Published: September 2019

Recently, the Gravesʼ Recurrent Events After Therapy score (GREAT) was proposed as a useful tool to predict relapse before starting antithyroid drugs (ATD) in patients with Gravesʼ disease (GD). Therefore, we intended to assess the validity of the GREAT score in Turkish patients with GD, including patients who experienced a poorly controlled disease (multiple episodes of hyperthyroidism followed by euthyroidism or rarely hypothyroidism) during ATD dose titration. This is a retrospective multicenter study including 517 patients with the first episode of GD who were treated for at least 12 months. The patients were classified as relapse+poorly controlled disease (non-remission) and remission groups. During a median follow-up time of 35 months (12–144 months), 191 (37%) patients experienced a relapse, 136 (26.3%) a poorly controlled disease, and 190 (36.7%) remained in remission. Patients with non-remission disease tended to have significantly higher serum levels of TRAb, fT4, and fT3, and have larger goiter sizes on palpation at baseline, as compared with the remission group. Non-remission disease occurred in 12, 35, and, 53% of the patients falling into GREAT class I, II, and III, respectively (hazard ratio 2.56, 95% CI 2.02–3.51, p=0.012, and hazard ratio 3.54, 95% CI 2.12–5.91, p<0.001, for GREAT class II and III against class I, respectively). According to our study, the GREAT score is a useful tool to predict the risk of relapse as well as the occurrence of poorly controlled disease before starting treatment with ATDs.
Go with the (Lymph) Flow?
Authors: Mortimer Peter
Published: September 2019

My inspiration for a career in lymphatics came from two sources: the first was a visit to the Foeldi clinic and the second was a visit to Professor Fredi Bollinger’s angiology lab in Zurich. These back to back visits in 1984 gave me insight into the best practice in lymphoedema treatment at the time as well as state of the art research techniques. On my return, I unashamedly introduced the Foeldi principles of lymphoedema treatment to the UK. I also set about setting up Fluorescence microlymphangiography in my new lab. Also present during my visit to Zurich was Hugo Partsch who, as a fellow dermatologist, has been very influential ever since as a role model, mentor and friend.

The idiom ‘go with the flow’ means go with the prevailing attitude or do what the majority are doing even if you disagree. There is an implication one does not really believe it is necessarily the right thing to do but it is the easiest thing to do. There is a tendency currently with interstitial fluid dynamics to ‘go with the flow’ despite overwhelming scientific evidence that the accepted direction of flow is actually incorrect. As a result, the lymphatic system has been underestimated in its importance for the understanding and treatment of peripheral oedema.
Ex Vivo Comparison of the Accuracy of a Clamped with a Hand-Held Drill Guide for Drilling Distal Third Metacarpals and Metatarsals in Equids
Authors: James Oliver A. , Elce Yvonne , Cillán-Garcia Eugenio , Reardon Richard J.M.
Published: September 2019

Objectives The aim of this study was to determine whether a clamped drill guide can be used effectively to drill across equine distal third metacarpals and metatarsals and to compare accuracy and speed of a drilling with a hand-held drill guide.

Study Design Eighty equine cadaver limbs were divided between four surgeons with varying experience. The limbs were randomly allocated to clamped or hand-held drill guides and placed in a stand in an upright/standing position on a metal table. Drilling times from cis- to trans cortices were measured. Post-drilling computed tomography images were used to assess drilling deviations in the dorsopalmar and proximodistal directions.

Results Mean proximodistal deviation of the drill hole was distad for both guides and significantly (p = 0.01) less for the clamped drill guide +0.35° (range: –5.42°, +6.61°, standard deviation [SD] ± 3.18°) than the hand-held drill guide +2.05° (range: –5.24°, +9.81°, SD ± 3.69°). Mean dorsopalmar/plantar deviation was non-significantly (p = 0.17) less for the clamped drill guide −0.27° (range: −9.72°, +6.58°, SD ± 3.57°) than the hand-held drill guide +0.60° (range: −9.74°, + 12.33°, SD ± 4.51°). Mean time taken to drill from cis to trans cortex was significantly (p < 0.001) shorter with the clamped drill guide (41.2s) than the hand-held guide (56.6s).

