Günümüz dünyasında ve ülkelerin artan rekabet koşullarında turizme yönelik olarak daha fazla pay almak istemeleri turizm ürününün çeşitlendirilmesine yönelik önemli bir strateji haline gelmiştir. Bireyler, zaman kısıtı, maddi gerekçeler, uzman sağlık hizmeti vb. arayışlarla da turizmin ayrı bir branşı olan sağlık turizmi hareketine yönelmektedirler. Bu hususta başta Hindistan, Tayland, Singapur vb. Orta Asya ülkeleri olmak üzere dünyanın birçok bölgesinde ülkeler bu yeni sektörden pay alabilmek amacıyla yarış halindedir. Ülkelerin konforlu, ekonomik ve uzman sağlık hizmeti sunumu sektörde sağlık turistlerince tercih edilebilir olmasını sağlayan önemli kriterlerdendir. Türkiye’de birçok diğer ülke gibi sektörde kendini göstermeye çalışan bir ülkedir. Kaliteli sağlık tesisi altyapısı, uzman sağlık personeli ve ekonomik sağlık hizmeti sunumu bu alanda ülkemizin önemli avantajları olarak görülse de sağlık turizmi yalnızca bu kıstaslardan ibaret değildir. Sağlık turistlerinin bir aracı kuruluş ile ülkeye giriş yaptığı ve hastane dışında da termal tesisler, konaklama tesisleri, rekreasyon alanları gibi birçok alanda hizmet aldığı düşünüldüğünde seyahatin başından sonuna kadar personelden memnun kalma hususu önem arz etmektedir. Sağlık turistinin her alanda profesyonel hizmet alabilmesi için sağlık turizmi bilgisine ve yetkinliğine sahip nitelikli personel yetiştirilmesi oldukça önemlidir. Bu çalışmanın amacı sağlık turizmi sektörüne yönelik insangücü yetiştiren ve ülkemizde 9 üniversitede aktif eğitim veren Sağlık Turizmi İşletmeciliği Ön Lisans Programlarının müfredatlarının incelenerek çağın gereksinimlerine uygun bir eğitim almalarını sağlayacak ortak bir müfredat önerisi vermek ve eğitimde bütünlük hedeflenmiştir. Çalışma verileri nitel araştırma yöntemi ve doküman analizi tekniğiyle analiz edilmiştir. Sağlık turizmi sektörünün hizmet sunumu ihtiyacına yönelik nitelikli insangücünün yetiştirilmesine katkı sağlanmasına yönelik öneriler sunulmuştur.

Background: With improvement in living conditions in the population and the availability of treatments for various communicable and non-communicable diseases, the life expectancy and consequently the elderly population have increased. Stress leads to mental and physical problems.

Aim and Objective: The aim of this study was to assess the effect of stress on muscle functions in the elderly.

Materials and Methods: One hundred apparently healthy persons (50 males and 50 females) took part in the study. Perceived stress scale was used to measure their level of stress. Maximum voluntary contraction (MVC) and endurance time were measured with the help of a handgrip dynamometer.

Results: The elderly population sample in our study showed a moderate level of stress, but there was no significant difference between the three age groups under study.

Conclusion: A significant positive correlation between MVC and stress level was observed in our study subjects.
Effect of 6 Hz theta frequency binaural beats on post-exercise heart rate and blood pressure recovery
Authors: Pandey Mansi , Saluja Ajay , Shrivastava Ruchi , Sinha Mitesh
Published: December 2022

Background: Binaural beats are an auditory illusion which causes entrainment of various brain waves in the central nervous system which corresponds to various mind consciousness levels. Six Hz binaural beats have found to be causing entrainment similar to that in relaxation techniques such as meditation. Post-exercise recovery of heart rate is a prognostic indicator of various clinical health. The study investigated the effect of presentation of theta binaural beats on post-exercise recovery of heart rate and blood pressure.

