The case for diet: a safe and efficacious strategy for secondary stroke prevention

Reviving Consciousness: A Neurophysiotherapy Triumph in Decompressive Craniotomy Recovery

This case report presents a 54-year-old male with a history of type-2 diabetes mellitus who experienced sudden unconsciousness and vomiting, leading to aspiration and subsequent diagnosis of a hemorrhagic stroke. The patient underwent an immediate decompressive craniotomy, revealing a sizable intraparenchymal hematoma in the right basal ganglia and corona radiata. Postoperatively, the patient exhibited left-sided weakness, hyporeflexia, and cognitive impairment. A comprehensive neurophysiotherapy intervention addressed impaired mobility, strength, balance, coordination, respiratory complications, pain management, and other associated challenges. The rehabilitation protocol involved diverse strategies such as passive and active exercises, sensory stimulation, and the application of neurophysiotherapeutic approaches. The patient's progress was assessed using various outcome measures. Neurophysiotherapy plays a crucial role in the recovery of decompressive craniotomy.

A Smart Monitoring System for Self-Nutrition Management in Pediatric Patients with Inherited Metabolic Disorders: Maple Syrup Urine Disease (MSUD)

A metabolic disorder is due to a gene mutation that causes an enzyme deficiency which leads to metabolism problems. Maple Syrup Urine Disease (MSUD) is one of the most common and severe hereditary metabolic disorders in Saudi Arabia. Patients and families were burdened by complex and regular dietary therapy menus because of the lack of information on food labels, it was also difficult to keep track of MSUD's typical diet. The prototype smart plate system proposed in this work may help patients with MSUD and their caregivers better manage the patients' MSUD diet. The use of knowledge-based, food identification techniques and a device could provide a support tool for self-nutrition management in pediatric patients. The requirements of the system are specified by using questionaries. The design of the prototype is divided into two parts: software (mobile application) and hardware (3D model of the plate). The knowledge-based mobile application contains knowledge, databases, inference, food recognition, food plan, monitor food plan, and user interfaces. The hardware prototype is represented in a 3D model. All the patients agreed that a smart plate system connected to a mobile application could help to track and record their daily diet. A self-management application can help MSUD patients manage their diet in a way that is more pleasant, effortless, accurate, and intelligent than was previously possible with paper records. This could support dietetic professional practitioners and their patients to achieve sustainable results.

Periventricular magnetisation transfer abnormalities in early multiple sclerosis

•

Periventricular-MTR gradients are present from the earliest stage of MS and become steeper in advanced disease.

•

Lower MTR in periventricular-NAWM was positively associated with reduced cortical-mean-thickness.

•

MTR in periventricular-lesions scaled with cortical-mean-thickness, while non-periventricular lesions were unrelated.

•

These findings suggest a common pathophysiologic mechanism between CSF-adjacent cortical and periventricular areas.

Objective

Recent studies suggested that CSF-mediated factors contribute to periventricular (PV) T2-hyperintense lesion formation in multiple sclerosis (MS) and this in turn correlates with cortical damage. We thus investigated if such PV-changes are observable microstructurally in early-MS and if they correlate with cortical damage.

Methods

We assessed the magnetisation transfer ratio (MTR) in PV normal-appearing white matter (NAWM) and in MS lesions in 44 patients with a clinically isolated syndrome (CIS) suggestive of MS and 73 relapsing-remitting MS (RRMS) patients. Band-wise MTR values were related to cortical mean thickness (CMT) and compared with 49 healthy controls (HCs). For each band, MTR changes were assessed relative to the average MTR values of all HCs.

Results

Relative to HCs, PV-MTR was significantly reduced up to 2.63% in CIS and 5.37% in RRMS (p < 0.0001). The MTR decreased towards the lateral ventricles with 0.18%/mm in CIS and 0.31%/mm in RRMS patients, relative to HCs. In RRMS, MTR-values adjacent to the ventricle and in PV-lesions correlated positively with CMT and negatively with EDSS.

Conclusion

PV-MTR gradients are present from the earliest stage of MS, consistent with more pronounced microstructural WM-damage closer to the ventricles. The positive association between reduced CMT and lower MTR in PV-NAWM suggests a common pathophysiologic mechanism. Together, these findings indicate the potential use of multimodal MRI as refined marker for MS-related tissue changes.

Age-related changes to vestibular heave and pitch perception and associations with postural control

Falls are a common cause of injury in older adults (OAs), and age-related declines across the sensory systems are associated with increased falls risk. The vestibular system is particularly important for maintaining balance and supporting safe mobility, and aging has been associated with declines in vestibular end-organ functioning. However, few studies have examined potential age-related differences in vestibular perceptual sensitivities or their association with postural stability. Here we used an adaptive-staircase procedure to measure detection and discrimination thresholds in 19 healthy OAs and 18 healthy younger adults (YAs), by presenting participants with passive heave (linear up-and-down translations) and pitch (forward-backward tilt rotations) movements on a motion-platform in the dark. We also examined participants' postural stability under various standing-balance conditions. Associations among these postural measures and vestibular perceptual thresholds were further examined. Ultimately, OAs showed larger heave and pitch detection thresholds compared to YAs, and larger perceptual thresholds were associated with greater postural sway, but only in OAs. Overall, these results suggest that vestibular perceptual sensitivity declines with older age and that such declines are associated with poorer postural stability. Future studies could consider the potential applicability of these results in the development of screening tools for falls prevention in OAs.

