Dietary inflammation index is associated with dyslipidemia: evidence from national health and nutrition examination survey, 1999-2019.

BACKGROUND AND AIMS: This study aimed to investigate the association between the Dietary Inflammatory Index (DII) and dyslipidemia, as well as to evaluate the mortality risk associated with DII in participants with dyslipidemia. METHODS: Data from the National Health and Nutrition Examination Survey database were divided into dyslipidemia and non-dyslipidemia groups. The association between DII and dyslipidemia was investigated using the weighted chi-square test, weighted t-test, and weighted logistic regression. Weighted Cox proportional hazards models were used to estimate the hazard ratios and 95% confidence intervals for all-cause and cardiovascular disease-related mortality within the dyslipidemia group. RESULTS: A total of 17,820 participants, including 4,839 without and 12,981 with dyslipidemia were analyzed in this study. The results showed that DII was higher in the dyslipidemia group compared to the non-dyslipidemia group (1.42 ± 0.03 vs. 1.23 ± 0.04, P < 0.01). However, for energy, protein, carbohydrates, total fat, saturated fat, and iron, DII was lower in participants with dyslipidemia. Logistic regression analysis revealed a strong positive association between DII and dyslipidemia. The odds ratios for dyslipidemia from Q1 to Q4 were 1.00 (reference), 1.12 (0.96-1.31), 1.23 (1.04-1.44), and 1.33 (1.11-1.59), respectively. In participants with dyslipidemia, a high DII was associated with high all-cause and cardiovascular mortality. CONCLUSION: DII was closely associated with dyslipidemia. A pro-inflammatory diet may play a role in unfavorable consequences and is linked to both all-cause mortality and cardiovascular death in patients with dyslipidemia. Participants with dyslipidemia should pay attention to their anti-inflammatory dietary patterns.

Clinical study of vitamin A combined with vitamin B in prevention and treatment of anemia in premature infants.

BACKGROUND: We explored the clinical efficacy of vitamin A combined with vitamin B in the prevention and treatment of premature infants with anemia. METHODS: One hundred fifty cases of premature infants were divided into three groups. Vitamin A combined with recombinant human erythropoietin (group A), vitamin B combined with recombinant human erythropoietin (group B), vitamin A combined with vitamin B combined with recombinant human erythropoietin treatment (recorded as group C). Levels of serum ferritin (SF), hemoglobin (Hb), hematocrit (Hct) and reticulocyte (Ret) in the serum of children before and after treatment were compared with those of three different treatments. RESULTS: After treatment, the levels of SF, Hb and Ret in group C were higher than those in group A and B, and the level of Hct in group C was lower than that in group A and B (P<0.05) There was no significant difference in SF, Hb, Hct and Ret between the two groups (P>0.05). The ratio of blood transfusion in group C was lower than that in group A and B (P<0.05). There was no significant difference between the two groups (P>0.05). CONCLUSIONS: Vitamin A combined with vitamin B can effectively prevent anemia in premature infants, which has important clinical significance.

Effect of serum uric acid on cognition in patients with idiopathic REM sleep behavior disorder.

Idiopathic rapid eye movement sleep behavior disorder (iRBD) likely represents the prodromal stage of synucleinopathy. The present study investigated how levels of serum uric acid (UA) affect cognition and motor function in patients with iRBD. A total of 42 patients with iRBD and 45 healthy controls were included. All participants were given cognitive tests and motor assessments. Serum UA concentrations were measured. The patients were further divided into two groups (high or low UA) according to serum UA level. The level of serum UA was similar between the patients with iRBD and the healthy controls, whereas the patients showed impaired executive, memory, and visuospatial functions. The patients with low UA levels had longer durations of RBD. Lower scores involving attention, executive function, and language domain were also found in the patients with low UA, whereas the scores of the patients with high UA were similar to those of the healthy controls. Regarding memory domain, the low UA group had worse scores than the healthy controls, whereas the scores of high UA group fell between those of the low UA group and the healthy controls. Motor function was not affected in any of the groups. UA affects cognitive function but not motor function in patients with iRBD, which could contribute to its antioxidant and neuroprotective roles.

The role of the Montreal Cognitive Assessment (MoCA) and its memory tasks for detecting mild cognitive impairment.

