RESUMO
INTRODUCTION: Amyotrophic lateral sclerosis (ALS) produces alterations in the autonomic nervous system (ANS), which explains the cardiac manifestations observed in patients. The assessment of heart rate variability (HRV) is what best reflects the activity of the ANS on heart rate. The Polar H7 Bluetooth® device proves to be a non-invasive and much faster technology than existing alternatives for this purpose. OBJECTIVE: The goal of this study is to determine HRV using Polar H7 Bluetooth technology in ALS patients, comparing the obtained measurements with values from healthy individuals. METHOD: The sample consisted of 124 participants: 68 diagnosed with ALS and 56 healthy individuals. Using Polar H7 Bluetooth technology and the ELITE HRV application, various HRV measurements were determined for all participants, specifically the HRV index, RMSSD, RMSSD LN, SDNN index, PNN50, LF, HF, LF/HF ratio, HR average, and HF peak frequency. RESULTS: Statistically significant differences were observed between ALS patients and healthy individuals in the HRV index, RMSSD, RMSSD LN, SDNN index, PNN50, HF, and LF, where healthy individuals exhibited higher scores. For the HR average, the ALS group showed a higher value. Values were similar when comparing men and women with ALS, with only a higher HF peak frequency observed in women. CONCLUSION: The Polar H7 Bluetooth® device is effective in determining heart rate variability alterations in ALS, being a promising prognostic tool for the disease.

Background: Evaluating the predictors of unfavorable outcomes in patients with ankle fractures is crucial for identifying high-risk patients and implementing personalized treatment strategies. This study aimed to analyze factors that influence quality of life in patients with ankle fractures. Methods: Four databases were consulted. The main outcomes were functionality and quality of life scales combined using the standard mean difference (SMD) (Review Manager 5.4). Results: Eight studies with 2486 patients were included. A significant correlation was found between female sex and worse functionality scores (beta 4.15, 95% CI 1.84-6.46). Additionally, older age was correlated with worse functionality scores (beta -0.24, 95% CI -0.29 to -0.19). Patients with diabetes or metabolic syndrome also had worse outcomes (SMD 0.27, 95% CI 0.18-0.36). High BMI and obesity were also associated with worse quality of life scores (beta 2.62, 95% CI 0.77-4.48). Smokers had greater disability in the analyzed scales (SMD 0.22, 95% CI 0.05-0.39). No significant differences were observed with respect to syndesmotic involvement. Conclusions: Age, sex, diabetes, high BMI, and smoking negatively impact functional outcomes and quality of life in patients with ankle fractures.
RESUMO
PURPOSE/OBJECTIVE: To propose a predictive model for caregivers' psychological distress (including anxiety, depression, and cognitive overload) based on different data gathered from amyotrophic lateral sclerosis (ALS) patients (cognitive level, psychological distress, type of ALS, and sex). RESEARCH METHOD/DESIGN: A cross-sectional study with a sample of 51 ALS patients and their respective main carers. Various instruments were used such as the Beck Anxiety Inventory, ALS Depression Inventory-12, and the Edinburgh Cognitive and Behavioral ALS Screen, Zarit Burden Interview, Self-Rating Depression Scale, and Self-Rating Anxiety Scale for caregivers. RESULTS: ALS type, sex, and cognition were predictive variables for caregiver distress, with the main explanatory variable being the distress of the patients themselves. Spinal ALS led to higher psychological distress in caregivers (ß = .38), as did male patients with ALS and preserved cognition. CONCLUSIONS/IMPLICATIONS: The proposed confirmatory model demonstrates that patients' psychological distress is the best predictor of psychological distress in their caregivers.

RESUMO
Amyotrophic lateral sclerosis (ALS) is a chronic and progressive neurodegenerative disease that leads to the loss of motor neurons. The dietary intake of ALS patients is thought to influence the prognosis and progression of the disease. The aim of this study was to examine the nutritional, clinical and sociodemographic characteristics of ALS patients in Spain. A cross-sectional descriptive study with demographics, clinical anamnesis and anthropometric assessment was carried out. Nutritional intake was recorded and compared with dietary reference intakes (DRI). Forty subjects (25 males; 15 females) aged 54.7 ± 10.17 were included in the study. The mean weight and height were 67.99 ± 8.85 kg and 167.83 ± 8.79 cm, respectively. Clinical phenotype, time to diagnosis, year of onset and family history were not associated with the place of origin. Clinical phenotype had no influence on time of diagnosis. Caloric and protein intakes were adequate, while carbohydrate, vitamin B8 and iodine intakes were significantly lower than the DRI. Lipids; vitamins B1, B2, B3, B5, B6, B12, C and E; sodium; phosphorus; and selenium intakes were significantly higher than the recommended nutritional standards. ALS patients, who are homogeneously distributed throughout our national territory, should modify their dietary habits to minimize ultra-processed products and prioritize foods rich in healthy fats and fiber.

