Abstract
The aim of this study was to determine the acute effects of high‐intensity cycling exercise on the variables of carotid artery compliance, distensibility and beta stiffness index in elite adolescent wrestlers. The subjects were elite athletes competing in national, European and World Championships, who attended a training camp in the province of Kahramanmaras organized by the Turkish Centre for Olympic Preparation. The study sample comprised 31 male elite wrestlers with a mean age of 15.90 ± 0.87 years, body height of 165.97 ± 9.7 cm and body mass of 66.3 ± 18.45 kg. The arterial stiffness variables of the wrestlers were measured with high‐resolution Doppler ultrasonography before and 5 min after 30 s of high‐intensity cycling exercise (the Wingate Anaerobic Cycling test). The results showed a statistically significant correlation between mean power performance and carotid artery compliance at the 5th min after a single cycling sprint exercise (p < 0.05). No correlation was determined between peak power and the arterial stiffness variables (p > 0.05). The study results indicate that acute changes in arterial stiffness variables are associated with the performance level of high‐intensity cycling exercise in a group of elite adolescent wrestlers.

Abstract
The ability to stabilize the gun, a crucial factor for performance in air pistol Olympic shooting, is thought to be strongly related to the muscular work of the shooter´s shoulder and forearm. The objective of the present study was to confirm this relationship by analysing the influence of maximal finger flexor forces and maximal isometric shoulder force on performance in female air pistol shooting. Twenty‐three female pistol shooters participated in the study. Handgrip and shoulder force data were recorded under competition conditions, during the official training time of national Spanish championships on the day previous to the competition and at the official training stands. Performance was measured as the total score of 40 shots at competition. Linear regressions between performance and age, weight, height, training experience, body mass index (BMI), mean and maximal finger flexor and shoulder forces were calculated. Significant correlations were found between performance and a) training hours b) peak finger flexor force relative to the BMI, and c) peak isometric force of the shoulder abduction relative to the BMI. The study concludes that there is a statistically significant correlation between performance and muscular forces exerted by the athletes relative to their BMI. Appropriate muscular strength training programs are therefore necessary in female air pistol Olympic shooting.

Abstract
The aim of this study was to compare the acute effects of performing half squats (HSs) with different loading intensities (1, 3, and 5 repetitions maximum [RM], and 60% 1RM) and a different number of sets (1, 2, and 3) on the countermovement jump (CMJ) performance of 18 highly‐trained male subjects. Participants were submitted to four experimental conditions (1RM, 3RM, 5RM, and 60% 1RM) in randomized order. The CMJ was assessed before and after each set. Differences in CMJ performance between the distinct experimental conditions and individual responses in CMJ performance induced by the different protocols were analyzed via the magnitude‐based inference method. Overall, significant improvements were detected in individual CMJ heights after each activation protocol. It can be concluded that the use of 1 to 3 sets of HSs performed at moderate‐to‐high loads may be an effective strategy to improve jump performance in highly‐trained subjects. Nonetheless, despite the high efficiency of the protocols tested here, coaches and researchers are strongly encouraged to perform individualized assessments within the proposed range of loads and sets, to find optimal and tailored post‐activation potentiation protocols.

Abstract
Post‐activation potentiation (PAP) has been defined as a major enhancement of muscular performance following a preload stimulus. The eccentric actions seem to cause a potentiating effect on subsequent explosive exercises. The aim of this study was to determine whether a protocol of squat exercise using an inertial flywheel could have a potentiating effect on jump performance. Sixteen physically active volunteers participated in the study (age: 21.8 ± 2.7 years; body mass index: 23.6 ± 3). All participants completed two different protocols on separate days: a Traditional Protocol (using a half squat with a guided barbell) and an Inertial Flywheel Protocol (using a half squat with an inertial flywheel). Both protocols were similar and consisted of 3 x 6 reps at the load that maximized power, with a 3‐minute rest interval between sets. The squat jump (SJ) was measured by a contact platform at baseline, and four, eight and twelve minutes after the PAP stimulus. A two‐way ANOVA with repeated measures was performed to analyze significant differences over time. There were significant increases of SJ height (p = 0.004, d = 0.665), velocity (p = 0.003, d = 0.688) and power (p = 0.004, d = 0.682) from baseline after the inertial flywheel protocol. A significant interaction effect (time x protocol) was observed, showing that the inertial flywheel protocol had a potentiating effect on the jump performance compared to the traditional protocol, more specifically at 4 and 8 minutes after the PAP stimulus. In conclusion, the inertial flywheel protocol showed a potentiating effect on the squat jump performance, thus this pre‐ conditioning activity could be useful during the warm‐up before the competition.

