RESUMO
Introduction: The recognition of religion's significance in mental health has led to several scientific advances in diagnosis or treatment. In contrast, Vietnam is a multi-religious Southeast Asian country with a large number of believers, but there is almost no research addressing the impact of religiosity among Vietnamese believers on mental health concerns such as depression, happiness, and gratitude. Participants and Methods: Our cross-sectional study was focused on Vietnamese believers (N = 374), surveyed directly at different religious facilities in Vietnam. The present study was evaluated utilizing the partial least squares-structural equation modeling (PLS-SEM) methodology. Results: The primary findings of the study indicate that (i) age was found to positively moderate the association between intrinsic religiosity and gratitude (ß = 0.191, 95% CI [0.116, 0.277], p < 0.001); (ii) Intrinsic religiosity has a positive influence on depression-happiness scale (ß = 0.276, 95% CI [0.168, 0.373], p < 0.001) and gratitude (ß = 0.337, 95% CI [0.205, 0.466], p < 0.001); Moreover, (iii) gratitude has a positive influence on depression-happiness scale (ß = 0.381, 95% CI [0.280, 0.491], p < 0.001); Finally, (iv) the study revealed that gratitude mediates the relationship between intrinsic religiosity and depression-happiness scale (ß = 0.128, 95% CI [0.071, 0.197], p < 0.001). Discussion: The findings of this study suggest that gratitude could potentially play a significant role in comprehending the association between religiosity and the levels of depression and happiness experienced by religious individuals in Vietnam.
RESUMO
There is limited information regarding the influence of mangrove growth on the morphological evolution of intertidal mudflats. In this study, Tan Phu Dong district, Tien Giang Province, Vietnam, was selected for investigating how mangrove growth influenced the morphological evolution of an intertidal mudflat. The authors analyzed a series of satellite images (from 1995 and 2022), calculated the enhanced vegetation index (EVI), and documented field visits and observations in pursuit of the objective of the study. The findings revealed that fine-grained sediment accumulated as unconsolidated substratum (US) in the first step of the morphological evolution of the intertidal mudflat, with sediment accumulation of 910 ha in 1995. The US provided favorable conditions for mangroves to grow, while mangrove growth helped compact the US into a compact substratum (CS) in addition to promoting continuous sediment accumulation, increased the vegetation cover of the island, and elevated the substrate density of the remaining areas. As a result, the US and CS decreased steadily between 1995 and 2020, from 910 ha in 1995 to 401 ha in 2020 and from 433 ha in 2005 to 111 ha in 2020, respectively. Meanwhile, the low-vegetation area (LVA), medium-vegetation area (MVA), and high vegetation area (HVA) gradually increased between 1995 and 2015, from 0 ha in 1995 to 104 ha in 2015, from 0 ha in 1995 to 96 ha in 2015, and from 0 ha in 1995 to 114 ha in 2015, respectively. However, the LVA decreased slightly between 2015 and 2020 due to significant sand accumulation, which significantly killed the mangrove trees. In contrast, the MVA and HVA steadily increased between 2015 and 2020, from 96 ha in 2015 to 116 ha in 2020 and from 114 ha in 2015 to 221 ha in 2020, respectively. In 2022, there was a steady increase in HVA (298 ha in 2022), although the date of the 2022 satellite retrieval was 28 January 2022. This study recommends that the technical design of the existing coastal protection works should be revised or adapted to take account of sediment accumulation as the first step in the morphological evolution of the examined intertidal mudflat, rather than mangrove growth.
