Authors: Zhang Meng , Zhao Pengfei , Gao Xiaojun , Lai Qinghui 
Published: July 2024

IntroductionThe design of the maize metering device involves centrifugal variable diameter pneumatic and cleaning mechanisms, aiming to enhance the performance and power efficiency of pneumatic maize metering devices. Leveraging the impact of changes in centrifugal diameter and the guidance and positioning of airflow, we optimize the hole insert, seeding plate, seed limit board, and integrated front shell. This optimization facilitates the adjustment of both the quantity and posture of seed filling. As a result, seeds can form a uniform flow within the annular cavity, reducing the wind pressure necessary for regular operation and decreasing power consumption.MethodsA quadratic regression orthogonal rotation combination experiment is conducted using a self-made experiment bench, considering ground speed, wind pressure, and seeding rate as the experiment factors. Furthermore, a comparative experiment involving a novel centrifugal variable-diameter type metering device.ResultsThe results indicate optimal seeding performance when the ground speed is 13.2 km/h, the wind pressure is 1.2 kPa, and the feeding rate is 25 seeds/s. Under these conditions, the quality of feed index reaches 95.20%, the multi-index is 3.87%, and the miss index is 0.93%. Findings reveal that the developed seed metering device achieved a quality of feed index exceeding 93.00% across varying speeds of 12~18 km/h, aligning with the production requirements. Moreover, the actual power consumption of Type B and C is about 85.00% and 98.00% lower than Type A, standing at only 32.90 W at 18 km/h. The COP of Type C is about 86 times and 12 times that of Type A and B, respectively, meeting the demands for efficient production of maize seed metering devices.DiscussionIn comparison to traditional design and structural parameter optimization methods for maize seed metering device, this study is helpful to the sustainable development of maize industry and reduce environmental pollution.

BackgroundMalnutrition is one of the most significant child health problems in developing countries, accounting for an estimated 53% of child deaths per year. Depression is the leading cause of disease-related disability in women and adversely affects the health and well-being of mothers and their children. Studies have shown that maternal depression has an impact on infant growth and nutritional status. However, evidence is scarce regarding the relationship between maternal depression and child malnutrition.ObjectivesThe general objective of this study was to assess the prevalence and associated factors of maternal depression among mothers of undernourished children at comprehensive specialized hospitals in Northwest Ethiopia in 2023.MethodsAn institution-based cross-sectional study was conducted among 465 participants. Outcome variables were assessed using a Patient Health Questionnaire-9 (PHQ-9). Data were analyzed using SPSS-25. Bivariate and multivariable logistic regression analyses were conducted. Variables with a p-value less than 0.05 were considered statistically significant with a corresponding 95% confidence interval (CI).ResultsThe prevalence of maternal depression among mothers of children with undernutrition was 36.4% (95% CI = 32%–41%). According to a multivariate analysis, lack of maternal education (adjusted odds ratio [AOR] = 2.872, 95% CI = 1.502–5.492), unemployment (AOR = 2.581, 95% CI = 1.497–4.451), poor social support (AOR = 2.209, 95% CI = 1.314–3.713), perceived stigma (AOR = 2.243, 95% CI = 1.414–3.560), and stunting (AOR = 1.913, 95% CI = 1.129–3.241) were factors significantly associated with maternal depression.ConclusionThe overall prevalence of maternal depression was higher among mothers of children with undernutrition. This higher prevalence was associated with several factors, including lack of education, unemployment, poor social support, high perceived stigma, and stunted physical growth in the children themselves. To decrease maternal depression, we can address these factors by increasing the level of maternal education and employment opportunities, strengthening social support systems, reducing stigma, and providing interventions to reduce stunting.

