    猫泛白细胞减少症是由猫泛白细胞减少症病毒(FPV)引起的一种传染性病毒性疾病。一种密切相关的病原体是犬细小病毒(CPV),和该病毒中的氨基酸取代使其能够获得猫科动物的宿主范围。在猫科动物宿主中,由CPV引起的疾病表现出与FPV或较温和的症状相似的症状,导致其诊断不足。这项研究的目的是确定具有泛白细胞减少症临床症状的猫中CPV2型(CPV-2)的存在,并评估将商业CPV抗原测试用于FPV的临床诊断。
    来自斯洛伐克中部的59只猫的样品被包括在研究中。收集直肠拭子并使用商业抗原测试对细小病毒感染进行临床测试。通过靶向病毒VP2基因的PCR确认抗原阳性样品。用Sanger法建立PCR产物的序列。
    在59个样本中,通过抗原和PCR测试发现23例细小病毒感染呈阳性(38.9%)。国家生物技术信息中心BLASTn应用的分析显示与FPV成对同一性99.78-100%。本研究中纳入的细小病毒感染猫的死亡率为8.69%(2/23)。
    尽管未证实患有CPV-2的猫科动物疾病,CPV抗原检测能够检测FPV感染.
    UNASSIGNED: Feline panleukopenia is a contagious viral disease caused by the feline panleukopenia virus (FPV). A closely related pathogen is canine parvovirus (CPV), and amino acid substitutions in this virus allow it to acquire a feline host range. In feline hosts, the disease induced by CPV manifests with similar symptoms to those caused by FPV or milder ones, leading to its underdiagnosis. The aim of this study was to determine the presence of CPV type 2 (CPV-2) in cats with clinical symptoms of panleukopenia and to assess the use of commercial CPV antigen tests for the clinical diagnosis of FPV.
    UNASSIGNED: Samples from 59 cats from central Slovakia were included in the study. Rectal swabs were collected and clinically tested for parvovirus infection using a commercial antigen test. Antigen-positive samples were confirmed by PCR targeting the viral VP2 gene. The sequences of the PCR products were established with the Sanger method.
    UNASSIGNED: Of 59 samples, 23 were revealed to be positive for parvovirus infection by both antigen and PCR test (38.9%). Analysis with the National Center for Biotechnology Information BLASTn application showed 99.78-100% pairwise identity with FPV. The mortality rate of parvovirus-infected cats included in this study was 8.69% (2/23).
    UNASSIGNED: Although feline disease with CPV-2 was not confirmed, the CPV antigen test was able to detect FPV infection.

    Opisthorchisviverrini感染是东南亚农村地区的一个紧迫的健康问题,并且与胆管癌的风险有关。尽管控制努力,高感染率持续存在,包括治疗后再感染的证据。这项研究旨在通过在3年的时间内在泰国农村流行地区采取综合的“单一健康”方法来解决这一公共卫生问题。该研究包括来自Udon他尼省的3600名参与者的数据,泰国,在2020年至2022年期间,涉及综合流行病学数据收集和危险因素分析,以了解各种干预措施对社区疾病传播的影响。通过监测2021年和2022年O.Viverrini再感染的发生率来评估干预措施的有效性。2020年,确认了218例O.viverrini感染(6.0%)。重要的风险因素包括靠近水体和食用生鱼。影响参与者感染风险的变量(P<0.001)是教育水平,参与传统仪式,卫生条件差,附近的水体中没有鸭子,寄生虫的自我药物治疗,和家庭中的多种感染。狗,猫,鲤鱼的患病率为5.4%,6.3%,11.5%,分别。地理分析显示,水体周围有成群的受感染家庭。干预措施,包括深度访谈,焦点小组讨论,健康教育,驱虫治疗,和使用当地自由放养鸭子的生物防治,实施了,第二年没有人再感染,第三年的患病率最低为0.3%。这项研究为感染流行率的动态变化提供了有价值的见解,为有效的疾病控制和社区健康促进做出重大贡献。这种综合的“一个健康”方法被证明是预防和控制opisthorchiasis的有效策略。
    Opisthorchis viverrini infection is a pressing health issue in rural Southeast Asia and is associated with the risk of cholangiocarcinoma. Despite control efforts, high infection rates persist, including evidence of reinfection post-treatment. This study aimed to address this public health concern through an integrated One-Health approach in endemic areas in rural Thailand over a 3-year period. The study included data from 3600 participants from Udon Thani