MAPL loss dysregulates bile and liver metabolism in mice.

Mitochondrial and peroxisomal anchored protein ligase (MAPL) is a dual ubiquitin and small ubiquitin-like modifier (SUMO) ligase with roles in mitochondrial quality control, cell death and inflammation in cultured cells. Here, we show that MAPL function in the organismal context converges on metabolic control, as knockout mice are viable, insulin-sensitive, and protected from diet-induced obesity. MAPL loss leads to liver-specific activation of the integrated stress response, inducing secretion of stress hormone FGF21. MAPL knockout mice develop fully penetrant spontaneous hepatocellular carcinoma. Mechanistically, the peroxisomal bile acid transporter ABCD3 is a primary MAPL interacting partner and SUMOylated in a MAPL-dependent manner. MAPL knockout leads to increased bile acid production coupled with defective regulatory feedback in liver in vivo and in isolated primary hepatocytes, suggesting cell-autonomous function. Together, our findings establish MAPL function as a regulator of bile acid synthesis whose loss leads to the disruption of bile acid feedback mechanisms. The consequences of MAPL loss in liver, along with evidence of tumor suppression through regulation of cell survival pathways, ultimately lead to hepatocellular carcinogenesis.

Risk factors associated with the severity of pericoronitis of mandibular third molar.

PURPOSE: The factors related to pericoronitis severity are unclear, and this study aimed to address this knowledge gap. MATERIALS AND METHODS: In total, 113 patients with pericoronitis were included, and their demographic, clinical, and radiographic characteristics were recorded. The Patient-Clinician Pericoronitis Classification was used to score and categorize the severity of pericoronitis. Statistical analysis was conducted to examine the participants' characteristics, validity of the Patient-Clinician Pericoronitis Classification, and risk factors associated with the severity of pericoronitis. RESULTS: The demographic, clinical, and radiographic characteristics of males and females were similar, except for Winter's classification, pain, and intraoral swelling. The constructive validity of the Patient-Clinician Pericoronitis Classification was confirmed with three latent factors, including infection level, patient discomfort, and social interference. Ordinal logistic multivariate regression analysis revealed that upper respiratory tract infection was the sole risk factor associated with pericoronitis severity in males (odds ratio = 4.838). In females, pericoronitis on the right side (odds ratio = 2.486), distal radiolucency (odds ratio = 5.203), and menstruation (odds ratio = 3.416) were significant risk factors. CONCLUSION: This study demonstrated the constructive validity of the Patient-Clinician Pericoronitis Classification. Among females, pericoronitis in mandibular third molars on the right side with radiolucency in menstruating individuals was more severe. In males, upper respiratory tract infection was the sole risk factor associated with pericoronitis severity. CLINICAL RELEVANCE: Individuals with risk factors should be aware of severe pericoronitis in the coming future.

Commentary to Skudlik et al. (2023): why a scoping review and why only Germany?

This letter to the editor is a commentary on the scoping review by Skudlik et al. (2023) on the relocation of older people to nursing homes in Germany. In this commentary, we question certain methodological decisions that, in our view, particularly affect transferability of the results and give a partial picture of the phenomena studied by limiting the inclusion to German studies. We also have questions about the choice of knowledge synthesis method and why the concept of "nursing home" was not defined. We hope that this letter will open a constructive scientific discussion on an important topic that is understudied as the world's population ages.

Stress among nursing students in Vietnam: Prevalence and associated factors.

AIM: To describe stress and analyze its associated factors among nursing students. INTRODUCTION: Stress is a common mental health problem among medical students, especially nursing students. Therefore, understanding stress and its associated factors is necessary to improve stress in students. METHODS: A cross-sectional study was conducted among 300 nursing students using the stratified sampling method. This study used questionnaires such as demographic form, the Depression Anxiety Stress Scale 21, and the Stressors in Nursing Students scale. The STROBE checklist was used for reporting this study. RESULTS: Results showed that nearly half of the nursing students were stressed at various levels. Students experienced stress the most due to financial stressors, followed by education, clinical, and confidence stressors. Most of the factors in the four groups-clinical, education, confidence, and finance-increased the risk of stress in nursing students. There was a close relationship between personal problems other than health and the students' risk of stress (p < 0.001). CONCLUSIONS: This study indicated that stress in nursing students was at a high level. Determining the prevalence and associated factors of stress in nursing students will help schools, families, and society take measures to reduce stress among students. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Educational administrators need to develop policies to support nursing students, such as reviewing the academic load of nursing students, improving the design of curricula, and supporting finance for students with difficult situations. Support services should be organized and make it easier for students to access mental health counseling services.

