RESUMO

Deformational plagiocephaly, deformational brachycephaly, and deformational scaphocephaly are the most common types of skull deformities during the first year of life. Using a cranial remolding orthosis (CRO) can have an important role in achieving a satisfactory level of improvement in symmetry and proportion of the deformed skulls. However, there is no consensus on the most important parameters for the success or length of treatment with a CRO. In this study, we did a systematic literature review in PubMed, Scopus, Web of Science, and EMBASE on January 2023. Titles/abstracts of the found studies were screened by two independent reviewers. The Newcastle-Ottawa Scale was used to evaluate the quality of the included articles. The best evidence synthesis was considered to determine the strength of the reported factors. A total of 25 articles with an accumulated sample of 7594 participants were included. Nine predictive factors, including age at initiation of CRO treatment, CRO compliance, deformity severity, deformity type, torticollis, gestational age, gestational type, delivery method, and developmental delay, were considered for CRO treatment length or success. Moderate evidence suggests that CRO treatment length is linked to a patient's age at the start of treatment and the deformity severity. Moreover, treatment success is correlated with a patient's age at the start of treatment, CRO compliance, and deformity severity. Moderate evidence indicates that there is no relationship between the presence of torticollis and gestational age with CRO treatment success.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has caused widespread devastation, with millions of confirmed cases and deaths worldwide. Although there were efforts made to develop treatments and vaccines for COVID-19, the coexistence of sarcopenia, a muscle disorder, has been largely overlooked. It is while new variants of this disease (eg, BA.2.86) are challenging the current protocols. Sarcopenia is associated with increased mortality and disability, and shares common mechanisms with COVID-19, such as inflammation, hormonal changes, and malnutrition. This can worsen the effects of both conditions. Furthermore, survived patients with COVID-19 who have elevated risk, as well as aging, which increases the process of sarcopenia. Therefore, addressing sarcopenia in patients with COVID-19 and surviving individuals can be crucial for improving outcomes and preventing long-term disability. During hospital stays, assessing sarcopenia through indicators like muscle wasting and malnutrition is important. Nutritional interventions, such as malnutrition screening and enteral feeding, play a critical role in preventing sarcopenia in hospitals. Mental health and physical activity evaluations and interventions are also necessary. Even after recovering from COVID-19, there is a risk of developing sarcopenia, requiring continued monitoring. Nutrition and physical activity considerations are vital for prevention and management, necessitating tailored training programs and diet therapy. Mental health should not be overlooked, with regular screening, and community-based interventions. Infrastructure should support physical activity, and mental health services must become more accessible. Community engagement through support groups and peer networks can foster resilience and social connection. Efforts are needed to promote healthy diets and ensure access to nutritious foods.

RESUMO

BACKGROUND: Retinal degenerative disorders (RDDs) cause vision loss by damaging retinal neurons and photoreceptors, affecting individuals of all ages. Cell-based therapy has emerged as an effective approach for the treatment of RDDs with promising results. This meta-analysis aims to comprehensively evaluate the efficacy of cell therapy in treating age-related macular degeneration (AMD), retinitis pigmentosa (RP), and Stargardt macular degeneration (SMD) as the most prevalent RDDs. METHODS: PubMed, Scopus, Web of Science, and Embase were searched using keywords related to various retinal diseases and cell therapy treatments until November 25th, 2023. The studies' quality was evaluated using the Joanna Briggs Institute's (JBI) checklist for quasi-experimental studies. Visual acuity measured as LogMAR score was used as our main outcome. A three-level random-effect meta-analysis was used to explore the visual acuity in patients who received cell-based therapy. Heterogeneity among the included studies was evaluated using subgroup and sensitivity analyses. Moreover, meta-regression for the type of cells, year of publication, and mean age of participants were performed. RESULTS: Overall, 8345 studies were retrieved by the search, and 39 met the eligibility criteria, out of which 18 studies with a total of 224 eyes were included in the meta-analysis. There were 12 studies conducted on AMD, 7 on SMD, and 2 on RP. Cell therapy for AMD showed significant improvement in LogMAR (p < 0.05). Also, cell therapy decreased the LogMAR score in SMD and RP (p < 0.01 and p < 0.0001, respectively). Across all conditions, no substantial publication bias was detected (p < 0.05). CONCLUSION: The findings of the study highlight that the application of cell therapy can enhance the visual acuity in AMD, SMD, and RP.

