Risk factors of dementia cognitive symptoms among older patients in Vietnam: A cross-sectional study

Background. Dementia has emerged as a significant contributor to declining quality of life and stands as a prominent factor in the increase of disability and dependency among elderly populations globally. This study aimed to explore the relationship between cognitive symptoms of dementia and their risk factors in individuals aged 60 years and older among Vietnamese outpatients who visited Geriatrics Clinic at University Medical Center of Ho Chi Minh city, Vietnam. Methods. 387 participants who were aged ≥ 60 years old were included in the cross-sectional study. Cognitive impairment was assessed by using the Mini Mental State Evaluation (MMSE) questionnaire. The functional limitations in activities of daily living (ADL) and Instrumental Activities of Daily Living (IADL), multimorbidity, and polypharmacy were also evaluated. Frailty was determined by The Canadian Study of Health and Aging Clinical Frailty Scale. Suffering dementia was determined when MMSE score was below 24 and IADL score less than 8. Results. People with dementia cognitive symptoms accounted for 22.74 % of the cohort. The percentage increased with age, and was higher in women than in men. Factors that increased the odds of having dementia symptoms were of older age, female, multimorbidity, Frailty Scale > Grade 4 and ADL dependency. Conclusions. Age, female gender, multimorbidity, frailty and ADL dependency were considered as risk factors of dementia cognitive symptoms among the Vietnamese people aged 60 years and older.

Obstetric service demand is the main health need of the Vietnamese population in Guangxi, China: A cross-sectional study.

China has become an emerging destination for international migration, especially in some Association of South East Asian Nations countries, but the situation of migrants seeking medical care in China remains unclear. A retrospective cross-sectional study was conducted in a hospital in Chongzuo, which provides medical services for foreigners, to investigate the situation of Vietnamese people seeking health care in Guangxi, China. Vietnamese patients who visited the hospital between 2018 and 2020 were included in the study. Demographic characteristics, clinical characteristics, characteristics of payment for medical costs, and characteristics of hospitalization were compared between outpatients and inpatients. In total, 778 Vietnamese outpatients and 173 inpatients were included in this study. The percentages of female outpatients and inpatients were 93.44% and 88.44% (χ2 = 5.133, P = .023), respectively. Approximately 30% of outpatients and 47% of inpatients visited the hospital due to obstetric needs. The proportions of outpatients with basic medical insurance for urban residents, basic medical insurance for urban employees, and new cooperative medical schemes were 28.02%, 3.21%, and 2.31%, respectively. In comparison, the proportion of inpatients with the above 3 types of medical insurance was 16.76%, 1.73%, and 2.31%, respectively. The proportion of different payments for medical costs between outpatients and inpatients were significantly different (χ2 = 24.404, P < .01). Middle-aged Vietnamese females in Guangxi, China, may have much greater healthcare needs. Their main medical demand is for obstetric services. Measurements should be taken to improve the health services targeting Vietnamese female, but the legitimacy of Vietnamese in Guangxi is a major prerequisite for them to access more and better healthcare services.

Association between asymptomatic hyperuricemia and knee osteoarthritis in older outpatients.

To investigate the association between asymptomatic hyperuricemia and knee osteoarthritis in older outpatients in Vietnam. This cross-sectional study included 257 older outpatients (195 in the knee osteoarthritis group and 62 in the non-knee osteoarthritis group) aged ≥60 years (mean age 73.31 ± 7.96 years) attending rheumatologic and geriatric clinics from November 2020 to May 2021. Data were collected for both groups, including demographics, symptoms and signs of knee osteoarthritis, serum uric acid levels, and knee radiographs. The association between asymptomatic hyperuricemia and knee osteoarthritis was assessed using logistic regression. The mean serum uric acid level among patients with knee osteoarthritis was higher than that among patients without knee osteoarthritis (6.3 ± 1.74 mg/dl vs. 5.71 ± 1.45 mg/dl, p = 0.017). Hyperuricemia was more common among older outpatients with knee osteoarthritis than among those without knee osteoarthritis (39% vs. 19%, p = 0.005). After adjusting for age, sex, body mass index (BMI), and other comorbidities, the association between asymptomatic hyperuricemia and knee osteoarthritis remained significant (odds ratio [OR] 2.61, 95% confidence interval [CI] 1.22-5.60, p = 0.013). Subgroup analyses were performed according to sex and BMI groups. Significant associations between asymptomatic hyperuricemia and knee osteoarthritis were observed among women (p = 0.017) and among individuals who were underweight-normal-weight according to BMI (p = 0.009). Asymptomatic hyperuricemia is a common comorbidity among older outpatients with knee osteoarthritis. An independent association was identified between asymptomatic hyperuricemia and knee osteoarthritis among older Vietnamese outpatients, although sex and BMI may be confounding factors that impact this association.