Comparison of Radiologists and Deep Learning for US Grading of Hepatic Steatosis.

Background Screening for nonalcoholic fatty liver disease (NAFLD) is suboptimal due to the subjective interpretation of US images. Purpose To evaluate the agreement and diagnostic performance of radiologists and a deep learning model in grading hepatic steatosis in NAFLD at US, with biopsy as the reference standard. Materials and Methods This retrospective study included patients with NAFLD and control patients without hepatic steatosis who underwent abdominal US and contemporaneous liver biopsy from September 2010 to October 2019. Six readers visually graded steatosis on US images twice, 2 weeks apart. Reader agreement was assessed with use of κ statistics. Three deep learning techniques applied to B-mode US images were used to classify dichotomized steatosis grades. Classification performance of human radiologists and the deep learning model for dichotomized steatosis grades (S0, S1, S2, and S3) was assessed with area under the receiver operating characteristic curve (AUC) on a separate test set. Results The study included 199 patients (mean age, 53 years ± 13 [SD]; 101 men). On the test set (n = 52), radiologists had fair interreader agreement (0.34 [95% CI: 0.31, 0.37]) for classifying steatosis grades S0 versus S1 or higher, while AUCs were between 0.49 and 0.84 for radiologists and 0.85 (95% CI: 0.83, 0.87) for the deep learning model. For S0 or S1 versus S2 or S3, radiologists had fair interreader agreement (0.30 [95% CI: 0.27, 0.33]), while AUCs were between 0.57 and 0.76 for radiologists and 0.73 (95% CI: 0.71, 0.75) for the deep learning model. For S2 or lower versus S3, radiologists had fair interreader agreement (0.37 [95% CI: 0.33, 0.40]), while AUCs were between 0.52 and 0.81 for radiologists and 0.67 (95% CI: 0.64, 0.69) for the deep learning model. Conclusion Deep learning approaches applied to B-mode US images provided comparable performance with human readers for detection and grading of hepatic steatosis. Published under a CC BY 4.0 license.

Sulfur-Promoted Oxidative Condensation of Chalcones with Unsubstituted Cyanoacetamide in DMSO: Access to 3-Cyanopyrid-2-ones.

Elemental sulfur and DABCO were found to be an excellent combination to promote a one-pot cascade of condensation-oxidative cyclization of chalcones and unsubstituted cyanoacetamide in DMSO to provide 3-cyanopyrid-2-ones.

Nanoengineered injectable hydrogels derived from layered double hydroxides and alginate for sustained release of protein therapeutics in tissue engineering applications.

Chronic Kidney Disease (CKD) which involves gradual loss of kidney function is characterized by low levels of a glycoprotein called Erythropoietin (EPO) that leads to red blood cell  deficiency and anemia. Recombinant human EPO (rhEPO) injections that are administered intravenously or subcutaneously is the current gold standard for treating CKD. The rhEPO injections have very short half-lives and thus demands frequent administration with a risk of high endogenous EPO levels leading to severe side effects that could prove fatal. To this effect, this work provides a novel approach of using lamellar inorganic solids with a brucite-like structure for controlling the release of protein therapeutics such as rhEPO in injectable hydrogels. The nanoengineered injectable system was formulated by incorporating two-dimensional layered double hydroxide (LDH) clay materials with a high surface area into alginate hydrogels for sustained delivery. The inclusion of LDH in the hydrogel network not only improved the mechanical properties of the hydrogels (5-30 times that of alginate hydrogel) but also exhibited a high binding affinity to proteins without altering their bioactivity and conformation. Furthermore, the nanoengineered injectable hydrogels (INHs) demonstrated quick gelation, injectability, and excellent adhesion properties on human skin. The in vitro release test of EPO from conventional alginate hydrogels (Alg-Gel) showed 86% EPO release within 108 h while INHs showed greater control over the initial burst and released only 24% of EPO in the same incubation time. INH-based ink was successfully used for 3D printing, resulting in scaffolds with good shape fidelity and stability in cell culture media. Controlled release of EPO from INHs facilitated superior angiogenic potential in ovo (chick chorioallantoic membrane) compared to Alg-Gel. When subcutaneously implanted in albino mice, the INHs formed a stable gel in vivo without inducing any adverse effects. The results suggest that the proposed INHs in this study can be utilized as a minimally invasive injectable platform or as 3D printed patches for the delivery of protein therapeutics to facilitate tissue regeneration.