RESUMO

BACKGROUND: Follow-up of COVID-19 recovered patients to discover important adverse effects on other organs is required. The psychological health of COVID-19 patients may be affected after recovery. AIM: We aimed to evaluate the association between adherence to the Nordic diet (ND) and psychological symptoms caused by COVID-19 after recovery. METHOD: Dietary data on 246 qualified adults (123 cases and 123 controls). The dietary intake in this case-control study was calculated by a reliable and valid food frequency questionnaire (FFQ). Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Short-Form Health Survey (SF-36) were used to analyze participant's anxiety, stress, depression, sleep quality, insomnia, and quality of life of participants. RESULTS: There was a significant inverse relationship between total anxiety, stress, and depression scores and the intake of whole grains (P < 0.05). Furthermore, there was a significant inverse association between depression and fruit intake (P < 0.05). A significant negative correlation was found between insomnia and sleep quality and the intake of root vegetables (P < 0.05). In the multinomial-regression model, a significant association between the Nordic diet and anxiety, stress, and depression was found only in the case group (OR = 0.719, 95% CI 0.563-0.918, p-value = 0.008; OR = 0.755, 95% CI 0.609-0.934, P-value = 0.010, and, OR = 0.759, 95% CI 0.602-0.956, P-value = 0.019 respectively). CONCLUSION: Adherence to the Nordic diet might reduce anxiety, stress, and depression in recovered COVID-19 patients.

RESUMO

Adipose tissue, as an endocrine organ, secretes several adipocyte-derived hormones named 'adipokines' that are implicated in regulating energy haemostasis. Substantial evidence shows that white adipose tissue-derived adipokines mediate the link between obesity-related exogenous factors (like diet and lifestyle) and various biological events (such as pre- and postmenopausal status) that have obesity consequences (cardiometabolic disorders). One of the critical aetiological factors for obesity-related diseases is the dysfunction of adipokine pathways. Acylation-stimulating protein (ASP) is an adipokine that stimulates triglyceride synthesis and storage in adipose tissue by enhancing glucose and fatty acid uptake. ASP acts via its receptor C5L2. The primary objective of this review is to address the existing gap in the literature regarding ASP by investigating its diverse responses and receptor interactions across multiple determinants of obesity. These determinants include diet composition, metabolic disorders, organ involvement, sex and sex hormone levels. Furthermore, this article explores the broader paradigm shift from solely focusing on adipose tissue mass, which contributes to obesity, to considering the broader implications of adipose tissue function. Additionally, we raise a critical question concerning the clinical relevance of the insights gained from this review, both in terms of potential therapeutic interventions targeting ASP and in the context of preventing obesity-related conditions, highlighting the potential of the ASP-C5L2 interaction as a pharmacological target. In conclusion, these findings validate that obesity is a low-grade inflammatory status with multiorgan involvement and sex differences, demonstrating dynamic interactions between immune and metabolic response determinants.

