Experiencing polyphonic music may enhance memories retention
Authors: Habib Zadeh Shima , Rouhbakhsh Nematollah , Mohammadkhani Ghasem
Published: May 2019

Background and Aim: Early experience, prov­ide opportunity for later associative experiential learning by affecting multisensory systems. This phenomenon may because of the influences which sensory stimuli as sounds would have on non-auditory neural centers rather than just dep-loying hearing system, so the question is wheth­er music as a kind of complex sound source, could help in general cognitive functions such as memory circuits or, conversely, it acts as a distracting factor. This study was investigated the effect of auditory experience with special kind of music, called polyphonic music, on auditory, visual and logical memories function.
Methods: Forty volunteers with normal hear­ing, aged 18 to 40 years, were participated in this experimental study. They were performed with Ray auditory verbal learning test, Kim Karad visual memory test, and Wechsler logical memory subtest in two states: no-music con­dition and music condition with a polyphonic piece as background music. Memory functions in these two conditions, and the effect of gender on performances, were compared between con­ditions.
Results: Polyphonic music significantly inc­reased auditory, visual and logical memory
performance compared with the no-music con­ditions (p < 0.05). No significant difference bet­ween genders was found in memory tasks in both music and no-music conditions (p > 0.05).
Conclusion: It seems that presence of poly­phonic music while people had enough auditory experience about it, impress memory perfor­mance. It is possibly owning to multisensory functions of brain and the effect of auditory experiences on cognitive system.

Background and Aim: The presence of a child with hearing impairment in the family is often problematic and needs psychological interven­tions. The purpose of this study was to inves­tigate the effect of acceptance and commitment therapy (ACT) on the symptoms of anxiety and depression in mothers of hearing-impaired or deaf children.
Methods: This is a quasi-experimental study with pretest-posttest design and with experi­mental and control groups. The study population comprised all mothers of hearing-impaired or deaf children of 2–6 years old in Tabriz City, Iran. Using purposive sampling method, 32 mothers of hearing-impaired or deaf children were selected and then randomly assigned to control and experimental groups (each with 16 subjects). The experimental group was treated with ACT during 8 sessions of 1.5 hours long in two weeks. The study data were collected by the depression anxiety stress scale.
Results: ACT was effective in decreasing anxi­ety and depression symptoms in mothers of hearing-impaired or deaf children (p < 0.05).
Conclusion: Considering the results and effecti­veness of ACT in reducing the symptoms of
anxiety and depression in mothers of hearing-impaired or deaf children, this treatment is rec­ommended in rehabilitation centers for children with hearing problems.

Mutations in the HNF1A gene as a cause of MODY3: a clinical case
Authors: Demidova T. Yu. , Gritskevich E. Yu. , Balutina O. V.
Published: May 2019

Genetic dysfunction of the pancreatic β-cells and/ or factors participating in glucose metabolism can form the bases for monogenic types of diabetes mellitus. Diagnosis of MODY type of diabetes is difficult due to its rare identification in the real clinical practice and to the necessity of molecular genetic testing for the confirmation of specific mutations. Errors in the diagnosis of diabetes mellitus may be misleading for the choice of hypoglycemic treatment, which is the key problem in the management of these patients. In the clinical case described, the diagnosis of MODY3 related to the mutations in the HNF1A transcriptional factor was confirmed during pregnancy of the patient, i.e. more than 15 years had passed from manifestation of the disease in childhood, despite typical clinical symptoms and specific familial history. Optimization of the early diagnosis and management of this patient cohort can be facilitated by accumulation of theoretical knowledge and practical experience, as well as improvement of diagnostic capacities, including higher availability of molecular genetic analysis.
Ann's Story: An Authentic Learning Experience for Online Nursing Students
Authors: Baron Kristy , Rocha Ann , Anderson Pamela
Published: May 2019

Preparing students for a complex and ever-changing health-care environment is a daunting task for nurse educators. One way to accomplish this task is by reducing the gap between what is learned in school and what is practiced upon graduation. Nurse educators are challenged to create online environments that engage students with real-life activities that resemble practice-authentic learning. One authentic learning activity created for an oncology nursing course that resonated with students was Ann's Story. Ann, a nursing professor, was diagnosed with cancer, and her story was used in a course about caring for patients with cancer. Ann's goal of making something good come of her cancer diagnosis was met through student comments reflecting newfound wisdom in sharing thoughts, feelings, and compassion with patients rather than concentrating only on the completion of tasks.