RESUMO
BACKGROUND: The proportion of people with hypertension is increasing, and those affected are relatively younger. Worldwide, it is estimated that people with high blood pressure are more than 1.5 billion people. In Vietnam, from 2002 to 2008, according to a national survey on hypertension and its risk factors within the prevention and control of cardiovascular disease program, the prevalence of hypertension was 25.1%. This is alarming because high blood pressure can cause serious complications, including death. OBJECTIVE: The study aimed to explore the blood pressure characteristics and hypertension prevalence in adults in a northern delta province of Vietnam, and describe some risk factors in hypertensive subjects screened through the program. METHODS: This was a cross-sectional study collecting data from people aged 18 years or older in 10 cantons and the city of Nam Dinh from July 15th to July 31st, 2020. Using semi-automatic OMRON sphygmomanometers, sitting blood pressure was measured three times according to standardized methods specified by the Ministry of Health and two National Vascular Societies. RESULTS: Blood pressure screening of 183,632 adults included 84,438 males, which accounted for 45.98%, with an average age of 60.36 ± 13.18 years. The estimated prevalence of hypertension was 27.20% (95% CI: 27.00% - 27.41%). The older the age, the higher the rate of hypertension in both sexes; the prevalence of hypertension over 65 years was 45.36%. Hypertension grade 1 accounted for 17.14%, followed by hypertension at grade 2 at 6.69%, and grade 3 at 1.15%; notably, the percentage of prehypertension accounted for 49.64%. The percentage of treated hypertension in Nam Dinh province was 56.85%, but the percentage of uncontrolled hypertension was 85.63%. CONCLUSION: The prevalence of hypertension in Nam Dinh province was relatively high (27.20%), although the number of treated patients was also high (56.85%); moreover, the proportion of uncontrolled hypertension remained extremely high (85.63%). Local campaigns and suitable interventions are required to detect hypertension in the early stages and increase awareness for treatment in the population.
RESUMO
Understanding the evolution of antibiotic resistance is important for combating drug-resistant bacteria. In this work, we investigated the adaptive response of Pseudomonas aeruginosa to ciprofloxacin. Ciprofloxacin-susceptible P. aeruginosa ATCC 9027, CIP-E1 (P. aeruginosa ATCC 9027 exposed to ciprofloxacin for 14 days) and CIP-E2 (CIP-E1 cultured in antibiotic-free broth for 10 days) were compared. Phenotypic responses including cell morphology, antibiotic susceptibility, and production of pyoverdine, pyocyanin and rhamnolipid were assessed. Proteomic responses were evaluated using comparative iTRAQ labelling LC-MS/MS to identify differentially expressed proteins (DEPs). Expression of associated genes coding for notable DEPs and their related regulatory genes were checked using quantitative reverse transcriptase PCR. CIP-E1 displayed a heterogeneous morphology, featuring both filamentous cells and cells with reduced length and width. By contrast, although filaments were not present, CIP-E2 still exhibited size reduction. Considering the MIC values, ciprofloxacin-exposed strains developed resistance to fluoroquinolone antibiotics but maintained susceptibility to other antibiotic classes, except for carbapenems. Pyoverdine and pyocyanin production showed insignificant decreases, whereas there was a significant decrease in rhamnolipid production. A total of 1039 proteins were identified, of which approximately 25â% were DEPs. In general, there were more downregulated proteins than upregulated proteins. Noted changes included decreased OprD and PilP, and increased MexEF-OprN, MvaT and Vfr, as well as proteins of ribosome machinery and metabolism clusters. Gene expression analysis confirmed the proteomic data and indicated the downregulation of rpoB and rpoS. In summary, the response to CIP involved approximately a quarter of the proteome, primarily associated with ribosome machinery and metabolic processes. Potential targets for bacterial interference encompassed outer membrane proteins and global regulators, such as MvaT.

Coulomb explosion imaging (CEI) with x-ray free electron lasers has recently been shown to be a powerful method for obtaining detailed structural information of gas-phase planar ring molecules [R. Boll et al., X-ray multiphoton-induced Coulomb explosion images complex single molecules, Nat. Phys. 18, 423 (2022).NPAHAX1745-247310.1038/s41567-022-01507-0]. In this Letter, we investigate the potential of CEI driven by a tabletop laser and extend this approach to differentiating three-dimensional structures. We study the static CEI patterns of planar and nonplanar organic molecules that resemble the structures of typical products formed in ring-opening reactions. Our results reveal that each molecule exhibits a well-localized and distinctive pattern in three-dimensional fragment-ion momentum space. We find that these patterns yield direct information about the molecular structures and can be qualitatively reproduced using a classical Coulomb explosion simulation. Our findings suggest that laser-induced CEI can serve as a robust method for differentiating molecular structures of organic ring and chain molecules. As such, it holds great promise as a method for following ultrafast structural changes, e.g., during ring-opening reactions, by tracking the motion of individual atoms in pump-probe experiments.