RESUMO

Background: Total knee arthroplasty (TKA) is among the most frequent orthopedic procedures. TKA has been shown to provide significant benefits to patients with rheumatoid arthritis (RA) and osteoarthritis (OA). We hypothesized that patients undergoing primary TKA with diverse preoperative diseases would have varying expectations for both pain and function following TKA. Materials and Methods: Patients diagnosed with OA or RA participated in this prospective cohort investigation. We assessed variables including Knee society score (KSS), and patient's quality of life using 36-Item Short Form Survey Instrument (SF-36). Pain was also measured using the Visual Analogue Scale (VAS). Results: In this study, 606 patients including 412 females and 194 males with a mean age of 65.5 ± 8.7 years were included in the study. Among patients, 46 patients underwent TKA due to RA and 560 patients due to knee OA. There was no statistically significant difference in term of KSS clinical score before the operation (P = 0.101). The mean of KSS clinical score and functional score variables at 6 months and 12 months after the operation were higher in OA group in comparison to RA group. SF-36 was significantly improved in OA group in comparison to RA group. Also, VAS in the RA group is significantly higher than in the OA group after 12 months of follow-up. Conclusion: Our results demonstrate that patients with OA after TKA have better KSS clinical and functional results than patients with RA.

RESUMO

Mental health disorders are linked to systemic inflammation. Due to high inflammation and mental health disorders in COVID-19 patients, we aimed to investigate the relationship between blood inflammatory markers such as red cell distribution width to platelet ratio (RPR), platelet-lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), red cell distribution width (RDW), white blood cell (WBC), and psychological function in COVID-19 patients. In the current cross-sectional study, neuro-psychological function, and a complete blood count (CBC) were measured on 120 COVID-19 patients aged >30 years from the Imam Reza Hospital in Mashhad, Iran. Our results showed that anxiety related to MCHC (mean ± SD: 32.71 ± 1.68, p < 0.05), WBC (mean ± SD: 12.23 ± 5.43, p < 0.05), and PLR (median (IQR): 28.72 (15.88-41.31), p < 0.05) significantly. In the stress subgroup, only RPR was associated with stress (p < 0.05). Linear regression between hematological parameters and psychological score indicated that RDW and PLR had a significantly positive association with depression (ß = 0.086; p = 0.045 and ß = 1.326; p = 0.016, respectively) and anxiety scores (ß = 0.100; p = 0.038 and ß = 1.356; p = 0.010, respectively). Moreover, a positive correlation was found between PLR and stress (ß = 1.102; p = 0.012). This study showed a positive association between depression/anxiety/stress symptoms and levels of hematological inflammatory markers including PLR and RDW. The findings of this study provide novel insights into mental health and physiological markers, underscoring the potential influence of inflammation on mood disorders. Our findings offer exciting prospects for future research and may lead to innovative approaches in the management and treatment of depression, anxiety, and stress.

RESUMO

Objectives: This study aims to identify a new barrier to the use of the Mini-Nutrition Assessment Short-Form (MNA-SF), which is a malnutrition assessment tool for the risk assessment of sarcopenia in a nourished population. Methods: The MNA-SF was completed, and individuals with a score of > 11 were considered nourished in this cross-sectional feasibility study of a registry. Sarcopenia was assessed in 766 healthy, nourished adults (33.4% men, 64.9 ± 7.1 years) based on the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Results: The MNA-SF scores for non-sarcopenia, pre-, confirmed, and severe sarcopenia were 13.59 ± 0.69, 13.73 ± 0.60, 12.64 ± 0.74, and 12.5 ± 0.71, respectively. The higher MNA-SF score association with pre-sarcopenia [odds ratio (OR): 1.41, 95% confidence interval (CI): 1.06-1.86, P = 0.02], confirmed sarcopenia (OR = 0.25, 95% CI: 0.13-0.49, P < 0.001), and severe sarcopenia (OR = 0.20, 95% CI: 0.09-0.46, P < 0.001) was as significant as in the MNA-SF categories. Individuals with a score = 13 (compared with 14), had a higher risk of confirmed sarcopenia (OR = 10.07, 95% CI: 1.92-52.71, P = 006) and severe sarcopenia (OR = 12.09, 95% CI: 1.24-117.50, P = 0.032). Individuals with a score of 12 had a higher risk of confirmed sarcopenia (OR = 30.94, 95% CI: 4.25-103.02, P < 0.001) and severe sarcopenia (OR = 35.90, 95% CI: 4.25-303.07, P = 0.001) compared with subjects with a score of 14. The models also showed that MNA-SF < 13 could predict sarcopenia. Conclusion: There was a significant association between MNA-SF and confirmed and severe sarcopenia in nourished people. Sarcopenia assessment in people with MNA-SF < 13 can be beneficial. Developing a tool to identify the risk of malnutrition and sarcopenia at the same time based on MNA-SF can be considered.

