The complexity of the condition, lack of clear routes for patients with degloving injury of integumentary tissues, inadequate and untimely diagnosis, lack of clinical guidelines and a paucity of literature lead to a great number of failures and complications in treatment of the cohort of patients. The objective of the study was to analyze failures and complications encountered in treatment of patients with degloving injury of integumentary tissues, and identify ways for the prevention. Material and methods Medical records of 40 patients with degloving injury of integumentary tissues were retrospectively reviewed. The patients treated in trauma departments and the Burn Center in Chelyabinsk between 2008 and 2014 were divided into two groups according to the time of admission to the burn center. The first group of patients was hospitalized within 6 days of injury and over. The second group of patients was admitted to the combustiology department in the first 5 days of injury. Results Failures in diagnosis and treatment were mostly observed in patients who were admitted for treatment after 5 days of injury. Most common complications included necrosis of integumentary tissues, infected wounds, necrosis of skin autografts. Discussion Most of the complications seen in patients with extensive degloving injury of integumentary tissues resulted from organizational, diagnostic, therapeutic, strategical and technical failures, and several adverse events were associated with the severity and extent of the involved tissues. Conclusion A number of recommendations have been offered for prevention of failures and complications in treatment of the cohort of patients.

Published: March 2022

Se adelanta un artículo de revisión sobre la educación virtual colombiana en tiempos da pandemia, con el objetivo de observar los distintos modos como las instituciones de educación universitaria han procurado abordar las exigencias que representan el dar continuidad a la prestación de los servicios educativos en tiempos de pandemia. La revisión se adelanta a 32 universidades colombinas a partir de la revisión a los documentos oficiales publicados en sus páginas web sobre las medidas tomadas para dar continuidad a los procesos educativos durante la pandemia del COVID 19 durante la vigencia del primer semestre del 2020. Se concluye que las IES colombianas si bien están convocadas por políticas globales y nacionales a aportar a la disminución de la brecha digital, se encuentran casos que o bien deben dar paso a superar el paradigma de la educación presencial como única mediación posible para el aprendizaje o aún están lejos de lograr las condiciones tanto de infraestructura tecnológica como de personal docente capacitado para ser actor activo en la formación mediada por Tecnologías de información y comunicación – TIC.

Published: March 2022

Electrocution deaths (EDs) is one of the important causes of negative autopsy with no gross pathological findings in almost half of all cases. The history surrounding the cause of death and circumstantial evidence is sometimes ambiguous and poses great difficulty. Hence, this need to be coupled with histopathological examination to arrive at the diagnosis.

: Retrospective study was conducted with entry and exit wound of skin samples among 17 cases of EDs Total- 46 skin samples. Corresponding normal skin was used as control. The histomorphological changes of skin were noted in both entry and exit wound separately and its association with electrical voltage was studied and statistically analysed.

: The maximum EDs were due to high voltage (47.06%) at the workplace (70.5%) and were accidental in nature (100%) predominantly affecting males (88.24%). Upper extremity was the chief area of wounding (51.7%). Most common gross abnormality was ulcer/crater (82%) in entry wound followed by bulla formation (70%). Commonly exit wound showed splits in skin (75%). The most common histopathological finding in entry as well as exit wound was dermoepidermal separation (88%, 75%), coagulative necrosis of epidermis (82%, 66%) and nuclear streaming (76%, 50%) respectively.

: Histopathological changes in skin give the supportive evidence in determining the cause of death especially in case of negative autopsy. The important microscopic features of electrocution are dermoepidermal separation, coagulative necrosis, and nuclear streaming.

