Quantification of upper extremity movement is a common objective in both research and clinical practice. Currently, methods based on angle-angle diagrams, also called cyclograms, seem to be promising. Nevertheless, compared to the study of lower limbs, the concept of angle-angle diagrams has not been systematically used to study upper limb movements during walking. The paper describes two examples of new methods based on angle-angle diagrams for application in rehabilitation and assistive robotics. The cyclograms represent information about the relationship between the angles and their changes over time. We used cyclograms as patterns for learning artificial neural networks and predicting the movement of upper-limb. Together with artificial intelligence, cyclograms offer wide scope of application in prosthesis control systems. Using bilateral cyclogram, the information about the relationship between the right and left arm joint angles is used to evaluate the symmetry of movements. The method based on the orientation of the bilateral cyclogram can be used as an additional method for determining the symmetry of movements of the upper limbs or exo-prosthesis.
上肢运动的量化是研究和临床实践的共同目标。目前,基于角-角图(也称为环图)的方法似乎很有前途。然而,与对下肢的研究相比,角度图的概念尚未系统地用于研究行走过程中上肢的运动。本文介绍了两个基于角度图的新方法在康复和辅助机器人中的应用实例。环线图表示角度之间的关系及其随时间变化的信息。我们使用环图作为学习人工神经网络和预测上肢运动的模式。与人工智能一起,环图在假肢控制系统中有广泛的应用。利用双侧环图,利用左臂和右臂关节角度之间的关系信息来评价运动的对称性。基于双侧环图方向的方法可作为确定上肢或外假体运动对称性的附加方法。

Venous thromboembolism (VTE) causes considerable morbidity and mortality. About half of all VTE cases in adults are related to recent hospitalization, in spite of the clinical guidelines regarding prophylaxis. We aimed to assess the frequency and the independent risk factors in VTE in hospitalized patients, and to compare the risk factors in medical versus surgical cases. A case-control study consisting of 732 patients (382 with VTE and 350 controls) was designed. At least one risk factor was found in 90.31% of VTE cases; more than half of the patients presented multiple risk factors, associated with a double risk comparatively to the intervention of only one factor. A similar distribution of the risk factors was found in both medical and surgical patients, except for congestive cardiac failure (predominant in medical cases) and respectively, varicose veins, previous episode of VTE and cancer (predominant in surgical VTE patients). The independent risk factors in VTE were the following: previous episode of VTE, obesity, chronic obstructive pulmonary disease, congestive cardiac failure, varicose veins and cancer. The study shows the importance of the risk factors in VTE and the need to detect hospitalized patients at risk in both medical and surgical cases.
静脉血栓栓塞(VTE)引起相当高的发病率和死亡率。尽管有关于预防的临床指南,但大约一半的成人静脉血栓栓塞病例与近期住院有关。我们的目的是评估住院患者静脉血栓栓塞的频率和独立危险因素,并比较内科和外科病例的危险因素。设计了一项由732例患者(382例静脉血栓栓塞患者和350例对照组)组成的病例对照研究。90.31%的静脉血栓栓塞病例至少存在一种危险因素;超过一半的患者存在多重危险因素,与单因素干预相比存在双重危险。在内科和外科患者中发现了类似的风险因素分布,除了充血性心力衰竭(主要是内科病例)和静脉曲张、静脉血栓栓塞和癌症(主要是外科静脉血栓栓塞患者)。静脉血栓栓塞的独立危险因素有:静脉血栓栓塞病史、肥胖、慢性阻塞性肺疾病、充血性心力衰竭、静脉曲张和癌症。该研究显示了静脉血栓栓塞危险因素的重要性,以及在内科和外科病例中发现有危险的住院患者的必要性。

The article focuses on the eruption of palmoplantar pustular psoriasis, which was documented in a 53-year-old man diagnosed with prostate cancer with bone metastases. This clinical finding was made during routine hormone therapy and palliative radiotherapy. The local improvement in skin lesions was achieved following administration of topical ointments and the use of UVA 311 nm radiation therapy. The management of prostate cancer in this subject resulted in malaise, onset of diabetes mellitus and increased concentration of serum lipids. Interestingly, a few days after the statin treatment was initiated, the intensive pustule eruption was observed as well as severe pain and burning sensation in the palms and soles. The dermatological treatment led to significant improvement. The patient is still receiving oncological therapy and is monitored by dermatologists on a regular basis.
本文的重点是掌跖脓疱性银屑病的爆发,这是记录在一个53岁的男性诊断为前列腺癌骨转移。这一临床发现是在常规激素治疗和姑息性放疗期间发现的。局部皮肤病变的改善是在给予局部软膏和使用UVA 311 nm放射治疗后实现的。前列腺癌的治疗导致患者出现不适、糖尿病发作和血脂浓度升高。有趣的是,在他汀类药物治疗开始几天后,观察到强烈的脓疱爆发以及手掌和脚底的剧烈疼痛和烧灼感。皮肤病学治疗显著改善。患者仍在接受肿瘤治疗,并由皮肤科医生定期监测。

