ABSTRACT

Objectives: Post-operative urinary retention (POUR) is a frequent complication following surgical procedures, characterized by an acute inability to void, leading to additional complications and extended hospitalization. Acupuncture has been shown to be effective in facilitating spontaneous urination and alleviating anxiety in patients experiencing poor urination. The present study aims to evaluate the effectiveness of electroacupuncture in the management of POUR in patients who have undergone lumbar spine surgery. Methods: This retrospective study conducted at the National Hospital of Acupuncture in Vietnam and reviewed the medical records of patients over 18 years old who underwent lumbar spine surgery and were diagnosed with POUR between January to December 2019. Electroacupuncture was administered at five specific acupuncture points Qugu (CV2), Zhongji (CV3), Zhibian (BL54), Pangguanshu (BL28), and Kunlun (BL60). This study monitored key parameters related to the effectiveness of the acupuncture treatment, including the number of acupuncture treatment sessions required until a patient was successfully treated was recorded, with a maximum of three acupuncture treatment sessions per patient, the time elapsed until urination following the treatment (minutes), and urinary bladder volume before and after treatment (mL). Results: The study demonstrated a 93.3% success rate in treating POUR with electroacupuncture. A significant reduction in post-void residual volume was noted, and patients could void within 30 minutes post-treatment. No significant differences in treatment effectiveness were observed across difference genders and age groups. Conclusion: Electroacupuncture proved to be a highly effective treatment for POUR in patients post-lumbar spine surgery, with a rapid response time and substantial reduction in PVR. However, the retrospective nature of the study and single-center focus limit its generalizability. Future research incorporating randomized controlled trials or multi-center observational studies are recommended to validate these findings and explore the potential of acupuncture in POUR management on a broader scale.

ABSTRACT

BACKGROUND: Dengue epidemics impose considerable strain on healthcare resources. Real-time continuous and non-invasive monitoring of patients admitted to the hospital could lead to improved care and outcomes. We evaluated the performance of a commercially available wearable (SmartCare) utilising photoplethysmography (PPG) to stratify clinical risk for a cohort of hospitalised patients with dengue in Vietnam. METHODS: We performed a prospective observational study for adult and paediatric patients with a clinical diagnosis of dengue at the Hospital for Tropical Disease, Ho Chi Minh City, Vietnam. Patients underwent PPG monitoring early during admission alongside standard clinical care. PPG waveforms were analysed using machine learning models. Adult patients were classified between 3 severity classes: i) uncomplicated (ward-based), ii) moderate-severe (emergency department-based), and iii) severe (ICU-based). Data from paediatric patients were split into 2 classes: i) severe (during ICU stay) and ii) follow-up (14-21 days after the illness onset). Model performances were evaluated using standard classification metrics and 5-fold stratified cross-validation. FINDINGS: We included PPG and clinical data from 132 adults and 15 paediatric patients with a median age of 28 (IQR, 21-35) and 12 (IQR, 9-13) years respectively. 1781 h of PPG data were available for analysis. The best performing convolutional neural network models (CNN) achieved a precision of 0.785 and recall of 0.771 in classifying adult patients according to severity class and a precision of 0.891 and recall of 0.891 in classifying between disease and post-disease state in paediatric patients. INTERPRETATION: We demonstrate that the use of a low-cost wearable provided clinically actionable data to differentiate between patients with dengue of varying severity. Continuous monitoring and connectivity to early warning systems could significantly benefit clinical care in dengue, particularly within an endemic setting. Work is currently underway to implement these models for dynamic risk predictions and assist in individualised patient care.

ABSTRACT

BACKGROUND: There are several types of benign renal diseases, such as urological stones, ureteropelvic junction obstruction, renal vascular disease, and inflammation, which are responsible for nonfunctioning kidneys. Laparoscopic nephrectomy (LN) is the gold standard for treating nonfunctioning kidneys with complications. This study presents the results of our initial experiences with 3D laparoscopic nephrectomy (3D-LN) for benign, nonfunctioning kidneys. METHODS: From July 2021 to July 2023, 40 consecutive patients who underwent 3D transperitoneal laparoscopic nephrectomy were retrospectively evaluated at the Department of Urology and Department of General Surgery, Hue Central Hospital, Hue, Vietnam. Patient demographics, intraoperative and early postoperative results, postoperative recovery, complications, and three-month follow-up results were recorded. RESULTS: The mean age was 58.35 ± 14.9 years. There were 13 (32.5%) male and 27 (67.5%) female patients. Flank pain was the main reason for hospitalization in 33 cases (82.5%); the common cause of a nonfunctioning kidney was urological stones (62.5%). Twenty-three out of 40 patients underwent a left nephrectomy. The average operative time was 92.57 ± 28.69 minutes. A statistically significant difference in surgery time was found between the group with no adhesion and the group with mild adhesion, as well as between the first 19 patients and the last 18 patients (p <0.05). The mean blood loss was 51.62 ± 24.35 ml. Three cases were converted to open surgery due to severe adhesions. The postoperative complications rate was 8.1%. The average length of the postoperative hospital stay was 7.89 ± 3.59 days. CONCLUSIONS: Three-dimensional laparoscopic nephrectomy is a safe and effective method that increases depth perception and spatial orientation for surgeons and can compensate for the remaining shortcomings of traditional 2D systems.

