The effects of treadmill workstation use on kinematic gait symmetry and computer work performance remain unclear. The purpose of this pilot study was to analyze the effects of treadmill workstation use on lower body motion symmetry while performing a typing task when compared to overground and treadmill walking. The lower body motion of ten healthy adults (6 males and 4 females) was recorded by a motion capture system. Hip, knee, and ankle joint rotations were computed and compared for each condition. Despite comparable lower body kinematic gait asymmetries across conditions, asymmetric knee flexion motions at early gait cycle were only found in treadmill workstation users (left knee significantly more flexed than the right one). This demonstrates that the interaction between walking and another task is dependent on the task cognitive content. Our findings suggest that lower body kinematic gait symmetry may be influenced by the use of treadmill workstations.

The purpose of this study was to determine the performance of employees (ASN) in the South Morotai District office. The form of this research is descriptive qualitative, with data collection techniques through observation and in-depth interviews with the subdistrict head, subdistrict head secretary, employees, and the community. This study concluded that employees at the South Morotai District Office were not disciplined in terms of time, both when they entered the office and after working hours. Employees are not able to make the best use of time to do productive work to improve performance. employees generally do not know and understand their respective fields of duty. The concept of the right man in the right place is not applied in the placement of employees. Performance evaluation of employees at the South Morotai District Office is difficult because of unclear job descriptions and division of tasks for the state apparatus. This causes the work performance is not measurable both in quality and quantity..

Background: Every working woman has the right to continue to live as a healthy individual. The working environment has important effects on general health status and reproductive health of women. If menopouse period of women is not taken into consideration and if appropriate arrangements are not made at workplaces, their work performance and productivity decrease. It is important to have detailed knowledge about factors creating risk for health in order to develop effective policies and programs directed towards preventing them. Objective: This study was performed to determine perceived effects of menopause on work life and attitudes of an institution towards menopausal women. Methods: The study population included 419 women aged 45-55 years and working at a university. Out of 419 women, 291 could be contacted. Data were collected with a questionaire composed of questions about descriptive characteristics, effects of menopause on work life and support from and attitudes of the institution about menopause. Data collected to reveal menopausal women’s experiences at work were analyzed with statistical methods frequency, percentages and mean. Results: The mean age at which menopause started was 47 years and 89.7% of the women experienced menopausal complaints. Conclusions: Physical conditions at work and stressors were found to increase menopausal complaints and had a negative effect on work performance.

We examined the relationships between change of direction (COD) speed and deficit, and a series of speed- and power-related measurements in national team rugby union players and analyzed the influence of movement patterns on COD ability. Eleven male athletes completed the following physical assessments on different days: day 1—anthropometric measurements, and lower-body kinematic parameters (assessed with eight inertial sensors) and completion time in COD tests (pro-agility, 45° cutting maneuver (CUT), and “L” (L-Drill)); day 2—bilateral and unilateral squat and countermovement jumps, 40 m linear sprint, and bar-power output in the jump squat and half-squat exercises. Pearson’s product–moment correlations were performed to determine the relationships between COD velocities, COD deficits, and the speed–power variables. Differences between players with higher and lower COD deficits were examined using magnitude-based inferences. Results showed that (1) greater sprint momentum was associated with higher COD deficits, particularly in drills with sharper angles and multiple directional changes (L-drill and pro-agility); (2) higher unilateral jump heights were associated with greater COD deficits in the pro-agility and L-drill but not in the CUT; (3) faster athletes were less efficient at changing direction and presented greater trunk and knee flexion angles during COD maneuvers, probably as a consequence of higher inertia.