To investigate the role of the Montreal Cognitive Assessment (MoCA) (Beijing version) and its memory tasks on detecting different mild cognitive impairment (MCI) subtypes including amnestic MCI (aMCI) and nonamnestic MCI (naMCI) in memory clinics. A total of 121 patients with MCI and 53 healthy controls were included. Fifty-six aMCI-multiple domains (amMCI), 32 aMCI-single domain (asMCI), and 33 naMCI patients were diagnosed according to extensive cognitive tests. All participants were administered by the Mini Mental State Examination (MMSE) and the MoCA. Patients with amMCI performed worse than patients with asMCI, naMCI, and healthy controls on the MMSE and the MoCA (p < 0.001). The area under the curve (AUC) value for the MoCA when comparing the amMCI and control groups was 0.884 (p < 0.001), which was superior to that of the MMSE. The AUC value decreased to 0.687 when applied to the naMCI and control groups (p = 0.007), which was still higher than that of the Rey Auditory Verbal Learning Test (RAVLT) or the Rey-Osterrieth complex figure (ROCF). Delayed free recall or category prompted recall in the MoCA had roles in differentiating asMCI and controls groups with AUC value of 0.717 (p = 0.002) and 0.691 (p = 0.005), respectively. The MoCA is a good screening tool for detecting different types of MCI and is suitable for patients in outpatient clinics.

Transcranial sonography in idiopathic REM sleep behavior disorder and multiple system atrophy.

AIM: We investigated preclinical abnormalities as revealed by transcranial sonography (TCS) in patients with idiopathic rapid eye movement sleep behavior disorder (iRBD) compared with those revealed in patients with multiple system atrophy (MSA) or Parkinson's disease (PD) and in normal controls. METHODS: Twenty-two patients with iRBD, 21 patients with MSA, 22 patients with PD, and 21 normal controls were included in this study. All participants underwent one night of video-polysomnography monitoring, and the sleep parameters were analyzed using Polysmith software and by visual analysis. TCS was performed following a standardized procedure. The echogenicity of the substantia nigra and basal ganglia were evaluated. RESULTS: A greater proportion of PD patients were found to have substantia nigra hyperechogenicity (86.4%) when compared to iRBD patients (31.8%), MSA patients (23.8%), and normal controls (4.8%) (P < 0.001). Fourteen MSA patients (66.7%) and 11 iRBD patients (50.0%) had hyperechogenicity in the basal ganglia, whereas hyperechogenicity in the basal ganglia was less frequent in PD patients (18.2%) and normal controls (9.5%) (P < 0.001). Poor sleep efficiency, less stage II sleep time, and more periodic leg movements were found in MSA and PD patients, whereas iRBD patients had almost normal sleep. CONCLUSION: Some iRBD patients had basal ganglia hyperechogenicity that was similar to that observed in MSA, which may represent another possible convert direction. The present study further confirmed iRBD as a prodromal stage of synucleinopathy. TCS could detect subclinical changes and thus might provide useful markers for identifying individuals at increased risk for developing a synucleinopathy.

TCM Syndrome Recognition Model of Type 2 Diabetes Mellitus in Shanghai Based on TCM Inquiry Information.

Background: Type 2 diabetes mellitus (T2DM) has become one of the serious public health problems in China, and it affects the quality of survival of patients significantly. The long-term monitoring and early warning of T2DM and its complications should be paid attention to. Artificial diagnosis of T2DM in traditional Chinese medicine (TCM) is subjective and unrepeatable at the present stage. It is important to develop standardized collection and objective analysis methods of TCM inquiry. Therefore, we are interested in establishing syndrome recognition models. Objective: The establishment of the TCM syndrome recognition model of T2DM is helpful to the syndrome diagnosis of the disease, and the clear diagnosis of the syndrome is the prerequisite for the effective treatment of the disease by TCM. At present, there are few studies on syndrome recognition models of T2DM. Therefore, based on the inquiry information of TCM, we establish a latent structure model (LSM) of T2DM syndrome in Shanghai, hoping to provide services for the health management of TCM for diabetes in the future. Methods: A total of 587 effective samples of T2DM patients in Shanghai were collected. The gender, course of disease, and chronic complications were analyzed by one-way ANOVA and frequency analysis. Inquiry symptoms that could be included in the model were screened. In the study, 30 symptoms were used as observable variables to analyze the symptom information of TCM inquiry, and then, the TCM syndrome recognition model was established. Results: The clinical syndromes of patients with T2DM in Shanghai were mixed with deficiency and excess. The LSM divided the pattern of the disease into qi-yin deficiency pattern, yin deficiency pattern, qi deficiency pattern, and qi stagnation pattern. These patterns were mainly located in the spleen and stomach, liver, and kidney. Conclusion: The results of the syndrome classification of T2DM by LSM are basically consistent with the TCM clinical characteristics of the disease, which could reflect its main etiology and pathogenesis. The LSM of TCM inquiry syndrome diagnosis of T2DM confirmed the objectivity of TCM syndrome differentiation to some extent, and it will lay a foundation for the development of a mobile APP for TCM health management of T2DM.

