BackgroundAlthough the Thai government has introduced policies to promote health of migrants, it is still the case that urban refugees and asylum seekers (URAS) seem to be neglected. This study aimed to explore the degree of healthcare access through the perspective of unmet need in URASs, relative to the Thai population.MethodsA cross-sectional survey, using a self-reporting questionnaire adapted from the Thai Health and Welfare Survey (HWS), was performed in late 2019, with 181 URASs attending the survey. The samples were randomly selected from the roster of the Bangkok Refugee Center. The data of the URAS survey were combined with data of the Thai population (n=2,941) from the HWS. Unmet need for health services was defined as the status of when a respondent needed healthcare in the past twelve months but failed to receive it. Bivariate analysis was conducted to explore the demographic and unmet need difference between URASs and Thais. Multivariable logistic regression and mixed-effects (ME) model were performed to determine factors associated with unmet need. ResultsOverall, URASs were of lower age, less educated and living in more economically deprived households, compared with Thais. About 98% of URASs were uninsured by any of the existing health insurance schemes. The prevalence of unmet need among URASs was significantly higher than Thais in both outpatient (OP) and inpatient (IP) services (54.1% versus 2.1% and 28.0% versus 2.1%, respectively). Being uninsured demonstrated the greatest degree of association with unmet need, especially for OP care. The association between insurance status and unmet need was more pronounced in ME model, relative to multivariable logistic regression. URASs migrating from Arab nations suffered from unmet need to a greater extent, compared with those originating from non-Arab nations. ConclusionThe prevalence of unmet need in URASs was drastically high, relative to the prevalence in Thais. Factors suggesting a positive relationship with unmet need included advanced age, lower education achievement, and, most evidently, being unsinured. Policy makers should consider a policy option to enrol URASs in the nationwide public insurance scheme to create health security for the entire Thai society.
Limited access to family-based addiction prevention services for socio-economically deprived families in Switzerland: a grounded theory study
Authors: Pfister Andreas , Koschmieder Nikola , Wyss Sabrina
Published: September 2020

Background: Families living in poor socio-economic circumstances, already confronted with social and health inequalities, are often not reached by family-based addiction prevention services. Besides quantitative models and health literacy approaches, qualitative research is lacking that could shed light on the exact circumstances and processes that lead to hindered addiction prevention service uptake by these families. Drawing on the concept of candidacy, we therefore reconstructed how socio-economically deprived parents and their (pre)adolescent children in the German-speaking part of Switzerland (non-)identified their candidacy for family-based addiction prevention services.Methods: Following grounded theory, we collected and analysed data in an iterative-cyclical manner using theoretical sampling and theoretical coding techniques. Sixteen families with children aged 10–14 years were interviewed in depth (parent/s and child separately). All but one family lived below the at-risk-of-poverty threshold.Results: Socio-economically deprived families’ modes of recognizing and handling problems in everyday life were found to be core phenomena that structure the process towards (non)identification of candidacy for family-based addiction prevention services. Four modes anchored within socio-demographic resources were found: Families with mode A perceived their current life situation as existentially threatening and focused daily coping on the main pressing problem. Others (mode B) perceived prevalent multiple problems as normal (now); problems were normalized, often not recognized as such. In mode C families, problems were pragmatically recognized at a low threshold and pragmatically dealt with, mostly within the family. In mode D families, problems were constantly produced and dealt with early by the worried and anxious parents monitoring their child. From modes D to A, vulnerability increased concerning non-identification of candidacy for family-based addiction prevention services. Further, thematic relevance of addiction prevention, past experience with offers, integration in systems of assistance, strategies to protect the family, and families’ search for information influenced whether identification of candidacy took place.Conclusions: Socio-economically deprived families differ in modes of problem construction and handling in everyday life; this differently opens up or closes routes to family-based addiction prevention. Addiction prevention practice should build on a bundle of diverse strategies for outreach to these families, stressing especially interventions on the structural and environmental level.

