Plain language summary
Stroke refers to a clinical syndrome of localized or global brain dysfunction caused by cerebrovascular disease. It has the characteristics of rapid onset, high morbidity, high mortality, and high disability. After a stroke, various dysfunction can be caused, and dysphagia is one of the most common symptoms. The acidity of vitamin C can promote the secretion of saliva by stimulating the tongue, which can accelerate the swallowing action, thereby improving the swallowing function. The aim of this study was to explore the effects of vitamin C stimulation on the rehabilitation process, Nourishment State Index and immune function indicator of stroke patients with dysphagia. This study is a randomised controlled trial which enrolled 120 participants with dysphagia. The participants were randomly assigned into control group and vitamin C stimulation group, with 60 cases in each group. Results show that vitamin C acid stimulation significantly improves rehabilitation, and the Nourishment State Index and Immune Function Index of stroke patients with dysphagia. Authors conclude that Vitamin C acid stimulation can further improve the nutritional status and immune function after stroke and promote post-operative recovery of patients. Thus, vitamin C stimulation therapy can be widely used in stroke rehabilitation management.
Abstract
BACKGROUND Stroke is a clinical syndrome of localized or global brain dysfunction caused by cerebrovascular disease. AIM: The aim of this study was to explore the effect of vitamin C acid stimulation on the rehabilitation process, Nourishment State Index and immune function indicators of stroke patients with dysphagia. DESIGN This is a prospective cohort study. SETTING This study was conducted at our hospital. POPULATION We analyzed stroke patients with dysphagia. METHODS A total of 120 stroke patients with dysphagia were randomly divided into a routine group and a test group, with 60 cases in each group. Routine swallowing training was performed in the routine group, and the test group was stimulated with vitamin C acid. The water swallow test (WST) and video fluoroscopic swallowing study (VFSS) were used to compare the rehabilitation of dysphagia in the two groups. Nourishment State Index was evaluated by BMI, serum albumin, total serum protein and hemoglobin. Immune Function Index was evaluated by IgA, IgM and IgG. RESULTS Compared with the control group, the WST level of patients treated with vitamin C acid stimulation intervention were significantly reduced, and the VFSS score were significantly increased. Serum levels of hemoglobin, albumin, total protein, IgA, IgM and IgG in the vitamin C acid stimulation group were remarkably increased than those in the control group. CONCLUSIONS Vitamin C acid stimulation exhibits a good application effect in patients with dysphagia after stroke. Moreover, vitamin C acid stimulation can further improve the nutritional status and immune function after stroke and promote postoperative recovery of patients. Therefore, we believe that vitamin C stimulation therapy can be widely used in stroke rehabilitation management. CLINICAL REHABILITATION IMPACT Vitamin C acid stimulation significantly improves rehabilitation of stroke patients with dysphagia and ameliorates the nutritional status and immune function of patients.

Plain language summary
The treatment of obesity has become a public health priority given the negative impact of this condition on physical and mental health. The aim of this study was to compare the effects of energy restriction alone or in combination with induced cognitive dietary restraint (CDR) on eating behaviour traits, appetite sensations, and markers of stress in overweight and obese premenopausal women. The study is a single-blinded randomised clinical study which recruited premenopausal women aged between 26 and 50 years. The participants were randomised to either an energy-restriction-plus-induced CDR condition (CDR+group) or an energy-restriction-without induced CDR condition (CDR−group). Results indicate that inducing CDR in a context of energy restriction had no further effects on eating behaviour traits, appetite sensations, and markers of stress in the short term as well as in the longer term than energy restriction alone. Authors conclude that increasing CDR has no negative impact on factors regulating energy balance in the context of energy restriction.
Abstract
Weight loss has been associated with changes in eating behaviors and appetite sensations that favor a regain in body weight. Since traditional weight loss approaches emphasize the importance of increasing cognitive dietary restraint (CDR) to achieve negative energy imbalance, it is difficult to untangle the respective contributions of energy restriction and increases in CDR on factors that can eventually lead to body weight regain. The present study aimed at comparing the effects of energy restriction alone or in combination with experimentally induced CDR on eating behavior traits, appetite sensations, and markers of stress in overweight and obese women. We hypothesized that the combination of energy restriction and induced CDR would lead to more prevalent food cravings, increased appetite sensations, and higher cortisol concentrations than when energy restriction is not coupled with induced CDR. A total of 60 premenopausal women (mean BMI: 32.0 kg/m2; mean age: 39.4 y) were provided with a low energy density diet corresponding to 85% of their energy needs during a 4-week fully controlled period. At the same time, women were randomized to either a condition inducing an increase in CDR (CDR+ group) or a condition in which CDR was not induced (CRD- group). Eating behavior traits (Three-Factor Eating Questionnaire and Food Craving Questionnaire), appetite sensations (after standardized breakfast), and markers of stress (Perceived Stress Scale; postawakening salivary cortisol) were measured before (T = 0 week) and after (T = 4 weeks) the 4-week energy restriction, as well as 3 months later. There was an increase in CDR in the CDR+ group while no such change was observed in the CDR- group (p=0.0037). No between-group differences were observed for disinhibition, hunger, cravings, appetite sensations, perceived stress, and cortisol concentrations. These results suggest that a slight increase in CDR has no negative impact on factors regulating energy balance in the context of energy restriction.
