RESUMEN
There have been many studies on the adverse effects of coronavirus disease 2019 (COVID-19) vaccines but the urinary incontinence after COVID-19 vaccination is rare. Here, we report an 8-year-old boy presented to outpatient department, Thai Binh University of Medicine Hospital, Thai Binh, Vietnam with complaints of urinary incontinence for the past 2 weeks, following the first dose of the messenger RNA vaccine. He had no other abnormalities in clinical and laboratory exams. This clinical situation suggested vaccine side effects. No specific treatment was administered upon diagnosis without toilet and bladder training. Subsequent monitoring revealed a gradual reduction in symptoms over 2 months, with complete recovery achieved at the 14th week from the onset of symptoms, without necessitating any medical intervention. This case highlights the need for thorough evaluation and assessment of potential adverse effects following vaccination, including uncommon presentations.
RESUMEN
ObjectiveThis article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study, a systematic review, and a meta-analysis. MethodsThe study was conducted in three stages. In the first stage, subjects were recruited for health examination in four hospitals in Chengdu, Tianjin, Beijing, and Chongqing, China, from 2015 to 2020, and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center. In the second stage, Embase, PubMed, Wanfang Data, VIP, and CNKI databases were searched for related studies published up to May 2021, and a meta-analysis was conducted to further verify such association. In the third stage, the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature. ResultsA total of 633 948 participants were enrolled in the cross-sectional study, and the prevalence rate of GSD was 7.844%. The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P<0.05). Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes, ages, and subtypes of GSD. A total of 80 articles were included in the systematic review and the meta-analysis, and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure. ConclusionHypertension significantly increases the risk of GSD, and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.
RESUMEN
Exosome is a kind of extracellular vesicles secreted by cells to the outside. Biogenesis mainly involves two invaginations of the cytoplasmic membrane, the formation of multivesicular bodies, and the release of exosomes. Exosomes have abundant and diverse inclusions—including landmark membrane proteins, soluble proteins, various RNA molecules and DNA fragments, etc. Cells can achieve intercellular signal communication by secreting and receiving exosomes. Through interaction of ligand molecules on the exosome membrane with receptors on the surface of other cytoplasmic membranes, exosomes can activate cell signal transduction or fuse with the cell membrane to release its contents into the cytoplasm to exert regulatory functions. In the central nervous system, exosomes secreted by neurons and various glial cells can mediate wired synaptic signal transmission, but mainly play a role similar to neuromodulator by way of volume transmission. In this paper, the biogenesis of exosomes and important functional components are described in detail, and the characteristics of neural exosomes in the biogenesis, content sorting and controlled release are compared with those of synaptic vesicles. We further review the research progress on the physiological functions of neural exosomes on the central nervous system and their roles in the occurrence and development of neurodegenerative diseases and major depressive disorder. We also prospect the application of exosomes in the early diagnosis and targeted therapy of nervous system diseases.

@#Objective To explore the clinical and etiological features of rare and special thalamic artery(thalamotuberal artery,thalamoperforating artery,and posterior choroidal artery) occlusion. Methods We included 48 patients with thalamogeniculate artery occlusion and 19 patients with non-thalamogeniculate artery occlusion to compare their clinical manifestations and etiological classifications. Results Compared with the thalamogeniculate artery occlusion group,the non-thalamogeniculate artery occlusion group showed a significantly higher percentage of decline in advanced cognition(0.00% vs 21.1%, χ2=10.747,P=0.001),a significantly lower percentage of unilateral sensory disturbance(75% vs 21.1%, χ2=16.466,P<0.001),a significantly higher percentage of large artery atherosclerosis in etiology classification(29.17% vs 84.2%, χ2=16.679,P<0.001),and a significantly larger infarct volume(t=10.86,P<0.001). Conclusion Patients with thalamic stroke caused by non-thalamogeniculate artery occlusion are more likely to have decline in advanced cognition and large artery atherosclerosis. More attention should be paid to large vessel disease screening for such patients.
