Published: March 2019

Synthetic Aperture Radar (SAR) is an active remote sensing satellite which is able to acquire cloud free images in all weather conditions. It is also capable of night time operation. Sentinel-1 data is one of SAR data which is good for monitoring natural resources in area with high cloud cover throughout the year. Processing the data until mosaic product needs good methods and right procedure. An highlight processes to remove noise through border of GRD data scene necessary to do because the processing chain from raw data into L1 GRD (Ground Range Detected) products were leading to artefacts at the near and far range image borders. The artefacts were not visible at a glance in the raw data but, observable clearly after performing mosaic a sets of data. Some methods to fix the problem are available to use such as common noise removal methods. This paper analysed methods to do noise removal i.e. using a tool in ESA’s provided Sentinel-1 software (Sentinel Application Platform - SNAP) and proposed noise removal method using simple thresholding and segmentation process. The mosaic products results from both method shown good results visually but the detailed histogram shown that the S-1 Remove GRD Border Noise results still have a very low value pixels in the black-fill area while the Random Noise Removal removed all of the noise. PSNR of raw data mosaic, GRD Border Noise and Random Noise Removal results sequentially 8.5, 18.6 and 19.7 dB indicated that Random Noise Removal get the highest similarity to reference data.

Hasty changes occurred in the land use and land cover of Coimbatore city corporation, Tamil Nadu within 32 years span (1984 - 2016). Agricultural and forest lands are mainly converted into urban areas generally in an unplanned way which is making a change in dynamics of urban sprawl characteristics. The principal aim of this study is to use remote sensing data, geospatial tools to detect, quantify, analyze the urban land use changes of Coimbatore city, located in the western part of the Tamil Nadu. This study emphases on urban growth analyses and urban sprawl of Coimbatore city. In 2016, the jurisdiction of the Coimbatore Corporation was increased from 72 to 100 wards and five zones which consist area of 365.74Sq.Km. The corporation limit was extended from 29.25Sq.Km. in 1984 to 365.74 Sq. Km. in 2016 which has a growth of 1150 percent area of 1984. Various GIS layers such as Ward, Zone, Corporation boundaries, Road and railway network, Waterbody, Stream, Major locations and Land use / land cover including built-up area; agricultural land; water bodies; industrial area; educational area, and Public & Semi-public area were generated from Coimbatore Corporation map and Remote sensing imagery. This study revealed that Land use/Land cover areas such as agricultural, commercial, educational, industrial, public and semi-public, residential areas and water bodies occupied 9.38, 2.20, 5.0, 3.1, 1.02, 77.37 and 1.93 percentage areas of the city respectively in the year 2016. Land use pattern change was confirmed by field verification study in some places like near Gandhipuram, Brooke Fields, Avinashi Road, etc.

Published: March 2019

A precise forecast of stock price indexes may return a profit for investors. According to CNN Money, in the same month, as much as 93% of global investors have lost money for trading stock. One of the stock price indexes is the stock composite index. Exact predictions of the stock composite index can be critical for creating powerful market exchanging strategies. In this paper, a modified supervised learning method used to solve regression problems, Fuzzy Support Vector Regression (FSVR) is focused. As the complexity of many factors influences the movement of stock price prediction, the prediction results of Support Vector Regression (SVR) cannot always meet people with precision. Thus, this study implies Fuzzy Support Vector Regression (FSVR) stock prediction model, in which fuzzy membership with mapping function is employed to generate a precise price fluctuation of stock. To assure the use of features on model prediction, Fisher Score is used to find high-quality features that can enhance the accuracy. Indonesia Composite Index or Jakarta Composite Index (JKSE) is considered as input data and the result showed that Fisher Score could be applied as feature selection on Indonesia Composite Index prediction with the best model is eleven out of fifteen features with 80% of training data with 0.043529error.

O violão na agenda musical carioca oitocentista
Authors: Taborda Marcia
Published: March 2019

Introduzido no Brasil em princípios do século XIX, com uma ampla aceitação pela elite econômica e social do período, o violão foi praticado em espaços privilegiados, como o Palácio da Quinta da Boa Vista, nos exercícios musicais diários da Imperatriz Leopoldina. A partir da década de 1840, nas mãos de artistas estrangeiros que fomentaram o desenvolvimento da vida cultural carioca oitocentista, a agenda de apresentações musicais permitiu conhecer o repertório destinado ao instrumento, composto de obras originais e sobretudo de transcrições de árias de óperas. Essas características fizeram ressaltar o contraponto que o advento da República imprimiu à imagem do instrumento na sociedade brasileira, altamente negativa, o que se deveu à infalível associação do violão às práticas culturais dos pobres urbanos.
Cross-Table Lateral Radiographs Accurately Predict Displacement in Valgus-Impacted Femoral Neck Fractures
Authors: Temmesfeld Max J. , Dolatowski Filip C. , Borthne Arne , Utvåg Stein Erik , Hoelsbrekken Sigurd Erik
Published: March 2019