ContextFrench Guiana is a French overseas department where very different linguistic, cultural and societal populations live together in a small area. Health issues and their specific epidemiological profiles call for research projects crossing several cultures. In this context, health mediators have a role to play in research. The aim of this study was to describe the perceptions, attitudes and opinions on research of mediators and researchers collaborating on research projects, and to describe the strengths and difficulties encountered during this cooperation.MethodsThe Inter-med project was conducted in French Guiana between February 2022 and April 2023 on the base of semi-directive interviews with mediators, or researchers, all working in health research in the intercultural context of French Guiana. The socio-demographic characteristics of the participants were described. An inductive thematic analysis was carried out on all the interviews, and word occurrence analysis on certain themes. The information was triangulated with field coordination notebooks from two epidemiological surveys conducted in French Guiana between 2021 and 2022.ResultsA total of 26 semi-structured interviews were conducted and 1,328 notebook pages analyzed. Mediation was described as an indispensable interface between the world of research and that of the population targeted by a survey. Mediators have a role to play at different stages of projects, in respect of good clinical practice, ethics and legislation. They act as interfaces between languages, concepts and representations. Their profession remains under-defined and under-dimensioned. The jobs offered are often precarious. Mediation work is emotionally costly, calls on soft skills and requires a combination of rigor and flexibility. All these aspects are implemented in the specific world of research, where there are common concepts and divergent perceptions. Researchers and mediators converge on a common goal: improving health.ConclusionThis study covers several aspects of the development and implementation of research projects. Respect for good clinical practice and people, transparency and data quality are redundant concerns, and this study touches on ethnocentrism, stigmatization and cultural representations. This study points out that the integration and recognition of mediators could be beneficial in research conducted in a cross-cultural context.

ObjectiveTo compare the therapeutic efficacy of robot-assisted and manual screw placement techniques for the treatment of pelvic fractures.MethodsThis study included patients with pelvic fractures admitted to our orthopedic department between January 2020 and January 2022. They were randomly assigned to either the robot-assisted group or the control group. Various parameters, including surgical duration, intraoperative bleeding, fluoroscopy frequency, postoperative pain, length of hospitalization, postoperative hematological indices, postoperative functional scores, and postoperative complications, were compared between the two groups.ResultsThere were no significant differences in age, sex, body mass index, and preoperative hematological parameters between the two groups. The robot-assisted group exhibited significantly shorter surgical duration, lower fluoroscopy frequencies, lower postoperative pain scores, and shorter length of hospitalization compared to the control group. At 3 and 6 months postoperatively, patients in the robot-assisted group demonstrated significantly higher Majeed functional scores in comparison to the control group. However, there were no significant differences in Majeed scores at 12 months postoperatively. Moreover, there were no significant differences in postoperative complications between the two groups.ConclusionRobot-assisted minimally invasive treatment of pelvic fractures using hollow screws effectively reduced surgical duration, mitigated intraoperative bleeding and postoperative pain, shortened hospital stays, and promoted faster functional recovery.

ObjectiveTo evaluate the effect of comfort nursing on postoperative nausea and vomiting in patients with idiopathic scoliosis undergoing posterior correction surgery.Methods92 patients with idiopathic scoliosis were taken as the subjects and segmented into a control group and an experimental group (n = 46/each group). The former received routine care, while the latter one performed comfortable care. The observation period is 48 h after surgery. Record and compare the incidence, grade, frequency, and pain level of nausea and vomiting in both groups, as well as postoperative physical signs and symptoms, drug use, and postoperative recovery. Investigating the patient's satisfaction with nursing care. The research data is analyzed using SPSS26.0 software. P &lt; 0.05 means statistical significance.ResultsWithin 48 h after surgery, the number of nausea and vomiting in the control is 24 and the experimental group is 8, with an incidence rate of 52% and 16%. The latter is significantly lower than that in the control. The average number of nausea and vomiting episodes in the control is 2.5, significantly higher than the 0.45 episodes in the experimental set. There is a significant difference in the frequency of nausea and vomiting/temperature and urine volume/scores of nausea, vomiting, dizziness, headache, decreased appetite, and discomfort between the two groups (P &lt; 0.05).ConclusionComfortable care has a relieving effect on postoperative nausea and vomiting in patients with idiopathic scoliosis after posterior correction surgery. It can low down the incidence and frequency of nausea and vomiting, and reduce the score of related symptoms. Comfortable care can also help patients recover after surgery, increase dietary intake, and improve nutritional status. Comfortable care has a significant effect on postoperative nausea and vomiting in cases with idiopathic scoliosis undergoing posterior correction surgery, which can improve their postoperative recovery and quality of life.