Objectives: This study aims to determine femoral cartilage thickness using ultrasonography in familial Mediterranean fever (FMF). Patients and methods: A total of 45 patients (16 males, 29 females; mean age: 38.5±9.1 years; range, 24 to 49 years) with the diagnosis of FMF and 31 healthy individuals (6 males, 25 females; mean age: 37.0±8.7 years; range, 25 to 47 years) between January 2016 and July 2016 were included in this study. Clinical data and demographic characteristics of the patients were recorded. All FMF cases in the study were in remission with colchicine treatment. The thickness of femoral cartilage in both knees were evaluated using ultrasonography. Three measurements (mid-point) were taken from both knees (at the medial/lateral femoral condyles and intercondylar area). Results: Ultrasonographical measurements revealed that cartilage measurements of FMF patients were significantly thinner at both the medial/lateral femoral condyles and intercondylar area on the right knee and at the medial/lateral femoral condyles on the left knee (p<0.001). The cartilage measurements in FMF patients were significantly thinner at the intercondylar area on left knee, compared to those in controls (p=0.023). Conclusion: Our study showed decreased femoral cartilage thickness in FMF patients. These findings indicate that even if these patients do not have an attack, they may have subacute and chronic arthritis in their joints, and their femoral cartilage thickness can be affected.

Introduction Glucocorticosteroid injections have been widely used in clinical practice. Betamethasone is one of the agents of this group of drugs. Its efficacy and therapeutic effect with intra-articular administration are undeniable. There are special instructions on the dosage and frequency of use of the drug but unfortunately there are cases of its wrong administration. There is also an evidence of an adverse effect on cartilage both of the drug itself and its combination with local anesthetics. Aim Evaluation of the results of different weekly intra-articular protocols of betamethasone administration on histological preparations of rabbit knee joints. Methods Histological preparations of the right knee joints of three groups of rabbits were studied: after one, three, and six administrations of betamethason per week and the control intact left knee joints. Results Histological preparations of the control group and the group with a single weekly administration of the drug did not have any changes in the structure of diarthrosis. Dystrophic and necrotic changes affecting all morphological components were observed in the joints of animals that received intra-articular injections of betamethason three times a week (compared to a single injection, the area of dystrophy and necrosis of the cartilage was greater by 10.05 ± 0.75 % (p < 0.05), of subchondral bone by 8.11 ± 0.5 % (p < 0.001), and of synovium by 6.25 ± 0.32 % (p < 0.05). The group with six injections of the drug per week had the most pronounced changes. The area of necrotic changes of the cartilage was greater by 6.39 ± 0.75 % than in the group with three injections per week (p < 0.001), of subchondral bone by 11.18 ± 0.5 % (p < 0.001), of synovium by 6.12 ± 0.32 % (p < 0.001). Discussion Inflammatory cell infiltration of joint structures was absent in all cases. It indicates an aseptic nature of tissue necrosis. Evidence has been obtained between the increase in the frequency of intra-articular injections of betamethasone and the severity of dystrophic and necrotic changes in all morphological components of the joint.

Prolong computer work without proper ergonomics can lead to neck pain which ultimately causes serious problems like muscle imbalance, headache, poor work performance. The purpose of this study is not only to promote awareness of correct exercise regime and to compare two exercise interventions in improvement of neck pain, also effect of these regimes on nine different components of daily living activities like headache, work performance, concentration. Experimental, Randomized control trail (RCT) 68 participants took part in the study and were divided randomly into two groups. Group one received cranio- cervical (CC) regime of 06 weeks and second group was given treatment in 2 stages. First stage comprise of minimum repetition exercise which was upgraded to three set with weight in second stage. The chief impact was seen as the reduction of pain intensity in both interventions. Subjects with neck pain of both groups proven a change in neck pain pre Neck Disability Index (NDI) mean of CC, group01 (mean 19.18, std 5.2, p<0.05), and post NDI score of CC group 01 (mean=6.18,std=6, p<0.05) while in strength endurance (SE) group pre-score (mean=18.6, std=6.3, p<0.05) And post NDI score (mean=7,std=6, p<0.05) . Both groups proved significant reduction in neck pain. This study showed that participant who had received cranio-cervical regime and strength endurance training significantly improves their work performance as well as neck pain. However, CC group showed improvement regarding work performance and headache while SE group demonstrated significant improvement in weight lifting than second group.

