Intussusception is a rare condition in adults that occurs when a segment of the bowel telescopes into the lumen of the more distal segment. Colocolic intussusception accounts for only 8.3-38% of all intussusception cases in adults, the majority due to malignant causes such as adenocarcinoma, lymphoma, leiomyosarcoma, undifferentiated carcinoma... Lipoma is the most common benign cause, followed by gastrointestinal stromal tumors and adenomatous polyps. Surgery is the recommended treatment for colonic lipoma-induced intussusception. In this report, we describe a rare case of a 52-year-old female patient with colocolic intussusception due to an ascending colon lipoma which was diagnosed by ultrasound and computed tomography.

To meet the increasing societal demands for the quality of childcare education in preschools and the requirements of the new Preschool Education Program, it is essential that the preschool teaching staff undergo comprehensive improvements in both ethical qualities and professional standards. Using theoretical research methods, reading and analyzing legal documents, examining management and autonomy documents, as well as employing synthesis, statistical, and comparative methods, this article focuses on several key areas: an overview of professional development and preschool teacher training; an analysis of the current state of teacher quality, ethics, and professional development of preschool teachers in Thai Binh; and recommendations for renewing the management of professional development activities to improve the quality of education, take care and upbringing of children in preschools in Thai Binh province in the current period.

This study aimed to investigate the current state of education on the development of children's cooperative abilities via the use of themed role-playing games in Dak Lak, Vietnam. The period between March through June 2019 was devoted to administering an online survey for data collection. The findings indicate that preschools have devoted attention, effort, intellect, and time to developing primary students' collaboration abilities. Despite this, the findings are still relatively low and do not reflect the proportional number of participants. The youngsters aged 5 to 6 years old have shown that the measures benefit their ability to collaborate with others. The youngsters are more engaged in the activity, taking the initiative, and showing enthusiasm for interacting with one another. The experimental and control groups were quite different regarding their ability to collaborate effectively. In comparison to the youngsters in the control group, those in the experimental group demonstrated superior collaboration skills on a more consistent and regular basis.

The wear of roller linear guides (RLG) has a direct impact on the tooling precision of CNC machine tool. Wear depends on working conditions: load P, speed V, work environment which includes relative humidity RH and ambient temperature T. In this paper the mathematical regression function describes the relationship between the wear amount U of RLG with the three factors P, RH and T built on the basis of experimental research. The results show that the wear regression function U has an exponential form, which is consistent with experiments about the influence of climatic environment. It describes the simultaneous impact of three factors P, RH, T that affect wear of CNC machine tool rolling guide. With Vietnam's hot and humid environmental conditions, relative humidity RH% = 51 - 99%, temperature T = 15 - 450C, and load P = 2 - 6kgf, the influence on rolling guide wear of normal load P is 2 times the humidity RH% and about 3.8 times that of temperature T. Therefore, it is possible to predict the change in wear amount according to two environmental factors when loading P at certain values.

The research aims to investigate common mistakes in students' paragraph writing and then suggest some solutions to overcome and enhance students' writing skills. Both quantitative and qualitative methods were employed. Mistakes in the paragraph writing of 60 first-year students were gathered and analyzed. The research results reveal a total of 435 mistakes categorized into three groups: grammar, vocabulary, coherence and four main error causes including grammar and vocabulary weakness, lack of wrtiting practice, Vietnamese interference, and infrequent feedback and correction. Through the findings, several suitable measures have been proposed to assist students in self-correcting their writing mistakes and improving writing skills more effectively. Simultaneously, these measures aim to enhance the effectiveness of teaching writing skills for instructors.

BackgroundThe etiology of ischemic stroke is multifactorial. Several gene mutations have been identified as leading causes of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a hereditary disease that causes stroke and other neurological symptoms. ObjectiveWe aimed to identify the variants of NOTCH3 and thrombophilia genes, and their complex interactions with other factors. MethodsWe conducted a hierarchical cluster analysis (HCA) on the data of 100 patients diagnosed with ischemic stroke. The variants of NOTCH3 and thrombophilia genes were identified by polymerase chain reaction with confronting 2-pair primers and real-time polymerase chain reaction. The overall preclinical characteristics, cumulative cutpoint values, and factors associated with these somatic mutations were analyzed in unidimensional and multidimensional scaling models. ResultsWe identified the following optimal cutpoints: creatinine, 83.67 (SD 9.19) µmol/L; age, 54 (SD 5) years; prothrombin (PT) time, 13.25 (SD 0.17) seconds; and international normalized ratio (INR), 1.02 (SD 0.03). Using the Nagelkerke method, cutpoint 50% values of the Glasgow Coma Scale score; modified Rankin scale score; and National Institutes of Health Stroke Scale scores at admission, after 24 hours, and at discharge were 12.77, 2.86 (SD 1.21), 9.83 (SD 2.85), 7.29 (SD 2.04), and 6.85 (SD 2.90), respectively. ConclusionsThe variants of MTHFR (C677T and A1298C) and NOTCH3 p.R544C may influence the stroke severity under specific conditions of PT, creatinine, INR, and BMI, with risk ratios of 4.8 (95% CI 1.53-15.04) and 3.13 (95% CI 1.60-6.11), respectively (Pfisher