RESUMO
Congenital diaphragmatic hernia (CDH) can be diagnosed prenatally and its severity assessed by fetal imaging. The prognosis of a fetus with CDH is based on whether or not the hernia is isolated, the measurement of lung volume on ultrasound and MRI, and the position of the liver. The birth of a child with CDH should take place in a center adapted to the care of such children, and in accordance with the recommendations defined by the French National Diagnosis and Care Protocol. It has recently been demonstrated that for moderate and severe forms of CDH, tracheal occlusion using a balloon placed in utero by fetoscopy (FETO) increases survival until discharge from the neonatal unit, but at the cost of an increased risk of prematurity. At the same time, advances in neonatal resuscitation and the standardization of follow-up of these children within the framework of the "Centre de référence maladies rares: hernie de coupole diaphragmatique" have improved the prognosis of these children and young adults.
RESUMO
This study was focused on one particular case of hot-melt coating with trilaurin - a solid medium-chain monoacid triglyceride. The challenge of using trilaurin as coating agent in melting-based processes is linked to its relatively low melting profile: 15.6 °C (Tm,α), 35.1 °C ( [Formula: see text] ) and 45.7 °C (Tm,ß). From a process perspective, the only possibility to generate products coated with formulations composed of trilaurin is by setting thermal operational conditions above Tm,α. From a material perspective, this processing possibility depends principally on trilaurin crystallisation which was investigated via a set of analytical techniques including turbidimetry, calorimetry, hot-melt goniometry, and polarised light microscopy. A highly soluble drug model substrate (sodium chloride crystals) was coated with three selected trilaurin-based formulations: (i) trilaurin, (ii) trilaurin plus talc, and (iii) trilaurin plus vitamin E TPGS and talc. Coated salt crystals were then analysed to investigate processing performance, coating quality, stability and release properties under digestion effect. The results show that firstly, talc addition promotes nucleation and crystal growth and, as a consequence, it facilitates the manufacture of trilaurin-based formulations. Secondly, the formulation of a solid triglyceride and a hydrophilic surfactant could potentially cause release instability, but formula (iii) was found to be stabilised by a mechanism whereby trilaurin crystallization enhanced in the presence of talc immobilised vitamin E TPGS in its crystal lattice. Thirdly, talc addition did not significantly influence trilaurin digestion which endows products with an immediate release in lipolytic conditions instead of an extended liberation in pure water. Nor did the addition of one or two additives alter the extent of trilaurin digestion under the conditions studied. These important findings relate to product manufacturability, stability, and release properties. A good understanding of material properties (e.g. crystallisation, polymorphism, digestibility) is essential for melt-processing, lipid coating stabilising and modulation of release profile of solid lipid-coated product, as demonstrated in this case study with trilaurin.

In Vietnam, each primary care community health center (CHC) consists of a multi-professional team with six disciplines, including a physician, assistant physician, nurse, pharmacist, midwife, and Vietnamese traditional physician, who are able to meet the majority of patient's needs at the primary care level. How they collaborate, especially in chronic disease management (CDM), is still limited described in the literature. This study aims to gain insight into the perceptions and the experiences of primary health care providers (PHCPs) toward interprofessional collaboration (IPC) in CDM in CHCs in (Hue) Vietnam. A qualitative study of descriptive phenomenology was performed using two focus groups and 15 semi-structured interviews with PHCPs from six professions relevant to CDM in CHCs. The data were analyzed using NVivo 12.0 with a thematic analysis method by a multiprofessional research team. From the analysis, the data were classified into three main themes: "lack of collaborative practice," "knowledge," and "facilitators and barriers to IPC." This study provided evidence of the awareness that actual collaboration in daily care is fragmentarily organized and that PHCPs try to finish their tasks within their profession. PHCPs work multiprofessionally and lack shared decision-making in patient-centered care. There is a need to develop an interprofessional education program and training to address these deficiencies in the Vietnamese context to improve interprofessional collaboration in health care.