Perceptions of Principals and Teachers on the Level of Organizational Narcissism, High Schools in Sakarya Province Sample
Authors: HAMEDOĞLU Mehmet Ali
Published: May 2019

Both private
and public high schools including general high schools, science and Anatolian
high schools have constituted the universe of this study. The sample, a total
of 299 teaching stuff, were selected those specified high schools’ including 46
managers and 253 teachers of 299 people formed the research sample. The results
of the research showed that socio-economic level and academic achievement
linearly related to organizational narcissism. Because the level of
organizational narcissism of private schools were higher than those of the
public schools and the level of organizational narcissism of Anatolian and
science high schools for which their teachers and students are selected via a
national entrance and placement examination 
were higher than those of general high schools.This research
examining the level of organizational narcissism and its relations to some
variables was completed by the help of data picked from 18 high schools in
Sakarya province. For some
reasons, such as having a perception and questionable appreciation of students
levels and scores in various exams (national or regional) are equivalent to
school achievement, criticizing schools that don’t have resembling scores, and
differences and variances about resources use, private high schools have higher
levels of narcissistic characteristics than state high schools, state high
schools for which teachers and students are selected via a national entrance
and placement examination have higher levels of narcissistic characteristics
than other state schools in which no such an exam is conducted.

Des confusions entre espèces préjudiciables à la gestion durable des essences forestières : l’exemple des acajous d’Afrique (Khaya, Meliaceae)
Authors: Bouka Dipelet Ulrich Gaël , Doumenge Charles , Loumeto Jean Joël , Florence Jacques , Gonmadje Christelle , Mckey Doyle
Published: May 2019

Les espèces du genre Khaya procurent l’un des bois les plus prisés du continent africain. Elles sont commercialisées sous l’appellation « acajou d’Afrique » depuis environ deux siècles. En Afrique continentale, on reconnaît actuellement quatre espèces morphologiquement proches : Khaya anthotheca, K. grandifoliola, K. ivorensis et K. senegalensis. Le nombre de taxons du genre Khaya a varié au cours du temps et la délimitation de ces taxons n’est pas sans avoir des implications sur les stratégies de conservation et de gestion durable des espèces. L’objectif du travail présenté ici est de s’assurer de la délimitation de ces espèces sur la base d’un bilan des connaissances actuelles en taxonomie, génétique, écologie et chimiotaxonomie. Les données disponibles ne permettent pas toujours de séparer sans ambiguïté les quatre acajous d’Afrique continentale. Elles permettent toutefois d’avancer que K. ivorensis, K. grandifoliola et K. senegalensis seraient des espèces à part entière mais dont les limites taxonomiques doivent encore être précisées. Khaya nyasica serait également une espèce qui devrait être séparée de K. anthotheca. Au sein de cette dernière, plusieurs chémotypes ont été identifiés, ce qui suggère que ce taxon pourrait recouvrir un ensemble plus complexe d’au moins deux autres taxons dont le rang spécifique ou sous-spécifique reste à préciser. Des recherches morphométriques, génétiques et écologiques doivent être développées afin de clarifier le statut systématique et l’histoire évolutive de ces divers taxons, en vue de formuler des recommandations appropriées pour la gestion durable des acajous d’Afrique.