Province, Thailand, during the years 2020 to 2022 and involved integrated epidemiological data collection and risk factor analysis to understand the impact of various interventions on disease transmission in the community. The efficacy of interventions was assessed by monitoring the incidence of O. viverrini reinfection in 2021 and 2022. In 2020, 218 cases of O. viverrini infection (6.0%) were identified. Significant risk factors included proximity to water bodies and consumption of raw fish. Variables contributing to infection risk among participants (P < 0.001) were education level, engagement in traditional ceremonies, poor sanitation, absence of ducks in nearby water bodies, self-medication for parasitic conditions, and multiple infections within a household. Dogs, cats, and cyprinoid fish showed prevalence rates of 5.4%, 6.3%, and 11.5%, respectively. Geographic analysis revealed clusters of infected households around water bodies. Interventions, including in-depth interviews, focus-group discussions, health education, anthelminthic treatment, and biological control using local free-range ducks, were implemented, resulting in no human reinfections in the second year and a minimal 0.3% prevalence rate in the third year. This study offers valuable insights into the dynamic changes in infection prevalence, making a significant contribution to effective disease control and community health promotion. This integrated One-Health approach proved to be an effective strategy for the prevention and control of opisthorchiasis.

    冠状病毒经常感染人类和动物,表现出重组和跨越不同物种的能力。猫可以被认为是研究冠状病毒感染的模型,其中猫冠状病毒(FCoV)是与胃肠道疾病相关的主要肠道病原体。在这种动物中,病毒可以获得巨噬细胞的嗜性,导致一种致命的疾病称为猫传染性腹膜炎(FIP)。在这项研究中,通过CD14阳性选择从26只FIP猫和32只FCoV阳性健康猫的静脉全血中分离出单核细胞衍生的巨噬细胞。对吞噬作用和呼吸爆发活动进行了调查和比较。这是第一项比较受FIP影响的猫和FCoV感染阳性的健康猫的巨噬细胞活性的研究。我们的结果表明,在FIP的猫中,吞噬和呼吸爆发活动显著降低。我们的结果支持宿主免疫在猫的冠状病毒病机理中的可能作用,支持未来针对这种全身性疾病的免疫防御研究。
    Coronavirus frequently infects humans and animals, showing the ability to recombine and cross over to different species. Cats can be considered a model for studying coronavirus infection, in which feline coronavirus (FCoV) represents a major enteric pathogen related to gastroenteric disease. In this animal, the virus can acquire tropism for macrophage cells, leading to a deadly disease called feline infectious peritonitis (FIP). In this study, monocyte-derived macrophages were isolated by CD14-positive selection in venous whole blood from 26 cats with FIP and 32 FCoV-positive healthy cats. Phagocytosis and respiratory burst activities were investigated and compared between the groups. This is the first study comparing macrophage activity in cats affected by FIP and healthy cats positive for FCoV infection. Our results showed that in cats with FIP, the phagocytic and respiratory burst activities were significantly lower. Our results support the possible role of host immunity in Coronaviridae pathogenesis in cats, supporting future research on the immune defense against this systemic disease.