Updated estimation of the burden of fungal disease in Vietnam.

BACKGROUND: Anecdotally, the burden of fungal diseases in Vietnam is rapidly rising, but there has been no updated estimate on this issue since a previous report in 2015. OBJECTIVES: In this study, we aimed at estimating the incidence and prevalence of serious fungal infections for the year 2020. METHODS: We made estimates with a previously described methodology, using reports on the incidence and prevalence of various established risk factors for fungal infections from local, regional or global sources. RESULTS: We estimated 2,389,661 cases of serious fungal infection occurred in Vietnam in 2020. The most common condition was recurrent vaginal candidiasis (4047/100,000 women annually). Among people living with HIV, we estimated 451 cases of cryptococcal meningitis, 1030 of pneumocystis pneumonia, 166 of histoplasmosis and 1612 of talaromycosis annually. Candidaemia incidence was estimated at 12/100,000 population each year. Owing to its high burden of tuberculosis and respiratory diseases, Vietnam had high rates of severe infections caused by Aspergillus species. Incidence of invasive aspergillosis is 24/100,000 population, allergic bronchopulmonary aspergillosis 78/100,000 and severe asthma with fungal sensitisation 102/100,000. Five-year period prevalence of chronic pulmonary aspergillosis is 120/100,000 population /5-year period. Mucormycosis, fungal keratitis and tinea capitis were estimated at 192, 14,431 and 201 episodes each year, respectively. CONCLUSIONS: The number of patients with mycoses in Vietnam is likely underestimated due to a lack of local data and limited diagnostic capacity, but at least 2.5% of the population might have some form of serious fungal disease.

Adopting the Swenson-like technique for patients with Hirschsprung disease in Vietnam.

PURPOSE: To evaluate outcomes of adopting the Swenson-like technique in transanal pull-through for Hirschsprung disease (HD) at a children's institution in Southeast Asia. METHODS: A retrospective chart review was performed over 42 months at a safety-net pediatric hospital in Vietnam. RESULTS: From January 2019 to June 2022, the Swenson-like technique was implemented and performed on 139 patients (115 male, 24 female, mean age 6.4 ± 11.96 months). There were 123 transanal-only resections, 5 transanal plus laparoscopic, and 11 transanal plus laparotomy. The mean operative time was 70.9 ± 43.6 min. The average length of the resected specimen was 18.8 ± 10.9 cm. No urethral or vaginal injuries occurred. Postoperative complications included 1 anastomotic leak (0.7%), 4 anastomotic stenoses (2.8%), and 2 perianal abscesses in the setting of recurrent enterocolitis (1.4%). With a mean follow-up of 26 ± 11.9 months (range 3-48 months), there were 25 enterocolitis cases (17.9%), 45 patients with constipation (32.3%), 1 episode of fecal incontinence lasting longer than 6 months (0.7%), and 1 rectal-vestibular fistula noted one year postoperatively (0.7%). There were no deaths. CONCLUSION: The Swenson-like technique in transanal pull-through for Hirschsprung's disease was safely adopted at our institution. The results show that applying this technique uniformly in a single institution led to excellent outcomes.

An Overview of the Dry Eye Disease in Sjögren's Syndrome Using Our Current Molecular Understanding.

