Published: September 2021

Hazardous knee biomechanics, such as excessive knee affordance link with injuries in volleyball spike jumps (SPJs) and can be reconfigured by the enhancement of internal focus. The study aimed to explore the effects of video tasks illustrating a high-level SPJ on knee movement in the volleyball SPJ with 15 elite male volleyball athletes. This study investigated the knee movements in sagittal, coronal, and transverse planes before and after the video task in SPJ using one-dimensional statistical parametric mapping (SPM 1D) and discrete statistics. The SPM 1D indicated a larger knee flexion angle (31.17–73.19%,t= 2.611, andp= 0.012), increased knee flexion moment (19.72–21.38%,t= 0.029, andp= 0.029), and increased knee adduction angular velocity (49.07–62.64%,t= 3.148, andp= 0.004) after video task; alternatively, smaller knee external rotation angular velocity (45.85–49.96%,t= 5.199, andp= 0.017) and vertical ground reaction (vGRF) (3.13–5.94%,t= 4.096, andp= 0.014; 19.83–21.97%,t= 4.096, andp= 0.024) were found after the task. With discrete value statistics, the video task increased the peak of knee flexion angle while decreased the peak of extension moment, flexion moment, abduction moment, external moment, the first peak vGRF, and related loading rate.Conclusions: The results indicate that knee biomechanics in volleyball SPJ positively influenced by the video task. The task has the athletes control the knee movements more actively and improves the original hazardous movement strategies. Therefore, the video task presumably can abate the occurrence of knee injuries in volleyball SPJ. Further validation especially in the exercise effect is needed in the future.

Objective: The aim was to investigate the relationships among extreme sports participation, sensation seeking, and negative risky behaviors (smoking, drinking alcohol, and gambling) for middle-school students.Methods: Using a convenience sampling procedure, all students from a middle school in a district of Chongqing were selected to participate in the survey, which included questions on their extreme sports participation rate, and smoking, drinking alcohol, and gambling behavior.Results: A sample of 2,987 middle-school students participated in this study. The results showed that the proportions of students participating in extreme sports, smoking, drinking alcohol, and gambling were 19.9, 4.8, 18.4, and 3.0%, respectively. There were significant differences between different genders, schools, place of residence, smoking, drinking, gambling, and sensation seeking of the participation rate of students of extreme sports, the rate of boys, junior middle-school students, urban students, smokers, alcohol drinkers, gamblers, and high-sensation-seeking students were relatively higher than that of girls, senior middle-school students, rural students, no-smokers, no-alcohol drinkers, no-gamblers, and low-sensation-seeking students. Alcohol drinking, gambling, and sensation seeking were associated with extreme sports participation, and the students who drank alcohol, who gambled, and who were high sensation seeking were more likely to participate in extreme sports than those who did not drink alcohol, who did not gamble, and who were low sensation seeking.Conclusion: Middle schools should integrate extreme sports education into physical education and risky-behavior education, strengthen relevant knowledge and safety training, and guide students to meet their sensation-seeking needs through participation in extreme sports instead of risky behaviors.

Published: September 2021

Background: Although numerous motivations for vaping have been identified in adolescents, no study to date has examined a possible link between vaping and attitudes/behaviors that are associated with eating disorders in adolescent females. Examining this question in adolescent females is especially relevant given the higher prevalence of eating disorders in adolescent girls and women compared to adolescent boys and men.Methods: We recruited 299 girls (between 13 to 17 years old) via Facebook advertisement to complete a REDCap survey, which included the Electronic Cigarette Dependence Index (ECDI), Minnesota Eating Behavior Survey (MEBS), and demographic questions. Data were analyzed using nonparametric Spearman rank correlation test in R.Results: Electronic Cigarette Dependence Index (ECDI) scores were correlated with weight preoccupation (WP), binge eating (BE) and compensatory behavior (CB), but not body dissatisfaction (BD). The following were the results of Spearman correlation tests: (1) WP: rho = 0.13, p = 0.02; (2) BD: rho = 0.06, p = 0.28; (3) BE: rho = 0.15, p = 0.0095; (4) CB: rho = 0.021, p = 0.00027.Conclusion: The present study adds to the current literature examining motivations for e-cigarette use in adolescent girls. As eating disorders and e-cigarette dependence are significant public health concerns, our results highlight the need for intervention development.