RESUMO

miRNAs represent appropriate candidates for treatment of several disorders. However, safe and efficient delivery of these small-sized transcripts has been challenging. Nanoparticle-based delivery of miRNAs has been used for treatment of a variety of disorders, particularly cancers as well as ischemic stroke and pulmonary fibrosis. The wide range application of this type of therapy is based on the important roles of miRNAs in the regulation of cell behavior in physiological and pathological conditions. Besides, the ability of miRNAs to inhibit or increase expression of several genes gives them the superiority over mRNA or siRNA-based therapies. Preparation of nanoparticles for miRNA delivery is mainly achieved through using protocols originally developed for drugs or other types of biomolecules. In brief, nanoparticle-based delivery of miRNAs is regarded as a solution for overcoming all challenges in the therapeutic application of miRNAs. Herein, we provide an overview of studies which used nanoparticles as delivery systems for facilitation of miRNAs entry into target cells for the therapeutic purposes. However, our knowledge about miRNA-loaded nanoparticles is limited, and it is expected that numerous therapeutic possibilities will be revealed for miRNA-loaded nanoparticles in future.

RESUMO

Background: Lifestyle modifications have been recommended as an essential treatment approach for cardiovascular diseases. Recent studies have shown that eating frequency (EF) correlates with hypertension and related risk of organ damage. This study aimed to examine critical clinical implications to evaluate the association of EF with arterial stiffness parameters as an early marker of atherosclerosis manifestations. Methods: A cross-sectional descriptive study was performed on 658 participants of the PERSIAN Organizational Cohort study in Mashhad, aged 30–70 years. Arterial stiffness was assessed by measurement markers of arteriosclerosis, including arterial age, augmentation index (AIx), augmentation pressure (AP), carotid-femoral pulse wave velocity (Cf-PWV), and central blood pressure. Differences in anthropometric indices, blood indices, and arterial stiffness parameters were evaluated across EF groups. Results: Our data demonstrate that EF was positively correlated with total daily energy intake, and favourable profiles of adiposity and blood lipids. Subjects with an increased EF, had significantly lower AIx, AP, Arterial Age and Central blood pressure (P for trend<0.001) as compared to Lowest EF and not significant with PWV (P for trend, 0.19). Arterial stiffness was also significantly lower in those with increased EF compared with subjects with low EF. By Linear regression analysis, after adjustment for Confounding factors, except PWV, EF showed the associations with all of the non-invasive arterial stiffness parameters. Conclusion: Increased EF is associated with a lower wave reflection and blood pressure in the central arteries.(AU)


Introducción: Las modificaciones del estilo de vida se han recomendado como un enfoque de tratamiento esencial para las enfermedades cardiovasculares. Estudios recientes han demostrado que la frecuencia de las comidas (EF) se correlaciona con la hipertensión y el riesgo relacionado de daño orgánico. Este estudio tenía como objetivo examinar las implicaciones clínicas críticas para evaluar la asociación de la EF con los parámetros de rigidez arterial como un marcador temprano de las manifestaciones de la aterosclerosis. Métodos: Se realizó un estudio descriptivo transversal en 658 participantes del estudio de cohorte organizativo PERSIAN en Mashhad, de entre 30 y 70 años de edad. La rigidez arterial se evaluó mediante la medición de marcadores de arteriosclerosis, incluyendo la edad arterial, el índice de aumento (AIx), la presión de aumento (AP), la velocidad de la onda del pulso carótido-femoral (Cf-PWV) y la presión arterial central. Se evaluaron las diferencias en los índices antropométricos, los índices sanguíneos y los parámetros de rigidez arterial en los grupos de EF. Resultados: Nuestros datos demuestran que la EF se correlacionó positivamente con la ingesta energética diaria total, los perfiles favorables de adiposidad y los lípidos sanguíneos. Los sujetos con una EF aumentada, tenían un AIx, una AP, una edad arterial y una presión arterial central significativamente menores (p de tendencia <0,001) en comparación con la EF más baja y no significativa con la PWV (p de tendencia, 0,19). La rigidez arterial también fue significativamente menor en los sujetos con una mayor FE en comparación con los sujetos con una FE baja. Mediante un análisis de regresión lineal, después de ajustar los factores de confusión, excepto la VOP, la frecuencia de las comidas se asoció con todos los parámetros de rigidez arterial no invasivos. Conclusiones: El aumento de la FE se asocia a una menor reflexión de la onda y a una menor presión arterial en las arterias...(AU)