    大鼠肺虫病或神经管圆线虫病是一种影响人类和动物的脑寄生虫感染。其临床体征和症状可以从轻度的自我解决到严重的危及生命的状况。研究表明,在感染的早期阶段进行治疗干预比在后期阶段更有效。然而,感染的早期诊断通常是有问题的,如果不知道暴露和/或检测到脑脊液中寄生虫的DNA或针对寄生虫的抗体。这需要腰椎穿刺,这是一种侵入性手术,通常需要住院治疗。这项研究评估了一种负担得起且侵入性较小的替代方法,可以通过PCR从潜在感染动物的外周血中检测寄生虫DNA。在2019年2月至2022年8月期间,当地将58只动物(55只狗和3只猫)的血液样本提交给我们的实验室,有执照的兽医。从全血提取DNA,等离子体,血清,和/或使用QiagenDNeasy血液和组织试剂盒根据制造商的方案填充细胞。使用AcanITS1测定法通过实时PCR测试所有58只动物,并且还使用AcanR3990测定法测试这些动物中的32只(31只狗;1只猫)。两种方法的PCR结果分为强阳性>阳性>弱阳性>阴性,模棱两可的结果,基于信号的强度。使用AcanITS1和AcanR3990测定检测到的感染百分比为12.72%(7/55)和20.68%(6/29),分别。检测到的总感染率为34.37%(11/32),只有两只动物在两种检测中都呈阳性。参与这项研究的三只猫通过两种测定测试均为阴性。这些结果是有希望的,需要进一步研究以提高灵敏度,包括可能影响血液检测的变量,如寄生虫负荷,和实验室方法。
    Rat lungworm disease or neuroangiostrongyliasis is a cerebral parasitic infection that affects humans and animals alike. Its clinical signs and symptoms can range from mild self-resolving to serious life-threatening conditions. Studies suggest therapeutic interventions during the early stages of infection to be more effective than in later stages. However, early diagnosis of infection is usually problematic without the knowledge of exposure and/or detection of the parasite\'s DNA or antibody against the parasite in the cerebrospinal fluid. This requires a lumbar puncture, which is an invasive procedure that generally requires hospitalization. This study evaluates an affordable and less invasive alternative to detect parasitic DNA by PCR from the peripheral blood of potentially infected animals. Blood samples from 58 animals (55 dogs and 3 cats) with clinical suspicion of infection were submitted to our lab between February 2019 and August 2022 by local, licensed veterinarians. DNA was extracted from whole blood, plasma, serum, and/or packed cells using the Qiagen DNeasy Blood & Tissue Kit as per the manufacturer\'s protocol. All 58 animals were tested by real-time PCR using the AcanITS1 assay and 32 of these animals (31dogs; 1 cat) were also tested using the AcanR3990 assay. The PCR results for both assays were classified into strongly positive > positive > weakly positive > negative, and equivocal for ambiguous results, based on the strength of the signal. The percent infection detected using the AcanITS1 and AcanR3990 assays was 12.72% (7/55) and 20.68% (6/29), respectively. The overall percent infection detected was 34.37% (11/32), with only two animals testing positive by both assays. The three cats involved in this study tested negative by both assays. These results are promising and warrant further investigations to increase sensitivity including variables that might affect detection in the blood, such as parasite load, and laboratory methodologies.

