Published: May 2023

Introduction:
This study investigates the effects of the COVID-19 pandemic on medical education, research opportunities, and mental health in orthopaedic surgical training programs.

Methods:
A survey was sent to the 177 Electronic Residency Application Service–participating orthopaedic surgery training programs. The survey contained 26 questions covering demographics, examinations, research, academic activities, work settings, mental health, and educational communication. Participants were asked to assess their difficulty in performing activities relative to COVID-19.

Results:
One hundred twenty-two responses were used for data analysis. Difficulties were experienced in collaborating with others (49%), learning through online web platforms (49%), maintaining the attention span of others through online web platforms (75%), and in gaining knowledge as a presenter or participating through online web platforms (56%). Eighty percent reported that managing time to study was the same or easier. There was no reported change in difficulty for performing activities in the clinic, emergency department, or operating room. Most respondents reported greater difficulty in socializing with others (74%), participating in social activities with coresidents (82%), and seeing their family (66%). Coronavirus disease 2019 has had a significant effect on the socialization of orthopaedic surgery trainees.

Discussion:
Clinical exposure and engagement were marginally affected for most respondents, whereas academic and research activities were more greatly affected by the transition from in-person to online web platforms. These conclusions merit investigation of support systems for trainees and evaluating best practices moving forward.

Introduction: Polymethylmethacrylate (PMMA) is a synthetic, inert, biocompatible and nontoxic polymer, the applications in the medical field are numerous, and indications are increasingly broad. Objectives: To evaluate whether the fibrous response to injection of PMMA microspheres into striated muscles confers increased volume and resistance to muscle stretch. Methods: A total of 20 Wistar rats were injected with, 30% PMMA gel into the right rectus abdominis muscle, while the left rectus muscle received SHAM injections. After 4 weeks, all abdominal rectus muscles were measured and stretched on a bench dynamometer until rupture. The samples were analyzed histologically to verify the tissue response to PMMA. Results: The right rectus abdominis muscles of rats that received PMMA gel injection had increased volume and the breaking strength was greater than 100% compared to the left rectus muscles that received SHAM injections. There was a significant deposition of type I and III collagen fibers around the PMMA injection sites. Conclusion: PMMA microspheres implanted into the rectus abdominis muscle of Wistar rats promote neocollagenesis and significantly increase the breaking strength when subjected to stretch test. The mild and desired foreign body type tissue reaction around the PMMA is not objection to the augmentation of the rectus abdominis muscle.

<p><strong>Background. </strong>The <em>Jatropha curcas</em> species can be reproduced asexually by stakes, grafting and meristem cultivation, however, the main way to establish plantations is by means of botanical seed of high physiological quality that will ensure the germination and development of vigorous plants. <strong>Objective</strong>. To evaluate the variations in physiological and biochemical quality in stored seeds of <em>J. curcas</em> caused by accelerated aging deterioration method in different periods of exposure time. <strong>Methodology.</strong> Seeds with 75 days of storage were subjected to aging periods of 96, 72, 48 and 24 h at 40 ± 1 °C and 100 % relative humidity. Treated seeds were measured by germination percentage (PG), electrical conductivity (EC), protein content (CProt), fatty acids (CLip), peroxidation (IP). The lowest germination loss was obtained at 18 days in seeds with 24 h of treatment (93 %), and with 96 h they did not germinate (0 %). The EC identified progressive cell deterioration during the imbibition process (after six hours). The IP rose due to the moisture gain in the seed during the treatment period. The CProt and CLip had minimal variation. <strong>Conclusion.</strong> The physiological and biochemical quality of the <em>Jatropha curcas</em> seed showed serious variations with exposure to different periods of accelerated aging; It can withstand up to 72 hours of aging at 40 ± 1 °C and 100 % relative humidity before losing its viability.</p>
INSECT PESTS PREFERENCE FOR COWPEA: THE DILEMMA OF FARMERS IN WEST AFRICA
Authors: Oso Adeola Abiola , Ashafa Anofi Omotayo 
Published: May 2023