Conclusion The clamped drill guide could be used successfully on the equine distal third metacarpals and metatarsals and resulted in some improved accuracy and reduced drilling time compared with the hand-held guide. The use of the clamped drill guide in vivo could be supported. This may be of benefit for certain fracture repairs in equids.

Authors: Swaminathan Gowri , Ramalingam Ravi , Kombupalayam Kumarappa Gounder Ramalingam
Published: September 2019

Objective The aim of this study was to compare the effectiveness of intratympanic (IT) steroid therapy and combined intravenous-cum-intratympanic (IVIT) steroid therapy in the management of sudden sensorineural hearing loss (SSNHL).

Study Design This was a nonrandomized clinical trial.

Setting Tertiary referral center.

Patients Forty-four patients, who presented to the outpatient department or the emergency room and those who fulfilled the inclusion criteria, were enrolled in this study. The patients were put into two groups: Group IT—that received intratympanic steroid therapy alone and Group IVIT—that received intratympanic as well as intravenous steroid therapies.

Intervention Therapeutic—in the form of IVIT steroid therapy.

Main Outcome Measure Impact of the steroid therapy in patients with SSNHL was measured objectively with the help of pure tone audiometry (PTA). The improvement in hearing was assessed in terms of decibels gained after the intervention in both the groups.

Results The mean improvement in PTA after 3 months in Group IT was 19.78 (±18.918) dB, whereas the mean improvement after 3 months in Group IVIT was 22.29 (±16.147) dB, statistically showing no significant difference between the groups.

Conclusion The authors recommend the use of IT steroid therapy alone in the management of SSNHL.
The Differing Effect of Gender and Clinical Specialty on Physicians' Intention to Use Electronic Medical Record
Authors: Hwang Hsin-Ginn , Dutta Bireswar , Chang Hui-chuan
Published: September 2019

Background The use of electronic medical record (EMR) is anticipated to bring benefits for patients, physicians, and organizations. But limited physicians' acceptance of EMR presents a serious threat to its effective implementation.

Objectives The current study incorporates technology acceptance model (TAM) with two antecedents, gender, and clinical specialty and one context-specific factor, financial incentives, to identify the factors that influence physicians' intention to use EMR in Taiwan.

Methods The survey methodology was used to collect data from the physicians, working in the regional hospital that had implemented EMR system. A total of 119 out of 213 questionnaires returned in a response rate of 56%. But four responses were considered ineffective due to missing values. The structural equation modeling (SEM) technique was employed to analyze the research framework.

Results The partial least squares (PLS) regression indicated that three factors perceived usefulness, financial incentives, and attitude toward using EMR significantly affect physicians' intention. But concerning perceived ease of use (PEOU), an insignificant path coefficient was reported. Additionally, regression analysis showed gender, and clinical specialty positively influenced physicians' intention to use EMR.

Discussion and Conclusions The proposed research framework contributes to the conclusive explanation for interpreting physicians' intention to use EMR. Physicians generally have a higher level of computer literacy. Therefore, the factor of PEOU could not be critical regarding adopting new health information technology (HIT). This study also brings perspectives from the gender, and clinical differences have primarily been missing in the literature of the physicians' intention to use HIT. In doing so, it infers how gender, and clinical specialty, may complement (and in some instances, reinforce) the influence of technological and attitudinal factors of HIT use. Thus, health care providers must take these factors into consideration in the development and validation of the theories regarding the intention to use EMR.
Revision of a Medial UKA to a Kinematic Aligned TKA: Comparison of Operative Complexity, Postoperative Alignment, and Outcome Scores to a Primary TKA

