Kearns-Sayre Syndrome (KSS) is a variant of mitochondrial disorder caused by a Mitochondrial Deoxyribonucleic Acid (mtDNA) deletion. Clinical manifestations of KSS can include different organ and system involvement. Different organ malfunctions, more often cardiac dysfunction, can lead to death. No effective treatment of this condition exists to date. Here, we report two patients with KSS. Female patient with a large-scale deletion of 7,020 base pairs (bp) suffered from hypogonadism, diabetes mellitus with fluctuating glucose levels, and had poor general health. A male patient with a common 4,977 bp deletion did not have diabetes mellitus but had impaired glucose tolerance. He also had a higher level of general health than our female patient. Both patients had reduced Bone Mineral Density (BMD). In female patients, calcium and vitamin D supplementation combined with metabolic therapy and nutritional drink supplements helped increase BMD (up to 32% in L1-L4). Comparing these two patients suggests that the larger the mtDNA deletion is, the more severe the course of the disease is. Not only does the size of the mtDNA deletion probably determine the severity of the disease, but also such factors as mtDNA heteroplasmy level, presence of mtDNA duplications, and pleioplasmy. Moreover, continuous nonconsecutive metabolic therapy and nutritional supplements are helpful in the prevention of deterioration of symptoms and general health.

卡恩斯-赛尔综合征(KSS)是线粒体脱氧核糖核酸(mtDNA)缺失引起的线粒体疾病的一种变异型。KSS 的临床表现可包括不同器官和系统的受累。不同器官的功能障碍(更常见的是心脏功能障碍)可导致死亡。迄今为止,尚无有效的治疗方法。在此,我们报告了两名 KSS 患者。女性患者的碱基对大范围缺失达 7,020 个,患有性腺功能减退症、糖尿病和血糖波动,全身健康状况较差。一名患有常见的 4 977 碱基对缺失的男性患者没有糖尿病,但糖耐量受损。他的一般健康水平也高于我们的女患者。这两名患者的骨密度(BMD)都有所降低。在女性患者中,钙和维生素 D 的补充与代谢疗法和营养饮料的补充相结合,有助于增加 BMD(L1-L4 达 32%)。对这两名患者进行比较表明,mtDNA缺失越大,病程就越严重。决定疾病严重程度的可能不仅是 mtDNA 缺失的大小,还有 mtDNA 异源水平、mtDNA 是否存在重复和多倍体等因素。此外,持续的非连续性代谢疗法和营养补充剂也有助于预防症状和总体健康状况的恶化。

Among the numerous changes that occur in skeletal muscle during aging, the reduced regeneration potential after an injury is largely due to the impaired ability of satellite cells to proliferate and differentiate. Herein, using the freeze-fracture electron microscopy technique, we analyzed both the incidence and size of dihydropyridine receptors (DHPRs) tetrads (4 particles) in cultured myotubes from a young subject (28 years) after 9 days of differentiation and from an old subject (71 years) after 9 and 12 days of differentiation. Compared to young myotubes, at 9 days of differentiation old myotubes exhibited: i) a lower incidence and a smaller size of DHPR clusters and ii) a lower number of complete tetrads. At 12 days of differentiation values of incidence, size and number of complete tetrads in old myotubes were instead comparable with those of young myotubes at 9 days of differentiation. Collectively, these results indicate that in aged myotubes the synthesis process of the proteins involved in the excitation-contraction coupling mechanism, such as the DHPR, is somehow slowed, supporting previous studies evidence of a decrease in the differentiation potential of myotubes from elderly individuals.