ABSTRACT

α-Glucosidase is one of the therapeutic approaches for treating type 2 diabetes mellitus. Almost 95 % of diabetes patients worldwide have been diagnosed with type 2 diabetes, resulting in 1.5 million fatalities each year. Newly synthesized oxazole-based tanshinone IIA derivatives (1a-n) were designed and evaluated for their inhibitory activity against α-glucosidase enzyme. Eight compounds (1a-d, 1f-g, 1j, and 1m) demonstrated excellent inhibition with IC50 values ranging from 0.73 ± 0.11 to 9.46 ± 0.57 µM as compared to tanshinone IIA (IC50 = 11.39 ± 0.77 µM) and standard acarbose (IC50 = 100.00 ± 0.95 µM). Among this series, 1j bearing two hydroxyls group over the phenyl ring was identified as the most potent α-glucosidase inhibitor with IC50 value of 0.73 ± 0.11 µM. Molecular docking simulations were done for the most active compound to identify important binding modes responsible for inhibition activity of α-glucosidase. In addition, the kinetic study was also performed to understand the mode of inhibition.

ABSTRACT

In the Mekong Delta Vietnam, rice is heavily affected by Al3+ and Fe2+ ions appearing in local acid sulfate soils (AAS). Therefore, the current study was carried out to assess the efficacy of a liquid biofertilizer (LB) containing nitrogen-fixing and phosphorus-solubilizing bacterial strains of Rhodopseudomonas spp. on remediation of soil characteristics and improvements of rice uptakes, growth, and yield. The experiment was designed in a randomized block design with nine treatments and four replications in an ASS. The results have shown that the LB application could contribute to the remediation of soil properties, including an increase in concentrations of NH4+ by 12.9%-19.4%, soluble P by 25.7%-42.6%, total N uptake by 40.7-64.0 kg ha-1 and total P uptake by 5.60-12.6 kg ha-1, and a decrease in concentrations of toxins, such as Al3+ by 12.1%-19.7% and Fe2+ by 16.6%-19.0%, compared to the treatment with the farmer-based fertilization. Thereby, grain yield was improved by 31.9%-32.2% with the LB versus the treatments without the bacteria and by 9.5%-11.1% compared to the commercial biofertilizer treatments. The application of LB reduced 25% N and 50% P of the recommendation versus the farmers' fertilization and improved performance of rice growth and yield cultivated on ASS which suffered from Al3+ and Fe2+ ions.


The current study has introduced the potential of the Rhodopseudomonas palustris TLS06, VNW02, VNW64, and VNS89 strains in performance as a bioremediator and a biofertilizer. The strains have shown their ability to recover acid sulfate soils, which had damaged the yield of rice plants due to high concentrations of Al3+ and Fe2+ ions. The work has delivered a biological approach to improve acid sulfate soil fertility and rice productivity in Vietnam and in other parts of the world, which have similar conditions, to achieve sustainable agriculture and food security.