Background: This study explored the relationships between the low-/high-density lipoprotein cholesterol ratio (LDL-C/HDL-C) and other clinical indicators and ischaemic stroke (IS) in patients with non-valvular atrial fibrillation (NVAF) in Xinjiang. The findings could provide a theoretical and therapeutic basis for NVAF patients.Methods: NVAF patients who were admitted to 10 medical centres across Xinjiang were divided into stroke (798 patients) and control (2671 patients) groups according to the occurrence of first acute IS. Univariate and multivariate logistic regression analysis were used to examine the independent risk factors for IS in NVAF patients. Factor analysis and principal component regression analysis were used to analyse the main factors influencing IS. Receiver operating characteristic (ROC) curve analysis was used to evaluate the discriminatory ability of LDL-C/HDL-C for predicting the occurrence of IS.Results: The stroke group had an average age of 71.64 ± 9.96 years and included 305 females (38.22%). The control group had a mean age of 67.30 ± 12.01 years and included 825 females (30.89%). Multivariate logistic regression showed that the risk of IS in the highest LDL-C/HDL-C quartile ( ≥2.73) was 16.23-fold that of the lowest quartile ( < 1.22); IS risk was 2.27-fold higher in obese patients than in normal-weight subjects; IS risk was 3.15-fold higher in smoking patients than in non-smoking patients. The area under the ROC curve of LDL-C/HDL-C was 0.76, the optimal critical value was 2.33, the sensitivity was 63.53%, and the specificity was 76.34%. Principal component regression analysis showed that LDL-C/HDL-C, age, smoking, drinking, LDL-C and hypertension were risk factors for IS in NVAF patients.Conclusions: LDL-C/HDL-C >1.22, smoking, BMI ≥24 kg/m2 and CHA2DS2-VASc score were independent risk factors for IS in NVAF patients; LDL-C/HDL-C was the main risk factor.

Published: September 2020

Background: Synapse and synapse associated proteins (SAPs) play critical roles in various neurodegeneration diseases and brain tumors. However, in lower-grade gliomas (LGG), SAPs have not been explored systematically. Herein, we are going to explore SAPs expression profile and its clinicopathological significance in LGG which can offer new insights to glioma therapy. Method: In this study, we used five sources including, Venkatesh, Shen, Colón, Jüttner R, Gene Ontology (GO) project to integrate a list of SAPs that covered 231 proteins with synaptogenesis activity and post synapse formation. The LGG RNA-seq data were downloaded from gene expression omnibus (GEO) database, The Cancer Genome Atlas (TCGA), and Chinese Glioma Genome Atlas (CGGA). The differentially expressed SAPs were filtered out and constructed PPI to search for key modules and SAPs. Then, using Kaplan–Meier survival analysis, least absolute shrinkage and selection operator (LASSO), and multicox regression analysis, the prognostic significance of these key SAPs was evaluated. CGGA database, Human Protein Altas (HPA) and quantitative real-time PCR were used to verify our findings. Result: Data from function enrichment analysis revealed functions of differentially expressed SAPs in synapse organization and glutamatergic receptor pathway in LGGs. Survival analysis revealed four SAPs, GRIK2, GABRD, GRID2, ARC that were correlate with the prognosis of LGG patients and used to construct the prognostic models. Among them, the expression of GABRD was lower in glioma tissue than normal brain tissue, but higher in seizure LGG patients than non-seizure patients. The four-SAPs signature was revealed as an independent prognostic factor in gliomas.Conclusion: Our study presented a novel strategy to assess the prognostic risks of LGGs, based on the expression of SAPs. Also, we revealed that several SAPs upregulated in patients with seizures, indicating that they are linked to the pathogenesis of seizures in glioma patients.
Development of 96-microwell Plate Assay with Fluorescence Reader and HPLC Method with Fluorescence Detection for High-throughput Analysis of Linifanib in its Bulk and Dosage Forms
Authors: Khalil Nasr Y. , Darwish Ibrahim A. , Alanazi Mamdouh , Hamidaddin Mohammed A.
Published: September 2020

Background:

Linifanib (LFB) is a tyrosine kinase inhibitor with antineoplastic activity.
The existing methods for the analysis of LFB in bulk and dosage forms do not meet the requirements
of quality control (QC) analysis.