The association between chronic heart failure and frailty index: A study based on the National Health and Nutrition Examination Survey from 1999 to 2018.

Objective: This study aims to explore the association between the frailty index and chronic heart failure (CHF). Methods: We collected data from the National Health and Nutrition Examination Survey (NHANES) (1998-2018) database to assess the association between CHF and frailty. Demographic, inquiry, laboratory examinations, and characteristics were gathered to compare CHF and non-CHF groups. Multiple logistic regression analysis was performed to explore the relationship between frailty and CHF. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence interval (CI) for mortality from all causes and cardiovascular disease (CVD). Results: A total of 16,175 participants with cardiac and cerebrovascular disease were categorized into CHF (n = 1,125) and non-CHF (n = 15,050) groups. In patients with CHF, the prevalence of frailty, pre-frailty, and non-frailty were 66.31, 30.93, and 2.75%, respectively. In multiple logistic regression, patients with CHF who were male (OR = 0.63, 95% CI: 3.11-5.22), whose annual family income was over $20,000 (OR = 0.52, 95% CI: 0.37-0.72, p < 0.001), or with normal hemoglobin level (OR = 0.77, 95% CI: 0.68-0.88, P < 0.001) had a lower likelihood of frailty. CHF patients with hypertension (OR = 3.60, 95% CI: 2.17-5.99, P < 0.0001), coronary heart disease (OR = 1.76, 95% CI: 1.10-2.84, P = 0.02), diabetes mellitus (OR = 1.89, 95% CI: 1.28-2.78, P < 0.001), and stroke (OR = 2.52, 95% CI: 1.53-4.15, P < 0.001) tended to be frail. Survival analysis suggested that pre-frailty and frailty were related to poor all-cause deaths (HR = 1.48, 95% CI: 1.36-1.66; HR = 2.77, 95% CI: 2.40-3.18) and CVD mortality (HR = 1.58, 95% CI: 1.26-1.97; HR = 2.55, 95% CI: 2.02-3.21). CHF patients with frailty were strongly connected with all-cause death (HR = 2.14, 95% CI: 1.27-3.62). Conclusion: Frailty was positively associated with CHF. Patients with CHF who were male, whose annual family income was over $20,000, or with normal hemoglobin level were negatively correlated to frailty. For patients with cardiac and cerebrovascular disease as well as CHF, frailty was strongly connected with all-cause death.

Correlation of vitamin D receptor with bronchial asthma in children.

This study was designed to investigate the correlation of vitamin D receptor (VDR) gene polymorphism with bronchial asthma in children. Seventy patients admitted to Daqing Longnan Hospital and diagnosed as bronchial asthma for the first time from April 2015 to May 2017 were selected as observation group. Patients received routine treatment and intervention. Seventy healthy subjects admitted to hospital during the same period were enrolled as the control group. Vitamin D gene polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism assay; the levels of total serum immunoglobulin E (IgE) in the two groups were determined by electrochemiluminescence immunoassay; lung function levels in patients were measured using PowerCube (Germany) pulmonary function instrument before and after treatment, and the relationship between VDR gene polymorphism and lung function in children with bronchial asthma was analyzed. The difference in comparison of base frequency of rs1544410 locus of VDR gene had no statistical significance between the two groups (P>0.05). The locus CC frequency of rs7975232 of VDR gene in observation group was lower in the observation group than that in the control group (P<0.05); the locus AC and AA frequencies of rs7975232 of VDR gene were higher in the observation group than those in the control group (P<0.05). The level of vitamin D was lower in the observation group than that in the control group (P<0.05); the level of total serum IgE was higher in the observation group than that in the control group (P<0.05). The forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) and the ratio of FEV1 to forced vital capacity (FVC) in children with bronchial asthma in the observation group were higher after treatment than those before treatment (P<0.05). The correlation research displayed that VDR gene polymorphism was negatively correlated with lung function levels in children with bronchial asthma (P<0.05). The results showed that children with bronchial asthma are often accompanied by different degrees of changes in VDR gene polymorphism, which is negatively correlated with the severity of asthma, so vitamin D should be strengthened to ameliorate the prognosis of children.