Medication Adherence of Vietnamese Outpatients with Chronic Diseases during the COVID-19 Pandemic.

The purpose of this study was to determine the medication adherence of outpatients with chronic diseases and the association between both patient attitudes and preventive practices regarding COVID-19 and their medication adherence. We performed a cross-sectional study in Vietnam. Medication adherence was determined using the translated and validated Vietnamese version of the General Medication Adherence Scale (GMAS). Patient attitudes and preventive practices regarding COVID-19 were measured using the 5K message of the Vietnam Ministry of Health (facemasks, disinfection, distance, no gatherings, health declarations). The associations between patient characteristics and medication adherence were determined by multivariable regression. The study included 1852 outpatients, and 57.6% of the patients adhered to their medications. Patients who recognized the pandemic’s obstruction of medical follow-ups (OR = 1.771; 95%CI = 1.461–2.147; p < 0.001), who applied ≥2 preventive methods (OR = 1.422; 95%CI = 1.173–1.725; p = 0.001), who were employed (OR = 1.677; 95%CI = 1.251–2.248; p = 0.001), who were living in urban areas (OR = 1.336; 95%CI = 1.090–1.637; p = 0.005,) who possessed higher education levels (OR = 1.313; 95%CI = 1.059–1.629; p = 0.013), or who had ≤2 comorbidities (OR = 1.293; 95%CI = 1.044–1.600; p = 0.019) were more likely to adhere to their medications. The adherence percentage for outpatients with chronic diseases was quite low during the pandemic. Patients who did not recognize the COVID-19 pandemic’s obstruction of medical follow-ups or who had poor preventive practices were less likely to adhere to medications. Healthcare providers should pay more attention to these groups to achieve desired treatment outcomes.

Pharmacist-led interventions to reduce drug-related problems in prescribing for Vietnamese outpatients

Pharmacist-led interventions to reduce drug-related problems in prescribing for Vietnamese outpatients

Appropriate Antibiotic Use and Associated Factors in Vietnamese Outpatients.

Background: Inappropriate antibiotic use among outpatients is recognized as the primary driver of antibiotic resistance. A proper understanding of appropriate antibiotic usage and associated factors helps to determine and limit inappropriateness. We aimed to identify the rate of appropriate use of antibiotics and identify factors associated with the inappropriate prescriptions. Methods: We conducted a cross-sectional descriptive study in outpatient antibiotic use at a hospital in Can Tho City, Vietnam, from August 1, 2019, to January 31, 2020. Data were extracted from all outpatient prescriptions at the Medical Examination Department and analyzed by SPSS 18 and Chi-squared tests, with 95% confidence intervals. The rationale for antibiotic use was evaluated through antibiotic selection, dose, dosing frequency, dosing time, interactions between antibiotics and other drugs, and general appropriate usage. Results: A total of 420 prescriptions were 51.7% for females, 61.7% with health insurance, and 44.0% for patients with one comorbid condition. The general appropriate antibiotic usage rate was 86.7%. Prescriptions showed that 11.0% and 9.5% had a higher dosing frequency and dose than recommended, respectively; 10.2% had an inappropriate dosing time; 3.1% had drug interactions; and only 1.7% had been prescribed inappropriate antibiotics. The risk of inappropriate antibiotic use increased in patients with comorbidities and antibiotic treatment lasting >7 days (p < 0.05). Conclusions: The study indicated a need for more consideration when prescribing antibiotics to patients with comorbidities or using more than 7 days of treatment.

