Accuracy of estimated glomerular filtration rate equations in potential Vietnamese living kidney donors
Background: The accurate assessment of the glomerular filtration rate (GFR) in potential living kidney donors (PLKDs) is essential for successful transplantation and safeguarding
kidney donation practice. Scintigraphy-measured GFR (mGFR) is widely regarded as the clinical reference standard. Various estimated GFR (eGFR) equations, such as the Modification of
Diet in Renal Disease (MDRD), Cockcroft–Gault (CG), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations, have been developed; however, none have been specifically validated for Vietnamese PLKDs. This study aimed to evaluate the accuracy of eGFR formulas compared to mGFR in PLKDs. Methods: This convenience retrospective study analyzed
189 PLKDs at Cho Ray Hospital in Vietnam from January 2014 to December 2020. The eGFR
was calculated using various formulas and compared to the mGFR assessed using 99mTechnetiumdiethylenetriaminepentaacetic acid. Bias, accuracy, and Bland–Altman plots were used to assess the
significance of the eGFR values. Results: The median mGFR was 94.20 mL/min/1.73 m2
(interquartile
range [IQR]: 88.40–100.50). The eGFR values were as follows: 77.52 mL/min/1.73 m2
(IQR: 70.50–86.33)
for CG; 76.14 mL/min/1.73 m2
(IQR: 68.05–83.37) for MDRD; 106.80 ± 15.24 mL/min/1.73 m2
for
CKD-EPI cystatin C 2012; 96.44 ± 13.40 mL/min/1.73 m2
for CKD-EPI creatinine cystatin C 2012;
88.74 ± 13.27 mL/min/1.73 m2
for CKD-EPI creatinine 2021; and 101.32 ± 12.82 mL/min/1.73 m2
for
CKD-EPI creatinine cystatin C 2021. Among these formulas, the CKD-EPI creatinine cystatin C 2012
(P30 = 98.96%) and 2021 (P30 = 97.92%) showed the best consistency with the mGFR, owing to their
high accuracy, low bias, and narrow limits of agreement in the Bland–Altman plots. Conclusions:
The CKD-EPI equations based on creatinine and cystatin C are reliable tools for donor screening.

Factors associated with the prolonged use of donor human milk at the Da Nang hospital for women and children in Vietnam
Background and Objectives: Donor human milk (DHM) from a human milk bank (HMB) is
used to feed low-birthweight (LBW) and preterm infants when mothers cannot provide their own
breastmilk. The misuse of DHM could interfere with mothers’ breastmilk and weaken breastfeeding
efforts. This study aimed to identify factors behind prolonged DHM usage during the first six
years of Vietnam’s first HMB. Methods: Data were extracted from the Da Nang HMB’s digital
monitoring system. We defined prolonged DHM use as four or more days in the neonatal unit and
two or more days in postnatal wards. Results: Over six years, 25,420 infants received DHM, with
45.3% of the infants being female, 54.7% being male, 70.0% being born via cesarean section, and
77.2% being full-term. In the neonatal unit (n = 7001), 38.0% of infants used DHM for ≥4 days.
Adjusted odds ratios (aORs) for prolonged use were 0.14 for infants weighing <1000 g, 0.78 for infants
weighing 1000–<1500 g, and 0.67 for infants weighing ≥2000 g (p < 0.01), compared to those weighing
1500–<2000 g. Compared to gestational ages of 32–<34 weeks, the aORs were 0.26 for <28 weeks,
0.71 for 34–<37 weeks, and 0.35 for ≥37 weeks (p < 0.01). In postnatal wards (n = 18,419), 53.1% of
infants used DHM for ≥2 days. Compared to term, normal-weight infants, the aORs were 1.25 for
LBW–preterm, 1.17 for LBW–term, and 1.21 for normal-weight–preterm infants (p < 0.05). Prolonged
DHM use was associated with cesarean births in neonatal units (aOR 2.24, p < 0.01) and postnatal
wards (aOR 1.44, p < 0.01). Conclusions: DHM is used briefly to bridge nutritional gaps and transition
to mothers’ breastmilk, but LBW, preterm births, and cesarean births are linked to prolonged use.
Healthcare providers should support those at risk of prolonged DHM use and prioritize reducing
unnecessary cesarean births.

Impact of university reputation and academic quality on university selection among Vietnamese postgraduate students: A moderation analysis of gender
This study investigated the phases involved in postgraduates’ decision-making
process when selecting a university in Vietnam. By analyzing the key factors that influence these decisions, the research provides insights into how these elements impact
students’ university choices, offering a deeper understanding of enrolment behavior in
the Vietnamese educational context. The survey was conducted by gathering quantitative
data. With an emphasis on gender moderating university choice decisions, a 16-item
questionnaire was used to measure university reputation and academic quality. Utilizing a
quantitative approach, data were collected from a sample of postgraduate students and
analyzed using Structural Equation Modeling (SEM) via SmartPLS 4. The results reveal that
both university reputation and academic quality significantly influence university choice
decisions. However, the moderating effect of gender on these relationships was found to
be insignificant. These findings contribute to the limited literature on higher education
marketing in Vietnam, particularly concerning postgraduate students, and offer valuable
insights for university administrators. This study is in line with SDG 5 (Gender Equality),
which includes topics like gender parity, inclusive participation, and gender equity, and
SDG 4 (Quality Education), which highlights the significance of academic quality and
reputation when choosing a university