RESUMO

Introduction: Gastric bypass surgery is a gold standard therapy for severe obesity. This study aimed to evaluate anthropometric predictors for short-term excess weight loss (EWL) after Roux-en-Y gastric bypass surgery (RYGB) in a sample of severely obese patients. Materials and Methods: This cohort study was conducted on severely obese candidates for RYGB bariatric surgery in Mashhad, Iran. Indirect calorimetry, anthropometric measurements, and body composition data were collected before, one, and six months after RYGB. Results: Fifty-four participants (43, 79.6% women and 11, 20.4% men) with a mean age of 39.63 ± 9.66 years participated in this study. The mean total weight and BMI loss within six months were 32.89 ± 20.22 kg and 12.37 ± 7.34 kg/m2, respectively. The mean reduction in adipose tissue and fat-free mass was 24.49 kg and 7.46 kg, respectively. The mean resting metabolism rate (RMR) reduction at one and six months after RYGB was 260.49 kcal and 396.07 kcal, respectively. There was a significant difference in mean RMR between the baseline and one and six months after RYGB (p < 0.001). There was no significant gender difference in mean weight and BMI loss percentage at six months post-RYGB (p > 0.05). Baseline skeletal muscle mass (SMM), excess BMI loss (EBMIL) at first month after surgery, and baseline neck circumference (NC) could predict EWL six months after surgery. Conclusion: Reduced RMR shortly after RYGB may be due to FFM reduction. Some anthropometric and their acute changes after RYGB may predict the short-term EWL in RYGB patients.

RESUMO

The demands for alternative energy have led researchers to find effective electrocatalysts in fuel cells and increase the efficiency of existing materials. This study presents new nanocatalysts based on two binary transition metal oxides (BTMOs) and their hybrid with reduced graphene oxide for methanol oxidation. Characterization of the introduced three-component composite, including cobalt manganese oxide (MnCo2O4), nickel cobalt oxide (NiCo2O4), and reduced graphene oxide (rGO) in the form of MnCo2O4/NiCo2O4/rGO (MNR), was investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), and energy-dispersive X-ray (EDX) analyses. The alcohol oxidation capability of MnCo2O4/NiCo2O4 (MN) and MNR was evaluated in the methanol oxidation reaction (MOR) process. The crucial role of rGO in improving the electrocatalytic properties of catalysts stems from its large active surface area and high electrical conductivity. The alcohol oxidation tests of MN and MNR showed an adequate ability to oxidize methanol. The better performance of MNR was due to the synergistic effect of MnCo2O4/NiCo2O4 and rGO. MN and MNR nanocatalysts, with a maximum current density of 14.58 and 24.76 mA/cm2 and overvoltage of 0.6 and 0.58 V, as well as cyclic stability of 98.3% and 99.7% (at optimal methanol concentration/scan rate of 20 mV/S), respectively, can be promising and inexpensive options in the field of efficient nanocatalysts for use in methanol fuel cell anodes.