Objective:

The present study was devoted to the development of two methods with high throughputs
for determination of LFB. These methods are 96-microwell plate assay with microplate fluorescence
reader (MWP-FR) and high-performance liquid chromatography with fluorescence detection
(HPLC-FD).

Methods:

The MWP-FR assay was carried out in white opaque 96-well assay plates and the native
fluorescence signals of LFB were measured at 360 nm for excitation and 500 nm for emission. In
the HPLC-FD, the chromatographic separation of LFB and quinine sulphate (QS) as internal standard
(IS) was performed on µ-Bondapack CN HPLC column using a mobile phase consisting of
acetonitrile:water (60:40, v/v) pumped at a flow rate of 1 ml/min in an isocratic mode. The fluorescence
detector was set at 350 nm for excitation and 454 nm for emission.

Results:

The linear ranges of the MWP-FR and HPLC-FD were 1-12 µg/well and 10-500 ng/ml, respectively.
The limits of detection were 0.85 µg/well and 8.24 ng/ml for MWP-FR and HPLC-FD,
respectively. Both MWP-FR and HPLC-FL methods were successfully applied for the determination
of LFB in both bulk and tablets.

Conclusion:

Both methods have high analytical throughputs, they are suitable for use in QC laboratories
for analysis of large numbers of LFB samples, and are environmentally friendly as they consume
low volumes of chemicals and solvents.

Upcycling Culinary Organic Waste: Production of Plant Particles from Potato and Carrot Peels to Improve Antioxidative Capacity
Authors: Yassin Dalia A. , Nasim Muhammad Jawad , Abraham Abraham M. , Keck Cornelia M. , Jacob Claus
Published: September 2020

Background:

Vegetables and fruits are consumed in considerable amounts worldwide
producing huge quantities of organic leftovers comprising primarily of peels. Peels of potatoes (PP) and
carrots (CP), for instance, are often considered as waste, albeit they still represent a rich source of
interesting phytochemicals. Traditional waste management of such materials, usually vermicomposting,
therefore represents a low-value approach and also a considerable burden to the environment.

Objective:

Aiming to convert some of this waste into raw materials for further applications,
methods were explored to prepare suspensions of PP and CP. Antioxidant activities of these
suspensions were compared to bulk-suspensions and the corresponding ethanolic extracts in
anticipation of possible applications in Nutrition and Cosmetics.

Methods:

The peels of potatoes and carrots were subjected to high- speed stirring (HSS) and highpressure
homogenization (HPH) to produce suspensions which were characterized for size
distribution by Laser Diffraction (LD), Photon Correlation Spectroscopy (PCS), and light
microscopy (LM). Ethanolic extracts of peels were also produced. Samples were evaluated for
antioxidant activity employing 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay.

Results:

HPH produced suspensions of peels comprising particles with diameters in the range of
268 - 335 nm for PP and 654 - 1,560 nm for CP. These suspensions exhibited a significantly
stronger antioxidant activity compared to the bulk-suspensions. Moreover, the suspension of PP
(1% w/w) exhibited comparable antioxidant activity to the ethanolic extract (1% w/w) whilst the
CP suspension (1% w/w) exhibited lower activity compared to the ethanolic extract.

Conclusion:

Production of suspensions of vegetable peels may unlock some biological potential
which could be optimised for applications in Nutrition, Agriculture, Medicine and Cosmetics.