Influential factors on postgraduates’ satisfaction with the quality of pharmacy education: Evidence from a University in Vietnam
The study aimed to investigate the determinants of pharmacy postgraduates’
satisfaction to suggest essential recommendations to enhance educational quality at Hanoi
University of Pharmacy in Vietnam. A cross-sectional survey was conducted among
202 postgraduates using structured questionnaires, with 31 multidimensional questions
and 1 question addressing overall satisfaction. Cronbach’s alpha was used to evaluate
the questionnaire’s internal consistency, Exploratory Factor Analysis (EFA) identified key
factors, and multiple linear regression analysis was applied to assess the impact of these
factors. Overall satisfaction had a high mean score of 4.49 out of 5 (SD = 0.602). The
final 29 questions were retained and divided into four main factors affecting satisfaction
after rotating EFA. The dimension of “Support and Evaluation” was the most influential
factor (β = 0.475), followed by “Training Organization”, “Facilities and Library”, and
“Lecturers and Curriculum”. The variables with the lowest scores needed much more
attention, including digital systems (4.2, SD = 0.852), information technology support
(4.32, SD = 0.772), activities boosting lifelong learning skills (4.48, SD = 0.624), and the
reasonability of the education program’s structure (4.48, SD = 0.608) and the studying
program’s schedule (4.45, SD = 0.607). The findings indicate the issues that should be
addressed, and have highlighted that improvements in electronic library accessibility and
updated curricula are also recommended to further optimize the educational experience of
postgraduate students.

Post-occupancy evaluation in high-rise apartment buildings in Vietnam
As part of the CAMaRSEC research project, long-term indoor environmental
measurements with accompanying occupant surveys were conducted over one year in
49 households in 15 high-rise residential apartment buildings in Hanoi, Vietnam. A comprehensive analysis of the collected data revealed differences in the indoor environment
and energy consumption patterns during the operational phase of the buildings, as well as
their correlation with diverse occupant behaviors. In addition, by comparing subjective
thermal evaluations based on occupant surveys with predictions based on comfort models,
the limitations of existing models in predicting the thermal sensations of local people
were identified. Furthermore, the findings indicated that the apartment building design
standard in Vietnam underestimates the thermal adaptation of occupants, which may lead
to significant building performance gaps. Larger scale surveys and measurements are
required to provide sufficient databases to refine local building design standards, especially
for mixed-mode buildings

Revisiting the energy-saving behavior of hotel guests: An integrated model of TPB and NAM in Vietnam
This paper explores the energy-saving behavior of hotel guests in the Vietnamese
context. We adapted the theory of planned behavior (TPB) and the norm activation model
(NAM) to develop a research model with six determinants of energy-saving intention
and behavior. A self-administered online survey was implemented to collect data from
hotel guests in Hanoi and Quang Ninh provinces. After 4 months, we received 253 valid
responses for further analysis. SmartPLS 4.0 software was employed for structured equation
model testing. Our findings showed that TPB variables and NAM variables jointly explain
the energy-saving intention and energy-saving behavior of Vietnamese hotel guests. Among
the three factors of TPB, subjective norms have the most substantial impact on energysaving intention and a significant direct effect on energy-saving behavior. Meanwhile,
awareness of consequences does not significantly affect personal norms, and in turn,
personal norms do not directly affect energy-saving behavior. Thus, we proposed several
solutions to hotel managers to promote energy-saving initiatives and attract the engagement
of their guests in these initiatives.

The impact of vaccination on COVID-19 outcomes in Vietnam
Objectives: This study aimed to assess the effectiveness of the COVID-19 vaccine on the
outcomes of patients in three hospitals in Vietnam. Methods: An observational study involved
3102 confirmed COVID-19 patients from Vietnam. Participants were classified into unvaccinated,
partially vaccinated (one dose) (PV), fully vaccinated (two doses) (FV), and boosted (three doses)
groups. We used a regression model to assess the relationship between vaccine status and disease
outcome, including mortality, persistent symptoms after treatment, and hospital duration. Results:
The proportions of unvaccinated, PV, FV, and boosted groups were 43.39%, 4.63%, 43.93%, and
8.05%, respectively, and 48% of the participants had at least one comorbidity. The proportion of
severe clinical disease was significantly higher in the unvaccinated compared with the vaccinated.
Biomarkers of cellular injury and organ failure, e.g., aspartate aminotransferase (AST), ferritin, troponin T, proBNP, D-dimer, and urea plasma concentration were significantly higher in unvaccinated
and PV patients compared with FV and boosted patients. Age was the most crucial predictor of
critical illness, followed by vaccine status, hypertension, diabetes, heart disease, and chronic kidney
disease. The unvaccinated group had the highest proportion of deaths (5.2% vs. 1.4% and 0.3%
in FV and boosted groups, respectively). Conclusions: Vaccination reduced mortality and both
hospitalization length and disease severity in COVID-19 survivors, especially the older and patients
with chronic comorbidities.