Abstract

Background
Radiotherapy (RT) is a successful mode of treatment for early glottic cancer. The aim of the study was to assess voice quality both before and 3 months after successful RT using multimodal methods while also identifying the factors affecting it.

Patients and methods
In 50 patients with T1 glottic carcinoma, the subjective (patients’ assessment of voice quality [VAS], Voice Handicap Index [VHI] questionnaire, phoniatricians’ assessment using the grade/roughness/ breathiness [GRB] scale), and objective assessments (fundamental laryngeal frequency [F0], jitter, shimmer, maximum phonation time [MPT]) of voice quality were performed before RT and 3 months post-RT. The data on gender, age, extent of the tumors, biopsy types, smoking, local findings, and RT were obtained from the medical documentation.

Results
Three months after the treatment, VAS, VHI, G and R scores, F0, and MPT significantly improved in comparison with their assessment prior to treatment. Before the treatment, the involvement of the anterior commissure significantly deteriorated jitter (p = 0.044) and the involvement of both vocal folds deteriorated jitter (p = 0.003) and shimmer (p = 0.007). After the RT, F0 was significantly higher in the patients with repeated biopsy than in the others (p = 0.047). In patients with post-RT changes, the B score was significantly higher than in those without post-RT changes (p = 0.029).

Conclusions
Voice quality already significantly improved three months after the treatment of glottic cancer. The main reason for the decreased voice quality prior to treatment is the tumor’s extent. Post-RT laryngeal changes and repeated biopsies caused more scarring on vocal folds adversely influencing voice quality after the treatment.
Two Sided Markets: The Case of The Waterbed Effect in OECD Mobile Telecommunications Markets
Authors: KAR Mikail 
Published: October 2019

Efforts to develop appropriate policies and accurate strategies
through the most accurate analyzes highlight the examination of two-sided
markets, which differ significantly from one-sided markets. In this study,
mobile telecommunications market which has a special place in two-sided market
analysis will be studied. In mobile telecommunications market, it is suggested
that a reduction in mobile interconnection rates for the interconnection
service will show the waterbed effect, resulting in an increase in mobile
communication prices that the end user faces in the market. In this context, an
empirical analysis was made by Common Correlated Effects Mean Group (CCEMG)
estimator using the 41 quarter period data of 21 OECD countries between 2005
and 2015, and the effect of mobile interconnection rates, income and quantity
were estimated in determining the mobile communication prices. According to the
results, the waterbed effect in mobile telecommunications markets could not be
determined in the period analyzed for the related country group and mobile
interconnection rates acted as a cost factor and changed the prices in the same
direction. The coefficient of income
variable was positive and the expectation that the increase in income would
increase the price was met. The
explanatory variable coefficients of the number of subscribers and the penetration
rate representing the quantity were negative and they were evaluated to behave
in accordance with economic expectations and two-sided market characteristics.

