Weight loss and weight gain in Parkinson disease

IntroductionParkinson disease (PD) has been associated with both weight loss and gain in different stages of the disease. Our study aimed to determine the prevalence and associations with weight change over two years based on 3% and 5% weight change.MethodsIn this longitudinal analysis, weight at baseline and follow-up was used to classify patients into groups of weight loss, stable, and weight gain. Differences between these groups at baseline and then with change over time were tested.ResultsThe sample was 668 patients with mean(SD) age 66.1(10) and disease duration 5.3(5.4) years. Using 3% weight change criteria: 32.6% lost, 23.1% gained, and 55.7% had stable weight. Using 5% criteria: 22.6% lost, 15.7% gained, and 61.7% had stable weight. Age was associated with both 3% and 5% change in weight. Other associations with 5% weight change were disease duration, Total and Motor Unified Parkinson's Disease Rating Scale, Older Americans Resource and Services disability, and Hoehn & Yahr staging. The effects of 3% weight loss on Motor UPDRS, IADLs, and depression, and the effects of 5% weight loss on IADLs remained statistically significant when controlling for baseline differences in age, levodopa use, and Total UPDRS.ConclusionPD patients are more likely to experience 3% than 5% weight change and this lower threshold of weight change was associated with greater disease severity and disability over time. Attention to more subtle weight change may help identify those at greater risk of disability.     

吡咯生物碱相关肝窦阻塞综合征发病机制的研究进展

吡咯生物碱诱导的肝窦阻塞综合征主要原因为摄入了含吡咯生物碱的中草药或食品。从药物因素、宿主因素、影响因素三个方面,回顾了近年来吡咯生物碱及其代谢产物参与疾病发生发展机制的研究进展。认为吡咯生物碱相关肝窦阻塞综合征的发病机制复杂、影响因素较多,部分患者预后较差,且发病机制尚未十分明确,有必要进一步深入研究。     

The effectiveness of specialized nursing interventions for patients with Parkinson disease: A randomized controlled study protocol

Background:The purpose of this experiment is to evaluate the impact of the care of Parkinson disease nurse specialist on improving motor symptoms and life quality for patients with Parkinson disease (PD).Method:This is a randomized controlled research, and it will be conducted from April 2021 to October 2021 at Sichuan Provincial People''s Hospital. The experiment was granted through the Research Ethics Committee of Sichuan Provincial People''s Hospital (004510293). All the patients suffer from PD, age 18 years or older, both female and male, regardless of the duration or severity of this disease are eligible. The exclusion criteria contains: lack sufficient knowledge to complete questionnaires, serious physical comorbidities or refuse to take part in the program. In our experiment, the major result measures are motor symptoms and life quality. For the measurement of life quality, we will utilize Parkinson disease Questionnaire-39, the most extensively utilized the scale of life quality in PD. The evaluation of motor symptoms severity is carried out with the revision of Unified Parkinson Disease Rating Scale sponsored by Movement Disorder Society.Results:Table 1 indicates clinical outcomes at different time points.Conclusion:The Parkinson''s disease nurse specialist care may promote the life quality in the PD patients.Trial registration number:researchregistry 6284.     

Very fast-progressive pulmonary opacities and high inflammatory factors levels are associated with decease of young Coronavirus Disease 2019 patients

We aimed to retrospectively analyze the clinical and computed tomography (CT) characteristics of young adults with Coronavirus Disease 2019 (COVID-19) pneumonia who were critically ill and to identify the features associated with non-survival.Thirty-eight COVID-19 patients (20–45 years old, 28 men) who had been admitted in the intensive care unit were included, including 18 non-survivors (group 1) and 20 survivors (group 2). Their clinical characteristics and initial and follow-up CT were compared between groups.In group 1, the days from illness onset to death were 21.1 ± 10.3 days; 7 patients had underlying comorbidities. At admission, group 1 exhibited higher serum ferritin and interleukin-6 (IL-6) levels (1142.6 ± 242.4 mg/L and 33.8 ± 18.6 mmol/L) compared with group 2 (728.3 ± 150.9 mg/L and 15.2 ± 6.9 mmol/L, P < .01). Group 1 exhibited more rapidly progressive opacities and consolidation in follow-up CT (16.7 ± 3.1 scores, 15.7 ± 3.1 segments) than group 2 (11.4 ± 4.0 scores, 10.3 ± 4.6 segments, P < .01). The oxygenation index was lower (87.6 ± 19.2 vs 99.1 ± 20.4 mm Hg) and the mechanical ventilation duration was longer (14.7 ± 6.9 vs 9.7 ± 3.7 days) in group 1 compare with group 2 (P < .01).Compared with the survivors, the non-survivors showed higher serum ferritin and IL-6 levels, more rapidly progressive opacities in CT, lower oxygenation index, and longer mechanical ventilation durations. Special attention to ferritin/IL-6 levels and oxygenation index as well as early CT application and timely reexaminations are important to identify the individuals who may be at risk of becoming critically ill.     

Motor dysfunction in mild cognitive impairment as tested by kinematic analysis and transcranial magnetic stimulation

ObjectivePrevious studies have demonstrated voluntary movement alterations as well as motor cortex excitability and plasticity changes in patients with mild cognitive impairment (MCI). To investigate the pathophysiology of movement abnormalities in MCI, we tested possible relationships between movement abnormalities and primary motor cortex alterations in patients.MethodsFourteen amnestic MCI (aMCI) patients and 16 healthy controls were studied. Cognitive assessment was performed using clinical scales. Finger tapping was recorded by a motion analysis system. Transcranial magnetic stimulation was used to test the input/output curve of motor evoked potentials, intracortical inhibition, and short-latency afferent inhibition. Primary motor cortex plasticity was probed by theta burst stimulation. We investigated correlations between movement abnormalities, clinical scores, and cortical neurophysiological parameters.ResultsMCI patients showed less rhythmic movement but no other movement abnormalities. Cortical excitability measures were normal in patients, whereas plasticity was reduced. Movement rhythm abnormalities correlated with frontal dysfunction scores.ConclusionOur study in MCI patients demonstrated abnormal voluntary movement and plasticity changes, with no correlation between the two. Altered rhythm correlated with frontal dysfunction.SignificanceOur results contribute to the understanding of pathophysiological mechanisms of motor impairment in MCI.     

Identification of two pathogenic mutations in SORL1 in early-onset Alzheimer’s disease

The sortilin-related receptor 1 (SORL1) gene has been the subject of many studies focusing on frequent polymorphisms, which is associated with increased risk for Alzheimer’s Disease (AD). By whole-exome sequencing (WES), we identified two pathogenic missense mutations c.579C > G (p.F193L) and c.1397A > G (p.N466S) in SORL1. The two mutations were located in the same protein domain, and the two unrelated probands both had an onset of memory problems at less than 65 years of age, but their clinical manifestations and cranial imaging are different. The protein structure and function affected by these mutations were predicted using bioinformatics analysis, which suggested they were pathogenic. 3D protein structural analysis revealed that these amino acid substitutions might result in instability of protein structure and adverse intramolecular interactions. These findings suggest that both F193L and N466S should be thought as potential causative mutations in early-onset Alzheimer’s disease (EOAD) patients. Further functional studies are warranted to evaluate their roles in the pathogenesis of AD.