Published: March 2022

The aim of this study is to investigate and quantify the aerodynamics advantage, the physiological and performance advantage produced by pacemaker drafting in the case of long endurance running. The experimental tests have been carried out in a wind tunnel, at submaximal effort two runners done a treadmill run test of five minutes at 4.72 m/s with the same air velocity. By comparison of physiological parameters with and without drafting, the decreasing due to the pacemaker effect was obtained. A CFD simulation is used to analyze aerodynamic effects in terms of drag and drag coefficient with and without drafting at a wind speed of 4.72 m/s. Results indicates that compared to the baseline (running alone), the drafting position show a decrease in drag (-9.73%) and drag coefficient (-9.73%). This reduction in aerodynamic drag also leads to the reduction of the following physiological parameters, as detected by the experimental tests: oxygen consumption (-5.46%), metabolic power (-5.48%), energy cost (-7.31%), produced carbon dioxide (-7.40%), minute ventilation (-5.44%), HR (-0.60%), blood lactate concentration (-16.66%), RPE (-13.89%). Results demonstrate that drafting has a significant effect on aerodynamics parameters, but also on physiological and performance variables in highly and medium trained athletes.

Authors: Ibrahim Habiba A. , Ammar Hossam Hassan , Shalaby Raafat
Published: March 2022

The field of rehabilitation robotics for upper limb assistance has grown rapidly in the past few years. Rehabilitation robots have direct contact with human joints, which presents a serious safety concern. In this paper, a novel design for a series elastic actuator (SEA) is presented for upper limb rehabilitation of sensorimotor dysfunctions. The proposed SEA ensures safety and robust torque control under various disturbances. The proposed SEA is modeled and simulated using MATLAB Simulink to obtain Input/Output driven data. For the proposed system, two modeling approaches, ARMAX and NN, are used along with comparative analysis for each model fitting. After SEA dynamic modeling, the PSO-tuned LQR controller is designed and implemented. Comparison parameters are then chosen to test the controller behavior during different applied disturbances. The chosen controller showed optimum set-point tracking performance, which is equivalent to upper limb movement. This research can be extended to develop and implement a test bench for upper limb rehabilitation.
PI Optimized Cuckoo Search Algorithm for Single Phase Grid Tied PV Inverter with SEPIC Converter
Authors: Barathi K. , Dhal P.K.
Published: March 2022

A new approach for single phase grid interconnected PV module with SEPIC converter is introduced in this paper. As the outcome of PV is low voltage DC, a suitable converter is needed to boost the voltage. Hence SEPIC converter is used as it has high voltage gain with same polarity in the input as well as output side. A closed loop control is executed with a PI controller tuned with Cuckoo search (CS) algorithm. As the traditional tuning of PI controller results in peak overshoot problems, Cuckoo search (CS) based Optimization is utilized as it is simple with has a smaller number of tuning parameters. This output is being fed to the grid through a single phase VSI and the grid synchronization is accomplished by PI controller by analogizing the actual and reference values of power. Thus, the proposed control strategy is verified through MATLAB and it is observed that the source current THD is minimized, which satisfies the IEEE standard.

Durante as últimas décadas, estudos envolvendo a estrutura bainítica tem atraído pesquisadores por combinar elevada resistência e alta ductilidade. Aços bainiticos são potencialmente úteis em estruturas que sofrem fadiga de rolamento e/ou deslizamento, por exemplo trilhos ferroviários, componentes de mineração, rolamentos e eixos. Essas propriedades mecânicas têm sido obtidas, elaborando cuidadosamente o projeto da liga e adequado tratamento térmico de austêmpera. No entanto, o material com essas propriedades tende a prejudicar a usinabilidade nos processos de manufatura, fazendo-se necessário usinar o material no estado recozido. Este trabalho tem por objetivo contribuir com a análise tribológica do contato entre aço fundido no estado recozido contra metal duro e cermet (revestidos com Nitreto de Titânio (TiN)), que são materiais amplamente encontrados em ferramentas de corte. Para isso, foram realizados ensaios de pino sobre disco (PSD), de modo a analisar as evoluções do coeficiente de atrito (µ), coeficiente de desgaste específico (k) e o comportamento de induzidas deformações. Os resultados indicaram que os menores valores de µ foram observados utilizando pinos com substrato de cermet, o que sugere ter sido influenciado pela composição química desse substrato. Em relação ao k e a espessura da camada deformada para ambos os substratos não houveram variação significativa nos valores encontrados. Superfícies lisas foram observadas para as trilhas desgastadas em todas as condições avaliadas e sinais de deformação plástica (ploughing) no qual sugere atuação de suaves mecanismos de abrasão. No entanto, foi observado que tanto o mecanismo de adesão quanto o mecanismo de abrasão influenciaram o µ para o substrato de cermet na condição réplica. O trabalho contribui para avaliar a influência de diferentes substratos e identificação dos mecanismos de desgaste presente.