Background: The fabella, which is generally located in the lateral head of the gastrocnemius muscle, is a sesamoid bone that articulates with the posterior face of the lateral femoral condyle. As traditional information, the prevalence of fabella is between 10–30% in the population and is usually present in both knees. Introduction: The objective of this study was to investigate the knee MRIs in the Eastern Anatolia Region of Turkey subjects in order to assess the prevalence of the fabella and analyse the differences between gender, age and laterality and its symmetry pattern. Methods: This study was a retrospective study in patients older than 18 years whose knee MRIs were taken between February 2014 and February 2016. In this study, a total of 531 patients [290 females and 241 males] were included. The radiographs were examined by two orthopedic surgeons and the fabella was located. Later, an expert radiologist made the final decision and confirmed the results. Results: The number of patients included in the study was 531. We detected os fabella in 59 (11.1%) patients. Of the 59 os fabella, 33 were in the right knee and 26 were in the left knee, 38 were female and 21were male. Conclusion: In this study, we investigated the age and gender differences besides the prevalence and the symmetry pattern of the fabella in the Eastern Anatolia Region of Turkey’s population. Prevalence of the fabella was found to be 11.1% which is different than previously published studies.

Abstract Background Catheter-related right atrial thrombosis is a rare, but potentially life threatening complication in patients with central venous catheters (CVCs). Echocardiography is an indispensable tool in the diagnosis of right atrial thrombosis. We present a case of a young man with lymphoma, Staphylococcus aureus sepsis and a peripherally inserted central catheter (PICC) who had a septic thrombus in the right atrium. Case summary A 23-year-old male patient with recently diagnosed Hodgkin’s lymphoma had an inserted PICC for the purpose of chemotherapy application. Three days after the first chemotherapy application a thrombosis of the cephalic and subclavian veins at the site of PICC was found. The PICC was removed and the patient was treated with therapeutic doses of dalteparin. A day after the discovery of thrombosis, the patient became clinically septic, with high inflammatory markers and Staphylococcus aureus was isolated from his blood cultures. He was promptly treated with flucloxacillin. Due to pain in his left knee, a knee puncture was performed, and Staphylococcus aureus was isolated also from the knee synovial fluid. A transthoracic echocardiography revealed a 2.8 x 2.8 cm sessile thrombus on the lateral wall of the right atrium. There were no vegetations on the tricuspid or other valves. Due to increasing pain in his left knee and an increase in inflammatory markers a synovectomy was performed. After the operation the clinical status improved and the inflammatory parameters decreased. A magnetic resonance imaging of the heart was performed, which confirmed the thrombus described by echocardiography and excluded the presence of abscesses. All the time the patient was treated in the intensive care unit with standard heparin, flucloxacillin, and piperacillin/tazobactam due to neutropenia. The inflammatory markers slowly decreased and all further blood cultures were negative. Follow-up echocardiography after 16 days of antibiotic and anticoagulant therapy revealed that the mass in the right atrium, attached on the lateral atrium wall, was slightly smaller than before. The mass was centrally un-echogenic with echogenic cover, appearing as a partial regression of the septic thrombus with a central colliquation. The heart valves remained free of vegetations. There was a minor pericardial effusion, with no signs of constriction. Due to improved clinical status the patient was able to start with chemotherapy again after a pause of three weeks. Conclusion The patient had three important risk factors for thrombosis: PICC, sepsis and malignancy. Echocardiography is an important tool for mass diagnosis and the exclusion of vegetations in a septic patient. Often there is a need for further specification of the mass etiology or for the exclusion of other pathology, like abscesses in our case. Magnetic resonance is an important tool that can complement the echocardiographic examination. Abstract P1498 Figure. Right atrial thrombus

The article is devoted to the determination of second-order perturbations in rectangular coordinates and components of the body motion to be under study. The main difficulty in solving this problem was the choice of a system of differential equations of perturbed motion, the coefficients of the projections of the perturbing acceleration are entire functions with respect to the independent regularizing variable. This circumstance allows constructing a unified algorithm for determining perturbations of the second and higher order in the form of finite polynomials with respect to some regularizing variables that are selected at each stage of approximation. The number of approximations is determined by the given accuracy. It is rigorously proven that the introduction of a new regularizing variable provides a representation of the right-hand sides of the system of differential equations of perturbed motion by finite polynomials. Special points are used to reduce the degree of approximating polynomials, as well as to choose regularizing variables.
