Care needs assessment of older adults with dementia in a semi-rural district in Vietnam: A community-based cross-sectional study.

BACKGROUND: The increasing needs of people living with dementia (PLWD) in Vietnam present an enormous public health challenge. Vietnam is an understudied country, and little is known regarding the overall unmet needs of caregivers or the demographic risk factors associated with unmet caregiving needs. This study aimed to determine the burden of unmet care needs of community-dwelling PLWD and identify sociodemographic risks associated with unmet care needs. METHODS: A cross-sectional study in a rural area facing urbanisation in Hanoi, Vietnam recruited PWLD-caregiver dyads with multistage sampling. We utilised the Camberwell Assessment of Need for the Elderly (CANE) instrument to evaluate care needs across four domains. Caregivers rated PLWD needs, with higher scores indicating greater unmet needs. The Mann-Whitney test was employed for comparing two groups, while the Kruskal-Wallis test was used for comparisons involving more than two groups in the analysis, and a P-value of less than 0.05 was considered statistically significant. RESULTS: Among 90 PLWD participating in the study, the overall mean care needs score was 11.6 ± 4.3, with only 16.2% of PLWD having their care needs met. Environmental and physical needs were more frequently met than psychological or social needs. Only 48.0% and 43.9% of environmental and physical needs were met respectively, and a meagre 20.9% and 23.6% for psychological and social needs. Unmet care needs were more frequent for PWLD who were female, single or divorced, had lower monthly household income, or who were in more advanced stages of dementia, as indicated by Clinical Dementia Rating scores ≥1. CONCLUSIONS: Unmet needs for PWLD are common. Increased caregiver education, resources, and services in Vietnam are urgently required to improve the quality of life for this population.

Case report: PICC line for a toddler with bilateral bidirectional Glenn shunt, Fontan circulation, and persistent left superior vena cava.

Performing peripherally inserted central catheters for children with bilateral bidirectional Glenn shunt, Fontan circulation, and persistent left superior vena cava differs from those with normal central venous anatomy. This study presents two PICC procedures for a toddler with this condition to demonstrate an accurate PICC approach for such children.

Changes in Adolescents' Psychosocial Functioning and Well-Being as a Consequence of Long-Term COVID-19 Restrictions.

This work studied self-reports from adolescents on how the COVID-19 pandemic has changed their behaviors, relationships, mood, and victimization. Data collection was conducted between September 2020 and February 2021 in five countries (Sweden, the USA, Serbia, Morocco, and Vietnam). In total, 5114 high school students (aged 15 to 19 years, 61.8% females) responded to our electronic survey. A substantial proportion of students reported decreased time being outside (41.7%), meeting friends in real life (59.4%), and school performance (30.7%), while reporting increased time to do things they did not have time for before (49.3%) and using social media to stay connected (44.9%). One third of the adolescents increased exercise and felt that they have more control over their life. Only a small proportion of adolescents reported substance use, norm-breaking behaviors, or victimization. The overall COVID-19 impact on adolescent life was gender-specific: we found a stronger negative impact on female students. The results indicated that the majority of adolescents could adapt to the dramatic changes in their environment. However, healthcare institutions, municipalities, schools, and social services could benefit from the findings of this study in their work to meet the needs of those young people who signaled worsened psychosocial functioning, increased stress, and victimization.

Factors Associated With the Intention to Participate in Coronavirus Disease 2019 Frontline Prevention Activities Among Nursing Students in Vietnam: An Application of the Theory of Planned Behavior.

Introduction: Medical students have been serving as a key part of the frontline health workforce responding to the coronavirus disease 2019 (COVID-19) pandemic globally. Their contribution is especially important in the resource-scarce settings of developing nations such as Vietnam. Yet, the intention of medical students, in particular, nursing students, to participate in COVID-19 frontline prevention activities has not been well-understood. This study aimed to examine factors associated with the intentionto participate in COVID-19 frontline prevention activities among Vietnamese nursing students. Methods: A cross-sectional study was conducted on a total of 597 students in December 2020 in Hanoi, Vietnam. Information regarding the socioeconomic characteristics of participants, their source of COVID-19 related knowledge, and their perception and attitude toward participating in COVID-19 frontline activities [based on Theory of Planned Behavior (TPB)] was collected. A hierarchical regression model was employed to examine the association between intentions of students and associated factors. Results: A positive intention to participate in COVID-19 frontline prevention activities was found (mean score of 25.3 over 35; SD = 4.4; min = 5; max = 35). Attitude toward behavior, subjective norms, and perceived behavioral control (PBC) was found to be significantly associated with the intention of students. These variables explained the 37% variation in the intention of students in the model. Among three factors, subjective norm showed the strongest correlation with intention of students (ß = 0.358; p < 0.001). Obtaining information from official sources and community was also found to be positively correlated with intention to participate. Conclusion: Most of the respondents reported a positive intention to participate in COVID-19 frontline prevention activities. The findings suggested that the TPB was a good instrument to predict the intention to perform behavior among Vietnamese students. Enhancing the positive attitude of students, encouraging family and community supports, and providing adequately essential resources will contribute to optimizing the participation of students to confront COVID-19.

