Purpose This study aims to ascertain the impact of data collecting awareness on perceived information security concerns and information-sharing behavior on social networking sites. Design/methodology/approach Based on communication privacy management theory, the study forecasted the relationship between information-sharing behavior and awareness of data collecting purposes, data collection tactics and perceived security risk using structural equation modeling analysis and one-way ANOVA. The sample size of 521 young social media users in Vietnam, ages 18 to 34, was made up of 26.7% men and 73.3% women. When constructing the questionnaire survey method with lone source respondents, the individual’s unique awareness and experiences with using online social networks (OSNs) were taken into account. Findings The results of the investigation demonstrate a significant relationship between information-sharing and awareness of data collecting, perceptions of information security threats and behavior. Social media users have used OSN privacy settings and paid attention to the sharing restriction because they are concerned about data harvesting. Research limitations/implications This study was conducted among young Vietnamese social media users, reflecting specific characteristics prevalent in the Vietnamese environment, and hence may be invalid in other nations’ circumstances. Practical implications Social media platform providers should improve user connectivity by implementing transparent privacy policies that allow users to choose how their data are used; have clear privacy statements and specific policies governing the use of social media users’ data that respect users’ consent to use their data; and thoroughly communicate how they collect and use user data while promptly detecting any potential vulnerabilities within their systems. Originality/value The authors ascertain that the material presented in this manuscript will not infringe upon any statutory copyright and that the manuscript will not be submitted elsewhere while under Journal of Information, Communication and Ethics in Society review.

Chronic granulomatous disease (CGD) is an inborn error of immunity (IEI) disorder that results from defects in the respiratory burst activity in phagocytes, leading to the inability to kill bacterial and fungal microorganisms. CGD patients usually have a high incidence of morbidity such as infections and autoinflammatory diseases and a high mortality rate. Allogeneic bone marrow transplantation (BMT) is the only definitive cure for patients who suffer from CGD. We report the first transplant case of chronic granulomatous disease in Vietnam. A 25-month-old boy with X-linked CGD underwent bone marrow transplantation from his 5-year-old, full-matched human leukocyte antigen (HLA)-carrier sibling after myeloablative conditioning regimen with busulfan 5.1 mg/kg/day for 4 days, fludarabine 30 mg/m /day for 5 days, and rATG (Grafalon-Fresenius) 10 mg/kg/day for 4 days. Neutrophil was engrafted on day 13 posttransplant, donor chimerism was 100% on day 30 with the dihydrorhodamine-1,2,3 (DHR 123) flow cytometric assay test that reached 38% of the normal 45 days posttransplant. Five months after transplant, the patient was free of infection with stable DHR 123 assay at 37%, and donor chimerism remained 100%. No sign of a graft-versus-host disease had been observed posttransplant. We suggest that bone marrow transplantation is a safe and effectual cure for CGD patients, especially for patients with HLA-identical siblings.

The X-linked hyper IgM syndrome is a primary immunodeficiency disorder (PID) due to mutations in the CD40LG gene. Hyper IgM syndrome is characterized by the absence or decreased levels of IgG and IgA and normal or elevated IgM levels in serum. Affected patients become susceptible to infections such as pneumonia, diarrhea, and skin ulcer types. Hematopoietic stem cell transplantation is the only treatment currently available and ideally performed before the age of 10 years. Early, accurate diagnosis will contribute to the effective treatment for patients with hyper IgM. The patients from different Vietnamese families who have been diagnosed with hyper IgM at The Allergy, Immunology and Rheumatology Department, Vietnam National Hospital Pediatrics, were performed a genetic analysis using whole exome sequencing. The mutations were confirmed by the Sanger sequencing method in patients and their families. The influence of the mutations was predicted with the in silico analysis tools: PROVEAN, SIFT, PolyPhen-2, and MutationTaster. In this study, two novel mutations (p.Thr254fs and p.Leu138Phe) in the CD40LG gene were found in Vietnamese patients with X-linked hyper IgM syndrome. Our results contribute to the general understanding of the etiology of the disease and can help diagnose the different forms of PID.