Published: September 2019

Revision of a medial unicompartmental knee arthroplasty (UKA) to a mechanically aligned total knee arthroplasty (MA TKA) is inferior to a primary TKA; however, revision with kinematic alignment (KA) has not been well studied. The present study determined whether patients revised with KA had a higher use of revision components, different postoperative alignment, and different clinical outcome scores from patients with a primary KA TKA. From 2006 to 2017, all patients suitable for a revision of a failed medial UKA to a TKA and a primary TKA were treated with KA. Reasons for the revision performed in ten females and six males at a mean age 67 ± 8 years included progression of osteoarthritis in the lateral hemi-joint (n = 6), aseptic loosening (n = 4), unremitting medial pain without loosening (n = 4), and insert wear (n = 2). Patients with a revision were matched 1:3 with a control cohort treated with a primary KA TKA. Revisions were performed with primary components without augments, stem extensions, or bone grafts. Seven postoperative alignment parameters of the limb and components were comparable to the control cohort (p > 0.05). At a mean follow-up of 5 years (1–10), implant survival was 100%, and the revision/primary group clinical outcome scores were 39/43 points for the Oxford Knee Score (OKS), 2.2/1.0 cm for the Visual Analog Pain Score, and 12/7 points for the Western Ontario and McMaster Universities Osteoarthritis Index score. When compared with primary KA TKA, surgeons that revise a failed medial UKA to a TKA with use of KA can expect similar operative complexity, comparable postoperative alignments, and a mean OKS of 39 points, which is higher than the mean 27 to 30 point range reported for revision of a failed UKA to a TKA with the use of MA.
Impact of Preoperative Functional Status on Quality of Life after Cardiac Surgery
Authors: Joskowiak Dominik , Meusel Daniela , Kamla Christine , Hagl Christian , Juchem Gerd
Published: September 2019

Background With increasing importance, health-related quality of life (HRQoL) has become a crucial outcome measure of cardiac surgery. The aim of this study was to assess the dynamics of HRQoL change within 12 months after surgery and to identify predictors of deterioration in physical and mental health.

Methods The cohort of this prospective study included 164 consecutive patients who underwent elective surgery. HRQoL was assessed on the basis of the Short-Form 36 questionnaire at three different times: upon admission and at 3 and 12 months after surgery. The minimal clinically important difference (MCID) was used to determine whether the surgery resulted in deterioration of HRQoL.

Results In general, physical and mental health status improved within the first year after cardiac surgery. However, after 12 months, 7.9 and 21.2% of patients had clinically significant poorer physical (PCS) and mental component summary (MCS) scores, based on the MCID approach. The results of multivariate analysis identified preoperative health status, age < 70 years, coronary artery bypass grafting, and a previous neurological event as predictors of deterioration in postoperative HRQoL. The greatest risks for deterioration were higher preoperative PCS and MCS scores.

Conclusion Although we were able to demonstrate a general improvement in the HRQoL following cardiac surgery, in one-fifth of patients, there was no recovery of mental health status even after 1 year. As this effect is mainly determined by preoperative functional status, HRQoL should be an integral part of medical consultation, especially in younger patients with a positive perception of quality of life.
Influence of Variation in Sagittal Placement of the Femoral Component after Cruciate-Retaining Total Knee Arthroplasty
Authors: Koh Yong-Gon , Hong Hyoung-Taek , Lee Hwa-Yong , Kim Hyo-Jeong , Kang Kyoung-Tak
Published: September 2019

Prosthetic alignment is an important factor for long-term survival in cruciate-retaining (CR) total knee arthroplasty (TKA). The purpose of this study is to investigate the influence of sagittal placement of the femoral component on tibiofemoral (TF) kinematics and kinetics in CR-TKA. Five sagittal placements of femoral component models with −3, 0, 3, 5, and 7 degrees of flexion are developed. The TF joint kinematics, quadriceps force, patellofemoral contact force, and posterior cruciate ligament force are evaluated using the models under deep knee-bend loading. The kinematics of posterior TF translation is found to occur with the increase in femoral-component flexion. The quadriceps force and patellofemoral contact force decrease with the femoral-component flexion increase. In addition, extension of the femoral component increases with the increase in posterior cruciate ligament force. The flexed femoral component in CR-TKA provides a positive biomechanical effect compared with a neutral position. Slight flexion could be an effective alternative technique to enable positive biomechanical effects with TKA prostheses.
What is the 'appropriate' fuel management regime for the Otway Ranges, Victoria, Australia? Developing a long-term fuel management strategy using the structured decision-making framework
Authors: Gazzard Tim , Walshe Terry , Galvin Peter , Salkin Owen , Baker Michael , Cross Bec , Ashton Peter
Published: September 2019