Although it is accepted that an important correlation exists between the physical exercise and the oxidative stress status, the data regarding the levels of the main oxidative stress markers after physical training have been difficult to interpret and a subject of many controversies. There are also very few studies regarding the effects of short-time exercise on the oxidative stress status modifications. Thus, in the present report we were interested in studying the modifications of some oxidative stress markers (two antioxidant enzymes-superoxide dismutase and glutathione peroxidase, a lipid peroxidation parameter — malondyaldehide, the total antioxidant status and protein carbonyl levels), from the serum of rats that were subject to one bout of five minutes exercise on a treadmill, when compared to a control sedentary group. In this way, we observed a decrease of superoxide dismutase specific activity in the rats which performed the exercises. Still, no modifications of glutathione peroxidase specific activity were found between groups. In addition, increased levels of malondyaldehide and protein carbonyls were observed in the rats subjected to exercises. In conclusion, our data provides new evidence regarding the increase of the oxidative stress status, as a result of a 5-minutes bout of treadmill exercising in rats, expressed through a decrease in the SOD specific activity and the total antioxidant status and also an increase of the lipid peroxidation and protein oxidation processes.
虽然人们普遍认为体育锻炼与氧化应激状态之间存在重要的相关性,但关于体育锻炼后主要氧化应激标志物水平的数据一直难以解释,并且存在许多争议。关于短时间运动对氧化应激状态改变影响的研究也很少。因此,在本报告中,我们对研究一些氧化应激标记物(两种抗氧化酶-超氧化物歧化酶和谷胱甘肽过氧化物酶,脂质过氧化参数-丙二醛脂,总抗氧化状态和蛋白质羰基水平)的变化感兴趣,这些变化来自于在跑步机上进行一次五分钟运动的大鼠的血清,与对照组相比。通过这种方法,我们观察到进行运动的大鼠的超氧化物歧化酶特异性活性降低。然而,在两组之间没有发现谷胱甘肽过氧化物酶特异性活性的变化。此外,在运动的大鼠中观察到丙二醛脂和蛋白质羰基的水平增加。综上所述,我们的数据为大鼠在5分钟的跑步机运动后氧化应激状态的增加提供了新的证据,表现为SOD特异性活性和总抗氧化状态的降低,以及脂质过氧化和蛋白质氧化过程的增加。

A case of renal arteriovenous fistula between the main renal artery and interlobar vein diagnosed 25 years after percutaneous renal biopsy was presented. A 62-year-old female was referred to a urologist with dilatation of the left renal pyelocalyceal system diagnosed after abdominal ultrasonography, while intravenous urography did not confirm that finding. Historically, she underwent renal biopsy 25 years ago without any complication. Her hypertension was well controlled during the last 10 years, although three antihypertensive drugs with occasional additional diuretics were necessary during the last 6 months. Color Duplex Ultrasonography, arteriography and Multi-Slice Computed Tomography revealed the presence of renal arteriovenous fistula between the main renal artery and interlobar vein, as well as severe dilatation of all interlobar veins, renal, ovarian and adrenal vein on the left side. Urological and vascular surgeons operated to ligate the fistula and preserve the kidney. However, it was not possible to reach the fistula inside the kidney and nephrectomy was performed.
本文报告一例经皮肾活检25年后诊断为肾主动脉与叶间静脉之间的肾动静脉瘘。一名62岁的女性在腹部超声检查后被诊断为左肾盂肾盂系统扩张,而静脉尿路造影未证实这一发现。历史上,她在25年前接受了肾活检,没有任何并发症。在过去的10年里,她的高血压得到了很好的控制,尽管在过去的6个月里,她需要服用三种降压药和偶尔额外的利尿剂。彩色双超、动脉造影及多层ct示肾主动脉与叶间静脉间存在肾动静脉瘘,左侧所有叶间静脉、肾静脉、卵巢静脉及肾上腺静脉均严重扩张。泌尿外科和血管外科手术结扎瘘管并保存肾脏。然而,由于无法到达肾脏内的瘘管,因此进行了肾脏切除术。