在骨骼肌衰老过程中发生的众多变化中,受伤后再生潜力降低的主要原因是卫星细胞增殖和分化能力受损。在此,我们利用冷冻断裂电子显微镜技术,分析了年轻受试者(28 岁)的肌管在分化 9 天后和老年受试者(71 岁)的肌管在分化 9 天和 12 天后的二氢吡啶受体(DHPRs)四联体(4 个颗粒)的发生率和大小。与年轻肌管相比,在分化 9 天时,老年肌管表现出:i) 较低的 DHPR 群发生率和较小的 DHPR 群大小;ii) 较低的完整四聚体数量。在分化 12 天时,老肌管的发生率、大小和完整四聚体数量与分化 9 天时的年轻肌管相当。总之,这些结果表明,在老年肌管中,参与兴奋-收缩耦合机制的蛋白质(如DHPR)的合成过程在某种程度上减慢了,这也支持了之前关于老年肌管分化潜力下降的研究证据。

This study aims to evaluate the efficacy of selective laser trabeculoplasty in improving the intraocular pressure in patients diagnosed with open-angle glaucoma. A comprehensive search was performed across electronic databases, including PubMed, Scopus, and Web of Science, until June 2024, using keywords related to "selective laser trabeculoplasty" and "open-angle glaucoma." Studies were chosen based on set eligibility criteria. Data extraction was carried out by two independent reviewers, and statistical analyses were performed using a random-effects model to calculate the pooled mean differences in IOP reduction and overall success rates. The initial search yielded 3111 articles, with 23 studies included in the systematic review and 22 in the meta-analysis. The pooled MD in IOP reduction between the SLT and control groups was -1.44 mm Hg (95% CI: -2.19 to -0.70, p < 0.01). Subgroup analyses revealed a MD of -0.76 mm Hg (95% CI: -1.31 to -0.21, p < 0.01) when comparing SLT to medication, and -0.42 mm Hg (95% CI: -0.64 to -0.19, p < 0.01) when comparing 180-degree SLT to 360-degree SLT. The pooled success rate favored SLT with an odds ratio (OR) of 0.71 (95% CI: 0.51 to 0.99, p = 0.05). There was significant heterogeneity among the studies (I² = 71%). SLT is effective in lowering IOP in OAG patients, demonstrating significant efficacy compared to medication and different SLT protocols. The findings underscore SLT's potential as a reliable treatment option. However, the observed heterogeneity underscores the necessity for standardized protocols in future research to improve comparability and verify SLT's long-term effectiveness.

本研究旨在评估选择性激光小梁成形术对改善开角型青光眼患者眼压的疗效。在 2024 年 6 月之前,我们使用与 "选择性激光小梁成形术 "和 "开角型青光眼 "相关的关键词在 PubMed、Scopus 和 Web of Science 等电子数据库中进行了全面检索。根据设定的资格标准选择研究。数据提取由两名独立审稿人完成,并使用随机效应模型进行统计分析,计算出眼压降低率和总体成功率的汇总平均差异。初步检索共获得 3111 篇文章,其中 23 项研究被纳入系统综述,22 项研究被纳入荟萃分析。SLT组和对照组之间眼压降低的总平均值为-1.44 mm Hg(95% CI:-2.19 至-0.70,p < 0.01)。亚组分析显示,SLT 与药物治疗相比,MD 为-0.76 毫米汞柱(95% CI:-1.31 至 -0.21,p < 0.01);180 度 SLT 与 360 度 SLT 相比,MD 为-0.42 毫米汞柱(95% CI:-0.64 至 -0.19,p < 0.01)。SLT的成功率为0.71(95% CI:0.51-0.99,P = 0.05)。各研究之间存在明显的异质性(I² = 71%)。SLT能有效降低OAG患者的眼压,与药物治疗和不同的SLT方案相比,疗效显著。研究结果凸显了 SLT 作为一种可靠治疗方案的潜力。然而,观察到的异质性强调了未来研究中标准化方案的必要性,以提高可比性并验证 SLT 的长期有效性。

Acute muscle pain is muscle soreness that occurs during or within 24 hours of strenuous activity. Possible causes of acute muscle pain include localized muscle trauma, muscle tear, contusion with acute hemorrhage, or acute compartment syndrome. Isolated ruptures of the rectus femoris muscle are rare clinical conditions that result from excessive muscle strain following an abrupt contraction, incorrect movement, or sudden snap that exceeds the physiological limit of strain that the muscle can withstand. To date, there are few published reports evaluating the results of non-invasive treatment of such injuries. Herein, we report an unusual case of isolated distal rectus femoris tear in a 46-year-old female patient with no risk factors, who initially presented with extensor muscle weakness and pain and was treated conservatively with functional rest, physiotherapy, and cryotherapy.