The Isometric Quadriceps Contraction Method for Intra-Articular Knee Injection
Authors: Wada Makoto , Fujii Tadashi , Inagaki Yusuke , Nagano Tatsuo , Tanaka Yasuhito
Published: May 2019

The intra-articular injection is the most important technique for treating not only rheumatoid arthritis but also osteoarthritis of the knee. However, 1 problem is that the drug is often inaccurately injected outside of the joint, especially when no effusion is present. According to a previous systematic review by Maricar et al., the use of a superolateral patellar approach without ultrasonography had a higher success rate (87%) than both a medial midpatellar approach (64%) and an anterolateral joint-line approach (70%). For knees with little effusion, we devised a method of intra-articular injection in which the needle is inserted into the suprapatellar pouch while the patient maintains isometric contraction of the quadriceps. This method, which we call the isometric quadriceps contraction (IQC) method, is based on the concept that isometric contraction of the quadriceps induces contraction of the articularis genus muscle complex, thus expanding the volume of the suprapatellar pouch. The major steps of the procedure are (1) patient positioning and knee placement, (2) finding the puncture point, (3) isometric quadriceps contraction, and (4) needle approach to the suprapatellar pouch and injection. We also show the ultrasound evaluation of the suprapatellar pouch expansion under IQC and the accuracy of the IQC method compared with that of the non-activated quadriceps method. The results of this injection method indicate that the suprapatellar pouch is likely to expand during IQC, improving the probability of successful intra-articular injections. We believe that the IQC method is therapeutically effective and achieved a success rate of 93.3% despite the presence of little effusion and no use of ultrasonography.
Estimating the annual risk of infection with Mycobacterium tuberculosis among adolescents in Western Kenya in preparation for TB vaccine trials
Authors: Nduba Videlis , Hoog Anna H. van’t , de Bruijn Annefleur , Mitchell Ellen M.H. , Laserson Kayla , Borgdorff Martien
Published: May 2019

Background: Adolescents are a prime target group for tuberculosis (TB) vaccine trials that include prevention of infection (POI). The BCG vaccine is given at birth and does not prevent TB infection. TB infection, a critical endpoint for POI vaccine trials would need to be documented to estimate sample sizes in target populations.
Methods: Adolescents aged 12-18 years of age were enrolled in an area under continuous demographic surveillance. A tuberculin skin test (TST) survey was conducted as part of a study on TB prevalence and incidence. All adolescents got TSTs at enrolment and returned after 72 hours for reading. A TST of ≥10mm if HIV negative or ≥ 5mm if HIV positive, was considered positive.
Results: Of 5004 adolescents enrolled, 4808 (96%) returned for TST readings. Of these 2327(48.4%) were female, 861 (17.9%) had no BCG scar, and 23 (0.5%) were HIV positive. The baseline prevalence of tuberculous infection was 32% (95% CI 29-35%) with a corresponding ARTI of 2.6% (95% CI 2.2-3.1%). Male gender (OR 1.3, 95%CI 1.2,1.5), having a BCG scar (OR 1.4,95%CI 1.3,1.7) and not being enrolled in school (OR 1.8, 95%CI 1.4,2.3) were independent predictors of a positive tuberculin skin test at baseline.
Conclusion: We conclude that the high TB transmission rates we found in this study, suggest that adolescents in this region may be an appropriate target group for TB vaccine trials including TB vaccine trials aiming to prevent infection.

Authors: Wang Dongmei , Wu Yongming , Ji Zhong , Wang Shengnan , Xu Yunqi , Huang Kaibin , Peng Yu , Zheng Hui , Wang Honghao , Zhang Xiaomei , Pan Suyue
Published: May 2019