Introduction: Mediport use as a clinical option for the administration of chimeric antigen receptor T cell (CAR T cell) therapy in patients with B-cell malignancies has yet to be standardized. Concern for mediport dislodgement, cell infiltration, and ineffective therapy delivery to systemic circulation has resulted in variable practice with intravenous administration of CAR T cell therapy. With CAR T cell commercialization, it is important to establish practice standards for CAR T cell delivery. We conducted a study to establish usage patterns of mediports in the clinical setting and provide a standard of care recommendation for mediport use as an acceptable form of access for CAR T cell infusions. Methods: In this retrospective cohort study, data on mediport use and infiltration rate was collected from a survey across 34 medical centers in the Pediatric Real-World CAR Consortium, capturing 504 CAR T cell infusion routes across 489 patients. Data represents the largest, and to our knowledge sole, report on clinical CAR T cell infusion practice patterns since FDA approval and CAR T cell commercialization in 2017. Results: Across 34 sites, all reported tunneled central venous catheters, including Broviac® and Hickman® catheters, as accepted standard venous options for CAR T cell infusion. Use of mediports as a standard clinical practice was reported in 29 of 34 sites (85%). Of 489 evaluable patients with reported route of CAR T cell infusion, 184 patients were infused using mediports, with no reported incidences of CAR T cell infiltration. Discussion/Conclusion: Based on current clinical practice, mediports are a commonly utilized form of access for CAR T cell therapy administration. These findings support the safe practice of mediport usage as an accepted standard line option for CAR T cell infusion.

Purpose: The objective of this research is to compare the efficacy of conventional and hypofractionated radiotherapy treatment plans for breast cancer patients, with a specific focus on the unique features of the Halcyon system. Methods and materials: The study collected and analyzed dose volume histogram (DVH) data for two groups of treatment plans implemented using the Halcyon system. The first group consisted of 19 patients who received conventional fractionated (CF) treatment with a total dose of 50 Gy in 25 fractions, while the second group comprised 9 patients who received hypofractionated (HF) treatment with a total dose of 42.56 Gy in 16 fractions. The DVH data was used to calculate various parameters, including tumor control probability (TCP), normal tissue complication probability (NTCP), and equivalent uniform dose (EUD), using radiobiological models. Results: The results indicated that the CF plan resulted in higher TCP but lower NTCP for the lungs compared to the HF plan. The EUD for the HF plan was approximately 49 Gy (114% of its total dose) while that for the CF plan was around 53 Gy (107% of its total dose). Conclusions: The analysis suggests that while the CF plan is better at controlling tumors, it is not as effective as the HF plan in minimizing side effects. Additionally, it is suggested that there may be an optimal configuration for the HF plan that can provide the same or higher EUD than the CF plan.
RESUMO
Objectives: To determine the value of ultrasound (US)-guided synovial biopsy for the diagnosis of infectious arthritis that could not be detected by other modalities. Material and methods: This descriptive study was conducted among 37 patients with arthritis (3 with shoulder arthritis, 2 with elbow arthritis, 7 with wrist arthritis, 15 with hip arthritis, 4 with knee arthritis, and 5 with ankle arthritis) who underwent US-guided synovial biopsy at Hanoi Medical University Hospital for the diagnosis of infec-tious arthritis that could not be detected by infection laboratory tests, imaging, and/or joint fluid culture. The results of US-guided synovial biopsy were positive for infectious arthritis when those of pathologi-cal analyses, bacterial cultures, and/or polymerase chain reaction test for tuberculosis were positive. The final diagnosis established when the patients were discharged from the hospital was compared with the US-guided synovial biopsy results to calculate the sensitivity and specificity for the diagnosis of infectious arthritis. Results: The median age of the patients was 60 years (range: 22-79 years), and two thirds were women. Infectious arthritis was determined as the final diagnosis in 18 patients. There was no significant difference in the infection laboratory test results, synovial thickness, or magnetic resonance imaging features apart from soft tissue abscess between the infectious and non-infectious arthritis groups (P > 0.05). The US-guided synovial biopsy results were positive in 17 patients. Compared with the sensitivity and specificity of the final diagnosis, those of the US-guided synovial biopsy results for the diagnosis of infectious arthritis were 94.4% and 100%, respectively. The Numerical Rating Scale score was ≤3 in most patients. There were neither vascular nor neurologic complications among the patients. Conclusion: Imaging features and laboratory test results are non-specific for infectious arthritis. US-guided synovial biopsy is a well-tolerated, safe method that has a high value for the diagnosis of infectious arthritis. This modality should then be recommended for patients with unclassified arthritis.