ABSTRACT

BACKGROUND: This paper reports the preparation of a new family of spiked gold nanoparticles, spiked gold nanobipyramids (SNBPs). This protocol includes the process to synthesize gold nanobipyramids (NBPs) using combined seed-mediated and microwave-assisted method and procedure to form spikes on whole surface of gold nanobipyramid. We also evaluated the antibacterial activity against both methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) in various concentrations of SNBPs and NBPs by well diffusion assay, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) determination. The effect of SNBPs on exposed bacteria was observed by scanning electron microscopy. RESULTS: The UV-Vis of purified NBPs exhibited two absorption bands located at 550 nm and 849 nm with yield of bipyramidal particles more than 90%. The average size of NBPs was 76.33 ± 10.11 nm in length and 26.57 ± 2.25 nm in diameter, respectively, while SNBPs were prolongated in length and achieved 182.37 ± 21.74 nm with multi-branches protruding whole surface areas. In antibacterial evaluations, SNBPs and NBPs showed antibacterial activity with MIC of 6.25 µl/ml and 12.5 µl/ml, respectively, for MSSA while 12.5 µl/ml and 25 µl/ml, respectively, for MRSA. Besides, MBC values of SNBPs and NBPs were found to be 12.5 µl/ml and 25 µl/ml, respectively, against MSSA while 25 µl/ml and 50 µl/ml, respectively, against MRSA. Furthermore, scanning electron microscopy observation showed the mechanism that SNBPs damaged the outer membrane, released cytoplasm, and altered the normal morphology of MRSA and MSSA, leading to bacterial death. CONCLUSIONS: This report suggests that these SNBPs are potential antibacterial agents that can be applied as antibacterial materials to inhibit the growth of human bacterial pathogen infections related to antibiotic-resistant bacteria.

ABSTRACT

Background: Although smoking is a known potential contributor to back pain, there is still a lack of quantitative studies on the effects of different doses on back pain (BP) occurrence, including a lack of a longitudinal cohorts. To address this gap, we aimed to investigate the association between various smoking-related exposures and back pain incidence to advance global efforts toward smoking cessation and guide primary prevention of BP. Methods: In this prospective cohort study, we retrieved data on 438 510 patients from the UK Biobank who were free of back pain and who were recruited in 2006-2010, and followed them up from baseline through 1 April 2022. We extracted data on smoking-related exposures, including smoking status (SS), number of cigarettes smoked daily (CPD), and pack-years of own smoking (PY) and examined back pain incidence as an outcome. We used a Cox proportional hazard model adjusted for several covariates, multiple imputation methods, and population attribution fraction. Results: During the median follow-up of 12.98 years, 31 467 participants developed BP, with incidence rates in former and current smokers of 1.13 (95% confidence interval (CI) = 1.10-1.16, P < 0.000) and 1.50 (95% CI = 1.45-1.56, P < 0.000), respectively. The hazard ratios (HRs) of participants who smoked more than 30 CPD and those with more than 30 PY were 1.45 (95% CI = 1.36-1.55, P < 0.000) and 1.45 (95% CI = 1.40-1.50, P < 0.000), respectively. Relative to male, female smokers were at more risk of developing BP. Not smoking, quitting smoking, and reducing CPD and PY could lower the BP risk by 7.8%, 5.4%, 9.8%, and 18.0%, respectively. Conclusions: Ever smoking, higher cigarette consumption daily, and increased smoking intensity were associated with an increased BP risk. This association was stronger in female smokers. Not smoking, smoking cessation, and reducing smoking volume and intensity were effective measures to prevent BP occurrence.

ABSTRACT

Osteoarthritis (OA) is the degeneration of cartilage in joints that results in bones rubbing against each other; it causes uncomfortable symptoms such as pain, swelling, and stiffness and can lead to disability. It usually occurs in the elderly and causes a large medical burden. The aim of this study is to evaluate the cost-effectiveness between the standard treatment for osteoarthritis and standard treatment with added crystalline glucosamine sulfate at various stages. Markov analysis modeling was applied to evaluate the effect of both adding glucosamine compared to standard treatment from a societal perspective during whole patients' lifetimes. Data input was collected from reviews in previous studies. The outcome was measured in quality-adjusted life years (QALYs), and the Incremental Cost-Effectiveness Ratio (ICER) from a societal perspective was applied with 3% and discounted for all costs and outcomes. One-way analysis via the Tornado diagram was performed to investigate the change in factors in the model. In general, adding glucosamine into the standard treatment proved to be more cost-effective compared to the standard treatment. Particularly, the early-stage addition of glucosamine in the treatment was cost-effective compared to the post-stage addition of glucosamine. The addition of supplementing crystalline glucosamine sulfate to the whole regimen at any stage was cost-effective at the willingness-to-pay (WTP) threshold.