RESUMEN
Background: Risk communication is necessary to improve the booster vaccination rate, but Vietnam does not have a system to collect and disclose such information. Therefore, the purpose of this study was to clarify adverse reactions and their frequency in the early period after booster vaccination, and to obtain primary data for improving the booster vaccination rate. Methods: A cross-sectional survey was conducted among adults aged ≥18 years. Clinical data were collected 14 days after booster vaccination by using a standard questionnaire. Results: A total of 1322 participants were included with median age = 23 and sex ratio (Male/Female) = 0.53. AstraZeneca was the most commonly used vaccine for the first and second doses, while Pfizer was the most commonly used vaccine for booster shots. Injection site pain, fatigue, and myalgia were the most common side effect reported (71.9%, 28.1%, and 21.8%, respectively). Compared to previous COVID-19 vaccine injections, 81.9% of participants reported that their symptoms were similar or milder after receiving the booster dose. They were more likely to present injection site pain (OR = 1.43, p < 0.0001) and lymphadenopathy (OR = 4.76, p < 0.0001) after receiving the booster shot. Fever (OR = 0.33, p < 0.0001) and fatigue (OR = 0.77, p = 0.002) were less often reported after booster shots compared to the first and second injections. The severity of symptoms occurring after booster dose versus first and second doses increased significantly with each additional year of age and among participants receiving the Pfizer and Moderna vaccines. Conclusion: Adverse reactions to booster vaccination are minor and their incidence is the same as for the first or the second vaccination. Multicenter studies with larger sample sizes on the side effects and safety of COVID-19 vaccine booster shots need to be conducted to make the population less worried, in order to increase the vaccination rate, to protect individuals' and communities' health.
RESUMEN
@#To explore the correlation analysis between the changes of cognitive function and the expression levels of serum ICAM-1 and 8-iso-PGF2α in patients with acute ischemic stroke. Method A total of 100 patients with Acute ischemic stroke admitted to our hospital from August 2017 to October 2019 were divided into group A (60 cases,MoCA score<26 points) and group B (40 cases,MoCA) according to the MoCA score Score ≥26 points). Enzyme-linked immunosorbent assay was used to determine the expression levels of ICAM-1 and 8-iso-PGF2α in the two groups. Spearman was used to analyze the correlation between serum ICAM-1 and 8-iso-PGF2α and MoCA scores. Logistic regression was used to analyze Acute ischemic stroke. Influencing factors of patients’ cognitive function changes. ROC curve analysis of serum ICAM-1,8-iso-PGF2α expression for the diagnostic value of cognitive function in patients with Acute ischemic stroke. Results The expression of serum ICAM-1 and 8-iso-PGF2α in group A was significantly higher than that in group B (P<0.05);Serum ICAM-1 and 8-iso-PGF2α expression levels were significantly correlated with the location of infarct,carotid atherosclerosis,carotid stenosis,NIHSS score,MoCA,and age (P<0.05),but not related to education level (P> 0.05). The infarcts were located in the thalamus,temporal lobe and frontal lobe. NIHSS score,diabetes and hypertension were independent risk factors for cognitive dysfunction in patients with Acute ischemic stroke (P<0.05). The sensitivity and specificity of ICAM-1 and 8-iso-PGF2α in diagnosing the changes of cognitive function in patients with Acute ischemic stroke were 93.00% and 90.00% (P<0.05). Conclusion The expression of serum ICAM-1 and 8-iso-PGF2α is closely related to the changes of cognitive function in patients with Acute ischemic stroke.
RESUMEN
Bronchopulmonary dysplasia (BPD) is a chronic lung disease due to impaired pulmonary development and is one of the main causes of respiratory failure in preterm infants. Preterm infants with BPD have significantly higher complication and mortality rates than those without BPD. At present, comprehensive management is the main intervention method for BPD, including reasonable respiratory and circulatory support, appropriate enteral nutrition and parenteral nutrition, application of caffeine/glucocorticoids/surfactants, and out-of-hospital management after discharge. The continuous advances in stem cell medicine in recent years provide new ideas for the treatment of BPD. Various pre-clinical trials have confirmed that stem cell therapy can effectively prevent lung injury and promote lung growth and damage repair. This article performs a comprehensive analysis of the mechanism of mesenchymal stem cells in the treatment of BPD, so as to provide a basis for clinical applications.