Acculturation and severity of depression among first-generation Vietnamese outpatients in Germany.

Challenges of migration, particularly concerning the process of acculturation are associated with an increased risk of mental illness. Vietnamese migrants constitute the largest Southeast Asian migrant group in Germany, yet there is no data on the relationship between the mental health status and acculturation among this population. Therefore, the present study examines the relationship between two well-established dimensions of acculturation, that is, dominant society immersion (DSI) and ethnic society immersion (ESI), the four resulting acculturation strategies (integration, assimilation, separation and marginalization), and severity of depression. A sample of N = 113 first-generation Vietnamese outpatients from a psychiatric outpatient clinic for Vietnamese migrants in Germany was studied regarding their self-reported depressive symptoms (Beck Depression Inventory-II (BDI-II)) and acculturation (Stephenson Multigroup Acculturation Scale (SMAS)). Consistent with the hypotheses, patients reported less severe depressive symptoms, when they reported higher orientation toward the German and the Vietnamese society. Moreover, the results showed that integrated patients reported a lower severity of depression compared to marginalized patients, who reported the highest severity of depression. The findings indicate that among a sample of first-generation Vietnamese patients with depression, an orientation to both, the mainstream society and one's heritage society might serve as a potential resource. The rejection of any orientation to any society is associated with an increased risk for depression.

Acculturation strategies and severity of depression among Vietnamese migrants

AimsMigration with its long-term changes and the resulting task to adjust to the new environment has been associated with an increased risk for mental health problems. This study aims to gain further insight on the relationship between the fours acculturations strategies (integration, assimilation, separation, marginalization) and severity of depression.MethodsA total of n = 79 first generation Vietnamese outpatients from a psychiatric outpatient clinic for Vietnamese migrants in Germany were investigated regarding self-reported depressive symptoms (patient health questionnaire-9) and acculturation (Stephenson multigroup acculturation scale; SMAS).ResultsPatients with an integration acculturation strategy reported lower severity of depression compared to marginalized patients, who reported the highest severity of depression.ConclusionThe results implicate that the integration of both the mainstream society and the ethnic society might serve as a resource, whereas the rejection of both societies might increase the risk of depression.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Nutritional status of Vietnamese outpatients with chronic obstructive pulmonary disease.

Nutritional screening and assessment is not currently part of routine clinical practice in Vietnam. Therefore, the present study aimed to investigate the utility of the commonly used methods for identifying malnutrition in outpatients with chronic obstructive pulmonary disease (COPD). A cross-sectional pilot study and a larger retrospective study were carried out in outpatients with COPD who were attending a respiratory clinic in Ho Chi Minh City, Vietnam. Routine clinical data were collected [body mass index (BMI), forced expiratory volume in 1s (FEV1 )]. Nutritional screening and assessment were performed using the Malnutrition Screening Tool (MST) and Subjective Global Assessment (SGA) as the gold standard to diagnose malnutrition. In total, 393 outpatients had documented BMI and 29 were prospectively assessed using SGA: males, n=25; females, n=4; mean (SD) age 69.7 (9.6)years; mean (SD) BMI 21.0 (3.4)kgm-2 ; mean (SD) FEV1 percentage predicted 57.0% (19.7%). Malnutrition risk was identified in 20.7% (n=6) of patients using the MST (38% sensitivity; 94% specificity). However, 45% (n=13) were diagnosed as malnourished using the SGA (31% mild/moderate; 14% severe). All malnourished patients not identified by the MST had evidence of muscle wasting. BMI had a strong negative correlation with muscle wasting as assessed using the SGA (r=-0.857, n=28; P<0.001) and all malnourished patients had a BMI <21kgm-2 (range 14.6-20.8kgm-2 , nourished range 20.0-27.6kgm-2 ). Malnutrition is common in Vietnamese outpatients with COPD. A BMI threshold of <21kgm-2 appears to represent a useful and pragmatic cut-off point for identifying outpatients requiring comprehensive nutritional assessment and support.