Aims and Objectives: This study aims to compare the effect of 6 Hz theta frequency binaural beats to placebo music on post-exercise blood pressure and heart rate recovery.

Materials and Methods: It is an observational cross-sectional study in which subjects were enrolled for two sessions of maximal exercise till 70% VO2 max which was followed by presentation of either binaural beats or placebo during the relaxation period. Recording of heart rate recovery time (HRT) and heart rate recovery ratio and systolic blood pressure recovery time with systolic blood pressure recovery ratio (SBPR1 and SBPR3) were calculated. All data were analyzed using paired t-test.

Results: Forty subjects participated out of which 25 were male and 15 were female. HRT was significantly decreased in the participants when presented with binaural beats as compared to placebo. No significant difference was seen in blood pressure recovery time. Among the participants, the subjects performing moderate physical activity showed increased fall in heart rate and blood pressure in the 1st and 3rd s measured by the recovery ratio. No significant difference was seen in slight and vigorous physical activity subjects.

Conclusion: Theta binaural beats presented in post-exercise period hasten the heart rate and blood pressure recovery suggestive of entrainment of theta waves which correspond to brain waves similar to that during relaxation techniques such as meditation probably by increasing sympathetic withdrawal and parasympathetic activation.
A cross-sectional study to assess the knowledge, attitude, and practice of health-care professionals regarding reporting of medical device-related adverse events in a tertiary care center
Authors: Srinivas Mangala , Krishnegowda Scandashree , Udaykumar Padmaja
Published: December 2022

Background: Medical device-related adverse events (MDAEs) are associated to have serious consequences on consumers; therefore, post-marketing surveillance is essential to ensure the quality and evaluate the safety and performance of medical devices. The first step toward achieving this is awareness about materiovigilance and MDAEs among health-care professionals.

Aim and Objective: The aim of this study was to assess the knowledge, attitude, and practice of health-care professionals (HCPs) toward MDAEs and its reporting.

Materials and Methods: Details and purpose of the study were explained to the health-care professionals and informed consent with questionnaire was sent to the participant through Google forms link, through Email, or WhatsApp. The questionnaire consisted of 17 questions in total.

Results: Among the HCPs (n = 243) the knowledge level was 67.7% indicating moderate levels of knowledge. About 90% of participants think that medical devices can cause adverse event in patients and 78% think that it is a professional obligation to report them. About 70% of HCPs observe their patients for MDAEs; nonetheless, only 28% have reported them.

Conclusion: Healthcare professionals in our tertiary care center have moderate knowledge and positive attitude toward materiovigilance and MDAEs reporting, but, unfortunately, the actual practice of MDAE reporting is still deficient among them. Therefore, the study suggests that there is need for interventional education and training to improve the knowledge and reporting.
Early embryonic death in Equines and Camelids
Authors: Ashraf Rehan , Rashid Saba , Rasheed Imaad , Asif Sana
Published: December 2022

This paper includes the study about early embryonic death, predisposing factors of early embryonic death and treatment. Early embryonic death refers to the fetal mortality which varies in mare and camelids but most probably not later than 50 days of gestation. This duration may be divided into very early mortality, early mortality, and late embryonic mortality. This also varies in mare and camelids. There are different embryonic, maternal, environmental/external, infectious, and noninfectious factors which lead to early embryonic loss. Diagnosis is very difficult as in most of the cases resorption of fetus occurs, but it is done using ultrasound machine. Unfortunately, there is no treatment to avoid early embryonic mortality. However, new reproductive technologies have increased the service rate in a herd, and efforts are still being made to determine the rate and frequency of camel embryonic loss.
Partial lung lobectomy with the Caiman® Seal & Cut device in a dog with spontaneous pneumothorax: case report
Authors: Zobel Anne , Rohwedder Thomas , ttcher Peter
Published: December 2022

