A Method of Optical Grooming Based on Dynamic Multicast Capable of Adaptive Splitting Under Differential Delay Constraint
Authors: Zheng Danling , Wu Lan , Liu Huanlin 
Published: January 2017

Abstract
Aiming at the problem of energy efficient transmission for multiple paths under differential delay constraint, we propose a method of optical grooming based on dynamic splitting under differential delay constraint algorithm (OG-DSDA) for optical networks. When a multicast demand cannot be groomed due to the bandwidth fragment, the method constructs two types of logic light-tree sets according to the differential delay constraint between source node and destinations. In order to reduce the network link costs caused by too many split parts, the method gives high priority to the first type logic light-trees with the maximum available bandwidth to meet the requirement. When the bandwidth of first type logic light-tree is insufficient for all sub-requests, the rest of sub-demands is adaptively groomed into a light-tree in second set of light-trees with the lower power consumption. Simulation results show that the proposed method can effectively decrease the network blocking probability and reduce network’s energy consumption.

Abstract
The surgical education in Italy has always been a very important issue. The aim of this article is to bring together the feedback of the definitions of the various components of the learning scheme and to evaluate the importance of the legal point.
In March 2016 we performed a literature review. We have also examinated the internet pages of the Italian Department of Education, Health and Medical Order.
In Italy the tutor had an unclear role from a legal point of view. He is the person who must be able to perform a specific procedure with expert technical and who must know how to stop the student if this is about to perform a dangerous maneuver. In Italy the ability to work for the trainee is limited in all reality, it depends on several factors including the increase of numbers of medical-legal disputes, the timing, the commitment it requires mentoring and a lack of mentors.
Conclusion: In surgery, the problem is greater because of the increasingly of medico-legal implications that we are after surgical procedure. It would be necessary to define a role of the tutor in a regular protocol and a proper assessment of his performance.

Published: January 2017

Abstract
The problem of resource management for server virtualization under the limitation of recovery time objective was considered in this paper. Models and methods of workload and resource management of IT infrastructure with server virtualization in terms of time limit for services recovery in case of provision of services by virtual private servers were proposed. Mathematical models for excess and lack of resources was formulated as linear and nonlinear 0-1 programming problems. To solve these problems branch and bound, heuristic and modified genetic algorithms were proposed.
Criterion-Referenced Values of Grip Strength and Usual Gait Speed Using Instrumental Activities of Daily Living Disability as the Criterion
Authors: Lee Meng-Chih , Hsu Chih-Cheng , Tsai Yi-Fen , Chen Ching-Yu , Lin Cheng-Chieh , Wang Ching-Yi 
Published: January 2017

Background and Purpose:
Current evidence suggests that grip strength and usual gait speed (UGS) are important predictors of instrumental activities of daily living (IADL) disability. Knowing the optimum cut points of these tests for discriminating people with and without IADL disability could help clinicians or researchers to better interpret the test results and make medical decisions. The purpose of this study was to determine the cutoff values of grip strength and UGS for best discriminating community-dwelling older adults with and without IADL disability, separately for men and women, and to investigate their association with IADL disability.

Methods:
We conducted secondary data analysis on a national dataset collected in the Sarcopenia and Translational Aging Research in Taiwan (START). The data used in this study consisted of health data of 2420 community-dwelling older adults 65 years and older with no history of stroke and with complete data. IADL disability was defined as at least 1 IADL item scored as “need help” or “unable to perform.” Receiver operating characteristics analysis was used to estimate the optimum grip strength and UGS cut points for best discriminating older adults with/without IADL disability. The association between each physical performance (grip strength and UGS) and IADL disability was assessed with odds ratios (ORs).

Results and Discussion:
With IADL disability as the criterion, the optimal cutoff values of grip strength were 28.7 kg for men and 16.0 kg for women, and those for UGS were 0.76 m/s for men and 0.66 m/s for women. The grip strength test showed satisfactory discriminant validity (area under the curve > 0.7) in men and a strong association with IADL disability (OR > 4). Our cut points using IADL disability as the criterion were close to those indicating frailty or sarcopenia.

Conclusions:
Our reported cutoffs can serve as criterion-referenced values, along with those previously determined using different indicators, and provide important landmarks on the performance continua of older adults' grip strength and UGS. These landmarks could be useful in interpreting test results, monitoring changes in performance, and identifying individuals requiring timely intervention. For identifying older adults at risk of IADL disability, grip strength is superior to UGS.
Influences of Age, Obesity, and Adverse Drug Effects on Balance and Mobility Testing Scores in Ambulatory Older Adults
Authors: Anson Eric , Thompson Elizabeth , Odle Brian L. , Jeka John , Walls Zachary F. , Panus Peter C. 
Published: January 2017

Background and Purpose:
The adverse effects of drugs may influence results on tests of mobility and balance, but the drug-specific impact is not identified when using these tests. We propose that a quantitative drug index (QDI) will assist in assessing fall risk based on these tests, when combined with other fall risk variables.