The Use of Traditional Vietnamese Medicine Among Vietnamese Immigrants Attending an Urban Community Health Center in the United States.

Little is known about Traditional Vietnamese Medicine (TVM) and its use among Vietnamese immigrants in the United States. This study aimed to characterize TVM and improve understanding of its use among Vietnamese outpatients attending an urban clinic. This cross-sectional observation study was performed by mailing bilingual surveys to a stratified random sample of 400 Vietnamese adult patients (≥18 years of age) who had visited a community health center in Boston, Massachusetts, at least once in the prior 12 months. The data were analyzed by using descriptive and multivariable regression statistics. The use of TVM and the factors influencing their use were reported. Among the 216 respondents, 68% reported using TVM. Of those users, the median age was 56 years and 68% were female, 51% had lived in the United States for less than 13 years, and 91% spoke English "not well or not at all." Among the 89% who reported using TVM of indigenous origin, 62% used "wind scraping," 35% used herbal pills/products, and 30% used "wind snatching." Sixty-one percent used therapies of foreign origin; of those, 51% used Asian-originated TVM (herbs, 25%; Eastern massage, 23%) and 38% used Western-influenced TVM (diet supplements, 28%; Western massage, 8%). TVM was mostly used for pain conditions (57%), "staying well" (38%), and cough/colds (27%). Forty-five percent ignored the question on revealing TVM use to providers; of those who answered, 57% said "no." Fifty-one percent of TVM users reported using Western medicine for the same problem, while 46% used TVM and Western medicine within 2 days of each other. Self-rated health (odds ratio [OR], 2.61; 95% confidence interval [CI], 1.34-5.06), household size (OR, 2.09; 95% CI, 1.04-4.22), and education (OR, 2.65; 95% CI, 1.03-6.80) were associated with TVM use. TVM is an important component of the healthcare of urban Vietnamese and needs to be further investigated. Healthcare providers need to encourage open discussion to better care for this population.

EPA-0441 – Somatic and depressive symptoms in first generation (fg) vietnamese and german outpatients with major depression

Background Studies in general and psychiatric populations have mainly reported higher rates of somatisation in immigrants. Cross-cultural studies, confirmed that East-Asian non-immigrant patients reported fewer psychological and more somatic symptoms in depression. However studies on somatisation in depression are lacking for Vietnamese migrants in Europe. Objectives To explore whether Vietnamese outpatients, who utilized a psychiatric outpatient clinic in Germany had a tendency to present more somatic symptoms in depression. Methods For FG Vietnamese outpatients, psychological symptoms were assessed by depression-scale (PHQ-9) and somatic symptoms were assessed by the Somatic-symptom-scale (PHQ-15) in Vietnamese language by a Vietnamese psychiatrist. German outpatients who were assessed in the same outpatient clinic where matched for age, gender and diagnosis of MDE. Differences in PHQ-9 and PHQ-15 scales where analyzed with an ANOVA and single-item-differences of PHQ where analyzed with Mann-Whithney-Tests. Results 43 FG Vietnamese immigrants and 43 native german outpatients where included. While we found no differences on the total score of the PHQ-9 between both groups, FG-Vietnamese outpatients had an overall higher total score on somatic-symptom-scale PHQ-15. When analyzing somatic items FG-Vietnamese outpatients reported significantly more somatic symptoms of headache, chest-pain, dizziness and fainting. Conclusions Depressed Vietnamese outpatients reported psychological symptoms of depression at similar levels as matched native German outpatients. Vietnamese outpatients had a higher total score for somatic symptoms, and that difference was driven by a subset of somatic items. We concluded, that emphasis on somatic symptoms does not reflect a minimization of psychological symptoms in FG-Vietnamese outpatients seeking help for depression.