Background: Spontaneous pneumothorax in dogs is characterized by an accumulation of air in the interpleural space without an underlying trauma and consecutive acute onset of respiratory distress. Underlying causes for spontaneous pneumothorax vary with ruptured bullae being one of the main causes. Treatment after initial stabilization often requires partial or complete surgical resection of effected lung lobes. Partial lung lobectomy can be performed with stapling devices or sealing devices e.g. by different surgical approaches including video-assisted thoracoscopic surgery. However, intra-thoracic surgery in small sized dogs using either of the techniques is challenging.
Case Description: A 12 year old Shih Tzu was presented with spontaneous pneumothorax. Further diagnostics with computed tomography and intercostal thoracoscopy revealed a bulla in the right middle lung lobe. Partial lung lobectomy (2,5cm x 2,5 cm x 2cm) of the respective lung lobe was performed by an intercostal approach using the Caiman® 5 Seal & Cut sealing device. The Caiman® 5 Seal & Cut device allowed quick and safe partial lung lobectomy in the treatment of spontaneous pneumothorax without intra- or post-operative complications. The dog was discharged 2 days after surgery in good clinical condition. This report demonstrates the in-vivo efficacy and safety of the Caiman® 5 Seal & Cut sealing device for partial lung lobectomy in a small breed dog.
Conclusion: Using the Caiman® 5 Seal & Cut device lung tissue could be resected without intra- or post-operative complications in a small breed dog. The present case may emphasize the use of the device in fully video-assisted thoracoscopic surgery also in small sized patients.

Published: December 2022

Background: Intensity-modulated radiotherapy (IMRT), which allows generating steep dose gradients, is a beneficial treatment for companion animals with adjacent target and risk organs. IMRT is essential for high setup accuracy for avoiding overdose to risk organs, and optimal radiotherapy is important for evaluating the setup accuracy of companion animals.
Aim: To use an immobilization device to evaluate setup errors in radiotherapy for companion animals
Materials and methods: We calculated setup errors in radiotherapy for 386 animals (dogs and cats; 3261 registration images) that underwent radiotherapy between 2016 and 2022. The companion animals were immobilized with a customized bite block and vacuum lock device. A quantile–quantile plot with 95% confidence interval (CI) was used to evaluate the histogram of the setup errors, and the systematic and random setup errors were calculated for each region (brain, head and neck, chest and abdomen, pelvis, and spine).
Results: The setup error in each direction presented an extremely narrow-interval histogram, with the following lower and upper 95% CIs: cranial–caudal (−0.08, −0.06 cm); left–right (−0.04, −0.02 cm); and dorsal–ventral (−0.13, −0.11 cm). The mean systematic setup error was 0.16 cm (range: 0.12–0.36 cm), and the random error was 0.15 cm (range: 0.08–0.34 cm). The pelvis showed the highest systematic and random setup errors (mean: 0.36 and 0.23 cm, respectively).
Conclusion: The use of an immobilization device enables highly accurate radiotherapy for companion animals (95% CI < 0.15 cm).

Authors: Aliyev Pelin
Published: December 2022

Bu çalışmanın amacı, Kongo Demokratik Cumhuriyeti'nde siyasi istikrarsızlığın insani güvensizlik üzerindeki etkisini çocuk asker özelinde analiz etmektir. Silahlı çatışmalara zorla veya gönüllü, doğrudan veya dolaylı olarak dâhil edilen 18 yaşından küçük erkek veya kız çocuklarına çocuk asker denir. Günümüzde sayıları yüz binleri aşan çocuk askerler kötü muamelelere maruz kalmakta, ihmal ve suiistimal edilmekte, temel haklarından mahrum bırakılmaktadırlar. Silahlı çatışmalara çocukların katılımı yeni olmasa da günümüzde çocuk askerlik yaygın bir olgudur ve özellikle siyasi istikrarsızlığın yaygın olduğu gelişmekte olan ülkelerde yaygındır. Bu ülkelerden biri de Kongo Demokratik Cumhuriyeti’dir. Reformların gecikmesi, iktidar ve muhalefet arasında yaşanan hükümet krizi ve 1994 Ruanda İç Savaşı’nın sonucunda ülke büyük bir siyasi istikrarsızlığa sürüklenmiştir. Bu çalışma, Kongo Demokratik Cumhuriyeti’ndeki çocuk askerlik olgusunu bir insani güvenlik sorunu olarak ele almakta ve çocukların asker olarak kullanılmasının en önemli kaynağının ülkedeki siyasi istikrarsızlık olduğunu vurgulamaktadır. Kongo Demokratik Cumhuriyeti’nde süregelen siyasi istikrarsızlık nedeniyle, ulusal önlem ve çabaların yanı sıra mevcut uluslararası hukukun çocuk asker sorununu çözmek için yeterli olmadığı ileri sürülmektedir.
Amerika Birleşik Devletleri'nin Latin Amerika Müdahaleciliğinde Saldırgan Realizm Etkisi
Authors: Gül Uğur
Published: December 2022