Published: October 2019

Aim: We aimed to investigate thiol/disulphide homeostasis as an additional serum marker to prostate specific antigen (PSA) in the diagnosis of prostate cancer. Patients and Methods: Prospective study was conducted among 174 patients with PSA levels of 2.5–20 ng/mL without suspicion of malignancy in rectal examination and who underwent prostate needle biopsy. A total of 75 patients were included in our study after exclusion criteria. Serum PSA, thiol, and disulphide levels of the patients were recorded prior to biopsy. In this study, 25 patients with pathology results indicating prostate cancer, 25 randomly selected patients with pathology results indicating chronic prostatitis, and 25 randomly selected patients with pathology results indicating benign prostate hyperplasia (BPH) were included. Results: Total and native thiol levels were higher in prostate cancer group than in BPH and chronic prostatitis groups; however, no statistically significant difference was observed (p&gt; 0.05). When prostate cancer sub-groups were investigated, total and native thiol levels were noted to be higher in patients with a Gleason score of 7, 8, and 9 than in those with a Gleason score of 6; however, no statistically significant difference was observed (p&gt; 0.05). Conclusions: Thiol levels were higher in prostate cancer group than in benign disease (BPH and chronic prostatitis) groups; these levels were also higher in group with high Gleason scores (Gleason 7, 8, or 9) than in group with a low Gleason score (Gleason 6); however, these differences were not statistically significant.

Authors: AYCAN Osman Emre 
Published: October 2019

Amaç: Çalışmamızda Herediter Multipl Egzostozis (HME) hasta grubunda başta ağrı olmak üzere hastalığa ait komplikasyonların çocuk ve adölesan dönemdeki etkilerini değerlendirmeyi amaçladık. Hastalar ve Yöntem: 10-19 yaş arası 72 (37Erkek/ 32Kadın) hasta değerlendirmeye dahil edildi. Ortalama yaş 13.8±2.6 idi. Hastaların demografik verileri, lezyonların ilk ortaya çıktığı yaş, lezyon sayıları, deformite varlığı ve VAS skoru ile ağrı durumları değerlendirildi. Çalışmaya katılan hastalara, ağrının yaşam kalitesi üzerine etkilerini değerlendirmeye yönelik bir anket yöneltildi. Depresyon değerlendirmesi 17 yaş ve altı hastalarda Çocuklar için Depresyon Ölçeği (ÇDÖ) ve 18 yaş ve üstü hastalar için Hamilton Depresyon Ölçeği (HAM-D) ile değerlendirildi. Grup değişkenlerinin frekans ve yüzdelik değerleri, iki grup ortalaması arasındaki farkları belirlemede “t-testi”; ikiden fazla ortalamanın karşılaştırılmasında; tek yönlü varyans analizi kullanıldı Bulgular: Hastaların %68.1’i (n=49) HME nedeniyle bir veya daha fazla cerrahi girişim geçirmiş olgulardan oluşmaktaydı. Ağrı, hastaların %72.2’sinde (n=52) en belirgin şikayet idi. Ağrıyı başlatan en sık sebepler hastaların %52.8’inde koşma iken, %50’sinde kontakt sporlar (futbol, basketbol vb.) idi. Hastaların %31.9’u ağrının günlük yaşam aktivitelerini kısıtlayabildiğini bildirirken ortalama tüm gruplarda ortalama VAS skoru 7.4±2.4 idi. VAS skoru azaldıkça ÇDÖ puanlarında anlamlı bir artış tespit edildi. (p=0.005) Yüksek ÇDÖ ve HAM-D puanlarının geçirilen ameliyat sayısı (p=0.015), bir aydaki ağrılı gün sayısı (p&lt;0.001), düşük VAS skoru (p=0.005) ve ekstremitelerde yer alan lezyon sayıları (p=0.003) ile anlamlı olarak ilişkili olduğu belirlendi. Sonuç: Ağrı pediatrik HME hastalarında sosyokültürel aktiviteleri ve etkileşimi kısıtlayabilen en önemli sorunlardan biridir. Geçirilen ameliyat sayısı, bir ayda yaşanan ağrılı gün sayısı, düşük VAS skorları ve artmış lezyon sayıları HME hastalarında yaşam kalitesini negatif etkileyen ve pediatrik yaş grubunda depresyona yol açabilen faktörlerdir. HME hastalığın süresi pediatrik hastalarda depresyon ile ilişkilidir.