Authors: YAKAR Burkay , PİRİNÇCİ Edibe , ŞEN Mehmet Ali , YARAŞIR Ezgi
Published: March 2022

Objectives: Testicular tumors are the most common malign tumor in men aged 15-35 years. Early diagnosis and treatment is crucial in testicular cancer because if detected at an early stage, testicular cancer can be completely cured. Because of this reason increase in awareness and regular testicular self-examination (TSE) is recommended in the early diagnosis of testicular cancer. This study aimed to investigate the knowledge, attitude and behaviors of students about testicular cancer and testicular self-examination.
Methods: This descriptive and cross-sectional study was conducted in Health care vocational schools of 2 different universities between November 2018 and January 2019. Data were obtained by a self-applied questionnaire comprised of four sections.
Results: One hundred and six (37.7%) participants could not answer any question correctly. While 65.8% (n = 185) of the participants stated that they had heard of testicular cancer, the rate of those who heard about TSE was 17.8% (n = 50). Only 5.7% (n = 16) of the participants reported performing TSE. Binary logistic regression analysis was shown that the following factors increase men’s intention to perform TSE: Students’ academic unit [OR  =  4.36, 95% CI: 1.37-13.88], age [OR  =  0.2; 95% CI: 0.008-0.72], city [OR  = 0.64; 95% CI: 1.15-1.49], those who have heard of TC before [OR  =  0.71, 95% CI: 0.016-0.917], received information about TC [OR  =  0.001, 95% CI: 0.015-0.309], and those who have heard of TSE before [OR  =  0.01; 95% CI: 0.001-0.079].
Conclusions: One-third of the university students had never heard of testicular cancer, ‎and TSE was not sufficiently practiced. There is a lack of information on this issue. It was thought that organizing training programs on the subject would raise awareness and save lives by early diagnosis.
Implementing the Marketing Plan: How Depth-of-Engagement in Community-Based Learning Impacts Students and Their Nonprofit Partners
Authors: Schneider Abigail B.
Published: March 2022

Marketing and soft skills are increasingly important for success in the nonprofit sector. As such, marketing and fundraising plans are among the most widely assigned experiential projects in nonprofit education programs; yet they often occur with a low level of interaction, culminating in students’ presenting the plan to nonprofit leaders. Rarely do students interact at higher levels such as by working with the nonprofit to raise funds. The purpose of the current study is to compare the benefits afforded by two different pedagogical approaches—one that involves a project where students simply write a marketing plan and one that involves a project where students also implement the marketing plan—and to explore how higher-level interaction, compared with lower-level interaction, impacts perceived student learning, actual student learning, and the tangible value created for the nonprofit partner. Importantly, the projects are suitable for students with little or no prior marketing experience.

Authors: Alzubi Emad , Attiat Madher Mohammad , Al-Adamat Omar Atallah
Published: March 2022

This study aimed to investigate the role of systemic intelligence factors in explaining cognitive flexibility and cognitive holding power among university students using measures of the aforementioned phenomena. A random sample of (519) students participated in this research, and it was found that factors relating to systemic intelligence could predict cognitive flexibility and cognitive holding power. The elements of systemic intelligence that were most adept at explaining cognitive flexibility were systemic action through positive engagement and active response, while systemic perception was the most explanatory factor in terms of cognitive holding power. The study concluded that systemic intelligence, which has perceptual, cognitive, social and behavioural facets, contributes to student performance in learning settings; consequently, it is recommended that the role of systemic intelligence should be analysed by linking elements of this form of intelligence with the different variables and integrating systemic thinking skills into different learning activities.

 

Keywords: systemic intelligence, cognitive flexibility, cognitive holding power.