Sjögren's syndrome is a chronic and insidious auto-immune disease characterized by lymphocyte infiltration of exocrine glands. The patients typically present with ocular surface diseases related to dry eye and other systemic manifestations. However, due to the high prevalence of dry eye disease and the lack of objective and clinically reliable diagnostic tools, discriminating Sjögren's syndrome dry eye (SSDE) from non-Sjögren's syndrome dry eye (NSSDE) remains a challenge for clinicians. Diagnosing SS is important to improve the quality of life of patients through timely referral for systemic workups, as SS is associated with serious systemic complications such as lymphoma and other autoimmune diseases. The purpose of this article is to describe the current molecular understanding of Sjögren's syndrome and its implications for novel diagnostic modalities on the horizon. A literature review of the pre-clinical and clinical studies published between 2016 and 2022 was conducted. The SSDE pathophysiology and immunology pathways have become better understood in recent years. Novel diagnostic modalities, such as tear and saliva proteomics as well as exosomal biomarkers, provide hope on the horizon.

Advances in the Pathogenesis and Treatment of Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a genetically predisposed, female-predominant disease, characterized by multiple organ damage, that in its most severe forms can be life-threatening. The pathogenesis of SLE is complex and involves cells of both innate and adaptive immunity. The distinguishing feature of SLE is the production of autoantibodies, with the formation of immune complexes that precipitate at the vascular level, causing organ damage. Although progress in understanding the pathogenesis of SLE has been slower than in other rheumatic diseases, new knowledge has recently led to the development of effective targeted therapies, that hold out hope for personalized therapy. However, the new drugs available to date are still an adjunct to conventional therapy, which is known to be toxic in the short and long term. The purpose of this review is to summarize recent advances in understanding the pathogenesis of the disease and discuss the results obtained from the use of new targeted drugs, with a look at future therapies that may be used in the absence of the current standard of care or may even cure this serious systemic autoimmune disease.

Ethical principles for artificial intelligence in education.

The advancement of artificial intelligence in education (AIED) has the potential to transform the educational landscape and influence the role of all involved stakeholders. In recent years, the applications of AIED have been gradually adopted to progress our understanding of students' learning and enhance learning performance and experience. However, the adoption of AIED has led to increasing ethical risks and concerns regarding several aspects such as personal data and learner autonomy. Despite the recent announcement of guidelines for ethical and trustworthy AIED, the debate revolves around the key principles underpinning ethical AIED. This paper aims to explore whether there is a global consensus on ethical AIED by mapping and analyzing international organizations' current policies and guidelines. In this paper, we first introduce the opportunities offered by AI in education and potential ethical issues. Then, thematic analysis was conducted to conceptualize and establish a set of ethical principles by examining and synthesizing relevant ethical policies and guidelines for AIED. We discuss each principle and associated implications for relevant educational stakeholders, including students, teachers, technology developers, policymakers, and institutional decision-makers. The proposed set of ethical principles is expected to serve as a framework to inform and guide educational stakeholders in the development and deployment of ethical and trustworthy AIED as well as catalyze future development of related impact studies in the field.

Base-catalyzed multicomponent access to quinoxalin-2-thiones from o-phenylenediamines, aryl ketones and sulfur.

3-Arylquinoxaline-2-thiones were conveniently synthesized via three-component oxidative condensation of acetophenones with o-phenylenediamines and sulfur in DMSO in the presence of piperidine as a catalyst. The products could be readily isolated from the reaction mixture by simple precipitation and washing with methanol. This set of reaction conditions applied to higher homologs of acetophenones as well as benzyl phenyl ketones led to 2,3-di-C-substituted quinoxalines. Further functionalization of 3-phenylquinoxaline-2-thione via reaction on the thione group could be readily performed to provide quinoxaline derivatives in good yields.

Risk factors for disease severity and mortality of children with Covid-19: A study at a Vietnamese Children's hospital.