Lung cancer is rated with the highest incidence and mortality every year compared with other forms of cancer, therefore early detection and diagnosis is essential. Artificial Neural Networks (ANNs) are “artificial intelligence” software which have been used to assess a few prognostic situations. In this study, a database containing 193 patients from Diagnostic and Monitoring of Tuberculosis and Illness of Lungs Ward in Kuyavia and Pomerania Centre of the Pulmonology (Bydgoszcz, Poland) was analysed using ANNs. Each patient was described using 48 factors (i.e. age, sex, data of patient history, results from medical examinations etc.) and, as an output value, the expected presence of lung cancer was established. All 48 features were retrospectively collected and the database was divided into a training set (n=97), testing set (n=48) and a validating set (n=48). The best prediction score of the ANN model (MLP 48-9-2) was above 0.99 of the area under a receiver operator characteristic (ROC) curve. The ANNs were able to correctly classify 47 out of 48 test cases. These data suggest that Artificial Neural Networks can be used in prognosis of lung cancer and could help the physician in diagnosis of patients with the suspicion of lung cancer.
与其他形式的癌症相比,肺癌每年的发病率和死亡率最高,因此早期发现和诊断至关重要。人工神经网络(ann)是一种“人工智能”软件,已被用于评估一些预测情况。在这项研究中,使用人工神经网络分析了库亚维亚和波美拉尼亚肺病中心(比得哥什,波兰)肺结核和肺病诊断和监测病房193名患者的数据库。每个患者使用48个因素(即年龄、性别、患者病史数据、医学检查结果等)进行描述,并作为输出值确定肺癌的预期存在。回顾性收集所有48个特征,并将数据库分为训练集(n=97)、测试集(n=48)和验证集(n=48)。人工神经网络模型(MLP 48-9-2)的最佳预测分数为受试者操作特征曲线下面积的0.99以上。人工神经网络能够正确分类48个测试用例中的47个。这些数据表明,人工神经网络可以用于肺癌的预后,并可以帮助医生对疑似肺癌患者进行诊断。

These data suggest that Artificial Neural Networks can be used in prognosis of lung cancer and could help the physician in diagnosis of patients with the suspicion of lung cancer.","PeriodicalId":50709,"journal":{"name":"Central European Journal of Medicine","volume":"15 1","pages":"632-641"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2478/s11536-013-0327-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68851979","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}

IntroductionThe future burden of cancer deaths will be the effect of demography changes and the influence of the risk factors. Goal. Making prognosis of number of cancer deaths in Poland in 2020.MethodologyThese predictions of number of cancer deaths in 2020 (all cancers and the most frequent cancers for men and women) has been based on the historical trends of cancer mortality in Poland in 2001–2010 and the demographical prognosis made by Central Statistical Office using the method of Hakulinen and Dyba.ResultsThere will be 58 147 cancer deaths in men and 45 970 deaths in women in 2020. Compare to the period 2006–2010 the number of cancer deaths in Poland will increase by 12.0% for men and by 13.9% for women. In 2020 the big increase in number of deaths of melanoma skin cancer and multiple myeloma for both sexes, colorectal and pancreatic cancers for men and lung, endometrial and brain cancers for women will be observed.ConclusionsThe predicted increase in number of cancer deaths for Poland in 2020 will be the results of: the demographical changes, changes of the cancer risk factors, the participation in the screening programs and treatment improvement.
未来癌症死亡负担将受到人口结构变化和危险因素的影响。的目标。对2020年波兰癌症死亡人数进行预测。方法:对2020年癌症死亡人数(男性和女性的所有癌症和最常见癌症)的预测是根据2001-2010年波兰癌症死亡率的历史趋势以及中央统计局使用Hakulinen和Dyba方法作出的人口预测。结果2020年男性癌症死亡人数为58147人,女性癌症死亡人数为45970人。与2006-2010年期间相比,波兰男性癌症死亡人数将增加12.0%,女性增加13.9%。2020年,将观察到两性黑色素瘤、皮肤癌和多发性骨髓瘤、男性结肠直肠癌和胰腺癌以及女性肺癌、子宫内膜癌和脑癌的死亡人数大幅增加。结论波兰2020年癌症死亡人数的预测增长将是人口结构变化、癌症危险因素变化、参与筛查计划和治疗改善的结果。