    为了评估高流量氧疗(HFOT)的安全性和可行性,并记录在支气管镜检查±支气管肺泡灌洗(BAL)期间接受HFOT或常规氧疗(COT)的狗和猫的SpO2和去饱和事件。
    在2023年1月至5月期间接受支气管镜±BAL的狗和猫被纳入研究。患者随机分为两组:HFOT(HFOT组;两只猫和四只狗)和COT(COT组;一只猫和五只狗)。HFOT和COT在支气管镜检查开始时开始。HFOT以1L/kg/min的气体流速在100%的FiO2和34°C(儿科模式)或37°C(成人模式)的温度下递送。COT以1.5L/min的速率通过支气管镜的工作通道递送。评估了HFOT的安全性和可行性,在整个过程中,每30s通过脉搏血氧饱和度(SpO2)测量一次。
    HFOT在狗和猫中均可行且安全,未报告并发症。虽然两组之间的去饱和发作次数(SpO2<94%)没有显着差异,HFOT组没有患者出现严重的去饱和(SpO2<90%)。相比之下,COT组2例患者的SpO2<90%.在T0时,HFOT组的平均SpO2明显高于COT组(98%±2%vs.94±2%),T0.5(98%±2%vs.94%±3%)和T1(98%±2%vs.94%±4%)。
    对于作者的知识,这是迄今为止在狗和猫的支气管镜检查中使用HFOT进行的最大规模的研究。我们的结果表明,HFOT在支气管镜±BAL检查中是可行且安全的。此外,HFOT可以降低接受支气管镜和BAL的狗和猫的去饱和发作的风险。
    UNASSIGNED: To evaluate the safety and feasibility of high flow oxygen therapy (HFOT), and to record SpO2 and desaturation episodes in dogs and cats receiving HFOT or conventional oxygen therapy (COT) during bronchoscopy ± bronchoalveolar lavage (BAL).
    UNASSIGNED: Dogs and cats undergoing bronchoscopy ± BAL between January and May 2023 were included in the study. Patients were randomly allocated to two groups: HFOT (HFOT group; two cats and four dogs) and COT (COT group; one cat and five dogs). HFOT and COT were started at the beginning of the bronchoscopy. HFOT was delivered with a gas flow rate of 1 L/kg/min at an FiO2 of 100% and a temperature of 34°C (pediatric mode) or 37°C (adult mode). COT was delivered through the working channel of the bronchoscope at a rate of 1.5 L/min. The safety and feasibility of HFOT were assessed, and peripheral oxygen saturation (SpO2) was measured by pulse oximetry every 30 s throughout the procedure.
    UNASSIGNED: HFOT was feasible and safe in both dogs and cats with no complications reported. While there was no significant difference in the number of desaturation episodes (SpO2 < 94%) between the two groups, none of the patients in the HFOT group experienced severe desaturation (SpO2 < 90%). In contrast, two patients in the COT group had an SpO2 < 90%. Mean SpO2 was significantly higher in the HFOT group compared to the COT group at T0 (98% ± 2% vs. 94 ± 2%), T0.5 (98% ± 2% vs. 94% ± 3%) and T1 (98% ± 2% vs. 94% ± 4%).
    UNASSIGNED: To the authors\' knowledge, this is the largest study conducted to date using HFOT during bronchoscopy in dogs and cats. Our results suggest that HFOT is feasible and safe during bronchoscopy ± BAL. Furthermore, HFOT may reduce the risk of desaturation episodes in dogs and cats undergoing bronchoscopy and BAL.

    背景:牙周病是猫中最常见的诊断问题。众所周知,牙周疾病不仅会引起各种口腔健康问题,而且还会导致全身性疾病。氧化应激可能是全身性疾病和牙周炎之间的联系。我们的研究旨在说明牙周炎对猫氧化应激发展的影响。此外,研究了牙龈细菌菌群的变化。
    方法:基于临床和实验室检查,将50只猫分为正常(n=25)和中度至晚期牙周炎(n=25)两组。血清总抗氧化能力(TAC),总氧化剂状态(TOS),测定还原型(GSH)和氧化型谷胱甘肽(GSSG)。此外,从所有猫的龈下菌斑中取样进行细菌培养。
    结果:血清TOS,GSSG,GSSG与GSH比率,和氧化应激指数(OSI),计算为TOS与TAC的比率在有牙周病的猫明显更高,与对照组相比,TAC显著降低(p<0.05)。细菌培养结果表明,患者分离的菌落数量高于对照组。此外,对这些数据的分析显示,牙周指数与氧化应激呈正相关。
    结论:我们的结果表明,猫的牙周炎与主要的氧化应激有关。此外,氧化剂因素,如TOS和OSI,与抗氧化因子相比,可能更好地表明牙周炎患者存在氧化应激状况。
    BACKGROUND: Periodontal diseases are the most frequently diagnosed problem in cats. It has been well-established that periodontal diseases could not only cause various oral health issues but could also contribute to systemic diseases. Oxidative stress is a possible link between systemic diseases and periodontitis. Our study aimed to illustrate the influence of periodontitis on oxidative stress development in cats. Furthermore, the changes in the bacterial flora of the gums were investigated.