ObjectivesSocial media has become integrated into adolescents’ lives and influences body image perceptions. Our study examined four patterns of social media use (SMU): non-active, active, intensive, and problematic. We hypothesised that intensive SMU and problematic SMU would be associated with negative body image (negative subjective body weight) and over/underestimated body weight congruence, compared to non-active and active SMU. In addition, we expect these associations to be stronger for girls.MethodsData from 190,892 respondents aged 11, 13, and 15 from 42 countries involved in the Health Behaviour in School-aged Children study were analysed.ResultsFindings revealed higher rates of intensive or problematic SMU among adolescents who perceived themselves as too fat or too thin. Two-level regression analyses showed intensive and problematic SMU as more likely to perceive themselves as too fat or too thin than active users. The association was significant among intensive and problematic girl social media users, whereas, among boys, the relationship was only significant for problematic users.ConclusionOur findings highlight the importance of assessing SMU patterns to evaluate associations with body image.

Published: July 2024

ObjectivesElectronic health records (German: elektronische Patientenakte - ePA) are an important healthcare tool. However, in Germany, current participation remains low for their national ePA. To rectify this, the German government recently adopted an opt-out approach to their national ePA system. The objective of this study is to investigate and provide a brief overview of German public attitudes towards this approach to inform policymakers with evidence-based insights.MethodsFour public focus groups were conducted with 12 German citizens to discuss their opinions on the German governments new opt-out approach to the ePA.ResultsThree major thematic categories were identified (Contributors to Opt-Out Implementation, Barriers to Opt-Out Implementation, and Contingent Factors) to describe citizen views on the opt-out approach for the ePA.ConclusionThe public is generally supportive of an opt-out approach to ePAs in Germany, as they see the benefits ePAs can provide to German society; but they are skeptical on how successful this approach might be due to extant issues that policymakers must be aware of in order to successfully implement an opt-out approach for Germany’s national ePA system.
Maṇḍala or Sign? Re-Examining the Significance of the “Viśvavajra” in the Caisson Ceilings of Dunhuang Mogao Caves
Authors: Shen Li 
Published: July 2024

This article delves into the exploration of a significant sign, the “viśvavajra”, found in the caisson ceilings of Buddhist esoteric art in Dunhuang’s Mogao Caves. These caissons, featuring the viśvavajra sign in the center, were prevalent from the mid-Tang period to the Western Xia dynasty (ninth to thirteenth centuries) and are recorded by The Overall Record of Dunhuang Mogao Grottoes under description as “Jiaochu Jingxin”. Similar caissons are also found in Western Buddhist Caves near Dunhuang, and Yulin Caves in Guazhou County, indicating a distinct regional character. Focusing on a well-preserved and intricately detailed example from Cave 361, this article aims to elucidate the specific tantric significance of the viśvavajra at the center of the caissons within the broader context of Buddhist art. Drawing from related tantras, the discussion explores how the sign and its surrounding compositions align with a particular homa (fire offering) maṇḍala, specifically the śāntika maṇḍala crucial to numerous Tantric Buddhist rituals. Furthermore, the article examines the evolution of caisson of this type of maṇḍala over time. By comparing the mid-Tang example from Cave 361 with the late Tang period’s Cave 14, a noticeable shift in format becomes apparent. The viśvavajra sign takes on new significance, embodying “the samaya of all Tathāgatas”. Ultimately, the article explores how the significance of the viśvavajra sign transforms into an allusion to Vairocana or Rocana under the Sino-Tibetan Esoteric Buddhist context in the Hexi Corridor during the early Northern Song and Western Xia dynasty.