Objective: This study is to assess the application value of information-based health education and continuity of care in patients with PU (peptic ulcer).Methods: Patients (116) with PU who have been treated in the hospital between January 2019 and October 2020 were taken as research objects and equally assigned to a control group and an observation group in a random manner. In contrast to the routine care applied to the control group, the observation group received information-based health education and continuity of care intervention. The clinical efficacy, the mastery of health knowledge, self-care ability, medication compliance, quality of life, mental state, and nursing satisfaction of the two groups were compared.Results: After the intervention, the total effective rate, health knowledge adequate rate, Exercise of Self-Care Agency (ESCA) scores of all dimensions, the MOS 36-item short-form health survey (SF-36) scores of all dimensions, medication compliance rate, and total nursing satisfaction of the observation group all notably exceeded those of the control group, with a p &lt; 0.05. Patients of the group with continuity of care intervention showed lower Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores, as compared to the group with conventional care (p &lt; 0.05).Conclusion: Information-based health education and continuity of care elevates the medication adherence and nursing satisfaction of patients with PU, enhances disease-related knowledge of patients and their self-care ability, and eventually ameliorates the quality of life and psychological state. It is worthy of clinical application.
Physicians' Knowledge and Practices Regarding Asthma in Jordan: A Cross-Sectional Study
Authors: Dahmash Eman Z. 
Published: September 2021

Objectives: Asthma is a chronic non-communicable disease that causes significant morbidity and mortality and requires ongoing clinical care. Appropriate knowledge by physicians is vital in the management of asthma. Therefore, this study aims to explore and identify the gaps in physicians' knowledge and practices concerning the management of asthma.Methods: A cross-sectional study using an online survey was conducted in Jordan to understand the gap in knowledge and practices in the management of asthma among physicians. A previously validated questionnaire was employed, the Physicians' Practice Assessment Questionnaire (PPAQ). The knowledge questions based on the Global Initiative for Asthma (GINA) guidelines were used to assess knowledge and practice among the study's participants. Predictors of good practice were identified using logistic regression.Results: A total of 271 physicians participated in this survey. The overall knowledge among physicians scored above 78%. However, gaps were pertinent to identifying the signs of asthma attacks that accounted for 61.9% of the participants, whereas only 67.6% of the physicians knew the drugs used for the management of asthma. The study revealed alarming results when practices were assessed, with the overall percentage of physicians applying the required practices did not exceed 57.1 ± 25.7%. Logistic regression analysis to determine predictors of good practice showed that out of several independent variables, physicians who see 6–10 asthma patients per day are five times more likely to follow the guidelines' recommendations in their practice; senior physicians (&gt;50 years old) and those who see 1–5 asthma patients daily are around two times more likely to follow the guidelines (p 0.001).Conclusions: The findings of this study identified the need to transform knowledge into practice. This could be achieved through professional education and constant reminders to physicians in a simple form, as well as a clinical audit of practice. There is a need for novel knowledge transfer approaches to induce behavioral and practice change toward the management of asthma.

Published: September 2021

Background: Intimate partner violence (IPV) affects outcomes of mothers and their offspring. This systematic review collated the worldwide literature on the prevalence rates of different types of IPV in pregnancy.Methods: Two reviewers independently identified cross sectional and cohort studies of IPV prevalence in pregnancy in online databases (PubMed, WOS and Scopus), selected and extracted data [participants' country, study quality, measurement tool (validation and purpose) and rates of IPV in pregnancy]. We considered a high quality study if it had a prospective design, an adequate sampling method, a sample size estimation, a response rate &gt; 90%, a contemporary ascertainment of IPV in the index pregnancy, and a well-developed detailed IPV tool. We performed random effects meta-analysis and explored reasons for heterogeneity of rates.Results: One hundred fifty-five studies were included, of which 44 (28%) met two-thirds of the quality criteria. Worldwide prevalence of physical (126 studies, 220,462 participants), psychological (113 studies, 189,630 participants) and sexual (98 studies, 155,324 participants) IPV in pregnancy was 9.2% (95% CI 7.7–11.1%, I2 95.9%), 18.7% (15.1–22.9%, I2 98.2%), 5.5% (4.0–7.5%, I2 93.4%), respectively. Where several types of IPV were reported combined, the prevalence of any kind of IPV (118 studies, 124,838 participants) was 25.0% (20.3, 30.5%, I2 98.6%). IPV rates varied within and between continents, being the highest in Africa and the lowest in Europe (p &lt; 0.001). Rates also varied according to measurement purpose, being higher for diagnosis than for screening, in physical (p = 0.022) and sexual (p = 0.014) IPV.Conclusions: IPV prevalence in pregnancy varies across countries, with one-quarter of mothers exposed on average globally. Routine systematic antenatal detection should be applied worldwide.Systematic Review Registration: identifier: CRD42020176131.