Published: March 2022

This study aims to analyze the efficiency and effectiveness of the management of zakat and infaq/alms at the National Board of Zakat (Baznas) West Java for 2015-2019. Measuring efficiency uses a data envelopment analysis (DEA) approach. Measurement of effectiveness uses an allocation-to-collection ratio (ACR) approach. Data obtained from Baznas West Java comes from financial reports for the 2015-2019 period. The results showed the value of the efficiency of zakat management in the efficient category. The efficiency value in the 2016-2019 range reaches 100% each year. Then, the value of zakat distribution's effectiveness for the 2015-2019 period is in the highly effective category. The value of the effectiveness of infaq/alms distribution for the 2015-2019 period is in the effective category. The effectiveness of zakat distribution every year is bellows expectation (2015), effective (2016), highly effective (2017), highly effective (2018), and highly effective (2019). The effectiveness of infaq/alms distribution every year is effective (2015), fairly effective (2016), effective (2017), bellows expectation (2018), and highly effective (2019). The implication of this research is to increase public trust and confidence that the zakat they pay has and will be used efficiently and effectively by zakat management organizations. Then, suppose it is associated with Sharia Enterprise Theory. In that case, this study's implications refer to and strengthen the exogenous variables, namely accountability and transparency of financial reporting, which are the motivating factors for muzakki to pay their zakat to the Zakat Management Organization.

Keberadaan pembiayaan Murabahah di perbankan syari’ah bagaikan pisau bermata dua. Satu sisi, produk murabahah selalu menjadi produk unggulan dan menjadi primadona bagi bank syariah. Di sisi lain, salah satu produk utama bank syari’ah ini senantiasa mendapat kritik tajam dari berbagai elemen. Bagi sebagian kalangan, penerapan pembiayaan Murabahah secara dominan, akan semakin membuktikan bawha bank syari’ah tidak jauh berbeda dengan bank konvensional yang menerapkan sistem bunga. Produk berbasis bagi hasil seharusnya menjadi produk utama dan diutamakan untuk menghantam institusi riba. Akibatnya, Murabahah di bank syari’ah dianggap transaksi mirip bunga pada bank konvensional. Namun demikian, berdasarkan analisis metodologi pengembangan dan peningkatan (kualitas) produk dari perspektif syari’ah, ”rekayasa produk” untuk menyesuaikan diri supaya tidak bertentangan dengan syari’at Islam dapat dibenarkan

Published: March 2022

Background: Pleomorphic adenoma (PA) is a benign salivary gland tumour with high incidence and recurrence after treatment. It may recur with the same appearance or develop toward malignancy, namely as carcinoma ex pleomorphic adenoma (CXPA). Howthis tumour can transform into a CXPA remains unclear. Purpose: The aim of this study was to analyse the possibility of pathogenesis and progressivity of PA to CXPA. Methods: Twenty-four samples of PA and three control samples of CXPA were stained with haematoxylin and eosin (HE), Mallory’s trichrome, and Periodic acid–Schiff (PAS). All of the PA cases were identified through different kinds of stroma, tumour cells types, morphologic patterns, or else through atypical appearance of the PA similar to the CXPA. Results: Twenty-four samples of PA demonstrated that the most dominant stroma was myxofibrous, and the dominant tumour cell type was plasmacytoid cells with a trabecular pattern. Additionally, in the pleomorphic histological picture of adenomas we found several patterns of malignant tumour behaviour, including pseudopodia, metaplasia and hyalinisation, and cholesterol crystals that are thought to come from fat cell necrosis derived from adipose metaplasia. Conclusions: PA displays several atypical characteristics that have the potential to develop into malignancies such as CXPA, due to capsular infiltration, necrosis, hyalinization and high mitotic activity of cells, but all these atypical characteristics that we observed still cannot be clearly classified as CXPA because they require other specific examinations.