BACKGROUND: Diabetes-related distress (DRD) refers to negative emotional and affective experiences from daily demands of living with diabetes. People who received social support seem less likely to experience DRD. The prevalence of T2D in Vietnam is rapidly increasing. Yet, DRD and its association with social support have not been investigated. This study investigates DRD and how it is associated with unmet needs for social support in people with T2D in Thai Binh Province, Vietnam. METHODS: A total of 806 people, age ≥ 40 years, treated for T2D at primary hospitals in Thai Binh Province, Vietnam, completed a questionnaire-based cross-sectional survey. DRD was self-reported, based on the Problem Areas In Diabetes scale 5 (PAID5). We assessed 6 types of unmet needs for social support from family/friends/community including: (i) Transport and company when visiting health facilities; (ii) Reminders to take medication; (iii) Purchase and preparation of food; (iv) Reminders to engage in physical exercise; (v) Emotional support; and (vi) Financial support. Multivariable logistic regression was used to model DRD as an outcome of each type of unmet need for social support, and as an outcome of the number of unmet needs for social support, adjusted for three sets of covariates. RESULTS: In this study, 50.0% of people with T2D experienced DRD. Odds for DRD were higher among those who had any unmet need for social support. After adjustment for household economic status, only unmet needs for emotional and financial support were associated with higher odds ratios of DRD (OR = 2.59, CI95%: 1.19-5.63 and OR = 1.63, CI95%: 1.10-2.40, respectively). People who had ≥2 type of unmet need were not a higher risk of experiencing DRD as compared to those with no unmet need. CONCLUSIONS: Half of the people with T2D experienced DRD. The results suggest that having enough finances may decrease most needs for social support with the exception of emotional support. Thus, social support to financial and emotional of diabetes aspects may contribute to prevent or reverse DRD.

OBJECTIVE@#To evaluate the effect of zoledronate acid (ZA) on the proliferation and osteogenic differentiation of rat mesenchymal stem cells (BMSCs).@*METHODS@#The BMSCs isolated from the SD rats were cultured with different concentrations of ZA (1, 5, 10, and 20 μmol·L), and the contro1 group received the same volume of culture medium but without ZA. Cell counting kit-8 was used to detect proliferation activity in each group. Alkaline phosphatase (ALP) staining and alizarin red staining were used to detect the osteogenic differentiation ability in each group. The gene expression levels of ALP, bone morphogenetic protein-2 (BMP-2), typeⅠcollagenase (COL-Ⅰ), runt-related transcription factor-2 (Runx-2), zinc finger structure transcription factor (Osx), osteocalcin (OCN), and osteopontin (OPN) were evaluated by real-time quantitative polymerase chain reaction (qRT-PCR).@*RESULTS@#Zoledronate at 1 μmol·L⁻¹ concentration had no effect on the proliferation and osteogenic differentiation of BMSCs. No significant difference was observed between this group and the control group (P>0.05). When the ZA concentration was more than 1 μmol·L⁻¹, ZA inhibited the proliferation and osteogenic differentiation of BMSCs, and the effect was concentration dependent. The difference between each group and the control group was statistically significant (P<0.05). At ZA concentration of 5 μmol·L⁻¹, ZA enhanced the expression of ALP, BMP-2, COL-Ⅰ, Runx-2, Osx, OCN, and OPN (P<0.05). However, at ZA concentration of more than 5 μmol·L⁻¹, the expression levels of osteogenicrelated genes in each group was lower than those of the control group (P<0.05).@*CONCLUSIONS@#Low ZA concentration has no effect on the proliferation and osteogenic differentiation of BMSCs. ZA at 5 μmol·L⁻¹ concentration inhibits the proliferation but promotes the osteogenic differentiation of BMSCs. High ZA concentration inhibits the proliferation and osteogenic differentiation of BMSCs.

<p><b>INTRODUCTION</b>Minimally invasive surgical ablation is an emerging alternative method to catheter ablation and the full surgical maze procedure for nonpharmacologic treatment of atrial fibrillation (AF). We present a totally thoracoscopic "box lesion" radiofrequency ablation procedure in patients with paroxysmal or persistent AF.</p><p><b>MATERIALS AND METHODS</b>From June 2011 to October 2012, 14 patients with lone paroxysmal (n = 7) or persistent AF (n = 7) were enrolled in this study. Procedures were performed through 3 5-12 mm holes on each side of the chest wall. A bipolar ablation device was used to create a box lesion in the posterior wall of the left atrium that encircled the 4 pulmonary veins (achieving bilateral pulmonary vein/posterior left atrial wall isolation). Perioperative complications were recorded for all patients. Freedom from AF was assessed by 24-hour Holter monitoring every 3 months or during symptoms of arrhythmia.</p><p><b>RESULTS</b>The ablation was successfully performed in all patients, with median operation time of 128 minutes (range, 45 to 180 minutes). No operative mortality or morbidity were noted during the study period. Freedom from AF was achieved in 12 patients (85.7%) during follow-up (median follow-up 9 months). One patient with persistent AF was shifted to paroxysmal AF. No atrial flutter or atrial tachycardia was noted during the follow-up.</p><p><b>CONCLUSION</b>These early results show that totally thoracoscopic surgical ablation using a unique "box lesion" procedure for persistent or paroxysmal AF is a feasible and effective method with good short-term results. Further study is necessary to validate this result.</p>