Methods:
Fifty-seven community-dwelling older adults who could walk independently on a treadmill and had Mini-Mental State Examination (MMSE) scores equal to or greater than 24 participated. Mobility and balance outcome measures included the Balance Evaluation Systems Test (BESTest), Berg Balance Scale (BBS), Timed Up and Go (TUG) and cognitive dual task TUG (TUGc). Fall history, current drug list, and Activity-Specific Balance Confidence (ABC) scale scores were also collected. Body mass index (BMI) was calculated. The QDI was derived from the drug list for each individual, and based on fall-related drug adverse effects. Multiple linear regression analyses were conducted using age, BMI, and QDI as predictor variables for determining mobility and balance test scores, and ABC scale scores. Subsequently, participants were divided into (QDI = 0) low-impact drug group (LIDG) and (QDI > 0) high-impact drug group (HIDG) for Mann-Whitney 2-group comparisons.

Results:
Age, BMI, and QDI were all significant (P < .001) independent variables in multiple regression analyses for mobility and balance test scores, but not for the ABC scale. Separately, the 2 group comparisons for the BESTest, BBS, TUG, and TUGc demonstrated that HIDG scored significantly (P < .05) worse on these tests compared with the LIDG. Drug counts were also significantly higher for the HIDG than for the LIDG. In contrast, age, BMI, MMSE, and reported falls in the last 12 months were not significantly different between groups.

Conclusion:
Age, BMI, and QDI—all contributed independently to the mobility and balance test scores examined, and may provide health care professionals a screening tool to determine whether additional mobility and balance testing is required. In addition, the QDI is a more precise marker of adverse effects of drugs compared with drug counts, as the latter does not quantitate the influence of drugs on physiologic function.
Encoding of Both Reaching and Grasping Kinematics in Dorsal and Ventral Premotor Cortices

Published: January 2017

Classically, it has been hypothesized that reach-to-grasp movements arise from two discrete parietofrontal cortical networks. As part of these networks, the dorsal premotor cortex (PMd) has been implicated in the control of reaching movements of the arm, whereas the ventral premotor cortex (PMv) has been associated with the control of grasping movements of the hand. Recent studies have shown that such a strict delineation of function along anatomical boundaries is unlikely, partly because reaching to different locations can alter distal hand kinematics and grasping different objects can affect kinematics of the proximal arm. Here, we used chronically implanted multielectrode arrays to record unit-spiking activity in both PMd and PMv simultaneously while rhesus macaques engaged in a reach-to-grasp task. Generalized linear models were used to predict the spiking activity of cells in both areas as a function of different kinematic parameters, as well as spike history. To account for the influence of reaching on hand kinematics and vice versa, we applied demixed principal components analysis to define kinematics synergies that maximized variance across either different object locations or grip types. We found that single cells in both PMd and PMv encode the kinematics of both reaching and grasping synergies, suggesting that this classical division of reach and grasp in PMd and PMv, respectively, does not accurately reflect the encoding preferences of cells in those areas.SIGNIFICANCE STATEMENTFor reach-to-grasp movements, the dorsal premotor cortex (PMd) has been implicated in the control of reaching movements of the arm, whereas the ventral premotor cortex (PMv) has been associated with the control of grasping movements of the hand. We recorded unit-spiking activity in PMd and PMv simultaneously while macaques performed a reach-to-grasp task. We modeled the spiking activity of neurons as a function of kinematic parameters and spike history. We applied demixed principal components analysis to define kinematics synergies. We found that single units in both PMd and PMv encode the kinematics of both reaching and grasping synergies, suggesting that the division of reach and grasp in PMd and PMv, respectively, cannot be made based on their encoding properties.

Objective
Acromegaly is a rare disease caused by excess growth hormone (GH) production by the pituitary adenoma. The skeletal complications of GH and IGF-1 excess include increased bone turnover, increased cortical bone mass and deteriorated microarchitecture of trabecular bone, associated with a high risk of vertebral fractures in the presence of relatively normal bone mineral density (BMD). We aimed to evaluate tissue-level properties of bone using impact microindentation (IMI) in well-controlled patients with acromegaly aged ≥18 years compared to 44 controls from the outpatient clinic of the Centre for Bone Quality.