The Otway Ranges contain many of the highest-wildfire-risk communities in Victoria, Australia. One of the chief risk mitigation measures in the Otway Ranges is planned burning. The location and amount of planned burning that is undertaken need to consider stakeholder perspectives that can be largely divergent, invoking difficult trade-offs for land-management agencies. The structured decision-making framework was utilised to select the most ‘appropriate’ 40-year cross-tenure fuel management strategy for the Otway Ranges. This paper details the approach undertaken to develop an optimised set of multi-objective fuel management strategies, identify suitable monetary and non-monetary objectives and calculate risk-weighted consequences using a range of modelling techniques. To underpin clarity in trade-offs and decision making, we emphasise the use of natural measures of performance for each candidate strategy against each objective, such as lives lost, species decline and economic losses associated with wildfire. This paper also highlights the role of stakeholder engagement throughout the decision-making process. We discuss the results of the formal trade-off process that was completed using an additive multi-objective value model to identify a preferred fuel management strategy for the Otway Ranges. The preferred strategy is currently used by local management agencies to guide operational planning and delivery.

Published: September 2019

A copper (Cu) foam was brazed with Cu-4.0Sn-9.9Ni-7.8P filler foil for joint strength and interface analysis. Brazed 50 pores per inch (PPI) Cu foam yielded a maximum compressive strength of 14.4 MPa with a 127% increment compared to nonbrazed Cu foam. 15 PPI Cu foam produced a maximum shear strength of 2.7 MPa. Scanning electron microscopy showed that the thickness of the brazed seam decreased with increasing the Cu foam's PPI. The formation of the Cu, Cu3P (P: phosphorus) and Ni3P (Ni: nickel) at the Cu/Cu foam interface was validated using energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction. EDX line scanning analysis revealed the diffusion of P and Ni into Cu foam, which took place via capillary force action.

This diagnostic system is a very important tool for the initial KTX operations. It is compact, with an aperture slit replacing the traditional optical lens system. A flexural interference filter is designed to prevent the center wavelength from shifting too much as the increase of angle from vertical incidence. To eliminate the stray light, the interior of the system is covered with the black aluminum foil having a very high absorptivity. Using the

Especially, Tl2ZrTe3 and Tl2HfTe3 can be good candidates for thermoelectric materials, having narrow band gaps of 0.169 eV and 0.21 eV, respectively. All of the compounds are soft and brittle according to the second-order elastic constant calculations. Low Debye temperatures also support the softness. We have obtained the transport properties of the compounds by using rigid band and constant relaxation time approximations in the context of Boltzmann transport theory. The results show that the compounds could be considered for room temperature thermoelectric applications (

On the applicability of adiabatic approximation in multiphonon recombination theory
Authors: Huang Kun
Published: September 2019

A recent paper by C. H. Henry and D. V. Lang claims that the adiabatic approximation breaks down in the neighborhood of the intersection of the adiabatic potential curves for the two electronic states, between which multiphonon transitions occur. It is shown that their claim is not justified; what they consider to be the sign of failure of the adiabatic approximation is no more than an indication of the fact that owing to the uncertainty principle, there is a finite neighborhood around the above mentioned point of intersection, throughout which multi-phonon transitions can occur. Direct calculation of the multi-phonon transition probability on the basis of the adiabatic approximation gives in fact a result identical with the result obtained with their version of the theory. Further discussions contend that in more general situations Henry and Lang’s formulation of the theory will no longer be applicable and a proper adiabatic approximation treatment by first lifting the degeneracy at the intersection point will be necessary.

Published: September 2019

In this short review, we discuss a few recent advances in calculating the nonradiative decay rates for point defects in semiconductors. We briefly review the debates and connections of using different formalisms to calculate the multi-phonon processes. We connect Dr. Huang’s formula with Marcus theory formula in the high temperature limit, and point out that Huang’s formula provide an analytical expression for the phonon induced electron coupling constant in the Marcus theory formula.