RESUMO

Purpose: In people with diabetes, one of the problems for patients is muscle wasting and inhibition of the protein synthesis pathway. This study aimed to evaluate the effects of HIIT on protein expression in two skeletal muscles, flexor hallucis longus (FHL) and soleus (SOL) in rats with type 2 diabetes mellitus (T2DM). Materials and methods: Diabetes initially was induced by streptozotocin (STZ) and nicotinamide. Rats with type 2 diabetes were randomly and equally divided into control (n = 6) and HIIT groups (n = 6). After 8 weeks of training, the content of total and phosphorylated proteins of serine/threonine-protein kinases (AKT1), mammalian target of rapamycin (mTOR), P70 ribosomal protein S6 kinase 1 (P70S6K1), and 4E (eIF4E)-binding protein 1 (4E-BP1) in FHL and SOL muscles were measured by Western blotting. While body weight and blood glucose were also controlled. Results: In the HIIT training group, compared to the control group, a significant increase in the content of AKT1 (0.003) and mTOR (0.001) proteins was observed in the FHL muscle. Also, after 8 weeks of HIIT training, protein 4E-BP1 (0.001) was increased in SOL muscle. However, there was no significant change in other proteins in FHL and SOL muscle. Conclusions: In rats with type 2 diabetes appear to HIIT leading to more protein expression of fast-twitch muscles than slow-twitch muscles. thus likely HIIT exercises can be an important approach to increase protein synthesis and prevent muscle atrophy in people with type 2 diabetes.

RESUMO

Background: Some studies have shown that Socioeconomic Status (SES) is positively related to insulin resistance among different population groups, except for pregnant women. Therefore, we examined the relationship between SES and Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) index as well as mediating variables. Materials and Methods: This study was performed on 138 primiparous healthy women at 6-10 weeks of pregnancy. The association between SES and HOMA-IR was analyzed by regression analysis, and mediating variables were determined by mediation analysis. Results: SES score was positively correlated with HOMA-IR index [ß = 0.02, t101 = 2.20, p = 0.03, 95% CI: (0.00-0.05]. The higher percentage of mediation was related to maternal weigh (70.80%). Job activity had a protective effect on the association between SES and HOMA-IR (-62.50%). The total percentage of two mediators was 25%. Conclusions: The positive relationship between SES and (HOMA-IR) in early pregnancy may provide a way to control this condition.

RESUMO

Introduction: Low serum vitamin D has been shown to be a risk factor for Coronavirus 2019 (COVID-19). The aim of this study was to assess the effects of high dose vitamin D supplementation on hs-CRP, ESR and clinical outcomes, including duration of hospitalization, quality of life and New York Heart Association (NYHA) Functional Classification, in adults with COVID-19. Methods: This double-blind, randomized control trial will be conducted on patients with RT-PCR and/or chest CT scan diagnosis of COVID-19 admitted in Imam Reza Hospital, Mashhad, Iran. Participants will be randomized into control and intervention groups based on randomization sampling. The intervention group will receive soft gel containing 50,000 IU vitamin D on the first day followed by 10,000 IU/day through a supplement drop daily for 29 days. The control group will receive 1000 IU vitamin D daily through supplement drop and a placebo soft gel. All participants will undergo laboratory assessment including inflammatory markers, serum 25)OH)D, complete blood count (CBC), liver and renal profile, lipid profile and erythrocyte sedimentation rate (ESR) at baseline and at day 30. The mortality rate will be recorded in both groups. Results: Data will be presented using descriptive statistics. Comparison of changes in study parameters over the study period will be performed using analysis of covariance adjusting for possible confounders. Conclusions: The findings of this will provide evidence on the effects of high dose vitamin D supplementation on inflammatory markers in hospitalized COVID-19 patients.