The Asthma Control Test (ACT) as an alternative tool to Global Initiative for Asthma (GINA) guideline criteria for assessing asthma control in Vietnamese outpatients

To determine the reliability and validity of the Asthma Control Test (ACT) to detect Global Initiative for Asthma (GINA)-defined uncontrolled or partly controlled asthma, and to determine the agreement between ACT and GINA in classifying asthma control among Vietnamese patients. A cross-sectional study was performed in 323 of 360 invited outpatients with asthma in Ho Chi Minh City to compare the ACT and GINA classification for asthma control. Internal consistency of the ACT (Cronbach's alpha) was 0.83. The kappa coefficient of 0.55, based on the ternary split, represents moderate agreement between the two rating systems with a correctly classified rate of 75%. The area under the receiver operating characteristics curve for the ACT score predicting GINA control was 0.85. To detect GINA-defined 'not controlled asthma', the ACT had a sensitivity of 70%, specificity of 93%, and a positive predictive value of 89%, with a cut-off point of 19. The validity of the ACT with regard to agreement with the GINA classification was consistent across both sexes, but less so in adolescents or younger adults. The ACT score was significantly correlated with the percentage predicted forced expiratory volume in 1 second (r=0.35, p<0.001) and percentage predicted peak expiratory flow (r=0.26, p<0.001). The Vietnamese ACT is useful for identifying outpatients with GINA-defined uncontrolled or partly controlled asthma.

Headache and complement C'1-esterase inhibitor deficiency in Vietnamese immigrants living in southern California.

The objective was to measure complement C'1-esterase inhibitor (C1INH) in a group of Vietnamese outpatients with headache. All 51 patients (7 males and 44 females), with either migraine or chronic tension-type headache, were evaluated during 1994 and 1995. Their ages ranged from 15 to 69 years old (mean age, 37.5 years). They were found to have low levels of C1INH (mean, 11 +/- 2 mg/dL versus control subjects, 15 +/- 2 mg/dL with p < 0.0001). Twenty patients (5 males and 15 females) were treated with a low dose of danazol, 200 mg daily for 1-2 months. The improvement of the headache coincided with the return to normal levels of C1INH in all of our patients (pretreatment, 11 +/- 2 mg/dL versus post-treatment, 16 +/- 2 mg/dL with p < 0.001). The levels of C1q and C4d/C4 ratios did not change as a result of treatment with danazol. Our patients may represent a form of androgen-responsive headache, which is associated with low levels of C1INH, normal levels of C1q and normal C4d/C4. It differentiated them from angioedema (hereditary or acquired form); they had no known precipitating factors or a family history of angioedema.

Complement abnormalities with lower extremities discomfort in Vietnamese immigrants.

The objective was to measure complement C'l esterase inhibitor (CIINH) in a group of Vietnamese outpatients with lower extremities discomfort of undetermined etiology. All 25 female patients were followed between 1992 and 1995. Their age ranged from 24 to 82 years old (mean age, 46.68 +/- 13.77). They presented with unexplained lower extremities discomfort. They were found to have low levels of CIINH (mean, 11.36 +/- 1.44 mg/dL versus control subjects, 15.64 +/- 2.22 mg/dL). Twenty-one patients were treated with oral Danazol 200 mg daily for 1-2 months. The improvement of the symptoms in our patients coincided with increased CIINH level in all of our patients (pretreatment, 11.33 +/- 1.46 mg/dL versus posttreatment, 16.82 +/- 2.98 mg/dL with p < 0.001) and the return to normal functional activity of CIINH associated with and without Danazol treatment. These patients may represent a form of androgen-responsive limited to the lower extremity's discomfort associated with low levels of CIINH, normal levels of Clq and normal ratio of C4d/C4 that differentiated them from angioedema (hereditary or acquired form), having no known precipitating factors or a family history of hereditary angioedema.
