Effects of self-efficacy, catastrophizing, fear of movement and joint position sense in the maintenance of wrist unspecific pain in athletes. An observational study.
Wrist pain is a highly prevalent condition in racket sport population. Although
different wrist injuries have been described in the literature as more prevalent in racket sport,
unspecific chronic wrist pain is common problem on amateur population.
Material and methods: A cross-sectional study were conducted between October 2021 to June 2022.
Participants over 18 th suffered for wrist pain were recruited from different sports centers where
racket sports were practiced.
Objective: The aims of this research was to study the relationships and the predictive power of
Self-Efficacy, Catastrophizing, Fear of Movement and proprioception on the persistence of
unspecific wrist pain in athlete population.
Results: One hundred and four athletes participated in the study (54 men and 50 women), most of
them tennis and paddle players. Psychological variables were correlated (P 0.01) with wrist pain
persistence, suggestive of complex interactions between cognitive-affective processes and wrist
unspecific pain in athletes.
Conclusion: The results suggest that targeting high levels of Self-Efficacy, Catastrophizing and Fear
of Movement could be a prognostic factor of wrist unspecific maintained pain in athlete population.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
Damselflies (Coenagrionidae) have been avoiding leaf veins during oviposition for at least 52 million years
Plant-insect interactions can provide extremely valuable information for reconstructing the oviposition behavior. We have studied about 1350 endophytic egg traces of coenagrionid damselflies (Odonata: Zygoptera) from the Eocene, identifying triangular or drop-shaped scars associated with them. This study aims to determine the origin of these scars. Our behavioral study of about 1,800 endophytic eggs from recent coenagrionids indicates that these scars were caused by ovipositor incisions, but without egg insertion. The scar correlates (χ2-test) with leaf veins in both fossil and extant species. We infer that a female would detect the proximity of a leaf vein and avoid egg-laying, generating a scar that also fossilizes. For the first time, a scar produced by the ovipositor has been identified, indicating the existence of undesirable areas for oviposition. Accordingly, we recognize that Coenagrionidae damselflies (narrow-winged damselflies or pond damselflies) have been avoiding leaf veins for at least 52 million years.Fil: Romero Lebrón, María Eugenia.

Pattern of Consumption of Sports Supplements of Spanish Handball Players: Differences According to Gender and Competitive Level
(1) Background: Given the physiological characteristics of handball, players may require the use of certain sports supplements (SS). However, very few studies have investigated the consumption of SS in handball. The aims were to determine the number of handball players who consume SS, to analyze their SS consumption pattern according to gender and competitive level, and to assess whether the SS they consume are supported by scientific evidence, and to which group they belong according to the classification of the Australian Institute of Sport (AIS). (2) Methods: A descriptive-correlational study was carried out on the habitual consumption of SS in 360 federated Spanish players by using a self-administered and validated questionnaire. (3) Results: These showed 65.8% of the sample consumed SS. According to the total number of participants, the most consumed supplements were from Group A: sports drinks (30.8%) and whey protein (30.4%). When analyzing the data by gender, the men’s consumption was significantly higher for whey protein (p < 0.001), caffeine (p = 0.009), and creatine monohydrate (p < 0.001). When analyzed by competitive level, the provincial category players group showed a significantly lower consumption than the rest of the groups for protein bars (p = 0.038), whey protein (p = 0.005) and creatine monohydrate (p < 0.001), while the honor division group showed a significantly higher intake of creatine monohydrate than the remaining groups (p < 0.001). (4) Conclusions: The handball players showed a moderate consumption of SS, without using substances that were not supported by scientific evidence and opting in most cases for supplements belonging to group A from the AIS classification. Men tended to consume more SS, and SS consumption increased based on competitive level
Estudio densidad mineral ósea y factores relacionados en pacientes pediátricos afectos de fibrosis quística
Introducción. La supervivencia de los pacientes con fibrosis quística (FQ) ha mejorado, permitiendo la aparición de complicaciones como la enfermedad ósea. Es fundamental su detección y prevención desde la infancia, ya que puede empeorar la calidad de vida.Objetivos. Estudiar la masa ósea de los pacientes controlados en la Unidad de Fibrosis Quística del Hospital Infantil Miguel Servet. Realizar un análisis descriptivo de variables de la enfermedad y correlacionarlas con la masa ósea.Material y métodos. Estudio observacional, retrospectivo, descriptivo y analítico, en el que se incluyen pacientes pediátricos con densitometría ósea lumbar realizada en 2018-2019.Resultados. Se incluyen 35 pacientes (20 varones) entre 2 y 18 años. Ningún paciente presenta osteoporosis y la media de Z-score de densidad mineral ósea (DMO) a nivel lumbar (L2-L4) para población pediátrica española es de -0,65 ± 1,11.

