, and it presents new possibilities for dissolved gas analysis
in a simple, robust, and compact sensor configuration. We demonstrate
the sensing technique using wavelength modulation spectroscopy and
measure methane dissolved in water with a

. We temporally characterize the pulses to show that they are 42 fs in duration, much shorter than the pump pulse. In the non-collinear setup, the angle between the pump and seed selects the amplified wavelength, where we find certain angles amplify both the visible and near-infrared simultaneously. We find that near the maximum pumping intensities, higher-order nonlinearities may play a role in the amplification process.

Prevalence and health correlates of Onine Fatigue: A cross-sectional study on the Italian academic community during the COVID-19 pandemic
Authors: Bonanomi Andrea , Facchin Federica , Barello Serena , Villani Daniela 
Published: October 2021

BackgroundDuring the COVID-19 pandemic, many people had to shift their social and work life online. A few researchers and journalists described a new form of fatigue associated with a massive use of technology, including videoconferencing platforms. In this study, this type of fatigue was referred to as Online Fatigue. A new tool (the Online Fatigue Scale) was developed, and its psychometric properties were evaluated. This tool was used to assess Online Fatigue among Italian academics and to examine its associations with psychological and physical health.MethodsAn online survey was conducted in December 2020 on a sample of Italian academics. Besides the Online Fatigue Scale (11 items) used to assess Online Fatigue, the survey was composed of questionnaires (including validated measures) focused on sociodemographic and job-related information, technostress creators, health status, psychological well-being, and COVID-related perceived distress. The psychometric properties of the Online Fatigue Scale were evaluated, and statistical analyses were conducted to examine the associations between Online Fatigue and all the other variables.ResultsParticipants were 307 academics aged 24–70 years old (mean age = 40.7; SD = 10.1). The Online Fatigue Scale showed good psychometric properties. Two subscales were identified: Off-Balance Fatigue and Virtual Relations Fatigue. High levels of Off-Balance Fatigue were associated with a greater use of technology, female gender, and presence of minor children. Participants with high scores on both subscales reported a greater frequency of psychosomatic symptoms, unhealthy habits, poorer psychological well-being, and greater Covid-related perceived distress.ConclusionsThe Online Fatigue Scale can be considered a reliable tool to assess Online Fatigue, which was significantly detected in our sample of Italian academics, along with its negative effects on physical and psychological health. Being a woman and having young children represent important risk factors. Universities should promote the separation between work and private life by encouraging self-care activities.

Published: October 2021

BackgroundChronic kidney disease (CKD) is an emerging public health issue globally. The prevalence estimates on CKD in South Asia are however limited. This study aimed to examine the prevalence of CKD among the general and high-risk population in South Asia.MethodsWe conducted a systematic review and meta-analysis of population-level prevalence studies in South Asia (Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, India, Pakistan, and Sri Lanka). Three databases namely PubMed, Scopus and Web of Science were systematically searched for published reports of kidney disease in South Asia up to 28 October 2020. A random-effect model for computing the pooled prevalence was used.ResultsOf the 8749 identified studies, a total of 24 studies were included in the review. The pooled prevalence of CKD among the general population was 14% (95% CI 11–18%), and 15% (95% CI 11–20%) among adult males and 13% (95% CI 10–17%) in adult females. The prevalence of CKD was 27% (95% CI 20–35%) in adults with hypertension, 31% (95% CI 22–41%) in adults with diabetes and 14% (95% CI 10–19%) in adults who were overweight/obese. We found substantial heterogeneity across the included studies in the pooled estimates for CKD prevalence in both general and high-risk populations. The prevalence of CKD of unknown origin in the endemic population was 8% (95% CI 3–16%).ConclusionOur study reaffirms the previous reports that CKD represents a serious public health challenge in South Asia, with the disease prevalent among 1 in 7 adults in South Asian countries.

Published: October 2021

Background
Anxiety, nausea and vomiting are common side effects suffered by paediatric patients receiving chemotherapy. Emerging evidence supports the efficacy of immersive virtual reality (IVR) on improving anxiety and distress symptoms including nausea and vomiting among this vulnerable group. This trial aims to assess the feasibility and acceptability of IVR for preventing and managing anxiety, nausea and vomiting among paediatric cancer patients receiving their first chemotherapy.

Method and analysis
An exploratory trial supplemented by qualitative methods will be conducted. We will recruit 20 paediatric patients who are aged between 6 and 12 years, chemotherapy naïve, scheduled to receive their first intravenous chemotherapy and able to understand Chinese. Participants will be randomly allocated to intervention or control groups. The intervention group will receive the IVR intervention for three sessions as follows: 4 hours before chemotherapy, 5 minutes before and during their first course chemotherapy and 5 minutes before and during their second course chemotherapy. The control group will receive standard care only. Main outcome measures included (1) key parameters for the design of a definitive trial (i.e. screening, eligibility, consent and withdrawal rates); (2) anxiety, anticipatory and acute chemotherapy-induced nausea and vomiting for collection of preliminary data; (3) feasibility and acceptability of the intervention. Semi-structured interviews will be conducted with patients, parents and oncology nurses. Generalized estimating equations model will be used to compare each of the outcome measures across the time points between the two groups. Qualitative data will be analysed by conventional content analysis.

Expected results
The results of this exploratory trial will inform the design and conduct of future definitive trial.
