    目的:探索和描述老年人在现实生活中与家庭护理护士的独特护理经历。
    背景:社会中越来越多的老年人导致与年龄相关的损害增加,从而影响他们的生活质量。未来的护理包括“家中的医院”,在那里护理会发生在一个人的私人领域,部分成为临床工作场所。很少的研究集中在老年人如何体验与家庭护理护士的护理遭遇,需要强调。
    方法:多案例研究。
    方法:这些病例依赖于复制逻辑,并采访了五名有目的的老年人。使用定性内容分析对数据进行了分析,并探讨了病例内部和病例之间的差异,并重复了病例之间的发现。
    结果:交叉分析分为三类:“护理常规规则”,“缺乏知识和信息”和“依赖他人的支持”。
    结论:我们的研究发现,老年人在接受家庭护理时面临挑战,包括有限参与他们的护理和需要加强支持。在家庭中实施以人为本的护理会带来道德挑战,需要仔细考虑。家庭护理护士应优先考虑单独了解每个患者,认识到他们超越了他们的病人角色,这需要更彻底和时间敏感的护理接触。
    研究结果是使用COREQ指南报告的。
    对患者进行了访谈,并提供了本研究的数据。
    这项研究强调需要在家庭环境中优先考虑个性化护理,并倾听老年人的声音以提高质量。
    OBJECTIVE: To explore and describe older persons\' unique experiences of care encounters with home care nurses in a real-life context.
    BACKGROUND: The increasing number of older persons in society contributes to increases in age-related impairments compromising their quality of life. Future care consists of \"hospitals at home\" where care encounters occur in a person\'s private domain, partly becoming a clinical workplace. Scant research has focused on how older persons experience care encounters with home care nurses and needs to be highlighted.
    METHODS: Multiple-case study.
    METHODS: The cases relied on replication logic and five purposive sampled older persons were interviewed. Data were analysed using qualitative content analysis and differences within and between cases were explored and findings across the cases were replicated.
    RESULTS: The cross-analysis emerged in three categories: \"Nursing routine rules the care encounters\", \"Lack of knowledge and information\" and \"Dependency on support from others\".
    CONCLUSIONS: Our research has found that older persons face challenges while receiving home care, including limited engagement in their care and the need for enhanced support. Implementing person-centred care in homes poses ethical challenges that require careful consideration. Home care nurses should prioritise understanding each patient individually, recognising them beyond their patient role, which necessitates more thorough and time-sensitive care encounters.
    UNASSIGNED: Findings were reported using COREQ guidelines.
    UNASSIGNED: Patients were interviewed and contributed with data for this study.
    UNASSIGNED: This study emphasises the need to prioritise individualised care in home settings and listen to the voices of older individuals to enhance quality.

    在残奥会举重比赛中,运动执行对称性是受个体运动员特征和运动策略影响的技术要求。识别与个人运动策略相关的元素可以为改善运动表现提供有价值的见解。因此,本案例系列研究旨在探讨肌肉激活对称性及其个体内和个体间变异性,以确定精英残奥会举重运动员中与个体运动策略主要相关的肌肉。
    前三角肌(AD)的双侧肌电图激活,胸大肌(PM),背阔肌(LD),在五名残奥会精英举重运动员中分析了三头肌(TRI)和外斜肌(EO)肌肉,同时进行了四组一次重复的残奥会卧推。获得并转换肌肉激活对称性指数(SI)以考虑独立于个体的评估。变异系数(CV),方差比(VR),计算和平均偏差(MD)以评估肌电图波形和SI的个体间和个体内变异性。
    转化和未转化的SI均表明DA中的整体对称激活,PM,TRI,和LD。在分组数据时,转化的SI显示EO的不对称肌肉激活(平均双侧差异:10%)。运动员在所有分析的肌肉中表现出低的个体内SI变异性(CV<10%),在DA中表现出低的个体间变异性。PM,LD,和TRI(CV<10%;VR:4%-11%;MD:29%-43%)。相比之下,在EO中观察到更高的个体间变异性(CV:23%;VR:23%;MD:72%-81%).