Background:

Femoral neck fractures are classified as nondisplaced (Garden types I and II) or displaced (Garden types III and IV) on the basis of anteroposterior radiographs. Cross-table lateral radiographs are important in the assessment of Garden type-I and II fractures as posterior tilt of the femoral head may influence treatment results. A posterior tilt of >20° has been associated with an increased risk of treatment failure after internal fixation, although the precision of these measurements has not been validated. Therefore, the purpose of the present study was to compare cross-table lateral radiographs with 3-dimensional computed tomographic (3D-CT) reconstructions of Garden type-I and II femoral neck fractures.

Methods:

Twenty-three patients presenting with Garden type-I and II femoral neck fractures that were verified on anteroposterior radiographs underwent CT scanning immediately after radiographic examination. 3D models of the fractured and uninjured femora were reconstructed from the CT images, and displacement of the 3D models was determined by superimposing the fractured and uninjured femora. We defined a coordinate system with its origin at the center of the uninjured femoral head with the x axis oriented medially; the y axis, posteriorly; and the z axis, cranially. Correlations between lateral radiographs and 3D models were assessed with the Spearman rank coefficient, mean difference, and limits of agreement.

Results:

Posterior tilt of the femoral head on lateral radiographs was strongly correlated with displacement of the femoral head along the y axis of the 3D models, with a correlation coefficient of 0.86 (p < 0.001). Correlations between the findings on lateral radiographs and displacements along the x or z axis were weak, with coefficients of −0.30 (p = 0.18) and 0.21 (p = 0.34), respectively. The mean difference between displacement on lateral radiographs and displacement along the y axis of the 3D models was smaller, and demonstrated a smaller limits-of-agreement interval, compared with the x or z axis.

Conclusions:

Our results demonstrated a strong correlation between posterior displacement of the femoral head on lateral radiographs and displacement along the y axis in 3D models of Garden type-I and II femoral neck fractures. This finding indicates that lateral radiographs provide an accurate assessment of posterior tilt.
Incidence and Economic Burden of Intertrochanteric Fracture
Authors: Adeyemi Ayoade , Delhougne Gary
Published: March 2019

Background:

There is limited information on current cost estimates associated with intertrochanteric hip fractures in the United States. The purpose of the present study was to estimate the incidence and economic burden of both intertrochanteric and all hip fracture types in the Medicare patient population to the U.S. health-care system.

Methods:

This retrospective database analysis of the 2014 Medicare database involved Standard Analytic File (SAF) 5% sample claims and total enrollment files. Patients ≥65 years of age with a new principal diagnosis of hip fracture (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 820.xy) who were continuously enrolled for 18 months were included; those with intertrochanteric hip fracture were further identified with use of ICD-9-CM code 820.21. The total direct medical costs associated with hip fracture in the 90-day and 12-month post-fracture periods were estimated. The relevant costs were estimated on the basis of a propensity-score-matched analysis. The health-care services responsible for major expenses within the 90-day episode-of-care period were also identified.

Results:

The total annual direct medical costs associated with all hip fractures was $50,508 per patient, resulting in a yearly estimate of $5.96 billion to the U.S. health-care system. Intertrochanteric hip fractures accounted for an annual estimate of $52,512 per patient, corresponding to an overall annual economic burden of $2.63 billion to the U.S. health-care system and representing 44% of all hip fracture costs. Inpatient hospitalization and skilled nursing facility services jointly accounted for 76.3% of the $44,135 estimated cost per patient and 75.6% of the $42,388 estimated cost per patient within the 90-day post-acute care period for intertrochanteric and all hip fractures, respectively.

Conclusions:

Hip fracture represents a substantial economic burden to the U.S. health-care system, accounting for $5.96 billion per year, with intertrochanteric hip fracture accounting for 44% of total costs.

Level of Evidence:

Economic and decision analysis, Level IV. See Instructions for Authors for a complete description of levels of evidence.