Coğrafi keşifler sonrası Amerika kıtası, Avrupalı devletlerin koloni ve sömürge merkezi haline gelmiştir. Avrupa’da 19. yüzyılda patlak veren Napoleon (Bonaparte) savaşları, kıtadaki dengeleri bozmuş ve bu durum Amerika kıtasında Avrupa otoritesinin sarsılmasına neden olmuştur. Otorite zayıflığı Amerika’daki bağımsızlık hareketlerini tetiklemiştir. 1776 yılında Amerika Birleşik Devletleri’nin bağımsızlığı, kıtadaki diğer uluslara da örnek olmuştur. Bu durum Amerika Birleşik Devletleri tarafından avantaja dönüştürülmüştür. Konjonktürün elverişli olması, bölgede yeni bağımsızlığını kazanan uluslar üzerinde hakimiyetin sağlanması temel amaç olmuştur. Başkan James Monroe’nin 1823 yılında dünyaya ilan ettiği doktrin, kıta üzerindeki Avrupalı devletlerin etkisini azaltırken Amerika Birleşik Devletleri’nin de müdahale politikalarının meşruiyetini sağlamıştır. Bölgede hegemonik bir yapı kurmaya çalışan Amerika Birleşik Devletleri’nin uyguladığı politikaları John J. Mearsheimer, kendisinin öncülüğünü yaptığı Saldırgan Realizm Perspektifinden açıklamaya çalışmıştır. Dış politikasında özellikle Orta Amerika ve Karayipler bölgesine yönelik politikaların en önemli belirleyicisi Amiral Alfred Thayer Mahan olmuştur. Bu çalışmada da uygulanan müdahaleci politikaların temelinde yatan Monroe Doktrini ve Mahan’ın stratejileri, Mearsheimer tarafından Saldırgan Realizm temelinde aslında devlet bekasının sağlanması için en ideal yöntemin hegemonya kurmak olduğu iddiası çerçevesinde örneklerle incelenecektir.

A Review on Polymer Based Antimicrobial Coating
Authors: Musa Najah Hafizah , Chang Zhen Hong , Teow Yeit Haan , Rosli Nur Ameera , Mohammad Abdul Wahab
Published: December 2022

Antimicrobial coatings have become a key component of the worldwide microbial infection mitigation plan. A wide range of alternatives for designing surfaces with antimicrobial qualities is now accessible, attributed to the recent developments in materials science, biotechnology, and environmental microbiology. Antimicrobial coatings have a big role to control the spread of disease, preventing microbial colonisation on the substrate used in various applications. The antimicrobial coatings could be formed on the substrate by utilizing the polymer with antimicrobial properties or incorporating the antimicrobial agents into the polymer. By manipulating the use of polymers and surrounding conditions, the antimicrobial activity of the coating could be tailored accordingly. Due to the difference in physicochemical properties of both antimicrobial polymers and agents, the antimicrobial mechanism could be demonstrated by antimicrobial agent release, antimicrobial agent retention, contact-killing, and anti-adhesion. This paper provides information on antimicrobial coatings, in terms of the synthesis methods, antimicrobial mechanism, influencing factors, and applications in various industries.