RESUMO

BACKGROUND AND AIM: Primary Ovarian Insufficiency (POI) is defined by the occurrence of menopause before the age of 40 years. It is often associated with cardiovascular disease (CVD). The purpose of this study was to explore the relationship between POI-associated genotypes cardiometabolic disorder risk factors. METHODS: One hundred seventeen women with POI and one hundred eighty-three healthy women without POI were recruited in this study. DNA was extracted and analyzed using ASO-PCR or Tetra ARMS-PCR. Lipid profiles were also assessed. RESULTS: Multivariate logistic regression analysis showed that individuals with GG vs. TT genotype of the rs1046089 SNP were more likely to have a higher serum LDL (p = 0.03) compared to the control group. There was also a significant association between low serum HDL and rs2303369 and rs4806660 SNP genotypes in the POI group. In the POI group, the percentage of those with high total cholesterol was lower in those with a CC genotype compared to those with a TT genotype (p = 0.03). CONCLUSION: Some SNPs reported to be associated with POI appear to be independently associated with dyslipidemia. These results may be helpful to identify subjects with POI who may be susceptible to CVD.

RESUMO

Background: Swallowing is one of the most complex functions of the central nervous system (CNS), which is controlled by different parts of the brain. Oropharyngeal dysphagia (OD) is one of the most common complications after stroke. Despite a variety of behavioral, compensatory, and rehabilitative methods, many stroke patients still suffer from swallowing disorders that adversely affect their quality of life (QOL). The aim of this study was to evaluate the effect of pyridostigmine on patients with post-stroke dysphagia. Methods: A randomized, double-blind, placebo-controlled clinical trial was carried out on 40 patients suffering from post-stroke dysphagia. Patients were assigned randomly into two groups: intervention and control groups (20 in each group). The intervention group was treated with pyridostigmine (60 mg, three times a day, 30 minutes before each meal for three weeks), and the control group received placebo treatment in the same way. All patients (intervention and control) were evaluated according to National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), and Functional Communication Measures (FCM)/American Speech-Language-Hearing Association (ASHA) criteria at baseline and after three weeks of intervention. Values of P < 0.05 were considered statistically significant. Results: In the intervention group, the mean values of NIHSS, mRS, and ASHA/FCM were significantly reduced following three weeks of treatment with pyridostigmine (P = 0.002, P = 0.003, and P < 0.001, respectively), but no significant differences were found in the mean NIHSS, mRS, and ASHA/FCM in the placebo group. Conclusion: Although pyridogestamine is somewhat effective in post-stroke dysphagia, it has not been shown to be more important in preventing aspiration pneumonia and length of hospital stay.

RESUMO

The present study aimed to assess the relative validity and reliability of a modified Food and Nutrition Literacy (M-FNLIT) questionnaire in primary school children in the city of Mashhad. The study was conducted in four phases. In the first step, the content and face validity of the questionnaire were evaluated by Delphi consensus as well as interviewing the students. Then, construct validity was examined using Confirmatory Factor Analysis (CFA). The internal consistency and reliability of the questionnaire were also assessed using Cronbach α and Intraclass Correlation Coefficient (ICC), respectively. Finally, a receiver operating characteristic analysis was performed to detect the cut-off scores of the M-FNLIT scale. Findings of two rounds of Delphi showed satisfactory levels of Content Validity Ratio: 0·72 and 0·92, Content Validity Index (CVI): 0·92 and 0·98, respectively. The results of CFA for domains and subscales of the M-FNLIT questionnaire including cognitive domain (understanding food and nutrition information and nutritional health knowledge) and skill domain (functional, food choice, interactive, and critical skills) indicated acceptable fit indices. M-FNLIT subscale-specific Cronbach α values ranged between 0·68 and 0·8 and ICC was 0·95 (95 % CI 0·93, 96). The final questionnaire included forty items (thirty-six Likert-type and four true-false items). FNLIT scores were categorized as low (≤ 58), medium (> 58­< 81), and high (≥ 81). The M-FNLIT questionnaire has a good level of validity and reliability to measure food and nutrition literacy in primary school children. The questionnaire can be applied in the evaluation of nutritional interventions in this age group.