Exposure to stress induced by intermittent repeated social defeat (IRSD) increases vulnerability to the development of cocaine-induced conditioned place preference (CPP) among male mice; however, some defeated mice are resilient to these effects of stress. In the present study we evaluated the effects of vicarious IRSD (VIRSD) in female mice and explored behavioural traits that are potentially predictive of resilience. C57BL/6 female mice (n = 28) were exposed to VIRSD, which consisted of the animals witnessing a short experience of social defeat by a male mouse on postnatal day (PND) 47, 50, 53 and 56. The control group (n = 10) was not exposed to stress. Blood samples were collected on PND 47 and 56 for corticosterone and interleukin-6 determinations. On PND 57-58, female mice performed several behavioural tests (elevated plus maze, hole-board, object recognition, social interaction, TST and splash tests). Three weeks later, the effects of cocaine (1.5 mg/kg) on the CPP paradigm were assessed. VIRSD decreased corticosterone levels (on PND 56), increased interleukin-6 levels, enhanced novelty-seeking, improved recognition memory and induced anxiety- and depression-like symptoms. Control and VIRSD female mice did not acquire CPP, although some stressed individuals with certain behavioural traits - including a high novelty-seeking profile or the development of depression-like behaviour in the splash test shortly after VIRSD - acquired cocaine CPP. Our results confirm that some behavioural traits of female mice are associated with vulnerability or resilience to the long-term effects of social stress on cocaine reward, as previously observed in males.

Multiple Sclerosis (MS) is a neurodegenerative disease characterized by motor and non-motor symptoms, including emotional distress, anxiety, and depression. These emotional symptoms currently have a pharmacological treatment with limited effectiveness; therefore, it is necessary to delve into their relationship with other psychological, functional, or prefrontal alterations. Additionally, exploring non-pharmacological therapeutic alternatives that have shown benefits in addressing emotional distress in MS patients is essential. AIM: To establish a predictive model for the presence of anxiety and depression in MS patients, based on variables such as psychological well-being, functional activity, and prefrontal symptoms. Additionally, this study aimed to propose non-pharmacological therapeutic alternatives based on this model. MATERIALS AND METHODS: A descriptive, observational, and cross-sectional study was conducted with a sample of 64 diagnosed MS patients who underwent functional and cognitive assessments using the following questionnaires and scales: Functional Activities Questionnaire (FAQ), Acceptance and Action Questionnaire (AAQ-II), Experiences Questionnaire (EQ), Self-Compassion Scale Short Form (SCS-SF), Beck Depression Inventory II (BDI-II), State-Trait Anxiety Inventory (STAI), and Prefrontal Symptoms Inventory (PSI). RESULTS: The model showed an excellent fit to the data and indicated that psychological well-being was the most significant predictor of the criteria (ß = -0.83), followed by functional activity (ß = -0.18) and prefrontal symptoms (ß = 0.15). The latter two are negatively related to psychological well-being (ß = -0.16 and ß = -0.75, respectively). CONCLUSIONS: Low psychological well-being is the variable that most significantly predicts the presence of anxiety and depression in MS patients, followed by functional activity and prefrontal alterations. Interventions based on mindfulness and acceptance are recommended, along with nutritional interventions such as antioxidant-enriched ketogenic diets and moderate group physical exercise.
RESUMO
Introduction: Achondroplasia (Ach) is the most frequent cause of dwarfism. The first therapeutic strategy offered to patients with Ach was. However, GH has played un important role in Ach and Hypochondroplasia (Hch), despite short-term and long-term effects. Purpose: The aim of this systematic review and meta-analysis was to assess the efficacy of GH in the height of patients with Ach and Hch in the short and long term. Methods: 12 studies were included selected from the Pubmed database (3 Randomized Clinical trials (RCTs) and 9 prospective studies) from 1993 to 2014. Comparing high and low doses of GH. The systematic review included 9 prospective studies and the high-dose GH arm of the 3 RCTs. Inclusion criteria was focused on paediatric patients with Ach and Hch treated with GH. Demographic variables were collected including age, gender, dose, height and follow-up. The height variables included height increase and height velocity. Finally, 363 patients with Ach and 41 patients with Hcb were included. A was performed with a follow-up from one to 3 years. Results: In patients with Ach the average height velocity at one, two and three years were 2.65, 1.07 and -0.87 cm/years respectively (p<0.05). The RCTs showed a significant increase in height velocity in patients treated with high dose of GH (MD= 1.38, 95% CI: 0.68-2.07, p=0.0001, I2=0%) . Height at one year increased 0.61 cm. The RCTs did not show significant differences (MD 0.11, 95% CI: 0.17-0.39, p=0.44, I2 = 0%). Finally, patients with Hch increased height velocity 4 cm/year at the first year (p<0.05). Conclusion: GH treatment is beneficial in the shor-term height of children with Ach and Hch. GH effect on different ages and subgroups is unknown, as well as its possible long--term consequences