Authors: Baharuddin Nur Zafirah Aliah , Kofli Noorhisham Tan
Published: December 2022

Bedak sejuk is a local cosmetic product produced from the natural fermentation of rice and can be placed in a group of green cosmetic products. Current traditional forms of production in beads require change for modern applications i.e. compact face powder. For that reason, the initial study was executed on the formulation to change it into compact powder based on three selected parameters which were bedak sejuk contents, binding agent concentrations (ethanol) and the amount of oil-absorbing agent (virgin coconut oil) used. Data obtained were analyzed using the One Factor At Time (OFAT) based on three tests which are drop test (height and weight) and its capacity to absorb oil. Based on the results, it is found that the best formulation for compact powder formulation (lowest cracking) was found at 50% bedak sejuk composition with 0.5 mol binding agent and 0.3 ml virgin coconut oil. This study indicates that bedak sejuk has the potential to be modernized for modern applications.

Authors: Veeraiya Thivagaran , Harun Shuhaida , Manaf Mastura Abd
Published: December 2022

Xylan from natural sources such as agricultural waste can be used to produce biopolymer packaging films and reduce the use up of petrochemical film. In this study, three different agricultural wastes (oil palm frond, sugarcane bagasse and corn stover) were used to extract xylan by using various alkaline and acidic solvents. From the analysis of the composition of oil palm fronds, it was found that oil palm frond contains (%) 30.8 ± 0.4 glucan, 19.3 ± 0.3 xylan and 18.4± 0.8 lignin. The percentage of extraction of xylan with sodium hydroxide is higher than sulfuric acid and dimethyl sulfoxide. Xylan extracted with dimethyl sulfoxide contains acetyl qualifiers and is suitable for producing carboxymethyl xylan. For xylan deposition, the use of a high concentration of ethanol gave a high xylan precipitation. Finally, the film with sorbitol as a plasticizing material showed low water absorption and high tensile strength of 4,855 gs-1m-1 Pa and 26 Mpa respectively.

Authors: Harun Nurul Hidayah , Rohani Rosiah , Dzulkharnien Nur Syafiqah Farhanah
Published: December 2022

The use of nanoparticles (nps) for surface coating has increased the researcher's interest in it due to its inherent properties, especially from metal oxide such as zinc oxide (ZnO). It is ideal for combining the coating solution because of its low cost and smaller pigments. Bio-organic materials are used for synthesis of ZnO to produce green or eco-friendly products as well as to replace polymers derived from traditional petroleum. This study aimed to incorporate ZnO into the surface coating with its potential properties to be used as an effective surface coating material. This study was focused on the synthesis of ZnO from waste cooking oil (WCO) via encapsulation of ZnO with APO obtained from WCO, followed by characterization and testing for its suitability in surface coating application. The characteristics of ZnO nps were studied by using the infrared spectroscopy of Fourier transformation (FTIR), x-ray diffraction (XRD), UV spectrum (UV-Vis) and scanning electron microscope (SEM). FTIR analysis is unable to confirm the existence of ZnO nps because it does not show maximum absorption at wavelength of 421 cm-1. X-ray (XRD) shows the particles are in high amorphous conditions. ZnO nps exhibits UV-VIS absorption at a wavelength 330 nm that provides anti-UV property. Analysis from SEM showed Zn element is absent in the dispersion of ZnO-APO paint morphology. In addition, the effectiveness of the antibacterial properties of the ZnO nps for surface coating does not show any inhibition of the bacteria, methicillin-resistant Staphylococcus aureus (MRSA) and Klebsiella pneumoniae (K. pneumoniae). Therefore, better methods of production need to be examined to help in the encapsulation of ZnO nps. The suitability of the organic or inorganic surface coating material is also needed to be explored in by further characterizing the materials based on its composition, strength and effectiveness.