This research aimed to study the acceptance level and visual test of weldments in a pressure vessel in the national skills competition of vocational students in 2019. The approach of this research is quantitative-descriptive. Data were collected using checklists of quality assessment of the weld results. The tests for quality were pressure test and visual test. This research was conducted at the national skill competition in 2019 at Jogja Expo Center. The sample of this study was 32 welders. The results revealed that the acceptance level was considerably low, in which only 1 out of 32 participants passed the pressure test. Results from the visual quality were also low due to lack of understanding and knowledge in determining the requirements of pressure vessel welding, especially for the welding code and assembly drawing symbols. Participants were also unable to choose the right welding current, lacks theoretical knowledge of metals characteristics and welding processes types, and low awareness of OSH equipment.  Most participants were also lacking in practical knowledge on how to avoid welding defects in the pressure vessel weldments.Penelitian ini bertujuan mengetahui tingkat kelolosan hasil pengelasan pressure vessel  pada lomba kompetensi siswa SMK tingkat nasional tahun 2019. Penelitian ini merupakan penelitian deskriptif kuantitatif. Metode pengumpulan data dalam penelitian ini menggunakan check list penilaian kualitas hasil pengelasan siswa dengan uji tingkat kelolosan kebocoran dan uji visual. Penelitian ini dilaksanakan di Jogja expo center (JEC) sebagai tempat LKSN. Sampel dari penelitian ini adalah 32 siswa, analisis data dilakukan dengan analisis deskriptif. Hasil penelitian menunjukkan bahwa: tingkat kelolosan uji pressure vessel masih sangat rendah dimana dari 32 peserta yang lolos uji pressure hanya 1 orang, kualitas hasil visual pengelasan pressure vessel masih rendah hal tersebut disebabkan kurangnya pemahaman dan pengetahuan tentang menentukan persyaratan pengelasan pressure vessel khususnya dalam mengetahui kode pengelasan dan simbol gambar kerja asembly, mengetahui jenis bahan logam, mengetahui jenis proses pengelasan SMAW, GMAW, GTAW dan FCAW serta mengetahui fungsi alat keselamatan dan kesehatan kerja, serta pemahaman terhadap cara untuk menghindari cacat-cacat las pada hasil pengelasan pressure vessel.

Detecting stress from imaging photoplethysmography using high frame rate video and a yellow-green filter: A pilot study
Authors: Aquilina Peter Vincent , Booth David , Pincombe Brandon , Hanly Gary , Meaney Kym , Darvishi Sam
Published: September 2020

We investigate the use of a yellow-green filter to increase the signal-to-noise ratio (snr) in imaging photoplethysmography (iPPG) and test if high frame rate (HFR) video improves the accuracy of the derived heart rate variability (HRV). This pilot study is associated with a broader program to use iPPG to detect and monitor stress levels using HRV. To improve the snr of the iPPG signal, we employ two HFR colour video cameras of which one was fitted with a yellow-green filter (corresponding to the haemoglobin absorption peak within the visible spectrum). To our knowledge, the benefit of a yellow-green filter has never been explored. The predominant influence on HRV comes from the autonomic nervous system (ANS), which connects directly to the heart and cues the human body to relax or to stress. The linkage of HRV to the ANS makes HRV a proxy for stress levels. The HRV is derived from the iPPG signal by first using a cubic spline interpolation for more precise peak detection, and then calculating the inter-beat intervals from the peak-to-peak time differences. Instead of interpolating the signal, we hypothesise that a more accurate HRV measurement can be obtained using a HFR video camera, in our case at 200 frames per second.

Topics, Trends, and Sentiments of Tweets About the COVID-19 Pandemic: Temporal Infoveillance Study
Authors: Chandrasekaran Ranganathan , Mehta Vikalp , Valkunde Tejali , Moustakas Evangelos

Background

With restrictions on movement and stay-at-home orders in place due to the COVID-19 pandemic, social media platforms such as Twitter have become an outlet for users to express their concerns, opinions, and feelings about the pandemic. Individuals, health agencies, and governments are using Twitter to communicate about COVID-19.

Objective

The aims of this study were to examine key themes and topics of English-language COVID-19–related tweets posted by individuals and to explore the trends and variations in how the COVID-19–related tweets, key topics, and associated sentiments changed over a period of time from before to after the disease was declared a pandemic.