Authors: CALİS Aliye Gamze , OGUS Aliye Candan 
Published: October 2019

Aim: Pulmonary thromboembolism is a disease with high mortality and morbidity. In this study, the impacts of serum sodium, glucose and creatinine levels on prognosis were investigated. Patients and Methods: The data of the patients with PTE who received treatment between January 2010 and December 2012 were analyzed retrospectively. Routine laboratory values, arterial blood gas and transthoracic echocardiography results at the time of admission and 30-day mortality rates were recorded. Results: The mean serum sodium level and eGFR in the group with high mortality were significantly lower compared to the other group, while the serum glucose level was higher. When the compatibility of these markers with PESI was examined, it was found that serum sodium level and eGFR were lower and serum glucose level was higher in PESI class V compared to the other classes, and this difference was statistically significant. Conclusion: In this study, it was found that serum sodium, glucose and eGFR levels, which have the advantage of availability in every center, were compatible with RVD, troponin and PESI parameters that were previously proven prognostic factors in determining the mortality risk in acute PTE.
Yumurta Alerjisi Olan Süt Çocuklarında Kızamık Kızamıkçık Kabakulak Aşılama Deneyimi
Authors: HAZAR SAYAR Esra 
Published: October 2019

Amaç: Besin alerjisi sıklığı dünya genelinde artış göstermektedir. Yumurta alerjisi süt alerjisinden sonra çocuklarda 2. sıklıkta görülmektedir. Kızamık, kızamıkçık, kabakulak (KKK) aşısı, kızamık ve kabakulak virüsünün tavuk embriyo kültürlerinde üretilmesi nedeniyle eser miktarda yumurta proteini içermektedir. Bu nedenle yumurta alerjisi olan çocuklarda aşılamada çekinceler oluşmaktadır. Çalışmamızda yumurta alerjisi nedeniyle değerlendirilen süt çocuklarının 1 yaş KKK aşılaması sonrasında yan etkilerinin değerlendirilmesi amaçlanmıştır.Yöntem: Hastanemiz Çocuk Alerji İmmünoloji polikliniğinde Şubat 2018- Nisan 2019 tarihleri arasında yumurta alerjisi nedeniyle takip edilen ve kliniğimizde 12. ayda KKK aşısı uygulanmış olan 44 olgu çalışmaya alındı. Olguların demografik verileri, klinik bulguları, cilt prick testleri, bakılmış olan vakaların total IgE, eozinofil, alerjen spesifik IgE düzeyleri, aşılama sonrası yan etki profilleri retrospektif olarak değerlendirildi.Bulgular: Olguların 24’ü (%54,5) kız, 20’si (%45,5) erkekti. Hastaların 31’inde (% 70,4) atopik dermatit, 7’sinde (%15,9) ürtiker/döküntü, 6’sında (%13,6) reaktif havayolu hastalığı tanıları mevcuttu. Olguların cilt prick testlerinde; 31 olguda (% 70,5) yumurta beyazı, 26 olguda (%59,1) yumurta sarısı ile pozitif reaksiyon saptanmıştı. KKK aşılaması yapılan 44 süt çocuğundan 4’ünde (%9) reaksiyon gözlenmiş olup 3 olguda ilk 4 saatte, 1 olguda ilk 24 saatte reaksiyon gelişmiştir. Olguların hiçbirinde hayatı tehdit eden ciddi reaksiyon gözlenmemiştir.Sonuç: Bağışıklamanın önemi dikkate alındığında; anaflaksi riskinin düşük olması nedeniyle yumurta alerjisi olan çocuklarda aşı güvenle yapılabilir. Ancak atopik çocuklarda aşının, acil müdahale edilebilecek uygun koşullarda yapılması ve uygun süre gözlem altında kalmalarının önemli olduğunu düşünüyoruz.