Published: December 2022

This study aimed to determine the production of succinic acid by using different nitrogen sources in oil palm frond (OPF) fermentation and the recovery of succinic acid. A comparison between two nitrogen sources, i.e., yeast extract and peptone, was performed and a fermentation solution containing the highest concentration of succinic acid was used to carry out the recovery process. Activated carbon treatment at 4% to 6% (w/w) was performed to determine the best dosage that could be used for the recovery of succinic acid in the fermentation solution. Based on the results obtained, it was found that yeast extract was able to produce a higher concentration of succinic acid at 2.62 g/L with a yield of 1.53 g/g, compared to peptone which afforded a concentration of 1.89 g/L with a yield of 1.10 g/g. It was also found that the dose of 5% (w/w) activated carbon was the best to increase the concentration of succinic acid and adsorb other organic acids. After the activated carbon was fed into the fermentation solution, it was found that the succinic acid content increased from 2.62 g/L to 3.43 g/L with a percentage increase of 24.7%.

Published: December 2022

This work is aimed to develop polyethersulfone (PES) nanofiltration (NF) membrane with layer-by-layer (LBL) polyelectrolytes of chitosan (CHI) and poly(acrylic acid) (PAA) for xylitol purification from fermentation broth. Different number of bilayers and type of terminating layer were manipulated for producing more hydrophilicity, negatively charged with improved performance compared to pristine PES membrane. Successful deposition of polyelectrolyte layers onto PES membrane was able to be proven using various tests such as contact angle, Zetasizer and FT-IR. The results obtained have proven that LBL can develop PES membrane with higher resistance to fouling. From Zeta potential analysis, the value of pristine PES membrane's negativity confirmed the theory of negatively charged substrate for LDL. The negative value of PES membrane increased from -16.5 mV to -32.7 mV after being modified to PES (CHI/PAA)6. From FT-IR spectra, the formation of CHI/PAA complexes on the membrane's surface is confirmed through the presence of stretching peaks of -COOH, -NH3+ and -NH2+ groups The pure water flux reduces from 47.40 ±6.30 L⁄m2.h to 7.40 ±1.64 L⁄m2.h after being modified to PES (CHI/PAA)2. The rejection performance of xylitol for PES (CHI/PAA)2 is higher (84.95%) than pure PES membrane (66.17%), while (CHI/PAA)4 offered the lowest selectivity towards xylitol than arabinose and thus able to obtain higher purity of xylitol as retentate. LBL surface modification using CHI/PAA can develop PES membrane with higher hydrophilicity, negatively charge, and is able to give better xylitol rejection compared to pure PES.

This study aimed to determine the challenges encountered by pre-service teachers in the writing process and the coping strategies they used to cope with these challenges. For this purpose, being one of the qualitative research methods, the case study was used. Based on existing writing models in the literature, the study group of the research included 69 third-year pre service teachers who studied in the Turkish Language Teaching program of a state university during the 2018-2019 academic year. Prior to the data collection, the participants were asked to write a 1500-2000-word essay in the triangle of “reader-writer-context”. Next, they were asked to answer two open-ended questions were asked and they were asked to answer these questions and descriptive analysis technique was used to analyze the data. When the writing difficulties experienced by the pre-service teachers in the writing process were examined, it was determined that they had the most writing challenges at the process level, followed by the writing difficulties at the control level, and the least at the resource level. Coping strategies used by pre-service teachers in response to their writing challenges in the writing process, it was determined that coping strategies aimed at providing cognitive support were used the most, which was followed by coping strategies towards providing instrumental support, and strategies towards creating affective support. In conclusion, problems encountered in the professional training process and the ability to come up with solutions for these problems will be the predictor of the potential resolutions created by pre-service teachers for the problems they might face while performing their own professions.