BackgroundAs a first-line therapeutic option for multisystem inflammatory syndrome in children (MIS-C) with surging demand, intravenous immunoglobulin (IVIG) is associated with escalating costs and supply shortages, particularly in low-income and middle-income countries. This study compares the effectiveness of methylprednisolone alone versus IVIG combined with methylprednisolone for managing MIS-C.MethodsWe conducted a retrospective cohort study from January 2022 to June 2023 at Vietnam National Children’s Hospital. We used propensity score matching to compare the short-term outcomes based on immunomodulatory therapy with methylprednisolone alone or IVIG plus methylprednisolone.ResultsWe included 391 patients, comprising 255 boys and 136 girls, who fulfilled the MIS-C case definition of the US Centers for Disease Control and Prevention. Most patients (80.8%) received intravenous methylprednisolone monotherapy, and 19.2% were administered IVIG in addition to methylprednisolone. In general, the laboratory values indicative of hyperinflammatory and hyperthrombotic states displayed significant early response within 2–3 days after initial treatment, including white cell count (SE=1.77, p<0.001), NEU (SE=0.76, p=0.03), C reactive protein (SE=−46.51, p<0.001), PLT (SE=38.05, p=0.002), fibrinogen (SE=−0.37, p=0.002), d-dimer (SE=−849.8, p=0.02)); while subsequent improvement in cardiac markers was also observed, with pro-B-type natriuretic peptide (SE=−165.2, p<0.001) on day 5 and troponin I (SE=−0.05, p=0.004) on day 7. After propensity score weighting, there were 41 patients in each treatment group. Notably, there were no significant differences in the incidence of cardiac events between treatment groups regarding left ventricular dysfunction and coronary artery dilation or aneurysms (10.3% vs 20.7%, p=0.074 and 63.4% vs 56.1%, p=0.653, respectively). While the median paediatric intensive care unit length of stay (LOS) and hospital LOS were slightly lengthier in the IVIG and methylprednisolone group compared with those of the methylprednisolone group, these differences were not statistically significant ((5 vs 4, p=0.782) and (9 vs 7, p=0.725), respectively).ConclusionsInitial treatment with methylprednisolone monotherapy appears not inferior in effectiveness to adjunctive IVIG plus methylprednisolone in MIS-C. Further investigations in randomised controlled trials deserve to be undergone to clarify if IVIG-sparing glucocorticoids are a viable option for achieving favourable outcomes in MIS-C, particularly in resource-limited settings with barriers approaching IVIG therapy.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome and Stevens-Johnson Syndrome (SJS) are severe cutaneous adverse reactions to drugs. Those reactions which are rare in children can be especially severe and challenging to diagnose and manage. Herein we present a 59-month-old male who presented with a rash, fever, and multiple organ dysfunction initiation of Phenobarbital for epilepsy. Diagnosis of ovelaping SJS and DRESS syndrome had been made based on clinical manifestations accompanied with skin biopsy according to RegisSCAR diagnostic criteria. A therapy with intravenous immune globulin (IVIG), corticosteroids and supportive care was given successfully for the patient. This case underscored the significance of promptly and effectively recognizing and managing these intricate reactions.

The serum level of soluble (s)E-cadherin is elevated in several malignancies, including prostate cancer (PCa). This study was designed to investigate the effects of sE-cadherin on the behavior of PCa cells in vitro, with the aim of identifying a potential therapeutic target. Growth as well as adhesive and motile behavior were evaluated in PC3, DU-145, and LNCaP cells. Flow cytometry was used to assess cell cycle phases and the surface expression of CD44 variants as well as α and β integrins. Confocal microscopy was utilized to visualize the distribution of CD44 variants within the cells. Western blot was applied to investigate expression of α3 and β1 integrins as well as cytoskeletal and adhesion proteins. Cell growth was significantly inhibited after exposure to 5 µg/mL sE-cadherin and was accompanied by a G0/G1-phase arrest. Adhesion of cells to collagen and fibronectin was mitigated, while motility was augmented. CD44v4, v5, and v7 expression was elevated while α3 and β1 integrins were attenuated. Blocking integrin α3 reduced cell growth and adhesion to collagen but increased motility. sE-cadherin therefore appears to foster invasive tumor cell behavior, and targeting it might serve as a novel and innovative concept to treat advanced PCa.