急性肌肉疼痛是指在剧烈运动期间或 24 小时内出现的肌肉酸痛。急性肌肉疼痛的可能原因包括局部肌肉创伤、肌肉撕裂、急性出血挫伤或急性隔室综合征。股直肌孤立性断裂是一种罕见的临床病症,是由于肌肉突然收缩、不正确的运动或突然扣动后过度拉伸,超过了肌肉所能承受的生理极限。迄今为止,很少有公开报道对此类损伤的非侵入性治疗效果进行评估。在此,我们报告了一例不寻常的孤立性股直肌远端撕裂病例,患者是一名 46 岁的女性,无任何危险因素,最初表现为伸肌无力和疼痛,接受了功能性休息、理疗和冷冻疗法等保守治疗。

Hand-grip strength was evaluated in 757 recreational downhill skiers and compared to 1021 community-dwellers. Findings are reported for age and sex categories consistent with community-dwelling norms. Effect size (Cohen's d) was calculated to estimate the clinical relevance of strength differences between populations. Most male and half of the female age categories of downhill skiers demonstrated higher grip strength of the dominant hand (moderate to large effect size) compared to the reference population. Hand-grip strength in skiers declined with age at a similar rate as in the reference population. Relative grip strength (per kg body mass) was significantly and positively correlated with physical activity (hours/week), and with the number of ski days per year, and negatively with body mass. Thus, hand-grip strength may be related to the type, volume and intensity of exercise regularly performed. These results can help to assess whether the individual hand-grip strength is above or below average with regard to the normal population and the skier population as well and will support advice for training and/or rehabilitation.

对 757 名休闲下坡滑雪者的手握力进行了评估,并与 1021 名社区居民进行了比较。报告了与社区居民标准一致的年龄和性别分类结果。通过计算效应大小(Cohen's d)来估计不同人群之间力量差异的临床相关性。与参照人群相比,大多数男性和半数女性年龄组的速降滑雪者的主导手握力较强(中等至较大的效应大小)。随着年龄的增长,滑雪者手部握力的下降速度与参照人群相似。相对握力(每公斤体重)与体力活动(每周小时数)和每年滑雪天数呈显著正相关,而与体重呈负相关。因此,手握力可能与经常进行的运动类型、运动量和运动强度有关。这些结果有助于评估个人的手握力是否高于或低于正常人群和滑雪人群的平均水平,并为训练和/或康复提供建议。

Explosive strength is fundamental in the performance of athletes. The objective is to identify the criteria used for the prescription of Explosive Strength Training (EST) and to verify the changes it produces in futsal players. A systematic review of studies analyzing the criteria used for the prescription of explosive strength training was conducted in PubMed/MEDLINE and Scielo, considering the period between 2017 and 2023. The search strategy used the terms: players, Futsal, Futsal training, strength, physical exercise, explosive strength, intervention, experimental study. Data extraction included: year of publication, country, sample, protocol performed (content and activity developed, duration, intensity, frequency, total weeks). A total of six studies were identified. Fifty percent of the studies were developed in Brazil, the others in Italy, Spain and Portugal. Five studies applied a training of 2 sessions per week and one indicated 2-3 sessions. Three studies describe the training sessions (study 1: 15-30 minutes, study 2: 20-25 minutes, study 3: 1 hour). Five studies used 1RM and one study used subjective perception of exertion (PSE). The contents of the interventions were varied, from squats with weights, accelerations and decelerations, leg press, leg extension, plyometrics. The training criteria for explosive strength were: intensity controlled by a 1RM, frequency of 2 to 3 sessions per week, duration of 15 to 30 minutes per session and the training contents were varied. These results suggest positive changes in CMJ, increasing explosive strength from ∼2.0 to 4.6 cm (5.8 to 13.7%). These findings highlight the need to develop a more standardized protocol to optimize the benefits of explosive strength training in this athletic population.