The Critical Significance of Boron Mine in Future Energy Technologies
Authors: ARLI Fatih
Published: December 2022

The boron element forms more than 600 compounds with different element roots and shows very different properties. Boron compounds with these different properties deserve to be the most crucial strategic feature in the world as they meet the demands above the targeted standards in industries such as energy, structure, chemistry, weapons, and space. Today, the industries of developed countries have begun to take advantage of these energy sources due to the reduction of fossil energy resources, the inability of the industry to store enough electricity for an entire facility, and the limitations imposed on environmental policies. Developing countries continue to use fossil resources, but health and environmental costs are increasing. Whether they are developed or developing countries, they have attached importance to the research of energy systems that can replace fossil energy systems, which are environmentally friendly, sustainable, and high-performance. Boron has an essential role in the energy field for the isolation, high energy value retention, fuel and ion batteries, solar panels, and high-temperature transistors. In this study, the desired properties of boron compounds in energy studies were investigated by considering the positive effects of boron on the energy demand.

Objective To investigate the effect of low frequency cerebellar repetitive transcranial magnetic stimulation (rTMS) on balance impairment in patients with cerebral infarction.Methods Thirty-two patients were randomly divided into two groups: rTMS group (n=16) and control (n=16). In the rTMS group, treatment was performed five times per week for 2 weeks (10 sessions), and in the control group, a sham coil was used with the sound and sensation of scalp similar to the rTMS coil. Patients in both groups underwent a conventional rehabilitation program. Berg Balance Scale (BBS) was used as the primary outcome measurement. Timed Up and Go test (TUG), 10-m walk test (10mWT), and Activity-specific Balance Confidence scale (ABC) were used as the secondary outcome measurement. All scales were measured at baseline (T0), after 10 sessions of rTMS (T1), and at 4 weeks after treatment completion (T2) by therapists with over 5 years of clinical experience.Results There were significant improvements between T0 and T1, and between T0 and T2, for all assessed items in the rTMS group. Whereas there were significant improvements between T0 and T1, and between T0 and T2, for the BBS and 10mWT in the control group. TUG (-4.87±5.05 vs. -0.50±2.97 seconds) and ABC score (8.10±8.33 vs. 0.16±0.97) were observed significant differences in comparison of the changes from T0 to T1 between the two group. BBS score (4.40±3.66 vs. 1.88±3.14), TUG (-4.87±4.56 vs. -0.62±2.96 seconds) and ABC score (8.22±7.70 vs. -0.09±0.86) differed significantly from T0 to T2 between the two groups.Conclusion Our findings suggest that low-frequency cerebellar rTMS is helpful for improving balance in patients with cerebral infarction, and maybe a beneficial treatment for these patients.
Hemodynamic Consideration in Intraoperative Neurophysiological Monitoring in Neuromuscular Scoliosis Surgery

Published: December 2022

Objective To prove the hypothesis that the parameters of intraoperative neurophysiological monitoring (IONM) during will be more deteriorated in neuromuscular scoliosis (NMS) than in adolescent idiopathic scoliosis (AIS).Methods This retrospective study reviewed the data of 69 patients (NMS=32, AIS=37) who underwent scoliosis surgery under IONM. The amplitude of motor evoked potentials (MEPs), and the amplitude and the latency of somatosensory evoked potentials (SEPs) were examined. Demographic, preoperative, perioperative and postoperative data were analyzed to determine whether they affected the IONM parameters for each group.Results Of the items analyzed, the bleeding amount was the only significant risk factor for SEP latency deterioration in the NMS group only. The amplitude of SEP and MEP did not correlate with the hemodynamic parameters. The NMS/AIS ratios of the bleeding-related parameters were higher in the order of bleeding amount/weight (2.62, p<0.01), bleeding amount/body mass index (2.13, p<0.01), and bleeding amount (1.56, p<0.01). This study suggests that SEP latency is more vulnerable than SEP or MEP amplitude in ischemic conditions during scoliosis surgery.Conclusion In NMS patients, it should be considered that the bleeding amount can have a critical effect on intraoperative electrophysiological deterioration.