Background: Anti-N-methyl-d-aspartate (anti-NMDA) receptor encephalitis is an autoimmune-mediated disease, which is predominant in young female patients with ovarian teratomas. With proper immunotherapy, most of the patients achieve good prognosis. Nevertheless, some patients may be refractory to first and second-line immunotherapy, thus new treatments are required to help these patients.
Case presentation: We present a case of anti-NMDA receptor encephalitis with ovary teratoma. After the prompt removal of the teratoma and strong immunotherapy including intravenous methylprednisolone pulse (IVMP), intravenous immunoglobin (IVIG), plasmapheresis, immunoadsorption, intravenous cyclophosphamide, and rituximab, the patient’s neurologic status did not improve. Bilateral ovariectomy was then conducted and intrathecal injection of methotrexate (MTX) and dexamethasone (DXM) was given. The patient’s neurological symptoms improved dramatically， and she achieved a good prognosis after 23 months.
Conclusions: For refractory cases of anti-NMDA receptor encephalitis, intrathecal injection of MTX and DXM may be beneficial. More research is required to elucidate the mechanisms of intrathecal treatment.

Authors: Chierrito Danielly , Villas-Boas Camila B. , Tonin Fernanda S. , Fernandez-Llimos Fernando , Sanches Andréia C.C. , de Mello João C.P.
Published: May 2019

Background:

Advances in basic and molecular biology have promoted the use of cell
cultures in a wide range of areas, including the evaluation of drug efficacy, safety and toxicity.

Objective:

This article aims to provide a general overview of the methodological parameters of cell
cultures used to investigate therapeutic options for Attention Deficit Hyperactivity Disorder.

Methods:

A systematic search was performed in the electronic databases PubMed, Scopus, and
DOAJ. In vitro experimental studies using cell cultures were included.

Results:

A total of 328 studies were initially identified, with 16 included for qualitative synthesis.
Seven studies used neuronal cells (SH-SY5Y neuroblastoma and PC12 cell line) and nine used nonneuronal
cells. All the studies described the culture conditions, but most studies were inconsistent
with regard to reporting results and raw data. Only one-third of the studies performed cell viability
assays, while a further 30% conducted gene expression analysis. Other additional tests included
electrophysiological evaluation and transporter activity. More than 50% of the studies evaluated the
effects of drugs such as methylphenidate and atomoxetine, while plant extracts were assessed in
four studies and polyunsaturated fatty acids in one.

Conclusion:

We suggested a flowchart to guide the planning and execution of studies, and a checklist
to be completed by authors to allow the standardized reporting of results. This may guide the
elaboration of laboratory protocols and further in vitro studies.
Carbonylation of Aryl Halides in the Presence of Heterogeneous Catalysts
Authors: Urbán Béla , Papp Máté , Skoda-Földes Rita
Published: May 2019

Palladium-catalyzed carbonylation in the presence of organic and organometallic nucleophiles serves as a powerful tool for the conversion of aryl/alkenyl halides or halide equivalents to carbonyl compounds and carboxylic acid derivatives. To circumvent the difficulties in product separation and recovery and reuse of the catalysts, associated with homogeneous reactions, supported counterparts of the homogeneous palladium catalysts were developed. The review intends to summarize the huge development that has been witnessed in recent years in the field of heterogeneous carbonylation. A great plethora of supports, organic modifiers on solid surfaces stabilizing metal particles, transition metal precursors, as well as alternative sources for CO was investigated. In most cases, careful optimization of reaction conditions was carried out. Besides simple model reactions, the synthesis of carbonyl compounds and carboxylic acid derivatives from substrates with different functionalities was performed. In some cases, causes of palladium leaching were clarified with detailed investigations. The advantages of immobilized catalysts were shown by several examples. The possibility of catalystrecycling was proved besides proving that metal contamination of the products could often be kept below the detection limit. At the same time, detailed investigations should be carried out to gain a better insight into the real nature of these processes.
Estimation of the average time to failure of the turning steps according to the operation data
Authors: Belousova M. V. , Bulatov V. V.
Published: May 2019