爆发力对运动员的表现至关重要。本研究旨在确定爆发力训练(EST)的处方标准,并验证其对五人制足球运动员产生的变化。我们在 PubMed/MEDLINE 和 Scielo 上对用于分析爆发力训练处方标准的研究进行了系统性综述,时间跨度为 2017 年至 2023 年。检索策略使用的术语包括:球员、五人制足球、五人制足球训练、力量、体育锻炼、爆发力、干预、实验研究。数据提取包括:发表年份、国家、样本、执行的方案(内容和开展的活动、持续时间、强度、频率、总周数)。共确定了六项研究。50%的研究在巴西开展,其他研究在意大利、西班牙和葡萄牙开展。五项研究采用了每周两次的训练,一项研究采用了 2-3 次的训练。三项研究描述了训练时间(研究 1:15-30 分钟;研究 2:20-25 分钟;研究 3:1 小时)。五项研究使用了 1RM 值,一项研究使用了主观用力感(PSE)。干预内容多种多样,包括负重深蹲、加速和减速、压腿、伸腿、负重等。爆发力训练的标准是:强度由 1RM 控制,频率为每周 2 至 3 次,每次持续时间为 15 至 30 分钟,训练内容多种多样。这些结果表明,CMJ 发生了积极变化,爆发力从 2.0 厘米增至 4.6 厘米(5.8% 至 13.7%)。这些研究结果突出表明,有必要制定一个更加标准化的方案,以优化爆发力训练对这一运动人群的益处。

These findings highlight the need to develop a more standardized protocol to optimize the benefits of explosive strength training in this athletic population.</p>","PeriodicalId":46459,"journal":{"name":"European Journal of Translational Myology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142477414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate changes in protein signaling associated with muscle regeneration in aged rats with obesity and diabetes following high-intensity interval training (HIIT) and SP supplementation. Forty male Wistar rats weighting 280-325 g were used in this study. Obesity was induced by eight weeks of a high-fat diet, and diabetes was induced by intraperitoneal injection of 40 mg/kg streptozocin. Rats were randomly divided into control (CON), sham, SP, HIIT, and HIIT+SP groups. HIIT was performed five times per week during the 8-week period. SP dose was 50 mg/kg. Real-time PCR was used to evaluate the expression of myogenin, MyoD1, and Pax7. The decreases in body mass in the HIIT, HIIT+SP and SP groups were significantly higher than those in the sham and CON groups (p=0.0001). The soleus muscle mass increased significantly only in the HIIT and HIIT+SP groups (p<0.01). HIIT+SP improved fasting blood glucose and insulin levels more than HIIT alone and SP (p<0.05), while HIIT increased the expression levels of myogenic factors more than other groups (p=0.0001). In conclusion HIIT alone had a significant impact on myogenic factors, whereas Spirulina had an effect only when combined with HIIT.

本研究旨在探讨肥胖和糖尿病老年大鼠在接受高强度间歇训练(HIIT)和补充 SP 后,与肌肉再生相关的蛋白质信号的变化。本研究使用了 40 只体重 280-325 克的雄性 Wistar 大鼠。肥胖是通过八周的高脂饮食诱发的,糖尿病是通过腹腔注射 40 毫克/千克链脲佐菌素诱发的。大鼠被随机分为对照组(CON)、假组、SP组、HIIT组和HIIT+SP组。在为期 8 周的时间里,每周进行五次 HIIT。SP 剂量为 50 毫克/千克。采用实时 PCR 评估肌原蛋白、MyoD1 和 Pax7 的表达。HIIT组、HIIT+SP组和SP组的体重下降幅度明显高于假组和CON组(P=0.0001)。比目鱼肌质量仅在 HIIT 组和 HIIT+SP 组有明显增加(P=0.0001)。

Introduction: Adipocyte levels including leptin and FABS-4 levels, adiponectin, obesity, and vitamin D can be related to the occurrence and exacerbation of MS disease.

Objective: This research aimed at determining the relationship between VDR gene changes and clinical and inflammatory factors in patients with relapsing-remitting multiple sclerosis (RRMS).