    运动员腹部肌肉激活的最高变异性和不对称性强调了针对这些肌肉的个性化训练方法的重要性,因为它们在个性化运动策略中的作用。
    UNASSIGNED: In Paralympic powerlifting competitions, movement execution symmetry is a technical requirement influenced by individual athlete characteristics and motor strategies. Identifying the elements associated with individual motor strategies can offer valuable insight for improving sport performance. Therefore, this case series study aimed to explore muscle activation symmetry and its intra- and inter-individual variability to determine the muscles mostly related to individual motor strategies in elite Paralympic powerlifters.
    UNASSIGNED: Bilateral electromyographic activation of the anterior deltoid (AD), pectoralis major (PM), latissimus dorsi (LD), triceps (TRI) and external oblique (EO) muscles were analysed in five elite Paralympic powerlifters while performing four sets of one-repetition maximum of Paralympic bench press. Muscle activation symmetry indexes (SI) were obtained and transformed to consider individual-independent evaluation. The coefficient of variation (CV), variance ratio (VR), and mean deviation (MD) were computed to assess inter- and intra-individual variability in electromyographic waveforms and SI.
    UNASSIGNED: Both transformed and non-transformed SI indicated overall symmetric activation in DA, PM, TRI, and LD. Transformed SI revealed asymmetrical muscle activation of EO when grouping data (mean bilateral difference: 10%). Athletes exhibited low intra-individual SI variability in all analysed muscles (CV < 10%) and low inter-individual variability in DA, PM, LD, and TRI (CV < 10%; VR: 4%-11%; MD: 29%-43%). In contrast, higher inter-individual variability was observed in EO (CV: 23%; VR: 23%; MD: 72%-81%).
    UNASSIGNED: The highest variability and asymmetry in abdominal muscle activation among athletes emphasize the importance of personalized training approaches for targeting these muscles due to their role in individualizing motor strategies.

    未经证实:新生儿颞下颌关节(TMJ)结核是一种罕见的实体。未诊断/管理不善的结核病可以传播并危及患者的生命。目的是介绍一例新生儿TMJ结核性骨髓炎,随访11年。
    未经评估:一个半月大的男性新生儿在过去的20天里表现为左耳前方有强烈的肿胀。超声显示无血管,34*25*25mm的低回声病变。下位骨的不规则边缘可能提示侵蚀。抽吸显示脓液。脓液ZN染色显示结核分枝杆菌。排干脓液后,患者接受了抗结核治疗。他在10岁时因不对称而重访。虽然病人的肺结核治好了,研究结果诊断为髁突发育不全伴同侧冠状突增大。下颌骨的分散改善了面部对称性。
    未经证实:尽管脓液显示存在抗酸杆菌,这是不明显的,直到有一个显著的细菌负荷。诊断TMJ的结核性骨髓炎需要进行更高灵敏度的检查。必须使患者意识到TMJ结核性骨髓炎的可能后遗症,并需要适当的治疗。倾斜截骨的角度和牵引改善了下颌骨的水平和垂直分量,从而改善了对称性。据作者所知,以下是新生儿中第一例原发性TMJ结核,并进行了长期随访。
    UNASSIGNED: Tuberculosis of the Temporomandibular joint (TMJ) in a neonate is a rare entity. Undiagnosed/mismanaged tuberculosis can disseminate and be life-threatening to the patient. The purpose is to present a case of tubercular osteomyelitis of TMJ in a neonate with eleven years of follow-up.
    UNASSIGNED: A one-and-a-half-month-old male neonate presented with a firm swelling in front of the left ear for the past 20 days. Ultrasound presented an avascular, hypoechoic lesion of 34*25*25mm. Irregular margins of underlying bone could suggest erosion. Aspiration revealed pus. ZN staining of pus revealed Mycobacterium tuberculosis. After draining the pus, the patient underwent antitubercular therapy. He revisited at ten years of age with a complaint of asymmetry. Although the patient got cured of his tuberculosis, investigations rose to a diagnosis of condylar hypoplasia with ipsilateral coronoid enlargement. A distraction of the mandible improved facial symmetry.