Sensitive detection of pathogens in livestock farms is an integral part of the One Health Action Plan of the European Union (EU). Ensuring this requires on-site testing devices that are compatible with complex matrices such as primary production samples. Among all, faeces are considered the most challenging matrix type that makes it difficult to identify pathogens because of complexity in sample preparation for molecular testing. We have developed a loop-mediated isothermal amplification (LAMP) based veterinary point-of-care (POC) device (VETPOD) and adapted it to detect Salmonella enterica in primary production samples. Three different sampling methods (semi-wet chicken faeces, boot socks collection and dust samples from poultry shed) were iteratively tested to assess their nature of complexity and possibility for adapting them as suitable sampling methods for on-site testing. During the study, the sample preparation method that included a two-step centrifugation combined with washing of the enriched Salmonella cells was found crucial in eliminating amplification inhibitors originating from the faecal matrices. A total of 90 samples were tested that included 60 samples for sensitivity study and 30 samples for relative level of detection (RLOD, a level of detection in comparison to ISO 6579:1 reference method). Overall, the VETPOD had a sensitivity of 90%, 84.62% and 81.82% for boot sock, faecal and dust samples, respectively. The RLOD was 2.23 CFU/25 g which was found to be 1.33 times higher than the ISO 6579:1. Performing with an excellent agreement with ISO 6579:1, the VETPOD proved as a promising alternative to detect Salmonella spp. in primary production and animal husbandry samples.

Background: Aquatic plants play a crucial role in nature-based wastewater treatment and provide a promising substrate for renewable energy production using anaerobic digestion (AD) technology. This study aimed to examine the contaminant removal from AD effluent by water lettuce (WL) and produce biogas from WL biomass co-digested with pig dung (PD) in a farm-scale biogas digester. Methods: The first experiment used styrofoam boxes containing husbandry AD effluent. WLs were initially arranged in 50%, 25%, 12.5%, and 0% surface coverage. Each treatment was conducted in five replicates under natural conditions. In the second experiment, WL biomass was co-digested with PD into an existing anaerobic digester to examine biogas production on a farm scale. Results: Over 30 days, the treatment efficiency of TSS, BOD5, COD, TKN, and TP in the effluent was 93.75-97.66%, 76.63-82.56%, 76.78-82.89%, 61.75-63.75%, and 89.00-89.57%, respectively. Higher WL coverage increased the pollutant elimination potential. The WL biomass doubled after 12 days for all treatments. In the farm-scale biogas production, the biogas yield varied between 190.6 and 292.9 L kg VSadded-1. The methane content reached over 54%. Conclusions: WL removed AD effluent nutrients effectively through a phytoremediation system and generated significant biomass for renewable energy production in a farm-scale model.

Accurate and rapid detection of pathogens in foods of animal origin has been a critical part of the One Health Action Plan of the European Union (EU). Biosensors have the potential in bringing required technologies to accomplish this on the field, wherein loop-mediated isothermal amplification (LAMP) and lab-on-a-chip have proven to be ideal. We have developed a LAMP-based point-of-care (POC) device, the VETPOD, as a solution to the contemporary challenges in the rapid detection of Salmonella spp. The core technology in the VETPOD is a ready-to-use cartridge that included an injection-molded polymer chip with pyramid-shaped optical structures embedded within the chip. These pyramid-shaped optical structures direct the incident light, due to total internal reflection (TIR), through the reaction chambers to the phototransistor. The VETPOD was validated against the ISO 6579-1 reference method. A total of 310 samples were tested that included 180 Salmonella spiked samples in 6 different meat categories and 130 strains to determine the specificity. The overall results were satisfactory, wherein the VETPOD had an acceptable sensitivity (96.51%) compared to the reference (98.81%) and near perfect agreement with ISO 6579-1 with an overall Cohen's kappa of 0.94. The relative level of detection (RLOD) for the VETPOD was 1.38 CFU/25 g that was found to be 1.17 times higher than the reference. The VETPOD showed 98% precision for inclusivity and 100% precision for the exclusivity samples. The VETPOD proved as a useful alternative to detect Salmonella spp. that can be adaptable to a broader spectrum of pathogens in future.