    METHODS: Based on the clinical and laboratory examinations, fifty cats were divided into two groups normal (n = 25) and moderate to advanced periodontitis (n = 25). Serum total antioxidant capacity (TAC), total oxidant status (TOS), reduced (GSH) and oxidized glutathione (GSSG) were measured. In addition, samples were taken from the subgingival plaques of all cats for bacterial culture.
    RESULTS: Serum TOS, GSSG, GSSG to GSH ratio, and oxidative stress index (OSI), calculated as the ratio of TOS to TAC in cats with periodontal disease were significantly higher, and TAC was significantly lower (p < 0.05) compared with controls. The results of bacterial culture indicated that the number of isolated bacterial colonies is higher in patients than in the control group. Additionally, the analysis of these data showed a positive association between periodontal index and oxidative stress.
    CONCLUSIONS: Our results revealed that periodontitis in cats is related to a main oxidative stress. Furthermore, oxidant factors such as TOS and OSI, compared to antioxidant factors, may better indicate the presence of oxidative stress conditions in patients with periodontitis.

    在中远端猫科动物肱骨上发现的(看似)骨周围弓的髁上孔仍然存在争议。一些学者主张该孔与在人类Struthers韧带存在下形成的上突软骨孔之间具有同源性。其他理论包括它作为支持带的存在,将正中神经和肱动脉保持在弯曲肘部的解剖位置。不幸的是,这些理论缺乏调查的严谨性。非侵入性成像模式的出现,比如微型计算机断层扫描,使研究人员能够在不拆卸的情况下检查骨骼的内部解剖结构。因此,对三个猫科动物(Feliscatus)肱骨标本进行了显微计算机断层扫描研究,同时检查了髁上孔的内部解剖结构。不像肱骨,猫科动物髁上孔细的外周弓未能引起任何骨小梁或钙化灶。在其起源处粘附于肱骨骨膜的同时,非骨拱,典型的肌肉肌腱,插入与肱骨上髁内侧相关的骨鞍中,提示(前庭)臂肌的肌腱或肌腱延伸,喙臂长肌是最有可能的候选者。
    The supracondylar foramen with a (seemingly) osseous peripheral arch noticed on the medio-distal feline humeri had remained disputed among anatomists. Some scholars have argued in favor of homology between this foramen and the supracondyloid foramen formed in presence of the ligament of Struthers in humans. Other theories include its presence as a retinaculum holding the median nerve and brachial artery to their anatomical position in a flexed elbow. Unfortunately, these theories lack investigative rigor. The emergence of non-invasive imaging modalities, such as micro-computed tomography, has enabled researchers to inspect the internal anatomy of bones without dismantling them. Thus, a micro-computed tomographic investigation was conducted on three feline (Felis catus) humeri specimens while the internal anatomy of the supracondylar foramina was examined. Unlike the humerus, the thin peripheral arch of the feline supracondylar foramen failed to elicit any osseous trabeculae or foci of calcification. While adhering to the humeral periosteum at its origin, the non-osseous arch, typical of a muscular tendon, attaches into the bony saddle related to the medial humeral epicondyle suggestive of a tendon or aponeurotic extension of a (vestigial) brachial muscle, with the coracobrachialis longus emerging to be the most likely candidate.

