ABSTRACT

Purpose>Booming mobile shopping has resulted in an increase use of m-payment. Although m-payment is still in its infancy in Thailand, it has started to affect the daily lives of Thai people. This study aims to understand the role of perceive risks in influencing millennials' intention to use m-payment for mobile shopping.Design/methodology/approach>The sample covers 250 millennials in Bangkok who were surveyed between February to May 2019. Purposive sampling and convenient sampling were applied to collect data. Partial least squares structural equation modelling (PLS-SEM) was applied for statistical analysis. Further, mediation effect of attitude was studied.Findings>The results showed that only perceived time risk significantly but negatively affect millennials' attitude towards using m-payment. Moreover, mediation test confirms that the relationship between perceived time risk and intention to use m-payment is mediated by attitude.Research limitations/implications>First, limited number of respondents cannot be a representative of millennials as a whole. Second, the study is limited to a general study, in which the results of m-payment might not be effectual to explain other scenarios (e.g. offline setting) and the market situation in another cultural context.Practical implications>It is important that business practitioners should formulate less complicated system under the most decent transaction time to elicit positive attitude towards m-payment. Also, message should emphasize on the time being saved and simplicity of the m-payment.Originality/value>Since the study of how perceived risks influence millennials intention to m-payment remains insufficient in Southeast Asian context especially in Thailand, this paper contributes to the updating of empirical findings to the existing literatures.

ABSTRACT

Background: As the coronavirus disease 2019 (COVID-19) pandemic progressed globally, school closures and home quarantine may cause an increase in problematic Internet use among students in universities. Such a traumatic stress event may also contribute to the development of posttraumatic stress disorder (PTSD), depressive, and anxiety symptoms. This study aimed to evaluate the prevalence of PTSD, depressive, and anxiety symptoms as well as the predictive role of problematic Internet use in the above-mentioned psychological problems in university students. Methods: A cross-sectional study was conducted through an online survey of 8,879 students in China between April 20 and April 26, 2020. The presence of PTSD, depressive, and anxiety symptoms and problematic Internet use were evaluated using PTSD Checklist for DSM-5, the Center for Epidemiologic Studies Depression 9-item scale, the generalized anxiety disorder 7-item scale, and the Young diagnostic questionnaire, respectively. Sociodemographic information and the knowledge, attitude, and practice (KAP) toward COVID-19 data were also collected. Results: A total of 4,834 (54.4%) participants were female, and 7,564 (85.2%) were undergraduate students. A total of 615 students (6.9%) reported PTSD symptoms; 5.2% (465) and 10.1% (896) reported moderate to severe depressive and anxiety symptoms, respectively. The problematic Internet use was significantly associated with higher risk of PTSD, depressive, and anxiety symptoms (odds ratio 2.662 [95% CI, 2.239-3.165], odds ratio 4.582 [95% CI, 3.753-5.611], odds ratio 3.251 [95% CI, 2.814-3.757], respectively; all P < 0.001). Lower attitude and practice scores also contributed to the risk of depressive, anxiety, and PTSD symptoms (P < 0.05). Conclusions: Psychological problems should be paid more attention, and problematic Internet use may be a predictor when screening high-risk students for psychological problems. Our results will aid in timely psychological screening, which is meaningful in the prevention and intervention of psychological problems.