Diseases transmitted by mosquitoes and snails cause a large burden of disease in less developed countries, especially those with low-income levels. An approach to control vectors and intermediate hosts based on readily available essential oils, which are friendly to the environment and human health, may be an effective solution for disease control. Guava is a fruit tree grown on a large scale in many countries in the tropics, an area heavily affected by tropical diseases transmitted by mosquitoes and snails. Previous studies have reported that the extracted essential oils of guava cultivars have high yields, possess different chemotypes, and exhibit toxicity to different insect species. Therefore, this study was carried out with the aim of studying the chemical composition and pesticide activities of six cultivars of guava grown on a large scale in Vietnam. The essential oils were extracted by hydrodistillation using a Clevenger-type apparatus for 6 h. The components of the essential oils were determined using gas-chromatography-mass-spectrometry (GC-MS) analysis. Test methods for pesticide activities were performed in accordance with WHO guidelines and modifications. Essential oil samples from Vietnam fell into two composition-based clusters, one of (E)-ß-caryophyllene and the other of limonene/(E)-ß-caryophyllene. The essential oils PG03 and PG05 show promise as environmentally friendly pesticides when used to control Aedes mosquito larvae with values of 24 h LC50-aegypti of 0.96 and 0.40 µg/mL while 24 h LC50-albopictus of 0.50 and 0.42 µg/mL. These two essential oils showed selective toxicity against Aedes mosquito larvae and were safe against the non-target organism Anisops bouvieri. Other essential oils may be considered as molluscicides against Physa acuta (48 h LC50 of 4.10 to 5.00 µg/mL) and Indoplanorbis exustus (48 h LC50 of 3.85 to 7.71 µg/mL) and with less toxicity to A. bouvieri.
RESUMO
BACKGROUND: Prevalence of health workers with occupational health issues ranked fourth among all careers resulting in a reduction in quality of life. However, tools to measure professional quality of life (ProQoL) are unavailable in Vietnamese. This study aims to develop a Vietnamese version of the ProQoL, and examine ProQoL and its associated factors among doctors and nurses. METHODS: The ProQoL is comprised of 30 items measures compassion satisfaction (CS), burnout (BO), and secondary traumatic stress (STS). The tool was translated into Vietnamese following the Guideline by Guillemin et. al (1993), reviewed by expert panels, and validated for internal consistency and test-retest reliability among 38 health workers working at hospitals in HCMC. The validated tool was then used in a cross-sectional study to measure the ProQoL of full-time doctors and nurses working in clinical departments at the University Medical Center, University of Medicine and Pharmacy at Ho Chi Minh City, Vietnam. In addition to the ProQoL, self-reported data about demographic and occupational characteristics were collected. RESULTS: The Vietnamese version of ProQoL achieved high internal consistency (alphas between 0.85 and 0.91) and Intra-class Correlation Coefficients (ICCs between 0.71 and 0.89) for all subscales. Among 316 health workers, mean scores of CS, BO, STS were 36.4 (SD = 5.4), 24.9 (SD = 5.1), 25.9 (SD = 5.3), respectively, indicating moderate levels of CS, BO and STS. Participants who were older (b = 0.17, 95%CI = 0.08, 0.26), had sufficient perceived income (b = 2.59, 95%CI = 0.93, 4.24), and > 10 years of working experience (b = 2.15, 95%CI = 0.68, 3.62), had higher CS scores. Those who were older (b=-0.15, 95%CI=-0.23, -0.07), had sufficient perceived income (b=-2.64, 95%CI=-4.18, -1.09), > 10 years of experience (b=-1.38, 95%CI=-2.76, -0.01), worked in surgical department (b=-1.46, 95%CI=-2.54, -0.38) and 8 hours/day (b=-1.52, 95%CI=-2.61, -0.44), had lower BO scores. Moreover, those in a relationship (b=-2.27, 95%CI=-3.53, -1.01) and had sufficient perceived income (b=-1.98, 95%CI=-3.64, -0.32) had lower STS scores. CONCLUSIONS: The Vietnamese version of ProQoL is valid and reliable for use among Vietnamese health workers. Age, marital status, perceived income status, years of working experience, daily working hours, and specialty was associated with at least one component of ProQoL but gender, religion, education level, and monthly income were not.