    UNASSIGNED: Although pus revealed the presence of Acid-fast bacilli, it is not evident until there is a significant bacterial load. Escalation of tests with higher sensitivity is needed to diagnose tubercular osteomyelitis of TMJ. Patients must be made aware of possible sequelae of tubercular osteomyelitis of TMJ and need appropriate management. Oblique osteotomy at the angle and distraction improves both horizontal and vertical components of the mandible and thus improves symmetry. To the best of the author\'s knowledge, the following is the first case of primary tuberculosis of TMJ in a neonate and with such an extended follow-up.

    COVID-19大流行的爆发再次使自然灾害的影响成为学术界的热门话题。自然灾害对环境的影响,然而,在现有文献中仍未解决。本研究旨在探讨自然灾害对二氧化碳排放的影响。为此,我们使用1990-2018年期间涵盖138个国家的面板数据集和两种动态面板估计方法。然后,考虑到不同国家二氧化碳排放量的差异,我们运行面板分位数回归来检验自然灾害和二氧化碳排放之间关系的不对称性。我们还讨论了能源消耗在自然灾害和二氧化碳排放之间的中介效应。在进行了一系列稳健性检查后,我们确认我们的结果是稳定和令人信服的。实证结果表明,自然灾害显著减少了CO2排放。然而,自然灾害对CO2排放的影响在CO2排放的不同分位数之间是不对称的。此外,技术水平是自然灾害和二氧化碳排放之间的重要调节因素。中介效应结果表明,自然灾害不仅直接减少了CO2排放,而且通过抑制能源消耗间接促进了碳减排。最后,提供了一些政策含义,以减少二氧化碳排放和自然灾害造成的损害。
    The outbreak of the COVID-19 pandemic has once again made the impacts of natural disasters a hot topic in academia. The environmental impacts of natural disasters, however, remain unsettled in the existing literature. This study aims to investigate the impact of natural disasters on CO2 emissions. For this purpose, we employ a panel dataset covering 138 countries over the period 1990-2018 and two dynamic panel estimation methods. Then, considering the differences in CO2 emissions across various countries, we run a panel quantile regression to examine the asymmetry in the nexus between natural disasters and CO2 emissions. We also discuss the mediating effects of energy consumption between natural disasters and CO2 emissions. After conducting a series of robustness checks, we confirm that our results are stable and convincing. The empirical results indicate that natural disasters significantly reduce CO2 emissions. Nevertheless, the impact of natural disasters on CO2 emissions is asymmetric across different quantiles of CO2 emissions. Furthermore, the technology level serves as an important moderating factor between natural disasters and CO2 emissions. The mediating effect results reveal that natural disasters not only directly reduce CO2 emissions but also indirectly promote carbon reduction by restraining energy consumption. Finally, several policy implications are provided to reduce CO2 emissions and the damage caused by natural disasters.

    背景:对诊断为特发性脊柱侧凸(IS)的儿童出生后第一年的发育运动障碍了解不多。
    目的:本研究旨在比较患有IS的青少年及其健康对应者在出生后第一年不对称或肌张力障碍的发生情况。
    方法:有IS和没有脊柱侧凸的青少年的父母完成了一项关于不对称发生的调查,肌肉张力异常,和孩子第一年的理疗。采用皮尔逊卡方检验和克莱默系数。
    结果:最终分析包括由患有特发性脊柱侧凸(150)和没有脊柱侧凸(377)的青少年父母完成的527项调查。在特发性脊柱侧凸的青少年中,不对称(p=0.001)和肌张力障碍(p=0.001)的频率明显更高。结果还揭示了脊柱侧凸和不对称之间的显着关联(p=0.001),以及肌肉张力(p=0.001)。
    结论:生命第一年的发育不对称或肌张力不当可能被认为是脊柱侧凸发展的潜在因素;然而,这一假设应该在未来的研究中得到证实。诊断为发育障碍的婴儿需要系统观察。
    BACKGROUND: Not much is known about developmental motor disorders in the first year of life of children diagnosed with idiopathic scoliosis (IS).