The purpose of this study is to determine the empirical law of the distribution of developments to the failure of the turning steps installed on passenger cars of locomotive traction. The correct choice of the distribution law for each technical product allows for the current calculation of reliability indicators, predicting them, as well as developing preventive measures for a specific technical product and leveling costs both during production and during operation.The article presents well-founded arguments that the failure time for turning steps is characterized by the Weibull distribution law. For confirmation, a statistical criterion for checking the deviation of the distribution from the normal one was applied.On the basis of carried statistic analysis a histogram of frequencies and a line of the density function of samples of failure time in the data fixation period from 2010 to 2017 were built. Results of applying the 2 agreement criterion in the same software environment revealed that the failure time of the closed turning step comply with the law of Weibull distribution. Authors suggest using the maximum likelihood method to identify Weibull distribution parameters, on the basis of which the value of the point estimate of the mean time to failure is calculated.Based on the research, it is concluded that this type of distribution law and the process of finding its parameters should be introduced into the program and methodology for assessing the operational reliability of the turning steps, when calculating the average time to failure of the steps, and consider the possibility of applying this law for analogous products.In conclusion, calculation of the pointed estimation of the average time to failure of the closed turning step was made on the basis of operational tests for one year in accordance with the adopted distribution law.
Development of the lubricant for side-mounted rail flange lubricators for traction rolling stock
Authors: Glazunov D. V.
Published: May 2019

Specificity of operating conditions of the rolling stock defines a number of requirements for lubricants intended for the wheel-rail tribosystem. Lubricants are used for “wheel — rail” contact, the aggregate state of which varies from liquid to solid. When evaluating the lubrication properties of these materials, a significant number of factors must be taken into account, in particular, influence of the environment, method of application, condition of the rail surface. The paper discusses the main operational requirements for lubricants operating in a wheel-rail tribosystem. Temperature ranges of the lubricants used for the “wheel — rail” contact on the railway network of the Russian Federation are given. As a result of the research, it was determined that none of the materials used for lubrication of the wheel-rail system satisfies the operating temperature conditions of the traction rolling stock.  To solve this problem a lubricant was developed and tested in an industrial environment at the Rostov State University of Railway Transport. Its lubricant composition allows to significantly expand the temperature range of the lubricant. Complex of experimental studies and method of orthogonal central composite plan of the 2nd order established the optimum values of the thickness of the working shell of the 0.846 mm lubricating rod and the 50.411 % percentage of plastic lubricant, allowing to extend the temperature range of lubricant rods and, in particular, completely eliminate the lubricant flow to achieve a temperature of 126.034 °C. Proposed composition of the lubricant was tested on a freight electric locomotive of the VL80T series, equipped with non-power lubricators, under the conditions of the Bataysk — Likhaya section of the North Caucasus Railway. Intensity of wear of the wheel flanges of the traction rolling stock lubricated by the proposed material, compared with the intensity of wear of the wheel flanges without the use of lubrication systems is reduced by 2 times.
Democracy, Islam and Party System in Indonesia: towards a consensus-oriented model?
Authors: Gyene Pal Istvan
Published: May 2019

This paper argues that the impact of “Islam” on the Indonesian political system is worth studying on three different levels: 1. society’s political divisions; 2. the party system 3. parliamentary politics. I contend that there is a specifically Indonesian “consensus-oriented” democracy model involved in the process—which is not, however, without Western predecessors—wherein political Islam and Islamist parties act not as destabilising factors but rather as “Muslim democratic” forces that strengthen democratic consensus in a manner similar to some “Western” Christian democratic parties. This research is based partly on a historical and, implicitly, comparative approach. It builds strongly on the theoretical framework and methodology of Sartori’s classic party system typology, Lijphardt’s “majoritarian” and “consensus-based” democracy model, and the so-called neo-institutionalist debate on the possible advantages and disadvantages of parliamentary and presidential governments.