Gastroprotective Mechanism and Ulcer Resolution Effect of Cyrtocarpa procera
Gastric ulcers are a worldwide health problem and their poor healing is one of the most important causes for their recurrence. We have previously reported the remarkable gastroprotective and anti-Helicobacter pylori activities of the methanolic extract (CpMet) of Cyrtocarpa procera bark. This work investigates, in a murine model, the CpMet gastroprotective mechanism and establishes its preclinical efficacy in the resolution of ethanol-induced gastric ulcers. The results showed that the gastroprotective activity of CpMet is mainly associated with endogenous NO and prostaglandins, followed by sulfhydryl groups and KATP channels. Furthermore, CpMet (300 mg/kg, twice a day) orally administered during 20 consecutive days promoted an ulcer area reduction of 62.65% at the 20th day of the treatment. The effect was confirmed macroscopically by the alleviation of gastric mucosal erosions and microscopically by an increase in mucin content and a reduction in the inflammatory infiltration at the site of the ulcer. No clinical symptoms or signs of toxicity were observed in the treated animals. The results indicate the safety and efficacy of CpMet in promoting high quality of ulcer healing by different mechanisms, but mostly through cytoprotective and anti-inflammatory effects, making it a promising phytodrug for ulcer treatment
Caracterización estructural del sistema ovino-caprino de la región noroeste de República Dominicana (Structural characterization of sheep and goat farming systems in Northwest Dominican Republic)
The aim of this study was to analyze structural aspects of goat and ovine livestock farming systems located in the Norwest of Dominican Republic. The sample (94 farms) was randomly selected with proportional allocation by region. Forty-four variables related to structural and productive aspects were analyzed. The average size of farms was 96 ha and 165 animals. Their facilities are simple, nonspecific and barely functional, with a mean of 2 pens per farm. Farms generally do not have perimeter fences, facilities for breeding, feeding or watering points. The reproductive strategy is the natural breeding throughout the year on most farms, with a ratio of one sire for every 36 females, and there are no breeding records. The first mating takes place with an average weight of 17 kg at 6.5 months of age. Feeding is based on grazing of natural pastures and forests (94%), reaching a stocking density of 0.83 LU/ha. Food supplementation is used in 37% of farms, mainly in sheep and mixed farms. The lambs and goats are sold when they reach 23 kg in weight, around 7 months of age. The farms do not receive technical advice, although 94% of them apply preventive treatments on a regular basis. The mortality rate reached 12%. In general, farms are very heterogeneous in their production structure, management, nutrition and health. Thus, a group of farms developed a traditional system (goats), while the most efficient and technified correspond to sheep and mixed farms
Mixed-method research protocol: Development and evaluation of a nursing intervention in patients discharged from the intensive care unit
Alta de la UCI; Diseño de un método mixto; Intervención de enfermeríaAlta de la UCI; Disseny d'un mètode mixt; Intervenció d'infermeriaICU discharge; Mixed-method design; Nursing interventionAim
(a) To understand patients’ lived experience at intensive care unit (ICU) discharge and (b) to evaluate the impact of a nursing empowerment intervention (NEI) on patients’ anxiety and depression levels at ICU discharge.
Design
A mixed-methods approach will be applied.
Methods
In the qualitative phase, the hermeneutic phenomenological method will be used. Participants will be patients from three university hospitals who will be selected by purposive sampling. Data will be gathered through in-depth interviews and analysed using content analysis. The qualitative data obtained will be employed to develop the nursing intervention. Subsequently, a multicenter, parallel-group, experimental pre-test/post-test design with a control group will be used to measure the effectiveness of the nursing empowerment intervention in the quantitative phase by means of the Hospital Anxiety and Depression Scale (HADS). Simple random probabilistic sampling will include 172 patients in this phase
Distributed deep reinforcement learning resource allocation scheme for industry 4.0 Device-To-Device scenarios
This paper proposes a distributed deep reinforcement learning (DRL) methodology for autonomous mobile robots (AMRs) to manage radio resources in an indoor factory with no network infrastructure. Hence, deep neural networks (DNN) are used to optimize the decision policy of the robots, which will make decisions in a distributed manner without signalling exchange. To speed up the learning phase, a centralized training is adopted in which a single DNN is trained using the experience from all robots. Once completed, the pre-trained DNN is deployed at all robots for distributed selection of resources. The performance of this approach is evaluated and compared to 5G NR sidelink mode 2 via simulations. The results show that the proposed method achieves up to 5% higher probability of successful reception when the density of robots in the scenario is high.This work has been partially funded by Junta de Andalucía (projects EDEL4.0:UMA18-FEDERJA-172 and PENTA:PY18-4647) and Universidad de Málaga (I Plan Propio de Investigación, Transferencia y Divulgación Científica).