ABSTRACT

Osteoarthritis (OA) is a chronic condition that most frequently affects older adults. It is currently the most common disability. The cost of treating an aging population places pressure on the healthcare budget. As a result, it is imperative to evaluate medicines' cost-effectiveness and, accordingly, their influence on health resource allocation. Our study aims to summarize the cost and outcome of utilizing glucosamine in OA treatment. Databases like Medline, Cochrane, and Scopus were searched as part of the identification process up until April 2023. Our primary inclusion criteria centered on the economic evaluation of glucosamine in OA treatments, providing an incremental cost-effectiveness ratio (ICER). The Quality of Health Economic Studies (QHES) instrument was applied to grade the quality of the studies. Seven qualified studies that discussed the cost-effectiveness of glucosamine with or without other formulations were selected. All of them demonstrated that glucosamine was cost-effective. There was an increase in quality-adjusted life years (QALYs) when incorporating glucosamine in conventional care. Moreover, patented crystalline glucosamine sulfate (pCGS) was more cost-effective than the other formulations of glucosamine (OFG). Overall, utilizing pCGS was more beneficial than using OFG in terms both of cost and quality of life.

ABSTRACT

Knee osteoarthritis is the most popular type of osteoarthritis that causes extreme pain in the elderly. Currently, there is no cure for osteoarthritis. To lessen clinical symptoms, glucosamine was suggested. The primary goal of our systematic review study is to evaluate the effectiveness and safety of glucosamine based on recent studies. Electronic databases such as PubMed, Scopus, and Cochrane were used to assess the randomized controlled trial (RCT). From the beginning through March 2023, the papers were checked, and if they fulfilled the inclusion criteria, they were then examined. The Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and Visual Analog Scale (VAS) scales were considered the main outcome measures. A total of 15 studies were selected. Global pain was significantly decreased in comparison to placebo, as measured by the VAS index, with an overall effect size of standardized mean difference (SMD) of -7.41 ([95% CI] 14.31, 0.51). The WOMAC scale confirmed that pain, stiffness, and physical function had improved, however the effects were insufficient. A statistical update also revealed that there were no reports of serious medication interactions or significant adverse events. To summarize, glucosamine is more effective than a placebo at reducing pain in knee osteoarthritis patients. In long-term treatment, oral glucosamine sulfate 1500 mg/day is believed to be well tolerated.

ABSTRACT

Background: We aimed to determine vaccine hesitancy and the main barriers associated with the 2019 novel coronavirus, SARS-CoV-2 (COVID-19) vaccination among families of children diagnosed with food/drug/environmental allergies. Methods: Between May and June 2021, we approached 146 families seen at the outpatient allergy clinic at the Montreal Children's Hospital and a community allergy practice were invited to complete an anonymous online survey on COVID-19 and vaccination attitudes and behaviour. Uni and multivariable logistic regressions were compared to estimate factors associated with vaccine hesitancy. Results: Among all patients, 24.1% reported vaccine hesitancy. The large majority of parents (95.2%) believed that vaccines work. The most common barrier to vaccination was fear of adverse side effects (57.0%). One-third of participants (31.5%) reported that a history of food, venom and drug allergy was a contraindication for COVID-19 vaccination. Fifty-nine (60.8%) participants stated that the dissemination of additional information would increase their willingness to be vaccinated. Most (96.9%) parents reported that their children's vaccinations were up to date. Hesitant families were more likely to be parents of children aged 6-10 years, be of Asian descent, report that mRNA vaccines are riskier than traditional vaccines, and report that the vaccine should not be given if the child has a history of allergic reaction to vaccines. Conclusion: Vaccine hesitancy exists mainly among certain ethnic groups and families with young children. Allergies to food, venom and drug allergy are commonly perceived as contraindications for COVID-19 vaccination. Knowledge translation activities addressing parental concerns will help increase vaccination rates.

ABSTRACT

Few-shot learning is proposed to tackle the problem of scarce training data in novel classes. However, prior works in instance-level few-shot learning have paid less attention to effectively utilizing the relationship between categories. In this paper, we exploit the hierarchical information to leverage discriminative and relevant features of base classes to effectively classify novel objects. These features are extracted from abundant data of base classes, which could be utilized to reasonably describe classes with scarce data. Specifically, we propose a novel superclass approach that automatically creates a hierarchy considering base and novel classes as fine-grained classes for few-shot instance segmentation (FSIS). Based on the hierarchical information, we design a novel framework called Soft Multiple Superclass (SMS) to extract relevant features or characteristics of classes in the same superclass. A new class assigned to the superclass is easier to classify by leveraging these relevant features. Besides, in order to effectively train the hierarchy-based-detector in FSIS, we apply the label refinement to further describe the associations between fine-grained classes. The extensive experiments demonstrate the effectiveness of our method on FSIS benchmarks. The source code is available here: https://github.com/nvakhoa/superclass-FSIS.