Methods

Building on the emergent stream of studies examining COVID-19–related tweets in English, we performed a temporal assessment covering the time period from January 1 to May 9, 2020, and examined variations in tweet topics and sentiment scores to uncover key trends. Combining data from two publicly available COVID-19 tweet data sets with those obtained in our own search, we compiled a data set of 13.9 million English-language COVID-19–related tweets posted by individuals. We use guided latent Dirichlet allocation (LDA) to infer themes and topics underlying the tweets, and we used VADER (Valence Aware Dictionary and sEntiment Reasoner) sentiment analysis to compute sentiment scores and examine weekly trends for 17 weeks.

Results

Topic modeling yielded 26 topics, which were grouped into 10 broader themes underlying the COVID-19–related tweets. Of the 13,937,906 examined tweets, 2,858,316 (20.51%) were about the impact of COVID-19 on the economy and markets, followed by spread and growth in cases (2,154,065, 15.45%), treatment and recovery (1,831,339, 13.14%), impact on the health care sector (1,588,499, 11.40%), and governments response (1,559,591, 11.19%). Average compound sentiment scores were found to be negative throughout the examined time period for the topics of spread and growth of cases, symptoms, racism, source of the outbreak, and political impact of COVID-19. In contrast, we saw a reversal of sentiments from negative to positive for prevention, impact on the economy and markets, government response, impact on the health care industry, and treatment and recovery.

Conclusions

Identification of dominant themes, topics, sentiments, and changing trends in tweets about the COVID-19 pandemic can help governments, health care agencies, and policy makers frame appropriate responses to prevent and control the spread of the pandemic.

BACKGROUND

Rapid and accurate diagnosis of chronic obstructive pulmonary disease (COPD) is problematic in acute care settings, particularly in the presence of infective comorbidities.

OBJECTIVE

The aim of this study was to develop a rapid smartphone-based algorithm for the detection of COPD in the presence or absence of acute respiratory infection and evaluate diagnostic accuracy on an independent validation set.

METHODS

Participants aged 40 to 75 years with or without symptoms of respiratory disease who had no chronic respiratory condition apart from COPD, chronic bronchitis, or emphysema were recruited into the study. The algorithm analyzed 5 cough sounds and 4 patient-reported clinical symptoms, providing a diagnosis in less than 1 minute. Clinical diagnoses were determined by a specialist physician using all available case notes, including spirometry where available.

RESULTS

The algorithm demonstrated high positive percent agreement (PPA) and negative percent agreement (NPA) with clinical diagnosis for COPD in the total cohort (N=252; PPA=93.8%, NPA=77.0%, area under the curve [AUC]=0.95), in participants with pneumonia or infective exacerbations of COPD (n=117; PPA=86.7%, NPA=80.5%, AUC=0.93), and in participants without an infective comorbidity (n=135; PPA=100.0%, NPA=74.0%, AUC=0.97). In those who had their COPD confirmed by spirometry (n=229), PPA was 100.0% and NPA was 77.0%, with an AUC of 0.97.

CONCLUSIONS

The algorithm demonstrated high agreement with clinical diagnosis and rapidly detected COPD in participants presenting with or without other infective lung illnesses. The algorithm can be installed on a smartphone to provide bedside diagnosis of COPD in acute care settings, inform treatment regimens, and identify those at increased risk of mortality due to seasonal or other respiratory ailments.

Published: September 2020

Se presenta un resumen de los factores que afectan de manera significativa a las propiedades catalíticas de los óxidos de metales de transición. Entre estos factores podemos mencionar el tamaño de partícula, su forma, su composición química, la interacción metal-soporte o la interacción catalizador-reactivo. Recientes investigaciones han demostrado que es posible controlar algunos de estos factores mediante una síntesis bien planeada y ejecutada, una caracterización profunda, y estudios teóricos de los catalizadores, que permitan conocer las estructuras electrónicas y geométricas del catalizador (como átomos simples, nanoaglomerados o nanopartículas) y correlacionarlas con su comportamiento en diferentes reacciones.