Clinical Relevance:

The present study provides a comprehensive and updated annual estimate of the economic burden of all hip fracture types and estimates the economic burden of intertrochanteric hip fractures in the Medicare population; to our knowledge, prior availability of this information in the literature is limited.
Measuring Training Load in Dance: The Construct Validity of Session-RPE
Authors: Surgenor Brenton , Wyon Matthew
Published: March 2019

OBJECTIVE: The session rating of perceived exertion (session-RPE) is a practical and non-invasive method that allows a quantification of internal training load (ITL) in individual and team sports. As yet, no study has investigated its construct validity in dance. This study examines
the convergent validity between the session-RPE method and an objective heart rate (HR)-based method of quantifying the similar ITL in vocational dance students during professional dance training. METHODS: Ten dance students (4 male, 20±1.16 yrs; 6 female, 20±0.52 yrs) participated
in this study. During a normal week of training, session-RPE and HR data were recorded in 96 individual sessions. HR data were analysed using Edwards-TL method. Correlation analysis was used to evaluate the convergent validity between the session-RPE and Edwards-TL methods for assessing ITL
in a variety of training modes (contemporary, ballet, and rehearsal). RESULTS: The overall correlation between individual session-RPE and Edwards-TL was r=0.72, p<0.0001, suggesting there was a statistically significantly strong positive relationship between session-RPE and Edwards-TL.
This trend was observed across all the training modes: rehearsal sessions (r=0.74, p=0.001), contemporary (r=0.60, p=0.001), and ballet (r=0.46, p=0.018) sessions. CONCLUSIONS: This study shows that session-RPE can be considered as a valid method to assess ITL for vocational dance students,
and that notably there is some variation between session-RPE and HR-based TL in different dance activities.

Authors: Woldendorp Kees H , Ploos van Amstel Elise , Boschma Hans , Boonstra Anne M , Arendzen Hans J , Reneman Michiel F
Published: March 2019

AIMS: The objective of this study was to determine the content validity of an assessment instrument for embouchure (the “CODE of Embouchure”) which covers the main aspects of the construct of embouchure in brass players. METHODS: The study design followed the Delphi technique.
A select panel of 35 international experts gave their opinion via a three-round digital Delphi survey as to whether the instrument as a whole, and its items, adequately measure the construct of embouchure. Criteria for consensus and whether items should go through to the next Delphi round
were pre-determined. Data were independently analyzed by two researchers. The CREDES guidelines were used for conducting and reporting of the study. RESULTS: Consensus was reached over 64% and 73% of the closed questions in the first and third rounds, respectively. A second round was necessary
to resolve intra- and inter-expert contradicting information. Finally, 5 items were added to the instrument, 3 items were removed, and 23 items were adjusted. Consensus was reached in 63 items (98%). The final multi-item assessment instrument consists of 4 domains and 64 items. CONCLUSIONS:
Content validity of most aspects of the “CODE of embouchure” instrument was established.
Exploring Professional Circus Artists’ Experience of Performance-Related Injury and Management: A Qualitative Study
Authors: Cayrol Timothée , Godfrey Emma , Draper-Rodi Jerry , Bearne Lindsay
Published: March 2019

AIMS: Circus is a physically demanding profession, but injury and help-seeking rates tend to be low. This qualitative interview study explored the perceptions and beliefs about injury and help-seeking of circus artists. METHODS: Ten professional circus artists (5 males, 5 females; mean
age 33 yrs, range 27–42) were enrolled. Individual, semi-structured interviews were conducted until data saturation of themes was reached. Data were analysed thematically. FINDINGS: Four themes were identified: 1) the injured artist; 2) professionalism; 3) circus life; and 4) artists’
experience of healthcare. Most participants described the circus as central to their lives, and injuries had wide-ranging psychosocial consequences. Injury adversely affected participants’ mood and threatened their identity. Situational and personal factors (e.g., the belief that pain
was normal) pushed participants to use adaptive strategies to perform when injured. Continuous touring and financial constraints affected help-seeking. Easy access to healthcare was rare and participants often self-managed injuries. Experiences of healthcare varied, and participants desired
flexible and accessible approaches to prevention and injury management. A modified version of the integrated model of psychological response to injury and rehabilitation process and the concept of identity provided a framework to understand participants. CONCLUSION: Injuries had extensive
negative consequences. Work schedules, financial factors, employer support, the artist’s perception of the importance of the show, and the relationship between circus and identity influenced injury management and help-seeking. Injury prevention and management strategies could be optimised
by developing centres of expertise, online resources, and better regulations of the profession.
Career Transitions for the Young Dancer: Considering Psychological Implications, Challenges with Athletic Identity, and Need for Available Resources
Authors: Griffin Kelsey L , Gearhart Marina G , Sugimoto Dai , Geminiani Ellen T , Stracciolini Andrea
Published: March 2019