Abstract Background Vietnam is undergoing a rapid epidemiological transition with a considerable burden of non-communicable diseases (NCDs), especially hypertension and diabetes (T2DM). Continuity of care (COC) is widely acknowledged as a benchmark for an efficient health system. This study aimed to determine the COC level for hypertension and T2DM within and across care levels and to investigate its associations with health outcomes and disease control. Methods A cross-sectional study was conducted on 602 people with T2DM and/or hypertension managed in primary care settings. We utilized both the Nijmegen continuity of care questionnaire (NCQ) and the Bice - Boxerman continuity of care index (COCI) to comprehensively measure three domains of COC: interpersonal, informational, and management continuity. ANOVA, paired-sample t-test, and bivariate and multivariable logistic regression analysis were performed to examine the predictors of COC. Results Mean values of COC indices were: NCQ: 3.59 and COCI: 0.77. The proportion of people with low NCQ levels was 68.8%, and that with low COCI levels was 47.3%. Primary care offered higher informational continuity than specialists (p

Abstract Background While many studies on the determinants of post-COVID-19 conditions (PCC) have been conducted, little is known about the relationship between SARS-CoV-2 variants and PCC. This study aimed to assess the association between different SARS-CoV-2 variants and the probability of having PCC three months after the infection. Methods This study was a longitudinal cohort study conducted between April 2021 and September 2022 in Belgium. In total, 8,238 adults with a confirmed SARS-CoV-2 infection were followed up between the time of their infection and three months later. The primary outcomes were the PCC status three months post infection and seven PCC symptoms categories (neurocognitive, autonomic, gastrointestinal, respiratory, musculoskeletal, anosmia and/or dysgeusia, and other manifestations). The main exposure variable was the type of SARS-CoV-2 variants (i.e. Alpha, Delta, and Omicron), extracted from national surveillance data. The association between the different SARS-CoV-2 variants and PCC as well as PCC symptoms categories was assessed using multivariable logistic regression. Results The proportion of PCC among participants infected during the Alpha, Delta, and Omicron-dominant periods was significantly different and respectively 50%, 50%, and 37%. Participants infected during the Alpha- and Delta-dominant periods had a significantly higher odds of having PCC than those infected during the Omicron-dominant period (OR = 1.61, 95% confidence interval [CI] = 1.33–1.96 and OR = 1.73, 95%CI = 1.54–1.93, respectively). Participants infected during the Alpha and Delta-dominant periods were more likely to report neurocognitive, respiratory, and anosmia/dysgeusia symptoms of PCC. Conclusions People infected during the Alpha- and Delta-dominant periods had a higher probability of having PCC three months after infection than those infected during the Omicron-dominant period. The lower probability of PCC with the Omicron variant must also be interpreted in absolute figures. Indeed, the number of infections with the Omicron variant being higher than with the Alpha and Delta variants, it is possible that the overall prevalence of PCC in the population increases, even if the probability of having a PCC decreases.

The paper presents the results of the first research on the synthesis of nano‐ZIF‐90 from zinc chloride. More specifically, the paper also introduces the results of large‐scale pure nano‐ZIF‐90 synthesis with a high specific surface, uniform cubic crystals, and good thermal strength. ZIF‐90 is synthesized from zinc chloride‐containing medium capillaries, which have both a weak acid center and a strong base center. The post‐synthetic ZIF‐90 was also evaluated for heat storage based on its ability to adsorb water, methanol, and ethanol. XRD, FTIR, SEM, TEM, N2 adsorption and desorption methods, TG mass thermal analysis, and NH3‐TPD/CO2‐TPD were used to study the ZIF‐90 crystallization process with modifications of precursors, solvents, additives, and reaction conditions. From this, a large‐scale synthesis of nano‐ZIF‐90 from high‐efficiency zinc chloride has been derived. DSC measurements are used to evaluate the enthalpy adsorption of water, methanol, and ethanol on ZIF‐90. [ABSTRACT FROM AUTHOR]