ABSTRACT

Background: Upper limb balance is one of the important physical fitness parameters for all populations, especially overhead athletes like swimmers. Upper extremity star excursion balance test (UESEBT) is a comprehensive dynamic balance assessment, this study aims to explore the reliability and validity of UESEBT among adolescent swimmers. Methods: This cross-sectional study recruited 70 adolescent swimmers. All participants were required to complete UESEBT, upper quarter Y-balance test (UQYBT), maximal isometric strength (MIS) tests in upper limb, closed kinetic chain upper extremity stability test (CKCUEST), trunk flexor endurance test (TFET) and lateral trunk endurance test (LTET). The intra- and inter-operator reliability and the correlation of UESEBT with other physical performances were conducted. Results: For reliability, the intra- and inter-operator reliability of all directions and composite score were high-to-excellent (ICC = 0.706-1.000) among all participants. For validity, the UESEBT has a moderate-to-strong correlation with UQYBT (r = 0.42-0.72, p < 0.001), and a weak-to moderate one with CKCUEST (r = 0.25-0.42, p < 0.05). Furthermore, the UESEBT performance showed weak-to-moderate correlations with MIS (r = 0.24-0.44, p < 0.05). UESEBT was correlated to LTET (r = 0.24-0.33, p < 0.05) whereas no relationship was found with TFET. Conclusions: UESEBT was a reliable and valid tool to screen upper extremity dynamic balance among adolescent swimmers. UESEBT provides more detailed information in eight directions to assess the upper limb sport performance. Further study should explore the prediction ability of UESEBT for injury.

ABSTRACT

Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has become one of the most serious public health crises worldwide. Most infected people are asymptomatic but are still able to spread the virus. People with mild or moderate illnesses are likely to recover without hospitalization, while critically ill patients face a higher risk of organ injury or even death. In this study, we aimed to identify a novel biomarker that can predict the severity of COVID-19 patients. Clinical information and RNA-seq data of leukocytes from whole blood samples with and without a COVID-19 diagnosis (n = 100 and 26, respectively) were retrieved from the National Center for Biotechnology Information Gene Expression Omnibus database. Raw data were processed using the Transcripts Per Million (TPM) method and then transformed using log2 (TPM+1) for normalization. The CD24-CSF1R index was established. Violin plots, Kaplan-Meier curves, ROC curves, and multivariate Cox proportional hazards regression analyses were performed to evaluate the prognostic value of the established index. The CD24-CSF1R index was significantly associated with ICU admission (n = 50 ICU, 50 non-ICU) and ventilatory status (n = 42 ventilation, 58 non-ventilation) with p = 4.186e-11 and p = 1.278e-07, respectively. The ROC curve produced a relatively accurate prediction of ICU admission with an AUC of 0.8524. Additionally, patients with a high index had significantly fewer mechanical ventilation-free days than patients with a low index (p = 6.07e-07). Furthermore, the established index showed a strong prognostic ability for the risk of using a ventilator in the multivariate Cox regression model (p < 0.001). The CD24-CSF1R index was significantly associated with COVID-19 severity. The established index could have potential implications for prognosis, disease severity stratification, and clinical management.

ABSTRACT

This study aimed to evaluate the miscibility of cellulose derivatives to improve the release rate and stability of microparticles containing the weakly basic drug itraconazole (ITZ). We also investigated the effect of some organic acids on the microenvironmental pH (pHm) and the release rate of ITZ from the cellulose-based microparticles. The synergistic effect of cellulose-based microparticles and pHm modulators on the bioavailability of ITZ compared with the reference product was investigated in a rabbit model. Differential scanning calorimetry and Fourier-transform infrared spectroscopy (FTIR) analysis showed that ITZ, hydroxypropyl methylcellulose, and hydroxypropyl methylcellulose phthalate were miscible at a ratio of 1.5:3:1 (w/w/w), and the stability of the microparticles was maintained for 6 months under accelerated conditions. In addition, X-ray diffraction, FTIR, and scanning electron microscopy were used to characterize the properties of the microparticles. Through the titration technique and determination of pHm, the combination of fumaric acid and maleic acid (1:2, w/w) was found to be the most effective pHm modulator for microparticles. The integration of cellulose-based microparticles and pHm modulators showed a synergistic effect on the flux and relative bioavailability of ITZ and its active metabolite OH-ITZ (182.60 % and 217.67 %, respectively) when compared with the reference product.