AIMS: Young dancers are likely to revolve their entire identity around dance, and there is the potential risk for disruption to their identity and psychological upset upon change of status or loss of dance following high school. The objective of our study was to systematically review
the current literature examining psychological implications, athletic identity, and career transitions for young dancers. METHODS: A systematic review was performed covering the last 30 years of dance-related literature (1987–2017) through PubMed and EBSCOhost. To be included, the following
criteria had to be met: 1) dancers’ ages were between 14–22 years, 2) dancers’ training experience was documented and its duration was at least 5 years, and 3) information regarding career transition including available resources, athletic identity, or psychological impact
was stated. All statements, documentation, and information related to dancer career transition and choice, including psychological impact, athletic identity, and available resources, were extracted. Quality assessment and level of evidence plans were set a priori. RESULTS: Four publications
were found as a result of the systematic review; however, no study met all three of our inclusion criteria. CONCLUSIONS: No formal research exists that focuses on career transition for young dancers. More studies are needed that focus on the psychological and physical implications of career
decisions for dancers in order to guide healthy decisions when transitioning out of high school into a career path.

Authors: Gorwa Joanna , Zieliński Jacek , Wolański Wojciech , Michnik Robert , Larysz Dawid , Dworak Lechosław B , Kusy Krzysztof
Published: March 2019

AIMS: To compare the differences in bone mineral density (BMD) at loaded and non-loaded skeletal sites in professional ballet dancers. We hypothesized that in both male and female elite ballet dancers, a significant difference in BMD will be observed between impact and non-impact sites.
METHODS: 44 elite ballet dancers, 22 men (age 26.4±5.9 yrs) and 22 women (age 24.9±5.3 yrs), were examined. BMD measurements were performed using dual-energy x-ray absorptiometry at three skeletal sites—forearm (FA), lumbar spine (LS), and femoral neck (FN)—and analyzed
using t-tests, ANOVA, and linear regression models. Information about career duration, training volume, health habits, and menstrual disorders (women) was collected. RESULTS: Z-scores for LS and FN were significantly higher in men than in women. However, Z-scores for FA were similar in men
and women and fell below the expected range for age (<–2.0), and they were significantly lower than those for LS and FN. With longer career duration, a trend was observed towards lower Z-scores for FN in men and towards higher Z-scores for FA in women. CONCLUSION: In ballet dancers,
FA mineralization is extremely low compared to loaded skeletal sites. Male dancers may have lowered forearm BMD despite the absence of risk factors present in female dancers (menstrual disorders). Professional ballet dancers may be at risk of local osteopenia due to the “local non-impact”
characteristics of ballet dance, and use of the 33% distal radius region for the accurate assessment of bone mineral status should be investigated further in this population.
Tongue Position Variability During Sustained Notes in Healthy vs Dystonic Horn Players Using Real-Time MRI
Authors: Iltis Peter W , Frahm Jens , Altenmüller Eckart , Voit Dirk , Joseph Arun , Kozakowski Kevin
Published: March 2019

OBJECTIVE: Embouchure dystonia (EmD) is a variant of focal task-specific dystonia in musicians characterized by the loss of control in facial and oral muscles while controlling airflow into the mouthpiece of a wind or brass instrument. We compared tongue position variability (TPV) during
sustained notes between healthy, elite horn players and horn players affected by EmD. METHODS: Real-time MRI films at 33.3 ms resolution were obtained from 8 healthy elite and 5 EmD horn players as they performed on a non-ferromagnetic horn at each of three different dynamic levels: pianissimo,
mezzo forte, and fortissimo. Nine profile lines (3 from anterior, 3 from middle, and 3 from posterior oral cavity regions) were overlaid on each image using a customized MATLAB toolkit, and the variability of the dorsal tongue edge position was examined at each dynamic from temporal intensity
profiles produced by MATLAB. RESULTS: Despite trends for more pronounced TPV (larger standard deviations) in the elite musicians (p=0.062), 2-way repeated measures ANOVA revealed no significant differences between groups. However, dynamic level significantly influenced TPV for all subjects,
combined (p=0.048) and different regions of the oral cavity showed differing TPV (p<0.001). When only the most active region (anterior oral cavity) was included in the model, differences between groups reached statistical significance (elite > EmD, p<0.048), particularly at the fortissimo
dynamic. We postulate that these differences may be due, in part, to a greater degree of generalized orofacial muscle tension in the EmD subjects that includes the tongue.
Current Approaches for Management of Music Performance Anxiety: An Introductory Overview
Authors: Zhukov Katie
Published: March 2019