Published: September 2019

Tetanus is caused by Clostridium tetani bacteria that infect open wounds. Tetanus infection can cause death if not treated promply. SIR models are constructed to explain the spread of infectious diseases. Tetanus is not an infectious disease, but SIR models still can be used. Infected persons can not transmit the disease through contact. Tetanus infection is affected by the environment and first aid when injured. Lack of environment and awareness in first aid will increase the case of tetanus. Prevention efforts are done by vaccination in children, women of childbearing age, and pregnant women as protection for mother and baby (maternal antibody). The purposes of this research are to formulate SIR model with vaccination and maternal antibody (MSVIR) for tetanus disease and to apply the model in Indonesia. The MSVIR model is a first order linear differential equation system with five dependent variables, there are M, S, V, I, and R, and an independent variable t (time). The parameter’s values were estimated based on data in 2009-2014. The accuracy of this model was measured based on data in 2015-2016 years. The relative error rates on 2015-2016 were -0.0567 and 0.0825. The model is considered good enough. Based on the predictions during 2011-2030, the incidence of tetanus will increase 6.62% by 1.2% average increase per year.

Authors: Andriani Putri , Chamidah Nur
Published: September 2019

Hypertension called as the silent killer, is the number one non-infectious disease that causes death in the world every year. There are 185,857 cases recorded in 2018 in Indonesia. In this study, we model the hypertension risk by considering age, heart rate, hypertension history of family, eating salty foods, and smoking or exposure to cigarette smoke as the influence factors of hypertension risk. A cross-sectional survey was conducted in August 2018 at the Haji Hospital of Surabaya. Logistic regression is used to analyse the influence of various risk factors on hypertension and non-hypertension. In addition, we compare between logit and gompit link functions in logistic regression to build the modelling of hypertension risk factors based on the accuracy of the classification model. By using logit and gompit link functions, we obtain percentage of the classification accuracy are 85.2 % and 81.5 %, respectively. It means that the logit link function is better than the gompit link function for modelling hypertension risk factors. For these link functions, the significant factors that influence hypertension are age and heart rate.
On Edge Irregular Total k-labeling and Total Edge Irregularity Strength of Barbell Graphs
Authors: Aftiana Melli , Indriati Diari
Published: September 2019

Let G be a connected graph with a non empty vertex set V(G) and edge set E(G). An edge irregular total k-labeling of a graph G is a labeling λ : V(G) ⋃ E(G) → {1, 2, …, k}, so that every two different edges have different weights. The weight of edge uv of G is the sum of the labels vertices u and v and label of the edge uv, which is can be written as wt(uv) = λ (u) + λ (uv) + λ(v). The total edge irregularity strength of G, denoted by tes(G) is the minimum positive integer k for which the graph G has an edge irregular total k-labeling. Barbell graph Bn
is obtained by connecting two copies of a complete graph Kn
by a bridge. In this research, we determined the total edge irregularity strength of barbell graph Bn
for n ≥ 3.
Optimal control of a mathematical model for Japanese encephalitis transmission
Authors: Kharismawati Heni , Fatmawati  , Windarto
Published: September 2019

Japanese encephalitis (JE) is a vector-borne disease that causes encephalitis mostly children in Asia and livestock. A mathematical model can be used to predict JE spread in the future. In this paper, we analysed a mathematical model of JE transmission. We also applied several optimal control variables such as vaccination and treatment to the human population, insecticide to mosquito population, and vaccination to pig population. Based on the analysis results, we obtained two equilibriums, namely disease-free equilibrium and endemic equilibrium. The existence and stability of the equilibriums depended on R
0 (basic reproduction ratio). The disease-free equilibrium is locally asymptotically stable if R
0 < 1, while the endemic equilibrium is locally asymptotically stable if R
0 > 1. Furthermore, we determined the existence of the optimal control variables by Pontryagin Maximum Principle. Numerical simulation showed that the control strategies are effective to minimize the number of active JE in human, mosquito and pig population.

Authors: Rahmayanti N A P , Yonani Y S , Mardianto M F F
Published: September 2019

Diarrheal is a disease with the condition of faeces becoming soft or fluid. In general, diarrheal results from food and drinks exposed to viruses, bacteria or parasites. Diarrheal is one of the health problems of people in poor and developing countries. Diarrheal often occurs due to the lack of clean water that pass health requirements. The method used in this research is bivariate negative binomial regression which is a regression method to model a pair of response variables, each of which has a negative binomial distribution and correlates. This study uses 38 secondary data from the East Java Provincial Health Office in 2016 about the number of diarrheal sufferers and the number of certified drink water providers which pass health requirements. The results of this research, there are 4 factors that significantly influence the model of diarrheal sufferers and drink water providers who pass health requirements, that are the percentage of residents with access to proper sanitation, public places that pass health requirements, population literacy rates and food management places tested.