    皮肤癣菌病是一种传染性真菌感染,主要影响猫。由于其人畜共患潜力以及对动物和公共卫生的影响,它在兽医学中提出了重大挑战。快速可靠的诊断对于防止疾病传播至关重要,指导治疗决策,和监测疾病控制工作。尽管有一些关于猫皮肤癣菌病诊断方法的研究,来自同一样本的它们之间的比较缺乏数据。缺乏普遍接受的黄金标准诊断方法,突显了对诊断猫科动物皮肤癣菌病的多方面方法的需求。
    本研究旨在全面评估不同诊断技术的准确性和有效性。
    为此,通过皮肤镜检查分析了48只猫的样本,直接头发检查,使用各种培养基进行真菌培养(Mycosel,Sabouraud,和皮肤癣菌测试培养基),和聚合酶链反应(PCR)。
    直接检查和皮肤镜检查结果不令人满意。Mycosel和Sabouraud是次优的。DTM表现出优越的选择性,使其成为传统方法中最可靠的。PCR是表现最好的,表现出奇异的灵敏度,特异性,和准确性。
    该研究表明,PCR可能是临床实践中诊断猫皮肤癣菌病的首选方法,特别是当快速和准确的结果是必不可少的。
    UNASSIGNED: Dermatophytosis is a contagious fungal infection that affects mainly cats. It poses significant challenges in veterinary medicine due to its zoonotic potential and impact on animal and public health. Rapid and reliable diagnosis is crucial for preventing the spread of the disease, guiding treatment decisions, and monitoring disease control efforts. Although there are several studies on diagnostic methods in feline dermatophytosis, the comparison between them from the same sample lacks data. The absence of a universally accepted gold standard diagnostic method highlights the need for a multifaceted approach to diagnosing feline dermatophytosis.
    UNASSIGNED: This study aims to assess the accuracy and efficacy of different diagnostic techniques comprehensively.
    UNASSIGNED: For this, 48 samples of cats were analyzed by dermoscopy, direct hair examination, fungal culture using various media (Mycosel, Sabouraud, and Dermatophyte Test Medium), and polymerase chain reaction (PCR).
    UNASSIGNED: Direct examination and dermoscopy yielded unsatisfactory results. Mycosel and Sabouraud were suboptimal. DTM demonstrated superior selectivity, making it the most reliable among traditional methods. PCR was the top performer, exhibiting singular sensitivity, specificity, and accuracy.
    UNASSIGNED: The study suggests that PCR may be the preferred choice for diagnosing feline dermatophytosis in clinical practice, especially when rapid and accurate results are essential.

    BACKGROUND: Hemotropic mycoplasmas, hemoplasmas, are epi-erythrocytic parasitic bacteria that can be transmitted through blood transfusion.
    OBJECTIVE: To study the prevalence of hemoplasma infection of potential feline blood donors and investigate the association between Hemoplasma spp. quantitative polymerase chain reaction (qPCR) positivity in blood units and selected variables.
    METHODS: Seven thousand five hundred seventy-three blood units from 4121 privately-owned potential donor cats.
    METHODS: Retrospective observational cross-sectional study. The Banco Sangue Animal (BSA)-Animal Blood Bank medical database was reviewed for all feline donations performed in 2022 in Portugal, Spain, and Belgium. Baseline characteristics and results of blood-borne pathogens screening tests were extracted from the medical records.
    RESULTS: Two hundred twelve of 4034 Portuguese donor cats and 2 of 70 Spanish donor cats tested positive for Hemoplasma spp. qPCR in 2022 leading to an overall estimated prevalence of 5.2% (95% CI: 4.5%-5.9%) in potential blood donors. Using multivariable generalized estimation equation models, Hemoplasma spp. qPCR was more often positive among blood units issued from male cats (OR = 1.9, 95% CI: 1.4-2.6, P < .0001), units positive for FeLV (OR = 2.8, 95% CI: 1.4-5.6, P = .0023), and units collected in winter months (OR = 2.5, 95% CI: 1.7-3.6, P < .0001).