Music performance anxiety (MPA) is a complex area with many individual factors contributing to the level of anxiety experienced by musicians during live performances. This paper provides an overview of research literature on performance anxiety, intended for music teachers, students,
and professional musicians, to highlight strategies that have been suggested to manage the accompanying physical and cognitive symptoms. Treatment of MPA includes mindfulness-based approaches, physiological/physically-based therapies, cognitive/behavioural therapies, prescribed medication,
music therapy, and psychotherapy. The most popular approaches for managing the physical symptoms are relaxation techniques, in particular, deep breathing exercises, yoga, and meditation. Other strategies include Alexander technique, bio- and neuro-feedback, healthy lifestyle, and prescription
drugs. Self-handicapping and perfectionism are some of the examples of negative behaviours in musicians. Management of cognitive symptoms of MPA includes cognitive restructuring, realistic goal-setting, systematic desensitisation, music therapy, and/or psychotherapy. Combining behavioural
techniques with cognitive therapy strategies appears to be the most promising approach among interventions aimed at reducing MPA and improving the quality of music performance. Cautious interpretation of the efficacy of interventions is needed due to methodological weaknesses of some research,
and this overview of current approaches is intended to facilitate understanding for those less familiar with this topic.
Use of a Shoulder Rest for Playing the Violin Revisited: An Analysis of the Effect of Shoulder Rest Height on Muscle Activity, Violin Fixation Force, and Player Comfort
Authors: Kok Laura M , Schrijvers Jim , Fiocco Marta , van Royen Barend , Harlaar Jaap
Published: March 2019

AIMS: For violinists, the shoulder rest is an ergonomic adaptation to reduce musculoskeletal load. In this study, we aimed to evaluate how the height of the shoulder rest affects the violin fixation force and electromyographic (EMG) activity of the superficial neck and shoulder muscles.
METHODS: In professional violinists, four different shoulder rest heights during five playing conditions were evaluated. Outcome variables included the jaw-shoulder violin fixation force and bilateral surface EMG of the upper trapezius (mTP), sternocleidomastoid (mSCM), and left anterior part
of the left deltoid muscle (mDTA). Playing comfort was subjectively rated on a visual analogue scale (VAS). Linear regression models were estimated to investigate the influence of the shoulder rest height on muscle activity and violin fixation force as well as the muscle activity of the five
evaluated muscles on violin fixation force. RESULTS: 20 professional violinists (4 males, 16 females, mean age 29.4 yrs) participated in this study. The shoulder rest condition had a significant effect on playing comfort (p<0.001), with higher shoulder rest conditions associated with decreased
subjective playing comfort. The mean violin fixation force for each shoulder rest condition ranged between 2.92 and 3.39 N; higher shoulder rests were related to a higher violin fixation force (p<0.001). CONCLUSION: In this study, violin fixation force and muscle activity of the left mDTA
increased while playing with an increasing height of the shoulder rest. As the shoulder rest influences muscle activity patterns and violin fixation force, adjustment of the shoulder rest and positioning of the violin need to be carefully optimized.

The research attempts to explain Portal Union Catalog Server (UCS) based on Senayan Library Management Systems (SLiMS) in South Sulawesi, Indonesia. Portal UCS becomes the media of technological information in developing cooperation among libraries in searching of the collection in South Sulawesi, Indonesia. This research principally aims to know the implementation of that portal, the obstacles it deals with, and the hope of SLiMS Community on Portal UCS Sulsellib. This research is basically included as a descriptive research using a qualitative approach. As regards to informants as the data sources of research, they are mainly some superintendents and users of Portal UCS Sulsellib. Some research shows that the implementation of Portal UCS Sulsellib can be very helpful for library users in accessing information of collection in various libraries in South Sulawesi because it is only through one door of the portal web of UCS Sulsellib. SLiMS community uses the technic of Waterfall model adapted from System Development Life Cycle (SDLC). The stages of applying this portal are based on waterfall model that is planning, analysis, display design, promotion, implementation, and maintenance. The hope is that this research can extensively upgrade the performance of Portal UCS Sulsellib so that it can be very helpful to explore a collection of information to be more effective and efficient. Besides, it will be used as references to renew the union catalog system.

Background：To compare the clinical performance of bifocal and trifocal intraocular lenses (IOLs) in cataract surgery, a meta-analysis on randomized controlled trials was conducted.

Methods: A comprehensive literature retrieval of PubMed, Science Direct and EMBASE was performed in this systematic review. Clinical outcomes included visual acuity (VA), contrast sensitivity (CS), spectacle independence, postoperative refraction and surgical satisfaction.