INTRODUCTION: To find out risk factors for disease severity and mortality of pediatric COVID-19 in the fourth wave of COVID-19 in Vietnam. METHODS: This retrospective cohort study was performed at Children's Hospital 1 from July to December 2021. All children with COVID-19 confirmed by a positive Realtime RT-PCR SARS-CoV-2 result and treated at COVID-19 department for at least 72 h were included. RESULTS: Of the 850 cases admitting to COVID-19 department, 555 children with COVID-19 confirmed by positive RT-PCR and treated at our center for more than 72 h. Median age of confirmed cases was 22.3 (IQR: 3.2-88.6) months, 55.1% were male, and 84.5% had a history of close contact with confirmed COVID-19 patients. The rate of mild, moderate and severe/critical cases was 73,7%, 9.0% and 17.3%, respectively. One hundred ninety-two children (34.6%) had underlying diseases, in which, neurologic disease was the most common underlying disease (7.9%). Underlying disease, dyspnea, elevated CRP >20 mg/L and elevated ferritin were independent factors related to severe illness. Twenty-point two percent of patients in our study needed respiratory support, including 22 invasive mechanical ventilation cases. Eighteen cases (3.2%) died because of severe comorbidities, poor response to treatment. CONCLUSIONS: In our study, the severe/critical and mortality rates in pediatric COVID-19 cases were relatively high. All fatal cases had severe comorbidities. Underlying disease, dyspnea, and elevated inflammatory markers were independent factors related to severity in pediatric COVID-19 cases.

Vinblastine loaded on graphene quantum dots and its anticancer applications.

AIMS: The aim of our work is to load Vinblastine drugs loaded on graphene quantum dots to improve its cytotoxicity on cancer cells and reduce it on the normal cell in the composites. Moreover, the GQDs-Vin composite significantly inhibited tumour growth in animals. METHODS: GQDs-Vin composites were prepared by homogenisation of GQDs and Vin solutions. The loading of Vin on GQDs in the composites was characterised by FTIR, PL, UV-vis spectra, and TEM. The cytotoxicity of GQDs, Vin, and GQDs-Vin composites was investigated on the Hela, HGC-27, A549, MCF-7, CCF-STTG1 cells and Vero by in vitro and in vivo methods. The difference in cellular structure and organelles in mice's livers in comparison between the control group and GQDs-Vin (1:5) groups was characterised by TEM. RESULTS: The diameter of the nanoparticles of GQDs-Vin composites in weight ratios 1:1, 1:3 and 1:5 w/w of 50-70 nm, 100-150 nm and ∼500nm, respectively, is larger than that of GQDs of 10-50nm. The in vitro results showed that GQDs not only improved the cytotoxicity of Vin to cancer cells but also decreased its cytotoxicity towards normal cells in the composites. The GQDs-Vin (1:5) composite exhibited a stronger tumour inhibition effect than Vin alone. The morphology of mice's livers showed the absence GQDs-Vin nanoparticles in the mice livers suggesting the lack of storage and the leakage from the liver without any toxicity. CONCLUSIONS: Results of the improved cytotoxicity of GQDs-Vin composite on cancer cells, its reduced cytotoxicity on normal cells and the significant inhibition on tumour growth of GQDs-Vin composite compared with Vin and GQDs alone may indicate a synergistic effect of Vin and GQDs in their composites for anticancer application.

Health information diffusion on Twitter: The content and design of WHO tweets matter.

BACKGROUND: Micro-blogging services empower health institutions to quickly disseminate health information to many users. By analysing user data, infodemiology (i.e. improving public health using user contributed health related content) can be measured in terms of information diffusion. OBJECTIVES: Tweets by the WHO were examined in order to identify tweet attributes that lead to a high information diffusion rate using Twitter data collected between November 2019 and January 2020. METHODS: One thousand hundred and seventy-seven tweets were collected using Python's Tweepy library. Afterwards, k-means clustering and manual coding were used to classify tweets by theme, sentiment, length and count of emojis, pictures, videos and links. Resulting groups with different characteristics were analysed for significant differences using Mann-Whitney U- and Kruskal-Wallis H-tests. RESULTS: The topic of the tweet, the included links, emojis and (one) picture as well as the tweet length significantly affected the tweets' diffusion, whereas sentiment and videos did not show any significant influence on the diffusion of tweets. DISCUSSION: The findings of this study give insights on why specific health topics might generate less attention and do not showcase sufficient information diffusion. CONCLUSION: The subject and appearance of a tweet influence its diffusion, making the design equally essential to the preparation of its content.