Authors: Feldman Steven R , Pelletier Corey L , Wilson Kathleen L , Mehta Rina K , Brouillette Matthew A , Smith David , Bonafede Machaon M
Published: May 2019

Aim:
We evaluated treatment patterns and healthcare costs of initiating psoriatic arthritis (PsA) treatment with oral apremilast versus biologics.
Methods:
Claims data identified biologic-naive adults with PsA who initiated either apremilast or a biologic from 2013 to 2016.
Results:
Medication adherence was similar at 12 months (76.9 vs 73.4%; p = 0.175) between apremilast (n = 381) and matched biologic (n = 761) patients. Apremilast users had $12,715 lower total costs per-patient-per-month (p < 0.001), largely due to outpatient pharmacy and medical costs.
Conclusion:
Commercially insured patients with PsA initiating apremilast had adherence similar to those initiating biologics but lower total healthcare costs.
Transgenderism and Transracialism: Ontological Contrasts between Gender and Race
Authors: Guerrero Mc Manus Siobahn
Published: May 2019

A comienzos de 2017 Rebecca Tuvel publicó un texto intitulado In Defense of Transracialism; este texto defendía que las razones que tenemos para aceptar la transgeneridad/transexualidad deberían, llevarnos a aceptar a la transrracialidad como posibilidad dado que tanto la ontología del género como la de la raza compartían dos elementos fundamentales: la autoidentificación y el etiquetamiento por parte de terceros. En el presente trabajo se cuestiona la validez de esta extrapolación al señalar que ésta conduce a análisis metafísicos y políticos que ignoran tanto la historicidad como la materialidad que caracterizan a las diversas categorías así homologadas. De allí que aquí se cuestione críticamente cierta tendencia que ha igualado diversas ontologías sociales, por un lado, mientras que, por otro, se enfatizan otros abordajes metafísicos que no incurren en estas problemáticas.

Therefore photodegradation method is done by using semiconductor and visible light radiation. The semiconductor used is based on copper sulfate hydrate and silver nitrate. The copper sulphate hydrate precursor is made from the processing of copper-cut copper metal waste in the workshop of the Indonesian Institute of Sciences (LIPI) in Bandung. Semiconductor materials also have the ability to inhibit bacterial growth. The optimum results obtained in the photodegradation and antibacterial process are a combination of both copper sulfate hydrate precursor and silver nitrate with the help of irradiation. The ability to inhibit bacterial growth obtained 100% mortality for each bacterium, namely Escherichia coli and Staphylococcus aureus. Photocatalytic activity with 10 ppm semiconductor concentration to degrade methyl red dye 5 ppm, for 23 hours, where the percentage of degradation obtained by irradiation is higher than without irradiation. The effect of pH of the solution on the degradation of methyl red is optimum at pH 12 (base).

Secant Parallels in Azimuthal Projections
Authors: Lapaine М.
Published: May 2019

Map projections are commonly approached as mapping onto developable surfaces; cylindrical projections onto the lateral surface of a cylinder, conic projections onto the lateral surface of a cone, and azimuthal projections onto a plane. If an intermediate developable surface intersects the Earth’s sphere or ellipsoid, the projection is referred to as a secant projection. The intersection of a developable surface and the Earth’s sphere or ellipsoid, e.g. secant parallel is considered a standard parallel. In this paper the definitions of secant and standard parallel in azimuthal projections are given. The first conclusion is that the secant and standard parallels are two distinct notions. The second one is that a standard parallel, if such a parallel exists in an azimuthal projection, is a secant parallel, while the converse statement is not true in general. Furthermore, it is shown that there are azimuthal projections with only one secant parallel that is not standard, with only one standard parallel which is also secant one, with two different secant parallels, and with one standard and one secant parallel.

This article discusses juridical implications about the regulation of state-owned enterprises (BUMD) after the enactment of the Law Number 23 Year 2014 about Regional Government (Regional Government Law 2014) and the application on regulation of BUMD in Jambi Province. Research methode in this study is normative juridical with law approach. Based on the results of the study are known, the enactment of Regional Government Law 2014 has implications for the existence and regulations of existing and future of BUMD, namely in terms of form and naming of BUMD; organ of BUMD; tenure of directors and councils; and intervention of DRPD (Regional People’s Representative Assembly) on BUMD operations. The result of the study also shows that not one regional government in Jambi Province that followed up on the mandate of the article 402 paragraph (1) Regional Government Law 2014 to adjust the regulation of BUMD, and that’s why it is potentially contradicting with Regional Government Law 2014 and central government policy.