Results: There were 8 RCTs included in this study. The difference of uncorrected near VA (UNVA) between the bifocal IOLs and trifocal IOLs had no significance [MD=0.02, 95%CI: (-0.03,0.06)]. There was no significant difference in the distant-corrected near VA (DCNVA) with MD of 0.04 [95%CI (-0.02, 0.10)]. Compared with trifocal group, the uncorrected intermediate visual acuity (UIVA) [MD=0.09,95%CI:(0.01,0.17)] was significantly worse in the bifocal group. No difference was found in distance-corrected intermediate VA(DCIVA) [MD= 0.09, 95%CI: (-0.04, 0.23)] between two groups. Analysis on AT LISA subgroup indicated the bifocal group had worse intermediate VA than trifocal group (AT LISA tri 839M) [MD= 0.18, 95%CI: (0.12, 0.24) for UIVA and MD= 0.19, 95%CI: (0.13, 0.25) for DCIVA]. However, there was no statistically significant difference between the two groups in the uncorrected distance VA(UDVA) and corrected distance visual acuity (CDVA) [MD=0.01, 95%CI: (-0.01,0.04) for UDVA; MD=0.00, 95%CI: (-0.01,0.01) for CDVA].
The postoperative refraction of bifocal group was similar to that of trifocal group [MD=-0.08, 95% CI: (-0.19, 0.03) for spherical equivalent; MD=-0.09, 95%CI: (-0.21, 0.03) for cylinder; MD=-0.09, 95% CI: (-0.27, 0.08) for sphere]. No difference was found for spectacle independence, posterior capsular opacification (PCO) incidence and patient satisfaction between bifocal IOLs and trifocal IOLs. [RR=0.89, 95% CI: (0.71, 1.12) for spectacle independence; RR=1.81, 95% CI: (0.50, 6.54) for PCO incidence; RR=0.98, 5% CI: (0.86, 1.12) for patient satisfaction].

Conclusion: Patients receiving trifocal IOLs, especially AT LISA tri 839M, have a better intermediate VA than those receiving bifocal IOLs. Near and distance visual performance, spectacle independence, postoperative refraction and surgical satisfaction of bifocal IOLs were similar to those of trifocal IOLs.

Background: Randomised controlled trials (RCTs) are widely used for establishing evidence of the effectiveness of interventions, yet public health interventions are often complex, posing specific challenges for RCTs. While there is increasing recognition that qualitative methods can and should be integrated into RCTs, few frameworks and practical guidance highlight which qualitative methods should be integrated and for what purposes. As a result, qualitative methods are often poorly or haphazardly integrated into existing trials, and researchers rely heavily on interviews and focus group discussions. To improve current practice, we propose a framework for innovative qualitative research methods that can help address the challenges of RCTs for complex public health interventions.

Methods: We used a stepped approach to develop a practical framework for researchers. This included: (1) a systematic review of the innovative qualitative methods mentioned in the health literature; (2) in-depth interviews with 23 academics from different methodological backgrounds working on RCTs of public health interventions in 11 different countries; and (3) a framework development and group consensus-building process.

Results: The findings are presented according to the CONSORT Statement categories for ease of use. We identify the main challenges of RCTs for public health interventions alongside each of the CONSORT categories and potential innovative qualitative methods that overcome each challenge are listed as part of a Framework for the Integration of Innovative Qualitative Methods into RCTs of Complex Health Interventions. Innovative qualitative methods described in the interviews include: rapid ethnographic appraisals, document analysis, diary methods, interactive voice responses and SMS, community mapping, spiral walks, pair interviews and visual participatory analysis.

Conclusions: The findings of this study point to the usefulness of observational and participatory methods for trials of complex public health interventions, offering a novel contribution to the broader literature about the need for mixed methods approaches. Integrating a diverse toolkit of qualitative methods can enable appropriate adjustments to the intervention and/ or process of data collection during RCTs, which in turn can create more sustainable and effective interventions. However, such integration will require a cultural shift towards the adoption of method-neutral research approaches, transdisciplinary collaborations, and publishing regimes.