Authors: Hutomo Suryani , Sooai Christiane Marlene , Merry Maria Silvia , Larope Ceny Gloria , Kristiyanto Haryo Dimasto
Published: March 2022

Background: Candida albicans (C. albicans) is an opportunistic pathogen that can be found in the oral cavity and other parts of the body. This species is the main cause of oral candidiasis and forms a biofilm as its virulence factor. Due to increasing cases of antifungal resistance, research is needed on methods to control Candida biofilm formation. Brotowali (Tinospora crispa L.) is known to be antifungal, antiseptic and antiparasitic. Purpose: The purpose of this study is to analyse the ability of brotowali stem extract to inhibit Candida biofilm formation. Methods: The susceptibility of C. albicans to this extract was examined by a minimum inhibitory concentration (MIC) test using the broth microdilution method. A bacterial adherence assay was performed by similar methods of the MIC assay. A brotowali stem extract of various concentrations were incubated in a yeast peptone dextrose broth medium and stimulated with a C. albicans suspension. The 0.1% crystal violet was used to stain the adherent fungi and measured using a microplate reader at 595 nm. Scanning electron microscopy (SEM) was performed to provide a general overview of the biofilm formation. Results: The MIC value for the brotowali stem extract was at a concentration of 5,000 μg/ml. Moreover, this extract inhibited fungal adherence starting at a concentration of 250 μg/ml. Observation using SEM confirmed these results. Statistical analysis using one-way analysis of variance demonstrated a significant difference of C. albicans adherence following stimulation with brotowali extract (p < 0.005). Conclusion: Brotowali stem extract can inhibit C. albicans biofilm formation at an optimal concentration of 1,000 μg/ml.

Authors: Wulandari Erawati , Wardani Farah Rachmah Aulia , Fatimattuzahro Nadie , Dewanti I Dewa Ayu Ratna
Published: March 2022

Background: Porosity is one of the disadvantages of glass ionomer cement (GIC) restorative materials, as it causes a reduction in strength and durability; the greater the porosity, the lower the strength of the restorative material and vice versa. As gourami fish scales contain calcium and phosphate, they have the potential to reduce the porosity of GIC. Purpose: This study aimed to analyse the effect of adding gourami fish scale powder (GFSP) on the pore size and porosity level of the GIC. Methods: This experimental research included a post-test-only control. The GFSP was fabricated using the freeze-drying method. Sixteen Fuji IX Extra sample cylinders with a diameter of 5 mm and a height of 3 mm were divided into four groups: K0, which comprised GIC without the addition of GFSP; K1, which contained GIC powder + 2.5% GFSP (by weight); K2, which comprised GIC powder + 5% GFSP (by weight), and K3, which contained GIC powder + 10% GFSP (by weight). The samples were observed using scanning electron microscopy and measured using ImageJ software. Data were analysed using a one-way analysis of variance (ANOVA) test. Results: The addition of 2.5% GFSP (by weight) produced the smallest pore size and lowest porosity, while the one-way ANOVA test results were significant among all groups at p = 0.000. There was no significant difference in pore sizes between K0 and K1 (p = 0.359), but a significant difference was found in the level of porosity (p = 0.024). Conclusion: The addition of GFSP affected the porosity of the GIC; the pore size and porosity level of the GIC were reduced by the addition of 2.5% GFSP.

Authors: Irmawati Anis , Rachma Lia Aulia , Sidarningsih S. , Hatta Muhammad Naufal , Arundina Ira , Aljunaid Mohammed
Published: March 2022

Background: Cancer is a major cause of death worldwide. One of the most common forms of cancer is oral cancer, which can occur due to exposure to carcinogenic factors, such as tobacco cigarettes, alcohol, betel-nut chewing, ultraviolet rays or human papillomavirus infection. Physical exercise is known to have many benefits and can contribute to reducing the risk of cancer, minimising the side-effects of treatment and increasing the curative effect of cancer treatment. Purpose: This study aimed to explain the role of exercise as a method to reduce oral cancer risk. Reviews: Studies examining the impact of exercise on reducing oral cancer risk are currently limited due to a lack of research on this subject. However, according to several laboratory experimental research studies on Mus musculus test subjects, moderate-intensity exercise contributes to suppressing the proliferation and development of oral squamous epithelial cells, which can subsequently become cancer cells. Exercise can also increase intracellular proteins that can induce apoptosis in cells (e.g. wild protein p53, the ratio of Bax/Bcl-2, and caspase-3), and can also decrease p53 mutant expression and transformed cells that can trigger cancer. Exercise must be optimally performed to prevent or control cancer symptoms, although the exact duration and intensity of exercise required to reduce cancer risk in humans have not been established. Conclusion: Exercise plays a role in reducing oral cancer risk by inducing apoptosis and preventing the development of transformed cells that can lead to developing cancer.
Origin of Steam Contaminants and Degradation of Solid-Oxide Electrolysis Stacks
Authors: Schäfer Dominik , Queda Larissa , Nischwitz Volker , Fang Qingping , Blum Ludger
Published: March 2022