Published: September 2021

Background: Arthritis with severe varus deformity remains a challenge in total knee arthroplasty (TKA). Until recently, surgeons aimed at a neutral lower limb alignment when performing a TKA. However, the impact of TKA on the ankle joint has been ignored. Therefore, we conducted a systematic review to assess the clinical and radiological changes in the ankle joint after TKA on knees with severe varus deformity.Methods: A systematic search was conducted in four English (PubMed, Embase, Cochrane Library, and Web of Science) and four Chinese (CBM, VIP, CNKI, and Wan Fang Database) databases. Screening of literature and extraction of data were independently performed by two researchers. The modified methodological index for non-randomized studies (MINORS) was used to assess the quality.Results: A total of eight studies were eligible, namely, four prospective and four retrospective studies. TKA resulted in a negative clinical effect in the ankle joint in patients with ankle osteoarthritis. Seven studies reported changes in the mechanical tibiofemoral angle, and four studies reported radiological changes in the hindfoot. The mean score of the MINORS was 9.8 out of eight (9–11).Conclusion: As a result of the correction of the knee osteoarthritis with severe varus deformity following mechanically aligned TKA, the radiological malalignment of the ankle joint was improved. However, some patients experience increased ankle pain after undergoing TKA, especially, if there was a residual knee varus deformity, a stiff hindfoot with varus deformity, or ankle arthritis.

Published: September 2021

Background: Compared with radiotherapy, endoscopic endonasal nasopharyngectomy (EEN) is increasingly used to treat recurrent nasopharyngeal carcinoma (NPC) because of its good prognosis and mild complications. This study aims to investigate the efficacy of EEN in the treatment of recurrent NPC and factors affecting prognosis.Methods: This study included all patients who received EEN for recurrent nasopharyngeal carcinoma from April 2016 to April 2020. All operations were performed in Xiangya Hospital Central South University. The patient's 2-year overall survival (OS) rate, disease-free survival (DFS) rate and significant prognostic factors are reported.Results: There were 38 (67.9%) males and 28 (32.1%) females, with a median age of 43 (range, 24–69 years).43 (76.8%) of the patients in our study were in advanced rT3-rT4 stage and 32 (74.4%) of the patients in the advanced stage had tumor growth closely related to the internal carotid artery (ICA). During a mean follow up period of 44 month (range 1–65 months) post-surgery. The 2-year OS rate was 48.6%, 2-year DFS rate was 42.6%. The 2-year OS rates of rT1-2 and rT3-4 recurrent NPC were 83.9 and 35.6%, respectively. The 2-year DFS rates of rT1-2 and rT3-4 recurrent NPC 76.2 and 56.3%. The advanced T stage were associated with a poor prognosis in terms of OS and DFS.Conclusions: Data indicate that T staging may be an independent prognostic factor for OS and DFS. Through proper preoperative evaluation, EEN is an alternative treatment option for advanced recurrent NPC that ensures a certain level of efficacy and is relatively safe with few complications. However, additional studies with long-term follow-up and a larger sample size are required.

Published: September 2021

Introduction: The benefit of cytoreductive nephrectomy (CN) for metastatic kidney cancer has been challenged recently. The study aimed to evaluate the prognostic roles of surgical resection of primary tumor site for metastatic kidney cancer under a real-world setting.Methods: The Surveillance, Epidemiology, and End Results (SEER) database (2010–2015) and the overall survival (OS) and cancer-specific survival (CSS) were evaluated using the Cox proportional hazards regression model. One-to-one matching using the propensity score was used to estimate and compare the survival rates.Results: The SEER data contain records of 8,932 patients from 2010 to 2015. The data showed that 61.7% of the patients underwent CN while 38.2% did not receive any surgery. The median survival month for a patient without surgery was 4 months and for a patient with surgery was 19 months. The multivariate analysis showed that surgical resection of the primary tumor site was an independent favorable predictor for both OS and CSS (all p &lt; 0.001) in the original and the matching cohort.Conclusions: In the era of target therapy, CN might still be a vital method to treat metastatic kidney cancer.

