Workplace violence against medical students during clinical practice and its relevant factors: a mixed methods study.

Our study aims to describe the status of workplace violence against medical students during clinical practice, which consists of its prevalence, types, perpetrators, students' responses and influences on them, reasons for workplace violence and to determine some relevant factors of this issue through both quantitative questionnaire and qualitative interview. A descriptive cross-sectional study with mixed methods was conducted on 320 students from the second-year to the sixth-year classes at Hanoi Medical University from August 2022 to February 2023. The questionnaire was based on the WHO questionnaire survey 'Workplace violence in the health sector - country case studies research instruments - Geneva 2003'.

Three-Tesla Magnetic Resonance Imaging Characteristics of Hypertrophic Cardiomyopathy: A Comparison with Several Echocardiography Parameters.

Background: Hypertrophic cardiomyopathy (HCM) is a primary cardiac disorder characterized by myocardial hypertrophy without increased afterload. This study set out to describe the cardiac magnetic resonance (CMR) imaging characteristics of HCM and to evaluate correlations of selected CMR parameters with echocardiography.

Methods: This cross-sectional study enrolled 46 patients diagnosed at the Vietnam Heart Institute with HCM and underwent CMR at the Radiology Center, Bach Mai Hospital, from July 2021 to September 2022.

Aortic Balloon Occlusion in Repair of Ruptured Abdominal Aortic Aneurysm.

This case report details a novel technique implemented in Vietnam. When full equipment is unavailable, we adapt it by using aortic balloon occlusion to enhance the patient's hemodynamics and mitigate the risk of intraprocedural exsanguination. This approach effectively addresses the rupture of abdominal aortic aneurysms in patients with unstable hemodynamic conditions.

Role of β-blockers in the cardiovascular disease continuum: a collaborative Delphi survey-based consensus from Asia-Pacific.

Objective: This Delphi method of consensus was designed to develop scientific statements for β-blockers in the continuum of cardiovascular diseases with a special focus on the role of bisoprolol.

Methods: Eleven experienced cardiologists from across the Asia-Pacific countries participated in two rounds of the survey. In the first round, experts were asked to rate agreement/disagreement with 35 statements across seven domains regarding the use of β-blockers for treating hypertension, heart failure, coronary artery diseases, co-morbidities, as well as their safety profile, usage pattern, and pharmacokinetic variability.

Prevalence and Factors Associated with Atrial Fibrillation in Patients with Transient Ischemic Attack or Ischemic Stroke in Northern Vietnam.

Background: The prevalence and risk factors of atrial fibrillation (AF) in patients with transient ischemic attack (TIA) or ischemic stroke in Northern Vietnam are not well understood. This study aimed to estimate the prevalence and identify factors associated with AF in this population.

Methods: A cross-sectional study was conducted on 2038 consecutive patients with TIA or ischemic stroke admitted to Bach Mai Hospital.

Adherence to hypertension and dyslipidemia treatment and its implication on control of cardiovascular disease in Vietnam: A semi-systematic review.

Background: To understand the prevalent issues and challenges in the provision of care for dyslipidemia and hypertension in Vietnamese adults, quantification of patient journey stages (awareness, screening, diagnosis, treatment, adherence, and control) was performed in this semi-systematic review.

Methods: The EMBASE and MEDLINE databases were searched for English articles published between 2010 and 2019. Thesis abstracts, letters to the editor, editorials, case studies, and studies on patient subgroups or nationally unrepresentative studies, were excluded.

A complex genomic rearrangement involving the endothelin 3 locus causes dermal hyperpigmentation in the chicken.

Dermal hyperpigmentation or Fibromelanosis (FM) is one of the few examples of skin pigmentation phenotypes in the chicken, where most other pigmentation variants influence feather color and patterning. The Silkie chicken is the most widespread and well-studied breed displaying this phenotype. The presence of the dominant FM allele results in extensive pigmentation of the dermal layer of skin and the majority of internal connective tissue.

Radioprotective effects of vitexina for breast cancer patients undergoing radiotherapy with cobalt-60.

Vitexina, a product containing the flavonoid vitexin as the main component, is derived from a plant, Vigna radiata (L.), that has been traditionally used in Vietnam for detoxification. This remedy is also used to treat the symptoms of conditions classified as "hot" in traditional medicine.

LAI reactivity in rats immunized with tumor cells.

Leukocytes of peripheral blood of F1 hybrid inbred strain of rats LW X AVN and rats of inbred Lewis strain, immunized for three consecutive weeks with increasing doses of live or dead MC-1 or B 77 tumor cells, incubated for 20 hours with specific tumor extract, showed a lower adhering ability (LAI 32.8 +/- 16.6, 44.

Comparison of LAI reactivity in B 77 tumor bearing rats between, before and after surgical removal of tumors.

Using a new modification of the tube LAI test, LAI reactivity was followed in rats of the inbred Lewis (LW) strain with transplanted syngeneic B 77 tumors before and one month after a surgical removal of the tumors. A significant decline in LAI reactivity was noted after a thorough extirpation of the tumors as compared to that prior to the surgical intervention. The results have been compared and are here discussed with a view to a possible application of the LAI test in studies of antitumor immunity in patients with a malignant disease.

Detection of specific immunoreactivity by LAI assay in patients with malignant melanoma of uveal tissue.

To monitor the specific antitumor immunity to patients with malignant melanoma of the uveal tissue, use was made of the 20-hr modification of the leukocyte adherence inhibition (LAI) test. Simultaneously, changes in the proportionally of T (total and active) and B lymphocytes in peripheral blood were followed in the same patients by the E and EAC rosette formation test. Peripheral blood leukocytes from patients with malignant melanoma of the uvea, cultured in vitro for 20 hr with syngeneic and allogeneic tumor extract showed a significantly lower adhering capacity than the same cell population cultured without the specific tumor extract (21/22).

Blocking factor in sera of MC1 and B77 tumor bearing rats detected by LAI assay.

A modified form of the leukocyte adherence inhibition assay (LAI assay) has been used to detect the blocking factor in serum of the Lewis (LW) inbred rats and the F1 hybrids of the inbred LW X AVN strains with transplantated syngeneic B77 and MC1 tumors. This study has indicated that the cell mediated antitumor immune response of rats immunized with living tumor cells and the blocking factor in serum of rats with progressively growing tumors may be demonstrated by the LAI assay with incubation time prolonged to 20 hr (LAI assay-IT20). In addition, the specificity of the blocking effect and the disappearance of blocking factor after surgical removal of tumors have also been demonstrated in this paper.

Peripheral blood lymphocytes and EAC-rosette forming cells in B77 tumor bearing rats.

The percentage and absolute numbers of peripheral blood lymphocytes and EAC-rosette forming cells were evaluated in B77 tumor bearing rats. The peripheral blood lymphocytes were in high level even in rats bearing very small tumors; this result suggest the mobilization of lymphoyctes into peripheral blood in tumor bearing rats. The increase of EAC-rosette forming cells was accompanied with the growth of tumors.