<p><strong>Background: </strong>Cowpea is a cosmopolitan crop cultivated in most of West Africa where the livelihood of people revolves around farming. It is a vital form of livelihood all through the value chain from seed production to farming, grain processing, distribution, and culinary purposes. <strong>Main findings: </strong>The high demographic growth, rapid urbanization, and burgeoning markets of West African countries are the key drivers for the intensification of cowpea production in these regions. Cowpea as a linkage crop connects agriculture to the prevalent local environments of West Africa; farmers to productive resources; and consumers to local healthy foods. As a choice crop among the resource-poor farmers, it is largely grown in intercrop with other food crops such as maize, sorghum, millet, sugar cane, cotton, and cassava. This is due to the ecosystem services and carbon credits derived from its cultivation. These ecosystem services and carbon credits are displayed through its nitrogen-fixing capability, drought-tolerant nature, and ground covering potential against erosion. <strong>Implication: </strong>Although benefits accrue from cultivating this crop, a major constraint to its production is its susceptibility to attack by an array of insect pests. These pests include the pod borer ( <em>Maruca vitrata</em>)<em>, </em>Flower thrips (<em>Megalurothrips </em>sjostedti)<em>, </em>Spiny bugs (<em>Clavigralla spp.</em>)<em>, </em>Other pod sucking bugs (<em>Aspavia armigera, Anoploclemis curvipes, Riptortus dentipe</em>), Whitefly (<em>Bemisia tabaci</em>)<em>, </em>Aphids (<em>Aphis craccivora</em>)<em>, </em>Leafhoppers (<em>Empoasca spp</em>), Foliage beetle(<em>Ootheca mutabilis</em>), Flower beetle (<em>Mylabris spp.</em>)<em> and </em>mites (<em>Tetranychus spp</em>)<em>. </em>Their attack could be so severe that over 90% of harvestable yield may be lost and the farmer is left in a dilemma of fighting hunger and poverty. <strong>Conclusion: </strong>Despite the huge research collaborations in the management of insect pests of cowpea, this paper seeks to find out how much of these documented findings become transferred to resource-poor farmers in West Africa.</p>

Published: May 2023

<p><strong>Background: </strong>At the present, agricultural production systems need to produce more food, in the shortest possible time, and at the same time conserve natural resources. Among the initiatives that have been implemented, agrosilvopastoral systems are a viable strategy with regard to extensive livestock. <strong>Objective:</strong> We characterize the historical trajectory as well as technical and socioeconomic indicators of cattle raising using extensive and agrosilvopastoral practices in the municipality of Pijijiapan, Chiapas, Mexico. <strong>Methodology:</strong> Information was obtained through in-depth interviews with key informants, documentary review, semi-structured interviews, and direct observation in 35 livestock production units (LPU). Qualitative information was organized chronologically and presented in a descriptive, narrative manner. Quantitative data were analyzed using a K-means cluster analysis according to a Livestock Agroecosystem Services Index (ISAGAN according to its Spanish initials) of the LPU. Information was examined using analysis of variance and a non-parametric Kruskal-Wallis test in order to identify differences among clusters. <strong>Results:</strong> Three important stages were identified in the historical trajectory: i) a colonial, pre-livestock raising period with little anthropic intervention, prior to 1900; ii) a period of productive development of livestock raising, from 1900 to 1955, and iii) a period of expansion of extensive livestock raising, beginning in 1955, with significant environmental impacts. More recently, agrosilvopastoral management has been presented as a sustainable alternative to extensive livestock raising. <strong>Implications:</strong> Livestock raising based on grazing is characterized by a tree gradient, a low level of technological development, low use of external inputs, and holistic diversified resource use. <strong>Conclusion:</strong> Of 26 technical and socioeconomic indicators evaluated, technical advisory was the only one which varied (p&lt; 0.05) among clusters; upon increasing the values of this indicator, ISAGAN also increased.</p>