Design and methods
In this cross-sectional study, bone material strength index (BMSi) was measured in 48 acromegaly patients and 44 controls with impact microindentation using the osteoprobe.

Results
Mean age of acromegaly patients (54% male) was 60.2 years (range 37.9–76.5), and 60.5 years (range 39.8–78.6) in controls (50% male). Patients with acromegaly and control patients had comparable BMI (28.2 kg/m2 ± 4.7 vs 26.6 kg/m2 ± 4.3, P = 0.087) and comparable BMD at the lumbar spine (1.04 g/cm2 ± 0.21 vs 1.03 g/cm2 ± 0.13, P = 0.850) and at the femoral neck (0.84 g/cm2 ± 0.16 vs 0.80 g/cm2 ± 0.09, P = 0.246). BMSi was significantly lower in acromegaly patients than that in controls (79.4 ± 0.7 vs 83.2 ± 0.7; P < 0.001).

Conclusion
Our data indicates that tissue-level properties of cortical bone are significantly altered in patients with controlled acromegaly after reversal of long-term exposure to pathologically high GH and IGF-1 levels. Our findings also suggest that methods other than DXA should be considered to evaluate bone fragility in patients with acromegaly.

A qualitative exploration of the characteristics and practices of interdisciplinary collaboration
Authors: West Maria , Boshoff Kobie , Stewart Hugh 
Published: January 2017

The Children's Centres in South Australia are examples of settings requiring the effective collaboration of disciplines from diverse backgrounds, such as staff from education, health and welfare. Working together across different professional groups is complex and challenging. Existing literature describing collaboration in early childhood settings focuses on exploring the concept from a single professional perspective, with limited exploration from multiple professional perspectives. The aim of this study was to describe the characteristics and practices of collaboration in well-established Children's Centre teams from multiple professional perspectives. It is anticipated that this description can result in strategies for other teams in similar interdisciplinary settings. A systematic review was conducted summarising the literature on the characteristics and practices of collaboration in Children's Centres, followed by a descriptive qualitative study. Team members from two centres participated in focus groups, thematic analysis was undertaken and findings of both phases were integrated.
Characteristics and practices that support constructive teamwork were identified, with the central theme of leadership and the interrelated sub-themes including: development of team cohesiveness; supportive team processes, as well as working within and between government departments. The study contributes to the understanding of the complexity and inter-relatedness of the characteristics and processes involved in collaboration, highlighting the importance of leaders in supporting the collaboration of disciplines from different professional backgrounds.

Note despre numele proprii în traducerile românești din secolul al XVIII-lea ale Vieții lui Petru (de Antonio Catiforo)
Authors: Ungureanu Cristian 
Published: January 2017

Vita di Pietro este o lucrare alcătuită de grecul Antonio Catiforo în limba italiană, publicată la Veneția, în 1736; o versiune a sa în limba greacă a fost publicată tot la Veneția, un an mai tîrziu, de către Alexandros Kankellarios. Lucrarea conține șase cărți și sintetizează informațiile oferite de surse referitoare la epoca și personalitatea țarului rus. În română, ea a cunoscut mai multe traduceri la jumătatea și în a doua perioadă a secolului al XVIII-lea, în toate cele trei provincii românești. Numărul mare de copii arată interesul de care s-a bucurat această lucrare în epocă.
Articolul de față prezintă cîteva particularități ale transferului numelor proprii din limba-sursă în limba-țintă. Am analizat patru tipuri de nume proprii: horonimul Moscovia și etnonimul aferent, horonime occidentale, antroponime rusești, antroponime de alte origini, urmărind felul în care traducătorii se raportează la sursă și diferențele dintre versiuni din acest punct de vedere.

Trochanteric Femoral Fracture Around a Birmingham Hip Resurfacing Prosthesis
Authors: Chou Daud Tai Shan , Davis Ben 
Published: January 2017

Case:
A traumatic nondisplaced periprosthetic trochanteric fracture around a well-fixed and functioning Birmingham Hip Resurfacing prosthesis was managed with a reconstruction intramedullary nail. The surgical procedure provided excellent pain relief, and the patient was able to mobilize with crutches the day after surgery. Follow-up at 1 year confirmed excellent clinical and radiographic results.

Conclusion:
In a patient with a previously well-functioning hip resurfacing prosthesis, internal fixation rather than revision hip arthroplasty can offer good clinical and radiographic outcomes. The use of a reconstruction intramedullary nail may be a good option for fixing a periprosthetic trochanteric fracture around a Birmingham Hip Resurfacing implant.