Objective This study aimed to compare adverse in-hospital outcomes in ileal conduit versus neobladder urinary diversion type after radical cystectomy (RC) in contemporary versus historical patients. Methods Patients were identified within the National Inpatient Sample (NIS 2000–2019). Propensity score matching (PSM; 1:2 ratio) and multivariable logistic regression models (LRMs) were used. Results Of 10,533 contemporary (2011–2019) patients, 943 (9.0%) underwent neobladder urinary diversion, while 9590 (91.0%) underwent ileal conduit urinary diversion. Furthermore, of 9742 historical (2010–2019) patients, 932 (9.6%) underwent neobladder urinary diversion and 8810 (90.4%) underwent ileal conduit urinary diversion. After 1:2 PSM, within the contemporary cohort, 943/943 (100%) neobladder versus 1886/9590 (19.6%) ileal conduit patients were included. Similarly, within the historical cohort, 932/932 (100%) neobladder versus 1864/8810 (21.1%) ileal conduit patients were included after PSM. In multivariable LRMs, relative to contemporary neobladder patients, contemporary ileal conduit patients exhibited higher rates of overall postoperative (49.0 vs. 43.6%; multivariable odds ratio [MOR] 1.2), wound (4.2 vs. 2.7%; MOR 1.6), and genitourinary (13.1% vs. 10.0%; MOR 1.3) complications as well as blood transfusions (19.0 vs. 15.6%; MOR 1.3). Conversely, in multivariable LRMs within the historical cohort, no differences were recorded between ileal conduit and neobladder patients. Conclusions Unlike historical comparisons between ileal conduit and neobladder patients, where no differences in adverse in-hospital outcomes were recorded, analyses relying on a contemporary patient cohort subject to PSM and multivariable adjustment revealed higher rates of adverse in-hospital outcomes in 4/13 examined categories. This observation should be considered at informed consent.

Awareness of inborn error immunity, such as Wiskott-Aldrich syndrome (WAS), is still lacking in Vietnam. The shortage of clinical immunologists and transplantation teams lead to poor prognosis for patients. Describe initial data about hematopoietic stem cell transplantation (HSCT) for WAS. Retrospective analyzing 15 procedures on 13 patients at the Vietnam National Children's Hospital from 2020 to 2024. The median age at HSCT was 34 months (range: 17-86). Of the patients, 73.3% received myeloablative conditioning based on busulfan, while 26.7% underwent reduced-intensity conditioning. Donor sources included matched sibling donors (MSD, 20.0%), unrelated cord blood (UCB, 33.3%), phenotypically identical family donor (MFD, 6.7%), and mismatched related donors (MMRD, 40.0%). The median stem cell dose was 4.9 × 10^6/kg of the recipient's body weight (range: 0.33 to 10.4 × 10^6/kg). Neutrophil and platelet engraftment occurred at a median of 14 days (range: 10-19) and 48 days (range: 14-143), respectively. By day +30, 73.3% of patients achieved full donor chimerism. One patient experienced graft failure, and another faced graft rejection two months post-transplant, both of whom underwent a second transplant with different donors. The overall survival rate was 92.3% with a median follow-up of 23 months (range: 6-53), with one patient died from chronic graft-versus-host disease (cGVHD). All surviving patients achieved normalization of platelet counts. HSCT offers significant benefits to WAS patients, achieving an excellent overall survival rate.