Stigma as a barrier to integrated substance use and HIV care in Vietnam: A qualitative examination of patient and provider perspectives.

Integration of substance use disorder (SUD) treatment and HIV care can increase antiretroviral therapy coverage among people with opioid use disorder (OUD). However, implementation of integrated treatment models remains limited. Stigma towards people with OUD poses a barrier to initiation of, and adherence to, HIV treatment. We sought to understand the extent of stigma towards SUD and HIV among people with OUD in Vietnam, and the effect of stigma on integrated OUD and HIV treatment services utilization. Between 2013 and 2015, we conducted in-depth interviews with 43 patients and 43 providers at 7 methadone clinics and 8 HIV clinics across 4 provinces in Vietnam. We used thematic analysis with a mixed deductive and inductive approach at the semantic level to analyze key topics. Two main themes were identified: (1) Confidentiality concerns about HIV status make patients reluctant to receive integrated care at HIV clinics, given the requirements for daily buprenorphine dosing at HIV clinics. (2) Provider stigma existed mostly toward people with OUD and seemed to center on the belief that substance use causes a deterioration in one's morals, and was most frequently manifested in the form of providers' apprehensive approach towards patients. Concerns regarding stigmatization may cause patients to feel reluctant to receive treatment for both OUD and HIV at a single integrated clinic. Interventions to reduce stigma at the clinic and policy levels may thus serve to improve initiation of and adherence to integrated care.

Azole-resistant Aspergillus fumigatus is highly prevalent in the environment of Vietnam, with marked variability by land use type.

Azole-resistant environmental Aspergillus fumigatus presents a threat to public health but the extent of this threat in Southeast Asia is poorly described. We conducted environmental surveillance in the Mekong Delta region of Vietnam, collecting air and ground samples across key land-use types, and determined antifungal susceptibilities of Aspergillus section Fumigati (ASF) isolates and azole concentrations in soils. Of 119 ASF isolates, 55% were resistant (or non-wild type) to itraconazole, 65% to posaconazole and 50% to voriconazole. Azole resistance was more frequent in A. fumigatus sensu stricto isolates (95%) than other ASF species (32%). Resistant isolates and agricultural azole residues were overrepresented in samples from cultivated land. cyp51A gene sequence analysis showed 38/56 resistant A. fumigatus sensu stricto isolates carried known resistance mutations, with TR34 /L98H most frequent (34/38).

Age, operation time and surgical approach can be used to detect incidental gallbladder carcinoma in cholecystectomy specimens from low-incidence settings.

AIMS: Gallbladders resected for non-neoplastic diseases are systemically examined microscopically to rule out incidental dysplasia and carcinoma. The main aim of this study was to test whether a pre-grossing algorithm can detect incidental gallbladder carcinoma. The secondary aim was to test whether the algorithm can detect high-grade dysplasia. METHODS AND RESULTS: A retrospective study of clinical, pathological and radiological findings in cholecystectomy recipients was performed on a test set to develop a classification and regression tree algorithm. Cholecystectomy cases were included; exclusion criteria were age <18 years, missing pathology reports, preoperative suspicion of neoplastic disease, and cholecystectomy for non-gallbladder oncological disease. Five thousand nine hundred and eighty-two cholecystectomies from 2006 to 2018 were included in the study, with 18 cases of incidental gallbladder carcinoma and 11 cases of high-grade dysplasia. Three hundred and ninety controls were randomly selected for the testing set. Patient age, surgical approach, operation duration, dilatation of the biliary tract and gallbladder gross anomalies were statistically significant distinguishing factors in multivariate analysis (P < 0.00-0.026). Unsupervised testing with a conditional inference tree suggested that age, procedure type and operation duration can be used to identify incidental gallbladder carcinoma from controls, whereas high-grade dysplasia also requires grossing parameters to identify half of the cases (5/11). CONCLUSION: Readily available clinical parameters and postoperative data can be used to detect incidental gallbladder carcinoma. High-grade dysplasia mostly requires grossing and microscopic examination.