Background: Inspiratory muscle training(IMT) has brought great benefits to improving physical performance in healthy individuals. However, there is no consensus regarding the best training load as in most cases the maximum inspiratory pressure(MIP) has been used, whereby 60% of MIP is the most used. Therefore, the prescription of an IMT protocol that takes into account respiratory muscle strength and endurance may bring additional benefits to the commonly used protocols as respiratory muscles differ from other muscles because of their greater muscular resistance. Thus, IMT using inspiratory critical pressure(PThC) appears as an alternative since the calculation of PThC considers these characteristics. Therefore, the aim of this study is to propose a new IMT protocol to determine the best training load for recreational cyclists.
Methods: Thirty recreational cyclists(between 20-40 years) will be randomized to the SHAM Group(SG), the PThC Group(PCG) and the 60% of MIP Group(60G), taking into account age and aerobic functional capacity. All participants will undergo the following evaluations: pulmonary function test(PFT), respiratory muscle strength test(RMS), cardiopulmonary test(CPET), incremental respiratory muscle endurance test(iRME) [maximum sustained respiratory pressure for 1 minute(PThMAX)] and constant load test(CLT) (95%, 100% and 105% of PThMÁX) using a linear load inspiratory resistor(PowerBreathe K5). The PThC will be calculated from the inspiratory muscle endurance time(TLIM) and inspiratory loads of each CLT. The IMT will last 11 weeks(3 times/week and 1 hour/session). The session will consist of 5-minute warm-ups(50% of the training load) and 3 sets of 15-minute breaths (100% of the training load), with a 1 minute interval between them. RMS, iRME, CLT and CPET will be performed before, at week 3 and 7(to adjust the training load) and after training. PFT will be performed before and after training. The data will be analyzed by specific statistical tests (parametric or non-parametric) according to the data distribution and their respective variances. The p <0.05 will be established.
Conclusions: It is expected that the results of this study will enable the training performed with PThC to be used by health professionals as a new tool to evaluate and prescribe IMT.

Background: Ultrasound-guidance might decrease the incidence of local anesthetics systemic toxicity(LAST) for many peripheral nerve blocks compared with nerve stimulator-guidance. However, it remained uncertain whether ultrasound-guidance would be superior to the nerve stimulator-guidance for deep nerve block in the lower extremity. This study was designed to investigate that whether ultrasound-guided deep nerve block would decrease the incidence of LAST comparing with those with nerve stimulator-guidance, and to find out associated risk factors for LAST.
Methods: Three hundred patients for elective lower limb surgery and desiring lumbar plexus blocks(LPBs) and sciatic nerve blocks(SNBs) were enrolled in this study. Patients were randomly assigned to receive LPBs and SNBs with ultrasound-guidance (Group U), nerve stimulator-guidance (Group N) or dual-guidance (Group M). The primary outcome was the incidence of the LAST. The secondary outcomes were the number of needle redirection, motor and sensory block onset and restoration time in the nerve distributions, and associated risk factors.
Results: There were 18 patients occurring with LAST, including 12 in group U, 4 in group N and 2 in group M. For multiple comparisons among the three groups, we found that the incidence of LAST in group U(12%) was significantly higher than that in group N(4%)(P=0.037) and group M(2%)(P=0.006). The OR of LAST with hepatitis B （HBV） infection and female gender were 3.352(95% CI,1.233-9.108, P=0.013 ) and 9.488(95% CI,2.142-42.093, P=0.0004), respectively.
Conclusions: Ultrasound-guidance, HBV infection and female gender were risk factors for LAST in LPBs and SNBs. For patients with HBV infection or female gender undergoing LPBs and SNBs, we recommended that combined ultrasound and nerve stimulator-guidance should be used to improve the safety.
Trial registration: This study was approved by the Ethical Committee from the first affiliated hospital of Army Medical University. The protocol was registered prospectively with Chinese Clinical Trial Registry (ChiCTR-IOR-16008099) on March 15th，2016.

Background: Developing objective and repeatable indicators to evaluate the efficacy of PVRL treatment is important. The quantification of vitreous cells is a traditional criterion; however slight changes are difficult to ascertain. Spectral domain optical coherence tomography (SD-OCT) is objective, repeatable, and easily explained. The purpose of this study is to provide a longitudinal observation of OCT in PVRL treated with intravitreal injections of methotrexate (MTX) and to evaluate the utility of OCT in monitoringresponsiveness of PVRL to treatment. Methods: The medical records of patients with biopsy-positive PVRL attending our hospital between January 2016 and September 2017 who received intravitreal injections of MTX were included in this study. Pre- and posttreatment OCT images were reviewed independently by two researchers. Results: Of the 24 cases reviewed, 10 patients (18 eyes) were included. SD-OCT abnormalities at the initial visit included hyperreflective foci in the posterior vitreous (18/18), hyperreflective dots in the RPE (12/18), PEDs (detachment of retinal pigment epithelium) (9/18), hyperreflective band above the RPE (3/18), hyperreflectivity in the full thickness of the retina (8/18), and subretinal fluid (4/18). At one month after treatment, the subretinal fluid in cases with RD was absorbed, and subretinal fibrosis appeared. Other lesions were significantly reduced. At two months after treatment, the hyperreflective dots in the RPE, PEDs and subretinal fluid disappeared in 2 eyes, hyperreflectivity in the full thickness of the retina disappeared in 1 eye, and other abnormalities further improved. Additionally, retinal fibrosis was observed in 3 eyes. At nine months after treatment, all abnormalities observed at the first visit vanished. At the last visit, OCT showed subretinal fibrosis and in 3 eyes (16.7%), the disruption of outer retina in 9 eyes (50%) and thinning of the whole layer in 4 eyes (22.2%).Conclusions: Our observations reveal that characteristic OCT features in PVRL patients can reduce gradually and finally vanish with therapy. We propose that SD-OCT may be employed to monitor the responsiveness of PVRL to treatment, which may influence decision making in the management of this disease.