The prospective memory of patients with idiopathic REM sleep behavior disorder.

BACKGROUND: Idiopathic rapid eye movement sleep behavior disorder (iRBD) likely represents the prodromal stage of synucleinopathy. The present study was to investigate if there was prospective memory (PM) impairment and the relationship between different PM tasks and traditional cognitive tests in patients with iRBD. METHODS: A total of 28 patients with iRBD, 25 with Parkinson's disease (PD) and 21 healthy controls were included. The Cambridge Prospective Memory Test (CAMPROMPT) was used to measure the PM including time-based (TBPM) and event-based PM (EBPM). Standard cognitive tests were administered to all participants. RESULTS: EBPM scores were lower only in patients with iRBD, while the obvious PM abnormalities were found in patients with PD. The patients with iRBD and PD performed worse on delayed recall of the Rey Auditory Verbal Learning Test (RAVLT) and copy of the Rey-Osterrieth complex figure (ROCF). The EBPM correlated with attention, executive function, and immediate memory besides working memory in patients with iRBD. The PM tasks involved in more memory functions in PD patients. CONCLUSIONS: The patients with iRBD were impaired on both episodic memory and EBPM tasks that correlated with attention, executive function, and immediate memory. The PM abnormality was an early cognitive change in iRBD to which more attention should be paid more attention.

Cognitive study on Chinese patients with idiopathic REM sleep behavior disorder.

AIMS: We investigated cognitive abnormalities using standard tests in Chinese patients with idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD) compared with those in normal controls. METHODS: Twenty-three patients with iRBD and 23 normal controls were included in this study. All of the participants underwent one night of video-polysomnography (PSG) monitoring to certify REM sleep without atonia or abnormal behaviors. The cognitive assessments were administered and scored according to a standard procedure, including global cognitive screening and attention/processing speed, executive function, memory, language, and visuospatial ability testing. RESULTS: Patients with iRBD had similar scores of the Mini Mental State Examination (MMSE) but lower Montreal Cognitive Assessment (MoCA) scores compared with controls (p>0.05, p=0.013). The iRBD patients performed poorly on verbal memory tests, which included immediate recall (p<0.001), delayed recall (p<0.001), and false recognitions (p=0.002) of the Rey Auditory Verbal Learning Test (RAVLT). The visual memory and visuospatial abilities were also impaired in iRBD patients, as reflected by the copy (p=0.005) and immediate (p=0.004) and delayed (p=0.003) recall of the Rey-Osterrieth complex figure, although no difference was found after Bonferroni correction. The duration of RBD was 6.98±8.10years. After controlling for age, the duration of RBD was only correlated with the Trail Making Test B (r=0.613, p=0.045) and block design (r=-0.667, p=0.025). CONCLUSIONS: Impaired verbal memory was observed in iRBD patients who identified as Chinese. MoCA could detect cognitive abnormalities and serve as a screening scale. The present study further confirmed cognitive deficits in iRBD as an early clinical marker in the prodromal stage of synucleinopathy.

The Gesture Imitation in Alzheimer's Disease Dementia and Amnestic Mild Cognitive Impairment.

BACKGROUND: Alzheimer's disease dementia (ADD) has become an important health problem in the world. Visuospatial deficits are considered to be an early symptom besides memory disorder. OBJECTIVES: The gesture imitation test was devised to detect ADD and amnestic mild cognitive impairment (aMCI). METHODS: A total of 117 patients with ADD, 118 with aMCI, and 95 normal controls were included in this study. All participants were administered our gesture imitation test, the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Clock Drawing Test (CDT), and the Clinical Dementia Rating Scale (CDR). RESULTS: Patients with ADD performed worse than normal controls on global scores and had a lower success rate on every item (p < 0.001). The area under the curve (AUC) for the global scores when comparing the ADD and control groups was 0.869 (p < 0.001). Item 4 was a better discriminator with a sensitivity of 84.62% and a specificity of 67.37%. The AUC for the global scores decreased to 0.621 when applied to the aMCI and control groups (p = 0.002). After controlling for age and education, the gesture imitation test scores were positively correlated with the MMSE (r = 0.637, p < 0.001), the MoCA (r = 0.572, p < 0.001), and the CDT (r = 0.514, p < 0.001) and were negatively correlated with the CDR scores (r = -0.558, p < 0.001). CONCLUSIONS: The gesture imitation test is an easy, rapid tool for detecting ADD, and is suitable for the patients suspected of mild ADD and aMCI in outpatient clinics.