    OBJECTIVE: This study aimed to compare the occurrence of asymmetry or muscle tone disorders in the first year of life in adolescents with IS and their healthy counterparts.
    METHODS: The parents of adolescents with IS and without scoliosis completed a survey on the occurrence of asymmetry, abnormal muscle tone, and physiotherapy in their children in the first year of life. Pearson\'s chi square test and Cramer\'s coefficient were used.
    RESULTS: The final analysis included 527 surveys completed by parents of adolescents with idiopathic scoliosis (150) and without scoliosis (377). A significantly higher frequency of asymmetry (p= 0.001) and muscle tone disorders (p= 0.001) was noted in adolescents with idiopathic scoliosis. The results also revealed a significant association between scoliosis and asymmetry (p= 0.001), as well as muscle tone (p= 0.001).
    CONCLUSIONS: Developmental asymmetry or improper muscle tone in the first year of life could be considered a potential factor in the development of scoliosis; however, this hypothesis should be confirmed in future studies. Infants diagnosed with developmental disorders require systematic observation.

    背景:乙胺丁醇诱导的视神经病变(EON)最常表现为双侧对称性视力丧失,并且由于缺乏早期发现和有效治疗,常引起严重和不可逆的视力损害。随访1例EON患者罕见的双眼不对称临床表现,观察停药后视功能和视网膜结构的变化,从而进一步了解本病的临床特点。
    方法:一名54岁男性主诉左眼视力逐渐下降。患者的右眼最佳矫正视力为20/20,左眼为20/50。色觉检查显示难以阅读左眼的绿色色板。视野表现为左眼的同心收缩。在停药近一个月后,右眼有类似的视觉功能下降。在最后一次访问中,停药后19个月,双眼视觉功能均显著恢复。在后续光学相干断层扫描(OCT)检查期间,两只眼睛都表现出视网膜神经纤维层的厚度从轻度增厚到变薄,最后是颞部萎缩,神经节细胞内丛状层明显变薄。不同的是,通过黄斑高清OCT在左眼中检测到鼻黄斑外视网膜的可逆性结构紊乱。
    结论:肾病和高血压,损害视网膜微循环,可能会对视网膜的外层造成损害。乙胺丁醇可影响光感受器以及视网膜神经节细胞。
    BACKGROUND: Ethambutol-induced optic neuropathy (EON) most commonly manifests as bilateral symmetrical loss of vision and often cause serious and irreversible visual impairment because of the lack of early detection and effective treatment. We followed a case of EON with rare binocular asymmetric clinical manifestations and observed the changes of visual function and retinal structure after drug withdrawal, so as to further understand the clinical characteristics of this disease.
    METHODS: A 54-year-old man complained of gradual visual decline in the left eye. The patient presented with best-corrected visual acuity of 20/20 in the right eye and 20/50 in the left eye. Color vision examination revealed difficulty in reading green color plates in the left eye. The visual field manifested as concentric contraction in the left eye. After nearly a month of drug withdrawal, the right eye had a similar decline in visual function. At the last visit, 19 mo after drug withdrawal, the visual function significantly recovered in both eyes. During follow-up optical coherence tomography (OCT) examination, both eyes manifested the thickness of the retinal nerve fiber layer from mild thickening to thinning and finally temporal atrophy, and the ganglion cell-inner plexiform layer showed significant thinning. The difference was that a reversible structural disorder in the outer retina of the nasal macula was detected in the left eye by macular high-definition OCT.
    CONCLUSIONS: Nephropathy and high blood pressure, which damage the retinal microcirculation, may cause damage to the outer layer of the retina. Ethambutol may influence photoreceptor as well as retinal ganglion cells.

