This study aimed to evaluate the usefulness of the Mini Nutritional Assessment (MNA) to assess nutritional status of Iranian population and to compare its psychometric properties between patients suffering from a chronic disease, healthy elderly and younger adults. As a group of elderly with a chronic disease, 143 Parkinson's disease (PD) patients and as the control group, 467 healthy persons were enrolled. The Persian-translated version of MNA was filled-up through interviews together with anthropometric measurements. Cronbach's α coefficient of entire MNA was 0.66 and 0.70 in healthy individuals and PD patients, respectively. The total MNA score could significantly discriminate the ones with BMI ≥ 24kg/m(2) in both groups. In general, MNA was a valid and reliable tool for nutritional assessment. We acknowledge study limitations including lack of serum measurements and a selection bias towards mild-to-moderate PD. MNA is a more reliable tool in older healthy individuals and rather younger elderly with PD.
Background: The magnitude of malnutrition in the Parkinson's disease (PD) population has yet to be accurately quantified. Objective: We aimed to estimate and compare the prevalence of malnourished and those at risk of malnutrition in Iranian PD patients with a matched control group using the mini nutritional assessment (MNA) and anthropometric measurements. Methods: Nutritional status was evaluated in 143 Iranian PD patients (case group) and 145 age-and sex-matched healthy controls (control group) using the validated Persian version of the MNA. Individuals suffering from chronic comorbidities influencing nutritional state (hypertension and diabetes), following special diets and those with cognitive impairment were excluded. Using the MNA, a total score of <17 indicated malnutrition and scores of 17-23.5 signified cases at risk for malnutrition. Results: The mean of total MNA score was not significantly different between two study groups [24.4 (SD = 3.8) in controls vs. 25.1 (SD = 3.4) in PD patients; P = 0.094]. Three (2.1%) PD patients were suffering from malnutrition and another 37 (25.9%) were at risk of malnutrition; while in control group similar feature was observed (2.0% malnourished and 35.2% at risk of malnutrition; P = 0.228). The mean of calf circumference (CC) was significantly lower in PD patients [34.9 (SD = 3.8) cm vs. 36.0 (SD = 5.1) cm; P = 0.046]. Conclusions: Our findings indicate the same nutritional status among mild to moderate PD patients compared with healthy controls. However, more than a quarter of the PD population was found to be at risk of malnutrition necessitating more attention towards nutritional assessment in PD.
Purpose:
To review various types of extraocular muscle transposition procedures for management of strabismus in sixth cranial nerve palsy with little lateral rectus (LR) muscle function, along with their pros and cons.
Methods:
We performed a comprehensive review of transposition procedures in sixth cranial nerve palsy, based on literature published anytime up to March 2021. A thorough search through PubMed and Cochrane databases was performed. All types of clinical studies on different transposition procedures in LR palsy, were included.
Results:
Eighty-six original articles in English, with full text or abstracts available, were included in the review, among which 16 are prospective studies, 48 retrospective, 3 review articles, 1 randomized clinical trial, 17 case reports, and 1 letter. Vertical rectus transposition has demonstrated promising results, especially in abduction improvement and expansion of binocular diplopia-free visual field, albeit the possible adverse effects such as anterior segment ischemia, especially in the presence of medial rectus contracture, and induced vertical deviation may become troublesome. Partial muscle transposition, single muscle transposition, and also transposition without tenotomy have all been introduced to reduce the risk of multiple muscle manipulation and ischemia. On the other hand, different adjustable transpositions are being utilized to manage concomitant or induced vertical deviations.
Conclusion:
Transposition procedures are highly effective in the treatment of esotropia caused by complete LR palsy. Various techniques for vertical muscle transposition have been proposed, with each of them having certain advantages and disadvantages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