An External Validation Study of the Oakland and Glasgow-Blatchford Scores for Predicting Adverse Outcomes of Acute Lower Gastrointestinal Bleeding in an Asian Population.

AIMS: This study is aimed at (1) validating the performance of Oakland and Glasgow-Blatchford (GBS) scores and (2) comparing these scores with the SALGIB score in predicting adverse outcomes of acute lower gastrointestinal bleeding (ALGIB) in a Vietnamese population. METHODS: A multicenter cohort study was conducted on ALGIB patients admitted to seven hospitals across Vietnam. The adverse outcomes of ALGIB consisted of blood transfusion; endoscopic, radiologic, or surgical interventions; severe bleeding; and in-hospital death. The Oakland and GBS scores were calculated, and their performance was compared with that of SALGIB, a locally developed prediction score for adverse outcomes of ALGIB in Vietnamese, based on the data at admission. The accuracy of these scores was measured using the area under the receiver operating characteristic curve (AUC) and compared by the chi-squared test. RESULTS: There were 414 patients with a median age of 60 (48-71). The rates of blood transfusion, hemostatic intervention, severe bleeding, and in-hospital death were 26.8%, 15.2%, 16.4, and 1.4%, respectively. The SALGIB score had comparable performance with the Oakland score (AUC: 0.81 and 0.81, respectively; p = 0.631) and outperformed the GBS score (AUC: 0.81 and 0.76, respectively; p = 0.002) for predicting the presence of any adverse outcomes of ALGIB. All of the three scores had acceptable and comparable performance for in-hospital death but poor performance for hemostatic intervention. The Oakland score had the best performance for predicting severe bleeding. CONCLUSIONS: The Oakland and SALGIB scores had excellent and comparable performance and outperformed the GBS score for predicting adverse outcomes of ALGIB in Vietnamese.

Development and Validation of a Scoring System to Predict Severe Acute Lower Gastrointestinal Bleeding in Vietnamese.

BACKGROUND/AIMS: The prevalence of acute lower gastrointestinal bleeding (ALGIB) has progressively increased worldwide but there are few studies in Asian populations. This study aimed to develop and validate a scoring system to predict severe ALGIB in Vietnamese. METHODS: Risk factors for severe ALGIB were identified by multiple logistic regression analysis using data from a retrospective cohort of 357 patients admitted to a tertiary hospital. These factors were weighted to develop the severe acute lower gastrointestinal bleeding (SALGIB) score to predict severe ALGIB. The performance of SALGIB was validated in a prospective cohort of 324 patients admitted to 6 other hospitals using area under the receiver operating characteristics curve (AUC) analysis. RESULTS: There were four factors at admission independently associated with severe ALGIB in the derivation cohort: heart rate ≥ 100/min, systolic blood pressure < 100 mmHg, hematocrit < 35%, and platelets ≤ 150 × 103/µL. The SALGIB score determined severe ALGIB with AUC values of 0.91 and 0.86 in the derivation and validation cohorts, respectively. A SALGIB score < 2 associated with low risk of severe ALGIB in both cohorts (3.7% and 1.2%; respectively). CONCLUSIONS: The SALGIB score has good performance in discriminating risk of severe ALGIB in Vietnamese.

Excessive radon-based radiation in indoor air caused by soil building materials in traditional homes on Dong Van karst plateau, northern Vietnam.

Radon-based radiation from natural soil building materials is an important factor likely influencing residents' health as a contributing source of natural radiation. This survey aims to quantify the nuclide-specific α-radiation of isotopes 222Rn and 220Rn in common types of houses in a region of northern Vietnam, Dong Van karst plateau, to preliminarily (i) evaluate the total annual effective dose rates and (ii) assess the relative risk of cancer induction from indoor α-radiation for inhabitants. The average 222Rn concentrations in all house types were lower than 100 Bq m-3, but 220Rn abundances were far higher than 222Rn, even up to >1000 Bq m-3 in air close to a wall of unfired-soil bricks. The estimated total annual effective dose rates from indoor 222Rn and 220Rn and their progenies to residents with daily exposure of 13 h in the various types of houses range from 3.1 to 4.3 mSv a-1 for houses constructed with modified materials, but up to higher than 6 mSv a-1 in houses with raw building materials. The average risk of developing lung cancer as a consequence of a lifetime exposure to indoor α-radiation in affected homes ranges from 3.9% to 14.6%. 220Rn and its metallic progenies contribute more than 80% of the total average lung cancer risk from total radon, being responsible for a range of 2.7-14.6% of the risk of developing lung cancer.