Abstrak

Artikel ini membahas implikasi yuridis pengaturan Badan Usaha Milik Daerah (BUMD) pasca berlakunya Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintahan Daerah (UU Pemda 2014) dan penerapannya pada regulasi BUMD di lingkungan Provinsi Jambi. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan. Berdasarkan hasil kajian diketahui, berlakunya UU Pemda 2014 berimplikasi terhadap eksistensi dan regulasi BUMD baik yang telah ada maupun yang akan dibentuk, yaitu dalam hal bentuk hukum dan penamaan BUMD; persyaratan pendirian dan kelayakan usaha BUMD; penyertaan modal daerah dan kepemilikan modal dalam BUMD; organ BUMD; masa jabatan Direksi dan Dewas/Deris; dan campur tangan DPRD dalam operasional BUMD. Hasil penelitian juga menunjukkan belum ada satu pun Pemda di lingkungan Provinsi Jambi yang menindaklanjuti amanat Pasal 402 ayat (1) UU Pemda 2014 untuk menyesuaikan regulasi BUMD, dan dengan demikian potensial bertentangan dengan UU Pemda 2014 dan kebijakan pemerintah pusat.
How Reliable The Measurement of Predictors Should Be: Monte Carlo Study in the Regression Framework
Authors: Santoso Agung
Published: May 2019

Current study investigate the effect of measurement error on the estimation of predictors that are measured either with or without error, type 1 error rates, and power to detect non-null parameters. Author also looked for minimum value of measurement reliability needed for the analysis to provide desired results. Such value used to be based only on subjective judgements without any empirical study to support them. Simulation was conducted by manipulating the reliability of one predictor, the sample sizes, and the correlation between predictors. The model used in current study included only two predictors. The results showed that the higher the reliability of predictor measurement, the lower the bias of estimates of the two predictors and the type 1 error rates. Increasing reliability was also followed by increased power. Author also demonstrated that the minimum reliability to achieve desired results should be .8 to .9, not .7 as suggested by others.

Aims

Aortic prosthesis-patient mismatch (PPM) increases left ventricular (LV) afterload and prevents LV mass regression (LVMR) after surgery. This study was designed to investigate the association between the baseline global longitudinal strain (GLS) and the postoperative LVMR, and its relation to adverse outcomes.

Methods

A total of 316 patients with aortic stenosis undergoing isolated mechanical prosthesis implantation were screened, and data from 91 patients with aortic PPM and 165 non-PPM patients were retrospectively collected. All 256 patients underwent measurement of GLS by two-dimensional speckle-tracking echocardiography preoperatively, and were followed up for postoperative changes of LV mass index (LVMi) and other clinical outcomes.

Results

During the follow-up, LVMi in PPM patients decreased significantly from 139.6 ± 20.8 to 119.6 ± 26.5 g/m2 (P < 0.001). These patients were divided into two groups according to the median value of the reduction rate of LVMi at final follow-up, and preoperative GLS markedly decreased in PPM patients with insignificant reduction in LVMi. Multivariate analysis identified preoperative GLS (odds ratio 3.45, 95% confidence interval 1.27–11.05, P = 0.002) and preoperative LVMi (odds ratio 2.87, 95% confidence interval 1.21–8.13, P = 0.012) as independently associated with an insignificant LVMR. Moreover, PPM patients with limited reduction in LVMi were at an increased risk of cardiac death and major adverse valve-related events.

Conclusion

In patients with aortic PPM early after surgery, reduced preoperative GLS could be a novel sensitive risk factor for a limited regression of LV hypertrophy, and this is associated with an increased risk of adverse events in PPM patients.
