ABSTRACT
BACKGROUND/OBJECTIVES@#The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. @*SUBJECTS/METHODS@#We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. @*RESULTS@#Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products.Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements.This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. @*CONCLUSION@#This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.
ABSTRACT
BackgroundIn December 2019, human infection with a novel coronavirus, known as SARS-CoV-2, was identified in Wuhan, China. The mortality of critical illness was high in Wuhan. Information about critically ill patients with SARS-CoV-2 infection outside of Wuhan is scarce. We aimed to provide the clinical features, treatment, and prognosis of the critically ill patients with SARS-CoV-2 infection in Guangdong Province. MethodsIn this multi-centered, retrospective, observational study, we enrolled critically ill patients with SARS-CoV-2 pneumonia who were admitted to the intensive care unit (ICU) in Guangdong Province. Demographic data, symptoms, laboratory findings, comorbidities, treatments, and prognosis were collected. Data were compared between patients with and without intubation. ResultsForty-five critically ill patients with SARS-CoV-2 pneumonia were identified in 7 ICUs in Guangdong Province. The mean age was 56.7 years, and 29 patients (64.4%) were men. The most common symptoms at the onset of illness were high fever and cough. Majority of patients presented with lymphopenia and elevated lactate dehydrogenase. Treatment with antiviral drugs was initiated in all the patients. Thirty-seven patients (82.2%) had developed acute respiratory distress syndrome, and 13 (28.9%) septic shock. A total of 20 (44.4%) patients required intubation and 9 (20%) required extracorporeal membrane oxygenation. As of February 28th 2020, only one patient (2.2%) had died and half of them had discharged of ICU. ConclusionsInfection with SARS-CoV-2 in critical illness is characterized by fever, lymphopenia, acute respiratory failure and multiple organ dysfunction. Compared with critically ill patients infected with SARS-CoV-2 in Wuhan, the mortality of critically ill patients in Guangdong Province was relatively low. These data provide some general understandings and experience for the critical patients with SARS-CoV-2 outside of Wuhan.
ABSTRACT
Objective To observe the effect of bisoprulol on malignant ventricular arrhythmia (MVA) and heart rate turbulence (HRT) in ambulatory electrocardiogram monitoring for twenty-four hours in patients with unsta-ble angina pectoris (UAP). Methods 40 UAP patients with premature ventricu]ar beats were observed. All patients were examined with ambulatory electrocardiogram monitoring for twenty-four hours before and after bisoprolol (5mg, Qd) was administered for 7 days. The number of patients with MVA、turbulence onset (TO) and turbulence slope (TS) were analyzed. Results After bisoprolol was administered for 7 days in patients with UAP,the number of pa-tients with MVA decreased by 14.2%. TO decreased and TS increased, and HRT was improved. Conclusions HRT had clinical prognostic value for malignant ventricular arrhythmia and sudden death in patients with UPA. Bisoprolol can improve HRT and reduce the incidence of MVA.
ABSTRACT
Objective To explorer the clinical effects of Pentoxifylline(PTX group) with mechanical ventilation in patients with acute respiratory distress syndrome(ARDS). Methods 64 patients with ARDS were randomized into a control group(n = 32 ,ARDS conventional treatment) and a PTX group(n = 32 ,PTX 50ml iv bid in addition to the conventional treatment). The patients were closely monitored with their curative effect, blood gas indexes and serum levels of TNF-α and IL-8 after the treatment. Results The PaO_2 and PaO_2/FiO_2 got significantly higher in the PTX group than in the control group on 3d and 7d (P ＜ 0.05). The serum levels of TNF-α and IL-8 and the mortality of ARDS were significantly decreased in the PTX group after the combined with Pentoxifylline (P ＜ 0.05 or P ＜0.01). Conclusion The treatment combined with the Pentoxifylline can effectively improve the Oxygenation and prognosis of ARDS patients by inhibiting the inflammatory responses.
ABSTRACT
Objective To explore the efficiency of temporary cardiac pacing on the acute poisoning patients with serious bradycardia.Methods Thirty-eight cases of the acute poisoning patients with serious bradycardia were treated randomly with temporary cardiac pacing (pacing group, 18 cases) and drug therapy (control group,20 cases) and followed with treatment for poisoning. Results Right ventricular pacing were successfully performed in 18 cases and the temporary cardiac pacemaker were placed. With the further treatment of poisoning, in the pacing group, the efficiency of anit-bradycardia and the poisoning cure rate was 100% and 88. 9% , respectively, whereas being 60% and 65.0% in the control group, respectively. The efficiency of anit-bradycardia and the poisoning cure rate were significantly different between the two groups (P < 0.01 or P < 0.05 ). Conclusions The treatment of temporary cardiac pacing has effect on the acute poisoning patients with serious bradycardi. It can effectively improve the rate of patients' resuscitation.
ABSTRACT
Objective To explore the value of using the temporary cardiac pacing on the acute poisoning patients with serious bradycardia. Methods 38 cases of the acute poisoning patients with serious bradycardia patients were treated randomly with temporary cardiac pacing(pacing group,18 cases) and drug therapy(control group,20 cases) and then treated their poisoning. Results 18 cases of pacing group were right ventricular pacing successfully and placed the temporary cardiac pacemaker,with the further treatment of poisoning, the efficiency of anti-bradycardia was 100% ,the poisoning cure rate was 89% ;The control group were 60% and 65% respectively;There were statistically significant difference between two groups ( P < 0.05 ). Conclusion The treatment of temporary cardiac pacing were exactly for the acute poisoning patients with serious bradycardia. It could effectively improve the rate of patients' resuscitation.
ABSTRACT
Objective To evaluate timing of tracheal intubation impact on the therapeutic effect of acute severe organophosphate poisoning( ASOPP) patients. Methods Retrospectively analyze 82 ASOPP patients with respiratory failure ( RF). The patients were divided into timely tracheal intubation group(n = 42) and delay tracheal intubation group (n =40) ,and compare the therapeutic effect of these two groups. Results Compared with timely tracheal intubation patients and delay tracheal intubation patients,total time of mechanical ventilation,hospital day decreased significantly (P<0.01) ,cure rate increased significantly (P<0.01) ,but complications [intermediate myasthenia syndrome (IMS) .pulmonary infection,cardiac damage and so on] had no significant difference(P>0.05). Conclusion It was exact that the therapeutic effect of timely tracheal intubation on rescuing the ASOPP patients, and the best time to tracheal intubation was in RF early period.
ABSTRACT
Objective To evaluate the intrathecal injection of combining methotrexate (MTX) and dexamethasone (DXM) into lupus patients with central nervous system involvement. Methods Twenty-eight cases of central nervous system involvement with systemic lupus erythematosus (SLE) accepted intrathecal injection of MTX plus DXM. Data including clinical manifestations, cerebrospinal fluid and skull CT or MRI before and after treatment were analyzed. Meanwhile, the mortalities between 28 cases treated with intrathecal injection and 57 cases received normal management without intrathecal injection were compared. Results Intrathecal injection of MTX plus DXM was given to 26 SLE-central nervous system (CNS) patients except 2 cases death. The symptoms and signs were remitted or relieved obviously including the decrease of pressure and protein and elevation of glucose in cerebrospinal fluid. Positive ANA in 6 cases had turned to negative after treatment. Conclusion Without any severe side effects, intrathecal injection with MTX plus DXM yielded satisfactory effects on patients with SLE-CNS, particularly in those with focus manifestations.