Published: October 2019

Aim: Primary hyperparathyroidism (PHP) is associated with systemic inflam-mation. The effect of parathyroidectomy (PTX) on inflammatory markers is contro-versial. The aim of our study was to investigate changes in inflammatory markers including C-reactive protein (hs-CRP), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) before and after PTX. Patients and Methods: PHP patients (n=55) and age and sex matched healthy controls (n=50) were included in the study. The clinical and laboratory results of the PHP and control groups were compared before PTX and 6-months after PTX.Results: At baseline, serum hs-CRP (4.01±3.44 vs. 2.48±1.73 mg/L), PLR (127.21±25.77 vs. 103.63±32.52), RDW (15.50±2.53 % vs. 13.49±0.70 %) values were higher in the PHP group than in the control group (p&lt;0.05). After PTX, hs-CRP (3.59±3.07 mg/L), PLR (123.03±31.94), RDW (14.25±1.51 %) values did not change (p&gt;0.05). Post-PTX hs-CRP, PLR, and RDW values were higher in the PHP group than in the control group (p&lt;0.05). PTH value was positively correlated with pre-PTX hs-CRP (r2=0.377, p=0.001), PLR (r2=0.234, p=0.023), RDW (r2=0.296, p=0.004).Conclusion: Before PTX, inflammatory markers were higher in PHP patients com-pared with healthy controls. After PTX, the inflammatory markers did not significantly decrease; however these postoperative markers were higher than controls. İnflam-mation occurs in PHP patients, and also shows a partial recovery from inflammation despite successful surgery.

Abstract: Spinal epidural abscess is a rare pathology which is manifested by a classic triad of pain, fever and neurological deficit. In most cases, the clinical picture is incomplete which makes its diagnosis difficult. In this retrospective study, we report five cases of spinal epidural abscess treated in the neurosurgery department of Hassan II University Hospital of Fez. Four of our patients were admitted due to spinal cord compression, while one patient was admitted for isolated spinal syndrome without neurological deficit. Fever was present in all our patients, nevertheless no point of entry was identified in the initial assessment. MRI was performed on emergency basis in all of our patients which demonstrated an extra-dural hypo intensity on T1WI, hyper intensity on T2WI. It also showed lesions with peripheral enhancement after contrast with gadolinium. Four of our patients underwent surgical treatment which involved performing alaminectomy/laminotomy with drainage of the abscess, while one patient received medical treatment alone. The evolution was favorable in 4 of our patients while one patient died post operatively due to severe sepsis.

Published: October 2019

Background: Alzheimer’s disease is the principal cause of dementia and is determined, in at least one third cases, by modifiable risk factors (MRF). The “Lifestyle for Brain Health (LIBRA)” index was recently developed to quantify the individual risk of progression to dementia ascribable to MRF. Objective: The aim of this study was to investigate the association between LIBRA scores and markers of cognitive performance, functional independence, and psycho-behavioral symptoms in a community-based sample of Italian elders. Methods: 308 senior participants with mild cognitive impairment (MCI) or subjective cognitive decline (SCD) were evaluated with a complete neuropsychological battery and semi-structured interviews for the assessment of depression, apathy, and functional autonomy. All the 12 LIBRA MRF were available for the calculation of LIBRA scores. A modified version of the index (LIBRA-2) was calculated by removing depression weight from the LIBRA index. Partial correlation analyses, controlling for age and education, assessed the association between LIBRA indices and cognitive, functional, and behavioral outcomes. Separate analyses were repeated in the MCI and SCD subgroups. Results: In participants with SCD (SCDp), significant correlations existed between LIBRA and markers of impairment in global cognition, visuo-spatial attention, and semantic fluency. LIBRA-2 associated with psycho-behavioral symptoms in the whole sample and in SCDp. LIBRA-2 only associated with apathy in the MCI subgroup. Conclusions: The LIBRA index might be useful to determine the lifestyle-attributable risk of cognitive and psycho-behavioral decline in Italian seniors at risk, while in those with overt cognitive impairment, these outcomes are presumably mainly associated with non-modifiable factors.