ABSTRACT

OBJECTIVE: During the coronavirus disease 2019 (COVID-19) pandemic, exploring insulin resistance and beta-cell activity is important for understanding COVID-19‒associated new-onset diabetes. We assessed insulin sensitivity and fasting insulin secretion in patients with COVID-19 without diabetes on admission and at 3 and 6 months after discharge. METHODS: This 6-month prospective study assessed data from the records of 64 patients without diabetes diagnosed with COVID-19 at Wenzhou Central Hospital, China. Each patient was followed up at 3 and 6 months after discharge. Repeated measures analysis of variance was used to investigate differences in multiple measurements of the same variable at different times. Linear regression analysis was performed to analyze the contributor for changes in the triglyceride-glucose (TyG) index. RESULTS: Fasting C-peptide levels in patients at baseline were lower than the normal range. Compared with the baseline results, patients had significantly elevated fasting C-peptide levels (0.35 ± 0.24 vs 2.36 ± 0.98 vs 2.52 ± 1.11 µg/L; P < .001), homeostasis model assessment for beta-cell function (0.42, interquartile range [IQR] 0.36-0.62 vs 2.54, IQR 1.95-3.42 vs 2.90, IQR 2.02-4.23; P < .001), and TyG indices (8.57 ± 0.47 vs 8.73 ± 0.60 vs 8.82 ± 0.62; P = .006) and decreased fasting glucose levels (5.84 ± 1.21 vs 4.95 ± 0.76 vs 5.40 ± 0.68 mmol/L; P = .003) at the 3- and 6-month follow-up. Male gender, age, interferon-alfa treatment during hospitalization, and changes in total cholesterol and high-density lipoprotein levels were significantly associated with changes in the TyG index. CONCLUSION: Our study provided the first evidence that COVID-19 may increase the risk of insulin resistance in patients without diabetes.

ABSTRACT

The effect of acupuncture-moxibustion on respiratory system and systemic immune inflammatory response were reviewed to explore the possible role of neuroimmunomodulation in the control of inflammatory response and the effect mechanism of cholinergic anti-inflammatory pathway on coronavirus disease 2019 (COVID-19). Acupuncture-moxibustion could produce the local and systemic anti-inflammatory effect on COVID-19 through the activation of cholinergic anti-inflammatory pathway. Compared with humoral anti-inflammatory pathway, the neuronal anti-inflammatory pathway has earlier initiation, rapider action, and more localization, which play a more important role in the initial stage of inflammatory response. This may be an important basis for acupuncture-moxibustion intervention in the early stage of COVID-19. In addition to cholinergic anti-inflammatory pathway, acupuncture-moxibustion may also play an anti-inflammatory role in activating sympathetic nerve, hypothalamic-pituitary-adrenal axis and other neural anti-inflammatory pathways. How acupuncture-moxibustion play its role in stimulating the vagus nerve and sympathetic nerve in different periods of inflammatory response, and whether the effect is based on the selection of acupoints and the methods of stimulation, will be the research direction of the transformation from basic research to clinical research for acupuncture-moxibustion.

ABSTRACT

AIMS: Coronavirus disease 2019 (COVID-19) has become a recognized worldwide pandemic. Researchers now know that mortality from COVID-19 can be reduced through early prevention measures. This retrospective, multi-centered study of 293 COVID-19 patients without diabetes explores the association between fasting blood glucose (FBG) levels and the risk of COVID-19 disease progression, with the goal of providing clinical evidence for glycemic targets in patients. METHODS: The multivariate stepwise binary logistic regression analysis was used to test the dose-response effects of FBG levels on the risk of severe and critical condition in COVID-19 patients. RESULTS: FBG levels were plotted in quintiles with set at <4.74, 4.74-5.21, 5.21-5.78, 5.78-7.05, and ≧7.05 mmol/L. The constituent ratio of severe or critical cases in each FBG quintile was 20.7%, 1.7%, 13.8%, 27.1%, and 67.2%, respectively (P < 0.0001). When the second quintile was used as the reference, the adjusted odds ratios (AORs) (95%CI) for the risk of severe/critical condition in COVID-19 was 25.33 (2.77, 231.64), 1.00 (Reference), 3.13 (0.33, 29.67), 10.59 (1.23, 91.24), 38.93 (4.36, 347.48) per FBG quintile respectively (P < 0.001). CONCLUSIONS: We provide evidence of J-shaped associations between FBG and risk of severe and critical condition in non-diabetes patients with COVID-19, with nadir at 4.74-5.78 mmol/L.

ABSTRACT

We report epidemiological and clinical investigations on ten pediatric SARS-CoV-2 infection cases confirmed by real-time reverse transcription PCR assay of SARS-CoV-2 RNA. Symptoms in these cases were nonspecific and no children required respiratory support or intensive care. Chest X-rays lacked definite signs of pneumonia, a defining feature of the infection in adult cases. Notably, eight children persistently tested positive on rectal swabs even after nasopharyngeal testing was negative, raising the possibility of fecal-oral transmission.