Authors: Suparti  , Santoso R , Prahutama A , Devi A R
Published: September 2019

Regression analysis is a statistical method to determine the relationship between predictor variables and response variables. Regression approach can be done with parametric and nonparametric approaches. The parametric approach is rigorous with assumptions and must fulfillthe assumptions to get a good model.Meanwhile, the nonparametric approach is not rigorous with assumptions because the method is based on an unknown curve shape approach. Nonparametric regression can be done with several approaches including Fourier and Wavelet methods. The Fourier method is a method based on cosine and sine series. It is very suitable for data that has repetitive or periodic patterns. The Fourier series modeling is less efficient because it requires many coefficients to obtain a good model and it is less able to handle data with sharp jumps. Recently, there has been a combination of two methods called hybrid methods that give better results. In this paper, Indonesia’s inflation data modelling is performed by using hybrid-wavelet. First, the data is modeled using Fourier with small K; then the error Fourier model is modeled by using multiscale waveletautoregressive. In this study, the value of Inflation in Indonesia was modeled from January 2007 to August 2017. The response variable was the inflation value, while the predictor variable was time. The Fourier method with K = 100 generated MSE of 0.846216 and R2 of 80.12%. The Fourier-Wavelet hybrid model with K = 1 generated MSE of 0.31 and R2 of 95%. So that in inflation modeling in Indonesia, the Fourier-Wavelet hybrid regression model generated a better model than the wavelet model with fewer parameters than the Fourier method.

Semiparametric approaches using Kernel, Splines and locally-weighted regression smoothing were used to model mortality pattern among the government university employee as alternative to the parametric approaches. The results from those three type of smoothing methods were compared. The final results of the estimates were also compared to the standard model of mortality pattern among the government employee in Indonesia, the TASPEN mortality table, and the population life table from the 2010 Indonesian population census.
Urban agriculture’s bounty: contributions to Phoenix’s sustainability goals
Authors: Uludere Aragon Nazli , Stuhlmacher Michelle , Smith Jordan P , Clinton Nicholas , Georgescu Matei
Published: September 2019

With over half of the world’s population living in cities, there is mounting evidence indicating that investments in urban sustainability can deliver high returns on socioeconomic and environmental fronts. Current scholarship on urban agriculture (UA) reports a wide range of benefits which have been shown to vary with the scale and type of benefit examined. Notably, most city-scale studies do not align benefits of UA with locally meaningful goals. We fill this gap by conducting a city-scale analysis for Phoenix, the fifth largest city in the USA by population, and evaluate these benefits based on their ability to contribute to select desired outcomes specified in Phoenix’s 2050 Sustainability Goals: the elimination of food deserts, provision of green open space, and energy and CO2 emissions savings from buildings. We consider three types of surfaces for UA deployment—undeveloped vacant lots, flat rooftops, and building façades—and find that the existing building stock provides 71% of available UA space in the study area. The estimated total food supply from UA is 183 000 tons per year, providing local produce in all existing food deserts of Phoenix, and meeting 90% of current annual consumption of fresh produce based on national per capita consumption patterns. UA would also add green open space and reduce by 60% the number of block groups underserved by public parks. Rooftop deployment of UA could reduce energy use in buildings and has the potential to displace more than 50 000 tons of CO2 per year. Our work highlights the importance of combining a data-driven framework with local information to address place-based sustainability goals and can be used as a template for city-scale evaluations of UA in alternate settings.

Authors: Kosum K , Bun-art S
Published: September 2019

This study aimed to determine the amount of impurities adhering to sugarcane harvested from sugarcane harvesters. A factorial experimental design was used to study the effect of three factors: sugarcane type, planting and soil type. The experiments showed that the three factors affected the quantity of impurities adhering to the sugarcane. The following types of impurities can be classified as tops at 54%, trash at 32%, and root and soil at 14%. The variance analysis was done at a significant level of 0.05, and it was found that the sugarcane type and the planting technique had an influence on the amount of tops impurities in both terms of the main factors and co-factors. The type of sugarcane was the main factor affecting the amount of trash impurities in terms of main factors; planting and soil type had an influence on the amount of trash impurities in terms of the co-factors.