Psychometric evaluation of the culturally and linguistically translated Vietnamese chronic kidney disease self-management instrument.

AIMS: To translate and psychometrically test the modified chronic kidney disease self-management instrument in Vietnamese language. BACKGROUND: Research on chronic kidney disease self-management is increasing although few patient-reported outcome measures are available in other languages. DESIGN: This study involved instrument modification, translation, and cultural adaptation into Vietnamese followed by psychometric evaluation in a target population. METHODS: Following modification, the instrument was translated by bilingual independent translators, and then an expert panel assessed content face validity. Reliability of the instrument was assessed by internal consistency and test-retest reliability in a sample of 293 people with chronic kidney disease. Then exploratory factor analysis was used to evaluate construct validity of the Vietnamese version. RESULTS: The Vietnamese chronic kidney disease self-management instrument demonstrated excellent content face validity and internal consistency. The test-retest indicated good stability of the instrument over a 2-week period. Four factors were identified using exploratory factor analysis and were named understanding my kidney disease, taking action to manage my kidney disease, seeking social support, and adhering to a healthy diet. CONCLUSIONS: The translated and modified version is a valid, reliable, and feasible patient-reported outcome measure of self-management behaviour in Vietnamese-speaking populations.

Effectiveness of self-management programme in people with chronic kidney disease: A pragmatic randomized controlled trial.

AIMS: To examine the effectiveness of a self-management intervention compared with usual care in adults with chronic kidney disease (CKD) on self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure. DESIGN: A parallel group randomized controlled trial. METHODS: Patients aged ≥ 18 years with CKD stages 3-5 were recruited between November 2015 and June 2016. Participants were randomly allocated into either the intervention (N = 68) or control group (N = 67). The control group received usual care, while the intervention group received usual care plus a self-management programme from a nurse. The intervention was guided by social cognitive theory (SCT) and included a face-to-face educational session followed by telephone support. Both groups were followed for 16 weeks. RESULTS: There were no significant differences in self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure between the two groups at baseline. At week 16, compared with the control group, large effect sizes for improved self-management, knowledge, and self-efficacy were detected. For health-related quality of life, the physical and mental health components significantly improved. However, no significant differences in either systolic or diastolic blood pressures were found. CONCLUSION: In earlier stages of CKD, a simple self-management education benefits patients. IMPACT: Effective self-management in the earlier stages of CKD contributes to slowing its progression, improving health outcomes and lowering the burden on healthcare systems. This study demonstrated that SCT increases CKD self-management by strengthening knowledge and self-efficacy. Nurses can give this education.

p38MAPK builds a hyaluronan cancer niche to drive lung tumorigenesis.

Expansion of neoplastic lesions generates the initial signal that instigates the creation of a tumor niche. Nontransformed cell types within the microenvironment continuously coevolve with tumor cells to promote tumorigenesis. Here, we identify p38MAPK as a key component of human lung cancer, and specifically stromal interactomes, which provides an early, protumorigenic signal in the tissue microenvironment. We found that lung cancer growth depends on short-distance cues produced by the cancer niche in a p38-dependent manner. We identified fibroblast-specific hyaluronan synthesis at the center of p38-driven tumorigenesis, which regulates early stromal fibroblast activation, the conversion to carcinoma-associated fibroblasts (CAFs), and cancer cell proliferation. Systemic down-regulation of p38MAPK signaling in a knock-in model with substitution of activating Tyr182 to phenylalanine or conditional ablation of p38 in fibroblasts has a significant tumor-suppressive effect on K-ras lung tumorigenesis. Furthermore, both Kras-driven mouse lung tumors and orthotopically grown primary human lung cancers show a significant sensitivity to both a chemical p38 inhibitor and an over-the-counter inhibitor of hyaluronan synthesis. We propose that p38MAPK-hyaluronan-dependent reprogramming of the tumor microenvironment plays a critical role in driving lung tumorigenesis, while blocking this process could have far-reaching therapeutic implications.