Method: This case/control study was conducted based on the ethical principles of Helsinki. RRMS disease was confirmed based on history, clinical signs, radiological signs, and neurologist's diagnosis. The research population consisted of healthy people and patients with RRMS referring to Hazrat Rasool Akram Hospital between 2021 and 2023 who met the criteria for entering the research.

Results: FokI polymorphism is associated with a substantial increase in risk, with an odds ratio of 7.28, for those with the FF genotype who have RRMS compared to healthy individuals (OR=7.28: 95% CI; 1.86, 28.41). The presence of FokI polymorphism significantly raises the likelihood of developing RRMS in persons with the FF genotype compared to healthy individuals, with an odds ratio of 28.7. RRMS patients with genotypes did not exhibit a significant increase in risk compared to controls for FokI, ApaI, TaqI, and BsmI polymorphisms.

Conclusion: None of the studied polymorphisms revealed a significant risk in obese patients with different genotypes compared to the obese people. Further research, including more cases, is needed to avoid results that could be inflated by small samples or low frequencies of minor alleles.

导言:脂肪细胞水平(包括瘦素和FABS-4水平)、脂肪连通素、肥胖和维生素D可能与多发性硬化症的发生和加重有关:本研究旨在确定复发缓解型多发性硬化症(RRMS)患者 VDR 基因变化与临床和炎症因素之间的关系:这项病例/对照研究是根据赫尔辛基伦理原则进行的。根据病史、临床体征、放射学体征和神经科医生的诊断确认 RRMS 疾病。研究对象包括2021年至2023年期间在Hazrat Rasool Akram医院就诊的符合研究标准的健康人和RRMS患者:与健康人相比,FokI 多态性与 RRMS 风险大幅增加有关,FF 基因型 RRMS 患者的几率比为 7.28(OR=7.28:95% CI;1.86,28.41)。与健康人相比,FF基因型患者出现FokI多态性会显著增加患RRMS的可能性,几率比为28.7。与对照组相比,具有FokI、ApaI、TaqI和BsmI多态性基因型的RRMS患者的风险没有明显增加:结论:与肥胖人群相比,所研究的多态性在不同基因型的肥胖患者中均未显示出明显的风险。为了避免因样本少或小等位基因频率低而导致结果夸大,还需要进一步的研究,包括更多的病例。

Longitudinal analysis of lower limb muscle activity and ankle tendon biosignals using structural equation modeling. 利用结构方程模型对下肢肌肉活动和踝关节肌腱生物信号进行纵向分析。

We collected biosignals from 63 participants and extracted the features corresponding to each level of exerted muscle force. Data were classified into typical and atypical patterns. Data analysis was performed using the Linear Latent Curve Model (LCM) and the Conditional Linear LCM. The typical patterns demonstrated a high degree of fit. Factors, such as ankle circumference and muscle mass, influenced the model intercept. A larger ankle circumference indicated attenuation of signal transmission from the tendon to the skin surface, leading to lower biosignal values.  These results indicate that biosignals from the tendons near the ankle can be captured using piezoelectric film sensors. There are studies that define biosignals originating from tendons as mechanotendography. It has been demonstrated that the relationship between biosignals originating from tendons and the exerted muscle force can be explained linearly. Insights from this study may facilitate individualized approaches in the fields of motion control and rehabilitation. Physiological studies to elucidate the mechanisms underlying biosignal generation are necessary.

我们收集了 63 名参与者的生物信号,并提取了与每个用力水平相对应的特征。数据被分为典型模式和非典型模式。我们使用线性潜曲线模型(LCM)和条件线性 LCM 进行了数据分析。典型模式的拟合程度较高。踝围和肌肉质量等因素影响了模型截距。踝围越大,表明从肌腱到皮肤表面的信号传输衰减,导致生物信号值越低。 这些结果表明,使用压电薄膜传感器可以捕捉到脚踝附近肌腱的生物信号。有研究将来自肌腱的生物信号定义为机械伸展图。研究表明,源自肌腱的生物信号与施加的肌肉力量之间的关系可以线性解释。这项研究的启示可能有助于运动控制和康复领域的个性化方法。阐明生物信号产生机制的生理学研究是必要的。