    自远古以来,II类错牙合病例一直对正畸医生提出挑战。下颌后缩是II类错牙合的最常见特征,而不是上颌前突。二级与不对称的关联,一种叫做不对称下颌后移症(AMR)的疾病,对正畸医生的管理提出了更严峻的挑战。以下案例介绍了使用差分加载技术对AMR的有效管理。一名12岁的小男孩表现为下颌后颌畸形,并伴有面部不对称。他接受了使用固定功能器具的差力加载技术的治疗。
    结果:面部轮廓改善,下颌长度增加。面部不对称性的显著降低也是可观的。
    结论:使用固定功能矫治器的差力加载技术虽然对患者来说最不麻烦,但在这种具有面部不对称的下颌后缩的情况下,可以证明以最小的努力获得优异和令人满意的结果是有益的,也减少了手术矫正的需要。

    Class II malocclusion cases possess a constant challenge to orthodontists since time immemorial. Mandibular retrusion is the most common feature of class II malocclusion, rather than maxillary prognathism. Association of class II with asymmetry, a condition called asymmetric mandibular retrognathia (AMR), gives a tougher challenge to orthodontists for management. The following case presents effective management of AMR using differential loading technique. A young boy aged 12 years presented with mandibular retrognathia associated with facial asymmetry. He was treated with a differential force loading technique using a fixed functional appliance.
    RESULTS: Improved facial profile with increased mandibular length achieved. A significant reduction in facial asymmetry was also appreciable.
    CONCLUSIONS: Differential force loading technique using fixed functional appliance while being least troublesome for the patient may prove beneficial to harness excellent and satisfactory results with minimal efforts in such cases of mandibular retrusion with facial asymmetries and also decrease the need for surgical correction.

    目标:当前的重返运动决定主要基于手术或受伤后经过的时间和力量测量。鉴于数据显示,成功重返竞技体育的比率约为55%,采用能够更好地为回归体育决策提供信息的工具有很强的理由。作者的目标是评估反应强度,作为指导重返运动决定的指标。
    方法:病例对照设计。
    方法:来自国家运动队的15名精英运动员(23[6.0]y)在单侧膝盖受伤后的重返运动方案的最后阶段和16名年龄匹配的对照运动员(22[4.6]y)进行了单侧等距力量测试和24厘米跳投测试。使用成对比较来确定组内腿之间的差异以及组间腿间不对称性的差异。
    结果:强度测量没有区分对照组和康复组;然而,对照组和康复组的接触时间不对称程度有明显差异(Cohend=0.56;-0.14至1.27;8.2%;P=.113),飞行时间(d=1.10;0.44至1.76;16.0%;P=0.002),和反应强度指数(d=1.27;0.50至2.04;22.4%;P=0.002)。
    结论:反应强度数据提供了对持续到重返运动方案最后阶段的功能缺陷的见解。作者的研究结果支持使用动态评估工具来告知重返运动的决定,以限制再伤害的可能性。
    OBJECTIVE: Current return-to-sport decisions are primarily based on elapsed time since surgery or injury and strength measures. Given data that show rates of successful return to competitive sport at around 55%, there is strong rationale for adopting tools that will better inform return to sport decisions. The authors\' objective was to assess reactive strength as a metric for informing return-to-sport decisions.
    METHODS: Case-control design.
    METHODS: Fifteen elite athletes from national sports teams (23 [6.0] y) in the final phase of their return-to-sport protocol following a unilateral knee injury and 16 age-matched control athletes (22 [4.6] y) performed a unilateral isometric strength test and 24-cm drop jump test. Pairwise comparisons were used to determine differences between legs within groups and differences in interleg asymmetry between groups.
    RESULTS: Strength measures did not distinguish the control from the rehabilitation group; however, clear differences in the degree of asymmetry were apparent between the control and rehabilitation groups for contact time (Cohen d = 0.56; -0.14 to 1.27; 8.2%; P = .113), flight time (d = 1.10; 0.44 to 1.76; 16.0%; P = .002), and reactive strength index (d = 1.27; 0.50 to 2.04; 22.4%; P = .002).
    CONCLUSIONS: Reactive strength data provide insight into functional deficits that persist into the final phase of a return-to-sport protocol. The authors\' findings support the use of dynamic assessment tools to inform return-to-sport decisions to limit potential for reinjury.