В обзоре приводятся новые данные о структуре и функции бронхиолярных экзокриноцитов. Впервые нереснитчатые клетки в бронхиолах были описаны ещё А. фон Кёлликером в 1881 г. Детальное изучение этих клеток в бронхиолах человека и кроликов было проведено М. Клара в 1937 г., в честь которого они были названы. В обзоре обсуждаются следующие функции клеток Клара (КК), или бронхиолярных экзокриноцитов: защитная функция, обусловленная секрецией специфических белков, а также жидкого субстрата, располагающегося на поверхности слизистой оболочки; участие в восстановлении повреждённых реснитчатых клеток в качестве своеобразных стволовых (прогениторных) клеток; функция детоксикации вредных веществ, попадающих в лёгкие, а именно: метаболизация ксенобиотиков и канцерогенных веществ; участие в развитии многих форм рака лёгких, источником формирования которых являются бронхиолярные экзокриноциты, включая аденокарциному - наиболее часто диагностируемую опухоль лёгкого.
This review provides new data on the structure and function of bronchiolar exocrine cells. The nonciliary cells in the bronchioles were first described by Kolliker as early as in 1881. The detailed study of these cells in human and rabbit bronchioles was carried out by M. Clara in 1973, and the cells were named after him. The review discusses the following functions of Clara cells or bronchiolar exocrine cells: a protective function due to the secretion of specific proteins, as well as a liquid substrate located on the surface of the mucous membrane; participation in the restoration of damaged ciliary cells as a kind of stem (progenitor) cells; the function of detoxification of harmful substances that enter the lungs, namely: the metabolism of xenobiotics and carcinogens; participation in the development of many forms of lung cancer, the source of the formation of which are bronchiolar exocrine cells, including adenocarcinoma, the most commonly diagnosed lung tumor.

Для выявления характера взаимосвязи спортивного анамнеза лиц, практиковавших в прошлом интенcивные физические нагрузки, и выявленных у них нарушений ритма сердца и внутрисердечной проводимости был проведен ретроспективный анализ медицинских документов 39 мужчинветеранов спорта (средний возраст - 61,6±11,3 года, средняя длительность постспортивного периода - 23,9±17,3 года, средний стаж соревновательной деятельности - 20,1±9,9 года), имеющих установленные сердечно-сосудистые заболевания. Проведено скрининговое обследование на предмет нарушений ритма и проводимости сердца, эхокардиографическое исследование. Выявлено, что распространенность устойчивых пароксизмов фибрилляции предсердий составила 42% в совокупной выборке, увеличиваясь с повышением уровня спортивной квалификации. Желудочковые нарушения ритма высокой градации выявлены у 14% обследованных. Лишь три параметра были достоверно связаны с риском нарушений ритма у ветеранов спорта: уровень спортивной квалификации, наличие генерализованного атеросклероза (антириск-фактор), возраст. Риск нарушений ритма у ветеранов спорта на 43% определяется указанными факторами. Был предложен алгоритм скрининга нарушений ритма у ветеранов спорта на основе клинических данных. Необходимы дальнейшие проспективные наблюдения для валидации алгоритма.
In order to analyze the relationship between the athletic qualiﬁcation and syndrome of cardiac rhythm and conductivity disturbances in former athletes, a retrospective analysis of medical records of 39 male former athletes with cardiovascular complaints (mean age 61,6±11,3 years, mean duration of career in sports 23,9±17,3 years, mean duration of post-athletic period 20,1±9,9 years) was carried out. The patients were screened for cardiac arrhythmias and underwent echocardiography. The overall prevalence of sustained paroxysms of atrial ﬁbrillation was 42%, increasing with the athletic qualiﬁcation. Ryan grade 4 b -5 premature ventricular contractions were found in 14% of patients. 3 parameters were found to be the independent predictors of arrhythmias in former athletes, i. e. athletic qualiﬁcation, multifocal atherosclerosis (as an anti-risk factor), and age. The coefﬁcient of determinance for the created prognostic model reached 43%. Further prospective studies are needed to validate an algorithm.