Sensitive and rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a vital goal in the ongoing COVID-19 pandemic. We present in this comprehensive work, for the first time, detailed fabrication and clinical validation of a point of care (PoC) device for rapid, onsite detection of SARS-CoV-2 using a real-time reverse-transcription loop-mediated isothermal amplification (RT-LAMP) reaction on a polymer cartridge. The PoC system, namely PATHPOD, consisting of a standalone device (weight less than 1.2 kg) and a cartridge, can perform the detection of 10 different samples and two controls in less than 50 min, which is much more rapid than the golden standard real-time reverse-transcription Polymerase Chain Reaction (RT-PCR), typically taking 16-48 h. The novel total internal reflection (TIR) scheme and the reactions inside the cartridge in the PoC device allow monitoring of the diagnostic results in real-time and onsite. The analytical sensitivity and specificity of the PoC test are comparable with the current RT-PCR, with a limit of detection (LOD) down to 30-50 viral genome copies. The robustness of the PATHPOD PoC system has been confirmed by analyzing 398 clinical samples initially examined in two hospitals in Denmark. The clinical sensitivity and specificity of these tests are discussed.
RESUMO
The period of puberty in youth brings various changes in their psychology which can make their social and emotional development unbalanced. The current study aimed to identify the factors affecting the adolescents social-emotional health. We conducted a cross-sectional study on 600 Vietnamese adolescents selected conveniently from the three regions of Vietnam during the outbreak of COVID-19 pandemic. Factors considered was sociodemographic information and health condition. By using the multiple binary logistic regression, we determined the factors negatively affected adolescents' social-emotional health. In which, religion was found to be the most predictive factor negatively affect the social-emotional health among the adolescents. The individual factors were found to be highly related to the positive experience of social-emotional health. From the findings, we suggest the solutions to prevent the negative experience of social-emotional health among the adolescents from a perspective of practice and develop social-emotional skills.
RESUMO
The demand for accurate control of the flowrate/pressure in chemical analytical systems has given rise to the adoption of mechatronic approaches in analytical instruments. A mechatronic device is a synergistic system which combines mechanical, electronic, computer and control components. In the development of portable analytical devices, considering the instrument as a mechatronic system can be useful to mitigate compromises made to decrease space, weight, or power consumption. Fluid handling is important for reliability, however, commonly utilized platforms such as syringe and peristaltic pumps are typically characterized by flow/pressure fluctuations and slow responses. Closed loop control systems have been used effectively to decrease the difference between desired and realized fluidic output. This review discusses the way control systems have been implemented for enhanced fluidic control, categorized by pump type. Advanced control strategies used to enhance the transient and the steady state responses are discussed, along with examples of their implementation in portable analytical systems. The review is concluded with the outlook that the challenge in adequately expressing the complexity and dynamics of the fluidic network as a mathematical model has yielded a trend towards the adoption of experimentally informed models and machine learning approaches.

Objective: Vaccine hesitancy has been ranked by the World Health Organization among the top 10 threats to global health. With a surge in misinformation and conspiracy theories against vaccination observed during the COVID-19 pandemic, attitudes toward vaccination may be worsening. This study investigates trends in anti-vaccination attitudes during the COVID-19 pandemic and within the United States, Canada, the United Kingdom, and Australia. Methods: Vaccine-related English tweets published between 1 January 2020 and 27 June 2021 were used. A deep learning model using a dynamic word embedding method, Bidirectional Encoder Representations from Transformers (BERTs), was developed to identify anti-vaccination tweets. The classifier achieved a micro F1 score of 0.92. Time series plots and country maps were used to examine vaccination attitudes globally and within countries. Results: Among 9,352,509 tweets, 232,975 (2.49%) were identified as anti-vaccination tweets. The overall number of vaccine-related tweets increased sharply after the implementation of the first vaccination round since November 2020 (daily average of 6967 before vs. 31,757 tweets after 9/11/2020). The number of anti-vaccination tweets increased after conspiracy theories spread on social media. Percentages of anti-vaccination tweets were 3.45%, 2.74%, 2.46%, and 1.86% for the United States, the United Kingdom, Australia, and Canada, respectively. Conclusions: Strategies and information campaigns targeting vaccination misinformation may need to be specifically designed for regions with the highest anti-vaccination Twitter activity and when new vaccination campaigns are initiated.