Two once-through steam generators and a combination of a steam generator and a gas preheater for supplying feed gases to solid-oxide electrolysis stacks were evaluated for their carryover characteristics of contaminants from the feed-water into the steam phase. The concentrations of various trace impurities in the steam were determined by sampling the steam condensates and screening them with inductively coupled plasma - mass spectrometry for 19 elements and liquid ion chromatography and continuous flow analysis for chloride and ammonium. Steam soluble species like boric acid undergo complete volatilization and transfer into the steam phase. During unstable evaporation in the steam generators an extensive physical carryover of alloying metal species was observed. At realistic operation conditions for steam electrolysis, the gas preheater caused a considerable release of silicon into the steam phase. Two stack experiments were performed with common preheater temperatures and showed largely increased cell voltage degradation at higher operation temperatures. The post-test chemical analysis of cell samples revealed significant concentrations of silicon in the samples that are regarded as primary cause for increased degradation. These findings could partially explain the wide spread of degradation rates reported for solid-oxide steam electrolysis experiments.
High Aspartate Aminotransferase/Alanine Aminotransferase Ratio is the Conventional Biochemical Biomarker that is Most Closely Associated with All-Cause Mortality in Older People
Authors: Nakajima Kei , Yuno Mariko , Tanaka Kazumi , Nakamura Teiji
Published: March 2022

Low serum alanine aminotransferase activity and high aspartate aminotransferase (AST)/ALT ratio may be associated with high mortality in older people. We aimed to confirm this in an 8-year retrospective cohort study. Clinical data for 5,958 people aged 67–104 years were analyzed for their relationships with all-cause mortality using artificial intelligence (AI; Prediction One [Sony Network Communications Inc.]) and conventional statistical analysis (SAS Enterprise Guide [SAS Institute Inc.]). In total, 1,413 (23.7%) participants died during the study. Auto-AI analysis with five rounds of cross-validation showed that AST/ALT ratio was the third largest contributor to mortality, following age and sex. Serum albumin concentration and body mass index were the fourth and fifth largest contributors, and the individual serum ALT and AST activities were the seventh and tenth largest contributors. Conventional survival analysis showed that ALT, AST, and AST/ALT ratio as continuous variables were all associated with mortality (adjusted hazard ratios (95% confidence intervals): 0.98 (0.97–0.99), 1.02 (1.02–1.03), 1.46 (1.32–1.62), respectively; all p <0.0001). In conclusion, both AI and conventional analysis suggest that of the conventional biochemical markers, high AST/ALT ratio is most closely associated with all-cause mortality in older people.

Single-lip deep-hole drilling (SLD) is characterized by high surface quality and compressive residual stress in the subsurface of the drill hole. These properties depend significantly on the thermo-mechanical conditions in the machining process. The required subsurface properties can be adjusted in-process via process monitoring and control when the thermo-mechanical conditions are maintained in the optimum range. Herein, a sensor-integrated SLD tool is introduced, which allows the temperatures near the cutting zone to be measured and the vibrations occurring directly at the drill head to be recorded. A microcontroller-based wireless measurement data transmission method is presented.

In the machining field, the quality of a machined surface is characterized using both quantitative and sensory parameters. It is important to quantitatively evaluate sensory parameters to automate the evaluation of machined surfaces and determine the machining conditions. In this study, we quantitatively evaluate the gloss degree, which is a sensory parameter, via visual simulation. The gloss degree is evaluated based on an angular luminance distribution for machined surfaces cut using different tools. Using the quantitative evaluation result, observation is conducted to predict the appearance of the machined surface, and a sensory test is performed. The result shows that the quantitative evaluation results are consistent with the sensory test results.