Effects of an Avocado-based Mediterranean Diet on Serum Lipids for Secondary Prevention after Ischemic Stroke Trial (ADD-SPISE): Study protocol

BACKGROUND:

A poor or unhealthy diet is responsible for an important fraction of ischemic stroke risk. Adherence to dietary patterns, such as the Mediterranean diet, rich in monounsaturated fatty acids mainly from olive oil, is associated with a lower stroke risk. Furthermore, lowering low-density cholesterol (LDL-C) levels decreases stroke recurrence. Interestingly, Avocado-substituted diets, which are also rich in monounsaturated fatty acids, significantly decrease LDL cholesterol levels. This study aims to evaluate whether a Mediterranean diet based on Avocados reduces LDL-C compared to a low-fat high-complex carbohydrate diet after 3 months of the intervention in patients who had a recent acute ischemic stroke. The trial will also assess safety and feasibility.

PATIENTS AND METHODS:

Prospective, randomized open-label, blinded outcome assessment clinical trial. Participants are patients within a month of being admitted with an ischemic stroke, who consent and fulfil the eligibility criteria. Patients are randomly assigned to either diet intervention in a 1:1 ratio on top of the usual secondary prevention treatment. The intervention diet is: A).. Avocado-based Mediterranean diet with intake of 1/2 portion of Avocado per day and B).. The control diet is a low-fat high-complex carbohydrate diet. The main efficacy outcome is a reduction in plasma LDL-C levels at 3 months of the dietary intervention. Secondary outcomes include changes in the levels of serum lipid profile and serum inflammation markers, safety, and feasibility. A sample size of 200 patients was estimated to provide 80% power and 5% level of significance (10% loss and 5% crossover) to detect a minimum difference of 4.6 mg/dL in LDL-C after 3 months of intervention.

CONCLUSION:

We hypothesize that an Avocado-based Mediterranean diet will further reduce the levels of LDL-cholesterol at 3 months compared to the control diet, and that the intervention is safe and feasible.

The study is registered under ADDSPISE at www.clinicaltrials.gov. Identifier NCT03524742. Protocol ID CAS-605 version 3.0 (May 2nd, 2019).

Mediterranean-Dash Intervention for Neurodegenerative Delay (MIND) Diet Slows Cognitive Decline After Stroke

OBJECTIVE

This study sought to determine if the MIND diet (a hybrid of the Mediterranean and Dash diets, with modifications based on the science of nutrition and the brain), is effective in preventing cognitive decline after stroke.

DESIGN

We analyzed 106 participants of a community cohort study who had completed a diet assessment and two or more annual cognitive assessments and who also had a clinical history of stroke. Cognition in five cognitive domains was assessed using structured clinical evaluations that included a battery of 19 cognitive tests. MIND diet scores were computed using a valid food frequency questionnaire (FFQ). Dietary components of the MIND diet included whole grains, leafy greens and other vegetables, berries, beans, nuts, lean meats, fish, poultry, and olive oil and reduced consumption of cheese, butter, fried foods, and sweets. MIND diet scores were modeled in tertiles. The influence of baseline MIND score on change in a global cognitive function measure and in the five cognitive domains was assessed using linear mixed models adjusted for age and other potential confounders.

RESULTS

With adjustment for age, sex, education, APOE-ε4, caloric intake, smoking, and participation in cognitive and physical activities, the top vs lowest tertiles of MIND diet scores had a slower rate of global cognitive decline (β = .08; CI = 0.0074, 0.156) over an average of 5.9 years of follow-up.

CONCLUSIONS

High adherence to the MIND diet was associated with a slower rate of cognitive decline after stroke.

Compliance with Nutritional and Lifestyle Recommendations in 13,000 Patients with a Cardiometabolic Disease from the Nutrinet-Santé Study

BACKGROUND

A healthy diet has been shown to prevent cardiovascular diseases complications. The objective of this study was to assess dietary intakes and compliance with nutritional and lifestyle recommendations in French adults diagnosed with hypertension, diabetes, dyslipidaemia or cardiovascular disease compared with healthy individuals.

METHODS

Data was collected from 26,570 subjects aged 35 to 70 years (13,285 patients and 13,285 controls matched by sex and age) of the French cohort NutriNet-Santé. Dietary intakes were assessed using three 24-h records. Mean food and nutrient intakes of patients were compared to those of healthy subjects using multivariable mixed logistic and linear regressions.

RESULTS

Compared to healthy controls, adults reporting cardiometabolic diseases had lower intakes of sweetened products, higher intakes of fish and seafood and a better compliance with dairy products. However, overall, they reported unhealthier lifestyles and dietary habits. Indeed, they were less often physically active and had similar habits regarding alcohol and tobacco consumption. They also had lower intakes of fruit, higher intakes of meat, processed meat and added fats. It is noteworthy that diabetic subjects tended to show the highest compliance with certain dietary recommendations (vegetables, pulses and whole grain products).

CONCLUSION

Our study brings into focus the fact that some nutritional aspects still need to be improved among individuals with a cardiometabolic disease. We should encourage higher intakes of fruits and vegetables, whole grain products, and lower intakes of meat and sodium, as well as healthy lifestyle (physical activity, no-smoking and limited intake of alcohol) in order to encourage a healthier management after being diagnosed.