O sexismo impacta a sociedade como um todo, causando repercussões não apenas nas mulheres, mas também nos homens. Dessa forma, percebe-se a falta de atenção integral à saúde do homem, que é frequentemente negligenciada, estigmas sociais criam barreiras que dificultam a busca por serviços e cuidados de saúde. Assim, o presente estudo objetivou apresentar os obstáculos para o reconhecimento da fragilidade mental e os fatores que contribuem para o adoecimento psicológico dos homens. O estudo em questão trata-se de uma revisão integrativa da literatura, onde a coleta de dados foi realizada entre janeiro e fevereiro de 2024, nas seguintes bases de dados: Scientific Eletronic Library Online (SciELO), Latino-Americana e do Caribe em Ciências da Saúde (LILACS), National Library of Medicine (PubMed), Medical Literature Analysis and Retrievel System Online (MEDLINE). Teve como critérios de inclusão: publicados entre 2014-2024; gratuitos; texto completo; publicados em português que tivessem correlação com a temática, com o operador booleano: AND. A falta de acesso e relutância em buscar serviços de saúde mental são agravadas pela ideia de que cuidar da própria saúde é sinal de fraqueza. Isto é especialmente evidente entre homens que são parte de minorias sociais, que enfrentam as pressões tradicionais associadas ao desgaste físico e psicológico desde a infância. Com isto, os resultados ressaltam a necessidade imediata de adotar estratégias de intervenção que considerem as especificidades e desafios enfrentados pelos homens em relação à saúde mental, ressaltando a importância de ações educativas constantes por parte dos profissionais de saúde de atenção primária.

Published: July 2024

O tétano é uma doença infecciosa causada pela toxina secretada pelo Clostridium tetani, chamada tetanospasmina. O tétano neonatal, também chamado de tétano umbilical ou "doença dos 7 dias", pode afetar os recém-nascidos durante os primeiros 28 dias de vida. O objetivo do presente estudo é coletar dados a respeito da notificação de Tétano Neonatal na última década no estado do Espírito Santo, correlacionando com a importância da prevenção, diagnóstico e tratamento. Este estudo é de caráter descritivo, em que os dados avaliados são referentes a usuários do sistema de saúde no estado do Espírito Santo - Brasil, entre os anos de 2012 e 2022, sendo o ano de 2022 o último com dados disponíveis até o presente momento. O Espírito Santo apresenta um número de casos de tétano neonatal extremamente baixos, tendo em vista que nos últimos 10 anos registrou-se apenas 5 casos, número esse considerado diminuído para a situação, o que nos demonstra uma possível causa de subnotificação. O tétano neonatal é uma patologia subnotificada, fato esse que prejudica as análises e estudos acerca da sua distribuição e morbidade para o país, corroborando com o que é encontrado em maior parte da literatura científica.

Published: July 2024

As intervenções cirúrgicas na odontologia oferecem riscos aos pacientes que fazem uso de anticoagulantes e antiagregantes plaquetários. No que se refere ao atendimento odontológico, o exame clínico deve sempre preceder e guiar a solicitação dos exames complementares. Embora nem sempre sejam necessários para definição do diagnóstico, muitas vezes auxiliam a planejar a conduta terapêutica mais apropriada. No caso dos pacientes que vão ser submetidos a procedimentos odontológicos mais invasivos e que fazem uso de anticoagulantes orais e/ou antiagregantes plaquetários, a solicitação de exames laboratoriais se faz primordial. Este trabalho se constitui em uma revisão de literatura acerca da importância da solicitação e interpretação de exames laboratoriais por parte do Cirurgião-Dentista aos pacientes que fazem uso de anticoagulantes orais e/ou antiagregantes plaquetários. A metodologia desenvolvida se estabeleceu a partir de uma revisão narrativa, qualitativa, de cunho descritiva, na qual foram utilizadas as bases de dados SciELO - Scientific Eletronic Library Online, a PubMed- National Library of Medicine e a Plataforma LILACS por meio de palavras chaves. Ficou evidenciado neste trabalho que o conhecimento desse assunto é de fundamental importância, uma vez que as condutas adequadas entregam maior segurança para o paciente, que em certos casos podem seguir com o tratamento farmacológico que faz uso, sem a necessidade de suspensão do medicamento, mas que nos casos mais complexos precisam, junto com o médico que o acompanha indicar suspensão temporária ou mesmo substituição da medicação pelo período de tempo seguro.