Published: March 2019

Background: Trichilemmal carcinoma (TLC) is a rare malignant adnexal tumor predominantly affecting the scalp, eyelids, neck and face of the elderly. Here, we firstly report a rare case of corneal perforation caused by TLC grown in eyelid margin. Case presentation: A 68-year-old female presented with two months history of unprovoked redness, pain and blurred vision in the left eye. On slit-lamp examination, a 1×2mm aseptic corneal perforation embedded by iris prolapsed was noted. After excluding other causes through examinations and case history inquiry, we speculated that the severe MGD and subsequent BKC might be the cause. In order to prevent the ulcer enlargement and intraocular infection, the patient was treated with penetrating keratoplasty immediately. However, a terrible phenomenon has aroused our concern that several small nodules gradually developed on the eyelid margin, accompanied with bleeding, burst and madarosis postoperatiely. The biopsy revealed the eyelid was involved by TLC and then the lesionectomy was performed immediately. There was no evidence of local recurrence and metastasis during 1 year follow-up.
Conclusions: The involvement of eyelid margin by TLC, and subsequent BKC and corneal perforation were very rare and it has not been reported yet. The concomitant BKC can be gradually healed after rectifying eyelid margin by total excision of TLC. It is very important to offer careful follow-up to all patients.

Background Hemoglobin measurement is important for transfusion decision-making. Pulse CO-Oximetry provides real-time continuous hemoglobin (SpHb) monitoring. The triage role of SpHb trends based on hemoglobin measurements was investigated. Methods In this diagnostic randomized controlled trial, 69 patients undergoing spine or cytoreductive surgery were randomly enrolled into SpHb-monitoring and standard-care groups. Diagnostic blood samples were drawn for CO-oximetry Hb (CoOxHb) when the SpHb decreased by 1 g/dl or at the clinician’s discretion in the standard-care group. The positive predictive value (PPV) was defined as the ability to detect a decrease in CoOxHb > 1 g/dl or a CoOxHb < 10 g/dl; the PPVs were compared using Fisher’s exact test. The SpHb and trend accuracies were calculated. The transfusion units and postoperative hemoglobin levels were compared. Results The PPV of a decrease in CoOxHb > 1 g/dl was 93.3% in the SpHb group vs 54.5% without SpHb monitoring (p = 0.002). The PPV of CoOxHb < 10 g/dl was 86.7% vs. 50.0% for these groups (p = 0.015). The CoOxHb was never < 7 g/dl with SpHb monitoring. Sixty SpHb–CoOxHb data pairs and 28 delta pairs (ΔSpHb-ΔCoOxHb) were collected. The bias, precision and limits of agreement were -0.29, 1.03 and -2.30 to 1.72 g/dl, respectively. When ΔSpHb and ΔCoOxHb were > 1 g/dl, the concordance rate for changes in hemoglobin reached 100%. The delta pairs revealed a positive correlation [ΔSpHb = 0.49 * ΔCoOxHb - 0.13; r = 0.69, 95% confidence interval (0.53, 0.82)]. No significant differences were found in the transfusion volume or postoperative anemia state. Conclusions The SpHb trend tracked changes in hemoglobin satisfactorily during surgery and more accurately estimated the appropriate timing for invasive hemoglobin measurements than the clinicians.

A 28-year-old female patient (right eye: -3.75DS, left eye: -4.00DS) underwent bilateral small incision lenticule extraction. One week after small incision lenticule extraction, her left eye uncorrected distance visual acuity (UDVA) did not reach her preoperative best corrected distance visual acu¬ity (BCDVA) as expected. Examination confirmed that corneal stromal lens fragments remained in the left eye. The lens fragments were removed with a second surgery, and the patient's vision was restored to her preoperative BCDVA. The results of this case yield the following suggestions: ① The lens separation method must be gentle and performed in the same plane. ② It is necessary to confirm the integrity of the lens after the lens is removed.