México enfrenta grandes retos para la incorporación, uso y aprovechamiento de las Tecnologías de la Información y Comunicaciones (TIC) en la sociedad, en paralelo con el problema de la pobreza que afecta un amplio sector de la población. En esta investigación se realiza un análisis a partir de indicadores estadísticos de fuentes oficiales, con la finalidad de resaltar la relación entre las TIC y la pobreza convencional, con lo que se contribuye en la comprensión del concepto de pobreza digital y con ello se evidencia, que las restricciones económicas acentúan la diferenciación social. Se concluye que además de los dispositivos electrónicos, el elemento central para el aprovechamiento de las TIC, es el acceso y disponibilidad a Internet: el gasto necesario en los hogares representa una proporción importante del ingreso disponible, que para una gran parte de la población esto se traduce en quedar al margen de los beneficios de la denominada revolución digital.

Objectives. Despite sufficient hearing gains, many patients with hearing loss have difficulty using hearing aids due to poor word recognition ability. This study was performed to introduce our hearing rehabilitation therapy (HRT) program for hearing aid users and to evaluate its effect on hearing improvement.Methods. In this prospective randomized case-control study, 37 participants with moderate or moderate-severe sensorineural hearing loss who had used bilateral hearing aids for more than 3 months with sufficient functional hearing gain were enrolled in this study. Nineteen participants were randomly assigned to the control group (CG) and 18 patients were assigned to participate in our HRT program once a week for 8 consecutive weeks (hearing rehabilitation therapy group [HRTG]). Their hearing results and questionnaire scores for hearing handicap and hearing aid outcomes were prospectively collected and compared between the two groups.Results. After completing 8 weeks of the HRT program, the HRTG showed a significantly greater improvement in scores for consonant-only and consonant-vowel sound perception than the CG (P<0.05). In addition, the HRTG showed a significant improvement in hearing ability as measured by two questionnaires (p<0.05), while no differences were observed in the CG. However, word and sentence recognition test results did not show significant differences between the two groups.Conclusion. Even after short-term HRT, patients had subjectively better hearing outcomes and improved phoneme perception ability; this provides scientific evidence regarding a possible positive role for HRT programs in hearing aid users. Further validation in a larger population through a long-term follow-up study is needed.

Background:

To maintain the integrity of the match, postinterview communication (PIC) from programs to applicants is monitored and discouraged. The most recent report on the prevalence of PIC in orthopaedics found that 64% of surveyed applicants in 2014 and 2015 had received some form of PIC during their match cycle. In July 2019, the American Orthopaedic Association’s Council of Orthopaedic Residency Directors (AOA/CORD) released a guideline recommending the elimination of all PIC in any form. The goal of this follow-up study was to determine the current prevalence of PIC with orthopaedic surgery applicants and assess the perspectives of medical students who recently applied for orthopaedic surgery residency positions.

Methods:

A 35-question survey was e-mailed to all orthopaedic surgery residency applicants of 4 geographically diverse residency programs in postmatch March 2020. The survey was open for 1 month, and the responses were reported using descriptive statistics.

Results:

Of the 229 respondents (21% response rate), 91 (39.7%) received PIC during the 2019 to 2020 residency match cycle. The program director was most commonly identified (80.2%) as the person who communicated with the applicants. At the interview day, 198 respondents (86.5%) were told that programs would not be contacting the applicants with PIC. However, over a quarter of respondents (25.3%) who received PIC answered that those programs contacted applicants after announcing they would not. Nearly half of the respondents (48.5%) agreed or strongly agreed that PIC causes added stress on applicants, and over half (52.9%) agreed or strongly agreed that all programs should stop participating in any form of PIC.

Conclusions:

Although the prevalence of PIC seems to have decreased since the 2014 and 2015 match, there is still room for improvement toward eliminating PIC. The AOA/CORD position statement from July 2019 should be disseminated to all members of the residency selection team to ensure consistency from all programs. The primary limitation of this study was the 21% response rate.