    CONCLUSIONS: This study underscores the importance of Hemoplasma spp. and other relevant blood-borne pathogens screening at every donation. Implementing stringent screening protocols is crucial to mitigate the risk of hemoplasma transmission via blood transfusions, thereby safeguarding the health and welfare of cats receiving transfusions.

    背景:眼睛的黄斑变性是失明的常见原因,影响全球8%的人口。在患有中央视网膜双侧病变的成年猫中,我们探索了运动感知训练可以限制视觉系统相关退化的可能性。我们评估了视觉训练如何影响行为表现和白质结构。最近,我们提出(Kozak等人。在TranslVisSciTechnol10:9,2021)中,一种针对低视力患者的新的运动敏锐度测试,通过同时感知形状和运动,实现全视野功能评估。这里,我们将此测试整合为为期10周的运动感知训练的最后一步。
    结果:将猫分为三组:仅视网膜病变的猫和两组经过训练的猫,视网膜损伤训练和控制训练。行为数据显示,患有视网膜病变的训练有素的猫在运动任务中表现优异,即使困难只依赖于敏锐度。在5个不同的时间点发生病变之前和之后进行7次T-MRI扫描,其次是基于Fixel和分数各向异性分析。在视网膜病变的猫中,训练导致dLGN中基于Fixel的分析指标的局部化和百分比下降减少,与未经训练的猫相比,尾状核和海马体。在运动敏感区域V5/PMLS,在视网膜损伤的未经训练的猫和受过训练的猫中,纤维密度的显着降低同样强烈,在两组中达到40%。具有不受中央视网膜损失影响的分数各向异性值的唯一皮质区域是区域V5/PMLS。在其他可视化ROI中,在未经训练的视网膜病变组中,分数各向异性值随着时间的推移而增加,而在视网膜病变受训组中,它们下降,并保持在与受训对照组相似的水平。
    结论:总体而言,我们的MRI结果显示,在中央视网膜缺失诱导后不久,运动训练对白质结构有稳定作用.我们建议为低视力患者引入早期运动敏锐度训练,瞄准完整活跃的视网膜周边,可能有助于大脑可塑性过程朝着更好的视力方向发展。
    BACKGROUND: Macular degeneration of the eye is a common cause of blindness and affects 8% of the worldwide human population. In adult cats with bilateral lesions of the central retina, we explored the possibility that motion perception training can limit the associated degradation of the visual system. We evaluated how visual training affects behavioral performance and white matter structure. Recently, we proposed (Kozak et al. in Transl Vis Sci Technol 10:9, 2021) a new motion-acuity test for low vision patients, enabling full visual field functional assessment through simultaneous perception of shape and motion. Here, we integrated this test as the last step of a 10-week motion-perception training.
    RESULTS: Cats were divided into three groups: retinal-lesioned only and two trained groups, retinal-lesioned trained and control trained. The behavioral data revealed that trained cats with retinal lesions were superior in motion tasks, even when the difficulty relied only on acuity. 7 T-MRI scanning was done before and after lesioning at 5 different timepoints, followed by Fixel-Based and Fractional Anisotropy Analysis. In cats with retinal lesions, training resulted in a more localized and reduced percentage decrease in Fixel-Based Analysis metrics in the dLGN, caudate nucleus and hippocampus compared to untrained cats. In motion-sensitive area V5/PMLS, the significant decreases in fiber density were equally strong in retinal-lesioned untrained and trained cats, up to 40% in both groups. The only cortical area with Fractional Anisotropy values not affected by central retinal loss was area V5/PMLS. In other visual ROIs, the Fractional Anisotropy values increased over time in the untrained retinal lesioned group, whereas they decreased in the retinal lesioned trained group and remained at a similar level as in trained controls.
    CONCLUSIONS: Overall, our MRI results showed a stabilizing effect of motion training applied soon after central retinal loss induction on white matter structure. We propose that introducing early motion-acuity training for low vision patients, aimed at the intact and active retinal peripheries, may facilitate brain plasticity processes toward better vision.
